Abstract
Abstract
Background: Both cosmetic and oncologic outcomes are becoming more important for breast cancer patients. Breast-conserving surgery (BCS) has an acceptable cosmetic result compared with mastectomy, but BCS is also associated with cosmetic failure. In this study, we evaluated the cosmetic outcome of reconstructive surgery with the absorbable implant vicryl mesh after BCS compared with the outcome of BCS alone.
Methods: From May 2007 to December 2009, 101 patients were involved in this study at Hallym University Sacred Heart Hospital. We used absorbable implants made of folding vicryl mesh and wrapped them with Interceed. In 79 cases, BCS with vicryl mesh implantation was performed; in the other 56 cases, only BCS was performed. Patient satisfaction with cosmetic outcomes was evaluated. We also analyzed other factors that affected cosmetic outcomes, including patient ages, body mass indices, tumor locations, and removed breast tissue.
Results: In the vicryl mesh implantation group, 65 of 79 patients (82.3%) were satisfied; in the BCS-only group, 24 of 56 patients (43%) were satisfied (P < 0.05). In the vicryl mesh implantation group, patient ages, body mass indices, and removed breast tissue did not affect cosmetic outcomes. When the tumor was located in the upper outer quadrant, the patients were more satisfied (P < 0.05). Conclusions: Reconstructive procedures with vicryl mesh are simple, safe, and less expensive than other plastic reconstruction techniques. This study suggests that the procedure was superior to BCS alone in cosmetic outcomes. We believe that the procedure could become a favorable technique in oncoplastic surgery.

Abstract
AIM To identify the presence, and origin, of any "dissociating factors" inherent to the techniques for evaluating progression that mask the relationship between structural and functional progression in open-angle glaucoma (OAG). METHODS 23 patients (14 with OAG and 9 with ocular hypertension (OHT)) who had received serial Heidelberg Retina Tomograph (HRT II) and Humphrey Field Analyser (HFA) examinations for >or=5 years (mean 78.4 months (SD 9.5), range 60-101 months) were identified. Evidence of progressive disease was retrospectively evaluated in one eye of each patient using the Topographic Change Analysis (TCA) and Glaucoma Progression Analysis (GPA) for the HRT II and HFA, respectively. RESULTS Six patients were stable by both techniques; four exhibited both structural and functional progression; seven exhibited structural progression, only, and six showed functional progression, only. Three types of dissociating factors were identified. TCA failed to identify progressive structural damage in the presence of advanced optic nerve head damage. GPA failed to identify progressive functional damage at stimulus locations, with sensitivities exhibiting test-retest variability beyond the maximum stimulus luminance of the perimeter, and where a perimetric learning effect was apparent. CONCLUSION The three dissociating factors accounted for nine of the 13 patients who exhibited a lack of concordance between structural and functional progressive damage.

Efficacy of methylsulfonylmethane (MSM) in osteoarthritis pain of the knee: a pilot clinical trial. Osteoarthritis Cartilage 2006; 14:286-94. [PMID: 16309928 DOI: 10.1016/j.joca.2005.10.003] [Citation(s) in RCA: 90] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2005] [Accepted: 10/08/2005] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Osteoarthritis (OA) is the most common form of arthritis and the second most common cause of long-term disability among middle-aged and older adults in the United States. Methylsulfonylmethane (MSM) is a popular dietary supplement used as a single agent and in combination with other nutrients, and purported to be beneficial for arthritis. However, there is paucity of evidence to support the use of MSM. METHODS A randomized, double-blind, placebo-controlled trial was conducted. Fifty men and women, 40-76 years of age with knee OA pain were enrolled in an outpatient medical center. Intervention was MSM 3g or placebo twice a day for 12 weeks (6g/day total). Outcomes included the Western Ontario and McMaster University Osteoarthritis Index visual analogue scale (WOMAC), patient and physician global assessments (disease status, response to therapy), and SF-36 (overall health-related quality of life). RESULTS Compared to placebo, MSM produced significant decreases in WOMAC pain and physical function impairment (P<0.05). No notable changes were found in WOMAC stiffness and aggregated total symptoms scores. MSM also produced improvement in performing activities of daily living when compared to placebo on the SF-36 evaluation (P<0.05). CONCLUSION MSM (3g twice a day) improved symptoms of pain and physical function during the short intervention without major adverse events. The benefits and safety of MSM in managing OA and long-term use cannot be confirmed from this pilot trial, but its potential clinical application is examined. Underlying mechanisms of action and need for further investigation of MSM are discussed.

