Hidden burden of chikungunya in North India; A prospective study in a tertiary care centre

BACKGROUND Arboviral diseases, such as chikungunya, dengue and now zika represent a public health problem, especially in tropical countries. Epidemiology of chikungunya and dengue is well known, including its social and climatic factors associated, but only few data and reports of chikungunya are available from North India. The clinical differentiation of chikungunya from dengue is no doubt challenging since both diseases can share clinical signs and symptoms leading to potential misdiagnosis of chikungunya in areas where dengue is endemic. The aim of this study was to know the seroprevalence, seasonal trends, clinical presentations of chikungunya and its co-infection with dengue virus. METHODS This was a prospective study conducted in Varanasi, from January to December 2016. All serum samples were tested for both chikungunya and dengue IgM antibodies by MAC ELISA test. RESULTS Total of 186 samples, out of which 108 (58%) samples were total seropositive, 23 (12.37%) samples positive for chikungunya IgM antibodies, 57 (30.65%) samples positive for dengue and 28 (15.05%) samples positive for both chikungunya and dengue. The most affected age group was 20-30 years and males were more affected than females. A seasonal peak for chikungunya and its co-infection with dengue were seen in November. CONCLUSION In India, the seroprevalence of chikungunya is increasing. India is a rapidly developing country where adequate sanitation is required. More aggressive intervention and vigilance by health authorities is needed to decrease vector born diseases.

Drug reaction with eosinophilia and systemic symptoms syndrome associated with Nitrofurantoin

Drug reaction with eosinophilia and systemic symptom (DRESS) is a severe adverse drug-induced reaction with a prolonged latency period which is characterized by a variety of clinical manifestations, usually fever, rash, lymphadenopathy, eosinophilia, and a wide range of mild-to-severe systemic presentations. Drugs are an important cause of DRESS in most of the cases. It is challenging to diagnose DRESS because of the diversity of cutaneous eruption and visceral organs involvement. We hereby report a 34-year-old female who developed DRESS syndrome following ingestion of nitrofurantoin for the treatment of urinary tract infection. She was managed conservatively and recovered after few weeks. Our aim of this study is to raise awareness to suspect DRESS syndrome in patients who present with unusual clinical features with skin involvement after initiating any drug.

Clinical profile of dengue fever and coinfection with chikungunya

Objective: Arthropod-borne viral diseases are a major burden on the health-care system worldwide. Only a few studies have reported on coinfection of dengue fever (DF) with the chikungunya virus in North India. We investigated the seroprevalence and significance of the clinicobiochemical profile of dengue and chikungunya coinfection. Besides this, the authors try to emphasize rationalize platelets transfusion. Material and Methods: The present study was conducted at the Heritage Institute of Medical Science, Varanasi, India, from July to December 2016. A total of 1800 suspected cases with acute viral febrile illness (age >18 years) were investigated to exclude other causes of acute febrile illnesses. Of these, 121 patients (6.72%) were diagnosed as seropositive for dengue and chikungunya mono or coinfection using IgM ELISA and were included in the study. Results: The male gender was predominant. The majority were in the 20–30-year age group with cases peaking in November. There were 102 (84.29%) cases of dengue, 6 (4.95%) cases of chikungunya, and 13 (10.74%) cases positive for coinfection. Fever was present in all cases. Headache followed by nausea/vomiting and generalized weakness were the most common symptoms in patients with DF while body aches and joint pain were most common in those with chikungunya fever. Deranged liver function and leukopenia were the most common complications in dengue. Conclusion: Joint-related symptoms (pain and restricted movements) were statistically significant in chikungunya monoinfection. Two patients with DF were died. There was no significant added severity of clinical features and blood investigations in patients with coinfection with dengue and chikungunya compared to those with monoinfections.

Positive outcome of pulmonary tuberculosis associated with extraordinary extensive extrapulmonary tuberculosis in an immunocompetent adult

Tuberculosis (TB) is known to cause a wide variety of complications and atypical presentations. It usually presents with typical symptoms. Here, we present the unusual case of pulmonary TB with the involvement of lungs, brain, liver, spleen, vertebra, skin, left cervical lymph nodes, bone marrow, and heart. It is unique with this case of disseminated TB presenting in squall and decimating manner involving many different organs simultaneously in an immunocompetent patient who was treated successfully with antitubercular treatment. According to literature review, this is the first case report of this type especially from an endemic country like India.

Self Mutilating Behaviour in Severe Meningococcal Infection; An Interesting Association

Neisseria meningitidis most commonly manifests as asymptomatic colonization in the nasopharynx of healthy adolescents and adults. It may rarely present as invasive disease which may be either bacterial meningitis or meningococcal septicaemia. Hereby we report a case presented with fever and rashes, irritability followed by self mutilating behaviour who was diagnosed as a case of invasive meningococcal infection. He responded well to treatment with intravenous ceftriaxone and self mutilating behaviour was subsided completely after treatment. Necrosed tissues of fingers were amputated. With best of our knowledge, no similar case of self-mutilation associated with meningococcal infection has been reported yet.
