Índice de recurrencia de tumor de células gigantes con curetaje y cementación / Recurrence rate of giant-cell tumor treated by curettage and cementation

OBJETIVO Identificar la tasa de recurrencia de tumor de células gigantes (TCG) en pacientes tratados con curetaje y cementación con seguimiento mínimo de tres años. MATERIALES Y METODOS Cohorte retrospectiva y observacional de pacientes con diagnóstico de TCG en estadios 1 y 2 de Enneking tratados con curetaje intralesional y cementación entre 1981 y 2011. Se registraron edad, sexo, región anatómica, y tiempo de recurrencia. Se utilizó estadística descriptiva con medidas de tendencia central y medidas de dispersión (desviación estándar) para variables cuantitativas, y porcentajes para variables cualitativas. RESULTADOS Entre 1981 y 2011, se identificaron 375 casos de TCG, de los cuales 141 (37,6%) fueron tratados con este método. El seguimiento fue de 48 a 240 meses, y la edad, de 27 9 años; 45% de los pacientes eran mujeres, y 55%, varones, con una relación mujer:hombre de 1,2:1. El hueso más afectado fue la tibia (38%), seguida del fémur (32%), del húmero (16%), y del radio (10%). En 88,6%, la resección fue curetaje intralesional, y el resto, marginal. Hubo 15,7% de casos de TCG con fractura, y recidiva en 12,7%. DISCUSIÓN Se ha demostrado que este método de tratamiento reduce el riesgo de recurrencia por los efectos adyuvantes locales de la cementación acrílica. La recurrencia ocurre en los dos primeros años de seguimiento. Sin embargo, hay autores que respaldan que el margen quirúrgico es el único factor que influencia el riesgo de recurrencia local. La extensión extraósea del TCG no es contraindicación para curetaje intralesional y adyuvante con metilmetacrilato. CONCLUSIONES Reportamos tasa una de recurrencia similar a la de la literatura, siendo un recurso factible de reconstrucción de miembros

OBJETIVE To identify the recurrence rate of giant-cell tumor (GCT) in patients treated by curetage and adjuvant therapy with polymethil metacrylate with a minimum followup of 3 years. MATERIALS AND METHODS Observational and retrospective cohort with patients with diagnoses of Enneking stages 1 and 2 GCT treated through intralesional curetage and cementation between 1981 and 2011. Age, gender, anatomic location and relapse period were recorded. The data was analyzed with measures of central tendency and dispersion (standard deviation) for the quantitative variables, percentages for the qualitative variables. RESULTS Between 1981 and 2011 375 cases of GCT were identified, 141 (36.7%) of which were treated by this method. The follow-up ranged from 48 to 240 months, the age was of 27 9 years, 45% of the patients were female, and 55%, male, with a female: male ratio of about 1.2:1. The tibia was the most frequent affected bone (38%), followed by the femur (32%), the humerus (16%), and the radius (10%). The resection thecnique was intralesional curetage in about 88.6% of the cases, and marginal resection in the remaining cases. Pathologic fracture was present in approximately 15.7%, and recurrence occurred in approximately 12.7%. DISCUSSION We demonstrated that this treatment method decreases the risk of recurrence due to the local adjuvant effects of acrylic cementation. Recurrence events occur in the first two years after resection. However, some authors defend that the surgical margin is the only factor that influences the risk of local recurrence. The extraosseus extension of GCT is not a contraindication to perform intralesional curetage or to prescribe the adjuvant treatment with polymethyl metacrylate. CONCLUSIONS We reported a recurrence rate similar to that of the literature, and this is a feasible resource for limb reconstruction

Comparison between curettage adenoidectomy and endoscopic-assisted microdebrider adenoidectomy in terms of Eustachian tube dysfunction / Comparação entre adenoidectomia por curetagem e adenoidectomia por microdebridador assistida por endoscopia, em relação à disfunção tubária

