Androgen dependence of hirsutism, acne, and alopecia in women: retrospective analysis of 228 patients investigated for hyperandrogenism.

Hirsutism, acne, alopecia, and oligo-amenorrhea are clinical expressions of hyperandrogenism, one of the most frequent endocrine disorders in women of reproductive age. Women referred to our endocrine clinics for skin symptoms of hyperandrogenism underwent a laboratory workup to evaluate hormone measurements and received antiandrogen therapy. We retrospectively analyzed the outcome of 228 consecutive patients investigated over 6 years.Patients with hirsutism had higher levels of androstenedione, dehydroepiandrosterone sulfate (DHEAS), and salivary testosterone; lower levels of sex hormone-binding globulin (SHBG); and a higher prevalence of oligo-amenorrhea than patients with alopecia, while patients with acne showed intermediate values. Hirsutism score correlated positively with androstenedione, DHEAS, and salivary testosterone, and correlated negatively with SHBG; salivary testosterone showed the highest correlation coefficient. Total testosterone was not significantly different among patients with hirsutism, alopecia, or acne, and did not significantly correlate with hirsutism score. Hirsutism and oligo-amenorrhea were the most sensitive symptoms of hyperandrogenism, and no androgenic parameter alone allowed us to identify all cases of hyperandrogenism.Patients of central European origin sought consultation with milder hirsutism scores than patients of southern European origin. There was, however, no difference in the clinical-biological correlation between these groups, arguing against differences in skin sensitivity to androgens.Polycystic ovary syndrome, defined as hyperandrogenism (hirsutism or elevated androgens) and oligo-amenorrhea, was diagnosed in 63 patients (27.6%), an underestimate compared with other reports that include systematic ovarian ultrasound studies. Neither pelvic ultrasound, used in a limited number of cases, nor the luteinizing hormone/follicle-stimulating hormone ratio helped to distinguish patients with polycystic ovary syndrome from the other diagnostic groups. These included hyperandrogenism (hirsutism or elevated androgens) and eumenorrhea (101 patients; 44.3%); normal androgens (acne or alopecia and eumenorrhea) (51 patients; 22.4%); isolated low SHBG (7 patients; 3.1%); nonclassical congenital adrenal hyperplasia (4 patients; 1.8% of total, 4.9% of patients undergoing cosyntropin stimulation tests); and ovarian tumor (2 patients; 0.9%).Ethinylestradiol and high-dose cyproterone acetate treatment lowered the hirsutism score to 53.5% of baseline at 1 year, and was also effective in treating acne and alopecia. The clinical benefit is ascribed to the peripheral antiandrogenic effect of cyproterone acetate as well as the hormone-suppressive effect of this combination. Salivary testosterone showed the most marked proportional decrease of all the androgens under treatment. Cost-effectiveness and tolerance of ethinylestradiol and high-dose cyproterone acetate compared well with other antiandrogenic drug therapies for hirsutism. The less potent therapy with spironolactone only, a peripheral antiandrogen without hormone-suppressive effect, was effective in treating isolated alopecia in patients with normal androgens.

Nilotinib compassionate use in advanced GIST : a retrospective analysis

Introduction: Tyrosine kinase inhibitors (TKI) have considerably improved outcome of patients with advanced GIST and extended overall survival to more than 5 years. Yet, the median progression-free survival is approximately 2 years with first-line imatinib and 24 weeks with second-line sunitinib, which calls for treatment alternatives. Nilotinib is a second-generation TKI with at least similar inhibitory activity as imatinib. A Phase I study has shown that nilotinib monotherapy has clinical activity in GIST. Methods: After failure of all available therapeutic options patients had access to nilotinib on a compassionate use (CU) programm. Nilotinib was started at a dose of 400 mg bid, with dose reduction to 400mg qd allowed in the case of toxicity. 94 pts were approved for nilotinib CU in 10 European countries. We herein present retrospective data of 42 pts from 5 European countries treated in 11 centers. Results: Median age at nilotinib treatment start was 59 years (median; range 24-79 y). 30 of 42 patients were male. Most pts had metastatic disease of gastric origin at initial diagnosis. KIT exon 11 mutations were most frequent. The median number of surgical resections was 1 (range 0-8). All pts had failed both imatinib and sunitinib before nilotinib, and few had also received additional investigational treatments. Nilotinib was well tolerated, and discontinued due to toxicity in 15% only. Median follow-up is 176 days (range 15-876 d). Nilotinib treatment duration is 75 days (median; range 3-727 d). Partial remission with nilotinib treatment was seen in 11% of pts. Median OS was 263 days (Kaplan-Meier). Conclusion: This is the largest series reported assessing efficacy of nilotinib for imatinib- and sunitinib-refractory GIST reported yet. Nilotinib displays significant clinical activity in this heavily pretreated group of pts. These results warrant further investigation of nilotinib in GIST, including its use in first or second-line treatment. Patient and data collection is ongoing, updated results will be presented.

