The canalis sinuosus is a neurovascular canal, a branch of nerve of infraorbital canal, through which the anterior superior alveolar nerve passes and then leans medially in course between the nasal cavity and the maxillary sinus, reaching the premaxilla in the canine and incisor region. The purpose of this article is to report a case with the presence of canalis sinuosus, in order to alert and guide professionals and discuss the morphology of this anatomical variation avoiding trans- and postsurgical disorders in dental implants...

Persistent left superior vena cava (LSVC) is a rare congenital anomaly. Its prevalence in the general population is 0.1 to 0.5%. LSVC is 5 times rarer when accompanied by an absence of the right superior vena cava (RSVC). We present the case of a 54-year-old man who carries a persistent LSVC without RSVC. Clinically, this patient presented a regular bradycardia at 40 per minute associated with a heart failure syndrome. The electrocardiogram diagnosed a complete atrioventricular block and transthoracic echocardiography showed dilated left heart cavities and a left ventricular ejection fraction of 50%...

Persistent left superior vena cava with absent right superior vena cava is a very rare venous anomaly and is known as isolated PLSVC. It is usually an asymptomatic anomaly and is mostly detected during difficult central venous access or pacemaker implantation, though it could also be associated with an increased incidence of congenital heart disease, arrhythmias, and conduction disturbances. Herein, we describe a dual-chamber pacemaker implantation in a patient with isolated PLSVC and sick sinus syndrome.

The posterior maxilla is challenged with postextraction alveolar bone resorption and pneumatization drive of the Schneiderian membrane that reduces the subantral distance. To overcome such anatomic obstacle a sinus augmentation procedure was introduced either via lateral or crestal approach depending on residual ridge height. The current study evaluated oxidized regenerated cellulose (ORC) as a grafting material versus osteon II by measuring bone gain and graft density, 24 weeks postoperatively. Twenty consecutive patients (24 cases) aged from 20 to 65 years were considered eligible after clinical and radiographic evaluation...

INTRODUCTION: One of the most frequently used method for scanning patients with indication for dental implantation in dentistry is cone beam computed tomography. Implantation, CBCT imaging and implant programme are inevitable when planning a successful replacement of lost teeth. CBCT offers exact information about available bone and its density, adjacent tooth roots, the place of mandibular canal and maxillary sinus and adjacent anatomical structure. AIM: The goal of this study is to estimate accuracy of measurements on CBCT images ofpatients who have implants of different producers and determine if there is any statistically significant correlation between four test groups regardless of the alloy of which implants are made...

Yellow nail syndrome (YNS) is characterized by yellowish nails, lymphedema, sinusitis, and pulmonary involvement and can be triggered by various underlying conditions, such as sinusitis or titanium exposure from an artificial joint or dental implant. Since YNS is potentially treatable, its timely diagnosis is important. The authors recently experienced a case of YNS in a patient who developed sinusitis, yellowish nails, bilateral edema of the extremities, and subclinical rheumatoid arthritis after the implantation of a cardiac pacemaker made from titanium...

This case series study demonstrates the possibility of successful implant rehabilitation without bone augmentation in the atrophic posterior maxilla with cystic lesion in the sinus. Sinus lift without bone graft using the lateral approach was performed. In one patient, the cyst was aspirated and simultaneous implantation under local anesthesia was performed, whereas the other cyst was removed under general anesthesia, and the sinus membrane was elevated in a second process, followed by implantation. In both cases, tapered 11...

Myocardial infarctions are frequently complicated by tachyarrhythmias, which commonly have wide QRS complexes (QRS duration > 120 milliseconds). Many published criteria exist to help differentiate between ventricular and supraventricular mechanisms. We present a case of a 61-year-old male with a history of hypertension, hyperlipidemia and coronary artery disease with prior stenting of the right coronary artery (RCA). He had been noncompliant with his antiplatelet medication and presented with cardiac arrest secondary to in-stent thrombosis...

Autogenous bone remains the gold standard for augmentation of the alveolar ridge in congenital hypodontia and appreciable post-traumatic deformity. This generally reflects the volume of material required for such defects and the osteogenic potential of the grafts. Morbidity at the donor site and success rates may lead to autogenous grafts being superseded by xenografts or alloplastic materials in the future, but we know of little evidence to confirm this. All patients having augmentation of the alveolar ridge or sinus lift to enable subsequent placement of implants between 01 January 2009 and 31 December 2016 were identified from a prospectively-gathered database held at the Queen Elizabeth Hospital, Birmingham...

Fracture-related infection (FRI) is a common and serious complication in trauma surgery. Accurately estimating the impact of this complication has been hampered by the lack of a clear definition. The absence of a working definition of FRI renders existing studies difficult to evaluate or compare. In order to address this issue, an expert group comprised of a number of scientific and medical organizations has been convened, with the support of the AO Foundation, in order to develop a consensus definition. The process that led to this proposed definition started with a systematic literature review, which revealed that the majority of randomized controlled trials in fracture care do not use a standardized definition of FRI...

Osteotomes have long been used in the formation of osteotomies for the placement of dental implants. Their ability to manipulate and compress existing bone without generating heat makes them particularly useful for expanding narrow ridges, elevating delicate sinus membrane, and increasing relative bone density around the osteotomy. Common concerns with these devices include the traumatic force communicated to the patient during use and difficulty controlling force vectors. A new type of osteotome has been developed that is designed to enable the clinician to eliminate the concerns found with traditional osteotomes yet it preserves the best qualities and functionality of this class of device...

BACKGROUND: Atrial fibrillation (AF) and left ventricular systolic dysfunction (LVSD) frequently co-exist despite adequate rate-control. Existing randomized studies of AF and LVSD of varying etiologies have demonstrated modest benefits with a rhythm control strategy. OBJECTIVE: To determine whether catheter ablation (CA) for AF could improve LVSD compared to medical rate-control (MRC) where the etiology of the LVSD was unexplained, apart from the presence of AF...
