    The patient was a 53-year-old female who presented with a primary complaint of reddening of the left precordial skin. She had undergone mastectomy for cancer of the left breast 12 years and 4 months earlier and had received endocrine chemotherapy including TAM as a postoperative adjuvant therapy. A diagnosis of thoracic wall recurrence was made by chest CT and pathological examination of skin biopsy specimens. Toremifene (TOR) was administrated at 120 mg/day, and PR was maintained for 8 months. Even after the condition became PD, the patient has retained adequate QOL with combination therapies including radiotherapy, and is still treated on an outpatient basis 3 years after the beginning of the treatment.

    Full Text Available Introduction: Surgical treatment of malignant thoracic wall tumors represents a formidable challenge. In particular, locally advanced tumors that have already infiltrated critical anatomic structures are associated with a high surgical morbidity and can result in full thickness defects of the thoracic wall. Plastic surgery can reduce this surgical morbidity by reconstructing the thoracic wall through various tissue transfer techniques. Sufficient soft tissue reconstruction of the thoracic wall improves life quality and mitigates functional impairment after extensive resection. The aim of this article is to illustrate the various plastic surgery treatment options in the multimodal therapy of patients with malignant thoracic wall tumors.Material und methods: This article is based on a review of the current literature and the evaluation of a patient database.Results: Several plastic surgical treatment options can be implemented in the curative and palliative therapy of patients with malignant solid tumors of the chest wall. Large soft tissue defects after tumor resection can be covered by local, pedicled or free flaps. In cases of large full-thickness defects, flaps can be combined with polypropylene mesh to improve chest wall stability and to maintain pulmonary function. The success of modern medicine has resulted in an increasing number of patients with prolonged survival suffering from locally advanced tumors that can be painful, malodorous or prone to bleeding. Resection of these tumors followed by thoracic wall reconstruction with viable tissue can substantially enhance the life quality of these patients. Discussion: In curative treatment regimens, chest wall reconstruction enables complete resection of locally advanced tumors and subsequent adjuvant radiotherapy. In palliative disease treatment, stadium plastic surgical techniques of thoracic wall reconstruction provide palliation of tumor-associated morbidity and can therefore improve

    The most common causes of major thoracic traumas are stabwounds, traffic accidents and gunshot wounds. Thoracic wall defects developing due to these injuries should be repaired if they lead to paradoxal respiration. We repaired the thoracic wall defect of the 25-year-old male patient who was admitted to our clinic with gunshot wound with Polytetrafluoroethylene graft as expansion dysfunction and paradoxal respiration developed. No complications developed and he was discharged with recovery.  In conclusion, Polytetrafluoroethylene graft is a good reconstruction tool at present because it prevents paradoxal respiration successfully, applied easily and cosmetic.

    The Askin tumours is an extremely rare and malignant process in the thoracic pulmonary region during infancy and youth. The differential diagnosis has to be considered with other thoracic wall tumours that are more common in pediatrics like the undifferentiated neuroblastoma, the embionic rabdomiosarcoma, the Ewing sarcoma and the linfoma. A retrospective examination was carried out on 473 thoracic wall tumours from 1994 to 1997 at our centre, resulting in 4 patients with an anatomopathologically tested Askin tumour (ages from 13-21). All the cases were studied using simple radiography and CT. In two cases MRI was also used. The most common clinical manifestation was a palpable painful mass in the thoracic wall. In the simple radiograph the main finding was a large mass of extrapleural soft material, with costal destruction ( n=3) and a pleural effusion (n=2). In the CT study the mass was heterogeneous, with internal calcifications in one case. CT and MRI showed invasion in the mediastinum (n=1), medular channel (n=1) and phrenic and sulphrenic extension (n=1). The Askin tumour should be included in the differential diagnosis of thoracic wall masses in infant-youth ages. There are no specific morphological characteristics. Both CT and MRI are useful for the diagnosis, staging and follow up. (Author) 11 refs

    Ewing's sarcomas in the chest wall have in common the facts that the ribs are mainly changed asteolytically; sclerosing is initially seen very seldom, it usually occurs after the therapy; and periosteal detachment with stratification or spicula formation was not observed. All our children had considerably larger intrathoracic tumors than tumors palpable at the chest wall and a notably low number of symptoms in regard of the partially gigantic tumors. (orig.) [de

    Childhood malignant chest wall tumors may require extensive surgical resection and reconstruction with musculoskeletal flaps or non-resorbable prosthetic materials. Implant-related complications and scoliosis often occur. This study analyzes the outcomes of chest wall reconstruction using resorbable plates as an alternative approach. Retrospective review (2007-2015) of patients who underwent resection of malignant primary chest wall tumors in 2 tertiary pediatric centers. Reconstruction was performed using copolymer (l-lactic and glycolic acid) plates, fixed to the ribs and surrounding structures with copolymer screws and/or polyglactin sutures. Eight patients aged 10.6+2.6years were treated. There were no operative complications, and implant removal was not required in any case. Six patients received postoperative radiotherapy. Over follow-up (39.6months, range 9.4-78), chest wall shape was maintained in all, and there were no radiological artifacts. Three patients developed scoliosis (Cobb 17°-33°), but treatment was needed only in one, who had undergone hemivertebrectomy. There were no cases of local tumor relapse. One patient died because of metastatic spread. Implantation of bioabsorbable l-lactic and glycolic acid copolymer plates with a relatively simple technique provided a rigid, stable reconstruction with only mild mid-/long-term complications. Resorbable plates may be a good alternative for pediatric chest wall reconstruction. IV. Copyright © 2016 Elsevier Inc. All rights reserved.

    Soft tissue sarcoma (STS) of the chest wall is uncommon, and our knowledge is limited to small, single institutional case series. Although some series have examined prognostic factors for survival with this rare set of neoplasms, our knowledge of the patterns of relapse is limited. We performed a retrospective review of a prospectively maintained database of consecutive patients treated for STS of the chest wall. Predictors of survival and recurrence were analyzed using Cox and competing-risk regression analyses. From 1989 to 2011, 192 patients underwent resection for STS of the chest wall. The most common histopathologic type was desmoid (33 [17%]), followed by undifferentiated pleomorphic sarcoma (32 [16%]), liposarcoma (22 [11%]), and myxofibrosarcoma (22 [11%]). The median follow-up was 50.9 months. The 5- and 10-year survival rates were 73% and 61%, respectively. Recurrences occurred in 45 patients (23%): 17 developed local recurrences, and 28 developed distant recurrences. Among the patients who developed recurrences, the median time to event was 11.6 months for local recurrences and 13.5 months for distant recurrences. The most common histologic type among recurrences was undifferentiated pleomorphic sarcoma (n = 12), and the most common site of distant recurrences was lung (n = 18). The primary treatment modality for both local and distant recurrences was surgical resection; median survival after recurrence was 19.4 months. Recurrences of STS are common after surgical resection. Although local or distant recurrences can occur soon after surgery, both can often be treated with resection, producing reasonable outcomes. Copyright © 2013 The Society of Thoracic Surgeons.

    Several models of ballistic blunt thoracic trauma are available, including human cadavers and large animals. Each model has advantages and disadvantages regarding anatomy and physiology, but they have not been compared with identical ballistic aggression. To compare thoracic wall behavior in 40-kg pigs and human cadavers, the thorax of 12 human cadavers and 19 anesthetized pigs were impacted with two different projectiles at different speeds. On the thoracic wall, the peak acceleration, peak velocity, maximal compression, viscous criterion, and injury criteria (e.g. abbreviated injury scale and number of rib fractures) were recorded. The correlations between these motion and injury parameters and the blunt criterion were compared between the two groups. The bone mineral density of each subject was also measured. The peak acceleration, the peak velocity and the viscous criterion were significantly higher for the pigs. The AIS and the number of rib fractures were significantly higher for human cadavers. The bone mineral density was significantly higher for cadavers, but was, for the two groups, significantly lower than for 30-year-old human. The motion of the pig's thoracic wall is greater than that of the human cadaver, and the severity of the impact is always greater for human cadavers than for pigs. In addition, pig bone is more elastic and less brittle than older human cadaver bone. Due to the bone mineral density, the thoracic wall of human adults should be more rigid and more resistant than the thoracic wall of human cadavers or pigs. Copyright © 2012 Elsevier Ireland Ltd.

    Symptomatic thoracic disc herniation is clinically rare. There are few cases of disc herniation of the thoracic spine in top athletes described in the literature. We herein present a rare case of chest wall pain due to thoracic disc herniation in a professional baseball pitcher. A 30-year-old, left-handed pitcher complained of left-sided chest wall pain in the region of his lower ribs during a game. Neurological examination revealed hypoesthesia of the left side of the chest at the level of the lower thoracic spine. Magnetic resonance imaging (MRI) of the thoracic spine showed a left-sided paramedian disc herniation at the T9-T10 level. The player was initially prescribed rest, administration of pregabalin (150 mg twice a day), and subsequent physical rehabilitation. He was able to resume full training and pitching without medication 6 months after the onset. A follow-up MRI of the thoracic spine showed a reduction in the size of the herniated disc compared to the initial findings. Though relatively rare, thoracic disc herniation should be considered in cases of chest wall pain in athletes.

    Sarcomas of the chest wall are rare, and wide surgical resection is generally the cornerstone of treatment. The objective of our study was to evaluate outcome of full-thickness resections of recurrent and primary chest wall sarcomas. To evaluate morbidity, mortality, and overall and disease-free survival after surgical resection of primary and recurrent chest wall sarcomas, we performed a retrospective review of all patients with sarcomas of the chest wall surgically treated at two tertiary oncologic referral centers between January 1980 and December 2006. Patient, tumor, and treatment characteristics, as well as the follow-up of these patients, were retrieved from the patients' original records. One hundred twenty-seven patients were included in this study, 83 patients with a primary sarcoma and 44 patients with a recurrence. Age, sex, tumor size, histologic type, grade and localization on the chest wall were similar for both groups. Fewer neoadjuvant and adjuvant therapies were used in the treatment of recurrences. Chest wall resection was more extensive in the recurrent group, which did not result in more complications (23%) or more reinterventions (5%). Microscopically radical resection was achieved in 80% of the primary sarcomas and 64% of the recurrences. With a median follow-up of 73 months, disease-free survival after surgery for recurrences was 18 months versus 36 months for primary sarcomas, with 5-year survival rates of 50% and 63%, respectively. Although chances for local control are lower after surgical treatment of recurrent chest wall sarcoma, chest wall resection is a safe and effective procedure, with an acceptable survival.

    A 12-year-old fox-terrier dog presented with forelimb lameness of 3-weeks duration. Ultrasonography revealed a mass within the thoracic wall and osteolysis of the left third rib. A squamous cell carcinoma was diagnosed by cytological examination of an ultrasound-guided fine needle aspirate of this mass. As a result of the diagnosis of neoplasia, the dog was euthanatized. Necropsy revealed a solitary expansile mass within the left cranial lung lobe, and a mass within the adjacent thoracic wall. Thickening of the pleura between the two masses was visible, although adhesions were not present. Histology of both masses revealed a well-differentiated squamous cell carcinoma. To the authors' knowledge, this is the first detailed description of direct invasion of the thoracic wall by a canine lung tumour.

    Purpose: To investigate the characteristics of plaque in the thoracic aorta using three dimensional multicontrast magnetic resonance imaging. Materials and methods: Elderly subjects (≥60 years) were recruited in this study. Thoracic aorta was imaged on a 3.0T MR scanner by acquiring multicontrast sequences. The plaque burden was evaluated by measuring lumen area, wall area, wall thickness, and normalized wall index. The presence or absence of plaque and intraplaque hemorrhage (IPH)/mural thrombus (MT) were identified. The characteristics of atherosclerosis among different thoracic aorta segments (AAO: ascending aorta; AOA: aortic arch, and DOA: descending aorta) were determined. Results: Of 66 recruited subjects (mean age 72.3 ± 6.2 years, 30 males), 55 (83.3%) had plaques in the thoracic aorta. The prevalence of plaque in AAO, AOA, and DAO was 5.4%, 72.7%, and 71.2%, respectively. In addition, 21.2% of subjects were found to have lesions with IPH/MT in the thoracic aorta. The prevalence of IPH/MT in segment of AAO, AOA and DAO was 0%, 13.6%, and 12.1%, respectively. The aortic wall showed the highest NWI in DAO (34.1% ± 4.8%), followed by AOA (31.2% ± 5%), and AAO (26.8% ± 3.3%) (p < 0.001). Conclusion: Three dimensional multicontrast MR imaging is capable of characterizing atherosclerotic plaques in the thoracic aorta. The findings of high prevalence of plaques and the presence of high risk plaques in the thoracic aorta suggest early screening for aortic vulnerable lesions in the elderly.

    We present a case of recurrent primary synovial sarcoma of the chest wall in a 55-year-old man. Imaging at the time of recurrence revealed extensive involvement of the left pleural cavity by the tumor. The patient developed severe congestive heart failure with restrictive/constrictive physiology and subsequently died in the hospital 5 months after initial presentation. At autopsy, the tumor encased the entire left lung in a rind-like fashion and diffusely involved the pericardium. Recurrent synovial sarcoma was confirmed by histological examination. Synovial sarcoma should be considered in the differential diagnosis of chest masses, especially in young or middle-aged adults.

    Despite progress in reconstructive techniques, rebuilding portions of the thorax remains challenging, in particular when large resections, contamination or infection are involved. No other cases of thoracic reconstruction in trauma patients with biological prosthesis have been described since now. We report a case of thoracic reconstruction in highly infected field in a trauma patient. We also performed a literature review about the topic. Collamend® demonstrated its usefulness in thoracic wall reconstruction even in trauma patients and infected fields.

    The purpose of this study is to verify the usefulness of the quantification of aortic wall involvement by enhanced computed tomography (CT). One-hundred thirteen Japanese patients underwent two enhanced CT of the descending thoracic aorta at intervals. We sliced the descending thoracic aorta continuously from the level of the tracheal bifurcation with 1 cm intervals, and we defined aortic wall volume (AWV) (cm 3 ) as the sum of a 7-slice area of aortic wall involving calcification. The average of AWV increased from 7.95±2.92 cm 3 to 8.70±2.98 cm 3 . The developmental rate of AWV (ΔAWV) was 0.270±0.281 cm 3 /year. ΔAWV did not have a significant correlation with any risk factor at the baseline. ΔAWV had significant correlation with total cholesterol, (LDL-C) low-density lipoprotein cholesterol and LDL-C/(HDL-C) high-density lipoprotein cholesterol ratio at the follow-up, and by multivariate analysis with only the LDL-C/HDL-C ratio. ΔAWV was not correlated with the intake status of hypoglycemic, antihypertensive or lipid-lowering drugs. The cut-off level of total cholesterol with the most significant odds ratio for progression of aortic wall was 190 mg/dl, and that of LDL-C was 130 mg/dl. This method proved to be useful for the non-invasive assessment of aortic wall thickness. (author)

    Aortic valve disease increases velocity and changes the way blood enters the aorta. Over time, the biomechanical environment can cause aortic remodelling. We hypothesized that aortic geometry and wall stress would be different in patients with aortic valve disease compared with controls. We examined 40 patients with aortic sclerosis (n = 10) or mild (n = 10), moderate (n = 10), and severe (n = 10) aortic stenosis, and also 10 control individuals. The thoracic aorta of each individual was reconstructed into a three-dimensional model from computed tomography. We measured geometric variables and used finite element analysis to compute aortic wall stress. Statistical analyses were performed to test our hypothesis. Aortic wall stress was significantly associated with tortuosity of the descending aorta (r = 0.35, p = 0.01), arch radius (r = 0.49, p < 0.01), ascending aortic diameter (r = 0.59, p < 0.01), and aortic centerline length (r = 0.39, p < 0.01). Wall stress was highest in patients with severe stenosis (p = 0.02), although elevations in wall stress were also noted in those with mild stenosis (p = 0.02), and aortic sclerosis (p = 0.02) compared with controls. Similar trends were observed when we corrected for difference in blood pressure. Total centerline tortuosity was higher in patients with severe aortic stenosis than in controls (p = 0.04), as was descending aorta tortuosity (p = 0.04). Aortic geometry is associated with aortic wall stress. Patients with aortic valve disease have higher aortic wall stress than controls, and those with severe aortic stenosis have more tortuous aortas. However, increases in geometric measures and wall stress are not stepwise with increasing disease severity. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    Surgical intervention for neurogenic thoracic outlet syndrome (NTOS) is not always successful. Treatment plans can be difficult in patients presenting with recurrent symptoms. The purpose of this study was to evaluate outcomes of this patient subset, who underwent operative intervention to remove a remaining or residual first rib because of recurrent thoracic outlet syndrome (TOS)-related symptoms. Data on 15 patients who presented with previous scalenectomy, brachial plexus lysis, or first rib resection and scalenectomy (FRRS) with residual rib present on chest radiograph from 2004 to 2012 were retrospectively reviewed from a prospectively maintained database, with approval from the Institutional Review Board of Johns Hopkins Hospital. Patients were classified as having a remaining first rib if they presented with recurrent NTOS symptoms, had previously undergone scalenectomy and/or brachial plexus lysis alone to decompress the thoracic outlet, and exhibited an intact first rib on chest X-ray, whereas patients were classified as having a remnant rib if they presented with recurrent symptoms of NTOS, had previously undergone a first rib resection at another institution, and exhibited an anterior or posterior first rib on chest X-ray. Demographic and clinical characteristics along with postoperative outcomes were evaluated. Different precipitating events reaggravated symptoms in 12 patients. Events included car accidents (n = 4), work-related repetitive movements (n = 5), lifting heavy objects (n = 2), and repetitive injury (n = 1). Group 1: Previous scalenectomy (n = 2), brachial plexus lysis alone (n = 2), or both (n = 3). Seven patients (2 men and 5 women; mean age 34 [25-53]) presented with NTOS symptoms due to a remaining first rib at an average of 24 months (range: 2-68) after their initial operation at another institution. All underwent transaxillary first rib resection, residual scalene resection, and lysis of scar tissue. Perioperative complications

    Postoperative pneumonia continues to be a leading cause of mortality and morbidity after thoracic surgery. High-frequency chest-wall compression (HFCWC) is an established therapeutic adjunct for patients with chronic pulmonary disorders that impair bronchopulmonary secretion clearance. We studied the feasibility of applying HFCWC following thoracic surgery. Twenty-five consecutive adult patients who underwent a variety of thoracic operations received at least one HFCWC treatment in the first 2 postoperative days, along with routine postoperative care. HFCWC was applied at 12 Hz, for 10 min. Routine hemodynamic and pulse oximetry data were collected before, during, and after HFCWC. We also collected qualitative data on patient tolerance and preference for HFCWC versus percussive chest physiotherapy. No major adverse events were encountered. Hemodynamic and pulse oximetry values remained stable before, during, and after HFCWC. Eighty-four percent of the subjects reported little or no discomfort during therapy, and the subjects who expressed a preference preferred HFCWC to conventional chest physiotherapy by more than two to one. HFCWC is a safe, well-tolerated adjunct after thoracic surgery. The observation of hemodynamic stability is especially important, considering that the patients were studied in the early postoperative period, during epidural analgesia.

    Repair of fusiform descending thoracic aortic aneurysms (DTAs) is indicated when aneurysmal diameter exceeds a certain threshold; however, diameter-related indications for repair of saccular DTA are less well established. Human subjects with fusiform (n = 17) and saccular (n = 17) DTAs who underwent computed tomographic angiography were identified. Patients with aneurysms related to connective tissue disease were excluded. The thoracic aorta was segmented, reconstructed, and triangulated to create a mesh. Finite element analysis was performed using a pressure load of 120 mm Hg and a uniform aortic wall thickness of 3.2 mm to compare the pressure-induced wall stress of fusiform and saccular DTAs. The mean maximum diameter of the fusiform DTAs (6.0 ± 1.5 cm) was significantly greater (p = 0.006) than that of the saccular DTAs (4.4 ± 1.8 cm). However, mean peak wall stress of the fusiform DTAs (0.33 ± 0.15 MPa) was equivalent to that of the saccular DTAs (0.30 ± 0.14 MPa), as found by using an equivalence threshold of 0.15 MPa. The mean normalized wall stress (peak wall stress divided by maximum aneurysm radius) of the saccular DTAs was greater than that of the fusiform DTAs (0.16 ± 0.09 MPa/cm vs. 0.11 ± 0.03 MPa/cm, p = 0.035). The normalized wall stress for saccular DTA is greater than that for fusiform DTA, indicating that geometric factors such as aneurysm shape influence wall stress. These results suggest that saccular aneurysms may be more prone to rupture than fusiform aneurysms of similar diameter, provide a theoretical rationale for the repair of saccular DTAs at a smaller diameter, and suggest investigation of the role of biomechanical modeling in surgical decision making is warranted.

    The Askin tumours is an extremely rare and malignant process in the thoracic pulmonary region during infancy and youth. The differential diagnosis has to be considered with other thoracic wall tumours that are more common in pediatrics like the undifferentiated neuroblastoma, the embionic rabdomiosarcoma, the Ewing sarcoma and the linfoma. A retrospective examination was carried out on 473 thoracic wall tumours from 1994 to 1997 at our centre, resulting in 4 patients with an anatomopathologically tested Askin tumour (ages from 13-21). All the cases were studied using simple radiography and CT. In two cases MRI was also used. The most common clinical manifestation was a palpable painful mass in the thoracic wall. In the simple radiograph the main finding was a large mass of extrapleural soft material, with costal destruction ( n=3) and a pleural effusion (n=2). In the CT study the mass was heterogeneous, with internal calcifications in one case. CT and MRI showed invasion in the mediastinum (n=1), medular channel (n=1) and phrenic and sulphrenic extension (n=1). The Askin tumour should be included in the differential diagnosis of thoracic wall masses in infant-youth ages. There are no specific morphological characteristics. Both CT and MRI are useful for the diagnosis, staging and follow up. (Author) 11 refs.

    Phyllodes tumour of the breast is a relatively uncommon condition, and rarely invades the chest wall. We report a case of young women who had recurrent large phyllodes tumour invading the chest wall, following mastectomy, chemotherapy and radiotherapy. A multidisciplinary approach was used for radical resection of the tumour, chest wall and reconstruction.

    The aim of this randomized, parallel-arm, open-label trial was to compare lumbar versus thoracic epidural morphine for severe isolated blunt chest wall injury as regards the incidence of pulmonary complications and pain control. Fifty-five patients who sustained severe isolated blunt chest wall trauma were randomized using a computer-generated list to receive epidural morphine injection every 24 h through an epidural catheter inserted into the lumbar (n = 28) or thoracic (n = 27) region. Need for mechanical ventilation, incidence of pneumonia, arterial blood gas values, and pulmonary function tests were compared in both groups. Pain scores, supplemental analgesic consumption, length of intensive care unit (ICU) stay, and occurrence of epidural morphine-related side effects were compared as well. Primary outcome measures were need for mechanical ventilation and incidence of pneumonia. Five (17.9 %) patients in the lumbar group were mechanically ventilated, compared with six (22.2 %) in the thoracic group (hazard ratio 1.35; 95 % CI 0.41-4.4; P = 0.611). Seven (25 %) patients in the lumbar group developed pneumonia versus six (22.2 %) in the thoracic group (hazard ratio 0.97; 95 % CI 0.33-2.9; P = 0.96). Both groups were comparable as regards the duration of mechanical ventilation (P = 0.141) and length of ICU stay (P = 0.227). Pain scores, supplemental analgesic consumption, pulmonary function, and occurrence of epidural morphine-related side effects were, likewise, comparable (P > 0.05). Lumbar and thoracic epidural morphine administered as once-daily injection to patients with severe isolated blunt chest wall trauma were comparable in terms of pain control, incidence of pulmonary complications, and occurrence of epidural morphine-related side effects.

    Synthetic materials have traditionally been used for tissue reconstruction in thoracic surgery. New biomaterials have been tested in other areas of surgery with good results. Non-cross-linked swine dermal collagen prosthesis has been used to reconstruct musculofascial defects in the trunk with low infection and herniation rate. Retrospectively, we analyze our initial experience of chest wall reconstruction on large defects using a non-cross-linked swine dermal collagen matrix mesh with a thickness of 1.4 mm. A total of 11 consecutive patients were included. Preoperative, intraoperative, and postoperative data were taken into consideration. Eleven sarcoma patients with a mean age of 58.25 ± 12.9 years underwent chest wall resections. Complete thoracic wall defects ranged from 6 · 9 to 16 · 25 cm in size. In all cases, we used a porcine collagen matrix mesh, and in all patients, it was covered by transposition of myocutaneous flap. The complications occurred in 5 (45%) patients, 1 (9%) pneumonia, 1 atrial fibrillation (9%), and 3 (27%) wound healing difficulty because of hematoma or infection. There was no respiratory impairment, and the pulmonary function (total lung capacity, vital capacity, and forced expiratory volume in 1 second) was not statistically different before and after surgery. The 30-day mortality was 0%, 1-year mortality and 2-year mortality was 27.2%. The collagen material resulted in a durable and good to excellent chest wall stability in clinical follow-ups, and on computer tomography scans spanning over 2 years. Non-cross-linked acellular porcine dermal collagen matrix is a feasible and reliable biological patch material for reconstruction of the thoracic wall. Excellent wound healing, long-term stability, low complication, and good pulmonary function are achieved even in large defects.

    Irradiation of the thoracic wall with high-speed electrons is one of the standard methods of prophylaxis and therapy of local recurrences and cutaneous metastases of an operated mammary carcinoma. The surface dose, however, is only 85% of the maximum dose, due to the depth dose curve of the electron beams with the preponderantly applied energy of 7 MeV. This is a poor value, since most of all recurrences appear near to the surface and so the risk of giving an insufficient dosis is involved. The dose distribution could be essentially improved by the use of moulages on the chest. The moulages were made of different materials which were tested and compared with respect to their suitability for radiotherapeutic purposes. The best materials proved to be 'Urgo-Plastan' (manufacturer: Holphar, Sulzbach) and 'Orthoplast' (manufacturer: Johnson and Johnson, Duesseldorf). Both materials are synthetic substances which after heating can easily be adapted to the body shape and which offer a good stability, little inconvenience for the patient and a relative easy handling. With these moulage materials, the surface dose is increased to 98% ('Urgo-Plastan') and 99% ('Orthoplast') of the maximum dose. (orig.) [de

    Full Text Available Thoracic Aortic Aneurysms and Dissections (TAAD are a major cause of death in the United States. The spectrum of TAAD ranges from genetic disorders, such as Marfan syndrome, to sporadic isolated disease of unknown cause. We hypothesized that genomic copy number variants (CNVs contribute causally to early onset TAAD (ETAAD. We conducted a genome-wide SNP array analysis of ETAAD patients of European descent who were enrolled in the National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC. Genotyping was performed on the Illumina Omni-Express platform, using PennCNV, Nexus and CNVPartition for CNV detection. ETAAD patients (n = 108, 100% European American, 28% female, average age 20 years, 55% with bicuspid aortic valves were compared to 7013 dbGAP controls without a history of vascular disease using downsampled Omni 2.5 data. For comparison, 805 sporadic TAAD patients with late onset aortic disease (STAAD cohort and 192 affected probands from families with at least two affected relatives (FTAAD cohort from our institution were screened for additional CNVs at these loci with SNP arrays. We identified 47 recurrent CNV regions in the ETAAD, FTAAD and STAAD groups that were absent or extremely rare in controls. Nine rare CNVs that were either very large (>1 Mb or shared by ETAAD and STAAD or FTAAD patients were also identified. Four rare CNVs involved genes that cause arterial aneurysms when mutated. The largest and most prevalent of the recurrent CNVs were at Xq28 (two duplications and two deletions and 17q25.1 (three duplications. The percentage of individuals harboring rare CNVs was significantly greater in the ETAAD cohort (32% than in the FTAAD (23% or STAAD (17% cohorts. We identified multiple loci affected by rare CNVs in one-third of ETAAD patients, confirming the genetic heterogeneity of TAAD. Alterations of candidate genes at these loci may contribute to the pathogenesis of TAAD.

    Biologic mesh is commonly used in abdominal wall reconstruction but may result in increased hernia recurrence. There are minimal data on repair of these recurrent hernias. We conducted a retrospective chart review of 24 patients presenting to a single surgeon with recurrent ventral hernia, previously repaired with biologic mesh. Seventeen of 24 study patients underwent open repair, including 5 revisions of incomplete external oblique release. Mesh was polypropylene in 11 patients and fenestrated condensed polytetrafluoroethylene in 3 patients. In 1 patient, no mesh was used. In 2 patients, bridged biologic mesh was used because of risk of exposure. All biologic repairs have since recurred. Complications occurred in 3 of 15 prosthetic mesh patients and in all biologic mesh patients. Prior components release can be repeated if computed tomography scan reveals incomplete release. Recurrence is common after bridged biologic mesh repair. Conventional mesh can be used safely in many recurrent abdominal hernias after biologic mesh failure. Copyright © 2014 Elsevier Inc.

    Extrinsic airway compression due to chest wall deformity is not commonly observed. Although this condition can be diagnosed more easily with the help of multidetector CT, the standard treatment method has not yet been definitely established. We report a case of an eighteen-year-old male who suffered from severe extrinsic tracheal compression due to scoliosis and straightening of the thoracic spine, confirmed on CT and bronchoscopy. The patient underwent successful placement of tracheal stent but later died of bleeding from the tracheostomy site probably due to tracheo-brachiocephalic artery fistula. We describe the CT and bronchoscopic findings of extrinsic airway compression due to chest wall deformity as well as the optimal treatment method, and discuss the possible explanation for bleeding in the patient along with review of the literature.

    Chest wall deformities/defects and chest wall resections, as well as complex rib fractures require reconstruction with various prosthetic materials to ensure the basic functions of the chest wall. Titanium provides many features that make it an ideal material for this surgery. The aim is to present our initial results with this material in several diseases. From 2008 to 2012, 14 patients were operated on and titanium was used for reconstruction of the chest wall. A total of 7 patients had chest wall tumors, 2 with sternal resection, 4 patients with chest wall deformities/defects and 3 patients with severe rib injury due to traffic accident. The reconstruction was successful in all cases, with early extubation without detecting problems in the functionality of the chest wall at a respiratory level. Patients with chest wall tumors including sternal resections were extubated in the operating room as well as the chest wall deformities. Chest trauma cases were extubated within 24h from internal rib fixation. There were no complications related to the material used and the method of implementation. Titanium is an ideal material for reconstruction of the chest wall in several clinical situations allowing for great versatility and adaptability in different chest wall reconstructions.

    Glioblastoma multiforme (GBM) is the most common and the most malignant primary intracranial tumor in adults and it is usually occurs between the age of 40 and 60 years. It is local invasive and recurrent tumor and hence that has a poor prognosis. However, recent advances in tumor surgery, irradiation and chemotherapeutic agent permit long survival and metastasis which is symptomatic. Previously studies reported spinal metastasis, but we report a first case of synchronous symptomatic cerebellar and cervical spinal metastasis after resection of symptomatic thoracic spinal metastasis from temporal GBM without any recurrence of excision areas.

    We report on a 41-year-old woman with a chest wall desmoid tumour who was successfully treated with a computed tomography (CT)-guided steroid injection. She presented with a palpable mass in the right upper chest wall and was treated by surgical excision and postoperative radiation therapy due to recurrence of the mass at the surgical site. At 20 months after the second operation, a recurrent mass was again detected in the anterosuperior portion of the previous surgical site on CT. We performed a CT-guided steroid injection weekly for 4 weeks by applying a mixture of 3 mL of triamcinolone acetonide (40 mg/mL) and 3 mL of 1% Lidocaine, administering 4-6 mL of the mixture, to the lesion. Six months later, CT showed a marked decrease in the size of the mass.

    Low megavolt electron beam therapy was used to treat 68 women and one man with recurrent carcinoma of the breast on the chest wall. Photon irradiation had been used previously in 53 patients. Of the 63 patients who survived 2 months or longer after electron irradiation, 59 (94%) achieved a complete response. Persistent radiation ulcers developed in only 2 patients (3%). No other late radiation complications were observed. Nineteen patients (28%) survived 3 years after electron irradiation, with a median survival of 54 months. In this group, disease eventually recurred in all patients who received a calculated NSD of less than 1400 ret; no disease recurred in the patients who received doses greater than 1400 ret. It is concluded that megavolt electron irradiation is effective in the treatment of chest wall recurrence from carcinoma of the breast and is safe even in patients who have had a previous course of photon irradiation.

    Primary sarcomas of the thorax are uncommon. The purpose of this review is to describe the radiologic findings of sarcomas affecting the thorax, in particular the chest wall, pleura, and lungs. Most primary sarcomas affecting the thorax arise in the chest wall, and the most common sarcomas of the chest wall are chondrosarcoma, osteosarcoma, Ewing's sarcoma/primitive neuroectodermal tumor, malignant fibrous histiocytoma, and fibrosarcoma. Primary pleural and pulmonary sarcomas are rare. Although histologic analysis is almost always required for accurate diagnosis, imaging is important for staging of these tumors, and several of these tumors have distinctive radiologic features, allowing the radiologist to narrow the differential diagnosis.

    2017-12-01

    Studies of abdominal wall reconstruction with concurrent panniculectomy have reported contradictory results. The authors hypothesized that patients undergoing abdominal wall reconstruction with concurrent panniculectomy experience more wound healing complications but similar rates of hernia recurrence compared with abdominal wall reconstruction alone. Of 548 consecutive patients, 305 patients (55.7 percent) underwent abdominal wall reconstruction alone and 243 (44.3 percent) underwent abdominal wall reconstruction with concurrent panniculectomy. Mean follow-up was 30 months. The authors compared these two groups' postoperative complications and outcomes before and after propensity score analysis. Abdominal wall reconstruction with concurrent panniculectomy patients had a significantly higher overall complication rate (38.3 percent versus 29.2 percent; p = 0.025) and a trend toward a higher surgical-site occurrence rate (27.6 percent versus 20.7 percent; p = 0.06) compared with abdominal wall reconstruction alone. There were significantly higher incidences of skin dehiscence (19.3 percent versus 12.5 percent; p = 0.032), fat necrosis (10.7 percent versus 3.6 percent; p = 0.002), and infection abscess (9.5 percent versus 4.3 percent; p = 0.023) but no significant difference in hernia recurrence (6.9 percent versus 11.5 percent; p = 0.27) at long-term follow-up. Propensity score analysis yielded 188 pairs of matched patients with no significant differences in overall complication and hernia recurrence rates. Significantly higher rates of fat necrosis (9.6 percent versus 4.3 percent; p = 0.041) and abscess (10.1 percent versus 3.2 percent; p = 0.007) were observed in the abdominal wall reconstruction with concurrent panniculectomy group. Abdominal wall reconstruction with concurrent panniculectomy is associated with higher wound morbidity but similar surgical-site occurrence and hernia recurrence rates at long-term follow-up. The authors believe that panniculectomy can

    Purpose: Long-term outcome after radiation therapy for local-regional recurrence of breast cancer after mastectomy is generally poor. This study was performed to evaluate the long-term outcome for a potentially favorable subgroup of patients with chest wall recurrence. Methods and Materials: Of 71 patients with an isolated local-regional recurrence of breast cancer after mastectomy, 18 were identified who met the following favorable selection criteria: 1) a disease-free interval after mastectomy of 2 years or more, 2) an isolated chest wall recurrence, and 3) tumor size < 3 cm or complete excision of the recurrent disease. All 18 patients were treated with local-regional irradiation between 1967 and 1988. Radiotherapy (RT) was delivered to the chest wall to a median total dose of 60 Gy (range 30-66 Gy). Four patients received adjuvant chemotherapy and six patients received adjuvant hormonal therapy. Results: With a median follow-up of 8.4 years, nine of 18 patients were alive and free of disease. The 10-year actuarial overall and cause-specific survivals were 72% and 77%, respectively. The 10-year actuarial relapse-free survival and local control were 42% and 86%, respectively. Conclusion: Treatment for a local-regional recurrence of breast cancer after mastectomy in a favorable subgroup of patients results in a high rate of long-term survival as well as excellent local control. Aggressive treatment is warranted in this favorable subgroup of patients. 1998 Elsevier Science Inc

    To determine the features revealed by two-phase spiral CT scanning useful for differential diagnosis between recurrent cancer and benign wall thickening in patients who have undergone subtotal gastrectomy for stomach cancer. We retrospectively reviewed 25 cases in which wall thickening of more than 1cm in the remnant stomach after subtotal gastrectomy was revealed by two-phase spiral CT scanning. All cases were confirmed: 11 were recurrent cancer, and in 14, benign wall thickening was demonstrated. We analyzed the CT findings including maximal thickness of the gastric wall, patterns of wall thickening, degree of contrast enhancement seen during the arterial and portal phases, and the presence of perigastric strands. Maximal wall thickness was classified as either more or less than 15mm, and as either focal or diffuse. We also determined whether lymphadenopathy was present. Mean maximal gastric wall thickness was 18.4mm in the recurrent cancer group ({sup g}roup A{sup )} and 12.6mm in the benign group ({sup g}roup B{sup )}. The gastric wall was thicker than 15mm in 10 of 11 group A cases and in 3 of 14 in group B; wall thickening was focal (n=3) or diffuse (n=8) in group A, and focal (n=13) or diffuse (n=1) in group B, while the enhancement patterns seen during the arterial and portal phase, respectively, were high/high (n=8), low/high (n=1) and low/low (n=2) in group A, and low/low (n=7), low/high (n=4), high/low (n=1) and high/high (n=2) in group B. Perigastric strands were observed in nine cases in group A, but in none in group B, while lymphadenopathy was combined with wall thickening in seven group A cases but in none of those in group B. In patients who have undergone subtotal gastrectomy for gastric cancer, two-phase spiral CT findings including maximal thickness of the gastric wall, patterns of wall thickening, degree of contrast enhancement seen during the arterial and portal phase, the presence of perigastric strands, and lymphadenopathy are useful for

    The aim of this study was to investigate temperature and thermal dose distributions of thermobrachytherapy surface applicators (TBSAs) developed for concurrent or sequential high dose rate (HDR) brachytherapy and microwave hyperthermia treatment of chest wall recurrence and other superficial diseases. A steady-state thermodynamics model coupled with the fluid dynamics of a water bolus and electromagnetic radiation of the hyperthermia applicator is used to characterize the temperature distributions achievable with TBSAs in an elliptical phantom model of the human torso. Power deposited by 915 MHz conformal microwave array (CMA) applicators is used to assess the specific absorption rate (SAR) distributions of rectangular (500 cm 2 ) and L-shaped (875 cm 2 ) TBSAs. The SAR distribution in tissue and fluid flow distribution inside the dual-input dual-output (DIDO) water bolus are coupled to solve the steady-state temperature and thermal dose distributions of the rectangular TBSA (R-TBSA) for superficial tumor targets extending 10-15 mm beneath the skin surface. Thermal simulations are carried out for a range of bolus inlet temperature (T b = 38-43 deg. C), water flow rate (Q b = 2-4 L min -1 ) and tumor blood perfusion (ω b = 2-5 kg m -3 s -1 ) to characterize their influence on thermal dosimetry. Steady-state SAR patterns of the R- and L-TBSA demonstrate the ability to produce conformal and localized power deposition inside the tumor target sparing surrounding normal tissues and nearby critical organs. Acceptably low variation in tissue surface cooling and surface temperature homogeneity was observed for the new DIDO bolus at a 2 L min -1 water flow rate. Temperature depth profiles and thermal dose volume histograms indicate bolus inlet temperature (T b ) to be the most influential factor on thermal dosimetry. A 42 deg. C water bolus was observed to be the optimal choice for superficial tumors extending 10-15 mm from the surface even under significant blood perfusion

    To review the literature on chest wall resection for recurrent breast cancer and evaluate overall survival (OS) and quality-of-life (QOL) outcomes. Full-thickness chest wall resection for recurrent breast cancer is controversial, as historically these recurrences have been thought of as a harbinger of systemic disease. A systematic search in MEDLINE, EMBASE, and Cochrane CENTRAL identified 48 eligible studies, all retrospective, accounting for 1305 patients. The review is reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Primary end points were patient-centered QOL outcomes and OS; secondary outcomes included disease-free survival (DFS) and 30-day morbidity. Risk of bias was assessed using the Methodological Index for Non-Randomized Studies instrument and the Oxford Centre for Evidence-Based Medicine's levels of evidence tool. Random-effects meta-analysis was used to create pooled estimates. Meta-regressions and sensitivity analyses were used to explore study heterogeneity by age, year of publication, risk of bias, and surgical intent (curative vs palliative). Studies consistently reported excellent OS and DFS in properly selected patients. Pooled estimates for 5-year OS in all studies and those from the past 15 years were 40.8% [95% confidence interval (CI) 35.2-46.7) and 43.1% (95% CI 35.8-50.7), whereas pooled 5-year DFS was 27.1% (95% CI 16.6-41.0). Eight studies reported excellent outcomes related to QOL. Mortality was consistently low (<1%) and 30-day pooled morbidity was 20.2% (95% CI 15.3%-26.3%). Study quality varied, and risk of selection bias in included studies was high. Full-thickness chest wall resection can be performed with excellent survival and low morbidity. Few studies report on QOL; prospective studies should focus on patient-centered outcomes in this population.

    Dermatofibrosarcoma protuberans (Darrier-Ferrand sarcoma, DFSP) is an uncommon tumor. This sarcoma has a tendency to local recurrence, requiring a wide surgical resection. We report herein two cases of patients presenting with recurrent dermatofibrosarcoma protuberans after several surgical resections. A wide surgical resection with guided tissue regenaration has been performed in one case, whereas the second case required a skin graft. Despite a short follow-up, our aim was to highlight the local aggressiveness of the DFSP and point out its therapeutic challenge, usually requiring a wide and aggressive surgery.

    Following mastectomy and adjuvant external beam radiation therapy in patients with breast cancer, the incidence of local or locoregional recurrence is approximately 9 % (2-20 %). Alongside the often limited possibilities of surgical treatment, radiation therapy combined with superficial hyperthermia is the most effective local therapy. In the present work, a retrospective analysis of salvage brachytherapy combined with superficial hyperthermia for chest wall recurrences is presented. Between 2004 and 2011, 18 patients with a total of 23 target volumes resulting from chest wall recurrences after previously mastectomy and external beam radiation therapy (median 56 Gy, range 50-68 Gy) were treated with superficial brachytherapy as salvage treatment: 8 patients (44 %) had macroscopic tumor, 3 (17 %) had microscopic tumor (R1), and 7 (39 %) had undergone R0 resection and were treated due to risk factors. A dose of 50 Gy was given (high-dose rate [HDR] and pulsed-dose rate [PDR] procedures). In all, 5 of 23 patients (22 %) received additional concurrent chemotherapy, and in 20 of 23 (87 %) target volumes additional superficial hyperthermia was carried out twice weekly. The 5-year local recurrence-free survival was 56 %, the disease-free survival was 28 %, and a 5-year overall survival was 22 %. Late side effects Common Toxicity Criteria (CTC) grade 3 were reported in 17 % of the patients: 2 of 18 (11 %) had CTC grade 3 fibrosis, and 1 of 18 (6 %) had a chronic wound healing disorder. Re-irradiation as salvage brachytherapy with superficial hyperthermia for chest wall recurrences is a feasible and safe treatment with good local control results and acceptable late side effects.

    Full Text Available The treatment of colorectal diseases by videolaparoscopy (VL began in the 1990s, bringing multiple advantages in the treatment of cancers in general, especially benign tumors. Specifically, in case of colorectal cancer (CRC, the laparoscopic approach offers very attractive prospects, such as the staging of advanced lesions and palliative management of patients with incurable CCR. The most controversial aspect of this technique is the use of VL in curative resections. One questions the possibility of metastasis in portals related to tumor recurrence, as well as the violation of oncological principles. The mechanisms responsible for this phenomenon may be related to pneumoperitoneum, tissue manipulation, and biological factors. Resumo: O tratamento das doenças colorretais por vídeo-laparoscopia (VL se iniciou na década de 90, trazendo inúmeras vantagens no tratamento dos cânceres em geral, sobretudo nos cânceres benignos. Especificamente no caso do câncer colorretal (CCR o acesso laparoscópico oferece perspectivas bastante atraentes, como o estadiamento de lesões avançadas e o manuseio paliativo de pacientes com CCR incurável. O aspecto mais controverso dessa técnica reside na utilização da VL em ressecções curativas. Questiona-se a possibilidade de metástase em portais relacionadas com a recidiva tumoral, além da violação de princípios oncológicos. Os mecanismos responsáveis por esse fenômeno podem estar relacionados ao pneumoperitônio, manipulação tecidual e fatores biológicos.

