We do not want to teach the only and best solution, but we would like to give a useful tool in the hand of a surgeon who wants to have an “up to date” overview of a certain topic. We are aware that dealing with one topic per year will be a long process to cover the whole field of hand surgery. The enormous amount of data available and the short turnover of validity make this task even more difficult. In spite of these obstacles we think that we should start with this issue and life will show the value of it. We already have the fantastic contribution of a large number of famous hand surgeons. You may be satisfied with it or not but the most important is to provide feedback on it. Remember that the whole variety of our activities, especially the educational ones have one common goal: to improve the outcome of our patients. As a matter of Pfact, going through the list of the brilliant personalities, who will be remembered for the permanent sign they left in the development of basic science and therapeutic surgical strategies in nerve injuries and disorders, there is no doubt that the majority of them rightfully belong to the Hand Surgery Community. The disciplines, which were interested in joining the Committee by their rep resentatives and in which Hand Surgery is closely linked to, were Orthopaedic and Tra uma Surgery, Plastic Surgery, General Surgery, and Paediatric Surgery. At a political level European Hand Surgeons are represented through the European Board of Hand Surgery. It is interesting to quote here the first paragraph of the White Book where the areas of interest of Hand Surgery are reported and the relevance of basic science and surgery in peripheral nerve injuries and disorders is clearly highlighted. Hand Surgery is defined as a competence whose aim is to restore the function of the hand, which should be regarded as the key organ of prehension and sensibility. In this context, hand surgeons are also involved with complex problems of the whole up per extremity, including lesions of the peripheral nerves and the brachial plexus. Hand surgeons are also involved in the restoration of prehension in cases of tetraplegia and spasticity. Because of their special expertise, hand surgeons are also frequently involved in the repair of lesions in nerves of the lower extremity. The scope of Hand Surgery is broad and requires a wide range of diverse surgical skills necessary to diagnose and treat, conservatively or surgically, injuries and disorders of the hand and pertinent upper extremity as well as peripheral nerves. The hand surge on must be skilled in microsurgery as well as in techniques of Orthopaedic and Plastic Surgery as applied to the complex and delicate anatomy of the hand and upper extre mity. A close cooperation with other specialists is required, including orthopaedic and trauma surgeons, plastic surgeons, radiologists, paediatric surgeons, rheumatologists, anaesthetists, specialized physiotherapists, occupational therapists and other paramedics for rehabilitation, orthotics and prosthetics. The treatment of a lesion of the hand/upper extremity in the earliest phase by a surgeon trained in Hand Surgery offers the patient the best chances of early and best re covery, and also reduces the costs related to the disability and time-off work for society. This is true for hand trauma in general and particularly for peripheral nerve injuries and 4 disorders, where a timely and precise treatment provides the best functional expectati ons. With its clear editorial plan, and thanks to the recognized expertise of its contribu tors, this Instructional Course Book is certainly a most valuable tool aiming to foster education and learning – not only for the young surgeon – in one of the fascinating chapters concerning the hand surgeon’s professional field. With the growing number of hand surgeons, it testifies for its wide recognition and acceptance. Starting from this year, the book has been planned and edited as teaching book for younger surgeons (but not only! The contributi ons reflect the state of the art of each field and offer an in-depth view accompanied by a selection of multiple choice questions. As Chairman of the Examination Committee I’m very grateful to the Editor of the book, to the Organizers and to all who participated to the planning, writing and editing of this book for its new features. In most countries, Hand Surgery re mains within the umbrella of orthopaedic surgery, plastic surgery or both. There is probably overall, a trend in Europe towards Hand Surgery separating from the parent speciality. Britain) Hand Surgery is a separate speciality in some centres and part of Plastic Surgery or Orthopaedic Surgery in others. In contrast to this trend, in 2006 Hand Surgery in Sweden had to retreat from an independent basic specialty into a branch of orthopaedics, but beginnining from 2014 Hand Surgery will again be an independent basic speciality. However, even within Hand Surgery, there are sub-specialities, such as brachial plexus, congenital differences, micro-vascular surgery, tetraplegia and complex wrist reconstruction. Service provision and training for these rare topics differ even more broadly across Europe.

