ICCD of AOI At Nangia

Nagpur, 23rd May 2024 – The Intensivist and Critical Care team of American Oncology Institute (AOI) at Nangia Specialty Hospital in Nagpur successfully treated a 34-year-old male patient who suffered a severe burn injury. The patient arrived at AOI Nagpur with accidental burn injuries affecting his face and torso (chest and abdomen areas), covering a total of 45% of his body surface area (BSA).

Upon admission, he presented with respiratory distress and hypotension, requiring immediate intervention in the isolation ICU. Under the expert care of the medical team, the patient underwent aggressive fluid therapy and pain management, initially responding well. However, his condition later deteriorated, leading to bloodstream infection and septic shock, accompanied by acute kidney injury.

Dr Amol Parate, Intensivist and Critical Care Specialist, AOI Nagpur, commented, “The successful treatment and recovery of this patient highlights the dedication and expertise of our medical team. Burn injuries pose significant risks to patients, including complications such as infections, septic shock, and organ failure. Despite encountering numerous hurdles along the way, our team remained steadfast in our commitment to providing the highest standard of care. Through diligent monitoring and tailored treatment plans, we were able to navigate these challenges and achieve a positive outcome for the patient.”

Dr Hrushikesh Phate, Facility Director, AOI Nangia Specialty Hospital, Nagpur mentioned, “Behind every successful clinical outcome lies the synergy of expertise and empathy, a testament to the collaborative efforts of our medical team. Our medical team, with their expert skills and empathetic approach, navigated the complexities of treatment with precision and care. They provided not only medical intervention but also emotional support, ensuring our patient felt valued and supported throughout their recovery. The successful outcome for this patient exemplifies our steadfast dedication to delivering superior healthcare services and underscores the transformative power of compassion in healing.”

Dr Amit Dhawan, Regional Chief Operating Officer, AOI Central Region, stated, “At AOI, we pride ourselves on our ability to handle even the most challenging medical situations. We are equipped with cutting-edge technology and experienced staff who are trained to manage and treat complications associated with burn injuries. We are committed to delivering exceptional care to our patients.”

In response to culture and sensitivity reports, antibiotics were escalated, leading to improved blood pressure and stabilization of kidney function after a 7-day course of treatment. Throughout his hospitalization, the patient underwent multiple debridement (removal of damaged or dead tissue from a wound) procedures and dressing changes to manage the burn wounds. Despite these challenges, he experienced another setback with the development of septic shock caused by a multidrug-resistant organism. Antibiotics were adjusted to polymyxin therapy, supported by vasopressors, resulting in significant improvement in the patient’s vital signs. After undergoing skin grafting and enduring a two-month hospital stay, the patient was discharged in stable condition, marking a remarkable milestone in his recovery journey.

TRIGEMINAL NEURALGIA- THE SUICIDE DISEASE A brief synopsis by Dr Vivek Loomba

New Delhi, 23rd  May 2024: The pain of Trigeminal Neuralgia is so intense that it is often called the “suicide disease”, as it can lead one to contemplate suicide.

Dr Vivek Loomba,

According to Dr Vivek Loomba, Consultant Pain Physician at the Indian Spinal Injuries Centre, New Delhi, “Trigeminal neuralgia, also known as tic douloureux, induces intense facial pain on either side of the face. The pain is nearly constant and so severe that routine tasks such as washing, touching the face, or chewing become challenging.”

When 70-year-old Devi (name changed) from Mizoram and 50-year-old Tania (name changed) from Thailand came to meet Dr. Vivek Loomba, they were having excruciating facial pain. Both of them had stopped eating solid food because of the intense pain. As a result of decreased oral intake, Devi had lost almost 4kg in a month. Both of them were diagnosed with a painful, chronic condition called TRIGEMINAL NEURALGIA- THE “SUICIDE DISEASE”.

Throwing light on the treatment of these patients, Dr Vivek Loomba said, “After clinical examination, MRI of the brain was done to look for any intracranial abnormalities. In most cases, MRI is normal, and these patients were no different. They had been taking painkillers and other medications for a long time. So after discussion with patients and their families, we decided to go ahead with the interventional procedure”.

