The association of serum total sialic acid/total protein ratio with diabetic parameters in young type 1 diabetic patients.

Sialic acid is a terminal component of the non-reducing end of carbohydrate chains of glycoproteins and glycolipids. The purpose of this study was to estimate serum total sialic acid (TSA) concentrations and serum TSA/serum total protein (TP) ratios in young type 1 diabetic subjects and to investigate their association with diabetes-related parameters in that population. Twentyfour young type 1 diabetic patients and 20 healthy controls were enrolled in this study.

Neonatal hypertrichosis in an infant of a diabetic mother with congenital hypothyroidism.

Hypertrichosis in a newborn girl infant of a diabetic mother with congenital hypothyroidism is reported. Both neonatal hyperinsulism and increased testosterone levels were documented. The hypertrichosis resolved after 3 months' of thyroxine replacement treatment.

Obstructive jaundice due to a textiloma mimicking a common bile duct stone.

A foreign body is a rare cause of obstructive jaundice. We report a 19-year-old woman with jaundice caused by a surgical gauze in the common bile duct (CBD). Four yours earlier, she had undergone a cholecystectomy and drainage for hydatid disease of the liver.

Dynamic phase transition in the kinetic spin-1 Blume-Capel model under a time-dependent oscillating external field.

We study within a mean-field approach the stationary states of the kinetic spin-1 Blume-Capel model in the presence of a time-dependent oscillating external magnetic field. We use the Galuber-type stochastic dynamics to describe the time evolution of the system. We have found that the behavior of the system strongly depends on the crystal field interaction D .

Severe hyperinsulinaemic hypoglycaemia in a baby born to a mother taking oral ritodrine therapy for preterm labour.

Hyperinsulinism of infancy is a major cause of persistent hypoglycaemia in the newborn period. Transient mild self-limiting hyperinsulinaemia and hypoglycaemia have been described in neonates born to mothers taking ritodrine therapy for premature labour. Ritodrine crosses the placental barrier and enters the fetal circulation readily but the mechanism of how it causes hyperinsulinaemia and hypoglycaemia is unclear.

Laparoscopic splenectomy and LigaSure.

Laparoscopic splenectomy (LS) is a preferred choice, especially for hematologic diseases. We present the advantages of the use of LigaSure (energy-based equipment that works by applying a precise amount of bipolar energy and pressure to the tissue, achieving a permanent seal) for achieving a precise hemostasis, thus making the LS easier. We have performed LS using LigaSure on 10 patients (4 female, 6 male; mean age, 36 years [range, 16-58]) between December 2002 and August 2003.

Acanthosis nigricans in association with congenital adrenal hyperplasia: resolution after treatment. Case report.

A case is described of a three-day-old female with salt wasting type of 21-hydroxylase deficient congenital adrenal hyperplasia who presented with acanthosis nigricans of both axillae. Following corticosteroid and mineralocorticoid therapy for disease, the acanthosis nigricans resolved. It is believed that this is the first reported case of acanthosis nigricans occurring in association with congenital adrenal hyperplasia, a phenomenon that resolved after treatment.

Female pseudohermaphroditism due to classical 21-hydroxylase deficiency and insulin resistance in a girl with Turner syndrome.

We report five-year-old girl with female pseudohermaphroditism due to classical form of 21-hydroxylase deficiency associated with Turner's syndrome (45,X/46,XX) and insulin resistance. She had clitoromegaly since birth, but Turner's syndrome and 21-hydroxylase deficiency were diagnosed incidentally at one and five years of age, respectively. Moreover, we determined insulin resistance, which resolved following corticosteroid therapy for disease.

Treatment of chronic frontal sinus disease with the galeal-frontalis flap: a long-term follow-up.

Background: Management of benign chronic frontal sinus disease is difficult. Patients are frequently seen by multiple specialties for medical treatment and endonasal procedures before they seek or require definitive treatment with frontal sinus obliteration. The progression of the disease may lead to serious or life-threatening conditions such as local bone destruction, periorbital abscess, osteomyelitis, meningitis, cranial epidural abscess, or septicemia.

