Objective: To compare accuracy of manual muscle testing in detection of strength differences across grade 4 and 5 at different percentage deficits of dynamometric mean in shoulder flexors of young females.  Methods: Cross sectional research design, conducting primary analysis of strength of shoulder flexors measured through manual muscle testing and hand-held dynamometer. Three hundred young healthy females without any ailment of upper extremity or generalized health problem were selected from University of South Asia and Association of Fatima Jinnah Old Graduates, Lahore. Non-probability convenient sampling technique was used. The age group selected was 18-39 years. The strength of shoulder flexors measured through manual muscle testing and hand-held dynamometer was main outcome measure. Results: The overall diagnostic accuracy of manual muscle testing showed better results at 10% dynamometric measures. It was 63.33%(95% CI: 57.74%, 68.59%) in non-dominant shoulder flexors and 61.67% (95% CI: 56.05%, 66.99%) in dominant shoulder flexors. The positive predictive value (PPV) and specificity of manual muscle testing was better at 10% strength deficit in comparison with dynamometric measures, whereas negative predictive value (NPV) and sensitivity was better at 20% strength deficit. Contrasting association was found between positive predictive value (PPV) and sensitivity, negative predictive value and specificity.  Conclusion: The subjective area of grade 4 and 5 showed better, although not ideal, diagnostic worth at 10% deficit of dynamometric measures in shoulder flexors. Further exploration through study of contrasting trends between PPV and sensitivity by subgroup analysis is required. Continuous...

Background: Specific learning disorder (SLD) is a neurodevelopmental disorder characterized by impairment in reading, written expression, and arithmetic. It can be identified during early school days itself. There is a lack of a screening tool for SLD that is properly validated and easy to administer. This study is an attempt to validate an ultrashort tool for screening SLD. Methods: This cross-sectional study was done at Government Medical College Ernakulam, South India. Children aged 6–16 years attending Psychiatry Outpatient Department were recruited by consecutive sampling. The self-administered screening tool, known as Ernakulam Learning Disorder (ELD) tool, was given twice within a gap of 2 months, and the results were compared with the clinical diagnosis, which was taken as the gold standard. The sensitivity, specificity, positive predictive value, negative predictive value, and kappa of the screening tool were calculated. Results: The sample consisted of children aged 8–16 years. The sensitivity and specificity of the tool were found to be 98.2 (95% confidence interval [CI] = 90.4–100) and 87.5 (CI = 76.8–94.4), respectively. The positive predictive value was 87.3 (CI = 76.5–94.4) and the negative predictive value was 98.2 (CI = 90.6–100). The kappa value was 0.96 (CI = 0.92–1.01). Conclusions: ELD tool seems highly useful as a screening instrument for detecting SLD; it is simple, easy to remember, and easy to administer.

ABSTRACT Background Pap smear is the most commonly used screening test for cervical cancer, however it has disadvantage of having low sensitivity. Colposcopy has higher sensitivity as compared to Pap smear but low specificity. Sequential screening with both Pap smear and colposcopy can overcome these problems. Aim The study was aimed to find out the diagnostic efficacy of both Pap smear and colposcopy. It was also intended to find out the advantages of sequential use of Pap smear and colposcopy in screening for cervical cancer. Design It was a cross-sectional study conducted in colposcopy clinic of KLE's Dr. Prabhakar Kore Hospital and MRC, Belgaum from November 2006 to September 2008. Material and methods A total of 190 patients with complaints of postcoital bleeding, intermenstrual bleeding, postmenopausal bleeding, persistent vaginal discharge or those found to have an unhealthy cervix on per speculum examination were included in the study. In all the 190 cases Pap smear, colposcopic evaluation and colposcopic directed biopsy were performed. Statistical analysis Sensitivity, specificity, positive predictive value, negative predictive value of both Pap smear and colposcopy were calculated with histopathology as a gold standard, keeping LSIL as a disease threshold for test positivity. Results Pap smear was positive in 14.21% (27/190) cases, colposcopy was positive in 37.89% (72/190) cases. Biopsy confirmed LSIL and higher lesions in 31.57% cases. The sensitivity, specificity, positive predictive value and negative predictive value of Pap smear were 41.66%, 96.92%, 86.21% and 78.26% respectively and 80%, 81.54%, 66.66% and 89.83% respectively for colposcopy. Combined colposcopy and Pap smear could accurately diagnose 53/60 biopsy confirmed cases of LSIL and higher lesions with an accuracy of 88.33%. Conclusion Sequential use of Pap smear and colposcopy in screening for cervical cancer increases the accuracy of the test.

