ABSTRACT

The purpose of this study is to evaluate the efficiency of CO2 laser colposcopic guided surgery performed in an outpatient see and treat setting in the management of VHSIL. Women with a suspected diagnosis of VHSIL and no vulvoscopic suspicion of vSCC were enrolled. An electronic register of CO2 laser treatment was created where description of performing parameters (excision or ablation) was specified and personal history was recorded. Statistical analysis was performed by Fisher's exact test. Relative risks (RR) of risk factor were calculated and expressed in odds. From September 2014 to September 2018, we enrolled a total of 63 patients who underwent CO2 laser procedure and had a minimum follow-up time of 2 years at Careggi University Hospital in Florence. Forty-eight (76.2%) patients underwent laser excision and 15 (23.8%) patients underwent ablative treatment without histological results. Undertreatment was performed in 3 cases (6.3%) with definitive histology of vSCC. Therapeutical appropriateness of CO2 laser excision was reached in 85.4% of the cases (41/48). No volunteer loss to follow-up was registered; thus, fidelity to treatment was assess at 100%. Recurrence rate within 2 years attested in 8/60 followed patients (13.3%). No personal factor was found to influence the VHSIL course. CO2 laser excision may represent an excellent therapeutic option to VHSIL because it provides adequate oncological purpose with good cosmetic and functional results and high patients' loyalty to treatment. An expert team could allow to undergo patients with VHSIL suspicion to unique diagnostic and therapeutic procedure with significant benefits.

ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the colposcopic patterns observed in women with a histopathological diagnosis of vaginal intraepithelial neoplasia, with a particular interest in analyzing the colposcopic characteristics of low-grade squamous intraepithelial lesions (LSIL). PATIENTS AND METHODS: Medical charts and colposcopy records of women diagnosed with vaginal intraepithelial neoplasia from January 1995 to December 2015, were analyzed in a multicenter retrospective case series. The abnormal colposcopic patterns observed in women with vaginal LSIL and vaginal high-grade SIL (HSIL) were compared. The vascular patterns and micropapillary pattern were considered separately. RESULTS: Regardless the histopathological grading, in women with vaginal SIL, the grade I abnormal colposcopic findings were more frequent than grade II abnormalities. However, a grade I colposcopy was more commonly observed in women with a biopsy diagnosis of LSIL rather than HSIL (p<0.0001). Similarly, the micropapillary pattern was more frequently observed in women with LSIL (p=0.004), while vascular patterns were observed more frequently in women diagnosed with vaginal HSIL (p<0.0001). In women with grade I colposcopy, the menopausal status and a previous hysterectomy appeared to be associated with the diagnosis of vaginal HSIL. CONCLUSIONS: Grade I abnormal colposcopic findings were more commonly observed in women with vaginal LSIL, as well as the micropapillary pattern. On the other hand, grade II abnormal colposcopy and the presence of vascular patterns were more frequently observed in women with vaginal HSIL.

ABSTRACT

OBJECTIVE: The aim of this study was to analyse the women with high grade vaginal intraepithelial neoplasia (HG-VaIN), in order to identify a subset of women at higher risk of progression to invasive vaginal cancer. MATERIALS AND METHODS: The medical records of all the women diagnosed with HG-VaIN, and subsequently treated, from January 1995 to December 2013 were analyzed in a multicentre retrospective case series. The rate of progression to invasive vaginal cancer and the potential risk factors were evaluated. RESULTS: 205 women with biopsy diagnosis of HG-VaIN were considered, with a mean follow up of 57 months (range 4-254 months). 12 cases of progression to vaginal squamocellular cancer were observed (5.8%), with a mean time interval from treatment to progression of 54.6 months (range 4-146 months). The rate of progression was significantly higher in women diagnosed with VaIN3 compared with VaIN2 (15.4% vs. 1.4%, p < 0.0001). Women with HG-VaIN and with previous hysterectomy showed a significantly higher rate of progression to invasive vaginal cancer compared to non-hysterectomised women (16.7% vs. 1.4%, p < 0.0001). A higher risk of progression for women with VaIN3 and for women with previous hysterectomy for cervical HPV-related disease was confirmed by multivariable logistic regression analysis. CONCLUSIONS: A higher rate of progression to vaginal cancer was reported in women diagnosed with VaIN3 on biopsy and in women with previous hysterectomy for HPV-related cervical disease. These patients should be considered at higher risk, thus a long lasting and accurate follow up is recommended.