Patients with AIDS-defining cancers are not universally screened for HIV: a 10-year retrospective analysis of HIV-testing practices in a Swiss university hospital.

OBJECTIVES: Kaposi's sarcoma (KS), invasive cervical carcinoma (ICC) and non-Hodgkin lymphoma (NHL) have been listed as AIDS-defining cancers (ADCs) by the Centers for Disease Control and Prevention since 1993. Despite this, HIV screening is not universally mentioned in ADC treatment guidelines. We examined screening practices at a tertiary centre serving a population where HIV seroprevalence is 0.4%. METHODS: Patients with KS, ICC, NHL and Hodgkin lymphoma (HL), treated at Lausanne University Hospital between January 2002 and July 2012, were studied retrospectively. HIV testing was considered part of the oncology work-up if performed between 90 days before and 90 days after the cancer diagnosis date. RESULTS: A total of 880 patients were examined: 10 with KS, 58 with ICC, 672 with NHL and 140 with HL. HIV testing rates were 100, 11, 60 and 59%, and HIV seroprevalence was 60, 1.7, 3.4 and 5%, respectively. Thirty-seven patients (4.2%) were HIV-positive, of whom eight (22%) were diagnosed at oncology work-up. All newly diagnosed patients had CD4 counts < 200 cells/μL and six (75%) had presented to a physician 12-236 weeks previously with conditions warranting HIV testing. CONCLUSIONS: In our institution, only patients with KS were universally screened. Screening rates for other cancers ranged from 11 to 60%. HIV seroprevalence was at least fourfold higher than the population average. As HIV-positive status impacts on cancer patient medical management, HIV screening should be included in oncology guidelines. Further, we recommend that opt-out screening should be adopted in all patients with ADCs and HL.

Retrospective analysis of stored dried blood spots from children with cystic fibrosis and matched controls to assess the performance of a proposed newborn screening protocol in Switzerland.

BACKGROUND: Newborn screening (NBS) for Cystic Fibrosis (CF) has been introduced in many countries, but there is no ideal protocol suitable for all countries. This retrospective study was conducted to evaluate whether the planned two step CF NBS with immunoreactive trypsinogen (IRT) and 7 CFTR mutations would have detected all clinically diagnosed children with CF in Switzerland. METHODS: IRT was measured using AutoDELFIA Neonatal IRT-Kit in stored NBS cards. RESULTS: Between 2006 and 2009, 66 children with CF were reported, 4 of which were excluded for various reasons (born in another country, NBS at 6 months, no informed consent). 98% (61/62) had significantly higher IRT compared to matched control group. There was one false negative IRT result in an asymptomatic child with atypical CF (normal pancreatic function and sweat test). CONCLUSIONS: All children but one with atypical CF would have been detected with the planned two step protocol.

Polypharmacy as predictor of drug cost, length of hospital stay and mortality rate in nursing homes : a retrospective analysis of pharmacy medication records

Background and objectives: Polypharmacy (PP) is a typical con-sequence of multiple chronic conditions in elderly patients. PP is commonly defined as the use of multiple concurrent drug therapies although a standard definition is not used. The aims of this study were to assess the PP rate among nursing home (NH) residents using the data of the pharmacy medication records and to investigate the threshold level of PP as predictor of drug cost, length of hospital stay and mortality rate

Sorafenib fourth-line treatment in imatinib-, sunitinib-, and nilotinib-resistant metastatic GIST : a retrospective analysis : 10564

