OBJECTIVES: This study investigated whether long-acting injectable (LAI) paliperidone is different from its oral form in terms of the effect on cognitive function in schizophrenia spectrum and other psychotic disorders. METHODS: We reviewed the medical records of patients in Seoul National University Bundang Hospital who were diagnosed as having schizophrenia and/or other psychotic disorders based on DSM-5 from 2016 to 2017. Seven patients were treated with oral paliperidone and 11 were treated with paliperidone palmitate. All patients underwent clinical and neuropsychological assessment, including the Korean version of the MATRICS Consensus Cognitive Battery (MCCB) at their first visit or within one month of their initial treatment. MCCB was repeated within three to 12 months after the initial assessment. RESULTS: There was no significant difference between the two groups in most cognitive domains including speed of processing, attention and vigilance, working memory, verbal learning, visual learning and reasoning and problem solving domain. However, patients treated with paliperidone palmitate showed better improvement in social cognition domain than those taking oral paliperidone. The standardized values of social cognition domain scores had significantly improved over time in patients under paliperidone palmitate, demonstrating a significant time-by-group interaction. CONCLUSION: Our results show that long-acting injectable paliperidone could be helpful in some aspects of improving cognitive function in schizophrenia spectrum and other psychotic disorders. Further studies with other antipsychotics are necessary to generalize the results.

Purpose: Distinguishing a fever caused by infection from the necessary febrile response in injured patients is difficult, because trauma patients often have concomitant obvious infectious origins. In traumatic brain injury, early fever might be associated with worse clinical outcomes; however, few reports on trauma patients without brain injury are available.
Methods: In this retrospective observational study, consecutive trauma patients without brain injury who were admitted to the surgical intensive care unit during a 3 year period were included. The surgical and clinical outcomes were compared according to body temperature. Locally weighted scatterplot smoothing was used to identify the relationship between body temperature and injury severity.
Results: A total of 111 patients were included. Body temperature increased as the injury severity score increased up to 47.717, above which it decreased. Mortality was high in hypothermic patients (72.7%; p < 0.001); however, few differences were observed between normothermic and hyperthermic patients (3.5% and 2.4%, respectively). The nonsurvivors had lower body temperatures on the 1st and 2nd days after admission (36 ˚C and 36.9 ˚C) compared with the survivors (37.3 ˚C and 37.7 ˚C; p < 0.001 and p = 0.006). In severely injured patients, low levels of inflammatory biomarkers and low body temperature were correlated with mortality.
Conclusions Fever in trauma patients without brain injury is correlated with injury severity but not with prognosis. Hypothermia on the 1st and 2nd days after admission was significantly correlated with mortality. In severely injured patients, a decreased inflammatory response might play a certain role in promoting a high mortality rate.

This report is a clinical review of 298 cases of early gastric cancer that were treated at Kosin Medical Hospital during 8 years from 1984 to 1992. In 1962, the Japanese Gastroenterological Endoscopy Society defined early gastric cancer as a lesion confined to the mucosa or submucosa and not related to the presence of lymph-node metastasis. The prognosis for early gastric cancer (EGC) is generally excellent, but the proportion of EGC cases progressing to advanced gastric cancer is steadily increasing nowadays. The presence or absence of lymph-node metastasis in EGC is an important prognostic factor; in other words, the survival rate or recurrence rate of node-negative EGC is known to be much better than that of node-positive EGC. The incidence of EGC among resected gastric cancers was 14.7%, and has been increasing annually. The mean age of the EGC patient was 52.4 years, and the most common type was IIc. The size of the lesion was variable, but the most common range was 1~3 cm. Lymph-node metastasis accurred more frequently with the larger sized lesions. In this study, several factors such as age, sex, tumer location, tumer size, depth of invasion, macroscopic and histologic type were evaluated to determine frequency of lymph node metastasis. In the analysis of these eight facters, sex, tumer size, depth of invasion and Lauren type were statistically correlated with lymp node metastasis.

