ABSTRACT

La hemosiderosis pulmonar idiopática (HPI) es una patología poco frecuente; su distribución geográfica, su incidencia y prevalencia se desconocen de manera exacta a nivel mundial. Tiene una fuerte asociación con condiciones autoinmunes y una adecuada respuesta al tratamiento inmunosupresor. A pesar de ser una patología grave, presenta una tasa de morbilidad y mortalidad mediana, siempre que se realice un diagnóstico y tratamiento precoz. Se presenta el caso clínico de una paciente femenina con diagnóstico de HPI quien cursó con la triada clásica de esta enfermedad: hemoptisis, anemia ferropénica e infiltrados pulmonares difusos. Se descartaron otras causas de hemorragia pulmonar difusa y se realizó el diagnóstico por biopsia pulmonar. Se trató con esteroides sistémicos e inhalados y azatioprina. Tras casi 2 años después del diagnóstico, estando sin tratamiento por 3 meses, presentó una exacerbación con hemorragia pulmonar masiva ocasionando el fallecimiento de la paciente.


Idiopathic pulmonary hemosiderosis (IPH) is a rare pathology; its geographic distribution, incidence and prevalence are not accurately known worldwide. It has a strong association with autoimmune conditions and has an adequate response to immunosuppressive treatment. Despite being a serious pathology, it has a medium morbidity and mortality rate, provided that early diagnosis and treatment is performed. We present the clinical case of a female patient diagnosed with IPH who presented with the classic triad of this disease: hemoptysis, iron deficiency anemia and diffuse pulmonary infiltrates. Other causes of diffuse pulmonary hemorrhage were ruled out and the diagnosis was made by lung biopsy. She was managed with systemic and inhaled steroids and azathioprine. After almost 2 years before the diagnosis, being without treatment for 3 month she had a massive pulmonary hemorrhage, causing the death of the patient.

ABSTRACT

Hemochromatosis (HC) is a disorder that alters the body's ability to metabolize iron, increasing its absorption, causing iron overload, and consequently an accumulation of the mineral in multiple organs such as the liver, heart, and pancreas. The amount of total iron in the body is 2-4 g in healthy individuals and remains within these limits throughout life thanks to the control of intestinal absorption. In patients with CH, this amount is increased by at least 10 times, which translates into body deposits of 20-40 grams of iron on average. Factors that increase the risk of having HC: having two copies of the mutated HFE gene, family history, ethnicity or ancestry from Northern Europe (less common in blacks, Hispanics, and Asians), and male gender.

ABSTRACT

La hemosiderosis pulmonar idiopática (HPI) es una causa de hemorragia alveolar difusa. OBJETIVO: describir la evolución de niños con HPI en nuestra institución. Se realizó una revisión retrospectiva con protocolo de seguimiento. Se reclutaron 13 pacientes, 7 hombres. Procedentes de una zona agrícola (6/13). No todos presentaron la tríada diagnóstica completa: infiltrados algodonosos (9/13), anemia (11/13), hemoptisis (9/13). Todos evidenciaron un recuento de hemosiderófagos sobre 30% en el lavado broncoalveolar. Tomografía computada de tórax: normal (5/13), patrón intersticial (5/13), vidrio esmerilado (2/13) y fibrosis (1/13). Espirometría: normal (7/13), restrictiva (4/13), obstructiva (1/13) y no efectuada (1/13). Tratamiento durante la fase aguda: bolos de metilprednisolona (7/13) o prednisona (6/13) o hidrocortisona (1/13). En la fase de mantención se administró: prednisona (13/13) más un inmunosupresor, azathioprina (12/13), hidroxicloroquina (1/13), micofenolato (1/13), más budesonida MDI (13/13). Ocho pacientes detuvieron los sangrados. Dos pacientes fallecieron y hubo cinco embarazos de curso fisiológico en 3 adolescentes. Se observó: a) diferentes modalidades de presentación que retrasaron el diagnóstico; b) gran exposición a pesticidas; c) mejor pronóstico si el diagnóstico y el tratamiento eran precoces, también en niñas adolescentes; d) la mayoría detuvo los episodios de sangrado.


