Chronic actinic dermatitis was recently proposed as a syndrome including photosensitive eczema, photosensitivity dermatitis, actinic reticuloid, and persistent light reactivity. It is defined on the basis of 3 criteria, including clinically persistent eczematous eruption on sun-exposed skin, histologically consistent with chronic eczema, and photobiologically decreased MED to UVB. We report herein a 61-year-old man presented with 2-year history of erythematous to brownish lichenified papules and plaques on sun-exposed areas and shown decreased minimal erythema doses to both UVB and UVA. Biopsy specimen showed consistent with chronic eczema. He was treated with topical therapies of topical steroids and intralesional injection of triamcinolone, and oral anti-histamine, with avoidance of exposure to sun.

Development of biliary casts is very unusual, especially in patients who have not undergone liver transplantation. Variable causes of biliary cast formation in nonliver transplantation patients have been suggested. However, stasis of bile flow and/or gallbladder hypocontractility is known to eventually result in the promotion of biliary sludge and subsequent cast formation. Here we present one case of biliary cast syndrome, which developed in a nonliver transplant patient who had biliary sludge for a long period of time, providing evidence that long-standing biliary sludge may lead to cast formation.

Rice allergen has low antigenicity, and thus, anaphylactoid reactions to rice are exceedingly rare. We experienced a case of isolated rice allergy in a 5 month-old girl who had been fed a milk formula without incident. However, after feeding a powdered weaning milk formula containing rice, she developed symptoms of projectile vomiting and diarrhea, at this time rice specific antigen tests were all negative. One month later a challenge test was performed using a rice gruel, and her symptoms recurred. Endoscopic and microscopic findings showed hyperemic mucosa in the duodenum and subtotal villous atrophy. Thereafter, she showed no adverse reaction to almost all foods appropriate for her age, but after feeding rice gruel at 10 months, she developed symptoms of cyanosis and vomiting. However, none of the allergic symptoms were demonstrated at 13 months upon repeated challenge test. Currently, she is 28 months old and tolerates all foods including rice.

BACKGROUND: We investigated the effects of a magnesium sulfate pretreatment on intubating conditions and cardiovascular responses during rapid sequence tracheal intubation (RSI) in this double-blind randomized study. METHODS: Adult patients (n = 154) were randomly allocated to a rocuronium-0.6, rocuronium-0.9, or magnesium group. The magnesium group was pretreated with 50 mg/kg MgSO4, and the other two groups received the same volume of isotonic saline. Anesthesia was induced with alfentanil, propofol, and either 0.6 mg/kg (rocuronium-0.6 and magnesium groups) or 0.9 mg/kg (rocuronium-0.9 group) rocuronium. An anesthesiologist, blinded to the group assignments, performed RSI and assessed the intubating conditions. Systolic arterial pressure (SAP) and heart rate (HR) were recorded before the magnesium sulfate or normal saline was administered, before anesthesia induction, before intubation, and every minute after intubation for 5 min. RESULTS: Airway features were similar among the three groups. The intubating conditions were improved significantly in the magnesium group (P < 0.001) compared with the other two groups. Significant increases in SAP at 1 min after intubation were observed in the rocuronium-0.6 and -0.9 groups when compared with the magnesium group (P < 0.05). HR was comparable among the three groups (P > 0.05). No hypertensive episode occurred during the immediate post-intubation period in the magnesium group (P = 0.001), and tachycardia occurred most frequently in the rocuronium-0.6 group (P < 0.05). CONCLUSIONS: MgSO4 administered prior to RSI using alfentanil, propofol, and rocuronium may improve intubating conditions and prevent post-intubation hypertension.

Many sedatives are used clinically and include benzodiazepines, barbiturates, antihistamines, propofol, and alpha-2-agonist. Benzodiazepines activate GABA neuronal receptors in the brain and present sedating, hypnotic, anxiolytic, amnestic, and anticonvulsant effects, but low analgesic effects. Propofol induce sedative, anxiolytic, and amnestic effects but no analgesic effects. However, risks such as cardiopulmonary instability and hypotension must be considered during administration. Dexmedetomidine is a high selective alpha-2 agonist and has many advantages as a sedative. Patients under dexmedetomidine sedation awaken easily and are more likely to be cooperative. Risk of respiratory depression and cardiopulmonary instability is low as well. Additionally, dexmedetomidine decreases amount of analgesic needed during and after surgery, presenting analgesic effects. Dexmedetomidine also decreases risk of delirium. However, bradycardia may occur and biphasic effects on blood pressure may be observed during beginning of administration. Because of lengthy symptom onset and offset time, physicians should carefully control administration at the beginning and end of dexmedetomidine administration. The purpose of this review is to evaluate the efficacy and availability of dexmedetomidine in various clinical fields including sedation for critically ill patients, regional anesthesia, monitored anesthesia care for some invasive procedures, stabilization of heart in cardiac surgery or endoscopic procedures.

