Optical coherence tomography angiography (OCTA) is a noninvasive, rapid imaging technique that generates angiographic images without intravenous dye injections. Cross-sectional studies have described the presence of asymptomatic choroidal neovascularization (CNV) in patients with intermediate age-related macular degeneration (AMD). This case report describes the OCT features on longitudinal follow-up of a patient who started with unilateral asymptomatic CNV and eventually developed symptomatic exudative AMD...

INTRODUCTION: Freiberg's infraction is an osteonecrosis affecting the metatarsal head whose pathogenesis is not fully understood, although stress overloading by multiple microtraumas remains the most widely accepted cause. Operative treatment, by different techniques, is necessary when conservative treatment fails. PRESENTATION OF CASE: A 31-year old woman presented with left foot severe pain, especially at the level of the metatarsophalangeal joint (MTPJ) of the second ray, underestimated upon initial evaluation...

Xanthogranulomatous cystitis (XC) is a rare condition affecting the bladder thought to be caused by chronic inflammation. Fewer than 30 cases have been reported in the literature since being first described in 1932. We present the first reported case of XC in a pre-pubertal male and review the literature. A 10-year-old boy presenting with dysuria subsequently developed frequency. After failure of conservative management, an ultrasound of the bladder revealed a mass. The patient underwent partial cystectomy...

The Achilles tendon has a unique structure-function relationship thanks to its innate hierarchical architecture in combination with the rotational anatomy of the sub-tendons from the triceps surae muscles. Previous research has provided valuable insight in global Achilles tendon mechanics, but limitations with the technique used remain. Furthermore, given the global approach evaluating muscle-tendon junction to insertion, regional differences in tendon mechanical properties might be overlooked. However, recent advancements in the field of ultrasound imaging in combination with speckle tracking have made an intratendinous evaluation possible...

BACKGROUND: The antiphospholipid syndrome (APS) is defined by simultaneous presence of vascular clinical events and antiphospholipid antibodies (aPL). The aPL considered as diagnostics are lupus anticoagulant and antibodies anticardiolipin (aCL) and anti-ß2 glycoprotein-I (aB2GP1). During recent years, IgA aB2GP1 antibodies have been associated with thrombotic events both in patients positive, and mainly negative for other aPL, however its value as a pro-thrombotic risk-factor in asymptomatic patients has not been well defined...

Carotid artery atherosclerosis remains one of the major causes of stroke. The efficacy of carotid artery recanalization has already been established and is considered significant for symptomatic stenosis >70% and moderate for stenosis between 50-69 %. Regarding asymptomatic stenosis, carotid artery recanalization should be reserved for carefully selected patients with a stenosis between 70-90 % and an estimated procedural risk at less than 3 %. Two therapeutic options are currently available : angioplasty with stent placement and endarterectomy...

Toxocariasis is a zoonotic disease that occurs when humans are infected by the parasites Toxocara canis or Toxocara cati. Toxocariasis is highly prevalent in tropical areas, but can also be found in industrialized countries, particularly in rural areas. Clinical presentation can range from asymptomatic infection to more severe disease. Diagnosis of toxocariasis is based on suggestive clinical findings, eosinophilia and a positive serological testing. Albendazole represents the first-line treatment, associated with corticosteroids in case of severe disease...

Vascular wilt caused by Verticillium dahliae is a destructive disease that represents a chronic economic problem on crop production worldwide. In this work we characterized two new regulators of pathogenicity in this species. Vph1 (VDAG_06555) was identified in a candidate gene approach as a putative homolog of the transcription factor Ste12. Vhb1 (VDAG_08786), identified in a forward genetics approach, is similar to the homeobox transcription factor Htf1, reported as a regulator of conidiogenesis in several fungi...

Multimodal imaging is commonly used in the management of patients with cancer. Imaging plays pivotal roles in the diagnosis, initial staging, treatment response assessment, restaging after treatment and the prognosis of many cancers. Indeed, it is difficult to imagine modern precision cancer care without the use of multimodal molecular imaging, which is advancing at a rapid pace with innovative developments in imaging sciences and an improved understanding of the complex biology of cancer. Cancer therapy often leads to undesirable toxicity, which can range from an asymptomatic subclinical state to severe end organ damage and even death...

