Mosaic Trisomy 18 in a Five-Month-Old Infant - Case Report

Individuals with mosaic trisomy 18, only approximately 5% of all trisomy 18 cases, carry both a trisomy 18 and an euploid cell line. Their clinical findings are highly variable, from the absence of dysmorphic features to the complete trisomy 18 syndrome. A five month old daughter of a 38-year-old mother, with vomiting and feeding problems, was referred to our department. She was undernourished and had axial hypotony and developmental delay, an irregular pattern of hypopigmentation on the right side of the abdomen, and moderate sagittal body asymmetry with left-side muscular hemihypotrophy.Mild craniofacial dysmorphy included dolichocephaly, frontal bossing, prominent occiput, long downslanting palpebral fissures, hypertelorism, and retrognathia. A complex heart defect with atrial and ventricular septal defects, pulmonary artery stenosis, and bicuspid aortic valve was identified. Cytogenetic analysis revealedmosaic trisomy 18with trisomy in 90%of peripheral lymphocytes and 17%of skin fibroblasts.This case adds to our knowledge of the phenotypic spectrum and the natural history of mosaic trisomy 18 by adding a dysmorphic feature and a cardiac abnormality that, to the best of our knowledge, had not been previously described.

Gravidez após Colocação de Banda Gástrica para Tratamento da Obesidade Mórbida

Obesity is known to have a negative impact on pregnancy outcome, as it is associated with an increase in the incidence of gestational diabetes, hypertension, preeclampsia, neural tube defects, macrosomia, and late fetal death. Gastric banding is considered an appropriate intervention for morbid obesity when other weight-loss measures are unsuccessful, and this treatment has been shown to be effective in causing a sustainable weight loss. Some women will become pregnant after bariatric surgery, and the nutritional and metabolic challenges brought by gastric banding may have a profound impact on maternal health and pregnancy outcome. The authors report the case of a 27 year old pregnant woman, with a past medical history of gastric banding surgery for morbid obesity. At 18 weeks of gestation, the patient started complaining of severe nausea and vomiting, The situation deteriorated three weeks later when she rapidly developed severe desnutrition, dehydration and early signs of liver and renal failure. Migration of the gastric band was diagnosed, and laparoscopy conducted to remove it. In the day following surgery the patient complained of absent fetal movements, and an intrauterine demise was diagnosed on ultrasound. Pathological examination of the fetus and placenta failed to reveal the cause of death, but no growth restriction was documented, suggesting the occurrence of an acute event.

SEPTIC SHOCK IN PATIENT WITH DISSEMINATED HISTOPLASMOSIS ASSOCIATED WITH AIDS: A CASE REPORT

SUMMARY Histoplasmosis is a systemic mycosis caused by Histoplasma capsulatum, which may present itself as a serious infection in immunocompromised individuals. We present a case of 31-year-old female with newly diagnosed HIV infection and history of fever, general and respiratory symptoms and diffuse hyperchromic papules through the body. She was admitted, with rapid progression to septic shock, and the presence of neutrophils filled with yeast-like organisms was detected on peripheral blood smear hematoscopia on the third day of hospitalization. The following is a brief review on the clinical picture and management of histoplasmosis.

Zinc Therapy of Neurological Wilson's Disease in a Woman with Two Foetus with Agenesis of the Corpus Callosum

8A>C>86A G:EDGI: A patient diagnosed Wilson’s disease (WD) 22 years previously, successfully treated initially with zinc, developed neuropsychiatric disease after years of irregular therapy. Reassuming zinc therapy was successful. After a normal pregnancy, she had two therapeutic abortions for corpus callosum agenesis, and a missed abortion. We review the genetics, physiopathology, clinics and imagiologic response to zinc therapy, the problems of pregnancy in WD, advising to maintain therapy. A hypothetic cause for fetus brain anomaly would be hypocupremia due to zinc therapy, confronting with two other possibilities, one related to Wilson’s disease in itself, other due to a congenital syndrome of agenesis of the corpus callosum, impossible to diagnose by our available diagnostic methods.

