RESUMO

Electronic systems are increasingly present in the healthcare system and are often related to improved medical care. However, the widespread use of these technologies ended up building a relationship of dependence that can disrupt the doctor-patient relationship. In this context, digital scribes are automated clinical documentation systems that capture the physician-patient conversation and then generate the documentation for the appointment, enabling the physician to engage with the patient entirely. We have performed a systematic literature review on intelligent solutions for automatic speech recognition (ASR) with automatic documentation during a medical interview. The scope included only original research on systems that could detect speech and transcribe it in a natural and structured fashion simultaneously with the doctor-patient interaction, excluding speech-to-text-only technologies. The search resulted in a total of 1995 titles, with eight articles remaining after filtering for the inclusion and exclusion criteria. The intelligent models mainly consisted of an ASR system with natural language processing capability, a medical lexicon, and structured text output. None of the articles had a commercially available product at the time of the publication and reported limited real-life experience. So far, none of the applications has been prospectively validated and tested in large-scale clinical studies. Nonetheless, these first reports suggest that automatic speech recognition may be a valuable tool in the future to facilitate medical registration in a faster and more reliable manner. Improving transparency, accuracy, and empathy could drastically change how patients and doctors experience a medical visit. Unfortunately, clinical data on the usability and benefits of such applications is almost non-existent. We believe that future work in this area is necessary and needed.

RESUMO

BACKGROUND: With the progression of the Coronavirus disease pandemic, the number of mutations in the viral genome has increased, showing the adaptive evolution of severe acute respiratory syndrome coronavirus 2 in humans and intensification in transmissibility. Long-term infections also allow the development of viral diversity. In this study, we report the case of a child with severe combined immu presenting a prolonged severe acute respiratory syndrome coronavirus 2 infection. We aimed to analyze 3 naso-oropharyngeal swab samples collected between August and December 2021 to describe the amino acid changes present in the sequence reads that may have a role in the emergence of new viral variants. METHODS: The whole genome from clinical samples was sequenced through high throughput sequencing and analyzed using a workflow to map reads and then find variations/single-nucleotide polymorphisms. In addition, the samples were isolated in cell culture, and a plaque forming units assay was performed, which indicates the presence of viable viral particles. RESULTS: The results obtained showed that the virus present in all samples is infectious. Also, there were 20 common mutations among the 3 sequence reads, found in the ORF1ab and ORF10 proteins. As well, a considerable number of uncommon mutations were found. CONCLUSIONS: In conclusion, we emphasize that genomic surveillance can be a useful tool to assess possible evolution signals in long-term patients.

RESUMO

Antineoplastic treatments can negatively affect body composition, leading to metabolic derangements and worse clinical outcomes in breast cancer patients. This scoping review assesses body adiposity changes during breast cancer therapy. We included clinical and observational studies, published until the last search date in any language, with women aged >18 years, after breast cancer diagnosis, at any clinical stage and with any history of breast cancer treatment, who had body adiposity quantified by imaging tools at least twice during follow-up. In total, 17 studies were included (n = 1,009 individuals), six of which found a significant increase in body adiposity during treatment, two found a significant decrease, one presented divergent findings according to the imaging method and the analyzed body adiposity depots, and eight studies found no significant change in the outcome. Selective estrogen receptor modulators were associated with increased body adiposity, whereas aromatase inhibitors were associated with its decrease (n = 3). Chemotherapy was associated with increased body adiposity (n = 1), and monoclonal antibody with reduced brown adipose tissue activity (n = 1). Breast cancer treatment may have different effects on body adiposity, according to its mechanisms and protocols. Further studies are necessary to better elucidate this scenario.

