Objective To compare iso-osmolar iodixanol and low-osmolar iohexol for the incidence of contrast- induced nephropathy(CIN) in patients with chronic congestive heart failure undergoing coronary interventional therapy. Methods The study included 220 consecutive patients with chronic congestive heart failure and undergoing coronary angiography (CAG) with or without percutaneous coronary intervention (PCI) bewteen Janurary 2015 and May 2016. Study participants were divided into two groups by random digits table:iso-osmolar group (110 patients) and low-osmolar group (110 patients). The patients in iso-osmolar group were given iodixanol, and the patients in low-osmolar group were given iohexol. Serum creatinine (SCr), glomerular filtration rate (GFR) and cystatin C (CysC) were detected before the procedure and on the first, third day after the procedure. Then, the incidence of contrast-induced nephropathy (CIN) in two groups within 72 h of the procedure were observed and compared. Results The levels of SCr, GFR, CysC before operation had no significant differences (P>0.05). The levels of SCr in two groups on the first day after operation were increased, but there was no significant difference between two groups (P>0.05). On the first day after operation, the level of GFR in iso-osmolar group was higher than that in low-osmolar group, the level of CysC in iso-osmolar group was lower than that in low-osmolar group, and there were significant differences (P<0.05). On the third day after operation, the level of GFR in iso-osmolar group was higher than that in low-osmolar group, the level of CysC in iso-osmolar group was lower than that in low-osmolar group, and there were significant differences (P<0.01). The overall incidence of CIN was 20.9%(46/220). The incidence of CIN in low-osmolar group was 29.1%(32/110), in iso-osmolar group was 12.7%(14/110), and there was significant difference (P<0.05). Conclusions In chronic congestive heart failure patients undergoing coronary interventional therapy, the iso-osmolar contrast iodixanol is associated with a lower incidence of CIN compared with low-osmolar iohexol.

The serous papillary cystadenoma of low malignant potential in the paratesticular tissue is a tumor characterized by its resemblance to ovarian serous papillary tumor of low malignant potential. Several possible origins have been proposed but it is thought to originate from the Mullerian-type epithelium just like ovarian serous tumor of low grade malignancy. Because of the rarity of this tumor, the natural history and treatment have not been established. Herein we report on a serous papillary cystadenoma arising in the paratesticular tissue of a 12 year old . To our knowledge, this is the first reported case in the Korean literature. The size of this cystic tumor in this patient was 0.9x0.9x0.8 cm and had a sponge-like cut surface. The papillary structure was lined by both ciliated and nonciliated secretory cells, the same cellular structure as the salpinx. Areas with just a few mitoses and stratification of epithelial cells were noted, but invasion into the paratesticular tissue was absent, suggesting borderline malignancy. He is doing well after 5 months follow up. Prognosis of this scrotal tumor is thought to be better than the ovarian tumor of similar histology due to a better possibility of early detection.

Objective To observe the effect and safety of low dose milrinone used in patients suffering from refractory heart failure and renal dysfunction. Methods Forty-two patients with refractory heart failure and renal dysfunction were divided into treatment group(21 cases ) and control group(21 cases )by random digits table. All the patients accepted a therapy of cardiac booster, diuretics and vasodilators, and treatment group also accepted the therapy of milrinone [0.375 μ g/( kg· min), 10 mg/d, for 7 days]. And then the symptom, signs, blood pressure, heart rate, heart function and renal function before and after the treatment were observed. Results The total effective rate in treatment group was 85.7%( 18/21 ) ,significantly higher than that in control group [57.1% (12/21)] (P ＜0.05＝. After treatment,the heart rate,systolic blood pressure,diastolic blood pressure,stroke volume,cardiac output and left ventricular ejection fraction in treatment group and control group improved significantly than those before treatment, and these index improved better in treatment group [(79.3 ± 12.4) beats/min vs. (85.4 ± 10.2) beats/min, ( 107.6 ± 15.4)mm Hg ( 1 mm Hg = 0.133 kPa) vs.( 119.1 ± 13.5 ) mm Hg, (60.8 ± 9.4) mm Hg vs. (65.8 ± 8.5 ) mm Hg,(66.3 ± 10.2 ) ml vs. (61.2 ± 9.3 ) ml, (5.3 ± 0.6 ) L/min vs. (4.8 ± 0.9) L/min, (56.6 ± 8.4 )% vs. (48.9 ±7.3)% ,P ＜ 0.05＝. In two groups,there were no statistical difference in renal function. Conclusions Low dose of milrinone can improve the heart function of the patients with refractory heart failure and renal dysfunction and has good renal safety.