ABSTRACT

PURPOSE OF INVESTIGATION: To estimate the persistence rate of high-risk HPV DNA (HR-HPV DNA) in a population treated totally by laser CO2 conization for high-grade cervical intraepithelial neoplasia (HG-CIN), and to examine if this persistence might be considered an independent risk factor for relapsing disease. METHODS: All women with a histological diagnosis of HG-CIN and planned for laser CO2 conization from January 2003 to December 2004 were prospectively submitted to a HR-HPV test prior to surgery and at three and six months of follow-up. Women providing written informed consent with 24 months of follow-up were enrolled in the study group. A positive HPV test, involvement of resection margins, age at first intercourse, smoking habits, parity and age at conization > 50 years old were considered as risk factors for relapsing HG-CIN during follow-up, and were univariately and multivariately analyzed to discover any independent influencing factors. RESULTS: Of HG-CIN 15.4% resulted not to be HPV related nor relapsing. The HPV clearance rate after treatment was 78.8%. Involvement of resection margins and HR-HPV DNA persistence post-treatment resulted as the only two statistically significant risk factors for HG-CIN recurrence (rate 3.8%). HR-HPV DNA persistence in follow-up resulted to be independent from other risk factors at multivariate analysis. CONCLUSIONS: Although able to reach a low recurrence rate of HG-CIN, laser CO2 conization does not remove HPV infection completely from the cervix with a case of persistence in every five treated patients. In our experience this persistence in itself represents an independent risk factor for developing relapsing disease and constitutes the basis to introduce HPV testing even in the follow-up of patients treated for HG-CIN by laser CO2 conization.

ABSTRACT

The purpose of this study is to evaluate the feasibility, safety, and potential therapeutic benefit of laser CO(2) conization of the cervix for in situ and minimally invasive carcinoma diagnosed during pregnancy. Twenty-six pregnant patients with biopsy-proven carcinoma in situ/cervical intraepithelial neoplasia III but colposcopically suspicious for invasion underwent laser CO(2) conization during the 18th week of gestation in an outpatient setting under local anesthesia. No major intraoperative or postoperative complications occurred, and cervical cerclage was not required in any case. Two cases (7.7%) of occult FIGO stage IA1 minimally invasive cervical cancers with free surgical margins were diagnosed. Both patients delivered vaginally at term and were free of disease at postpartum follow-up. Median length of gestation was 39.1 weeks with a median birth weight of 3450 g. All 1-min Apgar scores were 8 or greater. Twenty patients (76.9%) delivered vaginally, while six patients underwent cesarean section for indications not related to the prior conization. After a mean postpartum follow-up of 18 months (range 3-42), 92.3% of patients continued to have both cytologic and colposcopic evaluations negative for persistent or recurrent disease. Two cases of persistent intraepithelial disease were successfully managed by reconization. In summary, our data suggest that laser CO(2) conization performed within the 18th week of gestation is safe for both the patient and the fetus, provides reliable histologic diagnosis, and can be curative. Further studies are required to confirm the favorable risk-benefit ratio of laser CO(2) conization in the management of non-reassuring cervical lesions observed in the first half of pregnancy.

ABSTRACT

OBJECTIVES: This study aimed to evaluate the usefulness of a comprehensive drug screening method as a first line diagnostic tool on clinical decision making in patients attending an emergency department for suspected drug overdose in terms of agreement between physicians on patients' disposal. METHODS: Five emergency physicians retrospectively evaluated the records of 142 adult patients, admitted to the emergency department of a community hospital for suspected drug overdose. They were asked for an expert opinion on patients' disposal at the end of the observation period, based on paired records, with/without the results of a comprehensive drug screening. RESULTS: In the absence of the drug screening, a very poor agreement (kappa statistics) was observed between physicians. When the drug screening was available, the interobserver agreement for decision on patients' disposal increased to the fair to good range (global agreement: from 0.238 (0.019) to 0.461 (0.020) (mean(SE)); p<0.001). The agreement also increased when admission to an intensive care unit, to a general ward, and discharge from hospital were separately analysed. The availability of drug screening would have saved 21.7% of hospital admissions and 53.3% of high dependency and/or intensive care unit admissions. CONCLUSION: Comprehensive drug screening adds to decision making for patients attending an emergency department for suspected drug overdose, improving agreement among physicians on patients' disposal and potentially saving hospital resources.

