1.Xeroderma Pigmentosum: The Treatment of Associated Skin Cancer.
Korean Journal of Dermatology 1972;10(2):99-105
Xeroderma pigmentosum is characterized by sunlight sensitivit.y, autosomal recessive inheritance, and multiple cutaneous malignancies, usually basal and squamous cell carcinomas. In this work the effects of bleomycin and topical 5-fluorouracil on basal and squamous cell careinomas appearing in the patient of xeroderma pigmentosum were studied and followed up for two years. The material was a 50 year old female patient of xeroderma pigmentosum associated with basal and squamous cell carrinomas occuring in the exposed area, and its mixed tumor in the nose for thirty years. Duringfirst admission blecmycin was given intravenously in a dosage of 15 mg every other day or twice a week for basal cell carcinomas in the exposed area and mixed tumor in the nose. The total amount of bleomycin given was 315 mg. A year later another squamous cell carcinomas developed on the exposed area. She was treated with topical application of 5% 5-fluorouracil cream daily for 40 days during second admission. The results obtained are summarized as follows: l. The effect of bleomycin is more effective in the squamous cell carcinoma than in the basal cell carcinoma which recurred after 2 years. 2. Topical therapy of 5% 5-fluorouracil cream appeared almost complete effectiveness to the squamous cell carcinoma.

Balancing the rates of cell proliferation and cell death is important in maintaining normal tissue homeostasis. The relationship among apoptosis, cell proliferation and factors influencing apoptosis according to the histologic types in chemically induced mammary tumorigenesis appears important in understanding the pathogenesis of breast carcinoma. In this study, we investigated alterations in the kinetics of cell proliferation and apoptosis during rat mammary tumorigenesis induced by 7, 12-dimethylbenzanthracene (DMBA) and we related these changes to the expressions of bcl-2, p53, and TGF-beta. Seven-week-old female Sprague-Dawley rats were divided into an experimental group (20 mg/ml DMBA by oral intubation) and a control group. The results were as follows. 1. In the experimental group, breast tumors occurred in twenty two of fifty nine rats(37.3%, 22/59), and the total number of tumors was 100 (4.5 2.0/rat). The histological classification was infiltrating ductal carcinomas (n=5), ductal carcinomas with focal invasion (n=10), intraductal carcinomas (n=36), adenomas accompanied with intraductal proliferation (n=35), intraductal proliferation (n=9), and adenomas (n=5); 2. The differentiation of terminal end bud into alveolar bud (AB) in the experimental group was significantly lower than that of the control group (p<0.05); 3. BrdU labeled tumor cells were mainly located at the peripheral portion of tumor cell nests. BrdU labeling indices were highest in ductal carcinomas, less pronounced in intraductal proliferation, and lowest in adenomas, whereas apoptosis levels were highest in adenomas, less pronounced in intraductal proliferation, and lowest in ductal carcinomas (p<0.05); 4. p53 protein was not expressed in any breast tumors. Although the expression of bcl-2 protein was highest in infiltrating and focal infiltrative ductal carcinomas (58.3%), compared with adenomas, intraductal proliferation, and intraductal carcinomas (p<0.05), the extent of its expression was less than 1% of all tumor cells; 5. TGF-beta was mainly expressed in the central portion of tumor cell nests rather than in peripheral portion, and TGF-beta immunoreactive tumor cells displayed good differentiation and did not reveal BrdU immunoreactivity. TGF-beta labeling index of infiltrating and focal infiltrative ductal carcinomas was significantly higher than that of intraductal carcinomas, intraductal proliferation, and adenomas (p<0.05). Based on these results, it is thought that high cell proliferation and the suppression of apoptosis are closely associated with DMBA-induced rat mammary carcinogenesis. However, the suppression of apoptosis is not related to p53 mutation, bcl-2, and TGF-beta. TGF-beta seems to be reversely related to tumor cell proliferation but closely associated with the progression of the tumor, especially an invasion of breast carcinomas.

