Holoprosencephaly is a rare malformation complex or development defect including different degrees of incomplete cleavages of the embryonic prosencephalon and varying degrees of the midface defects, resulting from the defect of prechordal mesoderm, migrating forward into the area anterior to the notochord during the third week of fetal development. Early antenatal diagnosis of holoprosencephaly is important to find out its severity, to predict its prognosis, and to determine proper management according to its prognosis and severity. The possibility of early antenatal diagnosis of holoprosencephaly by ultrasound has been suggested, but occasionally missed and rarely confirmed. We present one case of lobar holoprosencephaly, diagnosed postnatally and one case of alobar holoprosencephaly, diagnosed antenatally in our hospitals.

PURPOSE: To confirm the effect of the frog leg lateral radiographs for determining the clinical indication of total hip arthroplasty for high riding dislocation and to discuss its theoretical background. MATERIALS AND METHODS: A consequent series of reconstructive THA were studied in 28 recent tuberculous hips. Twenty-three hips (17patients) with developmental dysplastic hip were compared. Preoperatively, frog-leg lateral radiographs were performed in all the patients, which were enhanced using a 2-dimensional computer model to predict the reattachment of the greater trochanter. RESULTS: The modified scores of Merle d'aubigne and Postel improved from a mean of 2.6 points preoperatively to a mean of 5.1 points. Sciatic nerve palsies occurred in three cases. In two cases, they fully recovered, but in one case, it did not. We confirmed that old high dislocation of the hip could be adopted in type 1 and 2 categories of frog leg lateral position. The reconstruction of hip was relatively simple in type 3, however, further study is necessary in type 5 due to unsuitable abduction contracture. CONCLUSION: We confirm that frog leg lateral radiography is effective for determining the operative indication of high riding dislocation. However irreducible frog leg lateral position is absolutely contraindirated for total hip arthroplasty.

Percutaneous endoscopic gastrostomy (PEG) has become a widely used and safe method for long-term enteral feeding in patients who are unable to tolerate oral feeding. Although a number of complications can occur following PEG placement, most of these complications are not life threatening. Serious complications occur rarely after this procedure and they include peritonitis, visceral perforation, major gastrointestinal bleeding, and necrotizing fasciitis. An esophageal perforation following PEG placement is very rare and predisposing factors include Zenker's or epiphrenic esophageal diverticuli, esophageal strictures, and mass lesions. We recently experienced a case of distal esophageal perforation following a PEG tube change. The predisposing esophageal perforation factor in this case was uncertain, and we successfully treated the patient with surgical intervention.

Central nervous system (CNS) myelomatosis, which is the presence of monoclonal plasma cells in the cerebrospinal fluid (CSF), is extremely rare. We report a case of CNS myelomatosis developed in a 45-year-old woman with multiple myeloma in complete response, which was achieved by allogeneic peripheral blood stem cell transplantation using a reduced-intensity conditioning regimen consisting of melphalan, fludarabine, and antithymocyte globulin. Two months after the transplant, she developed a moderate motor and sensory weakness in both lower extremities. Atypical plasma cells were found in the CSF, and immunofixation revealed monoclonal light chain in the CSF. She was given three courses of weekly intra-thecal chemotherapy consisting of methotrexate, cytarabine, and dexamethasone, which cleared the CSF. This case indicates that the allogeneic transplantation could not control CNS myelomatosis, despite successfully treating the bone marrow myeloma.

Endoscopic ultrasonography-guided intervention has gradually become a standard treatment for peripancreatic fluid collections (PFCs). However, it is difficult to popularize the procedure in Korea because of restrictions on insurance claims regarding the use of endoscopic accessories, as well as the lack of standardized Korean clinical practice guidelines. The Korean Society of Gastrointestinal Endoscopy (KSGE) appointed a Task Force to develope medical guidelines by referring to the manual for clinical practice guidelines development prepared by the National Evidence-Based Healthcare Collaborating Agency. Previous studies on PFCs were searched, and certain studies were selected with the help of experts. Then, a set of key questions was selected, and treatment guidelines were systematically reviewed. Answers to these questions and recommendations were selected via peer review. This guideline discusses endoscopic management of PFCs and makes recommendations on Indications for the procedure, pre-procedural preparations, optimal approach for drainage, procedural considerations (e.g., types of stent, advantages and disadvantages of plastic and metal stents, and accessories), adverse events of endoscopic intervention, and procedural quality issues. This guideline was reviewed by external experts and suggests best practices recommended based on the evidence available at the time of preparation. This will be revised as necessary to address advances and changes in technology and evidence obtained in clinical practice and future studies.

There are diverse ring-like narrowings in the lower esophagus: mucosal ring, muscular ring, ring-like annular peptic stricture. Esophageal muscular ring is extremely rare and generally asymptomatic. It occurs at the proximal border of the esophageal vestibule that corresponds to the upper end of the lower esophageal sphincter. We experienced a case of lower esophageal muscular ring with a symptom of intermittent mild dysphagia for 40 years and report the findings with a review of the literature.
