Carpal tunnel syndrome (CTS) is a common form of hand mononeuropathy that is typi-cally caused by median nerve compression. Although it is often idiopathic, CTS can also result from various conditions, including space-occupying lesions. Tumoral calcinosis, a rare condition characterized by periarticular deposition of calcified masses, is an un-common cause of secondary CTS. We present a case of a 78-year-old woman with idio-pathic tumoral calcinosis that caused secondary CTS. Despite conservative treatments, her symptoms persisted, and diagnostic imaging, including radiographs, computed to-mography, and magnetic resonance imaging, revealed a calcified mass in the carpal tun-nel. A surgical intervention involving carpal tunnel release and excisional biopsy con-firmed the diagnosis of tumoral calcinosis. Postoperatively, the patient showed complete resolution of symptoms, with no recurrence on follow-up radiographs. This case high-lights the importance of considering space-occupying lesions, such as tumoral calcinosis, as a rare but treatable cause of secondary CTS.

Purpose: This study was performed to identify risk factors associated with post-tonsillectomy hemorrhage (PTH)-related hospitalization in pediatric patients visiting an emergency department (ED). Methods: We retrospectively reviewed the medical records of patients who underwent tonsillectomy at a single children’s hospital ED from January 2009 through December 2020. Data were collected on patient demographics, chief complaints, surgical methods, postoperative days, initial vital signs, and laboratory findings. The study population was divided into hospitalized and discharged groups. Results: Among a total of 2,716 patients reviewed, 67 met the inclusion criteria. The hospitalized group showed a lower median systolic blood pressure (108.0 [interquartile range, 82.0-134.0] vs. 118.5 [89.8-147.2] mmHg; P = 0.021) and a faster median respiratory rate (23.0 [18.0-28.0] vs. 20.0 [17.0-23.0] breaths/minute; P = 0.019), compared with the discharged group. Multivariable logistic regression identified systolic blood pressure under 100 mmHg (odds ratio, 5.21; 95% confidence interval, 1.17-37.60) and respiratory rate over 24 breaths/minute (7.31; 1.07-145.79) as the factors associated with PTH-related hospitalization. Conclusion When pediatric patients visit EDs for PTH, close monitoring or hospitalization may be needed in those with low systolic blood pressure or rapid respiratory rate.

Objective: Preterm births in the late preterm period comprise more than half of all preterm births. However, perinatal outcome evaluation between singleton and multiple pregnancies is limited. This study aimed to compare the perinatal outcomes of preterm pre-labor rupture of membranes (PPROM) between twin and singleton pregnancies at 34 weeks to 36 weeks and 6 days. Methods: This retrospective case-control study included women with preterm births at the Tertiary Hospital between July 2006 and December 2023. We analyzed and compared the maternal and neonatal characteristics, especially intertwined neonatal morbidity and mortality, with those of singletons. Results: There were 52 twin and 317 singleton pregnancies. Women with twin pregnancies had shorter median latencies and fewer cases of histological chorioamnionitis than those with singleton pregnancies. Compared to the ruptured sac babies of twins and singletons, unruptured sac babies of twins had longer hospital stays and were more likely to require respiratory support and resuscitation immediately after delivery. Conclusion Maternal outcomes of twins and singletons after PPROM differed in latency and histologic chorioamnionitis, whereas neonatal outcomes demonstrated more acute respiratory problems and longer hospital stays in twin babies with unruptured sacs. More cautious respiratory care is needed for infants with an unruptured sac immediately after birth.
