    This investigation was aimed at the complex evaluation of the reactivity mechanisms of bronchial smooth muscle tissue (SMT) in experimental bronchial spasm. Morphometric, cytospectrophotometric and electron microscopical analysis demonstrated the presence of three types of smooth muscle cells (SMC) within the bronchial SMT (small, medium, large), that differed in their linear and metabolic parameters. The findings of this study indicate that under the conditions of experimental bronchial spasm development, the ratios of SMC in bronchial SMT are changed with the increase in proportion of small SMC and the elimination of large SMC. In the dynamics of experimental bronchial spasm development, the activation of cytoplasmic synthesis as well as of DNA synthesis was detected mainly in group of small SMC. The reactive-dystrophic changes were marked at the subcellular level, that were most often identified in large SMC resulting in their elimination from population in the dynamics of an experiment. The data obtained suggest that one of the important mechanisms of airway SMT adaptation to the bronchial spasm development is a dynamic reorganization of SMC population.

    Hemifacial spasm is one of the two most common craniofacial movement disorders (blepharospasm is the second one). It is characterised by unilateral involuntary contractions of muscles involved in facial expression that are innervated by the facial nerve. Most of the time, hemifacial spasm is a peripherally-induced movement disorder caused by vascular compression of the facial nerve near its origin from the brainstem. Although it is a benign condition, it can cause significant cosmetic and functional disability. It is a chronic disease and spontaneous recovery is very rare. The two treatments that are really efficient and routinely available are microvascular decompression and botulinum toxin muscular injections.

    Facial tics and spasms are socially incapacitating, but effective treatment is often available. The clinical picture is sufficient for distinguishing between the different diseases that cause this affliction.We describe three cases of patients with facial tics or spasms: one case of tics, which are familiar to many physicians; one case of blepharospasms; and one case of hemifacial spasms. We discuss the differential diagnosis and the treatment possibilities for facial tics and spasms. Early diagnosis and treatment is important, because of the associated social incapacitation. Botulin toxin should be considered as a treatment option for facial tics and a curative neurosurgical intervention should be considered for hemifacial spasms.

    Palmaris brevis spasm syndrome is a rare and benign condition of localised muscular hyperactivity. In five men, the hypothenar eminence underwent spontaneous, irregular, tonic contractions of the palmaris brevis muscle. An EMG showed spontaneous high frequency discharges of normal motor units, without evidence of neuropathy or of nerve compression. This syndrome resembles other restricted muscle hyperactivity syndromes although there are some differences. Curiously, the palmaris brevis muscle...

    Spasm of accommodation refers to prolonged contraction of the ciliary muscle, most commonly causing pseudomyopia to varying degrees in both eyes by keeping the lens in a state of short sightedness. It may also be manifested as inability to allow the adaptation spasticity prevailing in the ciliary muscle relax without measurable myopia. As a rule, this is a functional ailment triggered by prolonged near work and stress. The most common symptoms include blurring of distance vision, varying visual acuity as well as pains in the orbital region and the head, progressing into a chronic state. Cycloplegic eye drops are used as the treatment.

    Full Text Available Bronchial stents are mostly used as a Palliative relief of symptoms often caused by airway obstruction, It is also used for sealing of stump fistulas after pneumonectomy and dehiscence after bronchoplastic operations. Advances in airway prosthetics have provided a variety of silicone stents, expandable metal stents, and pneumatic dilators, enabling the correction of increasingly complex anatomical problems. Several series have been published describing the application and results of these techniques. This manuscript reviews the historical development of stents, types, indication, outcome, and complications. Alternative therapies for tracheobronchial stenting were also reviewed

Iran J Child Neurol. 2014 Summer;8(3: 1-5.AbstractObjectiveInfantile spasm (IS is a convulsive disease characterized by brief, symmetric axial muscle contraction (neck, trunk, and/or extremities. IS is a type of seizure that was first described by West in 1841, who witnessed the seizure in his own son. West’s syndrome refers to the classic triad of spasms, characteristic EEG, and neurodevelopmental regression. Most cases involve flexors and extensors,but either of the types may be involved independently.IS, as its name implies, most often occurs during the first year of life with an incidence of approximately 1 per 2000-4000 live births. Most, but not all, patients with this disorder have severe EEG abnormalities; this pattern was originallyreferred to as hypsarrhythmia by Gibbs and Gibbs. Cases with known etiology or signs of brain damage are considered as symptomatic. The Overall prognosis of the disease is poor. Peak onset age of the epileptic syndrome is 3 to 7 months, which mainly occurs before 2 years of age in 93% of patients. Hypsarrhythmia is the EEG hallmark of IS, which comprised a chaotic, bilaterally asynchronous high-voltage polyspike, and slow wave discharges interspersed with multifocal spikes and slow waves.Etiological classification is as follows: 1 Symptomatic: with identifiable prenatal, perinatal, and postnatal causes with developmental delay at the presentation time; 2 Cryptogenic: unknown underlying cause, normal development at the onset of spasms, normal neurological exam and neuroimaging, and no abnormality in the metabolic evaluation; 3 Idiopathic: pure functional cerebral dysfunction with complete recovery, no residual dysfunction, normal neuroimaging and normal etiologic evaluation, and normal neurodevelopment.ReferencesInfantile Spasms.

    Full Text Available Background: Few papers address the comprehensive prognosis in infantile spasms and look into the seizure profile and psychomotor outcome. Objective: We aimed to follow up children with infantile spasms to study: a the etiology, demographics, semiology, electroencephalogram (EEG, and radiological pattern; b seizure control, psychomotor development, and EEG resolution with treatment; c the effects of various factors on the control of spasms, resolution of EEG changes, and psychomotor development at 3-year follow-up. Materials and Methods: Fifty newly diagnosed cases with a 1-12 month age of onset and who had hypsarrhythmia in their EEG were recruited and 43 were followed up for 3 years. Results: Of the children followed up, 51% were seizure-free and 37% had a normal EEG at the 3-year follow-up. Autistic features were seen in 74% of the children. Only 22.7% among the seizure-free (11.6% of the total children had normal vision and hearing, speech with narration, writing skills, gross and fine motor development, and no autism or hyperactivity. On multivariate analysis, two factors could predict bad seizure outcome — the occurrence of other seizures in addition to infantile spasms and no response to 28 days of adrenocorticotropic hormone (ACTH. No predictor could be identified for abnormal psychomotor development. Discussion and Conclusion: In our study, we could demonstrate two factors that predict seizure freedom. The cognitive outcome and seizure control in this group of children are comparable to the existing literature. However, the cognitive outcome revealed by our study and the survey of the literature are discouraging.

    Full Text Available Multivessel coronary spasm resulting to cardiogenic shock and malignant ventricular arrhythmias though rare has been reported in the literature. The disease seems to be more prevalent in Asians. There have been isolated reports of coronary spasm in patients with reactive airway disease. We report the first case of spontaneous multivessel spasm in a male patient with bronchial asthma of Arab ethnicity resulting in acute myocardial infarction complicated by cardiogenic shock, recurrent ventricular arrhythmias, and transient complete heart block. Literature review of similar cases suggests a strong association with bronchial asthma and a more malignant course in patients with reactive airway disease. The role of intracoronary nitroglycerin in proving the diagnosis even in patients in shock on maximal inotropic supports and intra-aortic balloon pump is highlighted and the importance of considering multivessel coronary spasm as a cause for acute coronary syndrome even in patients with conventional risk factors for atherosclerotic coronary artery disease is reinforced in the discussion of this case.

    Liposteroid was administered intravenously to 6 patients with refractory epileptic spasms. In one case, the spasms initially disappeared but then reappeared after three months. Another case had a transient and slight decrease of epileptic spasms. In the only patient in whom spasms disappeared, EEG abnormalities were greatly improved with diffuse spikes and waves changing into focal spikes. Two cases displayed hyperexcitability, insomnia and acting out behavior, and the therapy was discontinued in one of them. One case had appetite loss and another showed an increase in tonic seizures. No patient had serious adverse effects such as infection, edema, subdural hematoma and brain shrinkage. Although liposteroid therapy has been recommended as an easy, useful and safe alternative for ACTH, we found considerable adverse effects and only a small effect on refractory spasms, and conclude that the regimen should be modified.

    Muscular spasm is type of the increased muscle tone which is common in the upper motor neuron lesion and it can be developed due to disease (stroke, MS, tumors, infection, intoxication) and trauma. This research included 30 patients with muscular spasm after upper motor neuron lesion. All of the patients were treated by passive exercises and stretching of agonists and antagonists. All patients were males, with age between 25 and 45 years (average 26.9 years). Applying t-test, in testing significant differences in changing muscular spasm, in relationship to the length of the kinesitherapy treatment, there were no significant differences between 1st and 15th day of treatment. Significant difference in spasm grades was after 30th day of treatment compare to 1st and 15th day. This research showed that decreasing muscle spasm we could be expected by applying the kinesitherapy procedures for a longer time.

    @@ Case History Ms. Zheng from Singapore, aged 51 years, paid her first visit on Aug.30, 2006, with the chief complaint of left facial paralysis accompanied with facial spasm for 5 years. The patient got left facial paralysis in 2001, which was not completely cured, and developed into facial spasm one year later. Although she had received various treatments including surgical operation, the disease was not cured. At the moment she had discomfort and dull sensation in the left facial area, mainly accompanied with twitching of the peripheral nerve of the eye. She was also accompanied with posterior auricular muscle tension and discomfort. She had fairly good sleep and appetite, but slightly quick temper. Physical examination at the moment showed that the patient had a slightly thin body figure, flushing face, and good mental state. The blood pressure was 110/75mmHg and the heart rate was 85 beats/min. No abnormal signs were found in the heart and lungs. The facial examination showed mild swelling of the left side of the face, incomplete closing of the eye lids, disappearance of wrinkles on the forehead, shallow nasolabial groove, and obvious muscle tension and tenderness in the left opisthotic region. Careful observation could find slight facial muscular twitching. The tongue proper was red with little coating, and the pulse thready-wiry.

  18. The many faces of hemifacial spasm: differential diagnosis of unilateral facial spasms.

    2011-08-01

    Hemifacial spasm is defined as unilateral, involuntary, irregular clonic or tonic movement of muscles innervated by the seventh cranial nerve. Most frequently attributed to vascular loop compression at the root exit zone of the facial nerve, there are many other etiologies of unilateral facial movements that must be considered in the differential diagnosis of hemifacial spasm. The primary purpose of this review is to draw attention to the marked heterogeneity of unilateral facial spasms and to focus on clinical characteristics of mimickers of hemifacial spasm and on atypical presentations of nonvascular cases. In addition to a comprehensive review of the literature on hemifacial spasm, medical records and videos of consecutive patients referred to the Movement Disorders Clinic at Baylor College of Medicine for hemifacial spasm between 2000 and 2010 were reviewed, and videos of illustrative cases were edited. Among 215 patients referred for evaluation of hemifacial spasm, 133 (62%) were classified as primary or idiopathic hemifacial spasm (presumably caused by vascular compression of the ipsilateral facial nerve), and 4 (2%) had hereditary hemifacial spasm. Secondary causes were found in 40 patients (19%) and included Bell's palsy (n=23, 11%), facial nerve injury (n=13, 6%), demyelination (n=2), and brain vascular insults (n=2). There were an additional 38 patients (18%) with hemifacial spasm mimickers classified as psychogenic, tics, dystonia, myoclonus, and hemimasticatory spasm. We concluded that although most cases of hemifacial spasm are idiopathic and probably caused by vascular compression of the facial nerve, other etiologies should be considered in the differential diagnosis, particularly if there are atypical features.

    2006-09-01

    We aimed to investigate to which extent posterior auricular muscle (PAM) was affected and whether it contributed to the reflex activity in hemifacial spasm (HFS) patients. 19 HFS patients' spasm activities were recorded from facial muscles. Spasm activity of PAM was recorded synchronously on the symptomatic side in all patients. Lateral spread of blink reflex to orbicularis oris and PAMs were recorded in all but two patients. Botulinum toxin was applied to the PAM with the 14 patients presenting tinnitus, "clicking" or a "ticking" sound on the sane side and other positive auricular symptoms. After treatment, there was symptomatic improvement in 9 of 14 patients. The patients presenting with auricular symptoms and showing spasm activity in their PAMs can be thought as a candidate for botulinum toxin treatment scheme.

    Background: Bronchial asthma is an allergic pulmonary disease. The attack is mostly induced by the inhalation of or contact with allergens, such as pollens, dusts, insects (such as mite), germs, etc. During the attack, patients have severe dyspnea which is due to spasm of bronchial smooth muscles, swelling of the bronchial mucosa, and hypersecretion of the mucus, leading to bronchial obstruction.

    2016-02-01

    Bronchial carcinoids are uncommon pulmonary neoplasms and represent 1 to 2 % of all lung tumors. In early stage of disease, the mainstay and only curative treatment is surgery. Bronchial carcinoids are generally regarded as low-grade carcinomas and metastatic dissemination is unusual. The management of the metastatic stage is not currently standardized due to a lack of relevant studies. As bronchial carcinoids and in particular their metastatic forms are rare, we apply treatment strategies that have been evaluated in gastrointestinal and pancreatic neuroendocrine tumors. However, bronchial carcinoids have their own characteristic. A specific therapeutic feature of these metastatic tumors is that they require a dual approach: both anti-secretory for the carcinoid syndrome, and anti-tumoral.

  3. Distal esophageal spasm: an update.

    Science.gov (United States)

    Achem, Sami R; Gerson, Lauren B

    2013-09-01

    Distal esophageal spasm (DES) is an esophageal motility disorder that presents clinically with chest pain and/or dysphagia and is defined manometrically as simultaneous contractions in the distal (smooth muscle) esophagus in ≥20% of wet swallows (and amplitude contraction of ≥30 mmHg) alternating with normal peristalsis. With the introduction of high resolution esophageal pressure topography (EPT) in 2000, the definition of DES was modified. The Chicago classification proposed that the defining criteria for DES using EPT should be the presence of at least two premature contractions (distal latencylong acting), calcium-channel blockers, anticholinergic agents, 5-phosphodiesterase inhibitors, visceral analgesics (tricyclic agents or SSRI), and esophageal dilation. Acid suppression therapy is frequently used, but clinical outcome trials to support this approach are not available. Injection of botulinum toxin in the distal esophagus may be effective, but further data regarding the development of post-injection gastroesophageal reflux need to be assessed. Heller myotomy combined with fundoplication remains an alternative for the rare refractory patient. Preliminary studies suggest that the newly developed endoscopic technique of per oral endoscopic myotomy (POEM) may also be an alternative treatment modality.

    Hemifacial spasm (HFS) is characterized by involuntary unilateral contractions of the muscles innervated by the ipsilateral facial nerve, usually starting around the eyes before progressing inferiorly to the cheek, mouth, and neck. Its prevalence is 9.8 per 100,000 persons with an average age of onset of 44 years. The accepted pathophysiology of HFS suggests that it is a disease process of the nerve root entry zone of the facial nerve. HFS can be divided into two types: primary and secondary. Primary HFS is triggered by vascular compression whereas secondary HFS comprises all other causes of facial nerve damage. Clinical examination and imaging modalities such as electromyography (EMG) and magnetic resonance imaging (MRI) are useful to differentiate HFS from other facial movement disorders and for intraoperative planning. The standard medical management for HFS is botulinum neurotoxin (BoNT) injections, which provides low-risk but limited symptomatic relief. The only curative treatment for HFS is microvascular decompression (MVD), a surgical intervention that provides lasting symptomatic relief by reducing compression of the facial nerve root. With a low rate of complications such as hearing loss, MVD remains the treatment of choice for HFS patients as intraoperative technique and monitoring continue to improve.

    Severe scoliosis may have a significant effect on respiratory function. The effect is most often restrictive due to severe anatomical distortion of the chest, leading to reduced lung volumes, limited diaphragmatic excursion and chest wall muscle inefficiency. Bronchial compression by the deformed spine may also occur but is more unusual. Management options include a conservative approach using bracing and physiotherapy in mild cases, as well as surgical correction of the scoliosis in more severe cases. Bronchial stenting has also been used successfully as an alternative to surgical correction, and in cases in which spinal surgery was either unsuccessful or not feasible. The authors present a case involving a 52-year-old woman who exhibited symptomatic compression of the bronchus intermedius by severe residual scoliosis despite previous corrective surgery. She was treated with an indwelling bronchial stent.

  12. Facial nerve palsy and hemifacial spasm.

    Science.gov (United States)

    Valls-Solé, Josep

    2013-01-01

    Facial nerve lesions are usually benign conditions even though patients may present with emotional distress. Facial palsy usually resolves in 3-6 weeks, but if axonal degeneration takes place, it is likely that the patient will end up with a postparalytic facial syndrome featuring synkinesis, myokymic discharges, and hemifacial mass contractions after abnormal reinnervation. Essential hemifacial spasm is one form of facial hyperactivity that must be distinguished from synkinesis after facial palsy and also from other forms of facial dyskinesias. In this condition, there can be ectopic discharges, ephaptic transmission, and lateral spread of excitation among nerve fibers, giving rise to involuntary muscle twitching and spasms. Electrodiagnostic assessment is of relevance for the diagnosis and prognosis of peripheral facial palsy and hemifacial spasm. In this chapter the most relevant clinical and electrodiagnostic aspects of the two disorders are reviewed, with emphasis on the various stages of facial palsy after axonal degeneration, the pathophysiological mechanisms underlying the various features of hemifacial spasm, and the cues for differential diagnosis between the two entities.

  13. Bronchial Thermoplasty in Asthma

    Directory of Open Access Journals (Sweden)

    Wayne Mitzner

    2006-01-01

    Full Text Available In this review we discuss the potential of a new procedure, termed Bronchial Thermoplasty to prevent serious consequences resulting from excessive airway narrowing. The most important factor in minimizing an asthmatic attack is limiting the degree of smooth muscle shortening. The premise that airway smooth muscle can be either inactivated or obliterated without any long-term alteration of other lung tissues, and that airway function will remain normal, albeit with reduced bronchoconstriction, has now been demonstrated in dogs, a subset of normal subjects, and mild asthmatics. Bronchial Thermoplasty may thus develop into a useful clinical procedure to effectively impair the ability for airway smooth muscle to reach the levels of pathologic narrowing that characterizes an asthma attack. It may also enable more successful treatment of asthma patients who are unresponsive to more conventional therapies. Whether this will remain stable for the lifetime of the patient still remains to be determined, but at the present time, there are no indications that the smooth muscle contractility will return. This successful preliminary experience showing that Bronchial Thermoplasty could be safely performed in patients with asthma has led to an ongoing clinical trial at a number of sites in Europe and North America designed to examine the effectiveness of this procedure in subjects with moderately severe asthma.

    Asthma is an inflammatory disease of the airways clinically characterised by recurrent bronchial obstructions at least partially reversible. Recent epidemiologic data suggest that asthmatics have an increased rate of decrease of their expiratory volumes during life. This irreversible lung function impairment is associated with fundamental structural changes of the bronchial wall in terms of conjunctive tissue and smooth muscle composition. We describe these changes and explore the different mechanisms proposed to explain these structural modifications. We also review their consequences in terms of bronchial physiology and their potential influence on bronchial hyperresponsiveness.

Botulinum toxin therapy is an excellent noninvasive tool to treat this condition. However, surgical decompression of the aberrant vessel is also an upcoming approach to therapy for this condition.

    We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma. We decide to perform a lobectomy which for the tumor location and the lung condition has to be medium and lower right. We proceed to remove the adenopaty of hilium not affected by the tumor. The postoperative period develops without incidents. A check-up bronchoscopy performed three months later shows two polypoid masses in the right bronchial tube which, once a biopsy is performed, proved to be granulation tissue. Twelve months after undergoing surgery, the patient's condition is good, there is no evidence of tumor relapse and the breathing capacity is adequate, though there is an obstructive restrictive pattern in the espirometry. Even taking into consideration that lung tumors are extremely unusual, the epidermoid carcinoma is the one which most frequently occurs. The tumor's low malignancy is a sign that points to a good prognosis. Performing conservative surgery by means of bronchoplasty should be taken into account so as to keep the sequelae on the lung condition to a minimum, even though in this case the tumor location made it impossible.

    Coronary (artery) spasm plays an important role in the pathogenesis of ischemic heart disease, including stable angina, unstable angina, myocardial infarction, and sudden death. The prevalence of coronary spasm differs among populations, is higher in Japan and Korea than in the Western countries probably due to genetic as well as environmental factors. Coronary spasm occurs most often from midnight to early morning and is usually not induced by exercise in the daytime. The attacks of coronary spasm are associated with either ST segment elevation or depression, or negative U wave on ECG. Patients with multi-vessel coronary spasm may suffer from lethal arrhythmia, including advanced AV block, ventricular tachycardia or fibrillation, or even sudden death, and they are often resistant to conventional medical therapy including Ca-channel blockers (CCBs). Endothelial nitric oxide (NO) activity is reduced and markers of oxidative stress are elevated in patients with coronary spasm. Thrombogenesis is enhanced and plasma levels of hsCRP and P-selection are elevated in patients with coronary spasm. Thus, patients with coronary spasm have endothelial dysfunction and are suffering from a low-grade chronic inflammation. Polymorphisms of endothelial NO synthase, smoking, and low-grade inflammation are the most important risk factors for coronary spasm. Coronary spasm is a hyper-contraction of coronary smooth muscle triggered by an increase of intracellular Ca2+ in the presence of an increased Ca2+ sensitivity. It has been shown that RhoA/ROCK pathway is involved in Ca2+ sensitivity and that the reduced endothelial NO activity results in increased Ca2+ sensitivity through enhanced RhoA/ROCK pathway. Accordingly, it is possible that in addition to CCBs, RhoA/ROCK pathway blockers may prove to be useful for the treatment of coronary spasm.

    2015-01-01

    Primary hemifacial spasm (HFS) is a disorder that causes frequent involuntary contractions in the muscles on one side of the face, due to a blood vessel compressing the nerve at its root exit zone (REZ) from the brainstem. Numerous prospective and retrospective case series have confirmed the efficacy of microvascular decompression (MVD) of the facial nerve in patients with HFS. However, while MVD is effective, there are still significant postoperative complications. In this paper, recent technological advances related to MVD (such as lateral spread response, brainstem auditory evokes potential, three dimensional time of flight magnetic resonance angiography, intraoperative neuroendoscopy) are reviewed for the purposes of improving MVD treatment efficacy and reducing postoperative complications.

    Full Text Available El traumatismo torácico es una entidad patológica emergente, relacionada con accidentes automovilísticos. La lesión más frecuente es la fractura costal. Dependiendo de su gravedad, éste puede provocar tórax volante, contusión cardíaca, lesiones vasculares u otras alteraciones. La ruptura bronquial se observa ocasionalmente en traumatismos torácicos cerrados, y por lo general tiene lugar en el tronco principal del árbol tráqueo-bronquial. Su diagnóstico y manejo inicial representan un problema mayor. Los signos clásicos son la persistencia de neumotórax y flujo masivo de aire a través del drenaje torácico; sin embargo también hay casos que no son típicos. Es difícil determinar el momento correcto para iniciar la ventilación mecánica con presión positiva, la que puede aumentar gravemente el flujo de aire a través de la ruptura bronquial y acentuar el neumotórax a tensión. Presentamos el caso de un hombre de 25 años con un traumatismo torácico cerrado, causado por un accidente de automóvil, en quien la broncoscopía demostró una fractura del bronquio lobar medio. Comprobamos en este paciente, que la fibrobroncoscopía es el procedimiento más útil tanto en el diagnóstico, como en el tratamiento inicial y en el seguimiento post operatorio de su fractura bronquiaThoracic trauma is an emerging pathology related to the increase of motor vehicle accidents. Rib fracture is the most frequent injury; depending on the severity of the event it may be associated with flail chest, cardiac contusion, vascular lesions and other injuries. Bronchial rupture is occasionally seen in blunt trauma and it occurs mostly in the main stem of the tracheobronchial tree. It represents a great task in diagnosis and initial management. Persistent pneumothorax and massive airflow by the thoracic drain are the classic signs, however other cases are not so typical. The right moment to begin positive pressure ventilation is challenging, because in

    Massive hemoptysis is one of the most dreaded of all respiratory emergencies and can have a variety of underlying causes. It is mostly caused by bleeding from bronchial circulation. Bronchial artery embolization is now considered to be the treatment of choice for acute massive hemoptysis. Bronchial artery embolization (BAE) is a safe and effective nonsurgical treatment for patients with massive hemoptysis. However, nonbronchial systemic arteries can be a significant source of massive hemoptysis and a cause of recurrence after successful BAE. So knowledge of the bronchial artery anatomy, together with an understanding of the pathophysiologic features of massive hemoptysis, are essential for planning and performing BAE in affected patients. In addition, interventional radiologists should be familiar with the techniques, results, efficacy, safety and possible complications of BAE and with the characteristics of the various embolic agents. Bronchial arterial catheterisation in human via a percutaneous approach has been practiced for 32 years (1973) in the world and 20 years (1986) in China, initially for direct chemotherapy treatment for bronchial malignancies and then for the embolization of patients with massive haemoptysis. A review of clinical experience to evaluate technique,embolic materials,outcome and complications of BAE is presented.

    Pharmacological spasm provocation tests are invasive methods and we always have the potential to encounter complications when performing these tests. In 1980, Buxton et al. reported three deaths when they performed intravenous ergonovine testing. However, we now employ the intracoronary ergonovine test instead of the intravenous injection of ergonovine from a safety procedure point of view. Past serious major complications of intravenous ergonovine tests, intracoronary ergonovine tests, and intracoronary acetylcholine tests were 0.31% (26/8419), 0.51% (11/2173), and 0.95% (148/15,527), respectively. Selective intracoronary testing had the serious major complications in 0.89% of patients including just one death (0.006%) and two acute myocardial infarctions (0.01%). Selective spasm provocation tests had no additional risks compared with performing diagnostic coronary angiography alone. In the Western countries, the pharmacological spasm provocation tests are not familiar in the clinic except for some specialized institutions. We need international clinical studies using the same protocol of spasm provocation tests to compare the frequency, clinical features, and prognosis of acetylcholine- or ergonovine-provoked coronary spasm between Western and Asian countries. And we hope that Western guidelines give spasm provocation testing a class I indication similar to Japanese Circulation Society guidelines because coronary artery spasm may have fewer racial differences and borders.

    This report describes the rare case of a 27-year-old female patient with conversion disorder who presented unilateral ptosis with ipsilateral muscle spasm of orbicular oculi. The co-existing of ptosis and muscle spasm of orbicular oculi indicates that, in accord with prior reports, the overactivity of orbicular oculi is essential in psychogenic pseudoptosis. The co-existing of unilateral ptosis and ipsilateral muscle spasm of orbicular oculi in the present case leads us to the conclusion that the overactivity of orbicular oculi is essential in psychogenic pseudoptosis.

    Hemimasticatory spasm is a rare disorder characterized by paroxysmal involuntary contraction of the jaw-closing muscles. As the ideology and pathogenesis of the disease are still unclear, there has been no treatment that could give rise to a good outcome so far. Herein, we tried to use surgical management to cure the disease. Six patients with the disease were included in this study. These patients underwent microvascular decompression of the motor fibers of the trigeminal root. After the operation, all faces of the patients felt relaxed at varied degrees, except for 1 patient. Our study showed that microvascular decompression of the trigeminal nerve could lead to a better outcome. However, a control study with a large sample is needed before this technique is widely used.

    A close anatomical and functional relationship between superior and inferior airways is well documented. A typical example is offered by the close relationship between allergic rhinitis and asthma whose close connection is documented by epidemiological and pathological data. The mechanisms which can explain this phenomenon are not fully known but naso-bronchial reflexes, mouth-breathing due to nasal obstruction and aspiration of nasal secretions seem all to be important. Moreover it has been recently proved that the treatment of rhinitis can improve the concomitant asthma thus confirming their relationship. Another less frequent association is between sinusitis and asthma. Such a connection seems to be frequent in patients suffering of atopic rhinitis but also in patients presenting a nasal obstruction of different nature such as deviations of the nasal septum, adenoid hypertrophy etc. Also in this case a correct medical or surgical treatment of sinusitis can improve asthma symptomathology. Finally a classic example of involvement of superior and inferior airways is represented by the syndrome of ASA intolerance. These patients in fact initially complain of rhinitis which afterwards is complicated by the onset of nasal polyposis and asthma which can prove clinically very severe. Nowadays, anyway, there is no evidence that the treatment of rhinitis or polypectomy can improve the clinical course of asthma. In conclusion, diseases of superior and inferior airways must be considered in strict connection and need the same global treatment.

    We present the case of a Japanese male infant with Alexander disease who developed infantile spasms at 8 months of age. The patient had a cluster of partial seizures at 4 months of age. He presented with mild general hypotonia and developmental delay. Macrocephaly was not observed. Brain magnetic resonance imaging (MRI) findings fulfilled all MRI-based criteria for the diagnosis of Alexander disease and revealed mild atrophy of the dorsal pons and medulla oblongata with abnormal intensities. DNA analysis disclosed a novel heterozygous missense mutation (c.1154 C>T, p.S385F) in the glial fibrillary acidic protein gene. At 8 months of age, tonic spasms occurred, and electroencephalography (EEG) revealed hypsarrhythmia. Lamotrigine effectively controlled the infantile spasms and improved the abnormal EEG findings. Although most patients with infantile Alexander disease have epilepsy, infantile spasms are rare. This comorbid condition may be associated with the distribution of the brain lesions and the age at onset of Alexander disease.

    Hemifacial spasm (HFS) is a peripherally-induced movement disorder characterized by the involuntary, unilateral, intermittent, irregular, tonic or clonic contractions of muscles innervated by the ipsilateral facial nerve. Kindling-like hyperactivity of the facial nucleus induced by constant stimulation of compressing artery is considered as the predominant mechanism underlying the pathogenesis of HFS. As a treatment for HFS, microsurgical decompression and botulinum toxin injection have been shown to be highly successful. Anticonvulsant drugs relieve HFS in some patients; however, the use of such drugs is limited owing to their side effects, predominantly in elderly patients. We experienced two elderly HFS patients who exhibited a marked response to levetiracetam (LEV) without side effects. Although the exact underlying pharmacological mechanism remains unknown, we assume anti-kindling effect as one of the important pharmacological mechanism underlying the effect of LEV against HFS. Moreover, LEV is considered to be suitable for use in elderly patients because of its good tolerability. In addition, the lack of hepatic induction or inhibition makes it an easy and safe drug when used in addition to other anticonvulsants. Although the long-term benefit remains unknown, LEV may represent an alternative treatment for elderly HFS patients who are unable to undergo or decline surgical intervention and/or botulinum toxin injections or are intolerant to other anticonvulsants.

    Full Text Available Hemifacial Spasm (HS occurs idiopathically or secondary to the lesions compressing the root exit zone of the facial nerve symptomatically. Symptomatic HS is generally due to vascular compression. We report on a 23-year-old male with right sided HS for a month. Magnetic resonance imaging (MRI of the brain revealed a well-demarcated epidermoid cyst in the right cerebellopontine cistern. It was hypointense on T1-weighted imaging, hyperintense on T2-weighted imaging without contrast enhancement, hyperintense on DWI, and slightly hypointense on ADC relative to the brain. Although it caused shifting of the pons and medulla to the left side and compression of the right cerebellar peduncles and fourth ventricle, the sole symptom of the patient was HS. Clinicians are advised to request MRI/scan for brainstem lesions from the patients with HS. Epidermoid cysts in cerebellopontine cistern may present with HS as the sole symptom.

    Angiographic studies have shown that coronary artery spasm can be induced with ergonovine maleate. Coronary artery spasm induced by ergonovine maleate in these studies was nearly always accompanied by chest pain and electrocardiographic changes of myocardial ischemia. This report demonstrates that coronary artery spasm induced by ergonovine maleate may be diagnosed by angiography in the absence of these signs or symptoms.

    2003-01-01

    Objective To investigate the role of coronary artery spasm in the etiology of chest pain lacking significant coronary stenosis and to identify the clinical risk factors related to coronary artery spasm. Methods Two hundred and seventy five patients with chest pain, but without significant coronary artery stenosis underwent the intracoronary acetylcholine test. Coronary artery spasm was diagnosed while coronary artery stenosis increased to 90% and was accompanied by the usual chest pain with or without ischemic changes on electrocardiogram. Logistic regression was employed to investigate the relationships between coronary artery spasm and sex, age, hypertension, diabetes mellitus, smoking, hyperlipidemia and results of electrocardiographic treadmill stress test. Left ventricular ejection fraction and end diastolic pressure were compared between spasm group and non-spasm group. Results Coronary artery spasm was detected in 103 out of 271 patients, a rate of 38%. Logistic regression analysis showed that smoking and hyperlipidemia increased the relative risk of coronary artery spasm 4.2 times and 2.3 times, respectively. There was a significantly negative relationship between diabetes mellitus and coronary artery spasm. Furthermore, there was no coronary artery spasm detected in left ventricular ejection fraction and end diastolic pressure. Conclusions Coronary artery spasm was one of the important etiological factors for patients with chest pain but no coronary artery stenosis. Smoking and hyperlipidemia were the main clinical risk factors for coronary artery spasm.

    In lung sound analysis, the narrower the airways are, the higher the frequency of breathing sounds is, and, if a patient has higher than normal breathing sounds, i.e., bronchial sounds, he or she may have airway narrowing or airway inflammation. It is sometimes difficult to detect subtle changes in lung sounds; therefore, we anticipate that automated analysis of lung sounds will be used to overcome these difficulties in the near future.

    1954-12-01

    Full Text Available Among 11 patients a complete cure was obtained in one case, a fair result in 4 cases, while in 6 cases the effect of the operation has only been temporary and full recurrence has taken place. Even if decompression has thus resulted in a few recoveries and improvements, the results in the majority of cases have been disappointing. Everything points to hemifacial spasm being due to a disorder of the lower motor neuron. Intracranial lesions in the vicinity of the facial nerve are known to have resulted in irritation and spasm. It may be perfectly true that the majority of cases of hemifacial spasm are due to a lesion, the nature of which may vary, in the Fallopian canal near the stylomastoid foramen, not least the postparalytic following Bell's palsy. But the disappointing results of decompression seems to indicate that at the time of operation irreparable damage to the nerve has in the majority of cases been already done. Consequently I gave up decompression in cases of hemifacial spasm some years ago. Good results from injections of alcohol into the nerve have been reported13 but I prefer selective sections of the branches to the muscles involved as described by German and Greenwood8.

    To investigate the efficacy of Gelfoam single use for the management of hemoptysis by analyzing patients with recurrence in embolized artery and other artery, respectively. Between 1992 and 2000, 131 patients (104 men and 27 women, mean age: 54.4 years) with hemoptysis underwent BAE using gelatin sponge only. After puncturing the femoral artery using the Seldinger method, angiographies of the thoracic aorta, the bronchial arteries, the intercostal arteries, and the systemic collaterals which were suspected of bleeding focus and embolization were performed. Gelfoam was used 1 x 3 mm and 2 x 3 mm or 2 x 5mm by the diameter of feeding arteries. The cumulative hemoptysis control rate and recurrence rate were analyzed from the previously embolized vessels. Hemoptysis were recurred among 34 of 131 patients. Twenty-two patients had a recurrence from the same vessels and 12 from the different ones. Using the Kaplan-Meier method, the cumulative hemoptysis control rate was obtained in the patients with a recurrence from the same vessels: 88.8% in 1 month, 79.9% in 1 year, and 77.3% in 2 year. The reasons for recurrences of the same lesions are as follows; due to the tortuosity of the vessel (n=3); partial embolization through the common trunk formation between bronchial and anterior spinal artery (n=3); by vessel spasms or autogenous thrombus (n=2); due to the contrast media hypersensitivity (n=1). These 9 patients were not treated successfully. In the remaining 13 cases, hemoptysis were recurred due to recanalization of embolized vessels. Among 161 procedure, complications consisted of fever (n=8), dyspnea (n=8), mild chest discomfort (n=7), lower back pain (n=1), and transient lower leg paralysis (n=1), which were improved within several days. There was no serious complication in this study. Bronchial artery embolization using Gelfoam alone maybe effective and safe to control hemoptysis.

    Epidural emphysema is an exceptional complication of bronchial asthma, revealed by an incidental finding in chest tomography. We report a case of a 21-year-old man admitted with asthma attack complicated by subcutaneous and mediastinal emphysema. Chest tomography confirmed the mediastinal emphysema and also revealed the epidural emphysema within the vertebral canal. Neurological examination was negative. The patient showed complete recovery 10days after the onset of symptoms. The epidural emphysema is a rare complication during asthma attacks. The benignity of this complication should not require a systematic chest tomography.

  4. A belated revelation: from gastroesophageal reflux derived asthma to laryngotracheal irritation even spasm

    The author has been inspired by the Global Evidence-Based Consensus for gastroesophageal reflux (GER),which put forward four extra-esophageal syndromes:reflux cough syndrome,reflux laryngitis syndrome,reflux dental erosion syndrome and the reflux asthma syndrome.The author himself happened to receive five emergency rescue treatments following apparent "bronchial asthma",which was to be diagnosed as GER at his own insistence.PPI resulted in some relief.After being rescued again from suffocation,he had a fundaplication,which was performed at the Englewood Hospital & Medical Center,Englewood,USA in March 2006.The procedure immediately cleared up his "asthma".A month later he brought forth a Center for GER in an army hospital in Beijing,China.Up to now,601 patients with mainly respiratory distress(84%)were treated by Stretta Radiofrequency,58 by surgery and more by PPI.The GER Center is now complete with a ward.GER patients with respiratory distresses turned out to fare better than those with acid regurgitation.A nozzle"shaped pharynx was found in patients with the reflux.Animal study revealed that the refluxate entered into trachea and even lungs.Gradually a hypothesis of a gastrooesophago-laryngo-tracheal reflux took shape.Our modest effort to treat GER-derived respiratory distresses has got off to an encouraging start amid relative shortage of experience and facilities.We would like to share two thoughts with scholars and experts at home and abroad:1.The GER-derived asthma is not asthma,but GER pure and simple;2.The pathogenesis of "asthma" is not asthma,but laryngotracheal irritation/spasm and its sequence.

    2012-01-01

    There is evidence that primary hemifacial spasm (HFS) in the majority of patients is related to a vascular compression of the facial nerve at its root exit zone (REZ). As a consequence, the hyperexcitability of facial nerve generates spasms of the facial muscles. Microvascular decompression (MVD) of the facial nerve near its REZ has been established as an effective treatment of HFS. Intra-operative disappearance of abnormal muscle responses (lateral spread) elicited by stimulating one of the facial nerve branches has been used as a method to predict MVD effectiveness. Other neurophysiologic techniques, such as facial F-wave, blink reflex and facial corticobulbar motor evoked potentials (FCoMEP), are feasible to intra-operatively study changes in excitability of the facial nerve and its nucleus during MVDs. Intra-operative neuromonitoring with the mentioned techniques allows a better understanding of HFS pathophysiology and helps to optimise the MVD.

    Pallister-Killian syndrome (PKS) is a rare, sporadic, genetic disorder characterized by dysmorphic features, learning disability, and epilepsy. It is caused by a mosaic supernumerary isochromosome 12p (i[12p]). The i(12p) is rarely found in peripheral blood but it is present in skin fibroblasts. Recognition is essential for cytogenetic diagnosis. We describe a male aged 2 years 6 months and a female aged 11 years with PKS and epileptic spasms (ES). This type of seizure is not unusual in patients with brain malformations and with severe developmental delay, but it is sometimes difficult to recognize without video-electroencephalogram studies and could be mistaken for other types of seizure or behavioural manifestations. In these two patients with PKS, spasms had late onset, persisted beyond infancy, and were drug resistant. Clinicians should be aware of this possibility in PKS, which appears to be a rare cause of ES.

    In this report we describe a 53-year-old woman with advanced non-small cell lung cancer, treated with pemetrexed and cisplatin combination therapy, followed by pemetrexed monotherapy. The patient developed severe muscle spasms at least twice, shortly after administration of pemetrexed monotherapy. A possible explanation for this observation is that in combination with cisplatin therapy, the patient was hyperhydrated before administration to promote renal excretion and reduce toxicity. Pemetrexed is also renally excreted, which supports the finding that toxicity did not occur when the patient was hyperhydrated. After discontinuation of pemetrexed the symptoms did not reoccur. All aspects of this case point to a possible relationship between pemetrexed and an adverse drug reaction (ADR). We conclude that muscle spasms are a rare, but possibly dose-related ADR of pemetrexed-based therapy. PMID:28203304

    Hemifacial spasm (HFS) is a common neurological disorder characterized by involuntary tonic and clonic contractions of the muscles innervated by the facial nerve. We aimed to describe clinical features, common antecedents, triggers and relieving factors in patients with hemifacial spasm to study the correlation of hypertension and HFS, and to compare clinical features of primary and secondary cases of HFS. The data for the study were collected prospectively on a predesigned and pre-tested format at the first attendance in all consecutive HFS patients attending the movement disorders clinic of a tertiary teaching hospital in India. The demographic profile, HFS symptoms, antecedent illnesses and neurological examination were recorded and analyzed. Muscle power in individual muscles innervated by the facial nerve was tested carefully before botulinum toxin injection. Hemifacial spasm occurred in 7.14% (n = 582) of 8,151 cases registered at the movement disorders clinic from 1993 to 2010. Data of 321 patients were complete and were included in the study. Females constituted 49.22% (n = 158). The mean age the patients was 46.02 ± 11.82 years; ipsilateral ear clicking was observed in 22.74% cases. The most common aggravating factor was stress (44.86%), while the most common relieving factor was sleep (44.24%). Two hundred fifty-two patients (78.5%) had primary HFS. The severity of spasm correlated significantly with disease duration (p muscles (p < 0.001). We did not observe any correlation between HFS on the left side and hypertension, as has been reported earlier. This is one of the largest studies of HFS patients and the only one that prospectively assesses patients with HFS clinically on their first visit. Interesting observations of this study are lack of female preponderance, presence of clicking in the ipsilateral ear and facial weakness even prior to botulinum toxin injection.

    Bimatoprost is a prostaglandin analogue used topically in the treatment of glaucoma. Commonly known side effects include eyelash growth, iris pigmentation and conjunctival hyperemia. While pseudomyopia is reported to be caused by parasympathomimetics, such an effect precipitated by bimatoprost has not yet been reported. We report a case demonstrating pseudomyopia and accommodative spasm caused after starting bimatoprost 0.03% in a young patient with glaucoma.

    2003-05-01

    We investigated trigemino-facial excitatory and inhibitory responses in perioral muscles in hemifacial spasm (HFS). We examined 15 patients affected with idiopathic HFS and 8 healthy controls. Five patients had spasms mostly limited to the periocular region and 10 had spasms also involving the perioral muscles. Responses were recorded from the resting orbicularis oculi (OOc), levator labii superioris (LLS) and orbicularis oris (OOr) muscles, after supraorbital (SO) nerve stimulation and during isolated voluntary contraction of LLS muscle. Eight patients showed complete or partial preservation of the late silent period (SP2) in activated LLS muscle. The remaining 7 patients showed absence of SP2. Early and late excitatory responses were variably present in LLS muscle at rest. Patients with HFS clinically restricted to periocular muscles had at least partial preservation of the SP2. In conclusion, in HFS patients inhibitory trigemino-facial reflexes are impaired and excitatory trigemino-facial responses are elicited in perioral muscles. These two phenomena seem to develop independently; the degree of trigemino-facial reflex impairment parallels the extension of involuntary movements to the lower facial muscles.

