BACKGROUND: Exercise has shown to slow down the progression from mild cognitive impairment (MCI) to dementia. In particular, not only resistance exercise has been verified to improve physical performance and muscle strength, leading to the prevention of fall-related injuries in the frail elderly, but also cognitive function. In this study, we investigated how high-speed elastic band training, applied using a high-speed power training protocol, affects cognition, physical performance and muscle strength of female elderly individuals with MCI. METHODS: Thirty-nine subjects diagnosed with MCI from one senior college using a Korean version of mini-mental state examination (MMSE-K) and a Korean version of the Montreal Cognitive Assessment (MoCA-K) were randomly divided into exercise group (n=20) and control group (n=19). The exercise group completed a 12-week high-speed resistance elastic band exercise program and was encouraged to exercise at home as well during the intervention period. RESULTS: The results showed significant increases in cognitive function, physical performance and muscle strength assessed by digit span forward test (P<0.001), digit span backward test (P=0.003), the Stroop test B (P=0.031), SPPB scores (P=0.010), right knee 60degrees extensor peak torque (P=0.004), 60degrees flexor peak torque (P=0.001), 180degrees extensor peak torque (P=0.020) and grip strength (P=0.025). CONCLUSIONS: Our study showed that participants with MCI who continued the high-speed elastic band training program for 12 weeks showed improvements in cognitive function, physical performance and muscle strength.

The study was conducted to analyze the impacts of COVID-19 on the number of dental trauma patients. Based on the data provided by the Health Insurance Review and Assessment Service’s Healthcare Bigdata Hub, dental trauma which occurred from 2010 to 2020 was analyzed.
Since the outbreak of COVID-19, the incidence of dental trauma per 100,000 decreased compared to the average Incidence between 2017 to 2019. By age, it decreased by 5.4% (p = 0.017) for 0 - 4 years old, 30.3% (p < 0.001) for 5 - 9 years old, 39.5% (p < 0.001) for 10 - 14 years old, 14.5% (p = 0.002) for 15 - 19 years old, 1.3% for 20 - 29 years old, 0.2% for 40 - 49 years old, 2.7% for 50 - 59 years old, 1.2% for 60 years old or older, but it increased by 2.5% for 30 - 39 years old. Compared monthly, before and after the outbreak of COVID-19 confirmed patients, the number of dental trauma patients dropped sharply.
After the outbreak of COVID-19, the incidence of dental trauma decreased significantly for under 20 years old, but the decrease was not significant for 20 years old or older.

PURPOSE: We examined the effect of stress on the pathophysiology of bladder stability in terms of enzyme levels, Rho-kinase, and bladder relaxation. MATERIALS AND METHODS: A total of 48 female Sprague-Dawley rats were studied in scheduled stress environments for 7, 14, and 28 days; 24 rats were in the control group and 24 rats were in the test (stressed) group. RESULTS: Estrogen decreased significantly whereas testosterone and dopamine increased significantly in the stress group (p<0.05). Rho-kinase was significantly increased in the rats exposed to stress stimuli for 14 days (p<0.05). Collagen types I and III in the bladder tissue were significantly higher in rats exposed to stress for 14 days and 28 days (collagen type I in the 14-day group, p<0.01; collagen type I in the 28-day group, p<0.05; collagen type III in the 14-day and 28-day groups, p<0.05). Voiding frequency increased significantly as the duration of stress exposure was prolonged, in addition to a significant decrease in volume per voiding (p<0.05). CONCLUSIONS: The changes observed in micturition pattern, factors that contribute to smooth muscle contraction, and relaxation in the female rat bladder support the hypothesis that stress affects bladder stability.

Carval syndrome is a severe heartworm infection where the worms have migrated to the right atrium and vena cava; this condition is associated with a myriad of clinical signs. Several non-surgical and interventional methods are currently used for mechanical worm removal. However, the success rate and complications related to these methods are heavily dependent on methodology and retrieval devices used. In this study, we developed a catheter-guided heartworm removal method using a retrieval basket that can easily access pulmonary arteries and increase the number of worms removed per procedure. With this technique, we successfully treated four dogs with caval syndrome.

PURPOSE: Vulvodynia is characterized by chronic vulvar pain caused by sexual intercourse and often results in female sexual dysfunction. Because the causes of vulvodynia are not clear, many patients do not receive optimal treatment. Recently, gabapentin and botulinum toxin A have both been shown to be effective treatments for vulvodynia. In this study, we retrospectively analyzed the clinical outcomes of botulinum toxin A and gabapentin treatment for chronic pain in women with this condition. MATERIALS AND METHODS: Seventy-three women with vulvar pain were administered either gabapentin (n=62) or botulinum toxin A (n=11) injections. Effectiveness was measured by use of a visual analogue scale (VAS). We analyzed the treatment method, treatment duration, success of treatment, and side effects or adverse reactions. RESULTS: Pain levels in both groups significantly decreased after treatment. In the gabapentin group, the VAS score decreased from 8.6 before treatment to 3.2 after treatment (p<0.001). The VAS score in the botulinum toxin A group was reduced from 8.1 to 2.5 (p<0.001). Side effects for both therapies were few and subsided with treatment with general antibiotics and nonsteroidal antiinflammatory drugs. CONCLUSIONS: Gabapentin and botulinum toxin A are safe and effective treatments for vulvodynia. This condition can cause sexual dysfunction and affect quality of life. However, with proper management, satisfactory outcomes for women with vulvodynia can be achieved.