Idiopathic pulmonary hemosiderosis (IPH) is a cause of diffuse alveolar hemorrhage. OBJECTIVE: to describe the evolution of children with IPH in our institution. Retrospective monitoring with a follow-up protocol was carried out. 13 patients, seven males, were recruited. From an agricultural area (6/13). Not all of patients had the complete diagnostic triad: cotton infiltrates (9/13), anemia (11/13), hemoptysis (9/13). Hemosiderin-laden macrophages counting in the bronchoalveolar lavage fluid was over 30% in all the patients. Computed chest tomography was informed as normal (5/13), interstitial pattern (5/13), ground glass (2/13) and fibrosis (1/13). Spirometry: normal (7/13), restrictive (4/13), obstructive (1/13) and not performed (1/13). Treatment during the acute phase: bolus of methylprednisolone (7/13) or prednisone (6/13) or hydrocortisone (1/13). In the maintenance phase: prednisone (13/13) plus an immunosuppressant, azathioprine (12/13), hydroxychloroquine (1/13), mycophenolate (1/13), plus budesonide MDI (13/13). Eight patients stopped the bleeding episodes. Two patients died and there were five physiological pregnancies in 3 adolescents. It was observed:(a) different modes of IPH presentation that delayed its diagnosis; (b) large exposure to pesticides; (c) prognosis improved if diagnosis and treatment were early, also in adolescent girls; (d) most of the patients stopped the bleeding episodes.

ABSTRACT

Introduction. L'hémosidérose du système nerveux central est une pathologie rare liée au dépôt d'hémosidérine à la surface du cerveau, des nerfs crâniens et de la moelle épinière secondaire à un saignement chronique. Nous rapportons un cas d'hémosidérose du système nerveux central chez une patiente jeune dans un tableau de méningite. A travers notre observation nous voulons décrire l'apport diagnostique de l'Imagerie par Resonnace Magnétique dans cette pathologie. Observation. Patiente de 39ans, sans antécédents particuliers, avait consulté au service des urgences pour des céphalées d'apparition brutale associées à des nausées. Le scanner cérébral objectivait un discret effacement des sillons corticaux et une sinusite sphénoïdale. L'Imagerie par Resonnace Magnétique cérébrale et médullaire objectivait un dépôt d'hémosidérine en hyposignal T2 Echo de gradient au niveau du cortex cérébral et de la moelle épinière. Le bilan étiologie du saignement chronique était négatif à l'angio-Imagerie par Resonnace Magnétique du polygone de Willis. La glycorachie était à 1,5g/l pour une glycémie à 5,6g/l (hypoglycorachie), la protéinorachie était à 2,43g/l sans bactériémie mais présence de 590 éléments dont 72% de lymphocytes et 27% de polynucléaires neutrophiles. Conclusion. L'Imagerie par Resonnace Magnétique est une technique indispensable au diagnostic de l'hémosidérose cérébro-méningée.

ABSTRACT

We present the case-report of a one-month-old infant, admitted to the Emergency Department with hypovolemic shock secondary to pulmonary hemorrhage who required life-support measures, including vasoactive drugs and methylprednisolone pulses. She was discharged from the hospital after 13 days of evolution and then readmitted 5 days later for a new episode of hemoptysis with hemodynamic compromise. Fiberoptic bronchoscopy was performed 4 days after the first episode showed a normal anatomy, without active bleeding, with 20% of hemosiderophages in bronchoalveolar lavage. Diffuse infiltrates were found on the chest radiograph. Differents studies were performed for check-out infection, heart disease, immune disease, thrombophilia, celiac disease, swallowing disorder, vascular abnormalities and allergy to cow's milk protein were negative, which led to Idiopathic Pulmonary Hemosiderosis (IPH). It was managed with amino acid formula, daily oral prednisone until 6 months of age and then every other day, and permanent inhaled fluticasone. In subsequent controls, normal growth and development were found, with no recurrences up to the time of this report, at 1 year of age. The favorable evolution in this case is attributed to early diagnosis and timely treatment with systemic corticosteroids. A review of the topic of IPH in pediatrics is presented, and study and treatment algorithms are proposed.


