Comparison of Isokinetic Strength between Stage 1,2 Impingement Syndrome and Rotator Cuff Tear

PURPOSE: The goal of this study was to evaluate differences in strength deficits between (i) patients with stage 1 or 2 impingement syndrome and (ii) patients with rotator cuff tears. MATERIALS AND METHODS: We enrolled 43 patients with stage 1 or 2 impingement syndrome (group 1) and 21 patients with rotator cuff tears (group 2). The isokinetic strength of both groups was evaluated at 60degrees/sec for external rotation, internal rotation, adduction and abduction. We measured the peak torque, total work, average power of bilateral sides, peak torque relationship to body weight, and the ratio between unilateral agonist and antagonist. RESULTS: The isokinetic strength deficits assessed in ratio of peak torque to body weight for group 1 and group 2 respectively were; 28.48+/-23.76% and 29.12+/-32.81% for abduction (p=0.929), 7.20+/-13.98% and 18.94+/-19.52%; for adduction (p=0.021), 16.88+/-13.76% and 25.80+/-24.07%; for external rotation (p=0.221), and 14.1+/-25.67% and 29.02+/-35.06% for internal rotation (p=0.059). For average power and total work, group 2 showed a significantly greater deficit for adduction and internal rotation than group 1. CONCLUSION: Those with rotator cuff tears have more isokinetic muscle strength deficits than those with stage 1 or 2 impingement syndrome. Progression from stage 1 and 2 impingement syndrome to stage 3 may result in greatest changes in strength deficits for internal rotation and adduction.

Characteristics of dietary pattern and tissue mineral in premenstrual syndrome patients / 대한산부인과학회지

About 80% of premenopausal women experience premenstrual syndrome (PMS), but the definite etiology or effective treatment is still under the investigation. In this study, serum and tissue mineral analysis, which are essential for biosynthesis and secretory regulation of neurotransmitters, We evaluate what kind of changes in mineral levels is correlated to the presence of PMS. This study also include the approaches that entail changes to diet and lifestyle so that symptoms of premenstrual disorders can be alleviated. 61 women who were recruited on volunteer basis and completed Modified Moss Menstrual Distress Questionnaire (MMDQ) and devided into 2 groups, scored less than 10 points, as control group, and women scored higher than 11 points, as PMS group. They were asked to fill out questionnaires about their diet patterns and submitted to tissue mineral and serum analysis to evaluate the levels of Ca, Mg, Na, K, Cu, and Zn. In the control group, serum Mg and Zn were relatively high but within normal reference range, but showed high level of Mg and Zn in tissue. For Mini Dietary Assessment Index (MDAI), the score of control group was 33.8 and that of PMS group 19.7, showed statistical significance (P<0.05). The score of daily calcium-taking group was 21.6+/-3.7 whereas that of seldom calcium-taking group was 39.6+/-6.2 (P<0.05). The score of daily magnesium-taking group was 9.75+/-2.7 whereas that of seldom magnesium-taking group was 26.0+/-4.9 (P<0.05). In this study, we conclude the importance of dietary and lifestyle modifications could prevent and treat symptoms of PMS and minerals had significant roles of regulating PMS especially Ca, Mg and Zn. Further studies about roles of these minerals and possible therapeutic applications using minerals in PMS are needed.

The effects of the number of normal vaginal deliveries to the function of low urogenital system / 대한산부인과학회지

OBJECTIVE: The purpose of this study was to evaluate if the number of normal vaginal deliveries influences lower urogenital system function and the incidence of incontinence. MATERIALS AND METHODS: The POP-Q (Pelvic Organ Prolapse Quantitation) examination was performed in 217 premenopausal women who visited our hospital for routine check up. They were asked to fill in the Bristol female lower urinary tract symptom (BFLUTS) and self-report questionnaire for fecal incontinence and constipation assessment questionnaires. Exclusion criteria included patients with a history of pelvic surgery, BMI >25, chronic lung disease, cardiovascular disease, colon disease or smoking. RESULTS: There was a significant difference between the vaginal delivery group and none vaginal delivery group in the point Aa, Ba, Ap, Bp and Tvl in POP-Q (P<0.05). The patients were classified into four groups (0, 1, 2,above 3) according to the number of vaginal deliveries, and the incidences of fecal incontinence were 4%, 29%, 32%, 26% in each group, respectively. The incidence of fecal incontinence was significantly lower (P<0.05) in those who did not deliver vaginally, while no difference was observed in the number of vaginal deliveries. The BFLUTS-IS (incontinence symptom) score was higher in the patients with higher number of vaginal deliveries (P<0.05). There were also more patients with sexual dysfunction as was shown by the BFLUTS-sex questionnaire (P<0.05) in those patients with higher number of vaginal deliveries. CONCLUSION: We observed that the number of vaginal delivery is significantly associated with the incidence of fecal and urinary incontinence, and also that it was a major cause of disorders of the pelvic floor and sexual dysfunction.

