Sandifer syndrome is a rare manifestation of gastroesophageal reflux in children, occurring in association with abnormal movement of the head and neck and recurrent episodes of seizure after feeding. This syndrome may be misdiagnosed as infantile seizure and musculoskeletal disorder and may be associated with failure to thrive, anemia, aspiration pneumonia, and esophagitis. In this paper, Sandifer syndrome in a four months old male with recurrent aspiration pneumonia, apnea, and seizure after feeding is presented.

PURPOSE: This study aimed to evaluate whether prophylactic extended-field pelvic radiotherapy (EF-PRT) yields better results than standard whole pelvic radiotherapy (WPRT) in patients with pelvic lymph node-positive cervical cancer treated with concurrent chemoradiotherapy (CCRT). MATERIALS AND METHODS: A total of 126 cases of stage IB-IVA cervical cancer that had pelvic lymph node involvement in magnetic resonance imaging and were treated with CCRT between 2000 and 2016 were reviewed. None of the patients had paraaortic lymph node (PALN) metastases. The patients were classified to two groups, namely, those treated with EF-PRT, including prophylactic para-aortic radiotherapy, and those treated only with WPRT. The median dose to the PALN area in patients treated with EF-PRT was 45 Gy. All patients received concurrent cisplatin-based chemotherapy. RESULTS: Overall, 52 and 74 patients underwent EF-PRT and WPRT, respectively. Patient characteristics and irradiated dose were not significantly different, except the dose to the para-aortic area, between the two groups. The median follow-up period was 75.5 months (range, 5 to 195 months). The 10-year cumulative recurrence rate of PALN for EF-PRT vs. WPRT was 6.9% and 10.1% (p = 0.421), respectively. The 10-year disease-free survival and overall survival for EF-PRT vs. WPRT were 69.7% vs. 66.1% (p = 0.748) and 71.7% vs. 72.3% (p = 0.845), respectively. Acute gastrointestinal complications were significantly higher in EF-PRT (n = 21; 40.4%) than WPRT (n = 26; 35.1%) (p = 0.046). Late toxicities were not significantly different in both groups. CONCLUSION: In this study, prophylactic radiotherapy for PALN does not have an additional benefit in patients with pelvic lymph node-positive cervical cancer treated with CCRT.

PURPOSE: To evaluate the axial displacement of implant-abutment assembly after cyclic loading in internal tapered connection system. MATERIALS AND METHODS: External butt-joint connection implant and internal tapered connection implant were connected with three types of abutment for cement-retained prostheses, i.e. external type abutment (Ext group), internal tapered 1-piece abutment (Int-1 group), and internal tapered 2-piece abutment (Int-2 group). For each group, 7 implants and abutments were used. The implantabutments assemblies were clamped into the implant holder for vertical loads. A dynamic cyclic loading was applied for 150 +/- 10 N at a frequency of 4 Hz. The amount of axial displacement of the abutment into the implant was calculated at each cycle of 0, 5, 10, 50, 100, 1,000, 5,000, and 10,000. A repeated measures analysis of variance (ANOVA) for the overall effect of cyclic loading and the pattern analysis by linear mixed model were used for statistical analysis. Differences at P<.05 were considered statistically significant. RESULTS: The mean axial displacement after 10,000 cycles were 0.714 +/- 0.488 microm in Ext group, 5.286 +/- 1.604 microm in Int-1 group, and 11.429 +/- 1.902 microm in Int-2 group. In the pattern analysis, Int-1 and Int-2 group showed continuous axial displacement at 10,000 cycles. There was no declining pattern of axial displacement in the Ext group. CONCLUSION: The pattern of linear mixed model in Ext group showed no axial displacement. There were continuous axial displacements in abutment-implant assemblies in the Int-1 and Int-2 group at 10,000 cycles. More axial displacement was found in Int-2 group than in Int-1 group.

PURPOSE: To evaluate the role of standard axial MR images for the diagnosis of meniscal tears of the knee. MATERIALS AND METHODS: Forty-five patients with a prior MRI examination that underwent arthroscopic surgery of the knee due to clinical impression of a meniscal tear were included in the study group. The sequence for meniscal evaluation was an axial fat-saturated proton density-weighted image with a 4 mm slice thickness. Axial MR images were independently reviewed by two radiologists and were compared with findings of arthroscopy. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of the axial MR scan for the diagnosis of the meniscal tear were calculated. RESULTS: A total 90 menisci of 45 patients were evaluated in the axial MR scans. Forty-two patients had meniscal tears, and two of the patients had tears in both menisci; thus, a total of44 meniscal tears were found by arthroscopy. For meniscal tears, the sensitivity of the axial plane was 76.2%, the specificity was 89.1% and the accuracy was 81.1%. False negative meniscal tears were seen in 12 cases and false positive meniscal tears were seen in 5 cases on the axial MR images. CONCLUSION: In standard knee MRI examinations, axial images may be valuable for the detection and localization of meniscal tears.

Cervical large cell neuroendocrine carcinoma is rare. We experienced one case of cervical large cell neuroendocrine carcinoma with invasive mucinous adenocarcinoma in 49 years old woman. So we report the case and brief review of literature.

Although Cesarean section (CS) itself has contributed to the reduction in maternal and perinatal mortality, an undue rise in the CS rate (CSR) has been issued in Korea as well as globally. The CSR in Korea increased over the past two decades, but has remained at approximately 36% since 2006. Contributing factors associated with the CSR in Korea were an improvement in socio-economic status, a higher maternal age, a rise in multiple pregnancies, and maternal obesity. We found that countries with a no-fault compensation system maintained a lower CSR compared to that in countries with civil action, indicating the close relationship between the CSR and the medico-legal system within a country. The Korean government has implemented strategies including an incentive system relating to the CSR or encouraging vaginal birth after Cesarean to decrease CSR, but such strategies have proved ineffective. To optimize the CSR in Korea, efforts on lowering the maternal childbearing age or reducing maternal obesity are needed at individual level. And from a national view point, reforming health care system, which could encourage the experienced obstetricians to be trained properly and be relieved from legal pressure with deliveries is necessary.

Visual disturbances are common among women with pre-eclampsia. The obstetricians should have an understanding of the various conditions associated with visual impairments. We report a case of Purtscher-like retinopathy developed after pre-eclampsia combined with acute pancreatitis. A 33-year-old primigravida with twin pregnancy was admitted to the department of obstetrics and gynecology for preterm labor and pre-eclampsia at 36+4 weeks gestation. After a cesarean section, she complained of abdominal pain and visual acuity loss. She was diagnosed with Purtscher-like retinopathy combined with acute pancreatitis after ophthalmologic examination and an abdominal computed tomography scan. Purtscher-like retinopathy, most often observed after trauma, is very rare in pre-eclampsia. In addition, while visual disturbances from other conditions are transient, it can result in persistent visual impairments. Thus, when a patient with pre-eclampsia complains of visual problems for a long period of time, obstetricians should consider an ophthalmologic evaluation and treatments during the earliest stage of the disease.
