The presence of a venous pumping mechanism in the foot may be significant for venous return in the lower extremities. However, there has been a lack of conclusive research in the area to date and controversy still exists over the detailed anatomy and physiologic mechanism of the venous foot pump. A full understanding of the anatomy and physiology of the venous foot pump is essential for designing effective interventions for the prevention, treatment, and management of venous disease in the lower limbs. This article highlights and discusses the relevant literature relating to the anatomy and physiology of the venous foot pump. In addition, the plantar aspects of 10 cadaveric feet were dissected. These dissections revealed the presence of a previously unreported secondary deep plantar arch and/or deep system of venous connections in the foot and facilitated a more detailed description of the patterns of doubling and branching of the primary veins of the foot. The results of these dissections are discussed within the context of previous work in the field with the aid of detailed diagrams of the dissected feet and may provide a backdrop for the physiology of the venous foot pump and its potential role in lower limb circulation. This is discussed in the last section of the article, which also highlights existing controversy regarding the role of weight bearing and muscular contraction as the dominant mechanisms for venous pumping in the foot.

At ESIC Medical College & Hospital, Faridabad, Haryana, India, Shanta Passi, MD, is Associate Professor, Department of Dermatology, Venereology, & Leprology; Deepika Uikey, MD, is Assistant Professor, Department of Dermatology, Venereology, & Leprology; and Manoj Kumar, MD, is Assistant Professor, Department of Psychiatry.
Background: Infective and noninfective dermatoses of the lower leg and foot can be attributed to factors such as infections, blood stagnation, chemical contact, and abnormal mechanics. These factors make the lower leg and foot more susceptible to microbial infections, contact dermatitis, stasis eczema, ulcers, corns, and calluses.
Objective: To identify the patterns of infective and noninfective dermatoses on the lower leg and foot.
Primary Antiphospholipid Syndrome Causing Critical Limb Ischemia and Ultimately Amputation in an Otherwise Healthy Young Female.

†Arbor-Ypsi Foot and Ankle Centers, Ann Arbor, Michigan.
This case report describes an otherwise healthy 43-year-old female who presented with severe pain, foot drop, and critical limb ischemia to her left foot caused by thrombosis of a peripheral artery secondary to antiphospholipid syndrome. Antiphospholipid syndrome is an autoimmune disease that frequently manifests as recurrent arterial and/or venous thrombotic events, ischemic strokes, and miscarriages. Antiphospholipid syndrome affecting primarily the arteries is less common as compared to venous thrombosis.

The Charles procedure (CP) is a potentially devastating treatment; however, in cases of an end stage of untreated or improperly treated lymphedema, it is the ultimate surgical therapy. As a life-saving solution, it quickly relieves patients with giant, hypertrophic extremities, mostly in ambulation and hygiene maintenance. Nevertheless, long-term results may disappoint both doctors and patients, who struggle with social stigma, the need for lifelong compression, massive lymphoedema in the distal parts of the feet, badly fitting shoes, excessive skin fibrosis, severe keratinization of skin-grafted surfaces, periodic lymphorrhea from the resected areas, or acute and chronic inflammation.

Objective: The surgical team in this study examined the efficacy of a modified reverse sural neurocutaneous flap repair in treating soft tissue defects of the ankle and foot caused by accidents.
Methods: This study enrolled 89 patients treated for soft tissue defects of the ankle or foot between January 2007 and December 2023. The patients were divided into two groups: 44 patients underwent a modified reverse sural neurocutaneous flap repair, while 45 received traditional treatment.
The Dermatologic Oral Examination: Navigating the Oral Dermatoses Map.

Mayo Clinic Arizona, Department of Dermatology, Scottsdale, AZ, USA.
Traditionally, dermatological education emphasizes hair, skin and nails in its curriculum. There is a practice gap with regard to knowledge of normal oral mucosa variants, performance of the oral examination, and competence in diagnosing and treating oral mucosal disorders. The oral mucosa falls within the purview of dermatology.
