Congenital kyphosis in myelomeningocele. The effect of cordotomy on bladder function. (1/105)

To determine the effect of cordotomy on the function of the bladder during surgical correction of congenital kyphosis in myelomeningocele, we reviewed 13 patients who had this procedure between 1981 and 1996. The mean age of the patients at operation was 8.9 years (3.7 to 16) and the mean follow-up was 4.8 years (1.3 to 10.8). Bladder function before and after operation was assessed clinically and quantitatively by urodynamics. The mean preoperative kyphosis was 117 degrees (52 to 175) and decreased to 49 degrees (1 to 89) immediately after surgery. At the latest follow-up, a mean correction of 52% had been achieved. Only one patient showed deterioration in bladder function after operation. Eight out of the nine patients who had urodynamic assessment had improvement in bladder capacity and compliance, and five showed an increase in urethral pressure. One patient developed a spastic bladder and required subsequent surgical intervention. Cordotomy, at or below the level of the kyphosis, allows excellent correction of the structural deformity.  (+info)

Percutaneous cervical cordotomy for the control of pain in patients with pleural mesothelioma. (2/105)

BACKGROUND: Severe chest pain is common in mesothelioma. Percutaneous cervical cordotomy, which interrupts the spinothalamic tract at the C1/C2 level causing contralateral loss of pain sensation, is particularly appropriate in mesothelioma as the tumour is unilateral and systemic analgesia may be ineffective and is limited by harmful side effects. METHOD: A retrospective review was performed to determine the effectiveness and complication rate of this procedure. RESULTS: Fifty two patients were using opioids prior to cordotomy. The median daily dose of morphine before and after cordotomy was 100 mg (range 0-1000 mg) and 20 mg (range 0-520 mg), respectively (p < 0.001). Forty three patients (83%) had a reduction in pain such that their dose of opioid could be at least halved. Twenty patients (38%) were able to stop completely. Recurrence of pain requiring an increase in opioid medication was recorded in 18 patients at a median time of nine weeks (range 0.7-26 weeks). Four patients developed mild weakness, two had troublesome dysaesthesia. The median time from cordotomy to death was 13 weeks (range 0.3-52 weeks). Six early deaths within two weeks of cordotomy occurred early in the series and reflect postoperative chest infection and poor selection as the patients were in the terminal stages of mesothelioma. CONCLUSIONS: Percutaneous cervical cordotomy is successful in treating pain from mesothelioma. There was a low complication rate in this series. Referral to a unit experienced in cordotomy is recommended as soon as pain from chest wall invasion is suspected.  (+info)

Persistence of hybrid fibers in rat soleus after spinal cord transection. (3/105)

The effects of a chronic (up to 360 days) reduction in neuromuscular activity (defined as electrical activation and loading) on myosin heavy chain (MHC) isoform expression in the rat soleus muscle were studied. A complete mid-thoracic (T7-T8) spinal cord transection (ST) was used to induce a reduction in soleus muscle neuromuscular activity. Electrophoretic analyses revealed that MHC-I was progressively decreased after ST, accounting for approx. 90% of the total soleus MHC in controls and only approx. 12% 1 year after ST. The reductions in the proportion of MHC-I were countered by increases in MHC-IIa and MHC-IIx with the increase in MHC-IIx preceding the increase in MHC-IIa. Curiously, MHC-IIb was expressed only at very low levels. Thus, a complete transformation from predominantly MHC-I to MHC-IIb did not occur. Many fibers (up to approx. 80%) contained multiple MHCs (hybrid fibers) after ST. The proportion of hybrid fibers was maintained at a high level (approx. 50%) 1 year after ST. These data suggest that: 1) a prolonged reduction in neuromuscular activity was not sufficient to induce high level MHC-IIb expression by the soleus muscle; and 2) hybrid fibers were not simply transitional fibers. Thus, it appears that under appropriate conditions hybrid fibers may represent a "stable" fiber phenotype.  (+info)

The analgesic action of nitrous oxide is dependent on the release of norepinephrine in the dorsal horn of the spinal cord. (4/105)

