Influencia de la estructura de las redes personales sobre el desarrollo de procesos comunitarios en población desplazada / Influence of personal networks structure on the development of community processes in displaced population

El desplazamiento forzado afecta a más de 5 millones de personas en Colombia. El proceso de movilidad que experimentan los desplazados implica el debilitamiento de los vínculos con su entorno relacional y supone la privación del derecho de incidir a nivel sociopolítico. El sentido de comunidad, la participación y el empoderamiento sirven para comprender tanto el proceso de adaptación en la comunidad de destino, como el incremento de la participación comunitaria. Desde un enfoque estructural, el Análisis de Redes Sociales hace posible evaluar las redes de apoyo social de la población desplazada. Los objetivos de la investigación son (a) evaluar los tres procesos mencionados, (b) analizar las redes personales de los participantes y (c) examinar los posibles efectos que la estructura de las redes personales pueda ejercer sobre el desarrollo de los procesos comunitarios analizados. Los resultados indican que las propiedades estructurales de las redes inciden en el nivel de participación en actividades de desarrollo comunitario. Sin embargo, no se han detectado relaciones significativas entre los indicadores estructurales y los otros dos procesos comunitarios evaluados. Existen evidencias que indican que la densidad contribuye positivamente sobre la participación mientras que los parámetros de centralización afectan de forma negativa. Concluimos discutiendo el alcance de nuestros resultados para diseñar estrategias de intervención que promuevan la integración plena de los desplazados en la comunidad receptora.

Forced displacement affects over 5 million people in Colombia. The process of mobility experienced by displaced implies the weakening of the linkages with their relational environment and may involve the deprivation of the right to decide at socio-political level. The sense of community, the community engagement and the psychological empowerment display a strong potential to understand both the adaptation process in destination community, and the increase in community involvement. From a structural viewpoint, Social Network Analysis allows to evaluate the social support networks of the displaced population. The aims of this study are: (a) assess the three community processes; (b) analyze the personal networks structure of the displaced population; and (c) identify the potential effects that personal networks may exert on the development of community processes. Results suggest that structural properties of networks impact on the level of participation in community development activities. However, no significant relationships were identified between the structural measures and the other two community processes evaluated. Density contributes positively on community participation while centralization parameters affect in a negative way. We conclude discussing the applications of our results to design effective intervention strategies to promote the full integration of displaced population in the host community.

trazos para una metodología que permita comprender las razones de éxito y fracaso regional del control territorial de las farc-ep / features for a methodology which allows the understanding of the reasons of the regional success and failure behind the territorial control of farc-ep: the perspective of the qualitative comparative analysis (csqca)

El siguiente artículo recoge la propuesta metodológica de una investigación que se formuló con el propósito de dar cuenta de las razones que explican la diferente presencia que, a nivel territorial, expresan las Farc al término del periodo 1998-2010, tiempo en que la estrategia contrainsurgente del estado colombiano si bien logró desplazar a esta guerrilla de algunas regiones del país, en otras no lo consiguió. La perspectiva metodológica aquí planteada propone una estrategia analítica para identificar, definir y comprender las causas de la diversidad regional de la geografía de la guerra en Colombia. Tal estrategia se enfocó desde una óptica comparada a partir de un modelo desarrollado por la ciencia política denominado Conjunto de Variables para el Análisis Comparativo Cualitativo (csQCA en sus siglas en inglés, crips set of Qualitative Comprative Analysis).

The following article contains the methodological proposal of a piece of research that was carried out in order to give an account of the reasons which explain the different presence that, at the territorial level, the FARC express, at the end of the 1998 – 2010 period. That was a time in which the counterinsurgency strategy of the Colombian State even though it managed to move the guerrillas in some regions of the country, in others did not. The methodological perspective, which is posed here, proposes an analytical strategy to identify, to define, and to understand the causes of the regional diversity of the geography of the war in Colombia. Such a strategy has shifted from a comparative perspective based on a model developed by the political science called Set of Variables for Qualitative Comparative Analysis (csQCA in its acronym in English, crips set of Qualitative Comparative Analysis).

