Criptococosis pulmonar en un paciente con colitis ulcerativa tratado con prednisolona y azatioprina / Pulmonary cryptococcosis in a patient with ulcerative colitis treated with prednisolone and azathioprine

Resumen La enfermedad inflamatoria intestinal comprende la enfermedad de Crohn (EC) y la colitis ulcerativa (CU). Esta última es una patología crónica caracterizada por una inflamación difusa de la mucosa colónica, que afecta el recto y se extiende de forma proximal. Su curso clínico es intermitente, con exacerbaciones y remisiones. Su tratamiento, por lo general, es farmacológico, con corticoides, inmunomoduladores e inhibidor del factor de necrosis tumoral (anti tumor necrosis factor, TNF), los cuales causan un estado de inmunosupresión en el paciente, que puede asociarse en algunos casos a infecciones oportunistas. En la literatura se describe la aparición de la criptococosis pulmonar en pacientes con infección por el virus de inmunodeficiencia humana (VIH). En otros casos se asocia al tratamiento farmacológico de pacientes con EC, así como con otras infecciones oportunistas, tales como la tuberculosis y el herpes. Presentamos uno de los primeros casos de criptococosis pulmonar en un paciente con diagnóstico de colitis ulcerativa, quien recibió tratamiento escalonado con salicilatos, inmunomoduladores y terapia biológica. La infección fue documentada clínica, radiológica e histológicamente. El paciente recibió el tratamiento adecuado y presentó una evolución satisfactoria.

Abstract Inflammatory bowel disease comprises Crohn's disease (CD) and ulcerative colitis (UC), the latter being a chronic disease characterized by diffuse inflammation of the colonic mucosa that affects the rectum and extends proximally. Its clinical course is intermittent with exacerbations and remissions and its treatment is generally pharmacological, with steroids, immunomodulators, and anti-tumor necrosis factor inhibitors (TNF), which cause the patient to be in a state of immunosuppression associated, in some cases, with opportunistic infections. The literature describes the occurrence of pulmonary cryptococcosis in patients with human immunodeficiency virus (HIV) infection, in cases associated with drug treatment of patients with CD, as well as with other opportunistic infections such as tuberculosis and herpes. This is one of the first cases of pulmonary cryptococcosis reported in a patient diagnosed with ulcerative colitis, who received step therapy with salicylates, immunomodulators, and biological therapy. The infection was documented clinically, radiologically, and histologically. The patient received the appropriate treatment and had a satisfactory evolution.

A comparison of single-dose and multiple divided daily-dose oral steroids for sudden sensorineural hearing loss / Comparação entre dose única e múltiplas doses diárias de corticoides para perda auditiva neurossensorial súbita

Abstract Introduction: Glucocorticoids are considered the first-line therapy for sudden sensorineural hearing loss. But there is currently no consensus on administering them as a single dose versus multiple divided daily doses. Objective: We aim to evaluate the treatment outcome of sudden sensorineural hearing loss between a single-dose and multiple divided daily doses of steroid treatment. Methods: A total of 94 patients who were diagnosed and treated for sudden sensorineural hearing loss and followed up for more than three months were reviewed retrospectively. Patients were divided into single-dose and multiple divided-dose groups, based on their medication regimens. Hearing thresholds were repeatedly measured: on the initial visit and 1 week, 1 month, and 3 months after the initial treatment. Treatment outcomes were analyzed by comparing hearing recovery rates and post-treatment audiometric changes. Results: The hearing threshold was significantly reduced at three months post-treatment in both groups. The hearing recovery rate of the single-dose group was significantly higher than that of the multiple divided-dose groups. Audiometric changes showed no statistical difference either in pure tone threshold or speech discrimination. Conclusion: When oral steroids are indicated for sudden sensorineural hearing loss, both a single dose and multiple divided doses can be effective for treatment and have comparable results. However, the single-dose regimen seems to be more efficacious than the divided-dose regimen.

