ABSTRACT

RESUMEN Introducción: El estándar para inducción de madurez pulmonar en fetos con riesgo de nacer prematuramente es la administración de 12 mg de betametasona acetato/fosfato por dos veces espaciada cada 24 horas. El uso establecido en algunos hospitales públicos en Chile es con dos dosis de 12 mg betametasona fosfato aunque no existen estudios publicados sólo con betametasona fosfato sobre la incidencia de Síndrome de Distress Respiratorio (SDR). Objetivo: Evaluar efecto de betametasona en su forma fosfato como tratamiento antenatal para inducción de madurez fetal pulmonar en la incidencia SDR debido a membrana hialina en prematuros menores de 34 semanas de edad gestacional. Comparar el efecto de betametasona fosfato con el efecto publicado de betametasona acetato/fosfato. Material y método: Análisis de incidencia de SDR en prematuros nacidos en Hospital Padre Hurtado entre 24+0 y 34+0 semanas que recibieron betametasona fosfato para madurez pulmonar y aquellos que no la recibieron. Resultados: De 1.265 neonatos estudiados, 722 completaron dos dosis (57,5%); 436 sólo una dosis (34,5%) y 107 (8,5%) no recibieron corticoides antenatales. La incidencia de SDR debido a membrana hialina en el grupo con dos dosis fue 8,7%, una dosis 25,3% y 32,7% en los no tratados (p<0,001). Para SDR severo las incidencias fueron 6,7%, 12,6% y 16,8% respectivamente (p<0,001). Conclusiones: Inducción de madurez fetal pulmonar con betametasona fosfato en dos dosis de 12 mg IM separadas por 24 horas otorga una reducción significativa de incidencia de SDR semejante a la publicada con betametasona acetato/fosfato en iguales dosis.


ABSTRACT The standard for induction of lung maturity in fetuses at risk of being born prematurely is the administration of 12 mg of betamethasone acetate/phosphate two doses separated by 24 hours. The established use in some public hospitals in Chile is with two doses of 12 mg betamethasone phosphate although there are no studies published with betamethasone phosphate alone on the incidence of respiratory distress syndrome (RDS). Objective: To evaluate the effect of betamethasone in its phosphate form as antenatal treatment for the induction of fetal lung maturity in the incidence of RDS due to hyaline membrane in preterm infants less than 34 weeks of gestational age. To compare the effect of betamethasone phosphate with the published effect of betamethasone acetate/phosphate. Material and method: Analysis of the incidence of RDS in preterm infants born at Hospital Padre Hurtado between 24 + 0 and 34 + 0 weeks who received betamethasone phosphate for lung maturity and those who did not receive it. Results: Of 1,265 infants studied, 722 completed two doses (57.5%); 436 only one dose (34.5%) and 107 (8.5%) did not receive antenatal corticosteroids. The incidence of RDS due to hyaline membrane in the group with two doses was 8.7%, one dose 25.3% and 32.7% in the untreated ones (p <0.001). For severe RDS, incidences were 6.7%, 12.6% and 16.8% respectively (p <0.001). Conclusions: Induction of fetal lung maturity with betamethasone phosphate in two doses of 12 mg IM separated by 24 hours gives a significant reduction in the incidence of RDS similar to that published with betamethasone acetate/phosphate in equal doses.

ABSTRACT

Objetivo: Investigar os efeitos da administração da corticoterapia antenatal sobre a hemodinâmica fetal, utilizando uma análise longitudinal e quantitativa das curvas de velocidade de fluxo do Doppler das artérias umbilical e cerebral média. Metodologia: Este estudo utilizou revisão de prontuários e incluiu 30 fetos que estavam sob o risco de parto prematuro. Vinte e oito gestantes foram tratadas com betametasona, visando o amadurecimento pulmonar fetal. Os exames Dopplervelocimétricos das artérias umbilical e cerebral média foram realizados uma vez antes da corticoterapia e depois da administração do medicamento, totalizando três ou oito observações ao longo do tempo. Optamos pelo emprego do modelo linear hierárquico sob abordagem Bayesiana. Resultados: Na análise da artéria umbilical, observamos diminuição significativa do índice de pulsatilidade após uso da corticoterapia. Porém, não foi observada mudança significativa no índice de pulsatilidade da artéria cerebral média, independente da idade gestacional e do diagnóstico de pré-eclâmpsia. Concluímos que o corticoide antenatal induz mudanças na hemodinâmica fetal, sendo observada a redução significativa no índice de pulsatilidade da artéria umbilical, sem alterar a vascularização cerebral. Apesar do resultado, não é possível afirmar se este achado causado pela administração da betametasona antenatal tem efeito benéfico para o prognóstico fetal.

