Nursing workload and adherence to non-pharmacological measures in the prevention of ventilator-associated pneumonia. A pilot study. / Carga de trabajo y cumplimiento por parte de las enfermeras de las medidas no farmacológicas para la prevención de la neumonía asociada a la ventilación mecánica. Estudio piloto.

OBJECTIVE: To analyse whether adherence to non-pharmacological measures in the prevention of ventilator-associated pneumonia (VAP) is associated with nursing workload. METHODS: A prospective observational study performed in a single medical-surgical ICU. Nurses in charge of patients under ventilator support were assessed. VARIABLES: knowledge questionnaire, application of non-pharmacological VAP prevention measures, and workload (Nine Equivalents of Nursing Manpower Use Score). Phases: 1) the nurses carried out a educational programme, consisting of 60-minute lectures on non-pharmacological measures for VAP prevention, and at the end completed a questionnaire knowledge; 2) observation period; 3) knowledge questionnaire. RESULTS: Among 67 ICU-staff nurses, 54 completed the educational programme and were observed. A total of 160 observations of 49 nurses were made. Adequate knowledge was confirmed in both the initial and final questionnaires. Application of preventive measures ranged from 11% for hand washing pre-aspiration to 97% for the use of a sterile aspiration probe. The Nine Equivalents of Nursing Manpower Use Score was 50±13. No significant differences were observed between the association of the nurses' knowledge and the application of preventive measures or between workload and the application of preventive measures. CONCLUSIONS: Nurses' knowledge of VAP prevention measures is not necessarily applied in daily practice. Failure to follow these measures is not subject to lack of knowledge or to increased workload, but presumably to contextual factors.

Safety and effectiveness of ustekinumab and antitumour necrosis factor therapy in patients with psoriasis and chronic viral hepatitis B or C: a retrospective, multicentre study in a clinical setting.

BACKGROUND: Both the safety and efficacy of biologic therapy may be affected in the presence of highly prevalent chronic viral hepatitis. OBJECTIVE: To evaluate the safety and effectiveness of ustekinumab and antitumour necrosis factor therapy in patients with psoriasis and concomitant chronic viral hepatitis. METHODS: This was a retrospective, multicentre study. Twenty-five patients with psoriasis and concurrent hepatitis C virus (HCV) (20 patients) or hepatitis B virus (HBV) (five patients) infection who had received at least one biologic agent (etanercept, 21 treatments; adalimumab, four; ustekinumab, four; infliximab, two) were included. Clinical, imaging and laboratory data were recorded. RESULTS: In the case of HCV infection, the majority of the patients did not exhibit increases in their viral load or serum liver tests. Aspartate aminotransferase, alanine aminotransferase and gamma glutamyl transpeptidase were doubled from the baseline measurement in only one patient treated with etanercept. Two other cases exhibited viral load increases during the follow-up period. In total, 18 of the 26 treatments achieved a 75% improvement in their Psoriasis Area and Severity Index (PASI 75) score during the follow-up period. Two patients treated with etanercept were diagnosed with hepatocellular carcinoma. In the case of HBV infection, all of the patients were being treated with antiviral therapy, and none presented significant variations in viral load or serum liver enzymes. All patients achieved a PASI 75 during follow-up. CONCLUSIONS: Biologic therapy was effective and safe for the majority of our patients with HCV and HBV infection, although there may be a risk of reactivation or aggravation. We describe the first cases to receive ustekinumab. The use of biologics should be limited to those cases in which the risk-benefit ratio is justified.

[Initial evaluation, diagnosis, staging, treatment, and follow-up of patients with primary cutaneous malignant melanoma. Consensus statement of the Network of Catalan and Balearic Melanoma Centers]. / Valoración inicial, diagnóstico, estadificación, tratamiento y seguimiento de los pacientes con melanoma maligno primario de la piel. Documento de consenso de la "Xarxa de Centres de Melanoma de Catalunya i Balears"

