Background: There are various conservative treatment options for lateral epicondylitis (LE). The aim is to evaluate pain, daily functioning, and complications after ultrasound-standardized autologous blood injections in patients with LE. Methods: For this prospective cohort study, consecutive patients (>18 years) diagnosed with LE were included. Autologous blood was injected using a medical device containing an injection disposable with 12 small needles (Instant Tennis Elbow Cure [ITEC]) device. Patient-Rated Tennis Elbow Evaluation (PRTEE), subjective elbow score (SES), palpation and provocation pain, satisfaction, and complications of treatment were measured at baseline and two months after treatment. Paired t-tests and Fisher's exact tests were used for calculating the difference between pre- and post-treatment outcomes. Results: Fifty-five elbows were analyzed. Mean time between pre- and post-treatment was 11.1 weeks (standard deviation [SD], 8.9 weeks). The mean PRTEE score decreased from 68.2 (SD, 15.7) before surgery to 53.2 (SD, 25.9; p<0.001) after. The mean SES improved from 36.9 (SD, 20.8) to 51.7 (SD, 27.4; p<0.001). Despite this improvement, only 44.7% of patients showed relevant clinical improvement in PRTEE, and 37.3% showed significant clinical improvement based on SES. Four patients reported a complication and the injection disposable failed three times. Conclusions: Ultrasound-standardized autologous blood injection using the ITEC device is not an effective tool in reducing symptoms related to LE. This study showed that only half of all patients experienced a positive effect. In this heterogeneous cohort of patients, we showed no added value of ultrasound standardization.

Objectives : The present study was conducted to evaluate the analgesic effects of automatically controlled heating acupuncture(ACHA) using 2 different pain models(acute pain and neuropathic pain) and 2 different stimulation conditions (heating $41.5^{\cdot}C$ and heating $44.5^{\cdot}C$) in Sprague-Dawley rats. Methods : Tail flick latency(TFL) to a noxious radiant heat stimulus in lightly anesthetized rats was measured before and after ACHA stimulation for 5-min at the Zusanli(ST36) acupoint. For the neuropathic surgery, the right superior caudal trunk was resected at the level between S1 and S2 spinal nerves innervating the tail. Two weeks after the nerve injury, ACHA stimulation($41.5^{\cdot}C$ or $44.5^{\cdot}C$) was delivered to Zusanli(ST36) for 5 min. The behavioral signs of warm allodynia were evaluated by the tail immersion test (i.e. immersing the tail in warm $water(40^{\cdot}C)$ and measuring the latency to an abrupt tail movement) before and after the ACHA stimulation. Results : In the TFL test, ACHA stimulations under both the conditions above produced more potent analgesic effects than plain acupuncture(PA, acupuncture needle insertion only) and control(no treatment). In the tail immersion test, ACHA stimulations under all of the conditions had markedly relieved the warm allodynia signs. Conclusion : Automatically controlled heating acupul1cture produced analgesic effecs in acute and neuropathic pains.

To study the recovery pattern of pulmonary function after decortication, the author performed serial pulmonary function tests using spirometry before and at lst., 3rd., 4th. week, lst., 3rd., 6th. month and 1st. year in 36 patients who underwent decortication from January 1989 to September 1991 at the Department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital, Pusan, Korea. Patients were divided into 3 groups by the degree of compression of lung parenchyme. Group I was classified below 20%, Group II between 21 to 40%, Group III above 41%. Their serial changes of pulmonary function test were compared. The obtained results were as follows; 1. Maximal voluntary ventilation was recovered in 1st post perative week and even greater improvement was noted in group III in which ratio to 44 % of the preoperative value. 2. Vital capacity reached nearly to preoperative values in 3rd postoperative week and had increased much further to 26 % above the preoperative figure in group II. 3. Forced expiratory volume in 1 second returned rather slowly in 3rd-4th postoperative week and the mean VC was improved more higher in group II than the other groups following decorti cation. 4. There was an greatest improvement over all tests[MW, VC, FEV1] in 2nd decade which ratios to preoperative value were 34, 25 and 22 % respectively.

When a patient is positioned at insulated bed and practitioner is positioned at insulated floor, that condition could be a cause of lessening effect in acupuncture practice. We investigated how Ground connection and Insulation could influence on the electrical meridian potential between practitioner and patient during acupuncture practice. We treated 30 normal healthy subjects with acupuncture and measured changes in the electrical potential between the stomach meridian points ST-39 and ST-37 in response to light touch after insertion of a needle at ST-36. At first, we stimulated non-insulated needle and measured electrical potentials for non ground, patient ground only, practitioner ground only, all ground respectively. Then we used insulated needles and measured same as above. Non-insulated all ground subject elicited positive mean potential $44.6{\pm}19.2{\mu}V$ and showed $181.4{\pm}59.7{\mu}V$ peak to peak potential. Practitioner ground only showed negative mean potential of $51.5{\pm}9.3{\mu}V$ and $367.4{\pm}27.8{\mu}V$ of peak to peak potential. Patient ground only revealed no mean potential of $2.9{\pm}1.3{\mu}V$, $16.4{\pm}11.9{\mu}V$ of peak to peak potential. All ground showed no mean potential of $1.6{\pm}0.7{\mu}V$, $3.3{\pm}1.9{\mu}V$ of peak to peak potential. In case of Insulated condition, there elicited no mean potential. Non ground and Practitioner only showed weak value of peak to peak potential as $7.8{\pm}2.6{\mu}V$ and $8.4{\pm}2.5{\mu}V$ each. But patient only and all ground showed no potential as $4.7{\pm}2.2{\mu}V$, $3.4{\pm}2.2{\mu}V$, respectively. Therefore, Ground connection modulate the energy transfer course between practitioner and patient. Insulation block energy transfer but static electrical impulse between practitioner and patient.

Objectives : The purpose of this study is to retrospectively analyze 3 years of inpatient ophthalmology consultation to Korean medicine ophthalmology, otolaryngology & dermatology department in Korean medicine hospital. Methods : We classified ophthalmological inpatient consultations between September 1st, 2019 and August 31st, 2022, based on electronic medical record by gender, age, hospitalized department, categories of diseases. Results : Total number of consultations were 111, and the average of age was 63.6. The proportion of female and male were 2.5:1. Among the 136 cases of eye disease referred, lacriminal production and discharge diseases accounted for the most at 54 cases(39.7%), of which 44 cases were dry eyes syndrome. Excluding dry eye syndrome, conjunctival disease occurred the most with 24 cases(17.6%). Consultations from department of Korean rehabilitation medicine, and Korean internal medicine were most common, because they have a comparatively large number of inpatients and long hospitalization period. Conclusions : This study identified the frequency of consultation and the disease group with many requests for each department. When inpatients complain of eye disease, consultation to Korean medicine ophthalmology, otolaryngology & dermatology department should be encouraged as accurate diagnosis and treatment using specialized equipment is possible and can be used for the purpose of progress observation and examination.
