Clinical podiatric medical practice encompasses a wide spectrum of podiatric medical and surgical problems. Technological advances such as imaging have greatly improved diagnostic acumen; however, physical diagnosis and blood testing remain extremely important factors in reinforcing diagnostic hypotheses as a part of differential diagnosis. There are certain blood tests of importance that the podiatric medical practitioner should be familiar with in everyday medical and surgical practice. The purpose of this article is to identify and highlight which blood tests are truly essential and practical in terms of diagnosis. This article encompasses blood tests pertinent to the clinical areas of hematology, hemostasis, electrolytes, endocrine, cardiac, rheumatology, nephrology, and gastroenterology. Careful selection of these tests and proper interpretation of their results will help reinforce diagnostic hypotheses.
Podiatric Adverse Events and Foot Care in Cancer Patients and Survivors
Awareness, Education, and Literature Review
Cancer is one of the leading causes of mortality and morbidity worldwide. Recent improved therapies have resulted in more patients surviving cancer and living longer. Despite these advances, the majority of patients will develop adverse events from anticancer therapies. Foot alterations, including nail toxicities, hand-foot syndrome, edema, xerosis, hyperkeratosis, and neuropathy, are frequent among cancer patients. These untoward conditions may negatively impact quality of life, and in some cases may result in the interruption or discontinuation of cancer treatments. Appropriate prevention, diagnosis, and management of podiatric adverse events are essential to maintain foot function and health-related quality of life, both of which are critical for the care of cancer patients and survivors. This article shows results related to complaint and impact on quality of life of the Oncology Foot Care program and reviews publications specific to podiatric adverse events related to cancer treatments.
Recently, there has been a resurgence of interest in potential phototherapy technologies for the local treatment of bacterial and fungal infection. Currently, onychomycosis is the principle disease that is the target of these phototherapies in podiatric medicine. Some of these technologies are currently undergoing in vitro and in vivo trials approved by institutional review boards. The three light-based technologies are ultraviolet light therapy, near infrared photo-inactivation therapy, and photothermal ablative antisepsis. Each of these technologies have markedly dissimilar mechanisms of action. In this review, each technology will be discussed from the perspectives of history, photobiology, individual mechanism of action, safety, and potential clinical efficacy, with data presented from published material. This review is intended to give podiatric physicians detailed information on state-of-the-art infectious disease phototherapy. (J Am Podiatr Med Assoc 99(4): 348–352, 2009)
Fever is an active yet nonspecific response of the body to infections and other insults that cause immune cells to release cytokines, resulting in a brain prostanoid–mediated rise in body temperature. The causes, types, clinical management, and postoperative consequences of fever are reviewed in this article. Physicians use fever as a clinical sign for diagnoses and prognoses, but “fevers of unknown origin” continue to be problematic. Fevers that arise 1 or 2 days after surgery are usually due to stress and trauma, but later postoperative fevers often have more serious causes and consequences, such as wound infection. Fever is commonly encountered by podiatric physicians and surgeons, and certain procedures with the lower extremity are more likely to eventuate in fever.