Based on his evaluation, Dr Loomba recommended a trigeminal nerve block for Tania and radiofrequency ablation of the trigeminal nerve for Devi.

For this procedure, a needle is inserted from the affected side of the face until it reaches the specific nerve to be blocked. The procedure is performed under X-ray visualization to ensure accurate needle placement. A local anesthetic and steroid mixture is injected for the nerve block. However, during radiofrequency ablation, small electric impulses are delivered to destroy the sensory nerve fibers, resulting in pain relief. These procedures typically provide effective relief lasting 1 to 1.5 years, and sometimes even longer. If the pain recurs, the procedure can be repeated.

According to Devi, “I was suffering from facial pain for almost 6 months. It made my life terrible because I was barely able to eat, speak to my family or even live a normal life. The pain was so severe and intense that it felt like electric shocks and even painkillers were ineffective”.

Dr. Vivek Loomba further added, “Trigeminal neuralgia can affect individuals of any age, but it occurs more frequently in women aged 50 and above. This condition significantly impacts a patient’s life both physically and mentally. It is also associated with higher rates of depression, anxiety, and sleep disorders.”

Bollywood star Salman Khan also suffered from this painful facial nerve disorder for almost 7 yrs and underwent treatment in the US. When he opened up about his problem, he mentioned that at one point he himself felt suicidal.

According to Tania, “I came all the way from Thailand to India to meet Dr. Vivek Loomba because I was not getting any relief from the medications I was taking. Due to the pain, I stopped going to the office and interacting with my family and friends. But I am grateful to Dr. Vivek Loomba that he saved my life by treating this chronic pain condition”.

JV Ventures launches The Medical Centre (TMC), a bespoke healthcare-dedicated infrastructure platform

Hyderabad,22nd May 2024: JV Ventures, an investment management firm with a focus on value-added infrastructure, today announced the launch of The Medical Centre (TMC). TMC is a holistic real estate solution that will create the best-in-class healthcare facility by bringing together convenient end-to-end medical services and integrated wellness under one roof. The first TMC centre with be operational at HITECH City in Hyderabad.

JV Ventures has already established two path-breaking, differentiated platforms in education and life sciences with a combined portfolio of USD 500 million. While the flagship centre opens in the city in another six months, TMC will endeavour to open 75 centres across key cities including Bengaluru and Pune in the next 5 years with a target investment of USD 600 million.

Raja Jain was appointed as the CEO of TMC. Raja comes with over 20 years of experience including over a decade in the development and leasing of commercial and retail assets. His last assignment as Vice President of mall Management and Centre Head for Jio World Drive, Mumbai was a category creator in its own right. Before that, Raja served in senior management positions at Makers Group, CBRE, and Inox Leisure Limited.

TMC centres are ideally located near residential neighbourhoods offering patients easy access to healthcare services with best-in-class experience. These centres are multi-tenanted facilities that bring speciality clinics, physicians, diagnostics and pharmacies under one roof.

At the same time, they provide an opportunity for doctors and clinics to lease purpose-built medical facilities that save upfront investments in infrastructure. Each centre is designed to be code-compliant and with amenities like stretcher lifts, ample parking, wheelchair access, and professionally managed facilities. TMC platform also undertakes built-to-suit for hospital chains, offering a unique proposition to increase their footprint in new locations in alignment with their asset-light approach to expansion.

Beyond real estate, TMC is also complemented with two offerings – The Specialist and Prescriptions – that help doctors become entrepreneurs. The Specialist offers a medical co-working space for doctors with flexible leasing models. These fully furnished, experiential spaces within medical centres are complemented with trained support staff and facility management services that minimize administrative burdens and costs for doctors. In parallel, patients get hassle-free access to multi-specialists saving time on medical appointments. Through its digital community platform, The Specialist also gives member doctors an avenue to create awareness on specific topics that benefit patients, at large.

Prescriptions is the venture capital arm that provides access to funding for doctors to take up entrepreneurship. Through its pool of funds raised from angel investors, family offices and high net-worth individuals, Prescriptions offers equity-linked investments to young medical professionals looking to establish themselves as independent practitioners.