    Introduction Esophageal diverticulum, a relatively rare condition, has been considered to be associated with motor abnormalities such as conditions that cause a lack of coordination between the distal esophagus and lower esophageal sphincter. Presentation of case We herein report a case of esophageal epiphrenic diverticulum associated with diffuse esophageal spasm. A 73-year-old woman presented with dysphagia and regurgitation. Imaging examinations revealed a right-sided esophageal diverticulum located about 10 cm above the esophagogastric junction. High-resolution manometry revealed normal esophageal motility. However, 24-h pH monitoring revealed continuous acidity due to pooling of residue in the diverticulum. An esophageal epiphrenic diverticulum was diagnosed and resected thoracoscopically. Her dysphagia recurred 2 years later. High-resolution manometry revealed diffuse esophageal spasm. Discussion The diverticulum in the present case was considered to have been associated with diffuse esophageal spasm. The motility disorder was likely not identified at the first evaluation. Conclusion In this case, the patient’s symptoms spontaneously resolved without any treatment; however, longer-term follow-up is needed. PMID:26143577

    A 35-year-old female with a known medical history of cystic fibrosis was admitted to our institution for massive hemoptysis. CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

    Ductal spasm is a rare yet important complication of device occlusions of patent ductus arteriosus. Spasm may result in failure of the procedure, under-sizing of the device, or embolisation of the implanted device as the spasm resolves after the procedure. We describe a novel protocol that rapidly and completely reversed the spasm in eight prematurely born infants who experienced ductal spasm during cardiac catheterisations for patent ductus arteriosus occlusion. In total, eight infants born between 25 and 34 weeks of gestation presented for transcatheter patent ductus arteriosus occlusion between 13 and 87 months of age. All eight patients experienced ductal spasm either immediately before, during, or soon after induction of anaesthesia or only after entering the ductus arteriosus with a catheter. After detection of the spasm, the anaesthetist, in each case, changed the mode of anaesthesia from inhaled sevoflurane to total intravenous anaesthesia with propofol, reduced the inhaled oxygen fraction to 21%, and initiated a continuous intravenous infusion of prostaglandin E1. The first two steps (total intravenous anaesthesia and FiO2 0.21) resulted in only partial relaxation of the spasm. Complete relaxation was attained after intravenous prostaglandin E1 infusions of only 10-15 minutes' duration. While maintaining this protocol, six ducti were successfully occluded and two were considered to be unsuitable for device occlusion and were referred for surgery. Ductal spasm during transcatheter occlusion may be reliably resolved and the procedure safely completed by a simple anaesthetic protocol, including the continuous infusion of intravenous prostaglandin E1.

    Spinal cord injured (SCI) individuals may be afflicted by spasticity, a condition in which involuntary muscle spasms are common. EMG recordings can be analyzed to quantify this symptom of spasticity but manual identification and classification of spasms are time consuming. Here, an algorithm was created to find and classify spasm events automatically within 24-h recordings of EMG. The algorithm used expert rules and time-frequency techniques to classify spasm events as tonic, unit, or clonus spasms. A companion graphical user interface (GUI) program was also built to verify and correct the results of the automatic algorithm or manually defined events. Eight channel EMG recordings were made from seven different SCI subjects. The algorithm was able to correctly identify an average (±SD) of 94.5 ± 3.6% spasm events and correctly classify 91.6 ± 1.9% of spasm events, with an accuracy of 61.7 ± 16.2%. The accuracy improved to 85.5 ± 5.9% and the false positive rate decreased to 7.1 ± 7.3%, respectively, if noise events between spasms were removed. On average, the algorithm was more than 11 times faster than manual analysis. Use of both the algorithm and the GUI program provide a powerful tool for characterizing muscle spasms in 24-h EMG recordings, information which is important for clinical management of spasticity.

    Background The aim of this study is to discuss video-assisted thoracic surgery (VATS) sleeve bronchial lobectomy when handling the locally advanced central lung cancer (involving the trachea and/or main bronchus). Methods A 2.5 cm × 1.0 cm mass was found in the right upper lobe. Bronchoscopy demonstrated the tumor obstructing the right upper lobe bronchus and involved the right main bronchus and bronchus intermedius. Interrupted sutures were chosen for bronchial anastomosis. Bronchial membrane was sutured first, and then circumference end-to-end anastomoses were carried out using 3-0 absorbable sutures. Results There were no complications and the patient was discharged 8 days postoperatively. Conclusions The third intercostal space of the anterior axillary line was suggested for right upper lobe bronchial sleeve resection. This incision can reduce the distance and angle between the anastomosis to the incision, and facilitate anastomosis. This approach can also prevent operator from fatigue for keeping one posture for a long time. Clearance of the mediastinal lymph nodes before cutting the bronchus was helpful for exposing the right main bronchus, the upper lobe bronchus and bronchus intermedius satisfied. And this option would avoid pulling bronchial anastomosis during mediastinal lymph nodes clearance. Interrupted suture was safe and effective for VATS bronchial anastomosis. PMID:27621889

    OBJECTIVE: To summarize the development of electroacupuncture stimulation in the treatment of stroke-induced limb spasm, to provide research possibilities or clinical development, and to clarify the mechanism and therapeutic effects of electroacupuncture stimulation. DATA SOURCES: Articles relating to therapeutic effects of electroacupuncture stimulation on treatment of stroke-induced limb spasm, as well as clinical studies (which are not limited to age, sex and race), were retrieved from the China Journal Fulltext Database from January 2000 to December 2007. The key words were stroke, apoplexy, spasm, and electroacupuncture in Chinese. Other articles were obtained from specific journals or books.STUDY SELECTION: Data were first selected by title and abstract. Clinical and rehabilitative studies relating to the effects of electroacupuncture and acupuncture on the treatment of stroke-induced limb spasm were included. Clinical studies related to the rehabilitative treatment of limb spasm were excluded, unless the effects of electroacupuncture stimulation were recorded. DATA EXTRACTION: A total of 338 references were collected; however, 295 of these were excluded. Therefore, 43 articles were analyzed, comprising 40 in Chinese and 3 in English.DATA SYNTHESIS: At present, acupuncture is widely used at home to treat stroke-induced limb spasm; however, acupuncture at different acupoints might cause different clinical effects. Electroacupuncture, which is characterized by analgesia and relief of spasm, can preclude inflammatory edema, improve blood circulation and blood viscosity, inhibit platelet aggregation and adherence, relieve formation of atheromatous plaque in tunica intima of artery, and resist cerebral anoxia, so as to relieve stroke-induced limb spasm. Meanwhile, electroacupuncture combined with rehabilitation can effectively decrease the degree of spasm and improve motor function. CONCLUSION: Acupuncture and moxibustion therapy are superior in the rehabilitative

    Full Text Available This study demonstrates that an adrenergic mechanism plays an important role in producing the delayed cerebral vasospasm which follows subarachnoid hemorrhage. Results were as follows: 1. Experimental subarachnoid hemorrhage (SAH was produced by injection of fresh arterial blood into the cisterna magna in cats. The cerebral vasospasm was shown angiographically to be biphasic in nature: immediate constriction lasting 1 h and marked prolonged spasm occurring between the 3rd and 5th day after SAH. The amount of noradrenaline (NA and dopamine-beta-hydroxylase (DBH activity decreased over a period of 24 h both within the wall of the basilar artery and in the locus ceruleus and then gradually increased, reaching a maximum on the 3rd day after SAH. 2. Topical application of spasmogenic substances (NA and blood produced a marked constriction of the hypersensitive basilar artery on the 3rd day after SAH. 3. 6-Hydroxydopamine (6-OHDA injection into the cisterna magna produced prolonged vasocilatation. The dilated vessel responded with mild transient constriction after the topical application of NA or fresh blood. DBH activity and NA concentration in the vessels, locus ceruleus and medial hypothalamus decreased markedly on the 3rd day after the cisternal injection of 6-OHDA. 4. Various spasmogenic substances (i.e. serotonin, NA, prostaglandins and methemoglobin were measured in a mixture of equal volume of CSF and blood in cats. ONly the serotonin in the mixed fluid produced vasoconstriction. Spasmogenic substances decreased markedly in the mixed fluid incubated for 3 days at 37 degrees C, and none of these substances apart from methemoglobin was present in a concentration sufficient to produce constriction of vessels. 5. These results suggest that early spasm is induced by serotonin around the arteries of the cranial base, and delayed spasm might be caused by hyperreaction of cerebral vessels to spasmogenic substances such as methemoglobin, during the

In doing so, he accurately described the clinical hallmarks of a condition that we recognize as Bell palsy.

    Diffuse coronary vasospasm is an unpredictable and serious complication following coronary artery bypass surgery. The treatment of this emergency is dependent on patient suitability for angiography and direct injection of vasodilators into the affected vessels. In patients unable to proceed to angiography the diagnosis can only be suspected but treatment is nevertheless still towards reinstitution of coronary blood flow. We present one such case in which re-grafting and extracorporeal membranous oxygenation proved successful in restoring cardiac function in a patient with diffuse coronary artery spasm.

    The intimate anatomical relationship of the facial nerve to the parotid parenchyma has a significant influence on the presenting signs and symptoms, diagnosis and treatment of parotid neoplasms. However, to our knowledge, hyperactivity of this nerve, presenting as facial spasm, has never been described as the presenting sign or symptom of a parotid malignancy. We report a case of carcinoma arising in a recurrent pleomorphic adenoma of the left parotid gland (i.e., carcinoma ex pleomorphic adenoma) that presented with hemifacial spasms. We outline the differential diagnosis of hemifacial spasm as well as a proposed pathophysiology. Facial paralysis, lymph node enlargement, skin involvement, and pain have all been associated with parotid malignancies. To date the development of facial spasm has not been reported with parotid malignancies. The most common etiologies for hemifacial spasm are vascular compression of the ipsilateral facial nerve at the cerebellopontine angle (termed primary or idiopathic) (62%), hereditary (2%), secondary to Bell’s palsy or facial nerve injury (17%), and hemifacial spasm mimickers (psychogenic, tics, dystonia, myoclonus, myokymia, myorthythmia, and hemimasticatory spasm) (17%). Hemifacial spasm has not been reported in association with a malignant parotid tumor but must be considered in the differential diagnosis of this presenting symptom. PMID:28246588

    Vascular spasm is a poorly understood but critical biomedical process because it can acutely reduce blood supply and tissue oxygenation. Cardiomyopathy in mice lacking gamma-sarcoglycan or delta-sarcoglycan is characterized by focal damage. In the heart, sarcoglycan gene mutations produce regional defects in membrane permeability and focal degeneration, and it was hypothesized that vascular spasm was responsible for this focal necrosis. Supporting this notion, vascular spasm was noted in coronary arteries, and disruption of the sarcoglycan complex was observed in vascular smooth muscle providing a molecular mechanism for spasm. Using a transgene rescue strategy in the background of sarcoglycan-null mice, we replaced cardiomyocyte sarcoglycan expression. Cardiomyocyte-specific sarcoglycan expression was sufficient to correct cardiac focal degeneration. Intriguingly, successful restoration of the cardiomyocyte sarcoglycan complex also eliminated coronary artery vascular spasm, while restoration of smooth muscle sarcoglycan in the background of sarcoglycan-null alleles did not. This mechanism, whereby tissue damage leads to vascular spasm, can be partially corrected by NO synthase inhibitors. Therefore, we propose that cytokine release from damaged cardiomyocytes can feed back to produce vascular spasm. Moreover, vascular spasm feeds forward to produce additional cardiac damage.

Bronchial asthma--heterogeneous disease by both etiology and clinical characteristics. At the same time genetic prognosis is based on the unity of pathogenetic mechanisms of development, though in immunological reactions that are the base of this disease, alternative variants are possible. The aim of this review is carrying out parallels between modern achievements in the field of deciphering trigger mechanisms of bronchial asthma pathogenesis and object of genetic studies based on these mechanisms. Among the examined conceptions--role of epithelial tissue in trigger mechanisms of bronchial asthma, variants of key role of immune system cells, first of all, T-helpers of various types for further development of inflammatory-effector reactions with damage characteristic for this disease. Compliance of contemporary approaches of genetic studies and novel concepts of bronchial asthma pathogenesis is shown.

    The pathophysiologic basis of hemifacial spasm is abnormal cross-transmission between facial nerve fibers. The author hypothesized that the demyelinated facial nerve fibers were connected with the sympathetic nerve fibers on the offending artery wall, and thus the latter function as a bridge in the cross-transmission circuit. This hypothesis was tested using a rat model of hemifacial spasm. A facial muscle response was recorded while the offending artery wall was electrically stimulated. The nerve fibers on the offending artery wall were blocked with lidocaine, or the superior cervical ganglion, which innervates the offending artery, was resected, and meanwhile the abnormal muscle response was monitored and analyzed. A waveform was recorded from the facial muscle when the offending artery wall was stimulated, named as "Z-L response". The latency of Z-L response was different from that of abnormal muscle response. When the nerve fibers on the offending artery wall were blocked by lidocaine, the abnormal muscle response disappeared gradually and recovered in 2h. The abnormal muscle response disappeared permanently after the sympathetic ganglion was resected. Our findings indicate that cross-transmission between the facial nerve fibers is bridged by the nerve fibers on the offending artery wall, probably sympathetic nerve fibers.

    Hemimasticatory spasm is a rare cranial nerve disorder, which is characterized by paroxysmal involuntary contraction of one or more unilateral jaw-closing muscles. It is induced by movement of the mouth and accompanied by progressive facial hemiatrophy or localized scleroderma, Until now, only 26 patients who were demonstrated definitely by electrorayography have been reported in the world. Although there has been considerable speculation regarding the mechanism that results in hemimasticatory spasm, none of them could provide reasonable hypothesis to explain all the aspects of the disease successfully. The specific mechanism of the disease has not been understood by now. In the recent paper, with a literature we reviewed the literature comprehensively, the etiology, diagnosis and treatment as well as mechanism of the disease were analyzed as well.%咀嚼肌痉挛是一种临床罕见疾病,表现为单侧嚼肌突发阵发性、不自主地抽搐发作.伴或不伴有单侧面萎缩或局部硬皮病,其发病机制至今尚不明确,国内外报道极少,目前为止,仅26例具有肌电图支持的病例报道.文章复习了相关文献,对其病因、发病机制、诊断原则、治疗方法等作了系统综述.

    Full Text Available Introduction & objective: One of the most important drawbacks of radial artery is its tendency toward spasm and one of the rare etiologies of that is recurrent blood sampling of the artery. Other causes are injection of drugs in artery in spite of vein, or using radial artery in cardiopulmonary bypass. Papaverine is a useful drug in vasospasm, but it must be used with special caution to avoid it's complications such as arrhythmia. Case: The patient was a 72 year old man with intestinal gangrene and peritonitis whom was operated in Al-Zahra hospital in 2008. During Laparatomy surgery, because of severe acidosis, blood sampling was done 3 times for blood gas analysis. After being taken to the recovery ward, no radial pulse was detectable in the patient's right hand and severe cyanosis in the same hand was seen. After inserting the arterial catheter in brachial artery, treatment with Papaverine, indications of recovery were seen. Conclusion: Despite the rarity of radial artery spasm during anesthesia, it is very dangerous situation, and anesthesiologist must try to prohibit and be able to manage this problem and have suitable drugs in the operation room.

    Full Text Available Bronchial atresia is a rare pulmonary developmental anomaly characterized by the presence of a focal obliteration of a segmental or lobar bronchial lumen. The lung distal to the atretic bronchus is typically emphysematous along with the presence of mucus filled ectatic bronchi (mucoceles. BA is usually asymptomatic but pulmonary infections can rarely develop in the emphysematous lung distal to the atretic bronchus. We present a unique case of chronic pulmonary aspergillosis (CPA in a patient with BA with no evidence of immune dysfunction. The patient was treated initially with voriconazole and subsequently underwent surgical excision of the involved area. On follow-up, she has done extremely well with no evidence for recurrence. In summary, we describe the first case of chronic pulmonary aspergillosis in an immunocompetent patient with bronchial atresia.

    Full Text Available Introduction. Bronchial hyperresponsiveness (BHR is a factor in predicting bronchial asthma independently of inflammation markers. Objective. The aims were to determine the frequency and important predictive facts of BHR and the effect of prophylaxis by Global Initiative for Asthma (GINA and National Asthma Education and Prevention Program (NAEPP on BHR in asthmatic children. Methods. BHR in 106 children was evaluated by the bronchoprovocation test with methacholine. Results. The prevalence rate of symptomatic BHR is 18% for crucial point of PC20=4.1±3.03 mg/ml and PD20=3.22±2.59 μmol methacholine. On average asthmatic children express moderate BHR, which persists even two years after administering prophylaxis. After two years bronchial reactivity is significantly smaller, the change of FEV1 is significantly smaller, the velocity of change of slope dose response curve (sDRC is faster and the provocative concentration of methacholine that causes wheezing is 2-3 times lower. A mild sDRC shows milder bronchoconstriction after two years. The fast change of bronchial reactivity in 41% of asthmatic children is contributed to aero-pollution with sulfur dioxide and/ or, possible insufficient and/or inadequate treatment during two years of administering prophylaxis. A simultaneous effect of allergens from home environment and grass and tree pollens and of excessive aero-pollution on children’s airways is important in the onset of symptomatic BHR. After two years of treatment by GINA and NAEPP children do not show asthma symptoms or show mild asthma symptoms, however bronchial sensitivity remains unchanged. Conclusion. Optimal duration of anti-inflammatory treatment in asthmatic children who show moderate bronchial hyperresponsiveness should be longer than two years.

    @@ Bronchial asthma is a disease with reversible tracheospasm and tracheostenosis due to excessively increased tracheal-bronchial reactivity induced by sensitinogen or non-sensitinogen. Although its etiology is complicated, the disease is generally caused by internal injury resulting from accumulation of phlegm in the lungs, damage to the spleen by improper diet and impairment of the kidneys by overstrain and excessive coitus;or it can be caused by six exogenous pathogenic factors, with obstruction of the airways by phlegm and upward adverse flow of the lung-qi.

    Variant angina is a form of angina pectoris that shows transient ST-segment elevation on electrocardiogram during an attack of chest pain. Ischemic episodes of variant angina show circadian variation and often occur at rest from midnight to early morning. Ischemic episodes also occur during mild exercise in the early morning. However, they are not usually induced by strenuous exercise in the afternoon. Other important clinical features of variant angina include the high frequency of asymptomatic ischemic episodes and the syncope that sometimes occur during the ischemic episodes. Syncope is due to severe arrhythmias, including ventricular tachycardia, ventricular fibrillation, and high-degree atrioventricular block. Coronary artery spasm is the mechanism of ischemic episodes in variant angina. The incidence of coronary artery spasm shows a racial difference and is higher in Japanese than in Caucasians. Coronary arteriograms are normal or near-normal in most Japanese patients with variant angina. Deficient basal release of nitric oxide (NO) due to endothelial dysfunction, and enhanced vascular smooth muscle contractility with the involvement of the Rho/Rho-kinase pathway are reported to play important roles in the pathogenesis of coronary artery spasm. Other precipitating factors of coronary artery spasm include imbalance in autonomic nervous activity, increased oxidative stress, chronic low-grade inflammation, magnesium deficiency, and genetic susceptibility. The genetic risk factors associated with coronary artery spasm include gene polymorphisms of endothelial NO synthase (NOS), paraoxonase, and other genes. Calcium channel blockers are extremely effective in preventing coronary spasm. The long-acting nitrate, nicorandil, and Rho-kinase inhibitor are also useful for inhibiting coronary artery spasm. Because variant angina can lead to acute myocardial infarction, fatal arrhythmias, and sudden death, early treatment is important. The prognosis of patients with

    Recently excellent results have been reported with microvascular decompression in cases of trigeminal neuralgia (TN) and hemifacial spasm (HFS). The neuroradiological diagnosis of TN and HFS. however, is not satisfactory. As a trial, we performed metrizamide CT cisternography (MCT) or gas CT cisternography (GCT) in order to reveal the nerve and the adjacent structures in the cisternal portion for preoperative diagnosis. MCT was performed in two patients with TN and in two patients with HFS, while GCT was performed in three patients with TN and in two patients with HFS. One case with TN was examined by both MCT and GCT. Therefore, the diagnostic value of MCT and GCT in TN or HFS has been evaluated in nine examinations in eight cases. MCT and GCT are both useful in delineating the trigeminal nerve, the facial nerve, and the adjacent arteries. Therefore, it is possible thus to diagnose the vascular compressing point and the offending artery in patients with TN and HFS.

    We presented a case of anomalous single-coronary artery detected incidentally during routine coronary angiography. A 32-year-old male Chinese patient presented with recurrent pre-syncope and six episodes of syncope. Coronary angiography and coronary-computed tomography (CT)-angiography performed by a dual-source computed tomography (DSCT) revealed that the patient had a single large right coronary artery. A moderately large branch originated from the proximal part of the single right coronary artery and extended to the left, passing the anterior to the pulmonary artery, and divided into the anterior descending artery branch and circumflex branch at the base of the left auricular appendage. The episodes of the syncope were suspected to be caused by coronary arterial spasm, so this patient was on a regimen of 30 mg of diltiazem every 6 h and had no recurrence of syncope during follow-up.

    The purpose of this study was to evaluate the prevalence and type of lung function disorders in Danish farmers. Three samples of farmers were drawn from a group of unselected farmers who had participated in an epidemiological study. Group I (47 persons) was a sample of the 8% of all farmers who had reported that they had asthma; group II (63 persons) was a sample of the 28% of farmers who had had wheezing, shortness of breath, or cough without phlegm; and group III (34 persons) a sample of the farmers (64% of the total) who had no asthma and no respiratory symptoms. The farmers with symptoms (groups I and II) had low mean levels of FEV1 and high values for residual volume, whereas the symptomless farmers had normal lung function and no airways obstruction. The proportion of farmers with an FEV1 below the 95% confidence limit for predicted values was 43% in group I and 23% in group II; there were none in group III. Bronchial hyperreactivity to histamine occurred in 96% of asthmatic farmers, 67% of farmers with wheezing or shortness of breath, and 59% of symptomless farmers. A low level of FEV1 was associated with the number of years in pig farming and bronchial hyperreactivity in group II but not group I or III. Most of the bronchial hyperreactivity was explained in the multiple regression analysis by a low FEV1, though this was significant only for farmers in group II. Thus farmers who reported asthma, wheezing, shortness of breath, or a dry cough in general had airways obstruction with an increased residual volume, whereas symptomless farmers had normal lung function. Severe bronchial hyperreactivity was mostly explained by a diagnosis of asthma and poor lung function, though some farmers with normal lung function and no respiratory symptoms had increased bronchial reactivity.

    Full Text Available Parry-Romberg syndrome (PRS with hemimasticatory spasm (HMS is quite an uncommon overlapping phenomenon which very often mimics jaw closing dystonia. A previously healthy 35-year-old female, during her 5 th month of pregnancy started developing intermittent unilateral painful spasms of jaw while conversation, clinching of teeth, or eating, which led to frequent tongue bites. The spasms were worsened during pregnancy. She used to do certain manoeuvre like sensory tricks in form of touching involved side of the face to relieve the symptoms. Apart from this, she developed progressive hemifacial and hemitongue atrophy. Other medical and neurological examinations were normal. Laboratory investigations as well as neuroimaging were noncontributory. The spasm responded to carbamazepine but hemifacial atrophy persists. To our best knowledge, onset and worsening of this syndrome in pregnancy has not been described earlier which might be correlated either with some hormonal imbalance or some unknown mechanisms.

    Young's Modulus and dynamic force moduli were measured on human bronchial airway tissues by compression. A simple and low-cost system for measuring the tensile-strengh of soft bio-materials has been built for this study. The force-distance measurements were undertaken on the dissected bronchial airway walls, cartilages and mucosa from the surgery-removed lungs donated by lung cancer patients with COPD. Young's modulus is estimated from the initial slope of unloading force-displacement curve and the dynamic force moduli (storage and loss) are measured at low frequency (from 3 to 45 Hz). All the samples were preserved in the PBS solution at room temperature and the measurements were perfomed within 4 hours after surgery. Young's modulus of the human bronchial airway walls are fond ranged between 0.17 and 1.65 MPa, ranged between 0.25 to 1.96 MPa for cartilages, and between 0.02 to 0.28 MPa for mucosa. The storage modulus are found varying 0.10 MPa with frequency while the loss modulus are found increasing from ...

    Meteorism, abdominal spasms, diarrhea, casually obstipation, flatulence and nausea are symptoms of fructose malabsorption (FIT) and/or lactose intolerance (LIT), but are also symptoms of irritable bowel syndrome (IBS). Therefore these diseases should be considered primarily in patients with digestive complaints. For diagnosis an H(2)-breath test is used.In 1,935 patients (526 m, 1,409 f) a fructose intolerance test and in 1,739 patients (518 m,1,221 f) a lactose intolerance test was done.FIT is found more frequently than LIT (57 versus 52 % in adults (p intolerance (HIT). Headache (ca. 10 %), fatigue (ca. 5 %) and dizziness (ca. 3 %) may occur after the test, irrespective whether the test was positive or negative.In more than 2/3 of patients a diet reduced in fructose or lactose may lead to improvement or remission of these metabolic disorders. IBS, which is often correlated with FIT (183/221 patients = 83 %), can be improved by relevant but also not relevant diets indicating that irritable bowel disease seems to be caused primarily by psychological disorders.

    The relationship between hypertension and hemifacial spasm (HFS) has been debated. Microvascular decompression surgery is effective in some HFS patients with uncontrolled hypertension. To address current gaps in knowledge, we conducted a meta-analysis of case-control studies that have examined the prevalence of hypertension in HFS patients compared to non-HFS controls. We also evaluated the implications and limitations of the pooled studies. We identified 62 studies from PubMed, The Cochrane Library, Web of Science and Scholar.google.com and six studies that fit our inclusion criteria were included. A random-effects model was used to derive the pooled estimate of the Odds Ratio. The data was plotted on a Forest plot. A pooled analysis involving 51585 subjects, 549 cases, 720 neurological controls and 50316 controls from the general population, showed that HFS patients had a higher chance of developing hypertension (OR = 1.72, 95% CI = (1.12, 2.31), p-value  <0.001). The prevalence of hypertension was higher in HFS patients as compared to non-HFS patients. This meta-analysis highlights a positive correlation between hypertension and HFS. Blood pressure should be closely monitored during the follow-up of HFS patients. Preliminary links between ventrolateral medullary (VLM) compression and HFS should be further evaluated in future studies.

    Magnetic resonance imaging (MRI) was performed on five patients with infantile spasms who were treated with relatively low doses of adrenocorticotrophic hormone (ACTH) to study the extent of brain shrinkage induced by ACTH therapy. MRI prior to ACTH therapy revealed periventricular hyperintensity (PVH) areas and poor myelination in four patients. In one case, MRI performed 2 days after initiation of ACTH therapy also showed PVH and poor myelination. Brain shrinkage was observed 2 weeks after initiation of ACTH therapy. The most impressive follow-up finding upon MRI was the decrease in PVH found in four patients. The differentiation between myelinated white matter and surrounding cortex became poorer in three cases. Cortical atrophy progressed in all patients but ventricular dilation progressed in only one patient. At the end of ACTH therapy, ventricular dilation progressed in all cases. These findings suggest that loss of water not only from periventricular white matter but also from cortex is the main etiological factor of brain shrinkage induced by ACTH.

    Current evaluation of radial artery spasm (RAS), a frequent finding during the transradial approach for coronary angiography and angioplasty (TRA), is subjective. A quantitative measure of RAS will help in evaluation and comparison of management strategies. The objectives of the study were to assess the feasibility and safety of using an automatic pullback device (APD) for removal of transradial introducer sheaths and to establish a parameter to quantify RAS. In 50 consecutive transradial procedures, the APD was used to measure the force required for sheath removal. The mean maximal pullback force (MPF) was 0.53 +/- 0.52 kg (range, 0.1-3.0 kg). In 48 (96%) cases, the MPF was reached within the first 5 sec of pullback. All patients with clinical RAS (n = 4) had an MPF greater than 1.0 kg, while the remaining had an MPF less than 1.0 kg. All patients with severe pain during sheath removal (n = 3) had an MPF greater than 1.0 kg, while no patient with an MPF less than 1.0 kg had severe pain. It is feasible and safe to remove transradial introducer sheaths using the APD. The MPF is achieved within the first 5 sec of pullback and is a reliable parameter to quantify RAS. An MPF more than 1.0 kg correlates with clinical RAS and is associated with severe pain during sheath removal.

    Objective: To discuss the mechanism of cerebral vessel spasm caused by concussion and the effect of Nimodipine on concussion. Methods: A total of 224 patients who were treated from March 1995 to October 1999 were divided into two groups randomly, ie, Nimodipine group (113 cases) and control group (111 cases). Middle cerebral artery (MCA), basilar artery (BA) and the average peak forward velocity of cerebral blood flow were observed by color three-dimensional transcranial Doppler (3D-TCD) within 24 hours after admission and at the end of 3-6 days of treatment. Cerebral blood flow changes, characteristics and treatment effect were analyzed and determined by clinical main symptom disappearance rate. Results: In concussion, cerebral blood flow was divided into 3 phases: cerebral blood flow low infusion dilation phase, cerebral blood vessel spasm phase and cerebral blood flow recovery phase. In the Nimodipine group, clinical main symptom disappearance rate was higher than that in the control group in the cerebral spasm and recovery phases with a significant difference (P<0.01).  Conclusions: Cerebral vessel spasm, hypoxia and ischemia lesion are the main pathological changes. Whether cerebral dysfunction is reversible or not is mainly determined by spasm time of cerebral blood vessel. Nimodipine has a good effect on releasing spasm and diminishing the cerebral blood flow velocity. It not only improves curative effect on concussion, but also reduces and prevents concussion sequelae. Hence, concussion patients who have cerebral spasm confirmed by 3D-TCD should be given Nimodipine routinely and early.

    In coronary artery bypass surgery, arterial grafts result in improved patency rates. However, these grafts frequently fail due to spasm. Papaverine has been used to prevent graft spasm, but its effect is short-lived. Botulinum toxin inhibits muscle contraction for about three months. We investigated the usefulness of botulinum toxin in preventing arterial grafts spasm in vitro. Samples of abdominal aorta from male Wistar rats were cut into 2 mm rings and treated with various doses of botulinum toxin or papaverine for 30 min. All rings were stimulated with KCl and noradrenaline. Tension was recorded using myography. We compared constriction caused by noradrenaline or KCl in rings treated with botulinum toxin, or papaverine, or physiological salt solution (PSS) (control). In the presence of KCl and noradrenaline, almost all concentrations of botulinum toxin completely inhibited arterial contraction when compared with controls. Spasm prevention was lost after 60 min in rings with papaverine but persisted for 120 min in rings with botulinum toxin. In the histological examination, arterial wall structure was not destroyed by botulinum toxin. Botulinum toxin prevented arterial graft spasm in vitro and had a longer lasting effect than papaverine, with no toxic effect on the artery.

    This prospective, open label, uncontrolled study was performed to evaluate the efficacy and tolerability of the modified Atkins diet in children with refractory infantile spasms. Fifteen consecutive children aged six months to three years having daily infantile spasms in clusters with electroencephalographic evidence of hypsarrhythmia despite treatment with hormonal treatment (oral corticosteroids/adrenocorticotrophic hormone) and/or vigabatrin, and at least one additional anti-epileptic drug were enrolled. Children with known or suspected inborn errors of metabolism or systemic illnesses were excluded. Carbohydrate intake was restricted to ten grams/day. Among these 12 boys and three girls (median age-24 months), 13 had symptomatic etiology. After three months of diet, six children were spasm free. The time to spasm freedom after diet initiation ranged from two days to two months. The most frequent adverse effect observed was constipation. The modified Atkins diet was found to be effective and well tolerated in children with refractory infantile spasms (ClinicalTrials.gov identifier: NCT01006811).

    Full Text Available Background/Aim. The diagnosis of bronchial asthma, a chronic inflammatory disease of the respiratory tract, is made on the basis of anamnesis, pathologic auscultatory findings of the lungs, lung function disturbances, skin tests, as well as the basic indices of immunologic condition in bronchial trunk. The aim of the study was to find out correlation of objective indices of the disease and than relation with the symptoms in the patients with bronchial asthma. Methods. The study included 60 young male non smokers with long lasting symptoms of bronchial asthma including shortness of breath, wheezing, hard breathing, nonproductive or productive cough, weakness and night hard breathing. There were no symptoms of respiratory infection over the past two months and lung radiography and spirometry were normal. Based on the results of nonspecific bronchoprovocative test two groups of the patients were formed, group I (n = 30 with positive histamine test (average value of the inhaled histamine concentration with FEV1 drop by 20% in regard with the initial value (PC20 = 2.99 ± 0.51 mg/ml of histamine and group II (n = 30 with negative histamine test (PC20(a = 14.58 ± 6.34 mg/ml of histamine. Results. The obtained spirometry results revealed a statistically significant difference in values of FEV1 between groups: I group - FEV1 = 93.2%; II group - FEV1 = 101.8%; (p < 0.05, Wilcoxon test, although all the FEV1 values were normal. Regarding the presence of the most common symptoms there was not statistically significant difference between the groups (p > 0. 05, chisquare test. Pathologic auscultatory lung findings were found in 73.4% of the patients in the group I and 27.5% of the patients in the group II. There was statistically significant difference (p < 0.05, chi-squared test. A positive correlation between the degree of hypersensitivity and lung physical findings was confirmed (p < 0.05 Spearman's rho, but there was no correlation with FEV1 values

    The objective of this study is to explore the incidence of inherited metabolic disorders (IMD) in infants with infantile spasms (IS), with an attempt to improve the early diagnosis and etiological and symptomatic treatment. Urine and blood samples were collected from 60 IS patients and analyzed for the quantification of amino acids, organic acids, and fatty acids by gas chromatography-mass spectrometry and tandem mass spectrum. Routine urine tests, hepatic function tests, blood biochemistry, brain imaging, as well as examinations of the brain stem auditory/visual evoked potentials were also examined. In addition to antiepileptic therapy, etiological and symptomatic treatments were also conducted in infants with confirmed IMD and the follow-up lasted for 6 months in these pediatric patients. Metabolic disorders were found in 28 (46.67 %) of 60 IS infants, among them 13 (21.67 %) were confirmed to be with IMD. Twelve of these 13 IS patients with definite IMD diagnoses (92.31 %) experienced varying degrees of delayed development of intelligence and motor function, 8 patients (61.54 %) had abnormal cranial CT or MRI findings, 11 patients (84.61 %) had abnormal brain stem evoked potentials, 4 patients (30.77 %) had abnormal hepatic functions, 3 patients (23.07 %) had abnormal blood biochemistry, 2 patients (15.38 %) had positive (+ to ++) results for routine urine ketones, and 2 patients (15.38 %) had skin lesions. After treatment in children who were diagnosed IMD, the well controlled epileptic seizures and the satisfactory developments in mental and motor were found in 4 cases of methylmalonic acidemia, 2 cases of classical phenylketonuria, and one case of biotin deficiency disease, glutaric acidemia type I, and 4-hydroxybutyric aciduria in each. IMD is a key biological cause in IS. Early screening for IMD is warranted in IS infants to facilitate the improvement for the prognosis and an early etiological treatment.

    Hemifacial spasm (HFS) is defined as an involuntary, irregular clonic, or tonic movement of muscles innervated by the ipsilateral seventh cranial nerve. It is reported that the coexistence of non-motor- and motor-related symptoms can be seen in patients with HFS. Postural disturbances were investigated in some movement disorders; however, postural abnormalities due to HFS had not been reported before. In this study, we aimed to investigate the postural abnormalities in patients with HFS. In this cross-sectional, controlled study, Tinetti Balance and Gait Test (TBGT) scores and static posturography were performed on fifteen patients with HFS and fifteen healthy age- and sex-matched controls. The total TBGT score and TBGT-balance score were found to be significantly lower in the patient group than in the control group (p values were, respectively, 0.046 and 0.011). The ratio of the patients with high risk of falling was 40 %, and the difference was found to be significantly higher in the patient group (p value = 0.008). In Fourier analyses, a significant difference was found in the medium to high frequencies (F5-6) when the posturographic evaluation was performed on a solid ground with closed eyes, head rotated to right, and head rotated to the left positions (p values were, respectively, 0.045 and 0.007). The stability index of the HFS group was significantly higher than the control group when tested on the neutral, head right, and head left positions (p values were, respectively, 0.004, 0.049, and 0.003). In conclusion, our study showed that the patients with HFS have more balance and falling problems than the controls, which can be both clinically and posturographically determined.

    Radioaerosol inhalation imaging (RII) has been used in radionuclide pulmonary studies for the past 20 years. The method is well accepted for assessing regional ventilation because of its usefulness, easy fabrication and simple application system. To evaluate its clinical utility in the study of impaired regional ventilation in bronchial asthma, we obtained and analysed RIIs in 31 patients (16 women and 15 men; age ranging 21-76 years) with typical bronchial asthma at the Department of Radiology, Kangnam St. Mary's Hospital, Catholic University Medical college, from January, 1988 to August, 1989. Scintiscans were obtained with radioaerosol produced by a HARC(Bhabha Atomic Research Center, India) nebulizer with 15 mCi of {sup 99m}Tc-phytate. The scanning was performed in anterior, posterior and lateral projections following 5-minute inhalation of radioaerosol on sitting position. The scans were analysed and correlated with the results of pulmonary function study and the findings of chest radiography. Fifteen patients had concomitant lung perfusion image with {sup 99m}Tc-MAA. Follow-up scans were obtained in 5 patients after bronchodilator therapy. 1 he patients were divided into (1) attack type (4 patients), (2) resistant type (5 patients), (3) remittent type (10 patients) and (4) bronchitic type (12 patients). Chest radiography showed hyperinflation, altered pulmonary vascularity, thickening of the bronchial wall and accentuation of hasal interstitial markings in 26 of the 31 patients. Chest radiographs were normal in the remaining 5 patients. Regardless of type, the findings of RII were basically the same, and characterized by the deposition of radioaerosol in the central parts or in the main respiratory air ways along with mottled nonsegmental ventilation defects in the periphery. Peripheral parenchymal defects were more extensive than that of expected findings from clinical symptoms, pulmonary function test and chest radiograph. Broomstick sign was present

    We report a very rare case of a 47-year-old man who had coronary spasm that resulted in a silent myocardial infarction, a ruptured myocardial wall, and a nonruptured left ventricular pseudoaneurysm. The patient presented with a 6-month history of dyspnea on exertion, without evidence of fixed coronary artery stenosis. Coronary angiography showed severe coronary spasm of the left anterior descending and left circumflex arteries; the spasm was relieved promptly by nitroglycerin. Echocardiography and left ventricular angiography revealed the large left ventricular pseudoaneurysm posterolateral to the left ventricle. We performed surgical resection of the pseudoaneurysm and patch repair of the ruptured left ventricular wall, with excellent results. We present this case because of the highly unusual sequence of events. Early surgical intervention resulted in the patient's recovery.

    Full Text Available Cerebral palsy is a non-progressive motor disorder which occurs due to hypoxic insult to fetus during perinatal period. These children often present for elective surgical procedures to correct various deformities. Peri-operative care of a child with cerebral palsy is a real challenge to the anaesthetics because of associated comorbidities. Yet another problem in these patients is behavior abnormality and difficulty in communication. Therefore regional anaesthesia is usually combined with general anaesthesia and not used alone. The two most important anaesthetics concerns in these patients are hypothermia and post-operative muscle spasm. Epidural analgesia is the most effective method of post-operative pain relief. Even though opioids can be used for post-operative analgesia, clonidine is more effective in relieving post-operative muscle spasm. In this case report we have discussed about the anesthetic management and postoperative muscle spasm in a child with cerebral palsy.

    Bilateral hemifacial spasm and Meige syndrome can be easily confused due to their similar clinical manifestation. Here, we aimed to investigate the application of electrophysiological methods and magnetic resonance tomographic angiography (MRTA) in the differentiation between hemifacial spasm and Meige syndrome. 10 patients with bilateral hemifacial spasm and 9 patients with Meige syndrome received electrophysiological monitoring of nerves. There were two males and eight females with bilateral hemifacial spasm, aged 16-58 years with a course of 5-54 months. For the patients with Meige syndrome, there were three males and six females, aged 51-68 years with a course of 12-36 months. All patients received conventional MRTA of the brain blood vessels before decompression. We found that all patients with Meige syndrome showed synchronous contraction of bilateral orbicularis oculi muscles and (or) burst discharge from orbicularis oris muscles in surface electromyography (sEMG). However, those with hemifacial spasm presented with bilaterally asynchronous burst discharge. Electromyography for patients with Meige syndrome did not record abnormal muscle response (AMR), but recorded AMR for those with bilateral hemifacial spasm. The offending vessels were compressed in patients with hemifacial spasm in MRTA, while MRTA results were generally negative for those with Meige syndrome. Combining sEMG and AMR detection in EMG and MRTA, bilateral hemifacial spasm can be differentiated from Meige syndrome with a reduction of misdiagnosis rate.

    Full Text Available Abstract Involuntary contractions of paralyzed muscles (spasms commonly disrupt daily activities and rehabilitation after human spinal cord injury. Our aim was to examine the recruitment, firing rate modulation, and derecruitment of motor units that underlie spasms of thenar muscles after cervical spinal cord injury. Intramuscular electromyographic activity (EMG, surface EMG, and force were recorded during thenar muscle spasms that occurred spontaneously or that were triggered by movement of a shoulder or leg. Most spasms were submaximal (mean: 39%, SD: 33 of the force evoked by median nerve stimulation at 50 Hz with strong relationships between EMG and force (R2>0.69. Unit recruitment occurred over a wide force range (0.2-103% of 50 Hz force. Significant unit rate modulation occurred during spasms (frequency at 25% maximal force: 8.8 Hz, 3.3 SD; at maximal force: 16.1 Hz, 4.1 SD. Mean recruitment frequency (7.1 Hz, 3.2 SD was significantly higher than derecruitment frequency (5.4 Hz, 2.4 SD. Coactive unit pairs that fired for more than 4 s showed high (R2>0.7, n=4 or low (R2:0.3-0.7, n=12 rate-rate correlations, and derecruitment reversals (21 pairs, 29%. Later recruited units had higher or lower maximal firing rates than lower threshold units. These discrepant data show that coactive motoneurons are driven by both common inputs and by synaptic inputs from different sources during muscle spasms. Further, thenar motoneurons can still fire at high rates in response to various peripheral inputs after spinal cord injury, supporting the idea that low maximal voluntary firing rates and forces in thenar muscles result from reduced descending drive.

    OBJECTIVE Hemifacial spasm (HFS) is a cranial nerve hyperactivity disorder characterized by unique neurophysiological features, although the underlying pathophysiology remains disputed. In this study, the authors compared the effects of desflurane on facial motor evoked potentials (MEPs) from the spasm and nonspasm sides of patients who were undergoing microvascular decompression (MVD) surgery to test the hypothesis that HFS is associated with a central elevation of facial motor neuron excitability. METHODS Facial MEPs were elicited in 31 patients who were undergoing MVD for HFS and were administered total intravenous anesthesia (TIVA) with or without additional desflurane, an inhaled anesthetic known to centrally suppress MEPs. All measurements were completed before dural opening while a consistent mean arterial blood pressure was maintained and electroencephalography was performed. The activation threshold voltage and mean amplitudes of the MEPs from both sides of the face were compared. RESULTS There was a significantly lower mean activation threshold of facial MEPs on the spasm side than on the nonspasm side (mean ± SD 162.9 ± 10.1 vs 198.3 ± 10.1 V, respectively; p = 0.01). In addition, MEPs were also elicited more readily when single-pulse transcranial electrical stimulation was used on the spasm side (74% vs 31%, respectively; p = 0.03). Although desflurane (1 minimum alveolar concentration) suppressed facial MEPs on both sides, the suppressive effects of desflurane were less on the spasm side than on the nonspasm side (59% vs 79%, respectively; p = 0.03), and M waves recorded from the mentalis muscle remained unchanged, which indicates that desflurane did not affect the peripheral facial nerve or neuromuscular junction. CONCLUSIONS Centrally acting inhaled anesthetic agents can suppress facial MEPs and therefore might interfere with intraoperative monitoring.

    Full Text Available Urachal carcinoma is rare comprising less than 1% of all bladder carcinomas. Metastases of urachal carcinoma have been reported to meninges, brain, ovary, lung, and maxilla. Cytologic features of metastatic urachal carcinoma have not been previously reported. We present a case of metastatic urachal adenocarcinoma in bronchial brushings and review the use of immunohistochemistry in its diagnosis. A 47-year-old female was seen initially in 2007 with adenocarcinoma of the bladder dome for which she underwent partial cystectomy. She presented in 2011 with a left lung mass and mediastinal adenopathy. Bronchoscopy showed an endobronchial lesion from which brushings were obtained. These showed numerous groups of columnar cells with medium sized nuclei and abundant cytoplasm. The cells were positive for CK20 and CDX2 and negative for CK7. The cytomorphological findings were similar to those in the previous resection specimen and concurrent biopsy. This is the first case report of bronchial brushings containing metastatic urachal carcinoma. No specific immunohistochemical profile is available for its diagnosis. The consideration of a second primary was a distinct possibility in this case due to the lapse of time from primary resection, absence of local disease, and lack of regional metastases.

