Intraspinal narcotic (usually intrathecal morphine) infusions with implanted pumps are increasingly used in patients with intractable chronic pain not caused by cancer. In some patients, pain control is difficult with infusions of morphine. Seven patients with diagnoses of arachnoiditis, epidural scarring, and/or vertebral body compression fracture were treated with alternative solutions in an epidural route. For maximal flexibility, Medtronic implanted programmable infusion pumps with catheters to T6-T10 were used, and pain was monitored by verbal pain scales. In three patients, epidural infusions of morphine in 0.5% bupivacaine (MS-MARC) resulted in little or no pain relief without significant side effects (e.g., headache, nausea, or vomiting). In these same patients, epidural infusions of sufentanil citrate resulted in pain scale reductions of 92%, 82%, and 40%, respectively, with no side effects. Four other patients found more effective pain relief when switched from initial sufentanil citrate infusions to MS-MARC. Pain scale reductions (with no side effects) were 92%, 76%, 59%, and 47% in these patients. Pain relief and minimal side effects with sufentanil citrate is theorized to result from its higher lipophilicity promoting local transdural diffusion to spinal cord and limiting upward diffusion to the brain stem. Sufentanil citrate is also advantageous for programmable pumps because it is 100 times more potent than morphine and therefore allows longer pump refill times and higher infusion doses. Although this study was done on a limited number of patients, sufentanil citrate and MS-MARC in epidural infusions using programmable infusion pumps for non-cancer patients provide significant alternative drug combinations and routes.

The common diagnoses in low back pain are lumbar strain, lumbosacral radiculopathy, osteoarthritis, degenerative disc disease, spinal stenosis, and sacroiliac joint dysfunction. Unusual causes of low back pain that have been previously identified include abdominal aortic aneurysms, pelvic neoplasms, and retroperitoneal hemorrhages. This report describes a case of back pain that was apparently caused by a duodenal ulcer. A 54-year-old man with no significant medical history presented with a complaint of mid to low back pain (T10-L2), which was diagnosed as joint dysfunction. A comprehensive treatment program was prescribed and the patient was instructed to return to clinic in 4 weeks. Three weeks later, he experienced a syncopal episode followed by coffee ground emesis. He immediately sought medical attention at an emergency room, where he was admitted to the hospital with a diagnosis of upper gastrointestinal bleed. Esophagogastroduodenoscopy showed a large duodenal ulcer, and the patient underwent vagotomy and pyloroplasty. He returned to his physiatrist's office 3 weeks after hospital discharge with minimal back pain. The cause of the back pain proved to be referred visceral pain from his duodenal ulcer. This case is presented to reemphasize the need to include the uncommon phenomena in the differential diagnosis of low back pain.

We report the results of a prospective Tunisian study using primary chemotherapy followed by conservative surgery in primitive limb osteosarcoma. From January 1988 to January 1998, 56 patients affected by limb osteosarcoma entered in a prospective study of neoadjuvant chemotherapy with the T10 protocol before surgery with a conservative intent. Initial work-up include: clinical exam with tumor measurements, chest and limb X-rays, limb CT-scan or MRI, chest CT-scan, bone scintigraphy and hematological and renal biological exams. Patients receive pre- and post-operative chemotherapy according to the T10 modified protocol. Fifty-six patients (33 M/23 F) with a mean age of 19 years (8 to 28) are included. Mean clinical and radiological tumor size is around 14 cm. Main histologic type is classic osteosarcoma (50% of cases) and 10 patients (9%) presented with initial metastasis; 42 patients on 56 receive the whole pre-operative protocol. Treatment is well tolerated excluding 18 episodes of mucositis, 29 of leucopenia (< grade 3), 7 of thrombopenia (< grade 3), 4 of cutaneous toxicity, 2 of pulmonary toxicity and 3 of nausea-vomiting. We observe 36% of good histological responders and 64% of bad responders to primary chemotherapy, 27 patients on 49 operated (53%) have a conservative surgery and 18 (47%) a radical surgery. With a median follow-up of 51 months (8 to 128), 29 patients remain alive free of disease (15/17 GR and 14/30 BR), 2 are alive with disease, 2 died by toxicity, 14 died by progressive disease and 9 are lost to follow-up with evolutive disease. Five year disease-free survival is 55% for the 46 non metastatic patients. In univariate analysis, seric alkaline phosphatase level (p = 0.0014) and histological response to chemotherapy (p = 0.0218) are significant factors for prognosis.

