Various anatomical defects have been described in the surviving twin who had a stillborn, macerated monozygotic co-twin with Disseminated Intravascular Coargulation. The etiology is thought to be placental transfer of emboli or thromboplastic material through placental vascular anastomoses. We experienced a case of monozygotic twin with deceased co-twin at 30 weeks of gestation and confirmed to have antenatal periventricular germinal matrix and intraventricular hemorrhage, multicystic periventricular leukomalacia and diffuse encephalomalacia by neurosonography on first day of life despite of no clinical evidence of brain damage. The pathologic findings of placenta revealed infarct with massive fibrin deposition. A brief review of related literature is presented.

Acute pancreatitis(AP) in children is not common but can be associated with severe morbidity rates and its diagnosis is often delayed. Thus, reported mortality rates range from 0 to 78%. We have treated 26 patients with AP from 5 to 17 years of age over the past 17 years. We are intended to assess the relevance of the prognostic criteria used to assess severity of adult AP and to review the etiology, clilical presentation, diagnosis, and management of AP in children. The authors retrospectively reviewed 26 children with AP managed in Kyung Hee University Hospital from 1978 to 1995. Among 26 patients with AP, male were 12, and female were 14. And the mean age of patients was 11.8 years. In 9(34.6 %), no definitive cause was identified. Common causes of AP were trauma(23.1 %) and biliary tract disease(23.l%). Other etiologies were viral infection(15.4%) and post ERCP(3.8%). The presenting features were abdominal pain(92.3%), vomiting(61.5%), fever(l9.2%), submandibular pain(l1.5%), and abdominal mass(7. 6%). Back pain was rare(3.8%). Abdominal ultrasonographic findings were abnormal in 10 of 16 patients(62.5%) and abdominal CT findings were abnormal for 9 of 9 patients(100%). Seventeen patients(65.3%) were managed conservatively, and nine patients(34.6%) required surgical treatment. There was no mortality. To evaluate the severity of disease, we used the Imrie prognostic criteria used to assess the severity in adult AP. The number of positive criteria was correlated to the duration of hospitalization(r2=0.91) but statistically insignificant(p > 0.05). But, the number of positive criteria was correlated to the operative incidence(r2 = 0.93) and statistically significant(p < 0.05). The common causes of AP in children were unkown origin(34.6%), trauma(23.l %), and bili.ary tract disease(23.1 %). Ultrasonography and computed tomography were useful imaging tools of AP in children. The Imrie criteria used to evaluate the severity in adult AP were suspected to be valuable to asssess the severity of AP in children.

BACKGROUND/AIMS: The efficacy of standard triple therapy (STT) in treating Helicobacter pylori infection has decreased. Many investigators have attempted to increase the eradication rate. We investigated the outcomes of concomitant therapy (CT) and STT combined with probiotics (STP) as a first-line treatment for H. pylori infection. METHODS: We reviewed the medical records of 361 patients who received either STP (n=286) or CT (n=75). The STP group received STT combined with a probiotic preparation for 1 week. The CT group received STT and metronidazole for 1 week. RESULTS: The intention-to-treat and per-protocol eradication rates were 83.6% (95% confidence interval [CI], 79.0 to 87.7) and 87.1% (95% CI, 81.2 to 89.7) in the STP group and 86.7% (95% CI, 78.7 to 93.3) and 91.4% (95% CI, 83.6 to 97.1) in the CT group (p=0.512 and p=0.324), respectively. The frequency of adverse effects was higher in the CT group (28.2%) than in the STP group (12.8%) (p=0.002). CONCLUSIONS: STP and CT are encouragingly efficacious as first-line treatments for H. pylori infection. Therefore, adding probiotics to STT may be a feasible option to avoid side effects.

Purpose:
Cone beam computed tomography (CBCT) is widely used to evaluate the temporomandibular joint (TMJ). For the three-dimensional (3D) assessment of the TMJ, segmentation of the mandibular condyle and articular fossa is essential. This study aimed to perform deep learning-based 3D segmentation of the mandibular condyle on CBCT images and evaluate the performance of the segmentation.
Methods:
CBCT scan data from 99 patients (mean age: 53.3±19.2 years) diagnosed with TMJ disorders were analyzed. From the CBCT images, sagittal, coronal, and axial planes showing the mandibular condyle were selected and combined to form two-dimensional (2D) images. The U-Net deep learning model was used to exclusively segment the mandibular condyle area from the 2D images. From these results, 3D images of the mandibular condyle were reconstructed. Accuracy, precision, recall, and the Dice coefficient were calculated to appraise segmentation performance in each plane.
Results:
The average Dice coefficient was 0.92 for the coronal and axial planes and 0.82 for the sagittal plane. The CBCT image-based segmentation performance of the mandibular condyle in the coronal and axial planes exceeded that in the sagittal plane. The sharpness and uniformity of the 2D images affected segmentation performance, with segmentation errors more likely occurring in non-uniform images. Certain segmentation errors were corrected through software processing. Finally, the segmented mandibular condyle images were applied to the CBCT data to reconstruct a 3D TMJ model.
Conclusions
Mandibular condyle 3D segmentation on CBCT images using U-Net may help evaluate and diagnose TMJ disorders. The proposed segmentation method may assist clinicians in efficiently analyzing CBCT images, particularly in cases involving anatomical abnormalities.

Collagenous colitis is an uncommon condition charaeterized clinically by diarrhea and weight loss and histologically by thickening of the subepithelial collagen band with chromic inflammation. Laboratory tests of blood, urine and stool, and colonscopic findings are usually normal. The etiology of collagenous colitis is unknown. We report a case of collagenous colitis improved after treatment with sulfasalazine with review of literatures.