BACKGROUND: The authors and others have demonstrated that supraspinal opiate receptors and spinal alpha2 adrenoceptors are involved in the analgesic mechanism for nitrous oxide (N2O). The authors hypothesize that activation of opiate receptors in the periaqueductal gray results in the activation of a descending noradrenergic pathway that releases norepinephrine onto alpha2 adrenoceptors in the dorsal horn of the spinal cord. METHODS: The spinal cord was transected at the level of T3-T4 in rats and the analgesic response to 70% N2O in oxygen was determined by the tail flick latency test. In a separate experiment in rats a dialysis fiber was positioned transversely in the dorsal horn of the spinal cord at the T12 level. The following day, the dialysis fiber was infused with artificial cerebrospinal fluid at a rate of 1.3 microl/min, and the effluent was sampled at 30-min intervals. After a 60-min equilibration period, the animals were exposed to 70% N2O in oxygen. The dialysis experiment was repeated in animals that were pretreated with naltrexone (10 mg/kg, intraperitoneally) before N2O. In a third series, spinal norepinephrine was depleted with n-(2-chloroethyl)-n-ethyl-2-bromobenzylamine (DSP-4), and the analgesic response to 70% N2O in oxygen was determined. RESULTS: The analgesic effect of N2O was prevented by spinal cord transection. After exposure to N2O, there was a fourfold increase in norepinephrine released in the first 30-min period, and norepinephrine was still significantly elevated after 1 h of exposure. The increased norepinephrine release was prevented by previous administration of naltrexone. Depletion of norepinephrine in the spinal cord blocked the analgesic response to N2O. CONCLUSIONS: A descending noradrenergic pathway in the spinal cord links N2O-induced activation of opiate receptors in the periaqueductal gray, with activation of alpha2 adrenoceptors in the spinal cord. N2O-induced release of norepinephrine in the dorsal horn of the spinal cord is blocked by naltrexone, as is the analgesic response. Spinal norepinephrine is necessary for the analgesic response to the N2O.  (+info)

Central regulation of sympathetic neuron development. (5/105)

The sixth lumbar (L-6) ganglion has been used to study the central regulation of peripheral sympathetic neuron development. During post-natal ontogeny, tyrosine hydroxylase [tyrosine 3-monooxygenase, L-tyrosine, tetrahydropteridine: oxygen oxidoreductase (3-hydroxylating), EC 1.14.16.2] activity increased 60-fold, while total protein rose 10-fold in the ganglion. Transection of the spinal cord at the fifth thoracic (T-5) segment in neonatal rats prevented the normal developmental increase in tyrosine hydroxylase activity of the L-6 ganglion. However, spinal transection did not alter the ontogeny of tyrosine hydroxylase in the superior cervical ganglion, which derives its innervation from spinal segments rostral to the surgical lesion. Thus, spinal transection interfered with the maturation of sympathetic neurons distal to, but not proximal to, the lesion. The effect of transection on the L-6 ganglion persisted for at least one month, the longest time tested. Our observations suggest that trans-synaptic regulation of adrenergic maturation in the periphery is governed by suprasegmental mechanisms in the central nervous system.  (+info)

The effect of 2-deoxy-D-glucose and D-glucose on the efferent discharge rate of sympathetic nerves. (6/105)

Efferent discharges were recorded from nerve filaments dissected from the adrenal and renal nerves in the rabbit. 2. An increase in discharge rate was observed in the adrenal nerve filaments following I.V. administration of 2-deoxy-D-glucose (2-DG). No change in discharge rate after 2-DG infusion was observed in the renal nerve filaments. 3. A decrease in discharge rate of the adrenal nerve filaments was observed after I.V. injection of glucose, but there was no change in the activity of renal nerve filaments. 4. Transection of the spinal cord abolished the adrenal nerve response to the systemic administration of 2-DG and glucose. 5. It is suggested that there might be a pathway from the hypothalmic area to the adrenal nerve cells of the spinal cord, but not to the renal nerve cells, through which activity of the adrenal nerve might be changed in response to 2-DG and glucose infusion.  (+info)

High cervical commissural myelotomy in the treatment of pain. (7/105)

