Surgical treatment of limb-length discrepancy following total hip arthroplasty.

BACKGROUND: Although most patients with limb-length discrepancy following total hip arthroplasty have manageable symptoms, others may be disabled as a result of pain or functional impairment. In these patients, reoperation may be indicated to equalize the limb lengths. There is a paucity of published data regarding the outcome of surgical intervention to treat this problem. The purpose of the present study was to evaluate the results of revision hip surgery for the treatment of symptomatic limb-length discrepancy. METHODS: We retrospectively reviewed the clinical and radiographic records of patients who had undergone revision hip surgery at our institution for the treatment of a symptomatic limb-length discrepancy following a previous total hip arthroplasty. We identified twenty-one patients (twenty-one hips) who had an average age of sixty-six years at the time of revision hip arthroplasty. The average duration of follow-up was 2.8 years, and no patient was lost to follow-up. The indications for revision hip arthroplasty were severe hip and/or back pain for eleven patients, instability of the hip for eight, hip pain and ipsilateral limb paresthesia for one, and hip pain and ipsilateral foot drop for one. RESULTS: Revision arthroplasty was performed at a mean of eight months (range, six days to six years) after primary total hip replacement. The mean limb-length discrepancy at the time of the revision was 4 cm (range, 2 to 7 cm). Following revision arthroplasty, which involved revision of a malpositioned acetabular and/or femoral component, equalization of the limb lengths was achieved in fifteen patients. In the remaining six patients, the mean discrepancy had decreased to 1 cm. The mean Harris hip score improved significantly, from 56.5 points before the revision to 83.2 points at the time of the latest follow-up (p < 0.005). All but two patients were satisfied with the outcome of the revision surgery. CONCLUSIONS: Limb-length discrepancy following hip arthroplasty can be associated with pain, paresthesia, and hip instability. In these patients, careful evaluation of the position and orientation of the components may reveal the cause of the discrepancy. Revision arthroplasty may be indicated when a surgically correctable cause of limb-length discrepancy can be identified.

Documentation of acute compartment syndrome at an academic health-care center.

BACKGROUND: Documentation of the clinical course of a compartment syndrome is critical to effective treatment; however, such documentation often is found to be inadequate. METHODS: Notes and consent forms for thirty consecutive patients with adequate follow-up who had undergone fasciotomy for the treatment of compartment syndrome were reviewed for legibility, notation of the time and date, and documentation of the presence of core physical examination and history findings, including pain, paresthesias, tenseness, pain on passive stretch, sensory deficit, motor deficit, pulses, compartment pressures, and diastolic blood pressure. RESULTS: Documentation was inadequate for twenty-one patients (70%): the notes and consent forms were not timed or not dated (or both) for nine patients (30%), and the notes were at least partially illegible for sixteen patients (53%). The documentation was incomplete with regard to the presence of paresthesias in eleven patients, pain on passive stretch in ten, sensory deficit in nine, motor deficit in eight, pulses in seven, pain in five, and tenseness in three. The documentation was incomplete with regard to the blood and compartment pressures for sixteen and six patients, respectively. CONCLUSIONS: The documentation of the core history and physical examination findings was inadequate in this series of patients with compartment syndrome. On the basis of the results of this study, and through an organizational systems approach, we have instituted for our residents, nursing staff, and faculty an educational program on the documentation of compartment syndrome in patients who are at risk for this condition.

[Neurophysiological and clinical aspect of patients with carpal tunnel syndrome].

In the group of patients with carpal tunnel syndrome (CTS), besides paresthesias in their fingers, we can see paresthesias in forearm; pain in elbow, sholder and neck, which is a reason for complicated diagnosis of it. This kind of complexnost of differential diagnosis pain in hand, is a reason for complet and strict diagnostic procedure. There are 30 patients with clinical and neurophysological findings for CTS in this paper who made provocative tests. Analising their results we made diagnosis of KTS.

An analysis of poison control center reports of ciguatera toxicity in Puerto Rico for one year.

