Imunidade pré-concecional e infeção congénita por citomegalovírus – Uma armadilha serológica
Get PDFCongenital cytomegalovirus infections are the most prevalent intrauterine infections worldwide and result from maternal primary or non-primary infections. Diagnosis of primary cytomegalovirus infection during pregnancy is considered reliable and mainly relies on maternal serology. However, diagnosis of non-primary cytomegalovirus infection is more questionable. Herein is reported the case of a 34-week-old male newborn with congenital cytomegalovirus infection of a mother with preconceptional immunity. The organism was identified in urine by polymerase chain reaction in the first week of life. Maternal peripartum serology was the same as prior to conception. This case highlights the pitfalls of cytomegalovirus serology interpretation in non-primary infection during pregnancy. Clinicians should be aware of this and consider congenital cytomegalovirus infection, particularly when suggestive signs are present.info:eu-repo/semantics/publishedVersio

Non-Necrotizing Acute Dermo-Hypodermal Infections: Erysipela and Infectious Cellulitis
Get PDFAs dermo-hipodermites bacterianas agudas não necrotizantes são processos infeciosos que incluem a erisipela e a celulite infeciosa, e são geralmente causadas por estreptococos β–hemolíticos do grupo A. Em mais de 80% dos casos situam-se nos membros inferiores e são fatores predisponentes a existência de solução de continuidade na pele, o linfedema crónico e a obesidade. O seu diagnóstico é essencialmente clínico e o quadro típico baseia-se na presença de placa inflamatória associada a febre, linfangite, adenopatia e leucocitose. Os exames bacteriológicos têm baixa sensibilidade ou positividade tardia. Nos casos atípicos é importante o diagnóstico diferencial com a fasceíte necrotizante e a trombose venosa profunda. A flucloxacilina ou a cefradina são os fármacos de primeira linha. A recidiva constitui a complicação mais frequente, sendo fundamental o correto tratamento dos fatores de risco.Non-necrotizing acute dermo-hypodermal infections are infectious processes that include erysipela and infectious cellulitis, and are mainly caused by group A β-haemolytic streptococcus. The lower limbs are affected in more than 80% of cases and the risk factors are disruption of cutaneous barrier, lymphoedema and obesity. Diagnosis is clinical and in a typical setting we observe an acute inflammatory plaque with fever, lymphangitis, adenopathy and leucocytosis. Bacteriology is usually not helpful because of low sensitivity or delayed positivity. In case of atypical presentations, erysipela must be distinguished from necrotizing fasciitis and acute vein thrombosis. Flucloxacillin and cefradine remain the first line of treatment. Recurrence is the main complication, so correct treatment of the risk factors is crucial.info:eu-repo/semantics/publishedVersio
Management of Psoriasis by Family Physicians: Referral Algorithm and Shared Management with Dermatology
Get PDFIntroduction: The implementation of models capable of improving referral quality, limiting the growth of waiting lists in hospitals, and ensuring the best possible treatment and follow-up of the psoriatic patient is of the utmost importance.
Material and methods: A panel of Family Physicians and Dermatologists discussed and created a simple and effective algorithm of referral for patients with psoriasis.
Results: The proposed algorithm starts when the Family Physician suspects of psoriasis. In case of diagnostic doubt, the patient should be referred to Dermatology. In case of a confirmed diagnosis, the Family Physician should assess the patient's severity and responder profile, evaluate comorbidities and assess the presence of psoriatic arthritis. If psoriasis is mild, topical treatments should be initiated, and if there is no clinical improvement or worsening of the disease, the patient should be referred to Dermatology. If psoriasis is moderate to severe, is located in high impact locations, or in pediatric age, the patient should be referred to Dermatology. In order to enable shared management in terms of follow-up and treatment of these patients, it is critical that the Family Physician has the necessary knowledge regarding the systemic treatments used in psoriasis and their side effects.
