Background:
Nonobstetric surgery is sometimes required during pregnancy, and neck abscess or facial bone fracture surgery cannot be postponed in pregnant women. However, dental surgery can be stressful and can cause inflammation, and the inflammatory response is a well-known major cause of preterm labor. Propofol is an intravenous anesthetic commonly used for general anesthesia and sedation. Studies investigating the effect of propofol on human amnion are rare. The current study investigated the effects of propofol on lipopolysaccharide (LPS)-induced inflammatory responses in human amnion-derived WISH cells.
Methods:
WISH cells were exposed to LPS for 24 h and co-treated with various concentrations of propofol (0.01–1 μg/ml). Cell viability was measured using the MTT assay. Nitric oxide (NO) production was analyzed using a microassay based on the Griess reaction. The protein expression of cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE 2), p38, and phospho-p38 was analyzed using western blotting.
Results:
Propofol did not affect the viability and NO production of WISH cells. Co-treatment with LPS and propofol reduced COX-2 and PGE 2 protein expression and inhibited p38 phosphorylation in WISH cells.
Conclusion
Propofol does not affect the viability of WISH cells and inhibits LPS-induced expression of inflammatory factors. The inhibitory effect of propofol on inflammatory factor expression is likely mediated by the inhibition of p38 activation.

BACKGROUND: Empyema is the collection of purulent exudate within the pleural space. Overall, 36%–65% of patients with empyema cannot be treated by medical therapy alone and require surgery. Multiloculated empyema is particularly difficult to treat with percutaneous drainage. Therefore, we describe our experiences with early aggressive surgical treatment for rapid progressive multiloculated empyema. METHODS: From January 2001 to October 2015, we retrospectively reviewed 149 patients diagnosed with empyema who received surgery. The patients were divided into 2 groups according to whether they underwent emergency surgery or not. We then compared surgical outcomes between these groups. RESULTS: The patients in group A (emergency surgery, n=102) showed a more severe infectious state, but a lower complication rate and shorter length of hospital stay. The incidence of lung abscess was higher in group A, and abscesses were associated with diabetes and severe alcoholism. CONCLUSION: Early aggressive surgical treatment resulted in good surgical outcomes for patients with rapid progressive multiloculated empyema. Furthermore, we suspect that the most likely causes of multiloculated empyema are lung abscesses found in patients with diabetes mellitus as well as severe alcoholism.

A 47-year-old woman was referred for surgical treatment of osteomyelitis of the mandible. She had already undergone three previous surgeries. Pre-anesthetic airway evaluation predicted a difficult airway, due to the thin, retro-positioned mandible, tongue, and atrophic changes in the lips and soft tissue. We inserted packing gauzes in the buccal mucosa for easier mask fitting and ventilation. During direct laryngoscopic intubation with a nasotracheal tube (NTT), fracture of a thin mandible can easily occur. Therefore, we used a fiberoptic bronchoscope to insert the NTT. After surgery, we performed a tongue-tie to protect against airway obstruction caused by the backward movement of the tongue during recovery. The patient recovered without any complications. We determined the status of the patient precisely and consequently performed thorough preparations for the surgery, allowing the patient to be anesthetized safely and recover after surgery. Careful assessment of the patient and airway prior to surgery is necessary.

Patients with cleft lip and palate (CLP) must undergo corrective surgeries during infancy and early childhood. Many patients with CLP undergo orthognathic surgery during their childhood for correction of skeletal asymmetries or pharyngoplasty with a pharyngeal flap to improve the quality of speech and velopharyngeal function. During orthognathic surgeries, nasotracheal intubation is performed under general anesthesia. In our case report, the patient had undergone palatoplasty and pharygoplasty previously. During the orthognathic surgery, a flexible fiberoptic bronchoscope-guided nasotracheal tube was inserted through the pharyngeal flap ostium; however, active bleeding occurred in the nasopharynx. Bleeding occurred because the flap was torn. After achieving hemostasis, the surgery was completed successfully. Thus, if a patient may show the potential for velopharyngeal port obstruction, nasotracheal intubation should be performed with utmost care.

Solitary fibrous tumor of the pleura (SFTP) is a rare primary intrathoracic tumor that arises from mesenchymal tissue underlying the mesothelial layer of the pleura. It usually has an indolent clinical course. The hypoglycemia that accompanies SFTP was first described by Doege and Potter independently in 1930, hence the eponym Doege-Potter syndrome (DPS). The incidence of DPS is reported to be ~4%. In this report, we present a typical case of DPS that was cured through complete surgical resection.

A 51-year-old woman visited our hospital with massive hemoptysis. She had suffered from recurrent hemoptysis for five years and had undergone bronchial artery embolization many times. The patient had a history of pulmonary tuberculosis and bronchiectasis. Chest radiography showed consolidation around the nodule in the lateral basal segment of the right lower lobe. We successfully performed a right lower lobectomy. The histological study of the resected specimen showed a vegetable foreign body and clumps of Actinomyces, indicating actinomycosis, which was suggested to be the cause of the hemoptysis. This was a very rare case of hemoptysis caused by a vegetable foreign body and actinomycosis.

