Στην βιολογία, το περιβάλλον μπορεί να καθοριστεί σαν ενα σύνολο κλιματικών, βιοτικών, κοινωνικών και εδαφικών παραγόντων που δρουν σε έναν οργανισμό και καθορίζουν την ανάπτυξη και την επιβίωση του. Έτσι, περιλαμβάνει οτιδήποτε μπορεί να επηρεάσει άμεσα τον μεταβολισμό ή τη συμπεριφορά των ζωντανών οργανισμών ή ειδών, όπως το φως, ο αέρας, το νερό, το έδαφος και άλλοι παράγοντες.

Στην αρχιτεκτονική, την εργονομία και την ασφάλεια στην εργασία, περιβάλλον είναι το σύνολο των χαρακτηριστικών ενός δωματίου ή κτιρίου που επηρεάζουν την ποιότητα ζωής και την αποδοτικότητα, περιλαμβανομένων των διαστάσεων και της διαρρύθμισης των χώρων διαβίωσης και της επίπλωσης, του φωτισμού, του αερισμού, της θερμοκρασίας, του θορύβου κλπ. Επίσης μπορεί να αναφέρεται στο σύνολο των δομικών κατασκευών. Δείτε επίσης το άρθρο για το δομημένο περιβάλλον.
Στην ψυχολογία, περιβαλλοντισμός είναι η θεωρία ότι το περιβάλλον (με τη γενική και κοινωνική έννοια) παίζει μεγαλύτερο ρόλο από την κληρονομικότητα καθορίζοντας την ανάπτυξη ενός ατόμου. Συγκεκριμένα, το περιβάλλον είναι ένας σημαντικός παράγοντας πολλών ψυχολογικών θεωριών.
Στην τέχνη, το περιβάλλον αποτελεί κινητήριο μοχλό και μούσα εμπνέοντας τους ζωγράφους ή τους ποιητές. Σε όλες τις μορφές της Τέχνης αποτελεί έμπνευση και οι Καλές Τέχνες φανερώνουν την επιρροή οπού άσκησε σε όλους τους καλλιτέχνες με όποιο είδος Τέχνης κι αν ασχολούνται. Ο άνθρωπος μέσα στο περιβάλλον δημιουργεί Μουσική, Ζωγραφική, Ποίηση, Γλυπτική, χορό, τραγούδι, θέατρο, αλλά και όλες οι μορφές τέχνης έχουν άμεση έμπνευση από το περιβάλλον.

Aesthetic Outcomes of Nasal Burow's Grafts With Interdomal Sutures After Mohs Micrographic Surgery
BACKGROUND Post-Mohs reconstruction of distal nasal defects is challenging. Many repair options exist, each with advantages and disadvantages. Utilization of a Burow's graft in combination with manipulation of the underlying nasal cartilages with interdomal sutures is an underreported yet effective repair option. OBJECTIVE To present the authors' experience with Burow's grafts facilitated by interdomal sutures for repair of nasal defects after Mohs micrographic surgery (MMS). MATERIALS AND METHODS Patients who underwent repair with Burow's grafts and interdomal sutures from 2013 to 2017 at a single university were identified. Demographics, follow-up, and complications were recorded. Two independent, board-certified dermatologists evaluated photographs for cosmesis and alar symmetry. RESULTS Thirty-one patients were identified. A total of 5/31 patients (16.1%) experienced minor complications without permanent sequelae. A total of 4/31 (12.9%) patients underwent cosmetic revision. No incidences of pincushioning, nasal valve dysfunction, or graft necrosis occurred. Aesthetic ratings were good to excellent with mean visual analog score of 80.8. Alar symmetry was excellent. CONCLUSION A Burow's full-thickness skin graft facilitated by an interdomal suture to maintain nasal tip orientation and projection is an elegant repair technique for distal nasal oncologic defects with good to excellent aesthetic outcomes. It should be considered in the armamentarium for repair of distal nasal defects after MMS. Address correspondence and reprint requests to: Michael W.

Primary Cutaneous Umbilical Melanoma: The Michigan Experience
BACKGROUND Primary cutaneous umbilical melanoma is rare. Thorough information regarding its characteristics and treatment, including use of sentinel lymph node biopsy (SLNB) staging, is difficult to obtain. The unique anatomy of the umbilicus adds to the complexity of diagnosing and treating melanoma at this site. OBJECTIVE To improve understanding of diagnosis and treatment of primary cutaneous umbilical melanoma through presenting 7 new cases and reviewing 39 cases in the literature. MATERIALS AND METHODS The University of Michigan melanoma database query and review of the literature regarding reported cases of primary umbilical melanoma. RESULTS In 7 new and 39 previously reported cases of primary cutaneous umbilical melanoma, we describe signs and symptoms, histopathologic features, differential diagnosis, relevant anatomical considerations, and definitive treatment including SLNB when applicable. CONCLUSION Our series, combined with a thorough literature review and compilation of findings, provides a better understanding and appreciation of melanoma in the unique anatomical site of the umbilicus, with a reminder to carefully examine the umbilicus during a full skin examination in patients at risk of melanoma. Primary umbilical melanoma presents and can be appropriately treated similarly to cutaneous melanoma in other sites, with attention to relevant anatomy.

Cutaneous Leiomyosarcoma: A SEER Database Analysis
BACKGROUND Cutaneous leiomyosarcoma is a rare dermal neoplasm usually arising from the pilar smooth muscle. It is considered a relatively indolent neoplasm, and there is debate whether designation as sarcoma is appropriate. Owing to some conflicting data in the literature, however, its behavior warrants further clarification. OBJECTIVE To determine the clinical behavior and demographic and pathologic characteristics of cutaneous leiomyosarcoma. MATERIALS AND METHODS The Surveillance, Epidemiology and End Results database was used to collect data on cutaneous leiomyosarcoma and 2 reference populations: cutaneous angiosarcoma (aggressive) and atypical fibroxanthoma (indolent). Demographic and oncologic characteristics were examined, and overall survivals (OS) and disease-specific survivals were compared. RESULTS Leiomyosarcoma and atypical fibroxanthoma displayed lower stage (localized: 69.7% and 66.8% respectively), smaller size (<3 cm: 90.5% and 72%), and lower rates of disease-specific mortality (2.9% and 7.8%) compared with angiosarcoma. Patients with leiomyosarcoma had a 5-year disease-specific survival rate of 98% and OS rate of 85%. CONCLUSION Cutaneous leiomyosarcoma shows outcomes similar to atypical fibroxanthoma. It is nearly always indolent and should be distinguished from more aggressive cutaneous and subcutaneous sarcomas. Clear communication of the biologic potential may be best achieved using alternate diagnostic terminology such as "atypical intradermal smooth-muscle neoplasm."
