Nd: YAG Laser in Oral Cavity Cancer Report of 200 Cases — Minimum Follow up of one Year

Peripheral Ameloblastoma (PA) is the rarest variant of ameloblastoma. It differs from the other subtypes of ameloblastoma in its localization: it arises in the soft tissues of the oral cavity coating the tooth bearing bones. Generally, it manifests nonaggressive behavior and it can be treated with complete removal by local conservative excision. In this study we report a case of PA of the maxilla in a 78-year-old female patient and we describe the four different histopathological patterns revealed by histological examination. After local excision and diagnosis, we planned a long term follow-up: in one year no recurrence had been reported. The choice of treatment is illustrated in Discussion.

Pyogenic granuloma is a benign, localized mass of exuberant granulation tissue produced in response to various stimuli. It is inflammatory hyperplasia of oral cavity commonly seen on gingival area and rarely on other parts of oral cavity such as lips, tongue, palate and buccal mucosa. It is seen predominantly in 2nd to 3rd decade of life in young females. Clinically manifesting as small red erythematous exophytic lesion, it must be biopsied to rule out other serious conditions. This article aims to present three cases of extra gingival pyogenic granulomas occurring in rare sites such as buccal mucosa, anterior hard palate and alveolar mucosa of completely edentulous ridge in maxilla. Pyogenic granuloma on buccal mucosa and anterior hard palate were seen in female patients with age of 40 years and 34 years respectively and pyogenic granuloma on alveolar mucosa of edentulous ridge in maxilla was noted in 70 years old male patient. Surgical excision was performed for all the lesion and follow up of one year did not show any recurrence. Please add little description of patient + treatment + followup results.

Abstract Purpose Herein, we elucidated the effect of anterior capsule polishing (ACP) during cataract surgery on the rate of neodymium: YAG (Nd: YAG) laser capsulotomy in multifocal intraocular lens (MIOL). Methods We extracted the medical records of patients who underwent phacoemulsification with MIOL between May 2016 and April 2017 from the files of the patients, and the follow-ups of fewer than 3 years were excluded. The participants were divided into the ACP group and the non- ACP group based on whether the anterior capsule was polished. The primary outcome was whether to perform Nd: YAG capsulotomy during the follow-up. We analyzed the time from IOL implantation to Nd: YAG laser capsulotomy using the Kaplan-Meier survival curves. Results The ACP group comprised 70 eyes and non-ACP group, 60 eyes. One year postoperatively, 7.14% of the eyes in the ACP group and 8.33% in the non-ACP group required Nd: YAG laser capsulotomy (P > 0.99). After 2 years, it was 24.29% and 18.33%, respectively (P = 0.52). After 3 years, it was 30.0% and 28.33% respectively (P = 0.85). There was no distinct difference in the probability for Nd: YAG laser between the ACP group and the non-ACP group evaluated using Kaplan-Meier survival curves (P = 0.81). Patients with implantation of diffractive MIOL (AT LISA tri 839MP) had a high probability of requiring Nd: YAG laser capsulotomy. Conclusion Polishing the anterior capsule had no remarkable effect on reducing the rate of Nd: YAG laser capsulotomy after phacoemulsification in MIOL.

The veterinarian doctor has to be prepared to help various kind of species. Our team had to perform dental treatment for a five years old European red tail deer. The deer was eating with difficulty. Even thou it was a hot summertime, the hind presented late shedding. Her calm and kind behaviour changed into an aggressive one. She was biting cold, metal objects, obviously to calm her dental pain. Our approach aimed to re-establish the biological and physiological balance of the oral cavity. A thorough general exam was performed for differential diagnosis. Oral examination revealed an aggressive periodontal disease. Surgical extractions were the only possible treatment. One year follow up is good, changing the prognosis from a reserved one into very good.

<p class="abstract">Management of head and neck cancer defects has been challenging owing to the complexity of the created defects. Various local and regional flaps to free flaps have been described in the reconstruction of cancer defects, each of them having it’s own merits and limitations, therefore none of them appears as an ideal one. A Submandibular gland flap (SMGF) technique has emerged as a versatile flap having advantages of a regional and a free flap. In this study, eleven patients (four tongue, six buccal mucosa defects and one retromolar trigone defect) underwent reconstruction of oral cavity cancer defects with SMGF. The outcomes of the SMGF were evaluated in terms of the ease of harvest, functional outcome, and postoperative complications. The mean defect size and the flap dimensions were 4.4×3.9 cm and 3.6×3.3 cm respectively. One patient suffered wound infection resulting in partial flap necrosis with wound dehiscence. In the follow-up period one patient developed contra nodal recurrence and another patient developed a second primary on the contralateral base of the tongue. This study showed that SMGF is an excellent flap for the reconstruction of oral cavity cancer defects because of its reliability, versatility and its relative ease of application.</p>

