Refined Technique

Sacrifice of the inferior alveolar nerve (IAN) during resection of the mandible is taken as a rule. In 1987, Jensen and Nock described a technique that permitted placement of dental implants in the atrophied mandibular alveolar ridge that lacked sufficient vertical height superior to the mandibular canal. This technique was used by some authors to preserve continuity of the IAN during resection of the mandible in patients with benign tumors. The described techniques are traumatic, time-consuming, and not precise. We propose a new refined technique of preservation of IAN with use of a guide to approach mandibular canal, cutting guides with a slot for a relocated IAN, and a new approach to positioning of the fixating screws. We assessed the effectiveness of this new technique with use of an electro-odontometer. In 21 cases, we demonstrated a refined approach to preservation of the IAN. In 7 patients (33%), the IAN was preserved on one side and in 14 patients (67%), on both sides. Sensation in the lower lip was restored in 18 patients (86%). These patients generally recovered sensation within 22 days postoperatively. This proposed technique makes preservation of IAN easier, faster, less traumatic, and more predictable. In this article, we describe criteria for the patients with cancer of oral mucosa to be admitted for this procedure. Restored sensation in the lower lip of the patients who have undergone resection of the mandible significantly improves their quality of life.

The most common clinical symptom in dentistry is pain. Doctors-dentists of practical health care have to face symptoms that doctors-forensic experts regard as a defect or neurological complication after dental treatment. Quite often there is acute toxic-traumatic neuropathy of the lower alveolar and chin nerve, which occurs when a filling material enters the mandibular canal during treatment of pulpitis or periodontitis of the premolars of the lower jaw [1-3]. During the filling of the canals, the patient has a very intense acute pain in the area of the lower jaw with numbness of the lower lip and chin. In connection with the wide spread and availability of implantological dental care to the population, neuropathies of traumatic genesis occur, the causes of which are mistakes in the setting of implants. One of the earliest manifestations of the above complications is a painful symptom leading to sleep disruption, the inability to fully fulfill their professional duties, fully eat and communicate, that is, to reduce the quality of life of patients. Using the short form (SF-36) as a questionnaire, 86 patients of dental clinics, who according to the medical documentation, had complications after performing dental interventions with different degrees of pain, found that the quality of life in general, with an increase in pain up to 100%, decreases to an average of 60%.

IntroductionPatients with cancer undergoing surgery often suffer from reduced quality of life and various forms of distress. Untreated distress can negatively affect coping resources as well as surgical and oncological outcomes. A virtual reality-based stress reduction intervention may increase quality of life and well-being and reduce distress in the perioperative phase for patients with cancer. This pilot trial aims to explore the feasibility of the proposed intervention, assess patient acceptability and obtain estimates of effect to provide data for sample size calculations.Methods and analysisPatients with colorectal cancer and liver metastasis undergoing elective surgery will be recruited for this single-centre, randomised pilot trial with a three-arm design. A total of 54 participants will be randomised at 1:1:1 ratio to one of two intervention groups or a control receiving standard treatment. Those randomised to an intervention group will either receive perioperative virtual reality-based stress reduction exercises twice daily or listen to classical music twice daily. Primary feasibility outcomes are number and proportions of participants recruited, screened, consented and randomised. Furthermore, adherence to the intervention, compliance with the completion of the quality of life questionnaires and feasibility of implementing the trial procedures will be assessed. Secondary clinical outcomes are measurements of the effectiveness of the interventions to inform sample size calculations.Ethics and disseminationThe study protocol, the patient information and the informed consent form have been approved by the ethics committee of the Ludwigs-Maximilians-University, Munich, Germany (Reference Number: 19–915). Study findings will be submitted for publication in peer-reviewed journals.Trial registration numberDRKS00020909.

This article reports on the journey of a child with an inoperable hypothalamic-origin pilocytic astrocytoma causing hydrocephalus, which was refractory to treatment with shunts, and required a new approach. With multidisciplinary support, excellent nursing care and parental education, the child's hydrocephalus was managed long term in the community with bilateral long-tunnelled external ventricular drains (LTEVDs). This article describes the patient's journey and highlights the treatment protocols that were created to achieve this feat. Despite the difficulties in initially setting up these protocols, they proved successful and thus the team managing the patient proposed that LTEVDs are a viable treatment option for children with hydrocephalus in the context of inoperable tumours to help maximise quality of life.

Abstract Background The purpose of this study was to analyze medium-to-long-term implant success and survival rates, and lower lip sensory disturbance after placement of dental implants with simultaneous inferior alveolar nerve (IAN) repositioning. Methods Fifteen patients (3 men, 12 women) treated in two centers were included in this retrospective study. The ages of the participants ranged from 19 to 68. A total of 48 dental implants were placed in 23 posterior mandibular segments simultaneously with IAN transposition or lateralization. The residual bone above the IAN ranged from 0.5 to 7.0 mm. Crestal bone changes were measured using cone beam computed tomography (CBCT) images. Disturbance of the IAN was evaluated subjectively using a modified questionnaire. Results The healing process was uneventful in fourteen patients. In one patient, spontaneous fracture of the operated mandible occurred on tenth day after the surgery. The implant in the fracture line was removed at the time of open reduction and fixation. One more implant was lost after 5 years of loading. Therefore, the overall dental implant survival rate was 95.8%, whereas all implants in function were judged as successful after a follow-up period of 1 to 10 years. Transient neurosensory disturbances (ND) were observed in all patients who underwent IAN lateralization and IAN transposition. At follow-up times of 3 years, 5 years, and 10 years, weak hypoesthesia remained in two subjects treated with IAN transposition. None of the patients developed neuropathic pain after the procedure. Conclusions Within the limitations of this study, we conclude that reconstruction of severely resorbed mandibles with dental implants in conjunction with IAN repositioning is an effective and reliable technique. Although neurosensory disturbances are the most common complication after surgery, they tend to resolve over time. Advanced surgical skills are required to perform this technique.

Abstract This paper presents a new approach to discover the effect of depth water for underwater visible light communications (UVLC). The quality of the optical link was investigated with varying water depth under coastal water types. The performance of the UVLC with multiple input–multiple output (MIMO) techniques was examined in terms of bit error rate (BER) and data rate. The theoretical result explains that there is a good performance for UVLC system under coastal water.

The Traveling Tournament Problem (TTP) is concerned with finding a double round-robin tournament schedule that minimizes the total distances traveled by the teams. It has attracted significant interest recently since a favorable TTP schedule can result in significant savings for the league. This paper proposes an original evolutionary algorithm for TTP. We first propose a quick and effective constructive algorithm to construct a Double Round Robin Tournament (DRRT) schedule with low travel cost. We then describe an enhanced genetic algorithm with a new crossover operator to improve the travel cost of the generated schedules. A new heuristic for ordering efficiently the scheduled rounds is also proposed. The latter leads to significant enhancement in the quality of the schedules. The overall method is evaluated on publicly available standard benchmarks and compared with other techniques for TTP and UTTP (Unconstrained Traveling Tournament Problem). The computational experiment shows that the proposed approach could build very good solutions comparable to other state-of-the-art approaches or better than the current best solutions on UTTP. Further, our method provides new valuable solutions to some unsolved UTTP instances and outperforms prior methods for all US National League (NL) instances.
