 Today, more than 10 years and 2000 articles since human herpesvirus 8 was first described by Chang et al., novel insights into the transmission and molecular biology of HHV-8[1] have unveiled a new spectrum of diseases attributed to the virus. The association of HHV-8 with proliferative disorders – including Kaposi's sarcoma, multicentric Castleman disease and primary effusion lymphoma – is well established. Other aspects of HHV-8 infection are currently the subject of accelerated research. Primary HHV-8 infection may manifest as a mononucleosis-like syndrome in the immunocompetent host, or in various forms in the immunocompromised host. The association of HHV-8 with primary pulmonary hypertension was observed by Cool et al. in 2003, but six clinical trials evaluating the role of HHV-8 in pulmonary hypertension have not been able to replicate this intriguing observation. It has been speculated that HHV-8 may secondarily infect proliferating endothelium in patients with pulmonary hypertension. HHV-8 epidemiology, modes of transmission, new spectrum of disease and treatment are presented and discussed.

 Background: Maintaining a death register and holding staff discussions about patients who died can aid the physician in audit and research, which will lead to improved care of the terminally ill and the bereaved and to the development of prevention strategies. These issues are important for students and residents as well.

Objectives: To review the value of mortality-case discussions in primary care clinics, particularly teaching clinics.

Methods: The clinic death register, instituted in 1998, includes age, gender, cause of death, place of death, relevant illnesses, and support provided to the patient before the death. In the half-yearly sessions, the data are reviewed, and individual cases that had an emotional impact on the staff, or information that can bring about changes in future care are discussed by the clinic staff and trainees.

Results: In our clinic 233 deaths occurred during a 6 year period (1998–2003). The crude all-cause mortality rate was 7.1/1000. The median age was 80 years old. Neoplastic causes were slightly more frequent than cardiovascular causes of death. Only 15% died at home; 20% lived alone and 70% lived with a spouse or family members before the death. Topics discussed in the mortality review meetings include identifying pre-suicidal patients, when to hospitalize the sick elderly, dealing with the anger of bereaved families, and ensuring proper home care for terminal patients.

Conclusions: We recommend keeping a death register and conducting mortality review sessions in order to improve the quality of care, emotional support of the staff, and training students and residents about the complex issues surrounding the death of patients.

 Background: Microvascular complications of diabetes contribute significantly to the disease morbidity. The metabolic syndrome is very common among subjects with diabetes and is a very important risk factor for macrovascular complications. However, its contribution to the microvascular complication has not been assessed.

Objectives: To assess the risk of microvascular complications associated with the metabolic syndrome in diabetes subjects.

Methods: The study group comprised 415 diabetic subjects attending a primary care clinic. The prevalence of microvascular complications was compared between 270 diabetic subjects with metabolic syndrome (NCEP-III criteria) and 145 diabetic patients without.

Results: We found that as a group, diabetic subjects with metabolic syndrome had significantly higher frequency of microvascular-related complications than diabetic subjects without the syndrome (46.6% and 26.8% respectively, P = 0.0005). These include microalbuminuria (41.5% vs. 23.9%, P = 0.013), neuropathy (10.4% vs. 7.5%, P = 0.38), retinopathy (9.6% vs. 4.1%, P = 0.046) and leg ulcers (7.9% vs. 2.8%, P = 0.044). After adjustment for age, gender, glycemic control, disease duration, lipid profile and blood pressure, metabolic syndrome was associated with a significantly higher risk of microvascular complications: odds ratio (95% confidence interval) for nephropathy 2.27 (1.53–3.34), neuropathy 1.77 (0.79–4.0), retinopathy 3.42 (1.2–9.87), and leg ulcers 3.57 (1.08–11.95).

Conclusions: In addition to hyperglycemia and disease duration, the metabolic syndrome is a significant risk factor for the development of microvascular complications in diabetic subjects.
