Acquired tracheo-oesophageal fistula (TOF) is a rare complication of intubation or traumas, either blunt or penetrating. In a penetrating chest trauma, the closure of TOF can be challenging and requires a unique technique. Perifosine A flap can and intra-tracheal tube can also be used. We present this case to demonstrate a unique late presentation of TOF and the unique approach that was used.
A patient presented with a large TOF caused by shrapnel, and was surgically managed after two months of the injury by using a smaller intra-tracheal tube, and using an oesophageal wall flap to close the tracheal defect and intercostal muscle flap was used for the oesophageal wall repair. The postoperative intrathoracic oesophageal leak was successfully treated conservatively.
Although the surgery could not be conducted until 2 months after the injury, the approach used was successful and the patient was able to resume his normal life after the surgery. The flap from the oesophagus and intercostal muscles and using a smaller tracheal tube successfully repaired the TOF with minimum stress on the suterings, and the conservative approach for the leak was also successful.
Traumatic TOF management can be complicated, but we speculate that using a smaller tube with the conservative management of the complications was ideal for the TOF acquired from a shrapnel.

the solitary plasmacytomas entities characterized by the neoplastic proliferation of a single clone of plasma cells, typically producing a monoclonal immunoglobulin. It represents less than 5% of plasma cell dyscrasias. The most common sites of solitary plasmacytomas are long bones. The jaws location remains extremely rare, only 4.4% of solitary plasmacytomas of bone occur in the mandible, the diagnosis is based on the biopsy evidence of plasma cell proliferation and absence of evidence of involvement of other bones.
The authors report the case of a healthy 49-year-old man with no general history, presented with a painless slow-growing lesion of the left jaw that had persisted and increased in size for one month. Clinical examination revealed a large lesion 4×4cm with irregular borders of the retro-molar area on the left jaw, infiltrated into underlying tissue, with sensory disturbances and facial asymmetry.
Treatment methods of plasmacytomas of the jaw include local surgery (curettage of the lesion), local irradiation, systemic chemotherapy, or a combining therapy. Early diagnosis and treatment are crucial for better resolution of the disease.

Gastrointestinal (GI) tract perforations are a significant source of morbidity in clinical practice; therefore, an early diagnosis is fundamental for early management. In management, surgery is the definitive therapy; however, there is evidence of a strong response to conservative measurements.
A 53-year-old man known for a laparoscopic cholecystectomy with difficult access and postoperative complications was admitted to our emergency department due to a five-day clinical history comprising acute abdominal pain and feverish peaks up to 38.4°C. Diagnosis methods CT and NMR were performed but did not lead to a clear diagnosis. Therefore, a EUS was performed observing an anechoic path that communicates the duodenal wall with a right subhepatic collection that was in contact with the proximal bile duct, thickening its walls. A 5mm fistulous orifice was found. The hepatoduodenal fistula was close endoscopically with the over-the-scope-clip OVESCO OTSC. Post endoscopic closure course was uneventful.
Duodenal fistulae are considered one of the most serious complications in gastrointestinal surgery, when conventional diagnosis methods do not permit the clinicians to get either a medical diagnosis or the management; the EUS can. Advances in interventional endoscopic techniques offer an alternative management for the closure of GI fistulae.
Whenever the presence of an organized fistula is clinically suspected, EUS can be considered a useful tool that allows not only the characterization of the fistulous path and but also the definition of the minimally invasive endoscopic treatment.

Herein, we investigated cell internalization of soft hyaluronic acid (HA) nanoplatelets (NPs) that exhibit a typical hexagonal shape, flat surfaces and high aspect ratio (Γ≈12 to 20), as characterized by atomic force microscopy in hydrated conditions. Fluorescence imaging revealed that internalization of HA-NPs by a T24 tumor cell line and by macrophages was higher than native polysaccharide in a dose-dependent and time-dependent manners. The ability of HA-NPs to efficiently compete with native HA assessed using Bio-layer interferometry showed that NPs had a stronger interaction with recombinant CD44 receptor compared to native HA. The results were discussed regarding physical properties of the NPs and the implication of multivalent interactions in HA binding to CD44. Experiments conducted on supported bilayer membranes with different compositions showed that non-specific interactions of NPs with lipid membranes were negligible. Our findings provide insights into intracellular drug delivery using soft HA-NPs through receptor-mediated multivalent interactions.
