Pitfalls in clinical genetics

With the increasing availability of genetic tests, more doctors are offering and ordering such tests for their patients. Ordering a genetic test appears to be a simple process of filling in paperwork, drawing 3 mL of blood in an ethylenediaminetetraacetic acid tube and receiving a test report. This is identical to sending off a full blood count. However, it is far more complex than that. There are many potential pitfalls, as shown by the increasing number of complaints and lawsuits filed against doctors and allied health staff. Furthermore, clinical genetics involves more than just ordering tests; in fact, focusing on genetic tests alone is a potential pitfall. In this review, we discuss the common pitfalls in clinical genetics and how doctors can avoid these pitfalls to ensure patient safety and to safeguard their practice.

Association of preexisting hypertension with the morality in patients with systolic heart failure in Taiwan: The TSOC-HFrEF registry

Purpose To investigate the association of preexisting hypertension at admission with the mortality in patients with systolic heart failure (HF). Method We prospectively investigated the association of preexisting hypertension with the mortality among 1351 patients with HF in Taiwan during an average 12 months (range: 8 months–18 months) follow-up period. A multivariate cox regression analysis for the overall cohort and a subgroup analysis by age were performed. Results After adjustment for all potential risk factors, the associations of preexisting hypertension with cardiovascular mortality were significantly reduced in the overall cohort and those aged less than 65 years (hazard ratios (HR): 0.53, 95% confidence intervals (CI): 0.33–0.84, and 0.28, 95% CI: 0.11–0.67, respectively). However, the associations with all-cause mortality were not significantly different in these two groups (HR: 0.77, 95% CI: 0.54–1.09, and 0.59, 95% CI: 0.32–1.07, respectively). Furthermore, the associations were all nonsignificant in the patients aged older than 65 years. Conclusion Preexisting hypertension have an inverse association with cardiovascular mortality in the Asian patients with systolic HF, particularly for those with younger ages.

Effect of angiotensin receptor blockade on central aortic systolic blood pressure in hypertensive Asians measured using radial tonometry: an open prospective cohort study

<p><b>INTRODUCTION</b>Central aortic systolic pressure (CASP) has been shown to be a stronger predictor of cardiovascular events than brachial blood pressure (BP). Different classes of drugs have differential effects on CASP and brachial BP. This open prospective cohort study aimed to observe changes in CASP (measured using radial tonometry) among hypertensive Asians after 12 weeks of treatment with valsartan, an angiotensin receptor blocker (ARB).</p><p><b>METHODS</b>Patients with treatment-naïve hypertension or uncontrolled hypertension who were on non-ARB therapy were eligible for inclusion. Patients with uncontrolled BP (i.e. ≥ 140/90 mmHg) received valsartan for 12 weeks. The patients' brachial systolic and diastolic BP (SBP and DBP), and CASP changes were monitored using the BPro® watch.</p><p><b>RESULTS</b>The mean age of the 44 enrolled patients was 35 years. At baseline, the mean BP and CASP were 150.2/91.4 ± 10.6/9.4 mmHg and 136.3 ± 12.2 mmHg, respectively. Valsartan reduced SBP, DBP and CASP by 14.9 ± 10.7 mmHg, 10.9 ± 8.4 mmHg and 15.3 ± 10.9 mmHg, respectively (all p < 0.001). Every 1.0-mmHg reduction in brachial SBP resulted in a 0.8-mmHg reduction in CASP (p < 0.001). A CASP cut-off of 122.5 mmHg discriminated between controlled and uncontrolled BP (sensitivity 74%, specificity 88%).</p><p><b>CONCLUSION</b>Using radial tonometry, we demonstrated good correlation between CASP and brachial SBP reductions after 12 weeks of treatment with valsartan in our study cohort. Correlation analysis between CASP and SBP reductions may be useful for demonstrating whether a drug is able to lower CASP beyond lowering SBP.</p>

Genu Recurvatum versus Fixed Flexion after Total Knee Arthroplasty

BACKGROUND: To date, there is no study comparing outcomes between post-total knee replacement genu recurvatum and fixed flexion. This study aims to provide data that will help in deciding which side to err on when neutral extension is not achieved. METHODS: A prospective cohort study of primary total knee arthroplasties was performed, which compared the 6-month and 2-year clinical outcomes between fixed flexion and genu recurvatum deformities at 6 months. RESULTS: At 6 months, knees in genu recurvatum did better than knees in fixed flexion deformity in terms of knee flexion. However, at 2 years, knees in fixed flexion deformity did better in terms of knee scores and showed better improvement in the degree of deformity. CONCLUSIONS: We conclude that it is better to err on the side of fixed flexion deformity if neutral alignment cannot be achieved.