Elaborating on the concept, Vishal Goel, co-founder of JV Ventures, shared, “India is likely to witness an exponential growth in demand of hospital beds for in-patient services that may grow at a CAGR of 4.8% to reach 3.57 million by 2033. Fuelled by limited public investment, this demand would increase the per capita availability of hospital beds from 1.6 per 1000 in 2023 to 2.4 in 2033. In light of the burgeoning healthcare needs in India, there is a shortage of purpose-built infrastructure and an ecosystem that promotes medical entrepreneurship. We believe the TMC platform, with its multi-pronged approach will be a game-changer that will redefine how healthcare services are provided”.

Jasmeet Singh Chhabra, co-founder, of JV Ventures commented, “The addition of TMC to our portfolio is a testament to our efforts to invest and develop socially relevant infrastructure with community at its core. In addition to that, it warrants our investment partners’ favourable returns given the rising demand for such centres which is expected to double in the next decade.”

“I am excited about the overall impact of our endeavour with this platform”, said Raja Jain, CEO of The Medical Centre. “This is a great opportunity to develop a unique, first-of-its-kind offering in India. Our first centre of about 35,000 sq ft is in HITEC City, a prominent IT and residential hub in Hyderabad and we look forward to expanding our footprint to Bengaluru, Pune, and other major cities.”

The Indian healthcare industry is experiencing a profound transformation, fuelled by a convergence of economic, social, and policy factors. Healthcare expenditure is projected to grow at a compound annual growth rate (CAGR) of 15-17%, reaching an impressive INR 7.67 trillion by fiscal 2025. In 2023, India accounted for over USD 4.6 billion of the total USD 14 billion private equity investments in the healthcare segment in Asia Pacific region.

In light of the momentum gathered by healthcare in India, innovative business models amongst healthcare providers are emerging to bring in operational efficiencies. There has been a shift from in-patient services in hospitals to out-patient services in specialized centres, specifically for cardiac ailments, diabetes, eye-care, and birthing centres: The demands for specialized medical centres for out-patient services is expected to double in the next decade to a real estate value of over USD 1 billion. Moreover, the top 25 Indian cities are estimated to have a demand of about 15 million sq ft of medical centres by 2033, a staggering 10% of the total out-patient demand projected across the country.

Fibroids – Do all Fibroids Need to be Removed

Dr Sri Harika Bonam

By Dr Sri Harika Bonam Consultant Obstetrician & Gynaecologist & Lap Surgeon, Apollo Cradle & Children’s Hospital, Jubilee Hills.

Fibroids are non-cancerous growths that develop in or around the womb (uterus). They are made up of muscle and fibrous tissue and are also known as uterine myomas or leiomyomas. 60-70% of women develop fibroids in their lifetime or by the age of 50. Half of them do not have any symptoms. Uterine Fibroid is also the leading cause of hysterectomy in our country.

The size of the fibroid can vary from a few mms to up to 20-30 cm. They can be located in the lining of the womb, within the wall, in the outer layer of the womb or in the broad ligament. Depending on the size, location, and rapidity of the growth they can present with a wide variety of symptoms.

 

 

 

They include:

  • · heavy bleeding during periods
  • · tummy (abdominal) pain during periods or in between periods
  • · lower back pain
  • · Frequent urination
  • · Difficulty in passing stools.
  • · pain or discomfort during sex.
  • · Irregular intermenstrual bleeding

In rare cases, it can cause difficulty in conceiving.

Why do fibroids develop?

The exact cause is unknown, but they have been linked to the hormone oestrogen, the female reproductive hormone produced by the ovaries.

Oestrogen levels are at their highest in the reproductive age of 16 to 50 years, and so are the fibroids.

They tend to shrink when oestrogen levels are low, such as after menopause. It’s also thought they occur more often in overweight/ obese because being overweight increases the level of oestrogen in the body.

Fibroids are thought to develop more frequently in women of African-Caribbean origin. Studies also suggest that there is a possible genetic cause.

