O objetivo deste estudo foi analisar epidemiologicamente essas lesões, os métodos diagnósticos, e identificar fatores preditivos relacionados a maior morbidade e mortalidade nos pacientes acometidos por este tipo de lesão. Foi realizado estudo retrospectivo, entre 1994 e 2012, com 25 pacientes operados por perfuração esofágica traumática nesse período. Mecanismo de trauma, parâmetros fisiológicos, localização, grau da lesão esofágica, presença de lesões associadas e índices de trauma foram analisados. O sexo masculino foi o mais acometido (88%), com faixa etária entre 15 e 65 anos (média de 29,2 anos), tendo FPAF como principal etiologia (68%) e acometendo principalmente o esôfago cervical (68%). Em 17 pacientes, a confirmação diagnóstica ocorreu por meio de exames subsidiários, sendo que os mais realizados foram Endoscopia Digestiva Alta e Tomografia Computadorizada. Nos demais 8 casos o diagnóstico foi intra-operatório. O intervalo de tempo entre o trauma e a cirurgia foi inferior a 6 horas em 40% dos traumas penetrantes e inferior a 24 horas em 80% dos casos, independente do mecanismo. A sutura acompanhada da drenagem foi o tratamento cirúrgico mais frequente (92% dos casos). A morbidade global foi 72%, sendo a pneumonia a complicação mais prevalente, e 48% decorrentes de complicações relacionadas diretamente à lesão esofágica, sendo a infecção de ferida operatória e a fístula as mais comuns. A mortalidade foi 16%, e ocorreu por choque hipovolêmico (2 casos) ou por sepse (2 casos). Valores de ISS maiores que 25 e grau da lesão OIS > 3 foram preditores para a ocorrência de fístula (24% dos casos). Não foi observado nenhum fator que isolado concorreu para o aparecimento de complicações em geral. Pacientes com idade superior a 54 anos, PAS na admissão inferior a 90 mmHg e TRISS menor que 0,5, foram identificados com maior mortalidade. Conclui-se que os fatores descritos estão associados a maior ocorrência de fístula e mortalidade, porém, por se tratar de casuística retrospectiva e pequena, novos estudos serão necessários para validação dessas informações / Abstract: Injuries to the esophagus are rare, with difficult diagnosis, and are commonly associated with significant morbidity and mortality. The aim of this study was to analyze the epidemiology of these lesions, diagnostic methods, trying to identify predictive factors related to increased morbidity and mortality in this specific population. A retrospective study of 25 patients submitted to surgery with traumatic penetrating esophageal injuries from 1994 to 2012 was performed. Mechanism of injury, physiologic measures, injury location, esophageal injury grade, presence of associated injuries and trauma scores were evaluated. Male patients were the most affected accounting for 88% of the cases, with ages between 15 and 65 years (mean 29.2 years). Gunshot injuries were the main etiology (68%) and happened more often in the cervical topography of the esophagus (68%). In 17 patients ancillary tests were performed to confirm the diagnosis, among these, the most performed tests were Upper Digestive Endoscopy and CT scan. In 8 cases, esophageal injuries were diagnosed intraoperatively. The length of time between trauma and surgery was less than 6 hours in 40% of the penetrating injuries and less than 24 hours in 80% overall, despite the mechanism of injury. The suture followed by drainage was the most frequent surgical method performed (92% of cases). The overall morbidity was 72%, with pneumonia as the most prevalent. 48% of the complications were directly related to the esophageal injury, and operative wound infection and fistula were the most common. Mortality was 16% and occurred in patients with hypovolemic shock (2 cases) or sepsis (2 cases). ISS values greater than 25 and the injury AAST-OIS grade > 3 were predictors for the occurrence of fistula (24% of cases). No other isolated factors were observed to contribute to the surge of general complications. Patients over 54 years old, SBP lower than 90 mmHg and TRISS lower than 0.5 on admission were identified with higher mortality. In conclusion, the factors described herein are associated with higher incidence of fistula and mortality, but due to a small and retrospective case series, further studies are required to validate this information / Mestrado / Fisiopatologia Cirúrgica / Mestre em Ciências

