A case of West Nile virus (WNV) infection in a captive 4-month-old Arctic wolf (Canis lupus) is described. The animal had vomiting, anorexia, and ataxia before death. Histopathology revealed multifocal severe renal lymphoplasmacytic vasculitis, mostly affecting small arterioles, with fibrinoid degeneration of some vessel walls. Many small foci of gliosis were detected in the cerebral cortex. West Nile virus was demonstrated in the kidneys and cerebrum by immunohistochemistry and polymerase chain reaction. The described renal changes represent a novel pathological finding of WNV infection.

A 4-year-old male Boxer dog with a history of vomiting, diarrhea, and weight loss moved from West Africa to Lyon, France, where it was further evaluated. Radiographs revealed pleural effusion and enlargement of tracheobronchial lymph nodes and liver. Cytologic examination of the pleural effusion and a fine needle aspirate specimen of the liver showed mixed mononuclear inflammation with nonstaining rod structures within epithelioid histiocytes. At necropsy, the main gross pathologic findings were exudative pleuritis, nodular hepatitis, and infarcts and caseous nodules in the kidneys. The main histologic lesions were granulomatous hepatitis, granulomatous pneumonia, fibrinous leukocytic pleuritis, necrotic and fibro-calcified granulomatous lymphadenitis, and granulomatous nephritis. A Ziehl-Neelsen stain applied to both cytologic and histologic samples was positive for acid-fast bacilli. Bacterial culture of the pleural fluid was positive for Mycobacterium tuberculosis. Cytology is a valuable tool in the diagnosis of this important zoonotic disease.

Lassa fever is an acute viral illness caused by Lassa virus, which is hosted by rodents in the Mastomys natalensis species complex and rarely imported to countries outside of those areas in Africa where the disease is endemic. Lassa fever is characterized by fever, muscle aches, sore throat, nausea, vomiting, and chest and abdominal pain. Approximately 15%-20% of patients hospitalized for Lassa fever die from the illness; however, approximately 80% of human infections with Lassa virus are mild or asymptomatic, and 1% of infections overall result in death. On August 28, 2004, a man aged 38 years residing in New Jersey died from Lassa fever after returning from travel to West Africa. This report summarizes the clinical and epidemiologic investigations conducted by federal, state, and local public health agencies. The findings illustrate the need for clinicians and public health officials to remain alert to emerging infectious diseases and to institute appropriate measures to promptly identify and limit spread of unusual pathogens.

The objective of this study was to outline the epidemiology of Ciguatera fish poisoning as seen in a general practice serving two industrial seaports in Trinidad and Tobago, in order to highlight the potential public health implications. A retrospective study was undertaken of all the cases of Ciguatera fish poisoning identified between November 1, 1992 and October 31, 1998 in a seaport general practice to identify signs, symptoms and treatment. An investigation of one outbreak was undertaken. Four outbreaks affecting 42 male ship crewmembers were identified. The suspect fish were caught in northern Caribbean waters en route to Trinidad and Tobago. The most common early symptoms were diarrhoea, vomiting, abdominal cramps, pruritus and tiredness. In the third outbreak, dysaesthesia was common. Progression to muscular weakness, ataxic gait, unsteadiness and other neurotoxic signs were seen in moderate to severe disease. Hypotension was an important prognostic sign in the initial case. Treatment was symptomatic and supportive and included vitamins B12 and BCO, folic acid, prostigmine, steroids and antihistamines as indicated. In the investigation of the second outbreak, the relative risk of 'eating fish meat' was 5 (95% CI 1.45, 17.27, p < 0.0001). Abdominal symptoms, pruritus, and muscle weakness with a history of consuming a fish-meal were diagnostic indicators of 'ciguatera fish poisoning.' All cases were industrial ship crewmembers. It is suggested that increased clinician awareness with early and appropriate treatment, and focussed public health intervention may help limit the potential public health impact of ciguatera poisoning in industrial ship crewmembers and other fish-consuming communities in the future.

In December 2004, an infant aged 29 days in West Virginia died from pertussis after exposure to adult family members with probable undiagnosed pertussis. Pertussis (i.e., whooping cough) is a prolonged respiratory illness caused by the bacterium Bordetella pertussis and characterized by a violent cough, inspiratory whoop, and posttussive vomiting. The cough often lasts from several weeks to up to 3 months. However, adolescents and adults, even those previously vaccinated as children, often have disease not recognized as pertussis, leading to intrafamilial and nosocomial transmission. In the United States, children aged <6 months are at the highest risk for severe illness or death from pertussis because most infants do not complete their primary vaccination series until age 6 months. This report summarizes results of the West Virginia Department of Health and Human Resources (WVDHHR) case investigation, which underscore the critical need to prevent pertussis transmission to infants from adolescents and adults with undiagnosed disease.

