The aim of this paper is to demonstrate the unusual MR features of thoracic syringomyelia following TB meningitis and to discuss the neurosurgical aspect of the treatment of this rare entity. Four years after a TB meningitis episode, a 30 year-old female patient developed a progressive spastic paraparesis. MR studies revealed multiloculated syrinxes throughout the thoracic cord. She had a syringo-subarachnoid shunt with a silastic "T" tube inserted. On the first postoperative day, she showed a dramatic neurological improvement, but unfortunately her paraparesis progressed to the preoperative level within a month despite diminished size of the syrinxes on the control MRI examination. Two and a half years after the operation the patient complained of having a burning type of central pain, and further deterioration in neurological function. Thoracic spinal MRI examination demonstrated enlarged syringomyelic cavities. At the second operation syringo-peritoneal shunt insertion was performed via right T10-11 hemilaminectomy using a "T" tube. At present, 4 months after the second operation, the patient's neurological examination demonstrated decreased spasticity, and improved strength in the legs compared to the preoperative level. MRI is the first choice of investigation in detecting TB related myelopathy as it provides a greater detail of pathological changes within and around the spinal cord such as syrinx formation and arachnoiditis. The MR findings are also helpful in deciding the management and predicting the outcome. Presence of multifocal loculations and arachnoid adhesions is the likely cause of treatment failures and poor prognosis.

We report the case of a young woman who presented with a 2-month history of severe abdominal and pelvic pain. The past history was significant for a fall from a bicycle 1 week before the onset of her pain. Physical examination was remarkable for periumbilical tenderness. Work-up including pelvic sonogram and diagnostic laparoscopy suggested endomyometritis. The pain was minimally relieved by nonsteroidal anti-inflammatory drugs and narcotic analgesics. Thoracic spine magnetic resonance imaging (MRI) revealed a large disk herniation at the T9-10 level compressing the spinal cord. The patient subsequently underwent T9-10 diskectomy and laminectomy with dramatic relief of her symptoms. Postoperative rehabilitation hastened her functional improvement. This is a rare case of symptomatic thoracic disk herniation after trauma presenting as abdominal and pelvic pain. Physicians should be aware of this unusual presentation of thoracic disk herniation to avoid invasive diagnostic procedures.

In 1961, some 7 months after starting anaesthesia in the Leeds General Infirmary, I took out a subscription to the British Journal of Anaesthesia. It cost Pound Sterling3.15s.0d (Pound Sterling3.75) a year. The publishers John Sherratt and Son of Altringham) sent me the back numbers from the start of that year. I first had a paper published in the journal in 1965; first refereed a paper in 1969; joined the editorial board in 1975; and lasted there until 1998. The following account of the early years of the journal derives from the journal itself, and from records, letters and minutes of meetings kindly given to me by Dr Edmund Riding and Professor Andrew Hunter when they demitted offices with the journal. The history cannot be complete. Sadly, the earliest minutes books are lost. But there is much of interest covering the times when anaesthesia developed from the rag-and-bottle inhalation era to the use of intravenous anaesthetics, neuromuscular blocking agents, ventilators and monitoring. Thoracic and neurosurgical anaesthesia were revolutionized; cardiac surgery became possible; and resuscitation with intravenous fluids, blood and plasma all developed. Antibiotics improved care. Anaesthetists pioneered intensive care and latterly extended their roles in pain relief outside the operating theatre. All these developments have appeared in papers at some time in this journal. This is a personal view of the journal over its first 25 years: there will be errors and misinterpretations--these are mine.

