Translation and validation of the Simplified Psoriasis Index (SPI) into Brazilian Portuguese

AbstractBackground: The Simplified Psoriasis Index is a tool that assesses the current severity, psychosocial impact, past history and interventions in patients with psoriasis through separate components. Two versions are available, one in which the current severity of the disease is evaluated by the patient themselves and another by the physician.Objectives: Translate the Simplified Psoriasis Index into Brazilian Portuguese and verify its validity.Methods: The study was conducted in two stages; the first stage was the translation of the instrument; the second stage was the instrument's validation.Results: We evaluated 62 patients from Complexo Hospitalar Santa Casa de Porto Alegre and Hospital Universitârio de Brasilia. The Simplified Psoriasis Index translated into Portuguese showed high internal consistency (Cronbach test 0.68).Study limitations: Some individuals, because of poor education, might not understand some questions of the Simplified Psoriasis Index.Conclusions: The Brazilian Portuguese version of the Simplified Psoriasis Index was validated for our population and can be recommended as a reliable instrument to assess the patients with psoriasis.

Liver retransplantation in adults: a 20–year experience of one center in southern Brazil

Introduction. Liver retransplantation (LReTx) is the therapeutic option for hepatic graft failure. Survival after LReTx is poorer than after primary liver transplantation. Given the organ shortage, it is essential to optimize the use of this resource.Objective. To evaluate rates, indications and patient survival after LReTx and identify factors associated with mortality following LReTx.Material and methods. We conducted a retrospective cohort study of all adults undergoing LReTx based on registry data from the Liver Transplantation Group (Complexo Hospitalar Santa Casa de Porto Alegre), southern Brazil.Results. Between June 16, 1991 and July 19, 2011, 824 patients underwent 866 liver transplants. Forty-two procedures corresponded to LReTx (4.8% of all liver transplants performed). Thirty-eight patients who underwent a single LReTx procedure were included in this study. The leading indication for LReTx was hepatic artery thrombosis (HAT) (31.6%), followed by primary nonfunction (PNF) (18.4%). The main indication for early LReTx was PNF (58.3%) and for late LReTx was HAT (38.5%). During the follow-up period, 26 patients (68.4%) died after LReTx. Patient survival at 1 and 3 years after LReTx was 44.7% and 44.7%, respectively. Patients infected with hepatitis C virus, serum albumin < 2.5 g/dL and receiving mechanical ventilation immediately before LReTx had a significantly lower survival rate than the other patients.Conclusion. Considering the increased mortality when the graft loss is delayed, it is necessary to define the minimum acceptable results to indicate LReTx and identify the patients who would most benefit from this treatment.

Aplicabilidade da escala London Chest Activity of Daily Living em pacientes em lista de espera para transplante de pulmão

OBJECTIVE: To evaluate the applicability of the London Chest Activity of Daily Living (LCADL) scale in patients on the waiting list for lung transplantation. METHODS: This was a cross-sectional study, conducted between May and September of 2010, involving 26 male and female patients on the waiting list for lung transplantation and treated at the Pulmonary Rehabilitation Program in the Complexo Hospitalar Santa Casa de Misericórdia de Porto Alegre, located in the city of Porto Alegre, Brazil. We evaluated the patients using the six-minute walk test (6MWT) and pulmonary function tests. We also obtained the LCADL scores, as well as the modified Borg scale scores for sensation of dyspnea and leg fatigue. Cronbach's alpha coefficient was used to determine the internal consistency of the LCADL scale. Linear regression analysis was used in order to identify associations between the total LCADL score (expressed as a percentage) and the variables studied. RESULTS: According to the LCADL scale results, 69% of the patients reported that the performance of their activities of daily living was significantly impaired by their dyspnea. The internal consistency of the LCADL scale was 0.89. After adjusting for age and FEV1, we found that the total LCADL scale score showed statistically significant negative associations with the six-minute walk distance (β = −0.087; p < 0.001) and the six-minute walk work (β = −0.285; p < 0.001). CONCLUSIONS: Our findings suggest that the LCADL scale is a useful tool for assessing patients on the waiting list for lung transplantation.