ABSTRACT

OBJECTIVE: The purpose of this study was to examine clinical implications of type III female genital mutilation and to evaluate the use of carbon dioxide laser surgery to restore vulvar opening and to treat associated epithelial inclusion cysts. STUDY DESIGN: Twenty-five infibulated patients underwent carbon dioxide laser treatment. Seven of the women (28%) were pregnant, between 10 and 37 weeks of gestation. Vulvar examination revealed five cases of epidermal inclusion cysts. One pregnant patient, with a cyst that was 7 cm in diameter, was at 24 weeks of gestation. Deinfibulation was performed in an outpatient setting with local anesthesia. A colposcopy-guided laser beam was used to create an incision along the fusion midline of the labia majora. In case of vulvar epidermal inclusion cyst, the capsule was opened and emptied of sebaceous contents; the inner surface of the cyst was vaporized completely. RESULTS: The carbon dioxide laser procedure restored a complete vulvar opening in all 25 patients. The complete vaporization of cyst capsule was possible in all five cases. No case of intraoperative or postoperative complication occurred. The average duration of follow-up was 11 months. Four patients who underwent deinfibulation antenatally had labor with spontaneous vaginal delivery and no evidence of perineal trauma. CONCLUSION: On the basis of the advantages that were observed, deinfibulation treatment must be offered to all infibulated patients. The procedure is particularly appropriate during pregnancy to prevent childbirth complications. Laser carbon dioxide has been proved to be a suitable technique for the treatment of female genital mutilation when inclusion cysts are associated with it.

ABSTRACT

OBJECTIVE: To evaluate CO2 laser excision, vaporization and combined techniques for treatment of vulvar intraepithelial neoplasia (VIN). STUDY DESIGN: Thirty-nine cases of VIN 3, 15 cases of VIN 2 and 9 of VIN 1, for a total of 63 patients with histologically proven VIN, underwent laser excision or vaporization under colposcopic guidance, using local anesthesia, in an outpatient setting or after day-surgery admission. Clinical aspects, cervical intraepithelial neoplasia (CIN) and vaginal intraepithelial neoplasia (VaIN) association, types of CO2 laser treatment, follow-up, recurrences and second treatments were evaluated. RESULTS: Twenty-seven (41.3%) patients underwent laser vaporization, and 37 (58.7%) with VIN 3, underwent laser excision or the combined technique. Colposcopic and biopsy examinations of patients with VIN revealed three cases of CIN 3 and nine cases of VaIN 3; two patients had concomitant VIN 3, CIN 3 and VaIN 3. Local anesthesia, using 2% carbocaine, and outpatient or day-surgery treatments were possible in all cases. A small incidence of intraoperative complications (4.8%) and absence of postoperative complications were observed. A single session was curative in 76.9% of patients treated with laser vaporization and in 78.4% of those treated with laser excision. Eleven cases of recurrent VIN and two cases of invasive vulvar carcinoma were observed during follow-up. A second laser procedure was carred out in all cases of relapsed VIN, with an overall cure rate of 96.8% after two treatments. Radical vulvectomy associated with inguinal-femoral lymphadenectomy was performed in the two cases of invasive carcinoma. CONCLUSION: CO2 laser surgery permits treatment of VIN in an outpatient or day-surgery setting under local anesthesia with excellent cosmetic and functional results. The treatment can also be adjusted to the patient's specific needs, with the possibility of calibrating the depth of the vaporized and removed tissues. Excisional treatment is the preferred method because it permits histologic evaluation of the excised tissue and detection of possible occult early invasion.

ABSTRACT

Cervical localization of uterine fibroids is an uncommon event and vaginal surgery by cold knife is the current therapeutic approach. Two patients with cervical fibroids underwent laser CO2 excision under colposcopic guidance, using local anesthesia and in outpatient setting. The absence of intra- and post-surgical complications and the successful therapeutical results prove that laser CO2 surgery could be an alternative treatment in selected cases.

