Abstract PDF: Background
We aimed to evaluate the clinical efficacy of cervical epidural block (CEB) in enhancing upper extremity (UE) muscle strength in patients with cervical disc herniation (CDH).
Methods
Ten patients with CDH underwent a single CEB session. Follow-up assessments were conducted weekly for 2 weeks through outpatient visits. Handgrip strength on the affected side (AHGS) and the interlateral difference in handgrip strength (DHGS) between the affected and unaffected sides were measured using a dynamometer before, immediately after, 1 and 2 weeks after CEB. Neck pain and radiating UE pain were assessed using a visual analog scale (VAS) at baseline and 2 weeks posttreatment.
Results
The median patient age was 46.4 years (range, 35–78 years). The affected disc levels were C5–6 in five patients, C6–7 in three, and C5–6–7 in two. The left side was affected in six patients and the right in four. The mean VAS score for neck pain decreased from 7.2 to 2.9, whereas that for radiating UE pain decreased from 6.3 to 2.8 after treatment. Both the AHGS and DHGS improved significantly compared to the baseline values at all posttreatment times. However, no significant differences were observed among the posttreatment time points. These findings remained consistent even after adjusting for age and sex.
Conclusion
CEB may offer therapeutic benefits by alleviating pain and improving UE muscle weakness in patients with CDH. However, further large-scale prospective studies are required to validate these preliminary results and determine the long-term efficacy of CEB in managing CDH.

Sarcopenia is a condition in which muscle mass and strength are decreased and muscle function is impaired. It is an indicator of frailty and loss of independence in older adults. It is also associated with increased physical disability, which increases the risk of falls. As a multifactorial disease, sarcopenia is caused by a combination of factors including aging, hormonal changes, nutritional deficiencies, and physical inactivity. Understanding the underlying pathophysiology of sarcopenia and identifying its different causes is critical to developing effective prevention and treatment strategies. This review summarizes the pathophysiology, consequences, diagnostic methods, and multidisciplinary approaches to sarcopenia.

Abstract PDF: Shunt disconnection is an unreported complication of spinal mobilization and manipulation. We present the case of a young adult who underwent cystoperitoneal (CP) shunt placement for an arachnoid cyst at the age of 6 years. The shunt remained functional during a follow-up period of 11 years. The patient was admitted with headache and diplopia that started after cervical manipulation by a chiropractor. Radiography revealed fracture of the distal catheter and resultant enlargement of the temporosylvian cyst. The patient required replacement of the disconnected tubing caudal to the shunt valve. The distal catheter ruptured immediately below the outlet connector of the valve. The symptoms and signs resolved completely after insertion of a new distal tube into the peritoneum. This case report demonstrates that chiropractic manipulation of the neck may be a cause of tubing breakage in patients with CP shunts.

Abstract PDF: BACKGROUND
It is well known that non-rapid eye movement(NREM) sleep activates the occurrence of interictal epileptiform discharges(IED) in many epileptic syndromes. We performed this study to assess the effect of NREM sleep on IED in epileptic patients with organic brain lesions. MATERIALS AND METHODS: We analyzed awake and sleep electroencephalopathy(EEG) recorded simultaneously after partial sleep deprivation in 50 patients. We calculated the awake and sleep spike index (ASI and SSI, spikes/epoch), and the percentage increase of ASI and SSI during sleep. RESULTS: In the 50 patients, the IEDs were recorded exclusively during the awake state in 1 (2%) patient, and during the sleep state in 13(26%) patients. The SSI was higher in 44 (88%) patients, and the ASI was higher in 5 (10%) patients. The mean ASI and the SSI in patients with organic brain lesions were 0.058+/-0.121 and 0.148+/-0.187, and it was 0.081+/-0.150 and 0.174 +/-0.226 in patients without organic brain lesions. There were significant increases in the spike index (P<0.05) during NREM sleep in both groups (n=36), but no significant difference in the percent increase of spike index (P>0.05). CONCLUSION: The IEDs were activated significantly during NREM sleep both in patients with and without organic brain lesions, but there were no differences in the degree of activation in both groups. The activating effect of NREM sleep was not correlated with clinical factors such as, frequent nocturnal seizures, frequent generalized tonic clonic seizures, type of epilepsy and taking anticonvulsants. We conclude that the routine EEG used to evaluate epileptiform discharges in epileptic patients should include sleep recordings after partial sleep deprivation.

Abstract PDF: The Graf stabilization has been introduced in treating lumbar spinal disorder associated with posterior instability. This study reviewed some problems of the Graf instrumentation as a soft stabilizer. The purpose of this study is to analyse the problems of the soft stabilization in spinal instability. We reviewed 145 cases which were operative treatment using the Graf instrument for lumbar spinal disorder associated with posterior instability at our department from May, 1991 to Dec, 1995. The mean follow up periods was 29 months ranging from 24 months to 6 years 8 months. Of the 145 cases, 22 cases were showed the problem. The diagnostic method were simple x-ray, flexion-extension lateral stress view and CT scan. Results were as follows : Adjacent segmental instability was 10 cases(6.9%), disc space narrowing was 8 cases(5.5%), screw loosening was 3 cases(2.1%) and breakage of the Graf band was 1 case(0.6%). The problems of the soft stabilization were adjacent segmental instability, disc space narrowing, screw loosening, and breakage of the Graf band. But the rate of adjacent segmental instability and disc space narrowing was lower than other lumbar spinal instrumentation.

Abstract PDF: The disc internal disruption syndrome is not well known to us, but the following hypothesis is widely accepted in clinical practice. The disc internal disruption syndrome may develop intractable back pain with aggravated of pain, loss of spinal motion with any physical exercise, leg pain, loss of energy, marked weight loss, and profound depression. The patient with this syndrome will be found to have normal plain roentgenograms, myelograms, CT scans, results of blood examination and neurologic findings. For these reasons, this syndrome was frequently diagnosed by abnormal discographic findings. We had experience with two cases of disc internal disruption syndrome with clinical, roentgenographic and discographic evaluations. Thus we present these case with a brief review of the concerned literature.
