Introduction: Adenoid Cystic Carcinoma of the sinonasal and skull base region is a challenging tumor to treat due to its late onset of presentation and frequent compromise of vital neurovascular structures. Surgical treatment followed by conventional irradiation are the optimal treatment options, often requiring extensive open approaches and mutilating interventions due to its localization. Endoscopic endonasal approaches are relatively new procedures that combined with new adjuvant radiation techniques could achieve similar oncological outcomes with significant less morbidity. Methods: We present the case of a patient with non-metastatic Adenoid Cystic Carcinoma (ACC) locally advanced of the sinonasal and skull base region diagnosed and treated at the Instituto Nacional de Cancerología of Bogotá D.C, Colombia between the years 2017 and 2020 who underwent endoscopic endonasal tumor resection and subsequent adjuvant management with Intensity modulated radiotherapy (IMRT). Results: Endoscopic and imaging control was performed according to the protocol of the surgical group with nasal endoscopies every 3-4 months during the first 2 years and serial images every 6 months. Follow up for 35 months with adequate local control and minimal aesthetic or functional sequelae. Conclusion: Multidisciplinary management with endoscopic endonasal resection and adjuvant radiotherapy appears to be an effective oncological alternative to open surgical procedures, with less morbid and minor functional sequelae, for patients with locally advanced ACC tumors of the sinonasal region.

objectified Abstract Introduction: Temporal bone fractures often lead to loss of audio-vestibular function. Otic capsule violating fractures are associated with higher incidence of Sensorineural hearing loss than otic capsule sparing fractures. Material and methods: Prospective study conducted at the Mohammed VI University Hospital center of Marrakech, from January 2013 to June 2017, covering 23 cases of sensorineural hearing loss in the context of Temporal bone trauma. Results: The mean age was 31 years (4-56 years), with a clear male predominance (sex ratio 21/2). Clinical symptomatology was characterized by hearing loss in all our patients, otorrhagia in 20 cases, vertigo in 13 cases, facial paralysis in 10 cases, and otoliquorrhea in 5 cases. 96% of patients presented with labyrinthine fractures. Two cases of pneumolabyrinth and one case of bilateral temporal bone fracture were noted. The audiometry showed sensorineural hearing loss in 9 cases and mixed in 14 cases. In one case the hearing loss was bilateral with severe sensorineural hearing loss on one side and moderate on the other side. Conclusion: Temporal bone fracture is one of the most common traumatic injuries that can cause loss of auditory and vestibular function. The diagnosis must be made within a few hours after the trauma, as the auditory prognosis depends on the earliness of the management. Auditory sequelae can go as far as complete hearing loss, on the affected side.

causes of refractory hypothyroidism and approach for its diagnosis and management. Abstract A group of hypothyroid patients fails to achieve euthyroidism despite high doses of levothyroxine. These patients are designated as treatment refractory hypothyroidism. The prevalence of treatment-refractory hypothyroidism is not established. Noncompliance is one of the major issues in such cases .Other than noncompliance; impaired absorption due to gastrointestinal disease is a possibility. To achieve the target TSH or euthyroidism commonly the dose of levothyroxine is gradually increased but it may increase few adverse outcome, cost of investigation, follow up and treatment. Suspected patients should undergo a systematic approach for evaluation and management of this condition. In such a situation, there is a need to search for causes of decreased absorption of thyroxine or increased demand for thyroxine .This evaluation may help to reveal few underlying diseases and management of that disease may help to cure the refractoriness of levothyroxine replacement. An alternative formulation of levothyroxine may be prescribed to overcome the situation before going for detailed investigation.

