Introduction:

Slipped Capital Femoral Epiphysis (SCFE) is a relatively rare but potentially serious hip disorder that mainly affects adolescents during their growth spurts. This condition occurs when the ball at the top of the thigh bone (femur) slips off the neck of the bone at the hip joint. Understanding SCFE is crucial for early detection and treatment to prevent long-term complications. In this article, we delve into the causes, symptoms, diagnosis, and treatment options for SCFE.

What Causes SCFE?

The exact cause of SCFE is not fully understood, but it is believed to be related to a combination of factors, including:

Growth spurts: SCFE often occurs during periods of rapid growth, typically in pre-adolescents and adolescents. The growth plate at the top of the femur is weaker during these growth spurts, making it more susceptible to slipping.

Obesity: Excess weight puts added pressure on the growth plate, increasing the risk of it slipping. Obese children are more likely to develop SCFE compared to those of normal weight.

Hormonal changes: Hormonal changes during puberty may also contribute to the weakening of the growth plate, making it more prone to slipping.

Genetics: There may be a genetic predisposition to SCFE, as it tends to run in families.

Symptoms of SCFE:

SCFE can present with various symptoms, which may include:

Hip or knee pain: Persistent pain in the hip, groin, thigh, or knee, particularly during physical activity, is a common symptom of SCFE.

Limping: A noticeable limp or inability to bear weight on the affected leg may occur due to pain and instability in the hip joint.

Limited range of motion: Reduced flexibility and range of motion in the hip joint may be observed, making it difficult to perform certain movements.

Outward rotation of the leg: The affected leg may appear to turn outward due to the displacement of the femoral head.

Diagnosis of SCFE:

Diagnosing SCFE typically involves a combination of medical history review, physical examination, and imaging tests. The healthcare provider will inquire about the child's symptoms and perform a physical examination to assess the range of motion and stability of the hip joint.

Imaging tests are essential for confirming the diagnosis and determining the severity of the condition. X-rays are commonly used to visualize the position of the femoral head relative to the femoral neck. In SCFE, characteristic findings on x-rays include a slippage of the femoral head in relation to the neck, often described as a "ice cream slipping off a cone" appearance.

In some cases, additional imaging studies such as MRI or CT scans may be ordered to obtain more detailed images of the hip joint and surrounding structures.

Treatment Options for SCFE:

The primary goals of treatment for SCFE are to stabilize the hip joint, relieve symptoms, and prevent further slippage. The treatment approach may vary depending on the severity of the condition and the child's age and overall health. Common treatment options include:

Surgical intervention: In most cases of SCFE, surgery is necessary to stabilize the hip joint and prevent further slippage. The two main surgical procedures used to treat SCFE are: a. In Situ Fixation: This involves inserting screws or pins into the femoral head and neck to hold them in place and prevent further slippage. b. Realignment Osteotomy: In severe cases or when the slip is chronic, a realignment osteotomy may be performed to reposition the femoral head and neck into the correct alignment.

Non-surgical management: In some mild cases of SCFE, non-surgical measures such as rest, activity modification, and physical therapy may be recommended to alleviate symptoms and prevent worsening of the condition. However, close monitoring is essential to detect any progression of the slip.

Post-operative Care and Rehabilitation:

Following surgery, a period of immobilization and restricted weight-bearing may be necessary to allow the hip joint to heal properly. Physical therapy is an integral part of rehabilitation to improve strength, flexibility, and mobility of the hip joint. The rehabilitation process is tailored to each individual's needs and may continue for several months to achieve optimal recovery.

Long-term Outlook:

With prompt diagnosis and appropriate treatment, most children with SCFE can expect favorable outcomes and return to normal activities. However, untreated or poorly managed SCFE can lead to serious complications such as hip joint deformity, osteoarthritis, and chronic pain later in life. Regular follow-up appointments and monitoring are essential to detect any signs of recurrence or complications early on.

