Abstract
Smog has become the fifth season of Pakistan especially in Lahore city. Increased level of air pollutants (primary and secondary) are thought to be responsible for the formation of smog in Lahore. Therefore, the current study was carried out for the evaluation of air pollutants (primary and secondary) of smog in Wagah border particularly and other sites (Jail road, Gulburg) Lahore. For this purpose, baseline data on winter smog from March to December on primary and secondary air pollutants and meteorological parameters was collected from Environmental Protection Department and Pakistan Meteorological Department respectively. Devices being used in both departments for analysis of parameters were also studied. Collected data was further statistically analyzed to determine the correlation of parameters with meteorological conditions and was subjected to air quality index. According to results, PM 10 and PM 2.5 were found very high above the NEQS. NOx concentrations were also high above the permissible limits whereas SO2 and O3 were found below the NEQS thus have no roles in smog formation. Air Quality Index (AQI) of pollutants was PM 2.5(86-227), PM 10 (46-332), NOx (26-110), O3 (19-84) and SO2 (10-95). AQI of PM 2.5 remained between moderate to very unhealthy levels. AQI of PM 10 remained between good to hazardous levels. AQI of NOx remained between good to unhealthy for sensitive groups' levels. AQI of O3 and SO2 remained between good to moderate levels. Pearson correlation showed that every pollutant has a different relation with different or same parameters in different areas. It is concluded from the present study that particulate matter was much more responsible for smog formation. Although NOx also played role in smog formation. So there is need to reduce sources of particulate matter and NOx specifically in order to reduce smog formation in Lahore.

Abstract
BACKGROUND AND PURPOSE Minimally invasive parathyroidectomy requires accurate preoperative localization of suspected adenomas, and multiphase CT allows adenoma characterization while providing detailed anatomic information. The purpose of this study was to assess the feasibility of a protocol using only arterial and venous phases to localize pathologic glands in patients with primary hyperparathyroidism. MATERIALS AND METHODS We identified 278 patients with primary hyperparathyroidism who had undergone 2-phase CT with surgical cure. All scans were read prospectively by board-certified neuroradiologists. A neuroradiology fellow retrospectively reviewed images and reports and classified suspected adenomas on the basis of anatomic location. Accuracy was determined by comparing imaging results with surgical findings. The ability of 2-phase CT to localize adenomas to 1 of 4 neck quadrants and lateralize them to the correct side was assessed. Accuracy of identifying multigland disease was also evaluated. RESULTS In patients with single-gland disease, the sensitivity and specificity of 2-phase CT to correctly localize the quadrant were 55.4% and 85.9%, respectively. The sensitivity and specificity of correct lateralization were 78.8% and 67.8%, respectively. The sensitivity and specificity to identify multigland disease were 22.9% and 79.5%, respectively. CONCLUSIONS While the 2-phase CT protocol in this study demonstrates lower accuracy compared with reports of other techniques, its lower radiation compared with 3- and 4-phase techniques may make it a feasible alternative for preoperative parathyroid localization. Further prospective studies are needed to identify patients for whom this technique is most suitable.

Abstract
OBJECTIVE To compare the awareness of provisions of consumer protection act among dental and medical professionals in Udaipur city, Rajasthan, India. MATERIALS AND METHODS In a cross sectional study, a total of 448 professionals (253 males, 195 females) belonging to dental (222) and medical (226) categories were surveyed using a self administered structured questionnaire. The questionnaire comprised of 22 questions about the awareness of consumer protection art (CPA) and whether these professionals were following the recommendations of CPA. The student's t-test, ANOVA test, and Scheffe's test were used as tests of significance. RESULTS The awareness scores were significantly higher for medical professionals compared with those of dental professionals. Similarly, postgraduates showed more awareness in both the professions and it was found that private practitioners significantly have more awareness than the academic sector. CONCLUSION Though medical professionals have more awareness of CPA compared to dental professionals, considering the present scenario, better knowledge of CPA is necessary for both professionals in order to be on the safer side.

