Assessment of dental anxiety and its correlation with denture satisfaction in edentulous patients

Objective: The objectives of this study were to measure the level of dental anxiety and its correlation with dental history, denture satisfaction and other variables. Materials and methods: A cross-sectional study was conducted on 150 completely edentulous patients reporting to the Department of Prosthodontics, KLES's Institute of Dental Sciences, Belgaum, over a period of 17 months (August 2005 to March 2007). The anxiety level of the patients was assessed with the help of a questionnaire, after obtaining an informed consent. Reliability of the dental anxiety scale was assessed by means of coefficient alpha. Results: The results of this study concluded that dental anxiety scale for edentulous patients was a reliable scale for measuring dental anxiety. The anxiety score was higher for female than male patients. A significant correlation was found between denture satisfaction score and anxiety. Discussion: Anxiety plays a major role in denture satisfaction. The variables included: Previous denture experience, occupation, medical history, age, gender, dental anxiety scale, period of edentulousness, age of previous dentures, number of complete dentures, denture satisfaction score, and the score on the Hamilton anxiety scale Conclusion: The study indicated that gender correlates significantly with dental anxiety. Patients with medical history were found to be more anxious than normal patients. Patients with higher anxiety values were less satisfied with the treatment. Lastly, subjects with higher general anxiety showed greater values on the dental anxiety scale. Clinical significance: The assessment of dental anxiety will help the prosthodontist in the management of anxious patients and secondly to provide evidence-based research into this psychological construct which has been shown to predict dental avoidance.

Endoscopic ultrasound‐guided fine‐needle aspiration diagnosis of large cell neuroendocrine carcinoma of the gallbladder and common bile duct: Report of a case

Endoscopic ultrasound‐guided fine‐needle aspiration (EUS‐FNA) allows a reliable and accurate diagnosis of neoplasms of the gallbladder and bile ducts. We report the cytopathologic findings of a case of large cell neuroendocrine carcinoma (LCNEC) of the gallbladder and extrahepatic bile ducts in a 67‐year‐old woman who presented with progressive abdominal pain and jaundice. EUS‐FNA of the mass involving the common bile duct and of a porta hepatis lymph node showed abundant cellularity with tumor cells arranged singly and occasionally in tight and loose clusters and rosette‐like structures in a background showing extensive necrotic debris. The tumor cells were predominantly plasmacytoid, showed a moderate amount of focally vacuolated cytoplasm and large round to oval hyperchromatic nuclei with prominent nucleoli, numerous mitoses, and apoptotic bodies. The differential diagnosis included poorly differentiated adenocarcinoma, lymphoma, melanoma, and poorly differentiated neuroendocrine carcinoma (NEC), large cell type. The tumor cells were strongly and diffusely positive for cytokeratin AE1/AE3, CD56, synaptophysin, and chromogranin and showed a very high proliferative fraction on Ki67 staining, supporting the diagnosis of a high‐grade NEC. Due to the large size of the neoplastic cells, moderate amounts of cytoplasm and prominent nucleoli, a diagnosis of LCNEC was made on the EUS‐FNA sample. Despite the prompt institution of chemotherapy, the patient died shortly thereafter and the diagnosis was confirmed at autopsy. This is to our knowledge the first case of LCNEC of the gallbladder and bile ducts diagnosed by EUS‐FNA. Diagn. Cytopathol. 2013;41:1091–1095. © 2012 Wiley Periodicals, Inc.     

Large platelet aggregates in endoscopic ultrasound‐guided fine‐needle aspiration of the pancreas and peripancreatic region: A clue for the diagnosis of intrapancreatic or accessory spleen

Intrapancreatic and intraabdominal accessory spleens (IPIASs) are rarely encountered in endoscopic ultrasound‐guided fine‐needle aspiration (EUS‐FNA) biopsies. However, as incidentally discovered IPIAS can mimic a benign or malignant pancreatic neoplasm on imaging studies, a definitive diagnosis made by EUS‐FNA can avert an unnecessary surgical intervention or additional radiologic follow‐up. We report five cases of intrapancreatic splenules and one case of accessory spleen (AS) in which a definitive diagnosis was made on EUS‐FNA. Previously recognized FNA cytomorphologic features of splenic tissue, including ASs and splenosis, are endothelial cells and polymorphous lymphocytes admixed with neutrophils, eosinophils, plasma cells, histiocytes, and lymphoglandular bodies. We describe the additional finding of abundant large platelet aggregates as another distinguishing feature of splenic tissue on FNA. In all six cases, large platelet aggregates were identified along with polymorphous lymphoid cells, lymphoglandular bodies, loose aggregates of endothelial cells and scattered or aggregated bland spindle cells. A review of 10 consecutive cases of EUS‐FNA‐sampled benign intraabdominal lymph nodes showed that the presence of large platelet aggregates, three‐dimensional aggregates of lymphoid cells and of bland slender spindle cells and the absence of follicular germinal cell components (tingible body macrophages and lymphohistiocytic aggregates) are useful in differentiating IPIASs from reactive lymph nodes. Immunoperoxidase stains were useful to confirm a suspected IPIASs by showing CD31‐positive acellular flocculent material, consistent with large platelet aggregates and a rich CD8‐positive endothelial cell network between CD45‐positive lymphoid cells and CD68‐positive histiocytes in all six cases.

