Background: Nine years have passed since the Journal of Bone Metabolism (JBM) was launched as an English journal in 2012; it was finally included in Scopus in January 2019. Therefore, this study aimed to provide evidence of increased international recognition based on journal metrics and reflect on its efforts to be recognized as a top-notch journal. Methods: Databases, such as the Web of Science (WoS), Scopus, Korean Citation Index (KCI), and citation indicators, including the impact factor (IF) and SCImago journal rank (SJR) were reviewed and calculated according to years, and the results were drawn. Furthermore, country-wise contributions and top-cited articles were also investigated. Results: The JBM 2020 IF was 2.17 in the WoS. The 2020 SJR in Scopus was 0.334, with a ranking of 165/219 (75.3%) in the Endocrinology, Diabetes, and Metabolism category. The 2020 KCI was 0.42. Of 263 articles, 260 were citable (98.9%), and of 176 original articles, 15 (8.5%) were supported by research grants. The total citation of JBM has increased from 16 in 2014 to 141 in 2020; however, its KCI remained stationary from 0.29 in 2015 to 0.42 in 2020. Conclusions Currently, JBM is increasingly cited by international researchers than Korean researchers, indicating that the journal’s content is valued at an international level. Its inclusion in PubMed Central appears to have increased its international relevance; however, publishing English-only articles may hinder its use domestically. Therefore, efforts should be made to increase citation rates and enhance domestic readership.

The inhalation of volatile substances has becoming a popular fad among adolescents in the world. Glue sniffing is associated with injury of nervous system, liver and kidney. And rarely abnormality of blood and bone marrow suppression can develop. The main components of volatile substances that cause hematologic abnormality is thought to be benzene, toluene, and xylene. A 24 year-old male was admitted to our hospital due to gum bleeding. He was a chronic glue and organic solvents sniffer for 6 years, and quit sniffing 1 year before admission. He had no specific drug history. On admission, CBC was as follows: WBC 2,500/mm3; hemoglobin 8.9g/dl; hematocrit 25.1%; platelet 2,000/mm3. Bone marrow biopsy showed severe hypocellular marrow compatible with aplastic anemia. We report a case of aplastic anemia after habitual sniffing of glue and volatile substances with brief review of the literature.

While it is reasonably well known that certain dental procedures increase the temperature of the tooth's surface, of greater interest is their potential damaging effect on the pulp and tooth-supporting tissues. Previous studies have investigated the responses of the pulp, periodontal ligament, and alveolar bone to thermal irritation and the temperature at which thermal damage is initiated. There are also many in vitro studies that have measured the temperature increase of the pulp and tooth-supporting tissues during restorative and endodontic procedures. This review article provides an overview of studies measuring temperature increases in tooth structures during several restorative and endodontic procedures, and proposes clinical guidelines for reducing potential thermal hazards to the pulp and supporting tissues.

Seborrheic dermatitis is a chronic recurrent inflammatory disorder presumed to be caused by increased sebaceous gland secretion, metabolic changes in the cutaneous microflora, and changes in the host immune function. Stellate ganglion block (SGB) is known to increase the blood flow rate without altering the blood pressure, heart rate, or cardiac output, to stabilize hypertonic conditions of the sympathetic nerves, and to affect the endocrine and immune systems. It is used in the differential diagnosis and treatment of autonomic nervous system disorders of the head, neck, and upper limbs. The authors report the first case of successful treatment of a patient with seborrheic dermatitis through repeated SGB trials.

PURPOSE: The pedicle of transverse rectus abdominis myocutaneous(TRAM) flap and deep inferior epigastric arterial perforator flap is deep inferior epigastic artery (DIEA) and accurate anatomic knowledge about perforator of DIEA is very important for the elevation of these flap. The authors investigated a detailed vascular network of perforator of DIEA in Koreans. METHODS: 24 fresh cadavers were studied. Among them, 15 were examined based on the plain X-ray examination for the distribution and location of perforator of DIEA. And 9 fresh cadavers were examined based on the 3-dimensional computed tomography(CT) study for the distance between ending point of perforator of DIEA and mother artery, the distance between most medial mother artery and midline, the distance between most lateral mother artery and midline, and the running type of perforators of DIEA. RESULTS: Based on the plain X-ray examination, suitable(external diameter> or =0.5mm) perforators of DIEA are located between the level of umbilicus and 8cm below it. Based on the 3D-CT study, average distance between the ending point of perforator of DIEA and the mother artery is 30.26mm on the left, 28.62mm on the right, respectively. The average distance between most medial mother artery and midline is 17.13mm on the left, 15.76mm on the right, respectively. The average distance between most lateral mother artery and midline is 56.31mm on the left, 50.90mm on the right, respectively. The main running course of suitable perforators of DIEA is type a, which is a direct musculocutaneous perforator vessel from main vascular axis passing outward to join the subdermal plexus, directly. CONCLUSION:3-dimensional computed tomography study as well as plain X-ray examination provided more accurate and detail informations about perforators of DIEA in Koreans. These informations will help us understand the detailed vascular anatomy and operation with ease and safe in the lower abdomen of Koreans.

