PURPOSE: To evaluate the surgical outcomes of pancreaticogastrostomy (PG) using two transpancreatic sutures with a buttress method through an anterior gastrostomy (PGt), and compare these results with our previous experience with pancreaticojejunostomy (PJ) including the dunking and duct to mucosa methods after pancreaticoduodenectomy (PD). METHODS: In this study, 171 patients who had undergone PD between January 2005 and April 2013 were classified into three groups according to the method of the pancreaticoenteric anastomosis: dunking PJ (PJu group; n = 67, 39.1%), duct to mucosa PJ (PJm group; n = 41, 23.9%), and PGt (PGt group; n = 63, 36.8%). We retrospectively analyzed patient characteristics, perioperative outcomes, and surgical results. RESULTS: Both groups had comparable demographics and pathology, and there were no significant differences in operative time, estimated blood loss, or postoperative hospital stay. Within the two groups, morbidities occurred in 49 cases (10.7%), and were not significantly different between the two groups, excepting postoperative pancreatic fistula (POPF). The PGt group had a lower rate of POPF (18/63, 28.6%) than the PJu and PJm groups (21/67, 31.3% and 19/41, 46.3%; P = 0.048), especially in terms of grades B and C POPF (4/63 [6.3%] in the PGt group vs. 7/67 [10.4%] in the PJu group and 9/41 [22.0%] in the PJm group, P = 0.049). CONCLUSION: The PGt method showed feasible outcomes for POPF and had advantages over dunking PJ and duct to mucosa PJ with respect to immediate postoperative results. PGt may be a promising technique for pancreaticoenteric anastomosis after PD.

BACKGROUND: To evaluate the effects of severe hypoglycemia without hypokalemia on the electrocardiogram in patients with type 2 diabetes in real-life conditions. METHODS: Electrocardiograms of adult type 2 diabetic patients during the episodes of severe hypoglycemia and the recovered stage were obtained and analysed between October 1, 2011 and May 31, 2012. Patients who maintained the normal serum sodium and potassium levels during the episodes of severe hypoglycemia were only selected as the subjects of this study. Severe hypoglycemia was defined, in this study, as the condition requiring active medical assistance such as administering carbohydrate when serum glucose level was less than 60 mg/dL. RESULTS: Nine type 2 diabetes patients (seven men, two women) were included in the study. The mean subject age was 73.2+/-7.7 years. The mean hemoglobin A1c level was 6.07%+/-1.19%. The median duration of diabetes was 10 years (range, 3.5 to 30 years). Corrected QT (QTc) intervals were significantly increased during the episodes of severe hypoglycemia compared to the recovered stage (447.6+/-18.2 ms vs. 417.2+/-30.6 ms; P<0.05). However, the morphology and the amplitude of the T waves were not changed and ST-segment elevation and/or depression were not found during the episodes of severe hypoglycemia. CONCLUSION: In this study, QTc interval prolongation during the episodes of severe hypoglycemia was observed without hypokalemia. Therefore, the distinct alterations in cardiac repolarization during the episodes of severe hypoglycemia may not be associated with hypokalemia.

BACKGROUND: Subarachnoid hemorrhage is a fatal disease relatively common in the East Asian population. It can lead to cardiac arrest in several pathologic processes. We attempted to elucidate the characteristics of out-of-hospital cardiac arrest caused by non-traumatic subarachnoid hemorrhage. METHODS: We conducted a retrospective, observational study in which patients who had visited Samsung medical center emergency room for out-of-hospital cardiac arrest from January, 1999 to December 2008 were enrolled. A total of 218 OHCA patients who had achieved ROSC were investigated by review of medical charts. Excluding those who had worn trauma, we analyzed 22 patients who had been diagnosed for SAH by brain non-contrast CT scan. RESULTS: Median age of aneurysmal SAH-induced OHCA patients was 61 (IQR 54-67) years. Fourteen patients (64%) were female and 15 patients (68%) were witnessed. Besides, 7 patients (32%) had complained of headache before collapse. We also found 11 patients (50%) had been diagnosed with hypertension previously. All of them showed unshockable rhythm (asystole 60%, PEA 40%) initially. Their median duration of ACLS was 10 minutes. Majority of patients died within 24 hours and survivors showed poor neurologic outcome. CONCLUSIONS: Subarachnoid hemorrhage is a relatively uncommon cause of cardiac arrest, and the outcome of OHCA induced by SAH is very poor. However, emergency physicians have to consider the possibility of SAH when trying to determine the cause of arrest, especially when treating patients who have the characteristics described above.