Clinical Results of Various Surgical Techniques for Isolated Fracture of Greater Tuberosity of Humerus

PURPOSE: To compare the clinical and radiologic outcomes of various surgical techniques for an isolated fracture of greater tuberosity of the humerus. MATERIALS AND METHODS: From February 2001 to December 2008, 31 patients, who underwent an operation for isolated greater tuberosity fracture and were followed up for more than 1 year, were enrolled in this study. The mean age at the time of operation was 49.3 years (range, 23-73 years). The operation methods included in this study were as follows: a transosseous suture using nonabsorbable suture material (16 cases), a fixation by cannulated screws (10 cases), tension band wiring (2 cases), bony fragment excision with rotator cuff repair (2 cases), and percutaneous pinning (1 case). RESULTS: At the last follow-up, the average Constant score was 79.4 and Korean Shoulder Score (KSS) was 81.2. Among the various operation methods used in this study, the transosseous suture had the highest scores with 82.5 in Constant score and 89.3 in KSS. Bone union was achieved at average 10.3 weeks (range, 7-15 weeks), and there were 2 cases in which the reoperation was required due to internal fixation failure. Postoperative shoulder stiffness occurred in 3 cases, and all the cases were done with the deltopectoral approach. CONCLUSION: Clinically and radiologically satisfactory results were obtained using various operation techniques for an isolated greater tuberosity fracture of the humerus. The transosseous suture showed relatively better results than the other methods used in this study. To achieve favorable clinical and radiologic results, it is important to select an appropriate surgical approach and fixation method according to the fracture site, degree of displacement, and size of fragment.

Comparison of Minimally Invasive Total Hip Arthroplasty versus Conventional Hemiarthroplasty for Displaced Femoral Neck Fractures in Active Elderly Patients / 전남의대학술지

Fractures of the femoral neck in elderly patients can be treated by internal fixation, hemiarthroplasty, or total hip arthroplasty (THA), and the treatment modality used should be determined on the basis of considerations of the degree of fracture displacement, age, functional demands, and the risk factors for surgery and anesthesia. We studied 85 active elderly patients who underwent minimally invasive two-incision THA or conventional bipolar hemiarthroplasty (BHA) within 2 weeks of injury for the treatment of acute displaced femoral neck fractures. Patients were followed up for a minimum of 24 months. The average operation times were 70 minutes in the THA group and 46 minutes in the BHA group (p=0.002), and average blood losses during the perioperative period were 921 cc and 892 cc, respectively (p=0.562). In the THA group, the average postoperative Harris hip score was 88.3 and the average Western Ontario and McMaster University score was 28.8, whereas in the BHA group the corresponding scores were 80.4 (p=0.006) and 32.5 (p=0.012), respectively. There were 2 cases of hip dislocation in the THA group, and 2 cases in the BHA group underwent conversion to THA. Our short-term follow-up results were better for minimally invasive two-incision THA than for conventional BHA for the treatment of acute displaced femoral neck fractures in active elderly patients.

A Case of Dental Implant Complication Coexisting with an Inverted Papilloma in the Nasal Cavity / 대한이비인후과학회지

Unexpected displacement of a dental implant into the maxillary sinus is an unusual but potential complication in dental procedure. A dental implant that migrates into the maxillary sinus often develops paranasal sinusitis and cause diverse peri-implant soft tissue complications. A 59-year-old man complaining of nasal obstruction for several months presented with a huge polypoid mass in the nasal cavity. He had undergone a dental implant procedure in the maxilla at a dental clinic seven years ago. The implant fixture was found displaced to the maxillary sinus. The migrated fixture and nasal mass were removed by endonasal endoscopic surgery and mini Caldwell-Luc operation. The pathology was diagnosed as an inverted papilloma. To our knowledge, this is the first case reported in the literature regarding a dental implant complication that developed independently of sinonasal inverted papilloma.

