Abstract
INTRODUCTION The treat-to-target serum uric acid approach is recommended in local and international guidelines on gout management. Instruction for initiation and dose escalation for urate lowering therapy may cause confusion to the patient. Our aim was to develop and validate Gout Treat-To- Target booklet to aid in patient education. MATERIALS AND METHODS A content development team which consisted of three consultant rheumatologists developed the booklet. Content validation was performed by a panel of evaluators consisted of eleven physicians (four consultant rheumatologists, two clinical specialists, and five medical officers), who were involved in gout management. Face validation was performed by ten patients with gout. RESULTS Item-Content Validity Index ranged from 0.9 to 1 with regards to relevancy, clarity, ambiguity and simplicity. Side effects of uricosuric agents were added to the draft based on an evaluator's comment. Item-Face Validity Index was 1, which indicated that all patients were in 100% agreement with all items. CONCLUSION We developed and validated our Gout Treat-to- Target booklet. There was high agreement in I-FVI and I-CVI among physicians and patients.

Abstract
BACKGROUND COVID-19 has the potential to affect the mental health of health care workers (HCWs). It is known that HCWs who serve as front-liners during the COVID-19 pandemic experience stress and have the fear of contracting the infection. Little is known of how being a positive contact affects HCWs. OBJECTIVE We examined the experience of HCWs who were quarantined following a close unprotected contact with a COVID-19 positive colleague and explore the psychological impact especially as the timing of the quarantine coincided with the Eid (annual Muslim festival) celebration in Malaysia. METHODS This was a cross-sectional on-line questionnaire study, involving HCWs exposed to a COVID-19 positive colleague in Universiti Kebangsaan Malaysia Medical Centre, a teaching hospital. Data on demographics, levels of depression, anxiety and stress using a validated depression, anxiety, and stress scale (DASS-21) questionnaire, aspects of quarantine, wearing of masks, hand hygiene practice and swab experience were collected. RESULTS Twenty-two HCWs participated. Eighteen (81.8%) were between 30-39 years and 17 (77.3%) were women. Majority 19 (86.3%) were Malays. There were twelve (54.5%) medical officers, 5 (22.7%) specialists and 5(22.7%) allied health staff. Eighteen out of 22 (81.8%) felt they were able to do home quarantine adequately. All tested negative with a mean (Standard Deviation) hour of contact of 2.56±2.38 hours. Eighteen reported their biggest concern was infecting their families. CONCLUSION HCWs undergoing contact swabbing and quarantine are vulnerable to depression, anxiety and stress. The ability of the HCW to adequately home quarantine should not be taken for granted. Psychological support should be offered to HCWs who are positive contacts.

Abstract
BACKGROUND AND OBJECTIVE Coronavirus Disease 2019 (COVID- 19) was first reported in Malaysia in March 2020. We describe here the clinical characteristics and computed tomography (CT) patterns in asymptomatic young patients who had laboratory-confirmed COVID-19. METHODS This is a retrospective observational study where 25 male in-patients with laboratory-confirmed COVID-19 in Hospital Canselor Tuanku Muhriz. Demographics, clinical data and CT images of these patients were reviewed by 2 senior radiologists. RESULTS In total there were 25 patients (all males; mean age [±SD], 21.64±2.40 years; range, 18-27 years). Patients with abnormal chest CT showed a relatively low normal absolute lymphocytes count (median: 2.2 x 109/L) and absolute monocyte count (median: 0.5 x 109/L). Lactate dehydrogenase was elevated in 5 (20%) of the patients. The procalcitonin level was normal while elevated levels of alanine aminotransferase, total bilirubin, platelet and C-reactive protein were common. Baseline chest CT showed abnormalities in 6 patients. The distribution of the lesions were; upper lobe 3 (12%) lower lobe 3 (12%) with peripheral distribution 4 (16%). Of the 25 patients included, 4 (16%) had ground glass opacification (GGO), 1 (4%) had a small peripheral subpleural nodule, and 1 (4%) had a dense solitary granuloma. Four patients had typical CT features of COVID-19. CONCLUSION We found that the CT imaging showed peripheral GGO in our patients. They remained clinically stable with no deterioration of their respiratory symptoms suggesting stability in lung involvement. We postulate that rapid changes in CT imaging may not be present in young, asymptomatic, non-smoking COVID-19 patients. Thus the use of CT thoraxfor early diagnosis may be reserved for patients in the older agegroups, and not in younger patients.

