Long-term clinical outcomes in critical limb ischemia--A retrospective study of 181 patients.

OBJECTIVE: Critical limb ischemia (CLI) is the most severe manifestation of the peripheral arterial disease. To date, several prognostic factors have been identified but the data of long-term follow-up in real life setting are scarce. The aim of our study is to describe a large group of CLI patients and identify possible prognostic factors, in a long-term follow-up. PATIENTS AND METHODS: Case-control, retrospective study. 181 consecutive CLI patients with a minimum follow-up of 5 years were included in the study. RESULTS: Overall mortality was 15%, 24%, and 43% at 1, 2, and 5 years, respectively. Among known risk factors, only arterial hypertension was significantly correlated with survival rate; no differences were found between diabetics and non-diabetics. Patients treated with intravenous iloprost (46%), compared to untreated patients, showed a better (p < 0.0001) long-term outcome in terms of major amputation (6% vs. 21%), subsequent vascular surgery (4% vs. 32%) and survival rates (69% vs. 47%), at 5-year follow-up. Major amputations were significantly correlated with lower median forefoot transcutaneous values of O2 (0/3 mmHg, p < 0.001) and higher median values of CO2 (83/53 mmHg, p < 0.0001) in supine/dependent position, respectively. CONCLUSIONS: Our results confirm the poor prognosis of CLI patients in a very long-term follow-up and the severe metabolic damage caused by ischemia. A favourable role of iloprost was observed, in agreement with previous evidence in the literature.

Is the 2003 ISSVD terminology and classification of vulvodynia up-to-date? A neurobiological perspective.

This paper aims to determine if the 2003 International Society for the Study of Vulvovaginal Disease (ISSVD) terminology and classification of vulval pain is up-to-date, according to a current and widely accepted neurobiological pain classification, which divides pain into nociceptive, inflammatory and pathological pain with the latter subdivided into neuropathic and dysfunctional pain. Nociceptive pain is protective, adaptive, high-threshold pain provoked by noxious stimuli. Inflammatory pain is protective, adaptive, low-threshold pain associated with peripheral tissue damage and inflammation. Pathological pain is non-protective, maladaptive, low-threshold pain caused by structural damage to the nervous system (neuropathic pain) or by its abnormal function (dysfunctional pain). The 2003 ISSVD vulval pain classification should be revised in terms of current neurobiological pain information. Inflammatory vulval pain occurs as a result of specific infectious, inflammatory and neoplastic disorders. Neuropathic vulval pain arises following a specific neurological disorder, responsible for structural damage to the nervous system. Vulvodynia is dysfunctional vulval pain, caused by abnormal function of the nervous system itself.

Provoked vestibulodynia: inflammatory, neuropathic or dysfunctional pain? A neurobiological perspective.

This paper aims to clarify the nature of the pain in provoked vestibulodynia (PV). It reviews published data about the nature of the pain in PV, employing a recent pain classification, which divides pain from a neurobiological perspective, into nociceptive, inflammatory and pathological pain, with the latter subdivided into neuropathic and dysfunctional pain. Nociceptive pain is high-threshold pain provoked by noxious stimuli; inflammatory pain is adaptive, low-threshold pain associated with peripheral tissue inflammation; pathological pain is maladaptive, low-threshold pain caused by structural damage to the nervous system (neuropathic) or by its abnormal function (dysfunctional). Most of the published data show that in PV, there is no active peripheral tissue inflammation. Similarly, no neural damage has been demonstrated. It is reasonable to consider PV as dysfunctional pain induced by exposure to acute physical or psychological precipitating events in the presence of an individual predisposition to produce or maintain abnormal central sensitisation.

Ectopic lingual thyroid tissue and acquired hypothyroidism: case report.

Ectopic thyroid tissue with thyroid gland in its normal location is an extremely rare phenomenon. We present a case of a 38-year-old woman who was referred to our hospital with symptoms of hypothyroidism. Thyroid hormone measurement revealed clinical hypothyroidism with elevated anti-thyroid antibodies, neck ultrasonography showed a small tissue with the characteristic of Hashimoto thyroiditis, while the scintigraphy demonstrated only a lingual thyroid. Treatment consisted in L-thyroxine replacement to the euthyroid state. We reviewed the literature with respect to the embryological background and the clinical management of such cases.

Primary "breast-like" cancer of the vulva: a case report and critical review of the literature.

