STUDY DESIGN: Case Report. OBJECTIVES: The aim of this study was to report 2 cases of calcified spinal meningioma that displayed differences in appearance during resection, and to review the current literature on calcified and ossified spinal meningiomas. SUMMARY OF LITERATURE REVIEW: Calcified and ossified spinal meningiomas are rare, and tumor calcification is a risk factor for poor neurological outcomes resulting from the additional manipulations required to dissect the tumor. MATERIALS AND METHODS: We describe the clinical course and intraoperative findings of 2 female patients who presented with symptoms of myelopathy. Magnetic resonance imaging showed calcified spinal meningiomas of the thoracic spine. The type of tumor resection performed was dependent on the solidity and texture of the individual tumors. RESULTS: Pathologic evaluation revealed psammoma bodies, which suggested calcified meningioma. The patients' neurologic symptoms resolved with no neurologic sequelae. CONCLUSIONS: Although there are a few pathologic differences regarding the main type and pathogenesis of ossified and calcified meningioma, both are thought to have a poor prognosis. For these tumors, adequately accounting for the expected poor prognosis and performing a wide laminectomy in order to ensure an adequate surgical margin are important factors for achieving a favorable outcome.

OBJECTIVES: To identify work-related musculoskeletal symptoms and any associated work-related risk factors, focusing on structural labor factors among hotel workers. METHODS: A total of 1,016 hotel workers (620 men and 396 women) were analyzed. The questionnaire surveyed participants' socio-demographics, health-related behaviors, job-related factors, and work-related musculoskeletal symptoms. Work-related musculoskeletal symptoms were assessed using the Nordic musculoskeletal questionnaire. All analyses were stratified by gender, and multiple logistic regression modeling was used to determine associations between work-related musculoskeletal symptoms and work-related risk factors. RESULTS: The risk of developing work-related musculoskeletal symptoms was 1.9 times higher among male workers in the kitchen department than males in the room department (OR = 1.92, 95% CI = 1.03-3.79), and 2.5 times higher among male workers with lower sleep satisfaction than those with higher sleep satisfaction (OR = 2.52, 95% CI = 1.57-4.04). All of the aforementioned cases demonstrated a statistically significant association with work-related musculoskeletal symptoms. Moreover, the risk of developing work-related musculoskeletal symptoms was 3.3 times higher among female workers aged between 30 and 34 than those aged 24 or younger (OR = 3.32, 95% CI = 1.56-7.04); 0.3 times higher among females in the back office department than those in the room department (OR = 0.34, 95% CI = 0.12-0.91); 1.6 times higher among females on shift schedules than those who were not (OR = 1.60, 95% CI = 1.02-2.59); 1.8 times higher among females who performed more intensive work than those who performed less intensive work (OR = 1.88, 95% CI = 1.17-3.02), and; 2.1 times higher among females with lower sleep satisfaction than those with higher sleep satisfaction (OR = 2.17, 95% CI = 1.34-3.50). All of the aforementioned cases also displayed a statistically significant association with work-related musculoskeletal symptoms. CONCLUSION: This study focused on structural risk factors in the working environment, such as the gender-based division of labor, shift work and labor intensity, that demonstrated a statistically significant correlation with the work-related musculoskeletal symptoms of hotel workers. Both men and women reported different prevalence rates of work-related musculoskeletal symptoms among different departments. This could indicate that a gender-based division of labor produces different ergonomic risk factors for each gender group. However, only females displayed a statistically significant correlation between shift work and labor intensity and musculoskeletal symptoms. Thus, minimizing ergonomic risk factors alone does not suffice to effectively prevent musculoskeletal diseases among hotel workers. Instead, work assignments should be based on gender, department, working hours and work intensity should be adjusted to address multi-dimensional musculoskeletal risk factors. In addition, an approach that seeks to minimize shift work is needed to reduce the incidence of musculoskeletal disorders.

The pathogenesis of juxtafacet cysts is closely related to degenerative instability of the lumbar spine and degenerative changes in the ligamentum flavum and the facet joint. A 56-year-old man presented with severe right thigh pain and numbness for 1 month after a laminar fracture of the L4 spine. Magnetic resonance imaging revealed a heterogenous cystic mass surrounding the facet joint between the fourth and fifth lumbar vertebrae on the right side. Conservative therapy was unsuccessful and the lesion was removed by surgical decompression alone without fusion. The histological examination showed a fragmented, cystic wall-like structure composed of myxoid degenerative tissue without lining epithelium. Here we present this case of a ganglion cyst that appeared to be associated with facet joint instability.

