Malignant tumor is the greatest risk factor for pulmonary embolism in hospitalized patients: a single-center study.

Background: This study aimed to investigate the background of patients who presented with pulmonary embolism (PE) on contrast-enhanced chest computed tomography (CT) and to explore the risk factors for PE.

Methods: This study included a review of the medical records of all 50,621 patients who were admitted to one community hospital between January 1, 2013 and December 31, 2017. Data on sex, age, risk factors related to blood flow stagnation (obesity, long-term bed rest, cardiopulmonary disease, cast fixation, long-term sitting), risk factors related to vascular endothelial disorder (surgery, trauma/fracture, central venous catheterization, catheter tests/treatments, vasculitis, antiphospholipid antibody syndrome, history of venous thromboembolism (VTE)), and risk factors related to hypercoagulability (malignant tumor, use of oral contraceptives/low-dose estrogen progestin/steroids, infection, inflammatory enteric disease, polycythemia, protein C or protein S deficiency, dehydration) were evaluated.

HPV genotyping for triage of women with abnormal cervical cancer screening results: a multicenter prospective study.

Background: In cervical cancer screening programs, women with abnormal cytology are referred for colposcopy for histological evaluation. We examined whether a human papillomavirus (HPV) genotyping assay could be used to identify women who do not need immediate colposcopy and biopsy because of low risk of cervical intraepithelial neoplasia grade 3 or worse (CIN3+).

Methods: We prospectively evaluated test performance for 2 carcinogenic HPV genotypes (HPV16/18), for 8 types (HPV16/18/31/33/35/45/52/58), and for 13 types (HPV16/18/31/33/35/45/51/52/56/58/59/68) for prediction of histological CIN3+ results among 427 screen-positive women referred for colposcopy.

Optimizing biopsy procedures during colposcopy for women with abnormal cervical cancer screening results: a multicenter prospective study.

Background: In cervical cancer screening programs, women with abnormal cytology results are referred to colposcopy for histological diagnosis. This study was designed to evaluate the sensitivity of colposcopic procedures for detecting cervical cancer and its precursor, cervical intraepithelial neoplasia (CIN).

Methods: Women referred to colposcopy for abnormal cytology were enrolled from four hospitals.

Ovarian tumor with functioning stroma.

The authors reported two cases with ovarian tumors with functioning stroma. One was an ovarian carcinoid with testosterone-producing stroma and another was an ovarian mucinous cystadenoma with elevated serum level of estrogen. They appeared as multilocular cystic masses with varying signal on MR.
