Posterior leukoencephalopathy following cisplatin,bleomycin and vinblastine therapy for germ cell tumor of the ovary

A 31-year-old female developed multiple episodes of grand mal seizures after combination chemotherapy with cisplatin, vinblastine and bleomycin for germ cell ovarian cancer stage Ic. The clinicoradiologic features in this patient were consistent with posterior leukoencephalopathy, which is a rare complication of chemotherapy. Seizures were controlled by the anticonvulsive agent Dilantin (Pfizer, Khet Klongtoey, Bangkok) and she returned home without any permanent neurologic deficits. Follow-up magnetic resonance imaging 2 weeks later showed complete resolution of the abnormalities. This syndrome has been previously reported following cisplatin-based chemotherapy. Physicians should remain alert to the potential hazards of chemotherapy to the central nervous system. Risks and benefits should be seriously considered before starting treatment.     

Knowledge,Attitudes and Behavior of Bangkok Metropolitan Women Regarding Cervical Cancer Screening

Purpose: To assess knowledge, attitudes and cervical cancer screening behavior of Bangkok Metropolitan women. Materials and Methods: Thai women, aged 25-to-65 years old, having lived in Bangkok for 5 years or more were invited to participate in the study. After signing informed consent, all women were asked to complete a self-questionnaire (Thai language) with literate assistance if needed. The questionnaire was divided into 3 parts: (I) demographic data; (II) knowledge about cervical cancer screening; and (III) behavior and attitudes, towards cervical cancer screening. Adequate screening was defined as women who had two cervical cancer screening tests except women aged 25-30 years who may have only one screening, and the last screen was within 5 year or had had regular screening. Results: Of 4,339 women, there were 1,857 (42.8%) with adequate screening and 2,482 (57.2%) with inadequate screening. Significant factors associated with inadequate screening included age < 45 years, pre-menopausal status, family monthly income no knowledge, lack of awareness and poor attitudes. Three major reasons provided by women for inadequate screening were no symptoms (54.4%), fear of pain (33.2%), and embarrassment (34.6%). Conclusions: Personal features, knowledge, and attitudes influence screening behavior of Bangkok Metropolitan women. The three most common reasons of women for not undergoinging screening are no symptoms, fear of pain, and embarrassment. These factors should be the focus of attention to improve coverage of cervical cancer screening in Bangkok.     

Paclitaxel and carboplatin for large cell neuroendocrine carcinoma of the uterine cervix

The prognosis of large cell neuroendocrine carcinoma (LCNEC) of the uterine cervix is generally poor despite multimodality of treatments. We report a case of advanced stage cervical LCNEC that showed definite response to paclitaxel/carboplatin, resulting in years of survival. The patient was referred to our institution after undergoing a simple hysterectomy with bilateral salpingo-oophorectomy in her local hospital because of a ruptured metastatic ovarian mass. She declined pelvic radiation treatment, so adjuvant chemotherapy (six cycles of paclitaxel/carboplatin) was given for the residual pelvic nodal diseases. Clinical complete remission was obtained, with a disease-free period of 19 months. Systemic recurrent diseases also showed partial response to the same drug regimen for months with only minimal toxicity. However, she subsequently had progressive diseases in the liver and brain and finally died at 44 months after primary diagnosis and 19 months after recurrent diseases.     

Knowledge and Attitudes of Bangkok Metropolitan Women towards HPV and Self-Sampled HPV Testing

