ABSTRACT

Acute fibrinous and organizing pneumonia (AFOP) is rare in patients with systemic lupus erythematosus (SLE). We herein report a case of AFOP with SLE and hemophagocytic syndrome. Early-phase high-resolution computed tomography showed a fine granular lung pattern. A pathological examination revealed AFOP. An immunohistological examination revealed numerous CD163+ and fewer CD68+ macrophages present in the lung tissue and in alveolar spaces as well, including fibrin balls, the interstitium, and bronchial walls. Pneumonia and thrombocytopenia worsened during high-dose steroid therapy, plasma exchange, and intravenous immunoglobulin administration. The addition of intravenous cyclophosphamide successfully ameliorated the symptoms and radiographic lesions. Therefore, this therapy may be useful for treating severe AFOP.

ABSTRACT

[Objective] To determine whether three sputum examinations with fluorescent staining are necessary to diag- nose tuberculosis (TB) in our hospital. [Patients] From April 2005 to December 2012, 379 TB patients were admitted and received anti-TB therapy in our hospital. [Methods] A retrospective study was conducted to assess the positivity rates of sputum smears based on three exami- nations. The positivity rate of first sputum smear and the cumulative smear-positive rates in the second and third were determined. Then, we also determined difference of positivity rates in sputum properties, sampling procedures and cavity formation. [Results] Of the 379 patients who met the screening criteria, 300 tested positive based on the first sputum smear (79.2%). The positivity rate of the first sputum smears was higher in the purulent sputum group than in the mucous sputum group (91.2% vs. 72.3%). Cavity formation, and sputum extraction procedures were not related to the positivity rate of the first sputum smears. In the mucous sputum group, the cumulative smear-positive rate in the second test significantly rose, but did not rise in the third test. [Conclusions] Three sputum smear examinations were necessary in patients who submitted mucous sputum samples. It is important to get purulent sputum.

ABSTRACT

PURPOSE: We report an outbreak of 64 cases of tuberculosis (TB) that spread in a welfare facility for elderly individuals. OBJECTIVE AND METHODS: First, 64 TB patients who had contact with the source patient were screened at our hospital. We examined the time course up to the discovery of symptoms and analyzed the results for variable numbers of tandem repeats (VNTR) and the drug susceptibility tests. Second, we performed chest computed tomography to examine lesions due to a previous TB infection. RESULT: The source patient had recurrent aspiration pneumonia. The delay in doctor consultation was considered day 0, and the delay of diagnosis was 267 days. On examining the contacts, we found that 29 patients had TB while 35 had a latent TB infection. Results of the VNTR and the drug susceptibility tests showed that all the patients who developed TB had the same pattern as that of the source patient. Chest computed tomography showed lesions due to a previous TB infection in 8 patients. CONCLUSION: Based on the results of the VNTR and drug susceptibility tests, we concluded that the outbreak was due to an exogenous infection from the same source. All 8 patients who showed lesions due to a previous TB infection were aged > 81 years, and TB in these patients was found to be due to exogenous re-infection.

ABSTRACT

A 31-year-old woman developed a constant cough during the 8th week of pregnancy and was diagnosed with bronchial asthma. She was prescribed prednisolone and inhaled corticosteroids. At 28 weeks of pregnancy, she showed worsening weight loss, fever, night sweats, hoarseness, and coughs. At 31 weeks of pregnancy, a scatter shadow and cavitary lesions were detected on the chest radiograph. Acid- fast bacilli smear test and tuberculosis (TB) polymerase chain reaction tests yielded positive results (G-8), and she was diagnosed with TB. Contact tracing and screening indicated 3 patients with TB onset and 18 patients with latent TB infec- tion attributed to the initial patient, who infected a total of 36 people. In the present case, physicians were reluctant to order a chest radiograph for fear of harming the fetus and did not order sputum or interferon gamma release (IGRA) assay tests either. The diagnosis was delayed by 152 days, which was considered as a factor that caused the outbreak. The diag- nosis of TB in a pregnant patient may be very challenging because symptoms may initially be ascribed to the pregnan- cy, and delayed diagnosis and treatment of military TB can lead to the death of the mother and fetus. Consequently, to ensure early diagnosis and treatment, chest radiography and sputum and IGRA tests are recommended for pregnant women who have TB symptoms or are at high risk for TB.

ABSTRACT

Pneumonia is associated with an extremely high mortality rate in patients of late elderly age. Piperacillin/tazobactam and carbapenems are drugs of first choice for hospitalized patients with potentially resistant bacteria. We compared the efficacy and safety of piperacillin/tazobactam and biapenem. Among elderly patients with nursing- and healthcare-associated pneumonia, we extracted 53 patients treated with piperacillin/tazobactam and 53 patients treated with biapenem who were matched for sex, age, and severity of pneumonia. The average age was more than 80 years; most of the patients were middle- to oldest old in age. Although clinical efficacy was equally good, patients in the piperacillin/tazobactam group achieved significantly faster improvements on chest X-ray and body temperature on day 7. However, in the piperacillin/tazobactam group, nephrotoxicity frequently led to a need for a reduction in the dose or complete discontinuation of treatment. The average age of patients who developed significant nephrotoxicity was high, at 83.2 years. The biapenem group exhibited significantly better continuation of treatment than the piperacillin/tazobactam group. Toxicity profiles were different between the two groups. Hepatic toxicity was significantly higher in the biapenem group, whereas nephrotoxicity was significantly more common in the piperacillin/tazobactam group. Rate of decrease in bacteria was equally good between the two groups. Providing careful follow-up and conducting more detailed examinations, including studies to determine optimal dose and timing of administration, are necessary for the treatment of late elderly patients with numerous underlying diseases and potential organ dysfunctions.

ABSTRACT

A 44-year-old woman was admitted to our hospital because of a 15-month history of exertional dyspnea, nonproductive cough and fever. Thoracic high-resolution computed tomography (HRCT) showed centrilobular ground-glass opacities distributed in bilateral lung fields. She had worked at a down quilt factory and had been exposed to a large amount of feathers for 5 years. A peripheral lymphocyte proliferation test by positive was positive for pigeon serum. We diagnosed bird-related hypersensitivity pneumonia. After quitting her job, improvement of her clinical symptoms and chest imaging findings were observed and she has been free of relapse.
