This article takes about a patch that is applied to the skin, stays on all day, and delivers medication for ADHA in increments throughout the day. This has been done before with non-prescription different medications such as ibuprofin. However, it has not been done with a drug of this nature before. This patch helps children, who often have difficulty swallowing pills, get the medication they desperately need. With something like this possible, it is not that far off to think that a patch similar to this, that delivers insulin to diabetics can be accomplished.

This study speaks to the benefits and complications associated with transdermal drug delivery, specifically with ibuprofen. It talks about why transdermal delivery is effective, and how it works. They also mention that it is a method that is becoming increasingly popular, because in some cases people have difficulty swallowing large pills. Some of the complications include the skin’s natural chemical barriers that sometimes make it difficult for the drugs to get through to the bloodstream.

In this study they experimented with using microneedles in transdermal patches. In doing this they eliminate some of the complications with some patches not being able to deliver an effective drug through the skin’s chemical barriers. These patches can be applied easily by a patient, and are effective almost immediately. Patches like this, that use microneedles, are not currently available on the market, but the studies being done on them are very promising so far. If this same delivery method can be used for insulin delivery diabetics will be able to get the medication they need much easier, and those who are unable to inject themselves with their insulin dosages will no longer need help getting the medication they need.

Annotated Bibliography – Toe Splint

 

Borke, Jesse . “Broken toe – self-care.” MedlinePlus Medical Encyclopedia. Accessed October 19, 2017.

 

The MedlinePlus Medical Encyclopedia focuses mainly on broken toes. It goes into detail about the injury and what to expect and feel from the injury. They go on to tell you how long it will last and what are some symptom reliefs for it. One of the remedies provided is buddy wrapping. This is when you connect your inured toe to the adjacent toe using tape. This remedy gets annoying, unconfutable and doesn’t really prevent so much pain. This is why our group would like to use the toe splint. An easier and more convenient way.

 

 

Macmanus, Joseph E. “The use of a plaster slipper in the management of simple fractures of the toes.” The American Journal of Surgery 54, no. 3 (1941): 721-22.

 

Doctor Joseph Macmanus discusses a simple yet effective way to provide comfort and protection to a fractured toe. His remedy involves a plaster slipper. He describes how to wrap your foot and toe in plaster to keep it protected. It is like molding the plaster to your foot. This method while may be effective is also annoying to wear and hard to apply. The foot has to be bathed, dried and powdered. Measurements have to be taken and then plaster applied. The plaster is bulky and hard to wear with shoes. This is why our group would like to use the toe splint. An easier and more convenient way.

 

 

Singh, H.p., and N.d. Downing. “An “empty” toe.” The Foot 15, no. 2 (2005): 114-16.

 

Hp singh describes how a freak accident caused a patient to break her toe. Not only did it brake but it “went missing”. As to say the bone of the toe cam out of the toe skin socket and into a different skin socket. So one of the patients toe sockets was just empty skin without a bone. They did surgery on her and fixed her toe. She was then put in a plaster slipper. This is why our group would like to use the toe splint. An easier and more convenient way.

Pifer, G. 2000. “Casting and splinting: prevention of complications.” Topics In Emergency Medicine 22, no. 3: 48-54.  Accessed October 23, 2017.

In his article, “Casting and Splinting: Prevention of Complications,” Dr. Gerald Pifer, a professor of orthopaedics discusses the proper method of applying a cast or splint to an injured limb. This is a relatively short peer-reviewed article which includes the principles underlying the technical aspects of casting and splinting. Although Paul is already an expert at splinting, this article serves as a good source for Elina and I to understand the basics of splinting. This way, we can improve on the commonly used methods in our project.

The second article I found, “The Manchester short splint: A change to splinting practice in the rehabilitation of zone II flexor tendon repairs,” is by authors FH Peck, AE Roe, CY Ng, C Duff, DA McGrouther and VC Lees (the article does not indicate their positions, although presumable they are experts in hand therapy because that’s the journal that published their work). They discuss the benefits of using a “Manchester short splint” which is not as long as the regular forearm splint for certain types of tendon repairs. The benefit of using a shorter splint is that the wrist is able to move, which enables joint extension and flexion. This is a useful article for our project because by examining the structural and functional benefits of alternative splinting methods, proven to be safe, we may be able to adapt those methods in our design.

On the health and fitness website livestrong.com, Robin Gilbert posted: “What are the Different Types of Splints?” This is a basic overview on what type of splint would be used in a particular injury; for example, soft splints are an effective quick method to support the injured limb and offer comfort. Understanding the major types of splints is key so that we know the injuries our project splint should be targeting.

Suzanne Mintz is a family caregiver and she co-founded the Family Caregivers Association.  This peer-reviewed article discusses Suzanne’s struggle after breaking her toe and how the break negatively affected her ability to work.  She talked about how she felt as though her doctor was not able to provide her with much help.  She felt as though there was not much she could do about her unfortunate situation.  This source is helpful in recognizing that there is a problem with how broken toes are treated and that a solution must be found.

John W. Richards and David Govaker are both writers for the Journal of Family Practice and are discussing a new method for treating a broken toe.  They are suggesting that the current method of taping a toe to a neighboring toe can actually be detrimental for the fracture and cause greater amounts of pain than the toe would feel without the tape.  This source is valuable for my project because it shows that there are clear issues with the current method of healing broken toes and perhaps a new treatment could arise that will be better than the current one.

