3.A Toxic Anterior Segment Syndrome-like Ocular Inflammatory Reaction after COVID-19 Vaccination
Journal of the Korean Ophthalmological Society 2022;63(7):625-629
Purpose:
We report a case with bilateral, ocular inflammatory adverse reactions developing a few hours after COVID-19 vaccination.Case summary: A 70-year-old woman complained of headache and sudden visual impairment (both eyes) a few hours after COVID-19 vaccination (Astrazeneca). She had undergone bilateral cataract surgery 4 days before vaccination and her eyesight was good immediately after surgery. The best-corrected visual acuities (BCVA) were 0.2 and 0.1 in the right and left eyes, respectively. Diffuse corneal edema, anterior chamber reactions, inflammatory fibrinoid membranes on the anterior surfaces of the intraocular lenses (IOLs), and cystoid macular edema were observed in both eyes. The anterior chamber and IOL fibrinoid reactions much improved 7 days after the prescription of topical and oral corticosteroids. The aqueous humor polymerase chain reaction was positive for varicella zoster virus (VZV) in both eyes. The BCVA improved to 20/30 in the right eye and 20/50 in the left eye after 3 months of additional treatment. However, the cystoid macular edema did not improve.
Conclusions
In patients with a history of herpes zoster infection, adverse ocular inflammatory reactions associated with VZV may occur immediately after COVID-19 vaccination.

OBJECTIVE: In the human body the embryo initially gmws in the fallopian tube which is maintained in an 3-8% O2 concentration environment, and various substances such as growth factors and antioxidants present in tbe tubal fluid assists in maintaining a healthy environment for embryo development. But in IVF programs embryo cultures are conducted in incubators with 21.9% O2 and 5% CO2 condition, and such high oxygen concentrations have been reported to increase the production of oxygen free radicals within the embryo and is detrimental to the growth and development of the embryo. The objective of this study, therefore, is to determine the culture conditions which will decrease oxygen free radical production and thereby minimize the injury to the embryo. METHODS: Six to eight week old ICR strain mice embryos were cultured in 5% or 21.9% O2 conditions and in culture media to which inaement concentrations of superoxide dismutase (SOD) had been and the H2O2 concentration within the embryo, embryo developmental rate, and degree of fragmentation of the embryos was investigated. RESULTS: The control gmup embryos which were cultured in 21.9% O2 condition without addition of SOD showed developmental arrest at the 2-cell stage or fragmentation, while those cultured in 21.9% O2 condition with addition of SOD showed development to the blastocyst stage with deaeased fragmentation. In particular, the blastulation and fragmentation rates were the lowest in the group to which 500 IU/ml of SOD was added, but in the 5% O2 enviranment group many embryos reached the blastocyst stage and with no difference in frapnentation with or without addition of SOD. The HO relative intensity (120.5+/-20.2) within the embryos cultured in 21.9% O2 environment without SOD was significantly higher than that (56.8+/-10.8) of group with SOD (p<0.05). As showing that in the 5% O2 environment group without SOD it was 43.8+/-7.8 and in the group with SOD it was 37.3+/-5.4, the H2O2 concentration within embryos cultured in 5% 02 condition was significantly lower those that of 21,9% 02 environment regardless of SOD addition (p<0.05). CONCLUSION: The optimal oxygen concentration in incubator for mice embryo cultures is that which is similar to the 5% 0 concentration in vivo. When 20% 02 incubators are routinely used, the addition of SOD to the culture media will decrease the H2O2 concentration within the embryos with subsequent improvement in development. The optimal concentration which should be used is thought to be 500 IU/ml. It is suggested that the use of the above method in human IVF-ET programs will lead to improved embryo quality and enhanced pregnancy rates.

