1/31. Severe exertional dyspnea in a patient with localized emphysema.The case of a middle-aged, male smoker who presented with progressive severe dyspnea is described. The cause of the progressive severe dyspnea remained unexplained after a comprehensive history, physical examination, chest radiograph, electrocardiogram and spirometry. Subsequent investigations resulted in a diagnosis of localized pulmonary emphysema. Detailed exercise testing helped uncover the physiological basis of the patient's extreme dyspnea.- - - - - - - - - - ranking = 1keywords = physical examination, physical (Clic here for more details about this article) |
2/31. Too hot to handle: an unusual exposure of HDI in specialty painters.BACKGROUND: Hexamethylene Diisocyanate (HDI) is a color stable aliphatic isocyanate that is used in specialty paints as a hardener. Due to the lower vapor pressure of its commercial biuret form, it is considered a relatively "safe" isocyanate from an exposure standpoint. This case series reports on an unusual toxic exposure to HDI. Between November 1993 and May 1994, seven specialty painters and one boiler maker who were working at three different power plants were examined at the Institute of Occupational and environmental health at west virginia University. At their respective work sites, HDI was applied to the hot surfaces of boilers that were not shut down, and allowed sufficient time to cool. Consequently, these workers were exposed to volatile HDI and its thermal decomposition products. methods: All of these workers underwent a complete physical examination, spirometry, and methacholine challenge testing. RESULTS: All 8 workers complained of dyspnea, while 4 of the 8 also complained of rash. On examination 3 workers were methacholine challenge positive and 2 had persistent rash. At follow-up 4 years later, 5 workers still had to use inhalation medication and one had progressive asthma and dermatitis. All 8 workers, by the time of the follow-up, had gone through economic and occupational changes. CONCLUSIONS: This case series reports on an unusual exposure to HDI. It is unusual in that: 1) There were two simultaneous sentinel cases with two different material safety data sheets (MSDS) for the same product, 2) Exposure was to volatile HDI and its decomposition products and 3) Hazardous conditions of exposure occurred at three different sites.- - - - - - - - - - ranking = 1keywords = physical examination, physical (Clic here for more details about this article) |
3/31. pneumothorax complicating pulmonary emphysema.Clinical and roentgenographic findings were compared in patients 40 years of age and over and in those under 40 who were treated for acute unilateral pneumothorax. dyspnea and anxiety were pominent in the older individuals, although pneumothoraces were usually small. Because physical findings were often unreliable, roentgenograms were required. In the presence of pulmonary emphysema, loss of retractility prevented total collapse of the underlying lung. Increased intrapleural pressure caused over-expansion of the chest wall and the depression of the diaphragm without much mediastinal shifting. Partial collapse of emphysematous lobes demonstrated bullae that were not previously obvious. Respiratory failure developed in five patients over 40 years of age, but four of them recovered after relief of the pneumothorax. mortality for the group was low and related to associated pulmonary diseases.- - - - - - - - - - ranking = 0.10600717806011keywords = physical (Clic here for more details about this article) |
4/31. dyspnea lusoria: compression of the pulmonary artery by a Kommerell's diverticulum.We report a rare case of Kommerell's diverticulum presenting as dyspnea on exertion. After careful physical examination, selective imaging tests demonstrated a significant flow abnormality in the left pulmonary artery caused by an aneurysm of the descending aorta in the area of the ligamentum arteriosum.- - - - - - - - - - ranking = 1keywords = physical examination, physical (Clic here for more details about this article) |
