Clinical Cases

Accidental implant displacement into the maxillary sinuses and accompanying complications are well documented in the literature. Two surgical approaches have been suggested to remove the displaced implants and to handle the related complications: an intraoral approach and the nasal endoscopy. The intraoral approach is preferred in cases of absence of local infection, ostium obstruction, and oroantral communication needing to be closed. The nasal approach, besides retrieval of displaced implants, allows the treatment of any associated pathology and reestablishment of the mucociliary clearance as well as the natural ventilation through the ostium. This article reports two clinical cases of implant displacement in the maxillary sinus treated with a nasal endoscopy through the middle meatal meatotomy. This article reports two clinical cases of implant displacement in the maxillary sinus treated with a nasal endoscopy through the middle meatal meatotomy. Implants accidentally displaced can be avoided by a proper exploration of the preoperative x-ray, selecting an appropriate treatment plan, and esteeming the surgical skills. The most appropriate approach to handle these complications is close cooperation between oral surgeons and otolaryngologists.

Introduction. Cementoblastoma is a rare and benign odontogenic mesenchymal tumor, often characterized by the formation of cementum-like tissue produced by neoplastic cementoblasts attached to or around the roots of a tooth.Case Report. 22-year-old male patient was referred to the Federal University of Paraná after occasional finding on a routine panoramic radiograph. Clinical examination suggested no alterations. Medical and family history presented no alterations as well. Computed tomographic (CT) showed the presence of a radiopaque area associated with the roots of the impacted third molar measuring 15 mm × 10 mm inside the left maxillary sinus. The treatment plan suggested was to surgically remove it under general anesthesia. An intraoral approach was conducted, using the Newmann incision from the superior left first molar to the retromolar area with anterior and posterior relaxant incisions. Using a Caldwell-Luc access next to the maxillary tuberosity region, the maxillary sinus was exposed and the calcified mass attached to the roots of the tooth was reached. Pathological mass removed was sent for histopathological investigation. Examination revealed dense, mineralized, cementum-like material and vascular soft tissue areas that consisted of cementoblasts. One-year follow-up shows no recurrence and absence of symptoms.

Abstract Background Surgical options for patients vary with age and comorbidities, advances in medical technology and patients’ wishes. This complexity can make it difficult for surgeons to determine appropriate treatment plans independently. At our institution, final decisions regarding treatment for patients are made at multidisciplinary meetings, termed High-Risk Conferences, led by the Patient Safety Committee. Methods In this retrospective study, we assessed the reasons for convening High-Risk Conferences, the final decisions made and treatment outcomes using conference records and patient medical records for conferences conducted at our institution from April 2010 to March 2018. Results A total of 410 High-Risk Conferences were conducted for 406 patients during the study period. The department with the most conferences was cardiovascular surgery (24%), and the reasons for convening conferences included the presence of severe comorbidities (51%), highly difficult surgeries (41%) and nonmedical/personal issues (8%). Treatment changes were made for 49 patients (12%), including surgical modifications for 20 patients and surgery cancellation for 29. The most common surgical modification was procedure reduction (16 patients); 4 deaths were reported. Follow-up was available for 21 patients for whom surgery was cancelled, with 11 deaths reported. Conclusions Given that some change to the treatment plan was made for 12% of the patients discussed at the High-Risk Conferences, we conclude that participants of these conferences did not always agree with the original surgical plan and that the multidisciplinary decision-making process of the conferences served to allow for modifications. Many of the modifications involved reductions in procedures to reflect a more conservative approach, which might have decreased perioperative mortality and the incidence of complications as well as unnecessary surgeries. High-risk patients have complex issues, and it is difficult to verify statistically whether outcomes are associated with changes in course of treatment. Nevertheless, these conferences might be useful from a patient safety perspective and minimize the potential for legal disputes.

