Emergence of Indigenous Dengue Fever, Niger, October 2023.

Dengue fever is a growing worldwide public health concern. In mid-October 2023, multiple cases of uncommon febrile illness were reported among patients in Niamey, Niger. Fifteen samples were tested by using molecular methods, from which 7 (46.66%) were confirmed positive for mosquitoborne dengue virus belonging to serotypes 1 and 3.

First introduction of dengue virus type 3 in Niger, 2022.

Dengue fever is the most important mosquito-borne viral disease of humans, with a significant disease burden in tropical and subtropical countries. The disease is caused by four distinct dengue virus (DENV) serotypes, DENV-1 to -4, all of which belong to the family Flaviviridae, genus Flavivirus. Approximately 3.6 billion people live in areas where they are at risk of transmission of DENVs, resulting in up to 390 million infections and 96 million symptomatic cases annually. Although the disease is highly endemic in the West Africa region, little is known about the prevalence and distribution of DENVs in Niger. We hereby report the first laboratory-confirmed case of dengue in Niger.

Acute Abdomen Revealing an Unusual Case of Intra-Abdominal Testicular Torsion.

Introduction. Intra-abdominal testicular torsion is a rare event. We report hereby our experience of the management of a spermatic cord twist on intra-abdominal testis discovered during an acute surgical abdomen. Case Presentation. This was a 42-year-old patient admitted to the emergency department for abdominal pain that had been evolving for a week. The physical examination showed tenderness and guarding in the left iliac fossa with an empty ipsilateral hemiscrotum. Complementary examinations led to the discovery of an intra-abdominal left-lateral mass. The laparotomy found a whitish mass with areas of infarction, which was resected. Anatomopathological examination of the operative specimen identified it as a testis with atrophy of germ cells and necrotic areas without evidence of malignancy. Conclusion. Intra-abdominal testicular torsion should be considered in case of patients with an acute surgical abdomen with vacuity of one of the bursae.
