Spontaneous bilateral patellar tendon rupture: case report and review of fluoroquinolone-induced tendinopathy.

The present case emphasizes the importance of adhering to strict indications when prescribing fluoroquinolones. Although rare, drug‐induced tendinopathy is not confined to fluoroquinolones. The patients and physicians awareness should be increased to reduce fluoroquinolones‐associated morbidity, particularly in patients with previously described risk factors.

Tarsal navicular fracture in a parkour practitioner, a rare injury – case report and literature review

Tarsal navicular fractures, as well as other midfoot injuries, are rare, and can result in severe impairment if not properly treated. Parkour, a modern sport, is gaining popularity among young individuals in urban areas, and is prone to result in high-energy trauma, which is scarcely described in the literature. The following is a report of a rare case of tarsal navicular fracture in a 17-year-old male, sustained during parkour practice, which was treated successfully with open reduction and internal fixation. The description of the case emphasizes the challenges of its approach; the discussion highlights the treatment options and goals. The case should also raise awareness about the increasing occurrence of these uncommon lesions.

Nora’s Lesion: A Rare Tumor in the Pediatric Population

Nora’s lesion or bizarre periosteal osteochondromatous proliferation, first described by Nora in 1983 [1], is a very rare condition with only about 160 cases being described in the literature since then [2,3]. It is more common in adults, in their third to fourth decade [1,2,4] and occurs mostly on the proximal and middle phalanges, metacarpal and metatarsal bones [5]. The etiology of this lesion remains unknown. Some authors hypothesized that traumatic events could be on the origin of it [6]. However, actually there is no evidence of a relationship between trauma and bizarre periosteal osteochondromatous proliferation. Radiologically, it appears as a calcified mass attached to the bone cortex [1] and can mimic an exostosis, an osteochondroma or a malignant condition [7].

A rare case of digital myiasis

Cutaneous myiasis is the infestation of the skin or mucous membranes by larvae of the order Diptera. Wound myiasis affect the skin with a previous lesion, and it may consume both dead and living tissue. Finger infestation is rarely a cause of death, but it may provoke considerable morbidity. Prompt wound exploration and careful total larvae removal is essential to achieve healing. In the reported case, the patient was presented in an advanced stage of the infestation, with a large area of finger necrosis and amputation, associated with cellulitis extending from the fingers base to the hand. This diagnosis helped uncover a familiar history of severe abuse and neglect. The accurate understanding and management of such injuries are important not only for the orthopaedic treatment but also for the acknowledgment of their social and forensic implications.

Thromboelastometry-guided blood transfusion in septic shock complicated with disseminated intravascular coagulation: a case report

Approximately 25–50% of septic patients develop disseminated intravascular coagulation. The thromboelastometry evaluates whole blood clot formation and dissolution in real time and has been considered for management of bleeding in diverse clinical conditions. We present a case of thromboelastometry‐guided bleeding management of a septic shock patient with overt disseminated intravascular coagulation (DIC).

Solitary bone plasmacytoma of the pelvis: a rare tumor

Solitary bone plasmacytomas are part of a wide range of monoclonal neoplasms that share a common progenitor in the B lymphocyte lineage. In their particular case, a single bone lesion is found, most frequently on the axial skeleton, having evidence of no other osteolytic lesions or systemic involvement. Diagnosis can sometimes prove to be difficult as they are rare tumors, occurring in 3 to 5% (up to 10% in some series) of patients with plasma cell neoplasms, with important considerations regarding the differential diagnosis. We report a case of a solitary bone plasmacytoma, found on the ala of the left ilium of a patient during a routine consult due to hip pain.

Spinous Process Osteochondroma as a Rare Cause of Lumbar Pain

We present a case of a 5th Lumbar Vertebra (L5) spinous process osteochondroma as a rare cause of lumbar pain in an old patient. A 70-year-old male presented with progressive and disabling lower lumbar pain. Tenderness over the central and left paraspinal area of the lower lumbar region and a palpable mass were evident. CT scan showed a mass arising from the spinous process of L5. Marginal resection of the tumor was performed through a posterior approach. The histological study revealed an osteochondroma. After surgery, pain was completely relieved. After one year there was no evidence of local recurrence or symptoms. Osteochondromas rarely involve the spine, but when they do symptoms like pain, radiculopathy/myelopathy, or cosmetic deformity may occur. The imagiologic exam of election for diagnosis is CT scan. When symptomatic the treatment of choice is surgical resection. The most concerning complication of osteochondromas is malignant transformation, a rare event.
