  This may lead to headaches, fatigue and anxiety. The environment may be perceived as a distorted world. Stationary objects can blur, move and change. [autism.org.uk]

  Bats that survive the fungus manage to shrug off at least some of these waking impulses, or else they have the habit of eating more in the fall so they have better fat supplies to make it through the winter. [granitegeek.concordmonitor.com]

  Wolff-Parkinson-White syndrome often occurs with other structural abnormalities of the heart or underlying heart disease. [medlineplus.gov]

  WPW syndrome may occur with other types of congenital heart disease, such as Ebstein anomaly. Rarely, WPW syndrome is passed down through families (inherited). The inherited, or familial, type is associated with a thickened heart muscle. [mayoclinic.org]

• Hypotension

  Prescribing a medication for hypertension off one elevated blood pressure reading may lead to serious issues, including hypotension. Hypotension occurs when your blood pressure drops too low. [healthline.com]

  This approach could lead to problems, such as hypotension, where a person’s blood pressure drops too low. Hypotension can cause dizziness and fainting, especially on standing up. Instead, the doctor will take multiple readings. [medicalnewstoday.com]

  Very rapid heartbeats, a complication of Wolff-Parkinson-White, can result in severe hypotension and syncope, or loss of consciousness. Causes Normally, electrical signals follow a certain pathway through the heart. [mountsinai.org]

  Hypotension, by causing a sympathetic response, can further shorten the refractory period and ventricular fibrillation may result. The appearance is irregular, variable QRS (normal to wide complex), at rates often around 250 beats per minute. [patient.info]

  Importantly, with judicious dose monitoring and adjustment, none of the patients experienced hypotension during the therapeutic course, excluding the possibility that pathogenic hypoperfusion was caused by the medication. [jamanetwork.com]

• Hypertension

  In a 2015 study involving 3,027 people, 3.3% had white coat hypertension, and 17.8% had masked hypertension. Some experts believe that white coat hypertension is due to the stress people experience when visiting a healthcare center. [medicalnewstoday.com]

  A study found that patients over 60 who experience white coat hypertension in conjunction with other risk factors had a higher risk of a cardiovascular event. You can read the article on reuters here. Journal articles can be found here and here. [heartcareimaging.com]

  White coat hypertension causes temporary increases in your blood pressure. While it might not seem serious if it occurs only occasionally, some doctors believe white coat hypertension could be a forerunner of real hypertension. [healthline.com]

  Seven patients (11%) had a history of hypertension, and 28 (43%) exhibited blood pressure surges during headache attacks. Sixteen patients (25%) had a history of migraine. None of the patients had diabetes or coronary artery disease. [jamanetwork.com]

• Blurred Vision

  Symptoms of MEWDS include unilateral blurred vision, visual field loss, photopsias, and floaters. The various diagnoses are differentiated by history, appearance, laterality, and fluorescein angiogram findings. [eyewiki.aao.org]

• Hearing Impairment

  Additional features may include hypotonia, seizures, sleep apnea, sensorineural hearing impairment, visual defects (strabismus, refraction errors), tendency to be overweight, short stature and gastrointestinal difficulties. [orpha.net]

  Some affected individuals may also have hearing impairment due to abnormalities of the inner ear (sensorineural deafness). [rarediseases.org]

• Suggestibility

  “This suggests that conservation of summer foraging habitat—not just winter hibernation sites—may promote population recovery in bats affected by white-nose syndrome.” [futurity.org]

  “Our initial studies suggest that an effective vaccine could be a critical step towards conserving North America’s bat populations.” [usgs.gov]

  As mentioned above, evidence suggests that the MITF gene is regulated by the PAX3 gene. [rarediseases.org]

  We suggest fundus autofluorescence is used in all cases of suspected MEWDS and believe this disease entity may more often be bilateral than previously recognized using clinical examination alone. [ncbi.nlm.nih.gov]

  Your doctor may also suggest you try vagal manoeuvres when having an episode of WPW. These are things, like bearing down, that might help slow your heart rate. [myhealth.alberta.ca]

  Along with a delta wave, patients have a shorter time between the conduction of an impulse from the atrium to the ventricle, referred to as a short PR interval (see the ECG in Figure 2). [ahajournals.org]

  short PR, QRS >120 ms, and delta wave. [emedicine.medscape.com]

  Classic ECG findings of WPW syndrome include a short PR interval (less than 120 ms), a prolonged QRS complex of longer than 120 ms with a slurred onset producing a delta wave in the early part of QRS and secondary ST-T wave changes[2, 9]. [patient.info]

• Right Bundle Branch Block

  The dominant R wave in lead V1 may be misinterpreted as right bundle branch block. Type B: the delta wave and QRS complex are predominantly negative in leads V1 and V2 and positive in the other precordial leads, resembling left bundle branch block. [patient.info]

  The orthodromic reciprocating tachycardia in such patients often exhibits right bundle-branch block (RBBB) and a long ventriculoatrial (VA) interval. [emedicine.medscape.com]

Research on potential treatment using UV light is under way. [sciencedaily.com]

More work is needed to determine if UV light treatment will result in increased survival rates, but the hope is that treatment will enable more bats to survive hibernation. [fs.fed.us]

Preliminary results indicate that UV-treated bats had less of the fungal pathogen compared to untreated bats up to 15 weeks after treatment, and no negative treatment effects were observed. [fs.usda.gov]

The goals of treatment are to slow a fast heart rate when it occurs and to prevent future episodes. Treatment options for a fast heart rate include: Vagal maneuvers. [mayoclinic.org]

Prognosis Prognosis is usually very good once treated[15]. Catheter ablation may be curative. The prognosis depends on the intrinsic electrophysiological properties of the accessory pathway rather than on symptoms[16]. [patient.info]

Visual prognosis is excellent. Exam Findings On fundus exam, one sees flat, multifocal, grey-white lesions (100-200 microns), appearing to reach as deep as the RPE. Typically lesions are found outside the fovea in the posterior pole. [eyewiki.aao.org]

In the great majority of patients, the prognosis of TMD is good with complete resolution of the disease without any treatment; however, a few patients with TMD don’t show improvement and develop cancer in the blood or leukemia. [ndss.org]

Prognosis There is currently no data on life expectancy but there is no known complication that could lead to early death. [orpha.net]

Certain factors affect prognosis (chance of recovery) and treatment options. The prognosis and treatment options depend on the following: The number of blast cells in the bone marrow. Whether one or more types of blood cells are affected. [cancer.gov]

Etiology The disorder is caused by heterozygous pathogenic variants in POGZ. POGZ gene mutations are thought to impair the ability of the POGZ protein to bind to chromatin. [orpha.net]

Pathogenesis and Treatment Frequently, a viral prodrome is elicited from the patient, though an infectious etiology is yet to be elucidated. The exact pathogenesis is unknown. [eyewiki.aao.org]

A viral prodrome without any other systemic manifestations may precede the ophthalmic findings.3 However, multimodal imaging is helpful in diagnosing the disease and differentiating it from other inflammatory and infectious etiologies. [ncbi.nlm.nih.gov]
