Increased airway hyperresponsiveness is a major concern in the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease. Guidelines using evidence-based medicine are continually being updated and published regarding the diagnosis, treatment, and prevention of these respiratory disorders. Perioperative management in these patients involves: (1) adequate control of airway hyperresponsiveness, including detection of purulent sputum and infection before surgery; (2) evidence-based control of anesthesia; and (3) the aggressive use of beta-2 adrenergic stimulants and the systemic administration of steroids for the treatment of acute attacks. Good preoperative control, including the use of leukotriene antagonists, can reduce the incidence of life-threatening perioperative complications. Awareness of recent guidelines is thus important in the management of patients with airway hyperresponsiveness. This review covers the most recent guidelines for the perioperative management of patients with bronchial asthma and chronic obstructive pulmonary disease.

Various surgical procedures have been described for the relief of chronic nasal obstruction due to inferior turbinate hypertrophy, but none has been consistently satisfactory. We have performed total inferior turbinectomy for this condition for 5 years. Of the 39 patients followed for at least 2 years, 90% were relieved permanently of nasal obstruction. However, only 36% and 61% of patients with rhinorrhoea and anosmia respectively were relieved of these symptoms. Complications were minimal. It is concluded that even in a dry, dusty tropical climate, inferior turbinectomy does not appear to disturb the function of the nasal cavity appreciably.

Introduction The terminal ileum is the most involved tract in Crohn’s disease. The obstruction in this location is the most frequent complication. Acute or chronic presentations can occur. Surgery finds a role in the management of chronic strictures and in acute clinical presentations with complications not improving with conservative therapy. Patients and methods We investigate the outcome of patients with obstruction of the ileo-cecal bowel tract laparoscopically managed. It was analyzed the average operative time (OT), the conversion rate and the occurrence of re-operation due to surgical complications. Results 21 patients underwent an ileocecal resection for complicated Crohn’s disease between January 2013 and December 2014. The admissions were performed in emergency in 42% of patients. The pre-intervention hospital stay was 5.8 (Sd 6.23). The mean operative time was 154 min (Sd 41). 28% of the procedures were converted to open surgery. The average hospital stay was 10 days (Sd 5) in uncomplicated patients. The morbidity rate was 28%. In 19% of cases a re-intervention was needed due to anastomotic leakage (3pts) and one hemoperitoneum for bleeding from the suture line. Discussion Laparoscopy seems an affordable technique in the management of obstructive pattern of Crohn’s disease. It should be the preferable approach in young patients that probably will be submitted to subsequent surgery for the same disease; in fact, the reduced adhesions formation provided by the less bowel manipulation make easy the subsequent access. Older patients had usually more post-operative morbidity and mortality mostly due to pre-existing conditions; if possible in these patients the treatment should be medical. PMID:28098059

2014-01-01

Chronic obstructive pulmonary disease (COPD) is a common and preventable lung disease that affects millions of people in the United States. Sleep disorders including obstructive sleep apnea (OSA) are also common. It is not surprising that many people with COPD also suffer from OSA. This relationship, however, puts people at risk for more nocturnal desaturations and potential complications related to this, including pulmonary hypertension and heart rhythm disturbances. This update focuses on the physiology of sleep disturbances in COPD as well as the clinical implications of OSA in COPD. PMID:24748786

Abstract Rationale: Xanthogranulomatous pyelonephritis (XGP) is a chronic destructive granulomatous inflammation that is characterized by urinary tract obstruction and invasion of the renal parenchyma. Although rare, XGP can lead to fatal complications, including perinephric inflammation, psoas abscess, and cutaneous fistula. Patient concerns: A quadriplegic patient initially presented to the hospital with a chronic open wound and cutaneous fistula. Diagnoses: Abdominal computed tomography revealed a renal obstructing stone and enlarged right kidney with a perinephric fluid collection that communicated with the cutaneous fistula. Interventions: The patient underwent a right nephrectomy at the department of urology. Outcomes: Two months after surgery, the patient was clinically well with no discharging fistula. Lessons: The XGP accompanied by complications requires an immediate evaluation and early diagnosis. In this case, the diagnosis was delayed because the state of quadriplegia rendered no symptoms of XGP. PMID:29480882

Pulmonary hypertension (PH) with complicating chronic lung diseases and/or hypoxia falls into group 3 of the updated classification of PH. Patients with chronic obstructive lung disease (COPD), diffuse lung disease (such as idiopathic pulmonary fibrosis (IPF)) and with sleep disordered breathing are particularly exposed to the risk of developing PH. Although PH in such a context is usually mild, a minority of patients exhibit severe haemodynamic impairment, defined by a mean pulmonary arterial pressure (mPAP) of ≥35 mmHg or mPAP values ranging between 25 mmHg and 35 mmHg with a low cardiac index (<2 L·min -1 ·m -2 ). The overlap between lung parenchymal disease and PH heavily affects life expectancy in such a patient population and complicates their therapeutic management. In this review we illustrate the pathological features and the underlying pathophysiological mechanisms of pulmonary circulation in chronic lung diseases, with an emphasis on COPD, IPF and obstructive sleep apnoea syndrome.

We report on two patients with recurrent episodes of chronic intestinal pseudo-obstruction (CIPO). A 50-year-old woman with severe multiple sclerosis and an 84-year-old man with Parkinson's disease and dementia had multiple hospital admissions because of pain and distended abdomen. Radiographic and endoscopic findings showed massive dilation of the colon without any evidence of obstruction. Conservative management resolved symptoms only for a short period of time. As these patients were poor candidates for any surgical treatment we carried out percutaneous endoscopic colostomy by placing a 20-Fr tube in the cecum with the introducer method. The procedure led to durable symptom relief without complications. We present these two cases and give a review through the existing literature of the procedure in CIPO. © 2015 Japan Gastroenterological Endoscopy Society.

The aim of this study was to review the various anesthetic options which can be considered for laparoscopic surgeries in the patients with the chronic obstructive pulmonary disease. The literature search was performed in the Google, PubMed, and Medscape using key words “analgesia, anesthesia, general, laparoscopy, lung diseases, obstructive.” More than thirty-five free full articles and books published from the year 1994 to 2014 were retrieved and studied. Retrospective data observed from various studies and case reports showed regional anesthesia (RA) to be valid and safer option in the patients who are not good candidates of general anesthesia like patients having obstructive pulmonary diseases. It showed better postoperative patient outcome with respect to safety, efficacy, postoperative pulmonary complications, and analgesia. So depending upon disease severity RA in various forms such as spinal anesthesia, paravertebral block, continuous epidural anesthesia, combined spinal epidural anesthesia (CSEA), and CSEA with bi-level positive airway pressure should be considered.

Inhaled corticosteroid (ICS) treatment has been shown to increase the risk of respiratory complications in patients with stable chronic obstructive pulmonary disease (COPD). However, the effects of perioperative ICS treatment on postoperative respiratory complications after lung cancer surgery have not been elucidated. The aim of this study was to investigate whether perioperative ICS treatment would increase the risk of postoperative respiratory complications after lung cancer surgery in patients with COPD. We retrospectively analyzed 174 consecutive COPD patients with non-small-cell lung cancer (NSCLC) who underwent lobectomy or segmentectomy between January 2007 and December 2014. Subjects were grouped based on whether or not they were administered perioperative ICS treatment. Postoperative cardiopulmonary complications were compared between the groups. There were no statistically significant differences in the incidence of postoperative respiratory complications (P = 0.573) between the perioperative ICS treatment group (n = 16) and the control group (n = 158). Perioperative ICS treatment was not significantly associated with postoperative respiratory complications in the univariate or multivariate analysis (odds ratio [OR] = 0.553, 95% confidence interval [CI] = 0.069-4.452, P = 0.578; OR = 0.635, 95% CI = 0.065-6.158, P = 0.695, respectively). Kaplan-Meier analysis showed that there were no statistically significant differences in the postoperative respiratory complications-free durations between the groups (P = 0.566), even after propensity score matching (P = 0.551). There was no relationship between perioperative ICS administration and the incidences of postoperative respiratory complications after surgical resection for NSCLC in COPD patients.

Update on endoscopic management of main pancreatic duct stones in chronic calcific pancreatitis.

2012-03-01

Pancreatic duct stones are a common complication during the natural course of chronic pancreatitis and often contribute to additional pain and pancreatitis. Abdominal pain, one of the major symptoms of chronic pancreatitis, is believed to be caused in part by obstruction of the pancreatic duct system (by stones or strictures) resulting in increasing intraductal pressure and parenchymal ischemia. Pancreatic stones can be managed by surgery, endoscopy, or extracorporeal shock wave lithotripsy. In this review, updated management of pancreatic duct stones is discussed.

Objectives Chronic obstructive pulmonary disease (COPD) is one of the main late complications of sulfur mustard poisoning. The aim of this study was to evaluate serum levels of interleukin (IL)-6 in war veterans with pulmonary complications of sulfur mustard poisoning and their correlation with severity of airways disease. Methods Fifty consecutive patients with sulfur mustard poisoning and stable COPD, and of mean age 46.3 ± 9.18 years were enrolled in this study. Thirty healthy men were selected as controls and matched to cases by age and body mass index. Spirometry, arterial blood gas, six- minute walk test, BODE (body mass index, obstruction, dyspnea, and exercise capacity), and St George’s Respiratory Questionnaire about quality of life were evaluated. Serum IL-6 was measured in both patient and control groups. Results Fifty-four percent of patients had moderate COPD. Mean serum IL-6 levels were 15.01 ± standard deviation (SD) 0.61 pg/dL and 4.59 ± 3.40 pg/dL in the case and control groups, respectively (P = 0.03). There was a significant correlation between IL-6 levels and Global Initiative for Chronic Obstructive Lung Disease stage (r = 0.25, P = 0.04) and between IL-6 and BODE index (r = 0.38, P = 0.01). There was also a significant negative correlation between serum IL-6 and forced expiratory volume in one second (FEV1, r = −0.36, P = 0.016). Conclusion Our findings suggest that serum IL-6 is increased in patients with sulfur mustard poisoning and COPD, and may have a direct association with airflow limitation. PMID:21037957

Although chronic obstructive pulmonary disease (COPD) is a common comorbidity in patients undergoing laryngeal cancer surgery, the impact of this comorbidity in this setting is not well established. In this analysis, we used the Nationwide Inpatient Sample (NIS) to elucidate the impact of COPD on outcomes after laryngectomy for laryngeal cancer. The NIS was queried for patients admitted from 1998 to 2010 with laryngeal cancer who underwent total or partial laryngectomy. Patient demographics, type of admission, length of stay, hospital charges, and concomitant diagnoses were analyzed. Our inclusion criteria yielded a cohort of 40,441 patients: 3,051 with COPD and 37,390 without. On average, COPD was associated with an additional $12,500 (P < 0.001) in hospital charges and an additional 1.4 days (P < 0.001) of hospital stay. There was no significant difference in incidence of in-hospital mortality between the COPD and non-COPD groups after total laryngectomy (1.1% in COPD vs. 1.0% in non-COPD; P = 0.776); however, there was an increased incidence of in-hospital mortality in the COPD group compared to the non-COPD group after partial laryngectomy (3.4% in COPD vs. 0.4% in non-COPD; P < 0.001). Multivariate adjusted logistic regression revealed that COPD was associated with greater odds of pulmonary complications after both partial laryngectomy (odds ratio [OR] = 3.198; P < 0.001) and total laryngectomy (OR = 1.575; P < 0.001). Chronic obstructive pulmonary disease appears to be associated with greater hospital charges, length of stay, and postoperative pulmonary complications in patients undergoing laryngectomy for laryngeal cancer. Chronic obstructive pulmonary disease after partial, but not total, laryngectomy appears to be associated with increased risk of in-hospital mortality. 2C.

Elephantiasis nostras verrucosa represents an infrequent clinical entity with cutaneous changes characterized by dermal fibrosis, hyperkeratotic verrucous and papillamotous lesions resulting from chronic non-filarial lymphedema secondary to infections, surgeries, tumor obstruction, radiation, congestive heart failure, and obesity. Although recurrent streptococcal lymphangitis is believed to play a critical role in the origin of elephantiasis nostras verrucosa, the exact pathogenesis of the disorder is not yet clear. Therapeutic efforts should aim to reduce lymph stasis, which will also lead to improvement of the cutaneous changes but unfortunately there is no specific treatment for advanced cases. In this report, we present a patient who was treated by below knee amputation as a result of elephantiasis nostras verrucosa complicated with chronic tibial osteomyelitis.

Sulfur mustard (SM) is a toxic chemical agent that belongs to a class of vesicant compounds. In the 1980s it was used by the Iraqi army against Iranian forces. Sulfur mustard severely irritates the skin, eyes and lungs. The highest side effects seen in patients affected by this gas are pulmonary complications including different types of lung diseases such as bronchiolitis. It has also led to a certain type of chronic obstructive pulmonary disease called mustard lung. Similar extra-pulmonary, molecular and hormonal effects can be observed in these patients and patients with chronic obstructive pulmonary disease. Here cardiovascular complications may be one of the most dangerous visible effects. And atherosclerosis is probable following the direct effects or consequential long-term effects of SM. The development of atherosclerosis in these patients is associated with an increased risk of cardiovascular and coronary artery disease. Coronary artery bypass grafting surgery is the treatment of coronary artery disease. Doing this surgery by bypass pump has its own morbidity and due to local and systemic inflammation changes in patients with SM pulmonary disorders it may have more side effects. Therefore, detailed knowledge of inflammatory diseases as well as the serum level or even the local lung fluid of the inflammatory factors in these patients before surgery are needed so that it would be possible to reduce the rate of morbidity and mortality by normalizing the inflammatory conditions of the patients before cardiac surgery.

Chronic Obstructive Pulmonary Disease: From Injury to Genomic Stability.

Chronic obstructive pulmonary disease (COPD) is the fourth cause of death in the world and it is currently presenting a major global public health challenge, causing premature death from pathophysiological complications and rising economic and social burdens. COPD develops from a combination of factors following exposure to pollutants and cigarette smoke, presenting a combination of both emphysema and chronic obstructive bronchitis, which causes lung airflow limitations that are not fully reversible by bronchodilators. Oxidative stress plays a key role in the maintenance and amplification of inflammation in tissue injury, and also induces DNA damages. Once the DNA molecule is damaged, enzymatic mechanisms act in order to repair the DNA molecule. These mechanisms are specific to repair of oxidative damages, such as nitrogen base modifications, or larger DNA damages, such as double-strand breaks. In addition, there is an enzymatic mechanism for the control of telomere length. All these mechanisms contribute to cell viability and homeostasis. Thus, therapies based on modulation of DNA repair and genomic stability could be effective in improving repair and recovery of lung tissue in patients with COPD.

In order to study the pathogenesis, clinical and pathological characteristics of proliferative lesions of the bladder, 50 cases of proliferative lesions of the bladder from 150 patients with complaints of frequency, urgency, hematuria and dysuria were subjected to cystoscopic biopsy of the suspicious foci in the bladder. In combination with the symptoms, urine and urodynamics, the relationship of proliferative lesions of the bladder to the inflammation and obstruction of the lower urinary tract was analyzed. Of the 50 cases of proliferative bladder lesions, 44 cases (88%) had lower urinary tract infection and 29 (58%) lower urinary tract obstruction. The patients with lower urinary tract obstruction were all complicated with infection. Three cases were associated with transitional cell carcinoma. Malignant cells were detected in 1 case by urinary cytologic examination. Proliferative lesions of the bladder, especially those without other obvious mucosa changes under cystoscopy, are common histological variants of urothelium in the patients with chronic inflammation and obstruction of the lower urinary tract. Chronic inflammation and obstruction of the lower urinary tract might be the causes for proliferative lesions of the bladder. It is suggested that different treatments should be applied according to the scope and histological type of the proliferative lesions.

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality and may frequently be complicated by sleep disorders. Insomnia and obstructive sleep apnea are commonly encountered in patients with COPD. Nocturnal hypoxemia is also prevalent in COPD may occur despite adequate awake oxygenation and can be especially severe in rapid eye movement sleep. Additionally, several factors—some of them unique to COPD—can contribute to sleep-related hypoventilation. Recognition of hypoventilation can be vital as supplemental oxygen therapy itself can acutely worsen hypoventilation and lead to disastrous consequences. Finally, accruing data establish an association between restless leg syndrome and COPD— an association that may be driven by hypoxemia and/or hypercapnia. Comorbid sleep disorders portend worse sleep quality, diminished quality of life, and multifarious other adverse consequences. The awareness and knowledge regarding sleep comorbidities in COPD has continued to evolve over past many years. There are still several lacunae, however, in our understanding of the etiologies, impact, and therapies of sleep disorders, specifically in patients with COPD. This review summarizes the latest concepts in prevalence, pathogenesis, diagnosis, and management of diverse sleep disorders in COPD. Citation: Budhiraja R, Siddiqi TA, Quan SF.

The paper presents the results of treatment in 30 patients aged 16-59 years who have bronchial asthma and chronic obstructive pulmonary disease, by using a bacterial vaccine (bronchomunal) containing antigens of opportunistic bacteria: Streptococcus pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae, Staphylococcus aureus, Streptococcus viridans, Streptococcus piogenes, Moraxella catarrhalis. Immunotherapy with the vaccine had good and excellent effects in 73.33 of cases; the mean duration of acute respiratory viral infection decreased from 16 to 9 days after vaccination and a need for antibiotics. In the comparison group, a good effect was noted in 40% of the patients during one-year follow-up; the difference was statistically significant. The vaccine's tolerance was good; only 3 (9.9%) patients were observed to have vaccination-induced complications: exacerbations of chronic maxillary sinusitis and chronic bronchitis in 2 and 1 patients, respectively. The positive effect of bronchomunal was associated with the better values of cellular immunity, stabilized phagocytosis, and lower IgE levels.

Chronic obstructive pulmonary disease: knowing what we mean, meaning what we say.

Joshi, J M

2008-01-01

Chronic obstructive pulmonary disease (COPD) is defined in several different ways using different criteria based on symptoms, physiological impairment and pathological abnormalities. While some use COPD to mean smoking related chronic airway disease, others include all disorders causing chronic airway obstruction. When COPD is used as a broad descriptive term, specific disorders that cause chronic airway obstruction remain under-diagnosed and the prevalence estimates vary considerably. The lack of agreement over the precise terminology and classification of COPD has resulted in widespread confusion. Terminology includes definition, diagnostic criteria, and a system for staging severity. Recently, COPD is defined more clearly and diagnosed using precise criteria that include tobacco smoking greater than 10 pack years, symptoms and airway obstruction on spirometry. A multi-dimensional severity grading system, the BODE (body mass index, obstruction, dyspnoea, and exercise tolerance) index has been designed to assess the respiratory and systemic expressions of COPD. This review proposes that the broad group of chronic disorders of the airways (with or without airway obstruction) be called chronic airway disease (CAD). The term COPD should be used exclusively for tobacco smoking related chronic airway disease. Chronic airway obstruction or obstructive lung disease may be used to define those conditions with airways obstruction caused by factors other than tobacco smoking. The aetiology may be appended to the label, for example, chronic airway obstruction/obstructive lung disease associated with bronchiectasis, chronic airway obstruction/obstructive lung disease associated with obliterative bronchiolitis or chronic airway obstruction/obstructive lung disease due to biomass fuel/occupational exposure.

Insertion of a self-expandable metal stent is still controversial for treatment of benign common bile duct stenosis but can be a valuable alternative to surgical treatment. Aim of our study was to analyze the efficacy of covered and uncovered self-expandable metal stent in patients with chronic pancreatitis and common bile duct stenosis. Twenty patients with common bile duct stenosis due to alcoholic chronic pancreatitis were retrospective analyzed. All patients had advanced chronic pancreatitis, presenting with calcifications in pancreatic head. Uncovered self-expandable metal stent (uSEMS) were used in 11 patients (3 females, 8 males) while in 9 patients (3 females, 6 males) partially covered self-expandable metal stent (cSEMS) were inserted. All patients treated with self-expandable metal stent had contraindications for surgery. Overall mean follow up time was 155 weeks: 206 (52-412) weeks in uSEMS, and 93 (25-233) weeks in cSEMS, respectively. Stent patency was in mean 118 weeks: 159 (44-412) weeks in uSEMS and 67 (25-150) weeks in cSEMS (P=0.019). In the uSEMS group, reintervention was necessary in 5 patients (45%) due to stent obstruction, whereas in the cSEMS group 4 patients (44%) needed reintervention (2 obstructions, 2 migration). Stent migration is an early complication, compared to obstruction (P<0.05), and in cSEMS obstruction occurred significantly earlier compared to uSEMS (P<0.05). Patency of uSEMS was significantly longer compared to partially cSEMS. Available self-expandable metal stent, unfortunately, do not meet the demands on successful treatment of benign common bile duct stenosis.

OBJECTIVE The authors conducted a survey to evaluate differences in the understanding and management of shunt-dependent hydrocephalus among members of the American Society of Pediatric Neurosurgeons (ASPN). METHODS Surveys were sent to all 204 active ASPN members in September 2014. One hundred thirty responses were received, representing a 64% response rate. Respondents were asked 13 multiple-choice and free-response questions regarding 4 fundamental problems encountered in shunted-hydrocephalus management: shunt malfunction, chronic cerebrospinal fluid (CSF) overdrainage, chronic headaches, and slit ventricle syndrome (SVS). RESULTS Respondents agreed that shunt malfunction occurs most often as the result of ventricular catheter obstruction. Despite contrary evidence in the literature, most respondents (66%) also believed that choroid plexus is the tissue most often found in obstructed proximal catheters. However, free-text responses revealed that the respondents' understanding of the underlying pathophysiology of shunt obstruction was highly variable and included growth, migration, or adherence of choroid plexus, CSF debris, catheter position, inflammatory processes, and CSF overdrainage. Most respondents considered chronic CSF overdrainage to be a rare complication of shunting in their practice and reported wide variation in treatment protocols. Moreover, despite a lack of evidence in the literature, most respondents attributed chronic headaches in shunt patients to medical reasons (for example, migraines, tension). Accordingly, most respondents managed headaches with reassurance and/or referral to pain clinics. Lastly, there were variable opinions on the etiology of slit ventricle syndrome (SVS), which included early shunting, chronic overdrainage, and/or loss of brain compliance. Beyond shunt revision, respondents reported divergent SVS treatment preferences. CONCLUSIONS The survey shows that there is wide variability in the understanding and management of shunt-dependent hydrocephalus and its complications. Such discrepancies appear to be derived partly from inconsistent familiarity with existing literature but especially from a paucity of high-quality publications.

We describe our laparoscopic longitudinal pancreaticojejunostomy (LPJ) technique using barbed sutures to manage a pancreatic duct obstruction. We performed laparoscopic longitudinal anterior pancreaticojejunostomy using barbed sutures (3-0 absorbable wound closure device, V-Loc, Covidien, Minneapolis, MN, USA) in 11 patients who presented with signs of a pancreas ductal obstruction and chronic pancreatitis. The surgical outcomes and follow-up records at the outpatient department were reviewed, and the effectiveness and feasibility of this method were analyzed. Mean patient age was 54.4 ± 9.5 years, and pancreatic duct stones were removed from all patients without conversion to laparotomy. Overall operative time was 200.7 ± 56.4 min, and estimated blood loss was 42.2 ± 11.2 ml. No pancreatic anastomosis leakage or postoperative bleeding was detected. Mean length of hospital stay was 6.5 ± 0.8 days, and mean time to start a soft diet was 4.8 ± 0.7 days. No patient complained of postoperative abdominal pain, and all patients recovered without significant complications or relapse of pancreatitis. The follow-up period was 4-21 months. Our new laparoscopic longitudinal anterior pancreaticojejunostomy technique (Puestow procedure) using barbed sutures is a potentially efficient and minimally invasive procedure for patients who suffer from pancreatic duct obstruction and chronic pancreatitis.

Achalasia is an idiopathic motility disorder of the oesophagus of increasing incidence. It is characterized by aperistalsis of the lower oesophagus and failure of relaxation of the lower oesophageal sphincter. Patients classically present with chronic symptoms of dysphagia, chest pain, weight loss and regurgitation, and they commonly suffer pulmonary complications such as recurrent microaspiration of static, retained food contents of the upper oesophagus. However, it has also been described, uncommonly, to present with megaoesophagus and secondary tracheal compression. We present a case of megaoesophagus secondary to achalasia which presented with stridor and signs of acute superior vena caval obstruction. PMID:26933001

Angioscopy Is Useful In The Evaluation Of Chronic Pulmonary Arterial Obstruction

We have previously described a fiberoptic angioscope for diagnostic use in the right heart and pulmonary arteries. The instrument has a 4 mm 0.D., a proximal flexion control lever, and a 0.8 mm inner channel used to inflate a polyurethane balloon attached to the distal end of the instrument. A conventional xenon light source provides illumination. The instrument is inserted through a right jugular venotomy and passed into the right heart and pulmonary arteries using direct vision and fluoroscopic guidance. The procedure has been performed in 4 patients with pulmonary hypertension suspected to be caused by chronic pulmonary emboli. Chronic emboli were found in two patients and central (resectable) emboli could be distinguished from peripheral ones. The third patient had normal pulmonary arterial intima and a final diagnosis of primary pulmonary hypertension was made. The fourth patient had extrinsic compression of pulmonary arteries by enlarged mediastinal nodes secondary to fibrosing mediastinitis. No complications occurred. We conclude that angioscopy appears to be useful in the diagnostic evaluation of patients with suspected chronic obstruction of the pulmonary arteries.

Non-obstructive prosthetic valve thrombosis is a rare and underestimated complication in patients with left-sided mechanical heart valves. Systemic embolisation, mainly involving the cerebral circulation, often represents the first clinical manifestation. We report a case of multiple, successive embolizations in the coronary and cerebral circulation, presenting with an acute myocardial infarction and stroke in a patient with latent, non-obstructive thrombosis of a mechanical bileaflet aortic valve. Because of scheduled urological surgery, chronic vitamin K antagonist treatment had previously been discontinued and replaced with low-molecular-weight heparin, at inadequate dosage. Following coronary arteriography, brain computed tomography scan and transoesophageal echocardiography, thrombolysis was performed successfully. This case emphasises the utility of performing transoesophageal echocardiography routinely in the presence of ischaemic signs in patients with mechanical heart valves. In patients requiring discontinuation of oral anticoagulant therapy, accurate management and continuous monitoring of alternative medications are needed in order to avoid severe thromboembolic complications.

Lung transplantation is an option in the treatment of end stage lung diseases, excluding lung cancer, that lead to short life expectancy and poor quality of life. Now they are mostly limited by shortage of donor organs and longterm complications. They are used for various lung diseases such as pulmonary vascular diseases, fibrosing diseases, chronic obstructive pulmonary diseases and diseases that cause chronic infections. Depending on the indication it is possible to perform heart and lung transplantation, single lung or double lung transplantation.Indications, contraindications, surgical methods, immunosuppression, complications and outcomes will be discussed. Survival is not as good as for other solid organ transplantation. Measurement of pulmonary function and quality of life improve with lung transplantation. Bronchiolitis obliterans is the most common complication and is the most limiting factor. A few Icelanders have undergone lung transplantation, most of them in Gothenburg, Sweden. The future of lung transplantation depends on limiting the incidence of bronchiolitis obliterans and finding more organ donors.

HIV-infected patients are at increased risk for development of pulmonary complications, including chronic obstructive pulmonary disease (COPD). Inflammation associated with sub-clinical infection has been postulated to promote COPD. Persistence of Pneumocystis (Pc) is associated with HIV and COPD, although a causal relationship has not been established. We used a simian/human immunodeficiency virus (SHIV) model of HIV infection to study pulmonary effects of Pc colonization. SHIV-infected/Pc-colonized monkeys developed progressive obstructive pulmonary disease characterized by increased emphysematous tissue and bronchial-associated lymphoid tissue. Elevated Th2 cytokines and pro-inflammatory mediators in bronchoalveolar lavage fluid coincided with Pc colonization and pulmonary function decline. These results support the concept that an infectious agent contributes to development of HIV-associated lung disease and suggests that Pc colonization may be a risk factor for the development of HIV-associated COPD. Furthermore, this model allows examination of early host responses important to disease progression thus identifying potential therapeutic targets for COPD. PMID:20533880

Other than trauma, rib fracture can occur spontaneously due to a severe cough or sneeze. In this study, patients with spontaneous rib fractures were analyzed according to age, sex, underlying pathology, treatment, and complications. Twelve patients who presented between February 2009 and February 2011 with spontaneous rib fracture were reviewed retrospectively. The patients' data were evaluated according to anamnesis, physical examination, and chest radiographs. The ages of the patients ranged from 34 to 77 years (mean 55.91 ± 12.20 years), and 7 (58.4%) were male. All patients had severe cough and chest pain. The fractures were most frequently between 4th and 9th ribs; multiple rib fractures were detected in 5 (41.7%) patients. Eight (66.7%) patients had chronic obstructive pulmonary disease, 2 (16.7%) had bronchial asthma, and 2 (16.7%) had osteoporosis. Bone densitometry revealed a high risk of bone fracture in all patients. Patients with chronic obstructive pulmonary disease or bronchial asthma had been treated with high-dose steroids for over a year. Spontaneous rib fracture due to severe cough may occur in patients with osteoporosis, chronic obstructive pulmonary disease, or bronchial asthma, receiving long-term steroid therapy. If these patients have severe chest pain, chest radiography should be performed to check for bone lesions. © The Author(s) 2015.

Inspissated oral secretions and a review of their clinical, biological, and physiological significance.

PubMed

Flanagan, Dennis

2012-06-01

People with some chronic diseases may dehydrate and develop thick, viscous inspissated oronasal secretions that include cellular debris. This material can lead to ductal or airway obstructions that can prove to be life threatening. Asthma, allergy with superinfection, cystic fibrosis, intubated ventilation, burn injuries, and medication-induced complications are discussed in this paper. Many patients with chronic debilitating conditions may also be unable to communicate, and so may be unable to verbally convey that they have a compromised airway or an obstruction. Therefore, it is essential to maintain hydration and good oral hygiene that not only addresses the teeth and prostheses, but also the oral mucosal surfaces. People who are institutionalized and bed-ridden, in particular, need to be closely monitored to prevent adverse sequellae. A daily oral sweep with a 4 × 4 surgical sponge moistened with chlorhexidine may prevent aspiration pneumonia or a fatality due to an airway obstruction. Human oronasal secretions are involved with immunity, digestion, lubrication, and speech. Saliva is the most volumetrically important. These secretions moisturize inspired and expired air but can lose water, causing an increase in viscosity. The viscous secretions trap particles, food debris, and bacterial colonies, thereby increasing inspissations that may obstruct the airway. © 2012 Special Care Dentistry Association and Wiley Periodicals, Inc.

Pulmonary arterial hypertension (PAH) is a complication of chronic obstructive pulmonary disease (COPD) in advance stages, and its presence indicates poor prognosis. The present study was design to know the prevalence of PAH in patients with COPD and its correlation with stages of COPD, exercising capacity, and quality of life. It is a cross-sectional prevalence study over a period of 1 year from August 2015 to July 2016. The study included 109 COPD patients, diagnosed by spirometry, and severity was determined according Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification criteria. Screening two-dimensional echocardiography was done to determine pulmonary arterial hypertension and exercising capacity assessed by 6 min walk test (6MWT) while the quality of life was assessed by St George respiratory Questionnaire for COPD (SGRQ-C) Questionnaires. Out of 109 patients, PAH was present in 68 (62.4%) cases consisting of mild grade 41 (37.6%), moderate grade 11 (10.1%), and severe grade 16 (14.7%). In GOLD A stage, there were 20 cases of mild PAH and Stage B included 18 cases of mild and 3 cases of moderate PAH. Stage C had 3 cases of mild and 8 cases of moderate PAH while Stage D had 16 cases of severe PAH. In 6MWT, patients with severe grade PAH fail to perform the test while patients with mild to moderate PAH walked short distance. In SGRQ-C Questionnaires symptom, activity, impact, and total score were high with the severity of PAH. The prevalence of PAH in COPD was significant. Therefore, every COPD patient should be evaluated for PAH.

Ventriculoperitoneal (VP) shunt insertion is one of the most common neurosurgical procedures for the treatment of chronic hydrocephalus. Although regarded as a relatively benign procedure, several complications including obstruction, infection and mechanical failure can be seen during the postoperative stage. Symptomatic sterile cerebrospinal fluid (CSF) ascites and hydrothoracies are rare complications of VP shunt surgery. The paucity of cases makes identifying the aetiological factors difficult, particularly without catheter tip migration. It is most likely that several factors interact to reduce the absorption of CSF. The authors discuss the case of a 5-year-old girl who developed CSF ascites and a pleural effusion after starting chemotherapy for a suprasellar pilocytic astrocytoma, 2 years post-VP shunt insertion, due to a secondary obstructive hydrocephalus. After the initial management of the presenting symptoms, the child's VP shunt was subsequently changed to a ventriculo-atrial shunt and the patient made an unremarkable recovery. We also review the literature pertaining to this rare complication, assessing identifiable risk factors and surgical management options. PMID:23396932

In this perspective-based article, which is based on findings from a comprehensive literature search, we discuss the significant and growing burden of chronic obstructive pulmonary disease in women worldwide. Chronic obstructive pulmonary disease now affects both men and women almost equally. Despite this, there remains an outdated perception of chronic obstructive pulmonary disease as a male-dominated disease. Primary care physicians play a central role in overseeing the multidisciplinary care of women with chronic obstructive pulmonary disease. Many women with chronic obstructive pulmonary disease delay seeking medical assistance, due to fear of stigmatization or dismissing symptoms as a 'smoker's cough'. Improving awareness is important to encourage women with symptoms to seek advice earlier. Once women do seek help, primary care physicians need to have knowledge of the nuances of female chronic obstructive pulmonary disease disease presentation to avoid mis- or delayed diagnosis, both of which are more common in women with chronic obstructive pulmonary disease than men. Subsequent management should consider gender-specific issues, such as differential incidences of comorbid conditions, potentially higher symptom burden, and a higher risk of exacerbations. Chronic obstructive pulmonary disease treatment and smoking cessation management should be specifically tailored to the individual woman and reviewed regularly to optimize patient outcomes. Finally, education should be an integral part of managing chronic obstructive pulmonary disease in women as it will help to empower them to take control of their disease.

[Anaesthesia for patients with obstructive airway diseases].

Obstructive lung diseases like asthma or chronic obstructive lung diseases have a high prevalence and are one of the four most frequent causes of death. Obstructive lung diseases can be significantly influenced by the choice of anesthetic techniques and anesthetic agents. Basically, the severity of the COPD and the degree of bronchial hyperreactivity will determine the perioperative anesthetic risk. This risk has to be assessed by a thorough preoperative evaluation and will give the rationale on which to decide for the adequate anaesthetic technique. In particular, airway instrumentation can cause severe reflex bronchoconstriction. The use of regional anaesthesia alone or in combination with general anaesthesia can help to avoid airway irritation and leads to reduced postoperative complications. Prophylactic antiobstructive treatment, volatile anesthetics, propofol, opioids, and an adequate choice of muscle relaxants minimize the anesthetic risk, when general anesthesia is required In case, despite all precautions intra-operative bronchospasm occurs, deepening of anaesthesia, repeated administration of beta2-adrenergic agents and parasympatholytics, and a single systemic dose of corticosteroids represent the main treatment options.

The Frey procedure has become the standard operative treatment in chronic painful pancreatitis. Biliary diversion could be combined when associated with common bile duct obstruction. The aim of the present study was to evaluate the impact of the type of biliary diversion combined with the Frey procedure on late morbidity. The data from consecutive patients undergoing the Frey procedure and having a minimum follow-up of 2 years were extracted from a maintained prospective database. The mean endpoint was the rate of secondary biliary stricture after the Frey procedure combined with biliary diversion (bilioenteric anastomosis or common bile duct reinsertion in the resection cavity). Between 2006 and 2013, 55 consecutive patients underwent the Frey procedure. Twenty-nine patients had common bile duct obstruction (52.7%). The technique of biliary diversion resulted in bilioenteric anastomosis in 19 patients (65.5%) and common bile duct reinsertion in 10 patients (34.5%). Preoperative characteristics and early surgical outcomes were comparable. Pain control was similar. There was significantly more secondary biliary stricture after common bile duct reinsertion than after bilioenteric anastomosis (60% vs 11%, P = .008). Combined bilioenteric anastomosis during the Frey procedure is an efficient technique for treating common bile duct obstruction that complicates chronic painful pancreatitis. Bilioenteric anastomosis was associated with less secondary biliary stricture than common bile duct reinsertion in the pancreatic resection cavity. Copyright © 2016 Elsevier Inc.

Many conditions such as bacterial and viral infectious diseases, mechanical obstruction due to air and calculi and drugs can cause parotitis. We present a case of unusual bilateral parotitis in a patient under non-invasive continuous positive airway pressure (CPAP) therapy for chronic obstructive pulmonary disease exacerbation in intensive care unit. A 36-year-old patient was admitted to intensive care unit with the diagnosis of chronic obstructive pulmonary disease exacerbation. Antibiotherapy, bronchodilator therapy and non-invasive positive pressure ventilation were applied as treatment regimen. Painless swellings developed on the 3rd day of admission on the right and a day after this on the left parotid glands. Amylase levels were increased and ultrasonographic evaluation revealed bilateral parotitis. No intervention was made and the therapy was continued. The patient was discharged on the 6th day with clinical improvement and regression of parotid swellings without any complications. Parotitis may have occurred after retrograde air flow in the Stensen duct during CPAP application. After the exclusion of possible viral and bacteriological etiologies and possible drug reactions we can focus on this diagnosis. Copyright © 2014 Sociedade Brasileira de Anestesiologia.

Achalasia is an idiopathic motility disorder of the oesophagus of increasing incidence. It is characterized by aperistalsis of the lower oesophagus and failure of relaxation of the lower oesophageal sphincter. Patients classically present with chronic symptoms of dysphagia, chest pain, weight loss and regurgitation, and they commonly suffer pulmonary complications such as recurrent microaspiration of static, retained food contents of the upper oesophagus. However, it has also been described, uncommonly, to present with megaoesophagus and secondary tracheal compression. We present a case of megaoesophagus secondary to achalasia which presented with stridor and signs of acute superior vena caval obstruction.

Objective Emerging research suggests that aerobic-based physical activity may help to promote survival among chronic obstructive pulmonary disease patients. However, the extent to which engagement in resistance training on survival among chronic obstructive pulmonary disease patients is relatively unknown. Therefore, the purpose of this study was to examine the independent associations of muscle strengthening activities on all-cause mortality among a national sample of U.S. adults with chronic obstructive pulmonary disease. We hypothesize that muscle strengthening activities will be inversely associated with all-cause mortality. Methods Data from the 2003-2006 NHANES were employed, with follow-up through 2011. Aerobic-based physical activity was objectively measured via accelerometry, muscle strengthening activities engagement was assessed via self-report, and chronic obstructive pulmonary disease was assessed via physician-diagnosis. Results Analysis included 385 adults (20 + yrs) with chronic obstructive pulmonary disease, who represent 13.3 million chronic obstructive pulmonary disease patients in the USA. The median follow-up period was 78 months (IQR=64-90), with 82 chronic obstructive pulmonary disease patients dying during this period. For a two muscle strengthening activity sessions/week increase (consistent with national guidelines), chronic obstructive pulmonary disease patients had a 29% reduced risk of all-cause mortality (HR=0.71; 95% CI: 0.51-0.99; P = 0.04). Conclusion Participation in muscle strengthening activities, independent of aerobic-based physical activity and other potential confounders, is associated with greater survival among chronic obstructive pulmonary disease patients.

Recent work has suggested that within-breath respiratory impedance measurements performed using the forced oscillation technique may help to noninvasively evaluate respiratory mechanics. We investigated the influence of airway obstruction on the within-breath forced oscillation technique in smokers and chronic obstructive pulmonary disease patients and evaluated the contribution of this analysis to the diagnosis of chronic obstructive pulmonary disease. Twenty healthy individuals and 20 smokers were assessed. The study also included 74 patients with stable chronic obstructive pulmonary disease. We evaluated the mean respiratory impedance (Zm) as well as values for the inspiration (Zi) and expiration cycles (Ze) at the beginning of inspiration (Zbi) and expiration (Zbe), respectively. The peak-to-peak impedance (Zpp=Zbe-Zbi) and the respiratory cycle dependence (ΔZrs=Ze-Zi) were also analyzed. The diagnostic utility was evaluated by investigating the sensitivity, the specificity and the area under the receiver operating characteristic curve. ClinicalTrials.gov: NCT01888705. Airway obstruction increased the within-breath respiratory impedance parameters that were significantly correlated with the spirometric indices of airway obstruction (R=-0.65, p<0.0001). In contrast to the control subjects and the smokers, the chronic obstructive pulmonary disease patients presented significant expiratory-inspiratory differences (p<0.002). The adverse effects of moderate airway obstruction were detected based on the Zpp with an accuracy of 83%. Additionally, abnormal effects in severe and very severe patients were detected based on the Zm, Zi, Ze, Zbe, Zpp and ΔZrs with a high degree of accuracy (>90%). We conclude the following: (1) chronic obstructive pulmonary disease introduces higher respiratory cycle dependence, (2) this increase is proportional to airway obstruction, and (3) the within-breath forced oscillation technique may provide novel parameters that facilitate the diagnosis of respiratory abnormalities in chronic obstructive pulmonary disease.

What Is the Prevalence of Symptomatic Obstructive Sleep Apnea Syndrome in Chronic Spinal Pain Patients? An Assessment of the Correlation of OSAS with Chronic Opioid Therapy, Obesity, and Smoking.

In modern medicine, obstructive sleep apnea syndrome (OSAS) is a commonly described sleep disorder with airway obstruction, disrupted sleep, and excessive daytime sleepiness. Since its description in 1976 by Guilleminault et al, numerous epidemiologic studies and systematic reviews, with multiple comorbidities related to cardiovascular sequelae, altered cognitive function, and multiple other potential complications have been described. Multiple risk factors have been identified included obesity, smoking, alcohol consumption, and other factors. Chronic pain and chronic opioid therapy also have been described to contribute to a large proportion of patients with OSAS. Chronic pain, obesity, smoking, and chronic opioid therapy are often found together, yet there is a paucity of literature describing OSAS in chronic pain patients. To assess the prevalence of symptomatic OSAS in chronic spinal pain patients receiving chronic opioid therapy and determine the association of OSAS with multiple risk factors and comorbidities. A retrospective assessment of patients who attend a single interventional pain management practice from January 1, 2010to December 31, 2014. A private interventional pain management practice in the United States. The data were collected from 4,036 consecutive patients presenting for assessment to a pain management center from January 1, 2010 to December 31, 2014. All assessments were comprehensive and performed by 2 physicians. The comprehensive assessment included a complete history, a physical examination, and a review of records. The prevalence of OSAS in patients with chronic spinal pain was 13.8%. The results showed a higher prevalence in males compared to females (15.1% versus 12.8%), a higher prevalence in those aged 45 or older compared to those 25-45 years and those 18-25 years (16.3% versus 10.7% or 2.5%), higher prevalence in Hispanics and Asians compared to African Americans and whites (23.7% versus 16.2% versus 13.4%), higher prevalence in patients with combined back and neck pain compared to patients with thoracic pain only or back pain only (16.3% versus 8.2% to 11%). Prevalence also varied by body mass index (BMI): 32.4% in morbidly obese patients, 20.3% in severely obese patients, 15.7% in obese patients, 9.2% in those who were overweight, and only 5.7% in those with normal weight. A significant correlation with OSAS was also observed in patients smoking more than 40 pack years and multiple respiratory symptoms except for chronic bronchitis and multiple cardiovascular ailments. The retrospective nature of the assessment. This retrospective assessment of over 4,000 patients suffering from chronic pain and receiving chronic opioid therapy indicated a prevalence of sleep apnea syndrome as 13.8%. Multiple risk factors including obesity, chronic obstructive pulmonary disease (COPD), chronic sinus and nasal discharge, and multiple comorbidities including cardiovascular and related ailments have been identified.

Given the extent of the surgical indications for pulmonary lobectomy in breathless patients, preoperative care and evaluation of pulmonary function are increasingly necessary. The aim of this study was to assess the contribution of preoperative pulmonary rehabilitation (PR) for reducing the incidence of postoperative pulmonary complications in non-small cell lung cancer (NSCLC) patients with chronic obstructive pulmonary disease (COPD). The records of 116 patients with COPD, including 51 patients who received PR, were retrospectively analyzed. Pulmonary function testing, including slow vital capacity (VC) and forced expiratory volume in one second (FEV 1 ), was obtained preoperatively, after PR, and at one and six months postoperatively. The recovery rate of postoperative pulmonary function was standardized for functional loss associated with the different resected lung volumes. Propensity score analysis generated matched pairs of 31 patients divided into PR and non-PR groups. The PR period was 18.7 ± 12.7 days in COPD patients. Preoperative pulmonary function was significantly improved after PR (VC 5.3%, FEV 1 5.5%; P < 0.05). The FEV 1 recovery rate one month after surgery was significantly better in the PR (101.6%; P < 0.001) than in the non-PR group (93.9%). In logistic regression analysis, predicted postoperative FEV 1 , predicted postoperative %FEV 1 , and PR were independent factors related to postoperative pulmonary complications after pulmonary lobectomy (odds ratio 18.9, 16.1, and 13.9, respectively; P < 0.05). PR improved the recovery rate of pulmonary function after lobectomy in the early period, and may decrease postoperative pulmonary complications. © 2017 The Authors.

To describe and compare nutritional status, pulmonary function, gender and marital status in patients with chronic obstructive pulmonary disease. Chronic obstructive pulmonary disease is a chronic illness that can lead to poor nutritional status due to an increased energy requirements related to laboured breathing. Inadequate nutritional intake has often been described in this patient group. Nutritional support for patients with chronic obstructive pulmonary disease who suffer from nutritional problems is essential, both for their sense of well-being and for their survival with chronic obstructive pulmonary disease. The study design was descriptive and comparative. Quantitative data collection was carried out among 81 patients with chronic obstructive pulmonary disease (47 women and 34 men) with an average age of 65 years (SD 3·5). The Mini Nutritional Assessment was used to assess nutritional status. Participants who lived alone had worse nutritional status than those who did not live alone, and female participants had worse nutritional status than their male counterparts. No significant correlation was found between pulmonary function and nutritional status. This study contributes knowledge of a potential correlation between nutritional status, gender and marital status in patients with chronic obstructive pulmonary disease. Women with chronic obstructive pulmonary disease may be at an increased risk of malnutrition. Despite the previous results showing malnutrition and underweight to be common, the present study found that many of the participants were overweight, which may reflect a global health trend regardless of disease. Early identification of patients at risk of malnutrition is important. Registered nurses should be aware that patients with chronic obstructive pulmonary disease who are female or who live alone may be at an increased risk of nutritional problems. Patients with chronic obstructive pulmonary disease must be offered information and support for individually adapted measures at an early stage in order to avoid nutritional problems, regardless of under- and overweight. © 2013 John Wiley & Sons Ltd.

The natural history of cystic fibrosis (CF) may be associated both with acute respiratory complications (respiratory exacerbations, haemoptysis, pneumothorax) and with non-respiratory complications (distal intestinal obstruction syndrome, dehydration) that may result in hospitalizations. The aim of this article is to describe the main therapeutic approaches that are adopted in the management of acute complications occurring in CF adults, and to discuss indications for admission of these patients to intensive care units. Adult CF patients admitted to intensive care unit often benefit from antibiotic courses adapted to their chronic bronchial infection, especially when the hospitalization is related to respiratory disease (including haemoptysis and pneumothorax). Nutritional support, including hypercaloric diet, control of hyperglycemia and pancreatic enzyme supplementation is warranted. The recommended therapy for major haemoptysis is bronchial artery embolization. Patient with significant pneumothorax should have a chest tube inserted, while the treatment of distal intestinal obstruction syndrome will most often be medical. In case of respiratory failure, non-invasive ventilation is the preferred mode of ventilatory support because invasive ventilation is associated with poor outcomes. Therapeutic options should always have been discussed between the patient, family members and the CF medical team to allow for informed decision making. Copyright © 2011 SPLF.

Secondary pulmonary lymphangiectasia is a complication of congenital heart disease that results from chronic pulmonary venous obstruction. We aimed to evaluate the performance of chest ultrasound (US) in diagnosing secondary pulmonary lymphangiectasia and to review the clinical course of children with secondary pulmonary lymphangiectasia. Chest US was performed on 26 children with hypoplastic left heart syndrome, total anomalous pulmonary venous connection or cor triatriatum in a prospective observational study. Thirteen children had pulmonary venous obstruction (62% male; median age: 17 days old, range: 1-430 days old) and 13 children did not have obstruction (62% male; median age: 72 days old, range: 4-333 days old). US features of secondary pulmonary lymphangiectasia were documented and diagnostic performance was determined. Clinical course of patients with secondary pulmonary lymphangiectasia was reviewed. Eleven of 13 (84.6%) patients in the obstructed group had a clinical and/or biopsy diagnosis of secondary pulmonary lymphangiectasia. Statistically significant chest US criteria for diagnosis were presence of irregular lung surface (likelihood ratio [LR] 6.8, 95% confidence interval [CI] 1.9-25.1), subpleural cystic appearing structures (LR 3.6, 95% CI 1.2-10.7), and combination of subpleural cystic appearing structures and surface irregularity together (LR 10.9, 95% CI 1.6-75.0). Seven of 11 (63.6%) patients with secondary pulmonary lymphangiectasia died during follow-up, the majority due to cardiopulmonary failure or complications. Chest US is an accurate and reproducible bedside method for diagnosing secondary pulmonary lymphangiectasia in patients with pulmonary venous obstruction. These patients may have worse prognoses.

Chronic obstructive pulmonary disease is the fourth leading cause of mortality worldwide. It is defined as a persistent airflow limitation usually progressive and not fully reversible to treatment. The diagnosis of chronic obstructive pulmonary disease and severity of disease is confirmed by spirometry. Chronic obstructive pulmonary disease produces electrical changes in the heart which shows characteristic electrocardiogram pattern. The aim of this study was to observe and evaluate diagnostic values of electrocardiogram changes in chronic obstructive pulmonary disease patients with no other comorbidity. We analyzed 110 electrocardiogram findings in clinically stable chronic obstructive pulmonary disease patients and evaluated the forced expiratory volume in the first second, ratio of forces expiratory volume in the first second to the fixed vital capacity, chest radiographs and electrocardiogram changes such as p wave height, QRS axis and voltage, right bundle branch block, left bundle branch block, right ventricular hypertrophy, T wave inversion in leads V1-V3, S1S2S3 syndrome, transition zone in praecordial lead and QT interval. We found electrocardiogram changes in 64% patients, while 36% had normal electrocardiogram. The most frequent electrocardiogram changes observed were transition zone (76.36%) low QRS (50%) and p pulmonale (14.54%). Left axis deviation was observed in 27.27% patients. Diagnostic values of electrocardiogram in patients with chronic obstructive pulmonary disease suggest that chronic obstructive pulmonary disease patients should be screened electrocardiographically in addition to other clinical investigations.

Executive Summary In July 2010, the Medical Advisory Secretariat (MAS) began work on a Chronic Obstructive Pulmonary Disease (COPD) evidentiary framework, an evidence-based review of the literature surrounding treatment strategies for patients with COPD. This project emerged from a request by the Health System Strategy Division of the Ministry of Health and Long-Term Care that MAS provide them with an evidentiary platform on the effectiveness and cost-effectiveness of COPD interventions. After an initial review of health technology assessments and systematic reviews of COPD literature, and consultation with experts, MAS identified the following topics for analysis: vaccinations (influenza and pneumococcal), smoking cessation, multidisciplinary care, pulmonary rehabilitation, long-term oxygen therapy, noninvasive positive pressure ventilation for acute and chronic respiratory failure, hospital-at-home for acute exacerbations of COPD, and telehealth (including telemonitoring and telephone support). Evidence-based analyses were prepared for each of these topics. For each technology, an economic analysis was also completed where appropriate. In addition, a review of the qualitative literature on patient, caregiver, and provider perspectives on living and dying with COPD was conducted, as were reviews of the qualitative literature on each of the technologies included in these analyses. The Chronic Obstructive Pulmonary Disease Mega-Analysis series is made up of the following reports, which can be publicly accessed at the MAS website at: http://www.hqontario.ca/en/mas/mas_ohtas_mn.html.

Background Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation throughout the airways, parenchyma, and pulmonary vasculature. The inflammation causes repeated cycles of injury and repair in the airway wall— inflammatory cells release a variety of chemicals and lead to cellular damage. The inflammation process also contributes to the loss of elastic recoil pressure in the lung, thereby reducing the driving pressure for expiratory flow through narr

Byssinosis is an occupational disease occurring commonly in cotton mill workers; it usually presents with features of chronic obstructive pulmonary disease (COPD). The management of patients with COPD presents a significant challenges to the anesthetist. Regional anesthesia is preferred in most of these patients to avoid perioperative and postoperative complications related to general anesthesia. We report a known case of Byssinosis who underwent nephrectomy under segmental spinal anesthesia at the low thoracic level.

Chronic obstructive pulmonary disease (COPD) is one of the serious late pulmonary complications caused by sulphur mustard exposure. Health status evaluations of chemical warfare patients with COPD are important to the management of these patients. The aim of this study was to determine the efficacy of the COPD assessment test (CAT) in evaluating the health-related quality of life (HRQOL) of chemical warfare patients with COPD. Eighty-two consecutive patients with stable COPD were enrolled in this study. All subjects were visited by one physician, and the HRQOL was evaluated by the CAT and St. George Respiratory Questionnaires (SGRQs). In addition, a standard spirometry test, 6-min walk distance test and pulse oxymetry were conducted. The severity of the COPD was determined using Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging and the body mass index, obstruction, dyspnoea and exercise (BODE) index. The mean age of the patients was 47.30 ± 7.08 years. The mean CAT score was 26.03 ± 8.28. Thirty-five (43%) patients were in CAT stage 3. There were statistically significant correlations between the CAT and the SGRQ (r = 0.70, P = 0.001) and the BODE index (r = 0.70, P = 0.001). A statistically significant inverse correlation was found between the CAT score and the forced expiratory volume in 1 s (r = -0.30, P = 0.03). Our results demonstrated that the CAT is a simple and valid tool for assessment of HRQOL in chemical warfare patients with COPD and can be used in clinical practice. © 2013 John Wiley & Sons Ltd.

Anterior urethral valve (AUV) is a long known but rare anomaly, which is occasionally encountered in boys with obstructive uropathy. We present a case of AUV with a diverticulum which was misdiagnosed at other center as neurogenic bladder resulting in chronic renal failure. The case was further complicated by breakage of tip of the catheter used for clean intermittent catheterization (CIC) in the diverticulum presenting as a foreign body in the urethra. This article highlights the frequently missed diagnosis of AUV by most practitioners wrongly labeling it as neurogenic bladder, leading to improper management and renal failure in young boys.

[Purpose] The aim of this study was to ascertain the prevalence of chronic widespread musculoskeletal pain in patients with obstructive sleep apnea syndrome and to assess the relationship between sleep disorder and pain, quality of life, and disability. [Subjects and Methods] Seventy-four patients were included in the study and classified as having mild, moderate, or severe obstructive sleep apnea. Chronic widespread pain, quality of life, and disability were evaluated. [Results] Forty-one patients (55.4%) had chronic widespread pain. Female patients had a higher incidence of chronic pain, and female patients with chronic pain had higher body mass indexes, pain levels, and disability scores than did male patients. Physical component scores of female patients with chronic pain were lower than those of male patients. No correlation was observed between the degree of sleep disorder and severity of pain, pain duration, disability, or quality of life in obstructive sleep apnea patients with pain. [Conclusion] This study showed a 55.4% prevalence of chronic widespread pain in patients with obstructive sleep apnea and a greater risk of chronic pain in female than in male patients. Female patients with obstructive sleep apnea and chronic pain have higher pain and disability levels and a lower quality of life.

Endoscopy and surgery are the treatment modalities of choice for patients with chronic pancreatitis and dilated pancreatic duct (obstructive chronic pancreatitis). Physicians face, without clear consensus, the choice between endoscopy or surgery for this group of patients. To assess and compare the effects and complications of surgical and endoscopic interventions in the management of pain for obstructive chronic pancreatitis. We searched the following databases in The Cochrane Library: CENTRAL (2014, Issue 2), the Cochrane Database of Systematic Reviews (2014, Issue 2), and DARE (2014, Issue 2). We also searched the following databases up to 25 March 2014: MEDLINE (from 1950), Embase (from 1980), and the Conference Proceedings Citation Index - Science (CPCI-S) (from 1990). We performed a cross-reference search. Two review authors independently performed the selection of trials. All randomised controlled trials (RCTs) of endoscopic or surgical interventions in obstructive chronic pancreatitis. We included trials comparing endoscopic versus surgical interventions as well as trials comparing either endoscopic or surgical interventions to conservative treatment (i.e. non-invasive treatment modalities). We included relevant trials irrespective of blinding, the number of participants randomised, and the language of the article. We used standard methodological procedures expected by The Cochrane Collaboration. Two authors independently extracted data from the articles. We evaluated the methodological quality of the included trials and requested additional information from study authors in the case of missing data. We identified three eligible trials. Two trials compared endoscopic intervention with surgical intervention and included a total of 111 participants: 55 in the endoscopic group and 56 in the surgical group. Compared with the endoscopic group, the surgical group had a higher proportion of participants with pain relief, both at middle/long-term follow-up (two to five years: risk ratio (RR) 1.62, 95% confidence interval (CI) 1.22 to 2.15) and long-term follow-up (≥ five years, RR 1.56, 95% CI 1.18 to 2.05). Surgical intervention resulted in improved quality of life and improved preservation of exocrine pancreatic function at middle/long-term follow-up (two to five years), but not at long-term follow-up (≥ 5 years). No differences were found in terms of major post-interventional complications or mortality, although the number of participants did not allow for this to be reliably evaluated. One trial, including 32 participants, compared surgical intervention with conservative treatment: 17 in the surgical group and 15 in the conservative group. The trial showed that surgical intervention resulted in a higher percentage of participants with pain relief and better preservation of pancreatic function. The trial had methodological limitations, and the number of participants was relatively small. For patients with obstructive chronic pancreatitis and dilated pancreatic duct, this review shows that surgery is superior to endoscopy in terms of pain relief. Morbidity and mortality seem not to differ between the two intervention modalities, but the small trials identified do not provide sufficient power to detect the small differences expected in this outcome.Regarding the comparison of surgical intervention versus conservative treatment, this review has shown that surgical intervention in an early stage of chronic pancreatitis is a promising approach in terms of pain relief and pancreatic function. Other trials need to confirm these results because of the methodological limitations and limited number of participants assessed in the present evidence.

Reviewed the epidemiology, clinical characteristics, mechanisms, and treatment of tuberculosis associated chronic obstructive pulmonary disease. We searched PubMed, EMBASE, and the CINAHL from inception to June 2016. We used the following search terms: Tuberculosis, COPD, Tuberculosis associated COPD, and so forth. All types of study were chosen. Chronic obstructive pulmonary disease (COPD) and tuberculosis are significant public health problems, particularly in developing countries. Although, smoking is the conventional risk factor for COPD, nonsmoking related risk factors such as biomass fuel exposure, childhood lower-respiratory tract infections, chronic asthma, outdoor air pollution, and prior history of pulmonary tuberculosis have become important risk factors of COPD, particularly in developing countries. Past history of tuberculosis as a risk factor of chronic airflow obstruction has been reported in several studies. It may develop during the course of tuberculosis or after completion of tuberculosis treatment. Developing countries with large burden of tuberculosis can contribute significantly to the burden of chronic airflow obstruction. Prompt diagnosis and treatment of tuberculosis should be emphasized to lessen the future burden of chronic airflow obstruction. © 2017 John Wiley & Sons Ltd.

The incidence of posterior urethral valve (PUV) is estimated at 1:5000-1:8000 males. It is the most common paediatric urologic urgency and the most common cause of male obstructive uropathy and chronic renal failure in children. The study aimed to describe the experience of Yaoundé gynaeco-obstetrics and paediatric hospital in the management of PUV. Retrospectively, medical records were retrieved over a ten year period and all data recorded and analyzed for study objectives. Patients were called and evaluated for outcomes regarding morbidity and mortality. A total of 18 patients all males were managed over the ten year period, given prevalence of 13 cases/100,000 admissions and an admission rate of 2 per annum. The median age at presentation was 22 months and 13 (72.2%) participants presented late. Voiding urethrocystogram was done in all the participants where it showed dilated and elongated posterior urethral valves in 16 (88.9%) of the cases. Endoscopic valve ablation resulted in the relief of obstruction in all but 3 (16.7%) participants that had residual valves and 2 (11.2%) participants that had urethral stenosis. Type I valves were most common in 14 (78.0%) participants. The mean duration of follow up was 34.56 ± 21.47 months. Complications at final follow up were: 10 (55.6%) chronic renal failure, 2 (11.2%) end-stage renal failure. The case fatality rate was 5.6%. Many patients present late in our setting with already established complications. There is the need to counsel parents/guardians on the importance of long-term follow up after relief of obstruction.