Restoration of Facial Deformity Caused by a Radicular Cyst after Marsupialization / 대한이비인후과학회지

Radicular cyst is the most common type of odontogenic cyst. The cyst originates from the maxilla occasionally, causes facial deformation and displacement of adjacent structures. An 11-year-old girl visited the outpatient clinic with the left cheek swelling and facial asymmetry. The cheek lesion was hard, accompanied by tenderness. The computed tomography (CT) scans revealed a large unilocular radicular cyst, which involved the floor of the left maxillary sinus, the palatine and alveolar process of the left maxilla. It was treated by transnasal marsupialization under endoscopic guidance. At the one postoperative year follow-up, facial asymmetry was restored and the marsupialization site was closed. The follow-up CT scan showed that the site of a radicular cyst was restored by bone formation. Therefore, we report a case of radicular cyst accompanied with facial asymmetry, which was restored after marsupialization. We also discuss the mechanism about the restoration of facial asymmetry.

Psychosocial impact of malocclusion in Spanish adolescents / 대한치과교정학회지

OBJECTIVE: To evaluate the psychosocial impact of malocclusion, determine its relationship with the severity of malocclusion, and assess the influence of gender and social class on this relationship in adolescents. METHODS: A random sample of 627 Spanish adolescents aged 12 - 15 years underwent intraoral examinations by 3 calibrated examiners (intraexaminer and interexaminer kappa > 0.85) at their schools. Psychosocial impact was measured through a self-rated Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). The severity of malocclusion was measured by the Index of Orthodontic Treatment Need (IOTN). Gender and social class were also recorded. RESULTS: The total PIDAQ score and those of its 4 subscales, social impact, psychological impact, aesthetic concern, and dental self-confidence, presented significant differences (p < or = 0.05 by analysis of variance) and linear relationships with the IOTN grades (p < or = 0.05 by linear regression). Stepwise linear regression models showed that the IOTN dental health component was a predictive variable of the total and subscale PIDAQ scores. Neither gender nor social class was an independent predictive variable of this relationship, except the linear model for psychological impact, where gender was a predictive variable. The occlusal conditions responsible for higher PIDAQ scores were increased overjet, impeded eruption, tooth displacement, and increased overbite. CONCLUSIONS: Malocclusion has a psychological impact in adolescents and this impact increases with the severity of malocclusion. Social class may not influence this association, but the psychological impact seems to be greater among girls.

Torque control during lingual anterior retraction without posterior appliances / 대한치과교정학회지

OBJECTIVE: To evaluate the factors that affect torque control during anterior retraction when utilizing the C-retractor with a palatal miniplate as an exclusive source of anchorage without posterior appliances. METHODS: The C-retractor was modeled using a 3-dimensional beam element (0.9-mm-diameter stainless-steel wire) attached to mesh bonding pads. Various vertical heights and 2 attachment positions for the lingual anterior retraction hooks (LARHs) were evaluated. A force of 200 g was applied from each side hook of the miniplate to the splinted segment of 6 or 8 anterior teeth. RESULTS: During anterior retraction, an increase in the LARH vertical height increased the amount of lingual root torque and intrusion of the incisors. In particular, with increasing vertical height, the tooth displacement pattern changed from controlled tipping to bodily displacement and then to lingual root displacement. The effects were enhanced when the LARH was located between the central and lateral incisors, as compared to when the LARH was located between the lateral incisors and canines. CONCLUSIONS: Three-dimensional lingual anterior retraction of the 6 or 8 anterior teeth can be accomplished using the palatal miniplate as the only anchorage source. Using LARHs at different heights or positions affects the quality of torque and intrusion.