Who needs treatment?

Treatment may not be necessary if you do not have any symptoms, or if you only have minor symptoms that are not significantly affecting your everyday activities.

Fibroids often shrink after menopause and symptoms will disappear gradually.

What are the treatment options for fibroids?

Treatment depends on the age; type and severity of symptoms; location, number and size of fibroids; fertility concerns; response to any previous treatments & patient’s wishes.

1st line is medical; which could be no hormonal or hormonal, that reduces the bleeding/shrinks the fibroids. Failing which, further options would be non-surgical and surgical options.

Non-surgical options include MIRENA, Uterine artery embolization, MRI MRI-guided procedures.

MIRENA – a small ‘T’ shaped plastic device that releases progesterone hormone slowly inside the womb which gradually shrinks the fibroid size and gives symptomatic relief. MIRENA also has the benefit of acting as a contraceptive method. Side effects include irregular bleeding, spotting & up to 1/3rd may not respond and may end up requiring surgery.

Uterine artery embolization (UAE) is an alternative to surgery & may be recommended for women with large fibroids. It is a procedure done under local anaesthesia, in which blood vessels that supply the fibroids are blocked with gel/foam-like particles causing them to shrink. Side effects include excess vaginal discharge, and pain … can last up to a few days to weeks post-procedure and up to 1/5th may not have symptomatic relief, necessitating surgery on a later date.

MRI-guided procedures like focused ultrasound or percutaneous laser ablation are relatively new techniques for treating fibroids, and the long-term benefits and risks are unknown.

What are the surgical options?

Surgery may be considered if symptoms are severe and have not responded to medical management. The two main types of surgery done for fibroids are: –

1) myomectomy – a procedure to remove the fibroid and suture the womb,

2) hysterectomy – removal of womb.

Which one to be decided, depends on multiple factors like woman’s age; number, site and size of fibroids; family completed or not; any associated medical problems and women’s choices after counselling pros and cons of both procedures.

Either of the procedures can be done by the keyhole method(laparoscopy) of surgery which has many advantages over conventional open surgery, like less blood loss, less complications, early recovery, early discharge and better satisfaction.

“I got 99 problems but having a uterus ain’t one”.

Does Fibroids in pregnancy cause any complications?

Women with fibroids in pregnancy may experience tummy (abdominal) pain during pregnancy, and there’s a risk of preterm labour.

If large fibroids block the vagina, a caesarean section might be necessary. Women with fibroids also tend to have excess bleeding after delivery or during caesarean section.

Understanding Renal Hypertension and Kidney Health

Dr. Salil Jain

By Dr. Salil Jain, SENIOR DIRECTOR & HOD NEPHROLOGY & RENAL TRANSPLANT, Fortis Hospital, Gurgaon

On World Hypertension Day, it’s crucial to shed light on a lesser-known type of high blood pressure that originates from kidney disease – renal hypertension.

Renal hypertension occurs when there is elevated blood pressure due to kidney disease, specifically caused by narrowing in the arteries that supply blood to the kidneys. This narrowing, known as renal artery stenosis, can affect one or both kidneys, disrupting blood flow and triggering a cascade of physiological responses that lead to increased blood pressure.

The primary cause of renal artery stenosis is often atherosclerosis, a condition characterized by the hardening and narrowing of arteries due to plaque buildup. Less commonly, renal artery stenosis may result from fibromuscular dysplasia, a condition where the structure of the renal arteries develops abnormally. Individuals with risk factors such as smoking, high cholesterol, diabetes, and a family history of kidney disease are more prone to developing renal hypertension.

One of the challenging aspects of renal hypertension is that it often presents without noticeable symptoms. However, in cases of severely elevated blood pressure, individuals may experience symptoms such as headaches, confusion, vision changes, bloody urine, nosebleeds, or chest pain. Unfortunately, these symptoms may not always be attributed to high blood pressure, leading to delayed diagnosis and treatment.

Fortunately, there are several effective treatment options available for managing renal hypertension:

· Medications: Blood pressure-lowering medications are the cornerstone of treatment for renal hypertension. Multiple medications may be necessary to achieve adequate blood pressure control.

