Background and Purpose: The odontogenic keratocyst (OKC) is an unusual cyst with a high recurrence rate. The most common site for OKCs is by far the mandible. The best treatment of OKC remains controversial. Recurrence rates ranging anywhere from less than 10% to more than 60% have been reported. The aim of our study was to evaluate marsupialization as a treatment option for OKC. Methods: We managed 13 patients (8 male, 5 female) between the ages of 16 and 31 years (mean, 22.4 y) with biopsy-proven OKC. Radiographically, the patients' cyst sizes were between 25 and 90mm. Treatment consisted of marsupialization. We followed up with patients for a total duration of at least 60 months, and posttreatment visits were carried out at 6-month intervals. Results: We documented cured or reduced cyst size with radiography. The odontogenic keratocyst resolved completely in 10 patients, and the cyst walls shrank in 3 patients. The latter patients required a second operation to remove the associated impacted teeth. A histologic evaluation of 3 lesions showed metaplasia. Any case of recurring cysts was not seen during the entire follow-up period. Conclusions: Marsupialization is an effective and conservative treatment option for OKC. Nevertheless, future studies should conduct even longer follow-up periods to evaluate any recurrence of lesions. Copyright © 2012 by Mutaz B. Habal, MD.

Masseter muscle hypertrophy is characterized by unilateral or bilateral enlargement of the masseter muscles affecting both females and males after puberty. Limitations on mouth opening, swollen cheek, and also tension in the region of the hypertrophied muscle are symptoms reported. Also, masseter hypertrophy can cause aesthetic and functional problems. A 40-year old woman was referred to our clinic with the chief complaint of facial appearance with square-face type. To eliminate undesirable facial appearance, surgical intraoral approach compromising reduction of deep masseter muscle with monocortical and bicortical ostectomy of the angle of the mandible was performed. The patient was satisfied with both functional outcomes and aesthetic outcomes on both facial profile and frontal view. No complication was seen intraoperatively and postoperatively after a 12-month follow-up period. This treatment modality would be suggested to gain optimal aesthetic results especially in a square face from the lateral profile. © 2012 Mutaz B. Habal, MD.

Nonossifying fibromas (NOFs) are benign lesions that unusually occur in the mandible. Nonossifying fibromas are asymptomatic and spontaneous resolution at skeletal maturity. Nonossifying fibromas associated with aneurysmal bone cyst (ABC) are very rare. In this clinical report, NOF secondary to ABC in the mandibular condyle was reported; however, it presents different clinical behavior than the usual NOF. In this case, severe destruction in the mandibular condyle as a characteristic of NOF was seen. In the follow-up period, no recurrence was seen subsequent to treatment of lesion with complete resection. Treatment of NOFs with secondary ABC would require aggressive intervention than the treatment of usual NOF. Copyright © 2011 by Mutaz B. Habal, MD.

The purpose of this study is to explore the effects of grape seed oil on growth performance, some blood parameters and fatty acid composition in broiler meat. In order to formulate isocaloric ratios, the corresponding amounts of soy oil were excluded from the rations accordingly with the addition of 0, 5, 10 and 15 g grape seed oil per kg. Four treatment groups were formed each consisting of 20 birds with similar initial body weights. Feed and water were given ad libitum. At the end of the experiment, no statistically significant difference was identified among the groups with respect to body weight gain, feed consumption and blood parameters (P>0.05). Feed conversion rate was improved in the group supplemented with 15g/kg grape seed oil (P<0.05). Grape seed oil inclusion was determined to be quadratically significant for carcass yield (P<0.05). The use of grape seed oil in the ration significantly increased the levels of C17:1 heptadecanoic acid, C18:3 linoleic acid and C20:1 eicosenoic acid in the meat which is known to have health-promoting effects for humans (P<0.05). The results have shown that nutritional composition of diets could affect the fatty acid composition of broiler meat. Hence, the findings of the study support the potential use of grape seed oil in functional broiler meat production for human nutrition, particularly for those with cardiovascular diseases. © 2014 National Centre for Agrarian Sciences.

Objectives: The main purpose of this study was to determine the prognosis and outcomes of the patients with bilateral temporomandibular disorder which underwent bilateral temporomandibular joint surgery in a consecutive number of patients in a retrospective study. Study Design: Sixty five patients with 130 bilateral TMJ were included the study with selection from consecutive 256 TMJ who were treated with open surgery who do not respond to conservative treatment. 65 were divided in 3 main groups according clinical diagnosis bilateral TMJ site. In first group comprised 29 with 48 TMJ, was bilaterally presence anterior disc displacement with reduction (ADDR). second 19 with 26 TMJ, bilateral TMD consisted of anterior disc displacement without reduction (ADDNR) on both site. In the third group comprised 27 with 46 TMJ, bilaterally TMD consist ADDR on one site ADDNR another The patients in three different groups were operated either high condylectomy alone or high condylectomy with additional surgical procedures. Results: In the evaluation of pain relief, clicking, crepitation, headache, marked improvement was determined in all groups, but it was statistically insignificant comparison 3 groups. Slight increase maximal mouth opening was determined in the mean values of the 3 groups and also in the comparison of 3 groups it was not significant. Conclusions: These similar succesfull outcomes bilateral TMD with respect TMJ surgical procedures were obtained in 3 main groups although different diagnosis on the patients' groups was present. © Medicina Oral S.

