    Acetyl-L-carnitine (ALC) has shown a neuroprotective effect in patients with peripheral neuropathies of different etiologies. Preclinical studies demonstrated a central anti-nociceptive action, both in neuropathic and nociceptive pain models. The present review aims to provide the knowledge on the efficacy of ALC in patients with painful peripheral neuropathy, based on the evidence. Consistent with the PRISMA statement, authors searched PubMed, Embase and the Cochrane Database of Systematic Reviews for relevant papers, including those issued before April 2018. Two authors independently selected studies for inclusion and data extraction: only trials including patients with a diagnosis of peripheral neuropathy and involving at least 10 patients were considered for the purposes of this review. Fourteen clinical trials were revised, to provide the level of evidence for neuropathy. To assess the global efficacy of ALC in painful peripheral neuropathy, a meta-analysis of four randomized controlled trials was performed. Mean difference in pain reduction as measured on a 10-cm VAS, and 95% CIs were used for pooling continuous data from each trial. Four randomized controlled trials tested ALC in patients with neuropathy secondary to diabetes and to antiretroviral therapy for HIV. Compared to placebo, ALC produced a significant pain reduction equal to 20.2% (95% CI: 8.3%-32.1%, P<0.0001) with respect to baseline. Clinical trials also showed beneficial effects on nerve conduction parameters and nerve fiber regeneration, with a good safety profile. These data indicate that ALC provides an effective and safe treatment in patients with painful peripheral neuropathy. We recommend further studies to assess the optimal dose and duration of the therapeutic effect (also after treatment withdrawal)

    Ultrasound findings of ruptured Peyronie's plaque: Case report and review of the literature

    Get PDF
    We present here a rare case of rupture of tunica albuginea and corpus cavernosum, in the site of a Peyronie's plaque, which happened in a 61- year-old man during a vacuum cleaner masturbation. Ultrasound study showed an irregular hyperechoic defect at the cavernosal rupture site in correspondence of the Peyronie's plaque. The hematoma was evacuated, partially plaque excised, and the tear repaired. Ultrasonography is an ideal technique for evaluating patients with penile trauma and can be routinely used in an emergency. It is a non-invasive method that gives faster results than cavernosography and Magnetic Resonance Imaging

    Pseudoaneurysm with arteriovenous fistula of the prostate after pelvic trauma: Ultrasound imaging

    Get PDF
    Pseudoaneurysm (PA) associated with an arteriovenous fistula (AVF) of the internal pudendal artery branches are very uncommon. We report a case of post-traumatic PA with AVF connected to Santorini plexus. Diagnosis was made with trans-rectal ultrasound (TRUS) after recurrent hematuria. TRUS reported a 1.7 × 1.4 × 1.5 cm anechoic area, on anterior prostate apex close to Santorini plexus. The use of color Doppler in this area revealed high flow velocity that was indicative for AVF. The feeding artery was a distal branch of the left pudenda artery. After selective embolization was observed complete occlusion of the feeding branches and disappearance of PA with AVF. Prostate PA with concomitant symptomatic AVF detected with TRUS has not yet described in literature after pelvic trauma and represents complex diagnostic challenges. This case report suggests that the use of TURS and color Doppler can provide an important diagnostic and follow-up to address the clinical suspicion of occult vascular injuries using a noninvasive approach

    Updates on Laboratory Evaluation of Feline Cardiac Diseases

    Laboratory tests can be altered in cardiovascular diseases and the investigation of specific tests or biomarkers may provide additional information about myocardial damage. Traditional laboratory tests, such as cell blood count, serum biochemistry, and coagulation, can be useful in investigating patients, but are not specific. However, markers like Troponin and Natriuretic Peptides may possibly furnish further data on myocardium damage and can be used in both studying and monitoring cats with cardiac disease. Moreover, the evaluation of the thyroid profile is very important as hyperthyroid cats concomitant cardiovascular diseases are very common and they can also be a direct consequence of endocrinopathy. The purpose of this manuscript is to provide the widest possible overview of what is present in the literature about the feline clinical pathology of heart diseases through a rational division of the main alterations of traditional tests and biomarkers

