A new type of sliding hiatus hernia.

A series of patients showing a previously unrecognized type of sliding hiatus hernia is presented and analyzed. This type of hernia is characterized by reflux of the mucous membrane of the Hiss angle into the lumen of the esophagus. The occurrence of mucosal prolapse is a secondary phase of gastroesophageal reflux. The mucous plug prevents further reflux of the acid contents of the stomach into the esophagus and mouth. After the appearance of mucosal prolapse, the symptoms and signs of esophagitis disappear. The most characteristic complaint of the patients is retrosternal pain on lying and bending down. Endoscopy with provocative tests reveals the mucosal prolapse. Tooth erosions due to previous acid reflux into the mouth are diagnostic. The symptoms of this new subtype of sliding hiatus hernia were cured by the Nissen fundoplication.

Determination of axillary nodal status in surgery of breast carcinoma: a prospective study of thirty-five patients.

Thirty-seven axillary status of patients with breast carcinoma was studied with preoperative and peroperative palpation before mastectomy and total axillary dissection. Special attention was paid to the clinical suspiciousness and size of axillary nodes. The preoperative axillary palpation gave false diagnosis of axillary content 27% of the time and peroperative, 19%. Of all 249 nodes studied, 54 were found to contain malignant growth in routine histological examination. Mean diameter of malignant nodes was 12.4 mm and of benign nodes, 6.3 mm. The most clinically suspect axillary lymph node gave correct diagnosis of axillary status in 72% of the cases. The 2 most suspect lymph nodes together were positive in 89%. There was no case with histologically positive axilla where none of the 3 most suspect lymph nodes was malignant. We conclude that at least the 3 most suspect axillary lymph nodes must be removed for histological examination to be sure that axillary metastasizing of breast carcinoma can be found by routine histological examination.

Comparison of cefuroxime and gentamicin in combination with metronidazole in the treatment of peritonitis due to perforation of the appendix.

A study on 42 surgical patients was carried out to find out whether cefuroxime may be substituted for gentamicin in combination with metronidazole in the treatment of peritonitis secondary to perforation of appendix. All patients recovered and there were four wound infections in each group. Both aerobic and anaerobic bacteria were cultured in the peritoneal fluid in 69% of cases and anaerobes only in 19% of the patients. Postoperatively the patients were followed up for one month. The mean length of the hospital stay and convalescence did not differ significantly. There was also no difference in the time to the removal of gastric suction, laboratory measurements and the incidence of pyrexia between the study groups. Although the number of patients was limited the present study indicates that gentamicin may be replaced by less toxic cefuroxime. This is especially the case if there are several risk factors in the use of gentamicin and if there is not a possibility for monitoring the serum levels of gentamicin.

Treatment of spontaneous rupture of the esophagus.

A series of 10 patients with spontaneous rupture of the esophagus is analysed. Early primary closure of the tear and good drainage of the mediastinum and pleural cavity give the best results in such cases. Correct diagnosis is difficult and is often missed in the acute phase. The time lapse between the rupture and diagnosis nevertheless seems to be the most important single factor in the outlook for treatment of spontaneous rupture of the esophagus.

Metronidazole prophylaxis against wound infection in patients undergoing appendicectomy.

The effect of a preoperative single intravenous dose of metronidazole was studied in a prospective trial of 203 patients. 17.5% of the patients in the control group developed a wound infection compared with 3.4% of those receiving metronidazole (p less than 0.001). The average length of hospitalization and convalescence was significantly reduced in the metronidazole group. The use of metronidazole in prevention of wound infection is recommended.

Acute and subacute effects of diazepam on psychomotor skills: interaction with alcohol.

