Purpose: Although advancements in medical treatments have been made, approximately half of patients with intestinal Crohn’s disease (CD) require intestinal resections during their lifetime. It is well-known that the nutritional status of CD patients can impact postoperative morbidity. The objective of this study was to evaluate the clinical significance of prognostic nutritional index (PNI) in patients with intestinal CD who underwent primary bowel resection. Materials and Methods: We retrospectively investigated patients who were diagnosed with CD and underwent intestinal surgery at Severance Hospital between January 2005 and October 2018. The patients were divided into two groups: PNI ≤40 (n=150) and PNI >40 (n=77). We assessed the clinical significance of PNI in terms of the incidence of postoperative infectious complications (PICs) and the postoperative recurrence of CD. Results: The low PNI group had significantly higher rates of infectious complications (32.0% vs. 10.4%, p=0.001) compared to the high PNI group. Multivariable analysis identified low PNI (≤40) and longer operation time (>180 min) as independent risk factors associated with PICs [odds ratio (OR)=2.754, 95% confidence interval (CI)=1.140–6.649, p=0.024; OR=2.986, 95% CI=1.451–6.143, p=0.003]. PICs were significantly associated with surgical recurrence (hazard ratio=2.217, 95% CI=1.064–4.617, p=0.034). Conclusion Preoperative PNI could serve as a predictive factor for PICs in CD patients who undergo intestinal resection. Additionally, PICs are significantly associated with a higher risk of surgical recurrence in CD.

In the rapidly evolving healthcare environment, radiologists strive to establish their rightful place.Thus, there is a need for enhanced outpatient and clinical education within the Department of Radiology and exploration of its methodologies. Accordingly, the Korean Society of Radiology established a task force to investigate the clinical and outpatient practice status of radiologists overseas, current state of related education, involvement of other specialties in radiologic practices and education in Korea, and clinical and outpatient practice status among Korean radiologists. Furthermore, a survey on clinical competency enhancement was conducted among the members of the Korean Society of Radiology. These findings suggest the need for visibility and clinical competency enhancement in radiologists and methodologies for strengthening clinical competencies.

Multiple cerebral infarctions coexisting with peripheral artery occlusion have been rarely reported and occur only in specific conditions. Also, the characteristics of thrombosis related to the outbreak of the coronavirus disease 2019 (COVID-19) have been observed and studied recently. We report a case of concurrent multiple cerebral infarctions and peripheral embolism in a patient with a recent history of COVID-19 infection. A 62-year-old male patient who had recently been infected with COVID-19 presented to our emergency department with left hemiparesis. Supportive treatments were given post the diagnosis of multiple cerebral infarctions in the right cerebral hemisphere. During the supportive treatments, motor weakness was seen in the right upper extremity. Computed tomography revealed thrombi in the right axillary, brachiocephalic, and brachial arteries. The patient was already taking antiplatelet and anticoagulant agents and had no other underlying disease to develop such occlusions except his recent history of COVID-19 infection. We checked his laboratory tests for coagulation profiles throughout the hospitalization to verify a possible cause. We believe that large thrombi formation due to COVID-19 can simultaneously cause embolism in the cerebrum and peripheral regions. This pathology can result in symptoms that could make diagnosis difficult, delaying treatment decisions. This report, therefore, suggests that it is necessary to take into account a patient’s history of COVID-19 infection in such situations, especially when the patient presents with symptoms of a stroke.

The need for a comprehensive nursing care service ward (CNCW) is emerging, but few studies have investigated its medical validity. This study aimed to assess the effect of hospitalization on functional recovery and fall incidence in poststroke patients. This retrospective study enrolled 354 patients with subacute stroke between July 2017 and April 2020. CNCW provided full caregiving and nursing to the patient. Baseline demographic and hospital data, including fall occurrence, were collected. Functional outcomes, including the Medical Research Council (MRC), Korean version of the Modified Barthel Index (K-MBI), and Korean version of the Mini-Mental State Examination (K-MMSE), were evaluated upon admission and discharge. One hundred seventy-two patients were hospitalized in CNCW among the 354 stroke patients. Initial and final K-MMSE and K-MBI were significantly higher in the CNCW group. The K-MMSE score gain was significantly lower in the CNCW group (p < 0.05). The fall occurrence was significantly higher in the CNCW group (p < 0.01). Hospitalization in CNCW adversely affected cognitive function after stroke. Falls were detected more frequently and reported in CNCW.

Adventitial cystic disease (ACD) is a rare, non-atherosclerotic disease that mainly affects the popliteal artery. Treatment is primarily surgical as endovascular approaches are affected by high recurrence rates. However, some studies have reported successful endovascular treatments of popliteal ACD cases. A 55-year-old female presented with right calf claudication. Computed tomography angiography revealed segmental occlusion of the right distal superficial femoral artery. Subsequently, a drug-eluting stent was successfully deployed. However, an unusual adventitial cystic lesion occluding the lumen that was characteristic of ACD was detected during a postoperative imaging review. It was aspirated using an ultrasound-guided percutaneous needle and drained using a pigtail catheter for 24 hours. Follow-up images after 39 months showed a patent artery with no recurrence of any cystic lesions, highlighting successful ACD treatment via stenting, ultrasound-guided aspiration, and cyst drainage. Stenting and cyst aspiration can be an alternative option for selected patients with ACD.
