Coping nos Doentes Transplantados

O desenvolvimento teórico dos Mecanismos de Coping (MC) tem como base uma dialéctica relacionada com os seus principais factores determinantes: individuais e situacionais (na base das duas abordagens do coping: disposicional e constitucional). Actualmente a classificação dos MC mais utilizada é baseada em duas dimensões: coping focado na emoção, e coping focado na resolução de problemas. Considera-se essencial que os métodos de classificação dos MC tenham em conta a coexistência de elementos disposicionais estáveis com uma variabilidade situacional dos MC. São abordados alguns instrumentos de medição de coping, baseados em diferentes pressupostos teóricos. O coping pode influenciar a saúde através de vários mecanismos (sistema neuroendócrino, comportamentos relacionados com os riscos para a saúde e adesão terapêutica) e é incluído em dois dos principais modelos teóricos de saúde (Moos & Schaefer e modelo de Leventhal). Com base numa revisão da literatura, concluiu-se que os estilos de coping mais prevalentes no pré transplante foram: aceitação, coping activo, e procura de suporte, sendo os menos utilizados: auto culpabilização e evitação. No pós transplante o coping activo e procura de suporte continuam a ser os estilos de coping preferenciais, a par da confrontação, autoconfiança, recurso à religião e coping focado no problema. Os estilos de coping (Evasivo, Emotivo, Fatalistico) estão associados a uma menor capacidade de controlo pessoal sobre a doença, a confrontação a uma maior qualidade de vida, o evitamento à redução da qualidade de vida e ao aumento dos níveis de depressão e a negação ao aumento da não adesão. A compreensibilidade, a sensação de controlo sobre a doença, os estilos de coping «relacionados com a expressão dos afectos» e a negação variam ao longo da evolução do doente transplantado.

Slipped Capital Femoral Epiphysis. A Report of 4 Cases Occurring in One Family

We describe slipped capital femoral epiphysis in 4 members of a black, obese family, who were all first-degree relatives. The aetiology of slipped capital femoral epiphysis is unknown, although it is thought to be multifactorial. Genetic predisposition and environmental factors have been associated with the condition. A familial incidence with at least two cases in the same family has been reported. In epidemiological studies, this incidence ranges from 3% to 35%. Our cases were investigated in an attempt to find a possible aetiological genetic factor. A genetic predisposition with an autosomal dominant pattern of transmission is suggested, although environmental variables must be considered as provocative factors.

Defeitos do Tubo Neural. Experiência de 10 Anos numa Maternidade Central

OBJECTIVES: 1) To determine trends in prevalence of neural tube defects and the impact of therapeutic abortion. 2) To review perinatal management of spina bifida. DESIGN: All spontaneous and therapeutic abortions, still births and live births affected by neural tube defects registered in Alfredo da Costa Maternity in Lisbon, from 1983 to 1992, were retrospectively analysed. RESULTS: Eighty-two cases with neural tube defects are reported and myelomeningocele and anencephaly++ were the most frequent ones. Total prevalence for all defects was 0.78:1000 births with a small upward trend during the last two years. Birth prevalence was 0.6:1000, with a clear downward trend, due to therapeutic abortion. Prenatal diagnosis improved significantly, from 9% of all defects detected in 1983-87 to 77.5% in 1988-92. Since 1989, all cases of anencephaly were detected before birth. Most cases of spina bifida were vaginally delivered, and elective cesarean section occurred in 4. Early closure of the defect was undertaken in 87.6% of the newborns with open spina bifida. CONCLUSION: While total prevalence of neural tube defects remained stable, with only a small upward trend, prenatal diagnosis and therapeutic abortion resulted in a 56.3% fall in birth prevalence. Optimal management of open spina bifida demands a multidisciplinary team with an individual program for each case.

Rastreio Neonatal de Hemoglobinopatias numa População Residente em Portugal

The primary objective of newborn screening of hemoglobinopathies is the early identification of infants with sickle cell disease, as they are at increased clinical risk. Other goals include the identification of other types of clinically significant hemoglobinopathies and the detection of heterozygous carriers followed by the screening and counselling of family members. We performed a pilot study for the neonatal screening of hemoglobinopathies in 400 samples of cord blood taken from a maternity in Lisbon. We did not find any newborn with sickle cell disease. Six samples were from sickle cell heterozygotes, the respective families were studied and informed. We looked for the presence of alpha-thalassemia at birth in 100 consecutive samples of cord blood, by the presence of Hb Bart's, abnormal red blood cell indices and alpha-globin genotype. The results show an incidence of 10% of alpha-thalassemia (-alpha) carriers and 4% of triple alpha-globin gene carriers. The authors discuss the feasibility of neonatal screening of hemoglobinopathies in a Portuguese-speaking population consisting of a low prevalence of Hb S trait autoclonous group and a high prevalence immigrant minority

The simultaneous presence of infectious organisms within cutaneous lesions of Kaposi sarcoma in persons with AIDS has been demonstrated. We describe a patient with concurrent leprosy and Kaposi sarcoma presenting as an immune reconstitution inflammatory syndrome in the setting of AIDS.

