Analysis of the prognostic impact of tumor embolization before definitive radiotherapy for cervical carcinoma.

Purpose: To assess whether embolization compromises the radiocurability of primary cervical cancer.

Methods And Materials: Two hundred fifty-four patients with primary cervical cancer (International Federation of Gynecology and Obstetrics [FIGO] stages IB: 47; II: 91; IIIB: 102; IV: 14) were treated with external beam irradiation and Ir-192 high-dose-rate brachytherapy over a period of 15 years. Of these, 24 patients (9.

The incidence of gastroesophageal reflux after transthoracic esophagocardio-myotomy without fundoplication: a long term follow-up.

Objective: Evaluation of the long term results of Heller's myotomy performed over a lateral thoracotomy without additional fundoplication.

Methods: Forty patients (17 males, 23 females; mean age 43.2 years; range: 14-63 years) were operated between 1985 and 2000.

Stress-induced hormonal and mood responses in scuba divers: a field study.

The majority of injuries in scuba-divers are attributable to inappropriate behavior under stressful diving conditions, predominantly involving panic reactions emerging from elevated levels of anxiety. Divers with an elevated level of anxiety and poor coping are at higher risk of developing panic reactions than those possessing more adequate stress-coping-mechanisms. In the comparison of two extreme groups of seven divers each with opposite stress coping strategies, prolactin was found to be a hormonal marker with a significant increase in the sub-group of the stress-controllers.

Radiation-induced osteosarcoma of the chest wall.

A case of radiation-induced sarcoma of the chest wall is reported. Twenty-seven years 11 months after orthovoltage radiotherapy of the right breast a 69-year-old woman developed a radiation-induced osteosarcoma of the right thoracic wall. Initial diagnosis has been T-cell lymphoma of the skin.

Titanium vocal fold medializing implant: introducing a novel implant system for external vocal fold medialization.

With the increasing worldwide spread of the Isshiki technique for external vocal fold medialization, some disadvantages and limitations have also emerged. and an increasing demand for a ready-made and standardized implant system can be observed. For this reason.

The Graz hemisphere splint: a new precise, non-invasive method of replacing the dental arch of 3D-models by plaster models.

Three-dimensional (3-D) anatomical models have proven their great value in the field of cranio-maxillofacial surgery. One major disadvantage is the limited representation of the teeth in milled and stereolithographic models. This is mainly caused by the limited resolution of the CT-scan, especially in the plane perpendicular to that of the scan.

Indications and limitations of three-dimensional models in cranio-maxillofacial surgery.

Anatomical, life-like, three-dimensional (3D) models have a definite place in cranio-maxillofacial surgery. Our experience with 541 computer tomography (CT)-based 3D models employed in aiding corrective surgery of tumours, dysgnathia, traumatology, alveolar atrophy, congenital malformation and asymmetrical malformations in our department is discussed. From July 1988 to February 1997, 3D models of 346 patients were used.

Bladder and rectal dose of gynecologic high-dose-rate implants: comparison of orthogonal radiographic measurements with in vivo and CT-assisted measurements.

Bladder and rectal doses were retrospectively reviewed in 281 patients who underwent implantation of 575 gynecologic iridium-192 high-dose-rate devices. Dose measurements obtained with orthogonal radiography, in vivo thermoluminescent dosimetry, and computed tomography (CT)-assisted planning were compared. Measurements of bladder dose derived from radiographs revealed a significant difference between bladder neck dose and bladder base dose (P less than .
