Review Case ReportsThe alien hand sign--case report and review of the literature.
The alien hand sign refers to a group of signs which include a feeling that the hand is foreign together with autonomous activity, as if the hand is driven by an external agent. These features are commonly associated with frontal and callosal lesions. We report the alien hand sign in a man with left medial cortical infarct, presenting with autonomous grasping and groping with his right upper limb, denial of ownership of his limb, and dissociative phenomena including self restriction and intermanual conflict.

Review Case ReportsHyperthyroidism with gynaecomastia as the initial complaint: a case report.
Although gynaecomastia is a well-documented manifestation among male patients with hyperthyroidism, it is extremely rare to present as the initial or chief complaint in a subject with undiagnosed hyperthyroidism. We report a case of a 38-year-old Chinese man presenting with painful enlargement of both breasts of one month's duration. Examination revealed bilateral tender gynaecomastia. ⋯ Hyperthyroidism was confirmed biochemically. Treatment of thyrotoxicosis resulted in resolution of the gynaecomastia. This case report demonstrates that gynaecomastia may predominate over the commonly recognised, more manifest and urgent symptoms of hyperthyroidism.

Review Case ReportsA case series of ocular disease as the primary manifestation in sarcoidosis.
Sarcoidosis is an idiopathic, systemic, non-caseating, granulomatous disease with protean clinical manifestations. This disease is highly prevalent in the southern states of United States of America, especially among African-Americans, but uncommon among Asians. Though sarcoidosis concerns physicians of virtually all specialties, it is particularly important to ophthalmologists since a significant number of patients will seek initial medical examination because of ocular disease. ⋯ We report here 4 patients with active sarcoidosis who presented to us with ocular symptoms as the first and primary manifestation of the disease. All 4 patients developed symptoms and signs of systemic sarcoidosis at a later date. The ocular manifestations included simultaneous bilateral chronic granulomatous iridocyclitis, intermediate uveitis, posterior uveitis characterised by vasculitis with candle wax drippings, and optic nerve head granuloma.

The Western Pacific region has seen rapid recent economic development but variation in the provision and organisation of intensive care units (ICUs) between different countries remains. While Japan, Australia, New Zealand, Singapore, Taiwan, Korea and Hong Kong have well developed intensive care facilities, in other countries the more limited funding for healthcare can be reflected by differential availability of modern medical technology between the public and private sectors. Other factors important to intensive care include physician training, availability of other staff and whether intensive care is delivered in "open" or "closed" units. ⋯ Future development of intensive care in the region will parallel economic development. In most countries increasing patient expectations, ageing populations and "Western" diseases will increase demand for intensive care services. Only a few countries currently have recognised programmes of training and certification in intensive care but as more adopt this process it should lead to a clearer recognition and acceptance of the role of the intensivist.

Septic shock is a major cause of death among patients in intensive care units. It has a mortality rate of 20% to 80%. The clinical syndrome of septic shock is characterised by hypotension, hyporesponsiveness to vasoconstrictors and volume depletion which will then lead to multiorgan dysfunction and death. ⋯ Inhibition of NO synthase, the enzyme responsible for NO production, has been proposed as a new therapy for septic shock. However, experimental reports have provided conflicting results, demonstrating both beneficial and detrimental effects. A brief review of the role of NO in septic shock and the possible use of NO synthase inhibitors as potential therapeutic agents is presented here.
