Linguistic Validation of the Intermittent Self-catheterization Questionnaire for Patients With Neurogenic Bladder Who Perform Intermittent Catheterization for Voiding Dysfunction / 대한배뇨장애요실금학회지

PURPOSE: In recent years, the importance of patient satisfaction and quality of life—referred to as patient-related outcomes— has been emphasized, in addition to the evaluation of symptoms and severity through questionnaires. However, the questionnaires that can be applied to Korean patients with neurogenic bladder are limited. Therefore, the current study linguistically validated the Intermittent Self-Catheterization Questionnaire (ISC-Q) as an instrument to evaluate the quality of life of Korean patients with neurogenic bladder who regularly perform clean intermittent catheterization (CIC). METHODS: The validation process included permission for translation, forward translations, reconciliation, backward translation, cognitive debriefing, and proofreading. Two bilingual translators independently translated the original version of the ISC-Q into Korean and then combined the initial translations. A third bilingual translator performed a backward translation of the reconciled version into English. Five Korean-speaking patients with neurogenic bladder carried out the cognitive debriefing. RESULTS: During the forward translation process, the 24 questions of the ISC-Q were translated into 2 Korean versions. The terms used in each version were adjusted from the original version to use more conceptually equivalent expressions in Korean. During the backward translation process, several changes were involving substitutions of meaning. In the cognitive debriefing process, 5 patients were asked to complete the questionnaire. All patients agreed that the questionnaire explained their situation well. CONCLUSIONS: This study presents a successful linguistic validation of the Korean version of the ISC-Q, which could be a useful tool for evaluating treatment satisfaction in patients with neurogenic bladder performing CIC regularly.

Prognosis of the Pancreatic Carcinoma

PURPOSE: Currently, pancreatic exocrine carcinomas present with low resectability rates and poor survival, even after curative surgery. In this article, the clinicopathological characteristics, and treatment outcomes, of patients are analyzed and discussed. METHODS: Between 1983 and 2000, 106 exocrine pancreatic carcinoma patients were operated on at our institute. The medical records of 95 patients diagnosed with a ductal adenocarcinoma were reviewed, and the postoperative follow up results analyzed. RESULTS: The locations of the tumors were the head, body and diffusely spread in 76 (80.0%), 17 (17.9%) and 2 (2.1%) patients, respectively. Of the 95 patients, 29 underwent surgical resection (resectability rate; 30.6%), 33 palliative bypass procedures and the other 33 an exploration only. The 1-, 3-, and 5-year survival rates in the resection group were 66.7%, 19.8% and 9.9%, respectively. In the non- resection group the 1-year survival rate was 3.3%, with a mean survival period of 5.5 months. The overall 1-, 3- and 5-year survival rates were 23.0%, 6.6%, and 3.3%, respectively. From a multivariate analysis, the location of tumor (P= 0.0067), TNM stage (P=0.0010) and resectability of tumor (P<0.0001) were all significant prognostic factors. CONCLUSION: Pancreatic carcinomas have very low resectability, with a bad prognosis, and long term survival can only be obtained by their early detection and curative resection.

Dislocation of Left Arytenoid Cartilage after Endotracheal Intubation Using Light Wand: A case report / 대한마취과학회지

Complications from use of the light wand have been reported rarely. We present a case of arytenoid cartilage dislocation incurred by using this technique for intubation of a patient. A 35-year-old healthy woman was admitted for microsurgical cervical diskectomy. Anesthesia was induced and a 7.0 mm cuffed endotracheal tube with a light wand was inserted during blind orotracheal intubation. The trachea was extubated without any difficulty in the operating room after the surgery. In the third postoperative day, the patient complained sore throat and mild hoarseness. In the eighth postoperative day, the patient was discharged for follow-up of Department of neurosurgery. In the second day after the discharge, she was consulted to otolaryngology service in our hospital because she suffered from persistent hoarseness. Flexible nasopharyngolaryngoscopy revealed anterior and inferior dislocation of left arytenoid cartilage. The patient was taken to the operating room for reduction of the dislocated cartilage by the otolaryngologists. Despite the delayed reduction, which was performed tenth day after her initial injury, the patient,s hoarseness had resolved completely without further treatment.

Anatomical Measurement of The Upper Airway Dimensions with Computed Tomography / 대한마취과학회지

BACKGROUND: It is clinically important to know the distance of upper airway for airway management and respiratory care. The knowledge is useful for avoiding many possible complications due to endotracheal intubation by appropriate choice of endotracheal tube depth. METHODS: We investigated the distance from nose to carina according to the patient,s age, weight, height, sex with computed Tomography in 100 adults who had no anatomical abnormality of the upper airway, neck and head. RESULT: The length between upper incisor and vocal cord was 15.0+/-0.8 cm in male and 13.9+/-0.6 cm in female. The length between vocal cord and carina was 13.2+/-0.8 cm in male and 11.9+/-0.9 cm in female. The length between upper incisor and carina was 28.3 0.9 cm in male and 25.9+/-1.2 cm in female. The length between nose and vocal cord was 17.7+/-0.9 cm in male and 15.9+/-0.8 cm in female. The length between nose and carina was 30.9+/-1.2 cm in male and 27.9+/-1.3 cm in female. The distance of upper airway increased according to patient, s (n=100) height, weight and age(p0.05). CONCLUSION: The length between vocal cord and carina, nose and carina, incisor and carina increased according to patient, s (n=100) height, weight and age.

