Lemierre Syndrome Caused by Streptococcus constellatus Mono-Infection: A Case Report
박다희,이진춘,노환중 대한이비인후과학회 부산,울산,경남 지부회 2023 임상이비인후과 Vol.34 No.4
The onset of Lemierre syndrome is marked by oral or oropharyngeal infection, especially a parapharyngeal abscess. Pa- tients having Lemierre syndrome often do not present with severe throat symptoms, making clinical diagnosis difficult. The prognosis is poor if the patient is not promptly diagnosed and actively treated. Herein, we describe a patient who developed Lemierre syndrome following a peritonsillar abscess. Blood tests revealed septicemia and computed to- mography showed an internal jugular vein thrombosis. The patient was immediately underwent incision and drainage and Streptococcus constellatus was cultured. Antibiotics were administered for a month postoperatively and the patient recovered successfully. This case represents successful outcome of Lemierre syndrome with Streptococcus constellatus mono-infection, which is a relatively rare course of Lemierre syndrome.

This study examines overall family lifehabit of the lower grades in elementary school, and based on general background and food, clothing and shelter in family, it looks into relevancy with an atopic dermatitis. The participants of the study were male and female lower grade students ranged from ages 7 to 10 in Cheong-ju region; 218 patients who were diagnosed with atopic dermatitis by medical examination of dermatologists and 259 normal children who didn’t have the disease and were without other skin complaints. The data obtained from the survey results are as follows: First, it is found that cesarean or induced labor increase an atopic dermatitis compared to natural childbirth (p<.05), and colostrums and breast-feeding as well as preference of meat diet instead of vegetarian affect the atopic dermatitis (p<.01). Second, there were significant differences in degrees of skin symptoms according to ages, scope of intrusion, and in the result of comparison of subjective symptoms, degrees of skin symptoms by ages. Third, in the comparison of dietary habits those who have breakfast every day have little chance to have the atopic dermatitis (p<.01), and frequent late-night meal and dining out cause the disease (p<.001). Fourth, in the comparison of housing life, those who raise pets tend to have the atopic dermatitis, and the use of an electric pad, heater, and a hot-air blower as well as the presence of electric device in children’s room cause the disease; cockroach, ants, and mold also affect the mobility rate of the atopic dermatitis. It is also known that the number of washing bedclothes, ventilation of inside air, the use of hood when cooking and environment of surrounding of houses affect the rate. Therefore, the atopic dermatitis and life patterns of children have significant relations. Also, it is also necessary to foster experts in an atopic dermatitis or have institutional efforts of public institutions or regional ones to reinforce education on it so that children and parents can raise of their quality of life.

Background and Objectives: A thyroidectomy is an operation that can lead to life-threatening complications. The drainage after thyroidectomy has been suggested to prevent these complications. The aim of this study is to evaluate the feasibility and safety of hemithyroidectomy without drains. Materials and Methods: This retrospective casecontrol study included all hemithyroidectomies with central neck dissection (CND) or without CND performed at the single hospital from January 2015 to December 2017. The demographic data, operation times, hospital days, and postoperative complications were evaulated. Results: During the study period, Two hundred–twenty patients who were underwent hemithyroidectomy for benign or well differentiated carcinoma. The majority of patients were female (N=153, 69.5%). Drains were inserted postoperatively after 102 surgeries (46.4%) compared to 118 surgeries (53.6%) without drains. There were no significant difference in seroma, hematoma, infection, vocal cord palsy, hypocalcemia between drain group and without drain group(p>0.05). However, there were significant difference in operation times and hospital days between drain group and without drain group (p<0.001, p<0.001, respectively). Conclusions: The tumor size in drain group tended to be relatively large, and hospital days and operation times were significantly increased. However, there were no differences in postoperative complications between drain and without drain groups

Thyroid surgery can cause many complications, but recurrent laryngeal nerve palsy is the most important. Therefore, many efforts have been tried to avoid recurrent laryngeal nerve palsy. Among them, intraoperative neuromonitoring (IONM) is one of the useful tools to find nerves and avoid nerve palsy during surgery. There are various methods, but the method of directly monitoring the movement of the vocal cords using an electromyography tube was introduced first. After that, a method of increasing the signal accuracy by using a pressure sensor and an accelerometer sensor was also introduced. In addition, a needle is directly pierced into the thyroid cartilage or an electrical signal is measured by attaching a sensor to the skin in front of the thyroid cartilage. Various methods of IONM are being tried and studied, and efforts to help find nerves through IONM are continuing. It is expected that overall surgical complications will be reduced by preserving nerves, avoiding changes in voice and swallowing disorders, and reducing the need for tracheostomy due to bilateral vocal cord palsy.

The olfactory neuroblastoma (ONB) is a rare malignant tumor that arises in the nasal cavity and paranasal sinuses. The most common treatment is the craniofacial resection, but recently endoscopic resection has been used as an initial treatment to reduce complications. In addition, depending on the stage of the disease, radiation therapy or chemotherapy can be performed before or after surgery. ONB can also recur, showing two patterns of recurrence: local recurrence and distant metastasis to cervical lymph nodes and lungs. Local recurrence is usually treated with craniotomy, but this is an invasive treatment method that can cause various complications. Therefore, non-invasive treatment methods such as stereotactic radiation therapy are now being considered. The authors report a recurred ONB case successfully treated with Gamma knife radiosurgery without craniofacial resection, as the patient showed delayed bilateral cervical lymph node metastasis and suspected recurrent intracranial invasion after treatment.

메탈폼은 매우 많은 기공을 포함하는 세포상 구조를 갖는 고체금속을 일컫는다. 특히 관통 기공 같은 개기공들은 고온용 필터 및 촉매 지지체 등으로 산업적으로 많이 사용되고 있다. 본 연구에서는 슬러리 코팅공정으로 90% 이상의 기공율과 2 mm 이상의 기공크기를 갖는 Fe 폼을 제조하였다. 이때 Fe 분말과 $Fe_2O_3$ 분말의 혼합비를 달리하여 기공율과 기공크기를 제어하였다. 이를 위해 우선 분말, 증류수 및 폴리비닐알콜(PVA)를 균일하게 혼합하여 슬러리를 제조하였다. $Fe_2O_3$ 분말의 혼합 비율이 증가할수록 PU 폼에 코팅된 슬러리의 양이 증가한 반면 Fe 폼의 수축 및 기공율은 각각 감소하였다. Metal foams have a cellular structure consisting of a solid metal containing a large volume fraction of pores. In particular, open pores which are penetrable pores are necessary for industrial applications such as in high temperature filters and as support for catalysts. In this study, Fe foam with greater than 90% porosity and 2-mm pore size was successfully fabricated using a slurry coating process and the pore properties were characterized. The Fe and $Fe_2O_3$ powder mixing ratios were controlled to produce Fe foam samples with different pore sizes and porosity. First, the slurry was prepared through the uniform mixing of powders, distilled water, and polyvinyl alcohol(PVA). The amount of slurry coated with the PU foam increased with increasing $Fe_2O_3$ mixing powder ratio, but the shrinkage and porosity of the Fe foams decreased, respectively, with increasing $Fe_2O_3$ mixing powder ratio.