A three-year observational study of patients undergoing tonsillectomy at the University Hospital of the West Indies was conducted to determine the incidence of postoperative vomiting. Data were collected to assess possible risk factors for vomiting as well as possible alleviating agents. Two hundred and fifty-two patients were included in the study and a thirteen per cent incidence of postoperative vomiting was found. This is significantly less than that quoted in other studies (40-73%). Results also showed that steroids significantly reduced the incidence of postoperative vomiting in the study population. Muscle relaxants reversal agents and antibiotics particularly co-trimoxazole and ceftriaxone significantly increased its incidence. Usual antiemetic agents including dimenhydrinate (gravol) and promethazine (phenergan), as well as drugs known to possess antiemetic properties such as midazolam and propofol, lacked any significant protective effect against emesis. Opioid analgesia, inhalational induction and blood loss of greater than 10% of estimated blood volume appeared to increase emesis but failed to achieve statistical significance.

We describe a case of a previously healthy 2-year-old female patient with rash, fever and vomiting for 10 days who presented for medical attention with acute profound balance and gait disturbances and intentional movement dysmetria. West Nile virus-specific IgM and IgG antibodies were detected in the patient's cerebrospinal fluid.

Lithium (Eskalith) is commonly used in the treatment of depressive and bipolar affective disorders, in a population at relatively high risk for overdose. Lithium may help correct a chemical imbalance in the brain; however, it has a comparatively narrow therapeutic index. Thus, lithium intoxication is a frequent complication of chronic lithium therapy. The central nervous system (CNS) is the major organ system affected, although the renal, gastrointestinal (GI), endocrine, and cardiovascular (CV) systems also may be involved. Here we present a forty-two-year-old Caucasian female with altered mental status, inability to eat, speak or walk properly, with shaking and vomiting for three days. Past medical history was significant for hepatitis C and bipolar disorder. Vital signs were within normal limits. Physical exam revealed a patient with aphasia, tremor, and an expressionless face, able to make eye contact and move all four extremities. However, she was unable to follow commands and she expressed rigidity of extremities, mild tachycardia, and stupor. Severely elevated serum lithium levels were found. A diagnosis of severe lithium toxicity was made and the patient was admitted to the telemetry unit. Intravenous hydration with normal saline was initiated as the patient had normal kidney function, and urinary output was monitored. All psychotropic medications were held except for a benzodiazepine. In the meantime the patient developed acute respiratory distress, was intubated on clinical grounds and was transferred to the intensive care unit. Acute cardiogenic pulmonary edema and other causes of respiratory distress were ruled out; diagnosis of Adult Respiratory Distress Syndrome (ARDS) was made. After two months of mechanical ventilation, the patient was stabilized. Mental status, vital signs, and all laboratory parameters including thyroid function tests, normalized. The patient was transferred to a rehabilitation center. This is a rare case of ARDS associated with lithium intoxication.

We evaluated prescription and correct dosing of a 14-day course of dispersible zinc tablets prescribed to young children with diarrhea by community and facility workers in rural, southern Mali, West Africa. One hundred twenty-three children were followed at home on days 3 and 14 after being prescribed zinc. The age-appropriate dose of zinc was dispensed in 94% of cases. Ninety-five percent of mothers dissolved the tablet in a small amount of water and gave it with a spoon. Only eight caretakers reported problems with zinc administration: either vomiting or refusal to take the tablets. Sixty-four percent of children received the full 14-day course of treatment, and more than 89% of children were given at least a 10-day course of zinc treatment. The levels of correct administration were very good but might be lower under non-research conditions.

National prevalence of Giardia infection in dogs and cats presenting to clinics with vomiting and/or diarrhea was examined using the IDEXX SNAP Giardia test kit. Veterinary practices across the United States were sent an invitation to participate in the survey and asked to use the test on fecal samples from the target population. The survey requested that the clinics report the results of 20 or more tests. A total of 21,092 results were reported, comprised of 16,114 dogs and 4,978 cats. Analysis of the data (excluding the handful of results reported from Puerto Rico) showed a Giardia prevalence of 15.6% among dogs tested, and 10.8% among cats. This difference was statistically significant (p < 0.001). Regional categorization into Northeast, Southeast, West, and Midwest drew out significant (p < 0.001) differences in prevalence in most cases for dogs; the differences were not significant for cats. These differences and other variables are currently being examined with this and additional data sets. We conclude on the basis of the SNAP test diagnostic that Giardia is a common enteric agent among dogs and cats with gastrointestinal signs.
