Microscopic analysis of the hair shows twisted hairs of unequal size and different shapes (pili torti, aniso- and poikilotrichosis), longitudinal breaks and breaks located at nodes (trichorrhexis nodosa). Scanning electron microscopy might reveal hair budding (trichorrhexis blastysis). Biochemical analysis may reveal sulfur-deficient brittle hair (trichothiodystrophy; note that disulfide bonds determine hair waviness).

Immunodeficiency is a consistent feature with low serum concentrations of immunoglobulins which may improve with age and a poor immunological response to childhood vaccination. T cell dysfunction and abnormal antibody generation have been reported.

The diagnosis of pyruvate kinase deficiency can be done by full blood counts (differential blood counts) and reticulocyte counts. Other methods include direct enzyme assays, which can determine pyruvate kinase levels in erythrocytes separated by density centrifugation, as well as direct DNA sequencing. For the most part when dealing with pyruvate kinase deficiency, these two diagnostic techniques are complementary to each other as they both contain their own flaws. Direct enzyme assays can diagnose the disorder and molecular testing confirms the diagnosis or vice versa. Furthermore, tests to determine bile salts (bilirubin) can be used to see whether the gall bladder has been compromised.

Prenatal screening is not typically done for FHM, however it may be performed if requested. As penetrance is high, individuals found to carry mutations should be expected to develop signs of FHM at some point in life.

"See the equivalent section in the main migraine article."

People with FHM are encouraged to avoid activities that may trigger their attacks. Minor head trauma is a common attack precipitant, so FHM sufferers should avoid contact sports. Acetazolamide or standard drugs are often used to treat attacks, though those leading to vasoconstriction should be avoided due to the risk of stroke.

At present there is no specific treatment. Many patients with haemolytic anaemia take folic acid (vitamin B) since the greater turnover of cells consumes this vitamin. During crises transfusion may be required. Clotting problems can occur for which anticoagulation may be needed. Unlike hereditary spherocytosis, splenectomy is contraindicated.

Diagnosis of TNDM and PNDM

The diagnostic evaluations are based upon current literature and research available on NDM. The following evaluation factors are: patients with TNDM are more likely to have intrauterine growth retardation and less likely to develop ketoacidosis than patients with PNDM. TNDM patients are younger at the age of diagnosis of diabetes and have lower insulin requirements, an overlap occurs between the two groups, therefore TNDM cannot be distinguished from PNDM based clinical feature. An early onset of diabetes mellitus is unrelated to autoimmunity in most cases, relapse of diabetes is common with TNDM, and extensive follow ups are important. In addition, molecular analysis of chromosomes 6 defects, KCNJ11 and ABCC8 genes (encoding Kir6.2 and SUR1) provide a way to identify PNDM in the infant stages. Approximately,50% of PNDM are associated with the potassium channel defects which are essential consequences when changing patients from insulin therapy to sulfonylureas.

TNDM Diagnosis associated with Chromosome 6q24 Mutations

The uniparental disomy of the chromosome can be used as diagnostic method provide proof by the analysis of polymorphic markers is present on Chromosome 6. Meiotic segregation of the chromosome can be distinguished by comparing allele profiles of polymorphic makers in the child to the child's parents' genome. Normally, a total uniparental disomy of the chromosome 6 is evidenced, but partial one can be identified. Therefore, genetic markers that are close to the region of interest in chromosome 6q24 can be selected. Chromosome duplication can found by that technique also.

Diagnostic Test of NDM

- "Fasting plasma glucose test": measures an diabetic's blood glucose after he or she has gone 8 hours without eat. This test is used to detect diabetes or pre-diabetes

- "Oral glucose tolerance test"- measures an individual's blood glucose after he or she have gone at least 8 hours without eating and two hours after the diabetic individual have drunk a glucose-containing beverage. This test can be used to diagnose diabetes or pre-diabetes

- "Random plasma glucose test"-the doctor checks one's blood glucose without regard to when an individual may have ate his or her last meal. This test, along with an evaluation of symptoms, are used to diagnose diabetes but not pre-diabetes.