Melanoacanthoma is an extremely rare pigmented benign mixed epithelial tumor of both melanocytes and keratinocytes. A 52-year-old female presented an asymptomatic, slightly elevated, 1. 2 cm x 0. 8 cm, dark black-colored plaque on her right buttock of 2 years' duration. Histopathologic finding of the plaque shows hyperkeratosis, focal parakeratosis, follicular plugging, acanthosih, papillomatosis and pseudo-horn cyst in the epidermis. The tumor is composed of basaloid and squarnous cells with many foci of clusters and whorls of melanin pigment-laden cells. Electron microscopic finding reveals many scattered melanocytes in the entire epidermis. Melanin granules are found mostly in the melanocytes but can also be found in a few keratinocytes.

BACKGROUND: This study was performed to evaluate our experience on laparoscopic appendectomy. METHODS: Retrospective analysis was performed on 2,856 patients who had been operated by laparoscopic appendectomy under diagnosis of acute appendicitis at the Sung-Ae Hospital and Kwang-Myoung Sung-Ae Hospital from October 1991 to July 1998. RESULTS: Among 2,856 patients who had undergone laparoscopic appendectomy,2,379 patients (83.3%) were operated due to simple acute appendicitis, 275 patients (9.6%) due to perforated appendicitis. Operation time was 44.6 minutes for simple acute appendicitis and 60.3 minutes for perforated appendicitis. In perforated appendicitis, intra-peritoneal irrigation and drain insertion was performed. The length of hospital stay in patient with simple acute appendicitis was 3.7 days (5.82 days in conventional appendectomy) and patients with perfotrated appendicitis was 6.1 days (9.91 days in conventional appen-dectomy). Complications such as wound infection, intra-abdomen abscess, trocar site bleeding, subcutaneous emphysema developed in 43 (1.5%) patients (79/1,947, 4.5% in conventional appendectomy). In 202 (7.1%) patients, appendix was normal, but another diseases were detected, including acute pelvic inflammation, ovarian cyst, mesenteric lymphadenitis, enteritis, diverticulitis in order. CONCLUSION: Overall complication rate was lower in laparoscopic appendectomy compared with conventional appendectomy and the length of hospitalization of laparoscopic appendectomy was shorter. When the acute appendicitis is suspected, especially in the reproductive women, the laparoscopic approach would be better diagnostic and therapeutic value than conventional method. Therefore laparoscopic appendectomy would be replaced with conventional appendectomy.

Hailey-Hailey disease(benign familial chronic pemphigus) is a rare autosomal dominant disorder characterized by blisters at sites of friction such as the neck, axillae and groin which are caused by suprabasal epidermal acantholysis. We report two cases of Hailey-Hailey disease in the one family. One of the two cases has asymptomatic multiple longitudinal white bands in the fingernails associated with typical skin lesions. The nail lesions have not been described until reported by Burge in 1992 and it may be a characteristic finding in Hailey-Hailey disease.

The monoclonal antibody Ki-1(CD30) was first described in 1982 and was reported to react selectively with Reed-Sternberg cells in Hodgkins disease, highly activated B and T cells and large cell lymphomas of both T-and B-cell origin. Lymphomatoid papulosis(LyP) is characterized by recurrent erythematous papules or nodules that undergo spontaneous healing with hyperpigmentation and scarring. Histologically, two major types of LyP can be distinguished: type A is characterized by the presence of variable numbers of Ki-1+ large, atypical lymphocytes with some Reed-Sternberg like cells and type B is characterized by Ki-1- atypical cerebriform mononuclear cells similar to those in mycosis fungoides. We report a case of Ki-1+ lymphomatoid papulosis which was histopathologically recognized as a type B lesion but represented a Ki-1 positive reaction.
