1.Experience, educational needs and perception of dentine hypersensitivity of dental hygienists
Journal of Korean Academy of Oral Health 2023;47(2):85-89
Objectives:
This study investigates dental hygienists’ experience, education, and awareness of dentin hypersensitivity. Its purpose is to provide a basis for the development of preventive procedures and educational materials for dentin hypersensitivity.
Methods:
After distributing the questionnaire, Oral health characteristics of dental hygienists and the general public were investigated. In addition, the experience of dentin hypersensitivity according to general characteristics and the need for education were confirmed. The collected data were analyzed by frequency analysis, descriptive statistical analysis, unpaired t-test, and one-way ANOVA.
Results:
There was no difference in the experience of dentin hypersensitivity according to oral health-related or general characteristics in the dental hygienist group. In terms of oral health, there was a difference in educational requirements for dentin hypersensitivity for ‘family support for oral health’.
Conclusions
The experience of dentin hypersensitivity in this study can be used as data for the development of a Korean dentin hypersensitivity experience questionnaire. The educational requirements and perception of dentine hypersensitivity will help develop educational materials from the patient’s perspective. Moreover, they will be essential for practical education on dentine hypersensitivity in dental hygiene and educational processes.

Changes in CTB labeled motor neurons of the spinal cord were observed after the induction of peripheral neuropathy by ligation of the tibial nerve. Rats were anesthetized and the tibial nerve was ligated with 3-0 silk. The rats were separated into three groups based on the length of time the tibial nerve was ligated (1, 2, or 4 weeks). After the ligation procedures were complete, the tibial nerve stumps were soaked in CTB solution. Tibial nerve segments and the spinal cord were then observed. In the control and experimental groups, CTB-labeled neurons formed a discrete population that was concentrated primarily at the L5 level, while the contributions from L4 and L6 were minor. According to the distributions, CTB-labeled neurons were divided into rostral and caudal groups. A selective decrease of CTB-labeled neurons was observed only in the caudal group, extending from the rostral L5 to one-half of the rostral L6. The total numbers of CTB-labeled motor neurons were 2,160+/-169.3, 1,002+/-245.1, 587.5+/-346.5, and 1,728+/-402.6 in the control group, 1 week group, 2 week group, and 4 week group, respectively. The selective decrease of CTB-labeled neurons in the caudal division was responsible for the decrease in the total number of labeled neurons in all groups. Following peripheral neuropathy caused by ligation of the tibial nerve, CTB-labeled neurons in the spinal cord decreased selectively. These results may provide important neuroanatomical data regarding the effects of peripheral neuropathy by ligation of the tibial nerve.

Malakoplakia is a rare chronic granulomatous disease found in the genitourinary tract, mainly. It is considered to be related to immunosuppression and/or infectious processes. We would like to present an operative case of cecal malakoplakia in a patient with a history of surgical resection and chemotherapy for cervical cancer. A 74-year-old female patient visited our hospital for 1-year follow-up after operation and chemo-radiotherapy for cervical cancer. An infiltrative mass of 6 cm, between the cecal base and the right psoas muscle, was observed on computed tomography. An ileocectomy was performed for diagnosis. Histopathologic examination revealed cecal malakoplakia. After surgery, based on previous reports, antibiotics therapy was added. Then the patient was discharged and treated in the outpatient clinic. To our knowledge, a rare case has been described of cecal malakoplakia during observation after surgery and chemo-radiotherapy for cervical cancer. Malakoplakia is known to be related to immunosuppressive condition. Therefore, our case suggests that close observation should be made in patients on immunosuppressive condition, such as chemotherapy.

We evaluated the effects of guanosine 5′-monophosphate (GMP)-chelated calcium and iron (CaFe-GMP) on health and egg quality in layers experimentally infected with Salmonella Gallinarum. In this study, a CaFe-GMP feed additive was added to a commercial layer feed and fed to layers over a four-week period. All were inoculated with Salmonella Gallinarum. Body weight, mortality, clinical symptoms, and poultry production including feed intake, egg production, egg loss, and feed conversion rate were observed, and Salmonella Gallinarum was re-isolated from the liver, spleen, and cecum of the layers. All tested internal organs for the CaFe-GMP additive group exhibited significantly lower re-isolation numbers of Salmonella Gallinarum and less severe pathological changes than those in the control group, indicating that the CaFe-GMP feed supplement induced bacterial clearance and increased resistance to Salmonella Gallinarum. Additionally, due to the inhibitory action of CaFe-GMP on the growth of Salmonella Gallinarum, the CaFe-GMP additive group exhibited better egg production, including a higher laying rate and fewer broken eggs. The results suggest that a 0.16% CaFe-GMP additive may help prevent salmonellosis in the poultry industry.

