RESUMO

Case 1: 83 years old man. For left upper lobe lungs squamous cell carcinoma infiltrating left main pulmonary artery. After 2 courses went of carboplatin(CBDCA)(AUC: 6)+weekly nab-paclitaxel(nab-PTX)(AUC: 6)+, left upper lobectomy and ND2 lymph nodes dissection. Tumor disappeared in pathology and diagnosed of Ef. 3. Case 2: 81 years old man. Right upper lobe lungs squamous cell carcinoma in #4R lymph node metastasis with the superior vena cava invasion. After 2 courses went of CBDCA(AUC: 6)+weekly nab-PTX(100mg/m2), left upper lobectomy and ND2 lymph nodes dissection. Tumor disappeared in pathology and diagnosed of Ef. 3. Nab-PTX may be considered a preoperative chemotherapeutic agent of choice for squamous cell carcinoma.

RESUMO

PURPOSE: Elevated plasma A-type natriuretic peptide (ANP) levels in sepsis cause fluid transfer into extravascular spaces. We investigated the changes in ANP concentrations and natriuretic peptide receptor (NPR) expression induced by thiorphan, a neutral endopeptidase (NEP) inhibitor, in a rat model of sepsis. METHODS: Fifteen male rats were divided into three groups: a control group (n = 5), a lipopolysaccharide (LPS) group (n = 5), and an LPS-thiorphan group (n = 5). We measured ANP concentrations in the plasma and lung, and NPR mRNA expression in the lung 4 h after administering LPS, and compared the values with those in the control group. RESULTS: Plasma and lung ANP levels in the LPS group were significantly higher than those in the control group (P < 0.05), but were significantly decreased by thiorphan administration (P < 0.05). NPR-A mRNA levels did not differ significantly among the groups. NPR-C mRNA levels in the LPS-thiorphan group were significantly higher than those in the other groups (P < 0.05). CONCLUSIONS: Elevated ANP levels were decreased by thiorphan administration, which increased NPR-C mRNA levels in the lung. Thus, thiorphan might be effective for reducing elevated ANP levels in sepsis.

RESUMO

OBJECTIVE: The objective of the present study was to perform longitudinal objective evaluations of recovery of exercise capacity based on expired gas analysis during exercise testing up to 1 year after pulmonary resection. METHODS: The study included 18 patients who underwent lobectomy. Expired gas analysis during exercise testing was conducted 1 week before surgery and 2 weeks, 1 month, 3 months, 6 months, and 1 year after surgery. The parameters studied included maximum exercise capacity based on expired gas analysis during exercise testing (maximum oxygen uptake per minute per square meter of body surface area) and assessment of moderate exercise capacity (anaerobic threshold per square meter of body surface area). The changes in postoperative data relative to the preoperative values (baseline) were assessed, including the percent changes from baseline data, which were arbitrarily given a value of 100. RESULTS: Maximum oxygen uptake per minute per square meter of body surface area decreased significantly to 78.6% +/- 14.2% of the baseline value at 2 weeks after surgery and was 80.3% +/- 12.7%, 90.9% +/- 15.9%, 90% +/- 19.7%, and 97% +/- 4.8% of the baseline value at 1, 3, and 6 months, and 1 year, respectively. Anaerobic threshold per square meter of body surface area reached 91.1% +/- 17.5% of the baseline value even 2 weeks after surgery and was 87.1% +/- 17.3%, 97.5% +/- 28.0%, 84.3% +/- 13.2%, and 104% +/- 16.2% of the baseline value at 1, 3, and 6 months, and 1 year, respectively. CONCLUSION: The extent of recovery of exercise capacity at 1 year after surgery was approximately 95%. Furthermore, the anaerobic threshold per square meter of body surface area was restored to the preoperative level by 1 year after surgery.

