The timeliness of reporting four nationally notifiable diseases was examined using data reported via the National Electronic Telecommunications System for Surveillance. Timeliness of reporting varied by disease (bacterial meningitis: median 20 days; salmonellosis: median 22 days; shigellosis: median 23 days; and hepatitis A: median 33 days) and by state. These findings indicate a need to standardize surveillance definitions and to account for reporting differences between states in interpreting regional disease trends or detecting multistate disease outbreaks.

Overwhelming infections caused by encapsulated bacteria, salmonella spp. and Plasmodium falciparum (in malarious areas) are an important cause of morbidity and death in patients with sickle cell disease. Bacterial infections afflicting these patients include fulminant meningitis and septicaemia caused by Str. pneumoniae and H. influenzae type b, and non-typhoid salmonellosis. Children less than five years of age are at greatest risk for meningitis and septicaemia, while salmonella osteomyelitis is probably common to all age groups. The most important contributing factors to this increased susceptibility to encapsulated bacteria are: a state of functional asplenia, an opsonophagocytic defect due to an abnormality of the alternative complement pathway, and a deficiency of specific circulating antibodies. Devitalisation of gut and bone due to repetitive vaso-occlusive crises, saturation of the macrophage system with red cell breakdown products of chronic haemolysis, and underlying splenic and hepatic dysfunction all predispose to salmonella infections. Seventy per cent of septicaemias and meningitis among under-fives with sickle cell disease is caused by Str. pneumoniae. Septicaemia frequently presents with sudden fever, few prodromal features, and a deceptive appearance of well-being, followed within hours by rapid relentless progression to shock and death. Adrenal haemorrhage is common, and mortality can be as high as 50 per cent, unless intravenous antibiotic, with or without steroid therapy, is promptly initiated. The clinical presentation of bacterial meningitis, its management and mortality follow the normal patterns, but recurrent meningitis and cerebrovascular morbidity are common in patients with sickle cell disease. An acute pulmonary involvement, indistinguishable from bacterial pneumonia (the 'chest syndrome') is the commonest single complication of sickle cell disease at any age. Str. pneumoniae is responsible for about half of the episodes. The protective values of the pneumococcal vaccine and long-term penicillin prophylaxis remain to be established in sickle cell disease. Over 70 per cent of haematogenous osteomyelitis in sickle cell disease is caused by salmonellae. The distinction from vaso-occlusive bone crisis is often difficult, but the presence of multiple, often symmetrical bone involvement, diaphyseal fissuring and involucrum should suggest osteomyelitis rather than bone infarction. Chloramphenicol remains the drug of choice and often has to be given in high doses for up to six weeks. The role of surgery is limited by the presence of multiple bone involvement and the known anaesthetic risks in this group.(ABSTRACT TRUNCATED AT 400 WORDS)

Results obtained by standard tube agglutination (STA) test which is the most widely used serological method for brucellosis, are often evaluated together with the clinical and microbiological findings, and the titers of > or = 1/160 are generally accepted as an indicator of acute infection. However, cross reactions with some other bacteria may lead to false positive results in this test. In this study, the performance of STA test in the diagnosis of brucellosis has been evaluated by using serum samples obtained from 40 culture positive brucellosis patients, 54 patients with bacterial infections other than brucellosis and 40 healthy blood donors. The distribution of infections and number of patients were as follows; urinary infection (n: 16), salmonellosis (n: 15), bacterial meningitis (n: 5), tuberculosis (n: 4), pneumoniae (n: 3), osteomyelitis (n: 3), infective endocarditis (n: 2), peritonitis (n: 2), diabetic foot infection (n: 2), acute cholecystitis (n: 1), and catheter infection (n: 1). STA were positive in all of the brucellosis patients between the titers of 1/160-1/1280 (mean: 1/640), whereas STA were found negative in all of the healthy subjects. Nevertheless two patients whose stool cultures yielded Salmonella spp., one patient whose urine culture yielded E. coli, one patient whose diabetic foot lesion culture yielded group A beta-hemolytic streptococci, exhibited STA positivity at the titers of 1/160. There was no history of brucellosis or presence of co-infections in the patients with non-brucellosis infections and blood donors. In conclusion, cross reactions due to the presence of other bacterial infections should be considered for the evaluation of Brucella STA test results, together with the endemicity of the country of interest and seropositivity rate of the population.

For the laboratory evaluation of the severity of intoxication syndrome, the spectral characteristics of low and median molecular weight substances (LMMWS) were studied in the plasma and red blood cells of 129 children with bacterial infections, among whom there were 76 children with acute intestinal infections (Flexner's dysentery, Sonne dysentery, and salmonellosis) and 53 children with bacterial purulent meningitis of hemophilic and meningococcal etiology. In the acute period, all the examinees were found to have considerable qualitative and quantitative distinctions of blood spectrograms from the normal values. There was an association of the spectral characteristics of blood LMMWS with the nosological entity, etiology and stage of disease, and the severity of intoxication syndrome. The maximum distinctions from the normal values were detected in children with bacterial meningitis running with complicating the course of acute intestinal infection. There was an increase in the blood levels of LMMWS with the concomitant intercurrent diseases occurring, as compared with the smooth uncomplicated course of disease. The studies of the natural history of disease have indicated a gradual normalization of blood spectrograms; however, in bacterial meningitis, insignificant deviations preserved at the stage of convalescence. The spectral characteristics of plasma and red blood cell LMMWS are proposed to use for the objective appraisal of the severity of intoxication syndrome and the reserve detoxification capacities of blood in children with bacterial infections.

Non-typhoidal salmonellae are important pathogens causing bacteraemia, especially in immunocompromised patients, but there are limited data explicitly describing the clinical characteristics and outcome in these individuals. Recurrent invasive salmonellosis has been recognised as an AIDS-defining condition in HIV-positive patients since the 1980s. Salmonella meningitis is an infrequent complication of Salmonella sepsis, accounting for 0.8-6% of all cases of bacterial meningitis, and is associated with a high mortality rate.

Non-typhoidal Salmonella usually manifests as a self-limited acute gastroenteritis but may also cause severe invasive infections almost exclusively among children or immunosuppressed patients. A previously healthy 22-year-old man developed high fever with coma, multiple organ failure and shock. He had visited another hospital complaining of fever 2 days previously and was diagnosed with a common cold. No obvious site of infection was identified by radiology and a rapid test for influenza A virus was positive, indicating possible influenza-associated encephalopathy. However, blood as well as CSF culture yielded Salmonella enterica serotype Enteritidis. Therefore, the patient was considered to be suffering from bacterial meningitis with septic shock concomitant with influenza infection. Antiviral drugs and therapy for septic shock were initiated. He stabilized relatively quickly and his mental status dramatically improved. The patient denied preceding gastrointestinal symptoms, but mentioned that he received positive fecal Salmonella species culture results without medical intervention about 3 months previously. His laboratory values showed marked improvement but his elevated inflammatory markers and fever were sustained. On the 17th day of hospitalization, he complained of back pain and MRI showed lumbar vertebral osteomyelitis. This case indicates that (i) invasive Salmonella infection can be developed even in previously healthy adults; (ii) chronic carriage of Salmonella is a predisposing factor to development of invasive infections, and influenza infection may contribute to such "breakthrough infections"; (iii) attention to manifestation of metastatic extra-intestinal foci even after resolution of sepsis is necessary.
