Review Meta Analysis
Influence of greater occipital nerve block on pain severity in migraine patients: A systematic review and meta-analysis.
Greater occipital nerve (GON) block may be a promising approach to treat migraine. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the efficacy of GON block in migraine patients. ⋯ Compared to control intervention, GON block intervention can significantly alleviate pain, reduce the number of headache days and medication consumption, but have no significant influence on the duration of headache per four weeks for migraine patients.

Myiasis designates the infestation of live human and vertebrate animals with dipterous (two-winged) larvae (maggots) and is the fourth most common travel-associated skin disease. Furuncle is the most common aspect of cutaneous myiasis. ⋯ There is an increase in travelers returning from tropical countries. Consequently, travel-associated dermatoses are increasing in non-endemic countries. Context of travel and typical clinical presentation strongly suggested to evoke a cutaneous myiasis. The typical furuncular lesion is a papule or nodule with a central punctum that exudes serosanguinous or purulent fluid. Ultrasound can be used to confirm the diagnosis. Treatment consists of three techniques: methods producing localized hypoxia to force emergence of the larvae, application of toxic substances to the eggs and larvae, and mechanical or surgical debridement. Surgery and antibiotics are usually unnecessary. Prevention of furunculous myiasis is based on vector control and individual actions to improve hygiene.

It is unclear whether scene time interval (STI) is associated with better neurological recovery in the emergency medical service (EMS) system with intermediate service level. ⋯ The middle STI (4-7min) was associated with the highest odds of neurological recovery for patients who could not be restored in the field. The STI may be a clinically useful predictor of good neurology outcome in victims of cardiac arrest.
