  • Diabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. Type 1 diabetes, or juvenile-onset diabetes, results from a cellular-mediated autoimmune destruction of the ${\beta}$-cells of the pancreas. Type 2 diabetes, or adult-onset diabetes, is a term used for individuals who have insulin resistance, a condition that makes it harder for the cells to properly use insulin, and usually have relative insulin deficiency. The diabetes causes the onset of chronic complications and diabetic neuropathy is one of the most debilitating complications. In this study, the hypoglycemic effect and the preventive effect of diabetic complications of Dioscorea rhizoma extract(DRE) were examined in rodent model. We investigated the glucose tolerance test and long term hypoglycemic effect of DRE in Type 1 streptozotocin-induced diabetic rats and Type 2 diabetic db/db mice. DRE showed a hypoglycemic effect on blood glucose levels than that of control group in Type 1 streptozotocin-induced diabetic rats and Type 2 diabetic db/db mice. On the basis of our results, we conclude that long-term use of DRE might help decrease blood glucose level and prevention of diabetes-associated complication.

  • Purpose: The rectus abdominis musculocutaneous (RAM) flap has contributed to the efficient reconstruction of soft tissue defects. The flap has the advantage of easy dissection, minimal donor site morbidity, and the constant vascular anatomy with long pedicle. Authors used the free RAM flap to reconstruct multi-located soft tissue defects while still considering functionality and aesthetics. We present the long-term outcomes and versatility of free RAM flaps. Materials and Methods: From 1994 to 2004, all patients who underwent soft tissue reconstruction with free RAM flap were reviewed retrospectively. The site of the reconstruction, vessels of anastomosis, type of RAM flap, and outcomes, including flap success rate, hospital stay after flap transfer, conduction of secondary procedure, flap complications, and donor-site complications were analyzed. Results: Twenty-one patients underwent 24 free RAM flaps in site of breast, face, upper extremity and lower extremity. Mean follow-up period was 36.1 months (range, 3~156 months). The overall success rate was 92% with only a loss of 2 flaps. Minor complications related to transferred flaps were necrosis of 2 partial flaps, hematoma formation in 3 cases, and a wound infection in 1 case. Donor site morbidity was not observed. Debulking surgery was performed in 4 patients, and scar revision was performed in 3 patients. Conclusion: Free RAM flap is a workhorse flap for general soft-tissue reconstruction with minimal donor site morbidity with aesthetically good results. Thus, the free RAM flaps are versatile, and sturdy for any sites of soft-tissue where reconstruction could be performed.

  • Purpose: Several risk factors related with chronic complications and mortality related with liver injury of mushroom poisoning were reported. But, there were few reports about the long term outcomes. The aim was to evaluate the long term clinical outcomes in mushroom poisoning regarding the risk factors. Methods: Clinical data were reviewed and outcomes were evaluated with medical records and/or telephone interviews. The patients who had one or more risk factors such as markedly elevated aspartate aminotransferase (AST) or alanine aminotransferase (ALT), prolonged prothrombin time (PT) were classified into high risk group. Patients had no risk factor classified into low risk group. Results: From June 1989 to December 2003, nineteen mushroom poisoning patients admitted to Asan Medical Center, seven were male, and mean age was $58\pm9$ years old. All the patients accidentally ingested and the interval from ingestion to symptom onset was $9\pm4$ hours. There were four patients in high risk group, and fifteen in low risk group. In high risk group, peak AST was $2,263.3\pm1,303.0IU/L$most prolonged PT was $38.0\pm27.4\%$, and stuporous mental status was shown in one patient. In low risk group, laboratory values returned to the normal values but histological evaluation revealed specific features of toxic hepatitis on sixth hospital day. Chronic complications such as persistent or chronic hepatitis, mortality was not occurred during follow up period (from 10 months to 16 years) in both groups. Conclusion: Although the number of patients were small, there were no chronic complications or mortality related with liver injury after mushroom poisoning regardless risk factors of chronic complications and mortality.

