Reservoir displacement by an invasive rodent reduces Lassa virus zoonotic spillover risk.

The black rat (Rattus rattus) is a globally invasive species that has been widely introduced across Africa. Within its invasive range in West Africa, R. rattus may compete with the native rodent Mastomys natalensis, the primary reservoir host of Lassa virus, a zoonotic pathogen that kills thousands annually.

Chronic Subdural Hematoma: Predicting Postoperative Recurrence Using a Correlation of Computerized Tomographic Volume with Intraoperative Volume.

Background: Chronic subdural hematoma (CSDH) recurrence is the most common complication following surgery.

Objective: To predict postoperative recurrence of CSDH using a correlation of the calculated preoperative brain computerized tomographic (CT) volume with the intraoperative volume.

Materials And Methods: A prospective study was conducted over 14 months in a tertiary hospital in southwestern Nigeria.

Female monozygotic twins with sacral myelomeningocele.

Background: Concurrent myelomeningocele in twins is a rare clinical presentation, only reported twice in Nigeria.

Case Description: We present a set of identical female twins from Nigeria. Both twins were females that presented at 3 years with low back swelling since birth, associated with bisphincteric dysfunction but normal motor and sensory functions in the lower extremities.

Clinical and microbiological profile of otomycosis in Lagos, Nigeria.

Introduction: Otomycosis is a global disease, common in the world's tropical and subtropical regions. The diagnosis is clinical, but mycological examination is required for its confirmation. There is a paucity of published data on otomycosis particularly the aetiologic agents in Nigeria.

Identifying the genetic basis of viral spillover using Lassa virus as a test case.

The rate at which zoonotic viruses spill over into the human population varies significantly over space and time. Remarkably, we do not yet know how much of this variation is attributable to genetic variation within viral populations. This gap in understanding arises because we lack methods of genetic analysis that can be easily applied to zoonotic viruses, where the number of available viral sequences is often limited, and opportunistic sampling introduces significant population stratification.
