Ki-1 monoclonal antibody is a well known marker for Reed-Sternberg cells in Hodgkin's disease, but also occasionally reacts with activated lymphoid cells of either benign or malignant nature. Recently, Ki-1 antibody positive Non-Hodgkin's lymphoma, usually of large cell and/or polymorphous type, has been reported in the lymph nodes, skin, soft tissue, and stomach, but not in the bone. We report a case of multifocal primary bone lymphoma in a seven-year old body involving the left shoulder and right frontal bone, which proved to be a large cell, polymorphous lymphoma, helper T-cell type expressing Ki-1 antigen.

Purpose: This experimental study with nonequivalent control group and pre/post-tests aims to investigate the effects of a complex leg exercise program on severity of restless legs syndrome, sleep quality, depression, and physical performance in patients with maintenance hemodialysis. Methods: Patients in the experimental group were provided with the leg exercise program three times a week for eight weeks, a total of 24times, through watching videos during hemodialysis from August 1, 2017 to October 25. The experimental group and control group consisted of 22 people each. Data were analyzed using descriptive statistics, x2 test, Fisher's exact test, and independent t-test utilizing SPSS/WIN 22.0. Results: After providing with the leg exercise program, these were level of restless legs syndrome and depression were significantly decreased in the experimental group (t=2.79, p=.032; t=0.53, p=.036, respectively). However, sleep quality and physical performance did not have significant difference between the two groups (t=0.02, p=.947; t=1.74, p=.957, respectively). Conclusion A complex leg exercise program appears to be beneficial in improving restless legs syndrome and depression in maintenance hemodialysis patients with restless legs syndrome.

OBJECTIVES: Apathy Evaluation Scale (AES) is one of the most frequently used scales to evaluate apathy. The purpose of this study was to evaluate the reliability and validity of the Korean version of the AES (K-AES) and to apply the K-AES in examining the characteristics of apathy in the Korean patients with schizophrenia. METHODS: 129 healthy people and 29 patients with schizophrenia have been evaluated using the K-AES, Physical Anhedonia Scale (PAS), Social Anhedonia Scale (SAS), and the Beck's Depression Inventory (BDI). Split-half reliability and internal consistency were evaluated and factor analysis and correlation analysis was conducted. Between-group comparison was conducted using independent sample t-tests. RESULTS: K-AES showed good reliability and validity. Factor analysis confirmed 3 factors, which represented interest and drive, initiative, self-awareness and self-assessment. Patients with schizophrenia showed significantly higher K-AES and BDI scores than the healthy group. K-AES scores in patients with schizophrenia were significantly correlated with the PAS score, but did not correlate with SAS and BDI scores. CONCLUSION: This study demonstrates the reliability and validity of the K-AES. Our findings also suggest that the K-AES may be a reliable instrument in assessing apathy as a negative symptom in patients with schizophrenia.

BACKGROUND: Dermatitis occurring after ingestion of the urushiol chicken is quite common in Korea. Although many cases of the systemic contact dermatitis due to urushiol chicken have already been reported, systemic study on its epidemiology is not done yet. OBJECTIVE: To elucidate the demography of the eaters of the urushiol chicken with its general understandings in society and the incidence of the resultant systemic dermatitis. METHODS: By the help of the patients who developed the dermatitis, all the persons who ate it together with the patients were interviewed. RESULTS AND CONCLUSION: l. 171 eaters of the urushiol chicken(125 male and 46 female) were enrolled in this study(M:F= 3.1:1). The age group in 4th decade was the most common in male, the 5th decade in female. The age prevalence of the systemic contact dermatitis corresponded to the age prevalence of the eater. 2. Incidence rate of systemic contact dermatitis among the eaters was 32.2% (55/171). Incidence rate according to each age group were as follows : 0% in 2nd decade, 33.3% in the 3rd decade, 32.4% in 4th decade, 32.8% in 5th decade, 33.3% in 6th decade, 25% in the 7th decade. 3. One third (57/171) of the eaters ate the urushiol chicken to strengthen their internal organs, especially stomach, which they believed to be weak 70 persons (40.9%) ate it at home, 101 persons (59.1%) ate it at a restaurant. 4. Out of 67 persons having past history of allergic contact dermatitis to Rhus tree, 28 persons (41.8%) showed systemic contact dermatitis. Out of 104 persons without past history of allergy to Rhus, 27 persons (26.0%) showed systemic contact dermatitis.

