Finding a constrained number of predictor phenotypes for multiple outcome prediction.

Background: Prognostic models help aid medical decision-making. Various prognostic models are available via websites such as MDCalc, but these models typically predict one outcome, for example, stroke risk. Each model requires individual predictors, for example, age, lab results and comorbidities.

Managing blood requirement in a rare P-null phenotype patient during the COVID pandemic in a resource-limited setting.

We report the case of a 5-year-old girl with a rare P-null phenotype who presented for a neurosurgical procedure at our center. The case is unique as this patient was one of the two P-null phenotype cases reported in India and we report how we could successfully arrange a rare blood unit for her. As it was challenging to find a donor for her, autologous blood was collected.

Combined laparoscopic and gluteal approach for resection of a sciatic notch dumbbell lipoma.

The greater sciatic, lesser sciatic and obturator foramina are openings in the pelvis through which pelvic lesions can herniate, leading to the formation of rare dumbbell tumours. We present the case of a man in his late 60s, who presented with obstructed defecation. A per rectal examination revealed a palpable right sided rectal mass.