Chronic obstructive pulmonary disease and glucose metabolism: a bitter sweet symphony

PubMed Central

2012-01-01

Chronic obstructive pulmonary disease, metabolic syndrome and diabetes mellitus are common and underdiagnosed medical conditions. It was predicted that chronic obstructive pulmonary disease will be the third leading cause of death worldwide by 2020. The healthcare burden of this disease is even greater if we consider the significant impact of chronic obstructive pulmonary disease on the cardiovascular morbidity and mortality. Chronic obstructive pulmonary disease may be considered as a novel risk factor for new onset type 2 diabetes mellitus via multiple pathophysiological alterations such as: inflammation and oxidative stress, insulin resistance, weight gain and alterations in metabolism of adipokines. On the other hand, diabetes may act as an independent factor, negatively affecting pulmonary structure and function. Diabetes is associated with an increased risk of pulmonary infections, disease exacerbations and worsened COPD outcomes. On the top of that, coexistent OSA may increase the risk for type 2 DM in some individuals. The current scientific data necessitate a greater outlook on chronic obstructive pulmonary disease and chronic obstructive pulmonary disease may be viewed as a risk factor for the new onset type 2 diabetes mellitus. Conversely, both types of diabetes mellitus should be viewed as strong contributing factors for the development of obstructive lung disease. Such approach can potentially improve the outcomes and medical control for both conditions, and, thus, decrease the healthcare burden of these major medical problems. PMID:23101436

Chronic constipation is classified as outlet obstruction, colonic inertia or both. We aimed to determine the incidence of isolated colonic inertia in chronic constipation and to study symptom pattern in those with prolonged colonic transit time. Chronic constipation patients were classified radiologically by surgeon-reported defaecating proctography and transit study into four groups: isolated outlet obstruction, isolated colonic inertia, outlet obstruction plus colonic inertia, or normal. Symptom patterns were defined as stool infrequency (twice weekly or less) or frequent unsuccessful evacuations (more than twice weekly). Of 541 patients with chronic constipation, 289 (53%) were classified as isolated outlet obstruction, 26 (5%) as isolated colonic inertia, 159 (29%) as outlet obstruction plus colonic inertia and 67 (12%) as normal. Of 448 patients (83%) with outlet obstruction, 35% had additional colonic inertia. Only 14% of those with prolonged colonic transit time had isolated colonic inertia. Frequent unsuccessful evacuations rather than stool infrequency was the commonest symptom pattern in all three disease groups (isolated outlet obstruction 86%, isolated colonic inertia 54% and outlet obstruction plus colonic inertia 63%). Isolated colonic inertia is an unusual cause of chronic constipation. Most patients with colonic inertia have associated outlet obstruction. These data question the clinical significance of isolated colonic inertia. © 2011 The Authors. Colorectal Disease © 2011 The Association of Coloproctology of Great Britain and Ireland.

Recent advances in the management of radiation colitis

PubMed Central

Kountouras, Jannis; Zavos, Christos

2008-01-01

Radiation colitis, an insidious, progressive disease of increasing frequency, develops 6 mo to 5 years after regional radiotherapy for malignancy, owing to the deleterious effects of the latter on the colon and the small intestine. When dealing with radiation colitis and its complications, the most conservative modality should be employed because the areas of intestinal injury do not tend to heal. Acute radiation colitis is mostly self-limited, and usually, only supportive management is required. Chronic radiation colitis, a poorly predictable progressive disease, is considered as a precancerous lesion; radiation-associated malignancy has a tendency to be diagnosed at an advanced stage and to bear a dismal prognosis. Therefore, management of chronic radiation colitis remains a major challenge owing to the progressive evolution of the disease, including development of fibrosis, endarteritis, edema, fragility, perforation, partial obstruction, and cancer. Patients are commonly managed conservatively. Surgical intervention is difficult to perform because of the extension of fibrosis and alterations in the gut and mesentery, and should be reserved for intestinal obstruction, perforation, fistulas, and severe bleeding. Owing to the difficulty in managing the complications of acute and chronic radiation colitis, particular attention should be focused onto the prevention strategies. Uncovering the fibrosis mechanisms and the molecular events underlying radiation bowel disease could lead to the introduction of new therapeutic and/or preventive approaches. A variety of novel, mostly experimental, agents have been used mainly as a prophylaxis, and improvements have been made in radiotherapy delivery, including techniques to reduce the amount of exposed intestine in the radiation field, as a critical strategy for prevention.

Hereditary chronic pancreatitis

Rosendahl, Jonas; Bödeker, Hans; Mössner, Joachim; Teich, Niels

2007-01-01

Hereditary chronic pancreatitis (HCP) is a very rare form of early onset chronic pancreatitis. With the exception of the young age at diagnosis and a slower progression, the clinical course, morphological features and laboratory findings of HCP do not differ from those of patients with alcoholic chronic pancreatitis. As well, diagnostic criteria and treatment of HCP resemble that of chronic pancreatitis of other causes. The clinical presentation is highly variable and includes chronic abdominal pain, impairment of endocrine and exocrine pancreatic function, nausea and vomiting, maldigestion, diabetes, pseudocysts, bile duct and duodenal obstruction, and rarely pancreatic cancer. Fortunately, most patients have a mild disease. Mutations in the PRSS1 gene, encoding cationic trypsinogen, play a causative role in chronic pancreatitis. It has been shown that the PRSS1 mutations increase autocatalytic conversion of trypsinogen to active trypsin, and thus probably cause premature, intrapancreatic trypsinogen activation disturbing the intrapancreatic balance of proteases and their inhibitors. Other genes, such as the anionic trypsinogen (PRSS2), the serine protease inhibitor, Kazal type 1 (SPINK1) and the cystic fibrosis transmembrane conductance regulator (CFTR) have been found to be associated with chronic pancreatitis (idiopathic and hereditary) as well. Genetic testing should only be performed in carefully selected patients by direct DNA sequencing and antenatal diagnosis should not be encouraged. Treatment focuses on enzyme and nutritional supplementation, pain management, pancreatic diabetes, and local organ complications, such as pseudocysts, bile duct or duodenal obstruction. The disease course and prognosis of patients with HCP is unpredictable. Pancreatic cancer risk is elevated. Therefore, HCP patients should strongly avoid environmental risk factors for pancreatic cancer. PMID:17204147

Although previous studies have reported increased perioperative complications among obstructive sleep apnea (OSA) patients undergoing any surgery requiring general anesthesia, there is a paucity of literature addressing the impact of OSA on postoperative transsphenoidal surgery (TSS) complications. The aim of this study was to analyze postoperative outcomes in transsphenoidal pituitary surgery patients with OSA. Secondarily, we examined patient characteristics and comorbidities. Retrospective analysis. The 2002 to 2013 National Inpatient Sample was queried for patients undergoing TSS for pituitary neoplasm. Patients with an additional diagnosis of OSA were identified, and compared to a non-OSA cohort. There were 17,777 patients identified; 5.0% (N = 889) had an additional diagnosis of OSA. The OSA cohort had more comorbidities including diabetes mellitus, congestive heart failure, chronic pulmonary disease, coagulopathy, hypertension, hypothyroidism, liver disease, obesity, peripheral vascular disease, renal failure, acromegaly, and Cushing's syndrome. Postoperatively, OSA was independently associated with increased risks of tracheostomy (P = .015) and hypoxemia (P < .001), and decreased risk of cardiac complications (P = .034). OSA patients did not have increased rates of cerebrospinal fluid rhinorrhea, diabetes insipidus, reintubation, aspiration pneumonia, infectious pneumonia, thromboembolic complications, or urinary/renal complications. In-hospital mortality rates did not vary between the two cohorts. In patients who underwent transsphenoidal pituitary surgery, OSA was associated with higher rates of certain pulmonary and airway complications. OSA was not associated with increased non-pulmonary/airway complications or inpatient mortality, despite older average age and higher comorbidity rates. 2C.

to define optimal treatment of duodenal dystrophy in patients with chronic pancreatitis. 515 patients with chronic pancreatitis have been treated for the period 2004-2015 in A.V.Vishnevsky Institute of Surgery. Duodenal dystrophy (DD) was diagnosed in 79 (15.3%) of them. The diagnosis was confirmed by sonography, CT, MRI and endosonography. 5 patients are under observation without surgery. 74 patients were operated after previous medical therapy during 39 months on the average. Pancreatoduodenectomy was performed in 36 patients. Organ-sparing interventions were applied in 34 cases including different duodenal resections in 20 patients and pancreatic head resections in different modifications in 14 cases. 4 patients underwent palliative surgery. Chronic pancreatitis and DD were verified by morphological analysis of specimens. Long-term results were estimated in 47 patients. Median follow-up was 49.9 months. X-ray diagnostics showed that DD was combined with chronic pancreatitis in 87.3% of cases while morphological analysis revealed 93.8%. Clinical signs of DD were caused by striated pancreatitis in 69.6% and ectopic pancreatic tissue in 30.4%. Clinical manifestations of DD did not depend on its cause and were presented by symptoms of chronic pancreatitis. Postoperative complications occurred in 25 (34.7%) patients. There were 33.5% of complications after pancreatoduodenectomy and 70% after duodenal resection. 1 patient died. Overall mortality was 1,3%. In long-term period complete regression of symptoms was observed in 66% of cases, significant improvement - in 32%, absence of the effect - in 2%. Medical therapy should be preferred for patients with DD and chronic pancreatitis. Surgery is indicated in case of persistent pain, complicated course of chronic pancreatitis and duodenal obstruction. Pancreatoduodenectomy and pancreatic head resection are preferred.

Through the use of ubiquitous health, or u-Health, services, medical information can be adapted and made accessible via computer and Internet to provide quality healthcare to anybody, any place, and any time. We developed and implemented u-Health services for patients with chronic obstructive pulmonary disease and studied their experiences with respect to their knowledge of chronic obstructive pulmonary disease and skill and attitude toward the u-Health devices. The u-Health services were composed of telemonitoring and teleconsultation supplemented with home visits. To determine its effectiveness, the u-Health service system was implemented for 2 years with 144 chronic obstructive pulmonary disease patients in a clinical experiment. The subjects were divided into three experimental groups, each provided with different services, compared before and after intervention, and among groups. The analysis of data gathered through the system suggested that u-Health services can support patients with chronic obstructive pulmonary disease, improve patients' knowledge about chronic obstructive pulmonary disease self-management, build u-Health device usage skills, and foster a positive attitude toward u-Health devices. The u-Health services for the chronic obstructive pulmonary disease patients were both feasible and effective from the patients' perspective.

Chronic obstructive pulmonary disease induced by tobacco smoke has been regarded as a great health problem worldwide. The purpose of this study is to evaluate the protective effect of hydrogen-rich saline, a novel antioxidant, on chronic obstructive pulmonary disease and explore the underlying mechanism. Sprague-Dawley rats were made chronic obstructive pulmonary disease models via tobacco smoke exposure for 12 weeks and the rats were treated with 10 ml/kg hydrogen-rich saline intraperitoneally during the last 4 weeks. Lung function testing indicated hydrogen-rich saline decreased lung airway resistance and increased lung compliance and the ratio of forced expiratory volume in 0.1 s/forced vital capacity in chronic obstructive pulmonary disease rats. Histological analysis revealed that hydrogen-rich saline alleviated morphological impairments of lung in tobacco smoke-induced chronic obstructive pulmonary disease rats. ELISA assay showed hydrogen-rich saline lowered the levels of pro-inflammatory cytokines (IL-8 and IL-6) and anti-inflammatory cytokine IL-10 in bronchoalveolar lavage fluid and serum of chronic obstructive pulmonary disease rats. The content of malondialdehyde in lung tissue and serum was also determined and the data indicated hydrogen-rich saline suppressed oxidative stress reaction. The protein expressions of mucin MUC5C and aquaporin 5 involved in mucus hypersecretion were analyzed by Western blot and ELISA and the data revealed that hydrogen-rich saline down-regulated MUC5AC level in bronchoalveolar lavage fluid and lung tissue and up-regulated aquaporin 5 level in lung tissue of chronic obstructive pulmonary disease rats. In conclusion, these results suggest that administration of hydrogen-rich saline exhibits significant protective effect on chronic obstructive pulmonary disease through alleviating inflammation, reducing oxidative stress and lessening mucus hypersecretion in tobacco smoke-induced chronic obstructive pulmonary disease rats. Impact statement This study was designed to evaluate protective effect of hydrogen-rich saline, a novel antioxidant, on tobacco smoke (TS)-induced chronic obstructive pulmonary disease (COPD) in rats and explore the underlying mechanism. Our results suggest that administration of hydrogen-rich saline improves lung function and alleviates morphological impairments of lung through alleviating inflammation, reducing oxidative stress and lessening mucus hypersecretion in TS-induced COPD rats.

Little is known about using electronic medical records to identify patients with chronic obstructive pulmonary disease to improve quality of care. Our objective was to develop electronic medical record algorithms that can accurately identify patients with obstructive pulmonary disease. A retrospective chart abstraction study was conducted on data from the Electronic Medical Record Administrative data Linked Database (EMRALD ® ) housed at the Institute for Clinical Evaluative Sciences. Abstracted charts provided the reference standard based on available physician-diagnoses, chronic obstructive pulmonary disease-specific medications, smoking history and pulmonary function testing. Chronic obstructive pulmonary disease electronic medical record algorithms using combinations of terminology in the cumulative patient profile (CPP; problem list/past medical history), physician billing codes (chronic bronchitis/emphysema/other chronic obstructive pulmonary disease), and prescriptions, were tested against the reference standard. Sensitivity, specificity, and positive/negative predictive values (PPV/NPV) were calculated. There were 364 patients with chronic obstructive pulmonary disease identified in a 5889 randomly sampled cohort aged ≥ 35 years (prevalence = 6.2%). The electronic medical record algorithm consisting of ≥ 3 physician billing codes for chronic obstructive pulmonary disease per year; documentation in the CPP; tiotropium prescription; or ipratropium (or its formulations) prescription and a chronic obstructive pulmonary disease billing code had sensitivity of 76.9% (95% CI:72.2-81.2), specificity of 99.7% (99.5-99.8), PPV of 93.6% (90.3-96.1), and NPV of 98.5% (98.1-98.8). Electronic medical record algorithms can accurately identify patients with chronic obstructive pulmonary disease in primary care records. They can be used to enable further studies in practice patterns and chronic obstructive pulmonary disease management in primary care. NOVEL ALGORITHM SEARCH TECHNIQUE: Researchers develop an algorithm that can accurately search through electronic health records to find patients with chronic lung disease. Mining population-wide data for information on patients diagnosed and treated with chronic obstructive pulmonary disease (COPD) in primary care could help inform future healthcare and spending practices. Theresa Lee at the University of Toronto, Canada, and colleagues used an algorithm to search electronic medical records and identify patients with COPD from doctors' notes, prescriptions and symptom histories. They carefully adjusted the algorithm to improve sensitivity and predictive value by adding details such as specific medications, physician codes related to COPD, and different combinations of terminology in doctors' notes. The team accurately identified 364 patients with COPD in a randomly-selected cohort of 5889 people. Their results suggest opportunities for broader, informative studies of COPD in wider populations.

Nano-based theranostics for chronic obstructive lung diseases: challenges and therapeutic potential.

PubMed

Vij, Neeraj

2011-09-01

The major challenges in the delivery and therapeutic efficacy of nano-delivery systems in chronic obstructive airway conditions are airway defense, severe inflammation and mucous hypersecretion. Chronic airway inflammation and mucous hypersecretion are hallmarks of chronic obstructive airway diseases, including asthma, COPD (chronic obstructive pulmonary disease) and CF (cystic fibrosis). Distinct etiologies drive inflammation and mucous hypersecretion in these diseases, which are further induced by infection or components of cigarette smoke. Controlling chronic inflammation is at the root of treatments such as corticosteroids, antibiotics or other available drugs, which pose the challenge of sustained delivery of drugs to target cells or tissues. In spite of the wide application of nano-based drug delivery systems, very few are tested to date. Targeted nanoparticle-mediated sustained drug delivery is required to control inflammatory cell chemotaxis, fibrosis, protease-mediated chronic emphysema and/or chronic lung obstruction in COPD. Moreover, targeted epithelial delivery is indispensable for correcting the underlying defects in CF and targeted inflammatory cell delivery for controlling other chronic inflammatory lung diseases. We propose that the design and development of nano-based targeted theranostic vehicles with therapeutic, imaging and airway-defense penetrating capability, will be invaluable for treating chronic obstructive lung diseases. This paper discusses a novel nano-theranostic strategy that we are currently evaluating to treat the underlying cause of CF and COPD lung disease.

Tracheobtenosib and tracheomalacia are trivial diseases. The conventional choice of managements with tracheostomy, either temporary or long-term usage, can only partially resolve the problems of airway obstruction. Silicone tracheal T-tube presents a substitute for it. We present 5 patients with tracheostenosis or tracheomalacia managed with nine procedures of long silicone Montgomery T-tube prothesis between 1984 and 1994 in VGH-Taipei. The primary diagnosis included tracheal injury (2), postintubation tracheal stenosis (2), and stenosis due to endotracheal tuberculosis (1). Three patients received a long segmental T-tube for permanent endotracheal stenting and the other two patients used T-tube insertion for temporary stenting of the trachea for 7 and 11 months, respectively, with satisfactory results. All patients got immediate benefit from the prothesis in respiration with simple postoperative care. Two patients with temporary T-tube placement had it successfully removed in 7 and 11 months, respectively. Placement of the T-tube for subglottic stenosis also protected the function of phonation. The tracheal T-tube restored airway patency reliably with good long-term results and could be the preferred management of chronic upper airway obstructive disease not amenable to surgical repair. The most common complication was airway obstruction caused by either granulations or sticky mucoid substance. Three patients and six tubes (60%) developed granulation obstruction and the average duration of granuloma formation was 7.7 months. Laser phototherapy or surgical intervention, such as tracheoplasty, with change of the T-tube was carried out for granuloma obstruction. T-tube is a good endoprothesis for tracheostenosis and tracheomalacia with minimal complication for cases of long tracheostenosis or complex tracheal injury.

Unlocking the limitations: Living with chronic obstructive pulmonary disease and receiving care through telemedicine-A phenomenological study.

To describe the lived experiences of quality of life among a group of patients living with chronic obstructive pulmonary disease who were included in a telemedical intervention after hospitalisation for disease exacerbation. Patients with chronic obstructive pulmonary disease have high symptom burden, poor control of symptoms and a need for greater requirements in care. Telemedicine can provide benefits for patients with chronic obstructive pulmonary disease by improving self-management. Descriptive phenomenological approach. Ten in-depth interviews were conducted with chronic obstructive pulmonary disease patients participating in a telemedical intervention. The collected data were analysed using a descriptive phenomenological research method. Living with chronic obstructive pulmonary disease was experienced as creating physical and mental limitations of the diseased body and an increasing identity as a patient, which led to impaired quality of life. Being included in the telemedicine intervention increased accessibility to healthcare services and support from telemedicine nurses. Self-measurement of health data increased participants' clinical insight and created a mutual clinical language in dialogue with telemedicine nurses, which led to increased quality of life. However, receiving care through telemedicine was also experienced as a dual chore. Telemedicine can reduce the perceived limitations imposed by chronic obstructive pulmonary disease through four key elements: (i) improving accessibility to healthcare services, (ii) increasing support from health professionals, (iii) strengthening clinical insight and (iv) developing a mutual clinical language, thus increasing quality of life. The transparency facilitated through telemedicine in this healthcare context encourages open decision-making, where the participants can increase their knowledge and improve acknowledgement of and collaboration with telemedicine nurses. Telemedicine can be beneficial when rethinking care for chronic obstructive pulmonary disease by providing knowledge on how living with chronic obstructive pulmonary disease can affect the experience of receiving care through telemedicine and further determine for whom telemedicine is useful. © 2017 John Wiley & Sons Ltd.

Eleven instances of a mixed acid-base disorder consisting of chronic respiratory acidosis and metabolic alkalosis were recognized in eight patients with chronic obstructive lung disease and carbon dioxide retention. Correction of the metabolic alkalosis led to substantial improvement in blood gas values and clinical symptoms. Patients with mixed chronic respiratory acidosis and metabolic alkalosis constitute a common subgroup of patients with chronic obstructive lung disease and carbon dioxide retention; these patients benefit from correction of the metabolic alkalosis.

1963-01-01

In chronic obstructive lung disease (asthma, chronic bronchitis, obstructive emphysema) there is a segmental reduction in the caliber of the airways, which always results in obstruction to air-flow. Increased airway resistance is a physiological expression of airway obstruction. The addition of inspiratory flow rate control to an intermittent positive pressure breathing device permits slow filling of a lung with obstructed airways, and is presented as a simple means of reducing the high pulmonary flow resistance and increasing the tidal volume.

Urinary tract infection (UTI) is a common cause of severe sepsis, and anatomic urologic obstruction is a recognized factor for complicated disease. We aimed to identify the incidence of urinary obstruction complicating acute septic shock and determine the characteristics and outcomes of this group. Patients prospectively enrolled in a sepsis treatment pathway registry between October 2013 and July 2014 were reviewed for the diagnosis of UTI. Standardized medical record review was performed to confirm sepsis due to UTI and determine clinical variables including the presence of anatomic urinary obstruction. Patients with septic shock due to UTI with obstruction were compared with those without obstruction. The primary outcomes were incidence of urinary obstruction and hospital mortality. Among 1084 registry enrollees, 209 (19.2%) met inclusion criteria for the study. Acute anatomic obstruction was identified in 22 (10.5%) patients. Hospital mortality in patients with obstruction was 27.3% compared with 11.2% in patients without obstruction (absolute difference of 16.1%; P = .03; 95% confidence interval [CI], 1.2%-30.9%). Hospital length of stay among survivors was 12.8 days compared with 8.3 days (absolute difference of 4.5 days; P = .04; 95% CI, 0.2-8.8 days). History of urinary stone disease was independently associated with obstruction (odds ratio, 5.6; 95% CI, 2.2-14.3). Approximately 1 in 10 patients presenting with septic shock due to a urinary source is complicated by anatomic urinary obstruction. These patients have significantly higher mortality compared with patients without obstruction. Early imaging of patients with septic shock due to suspected urinary source should be considered to identify obstruction requiring emergency intervention. Copyright © 2015 Elsevier Inc.

Functional aerophagia in children: a frequent, atypical disorder.

PubMed

Morabito, Giuliana; Romeo, Claudia; Romano, Claudio

2014-01-01

Aerophagia is a functional gastrointestinal disorder characterized by repetitive air swallowing, abdominal distension, belching and flatulence. Pathologic aerophagia is a condition caused by the swallowing of excessive volumes of air with associated various gastrointestinal symptoms, such as burping, abdominal cramps, flatulence and a reduced appetite. It is a clinical entity that can simulate pediatric gastrointestinal motility disorders, such as gastroparesis, megacolon and intestinal pseudo-obstruction, and presents more frequently in children with mental retardation. Early recognition and diagnosis of functional aerophagia or pathologic aerophagia is required to avoid unnecessary, expensive diagnostic investigations or serious clinical complications. Functional aerophagia is frequent in the adult population, but rarely discussed in the pediatric literature. We present two pediatric clinical cases with a history of functional constipation in whom gaseous abdominal distension was the most important symptom. Mechanical intestinal obstruction, chronic intestinal pseudo-obstruction, malabsorption and congenital aganglionic megacolon were ruled out. Extensive gaseous abdominal distension was due to aerophagia, and treatment consisted of parents' reassurance and psychological counseling.

2018-02-01

The effects of chronic corticosteroid therapy on complications, readmission, and reoperation after posterior lumbar fusion (PLF) remain underinvestigated, and were examined to determine differences in outcomes. We analyzed patients undergoing PLF between 2006 and 2013 using the National Surgery Quality Improvement Program database (NSQIP). Patients taking steroids for a chronic condition were compared with those not taking steroids. Multivariable regression identified factors independently associated with complications, readmission, and reoperation. A risk score was calculated for predicting complications. A total of 8492 patients were identified, of whom 353 used steroids. The patients using steroids were older (mean age, 65.4 years vs. 61.0 years; P < 0.001), were more likely to be female (61.2% vs. 55.1%; P = 0.025), had a higher American Society of Anesthesiologists class (P < 0.001), were less likely to be functionally independent (90.3% vs. 96.5%; P < 0.001), and were more likely to have a history of hypertension (69.1% vs. 58.3%; P < 0.001), diabetes mellitus (21.8% vs. 17.4%; P = 0.033), cardiac disease (74.8% vs. 66.1%; P = 0.001), and/or severe chronic obstructive pulmonary disease (10.5% vs. 4.2%; P < 0.001). The rates of readmission (9.4% vs. 6.0%; P = 0.023), reoperation (6.5% vs. 3.6%; P = 0.004), overall complications (14.5% vs. 9.6%; P = 0.003), and infections (9.6% vs. 5.1%; P < 0.001) were higher in the steroid group. On multivariable regression, steroids were independently associated with overall complications (odds ratio [OR], 1.38; P = 0.044) and infectious complications (OR, 1.65; P < 0.001), but not with medical complications, readmission, or reoperation. Patients with higher risk scores had higher complication rates. The use of corticosteroid therapy is associated with a moderately increased risk of overall complications, but no association was found with readmission or reoperation. Copyright © 2017.

Noninvasive ventilation plays a pivotal role in acute ventilator failure and has been shown, in certain disease processes such as acute exacerbation of chronic obstructive pulmonary disease, to prevent and shorten the duration of invasive mechanical ventilation, reducing the risks and complications associated with it. The application of noninvasive ventilation is relatively simple and well tolerated by patients and in the right setting can change the course of their illness. Copyright © 2017 Elsevier Inc.

Graft versus host disease: what should the oculoplastic surgeon know?

PubMed

Tung, Cynthia I

2017-09-01

To provide a concise review of the oculoplastic manifestations of ocular graft versus host disease (GVHD), and to discuss their management. Ocular GVHD occurs as a common immune-mediated complication of hematopoietic stem cell transplantation that presents as a Stevens-Johnson-like syndrome in the acute phase or a Sjögren-like syndrome in the chronic phase. Cicatricial conjunctivitis may be underreported in ocular GVHD. The spectrum of oculoplastic manifestations includes GVHD of the skin, cicatricial entropion, nasolacrimal duct obstruction, and lacrimal gland dysfunction. Surgical treatment is indicated for patients with significant corneal complications from entropion. Surgical approach to repair of nasolacrimal duct obstruction is presented in this review, including modified approaches for treating patients at risk for keratitis sicca. Management of the ocular graft versus host patient may require a multidisciplinary approach involving collaboration from the oculoplastic surgeon, the corneal specialist, and the stem cell transplant physician. Oculoplastic manifestations of ocular GVHD typically present as cicatricial changes in the eyelid and lacrimal system. Careful oculoplastic and corneal evaluation are necessary when considering surgical management for the ocular GVHD patient.

Foreign body aspiration in adult airways: therapeutic approach

Tracheobronchial foreign body (FB) aspiration is an uncommon but potentially life-threatening event in adults. Symptoms typically consist of a choking event followed by cough and dyspnea, however, these findings are inconsistent and symptoms may mimic more chronic lung diseases such as asthma or chronic obstructive pulmonary disease. Chest radiography and computed tomography can provide information regarding the location and characteristics of foreign bodies and aid in diagnosis. Bronchoscopy remains the gold standard for diagnosis and management of FB aspiration. The authors describe the typical clinical presentation, diagnostic evaluation, and bronchoscopic management of foreign bodies in adult airways with a focus on bronchoscopic techniques and potential complications of FB extraction.

2018-01-01

Self-expandable metal stents are widely used to treat malignant colorectal obstruction. However, data on clinical outcomes of stent placement for rectal obstruction specifically are lacking. We aimed to investigate the clinical outcomes of self-expandable metal stents in malignant rectal obstruction in comparison with those in left colonic obstruction and to identify factors associated with clinical failure and complication. This was a retrospective study. The study was conducted at a tertiary care center. Between January 2005 and December 2013, medical charts of patients who underwent stent placement for malignant rectal or left colonic obstruction were reviewed retrospectively. Study intervention included self-expandable metal stent placement. Technical success, clinical success, and complications were measured. Technical success rates for the 2 study groups (rectum vs left colon, 93.5% vs 93.1%; p = 0.86) did not differ significantly; however, the clinical success rate was lower in patients with rectal obstruction (85.4% vs 92.1%; p = 0.02). In addition, the complication rate was higher in patients with rectal obstruction (37.4% vs 25.1%; p = 0.01). Patients with rectal obstruction showed higher rates of obstruction because of extracolonic malignancy (33.8% vs 15.8%; p < 0.001) and stent use for palliation (78.6% vs 56.3%; p < 0.001). Multivariate analysis indicated obstruction attributed to extracolonic malignancy and covered stent usage to be independent risk factors for clinical failure. Factors predictive of complications in the palliative group were total obstruction, obstruction because of extracolonic malignancy, and covered stent usage. This was a retrospective, single-center study. The efficacy and safety of stent placement for malignant rectal obstruction were comparable with those for left colonic obstruction. However, obstruction attributed to extracolonic malignancy, use of covered stents, and total obstruction negatively impacted clinical outcomes of self-expandable metal stent placement and must be considered by endoscopists.

The results of examination and treatment of 445 patients with chronic pancreatitis were analyzed. It was established, that 298 (67%) patients had indications for treatment in the conditions of surgical hospital. The patients were divided into three groups according to the modified pancreatitis classification of Marseilles-Rome 1988. There were the calcifying form (n = 78), obstructive form (n = 81), inflammatory form (n = 139). The application of modern methods of diagnostics and treatment of chronic pancreatitis allowed modifying the classification by selection of subgroups for each form of the disease. It was stated, that the substantiation of variants of surgical treatment of chronic pancreatitis in consideration of morphological changes in the pancreas could improve the possibilities of medical care plan for patients with minimal complications and good quality of life in long-term period of time.

There is still uncertainty regarding the efficacy and optimal modalities of extracorporeal shock wave lithotripsy (ESWL) in the treatment of chronic pancreatitis. The aims of the present study were to assess the safety and the efficacy of ESWL, either alone or followed by therapeutic endoscopic retrograde cholangiopancreatography (adjuvant ERCP) and to determine predictive factors of efficacy, in a real-life setting. This study included all consecutive patients who underwent an ESWL in a single University Hospital between 2001 and 2012. The indication for ESWL was obstructive stone(s) of the main pancreatic duct resulting in either painful chronic pancreatitis or recurrent acute pancreatitis. Success was defined by resolution of pain, no analgesic treatment, no acute pancreatitis and no surgical treatment for chronic pancreatitis 6 months after the ESWL. One hundred and forty-six patients were studied; 6/146 (4%) had a complication of ESWL. Among the 132 patients in whom follow-up was completed, 91 (69%) had an adjuvant ERCP. After 6 months of follow-up, 100/132 (76%) patients achieved success. In multivariate analysis, the single significant predictive factor of the success of the ESWL treatment was chronic pain (p = 0.03). Patients who had chronic pain and needed opioid treatment had less chance of success than patients without chronic pain (OR 95%CI 0.31 [0.07-1.14]). We found no difference in the success rates between patients who underwent adjuvant ERCP and those who had ESWL only (p = 0.93). This study shows that the ESWL is a safe and effective treatment for patients with chronic pancreatitis and obstructive stones within the main pancreatic duct. Systematic association with therapeutic ERCP appears to provide no additional benefit and is therefore not recommended.

Although it is known that patients with chronic obstructive pulmonary disease (COPD) generally do have an increased heart rate, the effects on both mortality and non-fatal pulmonary complications are unclear. We assessed whether heart rate is associated with all-cause mortality, and non-fatal pulmonary endpoints. A prospective cohort study of 405 elderly patients with COPD was performed. All patients underwent extensive investigations, including electrocardiography. Follow-up data on mortality were obtained by linking the cohort to the Dutch National Cause of Death Register and information on complications (exacerbation of COPD or pneumonia) by scrutinizing patient files of general practitioners. Multivariable cox regression analysis was performed. During the follow-up 132 (33%) patients died. The overall mortality rate was 50/1000 py (42-59). The major causes of death were cardiovascular and respiratory. The relative risk of all-cause mortality increased with 21% for every 10 beats/minute increase in heart rate (adjusted HR: 1.21 [1.07-1.36], p = 0.002). The incidence of major non-fatal pulmonary events was 145/1000 py (120-168). The risk of a non-fatal pulmonary complication increased non-significantly with 7% for every 10 beats/minute increase in resting heart rate (adjusted HR: 1.07 [0.96-1.18], p = 0.208). Increased resting heart rate is a strong and independent risk factor for all-cause mortality in elderly patients with COPD. An increased resting heart rate did not result in an increased risk of exacerbations or pneumonia. This may indicate that the increased mortality risk of COPD is related to non-pulmonary causes. Future randomized controlled trials are needed to investigate whether heart-rate lowering agents are worthwhile for COPD patients.

Noninvasive positive-pressure ventilation (NPPV) might be superior to conventional mechanical ventilation (CMV) in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPDs). Inefficient clearance of respiratory secretions provokes NPPV failure in patients with hypercapnic encephalopathy (HE). This study compared CMV and NPPV combined with a noninvasive strategy for clearing secretions in HE and AECOPD patients.The present study is a prospective cohort study of AECOPD and HE patients enrolled between October 2013 and August 2015 in a critical care unit of a major university teaching hospital in China.A total of 74 patients received NPPV and 90 patients received CMV. Inclusion criteria included the following: physician-diagnosed AECOPD, spontaneous airway clearance of excessive secretions, arterial blood gas analysis requiring intensive care, moderate-to-severe dyspnea, and a Kelly-Matthay scale score of 3 to 5. Exclusion criteria included the following: preexisting psychiatric/neurological disorders unrelated to HE, upper gastrointestinal bleeding, upper airway obstruction, acute coronary syndromes, preadmission tracheostomy or endotracheal intubation, and urgent endotracheal intubation for cardiovascular, psychomotor agitation, or severe hemodynamic conditions.Intensive care unit participants were managed by NPPV. Participants received standard treatment consisting of controlled oxygen therapy during NPPV-free periods; antibiotics, intravenous doxofylline, corticosteroids (e.g., salbutamol and ambroxol), and subcutaneous low-molecular-weight heparin; and therapy for comorbidities if necessary. Nasogastric tubes were inserted only in participants who developed gastric distension. No pharmacological sedation was administered.The primary and secondary outcome measures included comparative complication rates, durations of ventilation and hospitalization, number of invasive devices/patient, and in-hospital and 1-year mortality rates.Arterial blood gases and sensorium levels improved significantly within 2 hours in the NPPV group with lower hospital mortality, fewer complications and invasive devices/patient, and superior weaning off mechanical ventilation. Mechanical ventilation duration, hospital stay, or 1-year mortality was similar between groups.NPPV combined with a noninvasive strategy to clear secretions during the first 2 hours may offer advantages over CMV in treating AECOPD patients complicated by HE.

2014-01-01

Introduction The literature presents studies correlating chronic obstructive pulmonary disease to dysphagia and suggesting that the aspiration laryngeal phenomenon related to changes in the pharyngeal phase contributes significantly to the exacerbation of symptoms of lung disease. Objectives This study aimed to conduct a literature review to identify the relation between dysphagia and exacerbations of chronic obstructive pulmonary disease. Data Synthesis We found 21 studies and included 19 in this review. The few studies that related to the subject agreed that the presence of dysphagia, due to lack of coordination between swallowing and breathing, may be one of the triggering factors of chronic obstructive pulmonary disease exacerbation. Conclusions The review noted that there is a relationship between dysphagia and exacerbations of chronic obstructive pulmonary disease, identified by studies demonstrating that the difficulties associated with swallowing may lead to exacerbation of the disease. There was difficulty in comparing studies by their methodological differences. More research is needed to clarify the relationship between dysphagia and exacerbations of chronic obstructive pulmonary disease, making it possible to develop multiprofessional treatment strategies for these patients, catered to specific needs due to the systemic manifestations of the disease.

During the first 18 month operation of the isolated lung transplantation program at or Institution, eight patients with terminal chronic respiratory failure underwent fiberoptic bronchoscopy and broncho-alveolar lavage as part of their evaluation for isolated lung transplantation. Four patients had severe obstructive, three restrictive, and one mixed, obstructive and restrictive, disease; all of them were on continuous supplemental oxygen. Procedures were performed under topical anaesthesia, with either light sedation or simple monitored anaesthesia care. Monitoring included non-invasive blood pressure measurement, pulse oximeter and precordial stethoscope. No adverse events were recorded, except in one case, when pulse oximeter reading precipitously dropped below 80%, to a minimum of 68-69%. The procedures was terminated short of its completion, and the patient was briefly assisted with manual bag ventilation on oxygen 100%. Pulse oximeter quickly returned to normal levels (above 90%), and the patient promptly recovered, without complications. The importance of monitored anaesthesia care during fiberoptic bronchoscopy (a usually benign procedure) in critically ill patients is greatly emphasized.

To explore the illness experiences of older patients with late-stage chronic obstructive pulmonary disease and to develop knowledge about how patients perceive their preferences to be taken into account in decision-making processes concerning mechanical ventilation and/or noninvasive ventilation. Decisions about whether older patients with late-stage chronic obstructive pulmonary disease will benefit from noninvasive ventilation treatment or whether the time has come for palliative treatment are complicated, both medically and ethically. Knowledge regarding patients' values and preferences concerning ventilation support is crucial yet often lacking. Qualitative design with a hermeneutic-phenomenological approach. The data consist of qualitative in-depth interviews with 12 patients from Norway diagnosed with late-stage chronic obstructive pulmonary disease. The data were analysed within the three interpretative contexts described by Kvale and Brinkmann. The participants described their lives as fragile and burdensome, frequently interrupted by unpredictable and frightening exacerbations. They lacked information about their diagnosis and prognosis and were often not included in decisions about noninvasive ventilation or mechanical ventilation. Findings indicate that these patients are highly vulnerable and have complex needs in terms of nursing care and medical treatment. Moreover, they need access to proactive advanced care planning and an opportunity to discuss their wishes for treatment and care. To provide competent care for these patients, healthcare personnel must be aware of how patients experience being seriously ill. Advanced care planning and shared decision-making should be initiated alongside the curative treatment. © 2017 John Wiley & Sons Ltd.

The difficult asthmatic.

Gregg, I

1977-01-01

The most common reason why asthma presents difficulties in management is the failure to treat it with drugs which are appropriate and taken in adequate dosage. An understanding of the pathophysiology and aetiology of asthma is essential if full advantage is to be taken of the wide range of drugs now available for treating it. Airflow obstruction due to bronchial muscle constriction is usually readily reversible by bronchodilators, whereas that due to the inflammatory component of asthma is refractory to the latter and can only be reversed by steroids. Refractory airflow obstruction is liable to be confused with irreversible obstruction which occurs in those patients whose asthma is complicated by chronic obstructive bronchitis or other lung disease. The choice between symptomatic, preventive and suppressive forms of treatment should be made only after a careful assessment has been carried out with objective measurement of airflow obstruction. The Wright peak flow meter is unsurpassed for this purpose. By its means it should be possible to estimate how much of a patient's airflow obstruction is readily reversible, how much is refractory and how much is irreversible. In general, the aim of treatment is to relieve airflow obstruction rather than to counteract supposed aetiological factors. Both doctor and patient must understand the purpose, limitations and possible dangers of any drug which is prescribed. Steroids are the only form of treatment which is effective in persistent refractory asthma. Prejudice against steroids has resulted in many patients being deprived of their benefit, but this situation may change with the recent introduction of steroid aerosols.

Our goal was to assess the association of computed tomographic measures of airway wall volume and lumen volume with the FEV1 and chronic airflow obstruction in smokers with childhood-onset asthma. Methods: We analyzed clinical, lung function, and volumetric computed tomographic airway volume data from 7,266 smokers, including 590 with childhood-onset asthma. Small wall volume and small lumen volume of segmental airways were defined as measures 1 SD below the mean. We assessed the association between small wall volume, small lumen volume, FEV1, and chronic airflow obstruction (post-bronchodilator FEV1/FVC ratio < 0.7) using linear and logistic models. Measurements and Main Results: Compared with subjects without childhood-onset asthma, those with childhood-onset asthma had smaller wall volume and lumen volume (P < 0.0001) of segmental airways. Among subjects with childhood-onset asthma, those with the smallest wall volume and lumen volume had the lowest FEV1 and greatest odds of chronic airflow obstruction. A similar tendency was seen in those without childhood-onset asthma. When comparing these two groups, both small wall volume and small lumen volume were more strongly associated with FEV1 and chronic airflow obstruction among subjects with childhood-asthma in multivariate models. Conclusion: In smokers with childhood-onset asthma, smaller airways are associated with reduced lung function and chronic airflow obstruction.

Introduction Self-expanding metallic stents (SEMS) for palliative purposes in malignant colonic obstruction are an alternative to surgery that has gained popularity over time. Methods We performed a retrospective study of patients submitted to SEMS for palliation of obstructing malignant colorectal cancer from 2005 to 2015 to evaluate predictive clinical factors for complications and mortality. Results Forty-five patients with high rates of technical and clinical success were included (97.8 and 95.6%, respectively), with complications occurring in 17.8% (8.9% perforations, 4.4% obstructions, and 4.4% migrations). The length of the stenosis was superior in patients with complications (p = 0.01); 11.1% of patients had a re-intervention (2.2% surgery and 8.9% placement of another SEMS). Relief of obstruction without intervention was maintained until death in 77.8% of patients and in 81.4% of patients who had immediate clinical success. The mortality rate was 37.2% at 30 days, 56.5% at 60 days, and 87.5% at 1 year. There were no predictors of survival identified, including age, sex, tumor stage, metastasis, or complications of the procedure. Discussion and Conclusions In this study, SEMS placement was associated with a high rate of technical and clinical success and a low rate of complications, being an option to palliate patients with obstructive neoplasia. The length of the stenosis was associated with a greater risk of complications. The majority of stent-related complications can be managed successfully without surgery. PMID:28848796

Chronic obstructive pulmonary disease and chronic heart failure: two muscle diseases?

Chronic obstructive pulmonary disease and congestive heart failure are two increasingly prevalent chronic diseases. Although care for these patients often is provided by different clinical teams, both disease conditions have much in common. In recent decades, more knowledge about the systemic impact of both diseases has become available, highlighting remarkable similarities in terms of prognostic factors and disease management. Rehabilitation programs deal with the systemic consequences of both diseases. Although clinical research also is conducted by various researchers investigating chronic obstructive pulmonary disease and chronic heart failure, it is worthwhile to compare the progress in relation to these two diseases over recent decades. Such comparison, the purpose of the current review, may help clinicians and scientists to learn about progress made in different, yet related, fields. The current review focuses on the similarities observed in the clinical impact of muscle weakness, the mechanisms of muscle dysfunction, the strategies to improve muscle function, and the effects of exercise training on chronic obstructive pulmonary disease and chronic heart failure.

In the present study the effect of defibrotide, an antithrombotic and profibrinolytic agent, was investigated in patients with chronic venous insufficiency (CVI) due to deep vein obstruction and/or reflux (chronic deep vein insufficiency, CDVI). The study was a multicenter, randomized, double blind placebo controlled trial in which only patients with CDVI confirmed by ultrasound were enrolled. All patients were treated with adequate elastic compression and randomized to receive either oral defibrotide (800 mg/die) or matching placebo for 1 year. Patients with active or previous leg ulcer were excluded. A total of 288 patients were randomized and 159 completed the study. At baseline ultrasound investigation, obstructive changes were found in 2/3 of all patients thus ascertaining a post-thrombotic syndrome (PTS). The primary endpoint, ankle circumference, was significantly reduced under defibrotide from day 120 throughout 360. Scores for pain and edema were improved. The number of episodes of superficial thrombophlebitis and deep vein thrombosis was significantly lower under defibrotide (n=2) than under placebo (n=10). The majority of these events occurred in the subset of patients with documented PTS. Treatment with defibrotide in addition to elastic compression in patients with objectively assessed CDVI, mostly due to PTS, resulted in clinical benefits and prevented thrombotic complications harmful to the limb conditions.

Prevention of chronic obstructive pulmonary disease hospital readmissions is an international priority aimed to slow disease progression and limit costs. Evidence of the risk of readmission and of interventions that might prevent it is lacking. We aimed to determine readmission risk for chronic obstructive pulmonary disease, factors influencing that risk, and variation in readmission risk between hospitals across 7.5 million people in London. This retrospective longitudinal observational study included all chronic obstructive pulmonary disease admissions to any hospital in the United Kingdom among patients registered at London general practices who had emergency National Health Service chronic obstructive pulmonary disease hospital admissions between April 2006 and March 2010. Influence of patient characteristics, geographical deprivation score, length of stay, day of week of admission or of discharge, and admitting hospital, were assessed using multiple logistic regression. 38,894 chronic obstructive pulmonary disease admissions of 20,932 patients aged ≥ 45 years registered with London general practices were recorded. 6295 patients (32.2%) had at least one chronic obstructive pulmonary disease readmission within 1 year. 1993 patients (10.2%) were readmitted within 30 days and 3471 patients (17.8%) were readmitted within 90 days. Age and patient geographical deprivation score were very weak predictors of readmission. Rates of chronic obstructive pulmonary disease readmissions within 30 days and within 90 days did not vary among the majority of hospitals. The finding of lower chronic obstructive pulmonary disease readmission rates than was previously estimated and the limited variation in these rates between hospitals suggests that the opportunity to reduce chronic obstructive pulmonary disease readmission risk is small. LOWER RISK OF READMISSION FOR LONDON-BASED PATIENTS: A managed reduction of hospital readmissions for London-based chronic lung disease patients may not be needed. Preventing hospital readmissions for patients with chronic obstructive pulmonary disease (COPD) is a key priority to improve patient care and limit costs. However, few data are available to determine and ultimately reduce the risk of readmission. Timothy Harries at King's College, London, and co-workers conducted a longitudinal study incorporating all COPD admissions into UK hospitals for 20,932 patients registered at London general practitioners between 2006 and 2010. They found that 32% of patients were readmitted within a year, 17.8% within 90 days and 10% within 30 days. Neither age nor geographical deprivation were useful predictors of readmission. These represent lower than estimated levels of readmission, suggesting there may be fewer opportunities to reduce the risk of readmission further.

There is a paucity of data on the demographic and clinicopathological profiles of patients with chronic pancreatitis from the eastern part of India. This study documents the demographic and clinicopathological profiles of patients with chronic pancreatitis presenting to a general surgery unit of a tertiary referral hospital of Kolkata. The records of 145 patients presenting with chronic pancreatitis over a 5-year period were scrutinized and their demographics, clinical profile, and complications and morphological changes of the pancreas are described. Of the 145 patients, more than 50% were under the age of 30 years. Males were affected more frequently than females (M/F = 3.8:1). While idiopathic pancreatitis was the most common form of chronic pancreatitis (41.4%), alcohol was found to be the most common etiology (37.9%). Pain was the most common presenting symptom (n = 143; 98.6%). Sixty-five subjects (45%) had diabetes of which 32 subjects were insulin-dependent. On contrast-enhanced computed tomography, ductal dilatation was seen in 80 (55.17%) subjects, while ductal calculi and ductal dilatation in 54 cases (37.2%). Parenchymal calcification was seen in 45 patients of whom 40 patients (89%) were under the age of 30 years. Pseudocyst was the most common complication (n = 16) followed by biliary obstruction (n = 8) and portal hypertension (n = 4). Patients with alcoholic pancreatitis had significantly higher frequency of severe abdominal pain, diabetes, and local complications as compared to the other forms of pancreatitis in our study. Idiopathic pancreatitis was the most common form of chronic pancreatitis in this study, followed by alcoholic pancreatitis and then tropical pancreatitis.

Chronic intestinal pseudo-obstruction (CIPO) is a rare disorder characterised by recurrent symptoms and signs of intestinal obstruction without an underlying mechanical cause. Caecal volvulus remains a rare cause of intestinal obstruction that often requires operative intervention. We describe the previously unreported case of caecal volvulus occurring in an adult patient with CIPO, together with his subsequent management. PMID:22004621

BACKGROUND The aim of this study was to evaluate the curative effect of transvaginal mesh repair (TVMR) and stapled transanal rectal resection (STARR) in treating outlet obstruction constipation caused by rectocele. MATERIAL AND METHODS Patients who had outlet obstruction constipation caused by rectocele were retrospectively analyzed and 39 patients were enrolled the study. Patients were assigned to either the TVMR or STARR group. Postoperative factors such as complications, pain, recurrence rate, and operative time were compared between the 2 groups. RESULTS Total effective rate was 100% in both groups. No long-term chronic pain occurred and discomfort rate of tenesmus was higher in the STARR group than in the TVMR group. Postoperative defecography showed that the rectocele depth was significantly reduced, and the prolapse of the rectal mucosa and the lower rectal capacity was also decreased. Four cases had mesh exposure in the TVMR group and 2 cases in the STARR group had anastomotic bleeding after the surgery. CONCLUSIONS For outlet obstruction constipation caused by rectocele, TVMR and STARR both obtained satisfactory results. Although TVMR is complex with longer operative time and hospitalization period, its long-term effect is better than that of STARR.

The incidence and prevalence of peptic ulcer disease has decreased in recent years, but it is not so easy to make the same conclusion when complications of peptic ulcer are taken into consideration. The aim of this study is to determine the time trends in complicated peptic ulcer disease and to state the effects of H2 receptor blockers, proton pump inhibitors (PPI), and H. pylori eradication therapies on these complications. This study retrospectively evaluated the patients who were operated on for complications (perforation, bleeding, and obstruction) of peptic ulcer for the last 50 years. Patients were grouped into four groups (G1-G4) according to the dates in which H2 receptor blockers, PPIs, and eradication regimens for H. pylori were introduced The time periods that were studied were: (G1) 1962-1980, (G2) 1981-1990, (G3) 1991-1997, and (G4) 1998-2012. In total, 2953 patients were operated on for complications of peptic ulcer disease, of which 86% of the patients were male. In G1, perforation and obstruction were significantly the most frequent complications (p<0.001), followed by bleeding. In groups G2 and G3, obstruction was still the most frequent complication requiring surgery (p<0.001). In G2 and G3, obstruction was followed by perforation and bleeding, respectively. In G4, perforation was significantly the most frequent complication (p<0.001). From 1962 to 1990 obstruction was the most common complication requiring surgery. In the last decade, perforation became the most common complication. In contrast to reports in the literature, bleeding was the least common complication requiring surgery in Turkey.

Endoscopy and surgery are the treatment modalities of choice in patients with obstructive chronic pancreatitis. Physicians face the decision between endoscopy and surgery for this group of patients, without clear consensus. To assess and compare the effectiveness and complications of surgical and endoscopic interventions in the management of pain for obstructive chronic pancreatitis. We searched The Cochrane Library, MEDLINE, EMBASE and the Conference Proceedings Citation Index; and performed a cross-reference search. Two review authors performed the selection of trials independently. All randomised controlled trials (RCTs) investigating endoscopic or surgical interventions for obstructive chronic pancreatitis. All trials were included irrespective of blinding, number of patients randomised and language of the article. Two authors independently extracted data from the articles. The methodological quality of included trials was evaluated. Authors were requested additional information in the case of missing data. We screened 2082 publications and identified three eligible trials. Two trials compared endoscopic intervention to surgical intervention. These included a total of 111 patients, 55 in the endoscopic group and 56 in the surgical group. A higher proportion of patients with pain relief was found in the surgical group compared to the endoscopic group (partial or complete pain relief: RR 1.62, 95% confidence interval (CI) 1.11 to 2.37; complete pain relief: RR 2.45, 95% CI 1.18 to 5.09). Surgical intervention resulted in improved quality of life and improved preservation of exocrine pancreatic function in one trial. The number of patients did not allow for a reliable evaluation of morbidity and mortality between the two treatment modalities. One trial compared surgical intervention to conservative treatment. It included 32 patients: 17 in the surgical group and 15 in the conservative group. The trial showed that surgical intervention resulted in a higher percentage of patients with pain relief and better preservation of pancreatic function. The trial had methodological limitations and the number of patients was relatively small. For patients with obstructive chronic pancreatitis and dilated pancreatic duct, this review showed that surgery is superior to endoscopy in terms of pain control. Morbidity and mortality seemed not to differ between the two intervention modalities, but the small trials identified do not provide sufficient power to detect the small differences expected in this outcome.Regarding the comparison of surgical intervention versus conservative treatment, this review has shown that surgical intervention in an early stage of chronic pancreatitis seems to be a promising approach in terms of pain control and pancreatic function. Confirmation of these results is needed in other trials due to the methodological limitations and limited number of patients of the present evidence.

Chronic obstructive pulmonary disease is the fifth leading cause of mortality in the world. This study reviews diet as a risk or protective factor for chronic obstructive pulmonary disease, mechanisms of malnutrition, undernutrition consequences on body functioning and how to modulate nutritional status of patients with chronic obstructive pulmonary disease. Different dietary factors (dietary pattern, foods, nutrients) have been associated with chronic obstructive pulmonary disease and the course of the disease. Mechanical disadvantage, energy imbalance, disuse muscle atrophy, hypoxemia, systemic inflammation and oxidative stress have been reported to cause systemic consequences such as cachexia and compromise whole body functioning. Nutritional intervention makes it possible to modify the natural course of the disease provided that it is included in respiratory rehabilitation combining bronchodilators optimization, infection control, exercise and, in some patients, correction of hypogonadism. Diet, as a modifiable risk factor, appears more as an option to prevent and modify the course of chronic obstructive pulmonary disease. Reduction of mechanical disadvantage, physical training and anabolic agents should be used conjointly with oral nutrition supplements to overcome undernutrition and might change the prognosis of the disease in some cases. Major research challenges address the role of systemic inflammation and the best interventions for controlling it besides smoking cessation.

Limited data exist concerning the unique pain characteristics of patients with non-cancer terminal diseases referred for inpatient hospice care. To define the unique pain characteristics of patients admitted to an acute inpatient hospice setting with end-stage dementia or chronic obstructive lung disease (or chronic obstructive pulmonary disease) and to compare them to patients with end-stage cancer. Retrospective patient chart review. Demographic, physiological, pain parameters, and medication utilization data were extracted. Associations between pain characteristics, medication utilization, and admission diagnoses were assessed. Analyses included descriptive statistics. In total, 146 patients admitted to an acute inpatient hospice between 1 April 2011 and 31 March 2012 with an underlying primary diagnosis of chronic obstructive pulmonary disease (n = 51), dementia (n = 48), or cancer (n = 47). Pain was highly prevalent in all diagnostic groups, with cancer patients experiencing more severe pain on admission. Cancer patients received a significantly higher cumulative opioid dose compared with dementia and chronic obstructive pulmonary disease patients. Pain control within 24 h of pain onset was achieved in less than half of all patient groups with chronic obstructive pulmonary disease patients the least likely to achieve pain control. Despite the fact that pain is the most common complaint at the end of life, pain management may be suboptimal for some primary diagnoses. Admission diagnosis is the strongest predictor of pain control. Patient with cancer achieve the best pain control, and chronic obstructive pulmonary disease patients are the least likely to have their pain adequately treated. © The Author(s) 2015.

Endoscopic therapy of acute and chronic pancreatitis has decreased the need for operative intervention. However, a significant proportion of patients treated endoscopically require definitive surgical management for persistent symptoms. Our aim was to determine which patients are likely to fail with endoscopic therapy, and to assess the clinical outcome of surgical management. Patients were identified using ICD-9 codes for pancreatic disease as well as CPT codes for endoscopic therapy followed by surgery. Patients with documented acute or chronic pancreatitis treated endoscopically prior to surgical therapy were included (N = 88). The majority of patients (65%) exhibited chronic pancreatitis due to alcohol abuse. Common indicators for surgery were: persistent symptoms, anatomy not amenable to endoscopic treatment and unresolved common bile duct or pancreatic duct strictures. Surgical salvage procedures included internal drainage of a pseudocyst or an obstructed pancreatic duct (46%), debridement of peripancreatic fluid collections (25%), and pancreatic resection (31%). Death occurred in 3% of patients. The most common complications were hemorrhage (16%), wound infection (13%), and pulmonary complications (11%). Chronic pancreatitis with persistent symptoms is the most common reason for pancreatic surgery following endoscopic therapy. Surgical salvage therapy can largely be accomplished by drainage procedures, but pancreatic resection is common. These complex procedures can be performed with acceptable mortality but also with significant risk for morbidity.

Female genital mutilation (FGM) comprises all procedures involving partial or total removal of the external genitalia and/or any other procedures affecting the female genitalia, for cultural or religious reasons or for nontherapeutic purposes in general. FGM is responsible for a number of short-, medium-, and long-term complications that can engage the vital and functional prognosis, especially in African countries. We report on a case in a 10-year-old girl who underwent genital mutilation, a traditional type of total excision during the neonatal period. She was followed for urethral meatus stenosis, which then was complicated by obstructive chronic kidney failure and urinary sepsis, whose progression was fatal. Copyright © 2017 Elsevier Masson SAS.

Endoscopic third ventriculostomy (ETV) has become standard for obstructive hydrocephalus. Even a successful ETV can obstruct, leading to recurrence of symptoms and even death. A possible solution to this problem is leaving an Ommaya reservoir (OR) following the ETV. OR can be tapped in an emergency and for diagnostic purposes. No specific complications have been attributed to OR in this setting. We present our experience with OR in children undergoing ETV for hydrocephalus. A retrospective study was conducted in hydrocephalic children that underwent ETV with OR insertion over 13 years (1997-2010) from a single institution. Data were collected from charts and follow-ups. Twelve patients (from 200 patients who had an ETV) underwent placement of OR with ETV. OR was reserved for a subgroup of patients in whom we anticipated complications-in children that presented with acute hydrocephalus and were in deteriorating condition, for pathologies believed to have a low predicted ETV success rate, or when the surgeon felt that the ETV procedure was suboptimal. OR was tapped in eight patients. Complications occurred in four patients: two cases of subdural effusion, one case of chronic subdural hematoma, and one CSF leak. Four ORs were removed due to complications, and four were converted to shunts. OR should be considered in selected patients undergoing ETV. Despite its obvious advantages, OR may be associated with a relatively high risk of extraaxial fluid collections. This association requires further investigation.

What can happen after lung transplantation and the importance of the time since transplantation: radiological review of post-transplantation complications.

Lung transplantation is the best treatment option in the final stages of diseases such as cystic fibrosis, pulmonary hypertension, chronic obstructive pulmonary disease, or idiopathic pulmonary fibrosis. Better surgical techniques and advances in immunosuppressor treatments have increased survival in lung transplant recipients, making longer follow-up necessary because complications can occur at any time after transplantation. For practical purposes, complications can be classified as early (those that normally occur within two months after transplantation), late (those that normally occur more than two months after transplantation), or time-independent (those that can occur at any time after transplantation). Many complications have nonspecific clinical and radiological manifestations, so the time factor is key to narrow the differential diagnosis. Imaging can guide interventional procedures and can detect complications early. This article aims to describe and illustrate the complications that can occur after lung transplantation from the clinical and radiological viewpoints so that they can be detected as early as possible.

A serious but rare complication of laparoscopic adjustable gastric banding: bowel obstruction due to caecal volvulus.

PubMed

Agahi, Afshin; Harle, Robin

2009-08-01

Laparoscopic adjustable gastric banding (LAGB) is a widely performed surgical procedure for the treatment of morbid obesity. LAGB complications have declined since its development in the early 1990s. However, LAGB complications are still occurring and can sometimes be serious and life threatening. These complications are related either to the band or to the access port, such as band slippage or tubing disconnection, retrospectively. We report a rare case of bowel obstruction due to caecal volvulus caused by connecting tube used in LAP-BAND system in a bariatric operation, which obstructed a caecal loop, in a female who had undergone LAGB 2 years previously. Diagnosis of bowel obstruction was established with plain abdominal radiograph appearances. Follow-up abdominal computed tomography findings confirmed the diagnosis of caecal obstruction and revealed the underlying cause for this obstruction. Surgery was performed, and intraoperative examination demonstrated that connecting tube of the LAP-BAND system was a main causative factor. We can hypothesize that bowel obstruction secondary to LAGB operation may become frequently diagnosed as more LAGB operations performed worldwide. The emergence of many problems, such as this, can be minimized with enhancement in the development of better surgical materials, proper operative technique, and close postoperative management and follow-up.

Pathobiology of tobacco smoking and neurovascular disorders: untied strings and alternative products.

2015-10-31

Tobacco smoke (TS) is the leading cause of preventable deaths worldwide. In addition to a host of well characterized diseases including chronic obstructive pulmonary disease, oral and peripheral cancers and cardiovascular complications, epidemiological evidence suggests that chronic smokers are at equal risk to develop neurological and neurovascular complications such as multiple sclerosis, Alzheimer's disease, stroke, vascular dementia and small vessel ischemic disease (SVID). Unfortunately, few direct neurotoxicology studies of tobacco smoking and its pathogenic pathways have been produced so far. A major link between TS and CNS disorders is the blood-brain barrier (BBB). In this review article, we summarize the current understanding of the toxicological impact of TS on BBB physiology and function and major compensatory mechanisms such as nrf2- ARE signaling and anti-inflammatory pathways activated by TS. In the same context, we discuss the controversial role of antioxidant supplementation as a prophylactic and/or therapeutic approach in delaying or decreasing the disease complications in smokers. Further, we cover a number of toxicological studies associated with "reduced exposure" cigarette products including electronic cigarettes. Finally, we provide insights on possible avenues for future research including mechanistic studies using direct inhalation rodent models.

Treatment of psychological factors in a child with difficult asthma: a case report.

PubMed

Anbar, Ran D; Sachdeva, Shagun

2011-07-01

Difficult asthma is defined as the persistence of asthma symptoms, abnormal pulmonary function showing airway obstruction, and continued requirement for short-acting bronchodilator therapy, despite adequate treatment with inhaled corticosteroids. It calls for a thorough evaluation of the patient to look into alternate and complicating diagnoses. The authors report a case of a 9-year-old patient with difficult asthma who failed to respond to conventional therapy. Although it was recognized that he had a number of potential medical complicating factors including allergies, chronic sinusitis, and gastroesophageal reflux, a psychological intervention using hypnosis ultimately appeared to help alleviate his symptoms completely. Thus, psychological evaluation and intervention should be considered early in the course of management of a patient with difficult asthma, because it may help avoid time-consuming and expensive investigations of potential complicating factors, and it may yield rapid improvement in the patient's clinical condition.

Many patients with chronic illnesses report a desire for increased involvement in medical decision-making. This pilot study aimed to explore how patients with exacerbation-prone disease trajectories such as advanced heart failure or chronic obstructive pulmonary disease experience advance care planning using an online decision aid and to compare whether patients with different types of exacerbation-prone illnesses had varied experiences using the tool. Pre-intervention questionnaires measured advance care planning knowledge. Post-intervention questionnaires measured: (1) advance care planning knowledge; (2) satisfaction with tool; (3) decisional conflict; and (4) accuracy of the resultant advance directive. Comparisons were made between patients with heart failure and chronic obstructive pulmonary disease. Over 90% of the patients with heart failure (n = 24) or chronic obstructive pulmonary disease (n = 25) reported being "satisfied" or "highly satisfied" with the tool across all satisfaction domains; over 90% of participants rated the resultant advance directive as "very accurate." Participants reported low decisional conflict. Advance care planning knowledge scores rose by 18% (p < 0.001) post-intervention. There were no significant differences between participants with heart failure and chronic obstructive pulmonary disease. Patients with advanced heart failure and chronic obstructive pulmonary disease were highly satisfied after using an online advance care planning decision aid and had increased knowledge of advance care planning. This tool can be a useful resource for time-constrained clinicians whose patients wish to engage in advance care planning. © The Author(s) 2016.

