ABSTRACT
The study was undertaken from September 2018 to April 2019 to determine the prevalence of cutaneous leishmaniasis in human beings living in six districts of Karachi. Suspected persons were screened for the disease and positive cases were identified on the basis of skin lesions and blood samples. Samples were observed by mounting their smear. A total of 207 subjects of different ages and sex groups were investigated, however, only 192 (92%) of the suspected cases were found to have the disease 64% of cases were male which were significantly high (p<0.05), than female 36%. The lesion was more frequently detected among the youth ages of 21-30 years (31%) as compared to other groups. In both sexes, legs were found to be more infected (25% male + 20% female) followed by arms (20% male + 0% female) and face (15% male +11% female). The mixed body parts had shown the lowest infections such as (4% in males + 5%) in females. In conclusion, the highest and lowest leishmaniasis infections were observed in District West (23% male + 9% female) followed by District East (15% male + 7% female), District Malir (11% male+ 4% female), District Central (7% male + 5% female), District Korangi (4% male + 7% female) and District South (4% male + 4% female) respectively.
O estudo foi realizado de setembro de 2018 a abril de 2019 para determinar a prevalência de leishmaniose tegumentar em seres humanos que vivem em seis distritos de Karachi. Pessoas suspeitas foram rastreadas para a doença e os casos positivos foram identificados com base em lesões de pele e amostras de sangue. As amostras foram observadas montando seu esfregaço. Um total de 207 indivíduos de diferentes idades e grupos sexuais foi investigado, no entanto apenas 192 (92%) dos casos suspeitos foram encontrados para ter a doença; 64% dos casos eram do sexo masculino, que foram significativamente elevados (p < 0,05), e do sexo feminino 36%. A lesão foi detectada com maior frequência entre os jovens de 21 a 30 anos (31%) em comparação com os outros grupos. Em ambos os sexos, as pernas estavam mais infectadas (25% homens + 20% mulheres), seguidas pelos braços (20% homens + 0% mulheres) e rosto (15% homens + 11% mulheres). As partes mistas do corpo mostraram as infecções mais baixas (4% homens + 5% mulheres). Em conclusão, as infecções de leishmaniose mais altas e mais baixas foram observadas no Distrito Oeste (23% homens + 9% mulheres) seguido pelo Distrito Leste (15% homens + 7% mulheres), Distrito Malir (11% homens + 4% mulheres), Distrito Central (7% homens + 5% mulheres), Distrito Korangi (4% homens + 7% mulheres) e Distrito Sul (4% homens + 4% mulheres), respectivamente.

ABSTRACT
The study investigates the therapeutic potential of the Citrus aurantium var. amara essential oil extracted from the blossoms of the bitter orange plant by examining its chemical composition, thermal stability, and potency against infectious disease-causing pathogens. Initially, the volatile components of the essential oil were evaluated by obtaining a chromatographic fingerprint using HPTLC and FTIR spectrum identification. Furthermore, a thermal profile of the essential oil was obtained using the thermogravimetric-differential thermal analysis and differential scanning calorimetric analysis. A predetermined set of antibiotic-resistant microorganisms were used to examine the antibacterial activity of the essential oil. Lastly, its anti-inflammatory activity was assessed using the albumin denaturation assay. The research concluded that the Citrus aurantium var. Amara essential oil exhibits potential therapeutic characteristics which can be further explored through in vivo studies.
ABSTRACT
Objective: To evaluate anti-obesity effect of aqueous P. nigrum extract in a murine model of high-fat diet (HFD) induced obesity. Methods: Male Wistar rats were fed with a high-fat diet (HFD) (20g/day/rat) for a period of 50 d to induce obesity. Aqueous P. nigrum extract (20 mg/kg) administered orally to high-fat diet (HFD) fed rats from 8th day to 50th day (total 42 d). The parameters like gain in body weight, serum lipids, insulin and leptin were measured. Results: The rats treated with extract showed a significant reduction in body weight gain, serum insulin, leptin, lipids as compared to rats fed with only a high-fat diet (HFD). In addition, the extract-treated group showed a considerable rise in high-density lipoprotein (HDL-C) level (29.61±7.68 mg/dl) as compared to the control group (23.23±9.69 mg/dl). Conclusion: The results indicate that aqueous P. nigrum extract possess the potential to reduce obesity markers in a high-fat diet (HFD) fed rats.
ABSTRACT
Purpose: To evaluate the clinical factors associated with repeat Descemet stripping automated endothelial keratoplasty (DSAEK) or penetrating keratoplasty (PKP) in cases of failed DSAEK. Methods: Retrospective observational study of cases with failed DSAEK admitted to our center for a repeat keratoplasty over 5 years (January 2013–Decemeber 2017) was undertaken. Demographic and perioperative details of all cases and type of repeat keratoplasty were recorded. Logistic regression analysis was performed to analyze the factors affecting the type of repeat keratoplasty. Results: total of 94 eyes with failed DSAEK were evaluated. Repeat DSAEK was performed in 66% and PKP in 34% of cases. Significantly increased odds for requiring PKP were observed in association with stromal scarring [odds ratio (OR) = 2.9, P = 0.018)], trainee surgeons (OR = 4.05, P = 0.008), intraoperative complications (OR = 4.58, P = 0.003), scleral fixated intraocular lens or anterior chamber intraocular lens in situ (OR = 33.8, P < 0.001), secondary glaucoma (OR = 3.02, P = 0.015), peripheral anterior synechiae (OR = 8.6, P < 0.001), preoperative corneal thickness (OR = 1.01, P < 0001), time to primary surgery (OR = 1.03, P = 0.03), post-DSAEK host thickness (OR = 1.01, P < 0.001), and time interval from graft failure to regraft (OR = 1.18, P < 0.001). All eyes with congenital hereditary endothelial dystrophy, bee-sting-induced corneal decompensation, Axenfeld-Rieger syndrome, and multiple failed grafts underwent secondary PKP. All cases (nine eyes) that required surgical intervention for secondary glaucoma underwent secondary PKP (P < 0.001). Conclusion: Repeat DSAEK is feasible in up to two-third of cases of failed DSAEK. A PKP is required in one-third of cases, and various preoperative, intraoperative and postoperative factors are associated with unsuitability for repeat DSAEK.