Ectopic mammary gland tissue in the vulva is an uncommon clinical or pathologic finding. Such ectopic tissue can be the site of the same physiologic and pathologic processes found in the normal breast. However, the occurrence of adenocarcinoma is very rare, the first case being reported by Greene in 1935. We here report the 16th case of primary "breast-like" cancer arising in the vulva, together with a critical review of the literature, in order to highlight the dilemmas of a clinical approach to this neoplasm. Clear guidelines for diagnosis and therapy are still unavailable. The main diagnostic criteria suggested by the authors of previous reports are discussed together with our own findings. The therapeutic approach to this rare malignancy is also critically reviewed. In our opinion, when diagnosis of breast-like vulvar cancer is finally confirmed, treatment and follow-up should be the same as that would be chosen in a case of orthotopic breast neoplasm.

Cost-effectiveness of fine-needle-aspiration cytology of thyroid nodules with intranodular vascular pattern using two different needle types.

OBJECTIVE: To compare the cytological findings of hypoechoic thyroid nodules with intranodular vascular pattern (pattern II) obtained by two different needles (Neolus 25 gauge, Chemil, Wenzhou, China vs Yale Spinal 25 gauge, Becton Dickinson, Madrid, Spain) in euthyroid patients and to evaluate their cost-effectiveness. METHODS: From January 2001 to December 2003, 480 euthyroid patients with a hypoechoic thyroid nodule pattern II were referred for US-FNAC. The nodules were alternatively evaluated by Neolus or by Yale Spinal with the stylet (YS+) or without the stylet (YS-), in order to evaluate if the cytological results could be due to the presence of the stylet or to the different length of the two needles. For each nodule two passes were performed and the material was obtained by capillary action. Material was smeared on slides, fixed, and stained by Papanicolaou techniques. Cytological specimens were evaluated in blind by the same experienced cytopathologist. RESULTS: Inadequate cytological specimens because of blood contamination were present in 30 (18.7%) samples by Neolus needle and in 22 (13.8%) by YS- compared to only 5 (3.1%) by YS+. In 6 (20%) cases of the 30 repeated US-FNAC by Neolus and in 4 (18%) of the 22 US-FNAC by YS-, material remained inadequate for diagnosis because of blood contamination. All the five repeated samples obtained by YS+ became adequate for diagnosis and resulted benign nodules. Direct costs of US-FNAC procedure are currently 72.30 Euro including cytological examination. The cost of Neolus and Yale needles is 0.19 Euro and 3.0 Euro, respectively. The estimated total cost to obtain a cytological diagnosis by a Neolus needle (160 + 30 repeated US-FNAC) was 13809.2 Euro vs 12919.5 Euro by Yale Spinal needle (160 + 5 repeated US-FNAC). CONCLUSION: This study demonstrates that the use of Yale Spinal needles greatly reduces inadequate cytological specimens, and therefore limits both direct and indirect costs.

[Vulvar lesions caused by HPV]. / Lesioni vulvari da HPV.

Human papillomavirus subclinical lesions are well known on the cervix and are identified by colposcopy after acetic acid staining. The transfer of this technique from the cervix to the vulva has led to the identification of areas of white epithelial changes which have been defined by similarity as vulvar subclinical HPV (VSHPV) lesions. A critical revision of the different clinical VSHPV lesions classifications, the vulvar diagnostic role of acetic acid staining, the natural history of HPV infection and the histological-biomolecular diagnostic techniques has the authors to the conclusions that the majority of the "so called" VSHPV lesions should not be considered a real disease. The presence of HPV-DNA in these subclinical lesions should be considered causal and not causal. To avoid overtreatments in women with proven HPV-DNA positivity without macroscopic clinical lesions, the authors recommend to abandon the acetic acid staining on the vulva and invite to consider the VSHPV lesions a faked diagnosis and not a clinical entity.

[Vulvar Paget's disease. Clinico-pathologic review of the literature]. / La malattia di Paget vulvare. Revisione clinico-patologica della letteratura.