To synthesise findings from previously published studies on the effectiveness of self-management programmes for people with chronic obstructive pulmonary disease. Self-management is a widely valued concept to address contemporary issues of chronic health problems. Yet, findings of self-management programmes for people with chronic obstructive pulmonary disease are indecisive. Literature review of (1) previously published systematic reviews and (2) an integrative literature review. Synthesis of findings from previously published systematic reviews (n = 4) of the effectiveness of self-management programmes for people with chronic obstructive pulmonary disease and an integrated review that was performed on papers published between January 2007-June 2012 (n = 9). Findings demonstrate that there are few studies on the effectiveness of self-management programmes on people with chronic obstructive pulmonary disease despite more than a decade of research activities. Outcomes of the studies reveal some increase in health-related quality of life and reduction in use of healthcare resources. The methodological approaches vary, and the sample size is primarily small. Families are not acknowledged. Features of patient-centredness exist in self-management programmes, particularly in the more recent articles. The effectiveness of self-management programmes for people with chronic obstructive pulmonary disease remains indecisive. A reconceptualisation of self-management programmes is called for with attention to a family-centred, holistic and relational care focusing on living with and minimising the handicapping consequences of the health problems in their entirety. © 2013 Blackwell Publishing Ltd.

The benefits of manual versus automated red blood cell exchange have rarely been documented and studies in young sickle cell disease patients are scarce. We aim to describe and compare our experience in these two procedures. Young patients (≤ 21 years old) who underwent manual- or automated-red blood cell exchange for prevention or treatment of sickle cell disease complications were included. Clinical, technical and hematological data were prospectively recorded and analyzed. Ninety-four red blood cell exchange sessions were performed over a period of 68 months, including 57 manual and 37 automated, 63 for chronic complications prevention, 30 for acute complications and one in the pre-operative setting. Mean decrease in sickle hemoglobin levels was higher in automated-red blood cell exchange (p < 0.001) and permitted a higher sickle hemoglobin level decrease per volume removed (p < 0.001), while hemoglobin and hematocrit remained stable. Ferritin levels on chronic patients decreased 54%. Most frequent concern was catheter outflow obstruction on manual-red blood cell exchange and access alarm on automated-red blood cell exchange. No major complication or alloimunization was recorded. Automated-red blood cell exchange decreased sickle hemoglobin levels more efficiently than manual procedure in the setting of acute and chronic complications of sickle cell disease, with minor technical concerns mainly due to vascular access. The threshold of sickle hemoglobin should be individualized for clinical and hematological goals. In our cohort of young patients, the need for an acceptable venous access was a limiting factor, but iron-overload was avoided. Automated red blood cell exchange is safe and well tolerated. It permits a higher sickle hemoglobin removal efficacy, better volume status control and iron-overload avoidance.

Airway stenting is a well-established method that relieves symptoms and maintains airway patency in patients with airway obstruction. Serious complications caused by airway stents such as stent dislocation and airway obstruction during surgery are life-threatening. An 80-year-old man was treated with bronchial stent for left bronchus obstruction caused by metastatic esophageal cancer. During tracheostomy surgery, he suffered from acute tracheal obstruction caused by dislocated bronchial stent. Esophageal cancer, left bronchus obstruction, respiratory failure, tracheal obstruction. Threading a 5.0-sized endotracheal tube combined with an Eschmann tracheal tube introducer to prop up the collapsed stent. The bronchial stent was re-expanded and threaded into right main bronchus and ventilation restored. Patient with airway stent undergoing surgery with airway involved should be performed under the support of a backup physician and equipment that are capable of handling potentially life-threatening complications of airway stent. If not, in the emergent situation of tracheal obstruction due to tracheal/bronchial stent, protruding through the stent with a suitable, small-sized endotracheal tube with Eschmann tracheal tube introducer may be an alternative skill for saving life weighted with possible complications.

The purpose of this study was to identify patient-related factors that may explain the increased likelihood of receiving a respiratory-related clinician action in patients identified to be at risk for chronic obstructive pulmonary disease in a U.S.-based pragmatic study of chronic obstructive pulmonary disease screening. This post hoc analysis (conducted in 2014-2015) of the Screening, Evaluating and Assessing Rate Changes of Diagnosing Respiratory Conditions in Primary Care 1 (SEARCH1) study (conducted in 2010-2011), used the chronic obstructive pulmonary disease Population Screener questionnaire in 112 primary care practices. Anyone with a previous chronic obstructive pulmonary disease diagnosis was excluded. Multivariate logistic regression modeling was used to assess patient factors associated with the likelihood of receiving an respiratory-related clinician action following positive screening. Overall, 994 of 6,497 (15%) screened positive and were considered at risk for chronic obstructive pulmonary disease. However, only 187 of the 994 patients (19%) who screened positive received a respiratory-related clinician action. The chances of receiving a respiratory-related clinician action were significantly increased in patients who visited their physician with a respiratory issue (p<0.05) or had already been prescribed a respiratory medication (p<0.05). Most (81%) patients who screened positive or had a respiratory-related clinician action had one or more comorbidity, including cardiovascular disease (68%), diabetes (30%), depression/anxiety (26%), asthma (11%), and cancer (9%). Routine chronic obstructive pulmonary disease screening appears to promote respiratory-related clinician actions in patients with a high likelihood for disease who have respiratory complaints or already use prescribed respiratory medication.

2017-04-01

This paper was a report of the synthesis of evidence on examining the origins and definitions of the concept of resilience, investigating its application in chronic illness management and exploring its utility as a means of understanding family caregiving of adults with Chronic Obstructive Pulmonary Disease. Resilience is a concept that is becoming relevant to understanding how individuals and families live with illness, especially long-term conditions. Caregivers of adults with Chronic Obstructive Pulmonary Disease must be able to respond to exacerbations of the condition and may themselves experience cognitive imbalances. Yet, resilience as a way of understanding family caregiving of adults with COPD is little explored. Literature review - integrative review. CINAHL, PubMed, Google Scholar and EBSCO were searched between 1989-2015. The principles of rapid evidence assessment were followed. We identified 376 relevant papers: 20 papers reported the presence of the concept of resilience in family caregivers of chronic diseases patients but only 12 papers reported the presence of the concept of resilience in caregivers of Chronic Obstructive Pulmonary Disease patients and have been included in the synthesis. The term resilience in Chronic Obstructive Pulmonary Disease caregiving is most often understood using a deficit model of health.

To assess the disease spectrum, severity of airflow limitation, admission pattern, co-morbidities, and management of patients admitted for acute exacerbations of chronic obstructive pulmonary disease. Case series. An acute regional hospital in Hong Kong. Adult subjects admitted during January 2010 to December 2010 with the principal discharge diagnosis of chronic obstructive pulmonary disease. In all, the records of 253 patients with physician-diagnosed chronic obstructive pulmonary disease were analysed. The majority were old (mean age, 78 years). The median number of admissions per patient for this condition in 2010 was two. About two thirds (64%) had had spirometry at least once. Mean forced expiratory volume in one second predicted was 55%. Almost 90% had moderate-to-very severe airflow limitation by spirometry. Overall, long-acting bronchodilators (beta agonists and/or antimuscarinics) were being prescribed for only 21% of the patients. Most of the patients admitted to hospital for acute exacerbations of chronic obstructive pulmonary disease were old, had multiple co-morbidities, and the majority had moderate-to-severe airflow limitation by spirometry. Almost half of them (around 46%) had two or more admissions in 2010. Adherence to the latest treatment guidelines seemed inadequate, there being a low prescription rate of long-acting bronchodilators. Chronic obstructive pulmonary disease patients warranting emergency admissions are at risk of future exacerbations and mortality. Management by a designated multidisciplinary team is recommended.

The purpose of this study was to investigate the etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population. The clinical data of 142 patients with chronic pancreatitis were retrospectively studied. All patients were of Chinese nationality and hospitalized from January 2008 to December 2011. Their ages ranged from 14 to 76 years, with a mean of 43 years. Of 142 patients, there were 72 cases of obstructive chronic pancreatitis (50.70%), 19 cases of alcoholic chronic pancreatitis (13.38%), 14 cases of autoimmune pancreatitis (9.86%) and 37 cases of undetermined etiology (26.06%). Pathologically, the average inflammatory mass diameter was 3.8 ± 3.3 cm, biliary obstruction occurred in 36 cases, gall stones in 70 cases, calcification in 88 cases, ductal dilatation in 61 cases, side branch dilatation in 32 cases, ductal irregularity in 10 cases, lymphocytic inflammation in 23 cases, obliterative phlebitis in 14 cases, extra pancreatic lesion in 19 cases and fibrosis in 142 cases. Location of pancreatic lesion in the region of head (n=97), neck (n=16), body (n=12), tail (n=15) and whole pancreas (n=2) influenced the choice of surgical procedures. Ninety-four patients (66.20%) received surgical treatment and 33.80% received other treatments. After operation, 80.85% of 94 patients experienced decreased pain, and 8.51% of 94 showed recovery of endocrine function but with a complication rate of 12.77%. All the operations were performed successfully. According to the pain scale of European Organization for Research and Treatment of Cancer (QLQ-C30) a decrease from 76 ± 22 to 14 ± 18 was observed. Etiology, pathological characteristics, management and prognosis of chronic pancreatitis in the Chinese population vary from others.

Provisionally patient was started on CPAP and long-term domiciliary oxygen therapy (LTOT). OSA was successfully treated by surgical repair of nasal patency and partial uvulectomy. There was also remarkable improvement in ventilatory indices after steroid therapy. There was no further need for CPAP and LTOT.

Systemic inflammation in chronic obstructive pulmonary disease and lung cancer: common driver of pulmonary cachexia?

PubMed

Ceelen, Judith J M; Langen, Ramon C J; Schols, Annemie M W J

2014-12-01

In this article, a putative role of systemic inflammation as a driver of pulmonary cachexia induced by either chronic obstructive pulmonary disease or nonsmall cell lung cancer is reviewed. Gaps in current translational research approaches are discussed and alternative strategies are proposed to provide new insights. Activation of the ubiquitin proteasome system has generally been considered a cause of pulmonary cachexia, but current animal models lack specificity and evidence is lacking in nonsmall cell lung cancer and conflicting in chronic obstructive pulmonary disease patients. Recent studies have shown activation of the autophagy-lysosome pathway in both nonsmall cell lung cancer and chronic obstructive pulmonary disease. Myonuclear loss, as a consequence of increased apoptotic events in myofibers, has been suggested in cancer-cachexia-associated muscle atrophy. Plasma transfer on myotube cultures can be used to detect early inflammatory signals in patients and presence of atrophy-inducing activity within the circulation. Comparative clinical research between nonsmall cell lung cancer and chronic obstructive pulmonary disease in different disease stages is useful to unravel disease-specific versus common denominators of pulmonary cachexia.

Chronic obstructive parotitis related to Sjogren syndrome is not uncommon, but it is rarely reported in the literature. The aim of this study was to describe our experience in the treatment of chronic obstructive parotitis related to Sjogren syndrome. Seventeen cases of chronic obstructive parotitis related to Sjogren syndrome treated with sialendoscopy from June 2014 to June 2015 at the Department of Oral and Maxillofacial Surgery, School of Stomatology, China Medical University, were retrospectively reviewed. The cohort underwent ultrasonography, salivary gland scintigraphy, and sialography before sialendoscopy. All patients were asked to complete a visual analogue scale (VAS) evaluation before and 6 months after surgery. A paired t test was conducted, and P < .05 was considered statistically significant. The 17 study patients (27 parotid glands) successfully underwent interventional sialendoscopy under local anesthesia. The mean preoperative VAS score was 6, and the mean VAS score 6 months after sialendoscopy was significantly lower at 4.5 (P < .05). Interventional sialendoscopy plays a significant role in the treatment of chronic obstructive parotitis related to Sjogren syndrome. Copyright © 2016 Elsevier Inc. All rights reserved.

Endoscopy and cross-sectional imaging for assessing Crohn׳s disease activity

Crohn’s disease (CD) is principally characterized by chronic and recurrent inflammation of the gastrointestinal tract, most commonly found in the ileo-colonic region. The chronicity and severity of intestinal inflammation together contribute to progressive, cumulative, deep, transmural intestinal damage, including stricturing, obstruction, abscesses, and fistulae. Both intestinal inflammation and its chronic complications result in a range of symptoms subsequently leading to patient presentations with diarrhea, abdominal pain, and anemia related to intestinal blood loss. Measuring disease activity and severity are essential for decision of treatment intensity early in the disease course and longitudinal monitoring of therapeutic efficacy. This review will summarize the transition from subjective symptoms driving disease activity indices, into increasingly objective and quantitative measures of intestinal injury by direct mucosal assessment (endoscopy), cross-sectional imaging, and surrogate biomarkers. Specific commentary on intestinal stricture and perianal fistula assessment and management are presented in accompanying sections of this series. PMID:28458507

Acute esophageal necrosis (AEN) is a rare clinical disorder. Esophageal stenosis or obstruction is one of severe complications, but there are a few reports about surgical treatments. In such a situation, it still remains controversial which to choose, esophagectomy or bypass operation. A 61-year-old woman was admitted to the local hospital for septic shock with diabetic ketoacidosis due to necrotizing fasciitis of the right thigh. Three days later, she had hematemesis, and gastrointestinal endoscopy revealed black mucosal coloration throughout the entire esophagus. She was diagnosed as having AEN. Her general condition improved after intensive care, debridement, and treatment with antibiotics and a proton pump inhibitor; the esophageal mucosal color recovered. However, an esophageal stricture developed after 1 month, and the patient underwent gastrostomy to remove an esophageal obstruction after 3 months. She was referred to our hospital for surgical treatment 1 year and 4 months after the occurrence of AEN because of her strong desire for oral intake. Her medical condition was poor, and she could not walk due to generalized muscle weakness. After rehabilitation for 8 months, we performed an esophageal bypass using a gastric conduit via the percutaneous route rather than esophagectomy because of her multiple severe comorbidities including walking difficulty, chronic hepatitis C, cerebrovascular disease, and chronic renal failure. Minor leakage of the esophagogastrostomy occurred and was resolved with conservative treatment. The patient began oral intake on postoperative day 34 and was discharged on day 52. Esophageal obstruction after AEN was successfully treated by esophageal bypass using a gastric conduit in a high-risk patient. Because the majority of patients with AEN have multiple severe comorbidities, assessing the medical condition of the patient adequately is important prior to choosing either an esophagectomy or bypass surgery.

The objective of this clinical trial was to assess the safety and efficacy of radiofrequency (RF) tissue ablation of the inferior turbinates in the treatment of nasal obstruction using an RF energy delivery system with a thermocouple feedback electrode. A prospective, nonrandomized study of 11 patients (mean age, 47+/-12 y) with chronic nasal obstruction was conducted. Using patient-based visual analogue scales (VAS), symptom parameters were assessed. These included degree of nasal obstruction, frequency of nasal obstruction, and pain. Physician assessment of nasal obstruction was also collected by the principal investigator. Follow-up was conducted at 24 hours, 1 week, 4 weeks, 8 weeks, and 1 year. ANOVA was carried out to determine statistically significant differences in the data. Data were fit to a regression model, and confidence intervals were determined from a 95% confidence level. In patient-assessed degree of nasal obstruction, statistical significance was seen among baseline and 4 weeks, 8 weeks, and 1 year (P<.001, P<.0001, and P<.0008, respectively). There was no difference between 8 weeks and 1 year (P<.15). The data appeared to follow an exponential decay to a constant value. The pretreatment baseline average degree of obstruction was 7.5+/-0.5 on a scale of 0 to 10. The degree of obstruction after 8 weeks was 2.7+/-0.6. The time constant for this change was 21 days to reach 90% of the final value. At 1 year, degree of obstruction was 3.3+/-0.7. For frequency of nasal obstruction, statistical significance was seen among baseline and 4 weeks, 8 weeks, and 1 year (P<.0001, P<.0001, and P<.0001, respectively). There was no difference between 8 weeks and 1 year (P<.15). The pretreatment baseline average frequency of obstruction was 7.8+/-0.5. The remaining frequency of obstruction after 8 weeks was 2.9+/-0.6. The time constant was 18 days. At 1 year, frequency of obstruction was 3.3+/-0.6. Physician assessment of nasal obstruction revealed statistical significance among baseline and 4 weeks, and baseline and 8 weeks (P<.0055 and P<.0056, respectively). There was no difference between 4 weeks and 8 weeks (P<.24). The average initial obstruction was 83%+/-4%. The remaining obstruction after 8 weeks was 58% +/-5%. The time constant was 14 days. Mild pain was reported by 55% of patients during the procedure; the remaining 45% reported no pain. Only one patient required pain medication consisting of acetaminophen after the procedure. There were no significant complications. Degree and frequency of nasal obstruction, as reported by patients, decreased following RF tissue ablation of the inferior turbinates. This improvement in symptoms was still evident after 1 year (P<.001). Physician assessment of obstruction also correlated with patient reports for the initial 8-week study period. The procedure was safe and well tolerated. Thermocouples within the active electrode provided additional feedback to the operating surgeon allowing the use of relatively lower tissue temperatures, power, and energy as compared with traditional techniques. These results support the need for continued research to evaluate this modality as a treatment for chronic nasal obstruction.

The microdebrider is a surgical tool which has been used successfully in many endoscopic surgical procedures in otolaryngology. In this study, we analysed our experience using this powered instrument in the resection of obstructive nasal septum deviations. This was a longitudinal, prospective, descriptive study conducted between January and June 2007 on 141 patients who consulted for chronic nasal obstruction caused by a septal deviation or deformity and underwent powered endoscopic septoplasty (PES). The mean age was 39.9 years (15-63 years); 60.28% were male (n=85) The change in nasal symptom severity decreased after surgery from 6.12 (preoperative) to 2.01 (postoperative). Patients undergoing PES had a significant reduction of nasal symptoms in the pre- and postoperative period, which was statistically significant (P<.05). There were no statistically significant differences between the results at the 2 nd week, 6th week and 5th year after surgery. The 100% of patients were satisfied with the results of surgery and no patient answered "No" to the question added to compare patient satisfaction after surgery. Minor complications in the postoperative period were present in 4.96% of the cases. Powered endoscopic septoplasty allows accurate, conservative repair of obstructive nasal septum deviations, with fewer complications and better functional results. In our experience, this technique offered significant perioperative advantages with high postoperative patient satisfaction in terms of reducing the severity of nasal symptoms.

Chronic obstructive pulmonary disease prevalence rates are still high. However, the majority of subjects are not diagnosed. Strategies have to be implemented to overcome the problem of under-diagnosis. Questionnaires could be used to pre-select subjects for spirometry and thereby help reducing under-diagnosis. We report a brief, simple, self-administrable and validated chronic obstructive pulmonary disease questionnaire to increase the pre-test probability for chronic obstructive pulmonary disease diagnosis in subjects undergoing confirmatory spirometry. In 2005, we completed the Austrian Burden of Obstructive Lung Disease-study in 1258 subjects aged >40 years. Post-bronchodilator spirometry was performed, and non-reversible airflow limitation defined by FEV 1 /FVC ratio below the lower limit of normal. Questions from the Salzburg chronic obstructive pulmonary disease screening-questionnaire were selected using a logistic regression model, and risk scores were based on regression-coefficients. A training sub-sample (n = 800) was used to create the score, and a test sub-sample (n = 458) was used to test it. In 2008, an external validation study was done, using the same protocol in 775 patients from primary care. The Salzburg chronic obstructive pulmonary disease screening questionnaire was composed of items related to "breathing problems", "wheeze", "cough", "limitation of physical activity", and "smoking". At the >=2 points cut-off of the Salzburg chronic obstructive pulmonary disease screening questionnaire, sensitivity was 69.1% [95%CI: 56.6%; 79.5%], specificity 60.0% [95%CI: 54.9%; 64.9%], the positive predictive value 23.2% [95%CI: 17.7%; 29.7%] and the negative predictive value 91.8% [95%CI: 87.5%; 95.7%] to detect post bronchodilator airflow limitation. The external validation study in primary care confirmed these findings. The Salzburg chronic obstructive pulmonary disease screening questionnaire was derived from the highly standardized Burden of Obstructive Lung Disease study. This validated and easy to use questionnaire can help to increase the efficiency of chronic obstructive pulmonary disease case-finding. QUESTIONNAIRE FOR PRE-SCREENING POTENTIAL SUFFERERS: Scientists in Austria have developed a brief, simple questionnaire to identify patients likely to have early-stage chronic lung disease. Chronic obstructive pulmonary disease (COPD) is notoriously difficult to diagnose, and the condition often causes irreversible lung damage before it is identified. Finding a simple, cost-effective method of pre-screening patients with suspected early-stage COPD could potentially improve treatment responses and limit the burden of extensive lung function ('spirometry') tests on health services. Gertraud Weiss at Paracelsus Medical University, Austria, and co-workers have developed and validated an easy-to-use, self-administered questionnaire that could prove effective for pre-screening patients. The team trialed the five-point Salzburg COPD-screening questionnaire on 1258 patients. Patients scoring 2 points or above on the questionnaire underwent spirometry tests. The questionnaire seems to provide a sensitive and cost-effective way of pre-selecting patients for spirometry referral.

Chronic Obstructive Pulmonary Disease and Off-Pump Coronary Surgery.

To determine to what extent chronic obstructive pulmonary disease (COPD) affects mortality and morbidity rates in patients treated with off-pump coronary artery bypass graft (CABG). A total of 321 patients treated with off-pump CABG were included in the present study. Of the 321 patients, 46 patients had COPD and they were designated as Group 1 and the remaining 275 patients did not have COPD and they were considered as Group 2. We compared the data obtained from the patients in both groups. While preoperative spirometry values and arterial blood gas oxygen saturation levels were significantly lower, the partial values of carbon dioxide were higher in Group 1. Likewise, extubation time, the amount of drainage and blood transfusion, inotropic support, prolonged intubation, pulmonary complications, the use of bronchodilators, and steroids were statistically higher in Group 1 when compared with Group 2. Overall, there was no marked difference between the two groups in terms of mortality incidence. We found similar morbidity and mortality rates among the patients with COPD and without COPD when they were treated with off-pump CABG. Therefore, the present results indicate that the presence of COPD is not associated with in-hospital mortality or severe morbidity post-CABG by off-pump approach.

Pulmonary endarterectomy: the potentially curative treatment for patients with chronic thromboembolic pulmonary hypertension.

PubMed

Jenkins, David

2015-06-01

Pulmonary endarterectomy (PEA) is the treatment of choice to relieve pulmonary artery obstruction in patients with chronic thromboembolic pulmonary hypertension (CTEPH). It is a complex surgical procedure with a simple principle: removal of obstructive thromboembolic material from the pulmonary arteries in order to reduce pulmonary vascular resistance, relieve pulmonary hypertension (PH) and alleviate right ventricular dysfunction. In the majority of patients there is symptomatic and prognostic benefit. However, not all patients with CTEPH are suitable for treatment with PEA. Operability assessment is not always easy, being largely subjective and based on experience. It is therefore important that all patients are referred to an experienced CTEPH centre for careful evaluation of suitability for surgery. The most common reason for inoperability is distal vasculopathy accounting for a high proportion of the vascular resistance. Surgery requires cardiopulmonary bypass and periods of deep hypothermic circulatory arrest. Complications include reperfusion lung injury and persistent PH. However, with careful patient selection, surgical technique and post-operative management, PEA is a highly effective treatment with mortality rates <5% at experienced centres. Patients who are unsuitable for surgery may be candidates for medical therapy. Copyright ©ERS 2015.

The World Health Organization has estimated that by 2030, chronic obstructive pulmonary disease will be the third leading cause of death worldwide. Most knowledge of chronic obstructive pulmonary disease is based on studies performed in Europe or North America and little is known about the prevalence, patient characteristics and change in lung function over time in patients in developing countries, such as those of Latin America. This lack of knowledge is in sharp contrast to the high levels of tobacco consumption and exposure to biomass fuels exhibited in Latin America, both major risk factors for the development of chronic obstructive pulmonary disease. Studies have also demonstrated that most Latin American physicians frequently do not follow international chronic obstructive pulmonary disease diagnostic and treatment guidelines. The PRISA Study will expand the current knowledge regarding chronic obstructive pulmonary disease and risk factors in Argentina, Chile and Uruguay to inform policy makers and health professionals on the best policies and practices to address this condition. PRISA is an observational, prospective cohort study with at least four years of follow-up. In the first year, PRISA has employed a randomized three-staged stratified cluster sampling strategy to identify 6,000 subjects from Marcos Paz and Bariloche, Argentina, Temuco, Chile, and Canelones, Uruguay. Information, such as comorbidities, socioeconomic status and tobacco and biomass exposure, will be collected and spirometry, anthropometric measurements, blood sampling and electrocardiogram will be performed. In year four, subjects will have repeat measurements taken. There is no longitudinal data on chronic obstructive pulmonary disease incidence and risk factors in the southern cone of Latin America, therefore this population-based prospective cohort study will fill knowledge gaps in the prevalence and incidence of chronic obstructive pulmonary disease, patient characteristics and changes in lung function over time as well as quality of life and health care resource utilization. Information gathered during the PRISA Study will inform public health interventions and prevention practices to reduce risk of COPD in the region.

Chronic lower airway diseases, including chronic obstructive pulmonary disease (COPD) and asthma, are currently the third leading cause of death in the United States. We aimed to evaluate changes in prevalence of and risk factors for COPD and asthma among the US adult population. We evaluated changes in prevalence of self-reported doctor-diagnosed COPD (i.e. chronic bronchitis and emphysema) and asthma and self-reported respiratory symptoms comparing data from the 1988–1994 and 2007–2010 National Health and Nutrition Examination Surveys. To investigate changes in the severity of each outcome over the two periods, we calculated changes in the proportions of spirometry-based airflow obstruction for each outcome. Prevalence of doctor-diagnosed chronic bronchitis and emphysema decreased significantly mainly among males, while asthma increased only among females. The self-reported disease and the respiratory symptoms were associated with increased prevalence of airflow obstruction for both periods. However, the prevalence of airflow obstruction decreased significantly in the second period among those with shortness of breath and doctor-diagnosed respiratory conditions (chronic bronchitis, emphysema, and asthma). COPD outcomes and asthma were associated with lower education, smoking, underweight and obesity, and occupational dusts and fumes exposure. Chronic lower airway diseases continue to be major public health problems. However, decreased prevalence of doctor-diagnosed chronic bronchitis and emphysema (in males) and decreased prevalence of airflow obstruction in those with respiratory symptoms and doctor-diagnosed respiratory diseases may indicate a declining trend and decrease in disease severity between the two periods. Continued focus on prevention of these diseases through public health interventions is prudent. PMID:25540134

Pulmonary hypertension in chronic obstructive pulmonary disease and interstitial lung diseases.

Pulmonary hypertension (PH) is a common complication of chronic respiratory diseases and particularly of chronic obstructive pulmonary disease (COPD) and interstitial lung diseases (ILD). Owing to its frequency COPD is by far the most common cause of PH. It is generally a mild to moderate PH, pulmonary artery mean pressure (PAP) usually ranging between 20 and 25 mm Hg, but PH may worsen during exercise, sleep, and particularly during exacerbations of the disease. These acute increases in PAP may lead to the development of right heart failure. A small proportion of COPD patients may present "disproportionate" PH defined by a resting PAP >35 to 40 mm Hg. The prognosis is particularly poor in these patients. PH is relatively frequent in advanced ILD and particularly in idiopathic pulmonary fibrosis. As in COPD the diagnosis is suggested by Doppler echocardiography, but the confirmation still requires right heart catheterization. As in COPD, functional (alveolar hypoxia) and morphological factors (vascular remodeling, destruction of the pulmonary parenchyma) explain the elevation of pulmonary vascular resistance that leads to PH. Also as in COPD PH is most often mild to moderate. In ILD the presence of PH predicts a poor prognosis. The treatment of PH relies on long-term oxygen therapy. "New" vasodilator drugs have rarely been used in COPD and ILD patients exhibiting severe PH. In advanced ILD the presence of PH is a supplemental argument for considering lung transplantation.

Asthma and chronic obstructive pulmonary disease are preventable and treatable chronic airway diseases with high incidence and prevalence. Pharmacists and clinical pharmacy based pharmaceutical care services have positive impact on therapy outcomes. The aim of this study is to describe drug related problems in a cohort of patients with asthma and chronic obstructive pulmonary disease and to assess interventions provided by the pharmacist to address these problems in a community pharmacy. Study population consisted of patients with asthma and chronic obstructive pulmonary disease older than 18 years who visited the study pharmacy during the pre-determined six-month period. The patients whose disease control states were "not fully controlled" were included in our study for further steps. On the first interview, present and potential drug related problems were addressed, interventions were provided. Follow-up interviews were held one month and two months later than the first interview. For the 44 patients with asthma, 59 drug-related problems and 134 causes for these problems were identified. Eighty-four interventions were made to resolve the problems; and 54.2% of the problems were resolved. For the 37 patients with chronic obstructive pulmonary disease, 60 drug-related problems and 128 causes for these problems were identified. Ninety-five interventions were made to resolve the problems; and 63.3% of the problems were resolved. Pharmacists taking part in therapy and management of asthma and chronic obstructive pulmonary disease can help patients be more educated about their disease and medications; and improve disease control and therapy outcomes.

Chronic obstructive pulmonary disease (COPD) is one of the most important causes of morbidity and mortality worldwide. The complications of COPD are numerous, and cognitive impairment is one of the most common complications that relates to mortality and morbidity directly. The present study was conducted with the aim of evaluating the prevalence of cognitive impairment in patients with COPD in comparison to normal individuals. In this case-control study, 87 patients with COPD, whose diagnoses were confirmed by a pulmonologist based on the spirometry test findings, were included. The mini-mental state examination (MMSE) questionnaire was administered for assessing the cognitive impairment. Arterial oxygen saturation was measured. The MMSE questionnaires were administered to 60 healthy, age-and-sex-matched individuals without a history of myocardial infarction or cerebrovascular infarction, and their arterial oxygen saturations were measured. The data were analyzed using the SPSS (version 20) software. In the case group, 42 patients (48.27%) had no cognitive impairment, 39 (44.82%) had mild, and 6 (6.89%) had moderate cognitive impairment. In the control group, 38 (63.33%) had no cognitive impairment, 20 (33.33%) mild and 2 (3.33 %) moderate cognitive impairment. There were significant relationships between the cognitive impairment and arterial oxygen saturation, severity of COPD, and higher age. The prevalence of cognitive impairment was 51.71% in the case group and 36.66% in the control group. According the results of the present study, COPD increased the risk of cognitive impairment significantly and is related to the severity of COPD, arterial oxygen saturation, and higher age.

AIM: To determine long-term outcomes of surgical treatments for patients with constipation and features of colonic pseudo-obstruction. METHODS: Consecutive 42 patients who underwent surgery for chronic constipation within the last 13 years were prospectively collected. We identified a subgroup with colonic pseudo-obstruction (CPO) features, with dilatation of the colon proximal to the narrowed transitional zone, in contrast to typical slow-transit constipation (STC), without any dilated colonic segments. The outcomes of surgical treatments for chronic constipation with features of CPO were analyzed and compared with outcomes for STC. RESULTS: Of the 42 patients who underwent surgery for constipation, 33 patients had CPO with dilatation of the colon proximal to the narrowed transitional zone. There were 16 males and 17 females with a mean age of 51.2 ± 16.1 years. All had symptoms of chronic intestinal obstruction, including abdominal distension, pain, nausea, or vomiting, and the mean duration of symptoms was 67 mo (range: 6-252 mo). Preoperative defecation frequency was 1.5 ± 0.6 times/wk (range: 1-2 times/wk). Thirty-two patients underwent total colectomy, and one patient underwent diverting transverse colostomy. There was no surgery-related mortality. Postoperative histologic examination showed hypoganglionosis or agangliosis in 23 patients and hypoganglionosis combined with visceral neuropathy or myopathy in 10 patients. In contrast, histology of STC group revealed intestinal neuronal dysplasia type B (n = 6) and visceral myopathy (n = 3). Early postoperative complications developed in six patients with CPO; wound infection (n = 3), paralytic ileus (n = 2), and intraabdominal abscess (n = 1). Defecation frequencies 3 mo after surgery improved to 4.2 ± 3.2 times/d (range: 1-15 times/d). Long-term follow-up (median: 39.7 mo) was available in 32 patients; all patients had improvements in constipation symptoms, but two patients needed intermittent medication for management of diarrhea. All 32 patients had distinct improvements in constipation symptoms (with a mean bowel frequency of 3.3 ± 1.3 times/d), social activities, and body mass index (20.5 kg/m2 to 22.1 kg/m2) and were satisfied with the results of their surgical treatment. In comparison with nine patients who underwent colectomy for STC without colon dilatation, those in the CPO group had a lower incidence of small bowel obstructions (0% vs 55.6%, P < 0.01) and less difficulty with long-distance travel (6.7% vs 66.7%, P = 0.007) on long-term follow-up. CONCLUSION: Chronic constipation patients with features of CPO caused by narrowed transitional zone in the left colon had favorable outcomes after total colectomy. PMID:22969211

Computed Tomographic Airway Morphology in Chronic Obstructive Pulmonary Disease. Remodeling or Innate Anatomy?

PubMed

Diaz, Alejandro A; Estépar, Raul San José; Washko, George R

2016-01-01

Computed tomographic measures of central airway morphology have been used in clinical, epidemiologic, and genetic investigation as an inference of the presence and severity of small-airway disease in smokers. Although several association studies have brought us to believe that these computed tomographic measures reflect airway remodeling, a careful review of such data and more recent evidence may reveal underappreciated complexity to these measures and limitations that prompt us to question that belief. This Perspective offers a review of seminal papers and alternative explanations of their data in the light of more recent evidence. The relationships between airway morphology and lung function are observed in subjects who never smoked, implying that native airway structure indeed contributes to lung function; computed tomographic measures of central airways such as wall area, lumen area, and total bronchial area are smaller in smokers with chronic obstructive pulmonary disease versus those without chronic obstructive pulmonary disease; and the airways are smaller as disease severity increases. The observations suggest that (1) native airway morphology likely contributes to the relationships between computed tomographic measures of airways and lung function; and (2) the presence of smaller airways in those with chronic obstructive pulmonary disease versus those without chronic obstructive pulmonary disease as well as their decrease with disease severity suggests that smokers with chronic obstructive pulmonary disease may simply have smaller airways to begin with, which put them at greater risk for the development of smoking-related disease.

Background Pancreatic pseudocysts arise mostly in patients with alcohol induced chronic pancreatitis causing various symptoms and complications. However, data on the optimal management are rare. To address this problem, we analysed patients with pancreatic pseudocysts treated at our clinic retrospectively. Methods We searched our clinical database for the diagnosis pancreatitis from 2004 till 2014, selected patients with pseudocysts larger than 10 mm and entered all relevant information in a database for statistical analysis. Results In total, 129 patients with pancreatic pseudocysts were treated at our institution during the study period. Most patients suffered from alcohol induced chronic pancreatitis (43.4%; 56/129). Pseudocysts were more frequent in female than in male (2:1) and were mainly located in the pancreatic head (47.3%; 61/129). Local complications like obstructive jaundice were associated with the diameter of the cysts (AUC 0.697 in ROC-curve analysis). However, even cysts up to a diameter of 160 mm can regress spontaneously. Besides a lower re-intervention rate in surgically treated patients, endoscopic, percutaneous and surgical drainage are equally effective. Most treatment related complications occur in large pseudocysts located in the pancreatic head. Conclusion Conservative management of large pseudocysts is successful in many patients. Therefore, indication for treatment should be made carefully considering the presence and risk of local complications. Endoscopic and surgical drainage are equally effective. PMID:28877270

Management of Acute Exacerbation of Asthma and Chronic Obstructive Pulmonary Disease in the Emergency Department.

Acute asthma and chronic obstructive pulmonary disease (COPD) exacerbations are the most common respiratory diseases requiring emergent medical evaluation and treatment. Asthma and COPD are chronic, debilitating disease processes that have been differentiated traditionally by the presence or absence of reversible airflow obstruction. Asthma and COPD exacerbations impose an enormous economic burden on the US health care budget. In daily clinical practice, it is difficult to differentiate these 2 obstructive processes based on their symptoms, and on their nearly identical acute treatment strategies; major differences are important when discussing anatomic sites involved, long-term prognosis, and the nature of inflammatory markers.

Obstructive pulmonary disease includes asthma, chronic obstructive pulmonary disease (COPD; i.e., pulmonary emphysema and chronic bronchitis), bronchiectasis, and cystic fibrosis (CF). It represents a leading cause of death in developed countries. Both familial clustering of non-CF obstructive pulmonary disease and familial aggregation of impaired lung function have been described. This suggests that genetic factors contribute to non-CF obstructive pulmonary disease, even if it is difficult to determine the relative contribution of environmental factors. 11 refs., 1 tab.

Background In response to the escalating burden of chronic illness in Australia, recent health policies have emphasised the promotion of patient self-management and better preventive care. A notable omission from these policies is the acknowledgment that patients with chronic illness tend to have co-morbid conditions. Our objectives were: to identify the common challenges co-morbidity poses to patients and carers in their experiences of self-management; to detail the views and perceptions of health professionals about these challenges; and to discuss policy options to improve health care for people with co-morbid chronic illness. The method included semi-structured interviews and focus groups with 129 purposively sampled participants. Participants were people with Type 2 diabetes, chronic obstructive pulmonary disease and/or chronic heart failure as well as carers and health care professionals. Content analysis of the interview data was conducted using NVivo7 software. Results Patients and their carers found co-morbidity influenced their capacity to manage chronic illness in three ways. First, co-morbidity created barriers to patients acting on risk factors; second, it complicated the process of recognising the early symptoms of deterioration of each condition, and third, it complicated their capacity to manage medication. Conclusion Findings highlight challenges that patients with multiple chronic conditions face in relation to preventive care and self-management. Future clinical policy initiatives need to move away from single illness orientation toward strategies that meet the needs of people with co-morbid conditions and strengthen their capacity to self-manage. These patients will benefit directly from specialised education and services that cater to the needs of people with clusters of co-morbidities. PMID:19735576

Air plethysmography (APG) is a functional, noninvasive test that can assess volumetric changes in the lower limb and might therefore be used as a diagnostic tool in chronic deep venous disease. However, use of APG in chronic deep venous obstructive disease remains debatable. This study assessed the clinical value of APG in identifying chronic deep venous obstruction. All patients referred to our tertiary, outpatient clinic between January 2011 and August 2013 with chronic venous complaints and suspected outflow obstruction underwent an outflow fraction (OF), ejection fraction (EF), and residual volume fraction (RVF) test using APG. Duplex ultrasound and magnetic resonance venography were used to establish whether and where obstruction was present. Diagnostic values of these tests were assessed for obstructions at different levels of the deep venous system. A total of 312 limbs in 248 patients were tested. Mean age was 45.5 ± 14.0 years, and 62.5% were female. In post-thrombotic disease, specificity and positive predictive value for OF were as high as 98.4% and 95.0%, respectively; however, sensitivity was 34.8% and negative predictive value was 29.6%, with no clinically relevant positive or negative likelihood ratios. No clinically relevant differences were observed in stratifying for level of obstruction. EF and RVF were as inconclusive. Neither could these parameters be used in diagnosing nonthrombotic iliac vein compression. We found a poor correlation between OF, EF, or RVF, determined by APG, and the presence of chronic deep venous obstruction. Therefore, use of its relative parameters is unwarranted in daily clinical practice. Copyright © 2016 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

Bronchiectasis and Aspergillus: How are they linked?

PubMed

De Soyza, Anthony; Aliberti, Stefano

2017-01-01

Bronchiectasis is a chronic airway infection syndrome, distinct from cystic fibrosis that is rising in prevalence and is associated with significant morbidity and mortality. It can be caused by many etiologies including post-infectious effects or be seen in common lung diseases such as chronic obstructive pulmonary disease (COPD) or severe asthma. Bronchiectasis is associated with many Aspergillus-associated syndromes: allergic bronchopulmonary aspergillosis (ABPA) may complicate asthma, thus leading to bronchiectasis as part of the diagnostic criteria of ABPA or can complicate preexisting bronchiectasis due to another etiology. Aspergilloma can develop in areas of lung damage seen in patients with bronchiectasis, whereas fungal bronchitis may lead to later bronchiectasis. Invasive aspergillosis, perhaps more commonly viewed as a consequence of significant immunosuppression, is also seen in the absence of immunosuppression in those with underlying lung diseases including bronchiectasis. The pathogenesis and treatments of these diverse Aspergillus-associated diseases in bronchiectasis are discussed. © The Author 2016.

Objectives/Hypothesis Nasal surgery has been implicated to improve continuous positive airway pressure (CPAP) compliance in patients with obstructive sleep apnea (OSA) and nasal obstruction. However, the cost-effectiveness of nasal surgery to improve CPAP compliance is not known. We modeled the cost-effectiveness of two types of nasal surgery versus no surgery in patients with OSA and nasal obstruction undergoing CPAP therapy. Study Design Cost-effectiveness decision tree model. Methods We built a decision tree model to identify conditions under which nasal surgery would be cost-effective to improve CPAP adherence over the standard of care. We compared turbinate reduction and septoplasty to nonsurgical treatment over varied time horizons from a third-party payer perspective. We included variables for cost of untreated OSA, surgical cost and complications, improved compliance postoperatively, and quality of life. Results Our study identified nasal surgery as a cost-effective strategy to improve compliance of OSA patients using CPAP across a range of plausible model assumptions regarding the cost of untreated OSA, the probability of adherence improvement, and a chronic time horizon. The relatively lower surgical cost of turbinate reduction made it more cost-effective at earlier time horizons, whereas septoplasty became cost-effective after a longer timespan. Conclusions Across a range of plausible values in a clinically relevant decision model, nasal surgery is a cost-effective strategy to improve CPAP compliance in OSA patients with nasal obstruction. Our results suggest that OSA patients with nasal obstruction who struggle with CPAP therapy compliance should undergo evaluation for nasal surgery. PMID:27653626

Chronic obstructive pulmonary disease and lung cancer are leading causes of death with comparable symptoms at the end of life. Cross-national comparisons of place of death, as an important outcome of terminal care, between people dying from chronic obstructive pulmonary disease and lung cancer have not been studied before. We collected population death certificate data from 14 countries (year: 2008), covering place of death, underlying cause of death, and demographic information. We included patients dying from lung cancer or chronic obstructive pulmonary disease and used descriptive statistics and multivariable logistic regressions to describe patterns in place of death. Of 5,568,827 deaths, 5.8% were from lung cancer and 4.4% from chronic obstructive pulmonary disease. Among lung cancer decedents, home deaths ranged from 12.5% in South Korea to 57.1% in Mexico, while hospital deaths ranged from 27.5% in New Zealand to 77.4% in France. In chronic obstructive pulmonary disease patients, the proportion dying at home ranged from 10.4% in Canada to 55.4% in Mexico, while hospital deaths ranged from 41.8% in Mexico to 78.9% in South Korea. Controlling for age, sex, and marital status, patients with chronic obstructive pulmonary disease were significantly less likely die at home rather than in hospital in nine countries. Our study found in almost all countries that those dying from chronic obstructive pulmonary disease as compared with those from lung cancer are less likely to die at home and at a palliative care institution and more likely to die in a hospital or a nursing home. This might be due to less predictable disease trajectories and prognosis of death in chronic obstructive pulmonary disease. IMPROVING END-OF-LIFE CARE: Structured palliative care similar to that offered to cancer sufferers should be in place for patients with chronic lung disease. Joachim Cohen at Vrije University in Brussels and co-workers examined international death certificate data collected from 14 countries to determine place of death for patients with lung cancer and chronic obstructive pulmonary disease (COPD). While patients with COPD suffer similar symptoms to lung cancer in their final days, few COPD patients receive palliative care or achieve the common wish of dying at home. This may be partly due to the inherent unpredictability of final-stage COPD compared with lung cancer. Cohen's team found that, with the exception of Italy, Spain, and Mexico, patients with COPD were significantly more likely to die in hospital than at home. They highlight the need for improved COPD palliative care provision.

To explore chronic obstructive pulmonary disease patients' experiences with a partnership-based nursing practice programme in the home setting. Patients with chronic obstructive pulmonary disease suffer from psychological and physiological problems, especially when they return home after hospitalisation from exacerbation. Many express a need for information and knowledge about chronic obstructive pulmonary disease. Partnership as practice is a patient-centred framework providing an individualised practice for each patient. This study intends to achieve a nuanced and improved understanding of chronic obstructive pulmonary disease patients' experiences with a partnership-based nursing practice programme comprising home visits from a respiratory nurse after hospital discharge, alongside interdisciplinary collaboration. This study has a qualitative design with interviews. Six individual semi-structured interviews collected in 2012-2013 constitute the material. Interviews were recorded, transcribed to written text and analysed using systematic text condensation. Three key themes were identified: to be seen, talked with and understood; healthcare support at home-continuity, practical support and facilitation; and exchange of knowledge. However, there were two generic themes that permeated the material: feeling safe and comforted, and motivation to achieve better health. Patients with chronic obstructive pulmonary disease can experience feeling safe and comforted, and be motivated to make changes in order to achieve better health after participating in a partnership-based nursing practice programme that includes home visits from a respiratory nurse and interdisciplinary cooperation after hospital discharge. To feel safe is of great importance, and how this relates to the patient's ability to cope with illness should be explored in further research. The results suggest that the partnership-based nursing practice programme that includes home visits and interdisciplinary collaboration can be a good approach to meeting the complexity of the chronic obstructive pulmonary disease patient's health needs. © 2017 John Wiley & Sons Ltd.

Influenza and pneumococcal vaccinations are recommended in chronic obstructive pulmonary disease patients to decrease associated risks at all stages. Although the prevalence of chronic obstructive pulmonary disease is high in our country, as previously reported, vaccination rates are low. To assess the vaccination rates of chronic obstructive pulmonary disease patients and factors that may affect these. Multi-centre cross-sectional study. Patients admitted to the chest diseases clinics of six different centres between 1 February 2013 and 1 January 2014 with a pre-diagnosis of Chronic obstructive pulmonary disease according to the Global initiative for chronic obstructive lung disease criteria, who were in a stable condition were included in the study. The survey, which included demographic characteristics, socio-economic status, severity of disease and vaccination information, was first tested on a small patient population before the study. The survey was completed by the investigators after obtaining written informed consent. The average age of the 296 included patients was 66.3±9.3 years and 91.9% were male. Of these, 36.5% had the influenza vaccination and 14.1% had the pneumococcal vaccination. The most common reason for not being vaccinated was 'no recommendation by doctors': 57.2% in the case of influenza vaccinations, and 46.8% in the case of pneumococcal vaccinations. Both vaccination rates were significantly higher in those patients with comorbidities (influenza vaccination p<0.001; pneumococcal vaccination p=0.06). There was no significant correlation with age, gender, smoking and severity of disease (p>0.05). Vaccination rates were significantly higher in those with a white-collar occupation and higher education level, and who presented to a university hospital (p<0.001). Medical professionals do not request vaccinations as often as the International Guidelines suggest for chronic obstructive pulmonary disease patients. Awareness of the importance of these vaccinations among both doctors and patients needs to be addressed.

Beta 2 agonists reduce airway hypersensitivity to bronchoconstrictor stimuli acutely in patients with asthma and chronic obstructive lung disease. To determine whether these drugs also protect against excessive airway narrowing, the effect of inhaled salbutamol on the position and shape of the dose-response curves for histamine or methacholine was investigated in 12 patients with asthma and 11 with chronic obstructive lung disease. After pretreatment with salbutamol (200 or 400 micrograms) or placebo in a double blind manner dose-response curves for inhaled histamine and methacholine were obtained by a standard method on six days in random order. Airway sensitivity was defined as the concentration of histamine or methacholine causing a 20% fall in FEV1 (PC20). A maximal response plateau on the log dose-response curve was considered to be present if two or more data points for FEV1 fell within a 5% response range. In the absence of a plateau, the test was continued until a predetermined level of severe bronchoconstriction was reached. Salbutamol caused an acute increase in FEV1 (mean increase 11.5% predicted in asthma, 7.2% in chronic obstructive lung disease), and increase in PC20 (mean 15 fold in asthma, fivefold in chronic obstructive lung disease), and an increase in the slope of the dose-response curves in both groups. In subjects in whom a plateau of FEV1 response could be measured salbutamol did not change the level of the plateau. In subjects without a plateau salbutamol did not lead to the development of a plateau, despite achieving a median FEV1 of 44% predicted in asthma and 39% in chronic obstructive lung disease. These results show that, although beta 2 agonists acutely reduce the airway response to a given strength of bronchoconstrictor stimulus, they do not protect against excessive airflow obstruction if there is exposure to relatively strong stimuli. This, together with the steepening of the dose-response curve, could be a disadvantage of beta 2 agonists in the treatment of moderate and severe asthma or chronic obstructive lung disease.

We aimed to study sleep problems in hospitalized chronic obstructive pulmonary disease patients and assess the relationship of sleep quality with mental health and demographics of patients. Our study sample consisted of 850 chronic obstructive pulmonary disease patients hospitalized in Masih Daneshvari Hospital. Demographic data were collected and the Pittsburgh Sleep Quality and mental health questionnaires were filled out for patients. The results showed that 5.9 percent were suffering from severe sleep problems, while 4.7 percent had severe mental problems. A strong positive correlation was found between the total scores of mental health and sleep quality ( p < 0.01). The prevalence of sleep and mental health problems was higher in females compared to males. Mental health and sleep quality play important roles in quality of life of chronic obstructive pulmonary disease patients.

This study investigated the effects of illness perceptions and coping with disease on health-related quality of life in chronic obstructive pulmonary disease. Therefore, participants ( N = 444) completed online questionnaires assessing illness severity (chronic obstructive pulmonary disease stage), Illness Perceptions Questionnaire, coping with disease (Essener Coping Questionnaire), and health-related quality of life (short form-12). Hierarchical regression and moderation analyses were conducted. The results showed that health-related quality of life was predicted by illness perceptions and several aspects of coping with disease. The association between illness perceptions and health-related quality of life was mediated by the corresponding coping with disease subscales. It is concluded that in order to prevent decreasing health-related quality of life in chronic obstructive pulmonary disease, treatment may be adjusted by promoting coping with disease and functional illness perceptions.

Chronic pancreatitis (CP) is a painful, yet benign inflammatory process of the pancreas. Surgical management should be individualized because the pain is multifactorial and its mechanisms vary from patient to patient. Two main pathogenetic theories for the mechanisms of pain in CP have been proposed: the neurogenic theory and the theory of increased intraductal/intraparenchymal pressures. The latter theory is strongly supported by the good results of drainage procedures in the surgical management of CP. Other possible contributing factors include pancreatic ischemia; a centrally sensitized pain state; and the development of complications, such as pseudocysts and stenosis of the duodenum or common bile duct. Common indications for surgery include intractable pain, suspicion of neoplasm, and complications that cannot be resolved with radiological or endoscopic treatments. Operative procedures have been historically classified into 4 categories: decompression procedures for diseased and obstructed pancreatic ducts; resection procedures for the proximal, distal, or total pancreas; denervation procedures of the pancreas; and hybrid procedures. Pancreaticoduodenectomy and pylorus-preserving pancreaticoduodenectomy, once the standard operations for patients with CP, have been replaced by hybrid procedures, such as duodenum-preserving pancreatic head resection, the Frey procedure, and their variants. These procedures are safe and effective in providing long-term pain relief and in treating CP-related complications. Hybrid procedures should be the operations of choice for patients with CP.

Outpatient Chronic Obstructive Pulmonary Disease Management: Going for the GOLD.

Bellinger, Christina R; Peters, Stephen P

2015-01-01

Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the United States with a burden of $50 billion in direct health care costs. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) defines airflow obstruction as spirometry where the ratio of forced expiratory volume in the first second to forced vital capacity after bronchodilation is less than 0.70. The guidelines also provided graded recommendations on current therapy for COPD. Treatment can be guided based on severity of disease and severity of symptoms. We review the GOLD guidelines to provide an overview of treatment modalities aimed at improving lung function, reducing hospitalization, and reducing mortality.

Kugler, Christian; Stanzel, Franz

Tracheomalacia is excessive collapsibility of the trachea, typically during expiration. Congenital forms are associated with severe symptoms. Milder forms often present after the neonatal period. Adult malacia is mostly associated with chronic obstructive pulmonary disease. Functional bronchoscopy is still not standardized. Dynamic airway CT is a promising tool for noninvasive diagnosis. Bronchoscopy and stent insertion lead to significant improvement, but with a high complication rate. Surgical lateropexia, tracheal resection, and surgical external stabilization are options. Tracheoplasty seems to be the best choice for selected cases of adult malacia. The most commonly performed surgery in children is aortopexy. Copyright © 2014 Elsevier Inc. All rights reserved.

It is established, that joining "Mildrocard" to complex therapy associated to pathology promotes reduction clinical display of heart failure, shows cardioprotective and pulmoprotective effects.

Early fiberoptic bronchoscopy during non-invasive ventilation in patients with decompensated chronic obstructive pulmonary disease due to community-acquired-pneumonia

PubMed Central

2010-01-01

Introduction Inefficient clearance of copious respiratory secretion is a cause of non-invasive positive pressure ventilation (NPPV) failure, especially in chronic respiratory patients with community-acquired-pneumonia (CAP) and impaired consciousness. We postulated that in such a clinical scenario, when intubation and conventional mechanical ventilation (CMV) are strongly recommended, the suction of secretions with fiberoptic bronchoscopy (FBO) may increase the chance of NPPV success. The objective of this pilot study was, firstly, to verify the safety and effectiveness of early FBO during NPPV and, secondly, to compare the hospital outcomes of this strategy versus a CMV-based strategy in patients with decompensated chronic obstructive pulmonary disease (COPD) due to CAP who are not appropriate candidates for NPPV because of inefficient mucous clearance and hypercapnic encephalopathy (HE). Methods This is a 12-month prospective matched case-control study performed in one respiratory semi-intensive care unit (RSICU) with expertise in NPPV and in one intensive care unit (ICU). Fifteen acutely decompensated COPD patients with copious secretion retention and HE due to CAP undergoing NPPV in RSICU, and 15 controls (matched for arterial blood gases, acute physiology and chronic health evaluation score III, Kelly-Matthay scale, pneumonia extension and severity) receiving CMV in the ICU were studied. Results Two hours of NPPV significantly improved arterial blood gases, Kelly and cough efficiency scores without FBO-related complications. NPPV avoided intubation in 12/15 patients (80%). Improvement in arterial blood gases was similar in the two groups, except for a greater PaO2/fraction of inspired oxygen ratio with CMV. The rates of overall and septic complications, and of tracheostomy were lower in the NPPV group (20%, 20%, and 0%) versus the CMV group (80%, 60%, and 40%; P < 0.05). Hospital mortality, duration of hospitalisation and duration of ventilation were similar in the two groups. Conclusions In patients with decompensated COPD due to CAP who are candidates for CMV because of HE and inability to clear copious secretions, NPPV with early therapeutic FBO performed by an experienced team is a feasible, safe and effective alternative strategy.

The self-expandable metallic stent (SEMS) is an excellent non-invasive tool for emergent bowel obstruction. This study was designed to evaluate the clinical usefulness of the SEMS for avoiding perioperative complications. We analyzed a total of 47 consecutive patients who had a bowel obstruction due to colorectal cancer at initial diagnosis between 2012 and 2017 from hospital records. Perioperative complications occurred in 30% (14/47) of patients. Univariate and multivariate logistic regression analyses identified an age of more than 75 years [p=0.037, OR=6.84 (95% CI=1.11-41.6)] and the absence of an SEMS treatment [p=0.028, OR=18.5 (95% CI=1.36-250.0)] as independent risk factors for perioperative complications. Pneumonia (12.7% (6/47)) was the most common complication. There were no pneumonia patients (0% (0/15)) who were treated with the SEMS. In contrast to patients with the non-SEMS treatment, 18.7% (6/32) of all patients and 35.7% (5/14) of elderly patients had pneumonia. The SEMS is a safe and effective treatment for avoiding perioperative complications, particularly pneumonia, and may be a crucial strategy in elderly patients with acute obstruction due to colorectal cancer.

The impact of residual pulmonary obstruction on the outcome of patients with pulmonary embolism is uncertain.We recruited 647 consecutive symptomatic patients with a first episode of pulmonary embolism, with or without concomitant deep venous thrombosis. They received conventional anticoagulation, were assessed for residual pulmonary obstruction through perfusion lung scanning after 6 months and then were followed up for up to 3 years. Recurrent venous thromboembolism and chronic thromboembolic pulmonary hypertension were assessed according to widely accepted criteria.Residual pulmonary obstruction was detected in 324 patients (50.1%, 95% CI 46.2-54.0%). Patients with residual pulmonary obstruction were more likely to be older and to have an unprovoked episode. After a 3-year follow-up, recurrent venous thromboembolism and/or chronic thromboembolic pulmonary hypertension developed in 34 out of the 324 patients (10.5%) with residual pulmonary obstruction and in 15 out of the 323 patients (4.6%) without residual pulmonary obstruction, leading to an adjusted hazard ratio of 2.26 (95% CI 1.23-4.16).Residual pulmonary obstruction, as detected with perfusion lung scanning at 6 months after a first episode of pulmonary embolism, is an independent predictor of recurrent venous thromboembolism and/or chronic thromboembolic pulmonary hypertension.

Type I thyroplasty has become a primary surgical choice for voice restoration in patients with glottal incompetence. This study examines factors associated with laryngeal complications after type I thyroplasty. Ten laryngoscopic variables were analyzed from preoperative, intraoperative, and postoperative videolaryngoscopies of 51 patients undergoing 58 medialization procedures. Ten patient and operative variables were examined by medical record review. Major complications were defined as wound hemorrhage, airway obstruction, or prosthesis extrusion. Minor complications were defined as vocal fold hematoma without airway obstruction or prosthesis movement. The major complication rate was 8.6%, and the minor complication rate was 29%. No delayed hemorrhage or airway obstruction occurred. Prosthesis extrusion occurred in five (8.6%) patients 1 week to 5 months after surgery. Extrusion was associated with suboptimal prosthesis placement in 80% of cases. Two patients retained excellent glottal closure despite extrusion. Vocal fold hematoma was identified in 14 (24%) cases and resolved within 1 week. Prosthesis movement occurred in three (5%) patients 1 week to 6 months after surgery and resulted in poor glottal closure. All patients with prosthesis extrusion or movement were female. Type I thyroplasty remains a safe outpatient procedure with few major complications. Prosthesis extrusion was associated with suboptimal prosthesis placement and may or may not result in poor glottal closure. Minor vocal fold hematomas were relatively frequent, resolved rapidly, and were not associated with airway obstruction. Female patients may be more prone to complications because of their small laryngeal size.

Obstructive sleep apnea (OSA) is associated with increased risk for cardiovascular morbidity and mortality. Epidemiological and animal models studies generate hypotheses for innovative strategies in OSA management by interfering intermediates mechanisms associated with cardiovascular complications. We have thus initiated the Epigenetics modification in Obstructive Sleep Apnea (EPIOSA) study (ClinicalTrials.gov identifier: NCT02131610). EPIOSA is a prospective cohort study aiming to recruit 350 participants of caucasian ethnicity and free of other chronic or inflammatory diseases: 300 patients with prevalent OSA and 50 non-OSA subjects. All of them will be follow-up for at least 5 years. Recruitment and study visits are performed in single University-based sleep clinic using standard operating procedures. At baseline and at each one year follow-up examination, patients are subjected to a core phenotyping protocol. This includes a standardized questionnaire and physical examination to determine incident comorbidities and health resources utilization, with a primary focus on cardiovascular events. Confirmatory outcomes information is requested from patient records and the regional Department of Health Services. Every year, OSA status will be assessed by full sleep study and blood samples will be obtained for immediate standard biochemistry, hematology, inflammatory cytokines and cytometry analysis. For biobanking, aliquots of serum, plasma, urine, mRNA and DNA are also obtained. Bilateral carotid echography will be performed to assess subclinical atherosclerosis and atherosclerosis progression. OSA patients are treated according with national guidelines. EPIOSA will enable the prospective evaluation of inflammatory and epigenetics mechanism involved in cardiovascular complication of treated and non-treated patients with OSA compared with non OSA subjects.

The study aimed to explore patients' experience of living with chronic obstructive pulmonary disease and their perspective of their community healthcare for chronic obstructive pulmonary disease to extract affective responses in order to develop potential items for a patient-reported experience measure for chronic obstructive pulmonary disease. Qualitative face-face interviews were conducted, in the community, with 64 patients with chronic obstructive pulmonary disease recruited from General Practices and Breathe-Easy community groups in the Outer North East, East and City areas of London and Essex, UK. A two phase analysis of the qualitative data was conducted to identify themes arising from patients' description of living with chronic obstructive pulmonary disease and their perceptions of their community healthcare and subsequently the affective responses underlying the themes raised by patients, which gave emotional colour to the themes, bringing the thematic analysis closer to the subjective patient experience. Five themes were identified from the interview data: 'Journey to diagnosis'; 'Smoking'; 'Usual care'; 'My everyday life'; and 'Exacerbations'. Twenty-one affective responses were identified and categorised as either 'negative', 'positive' or 'bivalent'. 'Frustration', a negative affective response was prevalent in four themes. 'Gratitude', 'hope' and 'happiness/enjoyment' were among the more positive responses more prevalent across several themes. By conducting a novel two-way analysis (thematic and affective) it was possible to identify themes and affective responses that were aligned to those themes. This enabled the development of 38 chronic obstructive pulmonary disease-specific experience items to take forward for further testing including item reduction and validity and reliability in the next stage of the patient-reported experience measure development. GIVING IMPORTANCE TO PATIENTS' EMOTIONS: An exploration of patient perceptions of living with chronic lung disease will help develop a new patient reported experience scale. Healthcare services are aiming to provide effective patient-centered care for those with chronic obstructive pulmonary disease (COPD). Such care strategies require structured, validated patient feedback scales to facilitate accurate communication between patients, carers and healthcare professionals. Susan Walker at Anglia Ruskin University in Chelmsford, UK, and co-workers analyzed qualitative data from interviews with 64 COPD patients in London and Essex regarding their emotions and perceptions of living with COPD, with the aim of creating a patient reported experience measure, or PREM. Initial results identified five themes-including 'journey to diagnosis' and 'everyday life'-and twenty-one affective responses, ranging from negative to positive. The team will take these results forward for further validation.

