New surgical technique for non-missile trauma hemostasis as a result of sewing needle.

Traumas are the most important cause of mortality in the pediatric population. Bleeding is an important complication, especially in traumatic brain injuries with coagulation problem addition. Low-velocity penetrating brain injuries may be caused by sewing needles, nails, and knives. There are few studies in the literature for this injury type. This study presented a surgical technique and treatment to increase hemostasis in a 2-year-old patient after a sewing needle injury.

Non-missile penetrating brain injury-surgical techniques for removing a long penetrating foreign body: a case report.

PURPOSE: Penetrating brain injury (PBI), a relatively uncommon injury, is associated with remarkable secondary complications such as vascular injury, intracranial haemorrhage, infection, and mortality. Non-missile PBI (NMPBI) due to sharp or blunt objects is usually treated surgically by removing the penetrating object, evacuating the associated haemorrhage, identifying possible bleeders along with haemostasis, and performing debridement. Various approaches are used for different scenarios of non-missile PBI according to the object's characteristics, penetrating site, depth, associated intracerebral haemorrhage (ICH), and presence of vascular injury along the penetrating tract. NMPBI cases are rarely reported among civilians. We herein describe a patient who was successfully treated for NMPBI, as well as frontal ICH, by simultaneously removing the heavy, metallic penetrating foreign body. METHODS: We performed corticotomy through a shorter tract instead of a deep penetrating trajectory, which minimizes the extent of damage to the brain and enables immediate management of vascular injury under direct vision while removing the foreign body, and intraoperative sonography, which provides real-time information of the penetrating object and the surrounding brain structure. We did not perform computed tomography angiography and digital subtraction angiography (DSA) because the stab location was at the frontal region, with low risk of vascular injury. Moreover, DSA is time-consuming, which may delay decompressive surgery. RESULTS: The patient was successfully treated through an alternative approach removing the long, heavy, metallic penetrating foreign body and eliminating the accompanying frontal ICH simultaneously. Focal brain abscess developed 8 days after the injury and resolved completely after antibiotics treatment. Dysphasia gradually improved but right distal limbs weakness with spasticity is still present. CONCLUSIONS: Our findings suggest prompt diagnosis by preoperative imaging, screening of vascular injury, decompression with debridement, and antibiotics treatment are important. The alternative surgical approach we proposed is exceptional and should be considered while treating patients with deep NMPBI.

SURGICAL MANAGEMENT OF A PENETRATING BRAIN WOUND AND ASSOCIATED PERFORATING OCULAR INJURY CAUSED BY A LOW-VELOCITY SHARP METALLIC OBJECT: A CASE REPORT AND LITERATURE REVIEW.

Penetrating traumatic brain injury accompanied by perforating ocular injury caused by low-velocity foreign bodies is a life-threatening condition, a surgical emergency and a major challenge in surgical practice, representing a severe subtype of non-missile traumatic brain injury, which is a relatively rare pathology among civilians. Optimal management of such an injury remains controversial, requiring full understanding of its pathophysiology and a multidisciplinary expert approach. Herein, we report a case of penetrating brain and associated perforating eye injury and discuss relevant literature providing further insight into this demanding complex multi-organ injury. We present a case of 39-year-old male patient with transorbital penetrating brain and perforating ocular injury undergoing emergency surgery to remove a retained sharp metallic object from the left parietal lobe. Following appropriate and urgent diagnostics, a decompressive left-sided fronto-temporo-parietal craniectomy was immediately performed. A retained sharp metallic object (a slice of a round saw) was successfully removed, while primary left globe repair and palpebral and fornix reconstruction were performed afterwards by an ophthalmologist. A prophylactic administration of broad-spectrum antibiotics was applied to prevent infectious complications. Early postoperative recovery was uneventful. The patient was discharged on day 45 post-injury having moderate right-sided motor weakness, ipsilateral facial nerve central palsy, and light motoric dysphasia. The vision to his left eye was completely and permanently lost. In conclusion, management of non-missile transorbital penetrating brain injury can be satisfactory when proper clinical and radiologic evaluation, and amply, less radical surgical approach is performed early. A multidisciplinary routine is a prerequisite in achieving a favorable management outcome.

The role of tertiary neurosurgical intervention in non-missile penetrating injuries of the spine.

