Workups by physicians in response to five common complaints in a sample of 104 men and women--52 married couples--were evaluated by chart audit. For the total group of complaints, back pain, headache, dizziness, chest pain, and fatigue, the physicians' workups were significantly more extensive for men than they were for women. These data tend to support the argument that male physicians take medical illness more seriously in men than in women.

Following oral cholecystography in 100 patients, the conventional "fatty meal" was replaced by an intramuscular injection of Ceruletid in a dose of 0.4 microgram/kg body weight. The synthetic decapetide Ceruletid is a substance with a hormone-like effect on the gastro-intestinal tract. It contracts smooth muscle in the gut and stimulates secretion in the stomach and the exocrine pancreas. Compared with other substances producing contraction which are given orally, Ceruletid acts more quickly and more powerfully in producing contraction of the gall bladder muscle. In 86% of positive cholecystograms, this resulted in satisfactory demonstration of the bile duct, 66% better than for oral substances. Many abnormalities, particularly localised adenomyomatosis, can only be diagnosed after good contraction of the gall bladder. Side effects, such as nausea, dizziness and a feeling of heat were transitory. In three patients it led to vomiting. The rapid and certain effect of Ceruletid during oral cholecystography requires reassessment of the role of intravenous cholangiography in diagnosis. Particularly amongst out-patients, with a high proportion of normal gall bladders, it is possible to complete the examination in one stage by demonstrating the bile duct with Ceruletid.

In a patient with complete A-V block suffering from attacks of dizziness an intermittent A-V conduction with a short P-R interval and a delta wave of the conducted ventricular complex were observed. After accelerating the sinus rate by atropine and by exercise, one-to-one conduction was established with QRS complexes of WPW type A configuration. His bundle recordings revealed a complete block within the normal conduction system at the level of the A-V node. A slow junctional rhythm with a normal H-V interval was activating the ventricle. During atrial pacing a one-to-one conduction through an accessory pathway could be documented at cycle lengths between 800 and 380 msec. sandwiched in between zones of complete block at smaller or longer cycle lengths. During ventricular stimulation no retrograde V-A conduction could be observed. The findings support the thesis of at least two functionally different A-V pathways in patients with pre-excitation syndrome.

This paper describes a nearly 60-year old patient with unilateral hearing loss, developed in one year, and complaints of tinnitus and dizziness. Additional findings were unilateral peripheral facial paresis and a diminished corneal reflex. The cause was found to be a metastasis of an anaplastic carcinoma, localized at the site of the internal acoustic porus.

An outbreak of cadmium intoxication in a jewelry factory provided an opportunity for evaluating the usefulness of diagnostic procedures used to evaluate human cadmium toxicity. Blood cadmium levels in workers exposed to cadmium were higher (.93 micrograms/100ml vs .38 micrograms/100 ml) than in unexposed workers. A dose-response relationship was noted between blood cadmium level and symptom prevalence in four symptoms (dyspnea, chest pain, dysuria, and dizziness). Segmental hair analysis revealed highest cadmium levels (up to 19 micrograms/gm) in segments formed prior to cadmium exposure, suggesting that extrinsic contamination was the primary source of cadmium in the hair. beta2-microglobulin levels were within normal limits. No significant renal or pulmonary dysfunction was noted. Symptoms ceased after a cadmium-containing brazing alloy used in jewelry production was replaced, yet urine cadmium levels remained persistently elevated in four workers. Blood cadmium determinations were found to be useful in evaluating symptoms potentially related to cadmium intoxication.

The authors describe side effects of Dimer X radiculography after premedication. The side effects in a study of hundred patients are divided in early complications (during the examination : dizziness, radicular pains and collapse) and in late complications (noted during the first day following the examination : headache, meningismus, myocloni, epileptic seizure, cauda syndrome, increase of radicular pains). After premedication with tiapride the rate of dizziness is decreased, the rate of headache is not diminished, but the headaches are very slight. Nausea and vomiting are suppressed by the premedication.