This study aimed to compare the efficiency of the STOP-BANG and Berlin Obstructive Sleep Apnoea Syndrome questionnaires for evaluating potential respiratory complications during the perioperative period. Questionnaires that are used to determine obstructive sleep apnoea risk are not widely used for surgical patients. Among the questionnaires that are commonly used for obstructive sleep apnoea screening, it remains unclear whether the STOP-BANG or Berlin Obstructive Sleep Apnoea Syndrome questionnaire is more effective in terms of ease of use, usage period and diagnosis of surgical patients with obstructive sleep apnoea risk. This study was designed as a descriptive and prospective study. The study included 126 patients over 18 years of age who were American Society of Anesthesiologists classification class I-II and underwent laparoscopic cholecystectomy. To determine the potential obstructive sleep apnoea syndrome risk, the STOP-BANG and Berlin questionnaires were administered. Respiratory complications were then observed during the perioperative period. During intubation and extubation, we observed statistically significant differences in difficult intubation, difficult facemask ventilation and desaturation frequency between the high- and low-risk groups for obstructive sleep apnoea syndrome, as determined by the STOP-BANG questionnaire. During extubation, statistically significant differences in coughing, breath-holding and desaturation frequency were observed between the high-risk and low-risk groups, according to the Berlin questionnaire. In the post-anaesthesia care unit, both questionnaires found statistically significant differences between the low- and high-risk groups. Obstructive sleep apnoea syndrome screening questionnaires administered during the preoperative period are useful for predicting perioperative respiratory complications. It may be most useful to administer the STOP-BANG questionnaire as the initial evaluation. Questionnaires may be used to determine the risk of obstructive sleep apnoea syndrome, which could impact the anaesthetisation of surgical patients. Questionnaires for determining the risk of obstructive sleep apnoea syndrome should be used regularly for surgical patients, and these questionnaires should be used to improve clinical protocols for anaesthesia and postanaesthesia care. © 2016 John Wiley & Sons Ltd.

Sulfur mustard (SM) is an extremely toxic gas used in chemical warfare to cause massive lung injury and death. Victims exposed to SM gas acutely present with inhalational lung injury, but among those who survive, some develop obstructive airway diseases referred to as SM-lung syndrome. Pathophysiologically, SM-lung shares many characteristics with smoking-induced chronic obstructive pulmonary disease (COPD), including airway remodeling, goblet cell metaplasia, and obstructive ventilation defect. Some of the hallmarks of COPD pathogenesis, which include dysregulated lung inflammation, neutrophilia, recruitment of interleukin 17A (IL -17A) expressing CD4 + T cells (Th17), and the paucity of lung regulatory T cells (Tregs), have also been described in SM-lung. Areas covered: A literature search was performed using the MEDLINE, EMBASE, and Web of Science databases inclusive of all literature prior to and including May 2017. Expert commentary: Here we review some of the recent findings that suggest a role for Th17 cell-mediated inflammatory changes associated with pulmonary complications in SM-lung and suggest new therapeutic approaches that could potentially alter disease progression with immune modulating biologics that can restore the lung Th17/Treg balance.

We sought to develop and externally validate a nomogram and web-based calculator to individually predict the development of serious complications in seemingly stable adult patients with solid tumours and episodes of febrile neutropenia (FN). The data from the FINITE study (n=1133) and University of Salamanca Hospital (USH) FN registry (n=296) were used to develop and validate this tool. The main eligibility criterion was the presence of apparent clinical stability, defined as events without acute organ dysfunction, abnormal vital signs, or major infections. Discriminatory ability was measured as the concordance index and stratification into risk groups. The rate of infection-related complications in the FINITE and USH series was 13.4% and 18.6%, respectively. The nomogram used the following covariates: Eastern Cooperative Group (ECOG) Performance Status ⩾2, chronic obstructive pulmonary disease, chronic cardiovascular disease, mucositis of grade ⩾2 (National Cancer Institute Common Toxicity Criteria), monocytes <200/mm(3), and stress-induced hyperglycaemia. The nomogram predictions appeared to be well calibrated in both data sets (Hosmer-Lemeshow test, P>0.1). The concordance index was 0.855 and 0.831 in each series. Risk group stratification revealed a significant distinction in the proportion of complications. With a ⩾116-point cutoff, the nomogram yielded the following prognostic indices in the USH registry validation series: 66% sensitivity, 83% specificity, 3.88 positive likelihood ratio, 48% positive predictive value, and 91% negative predictive value. We have developed and externally validated a nomogram and web calculator to predict serious complications that can potentially impact decision-making in patients with seemingly stable FN.

To determine whether endogenous carbon monoxide levels in exacerbations of Chronic Obstructive Pulmonary Disease patients were higher compared to healthy individuals and to investigate alteration of carbon monoxide levels across the three different severity stages of Global Initiative for Chronic Obstructive Lung Disease criteria related to Chronic Obstructive Pulmonary Disease exacerbations. The prospective study was conducted from January to March 2011 at two medical institutions in Ankara, Turkey, and comprised patients of acute Chronic Obstructive Pulmonary Disease exacerbations. The severity of the exacerbations was based on the Global Initiative for Chronic Obstructive Lung Disease criteria. Patients with active tobacco smoking, suspicious carbon monoxide poisoning and uncertain diagnosis were excluded. healthy control subjects who did not have any comorbid diseases and smoking habitus were also enrolled to compare the differences between carboxyhaemoglobin levels A two-tailed Mann-Whitney U test with Bonferroni correction was done following a Kruskal-Wallis test for statistical purposes. There were 90 patients and 81 controls in the study. Carboxyhaemoglobin levels were higher in the patients than the controls (p < 0.001). As for the three severity stages, Group 1 had a median carboxyhaemoglobin of 1.6 (0.95- 2.00). The corresponding levels in Group 2 (1.8 [1.38-2.20]) and Group 3 (1.9 [1.5-3.0]) were higher than the controls (p < 0.001 and p < 0.005 respectively). No statistically significant difference between Group 1 and the controls (1.30 [1.10-1.55]) was observed (p < 0.434). Carboxyhaemoglobin levels were significantly higher in exacerbations compared with the normal population. Also, in more serious exacerbations, carboxyhaemoglobin levels were significantly increased compared with healthy individuals and mild exacerbations.

Extrahepatic portal vein obstruction and portal vein thrombosis in special situations: Need for a new classification.

Extrahepatic portal vein obstruction is a vascular disorder of liver, which results in obstruction and cavernomatous transformation of portal vein with or without the involvement of intrahepatic portal vein, splenic vein, or superior mesenteric vein. Portal vein obstruction due to chronic liver disease, neoplasm, or postsurgery is a separate entity and is not the same as extrahepatic portal vein obstruction. Patients with extrahepatic portal vein obstruction are generally young and belong mostly to Asian countries. It is therefore very important to define portal vein thrombosis as acute or chronic from management point of view. Portal vein thrombosis in certain situations such as liver transplant and postsurgical/liver transplant period is an evolving area and needs extensive research. There is a need for a new classification, which includes all areas of the entity. In the current review, the most recent literature of extrahepatic portal vein obstruction is reviewed and summarized.

Benign Prostatic Hyperplasia: from Bench to Clinic

Cho, Hee Ju

Benign prostatic hyperplasia (BPH) is a prevalent disease, especially in old men, and often results in lower urinary tract symptoms (LUTS). This chronic disease has important care implications and financial risks to the health care system. LUTS are caused not only by mechanical prostatic obstruction but also by the dynamic component of obstruction. The exact etiology of BPH and its consequences, benign prostatic enlargement and benign prostatic obstruction, are not identified. Various theories concerning the causes of benign prostate enlargement and LUTS, such as metabolic syndrome, inflammation, growth factors, androgen receptor, epithelial-stromal interaction, and lifestyle, are discussed. Incomplete overlap of prostatic enlargement with symptoms and obstruction encourages focus on symptoms rather than prostate enlargement and the shifting from surgery to medicine as the treatment of BPH. Several alpha antagonists, including alfuzosin, doxazosin, tamsulosin, and terazosin, have shown excellent efficacy without severe adverse effects. In addition, new alpha antagonists, silodosin and naftopidil, and phosphodiesterase 5 inhibitors are emerging as BPH treatments. In surgical treatment, laser surgery such as photoselective vaporization of the prostate and holmium laser prostatectomy have been introduced to reduce complications and are used as alternatives to transurethral resection of the prostate (TURP) and open prostatectomy. The status of TURP as the gold standard treatment of BPH is still evolving. We review several preclinical and clinical studies about the etiology of BPH and treatment options. PMID:22468207

Among the colorectal cancers, the incidence of colon cancer has obviously increased. As a result, the actual incidence of colon cancer has exceeded that of rectal cancer, which dramatically changed the long-existing epidemiological profile. The acute complications of colon cancer include bleeding, obstruction, and perforation, which were among the common acute abdominal surgical conditions. The rapid and accurate diagnosis of these acute complications was very important, and laparoscopic techniques can be applied in abdominal surgery for management of the complications. PMID:25035661

The concurrent diagnosis of chronic obstructive pulmonary disease (COPD) and sleep apnoea-hypopnoea syndrome (SAHS) (overlap syndrome), can contribute to worsening respiratory symptoms, but whether the severity of COPD is associated with co-morbid SAHS is unknown. We investigated whether the severity of COPD is associated with the complication of SAHS by examination of nocturnal oximetry as an alternative to polysomnography. Patients with COPD concurrently completed nocturnal oximetry, pulmonary function tests, a COPD assessment test, an Epworth sleepiness scale and a hospital anxiety and depression scale to evaluate the severity of COPD and possible concurrent presence of SAHS. We retrospectively analysed the data to assess correlation between the oxygen desaturation index (ODI) and each clinical variables and evaluated the predictors of ODI ≥ 15. This study included 103 patients (91 males, 88%) with a mean age of 72 ± 8 years and body mass index of 22 ± 3 kg/m(2). ODI was positively correlated with FEV1, FEV1/FVC and FEV1% predicted, which meant that ODI was inversely correlated with airflow limitation. Univariate logistic regression analysis revealed that FEV1% predicted and FEV1/FVC were predictors of ODI ≥ 15. ODI is inversely correlated with airflow limitation and milder COPD patients may have co-morbid SAHS.

Chronic inflammation is an important process in the pathogenesis of obesity, wherein there is an aberrant ex- pression of genes encoding adipokines. Visceral tissue is characterized by a higher expression and secretion of interleukin-8, interleukin-1ß and plasminogen activator inhibitor 1 in the subcutaneous tissue secretion of leptin prevails. An important complication of obesity is obstructive sleep apnea, often observed in Prader- Willi syndrome. The genetic background of sleep apnea may be a polymorphism of the SREBF1 gene. The consequence of excess body mass is metabolic syndrome, which may be related to the occurrence of the rs926198 variant of gene encoding caveolin-1. The genes of transcription factor TCF7L2 and PPAR-γ2 take part in the pathogenesis of diabetes development. It has been demonstrated that oncogenes FOS, FOSB, and JUN may be co-responsible not only for obesity but also for osteoporosis and colorectal cancer. It has been shown that weight loss causes a modification in the expression of about 100 genes involvedt in the production of substances such as cytokines and other responsible for chronic inflammation in obesity. In future studies on the complications of obesity, such scientific disciplines as proteomics, peptidomics, metabolomics and transcriptomics should be used. The aim of this study is to present the current state of knowledge about the genetic basis of obesity complications.

Coal mine workers are at risk for a range of chronic respiratory diseases including coal workers' pneumoconiosis, diffuse dust-related fibrosis, and chronic obstructive pulmonary disease. The purpose of this review is to describe coal mining processes and associated exposures to inform the diagnostic evaluation of miners with respiratory symptoms. Although rates of coal workers' pneumoconiosis declined after regulations were enacted in the 1970s, more recent data shows a reversal in this downward trend. Rapidly progressive pneumoconiosis with progressive massive fibrosis (complicated coal workers' pneumoconiosis) is being observed with increased frequency in United States coal miners, with histologic findings of silicosis and mixed-dust pneumoconiosis. There is increasing evidence of decline in lung function in individuals with pneumoconiosis. Multiple recent cohort studies suggest increased risk of lung cancer in coal miners. A detailed understanding of coal mining methods and processes allows clinicians to better evaluate and confirm chronic lung diseases caused by inhalational hazards in the mine atmosphere.

The Link between Reduced Inspiratory Capacity and Exercise Intolerance in Chronic Obstructive Pulmonary Disease.

Low inspiratory capacity (IC), chronic dyspnea, and reduced exercise capacity are inextricably linked and are independent predictors of increased mortality in chronic obstructive pulmonary disease. It is no surprise, therefore, that a major goal of management is to improve IC by reducing lung hyperinflation to improve respiratory symptoms and health-related quality of life. The negative effects of lung hyperinflation on respiratory muscle and cardiocirculatory function during exercise are now well established. Moreover, there is growing appreciation that a key mechanism of exertional dyspnea in chronic obstructive pulmonary disease is critical mechanical constraints on tidal volume expansion during exercise when resting IC is reduced. Further evidence for the importance of lung hyperinflation comes from multiple studies, which have reported the clinical benefits of therapeutic interventions that reduce lung hyperinflation and increase IC. A reduced IC in obstructive pulmonary disease is further eroded by exercise and contributes to ventilatory limitation and dyspnea. It is an important outcome for both clinical and research studies.

Inherited distal renal tubular acidosis (dRTA) is caused by impaired urinary acid excretion resulting in hyperchloremic metabolic acidosis. Although the glomerular filtration rate (GFR) is usually preserved, and hypertension and overt proteinuria are absent, it has to be considered that patients with dRTA also suffer from chronic kidney disease (CKD) with an increased risk for adverse pregnancy-related outcomes. Typical complications of dRTA include severe hypokalemia leading to cardiac arrhythmias and paralysis, nephrolithiasis and nephrocalcinosis. Several physiologic changes occur in normal pregnancy including alterations in acid-base and electrolyte homeostasis as well as in GFR. However, data on pregnancy in women with inherited dRTA are scarce. We report the course of pregnancy in three women with hereditary dRTA. Complications observed were severe metabolic acidosis, profound hypokalemia aggravated by hyperemesis gravidarum, recurrent urinary tract infection (UTI) and ureteric obstruction leading to renal failure. However, the outcome of all five pregnancies (1 pregnancy each for mothers n. 1 and 2; 3 pregnancies for mother n. 3) was excellent due to timely interventions. Our findings highlight the importance of close nephrologic monitoring of women with inherited dRTA during pregnancy. In addition to routine assessment of creatinine and proteinuria, caregivers should especially focus on acid-base status, plasma potassium and urinary tract infections. Patients should be screened for renal obstruction in the case of typical symptoms, UTI or renal failure. Furthermore, genetic identification of the underlying mutation may (a) support early nephrologic referral during pregnancy and a better management of the affected woman, and (b) help to avoid delayed diagnosis and reduce complications in affected newborns.

Background and study aims Complete stone removal from the main pancreatic duct might not be achieved in all patients with obstructive chronic calcific pancreatitis. We report our results for endoscopic dorsal pancreatic duct (DPD) bypass of obstructing stones in the ventral pancreatic duct (VPD). Patients and methods 16 patients with obstructive chronic calcific pancreatitis were treated with a DPD bypass. Clinical success was defined as significant pain relief and no hospital admissions for pain management during the ongoing treatment period. Results Among 16 patients meeting entry criteria, 10 (62.5%) had a history of unsuccessful endoscopic therapy, and 8 had failed extracorporeal shockwave lithotripsy (ESWL). Clinical success was achieved in 12 patients (75 %). Among these responders, 10 patients (83.3 %) had markedly improved or complete pain relief after the first stent placement, which persisted throughout the follow-up period; 11 patients (91.7 %) were able to discontinue their daily analgesics. Conclusions In selected patients with obstructive chronic calcific pancreatitis, the DPD bypass may be considered as a rescue endoscopic therapy, potentially obviating the need for surgery when standard endoscopic methods and ESWL fail.

Alpha-1 antitrypsin deficiency (AATD) predisposes to chronic obstructive pulmonary disease, but is underrecognized. Oxygenation and exercise desaturation in individuals with AATD-associated chronic obstructive pulmonary disease has been sparsely studied. The Long-term Oxygen Treatment Trial (LOTT) permits comparing these features of individuals with AATD with alpha-1 antitrypsin-replete (called "usual chronic obstructive pulmonary disease") LOTT participants. Compare demographic, clinical, baseline oxygenation, and exercise desaturation features in participating AATD subjects with those of other LOTT subjects. LOTT is a multicenter randomized controlled trial comparing use of supplemental oxygen versus not in subjects with chronic obstructive pulmonary disease and moderate hypoxemia (resting oxygen saturation as measured by pulse oximetry, 89-93%) or normal oxygen saturation at rest and significant exercise desaturation. Among the 597 LOTT participants with nonmissing alpha-1 antitrypsin levels, 11 (1.8%) had severe AATD and 44 (7.4%) had mild/moderate AATD. Comparison of the 11 severely AAT-deficient individuals with the 542 LOTT participants with usual chronic obstructive pulmonary disease showed that the AATD subjects were younger and despite less smoking, had lower FEV1/FVC (mean post-bronchodilator FEV1/FVC, 0.38 ± 0.06 vs. 0.46 ± 0.13; P = 0.002). Comparison with 27 age-, sex-, and FEV1-matched alpha-1 antitrypsin-normal LOTT participants showed no baseline difference in resting room air pulse oximetry saturation (AATD, 93.6% ± 2.3% vs. 92.7% ± 2.2%; P = 0.64). Exercise-related desaturation was more severe in the individuals with AATD based on desaturation to 88% or less sooner during a 6-minute-walk test, having a higher percentage of desaturation points (e.g., <90%) during exercise, and having a higher distance-saturation product (defined as the distance walked in 6 min multiplied by the nadir saturation achieved during the 6-minute-walk test). These data suggest that individuals with AATD experience more profound desaturation with exercise than age-, sex-, race-, and FEV1-matched control subjects with usual chronic obstructive pulmonary disease.

A new technique using cyanoacrylate glue is suggested for closing the transparenchymal tract following metallic endoprosthesis placement in a patient with malignant biliary obstruction complicated by ascites. With this technique, complications related to bile reflux through the transparenchymal tract would be avoided after transhepatic endoprosthesis placement in patients who have ascites. This technique would also be useful for avoiding bleeding following transhepatic portal venous puncture.

Urethral stent placement is an interventional treatment option to alleviate urethral outflow obstruction. It has been described utilizing fluoroscopy, but fluoroscopy is not as readily available in private practice as digital radiography. To describe the use of digital radiography for urethral stent placement in dogs with obstructive uropathy. Twenty-six client-owned dogs presented for dysuria associated with benign and malignant causes of obstructive uropathy that underwent urethral stent placement. Retrospective study. Causes of obstructive uropathy included transitional cell carcinoma, prostatic carcinoma, hemangiosarcoma, obstructive proliferative urethritis, compressive vaginal leiomyosarcoma, and detrusor-sphincter dyssynergia. Survival time range was 1-48 months (median, 5 months). All dogs were discharged from the hospital with urine outflow restored. Intraprocedural complications included guide wire penetration of the urethral wall in 1 dog and improper stent placement in a second dog. Both complications were successfully managed at the time of the procedure with no follow-up problems noted in either patient. Urethral stent placement can be successfully performed utilizing digital radiography. The complications experienced can be avoided by more cautious progression with each step through the procedure and serial radiography. The application of digital radiography may allow treatment of urethral obstruction to become more readily available. Copyright © 2017 The Authors.

A brief review of chronic obstructive pulmonary disease.

PubMed

Hogg, James C

2012-01-01

A recent study, based on a combination of multidetector computed tomography scanning of an intact specimen with microcomputed tomography and histological analysis of lung tissue samples, reported that the number of terminal bronchioles were reduced from approximately 44,500/lung pair in control (donor) lungs to approximately 4800/lung pair in lungs donated by individuals with very severe (Global initiative for chronic Obstructive Lung Disease stage 4) chronic obstructive pulmonary disease (COPD) treated by lung transplantation. The present short review discusses the hypothesis that a rapid rate of terminal bronchiolar destruction causes the rapid decline in lung function leading to advanced COPD. With respect to why the terminal bronchioles are targeted for destruction, the postulated mechanisms of this destruction and the possibility that new treatments are able to either prevent or reverse the underlying cause of airway obstruction in COPD are addressed.

To evaluate the effectiveness of a 6-month, partnership-based self-management programme for patients with mild and moderate chronic obstructive pulmonary disease. Self-management is a widely valued concept used to address contemporary issues of chronic health problems. Findings of self-management programmes for people with chronic obstructive pulmonary disease are inconclusive. Pragmatic randomized control trial. Patients, 45-65 years old, with mild and moderate chronic obstructive pulmonary disease were invited with a family member. Experimental group (n = 48) participated in a 6-month, partnership-based self-management programme consisting of: (a) three to four conversations between nurse and patient-family member; (b) 6 months of smoking cessation; and (c) interdisciplinary team-patient-family member group meeting. Control group (n = 52) received usual care. Data were collected at months zero, six and 12. The trial lasted from June 2009-March 2013. Patients with mild and moderate chronic obstructive pulmonary disease who participated in the partnership-based self-management programme perceived less intrusiveness of the disease and its treatment than patients in the control group. Patients in the experimental group did not have better health-related quality of life, less anxiety or depression, increased physical activity, fewer exacerbations or better smoking status than patients in the control group. Patients in both groups found participation in the research useful and important. The partnership-based self-management programme had benefits concerning perception of the intrusiveness of chronic obstructive pulmonary disease and its treatment on lifestyles, activities and interests for young patients with the disease in its early stages. High satisfaction in control group, low family attendance and the relatively short treatment period may explain the less than expected benefits of the programme. © 2015 John Wiley & Sons Ltd.

Pronation might favorably affect respiratory system (rs) mechanics and function in volume-controlled, mode-ventilated chronic obstructive pulmonary disease (COPD) patients. We studied 10 COPD patients, initially positioned supine (baseline supine [supine(BAS)]) and then randomly and consecutively changed to protocol supine (supine(PROT)), semirecumbent, and prone positions. Rs mechanics and inspiratory work (W(I)) were assessed at baseline (0.6 L) (all postures) and sigh (1.2 L) (supine(BAS) excluded) tidal volume (V(T)) with rapid airway occlusion during constant-flow inflation. Hemodynamics and gas exchange were assessed in all postures. There were no complications. Prone positioning resulted in (a) increased dynamic-static chest wall (cw) elastance (at both V(Ts)) and improved oxygenation versus supine(BAS), supine(PROT), and semirecumbent, (b) decreased additional lung (L) resistance-elastance versus supine(PROT) and semirecumbent at sigh V(T), (c) decreased L-static elastance (at both V(Ts)) and improved CO(2) elimination versus supine(BAS) and supine(PROT), and (d) improved oxygenation versus all other postures. Semirecumbent positioning increased mainly additional cw-resistance versus supine(BAS) and supine(PROT) at baseline. V(T) W(I)-sub-component changes were consistent with changes in rs, cw, and L mechanical properties. Total rs-W(I) and hemodynamics were unaffected by posture change. After pronation, five patients were repositioned supine (supine(POSTPRO)). In supine(POSTPRO), static rs-L elastance were lower, and oxygenation was still improved versus supine(BAS). Pronation of mechanically ventilated COPD patients exhibits applicability and effectiveness and improves oxygenation and sigh-L mechanics versus semirecumbent ("gold standard") positioning. By assessing respiratory mechanics, inspiratory work, hemodynamics, and gas exchange, we showed that prone positioning of mechanically ventilated chronic obstructed pulmonary disease patients improves oxygenation and lung mechanics during sigh versus semirecumbent positioning. Furthermore, certain pronation-related benefits versus preprone-supine positioning (reduced lung elastance and improved oxygenation) are maintained in the postprone supine position.

Introduction The prescription of physical activity for hospitalized patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) can be complicated by the presence of comorbidities. The current research aimed to synthesize the relevant literature on the benefits of exercise for people with multimorbidities who experience an AECOPD, and ask: What are the parameters and outcomes of exercise in AECOPD and in conditions that are common comorbidities as reported by systematic reviews (SRs)? Methods An SR was performed using the Cochrane Collaboration protocol. Nine electronic databases were searched up to July 2011. Articles were included if they (1) described participants with AECOPD, chronic obstructive pulmonary disease (COPD), or one of eleven common comorbidities, (2) were an SR, (3) examined aerobic training (AT), resistance training (RT), balance training (BT), or a combination thereof, (4) included at least one outcome of fitness, and (5) compared exercise training versus control/sham. Results This synthesis examined 58 SRs of exercise training in people with AECOPD, COPD, or eleven chronic conditions commonly associated with COPD. Meta-analyses of endurance (aerobic or exercise capacity, 6-minute walk distance – 6MWD) were shown to significantly improve in most conditions (except osteoarthritis, osteoporosis, and depression), whereas strength was shown to improve in five of the 13 conditions searched: COPD, older adults, heart failure, ischemic heart disease, and diabetes. Several studies of different conditions also reported improvements in quality of life, function, and control or prevention outcomes. Meta-analyses also demonstrate that exercise training decreases the risk of mortality in older adults, and those with COPD or ischemic heart disease. The most common types of training were AT and RT. BT and functional training were commonly applied in older adults. The quality of the SRs for most conditions was moderate to excellent (>65%) as evaluated by AMSTAR scores. Conclusion In summary, this synthesis showed evidence of significant benefits from exercise training in AECOPD, COPD, and conditions that are common comorbidities. A broader approach to exercise and activity prescription in pulmonary rehabilitation may induce therapeutic benefits to ameliorate clinical sequelae associated with AECOPD and comorbidities such as the inclusion of BT and functional training.

Opioids are frequently used in chronic pain management but are associated with significant morbidity and mortality in some patient populations. An important avenue for identifying complications-including serious or rare complications-is the study of closed malpractice claims. The present study is intended to complement the existing closed claims literature by drawing on claims from a more recent timeframe through a partnership with a large malpractice carrier, the Controlled Risk Insurance Company (CRICO). The goal of this study was to identify patient medical comorbidities and aberrant drug behaviors, as well as prescriber practices associated with patient injury and malpractice claims. Another objective was to identify claims most likely to result in payments and use this information to propose a strategy for reducing medicolegal risk. The CRICO Strategies Comparative Benchmarking System is a database of claims drawing from >350,000 malpractice claims from Harvard-affiliated institutions and >400 other academic and community institutions across the United States. This database was queried for closed claims from January 1, 2009, to December 31, 2013, and identified 37 cases concerning noninterventional, outpatient chronic pain management. Each file consisted of a narrative summary, including expert witness testimony, as well as coded fields for patient demographics, medical comorbidities, the alleged damaging event, the alleged injurious outcome, the total financial amount incurred, and more. We performed an analysis using these claim files. The mean patient age was 43.5 years, with men representing 59.5% of cases. Payments were made in 27% of cases, with a median payment of $72,500 and a range of $7500-$687,500. The majority of cases related to degenerative joint disease of the spine and failed back surgery syndrome; no patients in this series received treatment of malignant pain. Approximately half (49%) of cases involved a patient death. The use of long-acting opioids and medical conditions affecting the cardiac and pulmonary systems were more closely associated with death than with other outcomes. The nonpain medical conditions present in this analysis included obesity, obstructive sleep apnea, chronic obstructive pulmonary disease, hypertension, and coronary artery disease. Other claims ranged from alleged addiction to opioids from improper prescribing to alleged abandonment with withdrawal of care. The CRICO analysis suggested that patient behavior contributed to over half of these claims, whereas deficits in clinical judgment contributed to approximately 40% of the claims filed. Claims related to outpatient medication management in pain medicine are multifactorial, stemming from deficits in clinical judgment by physicians, noncooperation in care by patients, and poor clinical documentation. Minimization of both legal risk and patient harm can be achieved by carefully selecting patients for chronic opioid therapy and documenting compliance and improvement with the treatment plan. Medical comorbidities such as obstructive sleep apnea and the use of long-acting opioids may be particularly dangerous. Continuing physician education on the safest and most effective approaches to manage these medications in everyday practice will lead to both improved legal security and patient safety.

Chronic obstructive pulmonary disease (COPD) is frequently associated with comorbidities occurring either independently or as consequences of COPD. Areas covered: This review examines the interactions between the pathophysiology of COPD and the most frequent comorbidities, and highlights the need for multidimensional clinical strategies to manage COPD patients with comorbidities. Expert commentary: Most COPD patients need to be approached in a complex and multifactorial scenario. The diagnosis of COPD is necessarily based on the presence of chronic respiratory symptoms and poorly reversible airflow obstruction, but exacerbations and comorbidities need to be considered in the evaluation of disease severity and prognosis in individual patients. More importantly, defining the precise relationship between COPD and comorbidities for each patient is the basis for a correct therapeutic approach.

It was aimed to concern about the satisfaction and procedural complications of patients during the thoracoscopy exist of hands-on training in this present study. The patients with non-small-cell carcinoma underwent video-assisted thoracoscopic surgery (VATS) lobectomy during hands-on training courses at thoracoscopic center in our hospital and collected from January 2009 and December 2014. The rates of satisfaction and complications of patients were compared from hands-on training group and control group. Potential risk factors associated with post-VATS complications of patients and thoracoscopist-related variables were analyzed. There were 54 patients join in six meetings with hands-on thoracoscopy training in our center. There was no significant difference between patients for hands-on training group (n = 54) and control group (n = 54), including sex, age, BMI, smoking, PpoFEV1 and comorbidities. The satisfaction rate and the incidence of complication were similar between the two groups. Univariate analyses showed that elder age, heart disease, chronic obstructive pulmonary disease, long operative time, and first-time mentorship were significantly associated with post-VATS complications of patients in hands-on training group. We should pay more attention to the characteristics of patent and the experience of mentor before VATS hands-on training courses.

Elephantiasis nostras verrucosa is a rare cutaneous complication of chronic lymphatic obstruction. It is most commonly caused by bacterial infection, trauma, neoplasia, obesity, and venous stasis. In this report, we describe a case of elephantiasis nostras verrucosa involving the scrotum and perineal area in a 32-year-old. The lesions were excised, and full-thickness skin grafting of the penis, scrotum, and perineal skin was performed. This case demonstrates the efficacy of excision with full-thickness skin grafting of the penis, scrotum, and perineal area in a patient with elephantiasis nostras verrucosa confined to the scrotum and perineal region.

We present a previously undocumented complication of dystrophic calcification of the prostate after cryotherapy. An 87-year-old male presented with recurrent lower urinary tract infections and was found to have an obstructing large calcified mass in the right lobe of the prostate. Subsequently, he underwent transurethral resection of the prostate (TURP) and bladder neck with laser lithotripsy to remove the calculus. We propose that chronic inflammation and necrosis of the prostate from cryotherapy resulted in dystrophic calcification of the prostate. As the use of cryotherapy for the treatment of localized prostate cancer continues to increase, it is important that clinicians be aware of this scenario and the technical challenges it poses.

The development of atherosclerosis is a multi-step process, at least in part controlled by the vascular endothelium function. Observations in humans and experimental models of atherosclerosis have identified monocyte recruitment as an early event in atherogenesis. Chronic inflammation is associated with ageing and its related diseases (e.g., atherosclerosis and chronic obstructive pulmonary disease). Recently it has been discovered that Sirtuins (NAD+-dependent deacetylases) represent a pivotal regulator of longevity and health. They appear to have a prominent role in vascular biology and regulate aspects of age-dependent atherosclerosis. Many studies demonstrate that SIRT1 exhibits anti-inflammatory properties in vitro (e.g., fatty acid-induced inflammation), in vivo (e.g., atherosclerosis, sustainment of normal immune function in knock-out mice) and in clinical studies (e.g., patients with chronic obstructive pulmonary disease). Because of a significant reduction of SIRT1 in rodent lungs exposed to cigarette smoke and in lungs of patients with chronic obstructive pulmonary disease (COPD), activation of SIRT1 may be a potential target for chronic obstructive pulmonary disease therapy. We review the inflammatory mechanisms involved in COPD-CVD coexistence and the potential role of SIRT1 in the regulation of these systems. PMID:23774840

Physical inactivity and obesity: relation to asthma and chronic obstructive pulmonary disease?

PubMed

ten Hacken, Nick H T

2009-12-01

Physical inactivity and obesity are modifiable risk factors for many chronic diseases, including cardiovascular disease, diabetes mellitus, osteoporosis, osteoarthritis, and depression. Both physical inactivity and obesity are associated with low-grade systemic inflammation that may contribute to the inflammatory processes present in many chronic diseases. In asthma, almost no studies are available in which physical inactivity has been studied using performance-based instruments. In contrast, the association between obesity and a higher prevalence of asthma has often been suggested in a large number of studies. In chronic obstructive pulmonary disease (COPD) physical inactivity has been demonstrated in a few studies that used performance-based instruments; this was associated with the higher COPD Global Initiative on Obstructive Lung Disease (GOLD) stages and a higher degree of systemic inflammation, independent of body mass index. In contrast to physical inactivity, obesity in COPD is associated with the lower GOLD stages. Additionally, obesity is associated with the chronic obstructive phenotype and features of the metabolic syndrome. To elucidate the independent relation of physical inactivity and obesity with systemic inflammation, performance-based studies of physical inactivity in asthma and COPD are highly needed.

[Surgical treatment of chronic pancreatitis, 2010].

Chronic pancreatitis (CP) is a benign inflammatory process, which can cause enlargement of the pancreatic head accompanied by severe pain and weight loss, and often leads to a significant reduction in quality of life (QoL). Basically, the disease is characterised by pain and functional disorders which are initially treated with conservative therapy, but in case of complications (uncontrollable pain or obstruction) surgical treatment is required. This article reviews the relevant literature of CP treatment, in particular randomized controlled trials and meta-analyses were involved with a comparison of different surgical treatment options for the management of CP complications. Recent studies have demonstrated that surgical procedures are superior to endoscopic therapy as regards long-term results of QoL and pain control. There was no significant difference found in postoperative pain relief and overall mortality when duodenum-preserving pancreatic head resection (DPPHR) of Beger and its modification (duodenum and organ-preserving pancreatic head resection [DOPPHR]) were compared with pancreatoduodenectomy (PD), but hospital stay, weight gain, exocrine and endocrine insufficiency, and QoL were significantly better in the DPPHR and DOPPHR groups. DPPHR and PD seem to be equally effective in terms of postoperative pain relief and overall mortality. However, recent data suggest that DOPPHR is superior in the treatment of CP with regard to several peri- and postoperative outcome parameters and QoL. Therefore, this should be the preferable treatment option for CP complications.

Pre-operative optimisation of lung function

PubMed Central

Azhar, Naheed

2015-01-01

The anaesthetic management of patients with pre-existing pulmonary disease is a challenging task. It is associated with increased morbidity in the form of post-operative pulmonary complications. Pre-operative optimisation of lung function helps in reducing these complications. Patients are advised to stop smoking for a period of 4–6 weeks. This reduces airway reactivity, improves mucociliary function and decreases carboxy-haemoglobin. The widely used incentive spirometry may be useful only when combined with other respiratory muscle exercises. Volume-based inspiratory devices have the best results. Pharmacotherapy of asthma and chronic obstructive pulmonary disease must be optimised before considering the patient for elective surgery. Beta 2 agonists, inhaled corticosteroids and systemic corticosteroids, are the main drugs used for this and several drugs play an adjunctive role in medical therapy. A graded approach has been suggested to manage these patients for elective surgery with an aim to achieve optimal pulmonary function. PMID:26556913

Retroperitoneal fibrosis.

2014-10-01

Retroperitoneal fibrosis (RPF) is a rare disease that is marked by systemic inflammation and the development of a periaortic fibroinflammatory mass. The fibroinflammatory infiltration can encase the abdominal aorta, ureters, and other abdominal organs. The clinical presentation often includes constitutional symptoms, abdominal pain, and signs of renal insufficiency or renal failure related to ureteral obstruction. Less frequently, RPF may present with vascular complications, such as venous thrombosis or claudication. The idiopathic form of RPF is most common but secondary forms have been described and are associated with malignancy and a variety of different medications. The pathophysiology is uncertain, but RPF has been linked with periaortitis and IgG4-related disease. Treatment centers on the relief of symptoms and complications associated with mass effects. Corticosteroids and other immunosuppressant therapies can improve constitutional symptoms, reduce infiltrate mass, and achieve disease remission, but a chronic relapsing course is not uncommon. © The Author(s) 2014.

Pulmonary complications of endocrine and metabolic disorders.

There are many important respiratory manifestations of endocrine and metabolic diseases in children. Acute and chronic pulmonary infections are the most common respiratory abnormalities in patients with diabetes mellitus, although cardiogenic and non-cardiogenic pulmonary oedema are also possible. Pseudohypoaldosteronism type 1 may be indistinguishable from cystic fibrosis (CF) unless serum aldosterone, plasma renin activity, and urinary electrolytes are measured and mutation analysis rules out CF. Hypo- and hyperthyroidism may alter lung function and affect the central respiratory drive. The thyroid hormone plays an essential role in lung development, surfactant synthesis, and lung defence. Complications of hypoparathyroidism are largely due to hypocalcaemia. Laryngospasm can lead to stridor and airway obstruction. Ovarian tumours, benign or malignant, may present with unilateral or bilateral pleural effusions. Metabolic storage disorders, primarily as a consequence of lysosomal dysfunction from enzymatic deficiencies, constitute a diverse group of rare conditions that can have profound effects on the respiratory system.

Pneumothorax as a complication of lung volume recruitment.

PubMed

Westermann, Erik J A; Jans, Maurice; Gaytant, Michael A; Bach, John R; Kampelmacher, Mike J

2013-01-01

Lung volume recruitment involves deep inflation techniques to achieve maximum insufflation capacity in patients with respiratory muscle weakness, in order to increase peak cough flow, thus helping to maintain airway patency and improve ventilation. One of these techniques is air stacking, in which a manual resuscitator is used in order to inflate the lungs. Although intrathoracic pressures can rise considerably, there have been no reports of respiratory complications due to air stacking. However, reaching maximum insufflation capacity is not recommended in patients with known structural abnormalities of the lungs or chronic obstructive airway disease. We report the case of a 72-year-old woman who had poliomyelitis as a child, developed torsion scoliosis and post-polio syndrome, and had periodic but infrequent asthma attacks. After performing air stacking for 3 years, the patient suddenly developed a pneumothorax, indicating that this technique should be used with caution or not at all in patients with a known pulmonary pathology.

Patients with chronic obstructive pulmonary disease of moderate severity were investigated for two months for assessment of fenspiride activity. Examination of the patients (age 42.6 +/- 5.3) took place before and after fenspiride therapy. In comparison to the control group, fenspiride patients showed improvement of external respiration function: FEV 1, FVC, FEF 50-75, PEF increased. Dienic conjugates, malonic dialdehyde levels decreased, alpha-tocopherol in platelet membranes rose, functional activity of platelets fell. Side effects were rare and not serious. It is concluded that fenspiride has an antiinflammatory effect, reduces bronchoconstriction and depresses platelet aggregation, is well tolerated. Fenspiride is an effective drug for the treatment of moderate chronic obstructive bronchitis.

To determine the incidence of urological complications of renal transplantation at one institution, and relate this to donor and recipient factors. A consecutive series of 1535 renal transplants were audited, and a database of donor and recipient characteristics created for risk-factor analysis. An unstented Leadbetter-Politano anastomosis was the preferred method of ureteric reimplantation. There were 45 urinary leaks, 54 primary ureteric obstructions, nine cases of ureteric calculi, three bladder stones and 19 cases of bladder outlet obstruction at some time after transplantation. The overall incidence of urological complications was 9.2%, with that for urinary leak or primary ureteric obstruction being 6.5%. One graft was lost because of complications, and there were three deaths associated directly or indirectly with urological complications. There was no association with recipient age, cadaveric vs living-donor transplants, or cold ischaemic times before organ reimplantation, although the donor age was slightly higher in cases of urinary leak. There was no association with kidneys imported via the UK national organ-sharing scheme vs the use of local kidneys. The management of these complications is discussed. The incidence of urological complications in this series has remained essentially unchanged for 20 years. The causes of these complications and techniques for their prevention are discussed.

Infectious mononucleosis (IM) is a disease traditionally defined by a triad of clinical, laboratory, and serologic factors. It is typically a benign, self-limited disease of children and young adults. Upper airway obstruction is a rare but potentially fatal complication of IM resulting from massive tonsillar enlargement, pharyngeal edema, or both. We report a case of sudden death due to airway obstruction in IM.

2016-01-01

HIV infection has shifted from what was once a disease directly impacting short-term mortality to what is now a chronic illness controllable in the era of effective combination antiretroviral therapy (ART). In this setting, life expectancy for HIV-infected individual is nearly comparable to that of individuals without HIV. Subsequent to this increase in life expectancy, there has been recognition of increased multimorbidity among HIV-infected persons, with prevalence of comorbid chronic illnesses now approaching 65%. Obstructive lung diseases, including chronic obstructive pulmonary disease (COPD) and asthma, are prevalent conditions associated with substantial morbidity and mortality in the United States. There is overlap in risk factors for HIV acquisition and chronic lung diseases, including lower socioeconomic status and the use of tobacco and illicit drugs. Objectives of this review are to (1) summarize the current state of knowledge regarding COPD and asthma among HIV-infected persons, (2) highlight implications for clinicians caring for patients with these combined comorbidities, and (3) identify key research initiatives to reduce the burden of obstructive lung diseases among HIV-infected persons.

Courvoisier's gallbladder: law or sign?

PubMed

Fitzgerald, J Edward F; White, Matthew J; Lobo, Dileep N

2009-04-01

Variously described as Courvoisier's law, sign, or even gallbladder, this eponymous "law" has been taught to medical students since the publication of Courvoisier's treatise in 1890. We reviewed Courvoisier's original "law," the modern misconceptions surrounding it, and the contemporary evidence supporting and explaining his observations. Courvoisier never stated a "law" in the context of a jaundiced patient with a palpable gallbladder. He described 187 cases of common bile duct obstruction, observing that gallbladder dilatation seldom occurred with stone obstruction of the bile duct. The classic explanation for Courvoisier's finding is based on the underlying pathologic process. With the presence of gallstones come repeated episodes of infection and subsequent fibrosis of the gallbladder. In the event that a gallstone causes the obstruction, the gallbladder is shrunken owing to fibrosis and is unlikely to be distensible and, hence, palpable. With other causes of obstruction, the gallbladder distends as a result of the back-pressure from obstructed bile flow. However, recent experiments show that gallbladders are equally distensible in vitro, irrespective of the pathology, suggesting that chronicity of the obstruction is the key. Chronically elevated intraductal pressures are more likely to develop with malignant obstruction owing to the progressive nature of the disease. Gallstones cause obstruction in an intermittent fashion, which is generally not consistent enough to produce such a chronic rise in pressure. We hope that reminding clinicians of Courvoisier's actual observations will reestablish the usefulness of this clinical sign in the way he intended.

BACKGROUND: There are significant variations in how therapeutic bronchoscopy for malignant airway obstruction is performed. Relatively few studies have compared how these approaches affect the incidence of complications. METHODS: We used the American College of Chest Physicians (CHEST) Quality Improvement Registry, Evaluation, and Education (AQuIRE) program registry to conduct a multicenter study of patients undergoing therapeutic bronchoscopy for malignant central airway obstruction. The primary outcome was the incidence of complications. Secondary outcomes were incidence of bleeding, hypoxemia, respiratory failure, adverse events, escalation in level of care, and 30-day mortality. RESULTS: Fifteen centers performed 1,115 procedures on 947 patients. There were significant differences among centers in the type of anesthesia (moderate vs deep or general anesthesia, P < .001), use of rigid bronchoscopy (P < .001), type of ventilation (jet vs volume cycled, P < .001), and frequency of stent use (P < .001). The overall complication rate was 3.9%, but significant variation was found among centers (range, 0.9%-11.7%; P = .002). Risk factors for complications were urgent and emergent procedures, American Society of Anesthesiologists (ASA) score > 3, redo therapeutic bronchoscopy, and moderate sedation. The 30-day mortality was 14.8%; mortality varied among centers (range, 7.7%-20.2%, P = .02). Risk factors for 30-day mortality included Zubrod score > 1, ASA score > 3, intrinsic or mixed obstruction, and stent placement. CONCLUSIONS: Use of moderate sedation and stents varies significantly among centers. These factors are associated with increased complications and 30-day mortality, respectively. PMID:25741903

Background Severe α1‐antitrypsin (AAT) deficiency is an autosomal recessive genetic condition associated with an increased but variable risk for chronic obstructive pulmonary disease (COPD). A study was undertaken to assess the impact of chronic bronchitis, pneumonia, asthma and sex on the development of COPD in individuals with severe AAT deficiency. Methods The AAT Genetic Modifier Study is a multicentre family‐based cohort study designed to study the genetic and epidemiological determinants of COPD in AAT deficiency. 378 individuals (age range 33–80 years), confirmed to be homozygous for the SERPINA1 Z mutation, were included in the analyses. The primary outcomes of interest were a quantitative outcome, forced expiratory volume in 1 s (FEV1) percentage predicted, and a qualitative outcome, severe airflow obstruction (FEV1 <50% predicted). Results In multivariate analysis of the overall cohort, cigarette smoking, sex, asthma, chronic bronchitis and pneumonia were risk factors for reduced FEV1 percentage predicted and severe airflow obstruction (p<0.01). Index cases had lower FEV1 values, higher smoking histories and more reports of adult asthma, pneumonia and asthma before age 16 than non‐index cases (p<0.01). Men had lower pre‐ and post‐bronchodilator FEV1 percentage predicted than women (p<0.0001); the lowest FEV1 values were observed in men reporting a history of childhood asthma (26.9%). This trend for more severe obstruction in men remained when index and non‐index groups were examined separately, with men representing the majority of non‐index individuals with airflow obstruction (71%). Chronic bronchitis (OR 3.8, CI 1.8 to 12.0) and a physician's report of asthma (OR 4.2, CI 1.4 to 13.1) were predictors of severe airflow obstruction in multivariate analysis of non‐index men but not women. Conclusion In individuals with severe AAT deficiency, sex, asthma, chronic bronchitis and pneumonia are risk factors for severe COPD, in addition to cigarette smoking. These results suggest that, in subjects severely deficient in AAT, men, individuals with symptoms of chronic bronchitis and/or a past diagnosis of asthma or pneumonia may benefit from closer monitoring and potentially earlier treatment.

Peak flow meter with questionnaire and mini-spirometer are considered as alternative tools to spirometry for screening of asthma and chronic obstructive pulmonary disease. However, the accuracy of these tools together, in clinical settings for disease diagnosis, has not been studied. Two hundred consecutive patients with respiratory complaints answered a short symptom questionnaire and performed peak expiratory flow measurements, standard spirometry with Koko spirometer and mini-spirometry (COPD-6). Spirometry was repeated after bronchodilation. Physician made a final diagnosis of asthma, chronic obstructive pulmonary disease and others. One eighty nine patients (78 females) with age 51 ± 17 years with asthma (115), chronic obstructive pulmonary disease (33) and others (41) completed the study. "Breathlessness > 6months" and "cough > 6months" were important symptoms to detect obstructive airways disease. "Asymptomatic period > 2 weeks" had the best sensitivity (Sn) and specificity (Sp) to differentiate asthma and chronic obstructive pulmonary disease. A peak expiratory flow of < 80% predicted was the best cut-off to detect airflow limitation (Sn 90%, Sp 50%). Respiratory symptoms with PEF < 80% predicted, had Sn 84 and Sp 93% to detect OAD. COPD-6 device under-estimated FEV 1 by 13 mL (95% CI: -212, 185). At a cut-off of 0.75, the FEV 1 /FEV 6 had the best accuracy (Sn 80%, Sp 86%) to detect airflow limitation. Peak flow meter with few symptom questions can be effectively used in clinical practice for objective detection of asthma and chronic obstructive pulmonary disease, in the absence of good quality spirometry. Mini-spirometers are useful in detection of obstructive airways diseases but FEV 1 measured is inaccurate. DIFFERENTIATING CONDITIONS IN POORLY-EQUIPPED SETTINGS: A simple questionnaire and peak flow meter measurements can help doctors differentiate between asthma and chronic lung disease. In clinical settings where access to specialist equipment and knowledge is limited, it can be challenging for doctors to tell the difference between asthma and chronic obstructive pulmonary disease (COPD). To determine a viable alternative method for differentiating between these diseases, Rahul Kodgule and colleagues at the Chest Research Foundation in Pune, India, trialed a simplified version of two existing symptom questionnaires, combined with peak flow meter measurements. They assessed 189 patients using this method, and found it aided diagnosis with high sensitivity and specificity. Breathlessness, cough and wheeze were the minimal symptoms required for COPD diagnosis, while the length of asymptomatic periods was most helpful in distinguishing asthma from COPD.

Background: We sought to develop and externally validate a nomogram and web-based calculator to individually predict the development of serious complications in seemingly stable adult patients with solid tumours and episodes of febrile neutropenia (FN). Patients and methods: The data from the FINITE study (n=1133) and University of Salamanca Hospital (USH) FN registry (n=296) were used to develop and validate this tool. The main eligibility criterion was the presence of apparent clinical stability, defined as events without acute organ dysfunction, abnormal vital signs, or major infections. Discriminatory ability was measured as the concordance index and stratification into risk groups. Results: The rate of infection-related complications in the FINITE and USH series was 13.4% and 18.6%, respectively. The nomogram used the following covariates: Eastern Cooperative Group (ECOG) Performance Status ⩾2, chronic obstructive pulmonary disease, chronic cardiovascular disease, mucositis of grade ⩾2 (National Cancer Institute Common Toxicity Criteria), monocytes <200/mm3, and stress-induced hyperglycaemia. The nomogram predictions appeared to be well calibrated in both data sets (Hosmer–Lemeshow test, P>0.1). The concordance index was 0.855 and 0.831 in each series. Risk group stratification revealed a significant distinction in the proportion of complications. With a ⩾116-point cutoff, the nomogram yielded the following prognostic indices in the USH registry validation series: 66% sensitivity, 83% specificity, 3.88 positive likelihood ratio, 48% positive predictive value, and 91% negative predictive value. Conclusions: We have developed and externally validated a nomogram and web calculator to predict serious complications that can potentially impact decision-making in patients with seemingly stable FN.

To explore the classification, choice of surgical procedures and the clinical outcome of surgical management for chronic pancreatitis. 54 patients with chronic pancreatitis undergoing operation in our hospital from 1983 to 2004 were analyzed retrospectively, who were divided into chronic calcifying pancreatitis and chronic obstructive pancreatitis according to the clinical manifestations. There were 41 men (76%) and 13 women (24%) with a mean age of 54 years. The cause of chronic pancreatitis was alcohol related in 25 cases (46%), cholelithiasis in 21 (39%), and previous episodes of acute pancreatitis in 18 (33%). Clinical manifestations included abdominal pain in 38 cases (70%), obstructive jaundice in 27 cases (50%). There existed a significant difference in some clinical materials between the two groups of chronic calcifying pancreatitis and chronic obstructive pancreatitis, which might mean the different pathologic basis in the two kinds of chronic pancreatitis. A total of 34 patients underwent nine different operations without perioperative deaths. Both the Puestow procedure and the pancreatoduodenectomy was safe and achieved pain relief in a large percentage of patients, which could also improve the exocrine function whereas the endocrine function remained unchanged. Addition of biliary bypass to the Puestow procedure was suitable for the patients with stenosis of common bile duct. Jaundice was the main manifestation in the patients with the inflammatory mass in the head of the pancreas and Whipple's procedure or other resectional procedures should be performed for them. Only drainage of bile duct had a better outcome for the relief of jaundice, but its effect to pancreas need to be further evaluated. The clinicopathologic characteristics of obstructive chronic pancreatitis was more variable and the surgical management should be also different for individuals.

Physical exercise training is an evidence-based treatment in chronic obstructive pulmonary disease, and patients' peak work rate is associated with reduced chronic obstructive pulmonary disease mortality. We assessed whether supplemental oxygen during exercise training in nonhypoxemic patients with chronic obstructive pulmonary disease might lead to superior training outcomes, including improved peak work rate. This was a randomized, double-blind, controlled, crossover trial. Twenty-nine patients with chronic obstructive pulmonary disease (aged 63.5 ± 5.9 years; forced expiratory volume in 1 second percent predicted, 46.4 ± 8.6) completed 2 consecutive 6-week periods of endurance and strength training with progressive intensity, which was performed 3 times per week with supplemental oxygen or compressed medical air (flow via nasal cannula: 10 L/min). Each session of electrocardiography-controlled interval cycling lasted 31 minutes and consisted of a warm-up, 7 cycles of 1-minute intervals at 70% to 80% of peak work rate alternating with 2 minutes of active recovery, and final cooldown. Thereafter, patients completed 8 strength-training exercises of 1 set each with 8 to 15 repetitions to failure. Change in peak work rate was the primary study end point. The increase in peak work rate was more than twice as high when patients exercised with supplemental oxygen compared with medical air (0.16 ± 0.02 W/kg vs 0.07 ± 0.02 W/kg; P < .001), which was consistent with all other secondary study end points related to exercise capacity. The impact of oxygen on peak work rate was 39.1% of the overall training effect, whereas it had no influence on strength gain (P > .1 for all exercises). We report that supplemental oxygen in nonhypoxemic chronic obstructive pulmonary disease doubled the effect of endurance training but had no effect on strength gain. Copyright © 2016 Elsevier Inc.

To examine the experiences with palliative care in people with chronic obstructive pulmonary disease among professional caregivers in a Danish home care setting. Many patients with advanced chronic obstructive pulmonary disease depend on professional caregivers in the primary sector to provide assistance and care. However, chronic obstructive pulmonary disease patients receive no or only very little palliative care compared to patients with cancer although they may have many burdensome symptoms. Qualitative explorative study. In 2013-2014, ten professional caregivers from three districts in a Danish municipality were followed during home visits to patients with chronic obstructive pulmonary disease and individual interviews about palliative care were subsequently conducted. In 2014, 66 professional caregivers, representing eleven home care districts, participated in ten group discussions about palliative care needs in this group of patients. Data were analysed using qualitative descriptive analysis. The study revealed a nonawareness of palliative care for patients with chronic obstructive pulmonary disease among the professional caregivers who expressed vague understanding of palliative care and lack of knowledge about the disease. Organisational barriers, such as lack of time and continuity in patient care, lack of opportunity to discuss palliative care and lack of peer learning were experienced as challenging in the provision of palliative care. Nonawareness and organisational barriers led to difficulties in identifying palliative care needs and reluctance to initiate conversations about palliative care. The findings indicate a need for education, training and reflection among professional caregivers in home care. Also, organisational changes may be needed to reduce the barriers to palliative care. The findings uncovered barriers to palliative care that must be addressed. Targeted educational programmes and organisational changes may increase the ability to identify palliative care needs and initiate and evaluate palliative interventions. © 2017 John Wiley & Sons Ltd.

The aim of the study was to describe and compare nutritional status and social and medical characteristics among older patients with chronic obstructive pulmonary disease admitted to an acute care hospital ward for respiratory medicine. Chronic obstructive pulmonary disease is a condition associated with risk of developing malnutrition. A body mass index <20 is predictive of hospitalisation for acute exacerbations of chronic obstructive pulmonary disease. Knowledge about patient characteristics is crucial for the identification of malnourished patients and the development of nursing care for these patients. Quantitative descriptive study. Thirty-three hospitalised women and 17 men with a mean age of 75.7 years (SD 6.9) were consecutively included. A very severe case of chronic obstructive pulmonary disease was indicated in 28 out of 39 patients who underwent a lung function test. Data were collected with measurement of nutritional status using Mini Nutritional Assessment, anthropometry and lung function. Nearly half of the patients (48%) were identified as malnourished, an equal part as at risk for malnutrition and two patients as well nourished. The mean Mini Nutritional Assessment score of 17.2 (SD 3.99) for all patients was near the Mini Nutritional Assessment cut-off score (i.e. 17) for malnutrition. Patients identified as malnourished had a mean body mass index of 18.9 and those at risk for malnutrition had a mean of 23.4. It was more common for those identified as malnourished to live singly, to not live in own property and to be dependent on daily community service. Seven patients identified as malnourished died during the data collection period. This study provides important knowledge about further risks of impaired nutritional status among older patients with chronic obstructive pulmonary disease. This knowledge can provide registered nurses with the necessary knowledge to make them aware of certain patients needing particular kinds of attention.

Background Silent/asymptomatic peripheral artery disease may occur in patients with chronic obstructive pulmonary disease, but it is poorly investigated. The primary aim of this study was to evaluate in chronic obstructive pulmonary disease patients the impact of asymptomatic/silent peripheral artery disease on maximal exercise capacity; the secondary aim was to search for predictors of peripheral artery disease. Methods We prospectively enrolled chronic obstructive pulmonary disease outpatients. Data on anthropometric characteristics, lung function, cardiopulmonary exercise test and ankle-brachial index were recorded. The cut-off of ankle-brachial index used to define patients with peripheral artery disease was ≤0.90. Results We studied 47 patients and found 24 patients (51%) who showed peripheral artery disease. As compared to patients without peripheral artery disease, patients with peripheral artery disease had lower values of peak oxygen uptake, peak workload, energy expenditure (metabolic equivalents) and heart rate recovery, but showed the same degree of airflow obstruction and static and dynamic hyperinflation. In a multivariate linear regression model performed to identify variables predicting metabolic equivalents, ankle-brachial index (β 2.59; 95% confidence interval 0.51-4.67; p = 0.016) was an independent variable. In the search for predictors of peripheral artery disease, heart rate recovery (odds ratio 8.80; 95% confidence interval 1.30-59.35; p = 0.026) increased the risk of peripheral artery disease, whereas metabolic equivalents (odds ratio 0.50; 95% confidence interval 0.26-0.94, p = 0.033) and inhaled corticosteroids+long-acting β 2 agonists (odds ratio 0.13; 95% confidence interval 0.02-0.83; p = 0.030) reduced this risk. Conclusions In chronic obstructive pulmonary disease outpatients, asymptomatic/silent peripheral artery disease affects the maximal exercise capacity regardless of airflow obstruction and lung hyperinflation. A delay of heart rate recovery increase the risk of peripheral artery disease, whereas high values of metabolic equivalents and the use of inhaled corticosteroids+long-acting β 2 agonists reduces this risk.

The effect of transcutaneous electrical nerve stimulation in patients with acute exacerbation of chronic obstructive pulmonary disease: randomised controlled trial.

The aim of the present study was to assess the efficacy of transcutaneous electrical nerve stimulation in patients with acute exacerbation of chronic obstructive pulmonary disease. In patients with stable chronic obstructive pulmonary disease, transcutaneous electrical nerve stimulation has been known to attain improvement in forced expiratory volume in 1 seconds, physical activity, and quality of life. However, information about the effects of transcutaneous electrical nerve stimulation on acute exacerbation of chronic obstructive pulmonary disease is quite limited. A single-blind, randomised controlled trial. Data were collected between August 2013-May 2014. Eighty-two patients who were hospitalised with a diagnosis of acute exacerbation of chronic obstructive pulmonary disease were randomly assigned to a transcutaneous electrical nerve stimulation group receiving transcutaneous electrical nerve stimulation treatment for 20 seance over the acupuncture points with pharmacotherapy or placebo group receiving the same treatment without electrical current output from the transcutaneous electrical nerve stimulation device. Pulmonary functional test, six-minute walking distance, dyspnoea and fatigue scale, and St. George's Respiratory Questionnaire scores were assessed pre- and postprogram. The program started at the hospital by the researcher was sustained in the patient's home by the caregiver. All patients were able to complete the program, despite the exacerbation. The 20 seance transcutaneous electrical nerve stimulation program provided clinically significant improvement in forced expiratory volume in 1 seconds 21 ml, 19·51% but when compared with the placebo group, the difference was insignificant (p > 0·05). The six-minute walking distance increased by 48·10 m more in the placebo group (p < 0·05). There were no significant differences between the two groups' St. George's Respiratory Questionnaire, dyspnoea and fatigue score (p > 0·05). Adding transcutaneous electrical nerve stimulation therapy to pharmacotherapy in patients with acute exacerbation of chronic obstructive pulmonary disease provided clinical improvement in forced expiratory volume in 1 seconds and add benefit in exercise capacity, but no significant effect on the other outcomes measured. Transcutaneous electrical nerve stimulation can be used as a non-invasive complementary therapy due to its beneficial effects on forced expiratory volume in 1 seconds and exercise capacity in patients with acute exacerbation of chronic obstructive pulmonary disease. © 2016 John Wiley & Sons Ltd.

Gastroenterological emergencies in the tropics.

Cook, G C

1991-12-01

Significant differences exist in the prevalence of most gastroenterological emergencies in tropical compared with temperate countries. Both ethnic and environmental (often clearly defined geographically) factors are relevant. The major oesophageal lesions which can present acutely in tropical countries are varices and carcinoma; bleeding and obstruction are important sequelae. Peptic ulcer disease (and its complications), often associated (not necessarily causally) with Helicobacter pylori infection, has marked geographical variations in incidence. Emergencies involving the small intestine are dominated by severe dehydration, and its sequelae, resulting from secretory diarrhoea, most notably cholera. However, enteritis necroticans ('pig bel' disease), paralytic ileus (sometimes caused by antiperistaltic agents) and obstruction (secondary to luminal helminths, volvulus and intussusception) are other important problems, especially in infants and children. Enteric fever is occasionally complicated by perforation and haemorrhage; the former (which is notoriously difficult to manage) is accompanied by significant mortality. Ileocaecal tuberculosis is a major cause of right iliac fossa pathology--sometimes associated with malabsorption; amoeboma is an important clinical differential diagnosis. The colon can be involved in invasive Entamoeba histolytica infection (which, like complicated enteric fever, is difficult to manage if the fulminant form, with perforation, ensues), shigellosis, volvulus and intussusception. Acute colonic dilatation occasionally follows Salmonella sp., Shigella sp., Campylobacter jejuni, Yersinia enterocolitica and rarely E. histolytica infections. Acute hepatocellular failure is a major cause of morbidity and mortality in the tropics and subtropics. It usually results from viral hepatitis (HBV, sometimes complicated by HDV, and HCV), but there is a long list of differential diagnoses. Hepatotoxicity resulting from herbs, chemotherapeutic agents or alcohol also occurs not infrequently. Chronic liver disease and its sequelae (often long-term results of viral hepatitis) are commonplace. Haematemesis and hepatocellular failure are usually very difficult to manage due to a lack of sophisticated support techniques in developing countries. Invasive hepatic amoebiasis usually responds well to medical management; however, spontaneous perforation can occur and the consequences of this are serious. Pyogenic liver abscess, although far less common than amoebic 'abscess', carries a bad prognosis whatever the method(s) of management. Hydatidosis and schistosomiasis also involve the liver, and helminthiases are important in the context of biliary tract disease. Gall stones are unusual in most tropical settings. Acute pancreatitis is overall unusual, but chronic calcific pancreatitis can present as an acute abdominal emergency.