PURPOSE: This study aims to identify perception, performance, and the related factors of performance in regards to patients' medical information protection among allied health college students. METHODS: Four hundred twelve subjects from three colleges located in Jeonbuk and Kyungbuk province consented to participate. Data was collected from November 28 to December 15, 2012. To assess perception and performance in regards to patients' medical information protection, a self-reporting questionnaire was used. Data was analyzed via SPSS 18.0 program. RESULTS: The score of perception and performance about patients' medical information protection were 4.07 and 3.56, respectively. All item's scores of performance were significantly lower than those of perception. The perception score was significantly different according to recognition of hospital ethics code (t=1.95, p=.052), and recognition of association ethics code (t=2.88, p=.004). The performance score was significantly different according to gender (t=-3.32, p=001), major (F=14.41, p<.001), clinical practicum hospitals (F=8.22, p<.001), and method of electronic medical record access (F=3.23, p=.023). The factors influencing performance were perception(beta=.46, p<.001), duration of clinical practice(beta=-.36, p<.001), and gender(beta=.09, p=.033). CONCLUSION: In order to improve performance in regards to patients' medical information protection of allied health college students, we should develop ethical education programs and standardize them through multidisciplinary collaboration.

Pseudohypoparathyroidism (PHP) is a rare clinical type of hypoparathyroidism. The patients with PHP show classic clinical and biochemical features of hypoparathyroidism, but elevated serum level of parathyroid hormone (PTH) and characteristic physical appearances termed 'Albright's hereditary osteodystrophy' (AHO). PHP is classified into types Ia, Ib, Ic and II according to the presence of AHO phenotype and the mechanism of PTH resistance. We experienced a case of PHP in a 12 year-old girl with carpopedal spasm, syncope and partial AHO. She showed very low serum calcium level (1.4 mmol/L), high phosphorus level (3.62 mmol/L) and high immunoreactive PTH level (186.6 ng/L). In the Ellsworth-Howard test, urinary cyclic adenosine monophosphate and phosphorus levels after an exogenous PTH injection remained unchanged. Therefore, we were able to classify the patient as either PHP type Ia or Ic. After the patient had been treated with daily calcium carbonate (1 g), cholecalciferol (250 IU) and calcitriol (0.5 microgram), her neurological signs and symptoms as well as her biochemical abnormalities of hypocalcemia and hyperphosphatemia were improved.

Peutz-Jeghers syndrome is a rare autosomal dominant disorder in which multiple hamartomatous polyps are present in the gastrointestinal tract in association with distinctive mucocutaneous pigmentation. A single hamartomatous polyp arising in a patient without pigmentation or familial history of Peutz-Jeghers syndrome is termed a solitary Peutz-Jeghers polyp; such a case is rare and would result in a case report being presented even in other countries. We experienced two cases of a solitary Peutz-Jeghers polyp that developed in the rectum, and report the cases with a review of the literature.

BACKGROUND: It has been reported that nail psoriasis is common in psoriatic arthritis (PsA) patients, however, studies on the prevalence of PsA with nail psoriasis and the relationship between the severity of the diseases has not previously been reported in Korea. OBJECTIVE: The aim of this study was to investigate nail psoriasis and its relation to psoriasis and PsA. METHODS: After researching past medical records, 48 patients with nail psoriasis and 247 patients without nail psoriasis were enrolled in this study. Nail psoriasis was classified according to the morphologic types of nails and severity was evaluated using the modified nail psoriasis severity score index (mNAPSI). We assessed the severity of psoriasis and PsA by psoriasis area and severity index (PASI), and swollen and tender joint counts (STJC), respectively. Finally, we analyzed the relationship between mNAPSI, PASI, and STJC. RESULTS: Nail involvement was observed in 48 (16.3%) of 295 patients. Prevalence of PsA was higher in nail psoriasis (31.3%) than in uncomplicated psoriasis (9.3%, p<0.001). mNAPSI showed a positive correlation with STJC (p=0.002, Pearson correlation=0.427), but not with PASI (p=0.094, Pearson correlation=0.202). CONCLUSION: The results show that PsA is more common and severe in psoriatic patients with nail involvement than in uncomplicated psoriasis. Clinicians should be alert to nail involvement in psoriatic patients, as it could be related to the disease course and prognosis of PsA.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) occasionally fails due to surgically altered anatomy, difficult cannulation, or poor general condition. This study evaluated the safety and effectiveness of percutaneous transhepatic papillary balloon dilatation (PTPBD) for managing extrahepatic bile duct stones. METHODS: Between 2001 and 2010, 17 out of 509 patients with extrahepatic bile duct stones and acute cholangitis were enrolled retrospectively. After PTPBD of the sphincter, the stones were extracted using an occlusion balloon to push the stone over a guidewire into the duodenum. The procedure success was evaluated based on residual stones. In addition, the size and number of stones and complications were analyzed. RESULTS: Of the 17 patients, nine had a previous gastrectomy, four had poor general condition, and four had unsuccessful cannulation. The stone diameter ranged from 8 to 25 mm. Seven, five, and five patients had one, two, or three or more stones, respectively. The results were successful in 16 out of 17 patients, with no residual stones. Treatment failed in one patient, who was then treated with the rendezvous technique with endoscopy. No procedure-related major complication occurred. Three patients had mild transient elevations of the serum amylase levels. CONCLUSIONS: PTPBD was safe and effective for managing extrahepatic bile duct stones in patients with unsuccessful or contraindicated ERCP.
