BackgroundThe purpose of this work was to investigate whether clinical cytology could be useful in the preoperative diagnosis of pelvic actinomycosis.MethodsThis study involved the prospective collection of samples derived from the endometrium and the uterine cervix, and retrospective data analysis. Nine patients with clinically diagnosed pelvic actinomycosis were enrolled. The clinical and hematological characteristics of patients were recorded, and detection of actinomyces was performed by cytology, pathology, and bacteriological culture of samples and by imprint intrauterine contraceptive device (IUD) cytology.ResultsThe detection rate of actinomyces was 77.7% by combined cervical and endometrial cytology, 50.0% by pathology, and 11.1% by bacterial culture.ConclusionThe higher detection rate of actinomyces by cytology than by pathology or bacteriology suggests that careful cytological examination may be clinically useful in the preoperative diagnosis of pelvic actinomycosis.

Conservative laparoscopic surgery is a safe procedure to preserve ovarian function in women with adnexal torsion. Careful attention and measures should be considered during follow-up management with the fact in mind that adhesion is a common occurrence and even tubal occlusion may occur in some cases.

Fibroblast growth factor receptor 1 (FGFR1) is one of the causative genes for Kallmann syndrome (KS), which is characterized by isolated hypogonadotropic hypogonadism with anosmia/hyposmia. The third immunoglobulin-like domain (D3) of FGFR1 has the isoforms FGFR1-IIIb and FGFR1-IIIc, which are generated by alternative splicing of exons 8A and 8B, respectively. To date, the only mutations to have been identified in D3 of FGFR1 are in exon 8B. We performed mutation analysis of FGFR1 in a 23-year-old female patient with KS and found a missense mutation (c.1072C>T) in exon 8A of FGFR1. The c.1072C>T mutation was not detected in her family members or in 220 normal Japanese and 100 Caucasian female controls. No mutation in other KS genes, KS 1, prokineticin-2, prokineticin receptor-2 and FGF-8 was detected in the affected patient or in her family members. Therefore, this is the first case of KS carrying a de novo missense mutation in FGFR1 exon 8A, suggesting that isoform FGFR1-IIIb, as well as isoform FGFR1-IIIc, plays a crucial role in the pathogenesis of KS.

The aim of this study was to investigate the relationship between viral load in single human papillomavirus (HPV) 16 or 52 persistent infection and the progression of later cytopathological findings in the uterine cervix. Cervical cytology and HPV genotyping tests were repeated within 3-6 months in 305 women with oncogenic HPV. Twenty-four cases of single HPV 52 persistent infection and 24 cases of single HPV 16 persistent infection were identified. Cases with later cytopathological findings showing progression were defined as the progression group, while those with no change or regression were the non-progression group. Relative HPV DNA loads were determined by quantitative real-time polymerase chain reaction and expressed relative to human albumin (ALB) DNA. Differences between the two groups were evaluated. The median relative HPV 52 DNA load was 2.211 in the progression group and 0.022 in the non-progression group (Mann-Whitney U-test, P = 0.003). The median relative HPV 16 DNA load was 4.206 in the progression group and 0.103 in the non-progression group (P = 0.001). HPV 52 and 16 DNA loads assessed by quantitative real-time methods may be useful short-term markers for identifying women at high risk for progression of cervical cytological pathology.
