We present a 49-year-old woman with a history of an unresectable nasopharyngeal small cell carcinoma (SCC) who was treated with concurrent chemotherapy and radiation therapy. On surveillance positron emission tomography scan 14 months after diagnosis, her primary tumour appeared stable, but there was fludeoxyglucose uptake in the pancreas. A CT scan demonstrated a 3.4×2.1 cm ill-defined soft tissue mass at the tail of the pancreas, which was concerning for adenocarcinoma. However, further workup including endoscopic ultrasound and fine needle aspiration confirmed the mass to be a metastasis from her nasopharyngeal SCC. Because there have been no previously reported cases of a metastatic small cell carcinoma to the pancreas, there are no data about prognosis. Thus treatment options were tailored to the patient. Distal pancreatectomy, splenectomy and cholecystectomy were performed. The patient recovered from surgery without complication.We report the first case of a healthy 24-year-old male with a 6-year history of regular cannabis use, who presented with haemoptysis after a shallow 3 m breath-hold dive. Blood investigations showed mild neutrophilia. CT thorax revealed focal ground-glass changes in the superior segment of the lower lobe. ANA-12 order With a suspicion of pneumonia, oral antibiotics were initiated to poor effect. Through bronchoscopic visualisation and lavage, a diagnosis of diffuse alveolar haemorrhage was established. The clinical course was benign with resolution of symptoms and changes on CT thorax within 6 weeks of stopping marijuana use. Since all other causes of haemoptysis were excluded, pathophysiology was attributed to cannabis-induced lung parenchymal damage, exacerbated by a shallow breath-hold dive. To ensure appropriate management, a clinician should therefore have a high index of suspicion for drug use and other factors known to cause chronic lung damage in whom other causes of diffuse alveolar haemorrhage are excluded.Serous adenofibroma of the fallopian tube is a rare, benign tumour of the female genital tract. They are usually small, asymptomatic and incidentally diagnosed during a surgery for another gynaecological condition. This report presents an atypical case of a 17-year-old girl with a tubal serous adenofibroma that presented with a palpable mass occupying the entire abdomen accompanied by urinary symptoms. She underwent a laparoscopic surgery with drainage of 1800 mL of yellow, citrine liquid from the cyst and left salpingectomy with no complications.We report two cases of successfully treated intracranial saccular aneurysms via transradial access with aberrant right subclavian artery anatomy. Two patients aged 74 and 82 years with anterior communicating artery aneurysms deemed suitable for endovascular treatment and anomalous aortic arch anatomy (aberrant right subclavian artery) underwent successful treatment with transradial access. Transradial access was obtained in both patients, in the first patient, without prior knowledge of the aortic arch anatomy. Aberrant right subclavian artery anatomy was negotiated, and the aneurysms were successfully treated in both cases with intrasaccular flow disrupting devices (WEB-SL). The study aims to discuss a case of an uncommonly sited rare tumour causing nasal obstruction and a literature review of angioleiomyomas in the nose. A 64-year-old woman presented with blockage of the right nostril, associated with a visible swelling on the undersurface of the alar cartilage, in the lateral wall of the nasal cavity. Anterior rhinoscopy highlighted a 1 cm cystic lesion, with areas of firmness, present at the mucocutaneous junction with a broad base. It was not attached to the underlying cartilage. There was no ulceration or bleeding on palpation. Nasal endoscopy did not show any extension further and the rest of the nasal cavity was clear. Endonasal resection of the tumour using a two-handed technique. This paper highlights not only the importance of considering angioleiomyomas within a differential diagnosis of nasal obstructions but also the uncommon site. .This paper has two main purposes (1) to report a rare case of paediatric gliosarcoma that invaded the surrounding orbit and (2) to demonstrate chlorpromazine injection as a potential treatment option for blind, painful eye caused by tumour invasion. A 12-year-old man who presented with headaches was found to have glioblastoma multiforme and it was excised and treated with radiation and chemotherapy. Seven months later, the tumour recurred as gliosarcoma, a rare variant of glioblastoma multiforme containing distinct gliomatous and sarcomatous components. In spite of treatment, the tumour progressed and eventually invaded into the right orbit. He subsequently developed a proptotic, blind, painful eye and was treated with retrobulbar chlorpromazine injection, which provided immediate symptomatic relief.While the benefits of both hydrogels and drug delivery to enhance wound healing have been demonstrated, the highly hydrophilic nature of hydrogels creates challenges with respect to the effective loading and delivery of hydrophobic drugs beneficial to wound healing. Herein, we utilize pressurized gas expanded liquid (PGX) technology to produce very high surface area (~200 m2/g) alginate scaffolds and describe a method for loading the scaffolds with ibuprofen (via adsorptive precipitation) and crosslinking them (via calcium chelation) to create a hydrogel suitable for wound treatment and hydrophobic drug delivery. The high surface area of the PGX-processed alginate scaffold facilitates >8 wt% loading of ibuprofen into the scaffold and controlled in vitro ibuprofen release over 12-24 h. In vivo burn wound healing assays demonstrate significantly accelerated healing with ibuprofen-loaded PGX-alginate/calcium scaffolds relative to both hydrogel-only and untreated controls, demonstrating the combined benefits of iout the need for any pore-forming additives. The impregnated scaffolds significantly accelerated burn wound healing while also promoting regeneration of the native skin morphology. We anticipate this approach can be leveraged to load clinically-relevant and highly bioavailable dosages of hydrophobic drugs in hydrogels for a broad range of potential applications.
