Routine preoperative Doppler screening of the radial artery in the setting of limited resources is not justified. On the other hand, the time-tested Allen test which is easy to perform, interpret, and reproduce can be safely used as the sole screening test to harvest the radial artery.

Umbilical endometriosis is a type of cutaneous endometriosis that usually follows laparoscopic or surgical procedures that involve the umbilicus. Primary umbilical endometriosis (PUE) is an extremely rare condition and its association with an umbilical hernia is an equally rare condition. To date, only very few cases of PUE with umbilical hernia association have been reported in the medical literature. Report herein is a case of PUE associated with an umbilical hernia who presented with classical umbilical nodule symptoms with cyclical pain and bleeding due to menstruation. The patient underwent omphalectomy with abdominal wall defect repair using prosthetic mesh. The diagnosis was confirmed by histopathological examination of the excised umbilical nodule. This case report highlights a rare entity that should be considered as a differential diagnosis in females of the reproductive age group that presents with the umbilical nodule.

Formalin is a protoplasmic poison, which poses a potential occupational hazard among morticians, embalmers, pathologists, and hospital staff. The crystal-clear appearance of formalin can be easily mistaken for normal saline, local anesthetics, hydrogen peroxide, sodium hypochlorite, and spirit in health care facilities and water in domestic settings. However, accidental poisoning is extremely rare because of its low olfactory threshold, strong irritant nature, pungent taste, and odor. This is also evident from the scarce scientific literature on this topic. Here, we presented a case of accidental, fatal formalin ingestion by a 4-year-old child who succumbed to the poisoning within 12 h of ingestion. The case presented here is unique because of its rarity in causing accidental poisoning by ingestion and first of its kind in a child.
