Abstract
The relationship between family pesticide use and childhood brain cancer was examined in a case-control study. Telephone interviews were conducted from June 1989 through March 1990 with the natural mothers of 45 childhood brain cancer cases, 85 friend controls, and 108 cancer controls. In comparisons to friend controls, significant positive associations were observed for use of pesticides to control nuisance pests in the home, no-pest-strips in the home, pesticides to control termites, Kwell shampoo, flea collars on pets, diazinon in the garden or orchard, and herbicides to control weeds in the yard. In comparisons to cancer controls, significant positive associations were observed for use of pesticide bombs in the home, pesticides to control termites, flea collars on pets, insecticides in the garden or orchard, carbaryl in the garden or orchard, and herbicides to control weeds in the yard. In general, positive associations in comparisons to one control group were supported by elevated odds ratios in comparisons to the other control group. Several potentially important associations were identified in this study. However, small sample sizes, potential recall bias, multiple comparisons, and lack of detailed exposure verification require further research to confirm these findings.

Abstract
Human immunoglobulin G4 (IgG4) exists in two molecular forms due to the heterogeneity of the inter-heavy chain disulphide bridges in the hinge region in a proportion of secreted human IgG4. This heterogeneity is only revealed under denaturing, non-reducing conditions in which an HL "half antibody" is detected, a phenomenon not seen in other human IgG isotypes. In native conditions noncovalent interactions hold the antibody together as the H2L2 tetramer. Analysis of the hinge sequences of human IgG heavy chains suggested that the presence of serine at residue 241 might be the cause of this heterogeneity. We therefore changed the serine at 241 to proline (found at that position in IgG1 and IgG2) in a mouse/human chimeric heavy chain. This single residue substitution leads to the production of a homogeneous antibody. Further, the variant IgG4 has significantly extended serum half-life and shows an improved tissue distribution compared to the original chimeric IgG4.

Abstract
In order to define the differential bacteriology in adenoid disease, adenoids were obtained from 10 children with adenoid hypertrophy and 29 children with chronic adenoiditis. The patients' ages ranged from 18 months to 13 years. After removal of the adenoids, the surface organisms were destroyed by alcohol and flame disinfection. One gram of tissue was sampled for aerobic and anaerobic culture. There was an average of 4.8 isolates per specimen, with 4.2 aerobes and 0.6 anaerobes. The most common isolates were: Haemophilus influenzae (84%), diphtheroids (66%), non-pathogenic Neisseria species (66%), alpha-hemolytic streptococci (64%) and non-hemolytic streptococci (59%). Anaerobes were present in 56% of all cases. The distribution of organisms was similar, regardless of clinical diagnosis. Only eight (21%) of the 39 cases had 'significant' (> or = 10(5) organisms/gm) colony counts. Our study detected no difference in either organism distribution or in total colony counts in chronic adenoiditis vs. adenoid hypertrophy.

Abstract
Over 19 weeks, 104 male patients attending a genitourinary medicine clinic with gonococcal urethritis were asked to complete a questionnaire detailing symptoms. Sixty-seven questionnaires were duly completed. The examining nurse documented signs. Ninety-one isolates of Neisseria gonorrhoeae were serogrouped and auxotyped, 55 of these were from patients who had completed a questionnaire. Patients presented earlier if they had a past history of gonorrhoea (p = 0.02). The serogroup of N. gonorrhoeae did not influence the amount of discharge, the presence of meatal inflammation, dysuria or penile tip irritation or the delay in presentation after appearance of discharge. Auxotype AHU was not associated with asymptomatic gonorrhoea.

Abstract
The effect of corticotropin-releasing hormone (CRH), independent of adrenocorticotropin hormone (ACTH), was evaluated in nine healthy individuals. Cortisol release and corresponding ACTH production were determined after separate intravenous administration of ovine-CRH (1 micrograms/kg BW) and insulin inducing hypoglycemia (0.1 u/kg BW). Adrenocorticotropin hormone (1-24; 250 micrograms intravenous bolus) revealed an adequate adrenal reserve capacity in all subjects. At the time of peak cortisol response following CRH and insulin administration, IR-cortisol increments were 14 +/- 1 micrograms/dl and 9 +/- 1 micrograms/dl (mean +/- SE), respectively (p less than .05); whereas ACTH (IR-ACTH) increments were 40 +/- 10 ng/l and 53 +/- 14 ng/l, respectively. The cortisol increment/ACTH increment ratios were 0.53 +/- 0.09 and 0/36 +/- 0.09, respectively (p less than 0.05), suggesting an ACTH-independent effect of CRH on cortisol production. The authors speculate that CRH may have a direct effect on the human adrenal gland or it may release ACTH-like factors that stimulate the human adrenal cortex.

Abstract
A 24-year-old West Indian woman with a four-year history of systemic lupus erythematosus presented with progressive dypsnoea due to primary pulmonary hypertension. Despite showing a response to vasodilators, these failed to control the condition. Her pulmonary hypertension increased in severity, eventually resulting in her death. We believe primary pulmonary hypertension to be an unusual complication of systemic lupus erythematosus. We suggest that this diagnosis should be considered in all patients with systemic lupus erythematosus and progressive dypsnoea, as optimum benefit can only be obtained by early institution of vasodilator therapy.