James Roland is a staff writer for Healthline who is discussing everything that goes into a broken toe.  He discusses all of the symptoms and treatments and talks about how there is not so much that a doctor can do about a broken toe.  He brought up the method of taping a toe to its neighbor as the primary treatment for a mild broken toe.  This article is helpful in showing that there really is only one common held method which is not the method that I am suggesting we create.  I believe that isolating the toe and placing it in a hard splint would be more beneficial for the healing process than taping the toe it to its neighbor and this article proves that my method has not been fully tried yet.

This article provides important background information regarding the development of Novel Drug Delivery Systems (NDDS); furthermore, the article outlines the various categories of NDDS and their respective medical applications. Relevant to our project, one of the categories discussed in detail is pharmacosomes (a type of liposomal drug delivery system). Specifically, the article explains the pharmacological features of pharmacosomes,  as well as the advantages and disadvantages of using them over other NDDS. For example, pharmacosomes are the preferable method of drug delivery because, through this method, the  drug is covalently linked; subsequently, loss due to leakage of drug, does not take place. Additionally, the article describes different methods for preparing pharmacosomes (e.g. injection method vs. hand-shaking method). This information is useful for our project because it aids in understanding how pharmacosomes function and provides evidence of their viability for the oral administration of anticancer drugs.

  • This peer-reviewed article was written by Dr. David R. Khan from the Department of Mathematics, Chemistry and Physics at West Texas A&M University and published in the Journal of Cancer Science and Therapy. This article outlines the use of nanocarriers (such as liposomes, pharmacosomes, etc.) for drug delivery in cancer therapy; more specifically, it discusses the advantages of nanocarriers and their propensity for success in targeted anticancer treatments, as well as addresses some of the obstacles associated with drug transfer to cancer cells, and achieving uniform drug distribution at the tumor site, amongst others. According to the article, two of the (arguably) most significant advantages of using nanocarriers for drug delivery are (1) they can improve the pharmacological properties of traditional chemotherapeutics, and (2) because of their small size, they are able to effectively deliver encapsulated anticancer drugs to tumor tissue–regardless of vascular defects commonly observed at tumor sites due to the formation of new blood vessels (angiogenesis). This article will be a useful resource for our project because it offers an in-depth explanation of nanocarriers’ functions and provides relevant examples of completed clinical trials demonstrating the success of nanocarriers for drug delivery in cancer therapy.

  • This online article published in The New York Times Magazine was not written by one individual; rather, it is comprised of condensed and edited responses from six New York Times readers detailing their personal experiences–good and bad–with new cancer treatments. The treatments mentioned in the article are as follows: crizotinib (an ALK inhibitor), PET scans to gauge individual responses to treatment, immunotherapy drugs, Atezolizumab (a monoclonal antibody), and olaparib (first PARP inhibitor approved for treatment of ovarian or breast cancer). While the article does not explicitly mention/ discuss liposomal drug delivery systems, it does well to show the many different kinds of therapies/ treatments that are being developed and used in the fight against cancer. Moreover, it highlights the difficulties patients often face when navigating and undergoing cancer treatment. This information could be used in our project as evidence of the need for new cancer treatments, especially treatments that are more targeted and less invasive.

This article studies how colonization of the mouth by the bacteria Candida differs with the presence of braces. They found that the Candida is present in greater amount when braces are also present in the mouth. This article proves there is a need for a more effective tool for brushing one’s teeth with braces. Candia is a bacterium that can cause unsightly and uncomfortable fungal growth in the mouth.

This article studied the effectiveness of electric toothbrush versus a regular toothbrush used by people with braces. It found that the mechanical toothbrush was more effective for people who in general have poor dental hygiene practices. This article has made me consider if creating an electrical design would be more effective.

This article was published in Volume 16, issue no. 2 of AAPS PharmSciTech, the peer-reviewed online journal of The American Association of Pharmaceutical Scientists. The journal publishes pharmaceutical news related to the research, development and evaluation of pharmaceutical dosage forms and delivery systems.

The text initially provides background on oral administration of medication, stating that it has long been preferred because it is non-invasive. The article then proceeds to discuss new research conducted for the development of new forms of pediatric medicines, while stating that the findings can be widely interpreted. The research referenced in this article mentions that increasing usage of orally disintegrating films and tablets, especially small-sized tablets may be appropriate for the administration of pediatric medicine, pending licensing and approval. Overall, enhancements to the administration of pediatric medicine are necessary, but only if they are subject to proper regulation and review.

This article was published in Volume 101, issue no. 7 of Archives of Disease in Childhood, an international peer review journal that aims to inform pediatricians about various advances in the diagnosis and treatment of childhood diseases.

The text discusses the current methods of oral ingestion of medication for newborns and infants, as well as the advantages and disadvantages of each. One trend the article points out is that there has been a general increase in the attention that is paid to the specific form that pediatric medication takes. Moreover, the older a child gets, the more tolerant that child becomes to larger tablets meant to dissolve in the stomach rather than the mouth. The study also found that there is evidence to suggest that children prefer mini-tablets rather than a powder, suspension or syrup. Lastly, the article discusses the potential for the administration of medicine through orodispersible films – a tablet designed to disintegrate in the patient’s mouth.

Gray’s article discusses the results of a series of tests taken with a sample size of 143 patients taking 283 pills. As background, the article mentioned two key figures; namely, that one in three people have difficulty swallowing oral medication, and that 10% of patients with swallowing difficulties cite this as a reason for not taking prescribed medication at all. Gray outlines the procedure of the study, and then proceeds to outline the two techniques that patients were asked to use to swallowing traditional medicine capsules: the “pop bottle method” and “lean forward method.” The study found that these techniques resulted in more pills successfully swallowed.
