[Can prevention of hepatitis B following exposure to hepatitis virus be improved by immediate administration of HB immune serum?].

Sixty-five medical personnel thought to be exposed to hepatitis-B-surface antigen (HBs) positive material by accidental needle stick were treated with 4 ml hepatitis B-immunoglobulin (SRK, Swiss Red Cross). The prophylaxis was started as soon as possible, mostly within an hour or two. 56 patients were followed up with clinical and serological tests at monthly intervals for 9 months. In individuals exposed to HBs-antigen negative material, signs of HBV-infection could be detected only in one. In 36 cases potentially infectious material proved to be HBs-Ag positive. Six of the medical personnel (16.7%) had signs of hepatitis B-virus infection. One individual (2.8%) developed clinical hepatitis type B. Three (8.3%) converted to active hepatitis B markers (anti-HBs and/or anti-HBc) without clinical symptoms. Two of four who already had anti-HBs before exposure developed antibodies to HBc afresh at three- and six-month intervals. These serological conversions and the one case of clinical hepatitis developed despite the fact that HB-Ig was given in nearly all cases within one hour of exposure. The incubation period was 5-8 months. It is concluded that even rapid prophylaxis with HB-Ig after needle stick exposure does not afford 100% protection. It is urged that any passive prophylaxis with HB-Ig in exposed personnel should be complemented by active hepatitis B immunization.

[The irritable colon].

Irritable bowel syndrome is the most common gastrointestinal disorder. The motility disturbance determines the clinical presentation and two types are distinguished, i.e. spastic colon and painless diarrhea. The motor dysfunction is probably related to abnormal myoelectric activity of the colon. In contrast to healthy persons, slow electrical waves with a frequency of 3 cycles per minute predominate. Although irritable bowel syndrome is a disease of unknown etiology, psychological factors and fibre-deficient diet may be involved. The work-up should take into account the fact that irritable bowel syndrome remains a diagnosis by exclusion. The effect of current therapy on the chronic-relapsing course of this disease is only slight.

[Actinobacillus actinomycetemcomitans endocarditis. A case report and literature review].

A case of subacute endocarditis caused by Actinobacillus actinomycetemcomitans is reported. After successful treatment with ampicillin and tobramycin, the destroyed aortic valve was replaced and a communication between an aneurysm of sinus of Valsalva and the right atrium was closed. A further 23 well documented cases from the literature are reviewed.

Prevention of hepatitis B virus transmission by the gastrointestinal fibrescope. Successful disinfection with an aldehyde liquid.

In a prospective study we examined the efficacy of a standardized disinfection method in preventing the transmission of hepatitis B virus by the gastrointestinal fibrescope. Four HBSAg- and Dane particle-positive patients who have been endoscoped served as possible sources of hepatitis B virus infection. We cleaned the instrument with a 10% aldehyde liquid and used it immediately thereafter in 10 HBSAg-negative patients. Eight of them were followed-up for 7 months after the endoscopic procedure. None of them showed serological evidence of an endoscopically transmitted hepatitis B virus infection. It is concluded that disinfection with an aldehyde liquid is effective in preventing the transmission of hepatitis B virus by the fibrescope.

Acute viral hepatitis B with bridging necrosis: a follow-up study.

Forty patients with bridging necrosis (BN) on biopsies taken during the course of acute viral hepatitis B were included in a prospective study to assess the prognostic significance of this lesion. Of the 22 patients with complete clinical, biochemical and histological follow-up (histological follow-up 5-33 months), only two failed to eliminate HBs- and HBe-antigen in serum, a finding paralleled by transition to chronic active hepatitis and by the persistence of focal HBc- and HBs-antigen expression in liver tissue. Nineteen of 22 patients showed complete histological healing; one developed inactive cirrhosis. It is concluded that, in the setting of acute viral hepatitis B, the histological lesion of BN is of no particular prognostic significance, and that transition to chronic liver disease is much less frequent than has been assumed from previous studies of etiologically heterogeneous patient populations. Markers of poor prognosis are the failure of serological elimination of HBs- and HBe-antigen and the persistence of spotty expression of HBc- and HBs-antigen on immunofluorescence histology.
