Isolated acromial fracture is not common and it frequently accompanies fractures to the coracoid process and glenoid bone and also injuries to the acromioclavicular joint. Furthermore, most of these combined acromial fractures have minimal displacement, which needs no additional treatment other than protection for a certain period of time. We have experienced a case of isolated fracture of the posterolateral angle of the acromion, which we reduced and fixated using K-wire and cannulated screws. We report on the technical aspects and clinical results of this reduction and fixation, along with a review of the literature.

PURPOSE: This study investigates the effectiveness of FK-506, a new immunosuppressive agent for in preventing the rejection of limb allo-transplants in rats. MATERIALS AND METHODS: Inbred strain Lewis (RT1l) were used as donors and Brown Norway (RT1n) as recipients for limb allotransplan-tation. The experimental animals were divided into four groups; group I: untreated allografts, group II: allografts receiving FK-506 1mg/kg/day for 5-12 days (n=6), group III: 2 mg/kg/day for 15 days (n=6), group IV: single dose of 10 mg/kg (n=3), immediately. Rejection signs, mean survival time of limbs and histologic analysis (by the muscle grading system of Buttemeyer et al.) were evaluated. RESULTS: The mean survival time in group I was 3.5 +/-1.04 days, in group II 7.17 +/-3.43 days, in group III 25.5 +/-12.01 days and in group IV 16.33 +/-8.08 days. FK-506 prolonged the survival time of limbs significantly in a dose-dependent manner. Histologic examination revealed that group II was grade II (n=2) and grade III (n=1); group III was grade I (n=2); and group IV was grade I (n=1) and grade II (n=1). CONCLUSION: These results demonstrate the unique effects of FK-506 upon preventing graft rejection and prolonging limb survival allo-grafts in rats.

Journal of Korean Academy of Oral Health 2024;48(3):155-165
Objective:
This study aimed to review domestic and international literature on oral health interven-tions for pregnant women and provide basic data for the development of oral health intervention programs.
Methods:
We used domestic and international search databases, such as Medline, Embase, Re-search Information Sharing Service, Science On, Korea Citation Index, and DBpia. Among papers published between 2003 and 2023, 22 met the selection criteria by combining “pregnant women,” “oral hygiene,” and “oral health.”
Results:
Since 2007, foreign literature has steadily increased; however, domestic literature has decreased. Overseas research designs were mostly randomized control trials, whereas domestic designs were mostly non-equivalent control group pretest-posttest. The intervention methods in-cluded three preventive programs, five specialized oral care programs, and 14 oral health education programs.
Conclusions
In-depth research should be conducted to increase the understanding and interest of pregnant women. Systematic intervention programs that consider the effectiveness and sus-tainability of intervention methods should be developed, and policy support should be provided to strengthen the importance of oral health education by experts and institutional improvements.

A recent study claimed that botulinum toxin A (BTX-A) injection into the calf muscle of cerebral palsy (CP) children did not change the intrinsic stiffness. Contrary to this recent report, in our case, decreased muscle spasticity, which was measured using a modified Ashworth scale, and increased Gross Motor Function Measure score were demonstrated at 4 weeks after intensive rehabilitation treatment (IRT) with BTX-A injection to the medial gastrocnemius muscle in a child with spastic CP. Additionally, we indentified decreased muscle stiffness which was demonstrated by a decrease in the color-coded scale and shear velocity, and an increase in the strain ratio using dynamic sonoelastography.

BACKGROUND: Radiation therapy is widely employed in the treatment of head and neck cancer. Adverse effects of therapeutic irradiation include delayed bone healing after dental extraction or impaired bone regeneration at the irradiated bony defect. Development of a reliable experimental model may be beneficial to study tissue regeneration in the irradiated field. The current study aimed to develop a relevant animal model of post-radiation cranial bone defect. METHODS: A lead shielding block was designed for selective external irradiation of the mouse calvaria. Critical-size calvarial defect was created 2 weeks after the irradiation. The defect was filled with a collagen scaffold, with or without incorporation of bone morphogenetic protein 2 (BMP-2) (1 μg/ml). The non-irradiated mice treated with or without BMP-2-included scaffold served as control. Four weeks after the surgery, the specimens were harvested and the degree of bone formation was evaluated by histological and radiographical examinations. RESULTS: BMP-2-treated scaffold yielded significant bone regeneration in the mice calvarial defects. However, a single fraction of external irradiation was observed to eliminate the bone regeneration capacity of the BMP-2-incorporated scaffold without influencing the survival of the animals. CONCLUSION: The current study established an efficient model for post-radiation cranial bone regeneration and can be applied for evaluating the robust bone formation system using various chemokines or agents in unfavorable, demanding radiation-related bone defect models.

It has long been thought that in individuals with congenitally narrower spinal canals, the risk of spinal cord injury might be increased. The purpose of the present study was to quantitatively assess spinal cord pressures in cadaveric human cervical spines with narrow and wide canals, and with normal and degenerative columns. Twelve human cadaveric cervical spine preparations were evaluated on the basis of their level of degeneration and canal size. A drop mass assembly was constructed with different combinations of masses to produce 24 possible drop combinations for each spine preparation. These resulted in input energies from 100 to 1000 'gram-centimeters'. Cadaver cervical spine was instrumented with a collagen encased artificial spinal cord and seven sensor transducer arrays recorded pressures on the cord during the impact event. The results indicated that depending on the extent and and level of degeneration, degenerated spinal columns produced distinctly different patterns of cord pressure. Normal spinal columns produced consistent patterns of high pressures under the impact site, but this decreased caudally and cranially. In specimens with narrow spinal canals, cord pressures under the impact site were significantly higher than in specimens with wide canals. For the higher drop energies(800 and 1000 'g-cm') the disparity between narrow and wide canal specimens increased. This implies that for the same inpt drop energy, the propensity for spinal cord injury is higher for narrower spinal canals than for those which are wider.

The inhalation of naphthalene used as deodorant balls in public toilets could be an important cancer risk factor. The atmospheric concentration of naphthalene in public toilets (C(in)) was estimated both by a polyurethane foam passive air sampler (PUF-PAS) deployed in nine public toilets in Seoul, Korea and by a steady-state indoor air quality model, including emission estimation using Monte-Carlo simulation. Based on the estimated C(in), cancer risk was also assessed for cleaning workers and the general population. The steady-state C(in) estimated using the estimated emission rate, which assumed that air exchange was the only process by which naphthalene was removed, was much greater than the C(in) value measured using PUF-PAS in nine public toilets, implying the importance of other removal processes, such as sorption to walls and the garments of visitors, as well as decreased emission rate owing to wetting of the naphthalene ball surface. The 95 percentile values of cancer risk for workers based on the estimation by PUF-PAS was 1.6×10â»â¶, whereas those for the general public were lower than 1×10â»â¶. The results suggested that naphthalene deodorant balls in public toilets may be an important cancer risk factor especially for the cleaning workers.

The results suggested that naphthalene deodorant balls in public toilets may be an important cancer risk factor especially for the cleaning workers.
