BACKGROUND: we have evaluated the association of age, smoking, type of anesthesia, type of operation, duration of surgery, previous history of chronic pulmonary diseases with postoperative pulmonary complications and identified which parameter of preoperative spirometry was a predictor of postoperative pulmonary complications. METHOD: In 270 patients older than 60 years, the postoperative pulmonary complications were evaluated according to age, smoking, type of anesthesia, type of operation, duration of surgery, previous history of chronic pulmonary diseases and the parameters of preoperative spirometry were analyzed. RESULTS: The postoperative pulmonary complications rates were significant higher among patients older than 70 years, and among those with previous chronic pulmonary diseases or their smoking history. The pulmonary complications were increased among patients with general anesthesia or duration of surgery more than 2 hours. The pulmonary complications rates did not differ according to sex, type of operation. The patients with hypercarbia(PaCO2> 45mmHg) have more increased postoperative complications. The preoperative FEVl less than 1 liter, FVC, MMEFR & MVV less than 50% of predicted respectively were predictive of complications. CONCLUSION: Age 70, history of smoking,duration of operation more than 2 hours, general anesthesia, previous chronic pulmonary disease and hypercarbia (> or=45mmHg) on preoperative arterial blood gas analysis were predictivd of pulmonary complications. Among the parameters of spirometry, FEV1, FVC, MMEFR and MVV were indicator of predicting postoperative pulmonary complications.

Recent reports have indicated that a significant number of immune complex glomerulonephritis (GN) cases are associated with antineutrophilic cytoplasmic antibody (ANCA). However, most of the reported cases were associated with underlying primary glomerular diseases. When primary glomerular diseases were not found, immune deposits tended to be non-specific and the level of ANCA is usually borderline. We report here upon a case of life-threatening pulmonary-renal syndrome manifested simultaneously with immune complex GN and myeloperoxidase (MPO)-ANCA seropositivity. A 29- year-old man was admitted with pulmonary hemorrhage and rapidly progressing renal dysfunction. On admission, ANCA revealed perinuclear staining with a titer of 1:160. The MPO-ANCA level was 59 IU by ELISA. Other serologic markers including ANA, anti-DS-DNA and anti-GBM Ab were negative. Renal biopsy showed cellular crescents in eight of 18 glomeruli. Immunofluorescence staining showed strong granular deposits of C3, C1q, IgG and IgM in the capillary loop and the mesangium. Electron microscopy showed multifocal electron dense deposits scattered in the mesangium, paramesangium, and the subendothelial and subepithelial areas. The patient initially responded to steroid and cyclophosphamide. MPO-ANCA decreased to less than 10 IU. Twenty three days after hospital discharge, the patient was re-admitted urgently with fever, generalized papulonodular skin lesions, and a recurrence of massive pulmonary hemorrhage and renal dysfunction. He died from uncontrolled pulmonary hemorrhage and respiratory insufficiency. P-ANCA titer and MPO-ANCA level at the second admission were 1:320 and 82 U/ml respectively. Interestingly, relapse was shown to be triggered by varicella zoster infection.

3.Nutritional depletion in chronic obstructive pulmonary disease.
Acta Academiae Medicinae Sinicae 2004;26(5):595-599
Chronic obstructive pulmonary disease (COPD) is one of the major diseases worldwide. Nutritional depletion is a common problem in COPD patients and also an independant predictor of survival in these patients. Many data are helpful for determining nutritional depletion, including anthropometric measurement, laboratory markers, body composition analysis (fat-free mass and lean mass), and body weight. The mechanism of nutritional depletion in patients with COPD is still uncertain. It may be associated with energy/metabolism imbalance, tissue hypoxia, systemic inflammation, and leptin/orexin disorders. In patients with nutritional depletion, growth hormone and testosterone can be used for nutritional therapy in addition to nutrition supplementation.

BACKGROUND: To assess the outcome of pulmonary resection in the management of hemoptysis caused by benign inflammatory lung disease. MATERIAL AND METHOD: A longitudinal cohort study of 45 consecutive patients who were presented with hemoptysis and were treated with pulmonary resection from January 1995 to May 2004. The predictive preoperative risk factors of morbidity and recurrence of hemoptysis were analyzed. The mean age of the patients was 47.1 years. The mean follow-up was 35+/-34 months. RESULT: The overall hospital mortality rate was 4.4% (2/45). Postoperative complications occurred in 8 patients (18.6%). Complications were more common in patients who received blood transfusion than non-transfused patients (p=0.002). Patients with tuberculous destroyed lung disease had more amount of preoperative hemoptysis (p=0.002), more probability of transfusion (p=0.001), more probability of undergoing pneumonectomy (p=0.039) and more probability of postoperative morbidity. Patients of undergoing pneumonectomy had more probability of reoperation due to postoperative bleeding (p=0.047). Hemoptysis recurred in five patients but three had been subsided and two sustained during follow-up. A latter two patients had been prescribed with antituberculosis medication due to relapse of tuberculosis. CONCLUSION: A tuberculous destroyed lung disease has a higher rate of postoperative morbidity than other inflammatory lung diseases. A pneumonectomy in patients of inflammatory lung disease should be performed with great caution especially because of postoperative bleeding. Future study with longer and larger follow-up might show the reasons of recurrence of hemoptysis.

