Summary A survey of laryngeal mask airway usage in 1400 infants and children by ten trainee anaesthetists was undertaken to provide information about insertion complication rates using the standard technique a limited range standardised anaesthetic techniques. Placement successful 90% (1258/1400) at first attempt, 8% (112/1400) second attempt 2% (29/1400) required an alternative insertion. One patient vomited during procedure abandoned, hut aspiration did not occur. The overall problem rate...

Decidualized endometrial stromal cells from mid- to late secretory phase and decidual gestational human endometrium displayed prominent immunohistochemical staining for tissue factor, a primary initiator of hemostasis. Consistent with the regulation by progesterone decidualization process in vivo, medroxy-progesterone acetate elevated factor content cell cultures 8-fold over basal values. This increase paralleled release immunoreactive PRL, marker decidualization. The induced, as well basal,...

Due recent advances prenatal ultrasound and magnetic resonance imaging techniques, accurate utero diagnosis this teratoma will enable health care team prepare for "emergency" management difficult airway. We present case newborn large epignathus diagnosed prenatally who underwent tracheotomy intact maternal-fetal circulation. After stabilization, circulation was...

Potential involvement of immune system in pathophysiology congenital glaucoma, cataract, and retinopathy prematurity (ROP) infants has been suggested. However, its understanding still remains limited.

Introduction: Adjuvant treatment for patients with stage I non-seminomatous germ cell tumors (NSGCT) could be active surveillance (AS), chemotherapy, or retro-peritoneal lymph node dissection (RLND). AS is the preferred option in most cas-es. The aim of this study was to evaluate long-term survival and prognostic factors our population approach. Methods: We collected information from NSGCT testis medical records 1995 2016. Patients had negative serum tumor mark-ers imaging chest, abdomen,...

Background New methods of rapid opiate detoxification, under intravenous sedation, can detoxify heroin-addicted patients in 24 hours. Their clinical application has been limited by the lack studies establishing both efficacy and safety. Method In a randomised, controlled study, 300 treatment-refractory, received detoxification treatment (naloxone infusion, 0.06–0.08 mg/kg, then oral naltrexone 50 mg/day) either monitored light sedation or unmonitored deep sedation. Results All were...

This study examined steroidal regulation of tissue factor expression by cultured endometrial stromal cells. Confluent cell cultures derived from cycling human endometria were exposed to vehicle control, 10(-8) mol/L estradiol (E2), 10(-8)-10(-6) medroxyprogesterone acetate (MPA), or both E2 and MPA for 2-24 days in serum-containing medium. The progestin enhanced immunoreactive functionally active content, achieving peak effects 8-12 culture. Although alone was ineffective, it augmented...

Abstract Our objective was to assess the accuracy of ultrasonographic estimation fetal weight in twins and triplets as compared singleton pregnancies. Retrospective analysis undertaken ultrasound data all fetuses who underwent an examination within 1 week delivery (singletons 1832, 518, 51). At birth weights below 2500 g, there a significant overestimation singletons, but estimate same, except between 1500 2499 when based on abdominal circumference femur length alone. more than no difference...
