BACKGROUND Obesity is one of the leading causes of preventable death worldwide. Due to its increasing incidence and the difficulty in reducing its morbidity and mortality using nonsurgical methods, the demand for bariatric surgery has risen in recent times. Sleeve gastrectomy is one of the most common types of bariatric surgery, and like any other surgery, it carries a series of risks. CASE REPORT Although complications such as gastrointestinal leaks are widely reported, there is limited literature available on cutaneous complications. Here, we report 4 cases of patients showing a peculiar skin rash 2-4 weeks following sleeve gastrectomy. We also discuss some of the mechanisms that may underlie this correlation. CONCLUSIONS There is a need for further epidemiological studies to determine the prevalence of this rash. Further studies are also needed to determine the exact etiology of this rash.

Hypertension (HT) is considered to be a potential risk factor for cardiovascular diseases and has been directly related to pathologies such as obesity and dyslipidemias. Angiotensin-converting enzyme inhibitors (ACEIs) blocked the renin-angiotensin-aldosterone cascade diminishing the production of angiotensin II and the level of bradykinin, produced by the kallikrein-kinin system. Although ACEIs are effective therapeutics in regulating HT, they present several side-effects that can be due to their mechanism of action (as hypotension, cough, dizziness, light-headedness or hyperkalemia) to specific drug molecular structure (skin rash, neutropenia and tasting disorders) or due to associated pathologies in the patients (it has been considered a possible nephrotoxic effect when ACEIs are administered in combination with angiotensin receptor blockers, in patients that present comorbidities as diabetes, acute kidney injury or chronic kidney disease). Therefore, it is necessary the searching for new products with ACEI activity that do not produce side effects. Interestingly, species of the plant genus Salvia have been found to possess hypotensive effects. In the present study, we analyzed the effects of the ethanolic extract of Salvia hispanica L. seeds (EESH) on the expression of genes involved in pathways regulating HT. Administration of EESH to hypertensive rats inhibited the angiotensin-converting enzyme (ACE) activity along with a decrease in Ace and elevation of Agtr1a and Nos3 gene expression, as compared to that in healthy rats. Moreover, these results were similar to those observed with captopril, an antihypertensive drug used as a control. No significant change in the expression of Bdkrb2 gene was observed in the different groups of rats. To conclude, our results demonstrate that EESH regulates blood pressure (BP) in hypertensive rats through transcriptionally regulating the expression of genes that participate in different pathways involving ACE.

Confluent and reticulated papillomatosis (CARP), a rare dermatologic disorder characterized by hyperpigmented papules that subsequently develop into plaques with reticulated margins, is frequently confused with acanthosis nigricans. The aetiology and pathogenesis of CARP is not yet fully understood, but it is often present in individuals with obesity and PCOS. This case report describes an African American adolescent female with obesity with a rash diagnosed as CARP after unsuccessful treatment with antifungals and corticosteroids. Her dermatosis proved recalcitrant to antibiotics and metformin but started to resolve immediately after bariatric surgery. This case report supports insulin resistance as a contributor to CARP's pathogenesis and as well as its association with obesity. Clinically significant weight reduction should be considered in the management of this challenging skin condition.
