Interstitial granulomatous dermatitis and concurrent immunotherapy associated encephalitis with nivolumab and ipilimumab.

Immune-related adverse events (irAEs) are common in patients receiving immune checkpoint inhibitors for metastatic melanoma and other advanced malignancies. Cutaneous, gastrointestinal, and endocrine (thyroid) irAEs are most prevalent, whereas neurologic irAEs are rare. We present a 73-year-old man with dementia and metastatic melanoma who developed immunotherapy-associated encephalitis and subsequently, interstitial granulomatous dermatitis with nivolumab/ipilimumab. High-dose corticosteroids successfully treated both conditions, though he never regained his baseline mental status. We review the literature on interstitial granulomatous dermatitis and encephalitis with immunotherapy.

Comparative effectiveness of home blood pressure telemonitoring (HBPTM) plus nurse case management versus HBPTM alone among Black and Hispanic stroke survivors: study protocol for a randomized controlled trial.

BACKGROUND: Black and Hispanic stroke survivors experience higher rates of recurrent stroke than whites. This disparity is partly explained by disproportionately higher rates of uncontrolled hypertension in these populations. Home blood pressure telemonitoring (HBPTM) and nurse case management (NCM) have proven efficacy in addressing the multilevel barriers to blood pressure (BP) control and reducing BP. However, the effectiveness of these interventions has not been evaluated in stroke patients. This study is designed to evaluate the comparative effectiveness, cost-effectiveness and sustainability of these two telehealth interventions in reducing BP and recurrent stroke among high-risk Black and Hispanic stroke survivors with uncontrolled hypertension. METHODS/DESIGN: A total of 450 Black and Hispanic patients with recent nondisabling stroke and uncontrolled hypertension are randomly assigned to one of two 12-month interventions: 1) HBPTM with wireless feedback to primary care providers or 2) HBPTM plus individualized, culturally-tailored, telephone-based NCM. Patients are recruited from stroke centers and primary care practices within the Health and Hospital Corporations (HHC) Network in New York City. Study visits occur at baseline, 6, 12 and 24 months. The primary outcomes are within-patient change in systolic BP at 12 months, and the rate of stroke recurrence at 24 months. The secondary outcome is the comparative cost-effectiveness of the interventions at 12 and 24 months; and exploratory outcomes include changes in stroke risk factors, health behaviors and treatment intensification. Recruitment for the stroke telemonitoring hypertension trial is currently ongoing. DISCUSSION: The combination of two established and effective interventions along with the utilization of health information technology supports the sustainability of the HBPTM + NCM intervention and feasibility of its widespread implementation. Results of this trial will provide strong empirical evidence to inform clinical guidelines for management of stroke in minority stroke survivors with uncontrolled hypertension. If effective among Black and Hispanic stroke survivors, these interventions have the potential to substantially mitigate racial and ethnic disparities in stroke recurrence.

Postbariatric surgery neuropathic pain (PBSNP): case report, literature review, and treatment options.

OBJECTIVE: This study is aimed at facilitating clinician understanding of factors associated with postbariatric surgery neuropathic pain (PBSNP) and discussing the evidence base for management options. DESIGN: A case report and systematic literature review. METHODS: A search was conducted of PubMed, MEDLINE, Google Scholar, EMBASE, Psych Info, and Cochrane Database of Reviews for articles published between 1985 and 2013 on neuropathy, pain, and pharmacokinetics associated with postbariatric surgery. RESULTS: The epidemiology of PBSNP has not been well established, and current therapeutic options are not evidence based. Available data indicate up to 33% incidence of pain in patients with neuropathy after bariatric surgery, resulting in significant decreases in quality of life and increases in health care costs. Pathophysiologic mechanisms underlying PBSNP are unclear, and the natural course is variable, with some patients experiencing spontaneous improvement when nutritional deficiency is identified and corrected. Early identification of nutritional deficiency along with glycemic and lipid control may prevent or partially reverse postsurgical neuropathy and modulate PBSNP. CONCLUSIONS: A better understanding of the peripheral and central mechanisms resulting in PBSNP is likely to promote the development of targeted and effective treatments.

Confounding psychosis in the postpartum period.

This case report alerts the psychiatric clinician to consider nonpsychiatric etiologies of psychosis appearing during the postpartum period besides postpartum psychosis. The case includes a description of the patient's psychiatric presentation, admission to the inpatient psychiatric unit with subsequent transfer to the medicine department including neuroimaging and neurological consultation. The patient had a remission of psychosis after only two and half days of antipsychotic medication administration. Positive findings on the MRI suggested a demyelinating disease and a 4-month follow up MRI continued to be positive. The etiology was presumed to be a demyelinating disease. In conclusion, psychiatrists need to be alert to include nonpsychiatric pathologies in the differential diagnosis when a patient presents with psychosis in the postpartum period.

Multiple sclerosis and Epstein-Barr virus: a growing association.

The etiology of multiple sclerosis is an elusive field due to the lack of the usual cause-effect relationship model to explain a disease. In fact, with all the current evidence we start thinking in multiple sclerosis as a multi-factorial disease, where an infective agent on a genetically permissive host can lead to inflammation, demyelination and ultimately to neurological damage with dire consequences for the patients. This review will focus on the role of viruses in multiple sclerosis etiology and give some insight regarding this complicated issue.