Injury film showing transverse/short oblique fractures of the index, long, and ring finger metacarpal shafts. Injury film showing a comminuted fracture of the metacarpals of the ring and little fingers (also with involvement of the carpus) as the result of a handgun injury. A comminuted fracture may require transarticular K-wires or exter nal fixation to maintain length through indi rect reduction. Complications—Complications include mal union, nonunion, and posttraumatic arthritis. Accurate reduction of the articular surface Lateral Frontal Lateral Frontal minimizes posttraumatic arthritis. Physeal Fractures in Children—More than 34% of hand fractures in children involve the epiphyseal growth plate. Common locations for such fractures are the base of the proximal phalanx, the base of the distal phalanx, and the base of the index, long, and ring finger metacarpals. Classification—The Salter-Harris classification Transverse Oblique Comminuted is used for physeal injuries of the hand. This in jury requires accurate reduction of the joint surface to avoid posttraumatic arthritis. These fractures are five annular (A1, A2, A3, A4, A5) and three cruciate are thought to be the result of a severe axial (C1, C2, C3) pulleys. Most blood ves sels to the flexor tendons are located in the epitenon, which is continuous with the endo tenon surrounding individual bundles of colla gen within the tendon. In the distal palm and digits, the flexor tendons are enclosed within a synovial sheath. The visceral synovial layer covers the flexor tendons, and a parietal layer is con tinuous with the annular and cruciate pulleys. The annular pulleys provide mechanical stability, and the cruciate pulleys permit flexibility at the joints (Fig. The thumb has an A1, an oblique, are contained within one tight fibroosse and an A2 pulley.

Of the non-evidence-based clinical quality indicators, 5 were found to be highly relevant. Perinatal care Of the 22 merged evidence-based clinical quality indicators, one was rephrased by the experts in obstetrics. Above this, seven indicators were rejected because of their low relevance for clinical practice. Of the non-evidence-based clinical quality indicators, 21 were found to be highly relevant, which were merged into 3 indicators. Elderly care Three of the 42 merged evidence-based clinical quality indicators were rephrased by the clinical experts in geriatric medicine. Of the non-evidence-based clinical quality indicators, 47 were assessed as relevant. Total hip prosthesis Two of the 7 merged evidence-based clinical quality indicators were reformulated by the expert group of orthopedists. No additional non-evidence-based clinical quality indicators of high relevance were identified. On the other hand, a Medline search did not identify a lot of additional indicators. Above this, 21 evidence based clinical quality indicators were rejected and some non-evidence-based clinical quality indicators were added because of their high relevance. This explorative study was therefore run on the 2003 Minimal Clinical database and on the 2003 Financial administrative database. These administrative databases are already coupled and readily available on request. Hence, the explorative study of the four sets of indicators was based on data extracted from these sources, as they summarize the medical record. This had the advantage that data extraction requests were straightforward and did not imply back and-forth information retrievals, like gathering all the stays from a selected patient. Referrals after an initial hospital stay leading to subsequent admissions were in consequence deliberately lost, although we acknowledge the fact that referral (and readmission) can be important parameters for quality. The codes used for the extraction from the administrative databases were validated by the Technical Cell (“Cellule Technique/Technische Cel”). Studies on a similar topic were used as a 140-142 support to select the appropriate codes in the administrative databases. Subarachnoid, intracerebral and other intracranial hemorrhages (430, 431 and 432), transient ischemic attack (435) and not acute ischemic event (438) were not selected as principal diagnosis. Stroke is indeed a relatively well known and then well coded condition and the aim was to select only the patients to whom the clinical quality indicators applied. First, the Public Service of Health Manual advises to code 436 into the clinical data when stroke is not further specified (precerebral or cerebral location) in the medical record. Second, this code was used by in methodologies described in the 140-142 literature. As another example, a pregnant woman admitted for a stroke occurring during pregnancy will receive as principal diagnosis 674. But those complicated cases of deliveries that require atypical care are marginal. The link between the mother and the newborn can be theoretically retrieved from the administrative clinical records. This narrow restriction would probably let some vulnerable elders aside from the selection. However, this selection was deliberately more specific than sensitive to be sure that the clinical quality indicators were only measured for the care of vulnerable elderly. All stays of patients aged 65 or above, admitted in a home for the aged or in a psychiatric institution immediately before or after their hospitalization, were extracted. Some of them were a priori non measurable considering the information that had to be collected. However, during the discussion rounds with the external experts, 11 evidence-based clinical quality indicators were rephrased in order to improve their feasibility (see chapter 5. In total, 67 clinical quality indicators were screened for their a priori feasibility (see paragraph 5. Feasible evidence-based and non-evidence-based clinical quality indicators (see appendix 2 for detailed information). The involvement and choice of the caregiver and patient were indeed not measurable.

