Abstract Objectives Neonatal severe hyperparathyroidism (NSHPT) is a rare condition characterized by inactivating mutations in the calcium-sensing receptor ( CaSR ) gene, leading to significant hypercalcemia and related complications. Case presentation We present case of six-day-old male infant with weakness, jaundice, hypotonia, later diagnosed NSHPT due known homozygous mutation (c.242T>A; p.I81K). Initial laboratory findings revealed markedly elevated serum calcium levels high...

Ectopic intrathyroidal thymus tissue that may be present as a thyroid nodule is rarely reported. We case of 4-year-old boy with solitary nodule. Real-time ultrasound showed calcified in the right lobe. Complete blood count, serum calcitonin, and thyroglobulin concentration were normal antithyroid antibodies negative. Fine-needle aspiration (FNA) biopsy was revealed inadequate for cytological examination. During his follow-up, nodular enlargement found, patient subjected to surgical total...

Abstract Severe ischemia or necrosis of glans penis is rare. We report the case an 11‐year‐old boy with severe glanular occurring 24 h after circumcision. This was successfully treated pentoxifylline injection for 5 days, and while black color changed to brownish at 48 h, appearances were close normal days. The patient did not require any surgical intervention, discharged without sequelae. suggest that might be considered as a treatment choice penis.

Considerable efforts have been made to find and/or eliminate the underyling causes of hepatic ischemia-reperfusion injury, but many points are still unclear. Pentoxifylline-related cytoprotection is one these unclear points. Our study tests effects pentoxifylline on cytoprotective process in an experimental model.The animals were divided into two groups: (1) placebo-pretreated rats and (2) pentoxifylline-pretreated rats. After pretreatment, all underwent procedure which was performed by...

Summary Background: We aimed to randomly compare intubating conditions, recovery characteristics and neuromuscular effects of single dose mivacurium (0.2 mg·kg −1 ) during sevoflurane vs. propofol anesthesia in 60 healthy children, undergoing inguinal surgery. Methods: All children were allocated receive 2 iv or 8% inspired concentration for induction anesthesia. Anaesthesia was maintained with 66% nitrous oxide oxygen 100–120 μ g·kg approximately 2–3% controlled ventilation. The ulnar nerve...
