A Study on Vitamin B12 Levels in Hypothyroid Patients Presenting to a Tertiary Care Teaching Hospital.

Background and aims The prevalence of vitamin B12 deficiency is found to coexist in hypothyroid patients, causing the persistence of symptoms concomitant to both diseases even on adequate thyroxine supplementation. Primary objective To study vitamin B12 levels in patients with hypothyroidism. Secondary objective To study the clinical profile of patients with hypothyroidism with special reference to anemia, and to study the association between vitamin B12 deficiency with anti-thyroid peroxidase (anti-TPO) antibodies and anti-thyroglobulin (anti-Tg) antibodies in patients with hypothyroidism. Methods and results A single-centric cross-sectional study was carried out over a period of one year. Among 100 hypothyroid patients, 68% were found to be vitamin B12 deficient, among whom 73.5% were females. Of patients with raised anti-TPO antibodies, 78.6% had vitamin B12 deficiency (p = 0.01), while 78% of patients with raised anti-Tg antibodies were vitamin B12 deficient (p = 0.07). The Pearson correlation coefficient (r) of vitamin B12 with anti-TPO and anti-Tg antibodies was -0.302 (p = 0.002) and -0.253 (p = 0.011), respectively. Conclusion There is a predilection of hypothyroid patients toward developing anemia, with vitamin B12 deficiency as a major etiology. This finding can be correlated with the hematopoietic action of thyroid-stimulating hormones as well as autoimmune thyroid disease predisposing to pernicious anemia.

A Study on Vitamin B12 Levels in Hypothyroid Patients Presenting to a Tertiary Care Teaching Hospital.

INTRODUCTION: Prevalence of vitamin B12 deficiency is occasionally found to be coexisting in patients with hypothyroidism causing persistence of symptoms concomitant to both diseases even on adequate thyroxine supplementation. MATERIALS: A single-centric non-interventional cross sectional study was carried over a period of 1 year. 100 hypothyroid patients were evaluated for prevalence of anemia, and investigated for the etiology. Serum Vitamin B12 was obtained and an association was studied between Vitamin B12 and anti TPO and anti Thyroglobulin antibodies. Here, vitamin B12 deficiency was defined as <160 pg/mL. RESULT: Among 100 hypothyroid patients, 31% were males and 69% were females. The mean age of patients was 36.09±12.864 years. 68% patients were found to be Vitamin B12 deficient, and 73.5% of this deficient population were females. 78.6% patients with raised Anti TPO antibodies had vitamin B12 deficiency (p-value = 0.01), while 78% patients with raised Anti Thyroglobulin antibodies were vitamin B12 deficient (p-value = 0.07). The Pearson correlation coefficient (r) was -0.302 (p = 0.002) and -0.253 (p = 0.011) between Vitamin B12 anti anti TPO and anti Thyroglobulin antibodies respectively, thus showing a negative correlation between both. CONCLUSION: Thyroid hormones affect erythropoiesis, thus causing anemia in a deficient condition. In iodine sufficient areas, most common cause of hypothyroidism is autoimmune, predisposing individuals to other autoimmune diseases, one being pernicious anemia. In the studied anemic hypothyroid population, Vitamin B12 deficiency was found correlated with raised levels of serum anti-TPO and anti-Thyroglobulin antibodies. Supplementation of B12 may alleviate hypothyroid symptoms, thus making itself a novel addition in the routine hypothyroid prescription. References Aon M, Taha S, Mahfouz K, et al.

Evaluation of point of entry surveillance for COVID-19 at Mumbai international airport, India, July 2020.

India started Point of entry (PoE) surveillance at Mumbai International Airport, screening passengers returning from coronavirus disease (COVID-19)-affected countries using infrared thermometers. We evaluated in July 2020 for March 1-22 with the Centers for Disease Control and Prevention evaluation framework. We conducted key informant interviews, reviewed passenger self-reporting forms (SRFs) (randomly selected) and relevant Airport Health Organization and Integrated Disease Surveillance Programme (IDSP) records. Of screened 165,882 passengers, three suspects were detected and all were reverse transcription-polymerase chain reaction negative. Passengers under-quarantine line-listing not available in paper-based PoE system, eight written complaints: 6/8 SRF filling inconvenience, 3/8 no SRF filling inflight announcements, and standing in long queues for their submission. Outside staff deployed 128/150 (85.3%), and staff: passenger ratio was 1:300. IDSP reported 59 COVID-19 confirmed cases against zero detected at PoE. It was simple, timely, flexible, and useful in providing information to IDSP but missed cases at PoE and had poor stability. We recommended dedicated workforce and data integration with IDSP.

Cholera outbreak in an informal settlement at Shahpur huts, Panchkula District, Haryana State, India, 2019.