The consensus statement on the management of primary cutaneous melanoma that we present here was based on selection, discussion, review, and comparison of recent literature (including national and international guidelines). The protocols for the diagnosis, treatment, and follow-up used in the hospital centers throughout Catalonia and the Balearic Isles belonging to the Network of Catalan and Balearic Melanoma Centers were also considered. The main objective of this statement was to present the overall management of melanoma patients typically used in our region at the present time. As such, the statement was not designed to be an obligatory protocol for health professionals caring for this group of patients, and neither can it nor should it be used for this purpose. Professionals reading the statement should not therefore consider it binding on their practice, and in no case can this text be used to guarantee or seek responsibility for a given medical opinion. The group of dermatologists who have signed this statement was created 3 years ago with the aim of making our authorities aware of the importance of this complex tumor, which, in comparison with other types of cancer, we believe does not receive sufficient attention in Spain. In addition, the regular meetings of the group have produced interesting proposals for collaboration in various epidemiological, clinical, and basic applied research projects on the subject of malignant melanoma in our society.

[Lichen planus associated with liver disease caused by hepatitis C virus]. / Liquen plano asociado a hepatopatía por virus de la hepatitis C.

The association between lichen planus (LP) and liver disease by the hepatitis C virus (HCV) has recently been described although its significance is controversial. The charts of 10 patients (8 women, 2 men) clinically and/or histologically diagnosed of LP and with positive HCV serology were retrospectively reviewed. Nine of the patients presented mucosal involvement, four of which were of the erosive form. In 7 patients liver disease preceded the appearance of LP. In the remaining 3 patients HCV infection was detected after the diagnosis of LP despite no alterations being observed in the liver function tests in 2 cases. Alpha-interferon 2b treatment triggered the lesions in 3 cases while leading to resolution of LP in another case. These data confirm the findings referred in the references and support the direct or indirect participation of HCV in LP.

[Cutaneous pigmentation, only manifestation of porphyria cutanea tarda in a HIV-1 positive patient]. / Pigmentation cutanée, seule manifestation d'une porphyrie cutanée tardive chez un malade séropositif pour le VIH1.

INTRODUCTION: Porphyria cutanea tarda (PCT) is an unfrequent disorder in patients with acquired immunodeficiency syndrome (AIDS) due to deficiency in uroporphyrinogen decarboxilase. The more frequent cutaneous manifestations are skin fragility and hypertrichosis. CASE REPORT: A 44-years-old man with AIDS presented an intense cutaneous hyperpigmentation, preferently involving sun-exposed areas. Histopathologic studies showed perivascular PAS-positive deposits. Biochemical studies confirmed the diagnosis of PCT. DISCUSSION: PCT should be included in the differential diagnosis of cutaneous hyperpigmentation in patients infected by human immunodeficiency virus (HIV).

Therapeutic efficacy and safety of the new antimycotic sertaconazole in the treatment of cutaneous dermatophytosis.

7-Chloro-3-[1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)ethoxy-methyl] benzo[b]thiophene (sertaconazole, FI-7045, CAS 99592-32-2) is a new antimycotic which, in experimental infection studies, proved to possess potent antifungal activity. In a randomized, parallel, double-blind trial, the activity of sertaconazole cream was studied in 20 patients suffering from superficial mycoses caused by dermatophytes, confirmed by microscopic examination (KOH) and culture test. The patients, who were included in accordance with microbiological, microscopic and clinical criteria, were divided into two groups of 10 and were treated with sertaconazole 1% or sertaconazole 2% (cream) twice a day for 28 days. Both treatments achieved a total cure of the disease, with a cure being reached in a shorter time in the group of patients treated with sertaconazole 2%. No undesirable effects or statistically significant changes in the blood tests conducted at the end of the trial were observed. The results of the trial show that sertaconazole 2% cream is more effective. In view of the advantages offered by topical therapy over systemic therapy and of the good results obtained in patients with dermatophytosis, sertaconazole may represent an important advance in the therapy of superficial dermatophytoses.

Multi-centre double-blind trial on the efficacy and safety of sertaconazole 2% cream in comparison with miconazole 2% cream on patients suffering from cutaneous mycoses.