Pulmonary hypertension in chronic obstructive pulmonary disease.

PubMed

Weitzenblum, Emmanuel; Chaouat, Ari; Kessler, Romain

2013-01-01

Pulmonary hypertension (PH) is a common complication of advanced chronic obstructive pulmonary disease (COPD) and is defined by a mean pulmonary artery pressure (PAP) ≥ 25 mm Hg at rest in the supine position. Owing to its frequency, COPD is a common cause of PH; in fact, it is the second most frequent cause of PH, just after left heart diseases. PH is due to the elevation of pulmonary vascular resistance, which is caused by functional and morphological factors, chronic alveolar hypoxia being the most important. In COPD PH is generally mild to moderate, PAP usually ranging between 25 and 35 mm Hg in a stable state of the disease. A small proportion of COPD patients may present a severe or "disproportionate" PH with a resting PAP > 35-40 mm Hg. The prognosis is particularly poor in these patients. In COPD PH worsens during exercise, sleep and severe exacerbations of the disease, and these acute increases in afterload may favour the development of right heart failure. The diagnosis of PH relies on Doppler echocardiography, and right heart catheterization is needed in a minority of patients. Treatment of PH in COPD relies on long-term oxygen therapy (≥ 16h/day) which generally stabilizes or at least attenuates the progression of PH. Vasodilator drugs, which are commonly used in idiopathic pulmonary arterial hypertension, have rarely been used in COPD, and we lack studies in this field. Patients with severe PH should be referred to a specialist PH centre where the possibility of inclusion in a controlled clinical trial should be considered.

Hepatic venous outflow tract obstruction (HVOTO) and extrahepatic portal venous obstruction (EHPVO) are important causes of portal hypertension and related complications in India. Both these conditions result from splanchnic venous thrombosis. In recent years, a V617F somatic mutation in Janus kinase 2 (JAK2) gene which is highly specific for myeloproliferative disorders has been detected in 40 % to 50 % and 30 % to 35 % of Western patients with HVOTO and EHPVO, respectively. However, data on this mutation in these conditions from Asian countries are limited. We looked for JAK2 V617F mutation in Indian patients with HVOTO (n = 40, median age 31 [range 17-51] years, 21 female) and EHPVO (n = 50, median age 23 [15-70] years, 25 female) by using two separate methods. Both the methods involved polymerase chain reaction using allele-specific primers. Positive results on one or both of these techniques were confirmed using DNA sequencing. None of the 40 patients with HVOTO and only 1 of 50 patients with EHPVO was found to have JAK2 V617F mutation. In the one patient who was found to have this mutation, both the PCR methods and DNA sequencing showed positive results. Hypercoagulability associated with JAK2 V617F mutation and associated chronic myeloproliferative disorders was not a major cause of HVOTO and EHPVO in this population.

We performed this observational prospective study to evaluate the results of the application of a diagnostic and therapeutic algorithm for complicated parapneumonic pleural effusion (CPPE) and pleural parapneumonic empyema (PPE). From 2001 to 2007, 210 patients with CPPE and PPE were confirmed through thoracocentesis and treated with pleural drainage tubes (PD), fibrinolytic treatment or surgical intervention (videothoracoscopy and posterolateral thoracotomy). Patients were divided into 3 groups: I (PD); II (PD and fibrinolytic treatment); IIIa (surgery after PD and fibrinolysis), and IIIb (direct surgery). The statistical study was done by variance analysis (ANOVA), χ2 and Fisher exact test. The presence of alcohol or drug consumption, smoking and chronic obstructive pulmonary disease (COPD) were strongly associated with a great necessity for surgical treatment. The IIIa group was associated with increased drainage time, length of stay and complications. No mortality was observed. The selective use of PD and intrapleural fibrinolysis makes surgery unnecessary in more than 75% of cases. The selective use of PD and fibrinolysis avoids surgery in more than 75% of cases. However, patients who require surgery have more complications, longer hospital stay, and more days on PD and they are more likely to require admittance to the Intensive Care Unit.

Chronic obstructive pulmonary disease (COPD) is actual pathology, when it forms the mixed hypoxemia. In the conditions of a chronic hypoxemia structures of organism with high level of metabolic processes, namely brain tissues, suffer. Character of defeat of the central nervous system at that pathology is insufficiently studied. In this article we studied and analysed the presence of such changes as depression, anxiety, cognitive impairment and features of neurologic semiotics at COPD in 50 patients.

2005-01-01

Limitation of exercise tolerance, especially activities of daily living, is the most significant clinical experience, which greatly affects quality of life of patients with chronic obstructive pulmonary disease (COPD). Many advances in the understanding of the pathophysiological mechanisms of bronchial obstruction in patients with COPD and their meanings for diagnosis and monitoring of the disease have occurred during the last two decades. The author discusses the most significant factors, which influence tolerance of physical exercise in patients with more advanced forms of COPD, and brings the attention to a practical test of physical capacity.

Although chronic obstructive pulmonary disease (COPD) has been implicated as a risk factor for abdominal aortic aneurysm (AAA) rupture, its effect on surgical repair is less defined. Consequently, variation in practice persists regarding patient selection and surgical management. The purpose of this study was to analyze the effect of COPD on patients undergoing AAA repair. We reviewed a prospective regional registry of 3455 patients undergoing elective open AAA repair (OAR) and endovascular AAA repair (EVAR) from 23 centers in the Vascular Study Group of New England from 2003 to 2011. COPD was categorized as none, medical (medically treated but not oxygen [O2]-dependent), and O2-dependent. End points included in-hospital death, pulmonary complications, major postoperative adverse events (MAEs), extubation in the operating room, and 5-year survival. Survival was determined using life-table analysis based on the Social Security Death Index. Predictors of in-hospital and long-term mortality were determined by multivariate logistic regression and Cox proportional hazards analysis. During the study interval, 2043 patients underwent EVAR and 1412 patients underwent OAR with a nearly equal prevalence of COPD (35% EVAR vs 36% OAR). O2-dependent COPD (4%) was associated with significantly increased in-hospital mortality, pulmonary complications, and MAE and was also associated with significantly decreased extubation in the operating room among patients undergoing both EVAR and OAR. Five-year survival was significantly diminished among all patients undergoing AAA repair with COPD (none, 78%; medical, 72%; O2-dependent, 42%; P < .001). By multivariate analysis, O2-dependent COPD was independently associated with in-hospital mortality (odds ratio 2.02, 95% confidence interval, 1.0-4.0; P = .04) and diminished 5-year survival (hazard ratio, 3.02; 95% confidence interval, 2.2-4.1; P < .001). Patients with O2-dependent COPD undergoing AAA repair suffer increased pulmonary complications, overall MAE, and diminished long-term survival. This must be carefully factored into the risk-benefit analysis before recommending elective AAA repair in these patients. Copyright © 2013 Society for Vascular Surgery. Published by Mosby, Inc.

Coronary ostia obstruction after replacement of aortic valve prostesis

PubMed Central

2011-01-01

Aortic valve replacement (AVR) is the gold standard for the treatment of severe symptomatic aortic stenosis. Complications directly related to surgical procedure are relatively infrequent. Coronary ostial stenosis is, generally, referred as late complication. Anecdotal reports concern coronary ostial stenosis as acute complication. A unique fatal case of intraoperative, bilateral coronary ostial obstruction by prosthetic valve leading to an extensive myocardial infarction is reported. Surgeons must have a high level of vigilance regarding the occurrence of acute myocardial ischemia and sudden death soon after AVR. PMID:21810231

The frequency and characteristics of headache in patients with chronic obstructive pulmonary disease (COPD) are not clear and there are only a few studies that have assessed the relationship between chronic hypoxaemia and headache. We performed this study in order to evaluate the frequency and characteristics of headache in COPD patients. A total of 119 patients, with a mean age of 63.4 +/- 8.2 years, diagnosed with moderate or severe stable COPD were included in the study. Overall 31.9% of the patients complained of headache and 45.4% were reported to have sleep disorders. There were significant effects of family history of COPD, having other systemic disorders or sleep disorders (snoring, bruxism, restless leg syndrome, etc.) and laboratory data of chronic hypoxaemia and airway obstruction on headache co-morbidity. In conclusion, possibly being a specific subtype of elderly headache, headache in patients with moderate or severe COPD is a common problem and future studies are needed to obtain more knowledge about its pathophysiological and clinical basis.

Current classifications of Chronic Obstructive Pulmonary Disease (COPD) severity are complex and do not grade levels of obstruction. Obstruction is a simpler construct and independent of ethnicity. We constructed an index of obstruction severity based on the FEV 1 /FVC ratio, with cut-points dividing the Burden of Obstructive Lung Disease (BOLD) study population into four similarly sized strata to those created by the GOLD criteria that uses FEV 1 . We measured the agreement between classifications and the validity of the FEV 1 -based classification in identifying the level of obstruction as defined by the new groupings. We compared the strengths of association of each classification with quality of life (QoL), MRC dyspnoea score and the self-reported exacerbation rate. Agreement between classifications was only fair. FEV 1 -based criteria for moderate COPD identified only 79% of those with moderate obstruction and misclassified half of the participants with mild obstruction as having more severe COPD. Both scales were equally strongly associated with QoL, exertional dyspnoea and respiratory exacerbations. Severity assessed using the FEV 1 /FVC ratio is only in moderate agreement with the severity assessed using FEV 1 but is equally strongly associated with other outcomes. Severity assessed using the FEV 1 /FVC ratio is likely to be independent of ethnicity.

To investigate the effect of partial bladder outlet obstruction on detrusor blood flow and oxygen tension (PdetO2) in female pigs. Detrusor-layer oxygen tension and blood flow were measured using oxygen-sensitive electrode and radiolabelled microsphere techniques in five female Large White pigs with a partial urethral obstruction and in five sham-operated controls. The effects of chronic outlet obstruction on bladder weight, and cholinergic nerve density and distribution, are also described. In the obstructed bladders, blood flow and oxygen tension were, respectively, 54.9% and 74.3% of control values at low bladder volume, and 47.5% and 42.5% at cystometric capacity. Detrusor blood flow declined by 27.8% and 37.5% in the control and obstructed bladders, respectively, as a result of bladder filling, whilst PdetO2 did not decrease in the controls, but fell by 42.7% in the obstructed bladders. Bladder weight increased whilst cholinergic nerve density decreased in the obstructed animals. In pigs with chronic bladder outlet obstruction, blood flow and oxygen tension in the detrusor layer were lower than in control animals. In addition, increasing detrusor pressure during filling caused significantly greater decreases in blood flow and oxygen tension in the obstructed than in the control bladders.

A recent American Thoracic Society and European Respiratory Society joint Task Force report recommends using a lower limit of normal (LLN) of forced expiratory volume in one second/forced vital capacity as opposed to a fixed ratio of <0.7 to diagnose airflow obstruction, in order to reduce false positive diagnoses of chronic obstructive pulmonary disease (COPD) as defined by the Global Initiative for Obstructive Lung Disease (GOLD). To date, there is no reliable spirometry-based prevalence data for COPD in New Zealand and the effect of different definitions of airflow obstruction based on post-bronchodilator spirometry is not known. Detailed written questionnaires, full pulmonary function tests (including pre- and post-bronchodilator flow-volume loops) and atopy testing were completed in 749 subjects recruited from a random population sample. The GOLD-defined, age-adjusted prevalence (95% confidence interval) for adults aged >or=40 yrs was 14.2 (11.0-17.0)% compared with an LLN-defined, age-adjusted, post-bronchodilator prevalence in the same group of 9.0 (6.7-11.3)%. The prevalence of chronic obstructive pulmonary disease varied markedly depending on the definition used. Further research using longitudinal rather than cross-sectional data will help decide the preferred approach in chronic obstructive pulmonary disease prevalence surveys.

Clinico-laboratory, functional and bronchoscopic examinations were performed in 120 patients with chronic obstructive pulmonary disease. 50 patients (41.7%) were in stage of low-intensity exacerbation, 70 patients (58.3%)--in remission stage. 55 patients (45.8%) had I degree respiratory failure, 65 patients (54.2%)--II degree respiratory failure. Easy degree of disease was detected in 58 patients (48.3%), mid degree--in 62 patients (51.7%). Possibility and reasonability of the use of artificial sylvinite speleotherapy and general chloride sodium baths in patients with chronic obstructive pulmonary disease were proved. Clinical results were confirmed by data of blood morphology and biochemical analysis, microscopy of sputum, spirometry, bronchoscopy, dynamics of immunological indices.

Understanding how European care of chronic obstructive pulmonary disease (COPD) admissions vary against guideline standards provides an opportunity to target appropriate quality improvement interventions. In 2010-2011 an audit of care against the 2010 'Global initiative for chronic Obstructive Lung Disease' (GOLD) standards was performed in 16 018 patients from 384 hospitals in 13 countries. Clinicians prospectively identified consecutive COPD admissions over a period of 8 weeks, recording clinical care measures on a web-based data tool. Data were analysed comparing adherence to 10 key management recommendations. Adherence varied between hospitals and across countries. The lack of available spirometry results and variable use of oxygen and non-invasive ventilation (NIV) are high impact areas identified for improvement.

The four main diagnostic groups for palliative care provision are cancer, chronic obstructive pulmonary disease, heart failure and dementia. But comparisons of costs and care in the last year of life are mainly directed at cancer versus non-cancer or within cancer patients. Our aim is to compare the care and expenditures in their last year of life for Dutch patients with cancer, chronic obstructive pulmonary disease, heart failure or dementia. Data from insurance company Achmea (2009-2010) were linked to information on long-term care at home or in an institution, the National Hospital Registration and Causes of Death-Registry from Statistics Netherlands. For patients who died of cancer ( n = 8658), chronic obstructive pulmonary disease ( n = 1637), heart failure ( n = 1505) or dementia ( n = 3586), frequencies and means were calculated, Lorenz curves were drawn up and logistic regression was used to compare patients with high versus low expenditures. For decedents with cancer and chronic obstructive pulmonary disease, the highest costs were for hospital admissions. For decedents with heart failure, the highest costs were for the care home (last 360 days) and hospital admissions (last 30 days). For decedents with dementia, the highest costs were for the nursing home. Patients with dementia had the highest expenditures due to nursing home care. The number of dementia patients will double by the year 2030, resulting in even higher economic burdens than presently. Policy regarding patients with chronic conditions should be informed by research on expenditures within the context of preferences and needs of patients and carers.

Contact laser prostatectomy in a patient on chronic anticoagulation

1995-05-01

The `gold standard' therapy for patients with symptomatic bladder outlet obstruction secondary to benign prostatic hyperplasia has always been electrocautery TURP. However, in patients with medical problems requiring chronic anticoagulation, this procedure is contraindicated due to the extreme risk of hemorrhage, both during the procedure and the immediate post operative period. With the recent development of contact laser prostatectomy the patient on chronic anticoagulation can safely undergo the procedure. Herein, I present a case of a 60 year old with significant bladder outlet obstruction yielding an AUA symptom score of 18. The patient had a history of multiple episodes of deep venous thrombosis of the left leg with three prior pulmonary emboli. He was maintained on chronic anticoagulation with alternating days of 3.5 mg. and 5.0 mg. of warfarin sodium (coumadin). Preoperative cystoscopy showed a 4 cm prostatic fossa obstructed by tri-lobar hypertrophy, with large kissing lateral lobes and visual obstruction from the verumontanum. The patient underwent a contact laser prostatectomy with the SLT Nd:YAG laser at 50 watts. There was minimal bleeding both during the procedure and in the immediate postoperative period. At three months post-op the AUA symptom score had decreased to 2. This case demonstrated that contact laser prostatectomy can be safely and effectively performed in patients on chronic anticoagulation.

The appendix inflammatory process is the most common cause of chronic abdominal pain in the right lower quadrant. The frequency of appendiceal lumen obstruction by fecalith ranges from 10 to 20%; few cases of obstruction by multiple fecaliths had been reported. Sixty-nine years old male, diabetic and hypertensive in control, he underwent bowel resection 30 years previously. He completed 6 months with intermittent, mild pain in the right lower quadrant abdomen; 14 days prior to admission with increasing pain, nausea, vomiting, constipation, abdominal distension and absence of peristalsis; 12,750 leukocytes, neutrophils 90%; plain abdominal radiography without specific bowel pattern, TAC with 3 dense images in right lower quadrant; exploratory laparotomy was performed and perforated appendix with 3 free fecaliths was found. Histopathological report showed fibrosis and lymphocytic infiltrate in the muscle layer of the cecal appendix consistent with chronic appendicitis. The most common obstruction of the appendix lumen is by a single fecalith. In this case the patient had chronic appendicitis secondary to appendiceal lumen obstruction by multiple fecaliths. Reviewing the international literature any case of chronic appendicitis associated with the presence of multiple fecaliths was found. Copyright © 2016 Academia Mexicana de Cirugía A.C.

Three-dimensional computed tomography (3D-CT) enables in vivo volumetry of total lung volume (TLV) and emphysematous low-attenuation volume (LAV) in patients with chronic obstructive pulmonary disease (COPD). We retrospectively investigated the correlation between preoperative 3D-CT volumetry and postoperative complications in lung cancer patients. We searched our institution's surgical records from December 2006 to December 2009 and selected patients who had undergone pulmonary lobectomy for primary lung cancer. From 3D-CT data, TLV and LAV <-950 HU of thresholds were retrospectively measured. The LAV% was calculated as follows: LAV% = LAV/TLV*100. The associations between the seven independent variables (LAV%, age, gender, body mass index, smoking history, forced expiratory volume in 1 second as percent forced vital capacity [FEV1%], and resected lobe) and the two outcomes (postoperative complications and prolonged postoperative stay [PPS]) were compared using logistic regression analysis. A total of 309 patients (222 males, 87 females; mean age, 67 years; range, 40-87 years) were evaluated. On multivariate analysis, age and LAV% were significantly correlated with postoperative complications (p = 0.006 and p = 0.006, respectively), and LAV% was significantly correlated with PPS (p = 0.031). LAV% measured using 3D-CT is more sensitive for predicting complications after lobectomy for lung cancer than FEV1%.

Acute appendicitis with unusual dual pathology.

Riddiough, Georgina E; Bhatti, Imran; Ratliff, David A

2012-01-01

Meckel's diverticulum is a rare congenital abnormality arising due to the persistence of the vitelline duct in 1-3% of the population. Clinical presentation is varied and includes rectal bleeding, intestinal obstruction, diverticulitis and ulceration; therefore diagnosis can be difficult. We report a case of acute appendicitis complicated by persistent post operative small bowel obstruction. Further surgical examination of the bowel revealed an non-inflamed, inverted Meckel's diverticulum causing intussusception. Intestinal obstruction in patients with Meckel's diverticulum may be caused by volvulus, intussusception or incarceration of the diverticulum into a hernia. Obstruction secondary to intussusception is relatively uncommon and frequently leads to a confusing and complicated clinical picture. Consideration of Meckel's diverticulum although a rare diagnosis is imperative and this case raises the question "should surgeons routinely examine the bowel for Meckel's diverticulum at laparoscopy?"

Pulmonary complications of cystic echinococcosis in children in Uruguay.

2005-08-01

Cystic echinococcal lesions surgically removed from 99 patients aged 1-15 years in Uruguay were histopathologically studied. The lesions were collected from the lungs, liver, peritoneum, omentum, pleura, ovary, appendix and perinephrium. All intact cysts were well-developed and unilocular. Pulmonary and hepatic fertile cysts in which protoscoleces were produced were in 75% and 47%, respectively, of all patients. Fertile cysts having many protoscoleces were in the lungs of a 1-year-old infant. Sixteen ruptured pulmonary cysts were found in the lungs of 13 patients and four ruptured hepatic cysts were found in the liver of three patients. Pulmonary complications were seen in patients having pulmonary echinococcal cysts. In lung tissue surrounding echinococcal cysts, pulmonary complications included chronic congestion, hemorrhage, bronchopneumonia, as well as interstitial pneumonia that included histological changes caused by bronchiolitis, organizing pneumonia and obstructive pneumonia. Liver tissue adjacent to echinococcal cysts showed atrophy of hepatic cells, proliferation of interstices, small focal hemorrhages, and infiltration of mononuclear cells. The present study shows that a close relationship exists between pulmonary echinococcosis and pneumonia. The term 'echinococcal pneumonia' is proposed for pneumonia accompanying pulmonary echinococcosis.

Deep venous thrombosis and postthrombotic syndrome: invasive management.

Comerota, A J

2015-03-01

Invasive management of postthrombotic syndrome encompasses the two ends of the deep vein thrombosis spectrum, patients with acute iliofemoral deep vein thrombosis and those with chronic postthrombotic iliofemoral venous obstruction. Of all patients with acute deep vein thrombosis, those with involvement of the iliofemoral segments have the most severe chronic postthrombotic morbidity. Catheter-based techniques now permit percutaneous treatment to eliminate thrombus, restore patency, potentially maintain valvular function, and improve quality of life. Randomized trial data support an initial treatment strategy of thrombus removal. Failure to eliminate acute thrombus from the iliofemoral system leads to chronic postthrombotic obstruction of venous outflow. Debilitating chronic postthrombotic symptoms of the long-standing obstruction of venous outflow can be reduced by restoring unobstructed venous drainage from the profunda femoris vein to the vena cava. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

It was the aim of this prospective study to evaluate the outcome of laparoscopic surgery for diverticular disease. All patients who underwent elective laparoscopic colectomy for diverticular disease within a 10-year period were prospectively entered into a PC database registry. Indications for laparoscopic surgery were acute complicated diverticulitis (Hinchey stages I and IIa), chronically recurrent diverticulitis, sigmoid stenosis or outlet obstruction caused by chronic diverticulitis. Surgical procedures (sigmoid and anterior resection, left colectomy and resection rectopexy) included intracorporeal dissection and colorectal anastomosis. Parameters studied included age, gender, stage of disease, procedure, duration of surgery, intraoperative technical variables, transfusion requirements, conversion rate, total complication rate including major (requiring re-operation), minor (conservative treatment) and late-onset (post-discharge) complication rates, stay on ICU, hospitalisation, mortality, and recurrence. For objective evaluation, only laparoscopically completed procedures were analysed. Comparative outcome analysis was performed with respect to stage of disease and experience. A total of 396 patients underwent laparoscopic colectomy. Conversion rate was 6.8% ( n=27), so that laparoscopic completion rate was 93.2% ( n=369). Most common reasons for conversion were directly related to the inflammatory process, abscess or fistulas. The most common procedure was sigmoid resection ( n=279), followed by anterior resection ( n=36) and left colectomy ( n=29). Total complication rate was 18.4% ( n=68). Major complication rate was 7.6% ( n=28), whereas the most common complication requiring re-operation was haemorrhage in 3.3% ( n=12). Anastomotic leakage occurred in 1.6% ( n=6). Minor complications were noted in 10.7% ( n=40), late-onset complications occurred in 2.7% ( n=10). Mortality was 0.5% ( n=2). Mean duration of surgery was 193 (range 75-400) min, return to normal diet was completed after 6.8 (range 3-19) days. Mean hospital stay was 11.8 (range 4-71) days. No recurrence of diverticulitis occurred. Laparoscopic surgery for diverticular disease is safe, feasible and effective. Therefore, laparoscopic colectomy has replaced open resection as standard surgery for recurrent and complicated diverticulitis at our institution.

To review long-term respiratory effects of mustard gas on Iranian veterans having undergone Iraq-Iran war. Electronic databases of Scopus, Medline, ISI, IranMedex, and Irandoc sites were searched. We accepted articles published in scientific journals as a quality criterion.The main pathogenic factors are free radical mediators. Prevalence of pulmonary involvement is approximately 42.5%. The most common complaints are cough and dyspnea. Major respiratory complications are chronic obstructive pulmonary disease, bronchiectasis, and asthma. Spirometry results can reveal restrictive and obstructive pulmonary disease. Plain chest X-ray does not help in about 50% of lung diseases. High-resolution CT of the lung is the best modality for diagnostic assessment of parenchymal lung and bronchi. There is no definite curative treatment for mustard lung. The effective treatment regimens consist of oxygen administration, use of vaporized moist air, respiratory physiotherapy, administration of mucolytic agents, bronchodilators, corticosteroids, and long-acting beta-2 agonists, antioxidants, surfactant, magnesium ions, therapeutic bronchoscopy, laser therapy, placement of respiratory stents, early tracheostomy in laryngospasm, and ultimately lung transplantation. High-resolution CT of the lung is the most accurate modality for the evaluation of the lung parenchyma and bronchi. The treatment efficacy of patients exposed to mustard gas depends on patient conditions (acute or chronic, upper or lower respiratory tract involvement). There are various treatment protocols, but unfortunately none of them is definitely curable.

Cigarette smoking contributes to the development of pulmonary hypertension (PH) complicated with chronic obstructive pulmonary disease (COPD), and the pulmonary vascular remodeling, the structural basis of PH, could be attributed to abnormal proliferation of pulmonary artery smooth muscle cells (PASMCs).In this study, morphometrical analysis showed that the pulmonary vessel wall thickness in smoker group and COPD group was significantly greater than in nonsmokers. In addition, we determined the expression patterns of connective tissue growth factor (CTGF) and cyclin D1 in PASMCs harvested from smokers with normal lung function or mild to moderate COPD, finding that the expression levels of CTGF and cyclin D1 were significantly increased in smoker group and COPD group. In vitro experiment showed that the expression of CTGF, cyclin D1 and E2F were significantly increased in human PASMCs (HPASMCs) treated with 2% cigarette smoke extract (CSE), and two CTGF siRNAs with different mRNA hits successfully attenuated the upregulated cyclin D1 and E2F, and significantly restored the CSE-induced proliferation of HPASMCs by causing cell cycle arrest in G0. These findings suggest that CTGF may contribute to the pathogenesis of abnormal proliferation of HPASMCs by promoting the expression of its downstream effectors in smokers with or without COPD.

The incidence of chronic obstructive pulmonary disease (COPD) is on the rise worldwide. Chronic bronchitis is a frequent accompaniment of COPD, which increases the burden of COPD in affected individuals. The aim of this study was to characterize the phenotype of chronic bronchitis in COPD patients. The study was based on the survey data retrospectively retrieved from the Action Health-Lung Cancer Prophylaxis and Health Care Improvement screening program that concerned all the inhabitants, aged over 40, of the Proszowice administrative region situated in the Lesser Poland Voivodeship in southern Poland. Participants with the symptoms suggestive of a lung disease were subject to further evaluation. The findings were that 546 (13.3%) out of the 4105 individuals displayed spirometry features of COPD. Symptoms of chronic bronchitis were present in 92 (16.8%) out of the COPD afflicted persons. Chronic bronchitis was commoner in current smokers and its incidence increased with increasing severity of airway obstruction. In multivariate analysis, chronic bronchitis was independently related to lower FEV1, FVC, FEV1/FVC, and to dyspnea. In regression model, factors related to increased risk of chronic bronchitis were current smoking, asthma, and lower lung function. We conclude that COPD with coexisting chronic bronchitis is linked to severer dyspnea and worse lung function. Current smoking, asthma, and lower lung function are related to increased risk of chronic bronchitis accompanying COPD.

Abstract Chronic diseases in most cases belong to the category of non-communicable diseases (NCDs), which are the main cause of mortality globally. Cardiovascular diseases, diabetes, chronic obstructive pulmonary disease and cancer are the four NCDs responsible for 82% of NCD deaths. Prevention of NCDs implies health promotion activities that encourage healthy lifestyle and limit the initial onset of chronic diseases. Prevention also includes early detection activities, such as screening at-risk populations, as well as strategies for appropriate management of existing diseases and related complications. Early intervention, reducing morbidity and mortality rates could be an appealing idea for patients, physicians and governmental institutions but could also cause harm. Healthcare is undergoing profound changes, and the role of technology in diagnostics and management of chronic diseases in primary healthcare (PHC) is increasing remarkably. However, studies show that the standards of care for chronic diseases and preventive care are met by less than 50%. We still lack clear standards for patients with multiple chronic diseases. The applicability of a single evidence-based guideline to multimorbid patients is limited and can be problematic. Well-designed PHC studies focusing on the impact of medical interventions on morbidity, mortality and quality of life in the fields of early diagnosis, early treatment and multimorbidity are still needed.

2015-01-01

This retrospective study was a comparative analysis of sensitivity of impulse oscillometry and spirometry techniques for use in a mixed chronic obstructive pulmonary disease group for assessing disease severity and inhalation therapy. A total of 30 patients with mild-to-moderate chronic obstructive pulmonary disease were monitored by impulse oscillometry, followed by spirometry. Lung function was measured at baseline after bronchodilation and at follow-up (3-18 months). The impulse oscillometry parameters were resistance in the small and large airways at 5 Hz (R5), resistance in the large airways at 15 Hz (R15), and lung reactance (area under the curve X; AX). After the bronchodilator therapy, forced expiratory volume in 1 second (FEV1) readings evaluated by spirometry were unaffected at baseline and at follow-up, while impulse oscillometry detected an immediate improvement in lung function, in terms of AX (p = 0.043). All impulse oscillometry parameters significantly improved at follow-up, with a decrease in AX by 37% (p = 0.0008), R5 by 20% (p = 0.0011), and R15 by 12% (p = 0.0097). Impulse oscillometry parameters demonstrated greater sensitivity compared with spirometry for monitoring reversibility of airway obstruction and the effect of maintenance therapy. Impulse oscillometry may facilitate early treatment dose optimization and personalized medicine for chronic obstructive pulmonary disease patients.

SUMMARY Obstructive sialadenitis is the most common non-neoplastic disease of the salivary glands, and sialendoscopy is increasingly used in both diagnosis and treatment, associated in selected cases with endoscopic laser lithotripsy. Sialendoscopy is also used for combined minimally invasive external and endoscopic approaches in patients with larger and proximal stones that would require excessively long laser procedures. The present paper reports on the technical experience from the Ear, Nose and Throat Unit of the Sant'Orsola-Malpighi Hospital of Bologna, and from the Department of Otorhinolaryngology of the University Hospital of Cagliari, Italy, including the retrospective analysis of the endoscopic and endoscopic assisted procedures performed on 48 patients (26 females and 22 males; median age 45.3; range 8-83 years) treated for chronic obstructive sialadenitis at the University Hospital of Cagliari from November 2010 to April 2016. The results from the Sant'Orsola-Malpighi Hospital of Bologna have been previously published. The technical aspects of sialendoscopy are carefully described. The retrospective analysis of the University Hospital of Cagliari shows that the disease was unilateral in 40 patients and bilateral in 8; a total of 56 major salivary glands were treated (22 submandibular glands and 34 parotids). Five patients underwent bilateral sialendoscopy for juvenile recurrent parotitis. 10 patients were treated for non-lithiasic obstructive disease. In 33 patients (68.75%) the obstruction was caused by salivary stones (bilateral parotid lithiasis in 1 case). Only 8 patients needed a sialectomy (5 submandibular glands and 3 parotids). The conservative approach to obstructive sialadenitis is feasible and can be performed either purely endoscopically or in a combined modality, with a high percentage of success. The procedure must be performed with dedicated instrumentation by a skilled surgeon after proper training since minor to major complications can be encountered. Sialectomy should be the "extrema ratio" after failure of a conservative approach. PMID:28516972

Airway mucus, inflammation and remodeling: emerging links in the pathogenesis of chronic lung diseases.

Airway mucus obstruction is a hallmark of many chronic lung diseases including rare genetic disorders such as cystic fibrosis (CF) and primary ciliary dyskinesia, as well as common lung diseases such as asthma and chronic obstructive pulmonary disease (COPD), which have emerged as a leading cause of morbidity and mortality worldwide. However, the role of excess airway mucus in the in vivo pathogenesis of these diseases remains poorly understood. The generation of mice with airway-specific overexpression of epithelial Na + channels (ENaC), exhibiting airway surface dehydration (mucus hyperconcentration), impaired mucociliary clearance (MCC) and mucus plugging, led to a model of muco-obstructive lung disease that shares key features of CF and COPD. In this review, we summarize recent progress in the understanding of causes of impaired MCC and in vivo consequences of airway mucus obstruction that can be inferred from studies in βENaC-overexpressing mice. These studies confirm that mucus hyperconcentration on airway surfaces plays a critical role in the pathophysiology of impaired MCC, mucus adhesion and airway plugging that cause airflow obstruction and provide a nidus for bacterial infection. In addition, these studies support the emerging concept that excess airway mucus per se, probably via several mechanisms including hypoxic epithelial necrosis, retention of inhaled irritants or allergens, and potential immunomodulatory effects, is a potent trigger of chronic airway inflammation and associated lung damage, even in the absence of bacterial infection. Finally, these studies suggest that improvement of mucus clearance may be a promising therapeutic strategy for a spectrum of muco-obstructive lung diseases.

To analyse the incidence of thrombosis and obstruction associated with central venous lines (CVL) inserted in critically ill children, and to determine their risk factors. Prospective observational study in a Pediatric Intensive Care Unit in a University Hospital. An analysis was made of 825 CVL placed in 546 patients. Age, gender, weight, type of catheter (lines, size, and brand), final location of the catheter, mechanical ventilation, type of sedation and analgesia used, initial failure by the doctor to perform CVL catheterization, number of attempts, CVL indication, admission diagnosis, emergency or scheduled procedure, and delayed mechanical complications (DMC). Risk factors for these complications were determined by a multiple regression analysis. A total of 52 cases of DMC, 42 cases of obstruction, and 10 of thrombosis were registered. Obstruction and thrombosis rates were 4.96 and 1.18 per 100 CVL, respectively. The only risk factor independently linked to obstruction was the duration of the CVL (OR 1.05; 95% CI; 1.00-1.10). The number of lines with thrombosis (OR 4.88; 95% CI; 1.26-18.0), as well as parenteral nutrition (OR 4.17; 95% CI; 1.06-16.31) was statistically significant according to bivariate analysis. However, no risk factors for thrombosis were found in the multivariate analysis. Obstruction and thrombosis of CVL inserted in a Pediatric Intensive Care Unit are relatively common complications. CVL duration is an independent risk factor for any line obstruction. Copyright © 2012 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

Acute Exacerbation of Chronic Obstructive Pulmonary Disease: Cardiovascular Links

PubMed Central

Laratta, Cheryl R.; van Eeden, Stephan

2014-01-01

Chronic obstructive pulmonary disease (COPD) is a chronic, progressive lung disease resulting from exposure to cigarette smoke, noxious gases, particulate matter, and air pollutants. COPD is exacerbated by acute inflammatory insults such as lung infections (viral and bacterial) and air pollutants which further accelerate the steady decline in lung function. The chronic inflammatory process in the lung contributes to the extrapulmonary manifestations of COPD which are predominantly cardiovascular in nature. Here we review the significant burden of cardiovascular disease in COPD and discuss the clinical and pathological links between acute exacerbations of COPD and cardiovascular disease. PMID:24724085

Hack, Henrik

2014-01-01

Children with Sleep Disordered Breathing/Obstructive Sleep Apnoea have an increased incidence of respiratory complications following adenotonsillectomy. This may be partly related to an increase in sensitivity to opiates. An audit of such cases undergoing adenotonsillectomy was performed with the following aims: All patients had Sleep Disordered Breathing/Obstructive Sleep Apnoea confirmed preoperatively by Overnight Oximetry Studies. Oximetry data was expressed as the lowest recorded saturation (SpO2 Low %) and number of significant desaturations (see text) per hour (ODI4%). Case notes and oximetry studies were scrutinized for relevant perioperative anaesthetic and analgesic data, risk factors and complications. The overall incidence of major and minor respiratory complications was low (1.6% and 27% respectively). Children who suffered any complication were more likely to be younger (p=0.0078), have a lower SpO2 Low (p=0.004) and higher ODI4% (p=<0.0001). Multiple logistic regression showed ODI4% to be the best predictor of a potential respiratory complication (p=0.0032). An ODI4% of >8 may be the best cut off point in predicting complications (AUC=0.78, sensitivity=0.90) but it showed a poor specificity (0.57). Primary/secondary haemorrhage occurred in 0.4%/1.2% respectively and postoperative nausea and vomiting in 4.4%. A low dose opiate-based, multi modal analgesic regime appears to be effective and safe in children with Sleep Disordered Breathing/Obstructive Sleep Apnoea undergoing adenotonsillectomy.

In this case report, we describe the use of the Draeger Apollo anesthesia machine to deliver bilevel positive airway pressure (BiPAP) to a patient with severe chronic obstructive pulmonary disease and a history of lung resection undergoing frontal craniotomy for the removal of a brain tumor under moderate to deep sedation. BiPAP in the perioperative period has been described for purposes of preoxygenation and postextubation recruitment. Although its utility as a mode of ventilation during moderate to deep sedation has been demonstrated, it has not come into widespread use. We describe the intraoperative use of pressure support mode on the anesthesia machine to deliver noninvasive positive pressure ventilation through a standard anesthesia mask. Given its ease of access and effectiveness, it is our belief that intraoperative BiPAP may reduce hypoxemia and/or hypercarbia in patients with chronic obstructive pulmonary disease and obstructive sleep apnea undergoing moderate to deep sedation.

To examine the effect of whole-body vibration in enhancing pulmonary function, functional exercise capacity and quality of life in people with chronic obstructive pulmonary disease and examine its safety. Randomized controlled trials examining the effects of whole body vibration among people with chronic obstructive pulmonary disease were identified by two independent researchers. Articles were excluded if they were studies on people with other primary diagnosis, abstracts published in the conferences or books. PEDro scale was used to assess the methodological quality of the selected studies. We evaluated the level of evidence by using the GRADE approach. The results were extracted by two researchers and confirmed by the third researcher if disagreement existed. Sources included Cochrane Central Register of Controlled Trials, PubMed, CINAHL, EMBASE, PEDro, AMED, PsycINFO, ClinicalTrials.gov, Current Controlled Trials and reference lists of all relevant articles. Four studies involving 206 participants were included in this systematic review. Methodological quality was rated as good for two studies. No great benefits on pulmonary function were found in whole body vibration treatment group. Two studies showed that quality of life was improved in people with chronic obstructive pulmonary disease. Whole body vibration led to significant improvements in functional exercise capacity measured with six minutes walking test. Nearly no adverse events were observed. Whole body vibration may improve functional exercise capacity and quality of life in people with chronic obstructive pulmonary disease. There was insufficient evidence to prove the effects of whole body vibration on pulmonary function. © The Author(s) 2015.

Fleet enema (sodium phosphate, C.B. Fleet Co., Inc., Lynchburg, Virginia) is widely used for bowel preparation or constipation relief in the hospital and over the counter. The potential risks, including hyperphosphatemia and hypocalcemic coma should be kept in mind of primary care physician. The patients with older age, bowel obstruction, small intestinal disorders, poor gut motility, and renal disease are contraindicated or should be administered with caution. We present a patient with old age and chronic renal failure who developed severe hyperphosphatemia and hypocalcemic tetany with coma after sodium phosphate enema. We recommend the use of alternative enema preparations, such as simple tap water or saline solution enemas, which can prevent fatal complications in high risk patients.

Chronic Obstructive Pulmonary Disease: Diagnosis and Management.

PubMed

Gentry, Shari; Gentry, Barry

2017-04-01

The diagnosis of chronic obstructive pulmonary disease (COPD) should be suspected in patients with risk factors (primarily a history of smoking) who report dyspnea at rest or with exertion, chronic cough with or without sputum production, or a history of wheezing. COPD may be suspected based on findings from the history and physical examination, but must be confirmed by spirometry to detect airflow obstruction. Findings that are most helpful to rule in COPD include a smoking history of more than 40 pack-years, a self-reported history of COPD, maximal laryngeal height, and age older than 45 years. The combination of three clinical variables-peak flow rate less than 350 L per minute, diminished breath sounds, and a smoking history of 30 pack-years or more-is another good clinical predictor, whereas the absence of all three of these signs essentially rules out airflow obstruction. Pharmacotherapy and smoking cessation are the mainstays of treatment, and pulmonary rehabilitation, long-term oxygen therapy, and surgery may be considered in select patients. Current guidelines recommend starting monotherapy with an inhaled bronchodilator, stepping up to combination therapy as needed, and/or adding inhaled corticosteroids as symptom severity and airflow obstruction progress.

2017-12-01

Neuromuscular diseases include a wide range of conditions that may involve potentially life-threatening respiratory complications (infection, respiratory failure). For patients with neuromuscular diseases, clinical assessment of respiratory function and regular pulmonary function tests are needed to screen for nocturnal respiratory disorders, weakness of the diaphragm and potential restrictive disorders and/or chronic hypercapnic respiratory insufficiency, possibly with couch deficiency. MANAGEMENT OF NOCTURNAL RESPIRATORY DISORDERS AND CHRONIC RESPIRATORY FAILURE: Nocturnal respiratory assistance is an important phase of care for nocturnal respiratory disorders and chronic respiratory failure. This may involve continuous positive airway pressure, adaptative servo-ventilation or non-invasive ventilation with a facial or nasal mask. As needed, diurnal assistance may be proposed by mouthpiece ventilation. Should non-invasive ventilation prove insufficient, or if significant swallowing disorders or recurrent bronchial obstruction develop, or in case of prolonged intubation, tracheotomy may be required. In case of lower airway infection with ineffective cough, physical therapy, associated with air stacking, intermittent positive pressure breathing or mechanical in-exsufflation may be proposed. Care for swallowing disorders, nutritional counseling (cachexia, obesity), vaccinations and therapeutic education are integral elements of patient-centered management aiming to prevent the negative impact of infection and to manage respiratory failure of chronic neuromuscular disease.

Future of chronic obstructive pulmonary disease management.

PubMed

D'Urzo, Anthony; Vogelmeier, Claus

2012-06-01

Bronchodilators play a pivotal role in the management of symptomatic chronic obstructive pulmonary disease. Inhaled short-acting bronchodilators are used for all stages of chronic obstructive pulmonary disease, primarily for the immediate relief of symptoms; inhaled long-acting bronchodilators are recommended for maintenance therapy in patients with moderate-to-very severe disease and those with daily symptoms. When symptoms are not adequately controlled by a single bronchodilator, combining bronchodilators of different classes may prove effective. Several long-acting β(2)-agonists and long-acting muscarinic antagonists with 24-h duration of action and inhalers combining different classes of long-acting, once-daily bronchodilators are in development. The place of these agents in the treatment algorithm will be determined by their efficacy and safety profiles and their long-term impact on relevant clinical outcomes.

Japan is an aging society, and the number of elderly patients with asthma and chronic obstructive pulmonary disease (COPD) is consequently increasing, with an estimated incidence of approximately 5 million. In 2014, asthma-COPD overlap syndrome (ACOS) was defined by a joint project of Global Initiative for Asthma (GINA) committee and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) committee. The main aims of this consensus-based document are to assist clinicians, especially those in primary care or nonpulmonary specialties. In this article, we discussed parameters to differentiate asthma and COPD in elderly patients and showed prevalence, clinical features and treatment of ACOS on the basis of the guidelines of GINA and GOLD. Furthermore, we showed also referral for specialized investigations.

Prevention of internal hernias and pelvic adhesions following laparoscopic left-sided colorectal resection: the role of fibrin sealant.

Laparoscopy has increasingly become the standard of care for patients who undergo colorectal surgery for both benign and malignant diseases. This growing experience has also resulted in more reports of postoperative complications from the minimally invasive approach to primary colorectal resection. Small bowel obstruction from internal hernias and pre-sacral adhesions is an uncommon but not negligible complication. However, there is little literature specific to this topic with recommendations for different methods to prevent it. We report our original technique of closing the mesenteric defect and covering the pre-sacral fascia by using fibrin sealant to prevent this complication. From January 2005 to December 2014, a total of 1079 patients underwent elective laparoscopic left colorectal resection (left hemicolectomy or anterior rectal resection) in our department. In the first 298 procedures, the mesenteric defect was left open, while in the following 781 procedures, it was closed using fibrin sealant with the aim of preventing postoperative small bowel obstruction. Among the first 298 patients, three (1%) required reoperation for small bowel obstruction due to internal hernia (0.33%) or critical pre-sacral adhesions (0.66%). These complications did not occur in the subsequent series in which all 781 patients were treated with fibrin sealant prophylactic closure of the mesenteric defect. In our experience, fibrin sealant closure of the mesenteric defect has demonstrated to be safe and effective in preventing postoperative small bowel obstruction that remains a complication both in open and in laparoscopic colorectal surgeries.

[Correlation between obstructive apnea syndrome and difficult airway in ENT surgery].

ENT patients with obstructive sleep apnea syndrome have a tendency of collapsing the upper airways in addition to anatomical obstacles. Obstructive sleep apnea syndrome is related to the increased risk of difficult airway and also increased perioperative complications. In order to identify these patients in the preoperative period, the STOP Bang questionnaire has been highlighted because it is summarized and easy to apply. Evaluate through the STOP Bang questionnaire whether patients undergoing ENT surgery with a diagnosis of obstructive sleep apnea syndrome have a higher risk of complications, particularly the occurrence of difficult airway. Measurements of anatomical parameters for difficult airway and questionnaire application for clinical prediction of obstructive sleep apnea syndrome were performed in 48 patients with a previous polysomnographic study. The sample detected difficult airway in about 18.7% of patients, all of them with obstructive sleep apnea syndrome. This group had older age, cervical circumference > 40cm, ASA II and Cormack III/IV. Patients with obstructive sleep apnea syndrome had higher body mass index, cervical circumference, and frequent apnea. In subgroup analysis, the group with severe obstructive sleep apnea syndrome showed a significantly higher SB score compared to patients without this syndrome or with a mild/moderate obstructive sleep apnea syndrome. The STOP Bang questionnaire was not able to predict difficult airway and mild obstructive sleep apnea syndrome, but it identified marked obstructive sleep apnea syndrome. All patients with difficult airway had moderate and marked obstructive sleep apnea syndrome, although this syndrome did not involve difficult airway. The variables Cormack III/IV and BMI greater than 35 Kg.m -2 were able to predict difficult airway and obstructive sleep apnea syndrome, respectively.

To improve the results of obstructive jaundice management by rational diagnostic and treatment strategies. Outcomes of 820 patients with obstructive jaundice syndrome were analyzed. Diagnostic and tactical mistakes were made at pre-hospital stage in 143 (17.4%) patients and in 105 (12.8%) at hospital stage. Herewith, in 53 (6.5%) cases the errors were observed at all stages. Retrospective analysis of severe postoperative complications and lethal outcomes in patients with obstructive jaundice showed that in 23.8% of cases they were explained by diagnostic and tactical mistakes at various stages of examination and treatment. We developed an algorithm for obstructive jaundice management to reduce the number of diagnostic and tactical errors, a reduction in the frequency of diagnostic and tactical errors. It reduced the number of postoperative complications up to 16.5% and mortality rate to 3.0%.

Left ventricular outflow tract (LVOT) obstruction and paravalvular leak (PVL) are relatively uncommon, but are serious complications of prosthetic valve replacement. We present a case that displays the unique therapeutic challenges of treating a patient who developed both LVOT obstruction and mitral PVL after undergoing surgical aortic and mitral valve replacement (MVR). We also describe the use of alcohol septal ablation and albumin-glutaraldehyde (BioGlue) for septal ablation to percutaneously treat the patient's LVOT obstruction, followed by use of an Amplatzer vascular plug for percutaneous closure of an antero-medial mitral PVL associated with severe regurgitation. Percutaneous interventional management of these entities may be considered as an initial therapeutic option, especially in high-risk patients with significant morbidity and mortality of repeat surgical operations.

Health care systems are increasing efforts to minimize postoperative hospital stays to improve resource use. Common explanations for extended postoperative stay are baseline patient sickness, postoperative complications, or physician practice differences. However, the degree to which extended length of stay (LOS) represents patient illness or postoperative complications remains unknown. The aim is to investigate the influence of postoperative complications and elderly patient comorbidities on extended LOS after anterior cervical discectomy and fusion. This retrospective study was performed from January 1, 2008, to December 31, 2014, on data from the American College of Surgeons National Surgical Quality Improvement Program. Patient demographics, comorbidities, LOS, and inpatient complications were recorded. Multivariable logistic regression analysis was used to determine the odds ratio for risk-adjusted extended LOS. The primary outcome was the degree extended LOS represented patient illness or postoperative complications. Of 4730 participants, 1351 (28.56%) had extended LOS. A minority of patients with extended LOS had a history of relevant comorbidities-diabetes (29.53%), chronic obstructive pulmonary disease (9.4%), congestive heart failure (1.04%), myocardial infarction (0.33%), acute renal failure (0.3%), and stroke (5.92%). Among patients with normal LOS, 96.8% had no complications, 2.7% had 1 complication, and 0.5% had greater than 1 complication. In patients with extended LOS, 79.4% had no complications, 14.5% had 1 complication, and 6.1% had greater than 1 complication (P < 0.0001). Our study suggests much of LOS variation after an anterior cervical discectomy and fusion is not attributable to baseline patient illness or complications and most likely represents differences in practice style or surgeon preference.

Twenty-eight patients underwent surgery for intractable pain, duodenal or extrahepatic biliary obstruction secondary to chronic pancreatitis. Eleven had pancreatic duct obstruction alone, six biliary obstruction alone, seven combined pancreatic and biliary, two combined biliary and duodenal, one combined pancreatic and duodenal, and one simultaneous pancreatic, biliary, and duodenal obstruction. Pancreatitis was secondary to alcohol in all but one case. The following operations were performed: longitudinal pancreatojejunostomy (20), choledochoduodenostomy (8), choledochojejunostomy (7), cholecystojejunostomy (1), and gastrojejunostomy (4). Of the 20 patients with pancreatic duct drainage, pain relief was complete in 11 and partial in six. Initial incomplete relief of pain, or recurrence, stimulated further diagnostic procedures, leading to improvement or correction of the problem in five patients. A significant (p less than 0.01) fall in alkaline phosphatase (935 +/- 228 to 219 +/- 61 U/L) occurred following surgery. One patient was subsequently found to have pancreatic carcinoma. Two patients were lost to follow-up and four patients died (one perioperative and three late). In conclusion, the possibility of pancreatic, biliary, and duodenal obstruction must be considered in symptomatic patients with chronic pancreatitis. Surgery must be individualized. Drainage procedures, either alone or in combination, are associated with a low morbidity and improved clinical condition and may be preferable to resection in the surgical management of these patients.

Strongyloidiasis hyperinfection and disseminated disease have high mortality rates due to several complications and early detection of Strongyloides infection is therefore prudent. A 37-year-old male patient came with chronic diarrhea, intractable vomiting and was found to have hyponatremia, and anemia on the initial laboratory tests. Further work up revealed syndrome of inappropriate antidiuretic secretion to be the cause of the hyponatremia in addition to gastrointestinal loses. His hospital course was complicated by persistent hyponatremia and later development of partial small bowel obstruction. Considering his symptoms we had a suspicion of small bowel pathology for which he underwent an esophagogastroduodenoscopywith biopsies that revealed strongyloidosis as the cause of his symptoms. He was also found to have human T-cell lymphotropic virus infection, likely contributing to the disseminated disease. He was started on ivermectin with complete resolution of symptoms and improvement of hyponatremia. It is very important to suspect Strongyloides infection in a patient presenting with syndrome ofinappropriate antidiuretic secretion as hyperinfection and disseminated disease can be life threatening without antihelmintic therapy.

2016-01-01

The surgical management of patients with malignant biliary and duodenal obstruction is complex. Tumor excision is no longer possible in the majority of patients with malignant obstructive jaundice and duodenal obstruction. The aim of the present study was to evaluate the effectiveness of intraluminal dual stent placement in malignant biliary and duodenal obstruction. In total, 20 patients with malignant obstructive jaundice and duodenal obstruction, including 6 with pancreatic carcinoma, 11 with cholangiocarcinoma, 1 with duodenal carcinoma and 2 with abdominal lymph node metastasis, were treated with intraluminal stent placement. Bile duct obstruction with late occurrence of duodenal obstruction was observed in 16 cases, and duodenal obstruction followed by a late occurrence of bile duct obstruction was observed in 3 cases, while, in 1 case, bile duct obstruction and duodenal obstruction occurred simultaneously. After X-ray fluoroscopy revealed obstruction in the bile duct and duodenum, stents were placed into the respective lumens. Percutaneous transhepatic placement was employed for the biliary stent, while the duodenal stent was placed perioraly. The clinical outcomes, including complications associated with the procedures and patency of the stents, were evaluated. The biliary and duodenal stents were successfully implanted in 18 patients and the technical success rate was 90% (18/20). A total of 39 stents were implanted in 20 patients. In 2 cases, duodenal stent placement failed following biliary stent placement. Duodenal obstruction remitted in 15 patients, and 1 patient succumbed to aspiration pneumonia 5 days after the procedure. No severe complications were observed in any other patient. The survival time of the 18 patients was 5–21 months (median, 9.6 months), and 6 of those patients survived for >12 months. The present study suggests that X-ray fluoroscopy-guided intraluminal stent implantation is an effective procedure for the treatment of malignant biliary and duodenal obstruction. PMID:26889267

PurposeDifferent techniques have been described for stenting of venous obstructions. We report our experience with two different confluence stenting techniques to treat chronic bi-iliocaval obstructions.Materials and MethodsBetween 11/2009 and 08/2014 we treated 40 patients for chronic total bi-iliocaval obstructions. Pre-operative magnetic resonance venography showed bilateral extensive post-thrombotic scarring in common and external iliac veins as well as obstruction of the inferior vena cava (IVC). Stenting of the IVC was performed with large self-expandable stents down to the level of the iliocaval confluence. To bridge the confluence, either self-expandable stents were placed inside the IVC stent (24 patients, SECS group) ormore » high radial force balloon-expandable stents were placed at the same level (16 patients, BECS group). In both cases, bilateral iliac extensions were performed using nitinol stents.ResultsRecanalization was achieved for all patients. In 15 (38 %) patients, a hybrid procedure with endophlebectomy and arteriovenous fistula creation needed to be performed because of significant involvement of inflow vessels below the inguinal ligament. Mean follow-up was 443 ± 438 days (range 7–1683 days). For all patients, primary, assisted-primary, and secondary patency rate at 36 months were 70, 73, and 78 %, respectively. Twelve-month patency rates in the SECS group were 85, 85, and 95 % for primary, assisted-primary, and secondary patency. In the BECS group, primary patency was 100 % during a mean follow-up period of 134 ± 118 (range 29–337) days.ConclusionStenting of chronic bi-iliocaval obstruction shows relatively high patency rates at medium follow-up. Short-term patency seems to favor confluence stenting with balloon-expandable stents.« less

Chronic pancreatitis is defined as a pathological fibro-inflammatory syndrome of the pancreas in individuals with genetic, environmental and/or other risk factors who develop persistent pathological responses to parenchymal injury or stress. Potential causes can include toxic factors (such as alcohol or smoking), metabolic abnormalities, idiopathic mechanisms, genetics, autoimmune responses and obstructive mechanisms. The pathophysiology of chronic pancreatitis is fairly complex and includes acinar cell injury, acinar stress responses, duct dysfunction, persistent or altered inflammation, and/or neuro-immune crosstalk, but these mechanisms are not completely understood. Chronic pancreatitis is characterized by ongoing inflammation of the pancreas that results in progressive loss of the endocrine and exocrine compartment owing to atrophy and/or replacement with fibrotic tissue. Functional consequences include recurrent or constant abdominal pain, diabetes mellitus (endocrine insufficiency) and maldigestion (exocrine insufficiency). Diagnosing early-stage chronic pancreatitis is challenging as changes are subtle, ill-defined and overlap those of other disorders. Later stages are characterized by variable fibrosis and calcification of the pancreatic parenchyma; dilatation, distortion and stricturing of the pancreatic ducts; pseudocysts; intrapancreatic bile duct stricturing; narrowing of the duodenum; and superior mesenteric, portal and/or splenic vein thrombosis. Treatment options comprise medical, radiological, endoscopic and surgical interventions, but evidence-based approaches are limited. This Primer highlights the major progress that has been made in understanding the pathophysiology, presentation, prevalence and management of chronic pancreatitis and its complications.

When conventional ERCP methods fail because of periampullary or ductal obstruction, EUS-guided cholangiopancreatography (EUS-CP) may aid in pancreaticobiliary access. To report our experience when using single-operator EUS-CP. An academic tertiary-referral center. Consecutive patients undergoing EUS-CP were prospectively identified. These patients had undergone failed attempt(s) at therapeutic ERCP. A data sheet was used to record indications, reasons for failed ERCP, EUS-CP visualization of the duct of interest, transpapillary or transenteric intervention, clinical follow-up, and complications. Technical success was decompression of the duct of interest. Clinical success was resolution of jaundice or a > or = 50% reduction in pain or narcotics, as applicable. Between February 2003 and June 2007, EUS-CP was attempted in 20 patients (11 men, 9 women; mean [SD] age 58 +/- 14.9 years). Indications included jaundice (n = 8), biliary stones (n = 3), chronic pancreatitis (n = 6), acute pancreatitis (n = 2), and papillary stenosis (n = 1). Reasons for failed ERCP included periampullary mass (n = 8), intradiverticular papillae (n = 4), and pancreatic duct (PD) stricture (n = 7) or stone (n = 1). Technical success was achieved in 18 of 20 patients (90%). Biliary decompression was obtained in 11 of 12 patients (92%) (7 transpapillary and 4 transenteric-transcholedochal). Pancreatic decompression was obtained in 7 of 8 patients (88%) (3 transpapillary, 4 transgastric). On follow-up, clinical improvement was noted in 15 of 20 patients (70%). For treatment of pain associated with chronic pancreatitis, pain scores decreased by a mean of 1.75 (P = .18). Complications (in 2 of 20 [10%]) included perforation (n = 1) and respiratory failure (n = 1). A single-center nonrandomized observational study with a small patient population. At our academic referral center, single-operator EUS-CP provided decompression of obstructed ducts and may be performed after a failed attempt at conventional ERCP during the same endoscopic session.

Cigarette smoking is a major public health problem, which leads to the formation of chronic obstructive pulmonary disease (COPD) and is one of the main causes of avoidable death and disability worldwide. The aim of study was analysis and comparison of the visceral fat in the body of the three groups of subjects (non-smokers, smokers and COPD patients) by Tanita Viscan 140. The control group was composed of: (1) non-smokers (n=30), consisted of 13 males (43.4%) and 17 women (56.6%) - the average age was 52 ± 6.51 years and (2) smokers (n=30), consisted of 12 men (40%) and 18 women (60%) - the average age 46.53 ± 9.22 years. Study group consisted of patients with COPD (n=60), which consisted of 48 men (80%) and 12 women (20%). Mean age was 69.25 ± 9.90 years. The measurement of visceral fat by Tanita Viscan device 140, which uses bioelectrical impedance analysis to measure fat in the abdomen of the patient in the supine position. High levels of visceral fat (women from 36.9% to 52.3% and more, men from 27.1% to 40.3% or more) were observed in 19 patients (3 women and 16 men), with 19 smokers (10 women and 9 men) and non-smokers in 22 subjects (10 women and 12 men). The average value of waist circumference measured with a Tanita Viscan 140 was in the group of patients 96.38 ± 12.27 cm, in the group of smokers 95.23 ± 10.12 cm and in group of non-smokers 96.86 ± 10.88 cm. The results of our work are of great importance for the health assessment not only among patients with COPD but also in the group of smokers. Therefore it would be appropriate to remind the general public, eg. by campaign for chronic obstructive pulmonary disease and its serious complications and reduce the life quality of these patients and thus help protect human health and in particular young people from the harmful effects of tobacco products.

Streptococcus pneumoniae is a rare pathogen of sepsis in patients with antithyroid drug-induced agranulocytosis. We herein describe a case of antithyroid drug-induced agranulocytosis complicated by pneumococcal sepsis and upper airway obstruction. A 27-year-old woman who was previously prescribed methimazole for nine months presented with a four-day history of a sore throat. She nearly choked and was diagnosed with febrile agranulocytosis. She was successfully treated with intubation, intravenous antibiotics and granulocyte colony-stimulating factor. Her blood cultures yielded S. pneumoniae. Emergency airway management, treatment of sepsis and the administration of granulocyte colony-stimulating factor can improve the clinical course of antithyroid drug-induced pneumococcal sepsis in patients with airway obstruction.

Lipodystrophy is a common complication of highly active antiretroviral therapy and is associated with significant comorbidities. Altered fat distribution, particularly lipohypertrophy of the dorsal cervical fat pad is associated with reduced quality of life as well as medical complications. We report the rare case of a patient with airway obstruction secondary to HIV-associated lipodystrophy. Ultrasound-assisted liposuction was successfully performed to relieve her airway obstruction and to facilitate a tracheostomy. To the best of our knowledge, this is the first documented case of its kind. We also provide a brief review of the literature on the current management options for HIV-associated lipodystrophy.

To describe changes in cognitive function, as measured by the trail making test; to identify distinct patterns of change in cognitive function; and to examine predictors of change in cognitive function in people with severe chronic obstructive pulmonary disease. How cognitive function changes in people with chronic obstructive pulmonary disease and what factors influence those changes over time is not well known, despite the fact that it declines rapidly in this population and significantly impacts functional decline in healthy older adults. A secondary analysis and longitudinal study with a follow-up period of 3 years. A data set from the National Emphysema Treatment Trial provided participant data. Patients with severe chronic obstructive pulmonary disease (n = 307) were recruited at a clinical site. Several demographic and clinical measures were assessed at baseline. Trail making test scores were measured at baseline, 1, 2 and 3 years. Cognitive function was stable for 3 years in people with chronic obstructive pulmonary disease. However, four distinct patterns of change in cognitive function were identified. Age, education, 6-min walk distance and cognitive impairment scores at baseline on the trail making test Part B were significant predictors of worsening cognitive function and below-average cognitive function over 3 years. These findings suggest that increasing exercise capacity improves cognitive function and delays deterioration of cognitive function in people with COPD. Understanding the trajectories of change in cognitive function and predictors of change in cognitive function over 3 years may enable health care providers to identify patients at greatest risk of developing mental deterioration and those who might benefit from interventions to improve cognitive function. Health care providers should periodically assess and frequently screen people with COPD for cognitive function. © 2018 John Wiley & Sons Ltd.

