The application of three-dimensional printing in the management of a difficult airway due to Treacher Collins syndrome.

We describe the use of three-dimensional printing to create precise airway models for a patient with Treacher Collins syndrome who presented for bimaxillary temporomandibular joint prostheses, and for whom airway management was predicted to be difficult. The model was based on pre-operative cone beam computed tomography images and printed in the 3D Lab of Hospital Universitario La Paz. Transparent models allowed clear visualisation for simulation and iterative refinement of airway management techniques and aided in risk assessment and instrument sizing. This case report emphasises the utility of this approach in complex airway scenarios.

Prevalencia y fenotipo de la hiperplasia suprarrenal macronodular bilateral primaria con secreción autónoma de cortisol: un estudio de 98 pacientes / Prevalence and phenotype of primary bilateral macronodular adrenal hyperplasia with autonomous cortisol secretion: a study of 98 patients

Objetivo Se evaluó la prevalencia de hiperplasia suprarrenal macronodular bilateral primaria (PBMAH). También se analizó el fenotipo diferencial de los pacientes con PBMAH en comparación con otras lesiones suprarrenales bilaterales que no cumplían con la definición de PBMAH. Métodos Revisamos las historias clínicas de 732 pacientes diagnosticados de incidentaloma suprarrenal en nuestro centro. Se incluyeron 98 pacientes con hipercortisolismo subclínico para el análisis. Se definió PBMAH como la presencia de cortisol plasmático > 1,8 μg/dL después de una prueba de 1 mg de dexametasona durante la noche, hiperplasia suprarrenal bilateral y nódulos suprarrenales bilaterales > 1 cm. Resultados Un total de 31 pacientes tenían PBMAH. Los pacientes con PBMAH mostraron una mayor prevalencia de secreción autónoma de cortisol (cortisol plasmático > 5,0 μg/dL después de la prueba de 1 mg de dexametasona durante la noche) que los pacientes sin PBMAH (OR 4,1, IC del 95%: 1,38-12,09, p = 0,010). El tamaño del tumor y la masa adenomatosa total fueron significativamente mayores en pacientes con PBMAH en comparación con los pacientes sin PBMAH (30,2 ± 12,16 vs. 24,3 ± 8,47 mm, p = 0,010 y 53,9 ± 20,8 vs. 43,3 ± 14,62 mm, p = 0,023), respectivamente. Una mayor proporción de pacientes con PBMAH tenían diabetes en comparación con los pacientes sin PBMAH (45,2% vs. 25,4%, p = 0,05). Conclusión PBMAH está presente en un tercio de los pacientes con incidentaloma suprarrenal e hipercortisolismo subclínico. Los pacientes con PBMAH mostraron una mayor secreción autónoma de cortisol, mayor tamaño del tumor y diabetes que aquellos sin PBMAH (AU)

Aim This study evaluated prevalence of primary bilateral macronodular adrenal hyperplasia (PBMAH). It also analyzed the differential phenotype of patients with PBMAH compared to other bilateral adrenal lesions that do not meet the definition of PBMAH. Methods We reviewed the medical records of 732 patients diagnosed with an adrenal incidentaloma at our center. Ninety-eight patients with subclinical hypercortisolism were included in the analysis. We defined PBMAH as the presence of plasma cortisol > 1.8 μg/dL after an over-night 1-mg dexamethasone test, bilateral adrenal hyperplasia, and bilateral adrenal nodules > 1 cm. Results A total of 31 patients had PBMAH. Patients with PBMAH showed greater prevalence of autonomous cortisol secretion (plasma cortisol > 5.0 μg/dL after an overnight 1-mg dexamethasone test) than patients without PBMAH (OR 4.1, 95%CI 1.38-12.09, p = 0.010). Tumor size and total adenomatous mass were significantly greater in patients with PBMAH compared to patients without PBMAH (30.2 ± 12.16 vs. 24.3 ± 8.47 mm, p = 0.010 and 53.9 ± 20.8 vs. 43.3 ± 14.62 mm, p = 0.023), respectively. A greater proportion of patients with PBMAH had diabetes compared to patients without PBMAH (45.2% vs. 25.4%, p = 0.05). Conclusion PBMAH is present in one-third of patients with adrenal incidentaloma and subclinical hypercortisolism. Patients with PBMAH showed greater autonomous cortisol secretion, bigger tumor size, and higher rates of diabetes than those without PBMAH (AU)

Navigation in surgical arthroscopy of the temporomandibular joint.