Se presenta el caso de una lactante de un mes de edad, que se presentó en el Servicio de Urgencia con shock hipovolémico secundario a hemorragia pulmonar. Necesitó medidas de soporte vital, incluyendo drogas vasoactivas y pulsos de metilprednisolona. Egresó del hospital a los 13 días de evolución y reingresó 5 días después por nuevo episodio de hemoptisis con compromiso hemodinámico. La fibrobroncoscopía efectuada a los 4 días de evolución del primer episodio mostró una anatomía normal, sin sangrado activo, con 20% de hemosiderófagos en el lavado broncoalveolar. En la radiografía de tórax se encontró infiltrados difusos. Los estudios en busca de infección, cardiopatía, enfermedad inmunológica, trombofilia, enfermedad celíaca, trastorno de deglución, anomalías vasculares y alergia a la proteína de la leche de vaca resultaron negativos, por lo que se planteó una Hemosiderosis Pulmonar Idiopática (HPI). Se manejó con fórmula aminoacídica, prednisona oral diaria hasta los 6 meses de edad y después en días alternos y fluticasona inhalada permanente. En controles posteriores se constató crecimiento y desarrollo normal, sin recidivas hasta el momento de este reporte, con 1 año de edad. La evolución favorable en este caso se atribuye al diagnóstico precoz y tratamiento oportuno con corticoides sistémicos. Se presenta una revisión del tema de HPI en pediatría y se proponen algoritmos de estudio y tratamiento.

ABSTRACT

Resumen La hemosiderosis pulmonar idiopática es una entidad rara caracterizada por hemorragia alveolar capilar. Su tríada clásica es hemoptisis crónica o recurrente, anemia por deficiencia de hierro y opacidades en las imágenes pulmonares. El objetivo de esta revisión fue determinar la frecuencia en radiografía y tomografía de tórax, de los hallazgos de hemosiderosis pulmonar idiopática en adultos, reportados en la literatura durante los últimos 20 años, de acuerdo con los hallazgos semiológicos en imagen, localización y distribución. Se hizo una búsqueda de publicaciones en bases de datos. Se seleccionaron 42 estudios, se estratificaron variables y se recopilaron los hallazgos. La consolidación y las opacidades reticulonodulares fueron el hallazgo más frecuente en radiografía. En tomografía el hallazgo principal fue el vidrio deslustrado en la región basal. No hubo diferencias en los hallazgos semiológicos de imagen en cuanto al compromiso de acuerdo con el género, aunque las mujeres tendieron a presentar una distribución difusa.

Abstract Idiopathic pulmonary hemosiderosis is a rare entity characterized by capillary alveolar hemorrhage. Its classic triad is chronic or recurrent hemoptysis, iron deficiency anemia, and opacities in lung images. The objective of this review was to determine the frequency in chest radiography and chest tomography of the findings of idiopathic pulmonary hemosiderosis in adults, reported in the literature during the last 20 years, according to the semiological imaging findings, location and distribution. A search of publications in databases was made. Forty-two studies were collected, variables were stratified in different categories and the findings were compiled. The most frequent finding in chest radiography were consolidation and reticulonodular opacities. On the other hand, the main finding in tomography was ground glass opacities in the basal region. There were no differences in the pattern of compromise by gender, although women tended to have a more diffuse distribution. MÉD.UIS.2020;33(2):55-64.

ABSTRACT

@#Repeated blood transfusions in transfusion dependent thalassemia (TDT) leads to iron overload-related endocrine complications. Hypoparathyroidism (HPT) with severe signs of hypocalcemia is a recognized complication among these patients. A 14-year-old thalassaemic boy, on regular transfusion and on anticonvulsant therapy with a presumptive diagnosis of epilepsy for the last 1 year, was admitted with high fever and severe muscle cramps with positive Trousseau’s sign. He was diagnosed as a case of primary HPT and magnesium deficiency on the basis of low serum calcium, high phosphate, normal alkaline phosphates, very low intact parathyroid hormone (iPTH), normal serum vitamin D and very low serum magnesium level. His calcium, magnesium and phosphate level normalised following treatment with intravenous magnesium and calcium. His iPTH improved but remained at low normal. He was discharged from hospital with oral calcium, calcitriol, and magnesium supplementation. The anticonvulsant (Phenobarbitone) was successfully withdrawn gradually over the next six months without any recurrence of seizure in the subsequent 3 years of follow up. Acquired HPT (apparently from hemosiderosis) is a common cause of hypocalcemia; and magnesium depletion further complicated the situation leading to severe hypocalcemia with recurrent episodes of convulsion. Magnesium replacement improved the parathyroid hormone (PTH) value proving its role in acquired HPT. Very high phosphate level on admission and poor PTH response with respect to the low serum calcium, indicates intrinsic parathyroid pathology. Metabolic abnormalities should always be evaluated in thalassaemic subject with seizure disorder and it appears that the initial convulsive episodes were due to hypocalcemia. Muscle pain, cramps or convulsion may occur from HPT and simultaneous magnesium deficiency in transfusion dependent thalassaemic subjects. Metabolic correction is more important than anticonvulsant medication. Calcium and magnesium should both be assessed routinely in transfusion dependent thalassemic patients.

