    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.

    Thoracic surgery poses a risk for complications in the respiratory system. In particular, for patients with bronchial asthma, we need to care for perioperative complications because it is well known that these patients frequently have respiratory complications after surgery, and they may have bronchial spasms during surgery. If we can get good control of their bronchial asthma, we can usually perform surgery for these patients without limitations. For safe postoperative care, it is desirable that these patients have stable asthma conditions that are well-controlled before surgery, as thoracic surgery requires intrabronchial intubation for anesthesia and sometimes bronchial resection. These stimulations to the bronchus do not provide for good conditions because of the risk of bronchial spasm. Therefore, we should use the same agents that are used to control bronchial asthma if it is already well controlled. If it is not, we have to administer a β₂ stimulator, aminophylline, or steroidal agents for good control. Isoflurane or sevoflurane are effective for the safe control of anesthesia during surgery, and we should use a β₂ stimulator, with or without inhalation, or steroidal agents after surgery. It is important to understand that we can perform thoracic surgery for asthma patients if we can provide perioperative control of bronchial asthma, although these patients still have severe risks.

    Radiologic and manometric findings were correlated in 17 patients with diffuse esophageal spasm (DES). All patients initially had chest pain and/or dysphagia and had a manometric diagnosis of DES. Mean percentage of normal peristalsis manometrically was 46% (range, 20%-80%). Based on radiologic examination, an esophageal motor disorder consistent with DES was diagnosed in 12 of 17 patients, and there was one misinterpretation of achalasia. Radiologic detection was not related significantly to the percentage of peristalsis seen on manometric examination. Mean esophageal wall thickness as measured radiographically in patients with DES was 2.6 mm, compared with 2.5 mm in 17 individuals with normal results of manometry

    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 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.

    In order to evaluate the value of vertebral angiography in assesment of hemifacial spasm, We reviewed retrospectively the vertebral angiography of 28 patients (30 cases) with surgically proved hemifacial spasm but normal CT scans of posterior fossa. There were 9 males and 19 females. Angiography revealed vascular focus of hemifacial spasm located at anterior inferior cerebellar artery , posterior inferior cerebellar artery, and vertebral artery in 19, 9, and 2 cases respectively. Right side was involved in 20 cases. All involved vessels were elongated, tortuous, and dilated. In conclusion, vertebral angiography was valuable in evaluating hemifacial spasm of vascular origin in the posterior fossa

    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.

    Spasm of the near reflex is most often seen on a functional basis in young adults with underlying emotional problems. In particular, when convergence spasm is associated with miosis on attempted lateral gaze, a functional basis for the disorder should be suspected. Patients who experience spasm of the near reflex following trauma commonly follow a benign course with spontaneous resolution of their ocular complaints within 1-2 years. Accommodative spasm, manifested by pseudomyopia, or spasm of convergence, alone, or in combination with miosis, may be found as isolated signs of spasm of the near reflex. We report a patient who continues to demonstrate accommodative spasm 9 years after a motor vehicle accident.

    A 59 years old man was admitted at hospital for recurrent instable angina 1 month after coronary artery bypass surgery. Coronary artery disease started with a transmural antero-septo-apical myocardial infarction without thrombolysis and a percutaneous angioplasty with endo-prothesis on proximal left anterior descendant artery (LAD) is performed Because of recurrent rest angina and subacute stent thrombosis, a coronary artery bypass surgery (CABG) is performed with anastomosis of the left internal thoracic artery on LAD. The patient is admitted for recurrent rest angina one month after CABG. On ECG performed during chest pain, a ST-T segment elevation occurred on inferior leads. Coronary angiography showed no significant stenosis on endo-prothesis and no bypass graft dysfunction. Dipyridamole scintigraphy was realized. 2 minutes after the beginning of Dipyridamole infusion, a ST-T elevation occurred on inferior leads and two marked antero-septal and inferior defects were noticed on myocardial scintigraphy. Images at rest showed a clear improvement in the anterior wall and the inferior wall became normally perfused Patient was treated with anti-spastic drugs and a new coronarography with methyl-ergotamine test was performed inducing chest pain, ST-T elevation on inferior leads and tri-truncular coronary spasm. Patient's treatment was then modified with introduction of Nifedipine. The patient did not experienced new recurrent chest pain and remained totally asymptomatic few months later. (authors)

    In ten patients with infantile spasms, brainstem evoked potentials and MRI examinations were performed to evaluate the brainstem involvement. The result of short latency somatosensory evoked potentials (SSEP) following the right median nerve stimulation revealed abnormal findings including the absence or low amplitudes of the waves below wave P3 and delayed central conduction time in 7 of the ten patients. The result of auditory brainstem responses (ABR) revealed abnormal findings including low amplitudes of wave V, prolonged interpeak latency of waves I-V and absence of the waves below wave IV in 5 of the ten patients. The result of the MRI examinations revealed various degrees of the brainstem atrophy in 6 of the ten patients, all of whom showed abnormal brainstem evoked potentials. The result of this study demonstrates that patients with infantile spasms are frequently associated with brainstem dysfunction and raises the possibility that brainstem atrophy might be a cause of infantile spasms.

    Hemifacial spasm is a neuromuscular movement disorder characterized by brief or persistent involuntary contractions of the muscles innervated by the facial nerve. Its prevalence has been estimated at 11 cases per 100 000 individuals. Among the patients who were operated on by our team, the mean interval from diagnosis to surgery was 8.2 years, and more than half of them learned of the possibility of surgical treatment only through a personal search for information on the condition. These facts motivated us to write this article to raise the awareness of hemifacial spasm and its neurosurgical treatment among physicians who will encounter it. This review article is based on a selective literature search and on our own clinical experience. Hemifacial spasm is usually caused by an artery compressing the facial nerve at the root exit zone of the brainstem. 85-95% of patients obtain moderate or marked relief from local injections of botulinum toxin (BTX), which must be repeated every 3 to 4 months. Alternatively, microvascular decompression has a success rate of about 85%. Local botulinum-toxin injection is a safe and well-tolerated symptomatic treatment for hemifacial spasm. In the long term, however, lasting relief can only be achieved by microvascular decompression, a microsurgical intervention with a relatively low risk and a high success rate.

  20. Cranial computed tomography in infantile spasms

    Howitz, P.; Neergaard, K.; Pedersen, H.

    1990-01-01

    Out of 109 children with infantile spasms (IS), prospectively tested during the years 1976 to 1979 in Denmark, 52 children were examined by cranial computed tomography (CT). The classification of IS into cryptogenic (CR), symptomatic (SY) and doubtful (DO) was done clinically without considering the CT-finding. Sixty per cent of the scannings were abnormal. Only 6/30 (20%) of the children in ACTH treatment were found to develop cerebral atrophy which means that this finding is not an obligatory side-effect of ACTH treatment of children with IS. Normal CT-findings were found in 50% of the CR and 50% of the SY + DO-groups, and could not be used as a prognostic tool for estimating the mental development. This was also the case for children with cerebral atrophy. Abnormal CT-findings (minus atrophy) were highly correlated to the group with clinical symptoms and indicate an extremely unsatisfying long-term mental prognosis. CT-scanning is a valuable tool for the examination of clearing children with infantile spasms. (authors)

    Full Text Available The article highlights the results of the act test based bronchial asthma supervision evaluation among teenagers and defines the interrelation of the objective and subjective asthma supervision parameters. The researchers examined 214 male teenagers aged from 16 to 18, suffering from the bronchial asthma, who were sent to the allergy department to verify the diagnosis. Bronchial asthma supervision evaluation was assisted by the act test. The research has showed that over a half (56% of teenagers, suffering from mild bronchial asthma, mention its un control course, do not receive any adequate pharmacotherapy and are consequently a risk group in terms of the bronchial asthma exacerbation. Act test results correlate with the functional indices (fev1, as well as with the degree of the bronchial hyperresponsiveness, which is one of the markers of an allergic inflammation in the lower respiratory passages.Key words: bronchial asthma supervision, act test, teenagers.

    Although Sir Charles Bell was the first to provide the anatomic basis for the condition that bears his name, in recent years researchers have shown that other European physicians provided earlier clinical descriptions of peripheral cranial nerve 7 palsy. In this article, we describe the history of facial distortion by Greek, Roman, and Persian physicians, culminating in Razi's detailed description in al-Hawi. Razi distinguished facial muscle spasm from paralysis, distinguished central from peripheral lesions, gave the earliest description of loss of forehead wrinkling, and gave the earliest known description of bilateral facial palsy. In doing so, he accurately described the clinical hallmarks of a condition that we recognize as Bell palsy. PMID:21747074

    The PercuSurge system is a distal balloon embolic protection device used for carotid artery stenting (CAS). We performed a retrospective study on the prognosis and clinical effects of spasms induced by the PercuSurge GuardWire system (PercuSurge-induced spasm). We performed CAS in 118 carotid stenoses using the PercuSurge system. Of the 118 procedures, 31 (26.3%) of the patients experienced PercuSurge-induced spasm, and all underwent postoperative follow-up studies by cerebral angiography and antiplatelet treatment. On follow-up angiograms obtained a mean of 5.2 months (range 3-10 months) after CAS, all 31 PercuSurge-induced spasms had disappeared, and no delayed stenosis was found at the sites where the spasms had occurred. No ischemic events due to the spasms occurred during a mean follow-up of 13 months (range 3-32 months). In the hands of physicians experienced in endovascular surgery, CAS using the PercuSurge system is a safe method with which to treat patients with carotid stenosis. Our study demonstrated that PercuSurge-induced spasms had no morphological or clinical adverse effects. (author)

  4. 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.

    It is of value to update radon daughter bronchial dosimetry as new information becomes available. Measurements have now been performed using hollow casts of the human bronchial tree with a larynx to determine convective or turbulent deposition in the upper airways. These measurements allow a more realistic calculation of bronchial deposition by diffusion. Particle diameters of 0.15 and 0.2 μm were used which correspond to the activity median diameters for radon daughters in both environmental and mining atmospheres. The total model incorporates Yeh/Schum bronchial morphometry, deposition of unattached and attached radon daughters, build up and decay of the daughters and mucociliary clearance. The alpha dose to target cells in the bronchial epithelium is calculated for the updated model and compared with previous calculations of bronchial dose

She was diagnosed with spasm of the near reflex. Treatment with injections of botulinum toxin in both medial rectus has temporally resolved the convergence spasm. Near reflex spasm is characterized as miosis, pseudomyopia, and convergent strabismus that lead to diplopia, blurred vision, headache, and variable, progressive, and intermittent esotropia. As the spasm worsens there will be limited ocular versions and ductions simulating a sixth nerve palsy. Botulinum toxin may be effective in some cases.

    2002-03-01

    Spasm of accommodation, creating pseudomyopia, is generally associated with miosis and excess convergence as part of spasm of the near reflex. It may also exist as an isolated entity, usually attributed to psychogenic causes. We present six cases of accommodative spasm associated with closed head injury. All patients were male, ranging in age between 16 and 37 years. The degree of pseudomyopia, defined as the difference between manifest and cycloplegic refraction, was 1.5 to 2 diopters. A 3-year trial of pharmacologically induced cycloplegia in one patient did not lead to reversal of the spasm when the cycloplegia was stopped. All patients required the manifest refraction to see clearly at distance. The pseudomyopia endured for at least 7 years following head trauma. This phenomenon may represent traumatic activation or disinhibition of putative brain stem accommodation centers in young individuals.

    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.

    Infantile spasms (IS) represent a serious epileptic syndrome, called West syndrome (WS) that occurs in the early infantile age. Although several hypotheses and animal models have been proposed to explain the pathogenesis of IS, the pathophysiology of IS has not been elucidated. Recently, we proposed a hypothesis for IS under prenatal stress exposure (also called Zou's hypothesis) by correlating diverse etiologies and prenatal stresses with IS development. This research aims to determine the mechanism through which prenatal stress affects the offspring and establish the potential underlying mechanisms. Pregnant rats were subjected to forced swimming in cold water. Rat pups exposed to prenatal stress were administered with N-methyl-D-aspartate (NMDA). Exposure to prenatal stress sensitized the rats against development of NMDA-induced spasms. However, this phenomenon was altered by administering adrenocorticotropin. Prenatal stress exposure also altered the hormonal levels and neurotransmitter receptor expression of the developing rats as well as influenced the tissue structure of the brain. These findings suggest that maternal stress could alter the level of endogenous glucocorticoid, which is the basis of IS, and cerebral dysplasia, hypoxic-ischemic encephalopathy (HIE), inherited metabolic diseases, and other factors activated this disease in developmental brain.

The examination encompassed esophageal manometry, esophagogastroduodenoscopy, 24-hour pH metry, and an interview using a questionnaire to identify autonomic disorders, and the Mini-Mult test. The patients with primary ES compared to those with ES concurrent with GERD significantly more frequently showed severe pain syndrome (p = 0.009) and a paradoxical dysphagia pattern (p = 0.03); manometry revealed an incoordination in the motility of the entire esophagus (p = 0.001). Comparison of the statistical series of values for contraction amplitude and duration in the distal esophagus found no significant difference in the patients of both groups. Autonomic disturbances were detected in 76.0% of the patients with ES; but the intergroup differences were insignificant. Mental maladaptation was observed in 81.7% of the patients in the absence of intergroup differences. The etiopathogenetic factor of ES is a psychoautonomic response to chronic stress in both primary ES and its concurrence with GERD. The reflux of gastric contents into the esophagus does not appear to be one of the leading causes of ES. In primary ES, esophageal motor function is generally impaired to a much greater extent than that in ES concurrent with GERD. The degree of motor disorders is embodied in the specific clinical features of the disease.

    Many asthma patients seek alternative or adjunctive therapies. One such modality is reflexology, whereby finger pressure is applied to certain parts of the body. The aim of the study was to examine the popular claim that reflexology treatment benefits bronchial asthma. Ten weeks of active...... or simulated (placebo) reflexology given by an experienced reflexologist, were compared in an otherwise blind, controlled trial of 20+20 outpatients with asthma. Objective lung function tests (peak flow morning and evening, and weekly spirometry at the clinic) did not change. Subjective scores (describing...... diaries was carried out. It was accompanied by a significant pattern compatible with subconscious unblinding, in that patients tended to guess which treatment they had been receiving. No evidence was found that reflexology has a specific effect on asthma beyond placebo influence....

    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.

    For evaluation of coronary artery spasm 201 thallium sequential scintigraphy of the myocardium after ergotamine provocation was performed in 10 patients with recurrent angina pectoris at rest and normal exercise ECG. In 9 out of the 10 patients ergotamine administration in the same dosage was repeated during the coronary angiography. A reversible defect in the 201 thallium scintigram representative of regional myocardial ischaemia developed in 9 patients after ergotamine. Only in 4 out of the 9 patients angina pectoris and ST elevation were present at the same time. In all cases coronary spasm after ergotamine was demonstrable in the coronary angiogram; in the 4 patients with ergotamine-induced Prinzmetal angina pectoris it consisted of complete vascular occlusion, in the asymptomatic patients of incomplete vascular narrowing of a higher degree. In all cases the spasm could be relieved by ergotamine antidotes within a few minutes. (orig.) [de

    Intraoperative transesophageal echocardiography (TEE) was performed on a 62-year-old man who underwent abdominal aortic replacement for abdominal aortic aneurysm under general anesthesia combined with epidural anesthesia. Coronary artery spasm occurred after unexpected massive hemorrhage, and TEE showed hypokinesis in the posterior-inferior left ventricular wall. The changes in TEE preceded the ST elevation in the ECG. Bolus infusion of isosorbide dinitrate and continuous infusion of nitroglycerin alleviated these changes. TEE enabled us to detect and evaluate coronary spasm before the appearance of ST changes in ECG.

    Asthma is defined as a chronic inflammatory airway disease in response to a wide variety of provoking stimuli. Characteristic clinical symptoms of asthma are bronchial hyperreactivity, reversible airway obstruction, wheezing and dyspnea. Asthma presents a major public health problem with increasing prevalence rates and severity worldwide. Despite major advances in our understanding of the clinical management of asthmatic patients, it remains a challenging population for anesthesiologists in clinical practice. The anesthesiologist's responsibility starts with the preoperative assessment and evaluation of the pulmonary function. For patients with asthma who currently have no symptoms, the risk of perioperative respiratory complications is extremely low. Therefore, pulmonary function should be optimized preoperatively and airway obstruction should be controlled by using steroids and bronchodilators. Preoperative spirometry is a simple means of assessing presence and severity of airway obstruction as well as the degree of reversibility in response to bronchodilator therapy. An increase of 15% in FEV1 is considered clinically significant. Most asymptomatic persons with asthma can safely undergo general anesthesia with and without endotracheal intubation. Volatile anesthetics are still recommended for general anesthetic techniques. As compared to barbiturates and even ketamine, propofol is considered to be the agent of choice for induction of anesthesia in asthmatics. The use of regional anesthesia does not reduce perioperative respiratory complications in asymptomatic asthmatics, whereas it is advantageous in symptomatic patients. Pregnant asthmatic and parturients undergoing anesthesia are at increased risk, especially if regional anesthetic techniques are not suitable and prostaglandin and its derivates are administered for abortion or operative delivery. Bronchial hyperreactivity associated with asthma is an important risk factor of perioperative bronchospasm. The

    Pelvic floor disorders can present with lower urinary tract symptoms, bowel, sexual dysfunction, and/or pain. Symptoms of pelvic muscle spasm (nonrelaxing pelvic floor or hypertonicity) vary and can be difficult to recognize. This makes diagnosis and management of these disorders challenging. In this article, we review the current evidence on pelvic floor spasm and its association with voiding dysfunction. To distinguish between the different causes of voiding dysfunction, a video urodynamics study and/or electromyography is often required. Conservative measures include patient education, behavioral modifications, lifestyle changes, and pelvic floor rehabilitation/physical therapy. Disease-specific pelvic pain and pain from pelvic floor spasm needs to be differentiated and treated specifically. Trigger point massage and injections relieves pain in some patients. Botulinum toxin A, sacral neuromodulation, and acupuncture has been reported in the management of patients with refractory symptoms. Pelvic floor spasm and associated voiding problems are heterogeneous in their pathogenesis and are therefore often underrecognized and undertreated; it is therefore essential that a therapeutic strategy needs to be personalized to the individual patient's requirements. Therefore, careful evaluation and assessment of individuals using a multidisciplinary team approach including a trained physical therapist/nurse clinician is essential in the management of these patients.

  20. Decompression of the facial nerve in cases of hemifacial spasm

    Directory of Open Access Journals (Sweden)

    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.

  1. Bronchial dosimeter for radon progeny

    Traditionally, assessments of the bronchial dose from radon progeny were carried out by measuring the unattached fraction (f{sub p}) of potential alpha energy concentration (PAEC), the total PAEC, activity median diameters (AMDs) and equilibrium factor, and then using dosimetric lung models. A breakthrough was proposed by Hopke et al. (1990) to use multiple metal wire screens to mimic the deposition properties of radon progeny in the nasal (N) and tracheobronchial (T-B) regions directly. In particular, they were successful in using four layers of 400-mesh wire screens with a face velocity of 12 cm s{sup -1} for the simulation of radon progeny deposition in the T-B region. Oberstedt and Vanmarcke (1995) carried out precise calibrations for the system, and named the system as the 'bronchial dosimeter'. Based on these, Yu and Guan (1998) proposed a portable bronchial dosimeter similar to a normal measurement system for radon progeny or PAEC and consisted of only a single sampler and employed only one 400-mesh wire screen and one filter. However, all these 'bronchial dosimeters' in fact only determined the fraction of potential alpha energy from radon progeny deposited in the T-B region, which required certain assumptions and calculations to further give the final bronchial dose. In the present work, a true 'bronchial dosimeter' was designed, which consisted of three 400-mesh wire screens and a filter. With a face velocity of 11 cm s{sup -1}, the deposition pattern on the wire screens was found to satisfactorily match the variation of the dose conversion factor (in the unit of mSv/WLM) with the size of radon progeny from 1 to 1000 nm. In this way, this bronchial dosimeter directly gave the bronchial dose from the alpha counts recorded on the wire-screens and the filter paper. With the development of this bronchial dosimeter, the present practice of 'dose estimation' from large-scale radon surveys can be replaced by large

    Coronary spasm is abnormal contraction of an epicardial coronary artery resulting in myocardial ischemia. Coronary spasm induces not only depressed myocardial contractility, but also incomplete myocardial relaxation, which leads to elevated ventricular filling pressure. We herein report the case of a 55-year-old woman who had repeated acute heart failure caused by coronary spasm. Acetylcholine provocation test with simultaneous right heart catheterization was useful for the diagnosis of elevated ventricular filling pressure as well as coronary artery spasm. We should add coronary spasm to a differential diagnosis for repeated acute heart failure.

    Hemifacial spasm (HFS) is mostly caused by the compression of the facial nerve by cerebral vessels, but the significance of spasm severity remains unclear. We investigated the clinical significance of spasm severity in patients with HFS who underwent microvascular decompression (MVD). We enrolled 636 patients with HFS who underwent MVD between May 2010 and December 2013 at Samsung Medical Center (SMC), Seoul, Korea. Subjects were divided into two groups based on spasm severity: severe (SMC grade 3 or 4) and mild (SMC grade 1 or 2). We compared demographic, clinical, and surgical data between these two groups. The severe-spasm group was older and had a longer disease duration at the time of MVD compared to the mild-spasm group. Additionally, hypertension and diabetes mellitus were more common in the severe-spasm group than in the mild-spasm group. Regarding surgical findings, there were more patients with multiple offending vessels and more-severe indentations in the severe-spasm group than in the mild-spasm group. Even though the surgical outcomes did not differ, the incidence of delayed facial palsy after MVD was higher in the severe-spasm group than in the mild-spasm group. Logistic regression analysis showed that severe-spasm was correlated with longer disease duration, hypertension, severe indentation, multiple offending vessels, and delayed facial palsy after MVD. Spasm severity does not predict surgical outcomes, but it can be used as a marker of pathologic compression in MVD for HFS, and be considered as a predictor of delayed facial palsy after MVD.

    To determine the efficacy of the ketogenic diet in controlling epileptic spasms after failing traditional antiepileptic medication therapy. This is a prospective, case-based study of all infants with epileptic spasms who were referred for treatment with the ketogenic diet at our hospital between 2009 and 2012. All subjects continued to have epileptic spasms with evidence of hypsarrhythmia or severe epileptic encephalopathy on electroencephalography despite appropriate medication treatments. The diet efficacy was assessed through clinic visits, phone communications, and electroencephalography. Quality of life improvement was charted based on the caregiver's perspective. Twenty infants (15 males) were included in the study. The mean age at seizure onset was 4.5 months. Age at ketogenic diet initiation was 0.3 to 2.9 years (mean 1.20, standard deviation 0.78). Fifteen patients had epileptic spasms of unknown etiology; three had perinatal hypoxic ischemic encephalopathy, one had lissencephaly, and one had STXBP1 mutation. Fifteen infants failed to respond to adrenocorticotropin hormone and/or vigabatrin before going on the ketogenic diet. Three months after starting the diet, >50% seizure reduction was achieved in 70% of patients (95% CI 48-86). These results were maintained at 6- and 12-month intervals. All eight of the patients followed for 24 months had >50% seizure reduction (95% CI 63-100). At least 90% seizure reduction was reported in 20% of patients at 3 months (95% CI 7-42), 22% (95% CI 8-46) at 6 months, and 35% (95% CI 17-59) at 12 months. The majority of patients (63%) achieved improvement of their spasms within 1 month after starting the diet. Sixty percent of patients had electroencephalographic improvement. All caregivers reported improvement of the quality of life at the 3-month visit (95% confidence interval 81-100). This ratio was 94% at 6 months (95% CI 72-99) and 82% at 12 months (95% CI 58-95).

    A unique case of 'variant' angina pectoris has been observed in a patient with normal coronary arteries and typical chest pain appearing spontaneously at rest, and repeatedly provoked by ergonovine maleate (0.1 mg iv) associated with large transmural perfusion defects on 201 TI-imaging (after ergonovine) and a marked increase in T wave voltage despite no demonstrable spasm of a major coronary artery after the same doses of ergonovine. While saline solution could not provoke chest pain and treatment with a beta-blocking agent increased the frequency of ischemic attacks, a calcium antangonist therapy reduced and eventually eliminated the attacks. Thus, this case provides evidence for yet another aspect of a 'variant' form of angina pectoris: small vessel coronary artery spasm. (orig.) [de

    2017-06-01

    Microvascular decompression (MVD) for hemifacial spasm (HFS) provides resolution of disabling symptoms such as eyelid twitching and muscle contractions of the entire hemiface. The primary aim of this study was to evaluate the predictive value of patient demographics and spasm characteristics on long-term outcomes, with or without intraoperative lateral spread response (LSR) as an additional variable in a risk assessment model. A retrospective study was undertaken to evaluate the associations of pre-operative patient characteristics, as well as intraoperative LSR and need for a staged procedure on the presence of persistent or recurrent HFS at the time of hospital discharge and at follow-up. A risk assessment model was constructed with the inclusion of six clinically or statistically significant variables from the univariate analyses. A receiving operator characteristic curve was generated, and area under the curve was calculated to determine the strength of the predictive model. A risk assessment model was first created consisting of significant pre-operative variables (Model 1) (age >50, female gender, history of botulinum toxin use, platysma muscle involvement). This model demonstrated borderline predictive value for persistent spasm at discharge (AUC .60; p=.045) and fair predictive value at follow-up (AUC .75; p=.001). Intraoperative variables (e.g. LSR persistence) demonstrated little additive value (Model 2) (AUC .67). Patients with a higher risk score (three or greater) demonstrated greater odds of persistent HFS at the time of discharge (OR 1.5 [95%CI 1.16-1.97]; p=.035), as well as greater odds of persistent or recurrent spasm at the time of follow-up (OR 3.0 [95%CI 1.52-5.95]; p=.002) Conclusions: A risk assessment model consisting of pre-operative clinical characteristics is useful in prognosticating HFS persistence at follow-up.

    Objective: To investigate the mechanism of reverse redistribution (RR) on dipyridamole 201 Tl myocardial perfusion studies in the patients with coronary artery spasm. Methods: Twenty-six patients with coronary artery spasm and presented as RR on dipyridamole 201 Tl myocardial perfusion studies were enlisted as RR group, while other 16 patients with no coronary artery stenosis nor RR were enlisted as control group. Dipyridamole test was repeated during coronary angiography. Corrected thrombolysis in myocardial infarction (TIMI) frame count (CTFC) and TIMI myocardial perfusion grade (TMPG) were measured at RR related and non-RR related coronary arteries before and after dipyridamole infusion respectively. All of the data were analyzed by Student's t-test or χ 2 -test and correlation analysis. Results: Coronary artery angiography showed slower blood flow and lower myocardial perfusion in RR related vessels when compared with non-RR related vessels in RR group, but there was no significant difference among the main coronary arteries in control group. The perfusion defects of RR area at rest were positively related to slower blood velocity at corresponding coronary arteries (r = 0.79, t =10.18, P 0.05). Conclusion: RR is related to the decreased blood flow and myocardial perfusion induced by coronary artery spasm at rest, which may be improved by stress test such as intravenous dipyridamole infusion.

    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. 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 10cm 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. 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. In this case, the patient's symptoms spontaneously resolved without any treatment; however, longer-term follow-up is needed. Copyright © 2015 The Authors. Published by Elsevier Ltd..

    The two main sources of blood supply to the lungs and their supporting structures are the pulmonary and bronchial arteries. The bronchial arteries account for 1% of the cardiac output but can be recruited to provide additional systemic circulation to the lungs in various acquired and congenital thoracic disorders. An understanding of bronchial artery anatomy and function is important in the identification of bronchial artery dilatation and anomalies and the formulation of an appropriate differential diagnosis. Visualization of dilated bronchial arteries at imaging should alert the radiologist to obstructive disorders that affect the pulmonary circulation and prompt the exclusion of diseases that produce or are associated with pulmonary artery obstruction, including chronic infectious and/or inflammatory processes, chronic thromboembolic disease, and congenital anomalies of the thorax (eg, proximal interruption of the pulmonary artery). Conotruncal abnormalities, such as pulmonary atresia with ventricular septal defect, are associated with systemic pulmonary supply provided by aortic branches known as major aortopulmonary collaterals, which originate in the region of the bronchial arteries. Bronchial artery malformation is a rare left-to-right or left-to-left shunt characterized by an anomalous connection between a bronchial artery and a pulmonary artery or a pulmonary vein, respectively. Bronchial artery interventions can be used successfully in the treatment of hemoptysis, with a low risk of adverse events. Multidetector computed tomography helps provide a vascular road map for the interventional radiologist before bronchial artery embolization. RSNA, 2015

    Objective: The arterial spasm which often seen in the coronary angiography was considered as a result of the pathological spasm of the coronary artery or a complication of catheterization. The coronary arterial spasm is a considerable situation because it increases the danger of stenotic lesions in coronary artery, which should be managed immediately. Methods: In total 37 patients presented with coronary arterial spasm in the coronary angiography (Judkins method): 23 male and 14 female, aged 43-60 years (the 47 years in average). Spasms were relieved in all patients after the administration of glonoin. Results: Solitary spasm were the most common, the angiographic findings were long section (>10 mm) with stenosis of 50%-65% in left anterior descending artery (12 cases), or in the middle and near portion of the right coronary artery (5 cases), where the orifice of the branches were involved; severe stenosis of the orifice of the right coronary artery (3 cases); irregular, mild and local spasm in left anterior descending artery or circumflex (8 cases). And multiple spasm was observed in left anterior descending artery (4 cases) or in the right coronary artery (5 cases). In 19 cases, stenosis accompanying with spasm were revealed and local spasm were observed at the site of arterial sclerosis. Conclusion: The spasm owing to the catheterization doesn't result in chest discomfort and changes in EKG, while pathological spasm occurs in the population with high risk of coronary heart disease, which indicates the potential myocardial infraction.

    Six cases of rare bronchial anomalies are presented (3 complete rightsided hyparterial bronchial distributions, 1 partial rightsided hyparterial bronchial supply of the upper lobe, 2 cases of atresia of the left apico-posterior bronchus). Emphasis is placed on the bronchographic elucidation of the changed bronchial segmental topic if additive or subtractive bronchial anomalies are found endoscopically especially with regard to preoperative aspects.

    Thirteen bronchial arterial perfusion studies were performed in a total of 13 patients with lung tumors (11 cases of lung cancer, one metastatic tumor and one abscess), utilizing 99m TcO 4 - or 99m Tc-labeled macroaggregated albumin ( 99m Tc-MAA). Regions of interest (ROI) of the same size were set over areas of tumor, the mediastinum and healthy lung areas, and each ROI count was calculated by a nuclear medicine computer during an acquisition time period of 20 min with each tracer for 7 min to evaluate tumor part perfusion. The count ratios of tumor to healthy parts ranged from 1.7 to 6.5 (mean±s.d.; 3.8±1.9) in the 99m TcO 4 - group (10 patients) and from 130 to 230 (mean±s.d.; 163±30) in the 99m Tc-MAA group (3 patients), respectively. Tumor reduction rates 2 weeks after CDDP bronchial artery infusion therapy correlated positively to the count ratio in the 99m TcO 4 - lung cancer group, although significant correlation was not obtained. This study suggests that bronchial arterial infusion of anticancer agents may result in higher concentrations of anticancer agents in the tumors than with systemic chemotherapy and chemoembolic materials may exert more potent anticancer effects on tumors than nonparticulated anticancer agents.

    To focus on both positive and negative aspects of the interaction between asthmatic patients and the social networks, and to highlight the need of a psychological approach in some individuals to integrate pharmacological treatment is the purpose of review. There is evidence that in some asthmatic patients, the excessive use of social networks can induce depression and stress triggering bronchial obstruction, whereas in others their rational use can induce beneficial effects in terms of asthma management. The increasing asthma prevalence in developed countries seen at the end of last century has raised concern for the considerable burden of this disease on society as well as individuals. Bronchial asthma is a disease in which psychological implications play a role in increasing or in reducing the severity of bronchial obstruction. Internet and, in particular, social media are increasingly a part of daily life of both young and adult people, thus allowing virtual relationships with peers sharing similar interests and goals. Although social network users often disclose more about themselves online than they do in person, there might be a risk for adolescents and for sensitive individuals, who can be negatively influenced by an incorrect use. However, although some studies show an increased risk of depression, other observations suggest beneficial effects of social networks by enhancing communication, social connection and self-esteem.

    According to the authors' experience so far, 201 Tl myocardial scintiscanning is a sufficiently sensitive non-invasive method for detection of coronary vasospasm provoked by ergotamine administration. Mild incomplete and asymptotic forms of coronary vasospasm were detected by scintiscanning. Indications for myocardial scintiscanning of ergotamine-provoked vasospasm are: Cases of angina pectoris at rest in which electrocardiograms during spasm are not available; elleviated symptoms after nitroglycerine administration; exercise electrocardiograms without any sign of ischaemia; negative results of exercise 201 Tl myocardial scintiscanning.

    Hemifacial spasm characterized by involuntary paroxistic contractions of the face is more frequent on left side and in females. Evolution is progressive and in a few cases may disappear. Management includes medical treatment, botulinum toxin, and microvascular decompression of the nerve. We present the results of 116 microvascular decompressions performed in 88 patients over 10 years. All patients had previous medical treatment. All patients were operated on with microsurgical technique by asterional craniotomy. Vascular compression was present in all cases with one exception. Follow-up was from 1 month to 133 months. Were achieved excellent results in 70.45% of cases after first operation, good results in 9.09%, and poor results in 20.45% of patients. Long-term results were excellent in 81.82%, good in 6.82%, and poor in 11.36% of patients. Hypoacusia and transitory facial palsy were the main complications. Hemifacial spasm is a painless but disabling entity. Medical treatment is effective in a limited fashion. Injection of botulinum toxin has good response but benefit is transitory. Microvascular decompression is treatment of choice because it is minimally invasive, not destructive, requires minimum technical support, and yields best long-term results.

    The objective of the present work was to search for the tissue and cellular markers of remodeling of bronchial mucosa in the patients with different clinical forms of bronchial asthma (BA). The use of up-to-date morphometric techniques has demonstrated that mild and moderately severe forms of bronchial asthma are accompanied by the development of Th2-immune response associated with increased production of interleukin-4 and marked degranulation of eosinophilic granulocytes resulting in desquamation of epithelium and goblet cell hyperplasia. The severe BA phenotype of "chronic asthma with fixed obstruction" is associated with the development of non-atopic inflammation in the bronchial mucous membrane that manifests itself as the increased concentration of interleukin-8 in bronchial mucosa and its neutrophilic infiltration leading to the development of pronounced subepithelial fibrosis, thickening of the basal membrane, and atrophy of epithelium. Specific structural changes in bronchial mucosa of the patients presenting with BA underlie functional disturbances that cause severe bronchial obstructive syndrome.

    In patients with bronchial tumors, we frequently consider endoscopic treatment as the first treatment of choice. All computed tomography (CT) must satisfy several conditions necessary to analyze images by Synapse Vincent. To select safer and more precise approaches for patients with bronchial tumors, we determined the indications and efficacy of virtual navigation intervention for the treatment of bronchial tumors. We examined the efficacy of virtual navigation bronchial intervention for the treatment of bronchial tumors located at a variety of sites in the tracheobronchial tree using a high-speed 3-dimensional (3D) image analysis system, Synapse Vincent. Constructed images can be utilized to decide on the simulation and interventional strategy as well as for navigation during interventional manipulation in two cases. Synapse Vincent was used to determine the optimal planning of virtual navigation bronchial intervention. Moreover, this system can detect tumor location and alsodepict surrounding tissues, quickly, accurately, and safely. The feasibility and safety of Synapse Vincent in performing useful preoperative simulation and navigation of surgical procedures can lead to safer, more precise, and less invasion for the patient, and makes it easy to construct an image, depending on the purpose, in 5-10 minutes using Synapse Vincent. Moreover, if the lesion is in the parenchyma or sub-bronchial lumen, it helps to perform simulation with virtual skeletal subtraction to estimate potential lesion movement. By using virtual navigation system for simulation, bronchial intervention was performed with no complications safely and precisely. Preoperative simulation using virtual navigation bronchial intervention reduces the surgeon's stress levels, particularly when highly skilled techniques are needed to operate on lesions. This task, including both preoperative simulation and intraoperative navigation, leads to greater safety and precision. These technological instruments

    Spasm of the near reflex has been characterized as the variable appearance of pseudomyopia, convergent strabismus and miosis. These characteristics may appear together or separately. In addition, abnormalities of accommodation may appear not only as pseudomyopia, but may also be manifest in cases with significant hypermetropia in which the patient is unable to relax accommodation even when plus lenses are used. The intent of this review is to identify the various clinical presentations of anomalies of the entire near reflex as well as the component parts. The relationship to functional and organic disorders are discussed as well as the related neuroanatomy. We suggest that one may more readily understand the clinical manifestations as a spectrum of anomalies of the near reflex rather than a multitude of disconnected entities.

    Spasm of the near reflex (SNR) is a triad of miosis, excess accommodation and excess convergence. Primary SNR is most often functional in origin We aim to highlight the clinical features which distinguish primary convergence from other conditions with a similar presentation but more sinister underlying aetiology, for example bilateral abducens nerve palsy. There is a paucity of published data on SNR, in particular diagnostic criteria and treatment. We report a case of SNR of functional origin in an otherwise healthy young female and discuss the clinical features that differentiate this condition from similar conditions with underlying neurological origin. SNR is predominantly a clinical diagnosis, and often leads to patients undergoing unnecessary investigations and sometimes treatment. Recognising the salient features that differentiate it could potentially avoid this.

    Full Text Available The diagnosis of child maltreatment leading to head injury is challenging. Here, we present the case of a 3-month-old female infant who presented with focal seizures that lasted for several minutes. After admission, she began to show intermittent clusters of head nods, irritable crying, arching, writhing, stiffening, and jerking of both arms. These results and electroencephalography findings were attributed as the diagnosis of infantile spasms (IS. Brain computed tomography and magnetic resonance imaging (MRI revealed the presence of chronic subdural hematoma mixed with acute ischemic injuries. Examination of the eye fundus confirmed the presence of retinal hemorrhage. Therefore, all evidence pointed to a diagnosis of shaken baby syndrome (SBS. Based on this case, we suggest that physicians should consider a diagnosis of SBS for children with new-onset IS and that should be evaluated, diagnosed, and treated as promptly as possible.

    We describe a patient with idiopathic hemifacial spasm (HFS) that was responsive to zonisamide treatment. A 65-year-old woman presented with a 4-year history of left-sided HFS developing gradually, starting from the upper facial muscles. After several analyses, the diagnosis of idiopathic HFS was made, and the clonazepam treatment (0.5 mg every 8 hours) was started, without a complete remission of symptoms. Therefore, zonisamide (150 mg twice a day for a 6-week period) was added, with a complete resolution. The rechallenge with zonisamide after its dechallenge confirmed its effectiveness. During follow-up, the patient remained symptom-free, with no adverse drug reactions. We suggest that zonisamide could represent a useful therapeutic option in the treatment of idiopathic HFS.

    Paroxysmal painful tonic spasms (PPTS) were initially described in multiple sclerosis (MS) but they are more frequent in neuromyelitis optica (NMO). The objective is to report their presence in a series of cases of NMO and NMO spectrum disorders (NMOSD), as well as to determine their frequency and clinical features. We conducted a retrospective assessment of medical histories of NMO/NMOSD patients treated in 2 hospitals in Buenos Aires (Hospital Durand and Hospital Álvarez) between 2009 and 2013. Out of 15 patients with NMOSD (7 with definite NMO and 8 with limited NMO), 4 presented PPTS (26.66%). PPTS frequency in the definite NMO group was 57.14% (4/7). Of the 9 patients with longitudinally extensive transverse myelitis (LETM), 44.44% (9/15) presented PPTS. Mean age was 35 years (range, 22-38 years) and all patients were women. Mean time between NMO diagnosis and PPTS onset was 7 months (range, 1-29 months) and mean time from last relapse of LETM was 30 days (range 23-40 days). LETM (75% cervicothoracic and 25% thoracic) was observed by magnetic resonance imaging (MRI) in all patients. Control over spasms and pain was achieved in all patients with carbamazepine (associated with gabapentin in one case). No favourable responses to pregabalin, gabapentin, or phenytoin were reported. PPTS are frequent in NMO. Mean time of PPTS onset is approximately one month after an LETM relapse, with extensive cervicothoracic lesions appearing on the MRI scan. They show an excellent response to carbamazepine but little or no response to pregabalin and gabapentin. Prospective studies with larger numbers of patients are necessary in order to confirm these results. Copyright © 2014 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U.