Forty-five cases of ciguatera poisoning in Puerto Rico (P.R.) are described. These cases represent all those reported to the P.R. Poison Control Center in 1982. Most of the cases were reported in the spring and summer months. The most common fish ingested was the grouper. The clinical presentation of acute and long term symptoms was similar to that reported in other geographical areas, except the incidence of paresthesias. Paresthesias were reported in 11% of the patients reported to the poison center. A companion telephone survey indicated that persons in P.R. that do not eat fish do so because of fear of ingesting the toxin. Our findings indicate an overall familial contact with the ciguatera toxin in Puerto Rico at 7%. This study is the first to document that ciguatera is a common poisoning reported to the Poison Control Center in Puerto Rico. Our findings also support other authors contentions of geographical variations in clinical symptomatology.

Spinal cord stimulation with percutaneous and plate electrodes: side effects and quantitative comparisons.

Spinal cord stimulation is limited by the uncomfortable side effects experienced by the patient as the amplitude of stimulation is increased. These side effects include local segmental paresthesias or motor responses, which are objectively demonstrable as frequency-following muscle contractions, attributable to dorsal root stimulation. The authors present evidence for another mechanism of stimulation-evoked discomfort, namely recruitment of small fibers in ligamentum flavum, which occurs when electrodes are inserted percutaneously and their contacts are exposed circumferentially; this does not occur with plate electrodes with insulated dorsal surfaces. In a consecutive series of 79 patients with postsurgical lumbar pain syndromes, percutaneous four-contact electrodes were tested at levels from T-8 through T-12. At one or more levels, 46% of patients described paravertebral, nonradiating discomfort, unaccompanied by frequency-following muscle contractions. This was observed most commonly at the T-8 and T-9 levels. The effect was ameliorated in some cases by using multiple cathodes in parallel, which reduced the current density at individual contacts. In 10 of these patients, this side effect interfered with an otherwise successful trial to such a degree that an insulated plate electrode was selected for permanent implantation at the same level as the percutaneous electrode. This eliminated the uncomfortable side effect completely in all patients. Intraoperative testing with the insulated plate electrode inverted (that is, contacts dorsal) reproduced the side effect in the majority of patients, indicating that structures dorsal to the electrode, such as fibers in ligamentum flavum, mediate the effect. Postoperative testing by computerized techniques demonstrated improved coverage of pain by stimulation paresthesias, with lower stimulation power requirements, using the insulated plate electrode. This technical limitation of percutaneous spinal cord stimulation electrodes, which may confound treatment if unrecognized, has been found to have a straightforward solution which indicates the underlying mechanism.

Tremor and peripheral nerve entrapment. Case report.

A patient is described in whom pain, paresthesias, weakness, and resting tremor gradually developed 8 years after an ulnar nerve transposition. Electromyography revealed that the tremor occurred at 4 to 5 Hz, was abolished by voluntary muscle contraction, and was localized to ulnar-innervated muscles. Ulnar nerve conduction was focally slowed at the elbow; therefore, ulnar neurolysis was performed and a fusiform neuroma-in-continuity was found. Mechanically tapping the neuroma elicited repetitive discharges at 4 to 5 Hz in the intrinsic muscles of the hand; these discharges were abolished by anesthetic block proximal to the neuroma. Although the pain, paresthesias, and weakness were abolished by the neurolysis, the tremor persisted. Possible neurophysiological mechanisms underlying the appearance of tremor with peripheral nerve entrapment are discussed.

Microendoscopic posterior cervical laminoforaminotomy for unilateral radiculopathy: results of a new technique in 100 cases.

