Treatment of vaginal intraepithelial neoplasia (VAIN) with the carbon dioxide laser.

The increasing incidence of VAIN especially in young women, the frequent relapses, and renewed interest in maintaining sexual function have prompted gynecologists to a conservative management of the disease. Over the last decades, surgery, 5-fluorouracil, chemosurgery, electrocautery and cryotherapy were used. Carbon dioxide laser ablation therapy of VAIN has been reported from various authors with different results. From June 1991 through December 1998, 39 patients affected by VAIN were treated with laser surgery (35 vaporizations and 4 excisions). To achieve complete elimination of all lesions, seven patients had two vaporizations and one patient three. One patient was submitted to six combined repeated treatments. Five patients were not evaluable and three presented persistence of VAIN. One patient died because of AIDS. The remaining 30 patients, treated with laser surgery, were lesion free: 7 patients were negative at 12-24 months, 10 at 24-36 months and 13 at 37-90 months. No important complications occurred. Sexual function was not compromised. Carbon dioxide laser is a safe and efficacious tool in the treatment of pre-neoplastic lesions of the vagina.

[Pregnancy cholestasis. Clinical aspects and neonatal outcome].

AIM: Gravidic cholestasis is a syndrome that is usually manifested during the third trimester of pregnancy and regresses in puerperium. It is characterized by the onset of itch, with or without associated jaundice and alterations of hepatic functional parameters. Its incidence varies according to geographical area. METHODS: A retrospective analysis was made regarding the frequency of this pathology in pregnant patients attending the Gynecology and Obstetrics Clinic of Trieste from 1-1-1980 to 31-7-1997. The epidemiological and clinical characteristics were studied relating to the course of pregnancy and neonatal outcome. Patients were identified on the basis of diagnosis on admittance and anamnestic and laboratory data, generalised itch and increased transaminase, biliary salts and alkaline phosphatase. Patients suffering form active-phase viral hepatitis were excluded, as were those in whom symptoms appeared after the start of alpha methyldopa administration. RESULTS: The frequency of gravidic cholestasis in this series was 0.36%. No significant differences were recorded in terms of age, parity and weight increase in these patients compared to the general population of pregnant women. Birth was spontaneous in 66% and by cesarean section in 34%. The frequency of premature births was 12%. The Apgar score at 5 min was satisfactory in all neonates. CONCLUSIONS: Careful monitoring of pregnancy associated with suitable obstetric care enabled a zero rate neonatal and maternal mortality to be achieved.

[Laser surgery in the conservative management of vaginal intraepithelial neoplasms].

BACKGROUND AND AIMS: The increase finding of vaginal intraepithelial neoplasia (VaIN) in young women has led to the need to develop personalized conservative treatment. The authors studied the use of CO2 laser in the treatment of VaIN, evaluating the efficacy, repeatability, complications and the conservation of sexual function. METHODS: A total of 37 consecutive patients with histologically demonstrated VaIN (10 VaIN 1, 14 VaIN 2 and 13 VaIN 3): mean age 45.3 years, 37.8% aged < 35 years, 20/37 in childbearing age; VaIN was isolated in two patients, synchronous in 22 and in 13 cases it was metachronous with other intraepithelial or invasive genital neoplasia. 30/37 patients were treated with laser surgery as outpatients for a total of 41 operations (37 vaporisations and four excisions) using colposcopic guided CO2 laser with a constant emission power of 35 watts or 30 watts in the pulsed mode, under local anaesthesia, following the application of 5% acetic acid. RESULTS: Twenty-one (87.5%) of the 24 patients evaluated at 12 months were negative after one (16 patients) or more treatments (from 2 to 5 in 5 patients). Following the second recidivation, one elderly patient preferred traditional demolitive surgery; 2 patients are still awaiting further laser surgery. Five patients with multifocal lesions associated topical treatment with 5-fluorouracil. None of the sexually active patients complained of dyspareunias after treatment. CONCLUSIONS: Given the lack of other equally effective treatment and with the aim of preserving genital integrity, the authors regard laser surgery as the elective treatment for VaIN 2 and 3.

Squamous intraepithelial cervical lesions in human immunodeficiency virus-seropositive women.

OBJECTIVE: To evaluate the relationship between human immunodeficiency virus (HIV) infection, CD4 serum level, cervical squamous intraepithelial lesions (SILs) and risk factors for human papillomavirus (HPV)-related dysplasia in HIV-positive women. STUDY DESIGN: All 51 eligible patients who were seen at the Colposcopic Outpatient Service, Aviano Cancer Center, Aviano, Italy, from July 1, 1993, to June 30, 1994, were studied for risk factors for HPV and HIV infection and had cervical cytologic smears, colposcopy with cervical biopsy and a serum CD4 count. RESULTS: Thirty of 51 patients (59%) had cytohistologically confirmed SIL. The prevalence of SIL was higher in HIV Centers for Disease Control stage IV disease than stages II and III (22/29 vs. 8/22 P < .05). There was no significant difference in the CD4 count between women with or without SIL (321 +/- 310 vs. 401 +/- 295/mm3 [mean +/- SD]). No relationship was found between CD4 count and severity of SIL (low grade SIL, 210 +/- 203/mm3; high grade SIL, 580 +/- 357/mm3). CONCLUSION: In our series there was no relationship between CD4 count and cervical SIL, suggesting that the expression of HPV-related dysplasia is a complex process in which risk factors for genital SIL play an important role, while the role of HIV must be defined again.

