Abstract
Cluster headache (CH) is a primary headache disorder with a complex genetic background. Several studies indicate a potential link between iron homeostasis and the pathophysiology of primary headaches. The HFE gene encodes for a protein involved in iron metabolism, while genetic variants in HFE have been associated with hereditary hemochromatosis (HH), an iron overload disorder. The objective of the current study was to examine the association of the more common HFE H63D variant, with the susceptibility to develop CH and diverse clinical phenotypes in a population of Southeastern European Caucasian (SEC) origin. Genomic DNA samples from 128 CH patients and 294 neurologically healthy controls were genotyped for the HFE rs1799945 (H63D) variant. H63D genotypic and allelic frequency distribution did not differ significantly between patients and controls (p > 0.05). Subgroup analysis revealed a significantly more frequent occurrence of the variant G allele in chronic compared to episodic CH patients, indicative for a possible correlation of the HFE gene with the susceptibility for disease chronification. Although homozygosity for the less prevalent H63D variant G allele was minimal in the CH cohort, the results of the present study are in accordance with previous studies in CH and migraine patients, suggesting that HFE H63D variant modifies the disease clinical characteristics. Hence, despite the absence of a per se association with CH susceptibility in the current SEC cohort, variability in HFE gene may be potentially regarded as a disease modifier genetic factor in CH.

Abstract
We present here two cases of extraskeletal Ewing's sarcoma, the first in a 50-year-old female and the second in a 25-year-old male. We discuss the clinical picture, histopathology and therapeutic management. The literature is also reviewed, with major emphasis on the treatment of this rare disease.

Abstract
The coexistence of systemic lupus erythematosus and myelofibrosis is a rare occurrence. A review of the literature available to us revealed only five other patients with this combination. We have recently encountered a patient in whom these two diseases existed concomitantly, and in this report we shall describe the clinical course of our patient and discuss it in comparison with the patients described previously.

Abstract
Two cases of nonmalignant immunoproliferative small intestinal disease (IPSID) presenting with severe malabsorption are described. The first patient had a lymphocytic infiltrate of the lamina propria and lymphoid hyperplasia of the mesenteric lymph nodes and responded to oral tetracycline. The second patient had a polyclonal plasmacytic infiltration of the lamina propria and of the mesenteric nodes and responded only to cytotoxic treatment with cyclophosphamide. These cases represent examples of non-alpha-chain disease benign IPSID.
