Nursing workload in specialized Semi-intensive Therapy unit: workforce size criteria

Abstract OBJECTIVE To assess the nursing workload (NW) in Semi-intensive Therapy Unit, specialized in the care of children with Craniofacial anomalies and associated syndromes; to compare the amount of workforce required according to the Nursing Activities Score (NAS) and the COFEN Resolution 293/04. METHOD Cross-sectional study, whose sample was composed of 72 patients. Nursing workload was assessed through retrospective application of the NAS. RESULTS the NAS mean was 49.5%. Nursing workload for the last day of hospitalization was lower in patients being discharged to home (p<0.001) and higher on the first compared to last day of hospitalization (p< 0.001). The number of professionals required according to NAS was superior to the COFEN Resolution 293/04, being 17 and 14, respectively. CONCLUSION the nursing workload corresponded to approximately 50% of the working time of nursing professional and was influenced by day and outcome of hospitalization. The amount of professionals was greater than that determined by the existing legislation.

Neurodevelopmental risk factors in schizophrenia

The authors review environmental and neurodevelopmental risk factors for schizophrenic disorders, with emphasis on minor physical anomalies, particularly craniofacial anomalies and dermatoglyphic variations. The high prevalence of these anomalies among schizophrenic subjects supports the neurodevelopmental theory of the etiology of schizophrenia, since they suggest either genetically or epigenetically controlled faulty embryonic development of structures of ectodermal origin like brain and skin. This may disturb neurodevelopment that in turn may cause these subjects to be at increased risk for the development of schizophrenia and related disorders. The precise confirmation of this theory, at least in some cases, will provide further understanding of these illnesses, allowing easy and inexpensive identification of subjects at risk and providing guidelines for the development of new pharmacological interventions for early treatment and even for primary prevention of the illness.

Reduced folate carrier 1 (RFC1) is associated with cleft of the lip only

In this report, we have reanalyzed genotyping data in a collection of families from South America based on maternal origin. Genotyping analysis was performed at the Craniofacial Anomalies Research Center at the University of Iowa. These genotypes were derived from genomic DNA samples obtained from blood spots from children born with isolated orofacial clefts in 45 hospitals located in eight countries (Argentina, Bolivia, Brazil, Chile, Ecuador, Paraguay, Uruguay, and Venezuela) collaborating with ECLAMC (Latin American Collaborative Studies of Congenital Malformations) between January 1998 and December 1999. Dried blood samples were sent by regular mail to the Laboratory of Congenital Malformations, Federal University of Rio de Janeiro. Previous findings suggested that mitochondrial haplotype D is more commonly found among cleft cases born in South America. We hypothesized that association of certain genes may depend upon the ethnic origin, as defined by population-specific markers. Therefore, we tested if markers in MTHFR (5,10-methylenetetrahydrofolate reductase) and RFC1 (reduced folate carrier 1) were associated with oral clefts, depending on the maternal origin defined by the mitochondrial haplotype. Transmission distortion of alleles in MTHFR C677T and RFC1 G80A polymorphic variants was tested in 200 mother/affected child pairs taking into consideration maternal origin. RFC1 variation was over-transmitted to children born with cleft lip only (P = 0.017) carrying mitochondrial DNA haplotypes other than haplotype D. Our results provide a new indication that variation in RFC1 may contribute to cleft lip only. Future studies should investigate the association between oral clefts and RFC1 based on more discrete phenotypes.

Influência do padrão respiratório na morfologia craniofacial

OBJETIVO: este estudo teve como objetivo avaliar por meio de análise cefalométrica as diferenças nas proporções faciais de crianças respiradoras bucais e nasais. FORMA DE ESTUDO: coorte transversal. MATERIAL E MÉTODO: Foram selecionadas 60 crianças entre 6 e 10 anos que, após avaliação otorrinolaringológica para o diagnóstico do tipo de respiração, foram divididas em dois grupos: grupo I, constituído de crianças respiradoras bucais, com elevado grau de obstrução das vias aéreas e grupo II, composto de crianças respiradoras nasais. Os pacientes foram submetidos à avaliação ortodôntica por meio de radiografias cefalométricas em norma lateral, a fim de avaliar as proporções faciais, através das seguintes medidas cefalométricas: SN.GoGn, ArGo.GoMe, N-Me, N-ENA, ENA-Me, S-Go, S-Ar, Ar-Go; e os seguintes índices: iAF=S-Go / N-Me, iAFA=ENA-Me / N-Me e iPFA=N-ENA / ENA-Me. RESULTADO: Foi constatada que a inclinação do plano mandibular (SN.GoGn) nos pacientes respiradores bucais foi estatisticamente maior que nos respiradores nasais, enquanto que a proporção da altura facial posterior e anterior (iAF), e da altura facial anterior superior e inferior (iPFA) foram estatisticamente menores nos pacientes bucais, indicando altura facial posterior menor que a anterior e altura facial anterior inferior aumentada nesses pacientes. CONCLUSÃO: Pode-se concluir, então, que os respiradores bucais tendem a apresentar maior inclinação mandibular e padrão de crescimento vertical, evidenciando a influência da função respiratória no desenvolvimento craniofacial.