In 1986 the International Society For the Study of Vulvar Disease classified vulvar Paget's disease (VPD) as a non-squamous intraepithelial lesion of the vulva. The clinical multiform aspect of VPD, similar to other dermatological lesions, often delays the execution of a biopsy. Paget's cells could be instead easily identified at histological examination and with histochemical reactions. Underlying adenocarcinomas or stromal invasion are present in about 10% of intraepithelial VPD. Patients with VPD are at risk for a second synchronous or metachronous neoplasia: colo-rectal adenocarcinoma (more frequent in perianal localization of VPD), cervical adenocarcinoma, carcinoma of the transitional epithelium from the renal pelvis to urethra and mammary carcinoma. A wide spectrum of frequency of these associations is reported in the literature (0-45%). Therapy for intraepithelial VPD is wide and deep surgical resection comprising all the skin appendages. However VPD has a high frequency of recurrences (15-62%), often irrespective for radicality of surgical excision. When association with underlying invasive adenocarcinoma or stromal invasion is histologically confirmed, vulvar surgical approach must be integrated with inguino-femoral lymphadenectomy. The role of chemotherapy and radiotherapy in the multimodal approach to extensive or recurring VPD is still controversial. Recurrences or progression of intraepithelal VPD are reported more than 10 years from first surgical resection so that long term follow-up is mandatory.

Recurrent squamous cell carcinoma of the vulva: clinicopathologic determinants identifying low risk patients.

BACKGROUND: The identification of prognostic factors in the recurrence of vulvar squamous cell carcinoma is crucial for less invasive treatments. METHODS: The authors studied 101 patients treated for primary invasive squamous cell carcinoma of the vulva. Selected pathologic variables were observed in a standardized manner during treatment, and their association with disease free survival was investigated using the Cox model. Independent prognostic factors were selected by a stepwise procedure. The absolute survival of patient groups determined on the basis of such factors was computed by the product limit method. RESULTS: The median follow-up was 3.1 years (range, 56 days to 15.5 years). Recurrences developed in 33 patients. The independent recurrence predictors were as follows: International Federation of Gynecology and Obstetrics (FIGO) Stage IVA (vs. IB, II, or III) (risk ratio [RR]adjusted for other independent factors, 7.39), tumor multifocality (RR, 4.10), lymphovascular space involvement (LVSI) (RR, 2.96), the presence of associated vulvar intraepithelial neoplasia (VIN) Grade 2 or 3 (RR, 3.34), and the involvement of resection margins (RR, 4.88). By ignoring the FIGO stage and lymph node status, the independent predictors were then as follows: greatest tumor dimension < 2.5 cm, 2.5-4 cm (RR, 2.86), or > 4 cm (RR, 5.98); tumor multifocality (RR, 3.36); LVSI (RR, 4.19); the presence of VIN 2 or 3 (RR, 3.06); and the involvement of surgical margins (RR, 2.78). No recurrences were observed in 119 at-risk years among patients with unifocal tumors < 2.5 cm in greatest dimension, free surgical margins, no LVSI, and no associated VIN 2 or 3. CONCLUSIONS: The presence of associated VIN 2 or 3 was revealed to be a previously unidentified independent prognostic factor for recurrence. Subjects at low risk of recurrence could be identified even without consideration of lymph node status.

[Vestibular papillomatosis]. / La papillomatosi vestibolare.

The aim of the present study is to re-update the clinical significance of vestibular papillomatosis. At the beginning of the eighties this condition has been related to HPV infection based on histological and/or molecular evidence of the virus presence and considered responsible of many cases of pruritus and/or vulvodynia. Based upon these findings a lot of clinicians have been treating this condition by laser ablation or by topical application of podophyllin or trichloroacetic acid. At present the majority of the authors believes that vestibular papillomatosis should be considered an anatomical variant of the vestibular mucosa not HPV related. Therefore HPV-DNA presence should be considered a causal rather than a causal agent. This evidence is important in defining the management of vestibular papillomatosis: the papillae are usually distinguishable from condylomata acuminata by clinical examination and biopsies or HPV testing are not necessary. According to the studies considering vestibular papillomatosis a non HPV related condition and on the bases of a series of 252 women examined, the Authors share the opinion that this clinical entity should be considered a normal vestibular findings. As a consequence no ablative treatment is usually required even if in presence of symptomatology or HPV molecular infection.

Anatomosurgical implications derived from an embryological study of the Scarpa's triangle with particular reference to groin lymphadenectomy.