Vulvar Lichen Sclerosus: Efficacy of Photodynamic Therapy Under Conscious Sedation with Inhaled 50% Nitrous Oxide and Oxygen Mixture

Anogenital lichen sclerosus is a chronic, inflammatory, mucocutaneous disorder of significant morbidity. Common symptoms include pruritus, pain, dysuria, and dyspareunia, frequently of difficult control. Photodynamic therapy (PDT) may be an effective therapeutic option in selected cases refractory to first--‐line treatment options. However, procedure--‐related pain is a limiting factor in patient adherence to treatment. Conscious sedation and analgesia with a ready--‐to--‐use gas mixture of nitrous oxide and oxygen is useful in short--‐term procedures. It provides a rapid, effective, and short--‐lived effect, without the need for anesthesiology support. A 75--‐year--‐old woman presented with a highly symptomatic, histologically confirmed vulvar lichen sclerosus, with at least 15 years of evolution. Pain, pruritus, and dysuria were intense and disabling. Treatment with ultrapotent topical corticosteroids proved to be ineffective despite patient compliance. She was then referred for PDT. A total of 3 sessions were performed, held at a mean interval of 9 weeks, and under the analgesic and sedative effect of nitrous oxide/oxygen gas. Response to treatment was evaluated through a daily, self--‐reported pain rating scale. Dysuria remitted completely after the first PDT session. An 80% reduction in pruritus and pain was observed after the third session, and has been sustained for the past six months without further need for topical corticotherapy. Treatment sessions were well tolerated and pain-- free, with no side effects to report. PDT appears to be effective in the symptomatic treatment of vulvar lichen sclerosus. To the authors’ knowledge this is the first case reporting the use of inhaled nitrous oxide/oxygen gas mixture during PDT performed in the genital area. Its analgesic and sedative effects may increase patients’ adherence to this painful procedure. Furthermore, given its safety, it can be easily managed in outpatient clinics by trained dermatologists.

Recalcitrant Leg Ulcers as the Only Manifestation of Essential Type 2 Cryoglobulinemia

Chronic leg ulcers are persistent conditions that might be a diagnostic and therapeutic challenge, with great impact in health care costs and patients’ quality of life. We report a case of a 60-year-old woman, with long-lasting recalcitrant leg ulcers, which led to left leg amputation 10 years ago. Several attempts to heal the right leg were made, including skin grafting in three different occasions and several surgical debridements, all with unsatisfactory outcome. Some months before the ulcers began, the patient had been diagnosed with undifferentiated connective tissue disease because of arthralgia and positive antinuclear antibodies, therefore low dose systemic corticosteroids and azathioprine were prescribed. For the last 4 years she has been followed in our department and since then no evidence of clinical or laboratorial criteria for autoimmune diseases was found, thus the immunosuppressive therapy was stopped. She maintained ever since a high rheumatoid factor but without other evidence of autoimmune disease. Medical history was otherwise irrelevant. Several cutaneous biopsies were performed, with no evidence of malignancy or vasculitis. Recently, cryoglobulins became positive, with type 2b cryoglobulin identification on immunofluorescence. Serology for Hepatitis C virus was consistently negative, hence an Essential type 2 Cryoglobulinemia diagnosis was established. No renal impairment, vascular purpura, arthralgia or arthritis was found. The authors emphasize the importance of considering less common etiologies for chronic leg wounds, even in the absence of other suggestive symptomatology, as well as the pertinence of reconsidering diagnosis in highly suspect cases.

Metástases temporais: a propósito de um caso clínico

A metastização óssea para a cabeça e pescoço é rara. Em 20-35% dos casos, pode ser a primeira manifestação de uma neoplasia oculta. No caso específico do osso temporal, as metástases são originárias, mais frequentemente, da mama, pulmão, rim, próstata e estômago. Apresenta-se o caso clínico de uma doente, do sexo feminino, 71 anos, com Diagnóstico de Carcinoma Ductal tipo Cribiforme na mama esquerda, tendo sido submetida a mastectomia total, quimioterapia e radioterapia. À observação apresentava um quadro clínico de otalgia esquerda, associada a paralisia facial da hemiface ipsilateral, sem outros sintomas otológicos. Foi-lhe diagnosticada Otite Média Crónica agudizada, tendo sido medicada e pedida Tomografia Computorizada ao Ouvido Esquerdo, que demonstrou exuberante espessamento dos tecidos moles epicranianos temporo-parieto-occipitais à esquerda com extensão ao canal auditivo externo do mesmo lado. Por agravamento da sintomatologia, foi internada no Serviço de Otorrinolaringologia deste hospital para administração de terapêutica endovenosa, tendo-se admitido a hipótese diagnóstica de Otite Externa Maligna. Por manutenção do quadro, apesar de terapêutica optimizada, foi submetida a intervenção cirúrgica onde foi efectuada biopsia temporal, tendo sido diagnosticado lesão metastática por carcinoma invasivo da mama.

