Supernumerary teeth in non-syndromic patients

Hyperdontia or supernumerary teeth without associated syndrome is a rare phenomenon, as supernumerary teeth are usually associated with cleft lip and palate or other syndromes such as Gardner's syndrome, cleidocranial dysplasia, and so on. Five patients with supernumerary teeth visited our department. They had no familial history or other pathology, certain treatment protocols was modified due to the presence of supernumerary teeth. Non-syndromic supernumerary teeth, if asymptomatic, need to have periodical radiographic observation. If they showed no variation as they impacted in the jaw, careful examination is necessary because they may develop into pathological status such as dentigerous cysts. The importance of a precise clinical history and radiographic examination for patients with multiple supernumerary teeth should be emphasized.     

System for Integrated Neuroimaging Analysis and Processing of Structure

Mapping brain structure in relation to neurological development, function, plasticity, and disease is widely considered to be one of the most essential challenges for opening new lines of neuro-scientific inquiry. Recent developments with MRI analysis of structural connectivity, anatomical brain segmentation, cortical surface parcellation, and functional imaging have yielded fantastic advances in our ability to probe the neurological structure-function relationship in vivo. To date, the image analysis efforts in each of these areas have typically focused on a single modality. Here, we extend the cortical reconstruction using implicit surface evolution (CRUISE) methodology to perform efficient, consistent, and topologically correct analyses in a natively multi-parametric manner. This effort combines and extends state-of-the-art techniques to simultaneously consider and analyze structural and diffusion information alongside quantitative and functional imaging data. Robust and consistent estimates of the cortical surface extraction, cortical labeling, diffusion-inferred contrasts, diffusion tractography, and subcortical parcellation are demonstrated in a scan-rescan paradigm. Accompanying this demonstration, we present a fully automated software system complete with validation data.     

A Clinician’s Role in the Management of Soft Tissue Injuries of the Face: A Clinical Paper

Introduction

Injuries of the facial soft tissues may be due to road traffic accidents, industrial injuries, domestic and interpersonal violence, dog bites, human bites, war injuries etc. They may be described depending on the depth of involvement of the soft tissue and/or region since it gives the clinician the method of treatment. The soft tissue injuries must take into the underlying skeletal injury into account since these injuries if carelessly handled they leave deformed scarring in the most precious and beautiful part of the body.

Materials and Methods

Various patients reporting to the department of Oral and Maxillofacial Surgery, Narayana Dental College and hospital, Nellore were included in the study. Injuries in the various aspects of face at various anatomical areas has been presented with the mode of management.

Conclusion

The maxillofacial surgeon while attending these cases should avoid the need for revision by having a thorough knowledge of the anatomy, physiology of the soft tissues and treat them accordingly after following good clinical and radiological examination.     

Lower eyelid suspension using polypropylene suture for the correction of punctal ectropion

ObjectiveTo evaluate the efficacy and complications of lower eyelid suspension with the modified Safdarjung hospital technique using 5:0 polypropylene suture for punctal ectropion.Study designProspective case series.MethodThirty one eyelids in 19 patients with mild and moderate ectropion and all types of laxity including involutional and paralytic were included. All patients underwent lower eyelid suspension with the modified Safdarjung hospital technique. A 5:0 polypropylene suture was passed in the pre-tarsal plane between the attachments of the lateral and medial canthal tendons near their insertion at the orbital rim. Successful outcome was judged by the anatomical restoration of the apposition of the punctum to the globe in the upward gaze and the physiological relief of epiphora. The recurrence of lid laxity, overall lid/globe apposition and complications were also noted.ResultsAt 1 year follow up anatomical success was achieved in 28 (90%) patients and functional success noted in 27 (87%) patients. Recurrence of lid laxity was noted in 2 patients. There was a suture exposure in one case and a suture granuloma in another case. The results did not correlate to the degree of ectropion and type of laxity.ConclusionLower eyelid suspension using 5:0 polypropylene suture is a useful procedure for the treatment of involutional and paralytic punctal ectropion. It is simple and effective with minimal complications. However, the effect on scleral show and the concern related to suture material biodegradation over years needs to be further evaluated.     

Pulmonary embolectomy with use of pediatric bronchoscope for the detection of residual emboli: an innovative surgical technique

Pulmonary embolectomy in the treatment of massive pulmonary embolus has been in doubt since the introduction of thrombolytic therapy. Recent indications for surgical intervention are- contraindication to thrombolysis, failed medical treatment and severe Right Ventricular (RV) dysfunction. A 54-year male came to us with complaints of palpitation, tachypnea and repeated syncope . Transthoracic echocardiography and Computed Tomography pulmonary angiogram demonstrated- Biatrial mass with right atrial mass extending into right ventricle and main pulmonary artery. Pulmonary embolectomy was performed. Residual emboli of bilateral pulmonary arteries were detected with a fiberoptic pediatric bronchoscope and removed. Bronchoscopic evaluation appears to be safe and useful for direct visual detection of emboli.     