Resumo Introdução: Os glicocorticoides são considerados terapia de primeira linha para perda auditiva neurossensorial súbita. Contudo, atualmente não há consenso em como para administrá-los, se em dose única ou múltiplas doses diárias. Objetivo: Nosso objetivo é avaliar o resultado do tratamento da perda auditiva neurossensorial súbita com uma dose única ou várias doses diárias de tratamento com esteróides. Método: Um total de 94 pacientes que foram diagnosticados e tratados para perda auditiva neurossensorial súbita e acompanhados por mais de três meses pós-tratamento foram avalia-dos retrospectivamente. Os pacientes foram divididos em grupos de dose única diária e dose diária dividida em múltiplas tomadas, baseado em seu regime medicamentoso. Os limiares auditivos foram medidos repetidamente: na visita inicial e em 1 semana, 1 mês e 3 meses após o tratamento inicial. Os resultados do tratamento foram analisados comparando-se as taxas de recuperação da audição e as alterações audiométricas pós-tratamento. Resultados: O limiar auditivo foi significativamente reduzido aos três meses pós-tratamento em ambos os grupos. A taxa de recuperação auditiva no grupo de dose única foi significativamente maior do que no grupo de dose diária dividida em múltiplas tomadas. As alterações audiométricas não mostraram diferença estatística, tanto no limiar de tom puro quanto na discriminação da fala. Conclusão: Quando esteroides orais são indicados para perda auditiva neurossensorial súbita, tanto uma dose única quanto múltiplas doses podem ser eficazes para o tratamento e têm resultados comparáveis. No entanto, o regime de dose única diária parece ser mais eficaz do que o regime de dose diária dividida em múltiplas tomadas.

Chronic equine proliferative pododermatitis: case report / Pododermatite proliferativa crônica equina: relato de caso

Chronic equine proliferative pododermatitis (canker) is a chronic hypertrophic disease of the hoof, denoted by an excessive proliferation of the horn-producing tissues, which results from a dyskeratosis of the keratinocytes. It occurs mainly at the frog and sulci regions, but can sometimes also affect the heels, sole, bulbs or hoof wall. The etiology still remains unclear. Infectious agents such as anaerobic bacteria, viruses, spirochetes and fungi have been isolated from diseased tissues, but, moreover, an immune cause has been suggested, possibly related to a genetic predisposition. This report shows a case of a Brazilian Sport Horse, 10 years old, that had been affected on the right hindlimb for more than two years without a concise diagnosis. Success was achieved with the treatment consisting of oral prednisolone and topical Purple Mush(AU)

Pododermatite proliferativa crônica equina (cancro) é uma doença hipertrófica dos cascos, caracterizada por uma proliferação excessiva dos tecidos produtores de túbulos, o que resulta de uma disqueratose dos queratinócitos. Concentra-se principalmente na região da ranilha e seus sulcos, mas algumas vezes pode afetar também talões, bulbos, sola e parede do casco. A etiologia ainda não foi confirmada. Agentes infecciosos como bactérias anaeróbias, vírus, espiroquetas e fungos já foram isolados de tecidos afetados, mas cada vez mais uma hipótese imune vem sido discutida, possivelmente relacionada a uma predisposição genética. Este relato traz o caso de um Brasileiro de Hipismo, 10 anos, afetado no membro pélvico direito há mais de dois anos sem um diagnóstico conciso. O êxito foi obtido com o tratamento consistindo em Prednisolona oral e Purple Mush tópico.(AU)

Comparative study on the efficacy of non-steroidal, steroid and non-use of anti-inflammatory in the treatment of acute epidemic conjunctivitis

