In military training, the knee joint is more susceptible to trauma than any other joint in the body. Chronic knee instability is a difficult problem for both the patient and the orthopaedic surgeon who must correct the disability. To achieve the best possible result, the surgeon must first make the correct diagnosis and be aware of the type or types of instability that exist. There may be associated instability in a rotatory plane as described by Slocum and Larson, and the surgeon must examine carefully for this. Various surgical techniques have been used in the past to repair the knee static stabilizers such as ligaments and capsule. Since the introduction of the dynamic concept of rotatory instability and the need for muscular reinforcement of static repair, most orthopaedists have attempted to back up their reapirs with various types of dynamic stabilization such as the pes anserinus transfer and advancement of semimembranosus. 39 cases of medial instability of the knee joint were analysed clinically in the department of orthopaedic surgery of Busan Armed Froce General Hospital from Feb. 1977 to Feb. 1980 and following results were obtained. 1. All of the cases were military personnels, most of them were privates and P.F.C. showed most frequent incidence in 19 cases (49%). 2. Sports injury was a main causes of the knee instability. 3. The highest incidence in severity of the lesion was grade III in 21 cases (54%). 4. Among 39 cases of ligamentous injuries of medial side, rupture of collateral ligament alone were 30 cases, and mixed injuries with cruciate were 9 cases. 5. The pes transfer was performed in all of the cases with acute medial collateral rupture, and even in the cases with instability after primary repair, good results were obtained by carrying out dynamic muscle or tendon transfer. 6. In some cases, the patient did not feel much discomfort for the remaining static instability in valgus stress test after dynamic reconstruction. This was thought to be overcome by dynamic force during use of the leg. 7. For the purpose to prevent further stretching of repaired ligaments, derotation brace were recommended in 5 cases of dynamic reconstructive surgery.

Subacute thyroiditis is a frequent benign thyroid disease associated with previous viral upper respiratory tract infection. Known complications of this disease are long-standing subclinical hypothyroidism, persistent anterior neck pain and rarely Graves disease. In general, thyroid abscess is an uncommon disease because of anatomic isolation of the gland and its rich system of drainage for blood and lymph. Especially, development of thyroid abscess in subacute thyroiditis is extremely rare phenomenan, but significant bad outcomes can be resulted. Its clinical BACKGROUND containes immune-suppressed state, anatomic defect, presence of underlying other thyroid disease and of non-thyroidal infectious foci. We experienced a case of subacute thyroiditis complicated with streptococcal thyroid abscess during glucocorticoid therapy. The patient was a 19-year-old female who was admitted due to anterior neck pain for 1 month. Typical subacute thyroiditis was suggested from initial laboratory findings including CBC, erythrocyte sedimentation rate, serum T3, T4, TSH levels, thyroid scan & thyroid uptake. But during oral prednisolone therapy, unexpected bacterial thyroid abscess was developed. We report this unusual case with review of literatures.

PURPOSE: To evaluate the radiologic characteristics of sinonasal lymphoma, as seen on CT and MR MATERIALS AND METHODS: In eighteen patients with pathologically-proven non-hodgkin's lymphoma in the sinonasal cavity, CT andMR images were retrospectively reviewed. CT and MR findings were analyzed for tumor location, degree ofinfiltration into the adjacent structure, degree of enhancement, and the presence of bone change. Tthe last-namedwas classified as one of four types : complete destruction, segmental destruction, thinning, or sclerotic change. RESULTS: Masses in the nasal cavity (N=17) and ethomoid sinus (N=16) were most common, and the remainder wereaccounted for by maxillary sinus(N=6), sphenoid sinus(N=2), and frontal sinus(N=2), In 16 cases, the involvementof more than two sinonasal compartments was demonstrated ; the deensity of these masses was shown by precontrastCT to be similar to that of facial muscles ; affer contrast enhancement, all except one (15/16) showed homogeneousenhancement. Tumor infiltration of the adjacent structure was identified in the nasopharynx(N=9), anterior buccalspace(N=7), orbit(n=6), subcutaneous layer of the cheek(N=3), and infratemporal fossa(N=3). Direct extension ofthe tumor from the nasal fossa to the nasopharynx or anterior buccal space was demonstrated. Among 18 cases, bonechange was seen in 12, segmental destruction in eight, complete destruction in six, thinning in two, and scleroticchange in two. Four of the six cases with complete bone destruction showed hyperdense linear density within themass ; CT showed that after treatment, bony regrowth had occurred. In two cases, MRI showed intermediate signalintensity of the masses on T1WI, iso or slightly high signal intensity on T2WI, and moderate enhancement onpostcontrast T1WI. CONCLUSION: On CT, sinonasal lymphoma usually showed homogenous enhancement, extensivelyinfiltration of the adjacent structure, but no massive bone destruction. Hyperdense linear density, suggestingghost bone and seen in spite of massive bone destruction, may be a characteristic finding of sinonasal lymphoma.

