Voiding cystourethrography (VCUG) is a commonly performed diagnostic procedure for the evaluation of vesicoureteral reflux with urinary tract infection or congenital renal diseases in children. The procedure is relatively simple and cost-effective, and complications are very rare. The iatrogenic complication of VCUG range from discomfort, urinary tract infection to bacteremia, as well as bladder rupture. Bladder rupture is a rare complication of VCUG, and only a few cases were reported. Bladder rupture among healthy children during VCUG is an especially uncommon event. Bladder rupture associated with VCUG is usually more common in chronically unused bladders like chronic renal failure. Presented is a case of bladder rupture that occurred during a VCUG in a healthy 9-month-old infant, due to instilled action of dye by high pressure. This injury completely healed after 7 days of operation, and it was confirmed with a postoperative cystography. The patient's bladder volume, underlying disease, velocity of the contrast media instilled, catheter size, and styles of instillation are important factors to prevent bladder rupture during VCUG. Management of bladder rupture should be individualized, but the majority of infants are treated with the operation. In conclusion, bladder rupture is a rare complication, however, delicate attention is needed in order to prevent more dire situations.

Objectives: The maxillary sinus mucosa is reported to recover to preoperative sterility after sinus floor elevation. However, when drainage of maxillary sinus is impaired, recovery can be delayed and maxillary sinusitis can occur. Therefore, in this study, we investigated the correlations between anatomic variants that can interrupt the ostium of the maxillary sinus and incidence of complication after sinus lifting. Materials and Methods: The subjects are 81 patients who underwent sinus lifting in Wonkwang University Dental Hospital (Iksan, Korea). Computed tomography (CT) images of the subjects were reviewed for presence of nasal septum deviation, anatomic variants of the middle turbinate, and Haller cells. Correlations between anatomic variations and occurrence of maxillary sinusitis were statistically analyzed. Results: Patients with anatomic variants of ostio-meatal units, such as deviated nasal septum, concha bullosa or paradoxical curvature of the middle turbinate, or Haller cells, showed a higher rate of complication. However, only presence of Haller cell showed statistically significant. Conclusion: Before sinus lifting, CT images are recommended to detect anatomic variants of the ostio-meatal complex. If disadvantageous anatomic variants are detected, the use of nasal decongestants should be considered to reduce the risk of postoperative sinusitis.

Ophthalmic complications after tooth extraction are rare but discomforting events. This paper reports the rare complications of a 20-year-old male patient who presented with transient blurring of vision after surgical extraction of several teeth under general anesthesia. Additional diagnostic tests were performed to discern the reason for the pseudomyopia. A literature review was carried out by searching for articles published from 1936 to 2019 using the keywords "dental," "ophthalmic," "complication," "blurring of vision," and "accommodation disturbance" in PubMed. Only six patients with detailed ophthalmic symptoms similar to those of our patient have been reported. If blurred vision or a myopic shift in refraction is present, pseudomyopia should be suspected, and cycloplegic refraction is essential for diagnosis. The condition improves spontaneously

Purpose : The aim of this study was to compare surgical complications between simple implant placement and implant placement combined with complicated surgical procedures. We also evaluated prosthetic complications according to the specific types of prosthesis. Material and Method : A retrospective analysis of dental chart of patients who was performed implant therapy during the period from June 2003 to December 2005 was carried out. This study was performed on 408 patients (208 male, 200 female). In addition, 1671 implants were performed. Based on their medical record and radiographs, the authors evaluated surgical and prosthetic complications, surgical procedures accompanied at the time of implant, risk factors of implant failure etc. Result : Surgical complications were developed on 358 implants(21.4% on total placed implants) and wound dehiscence was most prevalent complication. On maxillary posterior area, surgical complications developed more frequently on implants with major surgery and showed a significant difference. And complication rate of implants accompanied with GBR was higher than that of simple implants placement and also showed significant difference. The implant supported prosthesis showed no statistical difference in the occurrence of complications according to the types of prosthesis, and food retention was the most common post-prosthetic complication. Also we speculated that length and width of implant showed significant correlation to the failure of implant primary osseointegration. Conclusion : Based on the result, clinician should provide more careful maintenance for patients with implant placement accompanied by complicated surgical procedure. And periodic maintenance for the patient is requested for long-term survival of implant therapy.

