Mortality and morbidity of extremely low birth weight infants in Japan, 2015.

Background: In Japan, the mortality rate of extremely low birth weight (ELBW) infants is notably low in comparison with other developed countries, but the prevalence of chronic lung disease (CLD) and retinopathy of prematurity (ROP) is relatively high. This study aimed to estimate the mortality and morbidity of ELBW infants born in 2015 who were admitted to neonatal intensive care units (NICUs) in Japan and to examine the factors that affected the short-term outcomes of these infants. We also compared the mortality of ELBW infants born in 2005, 2010, and 2015.

Medical care of newborns born to mothers with confirmed or suspected severe acute respiratory syndrome coronavirus 2 infections in Japan.

Background: There are currently no definitive guidelines regarding newborns born to mothers with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. This study aimed to investigate the medical care and management that provided or would provide for such newborns.

Methods: A web survey was conducted between September and October 2020.

A Blauth IIIB hypoplastic thumb reconstructed with a vascularised metatarso-phalangeal joint transfer: a case report with 28 years of follow up.

We reconstructed the Blauth-IIIB hypoplastic right thumb of a 16-year-old girl with a vascularised metatarso-phalangeal (MTP) joint from her second toe combined with a dorsalis-pedis flap. Abduction was provided with an abductor policis long tendon advancement, and adduction, with an extensor indicis proprius tendon transfer. Opponoplasty was performed one year later using the flexor sublimis (IV) tendon.

Predicting functional recovery and return to work after mutilating hand injuries: usefulness of Campbell's Hand Injury Severity Score.

Purpose: We investigated the effect of severity and form of mutilating hand injuries on functional recovery and return to work, and the usefulness of an injury-severity score in predicting these outcomes.

Methods: We reexamined patients in whom finger amputation or near amputation had been treated with replantation or revascularization at our institution at least 3 years earlier. We evaluated radiographs, sensory recovery, finger range of motion, skin temperature, and current overall hand function to calculate Tamai and Quick Disabilities of the Arm, Shoulder, and Hand scores, and recorded return-to-work status, duration of treatment, and time away from work.

Fetal growth restriction associated with measles virus infection during pregnancy.

We report on a 28-week infant with growth restriction starting after 23 weeks' gestation because of measles virus (MV) infection of the mother. Histological findings for the placenta revealed extensive fibrin deposition and necrosis of the villi, and MV antigen was demonstrated in the syncytiotrophoblast by immunostaining. The MV-specific IgM level in the infant was negative, but that of the mother was positive.

Long-term clinical and neurologic recovery in the hand after surgery for severe cubital tunnel syndrome.

Purpose: Functional outcomes of cubital tunnel surgery may decline as the severity of preoperative ulnar neuropathy increases. When functional recovery will be adequate, or whether tendon transfers should be required, may be unclear. We investigated the extent of functional recovery, the duration of the recovery process, and the necessity of restoring intrinsic muscle function in patients with severe cubital tunnel syndrome after surgery.
