  • Although midgut volvulus is clinically characterized by bilous vomiting and abdominal distention, plain abdominal X-ray is usually non-specific and therefore it can be misdiagnosed to other diseases. Upper gastrointestinal contrast study and computed tomography have been used as a routine diagnostic tool but it takes cost and time. Abdominal ultrasonography is a relatively good alternatives in diagnosing midgut volvulus and it relatively saves cost and time. But case presentation of midgut volvulus diagnosed with abdominal ultrasonography are rarely found in literature. We experienced a 6 month old girl who had come to our hospital with bilous vomiting and was diagnosed as midgut volvulus with ultrasonography. Thus we report this case with the presentation of typical ultrasonographic findings of midgut volvulus.

  • Sigmoid volvulus may cause acute or subacute colonic obstruction. Excessive length of the sigmoid colon may be a contributing factor. Typically, the patient develops bilious vomiting and marked gaseous abdominal distension. We report a case of sigmoid volvulus in a 9-year-old boy who presented with recurrent, sudden onset abdominal pain, abdominal distension, and vomiting for 1 year, which was diagnosed by simple abdominal X-ray, barium enema, computed tomography, and colonoscopic examination. Colonoscopic reduction failed and a sigmoid colectomy with primary repair was performed. The intra-operative findings showed that the sigmoid colon was noted to be dilated, and redundant with a lax mesentery. Two clear areas of compression (proximal and distal) were present. After sigmoidectomy, the symptoms resolved. After 5 years of follow-up, he had no new symptoms.

  • Purpose: Focused Assessment with Sonography for Trauma (FAST) provides an important initial screening examination in adult trauma patients. However, due to its low sensitivity, FAST is not a replacement for computed tomography (CT) in hemodynamically stable trauma patients. The aim of this study was to determine the test characteristics of FAST in adult, hemodynamically stable, blunt abdominal trauma patients by using a critical action as a reference standard. Methods: The medical records for FAST examination at a single hospital from January 2009 to February 2011 were retrospectively reviewed. The inclusion criterion was isolated, hemodynamically stable, blunt abdominal trauma. Hemodynamically unstable patients or patients with penetrating injuries were excluded. The reference standard was the presence of a critical action, which was defined as one of the following: 1) operative intervention for a finding discovered on CT, 2) interventional radiology for bleeding, 3) transfusion of 2 or more packed RBCs, or 4) death at the emergency department. Results: There were 230 patients who met the inclusion criterion. There were 20 true positive, 206 true negative, 0 false positive, and 4 false negative results. The sensitivity and the specificity were 83% and 100%, respectively. Conclusion: Despite its low sensitivity for detecting any abnormal finding discovered on CT, negative FAST could aid to exclude critical action in hemodynamically stable, blunt abdominal trauma patients.

  • The prevalence of obesity has noticeably increased worldwide over several decades with various complication. Even though anti-obesity drug treatments have been spotlighted by resulting in effective mean weight losses, its adverse effects cannot be overlooked. Thus, this study aimed to evaluate the effects of multi-frequency whole body vibration, one of the mechanical stimulus, as a countermeasure against obesity. Thirty-two-6-week-old C57BL/6J male mice were equally assigned to four groups: the Control group (CON, n = 8), the Sham group (Sham, n = 8), the sham with single frequency whole body vibration (S+V, n = 8), and the sham with multi frequency whole body vibration (S+MV, n = 8). After 4 weeks, morphologic changes in the adipose tissue were evaluated from three-dimensional images using in vivo micro-computed tomography. At 4 weeks, the volume of the abdominal adipose tissue, which had the highest value in Sham group, noticeably reduced in S+MV group compared to it in S+V group. These results implied that the accumulation of abdominal adipose tissue can be effectively reduced through applying multi-frequency whole body vibration.

  • Paragonimiasis is a parasitic disease caused by Paragnonimus species. The primary site of infection is the lung, and extrapulmonary involvement is also reported. When infected with Paragonimus westermani, which is the dominant species in Korea, the central nervous system is frequently involved along with the liver, intestine, peritoneal cavity, retroperitoneum, and abdominal wall. Ectopic paragonimiasis raises diagnostic challenge since it is uncommon and may be confused with malignancy or other inflammatory diseases. Here, we report an ectopic paragonimiasis case initially presented with recurrent abdominal pain. The patient developed abdominal pain 3 times for the previous 3 years and the computed tomography (CT) of the abdomen revealed fluid collection with wall enhancement. Recurrent diverticulitis was initially suspected and part of the ascending colon was resected. However, the specimen showed intact colon wall without evidence of diverticulitis and multiple parasite eggs and granulomas were found instead. The size of about $70{\mu}m$, the presence of an operculum and relatively thick egg shell suggested eggs of Paragonimus species. With appropriate exposure history and a positive antibody test, the definitive diagnosis was made as peritoneal paragonimiasis.

