A hemangiosarcoma of the abdominal wall developed in a long-standing, nonhealing radiation-induced ulcer ten years after therapeutic irradiation for endometrial carcinoma.

The use of radiation therapy to treat cancer inevitably involves exposure of normal tissues. Although the benefits of this treatment are well established, many patients experience distressing complications due to injury to normal tissue. These side effects are related to inflammatory processes, and they decrease therapeutic benefit by increasing the overall treatment time. Emerging evidence ...

BackgroundConcurrent chemoradiation with 5-fluorouracil (5-FU) is widely accepted for treatment of abdominal malignancy. Nonetheless, the interactions between radiation and 5-FU remain unclear. We evaluated the influence of abdominal irradiation on the pharmacokinetics of 5-FU in rats.MethodsThe radiation dose distributions of ...

We report a case of abdominal wall reconstruction following excision of irradiated skin and a ventral hernia. A very large tensor fascia lata musculocutaneous flap was used with good results. The anatomical features of this flap make it an excellent method of abdominal wall reconstruction.

Radiation therapy of abdominal lesions is problematic at best. The proximity of highly critical structures, tumor locations, and necessary margins combine to make prescription dose delivery with conventional 3-dimensional (3D) conformal techniques difficult. Others have tried to overcome these hurdles with newer modalities including intra-operative radiation therapy (IORT), ...

BackgroundThe prognosis for patients with advanced epithelial ovarian cancer remains poor despite aggressive surgical resection and platinum-based chemotherapy. More than 60% of patients will develop recurrent disease, principally intraperitoneal, and die within 5 years. The use of whole abdominal irradiation (WAI) as consolidation therapy would appear to ...

Hypertension secondary to stenosis of the left renal artery developed in a thirteen-year-old male six years after completion of inverted Y irradiation (3,600 rad) for abdominal Hodgkin disease. Surgical treatment with nephrectomy resulted in control of the hypertension without the use of antihypertensive agents. We review the literature for this unusual ...

The late effects of variable doses of abdominal irradiation on in vitro jejunal uptake were examined. The uptake of glucose, galactose, cholic acid, medium-chain length fatty acids, and decanol was studied 6 and 33 weeks following 300, 600, or 900 cGy abdominal irradiation. The intestinal morphological ...

Abdominal irradiation has recently been shown to influence the uptake of hexoses, amino acids, fatty acids and cholesterol into the jejunum of rats.

Experiments made with fractional irradiation of the abdominal cavity and of the whole body of pigs showed that the increase of D-xylose sorbtion depended on the dose. But there was a relation between disorders in sorbtion and severity of clinical, pathomorphological, and roentgenological changes. It is assumed that there may be consequences of ...

Liver slices removed from adult rats at various times following whole body x-irradiations of 850, 1500, and 2000 r were tested for their ability to metabolize hydrocortisone ( free alcohol). The animals were divided into a non- irradiated control group, an irradiated unshielded group, and an abdominal- ...

Purpose: Preoperative external-beam radiation therapy (preop RT) in the management of Retroperitoneal Liposarcomas (RPLS) typically involves the delivery of radiation to the entire tumor mass: yet this may not be necessary. The purpose of this study is to evaluate a new strategy of preop RT for RPLS in which the target volume is limited to the contact area between the tumoral mass and the ...

An inflammatory reaction is a classical feature of radiation exposure and appears to be a key event in the development of the acute radiation syndrome. We have investigated the radiation-induced inflammatory response in C57BL6/J mice after total abdominal or total-body irradiation at a dose of 15 Gy. Our goal was to determine the radiation-induced ...

We have previously reported that abdominal irradiation prior to i.v. injection of syngeneic tumor cells reduced metastases in lung. Our report described an investigation of the significance of intestinal organisms in the radiation effect. We found that eliminating intestinal organisms with antibiotics totally abolished the radiation effect. Monoassociation ...

Localized irradiation is a common treatment modality for malignancies in the pelvic-abdominal cavity. We report here on the changes in bone mass and strength in mice 7-14 days after abdominal irradiation. Male C57BL/6 mice of 10-12 weeks of age were given a single-dose (0, 5, 10, 15 or 20 Gy) or fractionated (3 Gy ...

Contribution from the irradiated secondary component is detected in the light curves of five dwarf novae observed during superoutbursts. Their superhump light curves show that irradiation is modulated with the superhump phase. This strengthens the new interpretation of superhumps as being due to the irradiation ...

By shielding abdominal segments III through V queen honey bees survived otherwise lethal doses of x radiation. In contrast, irradiating only segments III through V with 10,000 r killed all queens within three weeks, as did wholebody irradiations. Lead shields that protect segments III through V and permit ...

We report a primary vaginal angiosarcoma with widespread intra-abdominal metastasis occurring in a 73-yr-old woman 13 yr after vaginal brachytherapy for an endometrial carcinoma. This is an extremely rare phenomenon with only 7 previously reported cases of vaginal angiosarcoma, 5 of which were associated with earlier irradiation. All of the earlier ...

Occasionally surgeons have to operate on patients who have had previous abdominal or pelvic operations and irradiations for malignancies. Bowel resection with primary anastomosis under these circumstances is fraught with major complications such as anastomotic breakdown with intra-abdominal sepsis or recurrent enterocutaneous fistula, ...

Peritoneal mesothelioma in a 61-year-old man, occurred 26 years after abdominal radiotherapy for a testicular seminoma. The patient had no history of asbestos exposure. After asbestos, radiation is the second most frequent defined cause of mesothelioma in North America, but the number of well-documented cases is small; this case represents only the fifth example of peritoneal ...

For drug therapy a differentiation of acute and chronic pain is essential. In emergency situations of acute abdominal pain a fast diagnosis is mandatory. Analgesia should be provided as soon as possible. The different groups of analgesics should be used according to their known effects, side effects and contraindications. Postoperative pain after abdominal ...

Insects are easily distinguishable by the absence of legs on the adult abdomen. Studies performed on the Dipteran, Drosophila melanogaster, indicate that this is because of the repressive effects of the homeotic genes Ultrabithorax (Ubx) and abdominal-A (abd-A) on the limb promoting gene Distal-less (Dll) during embryonic development. However, in many species ...

Evidence has been presented which indicates that there is in the rat a substance or mechanism which under the influence of x-irradiation gives rise to a limited excretion of taurine.
