A 42-year old man was admitted for treatment of a fracture of the medial condyle of the left femur. After 10 days of cast immbilization of the above mentioned extremity, erythematous papulo-vesicular eruption was noted under the external splintage. We concluded that this was an unusual allergic contact dermatitis which is caused by CaSO4.1/2H20, and proved it by patch test in our clinic.

PURPOSE: To evaluate the success rate of conventional skin dacryocystorhinostomy(DCR), the success rate and postoperative complications were evaluated after the follow-up period of 6~72 months(average 16.7 months), and compared with those of our previous reports on endonasal DCR, at postoperative 6 months(PO6M) and 12 months(PO12M). METHODS: skin DCR was performed in 76 patients, 89 eyes between July 1993 and June 2000 at the Department of Ophthalmology, Yeungnam University College of Medicine. RESULTS: Primary success rate of skin DCR was 93.3%, and the final success rate after revision of mucosal ostium revealed 96.6%. Postoperative complications included 7 cases of silicone tube protrusion and 4 cases of mucosal ostium obstruction. CONCLUSIONS: Primary success rate of skin DCR was 93.3%, and those of endonasal DCR were 92.3%(PO6M) and 89.8%(PO12M). The final success rate of skin DCR was 96.6%, and those of endonasal DCR were 98.4%(PO6M) and 99.2%(PO12M).

Dissociated vertical deviation(DVD)is a kind of vertical strabismus of an upward drift of a nonfixating eye, and requires operation when it is cosmetically unacceptable. The authors compared the results of unilateral superior rectus recession with those of bilateral recession in the treatment of DVD, and analyzed the effects and complications of the superior rectus recession. The charts of 58 patients(94 eyes)who underwent superior rectus recession for DVD were retrospectively reviewed, and minimum follow-up was 6 months after operation. In 22 patients, the recession was performed unilaterally, and in 36 patients bilaterally. Satisfactory alignment under 9 PD was obtained in 77.3%of the unilateral cases and 77.8%of the bilateral cases. DVDs developed in unoperated eye in 9 unilateral cases. Graduated superior rectus recession was a quite predictable and effective procedure in the treatment of DVD. In unilateral surgery, it is important to keep in mind that the unmasking of DVD in the fellow eye can occur, but unilateral surgery may be indicated if only when the obvious deviation is diagnosed preoperatively in one eye.

Acute cerebral infarctions are rare in children, however, they can occur as a complication of a Mycoplasma pneumoniae (MP) infection due to direct invasion, vasculitis, or a hypercoagulable state. We report on the case of a 5-year-old boy who had an extensive stroke in multiple cerebrovascular territories 10 days after the diagnosis of MP infection. Based on the suspicion that the cerebral infarction was associated with a macrolide-resistant MP infection, the patient was treated with levofloxacin, methyl-prednisolone, intravenous immunoglobulin, and enoxaparin. Despite this medical management, cerebral vascular narrowing progressed and a decompressive craniectomy became necessary for the patient's survival. According to laboratory tests, brain magnetic resonance imaging, and clinical manifestations, the cerebral infarction in this case appeared to be due to the combined effects of hypercoagulability and cytokineinduced vascular inflammation.

BACKGROUND: Some of the deficiencies in anterior pituitary function identified in subjects with macroadenomas appear to represent irrevemible necrosis of normal pituitary cells, and in addition reversible damage to viable glandular tissue and/or incomplete interruption of local circulation by compression of pituitary stalk may also contribute significantly to hypopituitarism. So anterior pituitary function may actually improve in some patients undergoing successful tumor resection or reduction in tumor size. Although direct comparisons of pituitary function among the various pituitary tumors are not presently available it was reported that there is some difference in the degree of pituitary impairment between patients with nonfunctioning macroadenoma(NFMA) and those with GH-secreting macroadenoma(GHMA).In this study, to investigate the difference in the degree of hypopituitarism we compared anterior pituitary function in subjects with NFMA to that in patients with GHMA. METHODS: In this retrospective study, preoperative and postoperative anterior pituitary function was assessed by clinical findings, basal hormone levels and/or combined pituitary stimulation test in 29 subjects with NFMA and in 24 subjects with GHMA. RESULTS: 1. There was no difference in age, sex, tumor size distribution between the two groups. 2. Preoperatively, NFMA patients had a higher prevalence of secondary hypothyroidism(34% vs. 5%; p(0.02) compared to subjects with GHMA. Patients with NFMA also had a higher prevalence of more severe pituitary failure compared with acromegalic patients; 48% of the patients in this group had more than one pituitary hormone axis impaired compared to 17% in the acromegalic group(p0.03). 3. Postoperatively, NFMA patients also had a higher prevalence of secondary hypoadrenalism (52% vs. 11%; p 0.01) compared with acromegalic patients. Additionally, the prevalence who had more than one pituitary hormone axis impaired was still greater in NFMA patients than in the acromegalic group(57% vs. 22%; p=0.054). 4. No correlation was found between the severity of pituitary failure and tumor size or extension in both groups before and after surgery. CONCLUSION: These findings suggest that anterior pituitary function is relatively better preserved in patients with GHMA than those with NFMA and that this difference is independent of tumor size and extension. The mechanism underlying the lower rate of hypopituitarism in acromegalics with macroadenoma remains to be elucidated.

One of the purposes of this experiment is to observe the structure of crystalline lens with cataract, which is formed artificially, using the light microscope and electron microscope. The other is to observe the differences of structural variations in the cataract developed inside body. Twelve eyes of six pigs were used for this experiment. Two of them are normal crystalline lens, five are cystalline lens in distilled water, and the rest are in balanced salt solution through intact or ruptured capsule. We examined the time of cataract formation and compared the ultrastructural changes. Ruptured capsule and high osmotic pressure difference induced more rapid opacity. In case of distilled water, the capsule is maintained but it is very difficult to distinguish between epithelium and lens fibers. Also, there is a severe crack in the lens fibers. In electron microscopic, as the cataract progresses, the osmotic swelling becomes more prominent. One of the striking changes was a marked intercellular cyst formation. Lens cells became irregular in size and density and were extensively vacuolated. The swelling of the lens cells continuously induced large intracellular vacuoles and liquefied the cytoplasmic protein. In conclusion, the structural change of cataract, which was seen by an electron microscope, resulted from change in osmolarity from previously announced in vivo experiment and structural change resulted from this experiment are similar.

PURPOSE: Acute scrotum is a clinical syndrome that is defined as an acute painful swelling of the scrotum. It is well known that early surgical exploration is needed to prevent the testicular loss when testicu lar torsion breakouts. But most of reports were only focused on testicular torsion of prepubertal age group. This fact let us examine the acute scrotum with all age group and the significance of surgical exploration. MATERIALS AND METHODS: We retrospectively reviewed the results collected from 112 patients (131 cases) with acute scrotum who had been admitted to our hospital between June 1994 and November 1999 with the exception of scrotal trauma. RESULTS: The incidence of acute scrotum over 20 years old was 72.4% of total acute scrotum patients. The most common disease was acute epididymitis giving the rate of 71.8% (94 cases). In adult the incidence of testicular torsion was low (3 cases). Surgical torsion was 12 cases and acute epididymitis was 12 cases as the cause of acute scrotum. CONCLUSIONS: Most cases of testicular torsion have been below 20 years old and only 3 cases have been over 20 years old. Although the incidence of testicular torsion over 20 years old has been low. There were severe infectious diseases needing surgical approach in the cases of aged patient. this research shows that the treatment of acute scrotum goes with the need of surgical therapy.
