Emergency physician accuracy using ultrasonography to diagnose lateral malleolar fracture

Objective

Many studies in the literature related to the investigation of the sensitivity and specificity of ultrasound examinations in lateral malleolar fractures is limited. The aim of this study is to investigate the sensitivity and specificity of ultrasound examinations performed by emergency physicians in fractures who are presented to the emergency department with blunt lateral malleolar trauma.

Orthognathic surgery of a patient with oligodontia: alternative technique for intermaxillary fixation

ABSTRACT: Oligodontia may cause various problems during orthognathic surgery because it may be difficult to fix the surgical guide splints. The aim of this clinical report was to present an alternative technique for intermaxillary fixation of a patient with oligodontia and facial deformity. A 20-year-old male patient, whose 8 maxillary and 11 mandibular teeth were congenitally missing, was treated using bimaxillary orthognathic surgery. Before the surgical approach, fixed mandibular prosthesis containing pins on the vestibule sides of the crowns was constructed to provide anchorage for intermaxillary splint and to achieve occlusal stability and vertical dimension during the surgery. This prosthesis was also used to hang intraoral elastics during the postoperative orthodontic treatment. At the end of treatment, these pins were cut, composite restoration material was applied to camouflage the places of the pins, and the patient continued to use this prosthesis. The patient gained an appropriate facial aesthetics and oral function using multidisciplinary approach.     

A case of extramedullary plasmacytoma in the sphenoid sinus with unilateral loss of vision

Extramedullary plasmacytomas are localized tumours formed of monoclonal plasma cells in an extra-skeletal area. They constitute approximately 3% of all neoplasms originating from plasma cells. They generally display a destructive course. When the literature in English was reviewed, only 19 cases with the primary disease localized in the sphenoid sinus were found. We present the case of a 50-year-old male patient who presented with gradually increasing visual loss over 6 weeks, whose radiological tests revealed a formation of mass in the sphenoid sinus pressing against the optic nerve and internal carotid artery. A biopsy obtained by endoscopic sinus surgery was reported to be a plasmacytoma. A diagnosis of extramedullary plasmacytoma was made after investigations for other neoplastic plasma cell conditions proved negative.Extramedullary plasmacytomas were assessed by reviewing the literature.     

Pulmonary involvement in sea-blue histiocytosis

Sea-blue histiocytosis is one of the six types of Niemann-Pick disease. It is characterized by childhood onset of hepatosplenomegaly, lack of neurological involvement and diminished sphingomyelinase activity. Pulmonary system is rarely involved sea-blue histiocytosis. In this paper, we present a 39-years-old male who had previously diagnosed as sea-blue histiocytosis at the age of 15. He was admitted to our clinic due to productive cough, hemoptysis, fever and weight loss. His symptoms did not resolve with the antibiotic treatment and further investigations revealed pulmonary involvement of sea-blue histiocytosis. After diagnostic bronchoalveolar lavage, his symptoms were improved, interestingly. This rare entity was discussed with literature survey.     

Single-stage aortic valve-sparing root replacement and extra-anatomic bypass for aortic arch interruption in an adult

We describe the treatment of an extremely rare case of interrupted aortic arch, annuloaortic ectasia, and aortic regurgitation in a 34-year-old man who presented with dyspnea and palpitation. We performed a single-stage operation involving aortic root reconstruction and valve repair with concomitant extra-anatomic bypass from the ascending to the descending aorta with a Dacron tube graft. The patient made a full recovery. To the best of our knowledge, this is the first such report in the English medical literature.     

Axillary Lymph Node Status in Multicentric Breast Tumors and Breast Tumors with Nipple Involvement

Background

Axillary lymph node dissection plays an important role in breast cancer management in terms of staging, prediction of prognosis, determination of adjuvant therapy, and local control of the primary tumor. The objective of this study was to evaluate the axillary lymph node involvement in multicentric breast tumors and breast tumors with nipple involvement in comparison with unifocal tumors.

Patients and Methods

We reviewed the records of 267 patients with stage I or IIA disease. The rates of axillary lymph node metastasis (ALNM) in patients with unifocal tumors, multicentric tumors, or nipple involvement were compared.

Results

209 (78%) patients had unifocal tumors, 24 (8%) had multicentric tumors, and 34 (12%) had nipple involvement. The incidence of ALNM was 9.76% in patients with unifocal tumors, 24.84% in patients with multicentric tumors, and 36.71% in patients with nipple involvement. Hence, the incidence of ALNM was significantly higher in patients with nipple involvement or multicentric tumors than in patients with unifocal tumors.

Conclusion

Our data suggest that compared to unifocal tumors, breast tumors with nipple involvement or multiple foci show a significantly higher incidence of ALNM which is a predictor of a poor prognosis.     

The accuracy of bedside ultrasonography as a diagnostic tool for the fifth metatarsal fractures

Objectives

Musculoskeletal ultrasonography is a technique that is becoming more popular in diagnosing injuries of emergency department (ED) patients especially for the diagnosis of fractures. In this study, we determined the reliability of ultrasonography for the diagnosis of fractures of the fifth metatarsal.

Method

This is a prospective blind study. Patients over 14 years old who were admitted to the ED with acute foot injury and who had tenderness on the fifth metatarsal were consecutively enrolled into the study. A bedside ultrasonography exam was performed by an emergency physician, and antero-posterior and oblique views were obtained. X-rays were blindly evaluated by an orthopedic surgeon and were considered to be the gold-standard for diagnosing fractures. In patients with noncomminuted fractures, bone displacement was measured by both radiologically and sonographically.

Results

Eighty-four patients were included in this study. Their mean age was 36.0, and 42.9% were male. Fractures were diagnosed by both x-ray and ultrasonography in 33 patients. In one patient, the x-ray was positive for fracture, while ultrasonography yielded a negative result. For the fractures of fifth metatarsal, the diagnostic sensitivity of ultrasonography was 97.1%, the specificity was 100%, the positive likelihood ratio was infinity, the negative likelihood ratio was 0.03. Mean displacement was 1.2 ± 0.7 mm with x-ray and 1.8 ± 1.5 mm with ultrasonography. The intraclass correlation coefficient of displacement measured by x-ray and ultrasonography was κ: 0.388.

Conclusion

Ultrasonography is a reliable diagnostic tool for acute fifth metatarsal fractures.