Background: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors usually caused by mutations in the KIT or PDGFRA gene. Advanced disease generally cannot be cured by surgery nor by tyrosine kinase inhibitors (TKI), but TKIs have considerably improved outcome for patients (pts) with advanced GIST. Patients failing TKI treatment with imatinib (IM), sunitinib (SU) or nilotinib (NI) have a poor prognosis. Sorafenib is a multi kinase inhibitor that blocks not only receptor tyrosine kinases such as KIT, VEGFR and PDGFR but also serine/threonine kinases along the RAS/RAF/MEK/ERK pathway. Recently, clinical activity of sorafenib in third-line treatment in patients with GIST after IM and SU failure has been shown (Wiebe et al. ASCO 2008, #10502). Methods: We report herein preliminary data of 32 pts treated with sorafenib in nine European centers. Centers were selected based on their previous and known experience in GIST and reported all pts treated. Pts received sorafenib after failure of IM, SU and NI in fourth-line treatment. Baseline characteristics and treatment details have been retrieved via questionary. Results: Median age at sorafenib treatment start was 62 years (range 33-81 y), and the majority of pts were male (63 %). Primary tumor site was gastric or small intestine in 25% and 41% of pts, respectively. All pts had failed IM, SU, NI. 19 % of pts achieved partial remission and 44% disease stabilization. Approximately half of the pts had an improvement of symptoms and/or performance. Half of the pts were on treatment longer than 4 months (actuarial data) and 41% of pts continue to receive sorafenib. Median progression-free survival is 20 weeks and median overall survival 42 weeks (Kaplan-Meier), at a median follow-up of 22 weeks (range 3-54). Conclusions: This is the largest series assessing efficacy of sorafenib fourth-line treatment for IM, SU and NI refractory GIST reported yet. Sorafenib displays significant clinical activity in this heavily pretreated group of patients.

Clinical management and outcome of histologically verified adult brainstem gliomas in Switzerland: a retrospective analysis of 21 patients.

Because of low incidence, mixed study populations and paucity of clinical and histological data, the management of adult brainstem gliomas (BSGs) remains non-standardized. We here describe characteristics, treatment and outcome of patients with exclusively histologically confirmed adult BSGs. A retrospective chart review of adults (age >18 years) was conducted. BSG was defined as a glial tumor located in the midbrain, pons or medulla. Characteristics, management and outcome were analyzed. Twenty one patients (17 males; median age 41 years) were diagnosed between 2004 and 2012 by biopsy (n = 15), partial (n = 4) or complete resection (n = 2). Diagnoses were glioblastoma (WHO grade IV, n = 6), anaplastic astrocytoma (WHO grade III, n = 7), diffuse astrocytoma (WHO grade II, n = 6) and pilocytic astrocytoma (WHO grade I, n = 2). Diffuse gliomas were mainly located in the pons and frequently showed MRI contrast enhancement. Endophytic growth was common (16 vs. 5). Postoperative therapy in low-grade (WHO grade I/II) and high-grade gliomas (WHO grade III/IV) consisted of radiotherapy alone (three in each group), radiochemotherapy (2 vs. 6), chemotherapy alone (0 vs. 2) or no postoperative therapy (3 vs. 1). Median PFS (24.1 vs. 5.8 months; log-rank, p = 0.009) and mOS (30.5 vs. 11.5 months; log-rank, p = 0.028) was significantly better in WHO grade II than in WHO grade III/IV tumors. Second-line therapy considerably varied. Histologically verification of adult BSGs is feasible and has an impact on postoperative treatment. Low-grade gliomas can simple be followed or treated with radiotherapy alone. Radiochemotherapy with temozolomide can safely be prescribed for high-grade gliomas without additional CNS toxicities.

Retrospective analysis of complications of immunosuppressive therapies (steroidsand immunosuppressive therapies) in pediatric uveitis

