PURPOSE: To compare the effect of medial rectus recession in consecutive esotropes who had previous monocular medial rectus resection and lateral rectus recession and in non- accommodative esotropes (NAET) with small angle of deviation who had no prior operation. METHODS: We studied the results of unilateral medial rectus recession at postoperative 2 and 6 months in 7 consecutive esotropes and 19 NAET with deviation angle around 20 PD, and analyzed the corrected amount for 1 mm medial rectus recession. We regarded deviated angle of+/-8 PD at orthophoria as successful operation. RESULTS: The abosolute value of remained deviation in consecutive esotropes and NAET were 4.86+/-5.67 PD and 9.05+/-3.95 PD at postoperative 2 months, and 5.42+/-7.89 PD and 8.26+/-4.45 PD at postoperative 6 months, respectively. There were significant differences between at postoperative 2 and 6 months (p<0.05). The success rates in consecutive esotropes and NAET at postoperative 2 months were 86% and 42%, and 71% and 47%, respectively at postoperative 6 months, which were no significant differences (p>0.05). The average amount of corrected deviation for 1 mm recession at postoperative 6 months was 5.84 PD in consecutive esotropes and 2.97 PD in NAET, which were significant differences (p<0.05). CONCLUSION: Unilateral medial rectus recession in consecutive esotropes may be a useful and first choice of operation procedure when considering second operation. The amount of correction for 1 mm medial rectus recession is larger in consecutive esotropes than in NAET, possibly due to previous resection of medial rectus or release of fat adhesion. Therefore the amount of medial rectus recession in consecutive esotropia should be determined after considering the degree of abduction and operative findings.

An epidemiological investigation was carried out at Yongin, Kyungkido, South Korea to determine the prevalence of symptoms of temporomandibular disorders and parafunctional habits in adolescent aged 16, 17 and 18 years. 2,098 students(male 507, female 1,591) were randomly selected and investigated with the questionnaire. The results were obtained as follows. 1. The prevalence of symptoms of temporomandibular disorders was 80.9% total, 77.3% for male and 82.0% for female with significance between male and female(P<0.05). 2. The prevalence of symptoms of temporomandibular disorders was gradually increased according to increasing age with significant difference among ages(P<0.01) 3. The most frequent symptom in the temporomandibular disorders is pain on chewing(65.9), and then clicking(50.7%), pain on mouth opening(41.8%), and pain on TMJ(36.8%). 4. There was little corelationship between clenching habits and symptoms of temporomandibular disorders(r=0.166), and also between bruxing habit and those(r=0.057).

Patau syndrome, a trisomy of number 13 chromosome, is a rare congenital chromosomal anomaly accompaing many abnormalities of cardiovascular and central nervous system, kidney and extremity, face and eye. We experienced a case of Patau syndrome in newborn infant who had bilateral microphthalmia, microcornea, corneal opacity, iris coloboma, cataract, dislocated lens, spherophakia, retianl fold and dysplasia, which are typical ocular anomalies of this syndrome previously described overseas but not reported in domestic. So, we report this case with a review of the literatures.

Preoperarive measurement of strabismic angle is most important procedure in determining the amount of surgery.But measured angles are not always the same at each examination, which is quite a steress to both the operator and the patient because additional examination has to be done for accurate determination of surgical amount and also because the confidence for planned amount of surgery may be reduced.Therefore we investigated the variance of preoperative measurements and evaluated the necessity of repeated examinations. We compared the variance of measurement and investigated the bias and reliability of repeated examinations, from 104 patients who were examined initially by a resident at first visit and examined repeatedly at least 3 times before operation by a specialist.Also, the degree of variance in measurement and its relation with postoperative result were evaluated. The differences in measurement between resident and specialist was average 2.37 prism diopters, which was not significant on reliability analysis.Also, there were no significant differneces among 3 measurements by specialist. The degree of variance decreased with increasing age and the larger the degree of variance in measurement, the larger the deviation which may be remained postoperatively. The results suggest that the angle of deviation measured by resident is reliable and repeated measurements do not differ significantly[p>0.05], and also confirms that the variation of these measurements is an important factor which can influence postoperative results.

The significant advance in the development of molecular-targeting drugs has made an evaluation of Her-2, EGFR, and cyclin D1 an important clinical issue in breast cancer patients. This study compared the Her-2, EGFR, and cyclin D1 status of primary tumors as well as their matching lymph node metastases using immunohistochemistry (IHC) and chromogenic in situ hybridization (CISH) in 73 breast cancer patients. Her-2, EGFR, and cyclin D1 protein showed a concordance between the primary lesion and the metastatic regional lymph nodes in 82%, 90%, and 63%, respectively. CISH also revealed 92%, 93%, and 85% concordance in the gene amplification status of Her-2, EGFR, and cyclin D1, showing a reasonable agreement between primary tumors and metastatic regional lymph nodes. Although a statistically significant agreement was found in Her-2 expression, a relatively high discordance rate (18%) raises a little concern. Our findings suggest that the Her-2 status can be reliably assessed on primary tumor but a possible difference can be found in Her-2, EGFR, and cyclin D1 status between the primary and the metastatic sites and this possibility should be concerned in patients considering molecular targeted therapy or patients with progress of disease.