Abstract Introduction Adenoidectomy can be performed with many ways, including curettage and microdebrider endoscopic-assisted adenoidectomy. Those two techniques have advantages and disadvantages. Objective The objective of this study is to research the effects of curettage adenoidectomy and endoscopic-assisted microdebrider adenoidectomy on the tympanum pressures in pediatric patients with adenoid hypertrophy without otitis media with effusion. Methods This prospective descriptive study was performed with 65 patients who had a normal tympanic membrane and normal tympanogram and then underwent adenoidectomy or adenotonsillectomy for adenoid and tonsil hypertrophy. The subjects were randomly divided into two groups: curettage adenoidectomy group and endoscopic microdebrider-assisted adenoidectomy group. They underwent tympanometry, and the preoperative as well as 1st and 7th day postoperative values of the tympanum pressures were compared within and among the groups. Results There were 32 patients in the curettage adenoidectomy group and 33 patients in the microdebrider adenoidectomy group. Statistically significant differences were observed in the median tympanum pressure on the preoperative and 1st and 7th postoperative days for both the left and right ears with curettage adenoidectomy (p < 0.001, p < 0.001). This difference occurred on the 1st postoperative day, and the value returned to normal on the 7th day. There was no significant difference in the median tympanum pressure on the preoperative and 1st and 7th postoperative days for both the left and right ears in the microdebrider adenoidectomy group (p = 0.376, p = 0.128). Conclusion Postoperative Eustachian tube dysfunction is seen less often with the endoscopic-assisted microdebrider adenoidectomy technique than with the conventional adenoidectomy technique.

Resumo Introdução A adenoidectomia pode ser realizada de várias maneiras, inclusive por curetagem e por microdebridador, assistida por endoscopia. Essas duas técnicas têm algumas vantagens e desvantagens. Objetivo O objetivo deste estudo foi investigar os efeitos da técnica de adenoidectomia por curetagem e da adenoidectomia por microdebridador assistida por endoscopia sobre a pressão timpânica em pacientes pediátricos com hipertrofia adenoideana sem otite média com efusão. Método Estudo descritivo prospectivo feito com 65 pacientes que apresentavam membrana timpânica e timpanograma normais, que foram então submetidos à adenoidectomia ou adenotonsilectomia por hipertrofia adenoamigdaliana. Os pacientes foram divididos aleatoriamente em dois grupos: grupo adenoidectomia por curetagem e grupo adenoidectomia por microdebridador assistida por endoscópio. Todos os pacientes fizeram timpanometria e os valores das pressões do tímpano pré-operatórios e pós-operatórios no 1º e 7º dias foram comparados intragrupos e entre os grupos. Resultados Foram incluídos 32 pacientes no grupo adenoidectomia por curetagem e 33 pacientes no grupo adenoidectomia com microdebridador. Diferenças estatisticamente significantes foram observadas na mediana da diferença entre a pressão timpânica no pré-operatório e no 1º e 7º dias de pós-operatório para ambas as orelhas, direita e esquerda, na adenoidectomia por curetagem (p < 0,001, p < 0,001). Essa diferença ocorreu no 1º dia do pós-operatório e o valor retornou ao normal no 7º dia. Não houve diferença significante na mediana entre pressão timpânica no pré-operatório e no 1º e 7º dias de pós-operatório para as orelhas direita e esquerda no grupo de adenoidectomia com microdebridador (p = 0,376, p = 0,128). Conclusão A disfunção tubária no pós-operatório é observada menos frequentemente com a técnica de adenoidectomia por microdebridador assistida por endoscopia quando comparada com a técnica convencional.

