This prospective study aimed to determine the manometric pattern and the prevalence of esophageal dysmotility in 79 morbidly obese patients selected for laparoscopic sleeve gastrectomy. After clinical evaluation and upper gastrointestinal endoscopy, high-resolution esophageal manometry was performed. The esophageal peristalsis, lower esophageal sphincter (LES) basal pressure, and LES relaxation were evaluated. Demographic data showed a predominance of females (55.70%) and both females and males were in the 5(th) decade of life. In addition, approximately 3/4 of the patients (78.48%) were from the urban zone. The mean body mass index of the patients was 46.40±6.0069 kg/m(2), with a maximum of 61 kg/m(2). The LES basal pressure was normal in 59.49% of the patients, with a mean value of 31.40±18.43 mmHg. LES basal hypertonia was observed in 26.58%, and LES hypotonia in 13.93% of patients; 46.84% (37 patients) had abnormal manometric findings: 24.05% (19 patients) had EGJ outflow obstruction, 12.66% (10 patients) ineffective esophageal motility, 3.8% (3 patients) distal esophageal spasm, 3.8% (3 patients) Jackhammer esophagus, 2 cases were suggestive for type 2 achalasia but in asymptomatic patients. Ineffective esophageal motility was not associated with diabetes mellitus type 2 or erosive esophagitis according to our data. Hiatal hernia (HH) was manometrically diagnosed in 23 patients (29.11%). Preoperative high-resolution esophageal manometry in obese patients demonstrated a high prevalence of motility disorders, but in asymptomatic patients, thus in the future, we require more studies and larger cohorts to better appreciate the clinical impact.

An early diagnosis is of overwhelming importance for the management and prognosis of mucocutaneous cancer. Actinic cheilitis (AC), defined by the clonal expansion of genomically unstable keratinocytes, is the most common potentially malignant lesion affecting the lips. Squamous cell carcinoma (SCC) is the most frequent oral malignancy, and there is strong evidence that the majority of the SCCs of the lip originate from AC. There is considerable difficulty in discerning between dysplasia and invasive carcinomas solely on a clinical basis. Although dermoscopy has become an essential tool for skin tumor evaluation, reflectance confocal microscopy (RCM) is a non-invasive imaging technology that has proved itself extremely useful in the diagnosis and monitoring of several skin diseases, including AC and SCC. The present study aimed to re-emphasize the usefulness of RCM in the early detection of malignant transformation, using AC and SCC of the lips as working examples. Due to the apparent innocuousness of AC for numerous patients, it is not possible to overstress the importance of a correct and early diagnosis, proper treatment and long-term patient follow-up as being essential for preventing the progression to lip SCC, or for its timely diagnosis.

Superficial basal cell carcinoma (sBCC) is the second most frequent histological type of basal cell carcinoma (BCC), usually requiring a skin biopsy to confirm the diagnosis. It usually appears on the upper trunk and shoulders as erythematous and squamous lesions. Although it has a slow growth and seldom metastasizes, early diagnosis and management are of crucial importance in preventing local invasion and subsequent disfigurement. Dermoscopy is nowadays an indispensable tool for the dermatologist when evaluating skin tumors. Reflectance confocal microscopy (RCM) is a novel imaging technique that allows the non-invasive, in vivo quasi-microscopic morphological and dynamic assessment of superficial skin tumors. Moreover, it offers the advantage of performing infinite repeatable determinations to monitor disease progression and non-surgical treatment for sBCC. Herein, we present three lesions of sBCC evaluated using in vivo and non-invasive imaging techniques, emphasizing the usefulness of combining RCM with dermoscopy for increasing the diagnostic accuracy of sBCC.
