Recurrent Depressive Disorder is a chronic condition that significantly impacts the quality of life. Despite various treatment options, some patients face severe and treatment-resistant relapses. This case is related to research on ketamine in Electroconvulsive Therapy (ECT) for RDD. One study highlighted the efficacy and safety of ketamine compared to other anaesthetic agents in ECT for major depression. Additionally, another study explored subanesthetic doses of ketamine before each ECT session to improve therapeutic outcomes and sleep quality in patients with major depressive disorder.

To present a clinical case of a patient with Recurrent Depressive Disorder (RDD) who improved following a change in the Electroconvulsive Therapy (ECT) protocol using ketamine as an anaesthetic inducer.

We examined the patient’s medical records, including her medical history, previous treatments, and therapeutic responses.

A 65-year-old childless woman with a history of stroke, bilateral carotid atheromatosis, and hypothyroidism suffered from RDD. Despite multiple prior treatments and ECT, she experienced a severe depressive relapse. Eight intensive ECT sessions were administered, with observed memory lapses. Due to the lack of response, the anaesthetic inducer etomidate was replaced with ketamine, resulting in a positive response. The patient continued pharmacological treatment with improved mood, but recent and evident memory alterations persisted, possibly related to anterograde amnesia.

This case highlights the complexity of RDD in patients with comorbidities and treatment-resistant relapses. The change in the ECT protocol using ketamine was effective, emphasizing the importance of alternative therapeutic approaches in refractory cases. The successful treatment of RDD in this patient using ketamine in ECT underscores the need for personalized therapeutic options in treatment-resistant patients. These scientific resources reinforce the relevance of exploring therapeutic alternatives in contemporary clinical practice. We need more research to understand the underlying mechanisms and how this approach could be enhanced in similar cases.

Schizotypal personality is a condition suffered by 4% of the population. It is defined by presenting interpersonal, behavioral and perceptual features similar to the clinical features of psychotic disorders, such as schizophrenia, in less intensity and dysfunctionality, but at risk of reaching psychosis.

Presentation of a clinical case about a patient with premorbid schizotypal personality traits presenting with an acute psychotic episode.

Literature review on association between schizotypal personality and psychosis.

A 57-year-old woman with a history of adaptive disorder due to work problems 13 years ago, currently without psychopharmacological treatment, goes to the emergency room brought by the emergency services due to behavioral alteration. She reports that “her husband and son wanted to sexually abuse her”, so she had to run away from home and has been running through the streets of the town without clothes and barefoot.

Her husband relates attitude alterations and extravagant behaviors of years of evolution, such as going on diets of eating only bread for 40 days or talking about exoteric and religious subjects, as believing that the devil got inside her husband through a dental implant. He reports that these behaviors have been accentuated during the last month. She has also created a tarot website, and has even had discussions with several users. She is increasingly suspicious of him, has stopped talking to him and stays in his room all day long, with unmotivated laughter and soliloquies.

It was decided to admit him to Psychiatry and risperidone 4 mg was started. At the beginning, she was suspicious and reticent in the interview. As the days went by, communication improved, she showed a relaxed gesture and distanced herself from the delirious ideation, criticizing the episode.

In recent years, there has been increasing interest in understanding the association between schizotypy and serious mental disorder. Several theories understand schizotypy as a natural continuum of personality that reveals genetic vulnerability and that can lead to psychotic disorder when added to precipitating factors. Other theories define schizotypy as a “latent schizophrenia” where symptoms are contained and expressed in less intensity.

Around 20% evolves to paranoid schizophrenia or other serious mental disorders. It is complex to distinguish between those individuals in whom schizotypy is a prodrome and those in whom it is a stable personality trait. To date, studies applying early psychotherapeutic or pharmacological interventions have had insufficient and contradictory results, and the follow-up and treatment of these individuals could be a stress factor and a stigma. Some studies are looking for reliable markers of evolution to schizophrenia in order to establish adequate protocols for detention, follow-up and treatment.

Liver cirrhosis, a chronic liver disease, can be closely linked to chronic alcohol abuse, posing a significant medical challenge. Hepatic encephalopathy (HE), a neuropsychiatric condition resulting from liver dysfunction, commonly occurs in cirrhotic patients due to the accumulation of neurotoxic substances like ammonia and manganese in the body. Managing cirrhosis and alcohol addiction is crucial to enhancing the quality of life for these patients, as HE can manifest in various ways and with varying degrees of severity.

To emphasize the importance of recognizing and treating hepatic encephalopathy as a potential complication of liver cirrhosis and sedatives during alcohol withdrawal.

We compiled clinical data, medical history, neuroimaging tests, and therapeutic interventions applied.

A 55-year-old man with a complex medical history, including Child-Pugh B liver cirrhosis, portal hypertension, hypertension, diabetes mellitus, and chronic alcohol abuse with numerous prior hospitalizations for acute pancreatitis and severe head trauma related to alcohol consumption, presented to the emergency department with symptoms of alcohol withdrawal and suicidal thoughts, leading to lorazepam administration and a recommendation for admission to a specialized Therapeutic Community. After 72 hours, he developed hepatic encephalopathy with symptoms such as confusion, sleep disturbance, sweet-smelling breath, abnormal hand movements, conjunctival icterus, and urinary difficulties.

