Purpose: We aimed to investigate manifestations and patterns of care for patients with brain metastasis (BM) from breast cancer (BC) and compared their overall survival (OS) from 2005 through 2014 in Korea. Materials and Methods: We retrospectively reviewed 600 BC patients with BM diagnosed between 2005 and 2014. The median follow-up duration was 12.5 months. We categorized the patients into three groups according to the year when BM was initially diagnosed (group I [2005-2008], 98 patients; group II [2009-2011], 200 patients; and group III [2012-2014], 302 patients). Results: Over time, the median age at BM diagnosis increased by 2.2 years (group I, 49.0 years; group II, 48.3 years; and group III, 51.2 years; p=0.008). The percentage of patients with extracranial metastasis was 73.5%, 83.5%, and 86.4% for group I, II, and III, respectively (p=0.011). The time interval between BC and BM was prolonged in patients with stage III primary BC (median, 2.4 to 3 years; p=0.029). As an initial brain-directed treatment, whole-brain radiotherapy alone decreased from 80.0% in 2005 to 41.1% in 2014. Meanwhile, stereotactic radiosurgery or fractionated stereotactic radiotherapy alone increased from 13.3% to 34.7% during the same period (p=0.005). The median OS for group I, II, and III was 15.6, 17.9, and 15.0 months, respectively, with no statistical significance. Conclusion The manifestations of BM from BC and the pattern of care have changed from 2005 to 2014 in Korea. However, the OS has remained relatively unchanged over the 10 years.

BACKGROUND: Heatstroke is one of the most serious heat-related illnesses. However, establishing public policies to prevent heatstroke remains a challenge. This study aimed to investigate the most relevant climate elements and their warning criteria to prevent outdoor heatstroke (OHS).METHODS: We investigated heatstroke patients from five major hospitals in Daegu metropolitan city, Korea, from June 1 to August 31, 2011 to 2016. We also collected the corresponding regional climate data from Korea Meteorological Administration. We analyzed the relationship between the climate elements and OHS occurrence by logistic regression.RESULTS: Of 70 patients who had heatstroke, 45 (64.3%) experienced it while outdoors. Considering all climate elements, only mean heat index (MHI) was related with OHS occurrence (p=0.019). Therefore, the higher the MHI, the higher the risk for OHS (adjusted odds ratio, 1.824; 95% confidence interval, 1.102–3.017). The most suitable cutoff point for MHI by Youden’s index was 30.0°C (sensitivity, 77.4%; specificity, 73.7%).CONCLUSION: Among the climate elements, MHI was significantly associated with OHS occurrence. The optimal MHI cutoff point for OHS prevention was 30.0°C.

OBJECTIVETo investigate the anti-oxidative stress and preventive effect of modified Gongjin-dan (WSY-1075) in a detrusor underactivity rat model.

METHODSRats were randomly allocated to three groups: shamoperated (control), bladder outlet obstruction-induced detrusor underactivity (BOO-DU), and BOO-DU with WSY-1075 (WSY) groups. WSY-1075 was orally administrated to rats 200 mg daily for 2 weeks prior to the operation and 4 weeks after the operation. Bladder outlet obstruction was surgically induced in rats by ligation around the urethra avoiding total obstruction. Cystometrography was conducted on rats in each group for examination of bladders.

RESULTSCompared with the control group, bladder outlet obstruction led to a significant increase in oxidative stress with consequent changes to molecular composition, and decrease in maximal detrusor pressure (P<0.05). WSY-1075 treatment significantly suppressed oxidative stress and prevented degenerative and dysfunctional changes in bladder, as compared with BOO-DU group (P<0.05).

CONCLUSIONWSY-1075 had beneficial effect on prevention of BOO-DU.

