Acute intoxication with verapamil.

A healthy 18-year-old man was admitted to our unit two hours after a suicidal ingestion of 2 gm of verapamil. There was mild hypotension, depression of the sinus node, atrioventricular dissociation, changes of repolarization, and first-degree intranodal atrioventricular block (the His bundle electrogram revealed an atrio-His [A-H] interval of 155 msec). Twenty-four hours after ingestion, the patient was well, and the electrocardiogram was completely normal. This case gave us a good opporturnity to study the electrocardiologic effects of a huge oral dose of verapamil on a healthy young heart.

Incidence of pneumothorax and pneumomediastinum in patients with aspiration pneumonia requiring ventilatory support.

In a prospective study of patients with ventilatory support, six (38 percent) of 16 patients who had ventilatory support because of aspiration pneumonia developed pneumothorax and pneumomediastinum. In contrast, the incidence of barotrauma in the entire group of patients who had ventilatory support during a year was 4 percent (22/553) (P less than 0.001). This greater incidence in the group with aspiration pneumonia was also observed when patients who were receiving ventilatory support with positive end-expiratory pressure were excluded.

Behçet's disease and hereditary periodic fever syndromes: casual association or causal relationship?

OBJECTIVE: Mutations in the MEFV and the type 1 TNF receptor (TNFRSF 1A) genes have recently been linked to familial Mediterranean fever (FMF) and TNF receptor-associated periodic syndrome (TRAPS), respectively. A higher prevalence of Behçet's disease (BD) among FMF patients has been described compared to the general population. The aim of this study was to evaluate whether FMF TRAPS and BD could be genetically related. METHODS: We screened a cohort of 50 BD patients and 100 healthy subjects for the common MEFV and TNFRSF 1A mutations. An initial screening of exons 10 and 2 of the MEFV gene and exon 4 of the TNFRSF 1A was performed in all chromosomes. RESULTS: The heterozygous MEFV mutation (K695R) was found in one (2%) BD patient. Analysis for FMF mutations in the control group revealed that 5 (5%) individuals bore MEFV gene mutations (3 were heterozygous for the E148Q and 2 were heterozygous for the A744S). At codon 202, there were no differences in allele frequencies between BD and control population: 73%R 27%Q in the BD patients vs 75%R 25%Q in controls. Concerning mutations in the TNFRSF 1A gene, the R92Q mutation was present in heterozygous state in one (2%) BD patient and in 4 (4%) controls without differences between allele frequencies: 99%R 1%Q in BD patients vs 98%R 2%Q in controls, respectively. There was no association between the clinical manifestations of BD patients and the presence of a particular polymorphism or a mutation. CONCLUSIONS: Neither FMF nor TRAPS are genetically associated with BD in our cohort of Spanish patients.

[Anorectal diseases in patients with human immunodeficiency virus (HIV) infection].

BACKGROUND: The incidence of VIH-related disease has arisen dramatically in the last decade. Many of these patients will present with specific anorectal complaints. PURPOSE: This review paper was performed to discuss the diagnostic and therapeutic implications of anorectal diseases in patients with VIH infection. RESULTS: A detailed sexual history is important in order to document the mode of transmission. The nature of the anorectal complaint is then evaluated and classified as infectious, neoplastic or idiopathic. Treatment should be planned accordingly. CONCLUSIONS: In the 1990's it's important that the physician who cares for patients with anorectal complaints be familiar with VIH-related diseases and their treatment plans.
