Patient Wang Moumou, male, 59 years old, came to our department on June 25, 2009. The patient reported pain in his right shoulder for more than a month, and the pain was especially severe at night. He had been treated in two military hospitals without any significant effect. He said that his son had been treated by the chief of surgery at our hospital for kidney stones several years ago, but he was not cured. After reading the outpatient medical records of the first two hospitals, I was diagnosed with frozen shoulder and was treated with massage, physiotherapy and small acupuncture, but the result was very little. While I was looking through the medical records, Dr. Jin-Sheng Wu, who was sitting across from me, did a routine physical examination of the patient and indeed found three pressure points in the right subclavian, pre-shoulder and right scapular post, respectively. After the initial communication with Dr. Wu, we all had doubts about the diagnosis of “frozen shoulder” in the first two hospitals. Since all physical examinations were negative, it was not easy to come up with a definite diagnosis for a while, so we had to continue to ask detailed questions about the medical history. During the subsequent conversation, we were reminded by a comment from the patient’s family. The patient’s family said, “He has always been in good health, but recently he suddenly lost nearly 20 pounds, is it related to high blood sugar?” He then took out a lab slip from his bag and handed it to me (the blood sugar column on it said 8.57 mmol/l, and the rest of the biochemical items were normal). It is true that high blood glucose can cause weight loss, but the weight loss in such a short period of time does warrant attention. Although the patient did not feel any discomfort (no fever, no cough, chest tightness, etc.), Dr. Wu still insisted that the patient be further examined. Looking at Dr. Wu’s focused and serious eyes, I suddenly remembered a patient I met three years ago during my internship at a provincial Chinese medicine doctor. It was an old lady, a retired cadre from a nearby provincial unit, with a very kind face and a particularly cheerful attitude. She also came to the clinic with periarthritis pain. After examination, the doctor treated her for frozen shoulder. After about half a month of treatment, he still did not see any improvement. However, the old man kept going and never stopped. After about 20 days of treatment, he suddenly stopped coming. At that time, I talked to the teacher who received the treatment, and he said that maybe there was something going on at home. This case was also gradually forgotten. Less than a month later, another patient in the same unit as her told us the sad news that the old lady died 7 days after she was diagnosed with pancreatic cancer. This incident is still fresh in my mind. Thinking of this, I immediately prescribed an abdominal ultrasound and chest X-ray for the patient and asked the patient to undergo a thorough examination. Since I didn’t know what the result was when I took the temperature disease examination on Saturday, I went to the comprehensive examination department and radiology department to inquire as soon as I got to work on Monday. As a result, it was confirmed by Director Zhan and Director Zhai that the ultrasound showed a 3.6*2.6cm size tumor in the adrenal gland and liver and lung metastasis had already appeared. The feeling at that time was really very complicated. While it gave us a correct diagnosis and won precious time for further treatment of the patient, there were some fears because a slight negligence would misdiagnose the tumor as frozen shoulder and mistreat it with unimaginable consequences, which not only affected the reputation of our hospital, but also was a great irresponsibility to life. The purpose of writing this case for the benefit of our colleagues is twofold: firstly, to spur ourselves to continue to study our professional knowledge in clinical work, and to strengthen the learning of diagnosis and differential diagnosis, to cultivate a more rigorous working style, to diagnose carefully, to look at the patient carefully, so as to avoid misdiagnosis; secondly, we hope that our young doctors must believe in their own ability, and must not be presumptuous. The great leader Chairman Mao taught us: there is no difficulty in the world, only fear of those who have the will. Although we are in a second-class hospital, not as well-known as Qilu provincial, but as long as we study hard, study hard, patient consultation, careful diagnosis, as famous doctors can emerge, out of their own way. There is a saying that the road is as long as the iron, and now step forward from the head. As a new force, we have the confidence and ability to make the sign of the electric power hospital bigger and stronger!
