Wiskott-Aldrich syndrome is an X-linked combined immunodeficiency disorder characterized by severely decreased number of platelets which are small in size, eczema resembling atopic dermatitis and recurrent infection. The serum of the patient contains elevated concentrations of IgA and IgE, whereas the IgG level is usually normal and IgM level is decreased. The patients also shows skin test anergy and progressive T-lymphocytopenia. Bleedings and recurrent infections are the main causes of death and the patients usually die before age 10. Bone marrow transplantation is accepted to be the only radical therapy. We experienced a case compatible with Wiskott-Aldrich syndrome in a 5 year old male child who accompanied above clinical manifestations and laboratory findings.

Purpose: Radiation-induced oral mucositis limits delivery of high-dose radiation to targeted cancers. Therefore, it is necessary to develop a treatment strategy to alleviate radiation-induced oral mucositis during radiation therapy. We previously reported that inhibiting reactive oxygen species (ROS) generation suppresses autophagy. Irradiation induces autophagy, suggesting that antioxidant treatment may be used to inhibit radiation-induced oral mucositis. Materials and Methods: We determined whether treatment with N-acetyl cysteine (NAC) could attenuate radiation-induced buccal mucosa damage in vitro and in vivo. The protective effects of NAC against oral mucositis were confirmed by transmission electron microscopy and immunocytochemistry. mRNA and protein levels of DNA damage and autophagy-related genes were measured by quantitative real-time polymerase chain reaction and western blot analysis, respectively. Results: Rats manifesting radiation-induced oral mucositis showed decreased oral intake, loss of body weight, and low survival rate. NAC intake slightly increased oral intake, body weight, and the survival rate without statistical significance. However, histopathologic characteristics were markedly restored in NAC-treated irradiated rats. LC3B staining of rat buccal mucosa revealed that NAC treatment significantly decreased the number of radiation-induced autophagic cells. Further, NAC inhibited radiation-induced ROS generation and autophagy signaling. In vitro, NAC treatment significantly reduced the expression of NRF2, LC3B, p62, and Beclin-1 in keratinocytes compared with that after radiation treatment. Conclusion NAC treatment significantly inhibited radiation-induced autophagy in keratinocytes and rat buccal mucosa and may be a potentially safe and effective option for the prevention of radiation-induced buccal mucosa damage.

Bladder urothelial carcinoma typically occurs in individuals in their sixties or seventies: it rarely occurs in persons <20 years old. Moreover, in young patients, bladder urothelial carcinoma lesions are reported to be solitary and nonmuscle invasive, with low malignant potential. However, 13% of lesions in this age group are reported to be noninvasive high-grade papillary urothelial carcinoma but these are extremely rare in children <15 years. There is no specific consensus regarding treatment of bladder urothelial carcinoma in children and adolescent. In particular, method has been suggested for follow-up of high-grade bladder urothelial carcinoma. Therefore we report our experience of one case the, discuss surveillance methods, and provide a brief review of the literature.

An experiment was planned to observe the histopathological alteration with administration of the Rheomacrodex and blood pressure changes in induced cerebral infarct after occlusion. Eighty well developed cats, weighing 2.3 to 3.5kg, were used in this experiment. The right MCA was exposed through temporal approach and the proximal part of the MCA was occluded with a silver clip. The animals were divided into 4 groups: The control group was comprised of 20 cats with occlusion of the right MCA alone, Rheomacrodex-treated group was comprised of 20 cats after occlusion of right MCA, induced hypotension and hypertension groups consisted in each 20 cats following occlusion of the MCA. The animals were sacrificed at intervals of 3 hours, 6 hours, 24 hours, 1 week and 2 weeks respectively after occlusion of the MCA. The animals were studied for clinical deficits and histopathological changes of the cerebral infarct according to the time courses. The results obtained were as follows: 1) In the control group, severe contralateral hemiplegia was developed in the early stage following the MCA occlusion, however the neurological deficits were progressively improved to the state of abnormal walking in 24 hours to 2 weeks. The hemorrhagic infarct was involving the basal ganglia, internal capsule and extending to the cortex with mild brain edema in the early stage and the area of the infarct was gradually enlarged from 6 hours to 24 hours following the MCA occlusion. Although the brain edema of surrounding area of the lesion was remained unchanged, the size and distribution of the infarct were decreased in one week to 2 weeks. Extensive ischemic neuronal damage was observed in the control group. 2) In the Rheomacrodex-treated group, mild to moderate neurological deficit was developed in the early stage after MCA occlusion and the deficit was less severe than control group. The clinical deficit was improving in the time course and one case had shown completely normal activity in 2 weeks. The distribution of the infarct was well defined and it was smaller than control group. The infarct mainly involved the basal ganglia and internal capsule. The area of the infarct was gradually enlarged from 6 hours to one week after MCA occlusion, then the extent of the infarct was decreased in 2 weeks. The ischemic neuronal change in this group was less severe than control group. 3) In the induced hypotension group, the early neurological deficit was worse than that of the control group and severe hemiplegia was developed in one week. There was minimal improvement of the neurological deficit in 2 weeks. The area of the infarct was ill-defined and hemorrhagic extending a large portion of the brain with severe brain edema. The infart was involving the basal ganglia, internal capsule, claustrum and the cortex from 3 hours to 24 hours after the occlusion and the area of the infarct was not changed during the observation. Severe ischemic nerve cell change or resolution of the cells was oserved in this group. 4) In the induced hypertension group, the neurological deficit was mild and it was better than that of the control group. The distribution of the infarct was well localized and minimum in extent. The extent of the infarct was not changed during the observation. There was no observable gross brain edema and the ischemic nerve cell changes were not severe.

