RESUMO

Cancer patients face many challenges that can have a significant impact on their quality of life (QOL). When patients experience multiple functional impairments due to disease or treatment, their QOL and the efficient use of healthcare resources can be compromised. This is particularly true for patients who are nearing the end of their lives, as the physical and emotional burden of cancer can have a profound effect on both the individual and their caregivers. One approach to improving QOL in these patients is through palliative rehabilitation. Despite being an underutilized and understudied resource, palliative rehabilitation has shown promise in helping patients with advanced cancer retain their dignity and sense of control. By maximizing functional independence and reducing symptom burdens, palliative rehabilitation can provide a vital source of support for patients and their caregivers during this challenging time. Inpatient rehabilitation is one way that palliative rehabilitation can be applied in a healthcare setting. While further research is needed to fully understand the benefits of this approach, it is clear that palliative rehabilitation has the potential to play a key role in helping patients and their caregivers navigate the challenges of cancer treatment and end-of-life care. This approach is specific to the USA context but can be applied in other settings where cancer patients require such care.

RESUMO

Objective: Lobar torsion is a rare occurrence in which a portion of the lung is twisted on its bronchovascular pedicle. The vast majority are observed in the acute postoperative period often following right upper lobectomy. Spontaneous middle lobe torsion independent of pulmonary resection is exceptionally rarer; fewer than 15 cases have been recorded. We present an institutional case series of 2 patients postorthotopic liver transplantation who developed spontaneous middle lobe torsion due to large pleural effusions. Methods: We provide the medical course as well as intraoperative techniques for our 2 patients along with a review of the literature. Results: Both patients in this case series underwent orthotopic liver transplant complicated postoperatively by a large pulmonary effusion. Patient one developed an abdominal hematoma requiring evacuation and repair, after which he developed progressive shortness of breath. Bronchoscopy revealed a right middle lobe obstruction; upon thoracotomy, 180-degree torsion with widespread necrosis was evident and the middle lobe was removed. He is doing well to date. Patient 2 experienced postoperative pleural effusion and mucus plugging; computed tomography revealed abrupt middle lobe arterial occlusion prompting urgent operative intervention. Again, the middle lobe was grossly ischemic and dissection revealed a 360-degree torsion around the pedicle. It was resected. He is doing well to date. Conclusions: As the result of its rarity, radiographic and clinical diagnosis of spontaneous pulmonary lobar torsion is challenging; a high index of suspicion for spontaneous middle lobe torsion must be maintained to avoid delays in diagnosis. Prompt surgical intervention is essential to improve patient outcomes.

RESUMO

In response to the 2010 earthquake and subsequent cholera epidemic, St Luke's Medical Center was established in Port-au-Prince, Haiti. Here, we describe its inception and evolution to include an intensive care unit and two operating rooms, as well as the staffing, training and experiential learning activities, which helped St Luke's become a sustainable surgical resource. We describe a three-phase model for establishing a sustainable surgical centre in Haiti (build facility and acquire equipment; train staff and perform surgeries; provide continued education and expansion including regular specialist trips) and we report a progressive increase in the number and complexity of cases performed by all-Haitian staff from 2012 to 2022. The results are generalised in the context of the 'delay framework' to global health along with a discussion of the application of this three-phase model to resource-limited environments. We conclude with a brief description of the formation of a remote surgical centre in Port-Salut, an unforeseen benefit of local competence and independence. Establishing sustainable and collaborative surgery centres operated by local staff accelerates the ability of resource-limited countries to meet high surgical burdens.

RESUMO

Usually used in emergency settings, bedside sonographic measurement of optic nerve sheath diameter can aid in diagnosing elevated intracranial pressure. We report a case of a 26-year-old male hospitalized for CAR T-cell therapy with Axicabtagene Ciloleucel for treatment of relapsed diffuse large B-cell lymphoma, who developed progressive symptoms of immune effector cell-associated neurotoxicity syndrome. Fundoscopic examination suggested the presence of blurred optic disc margins. Bedside ocular ultrasound revealed wide optic nerve sheath diameters and bulging optic discs bilaterally. The patient had a ventriculostomy placed for monitoring and received treatment with steroids and mannitol, as well as tocilizumab. After 7 days in the ICU, the patient recovered with no evidence of long-term neurological deficits.

