More than half of the cases of plague in the United States are diagnosed in children. In the 1970s, 105 cases were reported, a 350% increase over the 1960s. Plague should be considered in the differential diagnosis of children from the western United States who have sepsis, especially those with lymphadenopathy. Complications of plague include meningitis, metabolic encephalopathy, abscess, and pneumonia. With appropriate treatment, prompt clinical response usually occurs. Careful isolation and epidemiologic investigation are essential to prevent the spread of the disease.

Your recent lead article on toxic shock and tampons (November 1, p. 1161) prompts me to report a case of pelvic infection and staphylococcal septicemia 8 days after the insertion of a Lippes loop. Pelvic infection is a recognized complication of IUDs; although there have been 2 reports of endocarditis occurring in susceptible patients following the insertion of an IUD, septicemia is rare. A previously healthy 31-year old married woman had a loop inserted at a family planning clinic. 3 days later she developed sweating, vomiting, confusion, and cough and during the following 48 hours became disoriented with hallucinations. She was referred to the hospital with suspected encephalitis and on admission was febrile (38.8 degrees Celsius) and stuporose but responded to simple commands. Blood pressure was 95/60 mmHg but there were no other abnormal signs. Hemoglobin was 12.2 g/dl, white blood count 4.0x109/1 (80% neutrophils), erythrocyte sedimentation rate 70mm in the 1st hour; cerebrospinal fluid normal. Chest x-ray examination revealed patchy consolidation in the upper lobes of both lungs and an electroencephalogram showed bilateral nonspecific abnormality. 3 blood cultures taken on admission yielded penicillin-resistant Staphylococcus aureus. She was treated with high-dose intravenous cloxacillin and 24 hours after starting the antibiotic had improved markedly and the IUD was removed. Culture from the coil and also from a high vaginal swab yielded Staph aureus with a similar antibiogram to that of the organism cultured from the blood. Subsequent recovery was uneventful, although repeat chest x-ray examination showed small abscess cavities in the upper lobes of both lungs. The patient was discharged 4 weeks after admission and serial chest radiographs have confirmed complete resolution of the pneumonia and abscesses. There is little doubt that this patients' septicemia with lung abscess formation and encephalopathy originated in the genital tract. The patient was both toxic and shocked but was different from patients with the recently described toxic shock syndrome in that her blood culture was positive for Staph aureus. The case provides another example of the importance of this organism as a cause of infection associated with the insertion of foreign bodies into or through the vagina.

The clinical course is described of a 28-year-old woman who was severely ill following ingestion of a Do-Do tablet (which consists of ephedrine, caffeine and theophylline), 24 h after discontinuing phenelzine treatment. Signs and symptoms were delayed for 8 h after which she developed encephalopathy, neuromuscular irritability, hypotension, sinus tachycardia, rhabdomyolysis and hyperthermia. Her illness was complicated by pneumonia and adult respiratory distress syndrome (ARDS). The management of monoamine oxidase inhibitor (MAOI) toxicity, which can arise from interactions and overdoses, is discussed. It should be remembered that, despite the increase in use of alternative and safer antidepressants, MAOI interactions still occur and unless they are managed appropriately, are potentially fatal. Patients need to be warned that restrictions apply for up to 2 weeks after stopping the medication, and doctors need to be aware that serious interactions can occur in this time period.

Pertussis, one of the most communicable respiratory diseases, has a wide spectrum of severity, which generally decreases with age. Adults with waning immunity, who have subclinical pertussis, frequently infect nonimmunized or underimmunized children within the same household. High levels of pertussis activity persist, even in highly immunized populations. Infants less than 2 months of age have the highest attack rate and greatest morbidity and mortality. Serious complications include apnea, pneumonia, encephalopathy, and recurrence of coughing spasms with cyanosis. These complications further contribute to a protracted disease course in young infants. Although a decrease in the incidence of pertussis has occurred since the advent of active immunization in the United States, recent data show a striking resurgence in cases. Widespread transmission of disease, even in immunized individuals, and subclinical adult infection, which serves as a reservoir for disease in young infants, underscore the need for a more effective vaccine immunization strategy.

Cytomegalovirus encephalitis (CMVE) is frequently diagnosed only at postmortem because its specific clinical features have not been fully identified. We have described the clinical, radiologic, and laboratory features of CMVE in a retrospective review of 14 autopsy-confirmed cases of CMVE and compared them with a control group of demented acquired immunodeficiency syndrome (AIDS) patients without CMVE. CMVE was more common among homosexual men, and a subacute onset was more typical (mean duration of presenting symptoms was 3.5 weeks versus 18 weeks in demented controls). Median survival times were 4.6 weeks for CMVE and 28 weeks for controls. CMVE was accompanied by prominent systemic CMV infection at autopsy, including CMV adrenalitis (92%), CMV pneumonitis (42%), systemic Mycobacterium avium intracellulare (MAI; 58%), and CMV retinitis (58%). Hyponatremia and MAI bacteremia were found in 58% of CMVE cases. Polymerase chain reaction (PCR) of CSF samples identified CMV genome in 33% of CMVE cases. CMVE was associated with periventricular enhancement on CTs and periventricular lesions with meningeal enhancement on MRI scans. CMVE should be particularly suspected in homosexual men presenting with subacute encephalopathy who have had AIDS for more than 1 year and have a history of systemic CMV infection. Other features supporting the diagnosis of CMVE include periventricular lesions, hyponatremia, and identification of CMV genome in CSF by PCR.