ABSTRACT

Abstract Introduction: A combination of antihistamines and oral corticosteroids is often used to treat acute symptoms of allergic rhinitis. Objective: To evaluate safety and efficacy of desloratadine plus prednisolone in the treatment of acute symptoms of children (2-12 years) with allergic rhinitis, and to compare it to dexchlorpheniramine plus betamethasone. Methods: Children with moderate/severe persistent allergic rhinitis and symptomatic (nasal symptoms score [0-12] ≥ 6) were allocated in a double-blind, randomized fashion to receive dexchlorpheniramine plus betamethasone (n = 105; three daily doses) or desloratadine plus prednisolone (n = 105; single dose followed by two of placebo) for 7 days. At the beginning and end of the evaluation, the following were obtained: nasal symptoms score, extra nasal symptoms score, peak nasal inspiratory flow, blood biochemistry, and electrocardiogram. Ninety-six children of the dexchlorpheniramine plus betamethasone group and 98 of the desloratadine plus prednisolone group completed the protocol. Results: The two groups were similar regarding initial and final nasal symptoms scores, extra nasal symptoms scores and peak nasal inspiratory flow. A drop of 76.4% and 79.1% for nasal symptoms score, 86.0% and 79.2% for extra nasal symptoms score, as well as an increase of 25.2% and 24.3% for peak nasal inspiratory flow occurred for those treated with desloratadine plus prednisolone and dexchlorpheniramine plus betamethasone, respectively. There were no significant changes in blood chemistry. Sinus tachycardia was the most frequent electrocardiogram change, but with no clinical significance. Drowsiness was reported significantly more often among those of dexchlorpheniramine plus betamethasone group (17.14% × 8.57%, respectively). Conclusion: The desloratadine plus prednisolone combination was able to effectively control acute symptoms of rhinitis in children, improving symptoms and nasal function. Compared to the dexchlorpheniramine plus betamethasone combination, it showed similar clinical action, but with a lower incidence of adverse events and higher dosing convenience.


Resumo Introdução: A associação entre anti-histamínicos e corticosteroides orais é frequentemente empregada no tratamento de sintomas agudos de rinite alérgica. Objetivo: Avaliar a segurança e eficácia da associação desloratadina + prednisolona no tratamento de sintomas agudos de crianças (2-12 anos) com rinite alérgica e compará-las com as da associação dexclorfeniramina + betametasona. Método: Crianças com rinite alérgica persistente moderada/grave e sintomáticas (escore de sintomas nasais [0-12] ≥ 6) foram alocadas de modo duplo-cego e randômico para receber dexclorfeniramina + betametasona (n = 105; três doses diárias) ou desloratadina + prednisolona (n = 105; dose única seguida por duas de placebo) por 7 dias. No início e no fim da avaliação foram obtidos: escore de sintomas nasais, escore de sintomas extranasais, pico de fluxo inspiratório nasal, bioquímica sanguínea e eletrocardiograma. Do total, 96 crianças do grupo dexclorfeniramina + betametasona e 98 do grupo desloratadina + prednisolona concluíram o protocolo. Resultados: Os dois grupos foram iguais com relação ao escore de sintomas nasais, escore de sintomas nasais extranasais e pico de fluxo inspiratório nasal iniciais e finais. Observou-se queda de 76,4% e 79,1% nos escores para escore de sintomas nasais, de 86,0% e 79,2% para escore de sintomas extranasais, assim como incremento de 25,2% e de 24,3% para o pico de fluxo inspiratório nasal para os grupos desloratadina + prednisolona e dexclorfeniramina + betametasona, respectivamente. Não houve alterações significativas da bioquímica sanguínea. Taquicardia sinusal foi a alteração do eletrocardiograma mais encontrada, mas sem significância clínica. Sonolência foi significantemente mais referida entre os tratados com dexclorfeniramina + betametasona do que entre os desloratadina + prednisolona (8,57% × 17,14%, respectivamente). Conclusão: A associação desloratadina + prednisolona foi capaz de controlar efetivamente os sintomas agudos de rinite em crianças, melhorou sintomas e a função nasal. Na comparação com a associação dexclorfeniramina + betametasona, demonstrou ação clínica semelhante, mas com menor incidência de eventos adversos e maior comodidade posológica.

