The Role of Neurologists in Pain Management – Based on the Survey Conducted by the Korean Neurological Association in 2020

Background@#Pain is one of the most common chief complaints in neurological field. Authors try to inform the current situation of pain medicine in neurological practice and present an effective method for pain-related education during neurology residency and for practicing neurologists. @*Methods@#A survey was conducted from November 16 to November 27, 2020 for members of the Korean Neurological Association, and the results were analyzed. @*Results@#About two-thirds of neurologists replied that more than 25% of their patients were suffered from diverse pain including headache, spine pain or neuropathic pain. Despite many patients are visiting to neurologist for pain treatment, most neurologists are aware that they have not received sufficient practical pain education in the past and present. Therefore, they want more educational opportunities in pain medicine including interventional pain management and physical and pharmacologic therapies for more effective treatment. @*Conclusions@#More follow-up studies on pain treatment and education should be conducted. It is also essential that the members of the society continue to interest and participate in the change of the pain education program.

Single Nodular Pulmonary Amyloidosis: Case Report / 결핵및호흡기질환

Amyloidosis is defined as the presence of extra-cellular deposits of an insoluble fibrillar protein, amyloid. The pulmonary involvement of amyloidosis is usually classified as tracheobronchial, parenchymal nodular, or diffuse alveolar septal. A single nodular lesion can mimic various conditions, including malignancy, pulmonary tuberculosis, and fungal infection. To date, only one case of nodular pulmonary amyloidosis has been reported in Korea, a case involving multiple nodular lesions. Here, we report and discuss the case of a patient having single nodular amyloidosis.

A Case of Lung Carcinoma with Rhabdoid Phenotype Mimicking an Aspergilloma in Patient with Recurrent Hemoptysis / 결핵및호흡기질환

Malignant rhabdoid tumor was first discovered in the kidney, and rhabdoid tumor of the lung was first reported in 1995. These were included as the variants of large-cell carcinoma, according to the 1999 World Health Organization classification of lung tumors. The rhabdoid tumor of the lung exhibits aggressive biological behavior and has a poor prognosis, and only a few reports of this tumor exist. We report a case of lung carcinoma with a rhabdoid phenotype, initially misdiagnosed as an aspergilloma, in a 48-year-old man who presented with recurrent hemoptysis. The chest computed tomography scans showed a huge consolidative lesion with an air crescent sign in the left upper lung and no contrast-enhancing lesion. An aspergilloma was diagnosed by the radiologist. However, after surgical excision and pathological examination, rhabdoid carcinoma was diagnosed. A surgical resection helps to make it possible to pathologically distinguish a malignancy from an aspergilloma.

A Case of Endobronchial Aspergilloma Associated with Foreign Body in Immunocompetent Patient without Underlying Lung Disease / 결핵및호흡기질환

Aspergillus causes a variety of clinical syndromes in the lung including tracheobronchial aspergillosis, invasive aspergillosis, chronic necrotizing pulmonary aspergillosis, allergic bronchopulmonary aspergillosis, and aspergilloma. Aspergilloma usually results from ingrowths of colonized Aspergillus in damaged bronchial tree, pulmonary cyst or cavities of patients with underlying lung diseases. There are a few reports on endobronchial aspergilloma without underlying pulmonary lesion. We have experienced a case of endobronchial aspergilloma associated with foreign body developed in an immunocompetent patient without underlying lung diseases. A 59-year-old man is being hospitalized with recurring hemoptysis for 5 months. X-ray and computed tomography scans of chest showed a nodular opacity in superior segment of left lower lobe. Fiberoptic bronchoscopy revealed an irregular, mass-like, brownish material which totally obstructed the sub-segmental bronchus and a foreign body in superior segmental bronchus of the lower left lobe. Histopathologic examinations of biopsy specimen revealed fungal hyphae, characteristic of Aspergillus species.

A Case of Pheochromocytoma Accompanied with Alveolar Hemorrhage and Cardiogenic Pulmonary Edema / 결핵및호흡기질환

Pheochromocytoma is derived from the chromaffin tissue. The typical finding of pheochromocytoma is paroxysmal hypertension accompanied with various signs and symptoms that are due to the excess of catecholamines or other bioactive substances. Yet the diagnosis is sometimes difficult to make because its clinical presentation is quite variable. Especially, hemoptysis is a very rare symptom, so the diagnosis is often missed or delayed. Without making the correct diagnosis and then subsequently administering treatment, the condition may be fatal. We herein report on a 68 year-old woman who was admitted because of abdominal pain and hemoptysis. The initial radiologic findings suggested pulmonary edema with alveolar hemorrhage. The urine catecholamine levels were elevated and she developed catecholamine-induced cardiomyopathy. We performed bronchial arterial embolization and we administered alpha blocker medication for controlling the hemoptysis and hypertension. After the temporary symptomatic improvement, her clinical course was aggravated by pneumonia and pulmonary edema. In spite of performing definitive surgery for pheochromocytoma, she died of postoperative hemodynamic instability.

Two Cases of Iatrogenic Pneumothorax after Intra-Muscular Stimulation (IMS) Therapy / 결핵및호흡기질환

Recently, intra-Muscular Stimulation (IMS) therapy is being increasingly used for musculoskeletal pain. This procedure is generally regarded as a safe procedure for the general public. Some cases of iatrogenic pneumothorax caused by acupuncture have been reported in the medical literature. However, a case of an IMS therapy associated pneumothorax has not reported. We experienced two cases of iatrogenic pneumothorax after IMS therapy. A 62 year-old man received IMS therapy on the right shoulder due to posterior neck pain. After IMS therapy, acute dyspnea and chest discomfort developed. The other patient was a 74 year-old woman who also received IMS therapy. This patient experienced a nonproductive cough and acute dyspnea after the treatment. As the popularity of this form of alternative medicine increases, we might expect to see more cases of iatrogenic pneumothorax. Physicians should be aware of the adverse events associated with IMS therapy.