OBJECTIVEDiffuse lung disease comprises a large, heterogeneous group of pulmonary interstitial and parenchymal disease. It is therefore difficult to some extent to make etiologic diagnosis. Little information on clinical spectrum and diagnostic evaluation of pediatric diffuse lung disease is available in our country. The purpose of this study was to explore the causes of and diagnostic approach to diffuse lung disease in children.
METHODSTwenty-eight children with diffuse lung disease aged 2 months to 14 years were studied retrospectively. Their history, physical examination, radiographic findings, final diagnosis and diagnostic processes were reviewed.
RESULTSConfirmed diagnosis was established in 25 cases and suggestive diagnosis in 3 cases. Confirmed diagnoses included: mycoplasma pneumonia in 1 case, Chlamydia trachomatis pneumonia in 2 cases, Epstein-Barr virus pneumonia in 1, CMV pneumonia in 2, hematogenous disseminated pulmonary tuberculosis in 3, pulmonary cryptococcosis in 1, invasive pulmonary aspergillosis in 2, Staphylococcus aureus sepsis in 1, diffuse bronchiectasis in 2, idiopathic pulmonary hemosiderosis in 1, idiopathic pulmonary fibrosis in 1, extrinsic allergic alveolitis in 1, HIV-related lymphocytic interstitial pneumonitis in 1, Wegner's granulomatosis in 1, Langerhan's cell histiocytosis in 2, and lymphoma in 3. Suggestive diagnoses included Nocardia pneumonia in 1, Pneumocystis carinii pneumonia in 1, and juvenile rheumatoid arthritis-associated pulmonary fibrosis in 1. The diagnostic directions of 26 patients were conducted by radiographic features. In 17 of 26 cases, the diagnostic range was confined by history. The diagnosis of 14 cases was made by noninvasive tests including antibody detection, bacterial culture, those of 8 cases by examination of biopsy material, and those of 2 cases by autopsy.
CONCLUSIONSThe causes of pediatric diffuse lung disease included pulmonary infectious disease, idiopathic pulmonary disease and pulmonary lesion associated with systemic diseases. The diagnosis may be made by radiography, history, physical examination, noninvasive tests in most cases, while in some cases invasive procedures were necessary.

OBJECTIVETo investigate effect of lung protective ventilation on respiration and circulation in elderly patients receiving spinal operation performed in the prone position.
METHODSSixty patients undergoing elective spinal surgery were randomized control group [with VT of 10 mL/kg (PBW) and RR of 10-12 /min] and test group [with VT of 6 mL/kg +RMs+PEEP: 5 cmH(2)O (PBW) and RR of 12-18 /min]. Recruitment maneuver was performed once every 30 min. HR, MAP, P(peak), P(Plat), PaO(2)/FiO(2), SpO(2), PaCO(2), WBC, NEUT%, CRP, VAS, pulmonary complications risk score, and clinical pulmonary infection score were recorded before the operation, upon entry in the operation room, at 5 min before and 30 min, 1 h, and 3 h after changing into the prone position, and at 1 day and 3 days after the operation.
RESULTSPulmonary complications risk score, HR, MAP, WBC, NEUT%, and PaCO(2) were all comparable between the two groups (P>0.05). P(peak) and P(plat) of the test group were lower than those of the control group after entering the operation room and at 5 min before and 30 min, 1 h, and 3 h after changing into the prone position (P<0.05). Compared with those in the control group, the oxygenation index at 1 day after the operation was significantly higher and CRP and postoperative clinical pulmonary infection score at 1 day and 3 days after the operation were significantly lower in the test group (P<0.05).
CONCLUSIONSLung protective ventilation can reduce the risk of barotrauma, reduce lung inflammation, and improve postoperative oxygenation in elderly patients undergoing spinal surgery in the prone position without affecting intraoperative hemodynamics or causing CO(2) retention.