Immunohistochemical expression of aromatase and estrogen, androgen and progesterone receptors in normal and neoplastic human meningeal cells

Evidence suggests that sex hormones may play a role in the tumorigenesis of meningiomas, and studies have demonstrated the expression of hormone receptors in these tumors. Aromatase expression has been detected in several normal tissues, including neurons in the CNS, and tumor tissues. We aim to assess the expression of aromatase (ARO) and of progesterone receptor (PR), estrogen receptor (ER) and androgen receptor (AR) in both normal and neoplastic meningeal cells. A cross-sectional study was conducted with 126 patients diagnosed with meningioma (97 women and 29 men; mean age, 53.6 years) submitted to neurosurgery at Hospital São José, Complexo Hospitalar Santa Casa de Porto Alegre, southern Brazil. Control sections of normal meningeal cells, 19 patients, were obtained by evaluating the arachnoid tissue present in the arachnoid cyst resected material. Immunohistochemistry was applied to assess ARO, PR, ER and AR. Aromatase expression was detected in 100% of the control patients and in 0% of the patients with meningioma. ER was present in 24.6% of the meningiomas and in 0% of the controls, AR in 18.3% of the meningiomas and in 0% of the controls, and PR in 60.3% of the meningiomas and in 47.4% of the controls. A positive association was observed between the presence of AR and ER (OR 3.7; P = 0.01) in meningiomas. There were no significant differences in the presence of hormone receptors between meningioma histological subtypes. PR expression in women with meningioma was significantly higher than that found in men (OR 2.3; P = 0.08). Behavior pattern differences observed between aromatase expression, present in normal tissues and absent in meningiomas, and estrogen and androgen hormone receptors, absent in normal tissues and present in meningiomas, suggest that there is heterogeneity in modulation by sex steroids in the development of these tumors.

Processos expansivos orbitoesfenoidais: estudo anatomopatológico de 82 casos

To describe the orbito-sphenoidal expansive processes diagnosed at the Anatomo-Pathological Laboratory of the Fundação Faculdade Federal de Ciências Médicas de Porto Alegre - Complexo Hospitalar Santa Casa de Porto Alegre during a period of 15 years, evaluating their relative frequencies among other tumoral processes. We performed a statistical analysis of all orbital tumors with anatomicopathological diagnosis from January 1968 to December 1982, comparing the frequency of orbital tumors with the total number of tumors diagnosed at this Laboratory in a period of 5 years. Eighty-two cases were diagnosed of expansive processes involving the orbit in 15 years - 20.7% of the total (17 cases) affecting children (up to 14 years-old) and the remaining 79.3% (65 cases) affecting adults. Children presented more frequently optic nerve gliomas (4 of 6 cases 66.6%), retinoblastomas (4 cases - 100%) and rhabdomyosarcomas (3 of 4 cases - 75%). Less frequent diseases in children were optic nerve meningioma, neurofibroma, inflammatory pseudotumor, chronic dacryoadenitis, neuroma and chronic inflammatory process. The adult population presented more cases of basal cell carcinomas (18 cases), squamous cell carciomas (12 cases), meningiomas (10 cases), choroidal malignant melanoma (3 cases) and lacrimal gland tumors (7 cases). Tumors originated from bone or vascular structures, pseudo-tumors, and intraorbital epidermic cysts were also diagnosed, among others. Of a sum of 2,639 tumors diagnosed at this Laboratory in the time period of 5 years (1976 to 1980), there were 22 cases of orbital tumors, reaching a total of 0.8% of all cases. The anatomicopathological study of these processes is somehow important to diagnose and to establish an adequate therapy. The incidence of the expansive processes involving the orbit allows an epidemiological characterization of the different medical services responsible for the treatment of eye diseases. Despite its lower frequencies when compared to the diagnosis from other branches of Anatomical Pathology, Eye pathology has developed considerably over the past few years, contributing to more accurate diagnosis and to a better understanding of mechanisms responsible for these processes.

Effect of Improved Nasal Airflow After Adenoidectomy on Nasal Erectile Tissue

To determine the effect of improved nasopharyngeal airflow after adenoidectomy on nasal turbinate erectile tissue in pediatric patients. Clinical, prospective, before-and-after study. Pediatric Otolaryngology Clinic at Hospital da Criança Santo Antônio de Porto Alegre (Complexo Hospitalar Santa Casa de Porto Alegre). Twenty-one 5- to 11-year-old children diagnosed as having severe nasal obstruction, with an indication for adenoidectomy. Adenoidectomy. Acoustic rhinometry data before and 90 days after surgery. To specifically monitor erectile tissue behavior, only the volume of the nasal turbinate region was considered (depth, 2.20-5.40 cm). The volume of the turbinate region varied from 6.03 cm(3) in the preoperative evaluation to 6.99 cm(3) in the postoperative evaluation, representing an increase of 16% (P < .04). Multiple linear and logistic regressions did not reveal any factors other than adenoidectomy that could explain this change. Because the only possible explanation for the observed erectile tissue changes was improvement in nasal airflow, we can assume that adenoidectomy favorably affects the behavior of nasal erectile structures and is associated with a decrease in turbinate size. Combined turbinate reduction and adenoidectomy should not be the rule because children may benefit from adenoidectomy alone.

