Abstract
BACKGROUND The addition of calcipotriol ointment to PUVA therapy for psoriasis vulgaris results in a lower total UVA dose and a faster onset of response. The addition of calcipotriol cream to PUVA, however, has not been studied. OBJECTIVE To investigate whether combining calcipotriol cream with PUVA therapy has a UVA sparing effect. METHODS We performed a randomized, multicentre, vehicle-controlled, double-blind, 12-week comparative study including 120 patients with psoriasis covering 20-50% body surface area. The study consisted of a washout phase followed by a 10-week treatment phase. PUVA therapy three times weekly was added within 1 week after randomization. Efficacy was assessed by the Psoriasis Area and Severity Index (PASI). RESULTS At baseline the mean PASI scores were 17.5 and 19.2 in the calcipotriol and vehicle (placebo) groups, respectively. At the end of treatment, the mean PASI scores were 2.65 and 7.03 (p<0.01), respectively. A reduction in PASI score >90% was observed in 69% of the patients in the calcipotriol-treated group and in 36.4% of the patients in the vehicle group (p<0.01). CONCLUSION Calcipotriol cream plus PUVA clearly reduces the cumulative dose of UVA and improves the response of psoriasis vulgaris to PUVA.

Abstract
BACKGROUND AND STUDY AIMS An ideal treatment for choledocholithiasis in the laparoscopic era has not been established. The objective of this study was to elucidate whether a treatment strategy of performing intraoperative endoscopic retrograde cholangiopancreatography (ERCP) during laparascopic cholecystectomy (when choledocholithiasis is confirmed by intraoperative cholangiography) is better for patients with suspected common bile duct stones than the current strategy (preoperative ERCP followed by laparoscopic cholecystectomy). PATIENTS AND METHODS This was a prospective randomized study to evaluate which of these two approaches was most benefit- and cost-effective for patients with intermediate risk of choledocholithiasis. Patients underwent either preoperative ERCP followed by a laparoscopic cholecystectomy a few weeks later (the "preoperative ERCP" group) or intraoperative ERCP (the "intraoperative ERCP" group). Intraoperative ERCP was performed using the rendezvous technique. RESULTS There were 64 patients in the preoperative ERCP group and 59 patients in the intraoperative ERCP group. The demographic and clinical characteristics of the two groups were similar, except that the bilirubin and gamma-glutamyl transferase (GGT) levels and the number of patients treated on an inpatient basis were higher in the preoperative ERCP group. Success rates were similar (96.6 % in the preoperative ERCP group vs. 90.2 % in the intraoperative ERCP group in the per-protocol study). Total morbidity, post-ERCP morbidity, and post-ERCP acute pancreatitis rates were higher in the preoperative ERCP group, but there were no differences between the two groups in the frequency of residual common bile duct stones, the conversion rate to open cholecystectomy, or surgical morbidity. The length of hospital stay and costs were lower in the intraoperative ERCP group despite the longer surgical times in this group. Univariate analysis did not find any relationship between morbidity and total bilirubin or GGT. Logistic regression analysis confirmed that morbidity was related only to the treatment group and the time spent in the operating room: the relative risk (RR) was 4.37 for morbidity and 1.015 for the time spent in the operating room); the RR for papillotomy was 5.49. CONCLUSIONS Both treatment approaches were equally effective but the intraoperative ERCP group had less morbidity, a shorter hospital stay, and reduced costs. The lower morbidity in the intraoperative ERCP group resulted from the lower rate of papillotomy and lower rates of post-ERCP pancreatitis and cholecystitis. Total morbidity was principally related to the type of treatment approach used.

Abstract
BACKGROUND The treatment of keloids and hypertrophic scars has been difficult and a recent French study showed that bleomycin has been useful in the treatment of these lesions. OBJECTIVE To determine the effectiveness and safety of bleomycin in the treatment of hypertrophic scars and keloids when this drug is administered through multiple superficial punctures. METHODS We applied bleomycin to keloids and hypertrophic scars in 13 patients using a multiple-puncture method on the surface of the skin. All patients were given bleomycin at a concentration of 1.5 IU/ml. Clinical response after treatment was classified according to the following scale: complete flattening (100%), highly significant flattening (>90%), or significant flattening (75-90%). RESULTS The clinical response was very positive in all cases: complete flattening in six cases, highly significant flattening in six cases, and significant flattening in one case. Two patients presented a recurrence as a small nodule 10 and 12 months after the last infiltration. CONCLUSIONS These clinical findings show that administration of bleomycin in keloids and hypertrophic scars shows promise and needs further investigation.