Genetic Testing of NDM

- "Uniparental Disomy Test:"

Samples from fetus or child and both parents are needed for analysis. Chromosome of interest must be specified on request form. For prenatal samples (only): if the amniotic fluid (non-confluent culture cells) are provided. Amniotic fluid is added and charged separately. Also, if chorionic villus sample is provided, a genetic test will be added and charged separately. Microsatellites markers and polymerase chain reaction are used on the chromosomes of interest to test the DNA of the parent and child to identify the presence of uni"parental disomy""."

- Intrauterine Growth Restriction

"Apgar score is" a test given after birth to test the baby's physical condition and evaluate if special medical care is needed.

Pyruvate kinase deficiency happens worldwide, however northern Europe, and Japan have many cases. The prevalence of pyruvate kinase deficiency is around 51 cases per million in the population (via gene frequency).

In 2011, Howard proposed a refinement of the standard Cairo-Bishop definition of TLS accounting for 2 limitations:

- Two or more electrolyte laboratory abnormalities must be present simultaneously to be considered related to TLS. In fact, some patients may present with one abnormality, but later another one may develop that is unrelated to the TLS (e.g., hypocalcemia associated with sepsis).

- A 25% change from baseline should not be considered a criterion since such increases are rarely clinically important unless the value is already outside the normal range.

Moreover, any symptomatic hypocalcemia should constitute clinical TLS.

Diagnosis of oculocerebrorenal syndrome can be done via genetic testing Among the different investigations that can de done are:

- Urinalysis

- MRI

- Blood test

White blood counts exceeding 100 x 10^9 / L (100,000 / microL) present symptoms of tissue hypoxia and may signal possible neurological and respiratory distress. Continuing research has shown that patients have suffered from hypoxia at leukocyte levels below 100 x 10^9 / L (100,000 / microL), therefore patients with leukemia need regular neurological and respiratory monitoring when leukocyte counts are approaching 100 x 10^9 / L (100,000 / microL) to decrease chances of tissue hypoxia. Biopsy's acquired are examined for damage to microvasculature, which serves as evidence of hypoxia through the identification of leukocyte blockage within the tissue. Due to a biopsy's invasive nature and the risks associated with the procedure, it is only used when deemed necessary.

Measurements for arterial pO2 have shown to be falsely decreased in patients with hyperleuckocytosis because of white blood cells ability to utilize oxygen. Pulse oximetry should be used to more accurately assess pO2 levels of a patient suspected to be suffering from leukocytosis.

Automated blood cell counters may be inaccurate due to fragments of blast cells being labeled on blood smears as platelets. The most accurate form of confirming platelet counts is by using a manual platelet count and review of a peripheral smear.

Serum potassium levels may also be artificially elevated caused by a release from leukemic blasts during in vitro clotting process, therefore serum potassium levels should be monitored by herparinized (the addition of herapin prevents coagulation) plasma samples in order to obtain accurate results of potassium levels.

Disseminated intravascular coagulation may occur in a significant amount of patients with presentation of various degrees of thrombin generation, followed by decreased fibrinogen and increased fibrinolysis.

Spontaneous tumor lysis syndrome is present in approximately 10 percent of patients with leuckostasis, lab tests are used to measure the potential of elevated serum concentrations such as uric acid, potassium, phosphate, and hyocalcemia.

Disseminated intravascular coagulation and spontaneous tumor lysis syndrome have the ability to develop before and after chemotherapy treatment. Patients undergoing this type of therapy need to be closely monitored before and after in addition to undergoing prophylactic measures to prevent possible complications.

Diagnosis of paramyotonia congenita is made upon evaluation of patient symptoms and case history. Myotonia must increase with exercise or movement and usually must worsen in cold temperatures. Patients that present with permanent weakness are normally not characterized as having PC. Electromyography may be used to distinguish between paramyotonia congenita and myotonia congenita. Clinicians may also attempt to provoke episodes or myotonia and weakness/paralysis in patients in order to determine whether the patient has PC, hyperkalemic periodic paralysis, or one of the potassium-aggravated myotonias. Genomic sequencing of the SCN4A gene is the definitive diagnostic determinant.

