The results of the therapy of 46 patients with glottic squamous cell cancer with a fixed vocal cord and without regional lymph nodes (glottic T3N0) are reported. Primary surgery (total laryngectomy) in combination with preoperative irradiation gave significantly higher loco-regional control rate and survival rate than surgery alone. Primary radiotherapy with doses of 70 Gy or more and adequate follow-up was found to be an alternative to preoperative radiation and laryngectomy. The result of different treatment modalities speaks in favour of primary irradiation allowing preservation of the larynx and a good voice function. In case of recurrence salvage surgery with total laryngectomy is preferred.

Fifty consecutive massively obese patients referred for gastroplasty operations were prospectively studied to determine the existence of gastroesophageal reflux disease by means of a standardized questionnaire, 24-hr ambulatory pH-metry, and endoscopy (27 females, mean age 48 years, range 38-57 years). These patients had a body mass index (BMI) of 42.5 +/- 5.2 kg/m2 and an actual weight of 125.5 +/- 17 kg. Heartburn and acid regurgitation was reported by 37% and 28%, respectively, mostly of a mild degree (22% and 20%). Dysphagia was reported by 2%, but none had odynophagia. No patient had any macroscopic esophagitis. The pH data were compared with those obtained in 29 age- and sex-matched, symptom-free, healthy controls (15 females, mean age 47.6 years, range 30-63 years). During ambulatory pH-metry, we recorded a predominance of daytime reflux (7.2 +/- 8.2% and total acid exposure of 5.3 +/- 6.4%) in the obese patients, but neither the weight, BMI, nor the waist-hip ratio were significantly correlated with any of the reflux variables. The pH data obtained from these patients did not, however, differ significantly from those recorded in the control population, although a somewhat lower daytime acid reflux was found in the latter group. These results suggest that massive overweight is not associated with an increased prevalence of gastroesophageal reflux disease.

Summary. The scintigraphic detection of small nocturnal aspirations of radio-labelled gastric contents is difficult in the presence of high remaining activity in the abdomen, causing a non-uniform background activity. This problem was examined in phantom experiments and a technique for interpolative background correction was further developed. The accuracy of this technique was found to be influenced by the distance between the lung and the abdominal source of activity, and the minimum detectable ‘aspirated’ activity was determined as 0.1 MBq at a distance of 15 cm and 1 MBq at 5 cm. The interpolative technique for background correction was evaluated on healthy volunteers and laryngectomized patients, examined 10 h after intragastric instillation of 200 MBq of 99Tcm-pertechnetate. After background subtraction, their calculated pulmonary mean net count value was comparable to that registered before the radioactive tracer was administered. No localized accumulation of activity was found in any of these controls. The technique was then applied clinically to 55 patients with chronic respiratory disorders and symptoms of gastroesophageal reflux. Aspiration was detected in 11 patients (20%). Five aspirators had asthma, two a chronic cough of unknown origin, two recurrent pulmonary infections, and one chronic bronchitis and chronic laryngitis respectively. Aspiration was detected among patients with and without demonstrated pathological gastroesophageal reflux.

A retrospective study has been made of 302 patients with vocal cord carcinoma stage I and II treated between 1963 and 1983, emphasizing treatment failure patterns. The primary treatment modalities were radiotherapy for 266 patients and surgery for 36 patients. The minimum follow-up was 4 years. After primary radiotherapy there were 63 local recurrences and 7 neck lymph node recurrences, all appearing outside the target volume. The actuarial loco-regional recurrence-free rates at 5 years were 78% for T1, 76% for T2a (normal cord mobility) and 60% for T2b (impaired cord mobility) tumors. The actuarial regional lymph node recurrence-free rates at 5 years were 99, 100 and 93% for T1, T2a and T2b tumors respectively. The actuarial corrected survivals at 5 years were 95, 96 and 79% for T1, T2a and T2b tumors with primary radiotherapy and salvage surgery for recurrence. Salvage surgery was less successful in T2b compared to T1 and T2a tumors. In conclusion, after primary radiotherapy with salvage surgery the loco-regional control rate was high and very similar for glottic cancer T1 and T2a but less satisfactory for T2b tumors. Regional lymph node metastases were not a large problem in any of the subgroups. More effective radiotherapy with higher dose levels or an altered fractionation might increase the local control rate for T2 tumors with impaired cord mobility.