ABSTRACT

Abstract Introduction: Anemic patients with chronic kidney disease (CKD) can be divided into anemic patients without or with functional iron deficiency (FID). The increase in the number of cases of hemosiderosis in patients on hemodialysis (HD) attributed to excessive intravenous iron replacement has called for the investigation of the factors involved in the genesis of FID. Objectives: This study aimed to describe the prevalence of FID in patients with CKD on HD, characterize the included individuals in terms of clinical and workup parameters, and assess their nutritional, oxidative stress, and inflammation statuses. This cross-sectional study assembled a convenience sample of 183 patients with CKD on HD treated in Southern Brazil. Patients meeting the inclusion and exclusion criteria were divided into two groups, one with anemic subjects with FID and one with anemic patients without FID. Participants answered a questionnaire probing into socio-epidemiological factors, underwent anthropometric measurements, and were tested for markers of anemia, oxidative stress, inflammation, and nutrition. Statistical analysis: The date sets were treated on software package GraphPad InStat version 3.1. Variables were tested with the Kolmogorov-Smirnov, chi-square, Student's t, and Mann-Whitney tests. Statistical significance was attributed to differences with a p < 0.05. Results: Markers of inflammation were not statistically different between the two groups. Markers of anemia and nutrition were significantly lower in patients with FID. Patients with FID were prescribed higher doses of parenteral iron (p < 0,05). Discussion: FID was associated with lower nutritional marker levels, but not to increased levels of markers of inflammation or oxidative stress, as reported in the literature. Additional studies on the subject are needed.


Resumo Introdução: A anemia na DRC pode ser dividida em anemia sem deficiência funcional de ferro e com deficiência funcional de ferro (ADFF). Diante do aumento dos casos de hemossiderose em pacientes em hemodiálise, atribuídos à reposição excessiva de ferro endovenoso, maiores conhecimentos sobre os fatores envolvidos na gênese da ADFF são importantes. Objetivos: documentar a prevalência de ADFF em renais crônicos em hemodiálise. Caracterizar clínica e laboratorialmente os portadores de ADFF em HD e avaliar o estado nutricional, estresse oxidativo e inflamatório. Estudo transversal, amostra de conveniência, envolvendo 183 renais crônicos em hemodiálise no sul do Brasil. Após aplicação dos critérios de exclusão, os pacientes foram separados em dois grupos: portadores de anemia com e sem deficiência funcional de ferro. Foram submetidos a questionário socioepidemiológico, à análise antropométrica e análise laboratorial dos marcadores de anemia, estresse oxidativo, inflamatórios e nutricionais. Análise estatística: programa GraphPad InStat versão 3.1. Foram aplicados os testes: Kolmogorov-Smirnov, qui-quadrado, t de Student e Mann-Whitney. Nível de significância adotado de 5%. Resultados: não houve diferença significativa nos marcadores inflamatórios entre os dois grupos. Houve diferença significativa nos marcadores de anemia e nutrição, significativamente menores nos pacientes com ADFF. Pacientes com ADFF receberam doses mais elevadas de ferro parenteral (p < 0,05). Discussão: ADFF esteve associada a menores valores de marcadores nutricionais, mas não esteve associada a marcadores inflamatórios ou de estresse oxidativo aumentados, como relatado na literatura. Estudos adicionais sobre o tema são necessários.

