A 17-year-old girl presented pain and subcutaneous crepitation in the left hand. Because of lack of systemic symptoms, non-infectious cause was considered. Radiographic and magnetic resonance imaging revealed subcutaneous emphysema. A chest x-ray was reported as normal but chest computerised tomography revealed pneumomediastinum. On the third day of the hospitalisation, subcutaneous emphysema spread to arm, shoulder, head, left hemithorax, back, bilateral supraclavicular, cervical, submandibular and periorbital regions. Pneumomediastinum and subcutaneous emphysema disappeared during 6 weeks of follow up with conservative methods. This might have prevented unnecessary surgical intervention. This report demonstrates that benign non-infectious subcutaneous emphysema of the hand due to pneumomediastinum should be kept in mind in hand surgery.

Transdermal fentanyl is effective and well tolerated for the treatment of chronic pain caused by malignancy and non-malignant conditions when administered according to the manufacturer's recommendations. Compared with oral opioids, the advantages of transdermal fentanyl include a lower incidence and impact of adverse effects (constipation, nausea and vomiting, and daytime drowsiness), a higher degree of patient satisfaction, improved quality of life, improved convenience and compliance resulting from administration every 72 hours, and decreased use of rescue medication. Transdermal fentanyl is a useful analgesic for cancer patients who are unable to swallow or have gastrointestinal problems. Transdermal fentanyl forms a depot within the upper skin layers before entering the microcirculation. Therapeutic blood levels are attained 12-16 hours after patch application and decrease slowly with a half-life of 16-22 hours following removal. Patients with chronic pain should be titrated to adequate relief with short-acting oral or parenteral opioids prior to the initiation of transdermal fentanyl in order to prevent exacerbations of pain or opioid-related adverse effects. Transdermal fentanyl can then be initiated based on the 24-hour opioid requirement once adequate analgesia has been achieved. The prolonged elimination of transdermal fentanyl can become problematic if patients develop opioid-related adverse effects, especially hypoventilation. Adverse effects do not improve immediately after patch removal and may take many hours to resolve. Patients who experience opioid-related toxicity associated with respiratory depression should be treated immediately with an opioid antagonist such as naloxone and closely monitored for at least 24 hours. Because of the short half-life of naloxone, sequential doses or a continuous infusion of the opioid antagonist may be necessary. Transdermal fentanyl should be administered cautiously to patients with pre-existing conditions such as emphysema that may predispose them to the development of hypoventilation. Transdermal fentanyl is indicated only for patients who require continuous opioid administration for the treatment of chronic pain that cannot be managed with other medications. It is contraindicated in the management of acute and postoperative pain, as pain may decrease more rapidly in these circumstances than fentanyl blood levels can be adjusted, leading to the development of life-threatening hypoventilation. Cognitive and physical impairments such as confusion and abnormal co-ordination can occur with transdermal fentanyl. Therefore, patients should be instructed to refrain from driving or operating machinery immediately following the initiation of transdermal fentanyl, or after any dosage increase. Patients may resume such activities once the absence of these potential adverse effects is documented.

We describe a case of pneumomediastinum and subcutaneous emphysema during labour. The patient had previously received an epidural anaesthesia to alleviate labour pain. We found several reports of subcutaneous emphysema and pneumomediastinum (or pneumothorax) possibly caused by or related to epidural anaesthesia use, but conclude that the epidural anaesthesia was probably not a cause in our case.

Pneumomediastinum and cervical emphysema usually occur following esophageal or chest trauma. Rarely do they occur as a complication of childbirth, and only approximately 200 such cases have been reported in the literature worldwide. We describe a new case, and we review the clinical picture, pathophysiology, and management of these conditions. In view of the head and neck symptoms of pneumomediastinum and cervical emphysema during labor--which include dyspnea, cough, sore throat, pain on swallowing, and dysphagia--otolaryngologists might be consulted and should therefore be aware of these conditions in order to recognize and treat them.

Subcutaneous emphysema and pneumomediastinum is a rare complication of dental treatment. Our case report describes a case secondary to dental drilling with a high-speed air drill, and diffusion of the compressed air. Our case had the classical clinical features of sudden subcutaneous emphysema starting in the face, and subsequently extending into the neck and thorax, accompanied by severe pain and dyspnoea. Rapid medical treatment for this emergency avoided the surgical decompression.

We present a 76-year-old patient who had ocular trauma with dehiscence of the wound and scleral rupture with a prolapsed iris, ciliary body, intraocular lens, and vitreous after uneventful cataract surgery with a self-sealing sclerocorneal tunnel incision. General anesthesia was not possible because the patient had a history of lung cancer with extensive emphysema and unstable coronary disease. Local retrobulbar or peribulbar anesthesia was not considered because of the risk for further extrusion of intraocular contents. Topical anesthesia was applied with a 10.0 mm x 2.5 mm cellulose sponge soaked in oxybuprocaine 0.4% (Novesine) placed under the upper and lower lid for 20 minutes. Surgical repair of a 14.0 mm scleral wound was achieved without complication or pain during the procedure.