High cervical myelotomy was carried out on 10 patients. Commissurotomy was performed at the C1-3 level by a combined procedure of deep electrocogulation and sharp splitting of the posterior columns. The immediate results were excellent in all patients, but relapse of pain took place shortly in six of them; there was apparently no relation with the location of pain. No long-term favourable results were observed in this series. Only three patients exhibited a well-defined band of mild hypalgesia from C2 to T 10 dermatome, but it lasted for only three to four weeks. Transient lower or four limb ataxia was observed in seven patients. Different pain conducting systems seem to be affected by commissural myelotomy, but not to a sufficient extent to give permanent or long-lasting relief of pain. The indications for high cervical myelotomy are very limited: this procedure should be considered only in patients with unilateral or bilateral arm and/or upper chest pain, respiratory impairment, and short life expectancy.  (+info)

The crossing of the spinothalamic tract. (8/105)

The question whether the spinothalamic and spinoreticular fibres cross the cord transversely or diagonally was investigated in cases of anterolateral cordotomy and in a case of thrombosis of the anterior spinal artery. The pattern of sensory loss following transection of the anterolateral quadrant of the cord consists of a narrow area of decreased nociception and thermanalgesia at the level of the incision; it extends for 1-2 segments cranial and cordal to the incision. This area is immediately cranial to the area of total loss of these modalities. This pattern of sensory loss is explained as follows. The cordotomy incision transects two groups of fibres: those that are already within the anterior and anterolateral funiculi and those that are crossing the cord. The area of total thermanaesthesia and analgesia is due to transection of fibres that are already within this region. The area of partial sensory loss is due to transection of the fibres that are crossing the cord at that level. Owing to the craniocaudal extent of the branches of the dorsal roots, there is an overlap of their collaterals that results in every spinothalamic neurone receiving an input from several dorsal roots. The narrow cordotomy incision thus divides the few fibres crossing at that level, causing diminished noxious and thermal sensibility over a few segments above and below the incision. These facts can be accounted for only on the assumption that these spinothalamic fibres are crossing the cord transversely. This evidence of transverse crossing was found in the cervical, thoracic and lumbar segments. There were three of 63 cordotomies for which this explanation of the partial sensory loss could not be maintained. Although no explanation has been suggested, this is unlikely to be due to the fibres crossing the cord diagonally.  (+info)

It can be inferred that most of the patients in this series (83%) had a significant reduction in pain, and 20 of 52 (38%) were able to stop opioid medication completely. This is an important finding in pleural mesothelioma as the pain is often severe and opioid resistant. This is a retrospective review, however, with all the problems inherent therein. Some data were difficult to confirm because we can only be sure of relevant data that were recorded in the individual case notes. In particular, the lowest dose of morphine following the procedure, the use of co-analgesic medication, the recurrence of pain, and the incidence of minor complications may not have been recorded in some cases. In any procedure where the primary aim is palliation, quality of life should be considered, and it can be argued that the dose of opioid is not necessarily the best indicator of a satisfactory result in cordotomy. In a retrospective review, though, it is the best quantifiable variable. In a prospective study other ...

Otfrid Foerster (9 November 1873, in Breslau, Silesia - 15 June 1941, also in Breslau) was a German neurologist and neurosurgeon, who made innovative contributions to neurology and neurosurgery, such as rhizotomy for the treatment of spasticity, anterolateral cordotomy for pain, the hyperventilation test for epilepsy, Foersters syndrome, the first electrocorticogram of a brain tumor, and the first surgeries for epilepsy. He is also known as the first to describe the dermatomes (an area of skin that is supplied by a single pair of dorsal nerve roots), and he helped map the motor cortex of the cerebrum [1] . Foerster was born in Breslau to Richard Foerster, and studied in the Maria Magdalenen Gymnasium, graduating 1892. From 1892 to 1896 he studied medicine in Freiburg, Kiel and Breslau, obtaining his licensure by state examination in 1897 and his doctorate in the same year. Upon completion of the doctoral studies, he spent two years studying abroad, following a suggestion by Karl Wernicke ...

The eponym Ondines curse in the medical literature usually refers to the failure of automatic respiratory drive with intact voluntary respiration. Ondine was a mythological water nymph who became human by falling in love with a mortal. The now-entrenched eponym is actually a misnomer, as Ondine has never cursed anyone. Patients affected by Ondines curse can have prolonged periods of apnea or hypopnea, particularly during sleep. They may require nocturnal mechanical ventilation but depending on the cause, this may be temporary. Infarction involving the medulla is one of the most common causes of Ondines curse. Other reported causes include loss of vagal and chemotactic input to the medullary carbon dioxide receptors, bulbar polio causing damage to the reticulospinal pathways, cervical cordotomy for pain control, and anterior spinal artery infarction..

