Neonatal diabetes mellitus (NDM) is defined as hyperglycemia that presents clinical symptoms within the first month of life and requires insulin therapy to maintain euglycemia. The diabetic condition may be transient, permanent, or transient with recurrence later in life. NDM is a rare clinical disorder. Three cases of NDM have been reported in Korea so far. We experienced two cases of NDM in twin brothers who were born with small for gestational ages. Their HLA typings were DR9 and DR14, and insulin autoantibody, islet cell antibody, GAD-reactive autoantibody, and insulin receptor antibody were not found. The genetic analysis with polymorphic DNA markers for chromosome 6 indicated paternal uniparental isodisomy.

Purpose:
This study examined whether there are seasonal variations in the number of plantar fasciitis cases from the database of the Korean Health Insurance Review & Assessment Service and an internet search of the volume data related to plantar fasciitis and whether there are correlations between variations.
Materials and Methods:
The number of plantar fasciitis cases per month was acquired from the Korean Health Insurance Review & Assessment Service from January 2016 to December 2019. The monthly internet relative search volumes for the keywords ‘‘plantar fasciitis” and ‘‘heel pain” were collected during the same period from DataLab, an internet search query trend service provided by the Korean portal website, Naver. Cosinor analysis was performed to confirm the seasonality of the monthly number of cases and relative search volumes, and Pearson and Spearman correlation analysis was conducted to assess the correlation between them.
Results:
The number of cases with plantar fasciitis and the relative search volume for the keywords “plantar fasciitis” and “heel pain” all showed significant seasonality (p<0.001), with the highest in the summer and the lowest in the winter. The number of cases with plantar fasciitis was correlated significantly with the relative search volumes of the keywords “plantar fasciitis” (r=0.632; p<0.001) and “heel pain” (r=0.791; p<0.001), respectively.
Conclusion
Both the number of cases with plantar fasciitis and the internet search data for related keywords showed seasonality, which was the highest in summer. The number of cases showed a significant correlation with the internet search data for the seasonality of plantar fasciitis. Internet big data could be a complementary resource for researching and monitoring plantar fasciitis.

OBJECTIVE: The authors prospectively analyzed the effect of one-level or two-level anterior cervical discectomy and fusion (ACDF), comparing stand-alone cages and cage-with-plate fixation constructs with respect to clinical outcomes and radiologic changes. METHODS: A total of 84 patients who underwent one-level (n=52) or two-level ACDF (n=32) for cervical disc disease and who completed 2 years of follow-up were included in this study. The patients were divided by cervical level and grouped into ACDF-Cage-only and ACDF-Cage-with-plate groups. The following parameters were assessed using radiographs: subsidence, C2–C7 lordosis angle, fusion segment angle, adjacent disc space narrowing, and fusion status. Clinical outcomes were assessed using the neck disability index (NDI) and visual analog scale scores for arm pain. RESULTS: In the comparison of one-level ACDF-cage-only and ACDF-cage-with-plate groups, the NDI score was better in the cage-only group at the 3-, 12-, and 24-month follow-ups: however, no significant difference in clinical outcomes was observed. In the comparison of two-level ACDF-cage-only and ACDF-cage-with-plate groups, no difference in any clinical outcome was observed between the two groups. At the 24-month follow-up, subsidence was observed in 45.8% of patients in the one-level cage-only group and 32.1% of patients in the one-level cage-with-plate fixation group. There was no statistically significant difference in the incidence rate between the two groups (p=0.312). Subsidence in the two-level cage-only group (66.6%) was significantly more frequent than in the two-level cage-with-plate fixation group (30%; p=0.049). The fusion rate for patients in the one-level cage-only group was not significantly different from that in the one-level cage-with-plate fixation group (cage-only, 87.5%; cage-with-plate fixation, 92.9%; p=0.425); fusion rate in the two-level patients were also similar between groups (cage-only, 83.3%; cage-with-plate fixation, 95%; p=0.31). CONCLUSION: Our clinical results showed that for single-level cases, plate fixation had no additional benefit versus cage-only; for two-level ACDF cases, the fusion rate and clinical outcomes were similar, although the cage-with-plate fixation group had a lower incidence of cage subsidence than did the cage-only group. We conclude that physicians should be aware of this possible disadvantage associated with using cervical plates in one-level ACDF. However, in two-level ACDF, subsidence is more likely to occur without plate fixation, and thus the addition of plate fixation should be considered.

A mediastinal mass and 2 lung masses on the lower lobes were detected by chest CT in a 44-year old woman. The mass on the left lower lobe was diagnosed as an adeno type of cancer by preoperative lung biopsy. But the preoperative lung biopsy exam for the mass on the right lower lobe couldn't perform because of patient's noncooperation. Removal of the mediastinal mass, left lower pulmonary lobectomy and wedge resection of the right lower pulmonary lobe were done. The histopathologic diagnosis of the resected mediastinal mass was mature cystic teratoma and both lung masses were the adeno type of cancer with the same histopathologic patterns. We experienced a rare case of lung adeno cancer together with mediastinal mature cystic teratoma.