ABSTRACT

Tenosynovitis is the inflammation of the tendon and synovial sheath. It is commonly affects hands and wrist. The etiology may be infectious or inflammatory. In patients with Systemic Lupus Erythematosus (SLE) the periarticular and tendinous commitment is frequent. Intra-articular corticosteroids (CO) are effective as adjuvant of the systemic therapy. Complications of use are infrequent. The case of a female patient is presented, 32 years old, with SLE and chronic renal failure secondary to lupus nephritis, chronic user of oral CO. She is infiltrates with intra-articular deposit betamethasone in metacarpal-phalangeal (MCP), because of articular edema. Twelve days later evolves with Compartment Syndrome (SC). Fasciotomy show findings compatible with chemical synovitis by betamethasone crystals. Currently there are quite few reports in the literature of CS with presentation in fingers. The diagnosis is mainly clinical. The common use of intra-articular CO is not without risk and should be planned and diagnosed early...


Tenosinovitis es la inflamación del tendón y vaina sinovial. Es más frecuente en manos y muñecas. Su etiología es infecciosa o inflamatoria. En pacientes con Lupus Eritematoso Sistémico (LES) el compromiso periarticular y tendíneo es frecuente. Los corticoides (CO) intraarticulares son efectivos como adyuvante de terapia sistémica. Las complicaciones de su uso son infrecuentes. Se presenta el caso de paciente sexo femenino, 32 años, con LES e insuficiencia renal crónica secundaria a nefropatía lúpica, usuaria de CO orales. Por edema articular se le infiltra betametasona de depósito intraarticular en metacarpo-falángica (MCF). Evoluciona doce días después con Síndrome Compartimental (SC). Durante la fasciotomía se evidencian hallazgos compatibles con sinovitis química por cristales de betametasona. Existe escaso reporte en la literatura de SC en dedos de la mano. El diagnóstico es principalmente clínico. El uso común de CO intraarticulares no está exento de riesgos y deben ser previstos y diagnosticados precozmente...

ABSTRACT

Lobate GM Neo, 15 mg is a triple drug combination of a steroid clobetasol with anti-fungal miconazole and antibacterial neomycin in treatment of Eczematous disorders associated with underlying Tinea or Yeast Infections. Aims and Objectives: The study was designed to evaluate the efficacy, safety and tolerability of a combinations of clobetasol, neomycin and miconazole (Group A) versus betamethasone, clotrimazole, neomycin (Group B) versus betamethasone, gentamicin, miconazole (Group C) in subjects with any type of eczematous disorder associated with underlying tinea or yeast infection. Materials and Methods: This was an open label, parallel group, randomized comparative study. The primary endpoint analyzed was improvement in clinical score from baseline at the end of day 7 and other primary endpoint like hyperpigmentation were analyzed by the visual analogue scale of 1 to 10 at the end of day 7. Results: Thirty-six subjects were randomized to three groups. The clinical score showed a significant reduction from baseline at the end of day 7 in all the groups, i.e. 82.9%, 81.3% and 85.6% in Group A, B and C respectively. However, the difference between the groups were not statistically significant. Mean hyper pigmentation score showed significant decrease of 82.9% in Group A, 81.6% in Group B and 92.2% in Group C from baseline at the end of day 7. Conclusion: The triple combination of antifungal, antibacterial and potent steroid was found to be efficacious, safe and tolerable in reducing signs and symptoms (scaling, inflammation, burning and itching) of eczematous disorder associated with underlying tinea/yeast infection.

ABSTRACT

OBJETIVO: Avaliar a associação entre o uso materno antenatal de corticosteroide e os níveis sanguíneos de intermediários reativos de oxigênio (ROI), glutationa reduzida (GR) e interleucina-6 (IL-6) em recém-nascidos pré-termo de muito baixo peso ao nascer. MÉTODOS: Estudo de coorte. A dosagem foi feita em sangue de cordão umbilical. A dosagem de ROI por granulócitos foi realizada por citometria de fluxo nos estados basal e estimulado; a GR, por espectrofotometria; e a IL-6, por enzyme-linked immunosorbent assay. Foram considerados dois grupos em relação ao uso de corticosteroide (betametasona) antenatal: uso ou não da medicação; e, se presente, se foi de modo completo ou parcial. Variáveis maternas e neonatais foram consideradas para efeito de comparação dos grupos. As variáveis categóricas foram comparadas usando os testes do qui-quadrado ou de Fischer, e as comparações dos valores dos marcadores sanguíneos foram feitas usando-se o teste de Mann-Whitney. RESULTADOS: Os grupos de corticoterapia foram comparáveis em relação às variáveis maternas e neonatais, exceto a ocorrência de parto vaginal, o qual foi associado significativamente à ausência de uso de corticosteroide antenatal. Os valores de ROI, GR e IL-6 não se mostraram diferentes quando se avaliou a presença ou ausência da administração de esteroide; porém, quando o ciclo se fez de modo completo, encontraram-se menores medianas de ROI e IL-6. CONCLUSÃO: A administração de ciclo completo de betametasona à mãe exerceu um efeito supressor sobre a produção basal de ROI e de IL-6 em recém-nascidos pré-termo de muito baixo peso.


