Knowledge, attitude, and practice regarding treatment of group a beta haemolytic tonsillo pharyngitis and prevention of rheumatic fever among doctors in Karachi, Pakistan: A perspective study.

OBJECTIVE: To assess knowledge and practices associated with rheumatic fever among medical practitioners in an urban setting. METHODS: The cross-sectional study was conducted at five major hospitals in Karachi from August to November 2019, and comprised house officers, postgraduate trainees, and general physicians of either gender. The subjects were given a questionnaire assessing their knowledge and perception regarding acute rheumatic fever as well as prophylaxis. Data was analysed using SPSS 25. RESULTS: Of the 247 respondents, 173(70%) were house officers, 31(13%) were postgraduate trainees and 43(17%) were general physicians. Overall, 202(82%) subjects were associated with some teaching hospital. Significantly more postgraduate trainees and general physicians answered correctly when asked to identify clinical and laboratory findings suggestive of Group A streptococcal throat infection than house officers (p<0.001). Among the house officers 49(28.3%), and among the postgraduate trainees 11(35.4%) knew the correct way to prescribe penicillin to prevent rheumatic fever. Among the general physicians, 20(46.5%) had accurate knowledge regarding the prescription. CONCLUSIONS: Knowledge and practices of medical practitioners regarding rheumatic fever were less than ideal and may play a part in misdiagnoses of Group A streptococcal infections and, hence, prophylaxis.

Role of C- reactive proteins and liver function tests in assessing the severity of dengue fever.

OBJECTIVE: To determine whether C-reactive protein and liver function tests can serve as severity markers for dengue fever. METHODS: The cross-sectional study was conducted in 2015-16 in Karachi and comprised patients with dengue fever visiting a tertiary care hospital. World Health Organisation classifications 1997 and 2009 were used to categorise patients according to clinical signs and symptoms. Receiver Operating Characteristics curve was used to determine discriminative ability and optimum cut-off value of biochemical markers. Comparisons were done through one-way analysis of variance using SPSS 17. RESULTS: Of the 218 patients, 133(61%) were males and 85(39%) were females. The overall mean age was 35.07±15.96 years. Levels of C-reactive protein and total bilirubin were significantly higher for dengue haemorrhagic fever compared to dengue fever; dengue shock syndrome compared to dengue fever; dengue shock syndrome compared to dengue haemorrhagic fever; and dengue shock syndrome compared to dengue fever / dengue haemorrhagic fever (p<0.05 each). Levels of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase were significantly higher for dengue shock syndrome compared to dengue fever; dengue shock syndrome compared to dengue haemorrhagic fever; and dengue shock syndrome compared to dengue fever / dengue haemorrhagic fever (p<0.05 each). Levels of C-reactive protein, total bilirubin, alanine aminotransferase and alkaline phosphatise in patients with severe dengue were significantly higher compared to non-severe dengue. CONCLUSIONS: C-reactive protein and liver function tests were found to be effective biochemical markers in assessing dengue fever severity.

Perception and practices regarding cannabis consumption in Karachi, Pakistan: A cross-sectional study.

Several studies have been carried out regarding the awareness and usage of cannabis around the world, especially in developed countries. Pakistan ranks amongst the top nations in regards to cannabis consumption. However, the amount of literature shedding light on people's perception, knowledge and practices are scarce. Therefore, the authors sought to establish a baseline study to ignite the discussion on the possibility of cannabis' induction in the medical field in Pakistan, and additionally provide a foundation for further research. The purpose of this study was to investigate the level of understanding and consumption practices in Karachi with respondents from different socio-economic backgrounds, age groups and gender regarding cannabis use and assessing the awareness of the general population. The null hypothesis is that the usage of cannabis does not have a significant correlation with age, gender, or socio-economic status of a population. We conducted a cross-sectional study in November 2018 using convenience sampling and interviewed 518 individuals for their gender, age, and socio-economic status, to determine their knowledge, attitudes, and practices regarding cannabis usage. The participants were questioned about their knowledge and its source. Attitudes were judged using three and five-point Likert scales while questions regarding practices centered upon the past and current usage of cannabis. One-way analysis of variance and chi-square tests were used as the primary statistical tests. Out of the 518 people who responded, more than half of the respondents were males (n = 340, 65.6%). The majority was familiar with the use of cannabis (n = 514, 99.2%), and the different ways in which it is consumed (n = 435, 84%). About one-third of the participants happened to consume cannabis (n = 168, 32.4%), and a quarter mentioned recreational use/curiosity as the principal reason (n = 134, 25.9%). Majority of the respondents agreed upon the harmful effects of consuming cannabis (n = 364, 70.3%), while when compared to other inimical drugs, half of them believed it to be less harmful (n = 259, 50%). Besides, an overwhelming majority stated, that if they were to consume cannabis, they would not consider taking permission from their parents/guardians (n = 441, 85.2%). Concerning legality, three-fifths of the participants chose cannabis to remain illegal in Pakistan (n = 307, 59.3%) and, for not consuming/quitting cannabis, the primary reason chosen was its harmful consequences (n = 210, 40.5%). Our study revealed that knowledge about usage of cannabis still requires a great deal of attention. Only individuals from higher socio-economic backgrounds have a positive attitude towards cannabis usage and are aware of it. There is an urgent need for awareness programs that especially reach out to the lower socio-economic status population, who otherwise do not have access to essential information resources. We also found that males were more likely to be consumers and to have more knowledge about cannabis, therefore, it is equally important to educate females about this topic so that an informed discussion about cannabis use and its medical benefits can be generated in Pakistan.

Understanding The Rare Bone Tumor "ADAMANTINOMA".

Adamantinoma is a rare neoplastic bone tumor that has the potential to metastasize. The classic presentation is in the tibial region however; cases involving other bones of the body have been noticed. The tumour is very likely to be mistaken for other bone diseases and therefore it is important to investigate and study about its nature and thus differentiate it from other differentials. Nevertheless, literature on the presentation, findings, investigations and treatment options of adamantinomas are limited. In this case series, we report four cases from a local hospital in Karachi who were diagnosed, treated and followed up for adamantinoma. Studies regarding the disease will help us understand more about its features.
