Reinke's edema is often diagnosed by an Ear, Nose & Throat (ENT) specialist or an Otolaryngologist by examination of the vocal cords. First, the doctor will review the patient's medical history and symptoms, such as hoarseness, dysphonia, and reduced vocal range. There is no familial or hereditary link to Reinke's edema. Because Reinke's edema is linked heavily to smoking, the doctor will need to know if the patient is a habitual smoker. Once the patient's history is reviewed, the vocal cords will be visualized using laryngoscopy, a technique in which a tube with a camera (endoscope) is passed through the nose and down the larynx. Laryngoscopes can be rigid or flexible. Flexible laryngoscopes, such as fiber laryngoscopes, allow the patient to produce sound as the tube is placed, and therefore allows the doctor to visualize movement of the vocal cord.

Based on the results of the laryngoscopy, Reinke's edema can be classified using a standardized system set in place by Yonekawa. This system characterizes the disease based disease .

Yonekawa Classification:

- Grade I – Lesions contact the anterior third of the vocal fold

- Grade II – Lesions contact the anterior two-thirds of the vocal fold

- Grade III – Lesions contact the entirety of the vocal fold

If further evaluation is needed, stroboscopy is used to examine mucosal waves of the vocal cords. Mucosal waves describe the waves produced by vibration of the vocal cords during speech. Stroboscopes produce flashes of light that are timed to the patient's vocal frequency. Every time the light is flashed, it will create a still frame image of the vocal cords at that particular moment in time. These are combined to produce an image of the wave. In the case of Reinke's edema, structural changes to the vocal cords will result in abnormal wave patterns.

The first step in treating Reinke’s edema is to eliminate or control those risk factors that are causing the disease. This includes the cessation of smoking, the control of gastric reflux using antacids and/or Proton Pump Inhibitors (PPIs), and the discontinuation of activities that cause vocal distress. Those experiencing a hoarseness of the voice may choose to undergo voice therapy to improve the voice’s quality and range. Most cases of Reinke’s edema are caused by the long term usage of cigarettes. In this case, it is important to make lifestyle changes to stop smoking. While this will not resolve or improve the edema, the cessation of smoking will halt the disease's progression.

If the elimination of risk factors is not sufficient to improve the patient’s symptoms, surgery may be required. The most common type of surgery performed today for Reinke's edema is called surgical microlaryngoscopy. Most procedures follow the microflap technique set in place by Hirano. During surgery, an incision is made into the vocal cord using either microscissors or a CO laser. A flap of mucosa is lifted and the affected tissue is removed using suction or a microdebrider. The flap is then re-draped and trimmed to the appropriate size.

Most cases of Reinke’s Edema are bilateral - effecting both vocal cords - rather than unilateral. In the case of bilateral edema, the surgeon must choose whether to operate each side of the vocal cord in two separate surgeries or to operate both sides in a single surgery. The complication associated with removing tissue from both sides in a single surgery is that the raw, cut ends of the vocal cords may form an anterior glottis web, in which the two sides grow together in a continuous sheet. Other complications of surgery include tissue scarring due to damage to the vocal ligament during the incision and vocal cord stiffening due to over-suctioning of the superficial lamina propria (Reinke’s space).

While surgical microlarynscopy has its associated risks, if left untreated, Reinke’s edema can lead to a variety of long-term complications. Besides dysphonia (impaired speech), the most serious of these complications is airway obstruction due to severe inflammation of the vocal cords. The risk of complications has decreased drastically with the creation of new tools, such as the CO laser for surgical microlaryngoscopy. Before the Hirano microflap method was developed in 1895, vocal stripping was the most common procedure used to correct Reinke's Edema. Vocal stripping was often performed without magnification and with a monocular laryngoscope, instead of a binocular scope. This led to major complications such as vocal ligament scarring.

Women are more likely than men to undergo surgery due to a greater change in vocal pitch and quality. Surgery is capable of restoring the voice, with the condition that smoking is not resumed after surgery. Post-operative voice therapy is also advised to restore the voice's strength. Reinke's edema is not a fatal pathology unless the tissue becomes precancerous.

The main techniques of diagnosing SVCS are with chest X-rays (CXR), CT scans, transbronchial needle aspiration at bronchoscopy and mediastinoscopy. CXRs provide the ability to show mediastinal widening and may show the presenting primary cause of SVCS. CT scans should be contrast enhanced and be taken on the neck, chest, lower abdomen and pelvis. They may also show the underlying cause and the extent to which the disease has progressed.

