Pesticides and brain cancer linked in orchard farmers of Kashmir.

Background: The atmosphere of valley of Kashmir is ideal for fresh and dry fruit production. Millions of tons of pesticides, insecticides and fungicides (chemicals like chlorpyriphos, mancozeb, captan, dimethoate, phosalone, etc.) are being used by the orchard farmers to spray the plants, fruits and the leaves every year. The increasing trend in the incidence of primary malignant brain tumors in orchard farmers of Kashmir is alarming. Aim: To determine the relationship between the patients of primary malignant brain tumors and their occupation. Materials and Methods: Retrospectively case files along with death certificates of 432 patients of primary malignant brain tumors and 457 controls (non-tumor neurologic diseases), admitted for treatment simultaneously over a period of 4 years from January 2005 to December 2008, to the Department of Neurosurgery, Sher-I-Kashmir Institute of Medical Sciences (SKIMS), Kashmir, were studied. Follow-up and family contact was established. The serum cholinesterase activity was measured by kinetic/DGKC calorimetric method and ethylenediaminetetraacetic acid (EDTA) samples were sent to the laboratory. The results are expressed in U/l which is U/l×1000. The laboratory at SKIMS, Srinagar, and Dr Lal PathLabs at New Delhi used a reference range for serum cholinesterase as 3167–6333 U/l. Results: Analysis revealed that 90.04% (389 out of 432) patients were orchard-farm workers, orchard residents and orchard playing children exposed to the high levels of multiple types of neurotoxic and carcinogenic (chlorpyriphos, dimethoate, mancozeb and captan) chemicals for more than 10–20 years. About 31.9% (124 out of 389) of these from both sexes were younger than 40 years beginning exposure at an early age and had higher (<6334 U/l) serum cholinesterase (SCE) levels. The 9.96% (43 out of 432) patients were not exposed to pesticides. On the other hand, only 119 patients out of 457 controls had recorded history of pesticide exposure and 338 were unrelated to pesticides. Out of 389 patients, 71.7% (279 out of 389) were males and 28.3% (110 out of 389) including 7 members of three families, 6 were females and 1 male. Conclusion: All orchard-related 389 patients had high grade tumors as compared to the non-pesticide tumors. Mortality in pesticide exposed tumors was 12%. Higher levels of SCE were found in 31.9% (124 out of 389) patients and decreased levels in only 45.3% (176 out of 389) orchard-related patients. The significantcase/control odds ratio (OR) of 0.28, hospital control SCE OR of 1.1 and family control SCE OR of 1.5, points the finger of suspicion toward the link between pesticides and brain cancer.

Disaster management of civilian gunshot head wounds in north Indian state

Abstract Management of 3794 gunshot wounds of head at disaster scale, who presented to our emergency room in groups continuously over a period of 20 years, by the Department of Neurosurgery at Sher-I-Kashmir Institute of Medical Sciences (SKIMS) Kashmir, India, from September 1988 to November 2008, revealed an overall mortality of 87.69% (3327 out of 3794). Patients were triaged in emergency CT-room. Most of the victims were males. Most of the deaths 79.14% (2633 out of 3327) occurred within 30 minutes of the patients arrival to the hospital and only 694 patients lived beyond one hour of arrival. Out Of total (3327) deaths, 2844 patients had admission GCS score of 3 and all of these died. No deaths occurred in the group of patients with GCS score 9-15. Poor and delayed mode of transportation accounted for 89.2% (2133 out of 2391) deaths. Elderly patients above 41 years of age in both sexes had poor outcome. 45 Children (below 18 years) were injured with a mortality of 42.2% (19 out of 45), attributing 0.57% (19 out of 3327) to total deaths. Surgical mortality was 30.9% (181 out of 585) and un-operative patients had 42.2% (46 out of 109) mortality. About 65.87% (276 out of 419) patients with admission-GCS score 4 to 8 were surgically salvageable. Predictors of poor outcome were low admission GCS score, fixed and dilated pupils, poor and delayed mode of transportation, hemodynamic instability, abnormal breathing at admission, coagulopathy and disseminated intravascular coagulation (DIC), CT visualisation of subarachnoid hemorrhage (SAH), ventricular hemorrhage, midline shift, bihemispheric and multilobar injuries and scalp wounds at occipital, temporal and frontal areas. However retained missile and bone fragments were less harmful than retained wooden (pulped mulberry stem) and cardboard wads and pneumocephalus in causing infections, cortical atrophy and seizures in the long run.