Abstract Purpose To evaluate the effects of prednisolone against sodium diclofenac both with ciprofloxacin compared to artificial tears on the symptoms and signs of acute viral conjunctivitis. Methods Study included 37 patients diagnosed with acute conjunctivitis and distributed by three groups: A (1% prednisolone acetate + ciprofloxacin (0.3%); B (Sodium diclofenac (0.1%) + ciprofloxacin (0.3%) and C (artificial tears + ciprofloxacin (0.3%). Patients received medication 6/6 hours daily. Signs and symptoms (e.g. lacrimation, burning, photophobia, etc.) were scored at baseline and on the first, third, fifth and seventh days and in the end of treatment using a standardized questionnaire and slit lamp anterior segment examination. Results All three groups demonstrated an improvement in the signs and symptoms of conjunctivitis in their follow-up visits. There was no significant difference in symptom and sign scores between Group A and B and B and C in the study visits ( p >0.05). However, the comparison between groups A and C showed a clinical trend (p=0.05) on third evaluation suggesting better clinical action using the corticosteroids. Conclusion The prednisolone acetate was not superior to the use of sodium diclofenac or artificial tears in relieving the signs and symptoms of viral conjunctivitis.

Daño de órgano en una cohorte de pacientes colombianos con lupus eritematoso sistémico: caracterización y factores asociados / Organ damage in a cohort of Colombian patients with systemic lupus erythematosus: Characterization and associated factors

RESUMEN El daño irreversible de órgano es predictor de morbilidad, mortalidad, mayor acúmulo de daño y mala calidad de vida en los pacientes con lupus eritematoso sistémico. Objetivos: Caracterizar el daño y los factores que mejor lo explican, en una población de pacientes colombianos con lupus eritematoso sistémico. Métodos: Estudio retrospectivo de seguimiento a una cohorte. El daño se midió con el SLICC/ACR (índice de Systemic Lupus International Collaborating Clinics y del American College of Rheumatology) y la actividad de la enfermedad por SELENA SLEDAI. La caracterización del daño se hizo mediante estadística descriptiva, los factores asociados con el desenlace se evaluaron con Chi2 de Pearson o Fisher, t de Student o U de Mann-Whitney; la proporción de pacientes que acumularon daño se evaluó con el test de Friedman y el puntaje acumulado con el test de Wilcoxon. La determinación de los factores asociados independientemente con el desenlace se hizo con una regresión logística. Resultados: Se incluyeron 161 pacientes con diagnóstico de novo y seguimiento mínimo de un año; el 28,9% sufrió daño. Los dominios más representados fueron el neuropsiquiátrico, renal y vascular. Los anticuerpos antifosfolípido, las dosis promedio de prednisolona mayores a 12,5 mg/día y presentar 2 o más recaídas se asociaron independientemente al daño orgánico. Conclusiones: Los anticuerpos antifosfolípido, la dosis de esteroides y la frecuencia de recaídas se asocian al daño orgánico en una población colombiana de pacientes con lupus eritematoso sistémico.

ABSTRACT Irreversible organ damage is a predictive factor of morbidity, mortality, increased accumulation of damage, and poor quality of life in patients with systemic lupus erythematosus. Objectives: To describe the damage, and the factors that best explain it, in a population of Colombian patients. Methods: A retrospective follow-up study of a patient cohort. The damage was measured using the Systemic Lupus International Collaborating Clinics (SLICC) and the American College of Rheumatology (ACR) index, and disease activity by SELENA SLEDAI. Descriptive statistics were used to describe the damage. The factors associated with the outcome were evaluated with Pearson's or Fisher's Chi2, Student's t or Mann-Whitney's U. The proportion of patients that accumulated damage was evaluated with the Friedman test, and the cumulative score with the Wilcoxon test. The determination of the factors independently associated with the outcome was performed using logistic regression. Results: A total of 161 patients with recent diagnosis, and followed for one year or more, were included, 28.9% of whom had suffered damage. The most represented domains were neuropsychiatric, renal and vascular. Anti-phospholipid antibodies, mean doses of prednisolone greater than 12.5 mg/day, and suffering 2 or more relapses were independently associated with organ damage. Conclusions: Anti-phospholipid antibodies, steroid doses and frequency of relapses are associated with organ damage in a Colombian population of patients with systemic lupus erythematosus.

