The gate control theory was proposed by Melzack & Wall in 1965. This theory implies that selective stimulation of cutaneous afferent fibers of large diameter inhibits pain. Transcutaneous electrical stimulation(TNS) is a practical employment of this concept. TNS was used on 14 herpes zoster patients to relieve associated pain. Good effeet was obtained in 13 patients. They experienced relief of their pain for 1-4 hours after 20 minutes of application. TNS has many advantages over analgesic drugs in the control of pain in herpes zoster.

Objectives:
Cheyne-Stokes respiration (CSR) is frequently found in critically ill patients and is associated with poor prognosis. However, CSR has not been evaluated in neurocritical patients. This study investigated the frequency and prognostic impact of CSR in neurocritical patients using biosignal big data obtained from intensive care units.
Methods:
This study included all patients who received neurocritical care at the tertiary hospital from January 2018 to December 2019. Clinical information and biosignal data of intensive care units were used and analyzed. The respiratory curve was visually assessed to determine whether CSR and obstructive sleep apnea (OSA) were present, and a heart rate variability (HRV) was obtained from the electrocardiogram.
Results:
CSR was confirmed in 166 of 406 patients (40.9%). Patients with CSR were older, had a higher frequency of cardiovascular risk factors as well as heart failure, and had a poor outcome (modified Rankin scale ≥4). As a result of multiple regression analysis adjusted for other variables, CSR was significantly associated with poor outcome with an odds ratio of 2.27 times higher (95% confidence interval 1.25–4.14, p=0.007). HRV analysis demonstrated that CSR and OSA had distinct autonomic characteristics.
Conclusions
This study first revealed the substantial frequency of CSR in neurocritical patients and suggests that it can be used as a predictor of poor prognosis in neurocritical care.

BACKGROUND: The gaitaids are helpful for the patients of gait disturbance, but there was no study about the quantitative assessment of the effectiveness of gaitaids of several different types. But proper use of gaitaids is important for the disabled who is suffered from falls with or without trauma. The appropriate prescription of gaitaids is coming from the objective assessment for gaitaids. METHODS: We evaluated the 'balance index(BI)', which is originally suggested assessment scale by author, for the five different gaitaids :mono-cane, quad-cane, forearm crutch, axillary crutch, walker We assessed the difference of B.1 with or without using each gaitaids examined by 50 healthy adults and 20 stroke patients. RESULTS: The BI in the normal adult was 34.5+/-2.7, and 21.0+/-6.9 in the stroke patients. The balance index o( walker user was 37.6+/-1.4, which was the highest score. The BI of quad-cane was 30.1 +/-4.8, which was the next highest score and the BI of mono-cane, forearm crutch, axillary crutch were 25.5+/-5.6, 25.5+/-5.7, 25.5+/-5.4, which were lower than that of quad-cane. CONCLUSION: It can be suggested that the walker is the most effective for the support balance on gait and the quad-cane is more effective than mono-cane or crutches for balance support.

Behcet's disease is characterized by recurrent orogenital ulcers and ocular and cutaneous inflammatory lesions. Cardiovascular involvement, which may be artrial or venous, is rare but carries a particularly poor prognosis. One of the known vascular complications of Behcet's disease is aneurysm formation or venous thrombosis. We recently experienced a Behect's disease with multiple arterial aneurysms and thrombosis and report this case with review of literatures.

Development of acetabulum and epiphysis of the femoral head following reduction in seventy-four patients with ninty-one congenitally dislocated hips were assessed radiologically. Acetabular index, CE angle of Wiberg, neck-shaft angle of the femur and overgrowth of the pelvis and femur were measured according to the various treatment. To evaluate results, the method of treatment was divided into four groups; closed reduction, open reduction, open reduction combined with pelvic osteotomy and modified Klisic operation (open reduction, pelvic osteotomy, femoral osteotomy and so on). Each treatment was compared with three subgroups according to ages; first subgroup was belong to patients under one year of age, second from one year to three years, third over three years. This paper agrees to Harris (1976) and Lindstrom (1979) about improvement of acetabular index and CE angle of Wiberg that showed a rapid rate of repair in the first 6 months and thereafter slowly progressed to normal range of degree. Overgrowth of pelvis and femur was also noticed in cases of hips treated pelvic and/or femoral osteotomy, moreover even in cases of open reduction only. The goal of this preliminary investigation may be supposed to propose the idea which method of treatment to the first visiting patient will approach the most satisfactory final result.