RESUMO

PURPOSE: Randomized clinical trials (RCT) are inconclusive regarding the role of dietary interventions in anthropometric measurements and survival in breast cancer patients. Our aim was to conduct a systematic review and meta-analysis to assess the effects of diet on these outcomes in women treated for early-stage breast cancer. METHODS: Embase, MEDLINE, the Cochrane Database of Systematic Reviews, and the Cochrane Central Register of Controlled Trials were searched for RCT comparing dietary interventions (individualized dietary counseling, prescription of a specific diet, or others) with usual care in women that were treated for early breast cancer. Primary outcomes were overall survival (OS) and disease-free survival (DFS); secondary outcome was a change in body mass index (BMI). RESULTS: We found 12 RCT eligible for analysis, 7 of which were included in the quantitative analysis. Two studies reported OS and DFS and 6 reported BMI data. The hazard ratio (HR) for OS and DFS was 0.91 (95% confidence interval [CI] 0.77-1.07, p = 0.25) and 0.92 (95% CI 0.79-1.08, p = 0.31) for the intervention and control groups, respectively. Intervention was associated with BMI reduction in subjects who received a specific diet instead of counseling or other types of intervention (-0.67; 95% CI -1.14 to -0.21). CONCLUSIONS: Despite increasing survival among breast cancer patients due to better oncological treatments, there is still a lack of prospective data regarding the effects of dietary interventions in this population. We found positive association between prescription of specific diets in terms of anthropometric measures; there were no differences in OS or DFS.

RESUMO

OBJECTIVES: This study aimed to estimate the prevalence of genital, anal and oral HPV infection in Brazil through systematic review and meta-analysis. METHODS: We searched EMBASE, LILACS, MEDLINE, Web of Science and SciELO from inception to December 2018. Original research articles that assessed the prevalence of genital (i.e., cervical, penile), anal and oral HPV infection in Brazil were selected in pairs by independent authors. No sex, age, HPV vaccination, language or date restrictions were applied. HPV prevalence was estimated and stratified according to risk factors population and by geographic area throughout the country. The study prevalence was pooled using a random effects model. Analysis was performed using R (version 3.5.2), packages meta version 4.9-4 and metaphor 2.0-0. This review is registered on PROSPERO under protocol number CRD42016032751. RESULTS: We identified 3,351 references. After the screening process, 139 of them were eligible for this systematic review (57,513 total participants). Prevalence of cervical HPV was 25.41% (95% CI 22.71-28.32). Additionally, prevalence was 36.21% (95% CI 23.40, 51.33) in the penile region, 25.68% (95%CI 14.64, 41.04) in the anal region, and 11.89% (95%CI 6.26, 21.43) in the oral region. Subgroup analysis showed prevalence in each anatomic site was higher in high-risk populations. CONCLUSION: The prevalence of HPV is high in the Brazilian population and varies by population risk and anatomic body site, with lower rates in the oral cavity compared to that in the cervical, penile and anal region. Studies on HPV have primarily been developed to evaluate infection and cancer in the cervical region. There is a profound lack of HPV data in many geographic regions of Brazil and for different anatomic sites.

RESUMO

INTRODUCTION: Human papillomavirus (HPV) is the most common sexually transmitted infection and is associated with several types of cancer. The number of cases of HPV-associated head and neck squamous cell carcinomas (HNSCCs), especially oropharyngeal carcinomas, has increased significantly in recent years despite decreased tobacco smoking rates. Currently, no data concerning the risk factors and prevalence of HPV in HNSCC patients in all regions of Brazil are available, making it difficult to promote advances in this field of public health. Therefore, our goal is to determine the impact of infection by HPV, including HPVs with different genotypes, on head and neck cancer and the risk factors associated with the development of head and neck cancer in all regions of Brazil. METHODS AND ANALYSIS: This is a case-control study that will include 622 patients and 622 controls from all regions of Brazil. A questionnaire will be applied to gather information on sociodemographic, behavioural and health factors. Oral, cervical or penile/scrotal, and anal specimens and serum samples will be collected from all participants. Formalin-fixed paraffin-embedded tissue from tumour biopsies will be analysed only in the case group. Molecular and serological analyses will be performed to evaluate the presence and role of HPV in the development of head and neck cancer. ETHICS AND DISSEMINATION: This project was approved by the research ethical committee of the proposing institution (Hospital Moinhos de Vento, number 2.852.060). Ethical approval from the collaborators is currently under evaluation and is not yet complete. The results of this study will be presented at meetings with the Brazilian Ministry of Health through technical reports and to the scientific community at national and international events, with subsequent publication of scientific articles.