5/31. The iowa follow-up of chemically sensitive persons.Clinical symptoms and self-reported health status in persons reporting multiple chemical sensitivities (MCS) are presented from a 9-year follow-up study. Eighteen (69%) subjects from a sample of 26 persons originally interviewed in 1988 were followed up in 1997 and given structured interviews and self-report questionnaires. In terms of psychiatric diagnosis, 15 (83%) met DSM-IV criteria for a lifetime mood disorder, 10 (56%) for a lifetime anxiety disorder, and 10 (56%) for a lifetime somatoform disorder. Seven (39%) of subjects met criteria for a personality disorder using the personality Diagnostic Questionnaire-IV. Self-report data from the illness behavior Questionnaire and Symptom checklist-90-Revised show little change from 1988. The 10 most frequent complaints attributed to MCS were headache, memory loss, forgetfulness, sore throat, joint aches, trouble thinking, shortness of breath, back pain, muscle aches, and nausea. Global assessment showed that 2 (11%) had "remitted", 8 (45%) were "much" or "very much" improved, 6 (33%) were "improved", and 2 (11%) were "unchanged/worse". Mean scores on the SF-36 health survey showed that, compared to U.S. population means, subjects reported worse physical functioning, more bodily pain, worse general health, worse social functioning, and more emotional-role impairment; self-reported mental health was better than the U.S. population mean. All subjects maintained a belief that they had MCS; 16 (89%) acknowledged that the diagnosis was controversial. It is concluded that the subjects remain strongly committed to their diagnosis of MCS. Most have improved since their original interview, but many remain symptomatic and continue to report ongoing lifestyle changes.- - - - - - - - - - ranking = 0.10600717806011keywords = physical (Clic here for more details about this article) |
6/31. chiropractic management of chronic chest pain using mechanical force, manually assisted short-lever adjusting procedures.OBJECTIVE: To discuss a case involving a patient with chronic chest pain, dyspnea, and anxiety. Although resistant to previous treatment regimens, the condition responded favorably to chiropractic manipulation of the costosternal articulations. CLINICAL FEATURES: A 49-year-old man had chronic chest pain, dyspnea, and anxiety for over 4 months. The severity of the condition gradually progressed to the point of precluding the patient's active employment and most physical activity. Prior efforts to treat the condition had met with failure. INTERVENTION AND OUTCOME: The patient received mechanical force, manually assisted short-lever chiropractic adjustment of the thoracic spine and, in particular, the costosternal articulations. Adjustments were by means of an Activator Adjusting Instrument II. The patient responded favorably to the intervention, obtaining prompt relief from his symptoms. Sustained chiropractic care rendered over a 14-week period resulted in complete resolution of the patient's previously chronic condition, with recovery maintained at 9-month follow-up. CONCLUSIONS: Certain types of chest pain may have their etiology in a subluxation complex involving the costosternal articulation. Although the possibility of myocardial involvement must be considered with all patients whose symptoms include chest pain, a musculoskeletal involvement, including costosternal subluxation complex, may be the underlying cause of the symptoms in certain patients. When this is the case, chiropractic adjustment may provide an effective mode of treatment. Further study in an academic research venue is merited to investigate the role that conservative chiropractic care can provide for patients with chest pain.- - - - - - - - - - ranking = 0.10600717806011keywords = physical (Clic here for more details about this article) |
7/31. Idiopathic spontaneous pneumomediastinum: an uncommon emergency in children.Spontaneous pneumomediastinum (SPM) occurs rarely in children. The diagnosis is based on physical examination and chest radiography. Conservative therapy usually leads to recovery. However, SPM in association with severe hypoxia, tachycardia, metabolic acidosis, and high ventilation pressures indicates clinically significant tension in the mediastinum. A collar mediastinotomy is the treatment of choice in these circumstances.- - - - - - - - - - ranking = 1keywords = physical examination, physical (Clic here for more details about this article) |
8/31. Severe hyperphosphatemia and hypocalcemia following the rectal administration of a phosphate-containing Fleet pediatric enema.BACKGROUND: Toxicity secondary to rectally administered hypertonic phosphate solution in patients with normal renal function is rarely reported in the literature. We report a case of electrolyte disturbance and seizure secondary to the rectal administration of 2 Fleet pediatric enemas. CASE REPORT: A 4-year-old white female with spinal muscular atrophy and chronic constipation was brought to the emergency department with complaints of lethargy and difficulty breathing following the administration of 2 Fleet pediatric enemas. In the emergency department, physical examination was significant for a depressed level of consciousness and shallow respirations. A basic metabolic profile was significant for a calcium of 3.3 mg/dL, phosphate of 23 mg/dL, and sodium of 153 mEq/L. Arterial blood gases revealed a pH of 7.24, Pco2 of 38 mm Hg, Po2 of 220 mm Hg. Electrocardiogram revealed a prolonged QT interval of 340 milliseconds with a corrected QT interval of 498 milliseconds. Sixteen hours postexposure, she experienced a generalized seizure unresponsive to multiple doses of lorazepam and responsive only to 100 mg of intravenous calcium chloride. Two days after presentation, the patient experienced complete resolution of symptoms. CONCLUSION: Osmotically acting hypertonic phosphate enemas can result in severe toxicity if retained. This is true even in patients without predisposing risk factors.