Afin de modéliser l'évolution de l’infection par le chikungunya (CHIK), son impact, et les facteurs pronostiques de chronicité, nous avons travaillé en trois parties. L'impact à long terme de l’épidémie de CHIK en 2005-2006 à la Réunion a été estimé en calculant la proportion de patients en phase chronique au cours du temps et la charge globale de morbidité du CHIK par la méthode des années de vie ajustées sur l'invalidité (méthode DALY de l’OMS, qui prend en compte les années de vie perdues en raison de la mortalité prématurée et des années de vie vécues avec une incapacité). Ainsi entre 51,2 et 65,3% des patients étaient estimés symptomatiques après 1 an et 0% à15,2% après 5 ans. Le total d’années de vie en bonne santé perdues à la Réunion a été estimé à 65-73/1000 personnes, 55,5% des pertes concernant la population active (les 20 à 60 ans), et 86% étant dues à la persistance de rhumatismes post-CHIK (phase chronique). Les facteurs pronostiques de la persistance de rhumatismes et de l’altération de la qualité de vie (QdV) à long terme (30 mois) ont été étudiés dans une cohorte des gendarmes dont 25% étaient infectés (CHIK+). Etre CHIK+, avoir des comorbidités et un moral déprimé pendant la phase aiguë étaient prédictifs de la persistance d’arthrite comme d’arthralgies. De plus, la présence d’arthralgies ou arthrite à six mois était très prédictive de la persistance des mêmes rhumatismes à 30 mois. / To model the evolution of chikungunya virus (CHIK) infection, its impact and the prognostic factors of post-CHIK rheumatism and quality of life, we worked in three parts. The long-term impact of the 2005-2006 CHIK outbreaks in Reunion Island was estimated by calculating the proportion of chronic patients over time and the global burden of CHIK using the Disability Adjusted Life Years (DALY) method. This method sums the years of life lost due to premature mortality and the years lived with disability. Between 51.2 and 65.3% of patients were estimated chronic after 1 year and 0%-15.2% after 5 years. The global disease burden of CHIK was estimated 65-73 DALYs/1000 persons, 55.5% concerning the active population (20-60 years old), and 86% due to persistence of post-CHIK rheumatisms. Prognostic factors of the long-term (30 months) rheumatisms and impaired quality of life (QoL) were studied in a cohort of French army policemen (25% CHIK infected: CHIK+). Being CHIK+, suffering of comorbidity and having depressed mood during the acute stage were predictive for both persistent arthritis and arthralgias at 30 months. In addition, suffering of either arthralgias or arthritis at six months was predictive of the same symptoms at 30 months. Determinants of impaired QoL were CHIK infection and comorbidity, in addition to older age, work-stoppage during the acute infection and arthritis at 6 months for the QoL physical component, and depressed mood at 6 months for the mental health component.Association between the severity of initial CHIK-stages and recovery were studied using multiple correspondence analysis (MCA).

Cette thèse cherche à optimiser l’utilisation du génotypage et des scores de gravité dans la drépanocytose. L’aspect diagnostic génétique ne nous semblait pas poser problème jusqu’à ce que nous rencontrions un cas très atypique d’hétérozygotie A/S avec délétion en mosaïque du gène β-globine qui nous a conduits à réfléchir sur une nouvelle forme génétique potentielle de syndrome drépanocytaire majeur. Pour ce qui est des gènes modificateurs de drépanocytose, nous avons voulu faciliter leur l’accès en proposant, pour deux d’entre eux (haplotypes β-globine et G6PD), une méthode de génotypage rapide par HRM et/ou FRET. Notre travail a consisté ensuite en la