Swan-Ganz entrapment during cardiac surgery – a case report

Inability to withdraw a Swan-Ganz catheter as a result of its intracardiac entrapment is a rare but serious complication. In a normal intracardiac course, the catheter tends to rest against the antero-lateral wall of the right atrium where the catheter may be caught by the suture during cannulation for Cardiopulmonary Bypass (CPB). Entrapment of a Swan-Ganz catheter by the left atriotomy suture is described in this case report.     

Role of Splenic Artery Embolization in Management of Traumatic Splenic Injuries: A Prospective Study

The objective of our study was to evaluate the role of splenic artery embolization (SAE) in the management of traumatic splenic injuries. From September 2008 to September 2010, a total of 67 patients underwent nonoperative management (NOM) for blunt splenic injuries. Twenty-two patients were excluded from the study because of associated significant other organ injuries. Twenty-five patients underwent SAE followed by NOM (group A) and 20 patients underwent standard NOM (group B). Improvement in clinical and laboratory parameters during hospital stay were compared between two groups using Chi-square test and Mann–Whitney test. SAE was always technically feasible. The mean length of the total hospital stay was lower in the group A patients (5.4 vs. 6.6 day, [P = 0.050]). There was significant increase in hemoglobin and hematocrit levels and systolic blood pressure (SBP) in group A patients after SAE, whereas in group B patients there was decrease in hemoglobin and hematocrit levels and only slight increase in SBP (pre- and early posttreatment relative change in hemoglobin [P = 0.002], hematocrit [P = 0.001], and SBP [P = 0.017]). Secondary splenectomy rate was lower in group A (4 % [1/25] vs. 15 % [3/20] [P = 0.309]). No procedure-related complications were encountered during the hospital stay and follow-up. Minor complications of pleural effusion, fever, pain, and insignificant splenic infarct noted in 9 (36 %) patients. SAE is a technically feasible, safe, and effective method in the management of splenic injuries. Use of SAE as an adjunct to NOM of splenic injuries results improvement in hemoglobin, hematocrit levels, and SBP. SAE also reduces secondary splenectomy rate and hospital stay.Keyword: Trauma, Splenic artery embolisation     

Lenalidomide before and after autologous stem cell transplantation for transplant-eligible patients of all ages in the randomized,phase III,Myeloma XI trial

The optimal way to use immunomodulatory drugs as components of induction and maintenance therapy for multiple myeloma is unresolved. We addressed this question in a large phase III randomized trial, Myeloma XI. Patients with newly diagnosed multiple myeloma (n=2,042) were randomized to induction therapy with cyclophosphamide, thalidomide, and dexamethasone (CTD) or cyclophosphamide, lenalidomide, and dexamethasone (CRD). Additional intensification therapy with cyclophosphamide, bortezomib, and dexamethasone (CVD) was administered before autologous stem-cell transplantation to patients with a suboptimal response to induction therapy using a response-adapted approach. After receiving high-dose melphalan with autologous stem cell transplantation, eligible patients were further randomized to receive either lenalidomide alone or observation alone. Co-primary endpoints were progression-free survival (PFS) and overall survival (OS). The CRD regimen was associated with significantly longer PFS (median: 36 vs. 33 months; hazard ratio [HR], 0.85; 95% confidence interval [CI]: 0.75-0.96; P=0.0116) and OS (3-year OS: 82.9% vs. 77.0%; HR, 0.77; 95% CI: 0.63-0.93; P=0.0072) compared with CTD. The PFS and OS results favored CRD over CTD across all subgroups, including patients with International Staging System stage III disease (HR for PFS, 0.73; 95% CI: 0.58-0.93; HR for OS, 0.78; 95% CI: 0.56-1.09), high-risk cytogenetics (HR for PFS, 0.60; 95% CI: 0.43-0.84; HR for OS, 0.70; 95% CI: 0.42-1.15) and ultra-high-risk cytogenetics (HR for PFS, 0.67; 95% CI: 0.41-1.11; HR for OS, 0.65; 95% CI: 0.34-1.25). Among patients randomized to lenalidomide maintenance (n=451) or observation (n=377), maintenance therapy improved PFS (median: 50 vs. 28 months; HR, 0.47; 95% CI: 0.37-0.60; P<0.0001). Optimal results for PFS and OS were achieved in the patients who received CRD induction and lenalidomide maintenance. The trial was registered with the EU Clinical Trials Register (EudraCT 2009-010956-93) and ISRCTN49407852.