· Angioplasty and Stenting: In some cases, minimally invasive procedures such as angioplasty and stenting may be performed to widen the narrowed renal arteries and improve blood flow. Angioplasty involves inflating a balloon in the artery to widen it, while stenting involves placing a wire-mesh stent to keep the artery open.

· Surgery: Surgical intervention, such as bypass surgery, may be considered in rare cases where angioplasty and stenting are not feasible or effective.

Longer Sprint Intervals Can Improve Muscle Oxygen Utilization Compared to Shorter Intervals

Longer Sprint Intervals

Sprint interval training (SIT) is a form of exercise characterized by cycles of intense exercise which are interspersed by short durations of rest. In a recent study, researchers from Japan deep dive into the intricate connections among various parameters of SIT, such as duration and repetitions, and the resulting physiological responses. Their findings can aid in developing well-informed and tailored sprint training regimens that significantly benefit the modern-day population.

Physical activities like jogging, walking, cycling, and sprinting are activities known to engage the musculoskeletal system and result in the utilization of energy. Sprint interval training (SIT) is a type of sprinting exercise that involves cycles of intense exercise followed by a short duration of rest. How the durations of exercise and rest are structured can affect the impact of SIT on physiological responses. In recent years, the field of sports physiology has witnessed increased interest in optimizing SIT protocols. This surge can enhance the recognition of SIT’s efficacy in improving athletic performance and overall well-being, highlighting its versatility as a tool for promoting health and fitness.

Now, to highlight the benefits of SIT, a team of researchers from Japan, comprising Dr. Takaki Yamagishi from the Department of Sport Science and Research, Japan Institute of Sports Sciences and Human Performance Laboratory at the Comprehensive Research Organization at Waseda University, and Professor Yasuo Kawakami who directs the Human Performance Lab and is from the Faculty of Sport Sciences, Waseda University, conducted SIT experiments with healthy human volunteers in a recent study. This study was published online in Medicine & Science in Sports & Exercise journal on March 7, 2024.

Explaining the motivation behind their research work, Yamagishi says, “Establishing a minimum dose of exercise training to bring about training benefits, such as aerobic fitness, has been one of my main research interests. Due to the support from Prof. Kawakami and other co-authors, along with the collaboration with Waseda University, this unique research work using a multifaceted approach was possible.”

The team of researchers matched two different sprint interval exercises (SIE) for the total duration of sprint and sprint-to-rest ratio. They analyzed the influence of SIE on physiological and metabolic responses by examining pulmonary oxygen uptake (V̇O2) levels and changes in tissue oxygenation index (∆TOI) in thigh muscles. Additionally, they utilized the T2-weighted magnetic resonance imaging (MRI) technique to assess the activation of thigh muscles.

The researchers highlight that SIE20, comprising of two 20-second sprints with 160-second recovery, outperformed SIE10, which involved four 10-second sprints with 80-second recovery. While both the SIE protocols significantly increased whole-body and peripheral oxidative metabolism and the activation of the major thigh muscles, as indicated by the increases in V̇O2 levels, ∆TOI, and MRI T2 values, respectively, greater peripheral oxidative metabolism was achieved with SIE20. They also observed that successive sprint repetitions in SIE10 did not correlate with greater oxidative metabolism.

Elaborating on the real-life applications and impact of the present research, Yamagishi says, “In today’s fast-moving world, lack of time is a major hindrance to regular physical activity. However, the exercise modalities employed in our study require less than 15 minutes to complete and provide considerable health benefits.”

In summary, the findings from this study can address important research gaps in SIT, such as the effects of minimum sprint duration and repetitions on aerobic and metabolic responses in humans. In-depth studies on low-volume SIT have the potential to improve training programs and exercise regimens. Sharing his concluding thoughts, Yamagishi says, “Exercise guidelines proposed by major organizations such as the American College of Sports Medicine are updated every 5 to 10 years, and we are hopeful that our study can be a part of it. Future studies on SIE can build on our findings to establish the dose-response relationship between exercise volume or intensity and the degree of training adaptations.”