There are different approaches to non-invasive intracranial pressure measurement, which include ultrasound "time-of-flight" techniques, transcranial Doppler, methods based on acoustic properties of the cranial bones, EEG, MRI, tympanic membrane displacement, oto-acoustic emission, ophthalmodynamometry, ultrasound measurements of optic nerve sheath diameter, and Two-Depth Transorbital Doppler. Most of the approaches are "correlation based". Such approaches can not measure an absolute ICP value in mmHg or other pressure units because of the need for individual patient specific calibration. Calibration needs non-invasive "gold standard" ICP meter which does not exists.

Non-invasive absolute intracranial pressure value meter, based on ultrasonic Two-Depth Transorbital Doppler technology, has been shown to be accurate and precise in clinical settings and prospective clinical studies. Analysis of the 171 simultaneous paired recordings of non-invasive ICP and the "gold standard" invasive CSF pressure on 110 neurological patients and TBI patients showed good accuracy for the non-invasive method as indicated by the low mean systematic error (0.12 mmHg; confidence level (CL) = 0.98). The method also showed high precision as indicated by the low standard deviation (SD) of the random errors

(SD = 2.19 mmHg; CL = 0.98).

This measurement method and technique (the only non-invasive ICP measurement technique which already received EU CE Mark approval) eliminates the main limiting problem of all other non-successful "correlation based" approaches to non-invasive ICP absolute value measurement - the need of calibration to the individual patient.

Intracranial pressure (ICP) needs to be directly measured before and after long duration flights to determine if microgravity causes the increased ICP. On the ground, lumbar puncture is the standard method of measuring cerebral spinal fluid pressure and ICP, but this carries additional risk in-flight. NASA is determining how to correlate ground-based MRI with inflight ultrasound and other methods of measuring ICP in space is currently being investigated.

To date, NASA has measured intraocular pressure (IOP), visual acuity, cycloplegic refraction, Optical Coherence Tomography (OCT) and A-scan axial length changes in the eye before and after spaceflight.

This disease is caused by problems in the circulatory system, so when it is presented, in the beginning it is important to follow several recommendations. The person needs to keep the legs elevated as much as possible to help the return of the blood. Whenever sitting down, the person needs to keep the legs on a foot stool. At night it is advisable to sleep with a pillow under the lower legs. In the evening, t is not unusual for legs to be swollen. The volume of the lower leg can increase to up to 100ml after a long working day or up to 200ml after a long-haul flight without moving.

In the example of the 41-year-old Japanese man the lesions were much improved by washing and topical use of corticosteroids for two months, also oral antibiotics like cephalexin are used if cellulitis is present. Moist exudative inflammation and moist ulcers respond to tepid wet compresses of Burow’s solution or just saline or water for 30 to 60 minutes several times a day. But in worse cases, edema that does not disappear spontaneously within a few hours or after a walk, is described as pathological, so it needs to have a special treatment. It is very important to say that Papillamitosis, bilateral and marked edema with few symptoms is mostly caused by the systemic circulation (heart, kidneys, liver).

Papillamitosis is associated, as has been mentioned before, with symptoms and/or clinical signs such as dilated superficial veins, varicose veins and changes in the skin. Edema and its complication Papillamitosis are only partially reversible and soon becomes hard, which is mainly confirmed on palpation. All skin structures are affected and this is characterized by the term. Lymphoedema may develop in many cases accompanied by acral thickening of the skin folds, hyperkeratosis and papillomatosis.

Symptoms are usually relieved with radiation therapy within one month of treatment. However, even with treatment, 99% of patients die within two and a half years. This relates to the cancerous causes of SVC that are 90% of the cases. The average age of onset of disease is 54 years of age.

According the Fifth WHO Expert Committee on Filariasis , the most common method of classification of lymphedema is as follows: (The same classification method can be used for both primary and secondary lymphedema)

The International Society of Lymphology (ISL) Staging System is based solely on subjective symptoms, making it prone to substantial observer bias. Imaging modalities have been suggested as useful adjuncts to the ISL staging to clarify the diagnosis. The lymphedema expert Dr. Ming-Huei Cheng developed a Cheng’s Lymphedema Grading tool to assess the severity of extremity lymphedema based on objective limb measurements and providing appropriate options for management.

Ultrasonography and magnetic resonance imaging of the hands and/or feet have been proposed as useful diagnostic investigations in RS3PE.

Some studies linked RS3PE to HLA-B27 whereas others have not.

Clinical signs of cerebral edema, such as focal neurological deficits, papilledema and decreased level of consciousness, if temporally associated with recent hemodialysis, suggest the diagnosis. A computed tomography of the head is typically done to rule-out other intracranial causes.

MRI of the head has been used in research to better understand DDS.

Generally, high-altitude pulmonary edema (HAPE) or AMS precede HACE. In patients with AMS, the onset of HACE is usually indicated by vomiting, headache that does not respond to non-steroidal anti-inflammatory drugs, hallucinations, and stupor. In some situations, however, AMS progresses to HACE without these symptoms. HACE must be distinguished from conditions with similar symptoms, including stroke, intoxication, psychosis, diabetic symptoms, meningitis, or ingestion of toxic substances. It should be the first diagnosis ruled out when sickness occurs while ascending to a high altitude.

