Delayed diagnosis of scrofuloderma misdiagnosed as a bacterial abscess.

An 82-year-old woman presented with a four-month history of an ulcerative plaque overlying her left neck. This lesion had developed as a subcutaneous nodule, gradually increased in size, and evolved into ulcers. Before visiting our Dermatology clinic, the patient had been diagnosed as having a bacterial abscess, but treatments with antibiotics were unsuccessful.

Analysis of cardiovascular risk factors and metabolic syndrome in korean patients with psoriasis.

Background: In previous studies, psoriasis has been reported to be associated with metabolic syndrome.

Objective: The purpose of this study was to evaluate risk factors for metabolic syndrome in psoriasis patients and to compare the prevalence of metabolic syndrome in psoriasis and control groups.

Methods: All patients (n=490) and controls (n=682) were investigated for cardiovascular risk factors, including central obesity, hypertension, fasting plasma glucose levels, and blood levels of triglycerides and high-density lipoprotein (HDL).

Porphyrins bearing stable meso-alkylidenyl double bonds. A new family of nonplanar porphyrinoids.

[Structure: see text] Unique core-modified porphyrinoids, such as oxabenziporphyrins, oxapyriporphyrins, and thiapyriporphyrins, bearing exocyclic C-C double bonds at meso-positions, have been synthesized and characterized. The synthesis was accomplished by utilizing typical "3+1"-type condensation. Two different stable tautomeric forms were isolated, and the two tautomeric forms can be interconvertible upon treatment with base.

Coumarin-strapped calix[4]pyrrole: a fluorogenic anion receptor modulated by cation and anion binding.

A new strapped calix[4]pyrrole containing a fluorophore as part of the strap has been synthesized and characterized. Association constants with various anions have been determined using both fluorescence titration and isothermal titrations calorimetry (ITC). The two sets of association constants were found to be in good agreement with one another.
