ABSTRACT
Background : Fractional CO2 laser resurfacing in the treatment of acne scars, attempts to reduce the adverse effect of laser resurfacing by creating microscopic injury zones to the dermis with skipped interval areas.
Aim of the study : The purpose of this study is to compare the safety and efficacy of high pulse energy (70 mJ) and low pulse energy (45 mJ) of fractional CO2 laser resurfacing in the treatment of facial acne scars.
Patients and Methods : Twenty patients with moderate to severe atrophic acne scars were treated with three sessions of fractional CO2 laser resurfacing at four-week intervals with high and low energy levels applied to each side of the face separately. The severity of acne scars at baseline and after treatment was assessed using Goodman and Baron’s qualitative scar grading system. Patient satisfaction score was obtained using a quartile grading scale.
Results : The severity of acne scars on both sides was comparable to each other before the treatment (p = 0.643). At the final assessment, both sides with high and low energy levels demonstrated an excellent response (p = 0.000). However, the difference between the mean final scores of both sides was not significant (p = 0.731).  The most frequently reported side effects were crustation and erythema. Crustation lasted longer on the right side (mean = 6.75 days) whereas for the left side (mean = 5.45 days). Erythema was transient and only in four cases persisted beyond a week (right side mean = 10.5 days while left side mean = 8.75 days)
Conclusions : Both high energy (70 mJ/pulse) and low energy (45 mJ/pulse) CO2 fractional laser resurfacing of acne scar results in satisfactory outcomes with no statistically significant differences. While the duration of side effects (crustation and erythema) was increased slightly with higher fluence.

ABSTRACT
Background: Parkinson disease is a long-lasting and progressive motor disorder which is identified by three critical motor symptoms which are bradykinesia, rigidity and tremor. 
Aim of the study: To assess the histopathological changes in the brain of Parkinson disease’s patients and the regimes used for treatment.
Conclusion: Several histopathological changes in the neurons in brain of patients with Parkinson disease are α-synucleinopathies, lewy bodies, damage of synaptic neurons, and hyperactivation of microglial cell. Many regimes were used in the treatment of Parkinson disease particularly to alleviate motor symptoms. The golden goal is they should focus on preserving the synaptic neurons before they get damaged.