Antibiotic Stewardship
The Lower-Extremity Physician's Prescription for Effectively Treating Infection
The discovery of antibiotic drugs was one of the most significant medical achievements of the 20th century. The improper use of antibiotic drugs to prevent and treat infections has resulted in the emergence of resistance. Antimicrobic stewardship programs are becoming a mainstay in the fight against multidrug-resistant organisms. Individual clinicians should be encouraged to adopt the principles of antibiotic stewardship when treating lower-extremity infections in their scope of practice. First, a review of the available literature outlining the concept and practice of antibiotic stewardship is offered. Second, a discussion describing how to adopt and apply these principles to the individual clinician's practice as it applies to lower-extremity infections is offered. Finally, specific antimicrobial pharmacologic spectra and antibiogram information are offered.
The effect of lower-extremity pathology and surgical intervention on automobile driving function has been a topic of contemporary interest in the medical literature. The objective of this review was to summarize the topic of driving function in the setting of lower-extremity impairment. Included studies involved lower-extremity immobilization devices, elective and traumatic lower-limb surgery, chronic musculoskeletal pathology, and diabetes as it relates to the foot and ankle, focusing on the effect each may have on driving function. We also discuss the basic US state regulations with respect to impaired driving and changes to automobile structure that can be made in the setting of lower-extremity pathology.
Lower-Extremity Sclerotomes
Clinical Applications and the Modified Mayo Block
A sclerotome is an anatomical concept that defines an area of bone supplied by a single spinal nerve. Similar to the familiar dermatomes, sclerotomes provide an element of depth to the sensory innervation of the lower extremity based on the deep fascia as an embryologic boundary. Anatomical knowledge of sclerotomes can be used clinically in the diagnosis and treatment of pain and in the perioperative setting. Specifically, a modified version of the classic Mayo block is presented to highlight an active anatomical approach to peripheral nerve blockade. (J Am Podiatr Med Assoc 99(3): 232–235, 2009)
Posterior Tibial Tendon Dysfunction
A Review
Posterior tibial tendon dysfunction is a progressive deformity that can result in the development of a pathologic flatfoot deformity. Numerous publications have studied the effects of clinical interventions at specific stages of progression of posterior tibial tendon dysfunction, but there is still uncertainty regarding the clinical identification of the condition. It is clear that more information regarding the etiology, progression, and risk factors of posterior tibial tendon dysfunction is required. Clear evidence exists that suggests that the quality of life for patients with posterior tibial tendon dysfunction is significantly affected. Furthermore, evidence suggests that early conservative intervention can significantly improve quality of life regarding disability, function, and pain. This would suggest that significant cost burden reductions could be made by improving awareness of the condition, which would improve early diagnosis. Early conservative intervention may help reduce the number of patients requiring surgery. This review focuses on the etiologic factors, epidemiologic features, and pathogenesis of posterior tibial tendon dysfunction. It aims to analyze, discuss, and debate the current understanding of this condition using the available literature. In addition, there is a discussion of the evidence base surrounding disease characteristics associated with the different clinical stages of posterior tibial tendon dysfunction.

Clinical Assessment of Ankle Joint Dorsiflexion
A Review of Measurement Techniques
Ankle dorsiflexion measurement is important for clinical and research use. With so much evidence on the unreliability of goniometric measurements, a systematic review was performed to investigate various alternative techniques for measuring ankle dorsiflexion in the nonneurologic patient. All of the major databases were queried electronically to identify studies that used any method of ankle dorsiflexion measurement in the nonneurologic subject. Keywords included ankle dorsiflexion NOT cerebral palsy NOT stroke, the latter to exclude neurologic conditions. In 755 studies that used some form of ankle joint dorsiflexion measurement, ten different techniques were identified that included various apparatuses designed specifically for this purpose. Reliability testing of these techniques involved test-retest trials with small student populations as subjects, which returned high intraclass correlation coefficient scores. However, their methodological quality would have benefitted from the use of an actual patient population and comparison with a reference standard. When validating ankle dorsiflexion measurement techniques, actual patient populations should be used, otherwise papers would score poorly on methodological quality assessment. Standardizing patient position, foot posture, amount of moment applied, and reference landmarks will ensure that various trial results can be compared directly.

Subungual Exostosis
Systematic Review and Meta-Analysis
Background:
The coexistence of deformity of the nail bed and subungual exostosis (SE) is a frequent finding in podiatric practice in the fourth and fifth decades of life. However, it has been described by other specialists as being an uncommon osteocartilaginous tumor most prevalent during the second and third decades of life. This study attempts to determine the causes of this discrepancy.
Methods:
Two authors independently conducted a systematic bibliographic review in multiple databases, podiatry sources and others, and key words were chosen to achieve a broad search strategy. Studies reporting on epidemiology and treatment of SE lesions in lower extremities in ten or more patients were selected. Initially, 197 articles were identified through database screening, with 23 meeting all inclusion and exclusion criteria. Seven articles with the ages of all of the patients were included in the analysis of age data. A comparison was then made between the diagnostic criteria for the selected 23 articles.
Results:
Model results reveal that, although there are some significant differences between individual studies, the main factor tested (patient's age) was clearly significant (F1,5.2 = 78.12, P < .001), showing that studies coming from the podiatry speciality were conducted on individuals with a mean age of 37 years higher than in studies from other specialties. Clinical and radiologic characteristics and treatment described in the podiatry literature also contrast with those in other specialties.
Conclusions:
The SE described by podiatrists, in accordance with the parameters of true exostosis, is different from Dupuytren's SE and should be considered as a different pathologic entity. The authors are working on its histologic identification.
