Since Ender introduced the concepts of multiple flexible intramedullary nailing in 1970, Ender nailing has been mostly used in intertrochanteric fractures of the elderly patients, but it has been rarely used in younger patients because of serious complications such as shortening and external rotation deformity. Authors already contended that the incidence of such complications had intimate connection with the quality of bone, and accordingly with the age. To substantiate the contention, we analyzed thirty-four cases with more than one year follow-up among forty cases of intertrochanteric fractures treated with Ender nails during the period from 1982 to 1989. And the results are summarized as follows;1. The average age was 39 yrs., and the most common cause of fractures was fall from a height. 2. According to the Kyle et al. clsssification, stable fractures(type I & II ) were 13 cases(38%), and unstable fractures (type III & IV) were 21 cases(62%). 3. According to the Singh's index, the good in bone quality(Grade 4, 5, & 6) were 31 cases(91 %), and the poor(Grade 1, 2, & 3) were only 3 cases(9%). 4. Postoperative complications occurred in 6 cases(17%), which included ROM limitation of knee joint in three cases(9%), proximal migrations of nails in two(5%), and distal migrations of nails in one(3%). Among them, 4 cases required revisional operations. There was no case with apparent external rotation deformity over 20 and shortening over 2cm. 5. It is thought that, contradictory to common beliefs, Ender nailingis a safe method for intertrochanteric fractures of femur in younger patients with good bone quality, but requires some experiences and cautions to prevent such complications as external rotation deformity and shorterning.

Even the antituberculous drugs could cure the disease itself, it might not prevent progressive kyphosis and its sequelae. Therefore, radical curettage and anterior arthrodesis with autogenous strut bone graft has been used to prevent this deformity. From May 1982 to May 1989, twenty four cases of spinal tuberculosis treated with anterior arthrodesis were analysed about the progression of postoperative kyphosis. These cases were followed up for more than 1 year at least, and the following results were obtained; 1. Lumbar spine was most commonly involved. There was involvement of one disc space in 12 cases, only narrowing of disc space in 7 cases, and two disc spaces in 5 cases. 2. The degree of vertebral loss was under 1 in 15 cases, 0 (disc space narrowing only) in 7 cases, and over 1 in 2 cases. 3. Compared with immediate postoperative kyphotic angle, there was increase of kyphotic angle in 15 cases but most of them were under 10 degress. 4. Preoperative degree of vertebral loss of 15 incerased cases was 0.5 and that of 9 decreased of maintained cases was 0.2 in average. 5. Preoperative vertebral involvement of 15 increased cases was 1.3 and that of 9 decreased or maintained cases was 1.2 in average.

The authors experienced a case of early fracture of an alumina ceramic liner after ceramic-on-ceramic total hip arthroplasty, without any history of trauma. A 47-year-old male visited our center, due to a sudden crunching sound from the right hip at three weeks, after a ceramic-on-ceramic total hip arthroplasty for the osteonecrosis of right femoral head. Plain radiographs revealed multiple radio-opaque fragments around the displaced neck of the femoral stem. There were severely comminuted fracture of the ceramic liner with slight black staining of the surrounding tissue, and even damaged the surface of the ceramic head, on the operative field. The fractured liner and a damaged head were replaced with a new ceramic liner and head, after the removal of the fractured ceramic fragments, as completely as possible. Careful follow up with a caution for early ceramic liner fracture should be required in ceramic-on-ceramic total hip arthroplasty.

PURPOSE: This study examined the effects of beraprost sodium on digital infrared thermal images in patients with peripheral arterial disease caused by type 2 diabetes mellitus. MATERIALS AND METHODS: Twenty-five diabetic patients with peripheral arterial disease were treated with beraprost sodium in a prospective, multicenter, cohort study from February 2013 to December 2014. Beraprost sodium (40 μg) was administered orally 3 times daily (120 μg/day) for 6 months. The visual analogue scale (VAS) and digital infrared thermal imaging (DITI) were performed to compare the blood flow improvement between before and after dosing. RESULTS: Among the 25 patients included in the evaluation, 22 patients completed the study. A significant increase in body temperature was observed in the front and left side, particularly in the plantar side in DITI compared to that before and after administration. An increase in body temperature was observed at the frontal part from 28.1℃±2.3℃ to 29.1℃±2.1℃ (p=0.021), at the left side from 27.8℃±2.4℃ to 28.6℃±1.9℃ (p=0.028), at the plantar part at 24.0℃±1.5℃, and at the plantar part at 27.1℃±2.4℃ (p < 0.01). The VAS decreased significantly from 5.4±1.3 to 2.7±2.0 after 6 months of treatment (p < 0.01). CONCLUSION: Beraprost sodium is a safe and easy-to use oral medication for diabetes peripheral arterial disease. It can be expected to increase the blood flow and decrease the lower extremity pain statistically after being taken for 6 months.

A 73-year-old male was admitted for unhealed wound. Eight months ago, the patient had been operated for excision of soft tissue mass on left distal thigh area in previous hospital and after 4 months from first operation, had been reoperated because of recurrence. The pathologic diagnosis of previous operation was simple cyst. In operating finding, the mass invaded the vastus lateralis fascia and had irregular margin and adhesion. We carried out simple excision with retaining 5 cm of free margin from the mass. The pathologic diagnosis of our hospital was malignant fibrous histiocytoma, and then the patient was performed radiation therapy. In 1 year follow-up, there was no significant finding either increasing mass size or metastasis. We misdiagnosed as simple cyst and then performed simple excision, however finally pathologic diagnosis confirmed as malignant fibrous histiocytoma. It is considered to operate a mass that preoperative proper evaluation and diagnosis are required.

