Comparison of nerve content in removed parametrial tissue after classic radical hysterectomy and nerve-sparing radical hysterectomy--histologic evaluation.

PURPOSE OF INVESTIGATION: The aim of this study was to find whether nerve-sparing radical hysterectomy resulted in a lower amount of nerves in the removed parametrial tissue. METHODS: Histological specimens from nerve-sparing radical hysterectomy (28 cases) were compared with those obtained after classic radical hysterectomy (26 cases). Width of the parametria and vaginal cuff were measured. Using a point counting technique, nerve areal density was determined in cross sections of resected parametria at 0.5 cm (A), 1 cm (B), 1.5 cm (C) from the cervix. RESULTS: The width of the resected parametria was smaller in the study group (right side p < 0.013; left side; p < 0.011). The nerve areal density in the lateral part of the right parametrium was lower in the study group (p < 0.01) (Student's t-test). CCONCLUSION: Modified radical hysterectomy is less radical and is nerve-sparing.

Choroidal melanoma metastasized to the ovary: case report and review of the literature.

BACKGROUND: Malignant melanoma metastases to the female genital tract in only 2.5% of cases. Melanoma is characterized by clinical variability and unpredictable biological behavior with long remissions and relapses that develop rapidly. CASE AND REVIEW: A 57-year-old woman was admitted for hypogastric pain and weight loss. She had presented enucleation of the right eye six years before for malignant choroid melanoma. Gynaecological examination revealed enlarged ovaries. Bilateral salpingo-oophorectomy, hysterectomy, and omentectomy were performed. Final pathology diagnosed a choroidal metastatic melanoma (CMM). The patient died seven months later. Only seven cases of CMM have been reported in the literature. Patients affected by CMM ranged in age from 38 to 83 years (median 51.2 years), the time to relapse ranged from 3-25 years (median 51.2 years), the size of the cysts ranged from 4-17 cm (median 9.7 cm) and the survival period ranged from 2-14 months (median 8.1 months). CONCLUSION: Malignant melanoma is misdiagnosed because of lack of discriminatory symptoms, increased tumor markers, characteristic imaging findings and the capacity to mimic other tumors. Today CMM still represents a challenge for gynecologic oncologists.

Amelanotic malignant melanoma of the uterine cervix with ten-year follow-up.

BACKGROUND: Malignant melanoma (MM) accounts for 3% of cancers that affect women and results in less than 1% of cancer deaths. It is characterized by clinical variability and unpredictable biological behavior. Fewer than ten cases of amelanotic MM (AMM) have been reported in literature. CASE: A 61-year-old woman was admitted for vaginal spotting. A huge, soft cervix with an exophytic lesion was biopsied. A clear cell carcinoma, FIGO Stage IB1, was diagnosed and radically treated. The final pathology showed an AMM of the cervix positive for PAS and HMB 45. The patient is clinically free of disease ten years postoperatively. CONCLUSION: Malignant melanoma of the cervix is often misdiagnosed because of non discriminatory features and the capacity to mimic other tumors. Malignant melanoma of the cervix needs to be diagnosed as quickly as possible because a timely therapy and a long and careful follow-up might result in better survival.

Localized expression of an anti-TNF single-chain antibody prevents development of collagen-induced arthritis.

Although systemic administration of neutralizing anti-TNF antibodies has been used successfully in treating rheumatoid arthritis, there is a potential for side effects. We transduced a collagen reactive T-cell hybridoma with tissue-specific homing properties to assess therapeutic effects of local delivery to inflamed joints of anti-TNF single-chain antibodies (scFv) by adoptive cellular gene therapy. Cell culture medium conditioned with 1 x 10(6) scFv producer cells/ml had TNF neutralizing capacity in vitro equivalent to 50 ng/ml anti-TNF monoclonal antibody. Adding a kappa chain constant domain to the basic scFv (construct TN3-Ckappa) gave increased in vitro stability and in vivo therapeutic effect. TN3-Ckappa blocked development of collagen-induced arthritis in DBA/1LacJ mice for >60 days. Transgene expression was detected in the paws but not the spleen of treated animals for up to 55 days postinjection. No significant variations in cell proliferation or cytokine secretion were found in splenocytes or peripheral lymphocytes. IL-6 expression was blocked in the diseased paws of mice in the scFv treatment groups compared to controls. In conclusion, we have shown that local expression of an anti-inflammatory agent blocks disease development without causing demonstrable systemic immune function changes. This is encouraging for the potential development of safe adoptive cellular therapies to treat autoimmunity.

[Actinomyces-like organisms in users of intrauterine contraception]. / Aktinomicetama slicni organizmi u korisnica intrauterine kontracepcije.

Actinomyces-like organisms (ALO) were found in 6.9% of cervical smears in 2133 IUD users. The chance of having co-infection with Trichomonas vaginalis was 2.7 times higher in women with ALO than in ALO negative women. The proportion of IUD users with ALO in cervical smears increased with the duration of the IUD use. A total of 108 IUD users with ALO were compared with the same number of IUD users without ALO in cervical smears. The women in the two groups were matched for the duration of the IUD use. During the IUD use the women with ALO had PID and vaginitis significantly more frequently than ALO negative women. No difference was found regarding the type of the IUD used in women with ALO in cervical smears compared to controls.