Abstract
Vascular access catheters such as Tesio-Caths are preferentially inserted in the internal jugular vein and serve as access for hemodialysis. Complications related to the removal of these types of lines are uncommon. We report four patients in whom the tip of the Tesio-Cath broke and was left stuck in the superior vena cava. Although there is no defined limit to the maximum length of stay of vascular access catheters for dialysis, the possibility of catheter entrapment should be considered. It remains to be determined whether removing Tesio-Caths every 16–18 months is beneficial in avoiding this complication.

Abstract
The aim of the present study was to assess the hypoglycaemia risk and safety of dapagliflozin compared with sulphonylurea during the fasting month of Ramadan. In this 12-week, randomized, open-label, two-arm parallel group study, 110 patients with type 2 diabetes who were receiving sulphonylurea and metformin were randomized either to receive 10 mg (n = 58) of dapagliflozin daily or to continue receiving sulphonylurea (n = 52). The primary outcome was to compare the effects of dapagliflozin and sulphonylurea on the proportions of patients with at least one episode of hypoglycaemia during Ramadan, as well as to assess the safety of dapagliflozin when used to treat patients observing Ramadan. A lower proportion of patients had reported or documented hypoglycaemia in the dapagliflozin group than in the sulphonylurea group: 4 (6.9%) versus 15 (28.8%); p = 0.002. The relative risk of any reported or documented hypoglycaemia in the 4th week of Ramadan was significantly lower in the dapagliflozin group: RR=0.24, 95%CI: 0.09, 0.68; p=0.002. No significance differences were observed between the two groups regarding postural hypotension (13.8 vs 3.8%; p = 0.210) or urinary tract infections (10.3 vs 3.8%; p = 0.277). In conclusion, fewer patients exhibited hypoglycaemia in the dapagliflozin group than in the sulphonylurea group.

Abstract
The presence of antiphospholipid antibodies (aPLs) is closely associated with thrombotic events and pregnancy complications such as recurrent pregnancy loss, preeclampsia and placental insufficiency. We investigated the presence of aPLs and its frequency among female patients with a history of fetal loss in a Malaysia population. Serum samples were collected from 108 patients who had (1) one or more unexplained deaths of morphologically normal fetuses at or beyond the 22nd week of gestation, or (2) one or more premature births of morphologically normal neonates at or before the 24th week of gestation due to eclampsia or preeclampsia, or recognized features of placental insufficiency, or (3) three or more unexplained, consecutive, spontaneous miscarriages before the 20th week of gestation. Serum was tested for aPLs subtypes: anticardiolipin (aCL), anti-beta-2- glycoprotein I (aβ2GPI), anti-beta-2-glycoprotein I dependent cardiolipin (aβ2GPI dependent CL), anti-phosphatidylcholine (aPC), anti-phosphatidylethanolamine (aPE), anti-phosphatidylinositol (aPI), anti-phosphatidylserine (aPS) and anti-sphingomyeline (aSph) by using the enzyme-linked immunosorbent assay (ELISA) method. The mean age of patients was 30±5. Four patients (3.7%) were found positive for at least one aPLs subtype. Four aPLs subtypes were detected. The most common subtypes was aβ2GPI dependent CL (3.7%), followed by aCL (2.7%), aβ2GPI (0.9%), and aPE(0.9%). In conclusion, frequency of aPLs among women with fetal loss (3.7%) in Malaysia was low with subtype aβ2GPI dependent CL being the most prevalent aPLs.

