Most renal cell carcinomas have little infammatory response, but sometimes an intense lymphocytic or neutrophilic infltrate with natural killer cells is present, and there is an association between a strong lymphocytic infltration and worse outcome. Clear cell renal cell carcinomas most commonly metastasize haematogenously via the vena cava primarily to the lung. Papillary renal cell carcinomas are characterized by epithelial cells forming papillae and tubules.

Putative model of bladder cancer development and progression, based on to metalworking fuids is strongly im genetic findings. Continuous mucosal irritation and chronic infam mation from, for example, indwelling catheters or Schistosoma infection, can cause squamous metaplasia, dysplasia, and eventually squamous cell carcinomas of the bladder. Patients with long-term paraplegia are at markedly elevated risk for this tumour type due to chronic bladder infection. Recent genome-wide association studies have identifed multiple chro mosomal regions of which alterations are linked to the risk of developing bladder cancer [4]. Men work in the vats curing invasive papillary bladder carcinomas in hyperplasia and normal-appearing and dying leather from camels, cattle, and goats.

Intervention in re lation to proven or likely workplace exposures will prevent occupational bladder cancer, particularly in rela tion to work practices in low-income countries. For squamous cell carcinoma, avoidance of infestation with Schistosoma haematobium is an effective intervention. Screening Attempts to perform population based screening have not been suc cessful due to the low incidence of bladder cancers and the low speci fcity (and sensitivity) of tests [19,20]. Targeted therapies Urothelial carcinoma is one of the most heterogeneous cancer types. Molecular heterogeneity may com promise the effciency of targeted drugs in this malignancy. Several drugs targeting genes frequently al tered in bladder cancer have exhib ited disappointing effcacy compared with other cancer types.

The mid-tibia is the the patient suffers from multiple enchondromas most common site but any bone can be affected. In some sites, excision and reconstruction may be appropriate and in others, such as the spine or pelvis, embolization, surgery and radiotherapy may be needed. Primary malignant bone tumours Osteosarcoma this is a malignant neoplasm arising from bone cells which are undifferentiated and capable of forming bone, cartilage and collagenous tissue. It is the most commonly occurring primary tumour of bone, with an incidence of 3 per million popula tion. It usually occurs under the age of 30, in boys more than in girls, and in cylindrical bones. It almost always affects the especially at night, almost completely relieved by metaphysis.

About two-thirds of the tumours occur in cylindrical bones, but the older the patient the more likely it is that the tumour arises in a at bone because it develops from red marrow. Radiological features the most striking feature is bone destruction and often a soft-tissue swelling. Occasionally, there are onion-skin layers of new bone formation around the lesion. At diagnosis, 25% of patients will have metastases, either in the lung, other bones or bone marrow. Occasionally, the centre of the tumour may be necrotic and liqueed, resembling Figure 12. The tumours have a characteristic t11:22 transloca surface (peripheral), sometimes in an osteochon tion on cytogenetic testing.

Clinical Relevance: An assessment of clinical relevance of the studies will be performed and discussed. The assessment will be made using an adapted version of the assessment guide for clinical relevance developed by the Cochrane Back Review Group (Furlan et al. Data analysis: Descriptive data will be used to summarise the main characteristics and conclusions of the studies and these will be presented. A meta-analysis is regarded as useful tool for a systematic review as it provides a clear picture of the evidence, provides a common effect of the study data by pooling the data, and summarises the results of several studies into one single estimate of treatment effect. The meta-analysis would consider the interventions comparative to each other to consider any differences within the study results. To perform a meta-analysis of the studies for continuous data, the mean, standard deviation and sample size will be required for each trial for analysis to occur. If data from a study were inadequate for analysis, the authors were contacted to request further information (Singh et al. For continuous data outcomes, mean difference and standard deviations will be presented. Any data presented with alternative measurements will be converted into standard deviations for the pooling of the data for meta analysis. Any dichotomous data present was reported as risk ratios or odds 595 ratios and their 95% confidence intervals. Inverse variance methods (Mantel-Haenszel method) will be used for pooling of data where appropriate (Bland, 2000). A common estimate of the mean and standard deviation will be used, and data presented in other forms was converted to mean values and standard deviations for each study to provide a common study denominator. If heterogeneity fell between 50 75% then a meta-analysis will be performed using a random effects model. If heterogeneity rose above 75%, pooling of the results would not be recommended as it would be invalid to pool the results into a single summary and a narrative analysis will be provided (Singh, 2017; Gagnier et al. If any data is inadequate for analysis, the trial will be excluded from any pooling of the results and presented descriptively. A sensitivity analysis without these studies will be an efficient way to consider the influence of quality. An analysis of the stronger evidence may be useful, to see if the results differ, giving an indication of the influence of strength of research. If questionable studies exist in the review, an analysis will be performed without them to assess their influence on the results. Outcome measurements will be analysed together at their primary outcome measurement time point. Studies would be weighted to reflect their importance, the greater the sample size the greater the weighting of the trial for the meta-analysis (Bland, 2000). Dissemination strategy: It is intended for this review to be published in a high impact journal, which will access as many doctors, therapists and policy makers as possible.

