In patients with recurrent spontaneous bacterial peritonitis, repeated inflammation may occasionally lead to fibrosis and adhesions within the peritoneal cavity, resulting in fibrous septations that give ascites a spider web-like appearance. These septations can interfere with the diffusion of antibiotics and hinder effective drainage of ascitic fluid, rendering standard treatment with antibiotics and paracentesis less effective—particularly when accompanied by refractory ascites. In this case, intraperitoneal administration of tissue plasminogen activator (tPA) via an indwelling catheter helped dissolve the fibrous septa and led to noticeable clinical improvement in a patient unresponsive to the standard therapy. However, intraperitoneal tPA therapy carries potential risks, including bleeding and infection. Therefore, it should be considered only after a thorough evaluation of the patient’s overall condition and bleeding risk, weighing the potential benefits against the possible complications.

Various acupuncture clinical trials have been conducted on migraine; however, the conclusions remain controversial especially when acupuncture was compared with sham acupuncture. Sham acupuncture is sometimes performed at the same acupuncture points used for verum acupuncture despite the evidence on acupuncture point specificity. Four databases were searched for sham acupuncture or waiting list-controlled acupuncture trials for migraine on December 25, 2023. Sham acupuncture was classified according to the needling points: sham acupuncture therapy at verum points (SATV) or at sham points (SATS). Network meta-analysis was performed based on the frequentist framework for headache pain intensity and response rate. A total of 18 studies involving 1936 participants were analyzed. Headache pain intensity and response rate were significantly improved in verum acupuncture compared with SATS. However, there was no significant difference between SATV and verum acupuncture. When comparing SATS and SATV, there was no significant difference in headache pain intensity and response rate; however, the results were in favor of SATV. The effect of the risk of bias on the certainty of evidence between verum and sham acupunctures was judged to be generally low. SATV should not be misused as a placebo control to evaluate the efficacy of acupuncture.

4.Causes and Clinical Characteristics of Compressive Optic Neuropathy in South Korean Patients
Korean Journal of Ophthalmology 2025;39(2):95-102
Purpose:
We aimed to investigate the causes and clinical features of compressive optic neuropathy in Koreans.
Methods:
We analyzed the medical records of patients diagnosed with compressive optic neuropathy from March 2014 to December 2023 to determine the cause of optic nerve compression, symptoms and symptom patterns at first visit, accompanying symptoms, types of visual field defects, and visual prognosis after surgery. In addition, the results of visual field tests and optical coherence tomography were analyzed to determine the positivity rate of each test and factors affecting test results.
Results:
A total of 73 patients were diagnosed with compressive optic neuropathy, and the most common cause was pituitary tumor (37 patients, 50.7%) followed by meningioma (16 patients, 21.9%), hemangioma (4 patients, 5.5%), thyroid ophthalmopathy (4 patients, 5.5%), and paranal sinus tumor tumor (2 patients, 2.7%). In terms of symptom pattern, half of the patients had vision and visual field defects that appeared gradually (41 patients, 56.2%), but there were also quite a few patients whose symptoms appeared suddenly (17 patients, 23.3%). The positivity rate of the diagnostic test was highest for visual field testing (89.0%). In pituitary tumors, tumor size affected diagnostic test results (p = 0.01).
Conclusions
The most common cause of compressive optic neuropathy in South Koreans was a pituitary tumor. Deterioration of visual function can also occur acutely, and visual field testing was useful for diagnosis.
6.Ocular Injuries in Patients with Old Blowout Fractures Following Blunt Trauma
Korean Journal of Ophthalmology 2025;39(1):57-63
Purpose:
To analyze the frequency and clinical characteristics of ocular injuries in patients with prior blowout fractures who experience new blunt trauma, and to assess whether old orbital fractures provide a protective effect against subsequent ocular trauma.
Methods:
The medical records of 1,315 ocular trauma patients were reviewed. A total of 927 patients who had orbital or facial computed tomography scans and ophthalmologist evaluations were considered. After applying exclusion criteria, 568 patients with 581 affected eyes were included in the final analysis. The patients were divided into two groups based on the presence of old blowout fractures, identified on computed tomography scan. The clinical characteristics and the frequency of ocular injuries were compared between the two groups. The risk of ocular injury according to the presence of old blowout fracture ware studied using multiple logistic regression after controlling age and sex.
Results:
Among the 581 eyes examined, 140 (24.1%) had old blowout fractures. The incidence of intraocular complications was significantly higher in the no orbital fracture group compared to the old blowout fracture group (20.4% vs. 2.1%, p < 0.001). Specifically, the incidence of complications such as gross hyphema (p = 0.001), globe rupture (p = 0.006), and vitreous hemorrhage (p = 0.027) was significantly greater in the group without old blowout fractures than in those with them. Multiple logistic regression showed that the presence of old blowout fractures was significantly associated with reduced risk of ocular injury (p < 0.001).
Conclusions
The patients with old blowout fractures had a lower risk of ocular injuries following subsequent blunt trauma. The findings suggest that old fractures may provide protective effect. These results may have important implications for the clinical management of patients at risk of recurrent orbital trauma.

