  • Objectives: This retrospective study aims to evaluate the prevalence of maxillofacial trauma in a developing country, along with its pattern, etiology and management. Data for the present study were collected from the Department of Dentistry, ESIC Medical College and Post Graduate Institute of Medical Sciences and Research, Chennai in India. Materials and Methods: The medical records of patients treated for maxillofacial injuries between May 2014 and November 2015 were retrospectively retrieved and analyzed for prevalence, pattern, etiology, and management of maxillofacial trauma. SPSS software version 16.0 was used for the data analysis. Results: Maxillofacial fractures accounts for 93.3% of total injuries. The mean and standard deviation for the age of the patients were $35.0{\pm}11.8$ years and with a minimum age of 5 years and maximum age of 75 years. Adults from 20 to 40 years age groups were more commonly involved, with a male to female ratio of 3:1. There was a statistically significantly higher proportion of males more commonly involved in accident and injuries (P <0.001). Conclusion: The most common etiology of maxillofacial injury was road traffic accidents (RTA) followed by falls and assaults, the sports injuries seem to be very less. In RTA, motorized two-wheelers (MTW) were the most common cause of incidents. The majority of victims of RTA were young adult males between the ages of 20 to 40 years. The malar bone and maxilla were the most common sites of fracture, followed by the mandible. The right side of the zygomatic complex was the predominant side of MTW injury. The majority of the zygomatic complex fractures were treated by conservative management. Open reduction and internal fixation were performed for indicated fracture patients.

  • Purpose: The aim of this study was to evaluate the clinical significance of inflammatory biomarkers in acute infectious diarrhea among children. Methods: Clinical parameters including fever, bacterial and viral etiology based on stool culture and multiplex polymerase chain reaction, and nine biomarkers including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and leukocytes in blood and calprotectin, lactoferrin, myeloperoxidase, polymorphonuclear elastase, leukocytes, and occult blood in feces were evaluated in children who were hospitalized due to acute diarrhea without underlying disease. Results: A total of 62 patients were included. Among these patients, 33 had fever, 18 showed bacterial infections, and 40 patients were infected with 43 viruses. Of all the biomarkers, CRP was significantly correlated with fever (p<0.001). CRP, ESR, calprotectin, lactoferrin, myeloperoxidase, fecal leukocytes, and occult blood were significantly associated with infection with bacterial pathogens (p<0.001, p=0.04, p=0.03, p=0.003, p=0.02, p=0.03, p=0.002, respectively). The combination of CRP and fecal lactoferrin at their best cut-off values (13.7 mg/L and $22.8{\mu}g/mL$, respectively) yielded a sensitivity of 72.2%, and a specificity of 95.5% for bacterial etiology compared with their individual use. Conclusion: Blood CRP is a useful diagnostic marker for both fever and bacterial etiology in acute pediatric diarrhea. The combination of CRP and fecal lactoferrin yields better diagnostic capability for bacterial etiology than their use alone for acute diarrhea in children without underlying gastrointestinal disease.

  • This study was carried out through the investigation of Oriental and Western medical literature and we was discovered these conclusions about the etiology, treatment, prescription of habitual abortion. The result of this study were as follows : 1. The habitual abortion does agree with 'Hwaltae(滑胎)' and means that spontaneous abortion repeats three times or more. 2. The etiology of habitual abortion is divided 'Deficiency of kidney'(腎虛), 'Deficiency of vital energy and blood'(氣血虛弱), 'Deficiency of yin'(陰虛), 'Clotted blood'(瘀血). 3. By means of cause, the treatment of habitual abortion was mainly made use of 'Tonifying kidney and promoting spleen'(補腎健脾), 'Invigorating vital energy and nourishing blood'(補氣補血), 'Supplementing yin fluid and alleviating fever'(滋陰淸熱), 'Resuscitating blood and removing clotted blood'(活血祛瘀). 4. By means of cause, the prescription of habitual abortion was frequent made use of Bosingochunghwan(補腎固沖丸), Bosingotae$\breve{u}$m(補腎固胎飮), Taesanbans$\breve{o}$ksan(泰山磐石散), $Ch\breve{o}ng\breve{u}mboinghwan$(千金保孕丸), Agyotang(阿膠湯), Gungguibojungtang(芎歸補中湯), Taewon$\breve{u}$m(胎元飮), Gotaej$\breve{o}$n(固胎煎), Baekchulj$\breve{o}$n(白朮煎), Sas$\breve{o}$ngsan(四聖散), Gyegibokryonghwan(桂枝茯苓丸), $Dangguich\breve{o}ng\breve{u}mtang$(當歸千金湯). 5. The Western medical etiology of habitual abortion(recurrent spontaneous early pregnancy loss) is divided Genetic factor(Chromosome aberration), Anatomical deformity, Endocrinologic disorder, Infection, Immunologic factor, Unknown factor(Others).

  • Arachidonic acid (AA) is a polyunsaturated fatty acid that is a normal constituent of membrane lipids in animal cells. In addition to its role as a precursor of prostaglandins, AA itself may play an important role in the regulation of cell function. The effect of AA on functions of granulosa cells was investigated in pre-hierarchical small yellow follicles of laying hens. Immuno-cytochemical staining showed that AA ($10^{-7}-10^{-5}$ M) increased the expression of the extracellular matrix glycoprotein laminin, gap junction connexin 43 and protein kinase C (PKC). Therefore, mediated by the PKC signal pathway, AA may regulate the intercellular communication of granulosa cells and follicular development by increasing the expression of laminin and connexin.

