RESUMO
INTRODUCTION: Myasthenia gravis (MG) is an autoimmune, neurologic disease that causes a wide range of symptoms. While the transsternal, transcervical and thoracotomy approaches are accepted as effective, there is still debate regarding the VATS approach. MATERIALS AND METHODS: We analyzed our center's surgical experience with thymectomy for myasthenia gravis, comparing the results of patients operated on using VATS and more invasive approaches, over a period of 10 years. A search of the department's surgical database for myasthenia gravis cases between January 2010 and January 2021, revealed a total of 40 cases. Twenty-four patients were included in the final analysis and were distributed into two groups: the VATS procedure group (group A) and the open procedure group (group B). The latter included sternotomy, thoracotomy, transcervical and hemiclamshell approaches. Only radical thymectomies were included. The established outcomes were clinical improvement defined as asymptomatic remission, reduction, or discontinuation of the medication necessary to achieve optimal symptom control. RESULTS: The median follow-up time was 27 months (ranging from 4 to 75 months). Videothoracoscopy radical thymectomy was performed on 12 patients. Complete remission with no medication was achieved in 1 case (8.3%), while 2 patients (16.7%) became asymptomatic with reduced medication. An improvement (reduced symptoms or decreased medication) was observed in 8 cases (66.6%). No change in clinical outcome was noted in 1 patient (8.3%). None of the patients reported worsening symptoms. Open thymectomy was performed on 12 patients. Complete remission with no medication was achieved in 1 case (8.3%), while 2 patients (16.7%) became asymptomatic with reduced medication. An improvement was noted in 6 cases (50%). No change in clinical outcome was observed in 3 patients (25%) whereas 2 of them (16.7%) experienced slightly better symptom control but with a significant increase in medication. One patient (8.3%) described the clinical results as without any significant change. None of the patients reported worsening symptoms. CONCLUSION: The videotoracoscopic approach in the treatment of myasthenia gravis is non-inferior compared to the open approach and effective in a long-term follow-up, offering all the additional benefits of less invasive surgery.

Oligobregma represents the most speciose genus of Scalibregmatidae with 17 valid species. Most of them occur at great depths and are found living on soft bottoms. Here, we present the descriptions of O. nonatoi sp. nov., O. cruzae sp. nov., and O. bakkeni sp. nov., sampled from the Brazilian continental shelf and slope, and a key to all species of Oligobregma. O. nonatoi sp. nov. differs from its congeners by the presence of a triangular prostomium with short rounded horns, acicular spines on notopodia of chaetigers 14 and on neuropodia of chaetigers 13. Oligobregma cruzae sp. nov. can be distinguished by the presence of a quadrangular prostomium with two short, rounded horns, acicular spines on chaetigers 14, and lyrate chaetae from chaetiger 5. Finally, O. bakkeni sp. nov. is unique among its congeners by the presence of acicular spines with rounded tips. This is the first record of this genus along the Brazilian coast and the specimens were collected on Esprito Santo, Campos and Santos sedimentary basins, both located in Brazilian southeast region. The sampling campaigns were carried out in scientific expeditions related to two research projects: Santos Project Santos Basin Environmental Characterization and Ambes Project Esprito Santo Basin Assessment Project, both coordinated by CENPES/PETROBRAS.

We report a case of a 67-years old non-smoking female diagnosed with hypertension when 24-years-old and complicated with chronic kidney and hypertensive heart diseases. On CT-Chest an incidental discovery of a lesion (16x14x23mm) adjacent to the abdominal aorta was made. Initially suspected to be paraganglioma, a hypothesis which the subsequent MRI did not exclude. Urine analysis showed normal Metanephrine with slightly elevated Chromogranin-A levels. During VATs-procedure "bulging" below the adventitial layer of the descending aorta at the level of the diaphragmatic gutter was identified. By opening the adventitia, a lipomatous lesion with a nodular, consistent center was identified and excised. Final histopathological report confirmed the diagnosis of lymph node not suggestive of neoplasia. Currently, 12 months after the surgery, the patient's condition is good being under surveillance in the Thoracosurgical Outpatient Clinic. Despite not having identified any neuroendocrine component, the patient had clinical signs of clear improvement of arterial hypertension.

