Please be aware that if 5GL-Doctor is not downloaded from our server or Altered States server then the database pointers are not set correctly and information in regards to diseases will be mixed up. There seems to be an awful lot of sites that are offering this software for download but even if such works, the database will be mixed up.

About 5GL-Doctor (sample displays follow)

The database is large. It is intended to be modified or enhanced by the user. Every medical condition is associated with a symptom/sign pattern. In response to an inquiry containing symptoms/signs, a mathematical technique is used to find the best matched patterns in the database. The techniques used are largely mathematical and take into consideration such factors as how common a condition is or what is the probability of two symptoms appearing in a condition. Another analysis function can process lab results. Another finds "similar conditions". Another function allows less exact symptom/signs in the inquiry. Another continually removes randomly a symptom/sign and shows what the short lists would look like without a particular symptom/sign. You can set options to narrow the focus of the search. Below are examples. The actual symptom/sign selection list contains about 9000 specific items most of which are alternate descriptions or medical names. There are analysis functions which do not need such specific names. A log is available that explains which expert system process contributed what weight (to a particular entry on the short list) and for what reason.

Did you know? Medscape regularly has case studies and collects statistics as to how often physicians get the test case diagnosis right. In more complex cases, it seems a typical physician has only a 30% chance of getting the correct diagnosis. While we don't know exactly if it is medical students or experienced doctors who tackle these test cases, what is clear is that an in-depth knowledge of medicine is required to do so.

Physicians are often busy people. All it takes is one lapse to even loose a career. Software such as 5GL-Doctor may just save such a lapse because it is extremely highly accurate in its production of the short lists. If a physician is about to make a final diagnosis but 5GL-Doctor does not display such on the top 10, then either the database is missing something or a symptom/sign pattern is incorrect or the physician is wrong. It is lovely to read how an expert in medicine came to a conclusion - but there are not that many experts in some conditions. (e.g. Lyme disease). [on this score, in the description of a medical condition the database often includes known legal-medical "pitfalls" especially relevant to the USA legal system. Sometimes the database contains extracts from articles which medical experts considered important for physicians to be aware of in respect of a particular condition].

One of the earliest successes (by 2011 5GL-Doctor has been around for some 15 years) was a physician from a former Eastern block country. He had a patient with neurological symptoms he could not pin-point. He purchased 5GL-Doctor out of curiousity as to what it would come up with - ah, but at the top of the short list was the exact condition that subsequently a specialist diagnosed! (5GL-Doctor listed a number of rarer complex neurological conditions and the reason this physician decided to refer the patient to a special neurologist - to refer a patient to an expert is not as simple in some former Eastern block countries as it is in Western countries because sometimes the expert is not in that country and a Visa and even a medical invitation may be required. Thus physicians in some countries want to be very certain before making such referrals.) Another success was when 5GL-Doctor correctly identified Lyme Disease for a patient in Britain who had been sent around for 3 years to different specialists none of which made the correct diagnosis until a University expert was asked to assist. If the symptoms/signs are correct, and laboratory results are consistent, then unless a particular disease and/or combination is missing from the database or the symptom/sign pattern has been defined poorly, then the mathematics will always put the correct condition at the top of the short list. (around 4000 symptom/sign patterns but some contain up to 20 variations explained in the entry. As the software evolved, more and more of some ever so complex case studies from Medscape have been included. Thus the software may in fact find the "best fit" case study and place this on top of the short list instead of a name of a condition).

Three Main Function

1. Analysis/Diagnosis. Different analysis functions. The database has perhaps 4,000 medical conditions defined but some of these contain many variations. The database is completely updateable. The symptoms/signs/other items Selection List is simply too large to count easily, perhaps 9,000 items - aliases form automatically as the Compilation Matrix is built consequently the actual number of specific entries (e.g. symptoms, signs, etc.) defined is perhaps 4000 but this expands on the Selection Lists becauae of the aliases - in addition the software scans and picks up any symptom/sign/item not directly defined thus the total Selection List is probably around 9,000 to 10,000 items?

2. Medical Information Storage and Management. Comes with populated drugs database, medical procedures database, laboratory tests database. Image library and databank are not populated but contain entries that serve as demonstration of how the two features can be used.

3. Execution of Conversations which can be a system review or a medical algorithm or even questions and answers that a person could go through while waiting in the surgey. Comversations can be designed by the user. About a hundred are provided, including a complete system review, as examples of how to write a conversation.

(note that the display size adjusts to suit a computer display - some of the displays herein have been reduced to make the images smaller on this web page - but some display are very large on larger displays).

There is also a large image library, however, this is more for the personal edition user. Some parts of the software are shared with the personal edition and some images included are very basic intended to educate the typical person. However, there are also some images which any physician might find useful such as of certain skin conditions. The image library was left asis because it was found that people with a more serious condition but who were not medical people tended to purchase the professional edition. Thus it was thought vital to leave some basic anatomical diagrams in place even in the professional editions.

Below is a sample of the databank - it is not populated as such, just some sample entries. You can use the databank to save your medical articles. Note that most of the headers below are set by you.
