Résumé

Background@#Deltoid function critically influences the results of reverse total shoulder arthroplasty (RTSA), and spontaneous deltoid attrition tears are frequently detected in cuff tear arthropathy (CTA) patients; however, the clinical impacts of these tears on RTSA outcomes are undetermined. Our aim was to determine the effect of spontaneous deltoid attrition tears on postoperative outcomes after RTSA without an additional deltoid procedure. @*Methods@#Seventy-two patients who underwent RTSA for CTA with preoperative magnetic resonance imaging (MRI) and a minimum clinical follow-up of 1 year (mean, 32 months) were retrospectively reviewed in the study. Patients with a history of previous shoulder surgery or injury were excluded. The presence and location of deltoid attrition tears were determined in preoperative MRI. Propensity score matching (1:1) was performed to construct tear and no-tear groups. Finally, 21 patients, matched with respect to age, sex, hand dominance, symptom duration, medical comorbidity (obesity, diabetes mellitus, and coronary artery disease), Hamada grade, and implant type, were assigned to each group. Clinical outcomes (functional scores, isometric power, and range of motion) in the two groups were compared. @*Results@#Deltoid attrition tears were detected in 21 of the 72 enrolled cases (29.1%). Anterolateral deltoid was the most frequent location and no tear was detected in the posterior deltoid. The tear rate increased with disease severity (Hamada G2, 4.8%; G3, 23.8%; > G4, 71.4%). No pre- or postoperative clinical variables differed significantly between the tear and no tear groups. @*Conclusions@#Deltoid attrition tears were detected in 29% of CTA patients who underwent RTSA. The most common site was the anterolateral region and tear prevalence tended to increase with CTA progression. However, RTSA was found to provide satisfactory outcomes regardless of the presence of a deltoid attrition tear.

Résumé

Background@#Lesions of the long head of the biceps tendon (LHBT) are one of the most common pathologies in patients with a rotator cuff tear. Although various procedures have been shown to be effective for treating LHBT lesions during rotator cuff repair, no consensus has been reached regarding the most effective treatment. The purpose of this study was to compare the outcomes of tenotomy vs subpectoral tenodesis of the LHBT in arthroscopic rotator cuff repair. @*Methods@#The records of 135 patients who underwent arthroscopic rotator cuff repair with biceps tenotomy or subpectoral tenodesis for a partial LHBT tear of > 50% were initially reviewed. Finally, 77 patients (38 patients with tenotomy and 39 patients with subpectoral tenodesis) with an intact rotator cuff, who underwent a functional evaluation at 1 year postoperatively, were enrolled in this retrospective study. @*Results@#The average follow-up was 13.3 ± 4.36 months (13.2 ± 1.4 months in the tenotomy group and 13.6 ± 2.7 months in the subpectoral tenodesis group; p = 0.416). Demographic and surgical data were not significantly different between the 2 groups.Preoperatively, biceps groove tenderness, Speed’s test, and Yergason test results were positive in 27.3%, 27.3%, and 10.4% of the study subjects, respectively. Compared with preoperative values, all functional scores including shoulder muscle power were significantly improved postoperatively, and no significant intergroup difference was observed (all p > 0.05). A visible Popeye deformity was not encountered in either group at the final follow-up. Eight patients in the tenotomy group and 7 patients in the subpectoral tenodesis group complained of mild anterior shoulder pain (p = 0.731), and 4 patients in each group complained of groove tenderness (p = 0.969). No surgical or postoperative complication occurred in either group. @*Conclusions@#Both biceps tenotomy and subpectoral tenodesis performed during rotator cuff repair improved pain and function and resulted in comparable clinical outcomes. Residual symptoms associated with the remnant LHBT in the groove may not be a problem after adhesion of LHBT.

Résumé

BACKGROUND AND OBJECTIVES@#We evaluated the correlation between video head impulse test (vHIT) and dizziness handicap inventory (DHI), which is commonly used to quantify severity of dizziness in vestibular neuritis (VN).SUBJECTS AND METHOD: Twenty VN patients undergoing vHIT either at the acute or follow-up stages of treatment were assessed by DHI questionnaire. Gain and gain asymmetry (GA) were correlated with DHI scores and abnormal vHIT rates were compared according to the severity of dizziness (mild ≤30; moderate-to-severe ≥32).@*RESULTS@#vHIT gains significantly increased from the acute to follow-up stages (from 0.45±0.18 to 0.70±0.25), whereas GA and DHI scores decreased (GA, from 0.36±0.15 to 0.22±0.18; DHI scores, from 35±26 to 23±23). Although vHIT gains or GA showed no correlation with DHI scores at the acute stage, vHIT gains showed significant correlation with DHI scores at the follow-up (R-sq=0.32, p=0.01) stage. vHIT gains and GA did not differ according to the severity of dizziness during the acute stage; however, vHIT gains (0.78±0.25) of patients with mild dizziness were significantly higher than those (0.51±0.14) with moderate-to-severe dizziness at the follow-up stage. During the follow-up, all patients with moderate-to-severe dizziness showed abnormal vHIT gain, but 43% of patients with mild dizziness showed abnormal vHIT gain, showing a significant difference (p<0.05).@*CONCLUSION@#Reduced vHIT gain was significantly correlated with high degrees of dizziness at the follow-up, but not at the acute stage, suggesting that high-frequency canal dysfunction is contributed in part by the subjective dizziness at the follow-up. Our findings suggest that vHIT might give an indirect evidence for implementing vestibular rehabilitation for enhancing impaired vestibular function and relieving subjective dizziness.