PURPOSE: Hibernoma is a very rare benign soft tissue tumor of the hypervascularized brown fat tissue with no malignant potential. MATERIALS AND METHODS: However, it is difficult to differentiate a hibernoma from other malignant tumors, such as liposarcoma using computed tomography and magnetic resonance imaging, and a surgical resection with histological confirmation is the treatment of choice. RESULTS: Histopathologically, hibernoma is composed of brown adipose cells that are polygonal and multivacuolated with a centrally located nucleus and granular cytoplasm, unlike white adipose cells. CONCLUSION: This article describes a patient with a histologically-confirmed hibernoma of the right shoulder.

BACKGROUND: Depression is common in chronic renal failure patients and usually associated with poor appetite. Malnutrition with poor appetite is known to be associated with increased mortality in chronic hemodialysis (HD) patients. So we evaluated the prevalence, risk factors of depression and effects of depression to nutritional status in chronic HD patients. METHODS: Sixty two HD patients (age 48.8+/-11.1 years, diabetes 29%) were investigated. Each patients were interviewed and completed the Beck depression inventory (BDI, 21 items, 0-3 point). To exclude the possible confounding effects of illness and treatment symptoms, cognitive depression index (CDI, a cognitive subset of 15 items selected from BDI) was used as a measure of depression. KT/V and nutritional parameters such as serum albumin, normalized protein catabolic rate (nPCR), subjective global assesment (SGA), body mass index (BMI), triceps skinfold thickness (TSF) and midarm muscle circumference (MAMC) were also measured. RESULTS: Corrected BDI score (CDI score multiplied by 21/15) was 24.9+/-12.7 and the prevalence of depression (corrected BDI score > or = 21) was 64.5%. DM patients had higher CDI score than non DM patient (22.9+/-7.2 vs 15.6+/-9.0). In univariate analysis, CDI score was correlated with age (r=0.39, p<0.01), serum albumin (r=-0.37, p<0.005), nPCR (r=-0.30, p<0.05), SGA (r=-0.42, p<0.05), BMI (r=-0.28, p<0.05), TSF (r=-0.41, p<0.05) and MAMC (r=-0.50, p<0.01). In multivariate analysis, CDI score was the strongest correlate of nPCR, SGA, BMI, TSF and MAMC. But KT/V, hematocrit, erythropoietin usage, plasma bicarbonate, serum parathyroid hormone, c-reactive protein concentration and HD duration had no relationship with CDI score. CONCLUSION: The prevalence of depression in chronic HD patients was high. Diabetes and old agewere important risk factors for depression. It was also concluded that severity of depression was correlated with markers of malnutrition and depression could be a independent risk factor of malnutrition in chronic HD patients.

The aim of this study was to investigate the effects of antidepressant treatment on serum cytokines and nutritional status in hemodialysis patients. Twenty-eight hemodialysis patients with a depressed mood were given 20 mg of fluoxetine for 8 weeks. The degree of depressive symptoms, the serum levels of interleukin-1beta, interleukin- 2, interleukin-6, tumor necrosis factor-alpha, c-reactive protein, and markers of nutritional status were assessed at baseline and after treatment. The outcome was assessed in terms of response to treatment (>50% reduction in the score of the Hamilton depression rating scale). Antidepressant treatment decreased the serum level of interleukin- 1 in both response and nonresponse groups, and increased the serum level of interleukin-6 only in the response group. At baseline, the level of interleukin-6 in the response group was lower than in the nonresponse group. Antidepressant treatment also increased fat distribution significantly in the response group which might have slightly improved the nutritional status. This study suggests that antidepressant treatment improve depressive symptoms and may affect immunological functions and nutritional status in chronic hemodialysis patients with depression.

The objective of this study was to investigate national surgical trends for distal radius fractures (DRFs) in Korea and analyze healthcare institution type-specific surgical trends. We analyzed a nationwide database acquired from the Korean Health Insurance Review and Assessment Service (HIRA) from 2011 to 2015. International Classification of Diseases, 10th revision (ICD-10) codes and procedure codes were used to identify patients aged ≥ 20 years with newly diagnosed DRFs. A total of 459,388 DRFs occurred from 2011 to 2015. The proportion of DRF cases treated by surgery tended to increase over time, from 32.6% in 2011 to 38.3% in 2015 (P < 0.001). Open reduction with internal fixation (ORIF) using a plate steadily gained in popularity each year, increasing from 39.2% of overall surgeries in 2011 to 60.9% in 2015. The type of surgery for DRFs differed depending on the type of healthcare institution. ORIF (91%) was the most popular procedure in tertiary hospitals, whereas percutaneous pinning (58%) was most popular in clinics. In addition, general hospitals and hospitals with 30–100 beds used external fixation more frequently than tertiary hospitals and clinics did. Overall, our findings indicate that surgical treatment of DRF, particularly ORIF, continues to increase, and that the component ratio of operation codes differed according to the healthcare institution type.

