Higher frequencies of anemia, vitamin B12 deficiency, and gastric parietal cell antibody positivity in folic acid-deficient Taiwanese male oral submucous fibrosis patients.

Background/purpose: Oral submucous fibrosis (OSF) is a progressive fibrotic oral mucosal disease associated with betel quid chewing. This study evaluated whether Taiwanese male OSF patients with folic acid (FA) deficiency (the serum FA level ≤6 ng/mL, so-called FA-deficient OSF patients) had high frequencies of blood hemoglobin (Hb) and serum iron and vitamin B12 deficiencies, and serum gastric parietal cell antibody (GPCA) positivity.

Materials And Methods: The blood Hb and serum iron, vitamin B12, FA, and GPCA concentrations in 59 Taiwanese male FA-deficient OSF patients were measured and compared with the corresponding data in 118 age-matched healthy male control subjects.

Higher frequencies of anemia, hematinic deficiencies, and gastric parietal cell antibody positivity in vitamin B12-deficient Taiwanese male oral submucous fibrosis patients.

Abstract Background/purpose: Oral submucous fibrosis (OSF) is a progressive fibrotic oral mucosal disease associated with betel quid chewing. This study evaluated whether Taiwanese male OSF patients with vitamin B12 deficiency (the serum vitamin B12 level ≤ 450 pg/mL, B12-deficient OSF patients) had high frequencies of blood hemoglobin (Hb) and serum iron and folic acid deficiencies, and serum gastric parietal cell antibody (GPCA) positivity.

Materials And Methods: The blood Hb and serum iron, vitamin B12, folic acid, and GPCA concentrations in 66 Taiwanese male B12-deficient OSF patients were measured and compared with the corresponding data in 132 age-matched healthy male control subjects.

Combined evaluation of both WEE1 and phosphorylated cyclin dependent kinase 1 expressions in oral squamous cell carcinomas predicts cancer recurrence and progression.

Background/purpose: WEE1 is a mitotic inhibitor at G2 checkpoint of the cell cycle that negatively regulates cyclin-dependent kinase 1 (CDK1) through inhibitory phosphorylation. This study assessed whether the expressions of both WEE1 and phosphorylated CDK1 in specimens of oral squamous cell carcinoma (OSCC) might predict the OSCC recurrence and progression.

Materials And Methods: This study used immunohistochemistry to examine the expressions of WEE1 and phosphorylated CDK1 proteins in 75 specimens of OSCC and 30 specimens of normal oral mucosa (NOM).

Development of dental education for medical students in Taiwan during the Japanese colonial period.

Background/purpose: During the Japanese colonial period, Taiwan had a medical school education system for cultivating physicians, but did not have a dental school education system for cultivating "real" dentists. In this investigation, we collected and analyzed the historical documents related to dental education to study the development of dental education for medical students in Taiwan during the Japanese colonial period.

Materials And Methods: This study mainly analyzed the changes in the development of dental education for medical students in Taiwan during the Japanese colonial period through the collection and sorting of relevant historical materials.

Anemia, hematinic deficiencies, and hyperhomocysteinemia in male and female burning mouth syndrome patients.

Background/purpose: Our previous study found that 19.8%, 16.2%, 4.

Dental technology of Taiwan during the Japanese colonial period.

Background/purpose: During the Japanese colonial period, the Taipei Hospital had already provided complete dental services with a fixed price per treatment. This study tried to compare the differences in the prices of various dental treatments between the Japanese colonial period and today.

Materials And Methods: This study used the "Dental Treatment Fees in the 27th Annual Report of Taipei Hospital (Taisho 12)" as the study materials to compare the differences in the prices of various dental treatments between the Japanese colonial period and today using the monthly salary of a novice elementary school teacher as an income benchmark.

Higher gastric parietal cell antibody titer significantly increases the frequencies of macrocytosis, serum vitamin B12 deficiency, and hyperhomocysteinemia in patients with burning mouth syndrome.

Background/purpose: Our previous study found 109 gastric parietal cell antibody (GPCA)-positive burning mouth syndrome (BMS) patients (so-called GPCABMS patients in this study) in a group of 884 BMS patients. This study evaluated whether high-titer (GPCA titer ≥ 160) GPCABMS patients had greater frequencies of macrocytosis, anemia, serum iron and vitamin B12 deficiencies, and hyperhomocysteinemia than low-titer (GPCA titer < 160) GPCABMS patients or 442 healthy control subjects.

Materials And Methods: Complete blood count, serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 42 high-titer GPCABMS patients, 67 low-titer GPCABMS patients, and 442 healthy control subjects were measured and compared.

Anemia, hematinic deficiencies, and hyperhomocysteinemia in serum gastric parietal cell antibody-positive burning mouth syndrome patients without serum thyroid autoantibodies.

Background/purpose: Our previous study found that 70 of 884 burning mouth syndrome (BMS) patients have serum gastric parietal cell antibody (GPCA) positivity but without thyroglobulin antibody (TGA) and thyroid microsomal antibody (TMA) (so-called GPCATGA-TMA-BMS patients). This study assessed whether these 70 GPCATGA-TMA-BMS patients had significantly higher frequencies of macrocytosis, anemia, hematinic deficiencies, and hyperhomocysteinemia than 553 GPCA-negative, TGA-negative, and TMA-negative BMS (GPCA-TGA-TMA-BMS) patients or 442 healthy control subjects.

Materials And Methods: Complete blood count, serum iron, vitamin B12, folic acid, homocysteine, GPCA, TGA, and TMA levels in 70 GPCATGA-TMA-BMS patients, 553 GPCA-TGA-TMA-BMS patients, and 442 healthy control subjects were measured and compared.
