Although there has been a significant decline in elective surgery for peptic ulcer disease with the introduction of H-2 blocker, the incidence of peptic ulcer perforation has remained relatively unchanged over the years. The mortality rate from perforated peptic ulcer remains high as more perforations occur in the elderly...

Intensive care has undergone rapid technological advancement in recent years enabling complex treatment of patients of advanced age and/or with advanced chronic diseases underlying their acute medical problems. New interventions have been introduced with success determined by their ability to save lives. This article is available only as a PDF....

Technological advances over the last 30 years have had an enormous impact on the way in which medicine is delivered today. This is particularly so in the specialty of intensive care where intensivists possess the necessary knowledge and tools to prolong life in many situations where patients would previously...

Despite intensive therapeutic efforts, both the incidence and mortality of gastrointestinal complications after cardiac surgery employing cardiopulmonary bypass (CPB) have not decreased during the last two decades. Gastric bleeding, ischaemic bowel disease, gallbladder disease, and pancreatitis are reportedly the most common complications. This article is available only as a PDF....

Pulmonary arterial hypertension (PAH) is an uncommon but serious and debilitating disorder seen in children and adults. By definition, it is an elevation of the pressure in the pulmonary artery to above a mean of 25 mmHg at rest, or 30 mmHg during exercise. This article is available only as...

Rapid urbanisation and increasing affluence have improved the socioeconomic status of Asians. This, however, has brought with it new socioeconomic and medical problems resulting from the urbanised lifestyles entrenched in these newly industrialised economies.

Influenza is a major cause of morbidity and mortality worldwide. Morbidity in the working age group gives rise to frequent doctor visits and considerable sickness absence from work. Influenza in the elderly population and in high-risk groups results in hospitalisations and deaths due to complications of pneumonia. This article is...

Human isolates of group G streptococci (GGS) that form large colonies are similar to group A streptococci (GAS) in terms of virulence and cause a range of serious infections. These included infective endocarditis which had been emphasised in older reports1 but was found to be uncommon in later studies. This...

Singapore is facing a rapidly ageing population. Osteoporosis, which is an age-related illness, will become an increasing problem. Osteoporotic hip fracture, because of the need for hospitalisation and surgery, represents an important economic burden to society, in addition to its medical morbidities and social implications upon the patient and...

Increasing life expectancy and ageing of the “post-war baby boomer” generation have led to the rapidly ageing demographic of many Asian countries. Singapore’s elderly population above the age of 65 will rise from 7.5% in 2002 to 18.9% by the year 2030. This article is available only as a PDF....

Pulmonary hypertension (PHT) is seen in 0.5% to 14% of systemic lupus erythematosus (SLE) patients and is associated with a grave prognosis.