Assignment generated by an independent person not responsible for determining the eligibility of the patients. This person has no information about the persons included in the trial and has no influence on the assignment sequence or on the decision about eligibility of the patient. The number of participants who were included in the study but did not complete the observation period or were not included in the analysis must be described and reasons given. Were all randomized participants analysed in the group to which they were allocated All randomized patients are reported/analyzed in the group they were allocated to by randomization for the most important moments of effect measurement (minus missing values) irrespective of non-compliance and co-interventions. This information is either obtained by comparing the protocol and the report, or in the absence of the protocol, assessing that the published report includes enough information to make this judgment. Were the groups similar at baseline regarding the most important prognostic indicators The reviewer determines if the compliance with the interventions is acceptable, based on the reported intensity, duration, number and frequency of sessions for both the index intervention and control intervention(s). For example, physiotherapy treatment is usually administered over several sessions; therefore, it is necessary to assess how many sessions each patient attended. Timing of outcome assessment should be identical for all intervention groups and for all important outcome assessments.

Patients with acute myocardial infarctions can go into a malignant arrhythmia (frequently V-Tach or V-Fib) with no warning. Resuscitation Algorithms Cardiac resuscitation algorithms have been developed by the American Heart Association, but could not be reprinted here for copyright reasons. Symptoms result due to low numbers of cells or deficient cell function (which paradoxically may occur with increased numbers of abnormal cells, such as with leukemia), or when cell numbers build up to such a point that they obstruct blood flow. Low cell numbers are caused by decreased production, or increased loss (bleeding), consumption or destruction. Plasma contains the soluble coagulation factors, immunoglobulins, electrolytes, protein and water. Evaluation of blood disorders often requires performing a spun hematocrit and a Wright (Cameco Quick Stain) stained peripheral smear (see Lab Procedures Section). Anemia Introduction: Anemia refers to an abnormally low amount of the oxygen-carrying protein hemoglobin (may also have low number or volume of red cells) in peripheral blood. It is a rough measure of the amount of oxygen-carrying protein (hemoglobin) in the sample, but is subject to many problems with technique that can lead to numbers that do not reflect the true hemoglobin content of blood. Modern Coulter Counters used in clinical labs actually measure the amount of hemoglobin, and calculate, but do not actually measure, the hematocrit. Anemia may be acute (traumatic blood loss) or chronic (due to chronic disease), and results from either increased loss/destruction of red cells or failure of the bone marrow to produce sufficient quantities of hemoglobin/red cells to make up for normal red cell loss. Normal hemoglobin levels differ among ethnic populations and between men and women, with males and whites averaging higher values. Worldwide, the most common cause of acquired anemia is iron deficiency due to chronic blood loss from hookworm and menstruation. Other important causes are lack of important nutrients (protein, Vitamin B12, Folic Acid) and suppression of the bone marrow from chronic infection or inflammation. The causes of anemia are extensive and beyond the ability of the medic to accurately diagnose in the field environment. Subjective: Symptoms Acute: Lightheadedness, pallor, shock, syncope, altered mental status. Chronic: Lethargy, fatigue and decreased energy, rapid heartbeat and shortness of breath/dyspnea with exertion. Objective: Signs Using Basic Tools: Acute: shock, hypotension, weak pulse, syncope, altered mental status. Increased eosinophils suggest either infection (parasites, especially visceral larval migrans, or chlamydia), hypersensitivity or allergic reactions. Increased basophils are so unusual as to suggest a problem with the stain or staining procedure. Unusual hemoglobins or hemoglobin levels may be common within certain ethnic groups. Iron supplementation is appropriate only for menstruating females and patients whose stool is positive for occult blood, pending further evaluation. Iron supplementation is not otherwise appropriate without laboratory determination of iron deficiency. Blood replacement in the face of rapid loss is addressed in Procedure: Field Transfusion*. Liberal use of medications for pain (Selection of medications is determined by the severity of the pain. Non-steroidal anti-inflammatory drugs like ibuprofen, acetaminophen with codeine, or intravenous morphine are appropriate for mild, moderate and severe pain, respectively, and should be continued until pain levels decrease. Follow-up Actions Evacuation/Consultation Criteria: Evacuate patients with acute anemia and acute sickle crisis after initial stabilization. This section focuses on the relatively mild, viral, acute respiratory tract infections (contrast with Acute Respiratory Distress Syndrome Section