    Polycythemia is literally translated as "many cells in the blood". Only erythrocytosis (an alternative term for these disorders) produces polycythemia since leukocytes and platelets are present in blood in far smaller proportions. Polycythemia may be due to increased proliferation or decreased apoptosis of erythroid progenitors, or to delayed erythroid differentiation with an increased number of progenitor cell divisions. Prolonged red cell survival, another theoretical cause of polycythemia, has not yet been described and with intact regulatory mechanisms is unlikely to occur. Primary polycythemias result from abnormalities expressed in hematopoietic progenitors. In contrast, circulating factors cause secondary polycythemia (1). There are acquired and congenital causes of both primary and secondary polycythemia (1).

    Objective Balloon-occluded retrograde transvenous obliteration (B-RTO) has recently been introduced as a new interventional modality to prevent fatal bleeding from solitary gastric varices. A large portal-systemic shunt including gastric varices also causes severe encephalopathy in some cirrhotic patients. In this study, we evaluated the effect of B-RTO as a candidate therapeutic method to treat chronic recurrent hepatic encephalopathy due mainly to a portal-systemic shunt.
    Patients and Methods Since July 1995, we experienced 43 cirrhotic patients with chronic reccurent hepatic encephalopathy. Among them, six patients had anigographically proven large (>1 cm in diameter) portal-systemic shunt, and received B-RTO. B-RTO was carried out only once using 5% ethanolamine oleate with iopamidole to obliterate the portal-systemic shunt for 30 minutes. The median observation period after B-RTO was 29 months (range 23-46 months).
    Results In all 6 patients, encephalopathy had disappeared after B-RTO, and the patients were free of encephalopathy during the following 6 months. B-RTO significantly reduced blood ammonia levels at one month, 3 months, and 6 months later, without affecting serum aspartate aminotransferase activity, total bilirubin and albumin concentrations, and plasma prothrombin time. Encephalopathy relapsed in 4 patients between 6 and 30 months. Additional B-RTO was required and effective in 2 of them.
    Conclusion B-RTO is an effective treatment for chronic recurrent hepatic encephalopathy with an angiographically proven portal-systemic shunt.

    Objective To clarify the incidence of concomitant esophageal cancers in patients with head and neck cancer (HNC), and to investigate which risk factors are responsible for this association.
    Patients and Methods From 1994 to 2000, 134 patients with HNC underwent upper gastrointestinal endoscopy using the 0.8% Lugol stain method to detect esophageal cancer. A case-control study was designed to compare HNC patients with and without esophageal cancer. Logistic-regression analysis was used to obtain odds ratios of risk factors.
    Results Out of 134 patients with HNC, Lugol unstained area was detected in 42 patients. Biopsy specimens revealed squamous cell carcinoma in 17 (12.7%), dysplasia in 9 patients (6.6%), and normal in the others. Gastric carcinoma was also detected in 7 patients (5.2%). The estimated depth of cancer invasion was mucosa in 9 patients, submucosa in 5 patients, and proper muscle or deeper in 3 patients. In the results of statistical analysis, high alcohol consumption of more than 75 g per day increased the risk of esophageal cancer (odds ratio: 20.2, p<0.01). Intake of hard liquor showed a high odds ratio (whisky: 28.7, p<0.05, shochu: 12.7, p<0.05). The amount of cigarette smoking was not related to this association.
    Conclusion High incidence of esophageal cancer was found in the patients with HNC. A high alcohol consumption level, and in particular hard liquor, participated in the development of esophageal cancer in the patients with HNC. But cigarette smoking was not related to this association.

    Objective The present study was undertaken to clarify the clinical course and prognosis of adult patients with primary IgA nephropathy (IgAN), especially with mild proteinuria or mild histological alternations.
    Patients and Methods A population of 735 IgAN patients whom we were able to observe for more than two years was examined.
    Results A total of 115 patients (15.6%) was on dialysis during the observation period. The overall 5-year renal survival rate was 92.0%. On the other hand, 166 patients (22.6%) were in clinical remission. A group with mild proteinuria included 197 patients (26.8%). Forty-seven patients of this group showed minor glomerular abnormalities, whereas 12 patients with mild proteinuria showed severe mesangial involvement. Three patients with mild proteinuria were on dialysis during the observation period, whose proteinuria was increased during the clinical course. A group with minor glomerular abnormalities included 82 patients (11.2%). Forty-seven patients of this group showed mild proteinuria, of whom 12 patients showed moderate proteinuria. However, three patients with minor glomerular abnormalities who were not on dialysis showed loss of renal function.
    Conclusion These results indicated the heterogeneity of the course and prognosis in IgAN. Even if a patient's initial clinical or histological findings are comparatively mild, strict follow-up management is needed.