A family of calcium-dependent protein kinases (CDPKs) is a unique enzyme which plays crucial roles in intracellular calcium signaling in plants, algae, and protozoa. CDPKs of malaria parasites are known to be key regulators for stage-specific cellular responses to calcium, a widespread secondary messenger that controls the progression of the parasite. In our study, we identified a gene encoding Plasmodium vivax CDPK4 (PvCDPK4) and characterized its molecular property and cellular localization. PvCDPK4 was a typical CDPK which had well-conserved N-terminal kinase domain and C-terminal calmodulin-like structure with 4 EF hand motifs for calcium-binding. The recombinant protein of EF hand domain of PvCDPK4 was expressed in E. coli and a 34 kDa product was obtained. Immunofluorescence assay by confocal laser microscopy revealed that the protein was expressed at the mature schizont of P. vivax. The expression of PvCDPK4-EF in schizont suggests that it may participate in the proliferation or egress process in the life cycle of this parasite.

Nodular cystic fat necrosis is a distinct benign subcutaneous nodule characterized by encapsulated necrosis of subcutaneous fat in which non-viable adipose cells are pathologically surrounded by fibrous tissue. We report a case of nodular cystic fat necrosis in a 47-year-old woman who presented with a 2-month history of had multiple highly- movable, subcutaneous nodules on both shins and posterior thigh. There was an absence of any noteworthy trauma history. Each lesion showed a highly-migratory property, and could easily be moved about 10 cm in any direction. Plain film revealed multiple radiopaque nodules on the right shin. Calcification and lipomembranous changes, in addition to typical features, were also found on histopathologic examination.

BACKGROUND: Atopic dermatitis (AD) is a chronic, relapsing disease with genetic and environmental background. Many factors may act as triggers and affect the course of the disease. However, little is known about the factors affecting the disease severities in Korean childhood AD. OBJECTIVE: The aim was to document the distinct characteristics of childhood AD in Korea and to determine which manifestations are prone to be present in the settings of different severity of the disease. METHOD: The clinical manifestations, past medical and family history, and inducing or aggravating factors were studied in patients, who participated in the open lectures for childhood AD patients in three provinces of Korea. The severity of the disease was evaluated using the Eczema Area and Severity Index (EASI) and the factors affecting the severity of the disease were determined. Skin prick tests with four allergens, Dermatophagoides pteronyssinus, milk, peanut and egg, were also carried out. RESULTS: Of the 93 patients, 38.7% had the disease onset between the age of three and six, while 17.2% had it between the age of seven and fifteen. Sixty-five percent of the patients had family members with a history of atopic diseases, such as AD, asthma, allergic rhinitis and allergic conjunctivitis. In order of frequency, the patients either had a history of or presently accompanying infantile eczema, allergic rhinitis, asthma or allergic conjunctivitis. Among the patients, 27% took herbal medication. The most frequently involved site was the flexural area. The most common aggravating factors were sweating in hot environment, wool fabric and stress. When AD patients were categorized into mild, moderate and severe groups by EASI, the older onset age, the longer duration, facial distribution, history of taking herbal medication, cholinergic condition, wool fabric and stress were found to be significant factors influencing the severity of the disease. Skin prick test with the four major allergens revealed the highest prevalence in Dermatophagoides pteronyssinus. CONCLUSION: The age of onset of AD was higher than that has been reported. Many suffered from infantile dermatitis and had other accompanying atopic diseases. Aggravating factors should be avoided to minimize the risk of disease aggravation. Based on the fact that late onset age, duration, facial distribution, history of taking herbal medication, cholinergic condition, wool and stress were the statistically significant factors, we may predict the severity or the course of the disease.