A 26-year-old administrative assistant presented with 3 years of left-hand dysesthesia involving primarily the first 3 digits. Her symptoms increased at night and with keyboard use. Through 12 visits to primary and specialty care physicians over 3 years, she experienced minimal improvement with splints and moderate improvement with gabapentin. On presentation, careful questioning revealed an abrupt onset of symptoms 3 years previously, related to a 2-week episode of gastritis associated with recurrent emesis. Examination revealed a negative Tinel sign over the median nerve at the wrist, decreased left biceps reflex, positive Spurling test, and decreased sensation over the palmar and dorsal surfaces of the left hand in the C5-6 distribution. The atypical onset of symptoms, poor response to therapy, and physical findings suggested the possibility of a radicular or central neurologic etiology for the patient's hand numbness. Magnetic resonance imaging demonstrated a Chiari I malformation with a syrinx extending from C2 to T10, with the greatest diameter at C4. Neurosurgical decompression led to a decrease in symptoms. A meticulous history and physical examination should be performed on patients with presumed carpal tunnel syndrome with an atypical onset of symptoms or response to therapy.

In this study we examined the onset times of sensory and motor block during epidural ropivacaine anesthesia with and without the addition of fentanyl to the epidural solution. Forty-five young male patients undergoing knee arthroscopic surgery were randomly allocated into 3 groups of 15 patients each: epidural fentanyl (EF; epidural administration of 15 mL of 1% ropivacaine plus 100 mug fentanyl followed by IV injection of 2 mL of normal saline); IV fentanyl (IF; epidural administration of 15 mL of 1% ropivacaine plus 2 mL of normal saline followed by IV injection of 100 mug fentanyl); and control (C; epidural administration of 15 mL of 1% ropivacaine plus 2 mL of normal saline followed by IV injection of 2 mL of normal saline). The sensory and motor blocks were assessed by pinprick and modified Bromage scale, respectively. The hemodynamic changes, postepidural shivering, and side effects of epidural fentanyl were also recorded. There was no difference in the distribution of age, weight, and height among the 3 groups. The onset time of sensory block to the T10 dermatome was significantly more rapid in the EF group (13.0 +/- 3.0 min) than in the IF group (16.2 +/- 3.5 min, P < 0.05) or C group (17.7 +/- 3.6 min, P < 0.05). The onset times of motor block up to Bromage scale 1 and 2 were significantly more rapid in the EF group (11.9 +/- 4.6 and 24.4 +/- 5.9 min) than in the IF group (16.9 +/- 4.7 and 30.8 +/- 5.6 min, P < 0.05) or C group (18.3 +/- 4.9 and 32.7 +/- 5.7 min, P < 0.05). There was no difference in the incidence of shivering among the three groups. Pruritus was observed in three patients of the EF group and one patient of the IF group. No nausea, vomiting, respiratory depression, urinary retention, or hypotension was observed in any patient. We conclude that epidural administration of the mixture of 100 mug fentanyl and 1% ropivacaine solution accelerated the onset of sensory and motor blocks during epidural ropivacaine anesthesia without significant fentanyl-related side effects.

Serial changes in the circulating and cerebrospinal fluid (CSF) cytokine levels were assessed in a patient with Sjogren's syndrome (SS)-associated meningoencephalomyelitis. A 16-yr-old girl diagnosed as having primary SS at 8 yr of age presented headache and vomiting. CSF studies revealed lymphocyte-dominant pleocytosis and high IgM index, but no evidence of infection. Disturbed consciousness and diffuse slow waves on electroencephalogram led to the diagnosis of SS-meningoencephalitis. The clinical condition subsided after a cycle of dexamethasone therapy, however, 2 months later urinary retention and paresthesia of the lower body developed. Craniospinal magnetic resonance imaging (MRI) showed extensive intraparenchymal lesions with high T2-weighted signal intensity adjacent to the posterior left horn of lateral ventricle of the brain and the longitudinal lesion from C5 to T10 of the spinal cord. High-dose methyl-prednisolone and subsequent tacrolimus therapy has effectively controlled the activity of SS-meningoencephalomyelitis. Monitoring of systemic and CSF cytokine levels during the course of illness revealed that CSF interleukin-6, but not interferon-gamma or tumor necrosis factor-alpha levels were the sensitive indicator of disease activity. The unique cytokine profile, differing from those of infectious meningitis may be useful for predicting the central nervous system involvement in autoimmune disease.

