Helical CT scanning of laryngeal deviation.

Objective: To evaluate helical computed tomography (CT) scanning in patients with laryngeal deviation.

Materials And Methods: Five patients with laryngeal deviation and three control subjects underwent helical CT. The laryngeal deviation was idiopathic in one patient and acquired in four.

Accuracy of detection of colorectal neoplasia using an immunochemical occult blood test in symptomatic referred patients: comparison of retrospective and prospective studies.

Objective: In this study the sensitivity and specificity of immunochemical tests for colorectal neoplasia were evaluated in retrospective and prospective studies.

Methods: Four types of fecal blood tests--a chemical test (Hemoccult II) and three different immunochemical tests including a test which detects hemoglobin and transferrin- were performed in the retrospective study. In the prospective study the test for hemoglobin and transferrin was used for all patients that underwent total colonoscopy.

Immunocytochemical distribution of the c-H-ras protein in nasal polyps: localization to the terminal bars.

Objective: This study was performed to investigate the role of proto-oncogene products, c-H-ras and c-erbB-2, in the pathophysiology of nasal polyps.

Methods: An immunocytochemical investigation of the expression of proto-oncogene products of c-H-ras and c-erbB-2 was performed on 16 nasal polyps and 15 nasal mucosa specimens.

Results: The c-H-ras protein was found to be localized to the terminal bars of apical cells of the epithelium in 11 of 16 nasal polyps and in seven of 15 nasal mucosa.

Inflammatory cells in nasal mucosa and nasal polyps.

Objective: Since some controversy exists concerning the frequency of inflammatory cells in nasal polyps, we have compared the frequency of tissue inflammatory cells (lymphocytes, neutrophils, eosinophils and plasma cells) including 11 kinds of lymphocyte subsets in the same specimens of nasal mucosa and nasal polyps.

Methods: Histopathological observations and flow cytometric analyses were performed on eight mucosal specimens of the inferior turbinates of patients with nasal polyps and on 13 polyp specimens.

Results: Nasal polyps contained significantly more eosinophils, neutrophils and plasma cells than nasal mucosa, and EG2+ cells (activated eosinophils) were significantly more frequent in nasal polyps than in nasal mucosa.

A case of multiple symmetrical lipomatosis (Madelung's disease).

Multiple symmetrical lipomatosis (Madelung's disease) is a rare disease with multiple symmetrical unencapsulated fatty accumulation diffusely involving the neck, the shoulders and the upper extremities (Kohan et al. Otolaryngol. Head Neck Surg.

Arterial blood gas abnormalities in patients with dizziness.

Arterial blood gases were analyzed in 121 patients with dizziness. Sixty-one showed arterial blood gas abnormalities in the dizziness period. An increase in bicarbonate was seen in 57, increases in both bicarbonate and arterial carbon dioxide pressure in 8, and a low arterial oxygen pressure in 22 patients.

On the frequency of thyroid diseases in outpatients in an ENT clinic.

The prevalence of thyroid diseases was studied in the ENT department of Kobe Teishin Hospital. Between January 1990 and June 1994, 6,348 outpatients (3,004 women and 3,344 men) visited the ENT department with problems of ear, nose, and throat. Among them 114 patients (82 women and 32 men) were revealed to have thyroid diseases (1.

[Allergic bronchopulmonary aspergillosis (allergic bronchopulmonary fungal diseases)].

Allergic bronchopulmonary aspergillosis (ABPA) is an allergic disease caused by viable Aspergillus in a relatively large bronchus and by the type I and type III allergies against the fungus. The clinical findings are characterized by recurrent pyrexial attacks (fever, cough and mucopurulent sputum containing mucous plugs, numerous eosinophils and the fungus), radiological evidence of recurrent collapse and consolidation in different areas of the lung, a blood eosinophilia and elevated serum IgE levels. Fungi other than Aspergillus may cause similar allergological diseases.

Effect of 1 alpha (OH)-vitamin D3 on insulin secretion in diabetes mellitus.

Fourteen non-insulin-dependent diabetic subjects were placed on a balanced diet for 2-3 weeks followed by the same balanced diet alone (group I: control, n = 7) or daily administration of 1 alpha (OH)-vitamin D3 (1 alpha (OH)D3) (group II: 2 micrograms/day, n = 7) additionally for the next 3 weeks. A 75 g oral glucose loading test was conducted before and after the experiment and the plasma insulin response was compared along with the metabolic parameters including serum calcium, phosphorus and serum lipids. The following results were obtained.