In September 2019, after a reported death due to acute diarrheal disease in Shahpur village, Panchkula district, Haryana state, India, we conducted an outbreak investigation to identify the etiological agent, estimate the burden of disease, and make recommendations to prevent future outbreaks. The suspected cholera case was a resident of Shahpur huts, ≥1 year of age having ≥3 loose stools within a 24-h period between September 1 and 28, 2019 and a laboratory-confirmed cholera case, whose stool specimen tested positive for Vibrio cholerae. We identified 196 suspected cholera cases with a median age of 18 years (range: 1-65 years); 54% (106) being female. The overall attack rate was 8% (196/2,602), and the case fatality rate was 1% (2/196). Tested samples of water from tanks (n = 6), sewage effluent (n = 2), and 22% (4/18) of stool specimens collected from suspected cases were positive for V. cholerae. Strengthening surveillance, improving water, and sanitation systems are recommended to prevent future cholera outbreaks.

Outbreak of ceftriaxone-resistant Salmonella enterica serotype Typhi-Tiruchirappalli, Tamil Nadu, India, June 2018.

Objectives: In May 2018, a laboratory network for antimicrobial resistance (AMR) surveillance in Tamil Nadu, India, detected a cluster of Salmonella enterica serotype Typhi (S. Typhi) isolates resistant to ceftriaxone. We investigated to describe the epidemiology and identify risk factors for the outbreak. Methods: We conducted unmatched case-control studies. We defined a case as illness (fever with abdominal pain, diarrhea or vomiting) in a person with blood culture-confirmed ceftriaxone-resistant S. Typhi isolated between January 1 and July 4, 2018 in Tiruchirappalli, Tamil Nadu. We interviewed cases using a semi-structured questionnaire to identify common exposures to food, water and places visited. Results: We identified 7 cases (5 men) during March 25-June 8, 2018, median age 23 years (range: 12-42); all were hospitalized, none died. Eating at Restaurant A (odds ratio [OR]=22) and chicken gravy (OR=16) was associated with illness. Of the 10 workers at Restaurant A, stool culture from 8 did not detect S. Typhi; 2 did not consent to provide samples. Five water samples around the restaurant showed low or no residual chlorine content. Conclusions: The investigation highlights the value of AMR surveillance in detecting emerging pathogens and the need for timely investigations, along with strengthening food safety.

Disease surveillance during a large religious mass gathering in India: The Prayagraj Kumbh 2019 experience.

BACKGROUND: Mass gathering (MG) events are associated with public health risks. During the period January 14 to March 4, 2019, Kumbh Mela in Prayagraj, India was attended by an estimated 120 million visitors. An onsite disease surveillance was established to identify and respond to disease outbreaks. METHODS: A health coordination committee was established for planning. Disease surveillance was prioritized and risk assessment was done to identify diseases/conditions based on epidemic potential, severity of illness, and reporting requirement under the International Health Regulations (IHR) of 2005. A daily indicator and event-based disease surveillance was planned. The indicator-based surveillance (IBS) manually and electronically recorded data from patient hospital visits and collected MG area water testing data to assess trends. The event-based surveillance (EBS) helped identify outbreak signals based on pre-identified event triggers from the media, private health facilities, and the food safety department. Epidemic intelligence was used to analyse the data and events to detect signals, verify alerts, and initiate the response. RESULTS: At Kumbh Mela, disease surveillance was established for 22 acute diseases/syndromes. Sixty-five health facilities reported 156 154 illnesses (21% of a total 738 526 hospital encounters). Among the reported illnesses, 95% (n = 148 834) were communicable diseases such as acute respiratory illness (n = 52 504, 5%), acute fever (n = 41 957, 28%), and skin infections (n = 27 094, 18%). The remaining 5% (n = 7300) were non-communicable diseases (injuries n = 6601, 90%; hypothermia n = 224, 3%; burns n = 210, 3%). Water samples tested inadequate for residual chlorine in 20% of samples (102/521). The incident command centre generated 12 early warning signals from IBS and EBS: acute diarrheal disease (n = 8, 66%), vector-borne disease (n = 2, 16%), vaccine-preventable disease (n = 1, 8%), and thermal event (n = 1, 8%). There were two outbreaks (acute gastroenteritis and chickenpox) that were investigated and controlled. CONCLUSIONS: This onsite disease surveillance imparted a public health legacy by successfully implementing an epidemic intelligence enabled system for early disease detection and response to monitor public health risks. Acute respiratory illnesses emerged as a leading cause of morbidity among visitors. Future MG events should include disease surveillance as part of planning and augment capacity for acute respiratory illness diagnosis and management.

An outbreak of acute skin and soft tissue infections including necrotizing fasciitis in Kalwala village, India, 2018: Public health implications for the lymphatic filariasis elimination program.