Abstract
One of the major targets for breast cancer therapy is the epidermal growth factor receptor (EGFR) and related receptors, which signal via different signal transduction pathways including the mitogen-activated protein kinase (MAPK) pathway. This study determined whether there is a correlation between EGFR/HER2 status and MAPK (ERK1/2) phosphorylation in breast cancer cells, and how this affects the response to an inhibitor of the receptors. Expression of EGFR, HER2 and phosphorylated ERK1/2 were measured by immunoblotting in a panel of breast cancer cell lines. Several lines expressed high levels of pERK1/2, with no obvious correlation with the level of EGFR/HER2. The EGFR tyrosine kinase inhibitor PKI166 inhibited growth and induced apoptosis in some cells with high levels of growth factor receptors (MDA-MB-468, SUM149, SKBR3), but was less effective in cells that also had high basal ERK1/2 activity (MDA-MB-231). The combination of an inhibitor of MAPK signalling (U0126) and PKI166 produced significantly more inhibition and apoptosis than either agent alone. This suggests that constitutive activation of the MAPK pathway may bypass inhibition of EGFR/HER2 tyrosine kinases, and lead to insensitivity to agents targeting the receptors. However, inhibiting both EGFR/HER2 and MAPK signalling can result in significant growth inhibition and apoptosis of EGFR-expressing breast cancer cells.

Abstract
A lab-scale upflow anaerobic bioreactor filled with granular sludge and cow manure was operated for 140 days to determine the mechanism of metal removal and the vertical distribution of metal precipitates. Heavy metal ions were removed in the order of Cu2+, Cd2+, Zn2+, Fe2+ and Mn2+ with respect to the height in the reactor. The solid phase analysis showed that the heavy metals were mostly precipitated in the form of metal sulfides by sulfate reduction The contents of metal precipitates in the reactor were as follows: (i) Cd and Zn were highest in the bottom, (ii) Fe was highest at the low-middle layer, and (iii) Mn was increased with the height in the reactor. The vertical distribution of metal sulfides in the reactor was directly related to the solubility product (Ksp). Results obtained in this study suggest a feasibility of the application to separate precipitation metal-containing wastewater.

Abstract
OBJECTIVE To report the cytologic findings of mucocelelike tumor and mucinous carcinoma. STUDY DESIGN All mucinous neoplasms diagnosed by fine needle aspiration and confirmed by histologic examination were reviewed to detect the cytologic findings helpful for the differentiation. The cytologic findings were correlated with the histologic findings. RESULTS Cytologically, mucinous carcinomas were highly cellular and showed many single epithelial cells and variably formed epithelial cell clusters in abundant extracellular mucin. Malignant cells exhibited round, atypical nuclei; granular chromatin; and small nucleoli. Mucocele like tumor showed low cellularity with scanty, monolayered, small sheets of epithelial cells and abundant, extracellular mucin. Myoepithelial cells were present within the epithelial cell sheets. Tumor cells were usually small, with uniform, round nuclei; fine chromatin; and absence of nucleoli. CONCLUSION Cytologic findings of mucocelelike tumor and mucinous carcinoma were different in cellularity, shape of cell clusters and nuclear features, although mucocelelike tumors having a carcinoma component were similar to mucinous carcinoma. Awareness of the cytologic findings of breast mucinous neoplasms is important to make a specific diagnosis.

