Purpose:
The purpose of this study is to analyze the clinical results of patients with basicervical fractureundergoing cephalomedullary nailing (CMN) with an additional cannulated screw fixation compared to only performing CMN. We hypothesized that a difference may exist in the clinical outcomes if an ad-ditional screw is fixed with CMN compared to only performing CMN in basicervical fracture.
Materials and Methods:
A total of 28 consecutive patients who underwent CMN for basicervical fracture were included. In 9 cases, only CMN was conducted, and in 19 cases, an additional cannulated screw fixation was performed with CMN. Bone union, sliding distance, reduction status, and fixation failure were evaluated by postoperative radiography, and ambulatory ability was evaluated by functional results. These findings were compared between a group of CMN and a group of CMN with an additional cannulated screw.
Results:
There were 4 males and 24 females with a mean age of 84 years (range, 69–100 years). No significant difference was found in postoperative reduction, tip-apex distance, bone union, and walking function recovery after surgery between the two groups, but in the sliding distance of the lag screw, the CMN group demonstrated more sliding (6.2 mm [range, 2.5–13.4 mm] vs 3.5 mm [range, 0.1– 9.2 mm]; p=0.045). Among the two groups, only one case of fixation failure at the postoperative four months was observed in the CMN group (p=0.321), and hemiarthroplasty with nail construct removal was performed.
Conclusion
CMN with additional cannulated screw fixation is a safe and reliable surgical option in basicervical fracture. It provided favorable clinical outcomes and may be a good alternative for treating basicervical fracture.
2.Hip Fractures in the Elderly: Perioperative Management and Prevention of Medical Complications
Journal of the Korean Fracture Society 2023;36(1):39-44
Elderly patients with hip fractures are at an increased risk of developing medical complications with higher mortality rates. Most patients require surgical treatment, and an early surgical intervention can reduce complications and lower mortality risk. A restrictive red blood cell transfusion strategy is usually applied, and the amount of transfusion can be reduced through medications such as tranexamic acid. Delirium can be prevented using non-pharmacological methods. In addition, it is necessary to prevent venous thromboembolism through mechanical or chemical prophylaxis. A multidisciplinary approach using the ERAS (Enhanced Recovery After Surgery) protocol and orthogeriatric care can help to reduce medical complications and mortality.
3.Management of Polytrauma
The Journal of the Korean Orthopaedic Association 2018;53(1):1-8
To optimize results for polytrauma patients, prompt evacuation and early management are critical. These patients also require a multidisciplinary team effort, involving multiple departments, as they are likely to have not only musculoskeletal injuries but also specific organ injuries or compromised general status. In the 1980s, the goal was definitive fracture fixation in the early stages after injury (early total care). Since the 1990s, however, the goal has shifted to temporary fixation, with a delay of several days prior to definitive fixation (damage control orthopedics). Recently, the timing and extent of treatment have been determined by the condition of patients based on objective indicators. Because surgery may result in secondary damage, it is desirable to minimize potential tissue injury with either temporary fixation or a delay in definitive fixation.

PURPOSE: Cephalomedullary nails (CMN) are commonly used for the surgical treatment of intertrochanteric fractures. This study aimed to evaluate overall postoperative local complications by reviewing patients who received surgical treatment using three different types of implants. MATERIALS AND METHODS: The study sample included 353 patients (107 males, 246 females) who underwent surgery using CMN for intertrochanteric fractures. Three different types of implants were used: i) the Gamma3® (Stryker) in 80 cases, ii) the Targon® PF (Aesculap) in 225 cases, and iii) the Compression Hip Nail® (Trademedics) in 48 cases. The mean age was 82.6 (range, 60–109) years and the average follow-up period was 15 (range, 6–80) months. Postoperative local complications and risk factors of cut-out were assessed. RESULTS: The most common complication was cut-out (n=26). Other complications included non-union (n=3), periprosthetic fracture (n=2), avascular necrosis (n=1), heterotopic ossification (n=1), and sleeve pull out (n=1). Multivariate analysis revealed that the cut-out group had a higher rate of poor reduction compared to the non-complicated group (P < 0.001). Although the mean tip-apex distance (TAD) was 18.4 mm in the non-complicated group, lower than that of the cut-out group (P=0.001), multivariate analysis revealed that TAD was not a significant risk factor for cut-out (P=0.065). CONCLUSION: Cut-out is the most common local complication associated with surgical treatment of intertrochanteric fractures using CMN. Proper reduction appears to be important in lowering the risk of cut-out. Maintaining low TAD is another critical factor in achieving sufficient fixation of lag screw to the subchondral bone of the femoral head.

Choroidal osteoma is a benign ossified tumor that is found predominantly in healthy young women during their second and third decades of life. The lesions are white-to-cream or orange in color, are located in the peripapillary and macular areas, and are unilateral in most patients. The symptoms of choroidal osteoma include decreased visual acuity and metamorphopsia or scotoma corresponding to the location of the osteoma, but some patients have no symptoms. Prognosis of vision varies according to tumor location, retinal pigment epithelial and sensory retinal degeneration, subretinal fluid and hemorrhage, and development of a subretinal neovascular membrane.

