The correct diagnosis is fundamental for the appropriate treatment to be employed in a particular pathology. The best treatment is not the one that solves only local problems, fragmenting the patient, and therefore, it is necessary to integrate the entire systemic condition of the individual before initiating any local treatment. This context inevitably requires dentistry to participate in a multidisciplinary approach, where the role of the dentist is expanded in concepts that encompass ethics, human dignity, and professional valorization. This article describes a clinical case of a patient with mucopolysaccharidosis type I, whose treatment of cystic lesions present in the mandible was exclusively performed through marsupialisation. The objective of this study is to demonstrate, within the complexity of this rare syndrome, the difficulties of diagnosis and the need for evaluation of the patient beyond the limits of the oral cavity, as well as to report two cases of large dentigerous cysts, surgically treated conservatively through marsupialisation, without the need for re-approach for enucleation and without recurrences over a 20-year period.

We present a case of obstruction in the third portion of the duodenum secondary to a phytobezoar in an adult patient with no surgical history and without a vegan diet. High intestinal obstruction due to a phytobezoar is rarely described in the literature, posing a diagnostic challenge when evaluating potential differentials in the emergency setting. Subsequently, we conduct a review focusing on tomographic findings and the surgical specimen, highlighting key points to consider when addressing such pathologies.

Second-generation antipsychotics (SGAs), also known as atypical antipsychotics, are a newer class of antipsychotic drugs used to treat schizophrenia, bipolar disorder, and related psychiatric conditions. The plasma concentration of antipsychotic drugs is a valid measure of the drug at its primary target structure in the brain, and therefore determines the efficacy and safety of these drugs. However, despite the well-known high variability in pharmacokinetics of these substances, psychiatric medication is usually administered in uniform dosage schedules. Therapeutic drug monitoring (TDM), as the specific method that can help personalised medicine in dose adjustment according to the characteristics of the individual patient, minimizing the risk of toxicity, monitoring adherence, and increasing cost-effectiveness in the treatment, thus seems to be an elegant tool to solve this problem. Non-response to therapeutic doses, uncertain adherence to medication, suboptimal tolerability, or pharmacokinetic drug-drug interactions are typical indications for TDM of SGAs. This review aims to summarize an overview of the current knowledge and evidence of the possibilities to tailor the dosage of selected SGAs using TDM, including the necessary pharmacokinetic parameters for personalised pharmacotherapy.

Takayasu arteritis is a large vessel vasculitis, characterized by granulomatous inflammation of arterial vessels, that typically affects the aorta, its main branches and pulmonary arteries. Disease diagnosis is a challenge and requires awareness of the condition, as clinical signs can be not specific. We report a case of an adolescent with recurrent stroke diagnosed with Takayasu arteritis. A diagnosis of Takayasu arteritis was established due to angiographic findings in the magnetic resonance angiography in conjunction with systolic blood pressure discrepancy, arterial hypertension and increased acute phase reactants. Takayasu arteritis is a rare cause of ischemic stroke in children. However, stroke may be the first manifestation of the disease. Clinical experience and multidisciplinary approach, including aggressive treatment, is essential for the favourable outcome of the disease and the reduction of the associated morbidity and mortality.

A middle-aged man in his 50s, active smoker, presented to the pulmonary office for lung cancer evaluation. On a low-dose computed tomography for lung cancer screening, he was found to have an 8 mm endobronchial lesion in the right main stem bronchus. A PET-CT revealed no endobronchial lesion, but incidentally, fluorodeoxyglucose (FDG) avidity was present in the right hilar (SUV 13.2) and paratracheal lymph nodes (LNs). He underwent bronchoscopy and EBUS-TBNA of station 7 and 10 R LNs. The fine needle aspiration (FNA) revealed necrotizing epithelioid granuloma. The acid-fast bacilli (AFB) and Grocott methenamine silver (GMS) stains were negative. He had suffered from pneumonic tularemia 13 months ago and immunohistochemical staining for Francisella tularensis on FNA samples at Center for Disease Control and Prevention was negative. The intense positron emission tomography (PET) avidity was attributed to prior tularemic intrathoracic lymphadenitis without active tularemia, a rare occurrence. To the best of our knowledge, PET-positive intrathoracic lymph node beyond one year without evidence of active tularemia has not been previously reported.

Cerebral air embolism after removal of central venous catheter (CVC) is a rare complication but can lead to fatal outcomes. We report a rare case of both cerebral venous and arterial embolism occurring in a patient with underlying scleroderma-related interstitial lung disease (SSc-ILD) and pulmonary hypertension following removal of percutaneous introducer sheath for pulmonary artery catheterization. We discuss the mechanisms, pathophysiology, management and prevention of cerebral air embolism.