A randomized, controlled, crossover study in patients with mild and moderate asthma undergoing treatment with traditional Chinese acupuncture

OBJECTIVES:This study sought to verify the effects of acupuncture as an adjuvant treatment for the control of asthma.METHODS:This was a randomized, controlled, crossover trial conducted at the Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. A total of 74 patients with mild/moderate, persistent asthma were randomized into two therapeutic groups: Group A - 31 patients underwent 10 real weekly acupuncture sessions, followed by a 3-week washout period and 10 sham weekly acupuncture sessions; and Group B - 43 patients underwent 10 sham weekly acupuncture sessions, followed by a 3-week washout period and 10 real weekly acupuncture sessions. Patients used short- and long-acting β-2 agonists and inhaled corticosteroids when necessary. Prior to treatment and after each period of 10 treatment sessions, the patients were evaluated for spirometry, induced sputum cell count, exhaled nitric oxide (NO) and with the Short Form 36 (SF-36) and Questionnaire on Quality of Life-Asthma (QQLA) questionnaires. Daily peak flow and symptom diaries were registered. The level of significance adopted was 5% (α=0.05).RESULTS:In Group B, after real acupuncture, there was a decrease in eosinophils (p=0.035) and neutrophils (p=0.047), an increase in macrophages (p=0.001) and an improvement in peak flow (p=0.01). After sham acupuncture treatment, patients experienced less coughing (p=0.037), wheezing (p=0.013) and dyspnea (p=0.014); similarly, after real acupuncture, patients reported less coughing (p=0.040), wheezing (p=0.012), dyspnea (p<0.001) and nocturnal awakening episodes (p=0.009). In Group A, there was less use of rescue medication (p=0.043). After the sham procedure, patients in Group A experienced less coughing (p=0.007), wheezing (p=0.037), dyspnea (p<0.001) and use of rescue medication (p<0.001) and after real acupuncture, these patients showed improvements in functional capacity (p=0.004), physical aspects (p=0.002), general health status (p<0.001) and vitality (p=0.019). Sham acupuncture also led to significant differences in symptoms, but these were not different from those seen with real acupuncture. Spirometry and exhaled NO levels did not show a difference between sham and real acupuncture treatment. In addition, no significant difference was demonstrated between treatments regarding the quality of life evaluation.CONCLUSION:Real and sham acupuncture have different effects and outcomes on asthma control. The crossover approach was not effective in this study because both interventions led to improvement of asthma symptoms, quality of life and inflammatory cell counts. Thus, sham acupuncture cannot serve as a placebo in trials with acupuncture as the main intervention for asthma.

Oral cavity squamous cell carcinoma: factors related to occult lymph node metastasis / Carcinoma espinocelular da cavidade oral: fatores relacionados à presença de metástases linfonodais ocultas

INTRODUCTION: Elective neck dissection is recommended in cases of oral cavity squamous cell carcinoma without lymph node metastasis because of the risk of occult metastasis. OBJECTIVE: The present study aimed to evaluate predictive factors for occult lymph node metastasis in patients with oral cavity squamous cell carcinoma treated with elective neck dissection and their impact on overall and disease-free survival. METHODS: Forty surgically treated patients were retrospectively included. RESULTS: Ten cases (25%) had lymphatic metastasis. Of the studied variables, perineural and angiolymphatic invasion in addition to tumor thickness were statistically associated with lymph node metastasis. Only angiolymphatic invasion was identified as an independent risk factor for occult metastasis in the logistic regression (OR = 39.3; p = 0.002). There was no association between overall and disease-free survival with the presence of occult lymph node metastasis. CONCLUSION: Metastatic disease rate was similar to that found in the literature. Perineural and angiolymphatic invasion and tumor thickness were associated with occult metastasis, but only angiolymphatic invasion showed to be an independent risk factor .

