Physical examination of any swelling is the first step in making a diagnosis. Many a times we see a patient with a spherical swelling, which is usually a cyst. The interpretation of physical signs should be based on sound principles of physics. In the present paper, we explain physical characteristics of a swelling (cyst) using principles of fluid mechanics.

Srinivas R Rami Reddy, Mitchell S Cappell
PURPOSE OF REVIEW: This study aimed to systematically review small bowel obstruction (SBO), focusing on recent changes in diagnosis/therapy. RECENT FINDINGS: SBO incidence is about 350,000/annum in the USA. Etiologies include adhesions (65%), hernias (10%), neoplasms (5%), Crohn's disease (5%), and other (15%). Bowel dilatation occurs proximal to obstruction primarily from swallowed air and secondarily from intraluminal fluid accumulation. Dilatation increases mural tension, decreases mucosal perfusion, causes bacterial proliferation, and decreases mural tensile strength that increases bowel perforation risks...

Masseter muscle hypertrophy is an untypical anomaly with no definite cause and its diagnosis is easily completed through physical examination and imaging examinations. In some cases, patient may report signs and symptoms of well-localizated pain. However, it is generally asymptomatic and patient's chief complaint is about esthetic because of facial asymmetry. In this case, surgery is carefully indicated. The aim of this article is to report a case of a male patient with no painful and functional complaints but an important unease over his facial asymmetry...

Frederick M Burkle
Triage management remains a major challenge, especially in resource-poor settings such as war, complex humanitarian emergencies, and public health emergencies in developing countries. In triage it is often the disruption of physiology, not anatomy, that is critical, supporting triage methodology based on clinician-assessed physiological parameters as well as anatomy and mechanism of injury. In recent times, too many clinicians from developed countries have deployed to humanitarian emergencies without the physical exam skills needed to assess patients without the benefit of remotely fed electronic monitoring, laboratory, and imaging studies...

The diagnosis of chronic obstructive pulmonary disease (COPD) should be suspected in patients with risk factors (primarily a history of smoking) who report dyspnea at rest or with exertion, chronic cough with or without sputum production, or a history of wheezing. COPD may be suspected based on findings from the history and physical examination, but must be confirmed by spirometry to detect airflow obstruction. Findings that are most helpful to rule in COPD include a smoking history of more than 40 pack-years, a self-reported history of COPD, maximal laryngeal height, and age older than 45 years...

BACKGROUND: Castleman's disease is a rare lymphoproliferative disorder of unknown etiology that most commonly presents as a mediastinal nodal mass. It is exceptionally uncommon for Castleman's disease to present in the mesentery and, only 53 cases have ever been described in the literature. Standard treatment for this lymphoproliferative disorder involving a single node is a complete "en bloc" surgical resection which has proven to be a curative approach in almost all cases without recurrence after 20 years of follow up...

INTRODUCTION: Among urologic diseases, ureteropelvic segment stenosis with hydronephrosis is a common indication for instrumental or surgical correction. The restriction of urine flow with dilatation proximal to obstruction develops in 6.5-37% of cases at different times after the ureteral reconstruction. All this urges to develop and improve stents and search for effective ways to place stents and control their function. AIM: To investigate the effectiveness of polyhydroxyalkanoates based biodegradable stent compared with a commercial analogue in upper urinary tract drainage after ureteropelvic segment pyeloplasty...

In Denmark, patients with serious nonspecific symptoms and signs of cancer (NSSC) are referred to the diagnostic outpatient clinics (DOCs) where an accelerated cancer diagnostic program is initiated. Various immunological and inflammatory biomarkers have been associated with cancer, including soluble urokinase plasminogen activator receptor (suPAR) and the pattern recognition receptors (PRRs) pentraxin-3, mannose-binding lectin, ficolin-1, ficolin-2 and ficolin-3. We aimed to evaluate these biomarkers and compare their diagnostic ability to classical biomarkers for diagnosing cancer in patients with NSSC...

Hip dysplasia is a common developmental disorder of the dog, consisting of varying degrees of hip laxity, progressive remodeling of the structures of the hip, and subsequent development of osteoarthritis. It is a juvenile-onset condition, with clinical signs often first evident at 4 to 12 months of age. A tentative diagnosis of hip dysplasia can be made based on signalment, history, and physical examination findings. The Ortolani test is a valuable tool for identifying juvenile dogs affected with this condition...

Management of the athlete with postconcussion syndrome (PCS) is challenging because of the nonspecificity of PCS symptoms. Ongoing symptoms reflect prolonged concussion pathophysiology or conditions such as migraine headaches, depression or anxiety, chronic pain, cervical injury, visual dysfunction, vestibular dysfunction, or some combination of these. In this paper, we focus on the physiological signs of concussion to help narrow the differential diagnosis of PCS in athletes. The physiological effects of exercise on concussion are especially important for athletes...
