Abstract
BACKGROUND Persistent infection with high-risk genotypes of human papillomavirus (HPV) is the main risk factor in the development of uterine cervical precancerous lesions and cervical cancer (CC), and cases of HPV-induced oropharyngeal squamous cell carcinoma (OPSCC) is increasing in the Western world. We investigated the association between HPV and p16 status and previous results of cervical examinations, including cytological and histological tests, in females with OPSCC. MATERIAL AND METHODS We included females diagnosed with an OPSCC in Eastern Denmark from 2000 to 2014. OPSCCs were assessed for p16-overexpression and HPV DNA PCR. History of cervical tests was obtained from the Danish Pathology Registry. The cytology and histological results were categorized in accordance with the 2014 Bethesda System (TBS) and WHO. Hence, we divide the cervical results into two groups. Group I were negative for intraepithelial lesion or malignancy and group II had epithelial cell abnormalities and subdivided after increasingly neoplastic severity from A-D. Chi2-tests and Fischer's exact tests were performed to compare the two groups. RESULTS A total of 417 women with OPSCC were identified; 203 with HPV-positive tumors (49%) of which cervical cytology or histology were available in 172 women (85%). Among these, 22 (13%) patients had a cervical history of ≥ IIC. A total of 171 out of 214 women in the HPV-negative group (80%) were examined with cytology and 17 had a history of ≥ IIC. No significant difference in diagnoses of (pre)cancerous lesions between the OPSCC HPV-positive and negative groups were observed (χ2 test p = .28, Fischer's exact test p = .29). CONCLUSION HPV status in oropharyngeal tumors was not correlated with a history of ≥ IIC in cervical examinations. The effect on cervical dysplasia may be masked by a higher incidence of smoking among the OPSCC HPV-negative group.

Abstract
OBJECTIVES To perform a neurophysiological follow-up at 48 or 60 months of age in children exposed prenatally to progesterone compared with a placebo and evaluate their medical histories up to 8 years of age. METHODS In this study, Danish participants of the PREDICT study, including 989 surviving children from 498 twin pregnancies, were followed-up. PREDICT was a placebo-controlled randomized clinical trial examining the effect of progesterone for prevention of preterm delivery in unselected twin pregnancies. Medical histories of the children were reviewed and neurophysiological development was evaluated by the parent-completed Ages and Stages Questionnaire (ASQ) at either 48 or 60 months after the estimated date of delivery. We used the method of generalized estimating equation to account for the correlation within twins. RESULTS A total of 492 children had been exposed prenatally to progesterone and 497 to placebo. There was no difference in the number of admissions to or length of stay in hospital between the treatment groups, and we found no overall difference in the rates of diagnoses made. However, the odds ratios (ORs) for a diagnosis concerning the heart was 1.66 (95% CI, 0.81-3.37), favoring placebo, among all children, 2.38 (95% CI, 1.07-5.30) in dichorionic twins and 8.19 (95% CI, 1.02-65.6) in all children when excluding diagnoses made at outpatient clinic visits. ASQ scores were available for 437 children (progesterone, n = 225; placebo, n = 212). Mean ASQ score was slightly higher in the progesterone group compared with the placebo group (P = 0.03). In dichorionic twins, the risk of having a low ASQ score (< 10(th) centile) was decreased in the progesterone group (OR, 0.34 (95% CI, 0.14-0.86)). CONCLUSION Second- and third-trimester exposure of the fetus to progesterone does not seem to have long-term harmful effects during childhood, but future studies should focus on cardiac disease in the child.