Objective Osteoporosis, which is now recognized as a major comorbidity of chronic obstructive pulmonary disease (COPD), must be diagnosed by appropriate methods. The aims of this study were to clarify the relationships between bone mineral density (BMD) and COPD-related clinical variables and to explore the association of BMD with the updated Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification in men. Methods We enrolled 50 Japanese men with clinically stable COPD who underwent dual-energy X-ray absorptiometry (DEXA), pulmonary function testing, and computerized tomography (CT) and who had completed a questionnaire (COPD assessment test [CAT]). We determined the association between the T-score and other tested parameters and compared the BMD of patients in each GOLD category. Results Twenty-three of the 50 patients (46.0%) were diagnosed with osteopenia, and 7 (14.0%) were diagnosed with osteoporosis. The BMD findings were significantly correlated with the CAT score, forced expiratory volume in 1 second percentage predicted (FEV 1 % predicted), low attenuation volume percentage (LAV%), and percentage of cross-sectional area of small pulmonary vessels (%CSA) on CT images. Notably, the median T-score of the GOLD category D participants was significantly lower than that of the participants in each of the other categories (A [-0.98], B [-1.06], C [-1.05], and D [-2.19], p<0.05). Conclusion Reduced BMD was associated with airflow limitation, extent of radiographic findings, and a poor quality of life (QOL) in patients with COPD. The BMD of GOLD category D patients was the lowest of all of the patients evaluated, and category D patients may benefit from active intervention for osteoporosis.

Management of a postbulbar duodenal ulcer and stricture causing gastric outlet obstruction: A case report.

PubMed

Mirande, Maxwell D; Mirande, Raul A

2018-05-01

Peptic ulcer disease has significantly decreased over the past several decades making the need for definitive surgical intervention an infrequent occurrence. A 44-year-old Caucasian female was sent to the emergency department by her primary care physician for right upper quadrant abdominal pain which had been intermittent for the past two months but acutely worsened over the last five days. During this time, she was unable to tolerate oral intake with intractable nausea and vomiting. Upper GI endoscopy revealed a tight stricture in the second part of the duodenum and antral biopsy was Helicobacter pylori negative. Patient underwent two rounds of balloon dilation with short lived symptomatic relief. An open pylorus-preserving duodenal stricturoplasty using a Heineke-Mikulicz technique was then performed. The operation was successful and the patient has had no reoccurrence of her symptoms. Gastric outlet obstruction is an uncommon complication of peptic ulcer disease in respect to chronic nonsteroidal anti-inflammatory drug use. The unique location of the patient's stricture and her desire to minimize post-operative GI alterations demanded a review of surgical options and identified the benefits of maintaining the patient's original anatomy versus choosing an extra-anatomic approach. This case presented a unique challenge and demonstrated the need for definitive surgical interventions in the treatment of peptic ulcer induced gastric outlet obstruction. This case adds support for the direct anatomic treatment of duodenal strictures when conservative measures fail and perhaps promotes further development of laparoscopic management of gastric outlet obstruction in the future.

Magnetic therapy is ineffective for the treatment of snoring and obstructive sleep apnea syndrome.

Dexter, D

Snoring and the obstructive sleep apnea syndrome are common and chronic ailments with potentially serious medical complications. There are several accepted treatments, but these can be uncomfortable, inconvenient, and expensive. A number of alternative treatments have been reported to be beneficial in the treatment of obstructive sleep apnea and snoring. They are advertised in magazines, on the radio and television, and on the Internet. The lay press is reporting about the effectiveness of these treatments without the benefit of clinical trials or scientific studies. Among the therapies currently being promoted for the treatment of snoring and sleep apnea is biomagnetic therapy. Unlike many of the other treatments which have not undergone scientific evaluation, biomagnetic therapy has been evaluated in the past. In fact, the evaluation of biomagnetic therapy is one of the first controlled scientific investigations found in the literature. This report showed that magnet therapy had no medicinal value. Despite this clear evidence, magnetic therapy continues to be utilized today and currently is being promoted for the treatment of snoring and sleep apnea. At out Sleep Disorder Center, we have had the opportunity to evaluate a patient with severe obstructive sleep apnea both before and after treatment with magnetic therapy, as well as with conventional therapy. Our study clearly indicates there was no benefit from magnetic therapy in this case. While alternative therapy may be helpful in the treatment of certain medical conditions, extreme care must be exercised to prevent inappropriate treatment or undertreat-ment of significant medical problems. Close clinical follow-up and controlled studies are important in determining the effectiveness of therapies.

2015-01-01

Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease state characterized by persistent airflow limitation that is usually progressive and associated with an enhanced chronic inflammatory process. It is increasingly recognized as a major public health problem, affecting more than 20 million adults in the US. It is also recognized as a leading cause of hospitalizations and is the fourth leading cause of death in the US. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) operates to promote evidence-based management of COPD, increase awareness and encourage research. In 2011, GOLD published a consensus report detailing evidence-based management strategies for COPD, which were last updated in 2015. In recent years, newer strategies and a growing number of new pharmacologic agents to treat symptoms of COPD have also been introduced and show promise in improving the management of COPD. We aim to provide an evidence-based review of the available and upcoming pharmacologic and non-pharmacologic treatment options for stable COPD, with continued emphasis on evidence-based management.

Post-laparotomy wound dehiscence, evantration and evisceration are important complications leading to an increase in both morbidity and mortality. Incisional hernias are frequently observed following abdominal surgeries and their occurrence is related to various local and systemic factors. This study aims to analyze the factors affecting wound healing by investigating the parameters that may cause wound dehiscence, incisional hernia, sinus formation and chronic incisional pain. The records of 265 patients who underwent major abdominal surgery were analyzed. The data on patient characteristics, medication, surgical procedure type, type of suture and surgical instruments used and complications were recorded. The patients were followed up with respect to sinus formation, incisional hernia occurrence and presence of chronic incision pain. Statistical analysis was performed using SPSS 10.00 program. The groups were compared via chi-square tests. Significance was determined as p<0.05. Multi-variate analysis was done by forward logistic regression analysis. 115 (43.4%) patients were female and 150 (56.6%) were male. Ninety-four (35.5%) patients were under 50 years old and 171 (64.5%) were older than 50 years. The median follow-up period was 28 months (0-48). Factors affecting wound dehiscence were found to be; creation of an ostomy (p=0.002), postoperative pulmonary problems (p=0.001) and wound infection (p=0.001). Factors leading to incisional hernia were; incision type (p=0.002), formation of an ostomy (p=0.002), postoperative bowel obstruction (p=0.027), postoperative pulmonary problems (p=0.017) and wound infection (p=0.011). Awareness of the factors causing wound dehiscence and incisional hernia in abdominal surgery, means of intervention to the risk factors and taking relevant measures may prevent complications. Surgical complications that occur in the postoperative period are especially related to wound healing problems.

Exercise adherence in patients with chronic obstructive pulmonary disease: an exploration of motivation and goals.

Adherence to an exercise regimen is challenging. Motivation is an important factor that can enhance exercise adherence. A key component of motivation is the setting and accomplishment of specified goals. Therefore, it is important to understand the relationship between patients' motivation and goals. Motivation and goal orientation in 14 participants with chronic obstructive pulmonary disease were assessed. Participants were also interviewed to explore their exercise and activity goals. Motivation was significantly associated with goal orientation. In addition, participants reported many explicit activity goals, but few participants had set specific exercise goals. The inconsistency between activity and exercise goals has not been reported previously. Findings from this preliminary study provide novel and relevant information that may help care providers understand factors that may influence exercise adherence in people with chronic obstructive pulmonary disease.

We present an unusual and rare complication caused by gastric band erosion into the stomach after band placement 15 years ago. The complication was only picked up after the band had subsequently migrated from the stomach at the site of erosion, to the distal ileum causing acute small bowel obstruction and focal perforation requiring emergency laparotomy. Abdominal pain in patients with gastric band should always be treated as serious until proven otherwise. PMID:28500263

In Yugoslavia the diseases of the respiratory system (without tuberculosis) ranges with 23% in front of all other organ-localised diseases. 53--95% of all chronic non-specific lung diseases are registrated in the chest clinics of the different republics. 67% of all lung diseases registrated belong to the obstructive syndrom, 6% are bronchial carcinomas and 27% represent the group of other chronic pulmonary diseases. 31,5% of all patients with chronic obstructive bronchitis are younger than 50 years old, 34,7% are in the age-group between 50-65 years. Assuming the best registered incidence and prevalence rates of bronchial carcinoma, chronic bronchitis, asthma and emphysema in Slowenia as a basis, the expected morbidity of these diseases in each autonomic republic are compared.

INTRODUCTION Meckel's diverticulum is a rare congenital abnormality arising due to the persistence of the vitelline duct in 1–3% of the population. Clinical presentation is varied and includes rectal bleeding, intestinal obstruction, diverticulitis and ulceration; therefore diagnosis can be difficult. PRESENTATION OF CASE We report a case of acute appendicitis complicated by persistent post operative small bowel obstruction. Further surgical examination of the bowel revealed an non-inflamed, inverted Meckel's diverticulum causing intussusception. DISCUSSION Intestinal obstruction in patients with Meckel's diverticulum may be caused by volvulus, intussusception or incarceration of the diverticulum into a hernia. Obstruction secondary to intussusception is relatively uncommon and frequently leads to a confusing and complicated clinical picture. CONCLUSION Consideration of Meckel's diverticulum although a rare diagnosis is imperative and this case raises the question “should surgeons routinely examine the bowel for Meckel's diverticulum at laparoscopy?” PMID:22288035

The case of post TB is a problem that arises in the community. Pulmonary tuberculosis (TB) can affect lung function. Therefore, we evaluated impaired pulmonary function in subjects with diagnosed prior pulmonary TB. A Case Series study, pulmonary function test was performed in subjects with a history of pulmonary tuberculosis; aged ≥18 years were included. Exclusion criteria was a subject who had asthma, obesity, abnormal thorax and smoking history. We measured FEV1 and FVC to evaluate pulmonary function. Airflow obstruction was FEV1/FVC%<75 and restriction was FVC<80% according to Indonesia’s pneumomobile project. This study was obtained from 23 patients with post pulmonary TB, 5 subjects (23%) had airflow obstruction with FEV1/FVC% value <75%, 15 subjects (71.4%) had abnormalities restriction with FVC value <80% and 3 subjects (5.6%) had normal lung function. Obstructive lung disease is one of the complications of impaired lung function in post pulmonary TB.

Hepatic CT findings were analyzed in 44 patients with autosomal-dominant polycystic kidney disease and were correlated with liver and renal function tests and liver, splenic, and renal CT volume measurements. CT showed many large liver cysts in 31.8% of patients, small liver cysts in 25%, and no liver cysts in 43.2%. Patients with many large cysts often showed increased liver volumes. There was no correlation between severity of liver involvement and extent of renal cystic disease as determined from urea nitrogen and creatinine levels and renal volumes. Liver function tests were normal except in two patients, one with a cholangiocarcinoma,more » which may have arisen from a cyst, and the other with an infected liver cyst and chronic active hepatitis. Accordingly, if liver function tests are abnormal, an attempt should be made to identify complications of polycystic liver disease such as tumor cyst infection, and biliary obstruction. CT is a useful method for detecting liver cysts and identifying patients at risk for these complications.« less

Endoscopic orbital decompression (EnOD) has proven to be safe and effective for the treatment of Graves' orbitopathy; however, complications do occur. Although the literature focuses on orbital complications, sinonasal complications including postobstructive sinusitis, hemorrhage, and cerebrospinal fluid (CSF) leak can also be challenging to manage. This study examines the incidence and management of sinonasal complications in these patients. Retrospective review. Clinical data, surgical findings, and postoperative outcomes were reviewed of patients who underwent EnOD for Graves' disease between March 2004 and November 2010. The incidence and management of postoperative sinonasal complications requiring an intervention were examined. The study group consisted of 50 consecutive patients (86 decompression procedures): 11 males and 39 females with an average age of 48.6 years (SD = 12.9). Incidence of significant sinonasal complications was 3.5% (5/86): with one patient experiencing postoperative hemorrhage requiring operative management, three patients with postoperative obstructive sinusitis, and one patient with nasal obstruction secondary to nasal adhesions that required lysis. The maxillary sinus was the most commonly involved and was managed using the mega-antrostomy technique. In the case of frontal sinusitis, an endoscopic transaxillary approach was utilized to avoid injury to decompressed orbital contents. All complications were successfully managed without sequelae. Sinonasal complications following EnOD are uncommon. In the setting of a decompressed orbit, even routine types of postoperative issues can be challenging and require additional considerations. Successful management of postoperative sinusitis related to outflow obstruction may require more extensive approaches and novel techniques.

Extrahepatic portal vein obstruction (EHPVO) is a primary vascular condition characterized by chronic long standing blockage and cavernous transformation of portal vein with or without additional involvement of intrahepatic branches, splenic or superior mesenteric vein. Patients generally present in childhood with multiple episodes of variceal bleed and EHPVO is the predominant cause of paediatric portal hypertension (PHT) in developing countries. It is a pre-hepatic type of PHT in which liver functions and morphology are preserved till late. Characteristic imaging findings include multiple parabiliary venous collaterals which form to bypass the obstructed portal vein with resultant changes in biliary tree termed portal biliopathy or portal cavernoma cholangiopathy. Ultrasound with Doppler, computed tomography, magnetic resonance cholangiography and magnetic resonance portovenography are non-invasive techniques which can provide a comprehensive analysis of degree and extent of EHPVO, collaterals and bile duct abnormalities. These can also be used to assess in surgical planning as well screening for shunt patency in post-operative patients. The multitude of changes and complications seen in EHPVO can be addressed by various radiological interventional procedures. The myriad of symptoms arising secondary to vascular, biliary, visceral and neurocognitive changes in EHPVO can be managed by various radiological interventions like transjugular intra-hepatic portosystemic shunt, percutaneous transhepatic biliary drainage, partial splenic embolization, balloon occluded retrograde obliteration of portosystemic shunt (PSS) and revision of PSS.

One of the most significant problems in the treatment of elderly patients is incorrect use of inhaler devices. The purpose of the present study was to assess the parameters affecting treatment adherence among elderly patients. Spirometry, the Mini-Mental State Examination for cognitive impairment and the Morisky Medication Adherence Scale-4 were carried out in 121 (88 chronic obstructive lung disease patients according to the Global Initiative for Chronic Obstructive Lung Disease, 33 asthma patients according to The Global Initiative for Asthma (GINA) criteria) participants aged over 65 years. The patients with cognitive impairment, low socioeconomic status, a high number of admissions to an emergency service in past year and the presence of dyspnea or sputum had significantly lower inhalation device use scores (P = 0.017, 0.03, 0.025, 0.03 and 0.02). The patients with high Mini-Mental State Examination scores and forced expiratory volume in 1 s (as liter and percentage) were found to be more successful in using inhaler devices (P = 0.005, 0.007 and 0.022). There was a negative correlation between number of hospitalizations and inhalation device score (P = 0.021).The participants without education/training by a doctor about the inhaler device had a significantly poorer treatment adherence (P < 0.001). Older chronic obstructive lung disease and asthmatic patients have more difficulty with the correct use of inhaler devices. Cognitive impairment might be an important parameter that can affect inhalation device technique. Socioeconomic status, smoking, pulmonary symptoms and admissions to hospital were also thought to have effects on the adherence to inhalation therapy. The type of chronic respiratory disease (chronic obstructive lung disease/asthma) is not a major factor influencing therapy adherence. Assessment of cognitive functions, choosing suitable inhalation devices and educational programs for inhaler use could improve the success of inhaler technique in elderly patients.

Kapella, Mary C; Vispute, Sachin; Zhu, Bingqian; Herdegen, James J

2017-09-01

Actigraphy is commonly used to measure sleep outcomes so that sleep can be measured conveniently at home over multiple nights. Actigraphy has been validated in people with sleep disturbances; however, the validity of scoring settings in people with chronic medical illnesses such as chronic obstructive pulmonary disease remains unclear. The purpose of this secondary analysis was to compare actigraphy-customized scoring settings with polysomnography (PSG) for the measurement of sleep outcomes in people with chronic obstructive pulmonary disease who have insomnia. Participants underwent overnight sleep assessment simultaneously by PSG and actigraphy at the University of Illinois of Chicago Sleep Science Center. Fifty participants (35 men and 15 women) with mild-to-severe chronic obstructive pulmonary disease and co-existing insomnia were included in the analysis. Sleep onset latency, total sleep time (TST), wake after sleep onset (WASO), and sleep efficiency (SE) were calculated independently from data derived from PSG and actigraphy. Actigraphy sleep outcome scores obtained at the default setting and several customized actigraphy settings were compared to the scored PSG results. Although no single setting was optimal for all sleep outcomes, the combination of 10 consecutive immobile minutes for sleep onset or end and an activity threshold of 10 worked well. Actigraphy overestimated TST and SE and underestimated WASO, but there was no difference in variance between PSG and actigraphy in TST and SE when the 10 × 10 combination was used. As the average TST and SE increased, the agreement between PSG and actigraphy appeared to increase, and as the average WASO decreased, the agreement between PSG and actigraphy appeared to increase. Results support the conclusion that the default actigraphy settings may not be optimal for people with chronic obstructive pulmonary disease and co-existing insomnia. Copyright © 2017 The Author(s).

Recently, comorbidities such as impaired cognitive function have been attracting more focus when considering the management of chronic obstructive pulmonary disease (COPD). Here we investigated the relationship between cognitive function and the categories given in the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines in 2011. Specifically, after controlling for non-COPD covariates, we assessed the clinical features that may be predictive of cognitive impairment in patients with COPD. We recruited 119 stable patients with mild to very severe COPD. We administered a broad array of standardized neuropsychological tests that assessed cognitive functions in the domains of attention, memory, psychomotor coordination and language. Cognitive scores were significantly different between patients falling within GOLD 2011 categories. Scores were lower in patients with high future risk compared with low future risk. In parallel, there were significant differences in cognitive function between COPD patient subgroups when patients were grouped according to the forced expiratory volume in 1 s, exacerbation history and C-reactive protein levels. After controlling for non-COPD predictors, only exacerbation history remained a significant predictor of cognitive scores. The number of exacerbation events in a year may be used as a predictor of cognitive impairment in patients with COPD. © 2014 Asian Pacific Society of Respirology.

Objectives To determine the importance of fear and anxiety at the time of an exacerbation of chronic obstructive pulmonary disease. To assess the influence of carers and health professionals on this fear and anxiety. Design A qualitative study to elicit the views of patients and their carers during a hospital admission for exacerbations of chronic obstructive pulmonary disease. Setting Interviews were conducted in a District General Hospital. Participants Twenty patients were interviewed shortly after admission to hospital with an exacerbation. Main outcome measures Key themes were identified using cross-sectional thematic analysis of transcripts where commonalities and differences were identified. Results Four themes emerged: panic and fear; anxiety management techniques used during an exacerbation; intervention from family members and carers; response to medical services. Conclusion Panic and fear are important emotions prior to admission. Many patients recognised the link between panic-fear and a worsening of symptoms, and some were able to use self-management techniques to reduce their panic-fear. Some relatives were seen as helping and others exacerbating the symptoms of panic-fear. The emergency services were seen as positive: providing reassurance and a sense of safety. How best to help patients with chronic obstructive pulmonary disease manage panic and fear remains a challenge. PMID:26664734

In 91 patients with chronic obstructive lung disease (COLD), the severity of this disease according to the Classifications of the European Respiratory Society (ERS) and the Global Initiative on Chronic Obstructive Lung Disease (GOLD) was compared with that of pulmonary dysfunction according to the data of a comprehensive study, involving the determination of bronchial patency, lung volumes, capacities, and gas-exchange function. This follows that the ERS and GOLD classifications are to be positively appraised as they provide an eligible group of patients for clinical practice in terms of the severity of pulmonary dysfunction and that of COLD. However, the concomitant clinical use of both classifications cannot be regarded as justifiable due to that there are differences in the number of detectable grades (stages) of COLD and borderline (COLD differentiating grades (stages) values of EFV1). In this connection, both classifications have approximately equally significant merits and shortcomings and it is practically impossible to give preference to one of them as the best one. The optimal way out of the established situation is to develop a new (improved) classification of the severity of COLD on the bases of these two existing classifications.

This review discusses the recent Asian chronic obstructive lung disease (COPD) studies that characterize stable COPD, to understand its peculiarities. Asian research has improved our understanding of COPD. Household air pollution (HAP) is as important as smoking. Smoking in Asia is varied, and noncigarette smoking exposure remains under-investigated. Prevalence studies are often questionnaire based. Spirometry-based prevalence needs study. Burden of obstructive lung disease studies are getting published. Female COPD in Asia is predominantly HAP induced. The patients are underweight, milder 'Global Initiative for Obstructive Lung Disease- class' and have compromised health-related quality of life often with depression and anxiety, but other comorbidities do occur and are getting defined.Nonsmokers' COPD is often associated with small airway thickening, less emphysema, but considerable morbidity. Asian COPD may have an eosinophilic component, but its significance is unknown. There is genetic predisposition among some Asians to COPD, and among some patients to lung cancer. The emerging pandemic of lifestyle diseases demands that metabolic and cardiovascular comorbidities in COPD need investigation. COPD in Asia is increasing and burdensome. It is affecting both sexes; is caused by HAP as much as smoking; causes poor quality of life and intense psychological burden; and is associated with unique patho-physiology, which will require research and action.

Obstructive sleep apnea (OSA) and sleep-disordered breathing (SDB) can result in impaired cognition and mental acuity, and the generation of mood disorders, including depression. However, the mechanisms of neuronal damage for these complications have not been elucidated. Accordingly, using immunohistochemical technique with monoclonal antibody against single-stranded DNA, we examined the morphological effects of chronic recurrent apnea on neurons in the hippocampus and related forebrain sites in guinea pigs. Our results show that a large number of neurons labeled by anti-ssDNA antibody were present in the cingulate, insular and frontal cortices, the hippocampus and the amygdala in conjunction with periods of recurrent apnea. However, no labeling was observed in comparable regions of the brain in control guinea pigs. In the cortices of experimental animals, labeled neurons were detected mainly in the superficial layers (II-III) in the frontal, insular and cingulate cortex. In the hippocampus, most labeled neurons were located in the CA1 region, in which most of stained neurons were observed in strata pyramidal, while only a few positive neurons were located in the strata radiatum and the strata oriens. In addition, a large number of labeled neurons were also detected in the central nucleus of amygdala in the guinea pigs underwent recurrent periods of apnea. The present data indicate that recurrent apnea results in cell death in the hippocampus and related forebrain regions via mechanisms of apoptosis, which may represent the basis for the clinical complications of obstructive sleep apnea and sleep-disordered breathing.

Summary Background We performed this observational prospective study to evaluate the results of the application of a diagnostic and therapeutic algorithm for complicated parapneumonic pleural effusion (CPPE) and pleural parapneumonic empyema (PPE). Material/Methods From 2001 to 2007, 210 patients with CPPE and PPE were confirmed through thoracocentesis and treated with pleural drainage tubes (PD), fibrinolytic treatment or surgical intervention (videothoracoscopy and posterolateral thoracotomy). Patients were divided into 3 groups: I (PD); II (PD and fibrinolytic treatment); IIIa (surgery after PD and fibrinolysis), and IIIb (direct surgery). The statistical study was done by variance analysis (ANOVA), χ 2 and Fisher exact test. Results The presence of alcohol or drug consumption, smoking and chronic obstructive pulmonary disease (COPD) were strongly associated with a great necessity for surgical treatment. The IIIa group was associated with increased drainage time, length of stay and complications. No mortality was observed. The selective use of PD and intrapleural fibrinolysis makes surgery unnecessary in more than 75% of cases. Conclusions The selective use of PD and fibrinolysis avoids surgery in more than 75% of cases. However, patients who require surgery have more complications, longer hospital stay, and more days on PD and they are more likely to require admittance to the Intensive Care Unit. PMID:22739734

Endoscopic stenting with a self-expandable metallic stent (SEMS) is a widely accepted procedure for malignant colonic obstruction. The Colonic Stent Safe Procedure Research Group conducted the present prospective feasibility study. Our objectives were to estimate the safety and feasibility of SEMS placement as a bridge to surgery (BTS) for malignant colorectal obstruction. We conducted a prospective, observational, single-arm, multicenter clinical trial from March 2012 to October 2013. Each patient was treated with an uncovered WallFlex enteral colonic stent. Patients were followed up until discharge after surgery. A total of 518 consecutive patients were enrolled in this study. The cohort intended for BTS consisted of 312 patients (61 %), and the stent could be released in 305 patients. Technical and clinical success rates were 98 and 92 %, respectively. Elective surgery was performed in 297 patients, and emergency surgery was performed in eight patients for the treatment of complications. The overall preoperative complication rate was 7.2 %. Major complications, including perforation, occurred in 1.6 %, persistent colonic obstruction occurred in 1.0 %, and stent migration occurred in 1.3 % patients. The median time from SEMS to surgery was 16 days. Silent perforations were observed in 1.3 %. Open and laparoscopic surgery was performed in 121 and 184 patients, respectively. The tumor could be resected in 297 patients. The primary anastomosis rate was 92 %. The rate of anastomotic leakage was 4 %, and the overall stoma creation rate was 10 %. The median duration of hospitalization following surgery was 12 days. Overall postoperative morbidity and mortality rates were 16 and 0.7 %, respectively. This largest, multicenter, prospective study demonstrates the feasibility of SEMS placement as a BTS for malignant colorectal obstruction. SEMS serves as a safe and effective BTS with acceptable stoma creation and complication rates in patients with acute malignant colonic obstruction.

Independently, obstructive sleep apnea (OSA) and infectious mononucleosis are not uncommon in the pediatric population, but acute onset of OSA, as a respiratory complication in the setting of acute EBV infection is extremely uncommon. Previous reports of this clinical entity are sparse and from nearly two decades ago. Urgent adenotonsillectomy was commonly advocated. This complication may be managed medically with systemic corticosteroids and non-invasive continuous positive airway pressure (CPAP), and a case is presented to highlight an updated management approach to this rarely encountered clinical problem in children.

Upper gastrointestinal (GI) stents are increasingly being used to manage upper GI obstructions. Initially developed for palliative treatment of esophageal cancer, upper GI stents now play an emerging role in benign strictures of the upper GI tract. Because recurrent obstruction and stent-related complications are common, new modifications of stents have been implemented. Self-expandable metal stents (SEMS) have replaced older plastic stents. In addition, newly designed SEMS have been developed to prevent complications. This review provides an overview of the various types, indications, methods, complications, and clinical outcomes of upper GI stents in a number of malignant and benign disorders dividing the esophagus and gastroduodenum.

We conducted a randomized trial to compare endoscopic and surgical drainage of the pancreatic duct. All symptomatic patients with chronic pancreatitis and a distal obstruction of the pancreatic duct but without an inflammatory mass were eligible for the study. We randomly assigned patients to undergo endoscopic transampullary drainage of the pancreatic duct or operative pancreaticojejunostomy. The primary end point was the average Izbicki pain score during 2 years of follow-up. The secondary end points were pain relief at the end of follow-up, physical and mental health, morbidity, mortality, length of hospital stay, number of procedures undergone, and changes in pancreatic function. Thirty-nine patients underwent randomization: 19 to endoscopic treatment (16 of whom underwent lithotripsy) and 20 to operative pancreaticojejunostomy. During the 24 months of follow-up, patients who underwent surgery, as compared with those who were treated endoscopically, had lower Izbicki pain scores (25 vs. 51, P<0.001) and better physical health summary scores on the Medical Outcomes Study 36-Item Short-Form General Health Survey questionnaire (P=0.003). At the end of follow-up, complete or partial pain relief was achieved in 32% of patients assigned to endoscopic drainage as compared with 75% of patients assigned to surgical drainage (P=0.007). Rates of complications, length of hospital stay, and changes in pancreatic function were similar in the two treatment groups, but patients receiving endoscopic treatment required more procedures than did patients in the surgery group (a median of eight vs. three, P<0.001). Surgical drainage of the pancreatic duct was more effective than endoscopic treatment in patients with obstruction of the pancreatic duct due to chronic pancreatitis.

Background: Adaptive servoventilation (ASV) can be effective therapy for specific types of central apnea such as Cheyne-Stokes respiration (CSR). Patients treated chronically with opioids develop central apneas and ataxic breathing patterns (Biot's respiration), but therapy with CPAP is usually unsuccessful. There are no published studies of ASV in patients with sleep apnea complicated by chronic opioid therapy. Methods: Retrospective analysis of 22 consecutive patients referred for evaluation and treatment of sleep apnea who had been using opioid medications for at least 6 months, had an apnea-hypopnea index (AHI) >20/h, and had been tested with ASV. Baseline polysomnography was compared with CPAP and ASV. Outcome variables: AHI, central apnea index (CAI), obstructive apnea index (OAI), hypopnea index (HI), desaturation index, mean SpO2, lowest SpO2, time SpO2 <90%, and degree of Biot's respiration. Results: Mean (SD) AHI measured 66.6/h (37.3) at baseline, 70.1/h (32.6) on CPAP, and 54.2/h (33.0) on ASV. With ASV, the mean OAI was significantly decreased to 2.4/h (p < 0.0001), and the mean HI increased significantly to 35.7/h (p < 0.0001). The decrease of CAI from 26.4/h to 15.6/h was not significant (p = 0.127). Biot's breathing persisted, and oxygenation parameters were unimproved with ASV. Conclusions: Due to residual respiratory events and hypoxemia, ASV was considered insufficient therapy in these patients. Persistence of obstructive events could be due to suboptimal pressure settings (end expiratory and/or maximal inspiratory). Residual central events could be related to fundamental differences in the pathophysiology of CSR compared to opioid induced breathing disturbances.

C-reactive protein as a predictor of disease in smokers and former smokers: a review

PubMed Central

Tonstad, S; Cowan, J L

2009-01-01

Background: Cigarette smoking is a classical and a major risk factor in the development of several diseases with an inflammatory component, including cardiovascular disease and chronic obstructive pulmonary disease. Improvements in assays for protein markers of inflammation have led to many studies on these factors and their roles in disease. Aims: C-reactive protein (CRP) is one such marker and this review focuses on the evidence for using CRP as a diagnostic marker and how levels of this protein are modified according to the smoking status of the patient, both in terms of the current amount of cigarettes smoked and how CRP levels change following smoking cessation. Conclusions: Assay of CRP levels may be useful in monitoring disease progression and determining risk of future cardiovascular complications. However, as this marker is also an indicator of acute inflammation and challenges to the immune system, some caution must be exercised in interpreting the available data on CRP levels in patients with different chronic comorbidities.

Conservation of pancreatic tissue by combined gastric, biliary, and pancreatic duct drainage for pain from chronic pancreatitis.

Warshaw, A L

In patients with chronic pancreatitis, the sclerosing process of the pancreas may constrict not only the pancreatic duct for also the bile duct and duodenum. This study analyzes the prevalence of these obstructive lesions in 58 consecutive patients with chronic pancreatitis requiring surgery for either pain (57 patients) or for painless jaundice (1 patient). There was significant biliary obstruction in 21, 4 of whom also had symptomatic duodenal obstruction. All 21 patients with biliary and duodenal obstruction were among the 38 with a dilated pancreatic duct suitable for pancreaticojejunostomy (modified Puestow procedure). None of the 20 patients with small duct pancreatitis had biliary or duodenal obstruction. Pseudocysts were distributed evenly between the two groups (9 of 38 patients with a dilated duct versus 4 of 20 patients with small duct pancreatitis). Pancreaticojejunostomy combined with choledochoenterostomy and gastrojejunostomy in appropriately selected patients provided good to excellent long-term (mean 3.6 years) relief of pain in 30 of 36 patients (83 percent). There was no correlation between successful relief of pain and development of pancreatic exocrine or endocrine insufficiency or calcification. Stenosis of the bile duct developed some years subsequent to pancreaticojejunostomy in four patients and required a second operation for choledochoenterostomy in three. Three other patients required secondary pancreatic resections due to failure of the pancreaticojejunostomy to relieve pain. It is often possible to effect excellent relief of symptoms with maximal conservation of remaining pancreatic functions despite sclerotic obstruction of multiple organ systems.

We describe a 24-year-old man with a cystic hygroma of the left side of the lower neck that led to sudden death. Cystic hygroma (cystic lymphangioma) is a congenital malformation of the lymphatic system. The patient, who had a tracheostomy because of airway obstruction from the cystic hygroma, was found dead with his tracheostomy tube on the floor next to him. Complications of cystic hygroma include infiltration of the neck causing airway obstruction, dysphagia, pain, and obstructive sleep apnea.

Upper airway obstruction is an uncommon but recognized complication of infectious mononucleosis. The management depends upon the degree of airway compromise. In the case described, severe airway obstruction was treated by securing the airway with awake fibre-optic endoscopic intubation and then proceeding to tonsillectomy. Bilateral inferiorly loculated quinsies were encountered unexpectedly and drained. This is the first report of 'bilateral' quinsies, associated with infectious mononucleosis and severe airway obstruction. The association, pathogenesis and significance of this finding are also discussed.

Elongated uvula is relatively an uncommon condition. Upper airway obstruction is often a missed complication of such a rare condition. Clinical presentations of upper airway obstruction often mimic asthma. Hence it is very easily mis-diagnosed as asthma. Spirometry offers a very simple test to diagnose upper airway obstruction very early and easily. Once diagnosed, the management of elongated uvula, almost exclusively, is surgical excision leading to total cure. Here is a case report of such a rare condition. PMID:20539769

Compared to emergency surgery, self-expandable metallic stents are effective and safe when used as bridge-to-surgery (BTS) in operable patients with acute colorectal cancer obstruction. In this study, we report data on the new conformable colonic stents. To evaluate clinical effectiveness of conformable stents as BTS in patients with acute colorectal cancer obstruction. This was a retrospective study. The study was conducted at six Italian Endoscopic Units. Data about patients with acute malignant colorectal obstruction were collected between 2007 and 2012. All patients were treated with conformable stents as BTS. Technical success, clinical success, rate of primary anastomosis and colostomy, early and late complications were evaluated. Data about 88 patients (62 males) were reviewed in this study. Conformable SEMS were correctly deployed in 86 out of 88 patients, with resolution of obstruction in all treated patients. Tumor resection with primary anastomosis was possible in all patients. A temporary colostomy was performed in 40. Early complications did not occur. Late complications occurred in 11 patients. Stent migration was significantly higher in patients treated with partially-covered stents compared to the uncovered group (35% vs. 0%, P<0.001). Endoscopical re-intervention was required in 12% of patients. One patient with rectal cancer had an anastomotic dehiscence after surgery and he was successfully treated with endoscopic clipping. One year after surgery, all patients were alive and local recurrence have not been documented. This was a retrospective and uncontrolled study. Preliminary data from this large case series are encouraging, with a high rate of technical and clinical success and low rate of clinically relevant complications. Partially-covered SEMS should be avoided in order to reduce the risk of endoscopic re-intervention. Copyright © 2016. Published by Elsevier Masson SAS.

Surgery is the treatment of choice for symptomatic tracheal obstruction due to benign or malignant thyroid disease. In case of inoperability, or when surgery is refused, few therapeutic alternatives are available. Interventional bronchoscopic procedures have only been reported anecdotally. The objective of this study is to evaluate the results of interventional bronchoscopic procedures in the treatment of severe tracheal obstruction due to thyroid disease. Retrospective cohort analysis. University hospital, tertiary referral center. Thirty consecutive patients referred for bronchoscopic treatment of benign (n = 17) or malignant (n = 13) thyroid-related upper airway obstruction due to tracheomalacia, extrinsic compression, and/or tracheal ingrowth. Indications for bronchoscopic treatment were medical or surgical inoperability, prevention or treatment of tracheomalacia, and refusal of surgery. There were no procedure-related complications. Rigid bronchoscopy with dilatation, stenting and/or Nd-YAG laser treatment, and clinical follow-up. Subjective improvement, pulmonary function tests, early and late complications, and survival. In the benign group, immediate (100% relief of dyspnea) and long-term (88% relief of dyspnea) results were excellent after airway stenting (21 stents used in 17 patients). There was one unrelated death 1 week after stenting in a 98-year-old patient. There were 6% and 30% short-term and long-term complications, respectively, that could be managed endoscopically. In the malignant group, Nd-YAG laser treatment (n = 3) and stenting (n = 13) yielded immediate and long-term success in 92% of patients. There were 15% short-term and 8% long-term complications. Median survival time was 540 days. Interventional bronchoscopic procedures including Nd-YAG laser treatment and stenting are valuable alternatives to surgery in inoperable thyroid-induced tracheal obstruction, or when surgery is refused.

Biliary stricture in chronic pancreatitis (CP) is not uncommon. Previously, all cases were managed by surgery. Nowadays, three important modes of treatment in these patients are observation, endoscopic therapy, and surgery. In the modern era, surgery is recommended only in a subset of patients who develop biliary symptoms or those who have asymptomatic biliary stricture and require surgery for intractable abdominal pain. We want to report on our experience regarding surgical management of CP-induced benign biliary stricture. Over a period of 5 years, we have managed 340 cases of CP at our institution. Bile duct stricture was found in 62 patients. But, surgical intervention was required in 44 patients, and the remaining 18 patients were managed conservatively. Demographic data, operative procedures, postoperative complications, and follow-up parameters of these patients were collected from our prospective database. A total 44 patients were operated for biliary obstruction in the background of CP. Three patients were excluded, so the final analysis was based on 41 patients. The indication for surgery was symptomatic biliary stricture in 27 patients and asymptomatic biliary stricture with intractable abdominal pain in 14 patients. The most commonly performed operation was Frey's procedure. There was no inhospital mortality. Thirty-five patients were well at a mean follow-up of 24.4 months (range 3 to 54 months). Surgery is still the best option for CP-induced benign biliary stricture, and Frey's procedure is a versatile operation unless you suspect malignancy as the cause of biliary obstruction.

Is endoscopic therapy the treatment of choice in all patients with chronic pancreatitis?

PubMed

Jabłońska, Beata

Chronic pancreatitis (CP) is a progressive inflammatory disease of the pancreas characterized by destruction of the pancreatic parenchyma with subsequent fibrosis that leads to pancreatic exocrine and endocrine insufficiency. Abdominal pain and local complications (bile duct or duodenal stenosis and pancreatic tumor) secondary to CP are indications for therapy. At the beginning, medical therapy is used. More invasive treatment is recommended for patients with pancreatic duct stones (PDS) and pancreatic obstruction in whom standard medical therapy is not sufficient. Recently, Clarke et al assessed the long-term effectiveness of endoscopic therapy (ET) in CP patients. The authors compared ET with medical treatment. They reported that ET was clinically successful in 50% of patients with symptomatic CP. In this commentary, current CP treatment, including indications for ET and surgery in CP patients, is discussed. Recommendations for endoscopic treatment of CP according to the European Society of Gastrointestinal Endoscopy Clinical Guidelines are reviewed. Different surgical methods used in the treatment of CP patients are also discussed. ET is the most useful in patients with large PDS, pancreatic duct obstruction and dilation. It should be the first-line option because it is less invasive than surgery. Surgery should be the first-line option in patients in whom ET has failed or in those with a pancreatic mass with suspicion of malignancy. ET is a very effective and less invasive procedure, but it cannot be recommended as the treatment of choice in all CP patients.

Resting energy expenditure and carbohydrate oxidation are higher in elderly patients with COPD: a case control study

PubMed Central

2012-01-01

Background Elderly patients with chronic obstructive pulmonary disease (COPD) usually have a compromised nutritional status which is an independent predictor of morbidity and mortality. To know the Resting Energy Expenditure (REE) and the substrate oxidation measurement is essential to prevent these complications. This study aimed to compare the REE, respiratory quotient (RQ) and body composition between patients with and without COPD. Methods This case–control study assessed 20 patients with chronic obstructive pulmonary disease attending a pulmonary rehabilitation program. The group of subjects without COPD (control group) consisted of 20 elderly patients attending a university gym, patients of a private service and a public healthy care. Consumption of oxygen (O2) and carbon dioxide (CO2) was determined by indirect calorimetry and used for calculating the resting energy expenditure and respiratory quotient. Body mass index (BMI) and waist circumference (WC) were also measured. Percentage of body fat (%BF), lean mass (kg) and muscle mass (kg) were determined by bioimpedance. The fat free mass index (FFMI) and muscle mass index (MMI) were then calculated. Results The COPD group had lower BMI than control (p = 0.02). However, WC, % BF, FFMI and MM-I did not differ between the groups. The COPD group had greater RQ (p = 0.01), REE (p = 0.009) and carbohydrate oxidation (p = 0.002). Conclusions Elderly patients with COPD had higher REE, RQ and carbohydrate oxidation than controls. PMID:22672689

Pannus formation is an infrequent but serious complication of prosthetic heart valve surgery. The cause of pannus is recognized as a bioreaction to the prostheses; histological investigations have shown that pannus comprises collagen and elastic tissues containing endothelial cells, chronic inflammatory cells, and myofibroblasts. However, the detailed mechanism of its formation has not been fully demonstrated. We aimed to evaluate the potential role of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-2 (MMP-2) in the pathogenesis of pannus formation in three patients with mechanical prosthetic heart valves. Pannus specimens removed from the prostheses were fixed in 10% neutral-buffered formalin for 24 hours after surgical removal and paraffin-embedded using standard procedures. Serial sections were cut at 4 µm for immunohistochemistry analysis. Hematoxylin and eosin (HE) was used in the histological analysis. VEGF and MMP-2 were studied in the immunohistochemistry analysis. Three patients with mechanical prosthetic obstruction due to pannus overgrowth underwent redo valve surgery. In the first and second patients, the mitral prosthesis was explanted along with the pannus overgrowth. The third patient had both aortic and mitral prostheses; the aortic prosthesis was explanted with obstructive pannus formation, whereas the mitral valve was spared with excision of the nonobstructive pannus. The immunohistochemical study demonstrated the expressions of MMP-2 and VEGF in all of the pannus specimens acquired from these cases. VEGF and MMP-2 may play a role in the mechanism of pannus formation as the elements of the chronic active inflammatory process.

Pharmacological treatment of chronic obstructive pulmonary disease (COPD) relies principally on long-acting bronchodilators. Inhaled corticosteroids (ICS) were introduced for COPD two decades ago, despite the fact that no randomized trial had yet assessed their efficacy for this indication. Since then, the numerous randomized trials and meta-analyses performed to justify their use in COPD have been contradictory and controversial. Moreover, observational studies have reported efficacy rates so exceptional that they are almost too good to be true. These studies contain important methodological flaws that produce the appearance of efficacy. The randomized trials infringe the fundamental principle of intention-to-treat analysis, an analysis necessary to prevent important biases. Two other complications are the interruption of treatment at the moment of randomization and the use of a run-in period; in both cases, the withdrawal of treatment can introduce bias. The observational studies reporting phenomenal reductions in mortality with ICS were distorted by "immortal time" bias. Finally, recent data suggest that the effect of ICS/bronchodilator combinations is due mainly to the effect of the long-acting bronchodilator. Given the absence of proof of the efficacy of inhaled corticosteroids in COPD and their associated risks, especially of ocular damage and pneumonia, and particularly among the elderly, as well as the high doses currently prescribed in COPD, it is difficult to recommend their use in this indication. They should be prescribed in COPD for at most a limited population of patients.

Past research demonstrates a possible association between herbicide exposure and respiratory health. Biologic plausibility and inhalation as a mode of exposure further support the contention that herbicides may act as adverse contributors to respiratory status, especially in military personnel who were responsible for chemical maintenance and distribution during the Vietnam War. This study examines the association between chronic obstructive pulmonary disease and herbicide exposure among Vietnam-era U.S. Army Chemical Corps veterans. A 2013 three-phase health study was conducted that included a survey (mail or telephone), in-home physical examinations, and medical record reviews/abstractions. Living, eligible veterans (n = 4,027) were identified using an existing cohort of men (n = 5,609) who either served in Vietnam (n = 2,872) or never served in Southeast Asia (n = 2,737). The health survey collected self-reported data on physician-diagnosed pulmonary conditions (chronic obstructive pulmonary disease, emphysema, and chronic bronchitis), service-related herbicide spraying history, cigarette smoking status, alcohol use, and demographics. Data from service personnel files confirmed chemical operations involvement and service status, whereas serum samples analyzed for 2,3,7,8-tetrachlorodibenzo-p-dioxin supported self-reported herbicide exposure. National Institute for Occupational Safety and Health quality-assured spirometry was performed during the physical examinations on a subset of survey respondents (n = 468 of 733 selected for participation and who provided consent) to determine mainly spirometric obstructive respiratory disease (forced expiratory volume in 1 second [FEV 1 ]/forced vital capacity [FVC] < lower limit of normal [LLN], FVC ≥ LLN, and FEV 1  < LLN; and FEV 1 /FVC < LLN and FEV 1  ≥ LLN). Associations between chronic obstructive pulmonary disease and veteran characteristics were examined (n = 403) using multivariable models. Reporting here specifically on spirometrically diagnosed disease, prevalence of obstructive disease was 8.4%. No significant differences in mean values of FEV 1 /FVC or mean percentage of predicted for FEV 1 and FVC between herbicide sprayers and nonsprayers were found. The odds of spirometric obstructive disease among sprayers were 0.65 times the odds among nonsprayers (adjusted odds ratio, 0.65; 95% confidence interval, 0.28-1.47), although elevated odds for spirometric restrictive disease were observed for sprayers versus nonsprayers (adjusted odds ratio, 1.61; 95% confidence interval, 0.85-3.06). Race/ethnicity, anthropometric measures, and cigarette smoking status accounted for differences among veterans' respiratory patterns. No significant association between herbicide exposure and spirometry-determined chronic obstructive pulmonary disease was found. Greater focus is required on confirming diagnoses of respiratory disease through spirometry in epidemiological research.

Transtracheal oxygen and positive airway pressure: A salvage technique in overlap syndrome.

PubMed

Biscardi, Frank Hugo; Rubio, Edmundo Raul

2014-01-01

The coexistence of sleep apnea-hypopnea syndrome (SAHS) with chronic obstructive pulmonary disease (COPD) occurs commonly. This so called overlap syndrome leads to more profound hypoxemia, hypercapnic respiratory failure, and pulmonary hypertension than each of these conditions independently. Not infrequently, these patients show profound hypoxemia, despite optimal continuous positive airway pressure (CPAP) therapy for their SAHS. We report a case where CPAP therapy with additional in-line oxygen supplementation failed to accomplish adequate oxygenation. Adding transtracheal oxygen therapy (TTOT) to CPAP therapy provided better results. We review the literature on transtracheal oxygen therapy and how this technique may play a significant role in these complicated patients with overlap syndrome, obviating the need for more invasive procedures, such as tracheostomy.

Jaundice is a yellowish pigmentation of skin and mucous membranes caused by hyperbilirubinemia, which itself has various causes. Jaundice related to malignant tumors is classified as obstructive jaundice. This disease proceeds from biliary tract obstruction and liver failure by progression of intrahepatic tumors, including metastases from other malignancies. Biliary tract cancer, pancreatic head cancer, or lymph nodes metastases from other sites of cancer are mainly responsible for the obstruction of the bile duct. In patients with obstructive jaundice, biliary drainage is often required in order to give treatments such as chemotherapy. In patients with biliary drainage, various complications arise, such as cholangitis due to obstruction ofa biliary stent, and bleeding from the ulcer due to a dislodged stent to the duodenum. It is crucial to manage those complications as oncologic emergencies. Jaundice of liver failure due to hepatic metastases is often observed in patients with gastrointestinal malignancies such as gastric cancer or colorectal cancer. Although chemotherapy is the usual application for those patients, useful anti-cancer agents are limited. It is crucial to diagnose and decide the best treatments as soon as possible for patients with very advanced hepatic metastases.

Non-invasive ventilation (NIV) is recognized as first line therapy in acute hypercapnic respiratory failure and chronic alveolar hypoventilation caused by several diseases (restrictive thoracic disorders, neuromuscular disease and obesity-hypoventilation syndrome). In Switzerland and other European countries, long-term NIV has also been applied in hypercapnic patients with chronic obstructive pulmonary disease (COPD). However, only recently has conclusive evidence showing benefits of long-term NIV become available. Long-term NIV in COPD has now shown its efficacy in many studies. However, despite these findings, indications, ventilatory settings and monitoring remain poorly known and topic of debate.

Application of phase-diverse phase retrieval to wavefront sensing in non-connected complicated pupil optics

Mao, Heng; Wang, Xiao; Zhao, Dazun

2007-07-01

Baseline algorithm, as a tool in wavefront sensing (WFS), incorporates the phase-diverse phase retrieval (PDPR) method with hybrid-unwrapping approach to ensure a unique pupil phase estimate with high WFS accuracy even in the case of high dynamic range aberration, as long as the pupil shape is of a convex set. However, for a complicated pupil, such as that in obstructed pupil optics, the said unwrapping approach would fail owing to the fake values at points located in obstructed areas of the pupil. Thus a modified unwrapping approach that can minimize the negative effects of the obstructed areas is proposed. Simulations have shown the validity of this unwrapping approach when it is embedded in Baseline algorithm.

Gastric bezoars are concretions of undigested material, and Coca-Cola therapy is an easy, efficacious and safe approach for bezoar treatment. Gastric outlet obstruction due to a migratory gastric bezoar during Coca-Cola therapy is an uncommon presentation and, to the best of our knowledge, no cases have been previously reported. We herein describe one such case with no known predisposing factors that recovered via the endoscopic technique. A thorough literature search was performed, which yielded eight relevant patients from seven publications, all of who developed gastrointestinal obstruction during dissolution treatment and recovered uneventfully after surgical intervention. In conclusion, this potential complication should be kept in mind in the event that alternative treatment is necessary.

This article is concerned with the modern concepts of chronic obstructive pulmonary disease. Also, it presents the international definition of "pulmonary rehabilitation". Especially much attention is given to the physical rehabilitation as one of the main and fundamental components of medical rehabilitation of the patients presenting with chronic obstructive pulmonary disease. The up-to-date approaches to the application of fitness gymnastics for the purpose of scientific research and clinical practice are considered with special reference to the combination of cyclic, static, and dynamic loads with the use of relevant modern equipment. The data on the effectiveness and safety of these rehabilitative technologies are discussed in the context of their application for further research in the field of rehabilitative medicine. Recommendations are proposed on the implementation of these methods in the current practical work.

To study a clinical effect of fenspirid and its impact on external respiration function in patients with chronic obstructive bronchitis (COB) in the exacerbation phase. 30 COB patients participated in the trial (20 males, 10 females, age 39-80 years). The severity of clinical symptoms (cough, sputum, dyspnea) was studied using special scales. External respiration function was examined by a spirometric system "Tamrac system spiro sense Y2 14". Fenspirid treatment was conducted in a dose 80 mg twice a day for 3 months. Control examinations were made 2 weeks, 1 and 3 months after the treatment start. A 3-month treatment with fenspirid resulted in regression of COB symptoms: cough and sputum ceased, dyspnea decreased. This led to improvement in external respiration function, especially in patients with mixed ventilatory disorders with prevailing restriction. Fenspirid is an effective and well tolerated treatment of chronic obstructive bronchitis.

Nutrition in chronic pancreatitis.

The pancreas is a major player in nutrient digestion. In chronic pancreatitis both exocrine and endocrine insufficiency may develop leading to malnutrition over time. Maldigestion is often a late complication of chronic pancreatic and depends on the severity of the underlying disease. The severity of malnutrition is correlated with two major factors: (1) malabsorption and depletion of nutrients (e.g., alcoholism and pain) causes impaired nutritional status; and (2) increased metabolic activity due to the severity of the disease. Nutritional deficiencies negatively affect outcome if they are not treated. Nutritional assessment and the clinical severity of the disease are important for planning any nutritional intervention. Good nutritional practice includes screening to identify patients at risk, followed by a thoroughly nutritional assessment and nutrition plan for risk patients. Treatment should be multidisciplinary and the mainstay of treatment is abstinence from alcohol, pain treatment, dietary modifications and pancreatic enzyme supplementation. To achieve energy-end protein requirements, oral supplementation might be beneficial. Enteral nutrition may be used when patients do not have sufficient calorie intake as in pylero-duodenal-stenosis, inflammation or prior to surgery and can be necessary if weight loss continues. Parenteral nutrition is very seldom used in patients with chronic pancreatitis and should only be used in case of GI-tract obstruction or as a supplement to enteral nutrition.

Alcohol-induced chronic pancreatitis in rats after temporary occlusion of biliopancreatic ducts with Ethibloc.

PubMed

Pap, A; Boros, L

Chronic obstructive pancreatitis-like histological and biochemical alterations were provoked in male Wistar rats with Ethibloc occlusion of the common bile duct and the main pancreatic ducts. After the disappearance of the glue from the ducts, a gradual and almost total recovery was demonstrated during a 2-month observation period. About 12 g/kg of alcohol (20% vol/vol) given daily by gastric intubation and ad libitum intake inhibited the recovery of pancreatic weight and enzyme contents in the occluded rats, and within a 2-month period chronic calcifying-type pancreatitis became evident with some signs of remaining obstructive pancreatitis-like lesions. Cessation of alcohol administration after 2 months resulted in a recovery of pancreatic weight and enzyme contents, although morphological regeneration was less pronounced and calcification remained visible in some rats. A 50% raw soy flour diet provoked some further changes in the proportion of enzymes without any supplementary increases of pancreatic weight and protein content. This animal model of chronic pancreatitis demonstrates that chronic obstructive and calcifying pancreatitis can appear together and earlier if the etiological factors act in combination. Suppression of pancreatic regeneration by alcohol seems to be necessary to maintain chronic pancreatitis-like lesions and to develop calcification.

Of the patients with chronic obstructive pulmonary disease (COLD) and severe obstructive syndrome, 39 whose age was under 40 were selected. In 23 of them, the anamnesis revealed bronchopulmonary affections in childhood, that required admission into the hospital (19 were non-smokers). Of the rest of 16 patients, 14 were hard smokers that started to smoke before the age of 14. The functional picture was severely modified, similarly to that of the COLD patients in the 6th decade of life. This suggests that the degradation process started in the childhood, and that the chronic respiratory diseases and/or smoking at an early age had an important role.

An 85-year-old, never-smoking man presented with exertional dyspnea. He had been exposed to silica dust in the work place. Chest computed tomography revealed bronchial wall thickening without emphysema. A pulmonary function test showed airflow obstruction without impaired gas transfer. Airway hyperresponsiveness and reversibility were not evident. A transbronchial lung biopsy showed findings suggestive of mineral dust exposure, such as fibrosis and slight pigmentation of bronchioles. He was diagnosed with non-smoking chronic obstructive pulmonary disease (COPD) due to occupational exposure to silica dust. His symptoms were improved using an inhaled long-acting bronchodilator. The clinical characteristics of non-smoking COPD are discussed in this report.

Medical comorbidities have been shown to cause an increase in peri-and postoperative complications following total knee arthroplasty (TKA). However, the increase in cost associated with these complications has yet to be determined. Factors that influence cost have been of great interest particularly after the initiation of bundled payment initiatives. In this study, we present and quantify the influence of common medical comorbidities on the cost of care in patients undergoing primary TKA. A retrospective level of evidence III study was performed using the PearlDiver supercomputer to identify patients who underwent primary TKA between 2007 and 2015. Patients were stratified by medical comorbidities and compared using analysis of variance for reimbursements for the day of surgery and over 90 days postoperatively. A cohort of 137,073 US patients was identified as having undergone primary TKA between 2007 and 2015. The mean entire episode-of-care reimbursement was $23,701 (range: $21,294-26,299; standard deviation [SD] $2,611). The highest reimbursements were seen in patients with chronic obstructive pulmonary disease (mean $26,299; SD $3,030), hepatitis C (mean $25,662; SD $2,766), morbid obesity (mean $25,450; SD $2,154), chronic kidney disease (mean $25,131, $3,361), and cirrhosis (mean $24,890; SD $2,547). Medical comorbidities significantly impact reimbursements, and therefore cost, after primary TKA. Comprehensive preoperative optimization for patients with medical comorbidities undergoing TKA is highly recommended and may reduce perioperative complications, improve patient outcome, and ultimately reduce cost.

Pulmonary distribution of an inhaled radioaerosol was analyzed in 20 cases of chronic obstructive pulmonary disease (COPD) and 8 of other OPD. Nonciliary/ciliary partition of the distribution correlated with the severity of airway obstruction and approximated 3 : 1 in mild and 1 : 3 in very severe obstruction. In nuclear images, the distribution featured contrast abnormalities of hyperdeposition and hypodeposition. Intense hyperdeposition most commonly occurred in hilar and perihilar large airways. In isolated instances, hyperdeposition almost certainly occurred focally at sites of partial bronchial obstruction and diffusely by expiratory trapping; hypodeposition occurred distally to bronchial obstruction and in areasmore » of parenchymal loss.

Objective: To investigate the problems encountered in the application of the standard (hereinafter referred to as standard) for the diagnosis of chronic obstructive pulmonary disease caused by occu-pational irritant chemicals, to provide reference for the revision of the new standard, to reduce the number of missed patients in occupational COPD, and to get rid of the working environment of those who suffer from chronic respiratory diseases due to long-term exposure to poisons., slowing the progression of the disease. Methods: Using Delphi (Delphi) Expert research method, after the senior experts to demonstrate, to under-stand the GBZ 237-2011 "occupational irritant chemicals to the diagnosis of chronic obstructive pulmonary dis-ease" standard evaluation of the system encountered problems, to seek expert advice, The problems encoun-tered during the clinical implementation of the standards promulgated in 2011 are presented. Results: Through the Delphi Expert investigation method, it is found that experts agree on the content evaluation and implemen-tation evaluation in the standard, but the operational evaluation of the standard is disputed. According to the clinical experience, the experts believe that the range of occupational irritant gases should be expanded, and the operation of the problem of smoking, seniority determination and occupational contact history should be challenged during the diagnosis. Conclusions: Since the promulgation in 2011 of the criteria for the diagnosis of chronic obstructive pulmonary disease caused by occupational stimulant chemicals, there have been some problems in the implementation process, which have caused many occupationally exposed to irritating gases to suffer from "occupational chronic respiratory Diseases" without a definitive diagnosis.

Evaluation of plasma, erythrocytes, and bronchoalveolar lavage fluid antioxidant defense system in sulfur mustard-injured patients.

Sulfur mustard (SM) is a strong alkylating agent that causes acute and chronic effects on different organs following exposure. Main late respiratory complications are chronic obstructive pulmonary disease, bronchiectasis, asthma, and bronchiolitis obliterans. It seems that oxidative stress plays a major role in pathogenesis of diseases. This study was undertaken to evaluate the long-term effect of SM on plasma, erythrocytes, and brochoalveolar lavage fluid antioxidant defense system in SM-injured patients. Brochoalveolar lavage fluid, plasma, and erythrocyte samples were taken from 54 patients in the case group exposed to SM and 25 controls with chronic respiratory disease without a history of exposure to SM. Superoxide dismutase, catalase, and glutathione peroxidase activities in lavage fluid, plasma, and erythrocytes were significantly higher in case group. The increased glutathione S-transferase activity in lavage fluid was associated with a depletion of glutathione and an increase of malondialdehyde levels. There was no significant change observed in glutathione reductase activity. The data suggest that oxidative damage might have an important role for patients exposed to SM. SM may induce an oxidative stress response by depleting the antioxidant defense systems and increasing lipid peroxidation in lung cells.

An in vitro analysis of the effect of acidosis on coagulation in chronic disease states - a thromboelastograph study.

Thrombosis is a complication of many chronic illnesses. Chronic obstructive pulmonary disease (COPD) and diabetes mellitus are common medical conditions frequently associated with a hypercoagulable state. Acidaemia has been shown to reduce coagulation. COPD and diabetes mellitus during acute deterioration can present with a severe acidaemia. The impact of this acidaemia on coagulation is poorly studied. Patients presenting with a diagnosis of diabetic ketoacidosis or type II respiratory failure from COPD and a pH of less than 7.2 were included in our study. A coagulation screen and a thromboelastograph (TEG) were performed on admission and 24 hours later. The mean pH on admission was 7.07 and mean base excess was -16.3. The activated partial thromboplastin time was associated with pH change but remained within the normal range (26-41 s). All other coagulation and TEG parameters failed to show evidence of association (p>0.05). In the two models of non-haemorrhagic acidosis investigated, coagulation was not altered by the changes in pH. More work is needed to understand the complex relationship between factors affecting coagulation in individual disease processes. © 2016 Royal College of Physicians.

The aim of this study was to assess the treatment patterns and 3-12-month complication rates associated with receiving prostate cryotherapy in a population-based study. Men >65 years diagnosed with incident localized prostate cancer in Surveillance Epidemiology End Results (SEER)-Medicare-linked database from 2004 to 2005 were identified. A total of 21,344 men were included in the study, of which 380 were treated initially with cryotherapy. Recipients of cryotherapy versus aggressive forms of prostate therapy (ie, radical prostatectomy or radiation therapy) were more likely to be older, have one co-morbidity, low income, live in the South and be diagnosed with indolent cancer. Complication rates increased from 3 to 12 months following cryotherapy. By the twelfth month, the rates for urinary incontinence, lower urinary tract obstruction, erectile dysfunction and bowel bleeding reached 9.8, 28.7, 20.1 and 3.3%, respectively. Diagnoses of hydronephrosis, urinary fistula or bowel fistula were not evident. The rates of corrective invasive procedures for lower urinary tract obstruction and erectile dysfunction were both <2.9% by the twelfth month. Overall, complications post-cryotherapy were modest; however, diagnoses for lower urinary tract obstruction and erectile dysfunction were common.

Role of the inflammasome in chronic obstructive pulmonary disease (COPD).

