Spinal tuberculosis is usually secondary to lung or abdominal involvement and may also be the first manifestation of tuberculosis. Spinal tuberculosis (often called Pott's disease) is by definition, an advanced disease, requiring meticulous assessment and aggressive systemic therapy. Physicians should keep the diagnosis in mind, especially in a patient from a group with a high rate of tuberculosis infection. This review aims on updating the knowledge on spinal tuberculosis and its management. Skeletal involvement has been reported to occur in approximately 10% of all patents with extrapulmonary tuberculosis, and half of these patients develop infection within the spinal column. Symptoms of spinal tuberculosis are back pain, weakness, weight loss, fever, fatigue, and malaise. It is much more prone to develop neurological manifestation, paraplegia of varying degree. The palpation of spinous process in routine clinical examination is the most rewarding clinical method and is an invaluable measure for early recognition. Diagnosis of spinal tuberculosis is made on the basis of typical clinical presentation along with systemic constitutional manifestation and the evidence of past exposure to tuberculosis or concomitant visceral tuberculosis. Magnetic resonance imaging can define the extent of abscess formation and spinal cord compression. The diagnosis is confirmed through percutaneous or open biopsy of the spinal lesion. Surgery is necessary as an adjunct to antibiotic therapy if the vertebral infection produces an abscess, vertebral collapse, or neurologic compression. Some patents need aggressive supportive care owing to tuberculous meningitis or encephalopathy. Moreover, the importance of immediate commencement of appropriate treatment and its continuation for adequate duration along with the proper counseling of the patient and family members should not be underestimated for successful and desired outcome.

We report the anesthetic management in two infants who were a three-month-old boy (case 1) and a two- month-old girl (case 2), undergoing hemilaminectomy for giant mediastinal neuroblastoma. Neuroblastoma invades into the intrathecal space in a rare occasion, resulting in paraplegia, which requires emergent operation to save the spinal cord. Mediastinal neuroblastoma also possesses significant respiratory and cardiovascular risks due to the close anatomic relationship with vital organs. In the present report, we show that preoperative computed tomography (CT) scan and/or echocardiography revealed tracheal deviation in case 1 and mass compression of the left atrium in case 2. Therefore, the patients with mediastinal masses should be carefully evaluated before subjecting them to anesthesia. Especially, there is a possibility that the masses which do not appear to compress the airway and cardiovascular systems develop the airway obstruction and cardiovascular collapse after induction of general anesthesia. In fact, before induction of general anesthesia in the case 2, trial of the prone positioning which was scheduled for the hemilaminectomy, resulted in bradycardia and hypotension, presumably due to the compression of the left atrium. In summary, the authors here discussed the preoperative evaluation and anesthetic management for giant mediastinal neuroblastoma in infants.

Patients with Morquio syndrome can develop respiratory failure secondary to reduced chest wall compliance and airway collapse from irregularly shaped vocal cords and trachea. We report the case of a patient with Morquio syndrome whose clinical course was complicated by tracheomalacia. An obese 29-year-old female with Morquio syndrome presented with severe wheezing and tachycardia. One month prior to admission, she underwent elective spinal stabilization surgery, which resulted in fixed head flexion. The surgery was complicated by paraplegia and the need for mechanical ventilation via tracheostomy. Initial bronchoscopy revealed severe tracheomalacia, and the tracheostomy tube was changed to one with an adjustable flange. On 3 occasions over the next 20 days she had labored breathing with dramatically decreased V(T). Each time, bronchoscopy revealed almost complete occlusion of the distal end of the tracheostomy tube. Ventilation became much easier when the tracheostomy tube was advanced past the obstruction. After one month, she became febrile, severely hypoxemic, and her family decided to withdraw care. In patients with Morquio syndrome, close attention must be given to the patient's abnormal airways and malformed chest cage. Mechanical ventilation may be difficult because of upper-airway obstruction or low compliance imposed by the restrictive chest wall. Complete tracheal collapse can occur in these patients, especially with fixed head flexion.

Multiple myeloma is a hematopoetic disorder and multicentric disease, with the most common localisation being the spine. A 47-year-old male presented with progressive paraplegia, superficial and deep sensory disturbance below the level of T4. Spinal magnetic resonance image showed an epidural mass compressing the spinal cord at the level of T4-T6 with intact bone structure. The patient underwent surgical T4-T6 posterior spinal decompression. Microscopic examination and immunohistochemical studies confirmed the diagnosis of multiple myeloma of kappa subtype. Immunoelectrophoresis revealed the presence of immunoglobulin G kappa. The patient was subsequently started on steroids and chemotherapy for myeloma. Extraosseous epidural tumors causing compression myelopathy without evidence of destruction or collapse of vertebral bodies are relatively rare; to our knowledge only four cases have been reported in English literature.

Pilomatrix carcinoma, the malignant equivalent of pilomatrixoma, is rare among skin cancers. In the literature, there have been 80 cases of pilomatrix carcinoma reported, and among them nine were with metastases. The clinical presentation of this case is suggestive for the biology and of the usual history of this neoplasm. The patient was a 53-year-old male who had been treated 2 years earlier for a pilomatrix carcinoma located in the posterior part of the neck. The clinical presentation had been characterised by sudden paraplegia caused by vertebral collapse at T4 due to bone metastases. The patient underwent a first surgery for vertebral stabilisation and medullary decompression; then, he had a second operation for the resection of the local relapse of the tumour. Literature review and analysis of this case show that the pilomatrix carcinoma should be regarded as a highly locally aggressive tumour, with a high rate of local recurrence as well as metastases.