OBJECTIVETo improve the diagnostic accuracy of Wegener's granulomatosis (WG) with pulmonary involvement by analyzing the clinical data and chest radiographic features.
METHODSThe clinical data and chest radiographic features of 43 WG cases with pulmonary involvement were retrospectively analyzed.
RESULTSClinically, the patients frequently presented with multi-system involvement, with the incidence of pulmonary involvement of 72.8%. The patients with WG presented with such symptoms in the respiratory system as coughing, expectoration, hemoptysis, and dyspnea. The radiographic manifestations varied among the cases. Nodules and cavitations in the lungs were the signs most frequently found, and patchy infiltration and bronchial narrowing were also observed, which often led to misdiagnosis of WG as other pulmonary diseases.
CONCLUSIONWG often has multi-organ involvement, and the lung is one of the most commonly involved organs. The clinical symptoms and radiographic manifestations of WG have no specificity, and the disease can be easily misdiagnosed. Biopsy and ANCA assay can be important means for WG diagnosis.

We describe an unusual case of systemic lupus erythematosus with pulmonary manifestations presenting as hypoglycemia due to anti-insulin receptor antibodies. A 38-year-old female suffered an episode of unconsciousness and was admitted to hospital where her blood glucose was found to be 18 mg/dL. During the hypoglycemic episode, her serum insulin level was inappropriately high (2,207.1 pmol/L; normal range, 18 to 173) and C-peptide level was elevated (1.7 nmol/L; normal range, 0.37 to 1.47). Further blood tests revealed the presence of antinuclear antibodies, anti-double-stranded DNA antibodies, and anti-Ro/SSA, anti-La/SSB, anti-ribonucleoprotein, and anti-insulin receptor antibodies. A computed tomography scan of the abdomen, aimed at tumor localization, such as an insulinoma, instead revealed ground-glass opacities in both lower lungs, and no abnormal finding in the abdomen. For a definitive diagnosis of the lung lesion, video-associated thoracoscopic surgery was performed and histopathological findings showed a pattern of fibrotic non-specific interstitial pneumonia.

OBJECTIVETo investigate the risk factors for pleural lung disease (PLD) in children with juvenile idiopathic arthritis (JIA) and to provide a basis for the early diagnosis and timely treatment of this disease.
METHODSA total of 360 children with a confirmed diagnosis of JIA were enrolled, and their clinical data were retrospectively analyzed. All patients underwent a chest X-ray. The patients with PLD were assigned to PLD group, while those without PLD were assigned to non-PLD group. The clinical, imaging, and laboratory results of JIA patients with PLD were analyzed.
RESULTSAmong the 360 JIA patients, 43 (11.9%) had PLD, and 9 (21%) of them had respiratory symptoms. Chest X-ray findings mainly included interstitial pneumonitis (53.5%) and pleurisy and/or pleural effusion (38.1%). In the 43 cases of JIA-PLD, 4 (9.3%) had normal chest X-ray findings but abnormal chest CT findings. The incidence of PLD was relatively high in patients aged under 3 years and those aged 12 years or above. Children with systemic JIA had a relatively high incidence of PLD. Compared with the non-PLD group, the PLD group had a significantly higher incidence of anemia, elevated white blood cell (WBC) count and IgG levels in peripheral blood, and positive rheumatoid factors or antinuclear antibodies (P<0.05).
CONCLUSIONSAmong children with JIA, PLD is mostly seen in patients with systemic JIA or aged <3 years or ≥ 12 years, especially those with anemia, elevated WBC count and IgG levels, and positive rheumatoid factors or antinuclear antibodies. For JIA patients with PLD, interstitial pneumonitis is usually seen on chest X-ray or CT, but respiratory symptoms are rarely observed. Routine use of high-resolution chest CT is recommended for early diagnosis and timely treatment of PLD in children with JIA.

Glucocorticoids are effective for treating several respiratory diseases. However, they can cause hyperglycemia. This study determined the incidence and risk factors of steroidinduced diabetes mellitus (S-DM) in patients treated with glucocorticoid for respiratory diseases. A retrospective study examined patients with respiratory diseases treated with a prednisolone-equivalent glucocorticoid dose exceeding 20 mg/day for at least 4 weeks between January 2003 and December 2008. Patients whose initial random glucose level exceeded 200 mg/dL or who had pre-existing diabetes were excluded. S-DM was defined as a fasting glucose concentration exceeding 126 mg/dL or a random glucose concentration exceeding 200 mg/dL at least twice after beginning steroid treatment. A total of 231 patients with respiratory diseases met the inclusion criteria. Their median age was 55 yr, and 139 were female. The median cumulative prednisolone-equivalent glucocorticoid dose was 4,965 mg, and the median duration of steroid treatment was 193 days. S-DM was diagnosed in 34 (14.7%) of 231 patients. Multivariate logistic regression identified older age (odds ratio 1.05, 95% confidence interval 1.02-1.09) as a risk factor for S-DM. S-DM is frequent among patients with respiratory diseases treated with glucocorticoid. Clinicians should be aware of the possibility of S-DM, especially among elderly patients.