PURPOSE: The objective of the study was to determine whether all patients with spinal non-missile penetrating injuries (NMPIs) need to be managed at a tertiary neurosurgical centre. METHODS: A retrospective analysis of clinical, demographic, and imaging records was performed on all NMPI patients referred to the Department of Neurosurgery at Tygerberg Academic Hospital in Cape Town, South Africa, between 1 January 2016 and 31 December 2019. RESULTS: Ninety-six patients were identified (94 males and 2 females) with 35 cervical, 60 thoracic, and 1 lumbar spinal stab. Eighty-six had an incomplete spinal cord injury. Six patients presented with cerebrospinal fluid (CSF) leak, all of which resolved spontaneously. MRI was performed in nine patients. Six patients had retained blades, of which 5 were removed in the emergency room (ER). Surgery was performed in two patients (cervical intramedullary abscess and a retained blade). Two patients developed meningitis, and one an intramedullary abscess. Twenty-two patients had associated injuries (pneumothorax, bowel injury). The average length of stay was 17 days, with 81% being unchanged neurologically. The average time from discharge to leaving the hospital was 11 days. CONCLUSION: Early management of NMPI should include prophylactic antibiotics and wound debridement and X-ray imaging to exclude retained blades. Bowel and lung injury must be managed accordingly. Tertiary neurosurgical referral is not routinely necessary and is only warranted for deteriorating neurology, retained blades not removable in the ER, and respiratory failure secondary to spinal cord injury. Complications include meningitis and persistent CSF leak, which should be referred timeously.

Management of non-missile penetrating spinal injury.

Review of the literature with case illustration. Non-missile penetrating spinal injury (NPSI) represents a small subset of spinal cord injuries at tertiary trauma centers and is comprised mostly of knife violence. Strict guidelines for the management of penetrating spinal cord injury remain elusive given the variability of mechanisms, rarity of clinical experience, and paucity of prospective studies. A review of the literature was conducted by search of the National Library of Medicine (PubMed) in the English language through June of 2018. Additional articles were culled from the reference lists of the included series. Eleven case series totaling 1007 patients, along with 21 case reports, were identified. In summary, magnetic resonance imaging (MRI) may be beneficial in assessing incomplete or progressive spinal injuries and can be considered with retained foreign bodies in select cases. Forty-eight hours of antibiotic prophylaxis is likely sufficient to prevent infection. Puncture wounds should be debrided, washed, and closed. Retained foreign bodies should be removed in the operating room and often require laminectomy. Early intervention is preferred. Non-missile penetrating spinal injury has a higher likelihood of neurologic recovery as compared to other traumatic spinal injuries.

Surgical management and outcomes of non-missile open head injury: Report of 44 cases from a single trauma centre.

OBJECTIVE: To retrospectively analyse the surgical management and outcomes of non-missile open head injuries (NMOHI). METHODS: Forty-four patients who suffered from NMOHI were included. The Glasgow outcome score (GOS), computed tomography (CT), aetiology and outcomes and complications at discharge and during a 6-month follow-up were analysed. All patients underwent debridement. Intracranial haematoma evacuation, decompressive craniectomy (DC) or replacement were performed. RESULTS: Motor vehicle accident and struck by/against were the most common causes (43.2% each). At admission, 33 patients had Glasgow coma scores (GCS) > 8 and 27 of them had a GCS score of > 13. Mean follow-up was 8.7 ± 4.3 months. All patients underwent debridement, 20 underwent bone fracture replacement and 27 underwent haematoma evacuation; 11 patients underwent haematoma evacuation and DC and one had bilateral DC. Twenty-seven patients showed good recovery; 11 patients had moderate disability; three patients had severe disability; and three patients died. After 6 months, 32 patients had good recovery and the morbidity of severe disability had decreased to 13.6%. Thirteen patients developed intracranial infection. Post-traumatic epilepsy and hydrocephalus was detected in three patients. Cerebrospinal fluid fistula was found in five patients. Only one patient developed a brain abscess after 6 months. CONCLUSIONS: NMOHI yielded satisfactory recovery and achieved good outcomes.

Stephanion to cranial base penetrating stab wound with outstanding recovery: A case report.

