1.Effects of Knowledge of Result Versus Knowledge of Performance on Treadmill Training on gait ability in Stroke Patients: A Randomized Clinical Trial
Journal of Korean Physical Therapy 2020;32(2):107-113
Purpose:
This study compared the walking ability of chronic stroke patients following either treadmill training with knowledge of the result (KR group) or treadmill training with knowledge of the performance (KP group).
Methods:
Nineteen patients with chronic stroke were recruited from a rehabilitation hospital. The patients were divided into two groups: a KR group (10 patients) and a KP group (9 patients). They received 30 minutes of neuro-developmental therapy and treadmill training 30 minutes, five times a week for three weeks. The gait parameters were measured before and after training using the Optogait system.
Results:
After the training periods, the KR group showed significant improvement in gait speed, cadence, step length of the unaffected limb, stance time of the affected limb, and functional gait assessment compared to the KP group (p<0.05).
Conclusion
The results showed that treadmill training with KR was more effective in improving the gait speed and cadence, step length of the unaffected limb, stance time of the affected limb, and functional gait ability than the treadmill training with KP. Therefore, to improve the walking ability of stroke patients, it is necessary to consider treadmill training with KR. If it can be combined with conventional neurological physiotherapy, it would be an effective rehabilitation for stroke patients.

Met protein is a transmembrane 190 kD heterodimer with tyrosine kinase activity, encoded by c-Met oncogene. It serves as a high affinity receptor for hepatocyte growth factor (HGF)/scatter factor (SF), a cytokine which stimulates cell proliferation, motility, and invasion. In this study, we immunohistochemically evaluated the expression of Met/hepatocyte growth factor receptor in colorectal cancers. Met protein was expressed in 31 of 72 patients (43.1%). The staining pattern was cytoplasmic in nature, present throughout the tumor, and showed variable intensity from case to case. The relationship between the expression rate and intensity, and age and sex of patients, tumor size (p=0.645), tumor site (p=0.902) and tumor differentiation (p=0.844) was not statistically significant. The expression rate and intensity were significantly correlated with lymphovascular invasion (p=0.001), lymph node metastasis (p=0.010), depth of invasion (0.019), and stage (p=0.023). Cytoplasmic accumulation of Met protein was not associated with enhanced PCNA index of tumor cells (p=0.052). These results suggest that Met protein may play an important role in the invasion and metastasis of colorectal cancer cells.

Epithelial cadherin (E-cadherin) is a Ca2+ -dependent cell-cell adhesion molecule that connects cells via homotypic interactions. Its function is critical in the induction and maintenance of cell polarity and differentiation, and its loss is associated with an invasive and poorly differentiated phenotype in a wide range of tumors. Formalin-fixed, paraffin-embedded tissue sections from 36 cases of cervical intraepithelial neoplasia (CIN) and 14 cervical squamous cell carcinomas were investigated for the expression of E-cadherin immunohistochemically. While E-cadherin expression was usually restricted on the cell membrane of basal and parabasal cells in normal cervix, the presence of cytoplasmic E-cadherin was found to be associated with its grade in CIN lesions. Also, marked cytoplasmic staining was commonly revealed in poorly differentiated ones than well-differentiated squamous cell carcinomas. More intense reactivity of cytoplasmic E-cadherin was frequently seen in the foci of invasion than adjacent carcinoma in situ, and in its periphery than the center of tumor islands. In addition, DNA ploidy and S-phase fraction of squamous cell carcinomas were analyzed and compared with those of CIN lesion. We found that invasive squamous cell carcinomas more frequently disclosed DNA aneuploidy than CIN lesions, and there was correlation between cytoplasmic E-cadherin expression and DNA aneuploidy. Also, cytoplasmic E-cadherin-reactive cervical neoplasms had a higher rate of cell proliferation than that of membranous E-cadherin-reactive cases. These data suggest that the increased cytoplasmic E-cadherin expression may represent one of the abnormalities underlying the loss of polarity and invasiveness of cancer cells, and the abnormal E-cadherin expression combined with/without DNA ploidy or S-phase fraction may serve as a prognostic indicator.

The purpose of this study was to investigate nutrition knowledge, dietary attitude and a food habits of middle school students. The study was carried out through questionnaire. The subjects were 431 middle school students (boys 298, girls 133) in Chonbuk area. In nutrition knowledge, there were no significant differences in total scores between boys and girls. However, the girls showed higher score in knowledge of weight control than boys did (p < 0.05). In dietary attitude, there were significant differences in attitude of "balanced meal (p < 0.05)", "sufficient protein intake (p < 0.01)", "food diversity (p < 0.001)" and "overeating (p < 0.01)" between boys and girls. The boys showed better dietary attitudes than the girls did. In food habits, there were significant differences in the rate of skipping breakfast (p < 0.05), the rates of skipping dinner (p < 0.01), the frequency of snacks (p < 0.05), the type of snacks (p < 0.05) between boys and girls. The girls showed higher rates of skipping a meal and frequency of snacks than the boys did. It suggests that gender should be considered for an effective and practical nutrition education for middle school students to improve dietary attitudes and food habits.