The efficacy and tolerance of 7-chloro-3-[1-(2,4-dichlorophenyl)-2- (1H-imidazol-1-yl)ethoxy-methyl]benzo[b]thiophene (sertaconazole, FI-7045, CAS 99592-32-2) 2% dermatological cream in two daily applications compared with miconazole 2% cream in two daily applications were studied on 631 patients suffering from superficial cutaneous mycosis (sertaconazole n = 317, miconazole n = 314), in a double-blind, controlled multicentre trial with parallel groups. The therapeutic efficacy was evaluated by clinical assessment of the improvement of the lesion and symptoms, a microscopic test on the presence of hyphae or mycelia in the affected area and a culture test on the presence of active infection. Tolerance and safety were evaluated by a general blood analysis and interrogation of the patient on adverse effects. The rate of clinical cures for both treatments at the end of the follow-up was 95.6% for sertaconazole and 88.1% for miconazole, with the difference being statistically significant. In the comparative analysis of the actuarial curve, it was observed that the patients treated with sertaconazole were cured earlier and in a higher proportion than those treated with miconazole, with the difference being significant. The negative result of the microscope examination and culture test confirmed the superiority of sertaconazole over miconazole, already after 14 days of treatment. At the end of the follow-up, 98.6% of the patients in the sertaconazole group obtained a negative culture test result, as opposed to 91.7% in the miconazole group, with the difference being highly significant.(ABSTRACT TRUNCATED AT 250 WORDS)

Prolonged remission after cyclosporine therapy in pemphigus vulgaris: report of two young siblings.

We report the clinical evolution of two young siblings with severe pemphigus vulgaris treated with cyclosporine for 30 and 12 months, respectively. One was resistant to treatment with high-dose corticosteroids and azathioprine. A good clinical response was achieved in both cases. No major side effects were observed. The patients have remained disease free for more than 20 months after stopping cyclosporine therapy.

Reactive perforating collagenosis in Hodgkin's disease.

Two patients with Hodgkin's disease developed a condition that has been termed "reactive perforating collagenosis." In both cases, pruritus was severe and seemed to be responsible for the vigorous rubbing and scratching that caused the skin lesions. In one patient, the lesions disappeared upon remission of Hodgkin's disease. Perforating collagenosis has been described in children as a hereditary disease, and has also been described in adults with diabetes and on hemodialysis. On the basis of the changes seen in our two patients with Hodgkin's disease, we suggest that perforating collagenosis is simply a consequence of intense scratching.

[Anderson-Fabry disease. Current status. Apropos of a case]. / Enfermedad de Anderson-Fabry. Situación actual. A propósito de un caso.

After submitting a typical case of Anderson-Fabry disease in a 38 years old male, we discuss the eminent aspects of this metabolic disorder and, above all, the clinical, biochemical and ultrastructural problems of diagnosis in the heterozygotic relatives.

Blisters over burn scars in a child.

We present the case of an 11-month-old baby with a burn that healed normally over a month, but subsequently developed successive crops of blisters over the scar. There were no changes in his general condition. Clinical, immunological, histological and ultrastructural studies provided a diagnosis of mechanical dermatitis produced by microtrauma. Electron microscopy studies revealed the sub-epidermal nature of the blisters and the presence of underlying fibrin deposits.

The OFDS and kidney polycystic disease is a rare association. Only 7 cases we have been able to find in several references. A new female case with hypertension is reported.

[Dermatitis caused by Milwaukee braces]. / Dermatitis por Milwaukees.

The results of the study of 51 patients bearing a Milwaukee corset indicate that they present a mechanical and irritative dermatitis caused by the personal predisposition, the action of the plastic material and the occlusion and humidity produced between skin surface and the corset. The authors suggest the name Occlusive Dermatitis Syndrom for this cases as a subtype of Mechanical Irritative Dermatitis.

[Acromelanosis and Wilms' tumor]. / Acromelanosis y tumor de Wilms.

Wilms tumour and Acromelanosis is a rare association. The authors describe two white cases, and they believe is an accidental a association. However, it's possible that Acromelanosis was a paraneoplastic sign if the future carry most similar cases.

[Postoperative synergistic progressive gangrene]. / Gangrena sinergística progresiva postoperatoria

A case of synergistic postoperative progressive gangrene is presented. After a bibliographic review and a description of the main clinical chacteristics of the condition, the authors emphasize the fact that tests for cell mediated immunity showed slight impairment. Howeves the immediate type sensitivity tests and the leucocyte function were normal. The patient was treated successfully with fusidic acid after other antibiotics had proved ineffective.