Trastornos del espectro de placenta acreta / Disorders of Placenta Accreta Spectrum

RESUMEN El antecedente de cesáreas es el factor de riesgo más importante en el desarrollo de los trastornos del espectro de placenta acreta. La elevación global del indicador de cesárea ha llevado aparejado un aumento en la incidencia de estos trastornos. Sin embargo, deben considerarse entre los riesgos, otras condiciones antenatales asociadas con un daño quirúrgico menos extenso de la pared uterina, tal es el caso de los legrados. Se realiza una revisión de la literatura sobre el tema de los trastornos del espectro de placenta acreta para profundizar sobre su grave repercusión en el embarazo y se recomienda, como parte de la atención prenatal, la pesquisa de placentación acreta en toda gestante con antecedentes de legrados uterinos. La placenta acreta es casi siempre una condición enteramente iatrogénica y en lo que respecta al aborto, profesionales de la salud y paciente podríamos contribuir a la disminución de su incidencia(AU)

ABSTRACT A history of C-sections is the most important risk factor for the development of placenta accreta spectrum disorders. The global elevation of caesarean section indicator has led to increase the incidence of these disorders. However, other antenatal conditions should be considered among the risks, associated with less extensive surgical damage of the uterine wall, such as curettage. A literature review on the subject of placental accreta spectrum disorders is carried out to deepen on the serious impact on pregnancy. Screening of placenta accreta is recommended in all pregnant women with a history of uterine curettage, as part of prenatal care. Placenta accreta is generally an entirely iatrogenic condition. Health professionals and patients could contribute to the reduction of this condition incidence, in regards to abortion(AU)

Surgical treatment of axillary hyperhidrosis by suction-curettage of sweat glands

Suction curettage is a dermatologic surgery technique for the treatment of axillary hyperhidrosis, which is becoming more popular. Objective: The purpose of this study is to describe the current technique of removal of axillary sweat glands, and evaluate its efficacy and safety. Conclusion: Suction-curettage of sweat glands is a minimally invasive surgical technique that is easy to perform, safe, has high rates of success and relatively few side-effects. It is generally well tolerated by patients and requires shorter time away from daily activities, when compared with other surgical modalities.

Epidermal curettage technique (ECT) for tissue harvest from the donor area for melanocyte autologous grafting in cases of vitiligo

Vitiligo is a dermatosis requiring complex treatment. In clinically stable cases, melanocyte autologous grafting has shown good results, using different methodologies for obtaining the donor area: dermatomes, punches, blisters. However, these techniques are complex and require specific instruments. This study presents a simple technique for melanocyte harvest that has been performed in our service for more than ten years and includes epidermal curettage of the donor area, grafting of the obtained material, which was homogenized with saline or hyaluronic acid, on the achromic area, and the application of a semipermeable dressing that is removed 1 week later.

Tumor Treated by Endoscopy

BACKGROUND: This study was conducted to examine the clinical usefulness and efficacy of endoscopic curettage on benign bone tumor. METHODS: Thirty-two patients (20 men and 12 women) with benign bone tumor were included in the study. The patients were aged between five and 76 years; the mean follow-up period was 27.05 months (range, 9.6 to 39.9 months). The primary sites include simple bone cyst (9 cases), fibrous dysplasia (6 cases), enchondroma (5 cases), non-ossifying fibroma (4 cases), bone infarct (3 cases), aneurysmal bone cyst (1 case), chondroblastoma (1 case), osteoblastoma (1 case), intraosseous lipoma (1 case), and Brodie abscess (1 case). A plain radiography was performed to assess the radiological recovery. Radiological outcomes, including local recurrence and bone union, were evaluated as excellent, good, poor, and recurred. RESULTS: In our series, there were 27 cases (84.4%) of good or better outcomes, six cases (18.8%) of complications (4 local recurrence, 1 wound infection, and 1 pathologic fracture). CONCLUSIONS: Our results showed that endoscopic curettage and bone graft had a lower rate of recurrence and a higher cure rate in cases of benign bone tumor. It can, therefore, be concluded that endoscopic curettage and bone graft might be good treatment modalities for benign bone tumors.