validation d’un score de sévérité pédiatrique décrit initialement par Van den Tweel. De façon inattendue, les résultats nous ont amenés à nous interroger sur le rôle exact du génotype α-globine dans la drépanocytose avec un possible effet âge-dépendant. Enfin, nous avons étudié les fréquences alléliques des principaux polymorphismes influant sur l’activité des opiacés: une résistance pharmacologique (gènes OPRM1 et COMT) est apparue peu probable mais une proportion non négligeable de drépanocytaires pourrait avoir des génotypes ABCB1 et UGT2B7 défavorables à la biodisponibilité des opiacés / This work is submitted for a PhD thesis in the field of red cell haematology. Sickle cell disease (SCD) is a monogenic disorder under polygenic and environmental control. The aim of this work was to integrate genotyping results from patients' DNA into the determination of the disease severity scores. Through a large population of SCD patients, we have discovered an atypical case of βA / βS heterozygosity namely, a mosaicism deletion of the beta-globin gene. This represents a new SCD complex situation for molecular diagnosis. Further investigations have led to set up a new genotyping method by using HRM and/or FRET for the determination of two SCD modifiers (beta-globin haplotypes and G6PD deficiency). By using a paediatric severity score of the disease proposed by Van den Tweel, our results show that there is a possible age-dependent effect of the alpha-globin gene in the severity of SCD. Finally, we studied the allelic frequencies of the main opiate-related polymorphisms: a pharmacological resistance (OPRM1 and COMT genes) seemed unlikely but a quite important proportion of patients could have both an ABCB1 and a UGT2B7 genotype unfavorable for opiates bioavailability

<p>Kompleksnost visokoenergetskih preloma platoa i pilona tibije i njihova udruženost sa značajnim povredama mekog tkiva oko pripadajućeg zgloba veoma je dobro opisana. Lečenje ima za cilj da multifragmentarni prelomi platoa i pilona tibije postanu stabilni, artikularno poravnani, bezbolni, da koleno i skočni zglob budu pokretni i da se minimizira rizik do nastanka posttraumatskog osteoartritisa. Aparat po Ilizarovu sa nategnutim iglama, koristi opterećenje da stvori jedinstvenu podr&scaron;ku za zglob i stabilnu imobilizacju preloma da se postigne njegovo srastanje. Ovo omogućuje ranu pokretljivost zgloba bez rizika od gubitka redukcije. Cilj istraživanja je procena i poređenje rezultata lečenja unutarzglobnih vi&scaron;ekomadnih preloma kostiju proksimalnog i distalnog okrajka potkolenice tretiranih spoljnjim unilateralnim rigidnim fiksatorom i aparatom po Ilizarovu primenom ASAMI ko&scaron;tanog skoring sistema i funkcionalnog skoring sistema po Karlstrom &ndash; Olerudu.Takođe je jedan od ciljeva istraživanja bio da se uoče faktori koji utiču na različite rezultate lečenja unutarzglobnih vi&scaron;ekomadnih preloma kostiju gornjeg i donjeg okrajka potkolenice tretiranih spoljnim unilateralnim rigidnim fiksatorom i aparatom po Ilizarovu. Istraživanje je dizajnirano kao kontrolisana komparativna klinička studija a podaci su se prikupljali retrospektivno i delom prospektivno na osnovu medicinske dokumentacije od 2008. do 2013. godine. Studija je u potpunosti izvedena na Klinici za ortopediju i traumatologiju Kliničkog centra Vojvodina u Novom Sadu. Studija je obuhvatila ukupno 103 ispitanika kod kojih je u toku 2008 do 2013. godine postavljena dijagnoza unutarzglobnog vi&scaron;ekomadnog preloma gornjeg ili donjeg okrajka tibije. Ispitanici koji su obuhvaćeni ovim kliničkim istraživanjem razvrstani su u tri grupe: Prvu grupu od 53 ispitanika činili su oni sa vi&scaron;ekomadnim unutarzglobnim otvorenim ili zatvorenim prelomima gornjeg ili donjeg okrajka kostiju potkolenice lečenih isključivo spoljnjim unilateralnim rigidnim fiksatorom. Drugu grupu ispitanika, njih 31, činili su oni sa vi&scaron;ekomadnim unutarzglobnim otvorenim ili zatvorenim prelomima gornjeg ili donjeg okrajka kostiju potkolenice lečenih isključivo aparatom