Effects of diazepam and alcohol on psychomotor skills were measured in two trials. In the first one, 200 healthy students volunteered for a double-blind single-dose study. Three doses of diazepam (5, 10 and 20 mg) and alcohol (0.5, 0.8 and 1.2 g/kg) were used alone and combined to construct dose-response graphs. All doses of alcohol impaired divided attention while co-ordinative skills were impaired by the 1.2 g/kg dose. Diazepam alone did not impair reactive or co-ordinative skills whereas the combinations of diazepam and alcohol did so. To further elucidate the subactue effects, a double-blind randomized study was conducted administering 2 and 10 mg of diazepam t.i.d. for two weeks to 18 healthy volunteers. The psychomotor tests were performed on the 7th and 14th days of drug administration, and 0.5 g/kg of alcohol was given on either day. Diazepam 2 mg, alone or with alcohol, did not differ from placebo. 10 mg of diazepam slightly increased reaction times but not reaction mistakes, and impaired both co-ordination and attention. Alcohol did not enhance diazepam effects. We suggest that a development of tolerance to diazepam may compensate the deleterious interaction of the agents found in acute studies.

Rupture of the penis.

Traumatic rupture of the penis is a rare accident. One or both corpora cavernosa may be affected. Approximately one third of the cases are associated with rupture of the urethra. In view of previous studies, and the present case reports both of which occurred during the same night, the authors propose primary surgical repair of the corpora cavernosa.

Effect of alcohol and benzodiazepines on performance as related to personality characteristics. Personality characteristics among healthy "placebo reactors" and nonreactors.

For 2 weeks 40 volunteers received either 5 mg diazepam, t.i.d., or 10 mg chlordiazepoxide, t.i.d., and placebo. A choice reaction test, two coordination tests, and an attention test were administered to the subjects on the 14th day of each treatment. Thirty minutes before the tests, the subjects ingested either alcohol., 5g/kg or a placebo drink, incombination with the last capsule. After the test the subjects rated the quality of their treatment as placebo, tranquilizer, or stimulant. The psychological tests taken before the treatments were Eysenck's EPIC-NESI, Taylor's Manifest Anxiety Scale (MAS), and Cattell's 16 PF inventory. A multiple regression analysis was computed. Personality factor scores found to be associated with a strong effect of the benzodiazepines were 16 PF's A, C, L, N, and Q, and EPIC's E. The effect of alcohol was associated with a high score of 16 PFs B factor. Personality factors associated with "placebo reactors" and nonreactors were investigated, as well. Those subjects on placebo indicating their treatment to be active were classified as "placebo reactors". A discriminant analysis revealed that 16PF's O and I factors discriminated effectively "placebo reactors" from nonreactors, and EPIC's SE and 16 PF's L factor nonreactors from "reactors".

Modification by diazepam or thioridazine of the psychomotor skills related to driving: a subacute trial in neurotic out-patients.

Forty-five out-patients with clinically manifested anxiety were tested in order to study the effects of 2 weeks' treatment with placebo, diazepam (5-10 mg three times daily) or thioridazine (25-50 mg three times daily) on their psychomotor skills related to driving. When compared with placebo, diazepam increased the number of mistakes in reaction and co-ordination tests and also decreased ability to discriminate the fusion of flickering light. When compared to other groups, reactive and co-ordinative skills were more impaired in patients treated with thioridazine which also impaired divided attention. Aubjectively thioridazine was not experienced as effective an anxiolytic as diazepam.

Two weeks' treatment with chlorpromazine, thioridazine, sulpiride, or bromazepam: actions and interactions with alcohol on psychomotor skills related to driving.

Subacute effects of C, T, S, or B, alone or in combination with A, were tested against P in two double-blind crossover trials with 37 healthy students. The drugs were given in capsules t.i.d. for 2 weeks each and the psychomotor performance (choice reaction, coordination, attention) was measured on the 7th and 14th days of treatment. At each session the subjects swallowed a capsule together with 0.5 g/kg of A or P drink, and the measurements were done, 30, 90, and 150 min thereafter. T alone did not differ from placebo in the doses used (10 mg t.i.d. for 7 days and 20 mg t.i.d. for the next 7 days). After C (dosing as above) and S (50 mg t.i.d.) both reactive and coordinative skills were slightly impaired. B (6 mg t.i.d.) clearly impaired both reactive skills and attention. T + A had no major combined effect on skills while C interacted with A resulting in impaired reactive and coordinative skills. After C + A the subjects were unable of compensating their coordination mistakes by slow driving. The interaction of S with A was mild, whereas B + A strongly impaired coordination and divided attention. No alterations were recorded in flicker fusion after any treatment.

