Gestational Gigantomastia: A Case Report.

Gestational gigantomastia is a rare disorder characterized by rapidly progressive hypertrophy of the breast tissue during pregnancy. Its prevalence is approximately 1:100,000, and although the etiology of this condition remains unclear, it may be related to hormonal change. This study reports the case of a 39-year-old pregnant woman at 22 weeks of gestation with massive enlargement of bilateral breasts (gigantomastia) and presents the sonographic findings of this rare condition which shows different parenchymal patterns from those of normal breasts and is uncommonly seen.

Success Rates and their Related Factors in Patients Receiving Radioiodine (I-131) Treatment for Hyperthyroidism.

Background And Objective: The success rate of I-131 therapy for hyperthyroidism is dependent on several factors. The aim of the present study was to evaluate the success rates, and the factors which affected them, in patients with hyperthyroidism at Rajavithi Hospital who received I-131 therapy with doses based on thyroid gland weight (gram), clinical findings, and 3-hour radioiodine uptake (3-hr RAIU).

Material And Method: A retrospective study was performed of 305 hyperthyroid patients who received initial I-131 therapy at the Nuclear Medicine Department of Rajavithi Hospital, Bangkok between January 2010 and December 2014.

Radioiodine (1-131) Dose for the Treatment of Hyperthyroidism in Rajavithi Hospital.

Background: The main cause of hyperthyroidism is diffuse toxic goiter (Graves' disease), and the treatment of choice after medical therapy failure is radioiodine (I-131). There are two common methods of determining the optimal I-131 dose: calculated dose or fixed dose. The calculated dose method is based on the following formula: 75-200 microcuri/gram of thyroid gland divided by the percentage of radioiodine uptake at 24 hours (24-hour RAIU).

Normal Solid Gastric Emptying Values Measured by Scintigraphy Using Asian-style Meal:A Multicenter Study in Healthy Volunteers.

Background/aims: To report gastric emptying scintigraphy, normal values should be established for a specific protocol. The aim of this study was to provide normal gastric emptying values and determine factors affecting gastric emptying using Asian rice-based meal in healthy volunteers.

Methods: One hundred and ninety-two healthy volunteers were included at 7 tertiary care centers across Thailand.
