[Eyelid melanoma: our experience a propos of 23 cases]. / Le mélanome palpébral : notre expérience à propos de 23 cas.

INTRODUCTION: Eyelid melanoma is a rare condition corresponding to less than 1% of all eyelid malignancy. The aim of the current study is to present the experience of our department. PATIENTS AND METHODS: From 1986 to 2009, 972 patients with a melanoma have been studied retrospectively. Each patient was evaluated in relation with age, sex, location of the tumor, histology (Breslow and Clark included), surgical treatment, recurrence, and finally with follow up. RESULTS: Twenty-three patients with eyelid melanoma and a strong female incidence (69.5%) were identified. Median age was 68.3 years. In most cases (71.4%), tumor was located on the right inferior eyelid in continuity with the malar region. LMM had the higher incidence (60.8%), followed by the nodular melanoma (21, 7%) and the SSM. The median Breslow was 0.77 while the median Clark 1.68. Surgery was the treatment of choice including direct closure, the use of full thickness skin graft and local or regional flaps. Three patients had local recurrence associated to nodular metastases in one of them. CONCLUSION: Surgical treatment of eyelid melanoma is a challenge for every reconstructive surgeon. Early detection remains the "gold standard" for every reconstructive option respecting the esthetic and function of this precious anatomic location.

Kaposi's sarcoma after repeated surgical procedures in an immunocompetent patient: the lymphatic hypothesis.

A 63-year-old Swiss patient developed acquired nodules on his right palm after 3 localized surgeries, called 'needle fasciotomy', for Dupuytren's disease. Kaposi's sarcoma (KS) was diagnosed in a biopsy of a nodule. A positive immunolabeling and serology for human herpesvirus 8 has been found, but human immunodeficiency virus and hepatitis C identification remained negative. The nodules were limited to the surgically traumatized area. This first report of a nonimmunocompromised patient developing a KS after repeated surgeries in a unique peculiar localized area with a dense lymphatic network sustains the hypothesis that tissue alterations involving the lymphatic system could play a central role in the occurrence of KS.

Sequential treatment with biologics: switching from efalizumab to etanercept in 35 patients with high-need psoriasis.

BACKGROUND: Use of biological agents has been shown to be an efficacious approach in psoriasis, when traditional treatments fail. However, there are limited data on the effectiveness and safety of switching from one biological agent to another. OBJECTIVES: We aimed to evaluate the effectiveness and safety of etanercept as a sequential treatment in patients previously treated with efalizumab, and to evaluate different transition strategies from efalizumab to etanercept. METHODS: We present a retrospective study in patients with high-need plaque psoriasis who were unable to continue efalizumab and were immediately switched to etanercept. RESULTS: We included 35 patients during a 4.5-year period. At 24 weeks of etanercept therapy, 57% of patients had a PASI reduction of 75%, suggesting that alternating between biological agents is feasible. We used three different switching approaches: (i) etanercept in combination with cyclosporine as bridge therapy, (ii) etanercept in combination with methotrexate as bridge therapy, (iii) etanercept monotherapy. Combination therapy was efficacious in all patients, including eight patients with rebound phenomenon with efalizumab. Etanercept was discontinued in two patients as a result of serious adverse events that consisted of an oral squamous cell carcinoma and a diffuse B-cell-non-Hodgkin lymphoma. CONCLUSIONS: In our experience, it seems that etanercept alone may not be sufficient when transitioning from efalizumab in high-need patients with severe worsening or rebound of psoriasis. In such patients, combination of etanercept with cyclosporine or methotrexate is a more effective approach. Non-response to efalizumab did not preclude clinical response after switching to etanercept.

sRANKL/osteoprotegerin complex and biochemical markers in a cohort of male and female hemodialysis patients.

OBJECTIVE: The processes involved in bone remodeling are under the control of a multitude of systemic and local factors. Receptor activator of nuclear factor-kappaB ligand (RANKL)/osteoprotegerin (OPG) complex seems to be one of the major modulators of bone remodeling. In chronic renal failure, the cytokine systems involved in the regulation of bone turnover may be influenced, and are therefore likely to contribute to the pathogenesis of renal bone disease. The aim of the present study was the evaluation of RANKL/OPG complex in concert with other biochemical parameters in hemodialysis (HD) patients and the investigation of possible correlations between the serum levels of its components and several clinical parameters of these patients. METHODS: We measured serum levels of intact PTH (iPTH), total serum RANKL (sRANKL), osteoprotegerin (OPG), alkaline phosphatase, osteocalcin (OC), and tartrate-resistant acid phosphatase (TRAP) in 104 HD patients and in 40 healthy controls. RESULTS: The average serum OPG level was significantly higher, whereas the average serum concentration of RANKL was nonsignificantly lower in patients on HD therapy than in age-matched healthy controls. Consequently, the mean sRANKL/OPG ratio was significantly lower in patients. Among HD patients, serum level of OPG increased significantly with aging and with a longer duration of hemodialysis. RANKL levels were inversely correlated with age nonsignificantly in the whole group of patients and significantly in the female subgroup (r=-0.322, p=0.035), whereas RANKL/OPG ratio declined significantly with age in the entire cohort of patients (r=-0.259, p=0.008). In addition, iPTH, OC, TRAP were significantly higher in female, whereas RANKL/OPG ratio was significantly higher in male than female patients. CONCLUSIONS: Lower values of sRANKL/OPG ratio in HD patients, as well as the age and duration of HD dependent increase of serum OPG and the age-dependent decrease of sRANKL concentration especially in women cannot be explained by the elimination of renal clearance only. Alterations in sRANKL/OPG ratio might reflect a compensatory mechanism to modulate bone remodeling in these patients.

