CHROMOBLASTOMYCOSIS: A NEGLECTED TROPICAL DISEASE

SUMMARYChromoblastomycosis (CMB) is a chronic fungal infection of the skin and the subcutaneous tissue caused by a transcutaneous traumatic inoculation of a specific group of dematiaceous fungi occurring mainly in tropical and subtropical zones worldwide. If not diagnosed at early stages, patients with CBM require long term therapy with systemic antifungals, sometimes associated with physical methods. Unlike other neglected endemic mycoses, comparative clinical trials have not been performed for this disease. Nowadays, therapy is based on a few open trials and on expert opinion. Itraconazole either as monotherapy or associated with other drugs, or with physical methods, is widely used. Recently, photodynamic therapy has been successfully employed in combination with antifungals in patients presenting with CBM. In the present revision the most used therapeutic options against CBM are reviewed as well as the several factors that may have impact on the patient's outcome.

Association of Intestinal Malrotation and Bochdalek Hernia in an Adult: a Case Report

Background Late presentations of congenital diaphragmatic hernia are rare and differ from the classic neonatal presentation. The association with other congenital malformations in children, mainly intestinal malrotation, is well documented. The diagnosis of this association in adults is very rare, and depends on a high degree of suspicion. Case presentation We report a case of a 50-year-old female Caucasian patient with a previous history of intestinal malrotation diagnosed in adolescence and treated conservatively. She was referred to the hospital with signs and symptoms of intestinal obstruction. The patient undertook computed tomography that confirmed small bowel obstruction with no obvious cause, and a right subphrenic abscess with right empyema was also present. An exploratory laparotomy was performed that revealed an intestinal malrotation associated with a right gangrenous and perforated Bochdalek hernia. Resection of the affected small bowel, closure of the Bochdalek foramen and the Ladd procedure were carried out. Conclusion This case shows a rare association of two rare conditions in adults, and highlights the challenge in reaching the diagnosis and management options.

Phaeohyphomycosis Caused by Alternaria Infectoria Presenting as Multiple Vegetating Lesions in a Renal Transplant Patient

The genus Alternaria is one of the most common black moulds and appears to be increasing as a causative agent of subcutaneous phaeohyphomycosis, particularly among immunosuppressed patients. A 53-year-old patient who had received a kidney transplant presented with multiple verrucous lesions on the distal extremities. Positive histopathology and cultures, in addition to rDNA ITS region sequencing, identified the fungal isolate as Alternaria infectoria. Oral itraconazole was administered for 10 months. A follow-up at 15 months demonstrated no signs of infection. Clinical manifestations of cutaneous alternariosis vary significantly and only a few cases have been described in the literature. Although optimal treatment options remain controversial, this case of phaeohyphomycosis was successfully treated with itraconazole monotherapy.

The Role of Propranolol in the Treatment of Infantile Hemangioma

INTRODUCTION: Infantile hemangioma (IH) is one of the most common childhood tumors. There are various medical or surgical therapeutic options, all with suboptimal results. Recently, the successful use of propranolol for involution of IH was described. We report the results of a single-center experience with this therapeutic option. OBJECTIVE: To prospectively assess the efficacy and safety of propranolol in children with infantile hemangioma. METHODS: We performed a prospective analysis of clinical data of all patients with IH referred to a pediatric cardiology center for baseline cardiovascular assessment prior to propranolol therapy. Propranolol was given at a starting dose of 1 mg/kg/day and titrated to a target dose of 2-3 mg/kg/day according to clinical response. Efficacy was assessed through a photograph-based severity scoring scale. Safety was assessed by collecting data regarding significant side effects. RESULTS: Starting in 2010, 30 patients (15 female) were referred for propranolol treatment of IH, at a median age of six months (1-63 months). The mean target propranolol dose was 2.8 mg/kg/day, with a mean duration of therapy of 12 months. All patients experienced significant reduction of IH size and volume. There were no side effects. CONCLUSIONS: In our experience propranolol appears to be a useful and safe treatment option for severe or complicated IH, achieving a rapid and significant reduction in their size. No adverse effects were observed, although until larger clinical trials are completed, potential adverse events should be borne in mind and consultation with local specialists is recommended prior to initiating treatment.