po Ilizarovu. Treću grupu činila su 19 ispitanika sa vi&scaron;ekomadnim unutarzglobnim otvorenim ili zatvorenim prelomima gornjeg ili donjeg okrajka kostiju potkolenice koji su lečenje započeli spoljnjim unilateralnim rigidnim fiksatorom, a u kasnijem periodu zbog nastalih komplikacija (lo&scaron;e srastanje, produženo srastanje, nesrastanje, infekcija, pseudoartroza) lečenje nastavili konverzijom spoljnjeg unilateralnog rigidnog fiksatora u aparat po Ilizarovu. Osnovni izvor podataka za prikazano istraživanje bio je protokol formiran za svakog bolesnika pojedinačno, istorije bolesti i poliklinička evidencija. Za potrebe istraživanja dizajniran je protokol istraživanja gde su se prikupljeni podaci analizirali hronolo&scaron;ki : podaci o pacijentu, klinički nalaz na prijemu, postoperativni tok, monitoring aparata, klinički nalaz na otpustu i klinički nalaz na kontrolama od 6, 12 i 18 meseci. Kliničke nalaze na kontrolama na 6, 12 i 18 meseci beležili smo upotrebom skoring sistema ASAMI ( Udruženja za istraživanje i primenu metoda po Ilizarovu) &ndash; za ko&scaron;tane rezultate, i Karlstrom &ndash; Oleruda za procenu funkcionalnih rezultata. Neki do najvažnih rezultata dobijenih prilikom ovog istraživanja jesu da je najbrže vreme srastanja imala grupa Ilizarov, nakon 16&plusmn;2 nedelja. Grupa konverzija zabeležila je prosečno vreme srastanja u 17&plusmn;2 nedelji, dok je kod ispitanika u grupi fiksator zabeženo srastanje u 21&plusmn;4 nedelji. Pojava povr&scaron;nih i dubokih infekcija značajno je veća kod grupe tretiranih spoljnim unilateralnim fiksatorom nego kod grupa tretiranih aparatom po Ilizarovu. Vreme postizanje ranog, punog oslonca na operisani ekstremitet je značajno kraće kod grupe Ilizarov i konverzija nego kod grupe fiksator. Procena ko&scaron;tanih rezultata kori&scaron;ćenjem ASAMI bodovnog sistema ko&scaron;tanog srastanja ukazuje na statistički značajno bolje rezultate kod grupa Ilizarov i konverzija u odnosu na grupu spoljnji fiksator u periodu praćenja i analize na 6,12 i 18 meseci. Funkcionalni rezultati primenom sistema funkcionalne evaluacije po Karlstrom &ndash; Olerudu govore u prilog značajno statistički boljim rezultatima kod grupe Ilizarov i konverzija u odnosu na grupu spoljni fiksator u periodima praćenja i analize na 6,12 i 18 meseci. Na osnovu dobijenih rezultata dolazimo do zaključka da je tretman ispitanika sa multifragmentarnim, intraarikularnim prelomima gornjeg i donjeg okrajka kostiju potkolenice znatno efikasniji aparatom po Ilizarovu &scaron;to sveukupno daje smernice za brži i kvalitetniji oporavak ispitanika i njihov povratak svakodnevnim aktivnostima sa &scaron;to manjim posttraumatskim sekvelama.</p> / <p>The complexity of high-energy fractures of the tibia plateau and pilons and their association with significant violations of the soft tissue around the corresponding joint is well described in the literature. Main aim of the treatment is to multiple fractures of the tibia plateau and pilon become stable, articularly aligned, without pain, and with full motion in the knee and ankle joint with minimum risk for post-traumatic osteoarthritis. Ilizarov apparatus with taut needles is used to create a unique load support for the ankle and create conditions for good healing. This strong stability allows early joint movement, without risk of loss position of fracture parts. The aim of this research is assessment and comparation of the results of treatment, for intraarticular multiple fractures of the proximal and distal part of lower leg tretaed with unilateral external rigid fixator and Ilizarov apparatus, with ASAMI bone scoring system and functional scoring sistem by Karlstrom &ndash; Olerud. One of the goals of the study was to detect factors which affecting different treatment results of the intraarticular multiple fractures of the proximal and distal part of lower leg, tretaed with unilateral external rigid fixator and Ilizarov apparatus. The study was designed as a controlled comparative clinical study and data were collected