Soft Contact Lenses(SCL) are used widely instead of glasses among young female, especially university students, for cosmetic purpose. Usually Shirmer test has been used to evaluate the tear production state however more objective method is the tear film break up time. Authors evaluated the effect of soft contact lenses on BUT. We selected 40 femalse wearing on Hyper-Thin soft contact lenses, and One Soflens(Baush and Lomb) as soft contact lens wearing group and 30 females without no evidence of systemic disease or ocular disease affecting on tear production as normal control group. And authors studied mean value of BUT at each group, difference of BUT between 2 groups and finally evaluated the BUT change accord ing to duration of wearing. The results were as follows. 1. The mean value of tear film break up time(BUT) was 8.64 +/- 3.91 seconds and 11.12 +/- 4.94 seconds in soft contact lens wearing group and normal control group respectively. 2. There was a statistically significant difference of BUT between each group(P<0.05). 3. There was statistically significant difference of BUT between more than 4 years of soft contact lens wearing group and less than 3 years of wearing gorup(P<0.05).

To create an experimental glaucoma model in rabbit and to study the effect of elevated intraocular pressure (IOP) on rabbits ocular tissues, we treated trabecular meshwork of 7 adult pigmented rabbits with Q-switched Nd:YAG laser. And then we studied the IOP lowering effect of topical verapamil in experimental glaucoma model. The IOP and outflow facility were measured with an applanation pneumotonograph (Alcon, Texas). During sustained rap elevation, 50ul of 0.25% verapamil was instilled in one eye and normal saline in the fellow eye. The IOP was measured 1, 2, 4, 8 hours after instillation. The measurement was repeated twice at 2 weeks interval. After 5 weeks, the IOP increased from an average baseline IOP of 16.6mmHg to 25.51mmHg, an increase of 55.6%. The outflow facility was decreased from 0.21 microliter/min/mmHg to 0.09 microliter/min/mmHg. There were statistically significant reductions in IOP in both verapamil and placebo-treated eyes(p<0.05). The reduction was greater in verapamil-treated eyes than in placebo-treated eyes(p<0.05). Maximal reduction of IOP was observed 2 hours after single-drop of verapamil, with significant reduction of IOP up to 4 hours duration(p<0.05). During the observation period of this study, cupping of the optic nerve head developed. Histopathologic examination revealed extensive scarring of the anterior chamber angle structure. There are marked hyaline degeneration of retinal ganglion cells in temporal retina.

Nerve fiber bundle index(NFBI) is a new index which detects visual field depression in 21 nerve fiber bundle zones, reflecting the topographical arrangement of visual field defects. We applied this index to 39 eyes with normal visual field and 131 eyes with early glau-comatous field defect(mean defect

The Scheimpflug photography was used to evauate objectively changes in lens opacity at a month interval in 143 eyes of 78 patients affected by early cataract. from Dec. 1993 to Dec. 1994. A total of 48 patients were treated daily with 1.5g bendazac-lysine, and 30 patients constituted the control group. We checked visual acuity and analyzed change of lens opacity by using axial densitometry and retroillumination of Scheimpflug photography after Bendaline(R) medication up to 9 months After treatment, improvement or no change of subjective visual acuity was observed in 65 eyes(78.3%) of treated group, whereas decrement in 35 eyes (58.3%) of control group. In the axial densitometry, the nuclear opacity began to improve after 3 months of medication and opacities of lens between anterior supranucleus and posterior capsule were statistically significant improved after 5 months of medication (p<0.05). There's no correlation in the change of opacity area under retroillumination (p>0.05). The result show that bendazac lysine may be effective in improvement of visual acuity and delay the formation of lens opacity in early cataract.

One of the rarest anomalies of the urinary tract is crossed renal ectopia. In Crossed Renal Ectopia, the kidney may be fused or unfused. The fused type is more common. The Diagnosis is made by a combination of urologic and radiologic technics including intravenous pyelography, Cytoscopic examination, retrograde pyelography and retroperitoneal air insufflation. The treatment of renal ectopia without fusion is that of the complicating disease in a kindney normally placed. This paper presented one care of crossed renal ectopia with fusion in a 5 month old female patient who admitted with high fever, oliguria and a palpable abdominal mass. The literatures were reviewed briefly.