OBJECTIVE: To clarify some anatomical controversies of the fascial structures and lymph node development of the inguinal region through an embryological study in relation to the surgical techniques of groin lymphadenectomy. METHODS: Sections of the femoral triangle belonging to four fetuses whose crown-rump (CR) length ranged from 70 to 310 mm, corresponding to a developmental age of 11 and 35 weeks, were studied. RESULTS: The femoral fascia is formed of one layer and is not divided into superficial and deep layers. The cribriform fascia has a morphogenetic origin different from that of the femoral fascia and it is defined by the thickening of the connective tissue filling the fossa ovalis and therefore would be more correctly named lamina cribrosa. The deep inguinal lymph nodes originate directly from the superficial lymphatic tissue located in the fossa ovalis. This last observation supports the fact that no lymph nodes are present beneath the femoral fascia distal to the lower margin of the fossa ovalis. CONCLUSIONS: The results of this study, from a surgical point of view, support the technique of total or radical inguinal-femoral lymphadenectomy with preservation of the femoral fascia and, from an anatomical point of view, resolve some of the contradictory statements reported in the anatomical literature regarding morphogenesis and terminology of the structures of the Scarpa's triangle. In addition, the present study provides useful anatomic and terminological landmarks to those surgical oncologists (gynecologist, urologist, dermatologist, etc.) dealing with malignant diseases requiring groin dissection practices. In addition, it could represent a useful background for a future more precise surgical terminology which represents a vital issue for institutional studies with multiple surgeons as well as for large multi-institutional studies.

A proposed glossary of terminology related to the surgical treatment of vulvar carcinoma.

BACKGROUND: The authors' objective was to provide a glossary of terminology related to the surgical treatment of invasive vulvar carcinoma. There is currently no consensus in the literature regarding the names of the surgical procedures used to treat this disease. METHODS: A surgical glossary should be supported by clear definitions and acceptance of notions related to topographic anatomy that are specific to the surgical practice. A critical review of the classic, chiefly used Italian, French, German, and English textbooks of anatomy revealed some discrepancies and lack of uniformity in descriptions of vulvar and inguinal fascial structures and lymph nodes, which represent the principal landmarks of surgical treatment. In the proposed glossary, the descriptions of these anatomic landmarks integrate classic anatomic knowledge, data from recent gynecologic studies of inguinal anatomy, and the clinical experiences of the authors. RESULTS: The glossary is composed of 16 surgical definitions, which are divided into 3 main sections of terminology describing the surgical treatment of the: 1) vulva, 2) inguinal lymph nodes, and 3) pelvic lymph nodes. The fundamental objective behind the glossary is to describe the area and the depth of the surgical procedure. Three determinants of the area (local, partial, and total) and three determinants of the depth of surgery (superficial, simple, and deep) were used to arrive at the fully articulated definitions in the glossary. CONCLUSIONS: The authors are aware that the proposed glossary should not be considered a definitive one; however, it could serve as a good basis for further debate. The terms employed in the glossary are accompanied by anatomic and descriptive references to help avoid confusion and promote better understanding among gynecologic oncologists who are involved in the treatment of vulvar carcinoma.

Risk factors associated with taeniasis-cysticercosis in Lagamar, Minas Gerais State, Brazil.

An epidemiological survey was carried out in 3,344 people of an urban town in Lagamar, Minas Gerais, Brazil--during 1992-1993, to evaluate the main risk factors related to taeniasis and cysticercosis. A total number of 875 (78.9%) houses were visited and 1080 (32.3%) subjects were clinically examined. Poor sanitary conditions were positively associated with former history of taeniasis or seizures in households (p < 0.05). It was remarkable the positive relationship between taeniasis and seizures when households were questioned and subjects were clinically evaluated (p < 0.05). The relative risk of seizures was 2.3 between households and 1.7 for individuals clinically examined respectively. The breeding of swine nearby and the chronic carriers of taeniasis are determinant factors in the maintenance of the epidemiological link between taeniasis and cysticercosis in endemic areas.

Foi realizado inquérito epidemiológico em 3344 indivíduos da área urbana de Lagamar, Minas Gerais, Brasil, durante 1992-1993 para avaliar os principais fatores de risco relacionados com teníase e cisticercose. Foram visitadas 875 (78,9%) casas e examinados clinicamente 1080 (32,3%) indivíduos. As condições sanitárias deficientes estiveram associadas estatisticamente com história anterior ou atual de teníase ou de convulsões entre os membros de cada família (p < 0,05). A correlação entre teniase e convulsões foi evidenciada tanto no inquérito domiciliar como durante a avaliação clínica dos indivíduos (p < 0,0001). O risco relativo de convulsões foi de 2,3 entre os moradores entrevistados no domicílio e 1,7 entre os indivíduos que compareceram para exame clínico, respectivamente. A criação de suínos no peridomicílio e os portadores crônicos de teníase são fatores determinantes na perpetuação do elo epidemiológico teníase-cisticercose nas áreas endêmicas.