Treatment of the Distal Radius Fractures in the Elderly Patients

Distal radius fractures are one of the most common types of fractures in the elderly. It is well documented that increased risk of a distal radius fracture in older patients is associated with decreased bone mineral density. Also, low bone mineral density increased severity of fracture and instability of fracture after reduction. Fracture displacement in the elderly does not necessarily result in functional impairment. Therefore, conservative treatment has been a mainstay treatment even in unstable fracture in the elderly. However, there is an increasing trend toward operative treatment recently, because functional demand increased in the elderly due to active life style and volar locking plate fixation enables the elderly early return to daily activity even in osteoporotic distal radius fracture.

Abdominal Advancement Flap as Oncoplastic Breast Conservation: Report of Seven Cases and Their Cosmetic Results / 한국유방암학회지

An abdominal advancement flap (AAF) is a flap that pulls the elevated abdominal skin up and creates the shape of the inferior portion of the breast by making a neo-inframammary fold. Seven patients underwent remodeling using an AAF or a method combining an AAF with other volume displacement techniques after partial mastectomy. The excision volume ranged from 15% to 35%. AAF with only mobilization of the gland flaps was performed in two cases, with lateral mammoplasty in one case, with the round block technique (RBT) in one case, with a modified RBT in one case, and with medial mammoplasty in two cases. Although one patient treated with a RBT had a partial blood-flow insufficiency of the nipple-areola complex, it improved with conservative treatment. The cosmetic results were found to be excellent in three cases, good in three, and fair in one case.

Primary Breast Augmentation with Anatomical Form-stable Implant

The Natrelle(TM) 410 (Allergan Inc., Irvine, CA, USA) shaped, form-stable silicone gel implant was introduced in Europe in 1993. Its "form stability" relates to increased cohesiveness or stiffness of the gel filler, allowing the implant to maintain its shape in the upright position. The anatomical form-stable implant is helpful for reducing ripples and provides more natural looking due to less upper pole fullness, so it has some benefits for the thin patients. And it provides more expansion to the lower pole, it has also benefits for the ptotic breasts or constricted breasts. I have experienced 69 cases with anatomical form-stable implants (52 Polytech Replicon(R) (POLYTECH Health & Aesthetics, Dieburg, Germany) implants, 85 Natrelle(TM) 410 implants) from February to December of 2012. The most common used implants are MF295 g of Natrelle(TM) 410 and high profile 315 g of Polytech Replicon(R). I did reoperations for 2 breasts of 2 patients. One was due to hematoma and the other was due to displacement. Both cases are my early experiences of shaped implants. There is no other complication yet. I need longer follow-up period for the appropriate evaluation. In my early experiences, the results of anatomical form-stable implants seem to make less fullness of upper pole, less ripples, more tightness, and similar recovery periods in contrast with the results of round textured implants.

Intrapelvic Anterior Plate Fixation for Crescent Fracture-Dislocation of Sacroiliac Joint

PURPOSE: To evaluate the radiological and clinical outcomes of intrapelvic anterior plate fixations for Day Classification Type II crescent fracture-dislocations of sacroiliac joints. MATERIALS AND METHODS: Ten patients who had undertaken the surgical treatment for the sacroiliac joint from 2006 to 2012 were enrolled in this study. All cases fell into Type II by Day Classification for sacroiliac joint injuries. For surgical treatments, the plate fixation through the intra-pelvic anterior approach was first performed for all cases and anterior ring fixation was performed in 4 cases with more severely displaced anterior pelvic ring injuries. Then, radiological and clinical evaluation was implemented. RESULTS: The bone union was observed from all patients whom performed the surgical fixation. In the radiological results, 9 cases with the anatomic and nearly-anatomic reductions were observed. Out of the 10 cases which performed the rotational displacement analysis, there were 3 excellent cases, 6 good cases and 1 fair case. The 10 cases that performed the deformity index and vertical displacement analysis, less variations were observed in the anterior ring fixations after intra-pelvic anterior plate fixation group. According to the clinical results, 4 excellent cases, 3 good cases, and 3 moderate cases were observed. CONCLUSION: In the Type II crescent fracture-dislocation of sacroiliac joint, the intrapelvic anterior plate fixation achieved satisfactory anatomical reductions, radiological stabilities and clinical results.