A case of retroperitoneal fibrosis responding to steroid therapy

ABSTRACT A 69-year-old man presented at the hospital with complaints of prolonged stomach pain extending from the week prior. Enhanced computed tomography (CT) revealed a low density area in the retroperitoneal space. A radiologist diagnosed the patient with retroperitoneal fibrosis. One week later, an enhanced CT revealed an exponential increase of the low density area and slight right hydronephrosis. Upon admission, prednisolone administration was initiated at a dose of 40mg/day. The size of the retroperitoneal soft tissue mass decreased gradually. Although the dose of prednisolone was tapered to 5mg, the patient is doing well without any sign of recurrence.

Pénfigo vulgar oral: reporte de un caso clínico / Oral penphigus vulgaris: report of a clinical case

El pénfigo vulgar es el tipo más común de un grupo padecimientos crónicos autoinmunes identificados por la presencia de lesiones ampulosas situadas en las mucosas y piel. El pénfigo vulgar oral (PVO) se caracteriza por la presencia de ampollas localizadas en las encías, paladar blando, carrillos, pero cualquier sitio de la cavidad oral puede ser afectado. Estas lesiones se presentan primero en la cavidad oral y meses después en la piel, por lo que su diagnóstico temprano y oportuno es vital para el pronóstico. El propósito de este trabajo es presentar esta condición clínica en una persona adulta mayor.

Pemphigus vulgaris is the most common of a group of chronic autoim-mune conditions characterized by the presence of mucosal and dermal blisters. In the case of oral pemphigus vulgaris (OPV), these are typi-cally found on the gums, soft palate, and cheeks, though anywhere in the oral cavity can be affected. These lesions appear first in the oral cavity and then, months later, on the skin. Therefore, early diagnosis is crucial for prognosis. The aim of this paper is to present a case report of this condition in an older adul.

Fibrosis retroperitoneal idiopática / Idiopathic retroperitoneal fibrosis

Mujer de 36 años de edad quien consulta por cuadro clínico de ocho meses de evolución consistente en dolor abdominal, asociado a diarrea y emesis, siendo manejada inicialmente como cuadro de colon irritable. Ante la persistencia del dolor solicitan estudios imagenológicos con hallazgos sugestivos de masa retroperitoneal por lo cual remiten para valoración por cirugía. Al examen físico se encuentra dolor a la palpación abdominal generalizada sin adenopatías o masas. Paraclínicos con resonancia abdominal evidenciando masa sólida retroperitoneal de localización paraaórtica izquierda y espacio interaortocavo, englobando de forma circunferencial la aorta abdominal a la emergencia de arterias renales comprometiendo tejidos adyacentes, con disminución del tamaño del riñón izquierdo, compensando con hipertrofia del riñón derecho. Marcadores tumorales negativos, colonoscopia sin evidencia de masas. Es llevada a biopsia guiada por TAC con patología conclusiva de fibrosis retroperitoneal idiopática. Conclusión: se presenta un caso de fibrosis retrooperitoneal idiopática, enfermedad de muy bajafrecuencia de presentación en la práctica clínica diaria. (Acta Med Colomb 2015: 40: 260-262).

The case of a 36-year-old woman who consults for history of abdominal pain associated to diarrhea and emesis of eight months of evolution, being initially handled as irritable bowel syndrome, is presented. Given the persistence of pain, imaging studies suggestive of retroperitoneal mass were requested and were referred for assessment by surgery. Physical examination showed generalized pain at abdominal palpation without lymphadenopathy or masses. Abdominal resonance showed solid retroperitoneal mass of left para-aortic location and interaortocaval space, circumferentially encompassing the abdominal aorta at the emergence of renal arteries engaging adjacent tissue with decreased size of the left kidney, compensated by right kidney hyperthrophy. Tumor markers were negative, and colonoscopy did not show evidence of masses. A carried CT-guided biopsy was performed with conclusive pathology of idiopathic retroperitoneal fibrosis. Conclusion: a case of idiopathic retroperitoneal fibrosis, disease with very low frequency in everyday clinical practice, is presented. (Acta Med Colomb 2015: 40: 260-262).

