Purpose： To evaluate the functional and radiological outcome of comminuted radial head fractures, which were not amenable for classical open reduction with internal fixation, treated by on-table reconstruction and fixation using low profile plates. Methods： We reviewed 6 patients of Mason type Ill radial head fractures treated by on-table recon- struction technique between 2011 and 2013. There were 5 men and 1 woman with a mean age of 35 years （range 25-46 years）. All surgeries were carried out at our tertiary care level 1 trauma centre within a mean of 3 days （range 1-8 days） from date of injury using on-table reconstruction technique. The functional outcome was measured using elbow functional rating index described by Broberg and Morrey and the patient-based Disabilities of the Arm, Shoulder and Hand （DASH） outcome measure. Results： The mean follow-up period was 25 months, The average elbow flexion was 135~ （range 125~ -140~） and the average flexion contracture was 5~ （range 0-10~）. The average supination and pronation was 75~ （range ？0o-80~） and 70~ （range 65^-82~） respectively. According to Broberg and Morrey scoring system, the average score was 90 points （range 75-100）. The mean DASH score was 2.49 points, Conclusion： On-table reconstruction and fixation of comminuted radial head fractures using low profile plates is a reasonable option. The reconstructed radial head acts as spacer and provides reasonably good results and no surgical intervention is required for asymptomatic nonunion of these fractures regardless of the radiological findings.

Introduction: The median survival for patients with stage IV rectal cancer is approximately 20 months. Therapy should focus not only on improving survival but also on quality of life. The aim of our study was to determine if chemoradiation (C-RT) would improve palliation for metastatic unresectable locally advanced disease compared to patients receiving palliative chemotherapy alone (C) for stage IV cancer. Methods: Retrospective review of a prospectively maintained database at a single institution was carried out under IRB approval. From January 2004 to December 2008, 43 patients presenting with unresectable stage IV rectal cancer were identified with a median follow-up of 12 months. Patients with evidence of locally advanced disease or bulky disease received infusional 5-FU ± bevacizumab and 3D conformed mega voltage photon therapy (5400 cGy). Patients without evidence of bulky disease received either FOLFOX or FOLFIRI ± bevacizumab. Data on demographics, investigations, treatment, complications, metastasis, number of blood transfusions, days of hospitalization, and surgical intervention were analyzed using SPSS statistical software. p y significant. Results: There were 25 and 18 patients in the C and C-RT groups respectively. There was no difference in mean age, sex or overall survival. Three patient (12%) in the C group developed hydronephrosis compared to 8 patients (44%) in the C-RT group (p y in the C group compared to 9 patient (50%) in the C-RT group (p = 0.07). In the C arm, 80% of patients required multiple hospitalizations for symptoms consistent with progression of disease compared to 61% of patients in the C-RT arm (p y advanced unresectable stage IV cancer has not been extensively investigated. At our institution, patients treated with C-RT for bulky stage IV rectal cancer required fewe

Squamous inclusion cyst is a rare benign cystic lesion most commonly affecting the floor of mouth in the oral cavity. Its presence in the palatine tonsil of the oropharynx is an extremely rare occurrence. We highlight a case of an elderly female who was histopathologically diagnosed as squamous inclusion cyst of the palatine tonsil. We shall discuss the presentation, diagnosis, management and postoperative follow-up of the case.

Background: The high power output necessary for insect flight has driven the evolution of muscles with large myofibrils (primary energy consumers) and abundant mitochondria (primary energy suppliers). The intricate functional interrelationship between these two organelles remains largely unknown despite its fundamental importance in understanding insect flight bioenergetics. Unlike vertebrate muscle that relies on a phosphagen (creatine phosphate/creatine kinase) system to regulate high energy phosphate flux, insect flight muscle has been reported to lack mitochondrial arginine kinase (analogous to creatine kinase), a key enzyme that enables intracellular energy transport. Creatine kinase is known to interact with mitochondrial adenine nucleotide translocase (ANT) in the transfer of ADP and ATP into and out of the mitochondria. Results: Here, we use quantitative immunogold transmission electron microscopy to show that in Drosophila melanogaster indirect flight muscles (IFM), ANT is present in the mitochondria as well as throughout the myofibril. To confirm this unexpected result, we created a transgenic line that expresses a chimeric GFP-ANT protein and used an anti-GFP antibody to determine the intracellular distribution of the fusion protein in the IFM. Similar to results obtained with anti-ANT, the fusion GFP-ANT protein is detected in myofibrils and mitochondria. We confirmed the absence of arginine kinase from IFM mitochondria and show that its sarcomeric (i.e., intramyofibrillar) distribution is similar to that of ANT. Conclusions: These results raise the possibility that direct channeling of nucleotides between mitochondria and myofibrils is assisted by an ANT protein thereby circumventing the need for a phosphagen shuttle in the IFM. The myofibrillar ANT may represent a unique adaptation in the muscles that require efficient exchange of nucleotides between mitochondria and myofibrils.