Background: Most patients with acute respiratory distress syndrome (ARDS) due to COVID-19 warrant intubation and mechanical ventilation (MV). Methods : As COVID-19 is a relatively new disease to us, with distinct clinical and pathophysiologic features and with massive burden on the health care facilities, particularly the intensive care units (ICUs), it is wise to think in using tools that are feasible, easy and save time and money. Previous studies showed that modified Burns wean assessment program (mBWAP) is a good predictor of weaning success. Results: mBWAP proved useful as a good predictor of successful weaning and extubation in patients requiring long-term MV longer than 21 days, as well as in patients with respiratory disorders admitted to the respiratory ICU. Conclusion: Previous data for mBWAP are encouraging and deserve utilizing it as a predictor tool for weaning from MV in patients with COVID-19. Further prospective studies are warranted.

Young children are known for their curious ways of exploring their surroundings. As a normal part of their development, they use all senses to familiarize themselves with new objects. Every new texture, smell, color, or taste will naturally attract a child and entice them to further explore. This instinctive behavior can however lead a child into harm’s way. The same curiosity that enhances their development can also pose a risk of accidental ingestion of foreign body [1,2]. These incidences become dangerous and complications vary in severity depending on the type of foreign body ingested, the duration until the time of presentation and site of impaction [1,2]. The most common objects accidently ingested by children are coins. However, many of these incidences are unwitnessed by the child’s guardians. An x-ray revealing a coin shaped object may in fact be something far more dangerous, such as a button battery. Button batteries are easily accessible to children as they are found in different toys and electronic devices. Due to their higher risk of causing complications, prompt intervention is required. A button battery appears as a circular, radiopaque object with a double halo or rim on an anteroposterior (AP) x-ray film [3,4]. However, these characteristics do not always confirm that the object is in fact a button battery. In our case, we are going to show that sometimes the double rim seen on an x-ray can be attributed to other types of ingested foreign bodies.

Dental Stem cells are undifferentiated cells isolated from tooth and associated structures. Dental stem cells can be easily obtained from both adult and deciduous teeth, the periodontal ligament, the apical papilla and the dental follicle. Their subsequent differentiation can be utilized to replace the lost tooth structures. Here we aim to highlight potential of dental stem cells from varied origin for tooth regeneration. Several studies have demonstrated tooth tissue regeneration. Application of recent 3D bioprinting technology has further enhanced probability of accurate tooth tissue regeneration. However complete tooth regeneration is still a future thing.

Oral cancer is a global health problem with growing incidence and mortality rates. As highlighted by International Agency for Research on Cancer and World Health Organization on 2014, the early diagnosis of oral cancer reduces morbidity and mortality rates. The most accepted mode of initial definitive treatment for most oral cancers is surgical management. Various factors related to the primary Tumour and the patient affect choice of treatment. Primary site, location, size, proximity to bone, and depth of infiltration are factors which influence a particular surgical approach. Tumour’ s that approach or involve the mandible require specific understanding of the mechanism of bone involvement. Over time the role of surgery in primary squamous cell carcinomas in other sites in the head and neck has evolved with integration of multidisciplinary treatment approaches employing chemotherapy and radiotherapy either sequentially or concurrently. In this article, we throw light on the numerous component that influence the decision making of the surgeon before surgical resection in oral cancer.

Background: Osteoma, fibrous, dysplasia and ossifying fibroma are fibro-osseus lesions that can occur in the paranasal sinuses, management of these lesions can be technically challenging due to proximity to the orbit and skull base, with the advancement in endoscopic endonasal surgery and development of technologies such as image guidance can improve the safety of endoscopic removal and improve its safety. Illustrative cases : Three cases of fibro-ossuoes lesions are presented in this study an adult female with left frontoethmoidal osteoma, an adult male with left ethmoid fibrous dysplasia, both of whom have been treated with pure endonasal endoscopic approach with image guidance, the third case is a male child with juvenile ossifying fibroma, he was treated initially with the endoscopic approach with image guidance, but had a skull base recurrence 6 months later which was removed with an open craniotomy approach. Conclusion: Image guidance is a valuable tool in improving safety and efficiency of endoscopic sinus surgery particularly in challenging cases such as fibro-osseus lesions with proximity to the skull base and orbit.