ABSTRACT

BACKGROUND: The purpose of this retrospective study is to evaluate the appropriate management of ASCUS and LSIL pap smears by correlating the histological findings obtained by punch biopsy or excised specimens. METHODS: The study group included 584 women with abnormal pap smear: 358 with ASCUS and 226 with LSIL cytological abnormalities. All patients underwent colposcopy and, if necessary, directed-punch biopsy. In case of biopsy-proven dysplasia a destructive or excisional treatment was performed, as indicated. RESULTS: The prevalence of HPV-CIN histological lesions in ASCUS patients was 36.3% and in LSIL patients was 67.7%. High grade CIN was observed in 15.7 and 20.8% respectively. In one ASCUS patients an invasive lesion was diagnosed on punch biopsy and two LSIL patients showed stromal invasion on the final histopathologic report on excised specimens. CONCLUSIONS: Patients with ASCUS or LSIL pap smear exhibit a wide spectrum of histological findings ranging from no pathologic abnormality to frequent high grade CIN and invasive carcinoma in rare cases. Because of the histological assessment by directed-punch biopsy and its therapeutical indications, colposcopic examination is recommended for all women with a cytologic diagnosis of ASCUS and LSIL.

ABSTRACT

UNLABELLED: An increasing incidence of cervical intraepithelial neoplasia (CIN) among young women has been noticed in recent years. For this reason pregnancy might represent a peculiar opportunity to undergo cytocolposcopic examination for those women who do not take part in a screening program for cervical carcinoma. Diagnosis of CIN during pregnancy poses the question of the management of this disease and particularly of whether it is better to treat the lesion or not during pregnancy. To contribute to the solution of this issue we initiated a study on the management of high-grade CIN in pregnancy. MATERIAL AND METHODS: Five hundred and seventy-one pregnant women underwent cytologic, colposcopic and, when necessary, histologic examination. Those in whom a CIN was discovered in the first four months of gestation underwent laser conization. When the diagnosis of CIN was made after the sixteenth week of gestation, cytocolposcopic monitoring was performed every eighth week during pregnancy and two months after childbirth. Laser conization was performed under colposcopic guidance in the outpatient setting in all cases. All treated patients were submitted to cytologic, colposcopic and, if necessary, histologic examination every third month in the first year after treatment, every sixth month in the second year and yearly from the third year onwards. RESULTS: In 14 (2.4%) of the 571 examined women a CIN III was discovered, 6 of which associated with a human papilloma virus (HPV) infection. Of these, 8 patients, whose diagnosis was made within the sixteenth week of pregnancy, underwent laser conization. In one case a minor hemorrhage occurred during treatment. Two patients reported minor bleeding up to ten days after treatment. No major hemorrhages or cervical stenosis were observed. Histologic examination of the cones confirmed the preoperative diagnosis based on cervical biopsies and the lesion was entirely removed by conization in all cases. Seven of the 8 patients who underwent laser conization during pregnancy had a spontaneous delivery at term. The remaining patient, who had had a previous cesarean section, was again delivered by cesarean section. All treated patients were cured after the first-year follow-up visit. In 6 patients CIN was diagnosed after the sixteenth week of pregnancy. These women underwent cytocolposcopic examination every eighth week during pregnancy and two months after delivery, when the cervical changes associated with gestation had disappeared. Four of these patients showed persistence of CIN at postpartum follow-up and therefore underwent laser conization. In two patients spontaneous regression of the lesion was observed. In no case did progression to invasive carcinoma occur. CONCLUSIONS: Given the increasing incidence of CIN in young women, the beginning of pregnancy may represent a peculiar opportunity for all pregnant women who do not take part in cervical screening programs to undergo a cytocolposcopic examination. In case of a diagnosis of high-grade CIN within the first 16 weeks of pregnancy, a conservative excisional treatment, which does not expose the pregnancy to any risk, should be carried out in order to confirm the intraepithelial localization of the lesion.