later in this chapter), typically called colds. Acute local infections generally occur at the site of viral infection the nose and throat. Patients generally continue functioning with a cold virus, but with u their activity is more seriously curtailed. Elderly patients, infants, expectant mothers (3rd trimester) the immunosuppressed and patients with chronic heart and lung diseases will have more frequent life-threatening complications, such as pneumonia. Subjective: Symptoms General: Malaise, fever, nasal congestion, clear secretions, sneezing, scratchy or sore throat, cough, hoarseness, and headache Focused History: Quality: Is your cough productive Allergic rhinitis seasonal history of itching in nose, roof of mouth, throat, and eyes; increased tearing, sneezing and watery discharge; sore throat due to postnasal drip (granular appearance to posterior pharynx); nasal membranes swollen and red. Irritant rhinitis non-seasonal history of exposure to irritant, rhinorrhea without ocular symptoms or sore throat. Mononucleosis positive Monospot; longer illness; higher fever, chills, malaise, sore throat, and swollen cervical lymph nodes. Sinusitis tender sinuses; red, swollen nasal membranes; green or yellow discharge from nose and throat; can follow a cold. Mumps seen typically in children but can attack non-immune adults; swollen salivary glands. Pertussis characteristic whooping cough; seen typically in children but can attack non-immune adults. Diphtheria seen typically in children but can attack non-immune adults; gray membrane maybe seen on pharynx. Adenovirus fever, pharyngitis, and/or conjunctivitis; usually in epidemics in non-immune recruits or displaced persons Strep Pharyngitis palatal petechiae, red beefy uvula, and scarlatiniform rashes are typical for Group A streptococcal pharyngitis. Gonococcal Pharyngitis often asymptomatic, but may have sore red throat, painful swallowing and history of exposure Plan: Treatment 1. See appropriate sections for treatment of pneumonia, infectious mononucleosis, sinusitis and other illnesses that present similarly to cold/flu. Antibiotics: Only indicated in patients that may have or are at high risk for a secondary bacterial infection (see pneumonia). Allergic rhinitis: Diphenhydramine Adults and children over 12: 25-50 mg po tid/qid; children under 12: 5 mg/kg/day po in divided doses qid. Irritant rhinitis: Use saline nose drops to lavage nasal mucosa, followed by pseudoephedrine 30-60mg po q4-6h to decrease mucus membrane swelling. Codeine q hs can be used for severe cough and will cause drowsiness (use no more than 3 nights). Influenza: Give Relenza (zanamivir) for patients ages 7 years and older within two days of the onset of symptoms. The drug is less effective in patients whose symptoms are not severe and do not include 4-11 4-12 fever. If patients develop wheezing, discontinue the drug and be prepared to treat symptoms (see Respiratory: Asthma). Amantadine or rimantadine shorten duration of symptoms by 50% and are recommended for patients at high risk for complications from infection. Patient Education General: Infections can spread via airborne droplets (cough, sneeze) and contact (contaminated hands, lips and objects). The usual course of a cold is 6-10 days, and about half that length for uncomplicated influenza. The vaccine cannot cause influenza, but some side effects (myalgia, headache) may mimic mild influenza or cold symptoms. Follow-up Actions Return Evaluation: Evaluate for alternative diagnoses and complications, including secondary bacterial infection, if still symptomatic after 72 hours of treatment (particularly if in high-risk group). Evacuation/Consultation criteria: Evacuation not usually necessary, except for moderate to severe influ enza. Palpation: Warm over dull-sounding area empyema Auscultation: Rales indicates an infiltrate; rhonchi indicate airway secretions; dullness may indicate lobar consolidation, collapsed lung, or a pleural effusion. Atelectasis can resemble pneumonia but is caused by a mechanical airway obstruction, chest wall abnormality or a loss of normal lung space. The treatment for atelectasis focuses on opening up the alveoli with aerosol bronchodilators, cough induction, and antibiotics if infection is present. Hospitalized Patients on Intravenous Antibiotics: Start treatment as soon as possible. Change to single agent oral therapy 24 hours after the patient clinically improves. Prevention: Vaccinate all personnel for inuenza and adenovirus, and vaccinate those without spleens for pneumococcus and haemophilus. No Improvement/Deterioration: Return if symptoms do not resolve or improve in 48 hours. If poor response or late deterioration (5-10% of patients), suspect inadequate antibiotic dosing. If available, do follow-up chest x-ray in 6-8 weeks to evaluate resolution of inltrate. Consult pulmonologist, internist or infectious disease specialist as needed and for pleural effusion (see Pleural Effusion section), empyema and hemoptysis (possible occult malignancy). If the uid accumulation is large (>1/3 of the hemithorax or over 1-2 liters), it can interfere with the mechanical ability to breathe. The two major types are transudative effusions, which are passive uid accumulations, and exudative effusions due to irritation and inammation. Transudative effusions are usually bilateral, slightly greater on the right side and are usually caused