ABSTRACT

Abstract Avian malaria is one of the most important diseases of captive penguins. We employed morphometric techniques to evaluate hepatic hemosiderosis in rehabilitating wild Magellanic penguins (Spheniscus magellanicus) that were negative (n = 9) or naturally infected by different subgenera of Plasmodium spp. (n = 24), according with: Plasmodium subgenera (Haemamoeba, Huffia, Other lineages, and Unidentified lineages), severity of Plasmodium histopathological lesions, and concurrent diseases, age class (juvenile or adult plumage), sex (male, female or not determined), body score (emaciated, thin, good, excellent, not available), molt, presence or absence of oil contamination upon admission, iron supplementation, and rehabilitation center. The percentage of the area occupied by hemosiderin was called 'Index of Hepatic Hemosiderosis (IHH)'. Plasmodium-positive females presented significantly higher IHH values (17.53 ± 12.95%) than males (7.20 ± 4.25%; p = 0.041). We observed higher levels of congestion (p = 0.0182) and pneumonia (p = 0.0250) severity between Unidentified lineages vs. Huffia. We believe that the hepatic hemosiderosis observed in this study was multifactorial, the result of pathological processes caused by malaria, molting, hemoglobin and myoglobin catabolism during migration, anemia, concomitant diseases, and iron supplementation, all possibly potentiated by decreased liver mass. Further studies are needed to clarify the mechanisms of these hypotheses.


Resumo Malária aviária é uma das mais relevantes doenças em pinguins cativos. Foram aplicadas técnicas morfométricas para avaliar a hemossiderose hepática em pinguins-de-Magalhães (Spheniscus magellanicus ) de vida livre em reabilitação negativos (n = 9) e naturalmente infectados por diferentes subgêneros de Plasmodium spp. (n = 24), quanto a: subgênero de Plasmodium (Haemamoeba , Huffia, Outras Linhagens, e Linhagens não identificadas), severidade das lesões histopatológicas causadas por Plasmodium e doenças concomitantes, faixa etária (plumagem juvenil ou adulta), sexo (macho, fêmea, indeterminado), condição corporal (emaciado, magro, bom, excelente, indisponível), muda, presença/ausência de óleo a admissão, suplementação de ferro, e centro de reabilitação. A porcentagem da área ocupada por hemossiderina foi denominada "Índice de Hemossiderose Hepática (IHH)". Fêmeas Plasmodium -positivas apresentaram IHH significativamente mais elevado que machos, respectivamente, 17,53 ± 12,95% e 7,20 ± 4,25% (p = 0,041). Níveis mais elevados de congestão (p = 0,0182) e pneumonia (p = 0,0250) foram observados entre Linhagens não identificadas vs. Huffia. Possivelmente, a hemossiderose hepática observada nesse estudo seja multifatorial, resultado de processos patológicos causados por malária, muda, catabolismo de hemoglobina e mioglobina durante a migração, anemia, doenças concomitantes e suplementação de ferro, potencialmente intensificados por massa hepática reduzida. Estudos complementares são necessários para esclarecer os mecanismos de tais hipóteses.

ABSTRACT

Background and Objectives@#Iron is an essential element that plays a vital role in a wide variety of cellular processes. But when present in excess concentration in organs, it may increase the risk for liver disease, heart failure, and diabetes. Recently, siderophores, which are iron-chelating agents produced by microorganisms, have attracted tremendous attention because of their strong binding and high selectivity to the ferric form of iron. Thus, the use of siderophore in sequestering excess iron in the body as a form of therapy is very attractive. This study determined the effects of commercially available siderophore in sequestering excess iron in organs such as liver, heart, and pancreas under excess iron conditions. @*Methodology@#First, iron-overload was induced by injecting iron dextran (20 mg) into male ICR mice for three consecutive days. The effects of iron to the liver, heart, and pancreas and the possible sequestration by siderophore were determined by scoring histological sections. The liver iron concentration was also assessed by atomic absorption spectroscopy (AAS).@*Results and Conclusion@#The study showed that iron-overloaded mice exhibited skin hyperpigmentation and hemosiderosis in liver, heart, and pancreas. Significant changes in the liver include hepatomegaly and development of tumor. Iron-overloaded mice had 2,935% increase in liver iron content compared to the salinetreated mice. However, when iron-overloaded mice were treated with either 100 µg or 200 µg siderophore, there was a 77% and 84% decrease in liver iron content, respectively. Moreover, the treatment of ironoverloaded mice with siderophore prevented the development of hemosiderosis, tumor, and structural changes in the tissues studied. The results showed that siderophore can effectively reduce excess iron and organ damage in iron-overloaded mice and can be potentially employed in chelation therapy of iron-overload diseases. Further studies on the possible mechanisms of siderophore aside from decreasing iron excess and lowering organ dysfunction are recommended.