ABSTRACT

Many studies have shown a strong correlation between CIN and HPV infection. Molecular biology has allowed identification of types of HPV which seem to be connected, more frequently than others, to dysplastic lesions. Physical state of HPV-genome seems to play an important role in the development of cervical cancer. In this study the HPV-genome has been searched in tissue specimens obtained from 34 women affected by CIN II and III. All patients underwent laser conization. Immediately before treatment, colposcopically directed biopsies of the cervical lesion and of the areas with no colposcopically apparent disease were taken and on these samples, HPV-DNA has been searched, isolated and analysed for HPV types and physical state. Histologic examination on cones showed 6 cases of CIN II (3 with HPV), 24 cases of CIN III (14 with HPV), 1 microinvasive carcinoma and 3 with no residual lesion. Southern blot analysis detected HPV-DNA in 4 cases of CIN II (16.7%) and in 20 cases of CIN III (70.6%). In 50% of CIN II and 85% of CIN III HPV 16 DNA has been found and in the remaining 50% of CIN II and 15% of CIN III HPV 31 DNA has been detected. All CIN II and 14 cases of CIN III showed episomal HPV-DNA. Integrated HPV-DNA has been found in 3 cases of CIN III and the other 3 cases of CIN III showed both integrated and episomal HPV-genome. Integrated form has been noticed only for HPV 16 type. In no case of colposcopically normal tissue has HPV-DNA been found. These data seem to confirm the strong correlation between HPV 16 type, which often has integrated form, and CIN III strengthening the hypothesis of its potential oncogenic action.

ABSTRACT

In this study prevalence of cervical intraepithelial neoplasia (CIN) and genital condylomatosis in HIV-positive women and the possible relation between HIV and HPV infection and CIN have been analyzed. 66 seropositive women underwent cytological, colposcopic and, when necessary, histologic examination and the results have been compared with those obtained from 150 HIV-seronegative controls. HIV-positive patients were divided in two groups, depending on number of CD4+/mm3, < 400 or > = 400, to evaluate the relation between immunity and HPV infection and/or CIN. 35 seropositive and 136 seronegative patients affected by genital condylomatosis and/or CIN I were submitted to laser CO2 vaporization and the results of the treatment have been compared. All cases of CIN II and III underwent laser CO2 conization. Among HIV-seropositive patients the prevalence of genital condylomatosis appeared to be 87.9% and among the seronegative controls 18% (p < 0.001). Multilocated condylomatosis represented 58.7% of genital condylomatosis among seropositive women and 11.1% among the seronegative patients. In HIV-seropositive group the prevalence of genital condylomatosis was of 95.2% among women with CD4+ < 400 and of 75% among those with CD4+ > = 400 (p > 0.01). 13 patients (19.7%) of the 66 seropositive women and 12 of the 150 (8%) seronegative had a cervical intraepithelial neoplasia. A CIN III was diagnosed in 9 seropositive patients (13.6%) and in 5 seronegative (3.3%). Among the HIV-seropositive women who underwent laser vaporization for genital condylomatosis a cure-rate of 34.5% was found; among seronegative women who underwent the same treatment the cure-rate was of 79.4%. Those patients who underwent laser conization resulted all cured at first check. In the group of HIV-seropositive women a higher prevalence (p < 0.001) of genital condylomatosis, particularly multilocated localization, has been found than in HIV-seronegative patients. An increased prevalence of CIN has also been found among HIV-seropositive women. Genital condylomatosis in seropositive patients resulted extremely difficult to treat with laser vaporization in contrast with the 100% success in laser conization for high-grade CIN.

ABSTRACT

The ethical foundation supporting legislation on medical devices deals with safeguard of both individual and collective rights in health care and protection; there is no ethical reason in protecting individuals from reuse of medical devices, if reuse can be proved safe and efficacious, and if it is a way to ensure provision of services otherwise unextendable to all patients, due to lack of funds. This paper explores legal feasibility of reuse, and provides an interpretation of relevant legislation, with special concern on European Directives on Medical Devices. Whereas it is commonly accepted that controls can be imposed to test whether devices meet legal standards on safety and adherence to label indications, clinical investigations and research may as well illuminate different and wider features of the same items, not considered by the manufacturer and not included in the actual labelling. The present wording of the directives does not provide for an autonomous role of member states in asking for modifications in the provisions of the manufacturer, except when devices do not meet specific requirements stated by the directive. Nevertheless, there is no legal ground to emphasize labelling when contrasting with clinical research findings, thus leading to the conclusion that widening a possible manufacturer's understatement in therapeutic uses of medical devices is legally feasible. In the present situation in which responsibility for casualties from reused medical devices is unduly vested on physicians, Health Authorities in member States bear a moral responsibility in promoting adequate research trials to support safety and efficacy of reuse practices, thereby prompting manufacturers to apply for label modification.

