PURPOSE: Laparoscopic totally extraperitoneal (TEP) hernia repair is known to be relatively difficult in cases with a history of lower abdominal surgery. We assess the feasibility of laparoscopic TEP hernia repair in those patients. METHODS: Thirty five patients with a previous history of radical prostatectomy or lower abdominal surgery who underwent laparoscopic TEP hernia repair for inguinal hernia were reviewed retrospectively. All operations were performed by a single experienced surgeon. RESULTS: Thirty three out of the 35 patients (94%) were men. Laparoscopic TEP hernia repair was performed successfully in 30 out of 35 cases. Twenty five cases (71%) were right inguinal hernia, 6 cases (17%) were left hernias, and 4 cases (11%) had an inguinal hernia on both sides. Five cases were converted to transabdominal preperitoneal (TAPP) (n=3) or open methods (n=2). Mean operation time was 111 minutes. The patient group with previous radical prostatectomy was the largest (n=22, 63%) and required a longer operation time (124 minutes). Blood loss was less than 50 cc in all cases. Average hospital stay was 1.2 days after surgery. Voiding difficulties requiring catheterization were observed in 13 cases (37%). CONCLUSION: Laparoscopic TEP hernia repair for a patient with previous history of radical prostatectomy or lower abdominal surgery except for appendectomy can be safely performed by an experienced surgeon, but is not recommended as a standard choice because of a longer operation time and higher conversion rate.

Spontaneous intracranial hypotension, a syndrome of low CSF pressure, occurs without preceding events such as lumbar puncture, back trauma, operative procedure or medical illness. The most characteristic symptom is a headache that may be severe when the patient is upright and relieved when the patient is recumbent. Associated symptoms include neck stiffness, nausea and vomiting, tinnitus, vertigo and subdural effusion or hematoma. This syndrome usually resolves spontaneously or with strict bed rest. When the headache persists or is incapacitating, more aggressive treatment may be necessary. Autologous epidural blood patch is highly effective in the management of spontaneous intracranial hypotension. We report a case of spontaneous intracranial hypotension successfully treated with epidural blood patch.

Protein C exerts anticoagulatory effects by inactivating factor V and VII and stimulating fibrinolysis. Hereditary protein C-deficient individuals have an increased risk of venous thrombosis and thromboembolism at young age. To our knowledge, the deep cerebral venous thrombosis associated with protein C deficiency has not been reported in Korea. A 34-year-old man was admitted to our hospital because of sudden onset of headache with nausea, vomiting and ocular pain. He had suffered from recurrent deep vein thrombosis of the right lower extremity for one year. Brain MRI showed thrombosis of the straight and confluent sinuses and venous infarction of the right thalamus. The result of cerebral angiography corresponded to MRI findings. Protein C antigen concentration was decreased to 65% and its functional activity was 37%. Other coagulation test and routine blood examination was normal. The protein C level of his mother was low in both antigen and activity, but protein C levels of three siblings were normal in functional activity. We speculate that the etiology of the deep cerebral venous thrombosis in this patient is associated with protein C deficiency and suggest it is valuable to measure protein C level in patients with cerebral venous thrombosis.

Idiopathic intracranial hypertension, a syndrome of obscure origin, occurs particularly in fat adolescent girls and young women. The usual symptoms are headache, blurred vision, a vague dizziness, horizontal diplopia and transient visual obscurations etc., and ophthalmoscopic examination reveals papillederma, due to increased ICP. Visual field testing usually shows slight peripheral constrictions with enlargement of the blind sports. CSF pressure is elevated in the range of 250 to 450 mm of water. Radiological or the other laboratory tests show no specific abnormalities. Treatment for idiopathic intracranial hypertension is focused on early detection and prevention of vision loss, the only permanent morbidity. Many different modes of medical treatment, including weight reduction, repeated lumber puncture, corticosteroids, diuretics, glycerol or carbonic anhydrase inhibitors, have successfully been tried up to 90% of the patients. In the remaining patients, particularly in those with measurable impairment of vision that does not respond to conventinal medical therapies, surgical procedure should be considered. We report a case of idiopathic intracranial hypertension successfully treated with optic nerve sheath fenestration.

Complete or partial agenesis of dorsal pancreas has been reported in a small number of pediatric and adult patients. A case of partial agenesis of dorsal pancreas was reported. This case was not associated with diabetes mellitus and pancreatic exocrine dysfunction, or abdominal pain. A 37-year-old man with chronic hepatitis B visited to our hospital due to further examination for chronic hepatitis B. Abdominal ultrasonography showed enlarged pancreatic head. Diagnosis was made by endoscopic retrograde cholangiopancreatography and computed tomography. Explor-laparotomy was not done.

