Endothelial cell adhesion molecule expression and lymphocyte adhesion to endothelial cells: effect of nitric oxide.

Interactions between circulating leukocytes and vascular endothelial cells are of fundamental importance in controlling normal recirculation and migration of cells into sites of inflammation. Nitric oxide (NO), which is synthesized by vascular endothelial cells, has been reported to decrease the binding of platelets, monocytes, macrophages, and neutrophils to endothelial cells. Using NO donors and inhibitors of the enzyme NO synthase, we found no evidence that physiologically relevant levels of NO alter adhesion of purified lymphocytes to an endothelial cell line derived from human umbilical vein endothelial cells (SGHEC-7). In addition, NO donors did not alter the cell surface expression of VCAM-1, ICAM-1, or E-selectin on SGHEC-7 cells.

Non-Hodgkin's lymphoma: case control epidemiological study in Yorkshire.

This paper reports the results of a case control study of non-Hodgkin's lymphoma in the Yorkshire Health Region. In all, 437 cases and 724 controls were interviewed. Risk factors associated with past skin conditions, family history of cancer and infectious mononucleosis, aspects of social life and contact with wood dust and epoxy glues all emerge. A comparison of high and low grade morphological forms of disease reveal contrasting risks and suggest separate aetiologies for these conditions.

Activation of the pp60c-src protein kinase is an early event in colonic carcinogenesis.

Colonic neoplasia provides an opportunity to study tumor progression because most carcinomas arise from adenomas (polyps), which, in turn, arise from normal epithelia. The malignant potential of adenomas varies with size, histology, and degree of dysplasia. Polyps that are less than 2 cm with villous architecture and severe dysplasia are most likely to contain carcinoma. Previous studies demonstrated that the in vitro protein-tyrosine kinase activity of pp60c-src from colon carcinomas is significantly higher than that from adjacent normal mucosa. Here we report that the protein kinase activity of pp60c-src is also elevated in colonic polyps. Activity is highest in malignant polyps and in greater than 2-cm benign polyps that contain villous structure and severe dysplasia. Thus, pp60c-src activation occurs in benign polyps that are at greatest risk for developing cancer. These data suggest that activation of the protooncogene product pp60c-src may be an important event in the genesis of human colon carcinoma.

Oral appliances for snoring and obstructive sleep apnea: a review.

We conducted an evidence-based review of literature regarding use of oral appliances (OAs) in the treatment of snoring and obstructive sleep apnea syndrome (OSA) from 1995 until the present. Our structured search revealed 141 articles for systematic scrutiny, of which 87 were suitable for inclusion in the evidence base, including 15 Level I to II randomized controlled trials and 5 of these trials with placebo-controlled treatment. The efficacy of OAs was established for controlling OSA in some but not all patients with success (defined as no more than 10 apneas or hypopneas per hour of sleep) achieved in an average of 52% of treated patients. Effects on sleepiness and quality of life were also demonstrated, but improvements in other neurocognitive outcomes were not consistent. The mechanism of OA therapy is related to opening of the upper airway as demonstrated by imaging and physiologic monitoring. Treatment adherence is variable with patients reporting using the appliance a median of 77% of nights at 1 year. Minor adverse effects were frequent whereas major adverse effects were uncommon. Minor tooth movement and small changes in the occlusion developed in some patients after prolonged use, but the long-term dental significance of this is uncertain. In comparison to continuous positive airway pressure (CPAP), OAs are less efficacious in reducing the apnea hypopnea index (AHI), but OAs appear to be used more (at least by self report), and in many studies were preferred over CPAP when the treatments were compared. OAs have also been compared favorably to surgical modification of the upper airway (uvulopalatopharyngoplasty, UPPP). Comparisons between OAs of different designs have produced variable findings. The literature of OA therapy for OSA now provides better evidence for the efficacy of this treatment modality and considerable guidance regarding the frequency of adverse effects and the indications for use in comparison to CPAP and UPPP.

Expression of a Hox gene, Cnox-2, and the division of labor in a colonial hydroid.