PURPOSE: To analyse complications and to review usefulness of large needle(18G) in percutaneous transhepatic biliary drainage(PTBD). MATERIALS AND METHODS: 46 patients underwent PTBD in 52 occassions using large needle. 44 of 46 patients had either definite or suspicious malignant biliary obstruction, and most patients were poor in general dondition. Complications were classified as acute type if developed within 30 days and as delayed type if developed after 30 days. Acute type was subdivided into severe and mild forms. RESULTS: Severe forms of complications were death(5.8%), septicemia(3.8%), and bile peritonitis(1.9%). There were not different from the rate of complication in PTBD using fine needle but the procedure was much more simple. CONCLUSION: We PTBD using large neddie is a simple and safe procedure for prompt bile decompression.

There are few reports in the literature of complete obstruction of the vertebral artery (VA) due to an electric screw driver bit penetration through the neural foramen into the spinal canal with Brown-Sequard syndrome (BSS). A 25-year-old man was admitted to the emergency department with a penetrated neck injury by an electric screw driver bit after a struggle. The patient presented the clinical features of BSS. Computed tomography scan revealed that the electric screw driver bit penetrated through the right neural foramen at the level of C3-4, and it caused an injury to the right half of the spinal cord. Emergent angiography revealed VA dissection, which was managed by immediate coil embolization at both proximal and distal ends of the injury site. After occlusion of the VA, the electric screw driver bit was extracted under general anesthesia. Bleeding was minimal and controlled without difficulties. No postoperative complications, such as wound dehiscence, CSF leakage, or infection, were noted. Endovascular approaches for occlusion of vertebral artery lesions are safe and effective methods of treatment.

The incidence of bacteremia in human immunodeficiency virus (HIV)-infected patients is significantly decreased by highly active antiretroviral therapy (HAART). However, bacteremia remains a major cause of morbidity and mortality in HIV-infected patients. A 43-year-old male who had fever and cough for 1 week presented to the emergency room. He was diagnosed with acquired immunodeficiency syndrome combined with atypical pneumonia and started on antibiotics plus HAART. After 3 days, Streptococcus pneumoniae was grown in blood cultures. Three weeks later, acid-fast bacilli cultures of blood and bronchoalveolar lavage fluid grew Mycobacterium avium complex (MAC); hence, the patient was treated with antimycobacterial drugs. HIV-infected patients with persistent fever despite administration of appropriate antibiotics should be examined for simultaneous infection by other organisms, such as nontuberculous mycobacteria. We report a case of simultaneous detection of MAC and S. pneumoniae in the blood of a treatment-naïve HIV-infected patient.

Vibrio cholerae (V. cholerae) serotype O1 or O139 is the etiological agents of cholera. These bacteria are responsible for gastrointestinal infections or more rarely bacteremia in patients with an underlying disease, leading to life-threatening complications. A 73-year-old man presented to the hospital with fever and vomiting. Blood cultures grew non-O1/non-O139 V. cholerae. In this case, clinical improvement and microbiological eradication were achieved due to early appropriate antibiotic therapy. These results suggest that early antibiotic therapy allowed a good outcome in diabetic patient infected with V. cholerae . To our knowledge, this is the first case of primary bacteremia caused by non-O1/non-O139 Vibrio cholera in Korea.

Endometriosis is defined as the presence of endometrial tissue outside the uterus and located usually within the pelvis. It may be detected as a rare complication associated with surgery. Endometriosis following obstetric and gynecologic procedure, which is localized mostly in the surgical scar including Cesarean section scar, hysterotomy scar, trocar scar, Bartholin cyst exision scar, or episiotomy scar, may caused by implantation of endometrial gland and stroma. Endometriosis developing after hysterectomy, especially, is a quite rare condition except a recurrent disease. We have experienced a case of a 47-year-old woman who had diagnosed ovarian endometriosis two years after laparoscopically assisted vaginal hysterectomy for a large leiomyomatous uterus with no evidence of endometriosis, so we report this case with a brief review of literature.