    Objective To evaluate the clinical features, etiology, and outcome of patients over 65 years old hospitalized for community-acquired pneumonia.
    Patients Eighty-four patients (50 males, 34 females) hospitalized for community-acquired pneumonia in Kawasaki Medical School Kawasaki Hospital between April 1998 and March 2000.
    Results Most of the patients had respiratory symptoms or signs, but over one-third also had atypical symptoms of pneumonia such as dyspnea, consciousness disturbance, and gastrointestinal symptoms. The causative microorganisms were identified in 48% of these patients. Streptococcus pneumoniae (13%), respiratory viruses (13%), Haemophilus influenzae (8%) and Mycobacterium tuberculosis (8%) were frequently identified, but Mycoplasma pneumoniae was less frequently noted in the elderly. Double infection was recognized in 19% and a combination of some virus and bacteria in 13%. Treatment consisted of the administration of second or third generation cephalosporin antibiotics intravenously, because antibiotics had already been preadministered in 39%. The prognosis was poor (mortality rate 9%) for the elderly with community-acquired pneumonia despite mechanical ventilation in 8%.
    Conclusions Although the range of microorganisms causing community-acquired pneumonia differed slightly from that in previous reports; namely, lower frequency of Chlamydia pneumoniae and Legionella pneumophila, it is suggested that the initial antibiotic treatment should always cover S. pneumoniae and H. influenzae. In addition, since a prevalence of virus infections related to the increase in community-acquired pneumonia in the elderly was found in this study, the routine use of influenza vaccine and pneumococcal vaccines in the elderly is recommended to reduce the high mortality rate.

    We treated a 67-year-old Japanese woman with membranoproliferative glomerulonephritis (MPGN) and chronic active hepatitis associated with hepatitis C virus (HCV) infection. Treatment commenced with a daily dose of 6 MUIFN a-2b for 2 weeks, which was changed to three times weekly thereafter. After 2 weeks, HCV RNA in the serum was undetectable and there was a concomitant reduction in proteinuria. Treatment with IFN a-2b was discontinued because of severe headache and fever. Five weeks after the discontinuation of IFN oc-2b, the patient experienced the sudden onset of visual loss due to retinal hemorrhage. Subsequently, proteinuria and renal function progressively deteriorated though HCV RNA was undetectable. This case exemplifies the need for careful monitoring of renal function and retinal lesions not only in patients receiving IFN but also in those following the discontinuation of IFN treatment.

    We report two identical male twins who suffered from superior mesenteric artery (SMA) syndrome. A 28-yearold man was admitted for investigation of postprandial nausea and vomiting. Upper gastrointestinal examination revealed a dilated proximal duodenum with an abrupt vertical cutoff of barium flow in the third portion of the duodenum, establishing the diagnosis of SMA syndrome. One year later, his twin brother also presented similar symptoms and was radiologically diagnosed as SMA syndrome. The twin brothers did not respond adequately to conservative therapy and underwent duodenojejunostomy. This is the first report of SMA syndrome in identical twins.

    A 27-year-old woman was admitted for further examination of thrombocytopenia. Symptoms were absent, but physical examination demonstrated hepatosplenomegaly without neurological abnormalities. Bone marrow examination revealed many Gaucher cells, and glucocerebrosidase activity from cultured skin fibroblasts was markedly reduced. A 1448C (L444P) mutation was detected on one allele of the glucocerebrosidase gene. Because magnetic resonance imaging (MRI) of the femora indicated severe infiltration of Gaucher cells into bone marrow, enzyme replacement therapy was initiated despite the absence of skeletal symptoms. Hematologic abnormalities, visceral and bone involvement have been improving. In cases of thrombocytopenia or hepatosplenomegaly, Gaucher's disease should be suspected.

    A 66-year-old man with hemoptysis, chest pain, fever, and hoarseness was admitted to our department. A rightsided aortic arch and three aneurysms in the proximal arch, distal arch, and descending aorta were confirmed by aortography and surgery. Fistula formations were discovered between the proximal arch aneurysm and the right upper lobe (aortobronchopulmonary fistula: ABF), and between the descending aorta and the esophagus (aortoesophageal fistula: AEF). Concomitant ABF and AEF are very rare. Aortopulmonary and/or aortoesophageal fistula complicated by a right-sided aortic arch have not been previously reported.