BACKGROUND: Numerous statistical models have been developed to accurately predict outcomes in multiple trauma patients. However, such trauma scoring systems reflect the patient's physiological condition, which can only be determined to a limited extent, and are difficult to use when performing a rapid initial assessment. We studied the predictive ability of the systemic inflammatory response syndrome (SIRS) score compared to other scoring systems. METHODS: We retrospectively reviewed 229 patients with multiple trauma combined with chest injury from January 2006 to June 2011. A SIRS score was calculated for patients based on their presentation to the emergency room. The patients were divided into two groups: those with an SIRS score of two points or above and those with an SIRS score of one or zero. Then, the outcomes between the two groups were compared. Furthermore, the ability of the SIRS score and other injury severity scoring systems to predict mortality was compared. RESULTS: Hospital death occurred in 12 patients (5.2%). There were no significant differences in the general characteristics of patients, but the trauma severity scores were significantly different between the two groups. The SIRS scores, number of complications, and mortality rate were significantly higher in those with a SIRS score of two or above (p<0.001). In the multivariant analysis, the SIRS score was the only independent factor related to mortality. CONCLUSION: The SIRS score is easily calculated on admission and may accurately predict mortality in patients with multiple traumas.

BACKGROUND: Gabapentin is a safe and well-tolerated anticonvulsant with a wide therapeutic index, and it is used for neuropathic pain. The aim of this study was to compare previous dosing methods with the administration of four different doses of gabapentin while maintaining the same maximum daily dose for the safe administration of high doses of the medication. METHODS: The subjects were outpatients with various neuropathic pain syndromes, with at least two of the following symptoms: allodynia, burning pain, shooting pain, or hyperalgesia. The TID group received equal doses of gabapentin 3 times per day, while the QID group received 4 different doses of gabapentin per day. The pain score, frequency of breakthrough pain (BTP), severity and the duration of pain, sleep disturbance due to nocturnal pain, and adverse effects were recorded each day. RESULTS: The average daily pain score and sleep disturbance were significantly reduced in the QID group between days 3 and 10 of the experiment. The adverse effects of the medication were also reduced in the QID group. However, the frequency of BTP and severity and duration of pain were not significantly different between two groups. CONCLUSIONS: Administration of 4 different doses of gabapentin during the initial titration in outpatients with neuropathic pain resulted in a significant reduction in awakening from breakthrough pain and a reduction in the adverse effects of the medication.

PURPOSE: The purpose of this study was to determine the efficacy and safety of treatment using gemcitabine and capecitabine for patients with advanced pancreatic cancer. MATERIALS AND METHODS: Patients with advanced unresectable pancreatic adenocarcinoma were enrolled in the study. Inclusion criteria included no prior systemic chemotherapy or radiation therapy, at least one radiographically documented and measurable tumor lesion, and adequate patient organ functions. The patients received 1,000 mg/m2 gemcitabine intravenously on days 1, 8 and 15, and 830 mg/m2 of oral capecitabine twice a day on days 1-21 of a 28-day cycle. RESULTS: Fifty patients with a median age of 53 years (range, 39 to 76 years) were enrolled in the study. The median follow-up was 10.0 months. The objective response rate of the 50 patients was 48.0% (95% CI, 22.5 to 57.1%). The median time to progression and overall survival were 6.5 months (95% CI, 2.3 to 8.7 months) and 10.0 months (95% CI, 5.7 to 16.7 months), respectively. Grade 3-4 toxicities associated with chemotherapy included neutropenia (22%), anemia (8%), thrombocytopenia (6%), and hand-foot syndrome (10%). CONCLUSION: Combination chemotherapy using gemcitabine and capecitabine was well tolerated and demonstrated promising efficacy in the treatment of advanced pancreatic cancer.

OBJECTIVETo summarize and critically evaluate the evidence for and against the effectiveness of Eastern-Western integrative medicine (EWIM) for health care compared to Eastern medicine (EM) or Western medicine (WM) alone.
METHODSSystematic searches were conducted on five Korean medical databases. Manual searches were also conducted through nine major Korean medical journals. Prospective randomized clinical trials (RCTs) were included if EWIM was tested for any type of conditions compared to EM or WM.
RESULTSThere were one hundred forty-one possibly relevant studies were identified, and seven RCTs were included. The risk of bias was high in most studies. The EWIM methods were compared with EM or WM in patients with pain conditions in four studies. These studies showed favorable effects of EWIM on pain reduction in patients with shoulder pain and chronic headache compared with EM, while the other RCTs failed to do so in traffic injury patients. Two studies tested EWIM in patients with Bell's palsy compared with EM and found acute functional improvement. An RCT comparing EWIM with WM in patients with acne showed a significant difference.
CONCLUSIONThe results of our systematic review suggest that there is limited evidence for the superiority of EWIM over EM or WM in the treatment of pain and acute symptom improvement in patients with Bell's palsy. The evidence from our analysis was limited from the low number of RCTs included and the high risk of bias. Future RCTs appear to be warranted.
