Case 1. A 39-yr-old male was presented with anemia. Initial blood examination showed remarkable iron deficiency anemia. Small bowel X-ray and abdominal CT examination revealed a dilated tract at the end of the ileum. Surgical operation was done. The surgical specimen showed side to side anastomosis which was reconstructed at the operation for rt. inguinal herniation 46 days after his birth. The oral side of the tract was remarkably dilated. Case 2. A 50-yr-old male was presented with dizziness. He had anemia and clubbed fingers. A small bowel X-ray examination was done and it showed side to side anastomosis in the middle of the small intestine. Surgical operation was performed. The surgical specimen showed side to side anastomosis about 2 m 20 cm from the Treitz' ligament, which was reconstructed during the operation for ileus when he was 10 years old. The blind portion was remarkably dilated. In both case, the anemia was improved after the operation.

Head injuries have been shown to account for between 4 and 22% of soccer injuries. Clinical and neuropsychological investigations of patients with minor head trauma have revealed organic brain damage. 69 active football (soccer) players and 37 former players of the Norwegian national team were included in a neurological and electroencephalographic (EEG) study to investigate the incidence of head injuries mainly caused by heading the ball. 3% of the active and 30% of the former players complained of permanent problems such as headache, dizziness, irritability, impaired memory and neck pain. 35% of the active and 32% of former players had from slightly abnormal to abnormal EEG compared with 13 and 11% of matched controls, respectively. There were fewer definitely abnormal EEG changes among typical 'headers' (10%) than among 'nonheaders' (27%). The former players were also subjected to cerebral computed tomography (CT), a neuropsychological examination and a radiological examination of the cervical spine. One-third of the players were found to have central cerebral atrophy and 81% to have from mild to severe (mostly mild to moderate) neuropsychological impairment. The radiological examination of the cervical spine revealed a significantly higher incidence and degree of degenerative changes than in a matched control group.

Aspartame is a low-calorie food sweetener recently approved by the FDA for general human consumption. One of us (AJG) treated a patient whose symptoms of episodic vertigo and continuous unsteadiness resolved upon ceasing aspartame intake. A literature review revealed that although dizziness has been associated with aspartame intake, no systematic study of the problem exists. As an initial attempt to ascertain the prevalence of aspartame-related dizziness in an otolaryngologic clinic, we elected to study prospectively all patients entering with the complaint of vertigo by means of a standardized questionnaire. Those patients determined to consume aspartame were further studied in a nonblinded manner to see if aspartame intake could be correlated to symptomatology. A cross-over limb was also attempted, but no patient would participate. This presentation details the case history of the propositus patient and the preliminary results of the currently ongoing prospective study.

Researchers analyzed data on 1572 18-44 year old women attending 1 of 10 institutions in 7 provinces and cities in China to examine the side effects of oral administration of 600 mg RU-486 followed by 1 mg of a prostaglandin (PG05) vaginal suppository and this combination's efficacy in terminating early pregnancy. Incomplete abortion occurred in 4.8% of the women; continuation of pregnancy, in 3.9%. 91.2% of the women experienced a complete abortion, which took an average of 2.4 days. Just 3.3% of the women experienced expulsion before insertion of the PG05 vaginal suppository. 81% expelled the fetal sac within 6 hours after PG05 insertion. 88% of women with complete abortion had bleeding on day 2 or 3 and bled on average 11.7 days. 24.5% experienced bleeding for more than 14 days; the bleeding was heavy for 47.4% of them. 1 women bled so profusely she required 2 blood transfusions. The leading side effects were nausea and vomiting (22.3%), abdominal pain (10.2%), headache and dizziness (4.1%), diarrhea (2.8%), and thirst (1.2%). 79.5-96.2% of subjects considered these side effects to be mild or moderate. The side effects persisted for 17-36 hours. None of the women experienced any serious complications that sometimes occur with intramuscularly injected prostaglandins. 92% of the women who experienced complete abortion considered this method to be at least good. The corresponding figure for the incomplete abortion and failed groups was 26.3% and 41.9%, respectively. The researchers concluded that this combination was effective and safe for termination of early pregnancy. They suggested that health workers counsel the women before treatment to increase tolerance of the mild to moderate side effects.

The authors describe two recently observed cases of silent angina with ST segment elevation. The patients, both 80-years old, were submitted to 24-hour Holter examination to account for recurrent episodes of dizziness. The examination revealed silent angina with ST elevation concentrated mainly in the late evening and morning hours, accompanied by accelerated heart rate. Treatment with low diltiazem doses was completely successful.

