UNASSIGNED: Acute psychosis is a common brief psychiatric emergency period of delusions, hallucinations, disorganized thoughts and/or speech with or without psychomotor elements, which is not commonly induced by isotretinoin therapy. Dermatologists should counsel the patient before starting the treatment with all new, uncommon side effects, especially neuropsychiatric manifestations before starting this medication.
UNASSIGNED: A 23-year-old male smoker with a known case of acne vulgaris recently started on isotretinoin for 2 weeks after which he developed abnormal hyperactive psychomotor activity. He was diagnosed with isoteritoin-induced acute psychosis based on clinical findings and exclusion, and valproic acid and olanzapine were initiated. The patient showed significant improvement.
UNASSIGNED: Acute psychosis is a new, unfamiliar side effect presenting after initiation of isotretinoin therapy in young adults who were previously healthy. The mechanism is not well known but is thought to result from a decrease in the adult\'s neurogenesis or alterations in exposure of the serotonergic neurotransmitter system.
UNASSIGNED: Isotretinoin is commonly used nowadays for treating young adults. Patients and their families should be counselled about all the psychiatric side effects. Antipsychotics and antiepileptics with mood stabilizers may improve the acute status for patients with isotertoin-induced psychosis.

BACKGROUND: Baclofen is a γ -aminobutyric acid (GABA) agonist used to treat spasticity; however, it may be toxic at dosages above 200 mg. The psychological, nervous, cardiovascular, gastrointestinal, musculoskeletal, and respiratory systems are all affected. This report represents a case with the rare respiratory complications brought on by baclofen toxicity: atelectasis and pneumomediastinum.
METHODS: A 19-year-old female was admitted to the emergency department after attempting suicide by taking 20 baclofen tablets (500 mg). Imaging revealed pneumomediastinum, atelectasis, and a leftward displacement of mediastinal structures. Her therapy included a chest tube to relieve the pneumomediastinum and sodium valproate, promethazine, biperiden, and quetiapine for neurological symptoms. Four days after being admitted, she was successfully extubated without any complications.
CONCLUSIONS: Baclofen activates GABA-A and GABA-B receptors. High doses of baclofen may induce central nervous system and respiratory depression, requiring intensive care. GABA receptors may cause hallucinations, delusions, and agitation in baclofen overdose. High dosages of baclofen may cause bronchial and bronchiolar muscular spasms, leading to breathing problems and atelectasis. Recent animal studies on baclofen toxicity showed that increased alveolar pressure, circulatory abnormalities, edema, alveolar hemorrhages, and infiltration cause rupture and pneumomediastinum. Pneumomediastinum may need bed rest, oxygen, antitussives, and analgesics, but severe cases may necessitate a chest tube.
CONCLUSIONS: A high index of suspicion is required for early diagnosis of acute baclofen poisoning, which could manifest as respiratory complications, including pneumomediastinum and atelectasis. Since most cases are benign, it is still crucial for clinicians to detect complications early for further management.

Catatonia is defined by the Diagnostic and Statistical Manual of Mental Disorders-fifth Edition (DSM-5) as the presence of 3 or more of the following symptoms: catalepsy, waxy flexibility, stupor, agitation, mutism, negativism, posturing, mannerisms, stereotypies, grimacing, echolalia, and echopraxia. Screening instruments, such as the Bush Francis Catatonia Rating Scale (BFCRS) or the Northoff Catatonia Scale, are utilized to screen and track the severity and course of symptoms. The primary pharmacologic treatment for catatonia is the lorazepam challenge test. Second-line pharmacologic therapies are indicated when patients have an insufficient response to benzodiazepines and electroconvulsive therapy (ECT). In this case report, we report a case of a geriatric patient given high-dose zolpidem as an alternative agent with cardiac contraindications to ECT.

A 48-year-old patient with stable residual schizophrenia experienced a syndromic psychosis relapse following an episode of severe combined immunohemolytic and pure red cell aplastic anemia, with a hemoglobin level of 4.7 g/dl. The anemia was attributed to her anti-HIV medication zidovudine. Her HIV infection had been well-controlled; no other organic precipitant of the psychosis was found. Following transfusion of 2 units of leukocyte-poor packed red cells, schizophrenia symptoms promptly recovered to her baseline. This was maintained at 3- and 6-month follow-ups without any need for antipsychotic dose adjustment. Following zidovudine discontinuation and a short course of oral prednisolone, her anemia gradually recovered.

