Cervical intraepithelial neoplasia in women with transformation zone type 3: cervical biopsy versus large loop excision.

OBJECTIVE: To compare the proportion of cervical intraepithelial neoplasia grade 2 or higher (CIN2+) in cervical biopsies with that in large loop excision of the transformation zone (LLETZ) specimens in women aged ≥45 years with transformation zone type 3 (TZ3). DESIGN: Multicentre cross-sectional study. SETTING: Three colposcopy clinics in the Central Denmark Region. POPULATION: Women aged ≥45 years referred to colposcopy as a result of a positive human papillomavirus (HPV) test and/or abnormal cytology and with TZ3 at colposcopy. METHODS: Women had multiple biopsies taken and an LLETZ was performed. MAIN OUTCOME MEASURES: Histologically confirmed CIN2+ in biopsies compared with that in LLETZ specimens. RESULTS: Of 166 eligible women at colposcopy, 102 women with paired data from biopsies and LLETZ specimens were included for final analysis. The median age was 67.7 years (IQR 62.6-70.4 years), and most were postmenopausal (94.1%) and had undergone HPV-based screening (81.3%). The CIN2+ detection rate was significantly higher in LLETZ specimens than in biopsies (32.4% vs 14.7%, difference 17.7%, 95% CI 6.3-29.0%), resulting in more than half of CIN2+ cases being missed in biopsies (54.5%, 95% CI 36.4-71.9%). The overall agreement between biopsies and LLETZ was 82.4% (95% CI 73.6-89.2%). CONCLUSIONS: CIN2+ detection is underestimated in women aged ≥45 years with TZ3 if detection relies on the results of biopsies alone. To reduce the risk of underdiagnosis and overtreatment, future studies should explore the use of new biomarkers for risk stratification to improve discrimination between women at increased risk of CIN2+ who need to undergo LLETZ and women who may undergo follow-up.

Assessment of Zinc Nanoparticle Effect and Expression of Zinc Uptake Gene in Drug Resistance Acinetobacter baumannii Strain FMHLN5.

BACKGROUND: Drug resistance bacteria pose an increasing threat to public health. Antimicrobial agents often lack efficacy toward recently developed drug resistance bacteria. Nanoparticles are one of the most effective treatment agents. The aim of this study was to evaluate the expression of zinc uptake regulator gene with zinc nanoparticle stress in drug resistant Acinetobacter baumannii strain FMHLN5. METHODS: The antimicrobial susceptibility technique was evaluated through disk diffusion methods. ZnO nanoparticles (ZnO-NPs) were synthesized using an acetate precursor-based sol-gel route. In vitro, the FMHLN5 strain susceptibility to ZnO-NPs has been tested by the agar wells diffusion method, using varying sizes (20 to 520 nm) of ZnO NPs. The purities and sizes of Nano-ZnO was determined by X-ray diffraction (XRD) and scanning electron microscope (SEM). The expression of the zinc-uptake gene was investigated through the qRT-PCR technique. RESULTS: The results revealed that the ZnO NPs against clinical FMHLN5 strain were useful at different sizes. The expression of the zinc-uptake gene was observed. CONCLUSIONS: The effect of ZnO NPs was strong, as reflected by inhibition zones at different sizes. Thus, ZnO NPs potentially induced bactericidal effect for fighting FMHLN5 strain.

Nonspecific Symptoms in a Rare Case of Urethral Adenocarcinoma in a 58-Year-Old Female.

Cancer of the urethra is very rare with an age-adjusted incidence of only 0.6 per million women in Europe. The etiology is multifactorial and the incidence increases with age, with the highest rates in patients 75 years or older. We herein describe a 58-year-old woman referred to our unit due to pollakisuria and repeated lower urinary tract infections. The gynecological examination revealed a suspect area in the anterior wall of vagina. Subsequently, ultrasound examination, MRI, and PET-CT scan followed by vaginal biopsies revealed a urethral adenocarcinoma.

Endometrial Stromal Nodule: A Rarity and a Pathological Challenge.

Endometrial stromal tumors are rare, and endometrial stromal nodule is the least common. In the region of Middle Jutland, Denmark, only two cases are reported since 1995. The nodules are benign; nevertheless, hysterectomy is the treatment of choice. Tumor margins are required for diagnosis and essential to differentiate it from an invasive stromal sarcoma whose prognosis is very different. We report a rare case of a 38-year-old woman, with presurgical diagnosis of a uterine tumor/polyp. She presented with nausea and changes in bleeding pattern and initially had a transcervical polyp resection performed. Histopathological examination showed the presence of an endometrial stromal tumor with unclear margins, and an invasive malignant endometrial sarcoma could not be excluded. Pathological examination revealed an endometrial stromal nodule with invasion, not exceeding three mm. Endometrial stromal tumors are interesting due to their rare existence and difficulties in establishing a histological diagnosis. Although endometrial stromal nodules are benign entities, they must be differentiated from the other invasive malignant stromal tumors, which may change the final prognosis. No preoperative diagnostic tools are at hand, and benign as well as malignant tumors are treated with hysterectomy.

