Scrub typhus meningoencephalitis, a diagnostic challenge for clinicians: A hospital based study from North-East India

Central nervous system (CNS) involvement is a known complication of scrub typhus which range from mild meningitis to frank meninigoencephalitis. Aims and objectives: To study the clinical feature, laboratory parameters and response to treatment of scrub typhus meningitis/meningoencephalitis. Methods and Materials: This is a hospital based prospective observational study from North Eastern India. Diagnosis was based on clinical features and positive serological test (Weils Felix test and IgM antibody card test). Results: 13 patients of scrub typhus with features of meningitis/meningoencephalitis were included. The mean duration of fever before presentation was 5.61±3.08 days and 4 (30.76 %) patients had eschar. Altered sensorium, headache, seizure and meningeal sign were present in 13 (100%), 13 (100%), 6 (46.15%) and 10 (76.92%) patients respectively. Mean CSF protein, glucose and Adenosine deaminase was 152.16±16.88mg/dl, 55.23±21.7mg/dl, and 16.98±7.37U/L respectively. Mean total count of CSF leukocyte and lymphocyte percentage was 46.07±131 cell/cumm and 98.66±3.09% respectively. Tablet doxycycline with or without injection azithromycin was used and that shows good response 15.38% of patients died and all of them had multi organ dysfunction. Conclusion: Meningoencephalitis is a common manifestation of scrub typhus and diagnosis requires high degree of clinical suspicion which if diagnosed early and specific treatment started, patients usually recover completely with few complications.

Are internet videos useful sources of information during global public health emergencies? A case study of YouTube videos during the 2015–16 Zika virus pandemic

ABSTRACT Background: Internet-videos, though popular sources of public health information, are often unverified and anecdotal. We critically evaluated YouTube videos about Zika virus available during the recent Zika pandemic. Methods: Hundred-and-one videos were retrieved from YouTube (search term: zika virus). Based upon content, they were classified as: informative, misleading or personal experience videos. Quality and reliability of these videos were evaluated using standardized tools. The viewer interaction metrics (e.g. no. of views, shares, etc.), video characteristics (video length, etc.) and the sources of upload were also assessed; and their relationship with the type, quality and reliability of the videos analyzed. Results: Overall, 70.3% videos were informative, while 23.8% and 5.9% videos were misleading and related to personal experiences, respectively. Although with shorter lengths (P < 0.01) and superior quality (P < 0.01), yet informative videos were viewed (P = 0.054), liked (P < 0.01) and shared (P < 0.05) less often than their misleading counterparts. Videos from independent users were more likely to be misleading (adjusted OR = 6.48, 95% CI: 1.69 – 24.83), of poorer (P < 0.05) quality and reliability than government/news agency videos. Conclusion: A considerable chunk of the videos were misleading. They were more popular (than informative videos) and could potentially spread misinformation. Videos from trustworthy sources like university/health organizations were scarce. Curation/authentication of health information in online video platforms (like YouTube) is necessary. We discuss means to harness them as useful source of information and highlight measures to curb dissemination of misinformation during public health emergencies.

Miliary tuberculosis with pulmonary and extrapulmonary component complicated with acute respiratory distress syndrome

Miliary tuberculosis results from the lymphohematogenous spread of the tubercle bacilli to the vascular beds in the lungs and other organs. Diagnosis is made by clinical judgment and chest X-ray showing miliary mottling of the lung fields. Another imaging study like computed tomography imaging of the lungs and abdomen can also be supportive in diagnosing miliary tuberculosis. We present a case of miliary tuberculosis in an immunocompetent young male with atypical manifestation of a left-sided pleural effusion and a life-threatening complication of acute respiratory distress syndrome during hospital stay which required noninvasive mechanical ventilation and steroids therapy, along with antitubercular medication.

Monoclonal gammopathy with double M-bands: An atypical presentation on serum protein electrophoresis simulating biclonal gammopathy

Monoclonal gammopathies, such as multiple myeloma, typically exhibit high levels of a monoclonal immunoglobulin (M-protein), produced by a clone of abnormally proliferating B-lymphocytes and/or plasma cells. The M-protein can be evaluated by serum protein electrophoresis (SPEP), which yields a single discrete band (M-band), usually in the γ-globulin region. Rarely, two M-bands appear simultaneously at different positions during SPEP – a condition known as biclonal gammopathy, which is a result of clonal expansion of two different neoplastic cell lines. Here, we describe an atypical case of IgA-λ multiple myeloma, where double M-bands (one in β- and the other in γ-globulin region) were found during SPEP simulating biclonal gammopathy, although it was monoclonal in nature. This peculiar presentation of double M-bands in monoclonal gammopathy was attributed to polymeric forms of IgA by systematic workup. Further, we discuss how true and apparent biclonality can be distinguished by inexpensive analytical techniques in resource-constrained settings.

Scrub Typhus Presenting with Bilateral Lateral Rectus Palsy in A Female.