Posterior Area

Oro-antral communication (OAC) acts as a pathway for bacteria between the maxillary sinus and oral cavity, and is a common complication after the removal of a dental implant or extraction of a tooth from the maxillary posterior area. In the case of an untreated OAC, oro-antral fistula develops and becomes epithelialized. We aimed to introduce a treatment for OAC closure via a sinus bone grafting procedure using bone tacks and a collagen membrane with an allograft. The procedure was performed by applying an absorbable membrane made in pouch form. This membrane acted as a barrier for closing the large sinus membrane perforation. Bone tacks were used to fix the membranes. Subsequently, the maxillary sinus was filled with the allograft, and the absorbable membrane was reapplied. Primary closure was achieved by performing a periosteum-releasing incision for a tension-free suture. After 6 months, sufficient bone dimensions were gained without any occurrence of maxillary sinusitis or recurrence of OAC. Additional bone grafts and implantation could be performed to rehabilitate the maxillary posterior area. We conclude that this technique might be a useful treatment for reconstructing the maxillary posterior area with simultaneous sinus bone graft and OAC closure.

The histopathologic diagnosis of nasal and paranasal sinus masses may be problematic. Traditionally, a biopsy through an external ethmoidectomy or Caldwell-Luc procedure has been required. The advent of nasal endoscopy provides an alternative method of obtaining tissue. The diagnostic evaluations of 57 cases of nasal or paranasal sinus masses, seen from 1985 through 1991, were reviewed. The use of nasal endoscopy in the diagnosis of nasal and paranasal sinus masses was associated with decreased morbidity as compared to more traditional approaches. Potential surgical approaches were not violated prior to definitive treatment. Representative cases will be presented illustrating changes in management by using nasal endoscopes.

Central Nervous System Depression

Introduction Insomnia is the most commonly reported sleep disorder and remains undertreated in many patients. New changes to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, have changed the way insomnia is diagnosed. In patients who suffer from insomnia, a number of available treatment options exist including both behavioral therapy and medications. Literature Review: First line therapy for insomnia should always include behavioral modifications such as sleep hygiene and insomnia-oriented cognitive behavioral therapy. In patients deemed to need pharmacotherapy, first line medications include nonbenzodiazepine hypnotics (i.e., z-drugs) and antidepressants depending on the patients’ needs and comorbidities. The risk of next day impairment, parasomnias, and central nervous system depression are some of the most feared side effects with z-drugs. Second line drug therapy includes melatonin and suvorexant. Several concerns exist for suvorexant similar to other insomnia medications, but melatonin remains one of the safest medication alternatives. Other medication options such as benzodiazepines, antihistamines, and antipsychotics should rarely be used because of weak effectiveness data or serious safety concerns. Discussion The most appropriate treatment plan needs to be tailored to meet the needs of individual patients. Many patient factors (e.g., age, other comorbidities, specific problems with sleep) need to be considered before prescribing drug therapy for patients suffering from insomnia. Medications with the best evidence and fewest safety concerns should be prioritized when clinicians work with patients to determine the most appropriate treatment plan. Conclusions Nondrug treatment should be the emphasis for managing insomnia, but several options exist for patients needing multimodal therapy to improve their symptoms and maximize their quality of life. Z-drugs and antidepressants are first line medications options, but other options may be considered when tailored to individual patients. Medications should only be used intermittently and short term until nondrug treatments help to change a patient’s sleep routine.

ABSTRACT Purpose: We developed an integrated framework that employs a full Monte Carlo (MC) model for treatment-plan simulations of a passive double-scattering proton system. Materials and Methods: We have previously validated a virtual machine source model for full MC proton-dose calculations by comparing the percentage of depth-dose curves, spread-out Bragg peaks, and lateral profiles against measured commissioning data. This study further expanded our previous work by developing an integrate framework that facilitates its clinical use. Specifically, we have (1) constructed patient-specific applicator and compensator numerically from the plan data and incorporated them into the beamline, (2) created the patient anatomy from the computed tomography image and established the transformation between patient and machine coordinate systems, and (3) developed a graphical user interface to ease the whole process from importing the treatment plan in the Digital Imaging and Communications in Medicine format to parallelization of the MC calculations. End-to-end tests were performed to validate the functionality, and 3 clinical cases were used to demonstrate clinical utility of the framework. Results: The end-to-end tests demonstrated that the framework functioned correctly for all tested functionality. Comparisons between the treatment planning system calculations and MC results in 3 clinical cases revealed large dose difference up to 17%, especially in the beam penumbra and near the end of beam range. The discrepancy likely originates from a variety of sources, such as the dose algorithms, modeling of the beamline, and the dose metric. The agreement for other regions was acceptable. Conclusion: An integrated framework was developed for full MC simulations of double-scattering proton therapy. It can be a valuable tool for dose verification and plan evaluation.

