Osteopathia striata with cranial sclerosis (OSCS) is a rare genetic disorder characterized by skeletal abnormalities, cranial sclerosis, and various associated features. In this case report, we present the case of a patient with OSCS who complained of unilateral facial palsy. We discuss the clinical presentation, radiological findings, and genetic analysis, highlighting the importance of early diagnosis and multidisciplinary management in these cases.

This study aimed to investigate differences in intrinsic prefrontal functional connectivity according to the presence of cognitive impairment in patients with end-stage renal disease (ESRD) using functional near-infrared spectroscopy (fNIRS). Methods: We prospectively enrolled 37 patients with ESRD who had been undergoing hemodialysis for more than 6 months and had no history of neurological or psychiatric disorders. All patients with ESRD underwent the Korean version of the Montreal Cognitive Assessment (MoCA-K) to assess cognitive function. The NIRSIT Lite device (OBELAB Inc.) was used to acquire fNIRS data, and the NIRSIT Lite Analysis Tool program was used to process the data and generate a functional connectivity matrix. We obtained functional connectivity measures by applying graph theory to the connectivity matrix using the BRAPH (brain analysis using graph theory) program. Results: Of the 37 patients with ESRD, 23 had cognitive impairment, whereas 14 patients showed no cognitive impairment. Intrinsic prefrontal functional connectivity was significantly different between groups. Network measures of strength, global efficiency, and mean clustering coefficient were lower in ESRD patients with cognitive impairment than in those without cognitive impairment (4.458 vs. 5.129, p = 0.02; 0.397 vs. 0.437, p = 0.03; and 0.316 vs. 0.421, p = 0.003; respectively). There were no significant correlations between MoCA-K scores and clinical characteristics. Conclusion: We demonstrated a significant association between cognitive function and intrinsic prefrontal functional connectivity in patients with ESRD. ESRD patients with cognitive impairment have reduced connectivity and segregation in the prefrontal brain network compared to those without cognitive impairment.

Emphysematous prostatitis with an abscess is an extremely rare but lethal infection, characterized by the accumulation of gas and purulent exudates. Due to its rarity, severity, and nonspecific presentation, prompt diagnosis and treatment are crucial to achieve favorable clinical outcomes. This report presents a 43-year-old male with hemodialysis-dependent end-stage kidney disease who reported a 3-day history of fever, urinary incontinence, dysuria, and dyspnea. His condition rapidly deteriorated due to septic shock caused by emphysematous prostatitis with an abscess. Following extensive treatment including long-term parenteral antibiotics, polymyxin B hemoperfusion filter treatment, abscess drainage via transurethral resection of the prostate, and suprapubic cystostomy, the patient successfully recovered.

This report presents a unique case of an endocervical polyp-mimicking malignancy on pelvic MRI in a 45-year-old female. The MRI depicted a multilocular cystic lesion with an enhancing solid component, raising suspicion for malignancy. However, histopathological examination definitively revealed a benign endocervical polyp. This case highlights the limitations of diagnosing cervical lesions solely on MRI features, emphasizing the potential for benign conditions to mimic malignancy.

Purpose: This study investigated whether the respiratory phase during pleural puncture in CT-guided percutaneous transthoracic needle biopsy (PTNB) affects complications. Materials and Methods: We conducted a retrospective review of 477 lung biopsy CT scans performed during free breathing. The respiratory phases during pleural puncture were determined based on the table position of the targeted nodule using CT scans obtained during free breathing. We compared the rates of complications among the inspiratory, mid-, and expiratory respiratory phases. Logistic regression analysis was performed to control confounding factors associated with pneumothorax. Results: Among the 477 procedures, pleural puncture was performed during the expiratory phase in 227 (47.6%), during the mid-phase in 108 (22.6%), and during the inspiratory phase in 142 (29.8%). The incidence of pneumothorax was significantly lower in the expiratory puncture group (40/227, 17.6%; p = 0.035) and significantly higher in the mid-phase puncture group (31/108, 28.7%; p = 0.048). After controlling for confounding factors, expiratory-phase puncture was found to be an independent protective factor against pneumothorax (odds ratio = 0.571; 95% confidence interval = 0.360–0.906; p = 0.017). Conclusion Our findings suggest that pleural puncture during the expiratory phase may reduce the risk of pneumothorax during image guided PTNB.
