Hepatic resection in the treatment of hepatocellular carcinoma: report of 60 cases.

During the last 3 years and 9 months, hepatic resections were carried out on 60 patients with hepatocellular carcinoma (HCC). The resections were radical in 44 and palliative in 16 cases. Simultaneous operations were performed for oesophageal varices in 11 (9 prophylactic and 2 therapeutic) and for cholelithiasis in 9 patients. Fifty-nine patients had underlying hepatic disease; 52 had cirrhosis and 7 chronic hepatitis. Operative mortality rate within 1 month was 10 per cent and overall hospital mortality rate was 16.7 per cent. Excluding operative and hospital deaths, 76.8 per cent of patients who had radical excision and 18.8 per cent with palliative resections are alive. The result indicates that HCCs are frequently resectable even in the presence of liver cirrhosis provided that they are discovered at a relatively early stage.

A simple operative procedure for the treatment of Stahl's ear.

Stahl's ear is a rather rare congenital deformity and operative procedures for its correction have seldom been reported. We recently devised a simple method of surgical treatment, which is briefly described as follows: incisions are made into the third crus cartilage to facilitate the formation of a helical fold, and the cartilage is sutured by means of a mattress suture. This method makes it possible to produce a natural helix, though it fails to eliminate the third crus.

Ability of enzymes to remove Candida.

Infection by C. albicans is a significant cause of denture stomatitis. Therefore, the results of this study, which demonstrated that yeast lytic enzymes and proteolytic enzymes removed C. albicans from acrylic resin surfaces, suggest that these compounds are potentially useful denture cleansers.

A decade of progress for the adhesive fixed partial denture.

The history of the development of adhesive fixed partial dentures was reviewed and present clinical problems discussed. Longitudinal studies are not available because adhesive prostheses with 4-META adhesive resin were introduced only a few years ago. However, scientific advances will make placement of resin-bonded metal prostheses a more stable, standard technique in fixed prosthodontics.

Ameloblastoma with hypoproteinemia due to protein leakage.

One peculiar case of giant ameloblastoma of the mandible is reported in this paper. This case is characterized by 2 interesting points: large tumor size of an infant's head, hypoproteinemia caused by leakage of serum protein, especially albumin, via fistula formed in the gum and edema of the body. Problems accompanying hypoproteinemia are discussed.

Increase of mast cells in the alopecia lesion of mice.

A histological investigation was made of the quantitative behavior of mast cells in bald areas on mice and in human alopecia areata. C57BL,W/Wv and +/+ mice with alopecia lesions were examined. In C57BL mice and +/+ mice, the number of dermal mast cells (per square mm) in the bald areas was greater than that in controls. The mean number of mast cells was slightly higher in human alopecia areata than in the controls. Since W/Wv mice lacking mast cells developed alopecia lesions, it seems that mast cells are not necessary for the onset of alopecia areata but could play some part in regrowth.
