The risk of gastric cancer according to changes in smoking status among Korean men.

Objectives: Smoking is a risk factor for gastric cancer. Studies have shown that the risk of gastric cancer can vary by smoking status and smoking amount at a single point in time. However, few data have been reported about the effect of changes in smoking status over time on the risk of gastric cancer.

Change in smoking status and its relation to the risk of gastroduodenal ulcer in Korean men.

Background And Aim: Smoking is associated with the increased risk of gastroduodenal ulcer. However, although smoking status can vary over time, most of studies have analyzed this association with smoking status at a single point of time. We analyzed the risk of gastroduodenal ulcer according to change in smoking status for more than 5 years.

The association of pancreatic cancer incidence with smoking status and smoking amount in Korean men.

Objectives: Our study examined the dose-response relationship between smoking amounts (pack-years) and the risk of developing pancreatic cancer in Korean men.

Methods: Of 125,743 participants who underwent medical health checkups in 2009, 121,408 were included in the final analysis and observed for the development of pancreatic cancer. We evaluated the associations between smoking amounts and incident pancreatic cancer in 4 groups classified by pack-year amounts.

Respiration monitoring in PACU using ventilation and gas exchange parameters.

The importance of perioperative respiration monitoring is highlighted by high incidences of postoperative respiratory complications unrelated to the original disease. The objectives of this pilot study were to (1) simultaneously acquire respiration rate (RR), tidal volume (TV), minute ventilation (MV), SpO and PETCO from patients in post-anesthesia care unit (PACU) and (2) identify a practical continuous respiration monitoring method by analyzing the acquired data in terms of their ability and reliability in assessing a patient's respiratory status. Thirteen non-intubated patients completed this observational study.

Methods: A prospective randomized controlled trial conducted at Kyung Hee University hospital, South Korea, from August 2016 to September 2017. Patients were randomized to receive either 10 mg dexamethasone before induction of anesthesia (control group C), followed by intravenous administration of patient-controlled analgesia (IV-PCA) or 2 ml normal saline before induction of anesthesia and 0.

Hyperchloremic metabolic acidosis during bipolar transurethral resection of the prostate: a report of two cases.

Compared with monopolar transurethral resection of the prostate (TURP), which requires electrolyte-free irrigation fluid, normal saline can be used as the irrigation solution in bipolar and laser TURP. The risk of TURP syndrome and severe electrolyte disturbance is minimized when normal saline is used as the irrigation fluid. However, the use of isotonic saline also causes acid-base imbalance and electrolyte disturbance.

Correlation between the Perfusion Index and Intraoperative Hypothermia: A Prospective Observational Pilot Study.

We examined the association between the baseline perfusion index (PI) and changes in intraoperative body temperature during general anesthesia. The PI reflects the peripheral perfusion state. The PI may be associated with changes in body temperature during general anesthesia because the degree of redistribution of body heat from the central to the peripheral compartment varies depending on the peripheral perfusion state.

General anesthesia for old Werner syndrome patient: a case report.

Werner syndrome (WS) is a rare autosomal recessive, premature aging disorder whose clinical manifestations include short stature, bilateral cataracts, diabetes mellitus, hypertension, and atherosclerosis. WS first manifests during adolescence and patients usually die at 40-50 years of age. Only symptomatic treatment options available according to clinical manifestations.

Early Skin Test after Anaphylaxis during Induction of Anesthesia: A Case Report.

Background: It is recommended that a skin test be performed 4-6 weeks after anaphylaxis. However, there is little evidence about the timing of the skin test when there is a need to identify the cause within 4-6 weeks.

Case Report: A 57-year-old woman was scheduled to undergo surgery via a sphenoidal approach to remove a pituitary macroadenoma.

Prognostic impact of preoperative serum alkaline phosphatase level on a composite of morbidity and mortality after thoracic endovascular aortic repair: A retrospective study.

Background: Serum alkaline phosphatase (ALP) is related to vascular calcification and is known to have a prognostic impact in various cohorts. However, evidence in patients undergoing thoracic endovascular aortic repair (TEVAR) is lacking. Thus, we hypothesized that preoperative serum ALP level could be used for predicting adverse events after TEVAR.

Pneumothorax after minimally invasive plate osteosynthesis for midshaft clavicle fracture: A case report.

Rationale: Isolated fracture of clavicle is usually treated with nonoperative conservative treatment. However, surgical treatment, customized for individual patient's need, is increasingly done. With regard to the surgery of the clavicle fracture, pneumothorax is a possible, but rare complication.

Serum Alkaline Phosphatase as a Predictor of Cardiac and Cerebrovascular Complications after Lumbar Spinal Fusion Surgery in Elderly: A Retrospective Study.

We retrospectively enrolled 1395 patients aged > 65 years undergoing posterior lumbar spinal fusion surgery and classified them into tertiles based on serum Alkaline Phosphatase (ALP) levels (<63, 63-79, >79 IU/L). The primary outcome was the incidence of 30-day major adverse cardiac and cerebrovascular events (MACCE; composite endpoint defined as the occurrence of ≥1 of the following events: new-onset myocardial infarction, stroke, or cardiovascular mortality). The incidence of the composite endpoint was the highest in the third serum ALP tertile (0.

Effect of remifentanil and midazolam on ED95 of propofol for loss of consciousness in elderly patients: A randomized, clinical trial.

Background: Older people are more vulnerable to hemodynamic instability caused by propofol due to their decreased initial distribution volume and increased sensitivity to propofol. Midazolam or remifentanil can often be coadministered because of their synergistic or additive effects with propofol as well as amnesic properties and the blockade of sympathetic stimulation. However, no study has confirmed the appropriate dose of propofol for loss of consciousness in aged patients when administered with other drugs, including opioids or benzodiazepines.

Effects of positive end-expiratory pressure on intraocular pressure and optic nerve sheath diameter in robot-assisted laparoscopic radical prostatectomy: A randomized, clinical trial.

Background: There has been no study of the effect of post end-expiratory pressure (PEEP) on intraocular or intracranial pressure during pneumoperitoneum with steep Trendelenburg positioning. We investigated the effects of 5 cmH2O of PEEP on intraocular pressure and optic nerve sheath diameter as a surrogate for intracranial pressure in robot-assisted laparoscopic radical prostatectomy.

Methods: Fifty patients scheduled for robot-assisted laparoscopic radical prostatectomy were divided into a zero-PEEP (ZEEP) group and a 5 cmH2O of PEEP (PEEP) group.

Transthoracic radiofrequency ablation for hepatic tumor located beneath the diaphragm under one-lung ventilation: A case report.

Rationale: Radiofrequency ablation (RFA) has become the reliable, effective, and less invasive treatment for small primary or metastatic hepatic tumors. Hepatic tumors that located immediately beneath the diaphragm are difficult to treat with percutaneous RFA due to poor visualization by percutaneous ultrasonography and the close location of the heart or lung. A transthoracic approach has been proposed to be an alternative for hepatic tumors located beneath the diaphragm that are difficult to access by conventional percutaneous or laparoscopic approaches.
