Sinus x-rays may be helpful to rule out sinusitis, but otherwise the diagnosis can usu- ally be made with history and physical. Sinusitis Bacterial sinusitis is more common in persons with a long-term history of sinusitis, aller- gies, and asthma, with or without a history of smoking. HISTORY The patient will give a history of fever, frontal headache, severe sinus congestion, often sinus and ear pain and/or pressure, difficulty breathing, sore throat, purulent nasal dis- charge, and malaise. Inquire about the duration and severity of the symptoms. Viral ill- nesses generally run their course in 5–7 days; bacterial will worsen with time. A complaint of maxillary sinus pain without discharge is likely to be dental in origin. Examine the mouth and teeth for any obvious gum infection, or decayed or abscessed teeth. Significant periodontal infection puts the patient at risk for bacterial endocarditis, and antibiotics should be prescribed along with a prompt dental referral. PHYSICAL EXAMINATION The exam coincides with the preceding subjective information and may reveal fever; inflamed nasal mucosa; thick, colored discharge; sinus tenderness; an accompanying dull or inflamed tympanic membrane; and perhaps cervical lymphadenopathy. Simple sinusitis can be diagnosed by history and physical. Recurrent sinusitis or per- sistent sinusitis after a course of antibiotics should be further investigated with sinus x-rays or CT scanning of the sinuses. Complete blood count may confirm a bacterial cause, and a culture and sensitivity test of the nasal discharge may identify the organism responsible for chronic infections. Often, polyps are present, causing recurrent or prolonged symp- toms. Tumor may be present, requiring prompt referral to the ENT. In extreme cases, chronic sinus infection can cause bone erosion and sinus or brain abscess. Allergies Allergies are more common in the fall and spring especially in damp, warm climates where foliage is thick and present year around. In tropical climates, mold may be present in homes and buildings, thereby causing allergy symptoms. Pets, especially cats, are com- monly responsible for a patient’s allergy symptoms, especially if they are new pets. People often become desensitized to pets that are in the house for long periods, but introducing a new pet may cause or exacerbate allergy symptoms. HISTORY A thorough history is necessary to determine the cause of the allergy, if possible. PHYSICAL EXAMINATION With an allergic etiology, the patient may complain of fatigue, but will not have fever. The nasal mucosa will be boggy and pale, rather than inflamed. The nasal discharge will be clear and watery rather than purulent and yellowish green. RAST (radioallergosorbent test) studies performed on the blood will indicate the increased eosinophilia that is associated with allergies, and the use of skin testing will iden- tify specific allergens. Loss of Smell A change in olfaction can accompany any of the conditions related to nasal congestion, or it can be a more serious problem related to injury to CN I from trauma or tumor. A closed head injury along with a complaint of the loss of smell may indicate an injury in the area of CN I. Other neurological complaints will likely be present because, in a closed head injury, it would be rare to have injury only to this small portion of the brain. In a patient without a history of trauma, an isolated complaint of olfactory changes without any accompanying symptoms of cold, allergies, or sinus congestion is a red flag finding sug- gesting a brain tumor.

A prospective randomized clinical trial of the Gothenburg osseointegrated hip arthroplasty; a proximal femoral implant and a press-fit cup. Generally acrylic cements made of polymers of methylmethacrylate (MMA) are used for cement production. The scientist who first synthesized polymethylmethacry- late (PMMA) probably did not envision that this process would be a significant step in medical science. The pilots of the World War II, who carried some glassy PMMA remnants in their body as a result of shattered cockpit windshields, could not know that they already were a part of in vivo experiments for biocompatibility of polymers. Methylmethacrylate is an ester of methacrylic acid and has been intensively studied since the second quarter of the twentieth century. In 1928, a large-scale technical synthesis for MMA was established by the company Rohm¨ and Haas, and the production technique was patented by Bauer (1935; patent DRP 652821). By 1936, the company Kulzer (1936; patent DRP 737058) had found that a dough produced by mixing ground polymethylmethacrylate powder and its liquid monomer that hardens upon addition of benzoyl peroxide (BPO) and heating the mixture to 100 C in a stone mould. The first clinical use of these PMMA mixtures was an attempt to close cranial defects in monkeys in 1938. When these experiences became known, surgeons were anxious to try these materials in plastic surgery on humans. The heat curing polymer Paladon 65 was soon used for closing cranial defects in humans after producing plates in the laboratory and later fitting the hardened material on the spot (Kleinschmitt, 1941). After chemists discovered that the polymerization of MMA would occur by itself at room temperature if a coinitiator is added in addition to benzoyl peroxide, the companies Degussa and Kulzer (1943, patent DRP 973590), using tertiary aromatic amines, established a protocol for the chemical production of PMMA bone cements. These studies must be considered to be the birth of PMMA bone cements. At the end of World War II, the worldwide practical use of PMMA studies started by Otto Rohm¨ quickly spread. PMMA bone cements were developed independently in several countries. Even though their chemical bases were identical, the advantageous handling properties of MMA polymer mixtures have remained the subject of many research projects because the cements differed considerably in this respect. Kiaer first used PMMA as a pure anchoring material by fixing acrylic glass caps on the femoral head after removing the cartilage [1–3]. The fast-curing resins were also used for filling defects caused by injuries to the visceral skeleton. Judet and Judet were the first to introduce an arthroplastic surgical method. Soon, however, it became apparent that the PMMA (Plexiglas ) prosthesis could not be integrated in the body because of both biological and mechanical reasons. In 1958, Sir John Charnley was the first researcher who succeeded in anchoring femoral head prostheses in femur with in site autopolymerization of PMMA. Charnley called the material used ‘‘bone cement on acrylic basis. Today, most of the bone cements that are used in dentistry and orthopedic surgery are made of polymethylmethacrylate, and as a group they are called acrylic-based cements. These cements have been widely used for more than 30 years. In dentistry, pure PMMA is used in prosthetic applications, and the compositions that contain PMMA are used as a filler material. In orthopedic surgeries, bone cements are mainly used as a filler (for filling cavities resulting from postoperative bone loss) and for anchoring the metallic implants securely into bone medulla.