Emphysematous changes are common in the general population. A significant number of these patients requires surgical interventions. Lung volume reduction surgery (LVRS) rapidly gained popularity without a sufficient evidence of beneficial outcome; the presumed mechanism of improvement in lung function is secondary to re-expansion of more normal, underlying compressed lung. The NETT study proposed to evaluate effectiveness of medical treatment vs LVRS in patients with severe bilateral emphysema. Complete results of the NETT study are unknown yet, but there are evidences of beneficial effects of LVRS, at least in a short term. The anesthetic management of these patients includes the continuation of the bronchodilator therapy till surgery, the use of steroids and antisialologue. Pain relief must be optimal and mobilization must be early. One lung ventilation is an absolute necessity, achieved with double lumen tube insertion.

A nationwide survey of 776 U.S. residents, divided approximately equally between teenagers and adults, smokers and nonsmokers, assessed public understanding of the illnesses caused by smoking. When respondents were asked what illnesses are caused by smoking, lung cancer was the only illness that could be identified by a clear majority of respondents. Roughly half mentioned emphysema. A much smaller percentage of respondents were able to mention any cardiovascular disease or any kind of cancer other than lung cancer. People also underestimated the death rate from lung cancer and overestimated survival duration. Only a minority realized that emphysema is incurable. Large portions of the sample said they knew only a little about the pain and suffering experienced by individuals with these illnesses. The results demonstrated that even though people recognize that smoking can lead to adverse health consequences, they do not have even a basic understanding of the nature and severity of these consequences.

Esophageal perforation is associated with high morbidity and mortality rates, particularly if not diagnosed and treated promptly. Despite the many advances in thoracic surgery, the management of patients with esophageal perforation remains controversial. We performed a retrospective clinical review of 36 patients, 15 women (41.7%) and 21 men (58.3%), treated at our hospital for esophageal perforation between 1989 and 2002. The mean age was 54.3 years (range 7-76 years). Iatrogenic causes were found in 63.9% of perforations, foreign body perforation in 16.7%, traumatic perforation in 13.9% and spontaneous rupture in 5.5%. Perforation occurred in the cervical esophagus in 12 cases, thoracic esophagus in 13 and abdominal esophagus in 11. Pain was the most common presenting symptom, occurring in 24 patients (66.7%). Dyspnea was noted in 14 patients (38.9%), fever in 12 (33.3%) and subcutaneous emphysema in 25 (69.4%). Management of esophageal perforation included primary closure in 19 (52.8%), resection in seven (19.4%) and non-surgical therapy in 10 (27.8%). The 30-day mortality was found to be 13.9%, and mean hospital stay was 24.4 days. In the surgically treated group the mortality rate was three of 26 patients (11.5%), and two of 10 patients (20%) in the conservatively managed group. Survival was significantly influenced by a delay of more than 24 h in the initiation of treatment. Primary closure within 24 h resulted in the most favorable outcome. Esophageal perforation is a life threatening condition, and any delay in diagnosis and therapy remains a major contributor to the attendant mortality.

Quality of life is an important indicator in assessing the burden of disease, especially for chronic conditions. The Health Utilities Index (HUI) is a recently developed system for measuring the overall health status and health-related quality of life (HRQL) of individuals, clinical groups, and general populations. Using the HUI (constructed based on eight attributes: vision, hearing, speech, mobility, dexterity, cognition, emotion, and pain/discomfort) to measure the HRQL for chronic disease patients and to detect possible associations between HUI system and various chronic conditions, this study provides information to improve the management of chronic diseases. This study is of interest to data analysts, policy makers, and public health practitioners involved in descriptive clinical studies, clinical trials, program evaluation, population health planning, and assessments. Based on the Canadian Community Health Survey (CCHS) for 2000-01, the HUI was used to measure the quality of life for individuals living with various chronic conditions (Alzheimer/other dementia, effects of stroke, urinary incontinence, arthritis/rheumatism, bowel disorder, cataracts, back problems, stomach/intestinal ulcers, emphysema/COPD, chronic bronchitis, epilepsy, heart disease, diabetes, migraine headaches, glaucoma, asthma, fibromyalgia, cancers, high blood pressure, multiple sclerosis, thyroid condition, and other remaining chronic diseases). Logistic Regression Model was employed to estimate the associations between the overall HUI scores and various chronic conditions. The HUI scores ranged from 0.00 (corresponding to a state close to death) to 1.00 (corresponding to perfect health); negative scores reflect health states considered worse than death. The mean HUI score by sex and age group indicated the typical quality of life for persons with various chronic conditions. Logistic Regression results showed a strong relationship between low HUI scores (< or = 0.5 and 0.06-1.0) and certain chronic conditions. Age- and sex-adjusted Odds Ratio (OR) and p values showed an effect among individuals diagnosed with each chronic disease on the overall HUI score. Results of this study showed that arthritis/rheumatism, heart disease, high blood pressure, cataracts, and diabetes had a severe impact on HRQL. Urinary incontinence, Alzheimer/other dementia, effects of stroke, cancers, thyroid condition, and back problems have a moderate impact. Food allergy, allergy other than food, asthma, migraine headaches, and other remaining chronic diseases have a relatively mild effect. It is concluded that major chronic diseases with significant health burden were associated with poor HRQL. The HUI scores facilitate the measurement and interpretation of results of health burden and the HRQL for individuals with chronic diseases and can be useful for development of strategies for the prevention and control of chronic diseases.
