Biochemical blood tests determine the amount of typical markers of renal function in the blood serum, for instance serum urea and serum creatinine. Biochemistry can also be used to determine serum electrolytes. Special biochemical tests (arterial blood gas) can determine the amount of dissolved gases in the blood, indicating if pH imbalances are acute or chronic.

Urinalysis is a test that studies urine for abnormal substances such as protein or signs of infection.

- A Full Ward Test, also known as dipstick urinalysis, involves the dipping of a biochemically active test strip into the urine specimen to determine levels of tell-tale chemicals in the urine.

- Urinalysis can also involve MC&S microscopy, culture and sensitivity

Urodynamic tests evaluate the storage of urine in the bladder and the flow of urine from the bladder through the urethra. It may be performed in cases of incontinence or neurological problems affecting the urinary tract.

Ultrasound is commonly performed to investigate problems of the kidney and/or urinary tract.

Radiology:

- KUB is plain radiography of the urinary system, e.g. to identify kidney stones.

- An intravenous pyelogram studies the shape of the urinary system.

- CAT scans and MRI can also be useful in localising urinary tract pathology.

- A voiding cystogram is a functional study where contrast "dye" is injected through a catheter into the bladder. Under x-ray the radiologist asks the patient to void (usually young children) and will watch the contrast exiting the body on the x-ray monitor. This examines the child's bladder and lower urinary tract. Typically looking for vesicoureteral reflux, involving urine backflow up into the kidneys.

Amniotic band syndrome is considered an accidental event and it does not appear to be genetic or hereditary, so the likelihood of it occurring in another pregnancy is remote. The cause of amnion tearing is unknown and as such there are no known preventative measures.

Amniotic band syndrome is often difficult to detect before birth as the individual strands are small and hard to see on ultrasound. Often the bands are detected indirectly because of the constrictions and swelling upon limbs, digits, etc. Misdiagnosis is also common, so if there are any signs of amniotic bands, further detailed ultrasound tests should be done to assess the severity. 3D ultrasound and MRI can be used for more detailed and accurate diagnosis of bands and the resulting damage/danger to the fetus.

The most reliable test for EPI in dogs and cats is serum trypsin-like immunoreactivity (TLI). A low value indicates EPI. Fecal elastase levels may also be used for diagnosis in dogs.

In dogs, the best treatment is to supplement its food with dried pancreatic extracts. There are commercial preparations available, but chopped bovine pancreas from the butcher can also be used (pork pancreas should not be used because of the rare transmission of pseudorabies). Symptoms usually improve within a few days, but lifelong treatment is required to manage the condition. A rare side-effect of use of dried pancreatic extracts is oral ulceration and bleeding.

Because of malabsorption, serum levels of cyanocobalamin (vitamin B12) and tocopherol (vitamin E) may be low. These may be supplemented, although since cyanocobalamin contains the toxic chemical cyanide, dogs that have serious cobalamin issues should instead be treated with hydroxocobalamin or methylcobalamin. Cyanocobalamin deficiency is very common in cats with EPI because about 99 percent of intrinsic factor (which is required for cyanocobalamin absorption from the intestine) is secreted by the pancreas. In dogs, this figure is about 90 percent, and only about 50 percent of dogs have this deficiency. Cats may suffer from Vitamin K deficiencies. If there is bacterial overgrowth in the intestine, antibiotics should be used, especially if treatment is not working. In dogs failing to gain weight or continuing to show symptoms, modifying the diet to make it low-fiber and highly digestible may help. Despite previous belief that low-fat diets are beneficial in dogs with EPI, more recent studies have shown that a high-fat diet may increase absorption of nutrients and better manage the disease. However, it has been shown that different dogs respond to different dietary modifications, so the best diet must be determined on a case-by-case basis.

One possible sequela, volvulus (mesenteric torsion) is a rare consequence of EPI in dogs.

