Tuberculosis (TB) and malignancy are among the most important current global health problems. Many authors suggest that their coexistence is a chance association owing to their high prevalence. There is, however, enough evidence that one condition may predispose the other. In our retrospective report of two cases, TB in draining lymph nodes was discovered incidentally on histopathology, following surgical resection for malignancy. The possibility of coexistent lesions, especially in regions endemic for TB, mandate a detailed histopathological examination to prevent the chances of diagnostic failure and thus therapeutic error...

Dengue is endemic in more than 100 countries, giving rise to an increased number of deaths in the last five years in the South-East Asian region. We report our findings from a retrospective study of adults admitted with confirmed dengue at our institution. We studied the clinical and laboratory parameters associated with mortality in these patients. Of the 172 hospitalised patients studied, 156 (90.69 %) recovered while 16 (9.3%) died. Univariate analysis showed altered sensorium on presentation, lower haemoglobin and haematocrit levels, higher serum creatinine, higher serum transaminase and lower serum albumin levels to be significantly associated with mortality in dengue...

In common with Zika, Chikungunya and Dengue, Yellow Fever (YF) is an arthropod-borne flavivirus. It is transmitted between humans and from monkeys by mosquitoes of the Aedes aegypti (its principal vector), haemogogus and albopictus varieties. Three cycles of transmission may occur: urban; sylvatic; and intermediate. Recently, sub-Saharan Africa has seen the resurgence of this neglected disease. The current YF outbreak in Angola began in December 2015 in the capital Luanda and by October 2016 there had been > 4300 suspected cases, with 376 deaths (case fatality rate = 8...

We report a case of expanded dengue syndrome, where three uncommon presentations occurred concomitantly. A patient with dengue haemorrhagic fever presented initially with acute acalculous cholecystitis along with acute pancreatitis, but later on, during resolution of pancreatitis and cholecystitis, developed pancytopenia, most likely due to haemophagocytic syndrome. Such presentations, besides being rare themselves, have not been reported to occur concomitantly, in the same patient, during the same disease process...

Dengue fever is of great concern to public health in India as it contributes significantly to the burden of healthcare. The aim of our study was to measure mortality in dengue and its association with hepatitis and thrombocytopenia. Our study was performed in a tertiary care setting in the state of Kerala in southern India. Adult patients admitted in the year 2013 were included. Among 1308 confirmed dengue patients, the mortality rate was 1.76%. Hepatitis and thrombocytopenia were present in over 80% of all patients, but severe hepatitis was seen in 11...

Much epidemiological information concerning brucellosis generally depends on the evaluation of hospital-based retrospective data. The aim of this study was to determine the prevalence and risk factors of brucellosis in female farmworkers in the south-eastern region of Turkey (GAP) in order to obtain a more representative analysis. Our representative community-based cross-sectional study was conducted during four months of 2013, in all nine GAP provinces. An optimum sample size was determined and blood samples were analysed from 707 reproductive-age female farmworkers using the Rose Bengal (RBT) and standard (SAT) agglutination tests...

A 30-year-old woman presented to our outpatient department with complaints of pain and swelling in bilateral infrapatellar regions and a discharging sinus in the right knee over the duration of one year. Radiographs showed lytic regions in bilateral patellae. Samples sent from material curetted from sinus yielded no organism but histopathology reported granulomatous inflammation. Following a fresh magnetic resonance imaging (MRI) scan that revealed the infrapatellar pad of fat communicating with the patellar lesions, an exploration and evacuation was done...

Leptospirosis has been recognised as an emerging global public health problem. The aim of our study was to explore the epidemiological and clinical pattern of disease occurrence in suspected cases and to search for any existing co-infections. Ours was a retrospective study in patients with acute febrile illness in north India over a period of three years (April 2011 to June 2014). Serological diagnosis of leptospirosis was made using the PanBio IgM ELISA kit. Using modified Faine's criteria, presumptive and possible diagnosis was made in 57% and 34% cases, respectively...

Infections are an important differential diagnosis in patients presenting with features of systemic vasculitis. We report a young lady with constitutional features, leg ulcers, digital gangrene and absent peripheral pulses with cervical adenopathy. Chest imaging revealed multiple necrotic lung lesions and involvement of left subclavian artery at its origin from the aorta, Histopathology from cervical lymph nodes showed multiple caseated lymph nodes, which in the context of a positive Mantoux test led us to diagnose tuberculosis and institute appropriate therapy...

Differentiation of small bowel tuberculosis (SBTB) from Crohn's disease (CD) is a diagnostic challenge. We studied 52 patients with suspected SBTB or CD with terminal ileal involvement, who were prospectively enrolled. After confirming patency of the gastrointestinal tract, 26 patients underwent capsule endoscopy (CE). A final diagnosis of CD was found in 18 patients and SBTB in eight patients. All SBTB patients had involvment of the ileocecal valve (ICV) with large (n = 6) and aphthous (n = 2) ulcers in the ileal segment...

Ours was a descriptive observational cross-sectional study carried out in a tertiary care hospital in eastern India over a period of one year to study the profile of neurological involvement in paediatric dengue patients. Of 71 laboratory-confirmed cases, 20 (28.17%) had neurological involvement. Common forms observed were acute encephalopathy (40%), encephalitis (30%), pure motor weakness (15%), transverse myelitis (5%), acute disseminated encephalomyelitis (5%) and Guillain-Barré syndrome (5%). The dengue IgM antibody could be detected in the cerebrospinal fluid of only two patients with encephalitis...

As original tribal ways of living have morphed from a forest dweller existence, dengue is no longer an urban infection but is now also found in rural hilly areas. The spread of dengue is enhanced by the frequent movement of people to endemic areas where there is a vector mosquito presence. The impact of the virus is known to be great in the immunologically naive population. Our study reports on the threat of the dengue virus in these hilly areas.

We sought to determine the incidence and clinical spectrum of the paradoxical reaction (PR) to treatment in 1000 children with tuberculosis (TB). Its incidence was 3.3%, presenting as mediastinal adenopathy (n = 12), central nervous system (CNS) tuberculoma (n = 8), increasing size of lymph nodes (n = 8) and serositis (n = 5). Symptoms included breathlessness (n = 7, 21.2%), neck swellings (n = 5, 15.2%), hemiplegia (n = 3, 9.1%), raised intracranial tension (n = 2, 6.1%) and fever or diabetes insipidus (n = 1, 3% each)...

The diagnosis of smear-negative pulmonary tuberculosis (PTB) is particularly challenging, and automated liquid culture and molecular line probe assays (LPA) may prove particularly useful. The objective of our study was to evaluate the diagnostic potential of automated liquid culture (ALC) technology and commercial LPA in sputum smear-negative PTB suspects. Spot sputum samples were collected from 145 chest-symptomatic smear-negative patients and subjected to ALC, direct drug susceptibility test (DST) testing and LPA, as per manufacturers' instructions...