Mucopiocelo fronto-etmoidal, a propósito de um caso clínico

O mucocelo é uma lesão quística, benigna, expansiva dos seios perinasais. A sobreinfecção deste, designada de mucopiocelo, pode levar a um período de crescimento rápido, com maior risco de complicações. Relata-se o caso clínico de uma doente do sexo feminino, 59 anos, que recorreu ao Serviço de Urgência após crise inaugural de convulsão tónico-clónica generalizada, com queixas de aumento de volume periorbitário direito e febre desde há 1 semana. Apresentava à direita celulite orbitária e proptose ínfero-externa, com área de flutuação na parte medial da pálpebra superior, oftalmoplegia e quemose do olho direito acompanhada de rinorreia mucopurulenta. Realizou TC que demonstrou volumoso abcesso subperiosteal direito, ao nível da parede medial da órbita, tendo como ponto de partida aparente as células etmoidais anteriores homolaterais e seio frontal direito. Colocou-se a hipótese de mucopiocelo fronto-etmoidal. Foi submetida a drenagem de urgência do abcesso e a cirurgia endoscópica nasal com marsupialização da lesão fronto-etmoidal. Verificou-se resolução completa do quadro clínico. Apesar de consideradas lesões benignas, os mucocelos, apresentam potencial destrutivo, principalmente se infectados, necessitando, por vezes, de intervenção cirúrgica de urgência. A abordagem endoscópica destas lesões reafirma-se como tratamento de eleição.

USE OF LOPINAVIR/RITONAVIR ASSOCIATED WITH ERGOTAMINE RESULTING IN FOOT AMPUTATION: BRIEF COMMUNICATION

A 32-year-old female, was diagnosed in 2004 with a C1 HIV1 infection, using zidovudine/lamivudine 300/150 mg BID and lopinavir/ritonavir 400/100 mg BID, in addition to prophylaxis with trimethoprim-sulfamethoxazole 800/160 mg QD, but no prophylaxis with macrolide antibiotics. The patient presented with a severe headache and was prescribed two capsules of the anti-migraine drug Ormigrein™, which contained ergotamine tartrate 1 mg, caffeine 100 mg, paracetamol 220 mg, hyoscyamine sulfate 87.5 mcg, and atropine sulfate 12.5 mcg. Afterwards she was prescribed one capsule of Ormigrein every 30 minutes for a total of six capsules a day. The patient took the medication as prescribed but developed a pain in her left ankle three days later, which evolved to the need for amputation.

FATAL OUTCOME OF INFECTION BY DENGUE 4 IN A PATIENT WITH THROMBOCYTOPENIC PURPURA AS A COMORBID CONDITION IN BRAZIL

Dengue is currently a major public-health problem. Dengue virus (DENV) is classified into four distinct serotypes, DENV 1-4. After 28 years of absence, DENV-4 was again detected in Brazil in 2010 in Roraima State, and one year later, the virus was identified in the northern Brazilian states of Amazonas and Pará, followed by Rio de Janeiro and São Paulo. In Minas Gerais, the first confirmed case of DENV-4 occurred in the municipality of Frutal in 2011 and has now been isolated from a growing number of patients. Although DENV-2 is associated with the highest risk of severe forms of the disease and death due to the infection, DENV-4 has also been associated with severe forms of the disease and an increasing risk of hemorrhagic manifestations. Herein, the first fatal case of confirmed DENV-4 in Brazil is reported. The patient was an 11-year-old girl from the municipality of Montes Claros in northern Minas Gerais State, Brazil. She had idiopathic thrombocytopenic purpura as a comorbid condition and presented with a fulminant course of infection, leading to death due to hemorrhagic complications. Diagnosis was confirmed by detection of Dengue-specific antibodies using IgM capture enzyme-linked immunosorbent assay and semi-nested RT-PCR. Primary care physicians and other health-care providers should bear in mind that DENV-4 can also result in severe forms of the disease and lead to hemorrhagic complications and death, mainly when dengue infection is associated with coexisting conditions.

