  • Septic pulmonary embolism is a rare disease entity that consists of pulmonary infection and embolism predominantly arising from endocarditis and thrombophlebitis. We report a rare case of candidal septic pulmonary embolism secondary to odontogenic infection in a previously healthy and immunocompetent man, who had a submandibular abscess with dyspnea and fever. The patient was not responsive to prolonged broad spectrum antibiotics and surgical drainage, however, antifungal therapy was successful after Candida albicans was confirmed by his blood culture. Since proper identification and the resolution of the septic origin is as important as the diagnosis of septic pulmonary embolism, in a patient with odontogenic infection, who shows definite respiratory complications despite antimicrobial therapy with surgical drainage, various culture examinations should be adopted.

  • The cleft lip and palate charity operation team visited Binh Duong General Hospital in Vietnam from 17th Dec to 25th Dec 2004. Total 25 cleft lip and palate patients (male : female = 15:10) were undergone the operation. The mean age of the patients was 13.6 year. The types of surgical operation were primary cheilorrhaphy (8 cases), primary palatorrhaphy(10 cases), pharyngoplasty(2 cases), scar revision(3 cases), alveolorrhaphy(2 cases). There were no intraoperative and immediate postoperative complications. The year 2004 was the 10th charity operation in the same area so it is meaningful to review the start of this charity mission and the course, and the future of our activity.

  • Deep sedation is considered for the dental treatment of pediatric or disabled patients who have severe anxiety or involuntary movement. Deep sedation using sevoflurane inhalation in emergency dental practice, therefore, is also preferred for fast induction and recovery. This survey consists of 121 people with pediatric or disabled patients who underwent dental treatment under deep sedation using sevoflurane inhalation from January 2013 to October 2013. Patients who were scheduled for deep sedation were classified into a non-emergency sevoflurane sedation group, whereas patients who underwent emergency sedation due to trauma and patients with disabled characteristics itself were classified into an emergency sevoflurane sedation group. Of 121 patients studied, 95 patients received dental care under non-emergency sedation, 26 patients received dental care under emergency sevoflurane sedation. The two groups were analyzed according to: gender; age; primary reason for sedation; duration of sedation; treatment time; induction methods; treatment information; and departments. Non-emergency sevoflurane sedation in pediatric or disabled patients was safe and effective for controlling the behavior. Emergency sevoflurane sedation was a useful method for younger pediatric patients with traumatic injury who need simple, short time emergency treatment. Deep sedation using sevoflurane inhalation not only will reduce the use of general anesthesia gradually but also will be a useful method to emergency treatment for pediatric or disabled patients.

  • Background: Third molar extraction is associated with considerable pain and discomfort, which is mostly managed with oral analgesic medication. We assessed the analgesic effect of benzydamine hydrochloride, a topical analgesic oral rinse, for controlling postoperative pain following third molar extraction. Methods: A randomized controlled trial was conducted in 40 patients divided into two groups, for extraction of fully erupted third molar. Groups A received benzydamine hydrochloride mouthwash and group B received normal saline gargle with oral ibuprofen and paracetamol. Oral ibuprofen and paracetamol was the rescue analgesic drug in group A. Patients were evaluated on the $3^{rd}$ and $7^{th}$ post-operative days (POD) for pain using the visual analogue score (VAS), trismus, total number of analgesics consumed, and satisfaction level of patients. Results: The VAS in groups A and B on POD3 and POD7 was $4.55{\pm}2.54$ and $3.95{\pm}1.8$, and $1.2{\pm}1.64$ and $0.95{\pm}1.14$, respectively and was statistically insignificant. The number of analgesics consumed in groups A and B on POD3 ($5.25{\pm}2.22$ and $6.05{\pm}2.43$) was not statistically different from that consumed on POD7 ($9.15{\pm}5.93$ and $10.65{\pm}6.46$). The p values for trismus on POD3 and POD7 were 0.609 and 0.490, respectively and those for patient satisfaction level on POD3 and POD7 were 0.283 and 0.217, respectively. Conclusions: Benzydamine hydrochloride oral rinses do not significantly reduce intake of oral analgesics and are inadequate for pain relief following mandibular third molar extraction.

