Observational Study
Association between polycystic ovarian syndrome and endometrial, ovarian, and breast cancer: A population-based cohort study in Taiwan.
Polycystic ovary syndrome (PCOS) is a common endocrine disorder among the women of reproductive age. We conducted a nationwide population-based retrospective cohort study to analyze the association between PCOS and the subsequent development of gynecological cancers, namely endometrial, breast, and ovarian cancer. For this population-based cohort study, we used the Taiwan National Health Insurance Research Database, which contains information on approximately 24.7 million insured individuals. ⋯ A statistically significant higher risk of endometrial cancer was found in the PCOS cohort (adjusted HR [aHR] = 17.7, 95% CI = 4.9-64.2) than in the comparison cohort. However, no association was observed between PCOS and ovarian (aHR = 1.64, 95% CI: 0.63-4.27) or breast cancer (aHR = 0.98, 95% CI: 0.58-1.65). The results of this large population-based cohort study supported the premise that women with PCOS might have an increased risk of endometrial cancer, but no association between PCOS and the risks of ovarian and breast cancer was found.

Observational Study
Prognostic factors to survival of patients with chondroblastic osteosarcoma.
This study was aimed to reveal the changes in survival rates and prognostic factors to survival of chondroblastic osteosarcoma (COS). Patients from the Surveillance, Epidemiology, and End Results (SEER) database were retrieved. Kaplan-Meier survival analysis and Cox proportional hazard model were used during analysis. ⋯ Younger onset age, patients of white race, well and moderately differentiated tumors, and surgery independently predicted better overall (Hazard ratio [HR]: 1.034, P < .001*; HR: 0.538, P = .004*; HR: 0.240, P = .020* and HR: 0.350, P < .001*, respectively) and cancer-specific (HR: 1.031, P = .002*; HR: 0.592, P = .036*; HR: 0.098, P = .027* and HR: 0.253, P < .001*, respectively) survival. Metastasis at diagnosis independently predicted worse overall (HR: 3.108, P < .001*) and cancer-specific (HR: 4.26, P < .001*) survival compared to no metastasis. Younger onset age, white race, well and moderately differentiated tumors, no metastasis at diagnosis and surgical resection can independently predict better overall and cancer-specific survival of COS.

In psychiatric disorders, interindividual differences in cytochrome P450 (CYP)2D6 (CYP2D6) enzymatic activity could be responsible of adverse drug reactions (ADRs) and therapeutic failures (TFs) for CYP2D6-metabolized drugs, contributing to the periodical hospital readmissions of the revolving door (RD) condition. ⋯ Our findings may suggest that CYP2D6 clinically relevant genotypes may be involved in the unwanted outcomes observed in RD patients with BD.

Case Reports
Acute diffuse and transient thyroid swelling after intravenous thrombolysis for acute ischemic stroke: A case report.
Intravenous thrombolysis is the primary therapy for acute ischemic stroke (AIS), but it has some complications, including symptomatic intracranial hemorrhage, orolingual angioedema, and extracranial bleeding. However, thyroid disorders associated with thrombolysis are very rare. ⋯ After intravenous thrombolysis for AIS, several life-threatening complications, such as hemorrhage and orolingual angiedema, also can cause neck swelling. Urgent intubation and surgery may be required. However, the rare complication, acute diffuse thyroid swelling, is self-limiting and nonfatal and conservative treatment is sufficient. Neck ultrasound is helpful in rapidly distinguishing these complications.

As a very rare vascular tumor, breast angiosarcoma (AS) can be divided into primary and second breast AS. However, the latter is slightly more commonly detected in clinical practice. Radiation post mastectomy is the common cause for the secondary breast AS, and although there are other reasons, it is still quite rare. In the present study, we reported a rare case of breast AS and summarized the relevant literatures so that to conduce to diagnose AS. ⋯ Based on our findings, we concluded that repeated resection might be a risk factor for the breast AS, especially for a gradual pathological evolution from benign to malignant. This case showed a very rare cause for angiomatosis of breast, and the patient had a successful outcome after a simple mastectomy.