INTRODUÇÃO: O esvaziamento cervical eletivo é realizado de maneira sistemática nos casos de carcinoma espinocelular da cavidade oral sem linfonodos clinicamente comprometidos devido à alta incidência de metástases ocultas. OBJETIVO: Avaliar pacientes com carcinoma espinocelular de cavidade oral tratados com esvaziamento cervical eletivo quanto a fatores preditivos para ocorrência de metástases ocultas e o impacto das mesmas na sobrevivência global e livre de progressão destes pacientes. MÉTODO: Quarenta pacientes cirurgicamente tratados foram avaliados em estudo retrospectivo. RESULTADOS: Dez casos (25%) apresentaram metástases ocultas. Das variáveis analisadas, invasão perineural e angiolinfática e também a espessura tumoral foram estatisticamente significantes à análise univariada. Apenas a invasão angiolinfática foi fator independente de risco de metástases ocultas pela regressão logística (OR = 39,3; p = 0,002). A presença de metástase oculta não apresentou diferença estatisticamente significante em relação às taxas de sobrevivência global e livre de progressão. CONCLUSÃO: A incidência de metástase oculta foi semelhante à literatura. A invasão perineural, angiolinfática e a espessura tumoral foram fatores associados à presença de metástase oculta, porém apenas a invasão angiolinfática apresentou-se como um fator de risco independente para ocorrência do fenômeno. .

Reducing allograft contamination and disease transmission: intraosseous temperatures of femoral head allografts during autoclaving

<p><b>INTRODUCTION</b>The Singapore General Hospital Bone Bank, which exclusively stores femoral head allografts, relies on flash sterilisation to prevent allograft-related disease transmission and wound infection. However, intraosseous temperatures during autoclaving may be lower than required to eliminate human immunodeficiency virus, and hepatitis B and C viruses. The aim of this study is to determine the intraosseous temperatures of femoral head allografts during autoclaving and to assess the adequacy of autoclaving in preventing disease transmission.</p><p><b>METHODS</b>Six femoral heads were acquired from patients who underwent hip arthroplasty. The specimens were divided into two groups. The first group underwent flash sterilisation with a sterilisation time of 4 min, while a longer sterilisation time of 22 min was used for the second group.</p><p><b>RESULTS</b>The highest core temperature in the first group was 130°C, while the core temperatures in the second group plateaued at 133°C for all allografts. In the first group, only smaller allografts maintained temperatures sufficient for the inactivation of the clinically relevant viral pathogens. In contrast, all allografts in the second group were terminally sterilised.</p><p><b>CONCLUSION</b>There is an inverse correlation between the size of allografts and intraosseous temperatures achieved during autoclaving. Therefore, we recommend dividing large allografts into smaller pieces, in order to achieve intraosseous temperatures adequate for the elimination of transmissible pathogens during flash sterilisation. Allografts should not be terminally sterilised, as the resulting allografts will become unusable. Despite modern processing techniques, stringent donor selection remains vital in the effort to prevent allograft-related infections. Autoclaving is an economical and efficacious method of preventing allograft-related disease transmission.</p>

Early experiences with robot-assisted total knee arthroplasty using the DigiMatch™ ROBODOC® surgical system

<p><b>INTRODUCTION</b>The use of robotics in total knee arthroplasty (TKA) has been shown to minimise human error, as well as improve the accuracy and precision of component implantation and mechanical axis alignment. The present study aimed to demonstrate that robot-assisted TKA using ROBODOC® is safe and capable of producing a consistent and accurate postoperative mechanical axis.</p><p><b>METHODS</b>We prospectively recruited 27 consecutive patients who underwent robot-assisted TKA between May and December 2012. Two patients were excluded from the study due to intraoperative technical problems with the robot. Long-leg radiography and computed tomography were performed prior to surgery, and used for mechanical axis measurements and component sizing. DigiMatch™ ROBODOC® Surgical System software version 4.3.6 (Curexo Technology Corp, Fremont, CA, USA) was used in all cases to perform bone cuts in accordance with the preoperative plan.</p><p><b>RESULTS</b>The postoperative coronal mechanical alignment was within 3 degrees, with a mean alignment of -0.4 ± 1.7 degrees, confirming the accuracy of the preoperative surgical plan and bone cuts. The mean operating time was 96 ± 15 min, and preoperative planning yielded 100% implant sizing accuracy.</p><p><b>CONCLUSION</b>Robotics has the potential to enable surgeons to consistently attain ideal postoperative alignment. The use of bone movement monitors and an integrated navigation system enhances the safety profile of ROBODOC® by minimising errors. However, the role of the surgeon in TKA is still vital, as the surgeon is ultimately in charge of planning the surgery, its execution and ensuring soft tissue balance during TKA.</p>

