Effect of Hand-free “Chin Tuck against Resistance (CTAR)” Exercise on Hyoid Bone Movement and the Degree of Aspiration in Stroke Patients with Dysphagia: A Report of 2 Cases / 대한연하장애학회지

This study recruited two men with dysphagia after stroke, aged 57 and 62 years. They had difficulty using both hands properly due to paralysis of the left upper extremity and rheumatoid arthritis of the right hand in patient 1 and paralysis of both upper extremities in patient 2. This study examined the effects of 4 weeks of hand-free chin-tuck-resistance exercise on the hyoid movement and aspiration. The exercises involved isotonic and isometric parts. In isometric CTAR, the patients were asked to chin tuck against the device 3 times for 60 s each with no repetition. In isotonic CTAR, the patient performed 30 consecutive repetitions by strongly pressing against the resistance device and then releasing it. Based on a video fluoroscopic swallowing study, the degree of aspiration was measured using the Penetration-Aspiration Scale (PAS) and two-dimensional motion analysis of the hyoid bone. Post-intervention, the hyoid movements in both patients improved by 0.16 and 0.22 cm (anterior movement), and 0.26 and 0.28 cm (superior movement), and the PAS scores decreased by 2 and 2 points, respectively. This study confirms that hands-free chin-tuck resistance exercise is applicable and helpful for improving the hyoid movement and reducing aspiration in patients with dysphagia after stroke. Therefore, this exercise can be introduced as an intervention for improving the swallowing function in patients with dysphagia who have difficulty using both hands.

Systemic Lupus Erythematosus Presenting with Idiopathic Retroperitoneal Fibrosis / 대한내과학회지

Retroperitoneal fibrosis (RPF) is a rare inflammatory fibrotic condition affecting the peri-aortic retroperitoneum in which fibrosis of the surrounding tissue can encase the ureters, resulting in obstructive uropathy. RPF is generally idiopathic in nature, but may also arise in response to other conditions, such as malignancies, infections, surgery, radiotherapy, or drugs. Idiopathic RPF is commonly seen in association with various autoimmune diseases, such as autoimmune thyroiditis, autoimmune pancreatitis, rheumatoid arthritis, and systemic lupus erythematosus (SLE). Here, we describe the first case of RPF in Korea. A 44-year-old man with SLE presenting with pain in both flanks due to RPF is discussed, along with a review of the relevant literature.

Intramural Hematoma with Air Density on Computed Tomography after Percutaneous Kyphoplasty

Iatrogenic aortic dissection occurs in association with diverse invasive procedures. It occurs primarily as a complication of cardiac surgery or after catheterization procedure. We found a case of iatrogenic abdominal aortic dissection caused by traumatic needle injury. The patient complained of abdominal pain after balloon kyphoplasty. Abdominal computed tomography (CT) showed intramural hematoma with air density suggestive of an iatrogenic cause. The patient was managed conservatively, and no lesion progression was noted in the follow-up CT. To the best of our knowledge, this is the first case of iatrogenic aortic dissection associated with kyphoplasty.

Myocardial Ischemia by Aggravation of Myocardial Bridging

Myocardial bridging (MB) occurs when the myocardium covers a segment of a major epicardial coronary artery, resulting in a tunneled arterial segment. Although MB is generally considered benign, it has been associated with myocardial ischemia. A 70-year-old man with MB (50% luminal narrowing during systole) at the mid-left anterior descending artery (LAD) on previous coronary angiography (CAG) visited our hospital with worsening chest pain. His blood pressure (BP) was not well controlled because of poor compliance. Follow-up CAG showed that MB at the mid-LAD progressed to severe stenosis (>90% luminal narrowing during systole) and the total length of tunneled artery extended from 22.5 to 23.9 mm. His chest pain was relieved by BP control. This is the first report of myocardial ischemia secondary to progression of MB demonstrated by CAG in Korea.