Purpose¦The purpose of this study is to analyze the incidence rate of side effects occurring during systemic therapy (corticosteroids, methotrexate, azathioprine, cyclosporine A or biologic agents) of auto-immune uveitis.¦Material and methods¦Retrospective study including 23 / 71 patients aged between 0-16 years old presenting with a chronic non-infectious uveitis. All children were treated in the Jules-Gonin Eye Hospital and paediatric rheumatology unit of the CHUV (Centre Hospitalier Universitaire Vaudois) between January 2000 and December 31st 2010. Side effects were reported as minor (without subsequent change in systemic medication), moderate (associated with a change in systemic dosage or class of immunosuppressive therapy or in the presence of Cushingoid face or weight gain) or severe (hospitalization or life threatening).¦Results¦52% of boys and 48% of girls are present in the cohort with a mean age at the first visit of 8.1 years (1.7-15.6). Intermediate uveitis consisted of the commonest aetiology with 8 patients (35%), juvenile idiopathic arthritis (JIA) in 7 (30%), Behçet's disease in 3 (13%) and others in 5 (22%). The overall length of therapy was longer for prednisone (26.6 ± 5.4 patient / year), but was similar between methotrexate (22.1 ± 5.4 patient / year) and azathioprine (15.2 patient / year). Moderate side effects were respectively 64% for corticosteroids therapy, 54% with methotrexate and 14% with azathioprine. One severe and one moderate side effect were observed with anti-TNFα respectively stage III anaphylactic shock and pain during injection associated with a redness of the site of injection and limping after the injection.¦Discussion¦Immunomodulating agents allow a rapid decrease in corticosteroid therapy, but one severe side effect was observed with anti-TNFa agents. These agents are considered in most countries as third line therapeutic agents.

Urological complications in renal transplantation from cadaveric donor grafts: a retrospective analysis of 20 years.

INTRODUCTION: This study is a retrospective analysis of ureteral complications and their management from a monocenter series of 277 consecutive renal transplantations. MATERIALS AND METHODS: From September 1979 to June 1999, 277 renal transplantations (cadaveric origin) were performed in 241 patients. The ureter from the kidney graft was inserted into the bladder according to the technique of extravesical implantation described by Lich-Gregoir and Campos-Freire. The study analyzed the time of occurrence and the type of complications observed. The different procedures to restore the transplanted urinary tract are presented. RESULTS: Complications occurred in 43/277 renal transplantations (15.5%). Anastomotic urine leakage or ureteral stricture were the most frequent. The time to appearance of these complications was either short (<1 month) or late (>1 month) in a similar number of cases. Most cases were managed surgically: 33/43 cases (76.7%). The most frequent surgical repair was ureterovesical reimplantation (n=13), followed by: ureteroureteral end-to-end anastomosis (native ureter-ureter transplant, n=5); pyeloureteral anastomosis (native ureter-renal pelvis transplant, n=5); simple revision of ureterovesical implantation (n=4); resection and end-to-end anastomosis of the transplant ureter (n=2); calico-vesicostomy (graft-bladder, n=1); implantation according to Boari (n=1); pyelovesicostomy with bipartition of bladder (n=1), and pyeloileocystoplasty with detubularized ileal graft (n=1). No deaths related to any of the urological complications were reported. However, 2 consecutive vesico-renal refluxes led to the loss of the kidney graft in the long-term. CONCLUSION: The rate of complications observed in this retrospective analysis is similar to the experience of other studies, ranging from 2 to 20%. If the classical extravesical ureteral bladder implantation is to remain an attractive technique due to its simplicity, the surgical team at the training center should be aware of all the means to prevent any ureteral complications, such as the choice of another implantation technique and/or insertion of a transient ureteral stent.

Infection after total ankle replacement : A 5-year retrospective analysis of 92 implanted ankle prostheses (2004-2008).