Background: To evaluate knowledge of Bangkok women regarding HPV and self-sampled HPV testing, and their attitudes towards testing. Materials and Methods: Thai women who had lived in Bangkok for more than 5 years, aged 25-to-65 years old, were invited to join the study. Participating women were asked to a complete self-questionnaire (Thai language), with literate assistance as needed. The questionnaire was divided into 3 parts: (I) demographic data, (II) knowledge and (III) attitudes towards self-sampled HPV testing. Before proceeding to Part III of the questionnaire, a 15-minute educational video of self-sampled HPV testing was presented to all participants. Results: Among 2,810 women who answered the questionnaires, 33.7% reported that they did not know about HPV. The characteristic features of these women were older age ( > 50 years), lower income ( < 600 USD/month), unemployed status, and non-attendees at cervical cancer screening. Only small numbers of women (4.6%) responded that they had heard about self-sampled HPV testing. After having information, 59.6% would not use the self-sampled HPV testing as a method of cervical cancer screening (non-acceptance). Factors significantly associated with the non-acceptance were older age, lower income, having no knowledge about HPV or self-collected HPV testing, a perception that the testing was unreliable and a concern that they might not be able to perform it correctly. Conclusions: Nearly half and almost all Bangkok women did not know about HPV and self-sampled HPV testing, respectively. Approximately 60% of Bangkok women refused to do the self-sampled HPV testing. Significant negative attitudes were concerns that the testing would be unreliable and a lack of confidence to perform the procedure correctly. Education about HPV and self-sampled HPV testing, ease of the procedure, or the testing models may increase rate of acceptability or positive attitudes.     

Visual inspection with acetic acid for detection of high grade lesion in atypical squamous cells and low grade squamous intraepithelial lesions from cervical Pap smear

Objective

To evaluate the value of visual inspection with acetic acid (VIA) test to detect high grade lesion in women with atypical squamous cells or low grade squamous intraepithelial lesions cervical cytology.

Methods

Women with atypical squamous cells or low grade squamous intraepithelial lesions who were scheduled to undergo colposcopy at Vajira Hospital and met inclusion criteria were included. All participants underwent VIA test prior to usual steps of colposcopy. The VIA results were interpreted as positive or negative using the criteria by the International Agency for Cancer Research. The standard colposcopic examination and appropriate investigations for cervical pathology were then continued. The diagnostic values of VIA test including sensitivity, specificity, positive predictive value, and negative predictive value were determined using high grade lesion including cervical intraepithelial neoplasia 2-3 and squamous cell carcinoma as a threshold.

Results

Total of 106 women was included. The VIA test was positive in 33 women (31.1%) and negative in 73 women (68.9%). Among the women with VIA test positive, 14 had high grade lesion (42.4%) while 19 had no significant lesions. Only 2/73 (2.7%) cases with negative VIA test had high grade lesion (both had cervical intraepithelial neoplasia 2). The sensitivity, specificity, positive predictive value and negative predictive value with 95% confidence interval were 87.5% (81.2 to 93.8%), 78.8% (71.1 to 86.7%), 42.4% (33.0 to 51.8%), and 97.2% (94.2 to 1.0%) respectively.

Conclusion

VIA as the intermediate test in atypical squamous cells and low grade squamous intraepithelial lesions cytology may reduce the necessity to refer some women for colposcopy.     

Resurfacing the degloved thumb up to the interphalangeal joint level with twin extended neurovascular island flaps

We report a method of resurfacing the degloved thumb from the base of the thumb up to the interphalangeal joint level using two neurovascular island flaps from the adjacent sides of the long and the ring fingers, nourished by the third common neurovascular pedicle. This twin flap was used successfully in seven patients. The reconstruction gave adequate static two-point discrimination of 10mm at 6 weeks without complaints of neuroma pain, painful scars or cold intolerance.     

Prevalence and Associated Factors of Abnormal Cervical Cytology and HighRisk HPV DNA among Bangkok Metropolitan Women