BACKGROUND: Specimen requirements such as type of anticoagulant and number of tube for body fluid analysis vary with specimen type and requested laboratory tests. We compared the results of six clinical chemistry tests between EDTA anticoagulated and anticoagulant-free body fluids. METHODS: A total of 191 body fluids (45 pleural, 28 bronchoalveolar lavage, 35 peritoneal, 45 peritosol, and 38 synovial fluids) were aliquoted into EDTA tubes and anticoagulant-free tubes, and were simultaneously tested for total protein, albumin, glucose, lactate dehydrogenase, adenosine deaminase, and amylase. RESULTS: The coefficient of determination (R2) for all six clinical chemistry test results between EDTA anticoagulated and anticoagulant-free body fluids are more than 0.95 with the exception of glucose in bronchoalveolar lavage fluid (R2= 0.78). CONCLUSIONS: EDTA anticoagulated specimen could be used for testing routinely requested clinical chemistry tests in body fluid analysis, that only one tube of specimen is necessary to perform cell count, differential count, and clinical chemistry tests.

PURPOSE: We evaluated various preoperative anterior segment parameters measured with a Pentacam rotating Scheimpflug camera and compared them with those of conventional methods. We also evaluated the effect of different parameters on corneal endothelial cells after cataract surgery. METHODS: Pentacam examination was performed in 88 eyes from 88 patients to evaluate central anterior chamber depth (ACD(pentacam)), nuclear density (Densitometry(pentacam)), anterior chamber volume (ACV), and lens thickness (LT(pentacam)). We compared values of ACD(pentacam) with those of ultrasound (ACD(sono)) and also compared Densitometry(pentacam) values with those of Lens Opacities Classification System (LOCS III) classification. We evaluated the effect of the following preoperative values measured with Pentacam on postoperative endothelial cell loss: pupil size measured both preoperatively and before capsulorrhexsis (Pupil(CCC)), amount of viscoelastics, and LT measured by ultrasound (LT(sono)). RESULTS: A significant concordance was found between the two grading methods of nuclear opacity: Densitometry(pentacam) and LOCS III classification (tau(b) = 0.414, p = 0.000). We also found a positive correlation between ACD(pentacam) and ACD(sono) (r = 0.823, p = 0.000) and between ACD(pentacam) and ACV (r = 0.650, p = 0.000). There were significant differences between the results of LT(pentacam) and LT(sono). The final regression model identified Densitometry(pentacam), viscoelastics and Pupil(CCC) as independent predictors of decreased postoperative corneal endothelial cell density (CD) at postoperative day 3, and Densitometry(pentacam), viscoelastics, and ACV as independent predictors of decreased CD two months postoperatively (p<0.05). CONCLUSIONS: Good agreement was found between all results obtained with the Pentacam and conventional methods except LT. Analyzing anterior chamber parameters preoperatively using Pentacam could be helpful to predict postoperative endothelial cell loss.

A 2-year old castrated male Alaskan malamute was referred with primary complaints of marked anemia, hemeglobinuria and depression. Laboratory tests revealed canine babesiois with severe anemia. The dog was treated by blood transfusion and beneril (diminazene aceturate, 3.5 mg/kg IM). Two days after Beneril injection, the dog suddenly showed ataxia progressing to paresis. MRI revealed irregularly diffused lesions in the cerebellum. The case was tentatively diagnosed as cerebellar encephalopathy caused by diminazene toxicity. The dog successfully recovered following steroid therapy.

Vertebral artery injuries associated with C1 lateral mass screw insertion rarely occur during C1-2 fusion. The posterior inferior cerebellar artery (PICA) is uncommonly located at the C1 lateral mass insertion position. A 71-year-old woman with atlanto-axial subluxation and cord compression underwent C1-2 fusion. Sixth nerve palsy and diplopia were detected postoperatively, and decreased consciousness occurred on postoperative day 4. Brain magnetic resonance image (MRI) and computed tomography (CT) revealed PICA infarction. In the preoperative CT angiography, the PICA originated between the C1 and C2 level. In the postoperative CT scan, the PICA was not visible. The patient was treated conservatively for two weeks and recovered. PICA originating between the C1 and C2 level comprises 1.1–1.3% of cases. Therefore, vertebral artery anomalies should be evaluated prior to C1-2 fusion to prevent vessel injuries.
