We report the presentation and management of a case of 3 month age infant who had scrotal swelling primarily diagnosed as hydrocele.

Cerebral venous sinus thrombosis in COVID 19 patients: Report of 2 cases.

Background: Initially, novel severe acute respiratory syndrome coronavirus (SARS-CoV-2) was considered primarily a respiratory pathogen. However, with time it has behaved as a virus with the potential to cause multi-system involvement, including neurological manifestations which varies from acute to subacute onset of headache, seizures, a decrease of consciousness, and paralysis.

Case Description: Two cases of cerebral sinus venous thrombosis in COVID-19 patients were reported, following respiratory disorders, which was triggered by the SARS-CoV-2 infection.

Cerebral venous sinus thrombosis in patients with COVID-19 infection.

Background: Despite the COVID-19 infection is more frequently related to acute respiratory distress but there is an increasing evidence of a heterogeneous spectrum of multi-system involvement including the central nervous system. Thromboembolic events after COVID-19 infection have been reported mainly in the pulmonary vasculature however; thromboembolic complications of the nervous system with subsequent cerebrovascular stroke have been increasingly reported. The most common cerebrovascular complication after COVID-19 infection is ischemic stroke however there is also reported cases of cerebral venous sinus thrombosis in such patients as well.

Case Description: Here, we report a 41-year-old male, diagnosed with SCEH, with a presenting chief complaint of cervical pain followed by progressive quadriparesis and urgency of micturition who was managed surgically, along with the review of literature.

Ossified Spinal Meningioma: A Case Report and a Review of the Literature.

Ossified spinal meningiomas are a rare form of spinal tumors. These tumors increase surgical morbidities due to their hard consistency and strong adhesion to the neural tissue and relatively narrow surgical space. Here, the authors describe the clinical findings, surgical strategies, and histological findings of a patient with an ossified meningioma.

Cranial migration of lumboperitoneal shunt: A case report and review of literature.

Background: Lumboperitoneal shunt is an easy and effective way of managing benign intracranial hypertension (BIH) and other causes of increased intracranial pressure. Yet, it is associated with a relative high failure rate. Proximal migration of the shunt is rare and only few cases have been reported.

Onychomycosis: Correlation between the dermoscopic patterns and fungal culture.

Background: Onychomycosis is a dermatophyte fungal infection of the nail plate, bed, and the matrix, leading to the gradual damage which often considered a cosmetic problem. Several presentations of onychomycosis: distolateral subungual (DLSOM), superficial white, proximal subungual, endonyx, and total dystrophic (TDOM). Although the diagnosis relies on mycological results, there are three specific dermoscopic findings for onychomycosis: a jagged edge of the onycholytic area, with spikes directed to the proximal fold, white-yellow longitudinal striae in the onycholytic nail plate, and colored parallel bands.

Olfactory Nerve Schwannoma: A Case Report and Review of the Literature.

Schwannomas are benign tumors, which arise from the Schwann cells of the central or peripheral nerves. They form 8% of all intracranial tumors and most of the cases arise from vestibular division of the 8 cranial nerve. Rare cases are shown to arise from the olfactory or optic nerve, being devoid of myelin sheath.

Association between δ-aminolevulinate dehydratase G177C polymorphism and blood lead levels in brain tumor patients.

As the δ-aminolevulinic acid dehydratase () G177C polymorphism affects the toxicokinetics of lead in the body, and the corresponding exposure to lead may increase the risk of adult brain tumors, we hypothesize that there is a possible association of the G177C genotype and the risk of brain tumors in human. Therefore, the aim of the present study was to clarify the role of the ALAD enzyme gene polymorphism at position G177C in the pathogenesis of brain tumors and its correlation to lead exposure. The gene polymorphism at position G177C was genotyped using the polymerase chain reaction with restriction fragment length polymorphism method and measured the blood lead level by atomic absorption in 81 brain tumor patients and compared the results with 81 controls.