RESUMO

BACKGROUND: Chimeric antigen receptor T-cell therapies (CAR-T) are transforming the treatment of B-cell leukemias and lymphomas. Cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome represent common, potentially life-threatening toxicities from chimeric antigen receptor T-cell therapy treatment. CASE SUMMARY: We present a 53-year-old patient with primary refractory high-grade B-cell lymphoma who developed severe, refractory neurotoxicity following chimeric antigen receptor T-cell therapy but exhibited complete recovery after extracorporeal blood purification with CytoSorb (CytoSorbents, Monmouth Junction, NJ).Six days after chimeric antigen receptor T-cell therapy infusion, the patient developed cytokine release syndrome grade 3, prompting administration of dexamethasone and tocilizumab, a monoclonal antibody against the interleukin-6 receptor. His C-reactive protein levels started to decrease with tocilizumab and dexamethasone treatments. However, his ferritin levels continued to rise, and his interleukin-6 levels were above the upper detection threshold. Thirty-six hours later, the patient showed improved cytokine release syndrome but developed severe immune effector cell-associated neurotoxicity syndrome with predominant encephalopathy (grade 3) despite treatment with dexamethasone/methylprednisolone, tocilizumab, and anakinra. We therefore sought a rescue strategy to remove inflammatory mediators. Following emergency use authorization, we initiated extracorporeal blood purification with CytoSorb (CytoSorbents).Four-day extracorporeal blood purification resulted in complete resolution of immune effector cell-associated neurotoxicity syndrome and greater than 95% reduction in interleukin-6 levels without side effects. The patient was discharged home 10 days later with no signs of neurotoxicity or other secondary end-organ dysfunction. CONCLUSIONS: Our case represents the first reported, successful application of extracorporeal blood purification with CytoSorb (CytoSorbents) to treat severe, refractory neurotoxicity following chimeric antigen receptor T-cell therapy.

RESUMO

Implantable chemoport is a very useful device for long-term venous access for infusion of chemotherapeutic drugs and other agents. There are few studies from resource poor countries reporting complications of chemoport. The aim of the present study is to evaluate the feasibility of chemoport insertion without image guidance and by closed technique without direct visualisation of a major vein (mainly IJV) and to study the complications associated with the procedure. This was a prospective observational study which analysed 263 patients who underwent chemoport insertion. The medical records of these patients were analysed for the patient characteristics, diagnosis, port-related complications, and their management. A total of 263 patients who were harbouring either locoregionally advanced or metastatic tumour requiring either chemotherapy or targeted treatment or both were included in the study. In total, 133 (50.57%) were female patients and 130 were male patients (49.43%). A total of 236 patients (89.73%) underwent port insertion procedures under local anaesthesia. None of the patients had any major intra-operative complications. Postoperatively, 4 patients (1.52%) were found to have port catheter malposition; 3 out of this 4 were corrected under IITV guidance as a second procedure under local anaesthesia only. One patient (0.38%) required formal removal and replacement of port. Four patients (1.52%) developed IJV thrombosis requiring port removal and anti-coagulation. One patient (0.38%) developed thrombus in the right atrium. There were 2 port site infections (0.74%) requiring port removal (SSI cat. 5). Low complication rates of port insertion were observed in the present, large, prospective study. Complication rates may be further reduced by using a well-designed procedure, experienced surgeons, an aseptic environment, ultrasound-guided puncture, and fluoroscopy with contrast media.

RESUMO

OBJECTIVE: While the surgical stages of single ventricle (SV) palliation serve to separate pulmonary venous and systemic venous return, and to volume-unload the SV, staged palliation also results in transition from parallel to series circulation, increasing total vascular resistance. How this transition affects pressure loading of the SV is as yet unreported. METHODS: We performed a retrospective chart review of Stage I, II, and III cardiac catheterization (CC) and echocardiographic data from 2001-2017 in all SV pts, with focus on systemic, pulmonary, and total vascular resistance (SVR, PVR, TVR respectively). Longitudinal analyses were performed with log-transformed variables. Effects of SVR-lowering medications were analyzed using Wilcoxon rank-sum testing. RESULTS: There were 372 total patients who underwent CC at a Stage I (median age of 4.4 months, n=310), Stage II (median age 2.7 years, n = 244), and Stage III (median age 7.3 years, n = 113). Total volume loading decreases with progression to Stage III (P< 0.001). While PVR gradually increases from Stage II to Stage III, and SVR increases from Stage I to Stage III, TVR dramatically increases with progress towards series circulation. TVR was not affected by use of systemic vasodilator therapy. TVR, PVR, SVR, and CI did not correlate with indices of SV function at Stage III. CONCLUSIONS: TVR steadily increases with an increasing contribution from SVR over progressive stages. TVR was not affected by systemic vasodilator agents. TVR did not correlate with echo-based indices of SV function. Further studies are needed to see if modulating TVR can improve exercise tolerance and outcomes.

