Objective: To investigate the reconstructive effectiveness for chronic scalp erosion after deep brain stimulation (DBS).
Background: Deep brain stimulation (DBS) is an effective treatment for Parkinson's disease. However, this surgery is not exempt from hard-ware related complications, especially scalp erosions on scalp. Scalp erosions usually accompanied with chronic infection and wound contamination. If not arrested, infections may spread through the entire equipment which would endanger the patient's life. Along with review of previous literatures, we summarized our experience in the management of scalp erosion and implemented a systemic treatment plan for reconstruction.
Methods: We retrospectively analyzed the clinical data of patients with chronic scalp erosion after DBS in the past 40 months. The treatment plan was composed of three sequential major steps, including wound care and conservative methods, debridement and local flap, and revaluation of the wound. In each of the cases, wound debridement and local scalp flap repair were conducted, and assisted by negative pressure wound therapy (NPWT) device and double cannula irrigation.
Results: The local scalp flap survived in all 6 patients. The chronic scalp erosions all healed without refractory. The DBS devices still functioned properly after the treatments in all patients. The average follow-up period was 13.33 months (range: 4 to 23 months), and no infection recurrence or re-erosion of the scalp flap was reported.
Conclusion: A combination of wound debridement, local scalp flap repair, the use of NPWT device and double cannula irrigation provides effective treatment method for chronic erosion post DBS surgery.

Introduction: Patients with end-stage renal disease usually undergo hemodialysis as a way of renal function replacement therapy which comes with a wide array of systemic and cutaneous complications. The aim of this study was to evaluate the most frequent dermatological manifestations including xerosis, pruritis and other nail, hair and oral conditions, as these are a very important aspect to be considered while managing the patients psychological and physical needs to improve their outcomes and quality of life.
Methods: This retrospective cross-sectional study was performed by selecting 77 patients on hemodialysis based on a certain criteria and data was then collected on a sheet using patients database on Hakeem National E-Health Program, in addition to information from interviews with patients during their hemodialysis sessions after taking an oral informed consent and insuring patients' privacy.

Objective: Electroconvulsive therapy (ECT) has been occasionally applied as a treatment for super-refractory status epilepticus (SRSE). However, the effects of ECT on electrographic activity and related clinical outcomes are largely unknown. Here, we use quantitative approaches on electroencephalography (EEG) data to evaluate the neurophysiological influences of ECT and how they may relate to patient survival.

Dissecting cellulitis (DC) of the scalp is a chronic inflammatory condition marked by neutrophilic cicatricial alopecia, often linked to staphylococcal antigens. This case report details a 34-year-old male with scarring acne who developed DC following follicular unit extraction (FUE) approximately four months prior. Trichoscopic examination revealed brown pigmented dots, erythema, and melicerous crusts.

Chronic osteomyelitis of the skull base is a commonly reported pathology in existing scientific literature, but chronic osteomyelitis of the skull vault (COSV) is a rarely documented disease. We report the case of a 38 years old Afghan male with a presenting complaint of irregular swelling on the skull vault for six months. The patient had a history of head trauma one year back with a compound depressed fracture which had been surgically managed then.