Scalibregmatidae Malmgren, 1867 is a relatively small family of annelids, with only two taxa reported to Brazil. In this work, we expand the scientific knowledge of this group by presenting two new Scalibregma Rathke, 1843 species. The new species S. lanai sp. nov. and S. cinthyae sp. nov. were collected during an expedition to the Campos and Santos oceanographic basins. Scalibregma cinthyae sp. nov. is unique among its congeners by the presence of two rows of paired lobes on the mouths upper and lower lips, whereas S. lanai sp. nov. is unique among its congeners by the presence of two rows of paired lobes on the mouths lower lip, branchiae from chaetigers 35, and lyrate chaetae with equal tynes. We provide an identification key to all Scalibregma species.

The need for complete resection of chest wall tumors creates a huge challenge in terms of reconstructing the complex dynamics of the thorax. We are reporting a case of a low-grade fibromyxoid sarcoma (LGFMS) diagnosed in a young male, where the complete resection of the mass, sternum and parcially the pericardium was performed. Subsequently, a composite porous high-density polyethylene StarPore® prosthesis of the sternum and costal arches was used and the latissimus dorsi muscle free flap with skin graft was implanted over the sternum.

The unprecedented mononucleated ligand (6,6-di(1H-indol-3-yl)-N,N-bis(pyridin-2-ylmethyl)hexan-1-amine (LC5) with an N3-donor set and its complexes [Zn(LC5)Cl2] ⢠2CH3OH (1) and [Zn(LC5)2](ClO4)2 (2), were successfully prepared. All compounds were fully characterized by a suite of physicochemical methods. Fluid 1H and 13C NMR spectroscopy, as well as DFT and TD-DFT calculations, were carried out to propose a viable structural arrangement for both complexes. The interaction between these compounds and DNA was monitored in the UV region where binding constants (Kb) were estimated (2 > 1 > LC5). These data were corroborated by DNA cleavage assays using groove binders, circular dichroism, and docking studies. Both complexes confirmed their biocide activity against selected microorganisms: Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria, the filamentous fungi A. fumigatus and S. cerevisiae. Finally, the cytotoxic activities of 1 and 2 were tested against the erythroleukemia K562 cell line. For all biological studies, it was probed that the presence of the indole moieties and the zinc atoms in the chemical composition of the complexes studied could increase the magnitude of the activity following the order: 2 > 1 > LC5, where a linear relationship between the biological activity upon K562 cells (IC50) and DNA binding studies (Kb) was found.

We report an electrochemical oxidative intramolecular cyclization reaction between 2-alkynylphenol derivatives and different diselenides species to generate a wide variety of substituted-benzo[b]furans. Driven by the galvanostatic electrolysis assembled in an undivided cell, it provided efficient transformation into oxidant-, base-, and metal-free conditions in an open system at room temperature. With satisfactory functional group compatibility, the products were obtained in good to excellent yields.
RESUMO
An 18-year-old boy presented with a giant midline mass with 9 years of evolution. The tumor was excised, and reconstruction made with a customized sternum implant and a free latissimus dorsi muscle flap with skin graft. Histological analysis was compatible with low-grade fibromyxoid sarcoma (LGFMS).
RESUMO
INTRODUCTION: Mediastinal staging is a hot topic in thoracic oncology. According to the guidelines, and besides other criteria, in the presence of a primary lung cancer with increased mediastinal lymph node uptake on PET-CT, a negative result after lymph node sampling by Endobronchial Ultrasound (EBUS) is not enough to rule out mediastinal lymph node involve- ment, demanding a cervical mediastinoscopy to vouch for the results. METHODS AND OBJECTIVES: In order to study the percentage of lymph node surgical upstaging in patients with neg- ative mediastinal node staging by EBUS and evaluate the role of mediastinoscopy in these patients, we conducted a search in our department's database using the key-word EBUS in the period concerned between January 2014 and August 2020. A total of 302 patients were found. After applying defined criteria, we obtained 42 cases. RESULTS: Lymph node surgical upstaging occurred in 11 (26%) patients, of which 8 were upstaged to N2 and 3 to N1. Most of the cases were single station. Only in 5 (12% of the total) of the 11 patients, the upstaging was related to lymph node stations previously sampled by EBUS. Upstaging was more frequent among males and lower lobe tumours. DISCUSSION AND CONCLUSIONS: Regarding the 8 upstage cases for N2, 5 were single station. Of these 8 cases, only 5 would be approachable by cervical mediastinoscopy. Furthermore, 2 of them were single station, eligible for upfront surgery. Then, only in 3 (7%) of the 42 cases cervical mediastinoscopy would be of foremost importance.