BACKGROUND: Modern intensive chemotherapy has dramatically improved the prognosis of acute lymphoblastic leukemia in children. However, quality of life and even survival may be threatened by infection. Immunosuppression is experted due to disease itself or therapy, and sometimes, immunosuppression itself may lead to reactivation of latent viral infections in these patients. Often the viruses involved in the most severe infections suggest that patients suffer from defect in the cellular immunity. The principal defects that predispose leukemia patients to infection are defects of T cell, B cell, stem cell, complement, and macrophage. These contributing factors interact in a complex manner resulting in spectrum of problems. But these may result from a T cell defect and, in this study, 7 cell responsiveness of patients at diagnosis, remission induction, maintenance chemotherapy and after chemotherapy for leukemia has been investigated. Studies of the immune competence of patients undergoing chemotherapy for leukemia is in progress, but results are different from each other. METHOD: Between July 1994 and May 1996, seventy patients with childhood ALL were enrolled in this study. In order to expect frequency and depth of infection and prognosis, we investigated concentrations of immunoglobulins G, A, M, peripheral total lymphocyte count, 7 cell subsets, phytohemmaglutinin responsiveness, interleukln-2(IL-2), gamma-interferon(gamma-INF), and natural killer cell activity. RESULTS: 1) IgA concentrations were often markedly raised at diagnosis, and IgG, IgM concentrations both were within normal limits. During and after chemotherapy, IgA had fallen significantly but IgG, IgM are within normal limits. 2) Total lymphocyte count had fallen during chemotherapy, and returned to normal levels after chemotherapy. CD4+ T cell were markedly decresed at diagnosis, during chemotherapy and returned to normal levels after chemotherapy. 3) In vitro proliferative response of peripheral blood lymphocytes to the T cell mitogen phytohenagglutinin were impaired at diagnosis, during chemotherapy but did not returned to normal levels. 4) Interlekin-2, gamma interferon were normal levels at diagnosis, and had fallen in the induction of remission and quickly returned to normal levels with the swish to maintenance chemotherapy. But Interleukin-2 had fallen during and after chemotherapy. Natural killer cell activity had fallen at diagnosis, during chemotherapy and returned to normal levels after chemotherapy. CONCLUSION: It is assumed that evidence of impaired T cell responses is somewhat definite. These observations suggest that proliferative responses to phytohemagglutinin, CD4+ T cell, natural killer cell activity defects are due to leukemia itself but others more likely are generalizable defects caused by chemotherapy. Further investigations, however, have suggested a persisting defect in IgA, proliferative reponses to phytohemagglutinin, and interleukln-2. Our observations also show that despite normal immunoglobulin levels, most of these children have nonprotective levels for common childhood bacterial or viral disease. These results support to the praxis to withdraw prophylactic antibiotics after discontinuation of intensive chemotherapy and to start the immunization. It is expect to try to use cytokine on treatment and to improve mortality and morbidity for children of acute leukemia also.

We performed a clinical observation on the 208 cases of infectious hepatitis who were cared at the pediatric department of Fatima Hospital from July, 1, 1970, to June, 30, 1977, and obtained the following results. 1. The ratio of infectious hepatitis to the total number of in-patients was 3.25 in average. 2. There was no significant difference in seasonal incidence except spring when the incidence was lower than the other seasons. 3. The age-group of 3~8 years old occupied 69% of the total cases and sex incidence revealed mali predominence with the ratio about 2:1. 4. The frequently observed clinical manifestations included ; Anorexia(71%)Nausea/Vomiting(65%), Tiredness(53%), Dark urine(59%), Abdominal pain(54%), Fever(45%), Jaundice(75%), Hepatomegaly(71%), Tenderness on upper adbomen(40%), and Palpable spleen(12.3%). 5. In the most of the cases the hematologic findings were with-in normal limit. 6. Bilirubinuria was observed in about 65% of the tested cases during the first 2 weeks of the illness and urinary urobilinogen was decreased during the second week of the illness. 7. In the majority of the cases the serum bilirubin reached peak during the second week of the illness and ranged 2~15mg%. And by the end of the 4th week illness, they returned to less than 2mg% in the 85%of the tested cases. 8. SGOT and SGPT reached peak during the first week of the illness and by the end of 4th week, they returned to less than 100 unit in the most the tested cases. And the values of SGOTwere higher than SGOT throughout the course of the illness. 9. The electrophoresis of the serum protein revealed as follow ; 1-globulin decreased slightly and -globulin in creased. 10. We experienced 30 cases (14.4%) of anicteric hepatitis. 11. ABHg was positive in 2(3.8%) of the 52 tested cases. 12. 10 of the 208 cases complicated hepatic coma and 10 of them expired and 3 of them dischared without clinical improvement.

Background:
Conventional radial forearm free flaps (RFFFs) are known to be safe, but can result in donor site complications. Based on our experiences with suprafascial and subfascial RFFFs, we evaluated the safety of flap survival and surgical outcomes.
Methods:
This was a retrospective study of head and neck reconstructions using RFFFs from 2006 to 2021. Thirty-two patients underwent procedures using either subfascial (group A) or suprafascial (group B) dissection for flap elevation. Data were collected on patient characteristics, flap size, and donor and recipient complications, and the two groups were compared.
Results:
Thirteen of the 32 patients were in group A and 19 were in group B. Group A included 10 men and three women, with a mean age of 56.15 years, and group B included 16 men and three women, with a mean age of 59.11 years. The mean defect areas were 42.83 cm² and 33.32 cm², and the mean flap sizes were 50.96 cm² and 44.54 cm² in groups A and B, respectively. There were 13 donor site complications: eight (61.5%) in group A and five (26.3%) in group B. Flexor tendon exposure occurred in three patients in group A and in none in group B. All flaps survived completely. A recipient site complication occurred in two patients (15.4%) in group A and three patients (15.8%) in group B.
Conclusions
Complications and flap survival were similar between the two groups. However, tendon exposure at the donor site was less prevalent in the suprafascial group, and the treatment period was shorter. Based on our data, suprafascial RFFF is a reliable and safe procedure for reconstruction of the head and neck.