We report the isolation and expression of the Hox gene, Cnox-2, in Hydractinia symbiolongicarpus, a hydrozoan displaying division of labor. We found different patterns of aboral-to-oral Cnox-2 expression among polyp polymorphs, and we show that experimental conversion of one polyp type to another is accompanied by concordant alteration in Cnox-2 expression. Our results are consistent with the suggestion that polyp polymorphism, characteristic of hydractiniid hydroids, arose via evolutionary modification of proportioning of head to body column.

Antibiotic prophylaxis in gastrointestinal endoscopy: a report by a Working Party for the British Society of Gastroenterology Endoscopy Committee.

Antibiotic prophylaxis is recommended for endoscopic procedures if the patient is at high risk of endocarditis or of symptomatic bacteraemia as a consequence of immunosuppression or neutropenia. In most circumstances parenteral amoxycillin and gentamicin are recommended. The addition of parenteral metronidazole is recommended in patients with neutropenia. Vancomycin or teicoplanin are recommended in patients allergic to penicillin. Antibiotic prophylaxis is recommended for all patients undergoing ERCP with evidence of biliary stasis or pancreatic pseudocyst. Oral ciprofloxacin or parenteral gentamicin (or parenteral quinolone, cephalosporin or ureidopenicillin) are recommended for ERCP.

Tunica vaginalis blanket wrap to prevent urethrocutaneous fistula: an 8-year experience.

An 8-year review of hypospadias repair in patients with a meatus proximal to the coronal margin is reported. Fistula rates were compared among 4 groups: 1) loupe magnification, 2) tunica vaginalis blanket wrap tissue interposition with loupe magnification, 3) operating microscope magnification and 4) tunica vaginalis blanket wrap tissue interposition in conjunction with operating microscope magnification. Rate of fistula formation with loupe magnification alone was 20%, microscope magnification alone was 12% and tunica vaginalis blanket wrap interposition with loupes was 9%. When tunica vaginalis blanket wrap tissue interposition was used in conjunction with intraoperative microscopy no fistulas resulted.

The contribution of dream masochism to the sex ratio difference in major depression.

Twenty-five women and twenty-one men undergoing divorce had three laboratory nights of sleep on two occasions 1 year apart. On the third night, dream reports were elicited from subjects for each period of rapid eye movement (REM) sleep. Three groups differing on dream "masochism" were compared on personality, sex role, and social adjustment. Women "masochistic" dreamers had significantly higher scores on a scale of negative aspects of traditional feminine sex role identity than men or women without such dreams. They also showed less improvement at followup and had more need for emotional support. Dream masochism may be a continuing cognitive characteristic that contributes to the vulnerability of women to major depression.

The elderly victim of rape.

A common misconception about sexual assault is that the rapist is motivated by a sexual desire stimulated by a victim seductive in her behavior or dress. A retrospective analysis of 740 reported sexual assaults revealed 21 cases involving a victim between the ages of 60 and 90 years of age. The elderly victim was more often white and the assailant more often black than when younger victims are involved. Also, the data suggest that the rape of elderly women may involve a relatively few rapists, and that their assaults are of a serial nature. This study concludes that these rapists are motivated by anger, possibly racially related, and a need to express power, rather than by sexual desire.

Self-reported sleep disorder symptoms in epilepsy.

Three groups of adult epileptic subjects with simple partial, complex partial, and generalized seizures and normal control subjects completed a brief self-report sleep questionnaire. The simple partial and complex partial groups indicated significantly more sleep disorder symptoms, especially frequent night awakenings. The generalized group was most similar to the controls. Irrespective of seizure type, the epileptic patients with the most frequent seizures also had the most sleep disturbances. Sleep disorder symptoms did not increase with age in the seizure groups. It would thus seem that epileptic patients with partial seizures and those with more frequent seizures are at risk for developing sleep disorders.

Genetic mapping of the hemochromatosis locus on chromosome six.

The purpose of this paper is to report a pedigree with hereditary hemochromatosis in which a recombination between the HLA-A and B loci occurred. Both the maternal and paternal HLA-A3, B7 haplotypes were carrying an allele for hemochromatosis. The A3, B12 haplotype of the proband was a recombinant of the maternal A3, B7 and A28, B12 haplotypes. The hemochromatosis locus segregated with the HLA-A locus and not with the HLA-B locus. Thus, the hemochromatosis locus maps in close proximity to the HLA-A locus.