Psychomotor skills during subacute treatment with thioridazine and bromazepam, and their combined effects with alcohol.

Twenty paid healthy students volunteered for a doubleblind cross-over trial on the effects of two weeks' treatment with placebo, thioridazine and bromazepam on psychomotor skills. The doses used were thioridazine 10 mg t.i.d. during the first week and 20 mg t.i.d. during the second week, or 6 mg of bromazepam t.i.d. during two weeks choice reaction test, two co-ordination tests, a divided attention test, flicker fusion, and proprioception tests were used. The psychomotor skills were measured in the afternoon of the 7th and 14th day of each treatment, 30, 90 and 150 minutes after the second daily administration of the drug in combination with either an alcoholic or a placebo drink. There were no significant differences between the test weeks. Thioridazine alone resembled placebo and had no major combined effect with alcohol. Bromazepam impaired reactive and co-ordinative skills and attention deteriorated. The combination of bromazepam and alcohol potentiated the deterious effects of the single agents, and this effect was most remarkable at 30 minutes. The subjects also gave exaggerated responses in the proprioceptive tests. No significant alterations were recorded in the flicker fusion frequency after any treatment.

Effect of two weeks' treatment with thioridazine, chlorpromazine, sulpiride and bromazepam, alone or in combination with alcohol, on learning and memory in man.

Forty paid healthy male students participated in two subacute experiments of 6 weeks each. In the first trial 20 of them received bromazepam, thioridazine, and placebo double blind cross over for 2 weeks each, and in the second trial the active agents administered to the other 20 participants were chlorpromazine and sulpiride. The tests used were paired associate learning with nonsense syllables and digit memory span. Before testing the subjects took either an alcoholic or a nonalcoholic bitter drink. As in the previous study from this laboratory, alcohol was found to impair learning capacity. Of the drugs used only bromazepam impaired learning significantly, and the combined effect of alcohol and bromazepam on learning capacity was very deleterious. The adrenolytic effect of drugs did not correlate with their effect on learning. Caution is necessary when prescribing bromazepam for active outpatients at least in doses used in this study.

Effect of two weeks' treatment with chlordiazepoxide or flupenthixole, alone or in combination with alcohol, on psychomotor skills related to driving.

The effects of two weeks' treatment with chlordiazepoxide 10 mg t.i.d. or flupenthixole 0.5 mg t.i.d. on human psychomotor performance related to driving was examined on 20 healthy male students aged 20 to 23 years. The tests used were a choice reaction, two co-ordination and an attention test having correlation with traffic behaviour. Neither chlordiazepoxide nor flupenthixole impaired psychomotor performance on the 7th or 14th days of the experiment. The combination of either drug with 0.5 g/kg of alcohol impaired co-ordination and attention to an extent which can be considered dangerous for traffic and occupational life. Their interaction with alcohol was not so strong as that between diazepam and alcohol. The combination of chlordiazepoxide with alcohol tended to increase the anxiety of the normal subjects.

The management of non-neoplastic esophageal perforation.

The clinical features, management and prognosis of non-neoplastic esophageal perforation are evaluated in a clinical series of 29 patients. Five of 12 spontaneous ruptures were caused by vomiting after alcoholic intake. There were 12 iatrogenic perforations, five of which were caused by esophageal dilatation, four by diagnostic endoscopy and three by endoscopic removal of foreign bodies. Most cases were diagnosed by esophagogram. The delay in reaching the right diagnosis was less than 12 hours in 11 cases and more than 48 hours in ten cases. Management was surgical in 25 cases and conservative in four cases. The operative procedures used were direct suture closure in 15 cases, drainage in eight cases and esophageal resection in two cases. The overall mortality rate was 24%. Ten out of 11 perforations treated surgically within 12 hours of the perforation were cured and seven of 15 patients treated by primary closure recovered without complications.