Abstract
AIM The prevalence of diabetes mellitus among Malaysians aged ≥ 30 years of age has increased by more than twofold over a 20-year period. This study aimed to determine the current status and to evaluate the diagnostic usefulness of the HbA(1c) cut-off point of 48 mmol/mol (6.5%). METHODS Using a two-stage stratified sampling design, participants aged ≥ 18 years were recruited from five zones selected to represent Malaysia. An oral glucose tolerance test was performed on all those not known to have diabetes. RESULTS A total of 4341 subjects were recruited. By World Health Organization criteria, the prevalence of diabetes mellitus was 22.9%; of that percentage, 10.8% was known diabetes and 12.1% was newly diagnosed diabetes. Diabetes was most prevalent amongst Indians (37.9%) and Malays (23.8%). Prevalence of new diabetes mellitus was only 5.5% (95% CI 4.9-6.3) when based on the HbA(1c) diagnostic criteria of 48 mmol/mol (6.5%) and, although the cut-off point was highly specific (98.1%), it was less sensitive (36.7%) compared with 45 mmol/mol (6.3%), which showed the optimal sum of sensitivity (42.5%) and specificity (97.4%) in identifying new diabetes mellitus. CONCLUSION This study recorded an overall diabetes prevalence of 22.6%, almost a twofold increase from 11.6% reported in 2006. This was likely attributable to the higher prevalence of new diabetes (12.1%) diagnosed following an oral glucose tolerance test. An HbA(1c) of 45 mmol/mol (6.3%) was found to be a better predictive cut-off point for detecting new diabetes in our multi-ethnic population.

Abstract
AIMS Cardiovascular disease is the foremost cause of mortality in Malaysia but little is known about the prevalence of the metabolic syndrome and its associations with other known cardiovascular risk markers. We undertook a population-based study to examine these. METHODS For the study, 4341 subjects were selected using a multistage stratified sampling method. Subjects were interviewed for personal and past medical history. Biomedical markers and anthropometric indices were measured. The metabolic syndrome was defined using the harmonized criteria. The associations between the metabolic syndrome and cardiovascular risk markers, including high-sensitivity C-reactive protein, microalbuminuria and HbA(1c) were examined. RESULTS The prevalence of the metabolic syndrome was 42.5%. Subjects with the metabolic syndrome are significantly more likely to have higher BMI (> 25 kg/m(2)), HbA(1c) [≥ 42 mmol/mol (6.0%)], LDL (≥ 2.6 mmol/l), elevated albumin:creatinine ratio (> 2.5 μg/mmol creatinine for men, 3.5 μg/mmol creatinine for women) and high-sensitivity C-reactive protein (> 3 mg/l); odds ratio 5.48, 6.14, 1.44, 3.68 and 1.84, respectively, P < 0.001. The presence of an elevated albumin:creatinine ratio and high-sensitivity C-reactive protein are strong predictors for the presence of a higher number of positive criteria of the metabolic syndrome. HbA(1c) > 48 mmol/mol (6.5%) is associated with increased relative risk of elevated albumin:creatinine ratio, high-sensitivity C-reactive protein and LDL (relative risk 3.10, 2.46 and 1.65 respectively, P < 0.001). CONCLUSIONS We confirmed the high prevalence of the metabolic syndrome in Malaysia. Our study revealed a strong relationship between risk markers of elevated BMI, HbA(1c), LDL, albumin:creatinine ratio and high-sensitivity C-reactive protein with the presence of the metabolic syndrome, putting them at a statistically high risk for cardiovascular mortality.

Abstract
This study was undertaken to determine the presence of thyroid autoantibodies and associated pregnancy complications from 49 pregnant women with thyroid disease. There were 31 (63%) women with Graves' disease (GD) and 18 (37%) with primary hypothyroidism (PHT). A total of 26 (53.1%) women, 19 (61%) with GD and seven (39%) with PHT, had positive antibodies. Six had thyroid peroxidase antibodies (TPO), one with thyroglobulin antibody (TG) and eight had TSH receptor antibodies (TR). Two had a mixture of antibodies involving TG/TPO (one GD vs one PHT), four with TG/TPO/TR (all had GD) and five with TPO/TR (four with GD vs one with PHT). There were associations in women with positive thyroid antibodies and pre-eclampsia (15.4%), abruptio placenta (4%), caesarean deliveries (31%), postpartum thyroiditis (19.2%) and abnormal neonatal thyroid function (15.4%). Women with positive thyroid antibodies in pregnancy need close care during and after pregnancy, as they can develop complications affecting both mother and fetus.

