Clinics review is made on 61 cases of rectal prolapse treated at Chonnam University Hospital from January, 1956 to December, 1964. The ratio of male to female was about 3 to 1, 46(75.4%) being male and 15(24.6%) female. In the majority, age ranged from 21 to 40 years (45.9%). Chronic diarrhea constipation and respiratory disease were implicated as the most principal precipitating factor and cases of unknown causes were 25. Duration of symptoms was as follows: 29 patients were within 1 year and 14 were over 5 years. All of them were suffered from anal protruding mass after defecation and frequent complaints were anal bleeding and perineal pain. Mild cases were treated conservatively and 32 cases were treated surgically. Recurrence developed in seven of those treated surgically.

Electro-spun silk web has attracted attention for biomedical applications because of its excellent bio-compatibility and facile fabrication method. Because biomedical applications require various performances of silk web, many studies have been conducted on the effect of the variables associated with their preparation on the structure and properties of silk web. In the present study, the effect of residual sericin content on the morphology, structural characteristics, and properties of electrospun regenerated silk web was examined. The regenerated silk without sericin (i.e., silk with 100 wt% fibroin) did not show good electro-spinnability. However, the electro-spinnability improved remarkably above a sericin content of 0.6 wt%. The crystallinity index of the electro-spun silk increased at 0.6 wt% sericin content and decreased above 8.2 wt% sericin. The mechanical properties of the electro-spun silk webs showed a similar trend as their crystallinity indices. The breaking strength and elongation improved significantly at 0.6 wt% sericin content and both parameters gradually decreased above this value. The thermal stability of the silk web decreased slightly upon increasing the sericin content.

Purpose: To investigate the relationship between maturity of a cataract and the pattern of pain during cataract surgery under topical anesthesia. Methods: This study comprised 105 eyes of 75 patients undergoing cataract surgery under topical anesthesia. The pain scale during each procedure was scored from 0 to 10 in numeric pattern and analyzed with the cataract maturation degree. Additionally, pain scores were compared between the first and the second eye in 14 consecutive cataract patients. Results: The average pain score during cataract surgery was 0.86 ± 0.55, and the average maximal pain experience score during surgery was 3.24 ± 1.51, which was generally tolerable. Phacoemulsification was marked as the most painful step among cataract surgery procedures (1.93 ± 1.64), followed by the removal of the surgical draping (1.31 ± 1.53) and the initial instillation of topical anesthetic (1.29 ± 1.28). Progression and cataract typing was not related to pain either during overall cataract surgery procedures or when separately analyzed during procedures. There was no significant difference between the pain scores reported in consecutive cataract surgeries. However, in subjective comparison of consecutive surgeries, more patients reported greater pain in the second operation. Conclusions: The pain score reported during cataract surgery procedures under topical anesthesia was within a generally tolerable range. Cataract progression does not appear to be related to pain during the operation. In consecutive surgeries, pain measured by a numerical scale and subjective pain experience showed different results.

A 3-year-old girl presented with congenital orbital fibrosis. We performed molecular genetic analysis by whole exome and mitochondrialgenome sequencing. No pathologic mutation was identified in the present case. To our best knowledge, this study presents the first report on the findings of mutational analysis of a patient with congenital orbital fibrosis.
