A 40-year-old woman had had, for 5 years, episodes of pallor and blue discoloration of the fingers and toes after cooling and emotional exertion. During these 5 years she also had intolerance to warming of the feet, which manifested attacks of pulsating pain and burning sensations. She had about ten cold and five to seven hot induced paroxysms daily. There were no trophic changes or edema of th...

Chilling injury (CI) symptoms in avocado (Persea americana Mill.) fruit, expressed as mesocarp discoloration, were found to be associated with embryo growth and ethylene production during cold storage. In cvs Ettinger and Arad most mesocarp discoloration was located close to the base of the seed and was induced by ethylene treatment in seeded avocado fruit. However, ethylene did not increase me...

A number of cases of goiter have been reported from Ban Mae Toen (BMT) northwestern Thailand, therefore we carried out this study to evaluate the prevalence and severity of goiter in BMT. We suspected fluoride toxicity as a factor in this phenomenon, therefore we used a WHO model using photographs to carry out a non-medical survey for teeth discoloration and limb deformity at the same time as t...

IMPORTANCE Many drugs have been reported to induce skin and/or mucous membrane discoloration. Ezogabine (retigabine) was recently approved as an add-on drug for the treatment of partial seizures in adults with epilepsy. Mucocutaneous discoloration induced by antiepileptic drugs in general and ezogabine in particular has not been previously reported. OBSERVATIONS Two patients who had received ...

The effect of fluence level on the discoloration of marble surfaces after the removal of the encrustation by 355 nm laser pulses is comparatively studied. Considering the thermochemical reaction possibly occurring in the encrustation during laser irradiation, the mechanism responsible for the discoloration of the cleaned marble surface is analyzed. The reduction of iron oxides by graphite plays...

fluoride-containing solutien. Commercially pure titanium (CP-Ti) and six titanium-based alloys were used: Ti-O.15Pd, Ti6Al-4V, Ti-7Nb-6Al, Ti-55Ni, Ti-10Cu, and Ti-20Cr. Two test solutions were prepared fbr immersion of polished titanium and titanium alloys: one consisting of O,2% NaF + O,9% NaCl (pH 3.8 with lactic acid) and the other of O.1 mol/1 H202 + O.9% NaCl (pH 5.5). Following immersion...

Discoloration-resistant calcium aluminosilicate cement has been formulated to overcome the timely problem of tooth discoloration reported in the clinical application of bismuth oxide-containing hydraulic cements. The present study examined the effects of this experimental cement (Quick-Set2) on the viability and proliferation of human dental pulp stem cells (hDPSCs) by comparing the cellular re...

BACKGROUND Mongolian spots are benign skin markings at birth which fade and disappear as the child grows. Often persistent extensive Mongolian spots are associated with inborn error of metabolism. We report thirteen people of the single family manifested with extensive Mongolian spots showing autosomal dominant inheritance. CASE PRESENTATION A one day old female child, product of second degre...
