Vaginal sling implant misdiagnosed as rectal subepithelial tumor

As cosmetic procedures receive increasing attention from the media, female genital cosmetic surgery (FGCS) has become quite popular in Korea. The safety and efficacy of these surgeries and procedures have yet to be thoroughly documented. We report a case of a 47-year-old woman who underwent a vaginal sling implantation, which resulted in the misdiagnosis of a rectal subepithelial tumor during endoscopic mucosal resection (EMR). This patient suffered an iatrogenic rectal perforation during the EMR, which necessitated an exploratory operation. The sling implant was removed via the vaginal approach, and a primary repair of the vaginal and rectal walls was performed. The patient subsequently showed no sign of complication at her 6-month follow-up. Patients need to be educated about the importance of reporting a history of FGCS prior to undergoing surgical or endoscopic procedures. Also, physicians have to check the medical history of patient thoroughly to avoid misdiagnoses and unnecessary treatment.

A Case of Polyarthritis Associated with Reactivation of Chronic Hepatitis B Virus Infection

Hepatitis viruses (hepatitis B virus (HBV) and hepatitis C virus) have been associated with development of inflammatory arthritis. Approximately 400 million people worldwide have chronic HBV infection. HBV infection is the one of the most common causes of liver disease, and the prevalence of HBV infection in Korea is almost 6%. Arthritis in patients with HBV can be encountered in two settings: as a rheumatoid arthritis (RA)-like, acute, self-limited polyarthritis during the pre-symptomatic phase of acute hepatitis B, or, more rarely, as arthritis occurring in the context of HBV-associated polyarteritis nodosa (PAN). In both cases, the pathogenesis of arthritis is attributed to the deposition of immune complexes containing viral antigens (HBsAg or HBeAg) and their respective antibodies (anti-HBs and anti-HBe) in synovial tissues. Here we report on a case of polyarthritis associated with reactivation of chronic hepatitis B virus infection with a review of the literature.

Multifocal Motor Neuropathy with Conduction Blocks During TNF-alpha Antagonist Therapy in a Patient with Spondyloarthropathy

Tumor necrosis factor (TNF)-alpha antagonist has been proven to have benefit for rheumatologic diseases. Because TNF-alpha is not only an important mediator of inflammation in human body, but plays many physiologic roles, it can cause unique adverse effects or complications related to these functions. Adverse effects involving neurological systems, such as Guillain-Barre syndrome, Chronic inflammatory demyelinating polyneuropathy, multifocal motor neuropathy with conduction blocks (MMNCB), distal symmetric polyneuropathy, and small fibers neuropathy have been previously reported. However, only several cases of infliximab-associated MMNCB are reported. We report a case of MMNCB which developed while treating spondyloarthropathy with infliximab.

A Case of Renal and Liver Abscesses Caused by Nalidixic Acid-Resistant Salmonella typhi / 대한내과학회지

Prompt antibiotic treatment reduces the incidence of complications such as liver abscesses, pyelonephritis, and osteomyelitis in patients with typhoid fever. Renal or liver abscesses are especially rare in patients without underlying disease or predisposing factors. The occurrence of both renal and liver abscesses in a patient with typhoid fever has not been reported. Although the prevalence of typhoid fever in Korea has decreased, it is still an important disease owing to increased opportunities for the occurrence of waterborne diseases with climate warming and group feeding, and the increased numbers of tourists and foreigners visiting Korea. We present a patient with no underlying disease or predisposing factors who developed both renal and liver abscesses caused by nalidixic acid-resistant Salmonella typhi after a trip to Nepal. He was treated successfully with percutaneous drainage of the renal abscess and high-dose ciprofloxacin.

Comparison Korean National Health Insurance Reimbursement and Other Guidelines for TNF-alpha Blocker in Rheumatoid Arthritis

OBJECTIVE: The aim of this study was to examine how many Korean rheumatoid arthritis (RA) patients fulfilling the 2008 American College of Rheumatology (ACR) recommendation, 2007 British Society for Rheumatology (BSR) guideline and 2010 Japan College of Rheumatology (JCR) guideline for TNF-alpha blocker, meet the Korean National Health Insurance reimbursement criteria and to evaluate the reasons for failing the Korean National Health Insurance reimbursement criteria. METHODS: Data were obtained from a registry of RA patients who visited rheumatology clinics of Hallym university affiliated hospitals. Patients who were previously prescribed with methotrexate or leflunomide for more than 3 months and had at least one DAS28 examination were included in the present study. RESULTS: Of 642 patients included, 118 episodes meeting ACR guideline for using TNF-alpha blocker were identified in 88 patients (13.7%). In addition, 19 episodes meeting BSR guideline in 17 patients (2.6%) and 21 episodes meeting JCR guideline in 21 patients (6.2%) were identified. Four episodes (4.8%) meeting ACR recommendation, 0 episodes meeting BSR criteria and 5 episodes (12%) meeting JCR criteria, respectively, were eligible for TNF-alpha blocker according to the Korean National Health Insurance reimbursement guideline. The most common reason for failing the Korean National Health Insurance reimbursement criteria was the number of active joint counts (92.6%). CONCLUSION: Our results show that the majority of RA patients satisfying the ACR guideline, BSR and JCR guideline for use of the TNF-alpha blocker did not meet the Korean National Health Insurance reimbursement criteria. Patients most often failed due to active joint count criteria.

A Case of Hemocholecystitis in a Patient with Microscopic Polyangiitis / 대한내과학회지

Microscopic polyangiitis (MPA) is a systemic necrotizing vasculitis, primarily associated with rapidly progressive glomerulonephritis and alveolar hemorrhage. Approximately 50% of MPA cases are associated with gastrointestinal involvement, but rarely do cases involve the gall bladder. We report an unusual case of MPA complicated by hemocholecystitis. A 62-year-old woman was admitted to our hospital with rapidly progressive renal dysfunction and pneumonia unresponsive to antibiotics. A chest CT scan showed bilateral diffuse alveolar consolidation, and perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) staining was positive. During the course of hospitalization, the patient complained of severe abdominal pain, and an abdominal CT scan revealed acalculous cholecystitis with hemorrhage. Cholecystectomy was performed, and a gall bladder biopsy revealed fibrinoid necrosis of small arteries without granuloma. Cholecystitis should be considered in patients with unexplained upper abdominal pain and MPA.

A Case of Toxoplasma Lymphadenitis / 감염

Toxoplasma lymphadenitis is the most common clinical manifestation of toxoplasmosis in an immunocompetent host. In foreign countries, it is a relatively common etiology of reactive hyperplasia of lymph nodes, but it is still rare in Korea. The cervical lymph nodes are the most commonly involved, whereas systemic manifestations are rare. We are reporting a case of toxoplasma lymphadenitis in an immunocompetent host. A 31-year-old man was admitted to the hospital because of submandibular lymph node enlargement for 3 months. Toxoplasma lymphadenitis was diagnosed by positive IgG and IgM toxoplasma antibody titer and specific pathologic findings of submandibular lymph node, such as reactive follicular hyperplasia, epitheioid histiocytes in the interfollicular area, and infiltrations of subcapsular monocytoid B lymphocytes. In Korea, travels to and from other countries and contacts with foreigners are increasing, possibly increasing the incidence of toxoplasma lymphadenitis, which should be considered in the differential diagnosis of lymphadenitis.
