Inherently, brachytherapy is the most conformal radiotherapeutic technique. As an aid to brachytherapy, ultrasonography (USG) serves as a portable, inexpensive, and simple to use method allowing for accurate, reproducible, and adaptive treatments. Some newer brachytherapy planning systems have incorporated USG as the sole imaging modality. Ultrasonography has been successfully used to place applicator and dose planning for prostate, cervix, and anal canal cancers. It can guide placement of brachytherapy catheters for all other sites like breast, skin, and head and neck cancers...

PSMA PET is increasingly being used in imaging of recurrent prostate carcinoma. A case with suspected recurrent Prostate carcinoma (PCa), raised PSA (Prostate specific antigen) and suspected spinal metastases was referred for whole body Ga-68-PSMA PET/MRI. The study revealed PSMA avid recurrent prostate mass and extensive osseous metastases. Abnormal PSMA uptake in the thyroid gland prompted USG-guided FNAC which revealed Hurthle cell neoplasm. Histopathological examination (HPE) of excised gland showed multiple Hurthle cell adenomas in both lobes of thyroid along with foci of papillary thyroid carcinoma which on immunohistochemistry were thyroglobulin positive and PSA negative...

BACKGROUND: High proportion of TB in people living with HIV (PLHIV) is undiagnosed. Due to this active TB case finding is recommended for HIV clinics in high TB burden countries. Presently sputum examination and chest radiography are frontline tests recommended for HIV infected TB presumptives. Abdominal TB which occurs frequently in PLHIV may be missed even by existing programmatic intensified case finding protocols. This study evaluated the routine use of ultrasonography (USG) for active case finding of abdominal TB in HIV clinics...

Cervical pregnancy is a rare site of ectopic pregnancy compared to tubal. The trophoblast implant into the cervical tissue and become a potentially dangerous site of torrential haemorrhage. The widespread use of Ultrasonography (USG) has led to a dramatic increase in the detection rates of extra uterine pregnancy. We hereby report an interesting case of extra uterine pregnancy with a unique situation where only a high index of suspicion prevented an iatrogenic mishap. The patient was referred as a case of incomplete abortion with a documented report of minimal retained products...

RATIONALE: Determination of non-exchangeable hydrogen isotopic compositions (δ(2) H values) of bulk complex organic materials is difficult due to uncontrolled H isotope exchange between the organic material and ambient water vapor. A number of calibration keratinous materials with carefully measured hydrogen isotopic compositions of the non-exchangeable fraction were proposed to enable stable isotope laboratories to normalize their (2) H measurements. However, it was recently reported that high temperature carbon-reactor methods for measuring the hydrogen isotopic composition of nitrogenous organic materials is biased by the production of HCN in the reactor...

Papillary lesions of the breast pose great diagnostic challenges on fine needle aspiration cytology (FNAC) due to overlapping features between benign and malignant entities. Preoperative cytodiagnosis is difficult. We present a case of a 52-year-old male who presented with a progressively increasing firm swelling in the left breast for 3 years. The nipple was eroded with ulceration and bleeding. Ultrasonography (USG) revealed a mass measuring 2.9 cm × 1.5 cm in the left breast. FNAC smears were hypercellular with ductal cells arranged in papillae and glandular clusters...

Much of the precipitation delivered to western North America arrives during the cool season via midlatitude Pacific storm tracks, which may experience future shifts in response to climate change. Here, we assess the sensitivity of the hydroclimate and ecosystems of western North America to the latitudinal position of cool-season Pacific storm tracks. We calculated correlations between storm track variability and three hydroclimatic variables: gridded cool-season standardized precipitation-evapotranspiration index, April snow water equivalent, and water year streamflow from a network of USGS stream gauges...
