RESUMO
INTRODUCTION: A paradoxical reaction during antituberculosis treatment is defined as the worsening of pre-existing tuberculosis lesions or the appearance of a new tuberculosis lesion in patients whose clinical symptoms improved with antituberculosis treatment. The median onset time to the development of a paradoxical response has been reported to be about 60 days after the start of treatment. We report the case of a patient with a paradoxical reaction presenting as a psoas abscess after nine months of antituberculosis treatment. To the best of our knowledge, this manifestation has not previously been reported. CASE PRESENTATION: A 23-year-old Japanese man presented to our hospital with lower abdominal pain. Computed tomography showed that he had mediastinal and abdominal para-aortic lymph node swellings. Fluorine-18 fluorodeoxyglucose positron emission tomography showed hot spots in these lymph nodes and in his right cervical lymph node, suggesting a lymphoma. The examination of an abdominal lymph node biopsy specimen showed lymph node tuberculosis, so antituberculosis treatment was started. However, after nine months of treatment, he experienced right flank pain. Abdominal computed tomography showed a right psoas abscess and abdominal para-aortic lymph node swelling. The abscess was treated by percutaneous drainage. After repeated drainage, the psoas abscess subsided and disappeared. The purulent fluid yielded no microorganisms, suggesting a paradoxical reaction. CONCLUSION: Attention should be paid to paradoxical reactions occurring during antituberculosis treatment for systemic lymph node tuberculosis.
RESUMO
A 15-year-old asymptomatic girl had an abnormal shadow pointed out on a chest roentgenogram during a school medical health check. Her chest X-ray films showed a mass in the left pulmonary hilum that had increased in size during the past 2 years. Chest computed tomography (CT) showed a mass, which showed slight accumulation on FDG-PET in the left pulmonary hilum. Left lower lobectomy was performed for diagnosis, and the histopathological diagnosis was hyaline vascular-type Castleman disease. We report a case of hyaline vascular-type Castleman disease in the right pulmonary hilum which increased quite rapidly.

A 57-year-old woman in whom pulmonary arteriovenous malformation (PAVM) associated with hereditary hemorrhagic telangiectasia (HHT) had been diagnosed after a chest X-ray film showed an abnormal shadow at the age of 39. After diagnosis, she suffered two ischemic brain attacks, presumably caused by PAVM. She was admitted to our hospital for evaluation and treatment of PAVM on February 9, 2008. We confirmed two PAVMs in right S(3)a and left S(9)a by chest CT scan and angiography. In addition, abdominal CT revealed hepatic arteriovenous malformation (HAVM). HAVM were thought to increase venous return to the right heart, (which might cause pulmonary hypertension after the embolization of PAVMs), leading to right heart failure. In order to prevent neurological events in future, we performed an embolization of PAVM with individual coils at monthly intervals. Six months after the last embolization treatment, she showed no symptoms of right heart failure and the size of PAVMs decreased. It is considered important for a patient with PAVM associated with HHT to undergo a thorough examination for arteriovenous malformation in other organs, before coil embolization.

A 58-year-old man was admitted our hospital. Chest computed tomography (CT) showed a nodular opacity in the left upper lobe and a swollen lymph node in the left hilar region. 18-fluorodeoxyglucose positron emission tomography (FDG-PET) showed abnormal uptakes in the same field. Since thoracoscopic lung biopsy revealed that the tumor was poorly differentiated adenocarcinoma, a left upper lobectomy and lymph node dissection were performed. Histological findings showed numerous spindle cells, thus it was diagnosed as pleomorphic carcinoma, pT2N1M0. After three months, a FDG-PET was performed, which detected a tiny lesion in the spleen. However an abdominal CT scan and ultrasonography (US) performed in the same period showed no abnormal findings. After about 2 months, a solitary low density area (5.0 cm) was seen in the spleen on an abdominal CT scan. We performed splenectomy under a diagnosis of a solitary splenic metastasis of the lung cancer. Pathological confirmation was obtained. Our findings demonstrated that whole-body scanning by FDG-PET was able to detect a rare postoperative splenic recurrence earlier than CT or US scan.

A 20-year-old woman with no history of pulmonary disease had no symptom and her chest CT scans demonstrated adhesive small multiple nodules in the bronchial lung biopsy specimen showed epithelioid cell granuloma containing Langhans giant cells, therefore she was diagnosed as pulmonary mycobacteriosis caused by M. szulgai. This is the youngest case of this rare condition occurring in a healthy subject without underlying pulmonary diseases.

Gefitinib (ZD1839), a small-molecule epidermal growth factor receptor tyrosine kinase inhibitor, is an anticancer agent for patients with non-small cell lung carcinoma. Recently, however, as a result of accumulating evidence, it has been recognized that gefitinib can give rise to lethal lung toxicity. The authors report a case of interstitial lung disease (ILD) induced by gefitinib, which improved promptly following cessation of the administration of the agent. Clinical signs suggesting a good prognosis were noted, namely, findings similar to acute eosinophilic pneumonia on CT and a disassociation in the elevation of specific serum markers of ILD. At the time of onset of ILD, serum concentrations of surfactant protein (SP)-A and SP-D were significantly increased, whereas that of KL-6 was not increased. A previous study of three cases of lethal lung toxicity resulting from gefitinib administration revealed a significant and almost equal increase in KL-6, SP-A and SP-D. These results suggest that SP-A and SP-D may be indicators of gefitinib-induced ILD and that KL-6 is a predictor of outcome. Using a combination of these markers may help to establish a differential prognosis in patients with gefitinib-induced ILD.