Recurrent stress fractures rarely affect the same athlete. We present the case of a female triathlete who suffered multiple stress fractures in both tibias, the right fibula, and the left femoral neck. Conservative treatment was instituted in all episodes, with rest, reduced training load, and physical therapy rehabilitation. The relative energy deficiency in sport syndrome, along with an eating disorder, training overload, and osteopenia, was identified as a risk factor. Although rare, multiple stress fractures can occur in female triathletes. These patients must be screened for risk factors associated with biomechanics, nutrition, and training to develop an effective prevention and treatment program.

Resumo Fraturas por estresse recorrentes num mesmo atleta são raras. Apresentamos o caso de uma triatleta que sofreu múltiplas fraturas por estresse na tíbia bilateral, na fíbula direita e no colo femoral esquerdo. O tratamento conservador foi instituído em todos os episódios, com repouso, redução da carga de treino e reabilitação fisioterápica. Foi identificada como fator de risco a síndrome da deficiência energética relativa no esporte, com distúrbio alimentar, sobrecarga de treino e osteopenia. Mesmo que seja raro, múltiplas fraturas por estresse podem ocorrer em mulheres triatletas, nas quais é importante avaliar os fatores de risco associados à biomecânica, nutrição e ao treinamento para arquitetar um programa de prevenção e tratamento efetivos.

Male, 71 years old, active smoker. Referred to our outpatient clinic due to right upper lobe nodule with 4 year follow-up, which increased in size and metabolic uptake during the last year. CT scan also revealed multiple pleural plaques with a diffuse pattern. The patient underwent a right upper VATS lobectomy and mediastinal lymphadenectomy after intraoperative pathology consultation was positive for malignancy. Intraoperative with evidence of multiple hyline pleural plaques and aberrant neoformative lesions, mimicking teeth, on the diaphragm and parietal costal pleura, probably related to asbestos exposure.

INTRODUCTION: 55 years old, male patient. History of heavy smoking (65 UMA) and COPD. Admitted to hospital due to a left pneumonia. Thoracic CT and PET-Scan, showed left lower lobe mass measuring 92x89 mm (SUVmax 49). Several mediastinal node groups presented increased uptake of FDG. A fiberoptic bronchoscopy was performed. Citology of the bronchoalveolar lavage suggested a squamous carcinoma. EBUS of node stations 4R, 4L e 7 without evidence of malignancy. METHODS: The case was taken to a multidisciplinary meeting staged as IIIA (T3N2M0). Neoadjuvant therapy (four cycles cysplatine and gemcitabine) was decided based on station 5, suspected disease. A left lower lobectomy was performed after a cervical mediastinoscopy excluded metastasis of node stations 4R and 4L. Histology of the specimen was compatible with inflammatory myofibroblastic tumor (IMT). No lymph node involvement was reported. It was restaged as IIB (ypT3N0M0). RESULTS: Three months after surgery one de novo nodule in the lingula with 12,7 of SUVmax was reported. The nodule was removed confirming a IMT metastasis. Four months after the nodule ressection a CT showed new lung and liver nodules. A total oclusion of the left main bronchus was documented and bronchoscopic debulking of the endobronchial mass again revealed IMT. Paliative radiotherapy was decided in the multidisciplinar group targeting the left main bronchus (five sessions of radiotherapy on a dose of 20Gy in 4Gy daily fractions). Ten months after surgery due to the onset of back pain, a CT revealed a sacrum lesion whose needle biopsy was suspicious for multiple myeloma. The patient was referred to another oncological center where previous non-surgical cases had been sent in the past. The patient is now proposed for histology reassessment and discussion by the hematology and pneumology medical teams. CONCLUSION: Inflammatory myofibrobastic tumors are considered benign or low-grade malignant tumors. The size of the tumour (cut-off of 3 cm) and secure surgical resection with free margins are the major determinants for recurrence and survival. There are some cases reported in the literature of distant metastasis and sarcomatous transformation after multiple recurrences. In our patient, the lesion was bigger than 3 cm and he underwent a complete resection. Nothing could foresee this aggressive metastatic behavior, especially when the recurrence did not show a sarcomatous transformation.