  • The aim of this study is to develop a 3D registration algorithm for positron emission tomography/computed tomography (PET/CT) and magnetic resonance (MR) images acquired from independent PET/CT and MR imaging systems. Combined PET/CT images provide anatomic and functional information, and MR images have high resolution for soft tissue. With the registration technique, the strengths of each modality image can be combined to achieve higher performance in diagnosis and radiotherapy planning. The proposed method consists of two stages: normalized mutual information (NMI)-based global matching and independent component analysis (ICA)-based refinement. In global matching, the field of view of the CT and MR images are adjusted to the same size in the preprocessing step. Then, the target image is geometrically transformed, and the similarities between the two images are measured with NMI. The optimization step updates the transformation parameters to efficiently find the best matched parameter set. In the refinement stage, ICA planes from the windowed image slices are extracted and the similarity between the images is measured to determine the transformation parameters of the control points. B-spline. based freeform deformation is performed for the geometric transformation. The results show good agreement between PET/CT and MR images.

  • A 67-year-old male presented with left temporal hemianopsia and left hemiparesis. A contrast-enhanced magnetic resonance image revealed a $4.5{\times}3.5{\times}5.0cm$ rim-enhancing mass with central necrosis and associated edema located in the left occipital lobe. Of positron emission tomography and abdominal computed tomography, a 9-cm mass with poor enhancement was found in the right hepatic lobe. Craniotomy and right hemihepatectomy was performed. The resected specimen showed histological features and immunochemical staining consistent with a metastatic neuroendocrine tumor (NET). Four months later, the tumors recurred in the brain, liverand spinal cord. Palliative chemotherapy with etoposide and cisplatin led to complete remission of recurred lesions, but the patient died for pneumonia. This is the first case of a metastatic brain NET originating from the liver. If the metastatic NET of brain is suspicious, investigation for primary lesion should be considered including liver.

  • Objectives: This is a five-year survival and complete response (CR) report on pancreatic cancer treated with western medicine and Korean traditional medicine. Method: A 59-year-old woman diagnosed with pancreatic cancer visited ○○ Korean traditional medicine hospital after neoadjuvant chemotherapy and pylorus-preserving pancreaticoduodenectomy. She was treated with Korean traditional medicine, including acupuncture, abdominal moxibustion, wild ginseng pharmacopuncture, and herbal medicine, which was based on integrated medicine therapy (IMT), from March 2018 to September 2022. The tumor size was measured by scanning with computed tomography (CT), magnetic resonance imaging, and positron-emission tomography/CT. Adverse events were evaluated using laboratory conclusion and National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Result: During four years and three months of treatment, IMT maintained safety. The patient finally reached five-year survival without any recurrence or complication (CR) on October 26, 2022. Conclusion: We suggest that an integrative approach including Korean traditional medicine can be a meaningful treatment option for pancreatic cancer. Further studies should be performed to establish the proper treatment protocol of integrative medicine for pancreatic cancer.

  • Pheochromocytomas and paragangliomas (PPGLs) may secrete hormones or bioactive neuropeptides such as interleukin-6 (IL-6), which can mask the clinical manifestations of catecholamine hypersecretion. We report the case of a patient with delayed diagnosis of paraganglioma due to the development of IL-6-mediated systemic inflammatory response syndrome (SIRS). A 58-year-old woman presented with dyspnea and flank pain accompanied by SIRS and acute cardiac, kidney, and liver injuries. A left paravertebral mass was incidentally observed on abdominal computed tomography (CT). Biochemical tests revealed increased 24-hour urinary metanephrine (2.12 mg/day), plasma norepinephrine (1,588 pg/mL), plasma normetanephrine (2.27 nmol/L), and IL-6 (16.5 pg/mL) levels. 18F-fluorodeoxyglucose (FDG) positron emission tomography/CT showed increased uptake of FDG in the left paravertebral mass without metastases. The patient was finally diagnosed with functional paraganglioma crisis. The precipitating factor was unclear, but phendimetrazine tartrate, a norepinephrine-dopamine release drug that the patient regularly took, might have stimulated the paraganglioma. The patient's body temperature and blood pressure were well controlled after alpha-blocker administration, and the retroperitoneal mass was surgically resected successfully. After surgery, the patient's inflammatory, cardiac, renal, and hepatic biomarkers and catecholamine levels improved. In conclusion, our report emphasizes the importance of IL-6-producing PPGLs in the differential diagnosis of SIRS.

  • A 10-year-old female Pomeranian weighing 2.25 kg with a history of gradual weight loss and an intraabdominal mass confirmed with ultrasonography at a local hospital was referred to the Veterinary Medical Teaching Hospital, Jeju National University. Physical examination revealed abdominal distention. Blood analysis revealed hypoglycemia (57 mg/dL; reference range, 60-110 mg/dL). On abdominal ultrasonography, a heterogeneously hyperechoic mass measuring 7.51 × 10.6 cm was found at the level of the left kidney. Computed tomographic findings showed a unilateral left kidney mass with a 10-cm diameter and vessel contrast enhancement in the corticomedullary phase. Unilateral nephrectomy and ovariohysterectomy were performed because left ovary enlargement was observed during surgery. The renal mass was adjacent to the aorta and vena cava and attached to a portion of the small intestine, greater omentum, and left ovary. The mass was huge (12.5 × 10 × 7 cm) and was 16.5% of the body weight. Histopathological examination revealed renal cell carcinoma (RCC) and ovarian metastasis. After surgery, clinical signs improved remarkably, and serum glucose level returned to normal. As RCC is resistant to radiation and chemotherapy, the owner decided not to proceed with postoperative adjunctive therapies. To the best of our knowledge, this is the first case report of ovarian metastasis with huge RCC in a dog.
