ABSTRACT
Objectives: Lumbar spondylolysis is a common condition; nonetheless, its cause in patients with spastic cerebral palsy (CP) remains unknown. Furthermore, examination of children with CP may not accurately capture complaints, thus causing diseases to be overlooked. Understanding the clinical features and gait patterns of lumbar spondylolysis in CP can aid in diagnosis. This study aimed to identify the clinical features and specific gait patterns of lumbar spondylolysis in ambulatory children with CP. Methods: Seventy-three children with CP were divided into two groups according to the presence or absence of lumbar spondylolysis on X-ray and magnetic resonance imaging. Three-dimensional gait analysis (3DGA) was performed to evaluate the kinematic data of the lower limbs. Results: Eight participants (11.4%) had lumbar spondylolysis primarily affecting the L5 vertebra. The lumbar spondylolysis group had a higher body weight and Body Mass Index, along with a smaller left popliteal angle on the spastic side. In 3DGA, detailed kinematic data indicated significant group differences in the mean angles of hip internal rotation (39.6° vs. 20.2°) during an entire gait cycle. The gait profile score was 19.7° in the lumbar spondylolysis group and 14.9° in the spinal uninvolved group; the difference in gait profile score between the two groups showed a minimal clinically important difference of 2.75. Conclusions: The overall gait profile score revealed that the gait of the lumbar spondylolysis group was deteriorated. Excessive internal rotation of the hip during gait might be a contributing factor to lumbar spondylolysis in children with CP.
ABSTRACT
PURPOSE: The objective of this study was to examine the association between pain catastrophizing in acute phase herpes zoster and the development of postherpetic neuralgia. METHODS: The medical records of all patients diagnosed with herpes zoster between February 2016 and December 2021 were retrieved. Inclusion criteria were patients aged > 50 years who visited our pain center within 60 days after rash onset and reported a pain intensity of ≥ 3 in a numerical rating scale. Patients with a score of 30 or more in the pain catastrophizing scale at baseline were assigned to the catastrophizer group, and those with a score < 30 were assigned to the non-catastrophizer group. We defined patients with "postherpetic neuralgia" and "severe postherpetic neuralgia" as those with a numerical rating scale score of 3 or more and 7 or more at 3 months after baseline, respectively. RESULTS: Data of 189 patients were available for complete analysis. Age, baseline numerical rating scale, and prevalence of anxiety and depression were significantly higher in the catastrophizer than those in the non-catastrophizer group. Incidence of postherpetic neuralgia did not differ significantly between the groups (p = 0.26). Multiple logistic regression analysis showed that age, severe pain at baseline, and immunosuppressive state were the factors which were independently associated with developing postherpetic neuralgia. Severe pain at baseline was the only factor related to developing severe postherpetic neuralgia. CONCLUSION: Pain catastrophizing in the acute phase of herpes zoster may not be related to the development of postherpetic neuralgia.

BACKGROUND: Morphologically, osteofibrous dysplasia-like adamantinoma is thought to be intermediate between osteofibrous dysplasia and adamantinoma. Its treatment is not well established owing to its rarity. CASE PRESENTATION: We report about of a 10-year-old girl with osteofibrous dysplasia-like adamantinoma initially diagnosed as osteofibrous dysplasia and treated via intercalary segmental resection with partial cortex preservation using a pedicled vascularized fibula graft for reconstruction. Bone union was observed 9 weeks after surgery. Twenty-two months after the definitive surgery, no recurrence was observed. CONCLUSION: This case illustrates the upgrade from osteofibrous dysplasia to osteofibrous dysplasia-like adamantinoma. The surgical method may aid the treatment of osteofibrous dysplasia-like adamantinoma with incomplete cortex involvement of the tumor.

Conifer and broadleaf trees emit volatile organic compounds in the summer. The major components of these emissions are volatile monoterpenes. Using solid phase microextraction fiber as the adsorbant, monoterpenes were successfully detected and identified in forest air samples. Gas chromatography/mass chromatogram of monoterpenes in the atmosphere of a conifer forest and that of serum from subjects who were walking in a forest were found to be similar each other. The amounts of α-pinene in the subjects became several folds higher after forest walking. The results indicate that monoterpenes in the atmosphere of conifer forests are transferred to and accumulate in subjects by inhalation while they are exposed to this type of environment.
ABSTRACT
Abstract Autonomic neuropathy, although often reported to occur in patients with AL (amyloid of light chain of immunoglobulin) amyloidosis, is extremely rare in AA (amyloid A) amyloidosis. We describe a patient with AA amyloidosis secondary to rheumatoid arthritis (RA) in whom autonomic neuropathy resulted in gustatory sweating during the end stage of RA. We discuss the importance of gustatory sweating as a characteristic sign of autonomic nervous system dysfunction in AA amyloidosis secondary to RA, and stress the availability of cardiovascular autonomic tests as an indicator of autonomic neuropathy in not only AL amyloidosis but also AA amyloidosis.
ABSTRACT
Secondary amyloid A (AA) amyloidosis is an uncommon yet important complication of rheumatoid arthritis (RA). It is one of the most relentless of the extra-articular features of RA, and suitable treatments have not yet been found. We studied the efficacy of cyclophosphamide (CYC) combined with prednisolone (PSL) in amyloidotic patients who had serum amyloid A (SAA) 1.3 genotype, which is a risk factor for secondary amyloidosis in Japanese RA patients. Fifteen RA patients who were SAA1.3 homo- and heterozygotes with biopsy-confirmed AA amyloidosis were treated with a combination of CYC and PSL. Laboratory variables of C-reactive protein (CRP), rheumatoid factor (RF), erythrocyte sedimentation rate (ESR), serum albumin (Alb), serum creatinine (Cre) and Lansbury's index were carried out by statistical analysis of changes between before and during the medication. According to the Mann-Whitney rank test, CRP, RF, ESR, Alb and Cre levels improved significantly with the combination treatment (p<0.05). Also, paired t-tests showed significance in Lansbury's index between before and during the medication (p=0.007). CYC combined with PSL ameliorated not only laboratory markers but also clinical rheumatoid activity in patients with amyloidosis secondary to RA, whose genotypes were SAA1.3 homo- and heterozygous. CRP, ESR, RF, Alb and Cre will be surrogate markers of therapeutic efficacy. The combination of CYC and PSL appears to be beneficial for Japanese RA patients who are SAA1.3 homo- and heterozygous carriers, associated with secondary AA amyloidosis.

We describe an unusual case of a 38-year-old woman with a localised form of polyarteritis nodosa (PAN) manifested by acute onset of severe calf pain. Magnetic resonance imaging of the lower legs showed abnormal signal intensity of the outer calves muscle. Biopsies of the gastrocnemius revealed an acute necrotising arteritis with marked non-specific fasciitis. The diseased muscle improved with corticosteroid administration alone. The fascial involvement likely contributed to the severity of the clinical features of PAN, which may be related to a previous hepatitis B virus infection.