RESUMO

INTRODUCTION: Human papillomavirus (HPV) infection is transmitted through skin-to-skin contact, and vaginal and anal sex are the most common transmission routes. Sex workers and men who have sex with men (MSM) are more exposed to the virus, and therefore, a higher frequency of this infection would be expected. The prevalence of HPV infection types and the forms and factors of transmission must be investigated to control infection-related outcomes. This protocol study will be the first nationwide study with a uniform methodology to evaluate HPV prevalence of and infection types among sex workers and MSM in Brazil. METHODS AND ANALYSIS: This multicentre cross-sectional study will be conducted with a respondent-driven sampling method to recruit 1174 sex workers and 1198 MSM from all regions of Brazil. The study will consist of preliminary interviews to verify the eligibility criteria and characterise the network size as well as a second questionnaire to obtain sociodemographic, behavioural and sexual information. Specimens from the oral cavity and anal and cervical or penile/scrotal sites will be collected. All HPV samples will be processed in a certified central laboratory. Other sexually transmitted infections will be evaluated by interview and by rapid testing for HIV and syphilis. Strict quality control will be conducted using different procedures, including the training and certification of the health professionals responsible for acquiring data and monitoring visits. ETHICS AND DISSEMINATION: The project was approved by the research ethics committee of the main institution and the corresponding ethics committees of the recruitment sites. Due to the literature gap on the sexual health of sex workers and MSM and the intense stigma surrounding these populations, a critical analysis of the study results will contribute to epidemiological knowledge and will be useful for the development of strategies against virus morbidities.

RESUMO

Choice of treatment for newly diagnosed transplant-ineligible multiple myeloma poses a difficult task due to an ever-increasing plethora of different regimens. Attempting to clarify this subject, we performed a systematic review and Bayesian network meta-analysis of 29 randomized clinical trials, enrolling 14,533 patients, and comparing 25 different treatment regimens regarding overall survival(OS), progression-free survival(PFS), complete response(CR), overall response rate(ORR) and toxicity. Head-to-head comparisons for all regimens and ranking of best treatments are reported. OS analysis showed superiority of lenalidomide(R) and bortezomib(V) containing regimens over thalidomide(T) protocols (e.g. Rd/CTD-HR:0.7;95%CrI:0.53-0.93, VMP/TD-HR:95%0.45;CrI:0.29-0.69). Concerning PFS, daratumumab(D) plus V (Dara-VMP) showed superior results over R (e.g. Dara-VMP/MPR-HR:0.52;95%CrI:0.34-0.77), V plus T (Dara-VMP/VTd-HR:0.56;95%CrI:0.37-0.65) and T (Dara-VMP/CTD-HR:0.34;95%CrI:0.23-0.49) containing regimens. Also, VRd and VMPT-VT performed well over other regimens. Dara-VMP showed superior response rates over R (ORR Dara-VMP/MPR-RR:6.27;95%CrI:2.18-18.95, CR Dara-VMP/MPR-RR:1.53;95%CrI:1.21-1.96) and T (ORR Dara-VMP/MPT-T-RR:4.05;95%CrI:1.19-13.26, CR Dara-VMP/MPT-T-RR:1.42;95%CrI:1.09-1.85; ORR Dara-VMP/CTD-RR:2.72;95%CrI:1.2-6.31, CR Dara-VMP/CTD-RR:1.2;95%CrI:1.05-1.36) including a higher rate of complete remission even when compared to VRd (RR:1.29;95%CrI:1.01-1.66). A higher rate of grade 3-4 adverse events was found for RD and CPR (thrombotic); VTd, VTP and VMPT-VT (neurological); RD and VAD (infectious); MPR-R and VAD (hematological); Vd and VTd (gastrointestinal); VAD, VMPCc and RD (cardiovascular). These results confirm obsolescence of classical regimens (such as VAD and MP) while pointing out benefits in efficacy resulting from incorporation of quadruplets and triplets combining new agents (Dara-VMP, VRd and VMPT-VT) and supports current rational of treatment until progression or prohibitive toxicity, especially when including lenalidomide. Based on this data, we would recommended incorporation of strategies combining novel agents (monoclonal antibodies, immunomodulatory imide drugs and proteasome inhibitors) in triplets or quadruplets and/or those comprising long term use of lenalidomide as standard frontline treatments. Moreover, this study settles daratumumab's place as an attractive alternative for upfront treatment.

