1.Relationship between Direct Measured and Calculated Ionized Calcium in Maintenance Hemodialysis Patients.
Korean Journal of Nephrology 1998;17(6):919-925
It is important to maintain normal calcium concentration especially ionized calcium concentration in chronic renal failure patients on hemodialysis. The direct measurement of ionized calcium is less commonly used due to a lack of automated equipment as well as the cost of laboratory equipment. Numerous formulas for adjusted total calcium and calculated ionized calcium are used in clinical practice. We examined the relationship between direct measured ionized calcium and total calcium, corrected total calcium, calculated ionized calcium (formula of Nordin et al) in 53 chronic renal failure patients on hemodialysis. The results were as follows; 1) In predialysis group, plasma total and ionized calcium levels were 2.36+/-0.26, 1.04+/-0.21mmol/L respectively, and higher than normal controls. The correlations between plasma ionized calcium and total calcium, calculated ionized calcium, corrected total calcium were r=0.72 (P=0.0001), r=0.81 (P=0.0001), r=0.65 (P=0.0001) respectively. The plasma ionized calcium level was not correlated with the level of albumin, pH, phosphate, parathyroid hormone. 2) The plasma total and ionized calcium levels were significantly increased with hemodialysis and values were 2.49+/-0.14mmol, 1.14+/-0.14mmol/L respectively. The correlation between ionized and total calcium was r=0.41 (P=0.0021). These results suggested that the calculated ionized calcium (formula of Nordin et al) and total calcium can be used to predict the plasma ionized calcium level in chronic renal patients on hemodialysis.

2.A Case of laparoscopic cystectomy for large adenomyotic cyst within myometrium with bilateral endometriomas.
Korean Journal of Obstetrics and Gynecology 1999;42(1):158-162
Adenomyotic cysts are not uncommon disease, but their sizes are mostly lesser 5 mm. Reports of large adenomyotic cyst ( >5 mm ) are vere rary. These large sized hemorrhagic cysts arise from small sized cyst and may be caused by progressive expansion of cyst due to progressive menstrual bleeding. And the active secreting of cystic wall may play a part in making the large cyst. Authors observed a case of large adenomyotic cyst within myometrium occuring in o 39-year-old woman, and she was accompanied with both ovarian endometriomas. The cyst was 3 *3 cm sized, and had chocolate-colored thick viscous contents. Histologically, cystic wall was lined with endometrial type epithelium. Epithelium were composed of single layer columnar, partly ciliated cells. Stroma under glandular epithelium were thin throughout the cyst and resembled morphologically endometrial stroma in endometriosis and had red cells and hemosiderin-laden macrophages in places. We experienced one case of large adenomyotic cyst, so we report the case with a brief review of the concerned literatures.

3.A Clinical Analysis on the Patients of Orient-Medical Therapies in Emergency Department.
Journal of the Korean Society of Emergency Medicine 1997;8(4):553-558
We have observed that many patients who were under the treatment of orient medicine at the emergency department of our hospital but no data are available describing the medical habits of these patients. We therefore surveyed these patients seeking care in our ED to characterize their use of orient-medical therapies.4 analysis on the 427 patients who visited our ED and were under the treatment of orient medicine from Jan. 1996 to Jun. 1996 was carried out The results were as follows 1) There was no difference in the sex ratio (m:f=1:0.93). 2) With respect to the age groups of in patients, feat numbers of elderly people(50-year and 60-year old age group, over 60%) visited to our ED. 3) In the leading causes for visit to orient-medical therapy, cardiovascular disease ranked at the top(40%), followed by injury, gastrointestinal disease, and respiratory disease in decreasing order of frequency.4) The total numbers of CVA patients admitted to Oriental medicine were 105 patients. 5) The duration of admitted patients to Oriental medicine was prolonged for elderly patients.6) In the distribution of severity(AVPU) of adimitted patients, the number of patients with alert was 12 and verbal response was 91 painful response was 2 and unresponse was 0.