Discoid lupus erythematosus (DLE) commonly develops on the sun-exposed area such as the bridge of the nose, malar areas, lower lip and ears. Typically lesions have well-defined discoid erythematous patches with adherent scales, horny plugs, telangiectasia, hypopigmentation and atrophy. Topical, systemic and intralesional injection of steroid and antimalarial drugs have been used. However, the most important treatments in DLE are avoidance of sunlight exposure and daily use of high SPF sunscreen. We treated two DLE patients with autologous suction blister graft (ASBG) which has been widely used for treatment of vitiligo. In general, grafted sites tend to be hyperpigmented after ASBG, so we adopted this characteristic to the treatment of DLE for the purpose of achieving natural sun protection. After one month of ASBG, not only increased pigmentation but also improved skin texture of the lesion was observed. We thought ASBG provided the biologically protective barrier to sunlight and somewhat improvement of DLE lesion. Therefore, ASBG could be regarded as one of the options in the therapeutic modalities of DLE.

Coccidioidomycosis is a systemic infection caused by inhalation of airborne spores of Coccidioides immitis, a fungus found in soil in the southwestern area of United States and in parts of Mexico and South America. Although its human infection has not been reported infrequently in nonendemic areas, it has rarely been done in Korea since first report of a case of systemic coccidioidomycosis with cutaneous lesions. The patient was a 32-year-old male with granulating cutaneous nodules on left side of upper back for 1 month. Three months ago, he had stayed at northern area of Mexico for 2 months with mild transient upper respiratory symptoms during his stay. After he returned to Korea, cervical lymphadenopathy and skin lesions developed. He had also respiratory symptoms such as chest discomfort and mild chest pain and chest X-ray revealed a solitary nodule. The cutaneous nodules of walnut size were removed surgically and he was recieved daily oral medication of itraconazole 400 mg for 10 months showing good clinical response. Even though lung nodule was not disappeared in radiological exam, repeated CT guided biopsy and fungal tissue culture of lung nodule were undertaken with no growth throughout 10 months. After 10 months itraconazole therapy, there was no evidence of clinical relapse and no change on chest film for following 16 months. We report a case of disseminated coccidioidomycosis involving lung, skin and lymph node simmultaneously and successfully treated with both surgical excision and systemic antifungal therapy.

Adenoid cystic carcinoma of the skin is the rarest type of eccrine sweat gland carcinoma. Although it is mostly known as a neoplasm of the salivary gland, it could occur as a primary tumor of the skin. We report a case of primary cutaneous adenoid cystic carcinoma in a 75-year-old male patient with two local recurrences. It was a lobulated tender erythematous nodule on the scalp measuring 2.5x1cm. Histopathologic examination after total excision showed cribriform, tubular, and solid masses of various size and shape involving dermis and the upper part of subcutis including perineural invasion. They consisted of almost uniform basaloid cells surrounded by myxoid or slightly fibrotic stroma. Adjacent organ such as salivary gland, bronchus, esophagus, and regional lymph nodes were examined with no evidence of neoplasm. Systemic evaluation for metastasis were also negative.

The identification of differential gene expression between gray and black hairs is an important study in modern hair pigment research. In this experiment, the authors have applied new methods by the integration of three updated molecular biological tools, T7 RNA polymerase-based RNA amplification, representational difference analysis (RDA), and microarray analysis, to screen the differentially expressed genes in gray and black hairs. The genes more abundantly expressed in black hairs were pigment related proteins, such as Pmel17, 95kD melanocyte-specific secreted glycoprotein, MART-1, tyrosinase, tyrosinase-related protein 1 etc. Also, expression of the selenium-binding protein (hSBP) gene and the spast gene for spastin protein were up-regulated in black hairs compared to those in gray hairs. In gray hairs, many kinds of genes related with keratin, trichohyalin and transmembrane glycoprotein were more expressed. In particular ch 17, hRPK.142_H_19 was expressed in gray hairs as high signal intensity.
