Isolated fallopian tube torsion with hydrosalpinx in a 14 year old girl: A case report.
Int J Surg Case Rep
January 2025
Ranga Hospital, Coimbatore, India.
Introduction: Isolated fallopian tube torsion (IFTT) is an exceedingly rare but serious cause of acute abdominal pain, especially in pediatric patients, with a reported prevalence of 1 in 1.5 million women. It occurs when the fallopian tube twists around its own axis, leading to venous and lymphatic obstruction, ischemia, and potential necrosis, without involving the ipsilateral ovary.

Background: Griscelli syndrome (GS) is a rare genetic disorder characterized by oculocutaneous albinism and variable immune dysfunction. Among three distinct types of GS, occurring due to different genetic mutations; GS type 1 presents with neurological manifestations, hemophagocytic lymphohistiocytosis (HLH) generally develops in GS type 2, and GS type 3 primarily exhibits oculocutaneous albinism. HLH, a life-threatening condition with excessive immune activation, may occur secondary to various triggers, including infections, and develop in different tissues, as well as in the testis, similar to Erdheim-Chester disease.

Knee Surg Sports Traumatol Arthrosc
January 2025
Sports Medicine Service, Beijing Jishuitan Hospital, Capital Medical University, Beijing, China.
Purpose: To propose a new sign of patellar maltracking in recurrent patellar dislocation (RPD) and compare the differences in lower limb rotational and bony structural abnormalities among the different signs.
Patients And Methods: A retrospective study included 279 patients (mean age: 22 years; female: 81%) who underwent primary surgery for RPD over the past 4 years was performed. The patients were grouped based on the characteristics of patellar tracking: low-, moderate- and high-grade J-sign.
Pathophysiological effects of hypoxia on testis function and spermatogenesis.
Nat Rev Urol
January 2025
Discipline of Biological Sciences, College of Engineering, Science and Environment, The University of Newcastle, Callaghan, New South Wales, Australia.
Multiple conditions can cause hypoxia in the testis, including exposure to high altitude, sleep apnoea, testicular torsion and varicocele. Varicocele accounts for up to 44% of instances of primary infertility, but the cumulative contribution of hypoxic conditions to male infertility is undefined. Results of controlled hypobaric hypoxia studies have demonstrated a substantial detrimental effect of short-term and long-term exposures on sperm; however, downstream effects on embryo development and offspring health are less well understood.

Graefes Arch Clin Exp Ophthalmol
January 2025
Frankfurt Institute for Advanced Studies (FIAS), Frankfurt am Main, Germany.
Purpose: Our study presents a virtual reality-based tangent screen test (VTS) to measure subjective ocular deviations including torsion in nine directions of gaze. The test was compared to the analogous Harms tangent screen test (HTS).
Methods: We used an Oculus Go controller and head-mounted-display with rotation sensors to measure patient's head orientation for the VTS.