Chocolate craving among children: implications for disordered eating patterns.

The aim was to test the validity of a multidimensional model of chocolate craving among children, and to examine if the dimensions underlying the model predict consumption and eating disordered symptoms. Participants were 602 children (53% female) aged 11, 12, and 13 from 11 schools in Western Australia. Measures included the Orientation to Chocolate Questionnaire (OCQ) designed to assess three components of chocolate craving (approach, avoidance, and guilt), questions assessing body image dissatisfaction and dieting, and body mass index (BMI). Using structural equation modeling, results confirmed that chocolate craving among children is best conceptualized as a three-factor model (approach, avoidance, guilt). The underlying dimensions were differentially associated with self-reported chocolate consumption and indicators of disordered eating patterns. After controlling for BMI and gender, chocolate-related guilt was strongly associated with greater body dissatisfaction and dieting, and avoidance inclinations were also associated with dieting. Chocolate-related guilt was higher in girls than in boys. Results suggest that children experience chocolate craving as a multidimensional phenomenon reflecting some ambivalence. A gender difference in chocolate-related guilt appears to emerge in childhood, potentially contributing to a greater risk for girls to develop exaggerated concerns about body shape and weight.

The morphology of bone mineral crystals.

Electron microscopical observations of the size and shape of bone mineral crystallites have not been in complete agreement with X-ray diffraction findings. The two prevalent viewpoints consider bone mineral crystals to be either rod, or plate like in habit. There appears to be agreement that the smallest dimension of the crystals is about 5 nm, but there is discrepancy in the reported c-axial lengths. The method of dark field imaging is used to obtain a quantitative measurement of the c-axial length distribution in rabbit, ox and human bone: mean c-axial lengths 32.6 nm, 36.2 nm and 32.4 nm, respectively, show no significant difference at the 5% level to the mean c-axial length measured by X-ray line broadening. Both bright and dark field images strongly suggest that bone mineral has a plate like form. Reasons for past discrepancies are discussed.

In vivo topological analysis of Ste2, a yeast plasma membrane protein, by using beta-lactamase gene fusions.

Gene fusions were constructed between Ste2, the receptor for the Saccharomyces cerevisiae alpha-factor, and beta la, the secreted form of beta-lactamase encoded by the bla gene of pBR322. The Ste2 and beta la components were linked by a processing fragment (P) from the yeast killer preprotoxin containing a C-terminal lysine-arginine site for cleavage by the Golgi-associated Kex2 protease. Ste2 is predicted to have a rhodopsinlike topology, with an external N terminus and seven transmembrane segments. Fusions to three of the four Ste2 domains predicted to be external resulted in beta la secretion from yeast cells. A fusion at a site just preceding the first transmembrane segment was an exception; the product was cell associated, indicating that the first 44 residues of Ste2 are insufficient to direct secretion of beta la; translocation of this domain presumably requires the downstream transmembrane segment. Expression of fusions located in two domains predicted to be cytoplasmic failed to result in beta la secretion. Following insertion of the preprotoxin signal peptide (S) between the Ste2 and P components of these cytoplasmic fusions, secretion of beta la activity occurred, which is consistent with inversion of the orientation of the beta la reporter. Conversely, insertion of S between Ste2 and P in an external fusion sharply reduced beta la secretion. Complementary information about both cytoplasmic and external domains of Ste2 was therefore provided, and most aspects of the predicted topology were confirmed. The steady-state levels of beta la detected were low, presumably because of efficient degradation of the fusions in the secretory pathway; levels, however, were easily detectable. This method should be valuable in the analysis of in vivo topologies of both homologous and foreign plasma membrane proteins expressed in yeast cells.

Olfactory deficits and sleep disturbances in Parkinson's disease: a case-control survey.

