The term muscle herniation represents focal muscular protrusions through an acquired or congenital fascial defect. The anterior tibialis muscle is the most common site of herniation. Dynamic ultrasonography has become an important tool in dermatology for diagnosing suspected muscle herniation because it is a non-invasive, highly accurate, readily available and cost-effective imaging technique. We present here the case of a 21-year-old male Korean soldier who underwent dynamic ultrasonography to confirm the diagnosis of anterior tibialis muscle herniation.

Rituximab is a monoclonal antibody that targets B-lymphocytes, and it is widely used to treat non-Hodgkin's lymphoma. However, its use has been implicated in HBV reactivation that's related with the immunosuppressive effects of rituximab. Although the majority of reactivations occur in hepatitis B carriers, a few cases of reactivation have been reported in HBsAg negative patients. However, reactivation in an HBsAg negative/ HBsAb positive patient after rituximab treatment has never been reported in Korea. We present here an HBsAg-negative/HBsAb-positive 66-year-old female who displayed reactivation following rituximab plus CHOP chemotherapy for diffuse large B-cell lymphoma. While she was negative for HBsAg at diagnosis, her viral status was changed at the time of relapse as follows: HBsAg positive, HBsAb negative, HBeAg positive, HBeAb negative and an HBV DNA level of 1165 pg/ml. Our observation suggests that we should monitor for HBV reactivation during rituximab treatment when prior HBV infection or occult infection is suspected, and even in the HBsAg negative/HBsAb positive cases.

Background: s/Aims: This study aimed to compare the minimally invasive pancreatoduodenectomy with venous vascular resection (MI-PDVR) and open pancreatoduodenectomy with venous vascular resection (O-PDVR) for periampullary cancer. Methods: Data of 124 patients who underwent PDVR (45 MI-PDVR, 79 O-PDVR) between January 1, 2016, and December 31, 2023, was retrospectively reviewed. Results: MI-PDVR is significantly better than O-PDVR in terms of perioperative outcomes (median operation time [452.69 minutes vs. 543.91 minutes; p = 0.004], estimated blood loss [410.44 mL vs. 747.59 mL; p < 0.01], intraoperative transfusion rate [2 cases vs. 18 cases; p = 0.01], and hospital stay [18.16 days vs. 23.91 days; p = 0.008]). The complications until the discharge day showed no significant difference between the two groups (Clavien–Dindo < 3, 84.4% vs. 82.3%; Clavien–Dindo ≥ 3, 15.6% vs. 17.7%; p = 0.809). In terms of long-term oncological outcomes, there was no statistical difference in overall survival (OS, 51.55 months [95% CI: 35.95–67.14] vs.median 49.92 months [95% CI: 40.97–58.87]; p = 0.340) and disease-free survival (DFS, median 35.06 months [95% CI: 21.47–48.65] vs.median 38.77 months [95% CI: 29.80–47.75]; p = 0.585), between the two groups. Long-term oncological outcomes for subgroup analysis focusing on pancreatic ductal adenocarcinoma also showed no statistical differences in OS (40.86 months [95% CI: 34.45–47.27] vs.48.48 months [95% CI: 38.16–58.59]; p = 0.270) and DFS (24.42 months [95% CI: 17.03–31.85] vs. 34.35 months, [95% CI: 25.44–43.27]; p = 0.740). Conclusions MI-PDVR can provide better perioperative outcomes than O-PDVR, and has similar oncological impact.

Pseudomembranous necrotizing bronchial aspergillosis (PNBA) is a rare form of invasive aspergillosis with a very poor prognosis. The symptoms are non-specific, and the necrotizing plugs cause airway obstruction. Atelectasis and respiratory failure can be the initial manifestations. Recently, we treated an immunocompromised patient with PNBA, who presented with a sudden onset of atelectasis and acute respiratory failure. There were no preceding signs except for a mild cough and one febrile episode. Bronchoscopy revealed PNBA, and Aspergillus nidulans was cultured from the bronchial wash.