Digit Ratio (2D:4D) in Newborns: Influences of Prenatal Testosterone and Maternal Environment

Introduction: The 2D:4D digit ratio is sexually-dimorphic, probably due to testosterone action through the perinatal period. We characterize the 2D:4D ratio in newborn (NB) infants, in between the pre- and postnatal surges of testosterone, and relate it to the mother's 2D:4D and to testosterone levels in the amniotic fluid (AF). Subjects and methods: Testosterone was assayed in samples of maternal plasma and AF collected at amniocentesis. Shortly after birth, 106 NBs and their mothers were measured for 2D:4D ratio. Results: NB males had lower mean 2D:4D ratios than females but this dimorphism was significant only for the left hand (males: 0.927; females: 0.950; p=0.004). Mothers who had sons had lower 2D:4D ratios than those who had daughters and the mother's 2D:4D were higher than those of NBs regardless of sex. Both hands of NB females were negatively correlated with AF testosterone and positively correlated with the mother's 2D:4D, but males showed no significant associations. Maternal plasma testosterone also showed a negative weak correlation with NB's digit ratio in both sexes. Conclusions: Sexual dimorphism at birth was only significant for the left hand, in contrast with reports of greater right hand dimorphism, suggesting that postnatal testosterone is determinant for 2D:4D stabilization. The lower 2D:4D ratios in mothers who had sons support claims that hormone levels in parents are influential for determining their children's sex. NB female's digit ratio, but not males', was associated to the level of AF testosterone. The mother's 2D:4D ratios were positively correlated with their daughters' 2D:4D, but the same was not observed for male NBs, suggesting that prenatal testosterone levels in male fetus lead their 2D:4D ratios to stray from their mothers' with high individual variability.

Deficiência Mental: Casuística da Unidade de Desenvolvimento do Hospital de Dona Estefânia

Segundo a DSM IV a Deficiência Mental (DM) define-se como o funcionamento intelectual global inferior à média (QI < 70) associado a perturbações do comportamento adaptativo com início antes dos 18 anos. Procurou-se caracterizar retrospectivamente a população de crianças com DM observadas no Centro de Desenvolvimento do Hospital de Dona Estefânia (CDHDE), entre Janeiro 2005 e Junho 2007. Foram avaliados os dados epidemiológicos, gravidade, etiologia, co-morbilidade e intervenção proposta. Do total de 232 processos clínicos observados, 185 apresentavam DM. Classificaram-se em DM ligeira 112 (61%), DM moderada 54 (29%), DM grave 17 (9%) e profunda 2 (1%). Foram definidas etiologias em 86 crianças (46%) sendo a taxa de diagnóstico mais elevada na DM de maior gravidade. Observou-se uma elevada variabilidade de etiologias: as mais frequentemente encontradas foram as doenças genéticas, prematuridade e patologia associada. Foi detectada co-morbilidade em 123 crianças (66%), sendo a mais frequente as do foro oftalmológico (57 crianças, 46%). Foram propostas e sinalizadas para apoio a totalidade das crianças com DM, 47% em intervenção precoce e 58% em educação especial, das quais 5% usufruiram, por curto período, do apoio simultaneo de educadora de Intervenção Precoce e de docente do Ensino Especial, durante o período inicial de integração em jardim de infância. Observou-se um predomínio do sexo masculino. Foi efectuada caracterização clínica e funcional das crianças seguidas no CDHDE com o diagnóstico de DM e encontraram-se semelhanças entre os dados presentes e os descritos na literatura. Contudo alguns dados diferem de outras casuísticas decorrente, muito provavelmente decorrente da heterogeneidade da população estudada, quer do ponto de vista etiológico, quer no referente aos grupos etários, provavelmente condicionada, pela política assistencial.

Classificação Internacional de Funcionalidade (CIF): Conceitos, Preconceitos e Paradigmas. Contributo de um Construto para o Percurso Real em Meio Natural de Vida.

