Cases of LM with the PP method were compared with a matched control group of LM with a 5 mm claw forceps. The operative time, tumor separation time, specimen removal time, amount of blood loss, requirement for blood transfusion and length of hospital stay were compared between groups.Results: The two groups were matched by age, body mass index, previous cesarean delivery, main fibroid size, and number and weight of fibroids. The tumor separation time was significantly shorter in the PP group than the claw forceps group (9.7 ± 3.1 minutes versus 17.1 ± 4.4 minutes, p < 0.001). The length of the operation, hospitalization time, specimen removal time, amount of blood loss, and requirement for blood transfusion were not significantly different between groups.Conclusion: A stainless steel centimeter probe has an advantage over a 5 mm claw forceps in pushing and pulling fibroids. Our findings indicate that the PP method was much more effective in excision of fibroids than a 5 mm claw grasper in LM.","PeriodicalId":10018,"journal":{"name":"Chang Gung medical journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40185734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbubbles can basically improve the sensitivity of conventional ultrasound imaging to the microcirculation. The resonance of microbubbles in response to an incident ultrasound pulse results in nonlinear harmonic emission that serves as the signature of microbubbles in microbubble-specific imaging. Inertial cavitation and destruction of microbubbles can produce a strong mechanical stress enhancing the permeability of the surrounding tissues, and can further increase the extravasation of drugs from the blood into the cytoplasm or interstitium. Stable cavitation by high-frequency ultrasound can also mildly increase tissue permeability without causing any damage even at a high acoustic pressure. Microbubbles can carry drugs, release them upon ultrasound-mediated microbubble destruction, and simultaneously enhance vascular permeability to increase drug deposition in tissues. Various targeting ligands can be conjugated to the surface of microbubbles to attain ligand-directed and site-specific accumulation for targeted imaging. In addition to current developments in microbubble technology, this review introduces our studies of the applications of microbubble- specific imaging, ultrasound-aided drug delivery, and targeted imaging. These applications are promising but may require further improvement for clinical use.","PeriodicalId":10018,"journal":{"name":"Chang Gung medical journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40185799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Severe neonatal hyperbilirubinemia (NH) carries a potential for permanent neurological impairment. The current study analyzed possible etiologies leading to NH.Methods: A retrospective cohort of neonates with total serum bilirubin (TSB) ≥ 20 mg/dL was surveyed from 1995 to 2007. Subjects with gestational ages < 34 weeks were excluded, leaving a total of 413 enrolled neonates.Results: The most common etiology in relation to marked NH was breast milk feeding (38.5%), followed by glucose-6-phospahate dehydrogenase (G6PD) deficiency (24.0%), ABO incompatibility (21.8%), extravascular hemorrhage (6.5%), Rh incompatibility (2.9%), bacterial infection (2.2%), hereditary spherocytosis (1.2%), dehydration (1.2%), diabetic mother (1.0%), polycythemia (0.7%), and gastrointestinal obstruction (0.7%). Other rare etiologies included Down syndrome, Chinese herb intake, asphyxia, galactosemia and congenital hypothyroidism. We did not identify any known cause in 63 neonates (15.3%). Neonates with more than one etiology tended to have higher TSB than subjects without a known etiology (p < 0.05). Anemia was more common in those with G6PD deficiency, blood group incompatibility, hereditary spherocytosis, and gastrointestinal obstruction. Neonates fed breast milk tended to have prolonged NH.Conclusion: This study depicts the clinical features of marked NH. Breast milk feeding, G6PD deficiency and ABO incompatibility are common etiologies in Taiwan. Prolonged NH is more common in neonates fed breast milk than those who were given formula.","PeriodicalId":10018,"journal":{"name":"Chang Gung medical journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40185732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim was to determine the length, width and depth of the bicipital groove and to find the incidence of a supratubercular ridge of Meyer in an Indian population.Methods: The study included 104 unpaired dry humeri (48 right side and 56 left) which belonged to the anatomy laboratory of our institution. The length, width and depth of the bicipital groove were measured with a digital vernier caliper. The data were tabulated as mean ± SD and statistically compared between the right and left sides.Results: The mean length, width and depth of the bicipital groove were 84.6 ± 10.9 mm, 8.5 ± 2.3 mm and 4.4 ± 1.8 mm, respectively, which corresponded to 27.8% of the total length, 32.2% of the transverse width and 17% of the anteroposterior widh of the humerus, respectively. There was no statistically significant difference in these parameters between the left and right sides (p > 0.05). A supratubercular