Transpedicular Curettage and Drainage of Infective Lumbar Spondylodiscitis: Technique and Clinical Results

BACKGROUND: Infective spondylodiscitis usually occurs in patients of older age, immunocompromisation, co-morbidity, and individuals suffering from an overall poor general condition unable to undergo reconstructive anterior and posterior surgeries. Therefore, an alternative, less aggressive surgical method is needed for these select cases of infective spondylodiscitis. This retrospective clinical case series reports our novel surgical technique for the treatment of infective spondylodiscitis. METHODS: Between January 2005 and July 2011, among 48 patients who were diagnosed with pyogenic lumbar spondylodiscitis or tuberculosis lumbar spondylodiscitis, 10 patients (7 males and 3 females; 68 years and 48 to 78 years, respectively) underwent transpedicular curettage and drainage. The mean postoperative follow-up period was 29 months (range, 7 to 61 months). The pedicle screws were inserted to the adjacent healthy vertebrae in the usual manner. After insertion of pedicle screws, the drainage pedicle holes were made through pedicles of infected vertebra(e) in order to prevent possible seeding of infective emboli to the healthy vertebra, as the same instruments and utensils are used for both pedicle screws and the drainage holes. A minimum of 15,000 mL of sterilized normal saline was used for continuous irrigation through the pedicular pathways until the drained fluid looked clear. RESULTS: All patients' symptoms and inflammatory markers significantly improved clinically between postoperative 2 weeks and postoperative 3 months, and they were satisfied with their clinical results. Radiologically, all patients reached the spontaneous fusion between infected vertebrae and 3 patients had the screw pulled-out but they were clinically tolerable. CONCLUSIONS: We suggest that our method of transpedicular curettage and drainage is a useful technique in regards to the treatment of infectious spondylodiscitic patients, who could not tolerate conventional combined anterior and posterior surgery due to multiple co-morbidities, multiple level infectious lesions and poor general condition.

Canaliculite: relato de caso e conduta / Canaliculitis: case report and conduct

A canaliculite é uma infecção rara e crônica do canalículo lacrimal, cuja etiologia mais comum é o Actinomyces israelli (bactéria gram positiva, anaeróbica). Esta afecção não apresenta cura espontânea. O diagnóstico diferencial se faz com: conjuntivite crônica recorrente, blefarite e hordéolo. O tratamento definitivo é o cirúrgico (canaliculotomia), sendo realizado sob anestesia local.

The canaliculitis is a rare infection and chronicle lachrymal pathology, whose commoner etiology is Actinomyces israelli ( bacteria anaeroby positive gram). This pathology does not present cure espontany The diagnosis differential with is done: Recurring chronic conjunctivitis, blefarity and hordeoly. The definitive treatment is the surgical (canaliculotomy)), being accomplished under location anesthetizes.

Tratamento da unha encravada: comparação da taxa de cura entre a técnica de fenolização clássica e a técnica de fenolização associada à curetagem da matriz ungueal - é necessária a associação? / Treatment of ingrown nail: comparison of recurrence rates between the nail matrix phenolization classical technique and phenolization associated with nail matrix curettage - is the association necessary?

No Brasil, alguns serviços associam a curetagem da matriz ungueal à fenolização, como tentativa de aumentar a eficácia do tratamento da unha encravada. O objetivo deste trabalho foi comparar a taxa de cura entre a fenolização e a fenolização associada à curetagem da matriz. Foi realizado um estudo retrospectivo e incluídos 271 cantos encravados. Recorreram 5 por cento após a realização da fenolização, e 7,7 por cento após a fenolização com curetagem da matriz. Não houve diferença estatística entre as duas técnicas, mostrando não ser necessária a associação com a curetagem da matriz. A fenolização mostrou-se eficiente mesmo para o grau III.

Some services in Brazil combine curettage of the nail matrix with phenolization in the treatment of ingrown nails, with the objective of further increasing efficacy. The objective of this research was to compare the cure rates between the phenolization technique and phenolization associated with nail matrix curettage. A retrospective study was done which included 271 cases. There was only a 5 percent recurrence rate for the phenolization procedure, compared with 7.7 percent for combined phenolization/nail matrix curettage. There was no statistically significant difference between the two techniques, which indicated that there is no need for curettage of the nail matrix. Phenolization worked even for level III disease.