Periodontal disease, oral microbial flora and salivary antibacterial factors in diabetes mellitus type 1 patients.

One hundred and thirty-one patients with diabetes mellitus type 1 (IDDM) and 20 healthy controls were checked for the presence of periodontal diseases and for some oral microbiological parameters. Results demonstrated that IDDM patients, who were well compensated from both the metabolic and clinical point of view, showed a prevalence for periodontopathies, which only differed slightly from controls. Only the presence of gingivitis was significantly higher in IDDM patients than in healthy subjects. Both anaerobic and aerobic microbial flora did not show substantial differences for either group. Among the salivary antibacterial factors studied, lysozyme was significantly decreased in diabetic patients compared to controls. It is concluded that IDDM patients undergo periodontal complications with a frequency quite close to that of non-diabetic healthy subjects, when the disease is under strict metabolic and clinical control.

[Role of radiotherapy in the combined treatment of invasive cancer of the vulva]. / Ruolo della radioterapia nel trattamento integrato del carcinoma invasivo della vulva.

The authors review the literature on the different combinations of radiotherapy with chemotherapy and surgery with the aim of giving a state of art on the role of combined multimodality treatment of invasive vulvar carcinoma. From the data of the recent literature it appears that radiation integrated with surgery and chemotherapy can play an important role in reducing the risk of postoperative locoregional failure in patients with advanced primary or nodal disease and avoiding exenteration in patients with disease involving the anus or proximal urethra. This integrated multimodality therapy is a promising approach in the treatment of invasive vulvar carcinoma but further exploration in a larger number of patients is needed before giving consolidated data applicable in routine oncological clinical practice.

[The epidemiological aspects of taeniasis-cysticercosis in an endemic area of Lagamar, Minas Gerais]. / Aspectos epidemiológicos da teníase-cisticercose na área endêmica de Lagamar, MG.

An epidemiological inquiry of humancysticercosis due to Taenia solium was carried out in Lagamar, Minas Gerais State, Brazil, in 1992. A survey of 1109 houses with 3344 inhabitants was made. The inquiry included 875 (86%) families and the questionnaire was answered by an informer, who was the father in 80% of the cases. One hundred pigsties, sheltering 406 swines in extremely precarious conditions, were found in 100 (11.4%) houses. A history on taeniasis in some member of the family was verified in 300 (34.2%) houses. A history of seizures was referred to by 125 (14.2%) of families. The outset of convulsion in adult age was characterized in 39 (37.8%) families. A history of mental disorder was reported in 53 (6.0%) of houses. Stool examinations were positive for Taenia spp in 24 (1.3%) of samples examined.

[Terminology and classification problems in relation to vulvar pathology]. / Problematiche classificativo-terminologiche relative alla patologia vulvare.

The aim of this paper is to update the physicians (gynecologists, dermatologists and pathologists) on the evolution of vulvar disease terminologies. In doing that the authors illustrate briefly the fundamental steps which led to present classifications of the International Society for the Study of Vulvar Disease (ISSVD). The classification of "non neoplastic epithelial disorders" together with that of "intraepithelial alterations" are illustrated and compared with the terminologies previously employed. The last ISSVD definition of "superficially invasive carcinoma" of the vulva is also presented and discussed. The authors concluded that even if all these ISSVD classifications represent an important effort for reaching a common language for a better international exchange of different experiences, nevertheless an improvement of these terminologies is still requested.

Beta-interferon treatment of cervical intraepithelial neoplasia: a multicenter clinical trial.

Forty-nine women with cervical intraepithelial neoplasia (CIN) grade II were treated with systemic and/or local beta-interferon (beta-IFN) applications. The aim of the study was to compare the efficacy of different routes for the administration of beta-IFN, evaluate local and systemic beta-IFN tolerance, and determine whether disappearance of neoplastic lesions was related to the resolution of the concomitant human papillomavirus infection. The patients were randomized to receive intramuscular, intralesional or a combination of intramuscular and intralesional administration, or conventional treatment. Significant differences in the rate of lesion regression were observed between treated and untreated women. The highest frequency of complete response was observed with the therapy combining intramuscular and intralesional treatment.