ridge of Meyer was seen in 24 (23.1%) of the humeri.Conclusion: The study determined the morphometric parameters of the bicipital groove in an Indian population. We believe that this study will be an important reference for scientific research, and the details are also important for anthropologists and clinical anatomists.","PeriodicalId":10018,"journal":{"name":"Chang Gung medical journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40185733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The past decade has seen an explosion of methodological advances in molecular cytogenetics technology. These cytogenetics techniques add color to the black and white world of conventional banding. Fluorescence in-situ hybridization (FISH) study has emerged as an indispensable tool for both basic and clinical research, as well as diagnostics, in leukemia and cancers. FISH can be used to identify chromosomal abnormalities through fluorescent labeled DNA probes that target specific DNA sequences. Subsequently, FISH-based tests such as multicolor karyotyping, comparative genomic hybridization (CGH) and array CGH have been used in emerging clinical applications as they enable resolution of complex karyotypic aberrations and whole global scanning of genomic imbalances. More recently, crossspecies array CGH analysis has also been employed in cancer gene identification. The clinical impact of FISH is pivotal, especially in the diagnosis, prognosis and treatment decisions for hematological diseases, all of which facilitate the practice of personalized medicine. This review summarizes the methodology and current utilization of these FISH techniques in unraveling chromosomal changes and highlights how the field is moving away from conventional methods towards molecular cytogenetics approaches. In addition, the potential of the more recently developed FISH tests in contributing information to genetic abnormalities is illustrated.","PeriodicalId":10018,"journal":{"name":"Chang Gung medical journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40185796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Irreversible parenchymal damage will develop if a testicle is twisted. The aim of the study was to determine the importance of different clinical clues to help differentiate the causes of this devastating condition. METHODS The medical charts of teenagers with acute scrotal pain between January 2003 and December 2008 were reviewed retrospectively. RESULTS Seventy-six patients were included in this study, including 47 initially suspected of having testicular torsion and 29 suspected of having epididymo-orchitis. Testicular torsion was confirmed in 39 of the suspected 47 cases after surgical exploration. Twnety-one of these 39 testicular torsion patients underwent orchiectomy, and 18 were rescued and underwent orchiopexy. The mean pain duration was significantly longer in the orchiectomy group than the orchiopexy group (38.05 hours vs 14.14 hours, p = 0.009). In the testicular torsion group, fewer patients had elevated C-reactive protein levels no patients had pyuria, and the pain duration was shorter compared with the epididymo-orchitis group (5/11 vs 13/22 [p = 0.045], 0/28 vs 8/28 [p = 0.004] and 27.0 vs 74.5 hours [p = 0.0003], respectively). The sensitivity of color Dopper ultrasound in diagnosing testicular torsion and epididymo-orchitis was 84.09% vs 92.59%. Logistic regression for multivariate analysis showed that left side manifestation and pain duration were significantly different between testicular torsion and epididymo-orchitis with odds ratios of 4.76, p = 0.020 and 0.98, p = 0.029, respectively. CONCLUSIONS Pain duration and left side manifestation are independent risk factors of testicular torsion. Prompt surgical exploration should be done if testicular torsion is highly suspected.","PeriodicalId":10018,"journal":{"name":"Chang Gung medical journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30558144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Juvenile idiopathic arthritis is the most common pediatric rheumatic disease and is associated with significant long-term morbidity and mortality. There have been major advances in recent years in our understanding of the pathogenesis of JIA, the definition of disease control, and biological treatments for JIA. Multiple environmental and genetic factors have been linked with the onset and / or the exacerbation of JIA, including perinatal factors, viral and bacterial infections, epigenetic factors, and malnutrition. However, no single causative factor has been identified to date. As our understanding of the complex network of immune cells and inflammatory cytokines has improved, biologics have been developed to modulate the inflammatory processes. Indeed, a number of such biologics have been demonstrated effective for the treatment of JIA. Although biologic agents may alleviate the inflammation associated with JIA and prevent disability caused by joint destruction, continued and comprehensive observation is required to determine the long-term outcomes associated with such treatment.","PeriodicalId":10018,"journal":{"name":"Chang Gung medical journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30558198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