    Low back pain (LBP), a high prevalent condition among middle aged population, is usually associated with 'muscle spasm' that is responsible for giving rise to pain as well as its persistence. Muscle spasm is an involuntary, painful contraction of muscles that interferes with the function and cause of muscular disorder. Therefore centrally acting skeletal muscle relaxants, also called lissive drugs, are commonly used for its treatment. Sometimes these are combined with NSAIDs. The use of centrally acting skeletal muscle relaxants, though efficacious, is associated with frequent development of dose-related adverse drug reactions like sedation, impairment of voluntary motor functions and ataxia. So there is an urgent need for newer better drugs for treatment of conditions associated with muscle spasm. The objective of this study was to assess the efficacy and safety of oral thiocolchicoside (TC), a natural glycoside as compared to an adrenergic alpha 2 agonist tizanidine (TZ) in the Indian patients with LBP accompanied by muscle spasm. In this randomised, non-cross over clinical study, 60 adult Indians aged between 18 and 65 years with clinical diagnosis of muscle spasm associated with low back pain were enrolled. Patients satisfying the inclusion and exclusion criteria were either treated with TC and TZ for one week duration. Visual analogue scale (VAS) for pain at rest and VAS for tiredness, drowsiness, dizziness and alertness was used as the self-rated primary efficacy and safety variable. Pain was also assessed by mobility assessment; muscle spasm assessment and analgesic consumption. Data obtained from 58 patients (those who completed the study) indicated that in this one week study both TC and TZ provided sustained symptoms relief compared with the baseline. There was statistically significant reduction in severity of symptoms from day 0 to day 7 in both the groups. Patients were followed up on 3rd and 7th day and severity score of various parameters was

    Papillary muscle rupture usually occurs as a catastrophic complication of acute myocardial infarction in patients with coronary artery stenosis; it is therefore less common in patients without coronary artery stenosis. We report the case of a 67-year old woman without coronary artery stenosis who suffered an acute anterolateral papillary muscle rupture and was successfully treated with mitral valve replacement. Evidence of coronary spasm was found on a coronary vasomotion test, suggesting that a high sensitivity to coronary spasm may explain a mechanism of isolated papillary muscle infarction.

    Neuromyelitis optica (NMO) is an inflammatory-demyelinating disease of the central nervous system classically characterized by optic neuritis and severe myelitis. New diagnostic criteria defined neuromyelitis optica spectrum disorder as limited forms of NMO or diverse neurologic presentations in the presence of specific antiaquaporin-4 antibodies. We report the case of a 57-year-old woman admitted in our department for recurrent attacks of optic neuritis, tetraparesis with severe painful tonic spasms of the left limbs and brainstem involvement. Painful tonic spasms have been described as movement disorders associated with multiple sclerosis, but a growing number of reports describe them in cases of NMO.

    Background Hemifacial spasm (HFS) is a facial nerve disorder characterized by episodic involuntary ipsilateral facial muscle contraction.Information on Chinese patients with HFS has not been well-characterized.This study aimed to evaluate the clinical feature and the treatment status of HFS across China.Methods A cross-sectional study including 1003 primary HFS patients had been carried out in 15 movement disorder clinics in China in 2012.The investigated information was acquired from questionnaires and medical records including demographic data,site of onset,aggravating and relieving factors,treatments prior to the investigation,etc.Results In this study,the ratio of male to female was 1.0:1.8,the mean age at onset was (46.6±11.5) years.About 1.0% patients were bilaterally affected.The most often site of initial onset was the orbicularis oculi muscle.The most often affected sites were orbicularis oculi,zygomatic,and orbicularis oris muscles.Stress/anxiety and relaxation were most often aggravating and relieving factors,respectively; 2.3% patients had family history,28.4% cases were combined with hypertension,and 1.4% patients were with trigeminal neuralgia.Botulinum toxin type A (BTX-A) injection was the most commonly used treatment,followed by acupuncture and oral medication.BTX-A maintained the highest repeat treatment ratio (68.7%),while 98.4% patients gave up acupuncture.The mean latency of BTX-A effect was (5.0±4.7) days,the mean total duration of the effect was (19.5±11.7) weeks,and 95.9% patients developed improvements no worse than moderate in both severity and function.The most common side effect was droopy mouth.Conclusions The onset age of HFS in China is earlier than that in western countries.The most often used two treatments are BTX-A injection and acupuncture,while the latter kept the poor repeat treatment ratio because of dissatisfactory therapeutic effect.

    Full Text Available Bronchial webs are thin, membrane-like diaphragms that may obstruct the airway. Several congenital cases have been reported. Though rare, the true incidence of these lesions is probably underestimated because many of them are unrecognized. The case of a 71-year-old woman with an acquired bronchial web causing right main stem bronchus obstruction that went unrecognized for 47 years post-trauma is reported. The lesion was successfully treated using rigid bronchoscopy with laser therapy, balloon dilation and stent placement. This is the first reported case of an acquired bronchial web formation. It is also the first reported case that was successfully treated with this technique.

    Full Text Available Neuromyelitis optica or Devic’s syndrome is a rare autoimmune disorder which is characterized by inflammatory demyelination of the optic nerves and the spinal cord. Clinically, it causes visual loss in one or both eyes, and numbness or paralysis of the arms and legs. Although tonic spasm is the most frequent movement disorder occuring in MS, it has not been definetely described clinical entity for Devic’s syndrome. We hereby describe a case of Devic’s syndrome with tonic spasms treated with levetiracetam as a new approach and discussed the results of the treatment. A 52-year-old woman with Devic’s syndrome with the complaint of painful tonic spasms primarily affecting the abdomen was given levetiracetam therapy. Levetiracetam therapy resulted in a good response in our patient. Levetiracetam can be a new choice for the treatment of painful tonic spasm with Devic’s syndrome. However, more detailed studies are necessary to investigate efficacy of levetiracetam.

    This is the report of two cases of infantile spasms, manifesting transient brain shrinkage in computerized tomography (CT) after ACTH treatment. ACTH was given for 8 weeks to a 8-months-old Japanese girl with infantile spasms. First CT performed at 2 weeks after the final ACTH injection, displayed moderate brain shrinkage. Second CT at 4 months showed marked diminution of the shrinkage. ACTH was also given for 8 weeks to a 14 months old Japanese boy with infantile spasms. First CT, just before ACTH treatment, showed mild cortical atrophy, the second at 7 days after the final ACTH injection revealed marked brain shrinkage and moderate ventricular dilatation, and the third at 2 months, disclosed mild improvement of the shrinkage. ACTH or corticoateroid has widespread effects on the developing nervous system. In animal experiments, ACTH or steroids interfere with brain growth of young rats. CT findings of transient brain shrinkage in a child with infantile spasms might suggest that intensive treatment with ACTH or steroids in infancy interferes with brain growth as seen in the results of animal experiments.

    Objective To study the immunoreactivity of Calcitonin gene-related peptide (CGRP) in the facial nerve when Hemifacial Spasm is occurring. Methods The electrophysiological technique was used to explore abnormal muscle response (AMR) which was characteristic of Hemifacial Spasm.The animal models of Hemifacial Spasm in New Zealand white rabbits were established by compressing the main trunk of artificial demyelinated facial nerve with the temporal superficial artery. At 6 weeks after surgery, the facial nerves were taken from the experimental group and control one, the immunohistochemistry for CGRP using polyclonal antibody with ABC kit was performed in the facial nerves; at the same time, the observation for the facial nerves of light and transmission electron microscope was performed. Results The facial nerve demyelinated and the axons retrogressively changed, CGRP immunoreactive positive fibers were significantly detected in experimental groups; whereas this phenomenon was not found in control group. Conclusion CGRP can nutrien the injured facial nerve and plays an important role in the pathogenesis of Hemifacial Spasm.

    2009-01-01

    Functional (non-organic) disorders of the iliopsoas muscle (IPM), i.e. the shortening, spasm and weakness of the structurally unchanged IPM, can be manifested as abdominal and/or pelvic pain, pain in areas of the thoracolumbar (ThL) and lumbosacral (LS) spine, sacroiliac (SI) joint, hip, groin and anterior thigh on the side of the affected muscle as well as gait disturbances (iliopsoas muscle syndrome). By clinical examination of the IPM, including the transabdominal palpation, stretch and strength tests, pathological masses, shortening, painful spasm, weakness and tendon tenderness of that muscle can be diagnosed. The IPM is, like other postural muscles, inclined to shortening. The weakness of the IPM can be a consequence of the lesion of the lumbar plexus or femoral nerve that innervate the IPM, as well as a consequence of certain organic diseases of the IPM. Painful stimuli coming from somatic and visceral structures that are innervated from Th12-L4 nerve roots, from which the IPM segmental innervation also originates, can cause a reflex spasm of the IPM. A painful spasm of the IPM caused by disorders of the ThL and LS spine, SI and hip joint, can mimic diseases of the abdominal and pelvic organs. In the differential diagnosis of the IPM painful spasm, organic diseases of that muscle should be considered foremost (abscess, hematoma, tumor, metastase), as they can result in spasm, and the diseases of the abdominal and pelvic organs that can cause an IPM reflex spasm. The IPM functional disorders, which are not rare, are often overlooked during a clinical examination of a patient. Reasons for overlooking these disorders are: 1) a nonspecific and variable clinical picture presenting the IPM functional disorders, 2) the IPM functional disorders are a neglected source of pain, 3) the inaccessibility of the IPM for inspection, 4) the lack of knowledge of the IPM examination techniques and 5) the IPM functional disorders cannot be discovered by radiological

    Familial cases of West syndrome have been reported only in Japan. In that study no chromosomal analyses were made. It has been suggested that microarray analysis should be included in the diagnostic evaluation of patients with infantile spasms and developmental delay, when an evaluation for structural brain lesions and metabolic disorders reveal no abnormal findings. We report here the first case of infantile spasms and 15q11.2q13.1 chromosome duplication in two successive generations. The daughter and mother with infantile spasms, and the autistic son had the duplication. The clinical course of infantile spasms was very similar in the mother and daughter. The spasms were primarily considered to be of unknown aetiology. Chromosomal microarray analysis revealed a 6.2 Mb size 15q11.2q13.1 duplication. The duplication belongs to the 15q11q13 duplication syndrome (OMIM 608636) which when maternally derived is characterised by neuro-behavioural disorders like autism, hypotonia, cognitive deficit, language delay and epilepsy. The proportion of patients with unknown aetiology for infantile spasms will decrease when more careful chromosomal studies are made. Our report expands the phenotype of chromosome 15q duplication syndrome and is the first report of this abnormality in two successive generations of infantile spasms.

    Adult mongrel dogs were used. The posterior communicating artery was punctured with a fine needle and subarachnoid hemorrhage was produced, which simulated aneurysmal rupture in human. The cerebral basal arteries were constricted remarkably after the puncture. However this vasospasm disappeared in about 60-120 minutes. After this restoration, the vessels began to be constricted again and reduced their diameter in greater degree with lapse of time. Effect of various drugs and sympathectomy on the experimental spasm induced by this method were studied utilizing the magnified vertebral angiography. The drugs used were papverine, isoxuprine, methysergide, phentolamine and propranolol. One of these drugs was given to each dog into the vertebral artery 15 minutes after the puncture of the artery for study of the early spasm, and the same procedure was carried out 24 hours after the late spasm. Vertebral arteriograms were taken immediately after and at 5, 10 and 30 minutes after injection of the drug. Diameter changes of the cerebral basal arteries were measured on the film. Smooth muscle relaxtants, papaverine and isoxsuprine, were effective on relieving the early and the late spasm. An antiserotonin agent, methysergide, relieved slightly the early spasm, but it had no effect on the late spasm. Phentolamine, that is an adrenergic blocking agent, relieved the early spam remarkably, but it was less effective on the late spam. A beta adrenergic blocking agent, propranolol, was effective on relieving neither the early nor the late spasm. Two weeks after the removal of the bilateral upper cervical ganglia, subarachnoid hemorrhage was produced by the smae method as mentioned above in four dogs. Arteriograms taken 24 hours after puncture of the posterior communicating artery in these dogs showed vasoconstriction as same as in the non-sympathectomized dogs. From these experimental results, it was suggested that an etiological difference in the early and the late spasm may exist

Objective Infantile spasms (IS are among the most catastrophic epileptic syndromes of infancy. The purpose of this study was to compare efficacy and safety of topiramate (TPM and nitrazepam (NZP as first-line drugs in the treatment of IS. Materials & Methods In a parallel single-blinded randomized clinical trial, 50 patients with IS referred to Pediatric Neurology Clinic of Shahid Sadoughi University of Medical Sciences, Yazd, Iran, were evaluated from September 2008 to March 2010. Patients were randomly assigned to two groups to be treated with TPM or with NZP for 6 months. The primary endpoint was efficacy in cessation of all spasms or reduction of more than 50% in weekly seizure frequency, which was evaluated before and 6 months after the drug use. Secondary outcome was clinical sideeffects of the drugs. Results Twenty boys (40% and 30 girls (60% with the mean age of 9.4±3.8 months were evaluated. Cessation of all spasms occurred in 12 (48% infants in TPM group and 4(16% in NZP group. Eight (32% children in TPM group and 7 (28% in NZP group had more than 50% reduction in spasms frequency. So, TPM was more effective. Side effects were seen in 32% of TPM and in 36% of NZP groups. Conclusion Topiramate is an effective and safe drug, which might be considered as the firstline drug for the treatment of ISs.

    Radial artery spasm is a frequent complication of the transradial approach for coronary angiography and angioplasty. Recently, we have been able to quantify spasm using the automatic pullback device. The objective of this study was to assess the efficacy of an intra-arterial vasodilating cocktail in reducing the incidence and severity of radial artery spasm. A hundred patients undergoing coronary procedures via the radial artery were divided into two groups of 50 each. Patients in group A received intra-arterial cocktail (5 mg of verapamil plus 200 micro g nitroglycerine in 10 ml of normal saline), while patients in group B did not receive any vasodilating drug. The pullback device was used for sheath removal at the end of the procedure. Seven (14%) patients in group A experienced pain (i.e., pain score of III-V) during automatic sheath removal, as compared to 17 (34%) in group B (P = 0.019). The mean pain score was significantly lower in group A than in group B (1.7 +/- 0.94 vs. 2.08 +/- 1.07; P = 0.03). The maximal pullback force (MPF) was also significantly lower for group A (0.53 +/- 0.52 kg; range, 0.10-3.03 kg) as compared to group B (0.76 +/- 0.45 kg; range, 0.24-1.99 kg; P = 0.013). Only 4 (8%) patients in group A had an MPF value greater than 1.0 kg, suggesting the presence of significant radial artery spasm, as opposed to 11 (22%) in group B (P = 0.029). Administration of an intra-arterial vasodilating cocktail prior to sheath insertion reduces the occurrence and severity of radial artery spasm.

    Congenital lung malformations are increasingly detected before birth. However, bronchial atresia is rarely identified in utero and not always recognized in neonates. There are two types of atresia: (1) proximal, located at the level of the mainstem or the proximal lobar bronchi, which is extremely rare and usually lethal during pregnancy, causing a tremendous volume increase of the distal involved lung with secondary hypoplasia of the normal lung, and (2) peripheral, located at the segmental/subsegmental bronchial level, which may present as an isolated lesion or as part of a complex congenital malformation. Prenatal findings are mostly nonspecific. Postnatal exams show overinflated lung areas and focal bronchial dilations. The typical fluid-filled bronchoceles are not always observed in neonates but develop progressively in the first months of life. This pictorial essay describes the spectrum of imaging findings of bronchial atresia in fetuses, neonates and infants. (orig.)

    Full Text Available Background. The control of severe bronchial asthma, such as corticosteroid-resistant asthma, is difficult. It is also possible that immunosuppressive agents would be effective for bronchial asthma. Case Summary. A 55-year-old Japanese female presented with severe bronchial asthma controlled with tacrolimus. She had been diagnosed with bronchial asthma during childhood. Her asthma worsened, and a chest radiograph showed atelectasis of the left lung. Bronchoscopy revealed the left main bronchus to be obstructed with viscous sputum consisting of 82% neutrophils and no eosinophils. The atelectasis did not improve with corticosteroid treatment, but was ameliorated by administration of tacrolimus. Discussion. This patient had severe asthma due to neutrophilic inflammation of the airways. Tacrolimus is effective for treating severe asthma, for example, in corticosteroid-resistant cases.

    The authors discuss the efficacy of methacholine challenge to discriminate fit subjects to military service. We evaluated the relation between bronchial hyperreactivity and clinical symptoms, airways caliber and atopic status in a group of italian conscripts who reported to have bronchial asthma. Five-hundred-four subjects were studied. Bronchial hyperreactivity was measured by methacholine test, and atopic status was assessed by skin-tests. A measurable PC20 FEV1 was detected in 424 subjects. On the basis of the methacholine threshold concentration the overall sample was divided in four categories. The four categories differed as regards onset of disease, lung function and skin reactivity towards Dermatophagoides Pter, whereas no difference was found as regards skin reactivity towards Grass. In the group evaluated in spring, the four categories differed as regards skin reactivity towards Grass. In conclusion we found that bronchial hyperreactivity is related to clinical history, lung function and atopic status; the measurement of bronchial hyperreactivity is important to evaluate conscripts referring bronchial asthma.

General characteristics of the patients including age, gender, etiology, and thorax computed tomograms, findings of bronchial angiographic, results of the embolization, complications related to bronchial artery embolization and clinical outcome during follow-up were reviewed. Results: The etiology included previous pulmonary tuberculosis in 20 cases, previous tuberculosis with bronchiectasis in 16 cases, bronchiectasis in 6 cases, and active pulmonary tuberculosis in one case. No identifiable causes could be detected in three patients. Moreover, massive hemoptysis was successfully and immediately controlled following the embolization procedure in all patients. One patient developed recurrent hemoptysis during one month following the procedure and was treated by re-embolization. No major procedure–related complication such as bronchial infarction was identified However none of the patientsexperienced neurological complications. Conclusion: Bronchial artery embolization is a safe and effective means of controlling massive hemoptysis and should be regarded as the first-line treatment for this condition.

    The prevalence of allergic respiratory diseases such as bronchial asthma has increased in recent years, especially in industrialized countries. A change in the genetic predisposition is an unlikely cause of the increase in allergic diseases because genetic changes in a population require several generations. Consequently, this increase may be explained by changes in environmental factors, including indoor and outdoor air pollution. Over the past two decades, there has been increasing interest in studies of air pollution and its effects on human health. Although the role played by outdoor pollutants in allergic sensitization of the airways has yet to be clarified, a body of evidence suggests that urbanization, with its high levels of vehicle emissions, and a westernized lifestyle are linked to the rising frequency of respiratory allergic diseases observed in most industrialized countries, and there is considerable evidence that asthmatic persons are at increased risk of developing asthma exacerbations with exposure to ozone, nitrogen dioxide, sulphur dioxide and inhalable particulate matter. However, it is not easy to evaluate the impact of air pollution on the timing of asthma exacerbations and on the prevalence of asthma in general. As concentrations of airborne allergens and air pollutants are frequently increased contemporaneously, an enhanced IgE-mediated response to aeroallergens and enhanced airway inflammation could account for the increasing frequency of allergic respiratory allergy and bronchial asthma. Pollinosis is frequently used to study the interrelationship between air pollution and respiratory allergy. Climatic factors (temperature, wind speed, humidity, thunderstorms, etc) can affect both components (biological and chemical) of this interaction. By attaching to the surface of pollen grains and of plant-derived particles of paucimicronic size, pollutants could modify not only the morphology of these antigen-carrying agents but also their allergenic

    Women with urinary urgency and frequency may also have pelvic floor muscle spasm. Transvaginal biofeedback (TVBF) and electrical stimulation (EStim) is a treatment modality that has been used to treat vaginismus and chronic pelvic pain. In this study, TVBF/EStim was evaluated in women with pelvic floor muscle spasm associated with urinary symptoms. Fifty-two women underwent therapy with TVBF/EStim and reported a mean symptom improvement of 64.5%.

    Full Text Available Infection with respiratory viruses, including rhinoviruses, influenza virus, and respiratory syncytial virus, exacerbates asthma, which is associated with processes such as airway inflammation, airway hyperresponsiveness, and mucus hypersecretion. In patients with viral infections and with infection-induced asthma exacerbation, inflammatory mediators and substances, including interleukins (ILs, leukotrienes and histamine, have been identified in the airway secretions, serum, plasma, and urine. Viral infections induce an accumulation of inflammatory cells in the airway mucosa and submucosa, including neutrophils, lymphocytes and eosinophils. Viral infections also enhance the production of inflammatory mediators and substances in airway epithelial cells, mast cells, and other inflammatory cells, such as IL-1, IL-6, IL-8, GM-CSF, RANTES, histamine, and intercellular adhesion molecule-1. Viral infections affect the barrier function of the airway epithelial cells and vascular endothelial cells. Recent reports have demonstrated augmented viral production mediated by an impaired interferon response in the airway epithelial cells of asthma patients. Several drugs used for the treatment of bronchial asthma reduce viral and pro-inflammatory cytokine release from airway epithelial cells infected with viruses. Here, I review the literature on the pathogenesis of the viral infection-induced exacerbation of asthma and on the modulation of viral infection-induced airway inflammation.

    1. Needle acupuncture was performed at three sites in twenty patients in a clinical attack of bronchial asthma. 2. In all patients the symptoms of bronchoconstriction improved during the attacks when the correct site was stimulated, and in five patients wheezing was abolished. 3. Stimulation at the correct site produced a significant increase in the mean FEV1-0 (58%) and FVC (29%) but not in maximal mid-expiratory flow rate (MMFR; 76%), when compared with the findings before acupuncture, along with a significant fall in the Pa,CO2 and an insignificant fall in Pa,O2. A mild tachycardia was also observed. 4. After acupuncture a greater improvement in FEV1-0, FVC and MMFR was produced by inhalation of isoprenaline. 5. No significant changes in FEV1-0, FVC, MMFR, pulse rate or arterial blood gas tensions occurred after acupuncture at control sites. 6. In four of the patients during clinical remission acupuncture was performed before and after histamine aerosol challenge, but there was no effect on either the severity or the duration of the histamine-induced bronchoconstriction. 7. It is concluded that acupunture probably reduced the reflex component of the bronchoconstriction, but failed to influence direct smooth muscle constriction caused by histamine.

    Full Text Available Hemimasticatory spasm (HMS is a rare disorder of the trigeminal nerve characterized by paroxysmal involuntary contractions of the unilateral jaw-closing muscles. HMS has been frequently described in association with facial hemiatrophy or localized scleroderma. A 42-year-old female presented with involuntary paroxysmal spasms of the left face, of 6 months duration. Her lower face on the left was markedly hypertrophied without skin lesions. An electrophysiological study indicated that the masseter reflexes and masseteric silent period were attenuated on the affected side. Surface electromyography demonstrated irregular bursts of motor unit potentials at high frequencies up to 200 Hz. Magnetic resonance imaging of the head showed marked hypertrophy of the left masseter muscle. Biopsy of the hypertrophied masseter muscle was normal. Repeated local injections of botulinum toxin noticeably reduced the size of the hypertrophied muscle as well as improved the patient’s symptoms.

    Hemimasticatory spasm is a rare disease; with little knowledge of the pathogenesis, it has still been intractable today. We presented a 56-year-old woman with involuntary painful spasm in her left masseter muscle for 11 years. The patient was successfully treated with microvascular decompression surgery. An offending superior cerebellar artery was found to contact with the motor branch of the trigeminal nerve root, which was then removed away and pieces of soft wadding were interposed between the nerve and the vessel to assure the separation. Postoperatively, the symptom totally disappeared and no recurrence was observed during the 7 months' follow-up. The treatment as well as the pathogenesis of the disease was reviewed, and we put forward a new hypothesis.

    In the present paper, the authors sum up results of acupuncture treatment of 35 cases of facial spasm. Of the 35 cases, 14 were male and 21 female, ranging in age from 19 to 62 years and in the disease duration from 1 week to 21 years. Shallow needling was applied to the surrounding region of Ahshi points (the twitching locus), Hegu (LI 4), Taichong (LR 3), etc., once daily, 4 weeks altogether. In addition, according to syndrome differentiation, other acupoints as Fengchi (GB 20), Waiguan (TE 5), Zusanli (ST 36), Sanyinjiao (SP 6), etc. were supplemented. After treatment, out of the 35 cases, 26 (74.3%) were cured, 5 (14.3%) experienced markedly improvement, and the rest 4 (11.4%) cases had a certain degree of amelioration. The key point for treating facial spasm is applying shallow needling around the twitching muscles.

    Fifty-one patients with hemifacial spasm secondary to facial nerve compression by normal appearing, elongated, tortuous and/or dilated arteries, were treated by microsurgical neurovascular decompression. Post-operatively, 91% of 44 of these patients with one to six year postoperative follow-ups were satisfactory. The angiographic findings showed significant increase in the number of common trunk anomalies. Variations of the anterior and posterior inferior cerebellar and vertebral arteries are discussed in relation to nerve compression.

    Blepharospasm is a focal dystonia characterized by involuntary, repetitive eye closure. Orofacial and oromandibular dystonia describe involuntary dystonic movements of orofacial and oromandibular musculature. Hemifacial spasm is characterized by repetitive synchronous contraction of facial nerve innervated muscles on one side of the face. In this article, the clinical presentation, epidemiology, and approaches to treatment are reviewed. Technical aspects of using botulinum toxin for treatment and reported outcomes are discussed.

  14. Connective Tissue Growth Factor Expression in Human Bronchial Epithelial Cells

    2006-01-01

    Connective tissue growth factor (CTGF) is a cysteine-rich protein that promotes extracellular matrix deposition. CTGF is selectively induced by transforming growth factor β and des-Arg kallidin in lung fibroblasts and increases steady-state mRNA levels of α type I collagen, 5α-integrin and fibronectin in fibroblasts. Bronchial epithelial cells have been proposed to functionally interact with lung fibroblasts. We therefore investigated if bronchial epithelial cells are able to synthesize CTGF. Human bronchial epithelial cells were grown to subconfluence in standard growth media. Proliferating cells grown in small airway growth media were harvested following starvation for up to 24 h. Expression of CTGF transcripts was measured by PCR. Immunocytochemistry was also completed using a commercially available antibody.The cells expressed readily detectable CTGF transcripts. Starvation of these cells resulted in a quantitative decline of CTGF transcripts. Direct sequencing of the PCR product identified human CTGF. Immunocytochemistry confirmed intracellular CTGF in the cells and none in negative control cells. We conclude that bronchial epithelial cells could be a novel source of CTGF. Bronchial epithelial cell-derived CTGF could thus directly influence the deposition of collagen in certain fibrotic lung diseases.

    1978-04-01

    Full Text Available Delayed cerebral vasospams is caused by excessive accumulation of dopamine-beta-hydroxylase (DBH and noradrenaline in cerebral vessel walls. This study demonstrates the mechanisms of delayed spasm, particularly the role of red blood cell components, and the successful relief of delayed cerebral vasospasm. Spasmogenic substances which contained a heme component, such as methemoglobin, methemalbumin and catalase enhanced DBH activity in human serum as measured by a one step chemical spectrophotometric assay. The concentration which gave the highest DBH activity caused the maximum constriction of the basilar artery, when the substances were applied topically. Among components of red cells, methemoglobin, methemalbumin, catalase and nicotinamid adenin dinucleotide (NADH caused constriction of basilar artery in cats, when applied topically, whereas hematin, hemin and bilirubin caused no significant spasm. An oxyhemoglobin solution obtained by mixture with methemoglobin and ascorbic acid produced no significant vascular spasm either. Relief of delayed cerebral vasospasm was obtained with topical application of specific alpha adrenergic blocking drug such as phenoxybenzamine, specific inhibitors of DBH such as fusaric acid, o-phenanthroline and alphaalpha' dipyridyl beta2 adrenergic stimulants such as salbutamol, and a phosphodiesterase inhibitor, ascorbic acid.

    We present the case of a 65-year-old male with vasospastic angina(VSA)whose condition worsened during the perioperative period.He had been diagnosed with VSA 10 years prior.He was treated with two types of vasodilators and had not experienced any chest symptoms for 5 years.At this juncture,he underwent surgery for relapsed maxillary sublingual carcinoma.He had taken two vasodilators one day prior to surgery.Intravenous infusion of nitroglycerin(NTG)was initiated immediately before the surgery and continued the following day.Instead of stopping NTG,a dermal isosorbide dinitrate tape was applied on post-operative day 1.Two days later,a complete atrioventricular block with pulseless electrical activity appeared.After cardiopulmonary resuscitation,emergent coronary angiography showed severe coronary spasm in both the left and right coronary arteries.Intracoronary infusion of nitroglycerin and epinephrine with percutaneous cardiopulmonary support relieved the coronary spasm.During the perioperative period,several factors can trigger coronary vasospasm,including the discontinuation of vasodilators.Thus,surgeons,anesthetists,and cardiologists should watch for coronary vasospasm during this period and for worsening coronary spasm when discontinuing vasodilators in patients at risk for VSA.

    We herein report a case of recurrent pneumothorax associated with congenital bronchial atresia. A 26-year-old male presented with chest pain. Chest roentgenograms showed left pneumothorax, a left apical bulla and an area of hyperlucency in the left upper lung field, and chest computed tomography revealed a discontinuation of the left superior bronchus. Additionally, both ventilation and perfusion scintigraphy showed a defect in the left superior segment. A thoracoscopy-assisted left superior segmentectomy was performed, and a pathological examination indicated left superior segmental bronchial atresia, which might have predisposed the peripheral lung to emphysematous conditions. No relapse was observed 6 months after the operation. Although this entity is rare, congenital bronchial atresia should be considered in the differential diagnosis when a patient has suffered from a recurrent spontaneous pneumothorax.

    Full Text Available Abstract. Bronchial asthma is a classic psychosomatic disease by immunopathological origin. In present investigation, we studied influence of body-oriented psychotherapeutic methods directed towards clinico-immunological parameters and special psychological features of the patients with bronchial asthma, i.e., decrease in alexithymia, as an important pathogenetic factor of bronchial asthma, and improvement in motor coordination and interhemispheric interactions in motor sphere. We investigated 38 patients (18 men and 20 women, while discriminating those patients who underwent a course of body-oriented psychotherapy, and a group of comparison, who did not undergo similar therapy. When observing conventional standards of randomization according to sex, age, clinical variants, and disease severity, some heterogeneity of these groups was revealed. In general, the people with active life attitude, being ready to work with a psychologist, possessed special features both in psychological and immunological spheres.

    BACKGROUND: Microvascular decompression has become a well-accepted, safe method in the treatment of hemifacial spasms. However, postoperative complications exist and influence the prognosis of the disease.OBJECTIVE: This study aimed to analyze, by case review, the characteristics and regularity of microvascular decompression complications in the treatment of hemifacial spasm. DESIGN: Retrospective analysis.SETTING: Beijing General Group Hospital of the Chinese People's Armed Police Forces.PARTICIPANTS: A total of 156 patients with hemifacial spasm were admitted to the Department of Neurosurgery, Beijing General Group Hospital of the Chinese People's Armed Police Forces from June 2004 to June 2006 and recruited for this study. The patients, 57 males and 99 females, averaged 46 years of age (range 17-68-years old). All suffered from facial innervated muscular paroxysmal and recurrent contraction, which could not be controlled by consciousness. Electromyogram demonstrated waves of fibrillation and fasciculation. Prior to admission, all patients had received other treatments. Written informed consents for treatment were obtained from all patients. This protocol was approved by the Hospital’s Ethics Committee. METHODS: After anesthesia, a cranial bone pore was drilled below the connection of the lateral sinus and sigmoid sinus. Dura mater was dissected at the "⊥" shape and held in the air. Under microscopy, the flocculus cerebelli was lifted slightly up for convenient observation of the cerebellopontine angle. The mucous membrane was sharply separated. Corresponding vessels were identified at the root of the facial nerves and subsequently liberated and disassociated from the root exit zone. Suitably sized Teflon cotton was placed between the corresponding vessels and brain stem.MAIN OUTCOME MEASURES: Complications of microvascular decompression.RESULTS: All 156 patients participated in the final analysis. ① Postoperatively, 66 (42%) patients presented with obvious

    Purpose: We aimed to retrospectively evaluate bronchial and nonbronchial systemic arteries using multi-detector row helical computed tomographic (MDCT) angiography in patients with pulmonary disorders. Materials and Methods: Thirty-nine patients (24 men, 15 women; mean age, 63.4 years; range, 20-82 years) with congenital and acquired pulmonary disorders of the bronchial and nonbronchial systemic arteries underwent multi-detector row helical computed tomographic angiography of the thorax using a 16-detector row scanner. Each of these patients had experienced an episode of hemoptysis. Computed tomographic angiogram data, which included maximum intensity projections, multiplanar reconstruction, and three-dimensional volume-rendered images, were used to retrospectively analyse the characteristics of the bronchial and nonbronchial systemic arteries. Results: We identified a total of 128 bronchial arteries (76 on the right side and 52 on the left) in 39 patients. We detected 42 nonbronchial systemic artery branches, including 19 internal mammary artery branches, 8 subclavian artery branches, 8 inferior phrenic artery branches, 5 intercostal artery branches, 1 thyrocervical trunk branch, and 1 celiac trunk branch. Thirty-five dilated and tortuous nonbronchial systemic arteries entered into the lung parenchyma and extended down to the lesions. Every case, except the one case of sequestration, was associated with pleural thickening where the vascular structures passed through the extrapleural fat. Conclusions: The variations in both the bronchial artery anatomy and the location and type of the nonbronchial arteries were great. Nonbronchial arteries may be a significant source of hemoptysis. MDCT angiography can be used to detect detailed anatomical information about the origins and courses of bronchial and nonbronchial systemic arteries and their pathophysiologic features.

    Diglycidyl ether of bisphenol A (DGEBA) epoxy resins belong to the most common causes of occupational allergic contact dermatitis. DGEBA has on rare occasions caused occupational asthma. Here we present a patient who first developed occupational allergic contact dermatitis (ACD) caused by a single accidental exposure to DGEBA. Then, on continued occupational exposure to DGEBA, the patient developed occupational asthma from DGEBA, in addition to ACD. A bronchial provocation test with DGEBA caused a 36% drop in the peak expiratory flow, reflecting a delayed type of occupational asthma. This bronchial provocation test caused a strong dermatitis of the exposed skin of the face, in accordance with airborne ACD from DGEBA.

    In the article, a new method of diagnosing the extent of the tumor spread in the bronchial wall without involvement of the mucosa (a peripbronchial form of the growth) is described. The method consists of two components - angiography of bronchial arteries with subsequent injection of a staining material in the corresponding bronchial artery and bronchoscopy, by means of which staining of the mucous membrane of the bronchial tree is observed. In case of tumor infiltration of the bronchial wall staining was absent completely or partially. A clinical trial of the method indicated its high efficacy.

    The actions on the bronchial smooth muscle and cardiovascular system S-1540 (Bitolterol) (Shionogi Pharmaceuticals), a new bronchodilator which is chemically related to isoprenaline, and S-1541 which is the active metabolite of S-1540 were studied in comparison with the action of isoprenaline (isoproterenol) and orciprenaline (metaproterenol). 1) The relaxing effect on isolated guinea-pig tracheal muscle constricted previously with histamine BaCl2 or acetylcholine was highest with S-1541, followed by isoprenaline and orciprenaline, in that order, and lowest with S-1540. The relaxing effect of S-1541 on acetylcholine-induced tracheal constriction was reduced and that of S-1540 was completely abolished by a previous treatment with propranolol. The relaxing actions of those drugs on bronchial spasms induced by histamine in vivo were highest with S-1541, followed by isoprenaline, and lowest with S-1540. 2) All these drugs exhibited the depressor and positive chronotropic actions in guinea-pigs. The potencies of the actions were found to be in the following order; isoprenaline was most potent, followed by S-1541 with a little less intensity, orciprenaline much weaker, and S-1540 still weaker with a positive chronotropic action of about 1/1000 of S-1541 and depressor action about 1/500. In the open chest guinea-pig, positive inotropic and chronotropic actions of S-1541 were about the same or slightly more potent than those of isoprenaline; S-1540 had a very weak action, being only about 1/1000 as active as S-1541. These actions of S-1540 were completely eliminated by propranolol pretreatment. S-1540 induced to remarkable changes in the electrocardiogram wave forms even in high doses. 3) Those drugs elicited the depressor, positive chronotropic and inotropic actions in rabbits and dogs. In rabbits, isoprenaline was most potent; S-1541 was similar to or a little weaker than isoprenaline; and S-1540 was extremely weak. In the dog, isoprenaline showed the highest of the

    Full Text Available Abstract Background Airway narrowing associated with chronic asthma results in the transmission of injurious compressive forces to the bronchial epithelium and promotes the release of pro-inflammatory mediators and the denudation of the bronchial epithelium. While the individual effects of compression or denudation are well characterized, there is no data to elucidate how these cells respond to the application of mechanical compression in the presence of a compromised epithelial layer. Methods Accordingly, differentiated normal human bronchial epithelial cells were exposed to one of four conditions: 1 unperturbed control cells, 2 single scrape wound only, 3 static compression (6 hours of 30 cmH2O, and 4 6 hours of static compression after a scrape wound. Following treatment, wound closure rate was recorded, media was assayed for mediator content and the cytoskeletal network was fluorescently labeled. Results We found that mechanical compression and scrape injury increase TGF-β2 and endothelin-1 secretion, while EGF content in the media is attenuated with both injury modes. The application of compression after a pre-existing scrape wound augmented these observations, and also decreased PGE2 media content. Compression stimulated depolymerization of the actin cytoskeleton and significantly attenuated wound healing. Closure rate was partially restored with the addition of exogenous PGE2, but not EGF. Conclusion Our results suggest that mechanical compression reduces the capacity of the bronchial epithelium to close wounds, and is, in part, mediated by PGE2 and a compromised cytoskeleton.

    It has been considered by modern medicine that bronchial asthma is a chronic airway allergic inflammation (AAI) which is the major factor that induces reversible airway ventilating disturbance and bronchial hyper-responsiveness (BHR) in asthmatic patients, as well as a correlation between the delayed-phase onset of asthma and AAI is more significant than immediate-phase onset of asthma in its pathogenesis. Anti-inflammatory therapy as a fundamental principle of treatment for bronchial asthma has been brought forward during the interval phase so that a large number of anti-AAI drugs to significantly enhance the curative effect such as inhalant corticoid, disodium cromoglycate, and leukotriene receptors antagonist, etc., has been rapidly developed.

    Full Text Available Espasmo hemifacial bilateral é um distúrbio de movimento raro geralmente associado à compressão vascular dos nervos faciais. Caracteriza-se clinicamente por contrações assimétricas e assíncronas da musculatura facial e por longa latência entre a instalação dos movimentos em cada hemiface. Deve ser diferenciado de outras condições como blefaroespasmo, miocimia facial, tiques faciais, distonia oromandibular e espasmo hemimastigatório. O tratamento sintomático mais eficaz e menos invasivo consiste em aplicações de toxina botulínica mas abordagem cirúrgica de descompressão microvascular é outra alternativa terapêutica. Relatamos o caso de homem de 70 anos com espasmo hemifacial bilateral e fazemos uma breve revisão da literatura.Bilateral hemifacial spasm (BHS is a rare focal movement disorder often associated with vascular compression of both facial nerves. The contractions are usually asymmetric and asynchronous. Typically, one side is affected first and there is a long but variable interval for the symptoms on the other side to occur. BHS must be differentiated from other conditions including blefarospasm, facial myokymia, facial tics, oromandibular dystonia, and hemimasticatory spasm. The most successful and non-invasive symtomatic treatment is botulinum toxin injections but microvascular decompression surgery is another therapeutic option. We report the case of a 70 years old man with bilateral hemifacial spasms and present a brief review of the literature.

    A 49-year-old woman with neuromyelitis optica (NMO) developed severe quadriplegia and frequent paroxysmal tonic spasms (PTS). Carbamazepine, although initially effective against PTS, caused drug eruption and she was unable to continue. PTS re-emerged after discontinuation of carbamazepine and hindered rehabilitation. Then topiramate was started, and PTS promptly disappeared. The patient became able to resume rehabilitation and her activity of daily life improved significantly. Carbamazepine and topiramate have a common pharmacological action to block voltage-gated sodium channels. The action may have contributed to inhibition of ephaptic transmission in the demyelinating lesions by NMO and eventually improved PTS.

    Full Text Available Ten adult cats were anesthetized and ventilated by respirator. After the basilar artery was exposed transclivally and visualized with an operative microscope, mean arterial blood pressure (MABP was raised gradually by intravenous drip infusion of norepinephrine (5-20 micrograms/kg or angiotensin-II-amide (0.3-1.0 micrograms/kg. At various blood pressures, microphotographs were taken. There was no appreciable change in vessel diameter at a MABP ranging from 78 to 191 mmHg. The blood pressure was allowed to return to the initial baseline level. Arterial spasm was produced by the topical application of 0.2 M calcium gluconate, which decreased the arterial diameter by 13 to 58 percent for more than 60 min. Blood pressure was increased again after the production of the arterial spasm. Significant increases in the diameter of the arteries were produced by the drug-induced hypertension at levels of MABP ranging from 82 to 192 mmHg. The maximum arterial dilations ranged from 123 to 208 percent of the untreated control. The degree of dilation of the arteries almost paralleled the rise in MABP. Norepinephrine and angiotensin-II had a similar effect on both the blood pressure and the arterial diameter. Induced hypertension would be expected to improve blood flow parameters in the case of spastic cerebral arteries.

    CT scans were obtained in 45 patients with bronchial asthma including 23 patients during asthmatic attack. CT findings were as follows. (1) In all cases, thickening of bronchial wall throughout from central to peripheral bronchi and without tapering and/or slight swelling of bronchovascular bundles were observed. (2) Characteristics findings in 23 patients with asthmatic attack, lobular and multilobular high attenuation area were observed in 17 patients (74%) and nonhomogeneous attenuation in lung fields were noticed in 13 patients (57%). (3) Multiple centrilobular sized high attenuation area were observed in 23 patients, but it was difficult to differenciation whether these findings were due to tiny nodules or to small vessels. In conclusion, further studies are needed to know which pathomorphological and/or pathophysiological conditions are underlying these CT findings. (author)

    Tracheobronchial disruption is uncommon in blunt chest trauma. Many of these patients die before reaching the hospital. In the majority of survivors diagnosis is occasionally delayed resulting in complications like airway stenosis and lung collapse. Thus it is important to have radiological follow up after severe thoracic trauma. Sleeve resection can be an excellent option to conserve lung tissue in delayed presentation of bronchial transection.

    Introduction Temperament, defined as the formal characteristics of behavior, is a personality trait which can influence the clinical presentation and course of bronchial asthma. It determines susceptibility to stress as well as stress coping styles. Aim The aim of the study was to assess whether healthy subjects differ from bronchial asthma patients with regard to temperamental variables and stress coping styles, and whether these factors may also differentiate patients with severe asthma from those with the milder form. The study also assesses whether the results of flow volume curve analysis correlate with temperamental traits and stress coping styles. Material and methods The study was conducted in a group of 65 asthma patients and 62 healthy controls. All underwent flow volume curve examination and psychological tests: Formal Characteristics of Behavior – Temperament Inventory (FCB-TI) and Coping in Stress Situations (CISS) questionnaire. Results Bronchial asthma patients were characterized by a lower level of briskness (“agility”) than healthy subjects (13.35 ±4.48 vs. 14.97 ±3.98, p = 0.031). The remaining temperamental traits and stress coping styles did not differ between the groups. Additionally, the forced expiratory volume in 1 s (FEV1) value was found to correlate negatively with the intensity of the emotion-oriented stress coping style, whereas FEV1 and forced vital capacity (FVC) were found to positively correlate with briskness, emotional reactivity and endurance, while a negative correlation was found with activity. Conclusions Briskness differentiates healthy subjects from bronchial asthma patients. The values obtained in FEV1 and FVC pulmonary function tests were also found to correlate with some temperamental variables. PMID:28035226

    Full Text Available Background: Asthma is a serious public health problem throughout the world and its prevalence has increased in last 2-3 decades. Allergens are one of the many factors which trigger an attack of asthma. Skin prick test is useful in identifying the offending allergen in bronchial asthma. Aim: To identify the possible offending allergens in patients of bronchial asthma. Materials and Methods: The study was a descriptive study conducted at allergy center, Kempegowda Institute of Medical Sciences Hospital and Research Center, Bangalore from January to December 2011. Skin prick test was done in 139 patients suffering from bronchial asthma using 49 allergens extracts. Statistical Analysis: Frequency, proportions, Chi-square test, odds ratio, and 95% confidence interval was used. Results: Out of 139 patients who underwent the skin prick tests, 40% (56 were males and 60% (83 were females. Majority, that is, 60% were in the age group of 21-40 years. Forty-three percent (60 had family history of asthma/atopy, 80% (111 had allergic rhinitis, 24% (34 had chronic urticaria, and 24% (33 had allergic conjunctivitis. Out of 139 patients, 100 (71.94% were sensitive for one or more allergens. The common offending allergens found in the study were dust mites (Dermatophagoides farinae and D. pteronyssinus (DF and DP - 49.28%, dusts - 7.2%, pollens - 6.77%, insects - 6.62%, fungi - 4.53%, and epithelia - 1.92%. Conclusion: The most common allergens in bronchial asthma were dust mites followed by dusts and pollens. Identifying possible allergens in asthma patients help in allergen avoidance and immunotherapy in these patients.

