Cryptorchidism, as a singular pathology or associated with other dysgenesis syndromes, is one of the main factors of risk for the development of the testicular tumors. Although there are a great number of cases of undescended testicles that are diagnosed and treated during the first 6-12 months of life, there are rare cases of adults who are undiagnosed and untreated from this anomaly, which can present a high risk of malignancy. In this study we present the case of a 36-year-old patient, diagnosed at puberty with left cryptorchidism, untreated, who also hadevidenced a large intraabdominal tumoral mass associated with it. The tumoral mass had its origin in the undescended left testicle. Surgical excision of the tumor and retroperitoneal lymphadenectomy was performed. The histological result revealed embryonal carcinoma, without lymphnode metastasis. Adult patients with untreated cryptorchidism should be thoroughly investigated, as they have a high risk of developing testicular cancer.Lichen planus is a common chronic inflammatory condition that affects skin and mucous membranes. Management is often delayed because of patient embarrassment or misdiagnosis by the clinician. Early recognition and treatment is essential to reduce the morbidity of this condition. We present a 58-year-old woman diagnosed with generalized hypertrophic lichen planus, a rare event, reported to occur usually on lower extremities, but found to be generalized in our patient, requiring excision of symptomatic lesions. We suggest a multidisciplinary approach to allay the anxiety and symptoms of these patients and to improve the quality of life and clinical outcomes.Background and aims Considering nowadays trend among dentists to install a radiology laboratory beside their current practice, we proposed to investigate the aspect of financial efficiency related to such investment. Methods We evaluate two existing options simple investment, consisting of intra-oral equipment and accessories, or investment in a radiology center that includes panoramic and CBCT equipment. The initial investment includes equipment acquisition, fitting out of the location, radiology accreditation and other miscellaneous expenses. Costs were estimated based on current quotations on the specific market available in Romania. We also described a financial model to estimate the financial risk. Results The analysis was made under the assumptions that the laboratory is operated by the dentist who made the investment in the form of a legal person and paying corporate tax like all Romanian entities. The analysis took into account current fees for different types of X-rays, usual expenses of such a laboratory, and describes the approach to this analysis, starting with the initial investment estimation and forecast of revenues and expenses. Based on these projections and assessment of the working capital, we have built the cash flows forecast. Following a risk analysis we could assess the financial efficiency of the two investment alternatives. Conclusions Our study reveals that the radiology center represents a more profitable investment due to the higher economic return rate.Objectives To identify the potential risk factors for the occurrence of osteoradionecrosis (ORN) of the jaws among patients who have been treated with radiotherapy for head and neck malignancy. Methods The study comprised of 231 patients treated with radiotherapy for head and neck malignancy at a tertiary referral center. The following details were recorded for each patient age, gender, histopathological diagnosis, clinical staging, tumor site, treatment modality, radiation dose, radiation field, number of fractions, type of accelerator used, radiation area and duration of follow-up. Patient’s tobacco, alcohol habit history, and history of extraction of teeth before/during/after radiotherapy were also noted. Results Thirteen patients had osteoradionecrosis (frequency 5.62%). Among the radiotherapy variables assessed, increased radiation area was found to be significantly associated with the occurrence of osteoradionecrosis. Among the 13 ORN cases, 10 (76.9%) had a history of tobacco consumption, 8 (61.5%) had a time interval between radiotherapy and occurrence of ORN of less than 1-year duration. Conclusions We found a low cumulative incidence of osteoradionecrosis and a tendency to occur within a year of starting radiotherapy. Patients of older age, those with a prior tobacco habit may be considered more liable to develop osteoradionecrosis. A larger radiation field may also put patients at hazard for developing osteoradionecrosis.Background and aims Blue grass appliance, also known as habit correction roller has gained universal attention and acceptance to correct thumb sucking habit. The present study utilizes the modified bluegrass appliance that was fabricated with an inexpensive acrylic roller to lower the cost of treatment and make it more affordable for the patients in developing countries. The purpose of this study was to evaluate the efficacy of the modified bluegrass appliance in cessation of thumb-sucking habit. Methods Forty children aged 4-14 years visiting our department for the treatment of thumb sucking habit were selected. A modified bluegrass appliance having an acrylic roller was used along with the positive reinforcement. The patients were followed-up after two weeks of appliance placement and then monthly for twelve months. The various factors like need of reinsertion, discomfort caused due to improper placement or distortion, and/or breakages of the appliance following insertion were evaluated. The cessation of th patients and very much successful in eliminating the habit within a short period of time without any complications.Introduction One of the principle factors for the success of implant supported/retained overdentures (IOs) is the manner in which the stresses are transferred to the surrounding bone. Hence, the aim of the present study is to compare the stress induced in the mandible around IOs, using two different attachment systems, locator and telescopic. Methods 3D finite element models were prepared using Pro/ENGINEER or PTC Creo to simulate 4 clinical situations IOs using two different attachment systems, locator and telescopic, with and without splinting. A vertical compressive load of 35N was directed toward the central fossa in the molar region of each overdenture. Non-linear static contact analysis was carried out to determine the stress distribution in various components of IOs. Samuraciclib order Then, the models were analyzed by a finite element program ABAQUS, and displayed using Von Mises stress patterns. Results The contact stress values developed on the implant and attachment components were lower with locator attachment, in both splinted and non-splinted models.