A eletrocauterização isolada como adjuvante no tratamento dos tumores ósseos benignos / Isolated cauterization as an adjuvant in the treatment of benign bone tumors

OBJETIVOS: Avaliar o papel da eletrocauterização como método adjuvante isolado na ressecção intralesional dos tumores ósseos benignos, levando em conta fatores associados à recorrência dessas lesões. MÉTODOS: Foram incluídos 47 pacientes com diagnóstico de tumores ósseos benignos que foram tratados com curetagem associada a eletrocauterização como método adjuvante. Os pacientes foram acompanhados por um tempo médio de 32,7± 19,4 meses e foi avaliada a taxa de recidiva em relação às seguintes variáveis: idade, sexo, localização do tumor, tipo histológico, estadiamento (B1, B2, B3), tamanho, tipo de material utilizado como preenchimento (PMMA ou enxerto ósseo). A taxa e o tipo de complicação pós-operatória também foram analisadas. RESULTADOS: A recidiva global foi de 19,1 por cento, havendo correlação significante do grau do tumor em relação ao tempo de recidiva (p=0,028). Não foram observados outros fatores diretamente relacionados à recidiva local. CONCLUSÃO: A eletrocauterização mostrou-se um método simples, barato e eficaz no tratamento adjuvante dos tumores ósseos benignos. Nivel de Evidência IV, serie de casos.

OBJECTIVES: To evaluate the efficacy of cauterization as a sole adjuvant method inintralesional resection of benign bone tumors, taking into account associated factors that could influence local recurrence. METHODS: 47 patients diagnosed with different benign bone tumors were included in this study, all of whom had been treated with curettage associated with cauterization as an adjuvant method. The medium follow-up was 32.7 ± 19.4 months. The recurrence rate was then evaluated in relation to age, sex, location of the tumor, histologic type, tumor grade ( B1, B2 or B3 ), and size and type of material used to fill the tumor cavity ( PMMA or autologus bone). The type and percentage of complications were also included in the analysis. RESULTS: Global recurrence was 19.1 percent. There was statistic significance relating tumor grade to time to recurrence (p=0,028). No other factors were found that directly correlated with global recurrence of the tumors. CONCLUSION: Cauterization proved to be a simple, inexpensive and effective adjuvant method for the treatment of benign bone tumors. Level of Evidence: Level IV, case series.

Preoperative and postoperative agreement of histopathological findings in cases of endometrial hyperplasia.

OBJECTIVE: To determine agreement of preoperative and postoperative histopathology of endometrial hyperplasia (EH). MATERIALS AND METHODS: Histopathology of specimens obtained by curettage and hysterectomy within 1 year was retrospectively compared by a skilled gynecological pathologist. Patients who received hormone therapy were excluded. RESULTS: Of 79 women with a preoperative diagnosis of EH, only 32 were diagnosed as EH from hysterectomy specimens. There was no endometrial cancer. The agreement between preoperative and postoperative histology did not achieve statistical significance (Kappa 0.011). Postoperative histopathology was more severe than preoperative diagnosis in 5 (6.3%) patients, including 3 preoperative diagnoses of simple hyperplasia without atypia, 1 simple hyperplasia with atypia, and 1 complex hyperplasia without atypia. CONCLUSIONS: For EH diagnosed by curettage, we can be sure of the diagnosis. However, 6.3% had more severe histology from hysterectomy specimens. Thus, repeated curettage or other investigations should be reconsidered in women with recurrent bleeding.