    Full Text Available Purpose: Infantile spasms are described as flexor extensor and mixed; but more features of their semiology and ictal electroencephalography (EEG changes are sparse in the literature. The purpose of the study was to describe the clinical and ictal video-EEG characteristics of consecutive cases with infantile spasms and to try to find an association with the etiology. Materials and Methods: The clinical phenomenology and EEG characteristics on video-EEG were analyzed in 16 babies with infantile spasms. Results: A total of 869 spasms were reviewed. Nine (56.3% showed focal seizures at least once during the recording and 1 (6.3% had multifocal myoclonus in addition to the spasms. The duration of the cluster and interval between spasms was totally variable in all patients. Lateralizing phenomena were present in at least some of the spasms in all patients. Unilateral manual automatism in the form of holding the pinna was noted in three patients following the spasm. The ictal EEG activity in the majority (75% was the slow wave. Four (25% showed fast generalized spindle-like ictal discharges. Spikes, spike and wave activity, or electrodecremental pattern alone during the ictus was seen in none. On bivariate analysis, no factor noted on the video EEG had association with the etiology. Conclusion: Infantile spasms could be associated with focal and other seizures, has unique, non-uniform and variable semiology from patient to patient. The ictal EEG manifestation in the majority (75% of our patients was the slow wave transient with 25% showing generalized fast spindle-like activity.

    2017-06-01

    Full Text Available Malformations of cortical development (MCDs can cause medically intractable epilepsies and cognitive disabilities in children. We developed a new model of MCD-associated epileptic spasms by treating rats prenatally with methylazoxymethanol acetate (MAM to induce cortical malformations and postnatally with N-methyl-d-aspartate (NMDA to induce spasms. To produce cortical malformations to infant rats, two dosages of MAM (15 mg/kg, intraperitoneally were injected to pregnant rats at gestational day 15. In prenatally MAM-exposed rats and the controls, spasms were triggered by single (6 mg/kg on postnatal day 12 (P12 or 10 mg/kg on P13 or 15 mg/kg on P15 or multiple doses (P12, P13, and P15 of NMDA. In prenatally MAM-exposed rats with single NMDA-provoked spasms at P15, we obtain the intracranial electroencephalography and examine the pretreatment response to adrenocorticotropic hormone (ACTH or vigabatrin. Rat pups prenatally exposed to MAM exhibited a significantly greater number of spasms in response to single and multiple postnatal NMDA doses than vehicle-exposed controls. Vigabatrin treatment prior to a single NMDA dose on P15 significantly suppressed spasms in MAM group rats (p < 0.05, while ACTH did not. The MAM group also showed significantly higher fast oscillation (25–100 Hz power during NMDA-induced spasms than controls (p = 0.047. This new model of MCD-based epileptic spasms with corresponding features of human spasms will be valuable for future research of the developmental epilepsy.

    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.

    Until now, it is unknown whether and to what extent arteriosclerotic disease affects the bronchial arteries. We conducted this pilot study to estimate the prevalence of arteriosclerosis of the bronchial arteries, to correlate it with certain clinicolaboratory arteriosclerotic parameters or any coexistent coronary artery disease (CAD) and to validate the clinical significance. Bronchial arteries 10-15 mm long were obtained from 40 patients with a mean age of 62.3 years who underwent major thoracic procedures. Their medical history and detailed clinical and laboratory arteriosclerotic risk factors were documented. The mean diameter of bronchial artery specimens was 0.97 mm. Histology revealed medial calcific sclerosis only in 1 patient (2.5%) without simultaneous, established atherosclerotic lesions or narrowing of the lumen. Furthermore, the vessel diameter was significantly correlated not only with the advanced stage of the disease (p = 0.031), but also with the proximal occlusion of the bronchial tree (p = 0.042). We noted a marginally not significant correlation between arteriosclerosis and metabolic syndrome (p = 0.075), independent from a history of CAD (p = 0.84). Bronchial arteries exhibit only medial calcific sclerosis. CAD and chronic obstructive pulmonary disease do not seem to affect them in terms of atherosclerotic alteration findings or vessel diameter changes. The bronchial resistance to arteriosclerosis might support the mediastinal status quo through their anastomoses, contributing to all its structures, and might be indirect evidence of a different physiological function of the bronchial endothelium, which needs to be further investigated.

    1986-01-01

    Hemifacial spasm is characterized by unilateral, periodic, tonic contractions of facial muscles, thought to be caused by mechanical compression at the root-exit zone of the facial nerve. Electrophysiologic abnormalities such as ectopic excitation and synkinesis are typical. Although posterior fossa microsurgical nerve decompression is successful in bringing about relief of the spasm in most cases, it carries a risk to hearing. As an alternative treatment, 15 patients with hemifacial spasm were given a total of 41 sets of injections with botulinum A toxin, with a mean follow-up of 14.3 +/- 1.1 months. Relief of symptoms lasted a mean of 108.3 +/- 4.2 days. Mild transient lagophthalmos and ptosis were the only complications. Although the exact mechanism of its action and beneficial effect is speculative at this time, botulinum A toxin appears to offer an effective, safe alternative to more radical intracranial surgery for patients with hemifacial spasm.

    Objective: To explore an effective way to treat the vascular spasm occurred during TACE for hepatocellular carcinomas. Methods: During interventional chemoembolization for hepatocellular carcinomas, Fasudil of 2.5 mg was injected via the catheter if vessel spasm occurred, which was followed by DSA to determine the dilatation of the arteries. Adverse effect was observed and recorded. Results: After the injection of Fasudil the vascular spasm was completely relieved in all the 30 cases. The interventional procedure for hepatocellular carcinomas was successfully accomplished in all patients. No obvious side effect occurred. Conclusion: The injection of Fasudil via the catheter is an effective and safe method to eliminate vessel spasm occurred during TACE for hepatocellular carcinomas. (authors)

  2. Recent developments regarding periostin in bronchial asthma

    2015-09-01

    Full Text Available Although it is currently recognized that bronchial asthma is not a single disease but a syndrome, we have not yet made use of our new understanding of this heterogeneity as we treat asthma patients. To increase the efficacy of anti-asthma drugs and to decrease costs, it is important to stratify asthma patients into subgroups and to develop therapeutic strategies for each subgroup. Periostin has recently emerged as a biomarker for bronchial asthma, unique in that it is useful not in diagnosis but in categorizing asthma patients. We first found that periostin is a novel component of subepithelial fibrosis in bronchial asthma downstream of IL-13 signals. Thereafter, it was shown that periostin can be a surrogate biomarker of type 2 immune responses, the basis of the notion that a detection system of serum periostin is potentially a companion diagnostic for type 2 antagonists. Furthermore, we have recently shown that serum periostin can predict resistance or hyporesponsiveness to inhaled corticosteroids, based on its contribution to tissue remodeling or fibrosis in bronchial asthma. Thus, serum periostin has two characteristics as a biomarker for bronchial asthma: it is both a surrogate biomarker of type 2 immune responses and a biomarker reflecting tissue remodeling or fibrosis. We can take advantage of these characteristics to develop stratified medicine in bronchial asthma.

  3. Frontal infraslow activity marks the motor spasms of anti-LGI1 encephalitis.

    The clinical and electrographic features of seizures in anti-LGI1 encephalitis are distinct from those seen in other autoimmune encephalitides or non-encephalitic epilepsies. One electroclinical phenomenon specific to the condition consists of lateralized motor spasms, known as faciobrachial dystonic seizures (FBDS). An electrodecremental pattern overriding a "DC shift" has been described as the EEG correlate of these spasms. We sought to further characterize this pre-spasm infraslow activity (ISA). Continuous video-EEG recordings were acquired in four patients with anti-LGI1 encephalitis: each had frequent motor spasms/FBDS as well as frequent subclinical temporal lobe seizures (an independent indicator of anti-LGI1 encephalitis). In artifact-free recordings obtained using clinical amplifiers equipped with a low frequency analog filter of 0.07 Hz, ISA reliably preceded clinical onset of the motor spasms by ∼1.2 s and preceded the electrodecremental pattern by ∼700 ms. Pre-spasm ISA was invariably recorded contralateral to FBDS, with a voltage topographic maximum over the mid frontal region. The pre-movement ISA differed from the Bereitschaftspotential in timing and topography and was an order of magnitude higher in amplitude. Sporadic FBDS that occurred in association with temporal lobe seizures were preceded by identical ISA. The motor spasms of anti-LGI1 encephalitis are preceded by frontal ISA. A paucity of data at the microscale level precludes mechanistic explanations at the macroscale level, or even determination of the relative contributions of neurons and glia in the generation of the ISA. Although fundamental cellular mechanisms await elucidation, the pre-spasm ISA represents a singular and readily identifiable EEG response to this autoimmune brain disorder.

    We report on vascular compression syndrome of the 12th cranial nerve (hypoglossal), an occurrence not previously reported, and demonstrate, through corresponding objective electrophysiological evidence, that microvascular decompression of the hypoglossal nerve root can cure hemilingual spasm. A 52-year-old man had lower face muscle twitching and tongue spasms, which worsened with talking, chewing, or emotional stress. Carbamazepine offered only temporary relief, and relief from injections of botulinum toxin was insignificant. He was referred for surgical treatment. High-resolution magnetic resonance imaging of his posterior fossa contents revealed no obvious evidence of any compressive vessel along the facial nerve, but a compressive vessel along the hypoglossal nerve was apparent. The presence of preoperative tongue spasms encouraged interoperative monitoring of tongue motor responses. The facial nerve exit zone was explored, but microsurgical inspection of the seventh/eighth cranial nerve complex did not reveal any compressive vessel. However, at the anterolateral aspect of the medulla oblongata, the hypoglossal nerve was clearly compressed and distorted laterally by a large tortuous vertebral artery. When the artery was mobilized away from the nerve, the abnormal late electromyographic response to transcranial electrical stimulation disappeared; immediately after shredded Teflon was interpositioned between the artery and the nerve, the abnormal spontaneous tongue fasciculation also disappeared. The patient has remained spasm free 6 months after surgery. Hemilingual spasm may be caused by vascular contact/compression along cranial nerve XII at the lower brainstem and belong to the same family of cranial nerve hyperactivity disorders as hemifacial spasm.

    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.

    To evaluate the effect of hemifacial spasm (HFS) on intraocular pressure (IOP) measurement. Twenty-four consecutive patients with HFS and 25 age- and gender-matched randomly selected eyes of healthy volunteers underwent corneal pachymetry and IOP measurements using Goldmann applanation tonometer (GAT) and noncontact tonometer (NCT). IOP measurements were performed before (during HFS) and 2 weeks after Botox injections in HFS patients and in healthy volunteers without Botox injections. There was no statistical difference between involved eye side and uninvolved eye side of HFS patients in measured central corneal thickness. Similarly, no difference was found between involved eye side of HFS patients and controls. There were no statistically significant differences comparing IOP values before treatment and levels measured at 2 weeks of Botox injections, either with GAT ( p = 0.33, 0.11) or NCT ( p = 0.80, 0.43) devices in the involved eyes and uninvolved eyes of patients with HFS, respectively. There were also no significant differences in these parameters (GAT ( p = 0.63) and NCT ( p = 0.54)) in controls. Contractions in facial muscles may not lead to significant increase in IOP in HFS patients. This result may help clinical decision making in the treatment of glaucoma patients with HFS. This trial is registered with NCT03390803.

    Objective: To evaluate the radiological findings of bronchial mucoid impaction in 28 patients in order to improve diagnostic efficacy. Methods: Standard posteroanterior high voltage radiographs were performed in all 28 cases. Among them CT scans were taken in 14 cases, while 3 patients underwent HRCT examination at the same time. Twenty-two patients had a history of expectoration of mucous plugs; in one case with pulmonary atelectasis, a mucous plug was picked out through bronchoscopy. The other 5 cases experienced a lung operation, and a tumor and bronchial mucoid impaction were discovered. Results: Radiographs showed most mucoid impaction as thick, branching structures resembling branches of tree; others were in the shapes of spherical, small clubs, and cuttle fish. In one patient, pulmonary atelectasis was the only radiographic finding. Similarly on CT, most bronchial mucoid impaction were likened to tree branches; the rest presented as small clubs and bunches of grape. A prominent feature of bronchial mucoid impaction, either on plain radiograph or on CT, was that its axis pointed to the hilum, completely consistent with the branching and distribution of the bronchi, and accompanied by bronchiectasis. Conclusions: It is an optimal approach to exploit plain radiograph combined with CT to find out bronchial mucoid impaction. An awareness of its clinical and radiological features may improve better understanding and recognition of the disease

    Medical records, radiographs, and bronchial cytologic abnormalities of 65 cats with bronchial disease were reviewed. Bronchial disease was defined as abnormality of the lower airways to the exclusion of disease originating or mainly involving the alveoli, interstitium, vasculature, or pleura. Cats with bronchial disease were more likely to be female and older. Siamese cats were over represented and had more chronic disease. In order of frequency, the following clinical signs were reported: coughing, dyspnea, occasional sneezing, wheezing, and vomiting. Radiography revealed prominent bronchial markings, with some cats having collapse of the middle lobe of the right lung (n = 7), overinflation of the lungs (n = 9), or aerophagia (n = 13). Of 65 bronchial washes, 58 were considered exudative, with the predominant cell type being eosinophil in 24%, neutrophil in 33%, macrophage in 22%, and mixed population of cells in 21%. Cultures for bacteria were considered positive in 24% of the cats. Circulating eosinophilia was not helpful in predicting the predominant cell type in bronchial cytologic exudates. Hyperproteinemia without dehydration was present in a third of the cats, indicating an immunologic response. Half the cats had resolution of clinical signs, whereas half the cats required continuing medication with bronchodilators, antimicrobial agents, or corticosteroids

    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.

    Background: Coronary vasospasm is defined as a temporary, intense narrowing of the coronary conduit artery. It brings about ischemic chest pain and becomes one of the causes of myocardial infarction. Coronary spasms are divided into two categories. One is the coronary spasm of the conduit artery and the other is the coronary microvascular spasm. Although coronary spasms are diagnosed with the images of coronary angiography, microvascular spasms cannot be diagnosed because of the limitations of conventional angiographic systems. However, synchrotron radiation coronary angiography (SRCA) can identify coronary arteries down to 100 μm in diameter in the beating heart and 50 μm in arrested heart. Aim: The purpose of this study was to confirm whether microvascular spasms could be identified or not using SRCA, and then down that size identification was possible. Methods: The Langendorff perfusion system with isolated rat hearts was employed. Krebs-Henseleit solution (KH solution) was used as a perfusate. 10 mM of 4-aminopyridine (4-AP: a voltage-gated potassium channel blocker; spasm inducer) was added to the KH solution and maintained for 5 min. SRCA was performed at pre-, during and 10 min after cessation of the KH solution with 4-AP. Coronary spasms were defined as a temporal 75% reduction of coronary arterial diameter. Results and conclusion: Multiple sizes of coronary arteries showed coronary spasms. The minimum stenosed coronary artery size was 100 μm. Since coronary microvascular spasms are seen in the arterioles (50-400 μm), coronary microvascular spasms may be diagnosed with the use of synchrotron radiation coronary angiography

    A previous study reported an increased prevalence of bruxism (25%) in patients with cranio-cervical dystonia (CCD) compared to normal controls (13%). CCD can affect the muscles of the head and neck. Besides the CCD affecting these muscles, hemifacial spasm (HFS) is a form of peripheral myoclonus due to a neurovascular conflict affecting the muscles of the face. The fact that they affect the same muscle regions could lead to other links in clinical manifestations such as bruxism, which is more common in patients with CCD than in the normal population. The aim was to study the prevalence of bruxism in patients with HFS. Patients with HFS were enrolled in the department of clinical neurophysiology (Bordeaux University Hospital) over a 6-month period. They were paired regarding age, the absence of neurological pathology or neuroleptics intake. To be included in the study, patients needed to have had unilateral involuntary facial muscle contractions affecting one hemiface. A hetero-questionnaire and a clinicial study were performed. The diagnostic criteria of bruxism included parafunction items such as grinding and clenching and at least one of the following clinical signs: abnormal tooth wear, temporomandibular joint (TMJ) pain, TMJ clicking, muscle hypertonia (masseter or temporal muscles). Additional epidemiological data were collected including age, sex, disease duration, stress, and sleep disorders. Stress symptoms inventory included symptoms like depression, strong heartbeat, dry mouth, anger, inability to concentrate, weakness, fatigability, insomnia, headache, and excessive sweating. The sleep disorder diagnosis included at least two of the symptoms described in the ICSD-3. All these criteria were recorded as either present (scored "1") or absent (scored "0"). The prevalence of bruxism in the two groups (normal and HFS) was not significantly different (p = 0.37). The rate was not significantly different between sleep and awake bruxism (p = 0.15) in both groups

    Intermittent exotropia (IXT) is an exodeviation intermittently controlled by fusional mechanisms. Patients with IXT may present with asthenopic symptoms, blurred vision, headaches, diplopia or visual confusion and reading difficulties; especially after prolonged periods of near work. To report the presentation and management of a young adult with intractable accommodative spasm secondary to long standing intermittent exotropia. The patient was found to have bilateral accommodative spasm with high pseudomyopia and severe impairment of vision. There was a tendency for recurrence with discontinuation of cycloplegics. A total relief of symptoms was noticed after strabismus surgery was undertaken for the exotropia. A detailed orthoptic evaluation with emphasis on recognizing accommodative spasm as an unusual presentation of IXT, could aid in appropriate diagnosis and treatment of such cases. © NEPjOPH.

    Full Text Available Objectives: The main purpose of this research is to investigate the effect of treatment with Hominis Placental pharmacopuncture (HPP for 32 patients with hemifacial spasm. Methods: We treated facial spasm patients with acupuncture and HPP at Sabaek (ST2, Seung-eup (ST1, Gwallyeo (SI18, Chanjuk (BL2, Sajukgong (TE23, Hagwan (ST7, Hyeopgeo (ST6, Jichang (ST4, Wan-gol (SI4 and Yepung (TE17, and we investigated the effect by using Scott’s scale. The data were analyzed by using the SPSS/10.0 for windows program with descriptive statistics, the paired t-test, and the Shapiro-Wilk normality test. Results: After treatment, the grade of the spasm’s intensity based on Scott’s description were decreased significantly. About 72% of the patients felt that the combination treatment had produced excellent results. Conclusion: These data suggested that HPP can be useful for treating facial spasm patients.

  15. MOTOR UNIT FIRING RATES DURING SPASMS IN THENAR MUSCLES OF SPINAL CORD INJURED SUBJECTS

    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.

    The purpose of this investigation was to compare the response of human cell types (bronchial epithelial cells and fibroblasts and skin fibroblasts) to various DNA damaging agents. Repair of DNA single strand breaks (SSB) induced by 5 krads of X-ray was similar for all cell types; approximately 90% of the DNA SSB were rejoined within one hour. During excision repair of DNA damage from u.v.-radiation, the frequencies of DNA SSB as estimated by the alkaline elution technique, were similar in all cell types. Repair replication as measured by BND cellulose chromatography was also similar in epithelial and fibroblastic cells after u.v.-irradiation. Similar levels of SSB were also observed in epithelial and fibroblastic cells after exposure to chemical carcinogens: 7,12-dimethylbenz[a]anthracene; benzo[a]pyrene diol epoxide (BPDE); or N-methyl-N-nitro-N-nitrosoguanidine. Significant repair replication of BPDE-induced DNA damage was detected in both bronchial epithelial and fibroblastic cells, although the level in fibroblasts was approximately 40% of that in epithelial cells. The pulmonary carcinogen asbestos did not damage DNA. DNA-protein crosslinks induced by formaldehyde were rapidly removed in bronchial cells. Further, epithelial and fibroblastic cells, which were incubated with formaldehyde and the polymerase inhibitor combination of cytosine arabinoside and hydroxyurea, accumulated DNA SSB at approximately equal frequencies. These results should provide a useful background for further investigations of the response of human bronchial cells to various DNA damaging agents

    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.

    Objective: To summarize the gene mutation of early onset epileptic spasm with unknown reason. Method: In this prospective study, data of patients with early onset epileptic spasm with unknown reason were collected from neurological department of Children's Hospital of Fudan University between March 2016 and December 2016. Patients with known disorders such as infection, metabolic, structural, immunological problems and known genetic mutations were excluded. Patients with genetic disease that can be diagnosed by clinical manifestations and phenotypic characteristics were also excluded. Genetic research methods included nervous system panel containing 1 427 epilepsy genes, whole exome sequencing (WES), analysis of copy number variation (CNV) and karyotype analysis of chromosome. The basic information, phenotypes, genetic results and the antiepileptic treatment of patients were analyzed. Result: Nine of the 17 cases with early onset epileptic spasm were boys and eight were girls. Patients' age at first seizure onset ranged from 1 day after birth to 8 months (median age of 3 months). The first hospital visit age ranged from 1 month to 2 years (median age of 4.5 months). The time of following-up ranged from 8 months to 3 years and 10 months. All the 17 patients had early onset epileptic spasm. Video electroencephalogram was used to monitor the spasm seizure. Five patients had Ohtahara syndrome, 10 had West syndrome, two had unclear classification. In 17 cases, 10 of them had detected pathogenic genes. Nine cases had point mutations, involving SCN2A, ARX, UNC80, KCNQ2, and GABRB3. Except one case of mutations in GABRB3 gene have been reported, all the other cases had new mutations. One patient had deletion mutation in CDKL5 gene. One CNV case had 6q 22.31 5.5MB repeats. Ten cases out of 17 were using 2-3 antiepileptic drugs (AEDs) and the drugs had no effect. Seven cases used adrenocorticotropic hormone (ACTH) and prednisone besides AEDs (a total course for 8 weeks

    106 patients with inoperable malignant tumours constricting the central bronchial tree underwent endobronchial small-field radiotherapy with iridium-192 at high dose between June 1983 and September 1985. Treatment was performed using the computer-guided after-loading technique and a flexible bronchoscope under local anaesthesia. In complete occlusion of a bronchus by the tumour, a neodymium YAG-laser was applied (57 patients) to allow insertion of the afterloading probe. Endoscopy showed tumour regression in 75% of the patients, accompanied by clinical improvement. Pulmonary function tests, arterial blood gas analyses and pulmonary perfusion scans yielded a highly significant improvement of data after treatment. The procedure also proved effective upon exhaustion of external radiation. Apart from its positive palliation, endobronchial small-field radiotherapy using high doses of iridium-192 also has a curative effect, thus opening up a new approach to the therapy of advanced bronchial carcinoma.

    Numerous studies have suggested that the ketogenic diet is effective in the treatment of epileptic spasms, even in refractory cases. However, there has been very limited demonstration of prompt and complete (video-EEG confirmed) response. We set out to describe our center's experience with the ketogenic diet in the treatment of children with highly refractory epileptic spasms, with rigorous seizure outcome assessment. Children treated with the ketogenic diet for epileptic spasms between April, 2010 and June, 2014 were retrospectively identified. Seizure burden was tabulated at baseline and after 1, 3, 6, and 12-months of ketogenic diet exposure. Adverse events were similarly ascertained. We identified a cohort of 22 consecutive patients who received ketogenic diet therapy, with median age of onset of epileptic spasms of 5.2 (IQR 2.0-9.0) months, with diet initiation beginning a median of 26.4 (12.5-38.7) months after onset, and following a median of 7 (IQR 5-7) treatment failures. Only 2 patients exhibited a complete response during ketogenic diet exposure, and response was more reasonably attributed to alternative therapies in both cases. A modest early reduction in seizure frequency was not sustained beyond 1 month of diet exposure. The diet was well tolerated, and continued in 6 patients with subjective and/or partial response. In contrast to prior studies reporting substantial efficacy of the ketogenic diet, our findings suggest limited efficacy, albeit in a highly refractory cohort. Prospective studies in both refractory and new-onset populations, with both video-EEG confirmation of response and rigorous cognitive outcome assessment, would be of great value to more clearly define the utility of the ketogenic diet in the treatment of epileptic spasms.

    Objective: To discuss the incidence and clinical predictors of radial artery spasm occurred in performing transradial coronary intervention for coronary heart disease. Methods: A total of 1020 patients, who underwent transradial coronary procedures for coronary heart disease during the period of May 2007 Jan 2010 in authors' hospital, were enrolled in this study. All clinical information and medication were recorded in detail. Arteriography via radial artery was performed in all patients. The diameter of the radial artery as well as the arterial anatomy, including arterial variations, were determined and observed, which was follow by coronary angiography or percutaneous coronary intervention. Multivariate Logistic regression analysis was adopted to evaluate the variables, such as clinical parameters, angiographic characteristics of the radial artery and procedure-related factors, in predicting the occurrence of radial artery spasm. Results: Radial artery spasm occurred in 209 (20.5%) patients. Multivariate Logistic regression analysis showed that the following eight factors were independently associated with the occurrence of radial artery spasm. These factors were as follows: female gender (OR=2.8, 95% CI 2.5-5.8; P=0.001), age (OR=0.68, 95% CI 0.60-0.92; P=0.003), smoking (OR=2.3, 95% CI 1.8-4.1; P=0.026), moderate-to-severe pain of forearm during radial artery cannulation (OR=3.0, 95% CI 2.3-4.8; P=0.006), radial artery anatomical abnormalities (OR=4.7, 95% CI 3.6-7.2; P=0.002), the ratio of radial artery diameter to patient's height (RAH) (OR=5.2, 95% CI 3.7-8.1; P=0.012), the ratio of radial artery diameter to outer diameter of the sheath (RAOD) (OR=5.8, 95% CI 4.2-6.9; P=0.006) and the number of catheter exchange (OR=2.3, 95% CI 1.4-4.3; P=0.038). Conclusion: Radial artery spasm occurred in performing transradial coronary intervention for coronary heart disease is frequently seen in clinical practice. Female gender, younger age, smoking, forearm pain during

    A five-and-a-half-year-old girl started experiencing progressive left hemiparesis at age two and a half years. At age five years and four months she started presenting clusters of asymmetric periodic epileptic spasms with no hypsarrhythmia. The ictal EEG showed periodic, constant and stereotyped complexes. Serial brain imaging revealed progressive atrophy of the right hemisphere with increased T2 signal on MRI. She underwent a right hemispherotomy, and histological examination showed signs of inflammation and features of focal cortical dysplasia (FCD). She has been seizure-free for 16 months. This case is unique in the following aspects: the presence of typical Rasmussen encephalitis features of progressive unilateral brain involvement without seizures, a delay of almost three years prior to seizure onset; an atypical seizure type presentation with periodic epileptic spasms and the presence of FCD associated with inflammatory changes.

    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.

    A study on obstructive changes in airways and mucociliary clearance in children and youth with bronchial asthma was performed. Radioaerosol inhalation lung scintigraphies using 99T c-human serum albumin (HSA) were applied to 50 children and youth with bronchial asthma. The deposition patterns of the radioaerosol and aerosol clearance curves were evaluated. Abnormal deposition patterns, which consisted of non-homogeneous distribution and/or hot spot formation, were likely to be seen in patients with asthmatic attacks at the time of measurements. However, a few asymptomatic patients also revealed abnormal deposition patterns. The deposition patterns were related to FEV 1.0 %, MMF, V 50 and V 25 , but especially to FEV 1.0 %. As an index of mucociliary clearance, β, the rate constant of the 99m Tc-HSA aerosol clearance curve, was introduced. β was significantly lower in patients with abnormal aerosol deposition patterns than in normal persons. β was also significantly lower in patients undergoing asthmatic attack at the time of the measurements than in asymptomatic patients. β correlated negatively with FEV 1.0 %, MMF, V 50 and V 25 , but especially with FEV 1.0 %. Although patients with long term affection or moderate-to-severe asthma tended to reveal abnormal deposition patterns and had low β values, these differences were not statistically significant. Radioaerosol inhalation lung scintigraphy with 99m Tc-HSA is useful for evaluating not only obstructive changes in the airways but also for evaluating mucociliary clearance in children with bronchial asthma.

    Full Text Available Continuous positive airways pressure (CPAP is a well known and safe method of treatment patients with obstructive sleep apnoea syndrome (OSAS. The effects of CPAP administration on the upper respiratory tract are known. However its effects on the lower respiratory tract still needs to be determined. Studies on bronchial hyperreactivity in patients treated by CPAP are contradictory. The aim of the study was to assess the influence of a 3-week CPAP treatment in patients with OSAS and to evaluate associations between changes in bronchial reactivity and clinical features of OSAS and lung function tests (LFT. Patients with newly diagnosed OSAS and lack of infection or chronic illness of the respiratory tract or other conditions which could influence bronchial hyperreactivity (BHR were included. Investigations were performed in 101 patients. There were 88 males and 13 females, mean age 51.5±11.2 years and BMI 32.6±5.4 kg·m–2. Qualified patients were randomly divided into 2 groups: 76 patients to CPAP treatment group, 25 control group. Both groups did not differ in anthropometrics features, severity of OSAS and LFT. Metacholine challenge test (MchCT was performed at baseline and repeated after 3 weeks. Analysis of the individual results showed that in 11 patients the MchCT was positive (6 in the CPAP and 5 in the control groups. After 3 weeks in the group of CPAP treated patients an increase of BHR was noted. Log PC20M decreased from 1.38±0.3 to 1.26±0.5 (p<0.05. The number of patients with a positive result in the MchCT increased from 6 to 16 patients. There was no significant change in BHR in the control group. It was found that CPAP treated patients with BHR were older, had less severe OSAS and lower FEV1 (p<0.05. In none of the patients positive result of BHR did no affect compliance to CPAP treatment. Conclusions: CPAP therapy increases bronchial reactivity, but does not affect compliance to treatment.

    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 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 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 in 1.7 patients

    Full Text Available Background. A variant form of angina pectoris (VAP is caused by coronary vessel spasm and occures in patients with and without varying degrees of obstructive coronary artery disease. Although the prognosis of VAP without significant organic stenosis is generally good, multivessel spasm is associated with a high risk of life-threatening abnormalities of rhythm and conduction.Patient and methods. We describe a patient who presented with prolonged chest pain, associated with hypotension, lost of consciousness, complete AV block and widespread ST segment elevations consistent with inferoanterior acute myocardial infarction. Urgent selective coronary angiography revealed spasms in right coronary artery and in left circumflex artery that were relieved by intracoronary injection of nitroglycerin. All coronary arteries were otherwise patient, without signs of atherosclerosis. The patient was treated with diltiazem and nitrates. She made a complete recovery and resumed her normal activities.Conclusions. Simultaneous multiple spasms of native coronary arteries represent a rare syndrome characterized by significantly higher incidence of potentially life-threatening arrhythmia. Less commonly, prolonged coronary spasm may mimic acute myocardial infarction. Modern management of acute coronary syndromes, including urgent coronarography, enables a prompt differentiation between prolonged coronary spasm and atherosclerotic coronary disease, warranting different treatment strategies. Medical treatment with nitrates and calcium channel blockers in most cases prevents recurrence of vasospasms and arrhythmias.

    This study investigated the roles of vaginal spasm, pain, and behavior in vaginismus and the ability of psychologists, gynecologists, and physical therapists to agree on a diagnosis of vaginismus. Eighty-seven women, matched on age, relationship status, and parity, were assigned to one of three groups: vaginismus, dyspareunia resulting from vulvar vestibulitis syndrome (VVS), and no pain with intercourse. Diagnostic agreement was poor for vaginismus; vaginal spasm and pain measures did not differentiate between women in the vaginismus and dyspareunia/VVS groups; however, women in the vaginismus group demonstrated significantly higher vaginal/pelvic muscle tone and lower muscle strength. Women in the vaginismus group also displayed a significantly higher frequency of defensive/avoidant distress behaviors during pelvic examinations and recalled past attempts at intercourse with more affective distress. These data suggest that the spasm-based definition of vaginismus is not adequate as a diagnostic marker for vaginismus. Pain and fear of pain, pelvic floor dysfunction, and behavioral avoidance need to be included in a multidimensional reconceptualization of vaginismus.

    The progression of certain primary esophageal motor disorders to achalasia has been documented; however, the true incidence of this decay is still elusive. This study aims to evaluate: (i) the incidence of the progression of diffuse esophageal spasm to achalasia, and (ii) predictive factors to this progression. Thirty-five patients (mean age 53 years, 80% females) with a manometric picture of diffuse esophageal spasm were followed for at least 1 year. Patients with gastroesophageal reflux disease confirmed by pH monitoring or systemic diseases that may affect esophageal motility were excluded. Esophageal manometry was repeated in all patients. Five (14%) of the patients progressed to achalasia at a mean follow-up of 2.1 (range 1-4) years. Demographic characteristics were not predictive of transition to achalasia, while dysphagia (P= 0.005) as the main symptom and the wave amplitude of simultaneous waves less than 50 mmHg (P= 0.003) were statistically significant. In conclusion, the transition of diffuse esophageal spasm to achalasia is not frequent at a 2-year follow-up. Dysphagia and simultaneous waves with low amplitude are predictive factors for this degeneration. © 2012 Copyright the Authors.

    Full Text Available Resting-state functional magnetic resonance imaging (fMRI has been used to detect the alterations of spontaneous neuronal activity in various neurological and neuropsychiatric diseases, but rarely in hemifacial spasm (HFS, a nervous system disorder. We used resting-state fMRI with regional homogeneity (ReHo analysis to investigate changes in spontaneous brain activity of patients with HFS and to determine the relationship of these functional changes with clinical features. Thirty patients with HFS and 33 age-, sex-, and education-matched healthy controls were included in this study. Compared with controls, HFS patients had significantly decreased ReHo values in left middle frontal gyrus (MFG, left medial cingulate cortex (MCC, left lingual gyrus, right superior temporal gyrus (STG and right precuneus; and increased ReHo values in left precentral gyrus, anterior cingulate cortex (ACC, right brainstem, and right cerebellum. Furthermore, the mean ReHo value in brainstem showed a positive correlation with the spasm severity (r = 0.404, p = 0.027, and the mean ReHo value in MFG was inversely related with spasm severity in HFS group (r = -0.398, p = 0.028. This study reveals that HFS is associated with abnormal spontaneous brain activity in brain regions most involved in motor control and blinking movement. The disturbances of spontaneous brain activity reflected by ReHo measurements may provide insights into the neurological pathophysiology of HFS.

    Combined radiobronchological examination of patients with chronic pneumonia in the phase of reverse development of the disease has been performed. Severity, localization and extent of bronchial obstruction have been studied, depending on the phase of chronic pneumonia and aspects of lung tissue alterations. Bronchial lesions characteristic of chronic pneumonia were defined, as well as importance of x-ray examination methods for bronchial obstruction diagnosis. Three types of bronchial obstruction were distinguished: bronchoconstriction, bronchodilatation and their combination. With regard to the character and severity of bronchial and pulmonary tissue lesions 3 variants of chronic pneumonia are offered to be differentiated: bronchitic, bronchoectatic, and abscess-forming. The main significance in diagnosis of chronic pneumonia is attributed to combined x-ray examination, which also includes radiobronchological investigation in the first two variants of the disease [ru

    1982-01-01

    In 97 patients with bronchitis, bronchial asthma, tuberculosis, sarcoidosis, pneumoconiosis, or tumors the mucociliary clearance and/or deposit pattern after inhalation of radioactively marked aerosols (1 mCi 99m Tc sulfur colloid) was studied. Normal values of the mucociliary 30 min. clearance for the central bronchial/lung periphery are 21%/15%. There was a decreased clearance with bronchitis (11/8%), bronchial asthma, emphysema, tuberculosis, sarcoidosis, trachiobronchial amyloidosis, pleural scarring or interstitial pneumona. Increased clearance (29/19%) was shown with pneumoconiosis. The correlation of deposit pattern and disease, for example, bronchitis, bronchial asthma, bullous emphysema, pleural scarring, partial lung resection, bronchopneumonia, or bronchial restriction, is described. In comparison of aerosol scintigraphy to perfusion scintigraphy and ventilation with gaseous xenon, the aerosol scintigraphy is superior to xenon for certain indications. The aerosol particles, which are larger in comparison to xenon, settle easier by obstructions or flow variations and thereby give better clinical indications of regional differences. (orig.) [de

    The classic auscultation with stethoscope is the established clinical method for the detection of lung diseases. The interpretation of the sounds depends on the experience of the investigating physician. Therefore, a new computer-based method has been developed to classify breath sounds from digital lung sound recordings. Lung sounds of 11 patients with one-sided pneumonia and bronchial breathing were recorded on both the pneumonia side and on contralateral healthy side simultaneously using two microphones. The spectral power for the 300-600 Hz frequency band was computed for four respiratory cycles and normalized. For each breath, the ratio R between the time-segments (duration = 0.1 s) with the highest inspiratory and highest expiratory flow was calculated and averaged. We found significant differences in R between the pneumonia side (R = 1.4 +/- 1.3) and the healthy side (R = 0.5 +/- 0.5; p = 0.003 Wilcoxon-test) of lung. In 218 healthy volunteers we found R = 0.3 +/- 0.2 as a reference-value. The differences of ratio R (delta R) between the pneumonia side and the healthy side (delta R = 1.0 +/- 0.9) were significantly higher compared to follow-up studies after recovery (delta R = 0.0 +/- 0.1, p = 0.005 Wilcoxon-test). The computer based detection of bronchial breathing can be considered useful as part of a quantitative monitoring of patients at risk to develop pneumonia.

    Bronchial asthma is a clinical syndrome with possible correlation to oxidative stress, therefore the effectiveness of some antioxidant drugs has been studied in management of chronic bronchial asthma. Methods: This study was carried out in the Al- Kadhimia Teaching Hospital between December 2008 to May 2009 on 56 patients of both sexes who were randomly allocated to 7 groups, plus 10 healthy volunteers as control group. Each group was given one of the following drugs: vitamin E, vitamin C, combination of vitamin E and C, selenium, zinc, allopurinol and garlic oil, in addition to their classical treatment of asthma and their pulmonary function tests were conducted as well as measuring the levels of serum zinc, calcium, and malondialdehyde (MDA) before and after treatment. Results: All asthmatic patients were suffering from oxidative stress and this was detected by measuring the level of serum MDA which was 2-3 folds more than the control group, and all antioxidants except allopurinol showed a beneficial effect of different degrees in the pulmonary function tests accompanied with clinical improvement of patients' condition and marked decrease in the number of daily attacks. Antioxidants can compensate the oxidative stress that correlates with asthma, can reduce the symptoms of asthma, and improve pulmonary functions. (author)

  10. Metastatic urachal carcinoma in bronchial brush cytology

    2013-01-01

    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.

