The pattern of thickening of the extrahepatic bile duct on computed tomography was analysed in 30 cases with recurrent pyogenic cholangitis diagnosed by surgery (n=19) or clinical basis (n=11). The mean wall thickness of the extrahepatic bile duct was 3.3mm (range, 1-6.3mm). Diffuse thickening of the extrahepatic bile ductal wall was demonstrated in 26 of 30 cases. Diffuse thickening of the extrahepatic bile duct in recurrent pyogenic cholangitis may be differentiated from focal thickening of duct in a common duct cancer or pancreatic cancer.

The 12th rib syndrome is a disease that causes pain between the upper abdomen and the lower chest. It is assumed that the impinging on the nerves between the ribs causes pain in the lower chest, upper abdomen, and flank. A 74-year-old female patient visited a pain clinic complaining of pain in her back, and left chest wall at a 7 on the 0-10 Numeric Rating scale (NRS). She had a lateral fixation at T12-L2, 6 years earlier. After the operation, she had multiple osteoporotic compression fractures. When the spine was bent, the patient complained about a sharp pain in the left mid-axillary line and radiating pain toward the abdomen. On physical examination, the 10th rib was not felt, and an image of the rib-cage confirmed that the left 10th rib was severed. When applying pressure from the legs to the 9th rib of the patient, pain was reproduced. Therefore, the patient was diagnosed with 9th rib syndrome, and ultrasound-guided 9th and 10th intercostal nerve blocks were performed around the tips of the severed 10th rib. In addition, local anesthetics with triamcinolone were administered into the muscles beneath the 9th rib at the point of the greatest tenderness. The patient's pain was reduced to NRS 2 point. In this case, it is suspected that the patient had a partial resection of the left 10th rib in the past, and subsequent compression fractures at T8 and T9 led to the deformation of the rib cage, causing the tip of the remaining 10th rib to impinge on the 9th intercostal nerves, causing pain.

Ketamine is used widely in emergency departments for a variety of purposes, including procedural sedation for facial laceration in pediatric patients. The major benefits are its rapid onset of effects, relatively short half-life, and lack of respiratory depression. The known side effects of ketamine are hallucinations, dizziness, nausea, and vomiting. Seizure is not a known side effect of ketamine in patients without a seizure history. Here, we present the case of a patient in whom ketamine likely induced a generalized tonic-clonic seizure when used as a single agent in procedural sedation for facial laceration repair. The aim of this article is to report a rare and unexpected side effect of ketamine used at the regular dose for procedural sedation. This novel case should be of interest to not only emergency physicians but also plastic surgeons.

This paper presents our clinical experiences for reconstruction of the linear depressed postburn scar band by rhombus subcutaneous pedicle skin flap (RSPF). We report new RSPF, it’s versatility, and effectiveness for correction of the mild to moderate linear depressed postburn scar band. To correct the postburn scar band, we have newly designed the Rhombus Subcutaneous Pedicle Skin Flap (RSPF), which is made as rhombus-shaped skin flap on the inside of scar band. After excision of burn scar band, the each vertex of RSPF flap is advanced into the skin defects at apex of extended skin incision, which is starting from the upper and lower portion of the removed burn scar band at a near right angle. This flap can add more extra skin to adjacent superior and inferior area of excised scar band. We have experienced 2 cases of RSPF for reconstruction of linear depressed postburn scar band deformities in lower extremity. After 3 weeks to 3 months postoperative follow ups, relatively satisfactory results were obtained in all cases. We had successfully reconstructed the linear depressed postburn scar postburn band of lower extremity using the rhombus subcutaneous pedicle skin flap. For the correction of mild to moderate sized linear depressed postburn scar band deformities in extremity, the RSPF is simple, and very effective without donor morbidity.

