A 4-month-old male Siberian Husky dog had a history of coughing, high fever and anorexia. Thoracic radiographs revealed increased radiographic density in the cranial and middle lobes of the right lung, with pleural effusion. Cytological examination of the pleural fluid suggested carcinomatous pleuritis. Right-side thoracotomy and resection of the cranial and middle lobes were performed. Histopathological examination of the resected tissue revealed an anaplastic large cell carcinoma. The tumour cells were positive for neuron specific enolase and also contained neuroendocrine granules. A particularly unusual feature of this case of pulmonary neuroendocrine carcinoma was the young age of the affected animal.

A 4-month-old sexually intact blue-neck ostrich was examined because of chronic respiratory tract disease and poor performance. The bird was coughing and dyspneic on physical examination. Thoracic radiographs were consistent with air sacculitis. Bronchoscopy was used to view and to biopsy plaques within the bronchus and lower airways. Aspergillus spp was identified in culture and in biopsy specimens examined microscopically. Aspergillosis was confirmed on postmortem examination. Bronchoscopy may aid in the early diagnosis and treatment of this disease.

Studies of respiratory questionnaire efficacy have emphasized reliability of responses; few have validated symptom response with objective measures of pulmonary function. To determine whether respiratory symptoms are associated with diminished pulmonary function, symptoms reported on the American Thoracic Society (ATS-DLD-78A) questionnaire were correlated cross-sectionally with measured spirometric volumes in 816 asbestos-exposed workers. Cough, phlegm, wheeze, and dyspnea were inversely related to pulmonary function. Cough, phlegm, and chronic bronchitis were associated with a 2 to 8% reduction (p < 0.001) in predicted values for forced vital capacity (FVC) and forced expiratory volume (FEV1); wheeze and dyspnea were clinically more significant, with an 11 to 17% reduction (p < 0.001). Wheeze, dyspnea, and roentgenographic fibrosis were all significant independent predictors of risk for restrictive impairment. These results support the validity of the ATS questionnaire as an epidemiologic tool and emphasize the importance of clinical history in assessing respiratory status.

Chronic granulomatous disease of childhood is an inheritable disorder of phagocytic cell respiratory burst resulting in recurrent, life-threatening, catalase-positive infections. The lung is the most common site of infection, and pulmonary disease is the primary cause of death in greater than 50% of children with chronic granulomatous disease. Still, the role of surgery in management of this disease remains undefined. Between 1974 and 1990, 19 patients with chronic granulomatous disease required 31 thoracic interventions at our institution. Patients ranged in age from 2.5 to 27 years (mean age, 15 years). Seventeen of 19 patients (89%) had had previous pulmonary infections. Patients presented as toxic (temperature > 38.5 degrees C, chest pain, and cough) in 22 instances before the 31 procedures. Aggressive surgical intervention for diagnosis and extirpation of localized infections was undertaken with lobectomy/pneumonectomy with or without other procedures (5), bisegmentectomy (2), segmentectomy with or without other procedures (5), or wedge with or without other procedures (13). In five instances, an empyema was drained; a chest tube for a sterile collection was placed in one instance. There was one intraoperative death, and 3 patients died 22 to 600 days postoperatively with overwhelming sepsis. The mean hospitalization was 101 days (range, 24 to 600 days). Wound complications occurred in 5 patients, requiring 17 separate anesthetic debridements. A change in therapy was dictated by the results of the procedure in 23 of 31 instances (74%). Thoracic surgeons must be aware of this rare cause of immunosuppression in these children and, due to the unusual nature of the pulmonary infections, should follow an aggressive approach in their diagnosis and management.