Abstract
BACKGROUND Physical discomfort, anxiety, embarrassment, and other aspects of patient experience impact on future compliance for colonic imaging tests. Therefore, a prospective study was performed comparing patient experiences during air contrast barium enema (ACBE), flexible sigmoidoscopy, and colonoscopy. METHODS Immediately after each procedure, patients completed a questionnaire assessing pretest anxiety, difficulty with preparation, pain, cramping, bloating, overall discomfort, loss of dignity, willingness to repeat the test, and overall satisfaction. A follow-up questionnaire was administered within 48 hours. Nurses and physicians also completed questionnaires to assess the provider impression of patient experience. RESULTS Four hundred ten patients (80 ACBE, 202 sigmoidoscopy, 128 colonoscopy) were prospectively enrolled. Sigmoidoscopy caused more pain than ACBE (Odds ratio [OR] 2.64: 95% CI [1.63, 4.27]) or colonoscopy (OR 1.83: 95% CI [1.21, 2.77]). ACBE and colonoscopy did not differ in the degree of pain. Although overall satisfaction appeared to be similar for all tests, patients were less willing to repeat ACBE than sigmoidoscopy (OR 1.85: 95% CI [1.13, 3.02]) or colonoscopy (OR 1.82: 95% CI [1.07, 3.09]). Initial and follow-up pain ratings by patients were highly correlated (Spearman correlation 0.81); however, correlation of pain assessments between staff and patients was poor (Spearman correlation 0.48). CONCLUSIONS Sigmoidoscopy was more painful than other colonic imaging modalities. Although ACBE and colonoscopy caused similar pain, patients were less willing to repeat ACBE. In aggregate, the data suggest that patients perceive colonoscopy as the most acceptable colonic imaging procedure. Better methods are required to allow staff to adequately assess discomfort experienced by patients during these procedures.

Abstract
Antibody responses in serum and cerebrospinal fluid (CSF) samples from patients with active and chronic paragonimiasis and in sera from patients on whom follow-up studies were done after praziquantel treatment were analyzed using antigens of Paragonimus westermani prepared from eggs, metacercariae, juveniles of 4- and 7-week old, adult worms and recombinant protein of 28 kDa cruzipain-like cysteine protease (rPw28CCP). The patient sera/CSFs of active and chronic paragonimiasis revealed strong antibody reactions against the crude extracts of 4- and 7-week old juveniles as well as against those from egg and adult. rPw28CCP also showed specific reaction to the sera with active paragonimiasis. After the treatment, levels of specific antibodies in the sera gradually decreased to negative range in most patients. In some cases with persisting high antibody levels, however, the reactions at 27 kDa egg protein were sustained throughout the observation period of 34 months. The reactions at 35 and 32 kDa in adult extract and rPw28CCP disappeared rapidly after the treatment. Persistent antibody reactions even after successful treatment are provoked by continuous antigenic challenge from eggs which were not resolved by treatment.

Abstract
OBJECTIVES Endosonography is accurate for staging esophageal cancer. However, whether detailed staging impacts clinical decision making, whether endosonography is perceived as a useful modality, and what factors influence the utilization of endosonography have not been studied. METHODS One hundred gastroenterologists were surveyed about staging and management of esophageal cancer, including: 1) management by stage; 2) perceived usefulness of endosonography; 3) availability of endosonography; and 4) number of patients referred. RESULTS Clinical decisions varied by incremental differences in tumor stage. However, only 27 of 66 respondents (40.9%) judged endosonography to be very useful or essential for the evaluation of esophageal cancer and only 22 (33.3%) had referred a patient. Perceived usefulness and availability were independent factors strongly associated with referral for endosonography. Among 18 respondents to whom endosonography was available and who considered it useful, 14 (77.9%) had referred a case. In contrast, a conservative management was not associated with either perceived usefulness of or referral for endosonography. CONCLUSIONS Clinicians recognize the importance of detailed staging for management of esophageal cancer. Despite this, they underestimate the utility of endosonography and fail to refer patients for appropriate evaluation. Lack of perceived usefulness and unavailability are important independent barriers to utilization of endosonography in clinical practice.

Abstract
OBJECTIVE Potential transmission of cryptosporidiosis through drinking water supplies has been highly publicized; however, it is unknown whether this reporting has increased patient awareness or reduced other risk behaviors for exposure to this organism, such as high-risk sexual behavior. METHODS Consecutive patients presenting for initial evaluation to the Gastroenterology AIDS Clinic completed a questionnaire that assessed knowledge about cryptosporidiosis, perceived risk of infectious diarrhea, drinking water sources, and high-risk sexual behavior. RESULTS Fifty-one patients completed the questionnaire (82% male; 86% homosexual; mean age, 38 years; median CD4 count, 136 x 10(6) cells/L). Most respondents (31 of 44; 70%) believed they were at risk for infectious diarrhea. Awareness of cryptosporidiosis was high (31 of 45; 69%) as was avoidance of tap water (26 of 51; 51%) and exclusive or frequent use of bottled or boiled water (40 of 51; 78%). Respondents who used bottled water reported spending an average of $331.76 U.S. annually. However, high-risk sexual behavior remained common: 21 (41%) of the 51 subjects reported unprotected anal intercourse or oral-anal sexual contact. High-risk sexual behavior was prevalent even among subjects who drank exclusively boiled or bottled water. CONCLUSIONS Awareness of risk for infectious diarrhea and cryptosporidiosis is high among patients infected with HIV in San Francisco. Patients perceive drinking water to be a substantial risk factor for infectious diarrhea and incur significant expense to avoid tap water. However, high-risk sexual behaviors remain prevalent in this population and should be the focus of future education efforts.