RESUMO
OBJECTIVE: To investigate the prevalence and combinations of PCL injuries and their correlations with the mechanism, the occurrence of evident dislocation and associated fracture. METHOD: A retrospective study of 85 lesions of PCL operated between 2003 and 2010. Diagnosis by physical examination and dynamic radiography, compared with surgical findings. RESULTS: Injuries involving the PCL were more prevalent in men (78.8%) with a mean age of 33 years. The main cause was traffic accidents (73.80%), and (49.4%) motorcycle. Isolated PCL injury occurred in (15.3%) cases, and combined (84.7%). Among the isolated lesions, bone avulsions were nine (10.6%). The most associated PCL injuries were the ACL (48.2%), followed by LCL PCL/PLC (22.4%). Fractures were more associated with combining PCL + LCL/PLC injuries and did not appear in the PCL + MCL/PMC. Complications beyond fractures: peripheral nerve injury (4.8%) and vascular (1.2%). Evident dislocation in primary care (16.7%) was more prevalent in combined ACL + PCL + MCL/PMC (44.4%). Half the patients were operated during the acute phase. There was a statistically significant difference (p < 0.05) comparing each combination of ligament injuries with the presence of fracture, dislocation or clear mechanism of injury. CONCLUSION: Surgical treatment of PCL injuries in a center for orthopedic trauma care was mostly multiligament and mainly involving the ACL. A significant association was seen between the type of injury with mechanism of injury, presentation of the knee, if dislocated or reduced, and the presence of associated fracture. .
OBJETIVO: Pesquisar a prevalência das lesões do ligamento cruzado posterior (LCP) e suas combinações e correlações com o mecanismo e a ocorrência de luxação evidente e fratura associada. MÉTODO: Estudo retrospectivo de 85 lesões do LCP operadas entre 2003 e 2010. Diagnóstico por meio do exame físico e da radiografia dinâmica, confrontados com achados cirúrgicos. RESULTADOS: Lesões que envolveram o LCP foram mais prevalentes nos homens (78,8%) com média de idade de 33 anos. A causa principal foi o acidente de trânsito (73,80%), dos quais 49,4% de motocicleta. Lesão isolada do LCP ocorreu em 15,3% dos casos e combinada em 84,7%. Dentre as lesões isoladas, nove foram avulsões ósseas (10,6%). O ligamento mais associado às lesões do LCP foi o cruzado anterior (48,2%), seguido da lesão combinada do LCP com o ligamento colateral lateral/canto póstero-lateral (22,4%). Fraturas estiveram mais associadas à combinação LCP + LCL/CPL e não apareceram nas lesões do LCP + ligamento colateral medial/canto póstero-medial. Complicações além de fraturas: lesão de nervo periférico (4,8%) e vascular (1,2%). Luxação evidente no primeiro atendimento (16,7%), mais prevalente na combinação LCP + LCA + LCM/CPM (44,4%). Metade dos pacientes foi operada na fase aguda. Houve diferença estatística significativa (p < 0,05) na comparação de cada combinação de lesões de ligamentos com a presença de fratura, luxação evidente ou mecanismo do trauma.

RESUMO
OBJECTIVE: To evaluate the impact of intraoperative transesophageal echocardiography (TEE) on surgical decisions patients undergoing cardiac surger in a Portuguese hospital. METHODS: The authors retrospectively analyzed a series of 850 examinations performed between 2003 and 2009 in patients who underwent different cardiac surgical procedures. Medical records and TEE reports were reviewed to determine whether new information was found and whether this changed the surgical plan. RESULTS: Intraoperative TEE revealed new information in 32% of the study population and had surgical impact in 29% of all patients. TEE had the greatest impact in class I indications, but its use in class II indications also had a significant impact. No cases of morbidity or mortality were found. CONCLUSIONS: Our findings suggest that intraoperative TEE should be used routinely in all patients undergoing cardiac surgery.