Tilt Training Increases Vasoconstrictor Reserve in Patients with Neurocardiogenic Syncope

Neurocardiogenic syncope (NCS) is a common clinical entity resulting from an excessive reflex autonomic response, particularly during orthostatism. Treatment options are controversial and of limited effectiveness. Tilt training (TT) is a promising option to treat these patients. However, its mechanism of action and clinical impact remain unclear. OBJECTIVE: To characterize hemodynamic and autonomic responses during a TT program in patients with NCS refractory to conventional measures. METHODS: We studied 28 patients (50% male, mean age 41±14 years) without structural heart disease, with NCS documented by tilt testing. The TT program included 9 tilt sessions (3 times a week, 30 min) (60° - 6 sessions, 70° - 3 sessions), under ECG and blood pressure monitoring combined with home orthostatic self-training and 10° head-up during sleep. Systolic volume, cardiac output, total peripheral resistance, baroreflex sensitivity and heart-rate variability were computed. Patients were reassessed at 1 month and every 6 months for a maximum of 36 months (24±12 months). RESULTS: Over the course of the TT program there was a significant increase in total peripheral resistance (1485±225 vs. 1591±187 dyn·s·cm(-5), p<0.05), with a decrease in standard deviation (206±60 vs. 150±42, p<0.05). During follow-up, syncope recurred in five patients (19%), with a significant reduction in the number of episodes (4.0±3.2/patient in the 12 months before TT vs. 1.4±0.8/patient post-TT, p<0.05). CONCLUSION: In refractory NCS, TT may be an effective therapeutic option, with long-term benefits. These results appear to be due to an increase in vasoconstrictor reserve combined with a reduction in its variance.

Analysis of mental health service financial models with a particular emphasis of Ireland

ABSTRACT: Financing is a critical factor in ensuring the optimal development and delivery of a mental health system. The primary method of financing worldwide is tax-based. However many low income countries depend on out-of-pocket payments. There is a report on Irish Health Care funding but none that deals exclusively with mental health care. This paper analyses the various financial models that exist globally with respect to financing the mental health sector, examines the impact of various models on service users, especially in terms of relative ‘financial burden’ and provides a more detailed examination of the current mental health funding situation in Ireland After extensive internet and hardcopy research on the above topics, the findings were analysed and a number of recommendations were reached. Mental health service should be free at the point of delivery to achieve universal coverage. Government tax-based funding or mandatory social insurance with government top-ups, as required, appears the optimal option, although there is no one funding system applicable everywhere. Out-of-pocket funding can create a crippling financial burden for service users. It is important to employ improved revenue collection systems, eliminate waste, provide equitable resource distribution, ring fence mental health funding and cap the number of visits, where necessary. Political, economic, social and cultural factors play a role in funding decisions and this can be clearly seen in the context of the current economic recession in Ireland. Only 33% of the Irish population has access to free public health care and the number health insurance policy holders has dramatically declined, resulting in increased out-of-pocket payments. This approach risks negatively impacting on the social determinants of health, increasing health inequalities and negatively affecting economic productivity. It is therefore important the Irish government examines other options to provide funding for mental health services.

Contributo para o desenvolvimento de uma metodologia que avalia a posição da omoplata: fidedignidade intra e interobservador e validade concorrente

