Objective:
This study aimed to clarify differences in the positions of cone-beam computed tomography (CBCT) landmarks according to different midsagittal planes (MSPs) in patients with skeletal Class III facial asymmetry.
Methods:
Pre-treatment CBCT data from 60 patients with skeletal Class III were used.The patients were classified into symmetric (menton deviations of < 2 mm) or asymmetric (menton deviations of > 4 mm) groups. Six MSPs were established based on previous studies, and three-dimensional analyses were performed for the planes in both the groups. The measurement outcomes were compared statistically.
Results:
A statistically significant interaction (p < 0.01) was observed between MSPs and facial asymmetry. No significant differences were observed among MSPs in the symmetric group. However, significant differences in linear measurements were identified among MSPs in the asymmetric group. Specifically, the upper facial MSP revealed both maxillary and mandibular transverse asymmetries. On the other hand, anterior nasal spine (ANS)-associated MSP could not identify maxillary asymmetry. Furthermore, the menton deviation was approximately 3 mm lower when estimated using the ANS-associated MSP than that using upper facial MSP.
Conclusions
The choice of MSP can significantly affect treatment outcomes while diagnosing patients with asymmetry. Therefore, care should be taken when selecting MSP in clinical practice.

The Korean Journal of Orthodontics 2023;53(6):402-419
Objective:
This study assessed the differences in soft tissue deviations of the nose, lips, and chin between different mandibular asymmetry types in Class III patients.
Methods:
Cone-beam computed tomography data from 90 Class III patients with moderate-to-severe facial asymmetry were investigated. The sample was divided into three groups based on the extent of mandibular rolling, yawing, and translation. Soft tissue landmarks on the nose, lips, and chin were investigated vertically, transversely, and anteroposteriorly. A paired t test was performed to compare variables between the deviated (Dv) and nondeviated (NDv) sides, and one-way analysis of variance with Tukey’s post-hoc test was performed for intergroup comparisons. Pearson’s correlation coefficient was calculated to assess the relationship between the soft and hard tissue deviations.
Results:
The roll-dominant group showed significantly greater differences in the vertical positions of the soft tissue landmarks between the Dv and NDv than other groups (P < 0.05), whereas the yaw-dominant group exhibited larger differences in the transverse and anteroposterior directions (P < 0.05). Moreover, transverse lip cant was correlated with the menton (Me) deviation and mandibular rolling in the roll-dominant group (P < 0.001); the angulation of the nasal bridge or philtrum was correlated with the Me deviation and mandibular yawing in the yaw-dominant group (P < 0.01).
Conclusions
The threedimensional deviations of facial soft tissue differed based on the mandibular asymmetry types in Class III patients with similar amounts of Me deviation. A precise understanding of soft tissue deviation in each asymmetry type would help achieve satisfactory facial esthetics.

The incidence of ectopic pregnancy has been increasing for many years and ectopic pregnancy is still a leading cause of maternal death although its mortality is reduced significantly with improved early diagnosis and treatment. Intraligamentous pregnancy, a subset of ectopic pregnancy, is one of the most unusual accident so that the diagnosis of intraligamentous pregnancy is hardly ever made prior to laparotomy. We experienced intraligamentous pregnancy with hemoperitoneum. So we presented a case with brief review of literature.

Artificial intelligence (AI) has rapidly transformed various aspects of life, and the launch of the chatbot “ChatGPT” by OpenAI in November 2022 has garnered significant attention and user appreciation. ChatGPT utilizes natural language processing based on a ”generative pre-trained transfer” (GPT) model, specifically the transformer architecture, to generate human-like responses to a wide range of questions and topics. Equipped with approximately 57 billion words and 175 billion parameters from online data, ChatGPT has potential applications in medicine and orthopedics. One of its key strengths is its personalized, easy-to-understand, and adaptive response, which allows it to learn continuously through user interaction. This article discusses how AI, especially ChatGPT, presents numerous opportunities in orthopedics, ranging from preoperative planning and surgical techniques to patient education and medical support. Although ChatGPT’s user-friendly responses and adaptive capabilities are laudable, its limitations, including biased responses and ethical concerns, necessitate its cautious and responsible use. Surgeons and healthcare providers should leverage the strengths of the ChatGPT while recognizing its current limitations and verifying critical information through independent research and expert opinions. As AI technology continues to evolve, ChatGPT may become a valuable tool in orthopedic education and patient care, leading to improved outcomes and efficiency in healthcare delivery. The integration of AI into orthopedics offers substantial benefits but requires careful consideration and continuous improvement.

