[Recurrent urinary infection in girls. Natural history and therapeutic response].

A group of 39 girls with urinary tract infection are studied to analyse the clinical findings, response to treatment and natural history of the disease. All of them had more than three episodes of infection per year and renal function and initial cysto-urographic study were normal. Mean age at diagnosis was 4.8 years and the mean follow-up 3.4 years. In 7.6% of cases familial incidence was observed. During infection free periods, 35.8% of patients had urinary incontinence. 25% of recurrences were asymptomatic. Only one case developed during the follow-up a unilateral polar scar associated with grave II vesicoureteral reflux. Recurrence rate/girl/year, decrease from 3.8 during the first year to 1.5 at 5th year of follow-up. Patients who received prophylaxis with nitrofurantoin showed a clear decrease in rate of recurrence.

[Trisomy 5p: a report of 2 cases].

Authors report two patients from different families who present similar abnormalities caused by an "almost complete" trisomy of the short arm of chromosome 5 [case No. 1: 46, XY, der (20), t (5; 20) (p11;p13), mat; case No.2: 46, XY, dup (5p)]. Several family members of case No. 1 were balanced translocation carriers. Case No. 2 is probably due to de novo duplication. Clinical findings in our cases and those cited in the literature allow identification of certain main features characteristic of "almost complete" trisomy 5p: hypotonia, weak cry, mongoloid slant of eyes, epicanthus, depressed nasal bridge, auricular anomalies, bilateral cryptorchidism and, less frequently, macrocephaly, micrognathia and club feet.

Regulation of protein phosphorylation of the intermediate-sized filament vimentin in the ciliary epithelium of the mammalian eye.

The intermediate-sized filaments of vimentin-type (Mr = 57,000) have been identified biochemically and immunochemically as a major cytoskeleton component in the ciliary epithelium of the mammalian eye. When human or rabbit ciliary processes, or cultured ciliary epithelial-derived cells were incubated in serum-free medium containing [32P]orthophosphate and any of the following agents: 1) beta-adrenergic agonists (isoproterenol or epinephrine), 2) direct activators of adenylate cyclase (cholera toxin or forskolin), 3) analogs of cyclic AMP (8-Br-cAMP), or 4) prostaglandin E1, the phosphorylation of vimentin was significantly enhanced. The maximal enhancement ranged, in vivo and in vitro, from about 3-fold in human to 5-fold in rabbit, with either 1 mM 8-Br-cAMP or 0.1 microM forskolin. Phosphorylation of vimentin increased in the presence of beta-adrenergic agonists and could be blocked by the antiglaucoma beta-adrenergic antagonist timolol. The alpha-adrenergic agonist phenylephrine had no effect on phosphorylation of vimentin. Indirect immunofluorescence microscopy using a monoclonal antibody, anti-vimentin, allowed the localization of vimentin filaments in cultured ciliary epithelial cells. Treatment of these cells in culture with the catecholamine hormone, isoproterenol (1 microM), resulted in a profound reorganization of vimentin filaments. This may be correlated with the enhanced levels of phosphorylated vimentin observed upon increasing cellular cyclic AMP.

The detection and characterization of controlled drugs imported into the United Kingdom.

The Laboratory of the Government Chemist examines most of the drugs that have been seized at the point of entry into the United Kingdom of Great Britain and Northern Ireland and has developed analytical methods for their rapid identification in the field and for more exact analysis and quantitation in the Laboratory. These methods are described for the major types of drugs encountered. Many seizures are examined in greater detail in order to compare samples and to correlate origin with physical and chemical appearance. Information on the procedures necessary to undertake this aspect of work is also presented.
