Appearance of basophils in the sputum of patients with bronchial asthma

A total of 108 samples of sputum obtained from twenty patients with bronchial asthma were examined for appearance of basophils and eosinophils. Both cell types are present in sputum during an asthmatic attack and disappear at the conclusion of the attack. Their presence correlates with the severity of the disease. It has previously been demonstrated that the blood basophils count falls during attacks of bronchial asthma, and the present study suggests that basophils move from the blood stream into bronchial tissue during the acute phase of an asthmatic attack.     

The Role of the Biopsy in Diagnosis of Early Gastric Cancer

In order to determine the reliability of endoscopic biopsy indiagnosis of early gastric cancer, and to clarify the problemswith biopsies, preoperative endoscopic biopsies from 771 earlygastric cancer cases were reviewed and analyzed clinicopathologicallyin comparison with surgically resected specimens. The 771 cancerswere surgically resected at the National Cancer Center Hospitalduring the period from 1972 to 1982. Definite histological diagnosiswas obtained in 87.4% of the carcinomas at the initial biopsies.Repeated biopsy raised the percentage of correct definite diagnosesto 96.1%. False-negative (including suspicion of cancer) diagnosiswas most frequent in the case of depressed lesions (50 lesions).Half of the false negatives were found to be due to samplingerrors by the endoscopists. The other half of these 50 lesionswere diagnosed as "suspicious of malignancy" because of thehistological difficulty in differentiating early gastric cancerfrom regenerative atypia with intestinal metaplasia, or becausethere was not enough information, or for the other reasons.Most of the 31 false-negative diagnoses at the initial biopsyfrom elevated lesions were reported as adenoma (group III) orsuspicious of carcinoma (group IV), indicating that differentialdiagnosis between well-differentiated adenocarcinoma and adenomais very difficult. The result of the present study suggeststhat repeated biopsy from correct sites and discussion of thelesions between clinicians and pathologists are very important. ^**Present affiliation: Toranomon Hospital, Toranomon 2-2-2,Minato-ku, Tokyo 105, Japan.     

Blast Crisis of Chronic Myelogenous Leukemia with Tumor Formation Characterized by T-cell Features--A Case Report

We report a case of chronic myelogenous leukemia (CML) associatedwith pronounced peripheral lymphadenopathy, with the cells havingthe Philadelphia (Phl) chromosome and T-cell features. A 23-year-oldman who was diagnosed as having CML and treated with busulfanwas admitted to our hospital because of increasing hepatosplenomegalyand pronounced lymphadenopathy. An axillary lymph node biopsydisclosed that the malignant cells formed rosettes with neuraminidase-treatedsheep red blood cells (En) (95.0%) and were positive for Leu1 (91.8%). Of the cytochemical reactions, peroxidase was negativeand periodic acid-Shiff, acid -naphthyl acetate esterase andß-glucuronidase were all positive. The karyotype ofthe bone marrow cells was 46 XY Phl positive (22q–), andthat of the lymph node cells was 51 XY Phl positive +8, +9,+18, +19, +21, 22q–. He was treated with various anti-leukemicagents and irradiation. Despite such treatments, he died ofpneumonia. This is a report of a CML patients with blast crisisand tumor formation characterized by T-cell features.     

Metastatic Tumors of the Stomach Detected by Endoscopy

Thirteen patients with gastric metastasis were examined endoscopicallyand their diseases were diagnosed histologically at the NationalCancer Center Hospital from 1962 to 1980. Their endoscopic findings were analyzed. The metastatic lesionwas solitary in 10 of the 13 cases and multiple (9 lesions)in three. Although 12 of the 13 cases showed elevated lesionsendoscopically, ulcerated hemispherical nodules, which correspondto the "bull's-eye sign" of Pomerantz roentgeno-graphically,were observed in only four cases. In the remaining nine casesthe endoscopic findings were submucosal tumor without centraldepression (2 cases), a cancer-like appearance (6 cases) orextragastric compression (1 case). The majority of these metastatic lesions (9 of the 19; 47.3%)were located along the greater curvature of the stomach. Fromthese results, the elevated lesion of the greater curvaturemight suggest a metastatic tumor regardless of the conventionalcriteria (multiplicity or ulcerated hemispherical nodule) whenthe patient has cancer in other organs.     