  • Background The ideal vaginoplasty must be successful functionally as well as have a natural appearance, and also must retain its functionality and appearance over the long term. Conventional vaginoplasty techniques have functional limitations and are associated with recurrent complications, but rectosigmoid vaginoplasty is known to have a high satisfaction rate due to its functional similarity with the vagina. We conducted the present study to assess the usability of rectosigmoid vaginoplasty over the course of long-term follow-up. Methods From March 1992 to February 2014, 84 patients were treated with rectosigmoid vaginoplasty; 44 had gender identity disorder, 29 had vaginal agenesis, 8 had female pseudohermaphroditism, and 3 had gynecologic malignancies after radical pelvic surgery. This retrospective study was based on a review of the patients' records, clinical examinations, complications, and questionnaires about appearance, function, and sexual intercourse. Results All patients who underwent rectosigmoid vaginoplasty were discharged within 2 weeks without surgical flap loss. The early complications were partial flap necrosis, difficulty in defecation, mucous hypersecretion, and postoperative ileus. The late complications were vaginal introitus contracture, vaginal prolapse, and difficulty in urination. The mean length and diameter of the neovagina 3.4 years after rectosigmoid vaginoplasty were 13.2 cm and 3.8 cm, respectively. On questionnaires about satisfaction, 70% of patients reported excellent satisfaction, 11% good, 12% fair, and 7% poor. Conclusions Rectosigmoid vaginoplasty is useful, safe, and well-accepted operative method with good functional and cosmetic results, such as natural lubrication and adequate vaginal length and width obtained without requiring the use of a dilator.

  • Background: A significant proportion of cardiac surgery intensive care unit (CSICU) patients require long-term ventilation, necessitating tracheostomy placement. The goal of this study was to evaluate the long-term postoperative outcomes and complications associated with percutaneous dilatational tracheostomy (PDT) in CSICU patients. Methods: All patients undergoing PDT after cardiac, thoracic, or vascular operations in the CSICU between January 1, 2013 and January 1, 2021 were identified. They were evaluated for mortality, decannulation time, and complications including bleeding, infection, and need for surgical intervention. Multivariable regression models were used to identify predictors of early decannulation and the complication rate. Results: Ninety-three patients were identified for this study (70 [75.3%] male and 23 [24.7%] female). Furthermore, 18.3% of patients had chronic obstructive pulmonary disease (COPD), 21.5% had history of stroke, 7.5% had end-stage renal disease, 33.3% had diabetes, and 59.1% were current smokers. The mean time from PDT to decannulation was 39 days. Roughly one-fifth (20.4%) of patients were on dual antiplatelet therapy and 81.7% had anticoagulation restarted 8 hours post-tracheostomy. Eight complications were noted, including 5 instances of bleeding requiring packing and 1 case of mediastinitis. There were no significant predictors of decannulation prior to discharge. Only COPD was identified as a negative predictor of decannulation at any point in time (hazard ratio, 0.28; 95% confidence interval, 0.08-0.95; p=0.04). Conclusion: Percutaneous tracheostomy is a safe and viable alternative to surgical tracheostomy in cardiac surgery ICU patients. Patients who undergo PDT have a relatively short duration of tracheostomy and do not have major post-procedural complications.

  • Background: Long-term comparisons of phacoemulsification with topical medication are limited in canine diabetic cataracts. Objectives: To compare outcomes of eyes submitted to phacoemulsification with those of topical medication for canine diabetic cataracts and identify risk factors for complications. Methods: Through medical records review, 150 eyes (76 dogs) with diabetic cataracts were included; 58 eyes (31 dogs) underwent phacoemulsification (phaco-group) and 92 eyes (48 dogs) received ophthalmic solution alone (medication-group). The medication-group was divided into owner-led and vet-led groups depending on who elected not to perform surgery. Comparisons involved time-to-complications, vision, and the number and type of ophthalmic solutions administered. The association between complications and pretreatment clinical findings was investigated. Results: No difference was found in complication risk between the phaco and owner-led medication groups. Conversely, the vet-led medication-group had a higher complication risk than the other groups. At the last follow-up, 94.8% of the phaco-group had vision, whereas 7.6% of the medication-group restored some visual axis. Poor glycemic control in the medication-group and younger age in the phaco-group increased complication risk. At 1-year post-treatment, the average number of ophthalmic solutions administered was 1.7 and 2.6 in the phaco and medication groups, respectively. The medication-group used anti-inflammatories the most throughout the follow-up, whereas the phaco-group used anti-inflammatories the most until 1-year post-treatment and lacrimostimulants at 1.5-year post-treatment. Conclusions: For canine diabetic cataracts, phacoemulsification is recommended because it is superior to topical management alone in terms of maintaining vision and reducing the number of ophthalmic solutions required in the long term.

