Mamun","doi":"10.3329/jdmc.v30i1.56899","DOIUrl":"https://doi.org/10.3329/jdmc.v30i1.56899","url":null,"abstract":"Background: Pemphigus vulgaris is an autoimmune, potentially fatal vesiculobullous disease of skin and mucous membranes. The clinical profile and epidemiologic characteristics varies in patients to patients and in different communities. The aim of this study was to evaluate the clinical and epidemiological features, morbidity and mortality of pemphigus vulgaris and to compare that with other studies of different communities.\u0000Methods: It was an observational study, conducted on 24 hospital admitted cases of pemphigus vulgaris at the department of Dermatology and Venereology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. The duration of the study was from November 2018 to February 2020. Patients who were confirmed as pemphigus vulgaris both histopathologically and direct immunofluroscent test were included for that study.\u0000Findings: The mean age (SD) of the patients was 47(15.5) years. Male outnumbered female in that study and male to female ratio was 1.4: 1. The mean (SD) duration of disease was 15(18.6) months. Pain (70.8) was the commonest symptoms. Trunk (92%) was the commonest cutaneous site of involvement followed by oral mucosa (71%). Oral prednisone was the mainstay of treatment and it was given to 24 (100%) of the patients. The immunosuppressant adjuvant was given in 79% cases. Azathioprine (62.5%) was the commonest of them. To avoid osteoporosis calcium supplement with or without vitamin D and bisphosphonate was given in 92% cases. The mean (SD) hospital stay was 5.4(3.3) weeks. Bacterial infection was the commonest complication and it was found in 2 patients. The mortality rate of that study was 4.16%.\u0000Conclusion: pemphigus vulgaris is a dermatological emergency and the maximum patients need hospitalization for proper care. Hospital acquired infections are the common complication and that may leads to septicemia and death. To decrease the mortality of pemphigus vulgaris the care givers have to be more watchful about the potential of infections.\u0000J Dhaka Med Coll. 2021; 29(1): 24-30","PeriodicalId":320976,"journal":{"name":"Journal of Dhaka Medical College","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124228857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adverse outcome following acute stroke depends not only on severity of the neurological defects but also on other co-morbidities. Associated renal impairment has been found to be a major predictor of different outcome following acute stroke in several studies. The aim of this study was to evaluate the impact of the serum creatinine on the outcome of hospitalized patients after acute stroke.\u0000Methods: This was a Prospective cohort study conducted on 100 consecutive adult patients who were admitted in the Neurology department of Dhaka Medical College Hospital following acute stroke during January 2018 to December 2019.The patients were followed up for two weeks after the incident stroke.\u0000Results: Among the 100 patients with acute stroke 57(57%) were ischaemic and 43(43%) were haemorrhagic stroke. Mean age(SD) was 60.4(10.6) years. Patients with ischaemic stroke were older compared to haemorrhagic stroke (61.1(9.6); 53.8(9.4) years respectively; p<0.05). The mean (SD) serum creatinine on admission in patients with both types of stroke, who deteriorated or died, were significantly higher than in those who survived. Others predictors of mortality and morbidity in both types of acute stroke were age, gender, hypertension, diabetes mellitus, ischemic heart disease, dyslipidaemia.\u0000Conclusions: Patients with impaired renal function had worse outcome after hospitalization in both types of acute stroke. Haemorrhagic stroke, older age, high baseline serum creatinine, hypertension were significantly associated with increased mortality and morbidity following acute stroke. Appropriate measures should be taken to patients with impaired renal function to reduce the mortality and morbidity following acute stroke.\u0000J Dhaka Med Coll. 2021; 29(1): 16-23","PeriodicalId":320976,"journal":{"name":"Journal of Dhaka Medical College","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122950816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients were included in this study who were healthy previously and developed acute kidney injury (serum creatinine >70.72 mmol/l) due to pregnancy related complications. Recruited patients were monitored after 3 months with a view to exclude chronic kidney disease.\u0000Result: A total of 351 patients with pregnancy and puerperium were observed, of these patients studied, 34 (9.2%) had pregnancy-related AKI. In 32 patients who completed the study, the mean age was 27.2±6.2 years. There were more subjects belonging to the rural area (68.8%) and nineteen (59.4%) of patients were below primary level of education. Most of the study subjects from lower socioeconomic status (56.2%). Twenty-one (65.5%) patients were multigravida, and mean parity of the patients included in this study was 1.7±0.8. Nineteen (59.4%) patients did not receive any antenatal care. PRAKI occurred during the post-partum period in 53.2% of the cases, 21.9% in third trimester, and 24.9% in first and 2nd trimester. The most common cause of PRAKI in our study was sepsis, occurring in about 15 patients (46.9%). Most common presentation of PRAKI was oliguria (87.5%) and edema (84.3%). Mean hemoglobin level was 7.8 ±1.7 gm/dl and creatinine level was 573±407 μmol/l. A majority of the patients (81.25%) underwent hemodialysis, while others were treated with conservative management only. At the three-month follow-up, complete resolution of AKI was observed in 62.5% patients, progressed to CKD in 25% whereas mortality occurred in 12.5% patients. In univariate analysis, inappropriate antenatal care (p- 0.0018), low mean platelet count (p-0.00001), higher serum creatinine (p-0.00004), dialysis at presentation (p-0.0154), and septicemia (p-0.0487), have significant effect.\u0000Conclusion: Pregnancy related AKI is still a critical situation in developing countries and rare entity in developed countries. Maternal mortality has decreased but sepsis still accounts for majority of cases of PRAKI.