RESUMO: Introdução: A relação cinemática entre as articulações do CAO apresenta grande importância na função do MS, e é por isso cada vez mais investigada e descrita. O posicionamento da omoplata ganha um importante papel para compreender as DCAO. É indiscutível o importante papel da omoplata na dinâmica do MS, bem como o posicionamento escapular como parâmetro clínico de disfunção do CAO. Todos estes factores criam a necessidade de desenvolver instrumentos de avaliação da posição da articulação ET. A grande maioria dos testes de avaliação, restringem a sua avaliação às disfunções da articulação GU, não integrando uma avaliação mais dinâmica e interactiva que respeite os pressupostos teóricos inerentes ao REU. È importante também que os métodos de avaliação sejam de fácil aplicabilidade clínica e que avaliem fidedignamente e com validade os outcomes. Objectivos: Contribuir para o desenvolvimento de uma metodologia de avaliação da omoplata em diferentes amplitudes do MS, através do estudo da validade concorrente, da fidedignidade intra e inter-observador. Metodologia: A amostra foi constituída por 20 elementos seleccionados por conveniência, entre o corpo de discentes da ESS-IPS, sem história de disfunção do CAO. Foi realizada uma análise cinemática ao MS de cada sujeito, usando um aparelho de análise por varrimento electromagnético, o FOB. Em cada sujeito foram ainda medidas, as distâncias escapulares em estudo, usando a fita métrica. Cada método de medição foi constituído por dois momento (teste e reteste), em cada momento, as medidas eram recolhidas por dois investigadores distintos. Resultados e Discussão: Foram considerados como positivos os resultados que se apresentassem acima do limiar de 0,5, que classifica uma correlação como moderada a excelente. Os resultados da validade mostram que para o investigador 1 nas medidas M1e M2 apenas houve correlação com valores excelentes a moderados até aos 30º de elevação do MS. Já para M3 apenas aos 30º no plano da omoplata essa mesma correlação não tem valores próximos do cutpoint. Em M4 nenhum valor tem correlação significativa com os valores do FOB, chegando mesmo a haver correlação negativa para os 120º no plano da omoplata. Em M5 apenas os 0º mostram valores correlacionais excelentes a moderados. Para o investigador 2, em M1 e M2 á semelhança do investigador 1, só existem valores de correlação significativos até aos 30º de elevação do MS. Já para M3 todos os valores mostram excelente a moderada correlação á excepção dos 120º no plano frontal. Em M4 este investigador apresenta maus resultados. Já em M5 os valores de correlação são moderados aos 0º e aos 90º. No que diz respeitos aos resultados dos CCI intra-observador,podemos afirmar que foi em M5 que estes valores mais se aproximaram do cut point. M1 e M2 são as medidas onde se encontram resultados menos satisfatórios. É aos 60º que existem valores mais satisfatórios, seguidos pelos 0º e 30º, quando nos aproximamos de graus mais elevados, como 90º e 120º, estes valores tendem a baixar. Quanto á fidedignidade inter-observador para M1 apenas aos 90º e aos 120º houve valores de correlação abaixo do cutpoint. Em M2, só os 60º do plano sagital não teve valores acima do cutpoint, em M3 apenas os 30º plano sagital não obtiveram valores acima do cut-point, o mesmo acontece para M3 aos 30º plano da omoplata e em M5 aos 30º e 120º no plano frontal. Conclusão: Os resultados deste estudo indicam que a metodologia em causa apresenta elevado grau de fidedignidade inter-observador, já no que toca é fidedignidade intra-observador o grau de semelhança não é tão elevado. Também o erro associado á medida não ultrapassou 1,5cm, sendo considerado baixo. Na validade concorrente concluímos que é aos 0º que a metodologia se torna uma opção válida na aferição das distâncias medidas com uma boa a excelente concordância com o FOB. As medidas consideradas como opções válidas, nas diferentes amplitudes, podem funcionar como parâmetros clínicos de caracterização do posicionamento da omoplata, podendo vir a contribuir ainda para a caracterização da orientação da mesma.-------------------- ABSTRACT:Introduction: The kinematic relationship between the joints of the CAO has great importance in the function of MS, which is why more and more investigated and described. The positioning of the blade gets an important role in understanding the DCAO. There is no doubt the important role of the scapula in the dynamics of MS as well as the positioning of scapular dysfunction as a clinical parameter of the CAO. All these factors create the need to develop tools for evaluating the place of articulation ET. Most assessment tests, restrict its assessment to GU joint disorders, not incorporating a more dynamic and interactive way that respects the theoretical assumptions inherent in the REU. It is also important that the methods are easy to apply clinical and reliably to assess the validity and outcomes. Objectives: To contribute to the development of a methodology for evaluating the scapula in different ranges of MS, through the study of concurrent validity, reliability of intra-and inter-observer. Methodology: The sample consisted of 20 selected elements for convenience, between the body of students of IPS-ESS with no history of dysfunction of the CAO. We performed a kinematic analysis of each subject to MS, using a scanning device for electromagnetic analysis, the FOB. In each subject were also measured, the scapular distances under study, using tape measure. Each method of measuring the time consisted of two (test and retest), in each moment, the measures were collected by two different investigators. Results and Discussion: We considered as positive results that were above the threshold of 0.5, which ranks as a moderate to excellent correlation. The results show that the validity for the researcher in an action M1e M2 was only correlated with moderate to excellent values up to 30º of elevation of the MS. As for M3 only to 30º in the plane of the scapula has the same correlation values near the cutpoint. M4 has no value in correlation with the values of the FOB, and even negative correlation to 120 ° in the plane of the scapula. In M5 show only the values 0 ° correlational excellent to moderate. For investigator 2 in M1 and M2 will be like an investigator, there are only significant correlation values up to 30º of elevation of the MS. As for M3 all the values show excellent correlation to moderate with the exception of 120 ° in the frontal plane. In this researcher M4 has bad results. M5 already in the correlation values are moderate to 0º and 90 º. Regarding the results of ICC intra-observer, we can say that M5 was that these values come closest to the cut point. M1 and M2 are measures which are less than satisfactory results. At 60 ° there are more satisfactory values, followed by 0º and 30º, when we approached the highest levels, such as 90 ° and 120 °, these values tend to decrease. The inter-observer reliability for M1 only to 90 º and 120 ºcorrelation values were below the cutpoint. In M2, only 60 of the sagital plane did not have values above the cutpoint in M3 only 30º sagital plane did not obtain values above the cut-point, the same goes for M3 at 30 ° plane of the scapula and M5 at 30 º and 120 º in frontal plane. Conclusion: The results of this study indicate that the methodology in question has a high degree of inter-observer reliability, as far as intra-observer reliability is the degree of similarity is not as high. Also the error of measure did not exceed 1.5 cm, and is considered low. In concurrent validity conclude that it is at 0 ° the methodology becomes a valid option for the measurement of distances measured with a good to excellent agreement with the FOB. The measures considered as valid options in different amplitudes, can function as clinical parameters to characterize the positioning of the shoulder blade and could further contribute to the characterization of the orientation of the same.

