Article Synopsis
  • The study investigates the risk of severe oral mucositis (SOM) in patients undergoing graft-versus-host disease (GVHD) prophylaxis during hematopoietic cell transplantation, focusing on methotrexate (MTX) versus other agents.
  • Using a thorough analysis of published studies, researchers found that patients on MTX or MTX-inclusive regimens had a significantly higher risk of SOM compared to those receiving non-MTX treatments.
  • The findings suggest that alternatives like mycophenolate mofetil (MMF), folinic acid (FA), and lower doses of MTX may reduce the severity of mucositis, highlighting a need for more randomized controlled trials (RCTs) on MTX to optimize patient

Salivary stones are hardened, stony calcifications that primarily develop in the drainage duct of a salivary gland. They can lead to obstruction of the saliva flow, resulting in swelling and pain. Since the aetiology of salivary stones remains largely unclear, this was further investigated in this PhD study.

Precancerous cells in the oral cavity may appear as oral potentially malignant disorders, but they may also present as dysplasia without visual manifestation in tumor-adjacent tissue. As it is currently not possible to prevent the malignant transformation of these oral precancers, new treatments are urgently awaited. Here, we generated precancer culture models using a previously established method for the generation of oral keratinocyte cultures and incorporated CRISPR/Cas9 editing.

Background: Resilience is the capacity of an animal to be minimally affected by disturbances or to rapidly return to its initial state before exposure to a disturbance. Resilient livestock are desired because of their improved health and increased economic profit. Genetic improvement of resilience may also lead to trade-offs with production traits.

Objectives: Evaluate whether regular follow-up of oral leukoplakia (OL) resulted in early detection of malignant transformation (MT).

Method: Two hundred and twenty-two consecutive patients with OL (147 females, 75 males); median follow-up period of 64 months (range: 12-300). Three groups were distinguished: group A (n = 92) follow-up at the hospital; group B (n = 84) follow-up by their dentist; group C (n = 46) lost to follow-up.

Objective: Oral leukoplakia is the most common oral potentially malignant disorder. Malignant transformation of oral leukoplakia occurs at an annual rate of 1%-7%. WHO-defined classic epithelial dysplasia is an important predictor of malignant transformation of oral leukoplakia, but we have previously shown in a proof of concept study that prediction improves by incorporation of an architectural pattern of dysplasia, also coined as differentiated dysplasia.

Background: Urinary and sexual dysfunction after radical prostatectomy remains a major cause of morbidity, despite widespread availability of pharmacological and rehabilitative treatments. Smoking is a modifiable risk factor known to correlate with erectile and urinary dysfunction and we hypothesise that smoking cessation may improve post-prostatectomy urinary and sexual function recovery. Our objective is to systematically evaluate literature describing the association of smoking status with urinary and sexual function in men following radical prostatectomy.

A 12-year-old boy was referred with a painless swelling of the labial gingiva. The swelling was caused by the antihypertensive amlodipine, which he used because of arterial hypertension due to a chronic kidney disease. The treatment consisted of discontinuation of the causative drug after which the swelling of the gingiva slowly subsided.

Tyrosine kinase receptors (TKR) coordinate a variety of pathological processes in head and neck squamous cell carcinoma (HNSCC), and eventually play a role in patient outcomes. In this review, the role of Eph receptors in HNSCC progression and the possibility of targeting these receptors are illustrated. All relevant studies were identified through a comprehensive search of four electronic databases, including PubMed, Scopus, web of science, and Embase till August 2022.

Ulceration is a common presenting sign of a wide spectrum of diseases of the oral cavity involving many etiologic factors, such as trauma, infection, neoplasms, medication, and immune related disorders, ranging from self-limited lesions to life-threatening diseases. In most cases, a proper diagnosis can be established based on medical history and clinical features only. Early diagnosis is important as oral ulcerations might be a manifestation of a systemic disease or sometimes even due to a malignant process.

In a cross-sectional study, dental records of 149 individuals visiting an Academic Dental Clinic in Amsterdam who reported recreational ecstasy use, defined as no more than twice a week, were systematically analyzed and compared to a group of age- and sex-matched non-drug-users. The parameters retrieved from the dental records were decayed, missing, and filled permanent teeth-index (DMFT-index), number of endodontically treated teeth, presence of active caries lesions, periodontitis, tooth wear, xerostomia, and self-reported use of oral hygiene devices. Periodontitis, active caries lesions, and xerostomia were statistically significantly more present in ecstasy-users.

Purpose: Oral leukoplakia is the most common oral potentially malignant disorder with an annual malignant transformation rate of 1% to 5%. Consequently, oral leukoplakia patients have a 30% to 50% lifetime risk to develop oral squamous cell carcinoma. Although risk factors for malignant transformation of oral leukoplakia have been investigated, no definitive risk stratification model has been proposed.

Salivary stones (sialoliths) are calcified structures located in the ductal system of the major salivary glands. Their exact cause is not clear but in general they are characterized by concentric inorganic (hydroxyapatite) layers. The formation is a slow intermittent process which may result in enlargement of the sialolith causing obstruction of saliva secretion resulting in mealtime related pain and swelling of the affected salivary gland.

A periapical radiolucency, radiopacity or mixed lesion identified on a radiograph is usually caused by an inflammation of endodontic origin. However, a periapical lesion is sometimes caused by primary bone pathology, predominantly manifesting at the apices of the teeth. Various intraosseous lesions can also be projected across the apices, creating the impression of a causal relation with these teeth.
