A study on patients treated with polyacrylamide hydrogel injection for facial corrections.

Polyacrylamide hydrogel (PAAG) has been used as a tissue filler in facial corrective surgery and for breast augmentation in Kiev, Ukraine, for more than 10 years with reportedly very good results. These results, however, have not been published in peer-reviewed journals. A Danish/Swedish group of plastic surgeons with special interest in facial corrective surgery did a retrospective, systematic, pre-planned investigation of 104 patients treated at the center in Kiev.

Long-term effects of polyacrylamide hydrogel on human breast tissue.

Polyacrylamide hydrogel is an atoxic, stable, nonresorbable sterile watery gel consisting of approximately 2.5% cross-linked polyacrylamide and nonpyrogenic water. Polyacrylamide hydrogel is widely used in ophthalmic operations, drug treatment, food packaging products, and water purification.

[Employment of prolene net in ventral hernia].

Patching with prolene net in cases of ventral hernia where it is not possible to close the defect in the abdominal wall with the patient's own tissue has been employed since 1979 in several departments for plastic surgery. Our clinical experience from 1979 to 1985 in 55 patients submitted to this form of operation shows that this is an employable method with few peroperative and postoperative complications and with satisfactory results over a prolonged period. Satisfactory results have been obtained, in particular, in patients with chronic bronchitis and obstructive pulmonary disease and several previous herniotomies.

Mustard gas: clinical, toxicological, and mutagenic aspects based on modern experience.

Based on a study of the literature and our own experience treating fisherman poisoned by mustard gas, this article outlines the clinical effects, and toxicological and mutagenic properties of the agent. Mustards are very persistent chemical agents that easily penetrate clothing. Mustard gas usually causes clinical symptoms after the liquid penetrates the skin or the vapor is inhaled.

Bronchial carcinoid tumours. A clinicopathologic study of 82 cases.

A clinical and "blind" histologic review of 82 cases of bronchial carcinoid tumour is presented. The malignant potential of the tumours was only partly predictable from their histologic appearance. Histologically 65 of the tumours were typical benign carcinoids.

Superior vena caval syndrome in benign mediastinal goitre.

The superior vena caval syndrome is the clinical condition which develops at too high a pressure in the superior vena cava and the afferent veins. Its aetiology has changed in the course of time, but at present 97% of the cases are due to intrathoracic malignancy. An extremely rare aetiological factor is substernal and intrathoracic goitre.

Isolated middle lobe atelectasis: aetiology, pathogenesis, and treatment of the so-called middle lobe syndrome.

Isolated atelectasis of the middle lobe has been known for many years as the "middle lobe syndrome". Several clinical studies have shown that it may bae caused by malignant tumours. A 10-year study of 135 patients with isolated middle lobe atelectasis is presented.

Results of operative treatment of hypopharyngeal diverticulum.

The so-called hypopharyngeal diverticula may be classified, according to their size, localization, and form, into three stages. Small diverticula (first stage) should not be surgically removed, whereas all other diverticula, that is, those causing symptoms, must be surgically removed as soon after diagnosis as possible. Diverticulectomy performed in one stage is the treatment of choice.