HACE is generally preventable by ascending gradually with frequent rest days while climbing or trekking. Not ascending more than daily and not sleeping at a greater height than more than the previous night is recommended. The risk of developing HACE is diminished if acetazolamide or dexamethasone are administered. Generally, the use of acetazolamide is preferred, but dexamethasone can be used for prevention if there are side effects or contraindications. Some individuals are more susceptible to HACE than others, and physical fitness is not preventative. Age and sex do not by themselves affect vulnerability to HACE.

The incidence of clinical HAPE in unacclimatized travelers exposed to high altitude (~) appears to be less than 1%. The U.S. Army Pike's Peak Research Laboratory has exposed sea-level-resident volunteers rapidly and directly to high altitude; during 30 years of research involving about 300 volunteers (and over 100 staff members), only three have been evacuated with suspected HAPE.

Accurate diagnosis and staging are fundamental to the management of lymphedema patients. A swollen limb can result from different conditions that require different treatments. Diagnosis of lymphedema is currently based on history, physical exam, limb measurements, and imaging studies such as lymphoscintigraphy and indocyanine green lymphography. However, the ideal method for lymphedema staging to guide the most appropriate treatment is controversial because of several different proposed protocols.

Lymphedema can occur in both the upper and lower extremities, and in some cases, the head and neck. Assessment of the extremities first begins with a visual inspection. Color, presence of hair, visible veins, size and any sores or ulcerations are noted. Lack of hair may indicate an arterial circulation problem. Given swelling, the extremities' circumference is measured for reference as time continues. In early stages of lymphedema, elevating the limb may reduce or eliminate the swelling. Palpation of the wrist or ankle can determine the degree of swelling; assessment includes a check of the pulses. The axillary or inguinal nodes may be enlarged due to the swelling. Enlargement of the nodes lasting more than three weeks may indicate infection or other illnesses such as sequela from breast cancer surgery requiring further medical attention.

Diagnosis or early detection of lymphedema is difficult. The first signs may be subjective observations such as "my arm feels heavy" or "I have difficulty these days getting rings on and off my fingers". These may be symptomatic of early stage of lymphedema where accumulation of lymph is mild and not detectable by changes in volume or circumference. As lymphedema develops further, definitive diagnosis is commonly based upon an objective measurement of differences between the affected or at-risk limb at the opposite unaffected limb, e.g. in volume or circumference. No generally accepted criterion is definitively diagnostic, although a volume difference of 200 ml between limbs or a 4-cm difference (at a single measurement site or set intervals along the limb) is often used. Bioimpedance measurement (which measures the amount of fluid in a limb) offers greater sensitivity than existing methods.

Chronic venous stasis changes can mimic early lymphedema, but the changes in venous stasis are more often bilateral and symmetric. Lipedema can also mimic lymphedema, however lipedema characteristically spares the feet beginning abruptly at the medial malleoli (ankle level). Lipedema is common in overweight women. As a part of the initial work-up before diagnosing lymphedema, it may be necessary to exclude other potential causes of lower extremity swelling such as renal failure, hypoalbuminemia, congestive heart-failure, protein-losing nephropathy, pulmonary hypertension, obesity, pregnancy and drug-induced edema.

Stasis Papillomatosis is similar to AGEP (Acute generalized exanthematous pustulosis) from pustular psoriasis; criteria for histopathologic distinction have been proposed: papillary edema, vasculitis, exocytosis of eosinophils and single-cell necrosis of keratinocytes in AGEP and acanthosis and papillomatosis in pustular psoriasis.

An example that illustrates the difference between SP and Stasis Papillomatosis and the histology diagnosis is … “a markedly obese, 41-year-old Japanese man who had suffered from psoriasis vulgaris for several years visited hospital with elephantiasis-like swelling of his lower legs of three months' duration. His right lower leg showed marked papillomatosis with thick scales, and the left lower leg was eroded and papillomatous. Although direct lymphography of his lower extremities showed no abnormality, indirect lymphography revealed local lymphatic damage in the involved skin”. Histological examination showed hyperkeratosis, marked papillomatosis, proliferation of capillaries in the upper dermis, and lymphectasia in the lower dermis. It was suspected that obesity and the preceding psoriatic lesions caused local lymphatic disturbances, followed by the development of stasis papillomatosis.

