The purpose of this study is to investigate the prevalence and the morphologic characteristics of the radicular groove and root canal system in human mandibular second premolars with C-shaped root in a Taiwan Chinese subpopulation using cone-beam computed tomographic (CBCT) imaging. ⋯ There was a 2-3% morphologic variation of the mandibular second premolar with a C-shaped root canal system among the Taiwan Chinese subpopulation investigated in this study. Detailed knowledge of the morphological characteristics of teeth may be valuable when choosing clinical treatments.

Review Case Reports
Extramedullary hematopoiesis involving the thyroid: A rare cytologic finding in otherwise healthy patients and review of literature.
The thyroid gland is an uncommon site for the presence of extramedullary hematopoiesis (EMH). We report the cases of four Taiwanese women with hematopoietic elements on the smears of thyroid fine needle aspiration (FNA) samples and compare the findings with those of previously reported cases. ⋯ Four patients were noted to have bone marrow elements on the smears among 63,361 thyroid FNA samples. These four Taiwanese women presented with nodular goiter and foci of hematopoietic elements by thyroid FNA without any chronic disease of hematopoietic tissue or any evidence of a thyroid malignancy.

Case Reports
Clinical management of gamma-hydroxybutyrate (GHB) withdrawal delirium with CIWA-Ar protocol.
Gamma-hydroxybutyrate (GHB) is a synthetic drug used mainly for recreational purpose. Although the prevalence of GHB abuse is low in Taiwan, GHB has become increasingly popular in certain subpopulations such as clubbers and men who have sex with men (MSM). GHB dependence could be associated with severe withdrawal syndrome including hallucinations and delirium. ⋯ Here we present a case of GHB withdrawal delirium that was treated successfully with fixed and symptom-triggered benzodiazepine dosing regimen based on Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) scale. The utilization of CIWA-Ar in such cases could offer useful guidance for benzodiazepine dosing. To the best of our knowledge, this is the first case report of GHB withdrawal delirium in Taiwan.

Cancer risks of residents living north to the No. 6 Naphtha Cracking Complex has not been studied before. ⋯ We conclude that all-cause cancer risk was significantly increased for Taisi residents living near the No. 6 Naphtha Cracking Complex for 10-16 years after the complex began operating.

Although antiviral therapy reduces development of hepatocellular carcinoma (HCC) in patients with chronic hepatitis C (CHC), HCC often develops in patients with non-sustained virologic response (non-SVR). We aimed to evaluate risk factors for HCC in HCV patients with non-SVR. ⋯ Liver cirrhosis, high APRI levels, and IL28B rs12979860 at baseline are independent risk factors for HCC development in patients without SVR after peg-IFN combination therapy.
