The narrow bony cochlear nerve canal in high resolution temporal bone computed tomography is frequently found in patients of congenital sensorineural hearing loss. But this bony structural anomaly could not conclude the functional outcome of cochlear nerve. Here, we present a case of a 14-month-old girl having bilateral narrow bony cochlear nerve canals. In magnetic resonance imaging, both the cochlear nerves were identified to be intact. Moreover, acoustic brainstem response threshold and auditory steady state response revealed nearly normal hearing thresholds. Therefore, we suggest that the narrow bony cochlear nerve canal itself does not necessarily indicate a substantial degree of hearing loss.

OBJECTIVETo summarize and critically evaluate the evidence for and against the effectiveness of Eastern-Western integrative medicine (EWIM) for health care compared to Eastern medicine (EM) or Western medicine (WM) alone.
METHODSSystematic searches were conducted on five Korean medical databases. Manual searches were also conducted through nine major Korean medical journals. Prospective randomized clinical trials (RCTs) were included if EWIM was tested for any type of conditions compared to EM or WM.
RESULTSThere were one hundred forty-one possibly relevant studies were identified, and seven RCTs were included. The risk of bias was high in most studies. The EWIM methods were compared with EM or WM in patients with pain conditions in four studies. These studies showed favorable effects of EWIM on pain reduction in patients with shoulder pain and chronic headache compared with EM, while the other RCTs failed to do so in traffic injury patients. Two studies tested EWIM in patients with Bell's palsy compared with EM and found acute functional improvement. An RCT comparing EWIM with WM in patients with acne showed a significant difference.
CONCLUSIONThe results of our systematic review suggest that there is limited evidence for the superiority of EWIM over EM or WM in the treatment of pain and acute symptom improvement in patients with Bell's palsy. The evidence from our analysis was limited from the low number of RCTs included and the high risk of bias. Future RCTs appear to be warranted.

PURPOSE: This study was to determine the incidence and severity of venous irriation in patients receiving vinorelbine tartrate (Navelbine ) in combination chemotherapy. MATERIAL AND METHODS: Twenty four patients histologically confirmed non-small cell lung cancer were enrolled in this study who receiving vinorelbine in combination chemotherapy through a peripheral vein from Oct. 1997 to Mar. 1999 with retrospective study design method. One group was 6~10 minutes infusion rate, the other was 10~20 minutes infusion rate with the same free-flow intravenous infusion. RESULTS: A total of 126 infusions were observed in this study. Sixty-two infusions were admi nistered at the 6~10 minutes, and 64 infusions were administered at the 10~20 minutes. The incidence of any venous irritation was 3.2% (2/62) in the group that received the infusion in 6~10 minutes and 10.9% (7/64) in 10~20 minutes (p=0.164), so we could not acquire any statistical significance. However the incidence of severe venous irritation (grade 3, 4) was 0% (0/62) in 6~10 minutes infusion group and 9.4% (6/64) in 10~20 minutes infusion group. There was a significant difference between two groups (p=0.028) CONCLUSION: Our results suggest that venous irritation associated with vinorelbine tartrate infusion can be reduced by shorter duration of administration and vinorelbine tartrate might be recom mended to administer at 6~10 minutes infusion in clinical practice.

Herba houttuyniae has been used as a constituent of herval medicine prescriptions for the treatment of inflammation, cancer, and other diseases. In the present study, we investigated the cellular effects of herba houttuyniae extract (HHE) and the signal pathways of HHE-induced apoptosis in HL-60 human promyelocytic leukemia cell line. HHE treatment caused apoptosis of cells as evidenced by discontinuous fragmentation of DNA, the loss of mitochondrial membrane potential, release of mitochondrial cytochrome c into the cytosol, activation of procaspase-9 and caspase-3, and proteolytic cleavage of poly(ADP-ribose) polymerase. Pretreatment of Ac-DEVD-CHO, caspase-3 specific inhibitor, or cyclosporin A, a mitochondrial permeability transition inhibitor, completely abolished HHE-induced DNA fragmentation. Together, these results suggest that HHE possibly causes mitochondrial damage leading to cytochrome c release into cytosol and activation of caspases resulting in PARP cleavage and execution of apoptotic cell death in HL-60 cells.

The transforaminal epidural injection (TFEI) has been preferred in many cases because it can deliver the injected dose of medication closer to the nerve root and better facilitate ventral epidural flow compared to other methods. However, in patients with deformities not demonstrated on fluoroscopic imaging, the needle may enter unwanted locations. We treated two cases of intradiscal injection of contrast dye, during the TFEI, in patients with lumbar disc herniation.