Heat shock protein 70 (HSP70) is a chaperone that binds to mutant p53 and consequently can regulate its accumulation or localization. Its expression is upregulated in tumor cells. We studied 44 adenomas and 29 carcinomas of colorectum to evaluate the expression of HSP70, and to assess the correlation among p53 protein and other clinical prognostic parameters. HSP70 expression was scored according to staining intensity and extent. p53 protein expression was 45.5%(20/44) in adenomas and 79.3%(23/29) in carcinomas(P<0.01). p53 protein expression of carcinomas was 57.1%(4/7) in diploidy tumors, 100.0%(8/8) in aneuploidy tumors(P=0.07), 100.0%(8/8) in well-differentiated tumors, and 50.0%(2/4) in poorly differentiated tumors(P= 0.09). HSP70 expression mainly revealed a fine granular cytoplasmic staining pattern in tumor cells. HSP70 was focally detected in some lymphocyte, ganglion cell and normal mucosa. HSP70 expression was 46.3%(19/41) in adenomas and 93.1%(27/29) in carcinomas. HSP70 score was 0.9+/-1.3 in adenomas(n=41) and 5.5+/-3.5 in carcinomas(n=29)(P<0.0005). Its score was 1.7+/-1.6 in p53 positive adenomas and 0.3+/-0.6 in p53 negative adenomas(P<0.005), and its expression rate was higher in p53 positive carcinomas than p53 negative carcinomas (P>0.05). There was no significant correlation among HSP70, tumor size, Dukes'stage, nodal metastasis, depth of tumor invasion, DNA ploidy and tumor differentiation. In conclusion, HSP70 and p53 protein appear to be correlated to each other, and that HSP70 and p53 protein may play a certain role in the progression of colorectal tumor. Further studies are needed for determining their prognostic factors in colorectal carcinoma.

A case of eavernous hemangiomatosis involving alI tendon sheath of flexors and median nerve of the right forearm is reported. This case was a 22 year old Korean male who complained of painful swelling of the flexor side of right wrist region, limited motion of wrist joint, loss of pinching and opposition with tingling sensation on the admission. Roentgenographic examination revealed fusiform swelling of the soft tissues in flexor aspect of the right wrist region, with phlebolith, 3mm. in diameter. The tumor mass looked like strawberry in shape, and was scattered into all tendon sheath of flexors of the forearm, median nerve, the distal half of pronator quadrtus and other surrounding soft tissues. The specimen was confirmed as cavernous hemangioma in microscopic examination. The right long arm splint was applied for 3 weeks, and then the patient was treated with physical therapy for 4 months. Pinching, opposition, and motion of the right wrist joint recovered almost completly, and no evidence of the recurrence of hemangiomatosis was seen until 8 months after surgery.

6.The Effect of Chemical Myectomy using Doxorubicin Delivered by Osmotic Pump on Eyelid Skin Necrosis.
Journal of the Korean Ophthalmological Society 2001;42(8):1210-1219
PURPOSE: Direct injection of doxorubicin into the eyelids results in permanent loss of muscle fiber and it is considered an attractive nonsurgical method in essential blepharospasm therapy. However, necrosis of skin overlying orbicularis oculi muscle is the most serious side effect of this therapy. The purpose of this study is to determine the effect of doxorubicin delivered by osmotic pump which release doxorubicin slowly, and to evaluate the degree of overlying skin injury following chemical myectomy. METHODS: Thirty three rabbits were assigned to three groups according to the doxorubicin concentration. The first group received direct injections of 0.5 mg doxorubicin diluted in 0.1 ml of saline in the right lower eyelid. and osmotic pump was inserted into the left lower eyelid which contained 0.5 mg doxorubicin in 0.1 ml of saline. The second group received 1 mg doxorubicin and the third group received 2 mg doxorubicin. Eight weeks after injection, the eyelids were assessed for the degree of muscle fiber loss microscopically. For the evaluation of functional change of muscle, an EMG study was carried out. RESULTS: Skin necrosis developed in all rabbits except for one which received injection of 0.5 mg doxorubicin. Skin necrosis appeared earlier in the direct injection group. The duration of skin necrosis was shortened at lower concentrations(0.5 mg, 1.0 mg) with a pump delivery(P<0.05). But there was no statistical differences in the 2.0 mg concentration. The size of necrosis was much smaller in rabbits using pump delivery than those of direct injection group in high doxorubicn concentrations(1.0 mg, 2.0 mg)(P<0.05). The total size of muscle fiber was decreased after a doxorubicin injection. There was no statistical difference between the direct injection group and the pump group(P<0.05). The similar effect on the muscle was noted regardless of the slow release of the doxorubicin into the muscle. Light microscopic study demonstrated destructive change of muscle and it was replaced by connective tissues. Electron microscopic study showed destruction of micro-architecture of muscle fibers. Functionally, in EMG study, there was no motor activity in the injection area. But some motor unit potentials appeared in the periphery of skin necrosis site. CONCLUSIONS: These results suggest that the osmotic pump may be used as an effective adjuvant in preventing skin necrosis in blepharospasm treatment.