The authors present a review of contemporary concepts in surgical pain management, with reference to past successes and failures, what has been learned as a subspecialty over the past 50 years, as well as a vision for current and future practice. This subspecialty confronts problems of cancer pain, nociceptive pain, and neuropathic pain. For noncancer pain, ablative procedures such as dorsal root entry zone lesions and rhizolysis for trigeminal neuralgia (TN) should continue to be practiced. Other procedures, such as medial thalamotomy, have not been proven effective and require continued study. Dorsal rhizotomy, dorsal root ganglionectomy, and neurotomy should probably be abandoned. For cancer pain, cordotomy is an important and underutilized method for pain control. Intrathecal opiate ...
The exact definition of intractable pain varies based on the source and is not generally agreed upon. Several states (California, Colorado, Florida, New Jersey, Texas, Virginia, Minnesota and Washington[1]) have passed intractable pain laws or guidelines. Texas, under their Intractable Pain Treatment Act, defines Intractable Pain as a state of pain for which the cause of the pain cannot be removed or otherwise treated and in the generally accepted course of medical practice, relief or cure of the cause of the pain is not possible or has not been found after reasonable efforts.[2] Floridas Intractable Pain statute defines intractable pain as pain for which, in the generally accepted course of medical practice, the cause cannot be removed and otherwise treated.[3] ...
Once the electrical stimulator was implanted, Summers began spinal cord stimulation during therapy sessions lasting up to 4 hours. On just his third try, researchers were astounded that he was able to not only move, but stand up using only minimal support. When Rob regained voluntary control of his leg, I was afraid to believe it when I saw it, said Harkemas research partner Reggie Edgerton, Ph.D in a news conference. What nobody has ever demonstrated is that epidural stimulation at modest levels enables an individual to have conscious control of body motion. Someone with paralysis for several years can now control his movement. This has never been done before. Only 7 months later Summers was able to regain some his own control over his legs and feet by moving them on command during spinal stimulation sessions. He also has regained control over his bowls, bladder and sexual function - which were lost when he became paralyzed. Being able to move my ankles, my toes, my knees -- there are not ...

In this self-selected group of respondents, the numbers of people who rated themselves as very comfortable ranged from 5-45 percent for the various procedures, with most in the 20 percent range. With respect to frequency of performing procedures, none had done more than 10 for any single one. Most had done five or less. In addition, there was a fair amount of heterogeneity in approaches (Table 1). There was considerable interest in hands on training, with the greatest interest in DREZ and midline myelotomy. Most (68 percent) were interested in participating in a national neuroablation registry, and there was considerable interest (55 percent) in being contacted to serve as an instructor.. Neuroablation is clearly of interest to the neurosurgery community, as evidenced from this survey and the recent well-attended Pain Section Biennial Meeting in Chicago, in May 2017. However, it will take significant effort to get these techniques to patients who could benefit from them but can be done so by ...

Intractable sciatica can destroy lives and make a normal existence quite impossible. Intractable pain has become a growing burden throughout the health system.
Spinal cord injury (SCI) disconnects supraspinal micturition centers from the lower urinary tract resulting in immediate and long-term changes in bladder structure and function. While cervical and high thoracic SCI have a greater range of systemic effects, clinical data suggest that those with lower (suprasacral) injuries develop poorer bladder outcomes. Here we assess the impact of SCI level on acute changes in bladder activity. We used two SCI models, T3 and L2 complete transections in male Wistar rats, and compared bladder pressure fluctuations to those of naïve and bladder-denervated animals. By 2 days after L2 transection, but not T3 transection or bladder denervation, small amplitude rhythmic contractions (1 mmHg, 0.06 Hz) were present at low intravesical pressures (