RESUMO

Investigation of hyperferritinemia in metabolic syndrome patients represents a diagnostic challenge, but it is essential for the identification of individuals with iron overload. Hepcidin negatively regulates iron absorption and release. An increase in hepcidin occurs when iron levels are sufficient or in inflammatory states, conditions often associated with hyperferritinemia. Hemochromatosis causes hyperferritinemia due to iron overload, but frequently has low hepcidin levels. Our aim was to evaluate biochemical and molecular parameters related to iron metabolism in patients with metabolic syndrome. We evaluated 94 patients with metabolic syndrome according to the International Diabetes Federation criteria in a cross-sectional study. Anthropometric data and diagnostic criteria for metabolic syndrome, iron dosage, ferritin, transferrin saturation, hepcidin, and the C282Y and H63D mutations in the HFE hemochromatosis gene were evaluated. Prevalence of hyperferritinemia in the study population was 27.7% and was higher in males (46.2%) than in females (14.5%). Increase in transferrin saturation correlated with mutations in the hemochromatosis gene. Hyperferritinemia was associated to transferrin saturation and hepcidin after logistic regression analysis. In conclusion, hyperferritinemia is a frequent finding in metabolic syndrome patients, most frequently in men; and hepcidin assessment can be useful for the investigation of ferritin increase in those subjects.

RESUMO

Autologous transplantation continues to be the cornerstone of younger and fit multiple myeloma patients. It is known that frontline induction therapy before transplantation can influence post-transplant results. Therefore, best frontline treatment for transplant-eligible patients should be based on best available evidence to guide therapy. Furthermore, until now due to data scarcity, it was not possible to thoroughly compare lenalidomide to other regimens in this setting. We performed a systematic review and network (mixed treatment comparison) meta-analysis of 21 clinical trial publications, enrolling 6474 patients and comparing 11 different treatment frontline setting regimens regarding survival, response, and safety outcomes. OS analysis showed superiority of CRD (cyclophosphamide-lenalidomide-dexamethasone) over TD-based (thalidomide-dexamethasone, HR = 0.76,0.62-0.90), VAD-based (HR = 0.71,0.52-0.90), and Z-Dex (idarubicin-dexamethasone, HR = 0.37,0.17-0.76) regimens. Concerning PFS, VTD (bortezomib-thalidomide-dexametasone) showed superior results when compared with TD-based (HR = 0.66,0.51-0.84), VAD-based (HR = 0.61,0.46-0.82), Z-Dex (HR = 0.42,0.22-0.78), and high dose dexamethasone (Dex, HR = 0.62,0.41-0.90) regimens. Bortezomib/thalidomide regimens were not superior to lenalidomide, considering these outcomes. Also, concerning complete and overall response, VTD ranked first among other regimens, showing clear superiority over thalidomide-only containing protocols. Safety outcome evaluated infectious, cardiac, gastrointestinal, neurological, thrombotic, and hematological grade 3 to 4 adverse events. Risk of thrombotic events was higher with TAD (thalidomide-doxorubicin-dexamethasone), neurological with PAD (bortezomib-doxorubicin-dexamethasone), infectious with Dex, hematological with Z-Dex, gastrointestinal with VTD, and cardiac with PAD regimens. Our study endorses current recommendations on combined immunomodulatory drugs and proteasome inhibitors frontline regimens (in triplets) in transplant-eligible multiple myeloma patients, but also formally demonstrates the favorable performance of lenalidomide in overall and progression-free survival, when compared with bortezomib/thalidomide protocols.

