DYT1 mutation in French families with idiopathic torsion dystonia. (1/379)
A GAG deletion at position 946 in DYT1, one of the genes responsible for autosomal dominant idiopathic torsion dystonia (ITD), has recently been identified. We tested 24 families and six isolated cases with ITD and found 14 individuals from six French families who carried this mutation, indicating that 20% of the affected families carried the DYT1 mutation. Age at onset was always before 20 years (mean, 9+/-4 years). Interestingly, the site of onset was the upper limb in all but one patient. Dystonia was generalized in seven patients and remained focal or segmental in three patients. The absence of common haplotypes among DYT1 families suggests that at least six independent founder mutations have occurred. In addition, one Ashkenazi Jewish family carried the common haplotype described previously in Ashkenazi Jewish patients, but it was absent in the other family. Moreover, the dystonia remained focal in the latter family when compared with the usual generalized phenotype in patients with the common Ashkenazi Jewish haplotype. This indicates that there are at least two founder mutations in this population. (+info)Acute systematic and variable postural adaptations induced by an orthopaedic shoe lift in control subjects. (2/379)
A small leg length inequality, either true or functional, can be implicated in the pathogenesis of numerous spinal disorders. The correction of a leg length inequality with the goal of treating a spinal pathology is often achieved with the use of a shoe lift. Little research has focused on the impact of this correction on the three-dimensional (3D) postural organisation. The goal of this study is to quantify in control subjects the 3D postural changes to the pelvis, trunk, scapular belt and head, induced by a shoe lift. The postural geometry of 20 female subjects (X = 22, sigma = 1.2) was evaluated using a motion analysis system for three randomised conditions: control, and right and left shoe lift. Acute postural adaptations were noted for all subjects, principally manifested through the tilt of the pelvis, asymmetric version of the left and right iliac bones, and a lateral shift of the pelvis and scapular belt. The difference in the version of the right and left iliac bones was positively associated with the pelvic tilt. Postural adaptations were noted to vary between subjects for rotation and postero-anterior shift of the pelvis and scapular belt. No notable differences between conditions were noted in the estimation of kyphosis and lordosis. The observed systematic and variable postural adaptations noted in the presence of a shoe lift reflects the unique constraints of the musculoskeletal system. This suggests that the global impact of a shoe lift on a patient's posture should also be considered during treatment. This study provides a basis for comparison of future research involving pathological populations. (+info)Three-dimensional eye-head coordination during gaze saccades in the primate. (3/379)
The purpose of this investigation was to describe the neural constraints on three-dimensional (3-D) orientations of the eye in space (Es), head in space (Hs), and eye in head (Eh) during visual fixations in the monkey and the control strategies used to implement these constraints during head-free gaze saccades. Dual scleral search coil signals were used to compute 3-D orientation quaternions, two-dimensional (2-D) direction vectors, and 3-D angular velocity vectors for both the eye and head in three monkeys during the following visual tasks: radial to/from center, repetitive horizontal, nonrepetitive oblique, random (wide 2-D range), and random with pin-hole goggles. Although 2-D gaze direction (of Es) was controlled more tightly than the contributing 2-D Hs and Eh components, the torsional standard deviation of Es was greater (mean 3.55 degrees ) than Hs (3.10 degrees ), which in turn was greater than Eh (1.87 degrees ) during random fixations. Thus the 3-D Es range appeared to be the byproduct of Hs and Eh constraints, resulting in a pseudoplanar Es range that was twisted (in orthogonal coordinates) like the zero torsion range of Fick coordinates. The Hs fixation range was similarly Fick-like, whereas the Eh fixation range was quasiplanar. The latter Eh range was maintained through exquisite saccade/slow phase coordination, i.e., during each head movement, multiple anticipatory saccades drove the eye torsionally out of the planar range such that subsequent slow phases drove the eye back toward the fixation range. The Fick-like Hs constraint was maintained by the following strategies: first, during purely vertical/horizontal movements, the head rotated about constantly oriented axes that closely resembled physical Fick gimbals, i.e., about head-fixed horizontal axes and space-fixed vertical axes, respectively (although in 1 animal, the latter constraint was relaxed during repetitive horizontal movements, allowing for trajectory optimization). However, during large oblique movements, head orientation made transient but dramatic departures from the zero-torsion Fick surface, taking the shortest path between two torsionally eccentric fixation points on the surface. Moreover, in the pin-hole goggle task, the head-orientation range flattened significantly, suggesting a task-dependent default strategy similar to Listing's law. These and previous observations suggest two quasi-independent brain stem circuits: an oculomotor 2-D to 3-D transformation that coordinates anticipatory saccades with slow phases to uphold Listing's law, and a flexible "Fick operator" that selects head motor error; both nested within a dynamic gaze feedback loop. (+info)Definitive diagnosis of intestinal volvulus in utero. (4/379)