Abstract
AIMS To determine the relationship between HbA1c and other indices of glycaemic status derived during a standardized meal tolerance test (MTT) in newly diagnosed treatment-naive subjects with Type 2 diabetes (T2DM). METHODS T2DM subjects (n = 262) consumed a standard MTT in the morning after a 10-h overnight fast. Frequent samples for plasma glucose (PG) were collected over the 4-h test period. The relationship between HbA1c and other glycaemic indices derived from the MTT were explored. The postprandial glucose exposure was calculated as the area under the incremental plasma glucose curve above the fasting level for the test period (AUC1). Excess hyperglycaemia was calculated as the AUC0-4 h above the arbitrary PG concentrations of 6.0 mmol/l (AUC2) and 5.5 mmol/l (AUC3), respectively [upper limit of fasting normoglycaemia according to World Health Organization (WHO) and American Diabetes Association (ADA), respectively]. Fasting hyperglycaemia was also estimated, being the difference between each of the above and the postprandial excursion. The participants were divided into three subgroups according to HbA1c (Group 1, <or= 7.0%; Group 2, 7.1-9.0%; Group 3, > 9.0%) and the relative contribution calculated of the postprandial glucose and fasting hyperglycaemia to the excess hyperglycaemia above the designated international thresholds for fasting plasma glucose. RESULTS HbA1c was more strongly correlated with the fasting plasma glucose (r = 0.85, P < 0.001) than the overall postprandial glucose exposure (r = 0.539, P = 0.003). The contribution of fasting hyperglycaemia to excess hyperglycaemia using the WHO criteria for normal fasting plasma glucose for the three groups (Groups 1, 2 and 3) was 50.4%, 54.3% and 69.8%, respectively, and 57.8%, 58.8% and 71.4% using the ADA criteria. CONCLUSIONS The contribution of fasting hyperglycaemia to excess hyperglycaemia increases as glycaemic control deteriorates, becoming dominant with an HbA1c in excess of 7.0%. These findings indicate which therapeutic approach needs to be adopted based on the HbA1c of the person with T2DM.

Abstract
Castanospermine (CAST) is a known and potent inhibitor of various alpha-glucosidases in eukaryotes. In this work, we elucidated whether CAST could also be used for determining bacterial alpha-glucosidase activity, when measured with 4-methylumbelliferyl-alpha- D-glucoside as a substrate, both in a complex bacterial community, in activated sludge and in pure cultures of bacterial isolates. We found that 140 microM CAST inhibited alpha-glucosidase activity by 30% in a pure culture of Pseudomonas stutzeri. The alpha-glucosidase activity in Chryseobacterium gleum was inhibited by 90% at a concentration of 150 microM CAST, whereas the alpha-glucosidase in Paracoccus denitrificans was resistant to the inhibitor. CAST (140 microM) reduced alpha-glucosidase activity in activated sludge by 40%, the respiration rate being reduced by only 12%. No significant inhibition of the respiration rate was observed in Ps. stutzeri or Pa. denitrificans, whereas the respiration rate in C. gleum grown in a medium containing starch was inhibited by 50% with 140 microM CAST. No effect of CAST was observed in C. gleum grown in a complex medium. This indicated that CAST, at the concentration used, did not cause a general negative effect on bacterial activity. The results suggest that the CAST assay may potentially be useful in determining whether alpha-glucosidase activity, starch, poly- and disaccharides contribute appreciably to the overall activity of a bacterial community. However, the assay should not be used for quantitative measurements of such activity.

Abstract
Microbiologic evidence of urinary tract infection was studied in 447 pregnant women with (n = 149) or without (control group, n = 298) gestational diabetes mellitus after mid-pregnancy. Laboratory investigations included chemical analysis, microscopic examination and culture of a clean midstream voided urine specimen. Nineteen women (4.2%) had asymptomatic bacteriuria (7 study, 12 control, P=0.7). Of these, 7 (38%) developed symptomatic infection despite treatment with antibiotics (2 study, 5 control, P=0.7) and 6 (31%) had recurrent bacteriuria later in pregnancy (3 study, 3 control, P=0.3). Twelve more women (2.6%) had symptomatic infection (5 study, 7 control, P=0.5), 7 had acute cystitis (3 study, 4 control, P=0.5) and 5 had acute pyelonephritis (2 study, 3 control, P=0.7). Escherichia coli was the commonest pathogen, accounting for 22 (71%) infection episodes. Gestational diabetes mellitus was not associated with increased risk of urinary tract infections nor of maternal and perinatal morbidity as a result of infection.