Whole-genome sequences of influenza A(H3N2) viruses isolated from Brazilian patients with mild illness during the 2014 season

The influenza A(H3N2) virus has circulated worldwide for almost five decades and is the dominant subtype in most seasonal influenza epidemics, as occurred in the 2014 season in South America. In this study we evaluate five whole genome sequences of influenza A(H3N2) viruses detected in patients with mild illness collected from January-March 2014. To sequence the genomes, a new generation sequencing (NGS) protocol was performed using the Ion Torrent PGM platform. In addition to analysing the common genes, haemagglutinin, neuraminidase and matrix, our work also comprised internal genes. This was the first report of a whole genome analysis with Brazilian influenza A(H3N2) samples. Considerable amino acid variability was encountered in all gene segments, demonstrating the importance of studying the internal genes. NGS of whole genomes in this study will facilitate deeper virus characterisation, contributing to the improvement of influenza strain surveillance in Brazil.

Efficacy and tolerability of a gatifloxacin/prednisolone acetate fixed combination for topical prophylaxis and control of inflammation in phacoemulsification: a 20-day-double-blind comparison to its individual components

OBJECTIVE: To compare the efficacy and tolerability of a fixed combination of 0.3% gatifloxacin and 1% prednisolone (Zypred®) versus the individual components used separately (Zypred® and Predfort®) for infection prophylaxis and inflammation control after cataract surgery with intraocular lens implantation. METHODS: A prospective, randomized, double-blind, parallel-group study of 108 patients who underwent phacoemulsification and intraocular lens implantation was conducted. After random assignment, 47 eyes received the fixed combination of topical 0.3% gatifloxacin/1% prednisolone drops, and 61 eyes received the same doses of the individual components as separate solutions four times a day for 15 days. Baseline and postoperative assessments were made on postoperative days 1, 7, 15, and 20. RESULTS: All objective (best corrected visual acuity, sign of active ocular inflammation, central and incisional corneal edema, the number of cells per high-power field in the anterior chamber, and intraocular pressure) and subjective (eye pain, photophobia, burning sensation, itching, and foreign body sensation) criteria of efficacy were similar in both groups, with no significant differences. Group I included 47 eyes that received the fixed combination of gatifloxacin/prednisolone acetate eye drops and a placebo eye drop solution. Group II included 61 eyes that were treated with 0.3% gatifloxacin and 1% prednisolone acetate eye drops separately. The intraocular pressure was slightly higher in Group II (p<0.05). CONCLUSION: Treatment with the fixed-dose combination of gatifloxacin/prednisolone eye drops was as effective as the non-fixed combination in preventing infection and controlling inflammation after phacoemulsification and intraocular lens implantation. .

Metilprednisolona intratimpânica como terapia de resgate na surdez neurossensorial súbita / Intratympanic methylprednisolone as rescue therapy in sudden sensorineural hearing loss

