Objectives Widespread implementation of electronic databases has improved the accessibility of plaintext clinical information for supplementary use. Numerous machine learning techniques, such as supervised machine learning approaches or ontology-based approaches, have been employed to obtain useful information from plaintext clinical data. This study proposes an automatic multi-class classification system to predict accident-related causes of death from plaintext autopsy reports through expert-driven feature selection with supervised automatic text classification decision models. Methods Accident-related autopsy reports were obtained from one of the largest hospital in Kuala Lumpur. These reports belong to nine different accident-related causes of death. Master feature vector was prepared by extracting features from the collected autopsy reports by using unigram with lexical categorization. This master feature vector was used to detect cause of death [according to internal classification of disease version 10 (ICD-10) classification system] through five automated feature selection schemes, proposed expert-driven approach, five subset sizes of features, and five machine learning classifiers. Model performance was evaluated using precisionM, recallM, F-measureM, accuracy, and area under ROC curve. Four baselines were used to compare the results with the proposed system. Results Random forest and J48 decision models parameterized using expert-driven feature selection yielded the highest evaluation measure approaching (85% to 90%) for most metrics by using a feature subset size of 30. The proposed system also showed approximately 14% to 16% improvement in the overall accuracy compared with the existing techniques and four baselines. Conclusion The proposed system is feasible and practical to use for automatic classification of ICD-10-related cause of death from autopsy reports. The proposed system assists pathologists to accurately and rapidly determine underlying cause of death based on autopsy findings. Furthermore, the proposed expert-driven feature selection approach and the findings are generally applicable to other kinds of plaintext clinical reports. © 2017 Mujtaba et al.

Objective: To determine the efficacy of transdermal Nitroglycerine patch in idiopathic pre-term labour and foeto-maternal outcome. Methods: This quasi-experimental study was conducted at the Obstetrics Unit-II of Shaikh Zayed Hospital for Women, Chandka Medical College, Shaheed Mohtarma Benazir Bhutto Medical University, Larkana, from Jan 1 to June 30, 2010. Sixtyfive pregnant women at 28-34 weeks of gestation were recruited after they met the selection criteria based on non-probability consecutive sampling. Initially, 73 patients were selected, but 65 of them completed the treatment, while 8 patients refused to continue. Patients diagnosed with pre-term labour were given glyceryl trinitrate (GTN) 5 mg/12 hours transdermal patch which was applied on the anterior abdominal wall. The second patch of same dose was given after 12 hours. Arrest of labour, prolongation of pregnancy in days or weeks along with side effects of the agent were monitored. Patients were followed till delivery to know the foeto- maternal outcome. Results: Dramatic effects were seen in around 60 (92.3%), of the total patients who had felt relief from premature labour pains within the first hour and only 5 (7.6%) patients could not go beyond 24 hours, as among them 3 (4.61%) had previous uterine scar and 2 (3.07%) developed ruptured membranes after 12 hours of admission and their babies also could not survive. Mean pregnancy prolongation was 15.35±9.45 days (min: 4 max: 35), so delivery was deferred up to 48 hours, 3 to 7 days and more than 7 days in 4 (6.15%), 6 (9.23%) and 50 (76.92%) respectively. Conclusion: Glyceryl trinitrate, trans dermal patch is effective and safe tocolytic in idiopathic preterm labour. By prolonging pregnancy it improves neonatal outcome.

Spontaneous bacterial peritonitis (SBP) is defined as an ascitic fluid infection without an evident intra-abdominal surgically treatable source. Spontaneous bacterial peritonitis (SBP) is one of the severe complications in patients with cirrhosis and ascites. Without early antibiotic treatment, this complication is associated with high mortality rate, so early diagnosis and treatment of SBP is therefore necessary for survival. Leukocyte esterase dipstick test can rapidly diagnose the SBP. Objectives were to find out the diagnostic accuracy of leukocyte esterase dipstick test for the diagnosis of spontaneous bacterial peritonitis. This cross-sectional, validation study was conducted from January 2009 to June 2009 at Medical Unit-II, Chandka Medical College Hospital Larkana. All the Patients with cirrhosis and ascites of either gender were included in this study. Paracentesis were performed on admission. The ascitic fluid obtained at bedside was immediately tested with reagent strip Multistix 10 SG. Ascitic fluid was then analysed for PMN cell count. The result of reagent strip was compared with ascitic fluid PMN cell count for determination of sensitivity, specificity, PPV and NPV of the test, while taking ascitic fluid PMN count > or = 250/mm3 as standard for diagnosis of SBP. Leukocyte esterase dipstick read positive from +1 to +3 reaction while negative and trace reaction regarded as negative test result. Total ninety four patients were enrolled in this study. Ninety-four Ascitic fluid samples were obtained. SBP was diagnosed in 52 (55.3%) patients, 42 (44.7%) patients were negative for SBP by manual cell count. The sensitivity, specificity, PPV, NPV of leukocyte esterase dipstick test to diagnose SBP were 92%, 95%, 96%, 90% respectively. The leukocyte esterase dipstick test can be used as rapid test for diagnosis of SBP due to its high diagnostic validity.

