Studies on taeniasis in Taiwan. V. Field trial on evaluation of therapeutic efficacy of mebendazole and praziquantel against taeniasis.

Taeniasis is a major public health problem among the aboriginal populations on Taiwan, and is highly prevalent and wide spread in the mountain areas of 10 Counties. Over 27,000 cases of tapeworm infection are estimated influencing the health and economy in the endemic areas. A treatment of taeniasis with mebendazole and praziquantel followed by a re-treatment with atabrine has been done in the field trial, and confirmed that praziquantel is highly effective agent against tapeworm infection, but mebendazole is not. Based upon experiments reported here praziquantel in a single dose of 150 mg, and 450 mg are highly effective against taeniasis and hymenolepiasis respectively.

[Survey of helminthic infections and treatment of Taenia species infection among the aborigines in Chien-Shih District, Hsin-Chu County, northern Taiwan].

Six hundred and sixteen out of 770 (80%) aborigines examined were found to be infected with intestinal helminthes. A total of 7 species of parasites were detected with the formalin-ether concentration technique. The infection rate of Ascaris lumbricoides was 77.1%, Trichuris trichiura 28.8%, Taenia sp. 18.4%, Enterobius vermicularis 1.6%, and there was one case each of hookworm, Hymenolepis nana and H. diminuta infections. Infection rate was slightly higher among females (81.3%) than males (78.9%). It was also higher in Yu-Feng (86.9%) than Shiu-Luan villages (75.5%). The incidence of helminthic parasites was found in all ages. 11-20 age-group was the highest (84.4%), followed by 1-10 (81.5%), 51 and more (80.6%), 41-50 (77%), 31-40 (76%), and 21-30 (72%). In general, the rate seems to be higher among the young and old. But, the rate of Taenia sp. was increased with the increase in age. Taenia sp. was found to be of considerable high prevalence. However, only 7 out of the 252 (2.7%) junior high school students were found infected in contrast to the 18.4% found in the villages. After atabrine treatment, 108 adult worms, 83 with and 25 without scolices were obtained from 54 of 72 treated cases. The number of expelled worms varied from 1 to 8, with an average of 2 worms per infected person. 29 (53.7%) aborigines expelled only one worm, and 25 (46.3%) cases expelled more than one worms.

Epidemiology of Enterobius vermicularis infection among orphans in orphanages in Taipei City.

Children of eight orphanages at the different districts in Taipei were examined with scotch adhesive tape method and flotation of saturated NaCl solution from Sept. 1973 to Jan. 1974. The results are summarized as following: General incidence of Enterobius verminularis was 74.40% in 461 cases examined, male 76.45% (224/293), female 70.83% (119/168). There was no significant statistical difference between the male and female. Incidence of Enterobius among the orphanages was 83.33% (25/30) in Po-Ai, Fu-Ann 82.61% (38/46), Ta-Tung 82.43% (61/74), Hau-Sen 77.25% (34/44), Chung-I 75.00% (51/68), Jen-Ai 72.97% (23/37), Ti-Hwei 72.50% (29/40) and Sen-Tao 63.93% (78/122). There were no significant statistical differences among the orphanages except the differences between Sen-Tao and Ta-Tung; Sen-Tao and Fu-Ann, Sen-Tao and Po-Ai. Incidence of Enterobius according to age-groups: The highest rate was 79.34% (242/305) in primary school group followed by 70.00% (21/30) in kindergarten group, 64.40% (73/114) in Junior high school and the lowest was 63.64% (7/11) in nursery group. There was a significant statistical difference between primary school group and junior school group. (Table 3) The larger the space for the children's free activity was the lower the incidence of Enterobius, and the smaller space resulted in the higher incidence. The distribution of Enterobius ova in the different body parts of the 461 orphans was 80.91% (373/461); The highest 74.40% (343/461) at perianal area and the lowest 11.93% (55/461) at ears. The incidence of Enterobius on the various objects in the orphanages was found as the following: 85.71% (6/7) on bed pans, 83.67% (333/398) on linens, 78.46% (51/65) on w. c. appartus, 77.39% (89/115) on specimens of dust, 13.33% (1/15) on stairrails 8.04% (32/39) on bedposts, 7.33% (11/150) on closets, 4.24% (5/118) on desks and 3.64% (2/55) on toys.

Treatment of Taenia saginata infection with mixture of areca nuts and pumpkin seeds.

In January and February 1974, 32 adults (20 males and 12 females) and a 13-year-old girl with taeniasis saginata were treated with the mixture of boiled areca nuts and pumpkin seeds at Mastoban, Jen-ai District, Nantou County, Taiwan. A total of 48 worms including 42 scolices were recovered from 29 cases. Side-effects were observed in 4 cases including 3 with complaints of dizziness, tinnitus, nausea and vomiting, and one with coma and abdominal pain. Mixtures of 75-150 g areca nuts and 50-100 g pumpkin seeds were judged effective and safe.

Oral rehabilitation of a patient with scleroderma associated with systematic lupus erythematosus: a case report.

This case report presents a patient who had a limited oral opening due to systematic lupus erythematosus (SLE) and describes how oral rehabilitation was achieved with a removable partial denture. Various techniques for the delivery of oral health care have been reported for patients who have limited mouth openings as a result of SLE and scleroderma. After a review of the literature, a new approach was required for this patient with SLE who had a very limited mouth opening. The retention for the removable partial denture (RPD) used the undercut in the abutment teeth and a magnet-retained sectional RPD. A set of tweezers was modified to help with the insertion and removal of the sectional RPD by the patient. This paper reports a new clinical and laboratory technique of fabricating a sectional RPD using magnets and customized tweezers for this patient.