Discussion and conclusion: Only a shared management of the psoriatic patient can allow for the best treatment and follow-up of these patients, a more rational use of available medical resources, thus giving the patient the best possible quality of life.Introdução: A implementação de modelos capazes de melhorar a referenciação, por forma a garantir a qualidade e precocidade do diagnóstico, o melhor tratamento e seguimento do doente psoriático é fundamental.Material e Métodos: Um painel de médicos de Medicina Geral e Familiar e Dermatologia discutiu e criou um algoritmo de referenciação simples, eficaz e célere de doentes com psoríase.Resultados: O algoritmo proposto inicia-se quando o clínico de Medicina Geral e Familiar suspeita de psoríase. Caso haja dúvidas no diagnóstico, o doente deve ser referenciado para a dermatologia. No caso de um diagnóstico confirmado, compete ao clínico de Medicina Geral e Familiar avaliar a gravidade e perfil de respondedor do doente, rastrear comorbilidades e a possibilidade de artrite psoriática. Se a psoríase for ligeira, deverão ser iniciados tratamentos tópicos, sendo que, se não houver melhoria clínica ou ocorrer agravamento da doença, o doente deverá ser referenciado para a dermatologia. Se a psoríase for considerada moderada a grave, em localizações de elevado impacto, ou em idade pediátrica, o doente deverá ser referenciado para a dermatologia. Para que o seguimento e tratamento destes doentes seja partilhado, é fundamental que o médico de Medicina Geral e Familiar tenha o conhecimento necessário sobre os tratamentos sistémicos que o doente está a fazer e os seus efeitos adversos.Discussão e Conclusão: Apenas uma gestão partilhada do doente psoriático poderá tornar possível o melhor tratamento e seguimento destes doentes, a utilização mais racional dos recursos médicos disponíveis, proporcionando ao doente a melhor qualidade devida possível.info:eu-repo/semantics/publishedVersio
Prevalência de Risco Nutricional à Admissão na Enfermaria de Medicina Interna em Portugal: Estudo Transversal Multicêntrico ANUMEDI
Get PDFIntroduction: Disease-related undernutrition is highly prevalent and requires timely intervention. However, identifying undernutrition often relies on physician judgment. As Internal Medicine wards are the backbone of the hospital setting, insight into the prevalence of nutritional risk in this population is essential. We aimed to determine the prevalence of nutritional risk in Internal Medicine wards, to identify its correlates, and to assess the agreement between the physicians' impression of nutritional risk and evaluation by Nutritional Risk Screening 2002.
Material and methods: A cross-sectional multicentre study was performed in Internal Medicine wards of 24 Portuguese hospitals during 2017. Data on demographics, previous hospital admissions, primary diagnosis, and Charlson comorbidity index score were collected. Nutritional risk at admission was assessed using Nutritional Risk Screening 2002. Agreement between physicians' impression of nutritional risk and Nutritional Risk Screening 2002 was tested by Cohen's kappa.
Results: The study included 729 participants (mean age 74 ± 14.6 years, 51% male). The main reason for admission was respiratory disease. Mean Charlson comorbidity index score was 5.8 ± 2.8. Prevalence of nutritional risk was 51%. Nutritional risk was associated with admission during the previous year (odds ratio = 1.65, 95% confidence interval: 1.22 - 2.24), solid tumour with metastasis (odds ratio = 4.73, 95% confidence interval: 2.06 - 10.87), any tumour without metastasis (odds ratio = 2.04, 95% confidence interval:1.24 - 3.34), kidney disease (odds ratio = 1.83, 95% confidence interval: 1.21 - 2.75), peptic ulcer (odds ratio = 2.17, 95% confidence interval: 1.10 - 4.25), heart failure (odds ratio = 1.51, 95% confidence interval: 1.11 - 2.04), dementia (odds ratio = 3.02, 95% confidence interval: 1.96 - 4.64), and cerebrovascular disease (odds ratio = 1.62, 95% confidence interval: 1.12 - 2.35). Agreement between physicians' evaluation of nutritional status and Nutritional Risk Screening 2002 was weak (Cohen's kappa = 0.415, p < 0.001).
Discussion: Prevalence of nutritional risk in the Internal Medicine population is very high. Admission during the previous year and multiple comorbidities increase the odds of being at-risk. Subjective physician evaluation is not appropriate for nutritional screening.
