RESUMEN
Spinal cord involvement associated with severe copper deficiency has been reported in the last 8 years. Copper deficiency may produce an ataxic myelopathy. Clinical and neuroimaging findings are similar to the subacute combined degeneration seen in patients with vitamin B12 deficiency. Macrocytic, normocytic and microcytic anemia, leukopenia and, in severe cases, pancytopenia are well known hematologic manifestations. The most patients with copper deficiency myelopathy had unrecognized carency. Some authors suggested that early recognition and copper supplementation may prevent neurologic deterioration but clinical findings do not improve. We present a patient with copper deficiency, dorsal root ganglions and cervical dorsal columns involvement. Clinical status and neuroimaging improved after copper replacement therapy. Sensory neurons of dorsal root ganglia may be the most sensitive nervous pathway. In this case the early copper treatment allowed to improve neurologic lesions and to prevent further involvements.

OBJECTIVE: We describe a case of irreversible subacute sclerotic combined degeneration of the spinal cord in a Western vegan subject. METHODS: A 57-y-old man, member of a vegan cult for 13 y, developed weakness, paraplegia, hyper-reflexia, distal symmetric muscular hypotrophy, impairment of superficial sensation in the hands and feet, loss of deep sensation in the lower limbs, and neurogenic bladder and bowel. Magnetic resonance imaging of the cervical and dorsal spine disclosed abnormally increased signal intensity on T(2)-weighted sections in the posterior and lateral columns. Subacute sclerotic combined degeneration of the spinal cord was diagnosed and treatment with cobalamin was started. RESULTS: Despite rehabilitative treatment, the patient developed spastic hypertonia with mild improvement of paresthesias. Six months later, vitamin B12 plasma levels and hematological analysis were normal. One year later, spastic paraplegia was still present and the patient was unable to walk despite improvement on magnetic resonance imaging. CONCLUSION: Irreversible subacute sclerotic combined degeneration of the spinal cord is a rare but possible effect of a strict vegetarian diet.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG), initially described by Gagner's group as the first stage of the laparoscopic duodenal switch in super-obese patients, is now gaining wide diffusion among bariatric surgeons as a new restrictive operation. METHODS: From January 2005 to January 2006, 8 obese patients with BMI 37-74 kg/m(2) underwent LSG for conversion from a prior complicated or failed laparoscopic adjustable gastric banding (LAGB). Three patients had severe symptomatic esophageal dilation, while 5 patients had unsuccessful weight loss with poor "band compliance". After de-banding, LSG was calibrated upon a 34-Fr gastric bougie, and blue and green linear staplers were used. The staple-line was buttressed by placing a sero-serosal running suture in all but one patient, and methylene blue dye was used to test for leaks. All the patients underwent upper GI series with water-soluble contrast medium 2 days after the surgery. RESULTS: The average operating-time for LSG was 90 minutes (range 60-120 min). The average hospital stay was 4 days (range 3-7). There were no perioperative complications, no conversion, and no mortality. No intraoperative or postoperative blood transfusions were required. CONCLUSIONS: LSG proved to be feasible and safe after LAGB. Longer follow-up and larger series are needed to assess weight loss results.