An EEG revealed a globally attenuated and disorganized bioelectrical activity with triphasic waves. The magnetic resonance imaging showed signs of hepato-cerebral degeneration, including T1-weighted hyperintensity in the lentiform and mesencephalic nuclei due to manganese deposition. Treatment was adjusted to reduce sedative use, and therapy with Rifaximin and Lactulose was initiated to control blood ammonia levels. After a week, the patient exhibited significant neurological improvement, underscoring the importance of appropriate management in patients with hepatic encephalopathy related to liver cirrhosis and chronic alcohol abuse.

This case underscores the complexity of HE in patients with liver cirrhosis and alcohol dependence. HE can present in various ways, from subtle symptoms to severe episodes of confusion and coma. Findings on EEG, such as triphasic waves, are characteristic of HE and reflect brain dysfunction. Furthermore, manganese accumulation in the brain, as evidenced by magnetic resonance imaging, may contribute to neurological symptoms in cirrhotic patients. In this context, the early recognition and multidisciplinary treatment are emphasized to improve the quality of life and prevent the progression of this neuropsychiatric complication. EEG and magnetic resonance imaging findings play an essential role in the evaluation of these patients.

We present the case of a 48-year-old woman, a nurse, referred from the Internal Medicine department for evaluation of depressive symptoms and accompanying somatic presentation following COVID-19. The aim is to highlight a recently emerging condition that we are increasingly encountering in our clinics, which can complicate the diagnosis of an underlying affective disorder

Diagnosed with COVID-19, confirmed by a positive PCR test, 6 months ago following an infection in the workplace. The clinical picture consisted of mild symptoms, with a ten-day course and apparent resolution at the time of hospitalization. She returned to her work activities and gradually began to report fluctuating symptoms, including headaches, mild shortness of breath, fatigue, as well as a tingling sensation in the upper extremities, especially in the hands. Additionally, she described feelings of restlessness, depressive mood, and intense fatigue. In additional tests: (CT-Scan) there are signs of mild bilateral lower lung fibrosis.

Treatment with Duloxetine was initiated for a case of depressive symptoms with accompanying physical symptoms. The differential diagnosis considered Major Depressive Disorder, Single Episode, and Adjustment Disorder with Depressed Mood.”

We are facing a clear case of depressive clinic that may have endogenous features, if we adhere to criteria such as those in the DSM-5, as it would meet the criteria for Major Depressive Disorder, Single Episode. However, we have a clearly identified trigger, so we also need to perform a differential diagnosis, primarily with Adjustment Disorder with Depressed Mood: here, the symptoms appear within 3 months following the stressful agent (in this case, SARS-CoV-2 infection). Unlike Major Depressive Episode, once the agent has ceased, the symptoms do not persist beyond 6 months (which we do not know because the physical symptoms causing disability have not disappeared).In addition to purely psychiatric diagnoses that we are accustomed to, we must consider a new diagnostic entity that is becoming more prevalent as the pandemic progresses, namely “long-covid” or persistent COVID.These are generally middle-aged women who, several months after infection, continue to manifest a multifactorial complex of symptoms. These symptoms persist over time, not only the classical ones but also many others that can appear during the ongoing course of the disease.

Beyond the purely psychiatric diagnoses we are accustomed to, we must also consider a new diagnostic entity that is becoming more prevalent as the pandemic continues to advance: Persistent COVID or ‘long-COVID.’ Generally, this condition affects middle-aged women who, several months after contracting the virus, continue to exhibit a multifactorial complex of symptoms. The most common symptoms include fatigue/asthenia (95.91%); general discomfort (95.47%); headaches (86.53%); and low mood (86.21%)

Pregnancy is a high-risk period for major affective disorders and can lead to a destabilizing period for our patients. Standard pharmacological strategies must be carefully evaluated due to potential teratogenic or side effects. We present a case of bipolar disorder type I with challenging-to-control maniac episodes during pregnancy, which has required Electroconvulsive Therapy for its management.

Presenting maintenance electroconvulsive therapy (ECT) as a safe and effective therapeutic strategy during pregnancy, with the presentation of a case in which it has been administered every 3 weeks from the second trimester until the baby’s birth at 37 weeks

This concerns a 28-year-old immigrant woman, married, with a 10-year-old child. She was diagnosed with bipolar disorder type I at the age of 16 when she experienced her first manic episode in her country of origin. Subsequently, during her first pregnancy, she required hospitalization for electroconvulsive therapy (ECT) treatment, with a positive response after a single session. She remained stable for several years without maintenance pharmacological treatment or follow-up until the ninth week of her second pregnancy when she experienced a manic episode requiring hospitalization.

