Elaffandi, A. H., H. H. Khalil, H. A. Aboul Kassem, M El Sherbiny, and E. H. El Gemeie, "Vaginal reconstruction with a greater omentum-pedicled graft combined with a vicryl mesh after anterior pelvic exenteration. Surgical approach with long-term follow-up.", International journal of gynecological cancer : official journal of the International Gynecological Cancer Society, vol. 17, issue 2, pp. 536-42, 2007. Abstract

Resection of anterior vaginal wall that occurs with some cases of anterior pelvic exenteration leaves the patient with a small and narrow vagina. This affects their sexual life leading to major psychologic problems, especially in young women. The aim of this study is to evaluate a new technique of vaginal reconstruction following anterior pelvic exenteration with clinical and cytohistologic follow-up. Between March 2002 and November 2004, ten sexually active female patients underwent vaginal reconstruction after radical cystectomy that required en bloc removal of the anterior vaginal wall, with a pedicle graft of greater omentum combined with a vicryl mesh. The mean age of the patients was 38 years. The mean operative time of the reconstructive procedure was 50 min. There were no complications regarding the reconstructive procedure. On follow-up, the neovagina accepted two fingers easily and showed a pink-colored smooth lining. Seven patients reported successful attempts of sexual intercourse. It was concluded that reconstruction of vagina after anterior pelvic exenteration in sexually active women can be done safely with the use of vicryl mesh combined with a pedicled omental graft. It is a simple, reliable, and not time-consuming technique. The long-term follow-up was very beneficial in detection of complete healing, postoperative infections, and hormonal activity of the graft and recurrence of malignancy.

Quantitative multicomponent analysis is considered an analytical goal to save time and cost in analysis. Hence, this work aimed to provide sensitive and selective UV-spectrophotometric, chemometric manipulation, and ultra-performance LC (UPLC) methods for the determination of well-known coformulated antiemetics used in pregnancy, namely pyridoxine HCl (PYR), meclozine HCl, and cyclizine. The developed UV-spectrophotometric methods are dual wavelength in ratio spectra and first derivative of the ratio spectra with which PYR was determined selectively at 290.8 nm, whereas the other drugs in a ternary mixture were determined from their ratio spectra using a spectrum of PYR as a divisor in 0.1 M HCl. An ecofriendly partial least-squares regression chemometric method was applied to raw UV absorbance data for the determination of the ternary mixture in a 218-355 nm range using a three-factor, three-level design with water as the green solvent. A gradient UPLC method was developed and successfully resolved the ternary mixture within 5 min. Different ratios of water (adjusted to pH 3 with phosphoric acid) and methanol were delivered at 0.5 mL/min as the mobile phase into a Hypersil Gold C18 column (50 × 2.1 mm, 1.9 µm). The developed methods were successfully applied to different pharmaceutical formulations containing the aforementioned drugs and validated according to the International Conference on Harmonization guidelines. The results obtained were reproducible and reliable and can be applied for routine analysis and QC in laboratories.

Abstract

Two chromatographic methods were developed, optimized and validated for simultaneous determination of calcipotriol monohydrate (CPM) and betamethasone dipropionate (BMD) in the presence of two dosage form additives named; butylated hydroxytoluene (BHT) and alpha-tocopherol (TOCO). The proposed methods were accurate, sensitive and specific. The first method based on using aluminum thin-layer chromatographic plates precoated with silica gel GF254 as a stationary phase and chloroform-ethyl acetate-toluene (5:5:3, by volume) as a developing system. This was followed by densitometric measurement of the separated bands at 264 nm. Whereas the second method is RP-HPLC where OnyxMonolithic C18® column was used with a gradient profile using methanol, water and acetic acid at flow rate 2.0 mL min-1. Detection was carried out at 264 nm. The methods were validated according to ICH guidelines. The specificity of the developed methods was investigated by analyzing the pharmaceutical dosage form. The validity of the proposed methods was assessed using the standard addition technique. The obtained results were statistically compared with those obtained by the official methods, showing no significant difference with respect to accuracy and precision at P = 0.05.
