摘要：Background: Traumatic Injection Neuropathy (TIN) can occur because of unsafe intramuscular injection practices. TIN presents as acute peripheral neuropathy with flaccid paralysis of the injected limb within 24 hours after injection and is associated with pain and hypothermia in the affected limbs. This complication is of particular concern in countries with high rates of unnecessary injections. Objective: The main objectives were to determine the incidence of Traumatic Injection Neuropathy (TIN) and hospital outcome of patients within 60 days of admission. Material & Methods: The records of all patients followed with flaccid paralysis through the WHO program for Acute Flaccid Paralysis (AFP), concerning eradication of poliomyelitis with the differential diagnosis including TIN in governorates in Yemen. From 1 January 2010 to 31 December 2015 were reviewed. Those patients suspected to be TIN were examined by a neurologist and pediatric consultant to confirm the diagnosis. At the time of admission, specific form was designed to record demographic characteristics, clinical finding and presentation of paralysis. All patients follow up for 60 days. Results: During the study period, 788 patients were diagnosed as TIN. Of these 529 (67.1%) were males and 295 (32.9%) were females. The age of the patients was ranged (between 1 to 15 years), and most of them 555 (70.4%) were young children of ≤5 years old and 233 (29.5%) cases were 5-15 years old. The overall incidence was 28/100,000 population. The outcome of patients showed that 354 (44.9%) had residual paralysis. 429 (54.4%) TIN patients improved, and 3 (0.4%) were lost, and 2 (0.3%) patients died within 60 days of follow-up. Conclusion: This study confirms that traumatic injection neuritis is the second most common cause of Acute Flaccid Paralysis in Yemen after Guillain-Barré Syndrome with high morbidity in children.