Arthroscopic Assisted Intra-Articular Reduction and Internal Fixation of Tibia Plateau Fracture

PURPOSE: We evaluated the results of arthroscopic intra-articular reduction and internal fixation of tibial plateau fractures without cortical window along with any additional bone grafts. MATERIALS AND METHODS: From March 2006 to March 2009, twelve patients with arthroscopic intra-articular reduction and internal fixation of tibial plateau fractures over 5 mm in depression and displacement on the articular surface in computed tomography (CT) were enrolled in this study. We reduced or removed the depressed fracture fragment using freer without making a cortical window. Then, we accomplished internal fixation by a cannulated screw. All cases have not received bone graft. Both the postoperative clinical and radiological results were evaluated by the Rasmussen system. RESULTS: The fractures were healed completely in an average of 9 (range from 7 to 12) weeks. According to Rasmussen classification, we obtained satisfactory clinical results as excellent in 8 cases, good in 3 cases, and fair in 1 case; and radiological results were excellent in 7 cases and good in 5 cases. CONCLUSION: We consider that arthroscopic intra-articular reduction and internal fixation of tibial plateau fractures without cortical window and any additional bone grafts is are a useful methods for attaining satisfactory results.

Acute Schmorl Node in Dorsal Spine: An Unusual Cause of a Sudden Onset of Severe Back Pain in a Young Female

Schmorl nodes represent displacement of intervertebral disc tissue into the vertebral body and have been considered as an asymptomatic incidental radiological finding on plain radiographs, computed tomography and magnetic resonance imaging (MRI). Although uncommon, acute symptomatic Schmorl nodes causing severe back pain do occur. We report here an unusual case of acute painful Schmorl node in a young healthy woman, with no previous trauma, presenting with a sudden significant localized back pain within hours accompanied by characteristic findings on a MRI scan. We reviewed all reports of symptomatic Schmorl nodes known in the literature, focusing mainly on MRI findings, and recent treatment options.

Displacement of dental implants into the focal osteoporotic bone marrow defect: a report of three cases

Focal osteoporotic bone marrow defect (FOBMD) is a radiolucent area corresponding to the presence of hematopoietic tissue rarely found in the jaws. FOBMD is most commonly located in the mandibular edentulous posterior area of a middle-aged female. From November 2011 to November 2012, we experienced three cases involving removal of implants that had accidentally fallen into the FOBMD area. All patients happened to be female, with a mean age of 54 years (range: 51-60 years). One case involved hypoesthesia of the lower lip and chin, while two cases healed without any complication. Displacement of an implant into the FOBMD area is an unusual event, which occurs rarely during placement of a dental fixture. The purpose of this study was to report on three cases of FOBMD and to provide a review of related literature.

Transarticular Fixation of Akin Osteotomy on Patients with Hallux Valgus after Resection of Medial Protrusion of Base of Proximal Phalanx / 대한족부족관절학회지

PURPOSE: When medial protrusion in the base of proximal phalanx is severe from removing metatarsal bunion during the hallux valgus surgery, it could lead to skin irritation and medial pain after the surgery. The purpose of this paper was to report our clinical and radiographic results with transarticular fixation of Akin osteotomy for the treatment of patients with hallux valgus after resection of the medial protrusion of base of the proximal phalanx. MATERIALS AND METHODS: Our study is subject to 34 cases of 30 patients who went through proximal phalanx medial corticectomy among patients undergone both hallux valgus surgery and Akin osteotomy at our institution from March 2006 to March 2012. In all cases, we used absorbable suture material through the articular surface for Akin osteotomy after resection of the medial protrusion in proximal phalanx. Radiographs were reviewed to assess the union and displacement of osteotomy site at the time of postoperative 6 months. The clinical results were assessed by using AOFAS score and complication such as skin irritation and pain. RESULTS: AOFAS score was improved from average 44 points(36-58), before operation and average 87 points(74-96), 12 months after operation. In two cases, partial union was suspected in radiological perspective, however, complete union on the osteotomy site was observed in all cases, 12 months after the operation. No patients was dissatisfied with pain, joint discomfort, skin irritation and inflammation from the knot. CONCLUSION: When medial protrusion in the base of proximal phalanx is severe from removing metatarsal bunion during the hallux valgus surgery, We have good results by transarticular fixation of Akin osteotomy using absorbable suture material.

