Fluorescence in situ hybridization results in the carcinomas and benign mucosa of patients with schistosomiasis were compared with flow cytometric DNA ploidy and cell cycle assays.

Fluorescence in situ hybridization results in the carcinomas and benign mucosa of patients with schistosomiasis were compared with flow cytometric DNA ploidy and cell cycle assays. These results demonstrate the feasibility of this technique for studies of these archival specimens, and suggest early onset of chromosomal aberrations in histologically benign mucosa of schistosomal cystitis with progression during the development of bladder cancer. On the basis of these data, monosomy 9 may be an early chromosomal change in urothelium of the bilharzia-infested bladder, and a predictor of incipient carcinoma in patients with bilharzial cystitis.

The aim of this study is to report on our experience in draining pancreatic pseudocysts and probe the necessity or otherwise of obtaining a wall biopsy at drainage. Operation theatre registry, operation log books and medical records at Aseer Central Hospital, Abha, Kingdom of Saudi Arabia, were reviewed to retrieve the clinical details of patients with pancreatic pseudocyst who required a drainage procedure in a 13 years period from August 1989 to November 2002. Sixteen patients were identified. Cyst wall biopsy was obtained in 10 cases, in 8 of them the diagnosis was confirmed, while a true cyst was found in the remaining 2 excluding them from further analysis. In the remaining 14 cases (8 males, 6 females, mean age 38 years, range 4-60), pain was the main presenting feature. Open internal drainage wa...

The purpose of this study is to present the results of tissue expansion in reconstruction of pediatric head and neck defects. This clinical series includes 46 patients with an average age of 6.7 years, who underwent tissue expansion reconstruction of large head and neck defects at Cairo University Hospitals between January 2004 and June 2007. A total of 50 expanders were used. Expanded flaps were designed as advancement (N=34), rotational (N=14) and transposition (N=2). The average follow up period was 18.3 months. Complete coverage of the defect was achieved in 91.3% (N=42) with excellent tissue match. The complication rate was 14% (N=7). Complications included exposure (N=3), infection (N=3) and expander failure (N=1). The overall outcome was rated to be good in 52.2% (N=24), satisfactory in 34.8% (N=16) and fair in 13% (N=6). Tissue expansion can be successfully used in reconstruction of large head and nec...

This work aimed to ascertain results in a larger number of patients, finding practical method for implantation, studying the effect of changing weight of implant and effect of passage of time on its function. Forty patients had total thyroidectomy for simple multinodular goiters. A piece of the excised gland was finely minced, mixed with saline as emulsion, and injected in thigh muscles. Twelve patients had 5-g implants, while 28 patients had 10-g implants. Four parameters were studied at 2 months, 6 months, and 12 months: technetium isotope uptake by the implant; thyroid stimulating hormone (TSH); free T3 (FT3); and free T4 (FT4). All autotransplanted thyroid tissue survived and functioned. After 12 months, mean values (± standard deviation) of isotope uptake, TSH, FT3, and FT4 of the 5-g implants were 0.44 ± 0.16%, 27.74 ± 30.4 UI/mL, 3.07 ± 1.10 pg/mL, and 1.01 ± 0.3 ng/dL, repectively. Those for the 10 g implants were 0.71 ± 0.20%, 22.78 ± 19.7 UI/mL, 3.92 ± 1.2 pg/mL, and 1.05 ± 0.3 ng/dL, repectively. Ten-gram implants showed significantly higher isotope uptake than 5-g. TSH, FT3, and FT4 significantly improved over the period of 1 year. Injection of thyroid tissue suspension is a simple method for thyroid autotransplantation. TSH was elevated in the majority to maintain normal or near normal thyroid hormones. Ten-gram implants showed higher isotope uptake than 5-g, although this difference was not reflected by thyroid hormone profile. The implant seemed to function better with the passage of time from 2 months to 12 months.
