Distribution of human papillomavirus genotypes in women with high-grade cervical intraepithelial lesions and cervical carcinoma and analysis of human papillomavirus-16 genomic variants.

AIM: To analyze the distribution of high-risk human papillomavirus (HR-HPV) genotypes and the diversity of HPV-16 genomic variants in Croatian women with high-grade squamous intraepithelial lesions (HSIL) and cervical carcinoma. METHODS: Tissue biopsy specimens were obtained from 324 women with histopathologically confirmed HSIL or cervical carcinoma, 5 women with low-grade SIL, and 49 women with negative histopathology. HR-HPV DNA was detected with Ampliquality HPV-type nucleic-acid hybridization assay, which identifies 29 different HPV genotypes. HPV-16 genomic variants were analyzed by an in-house sequencing. RESULTS: The most common HPV type in women with HSIL was HPV-16, detected in 127/219 (57.9%) specimens. HPV-16 was also the dominant type in squamous cell cervical carcinoma (46/69 or 66.7%) and in adenocarcinoma (18/36 or 50.0%). Out of 378 patients, 360 had HR-HPV (282 single infections and 79 multiple infections), 3 (0.8%) patients had low-risk HPV, and 15 (4%) tested negative. HPV-16 variants were determined in 130 HPV-16 positive specimens, including 74 HSIL and 46 carcinoma specimens. In HSIL specimens, 41 distinct variants were found, 98.6% belonging to the European branch and 1.4% belonging to the African branch. In cervical carcinoma specimens, 95% isolates grouped in 41 variants belonging to the European branch, one isolate (2.5%) belonged to the North American, and one (2.5%) to the Asian-American branch. CONCLUSION: HPV-16, mainly belonging to the European branch, was the most frequent HPV genotype in women from Croatia with histologically confirmed HSIL and cervical cancer.

Electrocoagulation versus suture after laparoscopic stripping of ovarian endometriomas assessed by antral follicle count: preliminary results of randomized clinical trial.

PURPOSE: The assessment of ovarian reserve by antral follicle count (AFC) following electrocoagulation versus suture after laparoscopic stripping of ovarian endometriomas. METHODS: Forty-five patients between 18 and 35 years, with unilateral endometriomas were randomly analyzed. Laparoscopic cystectomy was performed by the stripping method. Ovarian hemostasis was obtained either by suturing (group A, n = 23) or by bipolar electrocoagulation (group B, n = 22). AFC was performed by ultrasound on the third day of the three postoperative menstrual cycles. The sum of AFC was compared between sutured (A1) and electrocoagulated (B1) ovaries, as well as between intact ovaries of both groups (A0: intact ovaries in sutured group, B0: intact ovaries in electrocoagulated group). RESULTS: The median of AFC was significantly lower in operated ovaries than in intact ovaries in both groups of patients, regardless of suturing [A1 median: 12 (range 9-19) vs. A0 median: 21.0 (range 15-27), p < 0.05] or electrocoagulation [B1: 5.0 (2-10) vs. B0: 18.5 (8-29), p < 0.05]. The median AFC was significantly higher in sutured ovaries than in electrocoagulated ovaries [A1: 12 (9-19) vs. B1: 5.0 (2-10), p < 0.05]. CONCLUSION: Our preliminary data show that operation on ovarian endometriomas could reduce ovarian reserve. The AFC value suggests that the ovarian reserve was less reduced in sutured ovaries than in those electrocoagulated. Suturing as a method of hemostasis could be a better choice after stripping ovarian endometriomas.

Validation of the Croatian Version of the 8-Item Overactive Bladder Questionnaire (OAB-V8).

OBJECTIVES: The present study was conducted with the aim to translate, adapt, and validate the 8-item Overactive Bladder Questionnaire (OAB-V8) in Croatia. METHODS: This study included a total of 58 female patients with OAB and 66 healthy women. The translation to Croatian followed standardized procedure. All eligible participants completed OAB-V8 at inclusion and 2 weeks after to assess test-retest reliability. Cronbach α coefficient was calculated to assess internal consistency. RESULTS: Our study demonstrated high internal consistency for all items at both visits (Cronbach α between 0.799 and 0.847), with stable internal consistency reliability across items during the 2-week period. However, the exception is the item "waking up at night to urinate," which significantly changed during the 2-week period. Intraclass correlation for OAB-V8 items ranged from 0.810 to 1.0, with Spearman correlations greater than 0.9 for all items (P < 0.01). There were strong significant correlations between frequency of urination during daytime and uncomfortable and sudden urge to urinate, and between nocturia and waking up at night. Discriminative validity showed statistically significant score differences between patients and the control group. CONCLUSIONS: The Croatian version of the OAB-V8 was successfully translated, adapted, and validated so the questionnaire is now ready for use as a reliable tool for initial screening and assessing patients with OAB in everyday Croatian clinical practice.

Cervical cancer as a public health issue--what next?

Cervical cancer is the second most common cancer in women worldwide. There are about 60,000 newly detected cases and 30,000 deaths annually in Europe, with the highest incidence reported from Eastern Europe countries. According to data from the National Institute of Public Health, in Croatia the incidence of cervical cancer was 14.9/100,000 in 2006, ranking eighth most common malignancy in women. Croatia has a lower incidence of the disease compared to many countries of Central and Southeast Europe. A large study carried out in 1995 by the International Agency for Research on Cancer, which included cervical cancer material collected from 22 countries all over the world revealed HPV genome in 99.7% of cases. Efficient methods of cervical cancer detection and screening methods for identification of precancerous lesions (conventional Pap smear) are available. Cervical cancer prevention programs should include education (of health care providers and women), stressing the benefits of screening, the age of the peak cervical cancer incidence, and the signs and symptoms of precancerous lesions and invasive disease. The aim of screening actions is to detect precancerous lesions that may lead to cancer if left untreated. Screening can only be effective if there is a well-organized system of follow up, diagnosis and treatment. Cervical cytology, or Papanicolaou (Pap) testing, has for decades been a cornerstone of cervical cancer screening. According to recent guidelines issued by the World Health Organization Regional Office for Europe, the primary task of the public health system is the introduction of secondary prevention through properly organized screening programs. Launching the national immunization program is only possible in the countries with well-organized secondary prevention programs and in those that can afford it.