Abstract
Enzymatic alpha-glucosidase and peptidase activity in a nitrifying trickling filter (NTF) at the Rya wastewater treatment plant, Göteborg, Sweden, was investigated to evaluate whether these activities can be used as indicators of heterotrophic activity and polymer degradation. Samples of the biofilm were taken from the NTF and incubated in sterile filtered effluent water from the NTF with the addition of soluble starch, peptone, and ammonium chloride. In order to determine the distribution of enzyme activities, the alpha-glucosidase and peptidase activities were measured in the biofilm samples, in the filtered effluent water from the NTF and in the water phase in which the biofilm was incubated. Activities of both enzymes were found both in the effluent water from the NTF and in the biofilm. The enzyme activities were elevated in the samples when starch and peptone were present. In addition, there was a significant inhibition of ammonium oxidation in samples incubated with starch and peptone. Thus, the presence of starch, peptone and ammonium resulted in increased activity of heterotrophs, which lead to an inhibition of the nitrifiers, probably via competition for available oxygen.

Abstract
Attenuated Salmonella strains are of interest as new vaccine candidates and as vectors of cloned genes of other organisms. Attenuated strains expressing specific cytokines were constructed as a means of manipulating the immune response in various disease settings. In the present study, interleukin-2 (IL-2)-expressing (GIDIL2) or tumor necrosis factor alpha (TNF-alpha)-expressing (GIDTNF) strains were compared with the parent strain (BRD509) for the effect of cytokines on anti-Salmonella immunity. Expression of IL-2 resulted in a rapid clearance of the organism soon after vaccination. The reduction in GIDIL2 CFU was 50- to 300-fold higher than that of BRD509 and correlated with a markedly decreased splenomegaly. Furthermore, no evidence for any significant activation, including upregulation of surface markers and production of nitric oxide (NO), was observed in spleens of GIDIL2-injected mice. In contrast, the host response to GIDTNF was marked by an early, strong, splenic cellular influx, but surprisingly, the degree of induced splenomegaly and NO secretion was only 50% of that observed in BRD509-treated mice. Despite this, bacterial colonization of the spleen in GIDTNF-immunized animals was either slightly decreased from or equivalent to that of the BRD509-treated group, suggesting the induction of additional antimicrobial mechanisms by TNF-alpha. In vivo protection studies demonstrated that, at limiting doses, GIDIL2 was inferior to GIDTNF and BRD509 in its capacity to protect against virulent challenge. At high doses, however, all three strains exhibited equal protective efficacy. These results demonstrate that the immune response against intracellular bacteria can be manipulated by pathogen-expressed cytokines and open the way for further fine tuning of immune responses not only to Salmonella strains themselves but also to the heterologous gene(s) carried by them.