    A 31-year-old man was admitted to our hospital for further evaluation of heart failure symptoms. Crow-Fukase syndrome was diagnosed on the basis of findings of polyneuropathy, hepatomegaly, monoclonal hypergammaglobulinemia, and hypertrichosis. Dipyridamole-stress thallium-201 perfusion imaging, contrast left ventriculography, and coronary angiography revealed a markedly dilated and dysfunctioning left ventricle, extensive reversible ischemia with fixed defect, and multiple coronary lesions. Histopathology of myocardial biopsy specimens demonstrated ischemia-induced myocardial necrosis. These findings suggested that ischemic cardiomyopathy, probably due to inflammatory reactions of coronary arteries in Crow-Fukase syndrome, was responsible for the heart failure symptoms and left ventricular dysfunction in this patient.

    Monomorphic ventricular tachycardia (VT) developed in two patients with cardiac sarcoidosis. Before treatment with prednisolone, technetium or gallium scintigram revealed abnormal accumulation in the heart and bilateral hilar lymph nodes, but programmed electrical stimulation failed to induce VT in either case. Prednisolone was administered and the abnormal accumulation of the scintigra ms disappeared. However, VT became reproducibly inducible, and in one of the patients, transient entrainment was demonstrated in clinical VT morphology. Defibrillators were implanted in both patients. Some VTs associated with cardiac sarcoidosis are due to reentry, and inducibility of VT is not associated with the activity of cardiac sarcoidosis. Even though steroid therapy suppresses the activity of cardiac sarcoidosis, defibrillator implantation is necessary to prevent a possible arrhythmic event during the follow-up.

    We observed two patients with diabetes who were suffering from nausea, vomiting and epigastralgia after meals. These symptoms subsided when lying on their left side. Since the 2 patients had autonomic neuropathy, at first, the symptoms seemed to be attributable to diabetic gastroparesis. However, they were diagnosed as having superior mesenteric artery syndrome by hypotonic duodenography. These finding suggest that in diabetic patients who have a history of excessive weight loss superior mesenteric artery syndrome should be ruled out even though they have autonomic neuropathy.

    A case of 46, XY pure gonadal dysgenesis with very tall stature was investigated. The 24-year-old, phenotypically female patient consulted our clinic because of linear growth persisting into adulthood. The patient was found to have no mutation or deletion of a sex-determining region of the Y chromosome, and also was found to have Graves' disease. Growth was arrested with height remaining at 187 cm after normalization of the thyroid function by treatment with an antithyroid agent, although follow-up to monitor growth was limited to 3 months. In some cases of gonadal dysgenesis, then, Graves' disease may contribute to an abnormally tall stature.

    We describe the first reported case of painless thyroiditis induced by an abrupt cessation of betamethasone. A 53-year-old woman experienced transient thyrotoxicosis after the abrupt cessation of celestamine, a mixture of betamethasone and chlorpheniramine. Since neither TSH receptornor thyroid stimulating-antibodies were negative, and thyroid scintigram did not show the thyroid gland, she was diagnosed as having painless thyroiditis. Fourteen months after the onset of thyrotoxicosis, serum TSH was detectable without hypothyroidism. We speculate that reduction in betamethasone may be one of the triggers of painless thyroiditis.

    We report a case in which pituitary apoplexy developed shortly after an intravenous (i.v.) injection of luteinizing hormone-releasing hormone (LH-RH). A 56-year-old man with prolactin-producing pituitary tumor complained of severe headache, visual field loss and facial nerve palsy shortly after LH-RH test. Magnetic resonance image (MRI) revealed a hemorrhage in the pituitary adenoma. He showed dramatic improvement in his symptoms after decompression surgery. These findings suggest a causal relationship between the i.v. injection of LH-RH and pituitary apoplexy. Possible pituitary apoplexy should be kept in mind during pituitary testing.

    We report a 19-year-old woman who was diagnosed as polycystic ovary. Hypothyroidism with a markedly elevated TSH level and an enlarged pituitary gland on MRI were noted. The 123I uptake was decreased to 6.5%. After treatment with thyroid hormone, regression of the enlarged pituitary and the ovarian cysts was observed. In the present case, hypothyroidism was considered to have caused a reversible enlargement of the pituitary gland and concomitant polycystic ovary. We concluded that the polycystic ovary might have resulted from the effects of an excessive amount of TSH on immature ovaries.

