Taper corrosion has been widely reported to be problematic for modular total hip arthroplasty implants. A simple and systematic method to evaluate taper damage with sufficient resolution is needed. We introduce a semiquantitative grading system for modular femoral tapers to characterize taper corrosion damage.

Unlabelled: The aim of this study was to compare high-intensity interval exercise (HIIE) sessions prescribed on the basis of a maximal value (peak power output, PPO) and a submaximal value (lactate threshold, LT) derived from graded exercise tests (GXTs) in normoxia and hypoxia.

Methods: A total of ten males (aged 18-37) volunteered to participate in this study. The experimental protocol consisted of a familiarization procedure, two GXTs under normoxia (FiO = 0.

Previous investigators have suggested a role for generalized joint hypermobility (GJH) in the etiology of clubfoot deformity, while others have suggested its presence may influence treatment outcomes. We sought to determine if GJH was associated with the demographics, treatment, or propensity to relapse of patients whose clubfeet were managed using the Ponseti method. Fifty-seven patients with Ponseti-treated clubfeet comprised the cohort; median age 61 months (range, 38-111 months).

Primitive epidermis develops the nail apparatus. Nails have a strong and inflexible nail plate at the end of each digit. Very few genes responsible for causing nonsyndromic form of nail dysplasia have been reported.

Aims: After the initial correction of congenital talipes equinovarus (CTEV) using the Ponseti method, a subsequent dynamic deformity is often managed by transfer of the tendon of tibialis anterior (TATT) to the lateral cuneiform. Many surgeons believe the lateral cuneiform should be ossified before surgery is undertaken. This study quantifies the ossification process of the lateral cuneiform in children with CTEV between one and three years of age.

Relapse of cancer months or years after an apparently successful therapy is probably caused by cancer stem cells (CSCs) due to their intrinsic features like dormant periods, radiorefraction, and acquired multidrug resistance (MDR) phenotypes, among other mechanisms of cellular drug evasiveness. Thus, the lack of currently efficacious interventions remains a major problem in the treatment of malignancies, together with the inability of existing drugs to destroy specifically CSCs. Neuroblastomas per se are highly chemotherapy-refractory extracranial tumors in infants with very low survival rates.

The DNA binding modes and cleavage properties of novel dinuclear Ir(III) polypyridyl (pp) complexes [{(η(5)-C(5)Me(5))Ir(pp)}(2)(μ-B)](CF(3)SO(3))(4) depend on the lengths of their rigid bridging dipyridinyl ligands B. Mono-intercalation and strong DNA cleavage properties were observed for the dipyrido[2,3-a:2',3'-c]phenazine (dppz) complexes 1 (B = 4-[(E)-2-(4-pyridinyl)ethenyl]pyridine) and 3 (B = 4-(2-pyridin-4-ylethynyl)pyridine), whose intracationic Ir···Ir' distances are about 13.1 and 13.

Half-sandwich organorhodium(III) complexes and their trichloridorhodium(III) counterparts are potent anticancer agents that enhance the formation of reactive oxygen species and invoke a strong induction of apoptosis in leukemia cells. The antiproliferative activity towards human MCF-7 and HT-29 adenocarcinoma cells of novel nonintercalating complexes containing the 5-substituted phenanthroline ligands 5,6-dimethylphenanthroline, 5-chlorophenanthroline, and 5-nitrophenanthroline (phen*) increases dramatically in the order [(η(5)-C(5)Me(5))IrCl(phen*)](CF(3)SO(3)) < [(η(5)-C(5)Me(5))RhCl(phen*)](CF(3)SO(3)) < mer-[RhCl(3)(DMSO)(phen*)] (DMSO is dimethyl sulfoxide). Improved activity was also achieved by attaching a cell-penetrating peptide to the dipyrido[3,2-a:2',3'-c]phenazine (dppz) ligand of an organorhodium(III) complex.

Facial cellulitis in the pediatric hospital population can be classified as odontogenic and nonodontogenic. Emergency departments welcome timely diagnosis from consultants as cellulitis is associated with significant morbidity in children. The purpose of this retrospective study is to assist pediatric dentists in recognizing differences between odontogenic and nonodontogenic facial cellulitis and to determine whether odontogenic infections make up a major portion of facial swellings seen upon admission to the hospital.

Because the term 'dermoid' is frequently used in the literature, some authors believe that this term should be used for all congenital cysts of the floor of the mouth. Three subclasses of congenital floor of the mouth cysts are described in the literature: (1) epidermoid (simple) cysts, (2) dermoid (complex) cysts and (3) teratoid (complex) cysts. The teratoid cyst is the least common.

High frequency jet ventilation (HFJV) has been used recently as an alternative to conventional endotracheal intubation in bronchoscopy and laryngoscopy procedure. The objective of this study was to define the applicability of the system to dental procedures performed on healthy and medically compromised patients. A total of seventeen pediatric patients ranging in age from twenty-eight months to fourteen years were included.

Intrusion of the head of the condyle into the middle cranial fossa is a rare but highly significant result of trauma to the mandible. Various treatment modalities for this type of injury have been reported in the literature. This case report concerns the intrusion of the left mandibular condyle into the middle cranial fossa in an 11-year-old girl.

Cyclosporin A, since its introduction, has drastically reduced the morbidity and mortality rates associated with organ transplants. One side-effect of CSA is gingival hyperplasia. This study investigated the effects of CSA given in conjunction with a low dose of steroids on the gingival status of pediatric patients following liver transplantation.

The emergency room records of 1,456 children who were treated at Children's Hospital of Pittsburgh with any oral complaint, during a single calendar year, were reviewed with the data entered into a computer. The data were tabulated and statistically analyzed. Trauma (676 visits) was responsible for 46 percent of the total visits, with boys representing a significantly higher percentage of trauma visits than girls (440 vs 236).
