Clinicopathologic features and outcomes of primary vaginal adenosis as a dermatologic and gynecologic burden: A retrospective study.

In the recent 20 years, primary vaginal adenosis is extremely rare and the data of clinical presentations, management, and outcome have not been studied systematically.In this retrospective study, women with vaginal adenosis between January 1997 and June 2017 were identified from the hospital's medical records. Data on patient age, history, symptoms, mass location, size, diagnosis, complications, treatment, and recurrence were analyzed by SPSS 20.0.Twenty women were histopathologically diagnosed as having vaginal adenosis (mean age, 37.9 ±â€Š10.6 years). All patients denied utero exposure. The most common symptom was vaginal pain or abnormal bleeding. For all patients, the local vaginal lesions were surgically excised. Seven patients had complications with endometriosis. 15 patients lived without recurrence, and 1 patient underwent postoperative local recurrence after 81 months. Primary vaginal squamous cell carcinoma in another patient was confirmed to arise from adenosis; she survived with disease. The remaining 3 patients developed carcinoma of different types in varied periods of a disease-free state (5 months, 30 months, and 23 years, respectively); 1 patient died of progressive disease, and 2 patients survived with disease.Primary vaginal adenosis is a spontaneous lesion with a propensity for late canceration. Local lesion resection is the primary treatment.

Protective effect of a natural carrageenan on genital herpes simplex virus infection in mice.

In the present study, the protective effect of 1T1, a lambda-carrageenan extracted from the red seaweed Gigartina skottsbergii was evaluated in a murine model of herpes simplex virus type 2 (HSV-2) genital infection. Six to eight-week-old female BALB/c mice were intravaginally inoculated with a lethal dose of HSV-2 (MS strain) and pre- or post-infection treated with different doses of a 10mg/ml solution of 1T1. A single topical administration of 1T1 shortly before infection of BALB/c mice with HSV-2 protected 9 out of 10 mice from HSV-2-induced lesions and mortality, compared with only 10% survival in control mice. In addition, 1T1 produced a total blockade in virus shedding in the vaginal secretions. When 1T1 pre-treatment was reinforced with a second dose 2h after infection, total protection was observed even when the prophylactic administration had taken place at 60min before infection. The irreversible virucidal action of 1T1 against herpes virus seems to be responsible of its protective effect against virus replication and mortality following vaginal HSV-2 infection.

Progression of intravaginal infection by herpes simplex-2 in genetically athymic mice.

The purpose of this paper was to study the pathogenesis of wild-type Herpes simplex-2 (HSV-2) primary intravaginal (IVAG) infection in genetically athymic (nude) mice. Nude (nu/nu) N: NIH(S) and Balb/c mice, as well as their euthymic counterparts were IVAG infected with 5 x 10(5) pfu of HSV-2. The progression of the infection was followed by HSV-2 immunolabeling using the peroxidase-antiperoxidase technique in tissue sections of the whole body, electron microscopy, and viremia titration at two different time points. 70% of athymic NIH mice, 30% of euthymic NIH mice, and 80% of both athymic and euthymic Balb/c mice developed acute vulvovaginitis and died between 8-10 days post-infection (pi). Viremia was not detected in either athymic or euthymic mice. HSV-2 replicated in the vulvovaginal, vesical and perianal epithelia, then progressed towards the central nervous system mainly along autonomic nerves and ganglia. HSV-2 antigens were not detected in liver, spleen, kidney, skin, heart, lung or bone marrow. The conclusion is that the T-cell immune response seems to limit the IVAG infection of NIH mice at the inoculation site, but is not involved in preventing HSV-2 dissemination through the blood.

Hydrocolpos.

The method of presentation and problems in diagnosis of 3 cases of hydrocolpos are discussed. The anatomy and embryology of the abnormality is described. The methods of treatment and results are outlined.

Long-term follow-up after conservative surgery for rectovaginal endometriosis.

OBJECTIVE: The purpose of this study was to evaluate long-term results in patients who received conservative surgical treatment for rectovaginal endometriosis. STUDY DESIGN: We analyzed the follow-up data for 83 women who underwent surgery for rectovaginal endometriosis. The inclusion criteria were age 20 to 42 years, moderate-to-severe pain symptoms, conservative treatment with retention of the uterus, and at least 1 ovary; the follow-up period was > or =12 months. Kaplan-Meier analysis and Cox regression were used to calculate recurrence rates. RESULTS: The cumulative rates of pain recurrence, clinical or sonographic recurrence, and new treatment were 28%, 34%, and 27%, respectively. The younger patients had the higher risk of recurrence. Pregnancy had protective effects against the recurrence of symptoms and a need for a new treatment. Patients who underwent bowel resection had fewer recurrences. CONCLUSION: Segmental resection and anastomosis of the bowel, when necessary, improves the outcome without affecting chances of conception. Higher recurrence rates in younger patients seems to justify a more radical treatment in this group of women.