OBJECT: In this report the author presents surgery-related outcomes after application of a new technique. A posterior microendoscopic laminoforaminotomy was used for the surgical treatment of unilateral cervical radiculopathy secondary to intervertebral disc herniations and/or spondylotic foraminal stenosis. The results of this procedure are compared with those achieved using traditional laminoforaminotomy and anterior cervical discectomy with or without fusion. METHODS: One hundred consecutive patients who experienced unilateral cervical radicular syndromes, which were refractory to conservative therapy, and in whom imaging studies had confirmed lateral canal or foraminal compression, underwent surgical treatment. An endoscopy-assisted posterior laminoforaminotomy was performed using a microendoscopic visualization system for removal of herniated disc and foraminal decompression while the patient was in the sitting position. Excellent or good results were obtained in 97 patients. who returned to their preoperative employment and baseline level of physical activity. One patient returned to work but was unable to perform at baseline level; two patients returned to prior sedentary work but continued to have some activity-related pain and paresthesias. Two patients reported experiencing intermittent paresthesias or numbness, but this did not limit their activities. There were two cases of dural punctures, one case of superficial wound infection, and no deaths. CONCLUSIONS: The microendoscopic posterior laminoforaminotomy is an effective alternative for the treatment of unilateral cervical radiculopathy secondary to lateral or foraminal disc herniations or spondylosis. In this group of patients, it is preferable because it does not require the sacrifice of a cervical motion segment, has a low incidence of complications, and is associated with a much quicker return to unrestricted full activity than that obtained with other techniques.

Overdose of vincristine: experience with a patient.

Vincristine, referred to as a vinka alkaloid, has been used as a component of the various chemotherapeutic regimens. The major side effects of the usual dosage of vincristine are bone marrow suppression, gastrointestinal disorder, and neurotoxicity. A 53-year-old cervical cancer patient received 14 mg (4 mg/m2/day for 2 days) of vincristine instead of vinblastine because of the similarity between the two names. Then life threatening toxicities including paresthesias, bone marrow depression, severe oral mucositis, paralytic ileus, bladder atony, myalgia, muscle weakness, high fever, derangements of various organs (liver, heart), hypertension, and insomnia were encountered. But hypotension and syndrome of inappropriate secretion of antidiuretic hormone (SIADH) were not observed. Other than paresthesias in the extremities, the patient recovered completely from toxic impairments with intensive symptomatic and supportive care. In order to prevent the administration of the overdosed drug, it would be advisable for chemotherapy to be administered only by an experienced physician who is able to check the dose and concentration.

[Late results after surgical treatment of carpal tunnel syndrome. A clinical follow-up study of 60 cases].

In a follow-up study 60 hands of 49 patients were examined 1-12 years after operation for carpal tunnel syndrome. The syndrome was diagnosied in the majority of cases on clinical examination only. Paresthesia, hypesthesia or anesthesia in the 3 1/2 radial fingers of the hand are typical signs. Some patients complained of severe pain irradiating towards the elbow and shoulder. The method of surgical treatment is described in detail. Of the 49 patients only 2 were dissatisfied with the result. Both patients suffered from stenosing arteriosclerotic disease of the peripheral arteries of the hand and their pain and paresthesia were relieved by thoracic sympahtectomy. 58% of patients had complete relief from from symptoms while the remaining cases had a significant reduction of symptoms and were satisfied with the result of surgical treatment. The results were better in those patients who were operated on soon after the onset of symptoms. From the results of this study it is clear that surgical treatment of carpal tunnel syndrome provides good results and that surgical treatment should be recommended without delay if conservative treatment is unsuccessful.

[Hysteria and psychosomatic disorders in Portuguese immigrants].

