Objectives: To determine the diagnostic accuracy of ratio of neck circumferenceto thyromental distance to predict the difficult intubation in obese patients by using Intubationdifficulty scale as gold standard. Study Design: Cross-sectional study. Place and Durationof Study: Jinnah Hospital, Department of Anesthesia, Lahore from August 2013 to July 2014.Methodology: 250 patients were included. Ratio of neck circumference to thyromental distancewas measured during preoperative assessment in all patients. Results: There were 59.2% malesand 40.8% females with mean age of patients was 37.13+11.64 years. 19.2% patients showeddifficult intubation and 80.8% easy. Sensitivity of NC/TM was 89.58% and Specificity 72.77% withpositive predictive value of 43.88% and Negative predictive value of 96.71%. Conclusion: Neckcircumference to thyromental distance ratio is sensitive method for determining the difficultintubation among obese patients.

Introduction: In perimenopausal age group particularly, 70% of all gynaecological consultations are for Abnormal Uterine Bleeding (AUB). About 30% of women seek medical assistance for AUB during their reproductive age group and about one third of hysterectomies are carried out for AUB alone. Aim: To determine the sensitivity, specificity, positive predictive value and negative predictive value of Transvaginal Ultrasonography (TVS) versus hysteroscopy in detecting uterine abnormalities Materials and Methods: A cross-sectional study in patients with AUB, admitted to the Department of Obstetrics and Gynaecology at RGGWCH, Puducherry between February 2016 and February 2017 who met the inclusion criteria were included. Sample size was 85 cases. After taking detailed history and physical examination the patient was investigated to rule out organic causes of AUB and then TVS and hysteroscopy were done. Any intrauterine pathology was looked for and endometrial sampling was taken from the abnormal sites for Histopathological Examination (HPE). Both TVS and hysteroscopy results were compared with histopathology which is the gold standard. Results: The sensitivity of TVS in diagnosis of uterine fibroid in comparison to hysteroscopy was 94.74% and the specificity was 71.21%. The sensitivity of hysteroscopy in diagnosis of endometrial hyperplasia in comparison to HPE was 75% and the specificity was 87.01%. The sensitivity of TVS in diagnosis of endometrial hyperplasia in comparison to HPE was 37.5% and the specificity was 90.91%. The sensitivity of hysteroscopy in diagnosis of polyp in comparison to HPE was 100% and the specificity was 97.3%. The sensitivity and specificity of TVS in diagnosis of polyp in comparison to HPE were 9.09% and 93.24%, respectively. Conclusion: TVS had a high sensitivity to detect fibroids but its value in detecting hyperplasia and polyps was in question in this study. But hysteroscopy had a maximum sensitivity to detect polyps and high sensitivity to detect endometrial hyperplasia compared to histopathology which is a gold standard investigation.

Objective: To determine the diagnostic accuracy of High-resolution computed tomography (HRCT) chest in detection of covid-19 infection taking PCR as gold standard. Study Design: Cross-sectional study Setting: Radiology department of Tabba Hospital, Karachi. Duration: From March 2019 to September 2020 Material and Methods: All the clinically suspected patients of covid-19, of any age, both genders and those referred to radiology for High-resolution computed tomography (HRCT) chest to detect the covid-19 infection were included. After two days, patients’ PCR reports were collected from the ward, after taking informed consent and permission from head of department. The diagnostic accuracy of HRCT was established with respect to sensitivity, PPV, NPV, and specificity by taking PCR as gold standard. All the information was collected via study proforma. Results: Total 70 patients suspected for COVID-19 were studied, and the patients’ mean age was 58.23±9.52 years. Males were in majority 54(77.1%). As per HRCT findings, COVID-19 infection was positive in 46 patients, however, 48 patients were detected positive for COVID-19 infection as per PCR findings. In the detection of COVID-19 infection, HRCT chest showed sensitivity of 91%, specificity of 90%, PPV of 83%, NPV of 84% and diagnostic accuracy of 94%; by taking PCR as gold standard. Conclusion: High-resolution computed tomography (HRCT) is a reliable diagnostic approach in promptly detecting the COVID-19; with 91% sensitivity, 90% specificity, 83% positive predictive value, 84% negative predictive value and 94% diagnostic accuracy.

Capillary Sampling

Gestational diabetes mellitus (GDM) is a common complication with negative impacts on mother and child. The primary aim of this study was to examine whether plasma glucose cutoffs for GDM diagnosis based on venous sampling can be replaced by cutoffs based on capillary sampling. A prospective cross-sectional study was performed at an antenatal care clinic including 175 pregnant women undergoing an oral glucose tolerance test (OGTT). Duplicate samples were collected by capillary and venous puncture while fasting and 1 h and 2 h after an OGTT. Both samples were analyzed on Accu-Chek Inform II. The cutoffs for a GDM diagnosis using capillary samples were corrected from 5.1 to 5.3 mmol/L for the fasting sample, from 10.0 to 11.1 mmol/L for the 1 h sample, and from 8.5 to 9.4 mmol/L for the 2-h sample using half of the dataset. Applying these cutoffs to the remaining dataset resulted in a sensitivity, specificity, and accuracy of 85.0%, 95.0%, and 90.3%, respectively, with a positive predictive value (PPV) of 83%, an negative predictive value (NPV) of 96%, and a positive negative likelihood ratio (LHR) of 16.4 using capillary sampling for the GDM diagnosis at fasting and 2-h after. Corrected cutoffs and capillary samples can be used for the diagnosis of GDM with maintained diagnostic accuracy using Accu-Chek Inform II.

Baermann Technique

Strongyloidiasis is a soil-transmitted helminthiasis with a high global prevalence. Objectives: We aimed to evaluate the prevalence of Strongyloides stercoralis infection and assess strongyloidiasis serology as a screening technique in the Peruvian Amazon. Material and Methods: We performed a cross-sectional study of strongyloidiasis in 300 pregnant women in Iquitos (Peru) from 1 May 2019 to 15 June 2019. Women were tested using serology (Strongyloides IgG IVD-ELISA kit) as an index test and the modified Baermann technique and/or charcoal fecal culture as the parasitological reference standard. Results: The reference tests showed S. stercoralis in the stool of 30 women (prevalence: 10%; 95% confidence interval [CI] 7.1% to 13.9%), while 101 women tested positive on the blood test (prevalence: 33.7%; 95% CI 28.6% to 39.4%). Fourteen of the 15 women (93.3%) with positive results according to the modified Baermann technique, and 14 of the 23 women (56.5%) with positive charcoal cultures also had positive serological results. Serology showed a sensitivity of 63.3% and a negative predictive value of 94.4%. Conclusion: In Iquitos, pregnant women have a high prevalence of S stercoralis. S. stercoralis ELISA could be an excellent tool for population-based screening, as it has a high negative predictive value that can help to rule out the presence of active infection.