Abstract
We have developed new, highly absorptive coatings for the vacuum UV wavelength range. These coatings display two distinct granularity scales: large structures of a 10-100-microm scale form efficient light traps, upon which are superimposed structures of a submicrometer scale. We present results for the total hemispherical reflectivity at normal incidence for 121.6 nm and at a grazing angle incidence for 17.1, 30.4, 58.4, and 121.6 nm. These measurements were made for the new coatings as well as for various coatings in common use. Absorption of the new coatings is in some cases higher than for the best-known coatings and, in contrast to the latter, they are mechanically robust.

Abstract
Diagnosis of early paragonimiasis is difficult because parasitological evidence is not easily obtained. Antibody tests have been proposed as a good substitute for classical diagnostic techniques. Using the crude extracts of Paragonimus westermani eggs, metacercariae, 4- and 7-week juveniles, and 16-week adults as antigens, we observed the early antibody responses. Sera were obtained from 4 experimental cats, fed 50 metacercariae each, at intervals until 13 weeks post-infection. Antibody (IgG) responses were identified by ELISA using extracts of 4-week juveniles, followed by those of 7- and 16-week worms. Antibody responses were minimal against the metacercarial extracts. Antibodies to P. westermani egg extracts were elevated after 10 weeks post-infection. In immunoblot analysis, more than nine protein bands in 4-week juveniles reacted with the early infection sera. Antigenic proteins in adult worms were different from those of juveniles. After four weeks of infection, 32 and 35 kDa bands in the adult extracts were increasingly reactive. Egg specific proteins at 28, 46 and 94 kDa were reactive only after 10 weeks. Antigenic components reacting to the early infection sera changed during the maturation stages of P. westermani; almost all juvenile antigens were replaced by adult antigen components.

Abstract
This paper examined the stress moderator and mediator effects of four dimensions of perceived control in children of divorce. The dimensions of locus of control included internal control for positive events, internal control for negative events, unknown control for positive events, and unknown control for negative events. The sample consisted of 222 children between the ages of 8 and 12 whose parents had divorced in the previous 2 years. Moderational analyses showed that unknown control for positive events interacted with negative events to predict total symptoms. Plots of the simple slopes indicated a stress buffering effect whereby the slope of negative events on symptoms was higher for high than for low levels of unknown control for positive events. Mediational analysis showed that the relations between negative events and symptoms were mediated by both unknown control for positive events and unknown control for negative events. In contrast, evidence was not found for either a stress mediational or a moderational model for perceived internal control for positive or negative events. These results suggest that unknown control beliefs may be a particularly important dimension of control for children of divorce.

Abstract
Observation of pigment deposition on the posterior lens central to Wieger's ligament and the position of the so-called Scheie line is reported as a clinical sign of the pigment dispersion syndrome (PDS). Although abnormal pigmentation of the posterior lens surface is well-known to occur as scattered deposition among the zonule insertions as well as in the shape of a line formed within the crevice just anterior to the junction between the posterior capsule and the anterior hyaloid face, pigmentation has not been well-known to occur more centrally, nearer the polar capsular region. Pigment in this location is a relatively unknown finding in PDS and may lead to suspicion and diagnosis of this disorder.

Abstract
PURPOSE This study was designed to determine and compare the intra- and interobserver variability of visual and computerized assessment of peripheral arterial disease (PAD) severity from lower extremity angiograms, and to correlate quantitative angiographic measures with clinical predictors of PAD. PATIENTS AND METHODS Peripheral angiograms of 13 segments from the ilio-femoral-popliteal system were evaluated on two separate occasions by nine radiologists and with a quantitative computerized method. In a separate study, images from 18 patients undergoing diagnostic lower extremity angiography were analyzed with use of quantitative angiography and the results were compared with clinical and lipid risk factors. RESULTS The data demonstrate that computerized assessment of peripheral angiograms is associated with lower intra- and interobserver variability than visual assessment of the same films. Despite this, there was excellent intraobserver and good interobserver agreement on the presence or absence of a severe lesion with visual assessment. Quantitative computerized measures of disease severity correlate with several known predictors of large vessel PAD. CONCLUSION Computerized assessment of peripheral angiograms may be a useful tool in the clinical and investigational evaluation of PAD.