The traditional aesthetic blepharoplasty has limitations in correcting the heaviness and bulkiness of the lateral orbital region. These limitation is due to presence of sub-orbicularis oculus fat(SOOF) which is defined as that layer of fibrofatty soft tissue deep to the orbicularis oculus muscle, superficial to orbital septum and orbital rim, and extending medially from supraorbital nerve and laterally to varying distance over the lateral upper orbit. Therefore authors performed resections of the SOOF in conjunction with aesthetic blepharoplasty in 15 patients, who visited the clinic with complaints of thickness and heaviness over their lateral eyebrow, often accompanied by tired or sad-looking appearance. We believe that in these patients the heaviness. bulkiness and fullness in the lateral upper orbital region were corrected effectively and smoothly in aesthetical aspect. No patients developed postoperative hematoma, dry eye syndrome, lacrimal gland injury and significant paralysis of the orbicularis oculus of corrugator muscle. Our department performed the SOOF resection to those who had bulkiness and heaviness in lateral upper orbital region. From this experience, the SOOF resection would appear to be a useful adjunct to standard blepharoplasty technique in selected patients. Since we achieved a satisfactory result aesthetically through this method on patients who showed proper indications, we are recording the indications, operative techniques and complications in addition to review of reference.

In cholangiographic techniques, the close relationship between choledochal cyst and anomalous union of pancreaticobiliary duct has attracted medical attention. There have been rare cases in which the papilla of Vater was found in a position other than its normal position, and such cases have been reported sporadically. However, such cases are interesting in the anatomical context. In this review, we present our experience of choledochal cyst in a 30-month-old boy in whom the papilla of Vater was positioned in the third portion of the duodenum.

Injectable Collagen Implan, is composed of purified bovine dermal collagen emulsified in saline and lidocaine(0.3%) base, and has been promoted for correction of soft tissue contour defects. Although collagen is a relatively nontoxic, nonimmunologic and biolegically nonreactive biomaterial, some side reactions have been reported. We report herein a case of cutaneous side reaction to collagen implantation in a 38-year-old female. The patient presented with puritic, irritating, multiple, erythematous nodules on both the temporal and interorbital area, which had been observed since 1 day after collagen(KOKEN ATELOCOLLA-GEN IMPLANT-Japan) implantation. Histopathologic findings showed dense infiltration of acute and chronic inflammatory cells in the dermis, especially the perivascular and periadnexal area.

PURPOSE: The aim of this study is to better understand the pattern and nature of reverse redistribution (RR) in myocardial perfusion imaging. MATERIALS AND METHODS: In consecutive 20 acute myocardial infarction (MI) patients, frequency of RR was correlated with that of subendocardial MI that was detected by myocardial contrast echocardiography (MCE). RR was judged to be present when there was more than one grade of worsening in perfusion at 24 hr delayed images compared with the initial rest images. MCE evaluated the significant lack of opacification in the subendocardial myocardium relative to the subepi-cardial myocardium to suggest the subendocardial MI. Kendall's nonparametric correlation coefficiency was calculated. RESULTS: Concordant cases were 15 of 20 (75%) and correlation was statistically significant (p=0.0285). CONCLUSION: Our results suggested that RR was correlated with MCE-detected nontransmural MI.

