Secondary amyloidosis is an occasional complication of ankylosing spondylitis (AS) and in most cases renal amyloidosis presents with proteinuria, nephrotic syndrome and decreased renal function. We describe a 32-year-old male patient with AS manifested by frequent diarrhea, intermittent abdominal pain and low serum albumin levels. He has suffered from severe inflammatory back pain for 14 years with multiple peripheral joint involvement. Protein-losing enteropathy due to gastrointestinal amyloidosis was diagnosed with 99mTc-human albumin scintigraphy, fecal alpha-1 antitrypsin clearance and colonoscopic biopsy with Congo red staining. Somatostatin analogue octreotide and prednisolone were introduced with successful result.

Rapid opiate detoxification (ROD) is a technique whereby the opiate-dependent patient is withdrawn acutely, under anesthesia, from the opioid. Following detoxification, patients experience severe back pain and restlessness often accompanied by a restless-leg-syndrome. We evaluated gabapentin given immediately following detoxification to attenuate these symptoms. In addition, we evaluated the use of the somatosensory-evoked potential (SEP) as a parameter to quantitate pain responses. Patients (n=21; mean age 32.5 +/- 7 SD; 12 males, 9 females) underwent ROD with naltrexone (2 x 50 mg) during propofol anesthesia and artificial ventilation (IPPV). Sympathetic overshoot was attenuated by clonidine, and increased bowl movement was managed by continuous i.v. somatostatin. Back pain, restlessness, and restless-leg-syndrome were treated with gabapentin (1200 mg) in the ICU. Efficacy was assessed by the patient's subjective ratings of restlessness (0-4). In addition, measurements of amplitude (microV), latency (ms) of late N100-peak of the somatosensory evoked potential (SEP), and tolerance to an increased electrical nociceptive stimulus (mA) to the forearm were performed. Data were compared to pre-treatment control and to the period shortly after detoxification. From a mean of 8.4 +/- 2.5 microV, N100-peak increased to a mean of 12.3 microV +/- 3.3 (p < 0.005) following opioid detoxification. Gabapentin reduced amplitude height to a mean of 3.5 +/- 1.5 microV. Also, tolerance to nociceptive stimulus, which had dropped to 4.4 mA, increased to 12.5 mA (p < 0.01), while intensity for restlessness and thrashing of limbs dropped from 3.2 to 1.2 (p < 0.05). The sudden displacement of the opiate from its receptor site induced by naltrexone, resulted in a post inhibitory SEP overshoot with an increase in nociceptive afferent volleys, and a lowering in pain threshold. This was associated with back pain, limb thrashing and a restless-leg-syndrome, all of which could be attenuated by gabapentin. The amplitude of late N100-peak parameter appears to be a potential candidate to quantify the increase of nociception in such patients.

A 24-year-old female complaining of diarrhea and back pain was admitted to hospital where a tumor of the pancreatic head was revealed on a computed tomography (CT) scan. Abdominal ultrasonography, CT and celiac angiography revealed a hypervascular lesion on the pancreas. An endocrine tumor, particularly a somatostatinoma, was suspected and hormone levels in the blood were examined. Serum hormone levels were normal, so FDG-PET was performed. An abnormally high accumulation of FDG was detected on the FDG-PET image at the head of the pancreas, and the SUV of the lesion was 3.2, so the mass was considered to be malignant on FDG-PET. Pylorus-preserving pancreatoduodenectomy was performed with a preoperative diagnosis of malignant endocrine tumor. The resected specimen revealed a massive, yellowish-white tumor of the pancreas head measuring 50x 45x38mm. Histologically, the tumor was a malignant islet-cell tumor, and immunohistochemically the tumor stained with an anti-somatostatin antibody, but not with antibodies against glucagons, insulin or vasoactive intestinal polypeptide. The patient was discharged after the operation and has remained well without recurrence for 5 years. Liver metastatic tumors, however, appeared 6 years after the operation.

We report on a 62-year-old man with metastatic prostate cancer (cT3b N1) diagnosed in 2011, treated with total androgen blockage with flutamide and goserelin acetate (Zoladex). He presented with left suprascapular swelling and low-back pain after being asymptomatic for 5 years. His prostate-specific antigen was 0.049 ng/mL. F-NaF PET-CT and Ga-PSMA scan were negative, whereas Ga-DOTA NOC scan done after 10 days showed multiple somatostatin-avid hepatic and lymph node metastasis.
