This study sought to examine whether the administration of quinfamide at 3- or 6-month intervals diminished the frequency ofEntamoeba histolyticacysts in stool samples compared to controls. The prospective, longitudinal, randomized, single-blind study examined children from six primary schools in Celaya and Neutla, Guanajuato. Of the 1,524 students in these schools, we selected participants for the study as follows: Children were included in the study if their parents agreed in writing to the study and if the children demonstrated evidence ofE. histolyticacysts after a parasitoscopic analysis by concentration (PSC) in three samples over consecutive days using Faust’s method. Those included in the study received a single 4.3-g/kg dose of quinfamide, and we performed PSC on days 5, 6, and 7 following dose administration to examine whether quinfamide had affected the presence of the cysts. The study participants who tested negative for cysts were divided into three groups: Group 1 had 102 patients who underwent quinfamide treatment and three CPS analyses after the 12 months of the study; Group 2 had 98 subjects who underwent the quinfamide treatment and three CPS analyses at months 3, 6, 9, and 12 after their entrance into the study; and Group 3 had 102 patients, who underwent the quinfamide treatment and series of three CPS analyses at months 6 and 12 of the study. All participants received the dose of quinfamide after providing stool samples and after a clinical gastrointestinal history was obtained. Further clinical gastrointestinal data were collected 5 days after the quintamide dose was administered. We used EpiInfo 6.0 for statistical analysis, calculatingX2andpvalues for the clinical data and the CPS data after the 12 months concluded. Of the initial samples of 1,524 subjects, 308 (20.2%) had Entamoebic cysts. Of these, six were further eliminated because they did not meet the inclusion requirements. At the conclusion of the study, Group 1 presented with 37.6% of subjects still testing positive for cysts; of Group 2, 12.5% tested positive; and in Group 3, 23.5% of participants tested positive for cysts (X2= 16.8; df = 2;p= 0.0002). For comparisons of groups 1 and 2 and 1 and 3,p> 0.05. We conclude that antiamoebic chemoprophylaxis can be a choice for control of amoebic infection where personal hygiene and food consumption habits are not improving.

Objectives: 1) To evaluate the overall prevalence rate of viral hepatitiscarrier state among a group of voluntary blood donors. 2) To find the proportion of anti HCV in the study group. 3) Tofind the probable mode of transmission of HCV infection in the study group. Setting: Pathology lab, Jinnah Hospital,Iqra Medical Complex & Hi Tech Lab, Lahore. Period: November 2000 to April 2001. Patients & Methods: A total of890 apparently healthy blood donors (797 males, 93 females) were studied. Clinical details were recorded. The bloodsamples were collected using packed sterile disposable syringes. Sera were analysed by a qualitative enzymeimmunoassy sera diagnostic test using second generation ELISA Kits. Results: Among 890 subjects screened, carrierstate for hepatitis-C was 6.06%. The prevalence of hepatitis-C amongst total cases positive for hepatitis was 33.5%.A higher prevalence rate in males (6~8%) was observed as compared to females (2.22%). The difference wasstatistically significant (p<0.05). The most important mode of transmission was through injections; (males 32.075%,females 100%) followed by blood transfusion. Only 5.88% of the cases had an episode of jaundice in the past.Conclusion: A remarkable positive cases of hepatitis C in this study underline the dire need of comprehensive planfor multi-disciplinary approach for HCV prevention and control.

The Mean

The purpose of the study was to evaluate central corneal thickness in diabetic patients and to compare the results with controls without diabetes mellitus. Sixty-five diabetic patients (65 eyes) constituted the study group, and 50 eyes were from the healthy control group (50 non-diabetic patients). The study group was subdivided into group 1 (no diabetic retinopathy, n = 35), group 2 (mild to moderate nonproliferative diabetic retinopathy, n = 20), and group 3 (proliferative diabetic retinopathy, n = 10). Central corneal thickness measurements in microns were determined using ultrasound pachymetry. The mean central corneal thickness was significantly greater in the study group (567.14 μm ± 14.63 μm) than in the control group (531.14 μm ± 5 μm). In addition, the mean central corneal thickness was found to be greater in group 3 (577 μm ± 12 μm) than in groups 1 (562 μm ± 13 μm) and 2 (566.86 μm ± 15 μm), but the difference did not reach statistical significance. We found that the mean central corneal thickness for diabetic patients was thicker than that of the healthy controls. Thicker central corneas associated with diabetes mellitus should be taken into consideration when obtaining accurate intraocular pressure measurements in diabetics.

