Introduction: Small scale artisanal mining which is also called gold panning is rampant in gold rich areas in Zimbabwe.
Objectives: This is a study of the nature and extent of neurosurgical injuries affecting miners and an evaluation of their financial means to access medical facilities.
Design: This was a cross-sectional observational study carried out to study the neurosurgical injuries seen at Parirenyatwa Hospital.
Materials and Methods: The setting was the Neurosurgical Unit at Parirenyatwa hospital. The study period was January 2014 to December 2016. Data was collected at discharge onto a datasheet with subsequent computer analysis.
Results: A total of 36 patients were seen during the study period following artisanal mining related neurosurgical injuries. Thirty-four (34) of them were male (94.4%) while two (2) were female (5.6%).The age range was 20-45 years.

Cardiovascular disease is a leading cause of mortality in all ages worldwide. Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease (CHD) accounting for 10%. There have been several reports of neurological complications associated with TOF. Although it is known, brain abscess (BA) is a serious complication in patients with uncorrected CHD mostly in the age of 4-7 years-old. We report a case of a 7 year old male who presented with a 3 month history of left sided body weakness and a 3 week history of a headache and fever. Patient was chronically unwell since birth where he would experience occasional episodes of exertional dyspnoea which was never investigated. Chest xray showed a globular-shaped heart. CT scan brain showed a 1,8 x 1,3 x 1,5 cm ring-enhancing lesion in the right parietal region with minimal perilesional vasogenic edema communicating with the body of the lateral ventricle, with enhancement of the ependymal lining of the ventricle; echocardiography revealed ventricular septal defect (VSD), overriding of aorta, obstruction to right ventricular outflow tract and hypertrophy of right ventricle consistent with a diagnosis of TOF. We elected to manage the patient conservatively on intravenous antibiotics, Patient improved significantly neurologically and was transferred to the cardiothoracic surgeons for further management of TOF.

Introduction: Neuromodulation in its various forms is emerging as a promising method of dealing with chronic pain and movement disorders. e scale of ablative vs augmentative procedures seems to be tilting towards augmentative procedures. We observed 8 patients who had failed medical treatment for muscle spasm respond to the cold application. Case summary: We report 2 cases of complete traumatic spinal cord injury patients, who developed severe, medically intractable muscle spasms. We applied cryotherapy to their legs with signi cant improvement. Outcome measurements: e spasm frequency score dropped immediately from a 4 to 0 in one patient. e other dropped from a 2 to 1 on day one then disappeared by day 7. Spasm severity dropped signi cantly on the rst day in both cases. Conclusion: Cryotherapy as a form of neuromodulation, Is an e ective, simple but safe way to symptomatically man- age severe medically refractory muscle spasms in spinal cord injured patients. It becomes an important adjunct in the management of these patients in resource-limited settings where surgical options are not readily available.

Phenytoin toxicity masquerading as deterioration of neurological symptoms caused by interaction with chloramphenicol is a very rare but real risk. To the authors' knowledge only one such case occurring in 1 humans has been reported in the English literature. No case of clinical phenytoin toxicity occurring at less than double the serum phenytoin therapeutic levels, occurring as a result of chlorampenicol interaction has been documented, hence our report. A 17 year old man, whose frontal subdural empyema had been drained, had his seizures well controlled on phenytoin. Shortly after, he had a parasagital subdural empyema which was also drained. He was put on chloramphenicol. He improved tremendously until he then developed cerebellar symptoms. Phenytoin levels were noted to be almost twice the maximum therapeutic value. On stopping chloramphenicol, phenytoin levels normalized and symptoms resolved. Possibility of phenytoin toxicity should always be entertained in patients who are also taking chlorampenicol, presenting with new or worsening neurological symptoms.
