Paragonimiasis is widely distributed in Far East and Southeast Asia, particularly in Korea. The central nervous system is the most frequent location for paragonimiasis outside the lungs. We analized the computed tomographic findgins of 17 cases which were diagnosed pathologically and clinically as cerebral paragonimials. The results were as follows : 1. The ratio of mate to female was 10 : 7 and about 88% of cases were under the age of 40 years. 2. The common locations of cerebral paragonimiasis were the occipital (12 cases) and temporal (11 cases) lobes. 3. Precontrast CT findings of cerebral paragonimiasis were low density with calcifications in 6 cases, low and isodensities in 4 cases, mixed densities in 3 cases, only low density in 2 cases and only calcifications in 2 cases. Hydrocephalus (7 cases), mass effect (6 cases), atrophic change (6 cases) and cyst formation (3 cases) were associated. 4. The shape of calcifications in CT scan were soap-bubble or ring in 6 cases, nodular or oval in 6 cases, stippled in 4 cases and amorphous conglomerated in 2 cases. 5. The contrast-enhanced 8 cases were 5 ring or rim like, 2 nodular and 1 irregular enhancements, while 9 cases were not enhanced.

Authors analyzed 72 cases of abdominal computed tomography of Korean adults who didn't have any medical reasons to believe the spleen was abnormal. The following criteria were measured with multiple transverse scanning of the entire length of spleen (height, breadth, thickness) & relationship with fixed midline structure, the spine (the shortest distance from midline to medial edge of spleen, the longest distance from anterior margin of vertebral body to anterior tip of spleen). The results were as follows : 1. The average size in adult was 8.0$\pm$1.5cm in height, 8.6$\pm$1.2cm in breadth and 3.4$\pm$ 0.6cm in thickness ; in adult female, 7.8$\pm$1.1cm, 8.4$\pm$1.0cm and 3.4$\pm$0.6cm, respectively ; total average, 7.9$\pm$1.3cm, 8.5$\pm$1.1cm and 3.4$\pm$0.6cm, respectively. No remarkable difference was noted between both sexes and age group. 2. The shortest distance from midline to medial edge of spleen was 4.1$\pm$1.1cm in male, 3.6$\pm$1.0cm in female and total average of 3.9$\pm$1.1cm. There was remarkable difference between both sexes (p <0.05) but not between age groups. 3. The longest distance from anterior margin of vertebral body to anterior edge of spleen was 2.3$\pm$1.7cm in male, 2.0$\pm$1.4cm in female and total average of 2.2$\pm$1.6cm. No remarked difference was seen between both sexes and age groups.

We experienced a case of the papillary thyroid carcinoma seen as a huge solid lateral neck mass. The mass grew very slowly over the period of 30years up to 10cm in diameter while relatively well sparing the surrounding tissues. Physical examinations, CT scan, and fine needle aspiration cytology did not reveal any strong suggestions for evidence of malignancy. But it was pathologically diagnosed as metastatic thyroid carcinoma by excisional biopsy. We emphasize that for a large solitary neck mass which persists for several decades, head and neck surgeons should always keep in mind the possibility of metastasis from the malignancy of thyroid gland.

전폐조사로 유발된 마우스의 급성폐손상에 대한 스테로이드의 효과

성낙관(Nak Kwan Sung),신세원(Sei One Shin),권건영(Kun Young Kwon) 대한방사선종양학회 1997 Radiation Oncology Journal Vol.15 No.1