Anti-Tumor Necrosis Factor Alpha-Induced Drug Eruptions: One Patient, More Than a Pattern

Background: Tumor necrosis factor alpha (TNFα) antagonists are effective in treating several immune-inflammatory diseases, including psoriasis and inflammatory bowel disease. The paradoxical and unpredictable induction of psoriasis and psoriasiform skin lesions is a recognized adverse event, although of unclear aetiology. However, histological analysis of these eruptions remains insufficient, yet suggesting that some might constitute a new pattern of adverse drug reaction, rather than true psoriasis. Case report: The authors report the case of a 43-year-old woman with severe recalcitrant Crohn disease who started treatment with infliximab. There was also a personal history of mild plaque psoriasis without clinical expression for the past eight years. She developed a heterogeneous cutaneous eruption of psoriasiform morphology with pustules and crusts after the third infliximab infusion. The histopathological diagnosis was of a Sweet-like dermatosis. The patient was successfully treated with cyclosporine in association with both topical corticosteroid and vitamin D3 analogue. Three weeks after switching to adalimumab a new psoriasiform eruption was observed, histologically compatible with a psoriasiform drug eruption. Despite this, and considering the beneficial effect on the inflammatory bowel disease, it was decided to maintain treatment with adalimumab and to treat through with topicals, with progressive control of skin disease. Discussion: Not much is known about the pathogenesis of psoriasiform eruptions induced by biological therapies, but genetic predisposition and Koebner phenomenon may contribute to it. Histopathology can add new facets to the comprehension of psoriasiform reactions. In fact, histopathologic patterns of such skin lesions appear to be varied, in a clear asymmetry with clinical findings. Conclusion: The sequential identification in the same patient of two clinical and histopathologic patterns of drug reaction to TNFα antagonists is rare. Additionally, to the authors’ knowledge, there is only one other description in literature of a TNFα antagonist-induced Sweet-like dermatosis, emphasizing the singularity of this case report.

Breast Cancer Presents With a Paraneoplastic Neurologic Syndrome

BACKGROUND: Paraneoplastic neurologic syndromes (PNS) pose quite an uncommon neurological complication, affecting less than 1% of patients with breast cancer. Nearly one third of these patients lack detectable onconeural antibodies (ONAs), and improvement in neurologic deficits with concomitant cancer treatments is achieved in less than 30% of cases. CASE PRESENTATION: A 42-year-old, premenopausal woman presented with facial paralysis on the central left side accompanied by a left tongue deviation, an upward vertical nystagmus, moderate spastic paraparesis, dystonic posturing of the left foot, lower limb hyperreflexia and bilateral extensor plantar reflex. After ruling out all other potential neurologic causes, PNS was suspected but no ONAs were found. A PET-CT scan detected increased metabolism in the right breast, as well as an ipsilateral thoracic interpectoral adenopathy. Core biopsy confirmed the presence of an infiltrating duct carcinoma. After breast surgery, the neurologic symptoms disappeared. One week later, the patient was readmitted to the hospital with a bilateral fatigable eyelid ptosis, and two weeks later, there was a noticeable improvement in eyelid ptosis, accompanied by a rapid and progressive development of lower spastic paraparesis. She started adjuvant treatment with chemotherapy with marked clinical and neurological improvement, and by the end of radiotherapy, there were no signs of neurologic impairment. CONCLUSION: This case study highlights the importance of a high level of vigilance for the detection of PNS, even when ONAs are not detected, as the rapid identification and treatment of the underlying tumor offers the best chance for a full recovery.

