Double pituitary neuroendocrine tumors in a patient with normal growth hormone level acromegaly: A case report and review of the literature.

Background: Acromegaly is a rare disease caused by growth hormone (GH) hypersecretion caused by a pituitary neuroendocrine tumor (PitNET). However, some acromegaly patients show normal GH levels, and they can be a pitfall in clinical diagnosis. Moreover, rarely, synchronous true double or multiple PitNETs are encountered.

A Case of Nervus Intermedius Neuralgia.

Background: Nervus intermedius neuralgia is an extremely rare craniofacial neuralgia characterized by paroxysmal episodes of pain located deep in the ear, typically triggered by sensory or mechanical stimuli at the wall of the auditory canal without underlying pathology. Pain is sometimes associated with disorders of lacrimation, salivation, and taste.

Case Description: We present a case of a surgically treated 68-year-old man with left paroxysmal deep ear pain for 20 years before presentation.

Lemierre Syndrome Associated with Ipsilateral Recurrent Laryngeal Nerve Palsy: A Case Report and Review.

Lemierre syndrome (LS) is a rare life-threatening disease that is often caused by an acute oropharyngeal infection with a secondary thrombophlebitis of the internal jugular vein. LS rarely manifests as cranial nerve palsy. To the best of our knowledge, this is the second case report of LS associated with recurrent laryngeal nerve palsy.

Oxidative stress controlling agents are effective for small intestinal injuries induced by non-steroidal anti-inflammatory drugs.

Background And Aim: Video-capsule endoscopy (VCE) has shown that intestinal ulcers are common in non-steroidal anti-inflammatory drugs (NSAIDs) users, although the mechanisms and management have not been clearly defined. To explore the contribution of oxidative stress and potential of anti-oxidants for NSAIDs-induced intestinal ulcers, we assessed human serum oxidative stress balance and the effect of anti-oxidants using a mouse model.

Methods: A total of 30 NSAIDs users (17 aspirin and 13 non-aspirin users) received VCE.

Oxidative stress balance is dysregulated and represents an additional target for treating cholangiocarcinoma.

Background: Pancreatico-biliary malignancies exhibit similar characteristics, including obesity-related features and poor prognosis, and require new treatment strategies. Oxidative stress is known to induce DNA damage and carcinogenesis, and its reduction is viewed as being favorable. However, it also has anti-infection and anti-cancer functions that need to be maintained.

Recurrence after radiotherapy for gastric mucosa-associated lymphoid tissue (MALT) lymphoma with trisomy 18.

A 36-year-old Japanese woman presented with extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the stomach. The gastric lesions only partially improved after eradication therapy for Helicobacter pylori. A fluorescence in situ hybridization analysis revealed no fusion genes of API2-MALT1, although trisomy of chromosome 18 was identified.

L-carnitine prevents progression of non-alcoholic steatohepatitis in a mouse model with upregulation of mitochondrial pathway.

Non-alcoholic steatohepatitis (NASH) is a severe form of non-alcoholic fatty liver disease characterized by lobular inflammation, hepatocellular ballooning, and fibrosis with an inherent risk for progression to cirrhosis and hepatocellular carcinoma (HCC). Mitochondrial dysfunction appears to play a role in the progression from simple steatosis to NASH. L-carnitine (L-b-hydroxy-g-N-trimethylaminobutyric acid), an essential nutrient that converts fat into energy in mitochondria, has been shown to ameliorate liver damage.

Characteristics of serious complicated gastroduodenal ulcers in Japan.

Background/aims: Even in Japan where the incidence of H. pylori infection is high, patients with gastroduodenal ulcers caused by NSAIDs are on the increase. A prospective study was conducted to elucidate the characteristics of gastroduodenal ulcers complicated with ulcerous hemorrhage and perforation among Japanese.

[A case of hemolytic uremic syndrome after adjuvant chemotherapy with gemcitabine in a patient with pancreatic cancer].

A 63-year-old man with Stage IVa pancreas tail cancer was admitted for a distal pancreatectomy and splenectomy; adjuvant chemotherapy with gemcitabine was also administered. The chemotherapy was terminated after 16 courses due to hemolytic anemia, thrombocytopenia and renal dysfunction. Plasma exchange was performed; however the patient's renal function was diminished, requiring chronic hemodialysis.

Basal protrusion of ulcers induced by endoscopic submucosal dissection (ESD) during treatment with proton pump inhibitors, and the suppressive effects of polaprezinc.

Background/aims: When a peptic ulcer is treated with proton pump inhibitors (PPI), protrusion of the ulcer base is sometimes noted during ulcer healing. To clarify the incidence of ulcer base protrusion in ulcers induced by endoscopic submucosal dissection (ESD), and whether the addition of polaprezinc, a cytoprotective agent used for treatment of gastric ulcer, to the PPI regimen helps to suppress it.

Methodology: One hundred sixty-three patients on which ESD was performed were randomly allocated to either two groups: one treated with lansoprazole (30mg/day) and the other with lansoprazole (30mg/day) plus polaprezinc (150mg/day) for the treatment of ESD-induced ulcer.

[Autoregulation of dynamic cerebral blood flow during hypotensive anesthesia with prostaglandin E1 or nitroglycerin].

Background: Autoregulation of dynamic cerebral blood flow during hypotensive anesthesia is unclear. We examined the effects of hypotensive anesthesia with prostaglandin E1 (PGE1) or nitroglycerin (NTG) on autoregulation of the dynamic cerebral blood flow.

Methods: Beat-by-beat mean arterial pressure (MAP) and blood flow velocity in the middle cerebral artery were measured before and during hypotensive anesthesia.

[Dynamic cerebral blood flow autoregulation during sevoflurane anesthesia and TIVA].

Background: Dynamic cerebral blood flow autoregulation during sevoflurane anesthesia and total intravenous anesthesia (TIVA) is unclear. We examined the cerebral circulation autoregulation during anesthesia by sevoflurane or TIVA.

Methods: We measured mean blood pressure (MBP) and blood flow velocity of the middle cerebral artery by a transcranial Doppler ultrasonography before and during anesthesia using sevoflurane (volatile induction and maintenance of anesthesia (VIMA) group) and using propofol and fentanyl (TIVA group), and the relationship between changes in MBP and cerebral blood flow velocity was evaluated using the method of transfer function analysis.
