Human immunodeficiency virus (HIV)-associated progressive multifocal leukoencephalopathy (PML) remains a relevant clinical problem even in the era of highly active antiretroviral therapy (HAART). Aims of the study were to analyze clinical and treatment-related features and the survival probability of PML patients observed within the Italian Registry Investigative Neuro AIDS (IRINA) during a 29-month period of HAART. Intravenous drug use, the presence of focal signs, and the involvement of white matter at neuroradiology increased the risk of having PML. A reduced probability of PML was observed when meningeal signs were reported. Patients starting HAART at PML diagnosis and previously naïve for antiretrovirals showed significantly higher 1-year probability of survival (.58), compared to those continuing HAART (.24), or never receiving HAART (.00). Higher CD4 cell count were associated with a higher survival probability (.45). At multivariate analysis, a younger age, higher CD4, starting HAART at PML diagnosis, the absence of previous acquired immunodeficiency syndrome (AIDS)-defining events, and the absence of a severe neurologic impairment were all associated with a reduced hazard of death. The use of cidofovir showed a trend towards a reduced risk of death. 相似文献

The purpose of this study was to evaluate the outcome of tension-free vaginal tape (TVT) procedure in women with urodynamic stress incontinence diagnosed as having intrinsic sphincteric deficiency (ISD). The combination of a maximal urethral closure pressure <20 cm H2O and a Valsalva leak point pressure <60 cm H2O was considered as diagnostic of ISD. Subjects with detrusor overactivity on preoperative urodynamics were excluded. A total of 35 patients with both low closure pressure and leak point pressure were enrolled. Bladder perforation occurred in three (8.6%) cases. Postoperative urinary voiding difficulties occurred in nine (25.7%) women. Two patients underwent surgical detension of the tape, with complete resolution of urinary retention and no relapse of incontinence. Women with postoperative voiding dysfunction had a significantly lower detrusorial pressure at the peak flow on preoperative urodynamics compared to those who voided efficiently after TVT. The mean (range) follow-up time was 12.5 months (3–36). The objective cure rate for stress incontinence was 91.4%. Two of the three (66%) patients in whom the TVT procedure failed had a fixed urethra. De novo urge incontinence was found in five (14.3%) patients. 相似文献

Hepatocyte growth factor (HGF), a stimulator of angiogenesis and cell migration, regulates the growth of a wide variety of
cells by binding to its high-affinity receptor met and is involved in the growth and aggressiveness of several tumors. In
this study we investigated the expression of HGF and met in normal endocrine cells and related neoplasms of the gut and pancreas
to verify their possible role in tumor pathogenesis, growth, and aggressiveness. Normal tissues and 60 different endocrine
tumors were immunostained using specific antibodies directed against HGF, met, and various hormones. HGF immunoreactivity
(IR) was found in antroduodenal G cells, rectal enterochromaffin (EC) cells, and pancreatic A and B cells, whereas met IR
was detected in antral EC and G cells, and in pancreatic B cells; 46 of 60 tumors examined were positive for HGF, and they
were mainly represented by ECL-, EC-, and L-cell neoplasms. met IR was identified in 50/60 tumors of various phenotypes. HGF
and met coexpression was found in 42/60 cases, most of which were represented by EC-cell tumors. HGF/met coexpression was
significantly more frequent in ileolonic EC-cell tumors, which in the majority of cases were malignant, than in appendiceal
EC-cell tumors, which were all benign. Our results demonstrated, for the first time, that HGF and met are specifically distributed
in normal gut and pancreatic endocrine cells and, in addition, suggest that HGF and met may be implicated as autocrine/paracrine
factors regulating the growth of gastroenteropancreatic endocrine tumors, mainly of ileocolonic EC-cell carcinoids. 相似文献