Paraurethral leiomyoma in a postmenopausal woman: first European case.

Leiomyomas are benign tumors extending from smooth muscle cells and only few cases of paraurethral leiomyomas have been described in the literature. They are often seen in the reproductive age and around 50% of the cases are asymptomatic. We describe a 59-year-old woman with a solid mobile tumor below the symphysis revealed at a gynecological examination. Transvaginal ultrasound and MRI confirmed the tumor and excision of the paraurethral tumor was carried out. The histological examination showed a benign paraurethral leiomyoma. The postoperative period was characterized by urethral pain as well as vaginal leakage of urine.

[The diagnostic value of human chorionic gonadotrophin ratio compared to single measurements of S-human chorionic gonadotrophin on the outcome of pregnancy of unknown location].

Pregnancy of unknown location is defined by a positive pregnancy test, without visualizing of the intrauterine or extrauterine pregnancy by transvaginal sonography. We present the advantages of using human chorionic gonadotrophin (hCG) ratio instead of single measurements of S-hCG for predicting the outcomes of pregnancies of unknown location.

[Reasons for removal of intrauterine devices among women in general practice]. / Årsager til fjernelse af spiral hos kvinder i almen praksis.

Prolonged bleeding or spotting and pain are the most common reasons for women to request early removal of intrauterine device (IUD). We wanted to investigate which parameters influenced the removal of IUDs among women in general practice and to see if there was a difference between copper-releasing IUDs and levonorgestrel-releasing IUDs. In general the women were satisfied with both types of IUDs. More women with copper-releasing IUDs had an early removal because of complaints than women with levonorgestrel-releasing IUDs.

Predictive value of serum human chorionic gonadotropin ratio, progesterone and inhibin A for expectant management of early pregnancies of unknown location.

OBJECTIVE: To evaluate serum human chorionic gonadotropin (hCG) ratio, progesterone and inhibin A as single parameters and in combination for the prediction of spontaneous resolution of pregnancies of unknown location (PUL). STUDY DESIGN: Prospective observational study of 105 consecutive patients with a diagnosis of PUL. Serum levels of hCG, progesterone and inhibin A were determined at the first visit and after 2 days. Patients were followed clinically until a final diagnosis of spontaneously resolving PUL, viable or non-viable intrauterine pregnancy, or ectopic pregnancy with need of laparoscopic intervention had been reached. Different combinations of hCG ratio (hCG at 48 h/hCG at 0 h), s-progesterone and s-inhibin A were investigated to find the best predictor for successful expectant management. RESULTS: The final pregnancy outcomes were: 52 spontaneously resolving PUL (49.5%), 37 viable intrauterine pregnancies (35.2%), 8 non-viable intrauterine pregnancies (7.6%), 7 ectopic pregnancies (6.7%), and one molar pregnancy (1.0%). An hCG ratio<0.80 predicted spontaneously resolving PUL with positive and negative predictive values (PPV and NPV), sensitivity, and specificity of 0.98, 0.78, 0.72, and 0.99, respectively. In patients with hCG ratio ≥ 0.80, a combination of s-progesterone < 20 nmol/l and s-inhibin A < 30 pg/ml predicted spontaneously resolving PUL with PPV, NPV, sensitivity and specificity of 0.92, 0.96, 0.85, and 0.98 respectively. CONCLUSION: Our results suggest that patients with PUL and hCG ratio < 0.80 display a high probability of spontaneously resolving PUL with minimum need of follow-up. In cases of hCG ratio ≥ 0.80, a combination of s-progesterone < 20 nmol/l and s-inhibin A < 30 pg/ml, may be a reliable predictor of spontaneously resolving PUL. The safety of this approach should be tested in large prospective studies.

[Ultrasonically verified vesicouterine fistula]. / Ultralydverificeret vesikouterin fistel.

We report a case of a vesicouterine fistula occurring after a Caesarean section. There was a noticeable delay in recognizing the fistula, which was, however, clearly visible on a vaginal ultrasound scanning. When urinary incontinence is developed after gynaecologic or obstetric surgery, a fistula must be suspected.
