The acetabular angles were measured in 2 groups of selected 100 infants and children each, of whom one group aged 14 months and younger and the other group aged 15 months of 5 yrs. and who were proved to be normal by all the physical examination and whose acetabular angles were below 40 according to Coleman's diagnostic criteria. The measurements were broken down into right and left, and male and female because of the known difference in the incidence of CDH in 2 members of each of these paired categories and analysed statistically. The following statistic significances resulted: l. All the measured normal acetabular angles vary between 10 and 31 degrees. 2. The acetabular angles decrease after weight bearing by the statistical significant difference between 0-14 mo. group and 15 mo-5yr. group. The angles are 22,61±3,47 (M±S,D) and 18.68±3.64 (M±S.D) respectively. 3. The acetabular angles of female of 15mo.-5yr. group are higher than male by the statistical significant difference. The angles are 17.77±3.54 (M±S.D) and 20.18±3.29 (M±S.D) respectively. 4. Statistical significant differences were absent between right and left.

Mucormycosis is an infectious disease caused by fungi of the order Mucorales. Almost all patients have a serious uriderlying condition such as diabetes mallitus, imrnunosuppression, starvation, burn, but a few cais have been reported in previously heilthy subjects. In order to successfully treat this infection, diagnosis must be prompt and acior. panied by aggressive debridement and parenteral administration of amphotericin B. We report a case of primary cutaneous mucormycosis in 58-year-old man. The lesion was a well-circumscribed erythematous plaque with central necrcis Histopathologically, a biopsy revealed broad, nonsptate with branches occuring at right anghles.

We observed three patients who showed widespread macular ashy-colored eruptions. They fit clinically and histopathologically with the typical erythema dyschromicum perstans (ashy dermatosis). Erythoma dyschromicum perstans is a peculiar pigmented condition of unknown etiology characterized by persistent ashy-gray colored macule, refractory to any modality. All of them have similar skin lesions which are multiple, variable sized oval-shaped, ash-colored macular eruption on the trunk and extremities. Histologic findings of 2 patients reveal the characteristic feature of focal hydropic degeneration of the basal cell layer of the epidermis, perivascular infiltrates of lymphocytes and histiocytes and melanin-laden macrophages in the corium, however, merely pigmentary incontinence into the corium in 1 patient. Literatures are briefly reviewed.

We analyzed the factors of importance for nonunion in series of 91 open fractures of tibial diaphysis which were treated with external fixation. Factors analyzed included, age and sex of the patients, the mechanism of injury, the amount of soft tissue damage, the grade of comminution, the level at which the tibia was fractured, the presence of an intact fibula, the presence of the multiple injuries, the type of the external fixation used(AO external fixator, EXTOR; monotube external fixator, Ilizarov), and the need to supplement the stability of the reduction. We found that the amount of soft tissue damage and comminution of the fracture played a role in the development of the nonunion.

Dementia and Neurocognitive Disorders 2021;20(4):70-79
Background:
and Purpose: Interpreting the Rey complex figure (RCF) requires a standard RCF scoring system and clinical decision by clinicians. The interpretation of RCF using clinical decision by clinicians might not be accurate in the diagnosing of mild cognitive impairment (MCI) or dementia patients in comparison with the RCF scoring system. For this reason, a machine-learning algorithm was used to demonstrate that scoring RCF using clinical decision is not as accurate as of the RCF scoring system in predicting MCI or mild dementia patients from normal subjects.
Methods:
The RCF dataset consisted of 2,232 subjects with formal neuropsychological assessments. The RCF dataset was classified into 2 datasets. The first dataset was to compare normal vs. abnormal and the second dataset was to compare normal vs. MCI vs. mild dementia. Models were trained using a convolutional neural network for machine learning.Receiver operating characteristic curves were used to compare the sensitivity, specificity, and area under the curve (AUC) of models.
Results:
The trained model's accuracy for predicting cognitive states was 96% with the first dataset (normal vs. abnormal) and 88% with the second dataset (normal vs. MCI vs. mild dementia). The model had a sensitivity of 85% for detecting abnormal with an AUC of 0.847 with the first dataset. It had a sensitivity of 78% for detecting MCI or mild dementia with an AUC of 0.778 with the second dataset.
Conclusions
Based on this study, the RCF scoring system has the potential to present more accurate criteria than the clinical decision for distinguishing cognitive impairment among patients.

Authors analysed 36 cases(33 patients) of Peroneal Buoy Flap to investigate branching pattern, course, length of vascular pedicle, and perforating level of the perforating cutaneous branches from Oct. 1985 to July 1988. The results were as follows. 1. The perforating cutaneous branchea were classified into four types, the Straight Branch (18 cases), the Proximal Oblique Branch (8 cases), the Branch from Muscular Artery (8 cases), the Distal Oblique Branch(2 cases) respectively. The most common patten was Straight Branch. 2. There were 3 pathways of these branches, the most common one passed between the Soleus and Peroneus muscles(23 cases, 64%), and second one passed through the snterior part of Soleus muscle(8 cases, 22%), the third one passed through the posterior part of Peroneus muscle(5 cases, 14%). 3. The length of vascular pedicle in Buoy Flap was variable from 3cm to 15cm, but 27 cases(75%) were distributed between 4cm and 6cm. 4. The perforating level of branches were 6.3cm in average from Fibular Neck, 88% of them were distributed within 10cm. 5. Peroneal Buoy Flap in possible to reconstruct both seperated bone and skin defect in some distance by One-Stage Operation.