Tubal Patency

Background: Laparoscopy is considered as the gold standard for assessment of tubal factors of infertility, although because of its invasive nature, cost and the need for anaesthesia and hospitalization, HSG seems to be a basic routine procedure for tubal factors. Currently with the availability of the ultrasonography machines with very good resolution, SSG can be simultaneously practiced with ultrasonography during day 7-9 of the menstrual cycle to assess tubal patency. Hence, the present study was designed to compare the accuracy of HSG with SSG for evaluation of tubal factor infertility.Methods: This was a prospective cross-sectional study of 100 consecutive women with primary or secondary infertility without active pelvic infection, selected from OPD of Department of Obstetrics and Gynaecology, Acharya Vinoba Bhave Rural Hospital associated with Datta Meghe Institute of Medical Sciences University, Sawangi (Meghe), Wardha over a period of two years from September 2014 to August 2016.Results: In the present study for diagnosing tubal patency SSG had sensitivity of 88.64%, specificity of 75%, positive predictive value of 96.29% and negative predictive value of 47.36% and diagnostic accuracy of 87%, while HSG had sensitivity of 94.32%, specificity of 83.33%, positive predictive value of 97.64% and negative predictive value of 66.66% and diagnostic accuracy of 93%.Conclusions: Initial assessment of tubal patency by HSG is better than SSG as an indirect, outdoor, non-invasive procedure although with minimal radiation hazards. It allows documentation of tubal patency enables detection of several tubal lesions and permits assessments of the fine intratubal architectural details as well as little uterine pathology. It will help in reducing the number of laparoscopic procedures and their related complications and health care costs for confirmation of tubal patency.

Abstract Background Most studies of chronic kidney disease (CKD) in Sub-Saharan Africa (SSA) have been conducted in urban settings. They relied on GFR estimated from serum creatinine alone and on the inexpensive, convenient urinary dipstick to assess proteinuria. The dipstick for proteinuria has not been directly compared with the gold standard albumin-to-creatinine ratio (ACR) in a large-sized study in SSA. We hereby assessed the influence of rural versus urban location on the level, interpretation, and diagnostic performance of proteinuria dipstick versus ACR. Methods In a cross-sectional population-based study of CKD in both urban (n = 587) and rural (n = 730) settings in South-Kivu, Democratic Republic of Congo (DRC), we assessed the prevalence, performance (sensitivity, specificity, positive predictive value and negative predictive value) and determinants of a positive dipstick proteinuria as compared with albuminuria (ACR). Albuminuria was subdivided into: A1 (< 30 mg/g creatinine), A2 (30 to 299 mg/g creatinine) and A3 (≥ 300 mg/g creatinine). Results The overall prevalence of positive dipstick proteinuria (≥ 1+) was 9.6 % (95 % CI, 7.9–11.3) and was higher in rural than in urban residents (13.1 % vs. 4.8 %, p < 0.001), whereas the prevalence of albuminuria (A2 or A3) was similar in both sites (6 % rural vs. 7.6 % urban, p = 0.31). In both sites, dipstick proteinuria ≥ 1 + had a poor sensitivity (< 50 %) and positive predictive value (< 11 %) for the detection of A2 or A3. The negative predictive value was 95 %. Diabetes [aOR 6.12 (1.52–24.53)] was a significant predictor of A3 whereas alkaline [aOR 7.45 (3.28–16.93)] and diluted urine [aOR 2.19 (1.35–3.57)] were the main predictors of positive dipstick proteinuria. Conclusions ACR and dipstick proteinuria have similar positivity rates in the urban site whereas, in the rural site, dipstick was 2-fold more often positive than ACR. The poor sensitivity and positive predictive value of the dipstick as compared with ACR makes it unattractive as a screening tool in community studies of CKD in SSA.

