Rotator cuff tears are a common cause of debilitating pain, reduced shoulder function, and weakness. Despite improvements in the understanding of the disease process and advances in surgical treatment, recent studies have reported that healing of massive rotator cuff tears is not as predictable as that of smaller rotator cuff tears. These high failure rates are a result of both mechanical and biologic factors that may affect the patients' intrinsic capacity to heal. Most research studies have concentrated on tissue engineering as a means for improvement of healing in rotator cuff repair, including the use of scaffolds, growth factors, and mesenchymal stem cells. There has been much interest in the development of various scaffolds that provide adequate strength as well as stimulate and enhance healing potential. The purpose of this paper is to review the current basic science and clinical application of extracellular matrix scaffolds, which are currently the most widely used scaffolds for repair of rotator cuff tears.

An ultrasonographic examination revealed increased fetal bladder size and decreased AFI as well as fetal bilateral hydronephrosis at 173weeks' gestation. Diagnosis of the fetal posterior urethral valve syndrome was made. Percutaneous fetal bladder puncture with aspiration and amniocentesis was performed. The fetus was normal male karyotype and with a predicted good renal function(sodium concentration, chloride concentration, and osmolarity at 74 mEq/L, 60 mEq/L, and 148 mOsm, respectively). So, the fetus underwent amnioinfusion and vesico-amniotic shunting procedure (VASP) using a double-basket catheter at 194weeks' gestation in order to prevent development of dysplastic kidneys and hypoplastic lungs. The healthy male baby was delivered at 384weeks' gestation and had normally functioning kidney. Cutaneous vesicostomy was performed for the newborn since the urethral orifice was small. The one year old infant is now well and waiting for urethroscopic valve ablation procedure.

OBJECTIVE: To know whether HPV Oligonucleotide Microarray (HPVDNAChip) can detect the HPV DNA in the urine and, if it can, to compare the results with Pap smear, biopsy, and cervix HPVDNAChip. METHODS: The authors had done Pap smear, cervix HPVDNAChip and colposcopy-guided punch biopsy as well as detailed information to those who visited Dept. of Ob. And Gyn. during 1st of April to 31st of May in 2003 for their uterine cervical problems related to the neoplasia. When they were determined to admit for treatment, urine had been collected to be tested by HPVDNAChip. RESULTS: Among 25 patients enrolled in this study, there were 10 whose urine HPVDNAChip test turned out positive (40%). Among 10 positive results, 9 patients had HPV 16 subtypes. Among 10 urine HPVDNAChip positive patients, there were 5 HSIL, 4 squamous cell cancer (SCC), and 1 ASCUS cell types on the Pap smears. Among 15 urine HPVDNAChip negative patients, there were 7 HSIL, 5 SCC, 1 ASCUS, 1 LSIL, and 1 AGUS. Among 10 urine HPVDNAChip there are 5 CIN3, and 4 invasive SCC, and 1 adenocarcinoma at the biopsy. Among 15 urine HPVDNAChip negative patients, there are 7 CIN3, 6 invasive SCC, 1 adenocarcinoma in situ, and 1 CIN1 patient. Whenever there were a urine HPVDNAChip 16 subtype positive, there were always cervix HPVDNAChip 16 subtype positive, but among the 12 urine HPVDNAChip negative patients, 5 had HPV 16 subtype positive and 4 had another subtypes and 3 had negative on cervix HPVDNAChip tests. CONCLUSION: Using HPVDNAChip, we verified that 40% of patients had the HPV DNA in their urine who had admitted for the treatment of their cervical neoplasm. And HPV 16 subtype was the most common type in the urine. If we can extend this data more widely, we might use it as an auxiliary tool for cervical HPV infection.