Reporting Outlined below are examples of sample reports for various common clinical scenarios: - Palpable mass (a) Clinical details Mobile mass left posterior triangle. The palpable mass in the left mid posterior triangle is identified as a fusiform shaped lymph node measured at 2. It displays an echogenic hilus, the appearances are typical of a benign lymph node – no sinister features identified. The remainder of the left neck looked unremarkable, I have not examined the right side of the neck. There are signs of coagulation necrosis and possible extra capsular spread – consistent with a metastatic lymph node from a potential squamous cell carcinoma primary. Nodes identified in the right submandibular region and lower deep cervical chain and right posterior triangle but these all appear benign. Some incidental benign nodules are seen within the left lobe of thyroid but no signs of anything sinister. I have asked the patient to contact your surgery in one weeks time to make an appointment with you to discuss the results. Apart from some benign looking intra parotid nodes, the remainder of the right parotid looks normal. A contralateral tumour is identified in the inferior aspect of the left superficial parotid. Remainder of the left parotid looks unremarkable, no significant left cervical lymphadenopathy seen. Ultrasound cervical region Multiple small iso-echoic nodules are identified in both lobes of the thyroid, several of the nodules exhibit cystic change with ring down signs indicative of colloid. Thyroid is mildly increased in size, no significant associated lymphadenopathy and no retro-sternal extension present. No lymph nodes Ultrasound thyroid Within the mid pole region of the left lobe of the thyroid there is a 2. Several smaller nodules are seen in the right lobe but these display typical benign characteristics. The findings are highly suggestive of a small papillary carcinoma of the left lobe of the thyroid with a probable left mid deep cervical lymph node metastasis. Bilateral metastases Ultrasound cervical region the tongue primary tumour can be identified on ultrasound, within the posterior left tongue. There are multiple rounded lymph nodes with signs of coagulation necrosis in the left upper cervical region, largest measured at 2. There are small benign looking nodes in the superior left submandibular region and within the lower left jugular (deep cervical) chain and posterior triangle. Assessment of the right neck is unremarkable, benign nodes seen in the right upper deep cervical chain but no signs of contralateral lymph node metastases. Left-sided polysplenia + situs solitus or ambiguous is diagnostic of biliary atresia. If a normal scan is found in an infant with conjugated hyperbilirubinaemia, then it is mandatory to refer the patient to a paediatric liver specialist as soon as possible so that biliary atresia may be confirmed or excluded and managed accordingly. Glossary of terms used in paediatric liver ultrasound reports Focal lesions: benign Abscess: an early abscess may be difficult to identify and the only clue may be posterior acoustic enhancement and clinical symptoms. The lesion then becomes echo-poor and more clearly defined and may possibly contain gas if the infection is caused by a gas-forming organism. Adenoma: uncommon in children although they are associated with glycogen storage disorders. Calcification: this may be either incidental small foci that are a sequel of an intra-uterine event such as infection or it may be part of a larger solid lesion. Haemangioma: an incidental finding of a small lesion of increased reflectivity in either a subcapsular position or adjacent to a blood vessel. There may be multiple small focal lesions of reduced reflectivity throughout the liver or one large vascular lesion. The hepatic artery is large with high velocity intrahepatic flow and the diameter of the abdominal aorta decreases below the level of the celiac axis.

After the initial compression, the delivery of a small amount of heat welds the vessel walls together. The laser light can be focused on a bleeding point to induce rapid tissue heating. Both lasers have been used in the endoscopic treatment of ulcer hemorrhage (Figure 23). Clinical trials of ulcer hemorrhage have confirmed that photocoagulation provides effective hemostasis for active and non-bleeding visible vessels. Important considerations that limit emergency laser hemostasis include portability and cost. Additionally, the need for specific expertise by the endoscopist and technician, special electrical outlets, eye protection, and technical considerations (difficulty in aiming the laser beam) are further limiting factors in emergency situations. Electrocoagulation Heat generated from high-frequency electrical current is capable of coagulating or cutting tissue. Monopolar and multipolar endoscopic electrodes are currently available, and both must contact the mucosal surface to be effective. Current is concentrated much closer to the tip than in the monopolar probe, resulting in less depth of tissue injury and lower perforation potential. The cylinder transfers heat from its end or sides to tissue when positioned perpendicularly or tangentially. This probe may be passed through the biopsy channels of larger endoscopes and positioned on bleeding lesions to produce