Significance of Perianal Lesion in Pediatric Crohn Disease / 대한소아소화기영양학회지

PURPOSE: Despite the increasing incidence of pediatric Crohn disease (CD) in Korea, data on the characteristics of perianal lesions are scarce. Therefore, we aimed to investigate the characteristics of pediatric CD with accompanying perianal lesions in Korea. METHODS: We retrospectively reviewed the medical records of children (age ≤18 years) with confirmed CD at Gachon University Gil Medical Center between 2000 and 2014. Patients were classified into two groups based on the presence or absence of any perianal lesions including skin tags. Additional analysis was performed according to the presence or absence of perianal perforating lesions. RESULTS: Among the 69 CD children (mean age, 15.4 years) include in the analysis, 54 (78.3%) had a perianal lesion and 29 (42.0%) had a perianal perforating lesion. The median duration of chief complaints was longer in pediatric CD with any accompanying perianal lesions (5.40 months vs. 1.89 months, p=0.02), while there was no difference between pediatric CD with and without perianal perforating lesions (5.48 months vs. 4.02 months, p=0.18). Perianal symptoms preceded gastrointestinal symptoms in 13 of 29 (44.8%) patients with perianal perforating lesions. CONCLUSIONS: CD should be suspected in children with perianal lesions, even in circumstances when gastrointestinal symptoms are absent.

Characteristics of Upper Gastrointestinal Tract Involvement in Korean Pediatric Crohn's Disease: A Multicenter Study / 대한소아소화기영양학회지

PURPOSE: Crohn's disease (CD) can involve any site of the gastrointestinal tract (GIT). However, the characteristics of upper GIT involvement in CD are unclear, especially in the Eastern pediatric population. This study aimed to estimate the prevalence of upper GIT involvement and identify the clinical features of Korean children with CD. METHODS: This was a retrospective multicenter cohort study that included 52 pediatric patients with CD who underwent esophagogastroduodenoscopy and biopsy. The clinical symptoms and endoscopic and histologic features of the upper GIT were identified according to the presence or absence of upper gastrointestinal symptoms. RESULTS: Among the 52 patients, upper GIT involvement was noted in 50.0% (26/52). The mean age at CD diagnosis was 14.1±2.1 years. Gastric ulcer was the most common lesion (19.2%) found on upper GIT endoscopy, followed by duodenal ulcers (15.4%). Chronic inflammation was the most common histopathologic feature (75.0%), followed by gastric erosion (17.3%). Granuloma was found in 9.6% of patients. Helicobacter pylori infection was identified in 5.8% of patients. Endoscopic and histologic findings were not significantly different, but the mean values of erythrocyte sedimentation rate (60.7±27.1 vs. 43.0±27.6 mm/h, p=0.037) and C-reactive protein (16.5±28.2 vs. 6.62±13.4 mg/dL, p=0.014) were significantly different between patients with and without upper gastrointestinal CD symptoms. CONCLUSION: Upper GIT involvement was relatively common in pediatric patients with CD irrespective of upper gastrointestinal symptoms, and H. pylori infection was relatively uncommon. The results of this study should aid the establishment of regional guidelines for upper GIT examination.

Vertebroplasty of compression fracture with prevertebral hematoma during treatment of postherpetic neuralgia: A case report

Postherpetic neuralgia (PHN) and vertebral compression fracture (VCF) are common causes of chronic pain in the elderly population. Careful history taking and imaging studies are needed for diagnosis when both diseases coexist. Vertebroplasty is a clinically efficient surgical treatment of VCF, while nerve block and/or medications are the mainstay of PHN pain control. The most serious complications of vertebroplasty are pulmonary embolism or neurologic deficit due to cement leakage. An 80-year-old female patient was diagnosed with PHN of the right L1 dermatome; however, her pain expanded to the midback and subcostal area. Thoracic magnetic resonance imaging and abdominal computed tomography revealed recent L2 compression fracture with prevertebral hematoma caused by cortical bone defect of the L2 body. Even though the risk of cement leakage was high, L2 vertebral body augmentation was performed using a bone filler device and high-viscosity cement; this treatment was successful, without cement leakage or any other complications.

Clinical performance comparison of I-gel insertion by anesthesiology residents versus novice clinicians

BACKGROUND: I-gel is a recently developed supraglottic airway device with many advantages. Like laryngeal mask airway (LMA), I-gel is an easier and quicker intubation alternative to endotracheal intubation in certain situations. In this study, we assessed the ease of I-gel insertion and compared the clinical performance of anesthetsiology residents (group R) experienced in endotracheal intubation versus that of interns (group I) with little intubation experience. METHODS: This prospective and randomized study included 60 patients. The ease of insertion, number of I-gel insertion attempts, presence of air leakage, and postoperative complications such as bleeding, dental trauma, hoarseness, and sore throat were evaluated in each group. RESULTS: Insertion was successful on the initial attempt in 29 of 30 cases in group R. In group I, 24 initial insertions were successful. The mean insertion times were 12.5 +/- 4.8 and 27.9 +/- 12.5 seconds for group R and group I, respectively (P < 0.001). No significant differences were observed between the two groups regarding postintubational air leakage. Regarding complications, two cases of bleeding, one case of dental trauma, and two cases of sore throat were recorded. No significant differences were observed between the two groups for any of the complications examined. CONCLUSIONS: I-gel is a suitable alternative insertion device that enables rapid and easy intubation by physicians who are experienced with endotracheal intubation. Moreover, this device also enables efficient and safe insertion during emergent situations for novice clinicians, even those who have little experience in intubation.