Conclusion:

Supercritical fluid extraction (SCFE) is a broadly used process to obtain specific compounds (called target molecules or simply products) from plant based raw materials. Following are some of the other processes used for extraction:

Hydrodistillation & Steam Distillation

Solvent Extraction

Microwave-assisted Extraction

Mechanical Pressing

Ultrasound-assisted Extraction

Detente Instantanee Controlee (DIC)

Hydrodistillation boils the solution with the dissolved raw material. Different products from the raw material boil off at different temperatures and are separately collected on condensation at these respective different temperatures. A variant of hydrodistillation is steam distillation. Both use heat and therefore can alter the chemical structure of the product. This lowers extraction purity.

Flavours and fragrances extracted using supercritical fluid extraction (SCFE), for example, are more similar to the original product than those obtained via hydro or steam distillation.

Solvent extraction uses solvents such as hexane, acetone and others to obtain the products. The solvent first dissolves the product from the raw material. Thereafter, the solvent and product are separated to obtain the product. The solvent does not completely separate from the product i.e. there is some contamination. Again, this affects the purity of extraction.

Apart from purity, another issue with solvent extraction is the lack of selectivity. When extracting astaxanthin from microalgae, solvent extraction using hexane or acetone provided lower yields. This is because these solvents cannot differentiate between astaxanthin and the astaxanthin-lipid combine. Using supercritical fluid extraction (SCFE) for the same purpose delivers more than double the yields as obtained from solvent extraction.

Properties of the supercritical fluid (SCF) best explain the plus points of supercritical fluid extraction (SCFE). An SCF is a fluid with its:

Pressure above its critical pressure; and

Temperature more than its critical temperature.

In the state, the SCF’s properties can:

Be similar to that it its liquid state;

Resemble those of its gaseous phase; or

Be a mix of these two phases.

Changing the pressure alters the solvent power of the SCF. Solvent power is the capacity of the SCF to dissolve a product from the raw material. At a certain pressure, the SCF dissolves one particular product from the raw material. Few if any of the other products get dissolved and those too in minimal quantities.

Pressure control is among the most important parameters of the supercritical fluid extraction (SCFE) process, if not the most important. This is because the accuracy of the SCFE system in India and elsewhere depends on it. And, accuracy is the reason why many opt for supercritical extraction in India or the rest of the world.

Supercritical fluid extraction (SCFE) uses a supercritical fluid i.e. a fluid that has its:

Pressure more than its critical pressure; and

Temperature above its critical temperature.

In this state, its solvent power i.e. its capacity to dissolve the required product from the raw material depends largely on pressure. An SCF’s solvent power is:

High at elevated pressures; and

Low at smaller pressures.

Most importantly, the SCF will dissolve (or extract):

One particular product from the raw material at one particular pressure.

Very little or no quantities of other products at this pressure.

This is precisely at the root of the accuracy of supercritical extraction in India and other countries. SCFE systems in India and elsewhere are therefore built to have extremely close pressure control.

Speaking of pressure control in supercritical fluid extraction (SCFE), managing the pressure drop between the extractor and the separator is a delicate operation:

Extractor operates at high pressure and is where the SCF dissolves the required product from the raw material.

Separator operates at low pressure and is the location where the SCF throws the product out of solution.

If the SCFE system in India, or anywhere else for that matter, allows free pressure drop between the extractor and the separator, the SCF will freeze and form ice inside the SCFE piping. This will interrupt the process and cause unnecessary downtime. This happens in sync with the Joules Thompson Principle and can occur in all set ups, whether supercritical extraction in India or in the rest of the world.

According to the said principle, the temperature of a fluid falls drastically if it is allowed to expand freely without:

Performing external work; or

Heat addition.

SCFE systems in India and other places therefore use back pressure regulation valves to achieve a gradual and steady pressure reduction of the SCF to prevent ice formation.

Following features improve the utility of a supercritical fluid extraction system- in addition to pressure, temperature, and flow control - that is in addition to pressure, temperature, and flow rate:

● Co-solvent Pump

● Automation

● Intuitive User Interface

● Ergonomics

SCFE, also called supercritical extraction, uses a supercritical fluid (SCF) for the purpose of separating the required compound (called target molecule). An SCF is one that is at a :

● Pressure above its critical pressure; and

● Temperature above its critical temperature.

In the supercritical state, the solvent power of the fluid depends on its pressure. Solvent power is the capacity to dissolve the required target molecule. Solvent power of the supercritical fluid rises with pressure and vice versa. The same is true of the relationship between its solvent power and temperature.