RESUMO

OBJECTIVE: Peripherally inserted central catheters are a popular means of obtaining central venous access in critically ill patients. However, there is limited data regarding the rapidity of the peripherally inserted central catheter procedure in the presence of acute illness or obesity, both of which may impede central venous catheter placement. We aimed to determine the feasibility, safety, and duration of peripherally inserted central catheter placement in critically ill patients, including obese patients and patients in shock. METHODS: This retrospective cohort study was performed using data on 55 peripherally inserted central catheters placed in a 30-bed multidisciplinary intensive care unit in Mayo Clinic Hospital, Phoenix, Arizona. Information on the time required to complete each step of the peripherally inserted central catheter procedure, associated complications, and patient characteristics was obtained from a prospectively assembled internal quality assurance database created through random convenience sampling. RESULTS: The Median Procedure Time, beginning with the first needle puncture and ending when the procedure is complete, was 14 (interquartile range: 9-20) min. Neither critical illness nor obesity resulted in a statistically significant increase in the time required to complete the peripherally inserted central catheter procedure. Three (5.5%) minor complications were observed. CONCLUSION: Critical illness and obesity do not delay the acquisition of vascular access when placing a peripherally inserted central catheter. Concerns of delayed vascular access in critically ill patients should not deter a physician from selecting a peripherally inserted central catheter to provide vascular access when it would otherwise be appropriate.

RESUMO

PURPOSE: Whole-body computed tomography (CT) for blunt trauma patients is common. Chest CT (CCT) identifies "occult" pneumo- (PTX) and hemothorax (HTX) not seen on chest radiograph (CXR), one-third of whom get chest tubes, while CXR identifies "non-occult" PTX/HTX. To assess chest tube value for occult injury vs. expectant management, we compared output, duration, and length of stay (LOS) for chest tubes placed for occult vs. non-occult (CXR-visible) injury. METHODS: We compared chest tube output and duration, and patient length of stay for occult vs. non-occult PTX/HTX. This was a retrospective analysis of 5451 consecutive Level I blunt trauma patients, from 2010 to 2013. RESULTS: Of these blunt trauma patients, 402 patients (7.4%) had PTX, HTX or both, and both CXR and CCT. One third (n = 136, 33.8%) had chest tubes placed in 163 hemithoraces (27 bilateral). Non-occult chest tube output for all patients was 1558 ± 1919 cc (n = 54), similar to occult at 1123 ± 1076 cc (n = 109, p = 0.126). Outputs were similar for HTX-only patients, with non-occult (n = 34) at 1917 ± 2130 cc, vs. occult (n = 54) at 1449 ± 1131 cc (p = 0.24). Chest tube duration for all patients was 6.3 ± 4.9 days for non-occult vs. 5.0 ± 3.3 for occult (p = 0.096). LOS was similar between all occult injury patients (n = 46) and non-occult (n = 90, 17.0 ± 15.8 vs. 13.7 ± 11.9 days, p = 0.23). CONCLUSION: Mature clinical judgment may dictate which patients need chest tubes and explain the similarity between groups.

RESUMO

BACKGROUND: Despite an often severe lack of surgeons and surgical equipment, the rate-limiting step in surgical care for the nearly five billion people living in resource-limited areas is frequently the absence of safe anesthesia. During disaster relief and surgical missions, critical care physicians (CCPs), who are already competent in complex airway and ventilator management, can help address the need for skilled anesthetists in these settings. METHODS: We provided a descriptive analysis that CCPs were trained to provide safe general anesthesia, monitored anesthesia care (MAC), and spinal anesthesia using a specifically designed and simple syllabus. RESULTS: Six CCPs provided anesthesia under the supervision of a board-certified anesthesiologist for 58 (32%) cases of a total of 183 surgical cases performed by a surgical mission team at St. Luc Hospital in Port-au-Prince, Haiti in 2013, 2017, and 2018. There were no reported complications. CONCLUSIONS: Given CCPs' competencies in complex airway and ventilator management, a CCP, with minimal training from a simple syllabus, may be able to act as an anesthesiologist-extender and safely administer anesthesia in the austere environment, increasing the number of surgical cases that can be performed. Further studies are necessary to confirm our observation.