RESUMO

PURPOSE: Randomized clinical trials are inconclusive regarding the role of physical exercise in anthropometric measurements, quality of life, and survival in breast cancer patients. Our aim was to conduct a systematic review and meta-analysis to assess the effects of physical exercise on these outcomes in women who went through curative treatment of early-stage breast cancer. METHODS: Pubmed, Embase, Cochrane Library were searched for randomized clinical trial comparing physical exercise (counseling or structured programs with supervised/individualized exercise sessions) with usual care in women that went through for breast cancer treatment. Primary outcomes were overall survival and disease-free survival, while secondary outcomes were weight loss, body mass index, waist-hip ratio, percentage of body fat, and quality of life. RESULTS: We found 60 randomized clinical trials, only one of them showed mortality data; the HR for mortality was 0.45 (95% CI 0.21-0.97) for the intervention group when compared to the control group. Physical exercise was associated with weight reduction (- 1.36 kg, 95% CI - 2.51 to - 0.21, p = 0.02), lower body mass index (- 0.89 kg/m2, 95% CI - 1.50 to - 0.28, p < 0.01), and lower percentage of body fat (- 1.60 percentage points, 95% CI - 2.31 to - 0.88, p < 0.01). There was an increase in the quality of life (standardized mean difference of 0.45, 95% CI 0.20-0.69, p < 0.01). CONCLUSIONS: The articles found had heterogeneous types of intervention, but they showed significant effects on anthropometric measures and quality of life. Among them, only one study had mortality as outcome and it showed physical exercise as a protective intervention. Despite these findings, publication bias and poor methodological quality were presented. Physical exercise should be advised for breast cancer survivors since it has no adverse effects and can improve anthropometrics measures and quality of life. PROSPERO registry: CRD42014008743.

RESUMO

BACKGROUND: This is the second updated version of the original Cochrane review published in the Cochrane Library 2009, Issue 3. Most women with early cervical cancer (stages I to IIA) are cured with surgery or radiotherapy, or both. We performed this review originally because it was unclear whether cisplatin-based chemotherapy after surgery, radiotherapy or both, in women with early stage disease with risk factors for recurrence, was associated with additional survival benefits or risks. OBJECTIVES: To evaluate the effectiveness and safety of adjuvant platinum-based chemotherapy after radical hysterectomy, radiotherapy, or both in the treatment of early stage cervical cancer. SEARCH METHODS: For the original 2009 review, we searched the Cochrane Gynaecological Cancer Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library 2009, Issue 1), MEDLINE, Embase, LILACS, BIOLOGICAL ABSTRACTS and CancerLit, the National Research Register and Clinical Trials register, with no language restriction. We handsearched abstracts of scientific meetings and other relevant publications. We extended the database searches to November 2011 for the first update and to September 2016 for the second update. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing adjuvant cisplatin-based chemotherapy (after radical surgery, radiotherapy or both) with no adjuvant chemotherapy, in women with early stage cervical cancer (stage IA2-IIA) with at least one risk factor for recurrence. DATA COLLECTION AND ANALYSIS: Two review authors extracted data independently. Meta-analysis was performed using a random-effects model, with death and disease progression as outcomes. MAIN RESULTS: For this second updated version we identified only one small trial reporting grade 4 toxicity results, without disease-free or overall survival data with a median follow-up of 16 months.From the first updated version, we identified three trials that were ongoing, and remain so in 2016.Four trials including 401 women with evaluable results with early cervical cancer were included in the meta-analyses. The median follow-up period in these trials ranged from 29 to 42 months. All women had undergone surgery first. Three trials compared chemotherapy combined with radiotherapy versus radiotherapy alone; and one trial compared chemotherapy followed by radiotherapy versus radiotherapy alone. It was not possible to perform subgroup analyses by stage or tumour size.Compared with adjuvant radiotherapy, chemotherapy combined with radiotherapy significantly reduced the risk of death (two trials, 297 women; hazard ratio (HR) = 0.56, 95% confidence interval (CI): 0.36 to 0.87) and disease progression (two trials, 297 women; HR = 0.47, 95% CI 0.30 to 0.74), with no heterogeneity between trials (I² = 0% for both meta-analyses). Acute grade 4 toxicity occurred significantly more frequently in the chemotherapy plus radiotherapy group than in the radiotherapy group (three trials, 321 women; risk ratio (RR) 6.26, 95% CI 2.50 to 15.67). We considered the evidence for all three outcomes to be of a moderate quality, using the GRADE approach due to small numbers and limited follow-up in the included studies. In addition, it was not possible to separate data for bulky early stage disease.In the one small trial that compared adjuvant chemotherapy followed by radiotherapy with adjuvant radiotherapy alone there was no difference in disease recurrence between the groups (one trial, 71 women; HR = 1.34; 95% CI 0.24 to 7.66) and overall survival was not reported. We considered this evidence to be of a low quality.No trials compared adjuvant platinum-based chemotherapy with no adjuvant chemotherapy after surgery for early cervical cancer with risk factors for recurrence. AUTHORS' CONCLUSIONS: The addition of platinum-based chemotherapy to adjuvant radiotherapy (chemoradiation) may improve survival in women with early stage cervical cancer (IA2-IIA) and risk factors for recurrence. Adjuvant chemoradiation is associated with an increased risk of severe acute toxicity, although it is not clear whether this toxicity is significant in the long term due to a lack of long-term data. This evidence is limited by the small numbers and low to moderate methodological quality of the included studies. We await the results of three ongoing trials, which are likely to have an important impact on our confidence in this evidence.