OBJECTIVE: To compare the surgicopathologic outcome of total laparoscopic radical hysterectomy (LRH) with that of abdominal radical hysterectomy (ARH) for the treatment of early-stage cervical cancer. METHODS: Radical hysterectomy specimens of sequential patients undergoing LRH (N=50) were compared with those of historical controls selected from consecutive women who have had conventional ARH (N=48), and who met the same criteria for eligibility as the cases. To evaluate the extent of parametrial resection, parametrial tissues were systematically measured at their widest dimensions before tissue processing. RESULTS: No difference was found in demographics, histologic type, tumor stage and grade between the two groups. The parametrial width was similar between LRH and ARH in both type II (right parametrium: 2.4 cm (1-3) vs. 2.3 (1.8-4.0), p=0.28; left parametrium: 2.3 cm (1.8-4) vs. 2.2 (1.2-3.0), p=0.54) and type III radical hysterectomy (right parametrium: 3.8 cm (2.3-6.5) vs. 3.4 (1.7-7.0), p=0.59; left parametrium: 3.6 cm (2-6) vs. 3.5 (1.5-6.5), p=0.82). There were no significant differences between the two groups with regard to lymph nodes yield and likelihood of identifying positive margins or metastatic disease. CONCLUSION: Our results suggest that laparoscopically managed patients with cervical cancer undergo a similar extent of surgery as those treated with the traditional ARH, as judged by objective pathologic criteria. 相似文献

The aim of this study was to assess the efficacy of tolterodine in women with overactive bladder (OAB) and concomitant anterior vaginal prolapse. In this prospective study, 235 consecutive women with OAB symptoms and urodynamic diagnosis of detrusor overactivity who either had no prolapse or had pure anterior vaginal prolapse were included: 184 women (group 1) had no prolapse and 51 women (group 2) had anterior prolapse greater than and equal to stage IIa. Tolterodine 4 mg slow release once a day was prescribed. After 12 weeks, women were reassessed using a 3-point scale (no change, improvement and cured). A total of 158 (85.9%) women in group 1 and 31 (60.8%) women in group 2 reported improvement or cure ( P = 0.0002). Women with OAB and significant anterior vaginal prolapse should be informed of a reduced efficacy of antimuscarinics in treating their urinary symptoms. 相似文献

Unilateral papillitis caused by Treponema pallidum was found in an immunocompetent homosexual patient with severe vision loss who had received previous antibiotics treatment. Syphilis-related ocular manifestation is more common in the early stages of the disease and it can be associated with a central nervous system localization. In this patient, neurosyphilis was diagnosed on the basis of clinical and laboratory findings. Optical examination revealed unilateral papillitis in the left eye and no relative afferent pupillary defects. The patient underwent visual field examinations with conventional perimetry using the 30-2 program of the Humphrey Visual Field Analyzer, which indicated a blind spot enlargement in the left eye. Optical coherence tomography, visual evoked potentials (VEP), and fluorescein angiograms revealed inflammation of the optic nerve head with edematous and blurred margins. A reactive T. pallidum hemagglutination assay with low rapid plasma reagin (RPR) serum titer was performed; an HIV antibody test and MRI of the orbits and head with contrast gave negative results. Resolution of the ocular inflammation after intravenous penicillin treatment was obtained. The reported case illustrates the importance of early recognition of this treatable disease. The rise of syphilis, especially in urban areas, necessitates a high level of suspicion when dealing with patients with intraocular inflammation of unknown origin. Lues serology should be incorporated into routine laboratory diagnostics to aid in the detection of such cases. Considering the re-emergence of syphilis, screening of migrants from countries with high syphilis seroprevalences should be recommended. 相似文献

Mutations in AarF domain‐containing kinase 3 (ADCK3) are responsible for the most frequent form of hereditary coenzyme Q10 (CoQ10) deficiency (Q10 deficiency‐4), which is mainly associated with autosomal recessive cerebellar ataxia type 2 (ARCA2). Clinical presentation is characterized by a variable degree of cerebellar atrophy and a broad spectrum of associated symptoms, including muscular involvement, movement disorders, neurosensory loss, cognitive impairment, psychiatric symptoms and epilepsy. In this report, we describe, for the first time, a case of photoparoxysmal response in a female patient with a mutation in ADCK3. Disease onset occurred in early childhood with gait ataxia, and mild‐to‐moderate degeneration. Seizures appeared at eight years and six months, occurring only during sleep. Photoparoxysmal response was observed at 14 years, almost concomitant with the genetic diagnosis (c.901C>T;c.589‐3C>G) and the start of CoQ10 oral supplementation. A year later, disease progression slowed down, and photosensitivity was attenuated. A review of the literature is provided focusing on epileptic features of ADCK3‐related disease as well as the physiopathology of photoparoxysmal response and supposed cerebellar involvement in photosensitivity. Moreover, the potential role of CoQ10 oral supplementation is discussed. Prospective studies on larger populations are needed to further understand these data. 相似文献