PURPOSE: This study was conducted to perform a comparative analysis of the efficacy and safety of conventional transurethral resection of the prostate (TUR-P), transurethral resection in saline (TURIS), and TURIS-plasma vaporization (TURIS-V) when performed by a single surgeon for benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: The clinical data of 73 consecutive men who underwent conventional TUR-P (39), TURIS (19), or TURIS-V (15) for BPH were retrospectively analyzed. All procedures were carried out by a single surgeon between October 2007 and April 2010. The patients were assessed preoperatively and perioperatively and were followed at 1, 3, and 6 months postoperatively. Patient baseline characteristics, perioperative data, and postoperative outcomes were compared, and major complications were recorded. RESULTS: In all groups, significant improvements in subjective and objective voiding parameters were achieved and were sustained throughout follow-up. TURIS-V had the shortest operation time compared with conventional TUR-P and TURIS (p=0.211). TURIS-V significantly decreased procedural irrigation fluid volume, postoperative irrigation duration, catheter duration, and hospital stay compared with conventional TUR-P and TURIS. There were no significant differences between the groups in hemoglobin levels or serum sodium levels before and after the operations. There were three transfusions and four clot retentions in the TUR-P group, and one transfusion and one clot retention in the TURIS group. The TURIS-V group had no complications. CONCLUSIONS: TURIS and TURIS-V were effective for the surgical treatment of BPH in addition to conventional TUR-P. TURIS-V was not inferior to conventional TUR-P or TURIS in terms of safety.

Although severe hemolytic diseases of the newborn triggered by anti-M are very rare, anti-M alloantibodies have been known to be associated with a cause of multipie intrauterine death. Serological and hematological investigations have been reported on a woman who experienced four multiple intrauterine deaths due to anti-M. The mothers blood type was of group A, NN and the husbands cells were of group B, MN. In the serological examination at 9th week's gestation of the fifth pregnancy, anti-M antibodies were identified in her serum. The antibodies comprised IgM saline agglutinin at a titer of 16 at 4 degrees C and IgG agglutinin reacted in an indirect antiglobulin technique at a titer of 4 at 37 degrees C. She underwent high-dose immunoglobulin infusion therapy on a monthly program from 3rd month gestation and a total of 6 times of intravenous immunoglobulin was given. The anti-M titer did not rise during the pregnancy. She delivered a live girl by cesarean section at the 37th week because of a failure of induction. The childs blood type was of group O, MN. The child was discharged and developed normally.

Primary hyperparathyroicism is a state of hypersecretion of PTH by the parathyroid. The etiology has not been established. The three possible etiologies of piimary hyperparathyroidism and incidences are adencena(83%), hyperplasia(15%), and carcinoma(1~2%). Parathyroid carcinoma usually presents in the fourth decades. The hallmark preoperative signs are hypercalcemia(serum calcium 15mg/dl). Palpable neck mass and bane and renal disease. Patients may present with multiple signs and syrnptoms, including recurrent nephrolithiasis, peptic ulcers, mental change, less frequently, extensive bone resorption. However, with greater awareness of the disease and wider use of screening tests, including blood calcium determinations, the diagnosis is frequently made in patients who have no symptoms and minimal, if any, signs of the disease ather than hypercalcemia and elevated levels of parathyroid Hormone. An 38-years-old woman was admitted to the hospital due to pain on the left knee joint. We experienced full-brown symptom pertaining to hyperpara- thyroidism. Thus we report a case herein and also discuss clinical anifestation, histologic features and treatment.

Surgical intervention in the posterior maxillary region requires detailed knowledge of maxillary sinus anatomy and the possible anatomical variations. This study evaluated the incidence, location of maxillary sinus septa by using radiographic (panoramic radiography and computed tomography) findings and comparison of panoramic radography with CT in antral anatomical variation. This study was based on data from 70 sinuses in partial dentate maxilla. The sample consisted of 61 patients(25 women and 36 men, with ages ranging between 19 and 77 years and a mean age of 49.4+/-11.3 years) who were being treatment-planned to receive implant-supported restorations. First, the panoramic images were examined for the presence of antral septa by radiologist and examiner who don't know about CT findings. And incidence of antral septa was evaluated using an axial plane of CT image. The incidence of septa was compared between panoramic radiography and CT. The accuracy of the incidence was compared between radiologists and dentists. A total of 20 septa were found in 70 sinuses on CT image and the prevalence of one or more septa per sinus was found to be 28.6%. The assumed incidence of septa on panoramic radiography was 27.6%+/-2.2% in radiologist and 31.9%+/-5.8% in dentists. Erroneous diagnosis rate was 11.42% in radiologist and 15.96% in dentists. 40% of antral septa were located in the anterior(premolar) region, 30% of septa were located in the middle(first molar) and posterior(second molar) region separately. Prior to implant placement, it seems appropriate to consider panoramic radiography as a standard radiographic examination and periapical radiographs may be used to complete the findings in regions not sharply depicted in the panoramic radiograph. And cross-sectional imaging should be used in sites with severe bone loss and close proximity of the maxillary sinus.