BACKGROUND/AIMS: Fabry disease is an X-linked recessive and progressive disease caused by alpha-galactosidase A (alpha-GaL A) deficiency. We sought to assess the prevalence of unrecognized Fabry disease in dialysis-dependent patients and the efficacy of serum globotriaosylceramide (GL3) screening. METHODS: A total of 480 patients of 1,230 patients among 17 clinics were enrolled. Serum GL3 levels were measured by tandem mass spectrometry. Additionally, we studied the association between increased GL3 levels and cardiovascular disease, cerebrovascular disease, or left ventricular hypertrophy. RESULTS: Twenty-nine patients had elevated serum GL3 levels. The alpha-GaL A activity was determined for the 26 patients with high GL3 levels. The mean alpha-GaL A activity was 64.6 nmol/hr/mg (reference range, 45 to 85), and no patient was identified with decreased alpha-GaL A activity. Among the group with high GL3 levels, 15 women had a alpha-GaL A genetics analysis. No point mutations were discovered among the women with high GL3 levels. No correlation was observed between serum GL3 levels and alpha-GaL A activity; the Pearson correlation coefficient was 0.01352 (p = 0.9478). No significant correlation was observed between increased GL3 levels and the frequency of cardiovascular disease or cerebrovascular disease. CONCLUSIONS: Fabry disease is very rare disease in patients with end-stage renal disease. Serum GL3 measurements as a screening method for Fabry disease showed a high false-positive rate. Thus, serum GL3 levels determined by tandem mass spectrometry may not be useful as a screening method for Fabry disease in patients with end stage renal disease.

BACKGROUND: Type 2 diabetes develops because of defects in both insulin secretion and action. The half-life of insulin in uremia is prolonged because the metabolic clearance rate of insulin in diabetic end stage renal disease (ESRD) patients is reduced with consequence that the dose of insulin and/or oral hypoglycemic agent (OHA) administered in normal renal function make them increase the risk of hypoglycemia. Therefore, we should usually reduce the dose of insulin and/or OHA, or stop administration of insulin and/or OHA if type 2 diabetic patients are progressed to ESRD. But in some patients, that is not true. The aim of this study was to test the hypothesis that insulin resistance plays an important role in (re)evaluation of optimal insulin and/or OHA dose for glycemic control after type 2 diabetic patients are progressed to ESRD. METHODS: Insulin resistance was examined in 23 type 2 diabetic ESRD patients with tight control of glycemia using the K index of the insulin tolerance test (Kitt). We divided 23 patients into three groups. Group 1 (n=10) was defined as patients who were administered neither insulin nor OHA after ESRD. Group 2 (n=9) was defined as patients who were changed from insulin to OHA as drug for glycemic control after ESRD. Group 3 (n=4) was defined as patients in whom insulin or OHA was continuously administered after ESRD without a change of them for glycemic control. We compared the degree of insulin resistance among these three groups. RESULTS: Insulin resistance determined by Kitt was significantly different between group 1 (Kitt, 2.1422/0.94-4.01%/min), group 2 (Kitt, 1.3811/0.79- 3.90%/min) and group 3 (Kitt, 0.8550/0.44-1.81%/min) by using Kruskal-Wallis test (p=0.048). Kitt in group 3 was significantly lower than in group 1 by using Mann-Whitney test (p=0.016). CONCLUSION: Although metabolic clearance of insulin is reduced by renal failure, demand of insulin/ OHA for optimal glycemic control is not reduced in higher insulin-resistant type 2 diabetic ESRD patients on hemodialysis. Insulin resistance plays an important role in determination of optimal insulin/ OHA dose for glycemic control after type 2 diabetic patients are progressed to ESRD.

Theophylline has been used for more than 50 years to treat bronchial asthma, and theophylline toxicity continues to be an encountered clinical problem. With suicidal intention, a 61-year-old depressive male patient was sent to the hospital after ingestion of overdose theophylline. He had been followed up for bronchial asthma with about 10 microgram/ mL average plasma theophylline level. On arrival, he complained of dyspnea, palpitation and the plasma theophylline level was 252 microgram/mL. After 2 hours of ingestion, hypotension and tachycardia developed (Systolic blood pressure 50 mmHg, heart rate 190/ min). Other symptoms and signs were stuporous mental state and hypoxemia. Patient's peak plasma theophylline level reached 402 microgram/mL after 3 hours. beta-blocker, dopamine and midazolam were used for control of tachycardia, hypotension and prevention of seizure respectively. After Gastric lavage and administration of charchoal, he was treated with hemoperfusion for 3.5 hours, and serum level decreased. The patient was discharged in good health after 17 days.

OBJECTIVE: To compare the clinical outcomes of GnRH antagonist (cetrorelix(R)) with those of conventional GnRH agonist for down-regulation in assisted reproductive cycle. Materials and Method: Ninety-nine women undergoing IVF or ICSI were treated with either GnRH antagonist (cetrorelix(R)) or GnRH agonist (Lucrin(R)) for pituitary down regulation. The patient characteristics, basal hormone profile and IVF outcome were compared. RESULTS: There were no significant differences in age and duration of infertility between two groups. E2 (pg/mL)/LH (mIU/mL)/FSH (mIU/ mL) on the 3 day of menstrual period as a baseline were also not significantly different between two groups. The number of hMG amples administered (30.5+/-11.2 versus 47.6+/-16.4 ample/cycle) and the duration of stimulation (11.0+/-1.7 versus 14.1+/-2.2 days) were significantly lower in the cetrorelix(R) group. There were no significant differences in the fertilization and pregnancy rates, the number of embryo transferred, the number of mature oocyte and the number of embryo obtained between two groups. CONCLUSION: The cycles using an antagonist protocol shows a shorter duration of stimulation with comparable outcomes with few injections than those with an agonist protocol. GnRH antagonist can be effectively used as GnRH agonist for pituitary down regulation in IVF-ET cycles.