    Celiac disease is an immune-mediated disorder elicited by ingestion of gluten in genetically susceptible persons. This disorder is characterized by specific histological changes of the small intestine mucosa resulting in malabsorption. This case was written up as it was an unusual and dramatic presentation of celiac disease. We report the case of a 3-year-old Albanian girl who presented at our clinic with carpal spasms and hand paresthesia. A physical examination at admission revealed a relatively good general condition and body weight of 10.5 kg (10 percentile). Carpal spasms and paresthesias of her extremities were present. Neuromuscular irritability was demonstrated by positive Chvostek and Trousseau signs. Blood tests showed severe hypocalcemia with a total serum calcium of 1.2 mmol/L (normal range 2.12 to 2.55 mmol/L), ionized calcium of 0.87 (normal range 1.11 to 1.30 mmol/L), and 24-hour urine calcium excretion of 9.16 mmol (normal range female celiac disease was performed: antigliadin immunoglobulin A, anti-tissue transglutaminase, and anti-endomysial immunoglobulin A antibodies were positive. A duodenal biopsy revealed lymphocyte infiltration, crypt hyperplasia, and villous atrophy compatible with celiac disease grade IIIb according to the Marsh classification. Following the diagnosis of celiac disease, human leukocyte antigen typing was performed, giving a definite diagnosis of celiac disease. She was started on a gluten-free diet. Due to failure to follow a gluten-free diet, episodes of carpal spasms appeared again. Unfortunately, at the age of 7 years she presents with delayed psychophysical development. Although hypocalcemia is a common finding in celiac disease, hypocalcemic carpal spasm is a rare initial manifestation of the disease. Therefore, the possibility of celiac disease should be considered in patients with repeated carpal spasms that seem unduly difficult to treat. This should be evaluated even in the absence of gastrointestinal

    Objective To determine the frequency of mutations in CDKL5 in both male and female patients with infantile spasms or early onset epilepsy of unknown cause, and to consider whether the breadth of the reported phenotype would be extended by studying a different patient group. Methods Two groups of patients were investigated for CDKL5 mutations. Group 1 comprised 73 patients (57 female, 16 male) referred to Cardiff for CDKL5 analysis, of whom 49 (42 female, 7 male) had epileptic seizure onset in the first six months of life. Group 2 comprised 26 patients (11 female, 15 male) with infantile spasms previously recruited to a clinical trial, the UK Infantile Spasms Study. Where a likely pathogenic mutation was identified, further clinical data were reviewed. Results Seven likely pathogenic mutations were found among female patients from group 1 with epileptic seizure onset in the first six months of life, accounting for seven of the 42 in this group (17%). No mutations other than the already published mutation were found in female patients from group 2, or in any male patient from either study group. All patients with mutations had early signs of developmental delay and most had made little developmental progress. Further clinical information was available for six patients: autistic features and tactile hypersensitivity were common but only one had suggestive Rett‐like features. All had a severe epileptic seizure disorder, all but one of whom had myoclonic jerks. The EEG showed focal or generalised changes and in those with infantile spasms, hypsarrhythmia. Slow frequencies were seen frequently with a frontal or fronto‐temporal predominance and high amplitudes. Conclusions The spectrum of the epileptic seizure disorder, and associated EEG changes, in those with CDKL5 mutations is broader than previously reported. CDKL5 mutations are a significant cause of infantile spasms and early epileptic seizures in female patients, and of a later intractable seizure disorder

    We investigated the clinical situations and the present knowledge of Japanese cardiologists about coronary artery spasm before and after the establishment of guidelines for this condition in the real world. A questionnaire was developed regarding the number of cases of coronary angiography, percutaneous coronary intervention, and invasive/non-invasive spasm provocation tests before (2008) and after (2014) the establishment of the Japanese Circulation Society (JCS) guidelines for coronary artery spasm and the status of spasm provocation tests. The questionnaire was sent to members of the Japanese Cine-angio Association in 81 cardiology hospitals in Japan. The completed surveys were returned from 20 hospitals, giving a response rate of 24.7%. Pharmacological spasm provocation tests increased in 2014 and vasospastic angina and variant angina also increased in 2014 compared with 2008, but the increase was not significant. Non-invasive spasm provocation tests such as hyperventilation tests and cold stress tests decreased remarkably in 2014. Spasm provocation tests were initially performed in the left coronary artery was employed in just 30% of the hospitals. The majority of institutions did not perform the spasm provocation testing in patients with unknown causes of heart failure or in survivors of ventricular fibrillation. Although 40% of the hospitals were not satisfied with standard spasm provocation tests, the majority of the hospitals agreed that spasm provocation tests will be necessary in the future. In general, the JCS guidelines contributed to the widespread use of provocative testing for coronary artery spasm in the real world. However, some issues about spasm still remained in the clinic.

    Objective: To evaluate the pulmonary metastatic tumor response to different ways of transcatheter arterial infusion. Methods: Thirty-five patients with pulmonary metastatic tumors were randomized divided into two groups: 15 patients with 49 lesions treated with bronchial arterial infusion (BAI) and 20 patients with 65 lesions treated with bronchial arterial infusion (BM)combined with pulmonary arterial infusion (PAI). The therapeutic response was assessed by the WHO evaluation criteria. Results: The total effective rate(CR + PR) of BAI was 65.3% (32/49), PAI + BAI was 61.5%(40/65) showing no statistical difference. The median survival time of BAI was 9 mo, BAI + PAI was 11.5 mo, demonstrating no statistical significance. Conclusions: BAI should be the primary treatment for pulmonary metastatic tumor. (authors)

    Full Text Available The effect of inhalation of ipratropium bromide was evaluated in 20 patients with bronchial asthma. It was observed that there was no significant improvement in the forced vital capacity and the forced expired volume in one second, while there was significant improvement in the peak expiratory flow rate (PEFR measured at 9 pm, after inhalation of 2 puffs of ipratropium bromide aerosol (0.02mg/puff three to four times a day for 2 weeks. Since PEFR is a measure of large airway function and cholinergic mechanisms are primarily involved for airflow obstruction at large airways, improvement in PEFR by ipratropium bromide highlights its role as a useful bronchodilator in patients in whom vagal reflexes are responsible for the provocation of bronchoconstriction.

    Asthma and COPD (chronic obstructive pulmonary disease) are the most important obstructive pulmonary diseases. Patient's history and physical evaluation give major hints of the underlying disease. Further diagnostic measures comprise lung function analysis including spirometry, plethysmography and--in severe cases--blood gas analysis. Bronchial hyperreactivity may be quantified with an unspecific inhalative provocation test. In many cases allergic diseases are accompanied by asthma. Thus, allergy tests--particularly skin prick tests--have to be carried out. To further define an underlying allergy, in some cases even specific inhalative provocation tests have to be performed. X-ray of the thorax and other imaging techniques, detailed blood analysis, further diagnosis of the upper respiratory tract and the cardiac system may have to be carried out a) to quantify the effects of a severe form of asthma or COPD on other organs, and b) for differential diagnostic examinations.

    Bronchial rupture is a rare and serious complication of blunt chest trauma in children. The diagnosis of this injury is challenging and requires a high degree of clinical suspicion. It is frequently associated with other severe injuries that may draw the focus of attention away from this potentially catastrophic but treatable injury. The radiographic findings of bronchial rupture have been reported in very few series. We report the findings in two children with bronchial rupture diagnosed by CT, in whom CT resulted in a significant change in patient management. (orig.)

    Objective: To investigate the safety and the effect of superselective bronchial artery chemoembolization in the treatment of lung cancer. Methods: Three hundred and twenty-nine cases of lung cancer diagnosed by pathology and treated with simply bronchial artery infusion or superselective bronchial artery chemoembolization were investigated. (1) Simply bronchial artery infusion (n=221): 40-60 mg Cisplatin or 200-300 mg Carboplatin combined with 10-20 mg Mitomycin-C or 100-200 mg Etoposide were infused through the catheter which was placed in the bronchial artery trunk or intercostal-bronchial artery trunk after angiography, re-infusion was performed at 2-4 weeks intervals, 549 times of infusion were performed in 221 cases. (2) Superselective bronchial artery chemoembolization (n=108): microcatheter was superselectively inserted into the distal of feeding artery guided with road-map after selective angiography, then anticarcinogen (same as simply bronchial artery infusion) and embolic material were infused through microcatheter. 30-50 Gelfoam particles and/or 3-8 ml Lipiodol was used as embolic material. Chemoembolization was reperformed at 6-9 weeks intervals, 266 times of chemoembolization were done in 108 cases. Results: No severe complications such as spinal injury were found. 28 cases in 221 cases performed with simply bronchial infusion got complete response (CR), meanwhile, partial response (PR) in 79 cases, stable(S) in 88 cases, and processes (P) in 26 cases. The effective rate (CR + PR) was 48.4%, survival rate of 1 year and 2 years were 53.8% and 44.8%, respectively. In the 108 cases performed with superselective bronchial artery chemoembolization, there were 16 cases of CR, 53 cases of PR, 32 cases of S, and 7 cases of P. The effective rate (CR + PR) was 63.9%, survival rate of 1 year and 2 years were 77.8% and 65.7%, respectively. There were significant statistic differences in the effective rate and survival rate of 1 year and 2 years between the two

    Full Text Available Introduction: Neuromodulation in its various forms is emerging as a promising method of dealing with chronic pain and movement disorders. The scale of ablative vs augmentative procedures seems to be tilting towards augmentative procedures. We observed 8 patients who had failed medical treatment for muscle spasm respond to the cold application. Case summary: We report 2 cases of complete traumatic spinal cord injury patients, who developed severe, medically intractable muscle spasms. We applied cryotherapy to their legs with significant improvement. Outcome measurements: The spasm frequency score dropped immediately from a 4 to 0 in one patient. The other dropped from a 2 to 1 on day one then disappeared by day 7. Spasm severity dropped significantly on the first day in both cases. Conclusion: Cryotherapy as a form of neuromodulation, Is an effective, simple but safe way to symptomatically manage severe medically refractory muscle spasms in spinal cord injured patients. It becomes an important adjunct in the management of these patients in resource-limited settings where surgical options are not readily available.

IS is often difficult to manage 'With the usual anti-epilepsy drugs (AEDs. Therapy with adrenocorticotropin honnone (ACTH has been used since 1958. In Indonesia, ACTH usage is still rare. Objective This study aims to examine the effectiveness of ACTH as an anti-epileptic drug in managing IS. Methods This was descriptive retrospective cohort study. Subjects were IS patients who visited the neurology outpatient clinic in Sanglah Hospital, Bali, from January 2007 until June 2010. Each subject received AED(s plus either ACTH or methylprednisolone for 46 weeks. Results There were 19 IS patients over the four year duration of this study. They were mostly boys (11, aged 2 weeks to 17 months, with a mean age at treatment of 9 months. Eighteen patients received poly therapy, while one patient received only phenobarbital as monotherapy. Most patients who received ACTH (13/16 had a seizure-free period, while the 3 that did not receive ACTH continued having seizures. Patients who received ACTH showed a good response (seizure-free after 5-13 days therapy and their EEG pattern showed disappearance of burst suppression Mthin 1-2 weeks. ACTH side effects included weight gain and cushingoid appearance. One patient died from pneumonia. Conclusions Diagnosis of IS should be considered in patients pre-senting Mth spasms at less than 6 months old. IS treatment should begin as soon as possible. IS patients responded well to a short course of ACTH therapy.

    Bronchial artery embolization is now a common treatment for massive pulmonary hemoptysis if flexible bronchoscopy at the bedside failed to control the bleeding. Complications of this technique range from benign chest pain to devastating neurological impairments. We report the case of a 41-year-old man who developed an ST elevation myocardial infarction during bronchial artery embolization, presumably because of coronary embolism by injected particles. In this patient who had no previously known coronary artery disease, we retrospectively found a communication between the left bronchial artery and the circumflex coronary artery. This fistula was not visible on the initial angiographic view and likely opened because of the hemodynamic changes resulting from the embolization. This case advocates for careful search for bronchial-to-coronary arterial fistulas and the need for repeated angiographic views during embolization procedures.

    A 70-year-old man with recurrent undiagnosed episodes of bronchial cast expectoration and pulmonary infiltrates on chest radiography for 15 years is described. The diagnosis of chyloptysis was established by chemical analysis of the bronchial aspiration. We emphasize the radiological findings of this rare observation. The CT-associated lymphangiography showed mediastinal lymphangiectasis with retrograde opacification of mediastinal and hilar lymph nodes as well as submucosal lymphatic vessels protruding into the lumen of the tracheo-bronchial tree without evidence of thoracic duct obstruction as well as a ''crazy-paving appearance.'' Congenital incompetence of the valves of the lymphatic vessels originating from the thoracic duct is held to be the cause. Chyloptysis and pulmonary lymphatic disorder should be sought in cases of bronchial cast expectoration. (orig.)

    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.)

    Objective was to evaluate the efficacy of bronchial arteriography and bronchial artery embolization (BAE) in the management of massive hemoptysis in a developing Asian country. A retrospective review was carried out from March 2000 to March 2005 to evaluate the demographics, clinical presentation, radiographic studies, bronchoscopy results, and complications of bronchial arteriography and BAE at a tertiary care hospital in Pakistan. Fourteen patients (9males, 5 females) with a mean age of 49 years underwent bronchial arteriography and BAE for massive hemoptysis. Hemoptysis was caused by bronchiectasis (10 patients), active pulmonary tuberculosis (3 patients), and lung malignancy (one patient). A CT scan of the chest was carried out in 11 patients, which revealed bronchiectasis (8 patients), cavity with infiltrates (3 patients), and mass lesion (one patient). Bronchoscopy was performed in all patients. Bleeding lobe or segment was identified in 12 patients. Bronchial arteriography revealed hypervascularity (13 patients), bronchial artery hypertrophy (5 patients), hypervascularity with shunting (one patient), dense soft tissue staining (7 patients), extravasation of contrast (one patient) pseudoaneurysm (one patient). Bronchial artery embolization was carried out in all patients. Rebleeding occurred within 24 hours in 2 patients who underwent surgery and within one week another 2 patients who were managed with repeat BAE. The complication of embolization occurred in one patient (transverse myelitis). Thirteen patients improved and were discharged home. One patient with terminal lung carcinoma died due to cardiogenic shock secondary to acute myocardial infarction. Bronchial artery embolization is an effective method for management of massive hemoptysis in developing countries and has a low complication rate. (author)

    We studied the effects of aerosolized as well as intravenous infusion of acetylcholine on bronchial blood flow in six anesthetized sheep. Intravenous infusion of acetylcholine, at a dose of 2 microg/kg, increased bronchial blood flow from 45 +/- 15 (SE) to 74 +/- 30 ml/min, and vascular conductance increased by 76 +/- 22%. In contrast, aerosolized acetylcholine at doses of 2 and 20 microg/kg decreased bronchial vascular conductance by approximately 10%. At an aerosolized dose of 200 microg/kg, the bronchial vascular conductance increased by approximately 15%, and there was no further increase in conductance when the aerosolized dose was increased to 2,000 microg/kg. Pretreatment of animals with a nitric oxide synthase inhibitor, Nomega-nitro-L-arginine methyl ester hydrochloride, partially blocked the vasodilatory effects of intravenous acetylcholine and completely blocked the vasodilatory effects of high-dose aerosolized acetylcholine. These data suggest that aerosolized acetylcholine does not readily penetrate the vascular wall of bronchial circulatory system and, therefore, has minimal vasodilatory effects on the bronchial vasculature.

    Full Text Available   Introduction: To assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   Materials and Methods: A retrospective study on 46 patients (26 males and 20 females who were referred to the Razavi Hospital from April 2009 to May 2012 with massive hemoptysis and had bronchial artery embolization procedures. 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.

    Hemifacial spasm (HFS) is characterized by involuntary, irregular clonic or tonic movement of muscles innervated by the facial nerve. We evaluated structural reorganization in brain gray matter and white matter and whether neuroplasticity is linked to clinical features in HFS patients. High-resolution structural magnetic resonance imaging and diffusion tensor imaging data were acquired by 3.0 T MRI from 42 patients with HFS and 30 healthy subjects. The severity of the spasm was assessed according to Jankovic disability rating scale. Voxel-based morphometry (VBM) and tract-based spatial statistics (TBSS) analysis were performed to identify regional grey matter volume (GMV) changes and whole-brain microstructural integrity disruption measured by fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD). The VBM analysis showed that patients with HFS reduced GMV in the right inferior parietal lobule and increased GMV in the cerebellar lobule VIII, when compared with healthy subjects. Furthermore, within the HFS disease group, GMV decreased with the disease duration in the right inferior parietal lobule. TBSS did not identify group differences in diffusivity parameters. While no white matter integrity disruption was detected in the brain of patients with HFS, our study identified evident GMV changes in brain areas which were known to be involved in motor control. Our results suggest that HFS, a chronic neurovascular conflict disease, is related to structural reorganization in the brain. Copyright © 2015 International Federation of Clinical Neurophysiology.

    Bupivacaine is a long-acting local anesthetic (LA) used for cutaneous infiltration, peripheral nerve blocks, epidural and spinal anesthesia. However, its application may result in cardiovascular complications such as: hypotension, bradycardia, cardiac arrest and toxic myocardial injury. The authors describe a 53-year-old male with a history of cigarette smoking, admitted for an elective inguinal hernia surgery. Before surgery, the patient received subarachnoid injection of bupivacaine (20 mg). After the operation, he developed transient hypotension. Blood pressure returned to normal after gelofusine infusion; no sympathomimetics were administered. The male denied chest pain; however, ECG showed ST segment elevation coexisting with left ventricular anterolateral hypokinesia and decreased longitudinal strain in echocardiography. A significant increase in troponin I level was suggestive rather of myocardial infarction than of takotsubo cardiomyopathy. Urgent coronary angiography revealed left anterior descending artery spasm, which remitted after intracoronary nitroglycerin injection. Normalization of ECG and echocardiography was observed within a few days. The authors indicate that the presented atypical adverse effect of bupivacaine manifested itself with delay and that coronary spasm proceeded without angina. A close observation of the patient after anesthetic procedure with LA should be extended over the postoperative period.

    Cocaine is a frequently used recreational drug which imposes important health problems with even life-threatening cardiotoxicity. The therapeutic use of cocaine is nowadays restricted to topical anesthesia in ophthalmological and nasal surgery but the possible hazards of this local anesthesia are not always fully appreciated. A 51-year old male patient with moderate cardiovascular risk profile underwent elective nasal surgery and cocaine was used as a local anesthetic. During surgery, ventricular arrhythmias and cardiogenic shock occurred, mimicking an ST-segment elevation myocardial infarction (STEMI) in sinus rhythm. Coronary angiography showed diffuse spasm of the right coronary artery (RCA) which disappeared with intracoronary nitrates. Urine analysis was positive for cocaine. The patient recovered completely with a normal echocardiography and ECG at discharge. Cocaine cardiotoxicity is not uncommon in the community but a particular situation arises when used in medicine as a topical anesthetic. This is the first case report, to our knowledge, of a cardiogenic shock mimicking a STEMI with documentation of diffuse coronary spasm after cocaine use in nasal surgery. One must be aware of the potential life-threatening complications in this low-risk surgery, moreover when safer alternatives are available.

    Full Text Available We report the case of an emmetropic 32-year-old female with decreased uncorrected visual acuity and diplopia due to intermittent episodes of spasm of the near reflex. Neurologic, general, and ophthalmic examination could not find an organic cause. Attempts at spontaneous recovery, psychogenic therapy, and cycloplegic therapy were unsuccessful and the symptoms persisted for almost 5 years, leading to psychogenic distress. Final treatment with refractive lens exchange and implantation of a toric trifocal intraocular lens resolved the spasm of the near reflex, resulting in an uncorrected distance and near visual acuity of 20/20.

    We assessed the ability of visualization of bronchial artery (BA) by using thin-slice axial images of 4-detector multidetector row CT in 65 patients with hemoptysis. In all patients, the origins of BA were well identified with observation of consecutive axial images with 1 mm thickness by paging method and bronchial arterial embolization (BAE) was performed successfully. Thin-slice axial images were considered to be useful to recognize BA and to perform BAE in patients with hemoptysis. (author)

    Comparative studies were made of 47 patients suffering from histologically and cytologically confirmed bronchial carcinoma, using CT and MRT respectively. CT examinations were performed before and after intravenous administration of contrast medium, whereas the MR examinations were conducted via EEG-triggered T 1 and T 2 marked SE sequences in the axial and coronary planes. Both methods were assessed in respect of tumour visualisation and documentation of tumour spread. Staging of tumour and lymph nodes yielded largely concurring results for CT and MRT. Exceptions were seen in 7 of 10 patients with malignant involvement of the pericardium and in 3 of 27 patients with lymph node metastases located mediastinally and subcarinally where only MRT showed a positive involvement of the pericardium or lymph nodes (with possible consequences for the staging of the tumour or lymph nodes). Decisive advantages of MRT compared with CT were seen in the identification of infiltration of the aortic-wall, in the differentiation of the poststenotic syndrome, in the visualisation of the thoracic wall infiltration and functional information on blood flow rate in upper venolus obstruction caused by a carcinoma.

    We evaluated the longitudinal changes in lung function and the factors associated with FEV(1) changes over time in a sample of asthmatic subjects. FEV(1) measures were recorded every 3 months over a 5-year follow-up period. To compare all subjects independently of body size, FEV(1) values were normalized for the subject's height at the third power. We evaluated the possible effect of age, baseline FEV(1), disease duration, and FEV(1) variability on the rate of change of FEV(1). We studied 142 subjects with asthma diagnosed on the basis of validated clinical and functional criteria. FEV(1) showed a linear decay with aging in each subject. For a subject 1.65 m in height, the median overall FEV(1) decay was 40.9 mL/yr. FEV(1) decay slopes were significantly influenced by age and sex, being steeper in younger male subjects. A significant interaction was found between age and baseline FEV(1): the FEV(1) decay was significantly higher among younger asthmatics with a poorer baseline functional condition. A longer disease duration was associated with a lower FEV(1) slope. FEV(1) variability was strongly associated with an increased rate of FEV(1) decline. FEV(1) decline in patients with bronchial asthma is significantly influenced by baseline FEV(1), disease duration, and FEV(1) variability. Moreover, the rate of FEV(1) decline seems to increase in younger subjects only when the baseline function is poorer.

    Mucociliary clearance was measured in 19 healthy non-smoking male subjects, aged between 21 and 69, by analysing the decrease in bronchial radioactivity of an aerosol of resin particles (mean diameter 7.4 +- 1.5 μm) labelled with sup(99m)Tc. The mucociliary clearance was expressed as the percentage of radioactivity eliminated after 1 h. The measurements were made on two occasions with an average time lapse of 5 weeks. The intra- and inter-individual coefficients of variation were 15.6% and 41.5% respectively. The mucociliary clearance was significantly lower (P 54 years) than that observed (mean 34.1 +- s.d. 14.1%) in the younger subjects (21 to 37 years). A significant negative correlation (r=-0.472, P<0.05) was obtained between the ages of the healthy subjects and their mucociliary clearance. However, the fact that the results varied considerably within each age group suggests that factors other than age may have an effect on the mucociliary clearance. (author)

    Full Text Available The study involved 30 students with severe bronchial asthma and 30 children with moderate to severe course. Patients with severe bronchial asthma revealed a clear tendency to increase the relative content of interleukin 4 in peripheral blood, which indirectly indicates the severity of inflammation in the bronchi. Almost every second child suffering from severe bronchial asthma reported an increase in the concentration of immunoglobulin E (more than 545.3 IU/ml, and the odds ratio was 1.9 (95% CI 1.1–3.4. In the group of patients with severe bronchial asthma, cases of increased skin sensitivity to household allergens were significantly more frequent compared to the second group. Thus, the size of hyperemia over 15.0 mm was recorded in 81.5 % of children of the first group and only in 51.9 % of persons (Pϕ < 0.05 in the second one. Clinical and epidemiological risk and diagnostic value of individual indicators of atopic reactivity were determined to verify the phenotype of severe bronchial asthma.

    Full Text Available Background. The importance of psychosocial factors in the management of bronchial asthma (BA is discussed in clinical guidelines, including in international and national clinical guidelines. However, a specific evaluation of their role as a cause of poor asthma control in susceptible patients is required. Aim. Assessment of psychological health of women with different levels of asthma control.Materials and methods. The study included 108 women with asthma observed in Saratov center for Allergology who were stratified into 3 groups according to the control level (good, partial, uncontrolled, according to GINA. In establishing a diagnosis of asthma, standard methods were used (medical history, symptoms, spirography. To assess the level of control, ACQ-5 (Asthma Control Questionnaire 5 items-self-administered was used, to assess the quality of life, questionnaires AQLQ-S (Asthma Quality of Life Questionnaire S; SF-36 (36-ltem MOS Short-Form Health Survey, a standardized and validated Russian version of the women’s health questionnaire WHQ (Women’s Health Questionnaire were used; for psychological diagnosis and evaluation of social and personal competencies that contribute to the preservation and improvement of human health (the intellectual, personal, emotional, physical, social, creative, spiritual aspects, integrated multimodal questionnaire was used. The comparison was conducted with a control group of men with bronchial asthma, comparable in age and level of control.Results. Women with poorly controlled asthma had worse performance of AQLQ-S (combined median score of 3,43 instead of 5,13 in the group of good control; p < 0,05; all scales of the SF-36, including the general condition (43,48 against 55,07, role of physical (25,93 against 57,76 and emotional problems (43,83 against 64,37; at p < 0.05.

    From the paediatric point of view, we have undertaken two Delphi studies into bronchial asthma. The first is related to the consensus known as the consensus document of the five associations. The second is more recent and has been undertaken with GEMA (the Spanish Guidelines on the Management of Asthma). The aim of this paper is to carry out a descriptive study comparing the 2 Delphi processes and to objectively assess if in some way behaviour over the past two years has changed as far as expert opinion is concerned. In the consensus document those points giving rise to most controversy were the treatment of children under three years of age and treatment with immunotherapy in allergic asthma. It is also necessary to highlight how important it was at that particular point in time to define the phenotypes of wheezing and the predictive index of asthma in children of less than 3 years of age. Of the 52 questions in the questionnaire, in 13.6% the panel of experts reached no consensus in their positions. Following GEMA the Delphi methodology, 56 questions were asked in the first round of the questionnaire, and consensus was reached in 87.5%. As regards the paediatric part relating to diagnosis and treatment in children, agreement was reached on all the questions in the first round. Agreement was reached in 8.92% questions in the second round. Clinical guidelines and consensus documents can modify behaviour towards an illness, both in the diagnosis and treatment.

    Tonic spasms (TS) are involuntary movement patterns that can present in patients with multiple sclerosis (MS). They have been first described decades ago, but are frequently missed and misdiagnosed, particularly in the pediatric MS patients and if appearing ahead of hallmark neurological signs and symptoms of MS. Slovenia is a country with the population of about 2 million people. In the years from 1992 to 2016, we have treated 57 sequential pediatric patients with MS at our hospital, which is the only tertiary medical institution for treating children with MS in the country. We present the only two MS patients, a 17-year-old girl and a 14-year-old boy, whose first manifestation of MS were TS. This allowed us to estimate the incidence of TS in pediatric MS patients in Slovenia. Copyright © 2017 Elsevier B.V. All rights reserved.

    Since the pharynx and the esophagus are a functional unit, functional radiodiagnosis has to be directed at pharyngo-esophageal interaction. Among our collective of 73 patients suffering from achalasia or diffuse esophageal spasm, we were able to recognize a substantially increased incidence of morphological or functional pharyngeal disorders by means of cineradiography. The functional alterations in particular were often not revealed by conventional fluoroscopy. High-speed cineradiography, with its high temporal and spatial resolution, turned out to be a valuable tool in analysis of the origin of pharyngeal dysphagia. Manometry correlated very well with the radiologic findings in tubular esophagus, but proved unreliable in the detection of alterations of the upper esophageal sphincter region, because of problems inherent in the method. Furthermore, membranous stenosis (webs), lateral or dorsal diverticula, and asymmetry of the pharynx were observed strikingly often. (orig.).

    Cardiopulmonary resuscitation guidelines imply the use of epinephrine/adrenaline during cardiopulmonary arrest. However, in cardiac arrest situations resulting from coronary artery spasm (CAS), the use of epinephrine/adrenaline could be deleterious. A 49-year-old patient underwent an emergency coronarography with an attempt to stent the coronary arteries. Radiologic imaging revealed a positive methylergonovine maleate (Methergine, Novartis Pharmaceuticals, East Hanover, NJ) test, with subocclusive CAS in several coronary vessels leading to electromechanical dissociation. Cardiopulmonary resuscitation was performed, and intracoronary boluses of isosorbide dinitrate were given to treat CAS. Epinephrine/adrenaline was not administered during resuscitation. Spontaneous circulation was obtained after cardioversion for ventricular fibrillation, and the patient progressively regained consciousness. Resuscitation guidelines do not specify the use of trinitrate derivatives in cardiac arrest situations caused by CAS. The pros and cons of the use of nitrates and epinephrine/adrenaline during cardiac arrest caused by CAS are analyzed in this case report.

    Full Text Available Mood, anxiety and other psychological symptoms are common in dystonic patients suffering from blepharospam (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 (SFI, a reduced form of the Gollombok 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.

    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.

  12. Altered Default Mode Network on Resting-State fMRI in Children with Infantile Spasms

    Full Text Available Infantile spasms (IS syndrome is an age-dependent epileptic encephalopathy, which occurs in children characterized by spasms, impaired consciousness, and hypsarrhythmia. Abnormalities in default mode network (DMN might contribute to the loss of consciousness during seizures and cognitive deficits in children with IS. The purpose of the present study was to investigate the changes in DMN with functional connectivity (FC and amplitude of low-frequency fluctuation (ALFF, the two methods to discover the potential neuronal underpinnings of IS. The consistency of the two calculate methods of DMN abnormalities in IS patients was also our main focus. To avoid the disturbance of interictal epileptic discharge, our testing was performed within the interictal durations without epileptic discharges. Resting-state fMRI data were collected from 13 patients with IS and 35 sex- and age-matched healthy controls. FC analysis with seed in posterior cingulate cortex (PCC was used to compare the differences between two groups. We chose PCC as the seed region because PCC is the only node in the DMN that directly interacts with virtually all other nodes according to previous studies. Furthermore, the ALFF values within the DMN were also calculated and compared between the two groups. The FC results showed that IS patients exhibited markedly reduced connectivity between posterior seed region and other areas within DMN. In addition, part of the brain areas within the DMN showing significant difference of FC had significantly lower ALFF signal in the patient group than that in the healthy controls. The observed disruption in DMN through the two methods showed that the coherence of brain signal fluctuation in DMN during rest was broken in IS children. Neuronal functional impairment or altered integration in DMN would be one neuroimaging characteristic, which might help us to understand the underlying neural mechanism of IS. Further studies are needed to determine whether

    Bronchial foreign bodies by children are dangerous and require immediate therapeutic measures. Findings and significance of chest film in the diagnosis of bronchial foreign bodies in 24 children were analysed. All patients were symptomatic. 18 patients had an abnormal and 6 normal auscultation finding. In three cases the physician did not suspect aspiration, and the diagnosis was delayed, which caused the death of one child. Roentgenpositive foreign bodies were found in 8 and -negative in 16 cases. Secondary changes (obstructive emphysema, atelectasis, pneumonia) were seen in 16 cases. In emergency cases the chest films were analysed by physician and later by a radiologist, who found 88% of them to be abnormal. Fluoroscopy of expiratory chest film helps to detect the unilateral emphysema more distinctly. The diagnosis must always be confirmed with bronchoscopy and extraction thereby is the adequate treatment of bronchial bodies. (orig.) [de

    Full Text Available Antibodies to IgE are a totally new class of medications currently used to enhance the supervision over severe persistent atopic bronchial asthma. Omalizumab is the most well studied, first and only medication of this group, which is recommended for the application and is allowed for treatment of uncontrolled bronchial asthma among adults and children aged 12 and over in different countries of the world, including Russia. High omalizumab assisted treatment costs, as well as the need in the monthly visits to the doctor for the omalizumab injections are justified for the patients, requiring repeat hospitalizations, emergency medical aid, using high doses of the inhalation and/or systemic glucocorticosteroids. The article reviews the criteria for the selection of patients fit for omalizumab assisted treatment.Key words: omalizumab, anti-ige-antibodies, bronchial asthma, allergic rhinitis, treatment, children.

    Full Text Available The effi ciency of lung transplantation is considerably limited by the complications associated with the bronchial pathologies. Despite the progress of the treatment methods, bronchial complications are still remaining as an actual problem in the postoperative period with frequency of occurrence from 7 to 29%. However, the bronchial stenosis are the most common bronchial complications after lung transplantation with mortality from 2 to 4%.Aim. To study an experience of our center of bronchial stenosis treatment in lung recipients. Materials and methods. 34 patients underwent lung transplantation from September 2014 to January 2017. 6 (16% of them had a stenosis of lobar or segmental bronchi from 84 to 494 postoperative day. 5 (83% of them have demonstrated multifocal lesions. In all of the cases there was performed an endoscopic bougienage, which involved a balloon dilatation and electrocoagulated incision of granular tissue under X-ray control. After that the patients were administrated by everolimus.Results. Restenosis was formed in 132,0 ± 94,2 postoperative day after primary treatment in all patients. In four cases (67% we used nitinol stent placement under X-ray control. There were no complications. In 3 cases stents were dislocated distally, so we needed to use repeated endoscopic bougienage to replace the stent. Using of everolimus has allowed to decrease the rate of restenosis, but it need future research.Conclusion. Distal bronchial stenosis after lung transplantation can be managed with endoscopic bougienage and stent placement. Adding everolimus has not signifi cantly affected the risk of frequency of restenosis.

    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.

    The authors have studied the modification of the spirometric parameters in four atopic children, during nonallergic diet, after administration of ASA (400 mg). The examination of the respiratory functionality has showed a fall of parameters starting four hours after the challenge and with an increase of respiratory resistance. This bronchospastic reaction persisted for about eighteen hours to diminish 24 h. after administration of 400 mg of ASA. The study of spirometric values has showed a remarkable fall of MMEF, sign of small airways obstruction, but also of FEV1-CV for the involvement of the higher airways. The authors attribute the reaction to the metabolites of arachidonic acid (Leukotrienes) and to their different receptor site on the bronchial mucous membrane target cells. The authors conclude showing the gravity of injury that will induce imprudent administration of ASA in hypersensitive subject.

    Diagnostic and therapeutic problems in a patient with ectopic ACTH syndrome caused by a malignant bronchial adenoma are discussed. Persistent Cushing's syndrome was present following apparent total adrenalectomy, but radioactive scanning with 131I-19-iodocholesterol showed the presence of residual adrenal tissue in the right suprarenal bed. Amelioration of the hypercortisolism occurred after removal of the bronchial adenoma. A paradoxical elevation of adrenocortical activity followed administration of dexamethasone and data are presented which suggest that periodic secretion of ACTH accounted for this phenomenon.

    To detect abnormalities of the lower respiratory tract (trachea, principal bronchi, and lobar bronchi) in brachycephalic dogs by use of endoscopy, evaluate the correlation between laryngeal collapse and bronchial abnormalities, and determine whether dogs with bronchial abnormalities have a less favorable postsurgical long-term outcome following correction of brachycephalic syndrome. Prospective case series study. 40 client-owned brachycephalic dogs with stertorous breathing and clinical signs of respiratory distress. Brachycephalic dogs anesthetized for pharyngoscopy and laryngoscopy between January 2007 and June 2008 underwent flexible bronchoscopy for systematic evaluation of the principal and lobar bronchi. For dogs that underwent surgical correction of any component of brachycephalic syndrome, owners rated surgical outcome during a follow-up telephone survey. Correlation between laryngeal collapse and bronchial abnormalities and association between bronchial abnormalities and long-term outcome were assessed. Pugs (n = 20), English Bulldogs (13), and French Bulldogs (7) were affected. A fixed bronchial collapse was recognized in 35 of 40 dogs with a total of 94 bronchial stenoses. Abnormalities were irregularly distributed between hemithoraces; 15 of 94 bronchial abnormalities were detected in the right bronchial system, and 79 of 94 were detected in the left. The left cranial bronchus was the most commonly affected structure, and Pugs were the most severely affected breed. Laryngeal collapse was significantly correlated with severe bronchial collapse; no significant correlation was found between severity of bronchial abnormalities and postsurgical outcome. Bronchial collapse was a common finding in brachycephalic dogs, and long-term postsurgical outcome was not affected by bronchial stenosis.

    Full Text Available Bronchial asthma is a prevalent chronic allergic disease of lungs at early ages. A priority  task in allergology  is to search  biological  markers  related  to uncontrolled atopic  bronchial asthma. Cytokines fulfill their distinct function in pathogenesis of atopic  bronchial asthma, participating at the initiation, development and persistence of allergic inflammation in airways, causing different  variations of clinical course of the disease (with  respect  to its acuteness, severity, frequency of exacerbations. The  present  work has studied  indices  of cellular  and  humoral links of immunity, as well as levels of some  pro and  anti-inflammatory cytokines in peripheral blood serum (IL-4, IL-10, IL-2 and TNFα, aiming to determine potential markers of uncontrolled atopic bronchial asthma in children. A group of Caucasian (European children was involved into the research: Cohort 1, moderate atopic  bronchial asthma with controlled course during the last 3 months (n = 59; Cohort 2, severe/moderate-severe atopic bronchial asthma with uncontrolled course of the disease within last 3 months (n = 51,  Cohort 3 – control, practically healthy  children without signs of atopy  (n = 33. All the  children included in the group with atopic  bronchial asthma underwent regular mono/combined basic therapy  at high/ intermediate therapeutic doses.  We performed a comparative analysis  of cell  population indices  reflecting certain cellular  immunity links,  and  determined significantly  lower  levels of CD3+   lymphocytes, as well as decrease in relative  and  absolute  contents of CD4+  and  CD8+  cells in the  cohort with  uncontrolled course of atopic  bronchial asthma, as compared with controlled-course cohort. When  evaluating concentrations  of cytokines in peripheral blood serum of the patients with controlled and uncontrolled atopic  bronchial asthma, we revealed  significantly  higher

    To evaluate peculiarities of a clinical course and changes in bronchial mucosa in bronchial asthma (BA) patients with chronic obstructive pulmonary disease (COPD) in combination with hyperoxaluria (HOU); informative value of some laboratory and device findings including oxalates assay in bronchial lavage fluid for specification of the diagnosis, role of oxalates in development of obstructive syndrome and choice of optimal therapy. Oxalates were examined in daily urine, bronchoalveolar lavage fluid and exhaled air condensate of 104 patients with BA and COPD, 77 of which had HOU and an atypical course of bronchial obstruction syndrome. Conception of airways inflammation in patients with oxalate metabolism disturbances is proposed. It is shown that insoluble oxalates participate in pathogenesis of bronchial obstruction. Oxalate metabolism disturbances are an important factor in pathogenesis of airways inflammation and development of bronchial obstruction in predisposed patients. Therefore, administration of insoluble oxalates lowering therapy may effectively prevent formation and progression of obstructive pulmonary diseases in this group of patients.

    Two patients presented with recurrent, massive haemoptysis. Arteriography, including thoracoabdominal aortograms, revealed in both cases large non-bronchial collaterals arising from the left gastric artery. In the first case the non-bronchial collateral supplied the upper left lobe and in the second case it supplied the middle right lobe. Percutaneous embolisation of bronchial and non-bronchial collateral branches has become an accepted procedure in controlling massive or recurrent haemoptysis. Accurate identification of the non-bronchial collateral arterial feeders is essential for successful embolotherapy. (orig.)

    Purpose: To establish a protocol for and to assess the value of helical CT in the imaging of the bronchial tree. Material and Methods: Noncontrast helical CT was performed in 30 patients undergoing fiberoptic bronchoscopy for different reasons. Different protocols were compared; they included overlapping 10 mm, 5 mm, or 3 mm slices and non-tilted, cephalad or caudal tilted images. Ordinary cross-sectional and multiplanar 2D reformats were applied for visualization of the bronchial branches. The effect of increasing the helical pitch was tested in one patient. Results: A total of 92.1-100% of the segmental bronchi present in the helical acquisitions were identified by the different protocols. The collimation had no significant impact on the identification of the bronchial branches, but utilization of 3-mm overlapping slices made it easier to distinguish the nearby branches and provided better longitudinal visualization of the bronchi in 2D reformats. The tilted scans illustrated the disadvantage of not covering all segmental bronchi in one breath-hold. An increase of the pitch from 1 to 1.5 did not cause noticeable blurring of the images. CT and bronchoscopic findings correlated well in the area accessible to bronchoscopy, but CT detected 5 additional pathological lesions (including 2 cancers) in the peripheral lung. Conclusion: Helical CT supplemented with bronchography-like 2D reformats provides an effective method complementary to bronchoscopy in the examination of the bronchial tree. (orig.)

  12. Advice concerning the early diagnosis of bronchial carcinoma

    International Nuclear Information System (INIS)

    1982-01-01

    Bronchial carcinoma is in the Netherlands for men the most frequent type of cancer; the incidence in women is rising. In the Netherlands nowadays, per year about 7100 persons die of this disease which therefore constitutes an important public health problem. The request of advice asks - among other things - whether in the future the periodical X-ray examination of the thorax for the detection of tuberculosis of persons over 40 years can be continued for presymptomatic cases of bronchial carcinoma. The available relevant literature does not yet give indications that periodical mass radiography has any influence on the morbidity and mortality of the disease. On the other hand, literature describing clinical experience shows that the prognosis of patients with bronchial carcinoma, detected in an early presymptomatic stage, is essentially better than in the case of patients with symptomatic disease. A critical analysis of the literature does not furnish epidemiological arguments to recommend periodical mass radiography for bronchial carcinoma. However, because lungcancer forms an extremely important public health problem and because the scarcity of randomized; controlled studies in this field, the committee advises - from a scientific point of view - to perform such a study in one or preferably two regions in the Netherlands. A number of conditions are mentioned which such a study at least should meet. (Auth.)