PURPOSE: Mistletoe extract was widely used for cancer treatment as complementary or alternative therapy in European area from early twenty century. It is currently used as alternative anti-cancer remedy by piecemeal in domestic medical group, however, the anti-cancer mechanism of mistletoe extract was not known precisely until now. In this study the effect of mistletoe extract on gastric cancer was studied vis cell line experiments. MATERIALS AND METHODS: The SNU719 gastric cancer cell line was used, and ABNOBAviscum-Q and ABNOBAviscum-F were treated to cells as mistletoe extract, or 5-FU and cisplatin were used with mistletoe extract. The cell viability and cell death rate were estimated by CCK-8 assay kit and lactate dehydrogenase (LDH) assay kit in each. Caspase 3 assay kit was used to measure caspase 3 activity. The protein expression amounts of Bcl2, p53, and PTEN were estimated through Western blot analysis. RESULTS: The co-treatments of mistletoe extract Q/F and 5-FU/cisplatin decreased lesser cell viability than only mistletoe treat. Caspase 3 activity was increased 4~6 times in co-treatment of mistletoe extracts and 5-FU than control. Bcl2 protein expression was reduced by mistletoe extracts or anti-cancer drugs, further more, the co-treatment of mistletoe extracts and 5-FU/cisplatin diminished more the expression than only mistletoe treatment. Mistletoe extracts did not affect the protein expressions of p53 and PTEN. CONCLUSION: It was concluded that the anti-cancer mechanism of mistletoe extracts was made by caspase 3 activation and lowered Bcl2 expression, and this apoptosis inducing mechanism was independent to p53.

OBJECTIVE: The aim of this study was to identify the expression of nitric oxide synthases (NOS) in the mandibular condyle during mandible advancement by functional appliance and to correlate it with the histologic changes and bone remodeling. METHODS: Twenty-four female, 35-day-old Sprague-Dawley rats were randomly divided into 3 experimental groups. In all experimental groups, the mandibles of the rats were kept in a continuous forward position with a fixed bite jumping appliance. The rats were sacrificed on the 3rd, 14th, and 30th days of experiment. More than 2 rats in each group were used for staining. RESULTS: There were no remarkable histologic changes and NOS expression differences in the control group. The most prominent histologic changes occurred in the 14th day experimental group. NOS decreased in the 30th day experimental group. There was increased expression of NOS2 and NOS3 in all experimental groups, comparative to the control group. In all the experimental groups and control group, the expression of NOS2 was greater than that of NOS3. CONCLUSIONS: It is postulated that NOS2 and NOS3 in the mandibular condyle might play an important role in bone remodelling of the mandibular condyle.

OBJECTIVE: The purpose of this study was to determine the effects of carbonated water on etched or sealed enamel according to the carbonation level and the presence of calcium ions. METHODS: Carbonated water with different carbonation levels was manufactured by a soda carbonator. Seventy-five premolar teeth were randomly divided into a control group and 4 experimental groups in accordance with the carbonation level and the presence of calcium ions in the test solutions. After specimen preparation of the Unexposed, Etched, and Sealed enamel subgroups, all the specimens were submerged in each test solution for 15 minutes three times a day during 7 days. Microhardness tests on the Unexposed and Etched enamel subgroups were performed with 10 specimens from each group. Scanning electron microscopy (SEM) tests on the Unexposed, Etched, and Sealed enamel subgroups were performed with 5 specimens from each group. Microhardness changes in different groups were statistically compared using paired t-tests, the Wilcoxon signed rank test, and the Kruskal-Wallis test. RESULTS: The microhardness changes were significantly different between the groups (p = 0.000). The microhardness changes in all experimental groups except Group 3 (low-level carbonated water with calcium ions) were significantly greater than those in the Control group. SEM showed that etched areas of the specimen were affected by carbonated water and the magnitude of destruction varied between groups. Adhesive material was partially removed in groups exposed to carbonated water. CONCLUSIONS Carbonated water has negative effects on etched or sealed enamel, resulting in decreased microhardness and removal of the adhesive material.

Background: This study aimed to determine factors affecting serum levels of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies 2 months after coronavirus disease 2019 (COVID-19) vaccination in young and middle aged healthy adults. Materials and Methods: Healthcare workers who have no history of SARS-CoV-2 infection, were enrolled at 2 months after second shot of BNT162b2 mRNA COVID-19 vaccine. Antibody immunoglobulin G against the spike protein subunit of SARS-CoV-2 was semi-quantitatively measured using 4 commercial enzyme-linked immunosorbent assay kits. Factors affecting anti-SARS-CoV-2 antibodies levels were investigated. Results: Fifty-one persons (22 - 54 years, male sex; 19.6%) were enrolled and all participants acquired anti-SARS-CoV-2 antibodies in four diagnostic kits. Anti-SARS-CoV-2 antibodies were strongly correlated between diagnostic kits; SG Medical and Genscript (r = 0.942), SG Medical and HB Healthcare (r = 0.903), and HB Healthcare and Genscript (r = 0.868). We investigated factors affecting antibody level using SG medical kit. The median inhibition was 93.1%, and 84.0% of participants showed >90.0% inhibition. Systemic adverse event severity had no association with the anti-SARS-CoV-2 antibodies level. Antibody level was inversely correlated with weight (-0.312, P = 0.027), body mass index (BMI) (r = -0.303, i>P = 0.032), and body surface area (r = -0.285, i>P = 0.044). In multivariate analysis, the upper 50% of antiSARS-CoV-2 antibodies (≥93.1%) was inversely associated with weight (odds ratio [OR]: 0.19; 95% confidence interval [CI]: 0.04 - 0.83 in weight ≥55kg) and BMI (OR: 0.12; 95% CI: 0.03 - 0.61 in BMI ≥22 kg/m2 ). Conclusion Anti-SARS-CoV-2 antibody was inversely correlated with weight and BMI, which may be used as a marker to predict immune response of BNT162b2 mRNA vaccination in young and middle aged adults.
