Plasma cortisol levels and their response to .25 mg synthetic A.C.T.H. (Cortrosyn) were studied in 26 septic patients. Four (15.4%) of these patients appeared to have greatly increased adrenocortical activity with plasma cortisol levels averaging 65.4 +/- 14.8 microgram/dl (normal = 8-18 microgram/dl. All four of these patients were agonal and died within five days. Seventeen (65.4%) of these 26 patients appeared to have an appropriate adrenocortical response to severe infection in that their plasma cortisol levels increased (averaging 19.2 +/- 6.0 microngram/dl) following synthetic A.C.T.H. The remaining five patients, who constituted 19.2% of the 26 patients studied, appeared to have some impairment of adrenocortical function. In spite of severe bacterial infections and no history to support Addison's disease, their plasma cortisol levels (averaging 13.8 +/- 3.3 microgram/dl) were not increased above normal and their response to Cortrosyn was much less than would be expected; the increase in plasma cortisol levels in these patients following the synthetic A.C.T.H. averaged 1.1 +/- 3.6 microgram/dl. It is reemphasized that patients with severe sepsis who are not responding adequately to standard therapy should be suspected of having adrenocortical insufficiency and treated accordingly.
Acute bacterial infections are a common cause of pediatric visits to the emergency department. The diagnosis and treatment of pharyngitis, otitis media, pneumonia, urinary tract infection, acute bacterial lymphadenitis and gastroenteritis are reviewed. The authors propose the use of a limited number of antibiotic agents including penicillin, ampicillin, erythromycin, lincomycin, cephalexin, a sulfonamide and tetracycline to improve efficiency and quality of care and to allow physicians to become familar with the drugs' characteristics, indications, dosage and side effects.

Treatment of bacterial infections in pregnancy requires an understanding of the unique problems related to the administration of antibacterial agents to pregnant women. The clinician must be aware not only of the antibiotic-associated untoward effects which may develop in the mother, but also of the possibility that adverse reactions may occur in the fetus. Precise knowledge of the microbial aetiology of those infections which occur during pregnancy and an understanding of the intricacies of antibiotic administration to pregnant women will assure the greatest likelihood that bacterial infections in pregnancy will be effectively, and safely, treated.
Consecutive newborn autopsy cases were divided into infected and noninfected groups on the basis of pathologic findings and cultures, and were compared to a concomitant consecutive group of neonatal survivors with proven bacterial sepsis. Newborns dying with bacterial infection often demonstrated leukopenia, neutropenia, and thrombocytopenia, usually associated with normal bone marrow cell production. Those with nonfatal sepsis frequently had neutrophilia with an increase in absolute band counts. Of infected newborns 80% showed one or more hematologic abnormalities as did 43% of newborns dying without bacterial infection. Of newborns dying with bacterial infection 13% had no hematologic abnormality. Blood cultures were negative in 18% (seven) of the infants dying with bacterial infection. Abnormalities of the white blood cell, differential and platelet counts are not invariably specific for bacterial infection nor do normal values adequately exclude it. Blood cultures may be negative in newborns dying with significant foci of bacterial infection.
A case with prolonged bacterial infection accompanied by an abnormal serum protein which migrated in the post-gamma region on electrophoresis is presented. The abnormal protein was identified as IgG with gamma-type light chain moiety. The patient suffered from prolonged pneumonia and cholecystitis, Bone marrow aspiration and skeletal x-rays did not indicate multiple myeloma.
A bacterial infection was considered to be responsible for provoking or containing episodes of thrombocytopenia in 5 patients with chronic idiopathic thrombocytopenic purpura (ITP). In 3 patients the course of the disease was continuous and in 2 of them remission was attained after eradication of the infection. In the other 2 patients the course was intermittent and a number of relapses was provoked by the infection. The possible causal connection of chronic ITP and bacterial infections is briefly discussed.
Bacterial infections of the pancreas and bacteremia may occur during episodes of pancreatitis. Detection of bacterial infections of the pancreas in the past has required laparotomy. The present study was undertaken to determine whether bacterial infection of the pancreas occurred during nonsuppurative pancreatitis. During endoscopic cannulation of the main pancreatic duct, secretin was administered intravenously and pancreatic juice aspirated from within the duct was cultured. Bacterial infections were detected in 11 of 35 patients with pancreatitis and 3 of 5 with pancreatic cancer. The pancreatic juice was sterile in 25 controls. Cultures from the common bile duct in 9 controls were also sterile whereas 4 of 6 with pancreatitis showed infected bile. The infecting organisms were principally gram-negative and the infections were usually polymicrobial. Antibiotics, where used, successfully eradicated the infecting organisms but did not appear to affect the patient's clinical course.
