RESUMEN
PURPOSE: Early breast cancer follow-up guidelines for patients who underwent surgery suggest a regular and accurate clinical examination of the breast area, for an early identification of cutaneous or subcutaneous breast cancer relapse. Nonetheless, breast skin lesions arising in patients treated with mastectomy for breast cancer can be caused by several diseases. A series of diagnostic hypotheses should be considered, not only focusing on cutaneous metastasis, but also on dermatologic and systemic diseases. CASE REPORT: In February 2015, a 37-year-old patient underwent a right subcutaneous mastectomy for stage IIA breast cancer. Five months after beginning adjuvant chemotherapy, she noted hyperpigmentation and thickening of the skin on the right breast. Differential diagnosis included local relapse, skin infection, lymphoma, or primary cutaneous disease, and a skin biopsy was performed. The histopathologic specimen showed full-thickness sclerosis, with features of localized morphea. Therapy with clobetasol was prescribed, with progressive resolution of the thickness. The collaboration between many professionals in a multidisciplinary team (oncologist, dermatologist, plastic surgeon, and pathologist) was crucial to achieving the diagnosis. CONCLUSION: In the literature, some articles describe correlation between connective tissue diseases and silicone breast implants, but the pathogenetic mechanisms are unknown. We report a rare case of breast morphea after positioning a silicone implant in a patient who had undergone mastectomy. This clinical report represents an interesting model of multidisciplinary management of a patient with breast cancer who developed an uncommon dermatologic disease. Further studies are needed to clarify the association between silicone implants and breast morphea.

BACKGROUND: Many efforts have been made to predict prognosis of newly diagnosed Hodgkin Lymphoma (HL) patients. Objective of this study was to investigate the association between early reduction of Thymus and Activation-Regulated Chemokine after the first ABVD cycle (TARC-1) and prognosis of HL patients. METHODS: Serum samples of 116 HL patients were collected at baseline, after every ABVD cycle and during follow-up. The 99th centile of TARC distribution in a group of 156 independent healthy subjects (800pg/ml) was considered as cut-off for discriminating between abnormal and normal TARC values. FINDINGS: 101 patients out of 116 had baseline TARC above 800pg/ml (median value 27515pg/ml (IQR, 11001-68139)) and were the object of this analysis. TARC-1 significantly decreased to a median value of 556pg/ml (IQR, 378-977pg/ml). TARC-1 values below 800pg/ml were associated with success of therapy (p=0.0003) and PET-2 negativity (p=0.001). TARC-1≤800pg/ml identified a population with a significantly higher 5-years PFS in the whole cohort (90.1% vs 55.6%; p<0.0001) and in both subgroups of advanced (p=0.003) and early stage patients (p=0.021). At multivariable analysis, TARC-1 was significant independent predictor of PFS (p=0.0035). INTERPRETATION: Early reduction of TARC serum levels can predict success of treatment, being associated with achievement of interim PET-2 negative and favorable long-term outcome in HL patients receiving ABVD as front-line therapy.

Case 1. A 54 year old woman affected by chronic asthmatic bronchitis from the age of 11 years and ulcerous recto-colitis from 15 years, presented several erythematous-violaceous macules from the trunk including abdominal region to all skin surface except the face. Case 2. A 17 year old woman presented a similar hyperpigmentation in the same areas. In both patients histology showed a thin epidermis with vacuolar changes of basal layer and apoptotic bodies and melanophages rich in melanosomes in the papillary dermis. Our diagnosis was Ashy dermatitis. Clinico-pathological correlations and treatment options are discussed.

The efficaciousness of ACE inhibitors in arterial blood hypertension is well known. These drugs decreased the incidence of hypertension and myocardial infarction in population. However, they increase tissue levels of some kinines, that may be responsible of some adverse reactions (cough, etc.). Angiotensin-receptor antagonists can minimize the adverse reactions due to kinine accumulation and may increase the safety of the antihypertensive drug-treatment. Pharmacological and clinical aspects of angiotensin-receptor antagonists are discussed.

Antibiotics of the beta-lactam class may cause coagulation defects and bleeding. It has been suggested that N-methyltetrazolethiol (NMTT), a common side chain group at the 3'-position of the cephem or 1-oxacephem frame, could be responsible for the hypoprothrombinemic effect of the antibiotics and that it could inhibit the liver vitamin K-epoxide reductase activity. Flomoxef (6315-S) is a new oxacephem antibiotic which differs from latamoxef because it has [1-(2-hydroxethyl)-1H-tetrazol-5-yl] thiomethyl (HTT) as a side chain at the 3'-position of cephem group instead of NMTT and an extensive modification of 7 beta-acylamino side chain. The present study was carried out to study its effects on vitamin K-dependent blood coagulation parameters in human volunteers. Ten adult patients (6 men and 4 women), suffering from chronic bronchitis, entered into the study. Each patient received ten 1 g i.m. injections of flomoxef at 12-hourly intervals. Apparently, the treatment with this oxacephem antibiotic had no significant effect. PT, PTT and fibrinogen remained in the normal range in all patients and factors II+VII+X, protein C, protein S and AT III were not depleted. The trend was similar both in men and women. Based on the results of the present study, we conclude that flomoxef is an antibiotic that does not exhibit an effect on blood coagulation, even in males.(ABSTRACT TRUNCATED AT 250 WORDS)

