Abstract

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.

1. Introduction

The World Health Organization (WHO) in 1999 reported that out of the 8 - 12 billion injections administered worldwide annually, the vast majority (90% - 95%) are for therapeutic purposes, and 50 percent are unsafe, and 75 percent are unnecessary. Injection administration is seen as one of the most common healthcare procedures, and unsafe injections are associated with morbidity and mortality, especially in developing countries [1] [2] [3] .

Traumatic Injection Neuropathy (TIN) can occur because of unsafe intramuscular injection practices. TIN involving the sciatic and radial nerves 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 [4] [5] [6] .

This complication is of particular concern in countries with high rates of unnecessary injections [2] .

While some data exist regarding the medical complications of these injections, no estimate has been published regarding the disease burden caused directly by injection trauma [5] .

Affected individuals usually present with foot drop and this can result in varying degrees of motor disability depending on the timing and duration of corrective measures instituted [7] .

In Yemen, all acute flaccid paralytic conditions are reported to the Acute Flaccid Paralysis (AFP) surveillance system of the poliomyelitis eradication initiative. The AFP surveillance system has achieved or exceeded global targets for quality and sensitivity since 2000.

This study was a review of AFP surveillance data to identify the incidence of TIN in Yemen and to describe the basic epidemiology of the disease.

2. Methods and Materials

The records of retrospective patients followed with Acute Flaccid Paralysis (AFP) through the WHO program in the Ministry of health of Yemen. Approval was obtained through a local committee of AFP program prior to the commencement of the study, and that informed patient consent was received from all study participants. We searched the case records of AFP surveillance data collected between 1 January 2010 and 31 December 2015 to identify potential cases of Traumatic Injection Neuritis (TIN). The data collected concerning eradication of poliomyelitis with the differential diagnosis including (TIN) in Yemen. The TIN was clinically diagnosed by neurologist and pediatrics consultation. The clinical and demographic characteristics, including age, gender, preceding events, presentation of paralysis of the lower limb Left or Right at the time of examination with 60 days follow up for each case by health team workers in each governorate.

The diagnosis is confirmed on the basis of clinical presentation by examination of neurologist or pediatric consultant in each governorate. A structured questionnaire was designed which documented age of the patient, sex and its distributions concerning TIN residual cases, non-residual cases and died or lost cases in these governorates.

Epi info statistical method was used for analysis of data.

3. Results

Demographical and clinical features:

Of 788 TIN patients, there were 529 male (67.1%) and 259 female (32.9%) patients, as shown in Figure 1.

There were 555 (70.4%) patients under the age 5 years, patients ranging from 5 to 15 years 233 (29.5%), as shown in Table 1, Figure 2 and Figure 3.

Patients characteristic of paralysis with follow up after 60 days, 429 (54.4%) TIN patients non residual (improved) and 354 (44.9%) residual (not improved) all Governorates in Yemen, as shown in Figure 4.

4. Discussion

Injection-related traumatic neuropathy often results in life-long disability [6] .

As we progress towards WHO eradication of poliomyelitis, causes of Acute Flaccid Paralysis other than polio, we found Traumatic Injection Neuritis (TIN)

becoming more apparent. As we found 788 (TIN) cases, which now emerged as one of the most common cause of acute flaccid paralysis in Yemen in children under the age of 15 years after Guillain-Barré syndrome [8] .

Most of the affected patients were males (67.1%) males and (32.9%) females, with similar result found in a study in Pakistan [9] .

The predominance of males in the results is unexplained but may reflect the greater priority for health care given to boys over girls, which may be related to the culture behaviors.

Most of the cases (70.4%) were less than 5 years old and (29.5%) of cases 5 - 15 years old, which revealed the severity of this problem in children below 5 years, which can be explained due to receiving immunization at the gluteal region, and children at this age group are at high risk of infection.

In supporting to our study, a study carried in Pakistan found similar problem is particularly severe in children under the age of 1 year who suffer from a higher complication rate from injection methods, inappropriate for this age group [9] .

Other study in Nigeria found children below the age of five years constituted more than two thirds (84.7%) of the cases and males were more than females [10] .

Children are more often affected than adults because less fat pad and lack of muscle bulk relative to adults and are more prone to sciatic nerve injury [1] [11] [12] [13] .

In a review done by Mishra et al. 2010 reported 1506 sciatic nerve injuries of which 80% were affected in childhood [12] .

In our study (54.4%) TIN patients improved and (44.9%) not improved in all Governorates in Yemen. The high number of not improved patients reflects the more severity of injury in children and inappropriate management and care after the injury, which is also found in Pakistan, as the residual paralysis 60 days after the onset of paralysis and was more common in children below 1 year of age than in older children [9] .

Also the high percentage of not improved cases found in Iranian study, which concluded the high possibility of sciatic nerve injury is due to gluteal injection and its poor recovery in children [14] .

In Yemen, it is observed that many untrained, unlicensed practitioners give these injections with inappropriate and unsafe injection practices.

5. Conclusion

Traumatic injection neuritis is the second most common cause of Acute Flaccid Paralysis in Yemen after Guillain-Barré Syndrome with high morbidity in children.

6. Recommendation

1) More awareness about TIN in the medical and para-medical staff as:

・ Traumatic injection neuritis is a preventable complication of intramuscular injection.

・ Total avoidance of such injections is desirable, but if an intramuscular injection is essential, use of an appropriate administrative technique is crucial.

・ If any TIN is suspected, immediate and optimal injury management can reduce neurological sequel and maximize the likelihood of recovery.

2) Further research using electrophysiology for assuring diagnosis of TIN and to predict the prognosis by follow-up.
