Hypo and hyperglycemia among tramadol overdose patients in Loghman Hakim Hospital, Tehran, Iran

Tramadol is a synthetic and centrally active analgesic. Hypoglycemia as another possible major side effect among abusers has not been known well. Our objective is evaluation of the Blood Glucose Level [BGL] among tramadol-overdosed patients. This prospective cross-sectional study was performed from Feb to June 2013; BGL was measured at the time of admission, 8 and 12 hours later. All patients with hypoglycemia received infusion of 0.5-1gr/kg of hypertonic dextrose and their BGL was checked every hour until normal BGL. Patients' demographic, clinical and paraclinical data were collected. Totally, 128 patients with a mean [SD] age of 24.5 [6.9] years were recruited; 127 [99.2%] were male. Seizure occurred in 59.4% cases. Mean +/- SD admission BGL was 94.88 +/- 21.5mg/dL. Fourteen patients experienced hypoglycemia within 12 hours period. Hyperglycemia was experienced in 8 patients [6.25%] on admission day. There was no significant relation between the dose of tramadol and BGL. In conclusion, hypoglycemia must be considered asan important side effect of tramadol-overdose. It is suggested that serial BGL monitoring in cases of Tramadol-overdose should be done for early recognition of hypoglycemia and its timely management. Also hyperglycemia may be revealed

Lack of association between the C677T single nucleotide polymorphism of the MTHFR gene and glaucoma in Iranian patients

Glaucoma is a major cause of blindness worldwide. A single nucleotide polymorphism of the MTHFR gene [C677T] has been associated with susceptibility to this disease, although this is controversial in the last decade. In this study, the possible association between the MTHFR C677T polymorphism and the risk of developing primary open angle [POAG] and pseudoexfoliation glaucoma [PEXG] was investigated. For this, a prospective study consisting of 73 POAG, 85 PEXG and 90 matched controls was undertaken in an Iranian population. Genomic DNA was extracted from whole blood. Genotyping of all individuals for the MTHFR C677T polymorphism was conducted using the PCR-RFLP technique. Our findings revealed no significant association between the MTHFR C677T polymorphism in POAG and PEXG compared with controls. Consistent with several other studies, our analysis suggests that the MTHFR C677T polymorphism is unlikely to be a factor contributing to the risk of developing specific forms of glaucoma