Although radical resection is the best treatment for local aggressive benign tumors or malignant tumors of the spine, total spondylectomy for lower thoracic vertebrae may cause anterior spinal artery syndrome. There are few reports in the literature in which this syndrome has been documented in association with thoracic spondylectomy, although this syndrome is the most common neurologic complication after abdominal aortic surgery. A 50-year-old woman with a giant cell tumor of the thoracic vertebrae was treated by posterior and anterior surgery. Thoracic segmental arteries from T10 to T12 had to be resected bilaterally to dissect the aorta free from the tumor. After resection of all feeding arteries to the tumor, the tumor and entire parts of T10, T11, and T12 were removed. Postoperative neurologic examination disclosed flaccid paralysis of the lower extremities and sphincter incontinence. Although pain and temperature sensation were absent, vibration and position sense were intact, showing anterior spinal artery syndrome. Intraoperative somatosensory-evoked potential monitoring only showed that transient deterioration failed to adequately reflect this neurologic injury. Major reconstructive surgery involving lower thoracic regions may cause anterior spinal artery syndrome. Somatosensory-evoked potential monitoring might not reliably predict overall neurologic outcome involving the blood supply of the lower thoracic regions.

Besides the common distal symmetrical sensory-motor polyneuropathy (DSP) that is often associated with autonomic dysfunction, diabetic patients may develop multifocal sensory-motor deficits (MDN) secondary to roots, plexus and nerve trunk involvement. Nerve ischaemia has been suggested as a common mechanism for the different patterns of diabetic neuropathies, yet the important clinical differences that exist between DSP and MDN suggest concurrent factors. In order to learn more on the subject, we prospectively studied 22 consecutive diabetic patients with MDN, for which other causes of neuropathy were excluded by appropriate investigations, including biopsy of a recently affected sensory nerve. Three patients had a relapsing course, and the others an unremitting subacute-progressive course. Painful MDN progressed over 2-12 months. The neurological deficit predominated in distal lower limbs which were involved in all patients, unilaterally in seven, bilaterally in the others, with an asynchronous onset in most cases. In addition, a proximal deficit of the lower limbs was present on one side in seven patients, and on both sides in six. Thoracic radiculoneuropathy was present bilaterally in two patients, and unilaterally in one. The ulnar nerve was involved in one patient, and the radial nerve in two. The CSF protein ranged from 0.40 to 3.55 g/l; mean: 0.87 g/l. Electrophysiological testing showed severe, multifocal, axonal nerve lesions in all cases. Asymmetrical axonal lesions were found in all nerve specimens. The mean density of myelinated axons was reduced to 1340 +/- 1070 per mm(2) of endoneurial area versus 8370 +/- 706 myelinated fibres/mm(2) in controls. The mean density of unmyelinated fibres was reduced to 5095 +/- 6875 per mm(2) (extremes: 0-26 600). On teased fibre preparations, 34 +/- 31% of the fibres were at different stages of axonal degeneration (extremes 0-99%); 7 +/- 6% of the fibres showed segmental demyelination or remyelination. Necrotizing vasculitis of perineurial and endoneurial blood vessels were found in six patients. Endoneurial seepage of red cells was present in 11 specimens, and endoneurial haemorrhage in five. Ferric iron deposits that characterize previous bleeding were found in seven patients, including two who had no red cells in the endoneurium. Perivascular mononuclear cell infiltrates were present in the nerve specimens of 21 out of 22 patients, prominently in four patients. In comparison, nerve biopsy specimens of 30 patients with severe distal symmetrical diabetic polyneuropathy showed mild epineurial mononuclear cell infiltrate in one patient and endoneurial seepage of red cells in another. We conclude that MDN is related to pre-capillary blood vessel involvement in elderly diabetic patients with a secondary inflammatory response.

Spinal opioids are effective analgesics for surgical and non-surgical pain. Central and systemic side effects are less frequent than with epidural local anaesthetics or parenteral opioids. This review focuses on the analgesic efficacy of spinal opioids and their combination with local anaesthetics for postoperative analgesia, including patient-controlled epidural analgesia. Intrathecal administration of opioids has some advantages over their administration by the epidural route. Several factors may influence selection of the opioid; however, in most situations morphine is the drug of choice. Thoracic epidural administration of opioids seems to have no clinically important advantages over the lumbar route in terms of quality of analgesia, adverse effects, doses required or pulmonary function. However, evidence suggesting that effective postoperative analgesia can significantly improve postoperative morbidity in patients at risk is accumulating. In such patients, combined use of epidural local anaesthetics and opioids may become the technique of choice for postoperative analgesia. However, there is no evidence that this would have any clinically relevant benefit in low-risk patients.