    Only a few reports describe chest wall reconstruction after sternal resection using Gore-Tex dual mesh, and very few reports describe the use of a vascularized rib to support the thoracic cage. We present a case of a breast cancer patient who underwent anterior chest wall resection for recurrent sternal cancer. Her sternoclavicular joints bilaterally and lower sternum were divided using an electric saw. The bony chest wall was reconstructed using Gore-Tex dual mesh, and a vascularized rib was used to bridge the space between the clavicular heads to support the thoracic cage. The patient's postoperative course was uneventful, without complications, such as paradoxical respiration or pneumonia.

  12. The evolution of thoracic anesthesia.

    Brodsky, Jay B

    2005-02-01

    The specialty of thoracic surgery has evolved along with the modem practice of anesthesia. This close relationship began in the 1930s and continues today. Thoracic surgery has grown from a field limited almost exclusively to simple chest wall procedures to the present situation in which complex procedures, such as lung volume reduction or lung transplantation, now can be performed on the most severely compromised patient. The great advances in thoracic surgery have followed discoveries and technical innovations in many medical fields. One of the most important reasons for the rapid escalation in the number and complexity of thoracic surgical procedures now being performed has been the evolution of anesthesia for thoracic surgery. There has been so much progress in this area that numerous books and journals are devoted entirely to this subject. The author has been privileged to work with several surgeons who specialized in noncardiac thoracic surgery. As a colleague of 25 years, the noted pulmonary surgeon James B.D. Mark wrote, "Any operation is a team effort... (but) nowhere is this team effort more important than in thoracic surgery, where near-choreography of moves by all participants is essential. Exchange of information, status and plans are mandatory". This team approach between the thoracic surgeon and the anesthesiologist reflects the history of the two specialties. With new advances in technology, such as continuous blood gas monitoring and the pharmacologic management of pulmonary circulation to maximize oxygenation during one-lung ventilation, in the future even more complex procedures may be able to be performed safely on even higher risk patients.

    Primary chest wall tumors originate from different constructions of thoracic wall. We report our multidisciplinary experience on primary thoracic tumor resection and thoracic reconstruction, the need to additional therapy and evaluating prognostic factors affecting survival. We performed a retrospective review of our prospectively maintained database of 40 patients treated for malignant primary chest wall tumor from 1989 to 2009. Patients were evaluated in terms of age, sex, clinical presentation, type of imaging, tissue diagnosis methods, pathology, surgical technique, early complications, hospital mortality, prevalence of recurrence and distant metastases, additional treatment, 3 years survival and factors affecting survival. Male/Female (F/M) = 1, with median age of 43.72 years. Mass was the most common symptoms and the soft tissue sarcoma was the most common pathology. Resection without reconstruction was performed in 5 patients and Thirty-five patients (87.5%) had extensive resection and reconstruction with rotatory muscular flap, prosthetic mesh and/or cement. Overall, 12.5% (5/40) of patients received neoadjuvant therapy and 75% (30/40) of patients were treated with adjuvant therapy. The 3-year survival rate was 65%. Recurrences occurred in 24 patients (60%), 14 developed local recurrences, and 10 developed distant metastases. The primary treatment modality for both local and distant recurrences was surgical resection; among them, 10 underwent repeated resection, 9 adjuvant therapy and 5 were treated with lung metastasectomy. The most common site of distant metastasis was lung (n = 7). Factors that affected survival were type of pathology and evidence of distant metastasis. Surgery with wide margin is the safe and good technique for treatment of primary chest wall tumors with acceptable morbidity and mortality.

    We present a computational method for calculating the distribution of wall shear stress (WSS) in the aorta based on a velocity field obtained from two-dimensional (2D) phase-contrast magnetic resonance imaging (PC-MRI) data and a finite-element method. The WSS vector was obtained from a global least-squares stress-projection method. The method was benchmarked against the Womersley model, and the robustness was assessed by changing resolution, noise, and positioning of the vessel wall. To showcase the applicability of the method, we report the axial, circumferential and magnitude of the WSS using in-vivo data from five volunteers. Our results showed that WSS values obtained with our method were in good agreement with those obtained from the Womersley model. The results for the WSS contour means showed a systematic but decreasing bias when the pixel size was reduced. The proposed method proved to be robust to changes in noise level, and an incorrect position of the vessel wall showed large errors when the pixel size was decreased. In volunteers, the results obtained were in good agreement with those found in the literature. In summary, we have proposed a novel image-based computational method for the estimation of WSS on vessel sections with arbitrary cross-section geometry that is robust in the presence of noise and boundary misplacements.

    The incisional hernia continues to be a frequent complication of laparotomies. The purpose of study is the analysis of hernia disease relapse after one year after different open plasties methods of the abdominal wall. A prospective longitudinal study was performed that included 142 patients. An analysis was performed on the individual data, the level of obesity, intra-surgical variations in intra-abdominal pressure, the intensity of post-surgical pain, the post-surgical complications, and the types of plasties of abdominal wall, simple and with polypropylene mesh. The analysis of studied group showed a general rate of relapse of 16.9%, and within the 4 procedures, 40.74% in the case of simple plasties, of 16.07% after the only plasties, 6.97% after the retro-muscular plasties, and 6.25% after the full substitution of parietal defect. On analysing the collected, hernia relapse was statistically significantly related to the level of obesity, variations in intra-abdominal pressure, post-surgical pain, and the type of procedure performed. Hernia is a frequent complication of laparotomies. Hernia relapse was more frequent in the case of simple plasties. Among the mesh procedures, the onlay plasty showed a higher rate of relapse and post-surgical complications. Hernia relapse was more frequent in the case of variations of intra-abdominal pressure, and with increased post-surgical pain. The use of an echography examination may increase the accuracy of the presence of hernia disease. Copyright © 2015 Academia Mexicana de Cirugía A.C. All rights reserved.

    To analyze the initial thoracic involvement by CT in a consecutive series of patients with lymphoma. A retrospective analysis was made of thoracic CT studies made at the time of diagnosis of 259 patients with lymphoma. Mediastinal pulmonary, pleural, pericardial and chest wall involvement was assessed by CT. Of 259 patients (129 men y 130 women), 56 had Hodgkin's disease (HD) and 203 had non-Hodgkin lymphoma (NHL). Forty-two percent (42.5%, 110/259) of the patients had chest involvement on CT: 33 of 56 patients with HD (58.9%) and 77 of 203 patients with NHL (37.9%). All the patients with thoracic HD) and 71.4% of patients with thoracic NHL, had mediastinal lymph node involvement. of the patients with thoracic involvement 12.1% (4/33) of the patient with HD and 23.3% (18/77) of the patients with NHL had pulmonary involvement. Thoracic involvement on CT was more frequent in HD. Mediastinal lymph node involvement was the most common finding fundamentally in HD. Pulmonary disease always occurred in the presence of mediastinal lymph node involvement in HD but could occur as an isolated finding in NHL. (Author) 24 refs

    Full Text Available Thoracic spine pain, or thoracalgia, is one of the common reasons for seeking for medical advice. The epidemiology and semiotics of pain in the thoracic spine unlike in those in the cervical and lumbar spine have not been inadequately studied. The causes of thoracic spine pain are varied: diseases of the cardiovascular, gastrointestinal, pulmonary, and renal systems, injuries to the musculoskeletal structures of the cervical and thoracic portions, which require a thorough differential diagnosis. Facet, costotransverse, and costovertebral joint injuries and myofascial syndrome are the most common causes of musculoskeletal (nonspecific pain in the thoracic spine. True radicular pain is rarely encountered. Traditionally, treatment for thoracalgia includes a combination of non-drug and drug therapies. The cyclooxygenase 2 inhibitor meloxicam (movalis may be the drug of choice in the treatment of musculoskeletal pain.

    The role of thoracic spine related dysfunction in producing lower extremity symptoms is not clear. This case study describes the assessment and treatment of a patient with low back pain and bilateral lower extremity (BLE) symptoms. It was found that patient education about postural awareness and passive mobilization are valuable aids to decrease BLE symptoms due to sympathetic nervous system (SNS) dysfunction and lower thoracic hypomobility. The clinicians need to consider examination and treatment of the lower thoracic area in patients with BLE symptoms. More research is required to explore the role of SNS dysfunction in producing BLE symptoms.

    Thoracic outlet syndrome is a well-described disorder caused by thoracic outlet compression of the brachial plexus and/or the subclavian vessels. Neurogenic thoracic outlet syndrome is the most common manifestation, presenting with pain, numbness, tingling, weakness, and vasomotor changes of the upper extremity. Vascular complications of thoracic outlet syndrome are uncommon and include thromboembolic phenomena and swelling. The clinical presentation is highly variable, and no reproducible study exists to confirm the diagnosis; instead, the diagnosis is based on a physician's judgment after a meticulous history and physical examination. Both nonsurgical and surgical treatment methods are available for thoracic outlet syndrome. Whereas nonsurgical management appears to be effective in some persons, surgical treatment has been shown to provide predictable long-term cure rates for carefully selected patients. In addition, physicians who do not regularly treat patients with thoracic outlet syndrome may not have an accurate view of this disorder, its treatment, or the possible success rate of treatment.

    Rocca, M.; Salone, M.; Galletti, S.; Balladelli, A.; Vanel, D.; Briccoli, A.

    2013-01-01

    Primary malignant chest wall tumors are rare. The most frequent primary malignant tumor of the chest wall is chondrosarcoma, less common are primary bone tumors belonging to the Ewing Family Bone Tumors (EFBT), or even rarer are osteosarcomas. They represent a challenging clinical entities for surgeons as the treatment of choice for these neoplasms is surgical resection, excluding EFBT which are normally treated by a multidisciplinary approach. Positive margins after surgical procedure are the principal risk factor of local recurrence, therefore to perform adequate surgery a correct preoperative staging is mandatory. Imaging techniques are used for diagnosis, to determine anatomic site and extension, to perform a guided biopsy, for local and general staging, to evaluate chemotherapy response, to detect the presence of a recurrence. This article will focus on the role of imaging in guiding this often difficult surgery and the different technical possibilities adopted in our department to restore the mechanics of the thoracic cage after wide resections

    Thoracic endometriosis is considered to be rare, but is the most frequent form of extra-abdominopelvic endometriosis. Thoracic endometriosis syndrome affects women of reproductive age. Diagnosis is mainly based on clinical findings, which can include catamenial pneumothorax and haemothorax, non-catamenial endometriosis-related pneumothorax, catamenial haemoptysis, lung nodules, and isolated catamenial chest pain. Symptoms are typically cyclical and recurrent, with a right-sided predominance. Computed tomography (CT) is the first-line imaging method, but is poorly specific; therefore, its main role is to rule out other pulmonary diseases. However, in women with a typical clinical history, some key CT findings may help to confirm this often under-diagnosed syndrome. MRI can also assist with the diagnosis, by showing signal changes typical of haemorrhage within diaphragmatic or pleural lesions

    2009-03-01

    Chondrosarcoma of the chest wall is the most frequent primary malignant chest wall tumor. Surgery remains the only effective treatment. Sarcoma treatment in Sweden is centralized to sarcoma centers; however, sarcomas of the chest wall have also been handled by thoracic and general surgeons. One hundred six consecutive reports of chondrosarcomas of the rib and sternum over a 22-year period (1980 to 2002) were studied, with a median of 9 (4 to 23) years of follow-up for survivors. Clinical files were gathered and pathologic specimens reviewed and graded 1 to 4 by the Scandinavian sarcoma pathology group. Surgical margins were defined as wide, marginal, or intralesional. Ninety-seven patients were treated with a curative intent. Patients operated with wide surgical margins had a 10-year survival of 92% compared with 47% for those with intralesional resections. The 10-year survival was 75% for patients treated at sarcoma centers and 59% for those treated by thoracic or general surgeons. Local recurrence rate was highly dependent of the surgical margins-4% after wide resections and 73% after intralesional resections. The proportion of intralesional resections was higher outside sarcoma centers. Prognostic factors (multivariate analysis) for local recurrence included surgical margin and histological grade; for metastases, prognostic factors included histologic grade, tumor size, and local recurrence. Metastases occurred in 21 of the patients and only 2 were cured. Patients operated with wide surgical margins resulted in fewer local recurrences and better overall survival. Patients with chest wall tumors should be referred to sarcoma centers and not to general thoracic surgery clinics for diagnosis and treatment.

    We present here our institutional review of surgical treatment for the chest wall tumors. Chest wall resections were performed on 80 patients, and subsequent chest wall reconstructions were performed on 45 patients. Primary malignant tumors in the chest wall required more extensive rib resections combined with the neighboring structures such as the sternum and the vertebral bones than benign or metastatic/recurrent tumors did. Postoperative mortality and morbidity occurred in 5 patients who underwent the sternal resection and the rib resection combined with the vertebral bodies. Primary malignant tumors in the chest wall are sarcomas originating from the bones, the cartilage tissues, and the soft tissues of the chest wall. We general thoracic surgeons may not have expertise in treating sarcomas,because primary malignant chest wall tumors are rare and a single institution has limited experiences in surgical treatment of such tumors. We should be aware that a surgical margin of primary malignant chest wall tumors is important to achieve excellent local control and better prognosis. We recommend cooperation with an orthopedic oncologist who is experienced with treating sarcomas. Not only preoperative planning but also intraoperative evaluation for the surgical margin with orthopedic oncologists is necessary for better surgical outcome.

    A variety of diseases involve the esophagus including esophagitis, benign or malignant tumors, varices, and esophageal perforation. We reviewed the thoracic CT of these various esophageal diseases, and classified them by similar CT findings. The CT findings were circumferential wall thickening, nodular wall thickening, abnormal luminal dilatation, fistula formation, and mass or mass like lesion. Although CT alone has limited diagnostic ability in esophageal disease, it may have an important role in diagnosing submucosal dissection, fistula, perforation, and intramural abscess.

    Objective: the aim of this study was to analyze chest CT scans of patients with thoracic textiloma. Methods: this was a retrospective study of 16 patients (11 men and 5 women) with surgically confirmed thoracic textiloma. The chest CT scans of those patients were evaluated by two independent observers, and discordant results were resolved by consensus. Results: the majority (62.5%) of the textilomas were caused by previous heart surgery. The most common symptoms were chest pain (in 68.75%) and cough (in 56.25%). In all cases, the main tomographic finding was a mass with regular contours and borders that were well-defined or partially defined. Half of the textilomas occurred in the right hemithorax and half occurred in the left. The majority (56.25%) were located in the lower third of the lung. The diameter of the mass was ≤ 10 cm in 10 cases (62.5%) and > 10 cm in the remaining 6 cases (37.5%). Most (81.25%) of the textilomas were heterogeneous in density, with signs of calcification, gas, radiopaque marker, or sponge-like material. Peripheral expansion of the mass was observed in 12 (92.3%) of the 13 patients in whom a contrast agent was used. Intraoperatively, pleural involvement was observed in 14 cases (87.5%) and pericardial involvement was observed in 2 (12.5%). Conclusions: it is important to recognize the main tomographic aspects of thoracic textilomas in order to include this possibility in the differential diagnosis of chest pain and cough in patients with a history of heart or thoracic surgery, thus promoting the early identification and treatment of this postoperative complication.

    Chylothorax is a very rare complication of patients undergoing thoracic aortic aneurysm repair. Possible mechanisms of this condition during thoracic aorta operations and current therapeutic strategies are analyzed according to our experience and thorough search of the English literature. Current experience with chylothorax occurring during thoracic aortic surgery is analyzed in this review by collecting data retrieved from English literature research. Significant risk factors for postoperative chylothorax development after thoracic aorta surgical procedures are thoracic aortic reoperations and descending thoracic repairs. Various treatment modalities from conservative to operative intervention have been proposed. Currently, the morbidity and mortality have improved due to prompt management. Surgical intervention is needed when response to conservative treatment has failed.  © 2011 Wiley Periodicals, Inc.

    Full Text Available Effective thoracic mass is an important parameter in specifying mathematical and mechanical models (such as crash dummies of humans exposed to impact conditions. A method is developed using a numerical optimizer to determine effective thoracic mass (and mass distribution given a number of acceleration signals and a force signal response. Utilizing previously reported lateral and frontal impact tests with human cadaveric test specimens in a number of different conditions, the effective thoracic mass is computed. The effective thoracic masses are then computed for a variety of crash dummies exposed to identical test conditions.

    Introduction Thoracic outlet syndrome (TOS) is one of the most extensively discussed diagnoses. There is neither a clear and homogenous clinical presentation nor an accepted definition. The term describes a complex of symptoms and complaints caused by the compression of nerves and vascular structures at one of the three defined constrictions of the upper thoracic aperture. Methods Based on a comprehensive literature review, this article presents the etiology, epidemiology and clinical diagnostics as well as the possibilities and outcomes of surgical treatment. Results The thoracic outlet syndrome is currently subdivided into three main forms: vascular TOS (vasTOS) including arterial TOS (aTOS) and venous TOS (vTOS), neurogenic TOS (nTOS), which is further subdivided into typical (nTOS) and atypical TOS (disTOS), and a mixed form of nTOS and vasTOS (nvasTOS). The diagnosis is complex and difficult since the disTOS group comprises over 90 % of all patients. In addition to conservative treatment attempts, nTOS may be treated by surgical procedures focusing on the decompression of neurovascular structures. A significant improvement after surgery was found in up to 92 % of cases. The most common access sites are supraclavicular and transaxillary. 50 to 80 % of patients benefit from surgery in the long run. The rates of vascular or neurological complications reported by specialised centres are 0 to 2 %; minor complications such as pneumothorax, bleeding and lymphatic fistula are reported in up to 25 % of cases. Summary Most patients suffering from any form of TOS benefit from surgical treatment. Duration of symptoms, socioeconomic factors and, most notably, stringent diagnostic workup and an adequate operative procedure performed by an experienced centre are crucial to success.

    Public interest in the recent progress of tissue engineering, a special line of biotechnology, makes the current review on thoracic surgery highly relevant. In this article, techniques, materials and cellular processes are discussed alongside their potential applications in tissue repair. Different applications of tissue engineering in tracheo-bronchial replacement, lung tissue cultures and chest-wall reconstruction are also summarised in the article. Potential tissue engineering-based solutions for destructive, chronic lung-injury-related conditions and replacement of tubular structures in the central airways are also examined.

    The aim of the study was to determine the current state of training, utilization, and perceived value of nonvascular thoracic magnetic resonance imaging (MRI). The URL link for this anonymous, IRB-approved survey was e-mailed to all Society of Thoracic Radiology members with available e-mail addresses (733), of whom 693 were qualified to respond as per the survey's instructions. Survey questions focused on MRI training, interpretation volume, perceived value of thoracic MRI, and barriers to its utilization. Study data were collected and managed using Research Electronic Data Capture (REDCap) electronic data capture tools and analyzed with χ tests. The survey response rate was 27% (190/693). Thirty-seven percent (67/180) of respondents reported that they interpreted and reported zero thoracic MRIs and 64% (116/182) interpreted or reported perceived value of thoracic MRI was highest for chest wall and neurovascular involvement and evaluation of the mediastinum, particularly thymus, next highest for assessment of pleural or diaphragmatic lesions, and lowest for assessment of lung function with hyperpolarized gases. Seventy-three percent (121/166) of respondents felt it would be of value to increase utilization of thoracic MRI. Perceived obstacles to increasing thoracic MRI utilization included lack of: awareness of referring health care providers as to the value of thoracic MRI (59%, 98/166), radiologist proficiency or comfort with thoracic MRI (46%, 77/166), standardized protocols (38%, 64/166), technologist experience (38%, 63/166), and sufficient training during residency and/or fellowship (32%, 54/166). Twenty-five percent (41/166) of respondents reported insufficient thoracic MRI literature and limited CME courses and lectures in this field as an additional impediment. The majority of survey respondents reported limited experience in thoracic MRI interpretation, a recognition of thoracic MRI's value, and an interest in increasing its utilization. Improved

    Purpose: We determined cumulative dose to critical structures, rates of toxicity, and outcomes following thoracic reirradiation. Methods and Materials: We retrospectively reviewed our institutional database for patients treated between 2008 and 2014, who received thoracic reirradiation with overlap of 25% prescribed isodose lines. Patients received courses of hyperfractionated (n=5), hypofractionated (n=5), conventionally fractionated (n=21), or stereotactic ablative radiation therapy (n=51). Doses to critical structures were converted to biologically effective dose, expressed as 2 Gy per fraction equivalent dose (EQD2; α/β = 2 for spinal cord; α/β = 3 for other critical structures). Results: We identified 82 courses (44 for retreatment) in 38 patients reirradiated at a median 16 months (range: 1-71 months) following initial RT. Median follow-up was 17 months (range: 3-57 months). Twelve- and 24-month overall survival rates were 79.6% and 57.3%, respectively. Eighteen patients received reirradiation for locoregionally recurrent non-small cell lung cancer with 12-month rates of local failure and regional recurrence and distant metastases rates of 13.5%, 8.1%, and 15.6%, respectively. Critical structures receiving ≥75 Gy EQD2 included spinal cord (1 cm{sup 3}; n=1), esophagus (1 cm{sup 3}; n=10), trachea (1 cm{sup 3}; n=11), heart (1 cm{sup 3}; n=9), aorta (1 cm{sup 3}; n=16), superior vena cava (1 cm{sup 3}; n=12), brachial plexus (0.2 cm{sup 3}; n=2), vagus nerve (0.2 cm{sup 3}; n=7), sympathetic trunk (0.2 cm{sup 3}; n=4), chest wall (30 cm{sup 3}; n=12), and proximal bronchial tree (1 cm{sup 3}; n=17). Cumulative dose-volume (D cm{sup 3}) toxicity following reirradiation data included esophagitis grade ≥2 (n=3, D1 cm{sup 3} range: 41.0-100.6 Gy), chest wall grade ≥2 (n=4; D30 cm{sup 3} range: 35.0-117.2 Gy), lung grade 2 (n=7; V20{sub combined-lung} range: 4.7%-21.7%), vocal cord paralysis (n=2; vagus nerve D0.2 cm{sup 3

    Full Text Available Hemangiopericytoma (HPC may develop in every site where the endothelial tissue exits and primarily develops in the skeletal-muscular system or the skin. Adult cases of HPC generally exhibit a benign course. 20–30% of the cases may show a malign course. The tumors that show more than four mitoses, a focal area of necrosis, and increased cellularity on a magnification ×10 are considered as malign. In our paper, we presented our case who showed a lung metastasis at the end of 4 years and who developed a pathological fracture of the right humerus at the end of approximately 2 years, because hemangiopericytoma is rarely seen in the chest wall as a primary tumor.

    This article presents an overview of factors associated with thoracic transplantation outcomes over the past decade and provides valuable information regarding the heart, lung, and heart-lung waiting lists and thoracic organ transplant recipients. Waiting list and post-transplant information is used to assess the importance of patient demographics, risk factors, and primary cardiopulmonary disease on outcomes. The time that the typical listed patient has been waiting for a heart, lung, or heart-lung transplant has markedly increased over the past decade, while the number of transplants performed has declined slightly and survival after transplant has plateaued. Waiting list mortality, however, appears to be declining for each organ and for most diseases and high-severity subgroups, perhaps in response to recent changes in organ allocation algorithms. Based on perceived inequity in organ access and in response to a mandate from Health Resources and Services Administration, the lung transplant community is developing a lung allocation system designed to minimize deaths on the waiting list while maximizing the benefit of transplant by incorporating post-transplant survival and quality of life into the algorithm. Areas where improved data collection could inform evolving organ allocation and candidate selection policies are emphasized.

    The damage control surgery came up with the philosophy of applying essential maneuvers to control bleeding and abdominal contamination in trauma patients who are within the limits of their physiological reserves. This concept was extended to thoracic injuries, where relatively simple maneuvers can shorten operative time of in extremis patients. This article aims to revise the various damage control techniques in thoracic organs that must be known to the surgeon engaged in emergency care. RESUMO A cirurgia de controle de danos surgiu com a filosofia de se aplicar manobras essenciais para controle de sangramento e contaminação abdominal, em doentes traumatizados, nos limites de suas reservas fisiológicas. Este conceito se estendeu para as lesões torácicas, onde manobras relativamente simples, podem abreviar o tempo operatório de doentes in extremis. Este artigo tem como objetivo, revisar as diversas técnicas de controle de dano em órgãos torácicos, que devem ser de conhecimento do cirurgião que atua na emergência.

Todos os animais foram submetidos à ressecção costal na porção média do tórax abrangendo a 7ª, 8ª e 9ª costelas e posterior implante de cartilagem conchal heteróloga conservada em glicerina a 98%. No GI, foi preservada a musculatura adjacente, já no GII, a musculatura foi retirada. Os animais foram avaliados clinicamente no pós-operatório e, ao final do período, submetidos à eutanásia e necropsia para avaliação macroscópica e microscópica da região do implante. Observou-se proliferação de tecido fibrovascular neovascularizado sobre o implante, com aderência pulmonar e diafragmática em algumas das unidades experimentais. O implante de cartilagem heteróloga conservado em glicerina a 98% pode ser utilizado para reconstrução de parede costal cujo defeito abranja o espaço de parte de três costelas. O implante em 60 dias é substituído por tecido cicatricial, sem apresentar sinais clínicos de rejeição.Twelve adult cats were divided in groups GI and GII with the objective of testing a dog auricular cartilage implant conserved in 98% glycerin as an alternative to repair thoracic wall defects.

    [Purpose] The purpose of this study was to investigate the effect of thoracic stretching, a thoracic extension exercise and exercises for cervical and scapular posture on thoracic kyphosis angle and upper thoracic pain. [Subject] A 36-year-old male, who complained of upper thoracic pain at the T1-4 level with forward head and round shoulders, was the subject. [Methods] He performed thoracic stretching (session 1), a thoracic extension exercise (session 2), and muscle exercises for cervical and scapular posture (session 3). [Results] The upper thoracic pressure pain threshold increased after session 1, session 2, and session 3. The thoracic kyphosis angle decreased after session 1, session 2, and session 3. [Conclusion] We suggest that intervention for thoracic pain or kyphotic thoracic correction should use not only an approach for extending the thoracic muscles, but also an approach treating muscles in the cervical and scapular region.

    Purpose: To study the impact of dose fractionation of adjuvant radiation therapy (RT) on local recurrence (LR) and the relation of LR to radiation fields. Methods and Materials: LR rates were analyzed in 462 adult patients with soft tissue sarcoma who underwent surgical excision and adjuvant RT at five Scandinavian sarcoma centers from 1998 to 2009. Medical records were reviewed for dose fractionation parameters and to determine the location of the LR relative to the radiation portals. Results: Fifty-five of 462 patients developed a LR (11.9%). Negative prognostic factors included intralesional surgical margin (hazard ratio [HR]: 7.83, 95% confidence interval [CI]: 3.08-20.0), high malignancy grade (HR: 5.82, 95% CI: 1.31-25.8), age at diagnosis (HR per 10 years: 1.27, 95% CI: 1.03-1.56), and malignant peripheral nerve sheath tumor histological subtype (HR: 6.66, 95% CI: 2.56-17.3). RT dose was tailored to margin status. No correlation between RT dose and LR rate was found in multiple Cox regression analysis. The majority (65%) of LRs occurred within the primary RT volume. Conclusions: No significant dose–response effect of adjuvant RT was demonstrated. Interestingly, patients given 45-Gy accelerated RT (1.8 Gy twice daily/2.5 weeks) had the best local outcome. A total dose of 50 Gy in 25 fractions seemed adequate following wide margin surgery. The risk of LR was associated with histopathologic subtype, which should be included in the treatment algorithm of adjuvant RT in soft tissue sarcoma.

  13. Vascular Thoracic Outlet Syndrome.

    Two distinct terms are used to describe vascular thoracic outlet syndrome (TOS) depending on which structure is predominantly affected: venous TOS (due to subclavian vein compression) and arterial TOS (due to subclavian artery compression). Although the venous and arterial subtypes of TOS affect only 3% and <1% of all TOS patients respectively, the diagnostic and management approaches to venous and arterial TOS have undergone considerable evolution due to the recent emergence of minimally invasive endovascular techniques such as catheter-directed arterial and venous thrombolysis, and balloon angioplasty. In this review, we discuss the anatomical factors, etiology, pathogenesis and clinical presentation of vascular TOS patients. In addition, we use the most up to date observational evidence available to provide a contemporary approach to the diagnosis and management of venous TOS and arterial TOS patients.

    2016-01-01

    Tuberculosis (TB) is a granulomatous disease caused by Mycobacterium tuberculosis and transmission is via an airborne route by droplet infection. In the majority of cases patients have thoracic TB, which most frequently presents with hilar lymphadenopathy and pulmonary manifestation. Due to the rise in incidence of TB in central Europe to be expected over the coming years, it is essential to be acquainted with the radiological manifestations of pulmonary TB, particularly to be able to discriminate active from inactive TB. Due to the use of molecular techniques entailing DNA fingerprinting, the traditional classification of TB in primary and postprimary TB is being challenged. These genetic studies have revealed that variations in the clinical and radiographic appearance of TB are mainly affected by the immune status of the patients. Due to the low prevalence of TB in central Europe and the wide variation of radiological presentations, the diagnosis and therapy of TB is often delayed. In this article, the radiographic manifestations of thoracic TB are summarized and discussed. Together with the medical history and bacteriological tests, chest X-ray imaging and computed tomography (CT) play a major role not only in the detection of TB but also in the follow-up during and after therapy. Chest X-radiographs should be the primary diagnostic method in patients with suspected TB in screening as well as for diagnosis and therapy monitoring. The use of CT is more sensitive than chest radiographs and is frequently performed after chest radiographs to obtain detailed information about subtle parenchymal changes or lymph node manifestation. When active TB is suspected CT should be performed. Tree in bud, lobular consolidations, centrilobular nodules, cavities and ground-glass opacification are typical changes in active TB. (orig.) [de

    A case study of a patient with Ewing sarcoma of T8 and T9 with paravertebral and chest wall involvement, who underwent neoadjuvant chemotherapy and subsequent multilevel en bloc spondylectomy and chest wall excision using a simultaneous anterior and posterior approach. To show the feasibility of treating Ewing sarcoma of the thoracic spine with paravertebral and chest wall extension by multiagent chemotherapy followed by a multilevel en bloc spondylectomy and chest wall excision using a simultaneous anterior and posterior approach. Ewing sarcoma is a primary malignant bone tumor that occasionally involves the spinal column. Most patients with Ewing sarcoma of the spine are treated with systemic chemotherapy followed by definitive local control. Radiation therapy is the usual mode of local control in these patients because the spinal column has historically been considered a surgically inaccessible site where wide surgical margins are difficult to obtain. However, en bloc spondylectomy techniques have been described that can probably further decrease the risk of local recurrence, thereby minimizing or even eliminating the need for radiation therapy. To our knowledge, a combined en bloc spondylectomy and chest wall excision in a patient with Ewing sarcoma in the spine has not been previously reported. Neoadjuvant chemotherapy consisting of vincristine, doxorubicin, and cyclophosphamide was administered. After completion of the chemotherapy, an en bloc spondylectomy of T8 and T9 with removal of the chest wall was achieved using a simultaneous anterior and posterior approach to the spine. A stackable carbon fiber cage filled with autograft and allograft bone was inserted between T7 and T10. The spine was stabilized with anterior and posterior instrumentation. The chest wall was reconstructed with contoured polymethylmethacrylate and polypropylene (Marlex, Textile Development Associates, Inc., Franklin Square, NY) mesh. The patient maintained normal neurologic function

    The present study aims to elucidate the frequency of thoracic outlet syndrome after the Nuss procedure for pectus excavatum and the conditions in which thoracic outlet syndrome is likely to develop. A retrospective study including 85 pectus excavatum patients (58 males and 27 females) was conducted. Thoracic outlet syndrome was defined as a condition in which the patient has numbness, lassitude, or pain of the upper limbs at rest or during motion of the upper limbs. The frequency of the thus-defined thoracic outlet syndrome was evaluated in 85 patients. Age, sex, Haller indices, and the positions of the correction bars were compared between the patients who developed thoracic outlet syndrome and those who did not. Preadolescent patients (18 out of 85) did not develop postoperative thoracic outlet syndrome. In total, 15.2% of adult male patients (7 out of 46) and 33% of adult female patients (7 out of 21) developed postoperative thoracic outlet syndrome. For both male and female groups, Haller indices were significantly greater for patients who had postoperative thoracic outlet syndrome than for those who did not. Correction bars were generally placed at higher intercostal spaces in patients who developed postoperative thoracic outlet syndrome than in those who did not. A considerable percentage of adult patients develop thoracic outlet syndrome after the Nuss procedure for pectus excavatum. Maturity of the thoracic wall, femininity, severity of the deformity (represented by greater Haller indices), and placement of correction bars at superior intercostal spaces are risk factors for postoperative thoracic outlet syndrome.

    Objective: To compare the efficacy of British Thoracic Society and American Thoracic Society guidelines for re-introduction of anti-tuberculous therapy after drug-induced liver injury, and to assess the ease of administration of each guideline on a scale of 1-10. Methods: The randomised prospective interventional study was conducted at the Department of Medicine and Pulmonology, Dow University of Health Sciences, Karachi, from December 2011 to November 2013. Patients with anti-tuberculous therapy drug-induced liver injury were selected. Hepatotoxic anti-tuberculous therapy was stopped and modified anti-tuberculous therapy was started. Patients were followed weekly till clinical and biochemical parameters got stabilised. After stabilisation, the patients were randomised to one of the two groups to receive re-introduction of anti-tuberculous therapy under the guidelines of British Thoracic Society (Group I) or those of American Thoracic Society (Group II). Means of the groups were analysed by Student's t test and proportions were compared by chi-square test. Multivariate analysis was done for age, body mass index and serum albumin for recurrence of drug-induced liver injury after the re-introduction. P value <0.05 was taken as significant. Results: Of the total 325 patients, 163(50.15%) were in Group I, while 162(49.84%) were in Group II. The frequency of recurrence of drug-induced liver injury in Group I was 16 (9.8%) and in Group II it was 18 (11.1%). There was no statistically significant difference between the two groups (p<0.7). Age was positively related with drug-induced liver injury, while body mass index and serum albumin were negatively associated. Conclusion: There was no significant difference between the two major guidelines though the American Thoracic Society guideline was easier to follow. (author)

    Full Text Available Primary hydatid disease of spine is rare and spinal hydatitosis constitute only 1% of all hydatitosis. We report a case of recurrent primary intraspinal extradural hydatid cyst of the thoracic region causing progressive paraparesis. The patient was operated 16 years ago for primary spinal hydatid disease involvement and was instrumented dorsally for stabilization. The magnetic resonance imaging (MRI of thoracic spine showed a cystic lesion at T11-12 level and compressed spinal cord posterolaterally. Intraspinal cyst was excised through T11-12 laminectomy which made formerly. The early postoperative period showed a progressive improvement of his neurological deficit and he was discharged with antihelmintic treatment consisting of albendazole and amoxicillin-sulbactam combination.

    Chest CT scans of 70 patients with malignant lymphoma were reviewed to evaluate the thoracic manifestation of malignant lymphoma. Sixteen patients had Hodgkin's disease and 54 patients had non-Hodgkin's lymphoma. The thoracic involvement of malignant lymphoma was observed i 47 patients (67.1%) and 11 of these patients had Hodgkin's disease, and 36 had non-Hodgkin's lymphoma. The most common finding was mediastinal lymphadenopathy and the most frequently involved sites were anterior mediastinal and paratracheal lymph nodes. Pulmonary parenchymal involvement was seen in 11 patients (15.7%), and CT scan showed thickening of bronchovascular bundle, parenchymal consolidation and nodules. Pleural effusion was seen in 18 patients (25.7%), however, without any evidence of parietal pleural thickening in all cases. Involvement of chest wall and breast was seen in two patient (2.9%). The data obtained through the current study showed no differences from those of previous reports, except the fact that there was no CT evidence of pleural thickening in patients who had pleural effusion

  1. Recurrent Meningitis.

    Recurrent meningitis is a rare clinical scenario that can be self-limiting or life threatening depending on the underlying etiology. This review describes the causes, risk factors, treatment, and prognosis for recurrent meningitis. As a general overview of a broad topic, the aim of this review is to provide clinicians with a comprehensive differential diagnosis to aide in the evaluation and management of a patient with recurrent meningitis. New developments related to understanding the pathophysiology of recurrent meningitis are as scarce as studies evaluating the treatment and prevention of this rare disorder. A trial evaluating oral valacyclovir suppression after HSV-2 meningitis did not demonstrate a benefit in preventing recurrences. The data on prophylactic antibiotics after basilar skull fractures do not support their use. Intrathecal trastuzumab has shown promise in treating leptomeningeal carcinomatosis from HER-2 positive breast cancer. Monoclonal antibodies used to treat cancer and autoimmune diseases are new potential causes of drug-induced aseptic meningitis. Despite their potential for causing recurrent meningitis, the clinical entities reviewed herein are not frequently discussed together given that they are a heterogeneous collection of unrelated, rare diseases. Epidemiologic data on recurrent meningitis are lacking. The syndrome of recurrent benign lymphocytic meningitis described by Mollaret in 1944 was later found to be closely related to HSV-2 reactivation, but HSV-2 is by no means the only etiology of recurrent aseptic meningitis. While the mainstay of treatment for recurrent meningitis is supportive care, it is paramount to ensure that reversible and treatable causes have been addressed for further prevention.

    Full Text Available Chest wall neoplasms mainly include malignancies, metastatic in particular. Differential diagnosis should include clinical data; tumor location, extent, delineation; the degree of homogeneity; the presence of calcifications; the nature of bone destruction and the degree of vascularization. The aim of the paper is to present both the benefits and limitations of ultrasound for the diagnosis of chest wall neoplasms. The neoplastic process may be limited to the chest wall; it may spread from the chest wall into the intrathoracic structures or spread from the inside of the chest towards the chest wall. Benign tumors basically originate from vessels, nerves, bones, cartilage and soft tissues. In this paper, we briefly discuss malformations of blood and lymphatic vessels, glomus tumor as well as neurogenic tumors originating in the thoracic branches of the spinal nerves and the autonomic visceral system. Metastases, particularly lung, breast, kidney cancer, melanoma and prostate cancer, are predominant tumors of the osteocartilaginous structures of the chest wall. Plasma cell myeloma is also relatively common. The vast majority of these lesions are osteolytic, which is reflected in ultrasound as irregular cortical defects. Osteoblastic foci result only in irregular outline of the bone surface. Lipomas are the most common neoplasms of the chest wall soft tissue. Elastofibroma is another tumor with characteristic echostructure. Desmoid fibromatosis, which is considered to be a benign lesion with local aggressivity and recurrences after surgical resection, represents an interesting tumor form the clinical point of view. Ultrasonography represents an optimal tool for the monitoring of different biopsies of pathological lesions located in the chest wall. Based on our experiences and literature data, this method should be considered as a preliminary diagnosis of patients with chest wall tumors.

    Systemic cholesterol embolism is a rare complication of atherosclerosis, and has various presentations. Arterial catheterisms are a common cause. However, the association with an aortic dissection has been exceptionally reported. We report the observation of a 70 year-old man, with coronary artery disease, hypertension, diabetes and dyslipidemia. Six months before hospitalization, a coronary angioplasty was performed due to recurrent angina. The association of purpuric lesions on the feet, with acute renal failure confirmed cholesterol embolism syndrome. Transoesophageal echocardiography showed a dissection of the descending thoracic aorta associated with complex atheroma. The evolution was marked by the pulpar necrosis of a toe and by a worsening of the renal failure, requiring definitive hemodialysis. Further echographic control highlighted the rupture of the intimal veil of the dissection. Cholesterol embolism syndrome may reveal an aortic dissection in patients without thoracic symptoms. In such cases, transoesophageal echocardiography is a useful and non-invasive examination.

    Photodynamic therapy has a role in the management of early and late thoracic malignancies. It can be used to facilitate minimally-invasive treatment of early endobronchial tumours and also to palliate obstructive and bleeding effects of advanced endobronchial tumours. Photodynamic therapy has been used as a means of downsizing tumours to allow for resection, as well as reducing the extent of resection necessary. It has also been used successfully for minimally-invasive management of local recurrences, which is especially valuable for patients who are not eligible for radiation therapy. Photodynamic therapy has also shown promising results in mesothelioma and pleural-based metastatic disease. As new generation photosensitizers are being developed and tested and methodological issues continue to be addressed, the role of photodynamic therapy in thoracic malignancies continues to evolve.

    We report a rare case of recurrent thymoma with pleural dissemination invading the intervertebral foramen. A woman with Masaoka's stage IVa thymoma with myasthenia gravis (MG) underwent macroscopically complete resection. After 45 months, she developed back pain. Computed tomography (CT) of the chest demonstrated a mass in the right thoracic cavity invading the intervertebral foramen between thoracic vertebrae 10 and 11. She underwent complete resection of the tumor and postoperative radiotherapy. The resected specimen was histologically diagnosed as a pleural dissemination from thymoma. There has been no local recurrence.

    Full Text Available Abstract Background Elastofibromas are benign soft tissue tumours mostly of the infrascapular region between the thoracic wall, the serratus anterior and the latissimus dorsi muscle with a prevalence of up to 24% in the elderly. The pathogenesis of the lesion is still unclear, but repetitive microtrauma by friction between the scapula and the thoracic wall may cause the reactive hyperproliferation of fibroelastic tissue. Methods We present a series of seven cases with elastofibroma dorsi with reference to clinical findings, further clinical course and functional results after resection, as well as recurrence. Data were obtained retrospectively by clinical examination, phone calls to the patients' general practitioners and charts review. Follow-up time ranged from four months to nine years and averaged 53 months. Results The patients presented with swelling of the infrascapular region or snapping scapula. In three cases, the lesion was painful. The ratio men/women was 2/5 with a mean age of 64 years. The tumor sizes ranged from 3 to 13 cm. The typical macroscopic aspect was characterized as poorly defined fibroelastic soft tissue lesion with a white and yellow cut surface caused by intermingled remnants of fatty tissue. Microscopically, the lesions consisted of broad collagenous strands and densely packed enlarged and fragmented elastic fibres with mostly round shapes. In all patients but one, postoperative seroma (which had to be punctuated occurred after resection; however, at follow-up time, no patient reported any decrease of function or sensation at the shoulder or the arm of the operated side. None of the patients experienced a relapse. Conclusion In differential diagnosis of soft tissue tumors located at this specific site, elastofibroma should be considered as likely diagnosis. Due to its benign behaviour, the tumor should be resected only in symptomatic patients.

    Rheumatoid arthritis is a relatively common multisystem disease associated with significant mortality and morbidity. Thoracic disease, both pleural and pulmonary, is a frequent extra-articular manifestation of rheumatoid arthritis and responsible for approximately 20% of rheumatoid-associated mortality. Rheumatoid disease and its associated therapies can affect all compartments of the lung inciting a range of stereotyped pathological responses and it is not infrequent for multiple disease entities to co-exist. In some instances, development of pulmonary complications may precede typical rheumatological presentation of the disease and be the first indication of an underlying connective tissue disease. The spectrum of thoracic disease related to rheumatoid arthritis is reviewed

    We report a case of vascular thoracic outlet syndrome in a young man, diagnosed with upper limb arteriography, leading to repeated arterio-arterial emboli originating from a post-stenotic subclavian artery aneurysm. It is of our interest due to its low incidence and the small number of cases reported that have been diagnosed by arteriography. The thoracic outlet is the path through which vascular and neural structures goes from the neck to the axilla, and it has three anatomical strictures, that when pronounced, can compress the brachial plexus or subclavian vessels, leading to different symptoms and signs.