  13. Mechanical compression attenuates normal human bronchial epithelial wound healing

    2009-02-01

    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.

    In a previous study a higher than expected prevalence of asthma was found in Lake Munmorah, a coastal town near two power stations, compared with another coastal control town. This study aimed to compare atopy, bronchial hyperreactivity, and reported symptoms of asthma in the power station town and a second control area with greater socioeconomic similarity. A cross sectional survey was undertaken. Lake Munmorah, a coastal town near two power stations, and Dungog, a country town in the Hunter Valley, NSW, Australia. All children attending kindergarten to year 6 at all schools in the two towns were invited to participate in 1990. The response rates for the questionnaire for reported symptoms and associated demographic data were 92% in Lake Munmorah and 93% in Dungog, with 84% and 90% of children respectively being measured for lung function, atopy, and bronchial reactivity. There were 419 boys and 432 girls aged 5 to 12 years. Main outcome measures were current wheeze and bronchial hyper-reactivity, defined as a fall in forced expiratory volume in 1 second (FEV1) or peak expiratory flow (PEF) of 20% or more. Current wheeze was reported in 24.8% of the Lake Munmorah children compared with 14.6% of the Dungog children. Bronchial hyper-reactivity was similar for both groups--25.2% in Lake Munmorah and 22.3% in Dungog. The mean baseline FEV1 was lower in Lake Munmorah than in Dungog (p power station town, but bronchial hyper-reactivity and skin test defined atopy were similar in the two communities. These results are consistent with the previous study and confirm the increased presence of reported symptomatic illness in the town near power stations.

    Background Distal oesophageal spasm (DES) is a rare and under-investigated motility abnormality. Recent studies indicate effective bolus transit in varying percentages of DES patients. Aim Explore functional aspects including contraction onset velocity and contraction amplitude cut-off values for simultaneous contractions to predict complete bolus transit Methods We re-examined data from 107 impedance-manometry recordings with a diagnosis of DES. Receiver operating characteristic (ROC) analysis was conducted, regarding effects of onset velocity on bolus transit taking into account distal oesophageal amplitude (DEA) and correcting for intra-individual repeated measures. Results Mean area under the ROC curve for saline and viscous swallows were 0.84±0.05 and 0.84±0.04, respectively. Velocity criteria of >30cm/s when DEA>100mmHg and 8cm/s when DEADEA>100mmHg and >7cm/s when DEAsensitivity of 75% and specificity of 80% to identify complete bolus transit. Using these criteria, final diagnosis changed in 44.9% of patients. Abnormal bolus transit was observed in 50.9% of newly diagnosed DES patients versus 7.5% of patients classified as normal. DES patients with DEA>100mmHg suffered twice as often from chest pain than those with DEA<100mmHg. Conclusion The proposed velocity cut-offs for diagnosing distal oesophageal spasm improve the ability to identify patients with spasm and abnormal bolus transit. PMID:22475443

    Full Text Available Background: Kidney transplantation is the best treatment option for kidney failure. Major medical progress has been made in the field of renal transplantation over the last 40 years. The surgical procedure has been standardized and the complication rate is low. Overall, the outcome of renal transplantation is excellent and has improved over time. Vascular complications after renal transplantation are the most frequent type of complication following urological complications. Renal artery spasm (RAS following manipulation of renal artery is a common problem during live donor nephrectomy (LDN. The aim of this study was to determine whether or not it is necessary to wait for reverse of RAS and resumption of urinary flow before nephrectomy. Materials and Methods: In this clinical trial 16 cases of LDN who developed RAS during surgery received intra-arterial injection of 40 mg papaverine. In 8 cases surgery continued towards nephrectomy and in other 8 cases we waited for reverse of RAS. All analyses were performed using SPSS-11. Results: In both groups urinary flow started a few minutes (Mean, 12 min after declamping of transplanted kidney and normal renal consistency and color were achieved. There was no significant difference between urinary volume during 12 h after transplantation in two groups. Conclusion: The results showed that it might not be necessary to wait for reverse of RAS before LDN. Both patient (less anesthesia complications and hospital (less expenses will benefit from this time saving.

    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 examined the relationship between hemifacial spasm (HFS; a form of cranio-cervical dystonia) and chronic primary headache, including tension-type headache (TTH). We also examined whether botulinum toxin A (BoNT/A) therapy for HFS ameliorates concomitant TTH. Fifty-one HFS patients receiving BoNT/A therapy were recruited. Patients' characteristics (including age, gender, chronic headache history, exercise habits, stiff neck, cervical spondylolysis history), stress factors, worsening/new onset of headache associated with HFS, and dose of BoNT/A were examined. We diagnosed headache types according to The International Classification of Headache Disorders, 3rd edition, beta. Numerical Rating Scale (NRS) and Headache Impact Test-6 (HIT-6) scores for headache severity were compared between the 6-week baseline before BoNT/A therapy and 6-week follow-up after BoNT/A therapy. Of 51 patients with HFS, 17 (33.3%) reported worsening or new onset of headache (especially TTH) associated with HFS (Group-S), and 34 were not aware of headache (Group-N). Twelve patients (70.6%) in group-S reported improvement of headache after BoNT/A therapy. NRS (from 7 [5-9] to 0 [0-5], pheadache (odds ratio 28.53: 2.96-275.10, pheadache, especially TTH, is associated with HFS. BoNT/A therapy for HFS may also be indirectly effective for treatment of TTH. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Objective To summarize our clinical experience of microvascular decompression (MVD) for medically intractable hemifacial spasm(HFS) patients with emphasis on microsurgical manipulation and to improve cure rate and avoid surgical complications.MethodsThree hundred and thirty eight patients with HFS underwent MVD under general anesthesia. With the help of "zero retraction" technique, prosthesis can be properly inserted between offending vessel loop and affected facial nerve REZ in a "rolling ball" fashion under operative microscope.ResultsSurgical intervention achieved high relief rate of 91.4% and no major complications, with low recurrence rate of only 3.2% after averaging more than two years follow up (M=32 months).ConclusionIt is possible to approach to the facial nerve REZ with "zero retraction", which is fundamentally important to clear from cranial nerve and cerebellar injury. Skilled microsurgical technique along with correct recognition and mobilization of offending vessels are a must to assure MVD a highly efficacious and low risk treatment of choice for HFS patients.

    Objective: To design the trachea-main bronchus covered embranchment stent and study the primary treatment for thoracostomach main bronchial fistula and main bronchial stenosis. Methods: The stent was designed on the bases of the peculiar anatomic structure and the pathological changes of thoracostomach-main bronchial fistula and main bronchial stenosis. Under the fluoroscopic guidance, implantations were carried out in thoracostomach-carina fistula 1 case thoracostomach-left main bronchial fistula 1, thoracostomach-right main bronchial fistula and left main bronchial stenosis 1 case, altogether with 5 stents. Results: Stents were placed successfully, not only improving the breathing and living quality but also completing the closure of the ora of the thoracostomach-airway fistula with further vanishing of the choke after drinking and eating together with the inhalation pneumonia. The bronchus became normal in a main bronchial stenosis after the stent was taken out. Conclusions: Trachea-main bronchial covered embranchment stent could be used to close thoracostomach-airway fistula and to treat main bronchial benign/malignant stenosis. The procedure is simple and safe. (authors)

    Ten asthmatic children who gave a history of cough or wheeze after orange drinks, were tested for tartrazine sensitivity. On separate days, either oral tartrazine (1 mg) or a placebo capsule were administered double blind. Bronchial reactivity was measured before, 30 and 60 min after ingestion by means of a histamine-inhalation challenge test. There was no change in baseline lung function after tartrazine, but histamine sensitivity (PC20) increased significantly in four of the children. No response was obtained to a larger dose of tartrazine (10 mg) in four of the non-responders. Alteration in the bronchial reactivity after an oral challenge, appears to be a sensitive means of detecting tartrazine sensitivity.

    Pulmonary ventilation and perfusion scan using Xe-133 gas and Tc-99m MAA were performed in 18 patients with bronchial asthma to evaluate the regional pulmonary function. The scintigraphic findings were compared with the results of the auscultation and the conventional pulmonary functioning examination (%FVC, %FEV 1.0 ). Ventilation image showed abnormality in 12 (70.6%) out of the asymptomatic 17 patients and perfusion image showed abnormality in 7 (41.2%) out of 17 patients. These 7 patients with abnormality on perfusion image all showed abnormality on ventilation image. The grade of abnormality in scintigraphic findings was compatible with the values of %FVC and %FEV 1.0 . In conclusion Xe-133 ventilation and Tc-99m MAA perfusion scan were useful procedures to estimate the pulmonary function of patients with bronchial asthma. (author)

    2015-06-01

    Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith-Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with anteverted nose, bilateral bronchial stenosis due to lack of cartilage, bilateral obstructive renal dysplasia and NB with glomeruloid features. The infant had visceromegaly, but neither gigantism nor hemihypertrophy. Immunohistochemistry for PAX2 (Paired box gene-2) and WT-1 (Wilms Tumor 1) were strongly positive in the areas of NB. GLEPP-1 (Glomerular Epithelial Protein) did not stain the areas of NB with a glomeruloid appearance, but was positive in the renal glomeruli as expected. We found neither associated bronchial stenosis nor the histology of NB resembling giant glomeruli in any of the reported cases of NB.

    1983-01-01

    Dilated bronchi impacted with mucus or tumor are recognized on standard chest radiographs because they are surrounded by aerated pulmonary parenchyma. When imaged in different projections, these lesions produce a variety of appearances that are generally familiar. This report characterizes less familiar computed tomographic (CT) findings in eight patients with pathologic bronchial distension of congenital, neoplastic, or infectious etiologies and correlates them with chest films. In seven patients, CT readily revealed dilated bronchi and/or regional lung hypodensity. In four of these cases, CT led to the initial suspicion of dilated bronchi. CT should be used early in the evaluation of atypical pulmonary mass lesions or to confirm suspected bronchial impaction because of the high probability it will reveal diagnostic features

    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)

    scheduled 2-week periods of abstinence from LABA at 3, 6, and 12 months. Airflow, airway responsiveness, asthma symptoms, the number of symptom-free days, use of rescue medication, and scores on the Asthma Quality of Life Questionnaire (AQLQ) and the Asthma Control Questionnaire (ACQ) were also assessed....... RESULTS: The mean rate of mild exacerbations, as compared with baseline, was reduced in the bronchial-thermoplasty group but was unchanged in the control group (change in frequency per subject per week, -0.16+/-0.37 vs. 0.04+/-0.29; P=0.005). At 12 months, there were significantly greater improvements......-thermoplasty group than in the control group but were similar during the period from 6 weeks to 12 months after treatment. CONCLUSIONS: Bronchial thermoplasty in subjects with moderate or severe asthma results in an improvement in asthma control. (ClinicalTrials.gov number, NCT00214526 [ClinicalTrials.gov].)....

    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.

    Cancer of the lung in uranium miners is thought to be related to the inhalation of gaseous radon daughters which become attached to molecules of water vapour or to dust particles. Since, the depth of tissue penetration by alpha particles is short, the thickness of the epithelium that lines the bronchial tree may be a critical factor in the development of cancers at specific sites in the lung. The objectives of the present study were: 1) to measure the thickness of human bronchial epithelium; 2) to determine the distribution and depth of the nuclei of basal cells in the bronchial epithelium; and 3) to compare these parameters in groups of smokers and non-smokers. Twenty-nine surgically removed specimens of the lung were examined (26 smokers, 3 non-smokers). The specimens were fixed and prepared for examination by light and electron microscopy. Blocks of tissue were oriented so that the maximum number of bronchi were cut in cross-section; measurements included bronchi of all sizes from bronchial generations (1≥ 9.01 mm) diameter to the smallest bronchioles, generations 7 - 16 (0.26 - 2.0 mm). Comparison of measurements in smokers and non-smokers show no significant differences, so that the 29 cases are considered to represent a homogeneous group. With progressive divisions of the bronchi, the epithelium decreases in thickness. Of more importance are the figures relating to the distance from the cell surface to the underlying nucleus. Here too, with the exception of goblet cells, the measurements are significantly smaller in generations 7 - 16 than in generation 1

    The relationship between obstructive sleep apnea syndrome (OSAS) and bronchial hyperresponsiveness (BHR) is not well known. In this study, we investigated the association between BHR and disease severity in patients with OSAS. Fourty seven (37 male/10 female) OSAS patients admitted with polysomnography enrolled to the study. Histamine bronchial challenge test was performed and body mass index (BMI, kg/m2) was calculated. Presence of BHR was diagnosed as positivity of bronchial provocative test (BPT) (PD values ≤ 16 mg/mL). Patients were questioned with Epworth sleepiness scale (ESS). Histamine bronchial challenge test was positive in 21 of 47 patients. There were significant negative correlations between PD 20 value and AHI (r= -0.47, p= 0.03), BMI (r= -0.45, p= 0.03), and ESS score (r= -0.45, p= 0.03) in the patients with BHR. In addition, AHI (p= 0.03), BMI (p= 0.02), ESS scores (p= 0.03) were higher in patients with BHR (21 patients) than in patients not having BHR (26 patients). Significant negative relation was found between PD 20 value and AHI (b=-0.45, p= 0.03) and significant positive relation was found between presence of BHR and AHI (p= 0.04), BMI (p= 0.03) independently of age and sex in multiple regression analysis. BHR is common in patients with OSAS. As severity of OSAS increased, severity of BHR increased. In addition, obesity may trigger presence of BHR in patients with OSAS.

    Inhaled radon progeny are deposited in different regions of the human bronchial tree as functions of particle size and flow rate. Following deposition and mucociliary clearance, the sensitive bronchial basal and secretory cells are irradiated by two different alpha particle sources: (i) radon progeny in the sol and/or gel phase of the mucous layer, and (ii) radon progeny within the bronchial epithelium. In the case of internally deposited radionuclides, direct measurement of the energy absorbed from the ionizing radiation emitted by the decaying radionuclides is rarely, if ever, possible. Therefore, one must rely on dosimetric models to obtain estimates of the spatial and temporal patterns of energy deposition in tissues and organs of the body. When the radionuclide is uniformly distributed throughout the volume of a tissue of homogeneous composition and when the size of the tissue is large compared to the range of the particulate emissions of the radionuclide, then the dose rate within the tissue is also uniform and the calculation of absorbed dose can proceed without complication. However, if non-uniformities in the spatial and temporal distributions of the radionuclide are coupled with heterogeneous tissue composition, then the calculation of absorbed dose becomes complex and uncertain. Such is the case with the dosimetry of inhaled radon and radon progeny in the respiratory tract. There are increasing demands to obtain a definitive explanation of the role of alpha particles emitted from radon daughters in the induction of lung cancer. Various authors have attempted to evaluate the dose to the bronchial region of the respiratory tract due to the inhalation of radon daughters

    Of the bronchographic findings of 408 patients, performed in our hospital for recent 5 years, 108 cases showed definite bronchial obstruction, and 61 cases of those were selected and obstructive findings were evaluated. All that not confirmed were abandoned. For evaluation of the reliability of 9 braonchographic obstruction signs on applying to diagnose malignant or benign pulmonary diseases, each sign was identified and applied to each of the 61 confirmed cases. In addition, obstructed bronchi, distance of obstruction from the bifurcation site, and the direction of meniscus, if present, were evaluated. The results were follows: 1. The most frequent cause of bronchial obstruction was lung cancer (59.0%), and that of the benign obstruction was pulmonary tuberculosis (13.1%). 2. Amputation, asymmetric narrowing, thumbprint indentation, rat-tail narrowing and encasement signs were the most accurate signs of malignancy and were practically diagnostic ones. 3. The most frequent sign in lung cancer was sharp cutoff one, but it could be seen in lung abscess and in unresolved pneumonia, too. 4. Circumferential symmetric narrowing and regular concavity with a small central projection signs were specific ones to benignancy. 5. The most frequent obstruction sign in benign lung disease was gradual tapering sign, but it also could be seen in bronchogenic epidermoid and alveolar cell carcinoma. 6. Of all bronchial obstructions, 55.4% occurred at lobar bronchus and 77.4% of those were caused by lung cancer. 7. 77.2% of those obstruction which located within 3 times distance of the bronchial diameter at the nearest proximal bifurcation site, were lung cancer, but 75.0% of those located at over 3 times distance were benign pulmonary diseases. 8. There were no correlation of the direction of the meniscus at the obstructing end in differential diagnosis between benign and malignant pulmonary diseases

    Aerosol lung inhalation scintigraphies performed on 37 children with bronchial asthma during asymptomatic periods were evaluated. The findings of their aerosol lung inhalation scintigrams were classified into 4 patterns, as type I: homogeneous distribution without hot spot formation, type II: peripheral homogeneity with central hot spot formation, type IIID (-): inhomogeneous distribution with hot spot formation, but without defect, and type IIID (+): with defect. These aerosol patterns were compared with those of previously reported adult cases and with the severity of bronchial asthma. Normal pattern of type I was found in 5 cases (12%) of our infantile asthmatics in contrast to previously reported adult cases, in which none of normal pattern was found. There were differences between type II and type III in both distribution and disappearance time of hot spot, which indicated that the two types differed from each other in radioaerosol deposition mechanism. There was no significant correlation between type I and type II in the severity of asthma and the frequency of asthmatic attack. Type II may be clinically considered to be the same type as type I. There is the statistically significant difference between type I, II and type III in the frequency of asthmatic attack, but not in the severity of asthma, although most of serious cases showed type III. Aerosol lung inhalation scintigraphy is a useful examination for children with bronchial asthma in which lung function tests may be difficult to perform. (author)

    Painful tonic spasm (PTS) is a common symptom in patients with neuromyelitis optica spectrum disorders (NMOSD). This study aimed to obtain further insights into the prevalence, characteristics, and treatment of PTS in patients with NMOSD, and to systematically investigate and compare the clinical features and prognosis of NMOSD with and without PTS. We reviewed the medical records and prospectively interviewed patients with NMOSD who attended the West China Hospital of Sichuan University in Chengdu, China between September 2014 and December 2016. In total, 52 of the 230 patients with NMOSD experienced PTS (22.61%). Patients with NMOSD and PTS were characterized by a higher age at onset (P = 0.017), higher annual relapse rate (ARR) (P = 0.003), higher ARR of myelitis (P = 0.011), and a tendency to experience pruritus (P = 0.025). Sodium channel blocking antiepileptic drugs (carbamazepine or oxcarbazepine) had higher efficacy than gabapentin in the treatment of PTS (P = 0.001). Although the progression index was higher in patients with PTS, this difference did not reach statistical significance (P = 0.05). Our study suggested that immunosuppressors for the prevention of relapse should be administered without delay in patients with NMOSD and PTS. Owing to the side effects of carbamazepine, we recommend oxcarbazepine as the first-line of treatment for PTS in patients with NMOSD. Whether PTS is a marker of disease severity in NMOSD remains to be determined, requiring a long-term prospective observational study. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available BACKGROUND AND AIMS: Non-motor symptoms (NMS are important manifestations of Parkinson's disease (PD that reduce patients' health-related quality of life. Some NMS may also be caused by age-related changes, or manifested as a psychological reaction to a chronic neurological condition. This case-control study compared the NMS burden among PD patients, healthy controls and hemifacial spasm (HFS patients. In addition, we determined the NMS that discriminated between PD and non-PD subjects. METHODS: 425 subjects were recruited from a tertiary hospital in Singapore (200 PD patients, 150 healthy controls and 75 HFS patients. NMS burden in subjects was measured using the Non-Motor Symptoms Scale (NMSS. RESULTS: NMSS total score was significantly higher in PD patients (37.9±2.6 compared to healthy controls (11.2±0.9 (p<0.0001 and HFS patients (18.0±2.1 (p<0.0001. In addition, NMSS total score was significantly higher in HFS patients compared to healthy controls (p = 0.003. PD patients experienced a higher NMS burden than healthy controls in all domains, and a higher NMS burden than HFS patients in all but attention/memory and urinary domains. NMS burden for HFS and healthy controls differed only in the sleep/fatigue and urinary domains. Using stepwise logistic regression, problems of 'constipation', 'restless legs', 'dribbling saliva', 'altered interest in sex' and 'change in taste or smell' were found to have significant discriminative power in differentiating between PD patients and healthy controls and between PD patients and HFS patients. CONCLUSION: PD patients experienced a greater overall NMS burden compared to both healthy controls and HFS patients. HFS patients demonstrated a higher NMS burden than controls, and some NMS may be common to chronic neurological conditions while others are more specific to PD. Differentiating patients using NMS domains may help refine the clinical management of NMS in PD patients.

    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)

    An analysis of bronchial mucus proteins was carried out by crossed immunoelectrophoresis. Before electrophoretic migration, sputum was treated with Ecteola-cellulose, which retains acid mucins. The proteins were then extracted by a phosphate/saline buffer pH 7.5. Crossed immunoelectrophoresis of the "bronchial extracts" was carried out with an anti-human serum: fifteen proteins were detected. Among them, IgA and protease inhibitiors play an important role in bronchial pathology. Bronchial extracts were also studied with immune serums against milk proteins, whole saliva and proteins of bronchial mucus. Bronchotransferrin, amylase and two esterases were characterized. Four other proteins were also detected with immune serums against bronchial mucus-proteins: their biological role is still unknown.

    Objective: To assess the diagnostic value of multi-slice spiral CT virtual bronchoscopy (CTVB) in tracheal and bronchial disease. Methods: Forty-two patients including central lung cancer (n=35), endobronchial tuberculosis (n=3), intrabronchial benign tumor (n=3), and intrabronchial foreign body (n=1) were examined by using multi-slice spiral CT examinations. All the final diagnosis were proved by pathology except 1 patient with endoluminal foreign body was proved by clinic. All patients were scanned on GE Lightspeed 99 scanner, using 10 mm collimation, pitch of 1.35, and reconstructed at 1 mm intervals and 1.25 mm thickness. The chest images of transverse CT and virtual bronchoscopy were viewed by two separate radiologists who were familiar with the tracheal and bronchial anatomy. Results: Among the 42 patients, the tumor of trachea and bronchial lumen appeared as masses in 22 of 35 patients with central lung cancer and bronchial stenosis was found in 13 of 35 patients with central lung cancer, and bronchial wall thickening was revealed on transverse CT in all 35 cases. 3 patients of endobronchial tuberculosis showed bronchial lumen narrowing on CTVB, the bronchial wall thickening was revealed on transverse CT, and the length of the wall thickening was long. 3 patients with intrabronchial benign tumor showed nodules in trachea and bronchial lumen on CTVB, and without wall thickening on transverse CT. CTVB could detect the occlusion of bronchial lumen in 1 patient with intrabronchial foreign body and CTVB was able to visualize the areas beyond stenosis, and the bronchial wall was without thickening on transverse CT. Conclusion: Multi- slice spiral CTVB could reflect the morphology of tracheal and bronchial disease. Combined with transverse CT, it could provide diagnostic reference value for bronchial disease.

    Objective: To evaluate the ability of CT angiography in identifying and demonstrating the origins and courses of bronchial arteries by using the three-dimensional reformation technique. Methods Four hundred and forty-three eases were examined with thin-section enhanced MSCT. Three-dimensional images of bronchial arteries were processed at the workstation. Spatial anatomical characters of the bronchial arteries using volume rendering(VR), muhiplanar reconstruction (MPR), and maxium intensity projection (MIP) were observed. Results: At least one bronchial artery was clearly displayed in VR in 359 eases. The right bronchial arteries mainly appeared to originate from the right intercostal artery (213/436, 48.85% ) and descending aorta (207/436, 47.48%), while the left bronchial arteries mainly from the descending aorta (363/371, 97.84%). The right bronchial arteries of the descending aorta were mainly arised from fight wall (95/207, 45.89%), and then the anterior wall (88/207, 42.51%), while the left bronchial arteries of the descending aorta mainly arised from anterior wall of the aorta (272/363, 74.93%). The common trunk originated from the descending aorta mainly positioned in the anterior wall (57/77, 74.03%). 49.31% (215/436) of the fight bronchial arteries were coursing across the posterior edge of the right main bronchi, 35.55% (155/436) coursing the inferior edge, while 60.11% (223/371) of left bronchial arteries coursing forward across the superior edger of the left main bronchi, the others coursing the inferior or the posterior edge. There were eleven bronchial artery distribution patterns, with the right and left ones predominating (192/359, 53.48%), and then two right and one left (63/359, 17.55%). Conclusion: The bronchial artery anatomy was complicated, and CT angiography could clearly visualize the features. (authors)

    In this study, we aimed to reveal the normal anatomy and variations of the bronchial arterial system and to determine the sex distribution of these variations by retrospectively reviewing the images of patients who underwent thoracal multidetector computed tomographic angiography for various reasons. Multidetector computed tomographic images of a total of 208 patients (151 men; mean age, 59 years) were retrospectively reviewed to assess the normal anatomy and variations of the bronchial arterial system. A total of 531 bronchial arteries (median, 3; minimum, 1; maximum, 5; mean, 2.5) were detected. The number (mean diameter) of the right bronchial arteries were higher than the left bronchial arteries (290 [1.43 mm] and 241 [1.26 mm], respectively; P arteries were higher with men than with women (2.58 [1.45 mm] and 2.47 [1.32 mm], respectively; P artery, and, secondarily (13.46%), the combination of 2 right (1 intercostal-bronchial trunk and 1 bronchial artery) and 1 left bronchial arteries. Seventy-eight ectopic bronchial arteries were detected in 59 cases (28.3%). They most commonly originated from the aortic arch (37.2%), the descending aorta below the level of T6 (35.9%), or the aortic branches (16.7%). The number of right ectopic bronchial arteries was significantly higher than the left ectopic bronchial arteries (50 [64%] vs 28 [36%]; P arteries was statistically higher with men versus women (45 [29.8%] vs 14 [24.6%]; P arteries can vary substantially among individuals. Multidetector computed tomographic angiography enables a detailed road map of the bronchial arterial system to interventional radiologists and thoracic surgeons.

    To evaluate the immediate and long-term results of arterial embolisation in the management of haemoptysis and to identify factors influencing outcome. A retrospective analysis was carried out of the medical records and angiograms of 50 patients who underwent transarterial embolisation for haemoptysis. The most frequent causes of haemoptysis included bronchiectasis (16%), active tuberculosis (12%) and aspergilloma (12%). A total of 126 bronchial and non-bronchial systemic arteries were embolised in 62 procedures. Immediate cessation of haemoptysis was achieved in 43 patients (86%). Haemoptysis was controlled in 36 patients (72%), recurred in 14 (28%) and 11 (22%) required repeat embolisation. The worst outcomes were observed in patients with aspergilloma: all six suffered recurrent bleeding and three (50%) died from massive haemoptysis. Aspergilloma was also associated with an increased risk of haemoptysis recurrence (p<0.05). A good clinical outcome was achieved in those with active tuberculosis and malignancy. Complication rates were low and included transient chest pain, false aneurysm and one case of lower limb weakness. Bronchial artery embolisation (BAE) is an effective and safe procedure for haemoptysis control in most cases. However, high recurrence and mortality rates are associated with aspergilloma. Early intervention with repeat embolisation is recommended in these patients and elective surgery should be considered. (orig.)

    Clinical experience has shown that allergic and non-allergic respiratory, metabolic, mental, and cardiovascular disorders sometimes coexist with bronchial asthma. However, no study has been carried out that calculates the chance of manifestation of these disorders with bronchial asthma in Saarland and Rhineland-Palatinate, Germany. Using ICD10 diagnoses from health care institutions, the present study systematically analyzed the co-prevalence and odds ratios of comorbidities in the asthma population in Germany. The odds ratios were adjusted for age and sex for all comorbidities for patients with asthma vs. without asthma. Bronchial asthma was strongly associated with allergic and with a lesser extent to non-allergic comorbidities: OR 7.02 (95%CI:6.83-7.22) for allergic rhinitis; OR 4.98 (95%CI:4.67-5.32) allergic conjunctivitis; OR 2.41 (95%CI:2.33-2.52) atopic dermatitis; OR 2.47 (95%CI:2.16-2.82) food allergy, and OR 1.69 (95%CI:1.61-1.78) drug allergy. Interestingly, increased ORs were found for respiratory diseases: 2.06 (95%CI:1.64-2.58) vocal dysfunction; 1.83 (95%CI:1.74-1.92) pneumonia; 1.78 (95%CI:1.73-1.84) sinusitis; 1.71 (95%CI:1.65-1.78) rhinopharyngitis; 2.55 (95%CI:2.03-3.19) obstructive sleep apnea; 1.42 (95%CI:1.25-1.61) pulmonary embolism, and 3.75 (95%CI:1.64-8.53) bronchopulmonary aspergillosis. Asthmatics also suffer from psychiatric, metabolic, cardiac or other comorbidities. Myocardial infarction (OR 0.86, 95%CI:0.79-0.94) did not coexist with asthma. Based on the calculated chances of manifestation for these comorbidities, especially allergic and respiratory, to a lesser extent also metabolic, cardiovascular, and mental disorders should be taken into consideration in the diagnostic and treatment strategy of bronchial asthma. PREVALENCE OF CO-EXISTING DISEASES IN GERMANY: Patients in Germany with bronchial asthma are highly likely to suffer from co-existing diseases and their treatments should reflect this.

    Background The importance of the role of bronchial arteries is notable in modern days thoracic surgery. The significance of their anastomoses with adjusted structures has not yet been sufficiently rated, especially in cases of haemoptysis, heart-lung transplantations and treatment of aneurysms of the thoracic aorta. The need of a thorough study is more relevant than ever and appropriate laboratory animals are required. Methods We review the literature in order to highlight the ideal experimental animal for the implementation of pilot programs relative to the bronchial circulation. A comparative analysis of the anatomy of the bronchial arterial system in humans along with these of pigs, dogs, rats, and birds, as being the most commonly used laboratory animals, is presented in details. Results The pig has the advantage that the broncho-oesophageal artery usually originates from the aorta as a single vessel, which makes the recognition and dissection of the artery easy to perform. In dogs, there is significant anatomical variation of the origin of the bronchial arteries. In rats, bronchial artery coming from the aorta is a rare event while in birds the pattern of the bronchial artery tree is clearly different from the human analog. Conclusions The pig is anatomically and physiologically suited for experimental studies on the bronchial circulation. The suitable bronchial anatomy and physiology along with the undeniable usefulness of the pig in experimental research and the low maintenance cost make the pig the ideal model for experiments in bronchial circulation.

    This study was performed to determine the sensitivity of thallium imaging vs ECG monitoring for detecting coronary artery spasm noninvasively following intravenous ergonovine administration as compared to simultaneous coronary angiography. Thirty-two patients with insignificant coronary artery disease and chest pain underwent 12-lead ECG monitoring, thallium imaging, and coronary arteriography following the administration of 0.05, 0.1, 0.2, and 0.3 mg of ergonovine given 5 minutes apart or until chest pain occurred. One minute following the last dose of ergonovine, 2.5 mCi of thallium-201 was injected intravenously, and a final ECG was recorded and repeat coronary arteriography performed. Within 10 minutes following the injection of thallium, imaging was performed in the 40-degree and 70-degree left anterior oblique and anterior projections. The ECG, thallium study, and coronary arteriogram were read blindly and results were compared. The ECG, angiogram, and thallium study were read as positive if the following occurred, respectively: greater than or equal to 1 mm ST segment elevation, depression, or T wave reversal; greater than 50% vessel narrowing,; and reversible perfusion defect. Five patients were excluded from analysis because of either catheter-induced spasm, suboptimal thallium studies, or protocol violations. Of the 27 patients included for analysis, six had chest pain, five had a positive angiogram, five had a positive thallium study, and one had a positive ECG. The sensitivity of thallium vs ECG monitoring was 80% vs 25%, and the accuracy was 92% vs 80%. We conclude that thallium imaging greatly increases the noninvasive detection of ergonovine-induced coronary spasm as compared with the ECG with no loss of accuracy

    Chronic prostatitis/chronic pelvic pain syndrome is a common condition that often requires multimodal therapy. Patients with chronic pelvic pain syndrome have a high incidence of pelvic floor spasm, which can be treated with pelvic floor physical therapy. However, this is a specialized skill. We compared outcomes of pelvic floor physical therapy as part of multimodal therapy in patients with chronic pelvic pain syndrome between those treated at our institution and elsewhere. We identified patients from our chronic pelvic pain syndrome registry with pelvic floor spasm who were seen between 2010 and 2014 for more than 1 visit. Patient phenotype was assessed with the UPOINT system and symptom severity was determined by the National Institutes of Health CPSI. A 6-point decrease in CPSI was used to define patient improvement. A total of 82 patients fit the study criteria. Mean age was 41.6 years (range 19 to 75) and median symptom duration was 24 months (range 3 to 240). Mean CPSI was 26.8 (range 10 to 41), the median number of positive UPOINT domains was 3 (range 1 to 6) and 27 patients (32.9%) were treated locally. At followup 9 patients had refused pelvic floor physical therapy, and 24 and 48 had undergone pelvic floor physical therapy elsewhere and at CCF, respectively. The mean change in CPSI was 1.11 ± 4.1 in patients who refused, -3.46 ± 6.7 in those treated elsewhere and -11.3 ± 7.0 in those treated at CCF (p physical therapy at CCF (OR 4.23, p = 0.002) and symptom duration (OR 0.52, p = 0.03) predicted improvement. Pelvic floor physical therapy can be effective for chronic pelvic pain syndrome in patients with pelvic floor spasm. However, the outcome depends on specialty training and experience of therapists.

    The aims of this systematic review and meta-analysis were to assess (i) estimates of good neurodevelopmental outcome in infantile spasms (IS), (ii) if neurodevelopmental outcome has changed since the publication of the first guideline on medical treatment of IS in 2004 and (iii) effect of lead time to treatment (LTTT). The Medline, Embase, Cochrane, PsycINFO, Web of Science and Scopus databases, and reference lists of retrieved articles were searched. Studies inclusion criteria were: (i) >5 patients with IS, (ii) mean/median follow-up of >6 months, (iii) neurodevelopmental outcome, and (iv) randomized and observational studies. The data extracted included proportion of good neurodevelopmental outcome, year of publication, cryptogenic or symptomatic IS and LTTT. Of the 1436 citations screened, 55 articles were included in final analysis, with a total of 2967 patients. The pooled estimate for good neurodevelopmental outcome was 0.236 (95% CI: 0.193-0.286). There was no difference between the proportions of good neurodevelopmental outcome for the 21 studies published after 2004 [0.264 (95% CI: 0.197-0.344)] compared to the 34 studies published before 2004 [0.220 (95% CI: 0.168-0.283)] (Q value=0.862, p=0.353). The pooled estimate of good neurodevelopmental outcome for cryptogenic IS [0.543 (95% CI: 0.458-0.625)] was higher than symptomatic IS [0.125 (95% CI: 0.09-0.171)] (Q value=69.724, p4weeks for good neurodevelopmental outcome of 8 studies was 1.519 (95% CI: 1.064-2.169). Neurodevelopmental outcome was overall poor in patients with IS and has not changed since the publication of first guideline on IS. Although cryptogenic IS has better prognosis than symptomatic IS, the outcome for cryptogenic IS remained poor. There was heterogeneity in neurodevelopmental outcome ascertainment methods, highlighting the need for a more standardized and comprehensive assessment of cognitive, behavioural, emotional and functional outcomes.

    To address the feasibility and predictive value of multimodal image-based virtual reality in detecting and assessing features of neurovascular confliction (NVC), particularly regarding the detection of offending vessels, degree of compression exerted on the nerve root, in patients who underwent microvascular decompression for nonlesional trigeminal neuralgia and hemifacial spasm (HFS). This prospective study includes 42 consecutive patients who underwent microvascular decompression for classic primary trigeminal neuralgia or HFS. All patients underwent preoperative 1.5-T magnetic resonance imaging (MRI) with T2-weighted three-dimensional (3D) sampling perfection with application-optimized contrasts by using different flip angle evolutions, 3D time-of-flight magnetic resonance angiography, and 3D T1-weighted gadolinium-enhanced sequences in combination, whereas 2 patients underwent extra experimental preoperative 7.0-T MRI scans with the same imaging protocol. Multimodal MRIs were then coregistered with open-source software 3D Slicer, followed by 3D image reconstruction to generate virtual reality (VR) images for detection of possible NVC in the cerebellopontine angle. Evaluations were performed by 2 reviewers and compared with the intraoperative findings. For detection of NVC, multimodal image-based VR sensitivity was 97.6% (40/41) and specificity was 100% (1/1). Compared with the intraoperative findings, the κ coefficients for predicting the offending vessel and the degree of compression were >0.75 (P < 0.001). The 7.0-T scans have a clearer view of vessels in the cerebellopontine angle, which may have significant impact on detection of small-caliber offending vessels with relatively slow flow speed in cases of HFS. Multimodal image-based VR using 3D sampling perfection with application-optimized contrasts by using different flip angle evolutions in combination with 3D time-of-flight magnetic resonance angiography sequences proved to be reliable in detecting NVC

    The purpose of this study was to determine non-invasively the frequency of ectopic bronchial arteries (BA) (i.e., bronchial arteries originating at a level of the descending aorta other than T5-T6 or from any aortic collateral vessel) on multidetector-row CT angiograms (CTA) obtained in patients with hemoptysis. Over a 5-year period (2000-2005), 251 consecutive patients with hemoptysis underwent multidetector-row CT angiography of the thorax. From this population, 37 patients were excluded because of a suboptimal CTA examination (n = 19), the presence of extensive mediastinal disease (n = 15) or severe chest deformation (n = 3) precluding any precise analysis of the bronchial arteries at CTA. Our final study group included 214 patients who underwent a thin-collimated CT angiogram (contrast agent: 300 to 350 mg/ml) on a 4- (n = 56), 16- (n = 119) and 64- (n = 39) detector-row scanner. The site of origin and distribution of bronchial arteries were analyzed on transverse CT scans, maximum intensity projections and volume-rendered images. The site of the ostium of a bronchial artery was coded as orthotopic when the artery originated from the descending aorta between the levels of the fifth and sixth thoracic vertebrae; all other bronchial arteries were considered ectopic. From the studied population, 137 (64%) patients had only orthotopic bronchial arteries, whereas 77 patients (36%) had at least one bronchial artery of ectopic origin. A total of 147 ectopic arteries were depicted, originating as common bronchial trunks (n = 23; 19%) or isolated right or left bronchial arteries (n = 101; 81%). The most frequent sites of origin of the 124 ostiums were the concavity of the aortic arch (92/124; 74%), the subclavian artery (13/124; 10.5%) and the descending aorta (10/124; 8.5%). The isolated ectopic bronchial arteries supplied the ipsilateral lung in all but three cases. Bronchial artery embolization was indicated in 26 patients. On the basis of CTA information, (1

    The bronchial diameter measured on computed tomography (CT) can be used to guide double-lumen tube (DLT) sizes objectively. The bronchus is known to be measured most accurately in the so-called bronchial CT window. The authors investigated whether using the bronchial window results in the selection of more appropriately sized DLTs than using the other windows. CT image analysis and prospective randomized study. Tertiary hospital. Adults receiving left-sided DLTs. The authors simulated selection of DLT sizes based on the left bronchial diameters measured in the lung (width 1,500 Hounsfield unit [HU] and level -700 HU), bronchial (1,000 HU and -450 HU), and mediastinal (400 HU and 25 HU) CT windows. Furthermore, patients were randomly assigned to undergo imaging with either the bronchial or mediastinal window to guide DLT sizes. Using the underwater seal technique, the authors assessed whether the DLT was appropriately sized, undersized, or oversized for the patient. On 130 CT images, the bronchial diameter (9.9 ± 1.2 mm v 10.5 ± 1.3 mm v 11.7 ± 1.3 mm) and the selected DLT size were different in the lung, bronchial, and mediastinal windows, respectively (p study, oversized tubes were chosen less frequently in the bronchial window than in the mediastinal window (6/110 v 23/111; risk ratio 0.38; 95% CI 0.19-0.79; p = 0.003). No tubes were undersized after measurements in these two windows. The bronchial measurement in the bronchial window guided more appropriately sized DLTs compared with the lung or mediastinal windows.

