A patient with carcinoid tumor of the head of pancreas and carcinoid syndrome presented without liver metastasis. The patient had retroperitoneal lymphadenopathy. He had symptoms of flushing, diarrhea and abdominal pain. 5-Hydroxyindoleacetic acid (5-HIAA) was elevated. Absence of liver metastasis was documented not only by the negative computed tomography (CT) scan and liver/spleen scan, but also by autopsy. Except for carcinoid arising from ovary, testis, or bronchi, the other carcinoid tumors rarely cause carcinoid syndrome without liver metastasis. The literature was reviewed, and the findings are presented.

A double-blind controlled, randomized, parallel, multicenter 12-week study was conducted to compare the antihypertensive efficacy of lisinopril with that of metoprolol in treatment of moderate to severe hypertension. Initially, 118 patients were recruited on lisinopril and 61 on metoprolol; and for the purpose of efficacy analysis at week 8, 115 patients on lisinopril and 60 on metoprolol were included. The doses of lisinopril or metoprolol were 40-80 mg/day and 100-200 mg/day, respectively. At week 4, the pretreatment diastolic blood pressure of 111 mm Hg was decreased to 97 mm Hg (p less than 0.01) with lisinopril: metoprolol decreased the diastolic blood pressure from 110 to 99 mm Hg (p less than 0.01). Similar decreases were noted at week 8; however, the drop in blood pressure with lisinopril was not significantly different from that with metoprolol. Systolic blood pressure also demonstrated a decrease of about 18 mm Hg with lisinopril and 12 mm Hg with metoprolol (p less than 0.01). This larger decrease in systolic blood pressure with lisinopril was statistically significant at week 4 (p less than 0.05). These decreases in systolic blood pressures were maintained at week 8, again with statistical significance (p less than 0.01). Of the 118 lisinopril-treated patients, four were discontinued from lisinopril therapy because of headache, dizziness, rash, flushing, or lymphadenopathy. Four patients out of 61 (9.8%) were discontinued from metoprolol therapy because of fatigue, somnolence, asthenia, weight gain, flatulence, tremor, or bronchospasm. In conclusion, lisinopril 40-80 mg once daily is as effective as metoprolol 100-200 mg once daily in reducing diastolic blood pressure in patients with moderate to severe hypertension.(ABSTRACT TRUNCATED AT 250 WORDS)

Glatiramer acetate, formerly known as copolymer 1, is a mixture of synthetic polypeptides composed of four amino acids. Glatiramer acetate has been shown to be effective in preventing and suppressing experimental autoimmune encephalitis (EAE), the animal model of multiple sclerosis (MS). Therefore it was tested in several clinical studies, where it was found to slow the progression of disability and to reduce the relapse rate and the magnetic resonance imaging (MRI)-defined disease activity and burden in relapsing-remitting MS. As a daily standard dose, 20mg of glatiramer acetate is injected subcutaneously. After injection, glatiramer acetate undergoes rapid degradation to amino acids and shorter peptides; so it is not possible to measure any systemic plasma concentrations or excretion rates. Two major mechanisms have been proposed to explain the effects of glatiramer acetate in EAE and MS: the induction of glatiramer acetate-reactive T helper 2 (Th2)-like regulatory suppressive cells and the interference with T cell activation as an altered peptide ligand. The most common adverse effects were mild injection site reactions (erythema, inflammation and induration). The most remarkable adverse event is the acute and transient immediate postinjection reaction manifested by flushing, chest tightness, palpitations and dyspnoea. Other reported adverse effects are transient chest pain and lymphadenopathy. Antibodies to glatiramer acetate induced during treatment do not interfere with its clinical effects. In several controlled clinical studies, glatiramer acetate has been shown to provide consistent, reproducible clinical benefits in the target population of patients with relapsing-remitting MS. The safety profile and risk-benefit ratio are excellent. Overall, glatiramer acetate is very well tolerated and has an excellent risk-benefit profile in patients with relapsing-remitting MS.

Viruses cause most forms of encephalitis. The two main types responsible for epidemic encephalitis are enteroviruses and arboviruses. The City of New York reports about 10 cases of encephalitis yearly. Establishing a diagnosis is often difficult. In August 1999, a cluster of five patients with fever, confusion, and weakness were admitted to a community hospital in Flushing, New York. Flaccid paralysis developed in four of the five patients, and they required ventilatory support. Three, less severe, cases presented later in the same month. An investigation was conducted by the NewYork City (NYC) and New York State (NYS) health departments and the national Centers for Disease Control and Prevention (CDC). The West Nile virus (WNV) was identified as the etiologic agent. WNV is an arthropod-borne flavivirus, with a geographic distribution in Africa, the Middle East, and southwestern Asia. It has also been isolated in Australia and sporadically in Europe but never in the Americas. The majority of people infected have no symptoms. Fever, severe myalgias, headache, conjunctivitis, lymphadenopathy, and a roseolar rash can occur. Rarely, encephalitis or meningitis is seen. The NYC outbreak resulted in the first cases of WNV infection in the Western Hemisphere and the first arboviral infection in NYC since yellow fever in the nineteenth century. The WNV is now a public health concern in the United States.

