New AI model may accurately diagnose periodontal bone loss and periodontitis from dental panoramic radiographs: Study

A new AI model may accurately diagnose periodontal bone loss and periodontitis from dental panoramic radiographs suggests a study published in the Journal of Dentistry.

Artificial intelligence (AI) could be used as an automatically diagnosis method for dental disease due to its accuracy and efficiency. This research proposed a novel convolutional neural network (CNN)-based deep learning (DL) ensemble model for tooth position detection, tooth outline segmentation, tooth tissue segmentation, periodontal bone loss and periodontitis stage prediction using dental panoramic radiographs. The dental panoramic radiographs of 320 patients during the period January 2020 to December 2023 were collected in our dataset. All images were de-identified without private information. In total, 8462 teeth were included. The algorithms that DL ensemble model adopted include YOLOv8, Mask R-CNN, and TransUNet. The prediction results of DL method were compared with diagnosis of periodontists.Results: The periodontal bone loss degree deviation between the DL method and ground truth drawn by the three periodontists was 5.28%. The overall PCC value of the DL method and the periodontists’ diagnoses was 0.832 (P <​ 0.001). ​The ICC value was 0.806 (P <​ 0.001). The total diagnostic accuracy of the DL method was 89.45%.The proposed DL ensemble model in this study shows high accuracy and efficiency in radiographic detection and a valuable adjunct to periodontal diagnosis. The method has strong potential to enhance clinical professional performance and build more efficient dental health services. The DL method not only could help dentists for rapid and accurate auxiliary diagnosis and prevent medical negligence, but also could be used as a useful learning resource for inexperienced dentists and dental students.

Study Finds U-Shaped Link Between TyG-BMI and Mortality Risks in Osteoarthritis Patients, Highlighting IR Role

China: A recent analysis of National Health and Nutrition Examination Survey (NHANES) data from 1999 to 2020 has unveiled a U-shaped nonlinear relationship between the triglyceride glucose-body mass index (TyG-BMI) and both all-cause and cardiovascular mortality among adults with osteoarthritis (OA) in the United States.

The findings, published in Scientific Reports, highlight the complex role that insulin resistance (IR) plays in the health outcomes of these patients.

“Mortality risks escalated when TyG-BMI levels exceeded thresholds of 282 for all-cause mortality and 270 for cardiovascular mortality. For each 10-unit increase above these thresholds, there was a corresponding 3% rise in the risk of all-cause mortality and a 5% increase in cardiovascular mortality risk,” the researchers reported.

The TyG-BMI index, a composite measure combining triglyceride levels, glucose levels, and body mass index, has been increasingly recognized for its potential in assessing metabolic health and the risk of adverse outcomes. The relationship between insulin resistance and all-cause and cardiovascular mortality risk in osteoarthritis patients is still unclear. Considering this, Wenbo Ding, China Medical University, Liaoning, People’s Republic of China, and colleagues aimed to clarify the correlation between a novel marker of IR, the TyG-BMI index, and the risk of all-cause mortality and cardiovascular mortality in OA patients.

For this purpose, the researchers analyzed data from the NHANES covering 1999 to 2020. They used multivariable Cox proportional hazards regression analysis and restricted cubic spline plots to investigate the relationship between the TyG-BMI index and all-cause and cardiovascular mortality risk among osteoarthritis patients. To further refine their findings, subgroup analyses were performed to examine potential interactions and identify populations at higher mortality risk.

The study included a cohort of 4,097 OA patients who were followed for 20 years, during which 1,197 cases of all-cause mortality and 329 cases of cardiovascular mortality were documented.

The following were the key findings of the study:

  • There was a U-shaped nonlinear relationship between the TyG-BMI index and the risk of all-cause mortality or cardiovascular mortality in OA patients, with the lowest mortality risk thresholds identified at 282 and 270, respectively.
  • Surpassing these thresholds was associated with a 3% increase in the risk of all-cause mortality and a 5% increase in the risk of cardiovascular mortality for every 10-unit increment in TyG-BMI level.

The study reveals a U-shaped nonlinear relationship between TyG-BMI levels and all-cause and cardiovascular mortality in osteoarthritis (OA) patients, identifying a specific TyG-BMI index threshold associated with the lowest mortality risk. This finding offers clinicians a new perspective and potential intervention target for identifying and addressing OA patients at higher mortality risk.

“The research highlights the value of the TyG-BMI index in assessing insulin resistance (IR) to predict OA patient outcomes and suggests that insulin therapy could benefit these patients,” the researchers concluded.

Premature newborn’s hand amputated due to negligence! Hospital, Doctor slapped Rs 45 Lakh Compensation

Amritsar: The District Consumer Disputes Redressal Commission, Amritsar recently directed a city-based private hospital and its doctor to pay Rs 45 lakh compensation and Rs 1 Lakh legal cost to a man for alleged medical negligence while providing treatment to his newborn child.

After being born prematurely, the child was admitted to the hospital as he was suffering from a low oxygen level. However, during treatment, gangrene formed in his right hand leading to the amputation of the hand at PGI Chandigarh.

The history of the case goes back to 2020 when the complainant’s son was born. At the time of birth, his oxygen level was very low and accordingly, the newborn was admitted to the treating hospital on 22.08.2020.

As per the complainant, during the medical treatment of the newborn, the treating doctors put the wrong drip on his right hand due to which his hand became blue. Consequently, the child’s right arm became damaged due to impending gangrene and alleged wrongful treatment provided by the treating hospital and doctors. 

It was alleged that after being admitted to the hospital for some days, the newborn was arbitrarily discharged. Following this, he was admitted to PGI Chandigarh, where after proper diagnosis, his right hand was amputated by the treating doctors of PGI Chandigarh in order to save his life.

