Conclusions drawn from the post-mortem examination of 226 subjects who died of cerebral haemorrhage are presented. There were slightly more women than men (53%) in the series. Arterial hypertension (68%) was the main cause of death, while renal disease, leukaemia, angioma of the pons, and embolism due to bacterial endocarditis were also observed. The most frequently noted sites are listed. Since cerebral haemorrhage follows the rupture of one or more already damaged deep arteries, as assessment was made of the part played by vascular lesions. 13 cases due to leukaemia and 35 to rupture of aneurysms of the polygon of Willis were discarded. In only 20 cases out of 138 in which convincing microscopic evidence of the vascular situation could be obtained was there an absence of significant alterations. The remaining cases consisted of serious hyalinosis (56%), fibrinoid necrosis (13%), and siderocalciosis (12%). An account is also given of the special pathogenetic conditions applicable to cerebral haemorrhage associated wtih serious gastrointestinal haemorrhage or recent myocardial infarct.

Pitfalls in the clinical diagnosis of the aetiology of acquired tricuspid incompetence in children were exemplified in five patients. In three of them acute staphylococcal endocarditis, the cause of the valve defect, was obscured during life by co-existing sickle cell haemoglobinopathy, acute leukaemia and rheumatic mitral valvulitis, respectively. The fourth and fifth patients had clinical features suggestive of right ventricular endomyocardial fibrosis but necropsy revealed that the tricuspid incompetence was caused by dilated cardiomyopathy and constrictive pericarditis respectively. This series illustrates the need to suspect bacterial endocarditis if a child presents with signs of infection and valvular incompetence, and also dispels the widespread belief that pericardial constriction does not cause tricuspid incompetence.

Due to the great number of different micro-organisms present, the oral cavity is an important source of infection. Infections caused by these micro-organisms can occur as local infections of the oral mucous membrane, local infections of the soft tissues or the bones following surgical intervention, or endocarditis due to bacteraemia following dental surgery. In the therapy of periodontal diseases, the application of antiseptic solutions is indicated to inhibit or reduce plaque accumulation. Povidone-iodine (PVP-I) solution will reduce inflammation and the progression of periodontal disease. The application of antiseptics in the oral mucous membrane is also indicated to prevent wound infections following surgical intervention in patients with leukaemia, AIDS, immunosuppressant therapy and patients undergoing anti-neoplastic radiation or chemotherapy. Some trials on the antibacterial efficacy of PVP-I in vivo showed reduction factors of log 2-3. PVP-I may therefore be recommended as an oral antiseptic. The irrigation of the gingival sulcus with an antiseptic solution is a useful complement to antibiotic prophylaxis in patients at risk of bacterial endocarditis. Many trials on the effectiveness of PVP-I on dental extraction bacteraemia have shown a significant benefit in the active group in comparison with the control group.

The diagnosis and management of infectious complications associated with injection drug use (IDU) are among some of the more challenging aspects of working with substance abusing populations. As the population of injection drug users age, we expect the number and severity of these complications to increase. Commonly seen infections, such as bacterial endocarditis and bacterial infections of bones, joints, and soft tissue, are now frequently complicated by concurrent immunodeficiency. Parenterally and sexually transmitted viral hepatitis is responsible for significant IDU morbidity and mortality. The human leukemia/lymphoma virus types I and II are increasing in prevalence in the IDU with uncertain long-term clinical effects. Immune dysfunction has been described in the IDU for decades, but the impact of host immune compromise on the transmission and the course of HIV-1 has yet to be fully appreciated. The integration of the treatment of substance abuse and its concurrent psychiatric disorders with the management of infectious complications, including immunodeficiency, promises to improve patient compliance with possible savings of overall medical costs.

Human brucellosis is an important animal transmitted disease of man. Although, the cases have been recorded all over the world, the prevalence is higher in developing countries. Lack of sufficient knowledge about the disease among the physicians, its under-diagnosis or misdiagnosis and absence of effective prevention and management strategies are attributed to the widespread of the disease. Increase in the occurrence of animal brucellosis has also resulted indirectly in an increase in the prevalence of human infection. Absence of characteristic clinical symptoms, chronic nature of the infection and difficulty in isolation of the causal agent from the patients make the diagnosis of the disease more difficult. The serological tests employed for diagnosing human brucellosis vary in terms of their sensitivity and specificity. Therefore, a combination of serological tests is desirable. Currently no vaccine is available against human brucellosis, which could check the spread of the disease effectively. It is suggested that clinicians investigate the cases of pyrexia of unknown origin (PUO) for brucellosis. It is desirable that specimens from cases of tuberculosis, typhoid, rheumatoid arthritis, urogenital infections, kala-azar, cirrhosis, bacterial endocarditis, leukemia and filariasis should also be screened for brucellosis in man. The cases of meningitis of unestablished etiology as the cases of human brucellosis are often misdiagnosed as cases of typhoid or tuberculosis.

Surface enhanced laser desorption ionization-time of flight is a mass spectrometric-based method that requires a minimal amount of sample for analysis and can be used for high-throughput screening. It has been used to discover serum or tissue protein signatures and biomarkers for infectious diseases in the fields of virology (hepatitis B and C viruses, severe acute respiratory syndrome, HIV-1, human T-cell leukemia virus-1 and BK virus), parasitology (trypanosomiasis) and bacteriology (intra-amniotic inflammation, tuberculosis and bacterial endocarditis). The protein signatures, or biomarkers, can be used to diagnose infection, predict disease states and to inform on disease processes. Careful attention to experimental design, sample handling and storage, and the use of appropriate internal controls is crucial to success.

Infective endocarditis (IE) is associated with high morbidity and mortality despite advances in antibiotic and surgical treatment. Systemic embolism occurs in up to 49% of IE patients and may involve the major arteries, limb arteries, viscera and the central nervous system. In this report we describe a 60-year-old female patient with a history of acute lymphoblastic leukaemia who presented with endocarditis manifesting as stroke, acute limb ischaemia and meningitis. Early diagnosis is essential since treatment lowers the risk of embolism, with most events occurring within 2 weeks of treatment initiation.
