Hyponatremia is frequently seen in intracranial hemorrhagic patients and has been often attributed to inappropriate secretion of antidiuretic hormone. But in recent years, a number of studies have shown that hyponatremia in many patients with intracranial disease may actually be caused by cerebral salt wasting (CSW) syndrome and circulating Atrial natriuretic peptide (ANP) and Brain natriuretic peptide (BNP) are probably involved. This report describes a patient who developed bacterial meningites caused by pseudomonas aeruginosa and CSW syndrome after removal of pituitary adenoma. CSW syndrome resolved by fluid and salt replacement after 4 months.

BACKGROUND AND OBJECTIVES: Many neurologists are unaware of the drop attack that may occur from an inner ear dysfunction especially in elderly. We performed this study to investigate the clinical features and results of quantitative audiovestibular tests in six elderly patients (> or =65 years of age) who presented with drop attacks attributable to an inner ear pathology. MATERIALS AND METHOD:Group was divided into Meniere's syndrome (4) or non-Meniere peripheral vestibulopathy (2). Standard dizziness questionnaire and quantitative audiovestibular function testing were performed. RESULTS:Episodes were described as a sudden push to the ground in four or a violent illusionary movement of environment leading to a fall in two. All cases gave a history of prior vertiginous episodes and vestibular testing revealed unilateral caloric paresis. Ipsilateral hearing loss was documented in four cases. CONCLUSIONS:Our results suggest that otologic causes should be considered in the differential diagnosis of the drop attack in elderly, even if the symptoms and signs were not consistent with Meniere's syndrome.

PURPOSE: Laparoscopic gastrectomy is a widely accepted surgical technique. Recently, robotic gastrectomy has been developed, as an alternative minimally invasive surgical technique. This study aimed to evaluate the question of whether robotic gastrectomy is feasible and safe for the treatment of gastric cancer, due to its learning curve. MATERIALS AND METHODS: We retrospectively reviewed the prospectively collected data of 100 consecutive robotic gastrectomy patients, from November 2008 to March 2011, and compared them to 282 conventional laparoscopy patients during the same period. The robotic gastrectomy patients were divided into 20 initial cases; and all subsequent cases; and we compared the clinicopathological features, operating times, and surgical outcomes between the three groups. RESULTS: The initial 20 robotic gastrectomy cases were defined as the initial group, due to the learning curve. The initial group had a longer average operating time (242.25+/-74.54 minutes vs. 192.56+/-39.56 minutes, P>0.001), and hospital stay (14.40+/-24.93 days vs. 8.66+/-5.39 days, P=0.001) than the experienced group. The length of hospital stay was no different between the experienced group, and the laproscopic gastrectomy group (8.66+/-5.39 days vs. 8.11+/-4.10 days, P=0.001). The average blood loss was significantly less for the robotic gastrectomy groups, than for the laparoscopic gastrectomy group (93.25+/-84.59 ml vs. 173.45+/-145.19 ml, P<0.001), but the complication rates were no different. CONCLUSIONS: Our study shows that robotic gastrectomy is a safe and feasible procedure, especially after the 20 initial cases, and provides a satisfactory postoperative outcome.

PURPOSE: To describe the imaging findings of traumatic intracranial aneurysms (TICA) in children. MATERIALS AND METHODS: Five boys aged 3-15 (mean, 7) years with surgically confirmed TICA were included in this study. All had a history of nonpenetrating head trauma, and they underwent precontrast CT imaging immediately after the injury and follow-up CT or MRI. In all cases, angiography revealed the presence of aneurysms, which at surgery were shown to be pseudoaneurysms with severe adhesions. RESULTS: Angiography demonstrated that all aneurysms were located in the anterior cerebral artery (ACA) or its branches. The precise locations were the A2 segment of the ACA, the site of origin of the callosomarginal artery or its first branch, or of the anterior internal frontal artery, or between the first and second branch of the pericallosal artery. In all patients, precontrast CT performed immediately after trauma depicted subarachnoid hemorrhage (SAH) in the anterior interhemispheric fissure (AIHF). Follow-up precontrast CT showed nodular high density around the anterior falx in three, recurrent SAH in the AIHF in two, and intracerebral hemorrhage (ICH) with intraventricular hemorrhage in two. In two patients with a nodular high-density lesion, nodular enhancement was demonstrated at postcontrast CT, and in one, follow-up MRI revealed a nodular signal void around the anterior falx; nodular enhancement was seen at postcontrast imaging, and MR angiogram depicted a saccular aneurysm. In one patient, MRI demonstrated infarction in the caudate nucleus and ACA territory. CONCLUSION: If, after head injury, an area of nodular high density is revealed by CT, or a signal void by MRI, or if SAH or ICH is present around the anterior falx, the possibility of TICA should be considered.