Surgeons occasionally encounter a patient with a gastric cancer invading an adjacent organ, such as the pancreas, liver, or transverse colon. Although there is no established guideline for treatment of invasive gastric cancer, combined resection with radical gastrectomy is conventionally performed for curative purposes. We recently treated a patient with a large gastric cancer invading the abdominal wall, which was initially diagnosed as a simple abdominal wall abscess. Computed tomography showed that an abscess had formed adjacent to the greater curvature of the stomach. During surgery, we made an incision on the abdominal wall to drain the abscess, and performed curative total gastrectomy with partial excision of the involved abdominal wall. The patient received intensive treatment and wound management postoperatively with no surgery-related adverse events. However, the patient could not receive adjuvant chemotherapy and expired on the 82nd postoperative day.

Gastric necrosis due to gastric outlet obstruction is a very rare condition, but it might be fatal if missed or if diagnosis is delayed. Our patient was a 73-year-old male complaining of abdominal pain, distension and dyspnea for 1 day. In plain radiography and computed tomography, a markedly distended stomach and decreased enhancement at the gastric wall were noted. He underwent explo-laparotomy, and near-total gastric mucosal necrosis accompanied by sludge from the soaked laver was noted. A total gastrectomy with esophagojejunostomy was performed, and he recovered without sequelae. Final pathologic examination revealed advanced gastric cancer at the antrum with near-total gastric mucosal necrosis.

PURPOSE: The postoperative treatment after appendectomy is usually decided on the basis of the surgeons' intraoperative findings. Comparatively, the pathologic diagnosis of appendicitis is confirmed several days after the surgery; therefore, it usually does not affect the postoperative treatment strategy. The aim of this study was to investigate the discrepancies between the surgical and pathologic diagnoses of appendicitis and to identify their clinical implication. METHODS: A retrospective observational study was performed in 1,817 patients who underwent 3-port laparoscopic appendectomy for the final diagnosis of appendicitis. The clinical variables that could estimate the severity of appendicitis and the intensity of postoperative treatment were analyzed and compared according to the surgical and pathologic diagnoses. RESULTS: Of 1,321 cases of surgically simple appendicitis, 254 (29.3%) were pathologically complicated appendicitis. On the other hand, 221 of 496 cases (44.5%) of surgically complicated appendicitis were pathologically simple. Neither the surgical nor the pathologic diagnosis of appendicitis affected the development of postoperative intra-abdominal abscess (P = 0.079 for surgical diagnosis; P = 0.288 for pathologic diagnosis); however, the surgical diagnosis showed more correlation with the severity of disease and the intensity of the treatment pathway than did the pathologic diagnosis. CONCLUSION: There were discrepancies between the surgeons' intraoperative assessment and the pathologists' final histologic diagnosis of appendicitis. The surgeon's classification might be more predictive of the outcome than the pathologist's because only the surgeon's findings are available immediately after surgery.

PURPOSE: This study aimed to evaluate the clinical course and prognostic factors of acquired third, fourth, and sixth cranial nerve (CN) palsy grouped according to etiology. METHODS: This study involved a retrospective review of the medical records of 153 patients who were diagnosed with acquired paralytic strabismus from January 2004 to July 2015. Outcomes, recovery rates, and time to recovery were investigated according to the affected CN: CN3, CN4, and CN6 palsies. The patients were classified into four groups based on etiology: idiopathic, traumatic, neoplastic, and vascular. RESULTS: The mean age of the patients was 59.8 ± 14.5 years and the mean follow-up period was 10.8 months. Out of the 153 patients, 63 (41.2%) had CN3 palsy, 35 (22.9%) had CN4 palsy, and 55 (35.9%) had CN6 palsy. The most common causes were vascular related (54.9%), followed by idiopathic (28.1%), trauma (8.5%), and neoplasm (5.88%). About 50% of the patients recovered within six months. Among the four etiologic groups, the idiopathic group showed the best prognosis because about 50% of the patients in this group recovered within three months. This was followed by the vascular, traumatic, and neoplastic groups. Cox proportional hazard analysis revealed a significant association between the baseline prism diopter and recovery rate. CONCLUSIONS: The prognosis and natural history of paralytic strabismus vary depending on its cause. The vascular group had the best recovery rate and shortest recovery time, whereas the neoplastic group required the longest time to recover.