BACKGROUND AND OBJECTIVES: Several treatment options have been introduced to control Meniere's disease (MD). Among them, intratympanic injection of gentamicin (ITGM) is now accepted as a standard treatment method for intractable vertigo in patients with hearing impaired MD. The purpose of this study was to analyze the clinical course and treatment flow in patients with MD and to analyze the efficacy and problems after ITGM. SUBJECTS AND METHOD: A retrospective study was performed on 458 patients who were diagnosed as definite MD from May 2003 to October 2007 and were followed up at least 1 year. The authors investigated the course of disease and the results in our patients according to the treatment options. Several clinical parameters including frequency of vertigo, audiometry, caloric and rotation test were reviewed and analyzed according to the guideline of the AAO-HNS (1995), if necessary. Efficacy and problems after ITGM were reviewed. RESULTS: Among 458 patients, vertigo was resolved or improved in 399 patients (87.1%) with medical management. Fifty-nine patients needed further treatment (endolymphatic sac decompression: 4, Meniette: 2, ITGM: 53). Among 53 patients who got ITGM, 40 patients were followed up for more than 1 year after injection. Thirty-six patients (87.5%) showed successful control of vertigo. The average pure-tone threshold was changed from 54.1 dB to 56.9 dB after treatment. Three patients (7.5%) revealed more than 20 dB aggravation. CONCLUSION: Vertigo was controlled by supportive treatments or medication in 87% of definite MD patients. And ITGM could effectively and reasonably control vertigo for intractable MD patients.

BACKGROUND: Since Plasmodium vivax malaria reemerged in Korea in 1993, a number of patients with malaria have been reported. We analyzed the cases with malaria who lived in Chuncheon and neighboring communities to find out clinical manifestations, laboratory findings and the differences in clinical findings compared to previous studies. METHODS: We reviewed the clinical records of the cases who were confirmed as malaria by peripheral blood smear in Chuncheon Sacred Heart Hospital from July, 1998 to Octorber, 2001. RESULTS: Forty-four cases were included. All cases were Plasmodium vivax with high fever, but tertian fever developed only in 15 patients (35.7%). A number of cases showed various symptoms including headache, abdominal pain, nausea, vomiting. Of the all cases, 41 cases (93.2%) developed malaria between June and September. Thrombocytopenia was prominent finding which was noted in 75% of the cases at diagnosis, and recovered during or after treatment. Other laboratory abnormalities such as anemia, elevated transaminases, coagulopathies, and elevated LDH level were also noted. Five patients were performed CSF studies, one patient showed pleocytosis in CSF. CONCLUSION: We observed that only 15 patients (35.7%) had tertian fever, the others had variable fever patterns. Thrombocytopenia was the prominent findings. Therefore we suggest that malaria should be included in the differential diagnosis of febrile diseases which developed from June to September regardless of the fever patterns.

Anatomical lesions of hypothalamic area associated with hypodipsic hypernatremia have been reported only rarely. We report here a case of hypodipsic hypernatremia induced by a hypothalamic lesion. A 25-yr-old man, who had been treated with radiation for hypothalamic tumor 5-yr before, was admitted for evaluation of hypernatremia and hypokalemia. He never felt thirst despite the elevated plasma osmolality and usually refused to drink intentionally. Plasma arginine vasopressin (AVP) level was normal despite the severe hypernatremic hyperosmolar state and urine was not properly concentrated, while AVP secretion was rapidly induced by water deprivation and urine osmolality also progressively increased to the near maximum concentration range. All of these findings were consistent with an isolated defect in osmoregulation of thirst, which was considered as the cause of chronic hypernatremia in the patient without an absolute deficiency in AVP secretion. Hypokalemia could be induced by activation of the renin-angiotensin-aldosterone system as a result of volume depletion. However, inappropriately low values of plasma aldosterone levels despite high plasma renin activity could not induce symptomatic hypokalemia and metabolic alkalosis. The relatively low serum aldosterone levels compared with high plasma renin activity might result from hypernatremia. Hypernatremia and hypokalemia were gradually corrected by intentional water intake only.
