    <p>Abstract</p> <p>Background</p> <p>Spontaneous spinal epidural hematoma is a relatively rare but potentially disabling disease. Prompt timely surgical management may promote recovery even in severe cases.</p> <p>Case presentation</p> <p>We report a 34-year-old man with a 2-hour history of sudden severe back pain, followed by weakness and numbness over the bilateral lower limbs, progressing to intense paraparesis and anesthesia. A spinal magnetic resonance imaging scan was performed and revealed an anterior epidural hematoma of the thoracic spine. He underwent an emergency decompression laminectomy of the thoracic spine and hematoma evacuation. Just after surgery, his lower extremity movements improved. After 1 week, there was no residual weakness and ambulation without assistance was resumed, with residual paresthesia on the plantar face of both feet. After 5 months, no residual symptoms persisted.</p> <p>Conclusions</p> <p>The diagnosis of spontaneous spinal epidural hematoma must be kept in mind in cases of sudden back pain with symptoms of spinal cord compression. Early recognition, accurate diagnosis and prompt surgical treatment may result in significant improvement even in severe cases.</p

    Evolution of Anolis Lizard Dewlap Diversity

    BACKGROUND: The dewlaps of Anolis lizards provide a classic example of a complex signaling system whose function and evolution is poorly understood. Dewlaps are flaps of skin beneath the chin that are extended and combined with head and body movements for visual signals and displays. They exhibit extensive morphological variation and are one of two cladistic features uniting anoles, yet little is known regarding their function and evolution. We quantified the diversity of anole dewlaps, investigated whether dewlap morphology was informative regarding phylogenetic relationships, and tested two separate hypotheses: (A) similar Anolis habitat specialists possess similar dewlap configurations (Ecomorph Convergence hypothesis), and (B) sympatric species differ in their dewlap morphologies to a greater extent than expected by chance (Species Recognition hypothesis). METHODOLOGY/PRINCIPAL FINDINGS: We found that dewlap configurations (sizes, patterns and colors) exhibit substantial diversity, but that most are easily categorized into six patterns that incorporate one to three of 13 recognizable colors. Dewlap morphology is not phylogenetically informative and, like other features of anoles, exhibits convergence in configurations. We found no support for the Ecomorph Convergence hypothesis; species using the same structural habitat were no more similar in dewlap configuration than expected by chance. With one exception, all sympatric species in four communities differ in dewlap configuration. However, this provides only weak support for the Species Recognition hypothesis because, due to the great diversity in dewlap configurations observed across each island, few cases of sympatric species with identical dewlaps would be expected to co-occur by chance alone. CONCLUSIONS/SIGNIFICANCE: Despite previous thought, most dewlaps exhibit easily characterizable patterns and colorations. Nevertheless, dewlap variation is extensive and explanations for the origin and evolution of this diversity are lacking. Our data do not support two hypothesized explanations for this diversity, but others such as sexual selection remain to be tested

    Aim: Pelvic floor muscle training (PFMT) is classified with a level 1 evidence and a grade A recommendation, but long term effects have not been studied thoroughly. This study aims at assessing the long-term effectiveness of perineal rehabilitation on patients with mild prolapse and pure stress urinary incontinence (IUS) symptoms. Methods: Retrospective observational study on 49 patients examined at the beginning of the observation and 60 months after receiving biofeedback assisted PFMT. We created two groups. Group A: 27 women with mild symptoms of prolapse and pure mild IUS; Group B: 22 symptomatic patients postsurgery. We considered as therapeutic success a 50% general reduction of the symptoms experienced by the patients in terms of reduction of leakage episodes, number of pads used, strength and endurance of the pubococcygeus muscle and initial prolapse signs/symptoms. Results: Group A (follow-up 60 months): Reduction of prolapse symptoms: cured/much improved: 65% (17 patients); worse: 22.4%(6 patients); unchanged: 18.5% (5 patients); reduction of urinary symptoms: cured/much improved: 59.3% (16 patients); surgery: 40.7% (11 patients); group B (follow-up 60 months); cured: 55.5% (12 patients); much improved: 44% (10 patients) Conclusion: In conclusion, as for the treatment of menopausal patients with symptoms of mild disorders of the urinary/genital system, excellent results were reported in women underwent rehabilitation, as a first approach or after failed TVT-O

    Persistent papillomavirus type-31 and type-45 infections predict the progression to squamous intraepithelial lesion

    Objective: Human papillomavirus (HPV) has been recognized as the major etiologic agent of cervical squamous cell carcinoma. However, it has been demonstrated that HPV infection is usually a self-limited process and does not lead to significant epithelial lesions or cancer. Recent data indicate that persistent high-risk HPV (HR-HPV) infections have a significantly increased risk of developing incident high-grade cervical intraepithelial neoplasia and cervical cancer. Our aim, therefore, was to assess whether there exist HPV genotypes whose persistence can be considered powerful surrogates of a progressive disease. We retrospectively selected all patients with a negative cytological diagnosis or with atypical squamous cells of undetermined significance, with a positive test for HR-HPV, different from HPV types 16 and 18, and assessed the significance of the risk of progression based on the persistence of the specific HR-HPV. Materials and methods: We retrospectively queried the database of our Colposcopy Clinic for all patients with a negative cytological diagnosis or with atypical squamous cells of undetermined significance and a positive test for HR-HPV, and we calculated the incidence of progression to lesions greater than or equal to low-grade squamous intraepithelial lesions after 6 months, according to the HPV type. Results: A progression rate of 48.27% was found in patients tested positive for HPV-31 (Group 1), 38.46% in patients tested positive for HPV-45 (Group 2), and 5.73% in patients tested positive for HPV types other than HPV-16, HPV-18, HPV-31, and HPV-45 (Group 3). Conclusion: Our data demonstrate that the persistence of HPV-31 and HPV-45 is strongly associated with the occurrence of squamous intraepithelial lesion
