A case of cutaneous myiasis is reported, caused by larvae of the fly Dermatobia hominis, found in South and Central America where the disease was contracted during a journey. With the spread of air travel such parasites may be carried to Europe and elsewhere. There are also fly species in Central Europe whose larvae could potentially cause myiasis.
Thrombocyte levels of patients undergoing open heart surgery were studied to compare effects of a bubble with a membrane oxygenator. Loss of platelets, which is not explained by hemodilution, is smaller in membrane oxygenation and normal level of platelets is readily established postoperatively compared to conventional bubble oxygenation.
This study describes a family with gastrointestinal adenomatous polyposis. One member had symptoms of Peutz-Jeghers disease with histologically typical polyps besides those of the adenomatous type. In cases of clinical gastrointestinal polyposis the exact histologic diagnosis of an endoscopic sample is mandatory. The benign e.g. non adenomatous, finding compels one to auxiously care for those patients and to prophylactically examine all members of the patients family, while adenomatosis implies prophylactic surgery. The indications are discussed.
Sixty-two cases of mesenteric panniculitis collected from the literature and six cases treated by the authors are reviewed. Symptomatology, pathology, treatment, and outcome of this disorder are discussed. It seems that mesenteric panniculitis is a well established clinical entity of unknown etiology, with a benign course and favourable outcome. Radical surgical treatment is not advised. The sole surgical intervention advocated would be deviation of the gastrointestinal tract in patients with symptoms of obstruction.
Five different membrane oxygenator devices were tested in dogs. The following criteria were compared: operating reliability, gas exchange rates, and changes of the mean erythrocyte volume.

The purpose of this study was to analyze the function of the superficial muscles of the anterolateral wall of the abdomen in dorsal decubitus by an original technique: electromyocartography. This technique attempts to monitor the individual or inter-subjective variations that complicate quantitative analysis of the overall electromyogram with integration of action potentials. It is shown that relative quantification of the areas explored with respect to the most active area considerably improves the consistency of the results. The most dependable electrode locations for the analysis of the abdominal muscles are determined. From a functional point of view: The rectus abdominis is active in flexion of the cranial portion of the trunk, either alone or in combination with right or left rotation of the trunk. Its activity is less, and predominates in the distal portion of the muscle, in flexion of the caudal portion of the trunk in combination with a 15 degree flexion of the hips. The obliquus internus abdominis, which can be explored only in a single area, is especially active in rotation. The obliquus externus abdominis plays a major role in stabilizing the pelvis when the lower limbs are involved in the movement of the trunk.
The pattern of use of antimicrobial agents in 1,700 patients hospitalized in a medical ward at the Hadassah University Hospital, Jerusalem, during 1969--72, is analyzed. Penicillins comprised 56%, tetracyclines 11%, streptomycin 9% and cephalosporins 3% of the total antimicrobial exposures. Ampicillin was given to 20% of the patient population. The use of tetracyclines and chloramphenicol fell steadily from 1969 to 1972. Fifty-five percent of the recipients of antimicrobial drugs received only one agent, 19% had concomitant therapy with several agents and the remainder received multiple antimicrobial drugs sequentially. One hundred and ten patients (6.5%) developed adverse reactions; the most common being rash and gastrointestinal reactions. Only two of the reactions were classified as causing major morbidity.