    Resistance to thyroid hormone (RTH) is a genetic disorder caused by mutations in the thyroid hormone receptor (TR) β gene. The mutations are clustered in two regions: exon 9 and exon 10. To date, only one patient with an exon 9 mutation has been reported in Japan. We herein report three patients from two Japanese families with RTH and mutations in exon 9. A 52-year-old woman and her 18-yearold daughter, both with inappropriate secretion of TSH (SITSH) were diagnosed simultaneously with generalized RTH. Molecular analysis revealed a G345D mutation. An 11-year-old girl with SITSH, whose only manifestation was a goiter, had an R338W mutation, which is frequently associated with pituitary RTH. Thus, RTH with mutations in exon 9 of the TR β gene is not so rare in Japan.

    A 78-year-old woman was hospitalized for congestive heart failure and repeated hypoglycemic attacks. The laboratory data showed a serum insulin level within the normal range and an increased level of serum insulin-like growth factor (IGF) II. Abdominal ultrasonogram and computed tomography scan reveaeled a huge mass lying above the left kidney. She was diagnosed as having an adrenocortical carcinoma. After the removal of the tumor, the plasma glucose level and the serum level of IGF-II were normalized. The tumor cells stained positively for IGF-II immunohistochemically. These findings suggested that the hypoglycemia was due to IGF-II produced by the adrenocortical carcinoma.

    A 53-year-old Japanese man with recurrent interstitial pneumonia was referred to us. The patient had taken a traditional herb medicine, otsu-ji-to, before the onset of pneumonia. A provocation test for each herbal ingredient contained in otsu-ji-to revealed that the pneumonitis had been induced by ou-gon (scullcap). Lymphocytosis with the CD8+ T-cell subset predominance was found in the bronchoalveolar lavage fluid and lymphocytic alveolitis was noted in the transbronchial lung biopsy specimen after the provocation test. Ou-gon, or scullcap, should be included in the list of drugs with definite causal association with pneumonitis.

    Sarcoidosis is a systemic granulomatous disease of unknown etiology. Sarcoidosis affects multiple organs; the lungs, lymphoid system, eyes and skin are usually involved. Commonly, any organ system may be affected. Sarcoid involvement in the nervous system, locomotor system, lacrimal and salivary glands, heart, kidney and liver has been recognized in patients with Sarcoidosis. However, sarcoid involvement of the breast parenchyma has been extremely rare in patients with Sarcoidosis. Herein, we report a patient with a sarcoid breast mass who had bilateral hilar lymphadenopathy and lymphocytosis in bronchoalveolar lavage analysis.

Thyroid cancer, and multiple small nodules in both lungs were noted. He underwent total thyroidectomy followed by radiotherapy with 131I. However, 131I scintigraphy showed poor uptake of radionuclide in the nodules, and the size of the nodules remained unchanged. The diagnostic thoracoscopic biopsy showed two types of nodules, some were positive for thyroglobulin and cytokeratin, and others were reactive for factor VIII. The former nodules were diagnosed as pulmonary metastases of thyroid cancer, and the latter EH.

    A 72-year-old man was admitted to our hospital with fever and cough. He had been on disopyramide treatment for nine days to control cardiac arrhythmia. On admission, chest X-ray examination revealed reticulonodular opacities in both lungs, and impending respiratory failure was evident. A differential cell count of the bronchoalveolar lavage fluid (BALF) showed a marked increase of lymphocytes. A lymphocyte stimulation test (LST) for disopyramide using BALF was positive, although the test using peripheral blood was negative. This case suggests that LST using BALF is useful for the diagnosis of drug-induced pneumonitis.

    We describe a case of vinorelbine tartrate (VNR) associated acute respiratory failure. A 65-year-old man with nonsmall cell lung cancer developed acute respiratory failure 50 minutes after his first infusion with YNR in combination with mitomycin-C. The patient was treated with furosemide, dopamine and high-dose methylprednisolone, and recovered with no discernible sequelae. Although clinical trials have shown that respiratory symptoms associated with VNR treatment have only rarely been observed and the putative mechanism remains to be elucidated, patients receiving YNR should be monitored carefully, particularly in the first few hours after intravenous administration.