Midgut volvulus with or without intestinal malrotation can occur in fetal life. Several reports have described congenital midgut volvulus showing non-specific sonographic findings of intestinal obstruction and perforation in utero. None of the previously reported cases, however, were definitively diagnosed as midgut volvulus by fetal sonography. We report two cases both exhibiting the sonographic 'whirlpool' sign, in utero. Color Doppler interrogation provided a clue to the viability of the involved intestinal segment. (+info)Successful laparoscopic management of adnexal torsion during week 25 of a twin pregnancy. (5/379)
Adnexal torsion is a rare occurrence during pregnancy. Here we present a case of adnexal torsion during the 25th week of pregnancy, which was managed laparoscopically. The woman had achieved a successful twin pregnancy after in-vitro fertilization/intracytoplasmic sperm injection. She was admitted to the emergency department with acute abdominal pain. Abdominal ultrasound with colour Doppler mapping of the intra-ovarian blood flow showed adnexal torsion. Laparoscopic management was successfully carried out. (+info)Dissociated vertical deviation: an exaggerated normal eye movement used to damp cyclovertical latent nystagmus. (6/379)
PURPOSE: Dissociated vertical deviation (DVD) has eluded explanation for more than a century. The purpose of this study has been to elucidate the etiology and mechanism of DVD. METHODS: Eye movement recordings of six young adults with DVD were made with dual-coil scleral search coils under various conditions of fixation, illumination, and head tilt. Horizontal, vertical, and torsional eye movements were recorded for both eyes simultaneously. Analyses of the simultaneous vertical and torsional movements occurring during the DVD response were used to separate and identify the component vergence and version eye movements involved. RESULTS: Typically, both horizontal and cyclovertical latent nystagmus developed upon occlusion of either eye. A cycloversion then occurred, with the fixing eye intorting and tending to depress, the covered eye extorting and elevating. Simultaneously, upward versions occurred for the maintenance of fixation, consisting variously of saccades and smooth eye movements, leading to further elevation of the eye behind the cover. The cyclovertical component of the latent nystagmus became partially damped as the DVD developed. CONCLUSIONS: In patients with an early-onset defect of binocular function, the occlusion of one eye, or even concentration on fixing with one eye, produces unbalanced input to the vestibular system. This results in latent nystagmus, sometimes seen only with magnification. The cyclovertical component of the latent nystagmus, when present, is similar to normal vestibular nystagmus induced by dynamic head tilting about an oblique axis. Such vestibular nystagmus characteristically produces a hyperdeviation of the eyes. In the case of cyclovertical latent nystagmus, the analogous hyperdeviation will persist unless corrected by a vertical vergence. A normal, oblique-muscle-mediated, cycloversion/vertical vergence is called into play. This occurs in the proper direction to correct the hyperdeviation, but it occurs in an exaggerated form in the absence of binocular vision, probably as a learned response. The cycloversion/vertical vergence helps damp the cyclovertical nystagmus (a cyclovertical "nystagmus block-age" phenomenon), aiding vision in the fixing eye. But this mechanism also produces unavoidable and undesirable elevation and extortion of the fellow eye, which we call DVD. (+info)Alterations in the local myocardial motion pattern in patients suffering from pressure overload due to aortic stenosis. (7/379)
BACKGROUND: MR tissue tagging allows the noninvasive assessment of the locally and temporally resolved motion pattern of the left ventricle. Alterations in cardiac torsion and diastolic relaxation of the left ventricle were studied in patients with aortic stenosis and were compared with those of healthy control subjects and championship rowers with physiological volume-overload hypertrophy. METHODS AND RESULTS: Twelve aortic stenosis patients, 11 healthy control subjects with normal left ventricular function, and 11 world-championship rowers were investigated for systolic and diastolic heart wall motion on a basal and an apical level of the myocardium. Systolic torsion and untwisting during diastole were examined by use of a novel tagging technique (CSPAMM) that provides access to systolic and diastolic motion data. In the