Detection of respiratory syncytial virus in children in the 1993-94 winter season in Izmir, Turkey, by two diagnostic methods.

Respiratory syncytial virus (RSV) infection was searched for in 65 children between 2 months and 2 years of age hospitalized with the presumptive diagnosis of acute bronchiolitis, and in 35 children aged 6 months to 8 years with upper respiratory tract symptoms, by direct fluorescent antibody (DFA) test and cell culture. RSV infection was detected in 29.2% of the first and in 11.4% of the second group. The overall positivity rate was 23%. The sensitivity and the specificity of the commercially available DFA test in comparison with cell culture were 81.8% and 92.5%, respectively.

Effects of analgesia of the distal interphalangeal joint or palmar digital nerves on lameness caused by solar pain in horses.

OBJECTIVE: To determine if pain of the dorsal margin of the sole in horses can be attenuated by anesthesia of either the distal interphalangeal (DIP) joint or the palmar digital (PD) nerves. STUDY DESIGN: A unilateral forelimb lameness was induced by creating solar pain. Response to administration of local anesthetic or saline solution into the DIP joint and to administration of local anesthetic around the PD nerves was evaluated. ANIMALS: Six horses. METHODS: Lameness was induced by creating pressure on the dorsal margin of the sole by screwing set-screws into a nut welded to the inside of each branch of a shoe. Gaits were evaluated before and after application of set-screws and after a local anesthetic or saline solution was administered into the DIP joint and, in a second trial, after a local anesthetic was injected around the PD nerves. Gaits recorded on videotape were evaluated, and lameness scores were assigned to each gait. RESULTS: Lameness scores were high after application of set-screws and remained high after saline solution was administered into the DIP joint. Scores decreased significantly (P < or = .05) after a local anesthetic was administered into the DIP joint or around the PD nerves. CONCLUSIONS: Analgesia of the DIP joint or the PD nerves desensitizes at least a portion of the sole. CLINICAL RELEVANCE: Pain arising from the sole should not be excluded as a cause of lameness when lameness is attenuated by analgesia of the DIP joint or PD nerves.

Maternal and fetal serum insulin-like growth factor-I (IGF-I) IGF binding protein-3 (IGFBP-3), leptin levels and early postnatal growth in infants born asymmetrically small for gestational age.

This study was planned to investigate the relationship between birth weight and insulin-like growth factor-I (IGF-I), IGF binding protein-3 (IGFBP-3), and leptin levels in neonates with normal growth (appropriate for gestational age: AGA) and retarded growth (small for gestational age: SGA); and to evaluate these growth factors' effects in early postnatal growth. All newborns were full-term: gestational age 3,841 weeks. Of 50 neonates, 25 were SGA. IGF-I, IGFBP-3 and leptin levels were measured in maternal serum and venous cord blood at birth and at 15 days of life of neonates using specific RIAs. Maternal serum leptin concentrations were significantly higher than cord blood leptin concentrations (p < 0.001). Maternal serum IGF-I, IGFBP-3 and leptin levels did not show correlations with birth weight. In contrast, there were significantly positive correlations between birth weight and venous cord blood IGF-I, IGFBP-3 and leptin levels (p < 0.001). In the SGA group, the newborns with a slow postnatal growth pattern had lower umbilical cord serum IGF-I levels compared with newborns with a normal growth pattern. A similar result was also found in the AGA group. Similar results were not found for serum leptin and IGFBP-3. In conclusion, cord blood IGF-I, IGFBP-3 and leptin levels play an important role in the regulation of fetal and neonatal growth. It is likely that IGF-I has a more important role than the other factors in early postnatal growth.

Familial brachyolmia.

Brachyolmia is characterized clinically by short stature and radiographically by generalized platyspondyly without significant long bone abnormalities. A healthy 13-(8/12) year-old girl was referred for evaluation of short stature. The parents were first cousins. She had two older brothers and a younger brother and sister. On examination, her height was 116.2 cm, height SDS -6.2, armspan 135 cm. She had completed puberty. Except for her short trunk and lower extremities and mild scoliosis, she appeared normal. At 12 years old, the younger brother had short stature. His height was 104.7 cm, height SDS -6.2, armspan 116 cm. The younger sister was 3 years old. Her height was 84.2 cm, height SDS -2.9, armspan 85 cm. Other findings were normal in the younger sister and brother. The other members of the family were of normal stature and appearance. The proband's growth hormone stimulation tests, thyroid function tests, sex steroids, gonadotropins and blood biochemistry were found normal. There were similar radiological findings in the three siblings. There was platyspondyly, narrowing of intervertebral spaces in all vertebral bodies. The iliac bones were broad. No metaphyseal irregularity and normal epiphyses were detected in all patients. No significant changes were seen in long bones and skull. According to the physical and radiological findings, the patients were evaluated as brachyolmia.

Inhalation therapy with magnesium sulfate and salbutamol sulfate in bronchial asthma.

Inhalation therapy with magnesium sulfate and salbutamol sulfate was applied to two groups, each consisting of 20 patients with acute asthma. The effects of inhaled magnesium sulfate and salbutamol sulfate were compared. The evaluation of patients was done using respiratory score, peak expiratory flow rate with a Wright peak flow meter, respiration rate, heart rate and blood pressure. Although magnesium sulfate's bronchodilating effect continued for approximately one hour, treatment of acute asthma using salbutamol sulfate inhalation was found to be more successful and its effect continued for six hours.

Comparison of growth, serum prealbumin, transferrin, IgG and amino acids of term infants fed breast mild or formula.

This study was designed to compare growth parameters, biochemical indices of protein metabolism and serum amino acid patterns in newborn infants fed either human milk (n: 22) or formula with protein and amino acid concentrations similar to human milk (n: 19) during the first two months of life. Growth parameters were normal and similar in all infants. Serum levels of transferrin and IgG were not significantly different, whereas prealbumin concentrations were found to be significantly higher in infants fed formula compared to those fed human milk. In the formula group, glutamic acid and cystine levels were significantly lower while phenylalanine and proline were significantly higher compared to the breastfed group. It was observed that feeding a formula with an amino acid pattern similar to that of human milk does not necessarily give rise to identical patterns of amino acids or indices of protein metabolism.