Evolution of the Human Immunodeficiency Virus Type 2 Envelope in the First Years of Infection is Associated with the Dynamics of the Neutralizing Antibody Response

Background: Differently from HIV-1, HIV-2 disease progression usually takes decades without antiretroviral therapy and the majority of HIV-2 infected individuals survive as elite controllers with normal CD4+ T cell counts and low or undetectable plasma viral load. Neutralizing antibodies (Nabs) are thought to play a central role in HIV-2 evolution and pathogenesis. However, the dynamic of the Nab response and resulting HIV-2 escape during acute infection and their impact in HIV-2 evolution and disease progression remain largely unknown. Our objective was to characterize the Nab response and the molecular and phenotypic evolution of HIV-2 in association with Nab escape in the first years of infection in two children infected at birth. Results: CD4+ T cells decreased from about 50% to below 30% in both children in the first five years of infection and the infecting R5 viruses were replaced by X4 viruses within the same period. With antiretroviral therapy, viral load in child 1 decreased to undetectable levels and CD4+ T cells recovered to normal levels, which have been sustained at least until the age of 12. In contrast, viral load increased in child 2 and she progressed to AIDS and death at age 9. Beginning in the first year of life, child 1 raised high titers of antibodies that neutralized primary R5 isolates more effectively than X4 isolates, both autologous and heterologous. Child 2 raised a weak X4-specific Nab response that decreased sharply as disease progressed. Rate of evolution, nucleotide and amino acid diversity, and positive selection, were significantly higher in the envelope of child 1 compared to child 2. Rates of R5-to-X4 tropism switch, of V1 and V3 sequence diversification, and of convergence of V3 to a β-hairpin structure were related with rate of escape from the neutralizing antibodies. Conclusion: Our data suggests that the molecular and phenotypic evolution of the human immunodeficiency virus type 2 envelope are related with the dynamics of the neutralizing antibody response providing further support for a model in which Nabs play an important role in HIV-2 pathogenesis.

Achondroplasia and Down’s Syndrome – Case Report of a Rare Association

The association of achondroplasia and Down’s syndrome is very rare and only five cases have been reported in the literature so far. These two genetic alterations have overlapping features such as short stature, developmental delay or hypotonia that complicate management and follow up. We report the case of a girl that is unique since she was born from a mother with achondroplasia and a healthy father. Achondroplasia was dominantly inherited from the mother but at birth she had features of Down’s syndrome as well, confirmed later by kariotype. We review her evolution regarding physical health, cognitive problems and adaptive behavior during her eight years of life. To our knowledge this is the first report of the combination of both disorders in which the achondroplasia was inherited and not a “de novo” mutation. We address the problems resulting from the additional burden of having two disorders, and how they can be improved, aiming to help others in the future to deal with these cases.

Relatório de estágio em Ensino do 1.º Ciclo do Ensino Básico

Relatório EPE - Relatório de estágio em Educação Pré-Escolar: O presente relatório foi realizado no âmbito da unidade curricular Prática Pedagógica Supervisionada, inserida no Mestrado em Educação Pré-Escolar e Ensino do 1.º Ciclo do Ensino Básico, da Escola Superior de Educação do Porto, durante o ano letivo 2013/2014, atribuindo qualificação profissional no contexto de pré-escolar. Este documento pretende descrever e analisar o percurso formativo desenvolvido pela mestranda ao longo da sua prática pedagógica supervisionada, numa perspetiva reflexiva sobre a construção dos saberes profissionais para a Educação. Este percurso formativo comprometeu uma atitude investigativa, bem como a mobilização de saberes científicos e legais por forma a articular as vertentes de teoria e prática, perspetivando uma construção integrada dos saberes. A prática pedagógica foi sustentada numa perspetiva construtivista, atribuindo um papel ativo à criança na construção das suas aprendizagens. Esta baseou-se num trabalho de equipa cooperativo, o qual se concretiza através do debate e da partilha de ideias, entre os vários intervenientes da ação, como meio para a transformação da realidade educativa. Ao longo da prática foi, ainda, atribuído um papel fundamental à observação do contexto, sendo esta essencial para a compreensão e conhecimento pleno da criança. Em suma, todo o percurso formativo no qual está englobado a prática pedagógica, levou a uma problematização das questões emergentes da prática, desenvolvendo uma atitude indagadora e reflexiva. Apesar da significante contribuição para a aquisição de competências pessoais e profissionais, o percurso formativo deve ser assumido como uma construção contínua, fundamentado num princípio da aprendizagem ao longo da vida.
