s well as early diagnosis.

Hand and Upper limb pseudoaneurysms are uncommon and misdiagnosed. The delayed diagnostic and treatment lead to severe vascular and nerve complications. Many mechanisms are involved like acute injury, chronic micro traumatism of the hand, with specific clinic and para clinic signs.

The patient was a 30-years old woman, right-handed, admitted at the emergencies for a penetrating hand injury at the junction of the middle third - distal third of the left forearm, palmar surface, with a good radial and ulnar pulse, without sensory or motor deficit. No vessels injuries observed per operatively. A post-operative worsened pain opposite to the scar with a purplish pulsatile swelling appeared after 20 days of complete wound healing. A needle puncture with a red blood contain, motivated an US Doppler revealing a pseudoaneurysm of a superficial artery of the ulnar artery, surgically resected, without complication.

Two main mechanisms are involved in upper limb especially hand pseudoaneurysm penetrating trauma and repeated micro traumatism. Superficial vessels are rarely damaged compare to deep subfascial vessels according to Laplace law. The diagnostic is clinical confirmed with the medical imaging. A pseudoaneurysm is suspected in front of a pulsatile painful tumefaction following a vessel path, with medical imaging in favor. A delayed misdiagnosis lead to a delayed care with severe complications as thrombosis, embolism and vessel. The therapeutic care is mainly surgical.

This case reports a delayed diagnostic of posttraumatic pseudoaneurysm of a superficial branch of the ulnar artery, managed with a surgical resection.

Parathyroid gland has a distinct physiologic and endocrinologic role in the body system. Primary hyperparathyroidism is the most common cause of hypercalcemia with a marked female dominance. It is characterized by hypercalcemia, hypophosphatemia and elevated parathyroid hormone. Parathyroid adenoma, parathyroid hyperplasia and parathyroid carcinoma form the differential diagnosis. Giant parathyroid adenomas are rarely symptomatic than non-giant parathyroid adenomas and parathyroid carcinoma.

A 41 years old previously healthy male patient with undetectable surgical and familial history presenting with left clavicle fracture by mild trauma. He was diagnosed for primary hyperparathyroidism after the finding of multiple bony lesions and elevated serum calcium and Parathyroid hormone. Preoperative imaging aided in diagnosis of a parathyroid lesion and secondary bone resorption lesions (brown tumors). After adequate medical treatment and preparation, selective right lower parathyroidectomy was held, and the final pathology came with a giant parathyroid adenoma.

Primary hyperparathyroidism should be suspected when dealing with a hypercalcemic patient having osteolytic bony lesions. Distinguishing Parathyroid adenoma from carcinoma is a challenging and essential preoperative step in planning and surgical procedure.

The introduction of high-risk human papillomavirus (hrHPV) testing as part of primary cervical screening is anticipated to improve sensitivity, but also the number of women who will screen positive. Reflex cytology is the preferred triage test in most settings but has limitations including moderate diagnostic accuracy, lack of automation, inter-observer variability and the need for clinician-collected sample. Novel, objective and cost-effective approaches are needed.

In this study, we assessed the potential use of an automated metabolomic robotic platform, employing the principle of laser-assisted Rapid Evaporative Ionisation Mass Spectrometry (LA-REIMS) in cervical cancer screening.

In a population of 130 women, LA-REIMS achieved 94% sensitivity and 83% specificity (AUC 91.6%) in distinguishing women testing positive (n=65) or negative (n=65) for hrHPV. We performed further analysis according to disease severity with LA-REIMS achieving sensitivity and specificity of 91% and 73% respectively (AUC 86.7%) in discriminating normal from high-grade pre-invasive disease.

This automated high-throughput technology holds promise as a low-cost and rapid test for cervical cancer screening and triage. The use of platforms like LA-REIMS has the potential to further improve the accuracy and efficiency of the current national screening programme.

During muscle regeneration, excessive formation of adipogenic and fibrogenic tissues, from their respective fibro/adipogenic progenitors (FAPs), impairs functional recovery. Intrinsic mechanisms controlling the proliferation and differentiation of FAPs remain largely unexplored.

Here, we investigated the role of retinoic acid (RA) signalling in regulating FAPs and the subsequent effects on muscle restoration from a cardiotoxin-induced injury. selleck kinase inhibitor Blockage of retinoic acid receptor (RAR) signalling was achieved through dominant negative retinoic acid receptor α (RARα403) expression specific in PDGFRα+ FAPs in vivo and by BMS493 treatment in vitro. Effects of RAR-signalling on FAP cellularity and muscle regeneration were also investigated in a high-fat diet-induced obese mice model.

Supplementation of RA increased the proliferation of FAPs during the early stages of regeneration while suppressing FAP differentiation and promoting apoptosis during the remodelling stage. Loss of RAR-signalling caused ectopic adipogenic differentiation of FAPs and impaired muscle regeneration.