Baylisascaris procyonis (raccoon roundworm) infection is common in raccoons and can cause devastating pathology in other animals, including humans. Limited information is available on the frequency of asymptomatic human infection. We tested 150 adults from California, USA, for B. procyonis antibodies; 11 were seropositive, suggesting that subclinical infection does occur.

REVIEW
Ryan C Owen, Benjamin J McCormick, Bradley D Figler, Robert M Coward
A dilation of the pampiniform venous plexus in the scrotum above the testicle, called a varicocele, affects approximately 15% of the general male population. While the majority is asymptomatic, pain results in up to 10% of cases of varicoceles. The pain associated with varicoceles is typically mild and is described as heavy, achy, or dull-and is usually isolated to the testicle or spermatic cord. Guidelines clearly recommend varicocele repair in males with varicoceles, infertility, and an abnormal semen analysis...

Myxoma is the most common primary cardiac tumor and is usually located in the left atrium. Clinical manifestation relies in large part on the size, location, and architecture of the tumor. There are many reports in the literature of cardiac myxomas causing syncope, embolism, even myocardial infarction. We present a rare case of a patient who underwent urgent surgical resection of a large left atrial myxoma mimicking mitral stenosis. The postoperative course of the patient was uncomplicated. One year after surgery, the patient is asymptomatic and disease-free...

This study evaluated the circulating levels of serum symmetric dimethylarginine (SDMA) in 12 dogs with different severities of heartworm disease (HWD) and assessed the biochemical renal markers (blood urea nitrogen, creatinine). Dogs were classified into 2 groups based on the severity of clinical signs. Group A - asymptomatic to mild clinical signs, group B - moderate to severe clinical signs. The serum SDMA levels were higher in dogs in group B. Although the serum SDMA levels in dogs in group A were also higher than those of the control dogs, the difference was not statistically significant...

Following the 2013-14 outbreak in French Polynesia, the Zika virus (ZIKV) epidemic spread widely to many countries where Aedes Aegypti as the main transmitting vector is endemic. The lack of a second wave of ZIKV infection in most affected regions may suggest that a sufficiently high level of herd immunity was reached during the first wave. We developed an agent-based transmission model to investigate the role of asymptomatic infection on the likelihood of observing a second wave, while accounting for its relative transmissibility...

Pediatric tuberculosis (TB) is challenging to diagnose, confirmed by growth of Mycobacterium tuberculosis at best in 40% of cases. The WHO has assigned high priority to the development of non-sputum diagnostic tools. We therefore sought to identify transcriptional signatures in whole blood of Indian children, capable of discriminating intra-thoracic TB disease from other symptomatic illnesses. We investigated the expression of 198 genes in a training set, comprising 47 TB cases (19 definite/28 probable) and 36 asymptomatic household controls, and identified a 7- and a 10-transcript signature, both including NOD2, GBP5, IFITM1/3, KIF1B and TNIP1...

INTRODUCTION    The corrective effect of carotid endarterectomy (CEA) on disturbed ophthalmic artery flow in patients with a significant internal carotid artery stenosis (ICAS) presenting with ocular ischemic syndrome (i.e., symptomatic patients) is well established. However, no clear evidence exists regarding the efficacy of CEA for improvement of neuro-retinal function in patients without symptoms of ocular ischemic syndrome. OBJECTIVES    We determined the effects of CEA on retinal function in asymptomatic patients with hemodynamically significant internal carotid artery stenosis...

We previously reported that the T-cell receptor (TCR) repertoire of HTLV-I Tax301-309-specific CD8(+) cytotoxic T-cells (Tax-CTLs) was highly restricted and a particular amino acid sequence motif, "PDR", was conserved among HLA-A*24:02(+) ATL patients who have undergone allogeneic hematopoietic cell transplantation (allo-HSCT). Furthermore, we found that donor-derived PDR+CTLs selectively expanded in ATL long-term HSCT survivors with strong CTL activity against HTLV-I. On the other hand, the TCR repertoires in Tax-CTL of asymptomatic HTLV-I carriers (ACs) remain unclear...