Abstract
OBJECTIVE To evaluate the antiretroviral activity and safety of multiple escalating doses of amprenavir administered alone, and in combination with abacavir in HIV-1-infected adults. DESIGN Sixty-two HIV-1-infected subjects were enrolled in a multicentre, open-label, non-randomized, dose-escalating trial. METHODS Subjects were assigned to one of six dose groups and received amprenavir 300 mg twice daily, 300 mg three times daily, 900, 1050, or 1,200 mg twice daily for 4 weeks. One dose group received amprenavir 900 mg twice daily in combination with abacavir 300 mg twice daily for 4 weeks. Antiretroviral activity was assessed by measuring changes from baseline in plasma HIV-1 RNA levels and CD4 cell counts. Safety was evaluated by monitoring clinical adverse events and changes in laboratory values. Genotypic and phenotypic analyses were performed using ABI sequencing and the recombinant virus assay, respectively. RESULTS At week 4, amprenavir monotherapy (900, 1,050, or 1,200 mg twice daily) resulted in marked decreases in plasma HIV-1 RNA levels (1.3-1.6 log10 copies/ml), and substantial increases in CD4 cell counts in the two dose groups who received 1,050 mg twice daily (118 x 10(6) cells/mm3) or 1,200 mg twice daily (114 x 10(6) cells/mm3). Amprenavir/abacavir resulted in median plasma HIV-1 RNA reductions of 1.8 log10 copies/ml, and median CD4 cell count increases of 138 x 10(6) cells/mm3. Amprenavir was reasonably well tolerated with few treatment-limiting adverse events. No known active site mutations associated with amprenavir resistance were selected in any of the dose groups, and no significant phenotypic resistance to amprenavir developed during 4 weeks of therapy. CONCLUSIONS The antiviral effect of amprenavir monotherapy increased with escalating doses, and all amprenavir doses were reasonably well tolerated over 4 weeks of therapy. Amprenavir/abacavir combination therapy elicited a potent antiviral effect. The three highest doses of amprenavir (900, 1,050 and 1,200 mg twice daily) were selected to design subsequent Phase II and III studies that confirmed the safety profile and efficacy of amprenavir in combination regimens and led to the approval of amprenavir in the USA in 1999.

Abstract
In order to gain knowledge about the nature of group A streptococcal throat colonization of asymptomatic children, we studied a cohort of healthy children selected at random. Those with throat cultures positive for group A Streptococci (GAS) were followed for 5 weeks. Repeat throat swabs were obtained at weekly intervals for antigen detection and culture. GAS obtained were serotyped for T antigen. Twenty-two children were identified as having GAS and 50% had a positive antigen test and culture at least five times in 6 weeks. There was no consistent pattern in the typeable organisms. Most individuals had more than one T-type alternating with non-T-typeable organisms. We conclude that colonization may be a dynamic process involving numerous organism serotypes, which wax and wane.

Abstract
The immunologic and virologic efficacy and safety of interferon a (IFN-alpha) administered in combination with zidovudine (ZDV) and zalcitabine (ddC) was evaluated in HIV-infected subjects with CD4+ cell counts between 300 and 500 cells/ml and no more than 14 weeks of prior antiretroviral therapy. A total of 256 subjects enrolled in an open-label, randomized controlled trial. Subjects were randomized equally into treatment groups. All subjects received ZDV and ddC, while half also receive IFN-alpha (3 MU subcutaneously every 24 hr). At 48 weeks the median average area under the curve minus baseline (AAUCMB) for plasma HIV-1 RNA for the two-drug group was -0.68 versus -0.75 log10 copies/ml for the IFN-alpha group (p = 0.046). Mean HIV-1 RNA changes from baseline to 48 weeks for these groups were -0.65 and -1.12 log10 copies/ml, respectively (p = 0.010). The median AAUCMB for CD4+ cell count for the two-drug group was 28 versus -1 cells/mm3 for the IFN-alpha group (p = 0.011). Neutropenia, anemia, and drug intolerance were more common in the IFN-alpha group. This study demonstrates that IFN-alpha inhibits HIV-1 replication but attenuates the CD4+ cell response to dual therapy with ZDV and ddC.

Abstract
OBJECTIVE To test the value of using prophylactic antibiotics at elective cesarean delivery. METHOD One-hundred and twenty women delivered by elective cesarean in the absence of labor and before the rupture of membranes were randomized to receive either 1.5 g of cefuroxime intravenously at cord clamping (n = 59) or no prophylaxis (control group, n = 61). RESULTS Twelve women developed febrile morbidity (six study, six control, P = 0.09). Of these, five had endometritis (two study, three control, P = 0.09) and two had wound infection (one study, one control, P = 0.09). Ten more women had microbiological evidence of endometritis and wound infection (six study, four control, P = 0.08). There was no significant difference in the hospital stay (6.5 days study, 6.8 days control, P = 0.06). Staphylococcus aureus was the commonest pathogen accounting for 14 infection episodes. Amniotic fluid culture could not predict the development of infection. CONCLUSION Administration of prophylactic antibiotics at elective cesarean deliveries was not associated with decreased postoperative morbidity.