The causes of diseases of the body are common to the urinary tract. Structural and or traumatic change can lead to hemorrhage, functional blockage or inflammation. Colonisation by bacteria, protozoa or fungi can cause infection. Uncontrolled cell growth can cause neoplasia.

For example:

- Urinary tract infections (UTIs), interstitial cystitis

- incontinence (involuntary loss of urine), benign prostatic hyperplasia (where the prostate overgrows), prostatitis (inflammation of the prostate).

- Urinary retention, which is a common complication of benign prostatic hyperplasia (BPH), though it can also be caused by other types of urinary tract obstruction, nerve dysfunction, tethered spinal cord syndrome, constipation, infection and certain medications.

- Transitional cell carcinoma (bladder cancer), renal cell carcinoma (kidney cancer), and prostate cancer are examples of neoplasms affecting the urinary system.

- Urinary tract obstruction

The term "uropathy" refers to a disease of the urinary tract, while "nephropathy" refers to a disease of the kidney.

Blood tests should be done, importantly liver-function series, which will give a good impression of the patient's broad metabolic picture.

A complete blood test can help distinguish intrinsic liver disease from extrahepatic bile-duct obstruction. An ultrasound of the liver can reliably detect a dilated biliary-duct system,

it can also detect the characteristics of a cirrhotic liver.Computerized tomography (CT) can help to obtain accurate anatomical information, in individuals with hepatomegaly.

The three main tests used in considering a diagnosis of EPI are Fecal elastase test, fecal fat test, and a direct pancreatic function test. The latter being a limitedly used test that assesses exocrine function in the pancreas by inserting a tube into the small intestine to collect pancreatic secretions.

The prognosis for children with NMDs varies depending on the specific disorder and the degree of brain abnormality and subsequent neurological signs and symptoms.

EMG &NCV can help to treatment with the diagnosis of the location and severity of the lesion.

treatment to be directed towards the findings in investigation if it is found to be AMAG immunosupressive drugs and chemotherapy with antineoplastic drugs.

In case of confirmed malignancy of stomach complete or step ladder or stage ladder resection of gastric or stomach to be done.

There are several treatments available for bleeding due to factor X deficiency, however a specifi FX concentrate is not available (2009).

1. Prothrombin complex concentrate (PCC) supplies FX with a risk of thrombosis.

2. Fresh frozen plasma (FFP): This is relatively inexpensive and readily available. While effective this treatment carries a risk of blood-borne viruses and fluid overload.

3. If vitamin K levels are low, vitamin K can be supplied orally or parenterally.

Treatment of FX deficiency in amyloidosis may be more complex and involve surgery (splenectomy) and chemotherapy.

Treatment is symptomatic, and may include anti-seizure medication and special or supplemental education consisting of physical, occupational, and speech therapies.

Atrophic gastritis is classified depending on the level of progress as "close type" or "open type". This classification was advocated by Takemoto and Kimura of Tokyo University at 1966.

Since the essential pathology is due to the inability to absorb vitamin B from the bowels, the solution is therefore injection of IV vitamin B. Timing is essential, as some of the side effects of vitamin B deficiency are reversible (such as RBC indices, peripheral RBC smear findings such as hypersegmented neutrophils, or even high levels of methylmalonyl CoA), but some side effects are irreversible as they are of a neurological source (such as tabes dorsalis, and peripheral neuropathy). High suspicion should be exercised when a neonate, or a pediatric patient presents with anemia, proteinuria, sufficient vitamin B dietary intake, and no signs of pernicious anemia.

The first cases of NSF were identified in 1997, but NSF was first described as an independent disease entity in 2000. While skin involvement is on the foreground, the process may involve any organ and resembles diffuse scleroderma or systemic sclerosis. In 2006, the link between NSF and gadolinium-containing contrast agents was made. As a result, gadolinium-containing contrast is now considered contraindicated in patients with an estimated glomerular filtration rate (a measure of renal function) under 60 and especially under 30 ml/mn. One retrospective study of the Veterans Affairs Electronic Medical Record found no cases of NSF among 141 patients receiving hemodialysis for chronic kidney disease who received gadoteridol.