Analgesia con electroacupuntura en pacientes sometidas a legrados diagnóstico con enfermedades descompensadas / Electroacupuncture analgesia in female patients undergoing diagnostic curettages with decompensated diseases

Se realizó un estudio descriptivo retrospectivo que estuvo relacionado con la aplicación de la electroacupuntura en pacientes sometidas a legrados diagnóstico, con el objetivo de evaluar su efectividad. Se aplicó analgesia mediante la electroacupuntura a 201 pacientes que presentaron riesgos de contraindicaciones a la anestesia general y algunas que se decidieron a participar en el estudio de forma voluntaria. Se analizaron las variables: edad, riesgo anestésico, complicaciones transoperatorias, valoración del dolor, tipo de procedimiento realizado y evaluación del tratamiento. Se registró que el 63,1 por ciento de los casos tenían entre 41-60 años de edad, el 73,6 por ciento de los pacientes presentaron riesgo anestésico y hubo una efectividad de la analgesia mediante la electroacupuntura para el 96,1 por ciento. No refirieron dolor durante el transoperatorio el 85 por ciento de los pacientes y solo el 9,9 por ciento presentó complicaciones, predominando la hipertensión arterial. El 75,6 por ciento refirió que el método de analgesia mediante la electroacupuntura fue una alternativa muy buena(AU)

A descriptive retrospective study related to the application of electroacupuncture in female patients undergoing diagnostic curettages was conducted in order to evaluate its efectiveness. Electroacupuncture analgesia was administered to 201 patients that presented risks of contraindications to general anesthesia and to some of them that decided to participate in the study as volunteers. The following variables were analyzed: age, anaesthetic risk, transoperative complications, assessment of pain, type of procedure carried out and treatment evaluation. It was observed that 63.1 percent of the cases were between 41 and 60 years old, and that 73.6 percent of the patients presented anesthesic risk. Electroacupuncture analgesia showed an effectivity of 96.1 percent. 85 percent of the patients did not refer pain in the transoperative, and only 9.9 percent had complications, with predominance of arterial hypertension. 75.6 percent considered electroacupuncture analgesia as a good alternative(AU)

Vitiligo: analysis of grafting versus curettage alone, using melanocyte morphology and reverse transcriptase polymerase chain reaction for tyrosinase mRNA

CONTEXTO E OBJETIVO: Estudos recentes têm indicado que áreas de vitiligo contêm melanócitos inativos ou dormentes. A síntese de melanina está relacionada com a presença de tirosinase é indicadora de estado metabólico ativo. O escopo deste artigo é comparar repigmentação, distribuição epidérmica de melanócitos e detecção do RNAm de tirosinase através da reação de polimerase em cadeia por transcriptase reversa, em amostras de tecido de vitiligo, antes e após curetagem, seguido ou não por uma nova técnica de enxerto autólogo de pele. TIPO DE ESTUDO E LOCAL: Prospectivo, na Disciplina de Dermatologia da Faculdade de Medicina do ABC, Santo André. MÉTODOS: Duas áreas de vitiligo foram curetadas. Uma foi subseqüentemente enxertada com pele autóloga sacral normal, enquanto a outra não recebeu nenhum enxerto. As áreas curetadas foram examinadas após 30 dias, para avaliar o grau de repigmentação. A porcentagem de melanócitos e a presença de RNAm de tirosinase de pele normal e de pele de vitiligo (antes e após curetagem apenas e antes e após curetagem seguida de enxertia) foram comparadas. RESULTADOS: Repigmentação completa foi observada em todas as áreas enxertadas, enquanto as áreas de vitiligo apenas curetadas apresentaram repigmentação parcial. A porcentagem de melanócitos nas áreas enxertadas excederam as áreas de vitiligo não tratados (p = 0.01) e as áreas tratadas com curetagem simples (p = 0,015). RNAm de tirosinase foi negativo em 93.75 por cento das áreas não tratadas de vitiligo. Após tratamento (somente curetagem ou curetagem seguida de enxerto), todas as lesões tornaram-se positivas para RNAm de tirosinase. CONCLUSÃO: Melanócitos metabolicamente inativos ou dormentes estão provavelmente presentes dentro das áreas de vitiligo, e podem ser ativados por estímulos endógenos ou exógenos.

