[The use of venous catheter : Which ones to choose, how to prevent their complications?]

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.

[Diagnostic issues of lymphogranuloma venereum: A case series of 5 patients]

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.