Abstract
CD24 or Nectadrin is a cell surface glycoprotein expressed in pre-B lymphocytes, T lymphocytes, neurons, muscle cells and carcinoma cells. Its function is not completely known, but it has been suggested that it is involved in cell adhesion and signalling. CD24 has recently been identified as the human molecule homologous to the murine heat-stable antigen (HSA). HSA is expressed by murine keratinocytes and delivers costimulatory signals in T-cell activation. Long-term cultures of normal human keratinocytes (HKC) were obtained from skin of human female breast sections and either left untreated or were treated with phorbol-12-myristate-13-acetate (PMA) at 10-100 ng/ml, calcium 0.5-2 mM or IFN-gamma 100-1000 U/ml, for 24-48 h. Using RT-PCR and flow cytometry we showed that HKC express low levels of CD24 even under basal conditions, and the treatment with calcium, PMA or IFN-gamma increased levels of CD24 mRNA and protein. To the best of our knowledge, this is the first report to measure CD24 expression and production by cultured HKC in basal conditions and after stimulation. Further studies are needed to determine biological and therapeutical relevance of these findings.

Abstract
There are several syndromes in which neurological and cutaneous alterations of vascular origin, among other symptoms, occur. The key point of this fact is that these cutaneous signs permit early diagnosis, thus helping in further recognition of more complex syndromes and preventing unnecessary, harmful and costly diagnostic procedures or having to wait until the appearance of neurological signs. Therefore, these diseases should be classified attending to the most notorious vascular lesions they show, though they may show other less frequent cutaneous vascular lesions. In this way, these syndromes can be classified as associated with nevus flammeus (Sturge-Weber, Shapiro-Shulman, Bonnet-Dechaume-Blanc, Cobb, Klippel-Trenaunay, Fegeler, Robert), cavernous hemangiomas (Maffucci, blue-rubber-bleb-nevus, Proteus, Bannayan-Zonana, Riley-Smith, familial cavernous angiomatosis, POEMS syndrome), capillary hemangiomas (Rubinstein-Tayabi, Coffin-Siris, PHACE syndrome), telangiectasia (congenital telangiectatic cutis marmorata, Rendu-Osler-Weber, ataxia telangiectasia, Cockayne, De Sanctis-Cacchione), livedo reticularis (Sneddon, Divry-van-Bogaert), angioqueratoma (Fabry disease, Fucosidosis) and hemangioblastoma (Von Hippel-Lindau). Though we have tried that these vascular lesions should be named as angiomas if they are malformations and hemangiomas if they are benign neoplasias, they are called following morphological aspects rather than other criteria, due to their unknown origin.

Abstract
Pentoxifylline (PTX) is a methylxanthine derivative used in a wide range of dermatoses. As well as its hemorrheologic activity, PTX has anti-inflammatory properties. Buflomedil chlorhydrate (BC) is another hemorrheological drug with peripheral vasodilatory action, whose clinical uses are similar to those of PTX. Both drugs increase intracellular levels of cAMP, either secondary to phosphodiesterase inhibition (PTX) or adenyl-cyclase stimulation (BC). Long-term cultures of normal human keratinocytes were prepared in a free-serum medium, and stimulated with 1 mg/ml of phorbol 12-myristate 13-acetate (TPA) and PTX or BC (100-1000 micrograms/ml). Levels of TNF-alpha, IL-1 alpha, IL-1 beta, IL-8 and TGF-beta 1 using ELISA and Northern blot or RT-PCR techniques were measured. TPA-induced TNF-alpha and IL-8 release from keratinocytes. TPA did not induce IL-1 alpha or IL-1 beta release of keratinocytes. TPA increased RNA expression of the TNF-alpha, IL-1 alpha, IL-1 beta, IL-8 and TGF-beta 1. BC diminished TPA-induced TNF-alpha and IL-8 release from keratinocytes; in the case of IL-8 it is possible that this inhibition occur to transcriptional level. Moreover PTX was unable to inhibit TNF-alpha and IL-8 synthesis and expression. PTX and BC reduced TPA-induced IL-1 alpha and beta expression. It is possible that BC action is specifically exerted on keratinocytes, because we did not find similar results with TNF-alpha and IL-8 synthesis in mononuclear peripheral blood cells.