Purpose:
To evaluate the effects and limitations of lacrimal endoscopy without silicone tube intubation in patients with epiphora.
Methods:
We conducted a retrospective chart review of 64 eyes in 49 patients who underwent lacrimal endoscopy between May 2021 and May 2022. The clinical characteristics, irrigation test results, lacrimal endoscopic findings, and type of surgery were analyzed.
Results:
The mean duration of symptoms was 31.2 months, and was significantly longer in the failure group than in the success group (p = 0.043). Irrigation tests showed passage, partial obstruction, and complete obstruction in 20 (31.3%), 16 (25.0%), and 28 (43.7%) eyes, respectively. Lacrimal endoscopy showed narrowing, mucus, fibrosis, granulation, and stones in 41 (64.0%), 12 (18.8%), 6 (9.3%), 3 (4.7%), and 2 (3.1%) eyes, respectively. Following lacrimal endoscopy, 32 (50.0%) eyes each were included in the success and failure groups. Preoperative irrigation test results did not affect the success rate (p = 0.203). Silicone tube intubation and dacryocystorhinostomy were performed in 5 (7.8%) and 8 (12.5%) eyes, respectively, because the symptoms did not improve after lacrimal endoscopy.
Conclusions
Lacrimal endoscopy, performed without silicone tube intubation, was effective in improving symptoms and may guide the choice of surgical technique, if required.

OBJECTIVES: The objective of this study was to evaluate the performance of risk-adjusted mortality models for colorectal cancer surgery. METHODS: We investigated patients (n=652) who had undergone colorectal cancer surgery (colectomy, colectomy of the rectum and sigmoid colon, total colectomy, total proctectomy) at five teaching hospitals during 2008. Mortality was defined as 30-day or in-hospital surgical mortality. Risk-adjusted mortality models were constructed using claims data (basic model) with the addition of TNM staging (TNM model), physiological data (physiological model), surgical data (surgical model), or all clinical data (composite model). Multiple logistic regression analysis was performed to develop the risk-adjustment models. To compare the performance of the models, both c-statistics using Hanley-McNeil pair-wise testing and the ratio of the observed to the expected mortality within quartiles of mortality risk were evaluated to assess the abilities of discrimination and calibration. RESULTS: The physiological model (c=0.92), surgical model (c=0.92), and composite model (c=0.93) displayed a similar improvement in discrimination, whereas the TNM model (c=0.87) displayed little improvement over the basic model (c=0.86). The discriminatory power of the models did not differ by the Hanley-McNeil test (p>0.05). Within each quartile of mortality, the composite and surgical models displayed an expected mortality ratio close to 1. CONCLUSIONS: The addition of clinical data to claims data efficiently enhances the performance of the risk-adjusted postoperative mortality models in colorectal cancer surgery. We recommended that the performance of models should be evaluated through both discrimination and calibration.

Dissociated vrtical deviation(DVD) is frequently associated with infantile esotropia. It is hard to find DVD before surgery for esodeviation, and usually found after surgery. We studied the occurrence of DVD in 176 patients who had had horizontal rectus muscle surgery for the correction of infantile esotropia and followed up for 6 months or more. DVD was seen in 78 patients(44.3%), preoperatively in 27 patients(34.6%) and postoperatively in 51 patients(65.4%). Among 51 patients with DVD after surgery, DVD occurred in 24.0% of patients with preoperative angle of esodeviation less than 50 PD and in 44.6% of patients with preoperative angle of esodeviation more than 51 PD(P<0.01). Most of them(25 of 51 patients) developed DVD within 6 months after esodeviation surgery, however, 12 patients were noted to develop even after 2 years. This shows that we need long term follow-up for the detection of DVD. The occurrence of DVD was not influenced by the time of surgery for esodeviation(P>0.05). Inferior oblique overaction(IOOA) was accompanied with DVD in 71.8% and occurred without DVD in 28.6%. This study revealed postoperative DVD developed more in large angle esotropia such as deviation angle greater than 51 PD, and IOOA was frequently accompanied. The result suggests that in large angle infantile esotropia with mild IOOA and DVD or fundus extorsion we may need the preventive correction of DVD and IOOA.
