Cap myopathy is pathologically characterized by cap structures comprising well-demarcated areas under the sarcolemma and containing deranged myofibrils and scattered Z-disks. Clinically it presents with slowly progressive muscle weakness, myopathic face, and frequent respiratory insufficiency. Four genes have been reported to be associated with the disease: TPM2, TPM3, ACTA1, and NEB. Here we describe that a patient presenting with mild limb weakness with facial affection showed cap structures on muscle pathology and carried a heterozygous TPM3 mutation.

Epithelioid sarcoma is a rare and highly malignant soft tissue neoplasm that most commonly occurs in the long bones. This uncommon tumor has a poor clinical outcome, and the modality of its treatment has not yet been fully established. The authors report an extremely rare presentation of epithelioid sarcoma in the cervical spine, along with its clinical progression, imaging, and pathology. The patient underwent three surgical procedures and adjuvant radiochemical management. He survived for 25 months with a good general condition and adapted well to his social activity. Systemic metastasis was not found, but the patient died of respiratory failure due to direct tracheal invasion of the tumor.

OBJECTIVEAcute interstitial pneumonia (AIP) is a rare lung interstitial disease in children. This study was conducted to understand the clinical features of the AIP in children.

METHODThe data of the three cases with AIP admitted to our hospital from March 2008 to November 2009 were reviewed. Of the 3 cases, 2 were male, one was female. Their age ranged from 1 year and 4 months to 10 years. The clinical manifestation, pulmonary function test and the high resolution computed tomography (HRCT) and pathology of the lung were studied retrospectively. Tissue specimens of the lung were obtained by video-assisted thoracoscopic biopsy. Viral etiologic examinations for the respiratory syncytial virus, adenovirus, influenza virus, parainfluenza viruses, EB virus, cytomegalovirus, enterovirus and herpes simplex virus were performed. The IgM antibody to Mycoplasma pneumoniae in the serum was also detected.

RESULTAll the 3 cases rapidly developed respiratory failure of unknown origin, none of these cases had failure of any other organs. All three cases had cough and dyspnea. No case had the rales and digital clubbing. The examinations for viruses, bacteria and Mycoplasma pneumoniae infection were all negative. No evidence for the diagnosis of connective tissue disease was obtained. The HRCT of the chest showed diffuse alveolar consolidation, air bronchogram and ground glass appearance in the bilateral lungs, and the traction-associated bronchiectasis in areas. All the three cases had the histological proof of diffuse alveolar damage by the biopsy. All the three cases were treated with CPAP and corticosteroid. Two cases were treated with corticosteroid in early stage of the disease, the condition of these cases were improved obviously. The third case was treated with high-dose steroid pulse therapy days, the condition of this case was improved slightly in a month. One year follow-up showed that case 1 and case 2 had no hypoxemia and the HRCT of the chest showed obvious improvement. The pulmonary function of case 2 had restrictive deficiency.

CONCLUSIONAIP has a rapidly progressive clinical course leading to respiratory failure. The HRCT of the chest showed alveolar consolidation and ground glass-like change. The pathology of the lung includes diffuse alveolar damage. The prognosis of the AIP in children may be improved by the treatment with respiratory assistance and corticosteroids.

OBJECTIVETo summarize the clinical characteristics, diagnosis, treatments and outcomes of perinatal autosomal recessive polycystic kidney disease.

METHODSThe clinical data of one case with infantile polycystic kidney disease diagnosed in perinatal stage and the reports of 11 cases seen in the past 15 years searched in Pubmed, OVID and Elsevier and CNKI, Wanfang database by using the polycystic kidney disease, infant, perinatal, autosomal recessive and case report as keyword were reviewed and analyzed.

