In the United States, human monocytic ehrlichiosis (HME) and human granulocytic ehrlichiosis (HGE) represent two clinically indistinguishable yet epidemiologically and etiologically distinct diseases caused by Ehrlichia chaffeensis and a bacterium similar or identical to E. equi, respectively. Infection with these emerging tickborne pathogens results in acute, influenza-like illnesses with fever, headache, malaise, and frequently leukopenia and/or thrombocytopenia. Connecticut and New York have initiated statewide laboratory-based surveillance to determine the magnitude and geographic extent of ehrlichiosis. This report summarizes results from the first 3 years of surveillance, which showed that rates of ehrlichiosis were similar in counties in both states where the disease occurs, and highest age-specific rates occurred among persons aged >40 years.

Salmonella typhimurium phage type (PT) or definitive type (DT) 104 is a virulent pathogen for humans and animals, particularly cattle. It has been isolated increasingly from humans and animals in the United Kingdom and several other European countries and, more recently, in the United States and Canada. Humans may acquire the infection from foods of animal origin contaminated with the infective organism. Farm families are particularly at risk of acquiring the infection by contact with infected animals or by drinking unpasteurized milk. The symptoms in cattle are watery to bloody diarrhea, a drop in milk production, pyrexia, anorexia, dehydration and depression. Infection may result in septicemic salmonellosis and, upon necropsy, a fibrinonecrotic enterocolitis may be observed. The infection occurs more commonly in the calving season than at other times. Feedlot cattle and pigs may also be affected. Prolonged carriage and shedding of the pathogen may occur. Symptoms in humans consist of diarrhea, fever, headache, nausea, abdominal pain, vomiting, and, less frequently, blood in the stool. Salmonella typhimurium DT104 strains are commonly resistant to ampicillin, chloramphenicol, streptomycin, sulfonamides, and tetracycline.

Isolated involvement of the sphenoid sinus is a relatively uncommon entity. We present a review of the most important series. Acute and chronic diseases are separated. Acute sphenoid sinusitis is a potentially catastrophic infectious disease. It is frequently initially misdiagnosed, and, due to the severe intracranial complications, a genuine medical and surgical treatment is recommended. Chronic sphenoid lesions may pose a problem of etiologic diagnosis. It may be difficult to differentiate between benign and malignant lesions. The most common presenting symptom is headache, followed by visual symptoms and cranial nerves palsies. Radiographically, computed tomography is the gold standard. Treatment includes antibiotic therapy and surgical drainage. This drainage is now done through an endoscopic approach.

Migrant farmworkers lead a hard life filled with strenuous work, stress, and anxiety about employment; live under substandard conditions; and rarely get the health care they require. Preventive care is a luxury they cannot afford. Year-round nutritious meals are rarely possible, due to long working hours, traveling, and living in housing without adequate cooking and refrigeration facilities. Children may attend up to six or more schools during the course of a school year. Crowded housing conditions support the invasion of parasites, infectious diseases, and viral infections. Dermatological conditions from working around a wide variety of plants, dirt, and in the sun are frequent. Exposure to pesticides, herbicides, and other chemical additives creates the likelihood of acute reactions, such as headaches and rashes, and also puts workers at risk of developing chronic diseases as the level of exposure rises because of accumulation and mix of various chemicals. Yet, we know little about the health status of this population. We are unable to estimate crude death rates, age-specific death rates, or prevalence rates of most common causes of death, such as heart disease,cancer and stroke. There is no information about occupational accident rates, infectious disease rates, or even postneonatal mortality. We do know that when migrants go to a clinic, they are often likely to have the chronic conditions of hypertension or diabetes. They present symptoms of acute conditions such as dental problems, dermatitis, otitis media among children, and acute upper respiratory infections. Women frequently need obstetrical care, reflected (ABSTRACT TRUNCATED AT 250 WORDS)

Tularemia is an arthropod-borne infectious disease caused by Francisella tularensis, a gram-negative microorganism that normally resides in a wide range of wild and domestic animals. The disease is characterized by a sudden onset with high fever, headache, malaise, chills, myalgia, and arthralgia. A short time after exposure, an inflamed and ulcerated lesion rapidly appears at the site of entry. A regional lymphadenopathy follows the cutaneous presentation. Cultures from the lesions or blood generally give negative results. Histopathologic examination reveals either a nonspecific inflammatory infiltrate or an infectious granuloma. The most useful laboratory procedure in the diagnosis of tularemia is serologic tests. Streptomycin, gentamicin, and tetracycline are the drugs of choice in the treatment. Quinolones are also effective. Tularemia is fairly rare in Turkey. We present a typical case of ulceroglandular tularemia transmitted from a sheep to a young man.