Abstract
This is the first investigation of the psychiatric diagnosis of Asian American adolescents using data from the Los Angeles County Department of Mental Health. It was hypothesized that Asian American adolescents receive different diagnoses than Caucasian adolescents, and furthermore, that there are intra-Asian differences in diagnosis among the Asian subgroups. Asian American adolescents were categorized in the following subgroups: Chinese, Japanese, Korean, Filipino, Vietnamese, and other Asians (i.e., Southeast Asians and Pacific Islanders). Separate comparisons were made for male and female adolescents. The findings strongly support the presence of ethnic differences between Asian and Caucasian adolescents and also among Asian subgroups in both male and female groups. In the Asian-Caucasian comparison, Asian males and females received significantly more nonpsychiatric diagnosis than Caucasians. Asian males were more often diagnosed with nonpsychiatric disorder and less often with affective disorders than Caucasian males. Asian females were more frequently diagnosed with major depression and nonpsychiatric disorder than Caucasian females. Among Asian American adolescents, Chinese and Japanese adolescents received similar diagnoses while Korean and Vietnamese also showed similar patterns in diagnosis. The implications of intra-Asian differences are discussed.

Abstract
In order to clarify the role of the primary auditory cortex (AI) on middle latency responses (MLRs), we recorded the auditory evoked potentials (AEPs) from the vertex and the right and left AI areas of the skull simultaneously before and after creating serial lesions of the AIs contralateral and ipsilateral to the stimulated ear in 7 awake cats. The auditory brainstem responses (ABRs) and MLRs recorded from the vertex in normal awake cats revealed the presence of peaks 1-8, NA and PA within the analysis time of 50 msec. After there were serial AI lesions, (1) all the peaks remained at nearly the same latencies, (2) the amplitude of the NA was decreased significantly, that of the PA was slightly decreased and those of peaks 6, 7 and 8 were variable, and (3) the difference between the effects of the first operation (contralateral AI) and the second operation (ipsilateral AI) was not statistically significant. These findings indicated that the main, prominent effect of bilateral AI lesions on MLRs in the awake cat is a significant decrease in the NA amplitude.

Abstract
Antigenic proteins of 36 and 29 kDa were localized in Spirometra mansoni plerocercoid (sparganum) immunohistochemically by avidin biotin complex (ABC) staining. When polyclonal antibodies such as BALB/c mouse serum immunized with crude saline extract of sparganum or confirmed sparganosis sera were reacted as primary antibodies, the positive chromogen (3-amino, 9-ethylcarbazole) reactions were recognized at syncytial tegument, tegumental cells, muscle and parenchymal cells and lining cells of excretory canals. A monoclonal antibody (MAb) which was reacting to 36 and 29 kDa proteins in the extract of the worm was localized at the syncytial tegument and tegumental cells. The present results suggested that the potent antigenic proteins of 36 and 29 kDa in sparganum were produced at the tegumental cells and transported to the syncytial tegument.

Abstract
A 31-year old salesman living in Seoul developed suddenly abdominal pain due to intestinal obstruction. Exploratory laparotomy exhibited segmental jejunal cellulitis caused by penetrating Anisakis larva. The patient had eaten raw fish. The typical history of intestinal anisakiasis was presented with a short review of Korean patients of anisakiasis.

Abstract
A centrifugal counter-current partition chromatograph has been developed and tested in order to simplify earlier counter-current chromatographic (CCC) procedures. It includes a helical coil rotor and a rotating face-seal. The rotor is designed to be adapted in an ordinary laboratory centrifuge for toroidal coil CCC. Twisting between the inlet and outlet tubing is avoided by using the rotating seal in the rotor. The seal is placed between the rotor, on which helical coils are mounted, and a newly designed centrifuge lid. This chromatographic rotor, rotating simply around its own axis, has simplified a previous CCC device in which a coil planet mechanism is used to avoid tube twisting whilst retaining the capability for chromatographic separations. Results for separations of nystatin, dinitrophenylamino acids and Poly I:C were comparable to those obtained by liquid chromatography and the previous CCC procedure.