OBJECTIVE: To investigate the association between antenatal maternal corticosteroid administration and blood levels of reactive oxygen intermediates (ROI), reduced glutathione (GR) and interleukin-6 (IL-6) in preterm, very low birth weight infants. METHODS: This was a cohort study in which cord blood samples were used for the following tests: baseline and stimulated granulocyte ROI were measured by flow cytometry; GR was assayed by spectrophotometry; and IL-6 by enzyme-linked immunosorbent assay. Two different comparative analyses of antenatal corticosteroid (betamethasone) were conducted: the first compared administration against no administration and the second compared mothers who received the complete cycle with those given only a partial antenatal corticosteroid cycle. Maternal and neonatal variables were analyzed in order to compare groups. Categorical variables were compared using the chi-square or Fischer tests, and blood marker test results were compared using the Mann-Whitney test. RESULTS: The different corticoid therapy groups were similar in terms of all of the maternal and neonatal variables with the exception of vaginal delivery, which was significantly associated with not receiving antenatal corticosteroid. The results for ROI, GR and IL-6 did not differ when the comparison was based on simple presence or absence of administration of the steroid. However, when the complete cycle was compared against incomplete administration, median ROI and IL-6 were lower among those given the complete cycle. CONCLUSION: Administration of the complete cycle of betamethasone to the mother had a suppressive effect on baseline ROI and IL-6 production in very low birth weight preterm newborn infants.

ABSTRACT

Extraction of third molars is the most common surgical procedure performed in oral surgery on a daily basis and, despite surgical skills and expertise, complications may occur. Complications observed during or after third molar removal may include pain, swelling, bleeding, infection, sinus perforation and nerve damage. Fortunately, with a proper management and a good surgical technique, the incidence of such events is low. Subcutaneous emphysema associated with dental extraction occurs when the air from the high-speed dental handpiece is forced into the soft tissue through the reflected flap and invades the adjacent tissues, leading to swelling, crepitus on palpation and occasionally spreading through the tissue spaces of the fascial planes. Although rare, iatrogenic subcutaneous emphysema can have serious and potentially life-threatening consequences. Care should be taken when using air-driven handpieces. The access of air into the facial tissues is not limited to tooth extractions, but may also occur through other portals of entrance, such as endodontically treated teeth, periodontium and lacerations of intraoral soft tissues. When subcutaneous emphysema occurs, it must be quickly diagnosed and properly managed to reduce the risk of further complications. This report presents a case of subcutaneous emphysema occurred during extraction of a mandibular third molar extraction with the use of an air turbine handpiece. Case management is described and issues relative to the diagnosis and prevention of this surgical complication are discussed.


A extração de terceiros molares é o procedimento cirúrgico mais comum na prática diária em cirurgia oral, e complicações podem ocorrer a despeito da habilidade e experiência do cirurgião. Complicações observadas durante ou após extração de terceiros molares podem incluir dor, edema, sangramento, infecção, perfuração de seio e dano nervoso. Felizmente, a incidência de tais eventos é baixa quando se emprega conduta adequada e boa técnica cirúrgica. O enfisema subcutâneo associado à extração dentária ocorre quando o ar da turbina de alta rotação é forçado para dentro dos tecidos moles através de um retalho rebatido e invade os tecidos adjacentes, causando edema, crepitação à palpação, e eventualmente espalhando-se pelos espaços teciduais dos planos fasciais. Embora seja raro, o enfisema subcutâneo iatrogênico pode ter conseqüências sérias e com risco de morte. É necessário ter cuidado com o uso de turbinas de alta rotação durante a realização de procedimentos cirúrgicos orais. A penetração de ar nos tecidos faciais não está limitada às extrações dentárias, e pode ocorrer também por outras vias de acesso, tais como dentes tratados endodonticamente, periodonto e lacerações de tecidos moles intraorais. Quando ocorre, o enfisema subcutâneo deve ser diagnosticado rapidamente e tratado adequadamente para diminuir o risco de outras complicações. Este relato apresenta um caso de enfisema subcutâneo ocorrido durante a extração de um terceiro molar inferior com emprego de turbina de alta rotação. O manejo do caso é descrito e os aspectos relacionados ao diagnóstico e à prevenção desta complicação cirúrgica são discutidos.

