    An improved knowledge of the natural history is the indispensible basis for a rational concept in regard to the diagnosis, classification, understanding and management of pain in chronic pancreatitis. Unfortunately, data on the natural history of CP are scarce and conflicting. Some relevant observations of our prospective long-term study of a mixed medical-surgical cohort comprising 207 patients with alcoholic CP (mean follow-up 17 years from onset) are summarized. In early-stage CP, episodes of recurrent pancreatitis were predominant. Severe persistent pain was typically associated with local complications (mainly postnecrotic cysts in 54%; symptomatic cholestasis in 24%) relieved definitely by a drainage procedure. Lasting pain remission was documented in >80% of the whole cohort within 10 years from onset in association with marked pancreatic dysfunction. From our experience, the relief of "chronic" pain regularly follows selective surgery tailored to the presumptive pain cause or it occurs spontaneously in uncomplicated advanced CP (excluding narcotic addiction).

    Objective The purpose of this study was to investigate whether this semiquantitative measurement of the motor end-plate acetylcholine receptors (AChRs) can be used to confirm the diagnosis of myasthenia gravis (MG), and in particular ocular MG.
    Methods Motor point biopsies were performed from the biceps brachii muscles. Measurement of AChRs was made in peroxidase-labeled cc-bungarotoxin stained muscle specimens.
    Patients Twenty patients with ocular MG, 37 with generalized MG, 5 with Lambert-Eaton myasthenic syndrome, 3 with botulism, 8 with amyotrophic lateral sclerosis, and 8 controls were included in this study.
    Results AChRs were decreased in all patients with generalized MG and in 80% of ocular MG including patients without detectable circulating anti-AChR antibodies, as compared with the control subjects.
    Conclusion This method is useful to confirm the diagnosis of MG, in particular ocular MG without detectable anti-AChR antibodies.

    Recently, hepatitis virus-associated chronic hepatitis or cirrhosis has been suggested to be involved in the pathogenesis of Cholangiocarcinoma (CC). A 52-year-old man was diagnosed as CC with a background of hepatitis B virus (HBV)-dependent cirrhosis. A minute hepatic tumor was found during the follow-up, and was diagnosed as CC on percutaneous biopsy. The patient died of hepatic failure and an autopsy revealed the tumor to be a well to moderately differentiated adenocarcinoma. An immunohistological analysis of HBV X gene-encoded protein (HBX) was neither detected in the cancerous nor in the noncancerous tissue. No oncogenic role of the virus was verified in this case.

    We report a patient with insulinoma associated with Zollinger-Ellison syndrome. A 67-year-old woman was first admitted to our hospital for an abdominal mass. Abdominal computed tomography (CT) revealed a large pancreatic tumor, which was then diagnosed as an unresectable pancreatic adenocarcinoma. At the age of 71, she presented symptoms of hypoglycemia. Fasting blood glucose was 21 mg/dl and plasma immunoreactive insulin level was 846 μU/ml. Plasma gastrin, glucagon, vasoactive intestinal polypeptide and somatostatin levels were all normal. At the age of 73, hypoglycemic attacks occurred more frequently and she was admitted to our hospital. Abdominal CT scan showed multiple liver metastases. Chemotherapy with 5-fluorouracil and doxorubicin was performed. Three months later, she had an emergency laparotomy because of a perforated duodenal ulcer. Plasma gastrin level was 1, 960 pg/ml at that time. Gastric hypersecretion was well controlled with a proton pump inhibitor (lansoprazole) but she died of widespread cancer dissemination 8 years after her first admission. On autopsy, histologic examination revealed a mixed acinar-endocrine carcinoma of the pancreas. Immunohistochemical stains were positive for insulin, gastrin, and α1-antitrypsin.

    A 51-year-old man with a primary angiosarcoma of the right atrium is reported. The angiosarcoma was not detected by transthoracic echocardiography or computed tomography, but magnetic resonance imaging and transesophageal echocardiography did show the tumor of the right atrial free wall. We performed a transvenous endomyocardial biopsy of the tumor under the guidance of transesophageal echocardiography and made the pathological diagnosis. This case demonstrates the advantage of magnetic resonance imaging and transesophageal echocardiography for tumor detection over transthoracic echocardiography and computed tomography and the usefulness of transesophageal echocardiography for guiding the right atrial endomyocardial biopsy procedure.