O tratamento da surdez súbita é uma das questões mais controversas da Otologia. No entanto, os corticoides sistêmicos têm sido a opção mais escolhida por referidos autores como padrão ouro de tratamento. O uso de corticoide intratimpânico como terapia de segunda linha para tratamento de casos refratários de surdez súbita tem sido relatado e os resultados promissores têm feito alguns autores promoverem o seu uso como terapia de primeira linha, indicando-a para todos os casos de surdez súbita. OBJETIVOS: Descrever essa nova modalidade de tratamento e avaliar a sua segurança e eficácia em quatorze pacientes tratados após falha da corticoterapia oral. MATERIAIS E MÉTODOS: Trata-se de estudo analítico prospectivo em que quatorze pacientes portadores de surdez súbita neurossensorial foram tratados com metilprednisolona intratimpânica após falha da corticoterapia oral. Limiares tonais e o índice de reconhecimento de fala pré-tratamento e pós-tratamento foram analisados. RESULTADOS: Dez dos quatorze pacientes tratados com metilprednisolona intratimpânica apresentaram recuperação da audição superior a 20 dB nos limiares tonais ou 20 por cento no IRF. CONCLUSÃO: Três injeções intratimpânicas de metilprednisolona aumentaram os limiares tonais e índices de reconhecimento da fala em um grupo de pacientes portadores de surdez súbita neurossensorial que não obtiveram benefício após corticoterapia oral.

Treatment in sudden sensorineural hearing loss is a contentious issue, today, oral steroids are the most common choice and considered the best treatment option, but the use of intratympanic steroids has become an attractive alternative, especially in cases when systemic therapy fails, or to avoid the side effects of the systemic use of steroids. AIM: To describe the results of intratympanic methylprednisolone in idiopathic sudden sensorineural hearing loss after failure of oral prednisolone. METHODS: In a prospective study fourteen patients with idiopathic sudden sensorineural hearing loss were treated with intratympanic methylprednisolone after failing in the treatment with systemic steroids. Pretreatment and post-treatment audiometric evaluations including pure tone average (PTA) and speech reception thresholds (SRT) were analyzed. RESULTS: Ten from 14 patients treated with intra-tympanic methylprednisolone presented with hearing recovery > 20 dB in PTA or 20 percent in SRT. CONCLUSION: Three intratympanic injections of methylprednisolone improved pure-tone average or speech discrimination scores for a subset of sudden hearing loss subjects that failed to benefit from oral steroids.

Manifestaciones bucales en pacientes con Lupus Eritematoso Sistémico / Oral manifestations in patients with Systemic Lupus Erythematosus

Introducción. El Lupus Eritematoso Sistémico (LES), es una enfermedad autoinmune inflamatoria crónica multisistémica. Los pacientes frecuentemente presentan manifestaciones bucales, lo cual puede ser el primer indicio de la enfermedad. Las lesiones bucales han sido clasificadas como: eritematosas, discoides y de tipo ulcerativo. Este estudio tuvo como objetivo describir las manifestaciones de los tejidos blandos bucales en pacientes con diagnóstico de LES y establecer si existe relación entre estas manifestaciones con el tiempo de diagnóstico de la enfermedad, los marcadores inmunológicos, el compromiso sistémico el tratamiento farmacológico.Materiales y métodos. Se incluyeron 66 pacientes con diagnóstico de LES; se les realizó un examen estomatológico y se recolectó información demográfica, clínica y de tratamiento por medio de revisión de historias clínicas y una entrevista. A diez pacientes se les realizó análisis citológico para candidiasis.Resultados. 55 pacientes presentaron algún tipo de lesión en cavidad bucal, las cuales fueron: lesiones “sugestivas de candidiasis”, en 26 pacientes; petequias, en 23; úlceras, en 17 y queilitis actínica, en 11 pacientes. La candidiasis oral se asoció con el uso de prednisolona; de los 57 pacientes que tomaban este medicamento, 45.6 presentaban lesiones “sugestivas de candidiasis”. Sin embargo, no hay asociación entre la dosis exacta de prednisolona y la presencia o ausencia de lesiones.Conclusiones. Los pacientes a quienes se les administra prednisolona, tienen un riesgo de presentar lesiones “sugestivas de candidiasis” 15.98 veces más que los que no la toman. Sin embargo, no se encontró asociación con ningún compromiso sistémico y la presencia de lesiones orales.