    Botulinum toxin injected into a muscle may diffuse to nearby muscles thus producing unwanted effects. In patients with hemifacial spasm, we evaluated clinically and neurophysiologically, whether botulinum toxin type A (BoNT-A) diffuses from the injection site (orbicularis oculi) to untreated muscles (orbicularis oris from the affected side and orbicularis oculi and oris from the unaffected side). We studied 38 patients with idiopathic hemifacial spasm. Botulinum toxin was injected into the affected orbicularis oculi muscle alone (at 3 standardized sites) at a clinically effective dose. Patients were studied before (T0) and 3-4 weeks after treatment (T1). We evaluated the clinical effects of botulinum toxin and muscle strength in the affected and unaffected muscles. We also assessed the peak-to-peak amplitude compound muscle action potential (CMAP) recorded from the orbicularis oculi and orbicularis oris muscles on both sides after supramaximal electrical stimulation of the facial nerve at the stylomastoid foramen. In all patients, botulinum toxin treatment reduced muscle spasms in the injected orbicularis oculi muscle and induced no muscle weakness in the other facial muscles. The CMAP amplitude significantly decreased in the injected orbicularis oculi muscle, but remained unchanged in the other facial muscles (orbicularis oris muscle on the affected side and contra-lateral unaffected muscles). In conclusion, in patients with hemifacial spasm, botulinum toxin, at a clinically effective dose, induces no clinical signs of diffusion and does not reduce the CMAP size in the nearby untreated orbicularis oris or contralateral facial muscles.

    Background Although benzalkonium chloride (BAC)-induced bronchoconstriction occurs in patients with bronchial asthma, BAC-containing nebulizer solutions are still being used in daily practice in Korea. The aim of this study was to evaluate the effects of inhaled aqueous solutions containing BAC. Methods Thirty subjects with bronchial asthma and 10 normal controls inhaled up to three 600 µg nebulized doses of BAC using a jet nebulizer. FEV1 (forced expiratory volume at one second) was measured 15 minutes after each dose. Inhalations were repeated every 20 minutes until FEV1 decreased by 15% or more (defined as BAC-induced bronchoconstriction) or the 3 doses were administered. Results The percent fall in FEV1 in response to BAC inhalation was significantly higher in asthmatics than in normal subjects (p<0.05). BAC administration in subjects with asthma reached a plateau (maximal effect). BAC-induced bronchoconstriction was found in 6 asthmatics (20%), with two responders after the 2nd inhalation and after the 3rd inhalation. The percent fall in FEV1 in response to the 1st inhalation of BAC was significantly higher in asthmatics with higher bronchial hyperresponsiveness (BHR) than in those with lower BHR. Conclusions This study suggests that the available multi-dose nebulized solution is generally safe. However, significant bronchoconstriction can occur at a relatively low BAC dose in asthmatics with severe airway responsiveness. PMID:18309682

    Full Text Available Objective. We report a rare and unusual case of bronchial carcinoma presenting with symptoms of complications of sinonasal disease. Case Report. A 66-year-old lady was referred with a 1-week history of progressive ocular pain, chemosis, and visual disturbance. Computed tomography of the paranasal sinuses revealed frontal and ethmoidal sinus opacification with orbital involvement consistent with a diagnosis of orbital cellulitis secondary to sinusitis. Surgical exploration revealed that the sinuses and right orbit were filled with soft tissue and subsequent histopathological examination of the biopsies indicating metastases from an adenosquamous bronchial carcinoma. Further imaging revealed a large, asymptomatic, bronchial primary with deposits in the brain and liver. The advanced presentation of the disease limited treatment to best supportive care. Conclusion. Orbital cellulitis and sinonasal malignancies have a similar pattern of clinical presentation, posing a potential diagnostic pitfall. There are only two previously reported cases of metastatic lung carcinoma in the frontal sinus with 15 cases of sinonasal tract involvement reported overall. There are no reported cases of adenosquamous carcinoma in the sinonasal tract.

    For investigation of a possible relationship between cutaneous and bronchial hyperreactivity, 74 subjects were grouped according to the presence (n = 33) or absence (n = 41) of urticarial dermographism after application of a standardized shearing pressure with a dermographometer (12.7 x 10(5) Pa). the two groups did not differ in age, sex, smoking habits, presence of urticaria and atopy, or serum IgE levels. Erythema of the dermographic test sites was always significantly greater (P dermographism at 2, 4, and 8 min, and cutaneous reactivity with titrated prick tests was significantly increased in this group with low concentrations of histamine, 0.01% and substance P (0.25 mM) (P dermographism, exhibited bronchial hyperreactivity. However, significantly more subjects with urticarial dermographism had an increase in airway resistance and a decrease in specific airway conductance (P dermographism (urticaria factitia), these differences were even more significant (P < 0.001). These subjects also had larger skin test reactions and significantly higher IgE levels (P < 0.01). Thus, the present data show an association, which may be based on common mechanisms of allergic inflammation, between cutaneous and bronchial hyperreactivity.

    This report deals with the usefulness of three-dimensional (3D) display for microvascular decompression surgery in patients with hemifacial spasm and trigeminal neuralgia. Twenty-two patients with hemifacial spasm and six with trigeminal neuralgia were studied by magnetic resonance (MR) imaging using three-dimensional spoiled gradient recalled acquisition in the steady state (3D-SPGR), MR angiography and 3D display. The 3D displayed images were roconstructed at a work station from the 3D-SPGR MR data by the surface rendering method. In all patients, the preoperative 3D-SPGR MR images demonstrated the causative vessels that had been compressed or were attached to the root exit or root entry zone (REZ) of the facial or trigeminal nerve. The causative vessels were identified on MR angiography. The 3D display provided clear information regarding the anatomical relationship between the causative vessels and the REZ of the nerves. Among the 22 patients with hemifacial spasm, the causative vessels were the posterior inferior cerebellar arteries (PICA) in 11, and the anterior inferior cerebellar arteries in the other 11. In the six patients with trigeminal neuralgia, the causative vessels were identified as the superior cerebellar arteries in five, and PICA in the remaining one. The surgical findings were compatible with those demonstrated by 3D displayed images. The symptoms were completely relieved after surgery in 20 patients with hemifacial spasm and in all six patients with trigeminal neuralgia. In conclusion, 3D-SPGR MR imaging and MR angiography are useful for the detection of the causative vessels in patients with hemifacial spasm and trigeminal neuralgia. Moreover, 3D display is especially useful for the presentation of the anatomical relationship and the simulation of surgical procedures. (author)

    Stiff limb syndrome (SLS) is a rare chronic condition which can result in significant debility. We report the case of a 44-year-old man suffering from severe painful spasms in his right leg with a diagnosis of SLS. He had been initially treated for his pain with a spinal cord stimulator but presented with exacerbation of pain secondary to a lead fracture for which he underwent revision of the stimulator. Postoperative programming unexpectedly resulted in not only control of his pain but also an ability to abort his spasmodic episodes related to SLS. To our knowledge, spinal cord stimulation has not been previously used for SLS and our report opens up another avenue for this rare condition. We provide a brief overview of SLS and propose an underlying mechanism for the observed phenomenon.

    Aicardi syndrome is defined by the clinical triad of infantile spasms, agenesis of the corpus callosum, and pathognomonic chorioretinal lacunae. Almost all patients are females with severe cognitive and physical disabilities. All of the cases reported in the literature have had early-onset seizures. Most cases of Aicardi syndrome exhibit very slow development, even when seizures are eventually controlled, and the cases with a relatively favourable outcome are associated with low intelligence quotient levels. A relationship between chorioretinal changes or severity of the agenesis of the corpus callosum and prognosis of Aicardi syndrome has been claimed, but few data are available about the clinical features that can predict clinical outcome. We describe a case of Aicardi syndrome in a female aged 24 months. Magnetic resonance imaging showed complete agenesis of the corpus callosum and ophthalmoscopy revealed chorioretinal lacunae in the left eye. She had never had seizures and her psychomotor and language development were normal for age.

    SLC1A4 deficiency is a recently described neurodevelopmental disorder associated with microcephaly, global developmental delay, abnormal myelination, thin corpus callosum and seizures. It has been mainly reported in the Ashkenazi-Jewish population with affected individuals homozygous for the p.Glu256Lys variant. Exome sequencing performed in an Irish proband identified a novel homozygous nonsense SLC1A4 variant [p.Trp453*], confirming a second case of SLC1A4-associated infantile spasms. As this is the first European identified, population ancestry analysis of the Exome Aggregation Consortium database was performed to determine the wider ethnic background of SLC1A4 deficiency carriers. p.Glu256Lys was found in Hispanic and South Asian populations. Other potential disease-causing variants were also identified. Investigation for SLC1A4 deficiency should be performed regardless of ethnicity and extend to include unexplained early-onset epileptic encephalopathy.

    Tissue expander-based breast reconstruction is the most commonly utilized technique in the U.S. This modality, however, may be associated with significant pain related to pectoralis myospasms. Spasms of the pectoralis major likely result from trauma to the pectoral nerves during muscle elevation. In a subset of patients, Botox(®) therapy may be inadequate for long-term relief. We describe a patient with intractable pectoralis myospasms after breast reconstruction. Upon failing Botox(®) therapy, medial and lateral pectoral neurectomies were performed. Nine months after the procedure, the patient noted dramatic improvement in both symptoms and cosmesis with no musculoskeletal sequelae. We recommend medial and lateral pectoral neurectomy as an alternative in patients with intractable pectoral myospasms after tissue expander reconstruction.

    Full Text Available There is no published registry for drug-induced acute myocardial infarction (AMI with subsequent patent coronary angiogram in teenagers. To highlight the mechanism and impact of drug-induced MI with patent coronary arteries among teenagers who have relatively few coronary risk factors in comparison with older patients, we conducted a review of the literature. In this review most of the pertinent published (English and non-English articles through the Medline, Scopus, Cochrane Database of Systematic Reviews, and EBSCO Host research databases from 1970 to 2005 have been revised. Teenagers and young adults with AMI and subsequent patent coronary angiogram were included. In those cases drug-induced coronary spasm was highlighted. Among 220 articles (>12000 cases related with AMI with normal coronary angiogram, 50 articles (~100 cases reported the role of drug in AMI secondary to coronary artery spasm (CAS. There is no well-conducted trial for AMI secondary to CAS in young adults but only a series of case reports, and the diagnosis in most of cases was based on the clinical and laboratory findings without provocation. CAS was associated with 12 illicit substances in teenagers (i.e., cocaine, marijuana, alcohol, butane, and amphetamine. Smoking is not only the initiative but also might harbor other illicit substances that increase the risk for CAS. Cocaine-associated AMI is the most frequent in various research papers. CAS was reported with 19 types of medications (i.e., over-the-counter, chemotherapy, antimigraine, and antibiotics without strong relation to age. Despite drug-induced AMI being not a common event, attention to smoking and drugs in teenagers and young adults will have major therapeutic and prognostic implications.

    Mood, anxiety, and other psychological symptoms are common in dystonic patients suffering from blepharospasm (BSP) and spasmodic torticollis (ST). Since sexual well-being is an important aspect of mental health, here, we investigated whether these patients may also experience a worsening of their sexual life. In particular, quality of sexual life was evaluated in patients suffering from BSP (N = 30), ST (N = 30), and in a control group of patient with Hemifacial spasm (HFS; N = 30), undergoing botulinum toxin type A therapy. A group of 30 age-matched healthy volunteers constituted an additional control group. Patients were evaluated just before the periodic injection of botulinum toxin. Sexual functioning was assessed using the Sexual Functioning Inventory, a reduced form of the Golombok Rust Inventory, previously employed in patients with Parkinson's disease. Depression (Beck Depression Inventory) and anxiety (STAI-X1/X2) were also assessed. Results revealed that sexual functioning was significantly affected in patients with BSP, ST, and HFS with respect to healthy controls. Dystonic patients manifested more sexual dysfunction than patients with HFS. Overall, females had a poorer quality of sexual life than males and, among females, women with BSP were the most dysfunctional. Psychological symptoms were present in patients with dystonia, but not in patients with HFS. As discussed in the paper, several factors might be taken into account to explain worse quality of sexual life in patients with dystonia compared to patients with hemifacial spasm. Among them an important role might be played by the central origin of dystonia pathophysiology (i.e., altered activity of cortico-striato-thalamic-cortical circuits). Future investigations are necessary to further explore these preliminary findings, considering that this is the first time that sexual well-being is evaluated in patients with BSP, ST, and HFS, and comparable data are not available.

    Introduction Pharyngoesophageal spasm (PES) can cause dysphagia, central valve leak (CVL), and dypshonia in post-laryngectomy patients. Botulinum toxin has been used effectively for the treatment of PES, but data regarding patient-reported outcomes and efficacy for CVL are limited. We evaluated the results of botox injection for PES spasm using subjective and objective measures. Methods Data were collected prospectively (February 2010 to August 2013) on 13 patients undergoing botox injection for PES as identified by video fluoroscopy. We collected digital voice recordings, air-pressure measurements (APMs) for speech, and quality of life (QoL) data before and after the procedure: University of Washington QoL questionnaire (UW-QoL), MD Anderson Swallowing Inventory (MDADI) and the Voice Handicap Index (VHI-30). Results APMs for a sustained vowel decreased by 18% after botox injection, whereas maximum phonatory times increased by 63% (mean increase, 8 to 13 seconds). Sustained vowel amplitude decreased (mean, 87db to 83db) with an associated reduction in sustained vowel frequency (117Hz to 77Hz). MDADI scores improved by 10.2% overall, and UW-QoL scores showed an improvement in score of 7.6%. Mean scores for VHI-30 deteriorated by 2% overall but, when considering only those patients experiencing dysphonia, an improvement of 9.4% was seen. There was an overall net reduction for the CVL cohort of 12 speech valves in the year after injection. Conclusions Our series confirm the safety and objective efficacy of botox injection for PES. QoL measurements were less convincing, and this disparity between subjective and objective measurements must be considered when treating such patients. PMID:26414361

    Background Infantile spasms is a severe epileptic encephalopathy,which is refractory to conventional antiepileptic drugs.Adrenocorticotropic hormone (ACTH) has been the major therapy for infantile spasms;however,ACTH therapy is ineffective for some patients.The variations in the receptor genes can contribute to antiepileptic drug resistance.This study was to elucidate the possible associations between the variations of the MC2R gene and ACTH responsiveness in patients with infantile spasms.Methods We screened for variations in the promoter and coding region of the MC2R gene in 91 Chinese patients with infantile spasms and 94 controls,using PCR and a direct sequencing method.The frequencies of the genotypes,alleles and reconstructed haplotypes were analyzed in the cases and controls.The association between ACTH responsiveness and genetic variations of the MC2R gene was also assessed.Results Four single nucleotide polymorphisms (SNPs) were identified in the MC2R promoter,one of which was a novel specimen at position-2 from the transcription start site ATT,-2T>C.Three SNPs (rs1893220,rs2186944 and -2T>C)showed a significant difference between the cases and controls (P<0.05 for all).The frequency of the common TCCT haplotype carrying four-SNP major alleles was significantly lower in the cases (39%) than in the controls (60%)(P=0.00003).The homozygous carriers of the TCCT haplotype had a much lower relative risk than the non-carriers (RR=0.42,95%CI 0.26-0.70,P=0.0001).ACTH responsiveness was strongly associated with the TCCT haplotype (P=0.000082).Compared with non-carriers of the TCCT haplotype,the homozygous and heterozygous carders were more responsive to ACTH therapy (P=0.0002;P=0.0003,respectively).Conclusions Our results indicated that the TCCT haplotype in the MC2R promoter is strongly associated with the responsiveness of the ACTH therapy performed on patients with infantile spasms.The polymorphisms of the MC2R promoter might be one important factor that

    Coronary to bronchial artery fistula is a rare vascular anomaly secondary to enlargement of pre-existing vascular anastomosis between the coronary and bronchial arteries. This occurs when there is a constant disturbance of the pressure equilibrium involving either coronary or broncho-pulmonary disorder. Localized bronchiectasis is the most common related condition in patients with a coronary to bronchial artery fistula. Herein, we report on a case of a large left circumflex coronary artery to right bronchial artery fistula associated with bronchiectasis.

    Objective To study the role of eotaxin and eotaxin-2 expression by Th2 cytokine and analyze their relationship in normal human bronchial epithelial cell line-BEAS-2B cell. Methods Levels of eotaxin mRNA and protein expression in the bronchial epithelial cell line BEAS-2B cell were determined with RT-PCR and ELISA. We also used RT-PCR to evaluate eotaxin-2 expression under the regulation of Th2 cytokine IL-4 and IL-13 as well as proinflammatory agent-TNFα. Results Eotaxin mRNA expression was the highest at the time point of 12h under the stimulation of TNF-α. While Th2 cytokine IL-4 and IL-13 had the amplification effect on the expression. Eotaxin protein was also elevated with the combination stimulation of proinflammatory agent TNF-α and IL-4 in dose and time dependent manner(P<0.01). These results were also seen when the cells were stimulated by TNF-α and IL-13. Eotaxin-2 mRNA expression was the highest at the time point of 8h. The expression evaluated by semi-quantitative RT-PCR also elevated under the co-stimulation of TNF-α and IL-4 or TNF-α and IL-13 and it should significantly correlate with Eotaxin(P<0.05). Conclusion This study demonstrated that Th2 cytokine like IL-4 and IL-13 enhances eotaxin and eotaxin-2 expression when co-stimulated with proinflammatory agent TNF-α. These results showed that Th2 cytokines existence is the strong evidence for bronchial epithelial cells taking part in the allergic inflammation especially in eosinophils recruitment.

    Typhoid fever is an enteric infection caused by Salmonella typhi. In Indonesia, typhoid fever is endemic with high incidence of the disease. In daily practice we frequently have patients with bronchial asthma, and it is becoming worse when these patients get typhoid fever. After oral ingestion, Salmonella typhi invades the the intestine mucosa after conducted by microbial binding to epithelial cells, destroying the microfold cells (M cell) then passed through the lamina propria and detected by dendritic cells (DC) which express a variety of pathogen recognition receptors on the surfaces, including Toll-Like Receptor (TLR). expressed on macrophages and on intestinal epithelial cells inducing degradation of IB, and translocation of NF-B (Nuclear Factor-Kappa Beta). This process initiates the induction of pro-inflammatory gene expression profile adhesion molecules, chemokines, adhesion molecules, and other proteins that induce and perpetuate the inflammation in host cells then will induce acute ant intractable attack of bronchial asthma. The role of typhoid fever in bronchial asthma, especially in persons with acute attack of bronchial asthma, is not well understood. In this article, we will discuss the role of typhoid fever in the bronchial asthma patients which may cause bronchial asthma significantly become more severe even triggering the acute and intractable attack of bronchial asthma. This fact makes an important point, to treat completely the typhoid fever in patients with bronchial asthma.

    Although models of branching in arterial and bronchial trees often predict a dependence of bifurcation parameters on the scale of the bifurcating vessels, direct verifications of this dependence with data are uncommon. We compare measurements of bifurcation parameters in airways and arterial trees of different mammals as a function of scale to general features predicted by theoretical models. We find that the size dependence is more complex than existing theories based solely on energy minimization explain, and suggest additional factors that may govern the branching at different scales.

    Lung transplantation has resulted in dramatic functional improvement in patients with end-stage pulmonary diseases. Among the complications of lung transplantation are dehiscence and stenosis at the site of the bronchial or tracheal anastomosis. In this case report, we describe a single lung transplant recipient in whom partial bronchial dehiscence, followed by exuberant growth of granulation tissue, resulted in obstruction of the bronchial lumen. After mechanical dilation failed to produce lasting relief of bronchial obstruction, a novel approach to this problem was successfully employed: YAG laser phototherapy was used to remove obstructing granulation tissue, followed by application of a preparation derived from autologous blood platelets to promote epithelialization of the bronchial anastomosis. The bronchus remains patent and fully epithelialized six months after therapy.

    A 53-year-old man with a history of blood transfusion at the age of 20 was admitted to our hospital because of liver dysfunction. He had bronchial asthma when he was 18 years old, which naturally resolved within 2 years. However, his bronchial asthma recurred at the age of 45 and was treated with oral theophylline. He was diagnosed as having chronic hepatitis C based on the histological and clinical findings, and then interferon (IFN) therapy was administered. The frequency of bronchial asthma attack was gradually decreasing after IFN therapy with marked improvement of hypereosinophilia. He achieved sustained viral response (SVR) and his bronchial asthma did not worsen even after the cessation of IFN. Hepatitis C virus (HCV) infection and IFN therapy were considered in the remission of asthma in this case. HCV infection could be the cause of bronchial asthma, especially in patients with late appearance of asthma.

    Objectives During microvascular decompression (MVD) of the facial nerve for hemifacial spasm (HFS), an abnormal muscle response can be recorded upon stimulation of the facial nerve, also known as the lateral spread response. This response may vanish after MVD and has been associated with a successful outcome. The purpose of this study was to determine if resolution of lateral spread correlated with the elimination of HFS in a single surgeon's experience.

    Full Text Available This review focuses on the methods available for measuring reversible airways obstruction, bronchial hyperresponsiveness (BHR and inflammation as hallmarks of asthma, and their role in monitoring children with asthma. Persistent bronchial obstruction may occur in asymptomatic children and is considered a risk factor for severe asthma episodes and is associated with poor asthma outcome. Annual measurement of forced expiratory volume in 1 s using office based spirometry is considered useful. Other lung function measurements including the assessment of BHR may be reserved for children with possible exercise limitations, poor symptom perception and those not responding to their current treatment or with atypical asthma symptoms, and performed on a higher specialty level. To date, for most methods of measuring lung function there are no proper randomised controlled or large longitudinal studies available to establish their role in asthma management in children. Noninvasive biomarkers for monitoring inflammation in children are available, for example the measurement of exhaled nitric oxide fraction, and the assessment of induced sputum cytology or inflammatory mediators in the exhaled breath condensate. However, their role and usefulness in routine clinical practice to monitor and guide therapy remains unclear, and therefore, their use should be reserved for selected cases.

    Full Text Available This study was performed to assess the effectiveness of acupuncture and medical therapies of bronchial asthma preoperatively. Sixty patients suffered from mild to moderate bronchial asthma and coming for elective operations were chozen from the outpatient clinic of Al-Zahraa University Hospital. Patients were randomly divided into three equal groups (n=20 each. Group I patients (drug group received oral theophylline and Salbutamol (ventolin inhaler according to the needs. Group II patients (drug +ear acupuncture group received same medical treatment as in group I and added ear acupuncture. Group III patients (drug + ear and body acupuncture group received same medical treatment as in group I and II and added ear and body acupuncture. Ventilatory function tests through spirometer and interleukin-13 estimation were performed before treatment and after two weeks of treatment. Improvement of subjective and objective parameters had occurred with significant decrease in the mean serum level of interleukin-13 and decrease in the mean number of using b-agonist puffs after two weeks of treatment in the three groups, with the best results being in group III than in group II and then in group I. Conclusion: Interleukin-13 estimation togheter with ventilatory function tests is a useful parameter for pre-operative assessment and evaluation of asthmatic patients. Also medication was significantly reduced when combined with acupuncture.

    Full Text Available Forty-four patients with allergic (ABA and non-allergic (NABA variants of bronchial asthma (BA were examined to evaluate levels of key adipokines (leptin, resistin, adiponectin in sputum in different variants of BA. Adipokines in sputum and blood plasma were measured by Enzyme-Linked Immunosorbent Assay (ELISA. The indices that reflect the percentage of adipokines in sputum regarding adipokines in plasma of the same patients were worked out to evaluate the ratio of levels of corresponding adipokines in plasma and sputum in patients with BA. Two regularities are clearly seen in the study: the first - levels of proinflammatory adipokines (leptin, resistin in sputum in ABA correlate directly with indicators of respiratory function but levels of anti-inflammatory adipokines (adiponectin in sputum correlate inversely with indicators of respiratory function; the second -correlation of levels of the studied adipokines with indicators of respiratory function are almost not revealed in NABA. The first regularity reflects the important fact that the content of adipokines in bronchial secretion is to a certain extent one of regulating local mechanisms in target organ controlled system levels of corresponding adipokines in exacerbation of BA.

    Gastro-bronchial fistula (GBF) is an unusual complication of Nissen fundoplication, particularly when performed via a transabdominal approach. The mechanism of such fistula is thought to be related to a previously untreated ulcer in the mucosa of the wall of the gastric wrap or to a subclinical injury to the gastric wall during the process of division of the short gastric vessels and gastric mobilization. This process is greatly aided by herniation of the wrap into the chest in the postoperative period, placing the stomach in intimate contact with the bronchial tree. The diagnosis of GBF is often difficult to establish and requires a high index of suspicion. Most investigative studies tend to be unrevealing. Historically, an upper gastrointestinal series was the recommended study of choice in the literature. Newer reports, however, highlight the value and importance of upper endoscopy as a diagnostic tool in this condition. The majority of GBF were reported in the era of transthoracic Nissen fundoplication. The incidence of this complication seems to have markedly decreased after the widespread adoption of the transabdominal approach to the treatment of GERD. We are reporting the second case in the literature of a GBF developing after a laparoscopic Nissen fundoplication in a 28-year-old male patient. This case report should serve to increase awareness of this uncommon complication that should be considered in the differential diagnosis of patients with recurrent pneumonia or refractory hemoptysis after major upper gastrointestinal surgical procedures.

    Full Text Available Airway epithelial mucus hypersecretion and mucus plugging are prominent pathologic features of chronic inflammatory conditions of the airway (e.g. asthma and cystic fibrosis and in most of these conditions, women have worse prognosis compared with male patients. We thus investigated the effects of estradiol on mucus expression in primary normal human bronchial epithelial cells from female donors grown at an air liquid interface (ALI. Treatment with estradiol in physiological ranges for 2 weeks caused a concentration-dependent increase in the number of PAS-positive cells (confirmed to be goblet cells by MUC5AC immunostaining in ALI cultures, and this action was attenuated by estrogen receptor beta (ER-β antagonist. Protein microarray data showed that nuclear factor of activated T-cell (NFAT in the nuclear fraction of NHBE cells was increased with estradiol treatment. Estradiol increased NFATc1 mRNA and protein in ALI cultures. In a human airway epithelial (1HAE0 cell line, NFATc1 was required for the regulation of MUC5AC mRNA and protein. Estradiol also induced post-translational modification of mucins by increasing total fucose residues and fucosyltransferase (FUT-4, -5, -6 mRNA expression. Together, these data indicate a novel mechanism by which estradiol increases mucus synthesis in the human bronchial epithelium.

    Hemoptysis can be a life-threatening pulmonary emergency with high mortality, is symptomatic of an underlying severe pulmonary disease and requires immediate diagnosis and treatment. Diagnostically, bronchoscopy, conventional chest x-ray and contrast-enhanced multislice computed tomography (MSCT) with CT angiography (CTA) provide information regarding the underlying pulmonary disease, bleeding site, the vascular anatomy of the bronchial arteries (BA) and extrabronchial branches, as well a basis for planning of endovascular intervention. Therapeutically, bronchial artery embolization (BAE) is a safe and effective technique in the hands of an experienced interventionist with profound knowledge of the BA anatomy and possible pitfalls as well as experience with first-line therapy of recurrent and massive hemoptysis or as an intervention prior to elective surgery. Recurrent episodes of hemoptysis are not uncommon and require a prompt repeat BAE after exclusion of extrabronchial systemic and pulmonary artery bleeding sources. This review article should give an overview of the history, anatomical and pathophysiological basics and the clinical context of hemoptysis and diagnosis, as well as a survey of management, treatment and results of BAE.

    Vagoglossopharyngeal neuralgia (VGPN) is a very rare condition. VGPN with convulsive like attack is even rarer All of the cases had their head turned to the opposite side of facial pain. Hemifacial spasm occurring concurrently with VGPN has never been reported. Herein, we present the first case of VGPN that had ipsilateral hemifacial spasm and versive seizure-like movement to the same side of facial pain. We reported a 71-year-old man presenting with multiple episodes of intermittent sharp shooting pain arising on the right middle neck, followed by hemifacial spasm on right face. Then the patient became syncope while his head and gaze turned to the same side of the painful neck. Electrocardiography showed sinus arrest. Interictal Electroencephalography was normal. This patient initially responded to pregabalin for two weeks, then the symptoms became worse. Microvascular decompression and carbamazepine resulted in the complete remission of all symptoms after six months of follow-up. We could not explain the pathophysiology of unilateral versive seizure like movement.

    Objective To confirm and compare the therapeutic efficacies of CBTX-A (made by Lanzhou Biological Products Institute, China) and Botox (from Allergan Inc, US) for focal dystonia and other neurological disorders characterized by involuntary or abnormal muscle contractions. Methods We treated 785 patients with medically intractable focal dystonia and muscle spasm in two groups, 192 cases with Botox and 593 cases with CBTX-A. A total of 1393 treatments were given over a 4-year period. The results of a prospective open study were analyzed. Results Considerable improvement of symptoms was observed in all patients but 11 (1.4%)with either Botox or CBTX-A, 30.4% were rated as excellent, 57.8% as marked improvement, 8.9% as moderate improvement. The side effects were usually minor and transient. The most concerned complications after injections were ptosis and dysphagia. There was no significant difference in the clinical effects between this two kinds off preparation, including the latency of response, maximal benefit, duration of improvement. Patients' subjective assessments were similar too. But the requested dose of Chinese preparation which produced the similar effects was statistically higher than that of Botox; and skin rash appeared within a few days after injections in 5 cases of CBTX-A group, while none of Botox group, no statistical differences in the other adverse reaction between them. Treatment was needed to repeat in most patients to maintain the effects. The pretreatment scores of the reinjection were slightly lower. Moreover, a progressive reduction in posttreatment scores was observed in HFS and CD, with the latency of response, duration ofimprovement and doses unchanged or doses lower than the initial one. Conclusion The injections of both two kinds of preparation were simple and effective out-patient treatment for the patients with focal dystonia and muscle spasm. Chinese preparation is a little less powerful but much cheaper than Botox. Although a few

    Background Radial artery spasm (RAS) is the most common complication in transradial coronary angiography and intervention. In this study, we designed to investigate the incidence of RAS during transradial procedures in Chinese, find out the independent predictors through multiple regression, and analyze the clinical effect of RAS during follow-up. Methods Patients arranged to receive transradial coronary angiography and intervention were consecutively enrolled. The incidence of RAS was recorded. Univariate analysis was performed to find out the influence factors of RAS, and logistic regression analysis was performed to find out the independent predictors of RAS. The patients were asked to return 1 month later for the assessment of the radial access.Results The incidence of RAS was 7.8% (112/1427) in all the patients received transradial procedure. Univariate analysis indicates that young (P=0.038), female (P=0.026), small diameter of radial artery (P 3) (P=0.048), rapid baseline heart rate (P=0.032) and long operation time (P=0.021) were associated with RAS. Logistic regression showed that female (OR=1.745, 95% CI: 1.148-3.846, P=0.024), small radial artery diameter (OR=4.028, 95%CI: 1.264-12.196, P=0.008), diabetes (OR= 2.148, 95%CI: 1.579-7.458, P=0.019) and unsuccessful access at first attempt (OR=1.468, 95%CI: 1.212-2.591, P=0.032) were independent predictors of RAS. Follow-up at (28±7) days after the procedure showed that, compared with non-spasm patients, the RAS patients had higher portion of pain (11.8% vs. 6.2%, P=0.043). The occurrences of hematoma (7.3% vs. 5.6%, P=0.518) and radial artery occlusion (3.6% vs. 2.6%, P=0.534) were similar. Conclusions The incidence of RAS during transradial coronary procedure was 7.8%. Logistic regression analysis showed that female, small radial artery diameter, diabetes and unsuccessful access at first attempt were the independent predictors of RAS.

    Full Text Available Objective To investigate the significance of abnormal muscle response (AMR monitoring during microvascular decompression (MVD for hemifacial spasm (HFS in confirming the responsible blood vessel, improving the prognosis and reducing postoperative complications.  Methods A total of 34 HFS patients underwent AMR monitoring during MVD.  Results The AMR of mentalis was recorded in all 34 patients by electrically stimulating zygomatic branch of facial nerve before anesthesia. Compared with preoperation, the AMR latency after operation was significantly longer [(16.12 ± 3.17 ms vs (14.75 ± 3.32 ms, P = 0.015] and amplitude was significantly reduced [(0.11 ± 0.03)mV vs (0.13 ± 0.03 mV, P = 0.027]. AMR was disappeared in 32 cases (94.12% after the removal of responsible blood vessel. There was one patient (2.94% whose AMR disappeared momentarily after the incision of endocranium and disappeared completely after the removal of responsible blood vessel, while AMR still existed in one case (2.94% after the removal of responsible blood vessel. Responsible blood vessels included anterior inferior cerebellar artery (N = 30, 88.24%, posterior inferior cerebellar artery (N = 3, 8.82% and basilar artery (N = 1, 2.94%, which oppressed the root of facial nerve (N = 22, 64.71%, the distal part (N = 8, 23.53%, and both the root and distal part (N = 4, 11.76%. After operation, facial spasm disappeared. Thirty-one cases were cured, 2 cases evidently remitted, and one case inefficacious. The total effective rate was 97.06%.  Conclusions Continuously intraoperative monitoring of AMR contributes to confirming the responsible blood vessel, completing decompression for facial nerve more thoroughly, improving the prognosis, reducing delayed healing up, at the same time enhancing neurosurgeons' confidence and reducing operation time. DOI: 10.3969/j.issn.1672-6731.2016.05.010

    The assessment of airway dimensions in patients with airway disease by using computed tomography (CT) has been limited by the obliquity of bronchi, the ability to identify the bronchial generation, and the limited number of bronchial measurements. The aims of the present study were (i) to analyze cross-sectional bronchial dimensions after automatic orthogonal reconstruction of all visible bronchi on CT images, and (ii) to compare bronchial morphometry between smokers and nonsmokers. CT and pulmonary function tests were performed in 18 males separated into two groups: 9 nonsmokers and 9 smokers. Bronchial wall area (WA) and lumen area (LA) were assessed using dedicated 3D software able to provide accurate cross-sectional measurements of all visible bronchi on CT. WA/LA and WA/(WA+LA) ratios were computed and all parameters were compared between both groups. Smokers demonstrated greater WA, smaller LA, and consequently greater LA/WA and LA/(WA+LA) ratios than nonsmokers. These differences occurred downward starting at the fourth bronchial generation. 3D quantitative CT method is able to demonstrate significant changes in bronchial morphometry related to tobacco consumption.

    Bronchial asthma and diabetes mellitus type 2 are often found among adult patients. However, coincidence of these two diseases is very rare. The aim of the study was the retrospective analysis of all patients with bronchial asthma and diabetes mellitus type 2 hospitalised in Department and Clinic of Internal Diseases and Allergology in Zabrze, Silesian School of Medicine in Katowice in 1988-1997. Diabetes mellitus type 2 was diagnosed according to WHO criteria of 1985 and bronchial asthma was diagnosed with the use of American Thoracic Society criteria. Bronchial asthma and diabetes mellitus type 2 occurring together were found in 18 patients (0.3% of all hospitalized patients). In most patients the symptoms of bronchial asthma preceded the diagnosis of diabetes mellitus by a few years. All these cases were heterogeneous in terms of the duration of the diseases, clinical picture, and therapeutical approaches. In patients with bronchial asthma the existence of diabetes mellitus type 2 was not related to use of glikocorticosteroids. Patients in whom the coexistence of bronchial asthma and diabetes mellitus type 2 was found should be subjects of further studies to extend our knowledge of patomechanism of these diseases.

    Studies have shown that eosinophils are closely related to pathogenesis of bronchial asthma. Eosinophils release eosinophil cationic protein (ECP), which plays an important role in infection and allergic reactions. Serum ECP mRNA expression in children with bronchial asthma has not been adequately investigated. We analyzed serum ECP mRNA expression in 63 children with bronchial asthma and 21 healthy children by using reverse-transcriptase polymerase chain reaction to understand the role of ECP in children with bronchial asthma. The children with bronchial asthma were segregated into acute-phase and stable-phase groups, based on the severity of the illness. Serum ECP mRNA expression in children with bronchial asthma (0.375 ± 0.04) was significantly higher than that in healthy controls (0.20 ± 0.02; P children in the acute-phase group showed higher ECP mRNA expression level (0.44 ± 0.06) than those in the stable-phase (0.31 ± 0.03) and healthy control groups (0.20 ± 0.02; P children with bronchial asthma.

    Apparent brain atrophy has been frequently observed at CT and MRI after ACTH therapy in patients with infantile spasms. There are several hypotheses to explain ACTH-induced brain shrinkage: 1) a catabolic effect of ACTH on brain tissue, 2) a mineralocorticoid effect resulting in a loss of water and 3) an increase in cerebrospinal fluid (CSF) pressure compressing the brain. An average of 0.21 +/- 0.03 mg/kg of ACTH was administered to nine patients over a period of 14 to 17 days. Water content and concentrations of N-acetylaspartate (NAA), creatine and phosphocreatine (Cr + PCr), and choline (Cho) were measured before, immediately after, and several months after the ACTH therapy by using in-vivo 1H magnetic resonance spectroscopy (MRS). Only NAA concentration exhibited a significant change during the study (6.6 +/- 1.5 mmol/kg, 5.4 +/- 1.1, and 7.0 +/- 1.5, p = 0.017). There was no significant change in Cr + PCr, in Cho, or in water content. These data suggest catabolic effects of ACTH on brain tissue, such as cell loss, decrease in NAA synthesis in mitochondria, and leakage of NAA from cell membrane.

    Facial asymmetry is found in patients with or without cosmetic facial alterations. Some patients have facial asymmetry that manifests underlying skeletal problems, while others have only limited soft-tissue facial asymmetry. Orthognathic surgery brings about a dermatic change, as soft tissue covers underlying bones. Limited soft-tissue asymmetry, meanwhile, is difficult to correct. The treatment modalities for the creation or restoration of an esthetically pleasing appearance were autogenous fat grafts, cartilage graft, and silicon injections. A young female patient had right-side facial asymmetry. The clinical assessment involved visual inspection of the face and palpation to differentiate soft tissue and bone. Although the extra-oral examination found facial asymmetry with skin atrophy, the radiographic findings revealed no mandibular atrophy or deviation. She was diagnosed as localized scleroderma with muscle spasm. In conclusion, facial asymmetry patients with skeletal asymmetry can be esthetically satisfied by orthognathic surgery; however, facial atrophy patients with skin or subdermal tissue contraction need treatment by cosmetic dermatological surgery and orthodontic correction.

    Full Text Available Primary hemifacial spasm (HFS is characterized by irregular and involuntary contraction of the muscles innervated by the ipsilateral facial nerve. Treatment controls symptoms and improves quality of life (QoL. Objective : Evaluate the initial diagnosis and treatment of HFS prior to referral to a tertiary center. Method : We interviewed through a standard questionnaire 66 patients currently followed in our center. Results : Mean age: 64.19±11.6 years, mean age of symptoms onset: 51.9±12.5 years, male/female ratio of 1:3. None of the patients had a correct diagnosis in their primary care evaluation. Medication was prescribed to 56.8%. Mean time from symptom onset to botulinum toxin treatment: 4.34 ±7.1 years, with a 95% satisfaction. Thirty percent presented social embarrassment due to HFS. Conclusion : Despite its relatively straightforward diagnosis, all patients had an incorrect diagnosis and treatment on their first evaluation. HFS brings social impairment and the delay in adequate treatment negatively impacts QoL.

    We describe the case of an eight-year-old girl with complaints of headaches and blurred vision (uncorrected visual acuity: 0.1 decimal) that showed on examination miotic pupils, pseudomyopia, no ocular motility restrictions, and no associated neurological disease. After initial treatment with cyclopentolate for two months, pseudomyopia persisted with an intermittent and variable esotropia. Spectacles of +1 both eyes and atropine 1% one drop daily were then prescribed. The situation improved and remained stable for several weeks, with pseudomyopia and esotropia reappearing later. Finally, botulinum toxin (2.5 iu Botox) was injected in the medial rectus muscle on two occasions and a visual therapy program based on the stimulation of fusional divergence, diplopia, and stereopsis consciousness was recommended. This prescription was combined with the use of atropine during the first few weeks. Orthotropia and corrected distance visual acuity of 1.0 were found three months after treatment. The evolution and clinical results of this case report suggest that botulinum toxin in combination with other therapeutic alternatives may be useful in the treatment of spasm of the near reflex.

    We present a case of a 71-year-old male who hadchest symptoms at rest and during effort. He had felt chest oppression during effort for 1 year,and his chest symptoms had recently worsened. One month before admission he felt chest squeezing at rest in the early morning. He presented at our institution to evaluate his chest symptoms. Electrocardiography and echocardiography failed to show any specific changes. Because of the possibility that his chest symptoms were due to myocardial ischemia,he was admitted to our institution for coronary angiography(CAG). An initial CAG showed mild atherosclerotic changes in the proximal segment of the left anterior descending coronary artery(LAD) and mid-segment of the left circumflex coronary artery. Subsequent spasm provocation testing using acetylcholine revealed a bilateral coronary vasospasm,which was relieved after the intracoronary infusion of nitroglycerin. Finally,a CAG showed myocardial bridging(MB) of the mid-distal segments of the LAD. Fractional flow reserve using the intravenous administration of adenosine triphosphate was positive at 0.77,which jumped up to 0.90 through the myocardial bridging segments when the pressure wire was pulled back. Thus,coronary vasospasm and MB might have contributed to his chest symptoms at rest and during effort. Interventional cardiologists should consider the presence of MB as a potential cause of myocardial ischemia.

    Mentalis muscle responses to electrical stimulation of the zygomatic branch of the facial nerve are considered abnormal muscle responses (AMRs) and can be used to monitor the success of decompression in microvascular decompression (MVD) surgery. The aim of this study was to compare the long-term outcome of MVD surgery in which the AMR disappeared to the outcome of surgery in which the AMR persisted. From 2005 to 2009, 131 patients with hemifacial spasm received MVD surgery with intraoperative monitoring of AMR. At 1 week postsurgery, spasms had resolved in 82% of cases in the AMR-disappearance group and 46% of cases in the persistent-AMR group, mild spasms were present in 10% of cases in the AMR-disappearance group and 31% of cases in the persistent-AMR group, and moderate were present spasms in 8% of cases in the AMR-disappearance group and 23% of cases in the persistent-AMR group (P spasms had resolved in 92% of cases in the AMR-disappearance group and 84% of cases in the persistent-AMR group, mild spasms were present in 6% of cases in the AMR-disappearance group and 8% of cases in the persistent-AMR group, and moderate spasms were present in 3% of cases in the AMR-disappearance group and 8% of the cases in the persistent-AMR group (P = 0.56). These results indicate that the long-term outcome of MVD surgery in which the AMR persisted was no different to that of MVD surgery in which the AMR disappeared.

    Complications of bronchial artery embolization (BAE) are uncommon. A 37-year-old patient with pulmonary tuberculosis received bronchial artery embolization because of severe hemoptysis. The bilateral bronchial arteries and left internal mammary artery were embolized using a gelatin sponge, and the patient exhibited occipital blindness and ataxia after the second BAE. The dissolvable gelatin sponge possibly entered the posterior circulation, resulting in the multiple infarctions in the bilateral occipital lobes and cerebellum. Because of the bad prognosis and the difficulty for curability, this kind of complication should be recognized in a timely manner and carefully avoided by the interventional radiologists carrying out the BAE.

    Full Text Available The aim of the present study was to find out efficacy of cognitive behavior therapy, as an adjunct to standard pharmacotherapy, in bronchial asthma. In a random-ized two-group design with pre-and post assessments, forty asthma patients were randomly allotted to two groups: self management group and cognitive behavior therapy group. Both groups were exposed to 6-8 weeks of intervention, asthma self management program and cognitive behavior therapy. Assessment measures used were-Semi structured interview schedule, Asthma Symptom Checklist, Asthma di-ary, Asthma Bother Profile, Hospital Anxiety & Depression Scale, AQLQ and Peak Expiratory Flow Rate. Within group comparison showed significant improvement in both groups at the post assessment. Between group comparisons showed that CBT group reported significantly greater change than that of SM group. Cognitive behavior therapy helps in improving the managment of asthma.

