Cases of pediatric nonenvironmental hypothermia are uncommon. When presenting to the emergency department, these patients are often evaluated for possible sepsis/shock, brain tumors, endocrine disorders, and drug ingestions. We report a case of a 5-year-old girl who presented to the pediatric emergency department on two occasions with hypothermia and lethargy. She was found to have an unusual cause of her symptoms: episodic spontaneous hypothermia with hyperhidrosis.

A free-living, female Grevy's zebra (Equus grevyi) foal was found lethargic, lame, with swollen joints, pyrexia, and urine dripping from the umbilicus. It died 2 days later despite intensive care. Gross examination revealed patent urachus and suppurative arthritis. Swabs were taken from the joints, the patent urachus, and urine for bacteriology. The dominant isolate was Escherichia coli. The joint infection was probably secondary to septicemia, resulting from the patent urachus. To our knowledge, this is the first report of neonatal patent urachus in a wild equid.

We report two infants with an inborn error of cobalamin (vitamin B(12)) metabolism whose clinical presentation in the first month of life strongly suggested bacterial or viral sepsis. The absence of any acute metabolic derangement (acidosis, hyperammonemia, hypoglycemia, or ketosis) in association with clinical features suggesting sepsis (lethargy, obtundation) could impede the correct diagnosis of cobalamin C (cblC) disorder. In addition, this is the first documentation of cerebrospinal fluid hyperhomocysteinemia in cblC defect that was highly increased and is likely to be associated with neurotoxicity in cblC patients.

During August 2001, a syndrome characterized by acute lethargy and dyspnea was observed in a population of 45 lorikeets and lories in an open-air zoologic exhibit. The first death occurred on August 10, and within the next 12 days, nine more birds died (22% mortality rate). Hepatomegaly, reddening and congestion of the lungs, and injection of the serosal surface of the intestines were the common gross findings. Histologic changes, including fibrinonecrotic hepatitis and splenitis, bacterial emboli (liver, spleen, lung, kidney, proventriculus), pulmonary congestion and hemorrhage, and enteritis, were indicative of an acute, overwhelming bacterial septicemia. Salmonella typhimurium, with the same antibiogram, was isolated from four birds. Several birds had attacked and killed a snake on July 24, and Salmonella serogroup B (untypeable) was isolated from intestine and kidney samples of a garter snake caught in the open-air exhibit on August 28. Salmonella was also isolated from environmental samples of the exhibit but not from food preparation areas. After antimicrobial therapy, Salmonella spp. was not isolated from the surviving birds. The source of Salmonella in this outbreak remains unknown, but infection either directly or indirectly from snakes in the exhibit is possible. Contact between captive psittacine populations and reptiles should be avoided to prevent the risk of salmonellosis.

There is a paucity of data regarding predictive values and likelihood ratios of clinical signs for the diagnosis of late onset neonatal septicemia. This study aimed to determine these parameters in a prospective fashion, deriving a score by combining the most useful signs and determining the diagnostic utility of the score. All neonates admitted to a neonatal unit over a 1-year period were monitored for the occurrence of 16 pre-defined clinical signs. Symptomatic episodes (105 episodes in 80 neonates) were investigated for sepsis, and diagnosed as definite sepsis (n = 30), most probable sepsis (n = 17), and no sepsis (n = 58). Seven clinical signs (grunting, abdominal distension, increased pre-feed aspirates, tachycardia, hyperthermia, chest retractions, and lethargy) had positive likelihood ratios (PLR) greater than 1, and were combined to make a composite score. When a weighted clinical score (WCS) was used to diagnose definite sepsis, a cut-off score of 2 gave the best positive predictive value (PPV) and PLR (52 per cent and 2.65, respectively), and a cut-off score of 1 gave the best negative predictive value (NPV) and negative likelihood ratio (NLR) (85 per cent and 0.44, respectively). A cut-off score of 2 had a PPV of 65 per cent for definite and/or probable sepsis. In conclusion, physicians who attempt to make a diagnosis of neonatal sepsis on purely clinical grounds can use a seven-item weighted clinical score.

Left ventricular (LV) outflow tract-right atrial (RA) communication associated with bacterial endocarditis is described in a 6-year-old intact male Great Pyrenees dog with a 4- to 5-day history of fever, lethargy, weight loss, severe regenerative anemia, and asplenia. Typical vegetative mural endocardial lesions were observed grossly. Histologic evaluation revealed small gram-negative coccobacilli that were consistent with Bordetella avium-like organisms. These bacteria were associated with severe endocardial inflammation characterized by neutrophilic infiltration, extensive necrosis of endocardium, and fibrin deposition. LV-RA shunt (Gerbode defect) is a rare cardiac defect in humans that can be either congenital or, more rarely, secondary to septic endocarditis, valve replacement procedures, or thoracic trauma. B. avium-like organisms causing septicemia and endocarditis in immunocompromised and asplenic human patients have been described. To our knowledge, no previous descriptions of Gerbode defect associated with bacterial endocarditis in domestic animals have been reported in veterinary literature.