Evaluation of the recurrence rate of aneurysmal bone cyst after different surgical reconstructive options

A review of 20 patients with aneurysmal bone cyst involving different anatomic locations in the skeleton who were evaluated and staged according to Enneking et al., [1-5] system as 11 active benign lesions [55%] and 9 aggressive benign lesions [45%]. Meticulous curettage was achieved in 15 patients and autogenous bone grafting was applied in 11 patients, 3 of them paternal bone grafting was used and in 4 cases no grafts was applied. In 5 patients resection of the affected bony tubular segment was achieved without reconstruction in 4 of them and a fibular grafting done for the fifth. The mean age at surgery was 16 years old. Union was achieved in all the cases at an average of 9 months. As regard the complications that needs reoperations was in 4 cases of local recurrence and graft resorption necessitating re-grafting, 2 cases with nerve palsy spontaneously improved during the follow up and one case with residual coxa vara which corrected after cyst healing. The mean follow up period was 22.4 months. The functional results of the procedure were rated as excellent in 18 cases [90%], fair in one case [5%], poor in one case [5%]. The end results of the procedure are justifiable for tumor surgery provides cyst healing and ossification with sufficient biological strength and durability with a stable limb and excellent functional end result

Unusual location of eosinophilic granuloma

Frequency, presentation and postintervention prognosis of chondroblastoma

To evaluate the frequency of clinico-radiological presentation and the prognosis after treatment of chondroblastoma. Design: A descriptive, observational study. Place and Duration of Study :The study was carried out at the Department of Orthopaedic Surgery, JPMC, Karachi over the period of 16 years, January 1986 to June 2002. Methodology: Patients in teenage, presenting with signs and symptoms of a primary bone tumours, were included by retrospectively reviewing the tumour registry record. Detailed scrutiny of clinical record was carried out to analyze the clinico radiological presentation and posttreatment prognosis criteria of healing was symptom-free centripetal and homogenous ossification. Seven [1.24%] out of 563 primary bone tumour cases were chondroblastoma. The clinico-radiological presentation in the 2 out of 7 [28.57%] cases was classical, 2 simulated osteomyelitis and other 3 as chondromyxoid fibroma, aneurysmal bone cyst and giant cell tumour. Lesions were treated with curettage and bone grafting. One patient [14.28%] developed recurrence within 2 years after curettage and healed after re-curettage and bone grafting. Five out of 7 [71,42%] tumours showed good response and 2 out of 7[28.57%] showed satisfactory response. Chondroblastoma is very rare benign primary bone tumour with high local recurrence rate. The lesions confined to epiphysis of weight-bearing bone present early with symptoms of mild arthritis. Lesions in non-weight -bearing bones often present late and simulates epiphysio-metaphyseal tumours. Lesions heals with centripetal healing and need more than 2 years follow-up to achieve recurrence-free healing

Comparación entre anestesia general endovenosa con ketalar, utilizando premedicación y sin ella / Comparison between general endovenous anesthesia with ketalar, using premedication and without it

Se realizó un estudio descriptivo y transversal de 50 pacientes atendidas en el servicio de legrados del Hospital General Docente "Alberto Fernández Montes de Oca", del municipio San Luis, en el período comprendido desde abril hasta mayo de 1998, con el fin de determinar las ventajas del ketalar como anestesia general endovenosa, a través de la premedicación con difenhidramina y sin ella. Se determinó la aparición de complicaciones en cada uno de los grupos, así como también el costo de los medicamentos, donde se comprobó que éstos se reducen notablemente con la premedicación, lo que significa un ahorro para la unidad y para el Sistema Nacional de Salud(AU)

A descriptive and cross-sectional study of 50 patients cared at the service of curettages of "Alberto Fernández Montes de Oca" General Teaching Hospital, of San Luis municipality, was conducted in the period comprised from April to May of 1998 so as to determine the advantages of ketalar as a general endovenous anesthesia, through the premedication with diphenhydramine and without it. The appearance of complications in each of the groups was determined, as well as the medicines cost and it was checked that the costo can be remarkably reduced with the premedication which means a saving for the unit and for the National Health System(AU)