Off-pump coronary artery bypass technique or bypass graft surgery without the use of a heart-lung machine has been introduced in the last six years, and now comprises approximately 25 per cent of all coronary artery bypass surgery being done in the world. One of the goals of beating heart surgery is to eliminate the complications associated with the use of cardiopulmonary bypass. The use of all arterial conduits for coronary artery bypass graft has become more acceptable after experiences gained and reports of better long-term results. From January 2001 to December 21 2002 the authors performed 251 off-pump procedures. One hundred and nine of these cases were done utilizing all arterial conduits. The data was stratified using the US National Society of Thoracic Surgeons Cardiac Surgery Database pre-operative risk module and divided into 3 groups as suggested: Low risk group with a predicted mortality of 0-1 per cent (2 patients); Medium risk group with a predicted mortality of 2-9 per cent (87 patients), and High risk group with a predicted mortality of 10+ per cent (10 patients). The predicted mortality of the entire group was 4.5 per cent. There were 90 males and 19 females with a mean age of 60.2 +/- 10.7 years, with 15.6 per cent of them older than 70 years. Pre-operative co-morbidities included 1/4 of the patients who had ejection fraction (EF) of equal to or less than 0.4, 4.5 per cent had unstable angina, 1.6 per cent had urgent/emergent status, 26.6 per cent underwent re-operative procedure, 1 per cent had pre-operative serum creatinine more than 2 mg per cent, 4.8 per cent had a history of stroke, 20.2 per cent had a history of congestive heart failure, 45.2 per cent had a history of previous myocardial infarction, 10.7 per cent had a history of chronic obstructive pulmonary disease, 46.9 per cent had a history of diabetes, 62 per cent had hypertension, and 20 patients (18.3%) required intra aortic balloon pump. Intra-operative parameters revealed 3.7 +/- 1.3 grafts/patient. The left internal mammary artery (LIMA) was used to the left anterior descending (LAD) in 6.4 per cent, or sequential with the diagonals 93.6 per cent. The 30 days mortality was 3.6 per cent (4 cases). Further analysis revealed that pre-operatively, none of these 4 cases was in the low predicted (predicted mortality of 0-1%) risk group, 2 of them were in the medium (predicted mortality of 2-9%) and the other 2 were in the high predicted risk (predicted mortality of 10+%) group. The skin-to-skin time was 4.1 hours and there were two conversions to on-pump in this group. Post-operatively, the intubation time was 4.7 hours. There was no peri-operative myocardial infarction, one patient required dialysis, and no patient experienced stroke. There was no sternal wound or arm wound infection, 9.5 per cent experienced temporal sensation impairment at the site of the radial artery harvesting at one month. Re-operation for bleeding occurred in 3 cases, and thirteen patients (14.3%) developed new atrial fibrillation. The authors are no longer making a one-foot long incision and spread ten inches wide like in the old days'. With the less invasive approach lessened in the recent past, the authors have found the less invasive the incision the less the pain after surgery. Totally eliminating the leg incision has allowed the patient to get up and mobilize on the same afternoon, if the procedure was done in the morning. All of these approaches combined with the off-pump technique, as far as the authors are concerned, will provide those who need coronary arterial bypass graft the best operative procedure.

Endoscopic Thoracic Sympathectomy (ETS) has gained an increasing popularity due to its minimal invasive character. Despite the simplicity of the procedure, non-surgical options should always be considered as the first line of treatment. The complication risk of ETS is low but side effects, primarily compensatory sweating (CS) of mainly the trunk may be severe enough to cause regret of the procedure. The risk/benefit ratio should always be discussed with the patient. Severe palmar hyperhidrosis and facial blushing respond very well to ETS with a high patient satisfaction rate. Facial hyperhidrosis is effectively treated with ETS but is associated with a high risk for severe CS. Axillary hyperhidrosis is best treated by other means than ETS. The use of ETS for pain syndromes, vascular insufficiency and angina pectoris is not well supported by scientific evidence, making mandatory careful patient selection.

