RESUMO

Objective: To evaluate the efficacy and complications of 20 gauge vitrectomy via corneal approach for the management of congenital cataract


Method: We performed anterior capsular vitreorhexis, lens matter aspiration [LMA], primary posterior vitrectorhexis and anterior vitrectomy via corneal approach using 20 gauge vitrectomy system in children younger than two years of age with congenital cataract between January 2014 to December 2014. The intra and postoperative complications were observed


Results: Twenty nine eyes of 21 children were included in this study. Congenital cataract surgery using 20 gauge vitrectomy system via corneal approach did not reveal any intra operative complication. Post operatively all children were able to freely open their operated eyes. Conjunctival congestion at the incision site in four eyes and mild anterior chamber reaction in 8 eyes were seen on 1[st] day which resolved at one week follow up. Other major post operative complications such as inflammatory membrane, irregular pupil, posterior/anterior syneache and opacification of visual axis were not seen during follow up period


Conclusion: The 20-gauge vitrectomy system via corneal approach is easy to perform, is less time consuming, safe and effective for the management of congenital cataract in younger children

RESUMO

Entamoeba histolytica [E. histolytica] produces an invasive disease called amoebiasis, which commonly produces diarrhea with or without blood in both children and adults, leading to high morbidity and mortality. Entamoeba dispar [E. Dispar] is a noninvasive, nonpathogenic organism. Both Entamoeba histolytica and Entamoeba Dispar look alike on microscopy and therefore cannot be differentiated unless checked on ELISA, PCR or other specific method. To calculate the actual prevalence of pathogenic amoebiasis in children by comparing the stool microscopy with ELISA stool antigen i.e. gold standard. Across sectional, comparative study. Children under five years in a community village Budhni, District Peshawar. A sample of 288 children aged <5 years were randomly selected. Information's were collected on the age and gender of the children. Fresh stool specimens were examined microscopically and with stool antigen kit of ELISA for detection of Entamoeba histolytica. The specificity and sensitivity of microscopic method was calculated against ELISA. Data was analyzed using statistical computer software package SPSS version 10.0. A total of 288 stool specimens were collected and examined for Entamoeba histolytica. Out of these 36[12.5%] stools were positive for E. histolyticaon microscopy while 14[4.9%] were positive on ELISA. Out of 14 ELISA positive samples, 10 samples were also positive on microscopy while 4 were ELISA positive but microscopy negative. About 22 samples, which were positive on microscopy were negative on ELISA indicating that these samples might have been of E. Dispar which is nonpathogenic protozoa. The sensitivity and specificity of microscopic method was 71.4% and 90.5% respectively, as against stool antigen test. Actual prevalence of Entamoeba histolytica is low in the area. Stool ELISA was able to differentiate between pathogenic Entamoeba histolytica and the non-pathogenic Entamoeba dispar and thus can minimize unnecessary antiamoebic treatment in these children

RESUMO

To compare the proportion of urinary symptoms in pre and postmenopausal women with Uterovaginal prolapse. Comparative Study. The study was carried out at the Department of Obstetrics and Gynecology Unit II, Dow University of Health Sciences and Civil Hospital Karachi from July 2005 to January 2006. Sixty consecutive patients [30 premenopausal and 30 postmenopausal] were included in the study through structured Proforma from the out patient ward or emergency. Informed consent was obtained. A detailed history and related examinations and investigations were done. These include urine DR, Urine C/S and Urodynamic like Cystometry in selected patients. In this study the difference of urinary symptoms in pre and postmenopausal women of Uterovaginal prolapse were statistically found insignificant like frequency of urine [26.7% versus 33.3%], Urgency [20% vs 26.7%], Nocturia [26.7% vs 13.3%], Dysuria [40% vs 26.7%], Voiding problems [40% vs 46.7%] Urge incontinence [40%vs 20%]. Stress incontinence was slightly higher in postmenopausal group than premenopausal [53.3%vs 46.7%] but this difference was found insignificant, while parity status between these two groups had significant difference like parity 2-5 was higher in pre-menopause group than postmenopause [66.7% vs 36.7%] and parity 6-10 was higher in postmenopause group than pre-menopause [63.3% vs 26.7%]. Significant difference in parity was found between pre and post-menopausal women with Uterovaginal prolapse but the difference of urinary symptoms in pre and postmenopausal group was found significant. Uterovaginal prolapse associated with different urinary symptoms especially incontinence and voiding problems. These urinary symptoms effect over quality of life of women.