This case report involves tracheal intubation using i-gel(R) in combination with a lightwand in a patient with a difficult airway, classified as Cormack-Lehane grade 3. I-gel(R) was used during anesthesia induction to properly maintain ventilation. The authors have previously reported successful tracheal intubation on a patient with a difficult airway through the use of i-gel(R) and a fiberoptic bronchoscope. However, if the use of a fiberoptic bronchoscope is not immediately available in a patient with a difficult airway, tracheal intubation may be performed by using i-gel(R) and a lightwand in a patient with difficult airway, allowing the safe induction of anesthesia.

Forty-nine cadaver dissections (male 30, female 19) were performed to identify the shape and size of rectus abdominis muscle and the distribution of vessels in Korean for flap surgery. The total length between xiphoid process and pubic symphysis of male is 375.9+/-41.8 mm and female is 339.4+/-39.1 mm. But the length between umbilicus and pubic symphysis of male and female did not show significant difference. The three tendinous intersections are 61.2%, the 4 intersections are 35.7%, and 2 intersections are 3.1%. The most of first, second and third intersections had the most complete intersection. The most of fourth intersection had the most fragmentary intersection. The external diameter of superior epigastric artery is 1.4+/-0.3 mm, and inferior epigastric artery is 2.6+/-0.6 mm. The percentage of superior epigastric artery that goes into the medial 1/3 region of rectus abdominis muscle is 52%, middle 1/3 region is 38%, lateral 1/3 region is 2% and 2 stem goes into the muscle is 8%. The length between the origin of inferior epigastric artery and the point of semilunar line met inferior epigastric artery is 41.1 mm in male and 38.8 mm in female.

BACKGROUND: Dexmedemomidine, a highly selective alpha-2 adrenoreceptor agonist has an analgesic and sedative effect without causing respiratory depression. In this study, we compared the duration of brachial plexus block (BPB), the time at which the patient first feels pain after performing BPB, the need for use of analgesics, and the occurrence rate of complications while continuous infusion with dexmedetomidine was used for sedation in patients undergoing BPB, to a control group, who were only infused with normal saline. METHODS: BPB was performed in 48 patients scheduled for upper limb surgery. Infraclavicular approach was provided with 40 ml of 1.5% mepivacaine and 200 microg of epinephrine using nerve stimulator. After verification of successful block, dexmedetomidine group received dexmedetomidine (loading dose 0.1 microg/kg/min for the first 10 minutes followed by a maintenance dose of 0.005 microg/kg/min as required to maintain bispectral index 60-80). In the control group, normal saline was infused at a rate of 10 ml/hr. The duration of BPB, the time at which the patient first feels pain after performing BPB, frequency of complication, and the use of analgesics of the both groups were checked. RESULTS: The motor and sensory block duration, and the time at which the patient first feels pain after BPB were longer in the dexmedetomidine group compared to the control group. And the need for analgesics were less in the dexmedetomidine group. CONCLUSIONS: Intravenous administration of dexmedetomidine prolongs the duration of BPB.

BACKGROUND: Lidocaine has been used widely to prevent propofol injection pain. Various methods of administration exist, such as lidocaine premixed with propofol or lidocaine pretreatment using a tourniquet, but it is unclear which method of lidocaine administration is more effective for the prevention of injection pain of propofol LCT/MCT. The purpose of this study was to compare pretreatment of lidocaine with a tourniquet and a premixed injection of lidocaine to prevent injection pain of propofol-LCT/MCT. METHODS: Patients were randomly allocated into the pretreatment group (n = 117) or the premixed group (n = 117). The pretreatment group was pretreated with 2 ml of lidocaine 2%, held with a tourniquet, before propofol-LCT/MCT injection. The premixed group was injected with a premixed solution of propofol-LCT/MCT and 2 ml of lidocaine 2%. To evaluate the incidence and severity of pain, spontaneous verbal expressions of pain, movement of hand, frowning, and moaning were recorded, and the patients were asked to recall their pain with the visual analogue score (VAS) 30 minutes after awakening from anesthesia. RESULTS: Overall, injection pain occurred in 13.7% of the pretreatment group and 15.4% of the premixed group, without any statistical difference (P = 0.71). There was no difference in spontaneous verbal expressions of pain, movement of hand, frowning, and moaning between the two groups. The pain intensity (VAS) also showed no difference between the two groups (P = 0.49). CONCLUSIONS: Pretreatment of lidocaine with a tourniquet showed no more benefit to prevent injection pain of propofol LCT/MCT compared to a premixed injection with lidocaine.