A autora aborda o historial, génese e objectivos da Classificação Internacional de Funcionalidade para crianças e jovens, implementada pela Organização Mundial de Saúdeem 2007. Sublinha o papel de complementaridadade da CIF relativamente a outras classificações como a Classificação Internacional de Doenças (CID), em que a primeira visa caracterizar as capacidades e dificuldades de crianças e jovens com deficiência, ou seja, caracterizar do ponto de vista funcional cada criança e jovem, independentemente do diagnóstico etiológico médico. Trata-se da mudança de paradigma bio-médico para a do indivíduo que apresenta determinadas competências e dificuldades, em que estas últimas são definidas em função do ambiente – facilitador ou actuando como barreira. Assim, é dado enfoque ao ambiente para que este seja modificado transformando os factores que actuam como barreira em facilitadores, que anulem ou atenuem as dificuldades. Sendo a deficiência e ou doença uma experiência universal, a CIF vem colmatar uma importante lacuna na dificuldade de comunicação e articulação entre os diversos actores intervenientes no apoio socio educativo e médico destas crianças,criando uma linguagem acessível aos técnicos envolvidos – educadores, terapeutas e outros profissionais ligados à infância, por força envolvidos, dando uma maior ênfase à interacção criança/meio numa perspectiva holística de bem estar bio-psico-social.

Lúpus Eritematoso Sistémico

O Lúpus Eritematoso Sistémico (LES) é uma doença multissistémica, auto-imune, caracterizada por inflamação vascular e do tecido conjuntivo, com anticorpos antinucleares. As manifestações clínicas são variáveis, com uma história natural progressiva e imprevisível. Apresentamos o caso de uma adolescente, com antecedentes de artrite dos joelhos, febre e astenia de etiologia não esclarecida, com um ano de evolução. Internada na Unidade de Cuidados Intensivos Pediátricos por pneumonia bilateral a Streptococcus pneumoniae complicada com derrame pleural, anasarca e hematúria macroscópica. Iniciou antibioticoterapia, com evolução favorável, após o que se verifica agravamento clínico, com reaparecimento do derrame pleural, lesões vesiculares disseminadas sugestivas de etiologia herpética, hipertensão arterial sintomática e convulsão tónico-clónica generalizada. Da investigação, destaca-se estudo imunológico compatível com LES em actividade, poliserosite, proteinúria nefrótica, nefrite lúpica classe IV e anemia grave.

Specificity and Sensitivity of Screening for Anti-HLA Antibodies in Kidney Allograft Dysfunction

BACKGROUND: Prospective testing for posttransplant circulating anti-HLA antibodies seems to be a critical noninvasive tool, but confirmatory data are lacking. MATERIALS AND METHODS: Over the last 3 years, peritubular capillary (PTC) C4d deposition was prospectively sought by an immunofluorescence technique applied to frozen tissue in biopsies obtained for allograft dysfunction. Screening for circulating anti-HLA class I/II alloantibodies (AlloAb) by the flow cytometric test was performed simultaneously. RESULTS: We evaluated 132 sets of biopsies and simultaneous serum samples. PTC C4d deposition was demonstrated in 15.9% (21/132) of biopsies. Circulating anti-HLA I/II AlloAb were detected in 25% (33/132) of serum samples. Employing receiver-operator characteristic (ROC) curves for all C4d-positive biopsies, screening for AlloAb showed a global specificity of 82% and sensitivity of 61.9%. When this analysis was restricted to biopsies obtained in the first month posttransplantation, the sensitivity increased to 81.8%, but the specificity decreased to 76.9%. After the first month posttransplantation, we observed sensitivity of 40.0% and a specificity of 86.4%. In the first month posttransplantation, all patients with a diagnosis of acute antibody-mediated rejection displayed circulating anti-HLA class I/II, but not always at the same time as the C4d-positive biopsy. CONCLUSIONS: In the first month posttransplantation, prospective monitoring of anti-HLA antibodies may be useful. The high sensitivity allows the identification of patients at risk, affording an earlier diagnosis of antibody-mediated rejection. After the first month, the test can be used to evaluate allograft dysfunction episodes, since positivity is highly suggestive of an antibody-mediated process.

