Background:
Intraoperative hemoglobin (Hb) monitoring is critical for ensuring patient safety during bimaxillary orthognathic surgery. Intraoperative Hb monitoring performed using portable devices with arterial blood samples is invasive, is time-consuming, and lacks the ability to provide real-time information. This retrospective study investigated the correlation between continuous and real-time total Hb (SpHb) using a Masimo Radical 7 device and Hb levels derived by portable devices during bimaxillary orthognathic surgery.
Methods:
Patients who underwent elective bimaxillary orthognathic surgery were enrolled. The correlation between SpHb and laboratory Hb (Lab-Hb) was evaluated immediately after the induction of anesthesia (T1) and at surgical closure (T2) and compared with postoperative Hb.
Results:
Eighty-eight patients were included. The correlation coefficients between SpHb and Lab-Hb were 0.795 and 0.859 at T1 and T2, respectively. The correlation coefficient between Lab-Hb at T2 and postoperative Hb was 0.918. A Bland-Altman analysis of the Lab-Hb at T2 and postoperative Hb showed a mean bias of 0.49.
Conclusion
In conclusion, here we demonstrated acceptable accuracy of the SpHb measured by the Masimo Radical 7 device during bimaxillary orthognathic surgery. However, SpHb is valuable as an adjunct value to Lab-Hb and a substitute for Hb monitoring due to its wide limits of agreement. These findings suggest that SpHb can help guide the timing of invasive blood sampling for Hb measurements, which may facilitate earlier intervention and treatment.

Background:
Individuals with disabilities often face significant barriers to receiving appropriate dental care due to limited cooperation, communication difficulties, and underlying medical conditions. Dental treatment under general anesthesia (GA) is an effective alternative for patients who are unable to tolerate conventional outpatient procedures. This study aimed to analyze cases of dental treatment under GA performed at the Gyeongnam Dental Clinic Center for the Disabled and to compare them with findings from other regional centers in Korea.
Methods:
A retrospective review of 181 cases of dental treatment under GA performed at the Gyeongnam Center between November 8, 2022, and October 30, 2024, was conducted. Patient data, including demographic characteristics, disability type, American Society of Anesthesiologists (ASA) physical status classification, treatment type, number of GA sessions, procedure duration, and regional residence, were collected from anonymized electronic medical records. Statistical comparisons were made with findings from previous studies to assess trends and clinical implications.
Results:
Among the 181 patients treated under GA, 61.9% were male, with a mean age of 22.4 years. Intellectual disabilities (41.4%) and autism spectrum disorder (28.6%) were the most common indications. Most patients were classified as ASA class II (60.8%) and underwent an average of 14 procedures per session, with restorative treatment being the most frequent (43.5%). Single-session treatments were predominant (90.9%), with an average duration of 147.5 m. Most patients resided in Gyeongsangnam-do (62.4%), reflecting the center's geographic accessibility.
Conclusion
This study provides foundational data on dental treatment under GA for individuals with disabilities at a regional center. The findings emphasize the need for specialized facilities, efficient treatment planning, and structured follow-up systems. Improved accessibility and financial support are essential to enhancing oral health outcomes in this population. Future studies should include pediatric cases and account for overlapping disabilities to better reflect clinical complexity.

OBJECTIVE: Impairment of spermatogenesis has been identified as an inevitable side effect of cancer treatment. Although estrogen treatment stimulates spermatogenic recovery from the impaired spermatogenesis by suppressing the intra-testicular testosterone (ITT) level, side effects of estrogen are still major impediments to its clinical application in humans. Soybeans are rich in genistein, which is a phytoestrogen that binds to estrogen receptors and has an estrogenic effect. We investigated the effects of genistein administration on ITT levels, testis weight, and recovery of spermatogenesis in rats treated with a chemotherapeutic agent, busulfan. METHODS: Busulfan was administered intraperitoneally to rats, and then a GnRH agonist was injected subcutaneously into the back, or genistein was administered orally. RESULTS: The weight of the testes was significantly reduced by the treatment with busulfan. The testis weight was partially restored after busulfan treatment by additional treatment with either the GnRH agonist or genistein. Busulfan also induced atrophy of a high percentage of the seminiferous tubules, but this percentage was decreased by additional treatment with either the GnRH agonist or genistein. Treatment with genistein was effective at suppressing and maintaining ITT levels comparable to that in the GnRH agonist group. CONCLUSION: Genistein effectively suppressed ITT levels and stimulated the recovery of spermatogenesis in rats treated with a chemotherapeutic drug. This suggests that genistein may be a substitute for estrogens, for helping humans to recover fertility after cancer therapy without the risk of side effects.

Cystic nephroma (CN) is a benign cystic neoplasm composed of mixed epithelial and stromal elements. Less than 200 cases have been reported. We had a patient, a 41-year-old woman, who had a huge typical CN. The patient was admitted for a right renal mass that was found incidentally. On laparaoscopic right nephrectomy, there was an encapsulated 7 cm multilocular cystic mass at the upper pole. Microscopically, the cystic wall was lined by a single layer of low cuboidal or hobnail epithelium without a solid area. The thin septa were composed of bland, ovarian type spindle cells. The main differential diagnoses were mixed epithelial and stromal tumor (MEST), low grade multilocular renal cell carcinoma, and tubulocystic carcinoma. The results of immunohistochemical staining were cytokeratin 7/19(+/+) and CD10(-) in lining epithelium, estrogen receptor/progesterone receptor(+/+) in stromal cells. After surgery, she was free of recurrence for 10 months. We report this rare case and compare it with other cystic renal tumors, especially MEST.

Nephrotic syndrome has been considered a hypercoagulable state because thromboembolic events of the venous or the arterial circulations occur on occasion. There are various risk factors for thromboembolism in patients with nephrotic syndrome (membranous nephropathy, severe hypoalbuminemia, hemoconcentration and medications such as steroid and diuretics). As thromboembolism is often fatal, early detection and proper management are important. Although anticoagulation is the preferred therapy, thrombolysis may be considered for an extensive thrombosis, for inferior vena cava (IVC) thrombosis, for recurrent pulmonary thromboembolism and for bilateral renal vein thrombosis in conjunction with acute renal failure. We report here on a case of renal vein and IVC thrombosis in a 24-year-old male with nephrotic syndrome, and this patient was treated with intravenous thrombolytics rather than anticoagulation and local thrombolytic infusion. He complained of left flank pain and his CT scan revealed left renal vein thrombosis and IVC thrombosis. After urokinase infusion, his thrombi were resolved successfully without bleeding complications.