- - - - - - - - - - ranking = 1keywords = physical examination, physical (Clic here for more details about this article) |
9/31. Cases from the Osler Medical Service at Johns Hopkins University. diagnosis: P. carinii pneumonia and primary pulmonary sporotrichosis.PRESENTING FEATURES: A 53-year-old man who had human immunodeficiency virus (hiv) presented to the Johns Hopkins Hospital with a 3-month history of increasing dysphagia, cough, dyspnea, chest pain, and an episode of syncope. His past medical history was notable for oral and presumptive esophageal candidiasis that was treated with fluconazole 6 months prior to presentation. Three months prior to presentation, he discontinued his medications, and his symptoms of dysphagia recurred. During that time he developed intermittent fevers and chills, progressively worsening dyspnea on exertion, and a cough productive of white sputum. He also reported a 40-lb weight loss over the past 3 months. On the day prior to presentation, he had chest pain and shortness of breath followed by weakness, dizziness, and a brief syncopal episode. He denied orthopnea, paroxysmal nocturnal dyspnea, lower extremity edema, jaundice, hemoptysis, hematemesis, melena, hematochezia, or diarrhea. There was no history of alcohol use, and he stopped smoking tobacco approximately 1 month previously. He smoked cocaine but denied injection drug use. The patient had never been on antiretroviral therapy and had never had his CD4 count or viral load measured. On physical examination, the patient was a thin, cachectic man who appeared older than his stated age. His vital signs were notable for blood pressure of 102/69 mm Hg, resting tachycardia of 102 beats per minute, resting oxygen saturation of 92% on room air, normal resting respiratory rate, and a temperature of 38.1 degrees C. His oropharynx was clear, with no signs of thrush or mucosal ulcers. His pulmonary examination was notable for diminished breath sounds in the lower lung fields bilaterally. Cardiac, abdominal, and neurologic examinations were normal. His skin was intact, with no visible petechiae, rashes, nodules, or ulcers. Laboratory studies showed a total white blood cell count of 3.2 x 10(3)/microL, with a total lymphocyte count of 330/microL, hematocrit of 30.2%, a serum sodium level of 129 mEq/L, and a serum lactate dehydrogenase level of 219 IU/L. The patient had an absolute CD4 count of 8 cells/mm3 and a hiv viral load of 86,457 copies/mL. His arterial blood gas on room air had a pH of 7.51, a PCO2 of 33 mm Hg, and a PO2 of 55 mm Hg. Electrocardiogram and serial serum cardiac enzymes were normal. A chest radiograph showed bilateral upper lobe patchy infiltrates with left upper lobe consolidation. Computed tomographic (CT) scan of the chest with contrast showed bilateral ground glass infiltrates with focal consolidation (Figure 1) and no evidence of pulmonary embolism. Induced sputum was negative for pneumocystis carinii, fungi, or acid-fast bacilli. A bronchoalveolar lavage was performed.

10/31. Improving dyspnea management in three adults with chronic obstructive pulmonary disease.This case report describes occupational therapy intervention for three adult outpatients with chronic obstructive pulmonary disease (COPD) at one large urban hospital. The occupational therapy intervention was based on the Management of dyspnea Guidelines for Practice (Migliore, in press). The learning and practice of controlled breathing were promoted in the context of physical activity exertion in a domiciliary environment. In addition to promoting dyspnea management, the controlled-breathing strategies aimed to facilitate energy conservation and to increase perceived breathing control. Although no causality can be determined in a case study design, the patients' dyspnea with activity exertion decreased and their functional status and quality of life increased following goal-directed, individualized occupational therapy intervention combined with exercise training.- - - - - - - - - - ranking = 0.10600717806011keywords = physical (Clic here for more details about this article) |