A questionnaire study was conducted to assess the prevalence and severity of symptoms suggestive of esophageal disorders in a general population. The study included 407 randomly selected subjects, evenly distributed in terms of sex and age, within the age span of 20-79 years. A total of 337 subjects replied (85%). Symptoms suggestive of gastroesophageal reflux were found among 25% of the participants. Cough on swallowing was common (27%), as was globus (16%) and chest pain (13%). In addition, dysphagia was reported by 10% and vomiting by 9%. The symptoms were usually mild, and moderate to severe symptoms were reported only occasionally (1-4%). No statistical correlation was found between esophageal symptoms and age, sex, or the reported consumption of tobacco, alcohol, or non-steroidal anti-inflammatory drugs. The frequency of heartburn and/or acid regurgitation was twice as common among those with symptoms of respiratory disease as among those with no respiratory complaints. A stepwise logistic regression analysis showed that a chronic cough and/or breathing difficulties were significantly related to the presence of symptoms suggestive of gastroesophageal reflux.

Ankylosis of the cricoarytenoid joints due to rheumatoid arthritis can cause severe laryngeal obstruction. With a mobilization and laterofixation procedure, five of six patients were successfully operated upon. Documented improvement of breathing was achieved and the voice function was acceptable after decannulation.

260 consecutive cases of jaw fractures were seen during a two-year period. A follow-up 6 months after treatment covering 81 patients showed that the dental injuries are the most important sequelae of a jaw fracture; The complications noted at treatment had been fewer except for the disorders of the temporo-mandibular joint which had an increasing tendency. It was striking to note the great falling off percentage of suspected alcohol abuses, i.e. patients injured by assaults and falls.

Intraluminal pressure recordings were made from the pharynx and the oesophagus in patients with laryngeal cancer. Before the laryngectomy no pathological recordings were found. After the operation none of the patients complained of dysphagia, but most of them showed well—defined alterations in the intraluminal pressures. After swallowing, relaxation and contraction pressures and resting tonus in the pha—ryngo—oesophageal sphincter were weaker. Peristalsis in oesophagus was usually good. The importance of early training of the oesophageal voice is stressed. Early function of the hypopharyngeal wound area seems to be important.

Twenty-two consecutive patients with gastroesophageal reflux and erosive or ulcerative esophagitis entered a double-blind, randomized study comparing the effect of 20 mg omeprazole once daily with that of 150 mg ranitidine twice daily on esophageal acidity. Ambulatory 24-h esophageal pH measurements were performed within 1 month before inclusion and after 3 weeks of medication. Omeprazole significantly (p less than 0.05) reduced the number of reflux (pH less than 4) episodes, the number of refluxes lasting greater than 5 min, and the total reflux time. In contrast, ranitidine significantly reduced only the total reflux time. When the two treatment groups were compared, a significant difference in favor of omeprazole was found for daytime and total reflux values, except for the longest reflux and the number of reflux episodes lasting greater than 5 min. Substantial differences, also in favor of omeprazole, were found with regard to the effect on endoscopic healing of the esophagitis.

A retrospective study of 65 patients with thyroid carcinoma treated 1966–1977 at the ENT-clinic is reported. Fine needle biopsy was very valuable for preoperatively diagnosis and arterial thyroid angiography was found of value to detect non-palpable metastases. 55 patients were treated surgically in 10 cases with extensive surgery. The anaplastic carcinoma cases had a bad prognosis either operated upon or given radiation.

IT has recently been demonstrated that reparatively growing tissues in skin wounds in the rat produce histamine at a high rate as a result of increased activity of histidine decarboxylase1. Further, the rate of repair, as measured by the tensile strength of the healing wound in situ, can be augmented or retarded, respectively, by artificial increase or inhibition of the histamine-forming capacity of the growing tissues. In these experiments the histamine-forming capacity was increased by injections of the histamine liberator 48/80, which depletes the skin of its histamine content and concomitantly raises the skin level of histidine decarboxylase. Extracellular histamine, derived from injected ‘long-acting histamine’, had no detectable effect on growth in healing. It was concluded that only intracellularly formed ‘nascent’ histamine is active in promoting certain types of growth2.