The authors performed percutaneous antegrade pyelography guided by ultrasound on 33 patients, from J une 1982 to October 1984, at the department of radiology, Busan National University Hospital. The results obtained were as follows: 1. Of the 31 cases,17 cases (5 1.5%) were female and 16 cases (48.5 %)were male,and age distribution was nearly even, but most prevalent age group was third decade. 2. Comparing intravenous pyelographic findings with ultrasonographic findings, pyelographically non. visualized kidney 15 cases (45 .5%) were hydronephrosis 12 cases, multiple cysts 2 cases, and intrarenal cystic mass 1 case, ultrasonographically. Pyelographically hydronephrosis 9 cases (27.3%) were all hydronephrosis, ultrasonographically. Intrarenal mass 5 cases (15.2%) were all intrarenal cystic mass, NVK with air in kidney 1 case (3.0%) was air in perirenal space, partial NVK 1 case (3.0%) was per. irenal fluid , suprarenal mass 1 case (3 .0%) was suprarenal intrarenal and huge perirenal cystic masses, ultraso nograp h ically. 3. On technical reliability of antegrade pyelography under ultrasound gUide, 31 cases (93 .9%) could be done fluid aspiration and visualization, and 2 cases (6.1 %) could be only done fluid aspiration but failed visualization . 31 successful cases were visualization of collecting systems 23 cases, visualization of cyst 6 cases, i!nd visualization of perirenal space 2 cases. 2 partial successful cases were perirenal injection 1 case and parenchymal injection 1 case. 4. On fluid aspiration, 22 cases (66.7%) were clear, but 11 cases (33.3%) were not clear, which were pus 7 cases, turbid urine 2 cases, bloody urine 1 case, and bloody pus and air 1 case. 5. Comparing ultrasonographic findings with antegrade pyelographic findings, ultrasonographically hydronephrosis 21 cases revealed obstruction in 16 cases, antegrade pyelographically, which were consisted of ureteral stricture 14 cases, ureteral stone 1 case, and ureteral mass 1 case, non-obstruction in 4 cases, which were consisted of pyonephrosis 2 cases, posterior urethral valve 1 case, and megaureter 1 case, and other 1 case was visualization failure. Ultrasonographically intrarenal cystic mass 6 cases were simple renal cyst 4 cases, and infected renal cyst 2 cases, antegrade pyelographically. Multiple cysts 2 cases were lobulated huge renal cyst 1 case, and visualization failure 1 case, which was multi.cystic kidney. Air in perirenal space 1 case was emphysematous pyelone. phritis, suprarenal cystic mass 1 case was complete duplication with ectopic ureteral orifice, perirenal fluid 1 case due to kidney fracture was perirenal fluid , and intrarenal and perirenal cystic mass was per irenal abscess, antegrade pyelographically. 6. On ana lysis of anteg rade pyelography result as next diagnostic step of ultrasound, 31 successful cases were 27 conclusive diagnostic cases (87.1%), and 4 heplful diagnostic cases (12.9%) with percutaneous antegrade pyelography guided by ultrasound . 7. Antegrade pyelography provides significant diagnostic information on the nature of the obstructive lesion and can be performed as an adjunct to retrograde study or as an alterative to a pyelogram. 8. Ultrasonographic examination could be performed easiJy in diagnosis of renal and perirenal diseases as non.invasive method without risk of radiation hazard , and was not influenced by renal function. 9. Ultrasound is considered a most advantageous aid to the performance of antegrade pyelography and has yie lded valuab le diagnostic information in patients with obstructive hydronephrosis.