healthy heart, the left ventricle performs a systolic wringing motion, with a counterclockwise rotation at the apex and a clockwise rotation at the base. Apical untwisting precedes diastolic filling. In the athlete's heart, torsion and untwisting remain unchanged compared with those of the control subjects. In aortic stenosis patients, torsion is significantly increased and diastolic apical untwisting is prolonged compared with those of control subjects or athletes. CONCLUSIONS: Torsional behavior as observed in pressure- and volume-overloaded hearts is consistent with current theoretical findings. A delayed diastolic untwisting in the pressure-overloaded hearts of the patients may contribute to a tendency toward diastolic dysfunction. (+info)Laparoscopic diagnosis and management of ovarian torsion in the newborn. (8/379)
BACKGROUND AND OBJECTIVES: The application of laparoscopic techniques in the surgical management of neonatal ovarian cysts is proving valuable both as a diagnostic tool and a potential therapeutic intervention. We report the successful management of a prenatally diagnosed ovarian cyst in a newborn female and provide operative evidence for the presumptive etiology of the cyst. METHODS AND RESULTS: A prenatally diagnosed ovarian cyst was managed using 5 mm laparoscopic instruments in a newborn female. The prenatal ultrasonographic and operative findings are consistent with in utero adnexal torsion with subsequent autoamputation and cystic degeneration of the ovary. The orphaned ovarian cyst was removed from the infant's abdominal cavity by enlarging the camera port incision. DISCUSSION: The application of laparoendoscopic procedures in infants and children continues to evolve with the availability, of microinstrumentation and increasing experience among pediatric surgeons. This approach may prove valuable in the diagnosis and management of prenatally diagnosed ovarian cysts. In addition, further insight into the etiology of congenital ovarian cysts may be obtained. The safety and efficacy of this approach in these infants remains to be fully evaluated. (+info)A "torsion abnormality" is not a standard medical term, but I believe you are asking about torsional deformities or abnormalities related to torsion. Torsion refers to a twisting force or movement that can cause structures to rotate around their long axis. In the context of medical definitions:
Torsional abnormality could refer to a congenital or acquired condition where anatomical structures, such as blood vessels, muscles, tendons, or bones, are twisted or rotated in an abnormal way. This can lead to various complications depending on the structure involved and the degree of torsion.
For instance, in congenital torsional deformities of long bones (like tibia or femur), the rotation of the bone axis can cause issues with gait, posture, and joint function. In some cases, this may require surgical intervention to correct the abnormality.
In the context of vascular torsion abnormalities, such as mesenteric torsion, it could lead to bowel ischemia due to the twisting of blood vessels that supply the intestines. This can be a surgical emergency and requires immediate intervention to restore blood flow and prevent further damage.
It's essential to consult with a medical professional for a precise diagnosis and treatment options if you or someone else experiences symptoms related to torsional abnormalities.
Spermatic cord torsion is a urological emergency that refers to the twisting of the spermatic cord, which contains the vas deferens, blood vessels (testicular artery and pampiniform plexus), nerves, and lymphatics. This twisting results in the compromise of the blood supply to the testicle, leading to potential ischemia, necrosis, and loss of the testicle if not promptly diagnosed and treated.
The spermatic cord torsion mainly affects the pediatric population, particularly newborns and adolescents; however, it can also occur in adults, especially those with a history of an undescended testicle or previous episodes of torsion. The most common presenting symptom is sudden onset of severe scrotal pain, often associated with nausea, vomiting, and fever. A physical examination may reveal swelling, tenderness, and elevation of the affected testicle (known as a high-riding or "bell clapper" testicle). Diagnosis typically involves imaging studies such as ultrasound or Doppler ultrasonography, although in some cases, surgical exploration might be necessary for definitive diagnosis and treatment.
Treatment of spermatic cord torsion usually involves prompt surgical intervention to untwist the spermatic cord and secure the affected testicle to the scrotal wall (orchidopexy) to prevent recurrence. Delayed diagnosis and treatment can lead to severe complications, including loss of the testicle, infertility, and chronic pain.
Mechanical torsion in a medical context refers to the twisting or rotational deformation of a body or structure due to an applied torque or force. This can occur in various biological structures, such as blood vessels, intestines, or muscles, leading to impaired function, pain, or even tissue necrosis if severe or prolonged.
