To monitor the oviposition activity of the mosquito Aedes aegypti and of dengue and chikungunya cases in four localities of temperate Argentina, during the 2023 epidemic. ⋯ It is essential to raise awareness and train the members of the health systems of the new regions exposed to Ae. aegypti for early detection of cases, and to the general population to enhance prevention actions.

Melanotic schwannoma (MS) is a rare and infrequent subtype of schwannoma characterized by cytoplasmic deposits of melanosomes (melanin). Unlike the other schwannomas, it could have malignant transformation. Due to distinctive characteristics and atypical behavior from classic schwannomas subtypes, MS were renamed and reclassified as "melanocytic malignant neural sheath tumor" in the 5th ed. of the World Health Organization's classification of central nervous system tumors in 2021. We present two cases of MS that underwent complete surgical resection.

[Multiple endocrine neoplasia and very early onset inflammatory bowel disease. An unexpected association].
Very early onset inflammatory bowel disease (VEOIBD) is a rare entity in pediatrics. Its association with primary immunodeficiencies of monogenic origin is known. ⋯ There are no previous reports of association of RET proto-oncogene variants with VEOIBD. The presence of these two clinical entities cannot be attributed to a single genetic cause.

Enteral nutrition through jejunostomy is a common practice in any general surgery service; it carries a low risk of complications and morbidity and mortality. We present the case of a patient with an immediate history of subtotal gastrectomy that began nutrition through jejunostomy and complicated with intestinal necrosis due to non-occlusive ischemia in the short period. The purpose of this work is to report on this complication, its pathophysiology and risk factors to take it into account and be able to take appropriate therapeutic action early.

Chikungunya virus is an Alphavirus, it belongs to the family Togaviridae and is transmitted by mosquitoes. It was first described during an outbreak in Southern Tanzania in 1952. It generally causes a febrile syndrome, accompanied by joint pain and arthritis, which is often debilitating and may persist for months or years. ⋯ A report of detectable Chikungunya virus by real-time polymerase chain reaction in real time was received post-mortem. This case results of clinical relevance due to its atypical presentation and the country low prevalence of severe infections by this virus. It warns of the need to include the differential diagnosis in cases with suspected diagnosis.
