Immunogenicity and safety of an inactivated hepatitis A vaccine in anti-HIV positive and negative homosexual men.
1995
The immunogenicity, reactogenicity, and safety of an inactivated hepatitis A vaccine were assessed in anti-HIV positive homosexual men. Fourteen anti-HIV positive (group 1) and 20 anti-HIV negative (group 2) men received vaccine (containing 720 ELISA units of hepatitis A antigen per dose) intramuscularly at 0, 1, and 6 months. Twelve unvaccinated anti-HIV positive men (group 3) were included as controls to evaluate disease progression. Seroconversion (anti-hepatitis V virus (HAV ⩾20 mlU/ml) was higher in group 2 than group 1 at months 2 (100% vs. 73%) and 7 (l00%vs. 77%). Group 2 had higher antibody titres than group 1 at months 1 (201 vs. 92 mlU/ml) and 7 (1, 687 vs. 636 mlU/ml). The decli…
Long-term CD4+ T-cell count evolution after switching from regimens including HIV nucleoside reverse transcriptase inhibitors (NRTI) plus protease in…
2011
Abstract Background Data regarding CD4+ recovery after switching from protease inhibitor (PI)-based regimens to regimens not containing PI are scarce. Methods Subjects with virological success on first-PI-regimens who switched to NNRTI therapy (NNRTI group) or to nucleoside reverse transcriptase (NRTI)-only (NRTI group) were studied. The effect of the switch on the ongoing CD4+ trend was assessed by two-phase linear regression (TPLR), allowing us to evaluate whether a change in the CD4+ trend (hinge) occurred and the time of its occurrence. Furthermore, we described the evolution of the frequencies in CD4-count classes across four relevant time-points (baseline, before and immediately after…
Prophylactic Thyroidectomy in 75 Children and Adolescents with Hereditary Medullary Thyroid Carcinoma: German and Austrian Experience
1998
When mutations of the RETproto-oncogene were found in 1993 to account for hereditary medullary thyroid carcinoma (MTC), surgeons obtained the opportunity to operate on patients prophylactically (i. e., at a clinically asymptomatic stage). Whether this approach is justified, and, if so, when and to which extent surgery should be performed remained to be clarified. A questionnaire was sent to all surgical departments in Germany and Austria. All of the patients who fulfilled the following criteria were enrolled: (1) preoperatively proved RET mutation; (2) age/= 20 years, (3) clinically asymptomatic thyroid C cell disease; and (4) TNM classification pT0-1/pNX/pN0-1/M0. Seventy-five patients wer…
Validity of Laparoscopic Staging to Avoid Adjuvant Chemoradiation following Radical Surgery in Patients with Early Cervical Cancer
2012
<b><i>Purpose:</i></b> To determine the rate of unavoidable adjuvant chemoradiation (RCTX) due to histologic results after radical surgery in patients with early cervical cancer. <b><i>Patients and Methods:</i></b> Between May 2004 and July 2011, 448 consecutive patients diagnosed with invasive cervical cancer stage IA1 L1 to IIA underwent laparoscopic staging at the Department of Gynecology and Gynecologic Oncology at Charité Berlin. Only in patients without lymph node metastases (n = 394) on frozen section, radical operation was continued either by laparoscopic radical hysterectomy (n = 228) or by radical vaginal trachelectomy (n = 166). The…
Omitting axillary lymph node dissection after positive sentinel lymph node in the post-Z0011 era: Compliance with NCCN and ASCO clinical guidelines a…
2021
Summary Purpose In the ACOSOG Z0011 trial, patients with primary breast cancer and 1–2 tumor-involved sentinel lymph nodes (SLNs) undergoing breast-conserving surgery had no oncological outcome benefit after axillary lymph node dissection (ALND), despite a relevant rate of non-SLN metastases of 27%. According to the St Gallen expert consensus, and NCCN and ASCO clinical guidelines, ALND may be avoided in patients who meet all ACOSOG Z0011 inclusion criteria. This recommendation can also be extended to patients undergoing mastectomy, with 1 or 2 positive SLNs and an indication for chest wall radiation, in whom axillary radiotherapy can be proposed as an alternative to completion ALND. The ai…
