Antimicrobial Resistance and Clinical Outcomes in Nursing Home-Acquired Pneumonia, Compared to Community-Acquired Pneumonia

PURPOSE: Patients with nursing home-acquired pneumonia (NHAP) should be treated as hospital-acquired pneumonia (HAP) according to guidelines published in 2005. However, controversy still exists on whether the high mortality of NHAP results from multidrug resistant pathogens or underlying disease. We aimed to outline differences and factors contributing to mortality between NHAP and community-acquired pneumonia (CAP) patients. MATERIALS AND METHODS: We retrospectively evaluated patients aged 65 years or older with either CAP or NHAP from 2008 to 2014. Patients with healthcare-associated pneumonia other than NHAP or HAP were excluded. RESULTS: Among 317 patients, 212 patients had CAP and 105 had NHAP. Patients with NHAP had higher mortality, more frequently used a ventilator, and had disease of higher severity than CAP. The incidences of aspiration, tube feeding, and poor functional status were higher in NHAP. Twenty three out of 54 NHAP patients and three out of 62 CAP patients had multidrug resistant pathogens (p<0.001). Eleven patients with NHAP died at discharge, compared to 7 patients with CAP (p=0.009). However, there was no association between mortality rate and presence of multidrug-resistant pathogens. The number of involved lobes on chest X-ray [odds ratio (OR)=1.708; 95% confidence interval (CI), 1.120 to 2.605] and use of mechanical ventilation (OR=9.537; 95% CI, 1.635 to 55.632) were significantly associated with in-hospital mortality. CONCLUSION: Patients with NHAP had higher mortality than patients with CAP. The excess mortality among patients with NHAP and CAP was related to disease severity but not to the presence of multidrug resistant pathogens.

The Association between the Therapeutic Agent and the Compliance of the Patients with Inflammatory Bowel Diseases / 대한소화기학회지

BACKGROUND/AIMS: Adherence of the patients with inflammatory bowel diseases is important to maintain the remission. However, the patients do not always keep their appointments for treatment. The aim of this study was to investigate the clinical factors associated with adherence of patients in terms of appointment keeping. METHODS: A total of 73 subjects were retrospectively investigated from September 2005 to January 2012 at Dongguk University Ilsan Hospital (Goyang, Korea). We reviewed medical records including the age, sex, residence, medications, the disease activity, and the rate of keeping the date. A punctual visit was defined as outpatient visit on the scheduled date +/-7 days. Punctual patients for the visit were defined as their punctual visit rates exceed 90%. RESULTS: Male to female ratio was 2.4:1. Mean age was 41.5+/-15.4 years (range, 20 to 78 years). Ulcerative colitis was 53 cases (72.6%) and Crohn's disease was 20 cases (27.4%). Mean duration of disease was 42.0+/-41.6 months (range, 4 to 226 months). Mean puntual visit rate was 86.7+/-16.0% (range, 27 to 100). Thirty-eight patients (52.1%) were punctual patients for the visit. Azathioprine/6-mercaptopurine treatment was associated with punctual patients for the visit (odd ratio, 3.19; 95% confidence interval, 1.12 to 9.09; p=0.03). However, other clinical factors did not influence the punctual visit rates. CONCLUSIONS: Our study demonstrated that the use of azathioprine/6-mercaptopurine was associated with keeping the appointment for meeting the doctor. Further prospective study would be necessary.

A Case of Podostroma Cornu-Damae Intoxication Similar to Drug Hypersensitivity Syndrome / 대한내과학회지

The clinical aspects of intoxication can be similar to those of drug hypersensitivity syndrome, including desquamation, hematologic abnormalities, multiple organ failure, and even death. Many people consume mushrooms that they collect in the mountains, and consequently, the incidence of poisonous mushroom intoxication is increasing. Podostroma cornu-damae is a poisonous mushroom not well-known to the public that contains trichothecene, a deadly poison. It is difficult to differentiate P. cornu-damae from other edible mushrooms, especially young Ganoderma lucidum. Therefore, the general public should be aware of the dangers of indiscreet ingestion of mushrooms. When physicians treat patients presenting clinical symptoms similar to those of drug hypersensitivity reaction following the intake of mushrooms, poisonous mushroom intoxication must be taken into consideration. We report this case together with a literature review, as we experienced one P. cornu-damae intoxication case showing similar clinical aspects to drug hypersensitivity syndrome.