Abstract
There has been a rise in the hospital acquired as well as the community acquired Methicillin Resistant Staphylococcus Aures (MRSA) infections in the recent years. We conducted a study to detect colonization rate of staphylococci in the nasopharynx in children and prevalence of MRSA nasopharyngeal carriage in pediatric population. The study included 1300 nasopharyngeal swabs collected from school going children between six to ten years age from Nagpur urban community and inoculated on blood agar for isolation of staphylococci. Isolates were subjected to antimicrobial testing and staphylococcus aureus isolates were also Phage typed at Maulana Azad Medical College, New Delhi. Staphylococci were isolated from nasopharynx of 138 (10.62%) children. Nasopharyngeal carriage of staphylococcus aureus was detected in 7.38% children. Methicillin Resistant Staphylococci constituted 4.16% of the Staphylococcus aureus strains. Colonization rate of MRSA in the pediatric population in the community was detected to be 0.31%. Methicillin Resistant Staphylococcus aureus nasopharyngeal carriage, though not at very high rate, is prevalent in the pediatric population in the community.

Abstract
Avascular necrosis of the femoral head creates considerable morbidity in successful renal transplant recipients who are generally young and expect active lifestyles. Total hip replacement is considered the treatment of choice in these patients, but surgeons may be wary because of a supposed increase in the risk of infection and other complications. A review of the literature reveals that cemented hip arthroplasty provides good to excellent functional outcomes for renal transplant patients. Most authors have found that the risk of infection is not increased despite chronic immunosuppression, but the rates of general complications are and should be anticipated and treated. There is a high rate of early failure in these patients because of their young age and diffuse osteopenia as a result of secondary hyperparathyroidism related to the underlying renal disease and chronic steroid use. Recent studies have found that despite decreased bone stock in these patients, porous-coated prostheses are not contraindicated.

Abstract
PURPOSE The aim of this study was to determine whether fine-needle aspiration cytology (FNAC) of testis alone is sufficient to diagnose testicular function and whether follicle-stimulating hormone (FSH) estimation can be safely eliminated from the evaluation protocol of the azoospermic subject. MATERIALS AND METHODS We studied 46 adult azoospermic males who were infertile for more than 2 years following marriage. Hormonal profile was done in all. Later all 46 patients were subjected to bilateral FNAC of the testes. The cytological findings were correlated with histological findings. RESULTS We found 95.65% agreement between FNAC and testicular biopsy. Though serum FSH estimation was done in all patients in this series, in none of the cases did it affect overall management. CONCLUSION FNAC is a quick, safe and minimally invasive modality. Following a well-performed semen analysis in an azoospermic subject, it appears that FNAC may be the only investigation needed. It provides a reliable diagnosis in patients with either obstructive or non-obstructive azoospermia. Routine estimation of FSH can be omitted from the investigative protocol in these patients.

Abstract
Spontaneous intracerebral haematoma (ICH) is an extremely unusual complication following the evacuation of a chronic subdural haematoma (CSDH). Good outcome is expected after the drainage of the CSDH and neurological deterioration is a cause for serious concern. Authors report three cases of spontaneous ICH away from the site of surgery following evacuation of a CSDH with a review of literature. Changes in cortical blood flow following decompression of a long standing CSDH may be responsible for the ICH.

Abstract
OBJECTIVE To describe modifications to laparoscopic live-donor nephrectomy (LLDN) to make it more cost-effective for developing countries; LLDN was developed as a better alternative to conventional donor nephrectomy, with advantages of an earlier return to normal activities and smaller scars, but is not popular in developing countries because of high cost of disposable items. PATIENTS AND METHODS From January 2000 to January 2002, 148 LLDNs were performed, of which two used a hand-assisted technique, 17 the standard technique, 79 a modified laparoscopically assisted cost-saving approach and 50 by the modified technique. In the latter approach the kidney was delivered through a 6-8 cm anterior subcostal flank incision. In last 50 patients we further modified the technique, clipping the hilum using endoclips and delivering the kidney by holding the lateral pararenal fat through a 5 cm iliac fossa incision. RESULTS The mean age, operative duration, warm ischaemia time, blood loss, analgesic requirements, pain score and hospital stay were comparable among the various techniques used. Re-exploration was required in four patients (bleeding in two, trocar-induced bowel injury in two). Immediate complications after surgery occurred in 20% of patients. Using endoclips, the cost was considerably reduced, from $400 to $290. The iliac fossa incision was aesthetically pleasing and more acceptable to patients. CONCLUSION These modifications are relevant in the context of a developing nation, as they provide all the benefits of LLDN at reduced cost and with better cosmetic results.

