Seropositivity of dengue cases at a tertiary care centre in Chhindwara, Madhya Pradesh: A three year trend.

Background: During the recent decades, dengue virus infection has been emerged as a major public health problem. Dengue is one of the important mosquito borne infections causing high mortality and morbidity of humans. Methods: This study was carried out from October 2018 to December 2020. A total of 354 serum samples of clinically suspected dengue patients were tested for immunoglobulin M (IgM) anti-dengue antibodies by dengue monoclonal antibody capture enzyme-linked immunosorbent assay (NIV DEN IgM Capture MAC ELISA). Seasonal variations, age and sex wise incidences were also determined. Results: Total of 354 serum samples were processed from October 2018 to December 2020. Each year males were mostly infected with Dengue 08, 10, and 03 in 2018, 2019, and 2020, respectively. Age group 11-20 was found to be mostly infected by Dengue in case of both male and female. The prevalence of Dengue in each year was from July to November might be due to the rainy season. Clinical characteristics of patients such as fever, headache, abdominal pain and nausea/vomiting, retro-orbital pain, epistaxis, petechiae, altered sensorium, positive tourniquet test were reported. Conclusions: Continuous dengue virus surveillance is required for monitoring of dengue virus so that early detection can be carried out. Effective vector control measures should be implemented for early detection of impending outbreak and to initiate timely control measures.

Toxic thyroid adenoma with hypercalcemia mimicking an intra-thyroidal parathyroid adenoma.

Hypercalcemia is a clinical condition characterized by elevated circulating serum calcium levels either due to raised parathyroid hormone in hyperparathyroidism or due to secondary causes of hypercalcemia without elevated parathyroid hormone levels. However, hyperthyroidism may occasionally present with incidentally detected hypercalcemia. We present a case of a 53-year-old woman with a previous history of an underlying thyroid disorder, now presented with features of hypercalcemia and mildly elevated parathyroid hormone levels. Her ultrasonography of the neck was suggestive of an intra-thyroidal parathyroid adenoma and it was localized as a tracer avid lesion within the thyroid gland on dual-phase 99mTc-sestamibi planar scintigraphy with single photon emission computed tomography/ computed tomography (SPECT/CT). However, a subsequent thyroid profile followed by 99mTc- pertechnetate thyroid scintigraphy showed a hot nodule in the thyroid gland which changed the diagnosis to a toxic thyroid adenoma. She was treated with radioactive iodine ablation and thyrotoxicosis resolved and the serum calcium levels normalized on her follow-up.

Posttraumatic Scab on 131I Whole-Body Scan-A False-Positive Finding.

ABSTRACT: 131I scan plays a crucial role in the management of patients with differentiated thyroid cancer for the evaluation of remnant thyroid tissue, residual/recurrent metastatic disease, posttherapy tracer distribution, and response assessment to high-dose 131I therapy. Different causes secondary to physiological, pathological, and anatomical variations have been described for false-positive findings in the whole-body planar images. This case report of a patient of differentiated thyroid cancer with undocumented trauma to the left knee region a day before receiving the high-dose radioiodine therapy showed an interesting image finding of tracer uptake at unusual site in the posttherapy whole-body 131I scan.