Alleging medical negligence on the part of the treating doctor and hospital, the complainant sought Rs 45 lacs compensation, and Rs 2 lacs as litigation expenses.

On the other hand, the doctor and hospital argued that the complainant did not explain how they were negligent in providing treatment to the minor child. According to them, no medical expert was examined to prove that they were negligent in the treatment provided to the complainant’s son.

As per the doctor and hospital, the child was put on ventilator support and oxygen for altogether 15 days and showed improvement and started digesting feeds. However, since the child was pre-term with very low immunity, he developed sepsis for which he was being given the required antibiotics. On the 20th day of admission, the child’s condition suddenly deteriorated and the attendants were informed and advised to take the baby to a centre for further investigations and treatment of the hand. Accordingly, the treating doctor talked to the Paediatric Intensivist at Fortis Hospital for immediate care of the child, but the attendants acted negligently and refused to take the child to Fortis Hospital and insisted on continuing the treatment from the treating hospital only. Again, the attendants were suggested to take the baby to Fortis or PGI Chandigarh or any other higher institute of their choice, they submitted.

It was submitted that the child was initially taken to another hospital, where no proper facilities were available and was taken to PGI Chandigarh only after a delay of a few days.

Delay in getting the appropriate treatment to prevent the loss of hand was due to sheer negligence of parents and other family members who did not take their baby directly to Fortis Hospital or PGI as per medical advice given by them, argued the treating doctor and hospital.

While considering the matter, the District Consumer Court took note of the report by the Asstt. Civil Surgeon, Amritsar dated 09.07.2021, which stated, “In conclusion the medical board has given its opinion that the aforesaid complication was caused due to inadvertently and Dr. *** has promised that when the child grown up he will get arrangement of artificial limb/hand.”

Referring to this report, the Commission observed, “So a bare reading of the report given by Medical board, it stands proved that the opposite parties No.1 & 2 ( the hospital and the doctor) have admitted their fault and only given explanation that the whole episode done due to inadvertently. So all amounts to negligence which has been analysed in Halsbury’s Laws of England (4th Edition) Volume 34…”

“So far as medical negligence is concerned it was the duty of the medical professionalists to take due care while treating the patient much less the patient is of a tender age. It is admitted that patient was referred to them as it was a premature delivery of the child and this child was required utmost care which as per allegations of the complainant the opposite parties have failed to provide to the minor son of the complainant. Heavy onus is upon the hospital when it alleges that they are not negligent to give treatment to the son of the complainant and to prove that they have discharged their duty with due care,” it further noted.

Relying on the legal precedence set by the Supreme Court regarding issues concerning medical negligence, the District Consumer Court Amritsar held the treating hospital and doctor guilty of negligence in providing treatment to the complainant’s son.

In respect to the amount of compensation, the Commission held that the compensation demanded by the Complainant i.e. Rs 45 lacs was “very very less than the mental agony whatsoever the complainant and his family suffered at the hands of the opposite parties and the minor son of the complainant become handicapped due to the negligence of the opposite parties and his present as well as future life is also affected due to the act of the opposite parties.”

Accordingly, the Commission ordered, “Hence, the opposite parties No.1 & 2 are directed to pay compensation of Rs. 45 lacs and Rs. 1,00,000/- as litigation expenses to the complainant. It is also ordered that since the welfare of the child is involved in the present case and keeping in view the peculiar circumstances of the case, the entire amount of Rs. 45 lacs as compensation and Rs. 1,00,000/- as litigation expenses which is to be given to the complainant being the guardian of the minor child and he will convert the same into the FDR in the name of the minor son of the complainant till he attains age of 21 years.”

DCI issues advisory for dental colleges on uploading details of BDS, MDS, PG Diploma admissions

New Delhi: Through a recent notice, the Dental Council of India (DCI) has released an advisory for dental colleges regarding admissions to BDS /MDS/ PG Diploma Courses.

In the advisory to the Principal/Head of all the Dental Colleges, the Executive Committee of the DCI referred to its observation and stated that in its meeting held on 21.09.2024 has observed that there have been instances, where colleges prematurely upload the details of the students on the DCI portal without completing the actual admission process at their college OR when such student is actually admitted in some other dental colleges, which not only leads to distress the students but also creates confusion for the DCI and for the colleges where the students are genuinely enrolled.

The Executive Committee has also observed that in case of cancellation/discontinuation of course by a student, the college is not informing to the Council timely to delete his/her name from the DCI portal, the council said.

Accordingly,  in order to combat with the problems being faced by the concerned students, colleges and the DCI, it has been decided as under:-

All the dental colleges in the country be directed to upload the details of only the bonafide student on DCI portal after verifying the eligibility and selection criteria prescribed in DCI regulations including

(i) valid allotment letter issued by the concerned counseling authority

(ii) valid fee receipt issued by the concerned college and

(iii) consent of admission by the student on judicial stamp paper, failing which the DCI shall take necessary action against the college as per norms.

It further mentioned, ” all the dental colleges be also directed to intimate this Council within 15 days about cancellation/discontinuation/discharge of any student from the college, failing which, appropriate action shall be taken under the provision of Dentists Act and Regulations made there under”

The above decision of the Executive Committee is communicated for information and strictly compliance.

ADHD: Misunderstood, underdiagnosed—and treatable

One in nine children in the U.S. have been diagnosed with attention-deficit/hyperactivity disorder, according to data released in May by the Centers for Disease Control and Prevention. More than 8% of college students have ADHD, too, and they often struggle in silence: distracted in lectures, unable to complete assignments on time, slow to make friends. The condition can even cause them to forget to take the ADHD meds that would help them.
