OBJECTIVES: Depression, sleep complaints and cognitive impairments are commonly observed in the elderly. Elderly subjects with depressive symptoms have been found to show both poor cognitive performances and sleep disturbances. However, the relationship between sleep complaints and cognitive dysfunction in elderly depression is not clear. The aim of this study is to identify the association between sleep disturbances and cognitive decline in late-life depression. METHODS: A total of 282 elderly people who underwent nocturnal polysomnography in a sleep laboratory were enrolled in the study. The Korean version of the Neuropsychological Assessment Battery developed by the Consortium to Establish a Registry for Alzheimer's Disease (CERAD-K) was applied to evaluate cognitive function. Depressive symptoms were assessed with the geriatric depression scale (GDS) and subjective sleep quality was measured using the Pittsburg sleep quality index (PSQI). RESULTS: The control group (GDS< or =9) when compared with mild (10< or =GDS< or =16) and severe (17< or =GDS) depression groups, had significantly different scores in the Trail making test part B (TMT-B), Benton visual retention test part A (BVRT-A), and Stroop color and word test (SCWT)(all tests p<0.05). The PSQI score, REM sleep duration, apnea-hypopnea index and oxygen desaturation index were significantly different across the three groups (all indices, p<0.05). A stepwise multiple regression model showed that educational level, age and GDS score were predictive for both TMT-B time (adjusted R2=35.6%, p<0.001) and BVRT-A score (adjusted R2=28.3%, p<0.001). SCWT score was predicted by educational level, age, apnea-hypopnea index (AHI) and GDS score (adjusted R2=20.6%, p<0.001). Poor sleep quality and sleep structure alterations observed in depression did not have any significant effects on cognitive deterioration. CONCLUSION: Older adults with depressive symptoms showed mild sleep alterations and poor cognitive performances. However, we found no association between sleep disturbances (except sleep apnea) and cognitive difficulties in elderly subjects with depressive symptoms. It is possible that the impact of sleep disruptions on cognitive abilities was hindered by the confounding effect of age, education and depressive symptoms.

After dual plating with a locking compression plate for comminuted intraarticular fractures of the distal humerus, the incidence of ulnar nerve injury after surgery has been reported to be up to 38%. This can be reduced by an anterior transposition of the ulnar nerve but some surgeons believe that extensive handling of the nerve with transposition can increase the risk of an ulnar nerve dysfunction. This paper reports ulnar nerve injuries caused by the incomplete insertion of a screw head in dual plating without an anterior ulnar nerve transposition for AO/OTA type C2 distal humerus fractures. When an anatomical locking plate is applied to a distal humeral fracture, locking screws around the ulnar nerve should be inserted fully without protrusion of the screw because an incompletely inserted screw can cause irritation or injury to the ulnar nerve because the screw head in the locking system usually has a slightly sharp edge because screw head has threads. If the change in insertion angle and resulting protruded head of the screw are unavoidable for firm fixation of fracture, the anterior transposition of the ulnar nerve is recommended over a soft tissue shield.

Fractures of the acetabulum are relatively uncommon. But if fractures of the acetubulum are not accurately evaluated, classified, and reduced anatomically, major sequalae and complications are frequently developed. Because of complicated anatomy, difficulty with surgical exposure, severe comminution, and major associated injuries, the treatment of displaced acetabular fractures between conservative and operative methods is still controversial. We reviewed thirty five cases of displaced acetabular fracture treated operaively from January 1984 to December 1991. The prevalent age was the fourth decade. There was twenty seven cases of associated injuries, twenty two dislocations of the hip. According to the Letournel's classification, the most common fracture type was posterior wall and both column type. The fracture was fixed internally with only screws in thirteen cases and with plate and screws in twenty two cases. Among thirty five patients, five patients were lost in the follow up and another five patients had followed up lesser than one year. The mean duration of follow-up afrer the operation was three years (range, one to eight years). Among twenty five patients who had followed up more than one year, the satisfactory results were achieved in nineteen patients (76%) and the poor results were achieved in three patients (8%). The complications were post-traumatic arthritis, avascular necrosis of femoral head, osteomyelitis in iliac bone, skin necrosis, and heterotopic ossification.

