ABSTRACT: There are controversial results and insufficient knowledge in the literature about the genetics of diabetes mellitus complications in the Turkish population and endothelial nitric oxide synthase (eNOS) gene polymorphisms may act as a potential modifier of diabetic vascular complications.
The objective of this study was to determine the association between eNOS G894T polymorphisms and diabetes-related diseases.
A Turkish case-control study was designed.
The study was carried out in the Ankara University Hospital.
Totally, 97 Turkish patients with diabetic foot ulcers and 102 controls were enrolled. Patients who had not received antimicrobial treatment in the preceding 6 months were included. Diabetic patients with hand and/or foot ulcers resulting from major trauma, such as road traffic accidents, were excluded.
The effect of eNOS gene polymorphisms on diabetic complications and comorbid diseases was measured.
Regarding eNOS G894T gene polymorphisms, 47.4% of the patients had GG (n = 46), 47.4% (n = 46) had GT, and 5.2% (n = 5) had TT alleles in the diabetes mellitus group, and 47.0% (n = 48), 41.2% (n = 42), and 11.8% (n = 12) had GG, GT, and TT alleles in the control group, respectively. There was no significant difference between the groups regarding the eNOS G894T gene allele ratios. Between groups with and without diabetic complications, a significant difference has only been found in the distribution of alleles in patients with comorbid atherosclerotic heart disease, whose GT-TT alleles were significantly higher than the GG alleles (p = 0.004).
G894T polymorphism of eNOS gene was not associated with foot ulcer and diabetic complications, except in the presence of atherosclerotic heart disease.

ABSTRACT: A 43-year-old female patient admitted with a 2.5-year history of lower extremity symmetrical sensorimotor polyneuropathy, hypertrichosis, sweating, diarrhea, weight loss, and hyperpigmentation. The clinical evaluation met the criteria for the diagnosis of POEMS syndrome. The patient was initially treated with prednisolone and responded well. We planned high-dose chemotherapy with autologous stem cell rescue and introduced a more immunosuppressive regimen containing cyclophosphamide and dexamethasone. We present a case differing from the other cases with her 2 g/day proteinuria and hypertrophic osteoarthropathy.

ABSTRACT: Cavernous angiomas or cavernomas are uncommon vascular malformations of the central nervous system and spinal involvement is much rarer especially in pediatric patients. We report a case of spinal intradural-intramedullary cavernous angioma in a 14-year-old male child. The cavernoma was located at the level of C6-C7 at the dorsal part of the spinal cord. The diagnosis was made with MRI and the patient underwent surgical treatment. The cavernoma was totally removed with laminotomy and microsurgical techniques. Somatosensory evoked potential monitoring was also used peroperatively. The clinical, radiological and surgical features of this rare case were presented and discussed with reference to the literature.
