In open wounds of the hand that have exposed bone or tendons, management may be difficult. Compared with conventional cutaneous pedicle flaps, the fascial radial flap transfer has several advantages : (1) one operation is required by one operating team reliably and easy to perform, (2) the appearance is not bulky, (3) the donor area is closed primarily, and (4) the hand is free for early motion of the shoulder and the elbow. One potential disadvantage is the permanent loss of the contribution of the radial artery to the circulation of the hand. One case of the fascial radial flap transfer was performed at the Department of Orthopaedic Surgery of Hanyang University Hospital, and satisfactory result was obtained.

Takayasu's arteritis is briefly as an inflammatory process of unknown etiology occuring dominantly in young female most commonly involving the great vessels arising from the aortic arch. The disease process results in stenosis and obliteration of involved vessels. Syncope in Takayasu's arteritis is known to result from decreased blood flow to brain because of stenosing blood vessels. We herein describe a case of paroxysmal atrioventricular block in a 40-year old man with Takayasu's arteritis. The patient presented with spontaneous recurrent syncope associated with paroxysmal AV block. Carotid sinus pressure repeatedly induced paroxysmal AV block and syncope. Carotid sinus pressure after pretreatment of atropine failed to induce AV block or syncope. Coronary angiogram was normal. We concluded that syncope in this patients was attributed to carotid hypersensitivity rather than decreased blood flow to the brain due to vessel stenosis.

We investigated the effect of alpha-adrenergic and cholinergic receptor agonists on Ca2+ current in adult rat trigeminal ganglion neurons using whole-cell patch clamp methods. The application of acetylcholine, carbachol, and oxotremorine (50 muM each) produced a rapid and reversible reduction of the Ca2+ current by 17+/-6%, 19+/-3% and 18+/-4%, respectively. Atropine, a muscarinic antagonist, blocked carbachol-induced Ca2+ current inhibition to 3 +/- 1%. Norepinephrine (50 muM) reduced Ca2+ current by 18 +/- 2%, while clonidine (50 muM), an alpha2-adrenergic receptor agonist, inhibited Ca2+ current by only 4 +/- 1%. Yohimbine, an alpha2-adrenergic receptor antagonist, did not block the inhibitory effect of norepinephrine on Ca2+ current, whereas prazosin, an alpha1-adrenergic receptor antagonist, attenuated the inhibitory effect of norepinephrine on Ca2+ current to 6 +/- 1%. This pharmacology contrasts with alpha2-adrenergic receptor modulation of Ca2+ channels in rat sympathetic neurons, which is sensitive to clonidine and blocked by yohimbine. Our data suggest that the modulation of voltage dependent Ca2+ channel by norepinephrine is mediated via an alpha1-adrenergic receptor. Pretreatment with pertussis toxin (250 ng/ml) for 16 h greatly reduced norepinephrine- and carbachol-induced Ca2+ current inhibition from 17 +/- 3% and 18 +/- 3% to 2 +/- 1% and 2 +/- 1%, respectively. These results demonstrate that norepinephrine, through an alpha1-adrenergic receptor, and carbachol, through a muscarinic receptor, inhibit Ca2+ currents in adult rat trigeminal ganglion neurons via pertussis toxin sensitive GTP-binding proteins.

Thallium-201 brain SPECT is utilized in the diagnosis of brain tumor especially in cases where CT or MRI findings alone cannot differentiate malignant lesion from benign. Recently we came across two cases of positive T1-201 brain SPECT in clinically suspected brain tumor patients that turned out to be hemorrhagic cerebral infarction instead on biopsy. The findings in these cases demonstrate that thallium-201 accumulation may occur by the breakdown of the blood-brain barrier and phagocytic cell infiltration in the liquefaction stage of infarction.

After an outbreak of H1N1 influenza A virus infection in Mexico in late March 2009, the World Health Organization raised its pandemic alert level to phase 6, and to the highest level in June 2009. The pandemic H1N1/A influenza was caused by an H1N1 influenza A virus that represents a quadruple reassortment of two swine strains, one human strain, and one avian strain of influenza. After the first case report of H1N1/A infection in early May 2009, South Korea was overwhelmed by this new kind of influenza H1N1/A pandemic, which resulted in a total of 700,000 formally reported cases and 252 deaths. In this article, clinical characteristics of victims of H1N1/A influenza infection, especially those who developed pneumonia and those who were cared for in the intensive care unit, are described. In addition, guidelines for the treatment of H1N1/A influenza virus infection victims in the ICU, which was suggested by the Korean Society of Critical Care Medicine, are introduced.

VEP is an objective method for the evaluation of macular function and optic nerve disease, but its large inter and intraindividual variation prevented clinical and experimental application. We recorded a relatively stable VEP A wave in pigmented rabbits with cortical electrode and following results were obtained. The amplitude of VEP A wave was 97.8 +/- 29.8 micro V and latent time was 52.2 +/- 6.9 msec. Inter- and intraindividual variation of VEP latent time was much smaller than that of VEP amplitude. So latent time of VEP A wave may be a good indicator in evaluation of pharmacologic and toxicologic experiment of systemically administered drug.
