OBJECTIVE: The implantation failure after embryo-transfer (ET) is a major continuing problem in in vitro fertilization (IVF). This study was undertaken to determine the effectiveness of intravenous immunoglobulin for treatment of individuals experiencing repeated unexplained in vitro fertilization-embryo transfer (IVF-ET) failure. METHODS: A total of nine consecutive infertile patients who failed to become pregnant after previous IVF-ET replacing at least three or more normal developed embryos each were included in our study. During the subsequent new IVF-ET cycle, each women received intravenous immunoglobulin 500mg/kg before the embryo transfer. RESULTS: Only one implantation occurred. There were no remarkable side effects. A specific effect of intravenous immunoglobulin for patients with repeated IVF-ET failure could not be demonstrated. CONCLUSION: High-dose intravenous immunoglobulin may not be useful for patients with repeated failure of embryo transfer.

The etiology of neural tube defects, a category encompassing spina bifida, anencephaly and encephalocele, remains highly controversial and unclear, However, there is overwhelming evidence supporting a multifactorial etiology for this group of defects. Recent studies have shown that folic acid supplements taken periconceptionally can reduce a woman's risk of having a child with a neural tube defect. Qenetic screening could identify women who will require folic acid supplements periconceptionally to reduce their risk of having a child with a neural tube defects. Recently, we encountered two cases of recurrent anencephaly that had occurted in a same pregnant woman in our hospital. We report these two cases with brief review of the literatures.

As an effort to develop a rapid and sensitive diagnostic test, we produced previously a monoclonal antibody (MAb) specific to the lipoarabinomannan (LAM) antigen and used in a sandwich ELISA for detection of mycobacterial antigens in sputum. In this study, we attempted to improve the antigen detection assay by combination of af5nity-purified antibodies against Mycobacterium tuberculosis soluble antigen and anti-LAM MAb. With the new assay, the LAM antigen was detectable as low as 2 ng/ml, and none of 10 gram-negative and gram-positive organisms gave significant absorbance, thus indicating the specific detection of mycobacterial antigens. Sputum samples from 62 patients who were suspected having tuberculosis and from 37 healthy controls were examined. The sensitivity of the antigen detection assay ranged from 0% in the 1+ culture group to 78.8% in the 3+ culture group. When the results were combined, 15 of 24 culture-positive samples were antigen-positive, thus giving an overall sensitivity of 62.5%. The overall specificity was 96.0%, when all the culture-negative samples were combined. The results thus demonstrate that the antigen detection assay can provide a rapid supplemental information for the diagnosis of pulmonary diagnosis.

OBJECTIVES: Baso-apical gradients exist in various cochlear structures including medial olivocochlear (MOC) efferent system. This study investigated the cochlear regional differentials in the function and morphology of the MOC system, and addressed the functional implications of regional MOC efferent terminals (ETs) in the mouse cochlea. METHODS: In CBA/J mice, MOC reflex (MOCR) was assessed based on the distortion product otoacoustic emission in the absence and presence of contralateral acoustic stimulation. High, middle, and low frequencies were grouped according to a mouse place-frequency map. Cochlear whole mounts were immunostained for ETs with anti-α-synuclein and examined using confocal laser scanning microscopy. The diameters of ETs and the number of ETs per outer hair cell were measured from the z-stack images of the basal, middle and apical regions, respectively. RESULTS: The middle cochlear region expressed large, clustered MOC ETs with strong MOCR, the base expressed small, less clustered ETs with strong MOCR, and the apex expressed large, but less clustered ETs with weak MOCR. CONCLUSION: The mouse cochlea demonstrated regional differentials in the function and morphology of the MOC system. Strong MOCR along with superior MOC morphology in the middle region may contribute to ‘signal detection in noise,’ the primary efferent function, in the best hearing frequencies. Strong MOCR in spite of inferior MOC morphology in the base may reflect the importance of ‘protection from noise trauma’ in the high frequencies.

We report the case of a patient with gastric adenocarcinoma with multiple liver metastases. This patient showed complete remission for more than 68 months after S-1/cisplatin combination chemotherapy and radical total gastrectomy. The patient, a 63-year-old man, presented with dyspepsia and difficulty in swallowing. Endoscopic findings showed a huge ulcero-infiltrative mass at the lesser curvature of the mid-body, extending to the distal esophagus. Biopsy revealed a poorly differentiated tubular adenocarcinoma. An abdominal computed tomography scan demonstrated multiple hepatic metastases. S-1/cisplatin combination chemotherapy was initiated, and following completion of six cycles of chemotherapy, the gastric masses and hepatic metastatic lesions had disappeared on abdominal computed tomography. Radical total gastrectomy and D2 lymphadenectomy combined with splenectomy were performed. The patient underwent three cycles of S-1/cisplatin combination chemotherapy followed by tegafur-uracil therapy for 1 year. He remained in complete remission for more than 68 months after surgery.

Osteopathia striata with cranial sclerosis is a very rare sclerosing bone dysplasia that is characterized by the radiological appearance of longitudinal striations at the metaphysis of the long bones associated with cranial sclerosis. Here, we report a 10-month-old female infant and a 31-year-old male, who were diagnosed incidentally by showing longitudinal sclerotic lines symmetrically in the long bone ends and basal sclerosis of the cranium. The diagnostic linear striation was found not only in the long bones but also in the ribs and phalanges, which are very rare sites for striation. We discuss the radiology findings of osteopathia striata with the possible complication of cranial sclerosis.

A series of 119 Mycobacterium avium complex isolates were subjected to clarithromycin susceptibility testing using microplates containing 2,3-diphenyl-5-thienyl-(2)-tetrazolium chloride (STC). Among 119 isolates, 114 (95.8%) were susceptible to clarithromycin and 5 were resistant according to the new and the standard method. STC counts the low cost and reduces the number of procedures needed for susceptibility testing.

As the number of people vaccinated increases, people who complain of adverse reactions continue to occur. We experienced a case characterized by low blood pressure, persistent fever, edema due to increased systemic vascular permeability, and systemic inflammation confirmed by image and laboratory examinations after ChAdOx1 coronavirus disease 2019 (COVID-19) vaccination. The diagnostic criteria for multisystem inflammatory syndrome (MIS) in adults are known as fever of 3 days or more in adults, 2 or more mucocutaneous/ gastrointestinaleurologic symptoms, elevation of inflammatory markers, and clinical/ imaging diagnosis of heart failure. A 67-year-old man who was medicated for hypertension and diabetes was admitted complaining of fever, maculopapular rash, diarrhea, headache, chills, and dizziness 6 days after the first vaccination of ChAdOx1 nCoV-19 in Korea.The COVID-19 test was negative but with low blood pressure, leukocytosis, skin rash, pulmonary edema, and increased inflammation markers. His lab findings and clinical course were consistent with those of MIS after COVID-19 vaccination. He was medicated with methylprednisolone 1 mg/kg and diuretics and recovered rapidly. He was discharged after 2 weeks and confirmed cure at outpatient clinic. We report an MIS case after COVID-19 vaccination in Korea.
