Page kidney after botulinum toxin injection during chiropractic care / 영남의대학술지

Page kidney refers to the phenomenon of hypertension secondary to long-standing compression of renal parenchyma caused by renal subcapsular collection. The most common cause of renal subcapsular collection is a hematoma which usually occurs after a history of blunt trauma. A 42-year-old female patient who received botulinum toxin injection in her back during chiropractic care was admitted to the emergency room with sudden bilateral flank pain and hypertension. The computed tomography (CT) images demonstrated the presence of bilateral subcapsular renal hematoma. The patient was treated conservatively and recovered well. The follow up CT images showed markedly resolved bilateral hematoma.

Diabetic Ketoacidosis with Spontaneous Pneumomediastinum: A Case Report / 임상당뇨병

Spontaneous pneumomediastinum (SPM) is defined as the presence of extraluminal gas in the mediastinal space without any clear traumatic cause. It has been reported in association with asthma exacerbation, emesis, childbirth, seizure, excessive shouting, drug inhalation and diabetic ketoacidosis (DKA). SPM complicated by DKA is infrequently accompanied with chest pain and DKA can lead to changes in respiratory rate and depth; this complication might be underestimated. Here, we report a 21-year-old male with throat pain on swallowing due to SPM complicated by DKA. Clinicians need to consider this complication in differential diagnoses.

Idiopathic hypereosinophilic syndrome presenting with urinary frequency, abdominal pain, and diarrhea

Idiopathic hypereosinophilic syndrome (IHES) is a rare disorder defined by persistent blood eosinophilia, evidence of eosinophil-associated organ dysfunction and absence of secondary causes. Eosinophilic infiltration and its mediator release can cause damage to multiple organs. Although IHES can involve every organ system, bladder involvement is rarely evidenced. We recently reported a case of IHES with both bladder and gastrointestinal tract involvement. A 43-year-old woman visited Hallym University Sacred Heart Hospital complaining of urinary frequency, abdominal pain, and diarrhea for several months. Abdominal pelvic computed tomographic scan showed diffuse wall thickenings in her bladder and colon with small pelvic ascites. Laboratory investigation showed a marked peripheral eosinophilia and tissue biopsies confirmed eosinophilic infiltration in the bladder wall, esophagus, and duodenum. The patient was treated with prednisolone and her eosinophilia and symptoms have gradually improved.

A Case of Hepatitis B Virus Reactivation in a HBsAg-Negative and Anti-HBs-Positive Patient with Diffuse Large B-Cell Lymphoma after Rituximab plus CHOP Chemotherapy

The reactivation of hepatitis B virus (HBV) is well known complication among lymphoma patient related with chemotherapy. Rituximab is monoclonal antibody that targets B-lymphocytes for treatment of lymphoma and it increases reactivation of HBV. Although most of reactivation occurs in HBV carrier, it can also rarely occur when hepatitis B surface antigen (HBsAg) is negative. Furthermore it is less frequently reported in lymphoma patient when HBV serology shows HBsAg is negative and anti-HBs is positive. We report a case of HBV reactivation following 6 cycle of rituximab plus CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone) chemotherapy for diffuse large B-cell lymphoma in HBsAg negative/anti-HBs positive 58-year-old male, with a review of the literature.

A Case of Hyponatraemic Seizure Following Terlipressin Therapy for a Variceal Hemorrhage in a Patient with Liver Cirrhosis / 대한내과학회지

Terlipressin has splanchnic vasoconstrictive effects, and is generally used for the management of gastroesophageal variceal bleeding secondary to liver cirrhosis. Terlipressin is a synthetic arginine vasopressin (AVP) analog containing a nonapeptide sequence. Terlipressin has increased selectivity for the V1 receptor, compared with AVP; hence, it is considered to be a safe vasoconstrictor. However, side effects such as hyponatremia and seizure, although very rare, have been reported. Hyponatremia related to terlipressin may be caused by the syndrome of inappropriate antidiuresis (SIAD), which is a disorder of sodium and water balance characterized by hypotonic hyponatremia without elevation of the antidiuretic hormone level. Here, we report a case of hyponatremic seizure induced by an infusion of terlipressin in a 52-year-old female who had isolated gastric variceal bleeding secondary to alcoholic liver cirrhosis.
