The purpose of this study was to determine the quality of sperm and to evaluate the value of early referral to reproductive specialists for sperm banking in young men with cancer. Data was included in cancer patients who underwent sperm cryopreservation for fertility preservation at the university hospital from April 1998 to October 2011. Secondary analysis of prospective database was performed to evaluate the sperm quality in cancer patients. Of the 51 patients with 92 freezing cycles, data was available in 45 patients with 85 cycles (mean age 27.1±7.3). Thirty three patients were referred before chemotherapy (PreCTX) and 12 were after chemotherapy (PostCTX). Of the 85 cycles, 95.3% (volume), 77.6% (motility), and 44.7% (count) were lower than the normal values for semen analysis. In the PreCTX, 14 had single sperm collection (SSC) and 14 had multiple collections (MSC). There was significant difference in the mean-time of referral in the SSC vs MSC (3.2±3.6 vs 21.2±26.0, p=0.02), Five out of 33 in the PreCTX had additional sperm collection after chemotherapy due to the lack of sperm quality and quantity. Three out of those were referred on the first day of chemotherapy. Patients who were referred 5 days before chemotherapy enable multiple collections. Early referral for sperm banking before chemotherapy should be considered as an essential factor for fertility preservation since the quality of sperm in cancer patients tends to be lower than normal patients, when appropriate, enables multiple fertility preservation cycles. This is the first study demonstrating the benefit of early referral for sperm banking in cancer patients.

In this study, we evaluated the effects of dietary fiber extracted from Algelica keiskei Koidz on the chemical composition, cooking characteristics, and sensory properties of chicken patties. The chicken patties with Algelica keiskei Koidz dietary fiber had significantly higher moisture and ash content, and yellowness than the control sample (p<0.05). Energy value, cooking loss, reduction in diameter, reduction in thickness, lightness, redness, hardness, cohesiveness, gumminess, and chewiness of the control samples was significantly higher than chicken patties with Algelica keiskei Koidz dietary fiber (p<0.05). The sensory evaluation indicated that the greatest overall acceptability in chicken patties was achieved at Algelica keiskei Koidz dietary fiber levels of 1% and 2%. Chicken patties supplemented with 2% Algelica keiskei Koidz dietary fiber had improved quality characteristics.

The effects of sea tangle, sea mustard, hijiki, and glasswort were investigated based on the proximate composition, salinity, cooking loss, emulsion stability, pH, color, texture profile analysis, apparent viscosity, and sensory characteristics of reduced-salt (NaCl) meat batter and frankfurters. The moisture content, salinity, lightness of the meat batter and frankfurter, hardness, gumminess, and chewiness of the reduced-salt frankfurters with sea weeds were lower than the control without seaweed (p<0.05). The protein content, springiness, and cohesiveness of the reduced-salt frankfurters were not significantly different among the treatments (p>0.05). The moisture content, salinity, cooking loss, lightness, redness, hardness, gumminess, and chewiness of treatments with sea tangle and with sea mustard were lower than the control (p<0.05). Among the sensory traits, color was highest in the control (p<0.05). The flavor was also highest in the control. The treatments with sea tangle and with sea mustard samples had high tenderness, juiciness, and overall acceptability scores similar to the control (p<0.05). The results of this study show that the combination of low-salt and seaweed in the formulation successfully improved reduced-salt frankfurters, improving sensory characteristics to levels similar to the regular salt control (1.5%).

This study was aimed at comparing the pH, color, thiobarbituric acid (TBA), volatile basic nitrogen (VBN), textural properties, and sensory evaluations of chicken meat patties containing lotus (Nelumbo nucifera) leaf powder, and assessing their shelf-life at refrigeration temperature (4±1℃). In the refrigerated storage, the pH, lightness, yellowness, springiness values, and sensory properties scores of the control as well as all the treated samples decreased as the storage increased. The hardness, gumminess, chewiness, TBA, and VBN-values of control and all the samples treated with lotus leaf increased during refrigerated storage. At the end of the storage period (day 28), chicken patties containing lotus leaf powder had lower pH, redness, yellowness, TBA, VBN, hardness, gumminess, and chewiness values than those of control. The results of this study showed that a lotus leaf powder can increase storage stability in chicken meat products.

Objective: For short-duration surgery, propofol and remifentanil are the drugs of choice for intubation without neuromuscular blockade. The Shikani Optical Stylet (SOS) is a novel semi-rigid type fiberoptic laryngoscope. In this study, we determined the clinically required effect-site concentration of remifentanil for intubation using SOS without neuromuscular blockade depending on propofol effect-site concentration. Methods: We enrolled patients scheduled for elective surgery with general anesthesia, and assigned them into two groups by a randomized, double-blind method: concentration of propofol 3.5 μg/mL (group PRO 3.5) and 7.0 μg/mL (group PRO 7.0). Anesthesia was conducted with target-controlled infusion in predetermined target effect-site concentrations of propofol. The concentration of remifentanil for successful intubation using SOS in 50% of patients (EC50) was determined using a modified Dixon’s up-anddown method. Results: The mean±standard deviation EC50 of remifentanil was 5.07±0.40 ng/mL in group PRO 3.5 and 1.79±0.44 ng/mL in group PRO 7.0. From probit analysis, EC50 and EC95 of remifentanil in group PRO 3.5 were 4.85 ng/mL (95% confidence interval [CI], 4.44– 5.16 ng/mL) and 5.42 ng/mL (95% CI, 5.13–7.47 ng/mL) respectively, and EC50 and EC95 of remifentanil in group PRO 7.0 were 1.68 ng/mL (95% CI, 1.22–2.01 ng/mL) and 2.29 ng/mL (95% CI, 1.98–4.05 ng/mL), respectively. Conclusion: Increased concentration of propofol reduced EC50 of remifentanil for successful intubation using SOS without neuromuscular blockade.