Axillary Nodal Burden in Breast Cancer Patients With Pre-operative Fine Needle Aspiration-proven Positive Lymph Nodes Compared to Those With Positive…
2019
BACKGROUND/AIM: Recent years have seen a considerable shift to a more conservative management of the axilla in patients with positive axillary sentinel lymph nodes. The aim of this study was to determine whether some breast cancer patients with a preoperative ultrasound-guided needle aspiration biopsy proven positive node could potentially be spared an axillary lymph node dissection according to the ACOSOG Z0011 trial criteria. PATIENTS AND METHODS: A retrospective review was performed involving 623 breast cancer patients who underwent axillary lymph node dissection after either ultrasound-guided needle aspiration biopsy proven positive node or sentinel lymph node biopsy. RESULTS: Patients …
Capacity assessment for provision of quality sexual reproductive health and HIV-integrated services in Karamoja, Uganda
2020
Introduction: Sexual and reproductive health (SRH) and Human Immunodeficiency Virus (HIV) are crucial global health issues. Uganda continues to sustain a huge burden of HIV and AIDS.
 Methods: A cross-sectional health facility-based assessment was performed in November and December 2016 in Karamoja Region, northern Uganda. All the 126 health facilities (HFs) in Karamoja, including 5 hospitals and 121 Health Centers (HCs), covering 51 sub-counties of the 7 districts were assessed. We assessed the capacity of a) leadership and governance, b) human resource, c) service delivery, d) SRH and HIV service integration and e) users satisfaction and perceptions.
 Results: 64% of the establi…
Lymphocyte subpopulations in solvent-exposed workers.
1986
To estimate the cellular immune response of workers highly exposed to mixtures of organic solvents, subpopulations of peripheral blood lymphocytes (PBLs) were analyzed. For this, the PBLs of nine floorers (aged 25–58 years, exposure time 8–35 years) were subsequently labelled with monoclonal antibodies OKT 4, OKT 8, OKT 11, anti-Leu 7 and anti-Leu 12. Analysis was made by a FACS IV cell sorter (Becton-Dickinson, USA). The control group consisted of matched pairs of healthy donors. In the exposed group we found a decrease in the OKT 11 (all) T cell fraction, a decrease in the OKT 4 helper cells, an increase in the anti-Leu 7 positive cells, mostly natural killer cells, an important increase …
Immunohistochemical Investigation of Metastasis-Related Chemokines in Deep-Infiltrating Endometriosis and Compromised Pelvic Sentinel Lymph Nodes
2015
Endometriosis is a prevalent benign disease, despite sharing several similarities with malignancies, such as the possibility of lymphatic spread. In malignancies, chemokines play a sovereign role in the process of metastasis. Metastasis-related chemokine axes have not yet been assessed in deep-infiltrating endometriosis (DIE), and this investigation was the aim of our study. The expression of these chemokines was investigated by immunohistochemistry in rectovaginal DIE lesions and in matched pelvic sentinel lymph nodes (PSLNs) of patients with endometriosis (n = 27), and their expression in the eutopic endometrium (EE) of endometriosis-free women (n = 20) was used as controls. Their stainin…
Use of needles and syringes in Miami and Valencia: observations of high and low availability.
2000
Two studies engaged in gathering data on injecting drug users (IDUs) employed supplementary resources to enhance their ethnographic components and compare patterns of use of needles/syringes (n/s) in two geographically similar but culturally distinct cities. Despite its policy of making n/s highly available at fair prices, Valencia, Spain, has markedly higher rates of HIV seroprevalence among its IDUs than does Miami, Florida, where possession of n/s is illegal. Ethnographically based models that track IDUs through choices of injection venues help to explain this difference. Inability of IDUs in Valencia to use their own domiciles as venues for injection contrasts sharply with problems of M…