Background: Mortality due to head trauma is common in developed countries in all age groups. Nonmissile penetrating skull base injuries (PSBIs) due to foreign bodies are quite rare, accounting for about 0.4%. PSBI carries that a poor prognosis brainstem involvement usually is often fatal. We are reporting the first case of PSBI with a foreign body insertion site through the stephanion with a remarkable outcome. Case Description: The 38-year-old male patient was referred with a penetrating stab wound to the head through the stephanion caused by a knife after a conflict in the street. He had no focal neurological deficit or cerebrospinal fluid leak, and Glasgow coma scale (GCS) was 15/15 on admission. A preoperative computed tomography scan showed the path of the stab beginning at the stephanion, which is the point where the coronal suture crosses the superior temporal line, heading toward the cranial base. Postoperatively, GCS was 15/15 without any deficit apart from the left wrist drop, possibly due to a left arm stab. Conclusion: Careful investigations and diagnoses must be made to ensure convenient knowledge of the case due to the variety of injury mechanisms, foreign body characteristics, and individual patients' characteristics. Reported cases of PSBIs in adults have not reported a stephanion skull base injury. Although brain stem involvement is usually fatal, our patient had a remarkable outcome.

Excellent recovery after nonmissile penetrating traumatic brain injury in a child: A case report.

Background: Nonmissile penetrating traumatic brain injuries (pTBIs) are low-velocity injuries which can be caused by a variety of inflicting tools and represent a rare entity in children. Poor outcome has been attributed with an initial admission Glasgow Coma Scale (GCS) of <5, asymmetrical pupil size, and specific initial computed tomography scan findings including brainstem injury. Case Description: We report a case of an 11-year-old boy who presented to our ER with a GCS of 6 after being assaulted on his head by a 30 cm length metallic tent hook penetrating his forehead reaching down to the central skull base zone. Conclusion: We demonstrated that following standard recommendations in the management of pTBI which include applying the advanced trauma life support protocol in ER, acquiring the needed preoperative neuroimaging studies, avoiding moving the penetrating object till patient shifted to OR, and finally performing a planned stepwise surgical intervention through craniotomy may yield an excellent functional recovery, especially in children despite an otherwise grave initial presentation and apparently profound brain injury.

Day 14 intervention for penetrating brain injury with a good Glasgow Coma Scale score: A case report.

Penetrating brain injury is a rare pathology generally requiring emergency surgical intervention. We discuss a case of penetrating brain injury by the umbrella in which surgical intervention was performed 14 days after the injury, and obtained good clinical results.

Nonmissile penetrating spinal injuries: Mechanisms, expectations, and management.

BACKGROUND: Nonmissile penetrating spinal injury (NMPSI) is an uncommon form of traumatic injury to the spine. Here, we present a comprehensive and contemporary literature review that provides insight into NMPSI-type injuries, their mechanisms, clinical practice, management, and expectations. METHODS: An extensive review of the published literature was conducted in PubMed, OVID Medline, and EMBASE journals for studies of nonmissile penetrating spine injuries. Terms for search included NMPSI and nonmissile penetrating spinal cord injury. No date restrictions were used. RESULTS: The search yielded only 17 related articles. Cross-checking of articles was conducted to exclude duplicate articles. The 17 articles were screened for their full text and English language availability. We finalized those articles pertaining to the topic. CONCLUSION: The mechanism of injury in NMPSI occurs in two different stages. Immediate injury is caused by direct damage to the neurological structures. The delayed injury response is caused by damage to the spinal vasculature and activated immune response pathways. Computed tomography (CT) angiograms or formal diagnostic angiograms are indicated to identify vascular injury or development of pseudoaneurysm and can be performed both preoperatively and postoperatively. Surgically, decompressive procedures include laminectomies and hemilaminectomies. Dural exploration may be indicated if a cerebrospinal fluid leak with fistula develops from dural puncture. Further research and technologies are being developed to provide patients who have suffered NMPSI with more resources for a better quality of life.

Transorbital nonmissile penetrating brain injury: Report of two cases.

BACKGROUND: Penetrating brain injury (PBI) is an uncommon emergency in neurosurgery, and transorbital PBI is a rare type of PBI. Reasonable surgical planning and careful postoperative management can improve the prognosis of patients. CASE SUMMARY: The first case is a 68-year-old male patient who was admitted to the hospital because a branch punctured his brain through the orbit for approximately 9 h after he unexpectedly fell while walking. After admission, the patient underwent emergency surgical treatment and postoperative anti-infection treatment. The patient was able to follow instructions at a 4-mo follow-up review. The other case is a 46-year-old male patient who was admitted to the hospital due to an intraorbital foreign body caused by a car accident, after which the patient was unconscious for approximately 6 h. After admission, the patient underwent emergency surgical treatment and postoperative anti-infection treatment. The patient could correctly answer questions at a 3-mo follow-up review. CONCLUSION: Transorbital PBI is a rare and acute disease. Early diagnosis, surgical intervention, and application of intravenous antibiotics can improve the prognosis and quality of life of patients.