Condylar repositioning using centric relation bite in bimaxillary surgery / 대한치과교정학회지

OBJECTIVE: The purpose of this study was to evaluate displacement of the mandibular condyle after orthognathic surgery using a condylar-repositioning device. METHODS: The patient group comprised 20 adults who underwent bimaxillary surgery between August 2008 and July 2011. The degree of condylar displacement was measured by pre- and postoperative tomographic analysis using centric relation bite and a wire during surgery. A survey assessing temporomandibular joint (TMJ) sound, pain, and locking was performed. The 20 tomographs and surveys were analyzed using the Wilcoxon signed-rank test and McNemar's test, respectively. RESULTS: No significant changes were observed in the anterior, superior, or posterior joint space of the TMJ (p > 0.05). In addition, no significant change was observed in TMJ sound (p > 0.05). However, TMJ pain and locking both decreased significantly after surgery (p < 0.05). CONCLUSIONS: Due to its simplicity, this method may be feasible and useful for repositioning condyles.

Combined Anti-VEGF and C3F8 Injection for Large Submacular Hemorrhage Secondary to Age-Related Macular Degeneration

PURPOSE: To evaluate the effect of intravitreal expansile gas (C3F8) with anti-VEGF injection for the treatment of large submacular hemorrhage (SMH) secondary to age-related macular degeneration (ARMD). METHODS: In this report, 18 eyes of 18 patients with large SMH secondary to ARMD were treated with a simultaneous injection of 0.3 cc C3F8 and 0.05 ml anti-VEGF intravitrealy. RESULTS: The mean age was 64.89 +/- 5.68 years and the mean size of SMH was 4.44 +/- 1.25 disc diameters (DD). The minimum follow-up period was 12 months (range: 12-17 months). Mean preoperative best corrected visual acuity (BCVA) was 1.72 +/- 0.56 log MAR which improved significantly to 1.01 +/- 0.68 log MAR at 12 months (p = 0.002). SMH displacement occurred in all eyes. BCVA improved 2 or more lines in 11 eyes (61.1%) and deteriorated in 1 eye (5.6%). CONCLUSIONS: In this report, intravitreal injection of an expansible gas (C3F8) with anti-VEGF produced successful results in anatomical displacement of SMH and early visual improvement.

Effect of simultaneous therapy of arthrocentesis and occlusal splints on temporomandibular disorders: anterior disc displacement without reduction

OBJECTIVES: This study sought to evaluate the effect of simultaneous application of arthrocentesis and occlusal splint. MATERIALS AND METHODS: A retrospective study of 43 patients (3 males, 40 females) whose symptoms had improved was conducted at the Department of Oral and Maxillofacial Surgery, Dong-A University Hospital between 2008 and 2010. Subjects were divided into three groups: Group A (17 patients with arthrocentesis and occlusal splints simultaneously applied), Group B (13 patients whose symptoms did not improve with occlusal splints, undergoing arthrocentesis after occlusal splint use for 8 weeks), and Group C (13 patients that only used occlusal splints). We compared these groups in maximum comfortable opening (MCO) and the visual analogue scale of pain and noise. Follow-up was performed at 1 week, 1 month, 3 months, and 6 months. RESULTS: The improvement of symptoms was noted in all three groups, but Group A had a quicker improvement than the other groups, in terms of pain reduction and MCO increases. CONCLUSION: The simultaneous application of arthrocentesis and occlusal splints can reduce patient discomfort more quickly.