She was initially treated with Olanzapine and Lorazepam with a positive response, but three weeks later, she was readmitted with a similar episode. These decompensations occurred almost monthly, leading to the consideration of introducing mood stabilizers after the first trimester. However, due to the patient’s severe hyperemesis gravidarum, this stabilizing treatment was ruled out due to the difficulty in controlling its blood levels and the associated risk of intoxication. During the fifth admission at the 20th week of gestation, the decision was made to initiate ECT treatment, which yielded an excellent response and subsequent maintenance.

The indications for electroconvulsive therapy (ECT) during pregnancy are the same as in the rest of adult patients. In individuals with a psychiatric history, it is possible for a relapse of mental illness to occur during pregnancy, although the risk is considerably higher during the postpartum period. ECT is considered an effective and safe treatment option in all three trimesters of pregnancy and the postpartum period. During the informed consent process, patients should be informed about the potential impact of ECT as well as alternative treatment options.

Lithium nephropathy can occur in long-term lithium-treated bipolar disorder patients. Key risk factors include duration of lithium exposure, cumulative dose, acute intoxication episodes, advanced age, and comorbidities such as hypertension, diabetes mellitus, hyperparathyroidism, and hyperuricemia, along with concurrent use of antipsychotics. The clinical presentation is gradual, with mild proteinuria, often accompanied by arginine vasopressin resistance. Histological studies show a correlation between interstitial fibrosis and cumulative lithium duration. Approximately 15 to 25 per cent of exposed patients may experience a gradual decline in glomerular filtration rate. The outcome after lithium discontinuation varies.

This case study aims to analyze and document the clinical presentation, diagnosis, and management of lithium nephropathy in a patient with Bipolar Disorder.

We gathered data on the medical history, lab results, and treatment approach for a patient with Bipolar Disorder.

The patient, a 50-year-old woman, had been under the care of Psychiatry since 2008 due to a diagnosis of Bipolar Disorder Type I. During this time, she had experienced depressive and manic episodes but had not presented significant symptom decompensation for the past 14 years, successfully managed with lithium at a current dose of 600 mg per day. However, on this occasion, the patient sought hospitalization due to recent behavioural disturbances, including restlessness, disinhibition, abrupt changes in behaviour, pressured speech, sleep problems, agitation, and aggression. The patient also reported an increased sense of polyuria and polydipsia. Evaluation in the emergency department revealed elevated lithium levels of 1.47 mmol/L and hypokalemia, that justified lithium withdrawal. After lithium levels decreased, an estimated glomerular filtration rate remained low. She was diagnosed with lithium nephropathy, an adverse effect of long-term lithium therapy. Treatment with lithium changed to sodium valproate. Treatment with asenapine started and sustained for two months. Over the following two years, the patient experienced four additional hospital admissions in Psychiatry due to manic episodes.

Long-term lithium therapy can lead to lithium nephropathy with symptoms such as polyuria, polydipsia, and acute kidney failure. Consistent monitoring of patients receiving lithium is crucial to detect potential adverse effects.This case highlights the challenges in managing bipolar patients, as discontinuing lithium exacerbated symptoms despite switching to sodium valproate for nephropathy prevention. Long-term lithium treatment, while effective for bipolar disorder, poses significant renal risks. We emphasize continuous renal function monitoring and assessing the risk-benefit of lithium treatment while actively researching lithium nephropathy and its impact on glomerular function.

Hospital readmissions in psychosis are a critical concern, with medication choice playing a vital role. Oral antipsychotics, though common, rely on patient adherence and can lead to relapses if not followed. Long-acting injectable atypical antipsychotics (LAIAs) provide an alternative, ensuring consistent medication release and reducing relapse risk due to missed doses. Studies indicate that LAIAs result in fewer readmissions due to improved adherence. Tailoring treatment to individual needs is essential. Medication choice significantly influences hospital readmission prevention in psychosis. LAIAs, which could offer greater adherence to treatment and symptom control, present a promising option. Individualized treatment decisions are a priority for long-term recovery.

This study aimed to compare the hospital readmission rates within two years post-discharge among two groups of patients diagnosed with schizophrenia and other psychotic disorders who received either oral antipsychotic treatment or LAIAs.

We collected sociodemographic and hospitalization data from 155 patients, 90 receiving oral antipsychotics and 65 receiving LAIAs, following their discharge from a psychiatric unit.

There were 90 patients in the oral treatment group, and 65 in the LAIA group, with 67.6% receiving paliperidone and 26.1% receiving aripiprazole. There were no significant differences in age or gender between the two groups. However, patients in the LAIA group had longer stays in the hospital (M=14.7; SD=10.2 vs M=11.1; SD=6.4; t(153)=2.67; p<.01) and a higher number of prior admissions (M=3.2; SD=3.7 vs M=1.3; SD=3.5; t(153)=2.41; p<.01) compared to the oral antipsychotic group. Additionally, a higher percentage of patients in the LAIA group were diagnosed with schizophrenia (60%) compared to the oral antipsychotic group (24%) (X2 (1, N = 155)= 20.4, p<.01). After two years, readmission rates were 66.6% for the oral antipsychotic group and 61.5% for the LAIA group (X2 (1, N = 155)= 8.5, p > .05). However, the time to readmission was shorter for patients on oral antipsychotics (M=172.4; SD=162.0) compared to those on LAIAs (M=326.2; SD=211.4; t(153)=3.05; p<.01). Notably, 86.6% of patients on oral antipsychotics were readmitted within the first year, while only 52% of those on LAIAs experienced readmission during the same period (X2 (1, N = 155)= 8.5, p = .001).

