BACKGROUND: Pruritus, which is a frequent accompanying symptom of dermatological diseases, is also common during pregnancy, either localized or generalized. It may be related to specific dermatoses of pregnancy. OBJECTIVE: A clinical study was performed to know the exact nature of pruritus in pregnancy. METHODS: Subjects with systemic diseases, or laboratory abnormalities were excluded. People who have had pruritic dermatologic diseases before pregnancy were also excluded. One hundred and fifty five pregnant women were interviewed with physical examinations and followed up to the date of delivery. Pruritus was graded. RESULTS: Pruritus was present in 31.6%. Most affected subjects had mild or moderate severity. The abdomen was the most common site. There was a tendency for the duration of itching to increase with the duration of pregnancy. CONCLUSION: Conclusion: These findings may provide basic and useful data on pruritus during pregnancy.

The effects and interactions of metabolic and respiratory acid-base changes on electrically-evoked twitch response, train-of-four and tetanic stimulation with pipecuronium (Pip), vecuronium (Vec) and atracurium (Tra) were studied in the isolated rat hemi-diaphragm preparation. pip (3X10(-7) - 4X10(-6) M), Vec (3X10(-6) - 15X10(-6) M) and Tra (10(-6) - 3X10(-5) M) decreased the electrically-evoked (phrenic nerve stimulation, 0.1 Hz, 0.2 ms, 10 V) twitch response in a dose related fashion and Pip was more potent than Vec and Tra. In the alkali state (pH 7.6 or high HCO3 ), the decrements of twitch response, train-of-four and tetanus ratio induced by Pip (1.5uM) were potentiated, but the effects of Vec or Tra were markedly intensified by acid midium (pH 7.2 or low HCO3 ). And also, decreasing pH by increasing PCO2 or by decreasing HCO3 intensified the effects of Vec and Tra, whereas it reversed by Pip. Conversely, increasing pH by decreasing PCO2 or by increasing HCO3 antagonized the effects of Vec and Tra, whereas it potentiated the Pip effect. On the basis of these finding, the result of the present study suggest that neither PCO2 nor HCO3 has a specific action, but that changes in pH may be responsible for the results. In addition, the differences of the above results by each drugs may not be due to the number of quaternary ammonium of the agents. And also, indicate that the effective site of the influence of the acid-base change upon the neuromuscular blocking effects might be prejunctional nerve terminal.

Although basic mechanisms of atopic dermatitis remain largely speculative, many studies on pathogenesis suggest the importance of food and inhalent allergens. To evaluate the frequency of food and house dust mite hypersensitivity and differences in this frequency according to ages, we measured the levels of specific IgE antibodies to egg white, egg yolk, milk, soy, and house dust mites in 119 children with atopic dermatitis. The results showed that 53% of patients had positive RAST to any one kind of allergens. The frequency of food and house dust mite hypersensitivity were 34.5%, 30.3 %, respectively. Among allergens, house dust mites and egg white are the most prevalent allergens in all atopic dermatitis patients. The Prevalence of egg white is most common under the age of 2 years, but those of house dust mites are the dust mites are the highest in the ages of 5-12 years. In conclusion, we recommend an egg restriction diet in atopic dermatitis patients who are less than 2 years old when their symptoms do not improve with general skin care.

Background: The importance of establishing a regional stroke safety net for the treatment of acute stroke is increasingly emphasized. In this study, we analyzed effectiveness of transferring the suspected acute ischemic stroke (AIS) patients through the 1899-0215 hotline system from 119 ambulances and nearby hospitals. Methods: From July 2015 to July 2022, we analyzed data from 632 suspected acute stroke patients through the hotline. Furthermore, we investigated the proportion of patients in the target population who were eligible for reperfusion therapy and compared cases transferred by 119 emergency services (EMS) with those transferred from nearby hospitals. Results: Six hundred thirty-two suspected acute stroke patients were transferred to our stroke center through the 1899-0215 hotline system. The accuracy of diagnosing acute stroke among transferred patients is 81.0% for 119 EMS and 80.5% for cases transferred from nearby hospitals. Of the 200 patients transferred from hospitals, they were transferred from 47 nearby hospitals with an average transfer distance of 38.2 km and an average transfer time of 65 minutes. Among 291 patients diagnosed with AIS, The onset-to-door time was significantly shorter (p<0.01) for patients transferred by 119 EMS. The proportion of patients who received reperfusion therapy was significantly higher (p<0.01) for those transferred by 119 EMS. Conclusions The hotline service will become a useful tool for establishing a regional stroke network in the Busan area, and its effectiveness will be particularly useful for 119 EMS. Measures are needed in the Busan metropolitan region to ensure the speediness of transferring acute stroke patients between hospitals.