In this study, a novel approach has been developed using differential pulse anodic stripping voltammetry (DPASV) for the simultaneous determination of Zn(II), Cd(II), Pb(II) and Cu(II) in edible oils at hanging mercury drop electrode. The microwave digestion of oil samples was carried out with concentrated HNO3 and H2O2. KNO3 was used as a supporting electrolyte. The experimental conditions optimized such as deposition time, stirring rate and size of mercury drop were 300 s, 600 rpm and 10 mm2, respectively. The method was applied to quantify Zn(II), Cd(II), Pb(II) and Cu(II) in crude and refined hazelnut, corn, sunflower and olive oils. During refining of different vegetable oils, the removal efficiencies of Zn(II), Cd(II), Pb(II) and Cu(II) were calculated as 98.20-99.91, 98.50-99.90, 95.26-99.76 and 95.93-99.92 %, respectively. The limits of detection for Zn(II), Cd(II), Pb(II) and Cu(II) were 2.1 × 10-8, 8.7 × 10-10, 7.1 × 10-9 and 3.4 × 10-9 and the limits of quantification were 6.8 × 10-8, 2.9 × 10-9, 2.3 × 10-8 and 1.1 × 10-8 M with linear regression coefficients (R 2) of 0.9930, 0.9928, 0.9893 and 0.9931, respectively. It was observed that the above metals in crude and refined vegetable oils could be determined simultaneously by the DPASV method. © 2013 Springer Science+Business Media New York.

Administration of quinolone therapy is controversial during growing age as stated by earlier authors. The flouroquinolones are currently not indicated for young children because of arthropathy and adverse effect as new born shown by studies. However the effects of ciprofloxacin and ZnCl2 on prenatal conceptus have remained undocumented. The present study was designed to compare the effects on conceptus after maternal ingestion of ciprofloxacin and ZnCl2 using Wastar albino rats. Ciprofloxacin and ZnCl2 was administrated to pregnant female albino rats. Ciprofloxacin with a dose of 20 mg/Kg bodyweight and ZnCl2 120 microg/100 gm bodyweight two times therapeutic dose for 10 days (from day 8-18 of pregnancy). Each animal was weighted on day 1, day 8 and day 18 of pregnancy. Abortion resulted on day 18th of pregnancy. Each group of pregnant animals were sacrificed on day 18 of gestation by over dose of either anaesthesia, abdomen opened, uterus and both cornua containing conceptus identified, removed, there weight recorded, crown rump length was measured and was compared with similar value of control animals. The results were statistically analysed to find out the significance. The ciprofloxacin induces a mordanting effect as obviated by increased basophilia. Our study reveals that ciprofloxacin administered in maternal, decreased maternal body weight to 38.4 +/- 0.9 gm. However simultaneous ZnCl2 maintained the body weight to 41.4 +/- 0.7 gm, while ZnCl2 increased the body weight to 46.5 +/- 2.25 gm. The body weight and Crown Rump length (CR Length) in conceptus decreased by 4.52 +/- 0.10 gm and 3.06 +/- 0.09 Cm respectively. That ciprofloxacin and ZnCl2 administration maintained the body weight and CR length by 5.46 +/- 0.09 gm and 3.79 +/- 0.13 Cm respectively. That ZnCl2 administration increased the body weight and CR length by 6.71 +/- 0.05 gm and 4.15 +/- 0.08 Cm respectively. Prenatal administration of Ciprofloxacin caused reduction in growth rate and CR length, and ZnCl2 maintained body weight and CR length and growth of the rat conceptus.

Waardenburg anophthalmia syndrome (WAS), also known as ophthalmo-acromelic syndrome or anophthalmia-syndactyly, is a rare congenital disorder that segregates in an autosomal recessive pattern. Clinical features of the syndrome include malformation of the eyes and the skeleton. Mostly, WAS is caused by mutations in the SMOC-1 gene.The present report describes a large consanguineous family of Pakistani origin segregating Waardenburg anophthalmia syndrome in an autosomal recessive pattern. Genotyping followed by Sanger sequencing was performed to search for a candidate gene.SNP genotyping using AffymetrixGeneChip Human Mapping 250K Nsp array established a single homozygous region among affected members on chromosome 14q23.1-q24.3 harboring the SMOC1 gene. Sequencing of the gene revealed a novel homozygous missense mutation (c.812G>A; p.Cys271Tyr) in the family.This is the first report of Waardenburg anophthalmia syndrome caused by a SMOC1 variant in a Pakistani population. The mutation identified in the present investigation extends the body of evidence implicating the gene SMOC-1 in causing WAS.