Introduction : The objective of this study was to analyze the complication rates after completion thyroidectomy and compare them with primary total benign and malign thyroidectomy causes in total of 647 patients. Patients and Methods: Among 647 patients, there were 159 receiving completion thyroidectomy for differentiated thyroiud cancer (DTC) (Group 1); 217 patients receiving total thyroidectomy for DTC (Group 2) and 271 given total thyroidectomy for benign diseases (Group 3). Results: When groups were compared for complications, there were no significant difference except temporary hypocalcemia between completion thyroidectomy and total thyroidectomy for DTC. When the total thyroidectomies were compared (Group 2 and 3), there were no significant difference observed except unilateral temporary RLN palsy. Conclusion: With improvements in surgical technique and experience, complication rates of thyroidectomy performed for benign or malign diseases are reduced. In spite of the improvement in surgical experience, temporary RLN palsy and hypoparathyroidism are the main complications in completion thyroidectomies which need special attention. To evaluate the patients more carefully in preoperative period and performing adequate thyroidectomy appears more logical.

Objective : The purpose of this study was to analyze the variability of clopidogrel responses according to duration of a clopidogrel drug regimen after stent-assisted coil embolization (SAC), and to determine the correlation between the variability of clopidogrel responses and thromboembolic or hemorrhagic complications. Methods : A total of 47 patients who underwent SAC procedures to treat unruptured intracranial aneurysms were enrolled in the study. Preoperatively, patients received more than seven days of aspirin (100 mg) and clopidogrel (75 mg), daily. P2Y12 reaction unit (PRU) was checked with the VerifyNow test one day before the procedure (pre-PRU) and one month after the procedure (post-PRU). PRU variability was calculated as the difference between the initial response and the follow-up response. Patients were sorted into two groups based on their response to treatment : responsive and hypo-responsive. Results : PRU variability was significantly greater in the hypo-responsive group when compared to the responsive group (p=0.019). Pre-PRU and serum platelets counts were significantly correlated with PRU variation (p=0.005 and p=0.004, respectively). Although thromboembolic complication had no significant correlated factors, hemorrhagic complication was correlated with pre-PRU (p=0.033). Conclusion : In conclusion, variability of clopidogrel responses during clopidogrel medication was correlated to serum platelet counts and the initial clopidogrel response. Thromboembolic and hemorrhagic complications did not show correlation with the variability of clopidogrel response, or the clopidogrel response after one month of medication; however, hemorrhagic complication was associated with initial clopidogrel response. Therefore, it is recommended to test patients for an initial clopidogrel response only, as further tests would be insignificant.

Cervical epidural steroid injection is indicated for radicular symptoms with or without axial neck pain. Complications are rare but can be serious. Here, we report the case of a 54-year-old man with cervical radicular pain who was treated with cervical epidural steroid injection. Injection was administered twice under fluoroscopic guidance with the loss-of-resistance technique using air to confirm the epidural space. After the second procedure, the patient complained of severe persistent headache and was diagnosed with pneumocephalus on brain computed tomography. The patient returned home without any neurological complication, after a few days of conservative treatment. Though, a fluoroscopic guidance cervical epidural injection is also known to diminish the risk of complications. Physicians should always keep in mind that it does not guarantee safety, particularly in the cervical region, related to its anatomical considerations.

Purpose : Cerebrovascular disease is the most frequent cause of death in Korea and it remains severe disabilities disturbing normal life, According to the previous studies, mortality of the stroke in the first one week is up to the 20% and 95% of stroke patients in the acute stage are accompanied by more than one complications. These complications affect not only the acute stage mortality but also the late stage rehabilitations. In Korea the oriental medicine is preformed in the treatment of stroke. Therefore it is important to recognize thoroughly the complications in the acute stage of stroke and to prevent them. But studies about complications of acute stage stroke is rarely presented in the fields of oriental medicine. So this study is prepared for investigating the characteristics and frequency of complications in the acute stage of stroke. And we are to assess the importance of theses acute complications by systemic reviewing the previous studies. Methods : Fifty one patients are included who had been admitted to ICU(intensive care unit) of Chenju Hospital of Wonkwang Oriental Medicine. Twenty nine patients are diagnosed as ischemic stroke and twenty one patients are diagnosed hemorrhagic stroke. Medical and neurological complications were investigated retrospectively based on medical notes excluding primary symptoms of stroke Le. motor weakness, sensory disturbance and speech disorder. And risk factors of stroke such as D.M. or hypertension are excluded. Results : Medical complications are more frequent than neurological ones. Most frequent medical complication is dysuria(61%) and constipation(45%), fever(30%) and aspiration pneumonia(22%) are followed in order of frequency. In Neurological complication dysphagia(56%), the exacerbation of infarction due to increased intracranial pressure(24%), irritability or insomnia(21%) is most frequently complicated in order of frequency. Conclusions : These complications are mostly caused by bed rest state in acute stage stroke. It is supposed that more aggressive management can prevent theses ones. And it is possible to improve the medical and neurological conditions by sticking theses study results.
