Objective: Hypochlorous acid (HOCl) is a highly microbiocidal agent active against bacteria, viruses and fungi. Using quantitative microbiology, preliminary studies showed it achieved an appreciable reduction in the bacterial burden in chronic venous leg ulcers. The study aimed to determine whether it has a role as an additional treatment for chronic venous ulcers that have not healed with conventional treatment.
Method: On the basis of previous reports we designed a study in which patients acted as their own controls, in that only patients who failed to achieve a 44% reduction in wound size with standard treatment (compression bandaging) received HOCl washes.
Results: Of 30 patients admitted to the study, 10 achieved a 44% ulcer reduction after three weeks of standard treatment. In addition to the standard compression treatment, the remaining 20 patients were given HOCl washes over 12 weeks. Of the 20 ulcers, nine (45%) healed and five (25%) reduced in size by over 60%. All patients became free of pain.
Conclusion: These findings confirm the clinical efficacy of treating venous leg ulcers with hypochlorous washes. Use of HOCl washes as an adjunctive therapy for recalcitrant venous leg ulcers appreciably increases healing and rapidly relieves pain.

The size of comb cells is a key factor influencing the body size of honey bee workers. Comb cells and the body size of Chinese honey bee workers are smaller than those of Italian honey bee workers. To increase the size of Chinese honey bee workers, this study used newly built combs from Chinese honey bee colonies (control group) and Italian honey bee colonies (treatment group).

Purpose: To report the occurrence of acute postrenal kidney failure caused by external ureteral obstruction after iliac venous stent placement.
Case Report: A 73-year-old male patient presented with a chronic swelling and feeling of heaviness of his right leg. The presence of venous thrombosis was excluded by duplex ultrasound (DUS).

Department of Perinatology, Ankara Etlik City Hospital, Ankara, Turkey.
Aims: This study aimed to investigate the predictive value of the platelet indices for the diagnosis of acute deep vein thrombosis (DVT) in pregnant women.
Materials And Methods: Pregnant women aged 20-45 years who presented to the emergency room with leg pain and edema and underwent bilateral lower extremity venous Doppler examination for DVT were included in the study. Platelet large cell ratio (P-LCR), platelet distribution width (PDW) and mean platelet volume (MPV) values, which provide information on current platelet activity in the hemogram parameters recorded at first presentation in the emergency department, were analyzed between the two groups.

Objective: To determine if intermittent neuromuscular electrostimulation (NMES) of the common peroneal nerve increases microvascular flow and pulsatility in and around the wound bed of patients with combined venous and arterial etiology.
Methods: Seven consenting participants presenting with mixed etiology leg ulcers participated in this study. Microvascular flow and pulsatility was measured in the wound bed and in the skin surrounding the wound using laser speckle contrast imaging.

This case report presents a 16-year-old basketball player, who developed deep venous thrombosis (DVT) following surgical intervention for a displaced tibial tuberosity fracture and forearm fractures. Despite few identifiable thrombotic risk factors, the patient's postoperative course was complicated by unexplained leg pain, fever, and ultimately confirmed DVT. Prompt management with therapeutic anticoagulation and multidisciplinary care led to favourable outcomes.
