1/32. Pneumoparotid due to spirometry.Pneumoparotid has been described in patients who generate increased intraoral pressures when playing wind instruments, while coughing, and when undergoing dental work. Some patients have intentionally created pneumoparotid to avoid duties at school or in the military, or to gain attention. We describe a patient who developed pneumoparotid during pulmonary function testing. The diagnosis of pneumoparotid depends on a suggestive clinical situation and glandular swelling with or without crepitus. observation of aerated saliva per Stensen's duct or air in the parotid duct and/or gland by any imaging study is diagnostic if infection with a gas-forming organism can be reasonably excluded. No specific treatment is required, other than the avoidance of predisposing activities.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
2/32. Chronic eosinophilic pneumonia: a case report.Chronic eosinophilic pneumonia (CEP) is a disorder, characterized by a history of pneumonia (> 2 months) and eosinophilic pulmonary infiltration without any organic causes. We describe a 28-year-old woman who presented with cough, dyspnea and fever for 2 months. She was diagnosed with mild asthma and allergic rhinitis 2 years before being diagnosed with CEP. For a period of 9 months she took no medication. Her chest roentgenogram at this admission revealed patchy infiltration in both upper lung fields. Laboratory data revealed blood eosinophilia (4,284/mm3), and her serum IgE was mildly elevated (245.8 IU/ml). A computerized tomography of the chest did not show bronchiectasis. CEP was diagnosed from significant eosinophilia in bronchoalveolar larvage fluid and transbronchial biopsy revealed eosinophilic infiltration without any demonstrable infectious agent. The patient was treated with prednisolone 45 mg/day. Her symptoms disappeared and her chest roentgenogram showed nearly complete resolution in 2 and 4 days, consecutively.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
3/32. Myelodysplastic syndrome with monosomy 7 and pulmonary aspergillosis.A 43-year-old man with no past history presented with symptoms of fever, cough and dyspnoea arising from invasive pulmonary aspergillosis and was found to have myelodysplastic syndrome with monosomy 7. Before initiation of chemotherapy, he deteriorated rapidly, developing multi-organ failure requiring mechanical ventilation, and he eventually succumbed despite amphotericin b treatment. The importance of monosomy 7 in determining immune function in patients with myelodysplastic syndrome is emphasised.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
4/32. Acute interstitial pneumonitis. Case series and review of the literature.Acute interstitial pneumonitis (AIP) is an acute, idiopathic interstitial lung disease characterized by rapidly progressive diffuse pulmonary infiltrates and hypoxemia requiring hospitalization. The case-fatality ratio is high. Previous reports suggested that survivors of the acute event have a favorable outcome. We undertook this study to examine the natural history of survivors. We had observed several patients who experienced recurrent episodes of AIP and chronic progressive interstitial lung disease. We sought to determine longitudinal survival in these patients and to compare our experience with that in the medical literature. overall, we identified 13 biopsy-proven cases of AIP. The mean patient age was 54 years in our review, which is identical to previous reports. Twelve patients were hospitalized and all 12 required mechanical ventilation. overall hospital survival was 67%. All patients demonstrated abnormalities in gas exchange at presentation. Radiographs typically demonstrated bilateral patchy densities that progressed to a diffuse alveolar filling pattern in nearly all cases. All biopsy specimens showed organizing diffuse alveolar damage. Longitudinal data were available for 7 patients. Two died of AIP recurrences. A third died of complications of heart failure shortly after hospital discharge. One patient progressed to end-stage lung disease and required lung transplantation. Two patients experienced persistent pulmonary symptoms, accompanied in 1 by progressive lung fibrosis. One patient had nearly complete recovery of lung function 2 years following AIP. (Follow-up information was unavailable for 2 survivors.) In our literature review, 5 of 7 patients reported experienced some recovery of lung function. One case of progressive interstitial lung disease requiring lung transplantation was reported. The reported mortality was much higher than in our experience (74% versus 33%). The mean time from symptom onset to death was 26 days, compared with 34 days in our experience. The use of corticosteroids did not appear to influence survival, although this has not been tested in a rigorous manner. The better survival in our series may be related in part to a survivor selection bias. In contrast to previous reports, we found that survivors of AIP may experience recurrences and chronic, progressive interstitial lung disease. We did not identify any clinical or pathologic features that predict mortality in these patients. Likewise, there were no features that predicted the longitudinal course in survivors. Further study to identify causal factors is required in the hope of preventing morbidity and mortality related to this disease.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
5/32. Spontaneous compressive orbital emphysema of rhinogenic origin.We report the case of a young patient who developed spontaneous compressive orbital emphysema after an attack of coughing. At admission the patient presented left proptosis, diplopia, vision impairment and headache. Computer tomography showed air in the lateral part of left orbit compressing the eyeball and the optic nerve medially. It also revealed a sphenoid bone dysplasia with hyperpneumatization of the left greater wing and with two dehiscences in its wall. It was very intriguing to discover that this sphenoid dysplasia and the flap of mucosa covering one dehiscence were causing a ball-valve effect, allowing air to enter but not leave the orbit. Endoscopic sinus surgery was successfully used to treat this case.- - - - - - - - - - ranking = 6.3832438195375keywords = nerve (Clic here for more details about this article) |
