Neoplastic growth of cerebral cavernous malformation presenting with impending cerebral herniation: A case report and review of the literature on de novo growth of cavernomas

Background: Cerebral cavernomas are rare vascular anomalies and their expansile growth has been considered to be mainly due to recurrent hemorrhages. They are not generally reported to show aggressive behavior.Case description: A 27-year-old male presented with headache, visual disturbances, and a 17-year history of seizures. He was known to have a temporal lobe lesion on CT scan, consistent with a diagnosis of cavernous malformation but with no relevant family history. Serial clinical and radiological follow-up revealed a progressive increase in the size of the lesion with formation of a growing cyst of 7 cm in diameter, which produced mass effect, resulting in the clinical picture of cerebral herniation. The patient underwent emergency surgical resection with symptomatic relief. There was no evidence of significant hemorrhage at surgery.Conclusion: Cavernous malformations can show expansile growth without any evidence of a presaging hemorrhagic event and, in the manner of a neoplastic lesion, present with raised intracranial pressure and cerebral herniation

Surgery for prolactinomas

A large proportion of prolactin secreting tumours of the pituitary gland are treatable by dopamine agonist drugs. however certain subgroups of these patients are better managed by surgical excision. the indications for surgery in prolactinomas remain controversial and this paper attempts to clarify these with illustrative cases. the factors favouring a surgical approach include poor tolerance of long term medical therapy, progression of visual deficits or recurrence while on medical treatment, cystic change in the tumour with pressure effects, csf fistula secondary to tumour shrinkage and prophylactic surgery in tumours anticipated to cause csf leak following medical therapy. the size and invasiveness of the tumour and the prolactin level are also important determinants of treatment planning. the indications for surgery in prolactinomas are discussed and illustrative cases are presented

Trans-mastoid approach to otogenic brain abscess

The treatment of otogenic brain abscess initially involves excision or aspiration of the abscess through a temporal or sub-occipital route depending on its location. This is followed by a mastoidectomy by the ENT surgeon to eradicate the primary source of infection. During the last three years, we have approached such lesions through a mastoidectomy followed by excision of the abscess through the same approach. This trans-mastoid approach is technically feasible in following the tract of suppuration, and clearing the cause and effect of pathology, at the same sitting. This paper describes our initial experience with the trans-mastoid approach to otogenic brain abscesses. On the basis of our results, we believe that transmastoid approach is an effective and logical option for the treatment of otogenic brain abscess, and merits further investigation in the form of a prospective study

Management of myelomeningocele

Objective: T To find out best possible protocol to provide productive life to children born with myelomeningocele.Study design: Descriptive study.Place & Duration of study: Department of Neurosurgery, Jinnah Postgraduate Medical Centre Karachi from December 2001 to December 2006.Patients and Methods: The medical record of 415 children with myelomeningocele operated at our center was reviewed retrospectively. The surgical & medical management protocol used for different sites of myelomeningocele was studied.Results: The age of most of the patients at the time of myelomeningocele repair was between 25-30 days; however, children with ruptured myelomeningocele were consistently repaired early. All paraplegic patients with dorsolumbar myelomeningocele were treated with either a low-pressure ventriculoperitoneal (VP) shunt only, direct repair or both. Patients with cervical, dorsal and lumbo-sacral myelomeningocele requiring VP shunt were operated either simultaneously for both procedures or with delayed insertions of a VP shunt after treatment of ventriculitis All 16 patients with ruptured myelomeningocele (3.8%) were treated for repair as well as ventriculitis. Complications including CSF leak, wound infection or necrosis after repair of myelomeningocele occurred in 22 cases (5.3%). The postoperative follow up for all patients was 1- 2 years.Conclusions: Surgical intervention with a low-pressure VP shunt in large dorsolumbar myelomeningocele produced good results

Effectiveness of helmets in preventing severe injuries in a setting with poorly enforced quality standards

