Evidencia actual sobre características demográficas en mastitis granulomatosa idiopática

Introducción: La mastitis granulomatosa idiopática es una enfermedad crónica benigna, rara y de etiología desconocida; tiende a confundirse con otras enfermedades debido a síntomas similares. Este estudio pretende identificar y cuantificar las características demográficas, los antecedentes ginecoobstétricos relevantes y las manifestaciones clínicas prediagnósticas de esta enfermedad Metodología: Se realizó una revisión sistemática con análisis agrupado de datos tipo meta análisis. Se utilizó una estrategia de búsqueda en PubMed. Todos los estudios relacionados con la definición, manifestaciones clínicas, diagnóstico, tratamiento y pronóstico de la mastitis granulomatosa idiopática fueron elegibles. Las variables de interés fueron edad, país, antecedente de contracepción hormonal, tiempo de evolución, tiempo desde el último embarazo, diagnóstico inicial, y manifestaciones clínicas previas a la consulta. No hubo restricción en fechas de publicación. Resultados: Fueron incluidas 641 mujeres con diagnóstico de MGI reportadas en 68 publicaciones que cumplieron los criterios de selección. La edad media fue 35.9 años, 14.1% de ellas estaba embarazada o lactando, el antecedente de consumo de anticonceptivos hormonales fue 21% y el tiempo promedio desde el último parto fue de 3.9 años. La afectación ocurre principalmente en mama izquierda y en cuadrante superoexterno. El cáncer de mama y el absceso mamario son diagnósticos diferenciales en la consulta. Discusión: El diagnóstico de MGI es un reto para el ginecólogo desde la consulta inicial. Debido a que sus manifestaciones clínicas no son específicas, su diagnóstico parece apuntar a la necesidad de un proceso de descarte de otras patologías más frecuentes e incluso de peor pronóstico.

Incidência e evolução da polipose nasal em crianças e adolescentes com fibrose cística

Nasal polyps are a clinical sign of alert for investigating Cystic Fibrosis (CF). Aims: To study the incidence of nasal polyps in children and adolescents with cystic fibrosis, its possible association with age, gender, clinical manifestations, genotype and sweat chlorine level, and its evolution with topical steroid therapy. Methods: Clinical symptoms, sweat chlorine level and genotype were studied in 23 cystic fibrosis patients. Nasal polyps were diagnosed by nasal endoscopy and treated with topical steroids during 6 months, followed by a second nasal endoscopy. Fisher test was used for statistical analysis. Results: Nasal polyps were found in 39.1% of the patients (five bilateral, four unilateral), all older than six years, recurrent pneumonia in 82.6%, pancreatic insufficiency in 87% and malnutrition in 74%. No association was seen between nasal polyps and sweat chlorine level, genotype, clinical sings of severity and nasal symptoms. Seven patients improved in their nasal polyps with topical steroids, six showed complete resolution. Conclusion: The study showed a high incidence of nasal polyps in older children, who span the entire range of clinical severity, even in the absence of clinical nasal symptoms. Topical steroid therapy showed good results. An interaction among pediatricians and otolaryngologists is necessary for diagnosis and follow-up. 2008 © Revista Brasileira de Otorrinolaringologia.

Association between systemic corticosteroids and outcomes of intensive care unit-acquired pneumonia

Objective: The use of corticosteroids is frequent in critically-ill patients. However, little information is available on their effects in patients with intensive care unit acquired pneumonia. We assessed patients' characteristics, microbial etiology, inflammatory response, and outcomes of previous corticosteroid use in patients with intensive care unit acquired pneumonia. Design: Prospective observational study. Setting: Intensive care units of a university teaching hospital. Patients: Three hundred sixteen patients with intensive care unit acquired pneumonia. Patients were divided according to previous systemic steroid use at onset of pneumonia. Interventions: None. Measurements and Main Results: Survival at 28 days was analyzed using Cox regression, with adjustment for the propensity for receiving steroid therapy. One hundred twenty-five (40%) patients were receiving steroids at onset of pneumonia. Despite similar baseline clinical severity, steroid treatment was associated with decreased 28-day survival (adjusted hazard ratio for propensity score and mortality predictors 2.503; 95% confidence interval 1.176-5.330; p = .017) and decreased systemic inflammatory response. In post hoc analyses, steroid treatment had an impact on survival in patients with nonventilator intensive care unit acquired pneumonia, those with lower baseline severity and organ dysfunction, and those without etiologic diagnosis or bacteremia. The cumulative dosage of corticosteroids had no significant effect on the risk of death, but bacterial burden upon diagnosis was higher in patients receiving steroid therapy. Conclusions: In critically-ill patients, systemic corticosteroids should be used very cautiously because this treatment is strongly associated with increased risk of death in patients with intensive care unit acquired pneumonia, particularly in the absence of established indications and in patients with lower baseline severity. Decreased inflammatory response may result in delayed clinical suspicion of intensive care unit acquired pneumonia and higher bacterial count. (Crit Care Med 2012; 40:2552-2561)

