Purpose: To evaluate the role of 18F-FDG PET with contrast enhanced CT (PET-CECT) in early detection of recurrence in follow up patients of carcinoma cervix. Methods: Patients with histopathologically proven carcinoma cervix who underwent chemotherapy, radiotherapy and/or surgery and on follow up were recruited in the study. Fifty-two patients underwent 18F-FDG PET-CECT for detection of recurrence. The median age was 51.5 (average = 53.4) years. PET-CECT studies were evaluated and analyzed separately by an experienced nuclear medicine physician and a radiologist independently. The physicians were blinded for the patient history. PET-CECT results were validated with histopathological correlation, conventional radiologic imaging/follow up PET-CECT study and clinical follow up. Results: Out of 52 patients, 34 patients were reported as positive for recurrence, 17 of these were having active local recurrence and 31 patients had regional lymph nodal metastases, 14 patients had distant metastases (out of them 6 patients had distant lymph node metastases, 6 had pulmonary metastases, 4 had skeletal metastases and two had liver metastases). Remaining 18 patients were reported as negative for recurrence. The lung was the most common site for distant metastasis. Patient were then further evaluated based on histopathological correlation, conventional radiologic imaging and follow up PET-CECT scan and five were found to be false positive and one patient was identified as false negative. The sensitivity, specificity, positive and negative predictive value were derived to be 96.7%, 77.3%, 85.3% and 94.4%, respectively. Accuracy was calculated to be 88.5%. Conclusions: 18F-FDG PET-CECT is a very useful non-invasive modality for the early detection of recurrence and metastatic workup in patients with carcinoma cervix with a very high sensitivity and negative predictive value. It is also useful in targeting biopsy sites in suspected cases of recurrence.

Aims. Fibrous dysplasia (FD) is a benign fibro-osseous neoplasm that most commonly arises in the ribs, femur, and craniofacial bones. We analyzed features of FD arising in the spine/short tubular/small bones of the hands/feet (STSBHF), specifically assessing for pattern of bone formation (conventional, complex/anastomosing, psammomatoid/cementum like), myxoid change, and presence of osteoclast-type giant cells. Materials and methods. A total of 1958 cases of FD were reviewed, of which 131 arose in the spine/STSBHF representing 2.5% of institutional and 10% of consultation cases, respectively. Eighty-six cases had material available for review. Anatomic sites included vertebrae ( n = 58, 67%), short tubular bones ( n = 20, 23%), and small bones of the hands/feet ( n = 8, 9%). The most common morphologic pattern of bone identified was conventional ( n = 77, 90%), followed by complex/anastomosing ( n = 22, 26%) and psammomatoid/cementum like ( n = 22, 26%). Eighteen cases (21%) had matrix-poor areas. Hypercellular areas were identified in 6 cases, 2 cases of which showed matrix-poor areas. Osteoclast-type giant cells were noted in 9 cases and myxoid change was present in 3 cases. Radiologic imaging studies available for 41 cases nearly all demonstrated features typical of FD, but the diagnosis was not predicted due to the unexpected location. Conclusions. FD arising in the spine/STSBHF is rare and frequently results in expert consultation. A significant number of cases exhibited less commonly recognized patterns of bone formation, and stromal changes including osteoclast-type giant cells, and matrix poor areas. Furthermore, imaging features in the STSBHF are often less specific. Awareness of the morphologic spectrum at these locations coupled with radiologic correlation should aid in accurate classification.

Abstract Background The pedicled buccal fat pad has been used for a long time to reconstruct oral defects due to its ease of flap formation and few complications. Many cases related to reconstruction of defects in the maxilla, such as closing the oroantral fistula, have been reported, but cases related to the reconstruction of defects in the mandible are limited. Under adequate anterior traction, pedicled buccal fat pad can be a reliable and effective method for reconstruction of surgical defects in the posterior mandible. Case presentation This study describes two cases of reconstruction of surgical oral defects in the posterior mandible, all of which were covered by a pedicled buccal fat pad. The size of the flap was sufficient to perfectly close the defect without any tension. Photographic and radiologic imaging showed successful closure of the defects and no problems were noted in the treated area. Conclusion In conclusion, the pedicled buccal fat pad graft is a convenient and reliable method for the reconstruction of surgical defects on the posterior mandible.

ABSTRACT Background: Unlike in adults, there are currently no standardized, validated guidelines to aid practitioners in clearing the pediatric cervical spine (C-spine). Many pediatric centres in Canada have locally produced, adult-modified guidelines, but the extent to which these or other guidelines are used is unknown. Objective: The purpose of this study was to determine if Canadian physicians are using either locally produced or adult C-spine guidelines to clear the C- spines of patients < 16 years of age. The study also characterized the common methods used by physicians to clear pediatric C-spine injuries in terms of clinical examination and radiologic imaging. Methods: A 20-question survey was distributed to 240 Canadian pediatric emergency physicians and trauma team leaders using the Dillman Total Design Method. Results: The response rate was 68%. The results showed that 61% of physicians currently use guidelines to assist in the clearance of pediatric C-spines. Of those physicians not using guidelines, 85% stated that they would use them if they were available. The clinical criteria most often used to clear pediatric C-spines were a normal neurologic examination (97%) and the absence of C-spine tenderness (95%), intoxication (94%), and distracting injuries (87%). Conclusions: Guidelines are commonly used by Canadian physicians when clearing the pediatric C-spine, yet few are validated in children. Those most commonly used are locally developed guidelines, the Canadian C-spine guidelines, or National Emergency X-Radiography Utilization Study (NEXUS) low-risk criteria.

A prospective trial of mallet-finger injuries treated conservatively by elastic double-finger bandage showed no disadvantages compared to other kinds of conservative treatment. The method is agreeable for the patient, being hygienic and causing no kind of skin irritation.