  9. Bronchial hypersecretion, chronic airflow limitation, and peptic ulcer.

    Men with and men without a history of peptic ulcers were compared using respiratory symptoms and spirographic measurements taken from data recorded in an epidemiologic study. Among the 1,049 men examined, 7% reported a history of peptic ulcer. A clear relationship appeared between bronchial hypersecretion and peptic ulcers. It persisted after adjustment for age, smoking habits, social class, and country of origin. Men with ulcers inhaled tobacco smoke more often. Ulcers, smoking, and chronic phlegm were independently related to a lower body build index. It seems that the relationship between smoking and ulcers was greater among men with chronic phlegm, and it is postulated that peptic ulcers and "chronic bronchitis" might be related to a "common secretory disorder." After adjustment for age, men with a history of peptic ulcers had, not a lower FEV1, but a higher vital capacity. A slightly lower FEV1/VC ratio cannot in such cases be considered as an index of chronic airflow limitation.

    Mast cells and basophils are the only cells expressing the tetrameric (alphabetagamma2) structure of the high affinity receptor for IgE (FcepsilonRI) and synthesizing histamine in humans. Human FcepsilonRI+ cells are conventionally considered primary effector cells of bronchial asthma. There is now compelling evidence that these cells differ immunologically, biochemically, and pharmacologically, which suggests that they might play distinct roles in the appearance and fluctuation of the asthma phenotype. Recent data have revealed the complexity of the involvement of human mast cells and basophils in asthma and have shed light on the control of recruitment and activation of these cells in different lung compartments. Preliminary evidence suggests that these cells might not always be detrimental in asthma but, under some circumstances, they might exert a protective effect by modulating certain aspects of innate and acquired immunity and allergic inflammation.

    Full Text Available Introduction: Asthma is a common chronic disease that affects persons of all ages. People with asthma report impact on the physical, psychological and social domains of quality of life. Health-related quality of life (HRQoL measures have been developed to complement traditional health measures such as prevalence, mortality and hospitalization as indicators of the impact of disease. Objective and Study Design: The objective of this study was to assess HRQoL in Bronchial asthma patients and to relate the severity of asthma with their quality of life. About 85 asthma patients were evaluated for HRQoL and their pulmonary function tests values were correlated with HRQoL scores. Results and Conclusion: It was found that asthma patients had poor quality of life. There was greater impairment in quality of life in females, obese and middle age patients indicating that sex, body mass index and age are determinants of HRQoL in asthma patients.

    The authors review efficiency of various programs of kinesi and hydrokinesitherapy of children with atopic bronchial asthma (BA). Efficiency of the treatment was assessed by quality of life using the questionnaire by A. West, D. French "Childhood asthma questionnaire" (adapted for Russia by V. I. Petrov et al). Monitoring of the activity of allergic inflammation of the upper respiratory tracts was performed by examination of the nasal lavage fluid for nitric oxide metabolites, of the lower respiratory tracts--by the metabolites in the condensate of the expired air. It is shown that hydrokinesitherapy raises BA children's quality of life and declines inflammation activity leading to reduction of the number of BA exacerbations and hospitalizations. The above criteria of the treatment efficacy proved sensitive.

    The CT findings in 10 patients with carcinoid tumors of the lung are reported. The tumors were located in the hilar region, in the perihilar region and in the periphery of the lung. Dystelectasis and atelectasis of the lung with poststenotic inflammation were found in 4 patients. Infiltrating tumor growth with lymph node metastases were detected only once. This tumor was not able to be differentiated from other malignant space occupying lesions. There were no reliable CT criteria for bronchial carcinoids. Compared to conventional radiography the CT examination has the following advantages: better demonstration of size and location of the tumor, and the exlusion of infiltrating tumor growth, enlarged lymph nodes and calcified lung nodules.

    Full Text Available Introduction Modern concept of acupuncture is based on the fact there are designated locations on the surface of human body, which are related to integrative systems of an organism by means of sensory nerves, correlating and synchronizing organ functioning, depending on external and internal conditions, by means of nervous and neurohumoral regulation of metabolic and regenerative processes, including also mobilization of immunological, protective and antistress reactions. Apart from standard needle acupuncture, other methods of stimulating acupuncture points are also applied. Due to invention of low power lasers, irradiation laser acupuncture has been introduced into routine medical practice, characterized by painless and aseptic technique and outstanding clinical results. Material and methods The investigation was aimed at defining therapeutic effects of low power laser irradiation by stimulating acupuncture points or local treatment of asthma. A prospective analysis included 50 patients treated at the Institute of Pulmonary Diseases in Sremska Kamenica during 2000, 2001 and 2002. Together with conservative treatment of present disease, these patients were treated with laser stimulation of acupuncture points in duration of ten days. During treatment changes of functional respiratory parameters were recorded. Results were compared with those in the control group. The control group consisted of the same number of patients and differed from the examination group only by not using laser stimulation. Results Patients with bronchial asthma presented with significant improvement (p<0,0005 of all estimated lung function parameters just 30 minutes after laser stimulation. Improvements achieved on the third and the tenth day of treatment were significantly higher (p<0,001 to p<0,00005 in the examination group in comparison with the control group. Further investigation confirmed that improvement of measured lung function parameters was significantly

  15. Evolutional trends in the management of tracheal and bronchial injuries

    Science.gov (United States)

    2017-01-01

    Tracheal and Bronchial injuries are potentially life threatening complications which require urgent diagnosis and therapeutic intervention. They typically occur in association with blunt and penetrating chest trauma although they are increasingly being encountered in patients following endobronchial intervention and percutaneous tracheostomy insertion. Their precise incidence is unknown. Presenting features include dyspnoea, stridor, respiratory and haemodynamic compromise, haemoptysis, surgical emphysema, pneumothorax and persistent significant airleak. There may be other additional injuries to consider in trauma patients with large airway injury. Familiarity with the diagnosis and management of large airway injuries is important for medical teams engaged in emergency medicine, thoracic surgery and medicine, anaesthesia and intensive care. Although early surgical intervention is the mainstay of treatment, endobronchial manoeuvres to seal defects are receiving increasing attention particularly for patients with medical co-morbidities which may contraindicate formal surgery or transfer or where local surgical expertise is not available.

    Full Text Available Shigemi Yoshihara Department of Pediatrics, Dokkyo Medical University, Tochigi, Japan Abstract: Pranlukast hydrate is a potent, selective, orally active, cysteinyl leukotriene antagonist that binds at the type 1 receptor. It is used as a 10% dry syrup to treat asthma and allergic rhinitis in pediatric patients. In a 4-week, dose-finding study, a dose-dependent improvement in lung function was observed in pediatric patients with asthma at an optimal dose of 5.1–10 mg/kg/day. In a comparative, randomized, double-blind, 4-week multicenter trial, pranlukast dry syrup 7 mg/kg/day achieved significantly better final overall improvement (71.4% versus oxatomide 1 mg/kg/day (37.2% in pediatric patients older than one year with asthma. In two 12-week, open-label trials and in a long-term open-label trial of treatment for up to 24 months, pranlukast dry syrup improved asthma control over baseline values. In a prospective post-marketing surveillance study and a long-term follow-up study, the safety and efficacy of pranlukast dry syrup was confirmed in infants younger than one year with bronchial asthma. In a 4-week, open-label trial, pranlukast dry syrup improved overall health-related quality of life and physical and emotional domain scores over baseline in pediatric patients with asthma. In a randomized, multicenter, double-blind, placebo-controlled, two-period crossover trial, pranlukast dry syrup significantly inhibited exercise-induced bronchospasm in children with asthma compared with placebo. In a modified Childhood Asthma Control Test, pranlukast dry syrup was significantly more effective in controlling asthma in patients younger than 4 years with the common cold. These findings show that pranlukast is useful and beneficial for treating pediatric patients with bronchial asthma. Keywords: pranlukast, leukotriene receptor antagonist, pediatric asthma

    Full Text Available The course of chronic obstructive pulmonary disease (COPD is frequently aggravated by exacerbations, and changes in the composition and activity of the microbiome may be implicated in their appearance. The aim of this study was to analyse the composition and the gene content of the microbial community in bronchial secretions of COPD patients in both stability and exacerbation. Taxonomic data were obtained by 16S rRNA gene amplification and pyrosequencing, and metabolic information through shotgun metagenomics, using the Metagenomics RAST server (MG-RAST, and the PICRUSt (Phylogenetic Investigation of Communities by Reconstruction of Unobserved States programme, which predict metagenomes from 16S data. Eight severe COPD patients provided good quality sputum samples, and no significant differences in the relative abundance of any phyla and genera were found between stability and exacerbation. Bacterial biodiversity (Chao1 and Shannon indexes did not show statistical differences and beta-diversity analysis (Bray-Curtis dissimilarity index showed a similar microbial composition in the two clinical situations. Four functional categories showed statistically significant differences with MG-RAST at KEGG level 2: in exacerbation, Cell growth and Death and Transport and Catabolism decreased in abundance [1.6 (0.2-2.3 vs 3.6 (3.3-6.9, p = 0.012; and 1.8 (0-3.3 vs 3.6 (1.8-5.1, p = 0.025 respectively], while Cancer and Carbohydrate Metabolism increased [0.8 (0-1.5 vs 0 (0-0.5, p = 0.043; and 7 (6.4-9 vs 5.9 (6.3-6.1, p = 0.012 respectively]. In conclusion, the bronchial microbiome as a whole is not significantly modified when exacerbation symptoms appear in severe COPD patients, but its functional metabolic capabilities show significant changes in several pathways.

  18. Bronchial thermoplasty: reappraising the evidence (or lack thereof).

    Bronchial thermoplasty (BT) involves the application of radiofrequency energy to visible proximal airways to selectively ablate airway smooth muscle. BT is the first nonpharmacologic interventional therapy approved by the US Food and Drug Administration (FDA) for severe asthma. This approval was based on the results of the pivotal Asthma Intervention Research (AIR)-2 trial, which is the only randomized, double-blind, sham-controlled trial of BT. The primary end point of the AIR-2 trial was improvement in the Asthma Quality of Life Questionnaire (AQLQ). The results of the AIR-2 trial have generated enormous interest, controversy, and confusion regarding the true efficacy of BT for severe asthma. Current marketing of BT highlights its use for patients with "severe" asthma, which is interpreted by most practicing clinicians as meaning oral corticosteroid dependence, frequent exacerbations, or a significantly reduced FEV1 with a poor quality of life. Did the AIR-2 trial include patients with a low FEV1, oral steroid dependence, or frequent exacerbations? Did the trial show efficacy for any of the primary or secondary end points? The FDA approved the device based on the reduction in severe asthma exacerbations. However, were the rates of asthma exacerbations, ED visits, or hospitalizations truly different between the two groups, and was this type of analysis even justified given the original study design? This commentary is designed to specifically answer these questions and help the practicing clinician navigate the thermoplasty literature with confidence and clarity. We carefully dissect the design, conduct, and results of the AIR-2 trial and raise serious questions about the efficacy of bronchial thermoplasty.

    Full Text Available Abstract. We propose a protocol of treatment in cases of bronchial asthma with cytomegalovirus (CMV persistence. This basic therapy is administered depending on the disease severity, according to the National Programme 2009. The treatment includes administration of human immunoglobulin, with dosage according on CMV antibodies titers. The study has revealed that such regimen of antibody administration based on the content of anti-CMV antibodies in bronchial asthma treatment stops active CMV replication in bronchial mucous membrane, alleviates clinical course of the disease, diminishes changes of immune system typical to children suffering from bronchial asthma and CMV reactivation, thus allowing to reduce the volume of basic therapy, along with maintaining control of asthma control.

    The aim of the study was to evaluate, in a sample of young asthmatics in Italy, the current practice in assessment and treatment of asthma after the publication of guidelines. Young soldiers who declared bronchial asthma at the beginning of the compulsory military service were evaluated. One-hundred and thirty-eight subjects with confirmed asthma were selected. Sixty-seven subjects (48.5%) had had at last one spirometry, and only one subject had underwent peak flow monitoring at home; most of the subjects (96.8%) had had prick tests. More of the 50% of the subjects with bronchial obstruction or with severe bronchial hyperresponsiveness, with clinical moderate or severe asthma, had used only bronchodilators or no therapy at all in the preceding year. In this sample of young asthmatics, the lung function tests were still underutilized for the diagnosis and follow-up of bronchial asthma; moreover, the inhaled anti-inflammatory drugs were still underutilized.

According to the results of clinical examination it was found that in patients with bronchial asthma and obesity of I-II degree efficiency of sanatorium treatment is lower in comparison with patients with bronchial asthma and normal body weight. The use of a standard set of procedures is not enough to correct the symptoms of asthma in obese patients. Comparative analysis of clinical symptoms in patients with bronchial asthma with normal body weight and obesity were differences of up to 50%. The conclusion about the need to develop a set of techniques to optimize the effectiveness of rehabilitation is given.

    Full Text Available Extracorporeal membrane oxygenation (ECMO has been used successfully in critically ill patients with traumatic lung injury and offers an additional treatment modality. ECMO is mainly used as a bridge treatment to delayed surgical management; however, only a few case reports have presented the successful application of ECMO as intraoperative support during the surgical repair of traumatic bronchial injury. A 38-year-old man visited our hospital after a blunt chest trauma. His chest imaging showed hemopneumothorax in the left hemithorax and a finding suspicious for left main bronchus rupture. Bronchoscopy was performed and confirmed a tear in the left main bronchus and a congenital tracheal bronchus. We decided to provide venovenous ECMO support during surgery for bronchial repair. We successfully performed main bronchial repair in this traumatic patient with a congenital tracheal bronchus. We suggest that venovenous ECMO offers a good option for the treatment of bronchial rupture when adequate ventilation is not possible.

    A 77-year-old woman was admitted to the hospital for heart failure with orthopnea. Echocardiography revealed massive mitral regurgitation. During preoperative cardiac catheterization, an aneurysm was indentified incidentally just below the tracheal carina. Three dimensional computed tomography showed three bronchial artery aneurysms behind the pulmonary artery and the left atrium. The proximal aneurysm was the largest and was 22 mm in diameter. It was resected by retracting the ascending aorta to the left, the superior vana cava to the right and right pulmonary artery cranially under cardiopulmonary bypass, and mitral valve plasty was performed. We believed that resection of the proximal aneurysm would cause thrombotic occlusion of the other 2 aneurysms. Bronchial artery aneurysm is a rare entity that is observed in fewer than 1% of those who undergo selective bronchial arteriography. In addition, because bronchial artery aneurysm is a potentially life-threatening lesion, it should be treated promptly when diagnosed.

    We have been performing pre-surgical simulations using custom-built patient-specific 3D-models. Here we report the advantageous use of 3D-models for simulating microvascular decompression(MVD)for hemifacial spasms. Seven cases of MVD surgery were performed. Two types of 3D-printers were used to fabricate the 3D-models:one using plaster as the modeling material(Z Printer®450, 3D systems, Rock Hill, SC, USA)and the other using acrylonitrile butadiene styrene(ABS)(UP! Plus 3D printer®, Beijing Tiertime Technology, Beijing). We tested three types of models. Type 1 was a plaster model of the brainstem, cerebellum, facial nerve, and the artery compressing the root exit zone of the facial nerve. Part of the cerebellum was digitally trimmed off to observe "the compressing point" from the same angle as that used during actual surgery. Type 2 was a modified Type 1 in which part of the skull was opened digitally to mimic a craniectomy. Type 3 was a combined model in which the cerebellum and the artery of the Type 2 model were replaced by a soft retractable cerebellum and an elastic artery. The cerebellum was made from polyurethane and cast from a plaster prototype. To fabricate elastic arteries, liquid silicone was painted onto the surface of an ABS artery and the inner ABS model was dissolved away using solvent. In all cases, the 3D-models were very useful. Although each type has advantages, the Type-3 model was judged extremely useful for training junior surgeons in microsurgical approaches.

    Full Text Available Abstract Background Infantile spasms (IS; West syndrome is a severe form of encephalopathy that typically affects infants younger than 2 years old. Pediatricians, pediatric neurologists, and other pediatric health care providers are all potentially key early contacts for families who have an infant with IS. The objective of this article is to assist pediatric health care providers in the detection of the disease and in the counseling and guidance of families who have an infant with IS. Methods Treatment guidelines, consensus reports, and original research studies are reviewed to provide an update regarding the diagnosis and treatment of infants with IS. Web sites were searched for educational and supportive resource content relevant to providers and families of patients with IS. Results Early detection of IS and pediatrician referral to a pediatric neurologist for further evaluation and initiation of treatment may improve prognosis. Family education and the establishment of a multidisciplinary continuum of care are important components of care for the majority of patients with IS. The focus of the continuum of care varies across diagnosis, initiation of treatment, and short- and long-term needs. Several on-line educational and supportive resources for families and caregivers of patients with IS were identified. Conclusions Given the possibility of poor developmental outcomes in IS, including the emergence of other seizure disorders and cognitive and developmental problems, early recognition, referral, and treatment of IS are important for optimal patient outcomes. Dissemination of and access to educational and supportive resources for families and caregivers across the lifespan of the child with IS is an urgent need.

    Background Angina without significant stenosis, or nonobstructive coronary artery disease, attracts clinical attention. Microvascular coronary artery spasm (microvascular CAS) can cause nonobstructive coronary artery disease. We investigated the clinical features of microvascular CAS and the therapeutic efficacy of calcium channel blockers. Methods and Results Three hundred seventy consecutive, stable patients with suspected angina presenting nonobstructive coronary arteries (<50% diameter) in coronary angiography were investigated with the intracoronary acetylcholine provocation test, with simultaneous measurements of transcardiac lactate production and of changes in the quantitative coronary blood flow. We diagnosed microvascular CAS according to lactate production and a decrease in coronary blood flow without epicardial vasospasm during the acetylcholine provocation test. We prospectively followed up the patients with calcium channel blockers for microvascular coronary artery disease. We identified 50 patients with microvascular CAS who demonstrated significant impairment of the endothelium-dependent vascular response, which was assessed by coronary blood flow during the acetylcholine provocation test. Administration of isosorbide dinitrate normalized the abnormal coronary flow pattern in the patients with microvascular CAS. Multivariate logistic regression analysis indicated that female sex, a lower body mass index, minor–borderline ischemic electrocardiogram findings at rest, limited–baseline diastolic-to-systolic velocity ratio, and attenuated adenosine triphosphate–induced coronary flow reserve were independently correlated with the presence of microvascular CAS. Receiver-operating characteristics curve analysis revealed that the aforementioned 5-variable model showed good correlation with the presence of microvascular CAS (area under the curve: 0.820). No patients with microvascular CAS treated with calcium channel blockers developed cardiovascular

    Full Text Available We previously showed that phospholipase C (PLC-δ1 activity was enhanced by 3-fold in patients with coronary spastic angina (CSA. We also reported that p122Rho GTPase-activating protein/deleted in liver cancer-1 (p122RhoGAP/DLC-1 protein, which was discovered as a PLC-δ1 stimulator, was upregulated in CSA patients. We tested the hypothesis that p122RhoGAP/DLC-1 overexpression causes coronary spasm.We generated transgenic (TG mice with vascular smooth muscle (VSM-specific overexpression of p122RhoGAP/DLC-1. The gene and protein expressions of p122RhoGAP/DLC-1 were markedly increased in the aorta of homozygous TG mice. Stronger staining with anti-p122RhoGAP/DLC-1 in the coronary artery was found in TG than in WT mice. PLC activities in the plasma membrane fraction and the whole cell were enhanced by 1.43 and 2.38 times, respectively, in cultured aortic vascular smooth muscle cells from homozygous TG compared with those from WT mice. Immediately after ergometrine injection, ST-segment elevation was observed in 1 of 7 WT (14%, 6 of 7 heterozygous TG (84%, and 7 of 7 homozygous TG mice (100% (p<0.05, WT versus TGs. In the isolated Langendorff hearts, coronary perfusion pressure was increased after ergometrine in TG, but not in WT mice, despite of the similar response to prostaglandin F2α between TG and WT mice (n = 5. Focal narrowing of the coronary artery after ergometrine was documented only in TG mice.VSM-specific overexpression of p122RhoGAP/DLC-1 enhanced coronary vasomotility after ergometrine injection in mice, which is relevant to human CSA.

    Background. To date, bronchial diverticula have generally been treated as a pathological condition associated with chronic obstructive pulmonary disease (COPD), although only a limited amount of published information is available on the relationship between bronchial diverticula as depicted by multidetector computed tomography (MDCT) and airflow limitations. Purpose. To evaluate the relationship between airflow limitations and main bronchial diverticula in the subcarinal region using spirometry and thin-section MDCT. Material and Methods. A total of 189 consecutive adult patients were retrospectively evaluated based on spirometry and thin-section MDCT of the chest. All examinations were performed at our institution between June and October 2008. The study group included 70 women and 119 men with a mean age of 65 years (range 19-86 years). The relationship between the FEV1% and bronchial diverticula in the subcarinal region was analyzed (Student's t-test). Results. The indications for conducting the examinations were pulmonary diseases (82 patients), cardiovascular diseases (22), extrapulmonary malignancies (74), and other conditions (11). A total of 84/189 (44.4%) patients showed bronchial diverticula, and the FEV{sub 1}% of 70/84 (83.3%) patients was above 70. The FEV{sub 1}% of patients with lesions ranged from 26.0 to 97.8 (mean 76.8), whereas the range was 28.1-94.4 (mean 73.7) in those without lesions. There was no significant association between the FEV{sub 1}% and the presence of subcarinal bronchial diverticula (P > 0.05). Conclusion. Our data demonstrate that thin-section chest CT commonly demonstrates main bronchial diverticula in the subcarinal region in patients without airflow limitations. We propose that the presence of a small number of tiny bronchial diverticula under the carina may not be a criterion for the diagnosis of COPD

    Conclusion: According to our study, it could be concluded that l-carnitine decrease is linked to the occurrence of attack of bronchial asthma. Accordingly, it is recommended to make further studies to find out if there is a beneficial role of carnitine intake in the prophylaxis & treatment of attacks of bronchial asthma. The recommended studies should search for the most suitable dose & side effects of carnitine as a potential pharmaceutical agent.

    Full Text Available Churg-Strauss syndrome (CSS is a rare cause of vasculitic neuropathy. Although rare and potentially fatal, Churg-Strauss syndrome (CSS is easily diagnosable and treatable. The presence of bronchial asthma with peripheral neuropathy in a patient alerts a physician to this diagnosis. This is vividly illustrated by the presented two cases who had neuropathy associated with bronchial asthma, eosinophilia, sinusitis, and positive perinuclear antineutrophil cytoplasmic antibodies (p-ANCA test, which improved with administration of steroids.

    Full Text Available BACKGROUND: Our quantitative proteomic study showed that selenium-binding protein 1 (SELENBP1 was progressively decreased in human bronchial epithelial carcinogenic process. However, there is little information on expression and function of SELENBP1 during human lung squamous cell cancer (LSCC carcinogenesis. METHODS: iTRAQ-tagging combined with 2D LC-MS/MS analysis was used to identify differentially expressed proteins in the human bronchial epithelial carcinogenic process. SELENBP1, member of selenoproteins family and progressively downregulated in this process, was selected to further study. Both Western blotting and immunohistochemistry were performed to detect SELENBP1 expression in independent sets of tissues of bronchial epithelial carcinogenesis, and ability of SELENBP1 for discriminating NBE (normal bronchial epithelium from preneoplastic lesions from invasive LSCC was evaluated. The effects of SELENBP1 downregulation on the susceptibility of benzo(apyrene (B[a]P-induced human bronchial epithelial cell transformation were determined. RESULTS: 102 differentially expressed proteins were identified by quantitative proteomics, and SELENBP1 was found and confirmed being progressively decreased in the human bronchial epithelial carcinogenic process. The sensitivity and specificity of SELENBP1 were 80% and 79% in discriminating NBE from preneoplastic lesions, 79% and 82% in discriminating NBE from invasive LSCC, and 77% and 71% in discriminating preneoplastic lesions from invasive LSCC, respectively. Furthermore, knockdown of SELENBP1 in immortalized human bronchial epithelial cell line 16HBE cells significantly increased the efficiency of B[a]P-induced cell transformation. CONCLUSIONS: The present data shows for the first time that decreased SELENBP1 is an early event in LSCC, increases B[a]P-induced human bronchial epithelial cell transformation, and might serve as a novel potential biomarker for early detection of LSCC.

    AIM: To investigate the effect ofchymase on the mucin secretion from human bronchial epithelial cells. METHODS:Primarily-cultured human bronchial epithelial (PCHBE) cells and normal human bronchial epithelial (NHBE) cells were cultured with chymase or other stimulus in a mixture of bronchial epithelial growth medium (BEGM) and Dulbecco's modified Eagle's medium (DMEM), and the quantities of stimulatory mucin release were recorded.MUC5AC mucin was measured with an ELISA and dolichos biflorus agglutinin (DBA) mucin was determined with an enzyme linked DBA assay. RESULTS: A dose-dependent secretion of DBA mucin from PCHBE cells was observed with chymase with a maximum secretion of 98 % above baseline being achieved following 3 h incubation.The action of chymase started from 1 h, peaked at 3 h and dramatically decreased at 20 h following incubation.Chymase was able to also stimulate approximately 38 % increase in MUC5AC mucin release from PCHBE cells, and about 121% increase in DBA mucin release from NHBE cells. A chymase inhibitor soybean trypsin inhibitor (SBTI)was able to inhibit up to 85 % chymase induced mucin release, indicating that the enzymatic activity was essential for the actions of chymase on bronchial epithelial cells. CONCLUSION: Chymase is a potent stimulus of mucin secretion from human bronchial epithelial cells. It can contribute to mucus hypersecretion process in the patients with chronic obstructive pulmonary disease or asthma.

    Bronchial asthma is a worldwide disease with high incidence. It not only harms children's physical and mental health, but it also brings a heavy burden to their families as well as the society. However, the trigger and pathogenesis of the disease remain unclear. This study aimed to analyze TRPV1 gene mutation and expression of cytokines in children with acute bronchial asthma before and after treatment, thus providing theoretical guidance for the diagnosis and treatment of bronchial asthma in children. Real-time quantitative polymerase chain reaction was adopted to detect TRPV1 mRNA expression level and enzyme-linked immuno sorbent assay was used to detect the serum total IgE level, eosinophil (EOS) number, IL-4, IL-5, and interferon (IFN) gamma levels in peripheral venous blood of children in the healthy control group and asthma group before and after treatment. Logistic regression analysis was applied to analyze the most essential factor inducing bronchial asthma in children. TRPV1 mRNA level of peripheral blood in the asthma group was higher than that in the control group before treatment (p asthma in children. TRPV1 gene mutation was closely related to bronchial asthma in children, which provided a theoretical basis for the treatment and prognosis of children with bronchial asthma.

    Background It is not uncommon that only mild coronary artery stenosis is grossly revealed after a system autopsy. While coronary artery spasm (CAS) is the suspected mechanism of these deaths, no specific biomarker has been identified to suggest antemortem CAS. Material/Methods To evaluate the potential of using phosphorylated myosin light chain 2 (p-MLC2) as a diagnostic marker of antemortem CAS, human vascular smooth muscle cells (VSMCs) were cultured and treated with common vasoconstrictors, including prostaglandins F2α (PGF2α), acetylcholine (ACh), and 5-hydroxy tryptamine (5-HT). The p-MLC2 level was examined in the cultured cells using Western blot analysis and in a rat model of spasm provocation tests using immunohistochemistry (IHC). Effects of increased p-MLC2 level on VSMCs contractile activities were assessed in vitro using confocal immunofluorescence assay. Four fatal cases with known antemortem CAS were collected and subject to p-MLC2 detection. Results The p-MLC2 was significantly increased in VSMCs after treatments with vasoconstrictors and in the spasm provocation tests. Myofilament was well-organized and densely stained in VSMCs with high p-MLC2 level, but disarrayed in VSMCs with low p-MLC2 level. Three of the 4 autopsied cases showed strongly positive staining of p-MLC2 at the stenosed coronary segment and the adjacent interstitial small arteries. The fourth case was autopsied at the 6th day after death and showed negative-to-mild positive staining of p-MLC2. Conclusions p-MLC2 might be a useful marker for diagnosis of antemortem CAS. Autopsy should be performed as soon as possible to collect coronary arteries for detection of p-MLC2. PMID:27643564

    Systemic involvement is well known in patients with inflammatory bowel diseases (IBD), but there are only few data looking to Crohn’s disease (CD) and ulcerative colitis (UC) separately instead of lumping together both entities to IBD. The frequency of bronchial involvement in UC is not yet exactly analysed but reported to be rare. We asked 100 patients with UC for bronchial complaints, and found in 13 patients a bronchial affection. From reports in the literature it is known that sometimes a bronchial involvement in patients with UC can affect the whole bronchial tree including small bronchi. The involvement of bronchial system in UC is obviously more prominent than previously thought and may fulfil the criteria for a separate syndrome. These relations may have consequences for pathogenetic understanding of UC as well as bronchitis and also consequences for treatment regimes. PMID:25834480

    Full Text Available We examined the effect of the immunosuppressive agent, tacrolimus (FK506, on antigen-induced bronchial hyperreactivity to acetylcholine and leukocyte infiltration into the airways of ovalbumin-challenged guinea-pigs. Subcutaneous injection of 0.5 mg/kg of FK506, 1 h before and 5 h after intra-nasal antigen challenge prevented bronchial hyperreactivity to aerosolized acetylcholine, eosinophilia in bronchoalveolar lavage (BAL fluid and bronchial tissue and the invasion of the bronchial wall by CD4+ T-lymphocytes. FK506 also suppressed ovalbumininduced increase in the number of leukocytes adhering to the pulmonary vascular endothelium and expressing α4-integrins. Inhibition by FK506 of antigen-induced bronchial hyperreactivity in sensitized guinea-pigs may thus relate to its ability to prevent the emergence of important inflammatory components of airway inflammation, such as eosinophil accumulation, as well as CD4+ T-lymphocyte infiltration into the bronchial tissue.

    2015-10-01

    Bell palsy occurs in different rheumatic diseases, causes hemifacial weakness, and targets the motor branch of the 7th cranial nerve. Severe, persistent, and refractory otalgia having features of neuropathic pain (ie, burning and allodynic) does not characteristically occur with Bell palsy. Whereas aberrant regeneration of the 7th cranial nerve occurring after a Bell palsy may lead to a variety of clinical findings, hemifacial spasm only rarely occurs. We identified in 3 rheumatic disease patients (2 with Sjögren syndrome, 1 with rheumatoid arthritis) a previously unreported neurological syndrome of facial weakness, otalgia with neuropathic pain features, and hemifacial spasm. We characterized symptoms, examination findings, and response to therapy. All 3 patients experienced vertigo, as well as severe otalgia which persisted after mild facial weakness had completely resolved within 1 to 4 weeks. The allodynic nature of otalgia was striking. Two patients were rendered homebound, as even the barest graze of outdoor breezes caused intolerable ear pain. Patients developed hemifacial spasm either at the time of or within 3 months of facial weakness. Two patients had a polyphasic course, with recurrent episodes of facial weakness and increased otalgia. In all cases, otalgia and hemifacial spasm were unresponsive to neuropathic pain regimens, but responded in 1 case to intravenous immunoglobulin therapy. No patients had vesicles or varicella zoster virus in spinal-fluid studies. We have defined a novel neurological syndrome in 3 rheumatic disease patients, characterized by facial weakness, otalgia, and hemifacial spasm. As described in infectious disorders, the combination of otalgia, facial weakness, and 8th cranial nerve deficits suggests damage to the geniculate ganglia (ie, the sensory ganglia of the 7th cranial nerve), with contiguous involvement of other cranial nerves causing facial weakness and vertigo. However, the relapsing nature and association with

    Objective. To introduce the properties of Chinese type A botulinum toxin (CBTXA, made by Lanzhou Institute of Biological Products), and its long-term effect for focal dystonia and hemifacial spasm. Method. The purity and recovery of crude and crystalline toxin were tested. Long-term data from 305 patients with hemifacial spasm (HFS), blepharospasm (BS) and cervical dystonia (CD) were evaluated and subgroups of patients received CBTXA injections between 1994 and 2000 in at least six separate treatment sessions, with follow up for 2-8 years. The therapeutic results of the last session CBTXA injections were analyzed in comparison with the first session. Result. CBTXA purity was high[(2.55~2.60)×107D50/mgPr, A260/A280 ≤0.55, high molecular substance accounted for 99.2% of total proteins]. Long term treatment with CBTXA in patients with focal dystonia and HFS was not associated with any decline in benefit, and efficacy may improve slightly with repeat treatments. CBTXA is an excellent long-term treatment of HFS, BS and CD. Conchusion. We conclude that Chinese type A botulinum toxin is of botulinum toxin therapy quality standard according to results obtained from the basic study and long-term clinical applications. The reinjection of CBTXA significantly improves the quality of life of most patients and is a safe, effective and comparatively economical treatment for patients with focal dystonia and HFS.

    We report a 70-year-old man, who developed painful involuntary muscle contraction of the left leg after the lumbar discectomy, which exacerbated after a vertebral fracture of Th12. This involuntary movement was accompanied with the abnormal position of left leg simulating triple flexion response, and was induced by active or passive movement of his left knee and foot joints. Several drugs including benzodiazepines and dantrolene were ineffective, although treatment with baclofen or carbamazepine was effective. These findings suggest that hyperexcitability of the anterior horn cells following the disturbance of spinal inhibitory interneurons was involved. Electophysiological studies suggested the disturbance of left lumber nerve roots. The spinal root blocks from L3 to S1 were performed, after which the painful involuntary muscle spasm was resolved. The lumbar sympathetic ganglia block was also effective; suggesting that abnormal afferent neuronal input to spinal cord was caused by the nerve root trauma which triggered the formation of secondary abnormal network in the spine. Lumbar sympathetic ganglia block should be recommended to a therapeutic option for the refractory painful muscle spasm of the leg.

    Previous studies of epileptic spasms reported that ictal events were associated with high-frequency oscillations (HFOs) or delta waves involving widespread regions. We determined whether ictal HFOs at 80-200 Hz were coupled with a phase of slow-wave, whether ictal slow-waves were diffusely or locally synchronous signals, and whether the mode of coupling between HFOs and slow-wave phases differed between ictal and interictal states. We studied 11 children who underwent extraoperative electrocorticography (ECoG) recording. The phases and amplitudes of slow-waves were measured at the peak of ictal and interictal HFOs in the seizure-onset sites. Ictal HFOs were locked tightly to the phase of slow-wave at ≤1 Hz. Ictal slow-waves propagated from the seizure-onset site to other regions. In contrast, interictal HFOs in the seizure-onset site were loosely locked to the phase of slow-wave at ≤1 Hz but tightly to that of ≥3-Hz. Ictal slow-waves coupled with HFOs can be explained as near-field and locally synchronized potentials generated by the neocortex rather than far-field potentials generated by subcortical structures. Ictal slow-waves in epileptic spasms may be generated by a mechanism different from what generates interictal HFOs-slow-wave complexes.

    Full Text Available In comparison of effects of various drugs with the same indications produced by different companies or comparing drugs manufactured in Iran with their foreign counterparts may result in producing drugs with higher qualities in our country. In this study the spasmolithic effect of two herbal drugs , gripe mixture and caraway mixture , that are prescribed as spasmolithic and carminative in infants were compared. 2 cm of rat jejunum was placed in a organ bath containing tyrode solution (37 C , 100% O2 . The jejunum was contracted because of acetylcholine (1 ml. when the muscle contraction reached the plateau the different volumes of drug were added to the organ bath. The inhibitory effect of drug indicated by physiograph , the intestine was washed two times. When the intestine reached the basal tonicity , the different volumes of second drug were tested. The results were compared using paired t.test The results show that both drugs inhibit the spasm induced by acetylcholine in rat jejunum . This inhibitory effect was dose dependent. The caraway mixture showed a higher effect in comparison with gripe mixture (P<0.05. The caraway mixture has a higher inhibitory effect on acetylcholine induced spasm in rat jejunum . It seems that it has the same effect on human.

    Our previous studies demonstrated that the abnormal muscle response could vanish when the ipsilateral superior cervical ganglion was removed and reappear when norepinephrine was dripped at the neurovascular conflict site. Evidentially, we believed that the mechanism of hemifacial spasm should involve emersion of ectopical action potential in the compressed facial nerve fibers. As the action potential is ignited by ion channel opening, we focused on Nav1.8 that has been found overexpressed in peripheral nerve while damaged. In this study, Moller model was adopted, 20 Sprague-Dawley rats underwent drip of norepinephrine, and the abnormal muscle response wave was monitored in 14 rats. Antibodies against unique epitopes of the α subunit of sodium channel isoforms were used to detect the Nav1.8 neuronal isoforms, and the immunohistochemistry showed strong staining in 13 rats, which were all in the abnormal muscle response positive group (P spasm is an ectopic action potential that emerged on the damaged facial nerve, which might be coupled by Nav1.8.

    Full Text Available Tetanus toxin, the product of Clostridium tetani, is the cause of tetanus symptoms. Tetanus toxin is taken up into terminals of lower motor neurons and transported axonally to the spinal cord and/or brainstem. Here the toxin moves trans-synaptically into inhibitory nerve terminals, where vesicular release of inhibitory neurotransmitters becomes blocked, leading to disinhibition of lower motor neurons. Muscle rigidity and spasms ensue, often manifesting as trismus/lockjaw, dysphagia, opistotonus, or rigidity and spasms of respiratory, laryngeal, and abdominal muscles, which may cause respiratory failure. Botulinum toxin, in contrast, largely remains in lower motor neuron terminals, inhibiting acetylcholine release and muscle activity. Therefore, botulinum toxin may reduce tetanus symptoms. Trismus may be treated with botulinum toxin injections into the masseter and temporalis muscles. This should probably be done early in the course of tetanus to reduce the risk of pulmonary aspiration, involuntary tongue biting, anorexia and dental caries. Other muscle groups are also amenable to botulinum toxin treatment. Six tetanus patients have been successfully treated with botulinum toxin A. This review discusses the use of botulinum toxin for tetanus in the context of the pathophysiology, symptomatology, and medical treatment of Clostridium tetani infection.

Lung function parameters and comorbidities of the patient, as well as the extent and distribution of the emphysema are factors to be considered when choosing the patient and the intervention. Endoscopic bronchial valve placement with complete occlusion of one lobe in patients with heterogeneous emphysema is the preferred technique because of its reversibility. The presence of high interlobar collateral ventilation will hinder successful treatment; therefore, endoscopic coil placement, polymeric lung volume reduction, or bronchoscopic thermal vapor ablation as well as lung volume reduction surgery can be used for treating patients with incomplete fissures. The effect of endoscopic lung volume reduction in patients with a homogeneous distribution of emphysema is still unclear and this subgroup should be treated only in clinical trials. Precise patient selection is necessary for interventions and to improve the outcome and reduce the risk and possible complications. Therefore, the patients should be discussed in a multidisciplinary approach prior to determining the most appropriate treatment for lung volume reduction.

    Metals such as arsenic, cadmium, beryllium, and nickel are known human carcinogens; however, other transition metals, such as tungsten (W), remain relatively uninvestigated with regard to their potential carcinogenic activity. Tungsten production for industrial and military applications has almost doubled over the past decade and continues to increase. Here, for the first time, we demonstrate tungsten’s ability to induce carcinogenic related endpoints including cell transformation, increased migration, xenograft growth in nude mice, and the activation of multiple cancer related pathways in transformed clones as determined by RNA seq. Human bronchial epithelial cell line (Beas-2B) exposed to tungsten developed carcinogenic properties. In a soft agar assay, tungsten-treated cells formed more colonies than controls and the tungsten-transformed clones formed tumors in nude mice. RNA-sequencing data revealed that the tungsten-transformed clones altered the expression of many cancer-associated genes when compared to control clones. Genes involved in lung cancer, leukemia, and general cancer genes were deregulated by tungsten. Taken together, our data shows the carcinogenic potential of tungsten. Further tests are needed, including in vivo and human studies, in order to validate tungsten as a carcinogen to humans. PMID:26164860

    New Mexico was the largest producer of uranium in the western world during 1960s and 1970s. Investigators at the University of New Mexico School of Medicine`s Epidemiology and Cancer Control Program have been conducting epidemiological studies on uranium miners over the past 2 decades. Currently, this cohort includes more than 3600 men who had completed at least 1 y of underground work experience in New Mexico by December 31, 1976. These miners, who are now in their 5th through 7th decades, the age when lung cancer incidence is highest, are at high risk for developing this disease because they were exposed to high levels of radon progeny in the mines, and they also smoked tobacco. However, not all people comparably exposed develop lung cancer; in fact, the lifetime risk of lung cancer for the smoking uranium miners has been projected by epidemiological analyses to be no higher than 50%. Therefore, the identification of gene alterations in bronchial epithelium would be a valuable tool to ascertain which miners are at greatest risk for lung cancer. The underlying significance of the current effort confirms the hypothesis that chronic exposure to high concentrations of {alpha}-particles and tobacco smoke produces genetically altered lung epithelial cells throughout the respiratory tract of some susceptible individuals before they develop clinical disease.

    Chronic exposure to asbestos fibers results in fibrotic lung disease. The distal pulmonary epithelium is an early target of asbestos-mediated injury. Local plasmin activity may be important in modulating endoluminal inflammatory responses in the lung. We studied the effects of asbestos exposure on cell-mediated plasma clot lysis as a marker of pericellular plasminogen activation. Exposing human bronchial epithelial (HBE) cells to 100 micrograms/ml of asbestos fibers for 24 h resulted in increased plasma clot lysis. Fibrinolytic activity was augmented in a dose-dependent fashion, was not due to secreted protease, and occurred only when there was direct contact between the plasma clot and the epithelial monolayer. Further analysis showed that asbestos exposure increased HBE cell-associated urokinase-type plasminogen activator (uPA) activity in a time-dependent manner. The increased cell-associated PA activity could be removed by acid washing. The increase in PA activity following asbestos exposure required new protein synthesis because it was abrogated by treatment with either cycloheximide or actinomycin D. Therefore, asbestos exposure increases epithelial-mediated fibrinolysis by augmenting expression of uPA activity at the cell surface by mechanisms that require new RNA and protein synthesis. These observations suggest a novel mechanism whereby exposure of the distal epithelium to inhaled particulates may result in a chronic inflammatory response that culminates in the development of fibrotic lung disease.

    The effect of 4% lidocaine inhalation was studied in a single-blind fashion in 18 patients with chronic stable asthma. Inhalation of normal saline solution was used as placebo. None of the parameters except flow rate at 50% of vital capacity (V50) showed any statistically significant change from baseline values. V50 at 15 min was significantly lower (p less than 0.05) after 4% lidocaine inhalation. Considering more than 10% change from the baseline value as significant, 8 of 15 patients showed decrease in airway resistance (Raw) and 7 of the 15 patients showed an increase in specific airway conductance (SGaw) after 15 min of inhalation. However, V50 (8/18 patients), flow rate at 25% vital capacity [V25 (6/15 patients], and forced expiratory flow rate at 25-75% of the vital capacity (FEF25-75) (5/15 patients) showed a decrease after 15 min of 4% lidocaine inhalation. No change in pulmonary function was noted after 30 min of lidocaine inhalation. It is concluded from this study that lidocaine produces a small bronchodilatory effect on the large airways and a bronchoconstrictor effect on the small airways after 15 min of inhalation, but this effect is not statistically significant. It can be safely used as topical agent for bronchoscopy in patients with bronchial asthma.

    To find the rebleeding factors in bronchial arterial embolization for treatment of hemoptysis, a retrospective study was performed. Medical records, angiographic findings and embolic materials of 35 patients who had undertaken arterial embolization for control of hemoptysis were reviewed. The period of follow-up for rebleeding was from 3 to 32 months after arterial embolization. We investigated the angiographic findings of extravasation, neovascularity, intervascular shunt, aneurysm and periarterial diffusion. Neovascularity was classified as mild(numerable neovascularity) and severe(innumerable). Rebleeding occurred in 15(43%) among 35 cases. Only two of 11 cases with no past episode of hemoptysis showed recurrence, while 9 of 15 cases who had more than three episodes did. Severe neovascularity were seen in 11 of 15 recurred cases, but seven of 20 non- recurred cases showed severe neovascularity. More than three angiographic findings representing hemoptysis were seen on 11(73%) among recurred 15 cases and seven(35%) among non- recurred 20 cases. The lesion was supplied by more than two different arteries on 8(54%) of the recurred cases, but only three(15%) of the non- recurred cases. Six of seven cases persistent neovascularity after arterial embolization were recurred. The history of repeated hemoptysis, severe neovascularity, variable angiographic findings, and post-embolization persistency of neovascularity were the factors related with the rebleeding after arterial embolization for hemoptysis. Careful and active arterial embolization are required on these conditions.