    A rare form of sparganosis with eosinophilic pleural effusion is reported. A 62-year-old man was admitted to our hospital with left pleural effusion, and diagnosed immunologically as having sparganosis. Eosinophilia was seen in both peripheral blood and pleural effusion. The level of interleukin (IL)-5 was elevated in the pleural effusion, but not in peripheral blood. The patient was treated successfully with three consecutive doses of praziquantel (75 mg/kg/day). After the treatment, the antibody titer in serum decreased and the eosinophil number in the peripheral blood returned to the normal level. Thus, sparganosis should be included in the differential diagnosis for eosinophilic pleuritis. The immunoserological screening test using multiple-dot ELISA is helpful to identify the causative pathogen.

    A 27-year-old man with a primary pulmonary lymphoma of large B-cell type is described. Symptoms involved both the upper and lower respiratory tract. A chest roentgenogram showed a dense mass with cavitation. Transbronchial biopsy specimens revealed no atypical cells, rather they demonstrated granulomatous infiltration and vasculitis consistent with but not conclusively diagnostic of Wegener's granulomatosis. The pulmonary mass became smaller after sulfamethoxazole-trimethoprim therapy. These features suggested Wegener's granulomatosis. However, an open biopsy specimen was diagnostic for diffuse lymphoma of large B-cell type. High-grade pulmonary lymphoma should be considered in the differential diagnosis of patients with clinical and pathologic features suggesting Wegener's granulomatosis.

    A 62-year-old woman treated with pranlukast for 2 months developed interstitial pneumonitis with a high fever. A lymphocyte stimulation test was reactive to pranlukast. Her clinical symptoms improved with discontinuation of pranlukast and administration of systemic corticosteroid. To our knowledge, this is the first reported case of drug-induced lung disease involving a leukotriene. The steps that can be taken to promptly reach a diagnosis and to successfully treat this life-threatening condition are described.

    Two cases of acquired immunodeficiency syndrome with myelodysplasia are presented. Case 1 was admitted because of Pneumocystis carinii pneumonia. Mild anemia, thrombocytopenia and hypersegmented neutrophils were observed. After the administration of trimethoprim-sulfamethoxazole and antiretroviral therapy, pancytopenia progressed. Bone marrow (BM) showed dysplastic hematopoiesis, suggesting human immunodeficiency virus-myelopathy. Case 2 was hospitalized due to progressive multifocal leukoencephalopathy. BM specimen obtained for thrombocytopenia showed myelodysplasia similar to myelodysplastic syndrome, suggesting that HIV may have an influence on hematopoietic progenitor cells.

    A 65-year-old man, who is a Jehovah's Witness, was admitted to our hospital due to progressive anemia following a four-year history of biclonal gammopathy of no clinical significance. He was diagnosed with pure red cell aplasia (PRCA) associated with plasma cell dyscrasia. Despite a markedly decreased red blood cell count (hematocrit 5.6%), the patient refused transfusion. He was intravenously administered bolus methylprednisolone. Reticulocytosis and recovery from anemia were observed on day 7 after the start of therapy. Secondary PRCA following plasma cell dyscrasia is a rare disorder; the treatments for this rare condition are discussed.

    A 74-year-old man developed fever, somnolence, hyponatremia, and life-threatening sinus bradycardia for three weeks. He showed a slight elevation of lymphocyte count and protein level in the cerebrospinal fluid. A brain CT scan revealed a diffuse low density area around the hypothalamus which was identified as a high intensity signal by flair MR imaging. Marked sinus bradycardia developed with no abnormality in the echocardiograph or cardiac enzymes. Over the next 6 weeks he became alert and normal sinus rhythm resumed. The results of endocrine tests were compatible with hypothalamic insufficiency with partial hypopituitarism and the syndrome of inappropriate secretion of ADH.

    A 72-year-old man presented with paroxysmal and transient involuntary movements, or "limb shaking". The attacks occurred alternately from one side of the body to the other and ceased spontaneously. Surface EMG study showed synchronous grouping discharges in multiple limb muscles, being compatible with hemiballism-hemichorea. Cerebral angiography demonstrated marked stenosis of the bilateral internal carotid arteries. Bilateral carotid endarterectomy led to complete disappearance of the involuntary movements. Alternating paroxysmal hemiballismhemichorea might be a transient ischemic attack, and alternating striatal dysfunction induced by cerebral hemodynamic or microembolic ischemia probably plays a central role in the occurrence of such involuntary movements.