    Whether the main points of treatment for bronchial obstructive syndrome (BOS) in chronic obstructive lung disease (COLD) can be adapted for patients with pulmonary tuberculosis (PT) was studied. For this purpose, 435 patients with PT with signs of BOS (forced expiratory volume at 1 second (FEV1) 70% of the normal values; 2) 229 patients with FEV1 69-50%; 3) 102 patients with FEV1 bronchial obstructive syndrome in patients with pulmonary tuberculosis was highly effective, promotes the amelioration of the degree of respiratory symptoms in patients with IPT by 2 to 8 times, in those with FCPT by more than 2-3 times, and in those with PS by 1.45-10 times. The differences in the efficiency of bronchodilator therapy depend on the baseline level of bronchial obstruction. In patients with pulmonary tuberculosis concurrent with BO, the use of current inhalation bronchodilator therapy results in a substantial increase in FEV1, which differentiates BOS in PT from COLD. The use of the proposed therapy in the multimodality treatment of patients with pulmonary tuberculosis showed no statistically significant differences in the changes in the degree of X-ray symptoms while this therapy permits acceleration of abacillation in patients with IPT by 16.8% and in those with FCPT by 14.8%. Effective bronchodilator therapy considerably enhances life quality in patients. Thus, early systematic and long-term performance of the bronchodilator therapy, based on the principles of bronchodilator therapy for COLD, in patients with PT concurrent with BOS may substantially enhance the efficiency of treatment in this category of patients.

  18. Proinflammatory effects of cookstove emissions on human bronchial epithelial cells.

    Approximately half of the world's population uses biomass fuel for indoor cooking and heating. This form of combustion typically occurs in open fires or primitive stoves. Human exposure to emissions from indoor biomass combustion is a global health concern, causing an estimated 1.5 million premature deaths each year. Many 'improved' stoves have been developed to address this concern; however, studies that examine exposure-response with cleaner-burning, more efficient stoves are few. The objective of this research was to evaluate the effects of traditional and cleaner-burning stove emissions on an established model of the bronchial epithelium. We exposed well-differentiated, normal human bronchial epithelial cells to emissions from a single biomass combustion event using either a traditional three-stone fire or one of two energy-efficient stoves. Air-liquid interface cultures were exposed using a novel, aerosol-to-cell deposition system. Cellular expression of a panel of three pro-inflammatory markers was evaluated at 1 and 24 h following exposure. Cells exposed to emissions from the cleaner-burning stoves generated significantly fewer amounts of pro-inflammatory markers than cells exposed to emissions from a traditional three-stone fire. Particulate matter emissions from each cookstove were substantially different, with the three-stone fire producing the largest concentrations of particles (by both number and mass). This study supports emerging evidence that more efficient cookstoves have the potential to reduce respiratory inflammation in settings where solid fuel combustion is used to meet basic domestic needs. Emissions from more efficient, cleaner-burning cookstoves produced less inflammation in well-differentiated bronchial lung cells. The results support evidence that more efficient cookstoves can reduce the health burden associated with exposure to indoor pollution from the combustion of biomass. © 2012 John Wiley & Sons A/S.

Taking 18 hospitalized cerebral stroke patients for example, through scanning, molding and printing, to make and wear 3D printing fingerboard for them, and then observe the compliance, main complaint, muscular tension of affected hand and changes on range of motion after they wear the fingerboard for 3 weeks and 3 months. Have acquired completed data from 13 patients. The time of them wearing the fingerboard every day varied from 1 to 8 h, and most of them reflected that they felt comfortable and there was no feeling of worsened pain or finger skin allergy. In addition, the patients' grip strength, hand function and range of motion improved by varying degrees while their muscular tensions declined by varying degrees. The tension and bending resistance of the fingerboard all met the patients' treatment requirements. With the advantages of being accurate and customized, 3D printing fingerboard can benefit patients fixing and orthopedic treatment, and even prevent and treat cerebral stroke patient's finger spasm.

    Instituting drug holidays for chronic opioid using patients is becoming commonplace for pain practitioners initiating procedures such as intrathecal pump or spinal cord stimulator trials. As such, pain practitioners need to be adept in their management of acute opioid withdrawal. Successfully weaning an opioid dependent patient off of chronic opioids requires a thorough knowledge of the available adjuvants to assist in this process. However, that selection can become exhausted by adjuvant side effects or by ineffective attenuation of opioid withdrawal symptoms. In that case, novel drugs, or novel application of currently available medications must be sought after to assist in the drug holiday. We present a case in which refractory muscle spasms secondary to opioid withdrawal were successfully treated with an over-the-counter supplement that is not typically used for the attenuation of opioid withdrawal symptoms. In a patient intolerant to the side effects of clonidine, we were able to successfully wean chronic opiates by treating refractory muscle spasms with the serotonin precursor, 5-hydroxytryptophan (5-HTP). We hypothesize that our success with this medication gives further credence to the role of serotonin in opioid withdrawal somatic symptomatology, and supports the need for future research to clarify the role of serotonin precursors or serotonin modulating drugs as potential alternatives in those unable to follow standard treatment protocols.

    This clinical trial of fenspiride (injectable and sustained-release 80 mg tablet) was carried out on patients selected because their bronchopathy was of a hypersecretory type. Interesting results were observed in 20 out of 37 cases, but they were often delayed. This group of patients included a high proportion of patients with major hypersecretion; the efficacy of fenspiride is often evident, (in 8 out of 11 cases) but it is unpredictable individually. It can be concluded from this trial that a long term treatment with fenspiride, well tolerated, can usefully be tried in patients with predominant signs of bronchial hyperexudation.

    Tracheobronchial stenosis is common in the thoracic surgery service, and iatrogenic injury of the airway after manipulation is not infrequent. When a digital thoracic drainage system came onto the market, many advantages were evident. A 24-year-old woman with critical right main bronchial stenosis underwent airway dilation that was complicated by a tear with a massive air leak, resulting in a total right pneumothorax. We employed a pleural drain connected to a digital thoracic drainage system. The drain was removed 2 days after successful resolution of the air leak. © The Author(s) 2015.

    Full Text Available Dysphagia in an elderly patient necessitates urgent clinical evaluation to exclude the possibility of an underlying esophageal malignancy. Atherosclerotic aortic aneurysms are common in old age, but dysphagia aortica resulting from compression of the esophagus by an aortic aneurysm is a rare cause for dysphagia. Development of a malignant esophago-airway fistula can occur from a variety of tumors, the most common of which is esophageal cancer. A case of longstanding dysphagia resulting from dysphagia aortica later developing an esophageal malignancy complicated by esophago-bronchial fistula is outlined in this unique case report.

    To evaluate alveolar epithelial permeability (k ep ) in children with bronchial asthma, 99m Tc-DTPA (diethylene triamine penta acetate) aerosol lung inhalation scintigraphies were performed. There was no correlation between the k ep value and the severity of asthma. On the other hand, out of 10 cases which had no aerosol deposition defect in the lung field, 4 showed high k ep values on the whole lung field and 7 had high k ep value areas, particularly apparent in the upper lung field. These results suggest that even when the central airway lesions are mild, severe damage exists in the alveolar region of the peripheral airway. (author)

    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 mobilisation 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, characterised by painless and aseptic technique and outstanding clinical results. 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. Patients with bronchial asthma presented with significant improvement (p lower frequency and intensity of attacks. The mechanism of laser stimulation activity in treatment of bronchial asthma is explained in detail, correlating our results to those obtained by other authors. A ten-day course of low-power laser stimulation of acupuncture points in patients with bronchial asthma improves both the lung function and gas exchange parameters.

    Sphincter of Oddi spasm from opioids has been documented, presenting as severe epigastric pain and potentially overlooked in a differential diagnosis. We present a case of sphincter of Oddi spasm from periarticular morphine in a patient under spinal anesthesia, causing severe distress and treated effectively with glucagon. It is important for anesthesiologists using opioids to consider it as a cause of perioperative pain and be familiar with treatment as it may be refractory by conventional use of opioids for pain relief. It is also important to consider the systemic effects of periarticular absorption, as evident by our case.

    The uptake of percutaneous coronary procedures via the radial artery has increased internationally due to the decreased risk of complications and increased patient satisfaction. The increased susceptibility of the radial artery to spasm however presents a potential risk for procedural failure. Although most experts agree on the need for prophylactic medications to reduce radial artery spasm, currently there is inconsistency in literature regarding the most effective vasodilatory medication or combination of medications. The objective of this study is to identify the effectiveness of vasodilatory medications on radial artery spasm in patients undergoing transradial coronary artery procedures. This review considered studies that included participants aged 18 years and over undergoing non-emergent transradial percutaneous coronary artery procedures. This review considered studies that used vasodilating intravenous and intra-arterial medications or combinations of medications prior to commencing and during transradial coronary approaches to reduce radial artery spasm. The outcomes of interest were the incidence of radial artery spasm during percutaneous coronary procedure using objective and/or subjective measures and its effect on the successful completion of the procedure. Randomized controlled trials published in the English language between 1989 to date were considered for inclusion. The search strategy aimed to find both published and unpublished studies. A three-step search strategy was utilized in this review. An initial search of MEDLINE, CINAHL and Scopus was undertaken, followed by a search for unpublished studies. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments. Any disagreements that arose between the reviewers were resolved through discussion. Quantitative data was extracted from papers included in the review using the

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.

    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.

    To assess bronchial morphology and abnormality, 14 children with congenital heart diseases including 2 postoperative patients (age, 2 m.-4 yr) were studied by digital video subtraction fluorography (DVSF) using digital subtraction and image processing system (Philips, DVI-2). This newly developed technique clearly defined bronchial anatomy in all 14 patients. Bronchial situs could be determined in all 8 patients with complex heart anomalies. Out of 8 patients with respiratory distress in this study, obvious bronchial stenosis or obstruction was found by DVSF in 5 patients. Thus, DVSF image defined anatomies of main and lobar bronchi more clearly than previous noninvasive methods. Moreover, DVSF is noninvasive and easily performed even for small infants and critically ill patients. In conclusion, DVSF may be a useful technique to assess bronchial morphology and abnormality in patients with congenital heart diseases. (author)

    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.

    An interactive virtual environment for simulation of bronchoscopy is developed. Medical doctor can safely plan their surgical bronchoscopy using the virtual environment without any invasive diagnosis which may risk the patient's health. The 3D pen input device of the system allows the doctor to navigate and visualize the bronchial tree of the patient naturally and interactively. To navigate the patient's bronchial tree, a vessel tracking process is required. While manual tracking is tedious and labor-intensive, fully automatic tracking may not be reliable. We propose a semi-automatic tracking technique called Intelligent Path Tracker which provides automation and enough user control during the vessel tracking. To support an interactive frame rate, we also introduce a new volume rendering acceleration technique, named as IsoRegion Leaping. The volume rendering is further accelerated by distributed rendering on a TCP/IP-based network of low-cost PCs. With these approaches, a 256 x 256 x 256 volume data of human lung, can be navigated and visualized at a frame rate of over 10 Hz in our virtual bronchoscopy system.

    Objective:To evaluate the action of 2% lidocaine on the culture results of bronchial fluid in patients suspected of having lower respiratory tract infections. Study Design:Cross-sectional analytical study. Place and Duration of Study:Shahid Sadoughi Hospital, Yazd, Iran, from November 2014 to November 2015. Methodology:Patients suspected of lower respiratory tract infections referred to bronchoscopy unit of the Hospital were included. Those with incomplete questionnaire and bronchoscopy contraindication were excluded. Bronchial fluid was aspirated before and after local application of 2% lidocaine and cultured, according to the suspected clinical diagnosis. Finally, statistical analysis was performed using SPSS software, version 17.0. For statistical comparisons, McNemar's test was used. Level of significance was kept at p <0.05. Results:The mean age of the study population was 51.83 +-15.93 with a range of 25 - 80 years. Out of 130 patients, 60 patients had positive culture results. Nineteen (31.7%) cases had positive culture for tuberculosis and 41 (63.3%) cases had positive results for other bacteria before intervention that did not change after using 2% lidocaine (p=1). In 70 (53.84%) cases, results were negative before and after use of 2% lidocaine. Conclusion:No significant difference was found between culture results before and after the use of lidocaine. Therefore, lidocaine can be used during bronchoscopy to increase patient tolerance. (author)

    Bronchial thermoplasty (BT) is an emerging treatment modality for patients with difficult to treat asthma. It has been shown to be beneficial for symptom control and improves quality of life and reduces frequency of hospitalization. Safety data from the two major trials of BT indicate that patients who undergo these procedures are most likely to experience adverse respiratory events in the first six weeks post treatment. Lung abscess has never been reported as a direct complication of BT. In this case; we report a lung abscess as an immediate complication of BT, which we believe may be the first case. We describe a forty three year old Caucasian female presented three days post-bronchial thermoplasty with left sided chest pain radiating to the back associated with shortness of breath, wheeze and dry cough. She had also started to feel hot and cold and generally unwell. It remains unclear why this patient developed a lung abscess so acutely post BT treatment. It is important that safety data continues to be collated and published as the procedure becomes more widely available with further long term follow-up in particular.

    RI-angiography with sup(99m)TcO 4 - was carried out using a scintillation camera with a digital minicomputer for the purpose of imaging of bronchial blood flow in various lung diseases, and as application of dual radioisotope techniques, other imagings such as tumor imaging with 197 HgCl 2 or 67 Ga-citrate and/or perfusion imaging with sup(99m)Tc-MAA, were performed simultaneously in patients remaining the same position, too. The image as a iso-count map extracted out of the image of 197 HgCl 2 , 67 Ga-citrate or sup(99m)Tc-MAA, was superimposed to the brightness image of RI-angiogram (aortic phase). By these procedures, the image of bronchial blood flow were obtained in some patients with lung cancer, pulmonary tuberculosis, lung abscess, and chronic bronchitis. The dual radioisotope techniques using RI-angiography and the other imaging were useful to make isotope diagnosis of lung diseases more reliable, and the image superimposition methods using RI-angiogram and the image of tumor of perfusion, were useful to improve anatomic orientation of the former.

    Bronchial asthma is characterized by chronic airway inflammation. The primary goal of treatment of asthma is to maintain the state of control. According to the Japanese guidelines (JGL2012), long-term management consists of 4 therapeutic steps, and use of inhaled corticosteroids (ICS) is recommended at all 4 steps. Besides ICS, inhalation of long-acting β2-agonist (LABA) is also effective. Recently, omalizumab (a humanized antihuman IgE antibody) can be available for patients with severe allergic asthma. Although there is no specific strategy for preoperative treatment of patients with asthma, preoperative systemic steroid administration seemed to be effective to prevent asthma attack during anesthesia. The most common cause of chronic bronchitis is smoking. Even the respiratory function is within normal limits, perioperative management of patients with chronic bronchitis is often troublesome. The most common problem is their sputum. To minimize perioperative pulmonary complication in these patients, smoking cessation and pulmonary rehabilitation are essential. It is known that more than 1 month of smoking cessation is required to reduce perioperative respiratory complication. However, even one or two weeks of smoking cessation can decrease sputum secretion. In summary, preoperative optimization is most important to prevent respiratory complication in patients with bronchial asthma or chronic bronchitis.

  9. Successful Treatment of Bronchoesophageal Fistula With Esophageal and Bronchial Stenting

    Full Text Available Bronchoesophageal fistula is reported in 5-10% of patients with esophageal cancer. In most of these cases, the insertion of a single stent, either a tracheobronchial or an esophageal stent, is sufficient to seal off the fistula. In this case we describe a 67-year-old man with esophageal cancer and complications of bronchoesophageal fistula, which resulted in repeated pneumonia and acute respiratory failure. Initially, two expandable metallic membranous esophageal stents were placed to cover the fistula. However, the esophageal stent failed to stop the air leak and dislodged into the stomach. Thereafter, a bronchial stent was placed at the right intermediate bronchus and successfully stopped the air leak. The patient was then weaned from the ventilator 1 week after the insertion of a bronchial stent. In conclusion, stenting in both the esophagus and airways should be considered when both are severely invaded by malignancy, when the airway is compressed, or when the fistula is insufficiently sealed by an esophageal stent.

    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.

    Full Text Available Introduction: Hamartomas involving the floor of the fourth ventricle and cerebellum are rare, but can be associated with medically recalcitrant hemifacial spasm. These lesions present early in the neonatal or infantile period and respond well to surgical excision. Case Report: A 3-month-old white male presented with recurrent left hemifacial spasm, left eye deviation, and absent movement of the extremities. The patient was found to have a left eccentric lesion in the floor of the fourth ventricle and cerebellum. The patient showed no improvement with medical therapy by 6 months of age. He was taken to the operating room for suboccipital craniotomy and removal of the posterior arch of C1 followed by intralesional recording of epileptogenic activity and gross total resection of the lesion. After histologic analysis, the lesion was determined to be ectopic cerebral tissue consistent with a hamartoma. Postoperative MRI showed complete removal of the lesion, and the patient exhibited complete remission of his hemifacial spasm and associated symptoms. Conclusions: Hamartomas involving the floor of the fourth ventricle can present with hemifacial spasm and respond well to surgical excision. Keywords: Cerebellar, Seizure, Epilepsy, Hamartoma

    Patients presenting with infantile spasms, dysmorphic features, and periventricular nodular heterotopia may benefit from genetic copy number variation microarray, or whole-exome sequencing to identify candidate genes. This will allow personalized diagnosis and prognostication and the eventual understanding of single and combined gene functions in brain health and disease.

    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.

    To study bronchial reactivity and sensitivity with consideration of histamine, serotonin and catecholamines concentration in bronchial mucosa in patients with acute bronchitis (AB) as possible criteria of its becoming chronic. Before the treatment 116 patients with verified AB were examined using inhalation provocative tests (IPT) with histamine, serotonin and obsidian in increasing doses. Also, external respiration function was studied. IPT were repeated after the course of treatment. 87 of 116 AB patients exhibited high bronchial sensitivity and reactivity to inhalations of histamine, serotonin, obsidian. In parallel, there was a rise in the levels of histamine and serotonin and a fall in the level of catecholamines in bronchial mucosa (alveolar macrophages, lymphocytes, neutrophils, mast and APUD-cells). Changes in monoamines concentration in bronchial mucosa were relevant to activity of bronchial inflammation and the presence of obstructive syndrome. Persistent bronchial hyperreactivity to inhalations of histamine and obsidian along with high histamine levels and low level of catecholamines in alveolar macrophages, lymphocytes and mucus is a criterion of bronchitis transformation to chronic one.

    The isoprenoid pathway produces three key metabolites--digoxin (membrane sodium-potassium ATPase inhibitor and regulator of neurotransmitter transport), dolichol (regulator of N-glycosylation of proteins), and ubiquinone (free radical scavenger). The isoprenoid pathway was assessed in patients with bronchial asthma. The pathway was also assessed in patients with right hemispheric, left hemispheric, and bihemispheric dominance to find out the role of hemispheric dominance in the pathogenesis of bronchial asthma. The pathway was upregulated with increase in digoxin synthesis in bronchial asthma. There was an increase in tryptophan catabolites and a reduction in tyrosine catabolites in patients with bronchial asthma. The ubiquinone levels were low and lipid peroxidation increased in these patients. There was increase in dolichol and glycoconjugate levels and reduction in lysosomal stability in these patients. The cholesterol:phospholipid ratio was increased and glycoconjugate levels were reduced in the membranes of these patients. The patterns noticed in bronchial asthma were similar to those in patients with right hemispheric chemical dominance. Bronchial asthma occurs in right hemispheric chemically dominant individuals. Ninety percent of the patients with bronchial asthma were right-handed and left hemispheric dominant by the dichotic listening test. But their biochemical patterns were similar to those obtained in right hemispheric chemical dominance. Hemispheric chemical dominance is a different entity and has no correlation with handedness or the dichotic listening test.

    Objective: To evaluate the difference of internal diameter of bronchial artery in big lung cancer, small lung cancer, and normal lung with multiple slice CT. Methods: MSCT angiographies of 44 patients with lung cancer confirmed by pathology were retrospectively analyzed, and 29 patients were with big lung cancer (≥3 cm) and 15 patients with small lung cancer (<3 cm). Contrast enhanced helical thin slice CT scan was performed in all patients. Three dimensional images of bronchial artery were processed on workstation. The internal diameter of bronchial artery was measured. Results: The diameter of bronchial artery was (1.9±0.4) mm in 15 small lung cancer and (2.5±0.5) mm in 29 big lung cancer, respectively. There was a significant difference in internal diameter of bronchial artery between big and small lung cancer (P<0.05). Conclusion: Bronchial artery in lung cancer is dilated, and the dilation of bronchial artery in big lung cancer is more prominent than in small lung cancer. (authors)

    Relationship between cranial CT findings and prognosis at 12 months or more after birth was studied in 70 full-term (appropriate for date and large for date) infants who had spasm due to hypoxic ischemic encephalopathy following neonatal asphyxia. There was correlation between the prognosis of the infants and neonatal CT findings showing slight and marked low density areas in the brain parenchyma. However, it was sometimes difficult to estimate the prognosis when the low density area was moderate on CT. Therefore, follow-up CT at one and six months and one year after birth was required to examine changes in low density areas for the estimation of prognosis. The prognosis was unfavorable in cases of the disease accompanied by hemorrhage in the brain parenchyma or cerebral ventricle, persistent cerebral edema on neonatal CT, and low density areas in the atrophied brain by the follow-up CT. There was no consistent relationship between subarachnoid hemorrhage and the prognosis. (Namekawa, K.)

    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. © The Authors.

    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.

    The effects of continuous positive airway pressure (CPAP) treatment on the function of the lower airways are poorly understood. One of the methods used to determine the influence of positive pressure breathing on lower airways is the bronchial hyperreactivity test. Some authors report that CPAP increases bronchial hyperreactivity, while others report decreases. To assess the influence of CPAP treatment on bronchial reactivity and the effects of bronchial hyperreactivity on compliance to CPAP treatment. The study group consisted of 101 obstructive sleep apnea syndrome patients (88 men and 13 women) with a mean age of 51 ± 11 years, mean apnea-hypopnea index of 53 ± 20 and mean body mass index of 32.6 ± 5.4. Patients were randomly assigned to a treatment group that received 3 weeks of CPAP therapy (group 1) or to a nontreatment control group (group 2). Pulmonary function tests and the methacholine bronchial provocation test were performed at baseline and 3 weeks later. There were no statistically significant differences between treated and control groups in anthropometry and polysomnography variables. At baseline, bronchial hyperreactivity was found in 6 patients from group 1 and 5 patients from group 2. A significant increase in bronchial reactivity was observed after CPAP treatment. Log PC20M decreased from 1.38 ± 0.30 at baseline to 1.26 ± 0.50 (p bronchial hyperreactivity during CPAP treatment were characterized by significantly lower FEV1, FVC and MEF50 values. CPAP produces statistically significant bronchial hyperreactivity. However, there were no clinical symptoms and it is not necessary to withdraw previous therapies. Copyright © 2009 S.

    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.

    Epidemiological studies show that underground uranium miners have a radon progeny exposure-dependent increased risk for developing lung cancer. The odds ratio for lung cancer in uranium miners increase for all cumulative exposures above 99 Working Level Months. In addition, there is a strong multiplicative effect of cigarette smoking on the development of lung cancer in uranium miners. The purpose of this investigation was to determine whether or not early genetic changes, as indicated by genomic instability, can be detected in bronchial cells from uranium miners. Investigations of this nature may serve as a means of discovering sub-clinical disease and could lead to earlier detection of lung cancer and a better prognosis for the patient

    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.

    135 sportsmen and women, 55 girls, 80 boys, aged from 7 to 30 years, from various sports, who complained of bad tolerance of exertion were examined with an exercise test and isocapnic spontaneous hyperventilation. 61, about 45%, during a hyperventilation test had a fall of V.E.M.S. greater than or equal to 20%, showing bronchial hyperreactivity. After three tests, this fall index was greater than or equal to 50%. 68% of the positive responses were seen in boys and 2/3 of the subjects with a positive response were atopics. No other argument could be maintained from the questioning or clinical history to predict the positive or negative character of the hyperventilation (age, sporting level, symptoms, previous asthma or asthmatic, allergy). H.S.V.I. of the chests of a sporting population that complains of exertion intolerance, therefore allows verification of an H.R.B. assessment of its severity and to follow evolution after treatment.

    Full Text Available Background: Respiratory muscle strength can be decreased in patients with asthma; however, it is not well-documented whether a mild bronchial asthma disease can affect respiratory muscle strength in children and can be associated with higher presence of breathing difficulties. Objective: The main aim of the present study was to compare respiratory muscle strength between children with asthma and age-matched healthy children. The next aim of this study was to assess the incidence of decreased respiratory muscle strength in children with asthma and healthy children and assess the effect of decreased respiratory muscle strength on the incidence of breathing difficulties. Methods: Children with mild bronchial asthma (n = 167 and age-matched, healthy children (n = 100 were recruited into this study. Pulmonary function tests, maximal inspiratory (PImax and expiratory (PEmax mouth pressures and the incidence of breathing difficulty were evaluated in children with asthma and healthy controls. Results: The inspiratory muscle strength was similar between children with asthma and healthy children. Conversely, the expiratory muscle strength was lower in asthmatic children. There was a statistically significant difference between girls with asthma and healthy girls (PEmax = 81.7 ± 29.8% vs. 100.1 ± 23.7% of predicted, p < .001. PEmax was significantly higher in boys with asthma than in girls with asthma (PEmax = 92.9 ± 26.4 % vs. 81.7 ± 29.8% of predicted, p = .03. A higher incidence of breathing difficulties during physical activity (uphill walking, running, swimming was confirmed in children with asthma with lower respiratory muscle strength. Conclusions: There was a higher prevalence of decreased expiratory muscle strength in children with asthma; therefore, respiratory muscle strength should be tested in these children, especially in those who are symptomatic.

    Full Text Available Background: Coverage of the bronchial stumps (BSs with adjacent tissues can improve healing and reduce bronchial complications in complex thoracic surgery. There is no evidence for the application of human amnion allograft for prevention of air leak from the BS. The comparison of the amniotic membrane (AM and pleural patch for BS healing after lobectomy in dogs was our aim in this study. Materials and Methods: A total of eight males and females 12-24-month-old dogs between 17 and 22 kg body-weight were used in this study in 2010, Isfahan University of Medical Sciences. Animals were separated into two groups: group A (n = 4; amniotic membrane and group P (n = 4; pleural patch according to the BS closure technique performed. After lobectomy of the right middle lobe, the BS was closed, while a small bronchopleural fistula (BPF was created by inserting a catheter via edges of closed stump. Then, it was covered with a piece of AM3 × 3 cm in group A and with a pedicle graft of pleura in group P. Rethoracotomy was performed after 15 days of observation, and the BS was removed for histological examination. Histological healing was classified as complete or incomplete healing. Neoangiogenesis was measured by Von Willebrand expression using immunohistochemistry (IHC. Data were analyzed by SPSS version 15 using Fisher′s exact test, Mann-Whitney test, and T tests. Results: BPF complications were not seen during observation period. There was no significant difference in histological healing between two groups. Similarly, no significant difference was observed between the groups in terms of neoangiogenesis based on IHC examination (P value = 0.69. Conclusion: Human amnion allograft could be as effective as pleural patch for BS wrapping following pulmonary resections.

    The aim of this study is to evaluate the diagnostic performance of multidetector CT angiography (CTA) in depicting bronchial and non-bronchial systemic arteries in patients with haemoptysis and to assess whether this modality helps determine the feasibility of angiographic embolisation. Fifty-two patients with haemoptysis between January 2010 and July 2011 underwent both preoperative multidetector CTA and digital subtraction angiography (DSA) imaging. Diagnostic performance of CTA in depicting arteries causing haemoptysis was assessed on a per-patient and a per-artery basis. The feasibility of the endovascular treatment evaluated by CTA was analysed. Sensitivity, specificity, and positive and negative predictive values for those analyses were determined. Fifty patients were included in the artery-presence-number analysis. In the per-patient analysis, neither CTA (P=0.25) nor DSA (P=1.00) showed statistical difference in the detection of arteries causing haemoptysis. The sensitivity, specificity, and positive and negative predictive values were 94%, 100%, 100%, and 40%, respectively, for the presence of pathologic arteries evaluated by CTA, and 98%, 100%, 100%, and 67%, respectively, for DSA. On the per-artery basis, CTA correctly identified 97% (107/110). Fifty-two patients were included in the feasibility analysis. The performance of CTA in predicting the feasibility of angiographic embolisation was not statistically different from the treatment performed (P=1.00). The sensitivity, specificity, and positive and negative predictive values were 96%, 80%, 98% and 67%, respectively, for CTA. Multidetector CTA is an accurate imaging method in depicting the presence and number of arteries causing haemoptysis. This modality is also useful for determining the feasibility of angiographic embolisation for haemoptysis.

    1994-01-01

    Full Text Available Plasma from bronchial asthma patients and healthy controls was investigated for the content of lipoxygenase products. After lipid extraction using SEP-PAK C18 Cartridges, the lipoxygenase products were measured by Enzyme-Immunoassay. Elevated chemotactic B4 was found in plasma from asthmatic patients with mean value (483±75 pmoUL, while the mean value in normal healthy donors was (140± 12.1 pmol/L (M±SE. The levels of spasmogenic cysteinyl containing leukotrienes were also very high in the bronchial asthma patients. Elevations of leukotriene B4 and cysteinyl containing leukotrienes were detected during attacks of bronchial asthma. These results suggest that leukotriene B4 may be important in the pathogenesis of bronchial asthma and confirmed that peptidoleukotrienes playa role as chemical mediators during the asthmatic attack.

    Bronchial tuberculosis is a common complication of pulmonary tuberculosis. The present report is to investigate and analyze the indication and efficacy of surgical treatment of bronchial stricture due to severe endobronchial tuberculosis, when the drug and endoscopic treatment were no effect. Reviewed the clinical-pathological records documenting the surgical outcomes in 36 bronchial stricture due to severe endobronchial tuberculosis who underwent lobectomy or pneumonectomy enrolled in our hospital between January 2000 and February 2016. Pneumonectomy in 8 cases, lobectomy in 23 cases, sleeve resection in 5 cases. No intraoperative or early postoperative death occurred. Six patients developed complications. All 6 cases recovered well after treatment. Surgical treatment is still the recommended treatment modatity for bronchial stricture caused by endobronchial tuberculosis due to its good results. It should be performed in time when the drug and intraluninal treatment were no effect for avoiding of being progeressed.

    2016-02-01

    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.

    Although it has been postulated that inflammatory cells cause the bronchial hyperresponsiveness which is diagnostic of asthma, until recently there has been little direct evidence of such a link. We have recently shown that calcium ionophore-activated human neutrophils and eosinophils can induce a state of human airway hyperresponsiveness in vitro. In this study we have shown that the anti-inflammatory agent nedocromil sodium, 10(-7) M, inhibited the hyperresponsiveness induced by products released from ionophore activated neutrophils but did not inhibit the release of leukotriene B4 from the same cells. Neutrophil-induced bronchial hyperresponsiveness was also inhibited by pre-treatment of the bronchial tissues with a thromboxane A2 and prostaglandin receptor antagonist, GR32191, 10(-7) M. These findings indicate that cyclooxygenase products are involved in bronchial hyperresponsiveness induced by inflammatory cell products in vitro and that their release can be inhibited by nedocromil sodium.

    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.

    2010-02-01

    Based on the retrieval of literatures in recent fifteen years, the time factors in the acupoint sticking therapy for the bronchial asthma are analyzed and compared in terms of the stage classification of patients, timing selection of acupoint sticking therapy and medication application, and times of application. The acupoint sticking therapy is mostly practiced during remittent stage of bronchial asthma; the timing selection is mostly during the hottest period of summer, the timing selection in certain cases is the coldest period of winter or any day; the duration of medication application is not consistent; therefore, the effectiveness of these cases is different. It may be that the ef fectiveness is proportional to the times and courses of acupoint sticking therapy for the bronchial asthma. In the future, the scientific designs which involve time factor are needed to elucidate the importance of time factor in acupoint sticking therapy for the bronchial asthma.

    Pulmonary hemodynamic disorders depend on the inflammatory phases and severity of the obstructive syndrome. However, the effect of asthma bronchial obstruction on the state of peripheral hemodynamics remains insufficiently known. To study the effects of airway obstruction on skin blood flow parameters and its regulatory systems in patients with persistent atopic bronchial asthma in the remission state. A comparative study of the skin peripheral blood flow in patients with bronchial asthma with severe airway obstruction (1st group) and without obstruction (2nd group) was conducted. 20 patients with confirmed diagnosis of atopic asthma of 50–74 years old participated in the study. All patients received basic therapy in a constant dosing of high doses of inhaled glucocorticosteroids/long-acting beta-2-agonists. The control group included 20 healthy volunteers without evidence of bronchial obstruction. The study lasted for 3 months. The forced expiratory volume in 1 s (FEV1) was used to evaluate the bronchial obstruction by spirometry technique. Skin blood perfusion changes were recorded by laser Doppler flowmetry at rest and in response to short-term local ischemia. Registered peripheral blood flow signals were examined using the amplitude temporal filtering in five frequency intervals to identify the functional features of the peripheral blood flow regulation systems. Consistent two-fold decrease of the oscillation amplitudes was found in the neurogenic interval at rest (p=0.031), as well as in the myogenic (p=0.043; p=0.031) and endothelial intervals (p=0.037; p≤0.001) both at rest and during the postocclusive reactive hyperemia respectively in the 1st group of patients with bronchial obstruction (FEV1 obstruction, FEV1 >80%) in comparison to control subjects. The presence of bronchial obstruction has a significant impact on the changes of the amplitudes of skin blood flow oscillations in patients with bronchial asthma in the myogenic, neurogenic and endothelial

    Benign bronchial stenosis is managed by surgical or bronchoscopic methods. Although surgical approach is definitive, it is technically demanding and is costlier than bronchoscopic treatment. Here, we report the case of a 27-year-old female patient with symptomatic benign bronchial stenosis of the left main bronchus. The stenosis was dilated successfully through a fibreoptic bronchoscope by electrocautery followed by balloon bronchoplasty and application of mitomycin-C. On follow up, there was no evidence of re-stenosis.

    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.

    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 1 % of 70/84 (83.3%) patients was above 70. The FEV 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 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

    We report a case in a neonate of concurrent bronchial atresia and bronchogenic cyst. An accurate, noninvasive, preoperative diagnosis of this unusual combination of anomalies was made by ultrafast computed tomography (UFCT). This case supports the hypothesis that bronchial atresia results from an event occurring in the 5th-6th week of embryological development, rather than after the 16th week as previously believed.

    Obstructive sleep apnea syndrome (OSA) is associated with systemic and upper airway inflammation. Pharyngeal inflammation has a potential role in upper airway collapse, whereas systemic inflammation relates to cardiovascular morbidity. However, the presence of an inflammatory involvement of lower airway has been poorly investigated. The aim of the study was to demonstrate an inflammatory process at the bronchial level in patients with OSA and to analyze effects of continuous positive airway pressure (CPAP) application and humidification on bronchial mucosa. The study was conducted by using sequential induced sputum for cell analysis and IL-8 production, nitric oxide exhalation measurement, and methacholine challenge before and after CPAP. Bronchial neutrophilia and a high IL-8 concentration were observed in untreated OSA compared with controls (75% +/- 20% vs 43% +/- 12%, P Obstructive sleep apnea syndrome is associated with bronchial inflammation. Our data demonstrate CPAP effect on the development of AHR, possibly facilitated by the pre-existing inflammation. Both issues should be evaluated during long-term CPAP use. Results showing a spontaneous bronchial inflammation in OSA and the development of a CPAP-related AHR require a long-term follow-up to evaluate consequences on chronic bronchial obstruction.

    2009-01-01

    One of more frequent reasons for hospitalizations concerning infants and small children are obstructive bronchitis. Great prevalence of bronchial tree obturation during infancy and in small children is a result of anatomical and functional differences of airways and immunological differences that occur in infants and small children. The most frequent cause of bronchial tree obturation is infection induced by viruses, rarely by bacteria. Recurrences of bronchial tree obturation are observed in some patients. Obturation recurrences can be caused by number of diseases that appear during infancy and in small children, for example cystic fibrosis of the pancreas. Also the presence of foreign body in the airways, immotile cilia syndrome, immunological disturbances, innate anomalies of the respiratory system and the circulatory system and bronchial asthma can result in obturation recurrences. Various clinical criteria are established and new markers of allergic inflammation are searched in view of difficulties to diagnose bronchial asthma in the youngest children. There are no unequivocal rules to diagnose bronchial asthma in infants and small children despite these searches.

    To evaluate the characteristics of tracheal and main bronchial diverticula in relation with emphysema. A total of 967 CT images were reconstructed with 1.25 mm axial images over 2 months. The incidence, size, number, and location of the tracheal and main bronchial diverticula were analyzed using 3D medical software (Seoul, Korea). The incidence of emphysema and the relationship between emphysema and the size of the diverticula were analyzed. In total, 50 patients (5.1%) showed tracheal diverticula in the right posterolateral wall. In addition, 51 patients (5.2%) showed 89 (9.4%) main bronchial diverticula in the inferior wall, while 68 (72%) showed diverticula in the left posterolateral wall. Tracheal diverticula (6.4 {+-} 5.0 mm, 1.0 {+-} 0.2) were larger and fewer than the main bronchial diverticula (2.1 {+-} 2.0 mm, 1.8 {+-} 1.6) (p<0.05). Moreover, tracheal diverticula (10.3 {+-} 7.4 mm) with emphysema in 13 patients (26%), were larger than those without emphysema (5.1 {+-} 3.0 mm) (p<0.05). On thin-section MDCT, the rates of incidence for tracheal and main bronchial diverticula are about 5%, respectively. Tracheal diverticula in the right posterolateral wall are smaller and fewer than the main bronchial diverticula, which are located primarily in the inferior wall of the left bronchus. Tracheal diverticula with emphysema are larger than those without emphysema.

    A 51-year-old man with a resuscitation episode was referred to our hospital. Coronary angiography revealed a focal spasm overlapped with organic stenosis where a bare metal stent was implanted. Acetylcholine (ACh) provocation test did not induce chest pain. It revealed no discernible ST-T changes but unmasked a J wave at the end of the QRS complex, which was associated with short-coupled repetitive premature ventricular beats. A J wave reportedly appears immediately before the onset of ventricular fibrillation caused by vasospastic angina. However, a J wave observed newly after a coronary spasm provocation test using ACh without ST-T changes is informative when considering the mechanisms of the J wave.

    Full Text Available Duodenal-bronchial fistulas are very uncommon, even among the already rare subgroup of abdominal-bronchial fistulas. We describe a case of a woman with Crohn's disease who presented with shortness of breath and a productive cough who was found to have a duodeanl bronchial fistula on computed tomography scan. We demonstrate with this case how these rare cases can lead to chronic lung aspirations and require multidisciplinary involvement.

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.

    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.

    A long-term physical exercise program was established for a large number of children with bronchial asthma. Asthmatic children were first taught to swim on their backs to prevent breathing problems customary for beginners using other strokes. They concurrently participated in gymnasium exercises, and the program was later completed with outdoor running. Program effectiveness was evaluated by monitoring asthmatic symptoms, changes in medication, and changes in the activity and physical fitness of the children. Data collected from 121 children showed that during the first year in the program the number of days with asthmatic symptoms decreased in a large majority of the patients while medication was decreased. School absenteeism and hospitalization dropped markedly. Parental evaluation of the children indicated much improvement in 51.2%, improvement in 40.5%, unchanged condition in 7.4%, and deterioration of general health was only reported in one child (0.8%). The same extent of improvement continued during the second year. The Cooper test was applied for the first time to such an exercise program and indicated that the participating asthmatic children performed as well as a control group of nonasthmatic children, and the cardiovascular efficiency of the asthmatics was actually better.

    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

    This study aimed to assess the feasibility of quantification of bronchial dimensions at MDCT using dedicated software (BronCare). We evaluated the reliability of the software to segment the airways and defined criteria ensuring accurate measurements. BronCare was applied on two successive examinations in 10 mild asthmatic patients. Acquisitions were performed at pneumotachographically controlled lung volume (65% TLC), with reconstructions focused on the right lung base. Five validation criteria were imposed: (1) bronchus type: segmental and subsegmental; (2) lumen area (LA)>4 mm 2 ; (3) bronchus length (Lg) > 7 mm; (4) confidence index - giving the percentage of the bronchus not abutted by a vessel - (CI) >55% for validation of wall area (WA) and (5) a minimum of 10 contiguous cross-sectional images fulfilling the criteria. A complete segmentation procedure on both acquisitions made possible an evaluation of LA and WA in 174/223 (78%) and 171/174 (98%) of bronchi, respectively. The validation criteria were met for 56/69 (81%) and for 16/69 (23%) of segmental bronchi and for 73/102 (72%) and 58/102 (57%) of subsegmental bronchi, for LA and WA, respectively. In conclusion, BronCare is reliable to segment the airways in clinical practice. The proposed criteria seem appropriate to select bronchi candidates for measurement. (orig.)

