[Resistance patterns of certain Enterobacteriaceae in hospital and outpatients, with particular reference to trimethoprim-sulfamethoxazole (author's transl)].

The relative sensitivities of certain enterobacteriaceae strains obtained from impatient and outpatient material for investigation against trimethoprim-sulf-amethoxazole, ampicillin, cephalothin, gentamicin and tetracycline are reported. The efficacy of the substances tested was very varied, the resistance rates to gentamicin and trimethoprim-sulfamethoxazole being most favorable. Differences in sensitivity could be established between strains from inpatient and outpatient material. Resistance rates were sometimes considerably lower in material for investigation from outpatients. This fact is, among other things, explained by frequent hospital infections with resistant organisms. In addition it could be shown that, by selection of resistant strains in certain areas of a hospital, increases in resistance can appear within a short time.

Trismus resulting from central nervous system lesion.

Three cases of unusual trismus are reported, occurring in patients with lesions of the central nervous system. On the basis of the clinical and electromyographical findings and observation of the course of the trismus this is interpreted as a symptom of a lesion of the brain stem, causing a dis-synergism of the masticatory muscles.

[Trismus, trigeminal motor dyssynergy with brain stem lesions (author's transl)].

Paradox activity of masticatory muscles was observed clinically and electromyographically in 4 patients with brain steem lesions who had trismus. There was no activity in the elevators of the jaw on the side affected during voluntary biting, as if the muscles were paralyzed. There was strong activity of the elevators on the side of the trismus on opening the mouth, inactivity on the unaffected side, or inverse activity appeared on both sides. In view of the trigeminal anesthesia on the side of paradox activation, and the absence of pyramidal signs, a stretch reflex mechanism and abolition of inhibition can not be the only basis for these phenomena; so, a disturbance of bilateral synergism, in the sense of an internuclear lesion, is postulated. In one case of motor and sensory paralysis after the extirpation of a meningioma of the cerebellopontine angle, intensive paradox activity was observed, without trismus.

[Antibody detection in infections with Serratia marcescens (author's transl)].

A report is given on the detection by agglutination and precipitation of antibodies against homologous strains in infections with Serratia marcescens. The results of the investigation indicate that antibody formation is likely if invasive forms are present. The agglutination titers were between 1:40 and 1:640. It can be presumed that, in addition to the patient's antibodies against the O antigen, antibodies are also formed against certain antigens with the character of ferments or toxins.

[Demonstration of specific antibodies in sera of patients with infections caused by aeromonas hydrophila (author's transl)].

According to the formation of specific antibodies against Aeromonas hydrophilia in patients with infections caused by this microorganism the sera of two patients of different clinical picture were investigated. Among the antibodies there could be demonstrated the antihaemolysins against the haemolysin of the monolgous strain, agglutinins against the O-antigen and praecipitins against soluble antigens. The special problems of the technics are described. The results are discussed and interpreted.

[Serratia marcescens infection in intensive care units (author's transl)].

The increased incidence of Serratia marcescens infection at the intensive care unit of the Department of Anaesthetics, General Hospital Altona, was investigated. The properties of this microorganism are described and its role in cross infections is discussed. The frequent occurrence of Serratia marcescens in mixed infections and its tendency to grow on tissue surfaces are pointed out. The presence of Serratia marcescens was demonstrated in 23 of 107 patients treated in the intensive care unit; an infection with Serratia was established in 13 of the 23 cases. Four patients died. As vital functions were severely impaired in these cases death could not be attributed solely to the Serratia infection. Preventive and therapeutic measures are reviewed.
