The structures forming the shoulder joint are very complex and the biomechanical effects of them on the joint are not clearly lunderstood. Frequently the long head of the biceps brachii muscle is dislocated naturally and it has been said that the supratubercular ridge, the depth, and angle of medial wall of the intertubercular groove are important. And the angles between the long axis of the humerus and the axis of head and neck are important clinically. So the authors studied them in the 105 specimens of the Korean adults humerus. The results are as follows: 1. The complete type of the supratubercular ridge was present in 22.9% and the partial type was in 53.3% 2. If the ridge was present, the spur of the lesser tubercle was present in 67.5% and if not present, the spur was in 8%. 3. The angle of medial wall of the intertubercular groove was variable, and the angle less than 45 was 13.41°. 4. The angles between the long axis of the humerus and the axis of head and neck were much greater in male than female (P<0.05). 5. The average diameter of the head of the humerus was 4.42±0.4cm in male and 4.4±0.4cm in female (P < 0.05).

3.The Role of Thermography in the Diagnosis of Breast Cancer.
Journal of the Korean Surgical Society 1998;54(5):631-639
Breast thermography produces a picture of the heat emitted from the surface of the breast. And abnormal temperature over the breast has been suggested as an indicator of malignancy. The mechanisms for the heat production at the area of the skin over the breast are suggested hypermetabolism, hypervascularization, and hyperfusion of the affected regions of the breast. The purpose of this study was to evaluate the diagnostic accuracy of breast thermography in breast cancer. One hundred thirty breast cancers and one hundred ten benign breast masses were examined by a digital infrared thermographic system (NEC San-ei, Therm Tracer 6T67) between January 1991 and December 1995. In this study, thermograms were classified as normal (Th-1), equivocal (Th-2), or abnormal (Th-3). Normal thermograms were those with normal symmetric vascularity, equivocal thermograms were those with only heat in the area of mass, and abnormal thermograms were those with heat and increased vascularity in the area of mass. Among the 110 benign breast masses, there were 98 Th-1 cases (89.1%), 2 Th-2 cases (1.8%) and 10 Th-3 cases (9.1%). Among the 130 breast cancers, there were 98 Th-3 cases (75.4%), 20 Th-2 cases (16.2%), and 12 Th-1 cases (9.2%). The sensitivity of the breast thermograms was 90%, the specificity 89.1%, and the diagnostic accuracy 89.6%. A thermal difference(deltaT) of less than 1oC was seen in 10 cases (7.7%) of breast cancer, and a deltaT of more than 1oC was seen in 120 cases (92.3%). Among the latter of a deltaT of more than 3oC was seen in 67 cases(51.4%). The correlation of the breast-cancer tumor size with deltaT was highly significant(p<0.0001). The classification of the thermographic diagnosis was found to be statistically correlated with tumor size (p<0.0001), axillary node status (p<0.001) and nuclear grade (p<0.05), but not with the presence or abscence of estrogen receptor. These results suggest that thermography is useful as a diagnostic tool for breast cancer. And that a deltaT of more than 2oC of on a breast thermogram strongly suqqests a malignancy.

4.The incidence of postoperative hemorrhage after tooth extraction in patients with thrombocytopenia
Journal of the Korean Association of Oral and Maxillofacial Surgeons 2021;47(3):190-196
Objectives:
The risk of bleeding after tooth extraction in thrombocytopenia patients remains unclear. Therefore, the present study aimed to assess the risk of bleeding after tooth extraction in patients with thrombocytopenia.
Materials and Methods:
The study included 220 patients who had a medical history of thrombocytopenia and underwent tooth extraction (330 teeth). The patients were divided into those who had thrombocytopenia (platelet count <150k) immediately before the tooth extraction, and those who had platelet counts that were between 150k and 250k before the extraction. Bleeding complications were recorded and compared between the patient groups.
Results:
Of the 220 patients, 130 underwent tooth extractions while having thrombocytopenia (platelet count <150k), and 90 had platelet counts that were between 150k and 250k before tooth extractions. Bleeding complications occurred in 11 patients (5.0%) of the 220 patients. Among those 11 patients with bleeding complications, 10 patients (7.7%) had thrombocytopenia (platelet count <150k) of the 130 patients, and 1 patient (1.1%) had a normal platelet count of the 90 patients. There was a significant difference between the patient groups regarding bleeding after extractions (P<0.001). No significant difference in the incidence of post-extraction bleeding was found between the subgroups by platelet count within the thrombocytopenia group.
Conclusion
Thrombocytopenia (platelet count <150k) increases the risk of post-tooth extraction bleeding. Therefore, bleeding control under the proper evaluation of hemostasis and performing delicate tooth extraction procedures using hemostatic plugs is necessary during the tooth extraction of patients with thrombocytopenia.