  • Pulmonary arterial hypertension (PAH) is a common complication of Congenital heart defects (CHD) with left-to-right shunts, and PAH with increased pulmonary vascular resistance (PVR) is associated with considerable morbidity and mortality. General anesthesia (GA) can be life-threatening in patients with PAH, because the positive pressure ventilation during GA increases pulmonary arterial pressure and decreases pulmonary blood flow. This may also lead to hypoxia. Therefore, spontaneous ventilation may be safer than positive pressure ventilation in patients with PAH. A five-year-old male child, weighing 11 kg, with medical history showing a total correction of Tetralogy of Fallot (TOF) in 2009 and ongoing treatment with hypertension (HTN) medicine since 2007, visited the Dankook University Dental Hospital. He had multiple dental caries, and the treatment was completed under sevoflurane insufflation sedation via nasal cannula. The patient remained sedated throughout the operation while maintaining normal vital signs and spontaneous respiration. In conclusion, sevoflurane insufflation sedation may be a safer alternative to GA for the dental treatment of patients with PAH.

  • Background: Incisional site of surgical operation become transient ischemic state and then occur reoxygenation due to vasodilatation by inflammatory reaction, the productive reactive oxygen species (ROS) give rise to many physiologic results. Apoptosis have major role on elimination of inflammatory cell and formation of granulation tissue in normal wound healing process. Remifentanil can prevent the inflammatory response and can suppress inducible nitric oxide synthase expression in a septic mouse model. After cardiopulmonary bypass for coronary artery surgery, remifentanil can also inhibit the release of biomarkers of myocardial damage. Here we investigated whether remifentanil pretreatment has cellular protective effect against hypoxia-reoxygenation in HaCaT human keratinocytes, if so, the role of apoptosis and autophagy on this phenomenon. Methods: The HaCaT human keratinocytes were exposed to various concentrations of remifentanil (0.01, 0.05, 0.1, 0.5 and 1 ng/ml) for 2 h before hypoxia (RPC/HR group). These cells were cultured under 1% oxygen tension for 24h at $37^{\circ}C$. After hypoxia, to simulate reoxygenation and recovery, the cells were reoxygenated for 12 h at $37^{\circ}C$. 3-MA/RPC/HR group was treated 3-methyladenine (3-MA), autophagy inhibitor for 1h before remifentanil treatment. Cell viability was measured using a quantitative colorimetric assay with thiazolyl blue tetrazoliumbromide (MTT, amresco), showing the mitochondrial activity of living cells. To investigate whether the occurrence of autophagy and apoptosis, we used fluorescence microscopy and Western blot analysis. Results: The viability against hypoxia-reoxygenation injury in remifentanil preconditioning keratinocytes were increased, and these cells were showed stimulated expression of autophagy 3-MA suppressed the induction of autophagy effectively and the protective effects on apoptosis. Atg5, Beclin-1, LC3-II and p62 were elevated in RPC/HR group. But they were decreased when autophagy was suppressed by 3-MA. Conclusions: Remifentanil preconditioning showed the protective effect in human keratinocytes, and we concluded that autophagy may take the major role in the recovery of wound from hypoxia-reoxygenation injury. We suggest that further research is needed about the cell protective effects of autophagy.

  • Background: The purpose of this study was to compare the clinical safety and effect with and without additional submucosal midazolam to oral chloral hydrate and hydroxyzine when used for pediatric conscious sedation in a clinical dental environment. Methods: Thirty one cases of pediatric conscious sedations were performed in this study. Selection criteria included good health (ASA I), under 6 years old, 20 kg of body weight, uncooperative behavior and the need for sedation to receive dental treatment including anesthesia and restorative or surgical procedure for at least two teeth. In each visit, patients were randomly assigned into one of two groups; CH group: chloral hydrate (60 mg/kg), hydroxyzine (1 mg/kg), CH-M group: chloral hydrate (60 mg/kg). hydroxyzine (1 mg/kg) and submucoal midazolam (0.1 mg/kg). 50% nitrous oxide-oxygen was maintained during the sedation period Sedations were monitored using a pulse oximeter for estimating pulse rate (PR) and percutaneous oxygen saturation ($SpO_2$). Behavior response rated using Houpt's scale and need of restraint was assessed every 2 minutes through 30 minutes of operative procedure reviewing the videotape recording. Evaluation of overall behavior success was performed using modified overall behavior rate of Houpt's scale. Data was analyzed using t-test. Results: PR and $SpO_2$ for both groups remained within the normal values. The mean scores for sleep and movement of CH-M group were higher than those of CH group (P < 0.05). There were no significant difference in mean score for crying between two groups. The mean scores of overall behavior of CH-M group was higher than those of CH group (P < 0.01). Reinstraint of CH-M group was less required than that of CH group (P < 0.05). Conclusions: Oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) combined with submucosal injection of midazolam was safer and showed more improved sedation effect than oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) without midazolam for sedation of pediatric dental patients.