Inflammation is central to the development of chronic obstructive pulmonary disease (COPD), a pulmonary disorder characterized by chronic bronchitis, chronic airway obstruction, emphysema, associated to progressive and irreversible decline of lung function. Emerging genetic and pharmacological evidence suggests that IL-1-like cytokines are highly detected in the sputum and broncho-alveolar lavage (BAL) of COPD patients, implying the involvement of the multiprotein complex inflammasome. So far, scientific evidence has focused on nucleotide-binding oligomerization domain-like receptors protein 3 (NLRP3) inflammasome, a specialized inflammatory signaling platform that governs the maturation and secretion of IL-1-like cytokines through the regulation of caspase-1-dependent proteolytic processing. Some studies revealed that it is involved during airway inflammation typical of COPD. Based on the influence of cigarette smoke in various respiratory diseases, including COPD, in this view we report its effects in inflammatory and immune responses in COPD mouse models and in human subjects affected by COPD. In sharp contrast to what reported on experimental and clinical studies, randomized clinical trials show that indirect inflammasome inhibitors did not have any beneficial effect in moderate to severe COPD patients.

The aim of this study was to evaluate the effects of a traditional Chinese herbal medicine, dai-kenchu-to (DKT), on obstructive bowel diseases in children. We have treated 46 pediatric patients with various obstructive bowel diseases with DKT: six patients with postoperative ileus, 12 with large abdominal surgery (including three neonates), one with ano-rectal anomaly, three with Hirschsprung's disease, two with functional bowel obstructions, one with SMA syndrome, and 21 patients with chronic constipation. DKT (0.1-0.15 g/kg) was mixed with 5-10 ml of warm water, and was given orally two to three times a day. DKT was effective for 39 patients (85%) and their clinical symptoms improved. DKT was ineffective in seven patients: two with postoperative ileus, two with Hirschsprung's disease, and three with chronic constipation. DKT had mild but significant effects for various obstructive bowel diseases in children, while no side effects were encountered. Our current strategy for pediatric patients with obstructive bowel disease is to use DKT first and then test its efficacy. If DKT is effective, the regimen is continued. However, in cases where DKT is not effective, we will consider laparotomy or will further investigate the illness.

Objectives: To investigate whether air pollution is a potential risk factor for airways obstruction. Methods: A prospective cohort study (11.3±2.9 years) that took place in two areas (Eordea where concentration of PM10 was high and Grevena, Greece). We used the MRC questionnaire, spirometry, and anterior rhinomanometry at both visits. Results: Initially we examined 3046 subjects. After excluding chronic obstructive pulmonary disease (COPD) patients, we re-examined 872 subjects and 168 of them had developed COPD (Grevena: 24.3%, Eordea: 18.5%). Multivariable logistic regression analysis showed that the area of residence and thus exposure to air pollution was not a risk factor for the development of COPD (OR: 0.51, 95% CI: 0.18–1.46, P = 0.21). On the other hand, residence in Eordea was strongly related to the development of severe nasal obstruction (OR: 11.47, 95% CI: 6.15–21.40, P<0.001). Similar results were found after excluding patients with COPD stage I as well as in the subgroup of never smokers. Conclusion: Air pollution was associated with severe nasal obstruction but not with COPD development. PMID:24804336

Chronic obstructive pulmonary disease is the major growing cause of mortality and morbidity worldwide, and it is going to become the third most common cause of death by 2020. Chronic obstructive pulmonary disease is pathologically characterized by lung emphysema and small airway inflammation. Animal models are very important to get insights into the disease pathogenesis but current models of chronic obstructive pulmonary disease take a long time to develop. The need of a new model is compelling. In the present study we focus on the role of matrix metalloproteinases in the pathogenesis of chronic obstructive pulmonary disease and hypothesized that lung overexpression of latent matrix metalloproteinases-2 would allow the development of emphysema after short-term exposure to cigarette smoke extract inhalation. Human latent matrix metalloproteinases-2 transgenic mouse expressing high level of the protein in the lungs and wild type mouse were exposed to aerosolized cigarette smoke extract for two weeks. Transgenic mice showed significant lung emphysematous changes, increased infiltration of inflammatory cells and enhanced lung concentrations of inflammatory cytokines in the lungs compared to their wild type counterparts after inhalation of cigarette smoke extract. This novel mouse model will be a very useful tool for evaluating the mechanistic pathways and for development of novel therapies in cigarette smoke-associated lung emphysema.

The study included 10 Primary Care patients with advanced chronic obstructive pulmonary disease, their respective 10 caregivers, and 19 primary care professionals, as well as 2 lung specialists, 2 palliative care professionals involved in their care, and one clinical psychologist. Theoretical sampling. Semi-structured and in-depth interviews with patients, caregivers, and professionals (47 interviews). The emergent topics identified in patients and caregivers interviews refer to dyspnoea, the predominant symptom without effective treatment and with a major impact on patients and caregivers lives. A symptom with great functional, emotional and social repercussions to which they need to adapt in order to survive. Beyond pharmacological measures to control respiratory symptoms, proper care of patients with chronic obstructive pulmonary disease, requires understanding of suffering, the losses and limitations that it causes in their lives and those of their caregivers. A palliative, holistic and closer approach to their real experiences, together with an empowerment to adapt to debilitating symptoms, could contribute to a better life in the end-stages of the disease.

Whether unilateral or bilateral drainage should be performed for malignant hilar biliary obstruction remains a matter of debate. Although a Y-stent with a central wide-open mesh facilitates bilateral stent placement, it has its own limitations. This study aims to evaluate the feasibility and efficacy of a newly designed Y-configured bilateral self-expanding metallic stent (SEMS) for the treatment of hilar biliary obstruction. In this retrospective study, 14 consecutive patients with unresectable malignant hilar biliary obstruction (Bismuth type II or higher), who underwent placement of a newly designed Y-configured bilateral SEMS for hilar biliary obstruction from April 2013 to March 2015, were included into this study. Data on technical success, clinical success, stent patency, complications and patient survival were collected. Technical and clinical success was 100 and 92.9 %, respectively. Mean serum bilirubin level was significantly decreased 1 month after stent placement (P < 0.01). Furthermore, two patients (14.3 %) had early complications (one patient had severe hemobilia and one patient had cholangitis), and two patients (14.3 %) had late complications (one patient had cholangitis and one patient had cholecystitis). During the mean follow-up period of 298 days (range 89-465 days), six patients (42.9 %) developed stent occlusion caused by tumor ingrowth or overgrowth (n = 5) and sludge (n = 1). Median stent patency and overall survival times were 281 days (95 % CI 175.9-386.1 days) and 381 days (95 % CI 291.4-470.6 days), respectively. The use of the newly designed Y-configured bilateral SEMS is feasible and effective for hilar biliary obstruction using port docking deployment.

Using a large, current, regional registry of percutaneous coronary interventions (PCI), we identified risk factors for postprocedure vascular complications and developed a scoring system to estimate individual patient risk. A vascular complication (access-site injury requiring treatment or bleeding requiring transfusion) is a potentially avoidable outcome of PCI. Data were collected on 18,137 consecutive patients undergoing PCI in northern New England from January 1997 to December 1999. Multivariate regression was used to identify characteristics associated with vascular complications and to develop a scoring system to predict risk. The rate of vascular complication was 2.98% (541 cases). Variables associated with increased risk in the multivariate analysis included age >or=70, odds ratio (OR) 2.7, female sex (OR 2.4), body surface area <1.6 m(2) (OR 1.9), history of congestive heart failure (OR 1.4), chronic obstructive pulmonary disease (OR 1.5), renal failure (OR 1.9), lower extremity vascular disease (OR 1.4), bleeding disorder (OR 1.68), emergent priority (OR 2.3), myocardial infarction (OR 1.7), shock (1.86), >or=1 type B2 (OR 1.32) or type C (OR 1.7) lesions, 3-vessel PCI (OR 1.5), use of thienopyridines (OR 1.4) or use of glycoprotein IIb/IIIa receptor inhibitors (OR 1.9). The model performed well in tests for significance, discrimination, and calibration. The scoring system captured 75% of actual vascular complications in its highest quintiles of predicted risk. Predicting the risk of post-PCI vascular complications is feasible. This information may be useful for clinical decision-making and institutional efforts at quality improvement.

2010-06-01

We present a case of neonatal ovarian torsion complicated by bowel obstruction and perforation and review the literature regarding the incidence of bowel obstruction in neonatal ovarian cysts, the presentation, and treatment. A term neonate was prenatally diagnosed with a cystic abdominal mass palpable on physical examination. A postnatal abdominal x-ray showed paucity of gas in the left hemiabdomen with rightward displacement of bowel loops. Exploratory laparotomy on day 2 of life revealed a large cystic mass in the left lower quadrant consistent with a torsed left ovary, an omental band causing strangulation of the bowel mesentery, and a perforation of the distal ileum. Our literature search revealed 19 reported cases of neonatal ovarian cysts resulting in bowel obstruction. Infants may present with a palpable abdominal mass, respiratory distress, as well as signs and symptoms of intestinal obstruction. Two mechanisms exist for bowel obstruction: adhesions caused by a torsed necrotic ovary and mass effect of a large ovarian cyst, often measuring 9 to 10 cm in diameter. Options to treat ovarian cysts include antenatal or postnatal aspiration, laparoscopy, and laparotomy. Cysts less than 4 to 5 cm can be observed, whereas operative intervention is indicated in symptomatic cases and in persistent or enlarging ovarian cysts. Copyright 2010 Elsevier Inc.

Klemmer, A; Greulich, T; Koczulla, A R; Vogelmeier, C F

2014-04-01

Chronic obstructive pulmonary disease (COPD) is a very common chronic disease with increasing prevalence. Inhaled particles and gases (in particular tobacco smoke) induce chronic inflammation of the airways accompanied by a not fully reversible airflow limitation. Destruction of lung tissue and deterioration of gas exchange may follow. In parallel, several comorbidities can be observed. The COPD assessment was revised and now takes into account lung function, the patients' symptoms, and history of exacerbations. More recently, several new long-acting bronchodilators received approval. Combination products, consisting of long-acting β2-agonists and long-acting anticholinergics, and a new combination of a long-acting β-agonist and an inhaled corticosteroid will follow in the near future. Smoking cessation is of central importance.

CFTR dysfunction in cystic fibrosis and chronic obstructive pulmonary disease.

PubMed

Fernandez Fernandez, Elena; de Santi, Chiara; De Rose, Virginia; Greene, Catherine M

2018-05-11

Obstructive lung diseases such as cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD) are causes of high morbidity and mortality worldwide. CF is a multiorgan genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene and is characterized by progressive chronic obstructive lung disease. Most cases of COPD are a result of noxious particles, mainly cigarette smoke but also other environmental pollutants. Areas covered: Although the pathogenesis and pathophysiology of CF and COPD differ, they do share key phenotypic features and because of these similarities there is great interest in exploring common mechanisms and/or factors affected by CFTR mutations and environmental insults involved in COPD. Various molecular, cellular and clinical studies have confirmed that CFTR protein dysfunction is common in both the CF and COPD airways. This review provides an update of our understanding of the role of dysfunctional CFTR in both respiratory diseases. Expert Commentary: Drugs developed for people with CF to improve mutant CFTR function and enhance CFTR ion channel activity might also be beneficial in patients with COPD. A move toward personalized therapy using, for example, microRNA modulators in conjunction with CFTR potentiators or correctors, could enhance treatment of both diseases.

Introduction: Out of all respiratory diseases COPD is the leading cause of death and is characterized with diffuse non-reversible airway obstruction. Many various components play role in development and progression of this disease, while COPD risk factors play the most prominent role. Further progress in healthcare system development around COPD in Ukraine requires analysis of legislation, regulating pulmonological medical service in Ukraine. The aim: To analyze the influence of major risk factors on the development of chronic obstructive pulmonary disease and to determine key legislative aspects of the organization of medical care for COPD patients in Ukraine. Materials and methods: 50 medical literature sources were systematically reviewed as the material for the research of COPD risk factors and their impact on studies disease. Also, an analysis of existing legislative acts regulating the pulmonological medical care in Ukraine, specifically, in patients with COPD, was conducted. Conclusions: There is a need to develop and implement a set of organizational and medical measures aiming at addressing the priorities of public healthcare, and specifically improvement of the quality of medical care for patients with chronic obstructive pulmonary disease in Ukraine.

Our goal is to determine short-term intraindividual biologic and measurement variability in spirometry of patients with a wide range of stable chronic obstructive pulmonary disease severity, using datasets from the National Emphysema Treatment Trial (NETT) and the Lung Health Study (LHS). This may be applied to determine criteria that can be used to assess a clinically meaningful change in spirometry. A total of 5,886 participants from the LHS and 1,215 participants from the NETT performed prebronchodilator spirometry during two baseline sessions. We analyzed varying criteria for absolute and percent change of FEV(1) and FVC to determine which criterion was met by 90% of the participants. The mean +/- SD FEV(1) for the initial session was 2.64 +/- 0.60 L (75.1 +/- 8.8% predicted) for the LHS and 0.68 +/- 0.22 L (23.7 +/- 6.5% predicted) for the NETT. The mean +/- SD number of days between test sessions was 24.9 +/- 17.1 for the LHS and 85.7 +/- 21.7 for the NETT. As the degree of obstruction increased, the intersession percent difference of FEV(1) increased. However, the absolute difference between tests remained relatively constant despite the severity of obstruction (0.106 +/- 0.10 L). Over 90% of participants had an intersession FEV(1) difference of less than 225 ml irrespective of the severity of obstruction. Absolute changes in FEV(1) rather than percent change should be used to determine whether patients with chronic obstructive pulmonary disease have improved or worsened between test sessions.

Occupational exposure to dust and lung disease among sheet metal workers.

Hunting, K L; Welch, L S

1993-01-01

A previous large medical survey of active and retired sheet metal workers with 20 or more years in the trade indicated an unexpectedly high prevalence of obstructive pulmonary disease among both smokers and non-smokers. This study utilised interviews with a cross section of the previously surveyed group to explore occupational risk factors for lung disease. Four hundred and seven workers were selected from the previously surveyed group on the basis of their potential for exposure to fibreglass and asbestos. Selection was independent of health state, and excluded welders. A detailed history of occupational exposure was obtained by telephone interview for 333 of these workers. Exposure data were analysed in relation to previously collected data on chronic bronchitis, obstructive lung disease, and personal characteristics. Assessment of the effects of exposure to fibreglass as distinct from the effects of exposure to asbestos has been difficult in previous studies of construction workers. The experienced workers studied here have performed a diversity of jobs involving exposure to many different types of materials, and this enabled exposure to each dust to be evaluated separately. The risk of chronic bronchitis increased sharply by pack-years of cigarettes smoked; current smokers had a double risk compared with those who had never smoked or had stopped smoking. The occurrence of chronic bronchitis also increased with increasing duration of exposure to asbestos. Workers with a history of high intensity exposure to fibreglass had a more than doubled risk of chronic bronchitis. Obstructive lung disease, defined by results of pulmonary function tests at the medical survey, was also related to both smoking and occupational risk factors. Number of pack years smoked was the strongest predictor of obstructive lung disease. Duration of direct and indirect exposure to welding fume was also a positive predictor of obstructive lung disease. Duration of exposure to asbestos was significantly associated with obstructive lung disease but the dose-response relation was inconsistent, especially for those with higher pack-years of smoking exposure. Exposure to fibreglass was not a risk factor for obstructive lung disease. PMID:8507596

The covered self-expandable metal stent (CMS) was developed to prevent tumor ingrowth-induced stent occlusion during the treatment of malignant biliary obstruction. However, complications such as cholecystitis, pancreatitis, and stent migration can occur after the endoscopic insertion of CMSs. The aim of the present study was to assess the efficacy and safety of a double-layered CMS (DCMS) for the management of malignant bile duct obstruction. DCMSs were endoscopically introduced into 59 patients with unresectable malignant extrahepatic biliary obstruction at four tertiary referral centers, and the patient medical records were retrospectively reviewed. Both the technical and functional success rates were 100%. Procedure-related complications including pancreatitis, cholangitis, stent migration, and liver abscess occurred in five patients (8.5%). The median follow-up period was 265 days (range, 31 to 752 days). Cumulative stent patency rates were 68.2% and 40.8% at 6 and 12 months, respectively. At the final follow-up, the rate of stent occlusion was 33.9% (20/59), and the median stent patency period was 276 days (range, 2 to 706 days). The clinical outcomes of DCMSs were comparable to the outcomes previously reported for CMSs with respect to stent patency period and complication rates.

Being overweight or obese is associated with a higher rate of survival in patients with advanced chronic obstructive pulmonary disease (COPD). This paradoxical relationship indicates that the influence of nutritional status on functional parameters should be further investigated. To investigate the impact of nutritional status on body composition, exercise capacity and respiratory muscle strength in severe chronic obstructive pulmonary disease patients. Thirty-two patients (nine women) were divided into three groups according to their body mass indices (BMI): overweight/obese (25 < or = BMI < or = 34.9 kg/m(2), n=8), normal weight (18.5 < or = BMI < or = 24.9 kg/m(2), n=17) and underweight (BMI <18.5 kg/m(2), n=7). Spirometry, bioelectrical impedance, a six-minute walking distance test and maximal inspiratory and expiratory pressures were assessed. Airway obstruction was similar among the groups (p=0.30); however, overweight/obese patients had a higher fat-free mass (FFM) index [FFMI=FFM/body weight(2) (mean+/-SEM: 17+/-0.3 vs. 15+/-0.3 vs. 14+/-0.5 m/kg(2), p<0.01)], exercise capacity (90+/-8 vs. 79+/-6 vs. 57+/-8 m, p=0.02) and maximal inspiratory pressure (63+/-7 vs. 57+/-5 vs. 35+/-8 % predicted, p=0.03) in comparison to normal weight and underweight patients, respectively. In addition, on backward multiple regression analysis, FFMI was the unique independent predictor of exercise capacity (partial r=0.52, p<0.01). Severe chronic obstructive pulmonary disease (COPD) patients who were overweight or obese had a greater FFM, exercise capacity and inspiratory muscle strength than patients with the same degree of airflow obstruction who were of normal weight or underweight, and higher FFM was independently associated with higher exercise capacity. These characteristics of overweight or obese patients might counteract the drawbacks of excess weight and lead to an improved prognosis in COPD.

Post-obstructive pulmonary edema is thought to occur from hemodynamic changes secondary to forced inspiration against the closed airway due to acute or chronic airway obstruction. We report a case of a 13 month-old boy who developed pulmonary edema from aspirated foreign body, nuts. He underwent emergency bronchoscopy to confirm the clinical diagnosis of aspirated nuts in the trachea and nuts were removed endoscopically. His trachea was then intubated and he was mechanically ventilated with oxygen. He developed florid pulmonary edema early in the course with tracheal obstruction and during endoscopic removal of nuts. After removal of obstruction he was ventilated mechanically and pulmonary edema cleared rapidly. Aspirated nuts obstructing trachea can induce obstructive pulmonary edema. Early recognition of foreign body obstruction based on clinical history and its removal resolved pulmonary edema.

Giant Meckel’s diverticulum: An exceptional cause of intestinal obstruction

PubMed Central

Akbulut, Sami; Yagmur, Yusuf

2014-01-01

Meckel’s diverticulum (MD) results from incomplete involution of the proximal portion of the vitelline (also known as the omphalomesenteric) duct during weeks 5-7 of foetal development. Although MD is the most commonly diagnosed congenital gastrointestinal anomaly, it is estimated to affect only 2% of the population worldwide. Most cases are asymptomatic, and diagnosis is often made following investigation of unexplained gastrointestinal bleeding, perforation, inflammation or obstruction that prompt clinic presentation. While MD range in size from 1-10 cm, cases of giant MD (≥ 5 cm) are relatively rare and associated with more severe forms of the complications, especially for obstruction. Herein, we report a case of giant MD with secondary small bowel obstruction in an adult male that was successfully managed by surgical resection and anastomosis created with endoscopic stapler device (80 mm, endo-GIA stapler). Patient was discharged on post-operative day 6 without any complications. Histopathologic examination indicated Meckel’s diverticulitis without gastric or pancreatic metaplasia. PMID:24672650

'A good shepherd, but with obstructive sleep apnoea syndrome': traditional uvulectomy case series and literature review.

2011-09-01

In the West, removal of the uvula is predominantly undertaken as part of palatal surgery, in cases of obstructive sleep apnoea. In the developing world, such as the Middle East and Africa, uvulectomy is a more common practice. The uvula is removed for curative or preventive purposes, or as part of ritual practice. Due to immigration from developing to developed world countries, and to Western doctors working abroad, such doctors are increasingly being confronted with unfamiliar traditional healing practices, within a medical context. The Medline and Embase online databases were systematically searched for literature on traditional uvulectomy. We present a review of this literature. We also present the first report, to our best knowledge, of obstructive sleep apnoea as a late complication of traditional uvulectomy. Traditional uvulectomy may be complicated by post-operative haemorrhage and local infections, among many other problems. We report cases of obstructive sleep apnoea and snoring caused by palatal stenosis resulting from traditional uvulectomy during childhood.

The goal of this study was to prove the possibility of using silicone stents broadly used for human medicine in canine obstructive tracheal disease. A silicone stent anatomically designed for canine trachea was tested on 5 beagle dogs for 8 weeks. The stent was carefully inserted using a newly developed delivery device under fluoroscopic guidance. There were no technical difficulties in placing the stent during the procedure. Previously reported complications of airway stenting such as stent migration or granulation tissue formation did not occur in any of the cases. In addition, removal of the stent was as simple as inserting it, and complications were absent. The stent introduced in this study could possibly be applied to various canine obstructive tracheal diseases.

Comprehensive disease management programmes for chronic disease aim to improve patient outcomes and reduce health-care utilization. Readmission rates are often used as an outcome measure of effectiveness. This study aimed to document readmission rates, and risk for early and late readmission, for patients discharged from the Royal Melbourne Hospital with a disease diagnosis of chronic heart failure (CHF), chronic obstructive pulmonary disease (COPD) or diabetes mellitus compared to those with other general medical conditions. Eighty five (8.6%) of patients were readmitted within 28 days and 183 (20.8%) were readmitted between 29 and 180 days. No risk factors for early readmission were identified. Patients with a primary disease diagnosis of CHF and COPD are at increased risk of late readmissions (29-180 days).

Posthypercapnic alkalosis (PHA) is frequently overlooked as a complication of mechanical ventilation in patients with exacerbation of chronic obstructive pulmonary disease (COPD). The current study was conducted to determine the incidence, risk factors for development and effect on outcome of PHA. Eighty-four patients (62 +/- 11 years, range 42-78 years, M:F 58: 26) with exacerbation of COPD with underlying chronic hypercapnic respiratory failure requiring mechanical ventilation were included in a retrospective fashion. PHA was defined as static or rising serum bicarbonate levels, 72 hours or more after return of PaCO2 to baseline, with concurrent pH > 7.44. Development of PHA was noted in 17 patients (20.2%). Corticosteroid use >or=10 days during the hospital stay was an independent risk factor for development of PHA (Adjusted OR, 95% CI: 9.4, 1.6-55.3; P = 0.013). Development of PHA was associated with an increased incidence of ventilator dependence (64.7% vs. 37.3%, OR, 95% CI: 3.1, 1.1-9.4, P = 0.04) and duration of ICU stay (14.7 +/- 6.7 vs. 9.5 +/- 5.9, P = 0.01) but no increase in hospital mortality (43.3% vs. 41.2%, P = NS). It is concluded that PHA is a common complication in patients with exacerbation of COPD requiring mechanical ventilation and is associated with increased incidence of ventilator dependence and ICU stay.

In very low birth weight infants abdominal emergency surgery may result in ileostomy formation. We observed a frequent stoma complications in these patients. This retrospective analysis put light on ileostomy-related problems and complications in very low birth weight (VLBW) infants. In a seven-year retrospective chart review (2008 - 2014) infants with ileostomy formation weighing less than 1500 grams at time of operation were identified and reviewed. Data analysis included demographic data, complications and short term outcomes. Thirty patients were included. Ileostomy was formed for spontaneous intestinal perforation (SIP) (n=17), meconium obstruction of prematurity (MOP) (n=6), midgut volvulus (MV) (n=5), necrotizing enterocolitis (NEC) (n=1) and Hirschsprung's disease (HD) (n=1). Three patients died before ileostomy reversal was considered. In seven patients planned ileostomy reversal was done. Twenty infants had stoma related complications (stoma prolapse, prestomal obstruction, stoma retraction, high output stoma, peristomal skin excoriation, and stomal ischemia). Complications did not correlate with underlying diseases. Stomal complications necessitated earlier stoma reversal (mean 62 days). Postoperative complications after stoma reversal occurred in three children (wound dehiscence, adhesion ileus, anastomotic stricture). Although ileostomy related complications are frequent in very low birth weight infants, mortality is low. Morbidity is manageable.

The aim of this study is to evaluate the efficacy and safety of interventional radiology procedures in the treatment of major urological complications after kidney transplantation. Between 2000 and 2010, 1,146 kidney transplants were performed at our institution. A total of 146 major complications occurred, including 77 obstructions, 36 leaks and 33 associated perigraft fluid collections. Percutaneous treatment was carried out in 118/146 complications in 91 patients. In the case of stenosis-obstruction and fistulas (104 complications), the first therapeutic step was placement of a nephrostomy catheter, followed by balloon ureteroplasty, placement of external-internal catheters and double-J stents; 14/33 collections were drained under ultrasound guidance. In all 118 percutaneous interventions, we were able to place a nephrostomy or drainage catheter, with a technical success rate of 100 %. The long-term success rate was 49.6 %: in 57/115 (three patients were lost to follow-up) we obtained the complete resolution of the complication. The procedure-related mortality rate was 0 %. There was only one major complication and the rate of minor complications was 14.4 %. Interventional radiology is the first choice option in the treatment of urological complications after kidney transplantation.

To compare the impact of a library of pulmonary rehabilitation videotapes versus an older videotape and usual care on quality of life and ability to perform activities of daily living in persons with chronic obstructive pulmonary disease. Two hundred fourteen patients diagnosed with chronic obstructive pulmonary disease, emphysema, or chronic bronchitis were recruited and randomized to receive customized videotapes, standard videotapes, or usual care. Outcome measures included the Fatigue Impact Scale, Seattle Obstructive Lung Disease Questionnaire, and the SF-36(R) Health Survey. Differences in coping skills and emotional functioning on the Seattle Obstructive Lung Disease Questionnaire were found among the 174 subjects who completed the study. The customized videotape group improved by 8.6 and 4.8 points, respectively, whereas the score of the other groups decreased by less than 1 point for the coping skills, and the scores of the standard video and the control groups decreased by 3.0 and 2.1 points, respectively, for emotional functioning (P < .05, all comparisons). The scores using the Fatigue Impact Scale also improved for the customized videotape group, whereas the scores of the others remained unchanged. Videotape users demonstrated better conversion to and retention of exercise habits, with over 80% of customized videotape subjects who reported exercise habits at baseline continuing the habits as compared with 40% in the usual care group. Sedentary subjects at baseline were more likely to begin and maintain exercise if randomized to videotapes. These findings demonstrate increased quality of life, lower fatigue, and better compliance with a prescribed exercise regimen among subjects using the customized videotapes. There was a significant improvement in emotional functioning and coping skills among customized videotape subjects.

Global Initiative for Chronic Obstructive Lung Disease strategy for the diagnosis, management and prevention of chronic obstructive pulmonary disease: an Asia-Pacific perspective.

PubMed

2005-01-01

Chronic obstructive pulmonary disease (COPD) is a major public health problem and its prevalence and mortality are increasing throughout the world, including the Asia-Pacific region. To arrest these worldwide trends, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) Expert Panel's global strategy for the diagnosis, management, and prevention of COPD was published in 2001. Based on recently published clinical trials, the GOLD statement was updated in 2003. The Asia-Pacific COPD Roundtable Group, a taskforce of expert respirologists from the Asia-Pacific region, has recently formulated a consensus statement on implementation of the GOLD strategy for COPD in the Asia-Pacific region. The key issues identified by the COPD Roundtable Group for comment are: (i) where there is no access to spirometry, diagnosis of COPD could be suspected on the basis of history, symptoms and physical signs; (ii) inhaled bronchodilators are the preferred regular treatment for COPD in the region, but oral bronchodilators may be considered if the cost of inhaled bronchodilators is a barrier to treatment; (iii) the use of a Metered Dose Inhaler with spacer in place of a nebulizer is recommended in the treatment of acute airflow obstruction in patients with COPD; (iv) influenza vaccination is recommended for all patients with COPD in communities where there is a high likelihood of Severe Acute Respiratory Syndrome; and (v) simplified pulmonary rehabilitation programmes should be established in areas where comprehensive programmes are unavailable. Physical exercise training and education on smoking cessation should be core elements of any rehabilitation program. In summary, the COPD Roundtable Group supports implementation of the GOLD strategy for the diagnosis, management and prevention of COPD in the Asia-Pacific region, subject to the additions and modifications to the guidelines suggested above.

Global estimates suggest that Chronic Obstructive Pulmonary Disease (COPD) is emerging as a leading cause of death in developing countries but there are few spirometry-based general population data on its prevalence and risk factors in sub-Saharan Africa. We used the Burden of Obstructive Lung Disease (BOLD) protocol to select a representative sample of adults aged 40 years and above in Ile-Ife, Nigeria. All the participants underwent spirometry and provided information on smoking history, biomass and occupational exposures as well as diagnosed respiratory diseases and symptoms. Chronic Airflow Obstruction (CAO) was defined as the ratio of post-bronchodilator (BD) one second Forced Expiratory Volume (FEV1) to Forced Vital Capacity (FVC) below the lower limit of normal (LLN) of the population distribution for FEV1/FVC. The overall prevalence of obstruction (post-BD FEV1/FVC < LLN) was 7.7% (2.7% above LLN) using Global Lung Function Initiative (GLI) equations. It was associated with few respiratory symptoms; 0.3% reported a previous doctor-diagnosed chronic bronchitis, emphysema or COPD. Independent predictors included a lack of education (OR 2.5, 95% CI: 1.0, 6.4) and a diagnosis of either TB (OR 23.4, 95% CI: 2.0, 278.6) or asthma (OR 35.4, 95%CI: 4.9, 255.8). There was no association with the use of firewood or coal for cooking or heating. The vast majority of this population (89%) are never smokers. We conclude that the prevalence of CAO is low in Ile-Ife, Nigeria and unrelated to biomass exposure. The key independent predictors are poor education, and previous diagnosis of tuberculosis or asthma.

There is a growing body of evidence to support the direct link between obstructive bladder dysfunction and erectile dysfunction (ED). However, there have been few pathophysiological studies to determine the relationship between lower urinary tract syndrome (LUTS) and ED. As the transforming growth factor-β1 (TGF-β1) that induces the synthesis of collagen in the penile tissues is critical for the development of ED, the first aim of this study was to investigate the expression of TGF-β1 in the penis from male rabbits with chronic partial bladder outlet obstruction (PBOO). Besides, it has been suggested that oxidative stress plays a significant role in the pathophysiological mechanism of ED. Thus, the second aim of this study was to further investigate whether the urinary or serum oxidative stress markers are involved in chronic PBOO-induced penile dysfunction. A total of 16 male New Zealand White rabbits were separated equally into four groups: a control group and PBOO groups obstructed for 2, 4 and 8 weeks respectively. Using the RT-PCR and Western blot analysis, a progressive increase of TGF-β1 in penis was found at 2, 4 and 8 weeks after obstruction. Moreover, the biomarkers for oxidative stress or oxidative damage were significantly detected in the penis of rabbits after PBOO, which include the enhancement of 8-hydroxy-2'-deoxyguanosine (8-OHdG) in urine and plasma, plasma malondialdehyde (MDA) and total antioxidant capacity (TAC), as well as reduction of glutathione (GSH). On the basis of our results, the increase of TGF-β1 and elevated systemic oxidative stress may play key roles to contribute to penile dysfunction after chronic PBOO. © 2011 The Authors.

Wt-1 Expression Linked to Nitric Oxide Availability during Neonatal Obstructive Nephropathy

PubMed Central

Mazzei, Luciana; Manucha, Walter

2013-01-01

The wt-1 gene encodes a zinc finger DNA-binding protein that acts as a transcriptional activator or repressor depending on the cellular or chromosomal context. The wt-1 regulates the expression of a large number of genes that have a critical role in kidney development. Congenital obstructive nephropathy disrupts normal renal development and causes chronic progressive interstitial fibrosis, which contributes to renal growth arrest, ultimately leading to chronic renal failure. Wt-1 is downregulated during congenital obstructive nephropathy, leading to apoptosis. Of great interest, nitric oxide bioavailability associated with heat shock protein 70 (Hsp70) interaction may modulate wt-1 mRNA expression, preventing obstruction-induced cell death during neonatal unilateral ureteral obstruction. Moreover, recent genetic researches have allowed characterization of many of the complex interactions among the individual components cited, but the realization of new biochemical, molecular, and functional experiments as proposed in our and other research labs allows us to establish a deeper level of commitment among proteins involved and the potential pathogenic consequences of their imbalance.

Messenger, Robert W

2012-01-01

Exacerbation and frequent rehospitalization in chronic obstructive pulmonary disease exacts a heavy toll on the US health care system. To address these issues, new initiatives have been proposed that are largely based on financial penalties to promote patient education and postdischarge care. However, as laudable as these goals are, improving outcomes in the chronic obstructive pulmonary disease population is more confounding than it may first appear. Chronic hypoxia, cognitive dysfunction, poor nutrition, and economic disadvantage are just a few of the challenges that require creative solutions and ongoing support. Case managers need to utilize all the potential products and services that can assist in improving outcomes for these patients. Durable medical equipment providers are often viewed as purveyors of medical equipment that offer little in the form of clinical support. However, in many cases these providers represent an overlooked resource that provides individualized, highly structured patient education and ongoing support programs. The challenge is in identifying those durable medical equipment providers that offer patients contemporary technology, and have both the resources and the commitment to provide patient support that is amenable to the goals of the hospital. This article reviews many of the confounding issues that contribute to the frequent rehospitalization of chronic obstructive pulmonary disease patients. Recommendations to improve patient education and oxygen therapy outcomes are provided along with suggestions to aid in the vetting of durable medical equipment providers. Acute care hospitals, long-term acute care hospitals, extended care facilities, integrated delivery systems. 1. An understanding of the complex variables that play in the management of chronic obstructive pulmonary disease will help the case manager to plan an effective course of care. 2. Case managers need to ensure that patients receive long-term oxygen technology that supports their lifestyle, promotes compliance, and ultimately achieves the desired outcomes. 3. Case managers must advocate for coordinated, ongoing patient education and stress the need for continuing reinforcement. 4. Case managers must ensure that patients under their care be matched with durable medical equipment providers that provide the technology and support that favors positive clinical outcomes.

Role of Oxidative Stress in the Neurocognitive Dysfunction of Obstructive Sleep Apnea Syndrome.

PubMed

Zhou, Li; Chen, Ping; Peng, Yating; Ouyang, Ruoyun

2016-01-01

Obstructive sleep apnea syndrome (OSAS) is characterized by chronic nocturnal intermittent hypoxia and sleep fragmentations. Neurocognitive dysfunction, a significant and extraordinary complication of OSAS, influences patients' career, family, and social life and reduces quality of life to some extent. Previous researches revealed that repetitive hypoxia and reoxygenation caused mitochondria and endoplasmic reticulum dysfunction, overactivated NADPH oxidase, xanthine oxidase, and uncoupling nitric oxide synthase, induced an imbalance between prooxidants and antioxidants, and then got rise to a series of oxidative stress (OS) responses, such as protein oxidation, lipid peroxidation, and DNA oxidation along with inflammatory reaction. OS in brain could trigger neuron injury especially in the hippocampus and cerebral cortex regions. Those two regions are fairly susceptible to hypoxia and oxidative stress production which could consequently result in cognitive dysfunction. Apart from continuous positive airway pressure (CPAP), antioxidant may be a promising therapeutic method to improve partially reversible neurocognitive function. Understanding the role that OS played in the cognitive deficits is crucial for future research and therapeutic strategy development. In this paper, recent important literature concerning the relationship between oxidative stress and cognitive impairment in OSAS will be summarized and the results can provide a rewarding overview for future breakthrough in this field.

Management of the colonic volvulus in 2016.

Perrot, L; Fohlen, A; Alves, A; Lubrano, J

2016-06-01

Colonic volvulus is the third leading cause of colonic obstruction worldwide, occurring at two principal locations: the sigmoid colon and cecum. In Western countries, sigmoid volvulus preferentially affects elderly men whereas cecal volvulus affects younger women. Some risk factors, such as chronic constipation, high-fiber diet, frequent use of laxatives, personal past history of laparotomy and anatomic predispositions, are common to both locations. Clinical symptomatology is non-specific, including a combination of abdominal pain, gaseous distention, and bowel obstruction. Abdominopelvic computerized tomography is currently the gold standard examination, allowing positive diagnosis as well as detection of complications. Specific management depends on the location, patient comorbidities and colonic wall viability, but treatment is an emergency in every case. If clinical or radiological signs of gravity are present, emergency surgery is mandatory, but is associated with high morbidity and mortality rates. For sigmoid volvulus without criteria of gravity, the ideal strategy is an endoscopic detorsion procedure followed, within 2 to 5 days, by surgery that includes a sigmoid colectomy with primary anastomosis. Exclusively endoscopic therapy must be reserved for patients who are at excessive risk for surgical intervention. In cecal volvulus, endoscopy has no role and surgery is the rule.

Bronchiolitis obliterans syndrome (BOS) is a serious complication of chronic GVHD (cGVHD) following HSCT (hematopoietic SCT). The clinical diagnosis of BOS is based on pulmonary function test (PFT) abnormalities including: FEV1<75% predicted and obstructive FEV1/VC ratio, calculated using reference equations. We sought to determine if the frequency of clinical diagnoses and severity of BOS would be altered by using the recommended NHANES III vs older equations (Morris/Goldman/Bates, MGB) in 166 cGVHD patients, median age 48 (range: 12–67). We found that NHANES III equations significantly increased the prevalence of BOS, with an additional 11% (18/166) meeting diagnostic criteria by revealing low FEV1 (<75%) (P<0.0001), and six additional patients by obstructive ratio (vs MBG). Collectively, this led to an increase of BOS incidence from 17 (29/166) to 29% (41/166). For patients with severe BOS, (FEV1<35%), NHANES III equations correctly predicted death 71.4% vs 50% using MGB. In conclusion, the use of NHANES III equations markedly increases the proportion of cases meeting diagnostic criteria for BOS and improves prediction of survival. PMID:24419526

Chronic obstructive pulmonary disease (COPD) is a debilitating disease resulting in frequent hospitalizations and increased healthcare costs. As leaders of multidisciplinary teams, acute care nurse leaders are challenged to reduce readmissions and costs. In October 2014, the Centers for Medicare and Medicaid Services expanded readmission penalties for 30-day readmissions to include COPD, making this an important issue for nurse leaders. This article describes how a regional medical center was able to decrease COPD readmissions.

Many patients with malignant gastroduodenal obstruction have an unresectable primary lesion and distant metastases, which may prompt palliative management to allow the patient to eat and to improve the quality of life. Intraluminal metallic stent implantation (MSI) under fluoroscopic guidance has been reported to be an effective option for symptomatic relief in these patients, with a good safety record. An alternative, dual interventional therapy (DIT), has been used during the last decade, in which prosthesis insertion is followed by intra-arterial chemotherapy via the tumor-feeding arteries. The aim of this study was to compare success rates, complication rates, and survival timemore » between MSI and DIT in patients who presented with gastroduodenal obstruction from advanced upper gastrointestinal tract cancer. All consecutive patients with malignant gastroduodenal obstruction seen at our center between October 2002 and August 2007 were retrospectively studied. Patients were treated palliatively by either MSI or DIT by the patient's or the next of kin's decision. Outcomes included technical and clinical success, complication rates, and survival. Of the 164 patients with malignant gastric and duodenal outlet obstructions, 80 (49%) underwent stent insertion as the primary therapy, while the remaining 84 (51%) received DIT. Clinical characteristics were similar between the two groups. In the MSI cohort initial stent implantation was successful in 73 patients (91%), two stents were used in 5 patients, and delayed additional stent insertion for stent obstruction related to tumor overgrowth was required in 3 patients during follow-up. In the DIT cohort the technical success rate was 94%, 3 patients required two stents, and stent obstruction occurred in 2 patients after initial stent placement. Early postprocedural clinical success, indicated by average dysphagia score, improved significantly in both groups: MSI group, from 4.56 to 1.51 (P < 0.01); and DIT group, from 4.38 to 1.48 (p < 0.01). There were no short-term complications. Late complications including hematemesis (n = 3), migration (n = 12), and stent occlusion due to tumor overgrowth (n = 5) were evenly distributed between the groups. In the DIT group chemotherapy-induced neutropenia and transient renal dysfunction were detected in six patients, which improved after symptomatic management. Mean survival time after the procedure was 5.9 and 11.1 months for MSI and DIT, respectively (P < 0.001). In conclusion, both MSI and DIT offer effective palliation for malignant gastroduodenal obstruction, but DIT appears to offer superior survival over MSI alone. Ideally, a prospective randomized trial comparing these two techniques should be carried out to validate this result.« less

Pancreatic ductal obstruction leading to ductal dilation and recurrent pancreatitis is uncommon in children. Treatment is dependent upon etiology but consists of decompression of the pancreatic duct (PD) proximally, if possible, by endoscopic retrograde cholangiopancreatography (ERCP) intervention or surgical decompression with pancreaticojejunal anastomosis. After institutional review board approval, we retrospectively reviewed the records for 2 children who underwent lateral pancreaticojejunostomy for pancreatic ductal dilation. Data, including demographics, diagnostic studies, operative details, complications, outcomes, and follow-up, were analyzed. Case 1 was a 4-year-old female with pancreatic ductal obstruction with multiple episodes of recurrent pancreatitis and failure of ERCP to clear her PD of stones. She underwent a laparoscopic cholecystectomy with a lateral pancreaticojejunostomy (Puestow procedure). She recovered well with no further episodes of pancreatitis and normal pancreatic function 4 years later. Case 2 was a 2-year-old female who developed recurrent pancreatitis and was found to have papillary stenosis and long common bile-PD channel. Despite multiple sphincterotomies, laparoscopic cholecystectomy, and laparoscopic hepaticoduodenostomy, she continued to experience episodes of pancreatitis. She underwent a laparoscopy converted to open lateral pancreaticojejunostomy. Her recovery was also smooth having had no episodes of pancreatitis or hospital admissions for over 2 years following the Puestow. Indication for lateral pancreaticojejunostomy or Puestow procedure is rare in children and even less often performed using laparoscopy. In our small experience, both patients with pancreatic ductal obstruction managed with Puestow's procedure enjoy durable symptom and pain relief in the long term.

Pannus formation after aortic valve replacement is not common, but obstruction due to chronic pannus is one of the most serious complications of valve replacement. The causes of pannus formation are still unknown and effective preventive methods have not been fully elucidated. We reviewed our clinical experience of all patients who underwent reoperation for prosthetic aortic valve obstruction due to pannus formation between 1973 and 2004. We compared the initial 18-year period of surgery, when the Björk-Shiley tilting-disk valve was used, and the subsequent 13-year period of surgery, when the St. Jude Medical valve was used. Seven of a total of 390 patients (1.8%) required reoperation for prosthetic aortic valve obstruction due to pannus formation. All seven patients were women; four patients underwent resection of the pannus and three patients needed replacement of the valve. The frequency of pannus formation in the early group was 2.4% (6/253), whereas it was 0.73% (1/137) in the late group (P < 0.05). Pannus was localized at the minor orifice of the Björk-Shiley valve in the early group and turbulent transvalvular blood flow was considered to be one of the important factors triggering its growth. We also consider that small bileaflet valves have the possibility of promoting pannus formation and that the implantation of a larger prosthesis can contribute to reducing the occurrence of pannus.

Cigarette smoking is a major cause of chronic obstructive pulmonary disease, (COPD) but many persons with COPD continue to smoke. Quitting can help prevent the development of and complications from COPD. This study examined whether smoking and cessation behaviors differed among adults with a) COPD, b) asthma, c) other chronic conditions only, or d) no chronic conditions. Smoking and chronic disease status was obtained from 488,909 adults aged > 18 years using the Behavioral Risk Factor Surveillance System; 9,476 current smokers and recent quitters in 5 states responded to additional questions about cessation. We computed age-adjusted prevalence of smoking and past-year quit attempts, and used bivariate and multivariable logistic regression to identify correlates of past-year quit attempts. Similar to the overall sample, in the 5-state sample, 47.3% of adults with COPD were current smokers versus 23.1% of those with asthma, 28.8% of adults with other chronic conditions, and 20.0% of those with no chronic conditions. Those with COPD did not differ significantly from those with asthma, other chronic diseases, or no chronic disease in having made a past-year quit attempt (59.7% versus 64.0%, 61.5%, and 53.9%, respectively). Smokers with COPD were significantly more likely than those with no chronic disease to have used cessation treatment resources, including a quitline, counseling, or medication (p < 0.001). Adults with COPD were just as likely as those without COPD to make a past-year quit attempt; however, approximately 40% of smokers with COPD did not try to quit.

Bone Marrow Transplant (BMT) is a lifesaving procedure for a range of serious benign or malignant hematological conditions. A proportion of patients however will develop Graft Versus Host Disease (GVHD), acute or chronic, with serious long term sequalae. We present two cases of hematocolpos that developed in adolescence because of vaginal synechiae due to GVHD. The condition was initially asymptomatic, resolved spontaneously at first and recurred. In one girl blunt lysis of the adhesions was performed under general anesthetic, followed thereafter by local hydrocortisone and estriol treatment. Genital symptoms may not be readily reported by adolescents post BMT. Physicians should be aware of possible late effects of GVHD on genitalia, inquire about symptoms and be acquainted with addressing complications, such as vaginal obstruction. Copyright © 2018.

This article aims to review the available literature regarding the link between occupational exposure to pesticides and respiratory symptoms or diseases. Identification of epidemiological studies was performed using PubMed. 41 articles were included, 36 regarding agricultural workers and five regarding industry workers. Among the 15 cross-sectional studies focusing on respiratory symptoms and agricultural pesticide exposure, 12 found significant associations with chronic cough, wheeze, dyspnoea, breathlessness or chest tightness. All four studies on asthma found a relationship with occupational exposure, as did all three studies on chronic bronchitis. The four studies that performed spirometry reported impaired respiratory function linked to pesticide exposure, suggestive of either obstructive or restrictive syndrome according to the chemical class of pesticide. 12 papers reported results from cohort studies. Three out of nine found a significant relationship with increased risk of wheeze, five out of nine with asthma and three out of three with chronic bronchitis. In workers employed in pesticide production, elevated risks of chronic obstructive pulmonary disease (two studies out of three) and impaired respiratory function suggestive of an obstructive syndrome (two studies out of two) were reported. In conclusion, this article suggests that occupational exposure to pesticides is associated with an increased risk of respiratory symptoms, asthma and chronic bronchitis, but the causal relationship is still under debate.

Chronic intestinal pseudo-obstruction.

PubMed

Gabbard, Scott L; Lacy, Brian E

2013-06-01

Chronic intestinal pseudo-obstruction (CIP) is a rare and serious disorder of the gastrointestinal (GI) tract characterized as a motility disorder with the primary defect of impaired peristalsis; symptoms are consistent with a bowel obstruction, although mechanical obstruction cannot be identified. CIP is classified as a neuropathy, myopathy, or mesenchymopathy; it is a neuropathic process in the majority of patients. The natural history of CIP is generally that of a progressive disorder, although occasional patients with secondary CIP note significant symptomatic improvement when the underlying disorder is identified and treated. Symptoms vary from patient to patient depending on the location of the luminal GI tract involved and the degree of involvement; however, the small intestine is nearly always involved. Common symptoms include dysphagia, gastroesophageal reflux, abdominal pain, nausea, vomiting, bloating, abdominal distension, constipation or diarrhea, and involuntary weight loss. Unfortunately, these symptoms are nonspecific, which can contribute to misdiagnosis or a delay in diagnosis and treatment. Since many of the symptoms and signs suggest a mechanical bowel obstruction, diagnostic tests typically focus on uncovering a mechanical obstruction, although routine tests do not identify an obstructive process. Nutrition supplementation is required for many patients with CIP due to symptoms of dysphagia, nausea, vomiting, and weight loss. This review discusses the epidemiology, etiology, pathogenesis, diagnosis, and treatment of patients with CIP, with an emphasis on nutrition assessment and treatment options for patients with nutrition compromise.

[Acute gastric volvulus: late complication of Nissen fundoplication. Report of two cases and review of the literature].

PubMed

2014-01-01

Gastric volvulus can be classified according to etiology as primary or secondary, according to anatomy as or mesenteroaxial, and according to onset as acute or chronic. Management of secondary gastric volvulus acute should always be surgery and the choice of surgical procedure for treatment is chosen according to etiology. Adherolysis and extraction of foreign bodies (suture, mesh, and gastric band) are important in those cases associated with previous abdominal surgery. Nissen fundoplication is a safe and effective procedure. Severe late complications of laparoscopic Nissen fundoplication are extremely rare occurrences. Among the reported complications is gastric volvulus. Presentation of two cases and review of literature. Two cases of acute gastric volvulus secondary to laparoscopic Nissen fundoplication presenting with epigastric pain and nonproductive retching and treated by laparoscopy are described. Symptoms upon presentation, incidence, diagnosis, treatment and predisposing factors to gastric volvulus postfundoplication are discussed. Gastric volvulus rarely occurs as a complication of Nissen fundoplication with an incidence similar to others of late complications. The described mechanisms that originate gastric volvulus postfundoplication are related to adhesions, foreign bodies as suture (polyester), gastrostomy tubes and mesh, gastropexy and internal gastric herniation through a "transfundoplication" window. A high index of suspicion is required in those patients presenting with acute symptoms of gastric obstruction in the first year following laparoscopic Nissen fundoplication. Laparoscopic approach is safe with or without gastropexy, always correcting the underlying mechanisms that cause gastric volvulus.

This study was designed to investigate retrospectively the feasibility of transjugular insertion of biliary stent (TIBS) for the treatment of distal malignant obstructive jaundice complicated by coagulopathy. Between April 2005 and May 2010, six patients with distal malignant obstructive jaundice associated with coagulopathy that was unable to be corrected underwent TIBS at our institution for the palliation of jaundice. Patients' medical record and imaging results were reviewed to obtain information about demographics, procedure details, complications, and clinical outcomes. The intrahepatic biliary tract was successfully accessed in all six patients via transjugular approach. The procedure was technically successfully in five ofmore » six patients, with a bare-metal stent implanted after traversing the biliary strictures. One procedure failed, because the guidewire could not traverse the biliary occlusion. One week after TIBS, the mean serum bilirubin in the five successful cases had decreased from 313 {mu}mol/L (range 203.4-369.3) to 146.2 {mu}mol/L (range 95.8-223.3) and had further decreased to 103.6 {mu}mol/L (range 29.5-240.9) at 1 month after the procedure. No bleeding, sepsis, or other major complications were observed after the procedure. The mean survival of these five patients was 4.5 months (range 1.9-5.8). On imaging follow-up, there was no evidence of stent stenosis or migration, with 100 % primary patency. When the risks of hemorrhage from percutaneous transhepatic cholangiodrainage are high, TIBS may be an effective alternative for the treatment of distal malignant obstructive jaundice.« less

In this paper, a deep learning method has been raised to build an automatic classification algorithm of severity of chronic obstructive pulmonary disease. Large sample clinical data as input feature were analyzed for their weights in classification. Through feature selection, model training, parameter optimization and model testing, a classification prediction model based on deep belief network was built to predict severity classification criteria raised by the Global Initiative for Chronic Obstructive Lung Disease (GOLD). We get accuracy over 90% in prediction for two different standardized versions of severity criteria raised in 2007 and 2011 respectively. Moreover, we also got the contribution ranking of different input features through analyzing the model coefficient matrix and confirmed that there was a certain degree of agreement between the more contributive input features and the clinical diagnostic knowledge. The validity of the deep belief network model was proved by this result. This study provides an effective solution for the application of deep learning method in automatic diagnostic decision making.

It is important to identify patients with chronic obstructive pulmonary disease (COPD) and lung cancer in the early stages of the disease. The method of laser opto-acoustic gas analysis, in this case, can act as a promising tool for diagnostics. The material for this study were the gas emission samples collected from patients and healthy volunteers - samples of exhaled air, swabs from teeth and cheeks. A set of material was formed three groups: healthy volunteers, patients with COPD, lung cancer patients. The resulting samples were analyzed by means of laser opto-acoustic gas analyzers: with intracavity location detector (ILPA-1), with extracavity location detector (LGA-2). Presentation of the results in an easy to visual form was performed using the method of elastic maps, based on the principal component analysis. The results of analysis show potentialities of usage of laser optoacoustic spectroscopy application to assess the status of patients with chronic obstructive pulmonary disease and lung cancer.

Obstructing urethral calculus in a woman revealed to be the cause of chronic pelvic pain.

Urethral calculi are extremely rarely reported in Caucasian females and are usually associated with an anatomical abnormality such as a diverticulum or a stricture. Ureteric calculi can move to become lodged in the urethra, although this is rare in women because of their short urethral length. We present a case of a 55-year-old woman presenting with urinary retention secondary to an obstructing upper tract calculus that had moved into the urethra. Four years previously, the patient had been diagnosed with chronic pelvic pain following a primary posterior vaginal wall repair. Following treatment of the obstructing calculus, her symptoms of pelvic pain completely resolved. We report a very unusual case that highlights the importance of investigating chronic pelvic pain. This patient's symptom of vaginal pain, though highly localized, was caused by pathology elsewhere in the pelvis. Alternative diagnoses should be sought for such patients and investigation performed to detect any nonvisible hematuria.

The link between chronic periodontitis and COPD: a common role for the neutrophil?

PubMed Central

2013-01-01

Background The possible relationship between chronic inflammatory diseases and their co-morbidities has become an increasing focus of research. Both chronic periodontitis and chronic obstructive pulmonary disease are neutrophilic, inflammatory conditions characterized by the loss of local connective tissue. Evidence suggests an association and perhaps a causal link between the two diseases. However, the nature of any relationship between them is unclear, but if pathophysiologically established may have wide-reaching implications for targeted treatments to improve outcomes and prognosis. Discussion There have been a number of epidemiological studies undertaken demonstrating an independent association between chronic periodontitis and chronic obstructive pulmonary disease. However, many of them have significant limitations, and drawing firm conclusions regarding causality may be premature. Although the pathology of both these diseases is complex and involves many cell types, such as CD8 positive cells and macrophages, both conditions are predominantly characterized by neutrophilic inflammation. Increasingly, there is evidence that the two conditions are underpinned by similar pathophysiological processes, especially centered on the functions of the neutrophil. These include a disturbance in protease/anti-protease and redox state balance. The association demonstrated by epidemiological studies, as well as emerging similarities in pathogenesis at the level of the neutrophil, suggest a basis for testing the effects of treatment for one condition upon the severity of the other. Summary Although the evidence of an independent association between chronic periodontitis and chronic obstructive pulmonary disease grows stronger, there remains a lack of definitive studies designed to establish causality and treatment effects. There is a need for future research to be focused on answering these questions. PMID:24229090

Pulmonary vasculature in COPD: The silent component.

PubMed

Blanco, Isabel; Piccari, Lucilla; Barberà, Joan Albert

2016-08-01

Chronic obstructive pulmonary disease (COPD) is characterized by airflow obstruction that results from an inflammatory process affecting the airways and lung parenchyma. Despite major abnormalities taking place in bronchial and alveolar structures, changes in pulmonary vessels also represent an important component of the disease. Alterations in vessel structure are highly prevalent and abnormalities in their function impair gas exchange and may result in pulmonary hypertension (PH), an important complication of the disease associated with reduced survival and worse clinical course. The prevalence of PH is high in COPD, particularly in advanced stages, although it remains of mild to moderate severity in the majority of cases. Endothelial dysfunction, with imbalance between vasodilator/vasoconstrictive mediators, is a key determinant of changes taking place in pulmonary vasculature in COPD. Cigarette smoke products may perturb endothelial cells and play a critical role in initiating vascular changes. The concurrence of inflammation, hypoxia and emphysema further contributes to vascular damage and to the development of PH. The use of drugs that target endothelium-dependent signalling pathways, currently employed in pulmonary arterial hypertension, is discouraged in COPD due to the lack of efficacy observed in randomized clinical trials and because there is compelling evidence indicating that these drugs may worsen pulmonary gas exchange. The subgroup of patients with severe PH should be ideally managed in centres with expertise in both PH and chronic lung diseases because alterations of pulmonary vasculature might resemble those observed in pulmonary arterial hypertension. Because this condition entails poor prognosis, it warrants specialist treatment. © 2016 Asian Pacific Society of Respirology.

The purpose of this study was to determine the impact of pulmonary fibrosis (PF) on postoperative complications and on long-term survival after surgical resection in lung cancer patients with chronic obstructive pulmonary disease (COPD). A retrospective chart review was conducted of 380 patients with COPD who had undergone pulmonary resection for lung cancer at the University Hospital between 1990 and 2005. The definition of COPD was a preoperative forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) ratio of less than 70%; PF was defined as obvious bilateral fibrous change in the lower lung fields, confirmed by computed tomography. PF was present in 41 patients (10.8%) with COPD; the remaining 339 patients (89.2%) did not have PF. The preoperative FVC/FEV1 was significantly lower in the group of patients with PF than in the group without (p < 0.05). Acute lung injury and home oxygen therapy were significantly more common in the PF group; however, the 30-day mortality was similar between the groups. The cumulative survival at 3 and 5 years was 53.6 and 36.9%, respectively, in the PF group and 71.4 and 66.1%, respectively, in the non-PF group (p = 0.0009). Increased age, decreased body mass index, advanced pathologic stage, and the existence of PF were identified as independent risk factors for decreased survival. PF is a risk factor for decreased survival after surgical treatment in lung cancer patients with COPD. Georg Thieme Verlag KG Stuttgart · New York.

Chronic Cough: Evaluation and Management.

PubMed

Michaudet, Charlie; Malaty, John

2017-11-01

Although chronic cough in adults (cough lasting longer than eight weeks) can be caused by many etiologies, four conditions account for most cases: upper airway cough syndrome, gastroesophageal reflux disease/laryngopharyngeal reflux disease, asthma, and nonasthmatic eosinophilic bronchitis. Patients should be evaluated clinically (with spirometry, if indicated), and empiric treatment should be initiated. Other potential causes include angiotensin-converting enzyme inhibitor use, environmental triggers, tobacco use, chronic obstructive pulmonary disease, and obstructive sleep apnea. Chest radiography can rule out concerning infectious, inflammatory, and malignant thoracic conditions. Patients with refractory chronic cough may warrant referral to a pulmonologist or otolaryngologist in addition to a trial of gabapentin, pregabalin, and/or speech therapy. In children, cough is considered chronic if present for more than four weeks. In children six to 14 years of age, it is most commonly caused by asthma, protracted bacterial bronchitis, and upper airway cough syndrome. Evaluation should focus initially on these etiologies, with targeted treatment and monitoring for resolution.

Oender, Hakan, E-mail: drhakanonder@hotmail.com; Oguzkurt, Levent; Guer, Serkan

To evaluate the results of stent placement for obstructive atherosclerotic aortic disease with or without involvement of the common iliac artery. Forty patients had self-expanding stents primarily or after balloon dilatation in the abdominal aorta between January 2005 and May 2011. All patients had trouble walking. Follow-up examinations were performed with clinical visits; these included color Doppler ultrasonography and computed tomographic angiography. Technical, clinical, and hemodynamic success was achieved in all patients. None of the patients underwent reintervention during the follow-up period, which ranged from 3 months to 6 years (median 24 months). Nine complications occurred in six patients. Ofmore » the nine complications, four were distal thromboembolisms, which were successfully treated with catheter-directed thrombolysis or anticoagulation therapy. Endovascular treatment of the obstructive aortic disease using self-expanding stents was safe and effective, with high technical success and long-term patency. Thromboembolic complications were high even though direct stenting was considered protective for thromboembolism formation. Particularly for infrarenal aortic stenosis, it can be recommended as the first-line treatment option for patients with obstructive atherosclerotic aortic disease.« less

Both brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index (ABI) are important predictors for cardiovascular disease (CVD). Patients with chronic obstructive pulmonary disease (COPD) are at high risk of CVD. But the association between airflow obstruction and baPWV or ABI was still unclear. The study was aimed to investigate the influencing factors on arterial stiffness in aged COPD patients. 67 aged patients with COPD and 67 age- and sex-matched controls without COPD were enrolled in this study. COPD patients were grouped into four groups according to the Global Initiative for Chronic Obstructive Lung Disease Guidelines (GOLD). Both baPWV and ABI were evaluated. Spirometry indices, blood pressure, smoking history and related laboratory parameters were also collected. Comparing with controls, all COPD patients had significantly higher baPWV (1933 ± 355 cm/s versus 1515 ± 256 cm/s, P < 0.001) but not ABI (P = 0.196). And baPWV values were significantly highest at GOLD stage 4. Forced expiratory volume in 1 s (FEV1) was the most significant factor influencing baPWV, after adjusting for age, systolic blood pressure and other traditional cardiovascular risk factors (β = -0.463, P = 0.014). Arterial stiffness was serious in aged patients with COPD. Spirometry index FEV1 was a possible important predictor for the severity of arterial stiffness of COPD patients.

To evaluate the applicability of the incremental (shuttle) walk test in patients with chronic obstructive pulmonary disease and compare the performance of those patients on the shuttle walk test to that of the same patients on the encouraged 6-minute walk test. A cross-sectional study was conducted, in which 24 patients with chronic obstructive pulmonary disease were selected. In random order, patients were, after an initial practice period, submitted to a shuttle walk test and an encouraged 6-minute walk test. The patients obtained a higher heart rate (expressed as a percentage of that predicted based on gender and age) on the encouraged 6-minute walk test (84.1 +/- 11.4%) than on the shuttle walk test (76.4 +/- 9.7%) (p = 0.003). The post-test sensation of dyspnea (Borg scale) was also higher on the encouraged 6-minute walk test. On average, the patients walked 307.0 +/- 89.3 meters on the shuttle walk test and 515.5 +/- 102.3 meters on the encouraged 6-minute walk test (p < 0.001). There was a good correlation between the two tests in terms of the distance walked (r = 0.80, p < 0.001). The shuttle walk test is simple and easy to implement in patients with chronic obstructive pulmonary disease. The encouraged 6-minute walk test produced higher post-test heart rate and greater post-test sensation of dyspnea than did the shuttle walk test.