Objective: To compare the accuracy of Upper lip bite test with modified Mallampati classification for predicting the difficultlaryngoscopic intubation. Study Design: Cross sectional Study. Place and duration of study: The study was carried out at Department ofAnaesthesiology, Intensive Care and Pain management, Combined Military hospital, Rawalpindi from September 2008 to August 2009.Patients and Methods: Four hundred patients undergoing elective surgery meeting the inclusion/exclusion criteria were enrolled afterwritten informed consent. The airways of the patients were evaluated by using the modified Mallampati classification (MMP) and theUpper lip bite test (ULBT). MMP class 3 or 4 and ULBT class 3 were considered as indicators of difficult intubation. The laryngeal view wasgraded by Cormack and Lehane classification (Gold standard). Grade 1 or 2 was considered to represent easy intubation and grade 3 or 4to represent difficult intubation. Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy werecalculated for both the tests separately by using the 2×2 table. Results: ULBT had a higher accuracy of 94%, specificity of 99.2% andpositive predictive value 70% compared to MMP accuracy of 82.7%, specificity of 84.4% and positive predictive value of 22.7%.Conclusions: The diagnostic accuracy of the Upper lip bite test was more than the modified Mallampati classification. We suggest that itbe compared with the other prevailing tests as well which are often used to assess difficult intubations.

Background and Aim: Ovarian cancer is among the most common cancers in women worldwide. CA125 is the most frequent biomarker used in the screening for ovarian cancer. CA125 has no high sensitivity and specificity as a screening test in the medical community; however, because of being simple and noninvasive, it is almost always requested for evaluation and ruling out cancer. It plays an important role in the treatment and post-treatment process, the prediction of prognosis, and the relapse of the disease. The present study aimed to determine the relationship between a high level of CA125 tumor marker and ovarian cancer by detecting spesivity, sensivity, positive and negative predictive values. Methods & Materials: In this cross-sectional study, all cases undergoing CA125 test in Velayat Hospital in 2017-1028 were evaluated for having ovarian cancer. In addition, the CA125 level was compared between healthy individuals and patients with ovarian cancer. Finally, the obtained data were analyzed using SPSS. Ethical Considerations: The present study was approved by the Qazvin University of Medical Sciences (Ethics Code: IR.QUMS.REC.1396.316). Results: In this study, 35.3% of the study participants received a definite diagnosis of ovarian cancer. Generally, CA125 values were negative in 41.8% and positive in.58.2% of the study subjects. The sensitivity of the test was measured as 80.1%, the specivity as 53.6%, the positive predictive value equaled 48.4%, and the negative predictive value was measured as 83%. There was a significant relationship between age and the presence of ovarian cancer, and serum CA125 levels. Conclusion: The present study suggested that age and the serum level of CA125 were statistically significant. Finally, CA125 levels were significantly related to ovarian cancer. It provided moderate specivity and specivity as well as low positive predictive value and high negative predictive value as a tumor marker; it is valuable for ruling out of tumor but not appropriate as a screening test.

Background: Dysarthria is manifested as a disorder of movement, it is important to recognize that sensori-motor integration (with tactile, proprioceptive, and auditory feed-back representing the crucial sensory components) is essential to speech motor control, from this standpoint, most or all dysarthria localized to the central nervous system should be thought of as sensori-motor rather than simply motor disturbances.Methods: This non-interventional, cross-sectional comparative, observational study, conducted in 100 study subjects (50 cases and 50 controls) from March 2016 to February 2017 at MGM medical college and MY hospital Indore, MP, India.Results: The mean age of normal population was 53 years and that of dysarthric population was 55 years. Among the dysarthric group, there were 10 cases of ataxic dysarthria, 23 cases of spastic dysarthria, and 9 cases of hypo kinetic dysarthria. There were 20 cases of mild dysarthria 19 cases of moderate dysarthria and 10 cases of severe dysarthria. In ataxic dysarthria, pitch break was found in 6 out of 10 subjects. It was found that there is negative predictive value 93.33%, and positive predictive value, 77.14% in spastic dysarthria and negative predictive value, 83.33% and positive predictive value, 90.90% in ataxic, whereas negative predictive value, 85.71% and positive predictive value, 95.34% in hypo kinetic dysarthria.  Conclusions: Different types of dysarthria when analyzed with software tool after extracting pitch and formants showed specific patterns. These patterns correlated with the clinical diagnosis. And Pattern recognition of different dysarthria will help to identify the types of dysarthria in scientific way and prevent inter-subject variability.