Laparoscopic Assisted Vaginal Hysterectomy Versus Vaginal Hysterectomy

Introduction: Hysterectomy is the commonest gynecologic operation, performed for malignant and benign conditions. There are many approaches to hysterectomy for benign disease. Studies comparing the techniques have showed that vaginal hysterectomy has benefits in terms of reduced hospital stay, faster recovery and less operating time. Objective: The purpose of this study is to compare the surgical and immediate postoperative outcomes of Laparoscopic Assisted Vaginal Hysterectomy (LAVH) with those of Vaginal Hysterectomy (VH). Methods: Retrospective descriptive study, comparing two groups of women who underwent LAVH or VH in our department during a 24 months period, from January 2009 to December 2010. The two groups were compared regarding age, vaginal deliveries, previous abdominal surgery, uterine and adnexal pathology, intra-operative and post-operative complications, uterus weight, blood loss and number of days until discharge. Results: In our study 42 LAVH and 99 VH were included, with a patient mean age of 47 and 59, respectively. The most frequent indication for hysterectomy was fibroids (80%) for LAVH and POP(58.6%) for HV. In LAVH group 47.6% of patients had previous abdominal surgery, vs 28.2% in VH group. The medium operative time was 167 minutes for LAVH vs 99 minutes for HV. The intra-operative complications were one case (2%) of accidental incision of rectum in LAVH, and one bladder incision in the VH (1%). There were 3 conversions to laparotomy for difficult technique (7%) in LAVH group. There were no significant post-operative complications for LAVH. In VH group there were 2 cases of haemoperitoneum (2%) and 1 case requiring blood transfusion (1%). The mean time for discharge was 4.23 days for LAVH and 4.46 days for VH. Conclusions: In our study, the main advantage for VH was the reduced operative time. In terms of time to discharge there was no difference between the 2 groups. The main intra-operative complication of LAVH was the risk of conversion to laparotomy, but post-operatively this procedure had fewer complications than VH. In conclusion, LAVH is a safe option for women requiring hysterectomy in cases where VH is anticipated to be technically difficult.

A Propósito de um Tumor Abdomino-Pélvico na Gravidez. Um Caso Clínico

Durante a gravidez podem ser diagnosticados tumores abdominais ou pélvicos. De entre estes, os mais comuns no grupo etário em idade reprodutiva, são os tumores uterinos e anexiais. A ecografia é o meio mais comum para apoiar o diagnóstico; contudo, o crescimento uterino e a sua relação com os anexos, podem levar por vezes a diagnósticos enganadores. É a propósito de uma dessas situações, rara na gravidez, que se descreve o seguinte caso clínico.

Peritubular Capillaries C4d Deposits in Renal Allograft Biopsies and Anti HLA I/II Alloantibodies Screening. Incidence and Clinical Importance

Aim: To characterise clinically the patients with C4d in peritubular capillaries deposits (C4dPTCD) and/or circulating anti-HLA class I/II alloantibodies. To determine the correlation between positive C4dPTCD and circulating anti-HLA class I/II alloantibodies during episodes of graft dysfunction. Subjects and Methods: C4d staining was performed in biopsies with available frozen tissue obtained between January 2004 and December 2006. The study was prospective from March 2005, when a serum sample was obtained at the time of biopsy to detect circulating anti-HLA class I/II alloantibodies. Results: We studied 109 biopsies in 86 cadaver renal transplant patients. Sixteen of these (14.7%) presented diffuse positive C4dPTCD. There was a 13.5% rate of +C4dPTCD incidence within the first six months of transplantation and 16% after six months (p>0.05). Half of the +C4dPTCD in the first six months was associated with acute humoral rejection. After six months, the majority of +C4dPTCD (n=7/8) was present in biopsies with evidence of interstitial fibrosis/tubular atrophy and/or transplant glomerulopathy. The C4dPTCD was more frequent in patients with positive anti-HCV antibodies(p<0.0001), a previous renal transplant (p=0.007), and with a panel reactivity antibody (PRA) ≥ 50%(p=0.0098). The anti-HCV+ patients had longer time on dialysis (p=0.0019) and higher PRA(p=0.005). Circulating anti-HLA I/II alloantibodies were screened in 46 serum samples. They were positive in 10.9% of samples, all obtained after six months post transplant. Circulating alloantibodies were absent in 92.5% of the C4d negative biopsies. Conclusion: We found an association between the presence of C4dPTCD and 2nd transplant recipients,higher PRA and the presence of anti-HCV antibodies. The presence of HCV antibodies is not a risk factor for C4dPTCD per se, but appears to reflect longer time on dialysis and presensitisation. In renal dysfunction a negative alloantibody screening is associated with a reduced risk of C4dPTCD (<10%).
