Although the results were based on a small series, placement of stents in the pediatric airway to treat tracheobronchial obstruction seems to be safe and effective. Stenting is a satisfactory therapeutic option when other procedures have failed or are not indicated.
Background
The two main tumors treated with Mohs micrographic surgery (MMS) are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). There are no studies analyzing whether MMS is different when treating these two types of tumors.
Objective
We aim to compare the characteristics of the patients, the tumors, and MMS, and first‐year follow‐up of MMS in BCC and SCC.
Methods
REGESMOHS is a prospective cohort study of patients treated with MMS. The participating centers are 19 Spanish hospitals where at least one MMS is performed per week. Data on characteristics of the patients, tumors, and surgery were recorded. The follow‐up was done with two visits: the first visit within 1 month after surgery and the second one within the first year.
Results
From July 2013 to April 2017, a total of 2,669 patients who underwent MMS were included in the registry. Of them, 2,448 (93%) were diagnosed with BCC, and 181 (7%) were diagnosed with SCC. Patients with SCC were older than those with BCC (median age 73 years vs. 68 years) and presented immunosuppression more frequently. The tumor size was significantly larger in the SCC group. Regarding surgery, deeper invasion was more frequent in SCC, resulting in larger defects. Despite this, SCC did not require more stages to get clear margins or more time in the operating room. Incomplete Mohs was more frequent in the SCC group (6%) than in the BCC group (2%). The incidence of perioperative complications was higher when treating SCC. There were more relapses in the first‐year follow‐up in the SCC group.
Conclusion
There are significant differences when comparing MMS in BCC and SCC. Knowledge of these differences can help to prepare the patient and plan the surgery, optimizing results.
Fistulae between esophagus and major arteries are an extremely rare and severe condition. They have been described in patients with previous impairment or abnormalities of mediastinal vessels and intraesophageal increased pressure or as a complication of cardiovascular procedures. We report three cases of children with an aorto-esophageal fistula, a collateral pulmonary artery-esophageal fistula and an aberrant right subclavian artery-esophageal fistula that were successfully managed in coordination with pediatricians, anesthesiologists and both cardiovascular and pediatric surgeons. The severity of this pathology makes it important to suspect it and treat it by a multidisciplinary group of physicians.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
