Diagnostic utility of anti-citrullinated protein antibody and its comparison with rheumatoid factor in rheumatoid arthritis

Objective: To assess the diagnostic utility of anti-citrullinated protein antibody (anti-CCP) in rheumatoid arthritis (RA) and compare it with rheumatoid factor (RF). Study Design: Analytical study. Place and Duration of Study: Section of Chemical Pathology, Department of Pathology and Microbiology and Medicine, the Aga Khan University, Karachi, from January to May 2010. Methodology: A review of medical records of patients presenting to the clinics with complaints of muscular or joint pains and who were tested for their serum anti-CCP was done. Inclusion criteria were presence of clinical synovitis in at least one joint and an absence of alternative diagnosis. Patients with arthralgia alone or with missing acute phase reactants information were excluded. Scoring and classification of RA was done using the 2010 RA Classification Criteria by the American College of Rheumatology (ACR). Results: Out of the 98 charts reviewed, ACR criteria showed 54 cases with RA. The mean age of the group was 46 ± 15 years, 82.7% being females. High titers of anti-CCP corresponded with the ACR scores. The sensitivity and specificity of anti-CCP and RF reactivity for the diagnosis of RA were 54.7% and 95.5% versus 59.3% and 88.4% respectively. Conclusion: Anti-CCP is useful for the diagnosis of RA due to its higher specificity as compared to RF and can predict disease severity

Mortality-related resource utilization in the inpatient care of hypoplastic left heart syndrome.

BACKGROUND: Quantifying resource utilization in the inpatient care of congenital heart diease is clinically relevant. Our purpose is to measure the investment of inpatient care resources to achieve survival in hypoplastic left heart syndrome (HLHS), and to determine how much of that investment occurs in hospitalizations that have a fatal outcome, the mortality-related resource utilization fraction (MRRUF). METHODS: A collaborative administrative database, the Pediatric Health Information System (PHIS) containing data for 43 children\u27s hospitals, was queried by primary diagnosis for HLHS admissions of patients ≤21 years old during 2004-2013. Institution, patient age, inpatient deaths, billed charges (BC) and length of stay (LOS) were recorded. RESULTS: In all, 11,122 HLHS admissions were identified which account for total LOS of 277,027 inpatient-days and $3,928,794,660 in BC. There were 1145 inpatient deaths (10.3%). LOS was greater among inpatient deaths than among patients discharged alive (median 17 vs. 12, p \u3c 0.0001). BC were greater among inpatient deaths than among patients discharged alive (median 4.09 × 10(5) vs. 1.63 × 10(5), p \u3c 0.0001). 16% of all LOS and 21% of all BC were accrued by patients who did not survive their hospitalization. These proportions showed no significant change year-by-year. The highest volume institutions had lower mortality rates, but there was no relation between institutional volume and the MRRUF. CONCLUSIONS: These data should alert providers and consumers that current practices often result in major resource expenditure for inpatient care of HLHS that does not result in survival to hospital dismissal. They highlight the need for data-driven critical review of standard practices to identify patterns of care associated with success, and to modify approaches objectively

Newborn screening for congenital hypothyroidism: Improvement in short-term follow-up by audit and monitoring

Objective: Newborn screening for congenital hypothyroidism (CH) at our hospital during this study was by measurement of thyroid stimulating hormone (TSH) in serum samples. This audit was conducted over a 2 year period, to determine the compliance of reporting of results greater than the screening cutoffs for serum TSH. Gaps of non-compliance were identified, and re-audit was undertaken after the corrective actions were taken.Results: The critical limit was defined as serum TSH (≥ 20 µIU/ml) following consultation with a pediatric endocrinologist. All results above this limit were reported urgently to physicians. During the audit period, 27,407 tests were performed, 0.7% had a value of ≥ 20 µIU/ml, of those only 62% were reported to the general paediatrician or neonatologist. Reasons for not reporting results included non-availability of contact information, lack of policy awareness by technologists, critical results not highlighted on the computer display, and absence of regular monitoring. Corrective measures were taken, and re-audit was done. During the re-audit period, a total of 22,985 tests was performed, 0.6% had a value of ≥ 20 µIU/ml. Of these, 77% were reported to the general paediatrician or neonatologist. Critical result reporting was improved after the audit, and further enhanced the laboratory service of CH screening

Association between environmental tobacco smoke and dental caries amongst 5-14 years old children in Karachi, Pakistan.

Objective:To determine the association between environmental tobacco smoke and dental caries.Methods:This cross-sectional study was conducted in peri-urban and urban areas of Karachi, from February to August 2014, and comprised children aged 5-14 years. A pre-coded questionnaire for environmental tobacco smoke and food frequency questionnaire for dietary habits were used. Dental examination of children was done to detect caries. Cox-proportional hazard algorithm was used to measure the association of environmental tobacco smoke with dental caries at multivariable level. STATA version 12.0 was used for statistical analysis.Result:Of the 500 children, 250(50%) each were from peri-urban and urban localities. The prevalence of dental caries was 336(67.2%).Family members of 154(30.8%) participants reported smoking. After adjusting for junk food intake, in-between meals, age, plaque index, dental visits and socio-economic status, the association between environmental tobacco smoke and dental caries remained statistically significant (p30 minutes of environmental tobacco smoke exposure, respectively.Conclusions:Environmental tobacco smoke was found to be associated with dental caries

Omental Patching and Purse-String Endosuture Closure after Endoscopic Full-Thickness Resection in Patients with Gastric Gastrointestinal Stromal Tumors

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, primarily arising from the stomach. With the widespread utilization of and technical advancements in endoscopy, gastric GISTs are being increasingly detected at an early stage, enabling complete endoscopic resection. Endoscopic full-thickness resection (EFTR) is an advanced technique that has been recognized as a treatment tool for neoplasms in the digestive tract in selected patients. Although a number of methods are available, closing large iatrogenic defects after EFTR can be a concern in clinical practice. If this potential problem is appropriately solved, patients with gastric GISTs would be suitable candidates for resection utilizing this technique. To our knowledge, this is the first study to propose omental patching and purse-string endosuture closure following EFTR as a feasible endoscopic option in patients with gastric GISTs

Assisting and Opposing Stagnation Point Pseudoplastic Nano Liquid Flow towards a Flexible Riga Sheet: A Computational Approach

Nanofluids are used as coolants in heat transport devices like heat exchangers, radiators, and electronic cooling systems (like a flat plate) because of their improved thermal properties. The preeminent perspective of this study is to highlight the influence of combined convection on heat transfer and pseudoplastic non-Newtonian nanofluid flow towards an extendable Riga surface. Buongiorno model is incorporated in the present study to tackle a diverse range of Reynolds numbers and to analyze the behavior of the pseudoplastic nanofluid flow. Nanofluid features are scrutinized through Brownian motion and thermophoresis diffusion. By the use of the boundary layer principle, the compact form of flow equations is transformed into component forms. The modeled system is numerically simulated. The effects of various physical parameters on skin friction, mass transfer, and thermal energy are numerically computed. Fluctuations of velocity increased when modified Hartmann number and mixed convection parameter are boosted, where it collapses for Weissenberg number and width parameter. It can be revealed that the temperature curve gets down if modified Hartmann number, mixed convection, and buoyancy ratio parameters upgrade. Concentration patterns diminish when there is an incline in width parameter and Lewis number; on the other hand, it went upward for Brownian motion parameter, modified Hartmann, and Prandtl number