ABSTRACT

Analisou-se os resultados de conizaçäo ambulatorial com laser em 468 pacientes selecionadas, portadoras de Neoplasia Intra-epitelial Cervical, independente da presença de infecçäo por Papiloma-vírus humano. As indicaçöes constaram em todos os graus II ou III, grau I com colposcopia prejudicada quanto à junçäo escamo-colunar, inexistência de correlaçäo entre citologia, colposcopia e histologia. O achado de 3,4 por cento de carcinoma invasor apoia o tratamento excisional. Conclui-se que o método representa a melhor escolha nesses casos, face à baixa morbidade e elevada eficácia

ABSTRACT

39 patients affected by CIN had undergone radio surgical excision. This non-traumatic method employs 3.8 MHz radio waves are employed to cut and/or coagulate. The radio surgical excision was carried out by a loop electrode, or microneedle, according to the colposcopic, histologic and microcolpohysteroscopic characteristics of the cervical lesion. In fact 14 patients, among whom 11 affected by CIN I and 4 by CIN II with a total visibility of squamous columnar junction and not extended lesion of the cervical canal, had undergone radio surgical excision through various dimensions loop according to the size of the tissue to be excised. Whereas 10 CIN II patients who had not entirely visible squamous columnar junction or large cervical canal lesion, and 14 CIN III patients underwent to radiosurgical conization through a subtle and extensible tungsten thread according to the size of the tissue to be excised. In the 100% of the both groups the recovery was confirmed after three and six months. Inno cases cervical canal stenosis was observed and the squamous columnar junction resulted well visible. In both groups no thermal damages on the excised tissue, which could create difficulties on the histological diagnosis, were observed. Therefore, this method resulted an easy and cheap technique to be executed in surgery with excellent results under the therapeutic and economical aspect.

ABSTRACT

AIMS AND BACKGROUND: Interferons (IFN) have offered considerable advances in the therapy of genital warts even those associated with cervical intraepithelial neoplasia (CIN); intralesional therapy either alone or in combination with other modalities such as cryosurgery and laser surgery provides improved clearing and cure of these often recalcitrant lesions. The purpose of this study was to evaluate the effectiveness of intralesional IFN therapy in patients with CIN associated with human papillomavirus (HPV) infection. METHODS: Beta-IFN was injected intra-perilesionally into the cervix in 41 patients with CIN associated with HPV infection. RESULTS: The regimen of 3 million international units (IU) injected intralesionally daily in the 1st week and 3 times a week in the 2nd and 3rd weeks for a total of 11 injections and a total dosage of 33 million IU yielded an 80 percent cure rate and may be more advantageous than other treatment options in certain instances. Cytocolposcopic and histologic examination was carried out before and after treatment and 24 lesions were also analyzed for type-specific papillomaviruses using in situ DNA hybridization. CIN disappeared in 33 patients 6 months after the end of therapy. Side effects of intralesional IFN therapy are dose related and for the most part readily tolerated. CONCLUSIONS: Intralesional IFN proved to be effective treatment for CIN associated with HPV infection (cure rate: 80%) and well accepted because hospitalization is not required and no important side effects occur.

ABSTRACT

Vestibular papillomatosis of the vulva is only by some authors considered as a viral lesion, and its origin is controversial. A study of 44 women with vestibular papillomatosis was undertaken, and in all the cases biopsies of vulvar skin were taken. We did not reveal any presence of koilocytotic change suggestive of viral infection, and no human papillomavirus sequences were detected by DNA probe technique. These results suggest that this vestibular papillomatosis of the vulva can be considered as an anatomical variant of the vestibular mucosa. Only in case of viral over-infection, ablative treatment is justified.
