Various strains can be found in emphysematous prostatic abscesses (EPAs), but the most frequent causative organism is Klebsiella pneumoniae . Hypervirulent K. pneumoniae can disseminate to distant sites by forming a muco-polysaccharide network outside the capsule. Here, we present the first case of K. pneumoniae in an EPA accompanied by a spinal cord infarction. A 65-year-old man was referred to our hospital due to sudden-onset paraplegia after a 5-day history of fever, myalgia, and voiding difficulty. Abdominal computed tomography revealed a collection of air pockets in the prostate, and diffusion-weighted magnetic resonance imaging showed high signal intensity in the thoracic spinal cord. The patient was initially treated with antibiotics and surgical drainage. On the third hospital day, therapeutic heparin was added after discussion with a neurologist. The patient had no inflammatory symptoms, experienced some improvement in paraplegia, and was discharged on the 14th hospital day. This study adhered to the case report guidelines.

Purpose: This study aimed to assess the clinical outcome and safety of holmium laser enucleation of the prostate (HoLEP) following transrectal ultrasound-guided prostate biopsy (TR biopsy) in the treatment of benign prostate hyperplasia. Materials and Methods: We retrospectively analyzed data from 556 patients who underwent HoLEP between 2014 and 2021. The patients were categorized into six groups: Group 1-A (n=45) underwent HoLEP within four months post TR biopsy. Group 1-B (n=94) underwent HoLEP more than four months post TR biopsy. Group 1-C (n=120) underwent HoLEP after a single TR biopsy. Group 1-D (n=19) underwent HoLEP after two or more TR biopsies. Group 1-total (n=139, group 1-A+group 1-B or group 1-C+group 1-D) underwent HoLEP post TR biopsy. Group 2 (control group, n=417) underwent HoLEP without prior TR biopsy. We examined perioperative parameters, safety, and functional outcomes. Results: The age, body mass index, International Prostate Symptom Score (IPSS), uroflowmetry, and comorbid diseases between group 1-total and group 2 were comparable. However, group 1-total exhibited significantly elevated prostate-specific antigen levels and larger prostate volumes (p<0.01). Perioperative factors like enucleation time, enucleation weight, and catheterization duration were notably higher in group 1-total (p<0.01). All groups showed significant improvements in IPSS, postvoid residual urine, and maximum flow rate during the 1-year postoperative period (p<0.05). The rates of postoperative complications were similar between group 1-total and group 2. Conclusions Enucleation time and catheterization duration were significantly longer in the TR biopsy group. However, postoperative complications were not significantly different between TR biopsy and non-TR biopsy groups.

Background/Aims: To investigate whether non-alcoholic fatty liver disease (NAFLD) in individuals without generalized obesity is associated with visceral fat obesity (VFO), sarcopenia, and/or myosteatosis. Methods: This cross-sectional analysis included 14,400 individuals (7,470 men) who underwent abdominal computed tomography scans during routine health examinations. The total abdominal muscle area (TAMA) and skeletal muscle area (SMA) at the 3rd lumbar vertebral level were measured. The SMA was divided into the normal attenuation muscle area (NAMA) and low attenuation muscle area, and the NAMA/TAMA index was calculated. VFO was defined by visceral to subcutaneous fat ratio, sarcopenia by body mass index-adjusted SMA, and myosteatosis by the NAMA/TAMA index. NAFLD was diagnosed with ultrasonography. Results: Of the 14,400 individuals, 4,748 (33.0%) had NAFLD, and the prevalence of NAFLD among non-obese individuals was 21.4%. In regression analysis, both sarcopenia (men: odds ratio [OR] 1.41, 95% confidence interval [CI] 1.19–1.67, P<0.001; women: OR=1.59, 95% CI 1.40–1.90, P<0.001) and myosteatosis (men: OR=1.24, 95% CI 1.02–1.50, P=0,028; women: OR=1.23, 95% CI 1.04–1.46, P=0.017) were significantly associated with non-obese NAFLD after considering for VFO and other various risk factors, whereas VFO (men: OR=3.97, 95% CI 3.43–4.59 [adjusted for sarcopenia], OR 3.98, 95% CI 3.44–4.60 [adjusted for myosteatosis]; women: OR=5.42, 95% CI 4.53–6.42 [adjusted for sarcopenia], OR=5.33, 95% CI 4.51–6.31 [adjusted for myosteatosis]; all P<0.001) was strongly associated with non-obese NAFLD after adjustment with various known risk factors. Conclusions In addition to VFO, sarcopenia and/or myosteatosis were significantly associated with non-obese NAFLD.

Background: The association of myosteatosis measured using visual muscular quality map in computed tomography (CT) with nonalcoholic fatty liver disease (NAFLD), its severity, and fibrosis was analyzed in a large population. Methods: Subjects (n=13,452) with abdominal CT between 2012 and 2013 were measured total abdominal muscle area (TAMA) at L3 level. TAMA was segmented into intramuscular adipose tissue and skeletal muscle area (SMA), which was further classified into normal attenuation muscle area (NAMA) and low attenuation muscle area (LAMA). The following variables were adopted as indicators of myosteatosis: SMA/body mass index (BMI), NAMA/BMI, NAMA/TAMA, and LAMA/BMI. NAFLD and its severity were assessed by ultrasonography, and liver fibrosis was measured by calculating the NAFLD fibrosis score (NFS) and fibrosis-4 index (FIB-4) scores. Results: According to multiple logistic regression analyses, as quartiles of SMA/BMI, NAMA/BMI, and NAMA/TAMA increased, the odds ratios (ORs) for NAFLD decreased in each sex (P for trend <0.001 for all). The ORs of moderate/severe NAFLD were significantly higher in the Q1 group than in the Q4 group for SMA/BMI, NAMA/BMI, and NAMA/TAMA in men. The ORs of intermediate/high liver fibrosis scores assessed by NFS and FIB-4 scores increased linearly with decreasing quartiles for SMA/BMI, NAMA/BMI, and NAMA/TAMA in each sex (P for trend <0.001 for all). Conversely, the risk for NAFLD and fibrosis were positively associated with LAMA/BMI quartiles in each sex (P for trend <0.001 for all). Conclusion A higher proportion of good quality muscle was associated with lower risks of NAFLD and fibrosis.

The hepatitis A virus (HAV) induces severe acute liver injury and is adapted to human and monkey cell lines but not other cells. In this study, the HAV was inoculated into porcine kidney (PK-15) cells to determine its infectivity in porcine cells. The growth pattern of the HAV in PK-15 cells was compared with its growth pattern in fetal rhesus kidney (FRhK-4) cells. The growth of HAV was less efficient in PK-15 cells. In conclusion, HAV replication was verified in PK-15 cells for the first time. Further investigations will be needed to identify the HAV-restrictive mechanisms in PK-15 cells.