Intraocular endoscopy: A review

Optimal visualization is one of the most challenging aspects of performing vitreoretinal surgery. In situations where conventional microscopic techniques provide poor posterior visualization, the adjunctive skill set of endoscopic visualization may be needed. This allows for by-passing the opaque anterior segment media and getting access to the posterior segment pathology. Endoscopic vitrectomy is a useful and unique adjunct to microincision vitreoretinal surgery. The optical set-up of endoscopy allows for clinical approaches that are impossible with regular microscope viewing systems. These include the ability to observe across optically significant anterior segment opacities and directly visualize the posterior segment of the eye. It also allows for visualizing the difficult-to-access retroirideal, retrolental, and anterior retinal structures. Surgical access to anatomic spaces like the pars plana, pars plicata, ciliary sulcus, ciliary body, and peripheral lens is tedious. This is made simpler by endoscopy. In this review, we summarize and review the usage of the intraocular endoscope as a diagnostic and therapeutic armamentarium across a wide spectrum of ocular pathologies.     

Endoscopic visualization-assisted corneal bee sting removal

Purpose:Deeply embedded corneal foreign bodies and intrastromal foreign body removal can often be a challenge. The aim of this report was to describe the utility of endoscopy in visualization and removal of an embedded corneal bee stinger.Methods:A 44-year-old male patient developed toxic keratopathy after injury from a bee stinger. On examination, the bee stinger was noted to be deeply embedded in the corneal stroma. A superficial keratectomy was initially attempted; however, the stinger was noted to be intrastromal and protruding into the anterior chamber and could not be removed. An Endoscopy-assisted visualization was used to remove the stinger.Results:The bee stinger was successfully removed and the patient''s vision improved to 20/100 from an initial CFCF (counting fingers close to face) at time of presentation. At the end of 3 months follow-up, there was residual corneal edema along with cataractous changes in the lens as a sequelae of the initial bee sting injury. The patient subsequently underwent an endothelial keratoplasty along with phacoemulsification with intraocular lens implantation and the final BCVA improved to 20/40.Conclusion:Endoscopyassisted visualisation of anterior chamber and angle structures can be valuable in removal of retained and deeply embedded corneal or intracameral foreign bodies.     

Tracheal Stenting has Minimal Impact on Survival in Anaplastic Thyroid Carcinoma

Background

Anaplastic thyroid carcinoma (ATC) is the most aggressive form of thyroid cancer and it has an extremely poor prognosis. Rapid airway compromise is the main cause of death in patients with ATC.

Methods

The present study is based on a retrospective review of clinical data of patients with ATC treated over the last decade in a tertiary referral center.

Results

Between January 1998 and December 2010, 31 patients (13 males: 18 females) with a mean age of 74 years (range: 54–90 years) had a diagnosis of ATC made on fine-needle aspiration (n = 29) or biopsy (n = 2). Eight patients underwent total thyroidectomy and lymph node dissection, and five patients had attempted surgery but the procedure was abandoned because of inoperability. Airway compromise was clinically apparent in 11 patients. Five patients had tracheal stents inserted, with a median survival of 2 months (range: 1–36 months). In the whole cohort, 29 patients died of the disease, with a mean survival of 7 months (range: 1–36 months).

Conclusions

Survival of patients with undifferentiated thyroid cancer is severely compromised by airway obstruction. Palliation with tracheal stenting can rescue catastrophic airway obstruction but offers minimal survival benefit.     

Penile Incarceration with Metallic Foreign Bodies: Management and Review of Literature

Introduction

Penile strangulation from constricting metallic objects disorders is an uncommon urological emergency which requires prompt intervention to prevent complications. The treatment modalities are diverse and characterized by lack of consensus.

Material and Methods

Three cases with penile incarceration due to constricting metallic objects who presented to our department were included in this study. All 3 patients required different management options highlighting the diversity of clinical presentation and need for customization of treatment as per the clinical scenario.

Results

The 3 patients required different approach for treatment. First patient could be managed by degloving of penile skin while second patient required mechanical removal of the foreign body and debridement of local necrotic tissues. The third patient had to undergo excision of gangrenous penile skin and skin grafting.

Conclusion

The study emphasizes the diversity of clinical presentations and the need for employing different surgical techniques to achieve the desired results.Key Words: Penile strangulation, Constricting objects, Penile amputation
