Herpes simplex vegetans: atypical genital herpes infection with prominent plasma cell infiltration in B-cell chronic lymphocytic leukemia.

SUMMARY: Herpes simplex vegetans is a rare disorder even in immunocompromised patients. It typically affects patients with HIV or myeloproliferative diseases.The atypical cutaneous lesions show papillomatous vegetations in varying locations. Histologically the lesions show pseudoepitheliomatous hyperplasia of squamous epithelium, plasma cell infiltration and are positive for HSV 1 and/or HSV 2. Herpes simplex vegetans often responds poorly to treatment in immunocom-promised patients.

Evaluation of quantitative ultrasound tissue characterization of the cervix and cervical length in the prediction of premature delivery for patients with spontaneous preterm labor.

OBJECTIVE: This study was to evaluate the predictive value of the uterine cervix tissue with the use of quantitative ultrasound gray level analysis for preterm delivery. STUDY DESIGN: Sixty-eight patients with preterm labor between 20 and 35 weeks of gestation were included. When two-dimensional transvaginal ultrasound measurement of cervical length was completed, a region of interest of constant size was defined in the midsection of the posterior wall, and the tissue-specific gray scale was determined. Preterm delivery of <37 weeks of gestation was sought. RESULTS: Twenty-eight patients (41.2%) were delivered preterm. The risk for preterm delivery was increased significantly in patients with cervical length of /=4 (odds ratio, 3.44; 95% CI, 1.21-9.75), and with decreased mean gray scale value (odds ratio, 12.13; 95% CI, 3.69-39.88). Parity and uterine contractions were not significant as predictors for preterm delivery, although the risk for preterm delivery increased with higher parity (odds ratio, 1.8; 95% CI, 0.68-4.79). The risk for preterm delivery remained nearly the same by uterine contractions (odds ratio, 0.92; 95% CI, 0.28-3.01). A mean scale value of
