1.A comparative clinicopathological study of pityriasis lichenoides chronica and small plaque parapsoriasis.
Korean Journal of Dermatology 1991;29(1):41-49
A clinicopathological study of 12 cases of pityriasis lichenoides chronica and 14 cases of small plaque parapsoriasis was performed. Patients with pityriasis lichenoides chranica ranged in age from 15 to 62 years (mean, 30 years) with male predominance. They had erythematous or reddish scaly papules occuring mostly on both trunk and extremities(92%). The lesions were about the size of r ice grains or small peas. Patients with small plaque parapsoriasis ranged in age from 8 to 67 years(mean, 33 years) and presented yellowish or erythematous scaly maculies and patches comrnonly involving the trunk and extremities(64%). The size of the lesions were larger than those of pityriasis lichenoides chronica. Histopatbologically, the distinct feature of pityriasis lichenoides chronica was vacuolar alteration at the dermoepidermal junction characterizing interface dermatitis. The microscopic findings of small plaque parapsoriasis were, although not as distinct as in pityriasis lichenoides chronica, those af either spongiotic dermatitis or superfirial peri vascula dermatitis. We conclude from this study that these two conditions have different clinical and histologic features and we propose that the term guttate parapsoriasis shauld not be used as a synonym of either pityriasis lichenoides rhronica or small plaque parapsoriasis.

Traumatic epidermoid cysts are rare tumors occuring almost exclusively on the palms, palmar aspects of fingers, and soles. These cysts are thought to originate from a bit of epidermis implanted into the dermis after a penetrating or blunt wound. We report a case of typical traumatic epidermoid cyst on the sole of the right foot of a 23-year-old male student. The lesion was a coin-sized, tender, fluctuating cystic mass occuring 3 years after a penetrating wound by an iron nail. Histopathlogical examination revealed a deep dermal cyst lined by a thick, flattened, keratinizing wall with partial disruption accompanied by foreign-body reaction.

A 23-year-old woman had solar urticaria that was activated by visible light and UVA, but the intensity of the urticarial reaction of visible light was more pronounced than that of UVA. The results of passive and reverse passive transfer studies were negative, We report a case of solar urticaria which is characterized by overlapping features of 60th type Il and Il[ in the classification of Harber.

A case of severe aseptic meningitis with communicating hydrocephalus following iotrolan myelography is presented. The patient's condition improved very quickly after corticosteroid therapy. Rapid improvement and absence of pathogenic organisms in the CSF culture strongly favor an aseptic meningitis. This is the first reported case of aseptic meningtis with the secondary development of hydrocephalus caused by iotrolan myelography.

BACKGROUND: The electrophysiological effects of purinergic receptor agonists, adenosine triphosphate(ATP) and adenosine were examined using conventional microelectrode technique in rat atrial muscle fibers under superfused with a normal or a simulated ischemic(hypoxic, hyperkalemic and acidotic) physiologic salt solution(PSS) in vitro. METHODS: Action potential parameters, such as maximal diastolic potential(MDP), action potential amplitude(APA), rate of phase 0 depolarization(dv/dtmax) and action potential duration(APD90) were measured in electrically paced, physiologic salt solution(Tyrode's) superfused left rat atrium. In the experiment of ischemic simulation in vitro, normal physiologic salt solutions(NPSS0 were modified(MPSS) and superfused in substitute for normal Tyrode's solution. To investigate the effects of purinergic receptor agonists, ATP or adenosine was added to the superfused tyrode's solutions(NPSS or MPSS) in molar concentration. RESULTS: Under superfused with normal PSS, ATP(10(-3), 10(-4)M) elicited slight hyperpolarization in MDP, and both ATP(10(-6)-10(-3)M) and adenosine(10(-6)-10(-3)M) shortened the duration of normal action potential in a dose-dependent manner. The other paramaters were not affected by the drugs. Superfusion with ischemic PSS caused reductions in MDP as well as APA, dv/dtmax and, especially, APD90. The effects produced by the initial 10 minutes of superfusion with ischemic PSS almost completely disappeared during a subsequent period of continued superfusion with normal PSS, but, those by the initial 20 min lasted in some degree. Both ATP(10(-4)M) and adenosine(10(-4)M) attenuated the reduction in the rate of phase 0 depolarization and the amplitude of the action potential amplitude produced by the ischemic PSS. CONCLUSION: Purinergic receptor agonists, ATP and adensoine, caused a concentration-dependent shortening of the action potential duration in rat atrial muscle fibers and they attenuated the reductions in the rate of phase 0 depolarization and action potential amplitude in fibers superfused with ischemic PSS.