    Approximately 5% of the ~3 million asthmatics in South Africa have severe asthma that is associated with substantial morbidity, cost, absenteeism, preventable mortality, and the requirement for costly chronic medication that may be associated with significant adverse events. There is an unmet need for alternative safer and more effective interventions for severe asthma. A recently introduced option, bronchial thermoplasty (BT), imparts radiofrequency-generated heat energy to the airways to cause regression of airway smooth muscle. The effectiveness of this technique has been confirmed in randomised control trials and is now endorsed by several international guidelines, including the Global Initiative for Asthma (GINA) guideline, the British Asthma Guideline, and the UK National Institute of Clinical Excellence (NICE) guideline. We recommend BT as a potential therapeutic intervention for severe uncontrolled asthma, provided that it is performed by an experienced pulmonologist at an accredited centre and done within the broader context of appropriate management of the disease by doctors experienced in treating difficult-to-control asthma.

The present article in particular focuses on the relaxation exercises, made up of Progressive Muscle Relaxation and Autogenic Training elements as well as of phantasy travels, mantras, and periodic music. Ongoing observation of the children during training, the findings of subsequent semi-structured interviews with them, topical instances of coping with impending asthma attacks by using the techniques learned, as well as the results of a catamnestic inquiry some three years later--all indicate a positive impact of the relaxation exercises. Statistical analysis of the data at hand revealed significant improvements in a number of pulmonary function parameters (airway resistance, forced expiratory volume for 1 s, forced vital capacity, peak expiratory flow rate). Interpretation of these findings must however take into account the entirety of the training provided.

    Well-differentiated bronchial neuroendocrine tumors (B-NETs) are rare. They represent 1-5 % of all lung cancers. The incidence of these neoplasms has risen over the past 30 years and, especially for advanced or metastatic disease, management is complex and requires a multidisciplinary approach. Treatment with somatostatin analogs (SSAs) is the most important first-line therapy, in particular in well-differentiated NETs with high somatostatin type receptor (SSTR) expression. In these tumors, the role of mammalian target of rapamycin (m-TOR) inhibitors and the potential utility of other target therapies remain unclear while chemotherapy represents the gold standard treatment only for aggressive forms with low SSTR expression. Peptide receptor radionuclide therapy (PRRT) is an emerging treatment modality for advanced NETs. There are many cumulative evidences about the effectiveness and tolerability of this therapeutic approach, especially in gastro-entero-pancreatic (GEP)-NETs. For B-NETs, scientific research is moving more slowly. Here, we performed a review in order to evaluate the efficacy and toxicity of PRRT with a focus on patients with inoperable or metastatic well-differentiated B-NETs.

    Bronchial hyperresponsiveness (BHR) is one of the hallmarks of asthma. BHR correlates well with asthmatic symptoms and the response to treatment. Moreover, BHR appears to be closely related to airways inflammation. Numerous studies have demonstrated a familial aggregation; however, this phenotype is not likely inherited as a simple Mendelian trait. BHR is also closely associated with total serum IgE levels, as are allergy and asthma. We studied 92 families from Northern Holland ascertained through a parent with asthma who were originally studied between 1962-1970. Since there are a number of candidate genes on chromosome 5q potentially important in producing BHR, families were genotyped for markers in this region. These genes regulate IgE production and the cellular elements that are likely involved in inflammation associated with BHR, allergy and asthma. They include IL-4, IL-3, IL-5, IL-9, IL-12, IL-13 and GM-CSF. Linkage of BHR with markers on 5q was tested using a model free sib-pair method. The data suggest a locus for BHR maps near the cytokine gene cluster on 5q. This region appears critical in producing susceptibility to BHR and possibly to asthma.

    Full Text Available INTRODUCTION: Intestinal or hepatic ischemia/reperfusion induces acute lung injury in animal models of multiple organ failure. Tumor necrosis factor (TNF- alpha is involved in the underlying inflammatory mechanism of acute respiratory distress syndrome. Although the inflammatory cascade leading to acute respiratory distress syndrome has been extensively investigated, the mechanical components of acute respiratory distress syndrome are not fully understood. Our hypothesis is that splanchnic ischemia/reperfusion increases airway reactivity and serum TNF-alpha levels. OBJECTIVE: To assess bronchial smooth muscle reactivity under methacholine stimulation, and to measure serum TNF-alpha levels following intestinal and/or hepatic ischemia/reperfusion in rats. METHOD: Rats were subjected to 45 minutes of intestinal ischemia, or 20 minutes of hepatic ischemia, or to both (double ischemia, or sham procedures (control, followed by 120 minutes of reperfusion. The animals were then sacrificed, and the bronchial response to increasing methacholine molar concentrations (10-7 to 3 x 10-4 was evaluated in an ex-vivo bronchial muscle preparation. Serum TNF-alpha was determined by the L929-cell bioassay. RESULTS: Bronchial response (g/100 mg tissue showed increased reactivity to increasing methacholine concentrations in the intestinal ischemia and double ischemia groups, but not in the hepatic ischemia group. Similarly, serum TNF-alpha (pg/mL concentration was increased in the intestinal ischemia and double ischemia groups, but not in the hepatic ischemia group. CONCLUSION: Intestinal ischemia, either isolated or associated with hepatic ischemia, increased bronchial smooth muscle reactivity, suggesting a possible role for bronchial constriction in respiratory dysfunction following splanchnic ischemia/reperfusion. This increase occurred in concomitance with serum TNF-alpha increase, but whether the increase in TNF-alpha caused this bronchial contractility remains

    Background Pepsin plays a role in gastroesophageal reflux (GER). Aims of this study were to verify if pepsin could be the cause of frequent bronchial exacerbations and to check if the persistence of chronic respiratory symptoms were correlated with pre-existing respiratory diseases. Methods From January to May 2016, 42 patients underwent a diagnostic bronchoscopy. All patients had a history of at least one bronchial exacerbation during the previous year. Bronchial lavage fluid specimens were obtained. A semiquantitative assessment of pepsin in the samples was carried out based on the intensity of the test sample. Results Pepsin was present in 37 patients (88%), but in patients with bronchial asthma and chronic obstructive pulmonary disease (COPD), the finding of pepsin in the bronchoalveolar fluid was 100%. There was a strong positive statistical correlation between pepsin detection and radiological signs of GER (ρ=0.662), and between pepsin detection and diagnosis (ρ=0.682). No correlation was found between the bacteriology and the presence of pepsin in the airways (ρ=0.006). Conclusions The presence of pepsin in the airways shows the occurrence of reflux. The persistence of respiratory symptoms by at least 2 months suggest an endoscopic bronchial examination. This straightforward test confirms the cause possible irritation of the airways and may prevent further diagnostic tests, such as an EGD or pH monitoring esophageal. PMID:27668224

    Angiotensin converting enzyme (ACE) inhibitors therapy is aassociated with bothersome dry cough as an adverse effect. The mechanisms underlying this adverse effect are not clear. Therefore, influence of captopril (an ACE inhibitor) on acetylcholine (ACh)-induced bronchial smooth muscle contractions was investigated. Further, the mechanisms underlying the captopril-induced changes were also explored. In vitro contractions of rat bronchial smooth muscle to cumulative concentrations of ACh were recorded before and after exposure to captopril. Further, the involvement of kinin and inositol triphosphate (IP₃) pathways for captopril-induced alterations were explored. ACh produced concentration-dependent (5-500 µM) increase in bronchial smooth muscle contractions. Pre-treatment with captopril augmented the ACh-induced contractions at each concentration significantly. Pre-treatment with aprotinin (kinin synthesis inhibitor) or heparin (inositol triphosphate, IP₃-inhibitor), blocked the captopril-induced augmentation of bronchial smooth muscle contractions evoked by ACh. Further, captopril-induced augmentation was absent in calcium-free medium. These results suggest that captopril sensitizes bronchial smooth muscles to ACh-induced contractions. This sensitization may be responsible for dry cough associated with captopril therapy.

    We reported the case of a36 years old woman involved in a car accident and admitted to theEmergencyRoom with critical conditions.ACT scan showed hemopericardium, pneumomediastinum andD2 unstable vertebral fracture; then a sternotomy was promptly performed.After admittance toIntensiveCareUnit a bronchoscopy showed a tear of the posterior wall of the trachea and the complete disruption ofthe left main bronchus with a2 cm gap beetwen two consecutive cartilage rings.D2 fracture would have required stabilization, but pronation of the patient was contraindicated by the bronchial rupture.On the nineth day the vertebral fracture was stabilized, thus allowing a lateral decubitus and a left thoracotomy.The bronchial laceration was wrapped all around with a pedicled pericardial flap and a bronchial stent was placed inside the gap with a pediatric bronchoscope.Postoperative course was uneventful and the patient was transferred to thePhysicalRehabilitationUnit after23 d.The successful outcome of this case is the result of multidisciplinary management where every decision was shared by each specialist. From the surgical point of view survival is uncommon in such severe association of lesions.The use of pericardium wrap together with a bronchial stent represents an innovative solution to treat a complicated bronchial disruption.

    Full Text Available Background The prevalence of asthma in children has increased in many countries. Environmental factors are believed to play an important role and an inverse relationship between number of siblings and atopic disorders has been observed. Objective To assess for an association between bronchial asthma in atopic children and their number of siblings. Methods A cross-sectional study was conducted from June to November 2010 in three elementary schools in Medan, North Sumatera. Trace cards from the Allergy-Immunology Indonesian Pediatric Association (IDAI Working Group and questionnaires on the clinical history of atopy were used to screen children with the risk of atopy. The International Study of Asthma and Allergies in Childhood (ISAAC questionnaire to screen for bronchial asthma was distributed to children aged 7-10 years with a history of asthma, allergic rhinitis or atopic dermatitis. Subjects were divided into two groups, those with <3 siblings and those with ≥3 siblings. Chi-square test was used to analyze differences in bronchial asthma prevalence between the two groups. Results Ninety-six subjects enrolled in the study, with 48 subjects per group. The prevalence of bronchial asthma was significantly higher in atopic children who had <3 siblings than in children with ≥3 siblings (73.5% and 26.5%, respectively; P=0.04. Conclusion Bronchial asthma was significantly more frequent in children with less than 3 siblings compared to those with 3 or more siblings. [Paediatr Indones. 2014;54:289-93.].

    Lipopolysaccharides (LPS, the major part of endotoxins) are bacterial proinflammatory substances which can induce in asthmatic patients after inhalation a bronchial obstruction with an increase in both histamine bronchial hyperresponsiveness and blood inflammatory markers. The aim of the present study was to evaluate whether an acute inhalation of sodium cromoglycate, an anti-inflammatory and membrane-stabilizating agent, can block the LPS-induced lung function response. Using a double-blind placebo-controlled crossover method, 7 asthmatic subjects were submitted, at 4 days' interval, to a bronchial challenge test with either solvent solution or LPS (20 micrograms) preceded by inhalation of sodium cromoglycate (10 mg) or placebo. Compared to the solvent reaction, LPS induced a significant bronchial obstruction [measured by both the forced expiratory volume in 1 s (FEV1) and the airway resistances] beginning at the 60th minute and lasting more than 300 min (p sodium cromoglycate significantly inhibited the LPS-induced bronchial obstruction. The total lung capacity did not change significantly after LPS inhalation. Thus, this study showed that in asthmatics the LPS-induced FEV1 response is blocked by acute treatment with sodium cromoglycate. Sodium cromoglycate could be an active treatment in asthmatics exposed to house dust containing endotoxin.

    Recurrent lung infections and pneumonia are emerging as significant comorbidities in the HIV-infected population in the era of combination antiretroviral therapy (cART). HIV infection has been reported to suppress nasal mucociliary clearance (MCC). Since the primary components driving nasal MCC and bronchial MCC are identical, it is possible that bronchial MCC is affected as well. Effective MCC requires optimal ciliary beating which depends on the maintenance of the airway surface liquid (ASL), a function of cystic fibrosis transmembrane conductance regulator (CFTR) activity and the integrity of the signaling mechanism that regulates ciliary beating and fluid secretion. Impairment of either component of the MCC apparatus can compromise its efficacy and promote microbial colonization. We demonstrate that primary bronchial epithelium expresses HIV receptor CD4 and co-receptors CCR5 and CXCR4 and can be infected by both R5 and X4 tropic strains of HIV. We show that HIV Tat suppresses CFTR biogenesis and function in primary bronchial epithelial cells by a pathway involving TGF-β signaling. HIV infection also interferes with bronchial epithelial cell differentiation and suppresses ciliogenesis. These findings suggest that HIV infection suppresses tracheobronchial mucociliary clearance and this may predispose HIV-infected patients to recurrent lung infections, pneumonia and chronic bronchitis.

    Pallister-Killian syndrome is a rare syndrome of multiple congenital anomalies attributable to the presence of a mosaic supernumerary isochromosome (12p). Although the clinical manifestations of Pallister-Killian syndrome are variable, the most common anomalies include craniofacial dysmorphisms, limb deformities, progressive psychomotor development delay, severe hypotonia, and epilepsy. Standard karyotype is nearly always normal, but the isochromosome (12p) is present in a high percentage of skin fibroblasts. In this article, we report the case of 2 boys with Pallister-Killian syndrome having late-onset, drug-resistant epileptic spasms. Seizures have been reported in 40% of patients with Pallister-Killian syndrome but are poorly described. Epileptic spasms are not unusual in patients with brain malformations, chromosomal aberrations, and genetic syndromes, but epileptic spasms could be easily mistaken for behavioral manifestations. A better electroclinical characterization of epileptic seizures in Pallister-Killian syndrome using appropriate polygraphic tests (video-electroencephalography, electromyography) may lead to an early diagnosis and specific treatment for this form of epileptic spasms caused by this rare syndrome.

    Study of the chronobiology of allergic rhinitis (AR) and bronchial asthma (BA) and the chronopharmacology and chronotherapy of the medications used in their treatment began five decades ago. AR is an inflammatory disease of the upper airway tissue with hypersensitivity to specific environmental antigens, resulting in further local inflammation, vasomotor changes, and mucus hypersecretion. Symptoms include sneezing, nasal congestion, and runny and itchy nose. Approximately 25% of children and 40% of adults in USA are affected by AR during one or more seasons of the year. The manifestation and severity of AR symptoms exhibit prominent 24-h variation; in most persons they are worse overnight or early in the morning and often comprise nighttime sleep, resulting in poor daytime quality of life, compromised school and work performance, and irritability and moodiness. BA is also an inflammatory medical condition of the lower airways characterized by hypersensitivity to specific environmental antigens, resulting in greater local inflammation as well as bronchoconstriction, vasomotor change, and mucus hypersecretion. In USA an estimated 6.5 million children and 15.7 million adults have BA. The onset and worsening of BA are signaled by chest wheeze and/or croupy cough and difficult and labored breathing. Like AR, BA is primarily a nighttime medical condition. AR is treated with H1-antagonist, decongestant, and anti-inflammatory (glucocorticoid and leukotriene receptor antagonist and modifier) medications. Only H1-antagonist AR medications have been studied for their chronopharmacology and potential chronotherapy. BA is treated with some of the same medications and also theophylline and beta2-agonists. The chronopharmacology and chronotherapy of many classes of BA medications have been explored. This article reviews the rather extensive knowledge of the chronobiology of AR and BA and the chronopharmacology and chronotherapy of the various medications used in their treatment.

    An FTIR image of an 8 µm section of de-paraffinised bronchial biopsy that shows a histological transition from normal to severe dysplasia/squamous cell carcinoma (SCC) in situ was obtained in transmission by stitching together images of 256 x 256 µm recorded using a 96 x 96 element FPA detector. Each pixel spectrum was calculated from 128 co-added interferograms at 4 cm-1 resolution. In order to improve the signal to noise ratio, blocks of 4x4 adjacent pixels were subsequently averaged. Analyses of this spectral image, after conversion of the spectra to their second derivatives, show that the epithelium and the lamina propria tissue types can be distinguished using the area of troughs at either 1591, 1334, 1275 or 1215 cm-1 or, more effectively, by separation into two groups by hierarchical clustering (HCA) of the 1614-1465 region. Due to an insufficient signal to noise ratio, disease stages within the image could not be distinguished with this extent of pixel averaging. However, after separation of the cell types, disease stages within either the epithelium or the lamina propria could be distinguished if spectra were averaged from larger, manually selected areas of the tissue. Both cell types reveal spectral differences that follow a transition from normal to cancerous histology. For example, spectral changes that occurred in the epithelium over the transition from normal to carcinoma in situ could be seen in the 1200-1000 cm-1 region, particularly as a decrease in the second derivative troughs at 1074 and 1036 cm-1 , consistent with changes in some form of carbohydrate. Spectral differences that indicate a disease transition from normal to carcinoma in the lamina propria could be seen in the 1350-1175 cm-1 and 1125-1030 cm-1 regions. Thus demonstrating that a progression from healthy to severe dysplasia/squamous cell carcinoma (SCC) in situ can be seen using FTIR spectroscopic imaging and multivariate analysis.

    Exposure to cigarette smoke (CS) is linked to the development of respiratory diseases, and there is a need to understand the mechanisms whereby CS causes damage. Although animal models have provided valuable insights into smoking-related respiratory tract damage, modern toxicity testing calls for reliable in vitro models as alternatives for animal experimentation. We report on a repeated whole mainstream CS exposure of nasal and bronchial organotypic tissue cultures that mimic the morphological, physiological, and molecular attributes of the human respiratory tract. Despite the similar cellular staining and cytokine secretion in both tissue types, the transcriptomic analyses in the context of biological network models identified similar and diverse biological processes that were impacted by CS-exposed nasal and bronchial cultures. Our results demonstrate that nasal and bronchial tissue cultures are appropriate in vitro models for the assessment of CS-induced adverse effects in the respiratory system and promising alternative to animal experimentation.

    Objective: The aim of our study was to determine an optimal slice thickness that was efficient in revealing bronchial imageology of pulmonary nodules (PNs) on multi-slice spiral computed tomography (MSCT) images preliminarily. Methods: Fifty-four patients with 62 PNs (diameter ≤ 3 cm) underwent multidetector-row computed tomography of the chest in a single-breath-hold technique. The raw data were acquired with a collimation of 0.625 mm. Three sets of contiguous im-ages were reconstructed with 1-, 2-, and 5-mm slice thickness, respectively. Bronchial imageology of SPNs on the CT images presented in 1-, 2-, and 5-mm slice thickness was compared. Using the 1-mm sections as the gold standard, an optimal slice thickness in revealing bronchial imageology of PNs was determined. Results: Bronchial imageology of PNs on the CT im-ages presented in 1 mm slice thickness involved 85 bronchi (35 second-fourth generation bronchi; 50 fifth-eighth generation bronchi). Bronchial imageology on 2-mm-thick sections was as same as that on 1-mm-thick sections in 34 second- fourth generation bronchi. No statistically significant difference in number of second- fourth generation bronchi with same bronchial imageology was found between that on 2-mm-thick images and 1-mm-thick images (P = 0.836 > 0.05). Bronchial imageology on 5-mm-thick sections was as same as that on 1-mm-thick sections in 24 second-fourth generation bronchi. There was statistically significant difference in number of second-fourth generation bronchi with same bronchial imageology between that on 5-mm-thick images and 1-mm-thick images (P = 0.026 < 0.05). Bronchial imageology on 2-mm-thick sections was as same as that on 1-mm-thick sections in 38 fifth-eighth generation bronchi. There was statistically significant difference in number of fifth-eighth generation bronchi with same bronchial imageology between that on 2-mm-thick images and 1-mm-thick images (P = 0.029 < 0.05). Bronchial imageology on 5-mm-thick images was

    Bronchial stump fistula is a post-operative complication with poor outcome after pulmonary lobectomy. In order to prevent this complication, the bronchial stump is covered with pericardial fat tissue in our hospital. The case was 58 year old male who received adjuvant chemotherapy after sigmoidectomy for sigmoid colon cancer. As he developed multiple pulmonary metastases, 48 courses of chemotherapy were performed. The lesions had been localized at the right lower lobe, and neither increase in the size of these lesions nor development of other lesions were observed. Hence, an operation was performed. After right lower lobectomy, the bronchial stump was covered with the pericardial fat tissue. Three months after the operation, he developed pneumothorax, and bubbles were detected inside the fat. The pneumothorax was cured conservatively, and the bubbles disappeared spontaneously after 10 months. It is rare that the patient with bubbles in the covering tissue observed for a long time is cured conservatively, suggesting the significance of the stump pad.

    Full Text Available Infantile spasms is an age-specific epileptic syndrome associated with poor developmental outcomes and poor response to nearly all traditional antiepileptic drugs except adrenocorticotropic hormone (ACTH. We investigated the protective mechanism of ACTH against brain damage. An infantile spasm rat model induced by N-methyl-D-aspartate (NMDA in neonate rats was used. Pregnant rats were randomly divided into the stress-exposed and the non-stress exposed groups, and their offspring were randomly divided into ACTH-treated spasm model, untreated spasm model, and control groups. A proteomics-based approach was used to detect the proteome differences between ACTH-treated and untreated groups. Gel image analysis was followed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometric protein identification and bioinformatics analysis. Prenatal stress exposure resulted in more severe seizures, and ACTH treatment reduced and delayed the onset of seizures. The most significantly up-regulated proteins included isoform 1 of tubulin β-5 chain, cofilin-1 (CFL1, synaptosomal-associated protein 25, malate dehydrogenase, N(G,N(G-dimethylarginine dimethylaminohydrolase 1, annexin A3 (ANXA3, and rho GDP-dissociation inhibitor 1 (ARHGDIA. In contrast, tubulin α-1A chain was down-regulated. Three of the identified proteins, ARHGDIA, ANXA3, and CFL1, were validated using western blot analysis. ARHGDIA expression was assayed in the brain samples of five infantile spasm patients. These proteins are involved in the cytoskeleton, synapses, energy metabolism, vascular regulation, signal transduction, and acetylation. The mechanism underlying the effects of ACTH involves the molecular events affected by these proteins, and protein acetylation is the mechanism of action of the drug treatment.

    Familiarity with prevailing pattern and variations in the bronchial tree is not only essential for the anatomist to explain bronchial variation in bronchial specimens, but also useful for guiding bronchoscopy and instructing pulmonary segmental resection. The purpose of this study was designed to demonstrate various branching patterns of left lung with 3D images, with special attention given to identify the major types at transverse thin-section CT. Two hundred and sixteen patients with routine thorax scans were enrolled. The images of bronchial tree, virtual bronchoscopy were reconstructed using post-processing technique of multi-detector row CT. We attempted to classify the segmental bronchi by interpreting the post-processing images, and identified them in transverse thin-section CT. Our results showed that the segmental bronchial ramifications of the left superior lobe were classified into three types mainly, i.e., common stem of apical and posterior segmental bronchi (64%, 138/216); trifurcation (23%, 50/216); common stem of apical and anterior segmental bronchi (10%, 22/216), and they could be identified at two typical sections of transverse thin-section CT. There were two major types in left basal segmental bronchi, i.e., bifurcation (75%, 163/216), trifurcation (18%, 39/216), and they could also be identified at two typical sections of transverse thin-section CT. In conclusion, our study have offered simplified branching patterns of bronchi and demonstrated various unusual bronchial branching patterns perfectly with 3D images, and have also revealed how to identify the main branching patterns in transverse thin-section CT.

    Full Text Available Abstract Background Chronic obstructive pulmonary disease (COPD is characterized by abnormal lung inflammation that exceeds the protective response. Various culture models using epithelial cell lines or primary cells have been used to investigate the contribution of bronchial epithelium in the exaggerated inflammation of COPD. However, these models do not mimic in vivo situations for several reasons (e.g, transformed epithelial cells, protease-mediated dissociation of primary cells, etc.. To circumvent these concerns, we developed a new epithelial cell culture model. Methods Using non transformed non dissociated bronchial epithelium obtained by bronchial brushings from COPD and non-COPD smokers, we developed a 3-dimensional culture model, bronchial epithelial spheroids (BES. BES were analyzed by videomicroscopy, light microscopy, immunofluorescence, and transmission electron microscopy. We also compared the inflammatory responses of COPD and non-COPD BES. In our study, we chose to stimulate BES with lipopolycaccharide (LPS and measured the release of the pro-inflammatory mediators interleukin-8 (IL-8 and leukotriene B4 (LTB4 and the anti-inflammatory mediator prostaglandin E2 (PGE2. Results BES obtained from both COPD and non-COPD patients were characterized by a polarized bronchial epithelium with tight junctions and ciliary beating, composed of basal cells, secretory cells and ciliated cells. The ciliary beat frequency of ciliated cells was not significantly different between the two groups. Of interest, BES retained their characteristic features in culture up to 8 days. BES released the inflammatory mediators IL-8, PGE2 and LTB4 constitutively and following exposure to LPS. Interestingly, LPS induced a higher release of IL-8, but not PGE2 and LTB4 in COPD BES (p Conclusion This study provides for the first time a compelling evidence that the BES model provides an unaltered bronchial surface epithelium. More importantly, BES represent an

    We studied changes in lung volumes and in bronchial response to methacholine chloride (MC) challenge when antishock trousers (AST) were inflated at venous occlusion pressure in healthy subjects in the standing posture, a maneuver known to shift blood toward lung vessels. On inflation of bladders isolated to lower limbs, lung volumes did not change but bronchial response to MC increased, as evidenced by a greater fall in the forced expiratory volume in 1 s (FEV1) at the highest dose of MC used compared with control without AST inflation (delta FEV1 = 0.94 +/- 0.40 vs. 0.66 +/- 0.46 liter, P less than 0.001). Full inflation of AST, i.e., lower limb and abdominal bladder inflated, significantly reduced vital capacity (P less than 0.001), functional residual capacity (P less than 0.01), and FEV1 (P less than 0.01) and enhanced the bronchial response to MC challenge compared with partial AST inflation (delta FEV1 = 1.28 +/- 0.47 liter, P less than 0.05). Because there was no significant reduction of lung volumes on partial AST inflation, the enhanced bronchial response to MC cannot be explained solely by changes in base-line lung volumes. An alternative explanation might be a congestion and/or edema of the airway wall on AST inflation. Therefore, to investigate further the mechanism of the increased bronchial response to MC, we pretreated the subjects with the inhaled alpha 1-adrenergic agonist methoxamine, which has both direct bronchoconstrictor and bronchial vasoconstrictor effects.(ABSTRACT TRUNCATED AT 250 WORDS)

    Twenty-five cases of feline bronchial disease were identified retrospectively. The criteria for inclusion were consistent clinical signs or histopathology and no other identifiable aetiology. Patient records were analysed to determine historical, clinical, clinicopathologic and radiographic features. The main presenting complaints were coughing and dyspnoea. The most common physical finding was dyspnoea. The majority of radiographs had a bronchial pattern either as the sole change or as a component of a mixed pattern. Bronchoalveolar lavage cytology was neutrophilic or eosinophilic in the majority of cats. There was no association between age, breed, sex, clinical signs, bronchoalveolar lavage cytology or radiographic severity and disease severity.

    2011-03-01

    Full Text Available Clinical and epidemiological behaviour of bronchial asthma in elderlies is almost an unknown topic in the investigations carried out in the field, because studies conducted in adult population approach a single age group from 15 years old on. Bronchial asthma is considered a health problem given its high prevalence: about 10% of the Cuban population suffers from it. In elderlies it is an underdiagnosed and undertreated disease often confused with chronic lung disease, so it is very important to able to evaluate the specific characteristics it presents in elderlies in order to attack the disease effectively, and promote the life quality of asthmatic elderlies.

    Absent pulmonary valve syndrome (APVS) is a rare cardiac malformation with massive pulmonary insufficiency that presents with short-term and long-term respiratory problems secondary to severe bronchial compression from enlarged central and hilar pulmonary arteries. Association with chromosome 22.Q11 deletions and DiGeorge syndrome is common. This historical review illustrates the airway disease with emphasis on assessment of the bronchial compression in patients with persistent respiratory difficulties post-valvular repair. Cases that had MRI for cardiac assessment are used to illustrate the pattern of airway disease. (orig.)

    A 70-year-old man with a 3-year history of bronchiectasis presented with massive hemoptysis that had lasted for 3 days. In our attempt to perform bronchial artery embolization, upper abdominal angiography was required to locate the left bronchial artery, which in this case was of anomalous origin, arising from a replaced left hepatic artery, which arose from the left gastric artery-a very unusual anatomical variant. We performed embolization with polyvinyl alcohol particles, and the patient's symptoms resolved completely, with no additional complications after conservative treatment.

    Full Text Available Background/Aim. Physical activity is a common stimulus of asthmatic symptoms manifestation. Airway hyperreactivity is a predisposing cause of exercise induced bronchial obstruction, diagnosed by histamine inhalation. The aim of this study was to determine the relation between the amounts of histamine needed to induce non-specific airway hyperreactivity and exercise-induced bronchial obstruction. Methods. This randomized cross-over study included 160 male patients (age 19-27 years suffering from bronchial asthma who showed positive results as the reaction after the histamine bronchial provocation test. Histamine concentrations were in a range of 0.03 to 4 mg/mL. Each patient participated in the exercise stress test conducted on a conveyor belt. The results of the exercise stress test were considered positive if the FEV1 level dropped by at least 15% from its initial value, 5-10 minutes after the test. Results. All the patients showed positive results as the reaction after the histamine bronchial provocation test, while 50 of them showed positive results after the exercise-induced stress test. There was a statistically highly significant difference in administrated histamine concentrations between the group of patients that had positive results on exercise stress test and those who did not (1mg/mL vs 0.5mg/mL; U = 1678; p < 0.01. Also, there was a statistically significant difference concerning the frequency of the positive results regarding histamine concentration after induced stress test (χ2 = 10.885; p = 0.001. Among the patients with positive results, there was a statistically highly significant number of patients with bronchial obstruction induced by less than 2 mg/mL of histamine (p < 0.01. A statistically significant relation between the amount of histamine needed to induce bronchial obstruction and the results of the exercise stress test (p < 0.01 was also observed after the testing. Conclusion. In the group of patients with positive

    Autoantibodies that bind to voltage-gated potassium-channel complex proteins (VGKC-complex antibodies) occur frequently in adults with limbic encephalitis presenting with cognitive impairment and seizures. Recently, VGKC-complex antibodies have been described in a few children with limbic encephalitis, and children with unexplained encephalitis presenting with status epilepticus. We report a case of infantile-onset epileptic spasms and developmental delay compatible with epileptic encephalopathy. Our patient was a female infant, aged 4 months at presentation. She had evidence of immune activation in the central nervous system with elevated cerebrospinal fluid neopterin and mirrored oligoclonal bands, which prompted testing for autoantibodies. VGKC-complex antibodies were elevated (201 pmol/L, normalVGKC-complex antibodies might represent a marker of immune therapy responsiveness in a subgroup of patients with infantile epileptic encephalopathy.

    Botulinum toxin type-A is currently thought to be effective and safe for hemifacial spasm (HFS). The pre-synaptic block of acetylcholine release at the neuromuscular junction induces depression of orbicularis oculi muscle compound motor action potential (CMAP). The aim of our study was to evaluate at what extent end-plate functional recovery is possible even in botulinum toxin treatments lasting up to 15 years. We examined 81 outpatients with primary HFS (mean treatment duration = 7.2 ± 4.2 years) who underwent neurophysiologic study, once clinical effect of the previous treatment had vanished. The mean CMAP amplitude, mean rectified amplitude of response 1 (R1) of the blink reflex and area of response 2 (R2) of treated orbicularis oculi muscle were measured in comparison to the controlateral side. Mean amplitude of the above mentioned parameters was slightly lower (about 20%; p muscle complex.

    Objectives: The aim of this study is to review the available literature on the efficacy and safety of agents used for prevention of RAS. Background: Different vasodilator agents have been used to prevent radial artery spasm (RAS) in patients undergoing transradial cardiac catheterization. Methods: We included studies that evaluated any intra-arterial drug administered in the setting cardiac catheterization that was undertaken through the transradial access site (TRA). We also compared studies for secondary outcomes of major bleeding, procedure time, and procedure failure rate in setting of RAS prevention, patent hemostasis and radial artery occlusion. Results: 22 clinical studies met the inclusion criteria. For placebo, RAS rate was 12% (4 studies, 638 participants), which was similar to 2.5 mg of verapamil 12% (3 studies, 768 participants) but greater than 5 mg of verapamil (4%, 2 studies, 497 participants). For nicorandil, there was a much higher RAS rate compared to placebo (16%, 3 studies, 447 participants). The lowest rates of RAS was found for nitroglycerin at both 100 μg (4%) and 200 μg (2%) doses, isosorbide mononitrate (4%) and nicardipine (3%). We found no information regarding the procedure failure rates, patent hemostasis, and radial artery occlusion in these studies. Conclusions: In this largest and up-to-date review on intra-arterial vasodilators use to reduce RAS, we have found that the verapamil at a dose of 5 mg or verapamil in combination with nitroglycerine are the best combinations to reduce RAS. - Highlights: • Radial artery spasm (RAS) causes procedural failure in transradial catheterization. • RAS may complicate 10–15% procedures undertaken through the radial approach. • We reviewed the efficacy of vasodilators that have been used to minimize RAS. • The pooled RAS rate was lowest with 5 mg of verapamil (4%) compared to placebo (12%). • The best combination of drugs to minimize RAS is nitroglycerine and verapamil.

    The objective of this study is to explore the cause of early abnormal muscle response (AMR) disappearance during microvascular decompression for hemifacial spasm and the clinical outcomes of these patients. Three hundred seventy-two patients received microvascular decompression (MVD) under intraoperative electrophysiological monitoring in Nanjing Drum Tower Hospital in 2014; the characteristic AMR of HFS was observed in 359 patients during the operation. And the 359 patients were divided into two groups based on whether AMR had remained before the beginning of the decompression procedure for offending vessels. Thirty-three patients who showed a permanent disappearance of AMR before the beginning of decompression were regarded as group I. Dural opening and the succeeding CSF drainage produced a permanent disappearance of AMR in 13. During the dissection of lateral cerebellomedullary cistern, a permanent disappearance of AMR was found in 20 patients. Thirty-two patients were cured immediately; delayed resolution (7 days after surgery) was found in one patient. No complications were observed and no recurrence was found during the follow-up period in the 33 patients. In the other 326 patients (group II), AMR disappeared temporarily before the beginning of the decompression procedure for offending vessels in 42 patients. After decompression, AMR disappeared completely in 305 patients. Two hundred sixty-seven patients were cured immediately and 57 patients got a delayed resolution (2 days to 45 weeks after surgery). The two left did not get a complete abolition of spasm. Three cases of hearing loss, one hoarseness, and nine delayed facial paralysis were observed. The reason of early abnormal muscle response disappearance may be that the degree of neurovascular compression was not serious; these patients were more likely to get an immediate cure. Continuous intraoperative electrophysiological monitoring of AMR is necessary.

    Full Text Available Abstract Background Inflammatory cytokines (e.g. IL-13 and mechanical perturbations (e.g. scrape injury to the epithelium release profibrotic factors such as TGF-β2, which may, in turn, stimulate subepithelial fibrosis in asthma. We hypothesized that prolonged IL-13 exposure creates a plastic epithelial phenotype that is profibrotic through continuous secretion of soluble mediators at levels that stimulate subepithelial fibrosis. Methods Normal human bronchial epithelial cells (NHBE were treated with IL-13 (0, 0.1, 1, or 10 ng/ml for 14 days (day 7 to day 21 following seeding at an air-liquid interface during differentiation, and then withdrawn for 1 or 7 days. Pre-treated and untreated NHBE were co-cultured for 3 days with normal human lung fibroblasts (NHLF embedded in rat-tail collagen gels during days 22–25 or days 28–31. Results IL-13 induced increasing levels of MUC5AC protein, and TGF-β2, while decreasing β-Tubulin IV at day 22 and 28 in the NHBE. TGF-β2, soluble collagen in the media, salt soluble collagen in the matrix, and second harmonic generation (SHG signal from fibrillar collagen in the matrix were elevated in the IL-13 pre-treated NHBE co-cultures at day 25, but not at day 31. A TGF-β2 neutralizing antibody reversed the increase in collagen content and SHG signal. Conclusion Prolonged IL-13 exposure followed by withdrawal creates an epithelial phenotype, which continuously secretes TGF-β2 at levels that increase collagen secretion and alters the bulk optical properties of an underlying fibroblast-embedded collagen matrix. Extended withdrawal of IL-13 from the epithelium followed by co-culture does not stimulate fibrosis, indicating plasticity of the cultured airway epithelium and an ability to return to a baseline. Hence, IL-13 may contribute to subepithelial fibrosis in asthma by stimulating biologically significant TGF-β2 secretion from the airway epithelium.

    1992-09-01

    Among modern physiologists and anatomists, there has been a nearly universal acceptance that Leonardo da Vinci was the first to identify the anatomy of the bronchial circulation. However, because of certain ambiguities in both his anatomic drawing that was supposed to have shown this circulation and the accompanying descriptive text, we questioned whether he really could have been the first to discover this small but important vasculature. To address this question, we set out to repeat Leonardo's dissections in the ox. We reasoned that perhaps the normally tiny bronchial vessels would be considerably more noticeable in this very large species. Our dissections, however, failed to provide any evidence that Leonardo's drawing was that of the bronchial circulation. Furthermore we observed a set of distinct small pulmonary veins to the left upper and right middle lobes that Leonardo, given his lack of understanding of the function of the lung and its circulation, could have easily mistaken for a separate circulation. We thus conclude that Leonardo da Vinci did not describe the anatomy of the bronchial circulation. We believe that the first person to clearly and unequivocally describe the anatomy of this circulation was the Dutch Professor of Anatomy and Botany, Frederich Ruysch.

  3. Anti-apoptotic effects of Z alpha1-antitrypsin in human bronchial epithelial cells.

    alpha(1)-antitrypsin (alpha(1)-AT) deficiency is a genetic disease which manifests as early-onset emphysema or liver disease. Although the majority of alpha(1)-AT is produced by the liver, it is also produced by bronchial epithelial cells, amongst others, in the lung. Herein, we investigate the effects of mutant Z alpha(1)-AT (ZAAT) expression on apoptosis in a human bronchial epithelial cell line (16HBE14o-) and delineate the mechanisms involved. Control, M variant alpha(1)-AT (MAAT)- or ZAAT-expressing cells were assessed for apoptosis, caspase-3 activity, cell viability, phosphorylation of Bad, nuclear factor (NF)-kappaB activation and induced expression of a selection of pro- and anti-apoptotic genes. Expression of ZAAT in 16HBE14o- cells, like MAAT, inhibited basal and agonist-induced apoptosis. ZAAT expression also inhibited caspase-3 activity by 57% compared with control cells (p = 0.05) and was a more potent inhibitor than MAAT. Whilst ZAAT had no effect on the activity of Bad, its expression activated NF-kappaB-dependent gene expression above control or MAAT-expressing cells. In 16HBE14o- cells but not HEK293 cells, ZAAT upregulated expression of cIAP-1, an upstream regulator of NF-kappaB. cIAP1 expression was increased in ZAAT versus MAAT bronchial biopsies. The data suggest a novel mechanism by which ZAAT may promote human bronchial epithelial cell survival.

METHODS Study conducted with 61 adults in Lima, Peru, from January 2006 to December 2007. The yield of sputum cultures was compared with the yield of acid-fast bacilli smears and cultures of bronchial washing for diagnosing pulmonary tuberculosis in suspected cases of clinical tuberculosis with negative acid fast bacilli sputum smears. RESULTS Twenty seven (95%CI 32;58 of the cases were eventually diagnosed with smear-negative pulmonary tuberculosis. Bronchial washing samples detected 23 (95%CI 72;99 of the smear-negative pulmonary tuberculosis cases compared with 15 (95%CI 37;74 for sputum cultures (p = 0.02. The incremental diagnostic yield of acid fast bacilli smear and culture of bronchial washing specimens over sputum culture was 44% (95%CI 25;65. CONCLUSIONS In function of the epidemiological context and the resources available, bronchoscopy should be deployed as part of a comprehensive work up that optimizes smear-negative pulmonary tuberculosis diagnosis and minimizes risk and costs.

    Full Text Available By dopplerechocardiography method there was studied functional state of cardiac ventricles and character of hemodynamic disorders in 48 patients aged 5-17 years in attack period of moderately-severe and severe bronchial asthma. Group of comparison included 40 healthy peers. Disorders of central and peripheral hemodynamic in attack period of bronchial asthma in children were accompanied both by systolic and diastolic dysfunction of the left and right heart ventricles, herewith right ventricle was functioning in the mode of hyperdynamic, and left one – in the mode of hypodynamic. Combined systolic-diastolic variant of dysfunction both of right and left ventricles was developing in 58,3% of patients with moderately-severe and in 91,6% of patients with severe bronchial asthma. In the attack period of bronchial asthma in children equal directionality of systolic and diastolic dysfunction of heart ventricles was developing; this was characterized by synchronization of their function. Assessment of functional interaction of the ventricles under conditions of severe asthma attack showed direct and high (r=0,67 correlative interaction between finding of Tei index of the left and right ventricles, which characterize their systolic function; this, under conditions of increased hemodynamic pre-loading testified to compensatory increase of systolic interaction of ventricles. Direct and high (r=0,69 correlative interaction between time indices of isovolumic relaxation of the left and right ventricles, characterizing their diastolic function, testified to compensatory increase of diastolic interaction of ventricles under conditions of increase of hemodynamic post-loading. Imbalance of central and peripheral link of hemodynamic in attack period of bronchial asthma in children testified to development of cardiac insufficiency, which was compensated predominantly at the expense of increase of heart contractions rate.

    Full Text Available Life-threatening hemoptysis is one the most challenging condition encountered in critical care. Bronchial artery embolization (BAE has become an established procedure, in the management of massive and recurrent hemoptysis. Bronchial arteries have variable anatomy. The reported prevalence of bronchial arteries with an anomalous origin ranges from 8.5 -35%. We are describing two patients who presented with hemoptysis and were effectively managed with bronchial artery embolization. Both these patients had anomalous origin of bronchial artery from the internal mammary artery, one from the Right Internal Mammary Artery (RIMA and one from the Left Internal Mammary Artery (LIMA. The procedures were performed under general anesthesia. In the first case a double lumen endobronchial tube was used while in the second case, the patient was managed without tracheal intubation. The first patient was dyspnoeic; saturation was poor and was unable to maintain her airway probably due to profuse blood in her airways. We used a double lumen tube in her to isolate the diseased lung from the healthier lung. We gave her muscle relaxants and mechanical ventilation so that a stable lung field could be provided during embolization. The second patient was quite stable and comfortable while breathing room air. We decided not to interfere with his airway. A back-up plan and preparation for urgent airway control and lung isolation was done inside the catheterization laboratory.From the management point of view, an unstable patient with life-threatening hemorrhage needs airway control and lung isolation. A stable patient with minimum to moderate bleeding may be managed safely under general anesthesia with the patient spontaneously breathing.

    AIM: To examine the effects of rhinovirus and lipopolysaccharide (LPS) on mucin secretion from bronchial tissue and epithelial cells in vitro. METHODS: Human small bronchial tissue fragments (HSBTF) and human bronchial epithelial cells (HBEC) were cultured with rhinovirus 16 and LPS, respectively and culture supernatants were collected for mucin measurement. To determine mucin levels in the culture supernatants, a MUC5AC enzyme linked immunosorbent assay and an enzyme linked lectin assay procedure with dolichos bifiorus agglutinin (DBA)were developed, and mucin release was expressed as percentage increased (or decreased) secretion over baseline level. RESULTS: A concentration-dependent release of DBA mucin and MUC5AC mucin were observed when HSBTF were infected with various concentrations of rhinovirus 16 at 37 ℃. The maximum-induced DBA mucin and MUC5AC mucin release were approximately 258 % and 83 % over baseline. The response of HSBTF to rhinovirus was completely abolished by metabolic inhibitors. Rhinovirus was also able to induce a concentrationdependent release of DBA mucin and MUC5AC mucin from primarily cultured HBEC. LPS 100 mg/L was able to provoke up to approximately 19 % and 54 % increase in DBA and MUC5AC mucin release over baseline, respectively from HSBTF, and 3.1% and 57 % increase from HBEC at 20 h. Soybean trypsin inhibitor (SBTI) 30 mg/L was able to inhibit LPS-induced mucin release from HSBTF and HBEC. CONCLUSION: Rhinovirus is able to induce mucin secretion from human bronchial tissue and bronchial epithelial cells in vitro. LPS can induce MUC5AC mucin release from HSBTF and HBEC.

    Fusiform aneurysm as a cause of hemifacial spasm (HFS) is an extremely rare condition. A 69-year-old man developed paroxysmal spasm of his left side facial muscles over a period of 5 years. Radiologic images demonstrated a left vertebral artery (VA) fusiform aneurysm compressing the root entry zone of the left facial nerve. The patient underwent serial surgical procedures for the treatment of HFS under intraoperative electromyography monitoring. Lateral spread response (LSR) did not disappear despite 5 minutes of extracranial left VA ligation and remained after cerebrospinal fluid drainage after dura opening. After interposition of the VA through Teflon felt insertion, the LSR finally disappeared. The patient became symptom free immediately after the surgery and continued as such throughout a follow-up period of 1 year. This is the first report involving real-time monitoring of the LSR changes resulting from serial procedures of decompression in an HFS caused by a fusiform aneurysm of the VA.