Conclusion: The high prevalence of at-risk patients and poor subjective physician evaluation suggest the need to implement mandatory nutritional screening.Introdução: A subnutrição associada à doença apresenta grande morbimortalidade e necessita de intervenção precoce. Contudo, a sua identificação assenta frequentemente no julgamento médico. Adicionalmente, sendo a enfermaria de Medicina Interna o pilar do hospital, é essencial maior conhecimento sobre o estado nutricional desta população. Os objetivos consistiram em determinar a prevalência de risco nutricional na enfermaria de Medicina Interna, identificar fatores relacionados e avaliar a concordância entre a avaliação do risco nutricional baseada no julgamento médico e no Nutritional Risk Screening 2002. Material e Métodos: Estudo transversal multicêntrico realizado nas enfermarias de Medicina Interna de 24 hospitais portugueses durante 2017. Foram avaliadas características demográficas, internamentos prévios, diagnósticos principais, índice de comorbilidades de Charlson e habilitações literárias. O risco nutricional à admissão foi avaliado usando o Nutritional Risk Screening 2002. A concordância entre o julgamento médico e o Nutritional Risk Screening 2002 foi testado usando o teste kappa de Cohen (k). Resultados: Foram incluídos 729 participantes (idade média 74 ± 14,6 anos, 51% do sexo masculino). A principal causa de admissão foi doença respiratória. O índice de comorbilidades de Charlson médio foi 5,8 ± 2,8. A prevalência de risco nutricional foi 51%. O risco nutricional associou-se a internamento recente (odds ratio = 1,65, 95% intervalo de confiança: 1,22 - 2,24), neoplasia sólida metastizada (odds ratio = 4,73, 95% intervalo de confiança: 2,06 - 10,87), neoplasia não metastizada (odds ratio = 2,04, 95% intervalo de confiança: 1,24 - 3,34), doença renal (odds ratio = 1,83, 95% intervalo de confiança: 1,21 - 2,75), úlcera péptica (odds ratio = 2,17, 95% intervalo de confiança: 1,10 - 4,25), insuficiência cardíaca (odds ratio = 1,51, 95% intervalo de confiança: 1,11 - 2,04), demência (odds ratio = 3,02, 95% intervalo de confiança: 1,96 - 4,64) e doença cerebrovascular (odds ratio = 1,62, 95% intervalo de confiança: 1,12 - 2,35). A concordância entre julgamento médico e Nutritional Risk Screening 2002 foi fraca (kappa de Cohen = 0,415, p < 0,001). Discussão: A prevalência de risco nutricional na enfermaria de Medicina Interna é muito elevada. Admissão recente e múltiplas comorbilidades aumentam a probabilidade de risco nutricional. A avaliação subjetiva do médico não é apropriada para o rastreio nutricional. Conclusão: A elevada prevalência de doentes em risco e baixa precisão da avaliação subjetiva médica sugerem a necessidade de implementar rastreio nutricional obrigatório a nível nacional.info:eu-repo/semantics/publishedVersio
Caso clínico imagiológico
Get PDFHirschsprung disease is the most common congenital gut motility disorder and usually diagnosed in the neonatal period. It is caused by an aganglionic bowel segment resulting in absence of intestinal peristalsis and functional obstruction. Diagnosis should be considered in all patients with constipation that does not respond to conventional treatment. Radiography and contrast enema are important diagnostic exams, but the definitive diagnosis is established through histochemical analysis of aganglionic segment biopsy. Treatment is surgical and early recognition is important to avoid complications and improve prognosis.
Herein is reported the clinical case of a young infant presenting to the Pediatric Emergency Department with nausea, vomiting, constipation, refusal to feed, and important abdominal distension. Abdominal radiograph and contrast enema were compatible with Hirschsprung disease. Biopsy histochemical analysis confirmed the diagnosis and surgical treatment was performed.info:eu-repo/semantics/publishedVersio
Perda ponderal como causa de síndrome da artéria mesentérica superior
Get PDFIntroduction and objective: Superior mesenteric artery syndrome (SMAS) is a rare condition in pediatric age, often presenting with non-specific gastrointestinal symptoms. The aim of this report was to highlight the importance of considering/excluding this diagnosis.
Case description: A 17-year-old female presented with slowly progressing epigastralgia, heartburn, early satiety, nausea and sporadic vomiting with one and a half years of evolution. She had lost 13% of her weight in the previous six months. On physical examination, the girl complained of pain on epigastrium palpation, with no further changes. Laboratory tests were normal. Esophageal, gastric and duodenal transit (EGDT) revealed a vertically elongated stomach, with the greater curvature projecting towards the pelvic cavity and a slight delay in gastric emptying. Abdominal computed tomography scan confirmed the diagnosis of SMAS and a conservative approach with a hypercaloric fractionated diet was initiated. The girl maintained multidisciplinary follow-up (Nutrition, Pediatrics and Pedopsychiatry), with marked improvement and without requiring surgical intervention.
Comments: Although rare, SMAS should be considered after exclusion of the most frequent underlying causes of persistent non-specific gastrointestinal symptoms.info:eu-repo/semantics/publishedVersio
Apoio parental e competência parental percecionada − estudo de perceções parentais numa unidade pedopsiquiátrica de primeira infância
Get PDFIntroduction: Perceived parental self-efficacy (PSE) has shown an association with positive parental behavior, highlighting its benefit in promoting child well-being and healthy development. The identification of its potential determinants remains a focus of attention in mental health when assessing parental perceptions and cognitions or planning parental interventions.