This is a retrospective study with the aim to evaluate orbital floor reconstruction with autogenous bone and alloplastic materials consisting of Medpor, Medpor Titan, Titanium, and resorbable plates. We evaluated 101 patients with pure blow-out fracture or concomitant with zygomatic maxillary fracture. We reviewed patients' documentation before and after surgery and 12 months after reconstruction. Thirteen patients with Medpor, 42 patients with Medpor Titan, 30 patients with Titanium, 5 patients with calvarial bone graft, 8 patients with iliac bone graft, and 3 patients with bioresorbable plates were treated. Medpore and Medpor-Titan-Medpor 1.5 to 2 mm in thickness were used. Autogenous bone graft 3 to 5 mm in thickness was used. Results showed that autogenous and alloplastic materials could be used in orbital floor reconstruction; autogenous bone graft had minimal postoperative infection, and it is a good choice in major orbital defects. Titanium mesh and MTM with excellent structural support are used in large orbital floor defects. Resorbable plates are good alternative materials in pediatric patients. © 2010 by Mutaz B.

Hyperglycemia plays a critical role in the development and progression of diabetic encephalopathy. A few studies have focused on a disintegrin and metalloprotease with thrombospondin type I repeats-13 (ADAMTS-13) expression in the central nervous system (CNS), and its function continues to remain unclear. The purpose of this study was to compare the expression of ADAMTS-13, neuron specific enolase (NSE), neurofilament (NF), neuronal nitric oxide synthase (nNOS) and glial fibrillary acidic protein (GFAP) in brain tissues of experimental streptozotocin (STZ)-induced diabetic rats. Expression of ADAMTS-13 (P < 0.001), nNOS (P < 0.001), NSE (P < 0.001) and NF (P < 0.001) expressions in the brain tissue markedly increased while GFAP decreased (P < 0.001) in diabetic animals versus controls. The most prominent finding of our study was that ADAMTS-13 expression increased significantly, suggesting that it may play an important function/s in the regulation and protection of the blood-brain barrier integrity and central nervous system microenvironment in diabetes. The results also suggested that nitric oxide production may increase due to increased nNOS expression and this also might contribute to neuropathology related with diabetes. Furthermore, increased expression of ADAMTS-13, NSE, NF and decreased expression of GFAP may give an idea of the disease progress and thus may have a critical diagnostic significance. To the best of the authors' knowledge, this is the first report on ADAMTS-13 expression in the CNS of STZ-induced diabetic animals.

Inflammatory myofibroblastic tumor (IMT) is a distinct pseudosarcomatous lesion arising in the soft tissues and interior organs of children and young adults. It is rarely seen in adults. It was first described in lungs. IMT can occur in any location in the body. However, it is seen most commonly in lungs, intestinal mesentery and liver. Non-mesenteric alimentary tract IMT’s are quite rare. The presented case is an ileal IMT that caused small bowel invagination. A 38 year-old male patient presented to the emergency department with the complaint of diffuse abdominal pain, distension and no passage of gas or stools for two days. An bdominal examination revealed distension and tenderness in the abdomen with no guarding or rebound tenderness. Computerized tomography (CT) of the abdomen was ordered. CT revealed an image compatible with invagination of the right lower quadrant of the abdomen and a mass inside the lumen measuring 4×3×3cm. The mass causing invagination was detected during the surgical operation. A segmentary small bowel resection and ileoileal anastomosis was performed. The patient was discharged uneventfully on the postoperative sixth day. The diagnosis of IMT was confirmed histologically and immunochemically. © 2016, Professional Medical Publications.

To evaluate retrospectively demographic, clinical and histopathological variables effective on mortality in patients who had undergone emergency surgery due to complicated colorectal cancer.A total of 39 patients underwent urgent surgical interventions due to complicated colorectal cancer at the Department of General Surgery, Dursun Odaba Medical Center, between January 2010 and January 2015. Thirty three of these were included in the study. Six patients were excluded because complete medical records had been missing. Medical records of the 33 cases were retrospectively reviewed.There were 14 (42.5%) male and 19 (57.5%) female patients. Mean age was 60 years (range: 32- 83 years); 14 (42.5%) patients were less than 60 years old , while 19 (57.5%) were 60 years old or older. Operations were performed due to perforation (39.3%) and obstruction (60.6%) in 13 and 20 patients, respectively. Tumor localization was in the right and transverse colon in nine (21.2%) and in the left colon in 24 cases (72.7%). Eleven (33.3%) patients underwent resection and anastomosis, 13 (39.3%) resection and ostomy, and nine (27.2%) patients underwent ostomy alone without any resection. Postoperative mortality occurred in nine cases (27.2%).High mortality should be expected in females older than 60 years with a left sided colon tumor or with another synchronous tumor and in perforated tumors. Unnecessary major resections should be avoided and primary pathology should be in the focus of treatment in order to decrease the mortality and morbidity rates.
