PURPOSE: Peritoneal seeding of gastric cancer is known to have a poor prognosis. With the diagnosis of peritoneal seeding, there is no effective treatment modality. Gastrectomy with chemotherapy or primary chemotherapy is basically one of major options for this condition. This study was conducted to compare the clinical outcomes of these treatments and to identify the better way to improve the prognosis of patients with peritoneal seeding. MATERIALS AND METHODS: Between 2001 and 2007, gastric cancer patients with peritoneal seeding by preoperative or intraoperative diagnosis were reviewed retrospectively. The enrolled patients were divided as primary gastrectomy and primary chemotherapy group. Clinicopathologic characteristics and clinical outcomes of groups were analyzed and compared. RESULTS: Fifty-four patients were enrolled. 21 patients belonged to the group of primary gastrectomy and 33 patients were to the primary chemotherapy group. Among 33 patients of the primary chemotherapy group, 17 patients were received only chemotherapy and 16 patients were received gastrectomy due to the good responses of primary chemotherapy. The 3 years survival rates were 14% in primary gastrectomy group, 55% in patients who received gastrectomy after primary chemotherapy, and 0% in patients with primary chemotherapy only. CONCLUSIONS: Although this study had many limitations, some valuable information was produced. In terms of survival benefits for the gastric cancer patients with peritoneal seeding, primary gastrectomy and additional gastrectomy after primary chemotherapy revealed the better clinical outcomes. But, prospective randomized clinical study and multi-center study are should be performed to decide proper treatment for gastric cancer patients with peritoneal seeding.

Thyroid carcinogenesis is accompanied by loss of thyroid-specific functions and refractory to radioiodine and thyroid stimulating hormone (TSH) suppression therapy. Redifferentiating agents have been shown to inhibit tumor growth and improve the response to conventional therapy. Polyphenol phytochemicals (PPs) in fruits and vegetables have been reported to inhibit cancer initiation, promotion, progression and induce redifferentiation in selected types. In this study we examined PPs induce redifferentiation in thyroid cancer cell lines. We investigated the effects of genistein, resveratrol, quercetin, kaempferol, and resorcinol on the F9 embryonal carcinoma cell differentiation model. The thyroid cancer cell lines, TPC-1, FTC-133, NPA, FRO, and ARO, displayed growth inhibition in response to genistein, resveratrol, quercetin. We further demonstrated that genistein decreased the dedifferention marker CD97 in NPA cells and resveratrol decreased CD97 in FTC-133, NPA, FRO cells and quercetin decreased CD97 in all cell lines. We observed increased expression of differentiation marker NIS in FTC-133 cells in response to genistein, and resveratrol but no change in NPA, FRO, ARO cells. Quercetin increased or induced NIS in FTC-133, NPA, FRO cells. These findings suggest that PPs may provide a useful therapeutic intervention in thyroid cancer redifferentiation therapy.

PURPOSE: To evaluate the changes of axial length (AXL) in eyes with unilateral idiopathic central serous chorioretinopathy (CSC) after resolution of serous retinal detachment. METHODS: A total of 31 patients diagnosed with idiopathic unilateral CSC were included in this study. The changes of AXL according to serous retinal detachment were examined. The keratometric value and AXL were measured using partial coherence interferometry. Serous retinal detachment and central macular thickness (CMT) were measured by spectral domain optical coherence tomography. RESULTS: The mean age of the 31 CSC patients, including 19 males, was 42.7 years. The AXL was significantly increased from 23.41 to 23.58 mm after resolution of serous retinal detachment (p < 0.001). The CMT was significantly decreased from 413.4 to 226.8 µm after resolution of serous retinal detachment (p < 0.001). The differences in AXL correlated with CMT differences and subretinal fluid height (r = −0.616, p < 0.001 and r = −0.637, p < 0.001, respectively), and the best-corrected visual acuity was significantly different after resolution of serous retinal detachment (p < 0.001). CONCLUSIONS: In unilateral idiopathic CSC with serous retinal detachment, a shortened AXL in the acute phase was restored after resolution of serous retinal detachment.

Background: Baseball players are subjected to repeated loads on the supraspinatus and long head biceps tendon from youth, and repetitive pitching motions can cause shoulder injuries. The purpose of this study was to evaluate the immediate changes caused by pitching in the supraspinatus muscle-tendon, long head of the bicep tendon (LHBT), and shoulder range of motion (ROM) and to verify their recovery over time in youth baseball players. Methods: Fifteen youth baseball players (mean age, 11.5 ± 1.3 years) were enrolled. The thicknesses of the supraspinatus tendon and LHBT and the strain ratios (SRs) of supraspinatus muscle and tendon were measured by sonoelastography. ROMs of shoulder joints (abduction, external rotation at 90° of abduction [ABER], and internal rotations at 90° of abduction [ABIR]) and horizontal adduction (HA) were measured using a goniometer. All measurements were performed on the throwing shoulders before and immediately after pitching (mean pitch count, 78.3 ± 13.3) and at 30 minutes, 24 hours, and 72 hours after pitching. Results: The thickness of supraspinatus tendon (6.64–6.27 mm, p = 0.026) and that of LHBT (2.56–2.26 mm, p = 0.021) significantly decreased immediately after pitching. The SRs of supraspinatus muscle tended to decrease, whereas SRs of supraspinatus tendon tended to increase immediately after pitching. ABER increased (119.7°–127.3°, p = 0.001) and HA decreased (34.7°–29.3°, p = 0.023) immediately after pitching. All immediate changes recovered 72 hours after pitching. Conclusions The immediate effects of pitching on the supraspinatus muscle-tendon, LHBT, and shoulder ROM in youth baseball players were confirmed in the current study. These changes were recovered to pre-pitch levels 72 hours after pitching. Therefore, we recommend that youth baseball players should rest for three days after pitching to minimize the risk of shoulder injury.