PURPOSE: Despite significant improvements in surgery, anesthesia, and postoperative critical care, the postoperative mortality rate of ruptured abdominal aortic aneurysm (RAAA) has remained at 40% to 50% for several decades. Therefore, we evaluated factors associated with the postoperative mortality of RAAA. MATERIALS AND METHODS: From January 1999 to December 2008, a retrospective study was performed with 34 patients who underwent open repair of RAAA. The preoperative factors included age, sex, smoking, comorbidities, serum creatinine, hemoglobin, shock, pulse rate, and time from emergency room to operation room. The intraoperative factors included blood loss, transfusion, aortic clamping site and time, aneurysmal characteristics, rupture type, graft type, hourly urine output (HUO), and operative time. The postoperative factors included inotropic support, renal replacement therapy (RRT), reoperation, bowel ischemia, multiple organ failure (MOF), and intensive care unit stay. The 2-day and the 30-day mortality rates were analyzed separately. RESULTS: The 2-day and the 30-day mortality rates were 14.7% and 41.2%, respectively. On univariate analysis, shock, transfusion, HUO, inotropic support and MOF for the 2-day mortality and serum creatinine, transfusion, aortic clamping site, HUO, inotropic support, RRT and MOF for the 30-day mortality were statistically significant. On multivariate analysis, shock, inotropic support and MOF for the 2-day mortality and aortic clamping site, RRT and MOF for the 30-day mortality were statistically significant. CONCLUSION: To decrease the postoperative mortality rate of RAAA, prevention of massive hemorrhage and acute renal failure with infrarenal aortic clamping, as well as prompt operative control of bleeding and maintenance of systemic perfusion are important.

Cryptococcosis is a systemic fungal infection caused by Cryptococcus neoformans. This mycosis is best known for meningeal involvement, yet, this disease rarely can be limited to the lungs. The usual portal of entry is respiratory tract. The recently rising incidence of the disease can be attributable to wide use of steroid, immunosuppressive agents and advent of AIDS. We experienced one case of pulmonary cryptococcosis in healthy person, who was admitted to the our hospital because of cough. Cryptococcus neoformans was isolated in the sputum, and lung tissue obtained by CT guide needle aspiration biopsy. Clinical improvement was noted after 6weeks of medical therapy with fluconazole.

Immunoglobulin deficiency with increased IgM, as defined by World Health Organization classification of primary immunodeficiency, is characterized by normal or increased concentrations of serum IgM and, in some cases, IgD, but decreased or absent IgG, IgA, and IgE. Patients with these disorders have a high incidence of recurrent pyogenic infections, including otitis media, pneumonia, and septisemia. We recently experienced a case of immunoglobulin deficiency with increased IgM in a 25-year old man. He had been suffered from recurrent pyogenic infections-pneumonia, otitis media-since about 6 months of his age. He was admitted due to pneumonia, and Haemophilus influenza was isolated from the sputum culture. Also chest X-ray showed bronchiectasis. His serum immunoglobulin levels revealed increased concentration of IgM and decreased IgG and IgA. He was successfully treated with antibiotics, and now he is being followed-up. So we present this case with the review of literature.

PURPOSE: Tamsulosin 0.2 mg is used widely in Asian people, but the low dose has been studied less than tamsulosin 0.4 mg or other alpha blockers of standard dose. This study investigated the efficacy and safety of tamsulosin 0.2 mg by a meta-analysis and meta-regression. MATERIALS AND METHODS: We conducted a meta-analysis of efficacy of tamsulosin 0.2 mg using International Prostate Symptom Score (IPSS), maximal urinary flow rate (Qmax), post-voided residual volume (PVR), and quality of life (QoL). Safety was analyzed using adverse events. Relevant studies were searched using MEDLINE, EMBASE, and Cochrane library from January 1980 to June 2013. RESULTS: Ten studies were included with a total sample size of 1418 subjects [722 tamsulosin 0.2 mg group and 696 other alpha-blockers (terazosin, doxazosin, naftopidil, silodosin) group]. Study duration ranged from 4 to 24 weeks. The pooled overall standardized mean differences (SMD) in the mean change of IPSS from baseline for the tamsulosin group versus the control group was 0.02 [95% confidence interval (CI); -0.20, 0.25]. The pooled overall SMD in the mean change of QoL from baseline for the tamsulosin group versus the control group was 0.16 (95% CI; -0.16, 0.48). The regression analysis with the continuous variables (number of patients, study duration) revealed no significance in all outcomes as IPSS, QoL, and Qmax. CONCLUSION: This study clarifies that tamsulosin 0.2 mg has similar efficacy and fewer adverse events compared with other alpha-blockers as an initial treatment strategy for men with lower urinary tract symptoms.