  • Kawasaki disease is a systemic vasculitis of unknown etiology, usually occurring in infants and young children. Although the etiology of Kawasaki disease remains uncertain, its serious complicationssuch as giant aneurysm formation, coronary arterial stenotic lesions, and thrombotic occlusionhave been proven to cause myocardial ischemia or infarction in patients with Kawasaki disease. To prevent and treat these complications, several modes of therapyincluding long-term anticoagulation, interventional catheterization, and surgical treatmenthave been gradually developed. In this article, we review the cardiovascular complications following Kawasaki disease and the management thereof, which includes thrombolytic therapy, catheter intervention, and coronary artery bypass graft.

  • Though complications of foreign bodies in the esophagus are rare, they are sometimes fatal due to injuries to the esophageal wall by sharp pieces of bone, metals, long-term lodgement of foreign bodies in the esophagus or a little inadvertence during diagnostic or therapeutic esophagoscopy on patients with esophageal diseases. Therefore, failure to early diagnose and adequately treat the complications will lead to high morbidity and mortality. The authors have experienced 21 cases of complications of foreign bodies in the esophagus caused by foreign bodies themselves or inadvertence during esophagoscopy. So we report them with literature review.

  • Oral cancer is a malignant neoplasm of the lips or oral cavity. Surgery, radiotherapy and chemotherapy depending on the location and stage of the tumor can be considered as important treatment modalities of oral cancer. Unfortunately, all three treatments can have both acute and chronic complications. Among them, trismus and osteoradionecrosis (ORN), unique complications of radiotherapy in the orofacial region, are particularly difficult to treat once manifested. Therefore, these two complications of radiotherapy have devastating effects on the patient's oral health and furthermore, overall quality of life. In this study, we present a case of a patient showing trismus and ORN following radiotherapy for the treatment of maxillary squamous cell carcinoma and briefly discuss this matter of trismus and ORN in the perspective of a dentist.

  • Purpose: To evaluate long-term local control rate and toxicity in patients treated with external beam radiotherapy (EBRT) for pituitary adenomas. Materials and Methods: We retrospectively reviewed the medical records of 60 patients treated with EBRT for pituitary adenoma at Korea University Medical Center from 1996 and 2006. Thirty-five patients had hormone secreting tumors, 25 patients had non-secreting tumors. Fifty-seven patients had received postoperative radiotherapy (RT), and 3 had received RT alone. Median total dose was 54 Gy (range, 36 to 61.2 Gy). The definition of tumor progression were as follows: evidence of tumor progression on computed tomography or magnetic resonance imaging, worsening of clinical sign requiring additional operation or others, rising serum hormone level against a previously stable or falling value, and failure of controlling serum hormone level so that the hormone level had been far from optimal range until last follow-up. Age, sex, hormone secretion, tumor extension, tumor size, and radiation dose were analyzed for prognostic significance in tumor control. Results: Median follow-up was 5.7 years (range, 2 to 14.4 years). The 10-year actuarial local control rates for non-secreting and secreting adenomas were 96% and 66%, respectively. In univariate analysis, hormone secretion was significant prognostic factor (p = 0.042) and cavernous sinus extension was marginally significant factor (p = 0.054) for adverse local control. All other factors were not significant. In multivariate analysis, hormone secretion and gender were significant. Fifty-three patients had mass-effect symptoms (headache, dizziness, visual disturbance, hypopituitarism, loss of consciousness, and cranial nerve palsy). A total of 17 of 23 patients with headache and 27 of 34 patients with visual impairment were improved. Twenty-seven patients experienced symptoms of endocrine hypersecretion (galactorrhea, amenorrhea, irregular menstruation, decreased libido, gynecomastia, acromegaly, and Cushing's disease). Amenorrhea was abated in 7 of 10 patients, galactorrhea in 8 of 8 patients, acromegaly in 7 of 11 patients, Cushing's disease in 4 of 4 patients. Long-term complication was observed in 4 patients; 3 patients with cerebrovascular accident, 1 patient developed dementia. Of these patients, 3 of 4 received more than 60 Gy of irradiation. Conclusion: EBRT is highly effective in preventing recurrence and reducing mass effect of non-secreting adenoma. Effort to improve tumor control of secreting adenoma is required. Careful long-term follow-up is required when relatively high dose is applied. Modern radiosurgery or proton RT may be options to decrease late complications.
