The "child-to-child" activity pages are intended to assist teachers, health agents, and other community agents in their work and to help children understand how they themselves can improve the health of other children and their community. The objective of this activity page is to teach children to recognize the signs and dangers of dehydration and to treat it with oral rehydration fluid. Simple activities are suggested to illustrate the signs of dehydration. A drawing or list of signs of dehydration for children should include fatigue, sunken eyes, thirst and dry tongue and mouth, failure of the skin to return to normal when pinched, and infrequent or no urination. Signs of danger requiring immediate medical attention include diarrhea of more than 3 days, intense vomiting preventing drinking, puffed up face and feet, convulsions, and too deep sleep. The children should be shown how to make the oral rehydration fluid and instructed to make just enough for 1 day. The solution should be given in small quantities at least every 15 minutes. 200 ml should be given after each liquid stool and at least 1 liter every 24 hours for a child. Infants should continue to breastfeed and older children should be given semiliquid foods. An already dehydrated or vomiting child should be given small amounts of solution night and day every 3-5 minutes until normal urination is resumed.

Sarin (O-isopropylmethylphosphonofluoridate) is a highly toxic nerve agent produced for chemical warfare. Sarin is an extremely potent acetylcholinesterase (AchE) inhibitor with high specificity and affinity for the enzyme. Death by sarin is due to anoxia resulting from airway obstruction, weakness of the muscles of respiration, convulsions and respiratory failure. The main clinical symptoms of acute toxicity of sarin are seizures, tremors and hypothermia. Exposure to sarin during incidents in Japan in 1994, 1995 and 1998, and possible exposure to low levels of sarin during the Gulf War, resulted in the deaths and injury of many people in Japan and caused possible long-term health effects on Gulf War veterans. Symptoms related to sarin poisoning in Japan still exist 1-3 years after the incident and include fatigue, asthenia, shoulder stiffness and blurred vision. Sarin produced seizures in rats and pigs. Recent studies showed that long-term exposure to low levels of sarin caused neurophysiological and behavioral alterations. Toxicity from sarin significantly increased following concurrent exposure to other chemicals such as pyridostigmine bromide. Further research to examine effects of sarin on the cellular and the molecular levels, gene transcription, endocrine system as well as its long-term impact is needed.

'Maqianzi' (the dried ripe seed of Strychnos nux-vomica L.) contains 1.0-1.4% each of strychnine and brucine. After processing to reduce its toxicity, 'maqianzi' was used as a herbal remedy for rheumatism, musculoskeletal injuries and limb paralysis. A 42-year old woman with neck pain was prescribed 15 g of 'maqianzi' to be taken in two doses at 7 hours apart, although the recommended dose was 0.3-0.6 g. She was apparently well after drinking the first of two bowls of 'maqianzi' decoction. One hour after she drank the second bowl of herbal decoction, she suddenly developed tonic contractions of all her limb muscles and carpopedal spasm lasting 5 min, difficulty in breathing, chest discomfort and perioral numbness. The second bowl of decoction probably became more concentrated because of evaporation of water during continued boiling and contained a larger amount of 'maqianzi'. On arrival in the hospital 1 hour later, she complained of muscle pain and tiredness. She was found to have hyperventilation and weakness of four limbs, with muscle power of grade 5(-)/5. All her symptoms gradually subsided over the next few hours. This case illustrated that 'maqianzi' can cause strychnine poisoning even after processing, especially when the recommended dose is greatly exceeded. In any patient with 'unexplained' muscle spasms or convulsions, strychnine poisoning should be included in the differential diagnosis and they should be asked about the use of herbal medicines.