Background:
and Purpose Spinocerebellar ataxias (SCAs) are the most common form of hereditary ataxias. Extracerebellar signs have been well described and are helpful in differentiating the SCA subtypes. However, there are few reports on the early-stage extracerebellar signs in various SCA subtypes. This study explored the clinical and magnetic resonance imaging (MRI) characteristics of early-stage SCAs in the Korean population.
Methods:
We retrospectively reviewed the medical records of genetically confirmed SCA patients with a disease duration of <5 years. Data on baseline characteristics, extracerebellar signs, and initial MRI findings were organized based on SCA subtypes.
Results:
This study included 117 SCA patients with a median age at onset of 40.6 years. The family history was positive in 71.8% of the patients, and the median disease duration and the score on the Scale for the Assessment and Rating of Ataxia at the initial visit were 2.6 years and 5.0, respectively. SCA3 was the most prevalent subtype, and oculomotor abnormalities were the most frequent extracerebellar signs in early-stage SCAs. Saccadic slowing was characteristic of SCA2 and SCA7, and gaze-evoked nystagmus was prominent in SCA6. Parkinsonism was relatively frequent in SCA8 and SCA3. Decreased visual acuity was specific for SCA7. Dementia was not an early manifestation of SCAs. Brain MRI revealed a pattern of pontocerebellar atrophy in SCA2 and SCA7, while SCA6 demonstrated only cerebellar cortical atrophy.
Conclusions
SCA patients exhibited diverse extracerebellar signs even in the early stage.Specific extracerebellar signs were characteristic of specific subtypes, which could facilitate differential diagnoses of early-stage SCAs.

OBJECTIVE: To evaluate the effectiveness of CC+FSH or CC+hMG in intrauterine insemination (IUI) cycles for the treatment of infertility. METHOD: Patients received daily 100 mg of clomiphene citrate (CC) for 5 days followed by hMG or FSH. A single IUI was performed at 36 h after hCG. Clinical pregnancy was classified if a gestational sac or fetal cardiac activity was seen on ultrasound. RESULTS: The overall clinical pregnancy rate was 19.1% per cycle (17/89) and 21.5% per patient (17/79). More clinical pregnancies were recorded in CC+FSH (23.1%, 6/26) than CC+hMG cycles (17.5%, 11/63), but this difference was not statistically significant. No differences were found in age, duration of infertility, follicle size, levels of estradiol (E2) on the day of hCG injection and total motile sperm counts between pregnant and non-pregnant groups. However, more ampules of gonadotropins were used in pregnant group than non-pregnant group (p<0.05). CONCLUSION: Combination of CC and hMG may economically be more effective to induce ovulation for IUI compared to CC and FSH.

OBJECTIVE: This study was designed to evaluate the effects of endogenous LH surge, GnRH agonist (GnRH-a) or human chorionic gonadotropin (hCG) as ovulation trigger on pregnancy rate by intrauterine insemination (IUI). METHOD: Patients received daily 100 mg of clomiphene citrate (CC) for 5 days stating on the third day of the menstrual cycle followed by human menopausal gonadotropin (hMG) for ovulation induction. Follicles larger than >16 mm in diameter were present in the ovary, frequent LH tests in urine were introduced to detect an endogenous LH surge. Final follicular maturation and ovulation were induced by GnRH-a 0.1 mg (s.c.) or hCG 5,000~10,000 IU (i.m.) administration except natural ovulation. Pregnancy was classified as clinical if a gestational sac or fetal cardiac activity was seen on ultrasound. RESULTS: There were no differences in age, duration of infertility and follicle size, but more ampules of hMG were used in GnRH-a group compared to hCG 10,000 IU treated group (p<0.05). Lower level of estradiol (E2) on the day of hCG or GnRH-a injection was observed in hCG 10,000 IU group than other treatment groups (p<0.01). The overall clinical pregnancy rate was 19.8% per cycle (32/162) and 22.2% per patient (32/144). Pregnancy rate was higher in natural-endogenous LH surge group (37.5%, 9/24) than GnRH-a (18.8%) or hCG treated group (20.9% & 13.9%), but this difference was not statistically significant. No patient developed ovarian hyperstimulation. Abortion rate was 22.2% (2/9) in hCG 5,000 IU group. Delivery or ongoing pregnancy rate was 37.5% (9/24), 18.8% (3/16), 16.3% (7/43) and 13.9% (11/79) in endogenous LH surge, GnRH-a, hCG 5,000 IU and hCG 10,000 IU treatment groups, respectively. CONCLUSION: These results support the concept that use of natural-endogenous LH surge in stimulated cycles may be more effective to obtain pregnancies by IUI than GnRH-a or hCG administration.