Seventy patients presenting symptoms of hysteria (49 women and 21 men) were selected among patients observed at the Institute Minkowska during the year. This work is part of a research work on socio-cultural and environmental factors which can change mental status of immigrants. These are all portugese workers presenting for the first time atypical mental troubles called by the author: "bastard hysterical syndrome of the immigrant" and characterized partly or totally by the following symptoms: fatigue, anxiety, sense of suffocation, dyspnea, coughing, unilateral chills or generalized chil, abdominal or gastric pains, headaches and "diffused pains", paresthesia, aching back, tears and sorrow, fear of dying or having a cancer, asthenia, leg paresthesia and contractions, vomiting, diarrhea, cardiac pains, palpitations, dizziness and collapsing. These troubles appear sometimes without apparent motives but they are almost always due to a precipitating cause expressed by the patient: a delivery, a familial death, a homosexual proposition, a trauma without importance, a working conflict etc... But the most frequent cause invoked is "the french climate" without knowing precisely what the word "climate" means: atmospheric conditions, athmosphere or reception milieu? This latest interpretation seems more likely after months of psychotherapy. Most patients are not french speaking and cannot write; their origin is rural (familial villages well structured regarding their food and sexual economy), and people well "armed" by a system of defense mechanisms and well adopted conditioned reflexes. In this work, hysteria of the portugese immigrant is compared to childhood hysteria. As the hysterical burst of the child is aimed at calling attention, love of the mother, at finding a solution to a familial or social conflict, the hysterical burst of the immigrant is aimed at the absent family or at its substitutes, the bos, social security, the doctor. Furthermore, the attitude of the hosting Country--wanting and rejecting--is very ambivalent; "tenderness" at the time of reception, followed by indifference. Early attentions are followed by constant interdictions (threat of unemployment, false statements on sexual dangers of the immigrant etc;..). The immigrant, like the hysterical child, is periodically controlled (work and visit cards), supervised (supervisors), The narcistic satisfactions of being called a good worker can be followed by threats of firing in economic crisis. The society of the hosting country requires the immigrant to be identical to this society: language, physical appearance, food. The real paradoxical situation to which the immigrant is confronted and the real or hypothetical fears constitute conditions of experimental neurosis, to which portugese immigrants react very often by a bastard symptomatology of hysterical type, characteristic of displaced man. These preliminary studies are the frame for a future epidemiological survey in this specific population.

[A possibility of central diffusion during stellate ganglion blockade: "the sheath of the spinal rachidian nerve"].

Stellate ganglion block is a common treatment for neuropathic pain. The technique is not without potentially severe complications when a paratracheal approach is used. A 33-year-old woman complained of atypical facial pain of 15 years' duration with pain intensity of 6 to 8 on a visual analog scale and no pain-free periods upon use of inadequate analgesia. One minute after performing a second stellate ganglion block the patient showed signs of apnea and paralysis of the upper extremities and face, with no involvement of oculomotor muscles or the lower extremities, and no loss of consciousness. Assisted ventilation was started. Signs and symptoms resolved fully after 15 minutes. A few days later, the patient reported having perceived paresthesia in the affected zone during the procedure. Central spread of a portion of local anesthetic by way of the spinal nerve sheath toward the subarachnoid space may cause partial cervical and basal nuclear blockade. Signs would be apnea, involvement of the upper extremities and facial muscles, although paresthesia during the injection is the only evidence supporting this hypothesis. Bone contact and negative aspiration while performing a stellate ganglion block do not guarantee avoidance of complications.

Axillary block complicated by hematoma and radial nerve injury.

BACKGROUND AND OBJECTIVES: Hematoma is typically cited as one mechanism of nerve injury following axillary block. However, documented cases of this are lacking. METHODS: A healthy 38-year-old man was scheduled for surgical removal of a tumor of the hand. A transarterial axillary block was performed with a 22-gauge short-bevel needle using 40 mL of a mixture of equal volumes of 1.5% lidocaine and 0.5% bupivacaine containing 1:200,000 epinephrine. No paresthesias were reported. Postoperative, the patient developed a large axillary hematoma accompanied by paresthesias and radial nerve weakness. RESULTS: With conservative management, nerve recovery was complete in 6 months. CONCLUSIONS: Hematoma complicating axillary block may result in nerve dysfunction.

[Disappearance of essential tremor after thalamic infarction].

