RESUMO

PURPOSE: Poor response to bariatric surgery, namely insufficient weight loss (IWL) or weight regain (WR), is a critical issue in the treatment of obesity. The purpose of our study was to assess the efficacy, feasibility, and tolerability of very low-calorie ketogenic diet (VLCKD) for the management of this condition. METHODS: A real-life prospective study was conducted on twenty-two patients who experienced poor response after bariatric surgery and followed a structured VLCKD. Anthropometric parameters, body composition, muscular strength, biochemical analyses, and nutritional behavior questionnaires were evaluated. RESULTS: A significant weight loss (mean 14.1 ± 4.8%), mostly due to fat mass, was observed during VLCKD with the preservation of muscular strength. The weight loss obtained allowed patients with IWL to reach a body weight significantly lower than that obtained at the post-bariatric surgery nadir and to report the body weight of patients with WR at the nadir observed after surgery. The significantly beneficial changes in nutritional behaviors and metabolic profiles were observed without variations in kidney and liver function, vitamins, and iron status. The nutritional regimen was well tolerated, and no significant side effects were detected. CONCLUSION: Our data demonstrate the efficacy, feasibility, and tolerability of VLCKD in patients with poor response after bariatric surgery.

RESUMO

BACKGROUND: Treatment for cellulite above the knees is increasingly requested. However, a classification of cellulite of this area has not yet been developed. OBJECTIVE: To validate the proposed knee cellulite severity score (KCSS) for the assessment of cellulite and skin laxity above the knee. MATERIALS AND METHODS: Based on standardized photographs of cellulite and skin laxity above the knees of 57 females (114 knees), three key morphological aspects of cellulite were identified. A photonumeric KCSS was developed and validated by three independent assessors. RESULTS: The three key cellulite morphological features (number of depressions, depth of depressions and presence of laxity) are each graded from 0 to 3, producing a classification of no lesions (0), mild (1-3), moderate (4-6) and severe (7-9). Evaluators at different time points repeated similar classifications (intraclass correlation coefficient >0.9), which were also similar among the assessors (inter-observer reliability >0.9). All three key morphological aspects were deemed necessary, and positively contributed, to the overall scale (item-total correlation analysis values >0.89, P < 0.05). CONCLUSIONS: The KCSS is a consistent, comprehensive, reliable, and reproducible tool for standardized and objective assessment of the severity of cellulite and skin laxity above the knees.

RESUMO

BACKGROUND: Imiquimod 3.75% cream (Zyclara® Meda, Stockholm, Sweden) is a new field-directed therapy for actinic keratosis (AK). OBJECTIVES: The aim is to evaluate efficacy and the morphologic dynamic changes induced by this treatment by means of dermatoscopy and reflectance confocal microscopy (RCM) of imiquimod 3.75% cream for the treatment of AKs of the face or scalp and to evaluate. METHODS: Thirty-two patients were treated with Imiquimod 3.75% cream. Demographic parameters, AK-FAS and AKASI scores and side-effects were collected. RCM and dermatoscopy on one target AKs were performed at each visit. We collected images at baseline (T0), after 1 week from the end of the first 2-week cycle (T1), after 1 week from the end of the entire treatment (T2) and 2 months after the end of treatment (T3). RESULTS: One target representative AK in the selected area of treatment of each patient was analysed. All dermoscopic and confocal parameters were reduced 2 months after the end of the therapy (T3) with a substantial reduction of AKASI and AK-FAS scores, and 17 cases (54.8%) were completely solved. Confocal microscopic analysis showed a reduction of keratinocytes disarray in 77.4% of cases; none showed crusts and parakeratosis. Inflammation was considerably decreased and was observed only in 12.9% of patients at the last visit. This improvement was not assessed on dermatoscopy because of inflammation and background erythema, which adversely influenced the assessments. LSRs were observed in almost all the patients during treatment being more severe after the first cycle of treatment (T1). CONCLUSIONS: Imiquimod 3.75% cream is effective in treating clinical and subclinical AKs with an easy management of side-effects. Dermatoscopy and mostly RCM allow non-invasive monitoring of treatment response in vivo.

RESUMO

BACKGROUND: In vivo reflectance confocal microscopy significantly improves melanoma diagnosis as compared to clinical/dermoscopic examination alone. Several confocal criteria have been described allowing to differentiate melanoma from nevi; by combining different criteria, three pure confocal scores (Pellacani 2005, Segura 2009 and Pellacani 2012) and one mixed dermoscopic/confocal score (Borsari 2018) were constructed. OBJECTIVE: Our aim was to externally validate and compare the performance of these confocal scores. METHODS: We retrospectively enrolled excised melanocytic lesions which underwent confocal examination in a 2-year period. Lesions located on the face and acral sites were excluded. Both dermoscopic and confocal criteria considered in the four scores were evaluated by experts. Subsequently, specificity and sensitivity levels for each score were calculated, together with the positive and negative predictive values and likelihood ratios; also, receiver operating characteristic curves were constructed. RESULTS: A total of 389 patients with 422 lesions were retrospectively enrolled, of which 162 (38.4%) were melanomas and 260 (61.6%) were nevi (189 common and 71 Spitz/Reed nevi). The highest sensitivity levels were recorded for Segura 2009 with cut-off ≥-1 (92.0%), while Pellacani 2005 with cut-off ≥5 achieved the highest specificity (69.6%). The score by Borsari et al. showed the highest levels of positive and negative predictive values (59.8% and 91.5%) and likelihood ratios (2.4 and 0.1) as well as the highest area under the curve values (0.76; 95% CI 0.72-0.81; P < 0.001). CONCLUSIONS: High levels of accuracy were found for each of the four considered scores. No differences were found among scores in confirming melanoma diagnosis when positive; however, the score by Borsari 2018 was the best in excluding melanoma diagnosis when negative.