To determine the optimal administration route of calcitriol in CAPD patients with secondary hyperparathyroidism, we conducted a prospective study on 33 patients who performed CAPD for more than 6 months an d whose intact parathyroid hormone(iPTH) level was higher than 250pg/mL. The patients were randomized into 3 groups:IP(n=11); 1.0 microgram of calcitriol once daily via intraperitoneal route by overnight retention with dialysate, SC(n=11); 1.0 microgram of calcitriol three times a week via subcutaneous route, and PO (n=11); 1.0 microgram of calcitriol three times a week by ingestion. 11 out of 33 patients(6 in IP, 4 in SC, and 1 in PO) dropped out during the 6-months study period, and 5 among the 6 patients in IP were due to recurrent peritonitis. Biochemical data including calcium, phosphorus, iPTH, alkaline phosphatase, bone-specific alkaline phosphatase, osteocalcin and 1,25(OH)2D3 were measured regularly, and the data of 22 patients who had completed the 6-months study were analyzed. There was a statistically significant decrease in iPTH level(pg/mL) in the three groups after 6-months calcitriol therapy(IP; 812.0+/-276.7 vs. 354.7+/-129.4, PO; 571.8+/-330.7 vs. 159.6+/-192.3, SC; 786.1+/-535.0 vs. 551.8+/-729.9, respectively, P<0.05), but there were no differences in the percentage of decrease in iPTH from baseline values among the three groups. Alkaline phosphatase, bone- specific alkaline phosphatase and osteocalcin also decreased significantly in all three groups(IP; 50.1+/-14.6, 33.5+/-11.6, 52.3+/-10.9% of baseline value; SC; 80.9+/-14.8, 67.4+/-20.80, 54.4+/-11.1% of baseline value; PO; 48.8+/-24.4, 36.6+/-23.5, 54.2+/-11.6% of baseline value, respectively, P<0.05), but they were not different with each other. Among 22 patients who completed the 6-months study, hypercalcemia(Ca>=10.5 mg/dL) occurred in 7 patients(31.8%). IP(2/5, 40%) and SC groups(5/7, 71.4%) had significantly higher incidence of hypercalcemia than PO group(0/10, 0%) (P<0.05). IP group(2/5, 40%) also experienced significantly higher incidence of hyperphosphatemia than SC(1/7, 14.3%) and PO groups(1/10, 10%). Peritonitis occurred significantly more in IP than in SC and PO groups(P<0.05). In conclusion, calcitriol treatment resulted in a significant decrement in iPTH levels in CAPD patients and no significant differences were noted in the iPTH-suppressive effect of calcitriol according to the administration route. Because of higher incidence of peritonitis and hypercalcemia in IP and SQ groups, oral ingestion may be the most optimal route for calcitriol treatment in CAPD patients with secondary hyperparathyroidism.

PURPOSE: The purpose of this study was to compare the findings on high-resolution CT (HRCT) of the chest with those on video-assisted thoracoscopy for the detection of bullae in patients who had undergone an operation for spontaneous pneumothorax, and we also wished to evaluate the relationship between the characteristics of bullae on HRCT and development of spontaneous pneumothorax. MATERIALS AND METHODS: Fifty patients with spontaneous pneumothorax who had undergone both HRCT of the chest and video-assisted thoracoscopic surgery were included in the study. Spontaneous pneumothoraces were classified as either primary or secondary pneumothorax, and as initial or recurrent pneumothorax. The HRCT scans were obtained with 1 mm slice thickness and a 5 mm scan interval. Two radiologists retrospectively compared the HRCT findings of the chest with those findings on video-assisted thoracoscopy for the detection of bullae, and they evaluated the value of HRCT for diagnosing bullae. In addition, we assessed the size and number of bullae in these patients, and we also evaluated the relationship between those findings of bullae and the development of spontaneous pneumothorax. RESULTS: Bullae were detected in 40 patients by using video-assisted thoracoscopy, and HRCT showed bullae in 38 of these patients. Bullae were not identified with video-assisted thoracoscopy in the remaining ten patients, and among these ten patients, bullae were not demonstrated by HRCT in eight of them. Therefore, the sensitivity and specificity of HRCT for the detection of bullae were 95% (38/40) and 80% (8/10), respectively. The average size of the bullae of the affected hemithorax and the contralateral un-affected hemithorax was 1.97 cm+/-2.30 and 1.24 cm+/-1.46, respectively. Pneumothorax was more frequently observed in the hemithorax with larger bullae (p<0.05). The average numerical grade of the bullae (3.38+/-1.60) was higher in the affected hemithorax than in the contralateral un-affected hemithorax (2.96+/-1.86), but there was no statistically significant difference between both groups of hemithoraces (p>0.05). The average size of bullae in patients with secondary pneumothorax and those bullae of patients with primary pneumothorax was 4.44 cm+/-4.06 and 1.42 cm+/-1.26, respectively. The bullae were significantly larger in the patients with secondary pneumothorax than in those patients with primary pneumothorax (p<0.05). Although the average numerical grade of bullae was higher in the patients with secondary pneumothorax (4.00+/-1.58) than in those patients with primary pneumothorax (3.24+/-1.61), the difference between two groups was not statistically significant (p>0.05). CONCLUSION:HRCT of the chest would be a useful modality for detecting the bullae of those patients with spontaneous pneumothorax. The development of spontaneous pneumothorax is associated with the size of bullae rather than the number of bullae.