ABSTRACT

Hemosiderosis is characterized by the deposition of excess iron in body tissues. The choroid plexus is an important part of the central nervous system that can be the primary site of iron overload. T2*-weighted gradient echo (GRE) sequence provides high sensitivity for demonstrating cerebral microhemorrhagic foci and iron deposition. In the present study, we describe the case of a 15-year-old boy with acute lymphoblastic leukemia, in whom repeated transfusion led to iron accumulation in the brain. GRE sequence effectively demonstrated hemosiderin deposition in the choroid plexus.

ABSTRACT

ABSTRACT Idiopathic pulmonary hemosiderosis is a potentially fatal disease that results from episodes of alveolar hemorrhage of unknown origin. The clinical spectrum is varied, and anemia may constitute the only manifestation of illness, preceding other signs and symptoms by several months. We present the case of a 4 year-old child presenting with fever, vomiting and prostration, associated with pallor. He had microcytic and hypochromic anemia refractory to iron therapy. Gastrointestinal bleeding was ruled out after negative extensive etiological investigation. Subsequently, pulmonary infiltrates suggestive of alveolar hemorrhage were observed in the chest radiography. The cytological exam of the bronchoalveolar lavage showed hemosiderin-laden macrophages. After the etiological study, the diagnosis of idiopathic pulmonary hemosiderosis was made by exclusion. He was initiated on corticosteroid therapy, later associated to an immunosuppressive agent, with subsequent correction of anemia and of the radiological pattern. The patient is currently asymptomatic.


RESUMO A hemossiderose pulmonar idiopática é uma doença potencialmente fatal que cursa com episódios de hemorragia alveolar de etiologia desconhecida. As manifestações clínicas são variadas, e a anemia pode constituir o único sinal de doença, precedendo em vários meses os outros sinais e sintomas. Apresenta-se o caso de criança de 4 anos, com febre, vômitos e prostração, associados à palidez. Apresentava anemia microcítica e hipocrômica, refratária à terapêutica com ferro. A hipótese diagnóstica de sangramento gastrintestinal foi excluída, após investigação etiológica extensa, inconclusiva. Posteriormente, em radiografia torácica, foram observados infiltrados sugestivos de hemorragia alveolar. O exame citológico do lavado broncoalveolar mostrou macrófagos com depósitos de hemossiderina. Após estudo etiológico, assumiu-se, por exclusão, o diagnóstico de hemossiderose pulmonar idiopática. Foi iniciada terapêutica com corticoides, associada posteriormente a imunossupressor, com correção subsequente da anemia e do padrão radiológico, encontrando-se, atualmente, assintomático.

ABSTRACT

El patrón en arcoiris ha sido un tema controvertido, dado que en un principio se planteó como un patrón dermatoscópico específico asociado al diagnóstico de Sarcoma de Kaposi. Sin embargo, esta asociación ha sido cuestionada por diversos reportes que han evidenciado la presencia de este patrón dermatoscópico en otro tipo de lesiones, tales como, otros tumores vaculares, cicatriz hipertrófica, angioqueratoma, dermatitis por estasis, pseudo-Kaposi (acroangiodermatitis), melanoma, liquen plano, dermatofibroma hemosiderótico, entre otros. Se ha propuesto que este efecto se genera por la absorción, difracción y difusión de la luz polarizada y su interferencia con diferentes componentes vasculares y fibrosos de la dermis más que por algún hallazgo histopatológico específico. Presentamos el primer caso con registro fotográfico de dermatofibroma hemosiderótico con presencia de un 'patrón irisado' en la dermatoscopía.


