A 3-week-old child arrived at the emergency room with the concurrent onset of sepsis and methemoglobinemia associated with diarrhea. Subsequently, the child had two recurrent episodes of methemoglobinemia with re-exacerbations of his diarrhea. Possible causes and associations of methemoglobinemia are presented: particular emphasis is placed on the early recognition and rapid diagnosis of this life-threatening condition.

In a series of 46 patients with localized gastric cancer treated at Massachusetts General Hospital, problems with excessive acute or chronic toxicity due to combination treatment with irradiation (XRT) and chemotherapy (CT) were not seen. Forty of the 46 received combined treatment with 2 regimens: 1) Irradiation plus concomitant 3 days of 5-FU followed by maintenance 5-FU or combined drugs--26 patients; 2) In the other 14 patients, the sequence of irradiation and chemotherapy was altered. A single course of combined drug chemotherapy was given prior to irradiation and 5-6 additional courses were administered after completion of XRT (CT-XRT-CT). The drug combination was initially 5-FU-BCNU but this was changed to FAM (5-FU, Adriamycin, Mitomycin C). Irradiation was delivered to tightly contoured portals using shaped blocks to spare as much small bowel, kidney and marrow as possible while giving 4500-5200 rad in 25 to 29 fractions over 5 to 6 weeks. In this series, there were no cases of septicemia or any deaths related to treatment. A 3 year survival rate of about 20% was achieved for the total group of patients and 43% in the group with resection but at high risk for later failure. Our inability to improve these numbers is undoubtedly a result of dose limitations with external beam irradiation combined with a systemic failure problem. When irradiation is combined with surgical resection of all or a majority of tumor, both survival and local control appear to be better than in the unresected patient group. Only 4 of 29 patients (14%) with curative resection, or resection but residual disease, had later evidence of failure within the irradiation field as opposed to 6 of 9 or 66% in the group with unresectable disease.

A 3-month-old boy was admitted with failure to thrive and persistent fevers. During a 4 month hospitalization for treatment of suspected sepsis, persistent purulent nasal discharge developed. Biopsies of his nasal mucosa on 3 separate occasions disclosed thinned respiratory epithelium and a complete absence of cilia when examined by electron microscopy (EM). Despite an initial granulocytopenia and a wide range in T-cell numbers, he did not show any evidence of lower respiratory tract infection. A tracheal biopsy process for EM demonstrated normal ciliated epithelium. This patient appears to have an unrecognized syndrome of normal tracheal cilia but absent nasal cilia.

A 3 1/2-year-old boy with primary staphylococcal septicemia presented with elevated cerebrospinal fluid protein and pleocytosis. Serial computerized tomography examinations revealed the development of an intracranial lesion suggestive of an early infectious process. All cultures of cerebrospinal fluid taken before and after antibiotic treatment revealed no growth. Although no focal neurological findings evolved, both clinical and radiologic abnormalities resolved with antibiotic therapy. Computerized tomography can provide a means to diagnose cerebritis and to evaluate therapeutic response.

A 3 day old neonate with septicemia and meningitis due to Plesiomonas shigelloides is described. We could not detect the source of this infection. The patient was treated with cefotaxime and survived without sequelae. Nine previously reported cases with this infection were reviewed.

A 3-week-old boy presented with severe thrombocytopenia and recurrent infections. He was subsequently found to have Wiskott-Aldrich Syndrome, a rare X-linked disorder. Splenectomy was performed and he died of post-splenectomy sepsis despite prophylactic antibiotic therapy. This is the first recorded case in the English-speaking Caribbean.

