In patients less than 50 years temporal artery vasculitis is extremely rare. The clinical presentations of the vasculitis in younger patients appear to be different from the older patients. We present two case reports of temporal artery vasculitis in patients less than 50 years, one of them with human immunodeficiency virus infection. Both the cases had variable clinical presentations and good response to treatment.

Barrier system has dunes, vegetated zones, and swampy terrains that extend lagoon wards from the beach. They occupy 13% of the world‟s coastlines (Sikora and Kjerfve 1985) and are found along every continent including the Antarctica. The Coastal Barrier Resources Act (CBRA) of 1982 delineate a coastal barrier as all related aquatic habitats, including the adjacent swampland, marshes, estuaries, inlets and near shore waters, although these natural features have an inverse relationship with few manmade structures or activities which do not drastically encumber geomorphic and ecological processes. A coastal barrier can either be developed or undeveloped; this is related to the density of development and availability of infrastructure on the land above mean high tide. (CBRA, 1982). Lagos is located at the Western tip of the coastline of Nigeria. ...

The predominant impact has been on coastal communities with huge losses of life, livelihoods, property, and infrastructure. This paper explores the alternative means of livelihood in badagry littoral communities. Badagry is a typical sand barrier-lagoon coastal community with a population of 119,267 people and is characterised by 80km of unspoilt beaches fronting the Atlantic Ocean. The livelihood of these littoral people is dependent primarily on agricultural activities which environmental phenomena are causing accelerated rates of erosion and flooding, and as a result have direct effects on the livelihood pattern. This study recognizes participatory research as a viable physical planning tool for community base tourism enterprise. Relevant primary data was obtained through a combination of two participatory research techniques including structured interviews and personal observation, and mapping using GIS as a design tool. Previous research works on coastal erosion in Nigeria, marine ecosystem and Lagos State regional master plan provides relevant secondary data. The paper found out that the coastal process is recently made worse by the climate change powered ocean surge. The ecosystem is sparse coastal vegetation, holding together loose sandy soil formation along the Atlantic shoreline. The research concludes and recommends that the combination of the ministry of environment and ministry of physical planning and urban development should adopt a guideline policy and principles to emphasize on indigenous architecture for all cabins; unique linkage to the artisanal, fishing occupation; and conservation of native flora as ecological engineering approach to reduce ocean surge threats.

Shifting attention from automobile transportation mode must evolve policies driven by the principles of cities for pedestrians and cyclists. This study explored ecofriendly streetscape to incorporate cycling as non-motorized transportation alternative in metropolitan Lagos. The paper is underpinned by the Community Cycling Accessibility Initiative conceptual framework. The research methodology adopted a baseline study of selected streets from selected local government areas. Four streets representing the three broad hierarchies of city roads (highway, arterial, collector and local streets) were selected. Inventory of street spaces was conducted to record existing resources. Emphasis was laid on width of right of way, paved surface, kerb, street trees, outdoor communication media and street furniture. The study identified irregular property fence lines; silted open drainage system; non-separation of different transportation modes; uncoordinated street furniture; street trading; and street parking as negative impacts on the right of way. Two categories of bicycle roads namely on road bicycle track and on road bicycle and pedestrian track separated from vehicular lane were introduced to revitalize selected metropolitan streets as urban design case study. These two categories should be influenced by internationally acclaimed and tested (4Es) bicycle planning philosophy namely engineering, education, enforcement and encouragement. The paper recommends that the Lagos Metropolitan Area Transport Authority (LAMATA) should provide adequate bicycle policies as practical guide to sustainable non-motorized transportation mode in the metropolis.