Long-acting injectable antipsychotics (LAIAs) appear to reduce hospital readmissions, with a more pronounced effect in the first few months post-discharge. However, after two years, the readmission rates between LAIAs and oral antipsychotics become comparable. This data suggests that while LAIAs may reduce early readmissions, their long-term effectiveness is on par with oral antipsychotics.

Gynecomastia refers to the abnormal development of breast tissue in males, often posing a concerning symptom. Often, gynecomastia is associated with multiple factors, including the use of various drugs, notably certain atypical antipsychotics. Gynecomastia is a significant side effect that affects the quality of life of male patients taking antipsychotic medications. Among these, risperidone and paliperidone have been identified as the most prone to causing gynecomastia, although aripiprazole has garnered attention for its superior profile in controlling prolactin and gynecomastia. The relationship between these drugs and the development of gynecomastia lies in their ability to elevate prolactin levels, a hormone that regulates reproductive function and is involved in milk production. Several studies have shown that prolactin levels are more commonly elevated with risperidone and paliperidone prescription, thus triggering gynecomastia.

The study aims to investigate the management of gynecomastia in male patients receiving antipsychotic medications.

This research employs a retrospective analysis of patient records to examine the association between specific antipsychotic drugs, prolactin levels, and the development of gynecomastia, while also evaluating the effectiveness of aripiprazole as an alternative treatment.

We present the case of a 21-year-old male with no prior medical history who initiated treatment with oral paliperidone and later switched to 100 mg of long-acting injectable paliperidone once monthly during his initial admission for psychotic symptoms. After six months, he developed gynecomastia, which was ruled out as breast tissue and was determined to be an increase in adipose tissue. Since his hospital discharge, he has gained 25 kg (30%) in body weight, and his baseline prolactin level has decreased. This weight gain, a common side effect of several antipsychotics, was linked to gynecomastia. However, a promising approach for gynecomastia antipsychotic-associated treatment is aripiprazole, which has a milder impact on prolactin levels. In this case, during the next appointment, a switch to 400 mg of long-acting injectable aripiprazole once-monthly was made, which led to weight loss, a reduction in breast size and blood prolactin levels in the following weeks.

The detection and management of gynecomastia in these patients are crucial to improving their quality of life and treatment adherence. This management encompasses changes in medication, hormonal therapy, or surgery in severe cases. Physicians must be aware of this potential complication when prescribing antipsychotics and closely monitor at-risk patients. In summary, antipsychotic-associated gynecomastia in men represents a medical challenge that requires careful attention and an individualized treatment strategy for each affected patient.

During cannabis use, some individuals may experience psychotic symptoms, such as unusual perceptions or irrational thoughts, including mild hallucinations or temporary paranoia. Anxiety is also common, characterized by excessive worry or intense fear. The occurrence of these symptoms varies based on cannabis quantity, individual sensitivity, and surroundings. Although not all users experience these effects, the link between cannabis and psychotic or anxiety symptoms highlights the need for a thorough risk assessment.

Our goal is to analyze trends in cannabis use, as well as the psychotic and anxiety symptoms experienced by users, and to examine whether cannabis use is associated with other substances consumption.

We collected demographic and substance consumption data from two groups: 29 individuals aged 18 to 28 who had tried cannabis at least once and 19 regular consumers through a structured questionnaire.

Regular cannabis consumers had a higher proportion of males than those who had tried it once (X²(1)=4.81; p=0.028). There were no significant differences in age, alcohol or tobacco consumption between the groups. Notably, regular cannabis consumers had a history of using other illegal drugs, both in the past and within the last month (X²(1)=8.53; p=0.003). Regarding cannabis effects, regular users more frequently reported sensations like euphoria, relaxation, altered time perception, tachycardia, motor coordination difficulties, and impaired clear thinking compared to one-time users (X²(1)=10.12; p=0.001). Regarding anxiety symptoms during cannabis consumption, both groups experienced a similar frequency. Finally, regular cannabis consumers reported strange ideas or perceptions more often than one-time users (X²(1)=0.743; p=0.019). However, the associated discomfort level was similar in both groups.

This study highlights that regular cannabis use is associated with a greater likelihood of using other substances and experiencing more pronounced effects, including psychotic symptoms. However, it doesn’t necessarily lead to increased anxiety symptoms compared to one-time users. It’s important to acknowledge that the relationship between cannabis and psychosis is intricate and influenced by factors like consumption quantity and individual sensitivity. These findings stress the importance of understanding cannabis’s impact on mental health and its connection to the use of other substances.