Stereotactic thalamotomy has been used with some benefit in the treatment of essential tremor. We report a 73-year-old woman whose essential tremor of the right hand spontaneously disappeared after thalamic infarction. She had suffered hand tremor of the right hand for seven years. One morning, she noticed mild muscular weakness in her right upper and lower extremities, numbness around her mouth and paresthesia in her right arm. Simultaneously, she noticed disappearance of the tremor of her right hand. Several days later, right hemiplegia and paresthesia completely resolved. Neurological examination revealed no postural tremor or resting tremor. T 2-weighted brain MR imaging showed a high-intensity signal in the left thalamus that involved the ventralis intermedius nucleus. Clinical recovery from the effect of the infarct on essential tremor was complete. Therefore, it seems that thalamic infarction in this patient had an effect on essential tremor similar to that achieved with thalamotomy.

[A case of bilateral brachial plexopathy after median sternotomy].

A 53-year-old man with bilateral brachial plexopathy after median sternotomy for cardiac surgery was described. When he was awakened six days after cardiac surgery, he experienced weakness and paresthesia of both upper limbs. Neurological examination revealed moderate to severe atrophy and weakness of right biceps, brachioradialis, left triceps, and distal muscles of both upper limbs, and paresthesia around the right thumb and the left hypothenar. Deep tendon reflex of the right biceps, triceps, brachioradialis and left triceps was absent. In addition, he showed Horner's syndrome at the left side. The results of needle EMG and nerve conduction study indicated the damage of the right upper trunk and left middle and lower trunks of the brachial plexus. Although brachial plexopathy following median sternotomy has previously been reported in Western literatures, there is only a single report of unilateral brachial plexopathy in Japan. This is the first report in Japan of the bilateral brachial plexopathy following median sternotomy, and suggests that brachial plexopathy should be recognized as a complication of median sternotomy.

[Prognostic value of preoperative electromyography for outcome of lumbosacral radiculopathy of discal origin].

OBJECTIVES: To assess the prognostic value of preoperative electromyography (EMG) for long-term outcome in patients who undergo surgery for discal radiculalgia at the lumbar level. PATIENTS AND METHODS: Thirty-seven patients who underwent surgery less than 6 weeks after the EMG were selected among a pool of 384 patients suffering from discal radiculalgia at the lumbar level who had had an EMG at our hospital since 1980. Among these 37 patients, 30 were contacted by telephone for an interview on outcome after a mean 42.1 +/- 22 month follow-up. RESULTS: Five out of 30 patients reported limitation for walking, 8/30 motor weakness, 14/30 had sensorial deficits, 12/30 had frequent or incapacitating radiculalgia, and 16/30 reported paresthesia. Patients were more satisfied with pain outcome (good or very good results in 22/30 patients (73%)) than with functional outcome (good or very good results in 20/30 patients (66%)). Preoperative EMG abnormalities (observed in 22/30 cases) were not correlated with patient age or duration of sciatica. The patients whose preoperative EMG was abnormal did not later report more paresthesia (11/20 versus 5/10) or severe radiculalgia (7/20 versus 5/10) than the others. Conversely, they complained more frequently of motor weakness (7/20 versus 1/10), but their global opinion about long-term outcome of surgery was not worse good or very good results for 15/20 patients with abnormal EMG (75%) versus 7/10 (70%) of those whose preoperative EMG was normal. CONCLUSION: This study shows that a normal EMG does not preclude surgical cure of discal sciatica. The results of preoperative EMG do not predict the long-term outcome after surgery: indeed they are only correlated with motor weakness (7/20 versus 1/10), but not with residual pain and functional outcome.

Diffuse large B-cell lymphoma associated with skin, muscle and cranial nerve involvement.