Medida da distância reflexo margem por meio de processamento computadorizado de imagens em usuários de lentes de contato rígidas

To measure the MRD (margin reflex distance) in rigid contact lens wearers and controls by a new method, based on computerized image processing. The patients were selected from the Contact Lens Sector of the Ophthalmology Service at the "Complexo Hospitalar Santa Casa de Porto Alegre", and they were divided into two groups: the first was formed of rigid contact lens wearers (63 eyes) and the second of patients without previous history of contact lens wear (30 eyes). All patients were photographed with a digital camera (Nikon Coolpix 4300). The margin reflex distance was measured by a computerized image processing using the Image J program. The study excluded patients that underwent any kind of intraocular or eyelid surgery, patients with congenital ptosis and patients with giant papillae conjunctivitis. The method utilized to measure margin reflex distance seems simple and more accurate. The average value of the margin reflex distance in the case group was 2.46 mm and in the control group 2.72 mm. The study shows that there is a tendency of decreasing the margin reflex distance with contact lens wear although the data were not statistically significant (p=0.22). The margin reflex distance values show a greater variability in the case group (41.46%) than in the control group (28.96%), that is more homogeneous. This study introduced a new method to measure the margin reflex distance using computerized image processing. This method is accessible and could help in follow-up of the margin reflex distance in contact lens wearers, specially those rigid.

Blefaroptose em usuários de lentes de contato

To investigate the occurrence of acquired blepharoptosis in contact lens wearers. Prospective analysis of 50 contact lens wearers being followed at the Contact Lenses Section of the Ophthalmology Service at the "Complexo Hospitalar Santa Casa de Porto Alegre" between April and November 2004. The margin reflex distance (MRD) was evaluated for the 99 eyelids of contact lens wearers and for the 52 eyelids of controls. A patient whose measurement was less than 2 mm or with an assymetry of margin reflex distance greater or equal to 2 mm were considered with blepharoptosis. The contact lens type and duration of contact lenses wear were evaluated. Five patients presented ptosis, all of them were hard contact lens wearers, one had bilateral and four had unilateral ptosis. The study shows that the contact lens wearers had the margin reflex distance 0.88 mm smaller than the non-wearers. The margin reflex distance values decreased progressively in the studied groups: controls, gelatinous contact lens wearers and rigid contact lens wearers. The study suggests that contact lens wearers have alterations in the margin reflex distance values, especially the rigid contact lens wearers.

Complicações intracranianas das otites médias crônicas supurativas em crianças

Apesar de sua significativa diminuição após o advento dos antibióticos, as complicações intracranianas das otites médias ainda representam uma situação de risco, uma vez que a taxa de mortalidade permanece alta, chegando a 36%. Entre as formas mais comuns estão meningite, abscesso cerebral, abscesso extradural e tromboflebite do seio lateral. Um alto índice de suspeição é fundamental para seu diagnóstico e manejo precoces. É importante a identificação de casos atípicos que podem estar mascarados pelo uso de antimicrobianos. OBJETIVO: Apresentamos seis casos de complicações intracranianas por otite média em crianças e adolescentes ocorridos no período de dois anos no Serviço de Otorrinolaringologia do Complexo Hospitalar Santa Casa (CHSC). FORMA DE ESTUDO: relato de série.

Intracranial complications of chronic suppurative otitis media in children

In spite of significant decrease after antibiotic advent, intracranial complications of otitis media still represent a challenging situation owing to its high mortality rate (36%). The most common presentations are meningitis, cerebral abscess, extradural abscess and lateral sinus thrombophlebitis. For early management, it is necessary to have a high index of suspicion. It is important to identify non-typical cases because they might be masqueraded by antibiotic use. We present six cases of intracranial complications due to otitis media in children and adolescents at Complexo Hospitalar Santa Casa de Porto Alegre for the past two years. Series review.