Abstract
Extracts from the rhyzome of Curcuma longa are widely used as food additives in India and other Asiatic and Central American countries. It has been shown that these extracts ("turmeric"), as well as "curcumin" and related phenolic compounds isolated from Curcuma, have a powerful antioxidant action when tested in in vitro systems. Moreover, previous research from our laboratories has shown significant decreases in the levels of lipid peroxides in the blood of both mice and human subjects administered "turmeric." Our present research complements the previous data, showing that a daily intake of turmeric equivalent to 20 mg of the phenolic antioxidant curcumin for 60 days decreases the high levels of peroxidation of both the HDL and the LDL, in vivo, in 30 healthy volunteers ranging in age from 40 to 90 years. The effect was quite striking in the persons with high baseline values of peroxidized compounds in these lipoproteins, while no apparent change took place in the persons having low baseline values. In view of current concepts on the atherogenic role played by peroxidized HDL, and especially by peroxidized LDL, as inducers of foam and smooth cell proliferation in the arterial wall, this preliminary experiment suggests that the Curcuma phenolic antioxidants, because of their high antioxidant activity and lack of toxicity, might be a useful complement to standard hypo-lipidemic drugs in the prevention and treatment of atherosclerosis.

Abstract
The urocanic acid cis isomer (cis-UCA) is a possible cutaneous photoreceptor for the immunomodulatory phenomena that follow ultraviolet B irradiation. Several experiments in animals show an inhibitory action of cis-UCA on cellular immunity. However, the action of cis-UCA on the synthesis of cytokines in keratinocytes remains unknown. Long-term cultures of normal human keratiocytes were prepared in a serum-free medium, and stimulated with 1 microgram/ml of phorbol 12-myristate 13-acetate (TPA) and UCA or UVB-UCA (10-100 micrograms/ml). Synthesis of the following cytokines was measured using ELISA and Northern blot techniques: TNF-alpha, IL-1 alpha, IL-1 beta, IL-6, IL-8 and TGF-beta 1. TPA increased TNF-alpha protein levels in culture supernatants. No changes in Il-1 alpha and IL-1 beta protein levels were detected in basal culture supernatant after TPA stimulus. TPA augmented RNA expression for TNF-alpha, IL-1 alpha, IL-1 beta and TGF-beta 1. UCA isomers did not induce cytokine changes in protein synthesis. Expression of IL-1 alpha and IL-1 beta genes was increased after exposure to 100 micrograms/ml UVB-UCA (70 micrograms/ml cis-UCA). A slight increase in TNF-alpha RNA expression was detected when the dose of UVB-UCA reached 100 micrograms/ml. No effects on cytokine synthesis were found after UCA stimulus. These results suggest that low doses of cis-UCA do not effect cytokine synthesis by keratinocytes.

Abstract
Toxic epidermal necrolysis (TEN) is a life-threatening disease, the pathogenesis of which remains largely unknown. We describe a 23-year-old woman under treatment with clobazam who developed lesions of TEN in light-exposed areas. Patch and photopatch tests with clobazam were negative. The cellular phenotype and cytokines were studied in blister fluid. The cellular infiltrate was composed mainly of T lymphocytes with a predominant cytotoxic phenotype. There was an increase in the level of tumour necrosis factor (TNF)-alpha in blister fluid compared with the control (a patient with bullous pemphigoid).

Abstract
We report two patients initially diagnosed as having steatocystoma multiplex (SM). Other cysts showed characteristics of eruptive vellus hair cyst (EVHC). More than 30 and 14 cysts, respectively, were removed with histological hybrid characteristics of SM and EVHC. This suggests that SM and EVCH are two closely related entities, which represent a naevoid malformation in the area where the sebaceous duct and hair follicle meet.

Abstract
We report a heart transplant recipient who developed graft-versus-host disease (GVHD) following blood transfusion. We consider that heart transplant recipients should be included in the category of immunosuppressed patients who may develop this disease after being treated with blood products. We also consider that, at the present time, irradiation of blood products is the only useful method of avoiding development of GVHD in these patients.

