This study was used to assess public opinion of the economic and ecological importance of various tree species in Kaduna Metropolis, Kaduna state. A total of one hundred (100) questionnaires were randomly administered among four purposively selected towns (Angwa-Rimi and Kawo new extension in Kaduna North and Bar’nawa and Sabo in Kaduna South) within the two major local governments in the study area. Twenty-five (25) questionnaires were randomly distributed across age and sex in each of the four (4) selected towns. Of these, ninety were retrieved for analysis. Data analysis was achieved through descriptive analysis. This included frequency distribution tables, percentages and charts. The results show that the majority of the respondents were aged between (21-30) and (31-40) years, these figures representing (44.4%) and (30.0%), respectively, of the entire study population. In addition, most had secondary education (53.3%). In the stated opinions, Meliaceae occur most often. Other trees species identified in the study area include Eucalyptus spp, Azadiracta indica, Psidium guajava, Terminalia catapa, Mangifera indica, Anacardium occidentalis, Khaya senegalensis, Gmelina arboria, pinus spp, Carica papaya, Moringa olifera, Gliricidia sepium, Ficus spp, Afzelia spp, Balanite eagyptiaca, Borassus aethiopum, Persae americana, Polyantha longifolia etc. The following characteristics mark these tree species out as being economically and ecologically important: fast growth, deep rooting pattern, coppicing ability, ability to produce large crown size, tolerance to adverse weather condition, ability of trees to produce broad leaves for shade production, erosion protection, ability to provide fruits, aesthetics and beautification values. In conclusion, urban tree planting is a potential strategy to ameliorate ecological and economic concerns; thus, there is need for the dwellers in the study area to intensify efforts towards planting trees around their houses. Without this, the influx of people, urbanization and industrialization will create deleterious environmental conditions in the study area. It is recommended that efforts to make the populace aware of the economic and ecological significance of urban trees be intensified.

Introduction: A Polish National Major Salivary Gland Benign Tumors Registry (SGR) is a report of benign salivary gland neoplasms (SGNs) from 26 different centres in Poland, introduced in 2014. The aim of this study is to analyze demographic characteristics and clinico-pathological factors of benign SGNs treated in large tertiary institutions and to determine possible correlations between selected variables. Material and method: Analysis of 585 patients recorded in SGR and operated on for SGNs in the Department of Otolaryngology and Laryngological Surgery, University of Medical Sciences, Poznań, Poland, over a 5-year period. Patient age, sex, occupation, place of residence, tumor location, size, histology, recurrence, facial nerve function after surgery, wound healing, surgery procedure, availability of pre-operative imaging examinations, fine-needle aspiration cytology (FNAC) results were analyzed. Results: 338 females and 247 males with a mean age of 53 years were operated on. In total, 96.2% of tumors originated from the parotid and 3.8% from the submandibular gland. The most frequent primary tumor diameter was 2–4 cm (59.5%) followed by <2 cm (29.2%) and >4 cm (8.4%). Tumors of over 4 cm were frequently removed by partial superficial parotidectomy, while those under 2 cm – by extracapsullar dissection (ECD). Pleomorphic adenomas (PA) were predominant (58.8%), followed by Warthin’s tumor (WT) – 37.1%. Patients with WT were on average 13.3 years older than patients with PA. Discussion: This research can be helpful to better understand the clinico-pathological features of SGNs. Long-termin hospital-based analysis is important for subsequent metaanalyses and comparisons with other centers. The reasons why not all patients’ data are reported to the national SGR should be further precisely analyzed.
