Oral HPV Infection in Women with HPV-Positive Cervix Is Closely Related to Oral Sex.

The oral transmission of HPV and, consequently, the risk of oral cancer has increased in the last years. Oral sex has often been implicated among the risk factors for oral HPV infections, however, there is still no consensus on these topics, nor on the relationship between genital and oral HPV infections. The present study aimed to evaluate the coexistence of papilloma virus, at the levels of the oral and genital mucosa, in women with a histologically confirmed HPV lesions (and a positive HPV test) at the genital level and a negative HPV control group. We also evaluated how some risk factors, such as smoking, the number of partners, age, and sexual habits can influence the possible presence of the virus itself in the oropharynx of the same women. In total, 117 unvaccinated women aged between 18 and 52 were enrolled. We found that the prevalence of oral HPV infection was high among the women with concomitant genital HPV infection (22%) compared to the HPV-negative women (0%), and the estimated odds ratio was 17.36 (95% CI: 1.02, 297.04). In none of the women with oral HPV did we find any relevant clinical lesions. The potential risk factors for HPV infections in the oropharynx and genitals were analyzed based on questionnaire responses. A multivariate analysis showed that genital HPV infections were significantly associated with a number of sexual partners > 10 (OR 138.60, 95% CI: 6.04-3181.30, p < 0.001), but the data also referred to having between 3-5 or 6-10 partners as being significant, as were a high level of education (OR 6.24, 95% CI: 1.67-4.23.26 p = 0.003), a frequency of sexual intercourse >10 (OR 91.67 95% CI: 3.20-2623.52, p = 0.004), oral sex (OR 6.16, 95% CI: 1.22-31.19, p = 0.014), and >20 cigarettes/day (OR 6.09 95% CI: 1.21-30.61, p = 0.014). Furthermore, being "separate" and having multiple sexually transmitted diseases were also significantly associated with genital HPV infection. In contrast, oral HPV infections were significantly associated with women aged 36 to 50 years (OR 27.38, 95% CI: 4.37-171.37; p = 0.000202) and oral sex (OR 95.5, 95% CI: 5.13-1782.75, p = 0.001126).Additionally, being separate, being cohabitant, lifetime sexual partners of >10, 3-5 lifetime sexual partners, <20 years of age, >10 sexual intercourse per month, occasional and regular anal sex, >20 cigarettes per day, a history of sexually transmitted disease (herpes and multiple), and having a history of genital warts were significant. Screening and early diagnosis are considered to be practically unfeasible for this category of cancer, given the lack of visible lesions; the 9-valent HPV vaccine remains the only means that could help to successfully counter the growing incidence of oral squamous cell carcinoma.

Effects of osteopathic manipulative treatment of the pivots on lower limb function in young professional football players.

INTRODUCTION: The most frequent injuries in professional soccer players are those pertinent to the lower limbs. In particular, strains of the hamstrings and ligamentous injuries of the knee. Therefore, preventive measures are aimed to reduce such events. We aimed to investigate if an osteopathic manipulative treatment (OMT) of the pivots could improve lower limb function in young professional football players. METHODS: Thirty-eight young male professional football players were recruited (mean age 17.8 ± 0.44 years). These were randomly assigned to an OMT or control group (n = 20 and 18, respectively). Both groups underwent osteopathic evaluation. A sit-and-reach test, a vertical jump test, a hand-grip strength test, a cervical ROM test and a balance evaluation were also performed. RESULTS: A significant improvement (p < 0.01) was observed between pre and post measures in the OMT for dysfunctional assessment of the pivots. However, only L3 and C2 also differed from the control group post evaluation (p < 0.0001). No differences were present for any functional measure in the control group. Only the sit-&-reach of the OMT increased significantly (p < 0.001). Static balance with open eyes in the OMT, but not in the control group, improved during post evaluation (p < 0.01). CONCLUSION: The OMT of the pivots was able to increase the sit-and-reach measure, improve postural control with open eyes and improve dysfunctional patterns of the lumbosacral and upper cervical spine in young professional football players.

The efficacy of muscle energy techniques in symptomatic and asymptomatic subjects: a systematic review.

