Grice extra-articular subtalar arthrodesis has been performed as either a temporizing or a definite procedure in young children to correct the dynamic hindfoot valgus deformity without affecting subsequent growth of the foot. Fifty eight extra-articular subtalar arthrodesis in thirty patients, performed at Seoul National University Children's Hospital from setpember 1985 to June 1989, were retrospectively reviewed to evaluate the clinical and radiographic results. There were 52 valgus feet in 26 patients and 6 varus feet in 4 patients secondary to cerebral palsy, meningomyelocele, congenital snomalies, and other neuromuscular diseases. In many instances, additional tendon surgeries were also required to correct deformities or achieve the muscle balance. The review consisted of personal interview, physical examination, and radiological assessment. On physical examination, preoperative hindfoot valgus deformty(mean: 14.3°clinically) was well corrected, postoperative hindfoot valgus ranging from neutral to valgus 5°clinically in 35 of 52 cases(67.3%). Correction of the lateral talocalcaneal angle on standing lateral radiographic view averaged 8.5 degrees(from 57.3 degrees preoperatively to 37.6 degrees postoperatively). In valgus feet, there were 3 cases with mild pain around the ankle joint. There were 5 cases of graft resorption and 2 cases of nonunion. Graft failure was more frequent when the proximal end of the graft was directed anterior to the weight bearing axis. With original Grice subtalar arthrodesis, satisfactory results were obtained in 34 of 52(65.4%) hindfoot valgus feet. In 6 varus feet, there were 1 undercorrection and 2 recurrence of varus deformity. We re-emphasize the importance of strict operative technique to obtain satisfactory results. We also believe that Grice procedure may be used for the correction of subtalar instability in selected cases of varus foot before muscle baancing procedures.

Here, we report a case of newly diagnosed diabetes, with concurrent pancreatic cancer manifested as hyperglycemic crisis, and aggravated by urinary tract infection. We summarize the initial clinical manifestations and pertinent laboratory, radiologic, and clinical findings in an elderly patient with hyperglycemic emergency. A review of the documents involving pancreatic tumors and hyperglycemic hyperosmolar state, which is an acute complication of diabetes mellitus, is presented. In the absence of other identifiable conditions, it is reasonable to speculate that some factor (or factors) produced by the tumor had a role in the metabolic decompensation. In addition, this discussion should be more carefully considered in the aged people group.

The scabies mite is an ectoparasite, which is able to infest humans. The incidence of scabies decreased during the past 20 years in Korea. However, the incidence is likely to increase again, and may be delayed or missed diagnosis recently. Its clinical presentation is typical, although in a host with compromised immune system, like the mentally retarded and elderly patients, the clinical presentation may be altered. Because a delay in diagnosis may induce rapid spread of the scabies mite, immediate diagnosis and treatment are necessary. We report two cases of scabies in elderly patients from different nursing homes. These patients were transferred to our center for treatment of pneumonia and chronic renal disease. They revealed pruritus and skin rashes after the treatment of further underlying diseases. We consulted to a dermatologist because of worsening symptoms, despite an application of medication with antihistamine and topical steroid, scabies was diagnosed. The symptom improved with topical 1% gamma-benzene hexachloride, an effective scabies drug. We suggest that geriatrists should suspect scabies who presents with pruritus that is persistent or resistant to conventional treatment, especially patients transferred from nursing homes.

BACKGROUND AND OBJECTIVES: There are several evidences of reduced cochlea blood flow after noise exposure in the cochlea. However, the pathophysiology of blood flow change is still obscure, and endothelins, proteins that constrict blood vessels and play a key role in vascular homeostasis using its receptors may have importance in this respect. In this study, we investigated the expression changes of endothelin-1 (ET-1), endothelin receptor A (ETAR) and B (ETBR) according to auditory threshold change after noise exposure. MATERIALS AND METHOD: Mice were exposed to different noise to generate transient (group 2) and permanent threshold shift (group 3), respectively. Auditory threshold shifts were evaluated with auditory brainstem response and expression changes of ET-1, ETAR and ETBR after noise exposure were evaluated by immunohistochemistry and real time RT-PCR. RESULTS: After noise exposure, the increased ET-1, ETAR and ETBR immunoreactivities were observe in stria vascularis, spiral ligament and spiral ganglion neuron. ET-1 mRNA expressions increased after noise exposure in both group 2 and group 3 compared to those of the control group. At 2 weeks after noise exposure, however, the ET-1 mRNA expressions in group 3 increased compared to that of the control but decreased compared to that of group 2. On the other hand, ETAR mRNA expression increased at 2 weeks after noise exposure in both groups, just after noise exposure in group 2 and at 2 weeks after noise exposure in group 3. CONCLUSION: These results suggest that expression changes of ET-1, ETAR and ETBR might be associated with hearing threshold shift and recovery after noise exposure in the cochlea.

