Description of 23 patients (21 women, 2 men) with an average age of 36.6 (19--68) years, who were hypokalemic during 6.5 years on the average (range 1/2--16 years). The cause of the potassium depletion was malnutrition (anorexia nervosa, vomiting) and/or abuse of laxatives and/or diuretics. With increasing duration of potassium depletion renal function deteriorated; in two cases terminal renal failure developed. Histology of the kidneys (9 cases) showed the picture of chronic abacterial interstitial nephritis. Urinalysis was negative or non-specific. The blood pressure levels were normal or low, hypertensive values being exceptional. Aside of hypokalemia a tendency to hyponatriemia, hypochloremia and metabolic alcalosis was observed, the latter turning into hypokalemic normochloremic acidosis with advancing renal insufficiency. Plasma renin activity and aldosterone concentration or excretion frequently were elevated, but no close correlation was found between these parameters or with the blood pressure. Bacterial infection of the urinary tract occured, if at all, in the late phase and seems to be complication rather than the cause of the kidney disease. The discussion of other possible pathogenetic factors leads to the conclusion that the term "chronic kaliopenic nephropathy" is justified. Some diagnostic and therapeutic consequences are mentioned.

A 13-year-old girl with a ten-year history of lymphoblastic leukemia and several central nervous system (CNS) relapses developed a bone marrow relapse and accelerated CNS leukemia. Following treatment with CNS radiation and intravenous chemotherapy, she developed fever, pancytopenia, headache, and vomiting. Her neurological function deteriorated and she died on the 20th hospital day. Multiple CSF examinations failed to disclose either leukemic cells or organisms. Blood cultures obtained from a Broviac catheter yielded Micrococcus species. Postmortem examination showed meningoependymitis with intracellular coccal organisms. The pathology of this infection resembles intracranial Whipple's disease. Intracranial intracellular bacterial infection should be excluded in the infectious complications in the immunocompromised host.

A 14-year-old girl was hospitalized with fever, jaundice, vomiting and right sided abdominal pain. A laparotomy was performed because of muscular defence and ascites. There was a mass of enlarged red and blue colored lymph nodes in the mesentery of the lower ileum loop. The histologic diagnosis of HNL without granulocytic infiltration was made. A septic-toxic shock developed after surgery. Respiratory insufficiency necessitated the use of a respirator, and acute renal failure with oliguria made hemodialysis necessary. The dramatic clinical course of the illness and the localization of the affected lymph nodes in the abdomen are unusual for an HNL; the lack of granulocytic infiltration contradicts the clinical picture of a bacterial infection. Neither a bacterial nor a viral pathogen could be found. However, the patient had been treated with antibiotics before.

Male patients with the X-linked lymphoproliferative syndrome (XLP) have an inherited immune deficiency to Epstein-Barr virus (EBV) infection that results in fatal infectious mononucleosis (IM), acquired hypogammaglobulinemia- or agammaglobulinemia, virus-associated hemophagocytic syndrome, and non-Hodgkin's malignant lymphoma (ML). A clinicopathologic analysis of 17 patients with XLP who developed ML was performed. The median age of the patients at the time of diagnosis was 4.0 years (range, 2-19 years). The median overall survival was 12 months (range, 1-216 months). Eight patients had maternally related male relatives with ML. Other phenotypes of XLP were documented in male relatives of the remaining nine patients. Common presenting symptoms were fever, nausea, vomiting, and abdominal pain. Nine patients had "B" symptoms. All ML occurred at extranodal sites. The intestines, most commonly ileocecal, were involved in 76.5% of the cases. Thirteen patients had localized disease (Stages I and II) and four patients had advanced disease (Stages III and IV). A diffuse histologic pattern of growth was observed in all cases. The distribution of histologic subtypes included small noncleaved (41.2%), large noncleaved (17.6%), immunoblastic (17.6%), small cleaved or mixed cell (11.8%), and unclassifiable (5.9%) ML. Surgical resection, radiation therapy, and chemotherapy resulted in disease-free survivals of up to 192 months in eight patients (median 114 months; range, 12-192 months). Eight of 17 patients (47%) are still alive. A median survival of only 6.0 months (range, 1-12 months) was observed in the nine patients who died. No residual ML was found at autopsy. The small noncleaved subtype had an adverse prognosis (seven of nine deaths versus one of eight survivors; P less than 0.05). Bacterial infection was the major cause of death (seven of nine patients). Characteristics that distinguish ML in XLP from other ML include a maternal family history of XLP, early age of onset, acquired hypogammaglobulinemia, post-EBV infection, and ileocecal involvement.

