PURPOSE:Recent studies proposed that polyunsaturated fatty acids (PUFA) of the omega6 series (linoleic acid, LA) compared to the omega 3 series (linolenic acid, LNA) may be a potent promoters of adipogenesis during the gestation/lactation period. Increased ratio of LA/LNA may stimulate adipose tissue development during gestation/lactation period and may subsequently lead to chilhood obesity. The purpose of this study is to evaluate fatty acids composition of the breast milk in Korean lactating women and to analyze the relationship between LA/LNA and the body weight gain of the infants. METHODS:Fifty eight healthy postpartum lactating women and their healthy 58 breast feeding infants were studied. At 11.3+/-3.9 days of postpartum, breast milk were taken and analyzed by gas-liquid chromatography with one-step methylation method. RESULTS:The total fat contents in breast milk were 3.2+/-1.3%. The total fat contents in breast milk were not related to maternal BMI or Kaup index of infants. The percentage of PUFA was 24.9+/-6.0%. Among these PUFA, the percentage of LA and LNA was 20.3+/-5.8% and 2.2+/-0.8%, respectively. LA/ LNA ratio was 10.2+/-2.5. There were no significant correlations between LA/LNA ratio and infant weight gain during the first 2 months of life. CONCLUSION: Short term weight gain of infant was not related to the LA/LNA ratio in the breast milk. Further studies on the long term effects on fat percent and body weight of infants would be needed.

Purpose:
To evaluate the effects and limitations of lacrimal endoscopy without silicone tube intubation in patients with epiphora.
Methods:
We conducted a retrospective chart review of 64 eyes in 49 patients who underwent lacrimal endoscopy between May 2021 and May 2022. The clinical characteristics, irrigation test results, lacrimal endoscopic findings, and type of surgery were analyzed.
Results:
The mean duration of symptoms was 31.2 months, and was significantly longer in the failure group than in the success group (p = 0.043). Irrigation tests showed passage, partial obstruction, and complete obstruction in 20 (31.3%), 16 (25.0%), and 28 (43.7%) eyes, respectively. Lacrimal endoscopy showed narrowing, mucus, fibrosis, granulation, and stones in 41 (64.0%), 12 (18.8%), 6 (9.3%), 3 (4.7%), and 2 (3.1%) eyes, respectively. Following lacrimal endoscopy, 32 (50.0%) eyes each were included in the success and failure groups. Preoperative irrigation test results did not affect the success rate (p = 0.203). Silicone tube intubation and dacryocystorhinostomy were performed in 5 (7.8%) and 8 (12.5%) eyes, respectively, because the symptoms did not improve after lacrimal endoscopy.
Conclusions
Lacrimal endoscopy, performed without silicone tube intubation, was effective in improving symptoms and may guide the choice of surgical technique, if required.

The biocompatibility of the titanium has been estabilished through various experimental studies such as cell culture toxicity test, pyrogen test, mutagen test and others. In order to confirm biocompatibility after fabrication of titanium and to clarify the difference between the bone reaction after insertion of the lathed titanium rods and the bone reaction after insertion of the finished and polished rods, both rods were implanted into the proximal femur of a rabbit. Histologic reactions in the bone were observed according to the ASTM standards at the intervals of 6 weeks, 12 weeks and 26 weeks after implantation. The result were as follows In 6 weeks after implantation of lathed titanium rods, inflammatory reactions, such as minimal degree infiltration of polymorphonuclear leukocytes and lymphocytes were observed in all cases. This was thought to be caused by surgical trauma. However, inflammatory cell infiltration was not seen after implantation of polished and finished rods in all cases. The cellular infiltration and the histologic reaction of the bone after implantation of lathed group were significantly more pronounced than those after implantation of the finished group. In 12 weekt after implantation of lathed rods, two of four cases revealed a minimal degree of cellular infiliration and histologic reaction seemed to be more pronounced in the lathed group, but they were not significant statistically.