Rheumatoid arthritis and osteoarthritis both affect the articular cartilage, and are characterized by signs and symptoms that can affect the functions of the human body. This cross-sectional observational study evaluated electromyographic activity in the masseter and temporalis muscles, molar bite force, and mandibular mobility in adult women with rheumatoid arthritis or osteoarthritis. A total of 42 women were distributed into 3 groups: rheumatoid arthritis group (ARG, n=14); osteoarthritis group (OAG, n=14); and a healthy control group (CG, n=14). Electromyography was used to evaluate mandibular tasks at rest, right and left laterality, protrusion, and dental clenching during maximum voluntary contraction, with and without parafilm, and a dynamometer was used to analyse the right and left molar bite forces. A digital caliper was used to measure the range of mandibular movement for maximum mouth opening, right and left laterality, and protrusion. Statistical analyses were performed, including analysis of variance and Tukey's test (P<0.05). Electromyography showed no significant differences between the groups when evaluating the masticatory muscles during the mandibular tasks. Significant difference was observed between the ARG and CG, however, in the maximum right (P=0.007) and left (P=0.02) molar bite forces. Significant difference was observed in the maximum mouth opening of the ARG and OAG groups compared with that of the CG (P=0.009), suggesting that adult women with rheumatoid arthritis or osteoarthritis experience functional alterations in the stomatognathic system, particularly in molar bite force and maximum mouth opening.

We present a case of a preterm neonate with a type IV laryngo-tracheo-oesophageal cleft, an uncommon congenital malformation, resulting from the failure of separation of the trachea and the oesophagus during fetal development, often associated with other deformities as well. Data in the literature shows that the long-term morbidity from the entity has declined over the last decades, even though prognosis remains unfavourable for types III and IV. This report emphasizes the complex issues neonatologists are faced with, when treating neonates with this rare disorder in the first days of life, what will raise suspicion of this rare medical entity, and that direct laryngoscopy/bronchoscopy finally depicts the exact extension of the medical condition. At the same time extensive evaluation for coexisting congenital anomalies should be performed. For all the above reasons, these neonates should be treated in specialized tertiary pediatric centers for multidisciplinary prompt management, which may improve, the outcome.

A 60-year-old woman came to the Emergency Department complaining of a vaginal formation. The urologist suspected a urethral caruncle: the patient was discharged with vaginal oestrogen cream to relieve symptoms and a follow-up was suggested. After two months the patient returned to the Emergency Department since the mass was increasing in volume and complaining of dysuria and haematuria. Ultrasound, contrast-enhanced computed tomography, and contrast-enhanced magnetic resonance revealed a mass arising from the mucosa and involving the vulva and the urethra, suspicious of malignancy. We present a challenging diagnosis of an infiltrative and rapidly progressive primary vulval amelanotic melanoma with a complete imaging evaluation and a confirmed histological diagnosis.

Endovascular treatment is widely applied as the first-line treatment for intracranial aneurysms and includes simple coiling (SC), stent-assisted coiling (SAC), flow diversion stent, and flow disruption stent. The present study is a retrospective cohort study performed in Imam Khomeini Hospital, Department of Neurovascular Intervention, between March 2016 and March 2021. A total number of 229 patients with intracranial aneurysms who underwent therapeutic intravascular interventions were enrolled, of which 89 were treated with SC, 111 with SAC, 25 with flow diversion stent, and 4 with flow disruption stent. The mean age of the subjects was 51.8±12.6 years, and 51.1% were male. Modified Raymond-Roy classification (MRRC) was used to define the occlusion outcome. The success rate, considered as Class I and Class II of MRRC at treatment time was 89% (94.4% in SC, and 84.7% in SAC), which was increased to 90.9% (94% in SC, 93% in SAC, 69.6% in flow diversion stenting, 100% in flow disruption) at 6-month follow-up, and 84.6% (80.8% in SC, 87.8% in SAC, 78.3% in flow diversion stenting, and 100% in flow disruption) at 12-month follow-up. The mean modified Rankin Scale (mRS) before the procedure was 0.05±0.26 which was increased to 0.22±0.76 after the procedure, 0.22±0.76 at 6 months, and 0.30±0.95 at 12 months (P<0.001). Similar to previous studies, the present study demonstrates that neurovascular intervention can treat ruptured aneurysms as the first therapeutic modality with favourable outcomes. A double-blind, randomized clinical trial is needed to eliminate the confounding factors and better demonstrate the outcome.