Résumé

Institute of Cancer Research (ICR) mice have been widely used in various research fields including toxicology, oncology, pharmacology, and pharmaceutical product safety testing for decades. However, annual tendency of research papers involving ICR mice in various biomedical fields has not been previously analyzed. In this study, we examined the numbers of papers that used ICR mice as experimental animals in the social science, natural science, engineering, medicine-pharmacy, marine agriculture-fishery, and art-kinesiology fields by analyzing big data. Numbers of ICR mouse-used papers gradually increased from 1961 to 2014, but small decreases were observed in 2015 and 2016. The largest number of ICR-used papers were published in the medicine-pharmacy field, followed by natural science and art-kinesiology fields. There were no ICR mouse-used papers in other fields. Furthermore, ICR mice have been widely employed in cell biology studies within the natural science field as well as in biochemistry and pathology in the medicine-pharmacy field. Few ICR mouse-used papers were published in exercise biochemistry and exercise nutrition in the art-kinesiology field. Regardless in most fields, the total numbers of published papers involving ICR mice were higher in 2014 than in other years, although the numbers in some fields including dentistry, veterinary science, and dermatology were high in 2016. Taken together, the present study shows that various ICR stocks, including Korl:ICR mice, are widely employed as experimental animals in various biomedical research fields.

Résumé

Residents who are currently in the process of completing graduate medical education (GME) will eventually become independently practicing professionals; therefore, the quality of GME is of enormous importance for our society. To improve the quality of GME in Korea, we, as young doctors, suggest that the government support funding for GME; make all possible efforts to ensure reasonable and sustainable working conditions for residents; implement adequate maternity plans; prohibit all kinds of unauthorized medical practice by other healthcare providers; and prevent all kinds of workplace violence toward residents. These measures to improve the quality of GME will surely benefit patient safety and the overall quality of healthcare in the future.

Résumé

BACKGROUND: Duct-to-duct anastomosis is the most common biliary reconstruction method in living donor liver transplantation. However, biliary complications can frequently occur. The objective of this study was to examine biliary complications and related risk factors of patients with living donor liver transplantation during the last 12 years in our institution. METHODS: Surgical outcomes of 252 consecutive patients with duct-to-duct anastomosis for biliary reconstruction in living donor liver transplantation between December 2000 and July 2012 were analyzed retrospectively. RESULTS: Among the 252 patients, there were 65 cases (25.8%) of biliary complications. Before 2010, the incidence of biliary complications was 30.4% (56 of 184 cases). After 2011, the incidence was significantly (P<0.05) decreased to 13.2% (nine out of 68 cases). The complication rate of anastomosis of two separated bile ducts of graft to recipient two separated bile ducts using cystic duct and common bile duct of recipient was 50% (10 out of 20), which was relatively higher compared to that of single to single duct anastomosis (47 out of 191, 24.6%) or multiple duct to single duct anastomosis (eight out of 41, 19.5%). CONCLUSIONS: Duct to duct anastomosis between two separated bile ducts of a graft to two separated bile ducts of a recipient, the most common biliary reconstruction method, was associated with higher rate of biliary complications. Complications related to biliary reconstruction of living donor liver transplantation was gradually decreased. Standardization of bile duct anastomosis might lead to sequential reduction of biliary complications in living donor liver transplantations.

