EPIDEMIOLOGY OF COCCIDIOIDOMYCOSIS

EPIDEMIOLOGY OF COCCIDIOIDOMYCOSIS

Background: Clinical Description

The disease causing agent, Coccioides spp., causes a wide range of illness, but these illness are mostly determined by the hosts' defenses, inoculum size and possibly specific organism virulence. Most of the clinical infections (about 60%) show few or no respiratory symptoms. However, the rest 40% may show symptoms of illness that may either be acute or sub-acute. The illness could range from progressive pneumonia to flu-like conditions. Misdiagnosis usually occurs in self-limited community-acquired pneumonia. According to Saubolle, McKeller & Sussland (2007), only 29% of 56 people who had community-acquired pneumonia were diagnosed of coccidioidomycosis. The exact ...

Introduction

A quarry is like an open pit mine from where minerals are extracted that are mostly used in the construction of buildings and civil engineering works. Quarrying is a part of mining but is slightly different as it has a close connection with the society because different builder of a region requires material that is extracted in order to complete their work. There are not many restrictions for quarrying as it is open for all the contractors. Due to this reason all the managers and developers at different levels need to ...

The mechanistic structure comprises a bureaucratic or hierarchical arrangement with formalised practices or procedures along with centralised authority and focuses on control and specialisation. Mechanistic structures are rigid and excessively authoritative with emphasis on power and chain of command. Conversely, organic structures are more flexible, open, and informal as compared to mechanistic structures and encourage employee involvement and input. Organic structures are more practical as compared to mechanistic structures in a rapidly changing business environment of the modern world mainly because of the flexibility. The mechanistic structures offset the creativity, flexibility, and autonomy required in the contemporary world to ...

INTRODUCTION

Many countries rely on agricultural crops for the food security of their citizens and the stability of their economy. Cultivating crops allowed humans to meet their increasing demands for crops and continue to prosper. Without agricultural products, civilizations would have been different or would have failed to exist. People would have relied on gathering crops and end up exhausting every available resource there is. Nevertheless, as societies and their demands for agricultural crops advance, more strain are put into the environment. People have cultivated crops continuously and some have done it without much regards to the environment. There have ...

Indirect problems of the quarrying include the calamities that can cause greater damages such as through land sliding and flash floods. Major negative effects of ...

BT an 8 year old boy was presented for check-up after developing nasal congestion, sneezing and coughing. According to her mother, the boy has been developing these symptoms regularly after play or when the house is being dusted. A differential diagnosis pointed to a huge possibility of allergic rhinitis or common cold. Nonetheless, based on subjective assessment and physical examination, common cold was ruled out since the patient was afebrile, hence ruling out the possibility of an infection. As such, the primary diagnosis for this patient was allergic rhinitis and according to Greiner et al. (2012), allergic rhinitis or ...

Dust Bowl is an environmental catastrophe that occurred in the Southern Great Plains of U.S.A. The top soil in the great plains, literally flew away in the wind created a dust cloud in the region. The wind erosion was so intense that it almost smothered human, animal and plant life in the process. Following the incident, the land became a barren landscape and unsuitable for human inhabitation. Farmers and families were forced to leave the land and settle elsewhere as the dust made it difficult to breath. Many agricultural experts blame over cultivation and draining of soil resources as ...

A Problem Exists

Riding motorcycles without a helmet can be equated to confronting a risk head on while hoping that chances will likely save you. The best way to stay safe is by preventing the risk in the first place rather than trying to find ways of reducing the impact of the risk. The numbers of motorcycle accidents over the recent past are evidence as to why all motorcycle riders should wear their helmets at all times when riding their motorcycles. Several studies have been conducted by different companies trying to look into the issue of whether the helmets have any correlation ...

Introduction

It was a unique time in history; slavery had been abolished, Jim Crow las were in effect but the civil rights movement had not yet begun. Voices like Langston Hughes spoke out against the racial oppression. Hughes himself wrote many short stories, poems and plays in his time. One of the themes that repeats itself in the works of Hughes is the word “mulatto”. “Mulatto”, a word used to describe a person of mixed black and white heritage, elicits a negative feeling or response from most people given the prejudiced nature of the word.