The average interval from first operation to recurrence is about 4 years and the reported shortest interval of malignant meningioma is about 6 months. The authors reported a case of rapidly regrowing benign meningioma, located on the outer 1/3 of the right sphenoid wing. The patient was free of recurrence only at 4 months after the first surgery in spite of macroscopic complete removal of the tumor. Factors associated with recurrence of meningioma are also discussed.

We have experienced 19 patients of the cerebral arteriovenous malformation with subarachnoid hemorrhage, who were admitted to the Presbyterian Hospital, Daegu from January 1966 to July 1968, and to the Catholic Medical Center, Seoul from August 1968 to August 1971. All of the patients, who have the cerebral arteriovenous malformation, were proved by cerebral angiography. Since the site of lesions were considered to have close relation to the neurologic deficit and the result of surgery, various analysis of the clinical manifestations and the cerebral angiographic findings were attempted. Of the 19 patients, surgery was performed on 12 patients and its results were analyzed correlating to various types of surgical procedure. Following are the results. 1. From January 1966 to August 1971, there were 100 cases of cerebral vascular anomalies which were proved by cerebral angiography. Among the 100 cases, there were 71 intracranial aneurysms, 19 cerebral arteriovenous malformations, one cavernous angioma, 2 telangiectasis, 5 cerebral rete mirabile, and s Sturge Weber-Dimitris disease. The ratio of arteriovenous malformatons to aneurysms was 1: 3.7. 2. Age distribution of the bleeding arteriovenous malformations was ranged from 8 to 54, and 42 per cent of them were in the third decade. 73 percent of the group had bleeding from the cerebral arteriovenous malformation before the age of 40. The ratio of male to female was 1.9:1. 3. The parietal region was most commonly involved by the malformations. There were 8 parietal lesion, 4 temoroparietal lesions, one temporal lesion, one occipital lesion, and one tela chorioidea lesion. Simultaneous involvement of the both hemispheres occurred in one case. In lesions involving the cerebral hemisphere, there was a predominance of the left side. 4. In the past history, convulsive seizure was recorded in two cases and recurrent hemorrhages were reported in two. One patient was recorded to have suffered fourth hemorrhage and the other have sufferd third hemorrhge. 5. Meningeal irritation signs were most frequently observed in bleeding arteriovenous malformations. The incidence of weakness of extremities was higher in lesions involving the parietal area. Unconsciousness was occurred in 6 patients at the onset of symptom, of which transient loss of consciousness was seen in 3 patients. Transient hypertension at the onset was observed in two patients. 6. The feeding arteries of the malformations were most frequently seen from the middle cerebral artery and the draining veins from the malformations were into the superior sagittal sinus and internal cerebral vein in many cases. It was evident that the carotid artery of the sites of arteriovenous malformations was markedly dilated in 5 patients. 7. Ligation of the vessels feeding the arteriovenous malformations was carried out in 8 patients. One patient had neurologic deficit after the operation. Evacuation of intracerebral hematoma, resection of the anomaly or carotid ligation were carried out in 4 patients. Of the 12 patients who underwent various types of surgery, there was one death after evacuation of a large intracereral hematoma. 8. In our opinion, the ligation of feeding artery a choice of procedure to reduce the incidence of rebleeding, if the resection of the lesion was considered to have operative risk by the location of malformations.