Custos diretos do tratamento do cancro do cólon no Algarve

RESUMO - O cancro colorretal é um dos tumores mais comuns nos países desenvolvidos e um grave problema de saúde pública. Em Portugal constitui a terceira causa de morte por cancro em ambos os sexos e a segunda para cada sexo separadamente. A sua importância tem vindo a aumentar devido aos custos pessoais e sociais, surgindo internacionalmente como a segunda doença oncológica com os custos económicos mais elevados. No contexto atual, onde os gastos continuam a aumentar e os recursos são limitados, é importante tornar acessível aos decisores políticos o valor dos custos do cancro do cólon, para comparar opções para a prevenção e tratamento desta doença, no momento de afetar os recursos e financiamento do cancro. O objetivo do estudo é medir os custos diretos do tratamento do cancro do cólon na região do Algarve no ano de 2007. Para além da caracterização sociodemográfica e clínica dos doentes, pretende-se relacionar os custos das diferentes tipologias de diagnóstico e tratamento com os estádios da doença, com a idade e com o sexo. Propõe-se um estudo retrospetivo, analítico, transversal, que segue a abordagem custos da doença baseada na prevalência, adotando a perspetiva dos serviços de saúde. A principal fonte dos dados é a plataforma do ROR-Sul, extraindo-se a população constituída por todos os doentes com diagnóstico de cancro do cólon entre 1 de janeiro de 2007 e 31 de dezembro de 2007, residentes no distrito de Faro (n=170). Para a valorização dos custos recorre-se às Portarias que regulam as tabelas de preços dos serviços do Sistema Nacional de Saúde, à contabilidade analítica dos hospitais e ao Infarmed. Os resultados serão analisados através do Statistical Program for Social Sciences (SPSS) versão 20. De forma a verificar a existência de diferenças estatísticas, em termos de médias e da existência de relações, entre as variáveis sociodemográficas e clínicas utilizaram-se vários testes. Consideramos que este estudo será um importante ponto de partida para posteriores análises económicas completas, em termos dos seus custos e suas consequências, nomeadamente a realização da análise custo-efetividade de programas de prevenção primária e secundária do cancro do cólon.