The dermoscopic 'rainbow pattern' has been a controversial issue; it was initially proposed as a specific dermatoscopic pattern associated with Kaposi's Sarcoma. However, this has been questioned by several reports that have shown the presence of this dermoscopic pattern in a wide variety of lesions such as other vascular tumors, hypertrophic scars, angiokeratoma, stasis dermatitis, pseudo-Kaposi acroandgiodermatitis), melanoma, lichen planus, and hemosiderotic dermatofibroma, among others. It has been proposed that this effect is generated by the absorption, diffraction and diffusion of polarized light and its interference with different vascular and fibrous components of the dermis, rather than being caused by a specific histopathologic finding. We present the first photographically recorded case of hemosiderotic dermatofibroma, characterized by the presence of a rainbow pattern in dermoscopy.

Introducción: A hemisferectomía es un procedimiento valioso en el tratamiento de trastornos convulsivos causados por desordenes hemisféricos unilaterales. El hemisferectomía anatómica se ha utilizado para este fin desde 1938, sin embargo, se abandonó este procedimiento después de informes de complicaciones postoperatorias causadas por hemosiderosis superficial, ependimitis e hidrocefalia obstructiva. Así que, se ha mostrado en la literatura modificaciones en las indicaciones y técnicas de hemisferectomía anatómica cuya finalidad es la de reducir la incidencia de esta complicación sin dejar de lograr control de las convulsiones. Sobre la base de la literatura, la hemisferectomía mejora la calidad de vida de los pacientes que tiene la indicación para realizar este procedimiento, ya que permite reducir la frecuencia de las convulsiones, si tónica o átona, tónico-clónicas Objetivo: El objetivo de esta revisión de la literatura es discutir los detalles técnicos, modalidades, riesgos, complicaciones, resultados y de pronóstico de hemisferectomía basado en la revisión crítica de la literatura. Casuística y Métodos: Se realizó la consulta bibliográfica, utilizando la base de datos MEDLINE, LILACS, SciELO, que utiliza el lenguaje como criterios de selección, la elección de los artículos recientes preferiblemente en portugués, español o inglés. Conclusión: Según las referencias, hemisferectomía es un procedimiento con buen resultado para las personas con convulsiones derivadas cuando está indicado para casos seleccionados y la tasa de éxito no es proporcional a la extensión de la resección del tejido neuronal. A mayor resección puede o no reducir la frecuencia de las crisis, sin embargo, la incidencia de la morbilidad puede ser mayor.


Background: The hemispherectomy is a valuable procedure in the management of seizure disorders caused by unilateral hemispheric disease. The anatomical hemispherectomy has been used for this purpose since 1938, however, it was abandoned after reports of postoperative complications caused by superficial hemosiderosis, ependymitis and obstructive hydrocephalus. So that, it has been showed modifications in the techniques of hemispherectomy whose the purpose is reduce the incidence of this complications while still achieving seizure control. Based on literature, the hemispherectomy improves the quality of life of patients that has the indication to perform this procedure because it allows reducing the frequency of seizures, whether tonic or atonic, tonic-clonic. Aim: The aim of this literature review is discuss the indications, technical details, modalities, risks, complications, results as well de prognosis of callosotomy based on critical literature review and the authors experience. Casuistry and Methods: It was performed bibliographical consultation, using the databases MEDLINE, LILACS, SciELO, utilizing language as selection criteria, choosing preferably recent articles in Portuguese, Spanish or English. Conclusion: According to references, the functional hemispherectomy has a good outocome for those with seizures arisin when indicated to selected cases and the success rate is not proportional to the extent of neuronal tissue resection. So that, a greater resection cannot necessarily reduce the seizure frequency, however the morbidity may also be larger.

ABSTRACT

Abstract: We report a rare clinical case of hemosiderotic dermatofibroma in a 36-year-old female patient. The main dermatoscopic finding was represented by homogeneous blue-gray pigmentation. The aim of this report is to demonstrate the rarity of the lesion and the dermatoscopic importance it assumes by sharing a blue-gray homogeneous pattern with other benign and malignant lesions.