Objectives: Total ankle replacement (TAR) is increasingly used for treatment of primary or posttraumatic arthritis of the ankle joint, if joint movement is intended to be preserved. Data on characteristics and treatment of ankle prosthetic joint infection (PJI) is limited and no validated therapeutic algorithm exist. Therefore, we analyzed all infections, which occurred in a cohort of implanted ankle prostheses during a 5-year-period.Methods: Between 06/2004 and 12/2008, all patients with an implanted ankle prosthesis at our institution were retrospectively reviewed. All patients were operated by the same surgical team. Ankle PJI was defined as visible purulence, acute inflammation on histopathology, sinus tract, or microbial growth in periprosthetic tissue or sonication fluid of the removed prosthesis. The surgery on the infected ankle prosthesis and the follow-up were performed by the surgical team, who implanted the prosthesis. A specialized septic team consisting of an orthopaedic surgeon and infectious diseases consultant were included in the treatment.Results: During the study period, 92 total ankle prostheses were implanted in 90 patients (mean age 61 years, range 28-80 years). 78 patients had posttraumatic arthritis, 11 rheumatoid arthritis and 3 other degenerative disorder. Ankle PJI occurred in 3 of 92 TAR (3.3%), occurring 1, 2 and 24 months after implantation; the causative organisms were Enterobacter cloacae, Streptococcus pyogenes and Staphylococcus epidermidis, respectively. The ankle prosthesis was removed in all infected patients, including debridement of the surrounding tissue was debrided and insertion of an antibiotic loaded spacer. Provisional arthrodesis was performed by external fixation in two patients and by plaster cast in one. A definitive ankle arthrodesis with a retrograde nail was performed 6 to 8 weeks after prosthesis removal. One patient needed a flap coverage. All 3 patients received intravenous antibiotic treatment for 2 weeks, followed by oral antibiotics for 4-6 weeks. At follow-up visit up to 18 months after start of treatment, all patients were without clinical or laboratory signs of infection.Conclusions: The infection incidence after TAR was 3.3%, which is slightly higher than reported after hip (<1%) or knee arthroplasty (<2%). A two-step approach consisting of removal of the infected prosthesis, combined with local and systemic antibiotic treatment, followed by definitive ankle arthrodesis shows good results. Larger patient cohort and longer follow-up evaluation is needed to define the optimal treatment approach for ankle PJI.

Synovial sarcomas usually metastasize after >5 years: a multicenter retrospective analysis with minimum follow-up of 10 years for survivors.

Background: Synovial sarcoma (SS) is a malignant soft tissue sarcoma with a poor prognosis because of late local recurrence and distant metastases. To our knowledge, no studies have minimum follow-up of 10 years that evaluate long-term outcomes for survivors. Patients and methods: Data on 62 patients who had been treated for SS from 1968 to 1999 were studied retrospectively in a multicenter study. Mean follow-up of living patients was 17.2 years and of dead patients 7.7 years. Results: Mean age at diagnosis was 35.4 years (range 6-82 years). Overall survival was 38.7%. The 5-year survival was 74.2%; 10-year survival was 61.2%; and 15-year survival was 46.5%. Fifteen patients (24%) died of disease after 10 years of follow-up. Local recurrence occurred after a mean of 3.6 years (range 0.5-14.9 years) and metastases at a mean of 5.7 years (range 0.5-16.3 years). Only four patients were treated technically correctly with a planned biopsy followed by a wide resection or amputation. Factors associated with significantly worse prognosis included larger tumor size, metastases at the time of diagnosis, high-grade histology, trunk-related disease, and lack of wide resection as primary surgical treatment. Conclusions: In SS, metastases develop late with high mortality. Patients with SS should be followed for >10 years.

Sorafenib as third- or fourth-line treatment of advanced gastrointestinal stromal tumour and pretreatment including both imatinib and sunitinib, and nilotinib: A retrospective analysis.

BACKGROUND: Tyrosine kinase inhibitors (TKI) improve the outcome of patients with advanced gastrointestinal stromal tumour (GIST), but treatment failure is frequent, and prognosis then bleak. Smaller trials in this setting suggested activity for sorafenib, a multikinase inhibitor of receptor tyrosine kinases and RAF serine/threonine kinases. PATIENTS AND METHODS: We retrospectively evaluated the efficacy of sorafenib, starting dose 400mg twice daily, in a large community-based cohort of 124 patients treated in 12 European and one United States (U.S.) cancer centre. All but one patient had a WHO performance score 0-2. All had failed both imatinib and sunitinib, 68 patients nilotinib and 26 had failed investigational therapy, too. RESULTS: Twelve (10%) patients responded to sorafenib and 70 (57%) patients achieved disease stabilisation. Sorafenib was moderately tolerated, and toxicity reported in 56% of the patients. Rash, hand-foot-syndrome and diarrhea occurred frequently. Sorafenib dosage was reduced in a third of patients, but this did not have an impact on progression-free survival (PFS) (p=0.15). Median PFS was 6.4months (95% confidence interval [CI], 4.6-8.0months) and median overall survival (OS) 13.5months (95% CI, 10.0-21.0months). Patients with a good performance status and those who responded to sorafenib had a significant better PFS. CONCLUSION: We conclude that sorafenib is active in GIST resistant to imatinib, sunitinib and nilotinib. These results warrant further investigation of sorafenib or similar molecules in GIST.