Between the two latter diverticula is a mass of mesoderm containing the ducts of Cuvier, and this is continuous ventrally with the mesoderm in which the umbilical veins are passing to the sinus venosus. A septum of mesoderm thus extends across the body of the embryo. It is attached in front to the body-wall between the pericardium and umbilicus; behind to the body-wall at the level of the second cervical segment; laterally it is deficient where the pericardial and pleuro-peritoneal cavities communicate, while it is perforated in the middle line by the foregut. This partition is termed the septum transversum, and is at first a bulky plate of tissue. As development proceeds the dorsal end of the septum is carried gradually caudalward, and when it reaches the fifth cervical segment muscular tissue with the phrenic nerve grows into it. It continues to recede, however, until it reaches the position of the adult diaphragm on the bodies of the upper lumbar vertebræ. The liver buds grow into the septum ...
Intractable Pain - Intractable pain is chronic pain that cannot be treated or removed by usual medical treatments or by natural healing. Intractable pain is debilitating, constant, and incurable even after efforts to relieve this pain made by physicians and surgeons that specialize in treating the part of the body acting as the source of the pain. This type of pain can cause elevations of pulse, blood pressure, and adrenal gland hormones, but vital signs can also be normal in children experiencing chronic, intractable pain. Untreated pain has severe long-term consequences and multi-system effects on ability to heal, sleep patterns, appetite/nutritional status, social engagement, coping skills, emotional stability, and life enjoyment, to name only a few. Early untreated pain that becomes intractable in young children interferes with normal nervous system development and can cause long-term problems with pain management throughout life ...

MarketReportsOnline.com adds Global Spine Market Report: 2013 Edition report to its research store.. The spine market is the largest segment within the global orthopedic market. There are four categories of spine disorders: degenerative conditions, deformities, tumor and trauma-based disorders. Spinal implants include both fusion and non-fusion devices: devices associated with vertebral compression fracture (VCF), interbody devices, cervical, thoracolumbar, and spinal stimulation devices.. The US is the largest market for spinal surgeries and is expected to achieve significant growth on the account of aging population, growing number of younger patients, changing lifestyles and product innovations. However, the spine market in the US has experienced slowdown in 2012 and continues to be plagued with factors like pricing pressures on manufacturers and slumping insurance coverage..

Spinal cord injury, involving damaged axons and glial scar tissue, often culminates in irreversible impairments. Achieving substantial recovery following complete spinal cord transection remains an unmet challenge. Here, we report of implantation of an engineered 3D construct embedded with human oral mucosa stem cells (hOMSC) induced to secrete neuroprotective, immunomodulatory and axonal elongation-associated factors, in a complete spinal cord transection rat model. Rats implanted with induced tissue engineering constructs regained fine motor control, coordination and walking pattern in sharp contrast to the untreated group that remained paralyzed (42% vs. 0%). Immunofluorescence, CLARITY, MRI and electrophysiological assessments demonstrated a reconnection bridging the injured area, as well as presence of increased number of myelinated axons, neural precursors, and reduced glial scar tissue in recovered animals treated with the induced cell-embedded constructs. Finally, this construct is made of bio
Quantitative MRI techniques have the potential to characterize spinal cord tissue impairments occurring in various pathologies, from both microstructural and functional perspectives. By enabling very high image resolution and enhanced tissue contrast, ultra-high field imaging may offer further opportunities for such characterization. In this study, a multi-parametric high-resolution quantitative MRI protocol is proposed to characterize in vivo the human cervical spinal cord at 7T. Multi-parametric quantitative MRI acquizitions including T1, T2(*) relaxometry mapping and axial diffusion MRI were performed on ten healthy volunteers with a whole-body 7T system using a commercial prototype coil-array dedicated to cervical spinal cord imaging. Automatic cord segmentation and multi-parametric data registration to spinal cord templates enabled robust regional studies within atlas-based WM tracts and GM horns at the C3 cervical level. T1 value, cross-sectional area and GM/WM ratio evolutions along the cervical

Excellent case and Good work. Compliment you on your innovative thinking in the execution of a rather difficult third time redo operation. Signification points to high light: 1. Ability to do redo cases by single venous cannulation, if there is no intracardiac defect which needs attention. 2. Complete transection of the aorta to expose the bifurcation and pa branches, as this give unimpeded exposure and very good conditions to work on pa branches. 3, Division of aorta also gives excellent exposure for aortic valve repair.