[Laser conization guided by endocervical staining with methylene blue].

The authors report their experience of the use of a vital stain--methylene blue--as a surgical guide in laser cervical conization for CIN2-CIN3/CIS. During the period 1 October 1991-31 December 1992 a total of 40 laser cervical conizations were performed under local anesthesia using a CO2 laser connected to a microhandpiece and colposcope in patients with exo-endocervical lesions which were histologically positive for CIN2-CIN3/CIS. In 33/40 patients an aqueous solution of 1% methylene blue was introduced preoperatively in the endocervix using a cotton-wool bud with consequent impregnation of the pseudoglandular crypts: laser biopsy was performed along the guidelines of the stain itself. This enabled the direction of resection to be varied: in 3 patients due to an anomalous and eccentric direction of cervical canal; in 10 patients to remove glandular structures surrounding or underneath lesions; in 8 patients following pseudoglandular section to carry out deep vaporization (3 patients) or correct cutting edges (5 patients). The apex and edges of the cone were always intact. Fourteen patients completed a 12-month follow-up and a further 6 were followed up for 9 months; only 1/14 patients (with AIDS) showed recidivation after 1 year. In the authors' experience the use of a vital stain as a guide during laser cervical cone biopsy is an easily used method which ensures the greatest possible respect for healthy cervical structures, also in order to preserve fertility in young patients.

Papanicolau smear chances to be diagnostic for cervical squamous intraepithelial lesions (SIL) with or without detectable HPV DNA at in situ hybridization analysis.

The Authors have correlated 39 cervical diagnostic biopsies for squamous intraepithelial lesions (SILs) with correspective Papanicolau smears (PS), with relation to the presence or the absence of HPV of oncogenic type (HPV-one) detected by in situ hybridization (ISH). Agreement between cytological and histological diagnosis was present in 14 of 16 cases with detectable HPV-one and only in 12 of 23 cases without detectable HPV-one at ISH. The importance of the HPV type in the SILs with relation to the diagnostic accuracy of Papanicolaou smears has been discussed.

[Second surgery in the management of ovarian cancer].

The aim of this study was to evaluate the value of second surgery in the combined and multidisciplinary treatment of mullerian ovarian cancer. A retrospective study was carried out in 86 consecutive patients with advances stages of mullerian ovarian cancer (stage 3-4) referred to the Division of Gynecological Surgical Oncology of the Oncological Reference Centre at Aviano for continuation of treatment following initial surgery and chemotherapy performed in various peripheral institutions. Second surgery only revealed 11.6% of complete endocelomatic pathological responses (10 patients) to earlier treatments; among the 76 patients with persistent disease it was possible to achieve optimal redebulking in 50 (65.8%) (31 R0 and 19 R1 after second surgery), whereas it was not possible to perform adequate second surgery in 26 (34.2%). The impact of second surgery on the probability of survival (mean survival rate) was highly significant in the 50 patients in whom it was possible to perform adequate second surgery compared to the non-operated group (14.34 months versus 6.10, chi square = 12.671, p = 0.0004). The authors underline both the prognostic value of lymph node status with increased mortality among patients with positive retro-peritoneal lymph nodes (LN+), and the value of retroperitoneal re-evaluation in predicting endo-peritoneal recidivation in patients with free abdomen who subsequently relapsed.

[Percutaneous endoscopic gastrostomy (PEG) in upper gastrointestinal tract occlusion in gynecologic oncology].

BACKGROUND AND AIMS: Intestinal obstruction is a frequent cause of death in patients suffering from gynecological cancer, who have undergone multiple treatment in the form of surgery and/or chemotherapy and/or radiotherapy. The usual form of rescue treatment consists in the use of a nasogastric tube to administer support and analgesic treatment. Surgical gastrostomy is not a viable proposition in these extremely weak patients with large masses compressing and displacing the stomach. Percutaneous endoscopic gastrostomy (PEG), a technique first introduced for nutritional purposes, can be beneficially used to achieve decompression in these patients. METHODS: PEG was performed in a total of 67 patients who had already undergone multiple treatment for abdominal-pelvic neoplasia with upper gastrointestinal obstruction, who could no longer be operated and who had a life expectancy of less than sixty days. In three cases positioning was not possible owing to the lack of transillumination of the gastric and abdominal wall. 54/64 patients had previously undergone at least two operations. RESULTS: Esophagogastric lesions were found in 29% of patients, some of which were attributed to the nasogastric tube. Symptomatic wellbeing was obtained in 76.5% a few days after PEG. PEG remained in situ from 4 to 472 days. Slight peristomal infection was observed in 9% of cases. In seven cases it was necessary to add octreotide owing to the reappearance of symptoms. CONCLUSIONS: PEG is relatively easy to use and allows obstructive symptoms to be resolved in the majority of patients. Special medical skills are not required and the patient may be easily managed at home together with support therapy and pain management. Once PEG has been performed, it is possible to take fluids and semi-liquid foods, offering the patient a chance to taste flavours which have often been forgotten. PEG enables neoadjuvant chemotherapy to be performed in patients with previously untreated intestinal obstruction.