ABSTRACT

Purpose: To compare the efficacy and costs of circumcision versus topical treatment using a prospective pharmacoeconomic protocol. Materials and methods: We treated 59 patients (3-10 years of age) randomized into two groups: 29 underwent an 8-week course of topical treatment with 0.2 percent betamethasone-hyaluronidase cream twice a day; and 30 underwent circumcision. Topical treatment success was defined as complete exposure of the glans. In cases of treatment failure, circumcision was performed and its cost imputed to that of the initial treatment. The pharmacoeconomic aspects were defined according to the Brazilian National Public Health System database and the Brazilian Community Pharmacies Index. Results: The two groups were statistically similar for all clinical parameters evaluated. Topical treatment resulted in complete exposure of the glans in 52 percent of the patients. Topical treatment was associated with preputial pain and hyperemia. However, treatment suspension was unnecessary. Minor complications were observed in 16.6 percent of the surgical group patients. The mean cost per patient was US$ 53.70 and US$ 125.20, respectively, for topical steroid treatment (including the costs related to treatment failure) and circumcision. The total costs were US$ 2,825.32 and US$ 3,885.73 for topical treatment and circumcision, respectively. Conclusions: Topical treatment of phimosis can reduce costs by 27.3 percent in comparison with circumcision. Therefore, topical treatment of phimosis should be considered prior to the decision to perform surgery.

ABSTRACT

OBJECTIVE: This study investigated the pulpal effect of topically applied betamethasone to the dentin of rat molars in the vascular phase of inflammation. MATERIAL AND METHODS: Deep cavities were prepared on the occlusal face of the maxillary right and left 1st molars with non-refrigerated inverted-cone steel burs at low speed. Three groups were formed: Group I was composed of right 1st molars; Group II was composed of left 1st molars that received the application of a drop of betamethasone on dentin surface for 5 min; and Group III (control) was composed of right 2nd molars that received no cavity preparation or betamethasone application. Changes in the vascular characteristics of the pulp tissue were checked by calculating the pulp vascular area in relation to its total area and the number of blood vessels per unit area. Data were subjected to ANOVA and Tukey's test (?=0.05). RESULTS: Group I presented a significantly larger number of vessels (p<0.05) than Group II. Regarding the vascular/total area ratio ( percent), Group I presented statistically significantly higher values (p=0.01) than Groups II and III. CONCLUSION: Betamethasone applied on the dentin of rat teeth proved to reduce the vascular phase of pulp inflammation regarding vessel diameter and number of blood vessels.

ABSTRACT

OBJETIVO: Analisar os efeitos da injeção repetida de betametasona na concentração de proteoglicanos da cartilagem articular do joelhos normais de coelhos californianos de ambos os sexos. MÉTODOS: Os animais foram randomizados em oito grupos de dez animais cada. Três grupos controle (injeção ou não de solução salina isotônica) e cinco grupos de estudo - doses terapêuticas, repetidas ou não, de betametasona injetadas no joelho direito de cada coelho, com intervalos semanais. Após oito dias da última injeção prevista, cortes histológicos da cartilagem das áreas de apoio dos platôs tibiais foram corados com hematoxilina e eosina para análise por microscopia óptica, e com safranina O para a pesquisa da quantidade de proteoglicanos. A intensidade da coloração da safranina O foi quantificada em aparelho de histomorfometria, composto por microscópio Olympus BX 50 e microcomputador com software Image Pro-plus 4.5Ò. RESULTADOS: Não houve diferenças nos animais que tiveram seus joelhos injetados com betametasona uma, duas e quatro vezes quando comparados com os grupos controle. Nos animais que receberam seis e oito aplicações a intensidade da coloração com safranina O reduziu-se significativamente (p < 0,05) quando comparada tanto com grupos controle quanto com os outros de estudo. CONCLUSÃO: Foi possível demonstrar redução da concentração de proteoglicanos na matriz cartilaginosa articular dependente do efeito deletério cumulativo das repetidas injeções intra-articulares de betametasona.