RESUMO

PURPOSE: We previously found a potential predictive value in a retrospective analysis of spirometry and an expired gas analysis during the exercise. We sought to reduce postoperative cardiopulmonary complications by selecting lung tumor resection procedures based on a combination of specific preoperative cardiopulmonary function test results. METHODS: Out of the 53 patients requiring a lung tumor resection, five preoperative parameters (forced expiratory volume in 1 s for intact-side, maximal oxygen uptake, ejection fraction, occluded pulmonary artery pressure, and occluded total pulmonary vascular resistant index) were used to assign patients to one of five risk categories in order to select the optimal pulmonary resection procedure. The patients were later grouped according to their postoperative course to test the value of this procedure selection method. RESULTS: No patient died or developed severe complications after surgery. Five patients had mild complications, while 46 had a good postoperative course; the 13 deaths, in the cancer cases, included 11 from primary or metastatic cancer and 2 from other causes. The overall five-year survival was 61.4%. CONCLUSION: This method for determining a pulmonary resection procedure avoided postoperative deaths and severe cardiopulmonary complications, while achieving a good outcome.

RESUMO

We report a case of pancreatic injury, caused by a stab wound, in which ductal injury and wound depth were clearly identified by intraoperative ultrasonography. A 65-year-old woman was emergently admitted to our hospital after stabbing herself in the abdomen in a suicide attempt. Preoperative computed tomography (CT) and laboratory examination revealed liver and pancreatic injury with massive abdominal bleeding and free air. Operative findings included injuries of the stomach, small bowel, colon, liver, and pancreas. The pancreatic lacerations were 1 cm in length, in the body. Intraoperative ultrasonography enabled the diagnosis of a lacerated main pancreatic duct with no damage to the major vessels posterior to the pancreas. Distal pancreatectomy; simple repairs of the liver, small bowel, and stomach; exteriorization of the injured colon; cholecystostomy; gastrostomy; and jejunostomy were performed. The patient recovered and was transferred to a psychiatric hospital 87 days after surgery. In this patient, intraoperative ultrasonography was successfully used to identify the degree of injury to the pancreatic duct, as well as the depth of the stab wound. In conclusion, intraoperative ultrasonography should be routinely performed to detect main pancreatic duct injury in penetrating pancreatic trauma.

RESUMO

A 33-year-old woman being treated for rheumatoid arthritis was referred to our hospital for investigation of a mediastinal mass. A chest computed tomography scan showed an anterior mediastinal mass, 8.5 x 7.0 cm in size, with a cystic lesion and calcification. These findings were suggestive of either a noninvasive thymoma or a mature teratoma. Therefore, we performed tumor resection and thymectomy. Histologically, the tumor consisted of diffuse deposits of massive eosinophilic amorphous material. The tumor was stained red-orange by Congo red, and the staining disappeared following potassium permanganate digestion. Based on these findings, a diagnosis of reactive amyloidosis of the amyloid A-protein-derived type was made. Amyloidosis in the mediastinum has rarely been described.

RESUMO

We present a case of a 78-year-old man with a synchronous double cancer of the lung and Vater's papilla. A pancreaticoduodenectomy was performed for Vater's papilla cancer and a partial lung resection for lung cancer. The pathological diagnosis of the tumors was a well differentiated tubular adenocarcinoma and well differentiated bronchioloalveolar carcinoma, respectively. Although most cases of synchronous double cancers involve lung and gastric cancers, a combination of lung and Vater's papilla is extremely rare. This patient is still alive with no recurrence for 5 years after the last operation.

RESUMO

A giant bulla of the lung is suggested as a risk factor for lung cancer. Here we report a case with lung cancer in a giant bulla, which showed rapid progression. A 57-year-old man, who had a history of heavy smoking, was admitted to our hospital due to hemoptysis. A chest X-ray revealed a giant bulla with a ground glass shadow and a high fluid level in the right upper lung. Sputum cytology was negative for malignant cells. A chest X-ray a month later showed increases of the size of the radio-opaque shadow and of the air-fluid retention, suggesting pulmonary hemorrhage from the giant bulla. Limited resection or lobectomy was indicated, but pneumonectomy was performed due to the severe air-leak. Macroscopically, a multiple nodular tumor arose from the bulla wall, which might be related to blood flow and necrotic tissue. The postoperative pathological diagnosis was papillary adenocarcinoma. Unfortunately, the patient developed a recurrence of carcinoma in the pleuroperitoneal cavity and died at 2.5 months after the operation. Based on this report and review of other cases in the literature, we should keep in mind the rapid progression of lung cancer in association with an emphysematous bulla.