Objective To investigate the effect of radial extracorporeal shock wave therapy (rESWT) on hemiplegic shoulder pain (HSP) syndrome.Methods In this monocentric, randomized, patient-assessor blinded, placebo-controlled trial, patients with HSP were randomly divided into the rESWT (n=17) and control (n=17) groups. Treatment was administered four times a week for 2 weeks. The visual analogue scale (VAS) score and Constant-Murley score (CS) were assessed before and after treatment, and at 2 and 4 weeks. The Modified Ashworth Scale and Fugl-Meyer Assessment scores and range of motion of the shoulder were also assessed.Results VAS scores improved post-intervention and at the 2-week and 4-week follow-up in the intervention group (p<0.05). Respective differences in VAS scores between baseline and post-intervention in the intervention and control groups were –1.69±1.90 and –0.45±0.79, respectively (p<0.05), between baseline and 2-week follow-up in the intervention and control groups were –1.60±1.74 and –0.34±0.70, respectively (p<0.05), and between baseline and 4-week follow-up in the intervention and control groups were –1.61±1.73 and –0.33±0.71, respectively (p<0.05). Baseline CS improved from 19.12±11.02 to 20.88±10.37 post-intervention and to 20.41±10.82 at the 2-week follow-up only in the intervention group (p<0.05).Conclusion rESWT consisting of eight sessions could be one of the effective and safe modalities for pain management in people with HSP. Further studies are needed to generalize and support these results in patients with HSP and a variety conditions, and to understand the mechanism of rESWT for treating HSP.

Henoch-Schönlein purpura (HSP) is an immunologically mediated systemic vasculitis of small blood vessels that primarily involves the skin, gastrointestinal tract, joints and kidneys. HSP is a common vasculitic syndrome in children who, in most cases, achieve complete recovery. Pulmonary hemorrhage is a very rare manifestation of HSP. The authors present a case of a 46-year-old male presenting with pulmonary hemorrhage and renal involvement and the diagnosis of HSP. The patient responded to prednisolone therapy.

( Sang Wan Chung ),( Jong Jin Yoo ),( Joon Woo Lee ),( You Jung Ha ),( Eun Ha Kang ),( Yeong Wook Song ),( Yun Jong Lee ) 대한류마티스학회 2016 대한류마티스학회지 Vol.23 No.2
Calcium pyrophosphate dihydrate deposition disease most commonly presents with acute arthritis of the peripheral joints. Infrequently, a mass effect of this disease can cause axial symptoms, such as spinal stenosis, radiculopathy, or myelopathy. Herein, we report on the first Korean case of acute arthritis in the lumbar facet joint due to calcium pyrophosphate dihydrate crystal deposition disease. A 73-year-old female presented with acute fever, severe lumbago, and knee arthralgia, 11 days after partial parathyroidectomy. Plain radiographs showed multiple chondrocalcinosis, while a bone scan, computed tomography, and magnetic resonance imaging showed right L5-S1 facet arthritis. In synovial fluid from the facet and knee joints, positively birefringent calcium pyrophosphate dihydrate crystals were observed under polarized light microscopy. Under the diagnosis of acute calcium pyrophosphate dihydrate crystal arthritis (formerly known as ‘pseudogout’) in the facet joint, an intra articular triamcinolone injection was administered, which resulted in dramatic improvement of the symptoms within 24 hours.

This study investigated the effect of added freeze-dried mulberry fruit juice (FDMJ) (1, 3 and 5%) on the antioxidant activity and fermented characteristic of yogurt during refrigerated storage. A decrease in pH of yogurt and increase in acidity was observed during fermentation. The yogurts with FDMJ exhibited faster rate of pH reduction than control. Initial lactic acid bacteria count of yogurt was 6.49-6.94 Log CFU/g and increased above 9 Log CFU/g in control and 1% in FDMJ yogurt for 24 h. The total polyphenol and anthocyanin content of FDMJ yogurt was higher than that of control due to the presence of phytochemical contents in mulberry. Moreover, antioxidant activity such as DPPH and reducing power was highest 5% FDMJ yogurt. During cold storage, pH decreased or remained constant in all yogurts with values ranging from 4.08 to 4.78 units. In sensory evaluation, the score of 1% FDMJ yogurt was ranked higher when compared with other yogurts. It is proposed that mulberry fruit juice powder can be used to improve sensory evaluation and enhance functionality of yogurt.