Cost-Effectiveness of Non-Vitamin K Antagonist Oral Anticoagulants for Atrial Fibrillation in Portugal

INTRODUCTION AND OBJECTIVES:Recently, three novel non-vitamin K antagonist oral anticoagulants received approval for reimbursement in Portugal for patients with non-valvular atrial fibrillation (AF). It is therefore important to evaluate the relative cost-effectiveness of these new oral anticoagulants in Portuguese AF patients. METHODS: A Markov model was used to analyze disease progression over a lifetime horizon. Relative efficacy data for stroke (ischemic and hemorrhagic), bleeding (intracranial, other major bleeding and clinically relevant non-major bleeding), myocardial infarction and treatment discontinuation were obtained by pairwise indirect comparisons between apixaban, dabigatran and rivaroxaban using warfarin as a common comparator. Data on resource use were obtained from the database of diagnosis-related groups and an expert panel. Model outputs included life years gained, quality-adjusted life years (QALYs), direct healthcare costs and incremental cost-effectiveness ratios (ICERs). RESULTS:Apixaban provided the most life years gained and QALYs. The ICERs of apixaban compared to warfarin and dabigatran were €5529/QALY and €9163/QALY, respectively. Apixaban was dominant over rivaroxaban (greater health gains and lower costs). The results were robust over a wide range of inputs in sensitivity analyses. Apixaban had a 70% probability of being cost-effective (at a threshold of €20 000/QALY) compared to all the other therapeutic options. CONCLUSIONS:Apixaban is a cost-effective alternative to warfarin and dabigatran and is dominant over rivaroxaban in AF patients from the perspective of the Portuguese national healthcare system. These conclusions are based on indirect comparisons, but despite this limitation, the information is useful for healthcare decision-makers.

Endoscopic Treatment of Early Gastric Obstruction After Sleeve Gastrectomy: Report of Two Cases

Morbid obesity is an epidemic and complex disease which imposes a multidisciplinary approach. Laparoscopic sleeve gastrectomy has become a frequent procedure given its effi- cacy and safety compared to other surgical options. However, it isn’t free from complications. Lax gastric fixation or incorrect positioning of the stomach during surgery can result in early gastric outlet obstruction caused by a volvulus-like mechanism by rotation of the stomach around its anatomic axes. This report refers to two cases of post sleeve gastric torsion resulting in persisting vomiting after initiating oral intake. The diagnosis was confirmed by upper gastrointestinal-contrast study and gastroscopy. In both cases, a fully covered self-expandable metallic stentwas insertedwhich prompted the gastric lumen to become permeable resulting in symptomatic resolution. The stents were removed endoscopically aftertwo and three months. Beyond more than three years offollow-up,the patients remain asymptomatic and no recurring ‘‘stenosis’’ was noticed.In these cases the use offully covered self-expandable metallic stents demonstrated to be effective and safe in the treatment of post sleeve gastric torsion.

Spectrum and Frequency of GJB2 Mutations in a Cohort of 264 Portuguese Nonsyndromic Sensorineural Hearing Loss Patients

OBJECTIVE: To assess the spectrum and prevalence of mutations in the GJB2 gene in Portuguese nonsyndromic sensorineural hearing loss (NSSHL) patients. DESIGN: Sequencing of the coding region, basal promoter, exon 1, and donor splice site of the GJB2 gene; screening for the presence of the two common GJB6 deletions. STUDY SAMPLE: A cohort of 264 Portuguese NSSHL patients. RESULTS: At least one out of 21 different GJB2 variants was identified in 80 (30.2%) of the 264 patients analysed. Two mutant alleles were found in 53 (20%) of these probands, of which 83% (44/53) harboured at least one c.35delG allele. Twenty-seven (10.2%) of the probands harboured only one mutant allele. Subsequent analysis revealed that the GJB6 deletion del(GJB6-D13S1854) was present in at least 7.4% (2/27) of the patients carrying only one mutant GJB2 allele. Overall, one in five (55/264) of the patients were diagnosed as having DFNB1-related NSSHL, of which the vast majority (53/55) harboured only GJB2 mutations. CONCLUSIONS: This study provides clear demonstration that mutations in the GJB2 gene are an important cause of NSSHL in Portugal, thus representing a valuable indicator as regards therapeutical and rehabilitation options, as well as genetic counseling of these patients and their families.