Abstract
BACKGROUND To elucidate how contraceptive attitudes among Danish-born and immigrant women influence the request of induced abortion. METHODS A case-control study, the case group comprising 1095 Danish-born women and 233 immigrant women requesting abortion, in comparison with a control group of 1295 pregnant women intending to give birth. The analysis used hospital-based questionnaire interviews. RESULTS Lack of contraceptive knowledge and experience of contraceptive problems were associated with the choice of abortion. This association was most pronounced among immigrant women, where women lacking knowledge had a 6-fold increased odds ratio (OR) and women having experienced problems a 5-fold increased OR for requesting abortion. Further, in this group of women, a partner's negative attitude towards contraception was associated with an 8-fold increased OR for requesting abortion. Contraceptive failure was prevalent; 21% of the women who did not plan to become pregnant but intended to give birth had experienced contraceptive failure. The same applied, respectively, for 45% of the Danish-born women and 36% of immigrant women, who requested abortion. Women who had experienced contraceptive failure were significantly more likely to request abortion. CONCLUSIONS Immigrant women seem to have more difficulties in using contraception than Danish-born women. To address this problem, there is a need for culturally sensitive information campaigns targeting this heterogonous group of women.

Abstract
OBJECTIVE The aim of this study was to determine the ovarian volume by transvaginal ultrasonography in a gynecologically healthy population of women using no contraception, using intrauterine contraceptive device, or using oral contraceptive. MATERIALS AND METHOD The study had a cross-sectional design. The ovaries of 428 women aged 1445 who contacted the family planning clinic in the county of Funen were examined. Most of the statistical analyses were carried out using standard techniques. However polynominal regression analysis was used to model ovarian volumes as a function of the day of cycle. RESULTS No differences between the volumes of the right and the left ovary were found in any of the groups. Significant differences were found between the ovarian volumes of the three groups. The ovarian volumes were found to be largest in women using intrauterine contraceptive device, lesser in women using no contraception and smallest in women using oral contraception. A significant difference was found of the ovarian volumes throughout the menstrual cycle in women who were not using oral contraception. The ovarian volumes did not change throughout the menstrual cycle in women using oral contraception. In women not using oral contraception the largest ovary increased in volume from the start of the cycle to day 19, thereafter the volume declined. No evidence of any change of volume over the menstrual cycle was found in the smallest ovary and, for women using oral contraception, both ovaries. There was no correlation between age, height, weight, parity, and ovarian volume in any of the groups. CONCLUSION The ovarian volumes, in gynecologically healthy women using intrauterine contraceptive device, are larger than in women using no contraception. It appears that oral contraception reduces the volumes of both ovaries in all phases of the menstrual cycle to equal levels.

Abstract
Transvaginal ultrasonography has an excellent patient acceptability and generally gives a more detailed picture of pelvic structures compared to what can be achieved by the transabdominal route, mainly because of the higher sound-frequency of the probes (5-7.5 MHz). On the basis of recent literature, a review is given concerning major clinical applications. The method has a firmly established role in diagnosing complications during early pregnancy as well as in modern infertility treatment. Recent advances have been obtained in several other fields of obstetrics and gynaecology, but further studies are still needed. Color Doppler mapping and characterization of flow by Doppler spectral analysis show great potentials in the hands of the gynaecological oncologist.

Abstract
The morphology of the inner ear in rheas was examined by light and electron microscopy. The shape is typically bird-like with very long semicircular canals. The anterior and posterior cristae have small septa cruciata. The vestibular sensory epithelia contain two main types of hair cell innervation; bouton-innervated hair cells and calyceal hair cells characterized by a surrounding nerve calyx. The utricular macula has a single zone of calyceal hair cells, while all other previously examined birds, except the mute swan, have 2 zones. The height of the tallest sensory hairs of the cristae is 20-30 microns. In the utricular and lagenar macula, the hairs are 5-7 microns in the striola and 10-20 microns in the main parts of the sense organs. Along the edges of the maculae the longest hairs may reach 20-30 microns. The number of stereovilli on mature vestibular hair cells is 40-60. The sensory hairs of the hearing organ, the basilar papilla, are generally shorter but more numerous than the vestibular sensory hairs. In the proximal end, the tallest of the 175-200 stereovilli are 2.8-3.7 microns; in the distal end of the papilla, the number of stereovilli decrease to 65-100, and their height increases gradually to 7.3-8.7 microns. The neural sensory hairs are generally taller than those of the abneural side.