retrospectively and prospectively form medical records from 2008 to 2013. The study has been fully implemented at the Department for orthopedic surgery and traumatology in the Clinical Center of Vojvodina in Novi Sad and included 103 patients who had intraarticular multiple fractures of the proximal and distal part of tibia. Subjects covered in this clinical study were classified into three groups: The first group of 53 patients were with intraartiulary multifragmentary open or closed fractures of the upper or distal part of lower leg, treated exclusively with unilateral external rigid fixator. The second group included 31 patients with intraarticular open or closed fractures of the upper or distal lower leg, treated exclusively with Ilizarov apparatus. 19 patients made the third group with intraarticulary open or closed fractures of the upper or distal lower leg, which were treated at the begining with unilateral external rigid fixator and later because of the complications (poor or prolonged healing, nonunion, infection and pseudoarthrosis) tretment was continued by Ilizarov apparatus. The main source of data for this study was protocol wich was established for each patient individually. In this protocol collected data analyzed by date: patient data, clinical findings at admission, postoperative course, monitoring apparatus, clinical findings at discharge and clinical findings at the controls which were at 6, 12 and 18 months after surgery. Clinical findings at control examinations (6, 12 and 18 months after surgery), we recorded by scoring system ASAMI (Association for the Study and Application of the Methods of Ilizarov) - that represent the results of the bone healing, and Karlstrom - Olerud for assessment functional outcomes. The most important results were: the fastest time of bone union was in the group of Ilizarov, and it was after 16 &plusmn; 2 weeks and the third group (conversion group) recorded an average time after 17 &plusmn; 2 weeks, while the patients in the first group (external fixator) had average time of union after 21 &plusmn; 4 week. The appearance of superficial and deep infection was significantly higher in the group treated with unilateral external fixator than in the group treated by the Ilizarov apparatus. Fastest full weight bearing on the injured leg, had patients in the group treated with Ilizarov apparatus. Evaluation of results using bone ASAMI fusion scoring system indicating a statistically significantly better results in the conversion and Ilizarov group compared to the group of external fixator in the period of monitoring at 6,12 and 18 months after surgery. Functional results by Karlstrom - Olerud scoring system show statistically significantly better results in the Ilizarov and conversion group contrary to the external fixator group in periods of monitoring at 6,12 and 18 months. Based on these results we conclude that the treatment of subjects with intraarticulary, multifragmentary fractures of the upper and lower part of the lower leg are more efficient after Ilizarov apparatus which provides overall guidance for faster and better recovery of patients and their return to their daily activities with minimal post-traumatic sequelae.</p>

Objetivo: Comparar o tratamento cirúrgico convencional das varizes de membros inferiores com a escleroterapia com espuma ecoguiada nos pacientes com úlcera venosa. Como objetivo secundário, foi comparada a incidência de complicações com os métodos empregados e a melhora na qualidade de vida após a realização dos procedimentos. Casuística e Métodos: Foi realizado um estudo randomizado e prospectivo de 49 pacientes com úlceras ativas (C6), que foram submetidos ao tratamento cirúrgico (28 membros) ou escleroterapia espuma (23 membros), tendo como desfechos a cicatrização de úlceras de origem venosa, complicações do tratamento e qualidade de vida,. Os pacientes completaram o Questionário Aberdeen Veias Varicosas (QAVV), o escore de severidade clínica venoso (ESCV) e o Escore de Incapacidade Venosa (EIV). Resultados: A