    The objective of this study was to evaluate phentolamine as radial artery spasmolytic in transradial catheterization procedures. Radial artery spasm is a relatively frequent complication during transradial approach, causing patient discomfort or even making it impossible to continue the procedure. As radial artery spasm is mediated by the stimulation of alpha-adrenoreceptors, the use of the alpha-blocker phentolamine could make sense as spasmolytic. We designed a randomized double-blind study to compare phentolamine vs. verapamil, the standard spasmolytic agent. Five hundred patients (250 in each arm) submitted to a transradial cardiac catheterization were consecutively included and randomly assigned to receive 2.5 mg of verapamil or 2.5 mg of phentolamine after sheath insertion. Both vasodilator agents induced a significant radial artery diameter increase (from 2.22 +/- 0.53 to 2.48 +/- 0.57 mm, P phentolamine). However, verapamil was more efficacious to prevent radial artery spasm (13.2% compared with 23.2% in phentolamine-treated patients; P = 0.004). Follow-up (20 +/- 18 days) evaluation of the radial artery patency by plestismography and pulse oximetry showed no differences between the two groups in the rate of radial occlusion (3.0% vs. 3.2% in verapamil and phentolamine treated patients, respectively). Phentolamine was an effective radial vasodilator agent, although it showed less ability to prevent radial artery spasm than verapamil. Radial artery occlusion rate was almost identical for both vasodilators. Thus, phentolamine could be a valid alternative to verapamil as a radial artery spasmolytic agent.

    Objective: High resolution computed tomography (HRCT) was used to assess the extent of bronchial reactivity after inhalative bronchoprovocation and dilation in hyperresponsive patients and healthy subjects. Patients and methods: Patients with mild intermittent asthma, 15 with a >20% decrease in FEV{sub 1} and a >10 mmHg (PC{sub 20}+) in PaO{sub 2}, 12 with a <20% decrease in FEV{sub 1} and a >10 mmHg (PC{sub 20}-) in PaO{sub 2} after provocation, and eight healthy humans were included in the study. Changes in cross-sectional area in a total of 1256 bronchi and in bronchial wall area (792 bronchi) were evaluated after histamine-triggered bronchoprovocation and salbutamol-induced bronchodilation at high lung volumes (FVC 80%). Data were compared with the results of pulmonary function tests (FEV{sub 1}, PaO{sub 2}, PaCO{sub 2}). Results: In all groups, a significant decrease in bronchial cross-sectional area (P<0.001) and a significant increase in bronchial wall area (P<0.001) were observed subsequent to bronchoprovocation. After bronchodilation, the increase in cross-sectional area (P<0.001) and the further increase in airway wall area (P<0.01) were significant in all groups. In PC{sub 20}+ and PC{sub 20}- asthmatics, significant differences (P<0.05) in PaO{sub 2}, >10 mmHg between baseline and provocation were observed. In healthy persons, the PaO{sub 2} decrease was <10 mmHg (P>0.05). After histamine provocation, the decrease in FEV{sub 1} was measured in the PC{sub 20}+ group, whereas a <20% FEV{sub 1} decrease was found in the PC{sub 20}- and the control groups, respectively. No significant correlations were observed between radiological data and the results of pulmonary function tests. Conclusions: HRCT demonstrated bronchial reactivity in hyperresponsive patients and, unexpectedly, in healthy subjects. The applied pulmonary function tests failed to characterize bronchial reactions in the healthy subjects. Based on these results, HRCT is a useful tool by which

  4. NGF is an essential survival factor for bronchial epithelial cells during respiratory syncytial virus infection.

    Full Text Available Overall expression of neurotrophins in the respiratory tract is upregulated in infants infected by the respiratory syncytial virus (RSV, but it is unclear where (structural vs. inflammatory cells, upper vs. lower airways and why, these changes occur. We analyzed systematically the expression of neurotrophic factors and receptors following RSV infection of human nasal, tracheal, and bronchial epithelial cells, and tested the hypothesis that neurotrophins work as innate survival factors for infected respiratory epithelia.Expression of neurotrophic factors (nerve growth factor, NGF; brain-derived neurotrophic factor, BDNF and receptors (trkA, trkB, p75 was analyzed at the protein level by immunofluorescence and flow cytometry and at the mRNA level by real-time PCR. Targeted siRNA was utilized to blunt NGF expression, and its effect on virus-induced apoptosis/necrosis was evaluated by flow cytometry following annexin V/7-AAD staining.RSV infection was more efficient in cells from more distal (bronchial vs. more proximal origin. In bronchial cells, RSV infection induced transcript and protein overexpression of NGF and its high-affinity receptor trkA, with concomitant downregulation of the low-affinity p75(NTR. In contrast, tracheal cells exhibited an increase in BDNF, trkA and trkB, and nasal cells increased only trkA. RSV-infected bronchial cells transfected with NGF-specific siRNA exhibited decreased trkA and increased p75(NTR expression. Furthermore, the survival of bronchial epithelial cells was dramatically decreased when their endogenous NGF supply was depleted prior to RSV infection.RSV infection of the distal airway epithelium, but not of the more proximal sections, results in overexpression of NGF and its trkA receptor, while the other p75(NTR receptor is markedly downregulated. This pattern of neurotrophin expression confers protection against virus-induced apoptosis, and its inhibition amplifies programmed cell death in the infected

    A battery of non-oncogenically immortalized human bronchial epithelial cells (HBECs) are being used to examine the molecular changes that lead to lung carcinogenesis after exposure to heavy particles found in the free space environment. The goal is to ultimately identify biomarkers of radioresponse that can be used for prediction of carcinogenic risk for fatal lung cancer. Our initial studies have focused on the cell line HBEC3 KT and the isogenic variant HBEC3 KTR53, which overexpresses the RASv12 mutant and where p53 has been knocked down by shRNA, and is considered to be a more oncogenically progressed variant. We have previously described the response of HBEC3 KT at the cellular and molecular level, however, the focus here is on the rate of cellular transformation after HZE radiation exposure and the molecular changes in transformed cells. When comparing the two cell lines we find that there is a maximum rate of cellular transformation at 0.25 Gy when cells are exposed to 1 GeV Fe particles, and, for the HBEC3 KTR53 there are multiple pathways upregulated that promote anchorage independent growth including the mTOR pathway, the TGF-1 pathway, RhoA signaling and the ERK/MAPK pathway as early as 2 weeks after radiation. This does not occur in the HBEC3 KT cell line. Transformed HBEC3 KT cells do not show any morphologic or phenotypic changes when grown as cell cultures. HBEC3 KTR53 cells on the other hand show substantial changes in morphology from a cobblestone epithelial appearance to a mesenchymal appearance with a lack of contact inhibition. This epithelial to mesenchymal change in morphology is accompanied by the expression of vimentin and a reduction in the expression of E-cadherin, which are hallmarks of epithelial to mesenchymal transition. Interestingly, for HBEC3 KT transformed cells there are no mutations in the p53 gene, 2 of 15 clones were found to be heterozygous for the RASV12 mutation, and 3 of 15 clones expressed high levels of BigH3, a TGFB

    The occurrence of an anastomosis between the coronary artery to the systemic artery is rare. However, the probability of hemodynamic changes sufficient to cause clinical symptoms is extremely low. Anastomosis of the coronary to bronchial artery can cause myocardial ischemia due to the decreased flow to the coronary arteries. The authors report a case of coronary to bronchial artery anastomosis presenting as coronary steal syndrome that was treated with transarterial microcoil embolization instead of surgical ligation.

    2016-01-01

    Brain and spinal injury reduce mobility and often impair sensorimotor processing in the spinal cord leading to spasticity. Here, we establish that complete transection of corticospinal pathways in the pyramids impairs locomotion and leads to increased spasms and excessive mono- and polysynaptic low threshold spinal reflexes in rats. Treatment of affected forelimb muscles with an adeno-associated viral vector (AAV) encoding human Neurotrophin-3 at a clinically-feasible time-point after injury reduced spasticity. Neurotrophin-3 normalized the short latency Hoffmann reflex to a treated hand muscle as well as low threshold polysynaptic spinal reflexes involving afferents from other treated muscles. Neurotrophin-3 also enhanced locomotor recovery. Furthermore, the balance of inhibitory and excitatory boutons in the spinal cord and the level of an ion co-transporter in motor neuron membranes required for normal reflexes were normalized. Our findings pave the way for Neurotrophin-3 as a therapy that treats the underlying causes of spasticity and not only its symptoms. DOI: http://dx.doi.org/10.7554/eLife.18146.001 PMID:27759565

    Asthma and other respiratory diseases have increased in the last years among Venezuelan children from helminthic endemic areas where the infection by Ascaris lumbricoides has been associated to bronchial airway inflammation in parasitized individuals. The aim of this work was to investigate the possible associations between the development of bronchial hyper reactivity and the immune response against A. lumbricoides in urban and rural children. We evaluated 470 school children from rural and urban communities. Pulmonary function tests were performed and >or=20% PC(20) changes were considered as a positive diagnostic of bronchial hyper reactivity. The prevalence and intensity of A. lumbricoides infection was determined by faecal examination. Specific serum IgE levels using a modified ELISA and skin prick tests against A. lumbricoides and the common allergen Dermatophagoides pteronyssinus were done. The number of circulating lymphocyte sub populations was determined by flow cytometry analysis. In rural children, bronchial hyper reactivity was associated with increased specific levels of anti-A. lumbricoides IgE (plumbricoides (plumbricoides IgE levels. Elevated numbers of circulating CD3+CD4+ and CD20+CD23+ cells were found in rural children with bronchial hyper reactivity compared to their asymptomatic counterparts. They correlated positively with anti-A. lumbricoides IgE levels (plumbricoides infection may be involved in the development of bronchial hyper reactivity among rural children from endemic areas and also that improved hygienic conditions in the urban environment is associated with increased responses to airborne allergens.

    Full Text Available We observed sixty patients with allergic bronchial asthma (ABA and 54 with non-allergic bronchial asthma (NABA. Quantitative SOCS3 and SOCS5 mRNA expression was evaluated by means of real-time PCR. Eighteen healthy persons served as a control group. In patients with bronchial asthma (irrespectively of pathogenetic form, a significant increase of SOCS3 transcription factor expression was detected in peripheral blood mononuclears, as compared with control group. This increase was more pronounced in NABA group. The mRNA SOCS5 level was significantly decreased in bronchial asthma patients, as compared to control group, especially, in ABA subgroup rather than in NABA patients. Thus, an increased expression of SOCS3 mRNA in BA patients could be regarded as a protective antiinflammatory response Decrease of SOCS5 mRNA expression in patients with bronchial asthma (being more pronounced in ABA, may be indicative for a deficiency in negative feedback regulation of gene transcription in allergic bronchial asthma.

    Human rhinoviruses have been linked with underlying lung disorders, such as asthma and chronic obstructive pulmonary disease, in children and adults. However, the mechanism of virus-induced airway inflammation is poorly understood. In this study, using virus deletion mutants and silencing for nucleotide-binding oligomerization domain-like receptors (NLRs), we show that the rhinovirus ion channel protein 2B triggers NLRP3 and NLRC5 inflammasome activation and IL-1β secretion in bronchial cells. 2B protein targets the endoplasmic reticulum and Golgi and induces Ca(2+) reduction in these organelles, thereby disturbing the intracellular calcium homeostasis. NLRP3 and NLRC5 act in a cooperative manner during the inflammasome assembly by sensing intracellular Ca(2+) fluxes and trigger IL-1β secretion. These results reveal for the first time that human rhinovirus infection in primary bronchial cells triggers inflammasome activation.

  15. "Bronchial Artery Delivery of Viral Vectors for Gene delivery in Cystic Fibrosis; Superior to Airway Delivery?"

    Directory of Open Access Journals (Sweden)

    Coutelle Charles C

    2002-04-01

    Full Text Available Abstract Background Attempts at gene therapy for the pulmonary manifestations of Cystic Fibrosis have relied mainly on airway delivery. However the efficiency of gene transfer and expression in the airway epithelia has not reached therapeutic levels. Access to epithelial cells is not homogenous for a number of reasons and the submucosal glands cannot be reached via the airways. Presentation We propose to inject gene delivery vectors directly into bronchial arteries combined with pre-delivery of vascular endothelial growth factor to increase vascular endothelial permeability and post-delivery flow reduction by balloon occlusion. Thus it may be possible to reach mucous secreting cells of the bronchial luminal epithelium and the submucosal glands in an increased and homogenous fashion. Testing This combination of techniques to the best of our knowledge has not previously been investigated, and may enable us to overcome some of the current limitations to gene therapy for Cystic Fibrosis.

    Hedgehog interacting protein (HHIP) was implicated in chronic obstructive pulmonary disease (COPD) by genome-wide association studies (GWAS). However, it remains unclear how HHIP contributes to COPD pathogenesis. To identify genes regulated by HHIP, we performed gene expression microarray analysis in a human bronchial epithelial cell line (Beas-2B) stably infected with HHIP shRNAs. HHIP silencing led to differential expression of 296 genes; enrichment for variants nominally associated with COPD was found. Eighteen of the differentially expressed genes were validated by real-time PCR in Beas-2B cells. Seven of 11 validated genes tested in human COPD and control lung tissues demonstrated significant gene expression differences. Functional annotation indicated enrichment for extracellular matrix and cell growth genes. Network modeling demonstrated that the extracellular matrix and cell proliferation genes influenced by HHIP tended to be interconnected. Thus, we identified potential HHIP targets in human bronchial epithelial cells that may contribute to COPD pathogenesis.

    Eighteen patients with bronchial asthma were studied in a single-blind fashion. Each patient received an infusion of magnesium sulfate (MgSO4.7H2O 50% W/V) in a dose equivalent to 10 mmol of elemental magnesium. The airways resistance showed a significant decrease (p significantly (p V50 (p statistically significant increase (p Significant changes in Raw (p significant side effects were observed with MgSO4 infusion. It is concluded that modest improvement in airways resistance and specific conductance and only small improvement in maximal expiratory flow rates is consistent with a predominant effect of MgSO4 on large airways in patients with bronchial asthma.

    1996-01-01

    Full Text Available The aim of the present study was to compare, during the pollen season, serum levels of total IgE and soluble CD23 (sCD23 from patients with allergic bronchial asthma, with those from healthy subjects. Significantly higher levels of total IgE and sCD23 were found in patients with asthma compared to the control group. Both in normal controls and in asthmatic patients, a significant correlation was shown between the levels of these two molecules. In asthmatic patients, significant correlations were found for both total IgE and sCD23, with lung function measured as bronchial responsiveness to inhaled methacholine. These results suggest that in asthmatic patients, in addition to the study of total serum IgE levels, the assessment of sCD23 serum levels may be helpful in the evaluation of disease activity.

  19. Successful Endobronchial stenting for bronchial compression from a massive thoracic aortic aneurysm

    Directory of Open Access Journals (Sweden)

    David Comer

    2010-06-01

    Full Text Available A case of bronchial occlusion caused by a thoracic aortic aneurysm and the relief of this obstruction by the implantation of expandable metallic stents is described. Stent deployment provided an immediate improvement in lung ventilation and chest radiograph appearances. Stent insertion was uncomplicated, but weaning from mechanical ventilation was unsuccessful and the patient died from a ventilator-associated pneumonia, unrelated to the procedure. Endobronchial stenting should be considered as a non-invasive therapy for the treatment of bronchial obstruction, with respiratory compromise, caused by a thoracic aortic aneurysm when vascular surgery is not an option. The medium to long term survival of this patient group is poor. This can be attributed to complications related to the stent and also to the poor performance status of these patients.

  20. Is platelet activating factor (PAF an important mediator in bronchial asthma?

    Directory of Open Access Journals (Sweden)

    R. H. Gundel

    1992-01-01

    Full Text Available The development of selective PAF receptor antagonists may provide a novel approach to the treatment of human bronchial asthma. In preclinical animal models of human asthma, PAF receptor antagonists have been found to be efficacious in blocking antigen-induced changes in lung function. However, the majority of these models involve acute inflammatory events and transient changes in lung function and, therefore, their relevance to human asthma is questionable. In a recent study with a primate model of chronic airway inflammation and hyperresponsiveness, we have shown that treatment with a PAF receptor antagonist had no effect on reducing chronic inflammation and hyperresponsiveness. Similarly, recent studies in human asthmatics with PAF receptor antagonists have failed to show efficacy in blocking allergen-induced airway responses or to have any steroid sparing effects in patients with ongoing asthma. Thus, it seems that PAF may not be a key mediator which can be blocked and thereby provide therapy for bronchial asthma.

    It is often difficult to expose the pulmonary artery buried in a scar tissue, especially in lung cancer patients that responded well to neoadjuvant chemoradiotherapy. Difficulty to access pulmonary artery branches may lead to potentially unnecessary pneumonectomy. To complete lobectomy in such cases, a technique with preceding bronchial cutting for exposure of the pulmonary artery is presented. After dissecting the pulmonary vein, the lobar bronchus is cut from the opposite side of the pulmonary artery with scissors. The back wall of the lobar bronchus is cut using a surgical knife from the luminal face, which can expose the pulmonary artery behind the bronchial stump and then complete lobectomy. Fourteen patients have been treated using the present technique, enabling complete resection by lobectomy (including sleeve lobectomy in 3 patients) without major bleeding. The present procedure can expose pulmonary artery buried in scar tissue, resulting in making the lobectomy safer.

    BACKGROUND: Studies of children's blood lipid profiles in relation to asthma are few, and the results are ambiguous. OBJECTIVE: We sought to examine whether the lipid profile is associated with concurrent asthma, altered lung function, and allergic sensitization in children. METHODS: High...... with assessments of lung function, bronchial responsiveness, fraction of exhaled nitric oxide (Feno), and allergic sensitization. Associations between lipid levels and clinical outcomes were adjusted for sex, passive smoking, and body mass index. RESULTS: High levels of low-density lipoprotein cholesterol were...... of increased Feno levels (aβ coefficient, 0.14 log-ppb; 95% CI, -0.02 to 0.30 log-ppb; P = .08). CONCLUSION: The blood lipid profile is associated with asthma, airway obstruction, bronchial responsiveness, and aeroallergen sensitization in 7-year-old children. These findings suggest that asthma and allergy...

  3. Alternative spliced CD1d transcripts in human bronchial epithelial cells.

    Directory of Open Access Journals (Sweden)

    Kambez Hajipouran Benam

    Full Text Available CD1d is a MHC I like molecule which presents glycolipid to natural killer T (NKT cells, a group of cells with diverse but critical immune regulatory functions in the immune system. These cells are required for optimal defence against bacterial, viral, protozoan, and fungal infections, and control of immune-pathology and autoimmune diseases. CD1d is expressed on antigen presenting cells but also found on some non-haematopoietic cells. However, it has not been observed on bronchial epithelium, a site of active host defence in the lungs. Here, we identify for the first time, CD1D mRNA variants and CD1d protein expression on human bronchial epithelial cells, describe six alternatively spliced transcripts of this gene in these cells; and show that these variants are specific to epithelial cells. These findings provide the basis for investigations into a role for CD1d in lung mucosal immunity.

    Rho GTPases regulate multiple signaling pathways to control a number of cellular processes during epithelial morphogenesis. To investigate the downstream pathways through which Rho regulates epithelial apical junction formation, we screened a small interfering RNA (siRNA) library targeting 28 known Rho target proteins in 16HBE human bronchial epithelial cells. This led to the identification of the serine-threonine kinase PRK2 (protein kinase C-related kinase 2, also called PKN2). Depletion of...

    The aim of the study was to clarify the relationships between bronchial asthma (BA), chronic obstructive pulmonary disease (COPD), and type 1 diabetes mellitus. Reduced prevalence of concomitant BA and DM1 suggests inverse relation between the two conditions and their mutually exclusive nature. The problem needs further studies. Taking into account age-specific and other features of COPD and DM1 pathological processes elucidation of their interrelation appears impractical.

    We studied the relationship between bronchopulmonary pathology (chronic pulmonary disease, CPD, and bronchial asthma, BA) and type 2 diabetes (DM2). The two conditions were shown to be underlain by inflammation of different character. In patients with CPD it leads to DM2. Concomitant CPD and BA significantly increase the risk of DM2 and require the development of measures for its diagnosis and prevention.

    Bilateral lung transplantation was performed in a 52-year old man with end-stage Kartagener's syndrome. A postimplantation right lower lobectomy was required for volume reduction and dextrocardia. A bronchial fistula developed with an intractable colonized residual pleural cavity. Closure was obtained successfully with multiple-stage procedures including decortication, muscle flap and an open-window thoracostomy without modification of the immunosuppressive protocol.

  9. Mechanisms of aldehyde-induced bronchial reactivity: role of airway epithelium

    1992-02-01

    To investigate the relative irritant potencies of inhaled aldehydes, guinea pigs were exposed to formaldehyde or acrolein and specific total pulmonary resistance and bronchial reactivity to intravenous acetylcholine were assessed. The mechanisms associated with these responses were investigated by analyzing morphologic and biochemical changes in airway epithelial cells after in vivo and in vitro exposures. Immediately after exposure to formaldehyde or acrolein, specific resistance increased transiently and returned to control values within 30 to 60 minutes. Bronchial hyperreactivity, assessed by the acetylcholine dose necessary to double resistance, increased and became maximal two to six hours after exposure to at least 9 parts per million2 (ppm) formaldehyde or at least 1 ppm acrolein for two hours. The effect of exposure to 3 ppm formaldehyde for two hours was less than the effect of exposure to 1 ppm formaldehyde for eight hours; thus, extended exposures produced a disproportionate heightening of bronchial reactivity. Bronchial hyperreactivity often persisted for longer than 24 hours. Increases in three bronchoconstrictive eicosanoids, prostaglandin F2 alpha, thromboxane B2, and leukotriene C4, occurred immediately after exposure, whereas an influx of neutrophils into lavage fluid occurred 24 hours later. Histological examination of the tracheal epithelium and lamina propria also demonstrated a lack of inflammatory cell infiltration. Treatment with leukotriene synthesis inhibitors and receptor antagonists inhibited acrolein-induced hyperreactivity, supporting a causal role for these compounds in this response. Acrolein also stimulated eicosanoid release from bovine epithelial cells in culture. However, the profile of metabolites formed differed from that found in lavage fluid after in vivo exposure.

    Bronchial colonization by potentially pathogenic microorganisms (PPMs) is often demonstrated in chronic obstructive pulmonary disease (COPD), but culture-based techniques identify only a portion of the bacteria in mucosal surfaces. The aim of the study was to determine changes in the bronchial microbiome of COPD associated with the severity of the disease. The bronchial microbiome of COPD patients was analyzed by 16S rRNA gene amplification and pyrosequencing in sputum samples obtained during stable disease. Seventeen COPD patients were studied (forced expiratory volume in the first second expressed as a percentage of the forced vital capacity [FEV1%] median, 35.0%; interquartile range [IQR], 31.5 to 52.0), providing a mean of 4,493 (standard deviation [SD], 2,598) sequences corresponding to 47 operational taxonomic units (OTUs) (SD, 17) at a 97% identity level. Patients were dichotomized according to their lung function as moderate to severe when their FEV1% values were over the median and as advanced when FEV1% values were lower. The most prevalent phyla in sputum were Proteobacteria (44%) and Firmicutes (16%), followed by Actinobacteria (13%). A greater microbial diversity was found in patients with moderate-to-severe disease, and alpha diversity showed a statistically significant decrease in patients with advanced disease when assessed by Shannon (ρ = 0.528; P = 0.029, Spearman correlation coefficient) and Chao1 (ρ = 0.53; P = 0.028, Spearman correlation coefficient) alpha-diversity indexes. The higher severity that characterizes advanced COPD is paralleled by a decrease in the diversity of the bronchial microbiome, with a loss of part of the resident flora that is replaced by a more restricted microbiota that includes PPMs.

    Focal areas of FDG uptake may occur at the bronchial stump following curative lobectomy for non-small-cell lung carcinoma (NSCLC), even in the absence of suspicious CT changes. The purpose of our study was to investigate the significance of such PET/CT findings. FDG-PET/CT scans performed in 54 patients after lobectomy for NSCLC were reviewed. The presence of focal areas of FDG uptake at the bronchial stump, associated CT abnormalities, SUVmax, and normalized SUV (SUVnorm = SUVmax/mean liver SUV) were recorded. Final diagnosis was based on biopsy or imaging follow-up. Focal areas of FDG uptake at the bronchial stump were detected in 30 patients (56 %). Mean SUVmax was 4.0 ± 1.9 (range; 2.2-12.1) and mean SUVnorm was 1.8 ± 0.8 (range; 0.9-4.5). Biopsy showed recurrence in two patients. In these patients, SUVnorm was respectively 4.4 and 4.5 (with SUVmax of 8.8 and 12.1), whereas SUVnorm was lower than 4.0 in those without recurrence, with mean SUVnorm of 1.6 ± 0.5 (range; 0.9-3.4) and mean SUVmax of 3.6 ± 0.9 (range; 2.2-5.8). The CT component of the PET/CT revealed ill-defined peribronchial soft tissue opacity only in both patients with recurrence. FDG uptake at the bronchial stump is a frequent finding after pulmonary lobectomy. Moderate levels of FDG uptake (i.e., SUVnorm < 4.0) without corresponding abnormal CT findings might be a dual criterion for diagnosing benign post-surgical changes. (orig.)

    We studied the characteristics of the rhythmicity of heart rate (HR), body temperature (BT), locomotor activity (LA) and autonomic nervous activity in bronchial-hypersensitive (BHS) and bronchial-hyposensitive (BHR) guinea pigs. For this purpose, HR, BT, LA, and electrocardiogram (ECG) were recorded from conscious and unrestrained guinea pigs using a telemetry system. Autonomic nervous activity was analyzed by power spectral analysis of heart rate variability. Nocturnal patterns, in which the values in the dark phase (20:00-06:00) were higher than those in the light phase (06:00-20:00), were observed in HR, BT and LA in both strains of guinea pigs. The autonomic nervous activity in BHS guinea pigs showed a daily pattern, although BHR guinea pigs did not show such a rhythmicity. The high frequency (HF) power in BHS guinea pigs was higher than that in BHR guinea pigs throughout the day. Moreover, the low frequency/high frequency (LF/HF) ratio in BHS guinea pigs was lower than that in BHR guinea pigs throughout the day. These results suggest that parasympathetic nervous activity may be predominant in BHS guinea pigs.

    Objective: To evaluate the clinical value of serum and bronchial aspiration fluid HE-4 levels in patients with lung cancer.Methods:A total of 58 patients with lung cancer and 40 with benign lung disease were enrolled in our study. Compare the serum and bronchial aspiration fluid HE-4 levels between the two group. The specificity and sensitivity of serum and bronchial aspiration fluid HE-4 levels in determine whether lung cancer or not were analyzed by receiver operating characteristic (ROC) curve; Spearman was used to evaluate the association of clinical and pathologic features with levels of LYVE-1.Results: Serum HE-4 levels were significantly higher in patients with lung cancer group than in benign lung disease group. No significant difference was observed in terms of BAF HE-4 values in two patient groups. The areas under the receiver operating characteristic (ROC) curve of serum HE-4 was 0.798 and that of BAF HE-4 was 0.598. A high cancer staging, occurrence of lymph-node metastases, and occurrence of distant metastases patient were associated with high HE-4 levels. No significant difference was observed with sex, tumor location and tumor histology.Conclusion: The increase of level of serum HE-4 is more prominent than the increase of the level of BAF HE-4, and has certain clinical significance for diagnosis of lung cancer and occurrence of metastases.

    Current models of carcinogenesis suggest that tissues progress through multiple genetic and epigenetic changes which ultimately lead to development of invasive cancer. Epidemiologic studies of Peto, R.R. and J.A. Doll indicate that the accumulation of these genetic changes over time, rather than any single unique genetic change, is probably responsible for development of the malignant phenotype. The bronchial epithelium of cigarette smokers is diffusely exposed to a broad spectrum of carcinogens, toxicants, and tumor promoters contained in tobacco smoke. This exposure increases the risk of developing multiple, independent premalignant foci throughout the lower respiratory tract that may contain independent gene aberrations. This {open_quotes}field cancerization{close_quotes} theory is supported by studies that have demonstrated progressive histologic changes distributed throughout the lower respiratory tract of smokers. A series of autopsy studies demonstrated that cigarette smokers exhibit premalignant histologic changes ranging from hyperplasia and metaplasia to severe dysplasia and carcinoma in situ diffusely throughout the bronchial mucosa. The proximal bronchi appear to exhibit the greatest number of changes, particularly at bifurcations. The results described are the first to quantitate the frequency for a chromosome aberration in {open_quotes}normal{close_quotes} bronchial epithelial cells.

  19. Endocytosis of Multiwalled Carbon Nanotubes in Bronchial Epithelial and Mesothelial Cells

    Directory of Open Access Journals (Sweden)

    Kayo Maruyama

    2015-01-01

    Full Text Available Bronchial epithelial cells and mesothelial cells are crucial targets for the safety assessment of inhalation of carbon nanotubes (CNTs, which resemble asbestos particles in shape. Intrinsic properties of multiwalled CNTs (MWCNTs are known to cause potentially hazardous effects on intracellular and extracellular pathways. These interactions alter cellular signaling and affect major cell functions, resulting in cell death, lysosome injury, reactive oxygen species production, apoptosis, and cytokine release. Furthermore, CNTs are emerging as a novel class of autophagy inducers. Thus, in this study, we focused on the mechanisms of MWCNT uptake into the human bronchial epithelial cells (HBECs and human mesothelial cells (HMCs. We verified that MWCNTs are actively internalized into HBECs and HMCs and were accumulated in the lysosomes of the cells after 24-hour treatment. Next, we determined which endocytosis pathways (clathrin-mediated, caveolae-mediated, and macropinocytosis were associated with MWCNT internalization by using corresponding endocytosis inhibitors, in two nonphagocytic cell lines derived from bronchial epithelial cells and mesothelioma cells. Clathrin-mediated endocytosis inhibitors significantly suppressed MWCNT uptake, whereas caveolae-mediated endocytosis and macropinocytosis were also found to be involved in MWCNT uptake. Thus, MWCNTs were positively taken up by nonphagocytic cells, and their cytotoxicity was closely related to these three endocytosis pathways.

    2005-10-01

    Full Text Available Abstract Background Human rhinoviruses (RV, the most common triggers of acute asthma exacerbations, are considered not cytotoxic to the bronchial epithelium. Recent observations, however, have questioned this knowledge. The aim of this study was to evaluate the ability of RV to induce epithelial cytotoxicity and affect epithelial repair in-vitro. Methods Monolayers of BEAS-2B bronchial epithelial cells, seeded at different densities were exposed to RV serotypes 1b, 5, 7, 9, 14, 16. Cytotoxicity was assessed chromatometrically. Epithelial monolayers were mechanically wounded, exposed or not to RV and the repopulation of the damaged area was assessed by image analysis. Finally epithelial cell proliferation was assessed by quantitation of proliferating cell nuclear antigen (PCNA by flow cytometry. Results RV1b, RV5, RV7, RV14 and RV16 were able to induce considerable epithelial cytotoxicity, more pronounced in less dense cultures, in a cell-density and dose-dependent manner. RV9 was not cytotoxic. Furthermore, RV infection diminished the self-repair capacity of bronchial epithelial cells and reduced cell proliferation. Conclusion RV-induced epithelial cytotoxicity may become considerable in already compromised epithelium, such as in the case of asthma. The RV-induced impairment on epithelial proliferation and self-repair capacity may contribute to the development of airway remodeling.

    2000-06-01

    Bronchial asthma is a common disease in both the pediatric and adult populations, characterized by wide variations over short periods of time in resistance to airflow in intrapulmonary airways. A primary goal in the use of low- level laser therapy (LLLT) was the safe, effective and rapid palliation of symptoms owing to tracheal or bronchial obstruction. We have investigated the effects of LLLT comparatively with other modality trials in children's asthma. In the study were included 98 patients aged 10-18 years diagnosed with moderate or severe asthma, in attack- free period. The patients were divided into 3 groups. Group 1 received only laser therapy using extra meridian acupuncture points and scanning technique. Group 2 was treated only with inhaled Serevent 2 X 25 micrometers , two times daily, 3 months. Group 3 was tread with Theophylline retard in dosage of 15-mg/kg/12 h, 3 months. At the end of treatment we remarked a noticeable improvement of the clinical, functional and immunological characteristics at 83 percent of patients in group 1, comparatively with only 70 percent (group 2) and 53 percent (group 3). The LLLT had a very good action on bronchial patency , displayed an immunocorrecting action and is recommended in attack-free periods at children.

    Objective To evaluate the preliminaily clinical efficacy and retrievability of a retrievable hinged covered metallic stent in the treatment of the bronchial stump fistula (BSF). Methods Between April 2003 and March 2005, 8 patients with bronchial stump fistula after pneumonectomy or lobectomy were treated with two types (A and B) of retrievable hinged covered metallic stents. Type A stent was placed in 6 patients and type B in 2 under fluoroscopic guidance. The stent was removed with a retrieval set when BSF was healed or complications occurred. Results Stent placement in the bronchial tree was technically successful in all patients, without procedure-related complications. Immediate closure of the BSF was achieved in all patients after the procedure. Stents were removed from all patients but one. Removal of the stents was difficult in two patients due to tissue hyperplasia. Patients were followed up for 6 - 21 months. Placement of the stents remained stable in all patients except one due to severe cough. Permanent closure of BSF was achieved in 7(87.5%) of 8 patients. Conclusion Use of a retrievable hinged covered expandable metallic stent is a simple,safe, and effective procedure for closure of the BSF. Retrieval of the stent seems to be feasible.

    2016-05-01

    There is an unmet need for new therapies in severe persistent asthma. Bronchial thermoplasty is a bronchoscopic procedure which employs radiofrequency energy to reduce airway smooth muscle and has been demonstrated to improve symptomatic control in severe persistent asthma in other populations. Seven patients have completed bronchial thermoplasty at a tertiary referral centre in Ireland. Asthma Control Test scores and data on hospitalisations, exacerbations, maintenance corticosteroid requirements, rescue bronchodilator use and peak expiratory flow rate (PEFR) were compared one year before and one year post treatment. Significant improvements were demonstrated in mean Asthma Control Test scores, from 8.9 to 14.7 (p = 0.036). Trends towards improvement were seen in mean hospitalisations (respective values for total in 12 month period 5.0, 0.9; p = 0.059) and PEFR (181.4 l\\/min, 280 l\\/min respectively; p = 0.059). These data support the use of bronchial thermoplasty in severe persistent asthma in the Irish population.

    Isolated unilateral pulmonary artery agenesis is a rare congenital anomaly that may be complicated with hemoptysis, recurrent pulmonary infections or pulmonary hypertension. To our knowledge the occurrence of a coronary syndrome associated with a coronary-to-bronchial artery saccular aneurysmal collateralization has never been described before. A 44-year-old female presented a congenital right pulmonary artery agenesis associated with a hypotrophic and multicystic right lung complicated with recurrent bronchitis. This patient had a coronary syndrome for which the coronary artery imaging showed a coronary-to-bronchial artery collateralization with an aneurysm at this level. It gives rise to a coronary syndrome by coronary steal. Two bronchial collaterals arising from a diaphragmatic artery and the subclavian artery were also found on the computed tomography (CT)-scan. This last collateral also showed another saccular aneurysm. We first performed an embolization of those two aneurysms in order to decrease the risk of hemorrhage and coronary steal, before performing a right pneumonectomy. In this case, the surgery was indicated because of the pathological lung and the risk of postembolization ischaemia. The postoperative course was uneventful and the patient was doing well six months later.

    The interpretation of experimental results from functional medical imaging is complicated by intersubject and interspecies differences in airway geometry. The application of computational models in understanding the significance of these differences requires methods for generation of subject-specific geometric models of the bronchial airway tree. In the current study, curvilinear airway centerline and diameter models have been fitted to human and ovine bronchial trees using detailed data segmented from multidetector row X-ray-computed tomography scans. The trees have been extended to model the entire conducting airway system by using a volume-filling algorithm to generate airway centerline locations within detailed volume descriptions of the lungs or lobes. Analysis of the geometry of the scan-based and model-based airways has verified their consistency with measures from previous anatomic studies and has provided new anatomic data for the ovine bronchial tree. With the use of an identical parameter set, the volume-filling algorithm has produced airway trees with branching asymmetry appropriate for the human and ovine lung, demonstrating the dependence of the method on the shape of the lung or lobe volume. The modeling approach that has been developed can be applied to any level of detail of the airway tree and into any volume shape for the lung; hence it can be used directly for different individuals or animals and for any number of scan-based airways. The resulting models are subject-specific computational meshes with anatomically consistent geometry, suitable for application in simulation studies.

    Early detection and localisation of bronchial cancer remains a challenging task. One approach is to exploit the changes in the autofluorescence characteristics of the bronchial tissue as a diagnostic tool with improved sensitivity. Evidence exists that this native fluorescence or autofluorescence of bronchial tissues changes when they turn dysplastic and to carcinoma in situ. There is an agreement in the literature that the lesions display a decrease of autofluorescence in the green region of the spectrum under illumination with violet light and a relative increase in the red region of the spectrum is often reported. Imaging devices rely on this principle to detect early cancerous lesions in the bronchi. Based on a previous spectroscopic study, an industrial imaging prototype has been developed to detect early cancerous lesions in collaboration with the firm 'Richard Wolf Endoskope GmbH'. A preliminary clinical trial involving 20 patients with this spectrally optimised system proved that autofluorescence can detect lesions that would otherwise have remained invisible even to an experienced endoscopist under white light illumination. A systematic analysis of the autofluorescence images pointed out that real-time decisional functions can be defined in order to reduce the number of false positive results. Using this method, a Positive Predictive Value (PPV) of 75% was achieved using autofluorescence only. A PPV of even 100% were obtained when white light mode and autofluorescence mode were combined under the applied conditions. Furthermore, the sensitivity was estimated to be twice as high in AF mode than in WL mode.

    Cigarette smoking contributes to the pathogenesis of chronic obstructive pulmonary disease and lung cancer. Nicotine-derived nitrosamine ketone (NNK) is the most potent carcinogen among cigarette smoking components, and is known to enhance migration of cancer cells. However, the effect of NNK on normal human bronchial epithelial cells is not well studied. XB130 is a member of actin filament associated protein family and is involved in cell morphology changes, cytoskeletal rearrangement and outgrowth formation, as well as cell migration. We hypothesized that XB130 mediates NNK-induced migration of normal human bronchial epithelial cells. Our results showed that, after NNK stimulation, XB130 was translocated to the cell periphery and enriched in cell motility-associated structures, such as lamellipodia, in normal human bronchial epithelial BEAS2B cells. Moreover, overexpression of XB130 significantly enhanced NNK-induced migration, which requires both the N- and C-termini of XB130. Overexpression of XB130 enhanced NNK-induced protein tyrosine phosphorylation and promoted matrix metalloproteinase-14 translocation to cell motility-associated cellular structures after NNK stimulation. XB130-mediated NNK-induced cell migration may contribute to airway epithelial repair; however, it may also be involved in cigarette smoking-related chronic obstructive pulmonary disease and lung cancer.

    Objective: To determine whether the severity of non-neurological critically ill patients correlates with clinical predictors of bronchial aspiration. Methods: We evaluated adults undergoing prolonged orotracheal intubation (> 48 h) and bedside swallowing assessment within the first 48 h after extubation. We collected data regarding the risk of bronchial aspiration performed by a speech-language pathologist, whereas data regarding the functional level of swallowing were collected with the American Speech-Language-Hearing Association National Outcome Measurement System (ASHA NOMS) scale and those regarding health status were collected with the Sequential Organ Failure Assessment (SOFA). Results: The study sample comprised 150 patients. For statistical analyses, the patients were grouped by ASHA NOMS score: ASHA1 (levels 1 and 2), ASHA2 (levels 3 to 5); and ASHA3 (levels 6 and 7). In comparison with the other patients, those in the ASHA3 group were significantly younger, remained intubated for fewer days, and less severe overall clinical health status (SOFA score). The clinical predictors of bronchial aspiration that best characterized the groups were abnormal cervical auscultation findings and cough after swallowing. None of the patients in the ASHA 3 group presented with either of those signs. Conclusions: Critically ill patients 55 years of age or older who undergo prolonged orotracheal intubation (≥ 6 days), have a SOFA score ≥ 5, have a Glasgow Coma Scale score ≤ 14, and present with abnormal cervical auscultation findings or cough after swallowing should be prioritized for a full speech pathology assessment.

    Objective To explore the toxicological mechanism of hydroquinone in human bronchial epithelial cells and to investigate whether DNA polymerase beta is involved in protecting cells from damage caused by hydroquinone. Methods DNA polymerase beta knock-down cell line was established via RNA interference as an experimental group. Normal human bronchial epithelial cells and cells transfected with the empty vector of pEGFP-Cl were used as controls. Cells were treated with different concentrations of hydroquinone (ranged from 10 μmol/L to 120 μmol/L) for 4 hours. MTT assay and Comet assay [single-cell gel electrophoresis (SCGE)] were performed respectively to detect the toxicity of hydroquinone. Results MTT assay showed that DNA polymerase beta knock-down cells treated with different concentrations of hydroquinone had a lower absorbance value at 490 nm than the control cells in a dose-dependant manner. Comet assay revealed that different concentrations of hydroquinone caused more severe DNA damage in DNA polymerase beta knock-down cell line than in control cells and there was no significant difference in the two control groups. Conclusions Hydroquinone has significant toxicity to human bronchial epithelial cells and causes DNA damage. DNA polymerase beta knock-down cell line appears more sensitive to hydroquinone than the control cells. The results suggest that DNA polymerase beta is involved in protecting cells from damage caused by hydroquinone.

    Objective: In this work, effect of tamsulosin as antagonist of alpha1A and alpha1B adrenergic receptor and effect of agonists of beta2 adrenergic receptor–salbutamol in patients with increased bronchial reactibility was studied. Methods: Parameters of the lung function are determined with Body plethysmography six (6) hours after administration of tamsulosin. Raw and ITGV were registered and specific resistance (SRaw) was calculated as well. Tamsulosin was administered in per os manner as a preparation in the shape of the capsules with a brand name of “Prolosin”, produced by Niche Generics Limited, Hitchin, Herts. Results: After six (6) hours of administration of tamsulosin, results gained indicate that blockage of alpha1A and alpha1B-adrenergic receptor (0.8 mg per os) has not changed significantly (p > 0.1) the bronchomotor tonus of tracheobronchial tree in comparison to the check-up that has inhaled salbutamol agonist of adrenergic beta2 receptor (2 inh. x 0.2 mg), (p < 0.05). Blood pressure suffered no significant decrease following administration of the 0.8 mg dose of tamsulosin. Conclusion: This suggests that even after six hours of administration of tamsulosin, and determining of lung function parameters, the activity of alpha1A and alpha1B-adrenergic receptor in the smooth bronchial musculature has not changed in patients with increased bronchial reactibility.

    Full Text Available Over years,great strides have been made in theories and practices of mechanical ventilation.The indications of non-invasive ventilation have been increasing,while invasive ventilation has been playing a vital role in patients who are critically ill with inadequate drainage of sputum and fail to benefit from non-invasive ventilation.Chronic diseases,including chronic obstructive pulmonary disease(COPD,one of the most common chronic diseases,and bronchial asthma,the incidence of which is ascending recent years,are main causes for respiratory failure.Accordingly,we focus in the present paper on discussion and elaboration of respiratory failure as a result of COPD and bronchial asthma.Type II respiratory failure is the major type of respiratory failure induced by COPD,both in acute exacerbation and stable stage,and mechanical ventilation is one of the most common treatments.Severe acute bronchial asthma complicated with respiratory failure is an emergency.In this situation,primary goal of mechanical ventilation is to make an efficient oxygenation and ventilation of patients,and to avoid hyperinflation to the utmost.For patients who are able to cooperate,non-invasive ventilation in early stage may be beneficial,avoiding tracheal intubation and application of invasive ventilation.But in those who can not achieve remission in a short term,an artificial airway should be established for invasive ventilation as soon as possible.