For phenomenological elucidation of panic attacks, 26 patients with panic attacks were requested to name the panic symptoms in order of their occurrence and specify the patterns of their abatement. Panic symptoms were found to be classifiable into three categories: early symptoms consisting of dizziness or faintness, palpitations, and sweating; intermediate symptoms dyspnea, nausea or abdominal distress, flush or chills, chest pain or discomfort, shaking, and choking; late symptoms paresthesias, fear of dying, and fear of going crazy. Panic symptoms disappeared in 61.6% irrespective of the sequence of their occurrence. Twenty-one patients were interviewed about the experience of nocturnal panic attacks, and 23.8% experienced them. These findings suggest that fear is caused by sudden physical abnormality triggered by some biological factors.

The authors studied the sensitivity and specificity of several epidural test doses as markers of intravascular injection in laboring patients in a prospective double-blind, randomized study. Fifty-nine parturients were assigned randomly to receive an intravenous injection of either normal saline solution (3 mL, NS group) or 1.5% lidocaine with epinephrine 1:200,000 (1 mL, EPI-5 group; 2 mL, EPI-10 group; or 3 mL, EPI-15 group). The EPI-5 and EPI-10 doses were diluted to 3 mL volume with normal saline solution. All injections were given during uterine diastole. Maternal heart rate was monitored with a pulse oximeter. An observer who was unaware of the study treatment recorded the baseline and the peak maternal heart rate within the first minute after the injection and questioned the patient about tinnitus, dizziness, metallic taste, and palpitations. He then recorded his opinion as to whether the patient had received the saline or the test solution. Analysis of the maternal heart rate showed an average increase (baseline-to-peak criterion) of 8 +/- 10 beats/min (mean +/- SD) in the NS group. In the other groups, the increase was 21 +/- 8 (EPI-5 group), 31.5 +/- 13 (EPI-10 group), and 29 +/- 9 beats/min (EPI-15 group). A baseline-to-peak criterion of greater than 10 beats/min identified all intravascular injections in the EPI-15 (by design) and EPI-10 groups (15 of 15 and 14 of 14, respectively) with a sensitivity of 100%. Specificity was 73% (11 of 15 true negatives).(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical, ECG, and electrophysiologic data from 47 patients who had episodes of sustained or nonsustained monomorphic VT with no evidence of structural heart disease were reviewed. According to the QRS configuration during tachycardia, four groups were distinguished. Nine patients had a right bundle branch block configuration and superior frontal plane QRS axis (group 1). Nine patients had a right bundle branch block configuration but an intermediate or right QRS axis (group 2). Group 3 consisted of five patients with a left bundle branch block configuration and a left axis deviation, and in group 4 there were 24 patients who had a left bundle branch block configuration with an intermediate or right frontal axis. Patients in group 1 had dizziness during tachycardia less frequently, but they needed cardioversion to terminate their arrhythmias more often. They experienced tachycardia during exercise less often, and tachycardia was not initiated during exercise testing. They had fewer ventricular premature beats according to the Holter recording. During the electrophysiologic study, VT was induced and terminated by pacing more often in this group. Patients with idiopathic VT with a right bundle branch block configuration and a superior axis seem to be a unique group of patients with idiopathic VT, and reentry seems to be the most likely arrhythmia mechanism in this group. The other ECG configurations share the same clinical and electrophysiologic characteristics, which suggest that the underlying arrhythmia mechanism is the same.

A 69-year-old woman was referred for asthenia and dizziness when walking in the last two months. No clinical abnormalities were found, and sinus rhythm was present when lying down. On orthostatism and walking, advanced AV block developed. Atropine and isoproterenol ameliorated the AV conduction abnormality, suggesting a nodal block. The patient remained asymptomatic after pacemaker implantation.

Implantation of a single-chamber pacemaker was planned in an 83-year-old woman with sick-sinus syndrome causing dizziness, bradycardia and tachycardia. After puncture of the right subclavian vein it proved impossible to advance a guide-wire into the superior vena cava, under fluoroscopy the wire always being seen to coil in the left subclavian vein and hence passing into a caudally directed vein. This vessel proved to be a persistent left superior vena cava (PLSVC) which connected to a markedly dilated coronary sinus (2 cm diameter) opening into the right atrium. An 85-cm electrode was then passed via the PLSVC and right atrium into the right ventricle without difficulty and was anchored in its apex. Echocardiography failed to reveal any further anomaly. Three-dimensional computed tomographic reconstruction established atresia or agenesis of the (right) superior vena cava. Normal pacemaker function freed the patient of all symptoms postoperatively.