The majority of swallowed foreign bodies are thrown spontaneously without causing complications in the digestive system. Multiple number of foreign bodies may be swallowed by psychiatric patients which delay diagnosis and increase the complication rate. Long and hard objects cannot pass through the pylorus, and may cause obstruction, ulceration, bleeding and perforation. Endoscopy is used as an effective method in such cases. An exploratory laparatomy was performed after unsuccessful endoscopic foreign object removal in a 28-year-old schizophrenic patient with gastric outlet obstruction due to multiple cigarette lighter swallowing. Ten lighters were removed from the stomach through gastrotomy and one more lighter was removed from the descending colon by milking through the anus. The aim of this paper is to discuss encountered difficulties in psychiatric patients who underwent surgery due to intake of foreign bodies.

Chronic obstructive pulmonary disease (COPD) is a chronic, progressive disease, and reversal of COPD diagnosis is thought to be uncommon. To determine whether a spirometric diagnosis of mild or moderate COPD is subject to variability and potential error. We examined two prospective cohort studies that enrolled subjects with mild to moderate post-bronchodilator airflow obstruction. The Lung Health Study (n = 5,861 subjects; study duration, 5 yr) and the Canadian Cohort of Obstructive Lung Disease (CanCOLD) study (n = 1,551 subjects; study duration, 4 yr) were examined to determine frequencies of (1) diagnostic instability, represented by how often patients initially met criteria for a spirometric diagnosis of COPD but then crossed the diagnostic threshold to normal and then crossed back to COPD over a series of annual visits, or vice versa; and (2) diagnostic reversals, defined as how often an individual's COPD diagnosis at the study outset reversed to normal by the end of the study. Diagnostic instability was common and occurred in 19.5% of the Lung Health Study subjects and 6.4% of the CanCOLD subjects. Diagnostic reversals of COPD from the beginning to the end of the study period occurred in 12.6% and 27.2% of subjects in the Lung Health Study and CanCOLD study, respectively. The risk of diagnostic instability was greatest for subjects whose baseline FEV 1 /FVC value was closest to the diagnostic threshold, and the risk of diagnostic reversal was greatest for subjects who quit smoking during the study. A single post-bronchodilator spirometric assessment may not be reliable for diagnosing COPD in patients with mild to moderate airflow obstruction at baseline.

This study aims to compare the clinical outcomes and costs between percutaneous transhepatic biliary stenting (PTBS) and surgical bypass. We randomly assigned 142 patients with unresectable malignant biliary obstruction between 2005 and 2010 to receive PTBS or surgical bypass as palliative treatment. PTBS was successfully performed in 70 patients who formed the PTBS group (failed in 7 patients). Sixty five patients underwent surgical bypass treatment. Additional gastrojejunostomy was performed in five patients. The effectiveness of biliary drainage, hospital stay, complications, cost, survival time and mortality were compared. Patients in PTBS group had shorter hospital stay and lower initial and overall expense than the surgical group (p<0.05). There was no significant difference in effectiveness of biliary drainage (p=0.9307) or survival time between two groups (p=0.4826). Early complications of PTBS group was significantly lower than surgical group (3/75 vs. 11/65, p=0.0342). Late complication in PTBS group did not differ significantly from surgical group (9/70 vs. 6/65, p=0.6823). The survival curves in the two groups showed no significant difference (p=0.1032). PTBD is a better palliative treatment than surgical bypass for unresectable malignant biliary obstruction for its high effectiveness of biliary drainage and acceptable expense and complication.

This review will discuss the immediate- and long-term success, complications and overall benefits of self-expandable metal stents (SEMSs) in malignant or benign obstruction of the oesophagus, stomach and duodenum. Over recent years, indications such as benign disease have expanded, as has SEMS diversity with self-expandable plastic stents (SEPSs) or fully covered and biodegradable stents, for example. SEMSs have been increasingly used in malignant upper gastrointestinal obstruction with many reports confirming efficacy, despite a significant complication rate. Fully covered stents are increasingly used for a variety of benign oesophageal disease, but their place in gastric outlet obstruction is still unclear. Covered and uncovered stents have different functional characteristics and stent type must be selected on an individual basis. Biodegradable stents show promise and the outcome of experience in larger patient cohorts is eagerly awaited. This area is an evolving field, in which the clinician requires up-to-date knowledge of therapeutic options to make individualized treatment choices in difficult clinical circumstances. Technical and clinical success for oesophageal or gastroduodenal SEMSs are then above 90%. Minor complications are common, but serious complications seldom occur. Biodegradable stents may be useful, especially when stenting is needed for a short period of time.

The aim of this study was to assess the treatment patterns and 3 to 12-month complication rates associated with receiving prostate cryotherapy in a population-based study. Men > 65 years diagnosed with incident localized prostate cancer in Surveillance Epidemiology End Results (SEER) - Medicare linked database from 2004 to 2005 were identified. A total of 21,344 men were included in the study, of which 380 were treated initially with cryotherapy. Recipients of cryotherapy versus aggressive forms of prostate therapy (i.e. radical prostatectomy or radiation therapy) were more likely to be older, have one co-morbidity, low income, live in the South, and be diagnosed with indolent cancer. Complication rates increased from 3 to 12 months following cryotherapy. By the twelfth month, the rates for urinary incontinence, lower urinary tract obstruction, erectile dysfunction, and bowel bleeding reached 9.8%, 28.7%, 20.1%, and 3.3%, respectively. Diagnoses of hydronephrosis, urinary fistula, or bowel fistula were not evident. The rates of corrective invasive procedures for lower urinary tract obstruction and erectile dysfunction were both <2.9% by the twelfth month. Overall, complications post cryotherapy were modest; however, diagnoses for lower urinary tract obstruction and erectile dysfunction were common. PMID:21519347

Malignant biliary obstruction is commonly caused by gall bladder carcinoma, cholangiocarcinoma and metastatic nodes. Percutaneous interventions play an important role in managing these patients. Biliary drainage, which forms the major bulk of radiological interventions, can be palliative in inoperable patients or pre-operative to improve liver function prior to surgery. Other interventions include cholecystostomy and radiofrequency ablation. We present here the indications, contraindications, technique and complications of the radiological interventions performed in patients with malignant biliary obstruction. PMID:27247718

2017-02-01

To describe a novel surgical technique for the correction of recurrent obstructive urolithiasis in male goats. Clinical case series. Castrated male goats (n = 4). Medical records of male goats having undergone vesicopreputial anastomosis (VPA) as a treatment for obstructive urolithiasis were reviewed for history, signalment, clinical signs, and intraoperative and postoperative complications. Long-term follow-up (≥12 months) was obtained by telephone interview with owners or by clinical examination. All goats had undergone at least one surgical procedure (median, 2.5, range 2-4) to correct obstructive urolithiasis before undergoing VPA. Postoperative complications included premature removal of the tube from the bladder (1 goat), bacterial cystitis (2), and abscess formation (1). One goat suffered stricture of the anastomosis site 3 months following the original procedure and underwent a second VPA and 1 goat died 7 months after surgery due to severe, acute hydronephrosis and renal failure. Long-term survival ≥12 months was good with 3/4 goats (75%) or 3/5 VPA procedures (60%) having unobstructed urine flow at 12 months. Vesicopreputial anastomosis is a feasible surgical procedure for the correction of recurrent obstructive urolithiasis in male goats and one that can result in a favorable clinical outcome. Further investigation in a larger population of goats is warranted for the evaluation of the suitability of VPA in male goats with obstructive urolithiasis. © 2017 The American College of Veterinary Surgeons.

Objective To evaluate the efficacy of methylene blue in preventing recurrent symptomatic postoperative adhesions. Methods Patients with a history of >2 surgeries for intra-abdominal adhesion-related complications were selected for this study. Adhesiolysis surgery was subsequently performed using administration of 1% methylene blue. The follow-up period was 28.5 ± 11.1 months. Results Data were available from 20 patients (seven men and 13 women) whose mean ± SD age was 51.2 ± 11.4 years. Adhesions took longer to become symptomatic after the first abdominal surgery when the initial pathology was malignant compared with benign. However, the recurrence of adhesions after a previous adhesiolysis surgery had a similar time onset regardless of the initial disease. Following adhesiolysis surgery with methylene blue, the majority of patients did not present with symptoms associated with adhesion complications (i.e., chronic abdominal pain, bowel obstruction) for the length of the follow-up period. Conclusions The use of methylene blue during adhesiolysis surgery appears to reduce the recurrence of adhesion-related symptoms, suggesting a beneficial effect in the prevention of adhesion formation.

Long-term respiratory health effects in textile workers.

Over 60 million people worldwide work in the textile or clothing industry. Recent studies have recognized the contribution of workplace exposures to chronic lung diseases, in particular chronic obstructive pulmonary disease (COPD). Early studies in textile workers have focused on the relationship between hemp or cotton dust exposure and the development of a syndrome termed byssinosis. The purpose of this review is to evaluate the effect of long-term exposure to organic dust in textile workers on chronic respiratory disease in the broader context of disease classifications, such as reversible or irreversible obstructive lung disease (i.e. asthma or COPD), and restrictive lung disease. Cessation of exposure to cotton dust leads to improvement in lung function. Recent animal models have suggested a shift in the lung macrophage:dendritic cell population ratio as a potential mechanistic explanation for persistent inflammation in the lung due to repeated cotton dust-related endotoxin exposure. Other types of textile dust, such as silk, may contribute to COPD in textile workers. Textile dust-related obstructive lung disease has characteristics of both asthma and COPD. Significant progress has been made in the understanding of chronic lung disease due to organic dust exposure in textile workers.

Chronic idiopathic intestinal pseudo-obstruction treated by near total small bowel resection: a 20-year experience.

Patients suffering from chronic idiopathic intestinal pseudo-obstruction (CIIPO) clearly benefit from home parenteral nutrition (HPN) to maintain adequate nutritional status and general health. But intestinal dismotility can seriously disturb their quality of life (QOL) to the point of making it intolerable. Report our clinical experience on the management of chronic severe occlusive symptoms in CIIPO by near total small bowel resection. A 20-year retrospective study of eight patients with end-stage CIIPO maintained on HPN and suffering of chronic occlusive symptoms refractory to medical treatment underwent extensive small bowel resection preserving less than 70 cm of total small bowel and less than 20 cm of ileum. The jejunum was anastomosed either to the ileum or to the colon. Six patients were completely relieved from obstructive symptoms. Two patients needed a second operation to remove the residual ileum because of recurrent symptoms. Two were significantly improved. There was no post-operative death. All patients experienced a significant improvement in their QOL. Near total small bowel resection appears to be a safe and effective procedure in end-stage CIIPO patients, refractory to optimal medical treatment.

Role of the inflammasome in chronic obstructive pulmonary disease (COPD)

2017-01-01

Inflammation is central to the development of chronic obstructive pulmonary disease (COPD), a pulmonary disorder characterized by chronic bronchitis, chronic airway obstruction, emphysema, associated to progressive and irreversible decline of lung function. Emerging genetic and pharmacological evidence suggests that IL-1-like cytokines are highly detected in the sputum and broncho-alveolar lavage (BAL) of COPD patients, implying the involvement of the multiprotein complex inflammasome. So far, scientific evidence has focused on nucleotide-binding oligomerization domain-like receptors protein 3 (NLRP3) inflammasome, a specialized inflammatory signaling platform that governs the maturation and secretion of IL-1-like cytokines through the regulation of caspase-1-dependent proteolytic processing. Some studies revealed that it is involved during airway inflammation typical of COPD. Based on the influence of cigarette smoke in various respiratory diseases, including COPD, in this view we report its effects in inflammatory and immune responses in COPD mouse models and in human subjects affected by COPD. In sharp contrast to what reported on experimental and clinical studies, randomized clinical trials show that indirect inflammasome inhibitors did not have any beneficial effect in moderate to severe COPD patients.

Long-Term Oxygen Therapy for Patients With Chronic Obstructive Pulmonary Disease (COPD)

PubMed Central

2012-01-01

Executive Summary In July 2010, the Medical Advisory Secretariat (MAS) began work on a Chronic Obstructive Pulmonary Disease (COPD) evidentiary framework, an evidence-based review of the literature surrounding treatment strategies for patients with COPD. This project emerged from a request by the Health System Strategy Division of the Ministry of Health and Long-Term Care that MAS provide them with an evidentiary platform on the effectiveness and cost-effectiveness of COPD interventions. After an initial review of health technology assessments and systematic reviews of COPD literature, and consultation with experts, MAS identified the following topics for analysis: vaccinations (influenza and pneumococcal), smoking cessation, multidisciplinary care, pulmonary rehabilitation, long-term oxygen therapy, noninvasive positive pressure ventilation for acute and chronic respiratory failure, hospital-at-home for acute exacerbations of COPD, and telehealth (including telemonitoring and telephone support). Evidence-based analyses were prepared for each of these topics. For each technology, an economic analysis was also completed where appropriate. In addition, a review of the qualitative literature on patient, caregiver, and provider perspectives on living and dying with COPD was conducted, as were reviews of the qualitative literature on each of the technologies included in these analyses. The Chronic Obstructive Pulmonary Disease Mega-Analysis series is made up of the following reports, which can be publicly accessed at the MAS website at: http://www.hqontario.ca/en/mas/mas_ohtas_mn.html.

The Toronto Health Economics and Technology Assessment (THETA) collaborative has produced an associated report on patient preference for mechanical ventilation. For more information, please visit the THETA website: http://theta.utoronto.ca/static/contact. Objective The objective of this health technology assessment was to determine the effectiveness, cost-effectiveness, and safety of long-term oxygen therapy (LTOT) for chronic obstructive pulmonary disease (COPD). Clinical Need: Condition and Target Population Oxygen therapy is used in patients with COPD with hypoxemia, or very low blood oxygen levels, because they may have difficulty obtaining sufficient oxygen from inspired air. Technology Long-term oxygen therapy is extended use of oxygen. Oxygen therapy is delivered as a gas from an oxygen source. Different oxygen sources are: 1) oxygen concentrators, electrical units delivering oxygen converted from room air; 2) liquid oxygen systems, which deliver gaseous oxygen stored as liquid in a tank; and 3) oxygen cylinders, which contain compressed gaseous oxygen. All are available in portable versions. Oxygen is breathed in through a nasal cannula or through a mask covering the mouth and nose. The treating clinician determines the flow rate, duration of use, method of administration, and oxygen source according to individual patient needs. Two landmark randomized controlled trials (RCTs) of patients with COPD established the role of LTOT in COPD. Questions regarding the use of LTOT, however, still remain. Research Question What is the effectiveness, cost-effectiveness, and safety of LTOT compared with no LTOT in patients with COPD, who are stratified by severity of hypoxemia? Research Methods Literature Search Search Strategy A literature search was performed on September 8, 2010 using OVID MEDLINE, MEDLINE In-Process and Other Non-Indexed Citations, EMBASE, CINAHL, the Cochrane Library, and INAHTA for studies published from January 1, 2007 to September 8, 2010. A single clinical epidemiologist reviewed the abstracts, obtained full-text articles for studies meeting the eligibility criteria, and examined reference lists for additional relevant studies not identified through the literature search. A second clinical epidemiologist and then a group of epidemiologists reviewed articles with an unknown eligibility until consensus was established. Inclusion Criteria patients with mild, moderate, or severe hypoxemia; English-language articles published between January 1, 2007 and September 8, 2010; journal articles reporting on effectiveness, cost-effectiveness, or safety for the comparison of interest; clearly described study design and methods; health technology assessments, systematic reviews, RCTs, or prospective cohort observational studies; any type of observational study for the evaluation of safety. Exclusion Criteria no hypoxemia non-English papers animal or in vitro studies case reports, case series, or case-case studies studies comparing different oxygen therapy regimens studies on nocturnal oxygen therapy studies on short-burst, palliative, or ambulatory oxygen (supplemental oxygen during exercise or activities of daily living) Outcomes of Interest mortality/survival hospitalizations readmissions forced expiratory volume in 1 second (FEV1) forced vital capacity (FVC) FEV1/FVC pulmonary hypertension arterial partial pressure of oxygen (PaO2) arterial partial pressure of carbon dioxide (PaCO2) end-exercise dyspnea score endurance time health-related quality of life Note: Outcomes of interest were formulated according to existing studies, with arterial pressure of oxygen and carbon dioxide as surrogate outcomes. Summary of Findings Conclusions Based on low quality of evidence, LTOT (~ 15 hours/day) decreases all-cause mortality in patients with COPD who have severe hypoxemia (PaO2 ~ 50 mm Hg) and heart failure. The effect for all-cause mortality had borderline statistical significance when the control group was no LTOT: one study. Based on low quality of evidence, there is no beneficial effect of LTOT on all-cause mortality at 3 and 7 years in patients with COPD who have mild-to-moderate hypoxemia (PaO2 ~ 59-65 mm Hg)1 Based on very low quality of evidence, there is some suggestion that LTOT may have a beneficial effect over time on FEV1 and PaCO2 in patients with COPD who have severe hypoxemia and heart failure: improved methods are needed. Based on very low quality of evidence, there is no beneficial effect of LTOT on lung function or exercise factors in patients with COPD who have mild-to-moderate hypoxemia, whether survivors or nonsurvivors are assessed. Based on low to very low quality of evidence, LTOT does not prevent readmissions in patients with COPD who have severe hypoxemia. Limited data suggest LTOT increases the risk of hospitalizations. Limited work has been performed evaluating the safety of LTOT by severity of hypoxemia. Based on low to very low quality of evidence, LTOT may have a beneficial effect over time on health-related quality of life in patients with COPD who have severe hypoxemia. Limited work using disease-specific instruments has been performed. Ethical constraints of not providing LTOT to eligible patients with COPD prohibit future studies from examining LTOT outcomes in an ideal way. PMID:23074435

We report the case of a 71-year-old woman with end-stage chronic obstructive pulmonary disease who presented with a 10-cm tracheal laceration from a presumed traumatic intubation in the setting of respiratory distress and chronic obstructive pulmonary disease exacerbation and subsequently developed significant subcutaneous emphysema along her neck and mediastinum in addition to her peritoneum and mesentery. We were successfully able to treat this patient conservatively up until the time that tracheostomy was warranted. We discuss and review tracheobronchial injuries with respect to etiology, risk factors, and management and hope to benefit health care providers managing airways in patients at risk for tracheal injury.

Smoking cessation is the only effective intervention to slow down the accelerated decline in lung function in smokers with chronic obstructive pulmonary disease. Nevertheless, physicians often do not routinely provide evidence-based smoking cessation treatment to their patients. To understand underlying reasons, we explored how physicians engage in smoking cessation treatment in their chronic obstructive pulmonary disease patients. In total, 21 focus group discussions were held with general practitioners and pulmonologists in seven different countries in Europe and Asia. We generated three themes, whereby some of the issues concerned smokers in general: first, 'physicians' frustration with chronic obstructive pulmonary disease patients who smoke'. These frustrations interfered with the provision of evidence-based treatment and could result in this group of patients being treated unequally. Second: 'physicians' limited knowledge of, and negative beliefs about, smoking cessation treatment'. This hindered treating smokers effectively. Third: 'healthcare organisational factors that influence the use of smoking cessation treatments'. Money and time issues, as well as the failure to regard smoking as a disease, influenced how physicians engaged in smoking cessation treatment. Our results indicate that there is a number of barriers to the provision of effective smoking cessation treatment in patients with chronic obstructive pulmonary disease and smokers in general. Introducing an informative smoking cessation programme, including communication skills and ethical issues, in the vocational and postgraduate medical training may help to address these barriers. This is important in order to increase engagement with smoking cessation treatment and to improve quality of chronic obstructive pulmonary disease care. CHANGING ATTITUDES TO HELP PATIENTS STOP SMOKING: Doctors should be given careful, ethically-informed guidance during medical training to help them to support patients to quit smoking. The most important part of treatment for patients with chronic obstructive pulmonary disease (COPD) is help to stop smoking. However, there is evidence to suggest that doctors don't always motivate COPD patients to quit. Eva Anne Marije van Eerd at Maastrict University, The Netherlands, together with an international team of scientists, conducted focus group interviews with doctors in seven different countries to assess barriers to smoking cessation. They found that doctors' frustration with and negative attitudes towards patients who continued to smoke contributed to poor cessation management and treatment inequalities in some cases. Many doctors also cited a lack of experience with smoking cessation techniques alongside time and money issues as barriers to effective treatment.

Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent chronic obstructive lung diseases with an associated high burden of disease. Asthma, which is often allergic in origin, frequently begins in infancy or childhood with variable airflow obstruction and intermittent wheezing, cough, and dyspnea. Patients with COPD, in contrast, are usually current or former smokers who present after the age of 40 years with symptoms (often persistent) including dyspnea and a productive cough. On the basis of age and smoking history, it is often easy to distinguish between asthma and COPD. However, some patients have features compatible with both diseases. Because clinical studies typically exclude these patients, their underlying disease mechanisms and appropriate treatment remain largely uncertain. To explore the status of and opportunities for research in this area, the NHLBI, in partnership with the American Thoracic Society, convened a workshop of investigators in San Francisco, California on May 14, 2016. At the workshop, current understanding of asthma-COPD overlap was discussed among clinicians, pathologists, radiologists, epidemiologists, and investigators with expertise in asthma and COPD. They considered knowledge gaps in our understanding of asthma-COPD overlap and identified strategies and research priorities that will advance its understanding. This report summarizes those discussions.

Dyssynchronous breathing during arm but not leg exercise in patients with chronic airflow obstruction.

PubMed

Celli, B R; Rassulo, J; Make, B J

1986-06-05

Some patients with chronic airflow obstruction experience dyspnea with mild arm exercise but not with more-intense leg exercise. To investigate why these patients have limited endurance during arm exertion, we studied ventilatory responses to exercise with unsupported arms in 12 patients with chronic airflow obstruction (mean [+/- SD] forced expiratory volume in one second, 0.68 +/- 0.28 liters). Unloaded leg cycling was also studied for comparison. In the five patients who had the most severe airflow obstruction, arm exercise was limited by dyspnea after 3.3 +/- 0.7 minutes, and dyssynchronous thoracoabdominal breathing developed. In the other seven patients, arm exercise was limited by the sensation of muscle fatigue after 6.1 +/- 2.0 minutes (P less than 0.05), and dyssynchronous breathing did not occur. None of the 12 patients had dyssynchronous breathing during unloaded leg cycling. Maximal transdiaphragmatic pressure, a measure of diaphragmatic fatigue, declined similarly after arm and leg exercise in both groups. During unsupported arm work, the accessory muscles of inspiration help position the torso and arms. We hypothesize that the extra demand placed on these muscles during arm exertion leads to early fatigue, an increased load on the diaphragm, and dyssynchronous thoracoabdominal inspirations. This sequence may contribute to dyspnea and limited endurance during upper-extremity exercise.

Urgent surgery for complicated colonic diverticula.

Funariu, Gheorghe; Binţinţan, Vasile; Seicean, Radu

2006-03-01

The AIM of this retrospective study was to evaluate the emergency surgical treatment of life-threatening complications of colonic diverticula. In the last 11 years, 22 of 101 patients with colonic diverticula (22.1%) underwent urgent surgery for acute complications: perforated gangrenous diverticulitis with generalized peritonitis (n=8) or pericolic abscess (n=8), acute bowel obstruction (n=4) and severe diverticular bleeding (n=2). In all patients with diffuse peritonitis or acute obstruction the indication for surgery was decided on clinical basis and the complicated diverticula were recognized only intra-operatively. Emergency surgical strategy differed according to the type of complication and the biologic condition of the patient: segmental colectomy and primary anastomosis for diverticular perforation (n=4), colonic stenosis (n=3) or diverticular bleeding (n=2); Hartmann resection with late reconnecting anastomosis in patients with diverticular perforation (n=5) or colonic obstruction (n=1); diverticulectomy with peritoneal drainage (n=2) and colostomy and drainage followed by secondary colectomy (n=5) for diverticular perforations in patients with poor general condition. Only one patient (4.5%) died post-operatively of multiple organ failure from generalized peritonitis. There was no anastomotic leakage in patients with primary anastomosis. Six patients (27.2%) developed wound infection. Hospital stay ranged between 11 and 60 days, significantly longer in cases with two-stage operations. Primary colectomy with immediate or delayed anastomosis is the best surgical procedure for acute divericular complications in patients with good biologic status. Two-stage operations such as colostomy and drainage coupled with late colectomy remain the viable alternative in patients with advanced disease and critical biologic condition.

The objective of this study was to analyze three ureteral stenting techniques in patients with malignant ureteral obstructions, considering the indications, techniques, procedural costs, and complications. In the period between June 2003 and June 2006, 45 patients with bilateral malignant ureteral obstructions were evaluated (24 males, 21 females; average age, 68.3; range, 42-87). All of the patients were treated with ureteral stenting: 30 (mild strictures) with direct stenting (insertion of the stent without predilation), 30 (moderate/severe strictures) with primary stenting (insertion of the stent after predilation in a one-stage procedure), and 30 (mild/moderate/severe strictures with infection) with secondary stenting (insertionmore » of the stent after predilation and 2-3 days after nephrostomy). The incidence of complications and procedural costs were compared by a statistical analysis. The primary technical success rate was 98.89%. We did not observe any major complications. The minor complication rate was 11.1%. The incidence of complications for the various techniques was not statistically significantly. The statistical analysis of costs demonstrated that the average cost of secondary stenting ( Euro 637; SD, Euro 115) was significantly higher than that of procedures which involved direct or primary stenting ( Euro 560; SD, Euro 108). We conclude that one-step stenting (direct or primary) is a valid option to secondary stenting in correctly selected patients, owing to the fact that when the procedure is performed by expert interventional radiologists there are high technical success rates, low complication rates, and a reduction in costs.« less

CLCA1 and TMEM16A: the link towards a potential cure for airway diseases.

The hallmark traits of chronic obstructive airway diseases are inflammation, airway constriction due to hyperreactivity and mucus overproduction. The current common treatments for asthma and chronic obstructive pulmonary disease target the first two traits with none currently targeting mucus overproduction. The main source of obstructive mucus production is mucus cell metaplasia (MCM), the transdifferentiation of airway epithelial cells into mucus-producing goblet cells, in the small airways. Our current understanding of MCM is profusely incomplete. Few of the molecular players involved in driving MCM in humans have been identified and for many of those that have, their functions and mechanisms are unknown. This fact has limited the development of therapeutics that target mucus overproduction by inhibiting MCM. Current work in the field is aiming to change that.

NONE DECLARED. P-wave abnormalities on the resting electrocardiogram have been associated with cardiovascular or pulmonary disease. So far, "Gothic" P wave and verticalization of the frontal plane axis is related to lung disease, particularly obstructive lung disease. We tested if inverted P wave in AVl as a lone criteria of P wave axis >70° could be screening tool for emphysema. 1095 routine electrocardiograms (ECGs) were reviewed which yielded 478 (82,1%) ECGs with vertical P-axis in sinus rhythm. Charts were reviewed for the diagnosis of COPD and emphysema based on medical history and pulmonary function tests. Electrocardiogram is very effective screening tool not only in cardiovascular field but in chronic obstructive pulmonary disease. The verticality of the P axis is usually immediately apparent, making electrocardiogram rapid screening test for emphysema.

Chronic obstructive pulmonary disease (COPD) is a lung disease characterized by airway obstruction and inflammation but also accompanied by several extrapulmonary consequences, such as skeletal muscle weakness and osteoporosis. Skeletal muscle weakness is of major concern, since it leads to poor functional capacity, impaired health status, increased healthcare utilization, and even mortality, independently of lung function. Osteoporosis leads to fractures and is associated with increased mortality, functional decline, loss of quality of life, and need for institutionalization. Therefore, the presence of the combination of these comorbidities will have a negative impact on daily life in patients with COPD. In this review, we will focus on these two comorbidities, their prevalence in COPD, combined risk factors, and pathogenesis. We will try to prove the clustering of these comorbidities and discuss possible preventive or therapeutic strategies. PMID:24783225

To understand recent temporal trends in acquired immunodeficiency syndrome (AIDS) mortality in the era of highly active antiretroviral therapy (HAART), trends in causes of death among persons with AIDS in San Francisco who died between 1994 and 1998 were analyzed. Among 5234 deaths, the mortality rate for human immunodeficiency virus (HIV)-related or AIDS-related deaths declined after 1995 (P<.01), whereas the mortality rate for non-HIV- or non-AIDS-related deaths remained stable. The proportion of deaths of persons with AIDS associated with septicemia, non-AIDS-defining malignancy, chronic liver disease, viral hepatitis, overdose, obstructive lung disease, coronary artery disease, and pancreatitis increased (P<.05). The standardized mortality ratio was high for these causes in both pre- and post-HAART periods, except for pancreatitis, a possible complication of HAART, which demonstrated an increasing standardized mortality ratio trend after 1996. With increasing AIDS survival, prevention of chronic diseases, assessment of long-term toxicity from HAART, and surveillance for additional causes of mortality will become increasingly important.

Alternative payment models in total joint replacement incentivize cost effective health care delivery and reward reductions in length of stay (LOS), complications, and readmissions. If not adjusted for patient comorbidities, they may encourage restrictive access to health care. We prospectively evaluated 802 consecutive primary total hip arthroplasty and total knee arthroplasty patients evaluating comorbidities associated with increased LOS and readmissions. During this 9-month period, 115 patients (14.3%) required hospitalization >3 days and 16 (1.99%) were readmitted within 90 days. Univariate analysis demonstrated that preoperative narcotic use, heart failure, stroke, chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), and liver disease were more likely to require hospitalization >3 days. In multivariate analysis, CKD and COPD were independent risk factors for LOS >3 days. A Charlson comorbidity index >5 points was associated with increased LOS and readmissions. Patients with CKD, COPD, and Charlson comorbidity index >5 points should not be included in alternative payment model for THA and TKA. Copyright © 2016 Elsevier Inc. All rights reserved.

Recently, pulmonary rehabilitation program is widely considered one of the most effective and evidence-based treatment for not only chronic obstructive pulmonary disease (COPD) but many clinical situations including neuro-muscular disease, post-operative status and weaning period from the ventilator, etc. The essential components of a pulmonary rehabilitation program are team assessment, patient training, psycho-social intervention, exercise, and follow-up. In 2003, Japanese medical societies (J. Thoracic Society, J. Pul. Rehabilitation Society and J. Physiotherapist Society) made a new guideline for pulmonary rehabilitation, especially how to aproach the execise training. As for the duration after surgical operation, airway cleaning is the important technique to prevent post-operative complications including pneumonia. Postural dranage technique is well known for such condition, at the same time, several instruments (flutter vulve, positive expiratory mask, high frequecy oscillation, etc) were also used for the patient to expectrate airway mucus easier. Lung transplantation is a new method of treatment for the critically-ill patients with chronic respiratoy failure. Several techniques of physical therapy are must be needed before and after lung transplantation to prevent both pulmonary infection and osteoporosis.

Interaction between Chronic Obstructive Pulmonary Disease (COPD) and other important health conditions and measurable air pollution

Adverse health effects have been associated with urban pollutant exposure arising from close proximity to highly-emitting sources and atmospheric mixing. The relative air pollution exposure dose and time effects on various diseases remains unknown. This study compares the increased risk of health complications when patients are exposed to short term high-levels of air pollution vs. longer term exposure to lower levels of air pollution. We used the electronic medical record of an integrated hospital system based in Utah, Intermountain Healthcare, to identify a cohort of patients with Chronic Obstructive Pulmonary Disease (COPD) who were seen between 2009-2014. We determined patient demographics as well as comorbidity data and healthcare utilization. To determine the approximate air pollution dose and time exposure, we used the Hestia highly-resolved emissions inventory for Salt Lake County, Utah in conjunction with emissions based on the National Emissions Inventory (NEI). Hourly emissions of CO2 and criteria air pollutants were gridded at a 0.002o x 0.002o resolution for the study years. The resulting emissions were transported using the CALPUFF and AERMOD dispersion models to estimate air pollutant concentrations at an hourly 0.002o x 0.002oresolution. Additionally, pollutant concentrations were estimated at each patient's home and work address to estimate exposure. Multivariate analysis adjusting for patient demographics, comorbidities and severity of COPD was performed to determine association between air pollution exposure and the risk of hospitalization or emergency department (ED) visit for COPD exacerbation and an equivalency estimate for air pollution exposure was developed. We noted associations with air pollution levels for each pollutant and hospitalizations and ED visits for COPD and other patient comorbidities. We also present an equivalency estimate for dose of air pollution exposure and health outcomes. This analysis compares the increased risk of health complications when patients are exposed to short term high-levels of air pollution vs. longer term exposure to lower levels of air pollution. These findings highlight pollutant emissions and exposures spatial and temporal heterogeneity and associated health effects.

Chronic obstructive pulmonary disease (COPD) is a commonly reported cause of death and associated with smoking. However, COPD mortality is high in poor countries with low smoking rates. Spirometric restriction predicts mortality better than airflow obstruction, suggesting that the prevalence of restriction could explain mortality rates attributed to COPD. We have studied associations between mortality from COPD and low lung function, and between both lung function and death rates and cigarette consumption and gross national income per capita (GNI). National COPD mortality rates were regressed against the prevalence of airflow obstruction and spirometric restriction in 22 Burden of Obstructive Lung Disease (BOLD) study sites and against GNI, and national smoking prevalence. The prevalence of airflow obstruction and spirometric restriction in the BOLD sites were regressed against GNI and mean pack years smoked. National COPD mortality rates were more strongly associated with spirometric restriction in the BOLD sites (<60 years: men rs=0.73, p=0.0001; women rs=0.90, p<0.0001; 60+ years: men rs=0.63, p=0.0022; women rs=0.37, p=0.1) than obstruction (<60 years: men rs=0.28, p=0.20; women rs=0.17, p<0.46; 60+ years: men rs=0.28, p=0.23; women rs=0.22, p=0.33). Obstruction increased with mean pack years smoked, but COPD mortality fell with increased cigarette consumption and rose rapidly as GNI fell below US$15 000. Prevalence of restriction was not associated with smoking but also increased rapidly as GNI fell below US$15 000. Smoking remains the single most important cause of obstruction but a high prevalence of restriction associated with poverty could explain the high 'COPD' mortality in poor countries.

Purpose Mesenchymal stem cells (MSCs) hold promise for the treatment of renal disease. While MSCs have been shown to accelerate recovery and prevent acute renal failure in multiple disease models, the effect of MSC therapy on chronic obstruction-induced renal fibrosis has not previously been evaluated. Materials and Methods Male Sprague-Dawley rats underwent renal artery injection of vehicle or fluorescent-labeled human bone marrow-derived MSCs immediately prior to sham operation or induction of left ureteral obstruction (UUO). One or 4 weeks later, the kidneys were harvested and the renal cortex analyzed for evidence of stem cell infiltration, epithelial-mesenchymal transition (EMT) as evidenced by E-cadherin/α-smooth muscle actin (α-SMA) expression and fibroblast specific protein (FSP+) staining, renal fibrosis (collagen content, Masson’s trichrome staining), and cytokine and growth factor activity (ELISA and real time RT-PCR). Results Fluorescent-labeled MSCs were detected in the interstitium of the kidney up to 4 weeks post-obstruction. Arterially delivered MSCs significantly reduced obstruction-induced α-SMA expression, FSP+ cell accumulation, total collagen content, and tubulointerstitial fibrosis, while simultaneously preserving E-cadherin expression, suggesting that MSCs prevent obstruction-induced EMT and renal fibrosis. Exogenous MSCs reduced obstruction-induced tumor necrosis factor-α (TNF-α) levels, but did not alter transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF), interleukin-10 (IL-10), fibroblast growth factor (FGF), or hepatocyte growth factor (HGF) expression. Conclusions Human bone marrow-derived MSCs remain viable several weeks after delivery into the kidney and provide protection against obstruction-induced EMT and chronic renal fibrosis. While the mechanism of MSCs-induced renal protection during obstruction remains unclear, our results demonstrate that alterations in TNF-α production may be involved. PMID:20850784

A large national surgical registry was used to establish national benchmarks and associated predictors of major neurologic complications (i.e., coma and stroke) after surgical clipping of unruptured intracranial aneurysms. The American College of Surgeons National Surgical Quality Improvement Program data set between 2007 and 2013 was used for this retrospective cohort analysis. Demographic, comorbidity, and operative characteristics associated with the development of a major neurologic complication (i.e., coma or stroke) were elucidated using a backward selection stepwise logistic regression analysis. This model was subsequently used to fit a predictive score for major neurologic complications. Inclusion criteria were met by 662 patients. Of these patients, 57 (8.61%) developed a major neurologic complication (i.e., coma or stroke) within the 30-day postoperative period. On multivariable analysis, operative time (log odds 0.004 per minute; 95% confidence interval [CI], 0.002-0.007), age (log odds 0.05 per year; 95% CI, 0.02-0.08), history of chronic obstructive pulmonary disease (log odds 1.26; 95% CI, 0.43-2.08), and diabetes (log odds 1.15; 95% CI, 0.38-1.91) were associated with an increased odds of major neurologic complications. When patients were categorized according to quartile of a predictive score generated from the multivariable analysis, rates of major neurologic complications were 1.8%, 4.3%, 6.7%, and 21.2%. Using a large, national multi-institutional cohort, this study established representative national benchmarks and a predictive scoring system for major neurologic complications following operative management of unruptured intracranial aneurysms. The model may assist with risk stratification and tailoring of decision making in surgical candidates. Copyright © 2016 Elsevier Inc. All rights reserved.

Novel treatment alternatives for feline ureteral obstruction(s) include placement of a double pigtail ureteral stent and a subcutaneous ureteral bypass (SUB) device. This study evaluated parameters for the prediction of hospitalization times, peri-operative survival, renal recovery and long-term survival in cats with benign ureteral obstructions after successful decompression with either a ureteral stent or SUB device. The medical records of 41 cats treated for benign ureteral obstruction(s) were retrospectively reviewed. Preoperative historical, biochemical and imaging parameters, along with intra- and postoperative biochemical parameters and complications were evaluated for predictors of hospitalization length, survival to discharge, 3-, 6- and 9-month post-procedure creatinine, and overall survival time. All patients had successful decompression of their renal pelvis. Hospitalization time was positively associated with presenting creatinine, perioperative complications, post-procedure creatinine and potassium, but was negatively associated with post-procedure sodium. No parameters were associated with survival to discharge. A higher creatinine at discharge was positively associated with a higher creatinine at follow-up. A decreased overall survival was associated with a higher presenting blood urea nitrogen, higher creatinine at hospital discharge and in over-hydrated patients during hospitalization. Cats with International Renal Interest Society stage 1 and 2 kidney disease, versus stage 3 and 4, at 3 months and 6 months post-procedure, lived longer. Cats with ureteral obstruction(s) treated with a ureteral stent or SUB device had an overall good survival and no admitting parameter was associated with survival to discharge. No single parameter was associated with all outcomes in this study, making predicting patient survival and cost prior to ureteral decompression difficult.

The chronic obstructive pulmonary disease or COPD is a slowly progressive disease whose course is frequently the subject of acute episodes, of variable severity, although, in general, reversible, called acute exacerbations. In the past five years (between 2008 and 2013), seven prognostic scores have been published to try to assess the short-term risk of these acute exacerbations. Their components and characteristics are analysed and commented upon. An Internet program with a detailed compilation of the main features of these scores (www.medhyg.ch/scoredoc) supplements this review.

Researches have shown positive correlation between periodontitis and respiratory diseases such as chronic obstructive pulmonary disease. We reviewed the literature to assess the relationship between periodontitis and respiratory diseases. This study involved a review of relevant English literature published regarding periodontitis and respiratory diseases during the period of 1994-2015. The analysis of literature related to the topic showed there is association between periodontitis and respiratory diseases such as chronic obstructive pulmonary disease and pneumonia. It was found that periodontitis is associated with respiratory diseases due to poor oral hygiene and low immunity state.

Abstract Cachexia and muscle wasting are well recognized as common and partly reversible features of chronic obstructive pulmonary disease (COPD), adversely affecting disease progression and prognosis. This argues for integration of weight and muscle maintenance in patient care. In this review, recent insights are presented in the diagnosis of muscle wasting in COPD, the pathophysiology of muscle wasting, and putative mechanisms involved in a disturbed energy balance as cachexia driver. We discuss the therapeutic implications of these new insights for optimizing and personalizing management of COPD‐induced cachexia. PMID:27066314

To evaluate the effectiveness of double silicone intubation for the management of partial lacrimal drainage system obstruction in adults. Observational retrospective case series. Twenty-four eyes of 18 consecutive adult patients with partial lacrimal system obstruction managed at the University of Michigan. Retrospective review of symptoms and signs, duration of silicone intubation, and complications. Resolution of tearing. Preoperative tearing, negative Jones I testing, positive Jones II testing, and resistance to positive-pressure irrigation were present in all eyes (100%). The first silicone tube was removed after a mean of 11+/-7 months, and the second tube after 16+/-6 months. Postoperatively, at a mean of 21+/-9 months after removal of both tubes, tearing remained resolved in 19 eyes (79%) and remained improved in 2 eyes (8%). In eyes with resolved tearing, Jones I testing became positive, and there was no resistance to positive-pressure irrigation. Persistent tearing in 3 eyes (13%) required treatment with external dacryocystorhinostomy. The only complication was peripunctal pyogenic granulomas in 2 eyes. Double silicone intubation is an effective minimally invasive technique for treatment of partial lacrimal system obstruction in adults.

Oesophageal stricture is a complication of oesophageal reflux and may itself be complicated by bolus obstruction. We reviewed the records of patients presenting with dysphagia and who were found to have benign oesophageal strictures. We studied the outcome of bolus obstruction in 13 episodes affecting eight patients. In six episodes Coca-Cola was administered on the day before endoscopy, and in all these patients the bolus had cleared. In seven episodes nothing was administered before endoscopy, and in all seven a bolus was evident at endoscopy. In five of these seven the bolus was removed piecemeal and in each of these instances the endoscope had to be passed between two and five times. In the remaining two instances the procedure was abandoned and the patients returned to the ward for the administration of Coca-Cola. At subsequent endoscopy these patients were found to be clear of any bolus. These results suggest that the administration of Coca-Cola (or other aerated drinks) may clear a bolus in the acutely obstructed oesophagus. PMID:8476194

Reconstruction of chronic type B dissection and thoracoabdominal aortic aneurysm (TAAA) remaining after the emergency reconstruction of the ascending thoracic aorta and aortic arch for acute type A dissection represents one of the major surgical challenges. Complications of chronic type B dissection are aneurysmal formation and rupture of an aortic aneurysm with a high mortality rate. We presented a case of visceral hybrid reconstruction of TAAA secondary to chronic dissection type B after the Bentall procedure with the 'elephant trunk' technique due to acute type A aortic dissection in a high-risk patient. A 62 year-old woman was admitted to our institution for reconstruction of Crawford type I TAAA secondary to chronic dissection. The patient had had an acute type A aortic dissection 3 years before and undergone reconstruction by the Bentall procedure with the 'elephant trunk' technique with valve replacement. On admission the patient had coronary artery disease (myocardial infarction, two times in the past 3 years), congestive heart disease with ejection fraction of 25% and chronic obstructive pulmonary disease. On computed tomography (CT) of the aorta TAAA was revealed with a maximum diameter of 93 mm in the descending thoracic aorta secondary to chronic dissection. All the visceral arteries originated from the true lumen with exception of the celiac artery (CA), and the end of chronic dissection was below the origin of the superior mesenteric artery (SMA). The patient was operated on using surgical visceral reconstruction of the SMA, CA and the right renal artery (RRA) as the first procedure. Postoperative course was without complications. Endovascular TAAA reconstruction was performed as the second procedure one month later, when the 'elephant trunk' was used as the proximal landing zone for the endograft, and distal landing zone was the level of origin of the RRA. Postoperatively, the patient had no neurological deficit and renal, liver function and functions of the other abdominal organs were normal. Control CT after 6 months showed full exclusion of the aneurysm from the systemic circulation without endoleak and good flow through visceral anastomosis. In patients with comorbidities, like in the presented case, visceral hybrid reconstruction of chronic dissection type B with TAAA could be the treatment of choice.

The Contribution of Small Airway Obstruction to the Pathogenesis of Chronic Obstructive Pulmonary Disease.

PubMed

Hogg, James C; Paré, Peter D; Hackett, Tillie-Louise

2017-04-01

The hypothesis that the small conducting airways were the major site of obstruction to airflow in normal lungs was introduced by Rohrer in 1915 and prevailed until Weibel introduced a quantitative method of studying lung anatomy in 1963. Green repeated Rohrer's calculations using Weibels new data in 1965 and found that the smaller conducting airways offered very little resistance to airflow. This conflict was resolved by seminal experiments conducted by Macklem and Mead in 1967, which confirmed that a small proportion of the total lower airways resistance is attributable to small airways <2 mm in diameter. Shortly thereafter, Hogg, Macklem, and Thurlbeck used this technique to show that small airways become the major site of obstruction in lungs affected by emphysema. These and other observations led Mead to write a seminal editorial in 1970 that postulated the small airways are a silent zone within normal lungs where disease can accumulate over many years without being noticed. This review provides a progress report since the 1970s on methods for detecting chronic obstructive pulmonary disease, the structural nature of small airways' disease, and the cellular and molecular mechanisms that are thought to underlie its pathogenesis.

Enlarged thalamostriate vein causing unilateral Monro foramen obstruction. Case report.

PubMed

2009-06-01

Causes of unilateral hydrocephalus resulting from an obstruction at the Monro foramen include foraminal atresia, tumors, gliosis, contralateral shunting, and infectious and inflammatory conditions. However, few reports in the literature cite vascular lesions as the cause of the obstruction. To their knowledge, the authors present the first report of unilateral hydrocephalus occurring due to an abnormally enlarged thalamostriate vein independent of an arteriovenous malformation or developmental venous angioma. The condition was treated successfully by endoscopic septum pellucidum fenestration. A 28-year-old man was referred for evaluation due to a 10-year history of chronic headaches that worsened in severity over the past year. A CT scan of the head revealed unilateral right ventricular dilation. Cranial MR imaging with and without contrast administration showed a dilated right thalamostriate-internal vein complex without any evidence of associated arteriovenous malformation or venous angioma. Endoscopic exploration of the right lateral ventricle showed an enlarged subependymal thalamostriate vein obstructing the Monro foramen. An endoscopic fenestration of the septum pellucidum was performed, resulting in alleviation of the patient's symptoms. Abnormally enlarged venous structures may cause obstructive unilateral hydrocephalus and can be a rare cause of chronic, intermittent headaches in adults. Endoscopic fenestration of the septum pellucidum is an effective treatment.

Tuberculous bowel obstruction at a university teaching hospital in Northwestern Tanzania: a surgical experience with 118 cases

2013-01-01

Background Bowel obstruction resulting from intestinal tuberculosis has been reported to be more prevalent in developing countries including Tanzania. This study was undertaken to describe the clinicopathological profile, surgical management and outcome of tuberculous intestinal obstruction in our local setting and to identify factors responsible for poor outcome among these patients. Methods This was a prospective descriptive study of patients operated for tuberculous intestinal obstruction at Bugando Medical Centre (BMC) in northwestern Tanzania from April 2008 to March 2012. Ethical approval to conduct the study was obtained from relevant authorities. Statistical data analysis was performed using SPSS version 17.0. Results A total of 118 patients with tuberculous intestinal obstruction were studied. The male to female ratio was 1.8: 1. The median age was 26 years (range 11-67 years). The modal age group was 21-30 years. Thirty-one (26.3%) patients had associated pulmonary tuberculosis and 25 (21.2%) patients were HIV positive with a median CD4+ count of 225 cells /μl. Small bowel strictures were the most common operative findings accounting for 72.9% of cases. The ileo-caecal region was the commonest area of involvement in 68 (57.6%) patients. The right hemicolectomy with ileo-transverse anastomosis was the most frequent surgical procedure performed in 66 (55.9%) patients. Postoperatively all the patients received antituberculous drugs for a period of one year. Postoperative complication rate was 37.3% and surgical site infection (SSI) was the most frequent complication in 42.8% of cases. HIV positivity and low CD4+ count were the main predictors of SSI (p < 0.001). The overall median length of hospital stay was 24 days. Patients who had postoperative complications stayed longer in the hospital and this was statistically significant (p = 0.011). Mortality rate was 28.8% and it was significantly associated with co-existing medical illness, delayed presentation, HIV positivity, low CD 4 count (<200 cells/μl), ASA class and presence of complications (p < 0.001). The follow up of patients was generally poor as more than fifty percent of patients were lost to follow up. Conclusion Tuberculous bowel obstruction remains rampant in our environment and contributes significantly to high morbidity and mortality. The majority of patients present late when the disease becomes complicated. A high index of suspicion, proper evaluation and therapeutic trial in suspected patients is essential for an early diagnosis and timely definitive treatment, in order to decrease the morbidity and mortality associated with this disease.

To validate a prognostic score predicting major complications in patients with solid tumors and seemingly stable episodes of febrile neutropenia (FN). The definition of clinical stability implies the absence of organ dysfunction, abnormalities in vital signs, and major infections. We developed the Clinical Index of Stable Febrile Neutropenia (CISNE), with six explanatory variables associated with serious complications: Eastern Cooperative Oncology Group performance status ≥ 2 (2 points), chronic obstructive pulmonary disease (1 point), chronic cardiovascular disease (1 point), mucositis of grade ≥ 2 (National Cancer Institute Common Toxicity Criteria; 1 point), monocytes < 200 per μL (1 point), and stress-induced hyperglycemia (2 points). We integrated these factors into a score ranging from 0 to 8, which classifies patients into three prognostic classes: low (0 points), intermediate (1 to 2 points), and high risk (≥ 3 points). We present a multicenter validation of CISNE. We prospectively recruited 1,133 patients with seemingly stable FN from 25 hospitals. Complication rates in the training and validation subsets, respectively, were 1.1% and 1.1% in low-, 6.1% and 6.2% in intermediate-, and 32.5% and 36% in high-risk patients; mortality rates within each class were 0% in low-, 1.6% and 0% in intermediate-, and 4.3% and 3.1% in high-risk patients. Areas under the receiver operating characteristic curves in the validation subset were 0.652 (95% CI, 0.598 to 0.703) for Talcott, 0.721 (95% CI, 0.669 to 0.768) for Multinational Association for Supportive Care in Cancer (MASCC), and 0.868 (95% CI, 0.827 to 0.903) for CISNE (P = .002 for comparison between CISNE and MASCC). CISNE is a valid model for accurately classifying patients with cancer with seemingly stable FN episodes. © 2015 by American Society of Clinical Oncology.

To compare the clinical outcomes of uncovered and covered self-expandable metal stent placements in patients with malignant duodenal obstruction. A total of 67 patients were retrospectively enrolled from January 2003 to June 2013. All patients had symptomatic obstruction characterized by nausea, vomiting, reduced oral intake, and weight loss. The exclusion criteria included asymptomatic duodenal obstruction, perforation or peritonitis, concomitant small bowel obstruction, or duodenal obstruction caused by benign strictures. The technical and clinical success rate, complication rate, and stent patency were compared according to the placement of uncovered (n = 38) or covered (n = 29) stents. The technical and clinical success rates did not differ between the uncovered and covered stent groups (100% vs 96.6% and 89.5% vs 82.8%). There were no differences in the overall complication rates between the uncovered and covered stent groups (31.6% vs 41.4%). However, stent migration occurred more frequently with covered than uncovered stents [20.7% (6/29) vs 0% (0/38), P < 0.05]. Moreover, the overall cumulative median duration of stent patency was longer in uncovered than in covered stents [251 d (95%CI: 149.8 d-352.2 d) vs 139 d (95%CI: 45.5 d-232.5 d), P < 0.05 by log-rank test] The overall cumulative median survival period was not different between the uncovered stent (70 d) and covered stent groups (60 d). Uncovered stents may be preferable in malignant duodenal obstruction because of their greater resistance to stent migration and longer stent patency than covered stents.

Intestinal obstruction is a common complication associated with Meckel’s diverticulum in adults. The diverticulum itself or its fibrous band can lead to an intestinal volvulus, intussusceptions, or closed-loop obstructions, which require surgery. The incarceration of Meckel’s diverticulum in either inguinal or femoral hernia sacs (Littre’s hernia) is another, less common, etiology underlying intestinal obstruction. This case report describes a 45-year-old man who had an obstruction associated with a Meckel’s diverticulum that passed through a congenital defect in the mesocolon into the right subphrenic space. The patient, who had not undergone abdominal surgery previously, came to the emergency room with acute onset of intermittent epigastric pain and abdominal distention. Computed tomography images showed the presence of a segment of the small bowel and a diverticulum in the right subphrenic space and paracolic gutter. The twisted mesentery and the dilated loops of the proximal small bowel were indicative of an intestinal volvulus and obstruction. Meckel’s diverticulum complicated by a transmesocolic internal hernia was diagnosed, and this condition was confirmed during emergency surgery. The patient’s postoperative recovery was uneventful. This case report highlights another presentation of Meckel’s diverticulum, that is, in combination with a transmesocolic internal hernia. This etiology may lead to an intestinal volvulus and necessitate early surgery. PMID:25309093

Purpose. This study aims at comparing two different types of drainage tubes in conjunctivodacryocystorhinostomy, which are used for upper lacrimal system obstruction or damage, with respect to their respective postoperative problems and solutions. Methods. Nineteen eyes of 17 patients who underwent conjunctivodacryocystorhinostomy (CDCR) or conjunctivorhinostomy (CR) surgery with a Medpor coated tear drainage tube or silicon tube placement between October, 2010, and February, 2014, were included in this retrospective comparative study. Results. In the initial surgery, Medpor coated tear drainage tubes were used in 11 eyes by CDCR, whereas silicon tear drainage tubes were implanted into 2 eyes by CR and 6 eyes by CDCR. In group 1, proximal and distal obstructions developed postoperatively in 4 eyes, while 1 eye showed tube malposition and 3 eyes developed luminal obstruction by debris 3 times. In group 2, tube extrusion developed in 4 eyes, whereas tube malposition developed in 6 eyes and luminal obstruction by debris developed in 6 eyes at different times, for a total of 20 times. Conclusions. In our study, the most significant complication we observed in the use of silicon tear drainage tubes was tube extrusion,whereas the leading complication related to the use of Medpor coated tear drainage tubes was tube obstruction.

Acute exacerbations of chronic obstructive pulmonary disease (COPD) increase the risk of death and drive healthcare costs, but whether they accelerate loss of lung function remains controversial. Whether exacerbations in subjects with mild COPD or similar acute respiratory events in smokers without airflow obstruction affect lung function decline is unknown. To determine the association between acute exacerbations of COPD (and acute respiratory events in smokers without COPD) and the change in lung function over 5 years of follow-up. We examined data on the first 2,000 subjects who returned for a second COPDGene visit 5 years after enrollment. Baseline data included demographics, smoking history, and computed tomography emphysema. We defined exacerbations (and acute respiratory events in those without established COPD) as acute respiratory symptoms requiring either antibiotics or systemic steroids, and severe events by the need for hospitalization. Throughout the 5-year follow-up period, we collected self-reported acute respiratory event data at 6-month intervals. We used linear mixed models to fit FEV 1 decline based on reported exacerbations or acute respiratory events. In subjects with COPD, exacerbations were associated with excess FEV 1 decline, with the greatest effect in Global Initiative for Chronic Obstructive Lung Disease stage 1, where each exacerbation was associated with an additional 23 ml/yr decline (95% confidence interval, 2-44; P = 0.03), and each severe exacerbation with an additional 87 ml/yr decline (95% confidence interval, 23-151; P = 0.008); statistically significant but smaller effects were observed in Global Initiative for Chronic Obstructive Lung Disease stage 2 and 3 subjects. In subjects without airflow obstruction, acute respiratory events were not associated with additional FEV 1 decline. Exacerbations are associated with accelerated lung function loss in subjects with established COPD, particularly those with mild disease. Trials are needed to test existing and novel therapies in subjects with early/mild COPD to potentially reduce the risk of progressing to more advanced lung disease.

The self-expandable metal stent (SEMS) can alleviate malignant colonic obstruction and avoid emergency decompressive surgery. To document performance, safety, and effectiveness of colorectal stents used per local standards of practice in patients with malignant large-bowel obstruction to avoid palliative stoma surgery in incurable patients (PAL) and facilitate bowel decompression as a bridge to surgery for curable patients (BTS). Prospective clinical cohort study. Two global registries with 39 academic and community centers. This study involved 447 patients with malignant colonic obstruction who received stents (255 PAL, 182 BTS, 10 no indication specified). Colorectal through-the-scope SEMS placement. The primary endpoint was clinical success at 30 days, defined as the patient's ability to maintain bowel function without adverse events related to the procedure or stent. Secondary endpoints were procedural success, defined as successful stent placement in the correct position, symptoms of persistent or recurrent colonic obstruction, and complications. The procedural success rate was 94.8% (439/463), and the clinical success rates were 90.5% (313/346) as assessed on a per protocol basis and 71.6% (313/437) as assessed on an intent-to-treat basis. Complications included 15 (3.9%) perforations, 3 resulting in death, 7 (1.8%) migrations, 7 (1.8%) cases of pain, and 2 (0.5%) cases of bleeding. No control group. No primary endpoint analysis data for 25% of patients. This largest multicenter, prospective study of colonic SEMS placement demonstrates that colonic SEMSs are safe and highly effective for the short-term treatment of malignant colorectal obstruction, allowing most curable patients to have 1-step resection without stoma and providing most incurable patients minimally invasive palliation instead of surgery. The risk of complications, including perforation, was low. Copyright © 2011 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc. All rights reserved.

Methodological considerations, such as directed acyclic graphs, for studying "acute on chronic" disease epidemiology: chronic obstructive pulmonary disease example.

PubMed

Tsai, Chu-Lin; Camargo, Carlos A

2009-09-01

Acute exacerbations of chronic disease are ubiquitous in clinical medicine, and thus far, there has been a paucity of integrated methodological discussion on this phenomenon. We use acute exacerbations of chronic obstructive pulmonary disease as an example to emphasize key epidemiological and statistical issues for this understudied field in clinical epidemiology. Directed acyclic graphs are a useful epidemiological tool to explain the differential effects of risk factor on health outcomes in studies of acute and chronic phases of disease. To study the pathogenesis of acute exacerbations of chronic disease, case-crossover design and time-series analysis are well-suited study designs to differentiate acute and chronic effect. Modeling changes over time and setting appropriate thresholds are important steps to separate acute from chronic phases of disease in serial measurements. In statistical analysis, acute exacerbations are recurrent events, and some individuals are more prone to recurrences than others. Therefore, appropriate statistical modeling should take into account intraindividual dependence. Finally, we recommend the use of "event-based" number needed to treat (NNT) to prevent a single exacerbation instead of traditional patient-based NNT. Addressing these methodological challenges will advance research quality in acute on chronic disease epidemiology.

Gallstone disease is common. However, a proportion of patients are asymptomatic and remain undiagnosed until the occurrence of complications. Common complications include acute cholecystitis, biliary obstruction, acute pancreatitis and cholangitis. Severe complications include gallbladder perforation, Mirizzi syndrome and fistula formation are usually associated with significant morbidity and mortality. We report a case of asymptomatic spotaneous gallbladder perforation due to acute cholecystitis. PMID:24914424

Gastric outlet obstruction is a complication that can occur in the evolution of patients with pancreatic adenocarcinoma. Self-expanding metal stents (SEMS) resolve this situation by endoscopy, thus avoiding a laparoscopic gastroenterotomy. The aim of our study is to report our experience in the palliative treatment with SEMS of gastroduodenal neoplasic obstruction at a monovalent gastroenterology institute in Mar del Plata. All patients with symptoms of gastric outlet obstruction of neoplasic origin who fit for SEMS between January 2006 and February 2011 were included. Data were collected regarding the patients' clinical characteristics as well as the type of tumor and the efficacy of the procedure measured according to success and complication rates, length of hospital stay and evaluation of clinical benefit, according to performance status scales and gastric outlet obstruction score (GOOS). A total of 17 prosthesis placed in 16 patients were analyzed. In all cases the procedure was completed successfully. The intervention was performed on an outpatient basis in 12 patients (75%). One patient presented within 7 days gastric haemorrhage related with the stent, who was early treated with argon plasma. Late expected com- plications due to prolonged survival were observed in 60% of patients. None of them was serious and resolved spontaneously or by endoscopic treatment. Average survival was 117 days (range 3 to 300 days) and most patients showed subjective improvement in GOOS scale. SEMS have a high rate of technical and clinical success. However, they are scarcely known in our field. They present an insignificant number of early complications and the resolution of later ones is quite easy. An improvement in GOOS scale and quality of life is achieved.

Exhaled nitric oxide levels in exacerbations of asthma, chronic obstructive pulmonary disease and pneumonia.

Nitric oxide is known to be present in the exhaled air of normal subjects and at higher concentrations in asthmatics. The aim of this study was to measure exhaled nitric oxide levels in patients admitted to hospital with acute exacerbations of asthma, or chronic obstructive pulmonary disease, or with pneumonia. Within 24 hours of admission exhaled nitric oxide levels were measured by a chemiluminescent analyzer in 11 patients with acute sever asthma, 19 patients with acute exacerbation of chronic obstructive pulmonary disease, and in 12 patients with pneumonia. In asthmatics measurements were made on 3 occasions, at day 1, 4, and 28 and were related to changes in peak expiratory flow rate. On admission median exhaled nitric oxide levels (range) were significantly higher in asthmatics 22 (9.3-74) parts per billion in comparison to patients with chronic obstructive pulmonary disease 10.3 (2.7-34) parts per billion; p < 0.01, pneumonia 7 (4-17) parts per billion; p<0.001, and normal subjects 8.7 (5-13.3) parts per billion; p < 0.001. Following treatment the asthmatics had a significant reduction in their exhaled nitric oxide levels from 22 (9.3-74) parts per billion on day 1 to 9.7 (5.7-18.3) parts per billion on day 28; p = 0.005. Peak expiratory flow rate measurements increased from 200 (120-280) l/min on day 1 to 280 (150-475) l/min on day 4; p < 0.05 and to 390 (150-530) l/min on day 28; p < 0.01. A strong negative correlation existed between peak expiratory flow rate measurements and exhaled nitric oxide levels in asthmatics on day 28 (r = -0.70; p = 0.017). Acute exacerbations of asthma are associated with increased levels of exhaled nitric oxide in contrast to exacerbations of chronic obstructive pulmonary disease and acute pneumonia. Exhaled nitric oxide may be a useful indirect marker of asthmatic airway inflammation. The differing time course of response of nitric oxide to peak flow measures suggests that these two measures are reflecting differing airway events.
