Loa loa presenting in a ThinPrep Pap test: case report and review of parasites in cervicovaginal cytology specimens.

Parasites other than Trichomonas vaginalis may occasionally present in Pap tests obtained during gynecologic examination. We present a case of Loa loa found on a Pap test from an apparently healthy 19-yr-old woman who had immigrated to the US at the age of 15 from Cameroon. We discuss the cytologic features from this case and then briefly review Loa loa and the presence of parasites in Pap tests and other cervicovaginal specimens.

The Pallister-Killian syndrome in an African individual.

We report for the first time an individual of Zulu origin with the Pallister-Killian syndrome. Apart from the commonly reported clinical signs, he also had frenula in all four quadrants of the mouth. A broad, short hallux was present. An unusually high level of mosaicism for the isochromosome 12p was found in the lymphocytes.

Temporal and spatial control of transgene expression using laser induction of the hsp70 promoter.

BACKGROUND: Precise temporal and spatial regulation of transgene expression is a critical tool to investigate gene function in developing organisms. The most commonly used technique to achieve tight control of transgene expression, however, requires the use of specific DNA enhancers that are difficult to characterize in non-model organisms. Here, we sought to eliminate the need for this type of sequence-based gene regulation and to open the field of functional genetics to a broader range of organisms. RESULTS: We have developed a new laser mediated method to heat shock groups of cells that provides precise spatio-temporal control of gene expression without requiring knowledge of specific enhancer sequences. We tested our laser-system in a transgenic line of Bicyclus anynana butterflies containing the EGFP reporter gene attached to the heat sensitive hsp70 promoter of Drosophila melanogaster. Whole organismal heat shocks demonstrated that this Drosophila promoter can drive gene expression in butterflies, and the subsequent laser heat shocks showed that it was possible to activate cell-specific gene expression in very precise patterns on developing pupal wings. CONCLUSION: This laser-mediated gene expression system will enable functional genetic investigations, i.e., the ectopic expression of genes and their knock-down in targeted groups of cells in model and non-model organisms with little or no available regulatory data, as long as a compatible heat-shock promoter is used and the target tissue is accessible to a laser beam. This technique will also be useful in evolutionary developmental biology as it will enable the study of the evolution of gene function across a variety of organisms.

Anxiety in a neglected population: prevalence of anxiety disorders in pre-adolescent children.

It is widely believed that anxiety is a common disorder of childhood and adolescence, but epidemiological studies have varied substantially in the prevalence rates that they report. In addition, less attention has been paid to the prevalence of anxiety in pre-adolescent children. For these reasons, a review of epidemiological studies reporting on the prevalence of anxiety disorders in this younger population is described. A comprehensive literature search, encompassing electronic searches of databases and hand searches of journals, returned 11 studies that reported on the prevalence of DSM-III-R or DSM-IV anxiety, specifically in children aged below 12 years of age, which had employed certain minimum standards of epidemiological practice, and had some degree of generalisability to wider populations. The rates of diagnosis of 'any anxiety disorder' varied widely between the studies. The minimum figure reported was 2.6%, and the maximum was 41.2%. Separation Anxiety Disorder appeared to be the most common individual anxiety diagnosis in this age group. Anxiety disorders appear to be more common than depressive disorders, and probably also more common than disorders of behaviour. Anxiety disorders are, at the very least, fairly common in pre-adolescent children. This is concerning when the limited current treatment options for this age group are considered. Reasons for the varied prevalence rates reported by the studies, focussing on the differences in methods employed, are suggested. Implications for treatment are discussed.

Characterization of relative growth of empty body and carcass components for bulls from a five-breed diallel.

Slaughter and carcass data were obtained on 197 bulls produced in a diallel involving Angus, Brahman, Hereford, Holstein and Jersey that were slaughtered at either 6, 9, 12, 15, 18, 24, or 30 mo of age. Bulls were given ad libitum access to a 72% TDN diet on an individual basis from 6 mo of age until slaughter. Empty body weight (EBWT) was determined as the sum of the weights of blood, hide, hard drop, soft drop (minus contents of the digestive tract), and carcass weight (CWT), which were recorded at slaughter. Carcass protein (CPROT) and fat (CFAT) were based on weights and chemical analyses of lean and fat tissue and bone of the carcass. Empty body protein (EBPROT) and fat (EBFAT) were based on weights and chemical estimates of the components of the empty body. Growth of EBWT, EBPROT, EBFAT, CWT, CPROT, and CFAT relative to either live weight (LWT), EBWT, or CWT were investigated using the allometric equation. Breed-type differences existed (P less than .01) for the growth of EBWT relative to LWT. Comparisons of general combining abilities revealed that Angus, Hereford, and Jersey generally had lower maturing rates of EBWT relative to LWT and that Brahman and Holstein had higher maturing rates. Across breed-type, relative growth rates indicated that fat and protein were later-maturing components relative to LWT, EBWT, or CWT, which implies that other components mature relatively earlier. Relative maturing rates of components studied were not important in explaining differences in body composition that have been previously reported for these breed-types.