The role of rapidly growing mycobacteria (RGM) as pulmonary pathogens has been unclear. We identified 154 cases of lung disease caused by RGM using the microbiologic and radiographic criteria of the American Thoracic Society (ATS) and availability of the causative organism for study. More than one third of patients had positive lung biopsy cultures. Patients were predominantly white (83%), female (65%) nonsmokers (66%), and they had prolonged periods from onset of symptoms to diagnosis of their disease. Cough was an almost universal presenting symptom, whereas constitutional symptoms became more important with progression of disease. Upper lobe infiltrates were most common (88%), with 77% of patients developing bilateral disease. Cavitation was present in only 16% of the patients. Specific underlying diseases were infrequent, but they included previously treated mycobacterial disease (18%), coexistent Mycobacterium avium complex (8%), cystic fibrosis (6%), and gastroesophageal disorders with chronic vomiting (6%). The majority of isolates (82%) were M. abscessus (formerly M. chelonae subsp. abscessus). Effective treatment for M. fortuitum long disease was accomplished with drug therapy, whereas surgical resection of localized disease was the only effective long-term therapy for M. abscessus. Although the disease was generally slowly progressive, 21 of 154 (14%) patients died as a consequence of progressive RGM lung disease and respiratory failure. RGM should be recognized as a cause of chronic mycobacterial lung disease, and respiratory isolates should be assessed carefully.

We have determined if thoracic extradural block before surgical incision for thoracotomy produces pre-emptive analgesia. Using a double-blind, placebo-controlled, crossover design, 45 patients (ASA II-III) undergoing posterolateral thoracotomy for lung resection were randomized to one of three groups: group 1 received 0.5% bupivacaine and adrenaline 1/200,000 (B+E) 8 ml through a thoracic extradural catheter (tip T3-T5) 30 min before skin incision and saline 8 ml 15 min after skin incision; group 2 received saline 8 ml extradurally before incision and B+E 8 ml after incision; group 3 received saline 8 ml extradurally before and after incision. General anaesthesia was induced and maintained with propofol, alfentanil and atracurium. The alfentanil infusion was stopped before chest closure and fentanyl 50 micrograms in saline 10 ml was given extradurally. Patient-controlled extradural analgesia (PCEA) was commenced with 0.125% bupivacaine, adrenaline 1/400,000 and fentanyl 6 micrograms ml-1 (continuous rate of 2 ml h-1 and supplementary doses of 0.5 ml per 6 min). Visual analogue scale (VAS) scores (recorded at rest, on mobilization and after cough), verbal rating scale (VRS) (recorded at rest), number of successful PCEA demands and complications were measured during the first 48 h after operation. There was no significant difference between groups, either in PCEA requirements (P > 0.21) or in VAS scores (either at rest, during mobilization of the ipsilateral arm of surgery or after cough). No significant differences between groups were found in the VRS. Thoracic extradural block with bupivacaine did not produce an early preemptive effect after thoracotomy.

Case 1: A 26-year-old primipara, underwent emergency cesarean section because of premature rupture of membrane and breech presentation in her 36th week of gestation. She had no history of asthma, but physical examination revealed atopic dermatitis in the neck and the arms. Case 2: A 21-year-old woman underwent removal of ovarian cyst. She had a history of asthma in her childhood. On physical examination there was no abnormal findings. For both cases spinal anesthesia was uneventfully induced using 2 and 3 ml of 0.4% tetracaine in 10% dextrose respectively. Sensory loss to cold extended to T3 in both cases. Immediately after the anesthesia reached two level, the first patient began to cough and the second patient complained of difficulty in breathing, and then both became dyspneic in 10-15 minutes thereafter. Wheezing rhonchi was audible in both cases. Both patients recovered fully with antiasthmatic therapy. There was no shock, nor change of the skin and the mucosa. The baby also had no problem postoperatively. Skin reaction to intradermal injection of 0.025 ml of 0.4-0.00004% tetracaine in normal saline was tested on two patients and on eleven volunteers. At higher concentrations it resulted in positive in the patients and all the volunteers, and at lower concentrations it resulted in positive in case 2 and under-positive in case 1 and three volunteers having histories of allergic disease. Skin testing alone does not offer any diagnostic of tetracaine allergy, because tetracaine might be a chemical irritant. Thoracic adrenergic nerve blockade due to spinal anesthesia might trigger asthmatic attack by influencing the cholinergic ganglia of the lung and/or pulmonary blood flow.