Delusional parasitosis, also known as delusional infestation or Ekbom’s syndrome, is a rare psychotic disorder characterized by the false belief that a parasitic skin infestation exists, despite the absence of any medical evidence to support this claim. These patients often see many physicians, so a multidisciplinary approach among clinicians is important. Many patients refuse any treatment due to their firm belief that they suffer from an infestation, not a psychiatric condition, so it is crucial to gain the trust of these patients.

The comprehensive review of this clinical case aims to investigate Ekbom syndrome, from a historical, clinical and therapeutic perspective.

Literature review based on delusional parasitosis.

A 65-year-old woman comes to the psychiatry consultation referred by her primary care physician concerned about being infested by insects that she perceives through scales on her skin for the last three months. She recognizes important impact on her functionality. She is also convinced that her family is being infected too. As psychiatric history she recognizes alcohol abuse in the past (no current consumption) and an episode of persecutory characteristics with a neighbor, more than ten years ago. On psychopathological examination, she shows delusional ideation of parasitosis, with high behavioral repercussions, cenesthetic and cotariform hallucinations, as well as feelings of helplessness and anger. Treatment with Pimozide was started and the patient was referred to dermatology for evaluation, a plan she accepted. Her primary care physician and dermatology specialist were informed about the case and the treatment plan. In the recent reviews, the patient is calmer, however, despite the corroboration of dermatology and in the absence of organic lesions in cranial CT, she is still unsatisfied with the results, remaining firm in her conviction of infestation. It was decided to start treatment with atypical neuroleptics (Aripiprazole), with progressive recovery of her previous functionality.

Despite the increase in the number of studies in recent years, there are still few studies on this type of delirium. The female:male ratio varies in the bibiliography (between 2:1 and 3:1). The onset is usually insidious, generally appearing as a patient who comes to his primary care physician convinced of having parasites in different skin locations. It is usual to observe scratching lesions or even wounds in search of the parasite. In the past, the most used and studied treatment was Pimozide. Currently the treatment of choice is atypical neuroleptics due to their lower side effects. The latest reviews on the prognosis of this disorder show data with percentages of complete recovery between 51% and 70%, and partial responses between 16.5% and 20%. Finally, for a good diagnosis and therapeutic management, it is important to achieve a multidisciplinary approach.

Epidemiological studies have established a complex relationship between cannabis consumption and a heightened risk of psychotic disorders, including schizophrenia. However, this connection is multifaceted, influenced by genetics, environment, and individual psychology. Surprisingly, despite a surge in emergency room (ER) visits associated with cannabis consumption and psychosis, there haven’t been significant increases in hospital readmissions. This rise in ER visits can be attributed to the increasing social acceptance of cannabis and its legalization in some regions, increasing the likelihood of adverse effects. Furthermore, the higher potency of contemporary cannabis can trigger psychotic reactions, particularly in those consuming elevated levels of THC, its primary psychoactive component.

This study aimed to compare the rates of readmissions and ER visits one year after hospital discharge among patients diagnosed with schizophrenia and other psychotic disorders, stratified by cannabis consumption.

We collected sociodemographic and clinical data from 109 patients after discharge from a psychiatric hospitalization unit.

Patients who consumed cannabis (N=35) were younger than non-consumers (M=31.4; SD=10.0 vs M=44.3; SD=11.4; t(107)=5.71; p<.01), with no significant gender differences, hospital stay durations, or proportions of schizophrenia diagnoses (33.3%). The readmission rates and time to readmission were similar between both groups. Interestingly, 54.2% of cannabis consumers required emergency care (X2 (1, N = 109)= 4.1, p = .04), with 73.6% not needing admission (X2 (1, N = 109)= 5.5, p = .01), in contrast to 33.7% and 56% in the non-consumer group. The time to the first urgent care visit was shorter in the consumer group (M=59.5; SD=56.3) compared to the non-consumer group (M=105.8; SD=93.1; t(107)=1.92; p=.03).

This study reveals that patients with psychosis and cannabis consumption tend to visit ER services more frequently despite utilizing fewer hospital resources like hospitalizations. Notably, despite the increased ER visits, there hasn’t been a corresponding rise in hospital readmissions. These would be due to individuals experiencing cannabis-related psychotic episodes receiving suitable assessment and treatment in the ER, obviating the need for prolonged hospitalization. Furthermore, some psychotic episodes may naturally resolve over time, particularly with reduced or discontinued cannabis consumption. Our result highlights the need for personalized care approaches targeting this group, effectively addressing acute episodes related to cannabis use and psychosis. Addressing this trend requires a multidisciplinary approach involving mental health professionals, addiction specialists, and emergency response teams.

Esketamine, an active Ketamine isomeric form that indirectly inhibits the GABAergic neuronal pathways, has been recently approved to treated severe, resistant depressive disorders. Here, we present the case of a 64 years old woman diagnosed with severe, resistant depression and an initial score of 28 points in the Hamilton Depression Rating Scale who was treated with Esketamine with excellent response and a HDRS of 8 points after 4 months.

To expose our experience with the first patient treated with Esketamine in our Hospital.