Urinothorax is rare cause of pleural effusion. Urinothorax should be considered when pleural effusion occurs in patients with urinary tract obstruction accompanied by retroperitoneal urinoma. It has been reported in patients with trauma, malignancy, kidney biopsy and renal transplantation. Most cases are diagnosed retrospectively by promt resolution of symptoms after relief of urinary obstruction. But diagnosis can be made based on clinical suspicion, radiological findings and biochemical analysis of the effusion and most important finding is the pleural level of creatinine is higher than the serum level. We experienced right pleural effusion in autosomal dominant polycystic kidney disease hemodialyzed. The patient had right urinoma in the retroperitoneal space before pleural effusion developed. After 3month, he complained acute dyspnea. There was no effect in resolving effusion by lowering dry weight. We thought alternative diagnostic possibility, urinothorax and checked the pleural fluid to serum creatinine ratio. Finally concluded that pleural effusion was urinothorax secondary to remnant left polycystic kidney rupture and tried left nephrectomy. The patient showed reduction of pleural effusion. It is important to alert physician to this condition and to avoid the other invasive diagnostic study.

BACKGROUND: Paronychia is a common infectious disease affecting fingernails and toenails. Although bacterial and fungal infections as well as mechanical trauma may play roles in the pathogenesis of this disease, there are few bacteriological studies about paronychia in military personnel. OBJECTIVE: To identify the causative bacteria of paronychia in military personnel. METHODS: We retrospectively analyzed the microbiological results of 145 patients who visited a tertiary referral hospital for Korean soldiers from August 2004 to October 2006. RESULTS: Twenty-eight different types of aerobic bacteria were identified, with the most common being Staphylococcus aureus (38.0%), Streptococcus pyogenes (7.2%), and Pseudomonas aeruginosa (5.4%). Staphylococcus aureus was identified mostly in finger and toe paronychial lesions and Pseudomonas aeruginosa was recovered commonly from toe paronychial lesions. All cases of paronychia were controlled by the combination of antiseptic dressing, topical antibacterial ointment, oral antibiotics, and antimycotic agents. CONCLUSION: The types of bacteria that most commonly caused paronychia in military personnel were Staphylococcus aureus, Staphylococcus pyogenes, and Pseudomonas aeruginosa. Thus, the commonly used oral antibiotics for paronychia, such as amoxicillin-clavulanate, clindamycin, and trimethoprim-sulfamethoxazole, are good choices in the treatment of paronychia in military personnel.

Subclavian and internal jugular vein catheters are widely employed for temporary hemodialysis access. Placement of subclavian venous catheter has many complications such as pneumothorax and hemothorax, etc. Incidence of subclavian vein obstruction due to thrombosis is probably greater than is commonly appreciated. Subclavian vein obstruction may cause no specific complaints, but thrombosis in the presence of an arteriovenous fistula may produce severe symptoms such as massive edema and pain. This is report of one patient, who developed massive edema of upper extremity and in whom proximal subclavian vein occlusion developed after previous percutaneous dialysis catheter. Right internal jugular vein to axillary vein bypass with 8mm PTFE provided prompt and effective venous outflow, with complete resolution of venous engorgement of the affected limb and preservation of the dialysis fistula.

BACKGROUND: Patients with spinal cord injury have a significant degree of morbidity and mortality caused by renal disease. Tubulointerstitial form of renal disease with minimal proteinuria predominate in this population. A retrospective study was performed to investigate the risk factors that may contribte to the development of proteinuria in patient with chronic spinal cord injury. METHODS: Between December 1999 and May 2000, 40 spinal cord injury patient in Korean Veterans Hospital were recurited retrospectively into the study. The information was gathered included medical record, laboratory data, and radiological study. RESULTS: Proteinuric subjects were older, had a longer duration of injury, had undergone a greater number of decubitus ulcer procedures and hydronephrosis. CONCLUSION: Proteinuria in the patients with spinal cord injury was related to the increase of the therapy for the decubitus ulceration, hydronephrosis, and the duration of the spinal cord injury, and it developed significantly more in paraplegia patients than in quadriplegia patients, which might be due to the more duration of the spinal cord injury in paraplegia patients. Therapeutic efforts directed toward preserving renal function should focus on avoidance of hydronephrosis, and decubitus ulceration.