Surgical navigation is a technique that has evolved greatly in recent years. It allows surgeons to navigate through the surgical field in real time, and helps to locate anatomical structures or lesions and to place devices in complex anatomical regions with relatively high accuracy. In this article, we describe the application of surgical navigation in temporomandibular joint (TMJ) arthroscopy using an optical surgical navigator for a more precise diagnosis and to accurately place instruments in the desired position, especially in lateral pterygoid myotomy. We believe this technique will extend our understanding of the TMJ anatomy and will improve functional results in TMJ arthroscopy.

Clinical nutrition as part of the treatment pathway of pancreatic cancer patients: an expert consensus

PurposeMalnutrition is a common problem among pancreatic cancer (PC) patients that negatively impacts on their quality of life (QoL) and clinical outcomes. The main objective of this consensus is to address the role of Medical Nutrition Therapy (MNT) into the comprehensive therapeutic management of PC patients.MethodsA Spanish multidisciplinary group of specialists from the areas of Medical Oncology; Radiation Oncology; Endocrinology and Nutrition; and General Surgery agreed to assess the role of MNT as part of the best therapeutic management of PC patients.ResultsThe panel established different recommendations focused on nutritional screening and nutritional screening tools, MNT strategies according to PC status, and MNT in palliative treatment.ConclusionsThere is an unmet need to integrate nutritional therapy as a crucial part of the multimodal care process in PC patients. Health authorities, health care professionals, cancer patients, and their families should be aware of the relevance of nutritional status and MNT on clinical outcomes and QoL of PC patients.

Medication related osteonecrosis of the jaws (MRONJ): Factors related to recurrence after treatment with surgery and platelet rich plasma (PRP) placement.

BACKGROUND: Medication-related osteonecrosis of the jaws (MRONJ) is a well-known complication associated with antiresorptive and antiangiogenic therapies. The purpose of this study was to analyse if there is any predictive factor of recurrence after local debridement plus platelet rich plasma (PRP) placement in MRONJ patients. MATERIAL AND METHODS: Seventy MRONJ patients treated at the department of Oral and Maxillofacial Surgery in La Paz Hospital (Madrid, Spain) were included in this retrospective study. All of them were treated surgically by local debridement and PRP placement. The observation period was between January 2012 and January 2019. Information regarding use, type, administration, and duration of therapy with BP/denosumab was recorded. The follow-up period ranged from 2-52 months. A descriptive analysis, a bivariate and a multivariate study were performed. RESULTS: Most of the patients were women (82.9%) between 50-70 years old (64.3%), with a stage II disease (74.3%). The therapy lasted more than 12 months in 54.8% of them. Zoledronic acid was the main antiresorptive used (44.3%), followed by oral administered BPs (29 patients, 41.4%) and denosumab (10 patients, 14.3%). Osteoporosis (48.6%), breast cancer (30%) and multiple myeloma (11.4%) were the main diseases because the patients were taking antirresorptives. 13 patients (18.6%) experienced recurrence. We found that breast cancer patients (p>0.0001), smokers (p>0.016), and administration of zoledronic acid (p>0.0001) were related to recurrence. After performing the multivariate model, we found that the only factor related to recurrence was smoking habit (Wald 3.837, p=0.05, OR 6.12). CONCLUSIONS: recurrence after local debridement plus PRP placement in our MRONJ series affected to 18.6% of patients. It seems to be more frequent in breast cancer patients, smokers, and after zoledronic acid administration. Smoking habit was the only independent factor related to recurrence in our series.
