Survival Estimates and Mortality Risk Factors in a Cohort of HIV Vertically Infected Individuals in Salvador, Brazil.

BACKGROUND: There are few data on long-term survival of Brazilian children with vertically acquired HIV infection. We assessed survival, mortality risk factors and response to antiretroviral therapy (ART). We compared children with early and late access to care. METHODS: We used Kaplan-Meier survival curves with Log-rank tests to compare survival time and mortality rates of 245 HIV vertically infected children admitted for care during 2002-2014. RESULTS: Total follow-up sum was 1584.4 person-years. Overall survival was 83.9%. Median age at start of ART was 51.6 (18.0-94.2) months, and median age at death was 8.2 (1.7-10.1) years (mortality rate: 1.7/100 person-years). Pneumonia and sepsis were the main causes of death. Male gender, viral load (VL) ≥100,000 copies, severe immunosuppression, moderate/severe symptoms and history of opportunistic infection were associated with higher mortality in bivariate analysis. Only severe symptoms remained associated in multivariate analysis (P = 0.03). There was no difference in mortality in early compared to late access group. Overall, 217 patients received ART; 192 had a recent VL, of which 116 (59.8%) had ≤400 copies. Variables associated with therapeutic failure were as follows: VL ≥100,000 copies, less immune suppression, age <12 months at admission and age <3 years at ART start. CONCLUSIONS: We have a high mortality rate in comparison with developed countries. Although early access did not impact mortality, we detected a trend in favor of early treatment as a protecting factor against mortality. We need to increase adherence to care and treatment, and better drugs to optimize outcomes.

Primary cutaneous marginal zone lymphoma with subclinical cutaneous involvement and biclonality.

Primary cutaneous extranodal marginal zone lymphoma (MZL) of mucosa-associated lymphoid tissue (MALT) represents a monoclonal B-cell neoplasm that typically presents with papules, plaques or nodules. We describe a patient with a primary cutaneous MALT lymphoma with unusual clinical features and an unusual immunophenotype. Conventional microscopy together with immunohistochemistry and in-situ hybridization showed the presence of lymphoma in normal-appearing and minimally erythematous skin as well as in clinically involved skin. Furthermore, at least two distinct clones were shown, one of which had κ-light chain restriction, and the other of which had λ-light chain restriction. This case represents a newly described clinical appearance of primary cutaneous MZL and shows that some patients may have more than one neoplastic clone.

Phlegmonous gastritis in a patient with myeloid sarcoma: a case report.

Phlegmonous gastritis is a rare acute bacterial infection of the gastric wall with an extremely high mortality rate. Early diagnosis is crucial for immediate treatment that could improve the outcomes. Here we report a case in which a patient with underlying chronic myelomonocytic leukemia was diagnosed with phlegmonous gastritis on biopsy. This 57-year-old man presented with shortness of breath and intermittent upper quadrant abdominal pain for 4 days. Laboratory tests showed markedly increased white blood cell. A diagnosis of chronic myelomonocytic leukemia was made based on a peripheral blood smear and flow cytometry. Gastric biopsy showed suppurative inflammation in the submucosal region, prompting the diagnosis of phlegmonous gastritis. The patient was given empirical antibiotic treatment, and the white blood cell decreased dramatically. Surgical intervention was discussed but deferred. Despite continued antibiotics treatment, the patient died. The limited autopsy confirmed the diagnosis of phlegmonous gastritis. Immunohistochemical studies further revealed the occurrence of myeloid sarcoma that involved the gastrointestinal tract.

Pimozide in dermatologic practice: a comprehensive review.

Pimozide is an antipsychotic drug of the diphenylbutylpiperidine class. In the US, it is FDA-approved only as a backup treatment for Gilles de la Tourette syndrome, although it has been used in other countries for many years as a treatment for schizophrenia. In the past 20 years, pimozide has been found to be especially efficacious in the treatment of monosymptomatic hypochondriacal psychoses and is used by psychiatrists and dermatologists for this off-label purpose. In particular, pimozide is considered the treatment of choice for delusions of parasitosis. In addition, pimozide has been found to be efficacious in the treatment of body dysmorphic disorder, metastatic melanoma, trichotillomania, and trigeminal and postherpetic neuralgia. This review aims to familiarize physicians, especially dermatologists, on the uses of pimozide in dermatologic practice. A review of the literature was performed and the relevant information synthesized to give a complete overview of the drug and its therapeutic uses in dermatology.