  12. Respiratory Effects of Thoracic Load Carriage Exercise and Inspiratory Muscle Training as a Strategy to Optimize Respiratory Muscle Performance with Load Carriage.

    Shei, Ren-Jay; Chapman, Robert F; Gruber, Allison H; Mickleborough, Timothy D

    2017-12-01

    Many occupational and recreational settings require the use of protective and/or load-bearing apparatuses worn over the thoracic cavity, known as thoracic load carriage (LC). Compared to normal, unloaded exercise, thoracic LC exercise places an additional demand on the respiratory and limb locomotor systems by altering ventilatory mechanics as well as circulatory responses to exercise, thus accelerating the development of fatigue in the diaphragm and accessory respiratory muscles compared to unloaded exercise. This may be a consequence of the unique demands of thoracic LC, which places an additional mass load on the thoracic cavity and can restrict chest wall expansion. Therefore it is important to find effective strategies to ameliorate the detrimental effects of thoracic LC. Inspiratory muscle training is an intervention that aims to increase the strength and endurance of the diaphragm and accessory inspiratory muscle and may therefore be a useful strategy to optimize performance with thoracic LC.

    Full Text Available Equine Recurrent Airway Obstruction (RAO, also known as heaves or broken wind, is one of the most common disease in middle-aged horses. Inflammation of the airway is inducted by organic dust exposure. This disease is characterized by neutrophilic inflammation, bronchospasm, excessive mucus production and pathologic changes in the bronchiolar walls. Clinical signs are resolved in 3-4 weeks after environmental changes. Horses suffering from RAO are susceptible to allergens throughout their lives, therefore they should be properly managed. In therapy the most importanthing is to eliminate dustexposure, administration of corticosteroids and use bronchodilators to improve pulmonary function.

  14. Recurrent diverticulitis.

    Comparato, Giuseppe; Di Mario, Francesco

    2008-01-01

    The term "diverticulitis" indicates the inflammation of a diverticulum or diverticula, which is accompanied by detectable or microscopical perforation. Diverticulitis is a common condition with an estimated incidence of 25%. At present, elective sigmoid resection is recommended after 2 episodes of uncomplicated diverticulitis to prevent the serious complications of recurrent colonic diverticulitis. This guideline has been based on the assumption that recurrent episodes (2 or more) of diverticulitis will lead to complicated diverticulitis and higher mortality. The data to support this assumption are based on only a few small studies. Advances in diagnostic modalities, medical therapy, and surgical techniques over the past 2 decades have changed both the management and outcomes of diverticulitis. Many authors have shown that patients treated nonoperatively have a low risk of recurrent disease and would be expected to do well without elective colectomy.

    2017-05-01

    Recurrent pericarditis is the most troublesome complication of pericarditis occurring in 15 to 30% of cases. The pathogenesis is often presumed to be immune-mediated although a specific rheumatologic diagnosis is commonly difficult to find. The clinical diagnosis is based on recurrent pericarditis chest pain and additional objective evidence of disease activity (e.g. pericardial rub, ECG changes, pericardial effusion, elevation of markers of inflammation, and/or imaging evidence of pericardial inflammation by CT or cardiac MR). The mainstay of medical therapy for recurrent pericarditis is aspirin or a non-steroidal anti-inflammatory drug (NSAID) plus colchicine. Second-line therapy is considered after failure of such treatments and it is generally based on low to moderate doses of corticosteroids (e.g. prednisone 0.2 to 0.5 mg/kg/day or equivalent) plus colchicine. More difficult cases are treated with combination of aspirin or NSAID, colchicine and corticosteroids. Refractory cases are managed by alternative medical options, including azathioprine, or intravenous human immunoglobulins or biological agents (e.g. anakinra). When all medical therapies fail, the last option may be surgical by pericardiectomy to be recommended in well-experienced centres. Despite a significant impairment of the quality of life, the most common forms of recurrent pericarditis (usually named as "idiopathic recurrent pericarditis" since without a well-defined etiological diagnosis) have good long-term outcomes with a negligible risk of developing constriction and rarely cardiac tamponade during follow-up. The present article reviews current knowledge on the definition, diagnosis, aetiology, therapy and prognosis of recurrent pericarditis with a focus on the more recent available literature.

    Osteoblastoma is an uncommon, benign osteoblastic tumor accounting for osteoblastoma is a variant of osteoblastoma and is considered to be a borderline or intermediate osteoblastic tumor, first defined by Dorfman and Weiss in 1984. As a rare tumor, its true incidence and distribution are not clearly known. Treatment of osteoblastoma is complete surgical excision by either curettage or en bloc technique. Recurrence is seen in 10% to 15% of cases, and aggressive osteoblastoma are more likely to recur (osteoblastoma. This article reports a rare case of recurrent aggressive osteoblastoma of the thoracic spine, successfully treated by total en bloc spondylectomy. Treatment options for such a highly recurrent benign tumor are discussed.

    Hydatid disease, a worldwide zoonosis, is caused by the larval stage of the Echinococcus tapeworm. Although it can involve almost every organ of the body, lung involvement follows in frequency the hepatic infestation in adults and is the predominating site in children. Radiologically, hydatidosis usually demonstrates typical findings, but many patients are at risk of developing various complications of hydatid disease with atypical imaging findings and these are rarely described in the literature. In this pictorial review, the imaging features of local complications of hydatid disease involving the thorax including intrapulmonary or pleural rupture, infection of the ruptured cysts, reactions of the adjacent tissues, thoracic wall invasion and iatrogenic involvement of pleura are described. Additionally, imaging characteristics of transdiaphragmatic thoracic involvement of hepatic hydatid disease are presented. To prevent the development of subsequent catastrophic results, all radiologists need to be aware of the atypical imaging appearances of complications of pulmonary hydatid disease.

  1. Breast size, bra fit and thoracic pain in young women: a correlational study.

    A single sample study was undertaken to determine the strength and direction of correlations between: a) breast size and thoracic spine or posterior chest wall pain; b) bra fit and thoracic spine or posterior chest wall pain and; c) breast size and bra fit, in thirty nulliparous women (18-26 years), with thoracic spine or posterior chest wall pain, who wore bras during daytime. Pain (Short Form McGill Pain Questionnaire), bra size (Triumph International), bra fit (Triumph International). Most (80%) women wore incorrectly sized bras: 70% wore bras that were too small, 10% wore bras that were too large. Breast size was negatively correlated with both bra size (r = -0.78) and bra fit (r = -0.50). These results together indicate that large breasted women were particularly likely to be wearing incorrectly sized and fitted bras. Negligible relationships were found between pain and bra fit, and breast size and pain. Menstrual cycle stage was moderately positively correlated with bra fit (r = 0.32). In young, nulliparous women, thoracic pain appears unrelated to breast size. Bra fit is moderately related to stage of menstrual cycle suggesting that this research may be somewhat confounded by hormonal changes or reproductive stage. Further research is needed to clarify whether there is a relationship between breast size or bra fit and thoracic pain in women during times of hormonal change.

    In a report describing life ending fractures (255 horses) from the Livestock Disease Diagnostic Center, Kentucky (1993 and 1994), 32 foals had rib fractures. The purpose of our study was to examine the incidence of rib fractures in newborn foals on a Thoroughbred studfarm by physical and radiographic examination, to determine factors which may contribute to the problem and to document any clinical consequences. All foals (263) included were examined within 3 days of birth. The thoracic cage was palpated externally for abnormalities and all foals were placed in dorsal recumbency to evaluate thoracic cage symmetry. Radiographs were used to diagnose foals with thoraciccage asymmetry (TCA) and rib fracture (RF). A diagnosis of costochondral dislocation (CD) was made when no radiographic evidence of fracture was present but there was severe TCA, Fifty-five foals (20.1%) had TCA (9 RF), One to 5 ribs were fractured on 9 of 40 radiographic studies. No consequences of the thoracic trauma was detected clinically, radiographically or ultrasonographically in this group of foals or at a 2- and 4-week follow-up examination. The percentage of foals with a history of abnormal parturition was higher in the TCA foals (15%) compared to the normal foals (6.8%). There weremore primiparous dams in the TCA group than in the normal foal group. Fillies (56.6%) had a higher incidence of birth trauma than colts (43.4%), Thisstudy demonstrates that thoracic trauma is often present in newborn foals and may not always be of clinical significance. Dystocia foals and foals from primiparous mares should be considered high risk for thoracic trauma

    Primary malignant bone tumours and soft tissue sarcomas of the chest wall are exceedingly rare entities. The aim of this study was a retrospective two-institutional analysis of surgical therapy with respect to the kind and amount of the resection performed, the type of reconstruction and the oncological outcome. Between September 1999 and August 2010 31 patients (seven women and 24 men) were treated due to a primary malignant bone tumour or soft tissue sarcoma of the chest wall in two centres. Eight low-grade sarcomas were noted as well as 23 highly malignant sarcomas. The tumours originated from the sternum in six cases, from the ribs in 12 cases, from the soft tissues of the thoracic wall in 11 cases and from a vertebral body and the clavicle in one case each. In 26 cases wide resection margins were achieved, while four were intralesional and one was marginal. In all 31 cases the defect of the chest wall was reconstructed using mesh grafts. At a mean follow-up of 51 months 20 patients were without evidence of disease, three were alive with disease, seven patients had died and one patient was lost to follow-up. One recurrence was detected after wide resection of a malignant triton tumour. Primary malignant bone tumour or soft tissue sarcoma of the chest wall should be treated according to the same surgical oncological principles as established for the extremities. Reconstruction with mesh grafts and musculocutaneous flaps is associated with a low morbidity.

    2016-03-01

    Cytomegalovirus (CMV) is a highly complex pathogen which, despite modern prophylactic regimens, continues to affect a high proportion of thoracic organ transplant recipients. The symptomatic manifestations of CMV infection are compounded by adverse indirect effects induced by the multiple immunomodulatory actions of CMV. These include a higher risk of acute rejection, cardiac allograft vasculopathy after heart transplantation, and potentially bronchiolitis obliterans syndrome in lung transplant recipients, with a greater propensity for opportunistic secondary infections. Prophylaxis for CMV using antiviral agents (typically oral valganciclovir or intravenous ganciclovir) is now almost universal, at least in high-risk transplants (D+/R-). Even with extended prophylactic regimens, however, challenges remain. The CMV events can still occur despite antiviral prophylaxis, including late-onset infection or recurrent disease, and patients with ganciclovir-resistant CMV infection or who are intolerant to antiviral therapy require alternative strategies. The CMV immunoglobulin (CMVIG) and antiviral agents have complementary modes of action. High-titer CMVIG preparations provide passive CMV-specific immunity but also exert complex immunomodulatory properties which augment the antiviral effect of antiviral agents and offer the potential to suppress the indirect effects of CMV infection. This supplement discusses the available data concerning the immunological and clinical effects of CMVIG after heart or lung transplantation.

  5. Imaging after radiation therapy of thoracic tumors

    Ghaye, B.; Wanet, M.; El Hajjam, M.

    2016-01-01

    Radiation-induced lung disease (RILD) is frequent after therapeutic irradiation of thoracic malignancies. Many technique-, treatment-, tumor- and patient-related factors influence the degree of injury sustained by the lung after irradiation. Based on the time interval after the completion of the treatment RILD presents as early and late features characterized by inflammatory and fibrotic changes, respectively. They are usually confined to the radiation port. Though the typical pattern of RILD is easily recognized after conventional two-dimensional radiation therapy (RT), RILD may present with atypical patterns after more recent types of three or four-dimensional RT treatment. Three atypical patterns are reported: the modified conventional, the mass-like and the scar-like patterns. Knowledge of the various features and patterns of RILD is important for correct diagnosis and appropriate treatment. RILD should be differentiated from recurrent tumoral disease, infection and radiation-induced tumors. Due to RILD, the follow-up after RT may be difficult as response evaluation criteria in solid tumours (RECIST) criteria may be unreliable to assess tumor control particularly after stereotactic ablation RT (SABR). Long-term follow-up should be based on clinical examination and morphological and/or functional investigations including CT, PET-CT, pulmonary functional tests, MRI and PET-MRI. (authors)

    Purpose/Objective: Since 1980 electron arc irradiation of the postmastectomy chest wall has been the preferred technique for patients with advanced breast cancer at the our institution. Here we report the results of this technique in 150 consecutive patients from 1980 to 1994. Materials and Methods: Thoracic computerized tomography was used to determine internal mammary lymph node depth and chest wall thickness, and for computerized dosimetry calculations in all patients. Total doses of 45-50 Gy in 5 to 5 (1(2)) weeks were delivered to the chest wall and internal mammary lymph nodes via electron arc and, in most cases, supraclavicular and axillary nodes were treated with a matching photon field. Patients were assessed for acute and late radiation changes, local and distant control of disease, and survival. The 10 most recently treated patients were censored for disease progression, survival, and late effects calculations, thus giving a mean follow up of 49 months and a median of 33 months. All patients had advanced disease: T stages 1, 2, 3, and 4 represented 21%, 39%, 21% and 19% of the study population, with a mean number of positive axillary lymph nodes of 6.5 (0-29). Analysis was performed according to adjuvant status (no residual disease, n = 90), residual disease (positive margin, n = 15, and primary radiation, n = 2), or recurrent disease (n = 33). Results: Acute radiation reactions were generally mild and self limiting. 27% of patients developed moist desquamation, and 32% had brisk erythema. Actuarial 5 year local control, freedom from distant failure and overall survival was 91%, 64%, and 67% in the adjuvant group; 84%, 50%, and 53% in the residual disease group; and 63%, 34%, and 30% in the recurrent disease group, respectively. In univariate cox regressions, the number of positive lymph nodes was predictive for local failure in the adjuvant group (p<0.037). Chronic complications were minimal with 10% of patients having arm edema, 15% hyperpigmentation

    Background and purpose: Since 1980 electron arc irradiation of the postmastectomy chest wall has been the preferred technique for patients with advanced breast cancer at our institution. Here we report the results of this technique in 140 consecutive patients treated from 1980 to 1993. Materials and Methods: Thoracic computerized tomography was used to determine internal mammary lymph node depth and chest wall thickness, and for computerized dosimetry calculations. Total doses of 45-50 Gy in 5 to 5 (1(2)) weeks were delivered to the chest wall and internal mammary lymph nodes via electron arc and, in most cases, supraclavicular and axillary nodes were treated with a matching photon field. Patients were assessed for acute and late radiation changes, local and distant control of disease, and survival. Patients had a minimum follow-up of 1 year after completion of radiation treatment, and a mean follow up interval of 49 months and a median of 33 months. All patients had advanced disease: T stages 1, 2, 3, and 4 represented 21%, 39%, 21% and 19% of the study population, with a mean number of positive axillary lymph nodes of 6.5 (range, 0-29). Analysis was performed according to adjuvant status (no residual disease, n=90), residual disease (positive margin, n=15, and primary radiation, n=2), or recurrent disease (n=33). Results: Acute radiation reactions were generally mild and self limiting. A total of 26% of patients developed moist desquamation, and 32% had brisk erythema. Actuarial 5 year local-regional control, freedom from distant failure, and cause-specific survival was 91%, 64%, and 75% in the adjuvant group; 84%, 50%, and 53% in the residual disease group; and 63%, 34%, and 32% in the recurrent disease group, respectively. In univariate Cox regressions, the number of positive lymph nodes was predictive for local failure in the adjuvant group (P=0.037).

    Gossypiboma is an inflammatory pseudomass formed by a retained surgical sponge or gauze with reactive tissue after surgery. Gossypiboma has been reported most frequently after abdominal or thoracic surgery. As such, gossypiboma following brain surgery is very rare. We report a case of gossypiboma mimicking tumor recurrence in the brain after a craniotomy and surgical excision of a low grade astrocytoma.

    Full Text Available This paper reports the clinical, bacteriological and pathological findings of a thoracic aortic aneurysm in a four-year-old Anglo-Nubian goat buck, related to a framework of visceral caseous lymphadenitis. General clinical examination showed heart rate of 75 beats per minute, respiratory rate of 20 movements per minute and ruminal movements of four movements per minute. Superficial lymph nodes were normal upon palpation. Rectal temperature was slightly high (40.5°C. Blood test showed an intense leukocytosis (54,000/µL, characterized by strong neutrophil shift to the left. At necropsy, a large blood clot was detected in the thoracic cavity. The thickening of the myocardium and dilatation of the aorta in the thoracic portion, presenting a saculiform format was also observed. A large number of abscesses were disseminated in the media and intima layers of aorta. The aorta lumen obstruction by arterial plaques consisting of inflammatory infiltrate, predominantly neutrophilic was also detected. Abscesses were found spread in turbinate, rumen, reticulum, kidneys, liver, spleen, testicles and aorta wall. The microbiological exam of exudate confirmed Corynebacterium pseudotuberculosis as the causal agent.

    Postoperative pain is thought to be the single most important factor leading to ineffective ventilation and impaired secretion clearance after thoracic trauma. Effective pain relief can be provided by thoracic epidural analgesia but may have side effects or contraindications. Paravertebral block is an effective alternative method without the side effects of a thoracic epidural. We did this study to compare efficacy of thoracic epidural and paravertebral block in providing analgesia to thoracic trauma patients. After ethical clearance, 50 patients who had thoracic trauma were randomized into two groups. One was a thoracic epidural group (25), and second was a paravertebral group (25). Both groups received 10 ml of bolus of plain 0.125% bupivacaine and a continuous infusion of 0.25% bupivacaine at the rate of 0.1 ml/kg/h for 24 h. Assessment of pain, hemodynamic parameters, and spirometric measurements of pulmonary function were done before and after procedure. Visual analog scale (VAS) scores were accepted as main outcome of the study and taken for power analysis. There was significant decrease in postoperative pain in both the groups as measured by VAS score. However, the degree of pain relief between the groups was comparable. There was a significant improvement in pulmonary function tests in both the groups post-procedure. The change in amount of inflammatory markers between both the groups was not significantly different. Paravertebral block for analgesia is comparable to thoracic epidural in thoracic trauma patients and is associated with fewer side effects.

    To analyze the initial thoracic involvement by CT in a consecutive series of patients with lymphoma. A retrospective analysis was made of thoracic CT studies made at the time of diagnosis of 259 patients with lymphoma. Mediastinal pulmonary, pleural, pericardial and chest wall involvement was assessed by CT. Of 259 patients (129 men y 130 women), 56 had Hodgkin's disease (HD) and 203 had non-Hodgkin lymphoma (NHL). Forty-two percent (42.5%, 110/259) of the patients had chest involvement on CT: 33 of 56 patients with HD (58.9%) and 77 of 203 patients with NHL (37.9%). All the patients with thoracic HD and 71.4% of patients with thoracic NHL, had mediastinal lymph node involvement. of the patients with thoracic involvement 12.1% (4/33) of the patient with HD and 23.3% (18/77) of the patients with NHL had pulmonary involvement. Thoracic involvement on CT was more frequent in HD. Mediastinal lymph node involvement was the most common finding fundamentally in HD. Pulmonary disease always occurred in the presence of mediastinal lymph node involvement in HD but could occur as an isolated finding in NHL. (Author) 24 refs.

    A 55-year-old man with malignant pleural mesothelioma underwent multimodality treatment comprising induction chemotherapy followed by extrapleural pneumonectomy and radiation therapy. After 2.5 years, focal recurrence occurred, with computed tomography revealing a tumor in the left cardiophrenic angle. Surgery was considered a problem for the patient because of the previous extrapleural pneumonectomy and difficult tumor location. Radiofrequency ablation was thus performed; the course was uneventful, and there was no recurrence. Radiofrequency ablation should be considered an option to treat recurrence of malignant pleural mesothelioma. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    1988-01-01

    The authors reviewed CT scans and supine chest X-ray of 47 patients affected by severe thoracic trauma, examined in 1985-86. The sensibility of the two methodologies in the assessment of pneumothorax was compared. CT detected 25 pneumothorax, whereas supine chest X-ray allowed a diagnosis in 18 cases only. In 8 of the latter (44.4%) the diagnosis was made possible by the presence of indirect signs of pneumothorax only - the most frequent being the deep sulcus sign. The characterization of pneumothorax is important especially in the patients who need to be treated with mechanical ventilation therapy, or who are to undergo surgery in total anaesthesia

    2013-10-01

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

    Birt-Hogg-Dubé syndrome manifests in the thorax as lung cysts. The purpose of this article is to describe the CT characteristics of cysts in patients with Birt-Hogg-Dubé syndrome and to note other thoracic findings. The thoracic CT examinations of 17 patients with Birt-Hogg-Dubé syndrome were reviewed retrospectively for the presence, anatomic distribution (upper lung predominant, lower lung predominant, or diffuse), extent (size, number), and morphology (shape, wall thickness) of cysts. Any additional thoracic findings were also noted. The study population consisted of 13 women (76%) and four men (24%) with a mean age of 50.2 ±15.2 years. Two patients (12%) had normal findings on CT. Fifteen patients had cystic lung disease, all of whom had more than one cyst. Most patients had bilateral (13/15, 87%) and lower lung-predominant cysts (13/15, 87%). The cysts varied in size from 0.2 to 7.8 cm. The largest cysts were located in the lower lobes of 14 of 15 patients (93%). Of the nine patients with large cysts, most had at least one multiseptated cyst (7/9, 78%). Five of 15 patients (33%) had more than 20 cysts. Cyst shape varied among the 15 patients and also within individual patients (10/15, 67%) ranging from round to oval, lentiform, and multiseptated. Cysts showed no central or peripheral predominance. Discrete thin-walled cysts in patients with Birt-Hogg-Dubé syndrome are more numerous and larger in the lower lobes and vary in size and shape. Large lung cysts are frequently multiseptated. These features may aid in differentiating Birt-Hogg-Dubé syndrome from other more common cystic lung diseases.

    The chest PA examination is one of the single most performed studies in radiology today. It can provide a wealth of information in a single examination. As in many other areas of radiology there is a conflict between high contrast, which enables subtle structures to be visualized, and wide latitude, which allows all areas of interest in the chest to be displayed in a single image. In order to optimize the design of receptor systems it is useful to establish and understand the latitude required for thoracic imaging. We have measured the distributions of x-ray transmittance within the lungs, heart, and abdomen for a population of 868 out-patients. The measurements were made with a resolution element approximately 2 X 2 cm, at a single x-ray beam quality, and with a low-scatter slot-beam geometry. Under these conditions, the required receptor latitude for capturing each area of interest in the thorax is derived as a function of body habitus. To capture all three regions the required receptor latitude for the PA examination varies from 11:1 to 81:1 with increasing patient size. The implications of these results for thoracic image-receptor design is discussed.

    Schwannomas are benign, slow growing nerve sheath tumours of Schwann cell origin. They predominantly are known to involve the head, neck and the flexor surfaces of the extremities, retroperitoneum and the posterior spinal roots. The chest wall is a relatively uncommon location for a schwannoma, the vast majority of which are intra-thoracic, which are usually located in the posterior mediastinum and bulge into the thoracic cavity. Schwannomas arising from the lateral chest wall are relatively uncommon (chest wall i.e. with an intra-thoracic and extra-thoracic component, is extraordinarily rare and to the best of our knowledge only one case has been reported prior. We report possibly the second case of a dumbbell shaped lateral chest wall schwannoma in a 33-year-old female patient which masquandered as a case of soft tissue sarcoma.

    The frequently encountered thoracic trauma in surgical emergencies is a major cause of mortality and morbidity. Eighty percent of thoracic trauma can be managed by simple insertion of tube thoracostomy. Though guidelines for insertion are comprehensively explained in literature, an ideal algorithm for discontinuation is not available. A standard and safe defined protocol would eliminate hesitancy in confident removal among general surgeons. The objective of this study was to determine role of clamping trial prior to removal in terms of frequency of recurrent pneumothorax. Methods: This study was conducted in department of Surgery Combined military hospital/Military Hospital Rawalpindi from April 2013 to March 2014. Total 180 patients with blunt or penetrating thoracic trauma were included in the study. Chest tube (28-36 Fr) was inserted in Trauma centre under strict asepsis. Tubes were then connected to under water seal for minimum six hours. Patients were randomly divided in two equal groups (90 in each). In Group A, Clamping trial was given before attempting removal while in Group B, tube was removed immediately without clamping trial. Patients of both groups were observed two hourly for development of recurrent pneumothorax. Data was analysed using SPSS-18. Results: The comparison of frequency of recurrent pneumothorax in Group A (9 patients, 10%) and in Group B (4 patients, 4.5%) was not found to be statistically significant. (p-value 2.073). Conclusion: Clamping trial is unnecessary prior to removal of tube thoracostomy in blunt and penetrating non-cardiac thoracic trauma in terms of recurrent pneumothorax. (author)

    Full Text Available Epigastric heteropagus (EH refers to asymmetrically conjoined twins in whom an incomplete parasite is attached to the autosite's epigastric region from the xiphisternum to the umbilicus. We herein report an extremely rare case of EH in which unexpected rapid recurrence occurred 22 months after excision of the parasite. The recurrent mass comprised the intestinal wall with peristalsis-like movement, urogenital tissues, and hepatic tissue of the parasite. The recurrence was caused by a remnant of the parasite that extended from the autosite's xiphisternum to intra-abdominal cavity.

    Thoracic outlet syndrome (TOS) is a condition arising from compression of the subclavian vessels and/or brachial plexus. Many factors or diseases may cause compression of the neurovascular bundle at the thoracic outlet. We describe the case of a 41-year-old woman with TOS who presented with vascular venous symptoms. Chest computed tomography (CT) scan showed a cystic mass at the level of cervico-thoracic junction, located between the left subclavian artery and vein, which appeared compressed. The cystic mass was removed through a cervical approach and it was found to be a cyst arising from the thoracic duct compressing and anteriorly dislocating the left subclavian vein. After surgery symptoms promptly disappeared.

It is a significant cause of mortality. Multidetector computed tomography (MDCT has been an increasingly used method to evaluate chest trauma because of its high success in detecting tissue and organ injuries. Herein, we aimed to present MDCT findings in patients with blunt and penetrating chest trauma admitted to our department. Methods: A total of 240 patients admitted to the emergency department of our hospital between April 2012 and July 2013 with a diagnosis of chest trauma who underwent MDCT evaluations were included. Most of the patients were male (83.3% and victims of a blunt chest trauma. The images were analyzed with respect to the presence of fractures of bony structures, hemothorax, pneumothorax, mediastinal organ injury, and pulmonary and vascular injuries. Results: MDCT images of the 240 patients yielded a prevalence of 41.7% rib fractures, 11.2% scapular fractures, and 7.5% clavicle fractures. The prevalence of thoracic vertebral fracture was 13.8% and that of sternal fracture was 3.8%. The prevalence of hemothorax, pneumothorax, pneumomediastinum, and subcutaneous emphysema was 34.6%, 62.1%, 9.6%, and 35.4%, respectively. The prevalence of rib, clavicle, and thoracic vertebral fractures and pulmonary contusion was higher in the blunt trauma group, whereas the prevalence of hemothorax, subcutaneous emphysema, diaphragmatic injury, and other vascular lacerations was significantly higher in the penetrating trauma group than in the blunt trauma group (p<0.05. Conclusion: MDCT images may yield a high prevalence of fracture of bony structures, soft tissue lacerations, and vascular lesions, which should be well understood by

    Thoracic aortic rupture and aortopulmonary fistulation are rare conditions in horses. It mainly affects Friesian horses. Intrinsic differences in biomechanical properties of the aortic wall might predispose this breed. The biomechanical and biochemical properties of the thoracic aorta were characterized in warmblood horses, unaffected Friesian horses and Friesians with aortic rupture in an attempt to unravel the underlying pathogenesis of aortic rupture in Friesian horses. Samples of the thoracic aorta at the ligamentum arteriosum (LA), mid thoracic aorta (T1) and distal thoracic aorta (T2) were obtained from Friesian horses with aortic rupture (A), nonaffected Friesian (NA) and warmblood horses (WB). The biomechanical properties of these samples were determined using uniaxial tensile and rupture assays. The percentages of collagen and elastin (mg/mg dry weight) were quantified. Data revealed no significant biomechanical nor biochemical differences among the different groups of horses. The distal thoracic aorta displayed an increased stiffness associated with a higher collagen percentage in this area and a higher load-bearing capacity compared to the more proximal segments. Our findings match reported findings in other animal species. Study results did not provide evidence that the predisposition of the Friesian horse breed for aortic rupture can be attributed to altered biomechanical properties of the aortic wall.

  11. The value of thoracic and abdominal computerized tomography in pediatric patients

    International Nuclear Information System (INIS)

    Tschaeppeler, H.

    1983-01-01

    Today CT of the pediatric chest and abdomen is an accepted and established diagnostic modality. Detection of pulmonary metastases and the staging of malignant lymphoma of the mediastinum are main indications for thoracic CT, whereas in other neoplastic mediastinal or thoracic wall lesions, which are much rarer, CT is complementary to very valuable conventional examinations. However the cross-sectional display free of superposition and the possibility of density-measurement are outstanding advantages for both thoracic and abdominal CT. Abdominal extension of malignant lymphoma is accurately determined; pretherapeutic staging and followup evaluation of primary retroperitoneal, hepatic and pelvic neoplasms are further indications in selected patients. After blunt abdominal trauma CT does not only demonstrate the extent of parenchymatous laceration, but also provides exact assessment of perfusion and/or function of an organ. (Author)

    Purpose: To develop and validate a semiautomatic segmentation method for thoracic cavity volumetry and mediastinum fat quantification of patients with chronic obstructive pulmonary disease. Methods: The thoracic cavity region was separated by segmenting multiorgans, namely, the rib, lung, heart, and diaphragm. To encompass various lung disease-induced variations, the inner thoracic wall and diaphragm were modeled by using a three-dimensional surface-fitting method. To improve the accuracy of the diaphragm surface model, the heart and its surrounding tissue were segmented by a two-stage level set method using a shape prior. To assess the accuracy of the proposed algorithm, the algorithm results of 50 patients were compared to the manual segmentation results of two experts with more than 5 years of experience (these manual results were confirmed by an expert thoracic radiologist). The proposed method was also compared to three state-of-the-art segmentation methods. The metrics used to evaluate segmentation accuracy were volumetric overlap ratio (VOR), false positive ratio on VOR (FPRV), false negative ratio on VOR (FNRV), average symmetric absolute surface distance (ASASD), average symmetric squared surface distance (ASSSD), and maximum symmetric surface distance (MSSD). Results: In terms of thoracic cavity volumetry, the mean ± SD VOR, FPRV, and FNRV of the proposed method were (98.17 ± 0.84)%, (0.49 ± 0.23)%, and (1.34 ± 0.83)%, respectively. The ASASD, ASSSD, and MSSD for the thoracic wall were 0.28 ± 0.12, 1.28 ± 0.53, and 23.91 ± 7.64 mm, respectively. The ASASD, ASSSD, and MSSD for the diaphragm surface were 1.73 ± 0.91, 3.92 ± 1.68, and 27.80 ± 10.63 mm, respectively. The proposed method performed significantly better than the other three methods in terms of VOR, ASASD, and ASSSD. Conclusions: The proposed semiautomatic thoracic cavity segmentation method, which extracts multiple organs (namely, the rib, thoracic wall, diaphragm, and heart

    PurposeThis study was designed to investigate thoracic duct collateral leakage and the supply route of lymphatic fluid by lymphangiography and transcatheter thoracic ductography and to evaluate the results of embolization for thoracic duct collateral leakage performed to cut off this supply route.MethodsData were retrospectively collected from five patients who underwent embolization for thoracic duct collateral leakage in persistent high-output chylothorax after thoracic surgery. Extravasation of lipiodol at the ruptured thoracic duct collaterals was confirmed in all patients on lymphangiography. Transcatheter thoracic ductography was used to identify extravasation of iodinated contrast agent and to identify communication between the thoracic duct and leakage site. Thoracic duct embolization (TDE) was performed using the percutaneous transabdominal approach to cut off the supply route using N-butyl cyanoacrylate (NBCA) mixed with lipiodol (1:5–1:20).ResultsClinical success (drainage volume ≤10 mL/kg/day within 7 days after TDE) was achieved in all patients. The collateral routes developed as consequence of surgical thoracic duct ligation. In three patients, NBCA-Lipiodol reached the leakage site through direct communication between the thoracic duct and the ruptured lymphatic duct. In the other two patients, direct communication and extravasation was not detected on thoracic ductography, and NBCA-Lipiodol did not reach the leakage site. However, NBCA-Lipiodol did reach the cisterna chyli, lumbar trunks, and some collateral routes via the cisterna chyli or lumbar lymphatics. As a result, leakage was stopped.ConclusionsTDE was effective for the management of leakage of the collaterals in high-output chylothorax after thoracic surgery.

    Thoracotomy as surgical approach for esophageal atresia treatment entails the risk of deformation of the rib cage and consequently secondary thoracogenic scoliosis. The aim of our study was to assess these thoracic wall anomalies on a large national cohort and search for factors influencing this morbidity. Pediatric surgery departments from our national network were asked to send recent thoracic X-ray and operative reports for patients born between 2008 and 2010 with esophageal atresia. The X-rays were read in a double-blind manner to detect costal and vertebral anomalies. Among 322 inclusions from 32 centers, 110 (34.2%) X-rays were normal and 25 (7.7%) displayed thoracic malformations, including 14 hemivertebrae. We found 187 (58.1%) sequelae of surgery, including 85 costal hypoplasia, 47 other types of costal anomalies, 46 intercostal space anomalies, 21 costal fusions and 12 scoliosis, with some patients suffering from several lesions. The rate of patients with these sequelae was not influenced by age at intervention, weight at birth, type of atresia, number of thoracotomy or size of the center. The rate of sequelae was higher following a classical thoracotomy (59.1%), whatever the way that thoracotomy was performed, compared to nonconverted thoracoscopy (22.2%; p=0.04). About 60 % of the patients suffered from a thoracic wall morbidity caused by the thoracotomy performed as part of surgical treatment of esophageal atresia. Minimally invasive techniques reduced thoracic wall morbidity. Further studies should be carried out to assess the potential benefit of minimally invasive approaches to patient pulmonary functions and on the occurrence of thoracogenic scoliosis in adulthood.

    Thoracic sympathectomy is considered the most effective method to treat palmar hyperhidrosis. We developed a novel approach for thoracic sympathectomy in patients with palmar hyperhidrosis through the umbilicus, using an ultrathin gastroscope. The aim of this study was to evaluate the continuing efficacy and patient satisfaction of this innovative surgery. All procedures were performed under general anesthesia and the patients were intubated with a dual-lumen endotracheal tube. After a 5-mm umbilical incision, the muscular parts of the diaphragmatic dome were incised with a needle-knife and the nasal gastroscope was advanced into the thoracic cavity. The sympathetic chain was identified at the desired thoracic level and ablated with hot biopsy forceps. All patients were followed up for at least 1 year after the procedure through clinic visits or telephone/e-mail interviews. From April 2010 to August 2011, a total of 35 patients underwent a transumbilical thoracic sympathectomy. Fifty-seven percent were male patients, with a mean age of 21.2 years (range, 16-33 years). The success rate after 12 months was 97.1% (34 of 35) for isolated palmar hyperhidrosis and 72.2% (13 of 18) for axillary hyperhidrosis. Compensatory sweating was reported in 28.6% of patients at the 1-year follow-up evaluation. There was no mortality, no diaphragmatic hernia, and no Horner syndrome was observed. Quality of life related to hyperhidrosis improved substantially in 27 (77.1%) patients, and improved in 4 (11.4%) patients at 12 months after surgery. A total of 94.3% of patients were satisfied with the excellent cosmetic results of the surgical incision. Transumbilical thoracic sympathectomy is an efficacious alternative to the conventional approach. This technique avoided the chronic pain and chest wall paresthesia associated with the chest incision. In addition, this novel procedure afforded maximum cosmetic benefits.

    Full Text Available High speed vehicles, drug abuse, alcohol and easy availability of handguns are the main reasons of increasing number of trauma especially thoracic trauma. Anaesthesiologist plays an important role in the management of extensive thoracic trauma. Thoracic trauma, penetrating or blunt, may cause damage to organs suspended in thorax viz. pleura, lungs, heart, great vessels, trachea and oesophagus. It may lead to pneumothorax, cardiac tamponade or life threatening haemorrhage. With aggressive care and management of these factors, majority of patients can survive and return to normal life.

    Thoracic outlet syndrome occurs due to compression of the neurovascular structures as they exit the thorax. Subclavian arterial compression is usually due to a cervical rib, and is rarely associated with thromboembolic stroke. The mechanism of cerebral embolisation associated with the thoracic outlet syndrome is poorly understood, but may be due to retrograde propagation of thrombus or transient retrograde flow within the subclavian artery exacerbated by arm abduction. We report an illustrative patient and review the clinical features, imaging findings and management of stroke associated with thoracic outlet syndrome. Copyright © 2013 Elsevier Ltd.

  1. Pain recurrence after shaving of rectovaginal endometriosis

    DEFF Research Database (Denmark)

    Heide, Mathias Gottschalck; Forman, Axel

    Background: Surgical treatment of rectovaginal endometriosis varies from shaving of the nodule off the rectal wall without perforation, over discoid excision to routine rectal resection. Of these methods, shaving involves the lowest rate of serious complications but leaves endometriosis tissue...... on the bowel with risk of recurrence. This could motivate a change into more radical surgery. In the present study we therefore assessed recurrence of pain after shaving of rectovaginal endometriosis performed 2001-2009. Methods: Retrospective follow-up study. Questionnaires were sent to 212 women of whom 174...... OCs and gestagen IUD showed a trend towards a protective effect against menstrual pain (p=0.06). There was found no significant association between recurrence of pain and anterior rectal wall involvement. Conclusion: Shaving of rectovaginal endometriosis shows a high risk of postoperative pain...

  2. Thoracic disc herniation: Surgical treatment.

    Science.gov (United States)

    Court, C; Mansour, E; Bouthors, C

    2018-02-01

    Thoracic disc herniation is rare and mainly occurs between T8 and L1. The herniation is calcified in 40% of cases and is labeled as giant when it occupies more than 40% of the spinal canal. A surgical procedure is indicated when the patient has severe back pain, stubborn intercostal neuralgia or neurological deficits. Selection of the surgical approach is essential. Mid-line calcified hernias are approached from a transthoracic incision, while lateralized soft hernias can be approached from a posterolateral incision. The complication rate for transthoracic approaches is higher than that of posterolateral approaches; however, the former are performed in more complex herniation cases. The thoracoscopic approach is less invasive but has a lengthy learning curve. Retropleural mini-thoracotomy is a potential compromise solution. Fusion is recommended in cases of multilevel herniation, herniation in the context of Scheuermann's disease, when more than 50% bone is resected from the vertebral body, in patients with preoperative back pain or herniation at the thoracolumbar junction. Along with complications specific to the surgical approach, the surgical risks are neurological worsening, dural breach and subarachnoid-pleural fistulas. Giant calcified herniated discs are the largest contributor to myelopathy, intradural extension and postoperative complications. Some of the technical means that can be used to prevent complications are explored, along with how to address these complications. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    2017-01-01

    Abstract Rationale: Splenosis is the development of one or more heterotopic splenic tissue autoimplants following rupture of the spleen and remains mostly asymptomatic. Patient concerns: We report a case of a 50-year old post-traumatic splenectomized man admitted for a left side community acquired pneumonia resistant to antibiotics. Diagnoses: The diagnosis of intrathoracic ectopic spleen was suspected because of the history of spleen trauma with diaphragm rupture and the absence of Howell-Jolly bodies. Interventions: Technetium (Tc)-99m colloid scintigraphy SPECT, fused with CT scan showed an intense radionuclide uptake on hyper vascularized masses without any additional pathologic uptake and confirmed the diagnosis of thoracic splenosis. Outcomes: Despite any lifelong penicillin prophylaxis, he had no history of infections eight years after the diagnosis. Lessons: Physician must be aware of this differential diagnosis and of its consequences. Depending on its size and location, it may lead to incorrect diagnosis (tumor, empyema, abscess ...), treatment and invasive procedures while the diagnosis of splenosis only relies upon imaging studies associated with functionnal study of the uptake of particles or cells.

    We now have access to a large library of publications validating transparietal thoracic echography in various clinical situations. Parietal lesions, including osteolysis, can be detected and biopsied during the thoracic ultrasound (TUS) examination. To evaluate the parietal extension of lung cancers, TUS has proved superior to tomodensitometry. Pleural effusions can be easily diagnosed and aspirated. Pneumothoraces can be detected using well defined lung artifacts with a high frequency probe....

    While open window thoracostomy (OWT) is a safe procedure and is indicated in patients who have thoracic empyema either with or without a bronchopleural fistula, it may prolong the hospital stay. We retrospectively analyzed the relationship between the etiology of thoracic empyema and the open window interval (OWI). Between January 1986 and May 1997, 53 patients resistant to conventional therapy underwent OWT for thoracic empyema at the Department of Surgery of the National Minami-Fukuoka Chest Hospital. The patients were classified into five groups based on the etiological findings of thoracic empyema. 44 patients also underwent closure of the window until June 1999. The average OWI was 180.4 +/- 51.9 (mean +/- SE) days for postoperative empyemas in lung cancer, 128.0 +/- 32.1 days for bacterial nontuberculous empyemas, 189.6 +/- 24.1 days for fungal empyemas, 365.8 +/- 201 days for empyemas caused by atypical mycobacteria and 322.0 +/- 58.7 days for tuberculous empyemas. There was no evidence that the OWI was related to either sex, age, etiology of thoracic empyemas, performance status, the existence of bronchopleural fistulae, complications of diabetes mellitus or preoperative malnutrition status in multivariable models. 5 patients underwent a second OWT because of recurrence of empyema. Mortality rate was 7.5%. There was no relationship between clinical factors including nutritional assessment and OWI. OWT generally is a safe and effective procedure for thoracic empyema resisting to conventional therapy except that it can make an extended hospital stay necessary. Copyright 2001 S. Karger AG, Basel

    Radiotherapy is a cancer treatment intended to deposit the entire prescribed dose homogeneously into a target volume in order to eliminate the tumor and to spare the surrounding healthy tissues. This paper aimed to provide a dosimetric comparison between the treatment planning system (TPS) ECLIPSE from Varian Medical Systems and the internal dosimetric measurements in a breast phantom. The methodology consisted in performing a 3D conformal radiotherapy planning with two tangential opposite parallel fields applied to the synthetic breast in a thoracic phantom. The irradiation was reproduced in the Varian Linear accelerator, model SL - 20 Precise, 6 MV energy. EBT2 Radiochromic films, placed into the glandular equivalent tissue of the breast, were used to measure the spatial dose distribution. The absorbed dose was compared to those values predicted by the treatment planning system; besides, the dosimetric uncertainties were analyzed. The modal absorbed dose was in agreement with the prescribed value of 180 cGy, although few high dose points between 180 and 220 cGy were detected. The findings suggested a non-uniform dose distribution in the glandular tissue of the synthetic breast, similar to those found in the TPS, associated with the irregular anatomic breast shape and presence of inhomogeneities next to the thoracic wall generated by the low lung density.

    Pulmonary metastases are common in osteosarcoma and the most common appearance is of multiple well-defined nodules in the lung parenchyma. However, a variety of atypical locations and presentations of osteosarcoma metastasis can occur in the thorax. We present a review of the thoracic CT findings in 16 patients with histopathologically confirmed osteosarcoma with unusual thoracic manifestations. The 16 patients were selected out of a total 136 patients who received a chest CT scan for osteosarcoma during a period of 3 years in a tertiary care hospital. Unusual imaging findings included a solitary large ossified lung mass, ossified mediastinal and hilar lymph nodes, an esophagomediastinal fistula, lymphangitic carcinomatosis, pulmonary artery tumor emboli, a solitary large pleural deposit along the major fissure, multiple pleural deposits, diffuse pleural calcification, pneumothorax, diaphragmatic deposits, an isolated chest wall deposit without lung involvement, and primary osteosarcoma of the rib. Our findings of lymphangitic carcinomatosis in a living patient as well as calcified mediastinal lymphadenopathy leading to esophageal fistula are unique in the literature, and there are only a few case reports of our other findings.

