Gastric ulcer perforation credited to paracoccidioidomycosis. Case report with autopsy / Úlcera gástrica perfurada por paracoccidioidomicose. Relato de caso com necropsia

Paracoccidioidomycosis or South American blastomycosis is an endemic disease that occurs predominantly in rural South America, caused by a termo-dimorphic fungus named Paracoccidioides brasiliensis. Its epidemiologic importance relates to its characteristics of transmissibility, susceptibility and morbidity, in addition to its high cost due to prolonged medical monitoring. It has a polymorfims in the description, explained by absent or nonspecific initial symptoms such as night sweats, weight loss or fever, and later symptoms according to its location of involvemente. The objective of this study was to report a case of uncommon presentation of this pathology. The case repot is the autopsy of a 74-year-old, white, female patient with predominant manifestation in the gastrointestinal tract originating from paracoccidioidomycosis, and complicated by one of the gastric ulcer perforation. This is an unusual presentation, and reports of gastric perforation credited to this agent were not found in the literature...

Paracoccidioidomicose ou blastomicose Sul Americana é uma enfermidade endêmica rural que ocorre predominantemente na América Latina, tendo como etiologia o fungo termodimórfico Paracoccidioides brasiliensis. Sua importância epidemiológica está nas características de transmissibilidade, suscetibilidade e morbidade dos casos, além de seu alto custo, devido ao acompanhamento médico prolongado. É uma doença cujos sintomas iniciais são ausentes ou inespecíficos como sudorese noturna, emagrecimento ou febre, diferente dos sintomas tardios, que acontecem conforme sua localização de acometimento, o que justifica o polimorfismo em sua descrição. O objetivo deste estudo foi relatar um caso de apresentação incomum dessa doença. Caso clínico com necrópsia de paciente do gênero feminino, 74 anos, branca, com manifestações clínicas predominantes no trato gastrintestinal provenientes de paracoccidioidomicose complicada pela perfuração de uma das úlceras gástricas. Trata-se de uma apresentação incomum e não foram encontrados relatos na literatura de perfuração de úlcera gástrica creditada a esse agente...

[Study of the CagA gene prevalence in helicobacter pylori strains isolated from patients with upper gastrointestinal disorders in Iran]

Helicobacter pylori commonly is associated with gastritis: but only sometimes it causes clinically significant diseases such as gastric and duodenal ulcer. The development of disease depends on the virulence of the infecting H. pylori strain, the susceptibility of the host, and environment co-factors. The cytotoxin associated protein encoded by cagA gene is an important virulence factor that is produced by some H. pylori strains, and has been used as virulence marker in some populations. The aim of the study was to examine the prevalence of cagA gene in the isolated strains of H. pylori from patients with dyspeptic disease and to investigate the association of cagA gene and the severity of H. pylori related diseases in Iran. In this study, biopsy specimens were obtained from the antrum of 180 patients. After isolation of H. pylori and its DNA by standard methods, polymerase chain reaction [PCR] technique was used for detection of cagA bacterial gene. 92 out of the 180 patients had H. pylori strains. 70% were cagA gene positive. All patients with peptic ulcer [100%] and 44 out of 72 [61%] patients with non-ulcer dyspepsia were cagA positive [p<0.01]. There was significant difference in frequency of cagA gene in peptic ulcer disease and non-ulcer dyspepsia [p<0.01]. It showed that the risk of PUD in patients with cagA+ H. pylori infection may be higher than in those with cagA- H. pylori infection

Disseminated strongyloidiasis: report of two fatal cases.

Strongyloides infection is usually asymptomatic but disseminated infection is a cause of morbidity and mortality in immunodeficient patients. Two fatal cases of strongyloidiasis are reported here, with rare manifestations of gastric ulcers with hematemesis and acute renal failure respectively.