Scrub typhus, a rickettsial disease is endemic in several parts of India usually presenting with acute symptoms. Fever, maculopapular rash, eschar, history of tick exposure and supportive diagnostic tests usually leads to diagnosis. Scrub typhus should be included in the differential diagnosis in occasions when a patient presents with fever with or without eschar and isolated cranial nerve palsy. Here we are reporting a case of Scrub typhus who presented with fever and altered sensorium of short duration, eschar formation and bilateral lateral rectus palsy. Patient was treated with doxycycline with complete reversal of neurodeficit.

Acute Pancreatitis in a Patient with Complicated Falciparum Malaria.

Malaria is one of the most common protozoan diseases, especially in tropical countries. The clinical manifestation of malaria, especially falciparum malaria varies from mild acute febrile illness to life threatening severe systemic complications involving one or more organ systems. We would like to report a case of complicated falciparum malaria involving cerebral, renal, hepatic system along with acute pancreatitis. The patient was successfully treated with anti malarial and other supportive treatment. To the best of our knowledge there are very few reports of acute pancreatitis due to malaria. Falciparum malaria therefore should be added to the list of infectious agents causing acute pancreatitis especially in areas where malaria is endemic.

A Study to Assess the Validity of Estimation of Serum Ostase Level in Hyperthyroid and Hypothyroid Cases.

INTRODUCTION One of the more specific assessments of the metabolic status of bone in normal and in disease conditions is the measurement of bone specific alkaline phosphatase or ostase. The measurement of serum ostase has several advantages over the measurements of other bone parameter. Because of its relatively long half-life, in-vivo (1 to 3days), it is relatively unaffected by diurnal variation. AIM To find the correlation of serum ostase level in hyper and hypothyroid cases and also to study the validity of routine estimation of serum ostase in hyper and hypothyroid cases so as to monitor the base level bone health on presentation. MATERIALS AND METHODS Serum ostase level was studied in 74 patients with disorder of thyroid function. Serum ostase level, Thyroid Stimulating Hormone (TSH), FT3, FT4 levels were estimated by chemiluminescent technique. The instrument used was Beckman- coulter Access 2. A total of 39 patients were hypothyroid, 31 were hyperthyroid and 4 patients had subclinical hyperthyroidism. RESULTS The serum ostase level was found to be elevated above 40 μg/L in 26 of the cases and above 16 μg/L but below 40μg/L in 5 cases of hyperthyroidism along with decrease in Bone Mineral Density (BMD). Serum ostase level was found to be directly proportional to the serum FT3 level (Normal range of serum ostase is 8-16 μg/L). CONCLUSION From this study, an inference can be drawn that a routine estimation of serum ostase level in hyperthyroid cases will help in proper monitoring of decrease bone turnover as indicated by increase serum ostase level. Besides, the estimation of serum ostase level in hyperthyroid cases it is found to be valid in this study, which can turn to be an important guiding parameter to the treating physician to formulate necessary protocols and guidelines for prophylaxis, treatment and to monitor the response to therapy in cases of reduced bone turnover related to hyperthyroid state.

Lutembacher’s Syndrome: A Rare Cause of Right Heart Failure

The Lutembacher’s syndrome is a rare, complex congenital heart disease, consisting of a congenital defect in the atrial septum (ostium secundum) along with acquired mitral stenosis. It is well established that early diagnosis and timely surgical treatment has good prognosis, while feasibility and safety of percutaneous treatment is demonstrated in few case reports. Key words: Mitral stenosis, Atrial septal defect, Congenital heart disease, Heart failure.

Hemophagocytic Syndrome Associated with Scrub Typhus: A Case Reportfrom North East India

Scrub typhus infection is an important aetiology of acute undifferentiated fever in south-east Asia and India. Haemophagocytic Lymphohistiocytosis (HLH) (haemophagocytic syndrome) is a potentially fatal hyper inflammatory syndrome that is characterized by histiocyte proliferation and haemophagocytosis. We describe a case of Haemphagocytic syndrome secondary to scrub typhus which presented with fever, rash, pancytopenia, epistaxis and haematuria who responded dramatically with respect to haematological parameters and clinically following prompt antimicrobial therapy. Scrub typhus with hemophagocytic syndrome can be complicated by multiorgan failure. Patients with scrub typhus usually have an excellent response to treatment; therefore, early diagnosis and prompt administration of antimicrobial therapy may prevent the development of serious complications.

Abdominal histoplasmosis mimicking tuberculosis in an immunocompromised patient

Histoplasmosis should be considered as a differential diagnosis especially in immune-compromised patients presenting with gastrointestinal symptoms even in areas where histoplasmosis is non endemic. The presenting symptoms often mimic abdominal tuberculosis. There are reports of simultaneous infections of both histoplasmosis and tuberculosis in patients with acquired immunodeficiency syndrome (AIDS). With early diagnosis and aggressive antifungal therapy gastrointestinal histoplasmosis has a very good prognosis. Here we are reporting a case that initially presented with clinical and radiological evidence initially suggestive of abdominal tuberculosis which on further work up was diagnosed as abdominal histoplasmosis.