Nitric acid test and paper chromatography test are used in the detection of argemone oil.Paper chromatography test is the most sensitive test.

It is an acute syndrome requiring aggressive cytoreductive including chemotherapy and/or leukapheresis to both reduce the number of circulating leukocytes and to break apart any aggregates that have already formed. Such rapid and massive lysis of tissue poses risk of complications (tumor lysis syndrome), but it is necessary to avoid stroke.

Leukostasis is different from leukemic infiltration which is a neoplastic process where leukemic cells invade organs.

Haematologists have identified a number of variants. These can be classified as below.

- Overhydrated hereditary stomatocytosis

- Dehydrated HSt (hereditary xerocytosis; hereditary hyperphosphatidylcholine haemolytic anaemia)

- Dehydrated with perinatal ascites

- Cryohydrocytosis

- 'Blackburn' variant.

- Familial pseudohyperkalaemia

There are other families that do not fall neatly into any of these classifications.

Stomatocytosis is also found as a hereditary disease in Alaskan malamute and miniature schnauzer dogs.

In 2004, Cairo and Bishop defined a classification system for tumor lysis syndrome.

- Laboratory tumor lysis syndrome: abnormality in two or more of the following, occurring within three days before or seven days after chemotherapy.

- uric acid > 8 mg/dL or 25% increase

- potassium > 6 meq/L or 25% increase

- phosphate > 4.5 mg/dL or 25% increase

- calcium < 7 mg/dL or 25% decrease

- Clinical tumor lysis syndrome: laboratory tumor lysis syndrome plus one or more of the following:

- increased serum creatinine (1.5 times upper limit of normal)

- cardiac arrhythmia or sudden death

- seizure

A grading scale (0-5) is used depending on the presence of lab TLS, serum creatinine, arrhythmias, or seizures.

Dogs with infected with the whipworm "Trichuris trichiura" can exhibit low sodium and high potassium values, as is seen in hypoadrenocorticism; however, their ACTH values are normal.

Breeds that began in the Pacific Rim, among them Akitas and Shiba Inus, tend to have higher potassium values in laboratory test, and elevated levels are not abnormal. Dogs who do not have hypoadrenocorticism have normal values on ACTH tests.

Recent diagnostic criteria have been published out of the Arrhythmia Research Laboratory at the University of Ottawa Heart Institute from Drs. Michael H Gollob and Jason D Roberts.

The Short QT Syndrome diagnostic criterion is based on a point system as follows:

QTc in milliseconds

Jpoint-Tpeak interval

Clinical History

Family History

Genotype

Patients are deemed high-probability (> or equal to 4 points), intermediate probability (3 points) or low probability (2 or less points).

Characterised as a recessive disorder, symptomatic presentation requires the inheritance of aldolase A mutations from both parents. This conclusion is substantiated through the continuum type presentation witnessed, wherein heterozygous parents have intermediate enzyme activity. Structural instability has been indicated in four of the patients, with particular sensitivity to increased temperature according to direct enzymatic testing. This is exemplified in the early diagnosis of hereditary pyropoikilocytosis in the Sicilian girl. Deterioration with fever is likewise congruent. However, this direct relation has been disputed due to the increased overall metabolism and oxygen consumption also accompanying such maladies.

Sequence analysis has been conducted for three of the patients each revealing a distinct alteration at regions of typically high conservation. The conversion of the 128th aspartic acid to glycine causes conformational change according to CD spectral analysis and thermal lability in mutagenic analysis. Similarly the charge disruption created through the exchange of the negatively charged glutamic acid for positively charged lysine (at residue 209 of the E helix) disrupts interface interaction of the protein's subunits and therein destabilises its native tetrahedral configuration. The final case is unique in its non-homozygosity. A comparable maternal missense mutation wherein tyrosine is replaced by cysteine alters the carboxy-terminus due to its proximity to a crucial hinge structure. However, the paternal nonsense mutation at arginine 303 truncates the peptide. It is notable that Arg303 is required for enzymatic activity.