PURPOSE: To compare the macular choroidal thickness in patients with thyroid-associated ophthalmopathy (TAO) with those with normal tension glaucoma (NTG). METHODS: A total of 70 normal eyes, 74 eyes with TAO and 60 eyes with NTG were enrolled in this study. All patients underwent spectral-domain optical coherence tomography (SD-OCT) (Cirrus HD-OCT, Carl Zeiss Meditec Inc., Dublin, CA, USA). Macular choroidal thickness was assessed using enhanced depth imaging. The average macular choroidal thickness was defined as the average value of three measurements: at the fovea and at the points located 1.5 mm in the nasal and temporal directions from the fovea. Generalized estimating equations were used to uncover factors affecting the average macular choroidal thickness. RESULTS: The average, superior and inferior quadrant retinal nerve fiber layer thicknesses were significantly thinner in the NTG group compared with the TAO and control groups (p < 0.001). The average macular choroidal thickness of the TAO group, NTG group and controls was 281.01 ± 60.06 µm, 241.66 ± 55.00 µm and 252.07 ± 55.05 µm, respectively, which were significantly different (p = 0.013). The subfoveal, nasal and temporal side choroidal thicknesses were significantly thinner in the NTG group compared with the TAO group (p = 0.014, 0.012 and 0.034, respectively). Subjects with TAO were associated with a thicker average macular choroidal thickness compared with the NTG group after adjusting for age, sex, spherical equivalent and intraocular pressure (β = 32.61, p = 0.017). CONCLUSIONS: Macular choroidal thickness was significantly thicker in patients with TAO compared with those with NTG. Further evaluation is required to determine if a thick choroid in subjects with TAO has any role in glaucomatous optic neuropathy.

Ribonucleic acid (RNA) has potential use in forensic science for the determination of postmortem interval. We report the first study on serial sampling of messenger RNA (mRNA) from surgical specimens to determine if there is a correlation between mRNA quantity and elapsed time. Skin tissues were collected from modified radical mastectomy specimens. After a defined period of time, bisected skin sections were cut and frozen in liquid nitrogen. Serial collection of the specimens was conducted, and frozen sections were obtained from all samples. Quantitative real-time reverse transcription-polymerase chain reaction was performed using the extracted RNA to measure the transcriptional activity of 2 selected housekeeping genes. The selected loci were mRNA sequences that exhibited time-dependent quantitative changes in a previous study. We collected 44 samples from 9 different patients, with 3-10 samples collected per patient. The amount of mRNA transcripts present in the serial samples showed a weak time-dependent correlation trend only in some cases. Further studies to evaluate different target mRNA sequences are necessary, as is exploration of additional methods to evaluate mRNA transcript degradation.

We report an extraordinary case of diffuse large B-cell lymphoma arising in a cystic necrotic mass in a 35-year-old man who presented with a soft tissue mass at the site of previous surgery. A benign mass was surgically removed 17 years ago, after which a cystic lesion gradually developed at the same site. The resected mass appeared as a thick-walled cyst filled with brown necrotic and hemorrhagic material. On microscopic examination, the cyst wall was primarily necrotic tissue with some aggregates of large atypical lymphoid cells. These atypical cells were diffusely positive for CD20 and showed a high proliferation index, Epstein-Barr virus positivity, and clonal rearrangement of the immunoglobulin gene. His present condition was diagnosed as Epstein-Barr virus-associated diffuse large B-cell lymphoma arising from chronic inflammation. It is important to be aware of the clinical manifestations and histological features of this rare disease in light of diagnosis and treatment.

We herein describe a 70-year-old woman who presented with respiratory failure due to extensive lung adenocarcinoma. Despite advanced disease, care in the intensive care unit with ventilator support was performed because she was a newly diagnosed patient and was considered to have the potential to recover after cancer treatment. Because prompt control of the cancer was needed to treat the respiratory failure, empirical treatment with an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor was initiated before confirmation of EGFR-mutant adenocarcinoma, and the patient was successfully treated. Later, EGFR-mutant adenocarcinoma was confirmed.

Journal of the Korean Ophthalmological Society 2023;64(2):154-157
Purpose:
To report the first domestic case of orbital eccrine hidrocystoma.Case summary: A 40-year-old man visited our clinic after an orbital mass was discovered in the left eye. Orbital magnetic resonance imaging showed a well-defined 1 cm mass on the superomedial side of the orbit, slightly posterior to the globe. The mass was excised completely without rupture through an incision to the upper eyelid skin. The mass appeared more like a cyst than a hemangioma. The diagnosis of eccrine hidrocystoma was confirmed histopathologically. The patient recovered and there was no recurrence at the 6-month follow-up.
Conclusions
Although orbital eccrine hidrocystoma is very rare, it should be included in the differential diagnosis of orbital tumors.