Background: Muscle energy techniques are applied to reduce pain and increase range of motion. These are applied to a variety of pathological conditions and on asymptomatic subjects. There is however limited knowledge on their effectiveness and which protocol may be the most beneficial. Objective: The aim of this review is to determine the efficacy of muscle energy techniques (MET) in symptomatic and asymptomatic subjects. Design: Systematic Review. Methods: A literature search was performed using the following database: Cochrane Library, MEDLINE, NLM Pubmed and ScienceDirect. Studies regarding MET in asymptomatic and symptomatic patients were considered for investigation. The main outcomes took into account range of motion, chronic and acute pain and trigger points. Two trained investigators independently screened eligible studies according to the eligibility criteria, extracted data and assessed risk of bias. Randomized control trials (RCT's) were analyzed for quality using the PEDro scale. Results: A total of 26 studies were considered eligible and included in the quantitative synthesis: 14 regarding symptomatic patients and 12 regarding asymptomatic subjects. Quality assessment of the studies through the PEDro scale observed a "moderate to high" quality of the included records. Conclusions: MET are an effective treatment for reducing chronic and acute pain of the lower back. MET are also effective in treating chronic neck pain and chronic lateral epicondylitis. MET can be applied to increase range of motion of a joint when a functional limitation is present. Other techniques seem to be more appropriate compared to MET for trigger points.

Nanoparticle-Based Delivery of Anaplasma marginale Membrane Proteins; VirB9-1 and VirB10 Produced in the Pichia pastoris Expression System.

Bovine anaplasmosis or cattle-tick fever is a tick-borne haemolytic disease caused by the rickettsial haemoparasite Anaplasma marginale in tropical and subtropical areas of the world. While difficult to express, the proteins VirB9-1 and VirB10 are immunogenic components of the outer membrane type IV secretion system that have been identified as candidate antigens for vaccines targeting of A. marginale. Soluble VirB9-1 and VirB10 were successfully expressed using Pichia pastoris. When formulated with the self-adjuvanting silica vesicles, SV-100 (diameter: 50 nm, and pore entrance size: 6 nm), 200 µg of VirB9-1 and VirB10 were adsorbed per milligram of nanoparticle. The VirB9-1 and VirB10, SV-100 formulations were shown to induce higher antibody responses in mice compared to the QuilA formulations. Moreover, intracellular staining of selected cytokines demonstrated that both VirB9-1 and VirB10 formulations induced cell-mediated immune responses in mice. Importantly, the SV-100 VirB9-1 and VirB10 complexes were shown to specifically stimulate bovine T-cell linages derived from calves immunised with A. marginale outer membrane fractions, suggesting formulations will be useful for bovine immunisation and protection studies. Overall this study demonstrates the potential of self-adjuvanting silica vesicle formulations to address current deficiencies in vaccine delivery applications.

How to avoid a difficult groin in redo arterial surgery: eversion endarterectomy of the proximal superficial femoral artery versus profunda femoris artery as inflow for distal bypass.

BACKGROUND: The aim of the study was to describe and analyze the results of a technique in which the inflow for distal bypasses is provided by the proximal superficial femoral artery, reopened through an eversion endarterectomy, to avoid a "difficult groin." MATERIAL AND METHODS: Twenty-one patients who underwent distal bypass for severe lower-limb ischemia and in whom the proximal superficial femoral artery was reopened with an eversion endarterectomy to provide inflow for the bypass itself were included in the study. As a comparison group, 20 patients in whom the inflow for a distal bypass was obtained by the distal deep femoral artery were randomly selected. In all 41 patients, the groin was considered "difficult" because of multiple previous operations. RESULTS: Five-year cumulative patency rates were 53% for femoropopliteal bypasses and 40% for femorotibial bypasses. Similar patency rates were obtained when the distal deep femoral artery was used as inflow. CONCLUSIONS: Eversion endarterectomy of the proximal superficial femoral artery provides a valid source of inflow for distal bypasses, and it should be kept in the armamentarium of the vascular surgeon, to be used in selected cases.

Eversion endarterectomy of the proximal superficial femoral artery: a source of inflow for distal bypass in case of hostile groin.

BACKGROUND: In selected patients, eversion endarterectomy of the proximal superficial femoral artery can represent a valid inflow for a distal bypass to avoid a "hostile" groin. MATERIAL AND METHODS: Patency rates and limb salvage rates were retrospectively analysed for 21 consecutive patients who underwent distal bypass for severe lower limb ischemia and in whom the proximal superficial femoral artery was reopened with an eversion endarterectomy. In all patients, this technique was used to avoid a hostile groin. RESULTS: Five-year cumulative patency rates were 53% for femoropopliteal bypasses and 40% for femorotibial bypasses. Overall 5-y cumulative limb salvage was 72%. CONCLUSIONS: In case of hostile groin, eversion endarterectomy of the proximal superficial femoral artery is a valid solution to provide inflow for a distal bypass.