Multidisciplinary Management of Low-velocity Nonmissile Penetrating Head Injuries.

Introduction Penetrating head injuries (PHIs) can have diverse presentations and mechanisms; therefore, treatment methods have not been clearly outlined. Vascular injury is common and foreign body removal is often required. We present three cases to illustrate low-velocity nonmissile penetrating head injuries (NPHIs) and discuss a multidisciplinary approach. Methods We present a case series from our institution that illustrates the importance of multidisciplinary treatment of these injuries. All injuries are low- velocity NPHIs with separate mechanisms and anatomical locations. Results Multidisciplinary management involving neurosurgery, otolaryngology, and neuroendovascular surgery is represented in our case series with all patients having good clinical outcomes. Our first case is a 34-year-old male who presented neurologically intact after a stabbing in the left temporal region with concerns for external carotid artery injury and maxillary sinus injury. Our second case is a 37-year-old male who presented with a self-inflicted nail gun injury that penetrated the right temporal bone, right temporal lobe, bilateral sphenoid sinus, and left petrous carotid canal with concerns of petrous internal carotid injury. Our third case is a 31-year-old male who presented after an accidental nail gun injury that penetrated through the oral cavity, hard palate, and left sphenoid sinus and ending in the left cavernous sinus with concerns of cavernous internal carotid injury. Conclusion  Careful consideration must be taken when evaluating low-velocity NPHIs. Particular attention must be given when an associated vascular injury is suspected. Our case series highlights the importance of a multidisciplinary approach in achieving good clinical outcomes in PHIs.

Complications, outcomes, and management strategies of non-missile penetrating head injuries.

OBJECTIVE: While high-velocity missile injury (gunshot) is associated with kinetic and thermal injuries, non-missile penetrating head injury (NMPHI) results in primary damage along the tract of the piercing object that can be associated with significant secondary complications. Despite the unique physical properties of NMPHI, factors associated with complications, expected outcomes, and optimal management have not been defined. In this study, the authors attempted to define those factors. METHODS: Consecutive adult patients with NMPHI who presented to Tygerberg Academic Hospital (Cape Town, South Africa) in the period from August 1, 2011, through July 31, 2018, were enrolled in a prospective study using a defined treatment algorithm. Clinical, imaging, and laboratory data were analyzed. RESULTS: One hundred ninety-two patients (185 males [96%], 7 females [4%]) with 192 NMPHIs were included in this analysis. The mean age at injury was 26.2 ± 1.1 years (range 18-58 years). Thirty-four patients (18%) presented with the weapon in situ. Seventy-one patients (37%) presented with a Glasgow Coma Scale (GCS) score of 15. Weapons included a knife (156 patients [81%]), screwdriver (18 [9%]), nail gun (1 [0.5%]), garden fork (1 [0.5%]), barbeque fork (1 [0.5%]), and unknown (15 [8%]). The most common wound locations were temporal (74 [39%]), frontal (65 [34%]), and parietal (30 [16%]). The most common secondary complications were vascular injury (37 patients [19%]) and infection (27 patients [14%]). Vascular injury was significantly associated with imaging evidence of deep subarachnoid hemorrhage and an injury tract crossing vascular territory (p ≤ 0.05). Infection was associated with delayed referral (> 24 hours), lack of prophylactic antibiotic administration, and weapon in situ (p ≤ 0.05). A poorer outcome was associated with a stab depth > 50 mm, a weapon removed by the assailant, vascular injury, and eloquent brain involvement (p ≤ 0.05). Nineteen patients (10%) died from their injuries. The Glasgow Outcome Scale (GOS) score was linearly related to the admission GCS score (p < 0.001). One hundred forty patients (73%) had a GOS score of 4 or better at discharge. CONCLUSIONS: The most common NMPHI secondary complications are vascular injury and infection, which are associated with specific NMPHI imaging and clinical features. Identifying these features and using a systematic management paradigm can effectively treat the primary injury, as well as diagnose and manage NMPHI-related complications, leading to a good outcome in the majority of patients.