média e desvio padrão de acompanhamento foi de 502 ± 220 dias. A úlcera cicatrizou em 100% e 91,3% dos doentes tratados com cirurgia ou escleroterapia espuma, respectivamente (P > 0,05). QAVV, ESCV e EIV melhoraram em ambos os grupos após o tratamento. Não houve diferenças significativas no resultado final do QAVV, ESCV e EIV entre os dois grupos, vários meses após os procedimentos (p = 0,45, 0,58 e 0,66, respectivamente; Mann- Whitney U). As complicações ocorreram em 14,2% e 13,0% nos grupos cirúrgico e escleroterapia com espuma, respectivamente. Conclusão: A escleroterapia com espuma não foi inferior ao tratamento cirúrgico de úlceras venosas. Portanto a escleroterapia é uma alternativa ao tratamento cirúrgico, particularmente adequada para pacientes de alto risco cirúrgico que apresentam insuficiência venosa avançada e úlcera ativa / Objective: To compare the results of varicose vein treatment using ultrasoundguided foam sclerotherapy versus conventional surgery in patients with venous ulcers. As a secondary outcome, we compared the incidence of complications related to the employed technique and improvements in quality of life after the procedures. Methods: A randomized and prospective study was conducted in 49 patients with active venous ulcers (C6), submitted to surgical treatment (28 limbs) or foam sclerotherapy (23 limbs). The primary outcomes analysed included healing of venous ulcer, treatment complications and improvements in quality of life. All patients completed the Aberdeen Varicose Veins Questionnaire (AVVQ), the Venous Clinical Severity score (VCSS) and Venous Disability Score (VDS). Results: The mean and standard deviation follow-up was 502 ± 220 days. Ulceration healing was observed in 100% and 91.3% of patients treated with surgery or foam sclerotherapy, respectively (P > 0.05). AVVQ, VCSS and VDS improved in both groups following treatment. There were no significant differences in AVVQ, VCSS and VDS between the two groups several months after the procedures (p = 0,45, 0.58 and 0.66, respectively; Mann-Whitney U test). Complications occurred in 14.2% and 13.0% in the surgical and foam sclerotherapy groups, respectively. Conclusion: Sclerotherapy was non-inferior to surgical treatment in the management of venous ulcers. Therefore sclerotherapy can be considered an alternative to surgical treatment, especially in high surgical risk patients presenting with advanced venous insufficiency and an active ulcer

No / To build an early warning score (EWS) based exclusively on routinely undertaken laboratory tests that might provide early discrimination of in-hospital death and could be easily implemented on paper. Using a database of combined haematology and biochemistry results for 86,472 discharged adult patients for whom the admission specialty was Medicine, we used decision tree (DT) analysis to generate a laboratory decision tree early warning score (LDT-EWS) for each gender. LDT-EWS was developed for a single set (n=3496) (Q1) and validated in 22 other discrete sets each of three months long (Q2, Q3...Q23) (total n=82,976; range of n=3428 to 4093) by testing its ability to discriminate in-hospital death using the area under the receiver-operating characteristic (AUROC) curve. The data generated slightly different models for male and female patients. The ranges of AUROC values (95% CI) for LDT-EWS with in-hospital death as the outcome for the validation sets Q2-Q23 were: 0.755 (0.727-0.783) (Q16) to 0.801 (0.776-0.826) [all patients combined, n=82,976]; 0.744 (0.704-0.784, Q16) to 0.824 (0.792-0.856, Q2) [39,591 males]; and 0.742 (0.707-0.777, Q10) to 0.826 (0.796-0.856, Q12) [43,385 females]. CONCLUSIONS: This study provides evidence that the results of commonly measured laboratory tests collected soon after hospital admission can be represented in a simple, paper-based EWS (LDT-EWS) to discriminate in-hospital mortality. We hypothesise that, with appropriate modification, it might be possible to extend the use of LDT-EWS throughout the patient's hospital stay.

