Conservative Treatment of Complicated Oblique Crown-root Fractures of Molars: A Report of Five Representative Cases

The five cases presented here describe a conservative treatment procedure for complicated crown-root fractures of molars with extensive loss of tooth structure. After the mobile crown-root fragments were extracted, the remaining crowns were restored at the juxtagingival level. The follow-up time ranged from two years, seven months, to four years. At the follow-up examinations, all of the teeth were asymptomatic and had healthy clinical appearances. There was no evidence of pockets related to fractures. The results of these cases show that complete periodontal healing is possible with conservative treatment of complicated crown-root fracture of molars.

Overexpression of Uromodulin-like1 accelerates follicle depletion and subsequent ovarian degeneration

Murine Uromodulin-like 1 (Umodl1) encodes Ca²⁺-dependent EGF-like membrane-bound proteins. This study presents its novel expression in the immune and female reproductive systems. Upon stimulation by CD3/CD28 antibodies, Umodl1 showed a prompt and robust response in the proliferating CD4⁺ T cells, suggesting its implication in immune defense against pathogens. In ovary, Umodl1 is regulated by gonadotropins. Mice carrying extra copies of functional Umodl1 were generated by BAC transgenesis. Defects in the female reproductive system became evident from 4 months of age, manifested by reduced or diminished fertility. Histology revealed that the ovaries contained very few discernible follicles in the cortical region, and were devoid of distinguishable corpus lutea (CL). Among the multilayered preantral follicles, elevated apoptosis was observed in both the oocytes and surrounding granulosa cells (GCs). Furthermore, a high level of PPARγ indicated an abnormal adipogenesis in the mutant ovaries, which resulted in the conversion of GCs into adipocytes. By 6 months of age, all mutant mice became anovulatory. Ovarian tissues including CL, follicles of various stages and associated stromal cells were degenerated. Altered expression of AMH, follicle-stimulating hormone and other ovary-specific marker genes such as Gdf-9, Rnf35, NOHLH and Gcx-1 further demonstrated that the molecular properties of the mutant ovaries have been severely disturbed. This work presents a novel animal model for investigating the pathogenesis of premature ovarian failure or early ovarian ageing.

A Rare Midfoot Injury Pattern: Navicular—Cuneiform and Calcaneal—Cuboid Fracture—Dislocation

A rare midfoot injury pattern of navicular—cuneiform and calcaneal—cuboid fracture—dislocation is presented with two typical cases and a systematic review of the literature. This injury usually occurs as a result of high-energy crushing trauma and most often causes plantarly directed dislocation of the midfoot. Initial diagnosis includes a thorough physical examination and adequate radiological imaging, comprising anteroposterior, oblique and lateral X-radiography and computed tomography with three-dimensional reconstruction. Care should be taken to determine any injury to adjacent midfoot joints, in particular the Lisfranc joint. Intrasurgical protection of soft tissue is essential. Open reduction using two parallel incisions with minifragment plate fixation is recommended in more comminuted injuries. The navicular—cuneiform and calcaneal—cuboid joints play important roles in maintaining the arch of the foot and in weight-bearing during locomotion. Without proper therapy in the immediate post-traumatic phase, the long-term results are generally unsatisfactory.