Patients with HACE should be brought to lower altitudes and provided supplemental oxygen, and rapid descent is sometimes needed to prevent mortality. Early recognition is important because as the condition progresses patients are unable to descend without assistance. Dexamethasone should also be administered, although it fails to ameliorate some symptoms that can be cured by descending to a lower altitude. It can also mask symptoms, and they sometimes resume upon discontinuation. Dexamethasone's prevention of angiogenesis may explain why it treats HACE well. Three studies that examined how mice and rat brains react to hypoxia gave some credence to this idea.

If available, supplemental oxygen can be used as an adjunctive therapy, or when descent is not possible. FiO2 should be titrated to maintain arterial oxygen saturation of greater than 90%, bearing in mind that oxygen supply is often limited in high altitude clinics/environments.

In addition to oxygen therapy, a portable hyperbaric chamber (Gamow bag) can by used as a temporary measure in the treatment of HACE. These devices simulate a decrease in altitude of up to 7000 ft, but they are resource intensive and symptoms will often return after discontinuation of the device. Portable hyperbaric chambers should not be used in place of descent or evacuation to definitive care.

Diuretics may be helpful, but pose risks outside of a hospital environment. Sildenafil and tadalafil may help HACE, but there is little evidence of their efficacy. Theophylline is also theorized to help the condition.

Although AMS is not life-threatening, HACE is usually fatal within 24 hours if untreated. Without treatment, the patient will enter a coma and then die. In some cases, patients have died within a few hours, and a few have survived for two days. Descriptions of fatal cases often involve climbers who continue ascending while suffering from the condition's symptoms.

Recovery varies between days and weeks, but most recover in a few days. After the condition is successfully treated, it is possible for climbers to reascend. Dexamethesone should be discontinued, but continual acetazolamide is recommended. In one study, it took patients between one week and one month to display a normal CT scan after suffering from HACE.

For some types of chILD and few forms adult ILD genetic causes have been identified. These may be identified by blood tests. For a limited number of cases this is a definite advantage, as a precise molecular diagnosis can be done; frequently then there is no need for a lung biopsy. Testing is available for

The treatment of PRES dependent on its cause. Anti-epileptic medication may also be appropriate.

The standard and most important treatment is to descend to a lower altitude as quickly as possible, preferably by at least 1000 metres. Oxygen should also be given if possible. Symptoms tend to quickly improve with descent, but more severe symptoms may continue for several days. The standard drug treatments for which there is strong clinical evidence are dexamethasone and nifedipine. Phosphodiesterase inhibitors such as sildenafil and tadalafil are also effective but may worsen the headache of mountain sickness.

The diagnosis is typically made clinically with magnetic resonance imaging of the brain often revealing hyperintensities on "T"-weighed imaging. Three patterns have been described: superior frontal sulcus, dominant parieto-occipital, and holohemispheric watershed.

Management has generally been reported to be conservative, though deaths have been reported.

- Removal from water

- Observation

- Diuretics and / or Oxygen when necessary

- Episodes are generally self-limiting in the absence of other medical problems

Purpura hemorrhagica may be prevented by proper management during an outbreak of strangles. This includes isolation of infected horses, disinfection of fomites, and good hygiene by caretakers. Affected horses should be isolated at least one month following infection. Exposed horses should have their temperature taken daily and should be quarantined if it becomes elevated. Prophylactic antimicrobial treatment is not recommended.

Vaccination can reduce the incidence and severity of the disease. However, horses with high SeM antibody titers are more likely to develop purpura hemorrhagica following vaccination and so these horses should not be vaccinated. Titers may be measured by ELISA.

RS3PE responds excellently to low dose corticosteroids, with sustained and often complete remission. Non-steroidal anti-inflammatory drugs (NSAIDs) have also been used. Hydroxychloroquine has proven effective in some cases.

Avoidance is the primary treatment. Better alternatives are Nocturnal or Daily Dialysis, which are far more gentle processes for the new dialysis patient. Dialysis disequilibrium syndrome is a reason why hemodialysis initiation should be done gradually, i.e. it is a reason why the first few dialysis sessions are shorter and less aggressive than the typical dialysis treatment for end-stage renal disease patients.

Transfusion associated circulatory overload is prevented by avoiding unnecessary transfusions, closely monitoring patients receiving transfusions, transfusing smaller volumes of blood at a slower rate, and considering the use of diuretics. A pre-transfusion TACO checklist can be used to assess patients' risk of developing TACO.

Investigation is tailored towards the symptoms and signs. A proper and detailed history looking for the occupational exposures, and for signs of conditions listed above is the first and probably the most important part of the workup in patients with interstitial lung disease. Pulmonary function tests usually show a restrictive defect with decreased diffusion capacity (DLCO).

A lung biopsy is required if the clinical history and imaging are not clearly suggestive of a specific diagnosis or malignancy cannot otherwise be ruled out. In cases where a lung biopsy is indicated, a trans-bronchial biopsy is usually unhelpful, and a surgical lung biopsy is often required.