Dor craniofacial e anormalidades anatômicas das cavidades nasais

A relação entre variações anatômicas nasais e dores craniofaciais é analisada com base em uma revisão da literatura a respeito deste assunto. Os fatores fisiopatológicos que podem estar implicados nesta reação se mostram muito mais amplos do que simples alterações do septo nasal e conchas nasais que possam causar estímulo mecânico, através do contato entre estas estruturas abrangendo fatores infecciosos, inflamação neurogênica, correlação com migrâneas e o papel da obstrução nasal. Os achados clínicos de diversos autores incluindo a utilização do teste com anestésico tópico para comprovação desta relação causal, assim como para indicação de tratamento cirúrgico, além dos bons resultados deste tratamento, são citados. Discute-se o mecanismo de alívio da dor obtido através de correções cirúrgicas do septo e conchas nasais Estes dados nos levam a concluir que há múltiplos fatores etiológicos envolvidos, o que, inevitavelmente, questiona o papel do aspecto mecânico como fundamental.

Noonan syndrome: a clinical and genetic study of 31 patients

Noonan syndrome is a multiple congenital anomaly syndrome, inherited in an autosomal dominant pattern. We studied 31 patients (18 males and 13 females) affected by this disorder regarding their clinical and genetic characteristics. The most frequent clinical findings were short stature (71%); craniofacial dysmorphisms, especially hypertelorism, ptosis, downslanting of the palpebral fissures; short or webbed neck (87%); cardiac anomalies (65%), and fetal pads in fingers and toes (70%). After studying the probands' first-degree relatives, we made the diagnosis of Noonan syndrome in more than one family member in three families. Therefore, the majority of our cases were sporadic.

Hydronephrosis in Schinzel-Giedion syndrome: an important clue for the diagnosis

Schinzel-Giedion syndrome is a rare autosomal recessive disorder characterized by coarse facies, midface retraction, hypertrichosis, multiple skeletal anomalies, and cardiac and renal malformations. Craniofacial abnormalities of this syndrome sometimes resemble a storage or metabolic disease. The pathogenesis of the disease remains unknown. The objective of this report was to emphasize the importance of congenital bilateral hydronephrosis for the diagnosis of Schinzel-Giedion syndrome. We describe the first Brazilian case of a newborn with typical facies, generalized hypertrichosis, cardiac and skeletal anomalies, and bilateral hydronephrosis detected during pregnancy and confirmed later by abdominal ultrasonography. Chromosomal constitution was normal. Of the 35 cases already reported in the literature, 31 presented hydronephrosis, which is considered an important clue in diagnosis. If Schinzel-Giedion syndrome were indexed as a cause of congenital hydronephrosis, its identification would be greatly facilitated, since the majority of the other findings in Schinzel-Giedion syndrome are nonspecific and common to many genetic syndromes.

Multiple arterial anomalies in the newborn infant. Echocardiographic and angiographic diagnosis

Multiple arterial anomalies characterized by tortuosity and rolling of the pulmonary arteries and aorta were diagnosed on echocardiography in an asymptomatic newborn infant with a phenotype suggesting Ehlers-Danlos syndrome. These changes were later confirmed on angiography, which also showed peripheral vascular abnormalities. The electrocardiogram showed a probable hemiblock of the left anterosuperior branch, and the chest x-ray showed an excavated pulmonary trunk with normal pulmonary flow.

