The incidence of carcinoma of the small intestine is very low in children, and it is also known that the prognosis of this tumor in children is very poor. A case of adenocarcinoma in a 13-year-old girl arising in the jejunum is herein reported. The girl underwent a curative resection and is free of recurrence or metastasis 12 months after operation. This particular case is reported here with a review of the literature.

OBJECTIVES: Manganese is cytotoxic to the central nervous system including basal ganglia. Its toxic mechanism is related to oxidative stress, mediated by toxic free radicals but is specultives. In the present study, we have investigated to manifest apoptosis in manganese-induced cytotoxicity in primary neuronal cell culture of rat basal ganglia. METHOD: To detect apoptotic neuronal cells were stained by the terminal deoxynu-cleotide(TdT)-mediated dUTP nick end-labelling(TUNEL) method and apoptotic changes in nuclei of neurons were observed by electron microscopy. RESULTS: We showed that TUNEL immunostain showed brownish signal in the nuclei of apoptotic cells and the proportions of apoptotic cells in Manganese treatment groups were more higher than controls. On transmission electron microscopy, there were chromatine condensation with margination toward nuclear membrane and condensation of cytoplasm in the treated with luM MnC1, for 48 hours in a basal ganglia neurons. Apoptotic bodies were found and consisted of semilunar-like condensed nuclei with relatively intact cytoplasmic organelles. CONCLUSIONS: Apoptosis appears to be one mechanism in the manganese-induced neuronal cell death. Manganese intoxication is a convenient model for apoptosis study.

We report herein a case of primary cutaneous diffuse large B-cell lymphoma with multiple skin lesions in a Korean woman. A 56-year-old woman presented with rapidly growing multiple sub-cutaneous nodules in her right flank and right upper arm. Microscopic examination of skin biopsy specimen showed diffuse infiltrates of large atypical lymphocytes with vesicular nuclei, prominent nucleoli and moderate degree of mitotic figures in deep dermis and subcutis. Immunophenotypic studies revealed the lymphoid infiltrates reacted with CD45, CD20 and bcl-2 protein, but none of the sections expressed CD3, bcl-6 protein and CD30. In physical examination and staging work-up, we could not find any other extracutaneous or systemic involvement. She was treated with 2 cycles of high-dose multiagent chemotherapy with the Vanderbilt and the BEAM regimen combined with the autologous peripheral blood stem cell transplantation. Until now, 10 months after termination of treatment, she has shown improvement of all skin lesions and no development of extracutaneous disease.

PURPOSE: To investigate the clinical manifestations, management, and ophthalmologic complications of orbital roof fractures and zygoma fractures. METHODS: A retrospective survey of 119 patients who visited Korea University Medical Center from June 2009 to June 2010 was performed. The sex, age, causes, fracture characteristics, neurologic injury, ocular injury, and combined facial bone fractures of patients who were diagnosed with orbital roof fracture and zygoma fracture were statistically analyzed. RESULTS: The mean age of patients with orbital roof fracture was 33.0 years old. The most common cause of orbital roof fracture was traffic accident (36.1%) with 6 patients receiveing surgical treatement (9.8%). Among the ophthalmologic diagnoses of the patients with orbital roof fracture, traumatic iridocyclitis was the most common (7 eyes) followed by eyeball rupture (2 eyes). The mean age of patients with zygoma fracture was 36.6 years old. The most common cause of zygoma fracture was traffic accident (32.8%), with 51 patients receiving surgical treatement (87.9%). Among the ophthalmologic diagnoses of the patients with zygoma fracture, traumatic iridocyclitis was the most common (6 eyes), followed by commotio retina (4 eyes). CONCLUSIONS: The present study regarding clinical characteristics and treatment of orbital roof fracture and zygoma fracture is helpful for ophthalmologists regarding the treatment of accompanying ophthalmologic complications.

Radiofrequency ablation (RFA) is a new, minimally invasive modality that serves as an alternative to surgery in patients with thyroid tumors. The Task Force Committee of the Korean Society of Thyroid Radiology developed recommendations for the optimal use of RFA for thyroid tumors in 2012 and revised them in 2017. Herein, we review and summarize the 2017 thyroid RFA guideline and compare it with the 2012 thyroid RFA guideline.

