Nasal Rhinosporidiosis in a Nigerian Child

Rhinosporidiosis is a rare chronic granulomatous infectious disease caused by Rhinosporidium seeberi and it usually presents as a granulose growth, most often in the nasal cavity or the area around the eye. This disease can be transmitted by direct contact with spores through dust, infected clothing and swimming in stagnant water. It is mainly endemic in India, Srilanka, Bangladesh; and sporadic cases have been reported from United States of America, Italy Brazil, Argentina and Africa.

Based on some literature research, it can be found that few cases of nasal rhinosporidiosis have been reported in Nigeria. So in this paper, the authors reported a rare case of nasal rhinosporidiosis in a 13-year-old male patient from Sokoto, North Western Nigeria and aimed to caution otorhinolaryngologists to have a high index of suspicion of this emerging disease entity in the management of patient with nasal mass. The patient was presented at the ENT clinic of Usmanu Danfodiyo University Teaching Hospital with 15-month history of intermittent epistaxis and left nasal mass noticed one month before presenting. After entering in the hospital, he was examined clinically and there was a strawberry like, fleshy polypoidal mass arising from the septum on probing and filling the left nasal cavity with associated clear mucoid rhinorrhea. Hematologic investigations showed the patient’s packed cell volume to be 24% while the biochemical results were within normal limits. He was also negative to HIV I and II screening. Plain radiographs of the paranasal sinuses demonstrated a soft tissue shadow in the left nasal cavity but no bony or sinus involvement. Histopathology of the specimen showed numerous sporangium containing spores pathognomonic of rhinosporidiosis. Finally, the disease was confirmed. Then the authors made a discussion on this disease. 

In conclusion, rhinospridiosis is an unusual cause of nasal masses in our region and is probably a fungal disease. To the best of our knowledge, this is the first reported case in this region. This lesion largely mimics ordinary nasal polyp; therefore, it is an important possible differential diagnosis to be considered in our region when evaluating patients with nasal masses.

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Electron Spin and Proton Spin in the Hydrogen and Hydrogen-Like Atomic Systems

Read full paper at: http://www.scirp.org/journal/PaperInformation.aspx?PaperID=52202#.VIj7tMnQrzE Author(s) Stanisław Olszewski * Affiliation(s) Institute of Physical Chemistry, Polish Academy of Sciences, Warsaw, Poland . ABSTRACT The mechanical angular momentum and magnetic moment of the electron and proton spin have been calculated semiclassically with the aid of the uncertainty principle for energy and time. The spin effects of both kinds of the elementary particles can be expressed in terms of similar formulae. The quantization of the spin motion has been done on the basis of the old quantum theory. It gives a quantum number n = 1/2 as the index of the spin state acceptable for both the electron and proton ...
