Percutaneous minimally invasive management of iatrogenic ureteral injuries.

PURPOSE To present experience with the percutaneous management of iatrogenic ureteral injuries. PATIENTS AND METHODS Eighteen women and six men with a mean age of 59.3 years (range 33-80 years) received a diagnosis of ureteral injury sustained during gynecologic, urologic, and general surgical procedures. In a total of 25 injured ureters, 12 had interruption of continuity of their lumen, 10 were associated with contrast extravasation, and 3 were related to both. A standard percutaneous nephrostomy tract was established on the side of the afflicted kidney. Combined use of hydrophilic guidewires and balloon dilations were performed to achieve antegrade recanalization of the ureteral lesion. Then, a ureteral stent was inserted to assure patency. RESULTS Average stricture length was 1.21 (range 0.5-1.9 cm). Success of the aforementioned technique was possible in 18 ureters. Successful management in one session took place in 14 ureters. Average hospitalization time was 1.8 days (range 0-5 d). The follow-up period ranged between 12 and 18 months, with mean follow-up time of 12.9 months. Ureteral patency was evident at 1 week follow-up in six patients with obstructed ureters. In the remaining patients, balloon dilation of the stricture was repeated, and another stent was placed. Extravasation of contrast was observed in two patients with extravasating ureters in the same period. Nephrostomy tubes were removed after a mean indwelling period of 5.9 weeks (range 1-12 wks). Two patients treated by the described method died during their hospitalization in the intensive care unit because of sepsis from peritonitis that was related to colon injury and multiple concomitant injuries. Major complications were not observed in the remaining 22 patients during the follow-up period. CONCLUSION The minimally invasive management of ureteral injuries is a safe and efficient method for both ureteral obstruction and/or laceration in a wide range of iatrogenic ureteral injuries.

Successful pregnancy outcome in a patient with primary Addison's disease

A 32-year-old primigravida with primary Addisons disease was followed up from the early stages of pregnancy to delivery and puerperium by a multidisciplinary medical board. Besides fetal surveillance, great attention was given to steroid replacement therapy in order to avoid complications. Vaginal labor resulted in the birth of a healthy neonate that performed well.

Expression and potential role of ErbB receptors in type II endometrial cancer

OBJECTIVE Endometrial cancer is the most common malignancy of the female genital tract. Based on clinical and pathological features, endometrial cancer is classified into two types. The aim of our study was to describe the expression and the potential clinical role of ErbB receptors in Greek patients with type II endometrial cancer. STUDY DESIGN Between 1991 and 2008, 10 women with histologically confirmed type II endometrial cancer were referred to the Department of Gynecologic Oncology of the University of Patras Medical School. Tissue specimens from endometrial lesions were immunostained for EGFR, ErbB-2, ErbB-3 and ErbB-4. RESULTS For EGFR, 5 cases were positive (50%) and 5 cases were negative. For ErbB-2, 9 cases were positive (90%) and 1 case was negative. For ErbB-3, all cases were positive. For ErbB-4, 7 cases were positive (70%) and 3 cases were negative. Also for all ErbB receptors, 5 cases were positive (50%). During follow up, 3 patients died from their disease. All of them had papillary serous endometrial cancer and 2 of them were positive for all ErbB receptors. CONCLUSION Although our study was based on a small number of cases, it is obvious that we had high expression levels of ErbB receptors in patients with type II endometrial cancer. Also the majority of patients with dismal outcome were positive for all ErbB receptors. This is very important, as ErbB-targeted therapies may be clinically active as adjuvant therapy in well-defined subgroups of type II EC patients with EGFR and ErbB-2 overexpression.

serum Thyroglobulin Concentration Is a Weak Marker of Iodine Status in a Pregnant Population with Iodine Deficiency

Objective: To assess the reliability of thyroglobulin (Tg) as a marker of iodine status during pregnancy. Design: 299 women aged 30.5 ± 4.8 years (mean ± SD) were studied. Methods: In every subject, we measured urinary iodine concentration (UIC), serum thyrotropin (TSH), Tg, free thyroxine (fT4), Tg autoantibodies (TgAbs) and human chorionic gonadotropin (hCG) levels. We excluded samples with increased TgAbs from the analysis. Results: According to WHO criteria, the study population was iodine deficient in every trimester. Serum Tg levels did not differ during the three trimesters of pregnancy. Serum hCG levels fell significantly as pregnancies advanced. A weak, significantly negative correlation (limited to the 3rd trimester) was found between Tg and UIC (ρ = -0.187, p = 0.039). Serum fT4 decreased as pregnancies advanced and TSH increased. Serum fT4 was negatively correlated with TSH (ρ = -0.161, p = 0.006) and positively with hCG (ρ = +0.165, p = 0.005). The multiple regression equation of Tg based on hCG, TSH, UIC and trimester of pregnancy was significant but weak (F = 4.057, p = 0.003; R2 = 0.055), with hCG as a significant predictor Tg (p for log hCG = 0.041). Conclusions: Tg cannot be considered as a valid marker of iodine deficiency in pregnancy, at least in a mildly iodine-deficient environment. Further studies in a larger patient cohort with differences in iodine status, as well as studies on Tg changes after improving iodine status in pregnant women, are needed in order to corroborate these results.