We evaluated the results of medical treatment for male prolactinomas. We encountered eight patients with male prolactinomas. The age was 25 to 54 years old (mean 43 years) and the chief clinical symptoms were visual acuity/field defect in three patients, pituitary apoplexy in one patient, disturbance of ejection in one patient, generalized convulsion in one patient, headache in one patient and general fatigue in one patient. The serum prolactin level was 279 to 7,360 ng/ml (mean 2,832 ng/ml). The tumors in all patients were large with a mean diameter of 34.9 mm (range, 21 to 43 mm). In only one patient, the operation was performed due to pituitary apoplexy. All the patients were treated by medication, with bromocriptine being used in seven patients and terguride in one. The follow-up period was 0.8 to 13 years (mean 5.9 years) and, in all patients, the medical treatment was continued. The tumor decreased in size in all patients and the serum prolactin level at the last follow-up observation was 0.5 to 70.5 ng/ml (mean 26.9 ng/ml). All the neurological symptoms disappeared in the early stage of treatment. As for the complications of medical treatment; in one patient, orthostatic hypotension occurred during the initial administration of bromocriptine and one patient suffered CSF leakage two months after the administration of bromocriptine, so the repair of the sella floor by transsphenoidal surgery was necessary. The medical treatment for male prolactinomas is effective for a long term and should be the primary treatment for the male prolactinomas. In conclusion, patients can maintain a good quality of life for a long time by using dopamine agonists.

The care of children at the end of life is gradually improving. Nevertheless, more than half suffer from intractable symptoms before dying. Although pain has been the subject of clinical research, evidence-based data are almost completely lacking for other symptoms, highlighting the need for clinical research in palliative care. We review the available evidence on fatigue, anorexia, dyspnea, respiratory secretions, cough, constipation, mouth dryness, urinary obstruction, terminal convulsions and gasping. When evidence is lacking, we offer our empiric approach. Short duration benzodiazepines have become an important component of treatment that should remain simple, while providing the dying child the comfort needed to experience the highest quality relationships with those around him.

Pituitary hormones have an important role during exercise yet relatively little is known about the stimulus for their release. Body temperature progressively increases during prolonged steady-state exercise in the heat and we have investigated the role that this may play in the release of prolactin, growth hormone and cortisol (as an indicator of adrenocorticotropic hormone) into the circulation. Fit young male subjects exercised at 73% V(O2,max) until volitional fatigue at 20 degrees C and at 35 degrees C (30% relative humidity at both temperatures). Rectal temperature and mean skin temperature were monitored and blood samples analysed for lactate, glucose, cortisol, growth hormone and prolactin concentrations. During the first 20 min, core temperature rose continuously and to a similar extent at both temperatures, while mean skin temperature was approximately 4 degrees C lower during exercise in the cool. Blood glucose concentration was essentially constant throughout the period of exercise while lactate concentration increased in the first 10 min and then remained constant with very similar changes in the two exercise conditions. Prolactin and growth hormone concentrations both increased during the exercise period while the concentration of cortisol declined slightly before rising slightly over the 40 min period. Prolactin release was significantly greater when exercise was carried out in the heat while there was no difference in the release of growth hormone or cortisol in the two conditions. When plotted as a function of rectal temperature, growth hormone concentration showed a linear relationship which was the same at ambient temperatures of 35 degrees C and 20 degrees C. Prolactin concentration had a curvilinear relationship with rectal temperature and this differed markedly at the two ambient temperatures. Cortisol concentration showed no dependence on any measure of body temperature. Our results are consistent with some aspect of body temperature being a stimulus for growth hormone and prolactin secretion; however, the precise mechanism clearly differs between the two hormones and we suggest that skin temperature modulates prolactin release, but does not affect the release of growth hormone.

