The importance of anaplastic lymphoma kinase (ALK) as an oncogene in non-small cell lung cancer (NSCLC) has emerged as a major concern due to a dramatic clinical effect of targeted therapy. As compared with the research for targeted therapy, the study about clinicopathological characteristics for ALK positive NSCLC hasn't been worked enough. Here, we describe a 35-year-old woman diagnosed with stage IVb NSCLC with ALK rearrangement. During evaluating her disease, a metastatic lesion to uterine cervix was found. Although lung cancer metastasis to female genital tract is rare, we also present case series that show a metastasis to the female genital tract in NSCLC with ALK rearrangement. These case series could suggest that ALK positive NSCLC has distinct metastatic pattern.

Magnetic Resonance Image (MRI) has been used as a safe, conventional and harmless diagnostic tool. However, thermal injuries have frequently been reported during MRI scanning due to the heat generated by the reaction with the magnetic field. It is recommended that metal-containing monitoring devices such as pulse oximetry and ECG monitoring leads should be removed prior to the start of the MRI scan, but these monitoring devices are inevitably placed in children or patients in the intensive care unit who have low compliance with the scan. Since the interaction between the metal probe or wire loop of pulse oximetry and the magnetic field can result in high thermal conduction, full-thickness burn can occur over the entire body surface during the MRI examination. Several cases of thermal burns from pulse oximetry on the fingers have been reported. However, we present a case of a full-thickness burn arising left earlobe in a 2-month-old child caused by the high conduction heat from pulse oximetry metal probe.

This study was performed to evaluate the feasibility of ultrasound-guided computed tomography (CT) cholecystography and to establish an optimal protocol. In 8 healthy beagles, CT cholecystography was conducted using four contrast formulas; two dilution ratios (1:1 vs. 1:3) and two total volumes (8 mL vs. 16 mL) of 300 mgI/kg iohexol after ultrasound-guided percutaneous contrast injection into the gallbladder. CT images were obtained at 3, 10, and 30 min after injection and assessed qualitatively and quantitatively. For all contrast formulas, CT cholecystography showed the gallbladder and the intra- and extrahepatic bile ducts. The volume of the gallbladder and size of bile duct were significantly larger when using a volume of 16 mL iohexol than an 8 mL volume regardless of the dilution ratio. The distinction between the common bile duct and duodenum, the filling of the gallbladder, and the patency of bile duct were effectively assessed using a 16 mL volume of contrast agent with either dilution ratio. Beam-hardening artifacts deteriorated CT image quality for visualizing the biliary system when using the dilution ratio of 1:1. Patency of the bile tract could be easily evaluated using a curvilinear planar reconstruction. There was no significant difference in CT scan time among the different conditions. Minor leakage of contrast agent temporarily occurred after contrast injection in 30% of 32 sets of CT cholecystography. Ultrasound-guided percutaneous cholecystography can visualize both gallbladder and biliary tract with minimal artifacts using a contrast agent volume of 16 mL with a 1:3 dilution ratio.

Infections are a major complication in burn patients. In particular, in immunocompromised patients, burn wounds are prone to infections due to destroyed cutaneous barriers and a weakened immune response. It is critical for physicians to monitor infections during burn treatment, since infections can disturb the healing process. It can be challenging to identify the causative microorganism and implement proper treatment for infected burn wounds. Bacterial infections such as impetigo are the most commonly reported, followed by fungal and viral infections. Human herpes virus is one of the most frequent viral infections that complicate burn patients’ recovery. Cases of varicella-zoster virus (HHV-3) infection among pediatric burn patients or reactivation in major burn patients in intensive care units have been reported in the literature. Herein, we present a case where HHV-3 reactivation was promptly detected during the treatment of a facial scald burn.