The authors has investigated the effect of intracisternal urokinase on the multihemorrhage canine model of chronic post-subarachnoid hemorrhage(SAH) hydrocephalus. Each of 16 adult mongrel dogs was assigned to one of two experimental groups. All animals received a total of 13ml of fresh unheparinized autologous blood via three cisternal injections. Eight animals were treated by intracisternal injection of 20,000 IU of Urokinase every 12 hours for 3 days, and the remaining were not treated. The changes in ventricular volumes were measured by computed tomography(CT) before and 3 months after the initial subarachnoid blood injection. To compare the changes of hydrodynamic properties in chronic phases of post-SAH hydrocephalus, the pressure-volume index(PVI) technique of bolus manipulation of cerebrospinal fluid(CSF) was used to measure the volume-buffering capacity of neural axis and the resistance to the absorption of CSF(before SAH, post-SAH 1 month, 3 months). The final ventricular volume at 3 months of control group was 4 times greater than the initial volume, but Urokinase group less than two times. The mean measured PVI values of control group and Urokinase group were 3.98+/-0.76ml(+/- standard deviation(SD)) and 4.01+/-0.82ml in baseline study, 3.09+/-0.96ml and 3.70+/-0.84ml in post-SAH 3 months. The mean resistance of CSF outflow of control group and Urokinase group were 10.30+/-2.24mm Hg/ml/min), and 10.34+/-1.98mm Hg/ml/min in baseline study. At 1 month and 3 months after SAH control group maintained high absorptive resistance(29.54+/-11.50mm Hg/ml/min, 22.43+/-3.82mm Hg/ml/min), whereas the resistances of Urokinase group were slightly increased and then returned to the original levels(16.04+/-4.87mm Hg/ml/min, 12.87+/-3.06mm Hg/ml/min). The results described in this experimental study indicated that if fibrinolysis of the subarachnoid blood clot can be achieved rapidly after SAH, the complicating chronic hydrocephalus might be prevented.

Spinal ependymomas originate in the ependymal lining and grow rather slowly which allows them to reach considerable size and length. The great majority of primary tumors of the cauda equina are ependymomas and show a rather marked predilection for the male. Histologically ependymomas are benign but merastasis and anaplasia have been reported. The basic architectural structures of the ependymoma are the ependymal rosettes and pseudo-rosettes. Intradural spinal arteriovenous malformmations are relatively rare lesions and found only at autopsy or incidentally during surgical operations before the advent of investigative procedure. Development of myelography and spinal angiography have shown that vascular malformations of the spinal cord are not rare. Male is more predominant than female. The etiology and pathophysiological mechanisms are uncertain but many authors have believed that congenital, trauma, inflammations, tumoral processes, vasculitis and abnormal posture are influenced on A-V malformations of the spinal cord. No reports have been noticed about giant ependymomas of the cauda equina combined with spinal A-V malformations. We have experienced a case of giant ependymomas of the cauda equina associated with thoracic intradural spinal A-V malformations in forty-two year-old male and reviewed the literatures.

A 61-year-old woman with a history of asthma and pulmonary tuberculosis was presented with purulent bloody sputum. She was treated as having lung abscess initially, but her signs and symptoms did not improve with traditional therapy. Finally, in the clinical course and laboratory data during hospitalization, she was diagnosed as ABPA with coexistent aspergilloma. Thereafter she was treated with itraconazole for aspergilloma, and corticosteroid for ABPA. The symptoms of hemoptysis and dyspnea were improved. A case of ABPA with coexistent aspergilloma and a brief review of the literature were presented.

Electrical stimulation of the cerebellar fastigial nucleus(FN) increases cerebral blood flow(CBF) and reduces brain damage after focal cerebral ischemia. The authors studied whether the neuroprotection elicited from electrical stimulation of the cerebellar FN is attibutable to the elevation in regional CBF(rCBF) or reduction in release of excitatory amino acid sprague-Dawley rats were anesthtized with a mixture of halothane(3% for the indurction and 1% for maintenance) and oxygen and artificially ventilated through a tracheal cannula. Arterial pressure, blood gases and body temperature were monitored. The middle cerebral artery(MCA) was occluded distal to the lenticulostriate branches. The FN was then for 2 hours, over the regions corresponding to the ischemic core and penumbra. Postiischemic release of glutamate and aspartate were measured by microdialysis for 2 hours at the same site of measurement of rCBF. Infarct volume was determined 8 hours later in 2,3,5-triphenyl tetrazolium chloride(TTC)-stained sections FN stimulation(n=12) increased mean arterial pressure by 28+/-16mmHg. In nonstimulated control rats(n=12), mean AP was not changed significantly during the experimental procedures. Compared with nonstimulated animal, stimulation of FN for 1 hour following MCA occlusion siginficantly increased rCBF in ischemic core and penumbra by 53.6% and 67.6% respectively. And the volume of infarction decreased by 42% at 8 hours after MCA occlusion. The concentration of glutamate and aspartate in ischemic core after MCA occlusion increased both in the control group(to 12.2+/-3.3 folds and 10.4+/-4.1 folds respectively) and in the stimulation group(10.5+/-2.8 and 11.2+/-4.1 folds, respectively). The concentration of glutamate and aspartate in penumbra did change significantly neither in the control group(to 2.5+/-1.3 folds and 1.8+/-0.6 folds respectively) nor in the stimulation group(1.9+/-0.5 folds and 2.1+/-0.4 folds, respectively). There was no significant difference between the two groups.