PURPOSE: With current advances in surgical technique, the prognosis for elective open repair of abdominal aortic aneurysm (AAA) has improved, but the mortality rate for ruptured AAA remains high. The aim of this study was to define the risk factors of AAA rupture. METHODS: We performed a retrospective analysis of 169 AAA patients who underwent open surgical repair between March 2000 and October 2010. According to the rupture, the patients were divided into 2 groups: 'ruptured' (n=41), 'non-ruptured' (n=128). To define the risk factor of ruptured AAA, we compared following variables between the 2 groups: clinical co-morbidities (hypertension, diabetes mellitus, ischemic heart disease, malignancies), diameter (maximal diameter of AAA), location of rupture, gender, and previous abdominal surgery history. RESULTS: Mean patient-age was 68.4+/-4.4 years (range: 32 to 86 years); the majority of patients were males, 135 (79.8%). Mean diameter of AAA was 6.67+/-2.0 cm (range: 4 to 15 cm); 'non-ruptured': 6.3+/-1.6 cm, 'ruptured': 7.8+/-2.6 cm. The risk of AAA rupture was statistically significantly increased with increased diameter of the AAA (P=0.007). On multivariateanalysis, the only statistically significant risk factor for AAA rupture was diameter of AAA (P=0.004). CONCLUSION: The only significant risk factor for AAA rupture found in this study is the diameter of AAA. To minimize the rupture rate of the AAA patients, we will have to closely monitor the size of AAA diameter.

Asparagus cochinchinensis has been used to treat various diseases including fever, cough, kidney disease, breast cancer, inflammatory disease and brain disease, while IL-4 cytokine has been considered as key regulator on the skin homeostasis and the predisposition toward allergic skin inflammation. However, few studies have investigated its effects and IL-4 correlation on skin inflammation to date. To quantitatively evaluate the suppressive effects of ethyl acetate extracts of A. cochinchinensis (EaEAC) on phthalic anhydride (PA)-induced skin inflammation and investigate the role of IL-4 during their action mechanism, alterations in general phenotype biomarkers and luciferase-derived signals were measured in IL-4/Luc/CNS-1 transgenic (Tg) mice with PA-induced skin inflammation after treatment with EaEAC for 2 weeks. Key phenotype markers including lymph node weight, immunoglobulin E (IgE) concentration, epidermis thickness and number of infiltrated mast cells were significantly decreased in the PA+EaEAC treated group compared with the PA+Vehicle treated group. In addition, expression of IL-1β and TNF-α was also decreased in the PA+EaEAC cotreated group, compared to PA+Vehicle treated group. Furthermore, a significant decrease in the luciferase signal derived from IL-4 promoter was detected in the abdominal region, submandibular lymph node and mesenteric lymph node of the PA+EaEAC treated group, compared to PA+Vehicle treated group. Taken together, these results suggest that EaEAC treatment could successfully improve PA-induced skin inflammation of IL-4/Luc/CNS-1 Tg mice, and that IL-4 cytokine plays a key role in the therapeutic process of EaEAC.

The inhibitory effects of Asparagus cochinchinensis against inflammatory response induced by lipopolysaccharide (LPS), substance P and phthalic anhydride (PA) treatment were recently reported for some cell lines and animal models. To evaluate the hepatotoxicity and nephrotoxicity of A. cochinchinensis toward the livers and kidneys of ICR mice, alterations in related markers including body weight, organ weight, urine composition, liver pathology and kidney pathology were analyzed in male and female ICR mice after oral administration of 150, 300 and 600 mg/kg body weight/day saponin-enriched extract of A. cochinchinensis (SEAC) for 14 days. The saponin, total flavonoid and total phenol levels were found to be 57.2, 88.5 and 102.1 mg/g in SEAC, respectively, and the scavenging activity of SEAC gradually increased in a dose-dependent manner. Moreover, body and organ weight, clinical phenotypes, urine parameters and mice mortality did not differ between the vehicle and SEAC treated group. Furthermore, no significant alterations were measured in alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN) and the serum creatinine (Cr) in the SEAC treated group relative to the vehicle treated group. Moreover, the specific pathological features induced by most toxic compounds were not observed upon liver and kidney histological analysis. Overall, the results of the present study suggest that SEAC does not induce any specific toxicity in the livers and kidneys of male and female ICR mice at doses of 600 mg/kg body weight/day.