A Spinal Cord Tumor Found in the Patient with Herniated Nucleus Pulposus / 대한마취과학회지

A 35 years old female patient was admitted to our neuro-pain clinic with symptoms of low back pain(L4, L5 level) radiated to both lower(L3, L4, L5 level) extremities that developed 6 years prior to admission. Upon initial physical examination, motor weakness or sensory deficit was absent. But on straight leg raising test, it was restricted to 60 degree in both lower extremities. Low back pain and radiating pain improved significantly after we performed epidural steroid injection. However on the next day of procedure the patient complaints more pain and started to experience severe pain during overnight for 3 days. On computer tomography(CT, L3-S1 level), we find suspicious lesion of herniated nucleus pulposus at L5-S1. Otherwise were within normal limits. Based on these symptoms, to find the other lesions, subsequently magnetic resonance imaging(MRI) was performed. Spinal tumor was seen at L2-3 level(2 2 4 cm). Neurosurgical surgery was recommended, and operation was performed. The patient was diagnosed to ependymoma after excision and cytologic studies. Even if one lesion was diagnosed, it must be put off until any other diseases or underlying cancer are ruled out. We report a patient with spinal cord tumor missed on CT, but revealed on MRI in the evaluation and management of herniated nucleus pulposus related(L5-S1) low back pain.

Retrograde Nasogracheal Intubation with Laryngeal Mask Airway / 대한마취과학회지

Retrograde intubation has been often used in the patient who reveal difficulty intubation. But, it is time consuming procedure and the patient may be fall into hypoxemia. We have experienced a successful retrograde nasotracheal intubation without hypoxemia by using the Laryngeal Mask Airway. After induction of inhalation anesthesia, ordinary endotracheal intubation was failed in this 45-year-old male patient who was planned to clip the cerebral aneurysm, because the epiglottis could not be seen under direct laryngoscopy. We decided to perform retrograde nasotracheal intubation. Face mask was replaced with Laryngeal Mask Airway and ventilation was continued during procedure. A 18-gauge Tuohy needle was introduced through the cricothyroid membrane and then the epidural catheter was passed cephalad to larynx, distal hole of Laryngeal Mask Airway, and the end of Laryngeal Mask Airway. A 16-F Levin tube was introduced through right nasal cavity and Laryngeal Mask Airway was removed, the Levin tube was tied with epidural catheter in the oral cavity. The epidural catheter was placed from cricothyroid membrane to right nares. The endotracheal intubation was performed successfully by sliding over the catheter. In the postoperative evaluation, significant complications were not detected. The procedure was performed in about 2 minutes and the apneic time was less than 30 seconds. We believe that this procedure may be useful in the patients who may suffer from hypoxemia.

Measurement of Trachea with MRI in the Normal Korean Adults / 대한마취과학회지

It is clinically important to know the size of normal trachea for airway management and respiratory care. The knowledge is useful for avoiding many possible complications due to tracheal intubation by appropriate choice of endotracheal tube size. Therefore, we investigated antero-posterior(A-P) diameter, transverse diameter and cross- sectional area(CSA) of trachea at various level with MRI(magnetic resonance imaging) in 70 males and 79 females who were divided into three age groups(group 1: 16-39 year of age, group 2: 40-59 year of age, group 3: 60-83 year of age), and they had no abnormalities in cardiopulmonary system. The results were as follows; 1. A-P 2. Transverse 3. Narrowing portion 4. CSA 1. A-P diameter of trachea was 17.1+/-1.4 mm in male and 13.9+/-1.3 mm in female. Transverse diameter of trachea was 15.1+/-1.6 mm in male and 13.3+/-1.5 mm in female(Table 1). A-P and Transverse diameters were greater in male than in female (P<0.05). 2. C-7 was the narrowest portion of A-P diameter in both sex (P<0,05). C-5 was the narro- west portion of transverse diameter in both sex (P<0.05). 3. A-P diameters of trachea among male patients were 17.1+/-1.2 mm, 17.41.6 mm, and 16.6+/- 1.3 mm in group 1, 2 and 3 (Table 3, Fig. 4). A-P diameters of trachea in female age group 1, group 2 and group 3 were 13.7+/-1.2 mm, 14.3+/-1.3 mm, and 13.6+/-1.5 mm(Table 3, Fig. 4). Transverse diameters of trachea in male age group 1, group 2 and group 3 were 14.8+/-1.4 mm, 15.1+/-1.7 mm, and 15.4+/-1.6 mm(Table 3, Fig. 4). Transverse diameters of trachea in female age group 1, group 2 and group 3 were 13.0+/- 1.2 mm, 13.6+/-1.9 mm and 13.5+/-1.4 mm(Table 3, Fig. 4). 4. CSA(cross sectional area) of trachea were 201.1+/-31.3 mm(2) in male and 145.4+/-27.7(2) mm in female(Table 4). 5. CSA at C5, C6, C7 and Tl in male were 175.9+/-61.1 mm(2), 201.1+/-43.8 mm(2), 196.2+/-36.2 mm(2) and 230.9+/-463 mm(2) (Table 4, Fig. 5). CSA at C5, C6, C7 and Tl in female were 127.0+/- 33.4 mm(2), 138.434.6 mm(2), 140.734.7 mm(2) and 171.7+/-42.0 mm(2) (Table 4, Fig. 5). 6. CSA of trachea among male patients were 198.1+/-28,5 mm(2), 206.2+/-33.0 mm(2) and 198.3+/-33.1 mm(2) in group 1, 2 and 3 (Table 5, Fig. 6). CSA of trachea in female age group 1, group 2 and group. 3 were 140.2+/-25.0 mm(2), 152.8+/-32.4 mm(2) and 145.6+/-25.1 mm(2) (Table 5, Fig. 6). But there was no significant difference between groups according to the sex. 7. CSA of trachea in age groups were stastically insignificant for both sex.