An amino acid substitution in the pyruvate dehydrogenase E1 alpha gene, affecting mitochondrial import of the precursor protein.

A mutation in the mitochondrial targeting sequence was characterized in a male patient with X chromosome-linked pyruvate dehydrogenase E1 alpha deficiency. The mutation was a base substitution of G by C at nucleotide 134 in the mitochondrial targeting sequence of the PDHA1 gene, resulting in an arginine-to-proline substitution at codon 10 (R10P). Pyruvate dehydrogenase activity in cultured skin fibroblasts was 28% of the control value, and immunoblot analysis revealed a decreased level of pyruvate dehydrogenase E1 alpha immunoreactivity. Chimeric constructs in which the normal and mutant pyruvate dehydrogenase E1 alpha targeting sequences were attached to the mitochondrial matrix protein ornithine transcarbamylase were synthesized in a cell free translation system, and mitochondrial import of normal and mutant proteins was compared in vitro. The results show that ornithine transcarbamylase targeted by the mutant pyruvate dehydrogenase E1 alpha sequence was translocated into the mitochondrial matrix at a reduced rate, suggesting that defective import is responsible for the reduced pyruvate dehydrogenase level in mitochondria. The mutation was also present in an affected brother and the mildly affected mother. The clinical presentations of this X chromosome-linked disorder in affected family members are discussed. To our knowledge, this is the first report of an amino acid substitution in a mitochondrial targeting sequence resulting in a human genetic disease.

Cystic testicular lesions in the pediatric population.

PURPOSE: We present the etiology, histological evaluation and management of all cystic lesions of the pediatric testis. MATERIALS AND METHODS: Illustrative cases from our experience are reported with a literature review of all possible diagnoses. RESULTS: Included in the differential diagnosis of cystic testis lesions in children are epidermoid cyst, dermoid cyst, prepubertal teratoma, juvenile granulosa cell tumor, cystic dysplasia of the rete testis, testicular cystic lymphangioma, simple cyst and cystic degeneration after torsion. Testis sparing surgery is feasible in many circumstances. CONCLUSIONS: Cystic lesions of the pediatric testis are rare but represent an interesting group of diagnoses. Patient age at presentation, examination features, tumor markers and sonographic appearance may assist in making a presumptive and occasionally definitive diagnosis preoperatively. Based on the likely diagnosis enucleation or partial orchiectomy may be considered when performed with frozen section histological assessment. A thorough understanding of potentially cystic testis lesions in children leads to the best management choices and often to preservation of a substantial portion of the affected testis.

REM sleep reduction, mood regulation and remission in untreated depression.

The contribution of increased rapid eye movement (REM) pressure through repeated, mild, reduction of (REM) sleep to remission from untreated depression was studied over a 5-month period in 20 depressed and 10 control volunteers. Sixty percent of the depressed subjects were in remission at the end of the study. Sixty-four percent of the variance in remission could be accounted for by four variables: the initial level of self-reported symptoms, the reported diurnal variability in mood, the degree of overnight reduction in depressed mood following interruptions of REM sleep and the quality of dream reports from these awakenings. Increased REM pressure is beneficial for those who are able to construct well-organized dreams.

Epididymal sarcoidosis.

Sarcoidosis is a multisystem disorder that rarely involves the genitourinary tract. To date only 28 cases of histologically proved sarcoidosis involving the epididymis have been described in the literature. Although uncommon, sarcoidosis should be considered in any differential diagnosis of testicular lesions. We present 2 cases of epididymal sarcoidosis. A 27-year-old asymptomatic black man had multiple nontender scrotal nodules on routine physical examination. A 34-year-old black man was initially diagnosed with sarcoidosis by transbronchial biopsy. He received 10 months of prednisone therapy before noticing a mass in the right testicle. Surgical exploration of both patients demonstrated noncaseating granulomatous inflammation consistent with sarcoidosis.