Anticancer agents such as cisplatin stimulate nausea, vomiting, and behaviors indicative of malaise. Rats and mice, and probably all rodents, do not possess a vomiting response, and their ingestion of kaolin clay (a pica response) has been used as an index of malaise. Similar to the action of cisplatin on emesis in vomiting species, in the rat cisplatin activates vagal afferent fibers, and cisplatin-induced kaolin intake is largely dependent on an intact abdominal vagus. Cisplatin also stimulates Fos expression in the rat brain in areas known to play a role in emesis in other species, but it is not known whether vagal input is required for this CNS activation. In the present study, rats were given abdominal vagotomy or sham operation to test the role of an intact vagus on cisplatin-induced Fos expression 6 h after injection with saline or cisplatin (6 mg/kg, ip). Cisplatin treatment produced Fos expression in the area postrema and multiple levels of the nucleus of the solitary tract (NTS) of sham-operated rats. Vagotomy reduced cisplatin-induced Fos expression in the caudal and middle levels of the NTS and central amygdala. Furthermore, cisplatin did not significantly alter Fos expression in the spinal cord (T8-T10) before or after vagotomy. These results suggest that a defined portion of cisplatin-induced Fos expression is dependent on vagal input, with a majority of this response determined by either direct action of cisplatin or humoral factors on the CNS.

Modern imaging has revealed that thoracic disc herniation (TDH) has a prevalence of 11-37% in asymptomatic patients. Pain, sensory disturbances, myelopathy, and lower extremity weakness are the most common presenting symptoms, but other atypical extraspinal complaints, such as gastrointestinal or cardiopulmonary discomfort, may be reported. Our objective is to make providers familiar with TDH's atypical symptoms to help avoid potential serious consequences created by a delay in diagnosis. We report the cases of two patients who each presented with atypical extraspinal symptoms secondary to a TDH. One patient presented with a chronic history of nausea, emesis, and chest tightness and MRI showed a large right paramedian disc herniation at T7-8. A second patient reported chronic constipation, buttock and leg burning pain, gait instability, and urinary frequency; an MRI of his thoracic spine demonstrated a central disc herniation at T10-11. TDH can present with vague extraspinal symptoms and unfamiliarity with these symptoms can lead to misdiagnosis with progression of the disease and unnecessary diagnostic tests and medical procedures. Therefore, TDH should be included in the differential diagnosis of patients with negative gastrointestinal, genitourinary, and cardiopulmonary system basic studies.

A 45-year-old man noted a tendency to fall to the left side on standing following headache and vomiting. Neurological findings were unremarkable except for truncal lateropulsion to the left side. Brain magnetic resonance imaging (MRI) showed a small infarct in the left inferolateral part of medulla. Clinical and imaging findings suggested vertebral artery dissection as the cause of stroke. On hospital day 6, the patient developed decreased pain and temperature sensation in the right side below T10 sensory level and decreased sweating on the left side of the face with miosis of the left pupil. Brain MRI revealed an expanded lesion of the left inferolateral part of medulla. In our patient, the involvement of the spinocerebellar tract and the lateral spinothalamic tract likely contributed to the development of truncal lateropulsion and sensory disturbance below thoracic levels, respectively. Our case is clinically important in understanding a correlation between clinical symptoms and lateral medullary lesions.

Remote cerebellar hemorrhage after cranial and spinal surgeries is a well-documented entity, so far concomitant supra- and infra-tentorial hemorrhage after spine surgery has rarely been reported in the literature. A 57-year-old woman presented with intractable low back pain and severely impaired mobility. One year ago, she underwent lumbar laminectomy and fusion with posterior spinal instrumentation between L2 and S1. She developed adjacent segment disease at the upper level of the instrumented vertebra. She had a revision surgery and underwent posterior laminectomy and fusion with bilateral transpedicular instrumentation between T10 and S1. She had severe headache, somnolence, and left hemiparesia 48 h after the surgery. Her emergent head computed tomography depicted intra-parenchymal hemorrhage in the right parietal lobe accompanying with subarachnoid hemorrhage, bilateral symmetrical cerebellar hemorrhages and pneumocephalus. She was treated nonsurgically and she got better despite some residual deficits. Symptoms including constant headache, nausea, vomiting, impaired consciousness, new onset seizure, and focal neurological deficit after spine surgeries should raise suspicion for intracranial intra-parenchymal hemorrhage.
