Internal Jugular Vein Thrombosis After Microwave Ablation of Cervical Lymph Node Metastasis in Papillary Thyroid Microcarcinoma: A Case Report.

In this study, two patients with papillary thyroid carcinoma and lymph node metastasis were treated by Dr. Shurong Wang's team and are reported. The two patients refused surgery and underwent microwave ablation (MWA) of the thyroid and lymph node lesions. Ultrasound review 2 days after MWA revealed internal jugular vein thrombosis. Patient #1 received low molecular weight heparin calcium injection, Xueshuantong injection, Xiangdan injection, and rivaroxaban. Patient #2 was treated with enoxaparin sodium injection, Xueshuantong injection, urokinase, and warfarin sodium tablet. The thrombus was successfully managed in each patient using anticoagulant treatment. Such complication of MWA has not been reported in many cases before. According to the relevant literature, thrombosis after thyroid cancer ablation might be related to subclinical hypothyroidism, increased heme oxidase 1 (HO-1) levels in the blood of patients with papillary thyroid cancer, and increased platelet content and mean platelet volume in patients with thyroid cancer. No specific cause of thrombosis was identified in the two cases reported here. No recurrence was observed after 1 (patient #1) and 4 (#2) years of follow-up. In conclusion, patients with papillary thyroid carcinoma and lymph node metastasis should undergo color Doppler ultrasound of the neck after MWA of thyroid lesions and neck metastasis.

Telbivudine can safely reduce mother-to-child transmission in chronic hepatitis B women after 12 weeks of gestation.

BACKGROUND: To evaluate the efficacy and safety of telbivudine in chronic hepatitis B women during the second and third trimesters of pregnancy. METHODS: The week 12-34 of pregnant women were screened in this prospective non-intervention study, with HBV DNA > 106 IU/mL and alanine aminotransferase > 50 IU/L. The patients were received telbivudine treatment as a treatment group or without antiviral treatment as a control group. All infants were received recombinant hepatitis B vaccine 10 µg within 12 h of birth, at week 4 and week 24, immunoglobulin G within 12 h of birth and were detected HBV markers at the range from 7 to 12 months after delivery. RESULTS: A total of 241 patients were finally enrolled, 139 patients in telbivudine group and 102 patients in control group. HBsAg negative rate of infants was 99.3% (135/136) in telbivudine group and was 91.9% (91/99) in control group after 7 months (P = 0.005), respectively. The incidence of undetectable HBV DNA levels (47.5%) was significantly lower in telbivudine-treated mothers than that in the controls (0%), and 75.5% patients alanine aminotransferase returned to normal in telbivudine group, and 51% in control group at delivery (P < 0.001), respectively. CONCLUSIONS: Telbivudine can safely reduce mother-to-child transmission in chronic hepatitis B women after 12 weeks of gestation.

Prevalence of colorectal neoplasm in Chinese patients with high-risk coronary artery disease classified by the Asia-Pacific Colorectal Screening score.

OBJECTIVE: The aim of this study was to investigate the prevalence of colorectal neoplasms in patients coronary artery disease (CAD) with or without a family history of colorectal cancer (CRC). METHODS: In this cross-sectional study, individuals with suspected CAD in the absence of cancer-related symptoms underwent coronary angiography for the first time, and were divided into CAD and non-CAD groups. Colonoscopy was performed in individuals at high-risk tier based on their Asia-Pacific colorectal screening (APCS) score. Their waist circumference (WC), height and body weight were measured. RESULTS: There were 634 of 1157 individuals at a high risk of developing advanced colorectal neoplasms, 91.0% (577/634) of whom were male smokers. The proportion of CAD patients in the high-risk tier was 81.5% (517/634), while the prevalences of adenomas (32.1% vs 22.2%, P < 0.05) and advanced adenomas (14.7% vs 8.5%, P < 0.05) were significantly higher in the CAD group than in the non-CAD group. After 83 individuals with a family history of CRC were excluded, only the prevalence of adenomas was still significantly higher in the CAD group than in the non-CAD group (25.5% vs 16.0%, P < 0.01). Body mass index (BMI) ≥ 25 kg/m(2) was correlated with the occurrence of adenomas (OR 2.133, 95% CI 1.219-3.730, P = 0.008) in CAD patients. CONCLUSIONS: Even in the absence of family history of CRC, CAD patients at a high risk of developing advanced colorectal neoplasms classified by the APCS score still showed a remarkably high prevalence of colorectal adenomas. Moreover, the association between the occurrence of adenomas and CAD was stronger in overweight (BMI ≥ 25 kg/m(2)) individuals.
