Leptospirosis is an infectious illness that usually develops 1 to 2 weeks after indirect or direct exposure to the urine of infected animals. Infection occurs through open cuts, absorption through intact mucous membranes, and drinking contaminated water. The typical presentation is a flulike syndrome of sudden onset that tends to resolve within 2 weeks. A mild immunologic phase usually presents as an aseptic meningitis. A more severe immunologic phase (Well's syndrome) can result in jaundice, renal failure, adult respiratory distress syndrome, disseminated intravascular coagulation, and death. Laboratory tests take too long to replace clinical diagnosis, which is imperative so that antibiotic therapy can begin before the fourth day of illness. Although leptospirosis is more common in tropical climates, detection in the continental United States is increasing. Early, accurate detection and treatment in the primary care setting are vital for limiting life-threatening complications.

A 50-year-old man with no medical history was admitted because of progressive respiratory distress, aseptic meningitis, disseminated intravascular coagulation, cholestatic hepatitis, and renal failure. Mycoplasma pneumoniae infection was confirmed serologically. The patient was treated with erythromycin and showed a favorable recovery. Although M. pneumoniae infection is usually a benign, self-limited acute respiratory disease, on rare occasions it can manifest itself with a fulminant course and multi-organ involvement, even in normal healthy individuals.

This study investigated the clinical manifestations and outcomes of central nervous system (CNS) infection by enteroviruses. Cases with CNS involvement among all enterovirus-culture-positive cases from January 1995 to June 2003 were retrospectively reviewed. Among 1028 enterovirus-culture-positive cases, there were 333 cases involving the CNS. Of these, the ratio of male to female subjects was 1.78, and the mean (+/- standard deviation) age was 6.83 +/- 5.9 years; 21 were premature neonates, and 10 failed to thrive. Disease entities included 282 cases of aseptic meningitis (84.7%), 44 cases of encephalitis (13.2%), and 7 cases of encephalomyelitis/polio-like syndrome (2.1%). Of these cases, 97.9% (326/333) had fever with peak body temperature at 38.9 degrees C, 85% had headache and vomiting, 70% had meningeal signs, 64% had neck stiffness, 16.6% (55/333) had change of consciousness, 5.4% (18/333) had seizures and 5.2% (17/333) had myoclonic jerks. Mannitol was administered in 77.2% of patients (257/333), along with intravenous immunoglobulin in 6.6% (22/333). Twelve cases received ventilator support. One patient died of hand-foot-and-mouth disease, encephalitis plus cardiopulmonary failure, and 2 premature neonates died of hepatic failure, disseminated intravascular coagulation, sepsis-like syndrome and myocarditis. Eighteen had neurologic sequelae, including 7 with limb weakness, 5 with epilepsy, 2 with sixth cranial nerve palsy, 3 with cerebral palsy, 4 with psychomotor retardation, 2 with spasticity, and 1 with hearing loss. Factors associated with unfavorable outcomes (death or sequelae) included younger age (p=0.0003), higher peak white blood cell count (WBC) [p=0.0009] and skin rash (p=0.005). Younger age and higher peak WBC were poor prognostic factors of severe enterovirus CNS infection. Death was related to neonatal enterovirus infection and enterovirus 71 infection in young children.

Japanese spotted fever (JSF), first reported in 1984, is a rickettsial disease characterized by high fever, rash, and eschar formation. A 61-year-old man was admitted to a local hospital in Nagasaki City, Japan, after several days of high fever and generalized skin erythema. His condition deteriorated and laboratory findings indicated disseminated intravascular coagulation (DIC). The patient was transferred to our hospital with mental disturbance and status epilepticus. Treatment included minocycline, and new quinolone. Definitive diagnosis was made with a serological test showing increased antibody levels against Rickettsia japonica. Rickettsial infections are rare, but should be seriously considered for the differential diagnosis of aseptic meningitis and encephalitis, as they show no response to conventional antibiotic treatment.

Dapsone (4,4'-diaminodiphenylsulfone, DDS), a potent anti-inflammatory agent, is widely used in the treatment of leprosy and several chronic inflammatory skin diseases. Dapsone therapy rarely results in development of dapsone hypersensitivity syndrome, which is characterized by fever, hepatitis, generalized exfoliative dermatitis, and lymphadenopathy. Here, we describe the case of an 11-year-old Korean boy who initially presented with high fever, a morbilliform skin rash, generalized lymphadenopathy, hepatosplenomegaly, and leukopenia after 6 weeks of dapsone intake. Subsequently, he exhibited cholecystitis, gingivitis, colitis, sepsis, aseptic meningitis, disseminated intravascular coagulation, syndrome of inappropriate antidiuretic hormone secretion, pneumonia, pleural effusions, peritonitis, bronchiectatic changes, exfoliative dermatitis, and acute renal failure. After 2 months of supportive therapy, and prednisolone and antibiotic administration, most of the systemic symptoms resolved, with the exception of exfoliative dermatitis and erythema, which ameliorated over the following 4 months. Agranulocytosis, atypical lymphocytosis, aseptic meningitis, and bronchiectatic changes along with prolonged systemic symptoms with exfoliative dermatitis were the most peculiar features of the present case.