PURPOSE: Autologous vein graft is the most commonly used conduit for surgical revascularization of the small and medium sized vessels of the coronary and lower extremity circulations. But, 30~50% of these grafts succumb eventually to occlusive failure, often with recurrent morbidity that necessitates reoperation. The cause of failure is the vein graft atherosclerosis from the neointimal hyperplasia, which is the arterial remodeling process through adaptive thickening of the vein wall in response to the increased wall stress. We try to use cis-platin, DNA binding cell cycle specific inhibitory agent, against neointimal hyperplasia in experimental model. METHOD: 5 korean dogs had a autologous vein graft interposition at femoral or carotid arteries using saphenous or jugular veins bilaterally. One side of pairs is treated with cis-platin for one hour (study), while the other is not (conrol). After 4 weeks, we explanted 6 pairs of vein graft (3 jugular veins and 3 saphenous veins), and measured intimal thickness, intimal area and luminal area using videomorphometry, and analysed intimal ratio and luminal ratio. RESULT: Treatment with cis-platin reduced intimal thickness by 44% (P=0.0118) and intimal area by 50% (P=0.0124). Intimal ratio was decreased in the study group when compared to the control group by 0.18 versus 0.66 (P=0.001). The luminal area of the treated grafts was significantly larger than controls, having increased by 823% (P=0.0307), and luminal ratio having increased by 0.82 versus 0.34 (P=0.001). CONCLUSION: These results suggest that cis-platin reduced the development of neointimal hyperplasia in experimental vein grafts. In order to prove the obtained results to a higher degree, an accumulation of further cases is necessary.

STUDY DESIGN: Retrospective study of date collected prospectively.OBJECTIVES: To report analytic results about association factors related to effect of conservative treatment in surgically indicated single level lumbar spinal stenosis patient.SUMMARY OF LITERATURE REVIEW: There have been various reports about clinical outcomes and relative factors after surgical treatment of spinal stenosis. However, there are few reports about factors related to effect of conservative treatment in surgically indicated lumbar spinal stenosis patient.MATERIALS AND METHODS: We based on 40 patients who had visited our hospital from May 2010 to April 2016 who were traceable for at least three years. We analysed 20 patients who improved symptom and who didn't improved symptom then investigated association factors related to effect of conservative treatment. Clinical assessment was conducted using questionnaire and spinal canal's area and muscle amount were measured in the MRI.RESULTS: Average of the spinal canal of not-improved group is 91.29(±34.26) mm², improved group is 130.70 (±32.18) mm² and impoved group is wider (p=0.001). Muscle mass of improved group is 91.47(±9.43) cm², not-improved group is 79.26 (±14.35) cm², and improved group is wider (p=0.003). Repetitive strain and traffic accident were related in not-improved group (p=0.028). However, practiced stretching continuously were related to symptom improvement (p=0.022).CONCLUSIONS: Association factors related to effect of conservative treatment are cases of wide spinal canal, wide muscle amount, repetitive sprain, traffic accident and stretching. A small muscle amount can be considered as a key factor related to surgical conversion.

Treatment methods of mandibular condylar fracture were conservative and surgical method. Surgical method of mandibular high condylar fracture was very difficult because approach and internal fixation of small size fracture fragment were difficult. So there is a tendency to select conservative method over surgical method for guiding a stable occlusion and avoiding TMJ disorder and growth disturbance, minimizing pain and deviation during function. But, in case of mandibular high condylar fracture patient who has no biting teeth on posterior teeth area, guiding a stable occlusion and conservative functional treatment were very difficult. In this case, patient was 62years old male. He had fracture of mandibular symphysis, right mandibular body, left mandibular high condyle. We treated the patient for mandibular symphysis and right mandibular body fracture area with surgical method. But left mandibular high condylar fracture area was difficult to treat with surgical method. So we selected a conservative functional method on left mandibular high condylar fracture area. We intended recovery of vertical dimension and stable occlusion with implantation of immediate provisional implant on maxillar and mandibular posterior teeth area, and temporary crown. And then patient did mandibular functional movement and his mandibular function was recoverd.

PURPOSE: In about 1% of cases, incidental gallbladder cancers (iGBC) are found after routine cholecystectomy. The aim of this study is to compare clinical features of iGBC with benign GB disease and to evaluate factors affecting recurrence and survival. METHODS: Between January 1998 and March 2014, 4,629 patients received cholecystectomy and 73 iGBC patients (1.6%) were identified. We compared clinical features of 4,556 benign GB disease patients with 73 iGBC patients, and evaluated operative outcomes and prognostic factors in 56 eligible patients. RESULTS: The iGBC patients were older and concomitant diseases such as hypertension and anemia were more common than benign ones. And an age of more than 65 years was the only risk factor of iGBC. Adverse prognostic factors affecting patients' survival were age over 65, advanced histology, lymph node metastasis, and lymphovascular invasion on multivariate analysis. Age over 65 years, lymph node involvement, and lymphovascular invasion were identified as unfavorable factors affecting survival in subgroup analysis of extended cholecystectomy with bile duct resection (EC with BDR, n = 22). CONCLUSION: Prior to routine cholecystectomy, incidental GB cancer should be suspected especially in elderly patients. And advanced age, lymph node metastasis, and lymphovascular invasion are important prognostic factors in EC with BDR cohorts.