6.Congenital epulis in a newborn
Journal of the Korean Association of Oral and Maxillofacial Surgeons 2022;48(6):382-385
Congenital epulis (CE) is an extremely rare benign tumor of the gingiva that is found on the alveolar ridge of newborns, and the main treatment option is simple excision. Postoperative prognosis is very good, and spontaneous regression may occur despite incomplete excision. This report presented a rare case of CE and its healing process after surgery under local anesthesia. The treatment plan was decided upon through consultation between a medical team and the patient’s family, with surgical excision for the main lesion, which benefitted from surgery, and follow-up for a very small-sized lesion, which was thought to be appropriate for a newborn. No recurrence was found after its removal, and favorable healing was observed.

Torsion of a mucocele of the vermiform appendix is an extremely rare condition and also a rare cause of an acute abdomen with a clinical presentation that is indistinguishable from acute appendicitis, and thus, the condition is diagnosed during operation. Here, the authors describe the case of a 78-year-old female, who presented with intermittent abdominal pain. The appendix had a pelvic position and the torsion was counterclockwise. In addition, the torsion was associated with mucocele of the appendix, which was considered a secondary factor of torsion. Appendectomy and drainage were performed.

OBJECTIVE: To determine if birth weight greater than 4000gm can be predicted by ultrasound measurement of abdominal circumference(AC) and if shoulder dystocia in macrosomic infants can be predicted by ultrasound measurement of the difference between the abdominal diameter(AD) and biparietal diameter(BPD). METHODS: A Retrospective study was performed of births occuring from March, 1998 to August, 1999 at department of Obstetrics and Gynecology, College of Medicine, Chung-Ang University. Among neonates of birth weight greater than 4000 gm, 50 cases in that ultrasound examination was done within 2 weeks before delivery were selected for macrosomic group and 50 cases were selected for control group during the same period, among neonate of birth weight from 3100gm to 3900gm. RESULTS: 1) Normal spontaneous vaginal delivery(NSVD) was 41 cases in control group and 30 cases in macrosomic group. Among NSVD, shoulder dystocia was 1 case in 41 cases of control group and was 7 cases in 30 cases of macrosomic group. 2) On ultrasound measurement, 6 cases had AC greater than 35 cm in control group and 45 cases in macrosomic group. Among 30 cases in NSVD was done in macrosomic group, difference between AD and BPD was 2.9 0.271 cm when shoulder dystocia was existed and was 2.1 0.409 cm when shoulder dystocia was not existed. Between the two groups, statistically significant difference was detected. 3) When AC(cutoff value of 35cm) was used for screening of macrosomia, sensitivity for macrosomia was 88.2% and specificity was 89.8% and when AD-BPD difference(cutoff value of 2.6cm) was used for prediction of shoulder dystocia, sensitivity for shoulder dystocia was 66.6% and specificity was 95.2%. CONCLUSIONS: In prenatal ultrasound measurement, AC measurement at third trimester of pregnancy will be a valuable indicator for macrosomia screening. The AD-BPD difference of shoulder dystocia group was greater than uncomplicated group in macrosomia and the AD-BPD difference cutoff value of 2.6cm was significant value statistically.