The safety and tolerability of carvedilol, a new antihypertensive agent with the combined pharmacological activities of beta-blockade and vasodilation, and of nifedipine were investigated in patients with essential hypertension and non-insulin-dependent (type II) diabetes mellitus. Twenty patients were openly randomized to receive 25 mg carvedilol once daily (five men and five women; mean age, 63 years) or 10 mg nifedipine t.i.d. (three men and seven women; mean age, 64 years) for a period of 4 weeks. Baseline mean sitting blood pressures were 168/98 and 169/95 mm Hg in the carvedilol and nifedipine groups, respectively. Baseline mean areas under the curve (AUC) of the intravenous glucose tolerance test (IVGTT) for the carvedilol and nifedipine groups were 6,136 +/- 1,195 and 6,287 +/- 1,228 mg/dl/min, respectively. Demographic and efficacy variables were not statistically different between treatment groups. After 4 weeks of therapy, mean sitting blood pressure was significantly (p less than 0.02) reduced to 144/91 mm Hg in the carvedilol group and to 149/87 mm Hg in the nifedipine group. Week 4 IVGTT AUC values of 5,735 +/- 1,464 mg/dl/min in the carvedilol group and 5,988 +/- 993 mg/dl/min in the nifedipine group, representing mean reductions of 6.14% and 3.17%, respectively, were not statistically different from baseline. Both treatments were well tolerated. No patient experienced adverse events in the carvedilol treatment group, whereas two patients in the nifedipine group reported episodes of headache (one patient) and palpitations (one patient); each episode was mild in severity and considered to be related to study medication.(ABSTRACT TRUNCATED AT 250 WORDS)

Side effects have been observed when 14-membered macrolides, erythromycin and troleandromycin, have been prescribed concurrently in patients receiving therapeutic doses of theophylline. Rokitamycin is a new 16-membered macrolide antibiotic. We have evaluated its effect on theophylline serum concentrations in 12 adult patients suffering from chronic obstructive pulmonary disease. Initially, six patients were treated for four consecutive days with theophylline as sustained-release formulation in the amount of 600 mg daily; six other patients received for four consecutive days a short term intravenous infusion of 240 mg aminophylline, given over a period of 30 min twice daily. On the last day, blood samples were taken for theophylline determination. Theophylline concentrations were measured serially for 12 hours after oral formulation and 4 hours after aminophylline by enzyme immunoassay technique. Subsequently, while theophylline and aminophylline treatments were continued at the same dosage, each patient received in addition rokitamycin tablets, 400 mg every 12 hours. After seven days of this combined medication, the serial assays of serum theophylline were repeated at the same time intervals as before. Concomitant administration of therapeutic doses of rokitamycin did not affect significantly the steady-state pharmacokinetics of oral theophylline and did not alter the (pseudo-) steady-state pharmacokinetics of intravenous aminophylline, showing that the two drugs may be coadministered without any theophylline dose adjustment.

The authors investigated the possible correlation between blood concentrations and clinical outcome in 38 auranofin-treated patients with rheumatoid arthritis, diagnosed according to ARA criteria. The results showed that the whole blood gold concentrations did not correlate with the clinical parameters investigated and some laboratory findings. The authors discuss this lack of correlation, suggesting that a clear genetic disposition can interfere with the clinical response, affecting the metabolism and kinetics of the drug.

The Swiss mouse is considered a satisfactory model for experimental chronic chagasic myocarditis and there is some evidence of an immunopathologic mechanism in the development of this disease. To further support this conjecture, 45-day-old albino Swiss mice (40 animals) were immunized with homologous heart in complete Freund's adjuvant. As controls, 20 animals were likewise inoculated with allogeneic testis, as "non-related" antigen. Three mice from the former group died suddenly at 19-21 days postinoculation while the survivors were sacrificed at 60 days for serum samples, and histologic analysis of the heart and skeletal muscle. Electrocardiographic records were taken at Days 0, 30, and 60 postinoculation. Of myocardium-inoculated animals and testis-inoculated mice 33/37 (89%) and 1/20 (5%), respectively, exhibited myocarditis (P less than 0.001). Histologic lesions were highly reminiscent of those observed in chronic experimental Chagas' disease of Swiss mice. Antimuscle antibodies were seen, by indirect immunofluorescence employing cryostat sections, in 30/33 (91%) of the former group and in 3/20 (15%) of the latter (P less than 0.001), some of which recognized a surface antigen of primary cultured fetal rat myocardiocytes. Mice inoculated with myocardium also exhibited electrocardiographic abnormalities consisting in QRS interval widening. Results show that following an autoimmune experimental design the main features of chronic chagasic myocarditis may be reproduced in the Swiss mouse. This agrees with the likely role of an immunopathologic mechanism in heart damage due to Trypanosoma cruzi infection.
