An unusual bifid first metacarpal  [cached]
Kumar Suresh
Indian Journal of Orthopaedics , 2010,
Abstract: Bifid first metacarpal is a common congenital anomaly. Here, we report an unusual case of bifid first metacarpal in a 13-year-old girl who presented with swan neck deformity of left thumb, a bony prominence on ulnar aspect of left thumb in the first web space and a bifid first metacarpal lacking its own epiphysis. The patient underwent surgery, resulting in complete functional recovery as well as cosmetic improvement of the left thumb.

Abstract: the bifid condylar process is a rare alteration that is usually diagnosed as an incidental finding in a panoramic radiograph. the etiology of bifid condylar process is unknown, although the most tenable theory is that of traumatic origin. a 46-year-old woman was referred to our dental department with a complaint of pain and clicking on her temporomandibular joints. a panoramic radiograph showed bilateral bifid condyles described with bifid condylar process varies from case to case, however in most cases are asymptomatic. the most common and predominant symptoms are temporomandibular joints sounds. the diagnosis of bifid condylar process is based on its radiographic appearance. some researchers have indicated the necessity of imaging the anomaly by a second imaging method obtained in a different plane, in addition to orthopantomograph, and they have employed different techniques such as ct and magnetic resonance imaging. the bifid condylar process, and particularly the bilateral bifid condylar process, is a rare finding, the etiology of which remains uncertain. it is predominately an asymptomatic condition, discovered by chance on routine radiographic survey. the diagnosis is based on the radiographic manifestations and the treatment is usually conservative.
Bigeminy and the bifid papillary muscle
James Ker
Cardiovascular Ultrasound , 2010, DOI: 10.1186/1476-7120-8-13
Abstract: Recently two reports have appeared where the base of the posterior papillary muscle was identified as the source of frequent premature ventricular complexes. In some of these patients these frequent premature ventricular complexes have led to left ventricular dysfunction.In this report a newly discovered structural variant of the anterior papillary muscle is described--the bifid papillary muscle. Furthermore, it is proposed that this bifid papillary muscle is the source of frequent ventricular premature complexes, presenting as bigeminy in a patient with normal left ventricular function.In recent years various anomalies of the left ventricular papillary muscles have been observed [1]. These include: solitary hypertrophy [2] (as a variant of hypertrophic cardiomyopathy), accessory papillary muscles [1], inverted papillary muscles giving a "mirror" appearance [3], and an octopus-shaped variant, leading to mid-ventricular obstruction [4].Interestingly, many of these papillary muscle variants have been linked to electrocardiographic aberrations [1,2,5]: These include: prominent U-waves in the inferior leads with an accessory papillary muscle [1], notching of the QRS-complex with ST-segment elevation and a prominent, positive U-wave, all in lead V4 with solitary hypertrophy of the anterolateral papillary muscle [2] and inferior J-waves with an accessory papillary muscle [5].In this report, a new structural variant of the anterolateral papillary muscle is described--the bifid papillary muscle. In addition the patient had frequent premature ventricular complexes, presenting with pulsus bigeminy. It is proposed that the bifid papillary muscle is a newly discovered entity causing bigeminy.A case report is presented depicting a new variant of the anterolateral papillary muscle--the bifid papillary muscle. Furthermore, there is a growing number of reports in the literature demonstrating various electrocardiographic aberrations caused by the papillary muscles and it's variants.
Beware the bifid rib!
S Scheepers, S Andronikou
South African Journal of Radiology , 2010,
Abstract: A 4-year-old girl was referred to Tygerberg Academic Hospital with a long-standing history of an asymptomatic anterior chest wall ‘lump’. On physical examination, a bony mass was palpated in relation to the anterior aspect of the left 4th rib. Plain radiography demonstrated anterior widening of the left 4th rib (Fig. 1). Fearing a sinister cause, a multidetector computed tomography (MDCT) examination of the chest, with 3D reconstruction and volume rendering, was performed (Fig. 2). A congenital bifid left 4th rib was demonstrated.
Bifid Condylar Process: Cases Report
Fuentes Fernández,Ramón; Flores Flores,Homero; Silva Mella,Héctor; Flores Lillo,Tania;
International Journal of Morphology , 2009, DOI: 10.4067/S0717-95022009000200038
Abstract: the bifid condylar process is a rare anomaly. most of the known cases are radiographic findings, mainly in ortopantomography and nuclear magnetic resonance. the condition is usually asymptomatic, while in some cases are associated with ankylosis of the temporomandibular joint. it is reported that the presence of bifid condylar process is not determined by age and gender, but the findings are among the ages of 3 to 67 years, with the average age of 35 years. the present report presents two cases of patients with abnormalities of condylar process detectable through radiographic examination.

Abstract: Este documento tiene como objeto aplicar los conceptos sobre la estimación de parámetros para una planta descrita por un modelo en función de transferencia, que luego será aplicada a un sistema de control adaptativo. Se realiza una simulación de los estimadores paralelo y serie-parelelo, con el fin de examinar los efectos producidos por la naturaleza de la entrada al sistema, la ganancia adaptativa y las perturbaciones debidas al ruido.
Journal of Research in Medical Sciences , 2000,
Abstract: Introduction. Bifid uvulae is a silent abnormality in children which can almost exist without clinical problems but in some instances it is accompanied with either sub mucosal cleft and hypernasality. Methods. In a cross sectional study, the examiners carried out oral examination of 3000 children and the structure of the uvulae was evaluated as normal or bifid. Results. The prevalence of bifid uvula was 0.8 percent (25 children). Positive family history, familial marriage and positive teratogen exposure history were detected in four, twenty and eight percent of bifid uvalae cases, respectively. Discussion. Bifid uvulue prevalence in European and American children was reported more than our findings. This gap may be due to different cultural habits as well as environmental factors.

International Journal of Morphology , 2011, DOI: 10.4067/S0717-95022011000300043
Abstract: the bifid mandibular condyle is an exceedingly rare anomaly, frequently diagnosed as an incidental finding in a panoramic radiograph. its etiology and pathogenesis are unknown, though the most acceptable theory suggests that trauma is at the origin of the condition. this article reports a new case of bilateral bifid condyle in a 21-year-old female with history of trauma in childhood.

Indian Journal of Dental Research , 2009,
Abstract: Bifid mandibular canal is a rare anatomical variation that can be of considerable interest to a dentist. This condition can lead to complications when performing mandibular anesthesia or during surgery of the lower third molar, orthognatic or reconstructive mandibular surgery, or placement of dental implants and prosthesis; bleeding and traumatic neuroma are possible complications. Therefore, awareness of this condition is important. We report two cases of bilateral bifid mandibular canal: one in a 22-year-old male and the other in a 24-year-old female.