Objective. Patients with Systemic Lupus Erythematosus (SLE) frequently experience oral manifestations, which can be the first symptom of the disease. Our objective was to describe the manifestations of oral soft tissue in patients diagnosed with SLE, and to establish whether or not there is a relationship between these manifestations and the time at which the disease was diagnosed, the immunological markers, systemic compromise, and pharmacological treatment.Methods. 66 patients diagnosed with SLE were included in the study. Each patient underwent an estomatological examination, and their demographical, clinical, and treatment information was gathered by way of reviewing their clinical history and by participating in an interview. Cytological analysis was performed on ten patients to test for candidiasis.Results. 55 patients presented some type of oral cavity lesion, which included: 26 patients with lesions “suggestive of candidiasis”, 23 with petechiae, 17 with ulcers, and 11 with actinic cheilitis. Oral candidiasis was associated with the use of prednisolone. Of the 57 patients who took this medicine, 45.6 hadlesions “suggestive of candidiasis”. However, there is no association between the presence or absence of lesions and the exact dose of prednisolone taken.Conclusions. Patients taking prednisolone have 15.98 times more probability of suffering lesions “suggestive of candidiasis” than those who do not take this medication. However, no association was found between systemic compromise and the presence of oral lesions.

Uso bem-sucedido do corticóide na hepatite alcoólica grave / Sucessful use of steroids in severe alcoholic hepatitis

Abuso e dependência alcoólica são os mais sérios problemas médicos do mundo industrializado. Cerca de 10% a 35% dos alcoólatras cursam com hepatite crônica ativa, síndrome inflamatória que traduz necrose hepática em diferentes graus de intensidade, dependentes da quantidade de álcool ingerido diariamente ao longo dos anos. Alguns revelam-se pouco sintomáticos ou assintomáticos. Forma mais grave da doença expressa-se pelo aparecimento de icterícia, ascite, sinais de coagulopatia e até encefalopatia. Esses doentes cursam ainda com dor em hipocôndrio direito, hepatomegalia, febre e leucocitose. A mortalidade nesse caso é alta, todos evoluindo com neutrofilia, metabolismo alterado dos carboidratos, lipídeos e minerais. Nesses casos graves, a literatura mundial preconiza, dentre outras terapias, o uso de corticóides com o objetivode suprimir a inflamação tecidual, diminuir a formação de colágeno, bloquear os mecanismos de perpetuação imunológica da doença, melhorar o apetite e estimular a síntese de albumina. Este artigo tem por objetivo apresentar um caso de hepatite alcoólica aguda grave que evoluiu com sucesso após o tratamento com corticóide e revisar esse tema tão atual e problemático em nosso país.

Linfoma de Hodkin en Chile: Experiencia de 15 años del Programa Nacional de Cáncer del Adulto / Hodgkin lymphoma in Chile: Experience of the national adult cancer program

Background: Hodgkin lymphoma is a highly curable disease. Aim: To evaluate the clinical characteristics and the treatment results of Hodgkin lymphoma patients of the National Cancer Program in Chile. Patients and methods: Prospective assessment of 682 patients treated in 18 adult cancer centers. Progression free survival (PFS) and overall survival (OS) were calculated. Median follow up was 127, 95, 87, 72 and 50 months for C-MOPP, radiotherapy (RT), C-MOPP/ABV, NOVP and ABVD, respectively. Results: Median age was 37 years (15-84). Nodular sclerosis and mixed cellularity were equally expressed. Advanced stages (III & IV) were present at diagnosis in 61 percent of cases. Age over 40 was an adverse prognostic factor (p <0.001). The rate of PFS at 5 and 10 years for early stages was 73 percent and 66 percent with RT, 80 percent and 74 percent with C-MOPP+RT, 73 percent and 71 percent with C-MOPP/ABV, 59 percent and 59 percent with NOVP+RT, and 81 percent with ABVD+RT, at 5 years, being significantly lower for NOVP (p =0.02). The rate of OS at 5 and 10 years for advanced stages was 82 percent and 70 percent with RT, 82 percent and 76 percent with C-MOPP+RT, 82 percent and 80 percent with C-MOPP/ABV, 68 percent and 60 percent with NOVP, and 85 percent with ABVD at 5 years, also significantly lower for NOVP (p =0.04). For advanced stages, the rate of PFS at 5 and 10 years was 49 percent and 43 percent with C-MOPP, 69 percent and 62 percent with C-MOPP/ABVD or C-MOPP/ABV, and 71 percent at 5 years with ABVD, significantly lower for C-MOPP (p =0.01). The rate of OS at 5 and 10 years was 52 percent and 46 percent with C-MOPP, 70 percent and 63 percent with C-MOPP/ABVD or C-MOPP/ABV and 76 percent with ABVD at 5 years, significantly lower for C-MOPP (p =0.0002). Conclusions: Age over 40 years was an adverse prognostic factor. C-MOPP/ABVD, C-MOPP/ABV and ABVD had comparable results and reached a high tumor control and overall survival in both early...