Clitoral blood flow changes after surgery for stress urinary incontinence: pilot study on TVT Versus TOT procedures.

OBJECTIVES: To study the effects of mini-invasive surgery using the tension-free vaginal tape (TVT) procedure and the transobturator tape (TOT) procedure in modifying clitoral blood flow in women affected by stress urinary incontinence. METHODS: The setting of the prospective open clinical study was the Urogynecologic Service of the Department of Microbiological and Gynecological Science, University of Catania School of Medicine (Catania, Italy). A total of 105 women underwent surgery; 42 (mean age 52.8 years) and 63 (mean age 53.9 years) were treated with TVT and TOT, respectively. Each woman underwent translabial color Doppler ultrasonography to measure the resistance index, pulsatility index, peak systolic velocity, and end-diastolic velocity of the clitoral arteries, before and 6 months postoperatively. RESULTS: In the TVT group, the mean pulsatility index and mean peak systolic velocity were significantly lower and the mean resistance index was significantly greater compared with the pretreatment values (P <0.5). In the TOT group, each color Doppler measurement was similar to that obtained at baseline (P = NS). CONCLUSIONS: The different vaginal approach for these two surgical methods influenced clitoral blood flow. Our data could add new information about sexual behavior after incontinence treatment, particularly the impact of clitoral blood flow changes.

Intravascular ultrasound in the endovascular management of atherosclerotic peripheral occlusive disease.

This study is a retrospective analysis of the impact of intravascular ultrasound in addiction to conventional angiography in 36 patients with 55 stenotic peripheral arterial lesions treated with angioplasty and/or stenting. Before treatment, intravascular ultrasound imaging showed that the vessel diameter was underestimated with angiography in 6 cases. The correlation index between angiography and intravascular ultrasound measurements, however, was significant in 27 arterial lesions. After endovascular treatment, angiography showed 3 vessel dissections and no incomplete stent deployment, whereas intravascular ultrasound showed 15 dissections and 5 instances of stent underdeployment. If we consider the intravascular ultrasound data as the gold standard, the specificity of angiography is 100%, while its sensitivity is 56% for vessel dissection and 75% for stent deployment. In the follow up of the 16 patients treated for iliac lesions with intravascular ultrasound control, re-stenosis occurred in 5% (primary patency 94.7%); in a control group of 15 patients treated in the same period without intravascular ultrasound control, re-stenosis occurred in 15.8% (primary patency 83.4%, difference not statistically significant). In conclusion, in the peripheral arteries intravascular ultrasound is more accurate than arteriography in evaluating dissection and stent deployment, but the routine use of intravascular ultrasound in every case of iliac PTA or stenting would not appear justified.

Thyroid cancer in patients with hyperthyroidism.

OBJECTIVE: The coexistence of hyperthyroidism and thyroid cancer is considered a rare event. With the aim of assessing the clinical relevance of this association, we have retrospectively analyzed the incidence of thyroid cancer in 425 hyperthyroid patients seen and treated by surgery in our institutions. METHODS: Among these hyperthyroid patients, we observed 241 (56.7%) cases of multinodular toxic goiter, 120 (28.3%) of uninodular toxic goiter and 64 (15%) cases of Graves' disease. RESULTS: Thyroid cancer was diagnosed in 7 (1.65%) hyperthyroid patients. Histological examination revealed the presence of papillary carcinoma in 5 cases and follicular carcinoma in 2 cases. Neoplasia was detected in 4 patients with nodular toxic goiter and in 3 with uninodular toxic goiter. None of the patients with Graves' disease had thyroid cancer. During the follow-up of 74 months (range 4-154), there were no deaths or any recurrences. CONCLUSION: Although the occurrence of thyroid cancer in hyperthyroid patients is a rare event, the presence of a 'cold' nodule in a hyperfunctioning thyroid should be carefully evaluated to exclude the presence of concurrent malignancy.

Preoperative concomitant radiochemotherapy with a 5-fluorouracil plus folinic acid bolus in the combined treatment of locally advanced extraperitoneal rectal cancer: a long-term analysis on 27 patients.

