In the quiet streets of Thiruvananthapuram, on a February morning in 2026, the medical world of Kerala lost one of its brightest stars. Prof. Kasim Abdul Salim, or “Salim Sir” to thousands who revered him, passed away at 86. Founder of the Department of Clinical Hematology at Government Medical College, Kozhikode, former Principal of the institution, internationally trained hematologist, and a clinician whose skills bordered on the legendary, he left behind not just a department or a curriculum, but an entire philosophy of medicine—one that placed the patient’s story, the clinician’s eyes and ears, and human compassion above the gleaming machinery of modern diagnostics.240

Students called him the “lion king” not for any stern authority of position, but for the sheer authority of wisdom. In an era when CT scans, MRIs, and genetic tests promised to replace the art of diagnosis, Salim Sir demonstrated, time and again, that a meticulously taken history and a sharply focused physical examination could still outperform specialists armed with the latest technology. He was a phenomenon—more neurologist than many neurologists, more cardiologist than cardiologists, and a hematologist who treated blood disorders with the precision of a scientist and the heart of a family elder.22

Born around 1940, Kasim Abdul Salim graduated with his MBBS from Government Medical College, Thiruvananthapuram, in 1963 and completed his MD in General Medicine in 1966. He went on to earn prestigious qualifications from the Royal College of Physicians (London) in 1978 and the Royal College of Pathologists in 1982, along with fellowships that took him to international shores. Yet his heart remained in Kerala. He built the hematology department at Kozhikode Medical College from the ground up, making advanced care for thalassemia, hemophilia, and blood cancers accessible to ordinary people in North Kerala. He later served as Principal, introducing administrative reforms while fiercely guarding academic rigor. He also taught in Saudi Arabia at King Khalid University and briefly worked with the NHS in London, but his most profound influence was on generations of Indian doctors.41

The Cornerstone: History-Taking as Sacred Ritual

Salim Sir’s diagnostic method was deceptively simple: listen first, observe sharply, investigate sparingly. In his home clinic on Jail Road in Kozhikode, long queues formed daily—rich businessmen alongside daily-wage laborers. No one was rushed. He would sit with each patient, often for 20-30 minutes, delving not just into symptoms but into family stories, financial struggles, marital tensions, and dietary habits.

One former student recalled arriving at his home clinic and seeing a tired farmer waiting patiently. Salim Sir emerged, greeted the man warmly, and said, “Come, my friend, tell me everything from the beginning. Not just the pain—how is your wife managing the fields while you are unwell? How are the children studying?” The farmer, visibly moved, poured out his heart. Within minutes, the clinical picture crystallized. “Investigations are servants, not masters,” Salim Sir often told his residents. “If you let them lead, you have already missed the diagnosis.”

He criticized the creeping over-medicalization of healthcare. Years before global alerts, he warned against the casual overuse of proton pump inhibitors (PPIs). During a conversation with his nephew, Dr. Harish Kareem, then pursuing DM in Gastroenterology, Salim Sir remarked, “Harish, these PPIs are being handed out like sweets. Mark my words—they are not as harmless as everyone thinks. The gut is a delicate ecosystem; we should not disturb it lightly.” In 2003, this was contrarian; by 2010, FDA warnings validated his foresight.40

Vivid Anecdotes from the Wards

His reputation rested on real cases that sounded almost mythical to students. One morning in the medical ward, a house surgeon—Dr. Murali K.M.—watched a patient with a bulging eye being referred from Ophthalmology for bone marrow examination to rule out AML or chloroma. The CT scan had suggested something sinister. Salim Sir listened patiently to the history, then borrowed Murali’s stethoscope. He placed it gently over the patient’s eye and listened intently for a few seconds.

“Acute carotico-cavernous fistula,” he announced calmly. The room fell silent. “No need for bone marrow today. Arrange for carotid angiography.”

Murali’s eyes widened. “Sir… just like that?”

Salim Sir smiled faintly. “The bruit is classic if you know where to listen. Why put the patient through more when the answer is right here?” Angiography later confirmed the diagnosis. The ophthalmologist, upon hearing, was reportedly stunned.40

Another day, while chatting casually with a long-term patient about her family, Salim Sir learned of her husband’s unexplained abdominal pain that had baffled multiple gastroenterologists. He asked gentle, probing questions for about 15 minutes—pain triggers, color of urine, family history, stress factors. Then, quietly, he said, “I think your husband has a condition called acute intermittent porphyria. Get his urine tested during an attack for porphyrins and precursors.”