ABSTRACT

This article reports 4 girls with clinical manifestations of recurrent cough and anemia. The age of onset was less than 4 years, and three of them had shortness of breath. None of them had acute hemoptysis. All the girls had positive results of hemosiderin test for bronchoalveolar lavage fluid. As for imaging examination, 3 patients had ground-glass opacity, and 1 had interstitial change. Three girls were given the treatment for idiopathic pulmonary hemosiderosis and had no response. Selective bronchial arteriography was performed for the 4 girls and found bronchial artery to pulmonary circulation shunt (BPS). After they were diagnosed with BPS, they were given transcatheter embolization. The girls were followed up for half a year after surgery, and none of them was readmitted due to "cough and anemia". BPS manifests as abnormal shunt between the bronchial artery and the pulmonary artery/vein and has unknown causes. It is rare in children and should be considered for children who were thought to have idiopathic pulmonary hemosiderosis and had poor response to corticosteroid therapy.

ABSTRACT

La osificación pulmonar es un hallazgo poco usual, generalmente asintomático, que se reporta como incidental en biopsias de pulmón. Asimismo, la hemosiderosis pulmonar idiopática es una causa poco frecuente de infiltración pulmonar. Se presenta el caso de un hombre de 64 años con síntomas respiratorios crónicos, en quien se detectaron estas dos condiciones en el estudio histopatológico.


Pulmonary ossification is a rare and usually asymptomatic finding reported as incidental in lung biopsies. Similarly, idiopathic pulmonary hemosiderosis is a rare cause of pulmonary infiltrates. We report the case of a 64-year old man with chronic respiratory symptoms in whom these two histopathological findings converged

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the etiology and clinical manifestation of hemoptysis in children.</p><p><b>METHOD</b>A retrospective analysis was performed for 106 cases of hemoptysis who were admitted to The Second Affiliated Hospital & Yuying Children's Hospital of Wenzhou Medical University from January 2005 to December 2014.The clinical information including laboratory tests and image data were collected and analyzed.</p><p><b>RESULT</b>A total of 106 patients (50 males and 56 females) were identified. The median age was 9.1 years (range 2 months to 18 years). Pneumonia (35, 31.1%) was the most common etiology of hemoptysis, which included bacterial pneumonia (27 cases), mycoplasmal pneumonia(4 cases), chlamydial pneumonia (3 cases), and influenza pneumonia(1 case). Other causes included bronchitis(15, 14.2%), pulmonary tuberculosis (11, 10.4%), bronchiectasis (11, 10.4%), diffuse alveolar hemorrhage (8, 7.5%), idiopathic pulmonary hemosiderosis(6, 5.7%), cardiovascular dysplasia(6, 5.7%), pulmonary contusion (4, 3.8%), foreign body in bronchus (2, 1.9%), allergic bronchopulmonary aspergillosis (2, 1.9%). Eighty-six patients manifested mild hemoptysis; moderate and massive hemoptysis were found in nine and eleven patients, respectively. Pneumonia accounted for 33.7% of mild hemoptysis and 45.5% of massive hemoptysis were due to bronchiectasis; 80.2% were treated with antibiotics and 41.5% were given hemostatic agents; 8.5% received lobectomy. Ninety-six patients (90.6%) were cured and parents gave up treatment in 4 cases (3.8%). Six patients (5.7%) suffered from recurrent hemoptysis.</p><p><b>CONCLUSION</b>Hemoptysis mainly occurred in children who were older than 6 years, the most common cause of hemoptysis was respiratory tract infection. In most cases, the amount of hemoptysis was small and the overall prognosis was good.</p>

ABSTRACT

Idiopathic pulmonary hemosiderosis (IPH) is a rare respiratory disease with an unknown etiology, and is diagnosed with laboratory, radiology, and pathology tests. Chief complaints of IPH include hemoptysis, cough, and dyspnea. Since it is considered an immune-mediated disease, the first line of treatment is systemic corticosteroid therapy. The three cases reported here showed a decrease in ferritin level and improvement in the hemoglobin level with prednisolone treatment. However, long-term corticosteroid therapy may cause several side effects, particularly growth retardation and obesity, which can affect growing children. In the present study, all patients had cushingoid symptoms and obesity. Therefore, we switched to deflazacort (DFZ), which has lesser side-effects of weight gain. This report describes clinical courses of the disease and comparison of body mass index of three patients with IPH who took DFZ instead of prednisolone. DFZ was effective for IPH, and is useful for weight gain reduction.