Blood tests are needed to differentiate FX deficiency from other bleeding disorders. Typical are normal thrombin time, prolonged prothrombin time (PT) and prolonged partial thromboplastin time(PTT). FX antigen and its coagulant activity can be used to classify the severity of the condition:

1. Type I has low levels of FX antigen and activity.

2. Type II has low coagulant activity but normal or borderline FX antigen levels.

The FX (F10) gene is found on chromosome 13q34. Heterogeneous mutations have been described in FX deficient patients.

This is a rare disease with prevalence about 1 in 200,000 to 1 in 600,000. Studies showed that mutations in "CUBN" or "AMN" clustered particularly in the Scandinavian countries and the Eastern Mediterranean regions. Founder effect, higher clinical awareness to IGS, and

frequent consanguineous marriages all play a role in the higher prevalence of IGS among these populations

There are multiple classifications for the triphalangeal thumb. The reason for these different classifications is the heterogeneity in appearance of the TPT.

The classification according to Wood describes the shape of the extra phalanx: delta (Fig. 4), rectangular or full phalanx (Table 1). With the classification made by Buck-Gramcko a surgical treatment can be chosen (Table 1). Buck-Gramcko differentiates between six different shapes of the extra phalanx and associated malformations.

Table 1: Classifications of Wood and Buck-Gramcko

In most cases, liver function will return to normal if the offending drug is stopped early. Additionally, the patient may require supportive treatment. In acetaminophen toxicity, however, the initial insult can be fatal. Fulminant hepatic failure from drug-induced hepatotoxicity may require liver transplantation. In the past, glucocorticoids in allergic features and ursodeoxycholic acid in cholestatic cases had been used, but there is no good evidence to support their effectiveness.

An elevation in serum bilirubin level of more than 2 times ULN with associated transaminase rise is an ominous sign. This indicates severe hepatotoxicity and is likely to lead to mortality in 10% to 15% of patients, especially if the offending drug is not stopped (Hy's Law). This is because it requires significant damage to the liver to impair bilirubin excretion, hence minor impairment (in the absence of biliary obstruction or Gilbert syndrome) would not lead to jaundice. Other poor predictors of outcome are old age, female sex, high AST.

This remains a challenge in clinical practice due to a lack of reliable markers. Many other conditions lead to similar clinical as well as pathological pictures. To diagnose hepatotoxicity, a causal relationship between the use of the toxin or drug and subsequent liver damage has to be established, but might be difficult, especially when idiosyncratic reaction is suspected. Simultaneous use of multiple drugs may add to the complexity. As in acetaminophen toxicity, well established, dose-dependent, pharmacological hepatotoxicity is easier to spot. Several clinical scales such as CIOMS/RUCAM scale and Maria and Victorino criteria have been proposed to establish causal relationship between offending drug and liver damage. CIOMS/RUCAM scale involves a scoring system that categorizes the suspicion into "definite or highly probable" (score > 8), “probable” (score 6-8), “possible” (score 3-5), “unlikely” (score 1-2) and “excluded” (score ≤ 0). In clinical practice, physicians put more emphasis on the presence or absence of similarity between the biochemical profile of the patient and known biochemical profile of the suspected toxicity (e.g., cholestatic damage in amoxycillin-clauvonic acid ).

The European Medicines Agency has classified the gadolinium-containing contrast agents into three risk groups:

- Least likely (safest) to release free gadolinium ions Gd(III) (also written Gd) in the body have a macrocyclic structure: gadoterate (Dotarem), gadobutrol (Gadavist) and gadoteridol (ProHance)

- Intermediate have an ionic linear structure: gadopentetate (Magnevist), gadobenate (MultiHance), gadoxetate and gadofosveset

- Most likely to release Gd (III) have a linear non-ionic structure: gadodiamide (Omniscan) and gadoversetamide

The suitability of gadolinium complexes as magnetic resonance imaging contrast agents depends on a number of factors. A thermodynamic relationship to toxicity exists if one assumes that the chemotoxicity of the intact complex is minimal but that the toxicity of the components of the complex (free metal and uncomplexed ligands) is substantial.