Describing the patient’s patobiography and the different treatments lines tried in first place and exposing the experience among Ketamine treatment and the final results.

We present the case of a 64 years old woman, divorced and retired, who lives with her son since the aggravation of the depressive symptomatology, with no medical nor surgical background and no history in Mental Health before her first psychiatric internment in 2020. Between February 2020 and June 2023, 5 different treatments options with supervise intake were tried, including increment of the dose, antidepressant rotation, the combination of Desvenlafaxine + Mirtazapine and adding Topiramate and Lithium, with no improvement. Among this years, 3 psychiatric internments were needed because of the depressive symptoms and 1 more hospitalization in Internal Medicine was required because of the patients severe, malnutritional state. In June 2023 and after two complete analysis, a MR and a score of 28 points in the Hamilton Depression Rating Scale treatment with Esketamine was started with no incidences. She described one dissociative episode during which she assures “she was surrounded by soft, rubbery, yellow bubbles”. After 4 months of treatment the patient has recovered her previous functional rate and has an 8 points score in the HDRS.

In conclusion, we can affirm that Esketamine is an effective and secure option for Resistant Depresion Dissorder. Nevertheless, Before considering a Depressive Episode as “resistant to treatment”, treatment adherence and other medical, surgical and psychiatric comorbidities must be studied.

Lithium treatment is a proven method for bipolar disorder management, but its narrow therapeutic range and the risk of severe side effects, including lithium intoxication, pose significant clinical hurdles. Lithium intoxication, a potentially life-threatening complication, can occur during treatment, raising ongoing questions about its clinical factors, risk elements, and best practices for management.

Our objective is a comparative analysis between patients who have experienced lithium intoxication and those who have not, aiming to identify influencing factors and enhance clinical care.

We collected demographic data, age at lithium treatment initiation, treatment duration, therapeutic adherence, Mental Health consultations, and lithium level monitoring from 14 individuals requiring clinical attention due to lithium intoxication and 14 patients with similar gender, age, and diagnosis with lithium treatment but without intoxication during four years of follow-up.

Regarding the results, the age of onset of lithium treatment in patients with lithium intoxication was 30.2 years (SD=8), and the duration of lithium treatment averaged 11.1 years (SD=8.8), which did not significantly differ from the control group with ages of onset at 38.1 years (SD=15.1) and treatment duration of 9.27 years (SD=8.8), respectively. Lithium intoxication patients developed severe complications, including hospitalizations in medical-surgical units, the necessity for dialysis, and death, one fatal case. Although therapeutic adherence to lithium, measured through pharmaceutical dispensation, exceeded 90% and was comparable in both groups, patients affected by lithium intoxication exhibited a significantly higher treatment discontinuation rate (OR 32.5; 95% CI, 3.1 to 337.8) during the follow-up period. Patients who experienced lithium intoxication had an average of psychiatric consultations every 11.2 months (SD=13.4), with 35.7% not attending at least once a year, while the control group had an appointment every 5.31 months (SD=2.7) (p > 0.05). Lastly, despite both groups having a similar frequency of plasma lithium level monitoring, occurring approximately every 5.5 months (SD=2.6) and 7.8 months (SD=4.8), respectively, in 28.5% of those who suffered from lithium intoxication did not undergo any monitoring for periods exceeding 18 months (p < 0.05).

Our research highlights the significance of delivering thorough clinical care and continuous monitoring to patients receiving lithium treatment for bipolar disorder. Ensuring effectiveness therapeutic adherence and maintaining strict monitoring of lithium levels are critical factors that significantly enhance treatment safety. Appropriate management has the potential to improve the quality and safety of care for people with bipolar disorder who are dependent on lithium therapy.

Delirium is common and is associated with many adverse short-term consequences as increased hospital costs, health care complications, and increased mortality. Long-term cognition consequences on delirium have not been well synthesized and quantified.

Our study aims to determine the relationship between an episode of delirium and subsequent dementia and death over five years.

Postoperative delirium, previous psychiatric disorders, mental health service use, and death data collected from a cohort of inpatients diagnosed with delirium that requires psychiatric attendance in a general hospital were analyzed. Between 2009 and 2011, we started a follow-up of 91 patients aged 65 years or older at baseline for 60 months.

Five patients (5.4%) were diagnosed with dementia previously. During the first year, 35 patients without previous dementia (40.6%) died. More than half of the one-year survivors (27; 52.9%) were diagnosed with dementia at the follow-up. Differences in age (79,5 vs 80.3; Z=-0.07; p=0.93), survival time (54.8 vs 48.8;Z=1.30;p=0.19), postoperative delirium rates (74%vs66.6%; χ2=0.33, DF=1, p=0.56) and mental disorder antecedents were not found. Patients with dementia after delirium were more likely to be attentive in mental health services (48.1vs16.6%; χ2=5.666, DF=1, p=0.017).