PURPOSE: To evaluate the efficacy of focal verteporfin photodynamic therapy (PDT) in patients diagnosed with chronic central serous chorioretinopathy (CSC).METHODS: This study enrolled 52 eyes of 52 patients with chronic CSC who had received verteporfin PDT. The laser spot size of 26 eyes covering only the localized hyperfluorescent area in indocyanine green angiography was classified as focal PDT. The PDT spot size of the other 26 eyes covered the total area of retinal pigment epithelial detachment including the leaking point and was defined as conventional PDT. The central subfield thickness and subfoveal choroidal thickness were measured using Heidelberg Spectralis optical coherence tomography before PDT and at months 1, 3, 6, and 12 after PDT.RESULTS: The mean spot size of the PDT was 1,995 µm in the focal group and 2,995 µm in the conventional group. Central subfield thickness steadily decreased in both groups. The mean baseline subfoveal choroidal thickness for the two groups was 334.95 and 348.35 µm, respectively, with no significant difference (p = 0.602). Subfoveal choroidal thickness decreased significantly to 304.20 µm at 1 month, 284.85 µm at 3 months, 271.60 µm at 6 months, and 265.95 µm at 12 months in the focal group (p < 0.001, p < 0.001, p < 0.001, and p < 0.001, respectively, compared with baseline). In the conventional group, subfoveal choroidal thickness decreased significantly to 318.75, 300, 284, and 272 µm at 1, 3, 6, and 12 months, respectively (p < 0.001, p < 0.001, p < 0.001 and p < 0.001 compared with baseline). There were no significant differences between the two groups in subfoveal choroidal thickness based on PDT spot size at 1, 3, 6, and 12 months (p = 0.633, p = 0.625, p = 0.676, and p =0.755, respectively).CONCLUSIONS: Focal verteporfin PDT for CSC significantly decreased the subretinal fluid and sufoveal choroidal thickness to the same extent as conventional PDT.

Objective: We investigated whether the addition of Alzheimer’s disease-signature region cortical thickness (AD-Ct) and hippocampal volume (Hv) obtained from brain MRI to subjective memory complaints and informant-reports of cognitive decline enhances the screening accuracy for cognitive disorders in a memory clinic setting. Methods: 120 participants (40 cognitively normal, 40 MCI, 40 dementia) underwent clinical evaluation, neuropsychological assessment, and brain MRI. The Subjective Memory Complaints Questionnaire (SMCQ) and Seoul Informant-Report Questionnaire for Dementia (SIRQD) were applied to assess subjective memory complaints and informant-reports of cognitive decline respectively. Logistic regression and ROC curve analyses were conducted to compare the screening abilities of SMCQ+SIRQD, SMCQ+SIRQD+Hv, and SMCQ+SIRQD+AD-Ct models for cognitive disorders. Results: SMCQ+SIRQD+Hv model indicated better screening accuracy for MCI and overall cognitive disorder (CDall) than SMCQ+ SIRQD model. SMCQ+SIRQD+AD-Ct model had superior screening accuracy for dementia in comparison to SMCQ+SIRQD model. ROC curve analyses revealed that SMCQ+SIRQD+Hv model had the greatest area under the curve (AUC) for screening MCI and CDall (AUC: 0.941 and 0.957), while SMCQ+SIRQD+AD-Ct model had the greatest AUC for screening dementia (AUC: 0.966). Conclusion Our results suggest that the addition of regional quantitative MRI data enhances the screening ability of subjective memory complaints and informant-reports of cognitive decline for MCI and dementia.
