Glutathione (GSH) improves sperm quality and testicular morphology in streptozotocin-induced diabetic mice / 亚洲男科学杂志(英文版)

Diabetes mellitus (DM) is known to cause reproductive impairment. In men, it has been linked to altered sperm quality and testicular damage. Oxidative stress (OS) plays a pivotal role in the development of DM complications. Glutathione (GSH) is a part of a nonenzymatic antioxidant defense system that protects lipid, protein, and nucleic acids from oxidative damage. However, the protective effects of exogenous GSH on the male reproductive system have not been comprehensively examined. This study determined the impact of GSH supplementation in ameliorating the adverse effect of type 1 DM on sperm quality and the seminiferous tubules of diabetic C57BL/6NTac mice.

Pulmonary actinomycosis masquerading as aspergilloma

We report a case of a 34-year-old man who was initially treated as community acquired pneumonia following a three-month-history of productive cough, loss of weight and loss of appetite. However, three months after discharged from the hospital, he presented again with worsening respiratory symptoms and radiological evidence of a lung cavitation with intracavitary lesion resembling an aspergilloma associated with surrounding consolidation. Unfortunately, he remained symptomatic despite on antifungal therapy. The repeat computed-tomography demonstrated persistent cavitating lesion with development of necrotising pneumonia. He underwent lobectomy and the histopathological analysis of the resected specimen however revealed the diagnosis of actinomycosis. KEY WORDS: Actinomycosis, Aspergillosis

Atypical Clival Chordoma in an Adolescent without Imaging Evidence of Bone Involvement

Clival chordoma is a rare primary bone tumour that arises from the remnant of the notochord and typically occurs in older adults. Upon imaging, the tumour can be seen arising from the clivus and causes clival destruction. This usually provides insight for a diagnosis. Here we present a case of a non-enhancing, pre-pontine mass that was hypointense on T1W and hyperintense on T2W in an adolescent. No clival bone erosion was observed. Based on the age group, imaging findings, and lack of clival erosion, a provisional diagnosis of epidermoid cyst was made and the tumour was resected. This patient was eventually diagnosed with a clival chordoma based on histopathological examination.