OBJECTIVE: To assess the effectiveness of modified dynamic metacarpophalangeal joint flexion orthoses for treatment of post-burn hand contractures. METHOD: We enrolled 42 hand burn patients with limited range of motion at the metacarpophalangeal joints in this study. The patients were randomly assigned into either a control or an orthotic group. Both groups received the standard rehabilitation therapy focused on hand therapy; 21 subjects in the orthotic group wore a splint for 3 hours per day for 8 weeks. Hand function was measured by active range of motion, grip strength and other assessment tools. All parameters were estimated using the Mann-Whitney U test at the beginning and the end of the treatment after 8 weeks. RESULTS: The 21 subjects that had an orthotic intervention showed significant improvement in the range of motion at 2nd, 3rd, 4th and 5th metacarpophalangeal joints (p<0.05). However, the grip strength was not significantly increased after the 8 weeks of treatment compared to control group (p>0.05). There was a significant difference in the hand function scales between the 2 groups (p<0.05). CONCLUSION: The modified dynamic metacarpophalangeal joint flexion orthoses provide continuous flexion to metacarpophalangeal joint that is needed for the restoration of range of motion in post-burn hand contractures. For the clinical application of hand orthoses in patients with hand disorders, additional research into its affects are required.

We present two cases of the patients with spinal muscular atrophy(SMA) confirmed by molecular genetic studies. The first one is 1-year-old female child with SMA type II(Dubowitz disease) who visited pediatric outpatient for developmental delay. She presented lower extremity hypotonia which progress to upper extremities and inability to sit alone. Spinal cord MRI showed normal findings but the needle electromyography suggested the possibility of myopathy. Following muscle biopsy findings were consistent with spinal muscular atrophy and PCR-SSCP(polymerase chain reaction-single strand conformation polymorphism) analysis showed homozygous deletion of telomeric SMN(survivor motor neuron) exon 7. The second is a 19-year-old female with SMA type III(Kugelberg-Welander disease) who visited neurologic outpatient for limbs weakness. She presented slowly progressive gait disturbance without muscle atrophy. The significantly decreased motor power of proximal limbs was observed. And findings of electromyography and muscle biopsy were consistent with spinal muscular atrophy. PCR-SSCP analysis revealed homozyous deletion of exon 7 of telomeric SMN and deletion of exon 8 of centromeric SMN gene. PCR analysis for NAIP(neuronal apoptosis inhibitory protein) exon 5 and 13 revealed no deletion in both cases. Molecular genetic analysis for SMN gene will be very useful for rapid diagnosis of spinal muscular atrophy.

OBJECTIVE: To investigate the effect of extracorporeal shock wave therapy (ESWT) on painful stump neuroma. METHODS: Thirty patients with stump neuroma at the distal end of an amputation site were assigned randomly to the ESWT group (n=15) and the transcutaneous electrical nerve stimulation (TENS)+desensitization+pharmacological treatment group (n=15). For 3 weeks, the ESWT group received a weekly session involving 1,500 pulses at 0.10 mJ/mm2, while the control group was treated 10 times each, 40 minutes per day with TENS and desensitization treatment, and daily medication for 3 weeks. ESWT stimulation was given by focusing on the area at the neuroma site clearly identified by ultrasound. RESULTS: The changes in the McGill pain questionnaire were 38.8+/-9.0 prior to treatment and 11.8+/-3.1 following the treatment. The corresponding values for the control group were 37.2+/-7.7 and 28.5+/-10.3. The changes between groups were significantly different (p=0.035). The change in visual analog scale prior to and after treatment was 7.0+/-1.5 and 2.8+/-0.8 in the ESWT group, respectively, and 7.2+/-1.4 and 5.8+/-2.0 in the control group. These changes between the groups were also significantly different (p=0.010). The outcome in the pain rating scale also showed significant differences between groups (p<0.001). Changes in neuroma size and pain pressure threshold (lb/cm2) were not significantly different between groups (p>0.05). CONCLUSION: The study findings imply that ESWT for stump neuroma is superior to conventional therapy.