Abstract
Wegener's granulomatosis can be a difficult diagnosis to establish. It is not uncommon to require repeated biopsies over many months for histologic confirmation. A recently developed seromarker--anti-neutrophil cytoplasm antibody--ANCA (synonymous with anticytoplasmic autoantibody--ACPA) adds a new and valuable tool for diagnosis. The literature shows this to be a highly specific and sensitive test for Wegener's granulomatosis.

Abstract
High level tetracycline resistant strains of Neisseria gonorrhoeae (TRNG) have been shown to carry a 40.6 kb (25.2 MDa) conjugative plasmid with a Class M tetracycline resistance determinant. Restriction endonuclease analysis mapping showed that there were at least two different TRNG plasmid types which were found in geographically distinct locations. The physical maps of these two plasmids were compared to a gonococcal conjugative plasmid which did not encode tetracycline resistance. The plasmid type which is endemic in the Netherlands was found to be closely related to the gonococcal conjugative plasmid, which supports the established hypothesis that the 40.6 kb plasmid has evolved by transposition of the TetM determinant into the conjugative plasmid. The plasmid found in the United States has either evolved by substantial divergent evolution or it results from a different transposition event. In the UK there have been isolations of TRNGs carrying either of the two plasmid types reflecting a flow of people both across the Atlantic and in Europe. It is possible that further TetM-containing plasmids will be found in N. gonorrhoeae paralleling the family of TEM beta-lactamase encoding plasmids already described.

Abstract
Bryostatin 1 is a macrocyclic lactone protein kinase C (PK-C) activator which has demonstrated promising antileukemic activity in preclinical studies. We have examined the effect of this agent on the metabolism and cytotoxicity of 1-beta-D-arabinofuranosylcytosine (ara-C) in both log phase and high-density human promyelocytic leukemia cells (HL-60). Exposure of low-density cells to 12.5 nM bryostatin 1 for 24 hr prior to a 4-hr incubation with 1 or 10 microM ara-C resulted in nearly a 2-fold increase in ara-CTP formation. When cells were maintained under high-cell density conditions (e.g. 5 x 10(6) cells/mL) for 24 hr prior to ara-C exposure, a 90% reduction in ara-CTP formation and ara-C DNA incorporation was observed. However, coincubation of high-density cells with bryostatin 1 for 24 hr increased ara-CTP formation 6- to 8-fold, yielding levels essentially equivalent to those achieved in low-density cells. Smaller (but still significant) increases in ara-C DNA incorporation were also noted. Enhancement of ara-CTP formation by bryostatin 1 occurred over a broad ara-C concentration range (0.1 to 100 microM), involved a temperature-dependent process, could not be mimicked by addition of hematopoietic growth factors, and was not related to neutralization of toxic or inhibitory substances in high-density medium. Exposure of cells to bryostatin 1 did not lead to morphologic or functional evidence of HL-60 cell maturation or an increase in cell viability, but did produce a decline in cellular proliferative activity as determined by thymidine and bromodeoxyuridine incorporation and cytofluorometric analysis. Bryostatin 1 did not exert its effects in high-density cells by inhibiting ara-C deamination or by interfering with ara-CTP dephosphorylation, but instead appeared to act by enhancing ara-C phosphorylation. Although cell-free extracts obtained from high-density cells exposed to bryostatin 1 exhibited levels of deoxycytidine kinase activity compared to controls, treated cells did display a significant decline in intracellular dCTP levels (e.g. 0.7 vs 1.3 pmol/10(6)), and nearly a 2-fold increase in ATP and UTP concentrations. Ara-CTP formation was also increased substantially by other PK-C activators including phorbol dibutyrate and mezerein (10-100 nM); this process was inhibited more than 70% by the PK-C inhibitor H-7 (50 microM), but not by the PK-C inhibitors staurosporine, tamoxifen, and HA1004. Finally, coadministration of ara-C and bryostatin 1 resulted in greater than expected inhibitory effects toward HL-60 cell clonogenic growth.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
A rapid enzyme activity strip test (Neisstrip, Lab M Ltd, Bury) was compared retrospectively with Phadebact Monoclonal GC coagglutination (Pharmacia Diagnostics, Uppsala, Sweden), cystine trypticase agar sugar utilisation (CTA), and Gonochek II (J W Turner, Liverpool) enzyme methods for identification of 95 Neisseria spp and related species. These had been previously identified using standard methods and included 29 that had given aberrant results. Neisstrip identified correctly all but two, including nine incorrectly identified by Phadebact and 18 erroneously identified using CTA sugars. Results were similar to those obtained with Gonochek II. After this a prospective study was performed testing 400 oxidase positive isolates derived from clinical samples cultured on gonococcal selective medium. Two organisms, both Moraxella spp, were incorrectly identified as N gonorrhoeae by the Neisstrip. The superoxol test, when used with either the Phadebact or Neisstrip tests, maintained 100% sensitivity and specificity. The Neisstrip is a rapid, economic test that is accurate and easy to interpret. It may be used alone or in conjunction with a superoxol test or a coagglutination test, which is relatively accurate but more expensive, and found by some technical staff to be more difficult to interpret.