    Full Text Available In the past ten years, 45 cases of infantile spasm treated in our center. From these patients, 15 cases received only steroid, other 15 cases only clonazepam, and the rest, a combination of clonazepam and steroid. All patients were observed for two years. This is a retrospective study, the data being extracted from patients record. A number of patients were treated in ambulatory and the others were patients of the hospital. The result of comparison of optimal control of seizures are as follow: 1 In only steroid group 27 percent of the patients were free of seizure, 2 In only clonazepam group 28 percent showed no seizure, 3 in combined clonazepam and steroid group 39% were seizure-free. Based on this trial we believe that treatment of infantile spasm with combined steroid and clonazepam is better than any of them alone. Considering these results, we believe that the treatment of infantile spasm with a combination of steroid and clonazepam is preferable to these drugs.

    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.

    Hemifacial spasm (HFS) is a common movement disorder, but its prevalence in different populations has not been elucidated. We reviewed all patients with HFS currently followed at the Baylor College of Medicine Movement Disorders Clinic and compared their demographic and clinical data with a control group of patients with cranial-cervical dystonia (CD). In contrast to patients with CD (N=145, mean age 48.64±13.61 years), of whom 117 (80.69%) were Caucasians, 13 (8.97%) Hispanic, 10 (6.90%) African-American, and 5 (3.45%) were of Asian origin, there were 81 (61.36%) Caucasians, 24 (18.18%) Hispanic, 13 (9.85%) African-Americans, and 14 (10.61%) Asians in the HFS group (N=132, mean age 49.33±13.25). Although there was no statistical difference in the age and gender distribution between the two groups, the frequency of Asians in HFS group was 3.1 times higher than that in CD group (Pmovement disorder.

    Compositional differences in the bronchial bacterial microbiota have been associated with asthma, but it remains unclear whether the findings are attributable to asthma, to aeroallergen sensitization, or to inhaled corticosteroid treatment. We sought to compare the bronchial bacterial microbiota in adults with steroid-naive atopic asthma, subjects with atopy but no asthma, and nonatopic healthy control subjects and to determine relationships of the bronchial microbiota to phenotypic features of asthma. Bacterial communities in protected bronchial brushings from 42 atopic asthmatic subjects, 21 subjects with atopy but no asthma, and 21 healthy control subjects were profiled by using 16S rRNA gene sequencing. Bacterial composition and community-level functions inferred from sequence profiles were analyzed for between-group differences. Associations with clinical and inflammatory variables were examined, including markers of type 2-related inflammation and change in airway hyperresponsiveness after 6 weeks of fluticasone treatment. The bronchial microbiome differed significantly among the 3 groups. Asthmatic subjects were uniquely enriched in members of the Haemophilus, Neisseria, Fusobacterium, and Porphyromonas species and the Sphingomonodaceae family and depleted in members of the Mogibacteriaceae family and Lactobacillales order. Asthma-associated differences in predicted bacterial functions included involvement of amino acid and short-chain fatty acid metabolism pathways. Subjects with type 2-high asthma harbored significantly lower bronchial bacterial burden. Distinct changes in specific microbiota members were seen after fluticasone treatment. Steroid responsiveness was linked to differences in baseline compositional and functional features of the bacterial microbiome. Even in subjects with mild steroid-naive asthma, differences in the bronchial microbiome are associated with immunologic and clinical features of the disease. The specific differences identified

    Objective: To explore DSA findings curative measures and effects of bronchial arterial embolization (BAE)of bronchiectasis with massive hemoptysis. Methods: 35 patients with massive hemoptysis due to bronchiectasis were performed selective bronchial arterial DSA and BAE referring to image data of chest plain film and CT. Embolic materials were polyvinyl alcohol (PVA)and/or gelatinum sponge particles. Curative effects were followed-up for 3 months to 3 years. Results: (1)DSA revealed bronchial artery as being the only abnormal vessel accounted for 74.3%, bronchial artry combined with nonbronchial systemic artery as 22.9% and only non-bronchial artery involved 2.9%. Abnormal vessel number was 1-5 (mean 1.8) per case; Direct and indirect bleeding sign was displayed as 25.7% and 100% respectively. (2)Curative and embolization effects were shown as 61 target vessels of 34 patients being embolized and total effective rate reaching 85.3%; of which 16 cases were adopted super-selective technique, 1 case was failure of stopping bleeding for two times within 3 days, 4 cases recurred within 3 months and 2 cases recurred over 3 months; with recurrent rate of 20.6%, but no serious complications such as spinal cord injury. Conclusions: DSA examination and selective BAE of bronchiectasis with massive hemoptysis could provide high positive angiographic features and reliable curative effect. (authors)

    In patients with post-tuberculosis bronchial stenosis (PTBS), the severity of bronchial stenosis affects the restenosis rate after the silicone stent is removed. In PTBS patients with incomplete bronchial obstruction, who had a favorable prognosis, the timing of stent removal to ensure airway patency is not clear. We evaluated the time for silicone stent removal in patients with incomplete PTBS. A retrospective study examined PTBS patients who underwent stenting and removal of a silicone stent. Incomplete bronchial stenosis was defined as PTBS other than total bronchial obstruction, which had a luminal opening at the stenotic segment on bronchoscopic intervention. The duration of stenting was defined as the interval from stent insertion to removal. The study included 44 PTBS patients and the patients were grouped at intervals of 6 months according to the duration of stenting. Patients stented for more than 12 months had a significantly lower restenosis rate than those stented for less than 12 months (4% vs. 35%, P = 0.009). Multiple logistic regression revealed an association between stenting for more than 12 months and a low restenosis rate (odds ratio 12.095; 95% confidence interval 1.097-133.377). Moreover, no restenosis was observed in PTBS patients when the stent was placed more than 14 months previously. In patients with incomplete PTBS, stent placement for longer than 12 months reduced restenosis after stent removal.

    Nuclear angiocardiography with sup(99m)TcO 4 - was performed for the purpose of the delineation of the systemic perfusion in various lung diseases, using a scintillation camera with a digital minicomputer system. The images of the bronchial blood flow were obtained in cases with primary lung cancer, pulmonary tuberculosis, lung abscess, bronchiectasis and chronic bronchitis. The fair images of the bronchial blood flow were taken in cases of peripheral type, adenocarcinoma and primary foci of atelectatic type in primary lung cancer. The grade of delineation of the bronchial blood flow and vascularity of bronchial artery in foci of primary lung cancer were correlative to the grade of accumulation of 197 HgCl 2 , respectively. The joint use of nuclear angiocardiography and other imagings such as tumor or perfusion one was useful for evaluation of the pulmonary and systemic circulation, and that made isotope diagnosis of primary lung cancer more reliable too. The image as a isocount map extracted out of the image of 197 HgCl 2 or sup(99m)Tc-MAA, was superimposed to the brightness image of the nuclear angiocardiogram (aortic phase). This image superimposition methods were valuable to improve anatomic orientation of the nuclear angiocardiogram. The delineation of the bronchial blood flow on the subtraction image, which obtained from the two time-different images in aortic phase of the nuclear angiocardiogram, was better than that of the original images.

    The aim was to display variations of right bronchial tree. The bronchial tree images of 238 patients were reconstructed using the postprocessing technique of CT. We revealed four cases rare bronchial branching patterns of right superior lobe. 1 case was referred to as tracheal bronchus. In 1 case, B1 was located in the place of the right superior lobar bronchus and B2 + 3 arose from the right merge of the IB. In 1 case, the right superior lobar bronchus has only two divisions for B1 and B3, and the bronchus B2 arose from the right merge of the IB. In 1 case, B1 branched into four bronchi. We revealed 15 cases of rare bronchial branching patterns of right inferior lobe. In nine cases, the basal trunk bronchus bifurcated into B7 + 8 and B9 + l0. In three cases, B8 branched from the basal trunk bronchus before B7. In two cases, basal trunk bronchus bifurcated into B7 + 8 + 9 and B10. In 1 case, the basal trunk bronchus bifurcated into the common stem of B7 + 10 and B8 + 9. Variations of right bronchial tree were displayed in the present study. This information may have important implications for diagnosis of symptomatic patients and performing certain procedures, including bronchoscopy, endotracheal intubation, and lung resection.

    Stimulation to bronchial mucosa is one of the major risk factor of asthma attack. When patients receive surgical intervention and general anesthesia, they are always exposed to stimulation to bronchial mucosa. Prevention method of bronchial asthma attack during surgical intervention is not established yet. We investigated that clinical course of patients with bronchial asthma who received general anesthesia and surgical intervention. Seventy-six patients with bronchial asthma were received general anesthesia and surgical intervention from 1993 to 1998. Twenty-four patients were mild asthmatic patients, 39 were moderate asthmatic patients and 13 were severe asthmatic patients. Preoperative treatment for preventing asthma attack was as follows; Eight patients were given intravenous infusion of aminophylline before operation. Fifty-two patients were given intravenous infusion of aminophylline and hydrocortisone before operation. Three patients were given intravenous infusion of hydrocortisone for consecutive 3 days before operation. Thirteen patients were given no treatment for preventing asthma attack. One patient was suffered from asthma attack during operation. She was given no preventing treatment for asthma attack before operation. Three patients were suffered from asthma attack after operation. No wound dehiscence was observed in all patients. To prevent asthma attack during operation, intravenous infusion of steroid before operation is recommended, when patients with asthma receive general anesthesia and surgical intervention.

    Omalizumab therapy of non-atopic asthmatics reduces bronchial mucosal IgE and inflammation and preserves/improves lung function when disease is destabilised by staged withdrawal of therapy.18 symptomatic, non-atopic asthmatics were randomised (1:1) to receive omalizumab or identical placebo treatment in addition to existing therapy for 20 weeks. Bronchial biopsies were collected before and after 12-14 weeks of treatment, then the patients destabilised by substantial, supervised reduction of their regular therapy. Primary outcome measures were changes in bronchial mucosal IgE + cells at 12-14 weeks, prior to regular therapy reduction, and changes in lung function (forced expiratory volume in 1 s) after destabilisation at 20 weeks. Quality of life was also monitored.Omalizumab but not placebo therapy significantly reduced median total bronchial mucosal IgE + cells (pomalizumab treated patients, with significant differences in absolute (p=0.04) and % predicted forced expiratory volume in 1 s (p=0.015).Omalizumab therapy of non-atopic asthmatics reduces bronchial mucosal IgE + mast cells and improves lung function despite withdrawal of conventional therapy.

    We investigated the capabilities of an endo-cytoscopy system (ECS) that enables microscopic imaging of the tracheobronchial tree during bronchoscopy, including normal bronchial epithelium, dysplastic mucosa and squamous cell carcinoma. The newly developed ECS has a 3.2 mm diameter that can be passed through the 4.2 mm working channel of a mother endoscope for insertion of the ECS. It has a high magnification of 570× on a 17 in. video monitor. Twenty-two patients (7 squamous cell carcinoma, 11 squamous dysplasia and 4 after PDT therapies) were underwent white light, NBI light and AFI bronchoscopy. Both abnormal areas of interest and normal bronchial mucosa were stained with 0.5% methylene blue and examined with ECS at high magnification (570×). Histological examinations using haematoxylin and eosin staining were made of biopsied specimens. Analyzed ECS images were compared with the corresponding histological examinations. In normal bronchial mucosa, ciliated columnar epithelial cells were visible. In bronchial squamous dysplasia, superficial cells with abundant cytoplasm were arranged regularly. In squamous cell carcinoma, large, polymorphic tumor cells showed increased cellular densities with irregular stratified patterns. These ECS images corresponded well with the light-microscopic examination of conventional histology. ECS was useful for the discrimination between normal bronchial epithelial cells and dysplastic cells or malignant cells during bronchoscopy in real time. This novel technology has an excellent potential to provide in vivo diagnosis during bronchoscopic examinations. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    The purpose of this study was to examine the relationship between the pulmonary distribution of inhaled radioaerosol, bronchial responsiveness, and lung function in children and adolescents. The participating subjects were divided into three groups: (1) 14 asthmatics with bronchial hyper-responsiveness (BHR), (2) five non-asthmatic subjects with BHR, and (3) 20 controls without BHR. Pulmonary distribution of [ 99 Tc m ] albumin radioaerosol, maximal expiratory flow when 25% of forced vital capacity remain to be exhaled (MEF 25 ), and bronchial responsiveness to inhaled histamine were measured. Twenty subjects (52%) has irregular central distribution and 19 subjects (48%) had regular distribution of radioaerosol in their lungs. No difference in distribution of radioaerosol was found between the three groups of children. The median MEF 25 among non-asthmatic subjects (80% predicted) was lower than that found in controls (92% predicted) but higher than that found in asthmatic subjects (55% predicted). A relationship was found between reduced flow at the peripheral airways, as indicated by MEF 25 and the degree of central distribution of radioaerosol. Furthermore, subjects with irregular central distribution of radioaerosol had an increase degree of bronchial responsiveness. In conclusion, children and adolescents who have flow rates in the peripheral airways or increased degree of bronchial responsiveness tend to have abnormal distribution of radioaerosols. (author)

    Introduction: Acute pulmonary emergencies in patient with cystic fibrosis (CF) can be found in cases of pneumothorax as well as hemoptysis. If the bleeding cannot be stopped by conservative methods, an embolization of the bronchial arteries should be done. Materials and Method: 11 patients were embolized using a combination of PVA particles and microcoils. Results: From January 1996 to June 2001 17 bronchial arteries in 11 patients were embolized. 7 patients suffered from chronical hemoptysis, 4 patients had an acute hemoptysis. In 4 patients both sides were embolized, in 3 patients only one side. The remaining 4 patients needed a second intervention, embolizing the other side. The primary embolizated bronchial artery was still closed in all 4 patients. In 1 patient the selective catheterization of a bronchial artery was not successful, thus the embolization could not be carried out. 1 patient died 5 days after the intervention due to a fulminant pneumonia (Pseudomonas aeruginosa) without recurrent bleeding. In two patients atypical branches from intercostal arteries feeding the bronchial arteries were detected and successfully embolized. All patients profited from the therapy, as bleeding could be stopped or at least be reduced. 3 patients suffered from back pain during or after intervention. There were no severe complications like neurological deficiencies or necroses. (orig.) [de

    Full Text Available The search for the new noninvasive and information methods to estimate the intensity of the inflammatory processes during the bronchial asthma is an important task for the modern medicine, pediatrics, in particular. We have examined 20 children, suffering from moderately severe bronchial asthma in remission. patients underwent the induction of the sputum by means of nail hypertonic solution, bronchoscopic examination along with the sampling of the lavage fluid and bronchial biopsy, cytometry of the induced sputum and bronchoalveolar lavage fluid, morphometric examination of the biopsy samples of bronchi walls, determination of the nitric oxide contents in the expired air. We revealed high self descriptiveness of the cytological characteristics of the induced sputum. High percentage of neutrophiles and eosinophiles in the induced sputum disclosed during remission of the bronchial asthma, as well as thickness increase of the basilemma, ratio distortion of the ciliated and cyathiform cells in the favor of the latter, especially along with the high nitric oxide contents in the expired air indicate the continuous persistence in the allergic respiratory inflammation.Key words: induced sputum, bronchial asthma, children.

    Recently, we described a model system which included corrections of high-resolution computed tomography (HRCT) bronchial measurements based on the adjusted subpixel method (ASM). To verify the clinical application of ASM by comparing bronchial measurements obtained by means of the traditional eye-driven method, subpixel method alone and ASM in a group comprised of bronchial asthma patients and healthy individuals. The study included 30 bronchial asthma patients and the control group comprised of 20 volunteers with no symptoms of asthma. The lowest internal and external diameters of the bronchial cross-sections (ID and ED) and their derivative parameters were determined in HRCT scans using: (1) traditional eye-driven method, (2) subpixel technique, and (3) ASM. In the case of the eye-driven method, lower ID values along with lower bronchial lumen area and its percentage ratio to total bronchial area were basic parameters that differed between asthma patients and healthy controls. In the case of the subpixel method and ASM, both groups were not significantly different in terms of ID. Significant differences were observed in values of ED and total bronchial area with both parameters being significantly higher in asthma patients. Compared to ASM, the eye-driven method overstated the values of ID and ED by about 30% and 10% respectively, while understating bronchial wall thickness by about 18%. Results obtained in this study suggest that the traditional eye-driven method of HRCT-based measurement of bronchial tree components probably overstates the degree of bronchial patency in asthma patients.

    Asthma has a higher prevalence in athlete populations such as Olympic athletes than in the general population. Correct diagnosis and management of asthma in athletes is important for symptom control and avoidance of doping accusations. However, few reports are available on asthma treatment in the athlete population in clinical practice. In this study, we focused on the clinical efficacy of inhaled corticosteroid (ICS) for asthma in a Japanese athlete population. The study subjects included athletes who visited the Niigata Institute for Health and Sports Medicine, Niigata, Japan for athletic tests and who were diagnosed with asthma on the basis of respiratory symptoms and positive results in a bronchodilator or bronchial provocation test such as exercise, hypertonic saline, or methacholine provocation. The athletes received ICS alone for at least 3 months, and the clinical background, sports type, and treatment efficacy were analyzed. The study population comprised 80 athletes (59 men and 21 women) with a median age of 16.0 years. Regarding sports type, 28 athletes engaged in winter sports (35%), 22 in endurance sports (27.5%), and 25 in indoor sports (31.3%). Although ICS is the primary treatment in athlete asthma, 16.3% of the athletes showed an unsatisfactory response to treatment according to the Global Evaluation of Treatment Effectiveness (GETE). These subjects were characterized by a decreased response to methacholine and lower values for FEV1/FVC and type 2 helper T cell (Th2)-associated biomarkers relative to responsive athletes. In multivariate analysis, FEV1/FVC and the logarithm to the base 10 of the IgE level were independently associated with the ICS response. These data suggest that ICS is effective for asthma in most athletes. However, certain asthmatic athletes are less responsive to ICS than expected. The pathogenesis in these subjects may differ from that of conventional asthma characterized by chronic allergic airway inflammation. Copyright

    The impulse oscillation system (IOS) allows easy measurement of respiratory system impedance (Zrs). The aim of this retrospective study was to evaluate the accuracy of IOS parameters obtained during methacholine challenge by comparison with "the gold standard" forced expiratory volume in the first second (FEV1). Measurements of FEV1 and resistances at 5 and 20 Hz, reactance at 5 Hz, impedance at 5 Hz and resonant frequency were performed in 227 children with suspected asthma, before and during methacholine challenge. Data were analyzed in the overall population and in three subgroups according to the final diagnosis: asthma (n = 72), chronic cough and nonspecific respiratory symptoms (n = 122), allergic rhinitis (n = 33). All IOS parameters changed significantly during the tests but only changes in X5 were significantly different between responders and nonresponders. Moreover, changes in IOS parameters were not correlated with changes in FEV1 apart from a weak correlation for X5. The receiver operating characteristic (ROC) curve for changes in X5 (to predict a 20% decrease in FEV1 showed a best decision level for a 50% decrease in X5 with a sensitivity of 36% and a specificity of 85%. Results were not different in the asthma group. The accuracy of measurements by IOS during methacholine bronchial challenge in children was not suitable when compared with FEV1 . It could be assumed that spirometry and IOS, while both providing indirect indices of airway patency, are exploring different mechanisms, each with its own methodological potentials and limitations.

    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 sequencing. 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 show 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. - Highlights: • Tungsten (W) induces cell transformation and increases migration in vitro. • W increases xenograft growth in nude mice. • W altered the expression of cancer-related genes such as those involved in leukemia. • Some of the dysregulated leukemia genes include, CD74, CTGF, MST4, and HOXB5. • For the first time, data is presented that demonstrates tungsten's carcinogenic potential.

    2013-03-01

    Full Text Available On the base of a complex examination of 215 schoolchildren who suffer bronchial asthma, there have been established that clinical manifestations of severity of bronchial obstructive syndrome during disease exacerbation do not depend on acetylating status. However, a homozygosity on both alleles of the glutathione transferase gene (GSTT1+M1+ has been connected to greater severity of asthma attacks, while a lack of the T-allele in children with slow acetylating phenotype has been associated with more frequent use of systemic corticosteroids and somewhat better results of airways obstruction relief therapy. Occurrence of GSTT1+M1+ genotype in patients with accelerated processes of acetylation significantly increased the risk of the inefficiency of bronchial obstruction relief therapy (odds ratio 12.4, relative risk — 6.4, the absolute risk — 50 %.

    Full Text Available Introduction. The course of bronchial asthma in children is often accompanied by gastrointestinal (GI diseases associated with H.pylori infection. The presence of H.pylori leads to the activation and maintenance of inflammatory process with release of cytokines and mediators of inflammation and subsequent systemic effects. Objective: to study the peculiarities of interferon gamma (IFN-γ and interleukin (IL-4, -5 and -13 production as markers of allergic inflammation severity in children with bronchial asthma infected with H.pylori. Materials and methods. There were examined 120 children with bronchial asthma aged 6 to 18 years. Identification of H.pylori was carried out with the help of brea­thing Helic-test (LLC AMA, Russia. Serum concentrations of IFN-γ and IL‑4, -5 and -13 were determined by enzyme-linked immunoassay (Diaclone test-kits, France before and 7 days after the end of treatment for GI pathology. Statistical processing was performed using the methods of variation statistics implemented in the software package Statistica 6.1. Results. 78 children with bronchial asthma were diagnosed with GI disease, including 37 cases associated with H.pylori infection. To study the influence of H.pylori on the course of bronchial asthma, children were divided into 3 groups: I group — 37 children with bronchial asthma and GI pathology, infected with H.pylori, II — 41 H.pylori-negative children with bronchial asthma and GI pathology, III — 42 H.pylori-negative children with bronchial asthma without GI disorders. Duration of bronchial asthma in group I was 7.80 ± 0.17 years, in II — 5.90 ± 0.26 years, in group III — 3.90 ± 0.48 years (p < 0.05. The presence of H.pylori infection in children with bronchial asthma was accompanied by lower concentrations of IFN-γ compared to children of group II (8.47 ± 0.14 pg/ml and 9.69 ± 0.32 pg/ml, respectively, p < 0.05.

    Full Text Available There were performed Doppler echocardiography investigations of functional state of the right heart in 42 children aged 5–17 years old in attack period of bronchial asthma of moderate to severe degree. Changes of intra-cardiac hemodynamics of the right heart in children in attack period of bronchial asthma were characterized by disturbance of systolic and diastolic function of the right ventricle and right atrium. Combined systolic-diastolic variant of the right ventricle dysfunction was typical for attack period of bronchial asthma in children and developed in 95.5 % of cases. Elevation of pressure in pulmonary artery was typical and significantly more often occurred in severe asthma attack, herewith pulmonary hypertension of the second degree predominated.

    Objective: To explore the role of endothelin and related cytokines (IL-5, IL-6, IL-8) in the development of bronchial asthma in pediatric patients. Methods: Plasma ET-1 (with RIA) and serum IL-5 (with ELISA), IL-6, IL-8 (with RIA) levels were measured in 42 pediatric patients with bronchial asthma and 30 controls. Results: The plasma ET-1 levels in the patients during acute attack (n=22) were significantly higher than those in patients during remission (n=20) as well as in controls (P 0.05). Levels of ET-1 were positively correlated with those of IL-5 (during attack, r=0.560, P<0.01; during remission, r=0.435, P<0.01). Conclusion: ET and the cytokines IL-5, IL-6, IL-8 participated in the pathogenesis of bronchial asthma through different mechanisms and dynamic determination of which could reflect the progression of the disease.

    Full Text Available The aim of our study was to determine the prevalence of anatomical variants of bronchial arteries using computed tomographic angiography in a population of northeastern Mexico. An observational, transversal, descriptive, comparative, retrospective study was performed using 139 imaging studies of Mexican patients in which we evaluated the following parameters from the left and right bronchial arteries: artery origin, branching pattern, arterial ostium, vertebral level of origin, diameter, and mediastinal trajectory. The anatomies of the bronchial arteries were similar in both genders, except distribution for vertebral origin level (p  0.006 and the diameter (p  0.013. Left and right arteries were similar, except for the mediastinal trajectory in reference to the esophagus (p<0.001 as well as the arterial diameter (p<0.001 and lumen diameter.

    Mutations in the X-linked cyclin-dependent kinase-like 5 (CDKL5) gene have been identified in patients with Rett syndrome, West syndrome, and X-linked infantile spasms sharing the common features of generally intractable early seizures and mental retardation. Disease-causing mutations are distributed in both the catalytic domain and in the large COOH terminus. In this report, we examine the functional consequences of some Rett mutations of CDKL5 together with some synthetically designed derivatives useful to underline the functional domains of the protein. The mutated CDKL5 derivatives have been subjected to in vitro kinase assays and analyzed for phosphorylation of the TEY (Thr-Glu-Tyr) motif within the activation loop, their subcellular localization, and the capacity of CDKL5 to interact with itself. Whereas wild-type CDKL5 autophosphorylates and mediates the phosphorylation of the methyl-CpG-binding protein 2 (MeCP2) in vitro, Rett-mutated proteins show both impaired and increased catalytic activity suggesting that a tight regulation of CDKL5 is required for correct brain functions. Furthermore, we show that CDKL5 can self-associate and mediate the phosphorylation of its own TEY (Thr-Glu-Tyr) motif. Eventually, we show that the COOH terminus regulates CDKL5 properties; in particular, it negatively influences the catalytic activity and is required for its proper sub-nuclear localization. We propose a model in which CDKL5 phosphorylation is required for its entrance into the nucleus whereas a portion of the COOH-terminal domain is responsible for a stable residency in this cellular compartment probably through protein-protein interactions.

    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)

    Bronchial artery embolization has been effective in the treatment of massive hemoptysis. The purpose of this study was to report the effectiveness of bronchial artery embolization in patients with chronic recurrent hemoptysis intractable to medical treatment. This study included 25 patients who were admitted for treatment of chronic recurrent hemoptysis with bronchial artery embolization. Chronic recurrent hemoptysis was defined as condition in tractable to medical treatment persistently and occurring over two times per two months The target vessels for embolization were selected in consideration of the results of aortography as well as the finding of chest radiography and bronchoscopy. After selective arteriography for embolization by using 5-French Simmons catheter, embolic agents(mainly polyvinyl alcohol(PVA) and additionally gelfoam and coils) were released through the catheter. The results of the embolization were assessed with review of medical records. The cases of the hemoptysis were pulmonary tuberculosis(n=12.48%), bronchiectasis(n=6.24%), aspergilloma(n=3.12%), chronic obstructive pulmonary disease(n=2.8%), chronic bronchitis(n=1.4%) and lung abscess(n=1.4%). Selective embolization was carried out in 49 sites(42 in bronchial artery and 7 in nonbronchial systemic collaterals). Early success rate within 2 months was 96%. After long-term follow up study (6-30 months, average 15 months), complete remission was 72%, partial remission 12% and recurrence 12% respectively. During and after embolization, major complications such as spinal cord injury or bronchial wall necrosis was not found. Minor complications were chest pain, shoulder pain and chilling sense, which were relieved spontaneously within a few days. High success rate and relatively low recurrence with no significant complication were achieved with bronchial artery embolization in the patients complaining of chronic recurrent hemoptysis.

    Full Text Available Bronchial asthma is one of the widespread chronic diseases of lungs. Immune mechanisms of disorder are one of the causes which lead to pathologic changes in lungs. The aim: to determine the clinical and immunologic effectiveness of pressure adaptation to the periodical hypobaric hypoxic stimulation of treatment of children with bronchial asthma of prepubertal and pubertal periods. In the present work there were observed the clinical and immunologic parameters of 129 children with the verified atopic bronchial asthma of different degree at the remission period before and after the course of pressure adaptation to the periodical hypobaric hypoxic stimulation in conditions of the medical hypobaric pressure chamber with many seats «Ural'1». Clinic effectiveness of hypobaric hypoxic stimulation revealed in continuation of remissions and diminishing of total numerical score of asthma degree. The positive dynamic indexes of cytokine profile was observed. It revealed in reduction of IL 1_, IL 4, IL 5, IL 18 levels and stimulated production of IFN - in blood serum. The course of hypobaric hypoxic stimulation has the positive impact on the named indexes of the patients with bronchial asthma and its intensity depends on the degree of disease and of the age of the child' patient. Thus the use of pressure adaptation to the periodical hypobaric hypoxic stimulation in treatment of children's with bronchial asthma led to the immunologic positive dynamics, especially of the children of prepubertal period. Determination of the immunologic indexes and the level of the cytokines can be used as the additional tests for the evaluation of the effectiveness of pressure adaptation to the periodical hypobaric hypoxic stimulation of children.Key words: bronchial asthma, periodical hypobaric hypoxic stimulation, cytokines, children.

    Objective: To investigate the establishment and bronchial arteriography of the models of canine lung cancer, and to facilitate further diagnosis and treatment of lung cancer. Methods: Twenty-two dogs were respectively administrated with 3 ml suspension of lipiodol-ultrafluid mixed with 3- methylcholanthrene (MCA) and diethylnitrosamine (DEN). The suspension was injected into the diaphragmic lobe of right lung with the co-axial catheter through endotracheal intubation. The dogs were randomly divided into 5 groups, group A (4 dogs), B (4), C (4), D (5), and E (5), which were sacrificed after observation for 1, 3, 6, 12, and 18 months, respectively. Then the image analysis and histopathologic examinations were carried out at different period. 5 dogs in group E were examined by bronchial arteriography. Results: Peribronchiolitis and atelectasis appeared at early stage (one month). Chronic granulomatous inflammation and fibrosis of lung tissue were gradually formed after 3 months. Proliferation of stem cells in bronchioles and atypical hyperplasia were found from 6 to 12 months. At last, the squamous carcinoma and bronchioloalveolar carcinoma were induced after 18 months. The lung cancer and precancerous lesion were found in 4 of 5 dogs at the 18 th month. The bronchial arteriography in the 5 dogs showed that 3 bronchial arteries were found as the supplying blood artery to the tumor. Conclusion: The suspension of lipiodol-ultrafluid mixed with MCA and DEN was exactly injected with the co-axial catheter through endotracheal intubation to establish the models of canine lung cancer. The inducible rate of the method was high and the location of lung cancer was accurate. It was affirmed that the blood supply artery of canine lung cancer was bronchial artery. Bronchial arteriography was of momentous significance to the diagnosis of early lung cancer. The establishment of the models of canine lung cancer was significant in the diagnosis and treatment of lung cancer. The models

    Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that involves medium- and small-sized arteries. PAN may affect any organ, and the presenting symptom of PAN varies depending on the organs affected. However, PAN generally spares the lung; thus, a report of PAN involving the bronchial artery is extremely rare, and hemoptysis has not been reported as the sole presenting symptom. Here, we report the case of a 39-year-old woman with hemoptysis who was diagnosed with PAN involving only the bronchial artery by angiography without involvement of the visceral arteries. Details of this case and a literature review are presented.

    Equivocal initial CT-based staging in 2 patients with hilar bronchial neoplasms was reassessed with retrospective ECG-gated Multislice-CT and optimized examination parameters prior to definition of treatment. An initially suspected irresectable T 4 tumor with mediastinal infiltration was downstaged to T 2 in one case, while tumor infiltration into the left atrium could be confirmed in the other case. In doubtful conditions, ECG-gated multislice CT with optimized examination parameters may be helpful for refined staging in patients with hilar bronchial neoplasma, thus possibly influencing treatment strategies.

    The local distribution of radon decay products deposited within bronchial bifurcations, particularly the formation of hot spots, may be more relevant for the determination of cellular doses in bronchial tissue than the commonly computed deposition efficiency, which is conceptually equivalent to the assumption of a uniform nuclide distribution. It is well known that the initial states of lung cancer in humans preferably occur in upper airways close to the cardinal location. In this study we use a recently developed geometric approach of a physiologically realistic bifurcation to demonstrate the site sensitivity of radon progeny deposition for two particle sizes, which are representative of the unattached and attached fraction of radon progeny

    In this work we did a sectional study of 31 asthmatic patients with several levels of disease severity, which were submitted to high resolution computed tomography of the thorax and spirometry, between the months of July, 1995 and August, 1997. The tomographic findings were correlated with the clinical classification of the patients and the most frequent tomographic findings were bronchial wall thickening, bronchial dilatation, air trapping, centrilobular opacities, cicatricial linear shadows, mucoid impaction, emphysema and atelectasis. In asthmatic patients of long duration we observed small airway disease and irreversible lesions as the predominant findings. In smoking patients there was no high frequency of emphysema. (author)

    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.)

    Bronchial rupture is an uncommon injury that presents clinically and radiologically with tension or non-tension pneumothorax, pneumomediastinum and subcutaneous emphysema caused by air leak and migration of free gas. Infradiaphragmatic gas has previously been demonstrated in mechanically ventilated patients with pneumomediastinum and is secondary to passage of air via anterior and posterior trans-diaphragmatic pathways. We present a case of bronchial rupture complicated by extensive infradiaphragmatic gas following mechanical ventilation that illustrates these pathways and some of the major radiographic signs associated with this injury Copyright (2004) Blackwell Publishing Asia Pty Ltd

    Cushing's syndrome occurred in 1-5% of cases of bronchial carcinoids. In this paper we describe a case of typical bronchial carcinoid in a nonsmoker young male with clinical manifestations mimicking a Cushing's syndrome. The patient performed chest radiograph and computed tomography. Fiberoptic bronchoscopy revealed the presence of an endobronchial mass occluding the bronchus intermedius. A rigid bronchoscopy was necessary for the conclusive diagnosis and for partial resection of the intraluminal tumor. Despite of the presence of Cushingoid features, the normal blood levels of ACTH and cortisol excluded the coexistence of a Cushing's syndrome. Copyright © 2016 The Authors.

    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.

    Bronchial atresia coexistent with intralobar pulmonary sequestration is so rare that only two cases have been reported in the literature. We report a case of congential bronchial atresia coexistent with intralobar pulmonary sequestation in a 51-year-old woman. Computed tomography showed the branching mass with hyperinflation of adjacent pulmonary parenchyma in the medial segment of the right middle lobe and a large thin-walled cystic mass with air-fluid levels in the medial basal segment of the right lower lobe. Selective inferior phrenic arteriography showed two aberrant arteries supplying the large cystic mass in the right lower lobe. The venous drainage was through the right pulmonary vein

    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.

    A high prevalence of bronchial hyperresponsiveness (BHR) and respiratory symptoms has been reported among competitive swimmers. From the 2002 Winter Olympics, BHR measurements or bronchodilator reversibility have been required for approved use of β2-agonists in sports. The first aim of this study was to evaluate the relationship among respiratory symptoms in young elite swimmers, eucapnic voluntary hyperpnea (EVH), and the inhaled dose of methacholine, causing a 20% decrease in forced expiratory volume in 1 s (FEV1; PD(20 methacholine)). The second aim of this study was to assess the repeatability of the EVH test. For this study, 15 male and 9 female adolescent elite swimmers, aged 15 to 25 yr, performed one PD(20 methacholine) test and two EVH tests in a randomized order. Dry air containing 5% CO2 was inhaled for 6 min with a target ventilation of ≥85% of maximum voluntary ventilation (minimum = 65%). PD(20 methacholine) ≤2 μmol and EVH with FEV1 reduction ≥10% were considered positive. Respiratory symptoms and medication were reported in the modified AQUA2008 questionnaire. Twenty swimmers (83%) reported respiratory symptoms, 13 (65%) of them had a positive provocation test. Fourteen (58%) had at least one positive test to either EVH or PD(20 methacholine); three had only one positive EVH test. One athlete had BHR without symptoms. The sensitivity of PD(20 methacholine) ≤2 μmol for respiratory symptoms was 50% versus 60% and 47.37% for the two EVH tests, respectively, and 75% for PD(20 methacholine) ≤4 μmol. The Bland-Altman plot of the two EVH tests showed a consistent distribution, with only one subject outside the limits of agreement. BHR was frequently found among adolescent competitive swimmers. PD(20 methacholine) ≤2 μmol and EVH ≥ 10% compared well, but PD(20 methacholine) ≤4 μmol had the highest sensitivity for respiratory symptoms. The EVH test has high repeatability but is very expensive and uncomfortable to perform.

    The artichoke is a perennial horticultural plant that belongs to the Compositae family. To present case studies of 2 vegetable warehouse workers who developed occupational rhinitis and bronchial asthma by sensitization to artichoke. Skin prick tests with common inhalants and foods were performed. Specific IgE to artichoke, Parietaria judaica pollen, and Olea europaea pollen extracts was measured by a specific IgE enzyme immunosorbent assay kit. Molecular mass of the allergens was studied by the sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) immunoblotting technique. Patients underwent a nasal challenge test, and one patient provided peak expiratory flow rate (PEFR) measurements in her workplace. In both patients, results of skin prick tests to artichoke were positive. Levels of specific IgE for artichoke were 0.68 kU/L in patient 1 and 2.14 kU/L in patient 2. The protein composition of the artichoke extract, studied by SDS-PAGE, showed that most bands ranged from 30 to 14 kDa. The IgE-binding bands with the serum samples of patient 1 showed apparent molecular masses of 56, 48, 38, 31, 27, 25, 16, and 15 kDa; however, the serum samples of patient 2 showed IgE bands of 21 and 19 kDa. Western blotting of artichoke extract showed a complete inhibition of IgE-binding bands when serum samples were preincubated with P. judaica pollen extract. Nasal challenge with artichoke extract triggered a peak nasal inspiratory flow decrease of 81% and 85% in patient 1 and patient 2, respectively. Finally, patient 1 recorded a PEFR decrease of up to 36% after exposure to artichoke in her workplace. SDS-PAGE immunoblotting inhibition performed for the artichoke extract showed a total disappearance of the specific IgE binding bands when serum samples were previously incubated with P. judaica pollen extract, thus establishing the existence of a serologic cross-reactivity between artichoke and P. judaica pollen.

  14. HDR intralumenal brachytherapy in bronchial cancer: review of our experience

    The main indications for brachytherapy in the treatment of endobronchial cancer are dyspnea. postobstructive pneumonia and atelectasis, cough and hemoptysis resulting from broncus obstruction by exophytic intralumenal tumor growth. High Dose Rate intralumenal brachytherapy (HDRBT) may be combined with external beam radiotherapy (EBRT), in particular as almost all tumors are too large for HDRBT alone. From January 1992 to September 1995 we treated 268 patients affected by bronchial cancer, with EBRT combined with HDRBT. All patients were staged as IIIa-IIIb-IV but KPS was >60 and expectancy of life > than 3 months. After bronchoscopy and Tc simulation we found that almost 10% of patients were downstaged. Treatment was always realized delivering 60 Gy to the tumour volume and 50 Gy to the mediastinal structures with EBRT. Brachytherapy was performed during the radiotherapy course. In 38 patients HDRBT was realized just one time, at the beginning of EBRT, with a dose of 10 Gy calculated at 1cm from the central axis of the catheter. In 47 HDRBT was performed twice (at the beginning and at the end of EBRT) with a dose of 7 Gy calculated at 1 cm from the central axis. From 1994 we started a 3 fractions protocol (Timing: days 1.15.30) with a dose of 5 Gy calculated at 0.5 cm from the axis. Of the 183 patients introduced in the protocol 170 received the three fractions of HDRBT and 13 were excluded from the study for personal or clinical reasons. In 97% of cases the application did not need general anesthesia; local anesthesia has been sufficient supplemented by some drug for sedation and coughing. Anyway both bronchoscopy and HDRBT (with anterior-posterior and lateral chest X-ray) are performed in the same shielded room without the necessity of displacing the patient. In almost 60% of treatments we used just one endobronchial applicator. In case of tumor involvement of the carina, two applicators were introduced. By this a larger tumor volume can be treated with adequate

    Purpose: To evaluate the dose–response relationship between radiation-induced atelectasis after stereotactic body radiation therapy (SBRT) and bronchial dose. Methods and Materials: Seventy-four patients treated with SBRT for tumors close to main, lobar, or segmental bronchi were selected. The association between incidence of atelectasis and bronchial dose parameters (maximum point-dose and minimum dose to the high-dose bronchial volume [ranging from 0.1 cm 3 up to 2.0 cm 3 ]) was statistically evaluated with survival analysis models. Results: Prescribed doses varied between 4 and 20 Gy per fraction in 2-5 fractions. Eighteen patients (24.3%) developed atelectasis considered to be radiation-induced. Statistical analysis showed a significant correlation between the incidence of radiation-induced atelectasis and minimum dose to the high-dose bronchial volumes, of which 0.1 cm 3 (D 0.1cm3 ) was used for further analysis. The median value of D 0.1cm3 (α/β = 3 Gy) was EQD 2,LQ = 147 Gy 3 (range, 20-293 Gy 3 ). For patients who developed atelectasis the median value was EQD 2,LQ = 210 Gy 3 , and for patients who did not develop atelectasis, EQD 2,LQ = 105 Gy 3 . Median time from treatment to development of atelectasis was 8.0 months (range, 1.1-30.1 months). Conclusion: In this retrospective study a significant dose–response relationship between the incidence of atelectasis and the dose to the high-dose volume of the bronchi is shown

  17. 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.

