Objective: The unilateral biportal endoscopic posterior cervical foraminotomy (UBE-PCF) has been recently adopted for unilateral radiating arm pain due to cervical herniated intervertebral disc or foraminal stenosis. We systematically meta-analyzed clinical outcomes and complications of the UBE-PCF and compared them with those of full-endoscopic PCF (FE-PCF). Methods: We systematically searched the PubMed, Embase, and Web of Science until February 29, 2024. Clinical outcomes and complications of the UBE-PCF and FE-PCF were collected and analyzed using the fixed-effect or random-effects model. Clinical outcomes of the UBE-PCF were compared with minimal clinically important difference (MCID) following PCF to evaluate the efficacy of UBE-PCF. Results: Ten studies were included in the meta-analysis. In the random-effects meta-analysis, the Neck Disability Index (NDI), visual analogue scale (VAS) neck, and VAS arm were significantly decreased after the UBE-PCF (p<0.001). The improvement of NDI, VAS neck, and VAS arm were significantly higher than MCID (p<0.05). The improvement of NDI, VAS neck, and VAS arm were not significantly different between the UBE-PCF and FE-PCF (p>0.05). Overall incidence of complications of the UBE-PCF was 6.2% (24 of 390). The most common complication was dura tear (2.1%, 8 of 390). The incidence in overall complications was not significantly different between the UBE-PCF and FE-PCF (p=0.813). Conclusion We found that the UBE-PCF significantly improved clinical outcomes. Regarding clinical outcomes and complications, the UBE-PCF and FE-PCF were not significantly different. Therefore, the UBE-PCF would be an advantageous surgical option comparable to FE-PCF for unilateral radiating arm pain.

Background: Reference intervals defined for adults or children of other ethnicities cannot be applied in the evaluation of Korean pediatric patients. Pediatric reference intervals are difficult to establish because children are in their growing stage and their physiology changes continuously. We aimed to establish reference intervals for routine laboratory tests for Korean pediatric patients through retrospective multicenter data analysis. Methods: Preoperative laboratory test results from 1,031 pediatric patients aged 0 month–18 years who underwent minor surgeries in four university hospitals were collected. Age- and sex-specific reference intervals for routine laboratory tests were defined based on the Clinical and Laboratory Standards Institute (CLSI) EP28-A3c guidelines. Results: The pediatric reference intervals determined in this study were different from existing adult reference intervals and pediatric reference intervals for other ethnicities. Most tests required age-specific partitioning, and some of those required sex-specific partitioning for at least one age-partitioned subgroup. Erythrocyte sedimentation rate, monocyte percentage, basophil percentage, activated partial thromboplastin time, glucose, cholesterol, albumin, bilirubin, chloride, and C-reactive protein did not show any difference between age- or sex-partitioned subgroups. Conclusions We determined Korean pediatric reference intervals for hematology, coagulation, and chemistry tests by indirect sampling based on medical record data from multiple institutions. These reference intervals would be valuable for clinical evaluations in the Korean pediatric population.

Fungi are a major cause of human infections with diverse clinical manifestations. The incidence of fungal infections has increased over time, particularly in patients who have risk factors such as neutropenia, immune suppression, an intravascular catheter, parenteral nutrition, a prosthetic device, and prior broad spectrum antibiotic therapy. Here, we present an unusual case of co-infection by 2 distinct fungi, Candida parapsilosis and Trichosporon asahii, isolated from a patient who did not have any known risk factors initially, except active pulmonary tuberculosis. Despite the negative conversion of sputum acid-fast bacilli (AFB) culture test after treatment, clinical symptoms were refractory to therapy. The patient developed symptoms suggesting septic shock, and 2 distinct colonies were isolated from a blood specimen, which were identified as C. parapsilosis and T. asahii by MALDI-TOF and rRNA sequencing. Fever and hypotension were relieved after anti-fungal agent injection, and pulmonary lesions identified by imaging also improved.