  • Clinical and pathologic data were reviewed in 20 patients who had have surgery for isolated aortic valvular heart disease between April 1978 and April, 1987. Hospital mortality was 10%, with no additional late mortality during a mean follow-up period of 24.1 months. Prosthetic valve failure developed in 3 patients and two had reoperation. Niety four percent of the survivors who were in NYHA Funtional class III or IV before operation are now in class I or II. Ninety percent of all patients are still alive at a maximum follow up of 9 years. The clinical histories, gross and histologic examination of valves estabilished the causes for isolated aortic valve disease: 3 rheumatic, 2 congenital bicuspid, 2 hypertention, 2 aortitis and each one case of floppy valve, medial cystic necrosis of aorta, bacterial endocarditis. But etiology was unknown in 8 cases. Sixteen patietns had myxoid degeneration, defined as significant disruption of the valve fibrosa and its replacement by acid mucosaccharides and cystic changes. Myxoid degeneration was also the primary pathologic abnormality in the patients with 2 hypertention, 2 rheumatic, 1 aortitis, 1 bacterial endocarditis, 1 floppy valve, 1 congenital bicuspid. The patients with myxoid degeneration of uncertain origin were 8. Histologic finding of all of them revealed nonspecific patients with myxoid degeneration of uncertain orgin were 8. Histologic finding of all of them revealed nonspecific chronic valvulitis with myxoid degeneration. This finding may indicate that the etiology w uld be infectious.

  • In the time period 1996-2004, all incident cases of bladder cancer were included in a case-control study in order to study the role of meat consumption and product animals in the etiology of urothelial cancer. The study included 225 cases and 1,510 hospitalized controls with non-neoplastic conditions, not related to smoking and alcohol drinking. Relative risks, approximated by the odds ratios, were calculated in order to clarify the effect of meat consumption in the etiology of urothelial cancer. Total meat consumption (OR 1.47, 95% CI 1.02-2.11), total processed meat (OR 1.57, 95% CI 1.08-2.27), frankfurters (hot dogs) (OR 2.03, 95% CI 1.28-3.21), ham (OR 1.79, 95% CI 1.21-2.67) and salted meat (OR 2.73, 95% CI 1.78-4.18) were positively associated with risk of bladder cancer. Animal products, like cheese, whole milk, and total eggs were also associated with bladder cancer risk (OR for eggs 4.05, 95% CI 2.68-6.12). In conclusion, total meat, processed meat, and eggs could play an important role in the etiology of bladder cancer in Uruguay.

  • The etiology and pathophysiology of delayed inflammatory reactions caused by hyaluronic acid fillers have not yet been elucidated. Previous studies have suggested that the etiology can be attributed to the hyaluronic acid filler itself, patient's immunological status, infection, and injection technique. Hyaluronic acid fillers are composed of high-molecular weight hyaluronic acids that are chemically cross-linked using substances such as 1,4-butanediol diglycidyl ether (BDDE). The mechanism by which BDDE cross-links the two hyaluronic acid disaccharides is still unclear and it may exist as a fully reacted cross-linker, pendant cross-linker, deactivated cross-linker, and residual cross-linker. The hyaluronic acid filler also contains impurities such as silicone oil and aluminum during the manufacturing process. Impurities can induce a foreign body reaction when the hyaluronic acid filler is injected into the body. Aseptic hyaluronic acid filler injections should be performed while considering the possibility of biofilm formation or delayed inflammatory reaction. Delayed inflammatory reactions tend to occur when patients experience flu-like illnesses; thus, the patient's immunological status plays an important role in delayed inflammatory reactions. Large-bolus hyaluronic acid filler injections can induce foreign body reactions and carry a relatively high risk of granuloma formation.

  • Background: The use of extracorporeal life support (ECLS) in the setting of cardiopulmonary resuscitation (CPR) has shown improved outcomes compared with conventional CPR. The aim of this study was to determine factors predictive of survival in extracorporeal CPR (E-CPR). Methods: Consecutive 85 adult patients (median age, 59 years; range, 18 to 85 years; 56 males) who underwent E-CPR from May 2005 to December 2012 were evaluated. Results: Causes of arrest were cardiogenic in 62 patients (72.9%), septic in 18 patients (21.2%), and hypovolemic in 3 patients (3.5%), while the etiology was not specified in 2 patients (2.4%). The survival rate in patients with septic etiology was significantly poorer compared with those with another etiology (0% vs. 24.6%, p=0.008). Septic etiology (hazard ratio [HR], 2.84; 95% confidence interval [CI], 1.49 to 5.44; p=0.002) and the interval between arrest and ECLS initiation (HR, 1.05 by 10 minutes increment; 95% CI, 1.02 to 1.09; p=0.005) were independent risk factors for mortality. When the predictive value of the E-CPR timing for in-hospital mortality was assessed using the receiver operating characteristic curve method, the greatest accuracy was obtained at a cutoff of 60.5 minutes (area under the curve, 0.67; 95% CI, 0.54 to 0.80; p=0.032) with 47.8% sensitivity and 88.9% specificity. The survival rate was significantly different according to the cutoff of 60.5 minutes (p=0.001). Conclusion: These results indicate that efforts should be made to minimize the time between arrest and ECLS application, optimally within 60 minutes. In addition, E-CPR in patients with septic etiology showed grave outcomes, suggesting it to be of questionable benefit in these patients.