목 적 : 방사선량에 따른 급성폐손상을 병리조직학적으로 분석하고 예방목적으로 투여한 스테로이드의 효과를 확인하여 방사선에 의한 폐손상의 감소방안을 모색하고자 한다. 대상 및 방법 : 생후 30일 정도인 체중 25+2g의 ICR 마우스 120마리를 암수 구별없이 사용하였고, 대조군은 전폐선량이 각각 8Gy와 12Gy인 방사선조사만 시행한 군과 방사선조사와 생리 식염수를 투여한 또다른 군으로 하였으며, 실험군은 방사선조사와 스테로이드를 복강내로 투여한 군으로 하여 방사선량과 스테로이드투여에 따른 급성폐손상의 양상을 광학 현미경 및 투과 전자현미경을 이용하여 병리조직학적으로 분석하였다. 결 과 : 8Gy 대조군에서는 경미한 염증세포의 침윤, I형 폐포상피세포는 세포질이 파괴되거나 폐포강내로 돌출하였으며, 폐포 모세혈관은 경미하게 확장되었고 내피세포의 세포질과 간질은 경한 부종을 보였다. 8Gy 실험군에서는 대조군에서 보였던 폐포상피세포 및 내피 세포의 변화가 정도가 매우 약하였으나 섬유모세포의 증식과 기저판의 파괴정도는 대조군과 비슷하였다. 12Gy 대조군에서는 8Gy 대조군과 비교하여 염증세포의 침윤이 증가되었고 폐포강내에는 파괴된 조직파편이 산재해 있었으며 폐실질의 출혈과 무기폐가 관찰되었다. 12Gy 실험군에서는 대조군에서 보이던 현저한 염증변화가 많이 감소하였으며 폐포벽의 부종과 무기폐는 대조군과 비교하여 많이 감소되었으나 섬유모세포의 증식과 기저판의 왜곡 및 파괴는 차이가 없었다. 결 론 : 방사선조사에 의한 급성폐손상은 전폐조사량이 8Gy에서 12Gy로 증가함에 따라 염증세포의 침윤, 폐포상피세포의 손상, 모세혈관 내피세포의 손상, 간질의 부종정도가 증가하였으며, 방사선조사후 스테로이드를 2주일에서 4주일간 투여한 결과 이들 소견이 많이 감소하였으나 섬유모세포의 증식정도와 기저판의 변화는 조사된 방사선량이나 스테로이드투여여부와 무관하였다. Purpose : To investigate ultrastructural changes of the mouse lung induced by whole lung gamma irradiation and to evaluate the effect of prophylactic administration of steroid against acute lung injury. Materials and Methods : One hundred and twenty ICR mice were used and whole lung was irradiated with telecoba lt machine . Whole lung doses were 8 and 12Gy, and 10mg of methyl prednisolone was administrated intrape ritoneally for two and four weeks . At the end of the obse rvation period, mice were sacrificed by cervical dis location. The lungs were removed and fixed inflated. Histopathological examination of acute radiation injuries we reperformed by light microscopic and transmiss ion electron microscopic examination. Re s ults : Control group with 8Gy is cha racte rized by damage to the type I pneumocyte and the endothe lial cell of the ca pillary, edema of a lveolar wall and inte rstitium, and fibroblast prolife ration. Control group with 12Gy is characte rized by more severe degree of type I pneumocyte damage and more prominant inflammatory cell infiltration. Destructed cell debris within the a lveolar space were a lsonoted. After steroid administration, 8Gy experimental groups howed decreased degree of inflammatory reactions but fibroblast prolife ration and basal lamina damages we re uncha nged. Experimental group with 12Gys howed lesser degree of inflammatory reactions similar to changes of 8Gy experime ntal group. Conclusion : These studies suggest that the degree of interstitial edema and inflammatory changes were related to radiation dose but proliferation of the fibroblast and structural changes of basal lamina were not related to radiation dose . Experimental administration of steroid for 2 to 4 weeks after whole lung irradiation suggest that steroid can suppress a lveolar and endothelial damages induced by whole lung irradiation but prolife ration of the fibroblast and structural changes of basal lamina were not related to administration of steroid.

The most common causes of cortical blindness are ischemic stroke, cardiac surgery, and cerebral angiography. Its characteristic clinical manifestations are: (1) bilateral partial or total blindness, (2) intact pupillary light reflexes and no abnormality in extraocular muscle movements, (3) normal ophthalmoscopic finding, (4) optokinetic nystagmus (may or may not be present). The possible mechanism of angiography-related cortical blindness is neurotoxicity of the contrast agents. Transient, symmetric enhancement in bilateral occipital lobes in CT or MRI is observed frequently. EEG is also an important diagnostic method. No specific treatment is known as effective, but several possible methods are suggested. We presented a case of transient cortical blindness after bronchial arteriography.

Reconstruction of soft tissue defects on the lower leg and foot remains a difficult challenge for surgeons. If the defect was large and complicated by bone defects, an excellent result could be obtained with free tissue transfer. In case of no bony problem, no major infection and relatively small defect, a local flap is more convenient and economic than free tissue transfer because of its simple, one-stage and reliable operation. The vascularization of the subcutaneous tissue reveals the predominance of the vascular network in this layer with regard to the dermal or fascial plane. The dermal vascular network at the donor site is sufficient to let the skin survive without its underlying subcutaneous vascular support. Distally based adipofascial flaps, nourished by the lower perforator originating from the major vessel as link pattern were used successfully for reconstruction of the bone and/or tendon exposure of the lower leg and foot in 10 patients. Between February 1992 and December 1995, ten cases underwent this procedure to reconstruct soft tissue defect on the lower leg and foot. The average age of the patients was 50.6 years (range5 - 73 years). Follow-up was from 10 months to 38 months (mean 21months). The average time of the operation was about 2 hours 18 minutes. The length to width ratio of adipofascial flap was 2.4-5:1 (mean 3.4:1). The advantages of this method are easy dissection, short operation, preservation of the major vascular pedicles of the lower limb, skin preservation at the donor site, thus preserve the shape of the limb and minimize donor site scar, and versatility (it is supple and can adapt to every surface, and it can be grafted on the deep or the superficial side). In conlcusion, this technique is an useful and alternative method for reconstruction of soft tissue defects on the lower leg and foot in selected cases.

Purpose: Proximal subclavian artery stenosis is relatively uncommon and usually asymptomatic. It is well known that the retrograde flow through ipsilateral vertebral artery is not related with onset of clinical symptom and not a definite indication of treatment. Method: We reviewed six patients including four patients who underwent percutaneous transluminal angioplasty to correct the difference of blood pressure between arms. Result: Nobody shows marked clinical improvement even though there was definite technical success. Conclusion: It is considered that angioplasty could be done for the treatment in most of subclavian artery stenosis.
