BACKGROUND: Open wounds to the head with skull bone depression pose the potential for serious injuries to the brain parenchyma and an increased risk of infection. The treatment of these injuries aims to repair the breached dura as well as remove any nidus for infection. Open wounds to the head due to bullets pose special problems and have a high fatality rate. AIM: To review the presentation, management and outcome of depressed and penetrating open fractures of the skull in Port Moresby. METHOD: All cases seen from 2003 to 2005 were included. All were managed without a CT (computed tomography) scan. Their Glasgow Outcome Scale (GOS) was documented on discharge. RESULTS: There were 340 traumatic brain injury (TBI) cases over a period of 3 years between 2003 and 2005 managed by the Neurosurgery Unit of Port Moresby General Hospital. The open depressed and penetrating skull fractures seen in these cases numbered 46 (14%), of which 42 were males and 4 females. The weapons most commonly used were blunt objects (16), knives (11), guns (6) and axes (4). Gunshots contributed to 4 of the 7 deaths. 4 out of the 7 deaths were due to primary brain injury and 3 were due to infection. CONCLUSION: Open depressed fractures and penetrating injuries form a small but significant group in the management of head injuries. The use of blunt objects, firearms and arrows coupled with increasing urban violence is responsible for most of these injuries. The outcome of patients admitted who are fully conscious is expected to be good. They can be managed by prompt debridement of the wound, elevation of the fracture and removal of fragments as appropriate. However, the mortality rate is high in those with a Glasgow Coma Score of 8 or less on admission, a finding indicative of the severity of brain injury beneath the wound.

BACKGROUND: Traumatic brain injury (TBI) has been responsible for 25-30% of surgical deaths in Port Moresby General Hospital (PMGH) over the last 30 years despite being responsible for only 5% of the admissions. AIM: To document the epidemiology of TBI over a period of two years from 2003 to 2004 and compare this to the previous two decades in PMGH and elsewhere. The treatment and outcome of TBI cases are analyzed. METHODS: All TBI cases were included from January 2003 to December 2004. The Glasgow Coma Score (GCS) and Glasgow Outcome Scale (GOS) were documented at admission and discharge. These cases were followed up in the outpatient department for at least 6 months. RESULTS: There were 262 cases of TBI admitted between January 2003 and December 2004. There were 31 deaths during this period. 28 deaths were in the severe TBI category (GCS 3-8) and 3 in the moderate category (GCS 9-12). CONCLUSION: The case fatality rate of severe TBI has been reduced from 60% to just below 30% over the period of 2 years. The formation of a single unit managing TBI over two years may be one factor contributing to this improvement. Interpersonal violence has replaced motor vehicle accidents as the leading cause of death from TBI.

BACKGROUND: Hydrocephalus is a common neurosurgical problem in Port Moresby General Hospital (PMGH) contributing to 27 (24%) of the 114 neurosurgical operations done in 2003 and 2004. During the same period it was responsible for 25% of the cases seen in the neurosurgery clinic. AIM: To prospectively audit and follow up hydrocephalus cases in PMGH over 2 years from January 2003 to December 2004 and ascertain the causes and the outcome of treatment. METHOD: All cases of hydrocephalus seen in 2003 and 2004 were categorized according to cause. The associated findings on ultrasound scan or CT (computed tomography) scan when available were noted. The subsequent progress was documented with and without treatment for at least 6 months. RESULTS: 61 cases of hydrocephalus were seen for surgical opinion. The age ranged from 4 weeks to 56 years. The commonest age group affected was in the first year of life (61% of cases). There were 34 cases (56%) of congenital hydrocephalus followed by 19 (31%) post meningitis and 8 (13%) due to tumour. There was only one case of myelomeningocele with concomitant hydrocephalus. Ventriculoperitoneal (VP) shunts were inserted in 24 cases. 3 shunts were bypasses from the posterior horn to the cisterna magna, making a total of 27 shunt operations. 9 shunts were performed for post-meningitic hydrocephalus, 15 for congenital stenosis and 3 for a posterior fossa tumour. 24 out of the 27 shunt operations were in children aged <9 months. Post-VP-shunt infection of 2 cases reported within 6 weeks of operation gave an infection rate of 7%. There was cerebrospinal fluid (CSF) leak in 2 cases with Pundez-type shunts. There were 2 shunt blocks needing revision. CONCLUSION: Shunt operations can be done in PMGH with good outcomes. The decision-making about surgery can be made on the basis of the enlarging head and the ultrasound findings.

Head injuries are the commonest cause of death in the surgical wards in Port Moresby and the commonest cause of death in road accidents. Three prospective and retrospective studies performed over the last decade aimed to determine the pathology and outcome in 274 head injuries admitted to Goroka in 1988-1991 (4 years) and Port Moresby in 1984-1985 and 1992-1993 (total 2.5 years). Head injuries were managed by general surgeons without CT scanning or intracranial pressure monitoring. There were 196 adults and 78 (28%) children; 195 were male and 79 female. Assaults (32%), motor vehicle accidents (49%) and falls (17%) were the commonest modes of injury. The case fatality rate was 21% (57 of 274 cases). Six of the deaths were avoidable. The fatality rates for admission Glasgow Coma Scores of 3-5, 6-8 and over 9 were 81%, 21% and 3% respectively. Two patients died of infection complicating open depressed fractures. The case fatality rate for extradural haematoma was 20% and subdural haematoma 67%. Nine patients died of associated abdominal injuries. Most of the deaths were unavoidable because of the severity of primary brain injury. The speed of diagnosis and quality of care could have been improved but the most important area is management of the airway. General surgeons properly trained in trauma care (which includes emergency airway management) are well able to cope with the majority of head-injured patients in Papua New Guinea.

Two cases of spinal tuberculosis (TB) presented with deteriorating myelopathy despite chemotherapy. Surgery of anterior decompression and fusion was successfully carried out resulting in both the patients ambulating and being continent on discharge. This highlights the importance of early surgery and a multidisciplinary approach to the management of this condition.

A case is presented of acute spinal cord compression by a thoracic dumbbell spinal schwannoma in a young woman with neurofibromatosis type 1 (NF-1). A successful outcome was achieved with total excision of the lesion and decompression of the spinal cord. Greater recognition of the reversibility of spinal cord compression in the developing world is necessary to reduce major permanent morbidity.