    We review here the literature on neuroendocrine neoplasms metastatic to the pituitary and present an example of the disease. Metastasis of bronchial carcinoid tumors to the sellar region are rare. Herein, we describe the case of a 63-year-old woman who presented with constant cough and headaches. She had previously been operated for carcinoid tumor of the lung. During the preoperative investigation, a CT scan of the head revealed a sellar mass. Six months after a left lower lobectomy, the sellar lesion was removed by transsphenoidal surgery. The two tumors were evaluated by histology, immunohistochemistry and electron microscopy. Both showed identical morphologic features, those of carcinoid tumor. Immunohistochemistry revealed immunoreactivity for the endocrine markers, synaptophysin and chromogranin, as well as CD-56, serotonin, bombesin and vascular endothelial growth factor. The sellar neoplasm showed nuclear immunopositivity for thyroid transcription factor-1, supporting the diagnosis of a metastatic bronchial carcinoid tumor. In conclusion, this is the first report of a serotonin- and bombesin-immunopositive atypical bronchial carcinoid tumor metastatic to the sella.

    Purpose: To characterize parenchymal lung affections morphologically in patients with asthma and healthy subjects by high resolution computed tomography (HRCT) subsequent to histamine-triggered inhalation bronchoprovocation and salbutamolinduced broncholysis, and to compare the results with pulmonary function tests. Materials and Methods: Fifteen asthmatics with bronchial hyperreactivity, with a>20% decrease in FEV1 and a>10 mmHg decrease in PaO{sub 2} after bronchoprovocation (PC20%+), twelve asthmatics with a<20% decrease in FEV1 and a>10 mmHg decrease in PaO{sub 2} after bronchoprovocation (PC20%-), and eight healthy persons without bronchial hyperreactivity underwent inhalation bronchoprovocation and broncholysis. Spirometer-triggered HRCT at high lung volumes was performed, and total and peripheral lung densities and the amount of solid lung structures, representing predominantly vessels, were measured. Results: After bronchoprovocation, we observed significant decreases in total and peripheral lung densities in all groups (p<0.0005), and a significant increase in lung densities subsequent to bronchodilation (p<0.0002). The morphological alterations in solid lung structure were not significantly different after bronchoprovocation or broncholysis (p>0.05), as compared to the baseline measurements. In hyperreactive patients, PaO{sub 2} significantly decreased after provocation and significantly increased after lysis (p<0.05). In PC20%+ asthmatics, a mean reduction of 27.8% in FEV1 was observed, which was <20% in the other groups. No significant correlations were observed between radiological data and the results of pulmonary function tests. In healthy persons, we demonstrated highly significant parenchymal response to bronchoprovocation and broncholysis, which was not otherwise documented by pulmonary function tests. Conclusion: In both PC20%+ and PC20%- patients as well as in healthy individuals, HRCT was efficient in the evaluation of pathoanatomical

    BACKGROUND: Recent researches have demonstrated that baclofen is a commonly central anti-spasm drug. In addition, neural facilitation technique based on nerve development and neurophysiology is widely used for rehabilitation training of motor disorder after central nerve injury. However, whether baclofen combining with neural facilitation technique can relieve muscular spasm after spinal cord injury needs further studies.OBJECTIVE: To observe the effect of baclofen combining with neural facilitation technique on decreasing muscular tension in two lower extremities after spinal cord injury.DESIGN: Randomized controlled study.SETTING: Departments of Rehabilitation and Orthopaedics, the Third Affiliated Hospital of Guangzhou Medical College.PARTICIPANTS: A total of 28 patients with spinal cord injury, including 17 males and 11 females, whose age ranged from 31 to 71 years, were selected from Departments of Rehabilitation and Orthopaedics, the Third Affiliated Hospital of Guangzhou Medical College from March 2005 to September 2006. The illness course ranged from 22 to 54 days and the mean course was (38 ± 8) days. All patients were diagnosed as the first onset and the increase of extensor muscular tension in two lower extremities after thoracic vertebra injury by using spine MR or CT examination. Informed consents were obtained from all the patients.METHODS: All 28 patients who had upper motor neuronal paralysis in two lower extremities after spinal cord injury in thoracic vertebra region were randomly divided into treatment group and control group with 14 cases in each group. Patients in both groups received routine therapy, while those in the treatment group were treated with oral baclofen (the beginning dosage: 5 mg/time; three times per day, 5 mg was increased every three days; the maximal dosage was 60 mg/day; 6 weeks in total) (made in Weicai Pharmaceutical Co., Ltd.;tablet; batch number: HC20040029) combining with neural facilitation technique, which accorded

    Bronchial hygiene therapy is a standard part of the treatment of patients with cystic fibrosis (CF). Coughing alone promotes sputum expectoration and is probably the primary effective component of standard bronchial hygiene therapy. The purpose of this study was to determine whether substituting regular exercise, which also promotes coughing, for two of three daily bronchial hygiene treatments would affect the expected improvements in pulmonary function and exercise response in hospitalized patients with CF. Seventeen patients with CF hospitalized (means length of stay = 13.0 +/- 2.6 days) for an acute exacerbation of their pulmonary disease participated in the study. The patients were randomly assigned to either a group that participated in two cycle ergometer exercise sessions and one bronchial hygiene treatment session per day (EX Group [n = 9]) or a group that participated in three bronchial hygiene treatment sessions per day (PD Group [n = 8]). Pulmonary functions and responses to a progressive, incremental cycle ergometer exercise test were measured on admission and before discharge. Bronchial hygiene therapy consisted of postural drainage, in six positions, with chest percussion and vibration. Therapeutic exercise was of moderate intensity and was individually adjusted based on the patient's heart rate and arterial oxygen saturation response to the admission exercise test. Coughing was encouraged during and after all treatments. Pulmonary function and exercise response were significantly improved over the period of hospitalization in both groups; the improvements were the same in the two groups. These results indicate that, in some hospitalized patients with CF, exercise therapy may be substituted for at least part of the standard protocol of bronchial hygiene therapy.

    We show how neurosurgical planning can benefit from the better visualization of the precise vascular compression of the nerve provided by the oblique-sagittal and gradient-echo method (OS-GR image) using magnetic resonance images (MRI). The scans of 3 patients with trigeminal neuralgia (TN) and of 15 with hemifacial spasm (HFS) were analyzed for the presence and appearance of the vascular compression of the nerves. Imaging sequences consisted of an OS-GR image (TR/TE: 200/20, 3-mm-thick slice) cut along each nerve shown by the axial view, which was scanned at the angle of 105 degrees taken between the dorsal line of the brain stem and the line corresponding to the pontomedullary junction. In the OS-GR images of the TN's, the vascular compressions of the root entry zone (REZ) of the trigeminal nerve were well visualized as high-intensity lines in the 2 cases whose vessels were confirmed intraoperatively. In the other case, with atypical facial pain, vascular compression was confirmed at the rostral distal site on the fifth nerve, apart from the REZ. In the 15 cases of HFS, twelve OS-GR images (80%) demonstrated vascular compressions at the REZ of the facial nerves from the direction of the caudoventral side. During the surgery for these 12 cases, in 11 cases (excepting the 1 case whose facial nerve was not compressed by any vessels), vascular compressions were confirmed corresponding to the findings of the OS-GR images. Among the 10 OS-GR images on the non-affected side, two false-positive findings were visualized. It is concluded that OS-GR images obtained by means of MRI may serve as a useful planning aid prior to microvascular decompression for cases of TN and HFS. (author).

    We investigated 100 consecutive patients with trigeminal neuralgia (TN) and 53 patients with hemifacial spasm (HFS) concerning the anatomical relationship between the root entry (exit) zone (REZ) of cranial nerve and the offending artery, using spoiled GRASS MRI (SPGR-MRI) and three dimensional-time of fly-MRA (MRA). In 67 of 100 (67%) patients with TN, this new radiological method, SPGR-MRI and MRA demonstrated the relationship between the fifth cranial nerve root and offending artery causing neurovascular compression (NVC), and in 46 of 53 (87%) with HFS, demonstrated the similar relationship between seventh and eighth nerve complex and offending artery. Microvascular decompression (MVD) was performed in 10 with HFS, and NVC of the REZ of the facial nerve caused by the offending artery was exactly predicted by SPGR-MRI and MRA in 9 (90%). The combination of SPGR-MRI and MRA is very useful for demonstrating NVC as the cause of TN and HFS. On the other hand, we investigated asymptomatic 206 trigemimal and 253 facial nerves about the relationship between their REZ and the surrounding structures using the similar method. The contact of REZ of cranial nerve with surrounding artery is demonstrated in 31.6% of trigeminal nerves and in 22.5% of facial nerves. These results indicate that the contact of REZ of cranial nerve with surrounding artery is not rare in healthy subjects, though causing TN and HFS in particular patients. In this context, we discussed the difference between the contact which is asymptomatic and the compression which is symptomatic. (author)

    Full Text Available Abstract Background and object There was no Chinese questionnaire to evaluate the health-related quality of life (HRQoL in patients with hemifacial spasm (HFS. In this study, we aimed to validate a new disease-specific HRQoL scale for HFS (HFS-36 in Chinese version, and compared it to SF-36, a generic HRQoL scale. Patients and Methods The HFS-36 Chinese version was modified from English version of HFS-30, including subscales of mobility, activities of daily living (ADL, emotional well-being, stigma, social support, cognition, bodily discomfort, and communication. All the items were scored on the 5-point scales, ranging from 0(never to 4(always. Patients with HFS were asked to answer HFS-36 and SF-36 questionnaires on the same day before and 6-8 weeks after Botulinum toxin (BTX injections, respectively. The reliability and validity of HFS-36 scale were evaluated statistically. Results Totally, 103 patients (68 females; 35 males were recruited in this study, with a mean age of 57.6 ± 11.5 years and a mean duration of HFS for 7.6 ± 5.8 years. The intra-class correlation (ICC and Cronbach's α were over 0.7 in the majority of items. HFS-36 showed a good correlation to HFS severity before BTX treatment and a significant improvement of subscale scoring after BTX treatment. HFS-36 also had a significant correlation to the mental health of SF-36. Conclusions The Chinese version of HFS-36 demonstrated a good reliability and validity in subscales of motility, ADL, emotion well-being, stigma and bodily discomfort. The HRQoL was significantly improved after BTX treatment assessed by HFS-36 or SF-36. Compared to SF-36, HFS-36 scale was more sensitive and specific to evaluate the HRQoL in HFS.

    A controlled, blind study was conducted to define the initial inflammatory response and lung damage associated with the death of precardiac stages of Dirofilaria immitis in cats as compared to adult heartworm infections and normal cats. Three groups of six cats each were used: UU: uninfected untreated controls; PreS I: infected with 100 D. immitis L3 by subcutaneous injection and treated topically with selamectin 32 and 2 days pre-infection and once monthly for 8 months); IU: infected with 100 D. immitis L3 and left untreated. Peripheral blood, serum, bronchial lavage, and thoracic radiographic images were collected from all cats on Days 0, 70, 110, 168, and 240. CT images were acquired on Days 0, 110, and 240. Cats were euthanized, and necropsies were conducted on Day 240 to determine the presence of heartworms. Bronchial rings were collected for in vitro reactivity. Lung, heart, brain, kidney, and liver tissues were collected for histopathology. Results were compared for changes within each group. Pearson and Spearman correlations were performed for association between histologic, radiographic, serologic, hematologic and bronchoalveolar lavage (BAL) results. Infected cats treated with selamectin did not develop radiographically evident changes throughout the study, were heartworm antibody negative, and were free of adult heartworms and worm fragments at necropsy. Histologic lung scores and CT analysis were not significantly different between PreS I cats and UU controls. Subtle alveolar myofibrosis was noted in isolated areas of several PreS I cats and an eosinophilic BAL cytology was noted on Days 75 and 120. Bronchial ring reactivity was blunted in IU cats but was normal in PreS I and UU cats. The IU cats became antibody positive, and five cats developed adult heartworms. All cats with heartworms were antigen positive at one time point; but one cat was antibody positive, antigen negative, with viable adult females at necropsy. The CT revealed early involvement

    Full Text Available Functional Electrical Stimulation (FES has been used extensively over several decades to reverse muscle atrophy during rehabilitation for spinal cord injury patients. The benefits of the technology are being expanded into other areas, and FES has been recently utilized for injury rehabilitation and performance enhancement in horses. Six retired horses (age from 10 to 17 yrs that had been previously used mainly for dressage riding were selected for this study. Clinical evaluation found epaxial muscle spasms in all horses with minimal to no pelvic extension when manually palpated. FES treatments were performed on the sacral/lumbar region 3 times per week for a period of 8 weeks, obtaining a total of 22 treatments per horse. The Modified Ashworth Scale for grading muscle spasms found a one grade improvement after approximately four FES treatments, indicating improved functional movement of the sacral/lumbar region, supporting the evidence by clinical palpations that a reduction in epaxial muscle spasms occurred. Skeletal muscle biopsies Pre and Post FES treatments were obtained from the longissimus lumborum muscle. Cryosections were stained with a Hemotoxylin-Eosin (H-E, and nicotinamide adenine dinucleotide tetrazolium reductase reaction (NADH-TR. The eventual size change of the muscle fibers were evaluated by morphometry in the H-E and NADH-TR stained cryosections, while in the NADH-TR slides the histochemical density and distribution of mitochondria were also determined. The main results of the morphometric analyses were: 1 As expected for the type of FES treatment used in this study, only a couple of horses showed significant increases in mean muscle fiber size when Pre- vs Post-FES biopsies were compared; 2 In the older horses, there were sparse (or many in one horse very atrophic and angulated muscle fibers in both Pre- and Post-FES samples, whose attributes and distribution suggests that they were denervated due to a distal neuropathy; 3 The

    Full Text Available The purpose of this study was to determine the clinical significance of changes in the plasma  adiponectin  concentration  in  patients  with  bronchial  asthma  and  to  test  the association between the single nucleotide polymorphisms (SNPs rs2241766 and rs1501299 in the ADIPOQ gene and bronchial asthma in the Chinese Li population.We selected 120 cases and 120 controls, and plasma adiponectin, interleukin (IL-6, and tumor  necrosis  factor-alpha  (TNF-α  levels  were  measured  by  enzyme-linked immunosorbent assay (ELISA. In addition, we genotyped two tag single nucleotide polymorphisms (tSNPs and evaluated their association with bronchial asthma using the χ2 test and genetic model analysis.Compared to controls, patients with acute exacerbation of bronchial asthma showedsignificantly lower adiponectin and significantly higher IL-6 and TNF-α levels (p<0.01. Apositive association was found between the rs1501299 SNP and acute exacerbation (OR =1.62; 95% CI= 1.08-2.43; p= 0.019.The inverse correlation between the plasma adiponectin concentration and asthma exacerbation indicates that adiponectin may play a protective role in the pathogenesis of asthma. Meanwhile, our findings suggest that ADIPOQ polymorphisms influence the risk of developing bronchial asthma in Chinese Li population.

    Objective: Traditional method of closing bronchial stumps after lobectomy was whole layer suture by hand or by stapler. Little is known about the ligated bronchial stump following lobectomy. To evaluate the characteristics of ligation method for closing bronchial stumps. Methods: In this study 90 lobectomies on 15 mongrel dogs and 75 bronchial stump models on fresh cadaver bronchus were performed. Multivariables comparison experimental studies were made on the results of three different closing methods: simple ligation,manual suture and stapling. Results: In the ligation group, the operation time was significantly shortened (P<0.01). The depth of stump cavity between ligation group and suture group was of no difference significantly (P>0.05). The resistance against intrabronchial pressure was greater in the ligation group than in the suture group (P<0.01). Pathological studies illustrated earlier healing of mucosal membrane with milder inflammatory reactions.In clinical practice, 121 lobectomies were successfully performed with simple ligation of the stumps.Conclusion: Simple ligation is a safe, reliable, simple, and applicable method for closing bronchial stump following lobectomies.

    , associated with a high rate of rhinitis symptoms and hay fever. In addition to bronchial asthma, prevalence of allergic diseases in a sample of Taif citizens assessed by an original Arabic questionnaire (phase I evidenced a high prevalence of allergic diseases as Urticaria, allergic rhinitis with or without other co-morbidities, and atopic dermatitis. Effect of high altitude on bronchial asthma is controversial; at high altitudes, the concentrations of the allergens are reduced due to the reduced amounts of vegetation, animal populations and human influences, high UV light exposure and low humidity could be contributing factors to the benefits of high altitude other than allergen avoidance. On the contrary, Lower altitudes have significant beneficial effects for bronchial asthma patients but lessen with increasing altitudes; the mountain climate can modify respiratory function and bronchial responsiveness of asthmatic subjects. Hypoxia, hyperventilation of cold and dry air and physical exertion may worsen asthma or enhance bronchial hyper-responsiveness while a reduction in pollen and pollution may play an important role in reducing bronchial inflammation. Increasing attention has to be paid to the potential of urban air toxics to exacerbate asthma. Continued emphasis on the identification of strategies for reducing levels of urban air pollutants is warranted to reduce respiratory diseases and other diseases related to pollution. Efforts for reducing the asthma burden must focus on primary prevention to reduce the level of exposure of individuals and populations to common risk factors, particularly tobacco smoke, frequent lower respiratory infections during childhood, and environmental air pollution (indoor, outdoor, and occupational.

    Flap-valve obstruction to expiratory flow (V) in a major bronchus can result from inspissated secretions, blood, or foreign body. During inhalation, increasing airway caliber preserves inspired V past the obstruction; during exhalation, decreasing airway diameter causes airflow obstruction and even frank gas trapping. We reasoned that the resultant sequential, biphasic exhalation of the lungs would be best detected by measuring exhaled V versus time. Accordingly, we designed an airway obstruction element in a mechanical lung model to examine flap-valve bronchial obstruction. A mechanical lung simulator was ventilated with a pressure-limited flow generator, where f = 10/min, tidal volume = 850 mL, and respiratory compliance = 40 mL/cm H2O. Airway V (pneumotachometer) and pressure (P) were digitally sampled for 1 min. Then, the circumference of the diaphragm in a respiratory one-way valve was trimmed to generate unidirectional resistance to expiratory V. Measurement sequences were repeated after this flap-valve was interposed in the right "main-stem bronchus." Integration of airway V versus time generated changes in lung volume. During flap-valve obstruction of the right bronchus, the V-time plot revealed preservation of peak expired flow from the normal lung, followed by retarded and decreased flow from the obstructed right lung. Gas trapping of the obstructed lung occurred during conditions of decreased expiratory time and increased expiratory resistance. Airway P could not differentiate between bronchial and tracheal flap-valve obstruction because P decreased abruptly in both conditions. The flow-volume loop displayed less distinctive changes than the flow-time plot, in part because the flow-volume loop was data (flow) plotted against its time integral (volume), with loss of temporal data. In this mechanical lung model, we conclude that bronchial flap-valve obstruction was best detected by the flow-time plot, which could measure the sequential emptying of the

  10. Cystic fibrosis bronchial epithelial cells are lipointoxicated by membrane palmitate accumulation.

    Directory of Open Access Journals (Sweden)

    Laurie-Anne Payet

    Full Text Available The F508del-CFTR mutation, responsible for Cystic Fibrosis (CF, leads to the retention of the protein in the endoplasmic reticulum (ER. The mistrafficking of this mutant form can be corrected by pharmacological chaperones, but these molecules showed limitations in clinical trials. We therefore hypothesized that important factors in CF patients may have not been considered in the in vitro assays. CF has also been associated with an altered lipid homeostasis, i. e. a decrease in polyunsaturated fatty acid levels in plasma and tissues. However, the precise fatty acyl content of membrane phospholipids from human CF bronchial epithelial cells had not been studied to date. Since the saturation level of phospholipids can modulate crucial membrane properties, with potential impacts on membrane protein folding/trafficking, we analyzed this parameter for freshly isolated bronchial epithelial cells from CF patients. Interestingly, we could show that Palmitate, a saturated fatty acid, accumulates within Phosphatidylcholine (PC in CF freshly isolated cells, in a process that could result from hypoxia. The observed PC pattern can be recapitulated in the CFBE41o(- cell line by incubation with 100 µM Palmitate. At this concentration, Palmitate induces an ER stress, impacts calcium homeostasis and leads to a decrease in the activity of the corrected F508del-CFTR. Overall, these data suggest that bronchial epithelial cells are lipointoxicated by hypoxia-related Palmitate accumulation in CF patients. We propose that this phenomenon could be an important bottleneck for F508del-CFTR trafficking correction by pharmacological agents in clinical trials.

    Introduction: Polymorphonuclear neutrophil leukocytes (PMNL) have an important defensive role against various microorganisms and other agents, but by liberating various substances, first of all the superoxide anion (O 2¯), they can damage the bronchial mucosa and influence the development of bronchial inflammation which is the fundamental of bronchial hyperreactivity (BHR). Objective: to show the role of the PMNL for development and level of BHR in patients with chronic obstructive pulmonary disease (COPD). Material and methods: We observed 160 patients with COPD treated in Clinic for Pulmonary Diseases and TB “Podhrastovi” Sarajevo during three years :from 2012 to 2014. They were divided into groups and subgroups according to the first registration of BHR in the course of illness and to the number of exacerbations of the disease in one year. The number of blood PMNL was measured in a stable state of disease at the begging and at the end of investigation. Results: The number of blood PMNL was significantly greater in patients with 3 or more exacerbations per one year (p <0.01). Patients with BHR had significantly greater number blood PMNL than patients without BHR (p< 0.05). Patients with 3 exacerbations per year had a statistically significant increase of number of PMNL between first and last examination (p<0.01). Conclusion: There is statistically significant correlation between the number of blood PMNL and the level of BHR in COPD, but future examination need to be done to determine real role and mode of action of PMNL for these processes.

    Full Text Available The research goal was to formulate and substantiate the hypothesis explaining support for an expiratory air flow in case of pulmonary emphysema. The research method consisted in comparing the mechanical properties of lungs in practically healthy individuals (37 individuals, mean age – (30.4 ± 1.7 y.o. and COPD patients with pronounced lung emphysema (30 patients, mean age – (52.1 ± 2.3 y.o. as well as those of isolated normal lungs (n = 14 and isolated lungs of patients who died of COPD (n = 5. Pulmo-nary mechanics was studied via the simultaneous measurement of transpulmonary pressure and lung ven-tilation volume. General lung hysteresis and elastic lung hysteresis were calculated. The mechanical properties of isolated lungs were studied using passive ventilation under the Donders bell. The air flow was interrupted in order to measure alveolar pressure and develop an elastic lung hysteresis curve. Pres-sure in the Donders bell was changed by means of a special pump in automatic and manual modes. The research has not revealed any fundamental differences between the mechanical properties of the normal and emphysematous lungs. A minimum increase in the pressure inside the Donders bell over atmospheric pressure used to stop air ejection in both normal and the emphysematous lungs as the result of flap-valve bronchial obstruction. In living beings, air is ejected from lungs with an increase in pressure under the conditions of forced expiration. Pressure increases up to (38.6 ± 2.71 cm H2O in healthy individuals and up to (20.5 ± 1.86 cm H2O in COPD patients. Probably, an expiratory air flow is supported by active expiratory bronchial dilatation that counteracts flap-valve bronchial obstruction. The hypothesis is based on the confirmed ability of the lungs to perform inspiratory actions (in addition to the action of respiratory muscles and the theory of mechanical lung activity.

    Exposure to ozone has been associated with airway inflammation, oxidative stress, and bronchial hyperresponsiveness. The goal of this study was to examine whether these adverse effects of ozone could be prevented or reversed by hydrogen sulfide (H2S) as a reducing agent. The H2S donor sodium (NaHS) (2 mg/kg) or vehicle (PBS) was intraperitoneally injected into mice 1 hour before and after 3-hour ozone (2.5 ppm) or air exposure, and the mice were studied 24 hours later. Preventive and therapeutic treatment with NaHS reduced the ozone-induced increases in the total cells, including neutrophils and macrophages; this treatment also reduced levels of cytokines, including TNF-α, chemokine (C-X-C motif) ligand 1, IL-6, and IL-1β levels in bronchial alveolar lavage fluid; inhibited bronchial hyperresponsiveness; and attenuated ozone-induced increases in total malondialdehyde in bronchoalveolar lavage fluid and decreases in the ratio of reduced glutathione/oxidized glutathione in the lung. Ozone exposure led to decreases in the H2S production rate and in mRNA and protein levels of cystathionine-β-synthetase and cystathionine-γ-lyase in the lung. These effects were prevented and reversed by NaHS treatment. Furthermore, NaHS prevented and reversed the phosphorylation of p38 mitogen-activated protein kinase and heat shock protein 27. H2S may have preventive and therapeutic value in the treatment of airway diseases that have an oxidative stress basis.

  14. Barrier disrupting effects of alternaria alternata extract on bronchial epithelium from asthmatic donors.

    Marina S Leino

    Full Text Available Sensitization and exposure to the allergenic fungus Alternaria alternata has been associated with increased risk of asthma and asthma exacerbations. The first cells to encounter inhaled allergens are epithelial cells at the airway mucosal surface. Epithelial barrier function has previously been reported to be defective in asthma. This study investigated the contribution of proteases from Alternaria alternata on epithelial barrier function and inflammatory responses and compared responses of in vitro cultures of differentiated bronchial epithelial cells derived from severely asthmatic donors with those from non-asthmatic controls. Polarised 16HBE cells or air-liquid interface (ALI bronchial epithelial cultures from non-asthmatic or severe asthmatic donors were challenged apically with extracts of Alternaria and changes in inflammatory cytokine release and transepithelial electrical resistance (TER were measured. Protease activity in Alternaria extracts was characterised and the effect of selectively inhibiting protease activity on epithelial responses was examined using protease inhibitors and heat-treatment. In 16HBE cells, Alternaria extracts stimulated release of IL-8 and TNFα, with concomitant reduction in TER; these effects were prevented by heat-treatment of the extracts. Examination of the effects of protease inhibitors suggested that serine proteases were the predominant class of proteases mediating these effects. ALI cultures from asthmatic donors exhibited a reduced IL-8 response to Alternaria relative to those from healthy controls, while neither responded with increased thymic stromal lymphopoietin (TSLP release. Only cultures from asthmatic donors were susceptible to the barrier-weakening effects of Alternaria. Therefore, the bronchial epithelium of severely asthmatic individuals may be more susceptible to the deleterious effects of Alternaria.

    Full Text Available Background: There are many reports on the association between anthracosis and tuberculosis. This study focuses on bronchial anthracosis and associated diseases in the province of South Khorasan-Iran. Methods: This case-series study is performed on patients referred to the Vali-e-Asre Hospital (South Khorasan-Iran for bronchoscopic evaluations during the period of 2009-2012. Written informed consents were obtained prior to bronchoscopic evaluations. The criterion for diagnosis of bronchial anthracosis was black pigmentation on direct observation of bronchus. Bronchial anthracosis was classified into simple (without deformity or complicated (with deformity. Pulmonary tuberculosis (TB was diagnosed either by acid fast staining and culture of liquid samples, or histopathology examination of biopsy. Spirometry was performed to determine the obstructive or restrictive pattern. Results: Among 279 patients who underwent bronchoscopic evaluations, 89 patients, including 34 males (38.2% and 55 (61.79% females, were diagnosed with anthracosis. Simple and complicated anthracosis were observed in 42 (48.2% and 47 (52.8% cases respectively. Mean age of patients was 72.23±9.65 years. There were 43 (48.3% cases of tuberculosis (28 cases with complicated and 15 cases with simple anthracosis (P=0.021. Chest X-ray showed consolidation/infiltration, reticular/fibrotic, and mass/nodule/hilar prominence in 57 (64%, 26 (29.21% and 6 (6.74% cases, respectively. Bronchitis was reported in 42 (%59.15 out of 79 patients whose biopsy samples were taken. Spirometric patterns were obstructive, restrictive, upper airway obstruction, and normal in 45 (50.56%, 32 (35.95%, 2 (2.24%, and 10 (11.23% patients respectively. Conclusion: Tuberculosis is the most frequent disease associated with anthracosis in South Khorasan province. Consequently, patients with anthracosis must be carefully evaluated for tuberculosis.

    Clinical data and experimental studies suggest that bronchial epithelium could serve as a portal of entry for invasive fungal infections. We therefore analyzed the interactions between molds and the bronchial/bronchiolar epithelium at the early steps after inhalation. We developed invasive aspergillosis (Aspergillus fumigatus) and mucormycosis (Lichtheimia corymbifera) murine models that mimic the main clinical risk factors for these infections. Histopathology studies were completed with a specific computer-assisted morphometric method to quantify bronchial and alveolar spores and with transmission electron microscopy. Morphometric analysis revealed a higher number of bronchial/bronchiolar spores for A. fumigatus than L. corymbifera. The bronchial/bronchiolar spores decreased between 1 and 18 hours after inoculation for both fungi, except in corticosteroid-treated mice infected with A. fumigatus, suggesting an effect of cortisone on bronchial spore clearance. No increase in the number of spores of any species was observed over time at the basal pole of the epithelium, suggesting the lack of transepithelial crossing. Transmission electron microscopy did not show spore internalization by bronchial epithelial cells. Instead, spores were phagocytized by mononuclear cells on the apical pole of epithelial cells. Early epithelial internalization of fungal spores in vivo cannot explain the bronchial/bronchiolar epithelium invasion observed in some invasive mold infections. The bioimaging approach provides a useful means to accurately enumerate and localize the fungal spores in the pulmonary tissues.

    Full Text Available The local immunoreactivity of C-reactive protein (CRP was studied in a heterotopic porcine model of posttranplant obliterative bronchiolitis (OB. Bronchial allografts and control autografts were examined serially 2–28 days after subcutaneous transplantation. The autografts stayed patent. In the allografts, proliferation of inflammatory cells (P<.0001 and fibroblasts (P=.02 resulted in occlusion of the bronchial lumens (P<.01. Influx of CD4+ (P<.001 and CD8+ (P<.0001 cells demonstrated allograft immune response. CRP positivity simultaneously increased in the bronchial walls (P<.01, in macrophages, myofibroblasts, and endothelial cells. Local CRP was predictive of features characteristic of OB (R=0.456–0.879, P< .05−P<.0001. Early obliterative lesions also showed CRP positivity, but not mature, collagen-rich obliterative plugs (P<.05. During OB development, CRP is localized in inflammatory cells, myofibroblasts and endothelial cells probably as a part of the local inflammatory response.

    On the model of chronic obstructive pulmonary disease, the effect of therapy with low-molecular-weight peptides on restructuring and functional activity of bronchial epithelium for restoring the immune and barrier function of the lungs and prevention of inflammatory process progression was studied. Chronic obstructive pulmonary disease was modeled in rats by 60-day intermittent exposure to NO2. Administration of tetrapeptide Bronchogen for 1 month eliminates symptoms of remodeling of the bronchial epithelium and lung tissue typical of chronic obstructive pulmonary disease (goblet cell hyperplasia, squamous metaplasia, lymphocytic infiltration and emphysema, and restoration of ciliated cells). Enhanced production of secretory IgA, a local immunity marker, attested to normalization of functional activity of bronchial epithelium, while normalization of cell composition and profile of proinflammatory cytokines in the bronchoalveolar space reflected reduction of neutrophilic inflammation.

    We discuss here three recent applications of high technology in pulmonary medicine. GeneXpert has considerably improved the diagnosis of active tuberculosis. However, the test has also its limits so that clinical assessment, radiology, and sputum microscopy remain fundamental. Treatment of severe emphysema by lung volume reduction is no longer confined to surgical approach, but is now possible by bronchoscopy. Implantation of Nitinol coils in the most diseased parts of the emphysematous lung is a promising technique. Finally, several clinical trials on bronchial thermoplasty have been reported for intractable asthma. The recent publication of the long term effects of this technique is the occasion to update on this matter.

    Full Text Available Bronchial artery aneurysm (BAA is a rare clinical entity. A case of intrapulmonary BAA associated with previous bronchotomy at the same site is described. A 22-year-old woman, who had undergone bronchotomy of the intermediate bronchus for the removal of a foreign body four years previously, presented with recurrent hemoptysis. Because of an increased risk for spinal cord ischemia, she immediately underwent lung resection rather than therapeutic embolization. The incidental finding of a BAA of any cause cannot be assumed to be stable, and immediate management should be undertaken regardless of the presence or absence of symptoms.

    The value of determining the slope of the histamine dose-response curve, in addition to the histamine provocation concentration producing a 20% reduction in FEV1 (PC20-FEV1), was assessed by analysis of histamine dose-response curves in 40 patients selected as having a wide range of increased non-specific bronchial responsiveness to inhaled histamine. The histamine dose-response curves were found to be fit the linear curve (dose v response, mean r2 = 0.97) better than the logarithmic curve (l...

    Bronchial brachytherapy treatments are affected by movement (breathing, coughing, patient discomfort, etc ...) of the probe lodged in the trachea. From the CT images, this movement results in an uncertain trajectory of the probe according to the reconstruction of the catheter is performed. To establish whether this influence has important implications for the location and distance of the section of bronchus treated, is the goal of this work. Other circumstances, such as inaccuracy in the determination of the probe or the delimitation of volumes, increase the uncertainty in the record that the treatment should be pursued.

    We report successful Y90-radioembolization of the lung applying Y90-resin microspheres via the bronchial artery in two patients with diffuse colorectal and renal cancer metastases, respectively. The deposition of radioactive Y90-resin-microspheres was technically feasible and resulted in a reasonable absorbed dose in the tumors. However, open questions remain regarding dosimetry and safe dose exposure to the lung. The technique warrants thorough investigation before clinical use. A Phase I trial to evaluate safety and preliminary efficacy is under preparation.

    Airway compression is a common problem in children with certain forms of congenital heart disease. Although various surgical approaches are available to overcome this form of airway obstruction, internal stenting is necessary in a minority of patients. It can be difficult to assess the success of stenting at the time of the procedure, and the interval to successful extubation is usually used as an outcome measure. Measurement of relevant parameters of respiratory physiology with flow-volume and volume-pressure loops permits immediate quantitative assessment of the adequacy of stenting. A 3-month-old infant who underwent bronchial stenting and physiological assessment at the time of the procedure is described. (orig.)

    Morphometric analysis of airways was performed in autopsied lungs from four patients with pulmonary emphysema (PE) followed by bronchial-asthma (BA)-like attacks (Group PE+BA) (four males, 72 +/- 9 yr). The results were compared with those from five pulmonary emphysema patients (Group PE) (five males, age 71 +/- 4 hr), three patients with bronchial asthma (Group BA) (one female and two males, age 65 +/- 7 yr), and four control subjects with no pulmonary diseases (Group Cont) (one female, three males, age 64 +/- 4 yr). The proportion of gland area to bronchial wall (gland%), ratio of goblet-cell occupancy to the total epithelial layer (goblet%), thickness of the basement membrane, amount of intraluminal mucus (mucus occupying ratio; MOR%), and number of various cell types per square millimeter in airway walls in a section 4 microns thick were measured in central (3 to 8 mm diameter) and peripheral airways (2 mm or less diameter). Gland% for the PE+BA group was significantly greater than that for the Cont group, whereas it did not differ significantly from that of the PE or BA groups. Goblet% and thickness of the basement membrane in central and/or peripheral airways in Group PE+BA were significantly greater than those in Group Cont, whereas those in Group PE were similar to those in Group Cont. Although not statistically significant, MOR% in central and peripheral airways from Group PE+BA showed a similar value to that in Group BA, whereas MOR% in Group PE was the same as that in Group Cont. The eosinophil number in peripheral airways walls in Group PE+BA showed a similar value to that in Group BA, which was significantly greater than in Group Cont. Other cells (macrophages, lymphocytes, and neutrophils) showed similar values among Groups PE+BA, PE, and BA. The number of eosinophils in central and/or peripheral airways correlated significantly with both goblet% and BMT, whereas other cells did not. These findings indicate that the airways of Group PE+BA are

An interview schedule was developed to evaluate the usefulness of the manual. The validity and reliability of both these instruments were established. Five hundred and twenty three diagnosed patients of bronchial asthma (260 in the study group to whom the self care manual was given and 263 controls to whom no specific instructions were given were included in the study. Emotions like ′tension′, ′excessive laughter′, ′sadness′, ′happiness′ and ′anger′ etc. that triggered the symptoms were studied. The effect of self care manual on other emotions (FNx01a total of 8 items like ′anxiety due to the disease′, ′tension of taking medicine′ and ′fear of death′ etc. was also studied. Both groups were followed up at 2 weeks, 6 months and 1 year while the same interview schedule was administered on each visit. It was observed that the emotion scores decreased significantly in both the groups (8.08±5.5, 5.89±4.88, 1.44±4.63 and 1.19±4.01 in the study patients, whereas 8.50±6.30, 7.88±6.21, 7.35±6.03 and 5.97±5.81 in the controls at 0 weeks, 2 weeks, 6 months and 1 year respectively. The emotion scores were significantly less in the study group as compared to controls (unpaired ′t′ = 3.57, 8.52 and 7.67 at 2 weeks, 6 months and 1 year respectively (p< 0.001 Multiple logistic regression analysis showed that the odds ratio of study group patients showing significant improvement in emotion scores was 3.34 (95% CI, 1.78-6.25 and 4.26 (95% CI, 2.34-7.63 at 6 months and 1 year respectively as compared to controls. We concluded that patient education (self care manual in the form of a booklet made significant improvement in the emotions in patients with bronchial asthma.

    Polymerase chain reaction (PCR) is a sensitive method for detection of Aspergillus DNA in bronchoalveolar lavage fluid, but it has not yet been able to distinguish infection from contamination. We have established a technique to quantify Aspergillus DNA using a real-time PCR method to resolve this problem, and we report herein a successful application of real-time PCR to diagnose invasive pulmonary aspergillosis by comparing the amount of Aspergillus DNA in bronchial lavage fluid from an affected area to that from an unaffected area. This novel tool will provide rapid, sensitive, and specific diagnosis of pulmonary aspergillosis.

  13. MicroRNA-221 modulates RSV replication in human bronchial epithelium by targeting NGF expression.

    Sreekumar Othumpangat

    Full Text Available BACKGROUND: Early-life infection by respiratory syncytial virus (RSV is associated with aberrant expression of the prototypical neurotrophin nerve growth factor (NGF and its cognate receptors in human bronchial epithelium. However, the chain of events leading to this outcome, and its functional implications for the progression of the viral infection, has not been elucidated. This study sought to test the hypothesis that RSV infection modulates neurotrophic pathways in human airways by silencing the expression of specific microRNAs (miRNAs, and that this effect favors viral growth by interfering with programmed death of infected cells. METHODOLOGY: Human bronchial epithelial cells infected with green fluorescent protein-expressing RSV (rgRSV were screened with multiplex qPCR arrays, and miRNAs significantly affected by the virus were analyzed for homology with mRNAs encoding neurotrophic factors or receptors. Mimic sequences of selected miRNAs were transfected into non-infected bronchial cells to confirm the role of each of them in regulating neurotrophins expression at the gene and protein level, and to study their influence on cell cycle and viral replication. PRINCIPAL FINDINGS: RSV caused downregulation of 24 miRNAs and upregulation of 2 (p<0.01. Homology analysis of microarray data revealed that 6 of those miRNAs exhibited a high degree of complementarity to NGF and/or one of its cognate receptors TrKA and p75(NTR. Among the selected miRNAs, miR-221 was significantly downregulated by RSV and its transfection in bronchial epithelial cells maximally inhibited gene and protein expression of NGF and TrKA, increased apoptotic cell death, and reduced viral replication and infectivity. CONCLUSIONS/SIGNIFICANCE: Our data suggest that RSV upregulates the NGF-TrKA axis in human airways by silencing miR-221 expression, and this favors viral replication by interfering with the apoptotic death of infected cells. Consequently, the targeted delivery of

    Intermittent monitoring of abnormal muscle response (iAMR) has been reported to be useful for improving the surgical outcome of microvascular decompression (MVD) for hemifacial spasm (HFS). However, iAMR has not elucidated the relationship between AMR change and the corresponding surgical procedure, or the pathogenesis of AMR and HFS. The purpose of this study is to clarify the usefulness of continuous AMR monitoring (cAMR) for improving the surgical results of MVD and for understanding the relationship between AMR change and corresponding surgical procedure, and the pathogenesis of AMR and HFS. Fifty consecutive patients with HFS treated by MVD under cAMR monitoring, which continuously records AMR every minute throughout the surgical period, were retrospectively analyzed. The patients were assessed for the presence of HFS 1 week after the surgery and at final follow-up. Forty-six patients showed the complete disappearance of HFS. In 32, AMR disappeared abruptly and simultaneously with decompression of an offending vessel. AMR showed dynamic and various changes including temporary disappearance, or sudden, gradual, or componential disappearance before and during the decompression procedure, and even during the dural and skin closure after the initial decompression procedure. Facial spasm remained in four patients despite permanent AMR disappearance. cAMR monitoring improves the outcome of MVD. Although the main cause of HFS and AMR is vascular compression at the facial nerve, hyperexcitability of the facial nucleus is also involved in the pathogenesis of HFS and AMR. The proportional involvement of these causes differs between patients.

  17. Tracheal dysplasia precedes bronchial dysplasia in mouse model of N-nitroso trischloroethylurea induced squamous cell lung cancer.

    Directory of Open Access Journals (Sweden)

    Full Text Available Squamous cell lung cancer (SCC is the second leading cause of lung cancer death in the US and has a 5-year survival rate of only 16%. Histological changes in the bronchial epithelium termed dysplasia are precursors to invasive SCC. However, the cellular mechanisms that cause dysplasia are unknown. To fill this knowledge gap, we used topical application of N-nitroso-tris chloroethylurea (NTCU for 32 weeks to induce squamous dysplasia and SCC in mice. At 32 weeks the predominant cell type in the dysplastic airways was Keratin (K 5 and K14 expressing basal cells. Notably, basal cells are extremely rare in the normal mouse bronchial epithelium but are abundant in the trachea. We therefore evaluated time-dependent changes in tracheal and bronchial histopathology after NTCU exposure (4, 8, 12, 16, 25 and 32 weeks. We show that tracheal dysplasia occurs significantly earlier than that of the bronchial epithelium (12 weeks vs. 25 weeks. This was associated with increased numbers of K5+/K14+ tracheal basal cells and a complete loss of secretory (Club cell secretory protein expressing CCSP+ and ciliated cells. TUNEL staining of NTCU treated tissues confirmed that the loss of CCSP+ and ciliated cells was not due to apoptosis. However, mitotic index (measured by bromodeoxyuridine incorporation showed that NTCU treatment increased proliferation of K5+ basal cells in the trachea, and altered bronchial mitotic population from CCSP+ to K5+ basal cells. Thus, we demonstrate that NTCU-induced lung epithelial dysplasia starts in the tracheal epithelium, and is followed by basal cell metaplasia of the bronchial epithelium. This analysis extends our knowledge of the NTCU-SCC model by defining the early changes in epithelial cell phenotypes in distinct airway locations, and this may assist in identifying new targets for future chemoprevention studies.

    Exposure to elevated concentrations of ozone, a common air pollutant, has been associated with numerous adverse health effects. We have previously reported the time-course of ozone-induced airway inflammation, demonstrating an early up-regulation of vascular endothelial adhesion molecules in bronchial mucosa at 1.5 hours, followed by a neutrophilic infiltration 6 hours after exposure to 0.2 ppm ozone. We hypothesized that the neutrophilic infiltration in the bronchial mucosa would reflect an early increase in bronchial epithelial expression of redox-sensitive transcription factors and kinases regulating neutrophil chemoattractant expression. To test this hypothesis, endobronchial biopsies were obtained from healthy human subjects (n = 11) 1.5 hours after 0.2 ppm of ozone and filtered air exposures (lasting for 2 hours) and stained for mitogen-activated protein kinases (MAPKs), transcription factors, and neutrophil chemoattractants. Total epithelial staining was quantified, as well as the extent of nuclear translocation. Contrary to expectation, ozone significantly suppressed total and nuclear expression of nuclear factor kappaB (NFkappaB) in bronchial epithelial cells (p = 0.02 and p = 0.003 respectively). Similarly, the total staining for phosphorylated C-jun was suppressed (p = 0.021). Expression of interleukin 8 (IL-8) in the bronchial epithelium was likewise decreased after ozone (p = 0.018), while GRO-alpha, ENA-78, C-fos, p-p38, p-JNK, and p-ERK stainings were unchanged. These data suggest that the redox-sensitive NFkappaB and activator protein 1 (AP-1) pathways within the human bronchial epithelium do not seem to be involved in the early inflammatory cell recruitment pathways in healthy subjects exposed to ozone.

    PD25-V50 as a judgement of bronchial provocation test was compared with PD20-FEV1. Both PD25-V50 and PD20-FEV1 showed linear correlation, but PD25-V50 was more sensitive than PD20-FEV1 for the diagnosis of bronchial asthma, and had higher specificity and sensitivity, and lower false-negative and false-positiverate. Moreover PD25-V50 provided the advantages of shorter period of histamine provocation and lower dose of inhaled histamine, so that avoided the side effects of higher dose of histamine.