    Full Text Available This review article covers the spectrum of congenital thoracic wall deformities along with their historical background. Willital′s classification divides these deformities into 11 types - funnel chest (4 types, pigeon chest (4 types, and combination of funnel and pigeon chest, chest wall aplasia and cleft sternum. Records of patients at our center comprised 90% depression deformities, 6% protrusion deformities, 3% combined depression-protrusion deformities and 1% other forms. Mild forms of abnormalities warrant the wait- and-watch approach during the first 4-5 years. The deformities manifest primarily during the pubertal spurt often with rapid progression with subjective complaints like dyspnea, cardiac dysthesia, limited work performance and secondary changes. Operative correction in young adults is more favorable in mild cases. The Willital technique has been the standard technique for the correction of pectus excavatum, pectus carinatum and other combined forms of deformities at our center with excellent long term results. The Nuss procedure and the Pectus Less Invasive Extrapleural Repair (PLIER technique for pectus excavatum and pectus carinatum have also been described in this article. Surgical correction for Poland′s syndrome is reserved for patients with severe aplasia of the ribs with major depression deformity. Sternal defects including various types of ectopia cordis are discussed. Even after surgical correction, there is significant reduction in the total capacity and inspiratory vital capacity of the lungs, probably a result of the decreased compliance of the chest wall. However, the efficiency of breathing at maximal exercise improves significantly after operation.

    Thoracic outlet syndrome is caused by compression of the neurovascular bundle as it passes from the upper thorax to the axilla. The neurovascular bundle can be compressed by bony structures such as the first rib, cervical ribs or bone tubercles, or from soft-tissue abnormalities like a fibrous band, muscle hypertrophy or space-occupying lesion. Thoracic outlet syndrome commonly affects young adults but can be seen in the pediatric age group, especially in older children. Diagnosis is based on a holistic approach encompassing clinical features, physical examination findings including those triggered by various maneuvers, electromyography, nerve conduction studies and imaging. Imaging is performed to confirm the diagnosis, exclude mimics and classify thoracic outlet syndrome into neurogenic, arterial, venous or mixed causes. MRI and MR angiography are useful in this process. A complete MRI examination for suspected thoracic outlet syndrome should include the assessment of anatomy and any abnormalities using routine sequences, vessel assessment with the arms in adduction by MR angiography and assessment of dynamic compression of vessels with abduction of the arms. The purpose of this paper is to describe the anatomy of the thoracic outlet, causes of thoracic outlet syndrome, the MR imaging techniques used in its diagnosis and the principles of image interpretation.

    Danguilan, Jose Luis J

    2016-08-01

    Thoracic surgery in the Philippines followed the development of thoracic surgery in the United States and Europe. With better understanding of the physiology of the open chest and refinements in thoracic anesthetic and surgical approaches, Filipino surgeons began performing thoracoplasties, then lung resections for pulmonary tuberculosis and later for lung cancer in specialty hospitals dealing with pulmonary diseases-first at the Quezon Institute (QI) and presently at the Lung Center of the Philippines although some university and private hospitals made occasional forays into the chest. Esophageal surgery began its early attempts during the post-World War II era at the Philippine General Hospital (PGH), a university hospital affiliated with the University of the Philippines. With the introduction of minimally invasive thoracic surgical approaches, Filipino thoracic surgeons have managed to keep up with their Asian counterparts although the problems of financial reimbursement typical of a developing country remain. The need for creative innovative approaches of a focused multidisciplinary team will advance the boundaries of thoracic surgery in the Philippines.

    Thoracic outlet syndrome is caused by compression of the neurovascular bundle as it passes from the upper thorax to the axilla. The neurovascular bundle can be compressed by bony structures such as the first rib, cervical ribs or bone tubercles, or from soft-tissue abnormalities like a fibrous band, muscle hypertrophy or space-occupying lesion. Thoracic outlet syndrome commonly affects young adults but can be seen in the pediatric age group, especially in older children. Diagnosis is based on a holistic approach encompassing clinical features, physical examination findings including those triggered by various maneuvers, electromyography, nerve conduction studies and imaging. Imaging is performed to confirm the diagnosis, exclude mimics and classify thoracic outlet syndrome into neurogenic, arterial, venous or mixed causes. MRI and MR angiography are useful in this process. A complete MRI examination for suspected thoracic outlet syndrome should include the assessment of anatomy and any abnormalities using routine sequences, vessel assessment with the arms in adduction by MR angiography and assessment of dynamic compression of vessels with abduction of the arms. The purpose of this paper is to describe the anatomy of the thoracic outlet, causes of thoracic outlet syndrome, the MR imaging techniques used in its diagnosis and the principles of image interpretation.

    Malignant lymphomas belong to the most important malignant diseases in western countries with an increasing incidence of Non-Hodgkin lymphoma. The thorax is the location of primary manifestation especially in patients with Hodgkin's disease. Progression of disease and therapy associated complications are frequently located in the chest. Based on morphological imaging criteria the two types of lymphoma cannot be differentiated, helpful for differentiation is, however, the way of disease spread. Primary and secondary thoracic lymphoma represent a diagnostic challenge in radiology: the patterns are variable in radiography as well as in computed tomography and alter under therapy. Radiological studies, especially CT, are an integral part of the staging process. MRI is considered advantageous for chest wall disease. PET as functional imaging technique has its proven role for staging of high grade lymphomas, the combination of functional and morphological information provided by PET-CT will become the first diagnostic standard in the future.

    Raynaud's disease is a disorder that is characterized by attacks of pain, cyanosis, redness, and numbness in the upper extremities caused by vasospasm of digital arteries due to cold or emotional stress. We aimed at demonstrating our experiences with endoscopic thoracic sympathectomy (ETS) in the treatment of Raynaud's disease. From 48 patients who underwent ETS for various reasons at our department between January 2014 and January 2015, we reviewed 9 patients with Raynaud's disease (18.7%) with respect to their demographic characteristics such as gender and age, postoperative complications, short-term results, side effects, recurrence of symptoms, and long-terms results. The symptoms and findings reappeared and the number and dosage of the drugs used returned to their preoperative levels in 66.6% of the patients at month 6, and in all patients except 1 at the end of the 1st year. ETS should be considered an ultimate choice for patients with Raynaud's disease who have treatment-resistant severe symptoms and serious complications, disturbed social and daily lives, and impaired quality of life, and all patients should be properly informed before the surgery about the possibility of a high rate of recurrence.

    Objective Large vessel vasculitides (LVV) are a group of autoimmune diseases characterized by injury to and anatomic modifications of large vessels, including the aorta and its branch vessels. Disease etiology is unknown. This study was undertaken to identify antigen targets within affected vessel walls in aortic root, ascending aorta, and aortic arch surgical specimens from patients with LVV, including giant cell arteritis, Takayasu arteritis, and isolated focal aortitis. Methods Thoracic aortic aneurysm specimens and autologous blood were acquired from consenting patients who underwent aorta reconstruction procedures. Aorta proteins were extracted from both patients with LVV and age-, race-, and sex-matched disease controls with noninflammatory aneurysms. A total of 108 serum samples from patients with LVV, matched controls, and controls with antinuclear antibodies, different forms of vasculitis, or sepsis were tested. Results Evaluation of 108 serum samples and 22 aortic tissue specimens showed that 78% of patients with LVV produced antibodies to 14-3-3 proteins in the aortic wall (93.7% specificity), whereas controls were less likely to do so (6.7% produced antibodies). LVV patient sera contained autoantibody sufficient to immunoprecipitate 14-3-3 protein(s) from aortic lysates. Three of 7 isoforms of 14-3-3 were found to be up-regulated in aorta specimens from patients with LVV, and 2 isoforms (ε and ζ) were found to be antigenic in LVV. Conclusion This is the first study to use sterile, snap-frozen thoracic aorta biopsy specimens to identify autoantigens in LVV. Our findings indicate that 78% of patients with LVV have antibody reactivity to 14-3-3 protein(s). The precise role of these antibodies and 14-3-3 proteins in LVV pathogenesis deserves further study.

  19. Treatment of locally recurrent rectal cancer

    The suggested classifications of locally recurrent rectal cancer are based on the presence of symptoms and the degree of tumour fixation to the pelvic wall, or, otherwise, account for factor T in the TMN system. Although the results of rectal cancer treatment have improved, which may be attributed to total meso rectal excision and application of perioperative radiotherapy and radiochemotherapy, the ratio of cases of locally recurrent rectal cancer still amount from several to over a dozen percent. Among the available diagnostic methods for detecting locally recurrent rectal cancer after anterior rectal resection, endorectal sonography is of special importance. In the estimation of prognostic factors the lack of vascular invasion in recurrent cancer and the long period between the treatment of primary rectal cancer and the development of recurrence are a sign of good prognosis, while pain prior to recurrence treatment and male sex diminish the chances for cure. Locally recurrent rectal cancer impairs the patient's quality of life in all measurable aspects, but even after complete recovery we observe severe disturbances of sexual activity in most patients, and a number of patients require hygiene pads or suffer from chronic pain. Local recurrence of rectal cancer is more commonly qualified for excision after surgical treatment only, than after preoperative radiotherapy. The probability of total recurrent rectal cancer excision increases when the patient is younger, the primary tumours was less advanced and the first operation was sphincter-sparing surgery. Progress in the surgical treatment of recurrent rectal cancer was brought on by the introduction of the composite musculocutaneous flap to compensate the loss of perineal tissue. The application of intraoperative radiotherapy improves treatment results of recurrent rectal cancer, however at the cost of more frequent, serious postoperative complications and intense pain.

    2010-02-01

    The aim of this retrospective study was to investigate the use of thoracic Computed Tomography (CT) in the Emergency Department of a Dublin Academic Teaching Hospital over a six month period. Data was retrieved using the hospital\\'s computerised information system. There were 202 referrals in total for thoracic CT from the Emergency Department during this time period. The most common indication for thoracic CT referral was for the investigation of pulmonary embolism with 127 (63%) referrals. There were 40 (25%) referrals for suspected malignancy and lung disease, whilst 8 (4%) of the referrals were for investigation of thoracic aortic dissection, 8 (4%) for infection, and 6 (3%) were for investigation of thoracic injury. Only 8 (4%) of all referrals were for investigation of injury as a result of chest trauma.

    We sought to define an accurate measure of thoracic surgical education costs. Program directors from six distinct and differently sized and geographically located thoracic surgical training programs used a common template to provide estimates of resident educational costs. These data were reviewed, clarifying questions or discrepancies when noted and using best estimates when exact data were unavailable. Subsequently, a composite of previously published cost-estimation products was used to capture accurate cost data. Data were then compiled and averaged to provide an accurate picture of all costs associated with thoracic surgical education. Before formal accounting was performed, the estimated average for all programs was approximately $250,000 per year per resident. However, when formal evaluations by the six programs were performed, the annual cost of resident education ranged from $330,000 to $667,000 per year per resident. The average cost of $483,000 per year was almost double the initial estimates. Variability was noted by region and size of program. Faculty teaching costs varied from $208,000 to $346,000 per year. Simulation costs ranged from $0 to $80,000 per year. Resident savings to program ranged from $0 to $135,000 per year and averaged $37,000 per year per resident. Thoracic surgical education costs are considerably higher than initial estimates from program directors and probably represent an unappreciated source of financial burden for cardiothoracic surgical educational programs.

  3. Thoracic fractures and dislocations in motorcyclists

    1987-01-01

    Motorcyclists who are involved in accidents generally suffer severe multiple injuries, some of which are not readily apparent on initial examination. One such subtle injury is fracture, with or without dislocation, in the upper thoracic spine. The severe spinal cord damage produced by the injury is often overshadowed by cerebral or cervical injury. Proper diagnosis is further hampered by the fact that the upper thoracic region is difficult to examine radiographically on plain films, particularly when using portable equipment. Of a group of 14 motorcyclists having 26 fractures and/or dislocations in the thoracic region, 12 had 24 injuries between T3 and T8. These 24 injuries represented 56% of the fractures and/or dislocations encountered in a larger study of trauma to the thoracic vertebral column. All of these were flexion injuries, suffered when the individual was thrown from the motorcycle and struck a large, solid object. In three cases, the diagnosis was delayed as much as 48 h because proper films were not obtained initially. Because of the serious consequences of delayed treatment, we recommended that all motorcyclists who have sustained severe trauma be examined by overpenetrated film of the upper thoracic region.

    1998-01-01

    Purpose: To describe and discuss the thoracic CT features of hypovolemic shock. Material and Methods: From a group of 18 patients with signs of hypovolemia on contrast-enhanced abdominal CT, 11 were selected for our study as having also undergone a complete chest examination. Pulse rate, blood pressure, trauma score value, Glasgow coma scale value, surgical result, and final outcome were retrospectively evaluated. The CT features analyzed were: decreased cardiac volume, reduced caliber of the thoracic aorta, aortic branches and caval venous system, increased enhancement of the aorta, and increased enhancement of the pulmonary collapses/contusions. Results: All 11 subjects presented severe injuries and hemodynamic instability; 7 were stable enough to undergo surgery; only 1 of the 11 survived. Two patients showed none of the features of thoracic hypovolemia. All the other patients presented at least two signs: reduced caliber of the thoracic aorta in 7 cases; decreased volume of the cardiac chambers and increased aortic enhancement in 6; decreased caliber of the aortic vessels in 4; decreased caliber of the caval veins in 3; and increased enhancement of the pulmonary collapses/contusions in 3. Conclusions: In patients with hypovolemia, CT may show several thoracic findings in addition to abdominal ones. Knowledge of these features is important for distinguishing them from traumatic injuries. (orig.)

    The National Quality Forum (NQF) is a multistakeholder, nonprofit, membership-based organization improving health care through preferential use of valid performance measures. NQF-endorsed measures are considered the gold standard for health care measurement in the United States. The Society of Thoracic Surgeons is the steward of the only six NQF-endorsed general thoracic surgery measures. These measures include one structure measure (participation in a national general thoracic surgery database), two process measures (recording of clinical stage and recording performance status before lung and esophageal resections), and three outcome measures (risk-adjusted morbidity and mortality after lung and esophageal resections and risk-adjusted length of stay greater than 14 days after lobectomy).

    The objective of this study was to identify the incidence and patterns of thoracic aortic injuries in a series of blunt traumatic deaths and describe their associated injuries. All autopsies performed by the Los Angeles County Department of Coroner for blunt traumatic deaths in 2005 were retrospectively reviewed. Patients who had a traumatic thoracic aortic (TTA) injury were compared with the victims who did not have this injury for differences in baseline characteristics and patterns of associated injuries. During the study period, 304 (35%) of 881 fatal victims of blunt trauma received by the Los Angeles County Department of Coroner underwent a full autopsy and were included in the analysis. The patients were on average aged 43 years±21 years, 71% were men, and 39% had a positive blood alcohol screen. Motor vehicle collision was the most common mechanism of injury (50%), followed by pedestrian struck by auto (37%). A TTA injury was identified in 102 (34%) of the victims. The most common site of TTA injury was the isthmus and descending thoracic aorta, occurring in 67 fatalities (66% of the patients with TTA injuries). Patients with TTA injuries were significantly more likely to have other associated injuries: cardiac injury (44% vs. 25%, p=0.001), hemothorax (86% vs. 56%, pinjury (74% vs. 49%, pinjury. Patients with a TTA injury were significantly more likely to die at the scene (80% vs. 63%, p=0.002). Thoracic aortic injuries occurred in fully one third of blunt traumatic fatalities, with the majority of deaths occurring at the scene. The risk for associated thoracic and intra-abdominal injuries is significantly increased in patients with thoracic aortic injuries.

    This case study describes the process of examination, re-examination, and intervention for a collegiate runner with mechanical thoracic pain preventing athletic participation and limiting daily function. Unimpaired function fully returned in less than 3 weeks with biweekly sessions to re-establish normal and painfree thoracic mechanics via postural hygiene, exercise, mobilization, and manipulation. The outcome of this case study supports the original hypothesis that the pattern of impairments was in fact responsible for the functional limitations and disability in this athlete. At the time of publication the athlete was without functional limitations and had fully returned to competitive sprinting for the university track team.

    2006-01-01

    Full Text Available Background/Aim. Thoracic drainage is a surgical procedure for introducing a drain into the pleural space to drain its contents. Using this method, the pleura is discharged and set to the physiological state which enables the reexpansion of the lungs. The aim of the study was to prove that the use of modern principles and protocols of thoracic drainage significantly reduces the occurrence of failures and complications, rendering the treatment more efficient. Methods. The study included 967 patients treated by thoracic drainage within the period from January 1, 1989 to June 1, 2000. The studied patients were divided into 2 groups: group A of 463 patients treated in the period from January 1, 1989 to December 31, 1994 in whom 386 pleural drainage (83.36% were performed, and group B of 602 patients treated form January 1, 1995 to June 1, 2000 in whom 581 pleural drainage (96.51% were performed. The patients of the group A were drained using the classical standards of thoracic drainage by the general surgeons. The patients of the group B, however, were drained using the modern standards of thoracic drainage by the thoracic surgeons, and the general surgeons trained for this kind of the surgery. Results. The study showed that better results were achieved in the treatment of the patients from the group B. The total incidence of the failures and complications of thoracic drainage decreased from 36.52% (group A to 12.73% (group B. The mean length of hospitalization of the patients without complications in the group A was 19.5 days versus 10 days in the group B. The mean length of the treatment of the patients with failures and complications of the drainage in the group A was 33.5 days versus 17.5 days in the group B. Conclusion. The shorter length of hospitalization and the lower morbidity of the studied patients were considered to be the result of the correct treatment using modern principles of thoracic drainage, a suitable surgical technique, and a

    Full Text Available PRESENTATION OF CASE Actinomycetes are branching gram-positive anaerobic bacteria belonging to Actinomycetaceae family and are commensals in human oropharynx, gastrointestinal tract and female genitalia. Thoracic or pulmonary actinomycosis is an uncommon bacterial infection. The diagnosis of pulmonary or thoracic actinomycosis is often confounding because of its shared clinical features with malignant lung diseases and chronic suppurative lung diseases. However, chest physicians should be aware of actinomycosis being a differential diagnosis in persistent shadows in lung as early diagnosis leads to good prognosis. 1

    The study includes 1127 injured with thoracic trauma, 23 percent of them with polytrauma. The worse thoracic trauma were these with formed flail chest with pleural and lung complications, accompanied by severe disfunction in circulation and biomechanics of breathing. The application of minimal surgical procedures like pleural punctures and drainage of pleural cavities with aspiration achieved good results. Thoracotomy was performed on clear indications (unstoppable bleeding, large ruptures of lung parenchyma, suppurative lung haematoma, cardiac tamponade, rupture of major airways, rupture of diaphragm, rupture of oesophagus and coagulated haemothorax). The achieved mortality of 5.9 percent is an excellent index suggesting a choice of treatment.

    Our objective was to describe the CT findings of thoracic Wegener's granulomatosis. At presentation, both conventional and thin-section CT scans were available in 30 patients with Wegener's granulomatosis. Serial CT scans (range of intervals: 1-25 months, mean 4.5 months) were available in 20 patients. The initial and follow-up CT scans were analyzed retrospectively by two observers in terms of pattern and extent of parenchymal and airway lesions. Positive CT findings were seen in 29 of 30 (97%) patients at initial presentation. The most common pattern was nodules or masses seen in 27 of 30 (90%) patients. They were multiple in 23 of 27 (85%) patients, bilateral in 18 (67%), subpleural in 24 (89%), and peribronchovascular in 11 (41%) in distribution. Bronchial wall thickening in the segmental or subsegmental bronchi was seen in 22 (73%) patients. Large airways were also abnormal in 9 (30%) patients. Patchy areas of consolidation and ground-glass opacity were seen in 7 (23%) patients, respectively. In 17 of 20 (85%) patients in whom follow-up CT scans were available, the parenchymal or airway lesion showed complete or partial improvement with treatment. The CT findings of Wegener's granulomatosis, although multiple and variable, consist mainly of bilateral subpleural or peribronchovascular nodules or masses and bronchial wall thickening in the segmental or subsegmental bronchi. Parenchymal and airway lesions improve with treatment in most patients. (orig.)

    2013-11-01

    To describe the management of thoracic reconstructions in the presence of primary chest-wall infection (PCWI) or secondary deep chest-wall infection (SCWI), focussing on local tolerance of a titanium rib osteosynthesis system. PCWI included infected chest wall tumours (CWT), infected T3 non-small-cell lung carcinoma (NSCLC) and open flail chest. SCWI was defined by deep infection of previous thoracic-wall reconstructions. Infection was identified by preoperative bacterial analysis of the tumour or surgical site. In PCWI, a one-step procedure combined extensive resection of infected tissues and rigid reconstruction of the defect; skeletal rigidity was achieved using titanium implants. In SCWI, we removed all synthetic material except titanium implants. In both groups, the surgical field was thoroughly cleaned and implants were wrapped or covered by flaps. From January 2005 to December 2011, 11 patients (54 ± 10.2 years) with either PCWI (3 CWT, 3 T3 NSCLC, 1 open flail chest) or SCWI (3 CWT, 1 funnel chest) were treated. Infection was polymicrobial in all but 1 case. Bacteria observed in PCWI patients were multidrug resistant. In PCWI, we resected 4.2 ± 0.6 ribs en bloc with the lung (n = 5), the skin and the pectoralis major and then used mesh and 2.1 ± 1.2 titanium implants for reconstruction (n = 6). The mean defect was 1154.4 ± 318 cm(3). Surgical SCWI management removed polytetrafluoroethylene-mesh and preserved the titanium implants. A Vicryl mesh (n = 3) and greater omentum flap (n = 3) were added. One of the 2 postoperative deaths in the PCWI group was related to infection recurrence. No other patient had infection at the 6-month follow-up with leucocyte-labelled scintigraphy. Titanium rib osteosynthesis is reliable in two complex and life-threatening situations: PCWIs and SCWIs. In combination with a flap, this allows rapid, reliable, rigid reconstruction of infected full-thickness chest-wall defects in a single-step procedure.

    2014-09-01

    The aim of this study was to update our previous experience and describe long-term results after resection of non-small-cell lung cancer (NSCLC) invading the thoracic inlet. Patients from a single center undergoing resection of NSCLC invading the thoracic inlet were reviewed with data retrieved retrospectively from their charts. Sixty-five consecutive patients with a median age of 61 (32-76) years underwent resection of NSCLC invading the thoracic inlet from 1991 to 2011. Tumor location was divided into 5 anatomic zones from anterior to posterior. Fifty-two (80%) patients had induction therapy, mostly with 2 cycles of cisplatin-etoposide and 45 Gy of concurrent irradiation. All patients underwent at least first rib resection. Lobectomy was performed in 60 patients (92%). Twenty-four patients (37%) had vertebral resection. Arterial resections were performed in 7 patients (11%). Postoperative morbidity and mortality were 46% and 6%, respectively. Pathologic response to induction was complete (pCR) (n = 19) or nearly complete (pNR) (n = 12) in 31 patients (48%). Adjuvant treatment was administered in 14 (25%) patients. After a median follow-up of 20 (0-193) months, 34 patients are alive without recurrence. The overall 5-year survival reached 69%. Univariate analysis identified site of tumor within the thoracic inlet (p = 0.050), response to induction (p = 0.004), and presence of adjuvant treatment (p = 0.028) as survival predictors. Survival after resection of NSCLC invading the thoracic inlet in highly selected patients reached 69% at 5 years. Tumor location within the thoracic inlet, pathologic response to induction therapy, and adjuvant treatments were significant survival predictors. Copyright © 2014 The Society of Thoracic Surgeons.

    Full Text Available A full term boy was admitted with respiratory distress in the fourth week of his life due to spontaneous chylothorax in his right hemithorax. Spontaneous chylothorax occurred previously in a first cousin of the neonate establishing that way the final diagnosis of familial idiopathic congenital pneumothorax. Failure of the conservative treatment consisting of chest tube drainage, discontinuation of oral diet and administration of total parenteral nutrition in combination with octreotide for one month was followed by the successful ligation of the thoracic duct through a right thoracotomy. The boy still remains free of symptoms and without recurrence of the chylothorax two years later.

    In summary a fascinating case is presented in a 54-year-old man who developed a chordoma of the fourth lumbar vertebra which was treated by radiotherapy, with good results. The man remained asymptomatic relatively for several years and then presented with recurrence of back pain and neurological deficits. Plain films, CT and myelography showed considerable destruction of the body of L4 with a sclerotic pattern suggesting the effects of previous radiotherapy. A large paraspinal tissue mass extending into the spinal canal was present. Most interestingly the patient developed metastatic disease in the thoracic spine and ribs but no metastases other than in the skeleton. (orig./SHA)

    Cervical thoracic duct cysts are a rare anomaly. To report a case of cervical thoracic duct cyst, and perform a literature review. A 78-year-old female, with a one-year history of a left-sided asymptomatic supraclavicular cystic mass. Computerized tomography revealed a cystic mass 42mm in diameter. We performed a fine needle aspiration puncture, obtaining a thick, milky, whitish liquid. The patient underwent surgery; finding a left-sided supraclavicular cystic mass, with some lymph vessels heading towards the jugulo subclavian venous junction. We performed a ligation of these lymph vessels and resection of the mass. The histopathologic study confirmed the diagnosis of thoracic duct cyst. Diagnosis of cervical thoracic duct cyst should be suspected with a cystic lesion in the left supraclavicular region, which when perforated exudes a very distinctive thick milky, whitish liquid with a high content of lymphocytes and triglycerides. Treatment should be complete removal with ligation of the lymphatic afferent vessels. Copyright © 2016 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A. All rights reserved.

    To determine the presentation and management outcome of thoracic trauma in a tertiary care setting. A total of 143 patients, who presented with chest trauma, were included in the study. All the patients were assessed by the history, physical examination and ancillary investigations. Appropriate managements were instituted as required. Data was described in percentages. out of 143 patients, 119 (83)% were males and 24 (17)% were females. Most of the patients belonged to the age group of 21-50 years. Ninety seven (66)% patients were admitted for indoor management. Blunt injury was found in 125 (87.4%) patients, while penetrating injuries in only 18 (12.6%) patients. Road Traffic Accidents (RTAs) were the commonest cause of trauma (n=103, 72%). Rib fracture was the commonest chest injury (74% patients). Head injury was the most frequently associated injury (18% of the patients). Tube thoracostomy was the commonest intervention undertaken in 65 (45%) patients. Seventeen (11.88%) patients were managed with mechanical ventilation. there were 17 deaths with a mortality rate of 11.88%. Thoracic trauma is an important cause of hospitalization, morbidity and mortality in the younger population. RTAs constitute the leading cause of thoracic trauma in our setup. Tube thoracostomy is the most frequent and at times the only invasive procedure required as a definitive measure in thoracic trauma patients. A policy of selective hospitalization helps to avoid unnecessary hospital admissions. (author)

    A retrospective analysis of a consecutive series of patients treated with krypton red laser (KRL) photocoagulation for subretinal neovascularization (SRN) secondary to drusen-related macular degeneration (DMD) was carried out to investigate the frequency and nature of recurrent neovascularization (recurrence). A classification of various types of recurrences based on the clinical and fluorescein angiographic features and the onset of their appearance in the postoperative course was used in this study. Patient, fundus, and membrane variables were examined in search of relevant high risk factors predisposing to recurrences. The membrane's proximity to the fovea and its relative lack of pigmentation were individual factors which were associated with a high risk of recurrence (P less than 0.05 for distance and P = 0.005 for color). Multivariate analysis also indicated that a greater distance from the fovea (P less than 0.05) and a darker color (P = 0.002) were favorable features to the primary membrane, reducing the probability of a recurrence. Overall, 39% of the patients experienced recurrences (23% of the patients had treatable recurrences and 16% had non-treatable recurrences extending under the center of the fovea). The membranes recurred predominantly at the margin of the photocoagulation burn. The recurrences were also noted relatively early in the postoperative course, 65% within two months after photocoagulation of the primary membrane. The fluorescein angiographic and clinical nature of these membranes and the visual effect of retreatment are also discussed in the paper.

    Computational fluid dynamics tools have been used to investigate blood flow through the human thoracic aortic models with aneurysm before and after virtual stent graft operation. The impact of blood rheology and aortic geometry on the wall shear stress (WSS), luminal surface low-density lipoproteins (LDL) concentration, and oxygen flux along the arterial wall is investigated. The stent graft at the aneurysm has significant effects on WSS and mass transport in blood flow. Due to the low flow rate, Newtonian blood assumption generally under-estimates the WSS. The non-Newtonian blood rheology play an important role in the LDL transport as well as oxygen transport. It is found that WSS alone is insufficient to correctly predict the location with high risk of atherogenesis. The results suggest that WSS, luminal surface LDL concentration, and the oxygen flux on the wall have to be considered together to evaluate the performance of virtual operation.

    Spinal teratomas are extremely rare; they constitute meningitis. A 7-year-old boy presented with paroxysmal abdominal pain and a history of recurrent aseptic meningitis. Kernig and Brudzinski signs were present. Lumber puncture revealed pleocytosis with no evidence of bacteria growth. Imaging of the spine revealed a cystic lesion in spinal cord at thoracic level 9-11. Endoscopic excision of the cyst was successfully performed. Surgical and histopathological findings confirmed extramedullary matured teratoma. As the symptomatic attacks of spontaneous rupture of spinal teratoma resemble presentations of Mollaret meningitis, spinal teratoma should be considered in the differential diagnosis of Mollaret meningitis. We describe a rare example of spinal teratoma causing recurrent meningitis. Spine imaging should be considered in individuals with recurrent aseptic meningitis as this promotes earlier diagnosis, more appropriate treatment, and improved neurological outcome.

    To evaluate the aortic wall atherosclerosis, X-ray CT and ECG gated radionuclide angiography were performed in 25 subjects. They were classified into 17 normotensive group (N) and 8 hypertensive group (HT). The time-activity curve was generated using radionuclide angiography in the portion of the thoracic aorta. The aortic wall distensibility was expressed as 100ΔV/V 0 / PP, where ΔV was difference between maximum and minimum (V 0 ) counts of the aorta, and PP was pulse pressure. The degree of the aortic wall atherosclerosis was evaluated by X-ray CT. The aortic wall CT-score was calculated from the CT-scores measured whithin the region of interest of the other margin of the aorta and of the background by X-ray CT. There was a significant correlation between aortic wall CT-score and systolic blood pressure (r=0.59, p<0.01) or aortic wall distensibility (r=-0.74, p<0.01)), but no correlation existed between aortic wall CT-score and diastolic blood pressure (r=0.11, p:NS). The aortic wall distensibility was higher and the aortic wall CT-score was lower in N-group than in HT-group, whereas there was no difference of the radius of the aorta between both groups. These results suggest that the aortic wall atherosclerosis advanced progressively in hypertensive patients and systolic blood pressure was a good predictor of the degree of the aortic atherosclerosis.

    Osteoblastomas are bone forming lesions arising mainly from posterior elements of the vertebra. They are commonly encountered in the cervical and lumbar regions. We present a case of a thoracic osteoblastoma which is extra osseous and is not communicating with any part of the vertebra present intraforaminally. This is a rare presentation of an osteoblastoma. Imaging studies do not accurately diagnose the osteiod lesion. The size of the lesion and cortical erosion seen on the computed tomography scan help in differentiating the osteoid osteoma and osteoblastoma, but they are less sensitive and specific. Thus a histopathology is the investigation of choice to diagnose the osteoblastoma. Early and adequate removal of mass prevents malignant transformation, metastasis, and recurrence. In our case we excised the pars interarticularis unilaterally, removed the osteoid mass intact, and performed unilateral instrumented fusion. There was no recurrence and solid fusion was seen at 3 years follow up. PMID:25346825

    Loss of thoracic kyphosis has been associated with thoracic idiopathic scoliosis. Modern 3-dimensional (3D) imaging systems allow more accurate characterization of the scoliotic deformity than traditional radiographs. In this study, we utilized 3D calculations to characterize the association between increasing scoliosis severity and changes in the sagittal and axial planes. Patients evaluated in a scoliosis clinic and determined to have either a normal spine or idiopathic scoliosis were included in the analysis. All underwent upright, biplanar radiography with 3D reconstructions. Two-dimensional (2D) measurements of the magnitude of the thoracic major curve and the thoracic kyphosis were recorded. Image processing and MATLAB analysis were utilized to produce a 3D calculation of thoracic kyphosis and apical vertebral axial rotation. Regression analysis was performed to determine the correlation of 2D kyphosis, 3D kyphosis, and apical axial rotation with the magnitude of the thoracic major curve. The 442 patients for whom 2D and 3D data were collected had a main thoracic curve magnitude ranging from 1° to 118°. Linear regression analysis of the 2D and 3D T5-T12 kyphosis versus main thoracic curve magnitude yielded significant models (p scoliosis magnitude increased, at a rate of more than half the increase in the main thoracic curve magnitude. Analysis confirmed a surprisingly strong correlation between scoliosis severity and loss of 3D kyphosis that was absent in the 2D analysis. A similarly strong correlation between curve magnitude and apical axial rotation was evident. These findings lend further credence to the concept that scoliosis progresses in the coronal, sagittal, and axial planes simultaneously. The findings of this study suggest that 3D assessment is critical for adequate characterization of the multiplanar deformity of idiopathic scoliosis and deformity in the sagittal plane is linked to deformity in the coronal plane. Increasing severity of coronal

    Malignant primary tumours occurring in the thorax encompass a large group of tumours which may arise from the lung, mediastinal structures, the pleura or the chest wall. We report the case of a 37 year old patient, who presented with left sided chest pain. On clinical examination a right sided chest wall mass was identified. Chest X Ray showed a left sided upper mediastinal opacity, associated with a left sided pleural opacity. Thoracic CT scan revealed a large mass arising from the chest wall and infiltrating the mediastinum associated with a second chest wall mass at the level of the 8(th) and 9(th) right ribs. The biopsy of the chest wall mass revealed it to be a parietal synovialosarcoma. The patient responded to chemotherapy based on ifosfamid and doxorubicin as well as mediastino-pulmonary radiotherapy. There was an improvement in the patient's clinical and radiological state but the patient died by pulmonary embolism after the 3(rd) cause of treatment. Chest wall synovialosarcoma has a poor prognosis, however, its chemosensitivity means that treatment may initially be effective. Copyright © 2011 SPLF. Published by Elsevier Masson SAS.

  7. Dry needling for the management of thoracic spine pain

    2015-01-01

    Thoracic spine pain is as disabling as neck and low back pain without receiving the same level of attention in the scientific literature. Among the different structures that can refer pain to the thoracic spine, muscles often play a relevant role. Trigger points (TrPs) from neck, shoulder and spinal muscles can induce pain in the region of the thoracic spine. There is a lack of evidence reporting the presence of TrPs in the region of the thoracic spine, but clinical evidence suggests that TrPs can be a potential source of thoracic spine pain. The current paper discusses the role of TrPs in the thoracic spine and dry needling (DN) for the management of TrPs in the thoracic multifidi and longissimus thoracis. This paper also includes a brief discussion of the application of DN in other tissues such as tendons, ligaments and scars. PMID:26309385

    Radical resection of thymoma is the most important predictor of survival; despite a complete resection, 10-30% of patients develop a recurrence. The surgical treatment of thymic relapses is an accepted therapeutic approach; however, no clear data are available yet regarding the indication for surgery and the long-term prognosis of this subset of patients. The aim of our work was to review the data of a group of recurrent thymomas treated by surgery, comparing it with non-surgical therapy, and analysing the outcome and the prognostic factors. Between 1980 and 2010, 880 patients with thymoma underwent complete macroscopical resection and were followed up for recurrence. Masaoka stage IVa and type C thymic tumours were excluded from the study. A total of 82 (9.3%) patients developed a recurrence, and 52 (63.4%) were reoperated. The other 21 patients, originally operated outside, underwent surgical resection of recurrence. Finally, 73 patients were operated on for recurrent thymoma and 30 received medical treatment. This entire cohort represents the subject of the study. There were 57 (55.3%) males and 46 (44.7%) females. The median time to relapse was 50 months. Sixty-three (61.2%) recurrences were regional, 17 (16.5%) local, 14 (13.6%) distant, 6 (5.8%) regional and distant, and 3 (2.9%) local, regional and distant. No operative mortality was observed. In 50 (68.5%) patients, a macroscopic complete resection was accomplished. The 5- and 10-year overall survival rates from recurrence were 63 and 37%, respectively. Complete surgical resection was associated with a significant better survival when compared with incomplete surgical resection and non-surgical treatment (P thymoma is effective and safe, achieving a prolonged survival. Complete macroscopic resection and single recurrence are associated with better prognosis. © The Author 2015.

  9. Domain wall diffusion and domain wall softening

    International Nuclear Information System (INIS)

    Lee, W T; Salje, E K H; Bismayer, U

    2003-01-01

    A number of experimental and computational studies of materials have shown that transport rates in domain walls may significantly differ from those in the bulk. One possible explanation for enhanced transport in a domain wall is that the domain wall is elastically soft with respect to the bulk. We investigate the softening of a ferroelastic domain wall in a simple, generic model. We calculate saddle point energies of solute atoms in the bulk and domain wall, using a geometry such that variation in the saddle point energy cannot be attributed to the structural differences of the bulk and the wall, but must instead be attributed to softening of the wall. Our results show a reduction of the saddle point energy in the wall, thus indicating that, in this model at least, domain walls are elastically soft compared with the bulk. A simple analysis based on an Einstein model allows us to explain the observed softening of the wall

    The purpose of this study was to identify the effects of a corrective exercise for thoracic hyperkyphosis on posture, balance, and well-being in Korean community-dwelling older women. Fifty women 65 years of age and older, recruited from 2 senior centers, participated in this study. Participants were assigned to either the experimental group (EG) or the control group (CG) on the basis of convenience of location, and 22 in each were analyzed. Participants in the EG underwent a thoracic corrective exercise program 1 hour each session, twice per week for 8 weeks (a total of 16 sessions), which consisted of specific exercises to enhance breathing, thoracic mobility and stability, and awareness of thoracic alignment. The CG received education on the same thoracic corrective exercise program and a booklet of the exercises. Outcome measures included the extent of postural abnormality (angle of thoracic kyphosis, kyphosis index calculated both in relaxed- and best posture using flexicurve, the ratio of the kyphosis index calculated best posture/relaxed posture, craniovertebral angle, and tragus-to-wall distance), balance (Short Physical Performance Battery and limit of stability), and well-being (Geriatric Depression Scale Short Form and the 36-Item Short Form Health Survey [SF-36]). All data were collected by 6 blinded assessors at baseline, at 8 weeks after the completion of intervention, and at 16 weeks for follow-up. For participants of the EG, means of all parameters showed significant improvements over time (P posture, balance, and well-being in older women with thoracic hyperkyphosis. We recommend the use of the therapeutic strategies utilized in this study to enhance thoracic posture, balance, and well-being of older women with thoracic hyperkyphosis. Future research is needed to apply this exercise protocol on a larger and more diverse population.

    A best evidence topic in cardiovascular surgery was written according to a structured protocol. The question addressed was whether the thoracic aorta is a safe site for the proximal anastomosis when bypassing the mesenteric arteries in patients with chronic mesenteric ischaemia. Five articles reported the use of the thoracic aorta as the site of proximal anastomosis in 35 patients with chronic mesenteric ischaemia. All of these studies were retrospective case reports or case series. The ascending aorta was the site for the proximal anastomosis in 7 patients with the descending thoracic aorta being used in the other 28 patients. The ascending aorta was used when there was disease of the descending thoracic aorta. Out of the 35 patients there was only 1 perioperative death (3%). Rates of graft patency and freedom from recurrent symptoms were excellent. The published literature supports the use of the thoracic aorta as an option for the site of the proximal anastomosis when bypass from elsewhere is not possible. © The Author 2017.

    Full Text Available Minimal invasive surgery has become the standard of care for operations involving the thoracic and abdominal cavities for all ages. Laparoscopic complications can occur as well as more invasive surgical procedures and we can classify them into non-specific and specific. Our goal is to analyze the most influential available scientific literature and to expose important and recognized advices in order to reduce these complications. We examined the mechanism, risk factors, treatment and tried to outline how to prevent two major abdominal wall complications related to laparoscopy: bleeding and port site herniation .

    A total body plethysmograph is descirbed which was used to study thoracic gas volume (TGV) in infants and young children from birth to 2 1/2 years, and was suitable for use even in very sick babies. Normal TGV values were obtained in 42 studies of 35 healthy infants and young children, and 16 children with abnormal lung volume are described. TGV correlated well with length, weight, chest circumference, and age in the healthy infants. A low TGV was found in children with respiratory difficulties after cardiac and thoracic surgery, in respiratory distress syndrome of the newborn, and in association with pulmonary infection and chest cage abnormalities. Abnormally high TGV was most frequently seen in infants with small airways disease. PMID:1008592

    The cardiac structures are well seen on nongated thoracic computed tomography studies in the investigation and follow-up of cardiopulmonary disease. A wide variety of findings can be incidentally picked up on careful evaluation of the pericardium, cardiac chambers, valves, and great vessels. Some of these findings may represent benign variants, whereas others may have more profound clinical importance. Furthermore, the expansion of interventional and surgical practice has led to the development and placement of new cardiac stents, implantable pacemaker devices, and prosthetic valves with which the practicing radiologist should be familiar. We present a collection of common incidental cardiac findings that can be readily identified on thoracic computed tomography studies and briefly discuss their clinical relevance.

    In a first part, the different techniques of digital thoracic radiography are described. Since computed radiography with phosphore plates are the most commercialized it is more emphasized. But the other detectors are also described, as the drum coated with selenium and the direct digital radiography with selenium detectors. The other detectors are also studied in particular indirect flat panels detectors and the system with four high resolution CCD cameras. In a second step the most important image processing are discussed: the gradation curves, the unsharp mask processing, the system MUSICA, the dynamic range compression or reduction, the soustraction with dual energy. In the last part the advantages and the drawbacks of computed thoracic radiography are emphasized. The most important are the almost constant good quality of the pictures and the possibilities of image processing.

    BACKGROUND: Road deaths fell initially after the introduction of the penalty points but despite this, the rate of spinal injuries remained unchanged. AIMS: We report a patient with a dramatic spinal injury, though without neurological deficit. We discuss the classification, management and economic impact of these injuries. METHODS: We describe the management of a patient with a comminuted thoracic spinal fracture without neurological injury. We conducted a literature review with regard to the availability of literature of the management of these injuries. RESULTS: This 17-year-old female was managed surgically and had a good functional outcome. There is no clear consensus in the published literature on the management of these injuries. CONCLUSIONS: Comminuted thoracic spinal factures are potentially devastating. Such a patient presents challenges in determining the appropriate treatment.

    Despite remarkable progress in imaging modalities and surgical management, persistence or recurrence of primary hyperparathyroidism (PHPT) still occurs in 2.5-5% of cases of PHPT. The aim of this review is to expose the management of persistent and recurrent hyperparathyroidism. A literature search was performed on MEDLINE using the search terms "recurrent" or "persistent" and "hyperparathyroidism" within the past 10 years. We also searched the reference lists of articles identified by this search strategy and selected those we judged relevant. Before considering reoperation, the surgeon must confirm the diagnosis of PHPT. Then, the patient must be evaluated with new imaging modalities. A single adenoma is found in 68% of cases, multiglandular disease in 28%, and parathyroid carcinoma in 3%. Others causes (<1%) include parathyromatosis and graft recurrence. The surgeon must balance the benefits against the risks of a reoperation (permanent hypocalcemia and recurrent laryngeal nerve palsy). If surgery is necessary, a focused approach can be considered in cases of significant imaging foci, but in the case of multiglandular disease, a bilateral neck exploration could be necessary. Patients with multiple endocrine neoplasia syndromes are at high risk of recurrence and should be managed regarding their hereditary pathology. The cure rate of persistent-PHPT or recurrent-PHPT in expert centers is estimated from 93 to 97%. After confirming the diagnosis of PHPT, patients with persistent-PHPT and recurrent-PHPT should be managed in an expert center with all dedicated competencies.