OBJECTIVES:
To evaluate the radiological outcomes of direct lateral lumbar interbody fusion (DLIF).SUMMARY OF LITERATURE REVIEW: DLIF, as a minimally invasive spinal surgical procedure, is useful for degenerative spinal diseases. However, few reports have evaluated the clinical and radiological outcomes of DLIF in Korea.
MATERIALS AND METHODS:
We analyzed 44 patients who underwent DLIF at our hospital from September 2015 to September 2017. Of these patients, 89 segments were included in this study. We measured preoperative and postoperative radiological values including the disc height, central canal area, height of the foramen, and segmental sagittal angle on magnetic resonance imaging. We also measured patients' visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores as clinical parameters.
RESULTS:
Statistically significant improvements were found in the height of the left and right foramina (20.8% and 25.6%, respectively), the height of the intervertebral discs (86.0% and 84.3%, respectively), the cross-sectional area of the central nervous system (33.1%), lumbar lordosis, and the lumbar segmental angle (2.7° and 8.7°, respectively) after surgery. The VAS and ODI scores also showed significant improvements (65.7% and 67.7%, respectively) when compared with the preoperative level.
CONCLUSIONS
DLIF was found to be effective for the treatment of diseases such as foraminal stenosis, degenerative spondylolisthesis, and adjacent segment diseases through indirect neuro-decompression of the bilateral foramina and central vertebrae.

Sclerotium rot was found on Cymbidium orchids at Seosan-si, Chungcheongnam-do, Korea, in July, 2010. Symptoms occurred on low leaves, which turned yellowish, after which the entire plant wilted. Severely infected plants were blighted and eventually died. White mycelial mats and sclerotia appeared on pseudobulbs. Based on the mycological characteristics and pathogenicity, the causal fungus was identified as Sclerotium rolfsii. This is the first report of new Sclerotium rot on Cymbidium spp. caused by S. rolfsii in Korea.

Journal of Korean Medical Science 2022;37(13):e105-
Background:
Many studies have reported that minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) provides satisfactory treatment comparable to other fusion methods. However, in the case of MI-TLIF, there are concerns about the long-term outcome compared to conventional bilateral PLIF due to the small amount of disc removal and the lack of autogenous bone graft. Long-term follow-up studies are still lacking as most of the previous reports have follow-up periods of up to 5 years.
Methods:
Thirty patients who underwent MI-TLIF were followed up for > 10 years (mean, 11.1 years). Interbody fusion rates were determined using a modified Bridwell grading system.Adjacent segment disease (ASD) was defined as radiological adjacent segment degeneration (R-ASDeg) as seen on plain X-rays; reoperated adjacent segment disease referred to the subsequent need for revision surgery. Clinical outcomes after surgery were assessed based on back and leg pain as well as the Oswestry disability index (ODI).
Results:
The overall radiological fusion rate, at the 1-, 5-, and 10-year follow-up was 77.1%, 91.4%, and 94.3%, respectively. The incidence of R-ASDeg 1, 5, and 10 years after surgery was 6.7%, 16.7%, and 43.3% at the proximal adjacent segment and 4.8%, 14.3%, and 28.6% at the distal adjacent segment, respectively. R-ASDeg at either the proximal or distal segment was determined in 50.0% of the patients 10 years postoperatively. All clinical parameters improved significantly during follow-up, although the ODI and the visual analog scale (VAS) for leg pain at the 10-year follow-up were significantly worse in the R-ASDeg group than in the other patients (P = 0.009, P = 0.040).
Conclusion
MI-TLIF improved both clinical and radiological outcomes, and the improvements were maintained for up to 10 years after surgery. However, R-ASDeg developed in up to 50% of the patients within 10 years, and both leg pain on the VAS and the ODI were worse in patients with R-ASDeg.

Objectives:
. The relationships among positional obstructive sleep apnea (POSA), obstructive sleep apnea (OSA), and periodic limb movements during sleep (PLMS) remain unclear. We investigated these relationships with respect to the severity of OSA and explored the underlying mechanisms.
Methods:
. We retrospectively reviewed 6,140 eligible participants who underwent full-night diagnostic polysomnography at four clinical centers over a 5-year period, utilizing event-synchronized analysis. We evaluated the periodic limb movement index (PLMI) and the periodic limb movement with arousal index (PLMAI). The impacts of POSA on the PLMI, PLMAI, and PLMS were analyzed in relation to the severity of OSA.
Results:
. The mean PLMI, the mean PLMAI, and the prevalence of PLMS were significantly lower in participants with severe OSA compared to the mild and moderate OSA groups. The mean PLMI among those with mild OSA exceeded that of control participants. Furthermore, the mean PLMI (4.8±12.7 vs. 2.6±9.8 events/hr, P<0.001), the mean PLMAI (0.9±3.7 vs. 0.5±3.3 events/hr, P<0.001), and the prevalence of PLMS (11% vs. 5.3%, P<0.001) were higher in patients with POSA than in those with non-positional OSA. This PLMS finding was particularly pronounced among those with severe OSA (odds ratio [OR], 1.554; 95% confidence interval [CI], 1.065–2.267) and was less evident in the mild (OR, 0.559; 95% CI, 0.303–1.030) and moderate (OR, 1.822; 95% CI, 0.995–3.339) groups.
Conclusion
. Patients with POSA, especially those with severe OSA, exhibit a comparatively high prevalence of PLMS. In cases involving prominent PLMS, the diagnosis and treatment of POSA and OSA should be considered.