More importantly, at a set pressure (and / or temperature), the SCF will dissolve only one particular target molecule while leaving other compounds in the raw material relatively untouched. This has a direct bearing on the accuracy of the process, and this is the reason why pressure and temperature control are so crucial to the success of supercritical extraction.

Flow control is important because it controls the amount of time the supercritical fluid will be in touch with the raw material. It has a direct impact on the yield, efficiency, and mass transfer rate.

Let us now consider the other factors:

● Co-solvent Pump: Is a useful addition to the SCFE setup for diversifying the compounds that can be extracted. It adds a co-solvent to the supercritical fluid in the required proportion.

Take the case of SCFE using carbon dioxide (CO2) i.e. CO2 SCFE. Supercritical carbon dioxide (sCO2) is good at isolating non-polar compounds from raw materials. Addition of co-solvents such as ethanol, water, and methanol in minor quantities makes it capable of extracting polar compounds as well.

● Automation: Ensures the error free operation of supercritical extraction, or any other engineering system for that matter. During the addition of co-solvent via the co-solvent pump for example, automation mixes it in the required proportion.

Top SCFE equipment manufacturers use rapid extractor changeover valves to minimize downtime, something that automation makes possible.

These are just a couple of examples. The benefits of automation extend across the entire installation in the form of greater productivity, efficiency, and safety. Extractors in the SCFE set up operate at higher pressure and separators at lower pressure. Pressure control and change is absolutely necessary for the success of extraction - something which automation deals with effortlessly.

● Intuitive User Interface: Helps the operator better understand the process flow. This way, the operator is at ease when in front of the interface. Please note, setups have their own design and workflow. Grasping their nitty gritty is essential to monitor and control them in an improved manner.

Flavours find application in the beverages, bakery, confectionary, dairy, and convenience foods industry. Fragrances are employed by the cosmetics, toiletries, soaps, detergents, and fine fragrance businesses.

User preferences over the world are shifting in favour of products with pure and natural ingredients. Extraction of flavours with the carbon dioxide (CO2) supercritical fluid extraction (SCFE) process preserves the purity of the extracted molecule. It is for this reason that the process is preferred in flavour and fragrance extraction.

There are more than 250 species of plants from which over 500 natural raw materials are extracted for the flavours and fragrances industry. Among the most in-demand flavours and fragrances are rose oil, tuberose absolute, angelica root oil, jasmine absolute, ambrette seed oil, and orange flavour oil.

On the global scale, the flavours and fragrances market is forecasted to grow at a CAGR of 4.3% from 2019 onwards and reach $36.6 billion by 2024. Natural ingredients are widely regarded as safer and healthier. The demand for natural ingredients in products is an important factor expected to propel the market to greater and greater heights. The dairy and beverage industry is increasingly resorting to the utilization of biotic elements. Flavours are also finding increasing application in the dietary supplement, pharmaceutical, and nutraceutical businesses. And with expanding disposable incomes, customers are more than willing to spend extra for these natural products.

Heating a fluid to above its critical temperature and hiking its pressure to more than its critical pressure takes it to the supercritical stage. Properties of a supercritical fluid (SCFE) are very peculiar in that they can be similar to that of a liquid, a gas, or somewhere in between these two states. For example, its density is higher as that of a liquid. Solvent power is directly proportional to density. However, its surface tension and viscosity is low, similar to that of a gas. This helps it penetrate deeper inside porous raw material.

An interesting point about the density and solvent power of SCFs is that they can be controlled through minor changes in pressure and temperature. By precisely adjusting the pressure, the SCF can be made to extract one particular target molecule with little or no inclusiont of other molecules. In short, SCFE extracts molecules in their relatively pure form - exactly what the market is asking for.

Conducting SCFE with carbon dioxide (CO2) i.e. CO2 SCFE adds another layer of benefits. CO2 has a low critical temperature of 31.1 deg-Celsius. Therefore, CO2 SCFE process temperatures for flavour and fragrance extraction is not very high. This prevents the thermal degradation of the target molecule, transforming into better purity. Then again, the critical pressure of CO2 is 73.9 bar. This is not very high and, again, requires the use of not very high process pressure.