Résumé

STUDY DESIGN: Retrospective study. PURPOSE: To propose a new radiographic index for occipito-cervical instability. OVERVIEW OF LITERATURE: Symptomatic atlanto-occipital instability requires the fusion of the atlanto-occipital joint. However, measurements of occipito-cervical translation using the Wiesel-Rothman technique, Power's ratio, and basion-axial interval are unreliable because the radiologic landmarks in the occipito-cervical junction lack clarity in radiography. METHODS: One hundred four asymptomatic subjects were evaluated with lateral cervical radiographs in neutral, flexion and extension. They were stratified by age and included 52 young (20-29 years) and 52 middle-aged adults (50-59 years). The four radiographic reference points were posterior edge of hard palate (hard palate), posteroinferior corner of the most posterior upper molar tooth (molar), posteroinferior corner of the C1 anterior ring (posterior C1), and posteroinferior corner of the C2 vertebral body (posterior C2). The distance from posterior C1 and posterior C2 to the above anatomical landmarks was measured to calculate the range of motion (ROM) on dynamic radiographs. To determine the difference between the two age groups, unpaired t-tests were used. The statistical significance level was set at p<0.05. RESULTS: The ROM was 4.8+/-7.3 mm between the hard palate and the posterior C1, 9.9+/-10.2 mm between the hard palate and the posterior C2, 1.7+/-7.2 mm between the molar to the posterior C1, and 10.4+/-12.1 mm between the molar to the posterior C2. There was no statistically significant difference for the ROM between the young- and the middle-aged groups. The intra-observer reliability for new radiographic index was good. The inter-observer reliability for the ROM measured by the hard palate was low, but was better than that by the molar. CONCLUSIONS: ROM measured by the hard palate might be a useful new radiographic index in cases of occipito-cervical instability.

Résumé

Although coffee is known to have antioxidant, anti-inflammatory, and antitumor properties, there have been few reports about the effect and mechanism of coffee compounds in colorectal cancer. Heat shock proteins (HSPs) are molecular chaperones that prevent cell death. Their expression is significantly elevated in many tumors and is accompanied by increased cell proliferation, metastasis and poor response to chemotherapy. In this study, we investigated the cytotoxicity of four bioactive compounds in coffee, namely, caffeine, caffeic acid, chlorogenic acid, and kahweol, in HT-29 human colon adenocarcinoma cells. Only kahweol showed significant cytotoxicity. Specifically, kahweol increased the expression of caspase-3, a pro-apoptotic factor, and decreased the expression of anti-apoptotic factors, such as Bcl-2 and phosphorylated Akt. In addition, kahweol significantly attenuated the expression of HSP70. Inhibition of HSP70 activity with triptolide increased kahweol-induced cytotoxicity. In contrast, overexpression of HSP70 significantly reduced kahweol-induced cell death. Taken together, these results demonstrate that kahweol inhibits colorectal tumor cell growth by promoting apoptosis and suppressing HSP70 expression.

Résumé

Although various animals have been used as models of cardiac valvular diseases in humans, the structural characteristics of cardiac valves in animals remain unclear. In this study, we investigated cardiac valves in representative animal models for the purpose of comparative anatomy. Adult hearts from three dogs, four goats, six rabbits, and six fowls were fixed with 10% neutral-buffered formalin and analyzed gross-anatomically. Cardiac appearance was spherical or oval in dogs, goats, and rabbits, whereas it had a long conical shape in fowls. Left atrioventricular (AV) valve was composed of membranous septal and parietal cusps connected to two papillary muscles in all animals. The right AV valve was composed of membranous septal, parietal, and angular cusps with three papillary muscles in dogs and goats, membranous septal and parietal cusps attached to four papillary muscles in rabbits, and a single muscular plate without any papillary muscles and chorda tendinae in fowls. Aortic valves with thin membranous right, left, and septal semilunar cusps in dogs, goats, and rabbits had a thick membrane with a bended free border in fowls. Pulmonary valve (PV) with membranous right, left, and intermediate semilunar cusps made a large central hole by being closely attached to the surrounding wall in dogs, goats, and rabbits, whereas it protruded into half of the lumen as a thick membrane in fowls. The membranous cusp of the PV was composed of several layers in dogs and goats but was a single layer in rabbits and fowls. These findings indicate that even if animals have two completely separated atria and ventricles each, cardiac valves have species-specific morphological characteristics, especially between mammals and fowls.

Résumé

PURPOSE: School screening allows for early detection and early treatment of scoliosis, with the purpose of reducing the number of patients requiring surgical treatment. Children between 10 and 14 years old are considered as good candidates for school screening tests of scoliosis. The purpose of the present study was to assess the epidemiological findings of idiopathic scoliosis in 11-year-old Korean adolescents. MATERIALS AND METHODS: A total of 37856 11-year-old adolescents were screened for scoliosis. There were 17110 girls and 20746 boys. Adolescents who were abnormal by Moire topography were subsequently assessed by standardized clinical and radiological examinations. A scoliotic curve was defined as 10degrees or more. RESULTS: The prevalence of scoliosis was 0.19% and most of the curves were small (10degrees to 19degrees). The ratio of boys to girls was 1:5.5 overall. Sixty adolescents (84.5%) exhibited single curvature. Thoracolumbar curves were the most common type of curve identified, followed by thoracic and lumbar curves. CONCLUSION: The prevalence of idiopathic scoliosis among 11-year-old Korean adolescents was 0.19%.