LIPEDEMA AND LIPOLYMPHEDEMA Lymphedema is described as a pathology characterized by a tumescent state of soft tissues, usually superficial (15), and is related to an accumulation of lymph with high protein con- tent due to stasis in the interstitial space. It is determined by primary and/or secondary damage of the transport vessels. In contrast, lipedema is a particular syndrome with a poorly understood etiology characterized by fat and water deposits in the subcutaneous tissue (particularly in lower limbs and gluteal muscle), and associated with lymphedema and/or lipodystrophy. Lipedema was described for the first time as an accumulation of subcutaneous fat with hard leg edema excepting the feet. In various descriptions (16), the following observa- tion has always been underlined: foot hypothermia with a localized gradient of tempera- ture. Such pathology, often superficially defined as a lymphedema or venous insufficiency or cellulite, is observed in more than 65% of women between the ages of 14 and 35 years, becoming lipodystrophic lipolymphedema after the age of 40. The common characteristics of a lipolymphedema are the absence of venous insufficiency (eventually secondary) and the close relation with the fat tissue metabolism. Lipolymphedema is a syndrome of unknown etiology, characterized with fat deposi- tion in the subcutaneous tissue and associated with orthostatic and recurrent edema in the legs and gluteal muscle that induces the impression of an increased volume in the limbs. Lipedema always begins in the legs, excluding the ankle and foot, which makes it different from lipolymphedema. It can be related to weight increase but is often independent of it. The characteristic of this extremely frequent disease is that edema always succeeds fat deposition. The latter is subsequent to endocrinometabolic disorder of the interstitial matrix and is not accompanied with obesity. The edema here is not caused by structural changes of veno-lymphatic vessels, but by the modified ratio of the distance from the adiposity and connective structure with a loss of support. It is an edema that worsens with walking and standing, in contrast to phlebo- lymphedema. Another difference from lymphedema is its softness and the possibility of its making a skin fold that is not obstructed by the viscosity. Thus it is different from lipo- lymphedema, phlebolymphedema, Barraquer–Simmond disease (characterized by upper body thinness), and Dercum syndrome; the latter, which is clinically similar, has an etiology related to toxicities of the autonomous nervous system linked to an intestinal dysbiosis. DERCUM SYNDROME The word ‘‘lipodystrophy’’ means a pathology characterized by structural and functional damage of adipose tissue. Lipodystrophy can be associated with some form of lipolymph- edema, the more typical being Dercum lipodystrophy or painful lipodystrophy. Typically painful fat nodules are often preceded by the appearance of lipedema and are often associated with asthenia, neuropsychic and 32 & BACCI adynamical troubles (depression or anxiety), and intestinal dysbiosis. Limb pain is differ- ent from the pain of lipolymphedema or from superficial hypoxia, where pain is induced by pinching the subcutaneous tissue and is associated with tissue viscosity due to intersti- tial hyperpressure of toxic lymph. Pathogenesis of the Dercum syndrome is not endocrine or metabolic (as in recurrent lipedema), but from nerve damage of the neurovegetative—either the hypothalamic or the peripheral—system. Interstitial inflammation phenomena have been demonstrated to be related to the nervous network linked to the adipose tissue in the environment of the extra- cellular matrix. In this context, bacteria from intestinal origin have also been found. This disease is certainly attributable to a suffering of interstitial mesenchyma with exaltation of the lipogenesis (slowdown of the microcirculatory flux and damage of the a-2-fibers) due to the damage to the peripheral neurovegetative regulatory system. A total or partial big leg can be observed, but there are also different kinds of big leg such as venous, post-phlebitis syndrome, posttraumatic, angiodis- plasic, lymphatic, adipose, or cellulitic big leg. The main characteristic of big leg is edema—systemic, lymphatic, venous, or interstitial edema. Considering that lymphatics run in the interstitial subcutaneous tissue, it is easy to assume that the increase of lym- phatic edema or of adipose tissue could induce a lymph slowdown.