Bone marrow suppression is an important adverse reaction to most betalactam antibiotics. Recently it was suggested that piperacillin/tazobactam (PT) also may cause bone marrow toxicity. We retrospectively analyzed 100 i.v. antibiotic treatment courses (mean duration 12.5 days) in 38 patients (median age 14 years) with cystic fibrosis (CF) who were treated in our hospital. Of the patients receiving PT (84%), 6 patients (18.75% of PT-treated patients, 10.3% of PT treatment courses) developed fever, malaise and headache during treatment without signs of acute infection. In one patient definite thrombocytopenia and neutropenia, in two others a milder decrease in leukocyte and thrombocyte counts was observed after the onset of fever. The events were time- and dose-dependent occurring between day 11 and 15 of treatment. Treatment courses lasted longer (14.2 vs 11.3 days; p < 0.05) and patients had received a higher cumulative dose of PT (4919 +/- 1975 mg/kg b.w. vs 3161 +/- 1635 mg/kg; p < 0.02, Student's t-test) in the affected group than in the unaffected group. After discontinuation of PT, fever subsided within 24 h and blood cell counts normalized. We hypothesize that these fever episodes and changes of blood parameters are related to PT therapy.

Bacillary angiomatosis (BA) is an infectious disease characterized by proliferative vascular lesions; it mainly affects HIV-positive patients. Multiple cutaneous nodular lesions together with fever, chills, malaise, anorexia, vomiting and headache are the most important clinical manifestations. It may also involve the heart, liver, spleen, bones, lung, muscles, lymph nodes, central nervous system and other organs. Erythromycin, 500 mg four times a day, is the drug of choice. The importance of this lesion lies in its clinical and histological similarity with other diseases. Cutaneous and oral lesions of BA clinically resemble Kaposi's sarcoma (KS). Histopathologically, BA may be confused with angiosarcoma, pyogenic granuloma and epithelioid hemangioma. We report two HIV-positive men with BA lesions in the oral mucosa. Diagnosis was confirmed by biopsy and Warthin-Starry silver staining.

The aim of this prospective study was to compare epidemiological data and clinical features in children and adults with tick-borne encephalitis (TBE). Patients with aseptic meningitis diagnosed at the University Medical Centre, Department of Infectious Diseases, Ljubljana, Slovenia, from June to August 1997, in whom the diagnosis of TBE was ascertained by the presence of serum IgM antibodies against TBE virus, who were serologically negative for Borrelia burgdorferi sensu lato and had a negative PCR CSF result on enteroviral infection, were included in the study. Out of 213 patients with aseptic meningitis, 80 (37.56%) fulfilled inclusion criteria. There were 20 children and 60 adults. In both groups males predominated. Virtually all patients had headache and fever, and more than 50% suffered from vomiting. The majority of patients in both groups recalled a tick bite, had a biphasic course of the illness, and was found to have obviously expressed meningeal signs. In both groups the median CSF leukocyte count was somewhat lower than 100 x 10(6)/l with a predominance of lymphocytes. Children were more often given antibiotics during the initial phase of TBE than adults (p = 0.0095). Several other statistically significant distinctions (p < 0.05) were found including the frequency of fatigue, malaise, vertigo, photophobia, myalgias, arthralgias, as well as elevated CSF albumin and protein concentration, elevated albumin quotient and IgG quotient; all these findings were more often present in adults. In addition a longer duration of fever, more frequent need for anti-edematous treatment and longer hospitalization were found in adults. Direct comparison of clinical and epidemiological characteristics of TBE in children and adults revealed differences in several clinical and laboratory features and corroborates the previous conclusion that TBE in childhood is a milder illness than TBE in adults.

On September 28, 1999, a previously healthy 48-year-old man from California sought care at a local emergency department (ED) and was hospitalized with a 2-day history of fever (102 F [38.9 C]), chills, headache, photophobia, diffuse myalgias, joint pains, nausea, vomiting, constipation, upper abdominal discomfort, and general weakness. On September 26, he had returned from a 10-day trip to Venezuela. On September 29, an infectious disease physician from the ED contacted the Marin County Health Department (MCHD) about the patient's symptoms; MCHD reported his illness to the California Department of Health Services (CDHS) as a suspected case of viral hemorrhagic fever. This report describes the investigation of the case.

The Erve virus is suspected to cause severe headache in humans, lasting several days (thunderclap headache). Mice are characterized as a probable reservoir for the Erve virus. We tested 396 wild mice for Erve virus using an immunofluorescence test and found Erve virus antibodies in five cases, showing that small mammals form a reservoir for Erve virus. If ticks are the vector for the virus, a coincidence with borreliosis should exist. We were unable to confirm this in a homogeneous cohort of 955 young men, 62 of whom tested positive for borreliosis. This group did not test positive significantly more often in the immunofluorescence test than a gender- and age-matched control group.
