Popliteal artery entrapment syndrome (PAES), a condition predominantly affecting young individuals, is a rare clinical entity that can result in significant morbidity. The presence of lower limb pain and claudication in young, physically active individuals should prompt consideration for PAES. Early diagnosis and management is crucial to prevent long-term complications; however, diagnosis is fraught with challenges due to the rarity of the disease and its similar clinical presentation with more common conditions...

Allergic conjunctivitis (AC) includes a wide spectrum of clinical entities characterized by different incidence, age of onset, natural course, clinical outcome and response to treatment. Taken together, they represent one of the most frequent ocular surface diseases affecting more than 30% of the young-adult population and show an increasing incidence over the years. Moreover, comorbidities with other systemic atopic conditions such as asthma, atopic dermatitis and rhinitis require a multidisciplinary approach...

Purpose: The eyelid is commonly dissected and divided in the process of, for example, blepharotomy, entropion repair, or when preparing a full-thickness eyelid flap to reconstruct a tumor defect. No study has yet been conducted to examine how perfusion in an eyelid is affected by dissection, using modern imaging techniques. Methods: The eyelid was divided with a 10-mm vertical incision, 5 mm from the medial canthus, and the incision was extended horizontally by 30 mm to provide a full-thickness eyelid. Blood perfusion was measured along the length of the free dissected eyelid using both laser Doppler velocimetry and laser speckle contrast imaging...

Gustatory and olfactory senses of phytophagous insects play important roles in the recognition of host plants. In the domestic silkmoth Bombyx mori and its wild species Bombyx mandarina, the morphologies and responses of adult olfactory organs (antennae) have been intensely investigated. However, little is known about these features of adult gustatory organs and the influence of domestication on the gustatory sense. Here we revealed that both species have two types of sensilla (thick [T] and slim [S] types) on the fifth tarsomeres of the adult legs...

Tibialis anterior tendon rupture is a relatively rare injury, with diverse etiologies, that can cause significant deficits in the functionality of the ankle. These injuries are sometimes diagnosed too late, being in many occasions the alteration in walking the symptom that makes the patient go to the doctor. The six weeks will mark the limit between acute and chronic injury, requiring different therapeutic approaches, along with other parameters such as age, functional demand or concomitant pathologies. OBJECTIVE: To present two cases of acute rupture, with different etiology, the surgical technique used and the final results...

A small number of koalas ( Phascolarctos cinereus) presented to wildlife hospitals in Queensland, Australia, with signs of arthritis in one or more joints. Molecular analysis identified Chlamydia pecorum in the tarsal tissue and synovial fluid of an affected joint of a koala, suggesting that in addition to livestock, C. pecorum has the potential to cause arthritis in the koala.

Plexiform neurofibromas of the foot are rare, benign tumors of the peripheral nerves. Diagnosis can be challenging if they present with symptoms mimicking other peripheral nerve pathologies. Tarsal tunnel syndrome is an entrapment syndrome of the entire tibial nerve behind the medial malleolus and under the flexor retinaculum. The clinical presentation typically includes posteromedial pain, positive Tinel's sign, and neurogenic signs, including both the sensation of numbness and the actual hypoesthesia and clawing of the toes...

BACKGROUND: Rhinosporidiosis is a rare chronic infection of the mucous membranes caused by the Rhinosporidium seeberi. Approximately 15% of cases of rhinosporidiosis are ocular, occurring mainly in the tarsal conjunctiva. There are only 11 cases of scleral melt with staphyloma formation associated with bulbar conjuctival oculosporidiosis and none of them was associated with partial regression of the scleral ectasia after a corneoscleral tectonic graft. CASE PRESENTATION: a 13-year-old girl with a progressively increasing black mass in the upper nasal part above the cornea of the left eye...

On the island of Sardinia the lepidopteran Papilio hospiton uses Ferula communis as exclusive host-plant. However, on the small island of Tavolara, adult females lay eggs on Seseli tortuosum, a plant confined to the island. When raised in captivity on Seseli only few larvae grew beyond the first-second instar. Host specificity of lepidopterans is determined by female oviposition preferences, but also by larval food acceptance, and adult and larval taste sensitivity may be related to host selection in both cases...

The tarsal navicular is a critical component of the foot's medial longitudinal arch. Injuries to the navicular have significant long-term functional consequences. In addition to stress fractures, acute injuries to the navicular include acute avulsion, tuberosity, and body fractures. Nonoperative treatment is the mainstay for avulsion injuries and nondisplaced body fractures. Open reduction and internal fixation is performed to achieve anatomic reduction in the other situations. Common complications following operative intervention include pain, stiffness, post-traumatic arthritis, avascular necrosis, nonunion, and hindfoot deformity...

Importance: Gait impairments are common in patients with chronic supratentorial upper motor neuron lesions and are a source of disability. Clinical management aimed at improving the gait pattern in these patients is generally perceived as a challenging task because many possible abnormalities may interact. Moreover, a multitude of treatment options exist, ranging from assistive devices and muscle stretching to pharmacologic and surgical interventions, but evidence is inconclusive for most approaches and clear treatment guidelines are lacking...