  20. One-stage sequential bilateral thoracic expansion for asphyxiating thoracic dystrophy (Jeune syndrome).

    Jeune syndrome (asphyxiating thoracic dystrophy) is a rare disorder characterized by skeletal dysplasia, reduced diameter of the thoracic cage and extrathoracic organ involvement. Fatal, early respiratory insufficiency may occur. Two-stage lateral thoracic expansion has been reported, addressing each side sequentially over 3-12 months. While staged repair theoretically provides less invasive surgery in a small child with respiratory distress, we utilized a single stage, bilateral procedure aiming to rapidly maximize lung development. Combined bilateral surgery also offered the chance of rapid recovery, and reduced hospital stay. We present our early experience of this modification of existing surgical treatment for an extremely rare condition, thought to be generally fatal in early childhood. Nine children (6 males, 3 females; median age 30 months [3.5-75]) underwent thoracic expansion for Jeune syndrome in our centre. All patients required preoperative respiratory support (5 with tracheostomy, 8 requiring positive pressure ventilation regularly within each day/night cycle). Two children underwent sequential unilateral (2-month interval between stages) and 7 children bilateral thoracic expansion by means of staggered osteotomies of third to eighth ribs and plate fixation of fourth to fifth rib and sixth to seventh rib, leaving the remaining ribs floating. There was no operative mortality. There were 2 deaths within 3 months of surgery, due to pulmonary hypertension (1 following two-stage and 1 following single-stage thoracic expansion). At the median follow-up of 11 months (1-15), 3 children have been discharged home from their referring unit and 2 have significantly reduced respiratory support. One child remains on non-invasive ventilation and another is still ventilated with a high oxygen requirement. Jeune syndrome is a difficult condition to manage, but bilateral thoracic expansion offers an effective reduction in ventilator requirements in these children

    To explore the utility of lung magnetic resonance imaging (MRI) in children with thoracic tuberculosis (TB). This prospective study of forty children (age range of 5 to 15 y) with thoracic TB was approved by the institutional ethics committee. Chest radiograph, lung MRI and computed tomography (CT) scan were performed in all children. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) of MRI were calculated and kappa test of agreement was used to determine the strength of agreement between the MRI and CT findings. MRI performed equivalent to CT scan in detection of mediastinal and hilar lymphadenopathy, pleural effusion and lung cavitation (considered typical for TB) with sensitivity and specificity of 100%. MRI also yielded a sensitivity of 88.2% and specificity of 95.7% for nodules, with sensitivity of 100% and specificity of 92.9% for consolidation. Kappa agreement between CT and MRI in detection of each finding was almost perfect (k: 0.8-1). Although CT scan is still superior to MRI in detection of smaller nodules, MRI demonstrates a very high degree of correlation and agreement with CT scan for detecting lung and mediastinal pathology related to TB, in children with thoracic TB and can be particularly useful in select population and follow-up of these children to avoid repeated radiation exposures.

    Introduction Recurrent laryngeal nerve injury caused by cardiovascular disease is a rare condition, and often it is the only prominent sign of an imminent break of an aortic artery aneurysm. Objective To report left laryngeal paralysis caused by a great aortic arch aneurysm and to highlight the importance of an otorhinolaryngologic evaluation along with a thoracic radiologic study. Resumed Report A 42-year-old man complained of thickness of his voice and dysphagia for 3 months, but no thoracic pain or other relevant complaints. Video laryngoscopy revealed immobility of his left vocal fold in the paramedian position. Imaging was obtained for investigation, including magnetic resonance imaging of his thorax, which showed a fusiform aneurysm in the aortic arch, leading to recurrent compression of the left laryngeal nerve. The patient was successfully treated with endovascular repair of the aneurysm. At 2-month follow-up, there was still no recovery of the laryngeal mobility. Conclusion An aortic artery aneurysm can suddenly break, requiring emergency heart surgery, and the results can be fatal in many cases. We suggest routine exam of the vocal folds in all patients with a heart condition, and we review the literature and suggest the use of imaging to reduce the number of emergency procedures.

    The essential points of video-assisted thoracic surgery (VATS) for acute thoracic empyema are the decortication of thickened pleura, resection of necrotic tissues and fibrin blocks, and drainage. Pulsed lavage irrigation, which is commonly used in orthopedic surgery as a method of sufficiently performing the technique, was used under a thoracoscope to study the efficacy of the treatment for acute thoracic empyema. The subjects comprised 31 patients who had undergone VATS for acute thoracic empyema. There were 26 men and 5 women with an average age of 60.5 years. For the surgical technique, the thickened pus-producing pleura were decorticated under a thoracoscope. The pulsed lavage irrigation system was used after the intrathoracic space had become a single cavity. Using the tip for an intraspinal space, lavage and suctioning were repeated with 5-10 l of a pressurized warm saline solution. Fibrin blocks and necrotic tissues were easily removed by spray washing with pressurized fluid. The operating time was 150.8 min; the amount of bleeding, including suctioned pleural effusion, was 478.5 g; and the postoperative duration of drainage was 10.7 days. During the postoperative course, the addition of open window thoracotomy due to the relapse of empyema due to methicillin-resistant Staphylococcus aureus was observed in only one patient (3.2%). All of the other patients improved despite their concomitant diseases. The use of pulsed lavage irrigation under a thoracoscope for acute thoracic empyema provides simple, efficient débridement or drainage.

    Thoracic disc herniation is a relatively rare yet challenging-to-diagnose condition. Currently there is no universally accepted optimal surgical treatment for symptomatic thoracic disc herniation. Previously reported surgical approaches are often associated with high complication rates. Here we describe our minimally invasive technique of removing thoracic disc herniation, and report the primary results of a series of cases. Between January 2009 and March 2012, 13 patients with symptomatic thoracic disc herniation were treated with endoscopic thoracic foraminotomy and discectomy under local anesthesia. A bone shaver was used to undercut the facet and rib head for foraminotomy. Discectomy was achieved by using grasper, radiofrequency, and the Holmium-YAG laser. We analyzed the clinical outcomes of the patients using the visual analogue scale (VAS), MacNab classification, and Oswestry disability index (ODI). At the final follow up (mean: 17 months; range: 6–41 months), patient self-reported satisfactory rate was 76.9%. The mean VAS for mid back pain was improved from 9.1 to 4.2, and the mean ODI was improved from 61.0 to 43.8. One complication of postoperative spinal headache occurred during the surgery and the patient was successfully treated with epidural blood patch. No other complications were observed or reported during and after the surgery. PMID:24455232

    Chylopericardium rarely occurs in pediatric patients, but when it does it is most often a result of lymphatic injury during cardiothoracic surgery. Primary idiopathic chylopericardium is especially rare, with few cases in the pediatric literature. We report a 10-year-old boy who presented with primary idiopathic chylopericardium after unsuccessful initial treatment with surgical lymphatic ligation and creation of a pericardial window. Following readmission to the hospital for a right-side chylothorax resulting from the effluent from the pericardial window, he had successful treatment by interventional radiology with percutaneous thoracic duct embolization. This case illustrates the utility of thoracic duct embolization as a less-invasive alternative to surgical thoracic duct ligation, or as a salvage procedure when surgical ligation fails. (orig.)

  9. Falling walls

    CERN Multimedia

    It was 20 years ago this week that the Berlin wall was opened for the first time since its construction began in 1961. Although the signs of a thaw had been in the air for some time, few predicted the speed of the change that would ensue. As members of the scientific community, we can take a moment to reflect on the role our field played in bringing East and West together. CERN’s collaboration with the East, primarily through links with the Joint Institute for Nuclear Research, JINR, in Dubna, Russia, is well documented. Less well known, however, is the role CERN played in bringing the scientists of East and West Germany together. As the Iron curtain was going up, particle physicists on both sides were already creating the conditions that would allow it to be torn down. Cold war historian Thomas Stange tells the story in his 2002 CERN Courier article. It was my privilege to be in Berlin on Monday, the anniversary of the wall’s opening, to take part in a conference entitled &lsquo...

    Graphite and C/C composite are used recently for the first wall of a thermonuclear device since materials with small atom number have great impurity allowable capacity for plasmas. Among them, those materials having high thermal conduction are generally anisotropic and have an upper limit for the thickness upon production. Then, anisotropic materials are used for a heat receiving plate, such that the surfaces of the heat receiving plate on the side of lower heat conductivity are brought into contact with each other, and the side of higher thermal conductivity is arranged in parallel with small radius direction and the toroidal direction of the thermonuclear device. As a result, the incident heat on an edge portion can be transferred rapidly to the heat receiving plate, which can suppress the temperature elevation at the surface to thereby reduce the amount of abrasion. Since the heat expansion coefficient of the anisotropic materials is great in the direction of the lower heat conductivity and small in the direction of the higher heat conductivity, the gradient of a thermal load distribution in the direction of the higher heat expansion coefficient is small, and occurrence of thermal stresses due to temperature difference is reduced, to improve the reliability.

    The aim of this study was to clearly delineate the anatomical variations of the communicating rami in the upper thoracic sympathetic nervous system and to help develop better surgical method for essential palmar hyperhidrosis. Anatomical dissections of the upper thoracic sympathetic chains with sympathetic ganglia and communicating rami have been carried out in 42 adult Korean cadavers (male 26, female 16). The rami communicantes were classified into three types (Normal: transverse or oblique rami connected to the intercostal nerve of the same level; AR: ascending rami connected to the higher level; DR: descending rami to the lower level) based on the anatomical relationship of the thoracic sympathetic ganglia to the intercostal nerves. Both sides of the upper thoracic sympathetic nervous system were compared in the same individual. The number of the communicating rami was recorded in 32 cadavers (64 sides). The distance from the rami communicantes to the sympathetic trunk was measured in 26 cadavers (52 sides). The incidence of AR (ascending rami) and DR (descending rami) arising from the second sympathetic ganglion was 53.6% (45/84), 46.4% (39/84). From the third thoracic sympathetic ganglion, the incidence of AR was 5.9% (5/84) and that of DR was 26.2% (22/84). And in the fourth thoracic sympathetic ganglion, the incidence of AR was 4.8% (4/84) and DR was 8.3% (7/84), respectively. When we compared anatomical structures of both sides among the 42 cadavers dissected, only 14.3% (6/42) had similar anatomy of the rami communicantes bilaterally. Among 32 cadavers (64 sides), the mean number of rami communicantes at the second thoracic sympathetic ganglion was 2.1/2.5 in the left and the right side. At the third and the fourth thoracic sympathetic ganglion, the mean number was 1.9/1.6 and 1.7/1.7 in each side. The mean distance from the thoracic sympathetic chain to the most distal communicating rami of the left and right side at the second intercostal nerve was 7

    Herniated thoracic intervertebral disc is a rare cause of spinal cord compression. Its frequency varies from 0.15% to 1.7% of all disc herniations, and produces symptoms in 0.5% to 0.8%. Case 1. A 50-year-old woman, with pain and burning sensation in left hemithorax of four months of onset. It was treated as a herpetic syndrome, with no improvement. She was seen after thirteen days of exacerbation of clinical symptoms. The physical examination showed asymmetric paraparesis, lower left pelvic limb 1/5, and right pelvic limb 3/5¸ sensory level T8, with left Babinski positive. A thoracic disc herniation in space T8-T9 was diagnosed. A 55-year-old patient with a history of presenting pain in lumbar area of 5 years onset. She also had radicular pain that radiated to the right pelvic limb, with intensity 10/10 on a Visual Analogue Scale. Her physical examination showed muscle strength 5/5, with normal sensitivity in all dermatomes and tendon reflexes, and a positive right Babinski. Thoracic disc herniation T7-T8 level was diagnosed. Due to anatomical conditions that define this type of hernia, the extracavitary posterolateral approach should be the recommended surgical procedure when the simultaneously performed anterior decompression and fixation with posterior instrumentation are the treatments proposed. Despite the different anatomical structures of this special area, it was possible to obtain satisfactory results for both clinical cases. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    Homer's Iliad is considered to be a prominent and representative work of the tradition of the ancient Greek epic poetry. In this poem Homer presents the battles which took place during the last year of the 10-year lasting Trojan War between Achaeans and Trojans. We wanted to examine the chest wounds, especially those which are described in detail, according to their localization, severity and mortality. Finally, there are reported 54 consecutive thoracic injuries in the Iliad. The mostly used weapons were the spear (63%), the stones (7.4%), the arrow (5.5%) and the sword (5.5%). We divided the injuries according to their severity in mild (those which did not cause serious injury to the victim), medium (those which cause the victim to abandon the battlefield), and severe (those which cause death of the victim). According to this classification, the reported injuries were mild in 11.11%, medium in 18.52%, and severe in the last 70.37% of the reported cases. In other words, 89% of the injuries belong to the medium or severe category of thoracic injury. As far as the mortality of the injuries is concerned, 38 out of 54 thoracic injuries include death, which makes the mortality percentage reach 70.37%. Concerning the "allocation of the roles", the Achaean were in 68% perpetrators and the Trojans in only 32%. In terms of gravity, out of 38 mortal injuries 30 involve a Trojan (78.95%) and the remaining 8 an Achaean (21.05%). The excellent and detailed description of the injuries by Homer, as well as of the symptoms, may reveal a man with knowledge of anatomy and medicine who cared for the injured warriors in the battlefield.

  17. The thoracic outlet syndromes: Part 1. Overview of the thoracic outlet syndromes and review of true neurogenic thoracic outlet syndrome.

    The thoracic outlet syndromes (TOSs) are a group of etiologically and clinically distinct disorders with 1 feature in common: compression of 1 or more neurovascular elements as they traverse the thoracic outlet. The medical literature reflects 5 TOSs: arterial; venous; traumatic neurovascular; true neurogenic; and disputed. Of these, the first 4 demonstrate all of the features expected of a syndrome, whereas disputed TOS does not, causing many experts to doubt its existence altogether. Thus, some categorize disputed TOS as a cervicoscapular pain syndrome rather than as a type of TOS. To better understand these disorders, their distinctions, and the reasoning underlying the categorical change of disputed TOS from a form of TOS to a cervicoscapular pain syndrome, a thorough understanding of the pertinent anatomy, pathology, pathophysiology, and the electrodiagnostic manifestations of their pathophysiologies is required. This review of the TOSs is provided in 2 parts. In this first part we address information pertinent to all 5 TOSs and reviews true neurogenic TOS. In part 2 we review the other 4 TOSs.

    The effectiveness of operative treatment of paediatric thoracic outlet syndrome (TOS) has been analysed, and an attempt made to improve the definition of the condition in terms of presentation, aetiology and diagnosis. A retrospective review of postoperative pain, functional capability and overall outcome was carried out on 13 patients (poor. Mean functional improvement was good, and overall operative outcomes excellent. Therefore, surgery was successful for paediatric TOS in this series. Anatomical anomalies and sport participation may be related to early onset of TOS in many paediatric patients. Copyright © 2011 Elsevier Ltd. All rights reserved.

    By the 1980s, endoscopy was in use by some groups in sympathetic denervation of the upper limbs with vascular indications. Low morbidity, cosmetic results, reduction in the incidence of Horner syndrome, and the shortened time in hospital made video-assisted thoracic sympathectomy (VATS) better accepted by those undergoing treatment for hyperhidrosis. Over the last 25 years, this surgical procedure has become routine in the treatment of hyperhidrosis, leading to a significant increase in the number of papers on the subject in the literature.

    We report a rare case of primary thoracic rhabdomyosarcoma in a girl who was referred with acute chest pain, hacking cough, and wheezing. A chest X-ray revealed a complete opacity of the right hemithorax. Ultrasound revealed a right-sided pleural effusion and a solid mass above the liver dome, suggesting a neoplastic disease, which quickly led to further specific examination. Use of CT and MRI together with bone scintigraphy completed the investigation. The biopsy specimen showed a pattern of alveolar rhabdomyosarcoma. This case was reported to emphasize the role of US in the evaluation of a child with hemithorax opacity. (orig.)

    Full Text Available Abstract Introduction The consequences of bone metastasis are often devastating. Although the exact incidence of bone metastasis is unknown, it is estimated that 350,000 people die of bone metastasis annually in the United States. The incidence of local recurrences after mastectomy and breast-conserving therapy varies between 5% and 40% depending on the risk factors and primary therapy utilized. So far, a standard therapy of local recurrence has not been defined, while indications of resection and reconstruction considerations have been infrequently described. This case report reviews the use of sternectomy for breast cancer recurrence, highlights the need for thorough clinical and radiologic evaluation to ensure the absence of other systemic diseases, and suggests the use of serratus anterior muscle flap as a pedicle graft to cover full-thickness defects of the anterior chest wall. Case presentation We report the case of a 70-year-old Caucasian woman who was referred to our hospital for the management of a retrosternal mediastinal mass. She had undergone radical mastectomy in 1999. Computed tomography and magnetic resonance imaging revealed a 74.23 × 37.7 × 133.6-mm mass in the anterior mediastinum adjacent to the main pulmonary artery, the right ventricle and the ascending aorta. We performed total sternectomy at all layers encompassing the skin, the subcutaneous tissues, the right pectoralis major muscle, all the costal cartilages, and the anterior part of the pericardium. The defect was immediately closed using a 0.6 mm Gore-Tex cardiovascular patch combined with a serratus anterior muscle flap. Our patient had remained asymptomatic during her follow-up examination after 18 months. Conclusion Chest wall resection has become a critical component of the thoracic surgeon's armamentarium.

    Patients affected with intra-thoracic recurrences of primary or secondary lung malignancies after a first course of definitive radiotherapy have limited therapeutic options, and they are often treated with a palliative intent. Re-irradiation with stereotactic ablative radiotherapy (SABR) represents an appealing approach, due to the optimized dose distribution that allows for high-dose delivery with better sparing of organs at risk. This strategy has the goal of long-term control and even cure. Aim of this review is to report and discuss published data on re-irradiation with SABR in terms of efficacy and toxicity. Results indicate that thoracic re-irradiation may offer satisfactory disease control, however the data on outcome and toxicity are derived from low quality retrospective studies, and results should be cautiously interpreted. As SABR may be associated with serious toxicity, attention should be paid for an accurate patients' selection. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The Tikhoff-Linberg procedure was originally described more than 80 years ago as a limb-sparing surgical option for malignancies involving the shoulder girdle. However, involvement of the chest wall was a contraindication, consigning patients to either amputation or shoulder disarticulation. With the addition of prosthetic and autologous tissue reconstruction of the chest wall, this procedure is a viable option for an extended group of patients. The modified procedure offers an excellent functional result, leaving the patient with a fully functional arm and hand. Copyright © 2012 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    Colonic diverticular disease is a common illness, especially in the elderly population. It may be asymptomatic and cause chronic intestinal problems, colonic diverticular bleeding or inflammatory complications with considerable morbidity and mortality. We have attempted at finding factors that would help us identify patients with a higher risk of diverticulitis recurrence as well as patients with a higher likelihood of perforated diverticulitis. This retrospective study included all patients admitted to our surgical ward for inflammatory complications of diverticular disease between 2000 and 2012: 278 patients, 88 men and 190 women. We looked up the first attack of diverticulitis in our documentation as well as the relapses, if any, their number and course, and the time from the first attack to the relapse. We analyzed the influence of age, gender, comorbidities (diabetes mellitus, overweight, ischemic heart disease, chronic renal failure, gastroduodenal disease), nicotine abuse and medication (glucocorticoids and other immunosuppressive drugs, acetylsalicylic acid) on diverticulitis recurrence and its complicated course. We compared the results of conservative and surgical therapy. Statistical analysis was performed using Fishers exact test and Man-Whitney U tests. We did not demonstrate any statistically significant dependence of diverticulitis recurrence on age or gender. Colectomy (both acute and elective surgery) clearly decreases the likelihood of recurrence (p=0.00007). Comorbidities, nicotine abuse and medication were not associated with an increased risk of recurrence. Steroid and immunosuppressive drugs use was significantly associated with higher perforation rates, without impacting on the likelihood of recurrence. Regular smoking of cigarettes had no impact on recurrence or on its severity. We did not find any reliable indicator of recurrent diverticulitis. Age, gender, comorbidities, smoking and medication are not significant. Immunocompromised

    Most body wall injuries in small animals are caused by bite wounds or vehicular trauma. Penetrating gunshot wounds are less common. Bite wounds are characterized by massive trauma to the body wall with associated defects, but fewer internal injuries, whereas gunshot wounds are associated with a high number of internal injuries. Vehicular accident injuries are caused by blunt force trauma and can lead to both body wall defects and internal organ damage. Impalement injuries are rare and are typically associated with internal damage. Exploratory surgery, herniorrhaphy, and aggressive wound management are recommended in the treatment of these injuries.

    The incidence of thoracic injuries resulting from cardiopulmonary resuscitation (CPR) is not well characterized. We describe a case in which a CPR-associated atrial rupture was identified with ultrasound and successfully managed in the intensive care unit with a bedside thoracotomy and atrial repair. We then describe a systematic review with pooled data analysis of CPR-associated cardiovascular, pulmonary, pleural, and thoracic wall injuries. PubMed, Scopus, EMBASE, and Web of Science were searched to identify relevant published studies. Unpublished studies were identified by searching the Australian and New Zealand Clinical Trials Registry, World Health Organization International Clinical Trials Registry Platform, Cochrane Library, ClinicalTrials.gov, Current Controlled Trials, and Google. Inclusion criteria for the pooled analysis were any clinical or autopsy study in which (a) patients underwent cardiopulmonary resuscitation, (b) chest compressions were administered either manually or with the assistance of active compression-decompression devices, and (c) autopsy or dedicated imaging assessments were conducted to identify complications. Exclusion criteria for the pooled analysis were pre-clinical studies, case reports and abstracts. Nine-hundred twenty-eight potentially relevant references were identified. Twenty-seven references met inclusion criteria. A systematic review of the literature is provided with pooled data analysis. The incidence of reported CPR-associated cardiovascular and thoracic wall injuries varies widely. CPR with active compression-decompression devices has a higher reported incidence of cardiopulmonary injuries. Bedside ultrasound may be a useful adjunct to assess and risk-stratify patients to identify serious or life-threatening CPR-associated injuries. Published by Elsevier Ireland Ltd.

    Rupture of the aorta is much more common in Friesians compared with other breeds of horse. Rupture always occurs adjacent to the scar of the ligamentum arteriosum. Previous histological examination of ruptured aortic walls suggested the presence of an underlying connective tissue disorder. Therefore, the aim of the present study was to compare the structural characteristics of the tunica media of the mid-thoracic aorta, distant to the lesion, in warmblood and Friesian horses with and without thoracic aortic rupture. In unaffected Friesian horses, the thickness of the tunica media, as well as the percentage area comprised of collagen type I, were significantly higher compared with the warmblood horses, supporting the hypothesis of a primary collagen disorder in the Friesian horse breed. However, in the tunica media of the affected Friesian horses there was no significant wall thickening. Moreover, the percentage area comprised of elastin was significantly lower, while the percentage area comprised of smooth muscle was higher, compared with unaffected Friesian and warmblood horses. These lesions are suggestive of an additional mild elastin deficiency with compensatory smooth muscle cell hypertrophy in affected Friesians. Copyright © 2016. Published by Elsevier Ltd.

    Myxoinflammatory fibroblastic sarcoma (MIFS) is a recently defined rare tumor. It is mainly found in the upper and lower extremities of adults. Due to its high local recurrence rate and low metastatic rate, it is classified as a low grade-malignancy. Accurate diagnosis and early, wide excision are important for prognosis. Herein, we report a case of MIFS in a 35-year-old male patient that presented in an unusual location, the left chest wall. To our knowledge, this is the first reported case of MIFS in Korea and the second case to be reported within the global scientific literature involving the chest wall.

    We present a case of an elderly non-smoking gentleman who, since 2005, had been admitted multiple times for recurrent episodes of shortness of breath, wheeze, cough and sputum. The patient was treated as exacerbations of chronic obstructive pulmonary disease (COPD) and\\/or lower respiratory tract infections. Bronchoscopy was done which revealed multiple hard nodules in the trachea and bronchi with posterior tracheal wall sparing. Biopsies confirmed this as tracheopathia osteochondroplastica (TO). He had increasing frequency of admission due to methicillin-resistant Staphylococcus aureus and pseudomonas infections, which failed to clear despite intravenous, prolonged oral and nebulised antibiotics. The patient developed increasing respiratory distress and respiratory failure. The patient died peacefully in 2012. This case report highlights the typical pathological and radiological findings of TO and the pitfalls of misdiagnosing patients with recurrent chest infections as COPD.

    Objective: An elevated total plasma homocysteine level has been suggested as a possible risk factor in women suffering from recurrent pregnancy loss. The current study was undertaken to assess the association between homocysteine, folate, cobalamin (vitamin B12) and the risk of recurrent pregnancy loss. Design: Case . control study Materials and Methods: The study included 57 non-pregnant Egyptian women. They were classified according to their obstetric history into 2 groups: 32 cases with at least two consecutive miscarriages (Study group), and 25 cases with normal obstetric history (Control group). All cases were tested for plasma total homocysteine, serum folate and cobalamin (vitamin B12). Results: The fasting total homocysteine was significantly higher in the study group as compared to the control group. While the median concentrations for the vitamins studied were significantly lower in women of the study group as compared to the controls. Elevated homocysteine and reduced vitamin B12 can be considered risk factors for recurrent miscarriage with odds ratio (OR) and 95% confidence intervals (95% CI) of 1.839 (1.286, 2.63) and 1.993 (1.346, 2.951) respectively in the group of recurrent miscarriages. The OR (95% CI) in the study population for low serum folate concentrations was 1.23 (0.776, 2.256). Conclusion: Elevated homocysteine and reduced serum vitamin B12 are risk factors for recurrent miscarriage. Low serum folate did not seem a risk factor for recurrent miscarriage. Testing for homocysteine levels in women suffering from unexplained recurrent miscarriage and pre-conceptional supplementation with vitamin B12 might be beneficial to improve pregnancy outcome

    Intradural epidermoid tumors of the spinal cord are commonly associated with spinal cord dysraphism or invasive procedures. We report the particular relationships between spinal subarachnoid compartments and thoracic intradural-extramedullary epidermoid tumor, highlighting the relevant anatomic changes that may influence microsurgery. A 40-year-old woman from compressive myelopathy owing to a thoracic epidermoid tumor extending from T3 to T4 and not associated with spina bifida, trauma, previous surgery, or lumbar spinal puncture underwent microsurgical excision. Accurate tumor membrane dissection, respecting spinal arachnoidal compartments, was performed. Reposition of a laminoplasty plateau helped in restoring thoracic spine anatomic integrity. Safe gross total tumor resection was achieved. Complete neurologic recovery as well as absence of recurrent tumor was documented at 4-year follow-up. A literature review revealed only 2 other cases of "isolated" thoracic spine epidermoid tumor. However, description of the relationship between tumor membranes and spinal subarachnoid compartments was not available in either case. A thorough knowledge of spinal subarachnoid space anatomy is helpful to distinguish between tumor membranes and arachnoidal planes and to achieve a safe and complete resection to avoid recurrences.

    Full Text Available Introduction - Most often, ganglioneuromas affect older pediatric and adult patients. They are typically slow growing tumors that remain clinically silent until they become large enough to cause symptoms by compression of adjacent structures. Case - We report a case of a 22-year-old Hispanic gravida 2 para 1 female patient who was found to have massive hydrops fetalis at 20 completed gestational weeks. Fetal echocardiography revealed a narrowed distal ductal arch and proximal descending aorta. Cesarean delivery was undertaken at 29 completed gestational weeks for refractory labor and nonreassuring fetal status. The neonate expired at 47 minutes of life despite aggressive resuscitation. At autopsy, multiple thoracic masses were found adjacent to a compressed proximal descending aorta. Histological and immunohistochemical analysis confirmed the diagnosis of a ganglioneuroma, a rare type of neural crest tumor. Discussion - A variety of intrathoracic masses have previously been reported to cause hydrops fetalis including teratomas, fibrosarcomas, and lymphangiomas. To our knowledge, this case is the first description of hydrops fetalis caused by ganglioneuromas. We propose that multiple thoracic ganglioneuromas led to biventricular distal outflow tract obstruction and hydrops fetalis.

    Retrospective clinical study. To evaluate the results of a new method of laminoplasty, referred to as conical laminoplasty. In surgery for a thoracic intradural tumor, laminectomy is frequently used for tumor resection. However, laminoplasty may be more effective due to prevention of damage to the posterior elements. This method can be performed as recapping T-saw laminoplasty and conical laminoplasty which we refer. After en bloc laminectomy, conical laminoplasty (group C; 21 cases) or recapping T-saw laminoplasty (group R; 17 cases) was performed for patients with thoracic spinal cord tumors. If neither was possible, laminectomy (group L; 16 cases) was performed. The number of laminae removed and Japanese Orthopedic Association recovery rates did not differ significantly among the 3 groups. Sagittal kyphosis significantly worsened at final follow-up in group L, but did not change significantly in groups C and R. Conical laminoplasty is particularly useful in a case in which T-saw laminoplasty cannot be performed due to tumor expansion in the canal and ossification of the ligamentum flavum. Conical laminoplasty also preserves the posterior elements, which reduces the risk of worsening of kyphosis postoperatively.

The aim of this study was to determine the success of selective nonoperative management (SNOM) of patients presenting with a penetrating thoracic injury (PTI). This was a prospective study of patients with PTI who presented to a level 1 Trauma Center between April 2012 and August 2012. A total of 248 patients were included in the study, with 5.7% (n=14) requiring immediate emergency surgery. Overall, five of these 248 patients died, resulting in a mortality rate of 2.0%. Primarily 221 patients (89.1%) were managed with SNOM, of whom 15 (6.8%) failed conservative management. Failure of SNOM was primarily caused by complications of chest tube drainage (n=12) (e.g. retained clot, empyema) and delayed development of cardiac tamponade (n=3). The survival rate in the SNOM group was 100%. PTI has a low in-hospital mortality rate. Only 16.5% (41/248) of the patients presenting with PTI will need surgical treatment. The other patients are safe to be treated conservatively according to a protocolized SNOM approach for PTI without any additional mortality. Conservative treatment of patients who were selected for this nonoperative treatment strategy with repeated clinical reassessment was successful in 93.2%.

    Full Text Available Background: Respiratory problems are usual in upper thoracic spinal cord injuries when compared to Lower thoracic spinal cord injuries. Generally there are frequent respiratory complications in the individuals with spinal cord injuries. The complications of the respiratory system are severe and more prevalent source of morbidity and mortality after the spinal cord injury due to the inefficient breathing capacity including inspiratory and expiratory abilities. The present study represents the inspiratory muscle training especially in upper thoracic spinal cord injury patients to assess the improvement in the pulmonary functions. Methods: Twenty five patients with the age between 25 -40 years with the upper spinal cord injuries were selected in the present study in order to assess the efficacy of the training. Several types of exercises were practiced including diaphragmatic breathing exercises, incentive spirometry, active cycle of breathing technique and weight training. COPD Conditions, Chest wall deformities, Hypertensive patients, Cardio vascular problems were excluded in the study. Results: The results from the study showed that significant changes were found in the patients treated with all the above mentioned techniques. Axillary level, nipple level, Xiphisternum levels were analysed and the results found to be significant after the treatment. Incentive spirometry and peak flow meter observations were also found to be significant when compare to the pretreatment. Conclusion: The present study conclude that the combined effect of incentive spriometry, diaphragmatic breathing exercises, and active cycle of breathing technique is more effective in improving the pulmonary functions in upper thoracic spinal cord injuries than single method efficiency.

    Full Text Available Chest wall defect may be caused by many factors such as the resection of tumor and trauma, and the reconstruction of bone-defection is still the key point of thoracic surgery. With the development of material science, more and more new materials have been used in medical practice, which makes huge progress in the surgery of chest wall. However, none of these materials satisfy all the practical needs of the reconstruction. Recently, with the development of the capacity of computer, 3D-printing technology has been gradually used in clinical work, and the idea of individual treatment has been accepted by more and more people. The weakness of these materials may be solved by the new material and the application of individual treatment, which could also make great advance in chest wall surgery. This article will make a summary of the research on the reconstruction of chest wall.

  6. Recurrences of Bell's palsy.

    Bell's palsy in known as the most common cause of facial paralysis, determined by the acute onset of lower motor neuron weakness of the facial nerve with no detectable cause. With a lifetime risk of 1 in 60 and an annual incidence of 11-40/100,000 population, the condition resolves completely in around 71% of the untreated cases. Clinical trials performed for Bell's palsy have reported some recurrences, ipsilateral or contralateral to the side affected in the primary episode of facial palsy. Only few data are found in the literature. Melkersson-Rosenthal is a rare neuromucocutaneous syndrome characterized by recurrent facial paralysis, fissured tongue (lingua plicata), orofacial edema. We attempted to analyze some clinical and epidemiologic aspects of recurrent idiopathic palsy, and to develop relevant correlations between the existing data in literature and those obtained in this study. This is a retrospective study carried out on a 10-years period for adults and a five-year period for children. A number of 185 patients aged between 4 and 70 years old were analyzed. 136 of them were adults and 49 were children. 22 of 185 patients with Bell's palsy (12%) had a recurrent partial or complete facial paralysis with one to six episodes of palsy. From this group of 22 cases, 5 patients were diagnosed with Melkersson-Rosenthal syndrome. The patients' age was between 4 and 70 years old, with a medium age of 27,6 years. In the group studied, fifteen patients, meaning 68%, were women and seven were men. The majority of patients in our group with more than two facial palsy episodes had at least one episode on the contralateral side. Our study found a significant incidence of recurrences of idiopathic facial palsy. Recurrent idiopathic facial palsy and Melkersson-Rosenthal syndrome is diagnosed more often in young females. Recurrence is more likely to occur in the first two years from the onset, which leads to the conclusion that we should have a follow up of patients

    Children presenting with recurrent fever may represent a diagnostic challenge. After excluding the most common etiologies, which include the consecutive occurrence of independent uncomplicated infections, a wide range of possible causes are considered. This article summarizes infectious and noninfectious causes of recurrent fever in pediatric patients. We highlight that, when investigating recurrent fever, it is important to consider age at onset, family history, duration of febrile episodes, length of interval between episodes, associated symptoms and response to treatment. Additionally, information regarding travel history and exposure to animals is helpful, especially with regard to infections. With the exclusion of repeated independent uncomplicated infections, many infective causes of recurrent fever are relatively rare in Western countries; therefore, clinicians should be attuned to suggestive case history data. It is important to rule out the possibility of an infectious process or a malignancy, in particular, if steroid therapy is being considered. After excluding an infectious or neoplastic etiology, immune-mediated and autoinflammatory diseases should be taken into consideration. Together with case history data, a careful physical exam during and between febrile episodes may give useful clues and guide laboratory investigations. However, despite a thorough evaluation, a recurrent fever may remain unexplained. A watchful follow-up is thus mandatory because new signs and symptoms may appear over time.

    This study was designed to evaluate the feasibility of video-assisted thoracoscopic surgery (VATS) and to compare the oncologic outcomes of VATS with those of sternotomy in patients with thymoma. The clinical outcomes of 2,835 patients with thymic epithelial tumors treated between 1991 and 2010 in 32 Japanese institutions were collected retrospectively. The study compared postoperative complications, positive surgical margins, location of recurrence, and survival in 140 of 142 VATS-treated patients (VATS group) matched with 140 of 1,294 sternotomy-treated patients (ST group) by using propensity scores. Postoperative complications were observed in 8 patients in the VATS group. The morbidity rate in the VATS group was not different from that of the ST group (p = 0.25). Positive surgical margins were noted in 4 patients (3 in the VATS group; 1 in the ST group). There was no statistically significant difference in the recurrence rate between groups (median follow-up period: 3.7 years in the VATS group; 5.2 years in the ST group). In total the most frequent site of recurrence was pleural dissemination. In the VATS group, the 5-year recurrence-free survival rate was 93.8%, and the 5-year overall survival rate was 97.9%. There was no difference in the recurrence-free survival and overall survival rates between the VATS group and the ST group (p = 0.91 and p = 0.74, respectively). VATS thymectomy was feasible and comparable to sternotomy for the treatment of patients with thymoma with regard to morbidity, incomplete resection rate, and prognosis. However, additional follow-up is required to evaluate long-term outcomes. Copyright © 2017 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    2017-11-01

    Full Text Available The cause of serious and fatal thoracic injuries in passenger vehicle rollover crashes is currently not well understood. Previous research on thoracic injuries resulting from rollover crashes have focused primarily on statistical analysis of crash data. This study seeks to develop a better understanding of where in the rollover sequence thoracic injuries may occur. To do this, a real-world passenger vehicle rollover crash where the driver sustained serious bilateral thoracic injuries was reconstructed. Multi-body analysis was used to determine the vehicle’s pre-trip trajectory and to obtain the vehicle’s position and kinematics at the point of trip. This information was then used to prescribe the motion of the vehicle in a finite element analysis. A finite element model of the EuroSID-2re anthropomorphic test device was placed in the driver’s seat. Four simulations, each with the anthropomorphic test device positioned in different postures, were performed. Rib deflection, spinal acceleration, and thoracic impact velocity were obtained from the anthropomorphic test device and compared to existing thoracic injury assessment reference values. From the analysis, lateral thoracic impact velocity indicates that a serious thoracic injury is likely to have occurred when the driver impacted the centre console during the vehicle’s fourth quarter-turn.

  2. Recurrent Obstructive Fibrinous Tracheal Pseudomembranes in a Young English Bulldog.

    Robin, E; Guieu, L V; Le Boedec, K

    2017-03-01

    Endotracheal intubation is a common procedure, rarely associated with life-threatening complications (e.g., tracheal rupture, necrosis, foreign body). A 1.5-year-old English Bulldog was presented for respiratory distress, with increased respiratory efforts and stridor, 2 days after endotracheal intubation. Cervical and thoracic radiographs disclosed a severe narrowing of the tracheal lumen associated with an intraluminal soft-tissue structure at the thoracic inlet. Tracheoscopy confirmed the presence of an obstructive fibrinous tracheal pseudomembrane (OFTP) creating a 1-way valve obstruction. Removal of the OFTP dramatically improved the dog's respiratory function, but the lesion reformed twice despite corticosteroid and antibiotic therapy PO, warranting repeated endoscopic removal of the OFTP. No additional recurrences were observed after treatment with inhaled heparin and N-acetylcysteine q4h. No respiratory signs were reported 9 months after discharge. Postintubation OFTP has been reported rarely in humans and never described in dogs. Unexplained signs of upper airway obstruction shortly after endotracheal intubation should prompt consideration of OFTP in dogs, even if intubation was uneventful. Unlike its counterpart in humans, OFTP in dogs can reoccur after endoscopic removal, warranting repeated endoscopic extraction. A combination of corticosteroid therapy PO and heparin and N-acetylcysteine inhalation q4h may be attempted if recurrence is observed. Copyright © 2017 The Authors.

    2016-08-01

    Lumbo-costo-vertebral syndrome (LCVS) is a rare disorder in children that is characterized by hemivertebrae, congenital absence of ribs, meningocele, and hypoplasia of the truncal and abdominal wall presenting as a congenital lumbar hernia. An otherwise healthy 12-month-old girl was referred to the authors' hospital with soft swelling on her left middle back; scoliosis had been present since birth. Imaging revealed a thoracic meningocele, ectopia of the spleen suggesting lumbar hernia, multiple anomalies of the thoracic vertebral columns, and defects of the ribs; thus, LCVS was diagnosed. Surgical observation revealed that the meningocele was firmly anchored to part of the diaphragm, which created stretching tension in the meningocele continuously with exhalation. Once detached, the meningocele shrank spontaneously and never developed again after cauterization. In this case, continuous or pulsatile pressure in the presence of a vertebral defect was thus considered to be an important factor for formation of the thoracic meningocele.

    Breast sarcoma during pregnancy is an extremely rare event and represents a complex problem because of a more advanced stage at presentation. This report presents the first case of a 24-year-old woman with a gestational age of 20 weeks with a fast growing tumour in her left breast (29 × 19 × 15 cm) and infiltrating the skin/pectoralis muscles. Radical mastectomy was performed with a gestational age of 22 weeks and a different design was planned for the latissimus dorsi musculocutaneous flap (LDMF) with primary closure in the V-Y pattern. Satisfactory chest wall coverage and contour were achieved. Final histopathological findings allowed a diagnosis of undifferentiated sarcoma. With a gestational age of 37 weeks, a healthy infant was delivered by means of a caesarean section. The patient is currently in the second postoperative year and no recurrence has been observed. Management of a large breast sarcoma in a pregnant patient presents unique challenges in consideration of the potential risks to the foetus and the possible maternal benefit. The results of this study demonstrate that the VY-LDMF is a reliable technique and should be considered in cases of immediate large thoracic wound reconstruction.

    The aim of this narrative review is to update the current knowledge on the treatment of recurrent cervical cancer based on a literature review. A web based search in Medline and CancerLit databases has been carried out on recurrent cervical cancer management and treatment. All relevant information has been collected and analyzed, prioritizing randomized clinical trials. Cervical cancer still represents a significant problem for public health with an annual incidence of about half a million new cases worldwide. Percentages of pelvic recurrences fluctuate from 10% to 74% depending on different risk factors. Accordingly to the literature, it is suggested that chemoradiation treatment (containing cisplatin and/or taxanes) could represent the treatment of choice for locoregional recurrences of cervical cancer after radical surgery. Pelvic exenteration is usually indicated for selected cases of central recurrence of cervical cancer after primary or adjuvant radiation and chemotherapy with bladder and/or rectum infiltration neither extended to the pelvic side walls nor showing any signs of extrapelvic spread of disease. Laterally extended endopelvic resection (LEER) for the treatment of those patients with a locally advanced disease or with a recurrence affecting the pelvic wall has been described. The treatment of recurrences of cervical carcinoma consists of surgery, and of radiation and chemotherapy, or the combination of different modalities taking into consideration the type of primary therapy, the site of recurrence, the disease-free interval, the patient symptoms, performance status, and the degree to which any given treatment might be beneficial.

    Isolated locoregional recurrences (ILRRs) of breast cancer confer a significant risk for the development of distant metastasis. Management practices and second ILRR events in the Chemotherapy as Adjuvant for LOcally Recurrent breast cancer (CALOR) trial were investigated. In this study, 162 patients with ILRR were randomly assigned to receive postoperative chemotherapy or no chemotherapy. Descriptive statistics characterize outcomes according to local therapy and the influence of hormone receptor status on subsequent recurrences. Competing risk regression models, Kaplan-Meier estimates, and Cox proportional hazards models were used to evaluate associations between treatment, site of second recurrence, and outcome. The median follow-up period was 4.9 years. Of the 98 patients who received breast-conserving primary surgery 89 had an ipsilateral-breast tumor recurrence. Salvage mastectomy was performed for 73 patients and repeat lumpectomy for 16 patients. Another eight patients had nodal ILRR, and one patient had chest wall ILRR. Among 64 patients whose primary surgery was mastectomy, 52 had chest wall/skin ILRR, and 12 had nodal ILRR. For 15 patients, a second ILRR developed a median of 1.6 years (range 0.08-4.8 years) after ILRR. All second ILRRs occurred for patients with progesterone receptor-negative ILRR. Death occurred for 7 (47 %) of 15 patients with a second ILRR and 19 (51 %) of 37 patients with a distant recurrence. As shown in the multivariable analysis, the significant predictors of survival after either a second ILRR or distant recurrence were chemotherapy for the primary cancer (hazard ratio [HR], 3.55; 95 % confidence interval [CI], 1.15-10.9; p = 0.03) and the interval (continuous) from the primary surgery (HR, 0.87; 95 % CI, 0.75-1.00; p = 0.05). Second ILRRs represented about one third of all recurrence events after ILRR, and all were PR-negative. These second ILRRs and distant metastases portend an unfavorable outcome.