OBJECTIVE: To study the effects of repeated injections of betamethasone on proteoglycan concentration in the articular cartilage of normal knees of Californian rabbits of both sexes. METHODS: Eighty animals were randomly divided into eight groups of ten animals each. Three control groups (saline solution injected or not) and five study groups - therapeutical doses, repeated or not, of betamethasone injected into the right knee of each animal at weekly intervals. After eight days from the last injection, sections of articular cartilage from tibial plateaus collected from weight-bearing surfaces were stained with hematoxylin and eosin for light microscopy analysis and with safranin O for the proteoglycan content assay. The staining intensity of safranin O was quantified by histomorphometry using an Olympus BX 50 microscope and a microcomputer with the Image Pro-plus 4.5Ò software. RESULTS: Animals receiving one, two and four betamethasone injections showed no differences when compared to normal controls. Animals receiving six and eight injections had a significant decrease in safranin O staining intensity (p < 0.05) as compared to the control groups and the other study groups. CONCLUSION: A decrease in the concentration of articular cartilage proteoglycans dependent on repeated betamethasone injection was effectively demonstrated.

ABSTRACT

OBJECTIVES: This study compared the beneficial and adverse neonatal effects of a single versus repeated courses of antenatal betamethasone. SETTING: Tertiary care hospital DESIGN: Open labeled, randomized controlled trial. PARTICIPANTS: Pregnant women (26-33 weeks) at risk of preterm delivery, who received one course of antenatal betamethasone and remained undelivered for 7 days.Those with uncertain gestation, major malformations and frank chorioamnionitis were excluded. INTERVENTIONS: Subjects were randomized to receive weekly antenatal betamethasone until 34 weeks or no further betamethasone. OUTCOME MEASURES: Primary: incidence of severe respiratory distress syndrome (RDS). Secondary: incidence of non-severe RDS and other neonatal morbidity; birth weight, length and occipito-frontal circumference (OFC); and, development and growth at 6 mo corrected age. RESULTS: 38 subjects were allocated to each group. Severe RDS was similar in multiple and single course groups (7% vs. 3% respectively, P=0.34), as was incidence of other morbidity. Composite outcome of RDS and or death within 28 days tended to be less in multiple course group (P=0.07). Birth anthropometry was similar in the 2 groups. At 6 mo corrected age (n=44), weight and length were significantly lower in multiple course group (p=0.003 and P=0.007, respectively), whereas OFC was not different (P=0.1). There were no differences vis a vis neurodevelopmental outcomes. CONCLUSIONS: A single course of antenatal betamethasone was as efficacious as multiple courses, with respect to prevention of neonatal morbidity. Multiple antenatal betamethasone courses have long-term adverse effects on infant weight and length growth, but not on OFC and neurodevelopment.

ABSTRACT

BACKGROUND: If administered properly, dexamethasone cyclophosphamide pulse (DCP) therapy has the potential to effect lifelong recovery from pemphigus. AIMS: The objective of this paper is to highlight various parameters of DCP therapy and also, to report the effects of a few modifications in the regimen. METHODS: An analysis of 123 patients treated with the DCP/DP regimen over a period of five years (1998 to 2002) is presented here. Seventeen patients who did not start/continue the treatment and three patients who died during the treatment have been excluded from the analysis. Twenty patients who had not yet started families were given only dexamethasone pulses (DPs) while 103 patients received DCPs. Low dose (50 mg/day) cyclophosphamide was used as in the standard regimen. The three modifications introduced into the regimen were: (1) an additional daily dose of oral betamethasone sufficient to control the disease activity during phase I, which was progressively tapered off completely as the patient recovered, (2) use of systemic antibiotics if the patient had skin lesions, and oral anti-candida drugs if the patient had oral ulcers until complete healing, and (3) insistence on thorough cleaning of the skin and scalp with a normal soap and shampoo, and proper maintenance of oral hygiene in spite of skin/mucosal lesions. The regimen consisted of DCP/DP repeated in exactly 28-day cycles, along with 50 mg cyclophosphamide per day, insistence on completing the treatment and avoiding irregular pulses in all patients. The number of DCPs/DPs during phase I varied in different patients depending upon the dose of betamethasone used and the rate of recovery, but phase II (nine DCPs/DPs in exactly 28-day cycles along with 50 mg cyclophosphamide per day) and phase III (only 50 mg cyclophosphamide per day) was fixed at nine months each. This was followed by posttreatment follow-up (phase IV). RESULTS: At present, all the patients are in complete remission. The confirmed period of posttreatment, disease-free follow-up period has already been more than five years in 62 patients, 3-5 years in 41 patients, 2-3 years in three patients and less than two years in six patients. Eight DCP patients and three DP patients developed a relapse (the relapse rates thus being 7.7 and 15% respectively) and received a second course of pulse therapy. They are also in remission at present. The duration of phase I was three months in 62 patients, 4-5 months in 28 patients, 6-9 months in 13, 10-12 months in nine patients and more than 12 months in 11 patients. The maximum daily dose of betamethasone used in these patients was nil in 17 patients, 1-2 mg in 85, 3-4 mg in 16, and> 4 mg in five patients. CONCLUSIONS: The modifications employed in this study could ensure the cure of all pemphigus patients by using DCP therapy administered at a private clinic.