Interstitial pneumonia is the most common disease caused by infection from cytomegalovirus (CMV) in immunodepressed patients, whereas it is a rare complication in immunocompetent patients. With reference to the second group of patients, little literature has been produced as for the therapy to choose when symptoms are serious. We report the case of immunocompetent adolescent with CMV pneumonitis who responded dramatically to therapy with ganciclovir. For a week B. M., a 15-year-old girl, has been showing fever, cough and boring pain at her left thoracic base. When hospitalized, the girl was suffering and dyspneic, cardio-thoracic conditions were bad. Spleen and liver were palpable two fingers far form costal arch. Hematochemical tests showed an increase in phlogosis and transaminase value. Thoracic X-ray was negative, as well as cultures. Among the serological tests high response of anti-CMV IgM was remarkable. Virological blood test confirmed active CMV infection. On the fifth day, a thoracic radiography showed widespread interstitial infiltrates. Treatment with ganciclovir--i.v. 6 mg/kg/day, twice a day for twelve days--has been then adopted. After two day treatment, the girls was apyretic and eupneic. After ten day treatment, thoracic radiography was negative and a great decrease in CMV antigenic response was given by blood tests. No side effect were observed. According to our experience we can say that treatment with ganciclovir may positively shorten the course of pneumonia caused by CMV in immunocompetent patients.

The allergens of domestic pets such as cats, dogs and birds, have been known to sensitive predisposed individuals. In Singapore, approximately 25% to 35% of our atopic populations are sensitised to cat, dog or bird feather allergens. It is not known, however, if the presence of such domestic pets would translate to higher rates of sensitisation, or more importantly, give rise to increased respiratory symptoms. This study evaluated the association between the presence of domestic pets at home and the prevalence of respiratory symptoms among asthmatic children in Singapore. The parents of 1517 doctor-diagnosed asthmatic children were interviewed using the American Thoracic Society-Division of Lung Diseases respiratory questionnaire. More than 20% were found to have domestic pets (cats, dogs or birds) at home. Of these, those with exposure to passive smoke in the home were excluded. A total of 188 current pet owners (cats, dogs and birds) were demographically-matched for sex, race and socio-economic status (type of housing) to those without pets, past or current. Compared to those without pets, asthmatic children with pets at home had a higher prevalence of coughing with cold [relative risk (RR) 1.30; 95% confidence interval (CI) 1.01 to 1.69]; wheezing with cold (RR 1.42; CI 1.07 to 1.90), wheezing with shortness of breath (RR 1.33; CI 1.00 to 1.82), exercise-induced wheezing (RR 1.68; CI 1.10 to 2.56); and increased phlegm production or congestion with cold (RR 1.38; CI 1.00 to 1.91). This study suggests that the presence of domestic pets increases the prevalence of respiratory symptoms in asthmatic children. Those with predisposition to these allergens should avoid having these pets in the home or take specific precautions in avoiding their allergens.

Thoracic epidural anaesthesia (TEA) faces growing interest as an adjuvant anaesthetic and postoperative analgesic regimen. The procedure allows a specific blockade of nociceptive reflex arches and may exert beneficial effects on stress-induced alterations of organ function. Myocardial blood flow to areas at risk is improved, and paradoxical reactions of atherosclerotic coronary arteries after sympathetic stimulation are suppressed. After cardiac surgery, TEA improved postoperative recovery and resulted in better haemodynamic stability and allowed earlier extubation. During vascular surgery, the graft occlusion rate was significantly decreased. The improved pulmonary function after TEA is due to superior pain relief which allows the patients to breathe and cough sufficiently. After upper abdominal surgery, TEA leads to improved recovery of gastrointestinal function which reduces the risk of bacterial translocation. Although lumbar epidural anaesthesia is preferred by many anaesthesiologists as there is no risk of traumatizing the spinal cord, many positive effects are forgone. With insufficient rostral spread of a lumbar epidural block above the fifth thoracic level, cardiac complications can occur due to reflex activation of sympathetic outflow in unblocked thoracic regions. When the contraindications are carefully observed, TEA can be safely performed in most patients.