BACKGROUND: Olfactory and sleep disturbances are common in Parkinson's disease, and may be early disease indicators. OBJECTIVE: To obtain information about olfactory and sleep deficits preceding the onset of motor symptoms in Parkinson's disease. SUBJECTS: 38 community dwelling patients with Parkinson's disease (73% response rate) and 32 age matched controls (60% response rate). METHODS: Using a questionnaire survey, the frequencies, timing, and relations between olfactory and sleep disturbances, drug treatment, mood, and motor deficits in Parkinson's disease were compared with those in age matched controls. Reliability of information was validated by informant interview in 9% of the sample. Interdependency of factors was assessed using Fisher's fourfold table test, and differences between populations were analysed using chi(2) and unpaired t tests. RESULTS: Microsmia was reported by 26 patients (68%) (and only one control), on average within a year of the diagnosis of Parkinson's disease. More patients than controls had excessive daytime somnolence (45% v 6%), restless legs (50% v 19%), and abnormal movements during sleep (34% v 0%), which generally occurred three to five years after diagnosis and were independent of mood disorders and drug treatment. CONCLUSIONS: Many patients with Parkinson's disease have microsmia at the onset of motor deficits, but some sleep disorders are a subsequent occurrence.

Social anxiety in childhood: the relationship with self and observer rated social skills.

BACKGROUND: Social anxiety of childhood is a common and pervasive problem. Traditional approaches to treating these difficulties have focused on providing afflicted children with social skills training. This approach has met with some, but not complete success. Recent reconceptualisations of social anxiety in the adult literature have emphasised the role of negative cognition regarding one's own social skills. Experimental evidence has demonstrated that a misperception of social skills, rather than a skills deficit per se, may be most pertinent to the understanding of social anxiety. This study set out to examine the relationship between self and observer ratings of social skill, and social anxiety in children. METHOD: One hundred and ten non-referred schoolchildren aged 8-11 years were asked to give a two-minute speech to a video camera, after which they were asked to rate their performance on a number of social skill dimensions. Neutral observers also watched the videos and rated each child on the same dimensions. RESULTS: There was very little correlation between social anxiety level and observer ratings of children's social skills. Indeed, some very anxious children achieved high observer rated social skill scores. State socially anxious children self-reported that their social skills were poorer than less anxious children. However, other than looking more nervous than less anxious children, the social skills of the high anxious children were indistinguishable from those of their less anxious peers. CONCLUSIONS: Socially anxious children may not necessarily lack social skills. Rather, their deficits may relate to nervousness and appraisals of their skills. Treatment programmes for these children should take care to assess social skills carefully before prescribing social skill remediation, and should consider employing a cognitive element to tackle negative misperceptions of subjective social skill.

Chronic lymphocytic leukaemia: case control epidemiological study in Yorkshire.

This is the second report of a large case control study of lymphoma/leukaemia occurring in Yorkshire during 1979-84, and deals with chronic lymphocytic leukaemia presenting either in its haematological (CLL) or more solid lymphomatous (malignant lymphoma-lymphocytic or MLL) forms. In all, 330 cases and 561 controls were interviewed. The results support the concept that CLL/MLL is a condition of multiple aetiologies with evidence for genetic predisposition through an excess of family cases, immune perturbation demonstrated by excessive previous skin diseases and phenylbutazone use, and viral involvement shown by links with infectious diseases and multiple sclerosis.

PCR-single-stranded confirmational polymorphism analysis for non-culture-based subtyping of meningococcal strains in clinical specimens.

Subspecific typing of clinical meningococcal strains is important in the investigation of outbreaks and for disease surveillance. Serogrouping, typing, and subtyping of strains currently require isolation of a meningococcus from one or more clinical specimens. However, the increasing widespread practice of preadmission administration of parenteral antibiotics has resulted in a decrease in the frequency of positive cultures obtained from blood and cerebrospinal fluid. Confirmation of meningococcal disease can be obtained by meningococcus-specific PCR from both cerebrospinal fluid (H. Ni et al., Lancet 340:1432-1434, 1992) and peripheral blood (J. Newcombe et al., J. Clin. Microbiol. 34:1637-1640, 1996) specimens. However, current PCR protocols do not yield epidemiologically useful typing information. We report here the use of PCR-single-stranded confirmational polymorphism (PCR-SSCP) analysis to amplify and type meningococcal DNA present in clinical specimens. PCR-SSCP analysis with the VR1 region of the Neisseria meningitidis porA gene as the target produced unique banding patterns for each serosubtype. Direct PCR-SSCP of clinical specimens can therefore provide typing data that can be used to investigate the epidemiology of clusters of cases and outbreaks and for disease surveillance in situations in which culture of patient specimens proves negative.