OBJECTIVES: Depression, sleep complaints and cognitive impairments are commonly observed in the elderly. Elderly subjects with depressive symptoms have been found to show both poor cognitive performances and sleep disturbances. However, the relationship between sleep complaints and cognitive dysfunction in elderly depression is not clear. The aim of this study is to identify the association between sleep disturbances and cognitive decline in late-life depression. METHODS: A total of 282 elderly people who underwent nocturnal polysomnography in a sleep laboratory were enrolled in the study. The Korean version of the Neuropsychological Assessment Battery developed by the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) was applied to evaluate cognitive function. Depressive symptoms were assessed with the geriatric depression scale (GDS) and subjective sleep quality was measured using the Pittsburg sleep quality index (PSQI). RESULTS: The control group (GDS< or =9) when compared with mild (10< or =GDS< or =16) and severe (17< or =GDS) depression groups, had significantly different scores in the Trail making test part B (TMT-B), Benton visual retention test part A (BVRT-A), and Stroop color and word test (SCWT)(all tests p<0.05). The PSQI score, REM sleep duration, apnea-hypopnea index and oxygen desaturation index were significantly different across the three groups (all indices, p<0.05). A stepwise multiple regression model showed that educational level, age and GDS score were predictive for both TMT-B time (adjusted R2=35.6%, p<0.001) and BVRT-A score (adjusted R2=28.3%, p<0.001). SCWT score was predicted by educational level, age, apnea-hypopnea index (AHI) and GDS score (adjusted R2=20.6%, p<0.001). Poor sleep quality and sleep structure alterations observed in depression did not have any significant effects on cognitive deterioration. CONCLUSION: Older adults with depressive symptoms showed mild sleep alterations and poor cognitive performances. However, we found no association between sleep disturbances (except sleep apnea) and cognitive difficulties in elderly subjects with depressive symptoms. It is possible that the impact of sleep disruptions on cognitive abilities was hindered by the confounding effect of age, education and depressive symptoms.

OBJECTIVES: This study aimed to examine the point prevalence of anxiety, depression and the associated risk factors in hospitalized patients with cancer. METHODS: A total of 114 patients with cancer who admitted to the Cancer Center in St. Mary's Hospital were enrolled for a day. The patients were asked to complete Hospital Anxiety and Depression Scale(HADS). Sociodemographic and cancer related clinical variables were also evaluated. RESULTS: The point prevalence of anxiety and depression was 10.5% and 34.2%, respectively, as assessed with HADS. Logistic regression models revealed that distant metastasis was significantly associated with anxiety in patients with cancer and previous chemotherapy and Low socioeconomic status were significantly associated with depression. CONCLUSIONS: Our results indicate that more than one third of patients with cancer suffer from either anxiety or depression. In addition, previous chemotherapy as well as low socioeconomic status and distant metastasis were associated risk factors of anxiety and depression, respectively. These findings suggest the need for screening and systematized psychosocial intervention for psychological distress in hospitalized patients with cancer.
