[Two Cases of Lung Stage â ¢Squamous Cell Carcinoma Treated with Carboplatin (CBDCA)plus Nab-Paclitaxel(Nab-PTX)].

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.

[Comparison of pneumonia severity indices between modified A-DROP system and current A-DROP system predicting outcomes for patients hospitalized with community-acquired pneumonia].

BACKGROUND: The A-DROP is a predicting pneumonia severity index which is adopted in the Japanese Respiratory Society (JRS) guidelines. For community-acquired pneumonia, we made a modified A-DROP, adding two new index items to the current A-DROP. Then, we retrospectively compared the modified A-DROP with the current A-DROP regarding 30-day mortality. METHODS AND RESULTS: We analyzed consecutive 227 patients hospitalized with community-acquired pneumonia (mean age 79.0 years). The added index items were respiratory rate > or = 30/min and the presence or absence of underlying diseases. There were 16 fatalities (7.0%). In the extremely severe group, the sensitivities of the 30-day death and odds ratios were 19.9% and 9.5 in the current A-DROP, but 75.0% and 14.1 for the modified A-DROP, respectively. In addition, regarding the receiver-operating characteristic (ROC) area under the curve for the 30-day death ratio, the current A-DROP and modified A-DROP were 0.807 and 0.840, respectively. CONCLUSIONS: The modified A-DROP improved the ability to predict outcomes compared with the current A-DROP.

[A-DROP system might result in underestimation of severity of cases with Legionnaires' disease].

Fifteen cases of legionella pneumonia experienced in our department or associated hospital were included in this study. Each case was classified with the A-DROP system of the Japanese Respiratory Society Guidelines, and guidelines from the Infectious Diseases Society of America (IDSA) (1998) and then we compared the severity of the cases of pneumonia. Although 10 cases were classified as intermediate, 3 as severe, and 2 as extremely severe with the A-DROP system, most cases were classified as severe according to the IDSA guidelines. Among 5 fatal cases, three were ranked as intermediate with the A-DROP system. However all the fatal cases were ranked as severe in the IDSA guidelines. This study suggested that the A-DROP system might underestimate the severity of pneumonia in cases with legionella pneumonia.

Legionella pneumonia caused by Legionella pneumophila serogroup 2: second case report in Japan.

A 56-year-old man with a 3-day history of a chilly sensation and general fatigue presented to a hospital in his neighborhood. He was diagnosed as having pneumonia and immediately treated with intravenous ceftriaxone sodium, but his respiratory condition deteriorated and he developed symptoms of restlessness. Although Legionella urinary antigen detection tests were negative, his clinical course suggested Legionella pneumonia. After his treatment was changed to intravenous ciprofloxacin and oral clarithromycin, his general condition gradually improved. Later, Legionella pneumophila serogroup 2 was isolated from a bronchoalveolar lavage specimen. This was considered to be the causative organism. In our literature search, this was only the second case of Legionella pneumonia caused by Legionella pneumophila serogroup 2 in Japan.

Elsberg syndrome with eosinophilic meningoencephalitis caused by Angiostrongylus cantonensis.

A 42-year-old man was admitted to our hospital with a history of fever, headache and disorientation. His cerebrospinal fluid revealed eosinophilia and his serum had an antibody against Angiostrongylus cantonensis (A. cantonensis). Then, he was diagnosed as eosinophilic meningoencephalitis caused by A. cantonensis. He was treated with repeated lumbar punctures and oral prednisolone. Although a symptom he had been suffering from at the time of his admission was urinary retention, this symptom disappeared as his general condition improved. Therefore his case was considered to be Elsberg syndrome with eosinophilic meningoencephalitis caused by A. cantonensis.