Purpose: We report a case of sympathetic ophthalmia in which the inciting eye was treated with a tectonic keratoplasty using acellular preserved human cornea.Case summary: A 68-year-old man whose left eye was injured by a nail visited our institute complaining of a recent decrease in bilateral vision. The best corrected visual acuity was 0.32 for the right eye and 0.16 for the left. On slit-lamp examination, a superior peripheral corneal perforation with no wound leakage due to iris plugging was seen in the left eye (i.e., the inciting eye). The right eye (i.e., the sympathizing eye) had mutton-fat keratic precipitates and copious fibrinoid strands in the anterior chamber. Bilateral exudative retinal detachment with choroidal folds was prominent in both eyes. The next day, the necrotic iris lump was removed from the inciting eye and adhesiolysis of the iris and tectonic keratoplasty using acellular preserved human cornea were performed. Systemic steroid was started immediately postoperatively. The exudative retinal detachment improved in both eyes and cataract surgery was undertaken for the inciting eye 4 months later. Twenty-one months after the initial visit, the uncorrected visual acuity was 1.0 in the inciting eye, and both eyes had a sunset glow fundus appearance, without optic atrophy or recurrent chorioretinitis. Conclusions Tectonic keratoplasty using acellular preserved human cornea with anti-inflammatory treatment may be a favorable therapeutic option for the inciting eye with peripheral corneal perforation in sympathetic ophthalmia.

Purpose: We report the clinical outcomes of retinal capillary hemangioma (RCH) after the application of various treatments. Methods: We performed a retrospective chart analysis of eight eyes treated for RCH between August 2009 and January 2018. During the follow-up period, the status and progression of the RCHs were checked by fundus photography, fluorescein angiography, and optical coherence tomography, and additional treatments were applied when necessary. Results: Three of the five patients had bilateral RCH, and two had unilateral RCH. Six eyes received laser photocoagulation; two eyes received cryotherapy, and one eye received intravitreal Avastin injection. Three eyes each had intravitreal triamcinolone injection, subtenon triamcinolone injection, and intravitreal dexamethasone injection to control inflammation. Also, two patients took oral prednisolone, and one patient used prednisolone eye drops to control inflammation. Two eyes underwent vitrectomy and scleral buckling due to deterioration of the epiretinal membrane and vitreal traction, respectively. As a result of those treatments, the tumors were stable in five of the eight eyes. However, one eye is now in a pre-phthisis state, and one patient who refused treatment showed progression of the tumor, epiretinal membrane, and traction. Conclusions Because RCHs vary in size, the degree of inflammation, and symptoms, this disorder should be actively treated on a case-by-case basis. Fluorescein angiography should be used periodically to determine recurrence of the tumor or inflammation, and the appropriate treatment should be repeated as necessary. Moreover, regular systemic screening tests for von Hippel-Lindau disease should be performed in RCH patients to ensure that they have no abnormalities other than in the eye.

Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterized by the calcification and ossification of soft tissue, and can lead to severe cervical kyphosis, presenting with a spectrum of physical complaints including dysphagia, hoarseness, stridor, aspiration pneumonia, and dyspnea due to airway compromise. Restrictive ventilatory impairment is very rare. We encountered a 73-year-old man with DISH presenting with progressive dysphagia and dyspnea over a few months. The symptoms were evaluated with a video fluoroscopy swallowing study and pulmonary function tests (PFT). The PFT revealed restrictive ventilatory impairment. A neck magnetic resonance imaging (MRI) study showed anterior cervical osteophytes causing upper airway compromise and compression of the esophagus. Osteophytes were removed surgically and the patient improved clinically. Here, we describe the case with a literature review.

PURPOSE: There is a continuing debate about whether small bowel obstruction (SBO) is best managed operatively or nonoperatively. There is also no definite criteria for physician to decide to operate patient with SBO. This retrospective study was designed to determine the factors influencing the treatment modality of SBO. METHODS: A clinical analysis was applied to 95 patients with SBO who were admitted to the emergency department of Seoul National University Hospital from January, 2000 to December, 2001. The patients were divided into the operative and non-operative treatment groups according to the treatment modality. We compared parameters such as age, sex, the etiology of SBO, the history of previous SBO, the history of previous operation due to SBO, time period from onset of symptoms to admission, and symptoms and signs between two groups. RESULTS: Among 95 cases, the operative management was performed in 21 cases and the non-operative treatment in 74 cases. There was no significant difference in the distribution of age and sex between two groups. The most common etiology of SBO was adhesion due to previous operation. In the operative treatment group, 12 (57.1%) cases had the history of previous operation because of SBO, which showed a significant difference compared to the non-operative treatment group (p<0.001). The major symptoms and signs were abdominal pain, vomiting, abdominal tenderness, hyperperistalsis, leukocytosis, tachycardia, rebound tenderness and fever. Of these symptoms and signs, rebound tenderness was only more common in the operative group than in the non-operative group (p<0.001). CONCLUSION: At the time of admission to the emergency department, the rebound tenderness in patients with SBO is an important factor to consider the early operative intervention.