Abstract
BACKGROUND The frequency of skin cancer in organ transplant recipients is high, up to 15%. OBJECTIVE Our purpose was to determine the incidence of skin cancer in patients who underwent immunosuppression after heart transplantation and to determine the factors important in the appearance of skin cancer. METHODS We studied the frequency of skin cancer in 92 of 111 patients after they underwent heart transplantation between January 1984 and December 1993. RESULTS At least one cutaneous neoplasm (squamous cell carcinoma and/or basal cell carcinoma) developed in 14 patients (15.2%). The basal cell carcinoma to squamous cell carcinoma ratio was 1:1.5. The skin cancer appeared an average of 31.5 months after transplantation; the average was 36 months for squamous cell carcinoma and 25.3 months for basal cell carcinoma. Cumulative risk rose from 4.3% at 1 year up to 43.8% at 7 years after transplantation. The overall incidence of both types of skin cancer was 45.3 per 1000 posttransplant person-years, with an incidence of 25.8 for basal cell carcinoma and 29.1 for squamous cell carcinoma. Most skin cancers developed between 2 and 3 years after transplantation. All patients were exposed to a significant amount of ultraviolet radiation and had skin type II or III. We did not find a significant association between skin cancer and haplotype HLA-A3, HLA-A11, HLA-DR, and the number of mismatches for HLA-B. CONCLUSION We found an increased progressive cumulative incidence of skin cancer in heart transplant recipients for two reasons: (1) immunosuppression and increased exposure to ultraviolet radiation in some patients, and (2) the skin type of certain patients. We emphasize the need for photoprotection in this group of patients and regular skin cancer screening examinations.

Abstract
The appearance of metastasis without clinically demonstrable primary tumor is one of melanoma's challenges. The aim of this study was to recognize the specific characteristics of this occurrence. Based on our study of three patients, we have proposed theories to explain this behavior, its clinical approach, and therapeutic management. We conclude by stressing the importance of finding the primary tumor or traces of it.

Abstract
We report a case of necrobiosis lipoidica located on the glans penis of a patient without diabetes mellitus. Both clinical and histologic features favor the diagnosis of necrobiosis lipoidica, even though the location is unusual. Treatment with pentoxifylline was effective. The differential diagnosis is discussed.

Abstract
Malignant atrophic papulosis is a systemic vaso-occlusive disorder characterized by typical skin lesions. We report two new cases with impairment of blood fibrinolytic activity and alterations in platelet function. The first case showed an increase in plasminogen activator inhibitor-1 (PAI-1) activity, and the second case had a decrease in platelet aggregation induced by adenosine diphosphate and adrenaline but normal with collagen. The impairment of blood fibrinolytic activity and platelet aggregation may have pathogenic and therapeutic implications in malignant atrophic papulosis.

Abstract
Lumbosacral congenital cutaneous lesions have been recognized for a long time by neurologists and neurosurgeons as markers of occult spinal defects, but only a few cases have been published and discussed in the dermatologic literature. Based on a case report, we emphasize the importance of early diagnosis of these lesions, the use of new diagnostic techniques, and the correct management.

Abstract
Skin affectation in patients infected by Toxocara spp. is rare even in endemic regions. We present a case of a patient that consulted us for a urticarial process and a personal history of eating rat cattle meat. After several studies, the diagnosis of secondary urticaria due to Toxocara spp. infection was made. Improvement of the symptoms was observed after treatment with thiabendazole.

Abstract
Perianal basal cell carcinoma (BCC) is a rare tumour and only a few case reports can be found in the literature. In this location, it is important to differentiate a BCC from a basaloid cloacogenic carcinoma, as the first is an invasive but localized tumour, while the second has a high capacity for metastasis.

Abstract
We report the case of a 61-year-old male who presented with a febrile illness accompanied by arthralgia and myalgia. Two months later he developed multiple subcutaneous nodules and enlarged parotid glands. Later two erythematous plaques, clinically compatible with erythema nodosum (EN), were observed. Laboratory investigations revealed abnormal levels of angiotensin converting enzyme and chest radiography showed bilateral hilar enlargement. The biopsy of the cutaneous lesions demonstrated multiple non-caseating granulomas in the subcutaneous tissue without any alterations in the epidermis and the dermis. The cultures for Mycobacteria and fungi were both negative. The clinical picture and histopathological findings were compatible with subcutaneous nodular sarcoidosis. The response to steroid treatment was satisfactory.

Abstract
Subacute cutaneous lupus erythematosus (SCLE) is a recently described distinct subset of lupus erythematosus (LE) having characteristic clinical, serological and genetic features. The clinicopathological and serological findings of 5 patients are reported. From a clinical point of view, we describe two types of cutaneous lesions: psoriasiform and annular pattern. ANA were present in 80% of the cases, anti-Ro was present in 60%, and anti-La in 20%; anti-RNP was positive in 1 patient. Circulating immune complexes were detected in 2 patients, and low levels of complement factors (C3, C4) in another 2 patients. The B- cell alloantigens HLA-A2, HLA-Bw4 or HLA-DR3 were present in 60% of the cases. The cutaneous histopathology revealed important changes in the epidermis. Our findings are similar to those described by most other authors. Also, we would like to emphasize the low disease activity and benign course of our patients.