Relationships between society and nature have become much more complicated in the conditions of scientific-technical progress. People received the opportunity to influence the course of natural processes, have subdued the forces of nature, began to master almost all of the available regenerative and non-renewable natural resources, but to pollute and destroy the environment. Air pollution has remained the major problem in the modern society. It is defined as the introduction by man into the environment of substances or energy liable to cause hazard to human health, harm to living resources and ecological systems. (Tiwary, Colls, & Colls, 2010) Artificial (anthropogenic) ...

Extraction Stage

Extraction of copper produces both specks of dust and gaseous wastes such as sulfur dioxide and carbon dioxide that significantly contribute to environmental pollutions, especially air pollution (“Copper Mining”). Whereas copper wire miners reduce this pollution level by trapping the generated sulfur dioxide gas for purposes of producing sulfuric acid, considerable amounts of sulfur dioxide still escape and take part in both air and water pollution. However, extraction methods that incorporate emulsion of liquid membranes and applications of microorganisms in removing copper from their underground ores have been currently established as the economical and viable ways of gathering copper. ...

George Herbert (1593-1633) adopted the Metaphysical style of poetry from Donne but in a simpler manner. His famous poem “Death” is an example of the poetry that uses rhetorical forms of writing like a paradox, hyperbole, and conceits. The poem constitutes two parts that have a contradicting view of death. The First part presents death as a fearsome being through the use of hideous expressions and imagery. The second part presents death as a friend and a passage to a better life. The last three stanzas give hope to Christians through the works of Jesus Christ. Through Christ’s ...

The heat was intense. The orange light shone on the desert, drying up the remaining puddles of water into vapour, rising into the atmosphere. A lizard crawled slowly, almost dying, parched and with a hide so leather like, one would think it was crisp fried. Slowly, I heard the intense ringing of the siren. Waaang waaaang waaang. It was time to get inside our shelters. The shelters were not made of concrete. Unlike the olden days, concrete was the material of choice. All buildings were once made from stone, from cement mixed with water to form hard solid blocks. ...

Occupational and Environmental Health in Carbon Nano-Tube Thread Manufacturing

Carbon nanotubes (CNT) have novel physicochemical properties accompanied by new risks and uncertainties (European Agency for Safety and Health at Work [EU-OSHA], 2009). CNT release into environment and worker exposure can occur during any stage of production, usage, transport, waste treatment or storage. Data on occupational exposure to CNT is limited, and measurement techniques are also not fully developed. Engineering controls and personal protective equipment used for aerosol pollution are recommended for CNT also. Though CNTs have a primary graphene structure, their properties are entirely different from carbon particles, for which there are established exposure limits. CNT emissions are ...

According to EPA (2016), environmental management involves the development of systems aimed at reducing environmental impacts of various activities. In the Brundtland commission report (WCED), sustainable development has been described as development aimed at meeting the current needs of the present generation. However, as the current generation focuses on meeting their own needs, their activities should not compromise the capability of future generations to also meet their own needs. Available evidence suggests that the future generation would have challenges meeting their own needs if the current generation fails to adopt sustainable practices. The sustainable development incorporates the triple line: ...

The Effects of Climate Change on Allergies and Asthma Cases

Since the discovery of global warming or climate change, scientists have been warning the public of the possible implications this phenomenon could bring. They highlight erratic and severe weather patterns, changing ecosystems and the persistence of diseases that cannot easily be treated.

Introduction

Interactions between atmospheric energy and matter and with the surface of the earth play an important role in remote sensing. There is a constant interaction between the surface of the earth, electromagnetic radiation and the atmosphere. This interaction determines the spectral areas through which remote sensing can be done (Bucholtz, 1995, 2769). Electromagnetic radiation is propagated via the earth's atmosphere at the speed of light once it has been generated. Since the earth's atmosphere is not a vacuum, it has a different impact on the wavelength, spectral distribution, speed and direction of radiation.