Background: Many strategies are required for cervical cancer reduction eg provision of education cautious sexual behavior, HPV vaccination, and early detection of preinvasive cervical lesions and invasive cancer Basic health data for cervical cytology/ HPV DNA and associated factors are important to make an appropriate policy to fight against cervical cancer Aims: To assess the prevalence of abnormal cervical cytology and/or HPV DNA and associated factors, including sexual behavior, among Bangkok Metropolitan women Materials and Methods: Thai women, aged 25to65 years old, had lived in Bangkok for 5 years were invited into the study Liquidbased cervical cytology and HPV DNA tests were performed Personal data were collected Main Outcomes Measures: Rates of abnormal cytology and/ or highrisk HPV (HRHPV) and factors associated with abnormal test(s) were studied Results: Abnormal cytology and positive HRHPV were found in 63% (279/4442 women) and 67% (295/4428), respectively The most common abnormal cytology was ASCUS (35%) while the most common HRHPV genotype was HPV 16 (14%) followed by HPV 52 (10%), HPV 58 (09%), and HPV 18 and HPV 51 at equal frequency (07%) Both tests were abnormal in 16% (71/4428 women) Rates of HRHPV detection were directly associated with severity of abnormal cytology: 54% among normal cytology and 130%, 308%, 400%, 395%, 563% and 1000% among ASCUS, ASCH, AGCNOS, LSIL, HSIL, and SCC, respectively Some 5% of women who had no HRHPV had abnormal cytology, in which 03% had HSIL Factors associated with abnormal cytology or HRHPV were: age 40 years, education lower than (for cytology) or higher than bachelor for HRHPV), history of sexual intercourse, and sexual partners 2 Conclusions: Rates for abnormal cytology and HRHPV detection were 63% and 67% HRHPV detection was directly associated with severity of abnormal cytology Significant associated factors were age 40 years, lower education, history of sexual intercourse, and sexual partners 2     

Glomus tumors of the fingers:Expression of vascular endothelial growth factor

Glomus tumors are uncommon,benign,small neuro-vascular neoplasms derived from glomus bodies in the reticular dermis. Glomus bodies are found throughout the body to regulate body temperature and skin circulation; however,they are concentrated in the fingers and the sole of the foot. The typical presentation is a solitary nodule in the subungual or periungual area of the distal phalanx. The primary treatment of choice is surgical removal. We investigated expression of vascular endothelial growth factor(VEGF) using immunohistochemistry in glomus tumors of the fingers. All five glomus tumor samples were positive for VEGF expression. VEGF immunoreactivity was largely localized to the cytoplasm of tumor cells,suggesting a contribution of VEGF to the vascularization of glomus tumors.     

Uterine Sarcoma: Clinical Presentation,Treatment and Survival Outcomes in Thailand

Background: Uterine sarcoma is a group of rare gynecologic tumors with various natures, and different lines of treatment. Most have a poor treatment outcome. This study targeted clinical characteristics, treatment, overall survival (OS), progression-free survival (PFS), and prognostic factors in uterine sarcoma patients in one tertiary center for cancer care. Materials and Methods: Uterine sarcoma patients who were treated at the Department of Obstetrics and Gynecology, Faculty of Medicine Vajira Hospital between January 1994 and December 2014 were identified. Clinico-pathological data were analyzed. Prognostic outcomes were examined by Kaplan-Meier curves and Cox regression analysis. Results: We identified 46 uterine sarcoma patients: 25 carcinosarcoma (CS) (54.3%), 15 leiomyosarcoma (LMS) (32.6%), and 6 undifferentiated uterine sarcoma (UUS) (13.1%) cases. Mean age was 54.011.9 years (range 25-82 years). Abnormal uterine bleeding was the most common presenting symptom (63.0%). Among 33 patients (71.7%) who had pre-operative tissue collected, diagnosis of malignancy was correct in 29 (87.9%). All patients received primary surgery and retroperitoneal lymph nodes were resected in 34 (73.9%). After surgery, 5 (10.9%) had gross residual tumors. Stage I disease was most commonly found (56.5%). Adjuvant treatment was given to 27 (58.7%), most commonly chemotherapy. After a median follow-up of 16.0 months (range 0.8-187.4 months), recurrence was encountered in 22 patients (47.8%). Median time to recurrence was 5.8 months (range1.0-105.5 months). Distant metastasis was more common than local or loco- regional failure. The 2-year PFS was 45.2% (95% confidence interval [CI], 30.6%-59.7%) and the 2-year OS was 48.3% (95% CI, 33.3%-60.7%). Multivariable analyses found residual disease after surgery as a significant factor only for PFS. Conclusions: Uterine sarcoma is a rare tumor entity. Even with multimodalities of treatment, the prognosis is still poor. Successful cytoreductive surgery is a key factor for a good survival outcome.