A 31-year-old patient complained of severe crushing chest pain that radiated to his left arm and jaw. After admission to the hospital, tests revealed a normal electrocardiogram, normal treadmill, normal coronary arteriogram, and normal cardiac enzymes. However, the patient continued to have pain, which was relieved by sublingual and intravenous nitroglycerine. He was discharged from the hospital with a diagnosis of "musculoskeletal" chest pain, taking nonsteroidal anti-inflammatory drugs, muscle relaxants, and narcotics. Two weeks later, the patient returned with worsening symptoms. Cardiac work-up was again negative. Thoracic and cervical spine radiographs were ordered for possible discogenic pain. After abnormalities were found on cervical radiographs, magnetic resonance imaging (MRI) was ordered, and the patient was referred to an orthopedic surgeon. Further work-up revealed a herniated disk at C6-C7, with radicular pain. Surgery on the suspect disk totally relieved the patient's pain.

Cardiovascular infections due to Salmonella enterica are infrequently reported, so their clinical features, prognosis, and optimal treatment are not completely known. Mortality associated with aortitis and endocarditis caused by nontyphoidal Salmonella remains exceedingly high. In this review of cases of cardiovascular infections due to Salmonella enterica studied in 2 hospitals in Madrid, we tried to assess the clinical manifestations and the procedures leading to diagnosis in addition to treatment and outcome. To complete the spectrum of infections related to cardiovascular surgery, cases of postoperative mediastinitis, pericarditis, and infections associated with cardiac devices were also included.Twenty-three patients were reviewed: 11 had mycotic aneurysms; 7 had endocarditis; 2 had device-related infections; and 3 had pericarditis, mediastinitis, and infection of an arteriovenous fistula, respectively. The risk of endovascular infection in patients older than 60 years with bacteremia due to nontyphoidal Salmonella was 23%. Most patients with aortitis had risk factors for atherosclerosis, and 6 had preexisting atherosclerotic aortic aneurysms. All except 1 patient with endocarditis had underlying cardiac disorders. Acquired immunodeficiency disease (AIDS) was a major risk factor for salmonella bacteremia in 1 patient with aortitis and 1 with endocarditis. Fever, unremitting sepsis, "breakthrough" and relapsing bacteremia were the most common clinical findings. In addition, abdominal or thoracic pain and cardiac failure and pericarditis were common features in patients with aortitis and endocarditis respectively. Computed tomography (CT) scan, arteriography, and echocardiography were the main diagnostic tools. Mortality associated with mycotic aneurysms and endocarditis due to S. enterica was 45% and 28%, respectively. Thoracic aneurysms, rupture, and shock at the time of diagnosis were associated with increased mortality in patients with aortitis. In situ bypass grafting was successfully performed in most cases. After surgery, antimicrobial therapy was continued for 4-9 weeks. No relapses were observed after a mean follow-up of 64 months. Antimicrobial therapy alone or combined with valve replacement or excision of a ventricular aneurysm was successful treatment for most patients with salmonella endocarditis. Combined medical and surgical treatment was required for patients with mediastinitis and pericarditis, and patients with device-related infections needed removal of the complete device. Diagnosis of aortitis due to nontyphoidal Salmonella should be established as early as possible to reduce mortality. Patients older than 60 years who have positive blood cultures for Salmonella along with fever and back, abdominal, or chest pain should have an extensive workup for infective aortitis. Immediate bactericidal antimicrobial therapy should be started and a CT scan should be performed on an emergency basis. If a mycotic aneurysm is found, surgical resection should follow as soon as possible. Resection of the aneurysm with in situ bypass grafting is the procedure of choice. Postoperative antimicrobial therapy for 6-8 weeks seems enough to avoid relapses. Optimal treatment of patients with endocarditis occurring on ventricular aneurysms must include resection of the aneurysmal sac. Salmonella endocarditis can be successfully treated with antimicrobials alone. Valve replacement should be reserved for patients with cardiac failure or persisting sepsis, and for those who relapse after discontinuation of antimicrobial therapy.