6/32. Late presentation of Bochdalek hernia: clinical and radiological aspects.Three infants with late presentation of Bochdalek hernia are presented. The presenting symptoms were cough, intermittent vomiting, dyspnea, and cyanosis. Initial diagnoses of isolated paravertebral mass and foreign material aspiration were made in two infants, based on plain chest x-ray findings and history of the patients. Further radiological investigations, such as contrast upper gastrointestinal series or enema, computerized tomography, and magnetic resonance imaging of the chest, suggested the diagnosis of Bochdalek hernia. The hernia was found on the left side in two patients and on the right side in one. At operation, the stomach, small intestine, and spleen were found as herniated organs in one patient, ascending colon in one, and all of the small intestine together with ascending colon in the other. A congenital diaphragmatic defect should be suspected in every child presenting with unusual respiratory or gastrointestinal symptoms and with abnormal chest x-ray findings. The radiological findings vary greatly from one case to another, and even in the same case at different times because of differences in herniated organs and intermittent spontaneous reduction. The possibility of congenital diaphragmatic hernia should be kept in mind to avoid a wrong diagnosis, undue delay in diagnosis, and inappropriate treatment.- - - - - - - - - - ranking = 2keywords = organ (Clic here for more details about this article) |
7/32. Psychogenic cough in adults: a report of two cases and review of the literature.Psychogenic cough, also known as "habit cough," is a well-documented condition in the pediatric and adolescent population, with numerous cases reported in the medical literature. Many of these patients are strikingly similar in their clinical characteristics and, although the data are limited, a variety of treatment options may be successful in terminating this form of cough. However, psychogenic cough in adults has been reported infrequently and is less well defined. We report two cases of psychogenic cough in adult patients referred to our service for an evaluation of refractory, chronic cough and review the relevant medical literature. Our patients seemingly represent the first cases of psychogenic cough reported in the geriatric population and share clinical features with children, adolescents, and young adults. One case is unique in the sense that the cough responded to a distracter in the form of a throat lozenge, and this patient consumed > or = 20 lozenges/day for approximately 13 years. Psychogenic cough should be considered in adult patients who present with a chronic cough of no obvious organic basis that has failed therapy directed at postnasal drip, asthma, and gastroesophageal reflux. We propose criteria to assist in making a diagnosis of psychogenic cough in adult patients and review the limited information that exists concerning treatment modalities.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
8/32. Systematic reviews of infectious diseases.The World Wide Web provides ready access to a wealth of information on infectious diseases topics. Systematic reviews and practice guidelines help to focus that evidence with in-depth literature analysis of a specific question. These reviews are typically rigidly structured, often periodically updated, and include critical evaluation of available data. In this article, Web sites of organizations that publish systematic reviews and practice guidelines for infectious diseases are identified and reviewed with regard to ease of use, comprehensiveness, quality of information, and cost. Examples of information available in databases of practice guidelines and systematic reviews are provided. A hypothetical case is used to illustrate the use of electronic resources in evidence-based infectious diseases practice.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
9/32. Should supraclavicular brachial plexus block be avoided in pregnancy?Unilateral phrenic nerve block is common after supraclavicular brachial plexus block techniques, although it is rarely symptomatic in patients without respiratory disease. A 24-weeks-pregnant woman was scheduled for a carpal tunnel release because of intractable pain. After a perivascular subclavian brachial plexus block with 30 ml of 0.33% plain bupivacaine was performed, the patient developed a right phrenic nerve block manifested by acute dyspnea and cough. No deleterious consequences followed, but surgery was canceled. Respiratory changes produced by pregnancy might compromise ventilatory reserve. Thus, we suggest avoiding supraclavicular approaches to brachial plexus block in pregnant women, since they may be as prone to developing respiratory embarrassment, secondary to phrenic block, as patients with pulmonary pathology.- - - - - - - - - - ranking = 12.766487639075keywords = nerve (Clic here for more details about this article) |
10/32. Pulmonary lymphohistiocytic reactions temporally related to etanercept therapy.This report details the pulmonary pathologic findings in four patients with rheumatoid arthritis, who developed new onset of pulmonary signs and symptoms with alveolar infiltrates temporally related to the institution of etanercept therapy. biopsy findings showed an interstitial and air space lymphohistiocytic infiltrate with non-necrotizing granulomas, in the setting of negative cultures and special stains for microorganisms. The association with etanercept therapy and granulomatous reactions is discussed along with the differential diagnosis.- - - - - - - - - - ranking = 1keywords = organ (Clic here for more details about this article) |