Patients with clinically evident medullary thyroid cancer should have a total extracapsular thyroidectomy with bilateral central neck dissection and an ipsilateral prophylactic or therapeutic modified (functional) radical neck dissection when the primary tumor is greater than 1 cm and when the central neck nodes are positive. A prophylactic contralateral neck dissection should be done when the primary tumor is bilateral and when there is extensive lymphadenopathy on the side of the primary tumor. Patients who have gross, unresectable residual medullary thyroid cancer should receive postoperative external radiotherapy. Patients who are carriers of germ-line RET proto-oncogene point mutations or have an elevated (basal or stimulated) calcitonin levels on screening should have a prophylactic total thyroidectomy before age 6 years. In patients with an elevated basal or stimulated plasma calcitonin level and an intrathyroidal nodule on ultrasound, a total thyroidectomy and central neck lymph node dissection should be done. Patients with persistent or recurrent medullary thyroid cancer should have a complete thyroidectomy (if not done initially) and bilateral central and modified radical neck dissection, including upper mediastinal lymphadenectomy. Patients who are symptomatic from distant medullary thyroid cancer metastases (diarrhea, flushing, weight loss, or bone pain) should be treated with somatostatin analogs. Bone metastases should be resected if possible, and symptomatic lesions that are unresectable should be treated with external radiotherapy. Cytoreductive procedures such as radiofrequency ablation or cryoablation for liver metastases should be considered in symptomatic patients to reduce tumor burden. Localized pulmonary metastases should be resected. Chemotherapy or radioactive immunotherapy (iodine 131 labeled carcinoembryonic antigen monoclonal antibody) protocols should be considered in patients with nonoperative widely metastatic progressing medullary thyroid cancer.

A 41-year-old woman presented with a 2-month history of pruritus and a generalized dermatitis that developed initially on the head and spread to the trunk, legs, and buttocks. The pruritus caused extreme discomfort and was not relieved by antihistamines or topical steroid treatment. The patient denied flushing, syncope, and vomiting. Her medical history included asthma treated with salmeterol/fluticasone propionate inhaler, and status post silicone breast augmentation. Physical examination revealed a papular dermatitis on the trunk and extremities composed of lesions up to 0.5 cm in diameter, surrounded by excoriation marks (Figure 1). There was no hepatosplenomegaly or lymphadenopathy. Darier's sign was negative. Results of complete blood count, peripheral blood film examination, and liver function tests were all with normal limits. A biopsy specimen taken from a lesion and stained with hematoxylin-eosin showed telangiectasias, with an increased number of mast cells around blood vessels (Figure 2). Positive Giemsa (Figure 3) and c-kit stain (Figure 4) indicated an increased number of mast cells. Bone marrow aspiration and total body CT performed to rule out systemic involvement showed no pathology. Protein electrophoresis was normal. Serum tryptase and histamine were within normal limits, and 24-hour urine collection for histamine was normal. Narrow-band UV-B treatment was begun 3 times weekly, reduced to twice weekly after 2 months, and then stopped. The first few treatments resulted in significant relief of the pruritus and regression of lesions. After 3 months without treatment, the patient remained free of pruritus and lesions.

A 69-year-old female with rheumatoid arthritis was admitted to our hospital with facial flushing and cervical lymphadenopathy on Jan, 2006. She had been treated with methotrexate (MTX), sulfasalazine (SSA) and prednisolone. The MTX and SSA were discontinued because of appetite loss just before admission. The patient's white blood cell count was 30100/microl with 32.5% of plasma cells, and 25.7% of plasma cells were observed in the bone marrow. Immunoelectrophoresis revealed polyclonal hypergammaglobulinemia on admission. Flow cytometry analysis revealed that the plasma cells in the bone marrow expressed CD38 and CD19 and did not express CD56. The lymphadenopathy and the increase of plasma cells in the peripheral blood and the bone marrow gradually decreased after the cessation of MTX and SSA.

The patient was a 51-year-old man who had been prescribed carbamazepine for right third-branch trigeminal neuralgia. He had stopped taking the medication after the neuralgia resolved. When the neuralgia recurred, he resumed medication, and about 1 month later he developed fever, fatigue, cervical lymphadenopathy, generalized skin flushing, facial edema and perioral vesicles, and was admitted to Ichikawa General Hospital, Tokyo Dental College. Oral findings showed reddening and erosion of the buccal mucosa. Routine laboratory examination revealed leukocytosis and hepatic dysfunction. Human herpesvirus 6 antibody titer remarkably increased during development of eruptions. These findings led to a diagnosis of drug-induced hypersensitivity syndrome. Carbamazepine was discontinued, and prednisolone (30 mg/day) was started and tapered based on improvement of symptoms. Because skin symptoms recurred after he was discharged 15 days after admission, the dose of prednisolone was increased and the symptoms finally disappeared. The patient has experienced no further recurrence.

Systemic mastocytosis (SM) is a heterogeneous disease of the bone marrow characterized by abnormal growth, accumulation and activation of clonal mast cells (MCs). We report a case of SM with multi-organ involvement. A 30-year-old man presented with diarrhea, flushing, maculopapular rash with itching and weight loss. The upper and lower gastrointestinal endoscopies showed macroscopic involvement of stomach and duodenum; mucosal samples from stomach, duodenum, colon and distal ileum showed mucosal infiltration by large, spindle-shaped MCs with abnormal surface molecule expression (CD2 and CD25), a picture fully consistent with SM, according to the World Health Organization diagnostic criteria. A computed tomography scan showed diffuse lymphadenopathy, hepatosplenomegaly and diffuse small bowel involvement. Bone marrow aspirate and biopsy were diagnostic for SM; serum tryptase levels were increased (209 ng/mL, normal values < 20 ng/mL). The conclusive diagnosis was smouldering SM. There were no therapeutic indications except for treatment of symptoms. The patient was strictly followed up because of the risk of aggressive evolution.