The nonpoliovirus enteroviruses commonly infect newborns, with consequences ranging from asymptomatic infection and benign illness, to severe, life-threatening disease. Frequently occurring symptoms include fever, irritability, lethargy, anorexia, and rash. Although most illnesses are mild, severe disease develops in a subset of newborns infected in the first 2 weeks of life. Severe disease may consist of sepsis, meningoencephalitis, myocarditis, pneumonia, hepatitis, and/or coagulopathy. Substantial mortality rates have been reported, and long-term sequelae may occur among survivors. Risk factors and clinical features associated with severe disease include absence of neutralizing antibody to the infecting serotype, maternal illness prior to or at delivery, prematurity, illness onset within the first few days of life, multiorgan disease, severe hepatitis, positive serum viral culture, and specific infecting serotype (e.g. group B coxsackieviruses and echovirus 11). Whereas the mainstay of diagnosis has traditionally been viral isolation in tissue culture, the polymerase chain reaction has been demonstrated to be more sensitive than culture, highly specific, and rapid. Immunoglobulin has been used as a therapeutic agent for neonates with enterovirus disease; however, clinical efficacy has not been proven. Specific antiviral therapy for enteroviruses is in development. Pleconaril is an investigational agent that inhibits viral attachment to host cell receptors and uncoating of viral nucleic acid. It has broad and potent anti-enterovirus activity, excellent oral bioavailability, and is well tolerated. Some clinical trials have demonstrated benefit in children and adults with enterovirus meningitis, and in adults with upper respiratory tract infections caused by picornaviruses (rhinoviruses or enteroviruses). Data summarizing compassionate use for severe enterovirus diseases (including neonatal sepsis) also suggest possible benefit. Limited pharmacokinetic data are available in infants and neonates. A multicenter, placebo-controlled, randomized trial of pleconaril in neonates with severe hepatitis, coagulopathy, and/or myocarditis is currently being conducted.

A 7-year-old castrated male German Shepherd Dog was evaluated for lethargy, icterus, and sepsis. Porcupine quills had been removed from the dog's face 1 month prior to examination; progressive right forelimb lameness had developed soon after removal of the quills. Septic arthritis of the right elbow joint was diagnosed and was unresponsive to antimicrobial and anti-inflammatory treatments. At the time of referral, the dog had developed endocarditis, septicemia, and disseminated intravascular coagulation. Via ultrasonography, a foreign body consistent with a porcupine quill was detected in the medial portion of the right humeroradial joint. The dog did not respond to initial supportive treatment and died as a result of cardiac arrest. Postmortem examination confirmed the presence of a quill in the medial compartment of the right elbow joint and severe acute endocarditis with septic emboli to the kidneys and spleen. Ultrasonographic examination should be considered as a diagnostic tool when septic arthritis secondary to a foreign body is suspected in dogs.

In this retrospective study, we describe 14 cats diagnosed with hepatic abscesses. The objective of the study was to report the clinical signs, physical examination findings, clinicopathologic findings, and outcomes in affected cats. These findings were then compared with those previously reported in dogs and humans. Clinical signs were vague and included anorexia, lethargy, and weight loss. Only 23% of cats had fever, whereas 31% were hypothermic. Increases in serum activities of alanine aminotransferase and alkaline phosphatase were found in 45 and 18%, respectively, of the 11 cats that had laboratory work performed. Abdominal ultrasound examinations were performed in 7 cats, and abnormalities were found in 71% of them. Four cats had solitary abscesses, all of which were located in the right liver lobes. The other 10 cats had multifocal small abscesses or microabscesses, and all of these cats had clinical signs suggestive of sepsis. Cytologic evaluation of samples obtained by abdominocentesis indicated septic inflammation in 67% of cats in which peritoneal fluid was analyzed. Hepatic abscess cultures yielded polymicrobial growth in 66% of the cats: Escherichia coli was the most commonly cultured organism. Overall mortality rate was 79%. All survivors underwent exploratory laparotomy for partial hepatectomy to resect the abscess followed by medical management. Hepatic abscesses should be considered in cats with signs consistent with sepsis. More routine use of ultrasonography may aid in earlier diagnosis of hepatic abscesses, potentially improving prognosis and outcome.

A nontuberculous Mycobacterium ulcerans-like organism was identified as the causative agent of an epizootic of mycobacteriosis in a colony of African tropical clawed frogs, Xenopus (Silurana) tropicalis, at the University of California, Berkeley. Diverse clinical signs of disease were observed, including lethargy, excess buoyancy, coelomic effusion, cutaneous ulcers, and granulomas. Visceral granulomas, ulcerative and granulomatous dermatitis, coelomitis, and septicemia were common findings at necropsy. Identification of M. ulcerans-like organisms was based on molecular and phenotypical characteristics. The findings of this investigation indicate that this M. ulcerans-like organism is a primary cause of morbidity and mortality in aquatic anurans and should be considered in the differential diagnosis of coelomic effusion in amphibians. Furthermore, if this Mycobacterium species ultimately is identified as M. ulcerans, X. tropicalis should be considered a potential source of this important public health pathogen.