    We report cases of serious arrhythmias associated with apical hypertrophic cardiomyopathy (AHCM). Thirty-one patients were referred to our institute to undergo further assessment of their AHCM from 1988 to 1999. Three patients with nonsustained ventricular tachycardia demonstrated an 123I-MIBG regional reduction in the tracer uptake. In two patients with ventricular fibrillation (VF), the findings from 123I-MIBG imaging revealed regional sympathetic denervation in the inferior and lateral regions. Electrophysiologic study demonstrated reproducible induction of VF in aborted sudden death and presyncopal patients, resulting in the need for an implantable defibrillator device and amiodarone in each patient. Patients with refractory atrial fibrillation with a rapid ventricular response suffered from serious congestive heart failure. A prudent assessment and strategy in patients with this disease would be indispensable in avoiding a disastrous outcome.

    A 72-year-old man was treated for fungal tricuspid valve endocarditis (TVE) with significant tricuspid valvular regurgitation and severe congestive heart failure caused by Candida parapsilosis. The patient had received hyperalimentation and antibiotic therapy for three months through a central venous catheter after the surgical treatment of ileus. The patient was treated medically with amphotericin B and fluconazole because of high surgical risk due to severe pulmonary emphysema, and he responded well. Although TVE caused by C. parapsilosis is rare, we should consider this possibility in patients receiving long-term hyperalimentation and antibiotic therapy using a central venous catheter.

    MELAS is characterized by mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes, but cardiac involvement also frequently occurs. An 80-year-old female patient had been suffering from insulin-dependent diabetes mellitus and neurosensory hearing loss. At the age of 79 she suffered metabolic acidosis with persistent drowsiness and was subsequently found to have severe cardiac dysfunction. Muscle biopsy disclosed the presence of abnormal mitochondria, and the MELAS gene mutation (A3243G of the tRNALeu(UUR)) was demonstrated. It is noteworthy that this mitochondrial disease patient has survived until a great age, which shows the wide clinical spectrum of MELAS, especially in the age of onset.

    A 60-year-old man was diagnosed as adult T-cell leukemia with severe hypercalcemia because of production of parathyroid hormone-related protein. After admission, the patient had respiratory insufficiency with an infiltrative shadow in his lungs suggestive of pneumonia. However, neither improvement in respiratory function nor disappearance of the abnormal chest shadow was observed with administration of various antibiotics. An autopsy demonstrated the chest shadow had been caused by metastatic calcification associated with hypercalcemia due to production of parathyroid hormone-related protein. The possibility of metastatic calcification should be considered in patients with adult T-cell leukemia and hypercalcemia who have an abnormal chest shadow.

    A 21-year-old man presented persistent dry cough, general malaise, loss of appetite, decreased sexual desire and double vision. Chest radiograph revealed a mass shadow in the left upper lobe. Histopathological diagnosis of the tumor was squamous cell carcinoma. Brain computed tomography and magnetic resonance imaging revealed a metastasis to the pituitary gland. Hypopituitarism was diagnosed by pituitary function tests. Diabetes insipidus was absent and the function of the posterior lobe of the pituitary gland was preserved. Hypopituitarism due to pituitary metastasis is a rare complication of lung cancer, and has never been reported in a patient as young as 21 years old.

    Turner's syndrome is a condition involving total or partial absence of one X chromosome and has been associated with a number of diseases including non insulin dependent diabetes mellitus, abnormalities of glucose metabolism and hypothreosis. There have been many case reports in which Turner's syndrome is associated with type 2 diabetes, but the association with type 1 diabetes and/or life threatening complications is very rare. We present an unusual case of a patient with Turner's syndrome who has type 1 diabetes and is complicated with ketoacidosis, severe acute and recurrent pulmonary edema and rhabdomyolysis.

    A 48 years-old Japanese man suffered from marked xanthomas on ankles, knees, hand fingers, and foot joints due to insufficient control of serum hypercholesterolemia despite low density lipoprotein (LDL-C) absorptive therapy followed by treatment with potent anti-hypercholesterolemic agents. He had undergone surgical resection of xanthonia on the knee, foot and hand finger joints. Treatment with simvastatin returned the serum total cholesterol levels to nearly normal levels, followed by marked fluctuations. He subsequently experienced transient right-visual disturbance, and roentogenographic examination was performed. The patient was diagnosed as right-common carotid artery thrombosis. After the thrombotectomy of the right-common carotid artery, his visual power was markedly improved.

    A 58-year-old man developed proteinuria and renal dysfunction following pneumonia caused by methicillin-resistant Staphylococcus aureus (MRSA). Vancomycin was administered, and prednisolone pulse therapy and plasmapheresis were performed. Subsequently, serum creatinine was decreased. Eight months later, creatinine and CRP were again elevated, and MRSA was detected. Vancomycin was again administered and plasmapheresis was performed. However, renal function was not improved and continuous hemodialysis was initiated. This case indicates that complete eradication of MRSA is necessary to treat MRSA-associated glomerulonephritis, and if this is not attained, a permanent loss of renal function occurs.