For example, in the case of the gastrointestinal tract, torsion can cause a segment of the bowel to twist around its own axis, cutting off blood flow and causing ischemia or necrosis. This is a surgical emergency that requires prompt intervention to prevent further complications. Similarly, in the eye, torsion can refer to the rotation of the eyeball within the orbit, which can cause double vision or other visual disturbances.
'Dystonia Musculorum Deformans' is a medical term that refers to a rare inherited neurological disorder, which is now more commonly known as "Generalized Dystonia." This condition is characterized by sustained muscle contractions, leading to twisting and repetitive movements or abnormal postures.
The onset of symptoms typically occurs during childhood or adolescence, and they can progress over time, affecting various parts of the body. The exact cause of Generalized Dystonia is not fully understood, but it is believed to involve genetic mutations that affect the functioning of certain proteins in the brain. Treatment options may include medications, botulinum toxin injections, or even deep brain stimulation surgery in severe cases.
Ovarian diseases refer to a range of conditions that affect the function and health of the ovaries, which are the female reproductive organs responsible for producing eggs (oocytes) and female hormones estrogen and progesterone. These diseases can be categorized into functional disorders, infectious and inflammatory diseases, neoplastic diseases, and other conditions that impact ovarian function. Here's a brief overview of some common ovarian diseases:
1. Functional Disorders: These are conditions where the ovaries experience hormonal imbalances or abnormal functioning, leading to issues such as:
* Polycystic Ovary Syndrome (PCOS): A condition characterized by hormonal imbalances that can cause irregular periods, cysts in the ovaries, and symptoms like acne, weight gain, and infertility.
* Functional Cysts: Fluid-filled sacs that develop within the ovary, usually as a result of normal ovulation (follicular or corpus luteum cysts). They're typically harmless and resolve on their own within a few weeks or months.
2. Infectious and Inflammatory Diseases: These conditions are caused by infections or inflammation affecting the ovaries, such as:
* Pelvic Inflammatory Disease (PID): An infection that spreads to the reproductive organs, including the ovaries, fallopian tubes, and uterus. It's often caused by sexually transmitted bacteria like Chlamydia trachomatis or Neisseria gonorrhoeae.
* Tuberculosis (TB): A bacterial infection that can spread to the ovaries and cause inflammation, abscesses, or scarring.
3. Neoplastic Diseases: These are conditions where abnormal growths or tumors develop in the ovaries, which can be benign (non-cancerous) or malignant (cancerous). Examples include:
* Ovarian Cysts: While some cysts are functional and harmless, others can be neoplastic. Benign tumors like fibromas, dermoids, or cystadenomas can grow significantly larger and cause symptoms like pain or bloating. Malignant tumors include epithelial ovarian cancer, germ cell tumors, and sex cord-stromal tumors.
4. Other Conditions: Various other conditions can affect the ovaries, such as:
* Polycystic Ovary Syndrome (PCOS): A hormonal disorder that causes enlarged ovaries with small cysts. It's associated with irregular periods, infertility, and increased risk of diabetes, high blood pressure, and heart disease.
* Premature Ovarian Failure (POF): Also known as primary ovarian insufficiency, it occurs when the ovaries stop functioning before age 40, leading to menstrual irregularities, infertility, and early onset of menopause.
It's essential to consult a healthcare professional if you experience any symptoms related to your reproductive system or suspect an issue with your ovaries. Early detection and treatment can significantly improve the prognosis for many conditions affecting the ovaries.
In the context of medicine, particularly in anatomy and physiology, "rotation" refers to the movement of a body part around its own axis or the long axis of another structure. This type of motion is three-dimensional and can occur in various planes. A common example of rotation is the movement of the forearm bones (radius and ulna) around each other during pronation and supination, which allows the hand to be turned palm up or down. Another example is the rotation of the head during mastication (chewing), where the mandible moves in a circular motion around the temporomandibular joint.
The scrotum is a part of the external male genitalia. It's a sac-like structure made up of several layers of skin and smooth muscle, which hangs down behind and beneath the penis. The primary function of the scrotum is to maintain the testicles at a temperature slightly lower than the core body temperature, which is optimal for sperm production.
The scrotum contains two compartments, each one housing a testicle. It's located in the pubic region and is usually visible externally. The skin of the scrotum is thin and wrinkled, which allows it to expand and contract depending on the temperature, accommodating the shrinking or swelling of the testicles.
Please note that while I strive to provide accurate information, this definition is intended to be a general overview and should not replace professional medical advice.