No increase in renal iodine excretion during pregnancy: a telling comparison between pregnant women and their spouses

OBJECTIVE: Adequate dietary iodine intake is necessary for normal thyroid gland function at all times, and most particularly during pregnancy. Increased iodine loss is cited, among other factors, as responsible for the increased iodine demand in this period. Our aim was to compare renal iodine excretion between women during all three pregnancy trimesters with that of their spouses and thereby to estimate the iodine intake in an a large sample of pregnant women in urban areas in Greece. DESIGN: Four hundred twenty-four healthy pregnant women were included prospectively (residents of Athens n=218, residents of Patras n=206). The spouses of 177 of these women following the same diet were also studied. Determinations included serum FT4, TSH and aTPO and urinary iodine excretion (UIE). RESULTS: No difference was found either in median UIE throughout pregnancy or between the UIE of the pregnant women and their spouses during the trimesters. Throughout pregnancy, mild iodine deficiency was noted and was classified as mild in 60%, moderate in 30% and severe in 10% of the women studied. Users of iodized salt had significantly higher median UIE compared with non-users. Serum FT4 levels decreased and TSH increased as pregnancy progressed. CONCLUSIONS: Our study indicates that renal iodine excretion is not increased during pregnancy. This finding needs to be confirmed by further investigation in other populations with different iodine intakes. Thus, increased iodine requirements in pregnancy are possibly due to extra-renal causes. The population of pregnant women in Greek urban areas is mildly-and often moderately and severely-iodopenic and needs to be treated accordingly.

Female students receiving post-secondary education in Greece: the results of a collaborative human papillomavirus knowledge survey

OBJECTIVES Contrary to the optimistic forecasts, existing until 2008 and despite the incorporation of the vaccine into the Greek National Immunization Program, six years later, the percentage of HPV vaccination coverage in Greece remains disappointingly low. The aim of this extended study was to investigate the knowledge, behaviour and attitude of a representative sample of the initial target group; young female students of Greek higher education institutions to Pap cervical screening, biology of HPV infection and principles of HPV vaccination. STUDY DESIGN Cross-sectional study. METHODS One thousand two hundred ten (1210) questionnaires were completed by young female students aged 17-24 years. The survey questionnaire sought data relating to sociodemographic characteristics, health behaviour and knowledge about HPV, as well as vaccination status. RESULTS 79.6% of the sample reported at least one annual gynaecologic examination and 92.6% were familiar with the rationale of cervical screening; however only 52.9% had undergone a Pap smear. 69.7% reported adequate knowledge about HPV and 89.3% were aware of the possible course of HPV infection. Despite most (95.9%) were aware of vaccine availability, vaccinated students represented only 33.1%. According to the multivariate analysis, vaccination status was associated with university studies (OR 1.96; 95% CI: 1.19-3.20), parental area of expertise (OR 2.77; 95% CI: 1.18-6.53, OR 2.03; 95% CI: 1.05-3.94), and adequate knowledge of the reasons for which women should undergo regular cervical screening (OR 4.23; 85% CI: 1.55-11.55). Fear of side-effects and equivocal information were the main reasons of non-vaccination (52.2% and 33.1% respectively). Finally, the majority of unvaccinated individuals showed a positive attitude towards prospective HPV vaccination, providing they received well-documented advising. CONCLUSIONS Young women attending Greek higher education exhibit a good level of knowledge about HPV and its correlation with cervical cancer. These data highlight the need for further sensitization of the general population.

Necrotizing Fasciitis Complicating Pregnancy: A Case Report and Literature Review

Necrotizing fasciitis is a rare, life-threatening surgical infection in pregnancy with high rates of morbidity and mortality. A 15-year-old primigravid woman, at 28 weeks of gestation with no significant previous medical history, was admitted to our hospital complaining of severe left lower extremity pain and high fever the last 72 hours. During clinical examination, she had a swollen, erythematous and tender to palpation inflamed skin over the medial aspect of the upper thigh without any evidence of injury. Incision drainage was performed immediately and she received broad spectrum antibiotics. During initial laboratory examinations, diabetes mellitus was diagnosed. There was no clinical improvement over the following days. Magnetic resonance imaging (MRI) revealed subcutaneous tissue inflammation and edema of infected tissues confirming the disease entity. Multidisciplinary therapy with immediate aggressive surgical debridement of necrotic tissues, multiple antibiotics, and intensive care monitoring was performed successfully. The patients postoperative course was uncomplicated and skin defect was closed with split thickness skin grafting. Our case emphasized the potential immunosuppressive role of pregnancy state in conjunction with diabetes mellitus in the development of severe necrotizing soft tissue infections.

Systemic Sclerosis and Multiple Cancers of the Female Genital Tract: Prolonged Survival following Current Treatment Strategies

Background. Systemic sclerosis is a rare, chronic, multisystem, and autoimmune disease. There is an overall increased risk of malignancy in patients with systemic sclerosis. However, multiple cancers of the female genital tract in patients with SSc are a very rare event. Our aim is to present a case of SSc and multiple cancers of the female genital tract, with prolonged survival following current treatment strategies. Case. The patient, a 43-year-old nulliparous premenopausal Greek woman suffering from systemic sclerosis, presented with a history of abdominal pain and abnormal uterine bleeding. She underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy, total omentectomy, appendectomy, and pelvic lymph node dissection. The histopathology revealed synchronous primary cancers of the endometrium and left ovary. The final diagnosis was stage Ib endometrial cancer endometrioid type and stage IIIc ovarian cancer endometrioid type. She underwent postoperative adjuvant chemotherapy and remains well without evidence of disease 89 months after initial surgery. Conclusion. Although our patient was diagnosed at advanced stage disease, prolonged survival may be related with radical surgery and postoperative adjuvant chemotherapy according to current treatment strategies.