ABSTRACT

PURPOSE: To determinate the potential clinical and histological changes due the injection of betamethasone, when administered into the canine intrathecal space. METHODS: Twenty one animals were included in a random and blind manner in the study. After general anesthesia, intrathecal puncture was performed and 1 ml of the random solution was injected. The G1 dogs received 0.9 percent saline solution, the G2 dogs received 1.75 mg betamethasone and the G3 dogs received 3.5 mg of betamethasone. The animals were clinically evaluated for 21 days and then sacrificed. The lumbar and sacral portions of the spinal cord were removed for light microscopy histological analyses. RESULTS: No clinical changes were observed in any of the animals included in this study. No histological changes were observed in G1 animals. Inflammatory infiltration was observed in two dogs, one in G2, another in G3. Hemorrhage and necrosis were also seen in the G2 dog which inflammatory infiltration was detected. In other two dogs, one from G2 and another from G3, there was discreet fibrosis and thickness of the arachnoid layer which was focal in one and diffuse in the other. CONCLUSION: Intrathecal administration of betamethasone caused histological changes in the spinal cord and meninges in some of the dogs involved in this study.


OBJETIVO: Determinar possíveis alterações clínicas e histológicas determinadas pela administração da betametasona no espaço subaracnóideo de cães. MÉTODOS: Vinte e um cães foram incluídos no estudo de forma aleatória e encoberta. Depois de anestesiados, os cães foram submetidos a punção subaracóidea com injeção de 1 ml da solução sorteada. Os animais receberam solução salina 0,9 por cento em G1, betametasona na dose de 1,75 mg em G2 e betametasona na dose de 3,5 mg em G3. Todos os animais foram mantidos em observação clínica por 21 dias, sendo posteriormente sacrificados. Porções da medula espinhal e sacral foram removidas para análise histológica por microscopia óptica. RESULTADOS: Não foram detectadas alterações clínicas em quaisquer dos animais incluídos no estudo. Da mesma forma, nenhum animal do G1 apresentou alterações histológicas. Infiltração inflamatória foi observada em dois cães, um do G2 e outro e G3. No cão do G2 onde a infiltração inflamatória foi observada ocorreu, conjuntamente, hemorragia e necrose. Em dois cães, um de G2 e outro de G3, observou-se discreta fibrose e espessamento da aracnóide, sendo focal em um e difusa no outro. CONCLUSÃO: A administração subaracnóidea de betametasona determinou alterações histológicas em medula e meninges de alguns dos cães envolvidos no estudo.

ABSTRACT

BACKGROUND: Although acute radiation dermatitis (ARD) is a common side-effect of radiotherapy (RT), currently there is no general consensus about its prevention or treatment of choice. AIMS: The purpose of this study was to investigate whether prophylactic use of topical betamethasone 0.1% can prevent ARD caused by chest wall irradiation. METHODS: Fifty-one patients who underwent modified radical mastectomy for breast cancer and were going to receive RT, were randomly assigned to receive topical betamethasone 0.1%, petrolatum or none during RT. The frequency and severity of ARD (measured using Radiation Therapy Oncology Group acute radiation morbidity scoring criteria) were recorded at the end of each week during RT and two weeks after its completion. Clinical outcomes were analyzed by relevant statistical methods. RESULTS: All patients developed some degree of ARD, the frequency and severity of which increased with time and reached the maximum at the end of the seventh week for all groups. Patients receiving betamethasone had less severe ARD than the other two groups throughout the course of the study, but this difference was significant only at the end of the third week (p = 0.027). No significant difference was observed between the petrolatum and control arms. CONCLUSION: Prophylactic and ongoing use of topical betamethasone 0.1% during chest wall RT for breast cancer delays occurrence of ARD but does not prevent it. Petrolatum has no effect on the prevention of ARD in these patients.