Paquimeningitis hipertrófica, glomerulonefritis y vasculitis de pequeños vasos asociada a ANCA / Hypertrophic pachymeningitis, glomerulonephritis and P-ANCA associated small vessel vasculitis

La paquimeningitis hipertrófica es una enfermedad poco frecuente caracterizada por engrosamiento de la duramadre. Presentamos una paciente con esta enfermedad que se manifestó con cefalea crónica y en la que concomitantemente se evidenció una glomerulonefritis necrotizante extracapilar pauciinmune asociada a anticuerpos anticitoplasma de neutrófilos de patrón perinuclear (ANCA-P). El diagnóstico se estableció por resonancia nuclear magnética. Recibió tratamiento inmunosupresor con prednisona y ciclofosfamida con evolución favorable.

Hypertrophic pachymeningitis is a very unusual disease, the main characteristic of which is thickening of the dura mater. We describe a patient who started this illness showing chronic headache and pauci-immune necrotizing extracapillary perinuclear antineutrophil cytoplasmic antibody (P-ANCA) associated glomerulonephritis. The diagnosis was made by brain magnetic resonance image. She received immunosuppressant therapy with prednisonel and cyclophosphamide with clinical improvement.

Manejo conservador de la enfermedad periodontal crónica en presencia de lesiones vesiculobulosas: reporte de dos casos de pénfigo vulgar / Conservative management of chronic periodontal disease in the presence of vesiculobullous lesions: report of two cases of pemphigus vulgaris

Se reportan dos casos clínicos de pénfigo vulgar, confirmados a través del examen histopatológico, con localización en la región mucogingival de cavidad bucal, en pacientes con presencia de enfermedad periodontal crónica moderada avanzada. El tratamiento periodontal a emplearse en pacientes con lesiones bucales vesiculobullosas como el pénfigo vulgar, puede ser considerado conservador, evitando así la consecuente descamación epitelial de la superficie mucosa y la posterior ulceración de la misma al realizarse tratamientos orientados a las periodontopatías

Bone marrow transplantation in thalassaemia patients in Shiraz, Islamic Republic of Iran

We report the results of allogeneic bone marrow transplantation in 26 female and 37 male patients with beta-thalassaemia major [age range: 2-17 years], performed at Namazi Hospital over the period 1992-99. In all cases, standard conditioning and immunosuppressive regimens were employed. Currently, 50 patients remain thalassaemia-free, 9 of whom have developed chronic graft-versus-host disease. There were 8 deaths among the 13 unsuccessful transplant cases: 4 due to acute uncontrollable graft-versus-host disease, and 4 to non-transplant-related causes such as hypoglycaemia, hypersensitivity reactions and advanced disease. We conclude that allogeneic bone marrow transplantation is an effective therapy for the treatment of beta-thalassaemia major, particularly for patients classified as classes I and II
