The highest frequency of penile cancer occurs in Asia, Africa, and Latin America, and there have been a few reports concerning the association of penile cancer with human papillomavirus (HPV) infection in these areas. The objective of this study was to determine the relation between penile cancer and the prevalence of HPV genotypes in northern Thailand.(More)
We examined pathologically a bamboo nodule of the vocal fold by means of immunohistochemical studies and scanning electron microscopic examination. A 38-year-old female showed a high index of antinuclear antibodies without any systemic symptoms but had complained of progressive voice disorder for 9 months. She had used her voice excessively in her(More)
We described three unrelated children with cryptic 9q34.3 rearrangements and similar clinical manifestations: two with 9q34.3 terminal deletions and the other with an unbalanced translocation involving 9q34.3-qter monosomy and 6p25-pter trisomy. Common features among the three we studied and the other six patients with 9q34.3 deletions in the literature(More)
Small intestinal resection rats are used widely as a malabsorption model, but the immunological changes are unclear. We examined the changes in systemic and mucosal immune status after a small intestinal resection in rats with a controlled nutritional status. Rats had 60% of their small intestine removed. At 5 days after the surgery, spleen cells and(More)
This study estimated case fatality rates in Hong Kong, Singapore and Beijing using the number of new admissions, deaths and discharges by cure. To determine the relationships between the hazard for death and that for cure, a cure--death hazard plot was developed. The daily ratios of the two hazards determine the ultimate case fatality rate. The case(More)
Effects of two clinically used liquid diets on toxicity and antitumor activity of methotrexate (MTX) were investigated in Sprague-Dawley (SD) rats and tumor-bearing mice, respectively. Diets tested were commercially available formulas enriched either with soybean and omega-3 fatty acids or with casein. The soybean-containing diet offered significant(More)
QT prolongation and torsades de pointes have been documented in patients administered cisapride and its blocking of potassium channels in myocytes has been suggested as the mechanism. An interaction with cytochrome P450 CYP3A4 inhibitor drugs like macrolide and azole antifungals is also thought to be a possible mechanism. Since mosapride has characteristics(More)
Bilateral vocal fold abductor paralysis was seen in a patient with Creutzfeldt-Jacob disease. After tracheotomy, the patient showed disappearance of reduced oxygen saturation with high-pitched inspiratory stridor and pulling phenomenon of the supraclavicular region and larynx. Electromyographic examinations of the intrinsic laryngeal muscles, including the(More)
SUMMARY This study identified that physiologically the superior pharyngeal constrictor muscle at the level of the base of the tongue contributes to retrusive movement of the tongue with constriction of the mid-pharyngeal cavity and possesses unique properties in terms of motor speech control along with the genioglossus muscle. From a kinematic study(More)