RESUMO

Male breast cancer is a rare tumour in all parts of the world. About 1% of all breast cancers occur in men. Occurrence of male breast cancer peaks at age 71 years. Familial cases usually have BRCA2 rather than BRCA1 mutations. Presentation is usually a lump or nipple inversion, but is often late, with more than 40% of individuals having stage III or IV disease. We retrospectively reviewed 25 male patients with breast cancer who came to the HCG Cancer Centre, Ahmedabad between 2014 and 2018, and their demographic details, tumor profile, and radiological, histopathological as well as luminal profile findings were studied. The average age at presentation and detection of male breast cancer was 61.08 years. Incidence of male ca. breast over these 4 years was 4.75/year which had a significant increase compared with our own data in the last 8 years (3/year). Male to female ratio for ca. breast was 1:61. One out of 25 (4%) patients had gynaecomastia. The most common histology was invasive ductal carcinoma-not otherwise specified with none of the patients having lobular carcinoma. Majority of patients were ER/PR positive and HER-2 negative. Male breast cancer is having a rising incidence, which in our study is 1.56%. Males have relatively older age at presentation and stage-by-stage treatment remains the same. Males are more likely to be having prognostically favourable luminal subtypes. Male breast cancer in Indian population is currently experiencing an increasing trend. Improved awareness amongst patients and high index of suspicion by the clinicians along with accurate diagnostic techniques help detect the disease at an earlier stage culminating into prolonged overall and disease-free survival.

RESUMO

Acetamide (CAS 60-35-5) is detected in common foods. Chronic rodent bioassays led to its classification as a group 2B possible human carcinogen due to the induction of liver tumors in rats. We used a toxicogenomics approach in Wistar rats gavaged daily for 7 or 28 days at doses of 300 to 1500 mg/kg/day (mkd) to determine a point of departure (POD) and investigate its mode of action (MoA). Ki67 labeling was increased at doses ≥750 mkd up to 3.3-fold representing the most sensitive apical endpoint. Differential gene expression analysis by RNA-Seq identified 1110 and 1814 differentially expressed genes in male and female rats, respectively, following 28 days of treatment. Down-regulated genes were associated with lipid metabolism while up-regulated genes included cell signaling, immune response, and cell cycle functions. Benchmark dose (BMD) modeling of the Ki67 labeling index determined the BMD10 lower confidence limit (BMDL10) as 190 mkd. Transcriptional BMD modeling revealed excellent concordance between transcriptional POD and apical endpoints. Collectively, these results indicate that acetamide is most likely acting through a mitogenic MoA, though specific key initiating molecular events could not be elucidated. A POD value of 190 mkd determined for cell proliferation is suggested for risk assessment purposes.

RESUMO

BACKGROUND: Bulbourethral syringocele is an uncommon and under-diagnosed condition most commonly seen in the paediatric population, although there is increasing recognition in adults. Due to the difficulty in diagnosis, we report our experience of urethral syringocele in a quaternary paediatric hospital, with differing presentations, diagnosis and treatment. METHODS: This is a retrospective review of seven cases of children over a period of 14 years, including their presentations, diagnosis, treatment and follow-up. A review of the current literature is presented. RESULTS: The median age of these seven cases at presentation was 11 years (6 days to 16 years). Clinical features varied with age, with obstructive uropathy in a neonate, urinary tract infection in an infant, scrotal abscess in two children and lower urinary tract obstructive symptoms in three teenagers. Diagnostic voiding cystogram diagnosed the majority of syringoceles and two were seen on magnetic resonance imaging. Five boys underwent endoscopic transurethral deroofing and two children required transperineal marsupialization. Long-term follow-up showed all had complete resolution of symptoms. CONCLUSION: Urethral syringocele presents from the neonatal period to late adolescence, with the presenting features reflective of age. Surgical management can be performed endoscopically or by open approach. Awareness of this condition and inclusion in the differential diagnosis, particularly in the setting of an atypical or recurrent scrotal abscess, could avoid a prolonged therapeutic course.