Background:
After the global epidemic of coronavirus disease 2019 (COVID-19), lifestyle changes to curb the spread of COVID-19 (e.g., wearing a mask, hand washing, and social distancing) have also affected the outbreak of other infectious diseases. However, few studies have been conducted on whether the incidence of gastrointestinal infections has changed over the past year with COVID-19. In this study, we examined how the incidence of gastrointestinal infections has changed since COVID-19 outbreak through open data.
Methods:
We summarized the data on the several viruses and bacteria that cause gastrointestinal infections from the open data of the Korea Disease Control and Prevention Agency for 3 years from March 2018 to February 2021 (from Spring 2018 to Winter 2020). Moreover, we confirmed three most common legal gastrointestinal infectious pathogens from March 2016.
Results:
From March 2020, when the COVID-19 epidemic was in full swing and social distancing and personal hygiene management were heavily emphasized, the incidence of infection from each virus was drastically decreased. The reduction rates compared to the averages of the last 2 years were as follows: total viruses 31.9%, norovirus 40.2%, group A rotavirus 31.8%, enteric adenovirus 13.4%, astrovirus 7.0%, and sapovirus 12.2%. Among bacterial pathogens, the infection rates of Campylobacter and Clostridium perfringens did not decrease but rather increased in some periods when compared to the average of the last two years. The incidence of nontyphoidal Salmonella, Staphylococcus aureus, or enteropathogenic Escherichia coli somewhat decreased but not significantly compared to the previous two years.
Conclusion
The incidence of infection from gastrointestinal viruses, which are mainly caused by the fecal-to-oral route and require direct contact among people, was significantly reduced, whereas the incidence of bacterial pathogens, which have food-mediated transmission as the main cause of infection, did not decrease significantly.

PURPOSE: We evaluated the prognostic significance of p53 and proliferating cell nuclear antigen(PCNA) in stage III gastric carcinoma to determine the correlation between the p53 and PCNA expression and various clinicopathological parameters. MATERIALS AND METHODS: The expression of p53 and PCNA were studied immunohistochemically in 64 cases of stage III gastric carcinomas with paraffin-embedded tissue specimens which were obtained surgically at the department of surgery, Presbyterian Medical Center from 1991 to 1992. Both expression were compared with known factors of prognosis. Survival rate and other clinicopathological parameters were analysed. RESULTS: Expression rates of p53 and high PCNA group were 40.6% and 26.6%, respectively. There was no significant correlation between the p53 and PCNA expression and various clinicopathological variables such as age, sex, stage, histology, tumor depth, number of metastatic node, tumor size, site and method of operation. To analyse survival, we evaluated overall survival according to the extent of p53 and PCNA expression. No significant correlations between the p53 and PCNA expression and overall survival were found. CONCLUSION: These results suggest that the p53 and PCNA expression seems to be hard to use as a prognostic indicator in stage III gastric carcinoma.

Journal of the Korean Fracture Society 2005;18(3):281-285
PURPOSE: To evaluate the necessity of deltoid ligament repair in lateral malleolar fracture associated with medial clear space widening. MATERIALS AND METHODS: The 82 cases of 82 patients received surgical treatment for lateral malleolar fracture with medial clear space widening in our hospital from Jan. 1996 to Feb. 2002. 73 male and 9 female patients were included respectively. Average follow-up period was 13.2 month (12~50). The methods of internal fixation of lateral malleolar fracture were 66 cases by cortical screw, 16 by plate and screws, and 9 by transfixing screw. RESULTS: Satisfactory reduction was obtained in 65 of 73 cases by only internal fixation of lateral malleolar fracture. Transfixing screw was needed in 8 cases. There was no need for repair of deltoid ligament. In clinical evaluation, no cases of limitation of movement in ankle was seen at final follow-up time. In radiologic evaluation, average medial clear space widening before operation was 5.89 mm (4.5~13 mm) and that of last follow-up time was 2.54 mm (1.5~3.5 mm). 95.2% was above good result. CONCLUSION: In treatment of unstable lateral malleolar fracture associated with medial clear space widening due to rupture of deltoid ligament, we obtained satisfactory result by accurate anatomical reduction or internal fixation. In these cases, there were no need for repair of deltoid ligament.

PURPOSE: To analyze the risk factors and the treatment results of the distal chevron osteotomy for the hallux valgus in young adult. MATERIALS AND METHODS: Eleven cases of hallux valgus in 9 patients who underwent the distal chevron osteotomy between February 2000 and January 2004 were included for the study. For the clinical evaluation, we used hallux-metatarsophalangeal interphalangeal scale of American Orthopaedic Foot and Ankle Society (AOFAS). For radiological evaluation, we measured hallux valgus angle (HVA) and intermetatarsal angle (IMA). RESULTS: Five patients had family history of hallux valgus. Symptoms were aggravated by military drill and sports activity. The average AOFAS scale was 62.5 preoperatively, and 88.4 at final follow-up. The HVA and IMA were 34.9 degrees, and 15.8 degrees preoperatively, 16.3 degrees and 8.2 degrees at postoperative 6 weeks, and 19.9 degrees and 9.8 degrees at final follow-up. CONCLUSION: The symptoms of hallux valgus in young adults were aggravated by military drill and sports activity. Distal chevron osteotomy was useful for the treatment of the moderate to severe hallux valgus in young patients.