Background: Glucose tolerance testing in pregnancy identifies many women with glycaemic responses that exceed normal range but that do not meet the threshold required to diagnose Gestational Diabetes Mellitus. It is controversial whether maternal hyperglycemia less severe than in diabetes is associated with increased risk of adverse pregnancy outcome or not. Materials and methods: All women were subjected to Glucose Challenge Test(GCT) with 50 gram glucose either at first visit or between 24-28 weeks on the basis of risk profile. High risk cases were screened at first visit and the rest between 24-28 weeks. Patients with a GCT value ≥200mg/dl were not subjected for GTT and were diagnosed as GDM.Value of GCT <140 mg/dl was taken as normal. Irrespective of GCT result, women were subjected to Oral Glucose Tolerance Test (OGTT) as recommended by WHO with 75 gram glucose using WHO criteria. Study group was identified with 4 categories with abnormal glucose homoeostasis as defined by the following criteria: 1. Abnormal GCT (>140 mg/dl) with normal OGTT; 2. Normal GCT with only Impaired Fasting Glucose(IFG) in OGTT; 3. Normal GCT with Gestational Glucose Intolerance(GGI); 4. Patients diagnosed as GDM: a. If fasting is >126mg/dl; b. If 2hr OGTT ≥ 140mg/dl & ≤ 199 mg/dl; c. If value of either GCT or OGTT >200 mg/dl. The control group comprised of women with normal GCT and normal OGTT. In all the above groups, adverse prenatal outcome and maternal outcomes were evaluated by the primary and secondary outcome measures. Results: There were 10 cases (15.3%) of hypertensive disorder of pregnancy in the study group (3 cases of gestational hypertension in abnormal GCT, 3 cases of pre eclampsia in each GGI and GDM and 1 antepartum eclampsia in GGI category) and 2 cases in control group (3%) (p=0.03). There were 2 cases of Fetal Growth Reduction (FGR) and 5 cases of Premature Rupture Of Membranes(PROM) in both study and control group. There was 1 case of cholestasis of pregnancy in study group. Term inductions were 11 and 13 in the study and control group respectively.Within the study group number of cases induced were more in GGI(n=7) and GDM(n=4) category. There were 14 caesarean sections (21.5%) and 2 (3%) instrumental deliveries among the study group. However there were 6 caesarean sections (9.2%) and no instrumental deliveries among control groups. The rate of elective LSCS is more in GDM (n=5) vs other 3 categories and the difference is significant (p=0.04) The overall number of LSCS (14 cases) was significantly higher in GDM. Conclusion: Cases with abnormal glucose homeostasis of lesser degree than GDM, like only abnormal GCT, IFG and GGI also were observed to have adverse maternal outcomes than controls, in form of hypertensive disorders of pregnancy, significantly higher LSCS rates, and increased risk of macrosomia. Instead of 2 step procedure, single step screening cum diagnostic test with 75 gm OGTT for diagnosing GDM could be an option to be universally practiced.

The article shows the results of the study using drug Ropren in the patients with acute coronary syndrome. Ropren is  a plant drug containing polyprenols — dolichol precursors which take part in dolichol phosphate pathway. The pathology in this pathway leads to disbalance and glycoprotein deficiency. This is the reason of large group of diseases. This study is randomized double blind placebo controlled (No. NCT03122340 at ClinicalTrials.gov). Patients (n=68) with ACS taking standard therapy including atorvastatin 40 mg/day were randomized into to 2 groups: group 1 (n=34) took Ropren  8 drops 3 times per day for 3 week, then 5 drops 3 times per day for 5 weeks; group 2 (n=34) took placebo in the same dose regimen. After two — month therapy there was a positive dynamic (decreasing) in the level of interleukin-6 in the study group whereas in the control group there was no statistically significant change: 4.36 (2.61, 8.95) and 5.5 (3.3; 8.4) pg/ml, respectively (p<0.05). In the group of patients taking Ropren the reduction or cessation of statin was required significantly less than in the placebo group: 3 (8.8%) vs 9 (26.5%), respectively. One patient from the first group had a side effect in the form of gravity in the right hypochondrium. That is why the administration of Ropren in addition to standard therapy is reasonable in patients with ACS.