STUDY DESIGN: In vitro cell culture model. PURPOSE: To investigate the effects of RNA interference (RNAi) on p75 expression and viability of rat notochordal cells treated with serum deprivation. OVERVIEW OF LITERATURE: RNAi enables the inhibition of specific genes by sequence-specific gene silencing using a double-stranded RNA. METHODS: Notochordal cells were isolated, cultured, and placed in 10% (control) or 0% (apoptosis-promoting) fetal bovine serum (FBS) for 48 hours. The expression of p75, apoptosis, and cell proliferation were determined. To suppress p75 expression, a small interfering RNA (siRNA) was synthesized against p75 (p75 siRNA) and transfected into cells. The suppression of p75 mRNA expression was investigated using the reverse transcription-polymerase chain reaction. The degree of p75 suppression was semiquantitatively analyzed using densitometry. The effect of p75 siRNA on apoptosis and proliferation of cells was determined. Solutions of an unrelated siRNA and transfection agent alone served as controls. RESULTS: Serum deprivation significantly increased apoptosis by 40.3%, decreased proliferation of notochordal cells by 45.3% (both, p<0.001), and upregulated p75 expression. The p75 siRNA suppressed p75 expression in cells cultured in 0% FBS. The rate of suppression by p75 siRNA of p75 mRNA was 72.9% (p<0.001). Suppression of p75 expression by p75 siRNA inhibited apoptosis by 7% and increased proliferation by 14% in cells cultured in 0% FBS (both, p<0.05). CONCLUSIONS: siRNA-mediated suppression of p75 inhibited apoptosis and increased proliferation of notochordal cells under conditions of serum deprivation, suggesting that RNAi might serve as a novel therapeutic approach for disc degeneration caused by insufficient viability of disc cells through the suppression of the expression of harmful genes.

Journal of Korean Society of Spine Surgery 2011;18(3):117-122
STUDY DESIGN: A retrospective study. OBJECTIVES: To assess the diagnostic value of the sedimentation sign seen on MRI with lumbar spinal stenosis and to compare postoperative clinical results. SUMMARY OF LITERATURE REVIEW: Nerve root sedimentation sign is an additional tool to diagnose lumbar spinal stenosis. MATERIALS AND METHODS: There were 302 patients enrolled that had been diagnosed with lumbar spinal stenosis by MRI, which were reviewed to identify a sedimentation sign and all underwent the operative treatment. There were 142 patients who could not have their spinal stenosis diagnosis confirmed by MRI, and thus were selected as the control group to estimate the diagnostic value of nerve root sedimentation sign. Correlation with the duration of preoperative symptoms and the number of involved segments were compared and analyzed between sedimentation sign positive (Group I) and negative (Group II). We estimated Million Visual Analogue Score (MVAS) and Korean Oswestry Disability Index (KODI) for the assessment of the pain and the functional disability. RESULTS: A positive sedimentation sign was found in 265 patients (87.7%) and diagnostic value was statistically significant (P<0.001). The involvement of 2 or more segments was significantly correlated with the sedimentation sign in the positive group (P<0.001). MVAS presented the improvement of 64.5+/-4.6%, KODI, 62.9+/-3.9% after surgical treatment in Group I. In Group II, each score showed improvement of 34.6+/-2.3% (MVAS), 37.1+/-1.8% (KODI). The improvement of these scores in Group I was better than in Group II. CONCLUSIONS: The nerve root sedimentation sign is an additional tool to diagnose lumbar spinal stenosis and the considerable factor to decide the operation.

PURPOSE: The most concerning issue in children with urinary tract infection(UTI) is the probability of underlying genitourinary anomalies and vesicoureteral reflux(VUR), which is frequently associated with renal scarring and eventually end-stage renal disease. Therefore, voiding cystourethrography(VCUG) is usually recommended at the earliest convenient time for children with UTI. However, VCUG is an invasive procedure that requires catheterization and exposure to X-ray. In this study, we aimed to determine the predictability of clinical, laboratory and imaging parameters for VUR in children with UTI. METHODS: Data of children with bacteriologically proven UTI who underwent VCUG were evaluated retrospectively for clinical(age, gender, fever), laboratory(leukocytosis, ESR, CRP, pyuria, blood urea nitrogen, serum creatinine) and imaging(renal ultrasound and DMSA renal scan) findings. First, children with UTI were divided into two groups according to the presence of VUR as non-VUR group and with VUR group, and clinical, laboratory variables were compared between these groups. Second, patients who had VUR were reclassified as low- grade VUR(grade I-II) group and high-grade(grade III-V) VUR group according to grading of VUR, and clinical, laboratory and imaging variables were compared between these groups. RESULTS: Among 410 children with UTI, 137 had VUR and 78 high-grade VUR. Fever, leukocytosis, ESR, CRP, pyuria were associated with VUR. In addition, abnormal findings of ultrasonography and DMSA renal scan were closely related to VUR. However, these clinical and laboratory variable in patients with high grade VUR were not different significantly, compared to those with low-grade VUR group. CONCLUSIONS: Fever, leukocytosis, ESR, CRP seems to be potentially useful predictors of VUR in pediatric patients with UTI. In addition, renal ultrasonography and DMSA renal scan findings supported the presence of VUR. Further study of these findings could limit unnecessary VCUG in patients with UTI.