  • Background: Gabapentin is a novel anti-epileptic drug, which is used in clinical practice to treat epilepsy. This drug is also used as an analgesic in pain patients. The antinociceptive effect of this drug was assessed using the formalin test in the rat. Methods: In order to investigate the effects of gabapentin on the trigeminal nerve territory, we injected 0.5% formalin into the upper lip. Adult, male, Sprague-Dawley rats received a $50{\mu}l$ subcutaneous injection of 5% formalin into one vibrissal pad and the consequent, facial grooming behavior was monitored. Consistent with previous investigations using tile formalin model, animals exhibited biphasic nocifensive grooming (phase 1, 0-12 min; phase 2, 12-60 min). Results: The intraperitoneal administration gabapentin 5 minutes prior to the formalin injection led to a significant, dose-dependent reduction in grooming time during phase 2. In high doses, gabapentin also reduced the time of grooming during phase 1. Conclusions: The Intraperitoneal injection of gabapentin has an analgesic effect in the facial formalin rat model and this analgesic effect increases dose-dependently.

  • Background: Identifying early markers of septic complications can aid in the diagnosis and therapeutic management of hospitalized patients. In this study, the utility of procalcitonin (PCT) vs. C-reactive protein (CRP) as early markers of sepsis was compared. Methods: A series of 2,697 consecutive blood samples was collected from hospitalized patients and serum PCT and CRP levels were measured. Patients were categorized by PCT level as follows: < 0.05 ng/ml, 0.05-0.49 ng/ml, 0.5-1.99 ng/ml, 2-9.99 ng/ml, and > 10 ng/ml. Diagnostic utility was analyzed by receiver operating characteristic (ROC) curves. Results: Mean CRP levels varied among the five PCT categories at $0.31{\pm}2.87$, $5.65{\pm}6.26$, $13.78{\pm}8.01$, $12.15{\pm}10.16$, and $17.77{\pm}10.59$, respectively (P < 0.05). PCT and CRP differed between positive and negative blood culture groups (PCT: 15.9 vs. 4.78 mg/dl;CRP: 11.5 ng/ml vs. 9.57 ng/ml;P < 0.05). The areas under the ROC curves (PCT, 95% confidence interval [CI]: 0.743, range: 0.698-0.789 at a threshold of 0.5 ng/ml; CRP, 95% CI: 0.540, range: 0.478-0.602 at a threshold of 8 mg/l) differed for PCT and CRP (P < 0.05). Conclusions: Therefore, PCT is a reliable marker for sepsis diagnosis and is more relevant than CRP in patients with a positive blood culture. These findings can be useful for the treatment of critically ill sepsis patients.

  • Heat shock proteins (HSPs) are specifically induced by various forms of stress. Hsp70.1, a member of the hsp70 family is known to play an important role in cytoprotection from stressful insults. However, the functional role of Hsp70 in motor function after spinal cord injury (SCI) is still unclear. To study the role of hsp70.1 in motor recovery following SCI, we assessed locomotor function in hsp70.1 knockout (KO) mice and their wild-type (WT) mice via the Basso, Beattie and Bresnahan (BBB) locomotor rating scale, before and after spinal hemisection at T13 level. We also examined lesion size in the spinal cord using Luxol fast blue/cresyl violet staining. One day after injury, KO and WT mice showed no significant difference in the motor function due to complete paralysis following spinal hemisection. However, when it compared to WT mice, KO mice had significantly delayed and decreased functional outcomes from 4 days up to 21 days after SCI. KO mice also showed significantly greater lesion size in the spinal cord than WT mice showed at 21 days after spinal hemisection. These results suggest that Hsp70 has a protective effect against traumatic SCI and the manipulation of the hsp70.1 gene may help improve the recovery of motor function, thereby enhancing neuroprotection after SCI.
