[Studies reagarding the bioavailability of oxacillin from preconditioned powders]

Previous studies have pointed out a good antimicrobial activity of two oxacillin salts--DBED--oxacillin and calcic oxacillin--which were conditioned as "preconditioned powders" for oral suspensions. The above mentioned preparations were followed up by administration to animals, and similar seric concentrations in DBED oxacillin and sodic oxacillin (with the difference that insoluble salts present a long-time activity) were pointed out.

[Study of deformities of the human pelvis, using the tensiometric method (experimental research)]

The authors present the result of their experimental studies with the tensiometric method performed on human renal basins with the tensiometric method, under different conditions of stress. The studies have been based on the principle of recording microdeformations of basins under determined amounts of stress, and they have demonstrated the proportionality between the stress and the deformation as being a direct one. The most stressed areas have been evidenced, when transversal and antero-posterior compression was applied, and the mechanism is explained, of the rupture of the basins in relation with the concentration of the tension that have developed in a predilect way in certain areas.

[Complications of surgery of cancer of the colon]

In the paper a systematic analysis is carried out of postoperative complications of colon surgery, 118 patients had complications, out of a total of 400 interventions on the colon. The complications are studied in relation with the time of their occurence and the localization of the neoplastic process, as well as from the point of view of the influence exerted by age and the "background" of the patients. A review is also made of the therapeutic attitudes required by the various complications, of the results obtained and finally a detailed analysis is presented of the causes that led to death of operated patients.

[Pancreatic fistulas]

Based on 17 observations the authors review the major etiopathogenic, evolutive, clinical and therapeutic aspects of pancreatic fistulae. In 14 cases the cure was achieved by medical treatment while surgery was resorted to in only three cases. The medical measures are discussed, as well as the indications for surgical treatment.

[Treatment of supramalleolar open fractures by means of centro-medullary osteosynthesis of the fibula]

The study is concerned with 11 cases of open supra-malleolar fractures involving both bones. The tibial fracture was of the comminutive type, with a large number of small fragments allowing an exteriorization of the proximal end or telescoping of the ends with consecutive loss of the axis. Due to a difficult synthesis of the tibial bone synthesis of the peroneum with a thick rod or with a brooch was performed, recovering the length of the lever and allowing to de-telescope the tibial focus, to recover the normal length and a corresponding axis. Since in all the treated cases consolidation was achieved over a duration of 5 months, the advantage is stressed, of the procedure which, solving indirectly the fracture, protects the tibial focus, already poorly irrigated and susceptible to pseudarthrosis in thi;s type of location.

[Surgical reoperation after vagotomy]

In 39 cases of re-interventions carried out after vagotomy (of which 31 were patients hospitalized in the Clinic and represent 8,6% of the total 358 vagotomies performed), the experience, the viewpoints and the recommendations of the authors are presented. Early re-interventions were necessayr because of complications which are common to abdominal surgery and only in a much lower degree to accidents that can be attributed to vagotomy or the associated intervention. Late re-interventions (26 cases) were necessary in 20 cases for ulcer recidives (13 for vagotomies performed in the Clinic and 7 for vagotomies performed in other units) while late-re-interventions for dumping syndrome, cholelythiasis, etc. represented only isolated cases in these statistics.

[Surgical rehabilitation of nonfunctioning bilio-digestive shunts]

The authors consider the internal biliary derivations as a choice procedure for the resolution of various pathological conditions of the biliary pathways and of the pancreas. They are based on the experience accumulated in the course of a total of 416 derivations performed in the last 10 years. The confrontation with particular problems raised by 40 re-interventions for failure of internal biliary derivations has determined an analysis of causes, clinical manifestations and possibilities to solve the disturbances. Categories are discussed, in which these patients can be classified and clinical observations are presented, in connection with the etiopathogeny of the non-functioning of the derivations. Possibilities are also presented for the resolution of the problems in each particular case. Two technical possibilities are presented for the correction of non-functioning biliary-digestive anastomoses, by performing bilio-biliary anastomoses.

[An autochthonous case of amebic hepatic abscess with pleural dissemination]

The present paper reports on the first autochtonous case of amoebic hepatic abscess in Romania in a patient in which the epidemiologic survey showed that there had been no possible import infection. The amoebic abscess was located in the superoexternal area of the right hepatic lobe. Subsequently a major complication developed: a tendency to pleuropulmonary invasion with the formation of fluid in the right pleural cavity. The diagnosis, suggested by the aspect of the abscess cavity, was established by the presence of the parasite in the flaky pleural exudate obtained by puncture, by cultures in Loeffler medium and by serum immunofluorescence. The abscess was evacuated surgically and a specific treatment with Chloroquine and Metronidazol combined with antibiotics and a symptomatic medication was prescribed. The patient recovered and was discharged 51 days after surgery.

A new nephritogenic streptococcus

A local milk-borne outbreak of 85 cases of sore throat with cervical lymphadenitis, a third of whom later developed acute glomerulonephritis as a complication, is described. Renal involvement was shown by Volhard's criteria, filtered fraction data and renal biopsy findings. From lymph-node biopsies from patients, from the pharyngeal exudate of patients and carriers, and from three samples of cow's milk, 16 strains of beta-haemolytic streptococci of Lancefield group C, type zooepidemicus subtype lactose-positive, were isolated.

The aetiological role of the streptococcus isolated in this outbreak was confirmed by autoserodiagnosis (precipitation tests with Lancefield's antigens and patients' sera) which in this case proved more valuable than antistreptolysin-O titration as evidence of infection.

Two of the 85 patients, 7 months after the acute phase of illness, show nephrotic oedema and hypertension as chronic sequelae.

We are pleased to express our gratitude to Dr M. T. Parker and Dr W. R. Maxted for much advice, and confirmation of our serological and biochemical findings.