RESUMO

BACKGROUND: Cutaneous malignant melanoma metastases differential diagnosis is challenging, as clinical and dermoscopic features can simulate primary melanoma or other benign or malignant skin neoplasms, and in-vivo reflectance confocal microscopy could assist. Our aim was to identify specific reflectance confocal microscopy features for cutaneous malignant melanoma metastases, and epidermal and dermal involvement. METHODS: A retrospective, multicentre observational study of lesions with proven cutaneous malignant melanoma metastases diagnosis between January 2005 and December 2016. Lesions were retrospectively assessed according to morphological features observed at reflectance confocal microscopy. Potential homogeneous subgroups of epidermal or dermal involvement were investigated with cluster analysis. RESULTS: Cutaneous malignant melanoma metastases (51 lesions in 29 patients) exhibited different frequencies of features according to metastasis dermoscopy patterns. Lesions classified at dermoscopy with nevus-like globular and non-globular patterns were more likely to be epidermotropic, showing characteristics of epidermal and dermal involvement at reflectance confocal microscopy. Other dermoscopy pattern classifications were more likely to be dermotropic, showing characteristics od dermal involvement at reflectance confocal microscopy. Distinguishing features at reflectance confocal microscopy included irregular (78%) and altered (63%) epidermis, pagetoid infiltration (51%), disarranged junctional architecture (63%), non-edged papillae (76%), dense and sparse, and cerebriform nests in the upper dermis (74%), and vascularity (51%). Cluster analysis identified three groups, which were retrospectively correlated with histopathological diagnoses of dermotropic and epidermotropic diagnoses (P < 0.001). The third cluster represents lesions with deep dermis morphological changes, which were too deep for evaluation with reflectance confocal microscopy. CONCLUSIONS: Specific reflectance confocal microscopy features of cutaneous malignant melanoma metastases for correct diagnosis, and subtype diagnosis, seem achievable in most cases where morphological alterations are located above the deep dermis.

RESUMO

BACKGROUND AND AIMS: Diabetic women have a more adverse plasma lipid profile than men. Sex differences in dietary habits may play a role, but are little investigated. The study evaluates the quality of diet, adherence to the nutritional recommendations of the Diabetes and Nutrition Study Group and their relation with plasma lipid in men and women with diabetes. METHODS AND RESULTS: We studied 2573 people, aged 50-75, enrolled in the TOSCA.IT study (clinicaltrials.gov; NCT00700856). Plasma lipids were measured centrally. Diet was assessed with a semi-quantitative food frequency questionnaire. Women had a more adverse plasma lipid profile than men. Women consumed significantly more legumes, vegetables, fruits, eggs, milk, vegetable oils, and added sugar, whereas men consumed more starchy foods, soft drinks and alcoholic beverages. This stands for a higher proportion (%) of energy intake from saturated fat and added sugar (12.0 ± 2.4 vs 11.5 ± 2.5 and 3.4 ± 3.2 vs 2.3 ± 3.2, P < 0.04), and a higher intake of fiber (11.2 ± 2.8 vs 10.4 ± 2.6 g/1000 Kcal/day) in women. Adherence to the recommendations for saturated fat and fiber consumption was associated with significantly lower LDL-cholesterol regardless of sex. Adherence to the recommendations for added sugars was associated with significantly lower triglycerides and higher HDL-cholesterol in men and women. CONCLUSIONS: Men and women with diabetes show significant differences in adherence to nutritional recommendations, but sex differences in plasma lipid profile are unlikely to be explained by nutritional factors. Adherence to the nutritional recommendations is associated with a better plasma lipid profile regardless of sex, thus reinforcing the importance of substituting saturated for unsaturated fat sources, increasing fiber and reducing added sugar intake.

RESUMO

With the introduction of biomarkers like troponin I (cTnI), our ability to identify and quantify myocardial infarction in the postoperative period has been greatly enhanced. Even small elevations of cTnI should be considered as a myocardial infarction. Small increases in cTnI postoperatively have indeed been found to be associated with worse short and long-term outcomes, the higher the cTnI level the worse the outcome. Studies undertaken in the 1980s when postoperative myocardial infarction (PMI) was detected by means of electrocardiogram recordings every 12 hours following operation suggested that this complication occurred on the second or third postoperative day. More recent studies where postoperative myocardial necrosis has been detected by repeated troponin dosages have revealed that, in fact, postoperative myocardial infarction appears much earlier between 12 and 32 hour after the end of surgery. Two types of PMI were identified based on intense troponin surveillance. They stem from two different major pathophysiological mechanisms. One seems to be related to plaque-vulnerability, while the other may be due to the effects of prolonged ischemia. The postoperative period should be regarded as a vulnerable period' that acts synergistically with both plaque and patient vulnerabilities in the development of PMI. Monitoring troponin levels in the postoperative period following surgery enables the identification of patients with myocardial damage and the institution of early aggressive intervention (e.g., intensive beta blockers therapy, adequate analgesia, correction of anemia) in order to prevent the evolution of PMI during this golden period' that lasts about two days. In patients that are prone to develop PMI, and especially in those who are prone to develop PMI related to plaque rupture, prevention can be achieved by better preoperative identification of the vulnerable plaque, and by a better plaque stabilization, either metabolically (e.g., statins) or by actual coronary stenting. Further understanding of the mechanisms underlying PMI, as well as their early identification, may contribute to the reduction of the incidence of PMI and its associated morality in the future.