This study was performed to investigate the significance of gastric juice analysis (GJA) as a diagnostic criterion of a positive challenge in a standard oral cow's milk challenge (OCC) to confirm typical cow's milk protein-induced enterocolitis (CMPIE). Data from 16 CMPIE patients (aged 14 to 44 days) were analyzed. A standard OCC was openly executed using 0.15 g/kg of protein. Three symptoms (vomiting, lethargy, and bloody or pus-like stool), and four laboratory findings (GJA [3 hr], changes in peripheral blood absolute neutrophil count [ANC] [6 hr], C-reactive protein [6 hr], and stool smear test for occult blood or leukocytes) were observed after OCC. Before OCC, baseline studies were conducted; a stool smear test, blood sampling, and GJA. Positive OCC results were; vomiting (87.5%) (observed 1-3 hr after OCC), lethargy (62.5%) (1-3 hr), bloody or pus-like stool (43.8%) (6-10 hr), abnormal GJA (93.8%), an ANC rise >3,500 cells/microliter (93.8%), and an abnormal stool smear test (75.0%). A single GJA test after a standard OCC is a sensitive diagnostic criterion of a positive challenge, and may provide an early confirmatory diagnosis of CMPIE. An investigation of positive OCC outcomes helps to find out a diagnostic algorithm of criteria of a positive challenge in CMPIE.

Duodenal tumors may pose diagnostic difficulties in asymptomatic young patients because the duodenum may be overlooked during routine upper gastrointestinal endoscopy and because duodenal tumors are rare and present non-specific signs and symptoms. Although adenomas are the most common duodenal tumors, adenocarcinoma arising from sporadic tubulovillous adenoma without familial adenomatous polyposis is an uncommon condition in young patients. In patients with sporadic duodenal adenomas, the prevalence of colorectal adenomas is higher than prevalence for the general population. Herein, we report the case of a 27-year male with adenocarcinoma arising from a sporadic tubulovillous adenoma of the duodenum. The tumor was completely resected by endoscopic resection. Synchronous colon adenoma was also detected and treated by endoscopic mucosal resection.

BACKGROUND/AIMS: Colorectal cancer (CRC) is one of the major causes of death and poses a major public health concern. The National CRC Screening Programme (NCSP) provides annual CRC screening using a fecal occult blood test for individuals >50 years of age since 2004. The purpose of the current study was to determine the outcomes and efficacy of a fecal immunochemical test (FIT) based on the NCSP in a quality-controlled university hospital setting. METHODS: We retrospectively reviewed the medical records and a standardized questionnaire from the NCSP of 3,852 individuals who underwent a FIT between March and December 2009. All of the subjects submitted a stool specimen for a FIT, while a double-contrast barium enema or colonoscopy was performed as a confirmatory examination for FIT-positive individuals. The CRC screening rate and rate of detection colorectal adenomas, advanced adenomas, and colorectal cancers by FIT were evaluated. RESULTS: The CRC screening rate with FIT was very high (72.3%), but the positive rate of detection by FIT was only 1.3%. The rate of detection for colorectal cancers, adenomas, and advanced adenomas by FIT was 0.08%, 0.39%, and 0.13%, respectively. The quantitative values of FIT in individuals with colorectal adenomas and cancers were significantly higher than other colorectal diseases. Men (P=0.001) and elderly individuals (P=0.039) were significantly more common in the FIT-positive group than the FIT-negative group. Approximately 28% of the subjects with FIT-positive tests did not receive a confirmatory examination. CONCLUSIONS: Although the FIT had a low rate of detection, the FIT was a useful screening tool for detection of CRC in the NCSP. It will be important to increase CRC screening rates and confirmatory examination rates.

PURPOSE: In the present study, factors related to the recurrence of breast ductal carcinoma in situ (DCIS) in Korean patients were identified, and the prognostic factors for each age group were explored.METHODS: The subjects were 226 patients who were diagnosed with DCIS by histopathologic examination, and the effect of representative prognostic factors that are known already, including estrogen receptor (ER), progesterone receptor (PR) and the human epidermal growth factor receptor 2 (HER2) status, Ki-67 levels, and adjuvant therapy on the recurrence of DCIS was analyzed by using the Cox proportional hazard model.RESULTS: Among the 226 subjects, 11 patients underwent the recurrence of breast cancer. The average follow-up period was 52.7±23.5 months. The average age of the subjects was 50.6±9.3 years. Among the DCIS patients, the recurrence of breast cancer was significantly higher in the ER negative patients and those who have a Ki-67 level over 20%. However, the PR and HER2 status did not significantly affect breast cancer recurrence. The result also showed that only ER negative was a significant factor before the age of 50 years and that only the Ki-67 level over 20% was a significant factor to the patients 50 years of age or older.CONCLUSION: DCIS patients should be appropriately treated and managed depending on their age and clinicopathological factors to prevent the recurrence of DCIS.
