Intraperitoneal air in pancreatic pseudocysts is a rare complication that can jeopardize hemodynamic stability and requires emergency surgery. A 61-year-old man was admitted to our hospital after abdominal pain, vomiting and diarrhea. Computed tomography showed a hollow visceral perforation with intraperitoneal air and two pseudocysts close to the pancreas. The patient was transferred to the emergency operating room with symptoms of septic shock. We histopathologically diagnosed a ruptured pancreatic pseudocyst combined with an intracystic haemorrhage. We resected a portion of the pseudocyst wall using surface electrocautery inside the lumen, cholecystectomy and peritoneal toilet and maintained adequate external drainage. The patient was discharged on postoperative Day 12. The patient achieved relapse-free survival for 12 months postoperatively. Ruptured pancreatic pseudocysts with extraluminal gas are dangerous if effective medical interventions are not performed. Emergency surgery should be completed as soon as possible to drain the pancreatic cyst and cleanse the abdomen.

Objectives We aimed to provide the Asian experience with the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) in pediatric thyroid nodules. Methods Consecutive thyroid fine-needle aspirates (patient age, ≤18 years) were retrospectively collected from 7 tertiary centers in 5 Asian countries. Results Of 194,364 thyroid aspirates, 0.6% were pediatric cases (mean age, 15.0 years). Among 827 nodules with accessible follow-up, the resection rate and risk of malignancy (ROM) were 36.3% and 59.0%, respectively. Malignant nodules (n = 179) accounted for 59.7% of resected nodules and 21.6% of all thyroid nodules with available follow-up. Compared with the published adult series, pediatric nodules had a higher resection rate and ROM, particularly in the indeterminate categories. Conclusions Our study demonstrates that Asian pediatric thyroid nodules had higher ROM than those from adults. The prototypic outputs of TBSRTC may need to be adjusted in the pediatric population.

Improvement to the image of fractured granite basements is among the most sought-after goals for processing seismic data in Cuu Long basin, the most proliferous petroleum basin. Unlike a clear layering structure of the sediment, fuzzy images of the granite basement are often the source of confusion for interpreters to identify which structures are presented inside it. In such a low signal to noise ration (SNR) environment, extracting geological information such as fault systems and fracture becomes challenging. In this study, diffraction imaging is employed in an effort to identify and enhance the fault system inside the basement. The comparison of the study result with various standard post-stack attribute approaches shows the effectiveness of the diffraction imaging method.

This paper aims to determine the rate of epidermal growth factor receptor (EGFR) gene mutations in advanced and metastatic squamous cell lung cancer in Vietnamese patients. EGFR mutation testing was performed on 559 formalin-fixed paraffin-embedded tissue samples from advanced and metastatic squamous cell lung cancer patients by real-time PCR. The results showed that EGFR mutations were found in 8.4%. Most of them were exon 19 deletions, approximately 51.1%. Multivariate analysis showed that EGFR mutations were more prevalent in gender (p<0.0001). In conclusion, EGFR mutation testing should be performed in patients with squamous cell lung cancer. Keywords: Lung squamous cell carcinoma, EGFR gene.