7.The Effects of Clam Exercise on the Trunk Control and Balance of Stroke Patients
Journal of Korean Physical Therapy 2020;32(6):372-377
Purpose:
The purpose of this study was to verify the effect of applying clam exercise on improving trunk control and balance ability in stroke patients. Based on this, we tried to provide clinical information.
Methods:
In this study, 18 patients with chronic stroke were recruited from a rehabilitation hospital. The patients were divided into two groups: a clam exercise group (9 patients) and a control group (9 patients). After 30 minutes of neuro-development therapy, they performed clam exercise or bridge exercise for 3 weeks, 5 times a week for 30 minutes. A trunk impairment scale (TIS) and a postural assessment scale for stroke patients-trunk control (PASS-TC) were performed to evaluate the subjects’ ability to control trunk before and after intervention. Balance ability was measured by Balancia before and after intervention.
Results:
After the training periods, area 95% COP and weight distribution of the affected side were significantly different from the clam exercise group compared to the control group (p<0.05).
Conclusion
Based on the results of this study, in can be seen that the clam exercise is effective in improving the balance ability compared to the bridge exercise. Maintaining the standing posture requires muscle strength of the hip abduction and extension, which is the result of the clam exercise selectively strengthening these muscles. Therefore, if you want to provide intervention to improve the balance of stroke patients, it is recommended to perform a clam exercise.Keywords : Balance, Clam exercise, Stroke, Trunk control
8.Effect of Cryotherapy on Muscle Strength and Balance on the Ankle Joint in Patients with Stroke
Journal of Korean Physical Therapy 2021;33(2):91-96
Purpose:
This study investigated the effects of cryotherapy on the ankle joint muscle strength and balance ability in stroke patients with ankle joint muscles.
Methods:
In this study, 20 patients with chronic stroke were recruited from a rehabilitation hospital. The patients were divided into two groups: a cryotherapy group (10 patients) and a control group (10 patients). The cryotherapy group performed sit-to-stand training for 15 minutes and then cryotherapy for the minutes. In the control group, after sit-to-stand training for 15 minutes, blocked cryotherapy was provided for three minutes. In both groups, the interventions were provided five times a week for three weeks. The strength of the ankle joint muscles was measured before and after the training using the Biodex systems 3. The static balance ability was measured using balancia software, and the dynamic balance ability was measured by performing the sit-to-stand test (FTSST) five times.
Results:
After the training periods, the cryotherapy group showed significant improvement in the ankle dorsiflexor strength, ankle plantarflexor strength, weight distribution of the affected side, and FTSST compared to the control group (p<0.05).
Conclusion
Based on these results, cryotherapy could be considered an effective method to improve the strength of ankle joint muscles. Cryotherapy improves muscle strength as it increases the motor neuron excitability. Therefore, cryotherapy may be considered to improve the strength of the ankle joint muscles of stroke patients.
9.Effects of Repetitive Sit to Stand Training on the Knee Extensor Strength and Walking Ability in Subject with Total Knee Replacement Patients
Journal of Korean Physical Therapy 2021;33(1):34-39
Purpose:
The purpose of this study was to verify the effectiveness of repetitive sit to stand training to improve knee extensor strength and walking ability of total knee replacement patients.
Methods:
In this study, 12 patients with total knee replacement patients were recruited from a rehabilitation hospital. They were divided into two groups: a repetitive sit to stand group (n=6) and a control group (n=6). They all received 30 minutes of continuous passive motion (CPM). After that, the repetitive sit to stand group performed repetitive sit to stand training, and the control group performed resistance exercise for 15 minutes five times a week for 2 weeks. After 2 weeks of training, knee extensor strength and spatiotemporal gait parameters were measured. Knee extensor strength was measured by Biodex system 3, walking ability was measured by Biodex gait trainer 2. Paired t test was performed to verify the difference between before and after intervention within the group, and analysis of covariance was used to verify the differences between the two groups.
Results:
After the training periods, the repetitive sit to stand group showed a significant improvement in knee extensor muscle strength, walking speed, step length of the operated side, and step length of the non-operated side (p<0.05).
Conclusion
The results of this study showed that repetitive sit to stand training was more effective in improving knee extensor muscle strength and walking ability. Therefore, to strengthen knee extensor muscles and improve the walking ability of total knee replacement patients, it is necessary to consider repetitive sit to stand training.

Allergy, Asthma & Respiratory Disease 2020;8(4):213-219
Purpose:
Respiratory syncytial virus (RSV) is one of the most common causes of respiratory tract infections, especially in patients aged < 3 years. There are 2 antigenically different RSV subtypes, A and B. This study aimed to assess if the RSV subtype is independently associated with increased disease severity.
Methods:
We retrospectively collected data from the medical records of children hospitalized with RSV infection, aged < 3 years at Dong-A University Hospital between September, 2014 and December, 2018.
Results:
RSV A and RSV B infections were observed in 111 and 66 cases, respectively. Pneumonia was most commonly observed, followed by bronchiolitis in both subtypes. There were no significant differences between the groups regarding birth weight, gestational age, and incidence of having siblings. The duration of admission, duration of fever, and severity index were similar between the groups. The incidence of high fever (> 39°C) was slightly higher in the RSV B group (13.6%) than in the RSV A group (11.7%), although the difference was not statistically significant. Laboratory findings, including the neutrophil-lymphocyte ratio, were similar between the groups. The incidence of systemic steroid therapy was higher in the RSV A group (12.6%) than in the RSV B (3.0%) group (P= 0.03). Patients aged < 12 months, the incidences of oxygen therapy (P= 0.03) and systemic steroid therapy (P= 0.04) were higher in the RSV A group, suggesting that patients aged < 12 months with RSV A infection may have clinically more severe disease.
Conclusion
We recommend intensive monitoring if RSV A infection is detected in young children under 12 months.
