[Bronchopulmonary foregut malformations with communication to the esophagus].

Congenital abnormal communications between separated pulmonary tissue and the oesophagus are rarities. Only about 50 cases have been reported in the literature. For all different forms the term of bronchopulmonary foregut malformation (BPFM) was first applied by Gerle and his coworkers in 1968. Major symptoms of this condition involved respiratory distress, cough, dyspnea, vomiting and repeated pneumonia. This paper presents reports of two own patients. In both cases was confirmed a bronchopulmonary foregut malformation in the lower right thorax with ectopic main bronchus communicating into the distal oesophagus. According to the literature we describe our own experience and discuss embryologic pathogenesis and surgical consequences for children.

[A change in substitution therapy in patients with congenital adrenogenital syndrome within the scope of surgical interventions].

Stress response during genital surgery was investigated in 18 female patients with CAH. Changes were studied in blood pH and base excess, in serum concentrations of sodium- and potassium ions, in concentrations of 17 OHP in serum and saliva. The following conclusions may be drawn: On the day of operation patients should receive 100 mg Prednisolut per square metre of body surface area i.v., divided in three doses. On postoperative days 1 and 2 the 4 to 6 fold, on postoperative days 3 and 4 the 2 to 3 fold amounts of supplementary doses of hydrocortisone should be administered. Fludrocortisone is substituted with 3-5 mg DCA i.m. only on the day of operation. It is convenient to use a half-isotonic solution of electrolytes with 5% glucose for the infusion therapy. A dose of 25-50 mg Prednisolut i.v. can be added to the substitution therapy before short diagnostic and therapeutic procedures with or without anaesthesia such as endoscopy or change of bandage. Radenarcon (etomidate), used for induction of anesthesia, is contraindicated in patients with CAH.

[Clinically relevant pathogens isolated from blood cultures of inpatient treated children (1972 to 1985)].

Blood cultures are extremely useful in diagnosing various bacteremic diseases in childhood. The results obtained in this study are presented in relation to two periods of equal length (1972-1978, 1979-1985). At the present time there are about 22 relevant isolates from blood cultures per 1000 admitted children and year in the Department of Pediatrics, and about 3 isolates per 1000 admitted children and year in the Department of Pediatric Surgery, respectively. From newborns we isolated most frequently E. coli, Staph. aureus, B-Streptococci, Pseudomonas aeruginosa, Klebsiella pneumoniae, and yeasts. From children beyond the first month of life Haemophilus influenzae, Streptococcus pneumoniae, other streptococci, Neisseria meningitidis, and Staph. aureus were the most frequent identified etiologic agents. The main factors influencing the spectrum of agents causing bacteremia are: age of patients, status of hospitals, and applicated diagnostic and therapeutic procedures.

[Pathohistologic studies of the upper esophageal blind pouch--a contribution to the discussion of the cause of anastomotic insufficiency following surgically treated esophageal atresia].

The pathological and anatomical findings obtained in studies of the upper oesophageal blind pouch are described for ten cases of oesophageal atresia where no surgical operations were performed. Figuring prominently in this conjunction are both aplasias and hypoplasias of muscular layers with deficiencies and textural disturbances as well as reductions of intramural ganglia and glands. These particular results are discussed as causes of anastomotic insufficiency after surgical operation for oesophageal atresia. Communications reporting comparable results were not found in literature. From an interpretation of findings it is obvious that the surgical procedure cannot, in many cases, be blamed for anastomotic insufficiency, but that the latter appears to be due essentially to textural disturbances in the oesophageal blind pouches. Also, this would explain why it was not, in the last couple of years, possible to achieve a further reduction in the postoperative lethality rate.

[Orchitis and epididymitis caused by Salmonella cholerae suis in a premature infant].

It is reported on a premature infant who fell ill with an orchitis and epididymitis by Salmonella cholerae suis in the fourth week of life. The proof of the germs was carried out by means of two blood cultures as well as in the smear from the periorchium. The most important informations from literature concerning this subject are briefly reviewed.

Pneumococcal infections during childhood: serotyping of pneumococcal strains from forty-six children.

The results of serotyping of forty-six strains of pneumococci isolated from children aged 3/12 to 14 9/12 years and diagnosed as having pneumonia, meningitis, primary peritonitis, otitis media, lymphadenitis, osteomyelitis, bacteraemia and conjunctivitis are presented. The results of serotyping and the frequency distribution of the detected serotypes were compared to the particular diagnoses established and the age at which the subjects involved had become ill. Questions of epidemiology and possibilities of immunoprophylaxis are discussed. Finally, the occurrence of pneumococci that are resistant to antibiotic agents are discussed since an isolated strain was found to show reduced susceptibility to penicillin G.
