Vitamin B12 deficiency in exclusively breastfed infants is an important problem in developing countries. Vitamin B12 deficiency is associated with a wide spectrum of clinical manifestations. Few cases of vitamin B12 deficiency have been reported as the cause of infantile spasms. We report the case of a 6-month-old boy diagnosed with infantile spasms associated with vitamin B12 deficiency caused by nutritional inadequacy in the mother. He was observed to have head nods and flexor limbs spasms which appeared in clusters. Psychomotor development was normal. The serum vitamin B12 level was low and results of electroencephalography (EEG) indicated modified hypsarrhythmia. His symptoms resolved after synthetic adrenocorticotropic hormone (ACTH) and vitamin B12 treatment. The EEG was completely normal after the first month and sixth month of treatment. In addition to ACTH and vitamin B12 treatment, following antiepileptic drug treatment was not initiated. During 21 months’ follow up he is seizure-free and his neurological development is age-appropriate. This case of a 6 month-old infant with infantile spasms due to vitamin B12 deficiency seems to be a striking because of only with vitamin B12 and ACTH treatment the patient became seizure-free. Vitamin B12 deficiency may be a treatable cause of infantile spasms and should be considered in the associated cause of infantile spasms especially if nutritional inadequacy in the mother.

95 patients in Sorokdo national hospital injected 1-5mg Hydroxocobalamin (5mg/2ml/1ample) in 5-7 days/week, duration 6.4 months, average age 71.6 years old. Effects are 1) softening of hand movement(22/95), early effect, 2) improving of motor function (8/95) 3) sensory function(8/95) 4) sweating (3/95) 5) neuropathic pain and headache(neuralgia-like) (7/95) 6) jaw and hand tremor (7/95) 7) no response (41/95) 8) side effect (1/95) Leprosy is demyelinating peripheral neuropathy, Vitamin B12 effects on myelin, but unkown it's mechnism. Vitamin B12 improve nerve function impairments in leprosy, especially neuropathic pain and tremor, which lead to deformities and disabilities.

Background: Vitamin B12 is one of the common drugs used by physicians to treat peripheral neuropathy (PN), although many patients have a good response, however, overdose and toxicity aggravate the condition and worsen the patient’s symptoms. The purpose of this paper is to highlight association between Vitamin B12 toxicity and deterioration of PN symptoms. Case Summary: An elder Sudanese man with acute onset of sensory PN, the patient’s symptoms started by tingling sensations and paresthesia affecting both hands and feet. After patient received cobalamin (vitamin B 12) prescribed by his doctor, the patient symptoms were markedly aggravated and his condition worsened to extend that impaired the normal patient ordinary work. No symptoms related to motor system. Other possible etiologies were studied and excluded. Investigations of his condition revealed blood level of B12 was 1900 pg/mL, the patient condition improved dramatically with discontinuation of the drug. Conclusion Cobalamin toxicity aggravate sensory PN symptoms. Clinicians are advised to adjust the dose and check Cobalamin level before and during treatment to avoid its toxicity.

PURPOSE: Vitamin B12 (VB12) deficiency is an inevitable sequela of a total gastrectom, which results in general symptoms, including easy fatigue, and hematological, neurological, and gastrointestinal complications. Especially in cases of neurological injury, it may be irreVersible if the timely treatment is delayed. Therefore the early diagnosis and treatment is essential. However, no guidelines exist for the incidence or treatments. METHODS: We investigated the symptoms and serum VB12 concentrations of 296 patients who underwent a total gastrectomy for a gastric malignancy. We defined 200~300 pg/ml as the mild decrease group, under 200 pg/ml as the severe decrease group, and over 300 pg/ml as the normal limit. RESULTS: The cumulative incidence of VB12 deficiency were 5.1, 11.2, 29.9, 44.7, 64.5% at 6 month, 1, 2 and 3 years, and at 4 or more years, respectively. The 90% of patients reported at least 1 symptom. The group under 200 pg/ml was supplemented at 1 month intervals; 10 of the 16 patients (63%) had their VB12 elevated to above 300 pg/ml. The group between 200~300 pg/ml was supplemented at 1 or 3 month intervals; 21 out of 23 (91%), and 12 out of 15 patients (80%) had their B12 elevated to above 300 pg/ml at the 1 and 3 month intervals, respectively, but with no statistical significance. CONCLUSION: The group with a V12 under 200 pg/ml should be supplemented 6 times, at 1 month intervals, regardless of the symptom presentation, and when the rechecked serum VB12 level has been increased above 300 pg/ml, it should be supplemented at 3 month intervals. In the group with a VB12 between 200 and 300 pg/ml, the VB12 should be supplemented at 3 month intervals if the symptom is present, and the asymptomatic group should be observed.