RESUMO

BACKGROUND: This is an updated version of the original review that was first published in the Cochrane Database of Systematic Reviews 2008, Issue 4. Laparoscopy has become an increasingly common approach to surgical staging of apparent early-stage ovarian tumours. This review was undertaken to assess the available evidence on the benefits and risks of laparoscopy compared with laparotomy for the management of International Federation of Gynaecology and Obstetrics (FIGO) stage I ovarian cancer. OBJECTIVES: To evaluate the benefits and harms of laparoscopy in the surgical treatment of FIGO stage I ovarian cancer (stages Ia, Ib and Ic) when compared with laparotomy. SEARCH METHODS: For the original review, we searched the Cochrane Gynaecological Cancer Group Trials (CGCRG) Register, Cochrane Central Register of Controlled Trials (CENTRAL 2007, Issue 2), MEDLINE, Embase, LILACS, Biological Abstracts and CancerLit from 1 January 1990 to 30 November 2007. We also handsearched relevant journals, reference lists of identified studies and conference abstracts. For the first updated review, the search was extended to the CGCRG Specialised Register, CENTRAL, MEDLINE, Embase and LILACS to 6 December 2011. For this update we searched CENTRAL, MEDLINE, and Embase from November 2011 to September 2016. SELECTION CRITERIA: Randomised controlled trials (RCTs), quasi-RCTs and prospective cohort studies comparing laparoscopic staging with open surgery (laparotomy) in women with stage I ovarian cancer according to FIGO. DATA COLLECTION AND ANALYSIS: There were no studies to include, therefore we tabulated data from non-randomised studies (NRS) for discussion as well as important data from other meta-analyses. MAIN RESULTS: We performed no meta-analyses. AUTHORS' CONCLUSIONS: This review has found no good-quality evidence to help quantify the risks and benefits of laparoscopy for the management of early-stage ovarian cancer as routine clinical practice.

RESUMO

Intraosseous degenerative cysts (IDC) of the cervical spine are rare. IDC within C2 have been reported in three articles only. We report a patient with neck pain due to a IDC within C2. We discuss the differential diagnosis of these lesions and the surgical approaches to reach this complex anatomical region.