<p>Тешка траума се може дефинисати на неколико различитих начина. Најчешће коришћена дефиниција укључује коришћење Injury Severity Score ( ISS скор). Ако је вредност ISS скор &gt;15, ради се о тешкој трауми. Траума је временски осетљиво стање, због тога је за збрињавање тешко повређених пацијената неопходна добра сарадња различитих нивоа здравствене заштите и здравствених стручњака различитих специјалности. У претходних неколико деценија, због сложенијег процеса лечења и великих трошкова, дошло је до потребе за што објективнијом проценом стања повређеног и исхода лечења. Циљ: Упоредити сензитивност и специфичност T-RTS скорa (Triage Revised Trauma Score), CRAMS скалe (Circulation, Respiration, Abdomen, Motor and Speech), МGAP скора (Mechanism, Glasgow coma scale, Age, and arterial Pressure) и GAP скора (Glasgow coma scale, Age, and arterial Pressure) примењених на прехоспиталном нивоу, проценити могућности прехоспитално примењених RTS, CRAMS, МGAP и GAP скорова у предикцији исхода лечења повређеног пацијента и утврдити значај појединачних фактора, одређиваних на прехоспиталном нивоу током иницијалног прегледa повређеног, за процену тежине повреде и предикцију исхода лечења повређеног. Истраживање је проспективног, опсервационог карактера. У истраживање су укључени пацијенти старији од 18 година, које су лекари Заводa за хитну медицинску помоћ Нови Сад (ЗЗХМП НС) и Службe хитне медицинске помоћи Дома здравља Бечеј (СХМП ДЗ Бечеј) збрињавали на терену након трауме, а потом их транспортовали у Ургентни центар Клиничког центра Војводине (УЦ КЦВ). На основу вредности ISS скора пацијенти су сврстани у једну од две групе: група А- пацијенти код којих је ISS скор након завршене дијагностике изнад 15- тешка траума и група Б -пацијенти код којих је након завршене дијагностике ISS скор &le;15- лака траума. У групи А је било 50, а у групи Б 257 пацијената. За граничне вредности скорова које означавају да траума није лака, највећу сензитивност у оцени тежине трауме је имао GAP скор 98,8%, а највећу специфичност MGAP скор 62%. У предвиђању исхода лечења, највећу сензитивност је имао RTS скор за предикцију 95,2%, а специфичност GAP скор и CRAMS скала 87,5%. MGAP скор, а пошто је у снажној корелацији са њим и GAP скор, мерени прехоспитално, су се издвојили као независни предиктор у оцени тежине трауме и предвиђању исхода лечења повређеног. Т- RTS скор и CRAMS скала су се издвојили као појединачни предиктори у оцени тежине трауме, али не и као независни предиктори. RTS скор за предикцију нема статистичку значајност у предвиђању исхода лечења повређеног, за разлику од CRAMS скале која има, али се није издвојила као независни предиктор исхода лечења. Осим наведених траума скорова, као независни предиктори у оцени тежине трауме издвојили су се: систолни крвни притисак, SaO2 у периферној крви мерена пулсном оксиметријом, повреда главе и врата и повреда грудног коша. За предвиђање исхода лечења повређеног само се SaO2 у периферној крви мерена пулсном оксиметријом издвојила као појединачни предиктор, али не и као независни предиктор исхода.</p> / <p>Teška trauma se može definisati na nekoliko različitih načina. Najčešće korišćena definicija uključuje korišćenje Injury Severity Score ( ISS skor). Ako je vrednost ISS skor &gt;15, radi se o teškoj traumi. Trauma je vremenski osetljivo stanje, zbog toga je za zbrinjavanje teško povređenih pacijenata neophodna dobra saradnja različitih nivoa zdravstvene zaštite i zdravstvenih stručnjaka različitih specijalnosti. U prethodnih nekoliko decenija, zbog složenijeg procesa lečenja i velikih troškova, došlo je do potrebe za što objektivnijom procenom stanja povređenog i ishoda lečenja. Cilj: Uporediti senzitivnost i specifičnost T-RTS skora (Triage Revised Trauma Score), CRAMS skale (Circulation, Respiration, Abdomen, Motor and Speech), MGAP skora (Mechanism, Glasgow coma scale, Age, and arterial Pressure) i GAP skora (Glasgow coma scale, Age, and arterial Pressure) primenjenih na prehospitalnom nivou, proceniti mogućnosti prehospitalno primenjenih RTS, CRAMS, MGAP i GAP skorova u predikciji ishoda lečenja povređenog pacijenta i utvrditi značaj pojedinačnih faktora, određivanih na prehospitalnom nivou tokom inicijalnog pregleda povređenog, za procenu težine povrede i predikciju ishoda lečenja povređenog. Istraživanje je prospektivnog, opservacionog karaktera. U istraživanje su uključeni pacijenti stariji