Clear cell carcinoma of the uterine cervix is rare type of the uterine cervical adenocarcinoma. Although uterine cervical adenocarcinomas presently represent 20% to 30% of cervical cancers in the industrialized countries, the clear cell carcinoma of uterine cervix is very rare malignancy that accounts for 4% to 9% of the adenocarcinoma of uterine cervix. This malignancy occurs in two distinct age groups; those younger than 24 years and those older than 45 years. In younger patients, most of these malignancies are mainly related to prenatal diethylstilbestrol (DES) exposure, but older patients are unrelated to in utero DES-exposure. We experienced a case of clear cell carcinoma of the uterine cervix of 34 years old housewife who was not related to prenatal DES-exposure. We presented a case with a brief review of related literatures.

Clear cell adenocarcinoma (CCAC) is a rare cancer that comprises less than 9% of the cervical adenocarcinoma cases. We experienced a case of fertility-sparing radical abdominal trachelectomy for cervical clear cell adenocarcinoma (CCAC). Thus, reported it. A 27 year old female was diagnosed with clinical stage Ib cervical CCAC. She had no history of maternal exposure to diethylstilbestrol and had negative PAP cytology and HPV tests. She was treated with neoadjuvant chemotherapy followed by radical abdominal trachelectomy. After 2 cycles of postoperative adjuvant chemotherapy, the lesion disappeared completely in an imaging study, and potential fertility was preserved. Radical abdominal trachelectomy with chemotherapy may be a valuable approach for treating stage Ib cervical CCAC in women that wish to preserve potential fertility.

We report a case of Undifferentiated carcinoma of the prostate in a 66 years old male resulted in severe chronic anemia (Hb value: 2.9gm/100dl, Hct:9%). The patient was treated with multiple blood transfusions, diethylstilbestrol and cystostomy with good improvement of general condition.

Endometrial cancer is the most common gynecologic malignancy in developed countries. Clear cell carcinoma typically occurs in the ovaries, and very rarely occurs in the endometrium; it accounts for less than 3% of all endometrial cancers. It is presumed that clear cell carcinomas are of Müllerian duct origin, and an association with exposure to diethylstilbestrol (DES) or other nonsteroidal follicle stimulating hormones has been described. We report a case of a postmenopausal woman who presented with vaginal bleeding without a specific medical history. Under the impression of an endometrial mass, we performed a laparoscopic operation. Pathologic results showed clear cell carcinoma of the endometrium. Depth of invasion was 0.2 cm out of a 0.5 cm total thickness, and the rectal shelf mass was clear cell carcinoma. We report the case with a brief review of the relevant literature.

Clear cell carcinoma of the uterine cervix is rare cancer that accounts for 4 to 9% of the adenocarcinoma of uterine cervix. Although intrauterine exposure to diethylstilbestrol (DES) during early pregnancy is one of the established risk factors, DES exposure may not be confirmed in all patients. We experienced a case of clear cell carcinoma in the uterine cervix of 67-year-old woman who was not exposed to DES. She was initially diagnosed as endometrial clear cell carcinoma because of the normal colposcopic finding and histologically proven clear cell carcinoma from endometrial aspiration biopsy and endocervical curettage. We performed a total laparoscopic hysterectomy with bilateral salpingo-oophorectomy and lymphadnectomy including both pelvic and para-aortic regions. On the final pathologic diagnosis of clear cell carcinoma confined to endocervix, the patient was received adjuvant concurrent chemoradiation with weekly cisplatin. We present the case with a brief review of related literature.

The mullerian ducts join the sinovaginal bulb at a point known as the mullerian tubercle. Canalization of the mullerian tubercle and sinovaginal bulb is necessary to give a normal vaginal lumen. If the area of junction between these structures is not completely canalized, a transverse vaginal septum will occur. This may be partial or complete and generally lies at the junction of the upper third and lower two thirds of the vagina. It occurs in about 1 per 75,000 females. Partial transverse vaginal septa have been reported in diethylstilbestrol (DES)-exposed females. In the prepubertal state, diagnosis is generally not made unless there is the development of a mucocolpos or mucometrium behind the septum. At puberty, however, if the septum is complete, hematocolpos and hematometrium may occur in a fashion similar to that seen in the imperforate hymen, except that there is no bulging at the introitus. The patient with an incomplete transverse septum may bleed somewhat but will still develop hematocolpos and hematometrium over time and may also complain of foul smelling vaginal discharge.

AIMTo fabricate multi-wall carbon nanotube (MWNT) modified electrode and study the electrochemical behaviors of diethylstilbestrol at the MWNT-modified electrode.

METHODSCyclic voltammetry and linear sweep voltammetry.

RESULTSThe oxidation peak current of diethylstilbestrol increased remarkably and the peak potential shifted negatively at the MWNT-dihexadecyl hydrogen phosphate (DHP) modified glassy carbon electrode (GCE), in contrast to that at the bare GC electrode and DHP-modified GC electrode. The oxidation peak current is linear with the concentration of diethylstilbestrol over the range from 1 x 10(-8) to 2 x 10(-6) mol.L-1. The detection limit was 2.5 x 10(-9) mol.L-1. The relative standard deviation (n = 10) was 2.9% for 1 x 10(-6) mol.L-1 diethylstilbestrol.

CONCLUSIONThe MWNT-DHP modified GCE exhibits catalytic activity to the oxidation of diethylstilbestrol.

OBJECTIVETo develop a quartz crystal microbalance (QCM) immunosensor with high sensitivity and selectivity for the rapid detection of diethylstilbestrol.

METHODSDextran was used as reducing agent for preparing gold nanoparticles (AuNPs) with the size of 40 nm. The AuNPs were coupled with anti-DES antibody after amination. A monolayer was generated after immersing the quartz crystal into the solution of 5 mmol/L 11-mercaptoundecanoic acid(MUA) for 16 hours. After the monolayer was activated by 1-ethyl-3-(3-dimethylaminopropry) carbodiimide hydrochloride (EDC·HCl) and N-hydrosuccinimide (NHS), 20 μl of 2.2 mg/ml DES-HS-BSA was dropped onto the surface of crystal to prepare a sensitive membrane which can recognize DES specifically. Then, 50 μl of 1 mol/L ethanolamine (pH 8.5) was used to seal the carboxylic groups to make the sensitive membrane which could identify DES specifically. QCM immunosensor was used as detection platform to optimize the reaction conditions. Under the optimized conditions, 10 μl of 28 μg/ml AuNPs-antibody was mixed with 10 μl of 0.03-2.5 μg/ml DES, and the mixture was added on the sensitive membrane. QCM immunosensor was used to detect the signals and the standard curve was obtained at the same time. The detection limit was calculated based on the standard curve. The specificity was evaluated by testing DES and its analogues with the same concentration.

RESULTSThe optimized concentration for the immobilization of DES-HS-BSA on the surface of QCM was 2.2 mg/ml. The optimized concentration for coupling anti-DES antibody with AuNPs was 7 μg/ml and 15 nmol/L, respectively. The optimized concentration of AuNPs-antibody was 14 μg/ml. The logarithm of DES concentration was proportional to the frequency shift in the range of 0.16-500 ng/ml, Δf=-24.170 lgCDES+69.71, R(2)=0.998. The detection limit of this method was 0.13 ng/ml. DES analogues could not influence the detection of DES obviously, so the sensor had good specificity.

CONCLUSIONThe quartz crystal microbalance immunosensor with gold nanoparticals amplification could detect DES sensitively and rapidly.
