Pityriasis lichenoides Chronica is a cutaneous disorder of unknown etiology and characterized pathologically by vasculitis and clinically by its marked chronicity and lack of specific treatment. Emollient-phototherapy is a recently introduced effective treatment for psoriasis. The authors treated 3 patients with pityriasis lichenoides chronica by the emollient-phototherapy technic with quite satisfactory results.

Behcet's disease is a systemic vasculitis that is characterized mainly by recurrent oral and genital aphthous ulcers, uveitis, and skin findings. Its neurological manifestations are well recognized. Recurrent meningitis in Behcet's disease is exceptional. We describe herein the case of a 31-year-old man who presented with recurrent aseptic meningitis without any specific cause. A few years later he developed oral and genital ulcers, and uveitis. Behcet's disease should always be considered in a differential diagnosis of recurrent aseptic meningitis without viral infection, particularly in the context of multisystem manifestations.

A prospective randomised trial was performed to assess the diagnostic accuracy according to the time interval and the efficacy of endoscopic injection of hypertonic saline-epinephrine(HS- E)solution, consisting of 3.5% sodium chloride with 0.0045% epinephrine, for actively bleeding peptic ulcers, exposed vessel or blood clot on ulcer bed, or Mallory-Weiss tear. Over 24 month, emergency endoscopy in 180 patients admitted for upper gastrointestinal hemorrhage identified 51 patients with nonvariceal hemorrhage. The causes of bleeding were; gastric ulcer in 32; duodenal ulcer in 13; gastric cancer in 4; Mallory-Weiss tear in 2. With this method, the hemostatic effect was permanent in 40 cases(84.3%), temporary in 9 cases(11.8%), and failed in 2 cases(3.9%). By applying this method, the rate of emergency operation for patients with bleeding from the upper gastrointestinal tract was significantly reduced from 20.0% (8/40)to 3.9%(2/51)(p<0.05). Emergency endoscopy in acute UGI bleeding increases the accuracy of detection of actual bleeding sites(p<0.05), but if the endoscopic procedure was performed within 48 hours, the hemostatic rate was not affected(p<0.05). We concluded that hypertonic saline-epinephrine injection method could provide a simple maneuver with reasonable cost, high safety, and satisfactory hemostatic efficacy in the treatment of nonvariceal upper gastrointestinal bleeding.

Currently, endoscopic injection sclerotherapy(EIS) is the most widely used method for treating and eradicating acutely bleeding esophageal varices in repeated sessions, but may be associated with some undesirable local and systemic complications. (continue...)

Internal capsular genu infarcts infrequently cause cognitive impairment and behavioral changes, and little is known about the underlying mechanism. Using diffusion-tensor imaging (DTI) and the fractional anisotropy (FA) index in the region of interest (ROI) and ipsilesional frontal cortex, we evaluated two patients with internal capsular genu infarction who presented with frontal dysfunction and cognitive impairment. The reported findings help to elucidate the mechanism underlying cognitive deterioration in internal capsular genu infarction.

Neurilemmoma is a benign, solitary tumor which may occur from the nerve sheath of the peripheral, sympathetic and cranial nerves. Although it occurs most frequently in the head and neck region, especially in the acoustic nerve and the vagus nerve, the neurilemmoma of the brachial plexus is rare. We have experienced a case of neurilemmoma in the brachial plexus. Surgical excision was performed by anterior supraclavicular approach. The mass was removed completely, sparing the nerve function. We report this case with literature review.

Direct exposure of renal tubular brush-border membranes (BBM) to free cadmium (Cd) causes a reduction in phosphate (Pi) transport capacity. Biochemical mechanism of this reduction was investigated in the present study. Renal proximal tubular brush-border membrane vesicles (BBMV) were isolated from rabbit kidney outer cortex by Mg precipitation method. Vesicles were exposed to 50~200 muM CdCl2 for 30 min, then the phosphate transporter activity was determined. The range of Cd concentration employed in this study was comparable to that of the unbound Cd documented in renal cortical tissues of Cd-exposed animals at the time of onset of renal dysfunction. The rate of sodium-dependent phosphate transport (Na+-Pi cotransport) by BBMV was determined by 32P-labeled inorganic phosphate uptake, and the number of Na+/-Pi cotransporters in the BBM was assessed by Pi-protectable 14C-labeled phosphonoformic acid ((14C)PFA) binding. The exposure of BBMV to Cd decreased the Na+-Pi cotransport activity in proportion to the Cd concentration in the preincubation medium, but it showed no apparent effect on the Pi-protectable PFA binding. These results indicate that an interaction of renal BBM with free Cd induces a reduction in Na+-Pi cotransport activity without altering the carrier density in the membrane. This, in turn, suggest that the suppression of phosphate transport capacity (Vmax) observed in Cd-treated renal BBM is due to a reduction in Na+-Pi translocation by existing carriers, possibly by Cd-induced fall in membrane fluidity.

High signal intensity on diffusion-weighted image (DWI) at the site of venous occlusion has previously been reported in cerebral venous thrombosis (CVT). The frequency and diagnostic value of these signal changes in CVT were unknown. Some authors suggest that the presence of high signal intensity on DWI in occluded veins might help diagnose CVT and suggest low rate of recanalization. We experienced two cases of CVT with high signal intensity at the site of intravascular clot on DWI.
