Purpose:
To analyze the incidence rate and risk factors of intraocular lens dislocation in South Korea from 2002 to 2020 using Health Insurance Review and Assessment Service data.
Methods:
This study included 15% of patients aged > 40 years had pseudophakia or intraocular lens primary implantation codes during 2002-2020 (737,606 patients). The annual incidence rate and risk factors of intraocular lens dislocation during 2002-2020 were analyzed.
Results:
The mean annual incidence rate of intraocular lens dislocation during 2002-2020 was 0.20 ± 0.7%. The annual incidence rate increased significantly from 0.17% in 2002 to 0.34% in 2020 (p < 0.001). The annual mean incidence rate for women was 0.1 ± 0.05%, and there was no increasing trend (p > 0.05). The annual mean incidence rate for men was 0.35 ± 0.13% and an increasing trend was found (p < 0.001). High myopia, uveitis, retinitis pigmentosa, glaucoma, pseudoexfoliative glaucoma and previous vitreoretinal surgery significantly increased the risk of intraocular lens dislocation (p < 0.001). Hemodialysis and hypertension were not significant risk factors (p > 0.05).
Conclusions
The mean annual incidence rate of intraocular lens dislocation in South Korea was 0.2 ± 0.7%, and it showed an increasing trend, among men. High myopia, uveitis, retinitis pigmentosa, glaucoma, pseudoexfoliative glaucoma and previous vitreoretinal surgery significantly increased the risk of intraocular lens dislocation.

PURPOSE: This treatment planning study was undertaken to evaluate the impact of beam angle configuration of intensity-modulated radiotherapy (IMRT) on the dose of the normal liver in hepatocellular carcinoma (HCC). MATERIALS AND METHODS: The computed tomography datasets of 25 patients treated with IMRT for HCC were selected. Two IMRT plans using five beams were made in each patient; beams with equidistance of 72degrees (Plan I), and beams with a 30degrees angle of separation entering the body near the tumor (Plan II). Both plans were generated using the same constraints in each patient. Conformity index (CI), homogeneity index (HI), gamma index, mean dose of the normal liver (Dmean_NL), Dmean_NL difference between the two plans, and percentage normal liver volumes receiving at least 10, 20, and 30 Gy (V10, V20, and V30) were evaluated and compared. RESULTS: Dmean_NL, V10, and V20 were significantly better for Plan II. The Dmean_NL was significantly lower for peripheral (p = 0.001) and central tumors (p = 0.034). Dmean_NL differences between the two plans increased in proportion to gross tumor volume to normal liver volume ratios (p = 0.002). CI, HI, and gamma indices were not significantly different for the two plans. CONCLUSION: The IMRT plan based on beams with narrow separations reduced the irradiated dose of the normal liver, which would allow radiation dose escalation for HCC.

Journal of Nutrition and Health 2018;51(4):307-315
PURPOSE: This study evaluated the effects of personalized nutrition intervention for increasing hospital meal intake by elderly patients with malnutrition. METHODS: The subjects were 30 elderly patients with malnutrition who visited a general hospital located in Daegu. An individual nutrition intervention such as change of meal types or special meal service was given to the patients according to nutrition diagnosis related to inadequate intake of hospital meals. Nutritional intake status of the subjects was assessed by analyzing energy intake, protein intake, index of nutritional quality (INQ), nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR). RESULTS: The causes of inadequate intake in the subjects were poor appetite or preference problems (46.7%), symptom-related problems (30.0%) and mastication problems (23.3%). The INQ of protein in the subjects was significantly increased from 0.81 ±0.17 to 1.41 ±0.25 after the nutrition intervention (p < 0.05). The NAR of protein (before 0.50 ±0.21, after 0.58 ±0.17), iron (before 0.72 ±0.30, after 0.84 ±0.29) and vitamin B2 (before 0.31 ±0.16, after 0.37 ±0.14) was also increased after the nutrition intervention (p < 0.05). The MAR of five nutrients, protein, calcium, iron, vitamin A and vitamin B2, was significantly increased by the nutrition intervention (p < 0.05). CONCLUSION: Personalized nutrition intervention according to nutrition diagnosis related to inadequate intake of hospital meals may improve the intake amount of elderly patients with malnutrition.

OBJECTIVES: To determine changes in the incidence and pattern of eclampsia in Il Sin Christian Hospital over a 46-year period. METHODS: Information was collected from medical records of the 1910 eclamptic patients among 233,613 deliveries in Il Sin Christian Hospital from Jan. 1 1953 to Dec. 31 1998. Incidence, presentation, and management of eclampsia were reviewed retrospectively, and maternal mortality rate and perinatal mortality rate were calculated. Statistical analysis was done by Chi-squared and Fisher's exact test through two by two tables looking at relative changes between each study period. RESULTS: The overall incidence of eclampsia was 81.8 per 10,000 deliveries. The incidence of eclampsia had increased from 137.3/10,000 in 1953-1962 to 278.4/10,000 in 1963-1972, but the rate had reduced to 6.5/10,000 in 1993-1998. There was a statistically significant fall in the rate of eclampsia every decade between 1973 and 1992, but there has been steady decrease in the last study period. Convulsion occurred antepartum in 54% of patients, intrapartum in 29% and postpartum in 17%. With the reduction in the proportion of antepartum eclampsia, there has been a relative increase in that of intrapartum and postpartum eclampsia. Maternal death occurred in 59 cases among eclampsia, and maternal mortality rate was 3.1%. Maternal mortality rate had significantly decresed from 11.1% in 1953-1962 to 3.8% in 1963-1972, and there has been no maternal death from eclampsia since 1986. Postpartum eclampsia had increased death risk compared with antepartum or intrapartum eclampsia. There were 280 cases of perinatal death and overall perinatal mortality rate was 144.1 per 1000 deliveries. There was a significant decrease in the rate from 243.2/1000 in 1953-1962 to 141.5/1000 in 1963-1972, but the rate has risen steadily since 1983. CONCLUSIONS: With the improvement in antenatal care and management of eclampsia, the incidence of eclampsia and its associated maternal mortality has decreased over the last 46 years. But eclampsia still remains a significant complication of pregnancy with high maternal and perinatal mortality.