Unsupported valvuloplasty in children with congenital mitral valve anomalies. Late clinical results

OBJECTIVE: To analyze late clinical evolution after surgical treatment of children, with reparative and reconstructive techniques without annular support. METHODS: We evaluated 21 patients operated upon between 1975 and 1998. Age 4.67±3.44 years; 47.6% girls; mitral insufficiency 57.1% (12 cases), stenosis 28.6% (6 cases), and double lesion 14.3% (3 cases). The perfusion 43.10±9.50min, and ischemia time were 29.40±10.50min. The average clinical follow-up in mitral insufficiency was 41.52±53.61 months. In the stenosis group (4 patients) was 46.39±32.02 months, and in the double lesion group (3 patients), 39.41±37.5 months. The echocardiographic follow-up was in mitral insufficiency 37.17±39.51 months, stenosis 42.61±30.59 months, and in the double lesion 39.41±37.51 months. RESULTS: Operative mortality was 9.5% (2 cases). No late deaths occurred. In the group with mitral insufficiency, 10 (83.3%) patients were asymptomatic (p=0.04). The majorit y with mild reflux (p=0.002). In the follow-up of the stenosis group, all were in functional class I (NYHA); and the mean transvalve gradient varied between 8 and 12mmHg, average of 10.7mmHg. In the double lesion group, 1 patient was reoperated at 43 months. No endocarditis or thromboembolism were reported. CONCLUSION: Mitral stenosis repair has worse late results, related to the valve abnormalities and associated lesions. The correction of mitral insufficiency without annular support showed good long-term results.

Corrected transposition of the great arteries with several associated anomalies in a 68-year-old patient

Few patients with corrected transposition of the great arteries survive past 50 years of age because of the association with congenital defects, development of total atrioventricular block, and right ventricular dysfunction. We report the case of a male patient with dextrocardia in situs solitus and corrected transposition of the great arteries associated with a wide atrial septal defect and severe pulmonary valvar and subvalvar stenoses. The patient also developed a large aneurysm on the pulmonary artery, total atrioventricular block diagnosed 8 years earlier, symptoms of dysfunction of the systemic ventricle in the previous 2 years, insufficiency of the left atrioventricular valve, and aortic regurgitation. Despite all these associated anomalies, the patient developed class III cardiac decompensation only at the age of 68 years, which makes this case a rarity. The patient was clinically treated, and was discharged from the hospital in good condition.

Características tomográficas da displasia fibrosa craniofacial: estudo retrospectivo de 14 casos

OBJETIVO: Apresentar as várias formas de displasia fibrosa craniofacial em um estudo revisional com 14 exames de tomografia computadorizada. MATERIAIS E MÉTODOS: Foram selecionados 14 casos de displasia fibrosa craniofacial atendidos no Serviço de Cirurgia de Cabeça e Pescoço e Otorrinolaringologia e no Serviço de Diagnóstico por Imagem do Hospital Heliópolis, São Paulo, SP, entre 1991 e 2002. Foram avaliados, pelos autores, três dos achados tomográficos mais relevantes: o número de ossos acometidos, a apresentação radiológica predominante e a uni/bilateralidade da doença no crânio. RESULTADOS: Observou-se predomínio do padrão misto em relação à forma de apresentação da doença. Foram vistos, ainda, acometimento contíguo de dois ou mais ossos e equivalência entre casos de acometimento craniofacial unilateral e bilateral, possivelmente por conta dos pacientes serem, em sua maioria, portadores de displasia fibrosa do tipo monostótica. CONCLUSÃO: O conhecimento das características tomográficas da displasia fibrosa craniofacial é de grande importância para que seja feito planejamento cirúrgico adequado e seguimento pós-tratamento.

Congenital inferior vena cava anomalies: a review of findings at multidetector computed tomography and magnetic resonance imaging

Inferior vena cava anomalies are rare, occurring in up to 8.7% of the population, as left renal vein anomalies are considered. The inferior vena cava develops from the sixth to the eighth gestational weeks, originating from three paired embryonic veins, namely the subcardinal, supracardinal and postcardinal veins. This complex ontogenesis of the inferior vena cava, with multiple anastomoses between the pairs of embryonic veins, leads to a number of anatomic variations in the venous return from the abdomen and lower limbs. Some of such variations have significant clinical and surgical implications related to other cardiovascular anomalies and in some cases associated with venous thrombosis of lower limbs, particularly in young adults. The authors reviewed images of ten patients with inferior vena cava anomalies, three of them with deep venous thrombosis. The authors highlight the major findings of inferior vena cava anomalies at multidetector computed tomography and magnetic resonance imaging, correlating them the embryonic development and demonstrating the main alternative pathways for venous drainage. The knowledge on the inferior vena cava anomalies is critical in the assessment of abdominal images to avoid misdiagnosis and to indicate the possibility of associated anomalies, besides clinical and surgical implications.