The initial 1973 case is atypical, in that no indication of aldolase A structural abnormality was found in isoelectric focusing, heat stabilization, electrophoresis or enzyme kinetics. It was concluded that either disordered regulation or a basic defect creating more rapid tetrameric inactivation were the most probable causes.

Causes of NDM

PNDM and TNDM are inherited genetically from the mother or father of the infant. Different genetic inheritance or genetic mutations can lead to different diagnosis of NDM (Permanent or Transient Neonatal Diabetes Mellitus). The following are different types of inheritance or mutations:

- "Autosomal Dominant": Every cell has two copies of each gene-one gen coming from the mother and one coming from the father. Autosomal dominant inheritance pattern is defined as a mutation that occurs in only one copy of the gene. A parent with the mutation can pass on a copy of the gene and a parent with the mutation can pass on a copy of their working gene (or a copy of their damaged gene). In an autosomal dominant inheritance, a child who has a parent with the mutation has a 50% possibility of inheriting the mutation.

- "Autosomal Recessive" -Autosomal recessive-Generally, every cells have two copies of each gene-one gene is inherited from the mother and one gene is inherited from the father. Autosomal recessive inheritance pattern is defined as a mutation present in both copies if the gene in order for a person to be affected and each parent much pass on a mutated gene for a child to be affected. However, if an infant or child has only one copy, he or she are a carrier of the mutation. If moth parents are carriers of the recessive gene mutation, each child have a 25% chance of inheriting the gene.

- "Spontaneous": A new mutation or change occurs within the gene.

- "X-linked:" When a trait or disease happens in a person who has inherited a mutated gene on the X chromosome (one of the sex chromosome).

Prevention: There are no current prevention methods, because TNDM or PNDM are inherited genetically.

Evaluation of a child with persistent high blood pressure usually involves analysis of blood electrolytes and an aldosterone level, as well as other tests. In Liddle's disease, the serum sodium is typically elevated, the serum potassium is reduced, and the serum bicarbonate is elevated. These findings are also found in hyperaldosteronism, another rare cause of hypertension in children. Primary hyperaldosteronism (also known as Conn's syndrome), is due to an aldosterone-secreting adrenal tumor (adenoma) or adrenal hyperplasia. Aldosterone levels are high in hyperaldosteronism, whereas they are low to normal in Liddle syndrome.

A genetic study of the ENaC sequences can be requested to detect mutations (deletions, insertions, missense mutations) and get a diagnosis.

Mutations in the "SCN4A" gene cause potassium-aggravated myotonia. The "SCN4A" gene provides instructions for making a protein that is critical for the normal function of skeletal muscle cells. For the body to move normally, skeletal muscles contract and relax in a coordinated way. Muscle contractions are triggered by the flow of positively charged ions, including sodium, into skeletal muscle cells. The "SCN4A" protein forms channels that control the flow of sodium ions into these cells. Mutations in the "SCN4A" gene alter the usual structure and function of sodium channels. The altered channels cannot properly regulate ion flow, increasing the movement of sodium ions into skeletal muscle cells. The influx of extra sodium ions triggers prolonged muscle contractions, which are the hallmark of myotonia.

Potassium-aggravated myotonia is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. In some cases, an affected person inherits a mutation in the "SCN4A" gene from one affected parent. Other cases result from new mutations in the gene. These cases occur in people with no history of the disorder in their family.

In terms of treatment of oculocerebrorenal syndrome for those individuals who are affected by this condition includes the following:

- Glaucoma control (via medication)

- Nasogastric tube feeding

- Physical therapy

- Clomipramine

- Potassium citrate

EAST syndrome is an autosomal recessive disorder; therefore, it cannot necessarily be prevented. Presence of the four symptoms (epilepsy, ataxia, sensorineural deafness, and salt-wasting renal tubulopathy) and detection of a mutation in the KCNJ10 gene would indicate the presence of this disorder.

There is not yet one method to help EAST syndrome as a whole, but hopefully with continued research, there could be one day.