BACKGROUND: Newborn screening of tyrosinemia type 1 is important for identifying infants at risk for developing this disease before life-threatening symptoms occur. It is difficult to differentiate between tyrosinemia type 1 and transient neonatal tyrosinemia (TNT) by analyzing tyrosine alone. Thus, succinylacetone must be analyzed. In this study, we measured succinylacetone in dried blood spot (DBS) by HPLC-tandem mass spectrometry (HPLC-MS/MS) and established cut-off values. METHODS: We used the hydrazine derivatization method to measure succinylacetone in 127 DBSs showing normal results in the newborn screening test and 93 DBSs showing increased tyrosine levels. We established cut-off values using the 99.9th percentile value or median+5 standard deviation value. RESULTS: Succinylacetone levels determined by our method were well-correlated with the results recommended by the Centers for Disease Control and Prevention for proficiency testing (r=0.9968). The succinylacetone levels in normal newborn DBSs were significantly lower than those in DBSs with high tyrosine levels (P < 0.001). The cut-off values were calculated to be 1.3 µM from the results of 127 normal DBS samples and 2.2 µM from 220 DBSs, including in 93 newborns with TNT. CONCLUSIONS: Measurement of succinylacetone in DBSs by HPLC-MS/MS is useful in individuals with increased tyrosine concentrations and can be used for rapid differential diagnosis of tyrosinemia when an appropriate cut-off value is established.

BACKGROUND AND OBJECTIVES: This trial evaluated the safety and efficacy of the Genoss drug-eluting coronary stent. METHODS: This study was a prospective, multicenter, randomized trial with a 1:1 ratio of Genoss drug-eluting stent (DES)™ and Promus Element™. Inclusion criteria were the presence of stable angina, unstable angina, or silent ischemia. Angiographic inclusion criteria were de novo coronary stenotic lesion with diameter stenosis >50%, reference vessel diameter of 2.5–4.0 mm, and lesion length ≤40 mm. The primary endpoint was in-stent late lumen loss at 9-month quantitative coronary angiography follow-up. Secondary endpoints were in-segment late lumen loss, binary restenosis rate, death, myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), and stent thrombosis during 9 months of follow-up. RESULTS: We enrolled 38 patients for the Genoss DES™ group and 39 patients for the Promus Element™ group. In-stent late lumen loss at 9 months was not significantly different between the 2 groups (0.11±0.25 vs. 0.16±0.43 mm, p=0.567). There was no MI or stent thrombosis in either group. The rates of death (2.6% vs. 0%, p=0.494), TLR (2.6% vs. 2.6%, p=1.000), and TVR (7.9% vs. 2.6%, p=0.358) at 9 months were not significantly different. CONCLUSION: This first-in-patient study of the Genoss DES™ stent showed excellent angiographic outcomes for in-stent late lumen loss and major adverse cardiac events over a 9-month follow-up.

BACKGROUND: Blood loss due to laboratory phlebotomy among neonates is correlated with anemia as well as transfusion. In this study, microcolumn agglutination cards for performing ABO & RhD blood typing and direct antiglobulin tests in neonates were evaluated and compared with other established systems. Also, the blood group antibody production rates according to the age were calculated to determine the upper age limit for the new method. METHODS: Eighty subjects were tested by using the DianaGel Neonatal cards (Diagnostic Grifols, Barcelona, Spain), and the results were compared with those of the slide methods for ABO and RhD blood typing, and the DiaMed-ID DC-Screening I test (DiaMed, Morat, Switzerland) for direct antiglobulin tests. A total of 546 subjects who were under 12 months old were tested for the ABO back-typing, and 58 subjects with the AB blood type were excluded. RESULTS: The results of the DianaGel Neonatal card were in agreement with those of the conventional methods for all the subjects. Only one subject showed a discrepant result for the DAT between the DianaGel and DiaMed methods. Blood group antibodies were detected in 29 out of 169 (17.2%) one-day-old neonates, in eight out of 34 (23.5%) infants between one and three months of age and in 81 out of 96 (84.4%) infants between six and twelve months of age. CONCLUSION: The DianaGel Neonatal card showed at least equivalent performance as compared to that of the conventional methods, and it showed advantages for a low blood volume requirement and stronger agglutination grades. The DianaGel card is a suitable alternative for blood typing and DAT in infants under the age of 3 months and who do not necessarily need back-typing of the blood groups due to the low production rate of antibodies.