Ruolo dell'Infliximab nella terapia della colite ulcerosa moderato-severa

Background: Almost 10-15% of patients with active Ulcerative Colitis are refractory to conventional therapy. Infliximab is a treatment of proven efficacy in this group of patients. Aims: To evaluate the role of Inliximab in inducing and maintaining remission in patients with chronically active moderate-severe Ulcerative Colitis. Materials and methods: 53 patients were enrolled, 47 patients entered the study and were treated with a dose of 5 mg/kg. The remission was evaluated through endoscopy and clinical criteria. (Mayo Score). The primary endpoint were clinical and endoscopic remission in moderate-severe Ulcerative Colitis refractory to standard therapy, the secondary out point was the maintenance of remission in the long period. Results: 47 patients started the study, 43 completed the study, 4 dropped out for worsening disease or adverse events; 27 patients were treated with 3 infusions, 9 patients with 4 infusions, 7 patients with > o = 5 infusions. 34 /47 patients (72.3%) were responders 12 (25.5%) improved their symptoms, 22 ( 46.8%) were in remission after the treatment. Among the responders, 21/34 (61.8%) stopped the steroid therapy after 3 infusions, the others reduced the dose or maintained just topic therapy. 13/47 patients (27.7%) were non responders (p <0.001). After 3 months all 22 patients which had reached remission maintained low Mayo Score; 10/12 (83.3%) patients with clinical response maintained their low score, 2 relapsed . Conclusions: Infliximab is a valid therapy for the treatment of Ulcerative Colitis and can avoid surgery in selected patients.

Mastocitosi cutanee: il mastocitoma in età pediatrica

Background: Mastocytosis is a rare disease involving mast cells (MC) and their CD34+ progenitors. According to the WHO consensus classification, cutaneous mastocytosis (CM) is considered a benign disease confined to the skin, preferentially seen in young children with a marked tendency to regress spontaneously. Aim of our study was the long-term assessment of the outcome of solitary (SM) and multiple (MM) mastocytomas in a pediatric population. Materials and methods: From January 1996 to December 2010, 241 pediatric patients with a diagnosis of CM were followed-up at the outpatient division of pediatric dermatology of the University of Bologna. We focused our retrospective evaluation on patients affected by SM or MM. We collected, through the analysis of medical records and with a telephone questionnaire for patients and their families, information on clinical aspects of the disease evolution and on the efficacy of topical steroid therapy. Results: Over the 241 considered patients we recorded: SM or MM in 176 (73%) pts., urticaria pigmentosa in 53 (22%) pts., telangiectasia macularis eruptiva perstans in 9 (4%) pts., diffuse CM in 2 (0,9%) pts. and polymorph CM in 1 (0,4%) pt. On 176 children affected by SM or MM (97 M vs. 79 F), 130 (74%) patients were followed-up with a mean of 56,3 (r. 4-142) months. A satisfactory outcome was recorded in 99 (76%) cases of whom 52 (53%) treated with topic steroids. Mean time to complete regression was 16.4 m. on treated patients vs. 34.7 m. on non treated patients (p=0,001). Conclusions: From our study emerged that resolution of the disease is independent from therapy, but the time to regression and to complete recovery of the coetaneous lesions is faster and favored by the application of topic steroid with an improvement of the quality of life for children and their families.

