Severe anorexia nervosa in a 20-year-old male with pericardial effusion and cortical atrophy.

This case report describes a 20-year-old man with a severe presentation of anorexia nervosa. His case is unique in that he presented at 49% of his ideal body weight and had a body mass index (BMI) of 11.59. In addition, he had cognitive slowing on exam and had cortical atrophy on a head CT. Other medical complications included pericardial tamponade that was treated with an open window pericardiocentesis, hepatitis, and anemia. He was treated nutritionally, first with a Dobb-Hoff tube and then with oral feedings, as well as had group, individual, and family therapies. He responded well to treatment, his labs normalized and he was discharged at 75% of his ideal body weight after a weight increase of 40 pounds and after 106 days of hospitalization at our facility. In addition, a head CT was repeated and the cortical atrophy had resolved.

Treatment of refractory substance-induced psychosis in adolescent males with a genetic predisposition to mental illness.

This article presents two cases of adolescent males who were admitted to our inpatient psychiatric unit with a psychotic, disorganized presentation. Both males had a genetic vulnerability to mental illness and reported significant substance use. Their symptoms were refractory to treatment and required the use of clozapine. Both patients experienced significant side effects, which limited the maximum daily dose of clozapine. However, they responded to a dose that was much lower than that typically used in adults. There is significant evidence in the literature about cannabis use triggering psychotic breaks in vulnerable individuals. We speculate that substance use (including synthetic cannabinoids) triggers treatment-resistant psychosis that requires the use of clozapine. Further, lower doses of clozapine may be sufficient to treat the substance-induced psychotic symptoms than those typically used in adult schizophrenia.

Zonisamide for weight loss in adolescents.

Obesity in children and adolescents is a growing epidemic in the United States, and physicians are increasingly looking for safe and effective treatments. In recent years, pharmacologic treatment has been considered for severe and refractory cases of adolescent obesity. We present a case of an obese adolescent who presented to an inpatient psychiatric unit with a body mass index (BMI) of 37.8 (>98th percentile for age). He was started on zonisamide for the purposes of weight loss, and a steady decrease in weight and BMI was noted through 4 months of outpatient follow-up. During this time, the patient's weight decreased from 126.8 kg to 106.2 kg, a 20.6-kg loss, representing a 16.25% reduction in weight. His most recent BMI decreased to 31.7 (96th percentile for age). We discuss the potential use of zonisamide for weight loss in adolescents, considering the potential risks and benefits.

A case of severe adolescent obsessive-compulsive disorder treated with inpatient hospitalization, risperidone and sertraline.

BACKGROUND: The initial treatment of obsessive-compulsive disorder (OCD) has generally been limited to serotonergic agents, cognitive-behavioral therapy (CBT), or a combination of the two. These findings were supported by the POTS study for OCD in children and adolescents. However, treatment with serotonergic agents or CBT can take several weeks before benefit is seen; severe cases of OCD may require more immediate treatment. CASE REPORT: The authors present a case of severe OCD in an adolescent that required immediate treatment due to her critical medical condition. The patient's symptoms included not eating or taking medications or fluids by mouth due to fears of contamination. A medical hospitalization was previously required due to dehydration. As treatment with an SSRI would not have quick enough onset and the patient was initially resistant to participating in CBT, the patient was psychiatrically hospitalized and first started on liquid risperidone. After several doses of risperidone, the patient was able to participate in CBT and start sertraline. DISCUSSION: The authors discuss the differential diagnosis of such a patient, including the continuum of OCD symptoms and psychotic symptoms. The authors discuss the different treatment options, including the utilization of inpatient psychiatric hospitalization. The authors discuss the potential risks and benefits of using atypical antipsychotics in lieu of benzodiazepines for the initial treatment of severe adolescent OCD. The authors also discuss other current treatment recommendations and rationale for the treatment that was pursued. CONCLUSIONS: This patient received benefit of her symptoms relatively quickly with psychiatric hospitalization and an atypical antipsychotic. The diagnosis of a psychotic disorder should be considered. These treatment options must be weighed against the risks of atypical antipsychotics, including extrapyramidal symptoms, weight gain, and metabolic syndrome; benzodiazepines also have their risks and benefits. Additionally, the cost of time and finances of inpatient hospitalization must be considered. More research is needed regarding the short- and long-term efficacy and safety of antipsychotics in the treatment of OCD in the child and adolescent population.

When non-epileptic seizures fool the experts.

Even when non-epileptic seizures are correctly diagnosed, appropriate treatment recommendations may not be fully or correctly implemented. We present a case of a 17-year-old girl with frequent non-epileptic seizures who presented for frequent trips to the emergency room (ER) and was admitted to an inpatient Child and Adolescent Psychiatric Facility. Despite being informed that episodes were non-epileptic seizures, various staff and healthcare providers at the psychiatric hospital continued to send the patient to the ER to treat suspected epileptic seizures. We discuss possible reasons why this may have occurred, including psychosocial and emotional reactions of staff members to the episodes. This discussion may also help to explain the persistence of the patient's episodes. We also present options for minimizing the potential for future mismanagement of non-epileptic seizures.

Psychosocial stress and abdominal pain in adolescents.

Children and adolescents may express psychiatric symptoms via somatic complaints. Likewise, children with chronic somatic illnesses are likely to experience psychiatric sequelae. We report three cases of adolescents who were admitted to general paediatrics services for abdominal pain and/or nausea and vomiting with a negative medical workup. In each case, a clear psychosocial stressor was evident. It is possible that somatic symptoms without clear medical causes may reflect psychosocial stress, but it is difficult to discern whether the psychosocial issues preceded the somatic complaints or were a result of them. Making an accurate diagnosis is difficult, and broaching such a subject with patients and their families is a delicate matter. More research is needed to determine appropriate screening tools for identifying cases where psychosocial stress may play a relevant role in symptom presentation, as well as potential treatment modalities for such cases.