People with psychiatric disorders are one of the most vulnerable populations in disasters, and the 2011 Great East Japan Earthquake reported higher post-evacuation mortality rates among psychiatric inpatients. A psychiatric hospital evacuated after the nuclear accident was surveyed to gain valuable insights for future disaster preparedness.
The authors interviewed two Odaka Akasaka Hospital (a private psychiatric hospital) staff responsible for evacuation due to the nuclear accident.
At the time of the earthquake, 104 patients had been admitted to the hospital. They were instructed to evacuate on the grounds that they existed within a 20 km radius of Fukushima Daiichi Nuclear Power Station. Although the evacuation process was extraordinarily demanding, the staff acted professionally, and no patient experienced a significant deterioration in health during the evacuation.
It was reasonable to follow the evacuation order because of the difficulty of obtaining accurate information about radiation exposure and staff availability in high-risk situations. The staff\'s knowledgeable and attentive care of the patients was one of the factors that enabled them to successfully carry out this severe evacuation. However, this may be related to the high mortality rate after the evacuation of patients who were separated from such caregivers.

Vanishing white matter disease (VWMD) is the most common childhood-onset inheritable progressive leukodystrophy disorder, which exclusively affects the white matter of the brain. It shows mutations in one of the five eukaryotic translation initiation factor 2B1-5 genes following an autosomal recessive pattern, of which eIF2B5 mutation is the most frequent. These genes play a vital role in the translation and regulation of protein synthesis and mutation in them leads to a dysregulation of the cellular stress response, which in particular disrupts myelination and affects oligodendrocytes and astrocytes while sparing the neurons. Stressful situations, for example, head trauma, sudden fright, acute psychological stress, or infection, provoke severe and rapid neurological deterioration. Although it is more common in childhood, we report a case of an adult presenting with signs and symptoms of VWMD, such as abusive behavior, emotional liability, and motor incoordination. To our knowledge, this is the first case of adult-onset VWMD in Maharashtra, India, confirmed by magnetic resonance imaging (MRI) of the brain.

The COVID-19 pandemic that began in late 2019 is caused by infection with the severe acute respiratory syndrome coronavirus-2. Since that time, many neuropsychiatric sequelae including psychosis, neurocognitive disorders, and mood disorders have been observed. The mechanism underlying these effects are currently unknown, however several mechanisms have been proposed.
A 47-year-old woman with past medical history including hypertension and premenstrual syndrome but no psychiatric history presented to the psychiatric hospital with new onset mania. She had developed symptoms of COVID-19 and was later diagnosed with COVID pneumonia. During quarantine, she reported high levels of stress, grief, and anxiety. Seventeen days into her illness, she developed altered mental status, sleeplessness, elevated mood, talkativeness, and preoccupations. Her spouse was concerned for her safety and contacted emergency medical services who brought her to the psychiatric hospital. She had not slept for five days prior to her arrival and exhibited flight of ideas, talkativeness, and grandiose ideas. She reported a family history of bipolar disorder but no past manic or depressive episodes. She was diagnosed with acute mania and stabilized using antipsychotics, a mood stabilizer, and a short course of a benzodiazepine. Many of her symptoms improved, including her elevated mood, increased activity level, and flight of ideas though she continued to have decreased need for sleep as her benzodiazepine was tapered. She and her partner were agreeable to transitioning to outpatient care after her mood stabilized.
This report emphasizes the link between COVID-19 and neuropsychiatric symptoms. Acute mania has no recognized association with COVID-19, but similar presentations have been reported. The patient\'s age and time to onset of psychiatric symptoms is consistent with previous reports. Given the growing body of evidence, this association warrants further investigation. Severe acute respiratory syndrome coronavirus-2 causes systemic inflammation and has been shown to be neurotropic. In addition, patients undergoing quarantine experience anxiety related to the disease in addition to social isolation. Psychiatric practitioners should be aware of these effects and advocate for psychiatric evaluation following COVID-19 infection. Understanding the sequelae of infectious disease is crucial for responding to future pandemics.