Haemophilus influenzae type b, a causative agent of bacterial sepsis and meningitis in young children, contains a single superoxide dismutase (SOD), a cytoplasmic MnSOD. To study the role of this enzyme, a chromosomal sodA::lacZ mutant (M-2) was constructed. M-2 had an increased sensitivity towards oxygen and the redox-active agent paraquat. A 3.4-fold increase in sodA-lacZ expression was found in M-2 grown with oxygen supply rates between 3 and 36 mmol of O2/liter/h. In similar experiments with the wild type, assaying SodA activity, a 3.1-fold increase was found. Both the wild type and M-2 grew best at the lowest oxygen supply rate tested, consistent with the notion that H. influenzae prefers a more anaerobic environment. In the infant rat model of infection, the ability of M-2 to colonize the nasopharynx was found to be impaired, but its ability to cause invasive disease was unaffected. This suggests that after invasion, the growth disadvantage imposed by a SodA- phenotype is not limiting.

A 3-day-old female Pinto was admitted with profuse watery diarrhea and severe hypovolemic shock. After 1 week of intensive care, the foal developed seizures associated with profound serum electrolyte abnormalities suggestive of hypoadrenocorticism. Treatment with prednisone and isotonic saline (0.9% NaCl) solution led to prompt clinical response. Premature withdrawal of prednisone resulted in relapse of clinical signs. A diagnosis of adrenal insufficiency was made on the basis of clinical signs, electrolyte abnormalities, low baseline cortisol concentration, and lack of response to administration of exogenous adrenocorticotropin. Two months later, adrenocortical function was normal and the foal was doing well clinically. Clinical signs of acute adrenal insufficiency in neonatal foals can be confused with other conditions, such as septicemia, enteritis, and ruptured urinary bladder. A persistently low serum sodium-to-potassium ratio associated with CNS malfunction should warrant investigation of adrenal gland function. Acute hypoadrenocorticism in foals may be reversible.

A 3-yr-old female patient exhibited interleukin 12 (IL-12) deficiency that was associated with recurrent episodes of pneumococcal pneumonia with sepsis and other infections in the absence of fevers. The patient's peripheral blood mononuclear cells (PBMCs) exhibited normal proliferative responses to antigens. Immune responses, including in vivo production of antibodies to diphtheria, tetanus, or pneumococcal antigens, were normal. Ig levels and B cell and T cell phenotypes were also normal. In contrast, IL-12 p70 heterodimer production was undetectable by using supernatants of the patient's stimulated PBMCs when compared with control cells treated similarly. Although present, interferon gamma (IFN-gamma) was reduced. The addition of recombinant IFN-gamma to control cells enhanced the production of IL-12 by up to sixfold. By contrast, IL-12 was undetectable in supernatants of the patient's cells in the presence of recombinant IFN-gamma. IL-12 p40 subunit mRNA by using the patient's PBMCs after stimulation with Staphylococcus aureus Cowan strain 1 or lipopolysaccharide was also undetectable by reverse transcription-PCR when compared with control cells. Production of IL-2, IL-6, tumor necrosis factor alpha, or IFN-gamma of the patient's PBMCs after appropriate stimulation was observed. This patient has either a defect in Staphylococcus aureus Cowan strain 1-lipopolysaccharide- or staphylococcal enterotoxin A-induced signaling pathways for the activation of IL-12 p40 gene expression, or an abnormality in the IL-12 p40 gene itself.

A 3-week-old male infant, born full term without complication, developed septic arthritis of his left shoulder. His joint fluid, blood, and bone marrow were all positive for Escherichia coli. Urinalysis demonstrated pyuria. Urine culture obtained after one dose of ceftriaxone and several doses of nafcillin was negative. Work-up revealed a refluxing, right single ectopic ureter with severe hydroureteronephrosis and a non-functioning ipsilateral kidney. After appropriate management of the musculoskeletal infection, he underwent a right nephroureterectomy. Coliform septic arthritis is exceedingly rare in children, with only a few cases reported. We report the first case of septic arthritis with anomalous genitourinary tract development as the source of bacterial seeding. This report re-emphasizes the need to screen the urinary tract in all cases of pediatric gram-negative sepsis.