Non-metallic and metallic craniocerebral missile injuries: Varied outcome

Abstract We studied the comparative outcome related to 694 non-metallic and metallic craniocerebral missile injuries who lived at 2 hours and beyond the time of injury in a retrospective and prospective analysis in the Department of Neurosurgery at Sher-I-Kashmir Institute of Medical Sciences (SKIMS) Kashmir, India, over a period of 21 years from September 1988 to March, 2010. The study revealed an overall mortality of 32.70% (227 out of 694). A total of 664 adults and 30 children (mostly teenagers) were studied. The 79.1% (549 out of 694) patients were metallic missile injuries whereas 20.8% (145 out of 694) patients were non-metallic missile injuries. The non-metallic missile injury group mostly (72.4% i.e.; 105 out of 145) had low GCS score and overall worse prognosis with zero good-recovery, 47.5% disabilities and 52.4% mortality as compared to the metallic missile injury group. The non-metallic group comprised of 60% (18 out of 30) children with one death. Non-metallic missile injuries accounted for 10.95% (76 out of 694 patients) of total deaths. Predictors of poor outcome were low admission GCS score, non-metallic penetrating injury due to tear-gas cartridges, rubber bullets and stone-bullets, perforating metallic missile injuries and delayed and maltransportation. Most complications in non-metallic missile injuries were infective and had poor outcome. The common non-metallic missiles used were stone bullets (balls) fired by Gulail (modified catapult) or slingshot, red rubber bullets, plastic tear gas shells and cartridges, wooden (pulped mulberry stem) and card-board wads used in shotguns. The stone pelting, throwing stone projectiles (stone-bullets) by Gulail and manually has become a common way to inflict head injuries in Kashmir. The non-metallic missiles are not less-lethal and have high disabling, killing and infective potential.

Dural-stabs after wide craniectomy to decompress acute subdural hematoma with severe traumatic brain edema — An alternative technique to open dural flap

Abstract The Department of Neurosurgery Sher-i-Kashmir Institute of Medical Sciences (SKIMS) Srinagar, a single neurosurgical centre in Kashmir valley, assessed prospectively, under a uniform protocol, 120 patients of severe traumatic brain edema with acute subdural hematoma by wide decompressive craniectomy with dural-stabs in 60(cases) patients as against conventional dural opening (open dural flap) and removal of acute subdural hematoma in 60(controls) patients during a period of 3 years (June 2006 to June 2009). A free bone flap was elevated and preserved. All patients had GCS (Glassgow Coma Scale) score of 8 and less. The elective ventilation and ICP monitoring was carried out in all patients. Most patients were young and males with a mean age of 30 years in both groups. The overall survival of the dural-stab group (case-study) was 78.3% with good recovery in 43.3% and a mortality of 21.6% (13/60) as compared to 40% survival in open dural flap (control) group with 11.6% good recovery and a mortality of 60% (36/60). The conventional (open dural flap) procedure to remove the clot proved dangerous in a traumatic “vent-searching” and edematous brain, restricted in a rigid cranial vault. This midway-approach, known in SKIMS as “dural-stabs”, between the only decompressive craniectomy and removal of acute subdural clot by open dural flap (conventional) method, proved much effective in increasing survival of low GCS and severe traumatic brain edema with acute subdural hematoma. In conclusion decompressive craniectomy alone is not sufficient and open dural flap is full of risk in such patients.

Gluteal pseudophallus in a male child: A rare cutaneous marker of occult spinal dysraphism

Congenital midline paraspinal cutaneous markers have been practically linked to the location and nature of neural-tissue lesions. One of the most interesting congenital midline paraspinal cutaneous markers has been the human tail in the lumbosacral region, with underlying spinal dysraphism. Human tails have many shapes and sizes and are usually localized to the lumbosacral region. After a complete neurological examination, the MRI is the most sensitive diagnostic modality to reveal the underlying occult spinal dysraphic state. Surgical excision is aimed at untethering of the spinal cord in symptomatic children and for aesthetic reasons in asymptomatic patients. Here we report an asymptomatic male child with normal external genitilia, whose tail is attached to the gluteal region like an adult phallus and investigations revealed an underlying spinal dysraphic state.

Head injury in a child: A rare combination of three complications

A 3-year-old female child presented with a rare combination of three complications 2 months after a closed head injury. A linear skull fracture grew into a leptomeningeal cyst within 8 weeks of head injury. In addition, a large brain abscess developed and led to hydrocephalus by causing ventriculitis, thereby increasing the size of leptomeningeal cyst.
