Massive intravenous bolus bretylium tosylate.

A 30 mg/kg (2-gm) intravenous bolus of bretylium tosylate was administered to a patient with recurrent ventricular tachycardia and fibrillation. After successful defibrillation the patient exhibited marked hypertension followed by protracted refractory hypotension. There was no further ventricular ectopy in spite of a very low cardiac index. A bretylium level of 8,800 ng/ml is the highest reported in man from a single bolus injection. This case demonstrates the exaggerated hemodynamic response to massive intravenous bolus bretylium tosylate.

Local cochlear masking by frequency-modulated tone bursts.

Masking experiments are demonstrated for electrical frequency-modulated tone bursts from 1,000 to 10,000 cps and from 10,000 to 1,000 cps with superimposed clicks. The maximum of the masking was found at 3,700 cps ("narrow-band masking").

[Mucoepidermoid tumor of the epipharynx].

Case report about a mukoepidermoid-tumor, which was investigated by means of histology and electron microscopy. The localisation of this tumor in the epipharynx is a rarity and unknown in the literature. The variable differentiated tumor consists of epidermoid cells with different graduation of maturity, of epithelial cells from the gland ducts and primitive acini as well as in the majority of undifferentiated cell types. The tumor seems to be of a "low grade malignity".

[The varied behavior of the nasal sinuses in cleft lip and palate with differing localization of the cleft (a radio-analytical study)].

Report on 301 radiographs of the paranasal sinuses of cleft patients and on 120 radiographs of the paranasal sinuses of subjects from a control group to illustrate the development of the maxillary and frontal sinuses. In female individuals as well as in male ones, the maxillary sinuses on the left side are greater than those on the right side. Aplasia of the frontal sinuses on the right side was observed in 11.7%; aplasia of those on the left side, in 3.3%. The maxillary sinuses on the side of the cleft are greater than those on the opposite side. In patients with clefts of the secondary palate, the maxillary sinuses are significantly greater than in patients with clefts of the primary palate or with subtotal or total clefts of the secondary palate. Aplasia of the frontal sinuses on the right side was seen in 11%; aplasia of those on the left side, in 6%.

Subcutaneous emphysema.

Subcutaneous emphysema is most often associated with thoracic pathology. The case is presented of a middle-aged woman with shock, abdominal distention and rigidity, and subcutaneous emphysema which resulted from a spontaneous gastric rupture. Subcutaneous emphysema has a variety of origins, including infections and rents in the respiratory tract, gastrointestinal tract, and the skin.

[Aplasia of the sinus maxillares and frontales under the special regard of the pneumatisation of cleft patients (author's transl)].

A report on 2820 x-rayfilms of the sinus maxillaris from adults, on 120 x-rayfilms from child-like and youthful patients as a control group and from 301 x-rayfilms from patients with cleft formations to show the aplasia of the sinus maxillaris and frontalis is being given. A aplasia of the sinus maxillaris wasn't found. For the sinus frontalis a aplasia in 11% was found by adults. The one side aplasia was observed by 7.4% and the double-sided by 3.4%, the right-sided aplasia by 4.2% and the left-sided by 3.2%. Patients with cleft formations: The aplasia of the sinus frontalis was found by 55.8%, by the control group in 46.7%. In the age groups 1 to 5 years and 6 to 10 years more double-sided aplasia was found. This result is agree with the results by the control group. The right-sided aplasia is dominant in comparison to the left-sided aplasia in the control group.

[X-rayfilm analysis of the sinus paranasales from cleft patients (in comparison with a healthy group) (author's transl)].

UNLABELLED: A report on 301 x-rayfilms from cleft patients and 120 x-rayfilms of a control group to show the behaviour of the pneumatisation of the maxillar sinus is being given. CONTROL GROUP: The sinus maxillares of the left side by the male and female patients are greater than of the right side. The sinus maxillares are greater by female patients than by male patients. Patients with cleft formation: The sinus maxillares by female patients are significant smaller than the sinus maxillares by the control group. No different are the sinus maxillares by the control group and male with cleft formation patients with the right-sided clefts and female patients with right-sided clefts and on bilateral clefts. The sinus maxillares are of the side of localisation smaller than of the opposite side. By clefts of the primary and secondary palate (L-A-P-clefts) are the sinuses maxillares statistically larger than by clefts of the primary palate (L-A-clefts) and by subtotally and totally clefts of the secondary palate (P-clefts).

[Studies on the state of pneumatization of the sinus maxillaris].

A report on 2940 x-rayfilm observations to show the behaviour of the pneumatisation of the maxillar sinus is beeing given. The greatest extension is reached at the age of 19th to 30 and show deminishing tendenz at later ages. The maxillar sinus is significantly smaller in the nonfemale than in the female. The left maxillar sinus is significantly larger than the right, just like in the feminie, however without statistical significance. 301 cleft proband show a significance smaller maxillar sinus in comparisation to normal persons.

[Combined mass X-ray examinations of the respiratory tract (author's transl)].

2908 persons were investigated by mass chest x-ray combined with mass x-ray of the paranasal sinuses to find respiratory tract diseases. In 412 persons a sinusitis was diagnosed. 212 persons had a positive history, that is headache, cough and/or bronchial secretions, the other 200 persons had a negative history. 91 persons with a negative history and 21 persons with apositive history showed spontaneous remissions. The results of the bacteriological tests and antibiogramms corresponded with the preceding reports. In the investigated population groups a high percentage of new undetected cases of sinusitis was found one year after their previous treatment needing a new treatment. The frequency of undetected sinusitis in adults is often underestimated. Mass chest x-ray examinations should be combined with x-ray examinations of the paranasal sinuses.
