Severe radiation thyroiditis after radioactive iodine for treatment of Graves' disease

Radiation thyroiditis resulting from radioactive iodine-131 treatment for Graves' disease is an uncommon complication. Although a majority of patients are asymptomatic or manifest mild symptoms that can be managed conservatively, published literature describing severe radiation thyroiditis resulting in significant morbidity is lacking. We herein report on six patients with severe radiation thyroiditis that resulted in hospitalisation, including an unusual complication of myopericarditis.

Current Status and Growth of Nuclear Theranostics in Singapore / 대한핵의학회잡지

The concept of theranostics, where individual patient-level biological information is used to choose the optimal therapy for that individual, has become more popular in the modern era of ‘personalised’ medicine. With the growth of theranostics, nuclear medicine as a specialty is uniquely poised to grow along with the ever-increasing number of concepts combining imaging and therapy. This special report summarises the status and growth of Theranostic Nuclear Medicine in Singapore.We will cover our experience with the use of radioiodine, radioiodinated metaiodobenzylguanidine, peptide receptor radionuclide therapy, prostate specific membrane antigen radioligand therapy, radium-223 and yttrium-90 selective internal radiation therapy.We also include a section on our radiopharmacy laboratory, crucial to our implementation of theranostic principles. Radionuclide theranostics has seen tremendous growth and we hope to be able to grow alongside to continue to serve the patients in Singapore and in the region.

Advantage investigation of totally laparoscopic modified Roux-en-Y reconstruction / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical advantage of the application of modified Roux-en-Y reconstruction after totally laparoscopic total gastrectomy.</p><p><b>METHODS</b>Clinical data of 36 patients who underwent totally laparoscopic total gastrectomy with Roux-en-Y reconstruction by one medical team for gastric adenocarcinoma between January 2014 and December 2014 in the Second Hospital of Jilin University were retrospectively analyzed. Patients were divided into classic Roux-en-Y group (CRY, 16 cases) and modified Roux-en-Y group (MRY, 20 cases) according to reconstructive methods. The data concerning the intraoperative and postoperative situation in two groups were compared.</p><p><b>RESULTS</b>Operation was successfully completed in all the cases without conversion to laparotomy. Compared to CRY group, MRY group had shorter mean operative time [(260.9 ± 21.2) min vs. (287.9 ± 19.0) min, P=0.000], shorter mean reconstruction duration [(32.4 ± 9.2] min vs. (45.4 ± 13.2) min, P=0.001] and less intraoperative bleeding [(50.9 ± 23.5) ml vs. (67.0 ± 20.5) ml, P=0.000]. Jejunum mesentery dissection and jejunum resection were not necessary in MRY group. However, there were no significant differences in lymph nodes harvested, time to flatus, hospital stay and postoperative complications between two groups.</p><p><b>CONCLUSIONS</b>As compared to classic Roux-en-Y reconstruction, the modified Roux-en-Y reconstruction can simplify the surgical procedures and achieve similar efficacy. It is feasible and safe, and worth further promotion in clinical practice.</p>

Postmastectomy/Axillary Node Dissection Chyloma: The Additional Value of SPECT/CT Lymphoscintigraphy / 한국유방암학회지

After mastectomy and axillary node dissection, chylous leakage is rare. However, considerable anatomical variation in the termination of the thoracic duct has been reported. Hence, during breast surgery, injury to the lateral terminating branch is not unlikely and might lead to retrograde chyle leak. Herein, we describe a patient who had a chylous leakage at her wound site after a left simple mastectomy and axillary node dissection and for whom lymphoscintigraphy with Tc-99m albumin nanocolloid was performed. In this case, additional hybrid single-photon emission computed tomography/computed tomography study was done, and has helped with the accurate identification of the chyle leakage site, thus aiding in surgical management.

Prick negative electrostatic field(PNESF)and the life spans of mice with ascites tumors / 中华物理医学与康复杂志

Objective To study the effects of PNESF at different voltages on the life spans of ascites tumor bearing mice.Methods Forty ascites tumor bearing mice were divided into 5 groups and exposed to PNESF at 0,10,17,23 and 30 kV,respectively,for 30 minutes daily on 4 successive days.All of the animals then received routine care until death.Their eating habits,body weights and life spans were observed.A straight line fitting method was used for statistical analysis. Results The body weights of the mice exposed to 17 kV and 23 kV PNESF increased quickly during the four days of PNESF exposure.The weight gain in all groups declined after PNESF exposure was stopped.Thereafter the body weights of the mice exposed to the 17 kV PNESF increased more slowly than those in the control group.The mice exposed to the 23 kV PNESF gained weight more quickly than other groups.The mice exposed to the 17 kV PNESF lived the longest,demonstrating a lengthening of life of 25.5%compared with the control group.Conclusion Exposure to a PNESF of appropriate intensity might significantly increase the life span of ascites tumor bearing mice.

Long-term prognostic analysis of thymectomized patients with myasthenia gravis / 中华医学杂志(英文版)

<p><b>OBJECTIVE</b>To study the factors affecting the long-term prognosis of patients with myasthenia gravis (MG) after thymectomy.</p><p><b>METHODS</b>170 MG patients who had undergone thymectomies were studied retrospectively. Among them, 124 patients received long-term follow-up for more than 40 months postoperatively. The COX regression analysis model was used to analyze the factors that may influence the long-term prognosis. These factors included thymus pathology, patient gender, age, duration of disease at the time of surgery, preoperative Osserman classification and medication.</p><p><b>RESULTS</b>The research showed that thymus pathology was the single independent factor that affected the postoperative long-term prognosis. The long-term survival rates differed significantly with thymus pathological types: hyperplasia > benign thymoma > atrophy > malignant thymoma (P < 0.05).</p><p><b>CONCLUSION</b>The different pathological types of the thymus were the important factor affecting long-term survival in MG patients after thymectomy.</p>