tamponade and heat (Figure 25). Studies have shown the heater probe to be safe and effective for the treatment of ulcer bleeding or non-bleeding visible vessels, achieving hemostasis and significantly improving clinical outcomes. These devices are less expensive, portable, easy to use, have target irrigation, and allow tamponade and tangential coagulation. Injection Therapy Injection therapy for upper gastrointestinal bleeding is inexpensive, simple and widely used. A sclerotherapy catheter with a small retractable needle is passed through the biopsy channel of the endoscope. Non-bleeding visible vessels are treated by the injection of a solution at three or four surrounding sites about 1-3 mm from the vessel. In cases of bleeding vessels, injections are made around the bleeding point until hemostasis is achieved. Several different sclerosant agents have been used alone or in combination to achieve endoscopic hemostasis. Adrenaline; hypertonic saline and adrenaline combined; adrenaline and polidocanol; pure ethanol; or combinations of dextrose, thrombin, and sodium morrhuate have shown improvement in rebleeding, the need for urgent surgery, and mortality. Combined injection and thermal treatment have theoretical advantages in the treatment of bleeding ulcers. Injection with epinephrine produces vasoconstriction and activates platelet coagulation, reducing blood flow and potentiating thermal therapy, which produces coaptive coagulation. Recent studies have shown combination therapy (epinephrine injection and heater probe) benefited patients with spurting bleeding, but not those with oozing bleeding. Mechanical Therapy Endoscopic hemoclips have recently been developed and made their way to the scene of endoscopic therapy for peptic ulcer disease. These devices are small 3-4 mm titanium clips that can be opened and closed while being operated through the working channel of the endoscope. When fully deployed, they remain fastened to the vessel after the endoscope has been removed from the patient. Emerging studies have shown that hemoclips are an effective and safe method for treating certain forms of peptic ulcer desease and should be used in the appropriate setting. Radiological Therapy Angiography is a useful diagnostic and therapeutic modality in treatment of bleeding gastric and duodenal ulcers. Angiography can identify the site of bleeding in instances where endoscopy has failed to be diagnostic. Effective in 50% of cases, vasopressin intra-arterial infusion causes vasoconstriction that results in the cessation of ulcer hemorrhage. Embolic material such as an absorbable gelatin sponge, tissue adhesives, or other occlusion devices (such as microcoils) (Figure 27) can be inserted through a catheter into the area of bleeding.

See the American Society of Clinical Oncology guidelines for the following indications: increasing chemo therapy dosage intensity, using as adjuncts to progenitor cell transplantation, administering to patients with myeloid malignancies, and using in pediatric populations. The patient should begin prophylactic treatment with either a quinolone antibiotic or trimethoprim/ sulfamethoxazole. The patient, who is neutropenic, should be monitored closely for signs and symptoms of infection. Megakaryocytes (platelets) = a normal range of 140,000–440,000 cells/mm3 with a circulating life span of 5–10 days. Thrombocytopenia is defned as a platelet count less than 100,000 cells/mm3; however, the risk of bleeding is not substantially elevated until the platelet count is 20,000 cells/mm3 or less. Many institutions do not transfuse platelets until the patient becomes symptomatic (ecchymosis, petechiae, hemoptysis, or hematemesis). Other institutions transfuse when the platelet count is 10,000 cells/mm3 or less, even in the absence of bleeding. Signs and symptoms of anemia include weakness and fatigue, irritability, tachycardia and palpitations, shortness of breath, chest pain, pale appearance, dizziness, decreased mental acuity, ecchymoses, blood in urine or stool, and hematomas. There are several types of anemia, including microcytic (iron defciency anemia), macrocytic/ megaloblastic anemia (vitamin B12 defciency, folic acid defciency), anemia of chronic disease (includ ing chemotherapy-induced anemia), anemia of critical illness, hemolytic anemias, and drug-induced anemias. Treatment includes oral iron supplementation: 200 mg elemental iron divided twice daily or three times daily for 3–6 months. Iron products should be taken with food to avoid gastrointestinal discomfort (but absorption will be decreased). Vitamin C may increase the absorption of iron and is often used to increase the effcacy of iron products. Parental Iron Products Iron Dextran Sodium Ferric Iron Sucrose Ferumoxytol Gluconate Elemental iron 50 mg/mL 62. Causes of B 12 12 defciency include inadequate intake, malabsorption, and inadequate utilization. Folate defciency is caused by inadequate intake, decreased absorption, hyperutilization, and inadequate utilization. Hypersegmented polymorphonuclear leukocytes may also be present on the peripheral smear. In B12 defciency, patients may experience neurological changes, glossitis, weakness, loss of appetite, and possibly thrombocytopenia, leucopenia, and pancytopenia. Folate defciency also presents with glossitis and other central