Hodgkin disease is a nodal disease. Spinal cord or root compression is a rare complication and usually seen in the setting of progressive, advanced disease. We report 2 cases of Hodgkin disease in pediatric patients who presented with neurologic signs. One patient had paravertebral masses and involvement of thoracic vertebrae, which was initially misdiagnosed as spinal tuberculosis. The second patient who presented with paraplegia and bladder and bowel involvement had an epidural mass with collapse of thoracic vertebra. Lymph node biopsy revealed Hodgkin disease, mixed cellularity in both the cases. Both were treated with chemotherapy followed by radiotherapy.

Acute traumatic aortic injury is a life-threatening entity that requires emergent treatment. Treatment was once performed with left thoracotomy, resection of the damaged aortic segment, and placement of an interposition graft. Within the past decade, endovascular therapy has gained increased acceptance, primarily because of a significant decrease in mortality and morbidity compared with those of surgery. The authors reviewed the experience with management of acute traumatic aortic injuries at their institution, as well as that reported in the literature. Complications after endovascular repair include endoleak, endograft collapse, stroke, upper extremity ischemia, paraplegia, graft infection, endograft structural failure, missed injury or stent migration, and access site complications. After surgical repair, paraplegia and ischemia to other organs, graft dehiscence, graft infection, and graft stenosis may occur. With the growing use of endovascular management of acute traumatic aortic injuries and the increased likelihood of patient survival, the radiologist will be expected to be familiar with the findings in these patients and is positioned to play a critical role in early recognition of potential complications. Early diagnosis of the complications of therapy for aortic injury is imperative for reduction of mortality and morbidity.

In veterinary medicine, serum creatine-kinase (CK) activity is mostly used to assess skeletal muscle damage. This retrospective study aimed to evaluate the prevalence of increased CK activity in a large, ill-cat population and to characterise associated diseases, clinical and laboratory findings and its prognostic value. Cats with a complete serum biochemistry analysis were consecutively enrolled, divided into two CK activity-based groups (within and above reference interval) and compared. The study included 601 cats. Median serum CK was 402 U/l (range 16-506870). Increased CK (>250 U/l) was observed in 364 (60%) cats, and>30-fold its upper reference limit in 43 (7%). Cats with increased CK had greater (P < or = 0.05) body weight, and were more likely to have a history of collapse, dyspnoea, abnormal lung sounds, cyanosis, shock and paraplegia, higher median serum alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase activities and total bilirubin and triglyceride concentrations, but lower, median total protein, albumin, globulin and cholesterol concentrations and proportion of anorexia than cats with normal CK. Cardiac diseases, trauma, bite wounds, systemic bacterial infections, prior anaesthesia and intramuscular injections were more common (P < or = 0.05) in cats with increased compared to normal CK activity. The hospitalisation period was longer (P=0.007) and treatment cost and mortality were higher (P<0.005) in cats with increased CK activity. However, CK activity was an inaccurate outcome predictor (area under the receiver operator characteristics curve 0.58). Increased CK activity is very common in ill cats.

Endovascular intervention has emerged as a less traumatic alternative treatment for several diseases of the thoracic aorta.(1,2) However, depending on the different aortic pathologies, procedure related complications have become increasingly evident: severe complications include type I endoleaks, migration, and endograft (EG) collapse, as well as those observed during conventional surgery (eg, stroke and paraplegia).(3,4) One of the emerging and most alarming complication of thoracic endografting is iatrogenic retrograde type A acute dissection (RTAAD).(5) Retrograde type A acute dissection is defined as acute aortic dissection that originates distally to the ascending aorta with a retrograde flap progression into the ascending aorta.(6) This complication has been previously described during conventional cardiac surgery with high mortality rate; previous case reports suggested that the fragility of the aortic wall and Marfan disease were predisposing factors to such a life-threatening complication.(7-9) This report presents a case of iatrogenic RTAAD after EG repair of a descending thoracic penetrating aortic ulcer, requiring emergent surgical replacement of the ascending aorta and the aortic arch. The available English literature on RTAAD was also reviewed, in order to recognize potential predisposing factors and specific strategies to prevent it.

A-76-year old woman was admitted to the hospital with paraplegia after a collapse at home. Magnetic resonance imaging showed white matter lesions from Th4 to L2 as well as large confluent white matter lesions in the cerebrum. Within 3 days, the patient's mental status decreased dramatically and she finally died on day 16 after her fall. Autopsy examination revealed an acute myeloid leukemia, which had not previously been diagnosed and which had never been treated. In the CNS, we found spread of myeloblasts in combination with acute demyelinating lesions which corresponded to the antibody- and complement-mediated pattern II of multiple sclerosis lesions. This case implies that association of acute myeloid leukemia and acute CNS demyelination needs to be discussed and suggests that AML patients need to be strictly monitored for CNS functions.
