Information on the burden of these infections is important for improved patient outcomes. The burden of serious fungal infections in Ghana is unknown. We aimed to estimate this burden. Using local, regional, or global data and estimates of population and at-risk groups, deterministic modelling was employed to estimate national incidence or prevalence. Our study revealed that about 4% of Ghanaians suffer from serious fungal infections yearly, with over 35,000 affected by life-threatening invasive fungal infections. -

Monograph on Dematiaceous Fungi
Monograph On Dematiaceous fungi A guide for description of dematiaceous fungi fungi of medical importance, diseases caused by them, diagnosis and treatment By Mohamed Refai and Heidy Abo El-Yazid Department of Microbiology, Faculty of Veterinary Medicine, Cairo University 2014 1 Preface The first time I saw cultures of dematiaceous fungi was in the laboratory of Prof. Seeliger in Bonn, 1962, when I attended a practical course on moulds for one week. Then I handled myself several cultures of black fungi, as contaminants in Mycology Laboratory of Prof. Rieth, 1963-1964, in Hamburg. When I visited Prof. DE Varies in Baarn, 1963. I was fascinated by the tremendous number of moulds in the Centraalbureau voor Schimmelcultures, Baarn, Netherlands. On the other hand, I was proud, that El-Sheikh Mahgoub, a Colleague from Sundan, wrote an internationally well-known book on mycetoma. I have never seen cases of dematiaceous fungal infections in Egypt, therefore, I was very happy, when I saw the collection of mycetoma cases reported in Egypt by the eminent Egyptian Mycologist, Prof. Dr Mohamed Taha, Zagazig University. To all these prominent mycologists I dedicate this monograph. Prof. Dr. Mohamed Refai, 1.5.2014 Heinz Seeliger Heinz Rieth Gerard de Vries, El-Sheikh Mahgoub Mohamed Taha 2 Contents 1.

Gastrointestinal Basidiobolomycosis, a Rare and Under-Diagnosed Fungal Infection in Immunocompetent Hosts: a Review Article
IJMS Vol 40, No 2, March 2015 Review Article Gastrointestinal Basidiobolomycosis, a Rare and Under-diagnosed Fungal Infection in Immunocompetent Hosts: A Review Article Bita Geramizadeh1,2, MD; Mina Abstract 2 2 Heidari , MD; Golsa Shekarkhar , MD Gastrointestinal Basidiobolomycosis (GIB) is an unusual, rare, but emerging fungal infection in the stomach, small intestine, colon, and liver. It has been rarely reported in the English literature and most of the reported cases have been from US, Saudi Arabia, Kuwait, and Iran. In the last five years, 17 cases have been reported from one or two provinces in Iran, and it seems that it has been undiagnosed or probably unnoticed in other parts of the country. This article has Continuous In this review, we explored the English literature from 1964 Medical Education (CME) through 2013 via PubMed, Google, and Google scholar using the credit for Iranian physicians following search keywords: and paramedics. They may 1) Basidiobolomycosis earn CME credit by reading 2) Basidiobolus ranarum this article and answering the 3) Gastrointestinal Basidiobolomycosis questions on page 190. In this review, we attempted to collect all clinical, pathological, and radiological findings of the presenting patients; complemented with previous experiences regarding the treatment and prognosis of the GIB. Since 1964, only 71 cases have been reported, which will be fully described in terms of clinical presentations, methods of diagnosis and treatment as well as prognosis and follow up.

Case Report of Subcutaneous Entomophthoromycosis with Retroperitoneal Invasion
RELATO DE CASO/CASE REPORT Revista da Sociedade Brasileira de Medicina Tropical 38(4):348-350, jul-ago, 2005 Case report of subcutaneous entomophthoromycosis with retroperitoneal invasion Relato de caso de entomoftoromicose subcutânea com invasão retroperitoneal Leonora Maciel de Souza Vianna1, 2, Marcus Vinícius Guimarães de Lacerda1 and Mário Augusto Pinto de Moraes1 ABSTRACT The authors describe a case of entomophthoromycosis in a previously healthy patient, who presented with an abscess in the right buttock. After surgical drainage it evolved into a retroperitoneal tumor. The patient improved clinically after resection of the mass and ketoconazole treatment. The histopathological analysis showed the Splendore-Hoeppli phenomenon, suggesting Basidiobolus ranarum infection, a zygomycosis generally restricted to the subcutaneous tissue, with rare gastrointestinal involvement. Key-words: Basidiobolus ranarum. Zygomycosis. Entomophthorales. Clinical features. Histopathology. Splendore-Hoeppli phenomenon. RESUMO Os autores descrevem um caso de entomoftoromicose em paciente previamente saudável, que apresentou abscesso em nádega direita, evoluindo, após drenagem cirúrgica, para tumoração retroperitoneal. Após ressecção da massa, o paciente obteve melhora clínica, em uso de cetoconazol. A análise histopatológica evidenciou fenômeno de Splendore-Hoeppli, sugerindo infecção por Basidiobolus ranarum, uma zigomicose geralmente restrita ao tecido subcutâneo, com raro comprometimento gastrintestinal. Palavras-chaves: Basidiobolus ranarum. Zigomicose.