Resolution of Type 2 Diabetes Mellitus Following Interferon-alpha Therapy for Chronic Hepatitis C / 임상당뇨병

Hepatitis C virus (HCV) mainly affects the liver, but several tissues outside the liver have also been reported to be involved. It has been hypothesized that diabetes could be one of these extrahepatic conditions attributable to HCV infection. The specific mechanisms by which HCV leads to type 2 diabetes are not fully understood, but it seems that an increase in insulin resistance associated with both steatosis and overproduction of proinflammatory cytokines could play a crucial role. We report a patient whose type 2 diabetes that was resolved following interferon-alpha (IFN-alpha) therapy for HCV. A 57-year-old man presented with fatigue, polyuria, and polydipsia. He was newly diagnosed as type 2 diabetes and chronic hepatitis C. He was started on subcutaneous insulin and IFN-alpha. After 24 weeks of treatment with IFN-alpha, the results of HCV polymerase chain reaction were negative, and his diabetes had resolved. Our case shows a resolution of diabetes after IFN-alpha therapy for chronic hepatitis C. Although it is unclear whether the resolution of diabetes in this case occurred as an effect of IFN-alpha or as a result of becoming HCV RNA-negative, our finding suggest roles of IFN-alpha and HCV infection in the pathogenesis of diabetes.

A Case of Acute Cholecystitis Caused by Plasmodium vivax Infection / 대한췌담도학회지

Acute cholecystitis as a complication of malarial disease is a rare condition, especially with Plasmodium vivax infection. A 62 year-old-female was admitted via emergency room (ER) due to high fever (40.3degrees C) and epigastric pain. Initial abdominal ultrasound and computed tomography (CT) scan showed edematous gallbladder with stone, which suggested acute calculous cholecystitis. Emergency percutaneous transhepatic gallbladder drainage (PTGBD) was done with systemic antibiotic therapy. The clinical course, however, unusually worsened with hypotension and intensive care unit (ICU) management was done. Four days after admission multi-focal splenic infarction was developed and Plasmodium vivax infection was diagnosed afterward. The clinical symptoms and laboratory results, including fever and epigastric pain, improved dramatically after anti-malarial treatment and cholecystectomy was done. The resected gallbladder (GB) specimen shows vasculitis pattern with capillary red blood cell (RBC) engorgement, which suggests the cause of cholecystitis was due to Plasmodium vivax rather than GB stone.

A Case of Pseudovaginal Perineoscrotal Hypospadias with 5alpha-reductase Deficiency / 대한비뇨기과학회지

Male pseudohermaphroditism can be caused by absent m llerian regression, inadequate synthesis of testosterone, inadequate synthesis of dihydrotestosterone, or androgen receptor deficiency. Defects in either the production or the action of androgenic steroids have been demonstrated to cause pseudovaginal perineoscrotal hypospadias, a syndrome of male pseudohermaphroditism. This is mostly caused by a deficiency of 5alpha-reductase, which controls the conversion of testosterone to 5alpha-dihydrotestosterone. We report a case of male pseudohermaphroditism due to 5alpha-reductase deficiency who was born with ambiguous genitalia and was reared as female.

Retroperitoneal Laparoscopic Renal Cyst Marsupialization / 대한비뇨기과학회지

PURPOSE: Retroperitoneoscopy has begun to gain its acceptance for urologic surgery, the aim of this study was to assess the clinical efficacy and safety of retroperitoneal laparoscopic surgery for simple renal cysts. MATERIALS AND METHODS: Three female and five male patients ranging from 37 to 72 years in age underwent retroperitoneal laparoscopic marsupialization of symptomatic renal cysts from March 1996 to February 1998. The retroperitoneal space was created by saline-filled balloon made of middle finger of a No 8 surgical glove and 16Fr Foley catheter. Two patients had prior percutaneous cyst aspiration and sclerotherapy and two patient had a parapelvic renal cyst. We assessed the mean operative time, postoperative hospital stay and complications. RESULTS: Mean operative time was 98 minutes(range; 80-140), the average postoperative hospital stay was 2.5 days(range; 2-3). All eight patients were successfully managed and have remained pain free with no evidence of recurrence of the cyst at the 3-12months follow-up. Complications included 2 cases of subcutaneous emphysema and 1 case of peritoneal tear. CONCLUSIONS: Retroperitoneal laparoscopic unroofing is a safe, effective, and minimally invasive treatment for symptomatic or recurrent renal cyst.

A Case of Vesical Endometriosis / 대한비뇨기과학회지

Endometriosis is defined as the presence of endometrial tissue (gland and stroma) outside the uterus. The most frequent sites of implantation are the pelvic viscera and the peritoneum. About 1% of woman with endometriosis have urinary tract lesions, of which 85% involve the bladder. We report one case of vesical endometriosis that have been treated by partial cystectomy.
