Comparison of Low-Dose Non-contrast CT in Detecting Anatomical and Surgically Important Variants of Paranasal Sinuses to Standard Dose Non-contrast CT: Experience from a Tertiary Care Hospital in Sub-Himalayan Region of Northern India.

Computed tomography (CT) is the gold standard for diagnosing sinusitis and anatomical variations and a guide for paranasal sinus (PNS) surgeries. High doses of radiation lead to increased risk of head and neck malignancies, radiation-induced cataracts, hypothyroidism, and hyperthyroidism. The purpose of this study was to assess the effectiveness of low-dose CT as compared to standard-dose CT in the identification of anatomical variants of paranasal sinus and rhinosinusitis.

Iodine-125 brachytherapy for choroidal melanoma by using Ocuprosta seeds with indigenous non-collimated plaques: Our initial experience.

Purpose: Brachytherapy is the gold-standard treatment for choroidal melanoma. This study evaluated iodine-125 brachytherapy by using Ocuprosta seeds with indigenous non-collimated plaques in Asian patients.

Methods: Retrospective single-center study in a tertiary care hospital of 12 eyes with choroidal melanoma in 12 Asian patients who underwent brachytherapy with Ocuprosta seeds fixed on non-collimated plaques and had a follow-up of at least 32 months (mean: 42.

Neurological manifestations of scrub typhus: encephalitis and Guillain-Barré syndrome (GBS).

Scrub typhus is a tropical febrile illness that mainly affects rural populations in tropical and subtropical countries. It can range in severity from a mild febrile illness to multisystem involvement. Systemic dysfunction often appears in the second week of sickness, and hepatic, renal and brain involvement are well documented.

Synovial Sarcoma of Ethmoidal Sinus.

 Synovial sarcoma is an aggressive soft tissue cancer of extremities mainly and rare in head and neck region, whereas rarest in ethmoidal sinus as only three cases have been reported till date.  We managed two cases of synovial sarcoma who presented with nasal obstruction, epistaxis, and swelling around the nasofacial region. Endoscopic nasal biopsy and immunohistochemistry markers confirmed synovial sarcoma in both the cases.

Comparison of Contrast Enhanced Ultrasound With Contrast Enhanced Computed Tomography for the Diagnosis of Hepatocellular Carcinoma.

Background/aims: The most common primary malignant tumor of liver is hepatocellular carcinoma (HCC). The highest risk of developing HCC is seen in patients of cirrhosis. Ultrasound is used for surveillance in these patients.
