Young adult stroke is not rare disease and have diverse causes. We studied 135 young adults aged 15 - 45 years who had been admitted to Severance Hospital with a diagnosis of cerebral infarction from January 1990 to June 1995. The results are as follows. 1. The diverse causes of earshot infarction in young adults have been found in most patients(88.2%). The major causes of cerebral infarction in young adults were atherosclerosis(32.6%) and cardioembolism(32.6%). The causes were significantly different between younger(15 - 30 years old) and older(31 - 45 years old) patients. 2. The major risk factors of atherosclerotic cerebral infarction were hypertension(29 patients), smoking(14 patients), and hyperlipidemia(11 patients). 3. The major causes of cardioembolism were valvular heart disease(21 patients) and prosthetic valve(I0 patients). The mitral valve prolapse was discovered only in one patient. 4. Fourteen patients had non-atherosclerotic vasculopathies. The moyamoya disease was the most common cause of them. 5. The other causes of cerebral infarction were found in 17 patients and the major causes were alcohol intoxication and postoperative thromboembolism. 6. The cerebral infarction occurred mostly in the carotid artery territory(95 patients) and the distribution of the involved vascular territory was not different between younger and older age groups. 7. The clinical outcomes were good in most patients (86, 7%). From the above results, we demonstrated that young adults with cerebral infarction had various causes and showed favorable clinical outcomes. We also found that the causes of cerebral infarction varied between younger and older groups. Our findings suggest that careful and thorough case-by-ease evaluation may be mandatory to clarify the causes of cerebral infarction in young adults.

Journal of the Korean Neurological Association 1999;17(6):891-894
Idiopathic hypertrophic pachymeningitis is a rare inflammatory disease of unknown origin in which the recurrence is frequently observed despite an initial response to steroid therapy. Four patients, two men and two women aged 63 to 67 years, with severe headaches were evaluated by a brain MRI, and two patients were evaluated by follow up MRI receiving azathioprine therapy. All patients were given initial oral prednisolone 60mg or steroid pulse therapy followed by oral prednisolone and azathioprine therapy. Four patients improved with prednisolone but became steroid depen-dent. Azathioprine therapy permitted a reduction of the corticosteroid which may lead to clinical and radiological improvement. At present, high dose corticosteroid therapy is the treatment of choice, followed by immunosuppressive agents, such as azathioprine, if necessary. Further long-term follow-up studies of these patients are needed to clarify the outcome of this rare disease.

OBJECTIVES: Cadmium (Cd), a toxic and non-essential metal, is recognized as a human carcinogen, which has a tendency to accumulate in the human body. The levels of Cd in renal cortex and liver are good indicators as an index of Cd exposure in the general population. In this study, we present an estimation of reference Cd levels in tissue (renal cortex and liver) and total body burden in the general population of Korea. MEDTHODS: Cd and zinc (Zn) were analyzed in renal cortex and liver from 254 autopsies (male : 188 cases, female : 66 cases) aged 0 to 87 years. RESULTS: Geometric mean concentration of Cd was 27.4 and 3.1 ua/g wet weight in renal cortex and liver, respectively. The level of Zn in renal cortex and liver was 35.4 and 42. 6 v/g wet weight, respectively. The result suggests that kidney is the target organ for Cd accumulation. The accumulation of Cd in renal cortex was age-dependent with a biphasic pattern. The level of Cd in renal cortex increased with age up to the fifties, and then leveled off thereafter. Based on the data, the regression model for Cd accumulation in renal cortex by age is predicted by : Log KCd = 0. 2325 + 0. 0553 Age 0. 0005 Age. The highest Cd accumulation in renal cortex of Koreans was estimated at 43. 3 ua/g wet weight at 50. 8 years old. In addition, the total Cd body burden by age was estimated by the following equation: Total Cd Body Burden = -4. 5948 + l. 2278 Age - 0. 0121 Age. The highest body burden of Cd was estimated at 26. 5 mg at age 50. 7 years in the Korean general population. The positive correlation between Zn and Cd was observed in renal cortex and liver. CONCLUSIONS: The level of Cd exposure in Korean was found to be lower than in Japanese, but same as or higher than in American and Europeans.

Three hundred and fourty two patients with a fracture of tibial shaft were treated and managed in the Department of Orthopaedic Surgery, Soon Chun Hyang University Hospital from January 1981 to December 1985. In 147 cases, 62 cases had only tibial shaft fracture and 85 tibial and fibular shaft fracture. All of these were treated conservatively by manipulation and cast immibilization. We analyzed the initial fracture characteristics, the treatment employed, and the subsequent complications in fracture healing in a series of patients who had sustained a tibial shaft fracture with and without a fibular fracture. The results were as follows; 1. Duration of average bone healing was more slowly in the patients more than twenty years old who were treated for a tibial shaft fracture with and without a concomitant fibular fracture than in the patients less than twenty years old. 2. Duration of average bone healing was more slowly by one or two weeks in the the group of tibial shaft fracture without fibular fracture than in than in those with fibular fracture. 3. The frequency of delayed union, nonunion, varus malunion and pain in the ipsilateral ankle joint were more increased in the group of the tibial shaft fractures without fibular fracture in than those with fibular fracture. 4. The frequency of valgus malunion was more increased in the group of the tibial shaft fractures with fibular fracture than in those without fibular fracture.

10.Assessing frailty using comprehensive geriatric assessment in older patients with hematologic malignancy
Blood Research 2022;57(S1):S1-S5
The incidence of hematologic malignancy increases with age; thus, the number of older patients who require intensive chemotherapy is expected to increase with the aging population. In Korea, 61.8%, 59.3%, 47.0%, and 46.7% of newly diagnosed cases of multiple myeloma, myelodysplastic syndrome, myeloproliferative disorder, and non-Hodgkin lymphoma, respectively, occurred in patients aged >65 years in 2018. Health status among older patients, defined by frailty, age-related syndrome of physiological decline and increased vulnerability, is associated with adverse health outcomes. Health status is highly heterogeneous among older patients, and treatment outcomes vary according to frailty and physiologic age rather than chronologic age. Comprehensive geriatric assessment (CGA) is a multidimensional and multidisciplinary diagnostic and treatment process that identifies multiple domains, including functional status, cognition, comorbidities, medications, socioeconomic status, and nutritional status, to develop a coordinated plan to improve treatment-related outcomes and quality of life. Frailty can be assessed with CGA findings, and CGA is considered the “gold standard of care” for frail, older patients. Through CGA, unidentified problems can be assessed, and pre-emptive and non-oncologic interventions can be delivered. CGA is an objective and reliable tool for predicting further treatment-related complications and identifying patients for whom intensive chemotherapy with curative intent is appropriate. CGA should be considered a routine practice before starting treatment planning in older patients diagnosed with hematologic malignancies who require intensive chemotherapy. Further study is needed to allocate individualized treatment plans or multidisciplinary geriatric interventions according to CGA results.