Material/Methods: This was a cross-sectional study in an Early Childhood Child Psychiatry Unit. All parents of babies and toddlers assessed for the first time were included and completed a Parenting Sense of Competence (PSOC) scale (portuguese translation, α= 0.75-0.83) and two additional questions concerning perceptions of support from the other parent and family of origin. Average PSOC was compared between both parents and correlations with perceptions of support were tested. Statistical analysis was conducted in SPSS® version 21 through descriptive analysis and variable correlation (t-test and Pearson r).
Results: A total of thirty-four questionnaires were completed. Average PSOC was similar between father and mothers (73.44 vs 72.24, p=0.533). Fathers perceived themselves as more supported than mothers, either from the family of origin (5.09 vs 4.21, p=0.001), as from the other parent (4.91 vs 4.09, p=0.011). A positive correlation was found between father’s PSOC and perception of support from the family of origin (r=0.639, p <0.01).
Conclusions: Among mothers of children followed in this Child Psychiatry Unit, support perceptions did not correlate with perceived parental self-efficacy. However, father’s perceived self-efficacy could relate to perceptions of support, raising clinical attention on how fathers and their family of origin can influence the relational triad. Perceptions of parental support should be explored when considering within-family horizontal relations as a potential mechanism influencing vertical relations through its association with perceived self-efficacy.info:eu-repo/semantics/publishedVersio
Expert consensus recommendations to improve diagnosis of ATTR amyloidosis with polyneuropathy
Get PDFAmyloid transthyretin (ATTR) amyloidosis with polyneuropathy (PN) is a progressive, debilitating, systemic disease wherein transthyretin protein misfolds to form amyloid, which is deposited in the endoneurium. ATTR amyloidosis with PN is the most serious hereditary polyneuropathy of adult onset. It arises from a hereditary mutation in the TTR gene and may involve the heart as well as other organs. It is critical to identify and diagnose the disease earlier because treatments are available to help slow the progression of neuropathy. Early diagnosis is complicated, however, because presentation may vary and family history is not always known. Symptoms may be mistakenly attributed to other diseases such as chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), idiopathic axonal polyneuropathy, lumbar spinal stenosis, and, more rarely, diabetic neuropathy and AL amyloidosis. In endemic countries (e.g., Portugal, Japan, Sweden, Brazil), ATTR amyloidosis with PN should be suspected in any patient who has length-dependent small-fiber PN with autonomic dysfunction and a family history of ATTR amyloidosis, unexplained weight loss, heart rhythm disorders, vitreous opacities, or renal abnormalities. In nonendemic countries, the disease may present as idiopathic rapidly progressive sensory motor axonal neuropathy or atypical CIDP with any of the above symptoms or with bilateral carpal tunnel syndrome, gait disorders, or cardiac hypertrophy. Diagnosis should include DNA testing, biopsy, and amyloid typing. Patients should be followed up every 6-12 months, depending on the severity of the disease and response to therapy. This review outlines detailed recommendations to improve the diagnosis of ATTR amyloidosis with PN.info:eu-repo/semantics/publishedVersio
Complicações orbitárias de sinusite aguda em Pediatria: experiência de oito anos
Get PDFObjectives: Acute sinusitis accounts for up to 82% of orbital infection cases. Infection spreads very quickly, especially through the ethmoid sinus, and orbital complications may arise even under antibiotic therapy. The aim of this study was to describe an 8-year hospital experience with these children.
Methods: All cases of acute sinusitis with orbital complications admitted to the Department of Otorhinolaryngology of Centro Hospitalar e Universitário de Coimbra between 2010 and 2017 were retrospectively reviewed.
Results: Sixty-four patients met the inclusion criteria, with a mean age of 9 ± 4.7 years. Male:female ratio was 1.67:1. Most subjects were admitted in the winter period (57.8%), with 2.9 ± 2.5 days of clinical evolution. The mean Lund Mackay score was 10.6 ± 4.9, with maxillary and ethmoid being the most prevalent involved sinuses (96.4% and 94.6%, respectively), and was inversely correlated with age (p<0.05). Preseptal cellulitis was the most common complication (56.3%). Abscesses were identified in 18.7% of patients, but only four (6.25%) required surgery. Seven cases (10.9%) recurred shortly after hospital discharge and required prolonged antibiotic course. All patients recovered well, without further complications.
Conclusion: Results showed that orbital complications of sinusitis respond well to high doses of endovenous antibiotherapy and patients tend to recover without local comorbidities. Close monitoring of these patients during the first months after hospital discharge is crucial to prevent early relapse.info:eu-repo/semantics/publishedVersio
