BACKGROUND: There is a paucity of literature regarding the effect of antipsychotics on absolute neutrophil count (ANC) of patients with benign neutropenia (BN). We evaluated the change in ANC after atypical antipsychotic prescription (excluding clozapine) in a retrospective cohort of 22 patients with BN. METHODS/PROCEDURES: Records of all patients with BN who were prescribed antipsychotics and who had ANC measured before and during antipsychotic treatment were obtained from Bronx VA Medical Center between 2005 and 2015 (inclusive). Twenty-two patients met criteria for inclusion. Individual and group mean ANC were calculated before treatment and during treatment. A paired, two-tailed t test was performed on the group ANC means. RESULTS: The group mean pretreatment ANC was 1.24 +/- 0.220 K/cmm, and the mean ANC during the time of antipsychotic prescription increased to 1.40 +/- 0.230 K/cmm, with a P value of 0.0045, t value of 3.18, degrees of freedom equal to 21, and 95% confidence interval of 1.30 to 1.49 K/cmm. CONCLUSIONS: There was a statistically significant increase in ANC among our cohort during the time of antipsychotic prescription. All BN patients who were prescribed antipsychotics maintained a stable neutrophil count, with none of the 22 patients with BN in this study developing agranulocytosis during treatment. Although this study is limited by a low patient count as well as other demographic factors, these findings provide initial evidence regarding the safety of prescribing atypical antipsychotics to BN patients. Further studies are needed to replicate these findings and assess for effects of individual medications.

OBJECTIVES: Not all patients referred for evaluation of multiple sclerosis (MS) meet criteria required for MS or related entities. Identification of markers to exclude demyelinating disease may help detect patients whose presenting symptoms are inconsistent with MS. In this study, we evaluate whether patients who present a self-prepared list of symptoms during an initial visit are less likely to have demyelinating disease and whether this action, which we term the "list sign," may help exclude demyelinating disease. METHODS: Using chart review, 300 consecutive new patients who presented for evaluation to a neurologist at a tertiary MS referral center were identified retrospectively. Patients were defined as having demyelinating disease if diagnosed with MS or a related demyelinating condition. RESULTS: Of the 233 enrolled subjects, 157 were diagnosed with demyelinating disease and 74 did not meet criteria for demyelinating disease. Fifteen (8.4%) subjects had a positive list sign, of which 1 patient had demyelinating disease. The 15 subjects described a mean of 12.07 symptoms, and 8 of these patients met Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for somatic symptom disorder. The specificity and positive predictive value of the list sign for non-demyelinating disease were 0.99 (95% confidence interval (CI) 0.96-0.99) and 0.93 (95% CI 0.66-0.99), respectively. CONCLUSION: A positive list sign may be useful to exclude demyelinating disease and to guide diagnostic evaluations for other conditions. Patients with a positive list sign also have a high incidence of somatic symptom disorder.

We discuss the case of a patient with Progressive Multifocal Leukoencephalopathy (PML), developed after treatment with Natalizumab for 42 months for relapsing remitting multiple sclerosis (RRMS). Imaging was consistent with wide-spread PML with features that portended a high risk of development of Immune Reconstitution Inflammatory Syndrome (IRIS). After completion of plasmapheresis, she was started on oral maraviroc, chemokine receptor 5 antagonists. Our patient did not develop radiological signs or symptoms of clinical IRIS and tolerated maraviroc without adverse side-effects. We propose that maraviroc merits further examination as an agent that may prevent IRIS in patients with natalizumab-associated PML

We discuss the case of a patient with a known history of relapsing-remitting multiple sclerosis (MS) who presented with the isolated complaint of altered visual perception in the absence of abnormalities on ophthalmological examination. To the best of the authors' knowledge, this is the first documented case of both facial metamorphopsia and palinopsia occurring as the symptoms of demyelinating brain lesions consistent with an acute MS exacerbation. These symptoms appear to be related to active demyelination that either involved the optic radiations in the visual pathway or the visual association area in the temporo-occipital region of the left hemisphere.

OBJECTIVE: The authors surveyed Psychiatry Residency Training Directors' (RTDs') attitudes about the role and feasibility of international rotations during residency training. METHOD: A 21-question survey was electronically distributed that explored RTDs' beliefs about the value, use, and availability of international clinical and research experiences during residency. RESULTS: Of 171 RTDs, 59 (34.5%) completed the survey; 83% of respondents rated the importance of global mental health education as 3-or-above on a scale of 1 (least important) to 5 (most important), but only 42% indicated that such opportunities were made available. The value of such opportunities was thought to lie primarily in professional development and cultural exposure, less so for enhancing core knowledge competencies. Obstacles to such opportunities included lack of accreditation, financial resources, and faculty/administrative support and supervision. CONCLUSION: RTD respondents endorsed the value of international experiences during residency, but their availability and educational impact are not fully supported.

We discuss the case of a 35-year-old woman who presented with thought impoverishment, disorganized behavior, and echolalia. The patient's condition progressed to treatment-refractory catatonia. She was started on oral Coenzyme Q10 after magnetic resonance imaging of the brain showed findings consistent with drug-induced leukoencephalopathy (DIL). Following improvement, she acknowledged cocaine use that suggested a diagnosis of cocaine-induced leukoencephalopathy (CIL). This case report seeks to elucidate radiological and clinical features of DIL.

Not enough research has been carried out on depression up to now in Latin America. The knowledge that has resulted from research activities in the USA or Europe offers limited generalizability to other regions of the world, including Latin America. In the Andean highlands of Ecuador, we found very high rates of moderate and severe depressive symptoms, a finding that must be interpreted within its cultural context. Somatic manifestations of depression predominated over cognitive manifestations, and higher education level was protective against depression. These findings call for an appreciation of culturally specific manifestations of depression and the social factors that influence them. These factors must be further studied in order to give them the deserved priority, allocate resources appropriately, and formulate innovative psychosocial interventions.
