Complications such as bleeding and local infection are common, but severe infections like septicaemia, endocarditis and transmission of hepatitis may occur. We describe a 39 year old man with genital piercing who spent 43 days hospitalized because of Foumier's gangrene with necrotizing fascitis starting in the genital tract and perineum. He developed septicaemia and disseminated intravascular coagulation. A young woman with breast implants got severe mastitis after piercing her mamills. People with immunodeficiency, heart valve abnormality and present or future artificial prosthesis or skin disease should be discouraged from piercing. Since many disorders are not diagnosed when the piercing takes place, general restriction is recommended. Medical risks and consequences of piercing, especially of mucosal surfaces and cartilage, should not be underestimated.

Five patient cases from Växjö central hospital (uptake area 178 000 individuals) with Listeria meningitis, Pneumocystis jiroveci and tuberculosis pneumonia, Listeria sepsis, Legionella pneumonia and E coli sepsis are described. A doubled risk for infections has previously been observed for RA patients, as compared to healthy individuals. There is clearly an increased risk of tuberculosis (depending on the actual and historic environmental prevalence) for patients on TNF antagonists, and therefore tuberculosis screening is now mandatory before start of therapy. Since TNF has a central role in the immune defence, an increased risk of opportunistic infections like listeriosis. mycobacteriosis, and invasive fungal infections has been established. Eight hospitals in southern Sweden participate in a register for th...

It contains the capsid proteins VP1, 2, 3 and probably 4 and can be made RNA-free. It is based on the ISCOM technology ensuring non-toxic properties and good adjuvant effect. Vaccinated animals at doses above 16 ng were completely protected from mortality when challenged with a myocarditic strain of CB3. Histologically no inflammatory lesions were found in the heart. This was corroborated using immune histological techniques with monoclonal antibodies against lymphocyte subsets. Even at a dose of 0.16 ng a delayed mortality was observed. Neutralizing antibody titres rose to 512, thus ensuring a circulating level well above that considered protective. It is suggested that vaccination might be a possible way of prophylaxis for myocarditis and even dilated cardiomyopathy, the latter presently being the chief cause of heart transplantation. By persistence or triggering of autoimmune phenomena Coxsackie virus is incriminated as the first step in pathogenesis.

The distribution of 109Cd was studied 4 days post CB3-inoculation and 10 min after intravenous injection of 0.21 microgram of Cd/kg body weight. Whole-body autoradiography results showed that the distribution of 109Cd is greatly changed during this viral infection. This newly discovered distribution was mainly visible as a greatly increased accumulation in the renal and adrenal cortices. After impulse counting of selected organs it was found that the normal accumulation of 109Cd in the kidneys (184,354 +/- 30,961 c.p.m.) was increased by 47% (P less than 0.05) during CB3 infection (270,503 +/- 54,780 c.p.m.). In contrast to healthy animals, some infected mice showed accumulation of 109Cd in the spleen. These results show for the first time that an invading micro-organism can change the distribution of an environmental pollutant.

However, the mechanisms of CA induction are not well known. In this study we investigate the role of direct viral induction of CA in CVB3 myocarditis. A/J mice were infected with the Woodruff strain of CVB3 and treated with WIN 54954 for 5 days thereafter. WIN 54954, a compound that inhibits early events of picornavirus infection, is known to dramatically reduce mortality in murine CVB3 myocarditis without abrogating systemic or myocardial inflammation. Presence of viral RNA (in situ hybridization), CA (TUNEL method) and histopathology were studied in transverse ventricular sections at day 7 post infection (n = 8 treated and n = 8 non-treated). The proportion of cardiomyocytes containing viral RNA was 89% lower in WIN 54954 treated mice when compared with non-treated mice (0.29 +/- 0.56% vs 2.76 +/- 1.65%, p = 0.003). Treatment also reduced the amount of CA by 52% compared with non-treated mice (0.20 +/- 0.06% vs 0.42 +/- 0.06%, p < 0.001). The reduction of CA by WIN treatment did not result in any increase of necrosis, in fact treatment reduced the area of necrotic lesions by 77% (2.51 +/- 1.64% vs 11.10 +/- 8.76%, p = 0.028). Taking the results of the reduced CA, necrosis and viral RNA with no effect on inflammation into account, our findings suggest the importance of direct viral effect in cardiomyocyte damage by both apoptosis and necrosis in CVB3 myocarditis.

Detection methods for a wide range of CoVs are needed, to understand viral evolution, host range, transmission and maintenance in reservoirs. A new concept, "Multiprobe QPCR", which uses a balanced mixture of competing discrete non- or moderately degenerated nuclease degradable (TaqMan) probes was employed. It provides a broadly targeted and rational single tube real-time reverse transcription PCR ("NQPCR") for the generic detection and discovery of CoV. Degenerate primers, previously published, and the new probes, were from a conserved stretch of open reading frame 1b, encoding the replicase. This multiprobe design reduced the degree of probe degeneration, which otherwise decreases the sensitivity, and allowed a preliminary classification of the amplified sequence directly from the QPCR trace. The split probe strategy allowed detection of down to 10 viral nucleic acid equivalents of CoV from all known CoV groups. Evaluation was with reference CoV strains, synthetic targets, human respiratory samples and avian fecal samples. Infectious-Bronchitis-Virus (IBV)-related variants were found in 7 of 35 sample pools, from 100 wild mallards (Anas platyrhynchos). Ducks may spread and harbour CoVs. NQPCR can detect a wide range of CoVs, as illustrated for humans and ducks.