RESUMO

Despite improvements in overall graft function and patient survival rates after solid organ transplantation, complications can lead to significant morbidity and mortality. Cardiovascular complications include heart failure, arrhythmias leading to sudden death, hypertension, left ventricular hypertrophy, and allograft vasculopathy in heart transplantation. Neurologic complications include stroke, posterior reversible encephalopathy syndrome, infections, neuromuscular disease, seizure disorders, and neoplastic disease. Acute kidney injury occurs from immunosuppression with calcineurin inhibitors or as a result of graft failure after kidney transplantation. Gastrointestinal complications include infections, malignancy, mucosal ulceration, perforation, biliary tract disease, pancreatitis, and diverticular disease. Immunosuppression can predispose to infections and malignancy.

RESUMO

OBJECTIVE: To our knowledge, there is no study exploring specifically the diagnostic performance of diffusion-weighted imaging (DWI) in patients with previous canal wall down (CWD) surgery when combined with appropriate clinical evaluation. The aim of the present study was to evaluate the performance of DWI in the detection of residual or recurrent disease in patients who have had a previous CWD mastoidectomy. MATERIALS AND METHODS: We identified 13 patients with a CWD mastoidectomy subsequently having at least one further DWI prior to further mastoid exploration that generated a total of 20 patient episodes. Magnetic resonance imaging was performed on a 1.5 T superconductive unit using a standard head matrix coil. Coronal 2 mm thick TSE T2-weighted images (TR: 4640 ms; TE: 103 ms; matrix: 245,384; field of view: 150×200 mm) were performed. Operative findings were reviewed for all 20 patient episodes to compare DWI findings with intraoperative findings. Based on this, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated. RESULTS: DWI had a sensitivity of 93%, specificity of 60%, PPV of 87%, NPV of 75%, and accuracy of 80%. CONCLUSION: Given the high sensitivity of DWI in the detection of residual or recurrent disease, the present study supports DWI as a useful tool in the detection of residual or recurrent cholesteatoma in cases following CWD surgery, where clinical acumen suggests an ongoing disease process despite no overt cholesteatoma being visible.

RESUMO

BACKGROUND: Stapes surgery is performed for hearing restoration in patients with otosclerosis. Results from stapes surgery are good, although a small proportion will have a persistent conductive hearing loss and will consider revision surgery. The timing of such surgery depends on expected changes to hearing thresholds during the postoperative period. METHODS: We performed a retrospective case series analysis of a database of outcomes from stapes surgery performed between July 26, 2013 and March 11, 2016 at one center. Hearing outcomes over the year subsequent to surgery were recorded. RESULTS: There was a significant improvement in hearing outcomes between the postoperative visit at 6 weeks (mean air-bone gap 6.0 dB) and the hearing outcome at 6 months (mean air-bone gap 3.3 dB) (p < 0.01). This improvement was maintained at 12 months (mean air-bone gap 3.1 dB), although there were individual patients whose hearing outcome improved or deteriorated during this period. Improvements in air conduction thresholds mirrored improvements in air-bone gap measurements. CONCLUSION: Patients with an initial suboptimal or poor result after stapes surgery may observed improvement in their hearing thresholds in the year after surgery. These patients may have large preoperative air-bone gaps, and have a trend to have obliterated footplates. Revision surgery should not be considered until at least 6 months after primary surgery.

RESUMO

INTRODUCTION: Pre-operative evaluation of biliary strictures remains challenging. The dilemma that exists is how to balance the risk of failing to detect malignancy and the potential morbidity caused by unnecessary surgery in patients with benign etiologies. With emerging novel diagnostic modalities, this study aims to assess the efficacy of diagnostic techniques and facilitate a clinical approach to indeterminate biliary strictures. Areas covered: Conventional imaging modalities are crucial in identifying the location of a stricture and are helpful for choosing further diagnostic modalities. Utilization of endoscopic techniques, including endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS), is key in establishing a diagnosis. The emergence of novel diagnostic modalities, such as fluorescence in-situ hybridization (FISH), peroral cholangioscopy (POC), intraductal endoscopic ultrasound (IDUS) and confocal laser endomicroscopy (CLE), enhance the diagnostic yield in the evaluation of indeterminate biliary strictures. Expert commentary: More reliable and validated visual criteria for differentiating malignancy from benign biliary conditions, utilizing advanced imaging modalities such as POC and CLE, need to be established. It is of significance to further evaluate these novel diagnostic modalities through ongoing trials and to develop a diagnostic algorithm that reconciles cost-effectiveness with diagnostic accuracy.
