RESUMO

Intravenous catheters are multiple and essential for daily practice. They are also responsible for high morbidity and mortality. Simple or echo-guided peripheral venous catheters, midlines, PICCline, tunneled or non-tunneled central venous catheters, and implantable venous access device are currently at our disposal. Thus, catheter selection, duration and indications for use, and prevention and treatment of complications vary according to the situation. The objective of this update is to provide the clinician with an overview of knowledge and rules of good practice on the use of catheters.

RESUMO

INTRODUCTION: Lymphogranuloma venereum (LG) is a sexually transmitted infection (STI) caused by Chlamydia trachomatis L serovar. METHODS: These five consecutive cases aim to highlight the risk of LG misdiagnosis, in case of initial presentation with isolated inguinal adenitis. RESULTS: Five men (mean age: 30±7 years) were seen in an internal medicine department, for inguinal adenopathy. One patient had clinical signs of urethritis. None presented an associated rectitis. Three patients had a history of STI, and two had a discovery of related HIV disease. Urinary polymerase chain reaction (PCR) was positive for the symptomatic patient and negative for the others. Lymph node PCR was positive in all patients within a L2b serotype (searched in 4 out of 5 cases). CONCLUSION: LG should be evoked in any patient with inguinal adenomegaly, particularly in case of STI history or risk factors. Negativity of urinary PCR should lead to further investigations, essentially a lymph node cytopuncture to evidence C. trachomatis.

RESUMO

Myeloproliferative neoplasms (MPNs, formerly called chronic myeloproliferative disorders) are clonal hematopoietic stem cell disorders characterized by the expansion of one or more of the myeloid lineages, including polymorphonuclear, erythroid, megakaryocytic, and mastocytic. The major complications of MPN are transformation into acute myeloid leukemia (occurring particularly in chronic myelogenous leukemia) and thrombotic and hemorrhagic events (most commonly observed in polycythemia vera and essential thrombocythemia). Renal involvement by MPN is infrequent. MPN-related glomerulopathy enlarges the spectrum of glomerular diseases associated with haematological neoplasms. MPN-related glomerulopathy is an under recognized late renal complication of MPN with poor prognosis. It is characterized clinically by heavy proteinuria and renal insufficiency. The histologic features of MPN-related glomerulopathy include variable degree of mesangial sclerosis and hypercellularity, segmental sclerosis, features of chronic thrombotic microangiopathy, and intracapillary hematopoietic cell infiltration. PDGF and TGFß likely have a crucial role in the pathogenesis of MPN-related glomerulopathy. Furthermore, aggregation of circulating hematopoietic cells within glomerular capillaries could potentially result in endothelial injury and morphologic changes resembling chronic thrombotic microangiopathy. Greater awareness of this entity is needed to define diagnosis and possible therapies.