Glass Fragment Injury to the Craniocervical Junction with Interatlantooccipital Penetration to the Subarachnoid Space: Not-To-Be-Missed Important Aspects of Craniocervical Trauma Even in the Middle of the COVID-19 Pandemic: Case Report and Review of Literature.

BACKGROUND: Nonmissile penetrating injuries to the craniocervical junction caused by a glass fragment are rare, and a standard management strategy has not been established. CASE DESCRIPTION: A 75-year-old Japanese man was brought into our emergency department after receiving a left retroauricular stab wound by broken glass fragments. After spinal immobilization, a computed tomography (CT) scan revealed glass fragments penetrating at the right craniocervical junction to the interatlantooccipital subarachnoid space. CT angiography showed that both vertebral arteries were not injured. Magnetic resonance imaging demonstrated that the glass fragments did not penetrate the cervical cord or medulla oblongata. These glass fragments were removed via a midline incision from the external occipital protuberance to the C7 and with laminectomy without suboccipital craniectomy. Five of the glass fragments were found and removed in total. The dural defect was patched with a free fascia autograft. His postoperative course was uneventful. Postoperative CT angiography showed that both vertebral arteries were intact and the glass fragments had been removed completely. CONCLUSIONS: CT graphical diagnosis is useful for the management of penetrating craniocervical junction trauma, and it should be considered in the evaluation of patients who have suffered craniocervical penetrating injury even in the absence of major wounds or bleeding. Spinal immobilization of patients with craniocervical penetrating injuries is crucial to avoid not only secondary neurologic damage but also secondary critical vascular damage. Incomplete or inadequate assessment of craniocervical stab wounds results in unexpected hazards that are preventable.

Traumatic Nonmissile Penetrating Transnasal Anterior Skull Base Fracture and Brain Injury with Cerebrospinal Fluid Leak: Intraoperative Leak Detection and an Effective Reconstruction Procedure for a Localized Skull Base Defect Especially After Coronavirus Disease 2019 Outbreak.

BACKGROUND: Cerebrospinal fluid (CSF) leakage after penetrating skull base injury is relatively rare compared with close head injuries involving skull base fractures. CASE DESCRIPTION: We report the case of a 65-year-old man who had presented with epistaxis and serous rhinorrhea. When he had fallen to the ground near his bee boxes, a garden pole had poked into his right nostril. He had instantly removed the pole from his nostril himself. However, immediately after removal of the pole, he had developed nasal bleeding and serous rhinorrhea. He then drove to our emergency room. Computed tomography showed pneumocephalus with a minor cerebral contusion in the left frontal lobe and a penetrating injury in the left anterior skull base. His CSF leakage had not resolve spontaneously within 1 week after the injury with strict bed rest. We repaired the CSF leakage using a fat (adipose tissue)-on-fascia autograft plug and caulked the defect in the anterior skull base with the fat-on-fascia graft (FFG) plug through the left nostril with endoscopic guidance. The CSF rhinorrhea was successfully controlled. Intranasal local application of fluorescein aided in the detection of the direction of flow of the CSF leakage. CONCLUSIONS: Endonasal endoscopic caulking of a skull base defect using an FFG plug can be useful to treat CSF leakage due to the localized skull base defect, especially in the coronavirus disease 2019 pandemic. It is simple, inexpensive, and timesaving. It requires no special skills nor sophisticated instruments that can cause aerosolization, reducing the risk of infection during the surgery.

Occult Transorbital Intracranial Injury by Windshield Wiper Handle: Case Report and Review of Literature.

BACKGROUND: We present the case of a 51-year-old male with an occult transorbital intracranial injury after a car accident. The identified foreign object was a windshield wiper handle. To our knowledge, this is the first case reported. CASE DESCRIPTION: Multidisciplinary treatment with maxillofacial and otorhinolaryngology departments was planned. A bifrontal craniotomy with removal of the foreign object and posterior orbital reconstruction were performed. A review of the literature was done, in order to highlight certain general principles in decision making despite the variability in case presentation. CONCLUSIONS: Occult TII is a rare subtype of penetrating brain injury. Diagnosis requires high suspicion as it can be missed during physical examination. Computed tomography (CT) scan, CT angiogram, and magnetic resonance imaging should be performed in order to design the optimal treatment for each patient. Magnetic resonance imaging should be avoided when metallic density on CT is observed. The use of a broad-spectrum antibiotic regimen is critical.