Polychondritis associated with Schönlein-Henoch purpura: report of a case.

A case of polychondritis in a psoriatic boy is reported, involving purpura, arthritis which included the costochondral joints, and swelling of his scrotum, eyelids and pinnae. Many of his clinical manifestations showed an overlapping presentation with Schönlein-Henoch purpura (SHP).

Clinical features, complications and treatment outcome of childhood brucellosis in central Greece.

OBJECTIVES: To examine the epidemiology, clinical and hematological characteristics, complications and treatment outcome of childhood brucellosis in central Greece. METHODS: Retrospective record review of all patients 0-14 years of age with brucellosis admitted during a 16-year period between 1984 and 1999. RESULTS: A total of 39 cases (23 males, median age 132 months) were recorded in which the diagnosis was confirmed by a positive culture (n=30) or detection of IgM antibodies with ELISA (n=9). About 38% of these patients came from families of farmers or shepherds who owned a few domestic animals or small herds of goats or sheep and another 43% had consumed dairy products bought from shepherds. In 41% of the cases another family member developed symptomatic infection. Most of the patients presented with fever (61%) and musculoskeletal symptoms (69%). Splenomegaly was recorded in 38% and hepatomegaly in 28% of the cases. Anemia (39%) and monocytosis (31%) were the most common hematological manifestations, followed by lymphopenia (18%). Unusual complications were detected in two patients who developed thrombocytopenic purpura and acute facial nerve palsy, respectively, but recovered without long-term sequelae. None of the 22 patients who received a combination of two or three antibiotics for > or =6 weeks and had adequate follow-up had a relapse. CONCLUSION: Childhood brucellosis remains an important public health problem in central Greece. It usually occurs in families that raise small ruminants and the development of symptomatic infection in more than one family member is common. It may cause serious complications in children and treatment with at least two antibiotics for not less than six weeks appears to be effective.

Gastric autoimmunity in children and adolescents with type 1 diabetes: a prospective study.

BACKGROUND/AIMS: Type 1 diabetes (T1DM) is associated with gastric autoimmunity, which is characterized by the presence of parietal cell antibodies (APCA). We investigated gastric autoimmunity prevalence in T1DM children, its manifestations, determinants and association with thyroid gland (anti-Tg, anti-TPO) and pancreatic ß-cell autoimmunity (anti-GAD) at baseline and 4 years later. METHODS: The initial cohort (D1) included 97 children with T1DM. At follow-up after 4 years (D2), 84.5% of participants were evaluated. We assessed APCA, anti-Tg, anti-TPO, and anti-GAD presence, as well as symptoms of gastritis. APCA-positive patients were evaluated with gastrin, B12, ferritin levels and were submitted to gastroscopy. RESULTS: Thyroid antibody positivity was increased among the APCA-positive patients. Four years later, among initially APCA-positive patients, 2/6 became APCA negative, while 4/6 developed high titers of APCA. On gastroscopy, 2 patients had chronic hypertrophic gastritis and one Helicobacter pylori gastritis. CONCLUSIONS: Gastric autoimmunity was associated with thyroid autoimmunity and anti-GAD persistence. After 4 years, the majority of APCA-positive patients developed high titers of APCA and mild symptoms of gastritis. Thus, patients with T1DM, and in particular those with thyroid and/or pancreatic autoimmunity, should have periodic autoantibody screening for the early diagnosis and follow-up of gastric autoimmunity.

Atopic patients with genital warts have a more protracted clinical course and a greater probability of recurrences.

The factors predicting an unfavourable response of genital warts to treatment have not been determined. The disease characteristics were recorded for 390 patients with genital warts and treated by cryotherapy. The time to achieve clearance was recorded. A personal and family history of asthma, hay fever or eczema, as well as a personal history of common warts and number of recurrences was obtained by telephone four to five years after the clinical visits. In multiple regression analysis, the number of lesions (P < 0.001), extent of the disease (P = 0.003) and personal history of atopy (P = 0.001) were found to influence the time until response to treatment. Similar results were obtained for family history of atopy. The number of sexual partners (P = 0.007), extent of the disease (P = 0.009) and personal history of atopy (P < 0.001) were the main factors influencing the probability of recurrence in multiple logistic regression. The results for family history of atopy were again similar. The study concludes that atopy is a major factor influencing the time frame of the therapeutic response and the probability of recurrence in patients with genital warts.

Coeliac disease and alopecia areata in childhood.

Coeliac disease is a genetic, immunologically mediated small bowel enteropathy that causes malabsorption. The immune inflammatory response to gluten frequently causes damage to many other tissues of the body. We report the association of coeliac disease and alopecia areata in two children, a 13-year-old girl and a 29-month-old girl. Both of our patients had immunoglobulin A (IgA) class endomysial antibodies, IgA and immunoglobulin G (IgG) antigliadin antibodies and subtotal villous atrophy on jejunal biopsy. Administration of a gluten-free diet to our patients resulted in complete hair growth and improved the gastrointestinal symptoms.
