A study of clinical and laboratory profile of dengue positive cases in hadoti region Rajasthan, India

 Background: Dengue fever is one of the most common arboviral mediated outbreaks reported with increased prevalence year after year with considerable morbidity and mortality in hadoti region. the aim to study various clinical and laboratory manifestations of Dengue fever admitted in MBS Hospital KOTA, with a diagnosis of Dengue fever according to WHO protocol from December 2018 to January 2020.Methods: Prospective observational study was undertaken among adult patients. 132 patients were studied and analysed. And diagnosis was confirmed with Dengue IgM ELISA test. Other routine investigations done were routine hematological and biochemical investigations.Results: A total of 132 cases, out of which 95 cases of Dengue Fever (DF), 34 cases of dengue hemorrhagic fever and 3 cases of Dengue Shock syndrome, out of which Male: Female ratio was 2.1. and mean age of presentation was 37. Fever and myalgia were the most common finding (100%) followed by arthralgia and headache. Pruritus was found in 21 cases (15.9%) which carried a significant difference between DF and DHF (p value <0.05). Among the laboratory features, thrombocytopenia and hematocrit were found to be statistically significant in DHF patients (p value <0.05). Mean platelet count was 0.71 lakhs/mm3. Leukopenia in 40(30.3%) cases. Raised Serum Aminotransferase level, AST (>40 IU/L) was seen in 39 cases (29.54%.). Pleural effusion was seen in 4 cases (3%), of which 3 cases of DHF and 1 case of DSS. Ascites in 6 cases (4.8%), all cases belong to DHF. Gall bladder wall thickening was seen in 28 cases (21.21%) of which 20 cases (54.04%) were of DHF. Melena was the most common bleeding manifestation. Skin rash was found to be positive in 40.5% cases. Hess test was positive in 4 cases (10.8% of DHF).Conclusions: Incidence of dengue fever is on the rise in hadoti region and one of the most important differential diagnosis of patients presenting with fever during monsoon and post monsoon seasons.

Epidemic of Scrub Typhus in Haroti Region of Rajasthan.

Scrub typhus is a rare form of disease caused by gram negative bacterium Orientia tsutsugamushi, of family Rickettsiaceae, transmitted by bite of infected trombiculid mite larva (chigger). The present prospective study is undertaken with the aim of the clinical manifestations, course, complications and outcome of scrub typhus in Haroti region of Rajasthan state during the recent epidemic. Method: This prospective study was conducted in indoor patients of MBS hospital and various private nursing homes in Kota city from August 2012 to November 2012. Twenty cases with positive Scrub typhus card test in the age group of 20 years to 60 years, comprising of 14 males and 06 females were included in the study group in clinically suspected cases with fever, rashes, cough with or without eschar and regional lymphadenopathy. Cases were studied in detail and followed up for improvement and any permanent damage or death. Results: Out of 20 patients, 16 patients improved and discharged from hospital in stable condition without any disability. 02 patients (10%) died because of late presentation and multiorgan involvement especially respiratory failure or meningoencephalitis. Conclusion: Haroti witnessed recent epidemic of Scrub typhus. Renal, respiratory and neurological complications were main cause of mortality and morbidity.

Aluminium Phosphide Poisoning.

Aluminium phosphide poisoning is a major cause of morbidity and mortality in northwest and central India. It liberates lethal phosphine gas when it comes in contact either with atmospheric moisture or with hydrochloric acid in the stomach. The mechanism of toxicity includes cellular hypoxia due to the effect on mitochondria, inhibition of cytochrome C oxidase and formation of highly reactive hydroxyl radicals. In India, most of the patients who come with Celphos poisoning succumb to its toxicity because of the considerable time gap between the ingestion of the poison and the initiation of proper treatment. This has led to widely prevalent scepticism among physicians while managing cases of Celphos poisoning. Due to no known specific antidote, management remains primarily supportive care. In most of the studies, poor prognostic factors were presence of acidosis and shock. The overall outcome improved in the last decade due to better and advanced intensive care management.

Impact on Morbidity & Mortality by Rodenticidal Poisoning.

Background : Rodenticidal poisoning is a very common clinical entity regularly encountered in outdoor & emergency department in various parts of India. This is the commonest type of poisoning. We present the prospective study of clinical profile, course, complication & outcome of various rodenticidal poisoning in 170 patients. Objectives : To determine the clinical symptoms, morbidity and mortality in various rodenticidal poisoning. To study the clinical profile & laboratory investigations. To study the course, complications & outcome. Methods : Study period was from 01 May 2011 to 30 April 2012. Historically and documented evidence of 170 patients of various rodenticidal poisoning admitted in the emergency, medical wards & I.C.U. under department of medicine, undergone for various laboratory investigations and imaging study. Statistical analysis was done in mean, range, standard deviation and percentage. Results : A total of 170 cases of various rodenticidal poisoning admitted in MBS hospital, Govt. Medical College, Kota were studied. The age of patients ranged from 10 to 65 years. Age groups were divided in four group, 10-18, 19-30, 31-45 & 45-65. Most common age group was ranged from 18-30 year. Most common gender was female (females 92 males 78). Mode of poisoning were suicidal, accidental & homicidal. Commonest mode of poisoning was suicidal uptake of poison. Route of poisoning was ingestion. Common presenting signs & symptoms were nausea & vomiting seen in 157(92.35%), Tachycardia in 156(91.7%), Tachypnoea in 137(80.62%), & Abdominal pain 129(75.8%). Few patients presented with Headache, Palpitation & Sweating. Deranged laboratory findings on day third of admission include Anemia in 21.76%, Leucocytosis in 20.59%, prolonged Prothrombin time (PT) in 16.47% & increased serum Bilirubin in 11.18%. Morbidity developed in 8 cases(4.71%), Of which four have Hemorrhagic complication ( e.g. Bleeding gums, Purpura Melena & Hematuria) by Dicoumarol , Bromadiolone and Brodifacoum. Three patients of Zinc phosphide poisoning produced cardiac insult and one patient of Barium carbonate poisoning developed cardiac arrhythmia. Transient arrhythmias and respiratory failure developed in other rodenticidal poisoning. All patients treated symptomatically and according to complications. Six cases of our study remained asymptomatic for two to three days then they developed delayed hemorrhagic complication ( Bleeding gums, Purpura, Melena & Hematuria). These patients had deranged liver function test (LFT) & prolonged Prothrombin time (PT). Mortality was seen in 1.76%( 3 cases). By Zinc phosphide in 2 patient and Barium carbonate in 1 patient. Conclusion : We concluded that bleeding, bruising & other hemorrhagic complications should be treated and monitored according to Prothrombin time (PT) & INR. Awareness should be increased especially for Zinc phosphide and arrhythmia produced by Barium carbonate.
