Paradoxical response as a cervical lymph node enlargement after termination of anti-tuberculosis treatment in a patient with pulmonary tuberculosis / 고신대학교의과대학학술지

A paradoxical response is not uncommon in non-HIV-infected patients, particularly those with extra-pulmonary tuberculosis. It is defined as the radiological and clinical worsening of a previous lesion or the development of new lesion during anti-tuberculosis therapy. The paradoxical response has been attributed to host immunologic reactions, such as a delayed hypersensitivity or a response to mycobacterial antigens. In most reports of paradoxical response, these responses occurred in the same location as a previous lesion. In this patient with pulmonary tuberculosis, cervical lymph node enlargement occurred as a paradoxical response after the completion of anti-tuberculosis treatment. Although the new lesion developed in another location, it could be considered as a paradoxical response based on the negative culture result of acid fast bacilli from the new lesion and drug sensitivity result from initial bronchoalveolar lavage specimen. Therefore we were able to decide on the termination of unnecessary anti-tuberculous treatment. Based on our case, we can conclude that paradoxical response can occur after the termination of anti-tuberculosis therapy even in new site.

A Case of Fulminant Type 1 Diabetes during Pregnancy / 임상당뇨병

Fulminant type 1 diabetes is characterized by acute onset, no evidence of islet-related autoantibodies, low glycated hemoglobin(HbA1c) level at onset, and metabolic complications such as diabetic ketoacidosis. Fulminant type 1 diabetes development during pregnancy can result in severe maternal and fetal complications. Most of the patients with fulminant type 1 diabetes during pregnancy have been reported in Japan. In Korea, reports of fulminant type 1 diabetes during pregnancy are uncommon. We report a 36-year-old Korean woman with fulminant type 1 diabetes developed at 32 weeks of gestation who demonstrate a good outcome.

A Case of Biliary Fascioliasis Mimicking Neoplasia of the Common Hepatic Duct / 대한내과학회지

Fascioliasis is a rare zoonotic disease caused by Fasciola hepatica, the liver fluke. Humans can become accidental hosts of this parasite by ingesting contaminated drinking water or plants containing viable metacercariae. There are two disease stages: the hepatic (acute) and biliary (chronic) stages. The biliary stage of this zoonotic infection is often misdiagnosed because the symptoms are subclinical, with intermittent cholangitis as the only sign. Endoscopic retrograde cholangiopancreatography (ERCP) has been described in the diagnosis of a few cases of fascioliasis. We used this modality to diagnose biliary fascioliasis in a 39-year-old woman with chronic hepatitis B who had intermittent abdominal pain for three years with irregular wall thickening and luminal narrowing of the common hepatic duct (CHD), which resembled neoplasia of the CHD. Following the correct diagnosis, the adult worm was removed using endoluminal forceps via endoscopic sphincterotomy. This case report confirms the diagnostic and therapeutic value of ERCP in patients with biliary fascioliasis that may mimic neoplasia of the CHD.