    2015-01-01

    Respiratory and cardiac motion leads to image degradation in Positron Emission Tomography (PET), which impairs quantification. In this book, the authors present approaches to motion estimation and motion correction in thoracic PET. The approaches for motion estimation are based on dual gating and mass-preserving image registration (VAMPIRE) and mass-preserving optical flow (MPOF). With mass-preservation, image intensity modulations caused by highly non-rigid cardiac motion are accounted for. Within the image registration framework different data terms, different variants of regularization and parametric and non-parametric motion models are examined. Within the optical flow framework, different data terms and further non-quadratic penalization are also discussed. The approaches for motion correction particularly focus on pipelines in dual gated PET. A quantitative evaluation of the proposed approaches is performed on software phantom data with accompanied ground-truth motion information. Further, clinical appl...

  8. Impedance plethysmography of thoracic region: impedance cardiography.

    1990-10-01

    Full Text Available Impedance plethysmograms were recorded from thoracic region in 254 normal subjects, 183 patients with coronary artery disease, 391 patients with valvular heart disease and 107 patients with congenital septal disorder. The data in 18 normal subjects and 55 patients showed that basal impedance decreases markedly during exercise in patients with ischaemic heart disease. Estimation of cardiac index by this technique in a group of 99 normal subjects has been observed to be more consistent than that of the stroke volume. Estimation of systolic time index from impedance plethysmograms in 34 normal subjects has been shown to be as reliable as that from electrocardiogram, phonocardiogram and carotid pulse tracing. Changes in the shape of plethysmographic waveform produced by valvular and congenital heart diseases are briefly described and the role of this technique in screening cardiac patients has been highlighted.

    1990-07-01

    Full Text Available Forty patients with symptoms of neuro-vascular compression in the upper extremities were subjected to impedance plethysmographic study using Parulkar′s method. Two patients recorded decreased blood flow (BFI in supine position and were diagnosed as having partial occlusion at subclavian level. Sixteen of the patients recorded decreased BFI on 90 degrees abduction and hyper-abduction. Twelve of these patients had radiological evidence of anomalous cervicle ribs. In remaining four patients extrinsic impression on the subclavian artery due to fibrous deposits was confirmed by arteriography. Remaining 22 patients recorded normal impedance plethysmograms. Impedance plethysmography thus provided a non-invasive modality for confirmation of vascular compression in thoracic outlet syndrome.

  10. Telomere Biology and Thoracic Aortic Aneurysm

    2017-12-01

    Full Text Available Ascending aortic aneurysms are mostly asymptomatic and present a great risk of aortic dissection or perforation. Consequently, ascending aortic aneurysms are a source of lethality with increased age. Biological aging results in progressive attrition of telomeres, which are the repetitive DNA sequences at the end of chromosomes. These telomeres play an important role in protection of genomic DNA from end-to-end fusions. Telomere maintenance and telomere attrition-associated senescence of endothelial and smooth muscle cells have been indicated to be part of the pathogenesis of degenerative vascular diseases. This systematic review provides an overview of telomeres, telomere-associated proteins and telomerase to the formation and progression of aneurysms of the thoracic ascending aorta. A better understanding of telomere regulation in the vascular pathology might provide new therapeutic approaches. Measurements of telomere length and telomerase activity could be potential prognostic biomarkers for increased risk of death in elderly patients suffering from an aortic aneurysm.

    2010-03-01

    We report a case of thoracic (T10) spinal cord compression by a tophus in a patient with known chronic gout. Spastic paraplegia developed gradually over 6 months in this 43-year-old man with hypertension, alcohol abuse, and chronic gouty arthritis with tophi. Magnetic resonance imaging and computed tomography visualized an intradural nodule measuring 1.5cm in diameter at the level of T10, as well as geodes in the left T10 lamina and left T9-T10 articular processes. The nodule was removed surgically and shown by histological examination to be a tophus. The neurological impairments resolved rapidly and completely.

    2014-01-01

    Full Text Available Introduction: Multiple case reports and reviews have been described in the literature for bladder wall leiomyoma resection via different approaches. The minimally invasive partial cystectomy remains the most widely accepted technique; however, case reports for enucleation of bladder wall leiomyoma have also been described. The purpose of this video is to demonstrate the robotic extramucosal excision of a bladder wall leiomyoma, without cystotomy, but with complete removal of the muscular layer. Materials and Methods: A 35-year old male present with lower urinary tract symptoms and imaging showed bladder wall mass with histopathology showed leiomyoma. The patient consented for mass excision with the possibility of a partial cystectomy. The patient was placed in the supine, 30-degree Trendelenburg position during the procedure. A total of 4 ports were inserted. A 3-arm da Vinci robotic surgical system was docked, and the arms were connected. Extramucosal excision was accomplished without cystotomy and muscle approximation was achieved by 2 0 Vicryle. Result: The operative time was 90 minutes, blood loss of approximately 50mL and the patient was discharged after 72 hours with no immediate complications and a 6 months follow-up showed no recurrence. Conclusion: Such a technique results in complete excision of the tumor, without cystotomy, and also maintains an intact mucosa. These steps, in addition to decreasing the risk of local recurrence, also shorten the period of postoperative catheterization and hospitalization.

    2015-04-01

    A 59-year-old woman was admitted three times over a six-month period with recurrent upper extremity deep venous thrombosis (UEDVT). It was determined that this patient was suffering from an unusual presentation of Paget-Schröetter syndrome secondary to a 20-year-old non-union of a midshaft clavicle fracture. Following thrombolysis the patient underwent resection and plate fixation of the clavicle fracture non-union. Despite the anatomic proximity of the subclavian vessels to the clavicle, vascular complications from fracture are rare. Treatment of midshaft clavicle fractures is often non-operative. Non-union rates are generally less than 10%, and easily treated secondarily without complication. Clavicular pseudo-arthroses from trauma have been implicated in the development of the thoracic outlet syndromes, however, onset 20 years after fracture has never before been reported. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    2010-05-01

    We successfully performed 1-port video-assisted thoracic surgery (VATS) for primary spontaneous pneumothorax using Mini Loop Retractor II in 137 (39%) of 351 patients from March 2005 to May 2009 at Tokyo Teishin Hospital. This retractor is accessible to the thoracic cavity by simple skin puncture. It can hold and retract the lung freely like forceps. We made a 2 cm incision and inserted a 5 mm thoracoscope. We held the affected lung by the retractor and performed wedge resection by endoscopic staplers through skin incision. The operation time was 34.8 +/- 10.9 minutes and the blood loss was trace level in all cases. The duration of chest drainage was 1.2 +/- 0.8 days and the postoperative hospital stay was 2.8 +/- 1.2 days. There was no major complications. The recurrence of pneumothorax was noted in 17 (12.4%) cases. One-port VATS for pneumothorax using Mini Loop Retractor II can be applied easily and safely to selected patients.

    Hyperhidrosis is secondary to over activation of the sympathetic nervous system and surgical sympathectomy is the treatment of choice when other modalities have failed. This study investigated anatomic variation in the upper thoracic sympathetic chain and associated rami communicantes among cadaveric specimens. It considers the implications of these findings on surgical techniques to treat hyperhidrosis. The upper 4 thoracic sympathetic ganglia, intercostal nerves, and connecting rami were dissected, measured and mapped in 40 sides of 20 adult human cadavers. Ganglia location was recorded. The incidence, orientation, and distance travelled by rami communicantes was compared across different ganglionic levels and between sides. The percentage of ganglia located below their associated intercostal space was 6.25% with stellate ganglions present in 70% of specimens and Kuntz fibers noted in 40%. There was a stepwise reduction in incidence of rami from superior to inferior placed ganglia. The number of rami identified across all levels was significantly greater on the right (P = 0.03). The horizontal distance between the sympathetic chain and union of the rami on the intercostal nerves was significantly greater on the right across all levels (P = 0.04). There was substantial variation in the rami communicantes across the upper 4 ganglia and between right and left sides. Consideration of this variation should be given when planning surgical sympathectomy for hyperhidrosis particularly to avoid symptom recurrence. Copyright © 2016 Elsevier Inc. All rights reserved.

    Maintenance of the structure and mechanical properties of the thoracic aorta contributes to aortic function and is dependent on the composition of the extracellular matrix and the cellular content within the aortic wall. Age-related alterations in the aorta include changes in cellular content and composition of the extracellular matrix; however, the precise roles of these age-related changes in altering aortic mechanical function are not well understood. Thoracic aortic rings from the descending segment were harvested from C57BL/6 mice aged 6 and 21 months. Thoracic aortic diameter and wall thickness were higher in the old mice. Cellular density was reduced in the medial layer of aortas from the old mice; concomitantly, collagen content was higher in old mice, but elastin content was similar between young and old mice. Stress relaxation, an index of compliance, was reduced in aortas from old mice and correlated with collagen fraction. Contractility of the aortic rings following potassium stimulation was reduced in old versus young mice. Furthermore, collagen gel contraction by aortic smooth muscle cells was reduced with age. These results demonstrate that numerous age-related structural changes occurred in the thoracic aorta and were related to alterations in mechanical properties. Aortic contractility decreased with age, likely because of a reduction in medial cell number in addition to a smooth muscle contractile deficit. Together, these unique findings provide evidence that the age-related changes in structure and mechanical function coalesce to provide an aortic substrate that may be predisposed to aortopathies. © 2015 The Authors.

    Menopause would seem to exist as a period of accelerated changes for women and their upper torso mechanics. Whether these anthropometric changes reflect changes in pain states remains unclear. Plausible mechanisms of pain exist for the independent and combined effect of increasing breast size and thoracic kyphosis. Bra fit has the potential to change when the anthropometric measures (chest circumference and bust circumference) used to determine bra size change, such as postmenopausally.Identifying an association between breast size, thoracic kyphosis and thoracic spine pain in postmenopausal women and identifying the relevance of bra fit to this association may be of importance to the future management and education of post-menopausal women presenting clinically with thoracic spine pain. A cross-sectional study design. Fifty-one postmenopausal bra-wearing women were recruited. Measures included breast size (Triumph International), thoracic kyphosis (flexible curve), bra fitted (Y/N) and pain (Short Form McGill Pain Questionnaire) and tenderness on palpation (posteroanterior pressure testing). These measures were collected in one session at a physiotherapy clinic. The majority of the women in this study were overweight or obese and wearing an incorrect sized bra. Pain was significantly related to breast size, body weight and BMI at mid thoracic levels (T7-8). In contrast self-reported thoracic pain was not correlated with age or index of kyphosis (thoracic kyphosis). Women with thoracic pain were no more likely to have their bra professionally fitted whereas women with a higher BMI and larger breasts were more likely to have their bra professionally fitted. The findings of this study show that larger breasts and increased BMI are associated with thoracic pain in postmenopausal women. This is unrelated to thoracic kyphosis. Increasing breast size and how a bra is worn may have biomechanical implications for the loaded thoracic spine and surrounding musculature. Post

  8. Robotic thoracic surgery: The state of the art

    Minimally invasive thoracic surgery has come a long way. It has rapidly progressed to complex procedures such as lobectomy, pneumonectomy, esophagectomy, and resection of mediastinal tumors. Video-assisted thoracic surgery (VATS) offered perceptible benefits over thoracotomy in terms of less postoperative pain and narcotic utilization, shorter ICU and hospital stay, decreased incidence of postoperative complications combined with quicker return to work, and better cosmesis. However, despite its obvious advantages, the General Thoracic Surgical Community has been relatively slow in adapting VATS more widely. The introduction of da Vinci surgical system has helped overcome certain inherent limitations of VATS such as two-dimensional (2D) vision and counter intuitive movement using long rigid instruments allowing thoracic surgeons to perform a plethora of minimally invasive thoracic procedures more efficiently. Although the cumulative experience worldwide is still limited and evolving, Robotic Thoracic Surgery is an evolution over VATS. There is however a lot of concern among established high-volume VATS centers regarding the superiority of the robotic technique. We have over 7 years experience and believe that any new technology designed to make minimal invasive surgery easier and more comfortable for the surgeon is most likely to have better and safer outcomes in the long run. Our only concern is its cost effectiveness and we believe that if the cost factor is removed more and more surgeons will use the technology and it will increase the spectrum and the reach of minimally invasive thoracic surgery. This article reviews worldwide experience with robotic thoracic surgery and addresses the potential benefits and limitations of using the robotic platform for the performance of thoracic surgical procedures.

    Thoracic pedicle screws have superior anchoring strength compared with other available fixation techniques. However, these are not universally accepted in many developing countries because of the concerns regarding safety and complications. In addition, there is evidence that pedicle morphology is unique in Chinese patients. The goal of this study was to analyze the complications seen at our institution, while using thoracic pedicle screws for the treatment of thoracic deformity, and to determine the safety of our techniques for the treatment of thoracic deformity in a Chinese population. From 1998 to 2005, there were 208 thoracic deformity patients treated at our institution, 70 of whom were male and 138 were female. Their age ranged from 11 to 55 years (mean of 14.9 years). All of them underwent corrective deformity surgery using posterior pedicle screw systems and follow-up was available for at least 3 years. Etiologic diagnoses included adolescent idiopathic scoliosis in 119 patients, congenital kyphoscoliosis in 38, adult scoliosis in 37 and undetermined in 14. Screw positions were evaluated using intraoperative and postoperative radiographs and a CT scan was performed when a concern for screw malposition was present. All radiographic evaluations were carried out in a double-blinded fashion. A total of 1,123 thoracic pedicle screws were inserted (5.4 thoracic screws/patient). The deformity correction rate was 81, 65 and 62% for idiopathic, congenital and adult scoliosis patients, respectively. The overall complication rate was 16.5% at the final follow-up. Complication rates directly and indirectly related to pedicle screws were 7.2 and 9.3%, respectively. There were no significant screw-related neurologic or visceral complications that adversely affected long-term results. The complications seen with thoracic pedicle screws in a Chinese population were similar to other populations and could be utilized safely for the treatment of thoracic deformity in this

    The authors have transcutaneously implanted I-125 radioactive seeds in six patients with thoracic tumors (three with lung cancer; three with metastases) to determine the feasibility of this procedure. In four patients the thoracic tumors were localized without evidence of distant metastases, but these patients were not candidates for resection because of chronic pulmonary disease. Tumor volume was measured on CT scans (with sagittal and coronal reconstructions) and the required number of seeds was determined based on tumor volume. Between 6 and 11 needles were placed in the tumor and the seeds were implanted as the needle was withdrawn. Between 40 and 60 seeds were implanted in each patient, under local anesthesia. In this preliminary series all patients were found to have tumor attached to pleura. Four of the six patients underwent implantation during a day-time admission to the institution's Adult Day Hospital. No patient suffered any complication as a result of the procedure. Four patients experienced a symptomatic relief of pain and a decrease in size of tumor bulk (local control). Two patients eventually exhibited renewed tumor growth in the edges of the implanted mass after 6 months; the authors plan to supplement future implantations with external radiation therapy. One patient underwent implantation after local recurrence of tumor, returned to work the day following the procedure, and is without evidence of local recurrence 18 months later. They are encouraged by these preliminary results, for several reasons: the lack of morbidity, the achievement of local control of tumor while avoiding surgery and its potential complications, and avoidance of hospital stay (with consequent financial savings). The intent is to expand this series to include patients with lung tumors not attached to pleura

    Thoracic outlet syndrome (TOS) refers to the compression of the neurovascular bundle within the thoracic outlet. Cases are classified by primary etiology-arterial, neurogenic, or venous. In addition to the typical symptoms of arm swelling and paresthesias, headaches have been reported as a potential symptom of TOS. In this report, we describe a patient with debilitating migraines, which were consistently preceded by unilateral arm swelling. Resolution of symptoms occurred only after thoracic outlet decompression. Patients with migraines and concomitant swelling and/or paresthesias, especially related to provocative arm maneuvers, should be considered a possible atypical presentation of TOS and evaluated in more detail.

    2016-01-01

    Purpose: Stereotactic ablative radiation therapy (SABR) is a guideline-specified treatment option for early-stage lung cancer. However, significant posttreatment fibrosis can occur and obfuscate the detection of local recurrence. The goal of this study was to assess physician ability to detect timely local recurrence and to compare physician performance with a radiomics tool. Methods and Materials: Posttreatment computed tomography (CT) scans (n=182) from 45 patients treated with SABR (15 with local recurrence matched to 30 with no local recurrence) were used to measure physician and radiomic performance in assessing response. Scans were individually scored by 3 thoracic radiation oncologists and 3 thoracic radiologists, all of whom were blinded to clinical outcomes. Radiomic features were extracted from the same images. Performances of the physician assessors and the radiomics signature were compared. Results: When taking into account all CT scans during the whole follow-up period, median sensitivity for physician assessment of local recurrence was 83% (range, 67%-100%), and specificity was 75% (range, 67%-87%), with only moderate interobserver agreement (κ = 0.54) and a median time to detection of recurrence of 15.5 months. When determining the early prediction of recurrence within <6 months after SABR, physicians assessed the majority of images as benign injury/no recurrence, with a mean error of 35%, false positive rate (FPR) of 1%, and false negative rate (FNR) of 99%. At the same time point, a radiomic signature consisting of 5 image-appearance features demonstrated excellent discrimination, with an area under the receiver operating characteristic curve of 0.85, classification error of 24%, FPR of 24%, and FNR of 23%. Conclusions: These results suggest that radiomics can detect early changes associated with local recurrence that are not typically considered by physicians. This decision support system could potentially allow for early salvage therapy of

    Full Text Available Introduction: Intra-thoracic goiter refers to the extension of enlarged thyroid tissue into the thoracic inlet. This condition can produce symptoms of compression on adjacent organs and can sometimes be accompanied by malignant transformation. Therefore surgical treatment is almost always necessary. In order to remove the pathology with the fewest post-operative complications, selection of the appropriate surgical approach is essential. In this study we aimed to detect the criteria which help us select the best therapeutic approach.   Materials and Methods: In this retrospective study, 82 patients with intra-thoracic goiter were investigated. Their data were extracted from medical records and analyzed using SPSS software.   Results: Overall 82 patients, 18 (21% males and 64 (78% females with mean age of 56.38 years were studied. The most common clinical symptoms were mass (95% and dyspnea (73%. In most patients, the surgical approach was cervical (90.2%, while 9.8% of patients required an extra-cervical approach. Post-operation complications were observed in 17.1% of patients; the most common being transient recurrent laryngeal nerve paralysis (4.9%. Malignancy was reported in the histopathology of seven patients (8.5%. The most common malignant histopathology was papillary thyroid carcinoma (7.3%. Extension of the thyroid tissue below the uppermost level of the aortic arch was significantly correlated with the need for an extra-cervical approach to surgery (P

    2015-01-01

    Full Text Available This study evaluates the safety and effectiveness of computed tomography- (CT- assisted endoscopic surgery in the treatment of infectious spondylodiscitis of the thoracic and upper lumbar spine in immunocompromised patients. From October 2006 to March 2014, a total of 41 patients with infectious spondylodiscitis underwent percutaneous endoscopic surgery under local anesthesia, and 13 lesions from 13 patients on the thoracic or upper lumbar spine were selected for evaluation. A CT-guided catheter was placed before percutaneous endoscopic surgery as a guide to avoid injury to visceral organs, major vessels, and the spinal cord. All 13 patients had quick pain relief after endoscopic surgery without complications. The bacterial culture rate was 77%. Inflammatory parameters returned to normal after adequate antibiotic treatment. Postoperative radiographs showed no significant kyphotic deformity when compared with preoperative films. As of the last follow-up visit, no recurrent infections were noted. Traditional transthoracic or diaphragmatic surgery with or without posterior instrumentation is associated with high rates of morbidity and mortality, especially in elderly patients, patients with multiple comorbidities, or immunocompromised patients. Percutaneous endoscopic surgery assisted by a CT-guided catheter provides a safe and effective alternative treatment for infectious spondylodiscitis of the thoracic and upper lumbar spine.

    Full Text Available Objective: The aim of this study was to evaluate the trans-axillary surgical approach in patients with thoracic outlet syndrome. Methods: This retrospective study is comprised of data acquired from January 1998 until Oct 2008. Case histories of all the patients were reviewed from the Medical Records Department of Sher-i-Kashmir Institute. Relevant information and follow-up of the patients was carried out by examining the relevant clinical notes available by telephone interviews and personal contact whenever possible. All data was compiled and analyzed statistically. Results: There were a total of 139 patients. The female: male ratio was about 6:1. Pain was the most common presenting symptom followed by weakness and parasthesia. Nerve conduction velocity was abnormal in 111 patients. Twenty-eight patients had abnormal Doppler study of subclavian vessels. Preoperative symptoms persisted in 13 patients. Overall, 126 patients showed improvement in symptoms and no recurrence or persistence of symptoms on follow-up examination. Conclusion: Trans-axillary approach provides a good exposure and cosmesis in patients with thoracic outlet syndrome. It should be considered as the gold standard in the management of thoracic outlet syndrome.

    Pleural disease remains a commonly encountered clinical problem for both physician and surgeon. This study describes a new way to better diagnose and treat pleural diseases (hemothorax, empyema, and pleural effusion) using an electronic endoscope (gastroscope or bronchoscope). We conducted a retrospective study of the use of an electronic endoscope in the treatment and diagnosis of pleural diseases. From November 2006 to February 2008, a total of 17 patients (3 women, 14 men; mean age = 41.8 years; range = 18-62 years) underwent procedures for thoracic empyema (13 patients), traumatic clotted hemothorax (3 patients), and undiagnosed pleural effusion (1 patient). The electronic endoscope was inserted via the thoracic drainage tube for the treatment or diagnosis of pleural diseases after regular treatments, including thoracentesis, tube thoracostomy, and biopsy, failed. All patients were cured and discharged from hospital and were followed up for 6 months. The patients recovered well and there was no recurrence. The technique of inserting an electronic endoscope into the thoracic drainage tube for diagnosis and treatment of pleural diseases is simple, effective, minimally invasive, and cost-effective.

    Full Text Available Breast masses in children, though rare, present a difficult clinical challenge as they can represent a wide variety of entities from benign fibroadenomas to phyllodes tumors. Rapidly growing or recurrent masses can be particularly concerning to patients, families and physicians alike. Clinical examination and conventional imaging modalities are not efficacious in distinguishing between different tumor types and surgical excision is often recommended for both final diagnosis and for treatment of large or rapidly growing masses. While surgical excision can result in significant long-term deformity of the breast there are some surgical techniques that can be used to limit deformity and/or aid in future reconstruction. Here we present a case of recurrent giant juvenile fibroadenoma with a review of the clinical presentation, diagnostic tools and treatment options.

    We present our experience of total aortic arch replacement. Twenty-nine patients (21 males and 8 females; mean age 63.3 ± 13.3 years) with extended thoracic aortic aneurysms underwent graft replacement. The pathology of the diseased aorta was non-dissecting aneurysm in 11 patients, including one aortitis and aortic dissection in 18 patients (acute type A: one, chronic type A: 11, chronic type B: six). Five patients had Marfan syndrome. In their previous operation, two patients had undergone the Bentall procedure, three had endovascular stenting, one had aortic root replacement with valve sparing and 12 had hemi-arch replacement for acute type A dissection. Approaches to the aneurysm were as follows: posterolateral thoracotomy with rib-cross incision in 16, posterolateral thoracotomy extended to the retroperitoneal abdominal aorta in seven, mid-sternotomy and left pleurotomy in three, anterolateral thoracotomy with partial lower sternotomy in two and clam-shell incision in one patient. Extension of aortic replacement was performed from the aortic root to the descending aorta in 4, from the ascending aorta to the descending aorta in 17 and from the ascending to the abdominal aorta in eight patients. Arterial inflow for cardiopulmonary bypass consisted of the femoral artery in 15 patients, ascending aorta and femoral artery in seven, descending or abdominal aorta in five and ascending aorta in two. Venous drainage site was the femoral vein in 10, pulmonary artery in eight, right atrium in five, femoral artery with right atrium/pulmonary artery in four and pulmonary artery with right atrium in two patients. The operative mortality, 30-day mortality and hospital mortality was one (cardiac arrest due to aneurysm rupture), one (rupture of infected aneurysm) and one (brain contusion), respectively. Late mortality occurred in three patients due to pneumonia, ruptured residual aneurysm and intracranial bleeding. Actuarial survival at 5 years after the operations was 80.6

    Using five sham-operated and seven aortic coarctation-induced hypertensive New Zealand White rabbits intravenously injected with neutral small unilamellar vesicles loaded with [111In]nitrilotriacetic acid, we demonstrated in vivo that the normal aortic arterial wall participates in liposome uptake and that this uptake is increased in the hypertensive aortic wall by approximately threefold (p less than or equal to 0.0001). Among the three regions examined, aortic arch, thoracic aorta, and lower abdominal aorta, the difference in uptake between the normotensive and hypertensive arterial walls was significantly different, p less than or equal to 0.05, p less than or equal to 0.0001, and p less than 0.05, respectively. The uptake by the different regions of the hypertensive arterial wall is consistent with the pathological changes present in these areas. Furthermore, the extent of liposome uptake by the aortic wall is strongly correlated with the height of the blood pressure (r = 0.85, p = 0.001, n = 11). We conclude that neutral small unilamellar liposomes can be used to carry agents into the arterial wall in vivo in the study of hypertensive vascular disease and could be especially useful for the delivery of pharmacologically or biologically active agents that would otherwise be inactivated within the circulation or are impermeable to the arterial wall

  8. Multiplex Recurrence Networks

    The complex nature of a variety of phenomena in physical, biological, or earth sciences is driven by a large number of degrees of freedom which are strongly interconnected. Although the evolution of such systems is described by multivariate time series (MTS), so far research mostly focuses on analyzing these components one by one. Recurrence based analyses are powerful methods to understand the underlying dynamics of a dynamical system and have been used for many successful applications including examples from earth science, economics, or chemical reactions. The backbone of these techniques is creating the phase space of the system. However, increasing the dimension of a system requires increasing the length of the time series in order get significant and reliable results. This requirement is one of the challenges in many disciplines, in particular in palaeoclimate, thus, it is not easy to create a phase space from measured MTS due to the limited number of available obervations (samples). To overcome this problem, we suggest to create recurrence networks from each component of the system and combine them into a multiplex network structure, the multiplex recurrence network (MRN). We test the MRN by using prototypical mathematical models and demonstrate its use by studying high-dimensional palaeoclimate dynamics derived from pollen data from the Bear Lake (Utah, US). By using the MRN, we can distinguish typical climate transition events, e.g., such between Marine Isotope Stages.

    We report a case of recurrent post-partum pyoderma gangrenosum (PG) complicated by post-partum cardiomyopathy (PPCM). A 23-year-old woman presented with a previous medical history of aseptic abscess of the left breast in her fourth pregnancy, which developed after surgical drainage of an inflammatory ulceration treated by atraumatic topical care. During her fifth pregnancy, the patient presented a large and painful ulceration in relation to the scar of the Caesarean section, despite the introduction of broad-spectrum antibiotic therapy. Bacteriological samples were negative. Histological examination militated in favor of PG. One week after initiation of corticosteroid therapy, the patient suddenly showed signs of heart failure. Based on trans-thoracic echocardiography PPCM was diagnosed, and the outcome was fatal. This observation raises the question of the relationship between PG and pregnancy and describes the association of PG and PPCM. PG occurs rarely during pregnancy and it may be induced by the rise in G-CSF levels found in pregnant women. The association with PPCM seen in our patient could have been due to the development of an anti-angiogenic climate at the end of pregnancy, together with inflammatory myocardial aggression linked to the PG.

    Measurement of worker exposure to a thoracic health-related aerosol fraction is necessary in a number of occupational situations. This is the case of workplaces with atmospheres polluted by fibrous particles, such as cotton dust or asbestos, and by particles inducing irritation or bronchoconstriction such as acid mists or flour dust. Three personal and two static thoracic aerosol samplers were tested under laboratory conditions. Sampling efficiency with respect to particle aerodynamic diameter was measured in a horizontal low wind tunnel and in a vertical calm air chamber. Sampling performance was evaluated against conventional thoracic penetration. Three of the tested samplers performed well, when sampling the thoracic aerosol at nominal flow rate and two others performed well at optimized flow rate. The limit of flow rate optimization was found when using cyclone samplers. © The Author 2017. Published by Oxford University Press on behalf of the British Occupational Hygiene Society.

    Purpose: The main objective of this survey is to describe the current practice of thoracic anesthesia in the Middle Eastern (ME) region. Methods: A prospective online survey. An invitation to participate was e-mailed to all members of the ME thoracic-anaesthesia group. A total of 58 members participated in the survey from 19 institutions in the Middle East. Questions concerned ventilation strategies during one-lung ventilation (OLV), anesthesia regimen, mode of postoperative analgesia, use of lung isolation techniques, and use of i.v. fluids. Results: Volume-controlled ventilation was favored over pressure-controlled ventilation (62% vs 38% of respondents, Panesthesia practice. Failure to pass a DLT and difficult airway are the most commonly cited indications for BB use. Regarding postoperative analgesia, the majority 61.8% favor thoracic epidural analgesia over other techniques (P<0.05). Conclusions: Our survey provides a contemporary snapshot of the ME thoracic anesthetic practice. PMID:23162388

    Simple chest films of 106 cases of hemorrhagic fever with renal syndrome (HFRS) were reviewed retrospectively with clinical sequences. Renal type of Pulmonary edema (n=6), pulmonary congestion (n=3), pleural effusion (n=3), cardiomegaly (n=1) and subcutaneous emphysema (n=1) were the findings of thoracic manifestation of HFRS in order of frequency. Pulmonary edema and congestion were noted in oliguric and diuretic phases and noticeably seen when the oliguric phase was prolonged for more than 7 days (average oliguric phase, 3.3 days). Pleural effusion and cardiomegaly were also noted in oliguric and diuretic phases. Subcutaneous emphysema appeared in the diuretic phase. BUN/Cr level, EKG finding and platelet count didn't contribute to the thoracic findings. The type of pulmonary edema, in conjunction with the prolongation of the duration of oliguria and phase of revelation of thoracic findings suggest that fluid over load play a significant role in thoracic manifestation of HFRS.

    The vervet monkey (Chlorocebus sabaeus) is used commonly in cardiorespiratory biomedical research. This study was performed to establish reference values for thoracic structures and to describe the normal radiographic appearance of the vervet monkey thorax. Right lateral and dorsoventral thoracic radiographs of ten mature vervet monkeys were evaluated. Anatomic structures were characterized using descriptive statistics. Normal measurements of skeletal, pulmonary, mediastinal, and cardiovascular structures are reported herein. Several ratios were calculated to assess the cardiac silhouette, caudal vena cava, and pulmonary arteries and veins. Consistent measurements could be made on the majority of the thoracic structures evaluated. The aorta on lateral radiographs and the pulmonary veins on dorsoventral radiographs were obscured by a mild bronchointerstitial pattern and body conformation. Caudal vena cava-tapering was occasionally noted and attributed to general anesthesia. Species-specific thoracic radiographic reference values should prove useful in vervet monkey disease diagnosis and management. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Thoracic outlet syndrome is rare in children but may have serious consequences. Compression of the neurovascular structures at the thoracic outlet by anomalous soft tissues or cervical ribs may cause neurological deficits in the upper limb and venous or arterial insufficiency. The symptoms and signs of this condition are well documented, but we describe two patients with an atypical presentation. We review similar published cases where delay in diagnosis resulted in cerebrovascular catastrophe. Our patients presented with relatively nonspecific central nervous system symptoms and were found to have thoracic outlet compression. Both were treated by surgical decompression of the thoracic outlet, and the symptoms completely resolved with no long-lasting neurological consequences. We highlight the importance of these rare cases because of the risk of stroke and discuss the theory behind the pathological process. Copyright © 2014 Elsevier Inc. All rights reserved.

    Although the cumulative experience worldwide is still limited and evolving, Robotic Thoracic Surgery is an evolution over VATS. There is however a lot of concern among established high-volume VATS centers regarding the superiority of the robotic technique. We have over 7 years experience and believe that any new technology designed to make minimal invasive surgery easier and more comfortable for the surgeon is most likely to have better and safer outcomes in the long run. Our only concern is its cost effectiveness and we believe that if the cost factor is removed more and more surgeons will use the technology and it will increase the spectrum and the reach of minimally invasive thoracic surgery. This article reviews worldwide experience with robotic thoracic surgery and addresses the potential benefits and limitations of using the robotic platform for the performance of thoracic surgical procedures.

    Limb body wall complex (LBWC) is characterized by multiple severe congenital malformations including an abdominal and/or thoracic wall defect covered by amnion, a short or absent umbilical cord with the placenta almost attached to the anterior fetal wall, intestinal malrotation, scoliosis, and lower extremity anomalies. There is no consensus about the etiology of LBWC and many cases with abnormal facial cleft do not meet the requirements for the true complex. We describe a series of four patients with LBWC and other malformations in an attempt to explain their etiology. There are several reports of fetuses with LBWC and absent gallbladder and one of our patients also had polysplenia. Absent gallbladder and polysplenia are associated with laterality genes including HOX, bFGF, transforming growth factor beta/activins/BMP4, WNT 1-8, and SHH. We postulate that this severe malformation may be due to abnormal genes involved in laterality and caudal development.

    Full Text Available Ameloblastoma is locally aggressive benign odontogenic tumour with increased risk of recurrence rate. The choice of treatment depends on the histologic subtype. Radical therapy is the recommended modality for solid ameloblastomas. The possibilities of recurrence even after enbloc resection are still high. The author presents two case reports of recurrent ameloblastomas postradical resection. First case describes the recurrence of ameloblastoma in the bone graft which was used for reconstruction, and the second case depicts recurrence in the infratemporal fossa. Intraoperative radiography of the frozen section of the soft tissue margin plays an important role in the holistic management of these lesions.

    To evaluate prognostic factors and survival rates of the patients who received radiation therapy for locally recurrent uterine cervical cancer after curative surgery. Between October 1983 and July 1996, fifty three patients who received radiation therapy for locally recurrent cervical cancer after curative surgery at the Department of Therapeutic Radiology, Kangnam St. Mary's Hospital, The Catholic University of Korea were analysed retrospectively. Age at diagnosis ranged from 33 to 69 years (median 53 years). Pathological analysis showed that forty five (84.9%) patients had squamous cell carcinoma, seven (13.2%) patients had adenocarcinoma, and one (1.9%) patient had adenosquamous cell carcinoma. The interval between hysterectomy and tumor recurrence ranged from 2 months to 25 years (mean 34.4 months). The recurrent sites were vaginal stump in 41 patients (77.4%) and pelvic side wall in 12 patients (22.6%). Recurrent tumor size was divided into two groups: less than 3 cm in 43 patients (81.1%) and more than 3 cm in 10 patients (18.9%). External beam irradiation of whole pelvis was done first up to 46.8 Gy to 50.4 Gy in 5 weeks to 6 weeks, followed by either external beam boost to the recurrent site in 18 patients (34%) or intracavitary irradiation in 24 patients (45.3%). Total dose of radiation ranged from 46.8 Gy to 111 Gy (median 70.2 Gy). Follow up period ranged from 2 to 153 months with a median of 35 months. Overall response rate was 66% (35/53). Among them, six patients (17.1%) relapsed between 7 months and 116 months after radiation therapy (mean 47.7 months). Therefore overall recurrence rate was 45.3%. Overall five-year actuarial survival rate was 78.9% and distant failure rate was 10% (5/50). The significant prognostic factors affecting survival rate were interval between primary surgery and tumor recurrence (p=0.0055), recurrent tumor size (p=0.0039), and initial response to radiation therapy (p=0.0428). Complications were observed in 10 (20%) patients

    A prospective study. The aim of this study was to evaluate the outcomes and efficacy of using a 10Fr elastic tube with a regular negative pressure ball to treat the operative pleural tear in the complicated single-stage posterior approach thoracic spine surgeries. In some complicated single-stage posterior approach thoracic spine surgeries, such as total en bloc spondylectomy, pleural tear is quite inevitable. Traditional chest tube with a water-sealed bottle has many shortcomings, as pain, inconvenience, and other complications. In many thoracic surgeries, a smaller-caliber elastic tube has been used to avoid such complications and achieve quick recovery. However, there are concerns about the efficacy and safety of the smaller-caliber elastic tube. A prospective trial was performed in 72 patients between April 2008 and March 2012. Pleural tear occurred in 19 patients, among whom 10 patients were inserted a 10Fr elastic tube with a regular negative pressure ball (Group I), and nine were inserted a 28Fr chest tube with a water-sealed bottle (Group II). Comparative evaluation of the clinical and radiographic data was carried out. The basic condition of two groups did not differ significantly. The oxygen saturation monitor, hospital length of stay, average volume, and failure rate of drainage between two groups were not statistically significant. The difference of the visual analog score was significant (1.10 ± 0.35 vs. 3.89 ± 0.59, P tube with a regular negative pressure ball experienced less pain and a tendency of quicker recovery than those who received a 28Fr chest tube with a water-sealed bottle. The complication rate in Group I was not higher than Group II, indicating an equally good drainage efficacy. 2.

    Thoracic outlet syndrome is a disorder caused by thoracic outlet compression of the brachial plexus and/or the subclavian vessels. The characteristics of thoracic outlet syndrome are highly variable. Objective tests, such as electrodiagnostic studies, are often unreliable in characterizing thoracic outlet syndrome. The existence of thoracic outlet syndrome as a discrete entity is controversial. Surgeons who accept the existence of thoracic outlet syndrome acknowledge that diagnosis is clinical. The variability and complexity of thoracic outlet syndrome lends itself to mistakes in both diagnosis and surgical treatment.

  4. Radiation therapy of thoracic and abdominal tumors

    1995-01-01

    Until recently, radiotherapy of thoracic and abdominal tumors in animals has been limited. However, the availability of computerized tomography and other imaging techniques to aid in determining the extent of tumor, an increase in knowledge of dose tolerance of regional organs, the availability of isocentrically mounted megavoltage machines, and the willingness of patients to pursue more aggressive treatment is making radiation therapy of tumors in these regions far more common. Tumor remission has been reported after radiation therapy of thymomas. Radiation therapy has been used to treat mediastinal lymphoma refractory to chemotherapy, and may be beneficial as part of the initial treatment regimen for this disease. Chemodectomas are responsive to radiation therapy in human patients, and favorable response has also been reported in dogs. Although primary lung tumors in dogs are rare, in some cases radiation therapy could be a useful primary or adjunctive therapy. Lung is the dose-limiting organ in the thorax. Bladder and urethral tumors in dogs have been treated using intraoperative and external-beam radiation therapy combined with chemotherapy. These tumors are difficult to control locally with surgery alone, although the optimal method of combining treatment modalities has not been established. Local control of malignant perianal tumors is also difficult to achieve with surgery alone, and radiation therapy should be used. Intraoperative radiation therapy combined with external-beam radiation therapy has been used for the management of metastatic carcinoma to the sublumbar lymph nodes. Tolerance of retroperitoneal tissues may be decreased by disease or surgical manipulation

    Background: a chylothorax is a rare complication of mostly advanced malignant lymphomas. A case of a refractory chylothorax unresponsive to chemotherapy and successfully treated with radiotherapy is reported. Case report: a 45-year-old woman with recurrent stage IV low-grade follicular non-Hodgkin's lymphoma and a progressive chylothorax is described. The CT scans showed bulky lymphadenopathy at the thoracic trunk but no detectable enlargement of mediastinal lymph nodes. After ineffective pretreatment including chemotherapy and chest drainage, fractionated radiotherapy to the celiac trunk (20.4 Gy) and the thoracic duct (15 Gy) was performed. Result: already after 7.5 Gy a rapid decline of chylothorax was noted and the chest drain could be removed. A complete remission of the chylothorax could be achieved after 20.4 Gy. During a follow-up of 16 months no recurrence of chylothorax occurred. CT scans showed nearly complete remission of the lymphadenopathy of the celiac trunk 12 months after radiotherapy. Conclusion: radiotherapy with limited total doses is an effective treatment option for lymphoma-associated chylothorax and should always be taken into consideration, especially in cases unresponsive to chemotherapy.

    Prognosis of locally advanced esophageal cancer is poor. The greatest prognostic factor of locally advanced esophageal cancer is a local control. We experienced a case of T4 locally advanced thoracic esophageal cancer who was successfully resected without any combined resection after multimodality therapy. A male in 75-year-old. was diagnosed with type 3 locally advanced upper thoracic esophageal cancer whose metastatic right recurrent laryngeal lymph node invaded into the trachea. Definitive chemoradiation therapy(CRT)was performed, leading to a significant shrinkage of the main tumor, but T4 lesion remained. Next, adding DCF therapy(docetaxel, CDDP and 5-FU), a relief of T4 was finally obtained. Then, salvage surgery with subtotalesophagectomy and retrosternalesophagealreconstruction with gastric tube was performed, resulting in R0 resection without any combined resection. The postoperative course was uneventful, and the patient has been alive without recurrence for 1 year after surgery. In locally advanced cancer, focusing on T4 downstaging, it is significantly important in terms of safety, curativity and organ preservation to perform surgery after a sure sign of T4 relief by multimodality therapy.

    This paper summarizes the treatment of locally advanced breast cancer, inflammatory breast cancer, and locally recurrent breast cancer. A multidisciplinary approach considering subclinical distant metastases is needed to treat these types of breast cancer. Subclinical distant metastasis is observed in about 80% of case of locally advanced cancer, and treatment of subclinical distant metastases, e.g., by endocrinotherapy and chemotherapy, is therefore essential to improving the prognosis. The standard therapy for unresectable locally advanced breast cancer consists of induction chemotherapy with anthracyclines and local treatment with mastectomy or irradiation. Previous reports have stated that induction chemotherapy was effective in 60-80% of the primary lesions or lymph node metastasis, and the CR rates were in the 10-20% range. Combination therapy with induction chemotherapy clearly improved the outcome over local treatment alone. The usual irradiation dose is 50 to 60 Gy/5 to 7 weeks to the whole breast or the thoracic wall. Boost irradiation at a dose of 10 to 25 Gy is performed in unresectable cases. The boost irradiation dose to the lymph node area is usually 45 to 50 Gy/5 to 6 weeks in cases without gross lesions and 10 to 15 Gy in cases with gross lesions. Combination therapy consisting of conservative pectoral mastectomy and postoperative adjuvant chemo- endocrino-therapy (i.e., adjuvant therapy) has become the standard regimen for treating resectable locally advanced breast cancer, because it significantly improves the recurrence rate and survival rate compared to local treatment alone. Some clinical have studies indicated that neoadjuvant therapy (i.e., induction chemotherapy + surgery/radiation therapy) is comparable or superior to adjuvant therapy in terms of improving the prognosis. However, the efficacy and most appropriate method of breast-conserving therapy after induction chemotherapy are still unclear. More clinical trials are needed. It has been

    The use of thoracic ultrasound outside the radiology department and in everyday clinical practice is becoming increasingly common, having been incorporated into standards of care for many specialties. For the majority of practitioners, their experience of, and exposure to, thoracic ultrasound will be in its use as an adjunct to pleural and thoracic interventions, owing to the widely recognised benefits for patient safety and risk reduction. However, as clinicians become increasingly familiar with the capabilities of thoracic ultrasound, new directions for its use are being sought which might enhance practice and patient care. This article reviews the ways in which the advent of thoracic ultrasound is changing the approach to the investigation and treatment of respiratory disease from an interventional perspective. This will include the impact of thoracic ultrasound on areas including patient safety, diagnostic and therapeutic procedures, and outcome prediction; and will also consider potential future research and clinical directions.

