[Endoscopic treatment of gastroduodenal digestive hemorrhage].

Endoscopy is extremely useful for the diagnosis of upper gastrointestinal bleeding. At the present time, therapeutic measures are been used during the endoscopy to stop bleeding. This paper reports the experience of hospital de Talca in the endoscopic treatment of upper gastrointestinal bleeding. Thirty four patients (22 male) with bleeding not originating from esophageal or gastric varices were treated with direct absolute alcohol injection into the bleeding lesions. The procedure was successful in 31 patients. Three of the 34 patients required surgery, but only one of those successfully sclerosed (97% success). There were no complications attributable to the procedure. It is concluded that this therapeutic modality must be implemented in places were gastrointestinal endoscopy is performed.

Subperiostic lifting.

Usually in subcutaneous or muscular rejuvenation techniques, work is concentrated on the lateral regions of the face and particularly on the cheek and cervical area. However, results are poor in the temporoparietal area and are virtually nonexistent in the frontonasal area. By making a coronal incision and extending it into the preauricular area followed by a subperiosteal approach so as to free the frontonasal, orbital rim, and zygomaticomalar areas, we can completely mobilize the upper half of the face thus improving it aesthetically.

[Digestive diseases in the elderly].

This study was carried out in two phases. First a survey was done, interviewing 57 apparently healthy persons, who were older than 60 years. Information was collected about previous illnesses and any digestive symptoms. Then a prospective study was developed in 43 out patients seen previously in a gastroenterological centre (aged 60 or older). The frequency and type of digestive diseases for this group of patients was established. Nineteen (33.3%) of the former 57 patients from the survey referred frequent digestive discomfort, predominantly symptoms related to the upper gastrointestinal tract, like epigastric pain, meteorism, early satiety, abdominal distention and pyrosis. These symptoms could be in part expected due to the physiological changes seen in the elderly, mainly in the esophagus. In the prospective study, digestive diseases related to the upper gastrointestinal tract were the most common (46.5%), followed by diseases from the colon and rectum (23.2%) and those of the liver, biliar tract and pancreas (16.2%). Taking into account the high incidence of gastrointestinal symptoms in the elderly, we must make special efforts to extend and or complete studies related to the geriatric population in our country. We need to establish rules for the control, prevention and early detection of such illness in order to promote higher standard in the quality of the life of population which will increased considerably in the near future.

[Ileorectal anastomosis: results of surgical treatment and evaluation of the intestinal function].

Ileo-rectal anastomosis was performed in 30 patients. Indication for surgery was ulcerative colitis in 12, cancer of colon in 10 and megacolon in 6. Mean age of patients was 47.8 years with an even sex distribution. Ileo-rectal anastomosis was performed simultaneously with total colectomy in elective patients (n = 18) and at a second stage, following transient terminal ileostomy in emergency cases (n = 12). An overall morbidity of 26% was observed: wound infection developed in 13%, prolonged ileus in 7%, intraabdominal abscess in 3% and fistula of the anastomosis in 3%. There was no mortality. After a mean follow up of 36 months there was no instance of incontinence, average number of daily intestinal evacuations was 2.4 (somewhat higher for patients with ulcerative colitis: 2.6 vs 2.1). We conclude that ileo-rectal anastomosis is a safe procedure with adequate functional results.

Liposuction in cervical rejuvenation.

Superficial musculoaponeurotic system (SMAS) has represented a confusing anatomical structure because descriptions of it in classical treatises of anatomy are contradictory. Also, utilization of this system in facial rejuvenation also does not coincide with the true anatomical facts regarding the superficial musculo-aponeurosis. A macroscopic and histological study of the region was carried out in order to determine the areas of fat deposits and the distribution of the true cervical superficial aponeurosis, partly in accordance with the statements by Jost and leaving aside the concept proposed by Mitz and Peyronie. Cervical liposuction was combined with the techniques for cervicofacial rhytidectomy.

Nonsuture surgery under microscopic control for basal cell carcinoma.

Nonsuture surgery under microscopic control consists of conservative surgical excision of the tumor leaving the wound open and allowing it to granulate. Using fresh tissue technique, the lesion is cut in multiple horizontal sections from the depth up and examined under the microscope. In this form, a simple office procedure, removal is complete with minimum destruction of normal tissue. Cosmetic results are excellent.

[Aging as inversion of growth: reaction of uric acid (author's transl)].

Independent from sex, the concentration of uric acid in serum decreases slowly in normal individuals from 55--58 years on. The older is an individual, the lower is the concentration of uric acid. This phenomenon is the consequence of a restriction of the synthesis of nucleic acids, parallel to ageing. Results suggests that the concentration of uric acids can be considered to be parameters of ageing.