Although many methods have been developed to correct the aging process of the head and neck, the correction of nasolabial folds still remains a difficult area. The difficulty of correcting nasolabial fold is due to the anatomical location and the difference of aging process. From March 2000 to February 2001, the authors operated on 10 aging face patients using face lift with SMAS and FAME(Finger-assisted malar fat pad elevation) technique. The authors repositioned the SMAS-platysma flap posterosuperiorly and used finger dissection of the malar fat pad enabling a 3-dimensional correction and repositioning of the fat pad without detachment of the zygomatic ligament. The finger dissection of the malar fat pad attached to the skin enables a more anatomical correction of the malar fat pad with a more natural looking layer and longer lasting results in addition to decreased hematoma, edema and postoperative pain compared to previous methods.

OBJECTIVES: Homocysteine has been associated with cognitive impairment and various psychiatric symptoms. This study was designed to examine the relationship exists between plasma homocysteine concentration and behavioral and psychological symptoms of dementia(BPSD). METHODS: 41 subjects with dementia of Alzheimer's type were included in this study. We carried out history taking, physical examination, and cognitive assessment for the diagnosis of dementia of Alzheimer's type based on DSM-IV. We scored the Mini Mental State Examination(MMSE), Global Deterioration Scale(GDS), Clinical Dementia Rating(CDR), and the Korean Neuropsychiatric Inventory(K-NPI). We also measured levels of homocysteine, folate, and vitamin B12 in the plasma. RESULTS: We found statistically significant positive correlations between homocysteine concentration with NPI total score, and with scores of several sub-domains such as delusion, agitation/aggression, depression/dysphoria, and elation/euphoria. No significant correlation existed between homocysteine levels and scores of MMSE, GDS, and CDR. CONCLUSIONS: This study shows that plasma homocysteine levels are associated with BPSD. Further research is necessary to identify pathophysiologic mechanisms underlying these relationships.

OBJECTIVETo explore mid-term follow up results of distal fixation prosthesis in treating unstable intertrochanteric fractures in elderly patients.
METHODSFrom May 2008 to March 2014,58 elderly patients with unstable intertrochanteric were treated with distal fixation prosthesis, among them, there were 15 males and 43 females aged from 75 to 87 years old with an average of 83.2 years old. Fracture were classified according to Evans classification, 39 cases were type I c and 19 cases were type I d. Surgical risk was evaluated before operation, 9 patients were performed total hip arthroplasty and 49 patients were performed prosthetic replacement hip joint function of patients with different age period, Evans classificaton, prothesis type, fixation method were evaluated respectively by using Harris score.
RESULTSFifty-six patients were followed up from 13 to 36 months with an average of 21.6 months. Harris score was 83.51 ± 6.40, 5 cases got excellent results, 38 cases good and 13 cases moderate. Harris score of patients aged from 75 to 80 years old was 88.64 ± 2.35, 81.64 ± 6.40 in patients aged more than 80 years old, and had significant differences between two groups; Harris score in patients with type Evans I c was 83.64 ± 6.53, and 83.11 ± 6.08 in type Evans I d, while there was no significant differences between two groups. There was no obvious meaning in Harris score between patients with tension band (83.63 ± 6.15) and without tension band (82.41 ± 6.57). There was no significant meaning in Harris score between patients with normal distal fixation prosthesis (83.34 ± 6.43) and femoral moment reconstruction distal fixation prosthesis (83.92 ± 6.51). There was 1 patient occurred hip joint dislocation on the operative side and re-dislocation after manual reduction, then received open reduction. Two patients occurred femoral osteolysis without clinical symptoms, and treated conservative treatment.
CONCLUSIONArtificial joint replacement for unstable intertrochanteric fractures in elderly patients, hip joint function in patients aged more than 80 years old is worse, while there was no obvious market effect in fracture classification, whether to use tension band and type of distal fixation prosthesis, moreover, proximal femoral osteolysis should be focused on.

OBJECTIVETo investigate the clinical effects of anterior cervical intervertebral space decompression under microscope in treating cervical spondylotic myelopathy in elderly patients.
METHODSFrom June 2009 to March 2012, 43 patients with cervical spondylotic myelopathy were treated with anterior cervical intervertebral space decompression and intervertebral fusion under microscope. There were 26 males and 17 females, aged from 60 to 72 years old with an average of (64.9±3.7) years. Japanese Orthopaedic Association System (JOA) score was from 7 to 12 points with an average of (9.5±1.8) points before operation. The function of nerves was assessed before and after operation according to JOA.
RESULTSAll patients were followed up from 10 to 18 months with an average of (14.7±1.6) months. Postoperative JOA score was (13.81±1.44) points (ranged, 10 to 16), had significantly higher than preoperative (P<0.01). According to the rate of the improved JOA score, 9 cases got excellent results, 26 good, 7 fair, 1 poor.
CONCLUSIONAnterior cervical intervertebral space decompression under microscope for cervical spondylotic myelopathy in elderly patients is safe and effective.