RESUMO

An adequate blood pressure is a treatment of hypertension and it is the risk of cardiovascular morbidity and mortality so proper therapy is essential. Combination therapy of amlodipine plus atorvastatin improved vascular compliance, an indicator of structural and functional vascular changes, and the beneficial effect on small arteries appeared to be more than additive. This study aimed to evaluate the efficacy and biochemical effects of once-daily optimized Amlodpine/Atorvastatin 5/10 mg [F-6] versus placebo. placebo-controlled, comparative study. This study conducted in the Department of Biochemistry, University of Karachi from July 2010 to January 2011. This was multicenter, randomized, placebo-controlled, comparative study. Patients were selected from different hospitals of Orangi Town Karachi and samples were analyzed in the department of Biochemistry, University of Karachi. Patients were randomized to receive optimized Amlodpine/Atorvastatin 5/10 mg [F-6] once daily and Placebo once daily for 8 weeks. The efficacy and biochemical effects variables were change from baseline at the end of study which was evaluated. In the patients treated with optimized Amlodipine /Atorvastatin 5/10mg tablets' [F-6] alone, blood pressure reduction was lower, although significant, reaching values of 136.9 +/- 10.7 / 88.2 +/- 6.3 mmHg [p < 0.05 versus Placebo] by the end of eight weeks of treatment. Thus, the drug regimens used may be considered neutral as regards glucose and significantly reduce LDL-Cholesterol. Due to the high antihypertensive efficacy and hypolipidemic and no biochemical effects of the optimized Amlodipine/Atorvastatin 5/10 mg [F-6] it is an excellent option for the treatment of hypertension and hyperlipidemia patients, with a high potential to reduce cardiovascular risks

RESUMO

Hypertension is one of the strongest modifiable risk factors for cardiovascular and kidney disease and has been identified as the leading risk factor for mortality. The reduction of blood pressure lower than 130/85 mmHg provides additional benefits regarding both protection of organs and cardiovascular mortality. Angiotensin converting enzyme inhibitors have been shown to block the activation of the renin-angiotensin system in the plasma as well as in the vascular wall. The objective of this double-blind, comparative study evaluating the biochemical effects of optimized Ramipril 1.25 mg tablet as monotherapy in adult patient with essential hypertension. Double-blind, comparative study. This study was conducted at the Department of Biochemistry, University of Karachi from January 2011 to August 2011. This was multicenter randomized, double-blind, comparative study. Patients were randomized to receive Ramipril [1.25 mg] once daily for 8 weeks and at the end of study biochemical evaluation was done. In the patients treated with optimized Ramipril 1.25 mg tablets showed antihypertensive property. No significant variations of blood glucose and different parameters of lipid profile were observed during the eight weeks of treatment. We can suggest that the high antihypertensive efficacy, good tolerability and no biochemical effects of the optimized Ramipril 1.25 mg [F-4] it is an excellent option for the treatment of hypertension in a wide range of hypertensive patients, with a high potential to reduce cardiovascular risks

RESUMO

Despite advances in the prevention and treatment of hypertension over the past decade, hypertension remains an important public health challenge. Recent efforts to reduce the prevalence of hypertension have been focused on non-pharmacologic means, specifically diet. An increased intake of magnesium has been shown in some but not all studies to reduce blood pressure in patients with hypertension. Decreased Serum magnesium levels are associated with development of hypertension. This study was planned to investigate relation of serum magnesium with blood pressure in patients with mild uncomplicated hypertension. Study was conducted at LUMHS hospital Jamshoro and DHQ hospital charsadda for the period of six months. Fifty known cases of uncomplicated mild hypertensive patients were selected, same number of healthy controls were also examined. When results were summed up and test parameters were compared, it was seen that no significant differences were found in serum magnesium levels among both groups, when compared statistically. Finally we conclude that no relation of magnesium with hypertension was observed. Much more work on wide scale population may be needed to clarify the idea

RESUMO

The present work was designed to study the incorporation of newly synthesized myosin alkali light chain [MLC] molecules into myofibris. cDNA of fast skeletal muscle type of MLC tagged with green fluorescence protein [LC3f-GFP] was transfected into cultured chicken cardiomyocytes, and the assembly of expressed LC3f-GFP was observed in living cells under a fluorescence microscope equipped with a cooled CCD camera. At 14-16 hours after transfection, LC3f-GFP was diffusely distributed in the cytoplasm of cardiomyocytes. In some cells, however, intense fluorescence spots of LC3f-GFP were found along myofibrils with a periodically of 1.2 micro m. Confocal microscopy of such cells, stained with rhodamine-labeled phalloidin, revealed the fluorescence spots of LC3f-GFP localized at both ends of A-bond. When these cells were further incubated, LC3f-GFP came to be localized at all levels of the A-bands by 26 hours after transfection. These results indicate that myosin filaments are not replaced with newly synthesized myosin molecules at once along their length, but molecules in filaments are replaced individually from their ends