Hyperkalemic periodic paralysis is characterized by episodic flaccid paralysis of the skeletal muscles due to an increase in serum potassium concentrations. Primary hyperkalemic periodic paralysis is caused by point mutations in SCN4A, encoding a voltage-gated skeletal muscle sodium channel. However, hyperkalemia-related diseases, such as renal failure, adrenal insufficiency, hypoaldosteronism, and chronic diuretic use, can induce secondary hyperkalemic periodic paralysis. Diagnosis of this disease is based on clinical features, nerve conduction studies, and a DNA sequence analysis. In cases of diagnostic uncertainty, a provocation test can be used to ensure the correct diagnosis. Here, we report a case of secondary hyperkalemic periodic paralysis with hyperkalemia that was induced by diabetic nephropathy, and review the relevant literature.

PURPOSE: We purpose to determine the correlation of HER-2/neu and paxillin expression in ductal carcinoma in situ (DCIS), invasive ductal carcinoma with ductal carcinoma in situ (IDC with DCIS) and mucinous carcinoma. METHODS: To evaluate the expression of HER-2/neu and paxillin, the immunohistochemical staining was performed for 13 cases of DCIS, 13 cases of IDC with DCIS and 6 cases of mucinous carcinoma. RESULTS: The DCIS and IDC were associated with infiltration of the inflammatory cells, especially in the comedo type and solid type of tumor. In cases with infiltration of the inflammatory cells, HER-2/neu and paxillin were strongly expressed. When comparing the expression level of HER-2/neu from adjacent normal tissue between DCIS and IDC with DCIS, expression of HER-2/neu was similar to that of normal tissue adjacent to DCIS. However, in the adjoining normal ductal epithelial cells, paxillin was highly expressed in cells of all of the tumor types, and especially for IDC with DCIS. HER-2/neu and paxillin were not expressed in mucinous carcinoma cells in all cases. CONCLUSION: HER-2/neu in the DCIS and IDC with infiltration of inflammatory cells shows higher expression than non-inflammatory DCIS and IDC. If normal duct epithelial cells show a high level of HER-2/neu expression, the epithelial cells have a high probability of transformation into anaplastic cells. However, paxillin appears to have no value as a prognostic factor. The difference of expression of HER-2/neu between IDC with DCIS and DCIS suggests a different origin of tumor cells. The growth pattern of mucinous carcinoma cell is different from the that of DCIS or IDC cell, which grow slowly.

OBJECTIVE: Onion and garlic are a commonly consumed food in the Korean population. But these food materials have rarely been studied for their allergenic potentials. We analyzed the sensitization rate of garlic and onion using multiple allergen simultaneous test (MAST)-immunoblot assay. METHODS: From January 2009 to December 2013, we analyzed the results of the MAST immunoblot assay performed in 2,691 allergy patients at Soonchunhyang University Cheonan Hospital, retrospectively. RESULTS: Among 2,691 patients, 1,063 were under 18 years old, and 1,628 were over 18 years old. In the all age groups, 29 patients (1.08%) were positive to garlic, 54 patients (2.01%) were positive to onion and one patient was positive to garlic and onion and others. A total of 84 patients (3.12%) were positive to garlic or onions. In infants under the age of 2 years, garlic was the seventh and onion was the nineteenth common food allergen, and onion was more common than rice. While getting older, the sensitization rate of garlic decreased (P<0.001), but onion increased (P<0.01). CONCLUSION: Using one of the semi-quantitative methods, MAST immunoblot assay, we realized that the sensitization rate of garlic was higher than rice or wheat in infants. We presume further studies on the role of garlic and onion in food allergy are needed.
