Primary myelofibrosis with concurrent paroxysmal nocturnal haemoglobinuria presenting with erectile dysfunction.

Primary myelofibrosis and paroxysmal nocturnal haemoglobinuria (PNH) are uncommon clonal blood disorders that are rarely found together. We report a case of primary myelofibrosis (PMF) with concomitant subtle PNH in a 42-year-old man who presented with a 4-week history of fatigue, unexplained chest pain, and new-onset erectile dysfunction. Bone marrow biopsy showed severe fibrosis consistent with PMF. However, smooth muscle dystonia symptoms in the form of new-onset erectile dysfunction and oesophageal spasm were not fully explained by PMF but were clues for PNH, confirmed by flow cytometric assays. Routine PNH testing for patients with new-onset PMF and clinical symptoms suggestive of PNH, as well as those with refractory anaemia despite effective therapy, is crucial since these two conditions can coexist. As a result, a lack of early testing may cause a delay in diagnosis, increasing the patient's transfusion load and the facility's costs.

Mycetoma in Yemen: clinicoepidemiologic and histopathologic study.

BACKGROUND: Mycetoma is widespread in Yemen, but has not been fully documented. METHODS: A prospective study of 70 patients (53 male, 17 female; from different regions of Yemen) was performed. The clinical profile of the cases was recorded in a special protocol. The diagnosis was based on clinical features, examination of grains, roentgenographic studies, and histopathology (44 cases). RESULTS: Fifty cases were diagnosed as eumycetoma and 20 as actinomycetoma. The identification of the causative species was performed in 44 cases by histopathologic studies. Among the cases of eumycetoma, Madurella mycetomatis was recognized in 27 patients, Leptosphaeria senegalensis in two, and pale-grain fungi in two. Among the cases of actinomycetoma, Streptomyces somaliensis was seen in eight patients, Streptomyces madurae in one, and Nocardia species in four. The treatment of eumycetoma patients with ketoconazole and excision in selected cases controlled the disease activity in the majority. Most of the cases of actinomycetoma were better controlled with drug therapy alone, with a combination of penicillin and cotrimoxazole, or cotrimoxazole alone. CONCLUSIONS: Mycetoma is widespread in Yemen, with a higher incidence of eumycetoma and a maximum number of cases from the Hudaida region. A multicenter study is needed to evaluate the exact extent of disease.
