Gitelman Syndrome: Three Cases of a Rare Genetic Disorder in a Tertiary Care Hospital

Abtahir Rahim Taha, Hossain Shahbaz, Rahim Abdur, Rafiqul Islam

Gitelman syndrome is a salt-losing tubulopathy caused by mutation of genes encoding sodium chloride (NCCT) and magnesium transporters in the thiazide-sensitive segments of the distal nephron. It is characterized by renal potassium wasting, hypokalemia, metabolic alkalosis, hypocalciuria and hypomagnesemia. Here we present …

Three cases of hypopituitarism with variable presentation

M.Tojammal Hossain ., Haque Ahasanul, Afrozrafiya, Bashar Fuad Bin et autres

Patients with hypopituitarism often experience a delay in diagnosis. Symptoms which maybe life threatening are nonspecific and often attributed to aging and/or related morbidities. We have diagnosed three patients with hypopituitarism. We treated them accordingly and they dramatically improved. Our first case …

Selective Spin Dewetting for Perovskite Solar Modules Fabricated on Engineered Au/ITO Substrates

Son Pal Singh, Rahim Abdur, Md Abdul Kuddus Sheikh, Bhabani Sankar Swain et autres

We introduce a novel method for fabricating perovskite solar modules using selective spin-coating on various Au/ITO patterned substrates. These patterns were engineered for two purposes: (1) to enhance selectivity of monolayers primarily self-assembling on the Au electrode, and (2) to enable seamless …