    Bradykinesia and dystonia

    Get PDF
    Background: Bradykinesia has been reported in patients with dystonia. Despite this, the pathophysiological mechanisms of bradykinesia in dystonia remain largely unknown. Methods: We here performed a comprehensive literature search and reviewed clinical and experimental studies on bradykinesia in patients with dystonia. Results: Many studies have documented the presence of bradykinesia in patients with idiopathic and inherited isolated dystonia, regardless of the presence of parkinsonism. In addition, bradykinesia has been observed as a side effect in dystonic patients who have undergone deep brain stimulation, in those with functional dystonia as well as in those with combined dystonia, e.g., dystonia-parkinsonism. These clinical and experimental findings support the hypothesis that dysfunction in a brain network involving the basal ganglia, primary sensorimotor cortex, and cerebellum may play a key role in the pathophysiology of both bradykinesia and dystonia. Conclusion: Bradykinesia is frequently observed in dystonia. We may gain insights into the pathophysiological underpinnings of two distinct movement disorders by investigating this issue. Furthermore, a deeper understanding of bradykinesia in dystonia may have terminological implications in this field

    Adult primary paratesticular mesenchymal tumors with emphasis on a case presentation and discussion of spermatic cord leiomyosarcoma

    Get PDF
    Background: The aim of this report is related to adult primary paratesticular mesenchymal tumors with emphasis on a case presentation and discussion of the spermatic cord leiomyosarcoma. Primary paratesticular tumors are rare, only accounting for 7% to 10% of all intrascrotal tumors. In adults, more than 75% of these lesions arise from the spermatic cord, 20% being leiomyosarcoma. Tumor grade, stage, histologic type, and lymph node involvement are independently predictive of prognosis. Findings: The case report concerns a 81-year-old man presented with a 3-year history of painless lump in the right hemiscrotum. Scrotal examination demonstrated a 5.1-cm, firm-to-hard mass attached to the spermatic cord. Scrotal ultrasound scan revealed a heterogeneous mass separate from the testis. He was treated with an radical orchi-funicolectomy. Histologically the lesion is composed of spindled cells with often elongated, blunt-ended nuclei and variably eosinophilic cytoplasm. Areas with pleomorphic morphology are present. The level of mitotic activity is equal to 3/10 HPF in the areas with spindle cell morphology and to 12/10 HPF in the areas with pleomorphic morphology. The final diagnosis was that a leiomyosarcoma of the spermatic cord, with grade 1 and grade 2 areas, stage pT2b cN0 and cM0. The patient has been followed up for 3 months with CT scans and shows no signs of recurrence. Conclusions: Spermatic cord leiomyosarcoma, although rare, should be one of the first differential diagnoses for a firm-to-hard lump in the cord. Apart from radical orchi-funicolectomy, there has been added benefit of adjuvant radiotherapy to prevent any loco-regional lymph node recurrenc

    Objective: The aim of the study is to make a review of the literature about bladder malakoplakia. Material and Methods: We searched articles on the PUBMED web-literature database with the following keywords: “vesical malakoplakia” and “bladder malakoplakia”. In the literature we found 254 articles. At final we have excluded 219 articles, including in our study only 35 articles. Results: The overall average age found was 50.85 years. The average age of men was 43.22 years, while that of women was 53.37 years. 75% of the patient cases were women and 25% were men. Regarding comorbidities, in 5.55% of the cases were missing whereas 47.22% of the patients suffered from recurrent urinary tract infection (UTI) and 19.44% from immune system disorders. Urine culture was positive in 69.44% with E.coli being isolated in 92% of cases. Hydroureteronephrosis was present in 44.44% of the cases: left in 6.25% of cases, right in 18.75% and bilateral in 75%. The mean serum creatinine of patients with hydroureteronephrosis was 5.11 (1-21) mg/dl. The most frequent site of the lesion was the vesicoureteral junction (VUJ) (42.31%), followed by the trigone (38.46%). 30.56% of patients were treated with antibiotic and surgery (transurethral resection of bladder, partial or radical cystectomy), less frequent options were antibiotics alone and surgery alone. The recurrence rate was 15%.Conclusions: Malakoplakia is a disorder usually related to other affections, like UTI and immunodepression, and it seem to be caused by an abnormal macrophage function. In almost half of the described cases of isolated bladder malakoplakia, hydroureteronephrosis and renal failure were present.Treatment is not standardized, but both medical and surgical therapies are effective to avoid recurrence.</jats:p