Decorso delle coliti severe: un confronto tra colite ulcerosa e di Crohn

Pochi sono i dati disponibili sul decorso clinico della malattia di Crohn del colon severa(CD). L'obiettivo è quello di descrivere il decorso clinico della colite di Crohn severa (CC) in una coorte di pazienti isolata con CD del colon o ileocolica, e di confrontarlo con il decorso clinico di pazienti affetti da colite ulcerosa severa (UC). 34 pazienti con CC severa sono stati identificati retrospettivamente nella nostra coorte di 593 pazienti ricoverati (2003-2012) attraverso la valutazione di CDAI score e HBI. 169 pazienti con UC severa sono stati identificati retrospettivamente in una coorte di 449 pazienti ricoverati (2003-2012) attraverso la valutazione del score di Lichtiger e di Truelove-Witts. Abbiamo valutato questi risultati: risposta agli steroidi, risposta ai farmaci biologici, tasso di colectomia acuta, tasso di colectomia durante il follow-up, megacolon e tasso di infezione da citomegalovirus. Non abbiamo trovato differenze significative nella risposta agli steroidi e biologici, della percentuale di infezione da citomegalovirus e di megacolon, mentre il tasso di colectomia in acuto è risultato essere maggiore nei pazienti con CC rispetto ai pazienti con UC; anche la differenza tra i tassi di colectomia alla fine del follow-up è risultata non significativa. Con l'analisi univariata la giovane età alla diagnosi è associata ad un aumentato rischio di colectomia in assoluto (p = 0,024) e in elezione (p = 0.022), ma non in acuto. Il tasso globale di colectomia nei pazienti con CC severa è superiore a quella dei pazienti con UC severa , ma questo dato non è supportato da una diversa risposta clinica alla terapia steroidea o terapia di salvataggio con biologici. Il vero decorso clinico della colite di Crohn severa necessita di essere chiarito da studi prospettici che includano un numero maggiore di pazienti con questo sottogruppo di malattia.

Uveitic glaucoma and Rosai-Dorfman disease (sinus histiocytosis)

PURPOSE: To report a novel association of uveitic glaucoma with Rosai-Dorfman disease. METHODS: Case report. RESULTS: A 67-year-old Caucasian woman presented with a chronic bilateral granulomatous uveitis which did not respond to conventional topical steroid therapy. She also had raised intraocular pressures, glaucomatous optic disc changes and diffuse nodular fibrous skin lesions. Subsequent skin biopsy immuno-cytochemistry showed S-100 staining, consistent with Rosai-Dorfman disease. The uveitis and glaucoma were highly resistant to standard medical treatments, but completely resolved together with the systemic features of the disease after six months. CONCLUSIONS: Rosai-Dorfman disease has not previously been reported to cause uveitic glaucoma and should be considered in non-responsive cases presenting with a rash. The disease is entirely self-limiting and early diagnosis may therefore avoid unnecessary trabeculectomy and/or systemic immune suppression.

[Acute asthma attacks in childhood]

The diagnosis of an acute asthmatic attack in a child is made on a clinical basis. The severity of the exacerbation can be assessed by physical examination and measurement of the transcutaneous oxygenation saturation. A blood gas analysis can be helpful in this assessment. A child with a severe asthma exacerbation should be promptly referred to an emergency department of a hospital. Oxygen should be given to keep the oxygen saturation above 92% and short-acting, selective beta-2 agonists should be administered. Beta-2 agonists can be delivered by intermittent nebulization, continuous nebulization or by metered dose inhaler (MDI) with a spacer They can also be given intravenously in patients who are unresponsive to escalating therapy. The early administration of systemic corticosteroids is essential for the management of acute asthma in children. When tolerated, systemic corticoseroids can be given orally but inhaled corticosteroids are not recommended. Oxygen delivery, beta-2 agonists and steroid therapy are the mainstay of emergency treatment. Hypovolemia should be corrected either intravenously or orally. Administration of multiple doses of ipratropium bromide has been shown to decrease the hospitalization rate in children and adolescents with severe asthma. Clinical response to initial treatment is the main criterion for hospital admission. Patients with failure to respond to treatment should be transferred to an intensive care unit. A critical aspect of management of the acute asthma attack in a child is the prevention of similar attacks in the future.