    An 18-year-old woman presented with coma, hemicomvulsions, and transient periodic lateralized epileptiform discharges (PLEDs). Serological tests were positive for influenza B, and cerebrospinal fluid PCR for herpes simplex virus DNA was negative. Magnetic resonance imaging later showed abnormal signal intensity in the temporal lobe ipsilateral to the PLEDs. Influenza-associated encephalopathy may cause hemiconvulsions and PLEDs, and can mimic herpes simplex encephalitis.

    Muscle symptoms are known as adverse effects of HMG-CoA reductase inhibitors but their incidence is reported to be low. We treated a case of shoulder stiffness related to such a drug, which prompted us to preliminarily survey its incidence. We found that nearly one-tenth of women (6/66) taking such drugs reported drug-related shoulder stiffness. Shoulder stiffness is a very common symptom, while druginduced shoulder stiffness is generally unknown. Many cases involving such an adverse effect may thus be overlooked. We present 2 typical cases here.

    This is the first case report of Hodgkin's disease (HD) which showed both remission and exacerbation of neurological signs before a confirmed diagnosis of HD. The episodes occurred three times and multiple lesions were involved. Immunoabsorption plasmapheresis and double filtration plasmapheresis were effective for the first episode, whereas, corticosteroids partly improved the second and third episodes. Fever and lymph node swelling were apparent afterward and she was diagnosed as having HD from a supraclavicular lymph node biopsy. The remaining neurologic deficits responded to chemotherapy and radiotherapy. The neurological symptoms were considered as a paraneoplastic syndrome of HD.

    We report a rare association of amyotrophic lateral sclerosis (ALS) with incidental pulmonary and muscle sarcoidosis. A 63-year-old woman presented with slowly progressive weakness and atrophy of the extremities starting from the left leg. The biopsy of a small mass in the left gastrocnemius revealed a typical sarcoid nodule. She was treated with corticosteroid for possible sarcoid neuromyopathy. In spite of the treatment, her clinical course was relentlessly progressive and she died of bulbar palsy. Autopsy revealed a loss of motor neurons in the anterior horn, vacuolar degeneration of the lateral funiculus, and noncaseating granulomas in paratracheal lymph nodes and lungs. No granulomatous lesion or cellular infiltration was found in the spinal cord.

    We describe a 72-year-old woman with hypertension who developed acute neurogenic pulmonary edema and giant negative T waves on electrocardiography (ECG) due to subarachnoid hemorrhage. The patient was alert and complained of precordial chest discomfort, dyspnea and shoulder stiffness. Echocardiography demonstrated normal left ventricle contraction with hypertrophy. Computed tomography (CT) and subsequent cerebral angiography revealed subarachnoid hemorrhage and saccular aneurysm at the anterior communicating artery. It is important to consider the possibility of subarachnoid hemorrhage when a patient shows pulmonary edema and ECG abnormalities even without typical clinical signs of subarachnoid hemorrhage.

    We present here a case of Sjögren's syndrome (SjS) with osteomalacia based on renal tubular acidosis type 1 (RTA1). A 53-year-old woman, diagnosed as having rheumatoid arthritis (RA) at the age of 33, was admitted to our hospital because of sicca complex, fatigability and worsening general aching. The activity of RA had been low, but it was complicated by SjS, RTA-1 and remarkable osteomalacia. Acidosis was corrected by alkali supplement therapy. By treatment with a regimen consisting of alfacalcidol, calcium L-aspartate, elcatonin and ipriflavone, her bone mineral density (BMD) was remarkably improved within months and the generalized aching gradually diminished.

    Eight cases of allergy-like food poisoning resulting from the ingestion of yellowfin tuna, which had been kept in stock for 10 days prior to being cooked, are described. The main symptoms were headaches, facial flushing and palpitation. Samples of the ingested fish were analyzed for histamine content, and a high level of histamine was confirmed (310 mg/100 g of fish). Corticosteroids were given to 3 patients who exhibited dyspnea or persistent symptoms, while the remaining patients improved without medication. In situations where allergy-like clinical features are present after the ingestion of food, the possibility of allergy-like food poisoning should be recognized and included in a differential diagnosis.

    We report a rare case of herpes simplex virus (HSV) bronchopneumonia in an otherwise healthy middle-aged individual. Bronchoscopy indicated scattered white-coated lesions in the bronchial mucosa. The diagnosis was established following immunohistopathological staining for HSV of specimens obtained by bronchial biopsy. This case suggests that HSV could be a pathological agent of not only oral and genital mucosal lesions but also lower respiratory tract infection.