Abstract
During 1989 and 1990 strains of Neisseria gonorrhoeae with reduced susceptibility to ciprofloxacin were isolated in laboratories across the United Kingdom. Treatment failures were associated with some of these infections. These strains were detected by quantitative susceptibility testing because the zone of inhibition around 5 micrograms ciprofloxacin discs shows little decrease in size even with those that are the most resistant. This study determined that strains with reduced susceptibility to ciprofloxacin (MIC of greater than or equal to 0.05 mg/l) produced no zone of inhibition around a commercially available disc containing 30 micrograms of nalidixic acid. Ciprofloxacin sensitive (MIC of less than 0.05 mg/l) strains, however, grew with a large zone (greater than 21 mm) around this disc. These observations suggest that laboratories could adopt this disc test to detect those strains for which ciprofloxacin is not appropriate treatment.

Abstract
In a 2-year study of false-positive anti-HIV-1 tests in blood donors at Manchester and Lancaster Blood Banks, the reactions associated with a HIV-infected cell lysate antigen were compared with those using recombinant-antigen-based tests. In year 1 (cell lysate test) at Manchester BTS 0.21% of 119.178 donations were repeatedly reactive, compared with 0.53% of 119,004 donations in year 2 (recombinant antigen). Reactive sera were tested at Manchester PHL by three different immunoassays. Referred specimens were classified as anti-HIV positive (95-100% reactive in all the assays), equivocal or negative (negative results in all three immunoassays). Two donors were confirmed to be anti-HIV positive over the 2-year period. Most sera were negative by confirmatory immunoassays in years 1 and 2. In year 1, a study of 60 referred sera with sex- and age-matched controls showed high correlation between a reactive anti-HIV-1 screening test and indeterminate anti-HIV-1 patterns on Western blot showing reactions with HIV gag-coded proteins. In year 2, less than 10% of referred sera were reactive by Western blot, and there was no correlation between a reactive screening anti-HIV test, the strength of signal in the test or a reactive Western blot. Follow-up showed that donors whose sera were reactive in years 1 and 2 by the anti-HIV-1 screening test formed almost two different populations. Four donors with equivocal anti-HIV-1 confirmatory tests had anti-HIV 'envelope' reactions.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
There is concern that the impaired cell mediated immunity caused by the human immunodeficiency virus may increase the risk of severity of Plasmodium falciparum infection and could lead eventually to a decreased response to standard antimalarial treatment. In 1986, at Mama Yemo Hospital, Kinshasa, Zaire, the incidence of malaria was determined in a cohort of 59 patients who had recently acquired HIV-I infection through blood transfusion and in a cohort of 83 HIV-I seronegative controls who were recipients of HIV-I seronegative blood. All cohort patients were asked to visit the study physician whenever they developed fever. On each of these occasions thick film was examined for the presence of malarial parasites. HIV-I seropositive patients presented more often with episodes of fever per person month observation than HIV-I seronegative patients (P = 0.003). The total number of positive thick films per person months observation was significantly higher among HIV-I seropositive patients than among the HIV-I seronegative ones, but percentages of positive thick films per episode of fever were the same in both groups (46%). During a 5 month period, cohort patients presenting with a moderate attack of malaria were treated with oral quinine 20 mg/kg daily in two doses for 5 days. Twenty-three (92%) of 25 HIV-I seropositive patients and 28 (82%) of 34 HIV-I seronegative patients had a negative film 7 days after starting treatment. This study suggests that there seems to be no direct interaction of major clinical importance between HIV infection and malaria.

Abstract
Parathyroid cysts are relatively uncommon lesions. Approximately 200 cases have been reported. Despite their location in the region of the thyroid gland, they have not previously been discussed in the otolaryngologic literature. They arise from remnants of the pharyngeal pouch or as a result of cystic degeneration of a parathyroid adenoma. A case of a parathyroid cyst occurring in a 13-year-old female is presented. This is the youngest case ever reported. Fine needle aspiration of an anterior neck mass yielded clear fluid, a finding highly suggestive of a parathyroid cyst. Radioimmunoassay of the fluid demonstrated a high level of parathormone and low level of thyroglobulin concentration, thereby confirming the diagnosis. In this case, which was diagnosed by FNA, the need for a trial of thyroid hormone suppression or hemithyroidectomy was obviated.

Abstract
Between January and April 1987, 97 of 302 (32%) children attending a primary school in Bury, Lancashire, were affected by an exanthematous illness. The duration and extent of the episode caused considerable local interest and anxiety. Examination of 6 serum specimens obtained during the subsequent investigation demonstrated evidence of recent Human Parvovirus B19 infection in 3 children and 1 teacher. No evidence of recent rubella virus infection was found. The investigation of the episode is discussed in the context of problems which may occur in the management of similar outbreaks.