- If the pain is severe, or sudden in onset but not midcycle - which is suggestive of ovulation pain (Mittleschmirtz) - the woman may require same-day emergency care in case of an ovarian accident, such as torsion or rupture. (pulsetoday.co.uk)
Anatomical1
- Abnormalities can range from anatomical associated with degree or site of inplantation, structure (as with twinning), to placental function, placento-maternal effects (pre-eclampsia, fetal erythroblastosis) and finally mechanical abnormalities associated with the placental (umbilical) cord. (edu.au)
Etiology1
- We present a case of gallbladder torsion and review the literature on etiology, clinical presentation, radiological diagnosis, and intraoperative pitfalls. (sls.org)
Dystonia3
- We aimed to assess the frequency of temporal discrimination threshold (TDT) abnormities in sporadic adult-onset primary torsion dystonia (AOPTD) patients and their first degree relatives. (bmj.com)
- In the 23 cervical dystonia patients, TDT abnormalities were detected in 100% of cases. (bmj.com)
- According to previous research, carriers of the DYT1 dystonia mutation exhibit abnormalities in the cerebellothalamocortical motor pathways. (tylershope.org)
Ultrasound2
- However, if the ultrasound scan shows pathology, such as endometrioma or other abnormality, referral should be made. (pulsetoday.co.uk)
- Incidence of hip dysplasia/dislocation is rare (7 per 1000 births), and universal screening programs using ultrasound on infants without obvious hip abnormalities identify few cases and have a considerable false-positive rate. (medscape.com)
Uncommon1
- Gallbladder torsion is uncommon and difficult to diagnose before surgery. (sls.org)
Diagnosis1
- Hence, the diagnosis is often made late, long after the torsion event has taken place. (medscape.com)
Gastrointestinal2
- A case of gastrointestinal torsion with dilatation in a farm-raised channel catfish ( Ictalurus punctatus ) was examined at the Thad Cochran National Warmwater Aquaculture Center (Stoneville, Mississippi, USA). (allenpress.com)
- When examining cases of abdominal distention in fish, gastrointestinal torsion can be considered among the differential diagnoses. (allenpress.com)
Occur1
- However, torsion may occasionally occur in men of 40-50 years old [6]. (lupinepublishers.com)
Humans1
- These findings link a selective brain circuit abnormality to gene carrier status and demonstrate the similar effect of DYT1 mutatnt torsion A on humans and mice. (tylershope.org)
Femoral1
- Hence, this model enables rapid and accurate estimation of muscle-tendon lengths and moment arms for individuals with a wide range of movement abnormalities and femoral deformities. (simtk.org)
Infertility1
- Thus, MSCs may potentially rescue torsion-detorsion-induced infertility via local injection. (biomedcentral.com)
Spermatic cord1
- A rotational twisting of the spermatic cord is the basis of all torsion events. (medscape.com)
Absence2
- In the absence of accurate guidelines for management, we must start with the development of more accurate methods for diagnosing associated complications such as torsion. (degruyter.com)
- [ 3 , 4 ] Their original classification system stratified the ectodermal dysplasias into different subgroups according to the presence or absence of (1) hair anomalies or trichodysplasias, (2) dental abnormalities, (3) nail abnormalities or onychodysplasias, and (4) eccrine gland dysfunction or dyshidrosis. (medscape.com)
Necrosis2
- If the stomach appears viable with no evidence of necrosis (dead or devitalized tissue from decreased blood supply) and has not ruptured, a gastropexy will be performed to tack the stomach to the body wall surgically to prevent recurrence of volvulus (torsion or twisting of the stomach) or GDV. (friendshiphospital.com)
- At microscopic exam, the lobe with torsion showed fibrosis and necrosis areas. (vin.com)
Secondary1
- Probably, the main disease was the lung lobe torsion, with secondary dilated cardiomyopathy and hepatomegaly. (vin.com)
Frequency1
- A multi-function output terminal, can realize the indication and alarm during operation, frequency arrival, external abnormality, etc. (variablespeedcar.com)
Common1
- Introduction to Congenital Craniofacial and Musculoskeletal Abnormalities Craniofacial and musculoskeletal abnormalities are common among children. (merckmanuals.com)
Unusual2
- A gait abnormality is an unusual way of walking. (firstwalkers.com)
- Lung lobe torsion (LLT) is an unusual life threatening disease in dogs. (vin.com)
Gene1
- Sensory abnormalities in unaffected relatives may indicate nonmanifesting gene carriage. (bmj.com)
