Reducing child hazards in the home. A joint venture in injury control.

Injuries are a leading cause of childhood mortality and morbidity in the home, particularly in children less than 6 years of age. In an effort to prevent childhood injuries, the Hennepin County Burn Center began a joint venture with a public health agency to reduce home hazards for children less than 6 years of age who were treated at the burn center. Children were referred to a public health nurse for a home safety assessment. During the initial visit, child hazards were identified and recommendations were made for reducing injury risk. Parental compliance with recommendations was evaluated during a second home visit approximately 1 month later. Home safety assessments were completed in 21 homes, and a total of 131 recommendations were made. Burn prevention recommendations accounted for 43.5% of the total recommendations, poison control recommendations accounted for 36.6%, and other injury control recommendations accounted for 19.9%. Parents complied with 43.5% of the total 131 recommendations. Burn prevention recommendations had a compliance rate of 42%. Poison control recommendations had the highest rate of compliance at 58%. Other injury control recommendations had a compliance rate of 19%. The program had a positive effect on reducing home hazards. It was an appropriate response by practitioners already involved in the care of children, many of whom are at risk of injury.

Asymptomatic Chlamydia trachomatis urethritis in men.

Ten men with asymptomatic urethritis due to Chlamydia trachomatis were identified through culture screening and were treated with ceftriaxone (1 g given intramuscularly). Seven of the eight men who were followed for at least 21 days before and after therapy remained asymptomatic but culture-positive. One originally asymptomatic man had onset of symptomatic non-gonococcal urethritis 18 days after his first positive culture. Among asymptomatic men with positive cultures, pyuria was present in urine specimens obtained at 17 of 18 visits, while the leukocyte count on the urethral gram stain was above normal at ten of 29 visits (P less than .01). Therefore, one may conclude that ceftriaxone (1 g given intramuscularly) was ineffective therapy for chlamydial urethritis; male urethral infection with C. trachomatis can remain asymptomatic for 21-45 days; and in this population pyuria detected by urinalysis correlates better with infection than does a urethral gram stain.

Coffin-Lowry syndrome and premature tooth loss: a case report.

Coffin-Lowry syndrome was first described by Coffin in 1966 and later by Lowry in 1971. Several oral manifestations have been described previously. We report a case with additional information on the histology of prematurely exfoliated teeth.

Persistence of Mycoplasma hominis after therapy: importance of tetracycline resistance and of coexisting vaginal flora.

In past studies Mycoplasma hominis has persisted after treatment with placebo, penicillins, or rifampin in 88-97% of women and 49-77% of men with infections of the lower genital tract. Among women with nonspecific vaginitis, M. hominis persisted in only a third of those treated with metronidazole as compared with at least 70% of those treated with ampicillin (P = 0.01), even though M. hominis is resistant in vitro to metronidazole and to its acid and hydroxy metabolites. Persistence of M. hominis after treatment with metronidazole was significantly associated with persistence of Bacteroides species in the vagina (P = .03). These results suggest that colonization of the vagina with M. hominis is partly dependent on other components of the vaginal microbial flora. In prior studies, M. hominis has persisted in zero to 50% of women and in zero to 30% of men after treatment with tetracycline or lincomycin, but the role of tetracycline resistance in treatment failure was not defined. The susceptibility of M. hominis to tetracycline is bimodal; and the minimal inhibitory concentration (MIC) of tetracycline for strains isolated before or soon after treatment was greater than or equal to 16 micrograms/ml for seven (78%) of nine that did persist and for two (17%) of 12 that did not persist after tetracycline therapy for cervicitis in women (P = .002). The MIC of tetracycline was greater than or equal to 16 micrograms/ml for two (12%) of 17 isolates from women in Seattle in 1972-1973, as compared with 27 (34%) of 79 isolates from Seattle men and women in 1979-1982.(ABSTRACT TRUNCATED AT 250 WORDS)

Microangiopathic glomerulopathy in children with sickle cell anemia.

We studied kidney biopsy specimens from three children with sickle cell anemia and microangiopathic glomerulopathy. One child also had cyanotic congenital heart disease. Laboratory evaluation revealed proteinuria and normal serum creatinine in all and normal serum complement in two of the three children at the time of biopsy. In all biopsies, glomeruli were enlarged with diffuse hypercellularity and focal segmental mesangial interposition; capillary loop lumens were congested with sickled erythrocytes. Immune labeling identified segmental immunoglobulin G, C3, and properdin over the glomerular capillary loop walls in each case. Ultrastructurally, the subendothelial zone of the glomerular basement membrane was widened with new lamina densa formation with focal mesangial interposition. The glomerular lesion we describe in these children may be due to endothelial injury related to the altered erythrocytes, glomerular hemodynamics, and the hypercoagulable state characteristic of sickle cell disease.