Patient Mix

The objectives of this study were to investigate potential relationships between pretreatment patient-mix characteristics, treatment modalities, and costs generated during the pretreatment work-up, treatment, and 1-year follow-up periods for patients with oral cavity cancer (OCC). Another objective was to identify potential areas for cost reduction and improved resource allocation in the management of OCC patients. Using a retrospective cohort of 73 patients with OCC, pretreatment patient-mix characteristics and treatment modalities were evaluated in relation to university-based charges incurred during the pretreatment evaluation, treatment, and 1 -year follow-up periods. Simple regression and stepwise multiple regression analyses were used to develop predictive models for cost based on independent variables, including age, AJCC TNM clinical stage, smoking history, American Society of Anesthesiologists (ASA) class, comorbidity as defined by the Kaplan-Feinstein grade and treatment modality. The dependent measurements included all physician, office, and hospital charges incurred at the University of Iowa Hospitals and Clinics during the pretreatment evaluation, treatment, and follow-up periods, as well as the total pretreatment through 1-year follow-up management costs. Independent variables that were identified as being significantly associated with treatment costs included T classification, N classification, TNM stage, unimodality versus multimodality treatment, and the Kaplan-Feinstein comorbidity grade. Age, smoking status, and ASA class were not significantly associated with costs. The majority of the OCC management costs were incurred during the treatment period. The most substantial decreases in management costs for OCC will be realized through measures that allow identification and treatment of disease at an early stage, in which single-modality treatment may effectively be used. Resource allocation for OCC should support the investigation of measures through which the diagnosis and treatment of OCC at the earliest possible stage is facilitated. The presence of comorbid illness is a significant component in the determination of management costs for OCC and should be included in analyses of resource allocation for OCC. The singular diagnosis of OCC encompasses a wide range of patient illness severity, and diagnosis-related reimbursement schemes for OCC treatment should optimally differentiate between early and advanced stage disease.

Abstract Background: Pyogenic granuloma is a common, benign, acquired vascular lesion involving the skin and mucous membrane. It occurs in exposed areas, such as oral and maxillofacial regions, hands and feet, which usually have aesthetic affections on the patients’ appearance. Although pyogenic granuloma is treatable by a variety of treatments, they bear defects such as high recurrence rate, multiple therapies, leaving obvious scars, hyperpigmentation, or skin atrophy. In this study, we treat pyogenic granuloma patients with both ultrapulsed CO2 laser and long-pulsed Nd: YAG laser, in order to achieve ideal effects. Methods: 20 participants with pyogenic granuloma of the oral and maxillofacial region were treated with ultrapulsed CO2 laser and long-pulsed Nd: YAG laser, reexamined one month later, and followed up for one year. Clinical characteristics and treatment effects were recorded and examined.Results: The 20 participants were all cured by one treatment with a cure rate of 100%. None of the patients had scar or recurrence during12 months of follow-up. Conclusions: Ultrapulsed CO2 laser combined with long-pulsed Nd: YAG laser is a safe and cosmetically effective solution for pyogenic granuloma of the oral and maxillofacial region.Trial registration: This research is a retrospective study.

The Impact

The optimal follow-up protocol after treatment of oral cavity cancer patients is still debatable. We aimed to investigate the impact of frequency of different imaging studies and follow-up visits on the survival of oral cavity cancer patients. The current study retrospectively reviewed oral cavity cancer patients who underwent surgical intervention in our hospital. Basic demographic data, tumor-related features, treatment modalities, imaging studies, and clinic visits were recorded. Cox proportional hazard model was used to examine the influence of variables on the survival of oral cavity cancer patients. In total, 741 patients with newly diagnosed oral cavity cancer were included in the final analysis. Overall, the frequency of imaging studies was not associated with survival in the multivariate analysis, except PET scan (hazard ratio [HR]: 5.30, 95% confidence interval [CI]: 3.57–7.86). However, in late-stage and elder patients, frequent head and neck CT/MRI scan was associated with a better prognosis (HR: 0.55, 95% CI: 0.36–0.84; HR: 0.52, 95% CI: 0.30–0.91, respectively). In conclusion, precision medicine is a global trend nowadays. Different subgroups may need different follow-up protocols. Further prospective study is warranted to clarify the relationship between frequency of image studies and survival of oral cavity cancer patients.