We report two cases of AIDS whom we have recently experienced. One patient was a 54-year-old man who admitted our hospital due to third degree burn. In this case, we did not know whether or not he was suffered from AIDS, when he was delivered by the ambulance. In autopsy, pneumocystis carinii pneumonia and renal tuberculosis were found in addition to marked decrease of T cells in lymph nodes. The other patient was a 40-year-old man with remarkable symptoms of central nervous system. Route of infection of HIV is unknown. He had dementia, left hemiplegia, bulbar palsy, progressed to rigid decorticate posture and died of respiratory arrest due to involvement of the brain stem, despite of treatment including use of 3'-azido-2',3'-dideoxythymidine (AZT). Magnetic resonance (MR) images showed progressive cerebral atrophy and a diffuse high signal intensity area of cerebral white matter on T2-weighted MR images, suggesting the diagnosis of HIV-induced encephalopathy.

Twelve consecutive patients admitted for bleeding from ruptured gastric varices were treated with transjugular intrahepatic portosystemic shunts and followed for a mean of 6 +/- 3 months (range: 8-293 days). The shunt was performed successfully in all 12 patients. The shunt occluded in 3 patients (respectively 19, 101 and 103 days after insertion) of whom one remained asymptomatic and two experienced rebleeding. Four patients presented with acute encephalopathy, spontaneously in two and after rebleeding in two. Three patients died, two after rebleeding and one of septic shock secondary to pneumonia. Overall, 9 patients survived a mean of 211 +/- 92 days with no rebleeding, 8 of whom have not yet experienced any complications. These results suggest that transjugular intrahepatic portosystemic shunts could be useful in treating hemorrhages from ruptured gastric varices and in preventing their recurrence.

We experienced a 39-year-old male who developed neurological complication during a course of Mycoplasma pneumoniae pneumonia. The diagnosis of M. pneumoniae pneumonia was made on the basis of elevation of specific antibody (CF) titer in convalescent serum. Electroencephalogram showed diffuse damage in the brain, but no other abnormalities were not found on brain CT-scan and MRI. In the cerebrospinal fluid, the number of cells did not increase and the M. pneumoniae CF titer was not elevated. From these results, we concluded that encephalopathy in this patient was raised by an allergic reaction of the brain tissue to M. pneumoniae antigen. Until now, encephalitis or meningoencephalitis accompanied with M. pneumoniae infection has been reported by many investigators, but reports on encephalopathy due to M. pneumoniae are few. Therefore, we reported herein a case of encephalopathy following Mycoplasma pneumoniae pneumonia with several references.

Seven patients with decompensated posthepatitis B cirrhosis were treated with low doses of interferon alpha. The initial plasma level of HBV-DNA ranged from 3.0 to 189.3 pg/ml, and that of ALT from 37 to 156 IU/l. Liver biopsies demonstrated ongoing piecemeal necrosis. In sera of all but one patient, HBV-DNA became undetectable by hybridisation techniques within 10 to 28 weeks. Plasma HBeAg became negative in four and HBe-antibodies positive in three patients. Serum transaminase levels showed a marked initial rise 3 to 13 weeks after onset of therapy; they dropped to normal values later in all except one patient. Therapy was initiated at 1 MU (million units) three times a week for 2 weeks and was increased to 2.5 MU for 16 weeks. Later, this dosage was raised to 5 MU three times a week in some patients. Complications included variceal haemorrhage, aggravation of ascites or of encephalopathy, development of pneumonia, recurrence of spontaneous bacterial peritonitis or of gastric ulcer bleeding. One year after stopping the therapy, three patients are well and without any feature of liver decompensation. Three patients died before they could undergo a liver transplantation. In one patient treatment was interrupted because of marked exacerbation of liver cell necrosis. It thus seems possible to suppress HBeAg and HBV-DNA in patients with decompensated cirrhosis. This is important to prepare them for possible liver transplantation. Interferon should be initiated at low doses and the patients be very carefully monitored. Prophylactic therapy for bacterial peritonitis and for variceal haemorrhage is warranted.

We present a case of acute lethal poisoning by oil of "epazote" (oil of chenopodium), in a 2 y 9 m female. The volatile oil was administered according to the advice of a "curandera" (female healer), in a total quantity of 40 ml. Clinical features of the poisoning were: vomiting, deep coma, seizures, mydriasis, apnea, metabolic acidosis, neurogenic shock and death. The EEG suggested a diffuse encephalopathy, the CT scan with an image of severe brain edema and ventricular collapse. Relevant postmortem findings were brain edema and neuronal necrosis, pneumonia, enteritis, pericholangitis, mild pancreatitis and tubular necrosis. The phytochemical analysis of volatile oil identified ascaridol, the main active compound of the chenopodium herbs, in a quantity of 39 mg/ml (1,560 mg in the dose administered), and Chenopodium graveolens as the plant employed to prepare it. According to the age of the patient, 60 mg of ascaridol would be the recommended dose formerly used in the treatment of parasitic disease. Thus 1,560 mg was 26 times higher than the recommended dose, and exceeded by 56% the dose of 1,000 mg reported as lethal in humans.