Homeostasis model assessment is more reliable than the fasting glucose/insulin ratio and quantitative insulin sensitivity check index for assessing insulin resistance among obese children and adolescents.

Objective: Simple fasting methods to measure insulin resistance, such as the homeostasis model assessment (HOMA), fasting glucose/insulin ratio (FGIR), and quantitative insulin sensitivity check index (QUICKI) methods, have been widely promoted for adult studies but have not been evaluated formally among children and adolescents. The aim of this study was to compare the HOMA, FGIR, and QUICKI methods for measuring insulin resistance, expressed by oral glucose tolerance test (OGTT) results, among obese children and adolescents.

Methods: Fifty-seven pubertal obese children and adolescents (30 girls and 27 boys; mean age, 12.

Compartmentalization of massive vascular malformations.

A total of 18 patients with massive vascular malformations of the head and neck region were treated with compartmentalization using nonabsorbable sutures followed by injection of a sclerosant agent into each compartment. The indication for compartmentalization was either to stop potentially uncontrollable, life-threatening hemorrhage during the dissection of the lesion or to reduce its vascularity to allow a less dangerous subsequent resection. Compartmentalization was used in both high-flow and low-flow vascular malformations.

Vulvovaginal candidiasis in children and adolescents with type 1 diabetes mellitus.

In this prospective study we investigated the frequency of vulvovaginal candidiasis, the results of yeast cultures and detection of ketoconazole resistance in female children and adolescents with type 1 diabetes mellitus (DM1). The study consisted of 35 patients with DM1 (age 1.7-20 years) and 22 controls (age 1.

Nonketotic Hyperosmolar Coma Associated With Splenic Rupture in Congenital Afibrinogenemia.

Nonketotic hyperosmolar coma is uncommon in children. Splenic rupture in congenital afibrinogenemia is also a rare event. The authors described a 5-year-old girl with congenital afibrinogenemia who presented with nonketotic hyperosmolar coma associated with spontaneous splenic rupture.

Bardet-Biedl syndrome with syndrome X: a patient report.

Bardet-Biedl syndrome (BBS) is an autosomal recessive condition with a wide spectrum of clinical features. The principal manifestations are rod-cone dystrophy (sometimes called atypical retinitis pigmentosa), postaxial polydactyly, central obesity, mental retardation, hypogonadism, and renal dysfunction. The clinical diagnosis of syndrome X defines a patient with abnormal glucose metabolism, hypertension, hyperlipidemia and obesity.

Relationship between cord blood levels of IGF-I and ferritin in healthy term neonates.

Objective: We hypothesize that the balance of maternal and fetal insulin-like growth factor-I (IGF-I) concentrations contributes to the regulation of substrate distribution between mother and fetus, and may thus mediate the maintenance of blood ferritin concentration in the fetus. Therefore, the relationship between cord blood IGF-I to ferritin concentration was investigated.

Infants And Methods: Twenty-six term neonates were recruited.

Use of the holmium:YAG laser for ureterolithotripsy in children.

Objective: To review our experience with rigid ureteroscopy and holmium:YAG laser for treating ureteric calculi in children.

Patients And Methods: The study included 35 children who were treated with rigid ureteroscopy for ureteric calculi between November 1997 and June 2003 (15 boys and 20 girls; mean age 6.2 years, range 1-14).

Enhancement of nerve regeneration and orientation across a gap with a nerve graft within a vein conduit graft: a functional, stereological, and electrophysiological study.

In this study, the right sciatic nerves of 40 rats were used to determine whether a nerve graft within a vein graft might accelerate and facilitate axonal regeneration, compared with a nerve graft alone. The animals were separated into four groups, as follows: group 1, sham control; group 2 (control), segmental nerve resection and no repair; group 3, segmental nerve resection and nerve grafting; group 4, segmental nerve resection and reconstruction with a nerve graft within a vein conduit graft. For all groups, sciatic functional indices were calculated before the operation and on postoperative days 7 and 90.