od 18 godina, koje su lekari Zavoda za hitnu medicinsku pomoć Novi Sad (ZZHMP NS) i Službe hitne medicinske pomoći Doma zdravlja Bečej (SHMP DZ Bečej) zbrinjavali na terenu nakon traume, a potom ih transportovali u Urgentni centar Kliničkog centra Vojvodine (UC KCV). Na osnovu vrednosti ISS skora pacijenti su svrstani u jednu od dve grupe: grupa A- pacijenti kod kojih je ISS skor nakon završene dijagnostike iznad 15- teška trauma i grupa B -pacijenti kod kojih je nakon završene dijagnostike ISS skor &le;15- laka trauma. U grupi A je bilo 50, a u grupi B 257 pacijenata. Za granične vrednosti skorova koje označavaju da trauma nije laka, najveću senzitivnost u oceni težine traume je imao GAP skor 98,8%, a najveću specifičnost MGAP skor 62%. U predviđanju ishoda lečenja, najveću senzitivnost je imao RTS skor za predikciju 95,2%, a specifičnost GAP skor i CRAMS skala 87,5%. MGAP skor, a pošto je u snažnoj korelaciji sa njim i GAP skor, mereni prehospitalno, su se izdvojili kao nezavisni prediktor u oceni težine traume i predviđanju ishoda lečenja povređenog. T- RTS skor i CRAMS skala su se izdvojili kao pojedinačni prediktori u oceni težine traume, ali ne i kao nezavisni prediktori. RTS skor za predikciju nema statističku značajnost u predviđanju ishoda lečenja povređenog, za razliku od CRAMS skale koja ima, ali se nije izdvojila kao nezavisni prediktor ishoda lečenja. Osim navedenih trauma skorova, kao nezavisni prediktori u oceni težine traume izdvojili su se: sistolni krvni pritisak, SaO2 u perifernoj krvi merena pulsnom oksimetrijom, povreda glave i vrata i povreda grudnog koša. Za predviđanje ishoda lečenja povređenog samo se SaO2 u perifernoj krvi merena pulsnom oksimetrijom izdvojila kao pojedinačni prediktor, ali ne i kao nezavisni prediktor ishoda.</p> / <p>Severe trauma could be defined in several ways. The most commonly used definition includes Injury Severity Score (ISS) and severe trauma is determined if ISS &gt;15. Trauma management is a time sensitive issue and a coordination between different levels of health system and many specialists is vital in the treatment of severe trauma. In the last decades, a need for the objective evaluation of the severity of trauma and its outcome was perceived due to the complex management and treatment of trauma and its costs. Aim of the study: to compare the sensitivity and specificity between prehospital scores T-RTS (Revised Trauma Score), CRAMS (Circulation, Respiration, Abdomen, Motors, Speech), MGAP (Mechanism, Glasgow Coma Scale, Age, Arterial Pressure) and GAP (Glasgow Coma Scale, Age, Arterial Pressure), to assess the predictability of prehospital scores (RTS, CRAMS, MGAP and GAP) in the outcome of traumatized patients, to determine the significance of individual factors, initially determined during the prehospital evaluation, in evaluating the severity of trauma and the outcome of treatment. Patients enrolled into this prospective observational study were older than 18, prehospitally treated on the trauma site by the doctors of the Institute of the Emergency Medicine Novi Sad and Health Centre Bečej &ndash; Emergency Medical Service and afterward transported into the Emergency Centre Novi Sad. Based on ISS values, patients were divided into two groups: Group A &ndash; severe trauma (50 patients; ISS&gt;15) and Group B &ndash; mild trauma (257 patients; ISS&le;15). For the broder values of scores, determining the severity of trauma, GAP had the highest sensitivity (98%), while MGAP had the highest specificity (62%). RTS had the highest sensitivity in predicting the outcome (95.2%), while GAP and CRAMS had specificity of 87.5%. Prehospital MGAP score, in strong correlation with GAP, was singled out for its independent predictive value in determining the severity of trauma and its outcome. T-RTS and CRAMS stood out to be individual &ndash; but not independent &ndash; predictors in evaluating the severity of trauma. RTS was not statistically significant in predicting the outcome, in contrast with CRAMS. However, CRAMS was not singled out as an independent predictor of the outcome. In addition to the scores, independent predictors of the severity of trauma were: systolic blood pressure, arterial oxygen saturation (SaO2) by using the pulse oximeter, head, neck and thorax injuries. Only SaO2 proved to be a single &ndash; but not independent &ndash; predictor of the outcome.</p>