The woman looked doubtful but followed through. The tests confirmed it. When the husband later visited, Salim Sir greeted him warmly: “So, you are the mystery man giving everyone headaches! Let’s get you sorted properly.” The patient’s relief was palpable; finally, someone had truly listened.1

Then there was the young woman with dramatic tremors, labeled “functional” by neurology after a CT scan. Transferred to Salim Sir’s ward, she sat nervously. He took a detailed history, exploring onset, associated symptoms, family background, and dietary habits. Instead of a full neurological exam, he simply used his ophthalmoscope as a makeshift torch to peer into her eyes.

“Kayser-Fleischer ring,” he declared softly. “This is Wilson’s disease.” The only physical maneuver he performed. Despite an initial dismissive note from ophthalmology (who had used a basic torch, not a slit lamp), metabolic tests confirmed the diagnosis. Murali wheeled the patient back to Ophthalmology with the news. The lesson: sometimes the most sophisticated tool is an old ophthalmoscope and a keen mind.40

Parkinsonism cases were his masterclass in observation. A patient who had already seen a neurologist and undergone scans sat before him. Salim Sir observed from a distance for a few moments—the mask-like face, reduced blink rate, subtle resting tremor, stooped posture. He barely touched the patient.

“Parkinsonism,” he stated. Turning to the residents, he said firmly, “It must be diagnosed from a distance. If you start examining the patient, you have half-missed the diagnosis. Once you start investigating, you have completely missed it.” The clinical findings were unequivocal. His point was clear: excessive hands-on probing or premature tests could cloud the obvious pattern.40

The Mentor Who Planted Seeds

As a teacher at Kozhikode Medical College (and other government colleges), Salim Sir was unforgettable. He carried instruments and a camera to document teaching moments. Ward rounds were theatrical yet deeply educational. He would call students forward: “Come, feel this spleen. Notice the texture? Now, correlate with the history.” Or he would recount NEJM case records from memory, complete with dates and details, astonishing everyone with his recall.

His nephew Dr. Harish Kareem remembered vacations spent at his home. Salim Sir would emerge from hours of reading journals—NEJM and BMJ—with childlike excitement. “Harish, you must read this article on gut microbiota! We are only beginning to understand how complex it is.” In 2011, he urged Harish to try fecal microbiota transplant for a young woman with refractory Crohn’s disease. “It might work when steroids fail,” he said enthusiastically. The procedure succeeded remarkably; she weaned off medications and stayed in remission. It may have been among the earliest such attempts in India.40

He treated rich and poor alike with equal respect. In the clinic, a wealthy patient might wait alongside a laborer, and both would leave feeling heard. “Medicine is not just science,” he would say. “It is humanism. Understand the person, and the disease often reveals itself.”

Even after his wife Pathummal (affectionately Mami) passed away in 2021, he continued seeing patients and mentoring, though those close to him noted he was never quite the same. He inspired more than twenty family members to enter medicine, including his four sons. His home was a hub of learning and warmth.

A Lifelong Learner and Visionary Critic

Salim Sir remained a student until the end. He read journals daily, staying abreast of advances while remaining critical of unproven trends. He carried a camera to document interesting cases for teaching. In hematology, his judgment guided when to order labs and when clinical management sufficed—crucial for resource-limited settings managing thalassemia and hemophilia.

He foresaw issues with excessive interventions long before they became mainstream concerns. His criticism of over-reliance on investigations was not Luddite but wise: “Technology is a tool. Let it confirm, not replace, your judgment.”

Enduring Legacy

Today, his former students—scattered across India, Canada, Australia, and beyond—carry his teachings. Dr. Murali K.M. captured it best: “In the forest of medical stalwarts… Salim Sir was the lion king… His clinical brilliance was beyond dispute… The lion will not roar again. But his echo will never fade.”35

In an age of AI diagnostics and high-tech hospitals, Prof. Kasim Abdul Salim reminds us that the most powerful instrument remains the compassionate, observant clinician who truly listens. His life blended rigorous science with profound humanism. He treated not just diseases but people—understanding their fears, their families, their struggles.

As one tribute noted, his practice was compassion, his curiosity eternal. For doctors navigating the complexities of modern medicine, his message endures: Slow down, listen deeply, observe sharply, and never forget the human behind the symptoms.

The queues at his clinic are gone now, but the lessons live on in every bedside where a young doctor pauses, takes a thorough history, and remembers the lion king who showed that clinical medicine, at its best, is both art and science—and above all, an act of profound humanity.
