Objective: Worldwide, community-acquired pneumonia (CAP) is a common infection that occurs in older adults, who may have pulmonary comorbidities, including chronic obstructive pulmonary disease (COPD). Although there have been clinical studies on the coexistence of CAP with COPD, there remain some controversial findings. This review presents the current status of COPD in CAP patients, including the disease burden, clinical characteristics, risk factors, microbial etiology, and antibiotic treatment., Data Sources: A literature review included full peer-reviewed publications up to January 2018 derived from the PubMed database, using the keywords "community-acquired pneumonia" and "chronic obstructive pulmonary disease"., Study Selection: Papers in English were reviewed, with no restriction on study design., Results: COPD patients who are treated with inhaled corticosteroids are at an increased risk of CAP and have a worse prognosis, but data regarding the increased mortality remains unclear. Although Streptococcus pneumoniae is still regarded as the most common bacteria isolated from patients with CAP and COPD, Pseudomonas aeruginosa is also important, and physicians should pay close attention to the occurrence of antimicrobial resistance, particularly in these two organisms., Conclusions: COPD is a common and important predisposing comorbidity in patients who develop CAP. COPD often aggravates the clinical symptoms of patients with CAP, complicating treatment, but generally does not appear to affect prognosis., Competing Interests: There are no conflicts of interest

Background: Minimally invasive video-assisted thyroidectomy (MIVAT) has received increasing attention for malignant thyroid diseases. The aim of this study was to compare the outcomes of MIVAT with conventional open thyroidectomy (CT) for papillary thyroid microcarcinoma (PTMC)., Methods: Thirty-one patients were treated with MIVAT and 37 with CT. Their pathological characteristics, surgical complications, 5-year postoperative thyroglobulin (TG) and ultrasonic results were followed up., Results: All the patients took levothyroxine for suppressing thyroid stimulating hormone (TSH) after surgery, and were followed up with measurement of serum TG and neck ultrasonography at intervals of 6 or 12 months. There was no statistically significant difference between the CT and MIVAT groups for sex ratio, operation time, positive lymph nodes, complications and prognosis, but the MIVAT group had better cosmetic results., Conclusions: MIVAT did not differ significantly from CT for PTMC after 5 years follow-up, but it did have better cosmetic results. MIVAT is a safe and valid surgical technique for selected cases.

Background: Keyhole surgery has developed since the 1990s as a less invasive therapeutic strategy for intracranial lesions, initially for the treatment of intracranial aneurysms. The purpose of this study was to describe and evaluate the results of surgical treatment of lesions in the anterior fossa and sellar region via a supraorbital keyhole approach using eyebrow incisions., Methods: Between April 1994 and July 2003, 54 patients with lesions in the anterior fossa and sellar region were operated on via the supraorbital keyhole approach. The surgical results were studied retrospectively and compared with that of patients with lesions at the same locations but treated via a conventional subfrontal approach., Results: No significant difference in curative effect was found between the conventional subfrontal approach and the supraorbital keyhole approach. However, the supraorbital approach required a much smaller skin incision, causing less surgical trauma, while achieving excellent surgical exposure and good recovery., Conclusion: The supraorbital keyhole approach using an eyebrow incision is safe, effective, and both suitable and convenient for treating lesions in the anterior fossa and sellar region, with almost no adverse consequences on the facial features of patients.