BACKGROUND: T helper type 1 (Th1) responses have been implicated in the protective immunity, pathophysiology and development of tuberculosis. However, it is still unclear which molecule(s) reflect disease activity in patients with tuberculosis. METHODS: By specific enzyme immunoassays, circulating interferon-gamma. (IFN-gamma), interleukin-12 (IL-12), IL-18 and osteopontin (OPN) were measured in 47 patients with pulmonary tuberculosis and 7 patients with miliary tuberculosis before anti-tuberculosis therapy, and also measured in 19 patients with tuberculosis before and after anti-tuberculosis therapy. RESULTS: Circulating IFN-gamma, IL-18 and OPN levels were significantly higher in patients with pulmonary tuberculosis than in healthy controls, while there was no significant difference in levels of circulating IL-12 between tuberculosis patients and controls. Circulating IFN-gamma, IL-12, IL-18 and OPN paralleled the extent of lung lesions, and circulating IFN-gamma, IL-18 and OPN paralleled the magnitude of fever in patients with pulmonary tuberculosis. Patients with miliary tuberculosis had extremely high levels of circulating OPN, IFN-gamma and IL-18. Circulating IL-18 and OPN were significantly decreased with anti-tuberculosis therapy, whereas circulating IL-12 and IFN-gamma were not. CONCLUSIONS: Among Th1 response associated molecules, circulating levels of IL-18 and OPN, but not IFN-gamma or IL-12, reflect disease activity in patients with tuberculosis.

Gefitinib, a selective epidermal growth factor receptor tyrosine kinase inhibitor, is an effective treatment for patients with non-small cell lung cancer (NSCLC). Some investigators have recently reported several patients complicated by acute lung injury after the initiation of gefitinib administration. In this report, we investigated the efficacy and adverse events during treatment with gefitinib. The subjects of this study were all of the 110 patients with NSCLC who were treated in our hospital and its eight branch hospitals. Patients received gefitinib at a dose of 250 mg once daily. The response rate was 30%. The frequently reported adverse events were skin disorders, gastrointestinal disturbances, liver dysfunction and acute lung injury. Five of the 12 patients who were considered to have suffered acute lung injury died of progressive respiratory failure. Of the nine patients who had pulmonary fibrosis before use of gefitinib, five developed acute lung injury during the treatment. Sera from three of the 12 patients were evaluated and all three showed increases of surfactant protein (SP)-A, SP-D and KL-6. We conclude that gefitinib was clinically useful. However, several patients suffered acute lung injury which could have been caused by gefitinib. A detection system including SP-A, SP-D and KL-6 as prime candidates as markers should be established as promptly as possible. Clinicians should be aware that treatment of NSCLC with gefitinib involves the risk of acute lung injury and therefore careful consideration should be given before deciding whether or not gefitinib is indicated for treatment. Further study is necessary to elucidate the mechanism of acute lung injury by gefitinib.

Clara cell 10-kD protein (CC10) exhibits potent antiinflammatory properties. G38A polymorphism was found in the CC10 gene. We investigated the genetic influence of the allele on the development of sarcoidosis using case control analysis in a Japanese population (265 sarcoidosis cases and 258 control subjects). The A allele frequency in sarcoidosis cases (45.1%) was significantly higher than healthy control subjects (34.9%, p = 0.0002). According to outcomes, we divided 223 patients with follow-up periods of 3 years or more into two subgroups (55 progressive and 168 regressive disease). The A allele frequency in patients with progressive disease was significantly higher than control subjects (odds ratio = 4.55; 95% confidence interval, 2.97-6.97; p < 0.0001), whereas that of regressive disease was not. The A/A genotypes had significantly lower bronchoalveolar lavage fluid CC10 levels than the G/G (nonsmokers, p = 0.0054, and smokers, p = 0.0045) and G/A genotypes (nonsmokers, p = 0.0022, and smokers, p = 0.0402). The reporter gene assay showed significantly lower reporter activities in the presence of interferon-gamma for the 38A construct than the 38G construct (p = 0.0177). The G38A polymorphism in the CC10 gene may influence protein expression and be associated with the development of progressive sarcoidosis.

A 30-year-old woman presented with multiple nodular shadows which enclosed a cavity on a chest radiograph. Chest computed tomographic (CT) images showed mediastinal lymphadenopathy, and multiple nodular opacities enclosing a cavity. Histopathological findings of biopsy specimens from the lung and mediastinal lymph nodes revealed noncaseating epithelioid cell granulomas without any evidence of Mycobacterium or fungal growth. The lesion in the lung included granulomatous vasculitis. Even without corticosteroid or any other therapy, the lung lesions resolved and the cavity disappeared. We report a case of sarcoidosis with primary acute cavitation.