A Case of Wegener's Granulomatosis that Presented as a Single Lung Mass / 결핵및호흡기질환

Wegener's granulomatosis is a disease with an unknown etiology that is characterized by necrotizing granulomatous vasculitis involving the upper and lower respiratory tract and the kidneys. The typical pulmonary findings are bilaterally involved multiple variable sized nodules. We report a case of Wegener's granulomatosis that presented as a single lung mass. A male patient presented with a nasal obstruction, arthralgia, cough, and intermittent dyspnea. The chest radiograph showed a mass, approximately 4.5 cm in diameter, in the right lower lobe. Lung cancer or tuberculosis was initially considered. However, the clinical, laboratory and pathological findings of the mass indicated Wegener's granulomatosis. The patient was administered prednisolone and cyclophosphamide, and improved temporarily. Unfortunately, the immunocompromised patient expired as a result of respiratory failure with pneumonia.

Clinical Characteristics of Lung Cancer Diagnosed in Chonnam National University Hospital(CNUH) Since 2000 / 결핵및호흡기질환

BACKGROUND: Lung cancer has been the leading cause of cancer death in South Korea since 2000. This study examined the clinical characteristics of lung cancer patients diagnosed in a community hospital from the year 2000 to 2005, and compared these results with previously reported statistical data. METHOD: The lung cancer data in a form of an electronic medical record was downloaded from the hospital medical information system. The clinical characteristics of the 1,509 patients with lung cancer were analyzed retrospectively. RESULT: The mean age of the patients was 63.7 years. 82.5% and 74.5% of the patients were men and smokers, respectively. Squamous cell carcinoma (41.6%) was the most common pathology type followed by adenocarcinoma(32.3%) and small cell carcinoma(13.9%). When 604 patients who were diagnosed from 2000 to 2003 were compared with 905 patients diagnosed from 2004 to 2005, the age of patients increased significantly (61.5 years vs. 65.1 years; p<0.001) and the proportion of adenocarcinomas was significantly higher(29.3% vs. 34.4%; p=0.046). CONCLUSION: Among the major histology types of lung cancer, the incidence of adenocarcinoma has been increasing recently. The age of the lung cancer patients at diagnosis is getting older. This is despite the fact that the distributions of the initial anatomic stages have not changed significantly.

Primary Endobronchial Leiomyoma Combined with Uterine Leiomyoma / 결핵및호흡기질환

Leiomyoma of the bronchus is a very rare benign tumor of the lung. Most endobronchial leiomyomas occur as secondary foci of primary uterine leiomyoma. We herein report a case with endobronchial tumor that had a different pathology from a primary resected uterine leiomyoma and was therefor considered a primary endobronchial leiomyoma. A 51-year-old woman with a history of uterine myoma presented with productive cough and fever. Bronchoscopy revealed a lightly yellow colored mass lesion that totally obstructed the orifice of the left lower lobe of the lung. The diagnosis of leiomyoma was made by histological examination of the obtained specimen. We considered the possibility of a benign metastasizing pulmonary leiomyoma. For treatment and differential diagnosis, a left lower lobe lobectomy of the lung and total hysterectomy with bilateral salphingooopherectomy were performed. The differences between lung and uterine lesions were confirmed by morphologic finding and immunohistochemical staining. The pathological diagnosis was primary endobronchial leiomyoma combined with uterine myoma.

A Case of Pulmonary Thromboembolism Developed during Chemotherapy with Gemcitabine and Cisplatin for NonsmallCell Lung Cancer : A case report

Lung cancer patients have increased risk of thromboembolism (TE) due to various factors such as by hypercoagulability, tumor thrombosis, decrease of ambulation, and chemotherapy etc. Among these factors, chemotherapy associated TEs have been reported, although the causes and pathomechanisms of TEs were not clear. Recently, reports proposed the potential role of platelets in endothelial damage by the chemotherapeutic agents. We have experienced a case of pulmonary TE after systemic chemotherapy with gemcitabine and cisplatin. The patient complained aggravated exertional dyspnea after chemotherapy and diagnosed as pulmonary TE by computerized tomogram. After anticoagulation and interruption of the chemotherapy, improvement of exertional dyspnea and resolution of the pulmonary TE were observed

A Case of Adrenomyeloneuropathy

We report a 37-year-old man with adrenomyeloneuropathy who presented as progressive gait disturbance. He had spastic paraparesis, hyperreflexia with Babinski's signs, a sensory level at T-4, and loss of the vibration sense in the legs. No adrenal insufficiency was noted. There were frontal white matter abnormalities but no cervical spinal lesions on MRI. A nerve conduction study showed distal axonal neuropathy predominantly in the lower extremities. The plas-ma level of the saturated very long chain fatty acids was elevated. (J Korean Neurol Assoc 19(4):431~434, 2001)

Vigabatrin-Induced Multifocal Action Myoclonus in a Patient with Partial Epilepsy / 대한간질학회지

Vigabatrin-induced myoclonus is rarely described in adult with partial epilepsy, We report vigavatrin-induced mulrifocal action myoclonus in a 34 year-old female with symptomatic partial epilepsy. Hwe seizures were resistant to catbamazepine. Vigabatrin was started as add-on therapy and multifocal action myoclonus was developed one month later. Myoclonus disappeared after withdrawal of vigabatrin and reappeared with re-use of it. Based on clinical features of myoclonus, her myoclonus may be non-epileptic in nature.