We studied a selected series of febrile infants (N = 201) in an attempt to prospectively identify risk factors for bacteremia. Infants with fever less than 39.4 C, vomiting and diarrhea, croup, or viral exanthem or enanthem were not included. Twenty-one infants (9.5%) had positive blood cultures despite the initial judgment of their physician that only viral illness or localized bacterial infection existed. WBC count of more than 15,000 correlated with bacteremia, with a sensitivity of 0.71 and a specificity of 0.73. Extensive multivariate linear regression analysis attempting to increase predictive values was completed. The combination of fever higher than 39.4 C present for more than 12 hours and absolute polymorphonuclear count of more than 9,000 cells/mm3 had a sensitivity of 0.62 and a specificity of 0.78 for bacteremia. Descriptive statistics for groups with and without bacteremia are summarized. We have defined prospectively a population of infants with a high probability of bacteremia and a lower probability of viral illness. Identification of such a group is useful to the emergency physician because early antibiotic therapy may lessen morbidity and mortality. We conclude that an easily obtained data base may be useful in the prospective identification of those at risk for bacteremia.

Bacterial infections are frequent events in premature and newborn infants. The reason is a defective specific and nonspecific defence of bacterial organisms. Some immunoglobulins like IgM and IgA including secretory IgA are absent. Premature infants also show a decreased level of IgG. Cellular immunity is anatomically intact but functionally defective. A number of complement factors are lacking, the activation of the alternative pathway is impaired. Newborn infants with perinatal problems like asphyxia or difficult delivery, show defects of leucocyte function like decreased deformability, defective chemotaxis and defective killing of ingested bacteria. Certain diseases, like hypoxia and malformations of immature organ functions in this age group (decreased acid production in the stomach), facilitate bacterial colonization of surface epithelia and the invasion of tissues. Consequences of these pathogenetic mechanisms are an unimpaired propagation of bacterial organisms into the blood and meninges without localization of the infecting organisms at the entry site. Bacterial meningitis is not considered a separate disease entity but a complication of bacteremia and sepsis. Clinical symptoms are nonspecific at the onset of the infection. Fever is frequently absent; decreased appetite, vomiting, a bloated abdomen, diarrhea, tachycardia, tachypnea are early signs of a bacterial infection, a grey mottled appearance, cyanosis, jaundice, petechiae, apneic spells, seizure activity and a metabolic acidosis are symptoms of advanced infection. Successful treatment at this stage is often not possible. Every sign of a decreased well being of a newborn of premature infant warrants laboratory and bacteriologic work up for septicemia.(ABSTRACT TRUNCATED AT 250 WORDS)

Proventricular dilatation was diagnosed in 16 psittacine birds. Signs included anorexia, lethargy, weight loss, and intermittent vomiting. The proventriculus in all birds was thin-walled and impacted with ingesta and occupied most of the body cavity. Microscopic changes in the proventriculus varied from none to an infiltration of lymphocytes, macrophages, and heterophils. There was no evidence of viral or bacterial infection or lead toxicity.

A 29-year-old white female developed fever, vomiting, diarrhea, and hypovolemic shock. Twenty-four hours after resection of intraperitoneal adhesions she had granulocytopenia and leukopenia with a marked "left shift"; a bone marrow aspirate was interpreted as showing acute non-lymphocytic leukemia. The clinical presentation made this diagnosis unlikely and the subsequent course indicated that this was a reaction to bacterial infection.

The authors report on a case of sepsis due to E. coli in a newborn baby with galactose intolerance. The immature immunological state of the newborn child in combination with a disorder of galactose metabolism obviously favour the development of bacterial infections. Galactose-free formulas should be applied quickly together with an adequate antibiotic therapy in the case of newborn babies with suspected bacterial infection. The prognosis may be influenced favourably by early clarification of the cause of severe impairment including jaundice, vomiting, loss of weight and somnolence in the first three weeks of life.

A prospective study was performed to estimate the frequency of gastroenteritis due to Yersinia enterocolitica in Montreal children and their families. Evidence of bacterial infection was correlated with clinical features and serologic responses. YE was isolated from the stools of 181 (index cases) of 6,364 children with gastroenteritis over a 15-month period; Salmonella was isolated from 280 and Shigella from 68. Median ages were 24, 30, and 41 months, respectively. All but 18 YE isolates were biotype 4, serotype 0:3. YE was not found in the stools of 545 children without gastrointestinal symptoms. Clinical manifestations of the index cases with YE biotype 4, serotype 0:3 (n = 57) included diarrhea (98%), fever (88%), abdominal pain (64.5%), and vomiting (38.5%) with mean durations of 14, 3.9, 7.7, and 2.4 days, respectively. The duration of excretion of YE in the stool ranged from 14 to 97 days (mean 42). Spread of YE occurred in 27 of 57 families studied, involving 15 of 41 children and 19 of 117 adult contacts; approximately one-third of infected contacts developed diarrhea. Agglutination titers of greater than or equal to 200 were demonstrated in all index cases infected with serotype 0:3, with the exception of two very young infants. YE is a frequent cause of bacterial gastroenteritis in Montreal children. The illness is characterized by persistent diarrhea and abdominal pain, prolonged YE excretion in the stools, and moderate communicability.