    We describe a rare case of secondary amy loidosis associated with usual interstitial pneumonia (UIP), who died from spontaneous rupture of the amyloid spleen. A 68-yearold man was admitted to evaluate to his interstital lung disease. Chest radiography showed reticular shadow in bilateral lower lung fields. Two years later, he suddenly felt severe abdominal pain. In spite of maximum therapy, he died from hypovolemic shock. Postmortem examination revealed massive intraabdominal hemorrhage. The diagnosis of lung disease was UIP and amyloid A type deposits were observed in various organs including the ruptured spleen.

    Recently, various forms of Churg-Strauss syndrome (CSS) have been reported in association with the use of leukotriene receptor antagonists. A 53-year-old woman with a 5-year history of asthma associated with chronic sinusitis presented mononeuropathy, hypereosinophilia, and positive P-ANCA in October 1999. She had been treated with pranlukast (450 mg/day) and beclomethasone dipropionate (BDP) at a dose of 1, 200 μg/day which had gradually been tapered to 800 μg/day over the previous 17 months. She was found to have CSS, and 60 mg/day of prednisolone was administered instead of pranlukast, resulting in an improvement of her symptoms and eosinophilia. Later, we confirmed that serum P-ANCA had been positive before the pranlukast treatment, but CSS vasculitis had not appeared at that time. We speculated that an underlying incomplete form of CSS was being masked in this case and that the reduction of inhaled corticosteroid might have been responsible for the unmasking of CSS.

    A 57-year-old woman was hospitalized with malignant lymphoma of the right talus. After treatment, complete remission was obtained. Gallium-67 scintigraphy to confirm the remission demonstrated increased uptake in the whole body skeletal muscle, especially in her thighs. Biopsy of right gastrocnemius muscle showed epithelioid granuloma. Serum angiotensin-converting enzyme activity (ACE) and lysozyme had increased to several times the normal range. We diagnosed her disease as bone-associated sarcoidosis-lymphoma syndrome. Human herpes virus 8 (HHV-8) genome was examined in the bone marrow specimen, and the relationship between sarcoidosis-lymphoma syndrome and HHV-8 was discussed.

    We report a case of neurosyphilis with transient global amnesia (TGA)-like attacks on the first presentation. MRI abnormalities in bilateral limbic systems, including a few lesions in the basal ganglia and thalamus, were identified. Depression and dementia became apparent, accompanied by a high treponemal antibody titer and mild cortical atrophy. Antisyphilitic therapy brought about mild improvement, and the MRI abnormalities decreased.

    A 57-year-old man became unresponsive and mute with bilateral ophthalmoplegia and quadriplegia. Magnetic resonance imaging (MRI) showed bilateral infarctions at the ventral midbrain and the dorsomedial nucleus of the thalamus. Serial studies with MR and vertebral angiography disclosed hypoperfusion and spontaneous reperfusion of the bilateral posterior cerebral arteries at their origin from the basilar artery. Electroencephalographically, a posteriorly distributed alpha rhythm was clearly recorded and it was reactive in response to external stimuli. The findings seen in the present patient suggest that the ventral midbrain and medial dorsal thalamus are not necessary to produce posterior electroencephalographic alpha activity.

    A 38-year-old woman visited our hospital with edema on her face and conjunctivae. The underlying disease was not clarified, and she did not visit the hospital afterwards. She suffered from diarrhea, polyarthralgia, Raynaud's phenomenon, malar rash and hair loss in the subsequent two years, and was hospitalized because of hypoproteinemia. Her urine, liver and heart test results did not account for her hypoproteinemia. She was diagnosed as having protein-losing enteropathy (PLE) associated with SLE based on the 99mtechnetium-labeled human serum albumin scintigraphy findings, clinical findings and laboratory results of antinuclear and anti-Sm antibodies. This case report demonstrates a strong association between PLE and SLE because PLE was aggravated along with the appearance of SLE symptoms and PLE subsided with prednisolone treatment along with improvement of SLE.

    The prognosis of Mycobacterium avium complex (MAC) infection has been improved by new macrolides-containing regimens and the use of highly active antiretroviral therapy (HAART) in the treatment of acquired immunodeficiency syndrome (AIDS). We report on two AIDS cases with long lasting bacteremia due to MAC under this regimen. Both patients experienced problems due to side effects from the anti-MAC regimen and from an immune-reconstitution syndrome related to HAART. MAC infection persisted despite treatment, however, no anti-MAC drug-resistant isolates emerged throughout the clinical course in either case. These cases demonstrate that therapy for disseminated MAC infection is sometimes difficult even with HAART and macrolides-containing regimens.
