Long-term effects of dexamethasone on hearing ability in children with pneumococcal meningitis.

Controlled trials concerning adjuvant dexamethasone therapy in bacterial meningitis do not point unequivocally to a beneficial effect on hearing ability. We investigated the remote adverse outcomes of pneumococcal meningitis and, if any, beneficial effects of adjuvant dexamethasone therapy on hearing ability. Fifty-five subjects who experienced pneumococcal meningitis between 1987-97 were divided into two groups as 25 subjects who did not receive dexamethasone (Group 1) and the remaining 30 subjects who did (Group 2).

Management of evacuee surge from a disaster area: solutions to avoid non-emergent, emergency department visits.

Introduction: Many emergency departments (EDs) in the United States experience daily overcrowding, and a rapid influx of evacuees fleeing a disaster area can pose a substantial burden. Some of these evacuees may require ED care. However, others lack an alternative to the ED to address non-emergent medical concerns (prescription refills or outpatient referral).

Lymphocytes subsets in children with febrile convulsions.

In this study, lymphocytes subsets including blood CD3, CD4, CD8, CD16, CD19, and CD56 values were analyzed in children with febrile convulsion (FC) to determine whether there was the association of lymphocytes subsets in the pathogenesis of FC. The study includes 48 children with FC, and 55 healthy age matched control subjects, followed in Yüzüncü Yil University, Faculty of Medicine, Department of Pediatrics between October 2003 and June 2004. Blood CD3, CD4, CD8, CD16, CD19, and CD56 values were examined in the study and control groups.

Case report of two siblings with familial ovarian dysgenesis.

Two sisters were admitted separately at different times (ages 15 and 12 years, respectively) to our unit because of amenorrhea, lack of secondary sex characteristics, and short stature. No evidence of other congenital anomalies was found. Laboratory studies indicated hypergonadotropic hypogonadism.

Complex urogenital malformation associated with female pseudohermaphroditism: caudal dysgenesis syndrome.

Caudal dysgenesis syndrome is a rare cause of female pseudohermaphroditism. This syndrome consists of absent perineal and anal openings in association with ambiguous genitalia, urogenital, colonic, and lumbosacral anomalies. We report a case of caudal dysgenesis syndrome in an infant who had non-palpable testes, bifid scrotum, a phallus-like structure and urethral atresia.

Energy transfer in unsymmetrical phenylene ethynylene dendrimers.

We have applied the fluorescence upconversion technique to explore the electronic excitation energy transfer in unsymmetrical phenylene ethynylene dendrimers. Steady-state emission spectra show that the energy transfer from the dendrons to the core is highly efficient. Ultrafast time-resolved fluorescence measurements are performed at various excitation wavelengths to explore the possibility of assigning absorption band structures to exciton localizations.

The role of exciton hopping and direct energy transfer in the efficient quenching of conjugated polyelectrolytes.

The dynamics of fluorescence quenching of a conjugated polyelectrolyte by a cyanine dye are investigated by femtosecond fluorescence up-conversion and polarization resolved transient absorption. The data are analyzed with a model based on the random walk of the exciton within the polymer chain and a long-range direct energy transfer between polymer and dye. We find that rapid intrachain energy migration toward complex sites with the dye leads to the highly efficient energy transfer, whereas the contribution from direct, long-range energy transfer is negligible.

Bilateral brachial plexopathy complicating Henoch-Schönlein purpura.

An 11-year-old boy presented with convulsion, fever, rash, abdominal pain, swelling on the eyelids, elbow and wrists, oliguria and hematuria. Based on the abnormal findings the patient was diagnosed with Henoch-Schönlein purpura. On the 3rd day of admission, neurological examination showed ataxic gait, loss of deep tendon reflexes, and decreased (4/5) of muscle strength on all extremities.

Acute effect of nebulized budesonide in asthmatic children.

The acute anti-inflammatory effects of inhaled steroids at high doses and their use at home and as emergency treatment of acute asthma attacks in children have been evaluated in many clinical studies. However very little is known about their additional bronchodilator response to systemic steroids plus nebulized salbutamol in the early management in children. Asthmatic patients aged between 5-15 years were investigated in a double-blind, placebo-controlled fashion.

Methods: Two groups of Swiss albino mice received daily intra-muscular injections of gentamicin for 30 days. One of the groups received trimetazidine intra peritoneally in addition to the gentamicin.

Testing emergency medical personnel response to patients with suspected infectious disease.

Objectives: In the United States (US), hospitals are required to have disaster plans and stage drills to test these plans in order to satisfy the Joint Accreditation Commission of Healthcare Organizations. The focus of this drill was to test if emergency response personnel, both prehospital and hospital, would identify a patient with a potentially communicable infectious disease, and activate their respective disaster plan.

Methods: Twelve urban/suburban emergency departments (ED) received patients via car and ambulance.

Amplified quenching of a conjugated polyelectrolyte by cyanine dyes.

The conjugated polyelectrolyte PPESO3 features a poly(phenylene ethynylene) backbone substituted with anionic 3-sulfonatopropyloxy groups. PPESO3 is quenched very efficiently (KSV > 10(6) M(-1)) by cationic energy transfer quenchers in an amplified quenching process. In the present investigation, steady-state and picosecond time-resolved fluorescence spectroscopy are used to examine amplified quenching of PPESO3 by a series of cyanine dyes via singlet-singlet energy transfer.

Four children with colchicine poisoning.

Colchicine poisoning is a rare event. It is characterized by multiorgan involvement and by poor prognosis associated with overdose. In this article we present four children with colchicine poisoning to emphasize that colchicine poisoning has a large spectrum in childhood.

A review of 35 cases of asymmetric crying facies.

A review of 35 cases of asymmetric crying facies: Congenital asymmetric crying facies (ACF) is caused by congenital hypoplasia or agenesis of the depressor anguli oris muscle (DAOM) on one side of the mouth. It is well known that this anomaly is frequently associated with cardiovascular, head and neck, musculoskeletal, respiratory, gastrointestinal, central nervous system, and genitourinary anomalies. In this article we report 35 ACF patients (28 children and 7 adults) and found additional abnormalities in 16 of them (i.