    The absorption of 212 Pb ions from bronchial epithelium to blood has been investigated in anaesthetized rabbits. The 212 Pb ions were introduced by intubation either into the trachea or into smaller, more distal bronchi. Removal from lung was followed by external γ-counting. Mucociliary clearance to the GI tract was blocked by tracheostomy. Two distinct phases of clearance from bronchial epithelium to blood were observed. Approximately 20% of deposited 212 Pb was rapidly absorbed with a half-time of about 4 min, the remainder with a biological half-time of about 9 h, irrespective of the site of instillation in the bronchial tree. Two hours after deposition, the 212 Pb remaining in lung was found to be partitioned between mucus and the bronchial epithelium, with a substantial but minor fraction in the epithelium. Uptake of 212 Pb in the skeleton was estimated to be about 20% of the 212 Pb entering the blood circulation. Removal by the kidneys, at 25%, was comparable with skeletal uptake. These results are compared with previously published work using rodents, dogs and man which demonstrated either rapid or slow absorption but not both phases occurring together. (author)

    Full Text Available OBJECTIVE To assess the increased diagnostic yield for pulmonary tuberculosis using bronchial washing cultures compared with sputum cultures. 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.

    Bronchial asthma is a heterogeneous disease that includes various subtypes. They may share similar clinical characteristics, but probably have different pathological mechanisms. To identify phenotypes using cluster analysis in moderate to severe bronchial asthma and to compare differences in clinical, physiological, immunological and inflammatory data between the clusters. Forty adult patients with moderate to severe bronchial asthma out of exacerbation were included. All underwent clinical assessment, anthropometric measurements, skin prick testing, standard spirometry and measurement fraction of exhaled nitric oxide. Blood eosinophilic count, serum total IgE and periostin levels were determined. Two-step cluster approach, hierarchical clustering method and k-mean analysis were used for identification of the clusters. We have identified four clusters. Cluster 1 (n=14) - late-onset, non-atopic asthma with impaired lung function, Cluster 2 (n=13) - late-onset, atopic asthma, Cluster 3 (n=6) - late-onset, aspirin sensitivity, eosinophilic asthma, and Cluster 4 (n=7) - early-onset, atopic asthma. Our study is the first in Bulgaria in which cluster analysis is applied to asthmatic patients. We identified four clusters. The variables with greatest force for differentiation in our study were: age of asthma onset, duration of diseases, atopy, smoking, blood eosinophils, nonsteroidal anti-inflammatory drugs hypersensitivity, baseline FEV1/FVC and symptoms severity. Our results support the concept of heterogeneity of bronchial asthma and demonstrate that cluster analysis can be an useful tool for phenotyping of disease and personalized approach to the treatment of patients.

    We created a system that allows the visualization of breath sounds (visual stethoscope). We compared the visual stethoscope technique with auscultation for the detection of bronchial intubation in pediatric patients. In the auscultation group, an anesthesiologist advanced the tracheal tube, while another anesthesiologist auscultated bilateral breath sounds to detect the change and/or disappearance of unilateral breath sounds. In the visualization group, the stethoscope was used to detect changes in breath sounds and/or disappearance of unilateral breath sounds. The distance from the edge of the mouth to the carina was measured using a fiberoptic bronchoscope. Forty pediatric patients were enrolled in the study. At the point at which irregular breath sounds were auscultated, the tracheal tube was located at 0.5 ± 0.8 cm on the bronchial side from the carina. When a detectable change of shape of the visualized breath sound was observed, the tracheal tube was located 0.1 ± 1.2 cm on the bronchial side (not significant). At the point at which unilateral breath sounds were auscultated or a unilateral shape of the visualized breath sound was observed, the tracheal tube was 1.5 ± 0.8 or 1.2 ± 1.0 cm on the bronchial side, respectively (not significant). The visual stethoscope allowed to display the left and the right lung sound simultaneously and detected changes of breath sounds and unilateral breath sound as a tracheal tube was advanced. © 2012 Blackwell Publishing Ltd.

    Objective: To investigate the differential diagnostic values of CT bronchial sign for peripheral solitary pulmonary lesions (SPLs). Methods: One hundred and eleven patients with peripheral SPLs were scanned using multi-slice helical CT (MSCT), and multiplanar reconstruction was performed to show the relationship between the lesion and bronchus, the differences between the benign and malignancy were compared by using chi-square test. Results: Bronchial cutoff rate in malignant lesions (47/95, 49.5%) was markedly higher than that in benign lesions (10/42,23.8%. χ 2 =7.896, P 2 =6.975,4.818, P 2 =7.390,P 2 =0.641,0.062, P>0.05). The focal bronchial wall thickening in malignancy (21/22) was markedly higher than benign lesions (1/22. χ 2 =4.185, P 2 =8.650, P<0.05). Conclusion: CT bronchial sign is very important in the differentiation of benign and malignant pulmonary lesions. (authors)

    Authors describing the bronchial vessels agree to the fact that they are characterised by a great variability in regard to their number and the place where they leave aorta (1, 2, 6). The characteristic feature of the right bronchial artery is that it often forms common trunks with other vessels (mainly with the first right aortic intercostal branch or with one of the upper oesophageal arteries). It can also have a common let-out trunk with the left upper bronchial artery (4). Bearing in mind that the operations on trachea and bronchi are difficult, and that it is very important to maintain the blood supply of the walls in the operated organs we have decided to publish our observations. They refer to a case, not described before, in which the right bronchial artery left the aortic arch in a high position making the vascular supply to the front lower half of the trachea and its bifurcation. Then, it went down to the membranous part of the right bronchus.

    Full Text Available Abstract Background Solitary endobronchial papillomas (SEP are rare tumors and most of them are described by case report. A misdiagnosis is common with viral related papillomas. A histopathological classification has recently permitted a major advancement in the understanding of the disease. Case Presentation We report a case of a mixed bronchial papilloma with an unusual endoscopic presentation. The literature was extensively reviewed to ascertain the unusual characteristics of the current case. A 39-year of age male was referred to our institution for the investigation of a slight hemoptysis. Routine examination was normal. A fibroscopy revealed an unusual feature of the right main bronchus. The lesion was a plane, non-bleeding, non-glistering sub-mucosal proliferation. No enhanced coloration was noticed. Biopsies revealed a mixed solitary bronchial papilloma. In situ HPV hybridization was negative. Endoscopic treatment (electrocautery was effective with no relapse. Conclusion This lesion contrasts with the data of the literature where papilloma were described as wart-like lesions or cauliflower tumors, with symptoms generally related to bronchial obstruction. We advise chest physicians to be cautious with unusually small swollen lesions of the bronchi that may reveal a solitary bronchial papilloma. Endoscopic imaging can significantly contribute to the difficult diagnosis of SEP by pulmonary physicians and endoscopists.

    Full Text Available ABSTRACT   Asthma is one of the major health problems in the world. Actual asthma symptoms can be treated and controlled, so that most patients can prevent the onset of symptoms throughout the day, to prevent a serious attack. Pharmacists play a role in pharmaceutical care that aims to find health care system needed to improve drug therapy of complex and significant value of drug-related morbidity and mortality, functions to improve pharmacotherapy outcomes and quality of life of patients with asthma. The patient's belief about health and illness and related behaviors are also very important to the effectiveness of pharmaceutical care. Objective research to study the role of pharmacists in pharmaceutical care in the treatment of outpatient asthma bronchiale. The type of study was cross-sectional. The number of respondents recruited was 22 patients. In this study data were obtained by direct interview using a form of data collection, accompanied by observations of the patients. Result research Patients involved in this study were 22. The total numbers of DRPs were 20 cases (problem-based and 23 cases (cause-based. The class of drugs causing most DRPs was beta-2 agonist. The subjective perceptions of symptoms experienced by the majority of patients with asthma were: shortness of breath (100%, wheezing sound (90%, fatigue and difficulty sleeping (85%. The cognitive aspect of illness perceived by the patients regarding identity, cause of illness and cure or control was correct, but those concerning consequences and timeline were still lacking. This study demonstrates that the role of pharmacists in pharmaceutical care in ambulatory asthma patients has a nature of direct counseling to patients and monitoring. Monitoring of patients on a regular basis and analysis of the occurrence of drug-related problems might help the patients to get effective, safe and rational treatment.   Keywords:    asthma, pharmaceutical care, drug related problems

    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.

    Lung cancer is the leading cause of cancer-related mortality worldwide. Early detection or prevention strategies are urgently needed to increase survival. Hyperplasia is the first morphologic change that occurs in the bronchial epithelium during lung cancer development, followed by squamous metaplasia, dysplasia, carcinoma in situ, and invasive tumor. The current study was designed to determine the molecular mechanisms that control bronchial epithelium hyperplasia. Using primary normal human tracheobronchial epithelial (NHTBE) cells cultured using the 3-dimensional organotypic method, we found that the epidermal growth factor receptor (EGFR) ligands EGF, transforming growth factor-alpha, and amphiregulin induced hyperplasia, as determined by cell proliferation and multilayered epithelium formation. We also found that EGF induced increased cyclin D1 expression, which plays a critical role in bronchial hyperplasia; this overexpression was mediated by activating the mitogen-activated protein kinase pathway but not the phosphoinositide 3-kinase/Akt signaling pathway. Erlotinib, an EGFR tyrosine kinase inhibitor, and U0126, a MEK inhibitor, completely inhibited EGF-induced hyperplasia. Furthermore, a promoter analysis revealed that the activator protein-1 transcription factor regulates EGF-induced cyclin D1 overexpression. Activator protein-1 depletion using siRNA targeting its c-Jun component completely abrogated EGF-induced cyclin D1 expression. In conclusion, we demonstrated that bronchial hyperplasia can be modeled in vitro using primary NHTBE cells maintained in a 3-dimensional (3-D) organotypic culture. EGFR and MEK inhibitors completely blocked EGF-induced bronchial hyperplasia, suggesting that they have a chemopreventive role. PMID:21505178

    The genetic background of bronchial asthma is complex, and it is likely that multiple genes contribute to its development both directly and through gene-gene interactions. Cytokines contribute to different aspects of asthma, as they determine the type, severity and outcomes of asthma pathogenesis. Allergic asthmatics undergoing an asthmatic attack exhibit significantly higher levels of pro-inflammatory cytokines, such as interleukins and chemokines. In recent years, cytokines and their receptors have been shown to be highly polymorphic, and this prompted us to investigate interleukin 6 promoter polymorphisms at position -174G/C (rs1800795) and at -572G/C (rs1800796) in relation to asthma in children. Interleukin 6 promoter polymorphisms were analyzed in bronchial asthma patients and healthy children using polymerase chain reaction-restriction fragment length polymorphism analysis. We observed a significant association between polymorphism at -174G/C and bronchial asthma (OR=3.4, 95% CI: 2.045-5.638, P<.001). Higher associations between polymorphism at IL-6 -174G/C and bronchial asthma were observed in atopic patients (OR=4.1, 95% CI: 2.308-7.280, P<8.10 -7 ). Interleukin 6 polymorphism is associated with bronchial asthma, particularly its atopic phenotype. Expression and secretion of interleukins in asthmatic patients may be affected by genetic polymorphisms, and could have a disease-modifying effect in the asthmatic airway and modify the therapeutic response.

    Full Text Available Objective: Among different epileptic syndrome infantile spasm is one of the most malignant forms which cause irrepairable brain damage in the child. Consequently the longer this type of epilepsy lasts the more harmful results will follow. The majority of children with infantile spasm are younger than one year age and only 5 percent of affected children are in the age group above one year. Materials & Methods: This descriptive study was done on 60 (36 male and 24 female infants 2-24 months age with clinical examination, observation, interview and questionnaire  in pediatric neurology department of Mofid children hospital during two years. Results: From 60 patients (36 male and 24 female, 48 case (80% symptomatic and 12 case (20% cryptogenic and idiopathic. Based on clinical manifestation 35 case (58% were flexor type. 6 case (10% extensor and 19 cases (32% mixed. In EEG hypsarrhythmia in all patients was seen. Brain CT scan in 11 cases showed brain atrophy and in remainder was normal. Conclusion: In our study etiologically symptomatic and clinically flexor type was more common. Hysparrhythmia in all patients was seen and brain CT scan in 80% of patients was normal.

    Massive hemoptysis is a life-threatening condition, and the major source of bleeding in this condition is the bronchial circulation. Bronchial artery embolization is a safe and effective treatment for controlling hemoptysis. However, the sites of origin of the bronchial arteries (BAs) have numerous anatomical variations, which can result in a technical challenge to identify a bleeding artery. We present a rare case of a left inferior BA that originated from the left gastric artery in a patient with recurrent massive hemoptysis caused by bronchiectasis. The aberrant BA was embolized, and hemoptysis has been controlled for 8 months

    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

    We systematically examined by immune histology the lungs of some widely used mouse models of asthma. These models include sensitization by multiple intraperitoneal injections of soluble ovalbumin (OVA) or of OVA with alum, followed by three intranasal or aerosol challenges 3 days apart. Within 24 h after a single challenge there is fibrinoid necrosis of arterial walls with deposition of immunoglobulin (Ig) and OVA and infiltration of eosinophilic polymorphonuclear cells that lasts for about 3 days followed by peribronchial B-cell infiltration and slight reversible goblet cell hypertrophy (GCHT). After two challenges, severe eosinophilic vasculitis is present at 6 h, increases by 72 h, and then declines; B-cell proliferation and significant GCHT and hyperplasia (GCHTH) and bronchial smooth muscle hypertrophy recur more prominently. After three challenges, there is significantly increased induced bronchus-associated lymphoid tissue (iBALT) formation, GCHTH, and smooth muscle hypertrophy. Elevated levels of Th2 cytokines, IL-4, IL-5, and IL-13, are present in bronchial lavage fluids. Sensitized mice have precipitating antibody and positive Arthus skin reactions but also develop significant levels of IgE antibody to OVA but only 1 week after challenge. We conclude that the asthma like lung lesions induced in these models is preceded by immune complex-mediated eosinophilic vasculitis and iBALT formation. There are elevations of Th2 cytokines that most likely produce bronchial lesions that resemble human asthma. However, it is unlikely that mast cell-activated atopic mechanisms are responsible as we found only a few presumed mast cells by toluidine blue and metachromatic staining limited to the most proximal part of the main stem bronchus, and none in the remaining main stem bronchus or in the lung periphery.

    Bronchoscopy is generally a safe procedure, but the induction of anaesthesia can induce bronchospasm. Consequently we investigated the influence of propofol, remifentanil and lidocaine on the tone of the human bronchial smooth muscle. The influence of propofol, remifentanil and lidocaine on the contractile response of human bronchial smooth muscle to electrical field stimulation (EFS) has been evaluated. The role of capsaicin-sensitive sensory nerves and of inducible nitric oxide synthase has also been assessed. Furthermore, the interaction between these three dugs has been measured by Bliss Independence (BI) theory. Statistical significance (P < 0.05) was assessed by Student's t test or ANOVA. Propofol (1.3 μg ml(-1)) and lidocaine (1 mg ml(-1)) reduced the baseline tone of bronchial rings (-14.45 ± 4.53% and -33.40 ± 1.07%, respectively, P < 0.05), whereas remifentanil had not such effect. Aminoguanidine prevented the relaxant effect of propofol. Propofol did not alter the bronchial contractile response to EFS following 30 min of treatment, whereas remifentanil enhanced the bronchial tension (133.83 ± 9.38%, control 101.93 ± 6.82%, P < 0.05 P < 0.05) and lidocaine completely abolished the contractility at 1 mg ml(-1) (P < 0.05). The desensitization of capsaicin-sensitive sensory nerves normalized the hyperresponsiveness induced by remifentanil (-26.77 ± 1.68%, P < 0.05). Significant BI antagonism (P < 0.001) was detected for propofol and lidocaine on the bronchial hyperresponsiveness induced by remifentanil. Propofol and remifentanil may be used safely for bronchoscopy, although remifentanil should be associated with propofol or lidocaine to prevent the potential opioid-mediated bronchospasm.

    2016-04-01

    Conclusion: Vitamin D deficiency was highly prevalent in COPD and bronchial asthma (100% and 50% respectively. Low levels of vitamin D were associated with low FEV1%, frequent exacerbations in patients with COPD and bronchial asthma, and increased COPD severity as assessed by GOLD guidelines. Important statistically significant negative associations between vitamin D level and both asthma control and asthma severity according to GINA classification were also found. Thus it is advised to include vitamin D levels in the routine assessment of patients with bronchial asthma and COPD, as well as studying the importance and clinical impact of oral supplementation of vitamin D in patients with COPD and bronchial asthma should be an important goal of future research.

    Objective: To investigate the clinical significance of changes of serum TNF, IL-8 and GM-CSF in pediatric patients with bronchial asthma. Methods: Serum TNF, IL-8 and GM-CSF levels were measured with RIA in 32 pediatric patients with bronchial asthma and 30 controls. Results: Serum levels of TNF, IL-8 and GM-CSF were very significantly higher in pediatric patients with bronchial asthma than those in controls (P<0.01). After one week treatment, the levels dropped considerably but still remained significantly higher than those in controls (P<0.05). Conclusion: These cytokines participated in the pathogenesis of bronchial asthma. Monitoring the changes of their serum levels was helpful for the management of the diseases. (authors)

    The authors studied regional pulmonary function after treatment with bronchial plastic surgery for bronchial lesion from bronchial tuberculosis and with irradiation for bronchial lesion from carcinoma using positron emission tomography and Tc-MAA. Six patients with bronchial tuberculosis and 6 with bronchogenic carcinoma were examined. Two of the 6 bronchial tuberculosis patients were examined before and after surgery. In all 6 patients with bronchial tuberculosis, ventilation and alveolar volume were recovered with improvement of bronchial lesion. In 2 patients examined before and after surgery, lung function of the normal disease-free side became worse after surgery. This phenomenon was explained by the fact that the compensated pulmonary function of contra lateral lung due to decreased function of the diseased side returned to normal function with improvement of the diseased lung. On the other hand, the regional pulmonary function did not improve in 2 patients with main bronchial lesion from bronchogenic carcinoma, even if atelectasis of the diseased lung was improved by irradiation. However, the regional pulmonary function was improved with the recovery of bronchial obstruction in lobar atelectasis by carcinoma. The difference of the results depended on whether pulmonary blood flow disturbance existed or not. If pulmonary blood flow disturbance was severe, ventilatory function was not recovered due to the mechanism of maintaining the ventilation-perfusion equilibrium. (author)

    Objectives The shape of the flow-volume (F-V) curve is known to change to showing a prominent plateau as stenosis progresses in patients with tracheal stenosis. However, no study has evaluated changes in the F-V curve according to the degree of bronchial stenosis in patients with unilateral main bronchial stenosis. Methods We performed an analysis of F-V curves in 29 patients with unilateral bronchial stenosis with the aid of a graphic digitizer between January 2005 and December 2011. Results The primary diseases causing unilateral main bronchial stenosis were endobronchial tuberculosis (86%), followed by benign bronchial tumor (10%), and carcinoid (3%). All unilateral main bronchial stenoses were classified into one of five grades (I, ≤25%; II, 26%-50%; III, 51%-75%; IV, 76%-90%; V, >90% to near-complete obstruction without ipsilateral lung collapse). A monophasic F-V curve was observed in patients with grade I stenosis and biphasic curves were observed for grade II-IV stenosis. Both monophasic (81%) and biphasic shapes (18%) were observed in grade V stenosis. After standardization of the biphasic shape of the F-V curve, the breakpoints of the biphasic curve moved in the direction of high volume (x-axis) and low flow (y-axis) according to the progression of stenosis. Conclusion In unilateral bronchial stenosis, a biphasic F-V curve appeared when bronchial stenosis was >25% and disappeared when obstruction was near complete. In addition, the breakpoint moved in the direction of high volume and low flow with the progression of stenosis. PMID:26045916

    Full Text Available Due to tight functional interrelation between respiratory apparatus and blood circulation, exacerbation of bronchial asthma in children is associated with changes of cardiovascular system. Multifacetedness of this problem determines comprehensive approach to examination of children with bronchial asthma, involving most available methods of heart function evaluation: echocardiographic heart study with Doppler sonography and electrocardiography. Of great importance is investigation of systemic and pulmonary hemodynamics and microcirculation in bronchial asthma depending on its clinical course. It was found that children with exacerbation of bronchial asthma were detected with pulmonary hypertension, which had gradual regression after attack alleviation. During the remission stage, hemodynamics disturbances in lesser circulation were present in long-lasting and severe course of disease. However, the increase in the pulmonary blood flow parameters in patients only in the early period after attack can be regarded as a compensatory response from the lesser circulation to the decline in respiratory function indices. Therefore, despite the great achievements of science in the study of pathophysiological mechanisms and clinical features of bronchial asthma at different ages, it is necessary to continue further study of all aspects of bronchial asthma in children, because it is not as well studied as asthma in adults.

    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.

    Full Text Available The modern approach to the therapy of bronchial asthma among children includes wide application of the inhalant glucocorticosteroids. The application of the spray-based medicines provides for fast admission into the respiratory passages, high local activity, low risk of the systemic side effects. The choice of a specific medicine depends both on the patient’s ability to effectively and correctly use the prescribed medication and a medicine itself. The highest number of hospitalizations and cases of seeking medical emergency advice is recorded among children aged under 4. The only inhalant glucocorticosteroids approved for application among children under 4 is budesonide in a suspension for inhalations.Key words: bronchial asthma, medical emergency advice, inhalant glucocorticosteroids, children.

    Acute bronchial mucosal sloughing related to Toxic Epidermal Necrolysis (Lyell syndrome) is widely reported in literature. On the contrary severe respiratory involvement is rare in post-infectious or toxic Epitheliolysis (Stevens-Johnson syndrome). There is no well-known predictive sign of bronchial epithelium involvement. An 18-year-old patient was admitted for Stevens-Johnson syndrome related to sulfasalazine (salazosulfapyridine). There were no respiratory signs. An acute respiratory failure occurred 36 hours after from admission due to an obstructive and desquamative necrosis of the tracheobronchial epithelium. We purpose that a fiberoptic laryngoscopy should be performed even in non-dyspneic patients suffering from Stevens-Johnson syndrome if hypersecretion is present. Fiberoptic bronchoscopy can be helpful in these cases.

    Results. We have examined 80 children aged from 6 months to 3 years with acute obstructive bronchitis, and 40 age-matched children with acute nonobstructive bronchitis. The factors of high risk were determined and the mathematical model for predicting bronchial obstruction in acute bronchitis was created. Father’s age over 38 years, intrauterine growth restriction, maladjustment syndrome, early artificial feeding, genetic predisposition to atopy, passive smoking, fever in the postvaccination period, history of acute obstructive bronchitis and number of its episodes more than 2, paratrophia became prognostically significant. Fever up to 37.7 °C, mild intoxication syndrome up to 3 days, slow nasal breathing, IL-13 within 4.05–6.71 pg/ml and the relative number of lymphocytes expressing NF-kB less than 49.8 % were also associated with the development of bronchial obstruction in acute bronchitis.

    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.

    This work consists of a retrospective definition of disease courses of 859 patients with lung tumors and the definition of the survival curves in their dependence on histology, radiation dose and sex. With 721 larger-celled bronchial carcinomas the ratio of men to women was 12:1. The age peak lay between 60 and 70 years. The one/five year survival rate of all included larger-celled bronchial carcinomas (n=701) was, independent from the therapy form, 35.7, resp. 4.78%. The one year/five year survival rates were for the squamous epithelia 31.08/0.58%, for the undifferentiated carcinomas 25.34/3.41%, and for the lung tumors without histology 35.4/5.14%. Lobectomized patients with squamous epithelium carcinoma had in comparison to pneumonectomized patients a clearly higher survival chance. A clearly sex-dependent predisposition for a certain type of carcinoma was not present. (TRV) [de

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

    The management of the patient with pulmonary hypertension is a challenge for the anesthesiologists because the risk of right-sided heart failure is markedly increased. We experienced a case of general anesthesia for a patient with pulmonary hypertension (mean pulmonary arterial pressure 39 mmHg), bronchial asthma and obesity. A 31-year-old woman was scheduled for arytenoid rotation for left recurrent nerve palsy. We applied routine monitors (noninvasive blood-pressure, five-lead electrocardiogram, pulse oximeter), and direct blood pressure monitoring through the radial artery. Anesthesia was induced with midazolam 4 mg, fentanyl 100 microg and sevoflurane 5%, and maintained with sevoflurane (1-2%) and nitrous oxide in oxygen. Surgery was completed in 100 minutes without any complications. We could successfully perform general anesthesia in a patient complicated by pulmonary hypertension, bronchial asthma and obesity, without invasive right-sided heart catheterization.

    The kinetics of bronchial epithelium cells was investigated in 14- to 20-days old rats of an inbred strain (Wistar-WU, Mueller/Haan). In agreement with the data of the relevant literature, light microscopy revealed a successive evolution of the bronchial tree which consists of a glandular, a canalicular, and an alveolar part. Prophases, metaphases and reconstruction phases are relatively long mitotic phases, while anaphases and telophases are relatively short ones. Combined nuclear volumetry and autoradiography showed that the G-1 phase nuclei are smaller than the 3 H-labelled nuclei at the onset of the S phase and these, in turn, are smaller than the nuclei at the end of the S phase with double 14 C- or 3 H-label or with 'strong' 3H label.

    A 37-year-old patient presented with a self-limiting episode of moderate haemoptysis. Contrast-enhanced chest computed tomography showed a tortuous and dilated right bronchial artery arising from the descending aorta at the level of T6. Therapeutic angiography was attempted, but in the presence of spinal artery arising from the bronchial artery in question, selective embolization was contraindicated due to risk of spinal cord ischaemia. After a multidisciplinary meeting, it was decided to attempt surgery to ligate this pathological artery. We performed minimally invasive robot-assisted ligation of this pathological artery. The postoperative course was uneventful with good clinical and radiological outcome at 3-month follow-up. A minimally invasive approach provides a real alternative to embolization and could be a therapeutic option.

    Bronchial atresia is a rare congenital abnormality that usually shows a juxta-hilar mass with distal radiolucency on conventional x-ray films. Most patients are young and have no symptoms. Computed tomography usually confirms the diagnosis, allowing conservative management of the asymptomatic cases. The authors report three cases of bronchial obstruction. One of the patients was of particular importance and interest, a 45-year-old female patient with symptoms of respiratory infection, due to the association with a bulky bronchocele. The diagnosis was made by analyzing the findings of conventional x-ray films and computed tomography, and the comparison with previous conventional x-ray films and linear tomography, which had already demonstrated abnormalities. A literature review on the clinical and radiological findings of this pulmonary malformation is presented. (author)

    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.

    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. PMID:23459001

    Objective: To probe into the angiographic signs and the variations of bronchial arteries for pulmonary tuberculosis or bronchiectasis with massive hemoptysis. Methods: 25 patients with pulmonary tuberculosis and 15 patients suffered from bronchiectasis accompanied by massive hemoptysis were undertaken bronchial arterial embolization (BAE). All patients were embolized with gelfoam including 32 with spring coils in addition. Results: 63 arteries demonstrated angiographic signs of hemoptysis in 40 patients. The immediate stanching rate was 92.5%(37/40). The bronchopulmonary shunt formation sign shown by angiograph was the major feature of tuberculosis (P=0.0528) and the enlarged tortuous arteries in bronchiectasis were more to be demonstrated than in tuberculosis (P<0.05). Conclusions: The BAE for patients with tuberculosis ought to be performed in the smaller arteries. BAE for patients with bronchiectasis should to be taken in the trunk of arteries. (authors)

    Pulmonary parenchymal endometriosis is extremely rare and usually manifests itself with a recurrent hemoptysis associated with the menstrual cycle. The therapies proposed for women with endometriosis consist of medical treatments and surgery. Bronchial artery embolization has become a well-established and minimally invasive treatment modality for hemoptysis, and to the best of our knowledge, it has not been reported in pulmonary endometriosis. We report a case of pulmonary parenchymal endometriosis treated with embolotheraphy for hemoptysis.

    The high incidence of pneumopathy in intensive care units might be due to the pulmonary aspiration of gastric juice following gastro-oesophageal reflux. The paper describes a radio-isotopic method using material easy to install at the patient's bedside. This technique demonstrated aspiration of gastric juice in the lungs of 8 of 25 intensive care patients investigated. Such a method might be useful later to demonstrate that silent bronchial aspirations of gastric juice are responsible for pulmonary complications.

    There have been several investigations suggesting an involvement of activated neutrophils in the development of grain dust (GD)-induced occupational asthma. Interleukin-8 in the sputa from GD-induced asthmatic patients increased significantly after the exposure to GD. To confirm IL-8 production from bronchial epithelial cells when exposed to GD, and to evaluate the role of IL-8 on neutrophil recruitment. We cultured Beas-2B, a bronchial epithelial cell line. To observe GD-induced responses, four different concentrations ranging from 1 to 200 microg/mL of GD were incubated for 24 hours and compared with those without incubation of GD. To evaluate the effect of pro-inflammatory cytokines on IL-8 production and neutrophil chemotaxis, epithelial cells were incubated with peripheral blood mononuclear cell (PBMC) culture supernatant derived from subjects with GD-induced asthma exposed to 10 microg/mL of GD, and then compared with those without addition of PBMC supernatant. The level of released IL-8 in the supernatant was measured by enzyme-linked immunosorbent assay. Neutrophil chemotactic activity of the culture supernatant was determined by modified Boyden chamber method. Interleukin-8 production and neutrophil chemotactic activity from bronchial epithelial cells significantly increased with additions of GD in a dose-dependent manner (P < .05, respectively), and were significantly augmented with additions of PBMC supernatant (P < .05, respectively) at each concentration. Close correlation was noted between neutrophil chemotactic activity and IL-8 level (r = 0.87, P < .05). Compared with the untreated sample, pre-treatment of anti-IL-8 antibody induced a significant suppression (up to 67.2%) of neutrophil chemotactic activity in a dose-dependent manner. These results suggest that IL-8 produced from bronchial epithelial cells may be a major cytokine, which induces neutrophil migration into the airways when exposed to GD.

    Roentgenopneumopolygraphy (RPPG) was used to examine 48 patients with bronchial asthma and all patients showed a reduction of one or several indices of zonal ventilation and / or biomechanics of the respiratory act. Inhalation of bronchoiytics improved all indices of RPPG. But most patients revealed local disorders of ventilation resistant to the effect of broncholytic agents. Local therapy of the corresponding lung regions produced a positive effect

    We used the powered vascular staple (PVS) instead of the conventional staple technique [the utilization of the powered linier cutter (PLC)] or ligation for total 23 segmental or subsegmental bronchi with less than 10 mm in the bronchial luminal size on computed tomography (CT) in thoracoscopic segmentectomy. Our results suggested that the availability of the PVS represents a novel advance in the armamentarium and may have a possibility of being pervasive widely however, more observative periods and further sample accumulation are needed.

    Studies in cystic fibrosis (CF) generally focus on inflammation present in the airway lumen. Little is known about inflammation occurring in the airway wall, the site ultimately destroyed in end-stage disease. To test the hypothesis that inflammatory patterns in the lumen do not reflect those in the airway wall of children with CF. Bronchoalveolar lavage (BAL) fluid and endobronchial biopsies were obtained from 46 children with CF and 16 disease-free controls. BAL cell differential was assessed using May-Gruenwald-stained cytospins. Area profile counts of bronchial tissue immunopositive inflammatory cells were determined. BAL fluid from children with CF had a predominance of neutrophils compared with controls (median 810×10(3)/ml vs 1×10(3)/ml, p<0.0001). In contrast, subepithelial bronchial tissue from children with CF was characterised by a predominance of lymphocytes (median 961 vs 717 cells/mm(2), p=0.014), of which 82% were (CD3) T lymphocytes. In chest exacerbations, BAL fluid from children with CF had more inflammatory cells of all types compared with those with stable disease whereas, in biopsies, only the numbers of lymphocytes and macrophages, but not of neutrophils, were higher. A positive culture of Pseudomonas aeruginosa was associated with higher numbers of T lymphocytes in subepithelial bronchial tissue (median 1174 vs 714 cells/mm(2), p=0.029), but no changes were seen in BAL fluid. Cell counts in BAL fluid and biopsies were positively correlated with age but were unrelated to each other. The inflammatory response in the CF airway is compartmentalised. In contrast to the neutrophil-dominated inflammation present in the airway lumen, the bronchial mucosa is characterised by the recruitment and accumulation of lymphocytes.

    2012-01-15

    We report on three cases of longstanding pulmonary tuberculosis patients with coronary to bronchial artery fistula (CBF) who presented with recurrent massive hemoptysis. The first and second patients died because of decreased functional pulmonary volume plus massive hemoptysis and cannulation failure of CBF due to hypovolemic vasospasm, respectively. When recurrent hemoptysis occurs despite successful embolization treatment, CBF should be considered as a potential bleeding source. Moreover, a coronary angiography should be performed, especially in patients with longstanding cardiopulmonary disease such as pulmonary tuberculosis.

    Intra-arterial digital subtraction angiography (IADSA) has been used with advantage for control of the results of bronchial artery infusion of drugs for primarily unresectable bronchogenic carcinoma. The IADSA has been performed as road mapping prior to therapy. Drug treatment has been performed with 4 different regimes, depending on tumour type. Debulking and in some cases complete healing are the results, which are superior to other reported treatments. (author). 7 refs.; 4 figs.; 3 tabs

    Transfer of 50 million rabbit allogeneic lymphocytes from either bronchus-associated lymphoid tissue (BALT) or Peyer's patches into 1000 R x-irradiated recipients results, 6 days later, in predominant repopulation of gut and bronchial lamina propria, as well as spleen, with IgA-containing cells. After repopulation with BALT or Peyer's patch cells, lymphoid follicles in both gut and lung showed peripheral cellular membrane type of fluorescence with fluorescein-conjugated anti-IgA antisera only. Six days after x-irradiation alone, little evidence of repopulation was seen and immunofluorescent qualitative observations of gut and lung, and quantitative data in the spleen, confirmed these findings. After transfer of 50 million lymph node cells, very few immunoglobulin-containing cells were seen in the gut or bronchial lamina propria. These results suggest that there may be a common mucosal immunologic system, and that repopulation of gut and lung lamina propria may be through the organized lymphoid tissue therein. (U.S.)

    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.

    Full Text Available The aim of research is to study the state of circadian arterial tension profile in the patients with bronchial asthma and hypertensive disease as comorbid disease. Materials and methods. The research has been performed at 76 patients with bronchial asthma and hypertensive disease as comorbid disease (the main group and 52 patients with hypertensive disease as the comparison group. The groups were comparable with respect to the gender and age sign. Investigation was performed in the period of clinical remission. The main method used in this research was the investigation of day arterial tension profile in the time of its monitoring. Results. It has been revealed the presence of frequent and expressed change from the side of the studied indexes, especially in the patients with comorbid pathology, which were characterized by more frequent and more significant disorders from the side of diastolic blood pressure, especially at night in combination with more considerable and more rapid rise in early morning hours. The day arterial tension profile was characterized either with insufficient decline of arterial pressure at night or, opposite, with its sharp decrease. Specified disorders were increased as far as heaving of main and comorbid diseases, presence of disorders from the side of lipid exchange were not related to the phase of bronchial asthma (remission, exacerbation and level of its flow control.

    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 cancerizationclose 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 normalclose quotes bronchial epithelial cells

    To address the limitations of silicone stents, we designed a hinged self-expandable covered metallic stent. The aim of this study was to evaluate the safety and efficacy of the customized stents in clinical applications. This was a retrospective analysis. Under conscious sedation and local anesthesia, the stents were implanted or removed by interventional radiologists, with fluoroscopic guidance. Of 24 patients with benign main bronchial stenosis, stents were successfully placed in 21 (87.5%). The low-pressure balloon before dilation failed in 1 case (4.17%) of left main bronchial cicatricial stenosis. In 2 other cases (8.33%), stent placement was abandoned. Stents were successfully removed between 29 and 103 days after the procedure. After stent removal, the follow-up lasted for at least 12 months. Restenosis occurred only in 1 case (4.55%) owing to bronchial collapse 3 days after stent removal. Dyspnea occurred in another case (4.55%) at 2 months after retrieval; recurrence was confirmed using bronchoscopy, leading to a left pneumonectomy. The described procedure is safe and easy to be performed and avoids the use of intubation, bronchoscopy, and general anesthesia. Copyright © 2017 The Society of Thoracic Surgeons.

    Objective: Massive hemoptysis is always a life-threatening respiratory disease and requires emergency management. This study is to evaluate the clinical efficacy and safety of bronchial artery embolization (BAE) by using permanent particles in the management of massive hemoptysis. Methods: Thirty-three patients with massive hemoptysis who had failed to respond to medical management received BAE. The causative diseases included bronchiectasis (n = 24), bronchogenic carcinoma (n = 4), bronchiectasis complicated with tuberculosis (n = 2), bronchial disease (n = 2) and traumatic destroyed lung (n = 1). Embolization with sodium alginate microspheres (KMG) was performed in all patients, and additional use of microcoils was carried out in patients complicated with bronchial-pulmonary fistulae. All patients were followed up for at least 3 months. Results: BAE was successfully accomplished in all patients. The cessation of hemoptysis was immediately obtained in all patients, with a success rate of 100%. Recurrence of hemoptysis within one month after BAE was seen in 3 patients (9.1%, 3/33). No serious complications occurred and the mean postoperative hospitalization days of the patients were 10 days. Conclusion: With satisfactory instant clinical results, BAE by using permanent particles is a safe, effective treatment for the massive hemoptysis. (authors)

    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.

    We have previously shown that gene expression alterations in normal-appearing bronchial epithelial cells can serve as a lung cancer detection biomarker in smokers. Given that miRNAs regulate airway gene expression responses to smoking, we evaluated whether miRNA expression is also altered in the bronchial epithelium of smokers with lung cancer. Using epithelial brushings from the mainstem bronchus of patients undergoing bronchoscopy for suspected lung cancer (as part of the AEGIS-1/2 clinical trials), we profiled miRNA expression via small-RNA sequencing from 347 current and former smokers for which gene expression data were also available. Patients were followed for one year postbronchoscopy until a final diagnosis of lung cancer ( n = 194) or benign disease ( n = 153) was made. Following removal of 6 low-quality samples, we used 138 patients (AEGIS-1) as a discovery set to identify four miRNAs (miR-146a-5p, miR-324-5p, miR-223-3p, and miR-223-5p) that were downregulated in the bronchial airway of lung cancer patients (ANOVA P cancer patients (GSEA FDR lung cancer significantly improves its performance (AUC) in the 203 samples (AEGIS-1/2) serving an independent test set (DeLong P lung cancer, and that they may regulate cancer-associated gene expression differences.

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.

    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.

