Case Reports
Pyogenic knee arthritis caused by group A β-hemolytic Streptococcus: a toxic shock-prevented case.
Pyogenic knee arthritis caused by group A β-hemolytic Streptococcus (GAS) is rare. GAS sometimes causes group A β-hemolytic streptococcal toxic shock syndrome. We encountered a case of pyogenic knee arthritis caused by GAS that resolved after appropriate treatment (emergency arthroscopic synovectomy and medication) administered within 48 h of onset. In cases of a history of another infection with acute knee joint pain, the possibility of GAS-induced pyogenic knee arthritis should be considered, and proper treatment should be administered immediately.

Randomized Controlled Trial Comparative Study
A comparative study of treatments for chronic subdural hematoma: burr hole drainage versus burr hole drainage with irrigation.
Although chronic subdural hematoma (CSDH) is one of the most common entities encountered in neurosurgical practice, optimal surgical treatment for CSDH remains controversial. This study retrospectively compared results for CSDH between burr hole drainage alone and burr hole drainage with irrigation. Ninety-two patients with CSDH underwent surgery at our institution from January 1998 through December 2009. ⋯ The recurrence rate was higher in Group A compared to Group B (10.3% vs. 2.9%). The authors used logistic regression analysis to identify factors associated with the outcome of CSDH, and found that duration of hospital stay, anti-coagulant therapy, presence of dementia and burr hole drainage alone were significantly associated with poor outcome of CSDH. These results indicate that burr hole drainage with irrigation has a significantly stronger association with good outcomes compared to drainage alone, and could be a reliable and effective operative method for the treatment of CSDH with a lower recurrence rate.

Comparative Study
Comparison of leukotriene receptor antagonists and anti-histamines as an add-on therapy in patients with asthma complicated by allergic rhinitis.
Patients with asthma are often complicated by allergic rhinitis, and the intimate pathophysiological association between allergic rhinitis and asthma often imposes a significant morbidity on affected individuals. The present study was conducted to assess the clinical efficacies of leukotriene receptor antagonists (LTRAs) and anti-histamines on asthma as an add-on therapy in patients with asthma complicated by allergic rhinitis. Consecutive patients with asthma were recruited to fill in systematic self-administered questionnaires concerning symptoms and conditions related to asthma and allergic rhinitis. ⋯ The initial survey indicated that the patients who were treated with LTRAs had significantly more severe asthma-related symptoms (i.e. wheeze, cough and sleep disturbance) and experienced greater dissatisfaction with the treatment than did those who were treated with anti-histamines. The second survey disclosed significant reductions in sneezing (p=0.03), rhinorrhea (p=0.01), dyspnea (p=0.046), sleep disturbance (p=0.02), over-all asthma symptoms (p=0.013), and an improvement in satisfaction with treatment (p=0.019) in patients to whom LTRAs were added-on, whereas the patients receiving anti-histamines reported no significant changes in these symptoms. These results suggest that LTRAs are more effective than anti-histamines as an add-on therapy in symptomatic patients with asthma complicated by allergic rhinitis.

Although being a rapidly expanding socioeconomical burden worldwide, chronic obstructive pulmonary disease (COPD) is often overlooked because of its insidious progression. Since spirometry is the primary tool for the diagnosis of COPD, physicians should be aware of the disease in any situation where interpreting spirometry. This study was to estimate the prevalence of undiagnosed COPD among patients who underwent spirometry as a preoperative evaluation for elective surgeries. ⋯ The remaining 194 patients with AL (74%) were suspected to have undiagnosed COPD, 90% of which was mild in severity. Only 30 (15%) of these patients appeared to be diagnosed have received a diagnosed as COPD by physician on this occasion. This study testifies that COPD is often unnoticed, and demonstrates that every spirometry, such as in preoperative evaluation, gives a clue to identify affected individuals, for which awareness of the disease is essential.

The Streptococcus milleri group are becoming increasingly recognized as important pulmonary pathogens which may lead to the development of empyema or lung abscesses. Although several small series have been reported, the clinical and laboratory features of Streptococcus milleri infection have yet to be fully characterized in the elderly. We retrospectively examined the clinical features of 19 patients with Streptococcus milleri pulmonary disease who were admitted to our hospital between 2000 and 2002, based on their clinical records and laboratory data. ⋯ The most common symptoms at presentation were shortness of breath, coughing, sputum, and weight loss. An underlying disease existed in 14 of the 19 cases. We conclude that the Streptococcus milleri group is a more important cause of pulmonary infections than has been previously recognized.