Educação médica em terapêuticas não convencionais / Medical education in non-conventional therapies

A demanda da população pela medicina alternativa e complementar (CAM) vem aumentando substancialmente nas últimas décadas, exigindo dos médicos noções básicas dessas diversas terapias, a fim de que possam orientar os pacientes em tratamentos diferentes dos que estão habituados a prescrever. Assim sendo, compete às escolas de medicina propiciar aos estudantes o conhecimento das evidências científicas, dos pressupostos teóricos e das abordagens práticas empregadas por estas distintas formas de tratamento. A presente revisão tem o propósito de fomentar a discussão sobre o ensino de terapêuticas não convencionais nas escolas de medicina, enfocando o interesse da população e da classe médica, a importância das iniciativas na graduação e na pós-graduação (residência), e as perspectivas da educação médica em terapêuticas não convencionais.

The demand of the population by complementary and alternative medicine (CAM) has been substantially increasing in the last decades, requiring that doctors have basic notions of these various therapies, in order to guide patients in different treatments of those who are accustomed to prescribe. In this way, the medical schools have the responsibility to provide to students the knowledge of scientific evidences, theoretical assumptions and practical approaches used in these different forms of treatment. The present review has the purpose of fomenting the discussion regarding the teaching of non-conventional therapeutics in medical schools. It is focused on the interest of the population and the medical class, the importance of the initiatives in undergraduate and graduate (residency), and the perspectives of medical education in non-conventional therapeutics.

Da Medicina tradicional chinesa à prática de acupuntura médica baseada em evidência / From traditional chinese medicine to the practice of acupunture based in evidence

Acupuntura é uma prática milenar que faz parte da chamada medicina tradicional chinesa. Tem sido praticada por milhares de anos na China e alguns países do continente asiático. Como tem sido descrita como efetiva no tratamento de diversas doenças e condições, a acupuntura tem sido considerada um instrumento útil na prática da saúde. Da prática primitiva até os dias de hoje, a acupuntura tem ganhado novos adeptos, atraindo assim a atenção da comunidade científica, a fim de entender melhor o seu mecanismo de ação e sua efetividade. Vários estudos têm sido feitos e publicado envolvendo acupuntura, mas há ainda controvérsia acerca de sua eficácia e efetividade. Novos estudos devem ser feitos para estabelecer o real papel da acupuntura no tratamento de diversas doenças e condições.

Acupuncture is a healing technique practiced for thousand years in China and some Asian countries, and was considered as part of Traditional Chinese medicine. As it claimed to be effective in treatment of several diseases and conditions, it has been described as useful instrument in ancient practice. From primitive to nowadays practice, acupuncture is gaining more adepts, thus attracting attention of scientific community in order to better understand its mechanism and its effectiveness. Several studies have been published concerning to acupuncture, but there is still controversy about its efficacy and effectiveness. Further studies should continue to be performed in order to establish the real role of acupuncture in treatment of several diseases and conditions.