Abstract
The main objective was to determine the clinical and radiological features of metanephric neoplasms. The tumors were diagnosed on histopathological examination. The clinical data and imaging features were retrospectively analyzed. Between 1998 and 2003, 3 patients underwent radical nephrectomy for renal masses turning out as metanephric neoplasms on histopathology. Two of these tumors were metanephric adenoma (MA) and one was metanephric adenofibroma (MAF). Clinical and radiological features were reviewed. All patients were adult females who presented with flank pain. Tumor was detected on screening ultrasound as a hyperechoic lesion. In all cases CT showed a hyper-attenuating exophytic lesion with cystic areas that enhanced with IV contrast. Based on combination of clinical and imaging features it may be possible to prospectively identify metanephric neoplasms and thus avoid unnecessary radical nephrectomy in favor of conservative surgery.

Abstract
BACKGROUND The clinico-pathological characteristics of renal pelvic malignancies associated with stones were retrospectively analyzed. AIMS The main objective was to define the biological behavior and prognostic factors for these malignancies. SETTINGS & DESIGN The tumors were classified according to the pathological types. The clinical data, imaging features and pathological features were analyzed with relation to prognosis. MATERIAL AND METHODS Eighteen cases of malignancies associated with stone disease were retrospectively studied. The institute review board permitted the study. RESULTS High incidence (15/18) of squamous cell carcinoma (SCC) was noted. The prognosis in this group of patients was uniformly poor. The median survival time was 3.6 months in the SCC group, 7.5 months in the Transitional Cell Carcinoma (TCC) group and 24 months in the Adenocarcinoma (AC) group. Infectious and systemic symptoms were noted in the majority of the patients. Preoperative Imaging techniques revealed tumor in only 2 cases. Both underwent radical extirpation and the median survival is 18 months till date. In the other 16 patients, where the initial diagnosis was made only on histological analysis of incomplete nephrectomy specimens, the survival was 3.56 months. All patients had prolonged history of staghorn stone disease with associated non-functioning kidney. We found that the main prognostic factor was the stage of the disease. CONCLUSIONS Malignancies associated with stone disease have insidious onset of clinical symptoms and need a high degree of suspicion to identify them pre-operatively. The grave prognosis associated with incomplete excision makes it imperative to diagnose them earlier.

Abstract
Isradipine, 2.5 mg twice daily and placebo were administered for 4 weeks to 11 untreated essential hypertensives in a double-blind, random order, crossover study. At the end of each phase patients were assessed by 36 h of continuous intra-arterial blood pressure monitoring, surface electrocardiography, and measurement of endogenous creatinine clearance, serum biochemistry and plasma renin activity. Arterial pressure was significantly reduced by isradipine, with mean reduction in systolic blood pressure of 11.0 mmHg and diastolic pressure of 13.2 mmHg over 24 h. There was no significant change in heart rate, endogenous creatinine clearance, serum biochemistry or plasma renin activity.

Abstract
The clinical effect of a low-dose rapid-infusion intravenous regimen was assessed using human recombinant tissue-type plasminogen activator (rt-PA) in unstable angina. Fifty patients with unstable angina pectoris were randomly assigned to blinded treatment with either placebo (24 patients) or low-dose (20 mg bolus, 30 mg infusion over 1 hour) intravenous rt-PA (26 patients). Before randomization, all patients were treated with aspirin, twice-daily subcutaneous heparin, and maximally tolerated antianginal therapy. Of the 50 patients assigned, 26 received rt-PA and the outcome was successful in 15 (58%) (angina settled, no myocardial infarction or urgent intervention) compared with 9 (38%) successful outcomes in the 24 who received placebo (0.5 greater than p greater than 0.1). Angina remained refractory in 8 (31%) of the rt-PA group and in 13 (54%) of the placebo group (0.1 greater than p greater than 0.05). Urgent interventions were required in 6 patients (23%) who received rt-PA and in 11 patients (46%) who received placebo. Three patients in each group sustained a myocardial infarction within 72 hours of entering the trial and there were 3 deaths (1 in the active treatment group, 2 in placebo group) within 2 weeks of the trial (p = not significant). Administration of intravenous rt-PA was not associated with any complications. Low-dose rt-PA administration in patients with unstable angina was associated with a tendency to stabilization of anginal symptoms and a reduction in the need for urgent intervention. However, these trends did not achieve statistical significance.
