A 38-year-old female with systemic lupus erythematosus (SLE) initiated belimumab treatment. One month later, she presented with a reddish painful swelling on her right lower leg.She was treated with ceftriaxone and vancomycin. However, novel erythematous papules and indurated nodules appeared on both her lower legs. Skin biopsy revealed microabscess formation with mixed cell granuloma surrounded by inflammatory cell infiltration within the dermis with subcutaneous fat tissue. A large number of acid-fast bacilli were observed with Ziehl–Neelsen staining. DNA sequencing of both the hsp65 and the 16S rRNA sequences showed a 100% match with the corresponding region of Mycobacterium haemophilum. Mycobacterial culture revealed satellite growth enhancement on Middlebrook 7H11 agar plates around a paper strip containing hemin. She was treated with levofloxacin, rifabutin, and ethambutol. Within 13 months, her cutaneous lesions improved markedly without any side effects. The B cell-targeted biologic belimumab, a fully humanized IgG1γ monoclonal antibody that inactivates B lymphocyte stimulator, has been considered to be beneficial for active SLE. However, this therapy could increase the risk for the development of biologic therapy-associated mycobacterial infections, both tuberculosis and nontuberculous mycobacteria infections.

Background:
Alopecia areata (AA) is considered complex genetic and tissue-specific autoimmune disease. We recently discovered a nonsynonymous variant in the coiled-coil alphahelical rod protein 1 (CCHCR1) gene within the AA risk haplotype. And a water avoidance stress test on CCHCR1 knockout mice induced AA-like lesions.
Objective:
To investigate the difference clinical findings of AA in patients with the CCHCR1 variant and without.
Methods:
We conducted a retrospective analysis of the data from 142 AA patients. Among these patients, 20 (14.1%) had a variant of CCHCR1. We evaluated the sex distribution of the patients, age at onset, distribution of the clinical types, prevalence of a positive family history of AA, prevalence of association of AA with atopic dermatitis, response to steroid therapy, and recurrence rate. We used multivariate logistic regression analysis and Fisher’s exact test for statistical analysis. We also investigate electron microscopic observations of hair samples with the CCHCR1 variant and without.
Results:
The results showed a significant correlation between the CCHCR1 variant and the recurrence rate compared with the variant-negative group (p=0.0072). Electron microscopy revealed abnormalities in the hair shaft structure and hair cuticle in patients with the CCHCR1 variant (p=0.00174).
Conclusion
Our results suggest that AA with CCHCR1 variant is clinically characterized by a high recurrence rate and hair morphological abnormality.

Purpose:
The aim of this study was to evaluate the short-term outcome of physiotherapy in patients with acetabular labral tears and to assess the effectiveness of physiotherapy according to the severity of the labral tear.
Materials and Methods:
Thirty-five patients who underwent physiotherapy for treatment of symptomatic acetabular labral tears were enrolled. We evaluated the severity of the acetabular labral tears, which were classified based on the Czerny classification system using 3-T MRI. Clinical findings of microinstability and extraarticular pathologies of the hip joint were also examined. The International Hip Outcome Tool 12 (iHOT12) was use for evaluation of outcome scores pre- and post-intervention.
Results:
The mean iHOT12 score showed significant improvement from 44.0 to 73.6 in 4.7 months. Compared with pre-intervention scores, significantly higher post-intervention iHOT12 scores were observed for Czerny stages I and II tears (all P<0.01). However, no significant difference was observed between pre-intervention and post-intervention iHOT12 scores for stage III tears (P=0.061). In addition, seven patients (20.0%) had positive microinstability findings and 22 patients (62.9%) had findings of extra-articular pathologies. Of the 35 patients, eight patients (22.9%) underwent surgical treatment after failure of conservative management; four of these patients had Czerny stage III tears.
Conclusion
The iHOT12 score of patients with acetabular labral tears was significantly improved by physiotherapy in the short-term period. Improvement of the clinical score by physiotherapy may be poor in patients with severe acetabular labral tears. Determining the severity of acetabular labral tears can be useful in determining treatment strategies.