In our study, delirium is an important risk marker for dementia and death and is significantly associated with the long-term cognitive decline in surgical and non-surgical patients. Subsequent follow-up in mental health service could help detect dementia after episodes of delirium and lead to fewer potentially harmful interventions such as hospitalization or antipsychotic medication. An important question to determine is whether delirium is simply a risk marker for dementia or whether the delirium could cause neuronal damage leading to dementia.

Maintenance electroconvulsive therapy (mECT) is an option in the treatment of affective disorders which progress is not satisfactory. It is certainly neglected and underused during the clinical practice.

To evaluate the efficacy of mECT in reducing recurrence and relapse in recurrent depression within a sample of three patients.

We followed up these patients among two years since they received the first set of electroconvulsive sessions. We applied the Beck Depression Inventory (BDI) in the succesives consultations for evaluating the progress.

The three patients were diagnosed with Recurrent Depressive Disorder (RDD). One of them is a 60 year old man that received initially a cycle of 12 sessions; since then he received 10 maintenance sessions. Other one is a 70 year old woman that received initially a cycle of 10 sessions; since then she received 6 maintenance sessions. The last one is a 55 year old woman that received initially a cycle of 14 sessions; since then she received 20 maintenance sessions.

All of them showed a significant reduction in depressive symptoms evaluated through BDI and clinical examination. In the first case, we found a reduction in the BDI from the first consultation to the last that goes from 60 to 12 points; in the second case, from 58 to 8 points; and in the last case, from 55 to 10 points. The main sections that improved were emotional, physical and delusional.

As side-effects of the treatment, we found anterograde amnesia, lack of concentration and loss of focus at all of them.

We find mECT as a very useful treatment for resistant cases of affective disorders like RDD.

It should be considered as a real therapeutic option when the first option drugs have been proved without success.

Coronavirus disease 2019 (COVID-19) modify voluntary admission rates to psychiatric wards in the early phases following pandemic onset. Older patients have higher COVID-19 distress scores because elderly people are at risk for COVID-19 infection.

The present investigation aimed at admission rates of elderly patients to a General Hospital Psychiatric Ward during the lockdown due to the COVID-19, compared to similar periods of 2018 and 2019.

Anonymized data on psychiatric admissions (n=55) from one general hospital psychiatric ward have been obtained and analysed. We compared admission characteristics between April and June of 2018 and 2019 with the same period of 2020 (lockdown).

During the COVID-19 lockdown, a significant reduction in psychiatric hospitalizations of older patients (aged >65 years) was observed in the lockdown (69.2%; χ2=4.823,df=1,p=0.028) in contrast with young patients (26.7% reduction). There was a reduction of 14% in admission due to suicidal behaviour (IRR = 0.57; 95% CI: 0.11-2.75; p=0.48), 25% in depression (IRR = 0.28; 95% CI: 0.64-1.25; p=0.09) and 50% in psychotic disorders (IRR = 0.33; 95% CI: 0.07-1.48; p=0.15). There was none admission by dementia during the lockdown.

Changes in the number of psychiatric admissions, particularly for older patients, were observed during the COVID-19 lockdown. During this period, their fear levels could modify their psychiatric admission rates. We suggest that the decrease of psychiatric admissions in the elderly was due to fear of contagion in hospitals.

Patients with an alcohol use disorder frequently relapse after various efforts to quit. Admission to hospital units is a possible start to stop drinking alcohol and reach abstinence. Among the pharmacological strategies to quit this addiction are specific drugs, such as disulfiram or namelfen, which are widely studied. Hospitalized patients frequently initiate these medications to control addiction, but little is known about their efficacy after discharge in this group.

The aim is to determine whether the initiation of treatment with specific drugs for alcohol use disorder could help to maintain alcohol abstinence after admission to a General Hospital Psychiatric Ward. In addition, we want to check those factors associated with a higher rate of relapse in consumption.

We conducted a retrospective cross-sectional study of a group of patients admitted in 2018 to a psychiatric hospitalization ward due to alcohol use disorder and who expressed their desire to stop drinking. At the time of admission, we recorded sociodemographic data, consumption of other substances and alcohol family history. Patients initialized specific treatments to reduce and control alcohol consumption if they wanted. Twenty-four months after discharge, we acquired the number of relapses through new admissions, emergency room visits or outpatient follow-up data.

A sample of 36 patients (28 men) admitted to a psychiatric hospitalization ward was analyzed. At discharge, 17 accepted specific pharmacological treatments to reduce alcohol consumption. After a follow-up period of 24 months, 70.8% relapsed compared to 94.7% who did not accept treatment (χ2=4.001, DF=1, p=0.045, OR=0.13). There were no differences between the two groups in age, gender, amount of alcohol consumed, follow-up modality at discharge or if it was their first detoxification attempt. However, those who did not accept the specific pharmacological treatment consumed other drugs (41.1% vs 5.8%, χ2= 5.888, DF=1, p=0.015), had other history of mental disorder (64.7% vs 23.5%, χ2= 5.845, FD=1, p=0.015) and a higher proportion of relatives with alcohol consumption (81.8% vs 42.8%, χ2= 3.896, FD=1, p=0.048) more frequently. The time (in days) to relapse was faster in this group of patients (200.8 vs 402.7 , Z=-2.5413, p=0.005).