RESULTSThe infant was characterized by huge kidneys, severe respiratory and renal compromise. The kidneys were symmetrically enlarged and highly echogenic by ultrasonographic examination and showed high-signal intensity on T2-weighted images by MRI. Histologic analysis showed pulmonary hypoplasia, numerous dilated and elongated tubular structures in the kidney and dilated intrahepatic biliary ducts. Among the 12 cases, 8 cases' presumptive diagnosis was made by prenatal ultrasound revealed enlarged kidneys and oligohydramnios. All cases suffered respiratory distress after birth, and 5 cases complicated pneumothorax. 6 cases died in neonatal stage because of respiratory failure.1 case died 2 m after birth because of renal failure. Five cases are alive and underwent dialysis, nephrectomy or renal transplant.

CONCLUSIONNewborn infants with perinatal autosomal recessive polycystic kidney disease often have poor outcome and died from respiratory and renal failure. Aggressive respiratory support and renal replacement therapy (including nephrectomy, dialysis and transplantation) may give these infants a favorable outcome.

We report a case of pulmonary fibrosis in a 32-year-old man, who had worked at a steel mill and who died of respiratory failure due to interstitial fibrosis despite vigorous treatment. He showed SLE-associated symptoms, such as pleural effusion, malar rashes, discoid rashes, arthritis, leukopenia, and positive antinuclear antibody and anti-histone antibody. However, he did not present anti-DNA antibody. A thoracoscopic lung biopsy showed interstitial fibrosis, chronic inflammation and a small non-caseating granuloma in lung tissues, which could be induced by external agents such as metals. The manganese concentration in the lung tissue was 4.64 microg/g compared to 0.42-0.7 microg/g in the controls. The levels of other metals, such as iron, nickel, cobalt and zinc in patient's lung tissue were higher than those in the controls. The patient was probably exposed to Si and various metal dusts, and the lung fibrosis was related to these exposures. Exposure to Si and metal dusts should be sought in the history of any patient with SLE, especially in a male with pulmonary signs, and if present, exposure should be stopped. In the meantime, steps should be taken to ensure that workers exposure to Si and metal dusts in all environments have adequate protection.

BACKGROUND: The diffuse infiltrative lung disease requires surgical lung biopsy for its final diagnosis. We evaluated the effect of surgical lung biopsy for final diagnosis of duffuse interstitial lung disease and compared video assisted thoracoscopic lung biopsy (TLB) with open lung biopsy (OLB). MATERIAL AND METHOD: We evaluated the patients who underwent surgical lung biopsy from March 2000 from December 2005, retrospectively. We divide to two groups (OLB and TLB group) and compared them. RESULT: There were 36 patients and cough was the most common pre- operative symptom. Surgery time, anesthetic time, hospital stay, duration of chest tube indwelling, specimen volume and the rate of post-operative complication were not significantly different between two groups. Histologic diagnosis was confirmed in all cases. There was one post-operative death who had suffered from respiratory failure since pre-operative period. CONCLUSION: Surgical lung biopsy is effective method in final diagnosis for diffuse infiltrative lung disease. Video assisted thoracoscopic lung biopsy is lesser invasive method than open lung biopsy and provide similar results, so it is basic diagnostic method of surgical lung biopsy.

PURPOSE: Since acute respiratory failure was one of the most fatal postoperative complications in lung cancer surgery, to know its incidence, and predisposing factors is very important. The purpose of this study was to determine the relationship between pre-operative interstitial pneumonia (IP) and post-operative acute respiratory failure. MATERIALS AND METHODS: A retrospective review of 672 patients with lung cancer who underwent curative pulmonary resection at the Hospital of Catholic University Medical College between 1997 and 2005 was undertaken. The patients were divided into two groups according to preexisting interstitial pneumonia or not by pre-operative chest HRCT or findings of pathologic papers. RESULTS: Twenty-eight patients (4.2%) developed post- operative respiratory failure and this proved to be fatal in 21 of these patients. We could find preoperative interstitial pathology in 53 patients (7.9%) among the 672 patients. The incidences of respiratory failure were 11.3% (6/53 cases) and 3.6% (22/619 cases) in IP group and non-IP group respectively. CONCLUSION: Interstitial pneumonia considered of one of the risk factors for developing postoperative acute respiratory failure in patients with lung cancer.