Predictors for hospitalization and outpatient visits in patients with inflammatory bowel disease: results from the Swiss Inflammatory Bowel Disease Cohort Study

OBJECTIVES Patients with inflammatory bowel disease (IBD) have a high resource consumption, with considerable costs for the healthcare system. In a system with sparse resources, treatment is influenced not only by clinical judgement but also by resource consumption. We aimed to determine the resource consumption of IBD patients and to identify its significant predictors. MATERIALS AND METHODS Data from the prospective Swiss Inflammatory Bowel Disease Cohort Study were analysed for the resource consumption endpoints hospitalization and outpatient consultations at enrolment [1187 patients; 41.1% ulcerative colitis (UC), 58.9% Crohn's disease (CD)] and at 1-year follow-up (794 patients). Predictors of interest were chosen through an expert panel and a review of the relevant literature. Logistic regressions were used for binary endpoints, and negative binomial regressions and zero-inflated Poisson regressions were used for count data. RESULTS For CD, fistula, use of biologics and disease activity were significant predictors for hospitalization days (all P-values <0.001); age, sex, steroid therapy and biologics were significant predictors for the number of outpatient visits (P=0.0368, 0.023, 0.0002, 0.0003, respectively). For UC, biologics, C-reactive protein, smoke quitters, age and sex were significantly predictive for hospitalization days (P=0.0167, 0.0003, 0.0003, 0.0076 and 0.0175 respectively); disease activity and immunosuppressive therapy predicted the number of outpatient visits (P=0.0009 and 0.0017, respectively). The results of multivariate regressions are shown in detail. CONCLUSION Several highly significant clinical predictors for resource consumption in IBD were identified that might be considered in medical decision-making. In terms of resource consumption and its predictors, CD and UC show a different behaviour.

IgA-Nephropathie und Purpura Schönlein-Henoch - ein breites Spektrum

IgA nephropathy is the most common glomerulonephritis in Europe. The disease has been discovered in 1968 in Paris by Jean Berger at the Necker-Children's Hospital. Diagnosis is made by kidney biopsy and requires the presence of mesangial deposits of IgA. This form of glomerulonephritis can be seen in children and adults. In childhood, it most frequently presents within the context of Schoenlein-Henoch purpura. In adulthood, the most common form is limited to the kidney. Schoenlein-Henoch purpura can be seen in adults and manifests as a very aggressive vasculitis, usually in the context of a specific drug intake. The underlying pathophysiological concept today is an insufficient glycosylation of the IgA1 hinge region triggering the formation of autoantibodies against this site. Therapeutic options for the disease are limited. Important is optimal blood pressure control. Selected patients will profit from steroid therapy.

Asma, abitudini e stile di vita "Analisi retrospettiva di un campione di pazienti asmatici seguito in ambulatorio di terzo livello"

