Background: Psoriasis is a chronic inflammatory, immune-mediated systemic disease with skin manifestations that typically follow a relapsing and remitting course. The most common form, plaque psoriasis, occurs in ∼80–90% of psoriatic patients. Objective: The aim of the current work was to evaluate level of serum testosterone in psoriasis male patients and its relation to severity of the disease. Patients and methods: This cohort study included a total of 35 psoriatic patients, attending At Outpatient Clinic, Dermatology and Venereology Department, Zagazig University Hospital, Egypt. This study was conducted between January 2020 to October 2020. Serum free and total testosterone and total cholesterol were measured. Result: About two thirds of the studied group (71.4 %) had normal testosterone level and (28.6 %) had low testosterone level. Conclusion: Low serum total and free testosterone levels in male psoriasis patients are present and they correlate with disease severity.

The Hemisphere Plasma Focus Device, a new construction of plasma focus devices is constructed and operated with total energy of 7.7 kJ. The discharge takes place between two concentric hemispherical electrodes. The plasma sheath is accelerated and confined by electromagnetic force. Rogowiski coil and potential divider are used to characterize the discharge current, the discharge voltage and obtain the pinch effect in shape of sharp crevice. The deposited energy is about 31.5% of the input energy for 6kV charging voltage. The total system inductance is about 285 nH with low resistance of about 23 mΩ. The plasma inductance has maximum value at the pinch time. The pinch time decreases by increasing input energy and also by decreasing the helium gas pressure. The average sheath velocity varies in range between 1.5 and 2.7 cm/µs which indicates that the charge state is about 2 and plasma temperature should mostly be over 11.2eV.

Background: Epilepsy and headache are the two most common neurologic disorders affecting individuals of all ages worldwide. The relation between headache and epilepsy is complicated, and the comorbidity of headache and epilepsy is still poorly understood. Aim of the work: Study of headache characteristics in controlled and uncontrolled epileptic patients. Methods: We evaluated headaches in 100 consecutive patients with epilepsy attending the outpatient clinic and epilepsy clinic at Sohag university hospital and performed interictal EEG to all patients. Results: In our study we found that the occurrence of headaches being linked to longer duration of epilepsy, high frequency of seizures and use of polytherapy of antiepileptics. Conclusion: Control of seizures in epileptic patients help in controlling headaches and decrease its frequency.