OBJECTIVETo evaluate the effectiveness of scalp acupuncture (SA), a modern acupuncture technique specialized to neurological disorders, in managing motor function and symptoms for Parkinson's disease (PD) patients.
METHODSTwo independent reviewers extracted data from all of the randomized clinical trials (RCTs) that assessed the efficacy of SA for PD compared with conventional therapies (CTs). Sixteen electronic databases were searched. The risk of bias was appraised with the Cochrane Collaboration tool, and the reporting of the included studies was evaluated by the Consolidated Standards of Reporting Trials (CONSORT) 2010 checklist and the revised Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) guidelines.
RESULTSIn total, 4 RCTs met the inclusion criteria. As assessed by the Unified PD Rating Scale (UPDRS), 2 RCTs showed that SA combined with CTs proved superior to CTs alone [60 cases; weighted mean difference, -3.94; 95% confidence interval (CI), -6.05 to -1.84, P=0.01; I(2) =0%]. Based on the Webster scale, however, 3 RCTs showed no superior effect of SA when combined with CTs with high heterogeneity (154 cases; risk ratio, 1.29; 95% CI, 0.79 to 2.12, P=0.30; I(2) =84%). The Cochrane risk of bias, adherence to the CONSORT and the STRICTA checklist showed that the quality of all the included RCTs was generally low.
CONCLUSIONSThe result of our systematic review and meta-analysis suggested that the effectiveness of SA for PD is promising, however, the evidence is not convincing. A sham-controlled RCT design that adheres to the CONSORT and STRICTA guidelines to overcome methodological weakness and that includes a large sample size is strongly recommended to confirm the precise effect of SA on PD.

Syndrome pattern (SP) is a core concept of Chinese medicine (CM) and is used to diagnose and treat patients based on an overall analysis of symptoms and signs. This study aimed to systematically review randomized controlled trials (RCTs) using the SP concept and to demonstrate how the SP concept could be applied to the study design of parallel RCTs, considering a gold standard of clinical research. After conducting a brief systematic review by way of a PubMed search, we analyzed how the SP concept was applied to the design of RCT in a CM herbal medicine trial. We then formulated possible research questions, applied the SP concept to answer the research questions, and suggested possible RCT designs to be used for conducting future trials. Fourteen RCTs were included in our systematic review, and three key points of the SP concept were formulated for the design of parallel RCTs: the time point of SP diagnosis between before and after randomization; the relationship between the international classification of diseases (ICD) and SP for the inclusion of target population; and the proper diagnostic method of SP. In this study, we formulated three possible research questions and then suggested perspectives for five possible RCT models arrived at using SP concepts. Future trials applying SP concept to RCTs should overcome the shortcomings of past SP trials, moving CM forward from experience-based to evidence-based medicine.

OBJECTIVERed ginseng (RG, Panax ginseng C.A. Meyer) is one of the widely used herbs for treating type 2 diabetes mellitus (DM). However, no systematic review of the effectiveness of RG for type 2 DM is available. This systematic review aimed to evaluate the current evidence for the effectiveness of RG in patients with type 2 DM.
METHODSElectronic searches of 14 electronic databases were conducted without language restrictions. All randomized clinical trials (RCTs) with RG as a treatment for type 2 DM were considered for inclusion. Their methodological quality was assessed using the Cochrane criteria.
RESULTSFour RCTs met our inclusion criteria. Their methodological quality was variable. Three of the RCTs compared the effectiveness of RG with placebo. The meta-analysis of these data failed to favor RG over placebo for fasting plasma glucose (FPG) [n =76, weighted mean difference (WMD): -0.43 mmol/L; 95% confidence interval (CI): -1.16 to 0.30, =0.25] and fasting plasma insulin (FPI) (n =76, WMD: -8.43 pmol/L; 95% CI: -19.54 to 2.68, P =0.14) for 12 weeks of treatment. One RCT compared the effects of RG with no treatment. The results did not suggest favorable effects of RG on FPG, hemoglobin A(1c) (HbA(1c)) or 2-h blood glucose after a meal (PP2h).
CONCLUSIONSThe evidence for the effectiveness of RG in controlling glucose in type 2 DM is not convincing. Few included studies with various treatment regimens prohibit definitive conclusions. More rigorous studies are needed to clarify the effects of RG on this condition.

OBJECTIVEMoxibustion is currently used for treating diabetes mellitus (DM) as a non-drug intervention in East Asian countries. This systematic review aims to evaluate the effectiveness of moxibustion for managing the symptoms of type 2 DM patients.
METHODSWe searched MEDLINE, AMED, EMBASE, CINAHL, The Cochrane Library, six Korean databases, and four Chinese databases. Risk of bias was used for evaluating the quality of the included studies.
RESULTSA total of 5 studies met the inclusion criteria for this review. All of the included studies had high risks of bias. One randomized clinical trial (RCT) compared the effectiveness of one-time moxibustion use with oral administration of glibenclimide and showed the significant effects of moxibustion on glycemic control. Another RCT tested the effectiveness of moxibustion plus conventional treatment, and the moxibustion group reported significant improvement in fasting and postprandial blood glucose levels compared with the conventional treatment group. Two RCTs compared the effectiveness of moxibustion versus acupuncture or moxibustion plus acupuncture, and the combined treatment showed the most favorable effects on the control of blood glucose, urine glucose, and glycocylated hemoglobin A(1c) (HbA(1c)). One uncontrolled observational study showed favorable effects of moxibustion on the response rate.
CONCLUSIONSIt is difficult to conclude that moxibustion is an effective intervention for the control of type 2 DM due to the scarcity of trials and the low methodological quality of included studies. Further rigorous RCTs may be necessary to evaluate the effectiveness of moxibustion for type 2 DM.