Growing evidence suggest the importance of different environments in promoting the pathogenesis and/or exacerbation of asthma. Indoor air pollution is a major contributor to human exposure, since people spend up to 90% of their day indoors. Apart from active smoking, indoor pollution is considered one of the major preventable risk factors of chronic respiratory diseases. The professional activity can also be dangerous because it exposes the subject to environments that can promote the onset of asthma or worsening of the latter in those already affected. Even bad habits such as incorrect diet, lead to more difficulty in controlling their disease. However asthma is a multifactorial disease in nature so it is not easy to distinguish the role of occupational exposure, pollution and normal habits such as smoking, nutrition, sports, etc. This retrospective study was conducted on a sample of asthma patients residing in the metropolitan area of Parma. 116 patients were selected among those who are followed up at least two years at the Asthma outpatient Clinic of Parma University Hospital. The sample in question is therefore closely controlled and monitored; it comes to patients who are well educated on the control of their disease, are able to take appropriate measures to minimize the symptomatology. With this tight approach is proposed to minimize the effect of confounding and then traced with greater certainty the possible cause of the failure to control the disease. For this purpose, each patient was subjected to regular checkups; we took as a reference the period of time between April and October 2015. During each visit, in addition to general data for each patient, we were collected personal information about their habits and way of life through a validated questionnaire delivered and completed by the patient during the visit in the presence of the permanent staff. The questionnaire covers mainly the qualification of the patient, its possible occupational exposure, his home, with information about nearby traffic, time spent outside, physical activity (place and time), exposure to chemicals, exposure to various fumes (fireplace or stove) and cigarette smoke, comorbidities and any drugs taken during the visits considered. Regarding the respiratory conditions of patients during every examination we were considered: Asthma Control Test (a test performed by patients to assess the state of the disease during the month preceding the test), the measurement of exhaled nitric oxide (FeNO) as an index of airways inflammation, measuring the resistance level of small airways (R5-R20) and some spirometric values observed in experiment; in particular the forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1), FEV1/FVC ratio, forced expiratory flow rate over the middle 50% of the FVC (FEF25–75) and FEF25-75/FVC were recorded. The sample has been studied considering both the changes of the respiratory parameters for every patient in their examinations, and the respiratory parameters of all the examinations took as a whole in relation with the variables considered. From the results obtained, the patients are clinically stable; their adopted lifestyle and the exposure to possible sources of outdoor pollution, seems not affect the overall control of their disease. Some findings of our study are of interest. First, the subjects who carry a steroid therapy show a clinical worst, as revealed by the decrease of most spirometric indices, particularly FEF25, FEF75, FEF25-75 and R5-R20; also, the presence of comorbidities and the subsequent intake of other drugs, in addition to normal therapy for asthma, seem to be conditions associated with poorer performance in the functional respiratory parameters in particular FEV1/FVC, FEF75 and FEF25-75. Spirometric indexes that are down are mainly those related to obstruction imposed on small airways; this suggests a neglect to the latter on the contrary should be further explored and treated accordingly. It is also observed that both patients are overweight than those living on the lower floors and/or who have the most windows exposed to traffic, showed a decrease of pulmonary function, especially those relate to an obstruction at the small airways level. In conclusion, our results provided the evidence that a most appropriate therapy, specific to reach the small airways, associated with a healthy lifestyle, can help improve the management of asthma.

Hashimoto’s Encephalopathy: An Unusual Cause of Autoimmune Encephalopathy in a Clinically and Biochemically Euthyroid Patient

Objectives: To highlight the occurrence of Hashimoto’s encephalopathy – a steroid-responsive encephalopathy associated with elevated antithyroid antibodies. Material and methods: We describe a clinically and biochemically euthyroid patient with an encephalopathy presenting with headache, mild confusion and personality changes for 6 weeks and tonic–clonic seizures upon admission Results: There was no obvious infective or metabolic cause. The patient had a high titre of antithyroid antibodies and responded to steroid therapy. Conclusion: This uncommon disease needs to be considered in patients presenting with neurological symptoms that remain unexplained after routine standard investigations, even when the patient is euthyroid. Early diagnosis is important, as this is a treatable condition.

Eosinophilic Pneumonia Associated with Rheumatoid Arthritis: Description of a Case Report and Review of the Literature

Rheumatoid arthritis (RA), a systemic inflammatory disease, may induce pulmonary manifestations. We describe a case of longstanding RA presenting with eosinophilic pneumonia (EP). Rare case reports of tissue eosinophilia involving isolated organs in the setting of RA exist in the literature. It has been shown that the production of proinflammatory cytokines activates different cell group and can simultaneously play a role in RA and induce eosinophils infiltration in target tissue. An appropriate lowest possible dosage of steroid therapy is essential, whereas EP may be a rare subset of pulmonary involvement in RA.

Anti-Signal Recognition Particle Myopathy in a Geriatric Patient

Anti-signal recognition particle (SRP) myopathy is a rare idiopathic inflammatory myositis that usually affects middle-age women, and is characterized by rapidly progressive proximal and symmetrical muscle weakness, elevated creatine kinase levels, severe necrotizing immune-mediated myopathy, presence of anti-SRP autoantibodies and poor response to steroid therapy. We report a geriatric case of a previously independent patient, presenting with slow onset of proximal paraparesis, myalgia and severe gait impairment. The patient was treated with steroid and azathioprine, with laboratory and pain response but modest muscle strength improvement. The clinical presentation of this unusual patient was atypical, which hampered the correct diagnosis.