The principles of a PCR enhanced immunoassay (PIA) are described. The method combines solid phase serological techniques with the PCR, providing a versatile and sensitive method for antibody detection. By linking the antigenicity of virus particles with their content of nucleic acid, the method provides new possibilities for virus serology: for example, antibody specificity can be coupled to viral sequence in patients with chronic infections caused by highly variable viruses such as HIV and HCV. An application of the PIA technique is described for the detection of anti-enterovirus IgM. IgM is captured to anti-human IgM-coated microwell plates. The anti-enterovirus IgM is allowed to bind crude enterovirus antigen. Bound virus is heat denatured and the released RNA is used as a template for reverse transcription PCR (RT-PCR) amplification. Amplicons are detected by hybridisation to an affinity labelled probe in a microwell colorimetric assay. In a pilot study, 18 serum specimens from patients with enterovirus infections were examined. Using a mixture of ten crude enterovirus antigens, the frequency of IgM positivity was 6/18 (33%). Titres between 1/500 and 1/100,000 were recorded. Predominantly type-specific antibodies were detected. The results were compared with a procapsid enterovirus radioimmunoassay (RIA). After further optimisation, the PIA has the potential to be a clinically useful assay for the detection of antiviral antibodies.

Thirteen of the 24 (54%) patients reported symptoms of acute infection within two months before diabetes was diagnosed. The mean age was 8.5 years and 15 (63%) of the patients were girls. No clear seasonal variation in onset was seen. Coxsackie B (CB)-virus-specific IgM responses were detected by reverse radioimmunoassay (RIA) in 16 of the 24 (67%) patients on the day of diagnosis of IDDM. The highest titre was usually recorded at that time, but with some the highest titre was found with a second serum obtained three to seven weeks after diagnosis. Thereafter the titres declined, and after six months IgM was detected only in a few patients. Thirteen patients displayed monotypic IgM responses, whereas three patients showed ditypic responses. Among the former, IgM was recorded against Coxsackie B4 (CB4) in four, B5 (CB5) in three, B1 (CB1) in two, B2 (CB2) in two, and B3 (CB3) in two patients. The ditypic responses were against CB2 and CB3, CB3 and CB4, and CB5. No CB-virus-specific IgM was detected in sera, found during the same period, from age-matched nondiabetic children without evidence of infection. In neutralisation (NT) tests, antibodies to the homotypic virus were found in 12 of the 16 diabetic patients showing CB-virus-specific at the time of diagnosis. A significant rise in NT titre was demonstrated in three of these patients. No significant clinical difference was noted between IgM positive and IgM negative patients.(ABSTRACT TRUNCATED AT 250 WORDS)

The aetiological panorama varies in different parts of the world as well as over time. Thus, virological first-line diagnostics must be adapted to the current epidemiological situation and to the individual patient history, including recent travels. This review focuses on the diagnostics and treatment of viral CNS infections in the immunocompetent host from a Northern European perspective. Effective vaccines are available for viruses such as poliovirus and tick-borne encephalitis virus (TBEV) and for the childhood diseases morbilli (measles), rubella (German measles), parotitis (mumps) and varicella (chickenpox). However, cases do appear due to suboptimal immunization rates. In viral CNS infections, epidemiological surveillance is essential for establishing preventive strategies and for detecting emerging viruses. Knowledge of the possibilities and limitations of diagnostic methods for specific viral CNS infections is vital. A positive cerebral spinal fluid (CSF) polymerase chain reaction (PCR) finding is usually reliable for aetiological diagnosis. The demonstration of intrathecal antibody synthesis is useful for confirming the aetiology in a later stage of disease, hitherto sufficiently evaluated in herpes simplex encephalitis (HSE) and tick-borne encephalitis (TBE). Despite improved virological and differential diagnostic methods, aetiology remains unknown in about half of the cases with suspected viral encephalitis. Antiviral treatment is available chiefly for infections caused by herpesviruses, and acyclovir (aciclovir) is the drug of choice for empirical therapy in suspected viral encephalitis. However, randomized, controlled antiviral trials have only been conducted for HSE, while such studies are lacking in other viral CNS infections. Viral cytolysis and immune-mediated mechanisms may contribute to varying extents to neurological damage. Although the brain damage is believed to depend, to a varying degree, on the intrathecal host immune response, the use of corticosteroids in viral CNS infections is scarcely studied, as is specific treatment for neuroinflammation. Improved antiviral and immunomodulating treatment is desirable. Since neurological sequelae are still abundant, follow-up after severe viral CNS disease must include a neuropsychological assessment and an individually adapted rehabilitation plan.