The superior volume maintenance of membranous over endochondral bone grafts, which was shown in several studies has provided the basis for its preferred clinical use as an onlay grafting material on the craniofacial skeleton. The scientific rationale for this seeming embryological advantage, however, has never been proven, Since the cortical component of membranous bone is proportionally greater than that of endochondral bone, it follows that membranous grafts would show greater volume maintenance over time. Our hypothesis is that the pattern of onlay bone graft resorption is primarily determined by a graft's micro-architecture (relative cortical and cancellous composition) rather than its embryololgical origin(membranous versus endochondral). Fourty adult New Zealand white rabbits were used for this study. There were 8 animals in each of 4 groups. The rabbits of each group were sacrificed at 3, 8, and 16 weeks. Four types of grafts were placed subperosteally, onto each rabbit's cranium: a hydroxyapatite, a cortical bone graft of membranous origin, a cortical bone graft of endochondral origin and a cancellous bone graft of endochondral origin. Membranous bone grafts were obtained from the lateral mandible and endochondral bone grafts were obtained from the ileum. In order to determine post-sacrifice volume and density of the bone grafts, a caliper technique and bone densitometry(bone densitometer: LUNAR, DPX-L, U.S.A.) were performed on all of the bone grafts. Bone graft specimens were histologically examined at 3, 8, and 16 weeks.The measurement of volume and density show that there is a statistically greater resumption in the cancellous endochondral bone grafts for all parameter, compared to either the endochondral or membranous cortical bone grafts or hydroxyapatite at all time points(p< 0.05). In addition, there is no significant difference in the resorption rates between the endochondral and membranous cortical bone grafts for all parameters at all time points. By placing cortical bone grafts and cancellous bone grafts on the recipient sites separately, we have shown that the former grafts maintain their volumes, widths and projections significantly better than the latter grafts. Futhermore, we found no statistical difference in resorption rates between the two cortical bone grafts of different embryologic origins, a finding which has never been previously shown. Bone volume fraction, measured with bone densitometry, was shown to be higher in cortical bone than in cancellous bone at all time points, further illustrating the differences between cortical and cancellous bone.From our results, we believe cortical bone to be a superior onlay-graftiong material, independent of its embryololgic origin.

Journal of the Korean Child Neurology Society 1999;7(1):79-88
PURPOSE: Epilepsy is generally defined as a chronic condition characterized by recurrent unprovoked seizure. It is still controversial whether the long-term antiepileptic drugs(AED) treatment will be necessary in children with first unprovoked seizure. Cognitive and behavioral side effects of AEDs are especially important in developing children. Therefore the rationale of AED treatment in the children with first unprovoked seizure depends upon the seizure recurrence rate and presence of risk factors related with seizure recurrence. We are going to evaluate the risk of seizure recurrence and risk factors after a first unprovoked seizure in children. METHODS: One hundred fifty eight patients presented with a first unprovoked seizure from July, 1994 to June, 1999 were prospectively followed by regular epilepsy clinic visit or telephone interview for a mean of 27 months. We analyzed overall recurrence risk and risk factors of seizure recurrence(EEG finding, etiology of seizure, seizure type, history of prior febrile convulsions, neurodevelopmental status prior to first seizure, presence of a Todd's paresis, family history of seizures, a seizure occuring while asleep, and duration of seizure) by Cox's proportional hazards model and Kaplan-Meier survival analysis. RESULTS: In 158 patients with first unprovoked seizure, 61 (39%) patients experienced subsequent seizure. The cumulative risk of seizure recurrence was 28.5, 37.6, and 42.3% at 6, 12, and 18 months. The median time to recurrence was 3 months, with 72% of recurrence occurring within 6 months, 92% within 1 year, and 100% within 2 years. On univariate analysis, risk factors for seizure recurrence included an etiology of seizure and abnormal EEG. In idiopathic cases, the risk factor was an EEG abnormality. CONCLUSION: Many of the children with a first unprovoked seizure will not have recurrences. The recurrence risk of a first unprovoked seizure in children have statistically correlated with the etiology of seizure(cryptogenic and symptomatic) and abnormal EEG. Children with an idiopathic first seizure and a normal EEG have a particularly favorable prognosis.

Clinics in Shoulder and Elbow 2016;19(4):237-240
Retear patterns after arthroscopic rotator cuff repair are classified into two patterns according to retear location. Type 1 is when the retear pattern occurs directly on the tendon at the bone repair site using the suture anchor repair method. Type 2 is when the retear pattern occurs at the musculocutaneous junction with a healed footprint in patients who undergo the suture bridge method. Here, the authors report another retear pattern, which was identified as a type 2 retear on magnetic resonance imaging in patients who had undergone arthroscopic rotator cuff repair by the suture-bridge technique. This pattern was different from the type 2 retear and occurred at the portion of the cuff away from the healed rotator cuff under the view of the arthroscope.
