The new trial to apply the closed I-M nailing for 23 cases of long bone fracture has been used our department, loss of hematoma, further damage to periosteum and soft tissue were prevented; the risk of infection was reduced; and the early functional use of extremities without additional superflous external fixation could be made. The results obtained were as follows; 1. There was no case of non-union or other complication. 2. The average bone union rate was 26.1 weeks in femur, 22 weeks in tibia, or 11.5 weeks in forearm. 3. The advantages is simple method and be able to do early ambulation without following muscular atrophy or ankylosis. 4. The patients were satisfactory about cosmetic problem after operation. 5. The merits of this operation were the short hospitalization and early adaptation of social activity. 6. In conclusion, closed I-M nailing is method of choice for long bone shaft fracture when internal fixation is indicated and our operative is useful and simple.

We reviewed two cases of keratosis punctata palmaris et plantaris(KPP) and the scanning electron microscopic findings(SEM). The skin lesions of KPP are multiple, hyperkeratotic on the palms and soles with central pitting. There was no subjective symptoms. The histologic findigs revea,l marked hyperkeratosis, hypergranulosis, and acanthosis with depression of the underlying malpighian layers. The SEM findings reveal one hyperkeratoic plug on punctate lesion(case I ) and three hyperkeratotic plugs on depression of the malpighian layer(case ll ).

A case of low-grade endometrial stromal sarcoma resembling ovarian sex-cord tumor in the uterus of a 43-year-old woman is described. This tumor belongs to the group II category of uterine tumors resembling ovarian sex-cord tumor described by Clement and Scully, and the epithelial-like elements show prominent smooth muscle differentiation, proved by immunoreactivity for desmin and actin. The patient did not receive any adjuvant therapy; she is alive and well without recurrence 8 months postoperatively.

Background: Hypoalbuminemia reflects several pathological conditions, including nutritional deficiencies and chronic inflammation. However, its relationship with short-term and long-term mortality in patients undergoing continuous renal replacement therapy (CRRT) remains unclear. The present study aimed to assess the effect of hypoalbuminemia on mortality in a large cohort of patients undergoing CRRT. Methods: The study retrospectively reviewed 1,581 patients who underwent CRRT for the treatment of acute kidney injury from 2010 to 2016. The patients were categorized by tertiles of serum albumin levels at CRRT initiation. The odds ratios and hazard ratios for the risk of all-cause mortality were calculated before and after adjustment for multiple covariates. Results: The mean albumin level was 2.7 ± 0.6 g/dL at CRRT initiation. During a median follow-up period of 14 days (maximum, 4 years), 1,040 patients (65.8%) died. The risk of overall mortality was higher in the first tertile group than in the third tertile group (hazard ratio, 1.9 [1.63-2.21]). When the mortality rate was stratified by timeframe, the risk was steadily higher in the first tertile group than in the third tertile group (odds ratios: 3.0 [2.34-3.87] for 2-week mortality, 2.7 [2.12-3.52] for 1-month mortality, 2.7 [2.08-3.53] for 6-month mortality, and 2.8 [2.11- 3.62] for 1-year mortality). Additionally, the rates of intensive care unit mortality and in-hospital mortality were higher in the first tertile group than in the third tertile group. Conclusion The initial hypoalbuminemia was independently associated with short-term and long-term mortality in patients undergoing CRRT. Thus, the serum albumin level should be monitored during CRRT.

This study was carried out to reveal the epidemiologic characteristics of psoriasis in Korea. Seventeen university hospitals were engaged in this study, and the results were as follows : 1. The number of psoriasis patients during the 10 years from January 1977 to March 1987 was 1.05% of all the outpatients; the male to female-ratio was 1.08:1. 2. In the prospective study, the number of psoriasis patients was 2.3% of all the outpatients in 1987, 2.8% of all the outpatients in 1988 and the male to female ratio was 1.26:1. 3. The most prevalent age of onset was 20-29 years ; 81.1% were living in urban areas; and a family history was obtainable in 19.8% with parents holding the highest rank of 7.8%. 4. The most frequent duration of disease activity was under 5 years in 63.3%; the most common age for the worst condition was 20-29 yrs. The most common area size of skin involvement at the peak of the worst condition was less than 10%. 5. The most common initiating skin lesion began on the scalp in 20.2%, on the nail in 17.2%, pruritus in 63.0% with joint symptoms in 10.8%, and Koebner phenomena in 50.6%. 6. Emotional stress was the most common aggravating factor in 34.4%. The method of treatment that attained the best result was the combination therapy of oral medication and a topical agent. The best treatment modality was said to be the application of ointment with p.o.medication by as many as 28.4% of patients who took the leading rank. Photo-chemotherapy, effective with few complications, was not used much as it was not well-known in Korea until after 1980. Most people had an accurate knowledge of psoriasis.

This study investigates the potential of cone-beam computed tomography (CBCT)-generated cephalograms as a replacement for conventional lateral cephalograms (LCs) in children and adolescents. This retrospective study included 60 individuals, equally divided into permanent and mixed dentition groups. Both groups underwent conventional LCs and CBCT scans on the same day. LCs were then derived from CBCT scans. The same examiner performed digital measurements twice, with a week’s interval, identifying landmarks and obtaining 7 angular and 5 linear measurements. In the permanent dentition group, significant differences were observed between the two imaging modalities for 6 angular and 2 linear measurements. In the mixed dentition group, significant differences were observed for 3 angular and 2 linear measurements. However, none of these differences exceeded the clinically acceptable limit of 2.0º or 2.0 mm. No significant differences in any measurement were found between the two groups (p < 0.05). CBCT-generated LCs demonstrated comparable results with good reliability in both dentition groups, suggesting their potential as suitable alternatives for children and adolescents who require CBCT for clinical purposes.

A 36-year-old female patient with aplastic anemia developed massive hemoptysis and was placed on ventilator support. However, airway obstruction by blood clots triggered desaturation and ventilator malfunction. Manual ventilation was initiated to improve oxy-genation, and emergency flexible bronchoscopy was performed to clear the airway. Nevertheless, the patient developed extensive subcutaneous emphysema, pneumothorax, and pneumomediastinum.