    The aim of this study was to assess the relationship between radiation therapy (RT) and treatment-related mortality in patients receiving high-dose chemotherapy (HDCT) and autologous bone marrow transplantation (ABMT) for recurrent/refractory Hodgkin's disease (HD). Between December 1986 and December 1992, 59 patients previously treated at the Princess Margaret Hospital underwent HDCT (etoposide 60 mg/kg, melphalan 160 mg/m{sup 2}) and ABMT, performed for refractory (13 patients) or relapsed (46 patients) HD. RT was incorporated in the salvage treatment with the intent to achieve complete control of disease prior to ABMT. RT was given before ABMT in 33 patients, and after ABMT in 4 patients. Treatment-related (TR) mortality was defined as any death occurring within 100 days of ABMT. Autopsies were performed for all patients with TR deaths. With a median follow-up of 4.6 years (range 1.2-7.4 years), the actuarial overall survival was 41%{+-}14% at 5 years. We observed 37 deaths, and 10 of these were TR deaths. Among the 24 patients who received thoracic RT before ABMT, there were 8 TR deaths, 3 of these solely attributable to radiation pneumonitis. The remaining 5 TR deaths all had respiratory failure with complicating sepsis as a major medical problem. The interval from RT to ABMT was shorter for 8 patients dying of TR death (mean 37 days; range 0-103 days), than for the 16 survivors (mean 105 days; range 0-263 days) (P=0.026). Among 9 patients with ABMT within 50 days of thoracic RT, 6 had TR death. In contrast, among the 35 patients without thoracic RT (26 no RT, 9 non-thoracic RT), there were only 2 TR deaths. The 4 patients treated with mantle RT post-ABMT had no serious pulmonary complications. The use of thoracic RT before HDCT and ABMT was associated with a high post-transplant mortality rate. It was most evident in patients who received thoracic RT within 50 days prior to ABMT, or when the target volume included large volume of lung. We recommend that

    To utilize 3-D modeling techniques to better characterize geometric deformations of the supra-aortic arch branch vessels and descending thoracic aorta after thoracic endovascular aortic repair. Eighteen patients underwent endovascular repair of either type B aortic dissection (n = 10) or thoracic aortic aneurysm (n = 8). Computed tomography angiography was obtained pre- and postprocedure, and 3-D geometric models of the aorta and supra-aortic branch vessels were constructed. Branch angle of the supra-aortic branch vessels and curvature metrics of the ascending aorta, aortic arch, and stented thoracic aortic lumen were calculated both at pre- and postintervention. The left common carotid artery branch angle was lower than the left subclavian artery angles preintervention ( P Supra-aortic branch vessel angulation remains relatively static when proximal landing zones are distal to the left common carotid artery.

    We report a successful resection of an osteosarcoma in the chest wall developed 25 years after irradiation. A 74-year-old woman was admitted to our hospital for her swelling in the left chest wall at August 24, 1995. At 49-year-old, she had undergone an operation and postoperative irradiation for left breast cancer. A computed tomography demonstrated a mass in the left chest wall that destructed the first rib, extending into the pleural space and invaded into the left common carotid and subclavian arteries. We planned a radical resection of the mass after repeated CT scannings, since it was histopathologically diagnosed as a chondrosarcoma and showed a rapid growth. The tumor was completely removed with radical transmediastinal forequarter amputation of the partial chest wall and total left upper extremity. The left common carotid artery was partially replaced with 6 mm EPTFE vascular prosthesis. The chest wall was reconstructed with Marlex-mesh prosthesis and a myocutaneous flap. She was discharged uneventfully and has not shown any evidence of recurrence. (author)

    The thoracic outlet syndromes (TOSs) are a group of etiologically and clinically distinct disorders with 1 feature in common: compression of 1 or more neurovascular elements as they traverse the thoracic outlet. The medical literature reflects 5 TOSs: arterial; venous; traumatic neurovascular; true neurogenic; and disputed. Of these, the first 4 demonstrate all of the features expected of a syndrome, whereas disputed TOS does not, causing many experts to doubt its existence altogether. Thus, some categorize disputed TOSs as cervicoscapular pain syndrome rather than as a type of TOS. To better understand these disorders, their distinctions, and the reasoning underlying the categorical change of disputed TOS from a form of TOS to a cervicoscapular pain syndrome, a thorough understanding of the pertinent anatomy, pathology, pathophysiology, and electrodiagnostic manifestations of these pathophysiologies is required. This review of the TOSs is provided in 2 parts. In part 1 we covered general information pertinent to all 5 TOSs and reviewed true neurogenic TOS in detail. In part 2, we review the arterial, venous, traumatic neurovascular, and disputed forms of TOS.

    Neuroradiological techniques were used to elucidate pathophysiology of recurrent cerebral thrombosis. Twenty-two patients with cerebral thrombosis who suffered a second attack under stable conditions more than 22 days after the initial stroke were studied. Hypertension, diabetes mellitus, and hypercholesterolemia were also seen in 20, 8, and 12 patients, respectively. The patients were divided into three groups according to their symptoms: (I) symptoms differed between the first and second strokes (n=12); (II) initial symptoms were suddenly deteriorated (n=6); and (III) symptoms occurring in groups I and II were seen (n=4). In group I, contralateral hemiparesis or suprabulbar palsy was often associated with the initial hemiparesis. The time of recurrent stroke varied from 4 months to 9 years. CT and MRI showed not only lacunae in both hemispheres, but also deep white-matter ischemia of the centrum semi-ovale. In group II, hemiparesis or visual field defect was deteriorated early after the initial stroke. In addition, neuroimaging revealed that infarction in the posterior cerebral artery was progressed on the contralateral side, or that white matter lesion in the middle artery was enlarged in spite of small lesion in the left cerebral hemisphere. All patients in group III had deterioration of right hemiparesis associated with aphasia. CT, MRI, SPECT, and angiography indicated deep white-matter ischemia caused by main trunk lesions in the left hemisphere. Group III seemed to be equivalent to group II, except for laterality of the lesion. Neuroradiological assessment of the initial stroke may help to predict the mode of recurrence, although pathophysiology of cerebral thrombosis is complicated and varies from patient to patient.

    Miller Fisher syndrome (MFS) is a variant of Guillan Barre syndrome characterized by the triad of ophthalmoplegia, ataxia and areflexia. Recurrences are exceptional with Miller Fisher syndrome. We are reporting a case with two episodes of MFS within two years. Initially he presented with partial ophthalmoplegia, ataxia. Second episode was characterized by full-blown presentation characterized by ataxia, areflexia and ophthalmoplegia. CSF analysis was typical during both episodes. Nerve conduction velocity study was fairly within normal limits. MRI of brain was within normal limits. He responded to symptomatic measures initially, then to steroids in the second episode. We are reporting the case due to its rarity.

    Primary cardiac tumors are rare. Mixomas are the most common among them; 75% are located in the left atrium, 20% in the right atrium, and the rest in the ventricles. The seldom appear in atrio-ventricular valves. Recidivant mixoma are also rare, appearing in 1-5% of all patients that have undergone surgical treatment of a mixoma. In this paper we present our experience with a female patient, who 8 years after having been operated of a left atrial mixoma, began with symptoms of mild heart failure. Transthoracic echocardiography revealed recurrence of the tumor, and was therefore subjected to a second open-heart surgery from which she recovered without complications.

    Full Text Available Antiphospholipid antibodies (APA are associated with thrombosis, thrombocytopenia and fetal loss but they occur in a variety of diseases. Despite many efforts, a correlation between the specificity of particular subgroups of APA and particular clinical situations remains to be established. The antigens at the origin of APA remain to be identified. We discuss here the possible links between cell apoptosis or necrosis, leading to plasma membrane alterations, and the occurrence of APA in response to sustained stimulation. The pathogenic potential of APA is also considered with respect to recurrent pregnancy loss.

    Purpose: The purpose of this study was to characterize the heartbeat-related displacement of the thoracic aorta in patients with chronic aortic dissection type B (CADB). Materials and methods: Electrocardiogram-gated computed tomography angiography was performed during inspiratory breath-hold in 11 patients with CADB: Collimation 16 mm x 1 mm, pitch 0.2, slice thickness 1 mm, reconstruction increment 0.8 mm. Multiplanar reformations were taken for 20 equidistant time instances through both ascending (AAo) and descending aorta (true lumen, DAoT; false lumen, DAoF) and the vertex of the aortic arch (VA). In-plane vessel displacement was determined by region of interest analysis. Results: Mean displacement was 5.2 {+-} 1.7 mm (AAo), 1.6 {+-} 1.0 mm (VA), 0.9 {+-} 0.4 mm (DAoT), and 1.1 {+-} 0.4 mm (DAoF). This indicated a significant reduction of displacement from AAo to VA and DAoT (p < 0.05). The direction of displacement was anterior for AAo and cranial for VA. Conclusion: In CADB, the thoracic aorta undergoes a heartbeat-related displacement that exhibits an unbalanced distribution of magnitude and direction along the thoracic vessel course. Since consecutive traction forces on the aortic wall have to be assumed, these observations may have implications on pathogenesis of and treatment strategies for CADB.

    This study describes the feasibility of Contrast Enhanced Ultrasonography (CEUS) in the diagnostic work-up of non-cardiac thoracic disorders of small animals. The second aim is to assess the usefulness of CEUS as a direct guide for sample procedures. Forty animals, 28 dogs and 12 cats, were included in the study. Thoracic disorders included 23 pulmonary lesions [primary carcinoma (14), lymphoma (1), sarcoma (1), histiocytic sarcoma (1), abscess (1) and pneumonia (5)] and 17 mediastinal lesions [lymphoma (8), thymoma (3), mesothelioma (1), melanoma (1), carcinomatous lymphadenopathy (1), mixsosarcoma (1), lipoma (1), and abscess (1)]. The majority of neoplastic pulmonary lesions showed an inhomogeneous distribution of contrast medium, whereas inflammatory lesions had a homogenous distribution with typical pulmonary vessels ramification. The majority of mediastinal malignant lesions showed an inhomogeneous distribution pattern. The lung and mediastinal abscesses had peripheral enhancement of the wall with an avascular center. All cytological and biopsy samples obtained after CEUS were diagnostic. Quantitative analysis, performed in 19/23 pulmonary lesions, showed a statistically significant difference (P pulmonary lesions. CEUS may be a useful tool for the evaluation of non-cardiac thoracic lesions. The contrast medium allows for the precise definition of lesion edges, the presence of necrotic areas, and the distribution of pulmonary vessels. Based on our preliminary results, the use of ultrasonographic contrast medium can be recommended for improving the diagnostic usefulness of cytology and biopsy sampling, because CEUS may help to define necrotic areas from viable tissue.

    The blood flow patterns of chronic thoracic aortic dissection are complicated, and their clinical significance remains unknown. We evaluated the technical and clinical potentials of time-resolved 3-dimensional (3D) magnetic resonance (MR) velocity mapping for assessing these patterns. We used data collected from time-resolved 3D phase-contrast MR imaging of 16 patients with chronic thoracic aortic dissection to generate time-resolved 3D MR velocity mapping that included 3D streamline and path line. We investigated blood flow patterns of this disease in the mapping and compared them with the morphological changes of the patent false lumen. Time-resolved 3D MR velocity mapping visualized rapid flow at the entry and in the true lumen immediately distal to the entry. We observed slower helical or laminar flow in the patent false lumen. In patients with disease progression, slower helical flow following rapid entry jet collided with the outer wall of the false lumen and was also observed in a growing ulcer-like projection. We showed the potential of time-resolved 3D MR velocity mapping for visualizing pathologic flow patterns related to chronic thoracic aortic dissection. (author)

    We discuss MRI findings in patients with thoracic outlet syndrome (TOS). A total of 100 neurovascular bundles were evaluated in the interscalene triangle (IS), costoclavicular (CC), and retropectoralis minor (RPM) spaces. To exclude neurogenic abnormality, MRIs of the cervical spine and brachial plexus (BPL) were obtained in neutral. To exclude compression on neurovascular bundles, sagittal T1W images were obtained vertical to the longitudinal axis of BPL from spinal cord to the medial part of the humerus, in abduction and neutral. To exclude vascular TOS, MR angiography (MRA) and venography (MRV) of the subclavian artery (SA) and vein (SV) in abduction were obtained. If there is compression on the vessels, MRA and MRV of the subclavian vessels were repeated in neutral. Seventy-one neurovascular bundles were found to be abnormal: 16 arterial-venous-neurogenic, 20 neurogenic, 1 arterial, 15 venous, 8 arterial-venous, 3 arterial-neurogenic, and 8 venous-neurogenic TOS. Overall, neurogenic TOS was noted in 69%, venous TOS in 66%, and arterial TOS in 39%. The neurovascular bundle was most commonly compressed in the CC, mostly secondary to position, and very rarely compressed in the RPM. The cause of TOS was congenital bone variations in 36%, congenital fibromuscular anomalies in 11%, and position in 53%. In 5%, there was unilateral brachial plexitis in addition to compression of the neurovascular bundle. Severe cervical spondylosis was noted in 14%, contributing to TOS symptoms. For evaluation of patients with TOS, visualization of the brachial plexus and cervical spine and dynamic evaluation of neurovascular bundles in the cervicothoracobrachial region are mandatory.

    Three-dimensional conformal radiotherapy (3D CRT) is adversely affected by setup error and organ motion. In thoracic 3D CRT, breathing accounts for most of intra-fraction movements, thus impairing treatment quality. Breath control clearly exhibits dosimetric improvement compared to free breathing, leading to various techniques for gated treatments. We review benefits of different breath control methods -i.e. breath-holding or beam gating, with spirometric, isometric or X-ray respiration sensor- and argument the choice of expiration versus inspiration, with consideration to dosimetric concerns. All steps of 3D-CRT can be improved with breath control. Contouring of organs at risk (OAR) and target are easier and more accurate on breath controlled CT-scans. Inter- and intra-fraction target immobilisation allows smaller margins with better coverage. Lung outcome predictors (NTCP, Mean Dose, LV20, LV30) are improved with breath-control. In addition, inspiration breath control facilitates beam arrangement since it widens the distance between OAR and target, and leaves less lung normal tissue within the high dose region. Last, lung density, as of CT scan, is more accurate, improving dosimetry. Our institutions choice is to use spirometry driven, patient controlled high-inspiration breath-hold; this technique gives excellent immobilization results, with high reproducibility, yet it is easy to implement and costs little extra treatment time. Breath control, whatever technique is employed, proves superior to free breathing treatment when using 3D-CRT. Breath control should then be used whenever possible, and is probably mandatory for IMRT. (authors)

    Purpose The goal of this study was to determine the feasibility of electromagnetic tracking as a method to augment conventional imaging guidance for the safe delivery, precise positioning, and accurate deployment of thoracic aortic endografts. Materials & Methods Custom guidewires were fabricated and the delivery catheters for thoracic aortic endoprostheses (Gore TAG endoprostheses, W.L. Gore & Assoc. Inc., Flagstaff AZ) were retrofitted with integrated electromagnetic coil sensors enabling realtime endovascular tracking. Pre-procedure thoracic CTA were obtained after placement of fiducial skin patches on the chest wall of three anesthetized swine, enabling automatic registration. The stent graft deployment location target near the subclavian artery was selected on the pre-procedure CTA. Two steps were analyzed: advancing a tracked glidewire to the aortic arch, and positioning the tracked stent graft assembly using electromagnetic guidance alone. Multiple CT scans were performed to evaluate the accuracy of the electromagnetic tracking system by measuring the target registration error which compared the actual position of the tracked devices to the displayed “virtual” electromagnetic-tracked position. Post-deployment CTA and necropsy confirmed stent graft position and subclavian artery patency. Results A stent graft was successfully delivered and deployed in each of the three animals using real-time electromagnetic tracking alone. The mean of the fiducial registration error of the auto-registration was 1.5 mm. Sixteen comparative scans were obtained to determine the target registration error, which was 4.3mm ± 0.97 mm (Range: 3.0 to 6.0mm) for the glidewire sensor coil. The target registration error for the stent graft delivery catheter sensor coil was 2.6 mm ± 0.7 mm (Range: 1.9 to 3.8 mm). The deployment error for the stent graft defined as deployment deviation from target was 2.6mm ± 3.0 mm. Conclusion Delivery and deployment of customized thoracic stent

Further investigations confirmed the diagnosis of coeliac disease. The combination of small bowel intussusception, coeliac disease and cholelithiasis is unique and has not been reported in the literature.

  11. Liquid Wall Chambers

    2011-02-24

    The key feature of liquid wall chambers is the use of a renewable liquid layer to protect chamber structures from target emissions. Two primary options have been proposed and studied: wetted wall chambers and thick liquid wall (TLW) chambers. With wetted wall designs, a thin layer of liquid shields the structural first wall from short ranged target emissions (x-rays, ions and debris) but not neutrons. Various schemes have been proposed to establish and renew the liquid layer between shots including flow-guiding porous fabrics (e.g., Osiris, HIBALL), porous rigid structures (Prometheus) and thin film flows (KOYO). The thin liquid layer can be the tritium breeding material (e.g., flibe, PbLi, or Li) or another liquid metal such as Pb. TLWs use liquid jets injected by stationary or oscillating nozzles to form a neutronically thick layer (typically with an effective thickness of {approx}50 cm) of liquid between the target and first structural wall. In addition to absorbing short ranged emissions, the thick liquid layer degrades the neutron flux and energy reaching the first wall, typically by {approx}10 x x, so that steel walls can survive for the life of the plant ({approx}30-60 yrs). The thick liquid serves as the primary coolant and tritium breeding material (most recent designs use flibe, but the earliest concepts used Li). In essence, the TLW places the fusion blanket inside the first wall instead of behind the first wall.

    Thirty patients treated with surgical resection and brachytherapy for chest wall sarcoma at Memorial Sloan-Kettering Cancer Center from 1980 through 1987 were reviewed. Patients selected to receive adjuvant irradiation were those for whom there was doubt as to the completeness of surgical resection. Overall 5-year survival and locoregional control after brachytherapy were 65% and 54%, respectively. Locoregional control was similar for tumors treated at initial diagnosis (12 patients), at the time of recurrence (13 patients), or for tumors that were metastatic to the chest wall (five patients). Six patients with tumors larger than 10 cm in maximum dimension had a locoregional recurrence rate of 69% versus a recurrence rate of 39% for 18 patients with smaller tumors (p = 0.27). Fifty-four percent of high-grade tumors recurred locoregionally versus 28% of low-grade tumors (p = 0.37). Bone invasion or the presence of positive resection margins was not clearly associated with a higher locoregional failure rate. Only one patient (1/28; 7%) was known to have had recurrence within the irradiated area. Eight patients (8/28; 37%) had recurrence adjacent to the implanted area, and the precise failure site could not be determined for the remaining two patients. Because of the relatively high risk of regional versus in-field recurrence, patients with chest wall sarcoma who receive adjuvant treatment should be treated primarily with external-beam irradiation to allow more generous coverage of the tumor bed. Brachytherapy could be used as a tumor bed 'boost' treatment. In patients undergoing resection of recurrent tumor in a previously irradiated site, adjuvant brachytherapy, without external-beam irradiation, should be considered to reduce the risk of extensive soft tissue necrosis

    Full Text Available Objective: Thoracic outlet syndrome is a complex disorder caused by neurovascular irritation in the region of the thoracic outlet. The syndrome have been said to be mainly due to anomalous structures in the thoracic outlet, treatment for thoracic outlet syndrome varies among different institutions, and there has not been any standard program. In general conservative and surgical treatment can be do if necessary. Materials & Methods: The rehabilitation program consists of exercise and physiotherapy and brace designed to hold the posture in which thoracic outlet is enlarged. Exercise program was designed simple enough to be performed in the daily living or during work after minimal training and isometric exercises of Serratus anterior, Levator Scapulae and Erector Spinae muscles to be performed in one posture: flexion and elevation of scapular girdle and correction position of upper-thoracic spine. During 7 years, 131 cases of (T.O.S. were evaluated that 26 cases (20% have operated and 84 cases (64% have treated with conservative treatment and 21 cases (16% have been candidate for surgery but they didn't accepted. Results: All of the cases have treated with conservative treatment for four months. 84 cases responded well and no further treatment was needed. 47 cases were not satisfied with. The outcome of their treatment, that 26 cases have operated and 21 cases have not accepted the operation and continued the conservative treatment, they have had pain and slightly disability. 23 cases of operated group responded well and they have resumed to work, one case has had neuropraxia for about one year. Conclusion: Most cases of thoracic outlet syndrome (T.O.S. can be treated conservatively. Surgically treatment is indicated only in cases severe enough to make them disable to work. It is better all the patients undergo conservative treatment for at least four months then will decided for surgical treatment.

    The hybrid treatment of transverse aortic arch pathologies with supraaortic debranching and endovascular repair is associated with significant morbidity and death and lacks long-term follow-up. The traditional two-stage open surgical approach to extensive arch and descending thoracic aneurysms carries a significant interval mortality rate. We report the results of a single-stage technique of total arch and descending thoracic aortic replacement by a left thoracotomy. From January 1995 to February 2011, 426 patients underwent thoracic or thoracoabdominal aneurysm repair, of which a highly selected group of 27 patients underwent total arch replacement with descending thoracic or thoracoabdominal aortic replacement. All procedures were performed with hypothermic circulatory arrest and selective antegrade cerebral perfusion. Two patients required transverse division of the sternum. Two patients had emergency or urgent operations. Five patients had concomitant coronary artery bypass, and 1 had concomitant mitral valve replacement. There were no hospital deaths, no cerebrovascular accidents, and one instance of transient spinal cord ischemia. Three patients had acute renal failure not requiring hemodialysis. Intubation in 5 patients exceeded 48 hours, and 1 patient needed tracheostomy. Two patients required reexploration for postoperative bleeding. Survival at 1, 3, and 5 years was 95%, 78%, and 73%, respectively. Replacement of the total arch and descending thoracic aorta by a left thoracotomy provides excellent short-term and long-term results for the treatment of extensive arch and thoracic aortic pathology, without the need for a second-stage operation. Other cardiac pathologies, such as left-sided coronary disease and mitral valve disease, can be addressed concurrently. Copyright © 2012 The Society of Thoracic Surgeons. Published by Elsevier Inc.

    The red panda ( Ailurus fulgens ) is classified as an endangered species by the International Union for Conservation of Nature and Natural Resources. The natural distribution of the red panda is in the Himalayas and southern China. Thoracic diseases such as dirofilariasis, hypertrophic cardiomyopathy, tracheal obstruction, lung worm infestation, and pneumonia have been reported in the red panda. The aim of this study was to describe the normal radiographic thoracic anatomy of captive red pandas as a species-specific reference for routine health examinations and clinical cases. Right lateral (RL) and dorsoventral (DV) inspiratory phase views of the thorax were obtained in 11 adult captive red pandas. Measurements were made and ratios calculated to establish reference ranges for the mean vertebral heart score on the RL (8.34 ± 0.25) and DV (8.78 ± 0.34) views and the mean ratios of the caudal vena cava diameter to the vertebral body length above tracheal bifurcation (0.67 ± 0.05) and tracheal diameter to the width of the third rib (2.75 ± 0.24). The majority of animals (10/11) had 14 thoracic vertebrae, except for one animal that had 15 thoracic vertebrae. Rudimentary clavicles were seen in 3/11 animals. The ovoid, oblique cardiac silhouette was more horizontally positioned and elongated in older animals. A redundant aortic arch was seen in the oldest animal. The trachea was seen with mineralized cartilage rings in all animals. The carina was clearly seen in the majority of animals (10/11). Variations exist in the normal radiographic thoracic anatomy of different species. Knowledge of the normal radiographic thoracic anatomy of the red panda should prove useful for routine health examinations and in the diagnosis of thoracic diseases.

    Objective Malignant chest wall tumors are rare neoplasms. Resection with wide-free margins is an important prognostic factor, and massive chest wall resection and reconstruction are often necessary. A recent case series of 20 consecutive patients is reported in order to find any possible correlation between tumor histology, extent of resection, type of reconstruction, and adjuvant treatment with short- and long-term outcomes. Methods Twenty patients were submitted to chest wall resection and reconstruction for malignant chest wall neoplasms between 2006 and 2014. The mean age (ten males) was 59±4 years. The size and histology of the tumor, the technique of reconstruction, and the short- and long-term follow-up records were noted. Results The median maximum diameter of tumors was 10 cm (5.4–32 cm). Subtotal sternal resection was performed in nine cases, and the resection of multiple ribs was performed in eleven cases. The median area of chest wall defect was 108 cm2 (60–340 cm2). Histology revealed soft tissue, bone, and cartilage sarcomas in 16 cases (80%), most of them chondrosarcomas. The rest of the tumors was metastatic tumors in two cases and localized malignant pleural mesothelioma and non-Hodgkin lymphoma in one case. The chest wall defect was reconstructed by using the “sandwich technique” (propylene mesh/methyl methacrylate/propylene mesh) in nine cases of large anterior defects or by using a 2 mm polytetrafluoroethylene (e-PTFE) mesh in nine cases of lateral or posterior defects. Support from a plastic surgeon was necessary to cover the full-thickness chest wall defects in seven cases. Adjuvant oncologic treatment was administered in 13 patients. Local recurrences were observed in five cases where surgical reintervention was finally necessary in two cases. Recurrences were associated with larger tumors, histology of malignant fibrous histiocytoma, and initial incomplete resection or misdiagnosis made by nonthoracic surgeons. Three patients died

    Objective: To evaluates a semi-automated method for Thoracic Aortic Aneurysm (TAA) measurement using ECG-gated Dual Source CT Angiogram (DSCTA). Methods: This retrospective HIPAA compliant study was approved by our IRB. Transaxial maximum diameters of outer wall to outer wall were studied in fifty patients at seven anatomic locations of the thoracic aorta: annulus, sinus, sinotubular junction (STJ), mid ascending aorta (MAA) at the level of right pulmonary artery, proximal aortic arch (PROX) immediately proximal to innominate artery, distal aortic arch (DIST) immediately distal to left subclavian artery, and descending aorta (DESC) at the level of diaphragm. Measurements were performed using a manual method and semi-automated software. All readers repeated their measurements. Inter-method, intra-observer and inter-observer agreements were evaluated according to intraclass correlation coefficient (ICC) and Bland–Altman plot. The number of cases with manual contouring or center line adjustment for the semi-automated method and also the post-processing time for each method were recorded. Results: The mean difference between semi-automated and manual methods was less than 1.3 mm at all seven points. Strong inter-method, inter-observer and intra-observer agreement was recorded at all levels (ICC ≥ 0.9). The maximum rate of manual adjustment of center line and contour was at the level of annulus. The average time for manual post-processing of the aorta was 19 ± 0.3 min, while it took 8.26 ± 2.1 min to do the measurements with the semi-automated tool (Vitrea version 6.0.0.1 software). The center line was edited manually at all levels, with most corrections at the level of annulus (60%), while the contour was adjusted at all levels with highest and lowest number of corrections at the levels of annulus and DESC (75% and 0.07% of the cases), respectively. Conclusion: Compared to the commonly used manual method, semi-automated measurement of vessel dimensions is

    A 32 year old woman presented with acute onset of abdominal pain and fever. An urgent computerised tomography (CT) of the whole abdomen showed dilated loop at the terminal ileum in the right lower abdomen with thickening of the wall and oedema. The CT was suggestive of distal small bowel obstruction at the ileum with surrounding wall oedema. Multiple biopsies taken from the terminal ileum and colon on colonoscopy were all unremarkable. She represented one-year later with a recurrence of intestinal obstruction. CT enteroclysis showed collapse at the distal 3 cm segment of the terminal ileum. There was no associated wall thickening, active inflammatory changes or ileitis. This was suspicious of post-inflammatory change or fibrosis. She was subsequently found to have selective IgA deficiency with recurrent infection in the terminal ileum resulting in intestinal obstruction. In conclusion, selective IgA deficiency should be considered in patients with recurrent intestinal obstruction without anatomical obstructions.

    Recurrence plots exhibit line structures which represent typical behaviour of the investigated system. The local slope of these line structures is connected with a specific transformation of the time scales of different segments of the phase-space trajectory. This provides us a better understanding of the structures occurring in recurrence plots. The relationship between the time-scales and line structures are of practical importance in cross recurrence plots. Using this relationship within cross recurrence plots, the time-scales of differently sampled or time-transformed measurements can be adjusted. An application to geophysical measurements illustrates the capability of this method for the adjustment of time-scales in different measurements

    Venous thrombosis, including deep vein thrombosis and pulmonary embolism, is a common disease that frequently recurs. Recurrence can be prevented by anticoagulants, but this comes at the risk of bleeding. Therefore, assessment of the risk of recurrence is important to balance the risks and benefits of anticoagulant treatment. This review briefly outlines what is currently known about the epidemiology of recurrent venous thrombosis, and focuses in more detail on potential new risk factors for venous recurrence. The general implications of these findings in patient management are discussed. PMID:22183247

    Full Text Available In the last years we observed an increased number of patients with multiple lesions after high energy accidents. Type C injuries of the thoracic spine are the most severe lesions, with the worse prognosis. The study analyzes the injury profile, management and outcome of all patients with thoracic spine, from T1- to T10, type C injuries treated in the Spinal Surgery Department of “Bagdsar- Arseni” Emergency Hospital, in the last 5 years. There were 26 patients admitted in the study, mostly male, 77%, with a mean age of 33.8 years. All of them were victims of high energy accidents, and all had spine injury associated with multiple lesions (head, thoracic, abdominal and limbs. We have chosen a posterior approach in all cases, with laminectomy or hemilaminectomy, permitting us to achieve all the major objectives of surgery, with the advantage of lower blood loss and a reduced operating time. The purpose of surgery was to achieve decompression of the spinal cord and stability of the thoracic spine. We treated 19 patient surgically and 4 patient conservative. Thoracic spine type C fractures remain a challenge for the spinal surgeon. These lesions require a multidisciplinary team approach for the treatment of associated lesions. The main goal of surgery is to achieve stability of the fractured segments. The timing for surgery is indicated mainly by associated respiratory problems.

    The purpose of this study is to investigate the mechanism of the formation for thoracic impedance change. On the basis of Ohm's law and the electrical field distribution in the cylindrical volume conductor, the formula about the thoracic impedance change are deduced, and they are demonstrated with the model experiment. The results indicate that the thoracic impedance change caused by single blood vessel is directly proportional to the ratio of the impedance change to the basal impedance of the blood vessel itself, to the length of the blood vessel appearing between the current electrodes, and to the basal impedance between two detective electrodes on the chest surface, while it is inversely proportional to the distance between the blood vessel and the line joining two detective electrodes. The thoracic impedance change caused by multiple blood vessels together is equal to the algebraic addition of all thoracic impedance changes resulting from the individual blood vessels. That is, the impedance changes obey the principle of adding scalars in the measurement of the electrical impedance graph. The present study can offer the theoretical basis for the waveform reconstruction of Impedance cardiography (ICG).

    Thoracic outlet syndrome refers to compression of one or more of the neurovascular structures traversing the superior aperture of the thoracic cavity. A symptom-based patient-directed questionnaire was used to evaluate the outcome of the supraclavicular approach for treatment of neurogenic thoracic outlet syndrome. A prospective study was performed between April 2007 and October 2010. During this period, 97 patients in different age groups, with signs and symptoms of thoracic outlet syndrome, were surgically treated by the supraclavicular approach. The patients were aged between 14 and 60 years (mean 32.5 years), and the majority were female (89.69%). Surgery was performed on the left side in 52 patients and on the right side in 48, including 3 who had bilateral operations. The median follow-up was 11.2 months. In 78% of the 100 operations, excellent improvement in symptoms was noted, there was partial improvement in 18%, and 4% resulted in no response. First rib resection remains an important and essential step in the management of the thoracic outlet syndrome, in the absence of bony abnormalities. The supraclavicular approach can be employed with minimal morbidity and an excellent outcome.

    Full Text Available We describe a female patient who presented with watering followed by swelling in the left infraorbital area of 5 years duration. She had previously been prescribed topical antibiotics on several occasions with no improvement. On pressure over the swelling, there was blood-tinged discharge from the left eye and nostril. Magnetic resonance imaging revealed an enhancing, well-defined mass lesion in the inferomedial aspect of the left orbit, likely of nasolacrimal origin. Computed tomography dacryocystogram with three-dimensional reconstruction showed a well-circumscribed mass with an irregular surface, originating from the lacrimal sac. Gram staining and potassium hydroxide mount from the regurgitant fluid revealed thick-walled cysts with sporangia suggestive of Rhinosporidium seeberi infection. Excision biopsy of the lesion confirmed R. seeberi as the causative agent. The patient has been put on long-term dapsone therapy to prevent a recurrence and has been asked to follow-up 6 months later.

    To assess the morphology of thoracic aorta, we had a trial of Gd-DTPA enhanced ultrafast cine MR imaging on the thoracic aorta. This method was provided with high quality thoracic aortogram during 15-20 seconds. In patients without hypertension and aortic valve disease, dimensions of ascending aorta and aortic arch were significantly correlated with aging. In patients with hypertension, dimensions of ascending aorta and aortic arch were significantly dilated. In patients with aortic valve disease, thoracic aorta was diffusely enlarged, especially in ascending aorta. Gd-DTPA enhanced ultrafact cine MR imaging was useful to assess the thoracic aortic anatomy and diseases. (author)

    Full Text Available A woman in her mid-60s presented with a bulky mass on the anterior abdominal wall. She had a previous incidental diagnosis of endometrial adenocarcinoma FIGO stage IB following a vaginal hysterectomy. Physical exam and imaging revealed a well circumscribed bulging tumour at the umbilical region, measuring 10 × 9 × 9 cm, with overlying intact skin and subcutaneous tissue. Surgical resection was undertaken, and histological examination showed features of endometrial carcinoma. She began chemotherapy and is alive with no signs of recurrent disease one year after surgery. This case brings up to light an atypical location of a solitary metastasis of endometrial carcinoma.

    2015-01-01

    Full Text Available We describe the case of a 23-year-old man presenting with recurrent pleuritic chest pain and prolonged fever after electrophysiology testing and placement of an implantable cardioverter-defibrillator because of a suspected arrhythmogenic right ventricular dysplasia. The clinical suspicion was initially directed toward pneumonia with pleural effusion and later toward an infection of the cardiac device complicated by septic pulmonary embolism. The definitive diagnosis of pulmonary embolism and infarction was suggested by a point-of-care thoracic sonography, performed at the bedside by a clinician caring for the patient, and then confirmed by contrast enhanced computed tomography, which also showed thrombosis of the left iliofemoral vein, site of percutaneous puncture for cardiac catheterization. Prolonged fever was attributable to a concomitant Epstein-Barr virus primary infection that acted as confounding factor. The present report confirms the value of bedside thoracic sonography in the diagnostic evaluation of patients with nonspecific respiratory symptoms.

    Frilot, Clifton; Kim, Paul Y.; Carrubba, Simona; McCarty, David E.; Chesson, Andrew L.; Marino, Andrew A.

    Analysis of Brain Recurrence (ABR) is a method for extracting physiologically significant information from the electroencephalogram (EEG), a non-stationary electrical output of the brain, the ultimate complex dynamical system. ABR permits quantification of temporal patterns in the EEG produced by the non-autonomous differential laws that govern brain metabolism. In the context of appropriate experimental and statistical designs, ABR is ideally suited to the task of interpreting the EEG. Present applications of ABR include discovery of a human magnetic sense, increased mechanistic understanding of neuronal membrane processes, diagnosis of degenerative neurological disease, detection of changes in brain metabolism caused by weak environmental electromagnetic fields, objective characterization of the quality of human sleep, and evaluation of sleep disorders. ABR has important beneficial implications for the development of clinical and experimental neuroscience.

    We here report a rare case of synovial sarcoma of the chest wall. A 71-year-old Japanese woman noticed a left anterior chest wall mass after twice having had surgery for lung cancer. An aspiration biopsy diagnosed synovial sarcoma. She then underwent a surgical resection. Pathology examination revealed a biphasic-type synovial sarcoma. When the prepared RNA from the tumor was subjected to a polymerase chain reaction, SYT-SSX1 fusion gene transcripts were demonstrated. Patients with the SYT-SSX1 fusion gene have a worse clinical outcome than patients with SYT-SSX2-positive tumors. After a second surgery, performed in 1 year later, there was no evidence of recurrence for 30 months; however, careful observation may be required.

    Full Text Available Case 1 is an 18 year-old woman with a third recurrence of a left congenital diaphragmatic hernia (CDH. She had previously undergone a primary repair of a recurrence via laparotomy and an additional repair of a second recurrence with PTFE mesh via a thoracotomy. Following her third recurrence she underwent successful laparoscopic repair utilizing composite polyester/collagen (Parietex™ Composite, Covidien, Sofradim, France mesh. Six years following surgery, she has carried a pregnancy to term and has not recurred. Case 2 is a 5 month-old infant who presented with a recurrent right-sided CDH. She initially underwent primary repair via thoracotomy along with a right pneumonectomy at an outside institution. She presented with incarceration of her liver, hepatic venous thrombosis, mediastinal shift, and respiratory distress. She underwent successful repair with composite mesh through a right thoracoabdominal incision. At 8 months post-operatively, she has no evidence of recurrence in spite of the expected mediastinal deviation to the right and right thoracic volume loss as a result of being status post right pneumonectomy. Recurrences occur in a significant number of patients following repair of congenital diaphragmatic hernia, particularly cases in which a mesh implant are utilized. Historically, PTFE has been the product of choice for a diaphragmatic implant by pediatric surgeons. However, this product does not incorporate into surrounding tissues which theoretically places patients at risk for recurrence. Polyester/collagen composite mesh has been used for decades in adults undergoing complex groin and ventral hernia repairs with excellent results. However, its use for congenital diaphragmatic hernias has not been previously described. We present the successful utilization of this product in two cases which were at extremely high risk for future recurrence. Additional investigations should be done and long term follow up regarding application of

    Full Text Available Aims: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA has shown excellent diagnostic capabilities for mediastinal and hilar lymphadenopathy. However, its value in thoracic non-lymph node lesions is less clear. This study was designed to assess the value of EBUS-TBNA in distinguishing malignant from benign thoracic non-lymph node lesions. Methods: From October 2009 to August 2011, 552 patients underwent EBUS-TBNA under local anesthesia and with conscious sedation. We retrospectively reviewed 81 of these patients who had tracheobronchial wall-adjacent intrapulmonary or isolated mediastinal non-lymph node lesions. On-site cytological evaluation was not used. Immunohistochemistry (IHC was performed to distinguish the origin or type of malignancy when necessary. Results: EBUS-TBNA was performed in 68 tracheobronchial wall-adjacent intrapulmonary and 13 isolated mediastinal non-lymph node lesions. Of the 81 patients, 77 (95.1%, 60 malignancies and 17 benignancies were diagnosed through EBUS-TBNA, including 57 primary lung cancers, 2 mediastinal tumors, 1 pulmonary metastatic adenocarcinoma, 7 inflammation, 5 tuberculosis, 3 mediastinal cysts, 1 esophageal schwannoma, and 1 focal fibrosis. There were four false-negative cases (4.9%. Of the 60 malignancies, there were 9 (15.0% which originally had no definite histologic origin or type. Thus, IHC was performed, with 7 (77.8% being subsequently confirmed. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EBUS-TBNA in distinguishing malignant from benign lesions were 93.4% (60/64, 100% (17/17, 100% (60/60, 81.0% (17/21, and 95.1% (77/81, respectively. Conclusion: EBUS-TBNA is a safe procedure with a high sensitivity for distinguishing malignant from benign thoracic non-lymph node lesions within the reach of EBUS-TBNA, with IHC usually providing a more definitive diagnosis.

    This study aimed to evaluate the application of 3D printing in assisting preoperative plan of pedicle screw placement for treating middle-upper thoracic trauma. A preoperative plan was implemented in seven patients suffering from middle-upper thoracic (T3-T7) trauma between March 2013 and February 2016. In the 3D printing models, entry points of 56 pedicle screws (Magerl method) and 4 important parameters of the pedicle screws were measured, including optimal diameter (ϕ, mm), length (L, mm), inclined angle (α), head-tilting angle (+β), and tail-tilting angle (-β). In the surgery, bare-hands fixation of pedicle screws was performed using 3D printing models and the measured parameters as guidance. A total of seven patients were enrolled, including five men and two women, with the age of 21-62 years (mean age of 37.7 years). The position of the pedicle screw was evaluated postoperatively using a computerized tomography scan. Totally, 56 pedicle screws were placed, including 33 pieces of level 0, 18 pieces of level 1, 4 pieces of level 2 (pierced lateral wall), and 1 piece of level 3 (pierced lateral wall, no adverse consequences), with a fine rate of 91.0%. 3D printing technique is an intuitive and effective assistive technology to pedicle screw fixation for treating middle-upper thoracic vertebrae, which improve the accuracy of bare-hands screw placement and reduce empirical errors. The trial was approved by the Ethics Committee of the Fujian Provincial Hospital. It was registered on March 1st, 2013, and the registration number was K2013-03-001.

    The treatment of locoregionally recurrent breast cancer in patients who have previously undergone radiation therapy is challenging. Special techniques are often required that both eradicate the disease and minimize the risks of retreatment. We report the case of a patient with an early-stage left breast cancer who developed inflammatory-type recurrence requiring re-irradiation of the chest wall using bolus electron conformal therapy with image-guided treatment delivery. The patient was a 51-year-old woman who had undergone lumpectomy, axillary lymph node dissection, and adjuvant whole-breast radiation therapy for a stage I left breast cancer in June 1998. In March 2009, she presented at our institution with biopsy-proven recurrent inflammatory carcinoma and was aggressively treated with multi-agent chemotherapy followed by mastectomy that left a positive surgical margin. Given the patient's prior irradiation and irregular chest wall anatomy, bolus electron conformal therapy was used to treat her chest wall and draining lymphatics while sparing the underlying soft tissue. The patient still had no evidence of disease 21 months after treatment. Our results indicate that bolus electron conformal therapy is an accessible, effective radiation treatment approach for recurrent breast cancer in patients with irregular chest wall anatomy as a result of surgery. This approach may complement standard techniques used to reduce locoregional recurrence in the postmastectomy setting.

  18. Thoracic sympathectomy for hyperhidrosis: from surgical indications to clinical results

    Araújo, José Augusto

    2017-01-01

    Sympathectomy and its variations have been performed in thoracic surgery for more than 100 years. However, its indications have undergone profound modifications in this period. Likewise, since then the surgical technique has also evolved dramatically up to the minimally invasive techniques worldwide accessible in present days. Currently, primary hyperhidrosis is, by far, the main indication for thoracic sympathectomy and this procedure is usually carried out thoracoscopically with excellent results. However, until today, hyperhidrosis is a part of thoracic surgery still surrounded by controversy, persisting as an open field over which some confusion still resides regarding its pathophysiology, terms definitions and operative approaches. The aim of this article is to provide a wide but easily comprehensible review of the theme, discussing and clarifying the major concepts with respect to its clinical presentation, all the presently available treatment options and strategies with their potential benefits and risks, the adequate patient selection for sympathectomy, as well as the postoperative clinical results.

    2017-01-01

    Neurogenic thoracic outlet syndrome is a widely recognized, yet controversial, syndrome. The lack of specific objective diagnostic modalities makes diagnosis difficult. This is compounded by a lack of agreed upon definitive criteria to confirm diagnosis. Recent efforts have been made to more clearly define a set of diagnostic criteria that will bring consistency to the diagnosis of neurogenic thoracic syndrome. Additionally, advancements have been made in the quality and techniques of various imaging modalities that may aid in providing more accurate diagnoses. Surgical decompression remains the mainstay of operative treatment; and minimally invasive techniques are currently in development to further minimize the risks of this procedure. Medical management continues to be refined to provide non-operative treatment modalities for certain patients, as well. The aim of the present work is to review these updates in the diagnosis and treatment of neurogenic thoracic outlet syndrome. PMID:28555024

    Objective: To evaluate the efficacy of pleural abrasion in treatment of spontaneous pneumothorax with video-assisted thoracic surgery (VATS) for bullae resection. Methods: The clinical data of 158 patients with initial spontaneous pneumothorax who underwent video-assisted thoracic wedge resections with or without pleural abrasion in Henan Provincial People's Hospital from June 2010 to June 2015 were retrospectively analyzed. The patients were assigned to two equal groups according to whether pleural abrasion was applied or not: experimental group (with pleural abrasion) and control group (without pleural abrasion); and there were 79 patients in each group.There were 62 males and 17 females aged 15-60 years (mean age 34 years) in pleural abrasion group. And there were 70 males and 9 females aged 18-60 years (mean age 38 years) in non-pleural abrasion group.After surgery, all patients were evaluated for postoperative pain, chest tube removal time, hospital stay and other complications.Independent samples t test was used to compare the data between groups. Results: Surgeries for 158 patients were performed successfully.No mortality occurred.There was no conversion to thoracotomy.Postoperative pain, operation time, intraoperative blood loss, chest tube removal time, pleural canals flowand average hospital stay in non-pleural abrasion group was significantly lower for 4.4, 19 minutes, 10 ml, 21 hours, 87 ml and 1.4 days respectively when compared with those in pleural abrasion group ( t =32.478, 7.140, 11.093, 7.288, 10.246, 8.070, all P tube removal time and hospital stay in non-pleural abrasion group are all lower than those in pleural abrasion group.And there is no significant difference in the recurrence of pneumothorax between the two groups after VATS bullae resection.