The present case, a 75-year-old man with extranodal B-cell lymphoma showed facial hemiplegia, paresthesia and cutaneous manifestations. He was initially diagnosed as having a facial paralysis of unknown etiology. One month after the original diagnosis, erythematous indurated plaques developed on his left cheek and nose. A skin biopsy from the plaque on his cheek showed dense infiltrates of large lymphocytes with irregularly shaped nuclei and prominent nucleoli in the dermis and subcutaneous tissue. The lymphocytes were positive for L26 and CD79a. A diagnosis of diffuse large B-cell lymphoma was made. A muscle biopsy from facial muscle in the area of the erythematous plaque showed massive destruction of the muscle tissues by the lymphomatous infiltrates. Furthermore, electrodiagnostic study showed peripheral cranial nerve palsies, involving the left facial and trigeminal nerves. We conclude that diffuse large B-cell lymphoma may develop symptoms such as facial hemiplegia and paresthesia prior to cutaneous manifestations. Diffuse large B-cell lymphoma must be considered as one of the important causes of palsies of cranial nerves at the peripheral level.

Selective serotonin reuptake inhibitor discontinuation syndrome: proposed diagnostic criteria.

OBJECTIVE: To establish specific criteria by which selective serotonin reuptake inhibitor (SSRI) discontinuation syndrome may be identified. DATA SOURCES: MEDLINE and PSYCHLIT databases were searched for case reports published from 1986 to 1997 inclusive, and references of relevant articles were also searched. STUDY SELECTION: Forty-six case reports of symptoms following the discontinuation of fluoxetine, fluvoxamine, paroxetine or sertraline were selected. Three studies of SSRI discontinuation were also reviewed. DATA EXTRACTION: Demographic and treatment information, as well as the timing, duration, number, nature and frequency of dicontinuation symptoms. DATA SYNTHESIS: Paroxetine was most frequently implicated. The drug had been tapered in half of the cases. In some cases, symptom onset began during taper, whereas, in most cases, symptoms began within 1 to 3 days of drug discontinuation. Fifty-three different symptoms were reported, with dizziness being the most common. Other common symptoms were nausea or emesis, fatigue, headache, gait instability and insomnia. Shock-like sensations, paresthesia and visual disturbances were the most rare. Without intervention, symptoms persisted for more than a week in half of the cases. In cases in which the SSRI was restarted, symptoms resolved within 72 hours. In some cases, withdrawal symptoms recurred when the same SSRI was again discontinued. CONCLUSIONS: Findings were used to construct diagnostic criteria for the SSRI discontinuation syndrome. These criteria are 2 or more of the following symptoms developing within 1 to 7 days of discontinuation or reduction in dosage of an SSRI after at least 1 month's use, when these symptoms cause clinically significant distress or impairment and are not due to a general medical condition or recurrence of a mental disorder: dizziness, light-headedness, vertigo or feeling faint; shock-like sensations or paresthesia; anxiety; diarrhea; fatigue; gait instability; headache; insomnia; irritability; nausea or emesis; tremor; and visual disturbances.

Transcatheter embolization of mycotic aneurysm of the subclavian artery with metallic coils.

Mycotic aneurysms of the subclavian artery are rare. This report describes an experience of 2 rare cases in which transcatheter embolization with metallic coils was performed for the management of these lesions alternative to surgery. Two patients who had been treated with chemotherapy for malignant neoplasms were diagnosed as having mycotic aneurysms of the left subclavian artery. The causes of these lesions were presumed to be the invasion of the arterial wall by the pulmonary abscess in case 1, and wound infection after placement of the reservoir for intraarterial chemotherapy in case 2. In both cases, proximal and distal sites of the aneurysm were embolized with metallic coils. In case 1, the vertebral artery was also embolized with Guglielmi detachable coils to avoid retrograde blood flow. Both aneurysms were completely occluded by a single embolization. In case 1, although weakness and paresthesia of the left hand remained, lethal hemoptysis due to aneurysmal fistulization to the lung parenchyma ceased. In case 2, no neurological deficit except for mild paresthesia in the left thumb had been observed. Both patients died of primary disease 10 and 5 months after the procedure. Transcatheter embolization is technically feasible and effective enough to treat the mycotic aneurysm of the subclavian artery even in the situation in which the surgical option seems to be difficult or risky.