BACKGROUND: A cluster of 15 acute skin and soft tissue infections (SSTIs), including two cases of necrotizing fasciitis, reported in July 2018 from Kalwala village, led us to investigate and describe their epidemiology and to provide recommendations. METHODS: Cases, defined as localized painful swelling and redness in Kalwala residents from 1 December 2017 to 20 August 2018, were identified from hospital records and house-to-house surveys. We conducted an unmatched case-control study to identify risk factors for severity. We cultured wound samples and environmental samples from wound-dressing stations. RESULTS: We identified 36 cases (median age: 55 [range 17-80] y; 78% male), village attack rate 1% (36/4337) and no deaths. In 34 cases (94%), lower limbs were involved. Lymphatic filariasis (LF) was a common predisposing condition (67%). Comorbidities (diabetes or hypertension) (OR=9; 95% CI 2.0 to 41.1), poor limb hygiene (OR=16; 95% CI 2.8 to 95.3) and poor health-seeking behavior (OR=5; 95% CI 1.6 to 30.8) were associated with severity. All seven wound samples and 8/11 samples from wound-dressing stations showed atypical polymicrobial growth (Pseudomonas, Proteus, Klebsiella, Escherichia coli and Clostridium). CONCLUSION: The outbreak of SSTIs among older males with LF was due to secondary bacterial infections and severity was associated with comorbidities, poor hygiene and health-seeking behavior, and likely contamination during wound-dressing. The LF elimination program managers was alerted, programmatic interventions were scaled up, home/facility-based morbidity and comorbidity management was facilitated and the outbreak was rapidly contained.

Concurrent Intramedullary and Intracranial Tuberculomass.

Tuberculosis of the central nervous system (CNS) is well known. CNS involvement can occur in the form of tubercular meningitis (TBM), tuberculous vasculitis, tuberculoma and rarely brain abscess. Tubercular granulomas generally solitary and occur in the brain but they may be multiple and involve other areas such as spinal cord, epidural space and subdural space also. Tuberculoma in the spinal cord is rare. Co-occurrence of intracerebral and intramedullary spinal tuberculoma is extremely rare in children with only few cases reported till date. We are reporting one such case in children and review of literature.

AIDS-related progressive multifocal leukoencephalopathy-really rare in India: A case report and review of literature.

Progressive multifocal leukoencephalopathy (PML) is a rare but devastating disease in acquired immuno deficiency syndrome (AIDS) patients. PML in HIV/AIDS is rare in India and literature is limited. We are reporting a case of probable AIDS-related PML from Antiretroviral Therapy (ART) Centre Jabalpur. It was our first case of PML (possible) in 3194 registered HIV patients taking ART since 2006.

Early Syringomyelia in Tubercular Meningitis.

Tubercular meningitis (TBM) can have various complications. Sometimes syringomyelia can also occur as a late complication of tubercular meningitis. Although syrinx formation in early stage of TBM is very rare. There are only four published case reports of syringomyelia in acute stage of TBM. Here we report a patient with tubercular meningitis who developed syringomyelia in early course of illness.

Spontaneous ventral spinal epidural hematoma in a child: A case report and review of literature.

Spontaneous spinal epidural hematoma is very uncommon cause of spinal cord compression. It is extremely rare in children and is mostly located in dorsal epidural space. Ventral spontaneous spinal epidural hematoma (SSEH) is even rarer, with only four previous reports in childrens. We are reporting fifth such case in a 14 year old male child. He presented with history of sudden onset weakness and sensory loss in both lower limbs with bladder bowel involvment since 15 days. There was no history of trauma or bleeding diasthesis. On clinical examination he had spastic paraplegia. Magnetic resonance imaging (MRI) of dorsal spine was suggestive of ventral spinal epidural hematoma extending from first to sixth dorsal vertebrae. Laminectomy of fourth and fifth dorsal vertebrae and complete evacuation of hematoma was done on the same day of admission. Postoperatively the neurological status was same.

Pneumocephalus in cerebellopontine angle and meningitis secondary to chronic otitis media in a child.

Pneumocephalus is a rare complication of chronic otitis media. Despite its rarity intra-cranial air carries a potential risk of increased intra-cranial pressure or meningitis, which requires immediate therapy. A 10-year-old child presented to us with complaints of fever, headache, vomiting, and decreased hearing from left ear. He had history of left ear discharge since 2 years. Clinical examination revealed neck rigidity and left chronic otitis media. Contrast enhanced computed axial tomography scan of head [Figures 1 and 2] showed pneumocephalus in left cerebellopontine angle, opacification of left middle ear and nonpneumatisation of left mastoid. Child was immediately put on empirical intravenous antibiotics and decongestants. He showed clinical improvement in 3 days. Pneumocephalus secondary to chronic otitis media is extremely rare; we are reporting one such case in a child with review of literature.

Spontaneous Resolution of Chronic Subdural Haematoma in a Patient Receiving Anticoagulant Therapy.

Significant chronic subdural hematoma (CSDH) is usually a surgical emergency. Spontaneous resolution of CSDH has rarely been reported in the literature. We are reporting a case of spontaneous resolution of CSDH in a patient receiving anticoagulant therapy who had undergone mitral valve replacement surgery.