nervous system symptoms including weakness, forgetfulness, headache, syncope, and loss of appetite. Treatment options for vitamin B12 defciency include oral replacement daily or intramuscular replace ment weekly for 1 month, then monthly. Pregnant women should take supplements to prevent neural tube defects in the fetus. Anemia of Chronic Disease (Specifcally Chemotherapy-Induced Anemia): Causes of Anemia and Fatigue in Adult Patients with Cancer 1. Decreased or inappropriate endogenous erythropoietin production or decreased responsiveness to endogenous erythropoietin 4. Although anemia can certainly contribute to or worsen fatigue, there are probably other (perhaps many) mechanisms of fatigue. Fatigue can be assessed with a numeric rating scale, 0 = no fatigue and 10 = worst fatigue imaginable, or with any of several questionnaires. Darbepoetin has additional carboxy chains, resulting in a longer half-life compared with epoetin. It is important to distinguish between the use of these agents for chemotherapy-associated anemia and cancer-associated anemia. Adverse events: Hypertension and seizures, venous thromboembolism, and pure red cell aplasia (rare). The use of these agents requires baseline and follow-up monitoring to determine whether agents need titration or discontinuation. Dosing of Erythropoiesis-Stimulating Agents Agent Starting Dosage Dosage Increase Dosing Parameters Erythropoietin 150 units/kg 300 units/kg Hgb must be < 10 to initiate and continue therapy (Procrit, Epogen) subcutaneously subcutaneously Evaluate after 4 wk and increase dosage if rise is 3 times/wk 3 times/wk < 1 g/dL 40,000 units 60,000 units Decrease by ~25% if rapid rise in Hgb subcutaneously subcutaneously Discontinue therapy if no response after 8 wk weekly weekly Darbepoetin 2.

Chest x-ray patterns include multiple nodules (which frequently cavitate), infiltrates, and solitary nodules. However, treatment with cyclophosphamide results in complete remission in over 90% of patients. Prednisone may be started at 1 mg/kg daily, maintained for 1 month, tapered to alternate-day therapy, and then gradually discontinued, depending on the patient’s response. Cyclophosphamide should be started at 2 mg/kg orally and continued for at least a year. If, at the end of the year, clinical remission has been obtained, the cyclophosphamide may be tapered and discontinued. The patient’s hematologic parameters should be closely monitored for cyclophosphamide toxicity. In a recent study of patients who had a partial or complete remission after cyclophosphamide/prednisolone induction therapy, leflunomide together with low-dose prednisone was used for maintenance therapy. Histopathology Necrotizing granulomatous Linear deposition of IgG along vasculitis of upper/lower basement membrane of lung respiratory tract. Primary Chronic sinusitis/rhinitis, fever, Hemoptysis, dyspnea, easy symptoms weight loss, cough, chest pain, fatigability. This type of hypersensitivity vasculitis principally involves the skin, joints, intestine, and kidney. The disease is usually self-limited, although chronic renal failure may rarely occur. A history of recent infection, usually of the upper respiratory tract, is often reported. Serum IgA levels may be elevated and IgA deposition can be demonstrated in the affected tissues. Intimal proliferation of the small and medium-sized pulmonary arteries is prominent. In a patient who complains of fatigue with hair-combing and stair-climbing, what are the most likely diagnoses? Diseases characterized by proximal muscle weakness, such as myasthenia gravis, Eaton-Lambert syndrome (myasthenic syndrome), polymyositis, dermatomyositis, and polymyalgia rheumatica. The biologic effects of glucocorticoids are not synchronized with blood levels of the drug; effects do not start until a minimum of 4–6 hr after administration. The kinetics of a hypersensitivity response is an important diagnostic clue to the underlying mechanism. Classification of collagen vascular diseases is based on clinical criteria, with laboratory testing playing a useful but subsidiary role. If the patient’s tears wet only 10 mm of the filter paper in 5 minutes, tear production is poor and the test is considered positive. Other ophthalmologic tests include rose Bengal staining of the conjunctivae and/or the finding of keratitis on slit lamp examination. Symptoms resolve shortly after discontinuation of the drug, although laboratory abnormalities may persist for months or years. Vaccinia (smallpox) is no longer given, and oral live polio vaccine is only used in special circumstances. Conditions in which live vaccination of patients should be avoided are listed in Table 11-14. The risks of infection and detrimental effects without the vaccine are greater than the risks of receiving immunization. An immunologic reaction of the skin and mucous membranes to a variety of antigenic stimuli. The lesions may be localized or widespread and consist of bullae, erythematous plaques, and epidermal cell necrosis. The lesions are usually bilaterally and symmetrically distributed on the extensor surfaces of the limbs, on the dorsal and volar aspects of the hands and feet, and on the trunk. They appear as a central vesicle or dark purple papule, surrounded by a round, pale zone that is in turn surrounded by a round area of erythema.