A Singapore perspective on the use of a short course of chemothromboprophylaxis in patients who underwent total knee arthroplasty

<p><b>INTRODUCTION</b>There is considerable controversy regarding the best method to prevent venous thromboembolism. In 2008, the American College of Chest Physicians (ACCP) published specific guidelines recommending the use of ow-molecular-weight heparin or warfarin, and a target international normalised ratio of 2.0-3.0 for a duration of at least 7-10 days, after elective knee arthroplasties. Many orthopaedic surgeons believe that these recommendations are biased toward reducing deep venous thrombosis (DVT), but neglect the implicated possibility of a higher incidence of wound complications. In order to enable an objective evaluation of the fit of the ACCP recommendations to the needs of our local cohort of patients, we aimed to look at the incidence of DVT in our local population.</p><p><b>METHODS</b>This study was a prospective observational study involving existing local patients in Singapore General Hospital, Singapore, who underwent total knee arthroplasty (TKA) and were on a short course of chemothromboprophylaxis (< 7 days) after the operation. The incidence of DVT in patients was evaluated using DVT imaging 4-6 days after the operation and at one month after the operation.</p><p><b>RESULTS</b>In our study cohort, the prevalence of DVT during the period between postoperative Days 4 and 6 was 12% (11% were distal DVT and 1% was proximal DVT). Only 9% of the patients had DVT one month after the operation. Using chi-square analysis, we found that there was no significant increase in the number of DVT and pulmonary embolism cases 4-6 days and 1 month after the operation (p > 0.05).</p><p><b>CONCLUSION</b>Contrary to the ACCP guidelines, a short course of chemothromboprophylaxis post TKA, lasting no more than 7 days, is safe and adequate in the low-risk Asian population.</p>

Revision total knee arthroplasty: causes and outcomes

<p><b>INTRODUCTION</b>Local data on revision total knee arthroplasty (TKA) are limited. This study aims to assess the causes and outcomes of revision TKA in a single institution, with a 2-year follow-up.</p><p><b>MATERIALS AND METHODS</b>A retrospective review of case records of patients who underwent revision TKA in 2008 and 2009 in the authors' institution was performed. Outcome was assessed using SF-36, Oxford knee score and Knee Society Clinical Rating System preoperatively, at 6 months and at 2 years' follow-up.</p><p><b>RESULTS</b>Forty-one patients (41 knees) were included in the study. Indications for revision were aseptic loosening in 13 (31.7%), mechanical wear/component failure in 10 (24.4%), infection in 9 (22.0%), malalignment in 4 (9.8%), instability in 3 (7.3%), periprosthetic fracture in 1 (2.4%) and persistent stiffness in 1 (2.4%). Significant improvements were seen postoperatively in all 3 instruments used to evaluate clinical outcome. These improvements were seen at 6 months after surgery, and were maintained through the 2-year follow-up period. There were no significant changes in all scores between 6 months and 2 years follow-up. There was 100% survivorship of the implants with no postoperative complications requiring surgical intervention.</p><p><b>CONCLUSION</b>Indications for revision TKA locally are similar to those in other large centres. Revision total knee arthroplasty results in significantly improved function and quality of life for patients, which is maintained over a 2-year follow-up period. In our series, we obtained 100% implant survivorship.</p>

Shewanella infection of snake bites: a twelve-year retrospective study

OBJECTIVE: Infections of snake bite wounds by Shewanella are rarely discussed in the medical literature. This study aims to characterize the presentation and management of Shewanella infections in snake bite wounds. METHOD: We retrospectively investigated the microbiology, clinical features, and outcomes of patients with Shewanella infected snake bite wounds admitted to a tertiary medical center from January 1998 to December 2009. RESULTS: Ten patients with Shewanella-infected snake bite wounds were identified. All of the snake bites were caused by cobras. The majority of patients had moderate to severe local envenomation and polymicrobial infections. Shewanella isolates are susceptible to ampicillin-sulbactam, piperacillin-tazobactam, third-and fourthgeneration cephalosporins, carbapenems, aminoglycosides, and quinolones but are resistant to penicillin and cefazolin. All of the patients examined had favorable outcomes. CONCLUSION: It is recommended that Shewanella infection be considered in snake bite patients, especially when patients present with moderate to severe local envenomation.