Accepting drug-specific treatment for alcohol use can be helpful for many patients who want to achieve alcohol abstinence. Among the factors that prevent the acceptance of this treatment is the consumption of other substances, comorbidity with another mental pathology and family history, which may involve genetic factors that favour addiction. This group of patients could benefit from a specific pharmacological treatment, although other psychosocial factors may also help.

The presence of perceptual disturbances and psychotic symptoms associated with substance abuse are widely known. While the abuse of substances is becoming more widespread, there is a general perception that their use entails fewer risks. 25I-NBOMe is a recently introduced hallucinogenic drug producing visual hallucinations and euphoria. Although people consume it like LSD, its chemical structure is different to LSD. 25I-NBOMe is related to other phenylethylamine derivatives (amphetamines and mescaline).

Present a clinical case of psychosis triggered after the consumption of new emerging drugs and highlight that the extension of their consumption in the general population, especially in the most vulnerable, can trigger prolonged psychotic symptoms.

We present a clinical case report of a subject who developed perceptual disturbances and paranoid symptoms. These lasted for months.

We describe the case of a 30-year-old man who required psychiatric admission after a single NBOMe intake five months earlier. He began with self-referential experiences and delusional ideas of prejudice, persecution and control in social networks. For months, intrusive images appeared in the form of flashbacks. He remains isolated, hardly sleeps and is easily irritated. He previously worked and had a well social network. Since adolescence, he had occasionally used alcohol, cannabis and cocaine. An uncle was diagnosed with schizophrenia. Treatment with long-term injectable aripiprazole started, reducing the symptoms and managing to recover work activity in a year.

25I-NBOMe has its main activity as 5HT2 receptor agonism, which is associated with increased dopaminergic activity in the brain. Hallucinations, delusions, anxiety symptoms and depersonalization appear during acute consumption. However, some patients have developed a persistent hallucinatory chronic syndrome after consumption. As its use is expanding, it probably could increase the number of patients with induced chronic psychoses, especially those with greater susceptibility. One of the possible causes would be its analogous structure to other derivatives of phenylethylamine, which increase the risk of psychosis, and another would be the erroneous perception of being a less dangerous drug.

Functioning in acute inpatient psychiatric units has been challenged by the Coronavirus disease 2019 (COVID-19). Patients with more severe mental health symptoms changed their rates of voluntary admission to psychiatric wards during the onset of the pandemic. Peritraumatic distress scores and increased likelihood of being psychologically affected by the COVID-19 pandemic can lead to a psychiatric admission. However, other factors could prevent hospitalization.

The present investigation aimed at admission rates of patients by depression, adjustment disorder or suicidal behaviour to a General Hospital Psychiatric Ward. We compared the lockdown due to COVID-19 in 2020 to similar periods of 2018 and 2019.

The data of one general hospital psychiatric ward admissions have been obtained and analysed. We compared admission characteristics of 237 patients between April and June of 2018 and 2019 with 79 patients in the same period of 2020 (lockdown).

During the COVID-19 lockdown, there was a 35.8% reduction in psychiatric admissions and a significant reduction in psychiatric admission was observed due to suicidal behaviour (IRR = 0.49; 95% CI: 0.26-0.89; p=0.002) and depression (IRR = 0.24; 95% CI: 0.08-0.68; p=0.007), but similar rates of adjustment disorders (IRR = 1.12; 95% CI: 0.58-2.15; p=0.73).

We suggest that patients with depression or suicidal behaviour avoided admission, for fear of contagion in hospitals. Also, greater family support could prevent self-injurious behaviours. By contrast, other disorders continued to require the same admission rate, since the social consequences derived from confinement could lead to the genesis or worsening of symptoms, such as adjustment disorders.

Suicide rates in people diagnosed with a psychotic disorder can be up to 50 times higher than in the general population, with the lethality of attempts being significantly higher in this group, compared to people diagnosed with other psychiatric disorders. Furthermore, it is known that being male is associated with more serious suicide attempts and higher rates of completed suicides.

To reflect on the increased risk of suicide associated with psychotic disorders.

Case report and literature review.

Case report 40-year-old male, recently diagnosed with Schizophreniform Disorder and currently with persistent positive symptoms. He was admitted to our psychiatric hospitalization unit due to a voluntary overdose of almost 100 tablets (antihypertensives, antiarrhythmics, and benzodiazepines) and alcohol. He admits taking the pills with the aim of committing suicide. Literature review: - Around 10% of people diagnosed with schizophrenia commit suicide. - In young patients diagnosed with schizophrenia, suicide is the leading cause of death. - Between 15 and 65% of patients diagnosed with schizophrenia have depressive symptoms such as hopelessness. - Depressive symptoms in these patients seem to be directly proportionally with awareness of the disease (stigma, awareness of its severity and a sudden decrease in quality of life and social integration). - The risk of suicide increases especially in the first 10 years of the disease.

Psychosis is an important risk factor of suicide and active preventive measures should be carried out in these patients.