Release of Gd(III) from the complex is responsible for the toxicity associated with gadolinium complexes; this release appears to be a consequence of Zn, Cu, and Ca transmetallation in vivo. This hypothesis is supported by acute toxicity experiments, which demonstrate that despite a 50-fold range of LDse values for four Gd(III) complexes, all become lethally toxic when they release precisely the same quantity of Gd(III). It is also supported by subchronic rodent toxicity experiments, which demonstrate a set of gross and microscopic findings similar to those known to be caused by Zn deficiency. Finally, this hypothesis predicts that subtle changes in formulation can further enhance the intrinsic safety of these complexes. The added Ca salt of the ligand must have a favorable toxicity so that the decrease in toxicity from in vivo transmetallation is not offset, or overcome, by the addition of a toxic component to the formulation.

In terms of treatment for pulmonary valve stenosis, valve replacement or surgical repair (depending upon whether the stenosis is in the valve or vessel) may be indicated. If the valve stenosis is of congenital origin, balloon valvuloplasty is another option, depending on the case.

Valves made from animal or human tissue (are used for valve replacement), in adults metal valves can be used.

Normal olfactory acuity will usually return over time if the cause is environmental, even if it is untreated. The hyperosmic person may need to be removed from strong odorants for a period of time if the sensation becomes unbearable. Before they had been discontinued due to undesirable side effects, butyrophenones or thioridazine hydrochloride, both of which are dopamine antagonists, have been used to treat hyperosmia.

The goals of surgical treatment are: reducing length of the thumb, creating a good functioning, a stable and non deviated joint and improving the position of the thumb if necessary. Hereby improving function of the hand and thumb.

In general the surgical treatment is done for improvement of the thumb function. However, an extra advantage of the surgery is the improvement in appearance of the thumb. In the past, surgical treatment of the triphalangeal thumb was not indicated, but now it is generally agreed that operative treatment improves function and appearance. Because an operation was not indicated in the past, there’s still a population with an untreated triphalangeal thumb. The majority of this population doesn’t want surgery, because the daily functioning of the hand is good. The main obstacle for the untreated patients might not be the diminished function, but the appearance of the triphalangeal thumb.

The timing of surgery differs between Wood and Buck-Gramcko. Wood advises operation between the age of six months and two years, while Buck-Gramcko advises to operate for all indications before the age of six years.

- For TPT types I and II of the Buck-Gramcko classification, the surgical treatment typically consists of removing the extra phalanx and reconstructing the ulnar collateral ligament and the radial collateral ligament if necessary.

- For type III of Buck-Gramcko classification proposable surgical treatments:

- For type IV of Buck-Gramcko classification the surgical treatment typically consists of an osteotomy which reduces the middle phalanx and arthrodesis of the DIP. This gives a shortening of 1 to 1.5 cm. In most cases, this technique is combined with a shortening, rotation and palmar abduction osteotomy at metacarpal level to correct for position and length of the thumb. The extensor tendons and the intrinsic muscles are shortened as well.

- For type V of the Buck-Gramcko classification the surgical treatment proposably consists of a "pollicization". With a pollicization the malpositioned thumb is repositioned, rotated and shortened, the above-described rotation reduction osteotomy of the first metacarpal can be performed as well.

- For type VI of the Buck-Gramcko classification, the surgical treatment typically consists of removing the additional mostly hypoplastic thumb(s). Further procedures of reconstruction of the triphalangeal thumb are performed according to the shape of the extra phalanx as described above.