RESUMO

Although basal ganglia calcifications were described a long time ago,1,3,11 the association of leukoencephalopathy, cerebral calcifications, and cysts (LCC) is a very rare entity described in 1996.5 We present a new case of LCC and discuss clinical, neuroradiologic, and histopathologic findings regarding this association.


Mesmo que as calcificaçãoes dos núcleos da base tenham sido descritas há muito tempo atrás1,3,11 a associação com leucoencefalopatia, calcificações cerebrais e cistos (LCC) é uma entidade muito rara descrita em 1996.5 Nós apresentamos um caso novo de LCC e discutimos os achados clínicos, neurorradiológicos e histopatológicos relacionados a essa entidade.

RESUMO

Anastomoses microvasculares são um procedimento cirúrgico complexo e um armamento essencial utilizado em diversas sub especialidades. A primeira etapa de treinamento em anastomose microcirúrgica deve ser sempre no laboratório. Este artigo é uma revisão sobre os fatores envolvidos no para a realização de anastomoses microvasculares. Instrumental cirúrgico, microscópio, estrutura do laboratório, procedimentos cirúrgicos, questões éticas e parâmetros radiológicos e histológicos são discutidos.

RESUMO

STUDY DESIGN: Two case reports of a choroidal fissure cyst in the temporal horn associated with complex partial seizure. OBJECTIVES: To describe the clinical course, image findings and literature review of choroidal fissure cysts. SUMMARY AND BACKGROUND DATA: there are few reported cases of choroidal fissure cysts. RESULTS: We report two patients with complex partial seizures and temporal choroidal fissure cysts. The seizures were controlled in both patients. CONCLUSION: The choroidal fissure cyst diagnosis must highlight the importance of considering this lesion in the differential diagnosis of temporal lobe cyst and temporal lobe seizure.


DESENHO DO ESTUDO: Dois relatos de caso de cisto de fissura coroidal no corno temporal associado com crise parcial complexa. OBJETIVOS: Descrever o curso clínico, achados radiológicos e fazer uma revisão da literatura a respeito de cistos da fissura coroidal. RESUMO DOS DADOS DA LITERATURA: existem poucos casos descritos de cistos da fissura coroidal. RESULTADOS: Nós descrevemos dois pacientes com crises parciais complexas e cistos de fissura coroidal. As crises foram controladas em ambos os pacientes. CONCLUSÃO: O diagnóstico de cisto da fissura coroidal deve ser levado em conta no diagnóstico diferencial de cistos do lobo temporal e em crises de lobo temporal.

RESUMO

A tuberculose espinhal, também conhecida como Mal de Pott ou Doença de Pott, caracteriza-se como a forma mais frequente de tuberculose extrapulmonar. Apresentamos aqui o caso de uma paciente encaminhada ao Serviço de Neurologia do Hospital de Clínicas de Porto Alegre com um quadro de dois meses de evolução, apresentando sintomas de compressão medular. O diagnóstico de tuberculose espinhal foi realizado por punção guiada por tomografia computadorizada e a paciente foi submetida à drenagem do abscesso. Concomitantemente, foi iniciado o tratamento com RHZ e a paciente evoluiu com melhora dos sintomas neurológicos. Esse caso ilustra que mesmo pacientes com alterações neurológicas importantes devido à tuberculose medular podem apresentar melhora significativa com tratamento.


Spinal tuberculosis, also known as Pott's disease, is the most common form of extra-pulmonary tuberculosis. We report on a patient referred to the Division of Neurology of Hospital de Clínicas de Porto Alegre presenting with spinal cord compression symptoms for two months. The diagnosis of spinal tuberculosis was rapidly done by a computerized tomography guided biopsy. The patient was submitted to abscess surgical draining and complementary RHZ treatment, with recovery of neurological symptoms. This case illustrates that even patients with severe neurological deficits due to spinal tuberculosis may have a good outcome with the appropriate treatment.