PURPOSE: To clarify the relationship between various factors (sociodemographic factors, health behavioral risk factors and health status, and diabetic factors) related to diabetic retinopathy and to suggest improvements regarding the associated medical examination. METHODS: The subjects were 1,444 diabetic patients diagnosed in the 5th Korean National Health and Nutrition Examination Survey (KNHANES), aged 19 years or older, who underwent non-mydriatic fundus photography. The criteria for diagnosing diabetes were a fasting glucose level ≥ 126 mg/dL and a previous diagnosis of diabetes or currently undergoing treatment. The diagnosis of diabetic retinopathy followed the modified Airlie House classification. Univariate and multivariate analyses of diabetic retinopathy were performed. RESULTS: Among the 1,444 patients who were diagnosed with diabetes, 277 had diabetic retinopathy; the prevalence rate was 19.18%. The higher the body mass index, the lower the risk of diabetic retinopathy by 0.924 times (p = 0.001; 95% confidence interval [CI], 0.883–0.966). The longer the duration of diabetes, the greater the risk of diabetic retinopathy; the prevalence period group of more than 11 years had a 26.025-fold higher risk than the newly diagnosed group (p < 0.001; 95% CI, 10.840–62.482). The risk of diabetic retinopathy increased with the hemoglobin A1c (HbA1c) level; the risk was 5.973-fold higher in the group with HbA1c above 11.0% (p < 0.001; 95% CI, 2.984–11.956) compared with the group with HbA1c < 6.0%. The risk of diabetic retinopathy was 2.050-fold greater with insulin injections (p = 0.003; 95% CI, 1.284–3.275). CONCLUSIONS: The risk of diabetic retinopathy was higher in patients with a longer duration of diabetes, a high HbA1c level, and in those using insulin. These findings highlight the need for early education and ophthalmologic examinations for at-risk patients.

From 1981 to 1993, one hundred and thirty eight patients had been treated by free flap or island flap, for the tissue defects of the extremities. Among these 138 patients, vascularized bone graft was 29 cases, soft tissue free flap 40, replantation 22, local island flap 45, and lymphovenous shunt 2. Average age at the time of operation was 27 years(1-66 years), and men were 110, women 28. Average duration of follow-up was 2 years and 8 months(4 months-11 years and 8 months). Twenty nine cases of vascularized bone graft was consisted of fibular graft in 15 patients, ilium 8, joint transplantation 4, thumb reconstruction using big toe 1, and rib 1. Four of them were failed. Among 40 patients of soft tissue free flap, latissimus dorsi flap was 12 cases, dorsalis pedis flap 11, scapular flap 8, wraparound procedure 7 and gracilis flap 2. Seven of them were failed. The levels of replantations were both lower extremities in one patient, leg 1, arm 2, distal forearm 2, and finger(s) 16. In six patients, replantation was nor successful. Among 45 patients of local island flap, lateral supramalleolar island flap was performed in 8 patients, dorsalis pedis flap 2, Chinese flap 10, reverse ulnar artery flap 4, reverse posterior interosseous artery flap 3, neurovascular island flaps for fingers 14, and others 4. Two of them were failed. Two cases of lymphovenous shunt for the treatment of lymphedema were successful. As a whole, 119 cases were successful(86%) among 138 cases including local island flap 45 cases.

Journal of Retina 2024;9(1):10-17
Purpose:
The purpose of this study is to investigate peripapillary retinal nerve fiber layer (RNFL) and macular retinal layer thickness according to serum homocysteine concentration.
Methods:
Serum homocysteine levels of 120 retinal vein occlusion patients were measured. Peripapillary RNFL thickness and macular retinal layer thickness of unaffected eyes were measured by spectral domain optical coherence tomography and analyzed.
Results:
Average peripapillary RNFL thickness thinning (86.18 ± 19.78 µm vs. 99.61 ± 17.21 µm) (p < 0.001) and all quadrant (superior, nasal inferior, temporal) of peripapillary RNFL thickness thinning were observed in hyperhomocysteinemia patients. Average central macular thickness (CMT) (266.01 ± 29.59 µm vs. 278.71 ± 25.17 µm) was thinner in hyperhomocysteinemia patients (p = 0.029). Thinning of the macular nerve fiber layer (11.71 ± 3.46 µm vs. 14.35 ± 9.03 µm) and inner nuclear layer (25.45 ± 9.84 µm vs. 30.94 ± 13.88 µm) were also observed (p = 0.022, p = 0.041, respectively). There was a negative correlation between serum homocysteine and peripapillary RNFL thickness (r = -0.223, p = 0.015), and CMT (r = -0.230, p = 0.012), especially of the inner retinal layer.
Conclusions
This study found associations of serum homocysteine with peripapillary RNFL and macular retinal layer thickness.

The hypoglossal nerve is a motor supply of the tongue. Hypoglossal nerve palsy after general anesthesia is rare but there have been several reports showing an association with oropharyngeal manipulation such as intubation, bronchoscopy, and laryngeal mask airway. The main mechanism considered has been a temporary compression of the nerve along its superficial course at the lateral root of the tongue during oropharyngeal manipulation. We encountered a patient who complained speaking and swallowing difficulties after general surgery. A deviation to the affected side, atrophy, and fasciculation of tongue were observed. Almost all palsies recovered spontaneously. We present a patient with a transient unilateral hypoglossal nerve palsy after an uncomplicated intubation and anesthesia for surgery for humerus fracture in the beach-chair position.