Résumé

BACKGROUND/AIMS: Ethanol administration causes intestinal epithelial cell damage by increasing intestinal permeability and the translocation of endotoxins from intestinal bacterial flora. Heat shock proteins (HSPs) are associated with recovery and protection from cell damage. The aim of the current study was to investigate differences in the expression of HSPs in the small intestine and the biochemical changes attributable to ethanol-induced intestinal damage. METHODS: Ethanol (20%) was injected intraperitoneally (2.75 g/kg, 5.5 g/kg, 8.25 g/kg) in ICR mice and the same volume of saline was administered to controls. After 1 hour, the proximal, middle, and distal segments were taken from the small intestine and the degree of damage was analyzed. In each segment, the expression of HSPs was analyzed by western blotting. The expression of inflammatory mediators including interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha), cyclooxygenase-2 (COX-2), and antioxidant enzyme such as glutathione-S-transferase were compared using real-time polymerase chain reaction assays. RESULTS: In the control group, HSP70 increased in all segments of small intestine. Additionally, increases in the expression of HSP40 and HSP90 in the distal regions and an increase in HSP32 in the middle regions were observed. After ethanol treatment, greater histological damage was observed in the distal small intestine and significant decreases in HSPs were observed generally. Increased expression of IL-1beta, TNF-alpha, and COX-2 was observed in small intestinal tissues exposed to ethanol-induced damage. However, there was no significant difference in the expression of an antioxidant enzyme. CONCLUSIONS: Significant differences in the expression of HSPs in different intestinal regions were observed. These differences may have been attributable to the distribution of intestinal bacteria.

Résumé

STUDY DESIGN: This is a retrospective study. PURPOSE: To evaluate the effect of the dynamic rotational plate to the intervertebral foraminal and discal height after anterior cervical discectomy and fusion. OVERVIEW OF LITERATURE: There is no report regarding the changes of foraminal and discal height following cervical dynamic rotational plating. METHODS: We reviewed the outcomes of 30 patients (36 levels), who were followed-up for an average of 15 months (range, 12-57 months) after undergoing fusions with anterior cervical dynamic rotational plating for cervical radiculopathy, from March 2005 to February 2009. The changes of foraminal and intervertebral discal height of the operated levels were observed on oblique and lateral radiographs obtained at the preoperative, postoperative and follow-up examinations. RESULTS: The foraminal and discal height increased sufficiently, immediately following the operation. However, follow-up results showed gradual decrease in the foraminal and discal height. After 6 months of the surgery, they showed little difference compared with the preoperative heights. However, clinically, patients showed improvements in radiating pain during the follow-up period. CONCLUSIONS: Anterior cervical dynamic rotational plating was an effective treatment modality for cervical radiculopathy without the deterioration of the foraminal and intervertebral discal height.

Résumé

BACKGROUND: First suggested by Brent in 1979, the pocket principle is an alternative method for patients for whom a microsurgical replantation is not feasible. We report the successful results of a modified palmar pocket method in adults. METHODS: Between 2004 and 2008, we treated 10 patients by nonmicrosurgical replantation using palmar pocketing. All patients were adults who sustained a complete fingertip amputation from the tip to lunula in a digits. In all of these patients, the amputation occurred due to a crush or avulsion-type injury, and a microsurgical replantation was not feasible. We used the palmar pocketing method following a composite graft in these patients and prepared the pocket in the subcutaneous layer of the ipsilateral palm. RESULTS: Of a total of 10 cases, nine had complete survival of the replantation and one had 20% partial necrosis. All of the cases were managed to conserve the fingernails, which led to acceptable cosmetic results. CONCLUSIONS: A composite graft and palmar pocketing in adult cases of fingertip injury constitute a simple, reliable operation for digital amputation extending from the tip to the lunula. These methods had satisfactory results.

Résumé

For implant treatment there must be sufficient bone to house the implant body. At least 5mm wide residual bone is needed and usually a 6mm width is preferred by clinicians. However, surgeons sometimes find patients with a narrow ridge, which makes it difficult to place an implant. Therefore, many clinicians perform bone graft or a ridge splitting technique to overcome these poor conditions. The time and cost can be reduced using the ridge splitting technique with immediate implant placement. Recently, many studies reported reliable consequences of ridge splitting technique. This paper reports a successful of implant placement with a ridge splitting technique in a very thin alveolar ridge.