Nonulcerative Lesion Detected by Endoscopy as an Early Expression of Gastric Malignancy: --Retrospective Observation of 72 Cases of Gastric Carcinoma--

To evaluate the endoscopic criteria for early malignant findingsof gastric carcinoma more precisely, a retrospective examinationof endoscopic pictures of 72 patients with gastric carcinomawas carried out. The patients had received endoscopic examinationsrepeatedly for years and proceeded finally to surgery on thebasis of a diagnosis of carcinoma by gastric biopsy. The macroscopicas well as microscopic findings of the resected specimens werecompared with the previous endoscopic observations. Ulcerative lesions were predominantly found at the initial endoscopyin patients whose final diagnosis was the lie type of earlygastric cancer or IIc-like advanced cancer. These patients usuallyreceived endoscopic examinations repeatedly and their lesionswere diagnosed as malignant by the adopted criteria of earlygastric cancer 2 to 6 yr after the initial examination. In contrast, nonulcerative lesions were observed more frequentlyat the initial examination in patients with the final diagnosisof the IIa+IIc type of early gastric cancer or Borrmann typeof advanced cancer. In most of those patients endoscopic examinationwas not carried out so frequently, and in some of those whohad been closely followed the malignant findings appeared rathersuddenly with tumorous formation as well as deeper invasionduring less than a few years from the previous examination atwhich the tumor had been considered benign. These data indicate that the nonulcerative lesions which wereconsidered benign could be the early expression of gastric carcinoma.It should be stressed that nonulcerative lesions such as "irregularerythematous change, discoloration, flat granular change" and"simple mucosal depression" observed in some parts of the stomachwould be important site for the detection of early gastric carcinoma,and that these lesions need to be biopsied more frequently.     

Acute childhood leukemia in a patient with hemophilia: First report in Japan

This study reports an unusual case of acute leukemia which was diagnosed as hemophilia A on initial admission for leukemia. A 3 year old boy was admitted to Kagoshima University Hospital with anemia. He was diagnosed as acute lymphoblastic leukemia. At the same time he was revealed to have severe hemophilia A⁻ without any previous episodes of severe bleeding tendency or family history of this disease. The laboratory investigation showed his mother to be a carrier of hemophilia A. Although there are many cases of hemophilia which have developed malignant tumors, most of them were caused by association with human immunodeficiency virus (HIV) infection. Only five cases with coexistence of leukemia and hemophilia without HIV infection have been reported and the present case is the first one in Japan. At this stage, hemophiliacs are not necessarily regarded to be a population at risk for the development of leukemia. Furthermore, no particular subtype of leukemia was characterized among these patients in the literature.     

Resetting of Tachycardia Cycle by Single and Double Ventricular Extrastimuli in Recurrent Sustained Ventricular Tachycardia

In two cases with recurrent sustained ventricular tachycardia (VT) due to re-entry, the response pattern to extrastimuli during the tachycardia was studied. In each case, right ventricular extrastimuli with longer coupling intervals during VT were followed by fully compensatory pauses and with shorter coupling intervals reset the tachycardia cycle. In one case, a plateau was produced by a single extrastimulus, resembling that seen in the response curve of sinus node automaticity as well as ectopic atrial tachycardia. Two successive stimuli produced three definite zones, i.e., fully compensatory, reset producing a plateau, and progressive prolongation zones with shortening of the coupling intervals between the two stimuli, and terminated the tachycardia with further shortening of the coupling intervals. In conclusion, resetting phenomenon was confirmed on two cases with re-entrant VT. This phenomenon cannot be used as a criterion to determine the mechanism responsible for VT.