    2000-01-01

    Introduction: Pneumothorax (PTX) occurs commonly in trauma patients and is confirmed by examination and radiography. Thoracic ultrasound (VIS) has been suggested as an alternative method for rapidly diagnosing PTX when X-ray is unavailable as in rural, military, or space flight settings; however, its accuracy and specificity are not known. Methods: We evaluated the accuracy of thoracic U/S detection of PTX compared to radiography in stable, emergency patients with a high suspicion of PTX at a Level-l trauma center over a 6-month period. Following University and NASA Institutional Review Board approval, informed consent was obtained from patients with penetrating or blunt chest trauma, or with a history consistent with PTX. Whenever possible, the presence or absence of the " lung sliding" sign or the "comet tail" artifact were determined by U/S in both hemithoraces by residents instructed in thoracic U/S before standard radiologic verification of PTX. Results were recorded on data sheets for comparison to standard radiography. Results: Thoracic VIS had a 94% sensitivity; two PTX could not be reliably diagnosed due to subcutaneous air; the true negative rate was 100%. In one patient, the VIS exam was positive while X ray did not confirm PTX; a follow-up film 1 hour later demonstrated a small PTX. The average time for bilateral thoracic VIS examination was 2 to 3 minutes. Conclusions: Thoracic ultrasound reliably diagnoses pneumothorax. Presence of the "lung sliding" sign conclusively excludes pneumothorax. Expansion of the FAST examination to include the thorax should be investigated.

    As an option for minimally invasive thoracic surgery, robot-assisted thoracic surgery (RATS) has shown comparable perioperative outcomes to those achieved by traditional video-assisted thoracic surgery (VATS). It is unknown whether RATS might have any potential benefits in more complex thoracic surgical procedures, which usually require open surgery instead of VATS. The current study presents a preliminary result regarding the use of RATS in complex thoracic operations in an attempt to address this unresolved question. Data from a prospectively collected and maintained surgical database were collected on patients who underwent RATS between February 2012 and August 2014. We defined complex RATS as those operations involving difficult dissections, complex sutures or excision of very large tumors (>8 cm) which would have required open surgery in our hospital before the introduction of RATS. The characteristics and peri-operative outcomes of patients receiving complex RATS were reviewed. Of the 120 patients undergoing RATS, 30 of them were classified as having undergone complex RATS, 21 to remove lung tumors and 9 to remove mediastinal tumors. The indications for complex RATS included 21 difficult dissections, 10 complex sutures, and 7 very large tumors (8 patients had two indications). There are three conversions to thoracotomy for pulmonary arterial bleeding. There was one mortality resulted from post-pneumonectomy pulmonary hypertension and sepsis. Patients with difficult dissection had longer operative time and hospital stay, and more bleeding and postoperative morbidity. RATS for complex thoracic procedures is feasible, especially for complex suturing and excision of very large mediastinal tumors, but more attention is needed for patients needing difficult dissections. Advanced preparation for conversion is necessary during this difficult operation.

    Palmar hyperhidrosis or excessive sweating of the hands causes, to those affected, emotional and physical disturbance and impediment in professional and social life. The cause is unknown. Sweat glands are innervated by the sympathic chain of the autonomous nervous system. The center of sympathic regulation of the upper extremities is located between the segments of D.2-D.9 of the spinal cord. Accepted treatment consists of surgery aimed to excise the third thoracic sympathic ganglion. CT guided chemical percutaneous thoracic sympathectomy presents an alternative, which in the event of failure does not prevent ensuing surgery. The preliminary experience with this procedure in 50 patients is presented and discussed. (orig./GDG).

    Full Text Available Both osteoporotic fractures and pleural effusions are frequently observed in medicine. However, rarely does one associate a hemorrhagic pleural effusion with a thoracic spinal fracture when the patient has not sustained massive trauma. In this paper, we discuss two cases where seemingly insignificant low-energy trauma precipitated massive haemothoraces in elderly patients with underlying osteoporosis, ultimately resulting in their immediate causes of death. This paper serves to remind health care professionals of the importance of using caution when moving elderly patients as well as to consider thoracic spinal fracture as a potential explanation for a hemorrhagic pleural effusion of undetermined etiology.

    We report a case of quadrilateral space syndrome related to thoracic surgery. A 21-year-old man underwent video-assisted thoracic surgery for a left-sided pneumothorax. After the operation, he presented with difficulties in left arm abduction and paresthesia over the lateral aspect of the shoulder and upper arm. Deltoid muscle atrophy and tenderness over the quadrilateral space were also observed. On further examination, he was diagnosed with isolated paralysis of the axillary nerve, the so-called quadrilateral space syndrome. This is a rare complication, but it interferes with the activities of daily living, and thus one should pay attention to this syndrome.

    Blunt traumatic cardiac rupture is rare and associated with high mortality. The most popular theory of cardiac rupture after blunt thoracic trauma is rapid deceleration with disruption of the atria from their connections to the vena cava and pulmonary veins. In cases with both massive hemothorax and hemopericardium, injury can usually originate from the heart and/or major vessels. Surgical approach through the median sternotomy can provide convenience to repair the defect. In this article, successful treatment with median sternotomy of a 33-year-old male case with a rupture of the left atrium after blunt thoracic trauma was reported.

    The radiological findings of 189 cases of Kaposi's sarcoma occurring in patients with AIDS were studied. There was also made pathological correlations in these patients. Interstitial reticular infiltrations were frequently detected on thoracic examination showing paracardiac confluent areas. There was also lymphadenopathy, gross nodules and pleural fluid accumulation. Although there was no detection of any pathognomonic aspect, the interstitial reticular infiltration finding together with the paracardiac confluent areas and associated with gross nodules, is highly indicative to thoracic involvement by the disease.

    Outcomes of surgery for neurogenic thoracic outlet syndrome (NTOS) in workers' compensation are poor in a majority of patients, partly due to nonspecificity of diagnosis. Most cases have no objective evidence of the presence of brachial plexus dysfunction. Up to 20% of patients experience a new adverse event. Objective neurologic signs and electrodiagnostic evidence of brachial plexus dysfunction must be present before proceeding with invasive procedures. This guideline includes objective criteria that must be met before thoracic outlet syndrome surgery can be approved in Washington State. Evidence does not support the use of scalene blocks, botulinum toxin therapy, or vascular studies to diagnose NTOS. Copyright © 2015 Elsevier Inc. All rights reserved.

    Twenty-one dogs with histopathologically confirmed hemangiosarcoma were evaluated by thoracic radiography for metastatic disease. All dogs had histopathologic examinations of the lungs within two weeks of thoracic radiography. Fourteen dogs had histopathologic evidence of pulmonary hemangiosarcoma; metastatic disease was detected radiographically in eleven of these dogs. The most common radiographic pattern was that of poorly defined small coalescing nodules (8 dogs); other radiographic patterns included well-circumscribed nodules (3 dogs) and alveolar infiltrates secondary to hemorrhage (2 dogs). Differential diagnoses for diffuse, poorly defined, coalescing pulmonary opacities should include hemangiosarcoma in addition to edema, lymphoma, systemic mycoses, fibrosis, allergy, toxicosis, and carcinomas

    In recent times, significant effort has been made to understand the mechanical behaviour of the arterial wall and how it is affected by the different vascular pathologies. However, to be able to interpret the results correctly, it is essential that the influence of other factors, such as aging or anisotropy, be understood. Knowledge of mechanical behaviour of the aorta has been customarily constrained by lack of data on fresh aortic tissue, especially from healthy young individuals. In addition, information regarding the point of rupture is also very limited. In this study, the mechanical behaviour of the descending thoracic aorta of 28 organ donors with no apparent disease, whose ages vary from 17 to 60 years, is evaluated. Tensile tests up to rupture are carried out to evaluate the influence of age and wall anisotropy. Results reveal that the tensile strength and stretch at failure of healthy descending aortas show a significant reduction with age, falling abruptly beyond the age of 30. This fact places age as a key factor when mechanical properties of descending aorta are considered

    Our objective was to describe the CT findings of thoracic Wegener's granulomatosis. At presentation, both conventional and thin-section CT scans were available in 30 patients with Wegener's granulomatosis. Serial CT scans (range of intervals: 1-25 months, mean 4.5 months) were available in 20 patients. The initial and follow-up CT scans were analyzed retrospectively by two observers in terms of pattern and extent of parenchymal and airway lesions. Positive CT findings were seen in 29 of 30 (97%) patients at initial presentation. The most common pattern was nodules or masses seen in 27 of 30 (90%) patients. They were multiple in 23 of 27 (85%) patients, bilateral in 18 (67%), subpleural in 24 (89%), and peribronchovascular in 11 (41%) in distribution. Bronchial wall thickening in the segmental or subsegmental bronchi was seen in 22 (73%) patients. Large airways were also abnormal in 9 (30%) patients. Patchy areas of consolidation and ground-glass opacity were seen in 7 (23%) patients, respectively. In 17 of 20 (85%) patients in whom follow-up CT scans were available, the parenchymal or airway lesion showed complete or partial improvement with treatment. The CT findings of Wegener's granulomatosis, although multiple and variable, consist mainly of bilateral subpleural or peribronchovascular nodules or masses and bronchial wall thickening in the segmental or subsegmental bronchi. Parenchymal and airway lesions improve with treatment in most patients. (orig.)

    Purpose: To suppress the amount of heat released from a pressure vessel and reliably shield neutron fluxes and gamma rays from a reactor core by the addition of cooling ducts in a thermal shielding wall provided with a blower and an air cooling cooler. Constitution: A thermal shielding wall is located on a pedestal so as to surround a pressure vessel and the pressure vessel is located by way of a skirt in the same manner. Heat insulators are disposed between the pressure vessel and the shielding wall while closer to the skirt in the skirt portion and closer to the shielding wall in the vessel body portion. A plurality of cooling ducts are arranged side by side at the inner side in the shielding wall. A through-duct radially passing through the wall is provided in the lower portion thereof and a blower fan for cooling air and a cooler for cooling returned air are connected by way of a communication duct to the other end of the through-duct. This enables to provide a shielding wall capable of suppressing the amount of heat released from the pressure vessel as much as possible and giving more effective cooling. (Kawakami, Y.)

A prospective, nonrandomized, multicenter trial using the Medtronic Valiant Captivia stent graft was conducted at 20 sites in North America. Fifty patients with blunt thoracic aortic injuries were enrolled between April 2010 and January 2012 and will be followed for 5 years. The injuries were classified into categories (grades I-IV) based on severity: intimal tear, intramural hematoma, pseudoaneurysm, or rupture. The primary end point was 30-day all-cause mortality. Secondary end points were adverse events occurring within 30 days that were related to the procedure, device or aorta, and aortic-related mortality. Technical success was measured as successful device delivery and deployment. Seventy-six percent (38/50) of patients were male with mean age of 41 ± 17 years. Fifty-one Medtronic Valiant Captivia thoracic stent grafts and a single Talent thoracic stent graft were implanted within a median of 1.0 days following injury (mean, 1.8 ± 4.0 days). Seventy percent (35/50) of aortic injuries were grade III or higher, including one patient with free rupture. Mean injury severity score was 38 ± 14. Fifty-four percent of stent grafts were ≤26 mm (28/52). The left subclavian artery was completely covered in 40% of patients (20/50) and partially covered in 18% of patients (9/50). Four patients underwent subclavian artery revascularization: one at the time of the endograft procedure and three others after developing arm ischemia after the initial endograft procedure. Cerebral spinal fluid was drained in two patients. The median procedure time was 91 minutes, and median hospital stay was 12 days. There was 100% successful device delivery and deployment. Four (8%) patients died within 30 days. Nonfatal adverse events within 30 days that were related to the procedure, device, or aorta were experienced by 12% (6/50) of patients. No nonfatal

    Recurrent respiratory papillomatosis is a disease caused by a virus in the Papovaviridae family. It tends to recur in the laryngotracheal tree, and treatment is surgical removal with a CO2 laser and suspension microlaryngoscopy. Some patients may require these procedures every few weeks, and a systemic agent to control disease would be ideal for them. Care must be taken in the selection of an agent, as these lesions, similar to other papova virus-induced lesions, are most susceptible to malignant degeneration in the presence of a carcinogen. Eight patients were given 10 courses of polyriboinosinic-polyribocytidylic acid [poly(I,C)-LC] in an attempt to control their disease. The three who were tested were able to produce good titers of interferon. The rate of disease progression was probably slowed in four patients, as reflected by a decrease in the requirement for surgery; however, the medication appeared to be relatively toxic in effective doses. Four of 10 courses were held for hepatotoxicity, and mild hepatotoxicity occurred in four more. One course was held for thrombocytopenia associated with bleeding at the tracheostomy site. We conclude that in its presently available form, poly(I,C)-LC is too toxic to be administered long term for control of this disease.

    Abdominal wall hernias are very common diseases encountered in surgical practice. Groin hernia is the commonest type of abdominal wall hernias. There are several methods of hernia repair but tension-free repair (usually with mesh) offers the least recurrent rate. To describe the clinical profile of anterior abdominal wall hernias and our experience in the surgical management of identified hernias. The project was a retrospective study of all patients with abdominal wall hernia presenting into surgical divisions of University College Hospital Ibadan during a 6 year period (January 2008 to December 2013). Relevant information was retrieved from their case notes and analysed. The case records of 1215 (84.7%) patients out of 1435 were retrieved. Elective surgery was done in 981(80.7%) patients while 234 (19.3%) patients had emergency surgery. There were 922 (84.8%) groin hernias and post-operative incisional hernia accounted for 9.1% (111) of the patients. About half (49.1%) of those with incisional hernia were post obstetric and gynaecologic procedure followed by post laparotomy incisional hernias 16 (14%) and others (23.5%). The ratio of inguinal hernia to other types in this study is 3:1. Hollow viscus resection and emergency surgery were predictors of wound infection statistically significant in predicting wound infection (P < 0.001). Peri-operative morbidity/mortality at 28 days post operation was documented in 113 patients (12.1%). One year recurrence rate of groin hernia was 2.1%. The pattern of presentation and management of anterior wall hernias are still the same compared with the earlier study in this hospital. New modality of treatment should be adopted as the standard choice of care. Abdominal wall hernias are very common clinical presentation. Modified Bassini repair was the preferred method of repair due to its simplicity. Mesh repair is becoming more common in recent time but high cost and initial non-availability of the mesh limit its use in our centre.

    The plasma wall interactions for two extreme cases, the 'vacuum model' and the 'cold gas blanket' are outlined. As a first step for understanding the plasma wall interactions the elementary interaction processes at the first wall are identified. These are energetic ion and neutral particle trapping and release, ion and neutral backscattering, ion sputtering, desorption by ions, photons and electrons and evaporation. These processes have only recently been started to be investigated in the parameter range of interest for fusion research. The few measured data and their extrapolation into regions not yet investigated are reviewed

    Segmental instability due to lumbar spondylolisthesis is a potential cause of chronic low back pain. Hypomobility of the spine results in compensatory segmental hypermobility of the segment above or below restricted segments. Therefore, the aim of the study is to determine the effects of mobilisation of the hypomobile upper thoracic spine along with conventional flexion exercises and stretching of short hip flexors on the degree of slippage and the functions of the persons with lumbar spondylolisthesis. All patients with spondylolisthesis were randomly assigned into two groups: Group I - Experimental group, treated with mobilisation of the thoracic spine along with the conventional physiotherapy and Group II - Conventional group, treated with conventional stretching, strengthening, and lumbar flexion exercise programme. The experimental group treated with mobilisation of the thoracic spine shows a significant reduction in the percentage of vertebral slip from pre-treatment to post-treatment measurements. Low back pain due to spondylolisthesis may be benefited by mobilisation of the thoracic spine along with stretching of short hip flexors, piriformis, lumbar flexion range of motion exercises, core strengthening exercises, etc. Copyright © 2016 Elsevier Ltd.

    2013-01-01

    Full Text Available Background: Operative intervention for thoracic trauma typically requires thoracotomy. We hypothesized that thoracoscopy may be safely and effectively utilized for the acute management of thoracic injuries. Materials and Methods: The Trauma Registry of a Level I trauma center was queried from 1999 through 2010 for all video-assisted thoracic procedures within 24 h of admission. Data collected included initial vital signs, operative indication, intraoperative course, and postoperative outcome. Results: Twenty-three patients met inclusion criteria: 3 (13% following blunt injury and 20 (87% after penetrating trauma. Indications for urgent thoracoscopy included diaphragmatic/esophageal injury, retained hemothorax, ongoing hemorrhage, and open/persistent pneumothorax. No conversions to thoracotomy were required and no patient required re-operation. Mean postoperative chest tube duration was 2.9 days and mean length of stay was 5.6 days. Conclusion: Video-assisted thoracoscopic surgery is safe and effective for managing thoracic trauma in hemodynamically stable patients within the first 24 h post-injury.

    2015-04-01

    Full Text Available INTRODUCTION: Optimum treatment for postoperative pain has been of fundamental importance in surgical patient care. Among the analgesic techniques aimed at this group of patients, thoracic paravertebral block combined with general anesthesia stands out for the good results and favorable risk-benefit ratio. Many local anesthetics and other adjuvant drugs are being investigated for use in this technique, in order to improve the quality of analgesia and reduce adverse effects. OBJECTIVE: Evaluate the effectiveness and safety of paravertebral block compared to other analgesic and anesthetic regimens in women undergoing breast cancer surgeries. METHODS: Integrative literature review from 1966 to 2012, using specific terms in computerized databases of articles investigating the clinical characteristics, adverse effects, and beneficial effects of thoracic paravertebral block. RESULTS: On the selected date, 16 randomized studies that met the selection criteria established for this literature review were identified. Thoracic paravertebral block showed a significant reduction of postoperative pain, as well as decreased pain during arm movement after surgery. CONCLUSION: Thoracic paravertebral block reduced postoperative analgesic requirement compared to placebo group, markedly within the first 24 h. The use of this technique could ensure postoperative analgesia of clinical relevance. Further studies with larger populations are necessary, as paravertebral block seems to be promising for preemptive analgesia in breast cancer surgery.

    Mondini dysplasia is a congenital malformation of the inner ear, commonly associated with hearing impairment, cerebrospinal fluid otorrhea/rhinorrhea and recurrent meningitis. Two such cases are described, with hearing impairment, cerebrospinal fluid rhinorrhea, and several episodes of meningitis. Diagnosis was confirmed by high-resolution computed tomography. After surgical correction of the malformation, there was no recurrent episode of meningitis at subsequent follow-up. To avoid the suffering and the sequelae of recurrent meningitis, an early diagnosis and prompt surgical intervention are crucial for such patients.

    2017-10-01

    Aorto-esophageal fistula (AEF) is a rare and lethal entity, and the difficulty of making diagnosis of AEF is well-known. As promising results in the short-term effectiveness of thoracic endovascular aortic repair (TEVAR) promote its usage, the occurrence of AEF after TEVAR (post-TEVAR AEF) increases as one of the major complications. Therefore, we provide a review concerning the management strategy of post-TEVAR AEF. Although its representative symptom was reported as the triad of mid-thoracic pain and sentinel hematemesis followed by massive hematemesis, the symptom-free interval between sentinel hemorrhage and massive exsanguination is unpredictable. However, the physiological condition represents a surgical contraindication. Accordingly, early diagnosis is important, but either CT or esophago-gastro-duodenoscopy rarely depicts a typical image. The formation of post-TEVAR AEF might be associated with the infection of micro-organisms, which is uncontrollable with anti-biotic administration. The current first-line strategy is combination therapy as follows, (1) to control bleeding by TEVAR in the urgent phase, and (2) radical debridement and aortic/esophageal re-construction in the semi-urgent phase. In view of the high mortality and morbidity rate, it is proposed that the choice in treatment strategies might be affected by patient`s condition, size of the wall defects and the etiology of AEF. Practically, we should keep in mind the importance of making an early diagnosis and, once a suspicious symptom has occurred in a patient with a history of TEVAR, the existence of post-TEVAR AEF should be suspected. A prospective registry together with more developed technologies will be needed to establish a future strategy.

    Purpose: To evaluate the feasibility and efficacy of percutaneous interstitial brachytherapy using iodine-125 ( 125 I) radioactive seeds under computed tomographic (CT) guidance for malignant thoracic tumors. Materials and methods: Forty-one patients (34 males, 7 females; 18–90 years; mean, 63.7 years) with 77 lesions (3 in the mediastinum, 7 in the chest wall, 67 in the lung) underwent percutaneous interstitial implantation of 125 I radioactive seeds under CT guidance. A treatment planning system (TPS) was employed to calculate the number and distribution of seeds preoperatively. An 18-G needle was inserted into the lesions under CT guidance and send the seeds according to TPS. Two patients with mediastinal lesions undergoing seed implantation received an artificial pneumothorax. One patient with lung carcinoma adjacent to the anterior mediastinum underwent seed implantation through the sternum. Follow-up CT was done every 2 months postoperatively. Results: The procedure was successful in all patients. No major procedure-associated death occurred. The mean duration of follow-up was 19.4 ± 1.3 months (3–49 months). A complete response (CR) was seen in 49 lesions (63.6%), partial response (PR) in 9 lesions (11.7%), stable disease (SD) in 12 lesions (12.8%), and progressive disease (PD) in 7 lesions (7.4%). The overall response rate (CR + PR) was 75.3%; the local control rate (CR + PR + SD) was 90.9%. The 1-, 2- and 3-year progression-free rates for local tumors were 91%, 88% and 88%, respectively. The 1-, 2- and 3-year survival rates were 87%, 74% and 68%, respectively. Conclusion: Implantation of CT-guided 125 I seeds is feasible and effective for patients with malignant thoracic tumors

    Full Text Available Our basic understanding of ascending thoracic aortic aneurysm (ATAA pathogenesis is still very limited, hampering early diagnosis, risk prediction, and development of treatment options. "Omics"-technologies, ideal to reveal tissue alterations from the normal physiological state due to disease have hardly been applied in the field. Using a metabolomic approach, with this study the authors seek to define tissue differences between controls and various forms of ATAAs.Using a targeted FIA-MS/MS metabolomics approach, we analysed and compared the metabolic profiles of ascending thoracic aortic wall tissue of age-matched controls (n = 8, bicuspid aortic valve-associated aneurysms (BAV-A; n = 9, tricuspid aortic valve-associated aneurysms (TAV-A; n = 14, and tricuspid aortic valve-associated aortic dissections (TAV-Diss; n = 6.With sphingomyelin (SM (OH C22:2, SM C18:1, SM C22:1, and SM C24:1 only 4 out of 92 detectable metabolites differed significantly between controls and BAV-A samples. Between controls and TAV-Diss samples only phosphatidylcholine (PC ae C32:1 differed. Importantly, our analyses revealed a general increase in the amount of total sphingomyelin levels in BAV-A and TAV-Diss samples compared to controls.Significantly increased levels of sphingomyelins in BAV-A and TAV-Diss samples compared to controls may argue for a repression of sphingomyelinase activity and the sphingomyelinase-ceramide pathway, which may result in an inhibition of tissue regeneration; a potential basis for disease initiation and progression.

    Full Text Available To review our experience in treatment of patients with thoracic empyema at a teaching hospital chart of patients were retrospectively reviewed over a 72-month period. A total of 112 patients (94 men, 18 women, mean age: 39, range: 6-89 years underwent therapeutic procedures for thoracic empyema between 2001-2006. The causes of empyema included parapneumonic empyema (60.7%, thoracic trauma (20.5%, surgical procedures (7.1% and seeding from an extra-pulmonary source (11.7%. Multiloculated empyemas were documented in 45 patients (40%. Insertion of chest tube was the first procedure in 103 patients (92%. Nineteen patients (17% were treated by thoracotomy, ten patients (8.9% had fibrinolytic therapy, eight patients (7.2% underwent video assisted thoracic surgery (VATS and sixteen patients (14.3% had subsequent radiologic-guided drainage. Thoracotomy-Decortication was successful in 90% of patients undergoing surgery and the least successful intervention was tube thoracostomy alone. Twelve of 112 patients (10.7% died in the hospital including one patient in the thoracotomy group. Long-term follow-up was available in 67 patients including all of patients requiring surgery and fibrinolytic therapy. Thirty four patients (50% obtained complete functional recovery. Simple drainage as the first procedure for the treatment of thoracic empyema has a high failure rate. Selection of a therapeutic option should be based on age, underlying disease, stage of the empyema, state of the loculation, local expertise and availability. Surgical procedures such as VATS or thoracotomy are recommended as the first procedure in elderly patients and advanced empyema.

    In an effort to stimulate residents and trainers to increase their use of simulation training and the Thoracic Surgery Curriculum, a gamification strategy was developed in a friendly but competitive environment. "Top Gun." Low-fidelity simulators distributed annually were used for the technical competition. Baseline and final video assessments were performed, and 5 finalists were invited to compete in a live setting from 2013 to 2015. "Jeopardy." A screening examination was devised to test knowledge contained in the Thoracic Surgery Curriculum. The top 6 2-member teams were invited to compete in a live setting structured around the popular game show Jeopardy. "Top Gun." Over 3 years, there were 43 baseline and 34 final submissions. In all areas of assessment, there was demonstrable improvement. There was increasing evidence of simulation as seen by practice and ritualistic behavior. "Jeopardy." Sixty-eight individuals completed the screening examination, and 30 teams were formed. The largest representation came from the second-year residents in traditional programs. Contestants reported an average in-training examination percentile of 72.9. Finalists reported increased use of the Thoracic Surgery Curriculum by an average of 10 hours per week in preparation. The live competition was friendly, engaging, and spirited. This gamification approach focused on technical and cognitive skills, has been successfully implemented, and has encouraged the use of simulators and the Thoracic Surgery Curriculum. This framework may capitalize on the competitive nature of our trainees and can provide recognition of their achievements. Copyright © 2015 The American Association for Thoracic Surgery.

    Chest-wall invading malignancies usually necessitate the resection of the respective part of the thoracic wall. Gore-Tex® is the material of choice that is traditionally used to repair thoracic defects. This material is well accepted by the recipient; however, though not rejected, it is an inert material and behaves like a 'foreign body' within the thoracic wall. By contrast, there are materials that have the potential to physiologically integrate into the host, and these materials are currently under in vitro and also in vivo investigation. These materials offer a gradual but complete biodegradation over time, and severe adverse inflammatory responses can be avoided. Here, we present a novel material that is a biodegradable nanocomposite based on poly-lactic-co-glycolic acid and amorphous calcium phosphate nanoparticles in comparison to the traditionally employed Gore-Tex® being the standard for chest-wall replacement. On a mouse model of thoracic wall resection, that resembles the technique and localization applied in humans, poly-lactic-co-glycolic acid and amorphous calcium phosphate nanoparticles and Gore-Tex® were implanted subcutaneously and additionally tested in a separate series as a chest-wall graft. After 1, 2, 4 and 8 weeks cell infiltration into the respective materials, inflammatory reactions as well as neo-vascularization (endothelial cells) were determined in six different zones. While Gore-Tex® allowed for cell infiltration only at the outer surface, electrospun poly-lactic-co-glycolic acid and amorphous calcium phosphate nanoparticles were completely penetrated by infiltrating cells. These cells were composed mainly by macrophages, with only 4% of giant cells and lymphocytes. Total macrophage count increased by time while the number of IL1-β-expressing macrophages decreased, indicating a protective state towards the graft. As such, poly-lactic-co-glycolic acid and amorphous calcium phosphate nanoparticles seem to develop ideal

    The recent improvements in chemotherapy and surgical resection in Ewing sarcoma (ES) increased the overall survival as well as the importance of chest wall reconstruction. These improvements are in order to avoid asymmetrical growth, functional and cosmetic compromise after surgery. Chest wall reconstruction still remains a big issue in young patients with ES. We present a case of ES of the left chest wall, arising from a rib, in a 14-year-old patient. He was admitted after neoadjuvant chemotherapy and radiotherapy. The patient underwent a chest wall resection of three ribs and a wedge lung resection of the upper lobe followed by chest wall reconstruction with Stratos™ rib titanium prostheses. This new device is suitable for reconstruction after major chest wall resection with good cosmetic and functional results. During the follow-up, there was no evidence of local and distant recurrence, the pain was under control and there were no functional alterations in the chest wall.

    To assess the capability of digital tomosynthesis (DTS) as a problem-solving imaging technique to confirm or exclude potential thoracic lesions based on chest x-ray radiography (CXR). Four hundred and-sixty five patients (263 male, 202 female; age, 72.47 ± 11.33 years) with suspected thoracic lesion(s) after the initial onsite analysis of CXR underwent DTS. Two independent readers prospectively analyzed in consensus CXR and DTS images on a picture archiving and communications system-integrated workstation and proposed a diagnosis according to a confidence score for each lesion: 1 or 2 = definite or probable pulmonary or pleural benign lesion or pseudolesion deserving no further diagnostic work-up; 3 = indeterminate; 4 or 5 = probable or definite pulmonary lesion deserving further diagnostic work-up by computed tomography (CT). In patients who did not undergo chest CT, the DTS findings had to be confirmed by 6 to 12 months' imaging follow-up. Finally, 229 pulmonary lesions (193 thoracic and 36 pleural lesions) and 236 pseudolesions were identified. Based on DTS images, readers correctly classified all pseudolesions except for 10/236 (reader 1) or 11/236 (reader 2) pseudolesions and 7 (reader 1) or 6 (reader 2) pulmonary subpleural lesions located in the anterior or posterior lung region close to the thoracic wall. Chest CT was performed in 127/465 (27%) patients, whereas in 338/465 patients (73%) CXR doubtful findings were resolved by DTS. DTS allowed to exclude most pseudolesions initially considered as potential thoracic lesions on the preliminary onsite assessment of CXR and allowed to exclude pulmonary lesions deserving CT assessment in about three fourths of the patients.

    Vertebral hemangiomas are common benign vascular tumors of the spine. It is very rare for these lesions to symptomatically compress neural elements. If spinal cord compression does occur, it usually involves only a single level. Multilevel vertebral hemangiomas causing symptomatic spinal cord compression have never been reported in the pediatric population to the best of our knowledge. We report the case of a 15-year-old boy presenting with progressive paraparesis due to thoracic spinal cord compression from a multilevel thoracic hemangioma (T5-T10) with epidural extension. Because of his progressive neurological deficit, he was initially treated with urgent multilevel decompressive laminectomies from T4 to T11. This was to be followed by radiotherapy for residual tumor, but the patient was unfortunately lost to follow-up. He re-presented 3 years later with recurrent paraparesis and progressive disease. This was treated with urgent radiotherapy with good response. As of 6 months follow-up, he has made an excellent neurological recovery. In this report, we present the first case of a child with multilevel vertebral hemangiomas causing symptomatic spinal cord compression and review the literature to detail the pathophysiology, management, and treatment of other cases of spinal cord compression by vertebral hemangiomas.

    The goals of this review were to determine the incidence of recurrent shoulder dystocia and the incidence of brachial plexus injury in such cases. A search of PubMed was conducted between 1980 and March 2009. Odds ratios (OR) and 95% confidence intervals (CI) were calculated. The search yielded 191 publications, of which 9 provided complete data; these were used to calculate the incidence of recurrent shoulder dystocia. The rate of shoulder dystocia in the prior pregnancies was 1.64% (31,311/1,911,014). Among 10,591 known subsequent vaginal births, the rate of recurrent shoulder dystocia was 12% (OR, 8.25; 95% CI, 7.77, 8.76). Brachial plexus injury occurred significantly more often during recurrent shoulder dystocia than during the first shoulder dystocia (4% vs. 1%; OR, 3.59; 95% CI, 2.44, 5.29; or 45/1000 vs. 13/1000 births). About 12% of parturients with a history of shoulder dystocia have a recurrent dystocia in the subsequent pregnancy, a risk of about 1 in 8. Brachial plexus injury occurs in 19/1000 vaginal births during the first episode of shoulder dystocia, and in 45/1000 vaginal births after recurrent dystocia. Obstetricians & Gynecologist, Family Physicians. After completion of this educational activity, the reader will be able to compare the risk of primary versus recurrent shoulder dystocia. Formulate counseling and treatment strategies for pregnant women who have had a prior pregnancy complicated by shoulder dystocia. Assess the strength of the evidence suggesting the risk of recurrent shoulder dystocia.

    Degradation of the wall of human ascending thoracic aorta has been assessed through Optical Coherence Tomography (OCT). OCT images of the media layer of the aortic wall exhibit micro-structure degradation in case of diseased aortas from aneurysmal vessels or in aortas prone to aortic dissections. The degeneration in vessel walls appears as low-reflectivity areas due to the invasive appearance of acidic polysaccharides and mucopolysaccharides within a typical ordered microstructure of parallel lamellae of smooth muscle cells, elastin and collagen fibers. An OCT indicator of wall degradation can be generated upon the spatial quantification of the extension of degraded areas in a similar way as conventional histopathology. This proposed OCT marker offers a real-time clinical insight of the vessel status to help cardiovascular surgeons in vessel repair interventions. However, the delineation of degraded areas on the B-scan image from OCT is sometimes difficult due to presence of speckle noise, variable SNR conditions on the measurement process, etc. Degraded areas could be outlined by basic thresholding techniques taking advantage of disorders evidences in B-scan images, but this delineation is not always optimum and requires complex additional processing stages. This work proposes an optimized delineation of degraded spots in vessel walls, robust to noisy environments, based on the analysis of the second order variation of image intensity of backreflection to determine the type of local structure. Results improve the delineation of wall anomalies providing a deeper physiological perception of the vessel wall conditions. Achievements could be also transferred to other clinical scenarios: carotid arteries, aorto-iliac or ilio-femoral sections, intracranial, etc.

    Cervical scar contracture causes both physical and psychological distress for burn patients. Many pedicle flaps or skin grafting have been suggested for reconstruction of cervical scar contracture with variable results in the literature. The authors present the axial thoracic flap based on the thoracic branch of the supraclavicular artery (TBSA) for reconstruction of cervical scar contracture. Postburn scar contractures in anterior neck region of 66 patients had been reconstructed with the axial pattern thoracic flaps based on the TBSA, including 1 expanded and 10 nonexpanded pedicle flaps, and 9 expanded and 46 nonexpanded island pedicle flaps, during 1988 through 2012. After removing and releasing the cervical scar contracture, the flap was designed in the thoracic region. The axial artery of the flap is the TBSA bifurcating from the intersection point of sternocleidomastoid muscle and omohyoid muscle with several concomitant veins as the axial veins. The flap can be designed in a large area within the borders of the anterior border of the trapezius muscle superiorly, the middle part of the deltoid muscle laterally, the midsternal line medially, and the level 3 to 4 cm below nipples inferiorly. After incisions were made along the medial, inferior, and lateral border, dissection was performed toward the pedicle. Donor site was closed directly in expanded cases and with skin grafting in nonexpanded cases. Cervical scar contractures were repaired with good functional and cosmetic results in 64 cases among this cohort. Flap tip necrosis in other 2 cases, caused by postoperative hematoma, was repaired by skin grafting. The color and texture of all flaps were fitted with those of the surrounding skin. The donor sites all healed primarily. The flap sensation in the thoracic region regained in the early stage postoperatively and that in cervical area recovered completely after 6 months according to the report of the patients.

    Vascular thoracic outlet syndrome is caused by compression of subclavian/axillary vessels during their passage from the thoracic cavity to the axilla. Early diagnosis and treatment is important to prevent debilitating outcomes of vascular thoracic outlet syndrome. Contrast-enhanced three-dimensional (3D) magnetic resonance angiography (MRA) with equilibrium phase using provocative arm positioning is the optimal examination to determine presence, degree of vascular compression, and complications of vascular thoracic outlet syndrome. This article reviews thoracic outlet anatomy, disorders of the vascular component, and typical imaging findings by contrast-enhanced 3D MRA. Published by Elsevier Inc.

    mm polytetrafluoroethylene (e-PTFE mesh in nine cases of lateral or posterior defects. Support from a plastic surgeon was necessary to cover the full-thickness chest wall defects in seven cases. Adjuvant oncologic treatment was administered in 13 patients. Local recurrences were observed in five cases where surgical reintervention was finally necessary in two cases. Recurrences were associated with larger tumors, histology of malignant fibrous histiocytoma, and initial incomplete resection or misdiagnosis made by nonthoracic surgeons. Three patients died during the study period because of recurrent disease or complications of treatment for recurrent disease.Conclusion: Chest wall tumors are in their majority mesenchymal neoplasms, which often require major chest wall resection for their eradication. Long-term survival is expected in low-grade tumors where a radical resection is achieved, while big tumors and histology of malignant fibrous histiocytoma are connected with the increase rate of recurrence.Keywords: chest wall tumors, chest wall resection, chest wall reconstruction, soft tissue sarcomas, sternal tumors, chondrosarcoma

    To report and analyze noncardiac thoracic operations performed at the Cardiology Institute of Abidjan (Institut de Cardiologie d'Abidjan) from 1977 to 2015. This is a retrospective and descriptive study covering 39 years, from 1977 to 2015. This study period was divided into three periods of 13 years each: P1 from 1977 to 1989, P2 from 1990 to 2002 and P3 from 2003 to 2015. Medical records of 2014 operated patients were analyzed: 414 patients for P1, 464 patients for P2, 1,136 patients for P3. The records destroyed in a fire in 1997 were not included in the study. The age, sex, pathologies, types of operations, post-operative complications and mortality were analyzed with usual statistical tests. The average age varied from 35 years in P1 to 31.6 years in P3. Men predominate in all periods. Distribution of important groups of pathologies observed varies significantly over the three periods; In particular, we note an increase in trauma cases (tripling between P1 and P2, 140% between P2 and P3), and a decrease in tumors percentages, and infections and pulmonary sequelae of tuberculosis. Surgical management of thoracic trauma has increased (56.9% in P3) followed by the pleural surgery (21.3%) and pulmonary resections (13.9%). Persistent air leak >7 days was the predominant complication over the three periods. Postoperative empyema increased in P3 (14.7%). Close chest drainage-irrigation is the most frequent procedure performed to sterilize a major complication like postoperative empyema without bronchopleural fistula. Overall mortality decreased from 5.3% in P1 to 3.4% in P3. Noncardiac thoracic surgery operations still concern infections, pulmonary sequelae of tuberculosis, thoracic tumors and many more thoracic trauma caused by current armed conflicts and terrorist attacks. But access to thoracic surgical care remains difficult for our population secondary to low economic status, and lack of a health insurance system. Therefore surgical consultation is often

    Degenerative spondylolisthesis of the spine is less common in the lower thoracic region than in the lumbar and cervical regions. However, lower thoracic degenerative spondylolisthesis may develop secondary to intervertebral disc degeneration. Most of our patients are found to have concomitant lumbar spondylosis. By retrospective review of our cases, current diagnosis and treatments for this rare disease were discussed. We present a series of 5 patients who experienced low back pain, progressive numbness, weakness and even paraparesis. Initially, all of them were diagnosed with lumbar spondylosis at other clinics, and 1 patient had even received prior decompressive lumbar surgery. However, their symptoms continued to progress, even after conservative treatments or lumbar surgeries. These patients also showed wide-based gait, increased deep tendon reflex (DTR), and urinary difficulty. All these clinical presentations could not be explained solely by lumbar spondylosis. Thoracolumbar spinal magnetic resonance imaging (MRI), neurophysiologic studies such as motor evoked potential (MEP) or somatosensory evoked potential (SSEP), and dynamic thoracolumbar lateral radiography were performed, and a final diagnosis of lower thoracic degenerative spondylolisthesis was made. Bilateral facet effusions, shown by hyperintense signals in T2 MRI sequence, were observed in all patients. Neurophysiologic studies revealed conduction defect of either MEP or SSEP. One patient refused surgical management because of personal reasons. However, with the use of thoracolumbar orthosis, his symptoms/signs stabilized, although partial lower leg myelopathy was present. The other patients received surgical decompression in association with fixation/fusion procedures performed for managing the thoracolumbar lesions. Three patients became symptom-free, whereas in 1 patient, paralysis set in before the operation; this patient was able to walk with assistance 6 months after surgical decompression

    2016-12-01

    Osteomyelitis of the spine with associated spinal epidural abscess represents an uncommon entity in the pediatric population, requiring prompt evaluation and diagnosis to prevent neurological compromise. Cat scratch disease, caused by the pathogen Bartonella henselae, encompasses a wide spectrum of clinical presentations; however, an association with osteomyelitis and epidural abscess has been reported in only 4 other instances in the literature. The authors report a rare case of multifocal thoracic osteomyelitis with an epidural abscess in a patient with a biopsy-proven pathogen of cat scratch disease. A 5-year-old girl, who initially presented with vague constitutional symptoms, was diagnosed with cat scratch disease following biopsy of an inguinal lymph node. Despite appropriate antibiotics, she presented several weeks later with recurrent symptoms and back pain. Magnetic resonance imaging revealed 2 foci of osteomyelitis at T-8 and T-11 with an associated anterior epidural abscess from T-9 to T-12. Percutaneous image-guided vertebral biopsy revealed B. henselae by polymerase chain reaction analysis, and she was treated conservatively with doxycycline and rifampin with favorable clinical outcome.

    Three dogs were presented for investigation of recurrent pyrexia of unknown origin, chronic vomiting and respiratory distress, respectively. One dog was markedly underweight and the other two were cachexic. Physical examination and initial diagnostic tests failed to establish the underlying cause of the presenting signs. Thoracic radiographs were within normal limits for the age of the dog. In each case there was a high index of suspicion for an occult neoplastic process in view of the profound unexplained weight loss present. High-resolution computed tomography (HRCT) of the thorax was performed. The lung fields were divided into three zones for analysis and a novel classification scheme was used to describe the HRCT findings in each zone. Postmortem examination and histopathology confirmed the presence of an infiltrating metastatic carcinoma in all three cases. The HRCT changes correlated closely with the pathological findings. The authors conclude that HRCT of the lung should be considered for pulmonary metastatic screening in the dog and introduce a classification system for HRCT findings, based on terminology used in human medicine.

    Video-assisted thoracic surgery (VATS) has significantly developed over the last decade. However, a VATS approach for thymoma remains controversial. The aim of this study was to evaluate the feasibility of VATS thymectomy for the treatment of early-stage thymoma and to compare the outcomes with open resection. A comparative study of 59 patients who underwent surgical resection for early stage thymoma (VATS: 44 and open resection: 15) between 1993 and 2011 was performed. Data of patient characteristics, morbidity, mortality, length of hospital stay, the relationship between miasthenia gravis-thymoma, recurrence, and survival were collected for statistical analysis. Thymomas were classified according to Masaoka staging system: 38 in stage I (VATS group: 29 and open group: 9) and 21 in stage II (VATS group: 15 and open group: 6). The mean tumor size in the open group was 7.6cm (13-4cm) and in the VATS group 6.9cm (12-2.5cm). The average length of stay was shorter in the VATS group than in the open group (Pthymoma is technically feasible and is associated with a shorter hospital stay. The 5-year oncologic outcomes were similar in the open and VATS groups. Copyright © 2013 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.