Despite being banned in many countries and having its use severely restricted in others, pentachlorophenol (PCP) remains an important pesticide from a toxicological perspective. It is a stable and persistent compound. In humans it is readily absorbed by ingestion and inhalation but is less well absorbed dermally. Its distribution is limited, its metabolism extensive and it is eliminated only slowly. Assessment of the toxicity of PCP is confounded by the presence of contaminants known to cause effects identical to those attributed to PCP. However, severe exposure by any route may result in an acute and occasionally fatal illness that bears all the hallmarks of being mediated by uncoupling of oxidative phosphorylation. Tachycardia, tachypnoea, sweating, altered consciousness, hyperthermia, convulsions and early onset of marked rigor (if death occurs) are the most notable features. Pulmonary oedema, intravascular haemolysis, pancreatitis, jaundice and acute renal failure have been reported. There is no antidote and no adequate data to support the use of repeat-dose oral cholestyramine, forced diuresis or urine alkalinisation as effective methods of enhancing PCP elimination in poisoned humans. Supportive care and vigorous management of hyperthermia should produce a satisfactory outcome. Chronic occupational exposure to PCP may produce a syndrome similar to acute systemic poisoning, together with conjunctivitis and irritation of the upper respiratory and oral mucosae. Long-term exposure has also been reported to result in chronic fatigue or neuropsychiatric features in combination with skin infections (including chloracne), chronic respiratory symptoms, neuralgic pains in the legs, and impaired fertility and hypothyroidism secondary to endocrine disruption. PCP is a weak mutagen but the available data for humans are insufficient to classify it more strongly than as a probable carcinogen.

The purpose of the present study was to investigate the factorial validity of the Brunel Mood Scale, which measures anger, confusion, depression, fatigue, tension, and vigor, for water-skiers. Participants were 345 water-skiers (age range 16 to 39 years, men: n=311, women: n=34) who completed the scale approximately 1 hour before a water-skiing competition. Confirmatory factor analysis indicated support for the validity of the 6-factor model, with a Comparative Fit Index of .90 and Root Mean Squared Error of Approximation of .07. Internal consistency coefficients were above the .70 criterion. It is suggested that the Brunel Mood Scale shows factorial validity for use with water-skiers and that researchers should continue to assess validation of the Brunel Mood Scale with other measures and with specific appropriate samples.

Somatic symptoms and anxiety symptoms are often disregarded in the detection of depression in primary care. The present investigation examined to what extent somatic and anxiety symptoms recorded with the Composite International Diagnostic Interview-Primary Health Care Version (CIDI-PHC) can improve the detection of depression as compared to the General Health Questionnaire-12-item version alone. Data from the World Health Organization study on Psychological Problems in General Health Care were used. The study sample consisted of primary care attenders from 15 centres from all over the world who underwent a psychiatric examination with the CIDI-PHC. Medically unexplained somatic symptoms (back pain, feelings of heaviness/lightness in parts of the body, periods of bodily weakness, seizures/convulsions, permanent tiredness, exhaustion after a minimum of effort) and-to a smaller extent-diverse anxiety symptoms (e.g. feelings of anxiousness/nervousness, feelings of tension, difficulties relaxing) significantly contributed to the detection of depression in a logistic regression analysis. The results confirm the observation that in primary care somatic symptoms play an important role in the manifestation of depressive disorders. The items investigated herein could prove beneficial for future depression screening instruments to improve the detection of depressive disorders in primary care.

We described a case of shaken-baby syndrome with multiple chronic subdural hematomas. A 10-month-old male baby was admitted to our hospital because of loss of consciousness and convulsions. CT scan revealed an acute subarachnoid hemorrhage extending into the interhemispheric fissure and supracerebellar space. The patient was treated conservatively, and discharged from the hospitaL Two months after ictus, a baby was admitted to our hospital with general fatigue. CT scan demonstrated multiple chronic subdural hematomas. Burr hole irrigation and drainage brought about complete disappearance of these lesions. Retrospectively, it was found that these multiple subdural hematomas were due to shaken-baby syndrome. Shaken-baby syndrome is a form of child abuse that can cause significant head injury, and subdural hematoma is the most common manifestation. It is well known that the outcome of shaken-baby syndrome is generally not good. It is important to suspect shaken-baby syndrome when a chronic subdural hematoma is seen in a baby.
