I N 1998, a 37-year-old woman underwent bilateral same-day laser in situ keratomileusis (LASIK) surgery. The preoperative refraction was −6 diopters (D) for each eye. The surgery on the right eye was uncomplicated. On the left eye, the procedure was complicated by cornealperforation,probablydue tomisassembly of an older-generation microkeratome with a removable spacer plate. Despite surgical re...

In 327 newborns cord blood thyroxine (T4) was 11.8 +/- 0.4 mug/100 ml (SEM) (151.9 +/- 5.1 nmol/l), and serum thyrotrophin (TSH) 6.7+/-1.0 muU/ml. Variability was marked for both T4 and TSH. Remeasured in the same patients on the fifth day of life, the TSH level was 3.7 +/- 1.0 muU/ml, lower than at birth (P less than 0.001), while scattering of TSH values was much smaller, with 99.4 % of value...

BACKGROUND Laparoscopic Heller myotomy is the most effective therapy for achalasia. All case series have reported a minimum length of stay of more than 1 day. "True" day-case laparoscopic Heller myotomy has not been reported, so far. The aim of this study was to review our results with laparoscopic Heller myotomy with respect to the length of stay following the procedure. METHODS All patients...

OBJECTIVE To examine the relationship between body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) and 30-day mortality risk among patients in the participant use data file database of the American College of Surgeons National Surgical Quality Improvement Program. Obesity is a prevalent chronic disease in the United States, and general and vascular surgeo...

Cochlear implantation has become established worldwide as a safe and effective method of auditory rehabilitation of selected severely and profound deaf children and adults. Over 100,000 patients have received cochlear implants worldwide with the paediatric population proving to be the main beneficiaries. The Libyan cochlear implant programme was set up in 2004. Data relating to the patients who...

OBJECTIVE To increase access to early second-trimester surgical abortion by determining noninferiority of same-day synthetic osmotic dilators compared with overnight Laminaria for cervical preparation before early second-trimester dilation and evacuation. METHODS We enrolled women between 14 and 18 weeks of gestation and randomized them to same-day synthetic osmotic dilators or overnight Lami...

Introduction. It is known that under many conditions, effective operators will be partial recursive, ([MS], [KLS], [L]). On the other hand, certain pathological examples have been constructed by Friedberg [F] and Pour-El [P] to show that effective operators are not always partial recursive. Pour-El has observed that although it is well known that all partial recursive operators are continuous, ...

the objective of this study was to determine the efficacy of two procedures i.e. feeding and immersion followed by feeding, for masculinizing blue hap. two experiments (experiments i and ii) were conducted. in experiment i, feeding hormonal treatment was applied on post-yolk sac stage fry (10 days after fertilization at 27ºc). dosages of 30mg (group a) and 60mg (group b) of 17α-methyltestostero...

In the current study, we sought to establish a novel rat model of portal vein arterialization (PVA) and evaluate its impact on liver regeneration after extended partial hepatectomy (PH). A total of 105 Sprague-Dawley rats were randomly assigned to three groups: 68% hepatectomy (the PH group), portal arterialization after 68% hepatectomy (the PVA group), and right nephrectomy only (the control g...