Evaluation and management of the dizzy patient remains frustrating to both the patient and physician. Numerous disorders may induce dizziness; these include not only inner ear disoders but also various central nervous system, ocular, and general systemic disturbances. Since dizziness has many variations, the subtle nuances the symptom may manifest must be explored throughly. Similarly, a consistent approach to the patient's physical and larboratory examination must be taken to understand the pathophysiology of the dizziness. This includes comprehensive auditory and vestibular evaluation, complete neurologic and ophthalmologic examination, and laboratory evaluation for latent or manifest systemic disease. The management of dizziness and vertigo is largely symptomatic. Certain exceptions exist where specific medical and surgical approaches may be beneficial, but the limitations of such treatment must be appreciated.

Varying reactions of the vegetative nerve system to various point combinations (for example: vomiting, dizziness, diarrhea, urge to urinate, fatigue or drowsiness, headache), especially to the needling of Tai Chong (Li 3), induced us to perform biochemical studies before and after acupuncture treatment. A group of children and a group of adults were studied. The material studied was urine and blood; from the children, urine only. The following were determined in the urine: indolacetic acid, 5-hydroxy-indol-3-acetic acid, homovanillic acid, and vanillic-mandelic acid; in the blood, tyrosine and tryptophan (free and bound). Individual points with wide influence (He Gu = LI 4; Zu San Li = St 36; Tai Chong = Li 3) and their combination with generally effective points were tested. The needling of Tai Chong especially showed a clear increase in indolamine metabolism. Isolated increases in metabolites of catecholamine metabolism could be correlated with the patient's increased physical activity after acupuncture. Noteworthy is the observation that no significant chemical reactions were evident if local reactions to the needling no longer appeared at the end of a series of acupuncture treatments.

The authors present their observations on treatment with Noveril of nocturnal enuresis in 49 children aged from 6 to 16 years. The drug is a derivative of dibenzodiazepine belonging to the group of thymoleptic agents with an action similar to that of imipramine. Noveril was given in doses from 20 to 100 mg daily during 3 to 9 weeks. In the final evaluation of the drug the frequency of enuresis before, during and after treatment was taken into account. In 25 cases an improvement was observed, usually in psychogenic nocturnal enuresis. Side effects included oral dryness, headaches and dizziness, and sleep disturbances observed in 4 cases. The tolerance of the drug was good. Noveril has a favourable effect in children with nocturnal enuresis, particularly of psychogenic origin.

A stystematic neurological and electroencephalographical follow-up study in 344 head injured adults gave the following results: 1. 52% of all the hospitalized (mostly primarily amnesic) patients had a cerebral contusion. A contusion was assumed in cases with focal neurological signs (13%), amnesias of more than 8 hours (16%) and/or EEG-abnormalities lasting for more than 24 hours (49%). 2. Traumatic EEG-abnormalities were general slowing (43%) and foci (32%). In 40% of the cases with general slowing the slowing (greater than or equal to 1.5/sec) was within the alpha-frequency band and could only retrospectively be assed. 3. The EEG was invariably abnormal in cases with an amnesia exceeding 8 hours. If the amnesia exceeded 1 hour abnormalities were found in 73%. 4. Among the patients with contusion 6.5% had no amnesia, 48% less than 30 minutes and only 30% an amnesia for more than 8 hours. In 75% of the patients with concussion amnesia lasted less than one hour. 5. Skull fractures were mostly combined with contusion (74%). 6. Impaired drive, reduced ability to concentrate, memory deficits, headache and dizziness were significantly more frequent 6 months after contusion than after concussion. 7. 21% of the patients with traumatic dizziness (44%) had a labyrinthine contusion. 8. Among the contusions diagnosed with the aid of EEG recordings 58% would have been missed after exclusive neurological examination and 82% after application of the classical criteria used by surgeons and general practitioners.
