BACKGROUND: Stress has long been known to play a role in many dermatologic disorders and can affect the onset and course of the disorder in some patients. Stress-induced exacerbation or onset of symptoms has been reported in chronic urticaria, alopecia areata, herpes simplex, herpes zoster, and psoriasis vulgaris, and these diseases can be classified as stress-associated dermatoses. Beta beta-endorphin is one of the most important mediators of stress, which is known to be generated upon stimulation of the pituitary-adrenal axis, and its secretion increases during periods of stress. OBJECTIVE: In order to see wheather beta-endorphin might be related to the onset or recurrence of stress-associated dermatoses, we compared the plasma concentration of beta-endorphin in patients with stress-associated dermatoses with those of healthy subjects. METHODS: The concentration of beta-endorphin. In sera was quantified by radioimmunoassay, using the INCSTAB 125I RIA Kit for plasma beta-endorphin, Each patient was asked to indicate if they believed that their skin problem began after an important stressful event in their lives. RESULTS: There was no significant difference in plasma beta-endorphin levels between patients with chronic urticaria, alopecia areata, herpes simplex, and herpes zoster and healthy subjects(p>0.05), whereas in patients with psoriasis vulgaris, plasma level of beta-endorphin was significantly increased (p<0.001). There was no relationship between the stressful events and plasma beta-endorphin concentrations. CONCLUSIONS: The plasma beta-endorphin level is not correlated with the onset or recurrence of stress-associated dermatoses such as chronic urticaria, alopecia areata, herpes simplex, and herpes zoster. The increase in beta-endorphin in psoriasis vulgaris is more likely that this peptide is generated by the lymphocyte infiltrated in the skin and/or by lymphocytes when they recirculate rather than by the activation of the pituitary-adrenal axis by stress.

Cytologic findings of pleural effusion in three cases of rhabdomyosarcoma are reported. Case 1 was a pleomorphic rhabdomyosarcoma which had devoped at the chest wall of an elderly male patient and caused pleural effusion. The cytologic features were consistent with pleomorphic rhabdomyosarcoma, that was, showing loose clusters, cellular pleomorphism, and abundant finely vesicular cytoplasm. Cases 2 and 3 were embryonal rhabdomyosarcomas in young adults. Primary site was the oral cavity in case 1, but unknown in case 2 and case 3. The effusion cytology was similar in these cases. Clustered or isolated small round cells with hyperchromatic nuclei and scanty cytoplasm were smeared. The cohesiveness of tumor cells was weak and the cells did not show linear arrangement or nuclear molding. Effusion cytology in a sarcoma patient would be diagnostic when the primary site and the type of sarcoma were already known.

While diverticulosis of the colon is a relatively common disease, a solitary giant colonic diverticulum is rare. Although there exist some theories about the formation of the giant colonic diverticulum, none is really conclusive. The preoperative diagnosis of giant colonic diverticulum is made radiographically with findings of a large, smoothly marginated, round homogeneous radiolucency in the abdomen that is in close apposition to the colon on barium enema examination. Early surgical treatment is necessary since the complication rate is high. One case of giant colonic diverticulum is presented, the clinical, radiologic and pathologic findings are discussed, and the etiology and differential diagnosis, reviewe.