Objective:
This study evaluated the effect of an accelerated three-dimensional (3D) T1-weighted pediatric brain MRI protocol using a deep learning (DL)-based reconstruction algorithm on scan time and image quality.
Materials and Methods:
This retrospective study included 46 pediatric patients who underwent conventional and accelerated, pre- and post-contrast, 3D T1-weighted brain MRI using a 3T scanner (SIGNA Premier; GE HealthCare) at a single tertiary referral center between March 1, 2023, and April 30, 2023. Conventional scans were reconstructed using intensity Filter A (Conv), whereas accelerated scans were reconstructed using intensity Filter A (Fast_A) and a DL-based algorithm (Fast_DL).Image quality was assessed quantitatively based on the coefficient of variation, relative contrast, apparent signal-to-noise ratio (aSNR), and apparent contrast-to-noise ratio (aCNR) and qualitatively according to radiologists’ ratings of overall image quality, artifacts, noisiness, gray-white matter differentiation, and lesion conspicuity.
Results:
The acquisition times for the pre- and post-contrast scans were 191 and 135 seconds, respectively, for the conventional scan. With the accelerated protocol, these were reduced to 135 and 80 seconds, achieving time reductions of 29.3% and 40.7%, respectively. DL-based reconstruction significantly reduced the coefficient of variation, improved the aSNR, aCNR, and overall image quality, and reduced the number of artifacts compared with the conventional acquisition method (all P < 0.05). However, the lesion conspicuity remained similar between the two protocols.
Conclusion
Utilizing a DL-based reconstruction algorithm in accelerated 3D T1-weighted pediatric brain MRI can significantly shorten the acquisition time, enhance image quality, and reduce artifacts, making it a viable option for pediatric imaging.

Neonatal Medicine 2025;32(1):49-54
Hydrops fetalis is a condition characterized by excessive fluid accumulation in the fetus, and is classified into immune and non-immune types depending on the underlying disease. Among cases of non-immune hydrops fetalis (NIHF), 15% to 20% are of cardiac origin, and genetic factors such as titin (TTN) gene mutations can contribute to cardiac dysfunction. We report the case of a preterm infant (29+2 weeks, 1,430 g) with hydrops fetalis who developed cardiac tamponade due to major pericardial effusion. Seven hours after birth, the heart rate suddenly decreased, and blood pressure could not be measured. Transthoracic echocardiography revealed substantial pericardial effusion and severely impaired cardiac function, and the preterm infant was diagnosed with pericardial tamponade. Emergency pericardiocentesis was performed, which led to hemodynamic stabilization. Genetic testing identified two heterozygous TTN mutations (c.13898A>T and c.27856G>T), with the latter presumed responsible for the observed cardiac dysfunction. The mother was found to carry the c.13898A>T mutation, but was asymptomatic. This case report highlights the importance of genetic testing in neonates with unexplained NIHF and cardiac complications. Identifying TTN gene mutations provides valuable insights into the underlying pathophysiology and guides clinical management.

Purpose:
11C-Methionine PET/CT is a promising method for detecting parathyroid lesions in patients with primary hyperparathyroidism (PHPT). We aimed to determine the diagnostic ability and correlation of digital 11C-Methionine PET/CT for parathyroid lesions in patients with PHPT, particularly in cases where standard imaging methods yielded inconclusive results.
Methods:
This retrospective analysis was conducted on patients diagnosed with PHPT who underwent digital 11C-Methionine PET/CT imaging because of ambiguous results on standard imaging work-up ( 99m Tc-MIBI parathyroid scan and/or neck ultrasonography). Quantitative 11C-Methionine PET/CT parameters, including maximum standardized uptake value (SUVmax), mean SUV (SUVmean), peak SUV (SUVpeak), parathyroid methionine volume (PMV), and whole methionine uptake(WMU: PMV multiplied by SUVmean) were calculated with various thresholds, and their correlations with biochemical andpathologic parameters were investigated.
Results:
This study included 22 consecutive patients (10 men and 12 women) with a median age of 64.0 years. The lesion detection rate and sensitivity of digital 11C-Methionine PET/CT were 81.8% (18/22) and 100.0% (18/18), respectively.Quantitative analysis revealed that serum PTH (r = 0.490, P = 0.039) and serum calcium (r = 0.583, P = 0.011) were signifi-cantly correlated with PMV50%.
Conclusion
Digital 11C-Methionine PET/CT offers good performance in the detection of parathyroid lesions in PHPT patients with inconclusive standard imaging work-up. The volume parameter of PMV50% significantly correlated biochemi-cal parameters and can serve as a complementary diagnostic tool.