by heart failure, low albumen in circulation and rapid loss of albumen in the urine (nephrotic syndrome). Exudative effusions are caused by inammatory involvement (including infection) of the overlying visceral pleura, which often results in acute pleurisy and the leakage of serous uid into the pleural space. A large number of neutrophils containing bacteria indicate an early empyema (see Empyema) while large cells of abnormal shape may indicate cancer. Atypical lymphocytes can occur with viral infections such as inuenza or Coxsackie virus. Subjective: Symptoms Stabbing chest pain with breathing or cough (pleuritic pain), or chest pressure or tightness that changes with position (mimicking angina). Auscultation: Chest: Clear, although occasionally a pleural friction rub may be heard. Heart: Extra sounds (murmurs, rubs and gallops) may indicate signs of cardiac failure. Assessment: Differential Diagnosis Transudative effusion congestive heart failure, liver failure (any cause), nephrotic syndrome (any cause). If a transudative effusion is suspected, give a trial of Lasix 20-60 mg po qd-bid 2. Perform thoracentesis (see following section) to improve breathing, if Lasix ineffective or in the face of unimproving pneumonia. Try not to remove more than 1000-1500 cc of fluid in the first 24 hours (can repeat procedures). Removing too much fluid can cause rapid fluid shifts in the lung tissue, which worsens hypoxemia (newly expanded lung is poorly perfused) and causes hypotension. Diet: High protein diet unless liver failure is present, then diet must be modied to avoid hepatic encephalopa thy Follow-up Actions Return Evaluation: Refer patients that do not improve for specialty care and additional special studies. Evacuation/Consultation Criteria: Evacuate unstable patients, or those who require on-going thoracente ses. Risks: Thoracentesis is a relatively safe procedure; however, some relative contraindications include history of coagulopathy (increase risk of bleeding), pleural effusion of insufcient volume (little uid layering on lateral decubitus chest lm), and underlying severe respiratory disease. Complications of thoracentesis include pneumothorax, bleeding, infection, puncture of abdominal organs, and pulmonary edema of the reinated lung. Thoracentesis can cause a pneumothorax in two ways: by introducing air through the back of the syringe or needle hub into the pleural space (it does not progress to complete pneumothorax and does not require treatment), or by an accidental puncture of the lung. More severe leaks are caused by coughing or needle movement, which causes a larger tear in the lining of the lung. The posterior approach is most common because the interspaces between ribs are wider in the back. The ideal location is the 7th or 8th interspace posteriorly, midway between the posterior axillary line and midline. Tap with a finger and listen with or without a stethoscope to identify where the percussion becomes dull (height of pleural fluid accumulation). Mark this location by pressing the tip of an ink pen (point retracted) into the skin below where dullness begins and inferior to any underlying rib (avoid the neurovascular bundle immediately below the inferior rib margin). Gently apply pressure for 30 seconds to leave a small red circle that will last during the procedure. Loculated or small effusions may not always be accessible with this approach and should be evacuated if possible for advanced care. Have the patient straddle a chair backwards; resting their arms on the back of the chair. Aspirate to ensure no blood return before injecting lidocaine, then advance slightly and repeat. Aim the needle towards the upper margin of the rib and anesthetize the top of the rib, then the parietal pleura. Advance the needle gently and carefully while keeping suction, then stop and inject lidocaine, and advance again. The clamp may be used to stabilize the needle at the skin to prevent accidental additional penetration of the needle down to the lung. Be sure to describe the site and approach used, the appearance of the fluid and how much fluid was removed. Have the patient remain in bed for at least 2 hours after the procedure, avoid coughing or lifting objects for 24 hours, and inform you immediately if they cough up blood, experience shortness of breath, dizziness, a tight feeling in the chest, or any other problems. Send sample of fluid for the most important tests first, which are gram stain and differential count of inflammatory cells in a field setting. What Not To Do: Try not to move the plunger end of the syringe laterally during the procedure. This swings the needle around inside the patient, tearing the pleura and causing a large pneumothorax. It can also arise from inoculation of the pleural cavity after penetrating chest trauma, esophageal trauma, thoracentesis or chest tube placement. Subjective: Symptoms Gray skin, sweating, chills, malaise, fever, chest pain, cough, emaciation, and poor appetite. Patient Education Activity: Restrict activity Diet: High calorie with adequate protein to replace body stores 4-17 4-18 Follow-up Actions Return Evaluation: Refer patients that do not improve for specialty care and additional special studies. It is different from inammatory disease of the airways (asthma) in that it diffusely affects the lungs and symptomatically presents as a sub-acute, progressive or recurrent pneumonia.