Abstract
The objective of the study was to determine the correlation between group A streptococcal antigen detected from throat swabs with the culture results. A total of 1457 children had two swabs taken simultaneously, and culture and antigen detection were performed. There was a good correlation between antigen detection and isolation rates. In all, 225 strains of group A streptococcus were isolated;53 [57.6%] were from the 92 children with high antigen positivity, 68 [55.7%] were from the 122 children with medium antigen positivity and 77 [25.4%] were from 303 children with low antigen positivity;only 27 [2.9%] were from the 940 children with no antigen detected. We postulate that those who are antigen-positive, culture-negative carry the organisms in their throats, but they may be missed on culture because of the small number carried

Abstract
Group A streptococci (GAS) are the most frequent cause of pharyngitis in children and are a common cause of emergency room or paediatric clinic visits worldwide. This study determined the representative M and T types of GAS, and their distribution, among schoolchildren in the United Arab Emirates. Throat swabs were taken and cultured for GAS isolates during the winter of 1994-95 from 1000 children aged 5-7 years attending nine schools. Of the isolates obtained, 100 were serotyped using standard techniques. Nearly all these isolates (91%) were T typable, falling into 15 T types; the commonest being type 1 (n = 17), type 6 (n = 15), type 11 (n = 10), type 2 (n = 8), type 12 (n = 8), and type 28 (n = 8). A total of 76% of the isolates were typable for M protein, falling into 14 M types, with type 1 (n = 17), type 6 (n = 15), type 2 (n = 8), type 22 (n = 5), type 28 (n = 7), and type 75 (n = 5) predominating. Serotype clusters were found in certain classes or schools, although the number of isolates examined was too small to allow definitive epidemiological conclusions to be drawn. The ease of serotyping these isolates suggests that GAS strains in the United Arab Emirates are similar, but not necessarily related, to those commonly found in the USA and Europe, and that these may be the most prevalent strains worldwide. The relative prevalence of M type 1 is significant, as this GAS serotype is associated with serious diseases such as rheumatic heart disease, a recognized problem in the United Arab Emirates, and toxic shock syndrome, which has not yet been reported from this area. Knowledge of the prevalence of GAS serotypes, and further research on the epidemiology of streptococcal disease, will be useful should streptococcal vaccines become available.

Abstract
The aim of this study was to establish the carrier rate of group A beta haemolytic streptococci in school children in Al Ain, United Arab Emirates. One thousand and two randomly selected school children aged 5-7 years had their throats swabbed twice for both culture and direct antigen detection of group A streptococci. One hundred and fourteen children (11.3%) had both a positive antigen and culture test, while 216 (21.6%) had antigen-positive tests only and 16 (1.5%) had a positive culture only. Thus, the combination of culture and antigen detection revealed a carrier rate of 35.4% in the children examined. We conclude that in an affluent but isolated desert area on the Tropic of Cancer, group A streptococcal carriage rate is high. Antigen detection is superior to culture techniques in asymptomatic carrier studies.

Abstract
A 1-year study was conducted on 151 patients with finger- or toenail disease attending a dermatology clinic in Al Ain, United Arab Emirates. Nail scrapings and or clippings were collected and investigated with a KOH preparation for direct microscopy and cultured for fungi. Eighty-nine (59%) patients were females. Most females (62%) presented with fingernail disease while in men the toenails were involved in 76%. Fungi were isolated in 78 (52%) of all cases and the fingernails were more commonly positive than toenails. Of the 78 isolates, 49 (63%) were yeasts, including eight Candida species, dermatophytes accounted for 22 (28%) and seven (9%) were other moulds. Non-dermatophyte moulds constituted 20% of male isolates but only 4% of female isolates. Eighty-one per cent of Candida species were from fingernails, while 87% of all the dermatophytes were from toenails.

Abstract
The responses to sorption treatment have been analysed for 373 patients suffering from staphylococcal, allergic, purulent, polypous-purulent rhinosinusitis. For enterosorption a coal spherical phi EH sorbent was used. Application sorption was performed with fabric sorbent AYT-M2, nonfabric sorbent AHM-pi, dust phi EH sorbent. Gelevin was tried for tampon-free postoperative management after dissection of the paranasal sinuses. Sorbents application advances the efficacy of nasal and paranasal disease treatment.