Purpose:
Due to rapid changes in the industrial structure in last decade, the wider various types of chemical agents were introduced. Burn surgeons should be well-informed with rapid changes of chemical burns. We present the recent incidence trends of causing agents of chemical burns.
Methods:
From 2010 to 2019, 92 chemical burn victims were included in this study. A retrospective study was made about the type, distribution and incidence of the causing agents of chemical burns. Initial treatments of most chemical burn wounds are copious saline irrigation by tap water, except hydrofluoric acid burn cases managed by 10% calcium gluconate injection. In alkali chemical burns on extremity, if thin eschars appear in postburn 2∼3 days, acute early surgical escharectomy and split thickness skin graft were done.
Results:
More than 9 types of major chemicals causing chemical burns were surveyed, and the most common causing agent of chemical burns was Hydrofluoric acid (23.9%) followed by Acetic acid (19.6%) and Sodium hydroxide (8.7%).
Conclusion
From 2010 to 2019, changes in the causing agent of chemical burns are that the types of major causing agents of chemical burns have increased and the distribution and incidence of causing agents have changed compared to previous reports. According to this study, more than 9 types of major chemicals causing chemical burns were surveyed, and the most common causing agent of chemical burns was Hydrofluoric acid (23.9%) followed by Acetic acid, Sodium hydroxide.

Primary biliary cirrhosis (PBC) is characterized by histological findings of an immunoinflammatory destruction of small- and medium-sized bile ducts with progressive portal fibrosis, and the presence of anti-mitochondrial antibody (AMA) with a laboratory evidence of chronic cholestasis. The term "autoimmune cholangitis" (AIC) is used for a disease with the clinical and pathologic features of primary biliary cirrhosis (PBC) but with negative AMA and positive anti-nuclear antibody (ANA) tests. Eight cases of AIC and ten cases of PBC were reviewed in order to determine whether there was any difference between two diseases in clinico-pathologic aspects. All of the patients were female and the mean ages of AIC and PBC patients were 48 and 47 years, respectively. ANA test was positive in six of ten PBC paients and their mean titer was lower than that of AIC patients. IgM level was significantly higher in PBC group than in AIC group. No significant difference was found between two groups with respect to biochemical and histopathological features. Since the only consistently distinguishing features between these two conditions are the autoantibody profile (AMA vs ANA) and immunoglobulin level (IgM), these two conditions might be part of a spectrum. PBC can be considered to be the same as AMA-positive AIC or alternatively AIC to be the same as AMA-negative PBC.

BACKGROUND: Acute renal failure(ARF) is characterized by rapid decline in glomerular filtration rate and retension of nitrogenous waste products. This syndrome occurs in approximately 5 percent all hospital admissions and up to 30 percent of admissions to intensive care units. ARF is diagnosed when screening of hospital patients reveals a recent increase in serum BUN(blood urea nitrogen) and creatinine. The mortality rate for ARF is approximate 40-60% and has changed little in past three decades. This lack of improvement in outcome, despite significant advances in medicine. The reasons of high mortality rate is not certain. This study intend to identify prognostic risk factors influencing survivals. METHODS: We retrospectively analyzed 60 patients with ARF during 2 years period from Oct. 1996 to Oct. 1998 at chosun university hospital. Multiple factors which may influence mortality were evaluated. RESULTS: 1)Of the 60 patients, 34 were male and 26 were female. The mean age was 55.8+/-15.9 years. 2)The cause of ARF is Drug, toxin, dehydration, infection, trauma, surgery, urinary tract obstruction, HFRS, rhabdomyolysis and bleeding. 3)Underline disease is observed in 52 case. DM, Hypertension, Malignancy, Pulmonary disease, Liver disease, Renal disease 4)The mortality rate is 31.7%. The major cause of deaths is DIC, infection and hepatic failure. 5)Based on the unpaired t-test, chi-squre analysis, albumin, total bilirubin, hemoglobin, thrombocytopenia, APACHE II score, serum sodium, urine creatinine, number of multiple organ failure, cause of acute renal failure, pH, vital sign on admission, sepsis, DIC, oilguria, and hemodialysis were significant factors between survivors and nonsurvivors(p< 0.05). 6)APACHE II score on admission is good prognostic factor for patients with acute renal failure (p<0.001). CONCLUSION: This results suggest that the evaluation of patients symptom, sign, laboratory data, APACHE II score is important for patients with acute renal failure. the discriminant score by multiple analysis and APACHE II score could relatively predict the mortality of ARF patients. however further evaluation and clinical apply of prognostic factors is required to confirm these results.