AIMS AND BACKGROUND: Many studies of preoperative chemoradiation in resectable rectal cancer have focused on down-staging and sphincter-saving procedures. The aim of this study was to evaluate long-term outcome in resectable rectal cancer treated with preoperative chemoradiation and surgery by only one surgical team irrespective of the tumor downstaging. MATERIAL AND METHODS: From 1992 to 2001, in a cooperative study between the Institute of Semeiotica Chirurgica and the Division of Radiotherapy of the Catholic University of the Sacred Heart, 27 patients with locally advanced rectal cancer were treated with preoperative chemoradiation, followed by surgery after 4-6 weeks, and, just for 6 of them, by adjuvant chemotherapy. Seventeen patients were staged T3 N1 (63%), 4 patients T3N0 (15%), 4 patients T3N2 (15%) and 2 T4N2 (7.5%). Twenty-three patients (85.1%) had signs of nodal involvement at combined imaging. Radiation therapy was delivered to the posterior pelvis at a dose of 45 Gy to the tumor (clinical target volume) and the whole pelvis (planning target volume). Fractionation was conventional: 1.8 Gy/day, 5 fractions a week. Radiotherapy was started on Monday for all patients and was delivered with a linear accelerator. Concomitant chemotherapy consisted of 5-fluorouracil (350 mg/m2/day, as an intravenous bolus on days 1-5 and 29-33 of radiotherapy) and folinic acid (L-isomer) (10 mg/m2 as an intravenous bolus on days 1-5 and 29-33). This chemotherapy was generally administered about 1 hr before radiotherapy. Data were analyzed on July 2002; median follow-up was 59 months (range, 20-116 months). No patient was lost during the follow-up. RESULTS: All patients completed the treatment. Grade > 3 acute toxicity occurred in 11% of the patients and late toxicity was 15%. A pathologic complete response was recorded in 22% of patients; sphincter-preserving surgery was feasible in 44%. Seven patients died: 2 of them perioperatively, 1 patient died with local recurrence, and 1 died with distant metastases; 3 patients died during the follow-up for other causes. Five-year local control was 95% and overall survival was 84%. CONCLUSIONS: Our study, although limited in number, demonstrated good results in local control and disease-free survival with a limited toxicity.

[Diverticular disease: complications and treatment]. / La malattia diverticolare: complicanze e trattamento.

This study reports on 10 years of experience in observing diverticular disease. The study considers 77 patients, 41 males and 36 females, aged from 50 to 88 years (mean age: 70 years), observed from January 1991 to December 2001. Sixty-two patients were admitted from the Accident and Emergency Unit and 15 were elected patients. Five patients underwent emergency surgery, while 72 received only antibiotic therapy. The overall mortality rate was 0. The morbidity rate was 22% in those patients undergoing emergency surgery. In only one of the elected patients was wound suppuration detected. Diverticular disease, in most cases, is treated by antibiotic therapy alone, but in 30% of cases surgery is necessary. Colon resection and immediate anastomosis are the first choice operation also in the emergency setting, provided local conditions (inflammation, septic contamination) make anastomosis safe. In patients with major peritoneal contamination, Hartman's operation and subsequent recanalization after 6 months are to be preferred.

Benign multicystic mesothelioma of the peritoneum: a case report.

The aim of this study is to report the experience of a case of benign multicystic mesothelioma of the peritoneum presented with acute appendicitis symptomatology. A 28 years old man with right lower and upper abdominal pain was admitted into hospital. Because of the clinical picture, the symptomatology and the leukocytosis a diagnosis of acute appendicitis was made and the patient underwent appendicectomy according to Mc Burney. At laparotomy some cc of purulent fluid were sucked and a cystic mass that contained clear fluid was revealed. In consequence of the incidental diagnosis a following middle laparotomy was made with a careful surgical excision of the mass and of the appendix. Macroscopically the lesion was identified like a neoplastic mass 25 centimeters in diameter, with a multicystic and fibrous-adipose aspect, with cysts 5 centimeters in diameter. The cystic spaces were lined by a layer of eptelial cells which presented positive reaction for cytokeratin and EMA, whereas endothelium markers were absent. The ultrastructural, morphological and immunohistochemical findings were diagnostic of a benign multicystic mesothelioma.