    We have investigated the role of human bronchial cyclic nucleotide phosphodiesterases in the effects of fenspiride, a drug endowed with bronchodilator and anti-inflammatory properties. Functional studies on human isolated bronchi showed that fenspiride (10(-6)-3 x 10(-3) M, 30 min) induced a shift to the left of the concentration-response curves for isoprenaline and sodium nitroprusside with -logEC50 values of 4.1+/-0.1 (n = 7) and 3.5+/-0.2 (n = 8), respectively. Biochemical studies were carried out on three human bronchi in which separation of cyclic nucleotide phosphodiesterase isoenzymes was performed by ion exchange chromatography followed by determination of phosphodiesterase activity with a radioisotopic method. Phosphodiesterase 4 (cyclic AMP-specific) and phosphodiesterase 5 (cyclic GMP-specific) were the major phosphodiesterase isoforms present in the human bronchial tissue. The presence of phosphodiesterase 1 (Ca2+/calmodulin-stimulated), phosphodiesterase 2 (cyclic GMP-stimulated) and, in two cases, phosphodiesterase 3 (cyclic GMP-inhibited) was also identified. Fenspiride inhibited phosphodiesterase 4 and phosphodiesterase 3 activities with -logIC50 values of 4.16+/-0.09 and 3.44+/-0.12, respectively. Phosphodiesterase 5 activity was also inhibited with a -logIC50 value of approximately 3.8. Fenspiride (fenspiride is an effective inhibitor of both cyclic AMP and cyclic GMP hydrolytic activity in human bronchial tissues and this action may contribute to its airway effects.

    There have been few reports suggesting involvement of neutrophils in induction of bronchoconstriction after inhalation of grain dust. To understand the role of neutrophils in pathogenesis of grain dust-induced asthma. We observed serum neutrophil chemotactic activity during grain dust-bronchoprovocation tests in six asthmatic subjects with positive bronchial challenges (group I). They were compared with those of six symptomatic subjects from the same workplace with negative bronchial challenges (group II). After grain dust inhalation, serum neutrophil chemotactic activity significantly increased at 30 minutes (P = .028), and then decreased to baseline level at 240 minutes (P = .028) in five subjects of group I having isolated early asthmatic responses. Enhanced neutrophil chemotactic activity was persistent for up to 240 minutes in one asthmatic subject having both early and late asthmatic responses. There was, however, no significant change in serum neutrophil chemotactic activity during bronchial challenges in subjects of group II. Pre-incubation of sera with anti-interleukin-8 (IL-8) antibody did not affect the neutrophil chemotactic activity results of group I subjects. These results suggest that enhanced neutrophil chemotactic activity distinct from IL-8 may contribute to significant bronchoconstriction induced by grain dust.

    Safe development and application of nanotechnologies in many fields require better knowledge about their potential adverse effects on human health. Evidence of abilities of nanoparticles (NPs) to cross epithelial barriers and reach secondary organs via the bloodstream led us to investigate the translocation of SiO 2 NPs of 50 nm (50 nm-SiO 2 -NPs) across human bronchial epithelial cells that are primary targets after exposure to inhaled NPs. We quantified the translocation of fluorescently labelled SiO 2 NPs at non-cytotoxic concentrations (5 and 10 μg/cm 2 ) across Calu-3 epithelial monolayer. After 14 days in culture Calu-3 cells seeded onto 3 μm-polycarbonate Transwell membranes formed an efficient bronchial barrier assessed by measurement of the transepithelial electric resistance and quantification of the permeability of the monolayer. After 24 hours of exposure, we observed a significant translocation of NPs that was more important when the initial NP concentration decreased. Confocal microscopy observations revealed NP uptake by cells and an important NP retention inside the porous membrane. In conclusion, 50 nm-SiO 2 -NPs can cross the human bronchial epithelial barrier without affecting the integrity of the epithelial cell monolayer.

    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. 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. 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 tamsulosin. 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 Tracheobronchomegaly(Mounier–Kuhn syndrome is dilatation of the trachea and major bronchi because of atrophy or absence of elastic fibers and smooth muscle cells .Patients presenting to primary care physician with lower respiratory tract symptoms like dyspnoea and wheezing are often diagnosed with COPD or asthma and started on treatment. There are uncommon conditions like Mounier-Kuhn syndrome (MKS that can present with similar symptoms and it is important for the primary care physician to keep them in mind when evaluating the patients. It is important to identify MKS, as early recognition can lead to better management and prevention of complications. Very few cases of MKS with Bronchial Asthma have been reported so far. We present a case of 65 year old male who presented with intermittent episodes of cough with productive sputum ,wheezing and breathing difficulty since last 35 years and was treated for Bronchial Asthma since last 25 years. He was later diagnosed with Mounier–Kuhn syndrome with Bronchial Asthma by clinical history supported by Radiological evidences.

    This study examines the possibility that products of neutrophils and eosinophils could increase the responsiveness of human isolated bronchial tissue. Neutrophils and eosinophils were isolated from the peripheral blood of healthy volunteers. The cells were incubated with 1 microM calcium ionophore A23187 for 10-15 min then centrifuged, the supernatant collected and stored at -70 degrees C. Human bronchial rings (2-3 mm diameter, 3-4 mm long) were prepared from specimens resected at thoracotomy. The tissues were suspended in organ baths under a 1 g load and changes in tension measured isometrically. Stable contractions to bolus doses of histamine (0.1-10 microM) or to electrical field stimulation (40-100 V, 4-16 Hz, 1 ms for 20 s) were established. Supernatant from 106 neutrophils or 105 eosinophils was then added and tissue responsiveness reassessed. Neutrophil supernatant increased tissue responsiveness to histamine and electrical field stimulation by 54 +/- 17% (n = 5, p less than 0.05) and 18 +/- 7% (n = 6, p less than 0.05), respectively. Eosinophil supernatant increased the histamine response by 60 +/- 23% (n = 8, p less than 0.05) while tissue responsiveness to electrical field stimulation was unchanged (n = 3). Thus, as neutrophils and eosinophils can change the responsiveness of human bronchus in vitro it is possible that they do this in vivo and may not simply be temporally related to the development of bronchial hyperresponsiveness.

    Purpose: We report an unusual pattern of referred pain to the ipsilateral forehead and orbit observed during bronchial artery embolization (BAE) for massive hemoptysis due to pulmonary tuberculosis (TB) and postulate possible neural mechanisms for its occurrence.Methods: Seven men, from a series of 194 patients (171 men, 23 women) undergoing BAE (right bronchial artery 4, left 3) with gelatin sponge for control of massive hemoptysis due to pulmonary TB form the subject of this report.Results: Embolization was successful in achieving control of hemoptysis in these patients and there were no complications following the embolization. Transient, moderately severe, ipsilateral supraorbital and/or retroorbital pain occurred only during the injection of the gelatin sponge contrast mixture into the bronchial artery. The pain did not occur during the injection of heparinized saline or ionic contrast medium.Conclusions: Referred pain during BAE is an unusual phenomenon. Acute vessel distension triggering visceral sensations is probably the causative mechanism. Sympathetic afferents from the bronchi coursing through the posterior pulmonary plexus eventually pass to the trigeminal ganglion via the carotid sympathetic chain. The ophthalmic and maxillary divisions of the trigeminal nerve then mediate pain sensation to the ipsilateral forehead and orbit. Similarly, parasympathetic afferents from the pulmonary plexus crossing the nucleus of the spinal tract of the trigeminal nerve may be responsible for interexchange of impulses to the neurons in this nucleus. Sensory fibers of the ophthalmic and maxillary nerves relaying in this nucleus are then involved in this pain being referred to the forehead and orbit.

    Norrie disease (ND) is a rare X-linked recessive disorder characterized by congenital blindness and in some cases, mental retardation and deafness. Other neurological complications, particularly epilepsy, are rare. We report on a novel mutation identified in a patient with ND and profound mental retardation. The patient was diagnosed at the age of 6 months due to congenital blindness. At the age of 8 months he developed infantile spasms, which were diagnosed at 11 months as his EEG demonstrated hypsarrhythmia. Mutation analysis of the ND gene (NDP) of the affected child and his mother revealed a novel missense mutation at position c.134T > A resulting in amino acid change at codon V45E. To the best of our knowledge, such severe neurological involvement has not been previously reported in ND patients. The severity of the phenotype may suggest the functional importance of this site of the NDP gene.

    Objective Vasospasm is the primary obstacle to widespread adoption of the radial artery as a conduit in coronary artery bypass grafting. We used optical coherence tomography, a catheter-based intravascular imaging modality, to measure the degree of radial artery spasm induced by means of harvest with electrocautery or a harmonic scalpel in patients undergoing coronary artery bypass grafting. Methods Radial arteries were harvested from 44 consecutive patients with a harmonic scalpel (n = 15) or electrocautery (n = 29). Vessels were imaged before harvesting and after removal from the arm, with saphenous vein tracts serving as internal controls. Optical coherence tomographic findings for the degree of harvesting-induced injury were validated against histologic measures. Results Optical coherence tomographic measures of endovascular dimensions and injury correlated strongly with histologic findings. Mean luminal volume, a measure of vasospasm, decreased significantly less after harvesting with a harmonic scalpel (9% ± 7%) than with electrocautery (35% ± 6%, P = .015). Completely intact intima was present in 11 (73%) of 15 radial arteries harvested with a harmonic scalpel (73%) compared with 9 of 29 arteries harvested by means of electrocautery (31%, P = .011). Intraoperative flow measurements and patency rates at 5 days postoperatively were not significantly different among groups. Conclusions Optical coherence tomography provides a level of speed and accuracy for quantifying endothelial injury and vasospasm that has not been described for any other modality, suggesting potential as an intraoperative quality assurance tool. Our optical coherence tomographic findings suggest that the harmonic scalpel induces less spasm and intimal injury compared with electrocautery. PMID:19026820

    Full Text Available The need to develop an integrated approach to the treatment of children with bronchial asthma is conditioned by a significant increase in morbidity, emergence of more severe forms of the disease and a lack of radical treatment methods. Along with the development and implementation of modern drug treatment methods, the most topical issues are a consideration of the socio-psychological characteristics of patients and psychological and pedagogical support of children during treatment. Study Objective: To study the lifestyle peculiarities of primary schoolchildren (7–10 years with bronchial asthma and their psychological state. Patients and Methods. The study included children with bronchial asthma (atopic form, partially controlled course as well as conditionally healthy peers (health groups I and II as a comparison group. The psychological status of the observed was assessed using Dembo-Rubinstein self-evaluation method, modified «Human Figure» method, and Varga-Stolin parental relationship test. Results. The study involved 75 children (mean age 8.2 ± 0.6 years, including girls 59%, illness duration 3.2 ± 0.5 years and their parents (mothers made 79% of them. The comparison group consisted of 54 conditionally healthy children (mean age 8.4 ± 0.3, girls 54% and their parents (mothers — 85%, fathers — 15%. It is shown that the lifestyle of primary schoolchildren changed due to illness distorts the process of personality development and leads to the emergence of difficulties in the emotional and personality sphere: a reduced background of mood (35; 46.6% versus 11; 20%, blockage of experiences and difficulties in their verbalization (56; 75% versus 25; 46%, defensive-aggressive type of behavior in a stress situation (68; 91% versus 25; 46%, pronounced intrapersonal conflict (47; 62% versus 32; 59%, and communication problems (unsociability, restriction in communication, social fears.

    Objective: The presence of bronchial artery to pulmonary circulation shunt (BPS) is the pathologic reason for refractory hemoptysis. Those who have accepted traditional bronchial arterial embolization (BAE) treatment usually carry high risks of recurrence of hemoptysis. At the same time,because of the limits of BAE treatment, safety can not be ignored when we pay full attention to its therapeutic effect. This research aims to find out an effective method to treat the refractory hemoptysis with BPS. Methods: During the period from Sep. 1996 to Feb. 2010, two hundred and twelve patients of hemoptysis were treated with BAE. Of the total 212 patients, BPS was confirmed by DSA angiography in 99, including 72 males and 27 females with a mean age of 47.6 years. The primary diseases included bronchiectasis (n = 25), tuberculosis (n = 64) and inflammatory disorders(n = 10). All patients were treated with BAE. According to the embolization agent used in the treatment the patients were divided into pure Gelfoam group (n = 52) and permanent embolization group (n = 47, using PVA particles, coils, etc.). All patients were followed up regularly at one day, two weeks, four weeks, six months, one year, two years after the treatment. The data were analyzed by using chi square test and rank sum test. Results: Of 52 cases in permanent embolization group, complete cure was achieved in 49, excellent results in 2 and effective response in one. For patients in pure Gelfoam group, complete cure was obtained in 37, excellent results in 16, effective response in 2 and ineffectiveness in 2. Statistic analysis showed that a significant difference in therapeutic effectiveness existed between two groups (P < 0.05). Conclusion: This study clearly indicates that selective bronchial arterial permanent dual embolization is an effective technique for the treatment of refractory hemoptysis, which is definitely superior to the pure Gelfoam emboliztion in obtaining excellent therapeutic results.

    Full Text Available Purpose: to analyze the frequency of polymorphic loci associations rs 1042713 (Arg16Gly of ADRβ2 gene in children with bronchial asthma. Patients and methods: in-depth clinical examination using the special methods of investigation, conducted to 62 children suffering from bronchial asthma. The results of investigation. As a result of depth collection of anamnesis, it was revealed that in 73.68% of patients the anamnesis was unburdened. Among the examined patients, bronchial asthma manifested at the early age in 18 children (33.96% in preschool age in 17 children (32.08%, and in a primary school in 18 children (33.96%. The early debut of disease associated with genotype Arg16Gly, while late manifestation observed in children with genotype Gly16Gly. Mostly the family inheritance depends on mother health, regardless of the severity of bronchial asthma. Іt was found that in both types of inheritance (paternal and maternal dominated genotype Arg16Gly. Found that girls often associated with asthma genotype Gly16Gly (56.52% and Arg16Gly (39.13% while the boys with genotype Arg16Gly (53.84%, less with Gly16Gly (38.89%. However, genotype Arg16Arg was observed in individual patients and in the case of intermittent disease. In case of allergen-induced and virus-induced phenotypes the genotype Arg16Gly was more often diagnosed. It was clarified that intermittent flow associated with two genotypes: Arg16Gly (47.37% and Gly16Gly (42.11%. The persistent mild course of bronchial asthma replied to genotype Gly16Gly (64.71%, but with moderate persistent — to Arg16Gly (57.69%. A good bronchodilator response was observed in patients with genotype diagnosed Arg16Gly and Gly16Gly. At the same time, patients with genotype Arg16Arg ADRβ2 needed the use of combined drugs to overcome the attack. Conclusions: Allelic polymorphism differences of ADRβ2 gene in children with asthma were diagnosed and it indicates that dependence of debut was genetically based as well

    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.

    Full Text Available Tonic spasms have been most commonly associated with multiple sclerosis. To date, few reports of series of patients with neuromyelitis optica and tonic spasms have been published. Methods: We analyzed the characteristics and frequency of tonic spasms in 19 subjects with neuromyelitis optica. Data was collected using a semi-structured questionnaire for tonic spasms, by both retrospectively reviewing medical records and performing clinical assessment. Results: All patients except one developed this symptom. The main triggering factors were sudden movements and emotional factors. Spasms were commonly associated to sensory disturbances and worsened during the acute phases of the disease. Carbamazepine was most commonly used to treat the symptom and patients showed good response to the drug. Conclusions: Tonic spasms are a common clinical manifestation in patients with neuromyelitis optica.Espasmos tônicos têm sido mais frequentemente associados com esclerose múltipla. Foram publicados até agora poucos relatos de série de pacientes com neuromielite óptica e espasmos tônicos. Métodos: Foram analisadas as características e a frequência de espasmos tônicos em 19 indivíduos com neuromielite óptica. Os dados foram coletados por meio de um questionário semiestruturado para espasmos tônicos, mediante a avaliação retrospectiva dos prontuários e a análise dos dados clínicos Resultados: Todos os pacientes com neuromielite óptica exceto um apresentaram espasmos tônicos. Os principais fatores desencadeantes foram movimentos bruscos e fatores emocionais. Espasmos foram frequentemente associados a perturbações sensoriais e se agravaram durante a fase aguda da doença. A carbamazepina foi utilizada frequentemente para tratar os sintomas, com boa resposta. Conclusões: Os espasmos tônicos são manifestações clínicas frequentes em pacientes com neuromielite óptica.

    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.

    Background. Overall bad prognosis of lung cancer is mostly due to too late detection of early lung cancer, which may be treated with good success. Therefore, different diagnostic methods are developing for more efficient detection of early lung cancer: besides modern radiological, bronchoscopic methods with additional fluorescence techniques, quantitative cytological investigations, also histological and molecular investigations are included. Histology may reveal early preinvasive lung cancer lesions, associated early during multistep lung carcinogenesis with molecular genetic changes. Patients and methods. Preinvasive epithelial lung cancer lesions we searched in two groups of patients. In the first group of 316 patients from the period March 2003 - August 2006, 498 bronchial and transbronchial biopsies were examined for squamous metaplasia and dysplasia, carcinoma in situ, and invasive tumours. In the second group of 238 patients from the period January 2004 - August 2006, resected primary lung tumours were analysed for preinvasive and invasive neuroendocrine tumours and atypical adenomatous hyperplasia. Results. The most frequent changes in bronchial and transbronchial biopsies were squamous metaplasia (46.5%), simple or goblet cell hyperplasia of the bronchial epithelium (44.3%), malignant tumours (20.66%) and squamous dysplasia (16.1%), but rare carcinoma in situ (0.63%). Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia was found in 15 (6.3%) cases in the vicinity of 238 resected lung cancer specimens, carcinoid in 12 patients (5%), and mostly combined large cell neuroendocrine cancer in 21 patients (8.8%). Atypical adenomatous hyperplasia was found in 2 patients. Conclusions. Classical histological analysis should be focused on detection of early preinvasive epithelial lung cancer lesions. Additional available molecular investigations may reveal gradual genetic changes characteristic for a series of the preinvasive epithelial histological changes

    Full Text Available Background/Aim. Impulse oscillometry (IOS is a method for estimating lung function which is used for early detection of bronchial hyperresponsiveness (BHR and asthma. The aim of the study was to determine the prevalence of BHR, the correlation between spirometry and IOS and sensitivity and specificity of IOS in proving BHR in patients with persistent allergic rhinitis. Methods. The study included 81 patients with allergic rhinitis. From all of them, medical history was taken, allergy testing was done, as well as measurements of parameters of lung function by the IOS and spirometry before and after nonspecific bronchial provocation test with histamin via Aerosol provocative system. Changes of the IOS parameters to fall in FEV1 of 20% were measured and compared with changes in the spirometry parameters. After bronchial challenge test subjects were divided into two groups: the group with BHR (group 1 and that without BHR (group 2. Results. The mean age of participants was 25.7 ± 5.7 years, and 50.5% were men. Out of the total number of subjects with allergy rhinitis, 56 (58.9% had a positive BPT. After bronchoprovocation an average increase in the group 1 was 88.15% for Rrs5, 111.98% for Fres, and for AX 819.69%. The high degree of correlation between the IOS and spirometry was proven in the group 2, while the whole group 1 had a weak correlation between parameters of these two methods. High sensitivity and low specificity for Rrs5 and Fres compared to FEV1 in diagnosing BHR was proven. Conclusion. The study demonstrated a high prevalence of BHR in the study group of patients with persistent allergic rhinitis, poor correlation in relation to the spirometric measurements in the group with BHR and a high sensitivity and low specificity of IOS for the detection of early changes in the airways.

    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.

    The laboratory rat has frequently been used as a human surrogate to estimate potential health effects following the inhalation of radioactive aerosol particles. Interspecies differences in biological response are commonly related to interspecies differences in particle deposition efficiencies. In addition, the documented site selectivity of bronchial carcinomas suggests that localized particle deposition patterns within bronchial airway bifurcations may have important implications for inhalation risk assessments. Interspecies differences in particle deposition patterns may be related primarily to differences in airway morphometries. Thus the validity of extrapolating rat deposition data to human inhalation conditions depends on their morphometric similarities and differences. It is well known that there are significant structural differences between the human - rather symmetric - and the rat - monopodial - airway systems. In the present approach, we focus on localized deposition patterns and deposition efficiencies in selected asymmetric bronchial airway bifurcations, whose diameters, lengths and branching angles were derived from the stochastic airway models of human and rat lungs (Koblinger and Hofmann, 1985;1988), which are based on the morphometric data of Raabe et al. (1976). The effects of interspecies differences in particle deposition patterns are explored in this study for two asymmetric bifurcation geometries in segmental bronchi and terminal bronchioles of both the human and rat lungs at different particle sizes. In order to examine the effect of flow rate on particle deposition in the human lung, we selected two different minute volumes, i.e., 10 and 60 1 min -1 , which are representative of low and heavy physical activity breathing conditions. In the case of the rat we used a minute volume of 0.234 1 min -1 (Hofmann et al., 1993)

    Increasing evidence suggests a functional role of RhoA/Rho-kinase signalling as a mechanism for smooth muscle contraction; however, little is known regarding the roles of Rac1 and other members of the Rho protein family. This study aimed to examine whether Rac1 modulates bronchial smooth muscle contraction. Ring preparations of bronchi isolated from rats were suspended in an organ bath, and isometric contraction of circular smooth muscle was measured. Immunoblotting was used to examine myosin light chain phosphorylation in bronchial smooth muscle. Our results demonstrated that muscle contractions induced by carbachol (CCh) and endothelin-1 (ET-1) were inhibited by EHT1864, a selective Rac1 inhibitor, and NSC23766, a selective inhibitor of Rac1-specific guanine nucleotide exchange factors. Similarly, myosin light chain and myosin phosphatase target subunit 1 (MYPT1) at Thr853 phosphorylation induced by contractile agonist were inhibited with Rac1 inhibition. However, contractions induced by high K + , calyculin A (a potent protein phosphatase inhibitor) and K + /PDBu were not inhibited by these Rac1 inhibitors. Interestingly, NaF (a G-protein activator)-induced contractions were inhibited by EHT1864 but not by NSC23766. We next examined the effects of a trans-acting activator of transcription protein transduction domain (PTD) fusion protein with Rac1 (PTD-Rac1) on muscle contraction. The constitutively active form of PTD-Rac1 directly induced force development and contractions were abolished by EHT1864. These results suggest that Rac1, activated by G protein-coupled receptor agonists, such as CCh and ET-1, may induce myosin light chain and MYPT phosphorylation and modulate the contraction of bronchial smooth muscle.

    BACKGROUND: It can be difficult to assess bronchial responsiveness in children because of their inability to perform spirometric tests reliably. In bronchial challenges lung sounds could be used to detect the required 20% fall in the forced expiratory volume in one second (FEV1). A study was undertaken to determine whether a change in lung sounds corresponded with a 20% fall in FEV1 after methacholine challenge, and whether the occurrence of wheeze was the most important change. METHODS: Fifteen children with asthma (eight boys) of mean age 10.8 years (range 8-15) were studied. All had normal chest auscultation before the methacholine challenge test. Lung sounds were recorded over the trachea for one minute and stored on tape. They were analysed directly and also scored blindly from the tape recording by a second investigator. Wheeze, cough, increase in respiratory rate, and prolonged expiration were assessed. RESULTS: The total cumulative methacholine dose causing a fall in FEV1 of 20% or more (PD20) was detected in 12 children by a change in lung sounds - in four by wheeze and in eight by cough, increased respiratory rate, and/or prolonged expiration. In two subjects altered lung sounds were detectable one dose step before PD20 was reached. In three cases in whom no fall in FEV1 occurred, no change in lung sounds could be detected at the highest methacholine dose. CONCLUSION: Changes in lung sounds correspond well with a 20% fall in FEV1 after methacholine challenge. Wheeze is an insensitive indicator for assessing bronchial responsiveness. Cough, increase in respiratory rate, and prolonged expiration occurs more frequently. PMID:8779140

  1. 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.

    To investigate the effect of education on self-evaluation and control level in patients with bronchial asthma. Seventy-five asthmatic patients with the initial diagnosis in line with the American Thoracic Society criteria, including 46 with junior high school education or below (group A) and 29 with senior high school education or above (group B), were asked to complete a survey to assess their symptoms and asthma attacks. Asthma control test (ACT) and peak expiratory flow rate (PEFR) evaluation were performed 8, 12 and 24 weeks after salmeterol/fluticasone therapy. Step-down treatment was administered according to GINA guidelines. The self-evaluation of the patients was assessed according to ACT score, physical signs and pulmonary function. An ACT score over 19 indicate well controlled condition. The effect of education on the self-evaluation and control level of bronchial asthma was assessed. The two groups had similar basal level of pulmonary function (FEV1). Eight weeks after the therapy, 29 patients in group A had ACT score over 19, including 11 with high control level; in group B, 17 had ACT score over 19, of whom 4 showed high control level. There was no significant difference between the two groups in control levels and self-evaluation (P>0.05). At 12 weeks, 37 patients in group A had ACT score over 19, with 17 having high control level; 22 patients in group B had ACT score over 19, 4 showing high control level; the two groups were similar in the control levels (P>0.05) but showed significant difference in self-evaluation (Pevaluation (Peducation level may play a role in self-evaluation and control level of bronchial asthma, but its impact differs in the course of the treatment.

    Respiratory diseases, including inflammatory airway disease (IAD), viral and bacterial infections, are common problems in exercising horses. The airway epithelium constitutes a major physical barrier against airborne infections and plays an essential role in the lung innate immune response mainly through toll-like receptor (TLR) activation. The aim of this study was to develop a model for the culture of equine bronchial epithelial cells (EBEC) in vitro and to explore EBEC innate immune responses in trained horses. Bronchial epithelial biopsies were taken from 6 adult horses during lower airway endoscopy. EBEC were grown in vitro by an explant method. The innate immune response of EBEC was evaluated in vitro by treatment with TLR ligands. TLR3 is the most strongly expressed TLR at the mRNA level in EBEC and stimulation of EBEC with Poly(I:C), an analog of viral dsRNA, triggers a strong secretion of IFN-β, TNF-α, IL-6 and CXCL8. We further evaluated the EBEC innate immune response in horses that underwent a 4-month-training program. While training had no effect on TLR mRNA expression in EBEC as well as in bronchial biopsies, it increased the production of IFN-β after stimulation with a TLR3 ligand and decreased the secretion of TNF-α and IL-6 after stimulation with a TLR2 and TLR3 ligand. These findings may be implicated in the increased risk for viral and bacterial infections observed in sport horses. Altogether, we report a successful model for the culture of EBEC that can be applied to the investigation of pathophysiologic conditions in longitudinal studies.

    Non-atopic asthma is the predominant phenotype in non-affluent parts of Latin America. We recently reported that infestation with Ascaris lumbricoides increased the risk of non-atopic asthma in less affluent areas of Brazil but the mechanism is unclear. The present study was conducted to determine whether helminth infestation is associated with heightened bronchial responsiveness (BHR), a common finding in asthma. A random sample of 50 asthmatic and 50 non-asthmatic controls (mean age 10.1 years) were selected from a larger cohort (n = 1,011) without knowledge of their helminth infestation status. Three stool samples were collected from each child on different days and each sample was analyzed by the Kato-Katz method for quantitative determination of helminth eggs. Bronchial provocation tests were performed with inhaled 4.5% hypertonic saline using the ISAAC Phase II standardized protocol. There was no difference between the prevalence of positive BHR in the asthmatics (20.4%) compared with the controls (14.6%) (P = 1.0). Helminth infestation was detected in 24.0% of children, with A. lumbricoides being the most common. Children with high load infestation (>or=100 eggs/g) were five times more likely to have BHR than children with low load or no infestation. Despite the small sample size the results of the present study suggest that the link between high load helminth infestation and non-atopic asthma may be mediated via heightened bronchial responsiveness, possibly due to an inflammatory response to the pulmonary phase of the helminth life cycle.

    To evaluate the long-term immediate effects of balloon dilatation of the tuberculous bronchial stenosis. Twenty-three women with tuberculous bronchial stenosis (19, left main bronchus ; 4, right main bronchus) underwent balloon dilatation (13 bronchoscopically guided ; 10 fluoroscopically guided). Immediate (n=23) and long-term follow-up (mean, 17.2 months; range, 1month-6years 3months ; n=20) assessments focused on changes in the results of the pulmonary function test (PFT). An increase in FVC or FEVI of more than 10% after the procedure was considered effective. In all patients, any complications were evaluated. Balloon dilatation was effective at immediate follow-up in 69.5% of patients(16/23) and in 75.0%(15/20) at long-term follow-up. Bronchoscopically and fluoroscopically-guided balloon dilatation proved effective in 61.5%(8/13) and 80.0% of patients(8/10) on immediate follow-up respectively, but in 90.0%(9/10) and 60.0%(6/10) on long term follow-up respectively. Balloon dilatation was effective in the active(n 10) and inactive(n = 13) stage of tuberculous bronchitis in 80.0%(8/10) and 61.5% of cases(8/13) on immediate follow-up respectively, but in 66.6%(6/9) and 81.8%(9/11) on long term follow-up study, respectively. On immediate follow-up, balloon dilatation of tubular bronchial stenosis was more effective in the active than in the inactive stage, but on long-term follow-up was less effective ; long-term improvement in the inactive stage was, however, well-maintained

    Purpose: This study's aim was to assess outcome and toxicity of high-dose-rate endoluminal brachytherapy (HDREB) for recurrent bronchial carcinoma. Methods and Materials: From 1987 to 2005, 41 patients were treated with HDREB for symptomatic recurrent bronchial carcinoma. All patients had previously undergone external beam radiotherapy (EBRT) with a median dose of 56 Gy (range, 30-70 Gy). The median HDREB dose applied was 15 Gy (range, 5-29 Gy). The median time interval between primary EBRT and reirradiation was 9 months (range, 2-54 months). Results: After a median follow-up of 6.7 months, the 6-, 12-, and 24-month overall survival rates were 58%, 18%, and 7%, respectively. The median overall survival time was 6.7 months. Local remission was achieved in 73% of patients (n = 30). A total of 24% of patients (n = 10) showed no response or progressive disease within 8 weeks after treatment. In 1 patient, treatment response was not documented. The 6-, 12-, and 24-month local control rates were 38%, 17%, and 3%, respectively. The median local progression-free survival time was 4 months (range, 1-23 months). Prognostic factors were a total dose of ≥15 Gy of HDREB (p = 0.029) and a Karnofsky performance score of ≥80% (p = 0.0012). The cause of death was locoregional progression in 27% of patients (n = 11), distant metastases in 24% of patients (n = 10), fatal hemorrhage in 15% of patients (n = 6), and other causes in 29% of patients (n = 12). None of the patients with locally controlled disease showed grade 3 or 4 late effects. Conclusions: Palliative treatment of symptomatic, locally recurrent bronchial carcinoma with HDREB can effectively relieve symptoms in the majority of patients while causing only few complications. Still, time to progression is short.

    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.)

    A 78-year-old male, observed for bronchial asthma, underwent two emergency operations within eight days. The first operation was performed under general anesthesia with tracheal intubation. Anesthesia was maintained by sevoflurane-oxygen and continuous infusion of propofol in combination with epidural injection of lidocaine. During the operation, respiratory sound was almost clear. But wheezing occurred as he awoke after discontinuation of the anesthetics. He needed ventilatory support for three days for status asthmatics. The second operation was performed under continuous spinal anesthesia using hypobaric tetracaine and hyperbaric bupivacaine. No ventilatory support was necessary after the operation and he was discharged uneventfully.

    Atmospheric cedar pollen in the southern region of Okayama Prefecture (situated in south-western Japan) has been counted since 1988. Pollen of different species of the Taxodiaceae family (Cryptomeria japonica, Sequoia sempervirens and Metasequoia glyptostroboides) and Japanese juniper (Juniperus rigida) in the Cupressaceae family, which are propagated mainly in the southern region of Okayama Prefecture, were found among the atmospheric pollen. Scratch tests using the pollen extract from Taxodiaceae and Cupressaceae were performed on children with bronchial asthma. Forty (25%) and 30 (18.8%) of the 160 patients reacted positively to an allergen extract from the pollen grains of Japanese cedar (Cryptomeria japonica) and Japanese juniper, respectively.

    66 patients with suspected bronchial tumors were examined by conventional tomography and by CT. The results were evaluated separately by two radiologists (A and B). All diagnoses were confirmed by bronchoscopy or surgery. In evaluating individual bronchi, conventional tomography had a sensitivity of 88% (A) or 87% (B) and a specificity of 97% (A) or 95% (B); CT had a sensitivity of 95% (A and B) and a specificity of 99% (A and B). If CT is available, our experience indicates that conventional tomography is no longer indicated. (orig.) [de

    Full Text Available In order to improve the self care abilities of the patients with bronchial asthma a ′Self Care Manual′ (a Booklet of 26 pages on bronchial asthma was prepared. 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 fraction of exhaled nitric oxide (FeNO) is an established marker of airway inflammation in asthma. Nasal nitric oxide (nNO) has initially been regarded as a promising marker of inflammation of nasal mucosa. However, due to its dual origins, paranasal sinuses and nasal mucosa, the clinical use of nNO is controversial. There is an inflammatory link between inflammation in the upper and lower airways within the united airways' paradigm, but the study of the clinical value of nNO in asthma has been limited. The objective of this study is to analyse nNO in asthmatics and its relationship to FeNO, bronchial hyperresponsiveness, allergic sensitization and asthma control. A total of 371 children and young adults from an asthma cohort were included in this study, which performed measurements of nNO (through aspiration at 5 mL s(-1)), FeNO, bronchial responsiveness to methacholine, blood eosinophil count (B-Eos) and IgE sensitization. The asthma control test (ACT) and a questionnaire regarding medical treatment, symptoms of asthma, rhinitis and chronic rhinosinusitis were completed by all subjects. An association was found between higher nNO levels and increased bronchial responsiveness (p < 0.001), FeNO (p < 0.001) and B-Eos (p = 0.002). Sensitization to furry animals related to higher levels of nNO (p < 0.001). Subjects with poorly controlled asthma (ACT < 15) had lower levels of nNO than subjects with a higher ACT score (619 ± 278 ppb, versus 807 ± 274 ppb, p = 0.002). Loss of smell showed the strongest association with lower nNO levels among the upper airway symptoms recorded. In patients with asthma, nNO was positively correlated with exhaled NO, bronchial responsiveness and asthma control. This study suggests clinical utility of nNO in subjects with asthma, but in order to get better understanding of the nNO determinants, simultaneous mapping of upper airway comorbidities by clinical examination is appropriate.

    Full Text Available Background & aim: In recent decades, the use of media education to control the problems of patients with chronic diseases has been taken into consideration by medical staff, but few studies have been done on their effectiveness in improving the quality of sleep in patients with bronchial asthma. The aim of this study was to determine the effect of film-based education on sleep quality in patients with bronchial asthma.   Methods: The present study was a quasi-experimental study and all of the patients with bronchial asthma referred to the Asthma clinic of Boroujen were included in this study. Fifty one patients who were eligible for inclusion in the study were selected by non probability sampling method. The samples were assigned to randomly assigned blocks between the two test and control groups. For patients in the test group, patient education was performed through a 15-minute video clip by computer, DVD player and mobile phone, but patients in the control group only received routine care. The Pittsburgh Sleep Quality Index questionnaire was used to collect data one week before intervention and one month after intervention. The collected data were analyzed by descriptive statistics and t-test, Chi-square, Mann-Whitney and Wilcoxon tests.   Results: There was no significant difference before the intervention, in the overall score of sleep quality and its dimensions in the two groups (p = 0.66. There was a significant difference between the two groups after the intervention in the general score of sleep quality and the dimensions of sleep quality, sleep disturbances and sleep latency (p = 0.001 However, there was no significant difference in the use of sleep apnea, sleep duration, adequacy of sleep and daily dysfunction in the test and control groups.   Conclusion: The movie-based instruction has been able to improve the quality of sleep in patients with bronchial asthma. Considering the ease of implementation of this educational method

    Purpose: A prospective study to evaluate the diagnostic potential and limitations of three fast MRI sequences in patients with bronchial carcinoma based on the comparison with spiral CT. Material and methods: Three fast chest MRI sequences from 20 patients with central or peripheral bronchial carcinoma were evaluated by two observers for relation of tumour to adjacent structures, lymph node enlargement, additional pulmonary lesions and artefacts. The information from MR-imaging was compared with the results from spiral CT. MRI comprised a T1-3D-GRE breath-hold examination ('VIBE', TR/TE 4.5/1.9 ms, flip-angle 12 deg., matrix 502 x 512, 2.5 mm coronal slices), a breath-hold, T2-HASTE sequence (TR/TE 2000/43 ms, matrix 192 x 256, 10 mm coronal slices) and a respiration-triggered T2-TSE sequence (TR/TE 3000-6000/120 ms, matrix 270 x 512, 6 mm transverse slices). The FOV was adapted individually (380-480 mm). Results: The presence of the primary bronchial carcinoma and infiltration of thoracic structures by tumour tissue could be demonstrated by all sequences. VIBE sequence was more suitable for detecting small pulmonary nodules than the other MRI examinations, but compared to CT still 20% of these lesions were missed. Contrary to VIBE and T2-weighted TSE scans, HASTE sequence was limited in imaging mediastinal lymph nodes due to missing relevant findings in 2/20 patients. HASTE images significantly provided the lowest rate of artefacts in imaging lung parenchyma (P < 0.001 in peripheral parenchyma), but spatial resolution was limited in this sequence. Concerning the differentiation between tumour and adjacent atelectasis (n = 8), T2-weighted TSE imaging was superior to CT and VIBE in all cases and to HASTE sequence in 4/8 patients. Conclusion: The combination of VIBE and HASTE sequence allows for an adequate imaging of thoracic processes in patients with bronchial carcinoma, limited only in visualizing small pulmonary nodules. To obtain more detail resolution and to

    A therapeutic method including extracorporeal x-ray irradiation of the autoblood of patients with bronchial asthma complicated by cortisone dependence and polyvalent drug intolerance, has been elaborated and clinically tested. The use of this method brings about good short-term results in 90% of cases and good long-term results in 40% of cases (14-38 months). It provides an opportunity to give up corticosteroids in more than 60% of patients and to decrease the hormone dose in the rest of cortisone-dependent patients with bronchial asthma. The above therapeutic method can be used as an independent type of treatment, especially in the presence of polyvalent drug allergy and as an element of multiple modality therapy of bronchial asthma patients. The method was used under in-patient conditions only. No side effects were marked in the course of the clinical trial. To carry out this type of therapy, patients should be thoroughly screened

    Full Text Available The article presents a generalized 2-year Russian experience in the application of monoclonal antibodies to IgE in children and adolescents with severe, resistant to standard treatment of bronchial asthma. Data on 65 patients treated with anti-IgE therapy with omalizumab within more than 6 months period in 6 centers of the Russian Federation from 2007 to 2010 were analyzed. The results of this analysis demonstrate the safety and high clinical effectiveness of anti-IgE-therapy in children and adolescents with severe uncontrolled atopic bronchial asthma. Full control of the disease or marked improvement can be achieved in 73% patients, the effect in most cases significantly increases during the first 6 months of treatment and becomes stable in the future, providing a good quality of life and normal lung function.Key words: bronchial asthma, anti-IgE-therapy, treatment, adolescents, children, quality of life, omalizumab.

    Objective: To discuss the clinical application of radiofrequency ablation combined with bronchial artery infusion of docetaxel in treating non-small cell lung cancer and to summarize the experience of using this therapy in clinical practice. Methods: Radiofrequency ablation was performed in twenty-one patients with lung cancer. The diagnosis was confirmed by CT-guided percutaneous needle biopsy or bronchoscopic biopsy in all patients. One week after radiofrequency ablation treatment, bronchial artery infusion of docetaxel was conducted. The therapeutic results were observed and evaluated. Results: After the treatment, the lesion's size was markedly reduced and the clinical symptoms were dramatically improved in all patients. Conclusion: Radiofrequency ablation combined with bronchial artery infusion of docetaxel is a safe, effective and simple technique with excellent therapeutic results for the treatment of non-small cell lung cancer. It is really worth popularizing this technique in clinical practice. (authors)

    Inflammation of the human bronchial epithelium, as observed in asthmatics, is characterized by the selective death of the columnar epithelial cells, which desquamate from the basal cells. Tissue repair initiates from basal cells that resist inflammation. Here, we have evaluated the extent of apoptosis as well as the Hsp27 level of expression in epithelial cells from bronchial biopsy samples taken from normal and asthmatic subjects. Hsp27 is a chaperone whose expression protects against oxidative stress. We report that in asthmatic subjects the basal epithelium cells express a high level of Hsp27 but no apoptotic morphology. In contrast, apoptotic columnar cells are devoid of Hsp27 expression. Moreover, we observed a decreased resistance to hydrogen peroxide–induced apoptosis in human bronchial epithelial 16–HBE cells when they were genetically modified to express reduced levels of Hsp27.