Objective:
The survival benefits of retroperitoneal lymphadenectomy (RLNA) for epithelial ovarian cancer (EOC) remain controversial because clinical behaviors differ among subtypes. The purpose of the present study was to clarify whether RLNA increases the survival rate of advanced high-grade serous carcinoma (HGSC).
Methods:
This was a retrospective cohort analysis of 3,227 patients with EOC treated between 1986 and 2017 at 14 institutions. Among them, 335 patients with stage IIB-IV HGSC who underwent optimal cytoreduction (residual tumor of <1 cm) were included. Patients were divided into the RLNA group (n=170) and non-RLNA group (n=165). All pathological slides were assessed based on a central pathological review. Oncologic outcomes were compared between the two groups in the original and weighted cohorts adjusted with the inverse probability of treatment weighting.
Results:
The median observation period was 49.8 (0.5–241.5) months. Overall, 219 (65%) out of 335 patients had recurrence or progression, while 146 (44%) died of the disease. In the original cohort, RLNA was a significant prognostic factor for longer progression-free survival (PFS) (hazard ratio [HR]=0.741; 95% confidence interval [CI]=0.558–0.985) and overall survival (OS) (HR=0.652; 95% CI=0.459–0.927). In the weighted cohort in which all variables were well balanced as standardized differences decreased, RLNA was also a significant prognostic factor for more favorable oncologic outcomes (PFS, adjusted HR=0.742; 95% CI=0.613–0.899) and OS, adjusted HR=0.620; 95% CI=0.488–0.787).
Conclusion
The present study demonstrated that RLNA for stage III-IV HGSC with no residual tumor after primary debulking surgery contributed to better oncologic outcomes.

It has been reported that 30% of deaths related to the Kumamoto Earthquakes were among those who had spent nights in the car. Spending nights in the car imposes heavy mental and physical burden, but it has been examined in only a few studies. At 1 year after the Kumamoto Earthquakes, this study examined the factors affecting the mental health of 460 disaster-affected workers at 13 companies who stayed in the car. It was found that 181 workers (72.7%) had spent nights in the car. They had significantly higher scores on the Athene Insomnia Scale, revised Impact of Event Scale (IES-R), and General Health Questionnaire (GHQ) 28 compared with workers who had not stayed overnight in the car. Multiple regression analysis showed that “physical functioning”, “social functioning”, “anxiety and insomnia”, and “staying in the car” were factors affecting the IES-R score, while “vitality”, “avoidance symptoms”, “staying in the car”, and “subjective symptoms” were factors affecting the GHQ 28 score. Mental burden on workers in a natural disaster are imposed in addition to accumulated work burden. Given that mental burden may not ease over a prolonged period, there appears to be a substantial need to urgently discuss how assistance measures should be provided.

OBJECTIVE:
This study estimated the effects of weekend and off-hour childbirth and the size of perinatal medical care center on the incidence of cerebral palsy.
METHODS:
The cases were all children with severe cerebral palsy born in Japan from 2009 to 2012 whose data were stored at the Japan Obstetric Compensation System for Cerebral Palsy database, a nationally representative database. The inclusion criteria were the following: neonates born between January 2009 and December 2012 who had a birth weight of at least 2000 g and gestational age of at least 33 weeks and who had severe disability resulting from cerebral palsy independent of congenital causes or factors during the neonatal period or thereafter. Study participants were restricted to singletons and controls without report of death, scheduled cesarean section, or ambulance transportation. The controls were newborns, randomly selected by year and type of delivery (normal spontaneous delivery without cesarean section and emergency cesarean section) using a 1:10 case to control ratio sampled from the nationwide Japan Society of Obstetrics and Gynecology database.
RESULTS:
A total of 90 cerebral palsy cases and 900 controls having normal spontaneous delivery without cesarean section were selected, as were 92 cerebral palsy cases and 920 controls with emergent cesarean section. A significantly higher risk for cerebral palsy was found among cases that underwent emergent cesarean section on weekends (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.06-2.81) and during the night shift (OR 2.29, 95% CI 1.30-4.02). No significant risk was found among normal spontaneous deliveries on weekends (OR 1.63, 95% CI 0.97-2.73) or during the quasi-night shift (OR 1.26, 95% CI 0.70-2.27). Regional perinatal care centers showed significantly higher risk for cerebral palsy in both emergent cesarean section (OR 2.35, 95% CI 1.47-3.77) and normal spontaneous delivery (OR 2.92, 95% CI 1.76-4.84).
CONCLUSION
Labor on weekends, during the night shift, and at regional perinatal medical care centers was associated with significantly elevated risk for cerebral palsy in emergency cesarean section.