Background:
Recognizing the seriousness of the misuse and abuse of medical narcotics, the South Korean government introduced the world's first narcotic management system, the Narcotics Information Management System (NIMS). This study aimed to explore the recent one-year opioid prescribing patterns in South Korea using the NIMS database.
Methods:
This study analyzed opioid prescription records in South Korea for the year 2022, utilizing the dispensing/ administration dataset provided by NIMS. Public data from the Korean Statistical Information Service were also utilized to explore prescription trends over the past four years. The examination covered 16 different opioid analgesics, assessed by the total number of units prescribed based on routes of administration, type of institutions, and patients’ sex and age group. Additionally, the disposal rate for each ingredient was computed.
Results:
In total, 206,941 records of 87,792,968 opioid analgesic units were analyzed. Recently, the overall quantity of prescribed opioid analgesic units has remained relatively stable. The most prescribed ingredient was oral oxycodone, followed by tapentadol and sublingual fentanyl. Tertiary hospitals had the highest number of dispensed units (49.4%), followed by community pharmacies (40.2%). The highest number of prescribed units was attributed to male patients in their 60s. The disposal rates of the oral and transdermal formulations were less than 0.1%.
Conclusions
Opioid prescription in South Korea features a high proportion of oral formulations, tertiary hospital administration, pharmacy dispensing, and elderly patients. Sustained education and surveillance of patients and healthcare providers is required.

BACKGROUNDS/AIMS: Prognostic factors for colorectal cancer with hepatic metastasis are not well-established. We investigated the factors that predicted survival following surgical resection of hepatic metastases in patients with colorectal cancer. METHODS: Fifty-three patients underwent resection of hepatic metastases of colorectal cancer between January 2000 and December 2005, with follow-up periods that ranged from 3 to 119 months. In this retrospective study, the effects of sex, age, type of hepatic resection, T stage and N stage of the primary cancer, number and size of metastatic hepatic tumors, synchronicity or metachronicity of the liver metastases, surgical resection margins, and preoperative carcinoembryonic antigen (CEA) levels on 1-year and 3-year survival were analyzed using the Kaplan-Meier method and the log rank test. RESULTS: Median survival was 39.9 months and the 3-year survival rate was 62.2%. Twenty patients died during the follow-up period of 3 to 119 months (mean, 48.8+/-34.24). In univariate analysis, only the surgical margin of the hepatic metastasis resection correlated significantly with 3-year survival. Sex, age, T stage and N stage of the primary cancer, synchronicity or metachronicity of the metastases, number and size of hepatic metastases, type of hepatic resection and preoperative CEA levels did not predict long-term outcome. CONCLUSIONS: Hepatic resection provides a safe and effective treatment in patients with hepatic metastasis from colorectal cancer. In this study, only the surgical resection margin of the hepatic metastasis of colorectal cancer significantly predicted survival.

9.A Case of Bilateral Dacryocystocele with Absence of the Lacrimal Puncta.
Journal of the Korean Ophthalmological Society 1990;31(1):81-85
A 33-year-old female suffered from bilateral mass in the medial area and epiphora for 20 years. The mass recurred after incomplete removal several times. Ocular examination showed that the puncta and papillae of the both lower and upper lids were completely missing. At operation, there was obstruction in the bony portion of the nasolacrimal duct. The mass was a distended lacrimal sac. The lacrimal sac and the mucosa of the nasolacrimal duct were compJetely excised in the right side. The excision of lacrimal sac and mucosa of the nasolacrimal duct and conjunctivo-rhinostomy using Jones tube were performed in the left side. Nine months after operation, the patient was happy with the results and there was no recurrence.