ABSTRACT

BACKGROUND: Alopecia areata is a recurrent, nonscarring type of hair loss. Different modalities of treatment have been used to induce hair re-growth. AIMS: To determine the efficacy of topical garlic gel in the treatment of alopecia areata. METHODS: Patients were randomly divided into two groups of garlic gel and placebo. The two groups were advised to follow the treatment twice daily, for three months. Both groups received topical application of corticosteroid (betamethasone cream 0.1% in isopropyl alcohol) twice daily. Baseline demographic characteristics and the size of patches, total number of grown hair and number of terminal hair at the end of each month were recorded. Effectiveness was assessed by scoring the results. Statistical analysis was done by means of chi-square and t test. RESULTS: Forty patients met the inclusion criteria and enrolled for the study. The first group (garlic treated) consisted of 20 patients (12 males, 60% and eight females, 40%). The second group (control) consisted of 20 patients (10 males, 50% and 10 females, 50%). At the end of the treatment, good and moderate responses were observed in 19 (95%) and one (5%) patients of the case group respectively, which was significantly better than the control group (P = 0.001). No complication was observed in the patients under study. CONCLUSION: The present study showed that the use of garlic gel significantly added to the therapeutic efficacy of topical betamethasone valerate in alopecia areata and that it can be an effective adjunctive topical therapy for alopecia areata.

ABSTRACT

Tracheal intubation for general anesthesia often leads to traumatization of the airway mucosa resulting in postoperative sore throat, hoarseness and cough. This study was undertaken to determine the effects of betamethasone gel in reducing these complications. One hundred patients [ASA I-II] to undergo endotracheal intubation, were randomly divided equally into two groups; 50 Case [Group A]. 50 Control [Group B]. The tracheal tubes for Case Group A were lubricated with 0.05% betamethasone gel and for the Control Group B with KY gel. Patients were interviewed at end of procedures and 1 and 24 hour after extubation. The incidence and severity of sore throat, hoarseness and cough, 1 and 24 hours postoperatively was reduced significantly in Case Group A. Betamethasone gel, when was used for lubrication of endotracheal tubes pre-operatively, was shown to be effective in decreasing postoperative sore throat, hoarseness, and cough

ABSTRACT

Objetivo: Comparar el porcentaje de mejoría clínica entre aceponato de metilprednisolona versus dipropionato de betametasona tópicos, en niños con prepucio no retráctil. Material y métodos: De agosto del 2001 a noviembre de 2002 se realizó un estudio clínico, doble ciego y controlado en 34 niños con diagnóstico de prepucio no retráctil. Los niños fueron asignados al azar en los siguientes grupos de tratamiento tópico: grupo A; aceponato de metilprednisolona 0.1% y grupo B; dipropionato de betametasona a 0.05%. Resultados: De los 34 pacientes analizados se obtuvo mejoría en 88.2% (n = 15) del grupo A y 76.4% (n = 13) del grupo B, sin embargo, no hubo diferencia significativa en la comparación de porcentajes entre los dos grupos estudiados (χ2 = 0.2; p = 0.6). Conclusiones: El porcentaje de mejoría clínica entre los dos tratamientos de esteroides tópicos fue semejante.


OBJECTIVE: To compare clinical improvement between treatment with metilprednisolone aceponate vs. betamethasone dipropionate among children with nonretractable prepuce. MATERIAL AND METHODS: Between August 2001 and November 2002, we carried out a double blind and controlled clinical trial in 34 children with a diagnosis of nonretracable prepuce. Children were randomly assigned to one of the following groups and topical treatment was administered: Group A; metilprednisolone aceponate 0. I 1% and Group B; betamethasone dipropionate 0.05%. RESULTS: Improvement was noted in 88.2% of our sample studied; (n= 15) children from group A and 76.4% (n= 13) childrenfrom group B; however, we did not observe a significant difference when comparing percentages between the two groups (chi2 = 0.2; p = 0.6). CONCLUSIONS: The percentage of clinical improvement was similar between the two groups of topical steroid treatment administered.