Purpose: To commission MCsquare (a multi-cores CPU-based dose calculation engine) for pencil beam scanning (PBS) proton therapy, integrate it into RayStation treatment plan system (TPS) to create a dedicated platform for fast independent dose verification. Method: A MCsquare-based independent dose verification platform (MC2InRS) was developed to realize automatic dose re-calculation for clinical use, including data preparation, dose calculation, 2D/3D gamma analysis. MCsquare was commissioned based on in-air lateral dose profiles, integrated depth dose, and the absolute dose of different beam energies for Proteus®ONE. MC2InRS was validated with measurement data using various targets and depths in a water phantom. This study also investigated 15 clinical cases to demonstrate the feasibility and effectiveness of MC2InRS platform in clinic practice. Results: Between simulation and measurement, the distal range differences at 80% (R80) and 20% (R20) dose levels for each energy were below 0.05 mm, and 0.1 mm, respectively, and the absolute dose differences were below 0.5%. 29 out of 36 QA planes reached a 100% gamma passing rate (GPR) for 2%/2mm criteria, and a minimum of 98.3% gamma was obtained in water phantom between simulation and measurement. For the 15 clinical cases investigated, the average 2D GPR (2%/2mm) was 95.4%, 99.3% for MCsquare vs. measurement, MCsquare vs. TPS, respectively. The average 3D GPR (2%/2mm) was 98.9%, 95.3% for MCsquare vs. TPS in water, and computed tomography (CT), respectively. Conclusion: MC2InRS, a fast, independent dose verification platform, has been developed to perform dose verification with high accuracy and efficiency for Pencil Bream Scanning (PBS). Its potential to be applied in routine clinical practice has also been discussed.

Background. Hemimaxillectomy of acquired palatal defects may predispose the patient to hypernasal speech, leakage of fluids into the nasal cavity, impaired masticatory function, and swallowing difficulties leading to a detrimental impact on the quality of life. Sequentially, it can also affect individual character and trust in social life, leading to social phobia and anxiety. This article presents prosthodontic management of a young male patient with deformation of the entire right half of the face due to surgical removal of odontogenic myxoma. It describes a method where the clinician utilized a simple, noninvasive, and cost-effective technique to cut the weight of the obturator and to attain aesthetics, utilizing a detachable lip and cheek plumper. Case Presentation. A 19-year-old male attended the Prosthodontic Clinics at Faculty of Dentistry, the University of Khartoum, eight months after the surgical removal of a tumor. The chief complaint was difficulty eating or drinking. Furthermore, he dropped out of school because of his facial deformity and his indistinct voice. Medical and dental history revealed surgical resection of the entire right half of the maxillary alveolar bone due to myxoma. Intraoral examination revealed a well-healed surgical defect in the maxillary right buccal vestibule creating an oroantral communication. A treatment plan was formulated, keeping the patient’s demand in mind. The decision was made to treat the patient with a maxillary obturator that would gain its support from the remaining teeth and tissues with a detachable cheek and lip plumper. The use of dental magnets as a means of attachment was elected. Conclusion. This article has described a simple, noninvasive, and cost-effective method to improve facial appearance in patients with hollow faces. The plumper prosthesis successfully improved the patient’s appearance to the extent that comfort and function would permit and encourage self-esteem.

The Continuum

Homecare is an important component of the continuum of care as it provides the potential to improve quality of life and quality of healthcare delivery while containing costs. Personal Health Record (PHR) systems are intended to reach patients outside of care settings and influence their behaviors thus allowing for more effective homecare services. To this end, these systems need to evolve well beyond providing a consolidated patient record, in ways that make it more widely applicable and valuable to health systems. The development of applications on top of PHR systems can allow them to function as a platform for both patients and healthcare professionals to exchange information and interact with the health system. This paper presents a prototype PHR-based system that aims at supporting chronic disease management at any point of care or decision making through familiar environments such as Google’s Android. In particular, it assists healthcare professionals in assessing an individual’s condition and in forming the appropriate treatment plan for him/her while it provides individuals with step-to-step guidance to their treatment plans.