Management of a Steel Bar Injury Penetrating the Head and Neck: A Case Report and Review of the Literature.

BACKGROUND: Nonmissile penetrating injuries to the head and neck caused by a steel bar are rare, and a standard management strategy is lacking. CASE DESCRIPTION: A 42-year-old woman sustained a steel bar injury with penetration of the head and neck. Computed tomography and three-dimensional reconstruction were performed for preoperative evaluation. Digital subtraction angiography was performed to confirm potential vascular injury. The steel bar was successfully removed through an open surgical procedure by a multidisciplinary team. CONCLUSIONS: Relevant literature regarding nonmissile penetrating injuries involving a steel bar was reviewed to propose appropriate management strategies. Comprehensive imaging evaluation and prompt surgery by a multidisciplinary team contributed to the successful removal of the steel bar.

Minimally invasive approach to non-missile penetrating spinal injury with resultant retained foreign body: A case report and review of the literature.

Non- missile penetrating spinal injury (NMPSI) is a rare entity in North America and as a result there is no clear treatment paradigm. According to the literature, NMPSI causes serious acute neurological deficits and can also lead to devastating delayed complications in cases of untreated retained foreign bodies (RFB). In this report we present an acute case of NMPSI to the thoracic spine resulting in RFB treated by operative removal using minimally invasive fluoroscopic technique. While in prior published cases of NMPSI operative intervention was accomplished through laminectomy, our case presents an alternative, less invasive approach which may results in shorter recovery time. We also review the literature on NMPSI, including reports on both acute cases and chronic presentation due to RFBs. Based on this review, we conclude that NMPSI associated with RFB should be managed with operative intervention.

Survival After a Transcranial Bihemispheric Stabbing with a Knife: Case Report and Literature Review.

Low-velocity penetrating brain injuries (PBIs), also referred to as nonmissile brain injuries, typically result from stabbings, industrial or home accidents, or suicide attempts. A great deal of literature has focused on the injury patterns and management strategies of high-velocity PBIs. However, there are substantially fewer large, contemporary studies focused solely on low-velocity PBIs. Here, we present an interesting and uncommon case of a patient who suffered a bihemispheric stab wound involving the basal ganglia. A 22-year-old man presented to the hospital with a stab wound to the left calvarium. His initial Glasgow Coma Scale (GCS) score was 13, but he rapidly declined to a six and was intubated. He was emergently taken to the operating room for craniectomy, knife removal, and external ventricular drain placement. On the first postoperative day, the patient was following commands with all extremities. He was discharged to a rehabilitation facility 13 days postinjury. One year after the injury, the patient was free of major neurologic sequelae. This report illustrates a rare case of a good functional outcome after a transcranial stabbing with multiple imaging and exam findings usually associated with poor outcomes.

Pediatric Nonmissile Penetrating Head Injury: Case Series and Literature Review.

BACKGROUND: Pediatric nonmissile penetrating head injury (NMPHI) is usually accidental attributed mainly to the softer skulls of growing children. However, it is a rare entity, and therefore no consensus exists regarding treatment to effectively prevent immediate and long-term complications. Throughout the literature, these injuries are mostly discussed in case reviews and case series in the general population. No data originating from randomized studies are available because of ethical and practical limitations. METHODS: We retrospectively studied and present 5 cases of children with NMPHI treated in the last 6 years in the Neurosurgery Department of Children's Hospital "Aghia Sofia". We performed a review of the literature in PubMed, using the key words "non-missile," "penetrating head injury," and "pediatric." We included case reports and case series involving pediatric cases since 2008 and selected older reports as well as certain literature reviews focusing on analysis of complications and treatment suggestions. We compared reported practice in various institutions with suggestions from the literature. RESULTS: In the last year, 4 literature reviews were published suggesting treatment algorithms of NMPHIs. Surgery timing and method as well as anticonvulsant and antibiotic therapy still remain debatable. The only review concentrating on pediatric populations dates back to 1994, based on patient outcome studies from the 1980s. In our review, treatment steps were similar among various institutions and resembled recently suggested algorithms, with better treatment outcomes than originally reported 30 years ago.