Helmets save lives, yet many countries do not have laws about their quality assessment or how they should be worn. We assessed the effectiveness of helmet use in preventing injuries in such a setting. The data were extracted from a large road traffic injury surveillance study in Karachi, Pakistan. We assessed the association of wearing helmets with several injury outcomes including deaths, injury severity (via New Injury Severity Score, NISS ≥ 9) and moderate or severe injury (via Abbreviated Injury Score, AIS ≥ 2) to head, face, or other regions of the body. The data about helmet use was available for about 109,210 riders injured between January 2007 and December 2013. Only 6% of riders wore helmets, whereas this proportion was less than one percent in pillion riders and women. The rates were also lower among those aged 18 years or younger (1%) and those aged 18 to 25 years (4%). About 2% of riders died; 34% had an injury to the head region, 30% to face, 1% to chest, 5% to abdominal, 46% to extremities, and 61% to external body regions. Likelihood of dying was low among helmet users (adjusted odds ratio [aOR] = 0.37, 95% confidence interval [CI] = 0.28 to 0.50). Helmets reduced the likelihood of moderate to severe injuries to the head (aOR = 0.68, 95% CI = 0.58 to 0.80) but not to the face region (aOR = 1.37, 95%CI = 1.17 to 1.62). Helmet users also had severer injuries in other body regions except for chest injuries. Helmets prevented deaths and severe head injuries but had limited effectiveness in preventing facial injuries in this setting with poor helmet use standards. More work is needed to understand the helmet wearing and rider behaviours in helmet users in this setting

Long scarf injuries

Long scarf (Dopatta) traditionally worn by females in South-East Asia have been described to make the females prone to sustain specific injuries when they ride pillion on the cycle powered rickshaw or motor bike. Two cases of females have been described

Pakistan human resources for health assessment, 2009

Pakistan faces a human resources for health (HRH) crisis. A cross-sectional survey was conducted to overview frontline health workers. A total of 750 health facilities were surveyed across Pakistan. The median estimate of public sector health care workers in the district health system in Pakistan is 417 288, including 46 153 estimate of public sector health care workers in the district health system in Pakistan is 417 288, including 46 153 doctors and 41 032 nurses. Another estimated 20 000 doctors work in public sector tertiary care hospitals across the country. A total of 3549 health care workers were interviewed regarding job satisfaction and work environment. The private sector had better work environment scores compared with the public sector. Policy dimensions showed an absence of robust policies in practice. The public sector is inadequately staffed and job satisfaction and work environment need improvement. HRH crisis countries should share experiences, and developmental partners should support them in overcoming the HRH crisis

Quality of life of road traffic injury survivors aged 15-44 years suffered from moderate and severe head injuries in Karachi, Pakistan

Background: Most of Road traffic injuries are predicted to be the third leading contributor to the global burden of disease by 2020 and patients end up into head injuries which leave devastating impacts on individual and society. Quality of Life After Brain Injury (QOLIBRI) is a specific tool that measures quality of life in head injury patients.Methods: This was a cross sectional study among 300 patients aged 15-45 years, attended emergency department of the Aga khan University Hospital. Structured questionnaire included demography, injury details, QOLIBRI, GOSE and WHO Disability Assessment Scale (WHODAS 12 items). Severity of injury was determined by Glasgow coma score of subjects reported in emergency department on admission. This was one time telephonic survey in which bidirectional data was collected from subjects about injury and outcome (QOLIBRI). To identify the determinants of QOL among RTI survivors with head injury multiple linear regressions was applied.Results: The mean QOL score for study sample was 69.86 ± (15.89. Most of the patients 210 (70%) were motorbike rider followed by four-wheelers 69 (23%). Mean age of RTI participants was 28.10 ± (7.68) years. The quality of life decreases with increase in severity of head injury by -697.32 (95% CI; -1006.44, -388.20).Conclusions: This study suggests severity of head injury, recovery time, surgery resulting from RTA, employment, family system and disability to have long term impact on QOL of RTI survivors