Purpose: Electric scooters have recently entered into wide use in South Korea because of their eco-friendliness and convenience. Associated accidents resulting in friction burns are also increasing, due to a lack of recognition of the regulations regarding drivable roads and speed limits. We present the clinical characteristics of friction burns induced by electric scooters.M ethods: We retrospectively evaluated the clinical records of 48 patients who visited our institution after accidents involving electric scooters from January 2018 to February 2022. Demographic data, including age, sex, time of the accident, the type and location of the friction burn, and associated injuries, were reviewed. Results: The age of the patients ranged from 15 to 51 years. The most common injuries were superficial partial-thickness dermal burns, while 14 cases involved deep partial-thickness dermal burns. Multifocal injuries were present in a single patient in most cases. The face was the most commonly affected region, followed by the knees. The average treatment period was 13.0 days, but the follow-up period was longer in patients with facial bone fractures or other comorbidities. Conclusion Friction burns from electric scooters are increasing, but their clinical presentation and related statistics have not been reported yet. Since most patients were not injured or had only mild epidermal burns in regions with enough clothing, appropriate safety equipment can prevent burns from electric scooters. However, once accidents occur, patients often present with multiple other injuries in the extremities, so proper injury evaluation and management should be emphasized for shorter hospitalization and optimal outcomes.

BACKGROUND/AIMS: Globus is a persistent or intermittent non-painful sensation of a lump or foreign body in the throat and a commonly encountered clinical condition. We aim to evaluate the prevalence of gastroesophageal reflux disease (GERD) and to determine the parameters for predicting the response to treatment with proton pump inhibitor (PPI) using wireless pH monitoring in patients with globus sense. METHODS: We retrospectively reviewed the medical records of 37 patients with atypical GERD symptoms. A total of 27 patients with dominant globus sense were enrolled. Endoscopic examination and 48-hour wireless esophageal pH monitoring were performed, and the patients underwent a therapeutic trial of full dose PPIs daily over a period of 4 weeks. RESULTS: Both typical and atypical GERD symptoms co-existed in 14 patients (51.9%, 14/27). According to ROME III criteria, 19 patients (70.4%, 19/27) were diagnosed as GERD. Twelve patients (44.4%, 12/27) were PPI responders. A significant difference in the frequency of symptom index (+) or symptom associated probability (+) was observed between the PPI responder group and the non-responder group (p<0.01). CONCLUSIONS: In patients with globus sense, 70.4% were diagnosed with GERD. Symptom index/symptom associated probability in wireless ambulatory pH monitoring was a good objective parameter for PPI responder.

Background: This phase 3 study evaluated the efficacy and safety of 6-month treatment with romosozumab in Korean postmenopausal women with osteoporosis. Methods: Sixty-seven postmenopausal women with osteoporosis (bone mineral density [BMD] T-scores ≤–2.5 at the lumbar spine, total hip, or femoral neck) were randomized (1:1) to receive monthly subcutaneous injections of romosozumab (210 mg; n=34) or placebo (n=33) for 6 months. Results: At month 6, the difference in the least square (LS) mean percent change from baseline in lumbar spine BMD (primary efficacy endpoint) between the romosozumab (9.5%) and placebo (–0.1%) groups was significant (9.6%; 95% confidence interval, 7.6 to 11.5; P<0.001). The difference in the LS mean percent change from baseline was also significant for total hip and femoral neck BMD (secondary efficacy endpoints). After treatment with romosozumab, the percent change from baseline in procollagen type 1 N-terminal propeptide transiently increased at months 1 and 3, while that in C-terminal telopeptide of type 1 collagen showed a sustained decrease. No events of cancer, hypocalcemia, injection site reaction, positively adjudicated atypical femoral fracture or osteonecrosis of the jaw, or positively adjudicated serious cardiovascular adverse events were observed. At month 9, 17.6% and 2.9% of patients in the romosozumab group developed binding and neutralizing antibodies, respectively. Conclusion Treatment with romosozumab for 6 months was well tolerated and significantly increased lumbar spine, total hip, and femoral neck BMD compared with placebo in Korean postmenopausal women with osteoporosis (ClinicalTrials.gov identifier NCT02791516).