A review of low-level air pollution and adverse effects on human health: implications for epidemiological studies and public policy

The aim of this study was to review original scientific articles describing the relationship between atmospheric pollution and damage to human health. We also aimed to determine which of these studies mentioned public policy issues. Original articles relating to atmospheric pollution and human health published between 1995 and 2009 were retrieved from the PubMed database and analyzed. This study included only articles dealing with atmospheric pollutants resulting primarily from vehicle emissions. Three researchers were involved in the final selection of the studies, and the chosen articles were approved by at least two of the three researchers. Of the 84 non-Brazilian studies analyzed, 80 showed an association between atmospheric pollution and adverse effects on human health. Moreover, 66 showed evidence of adverse effects on human health, even at levels below the permitted emission standards. Three studies mentioned public policies aimed at changing emission standards. Similarly, the 29 selected Brazilian studies reported adverse associations with human health, and 27 showed evidence of adverse effects even at levels below the legally permitted emission standards. Of these studies, 16 mentioned public policies aimed at changing emission standards. Based on the Brazilian and non-Brazilian scientific studies that have been conducted, it can be concluded that, even under conditions that are compliant with Brazilian air quality standards, the concentration of atmospheric pollutants in Brazil can negatively affect human health. However, as little discussion of this topic has been generated, this finding demonstrates the need to incorporate epidemiological evidence into decisions regarding legal regulations and to discuss the public policy implications in epidemiological studies.

The teaching of acupuncture in the University of São Paulo School of Medicine, Brazil / O ensino da acupuntura na Faculdade de Medicina da Universidade de São Paulo, Brasil

OBJECTIVE: Since being introduced as an elective discipline (non-obligatory) in the second semester of 2002, acupuncture has been taught in the University of São Paulo School of Medicine. We conducted this study to verify interest and acceptance among under graduate medical students and to discern a positive influence contributing to improveing their skills. METHODS: The study was conducted from 2002 to 2007 using descriptive statistical methods. RESULTS: The average number of students who concluded the discipline is 24.9 students per semester with an average number of medical students per semester of 87.5 (28 percent of all medical students in the 7th and 8th semesters). After a semester of basic training in acupuncture, only eight students per group are promoted (after selection) to the Medical Academic League of Acupuncture which lasts for two years. Every semester, all eight vacancies are filled. Among the students who concluded the course, 98 percent described course quality as good or very good, 85 percent considered themselves at least partially able to use acupuncture and 79 percent stated that the course influenced them in their medical education. CONCLUSION: There is a genuine interest to learn acupuncture, almost 30 percent of all students volunteer for a brief training in acupuncture while some of them choose additional training of two years indue to the importance of acupuncture as part of professional skills. Results indicate that acupuncture should be included as an elective discipline for medical students.

OBJETIVO: Após ter sido introduzida como disciplina eletiva (não obrigatória) no segundo semestre de 2002, a acupuntura tem sido ensinada na Faculdade de Medicina da Universidade de São Paulo (FMUSP) desde então. Esse estudo foi realizado com o intuito de verificar o interesse e a aceitação da acupuntura entre os estudantes de medicina da FMUSP e se, de alguma forma, ela poderia influenciá-los positivamente, contribuindo para melhorar as suas competências. MÉTODOS: O estudo foi conduzido durante o período de 2002 a 2007, utilizando-se métodos de estatística descritiva. RESULTADOS: A média de todos os estudantes que concluíram a disciplina foi de 24,9 alunos por semestre, sendo que a média de estudantes de medicina por semestre é de 87,5 (28 por cento de todos os estudantes de medicina nos 7º e 8º semestres). Após o primeiro semestre de formação básica em acupuntura, apenas oito alunos por grupo são promovidos (após seleção) para a Liga Médica Acadêmica de Acupuntura, que tem a duração de dois anos. Em todos os semestres, as oito vagas são preenchidas. Entre os estudantes que concluíram o curso, 98 por cento consideraram-no de boa ou muito boa qualidade, 85 por cento consideravam-se parcialmente capazes para empregar a acupuntura e 79 por cento consideraram que o curso contribuiu para a sua educação médica. CONCLUSÃO: Existe um real interesse para a aprendizagem da acupuntura, pois em torno de 30 por cento de todos os alunos quiseram passar por um breve treinamento em acupuntura, alguns deles optando por uma formação de dois anos em reconhecimento à importância da acupuntura como parte da capacitação profissional. Os resultados sugerem que a acupuntura deve ser incluída como uma disciplina eletiva para alunos de medicina.
