Transient sexual consciousness

Introduction Transient sexual obscurity is a symptom associated with cooking syndrome. In addition, it can be accompanied by concomitant palpitations and sinus tachycardia, dizziness, and severe headache and vomiting. Cooks syndrome was first reported by Kwork. After eating Chinese food, a combination of symptoms - "burning", "pressing", "tightening" or "numbing" on the face, neck, upper chest, back and arms "I feel a sense of sensation or general fatigue, accompanied by a palpitative paroxysmal symptom, called Chinese restaurant syndrome." Its alias is still delicious syndrome, Chinese headache, eating Chinese food syndrome, Japanese restaurant syndrome. In the past, there was also a syndrome called glutamate intake.

Cause

(1) Causes of the disease:

The cause of this disease is unknown, and it is related to eating Chinese food.

(2) Pathogenesis:

1. Ingestion of Chinese food: Some scholars believe that high sodium in Chinese food produces temporary hypernatremia, which causes low potassium in the cells, leading to muscle paralysis, weakness, palpitations, thirst and vascular headache. Many reports suggest that oral monosodium glutamate (monosodium glutamate MSG) is the cause of this disease. Previous trials have shown that a single intake of MSG more than 1.5g can cause disease (most people take 5 ~ 6g, up to 12g), and the threshold of onset of intravenous injection of MSG is 125mg, the greater the intake of symptoms The heavier. In the investigation, some people still had no disease after eating 21g of MSG. Ghadimi et al believe that: 1 the symptoms are similar to the symptoms and signs induced by acetylcholine; 2 the role of anticholinergic agents and cholinesterase inhibitors, support the hypothesis that this symptom is "temporary" acetylcholine; 3 in the induction of acetylcholine In the plasma cholinesterase activity pattern is similar to the pattern after ingestion into MSG. Gore et al. believe that it is not simply due to the intake of MSG, but the result of ingestion of MSG and other unrecognized substances, or the result of ingestion of certain substances that are completely unrelated to MSG.

2. Genetic factors: There are also hereditary and individual differences. L-glutamate is a neuro-humoral transmitter with a large central nervous system and is harmless to the human body. However, when the animal is given a large amount of L-glutamic acid, it has various effects: the white mice can cause necrosis of the brain, especially the hypothalamus; the mature mice can cause obesity and endocrine gland lesions; for rats and mature dogs, it can cause Abnormal sleep EEG and myoclonic seizures as well as abnormal electroencephalograms of tonicity and even clonic convulsions. In addition, it has been shown that pyridoxine (vitamin B6) can aggravate this abnormal change. This may be a metabolic abnormality of -aminobutyric acid (GABA) and pyridoxine phosphate after a large intake of L-glutamic acid, but its effect on the human body is not necessarily the same as that of animals.

In 1993, the 19th meeting of the UN Food and Agriculture Organization of Food Additives announced that MSG is harmless. Can be removed from the previous regulations on adult food MSG restrictions, to determine that it is a reliable food additive, except for infants within 1 year of age, other age groups are edible. This conclusion is based on extensive research. The investigation found that the "Chinese restaurant syndrome" was not caused by the Chinese cuisine with more MSG, but by the contamination of the food by Bacillus cereus. The performance of MSG is stable under cooking temperature conditions, and there is no need to worry about deterioration and toxicity.

A diagnosis of transient sexual ignorance:

The patient developed symptoms 10 to 45 minutes after each meal, and also occurred 30 minutes to 1 hour after eating. There are many clinical manifestations, and the symptoms of each patient are different. The following aspects are summarized:

1. Head symptoms: there are slamming, beating, pliers, squeaky, dull pain, band headache, seeing headache, snoring headache, constrictive headache; neck tingling and neck The back, upper back, and forearm are released; tears, periorbital fibrotic contracture, sputum pain, squeaky tension, masseter muscle, and sacral muscle tension; face with cold sweat, tightness and numbness, flushing, tingling and warming Heat sensation; numbness of the jaw is released to the subject.

2. Symptoms of the subject: cauterization or numbness, radiation to the arms, chest and back, and muscle pain to the upper shoulders, shoulder blades and upper spine.

3. Upper limb paresthesia: Second, triceps pain, shoulder strap "simulation".

4. Chest symptoms: cold sweat in the chest, discomfort under the sternum.

5. palpitations and sinus tachycardia.

6. Others: generalized burnout, sometimes dizziness, convulsions and nausea, severe sexual sensation and severe headache and vomiting.

Diagnosis can be made according to the above-mentioned clinical manifestations after eating Chinese food or a meal cooked in traditional Chinese way, and closely observing the symptoms and rapid improvement of symptoms.

Differential diagnosis

Symptoms of transient confusion and confusion:

This symptom has neither fever nor diarrhea, but is characterized by neurological symptoms. Comprehensive medical history and epidemiological investigation data should be combined with acute food poisoning and food allergy.