Nutritional status tends to be poor in patients undergoing chemotherapy. We investigated anorexia caused by olfactory dysfunction by examining olfactory sense in chemotherapy patients and healthy volunteers. We used the Open Essence® olfactometry test, which assesses the accuracy of identifying 12 different odors. Twenty-seven patients (mean age 69.8 years) who received chemotherapy for lung cancer from March 2016 to September 2017 participated in multiple olfactometry examinations from the start of their chemotherapy. We also examined 284 healthy volunteers (mean age 41.9 years), and performed an additional subgroup analysis with 35 volunteers aged 60 years or older (mean age 73.2 years) to more closely align with the mean age of the patients. The mean accuracy rate was 44.4% for the patients, although this rate varied from odor to odor. In contrast, the mean accuracy rate of the healthy volunteers was 76.8%. There were significant differences according to sex and smoking history. For the subgroup of healthy volunteers aged 60 years and older, the mean accuracy rate was 54.5%; accuracy rate decreased as age increased. There was no significant difference in the accuracy rate according to type of chemotherapy, but the overall rate for patients was lower than that for healthy volunteers. Our results show that olfactory sense in lung cancer patients undergoing chemotherapy is altered compared with that in healthy individuals. Smoking habit was shown to have the greatest effect and most of the lung cancer patients in this study were smokers. A change in olfactory sense caused by smoking was also noted in the healthy volunteer group. We intend to conduct a similar investigation of patients with diseases other than lung cancer in the future as well as utilize the findings to investigate nutritional status.

Osteoporosis and Sarcopenia 2019;5(4):116-121
OBJECTIVES:
To assess the vitamin D status in postmenopausal women with osteoporotic fractures, determine its concentration by fracture site at the clinical setting, and compare the proportion of vitamin D deficiency with that reported in literature.
METHODS:
The prospective study included 317 postmenopausal women with osteoporotic fractures who were treated consecutively from 2016 to 2018. After obtaining informed consent for participation in the seamless treatment of osteoporosis against fractures study, which is our initiative to prevent secondary osteoporotic fractures, we registered the patients, examined bone mineral density (BMD) at the unfractured femoral neck and lumbar spine, serum 25-hydroxyvitamin D (25(OH)D) concentration, blood chemistry, and bone turnover markers.
RESULTS:
The mean age of the patients was 80.7 years. Moreover, 78% of patients of all fractures had 25(OH)D concentration < 20 ng/mL, whereas 12% of patients had 25(OH)D concentration ≥ 30 ng/mL 25(OH)D concentration in hip fractures was significantly lower than that in vertebral or distal radius fractures (P < 0.05). Multiple regression analysis revealed that 25(OH)D concentration is significantly associated with femoral neck BMD (β = 0.16; 95% confidence interval [CI], 0.78–12.17, P = 0.03) and serum albumin concentration (β = 0.21; 95% CI, 0.62–2.96, P < 0.001) in patients with 25(OH)D concentration < 30 ng/mL.
CONCLUSIONS
The results of this study show that the proportion of postmenopausal women with osteoporotic fractures who had vitamin D deficiency was higher than the proportion in previous reports that examined general postmenopausal women (35.2%–52.0%).