Initial Dose Cascade of TTS Fentanyl with Proper Adjuvant Medications in Cancer Pain

According to the three step-ladder analgesics in patients with cancer pain, adjuvant drugs are required for pain relief according to the pain character and also to reduce side effects of opioids. Pain clinicians sometimes want to decide to jump directly from naive and mild opioid to transdermal therapeutic system (TTS) fentanyl with less side effects. We investigated the safety, efficacy, and satisfaction of the patients of TTS fentanyl converting from opioid-naive and mild-opioid with adjuvant drug medications in related to dose cascade of TTS fentanyl. Both opioid-naive (n=3) and opioid-using (n=34) patients started with TTS fentanyl in the lowest available delivery rate (25 microgram/hr) with rescue medication. A numeric rating scale (NRS, from 0=no pain to 10=worst pain imaginable), satisfaction of the patients with the transdermal therapy and side effects were recorded everyday during 29 days. Average reductions of NRS scores were 1.79 and 2.77, and the mean doses were 35.14 and 44.12 microgram/hr on the 15th and 29th day, respectively. Reported level of satisfaction with the transdermal patch and generalized pain management were 'completely satisfied' and 'satisfied'. Frequent side effects were nausea, vomiting, and constipation. In conclusion, initial application of TTS fentanyl with proper adjuvant medications is effective, safe, and well tolerated.

The comparison of microleakage on intracoronal restoration after non-vital bleaching / 대한치과보존학회지

The purpose of the present study were to evaluate microleakage of a fourth generation dentin-bonding agent following a walking bleaching treatment, to determine the effect of temporary postbleaching dressing with calcium hydroxide on microleakage and to investigate the effect of delayed intracoronal restoration on microleakage. The results of this study were as follows: 1. Bleached groups showed more microleakage than unbleached group. 2. Immediately restored group following bleaching procedure showed the highest microleakage score. 3. One-week delayed restorations showed less microleakage but there were no statistically significant difference between group II and III. 4. Provisional dressing with calcium hydroxide had no influence on microleakage. It is necessary to know the time that has elapsed from the bleaching treatment to the restoration procedure to achieve optimal seal, as well as to reduce the risk of microleakage in adhesive restoration.

Adenovirus and Lipofectin Mediated p53 Gene Transfection Efficiency in Human Cervical Cancer Cell Lines and Xenografted Nude Mouse / 대한산부인과학회잡지

BACKGROUND: The classical treatment of the cervical cancer is surgery, radiotherapy, chemotherapy. Even though the improvement of treatment successful rate, conventional therapy has some limitations. Recent cutting edge of cancer therapy has been developed in gene level including understand the biological characteristics of the cancer cells, enhance the human immune response, suppress the cancer cell proliferation. Therefore, the gene therapy is proposed to new treatment strategy. PURPOSE: The transfection efficiency of cervical cancer cell lines and cervical cancer cell line xerografted nude mouse was investigated by transfection of liposome and infection of adenovirus mediated suppressor(p53) and reportor(LacZ) gene. METHOD: The cervical cancer cell lines was used in this study were CaSki, SiHa (HPV16 positive, wild type p53 gene), HeLa, HelaS3(HPV18 positive, wild type p53 gene) and C33A, HT3(HPV negative, mutant p53). Direct plasmide and AdCMVp53 gene transfection was performed by using liposome system (pRcCMVLacZ / lipofectin, FuGene 6, Ca-phosphate). LacZ gene was used as the reportor gene for the transfection efficiency evaluation. Expression of p53 in cell lines and tumor tissue was confirmed by western blot and immunohistochemical staining. Xenografted nude mouse of SiHa cell line was infected by AdCMVp53 and AdCMVLacZ. Transfection efficiency was observed by same as above. RESULTS: In cervical cancer cell lines, gene transfection using liposome system(pRcCMVLacZ/lipofectin, FuGene 6, Ca-phosphate)revealed different transfection efficiency, especially pRcCMVLacZ in Fugene 6 showed 18-40% of high transfection efficiency in 6 cervical cancer cell lines by X-gal staining and AdCMVp53 showed 95-98% of the high transfection efficiency in HeLa, C33A. AdCMVp53 was significantly expressed at 2-5days after injection xenografted nude mouse on the western blot and transfection efficiency was 19.79+/-5.36, 26.26+/-11.69, 14.77+/-3.98,15.99+/-6.43%(day1-5). AdCMVLacZ were found to immuno- histochemistry analysis, in vivo transfection efficiency was 61.26+/-4.66,59.63+/-9.12, 29.46+/-14.33, 31.73+/- 22.64%(day 1-5) atx200 and 88.65+/-8.65, 70.85+/-20.94, 40.75+/-25.44, 48.21+/-10.97% (day 1-5) atx400. CONCLUSION: As a results, adenovirus-mediated transfection efficiency was higher in vivo experiment compared to cell lines. These high efficiency of adenovirus-mediated suppressor gene(p53) could become a significant meaningful data gene therapy strategy both transgenic mice and cervical cancer cell lines.