BACKGROUND/OBJECTIVES: This study was performed to measure fat-soluble vitamins and minerals in breast milk of Korean lactating mothers who exclusively breastfed their babies. SUBJECTS/METHODS: Breast milk samples were collected from 334 mothers. Concentrations of retinol and α-tocopherol were analyzed by high performance liquid chromatography ultraviolet spectrometry while concentrations of minerals were measured by inductively coupled plasma optical emission spectrometry. RESULTS: Retinol and α-tocopherol contents of breast milk were 39.58 ± 19.64 µg/dL and 0.23 ± 0.13 mg/dL, respectively. Average sodium, potassium, calcium, phosphorus, and magnesium levels in breast milk were 11.11 ± 5.16, 38.56 ± 9.01, 27.87 ± 6.10, 13.56 ± 3.30, and 3.05 ± 0.65 mg/dL, respectively. Contents of trace elements such as iron, zinc, copper, and manganese were 40.26 ± 46.21, 98.40 ± 62.47, 24.09 ± 9.03, and 0.90 ± 1.63 µg/dL, respectively. Fat-soluble vitamin concentration was positively correlated with total fat in milk samples, but no significant differences were observed in levels of retinol, α-tocopherol, or minerals based on whether or not lactating women were taking dietary supplements. CONCLUSIONS: Micronutrient contents of breast milk samples from Korean lactating women were comparable to those of other nations. Retinol and α-tocopherol levels were correlated and also with total fat in breast milk.

Seborrheic dermatitis is a chronic recurrent inflammatory disorder presumed to be caused by increased sebaceous gland secretion, metabolic changes in the cutaneous microflora, and changes in the host immune function. Stellate ganglion block (SGB) is known to increase the blood flow rate without altering the blood pressure, heart rate, or cardiac output, to stabilize hypertonic conditions of the sympathetic nerves, and to affect the endocrine and immune systems. It is used in the differential diagnosis and treatment of autonomic nervous system disorders of the head, neck, and upper limbs. The authors report the first case of successful treatment of a patient with seborrheic dermatitis through repeated SGB trials.

OBJECTIVES: To clarify the anatomical distribution of the lingual artery in normal adult subjects through histopathologic evaluations. METHODS: Eighteen healthy cadaveric tongues were used to produce 8 paraffin-embedded tissue sections each. Length from midline raphe, depth from dorsum of tongue and the whole transverse length tongue were measured. The lateral distance, depth, and proportion of lateral distance of deep lingual artery were determined from tip to base of tongue gradually. Lateral distance is length from median raphe to the center of deep lingual artery lumen. Depth is vertical distance from dorsal surface of tongue to the center of deep lingual artery. Proportion of lateral distance is obtained by dividing lateral distance with transverse length from median raphe to lateral border of tongue. The degree of symmetry between right and left sides and the difference between selected spots were evaluated. RESULTS: Right and left sides of the lingual artery were symmetric. The lingual artery was lateralized as it run posterior. The lingual artery runs gradually deeper from the surface as it goes near the base of tongue. Both length and depth of the lingual artery gradually increased between 0%–75% of the mobile tongue, but 75%–100% zone of the lingual artery showed no significant difference. There was no anastomosis between right and left side of the lingual arteries. The lingual artery was located within 50% of the transverse length of tongue from median raphe. CONCLUSION: The present study reveals 3-dimensional information on the anatomical distributions of the lingual artery in normal adult subjects. These findings gives us beneficial information about the handling of the lingual artery during oral and base of tongue-related surgery.

BACKGROUND: Limited information is available regarding dermatoscopic differences between non-aggressive and aggressive types of basal cell carcinoma (BCC). OBJECTIVE: To investigate dermatoscopic differences between non-aggressive and aggressive types. METHODS: We evaluated 145 histopathologically confirmed BCCs from 141 patients. Histopathologic types and aggressiveness from 4 mm punch biopsy and their dermatoscopic findings were evaluated. We assessed the statistical significance of dermatoscopic differences between non-aggressive and aggressive types. To objectively predict aggressiveness, we created a "dermatoscopic index of BCC aggressiveness" in which 1 point was added and subtracted for each dermatoscopic finding significantly higher in aggressive and non-aggressive types, respectively. RESULTS: Large blue-gray ovoid nests were found more frequently in non-aggressive type than aggressive one (85/105 [80.9%] vs. 21/40 [52.5%], p=0.001). Compared to non-aggressive type, aggressive type had more multiple blue-gray globules (29/40 [72.5%] vs. 57/105 [54.3%], p=0.046), arborizing telangiectasia (29/40 [72.5%] vs. 48/105 [45.7%], p=0.004), and concentric structure (11/40 [27.5%] vs. 12/105 [11.4%], p=0.018). Regarding dermatoscopic index, cases of aggressive type with a score of 1 were most common (n=18, 45.0%), followed by a score of 2 (n=14, 35.0%). Limited number of aggressive type of BCCs and the effect of width on the determination of histopathologic aggressiveness. CONCLUSION: Aggressive type BCCs more often exhibited multiple blue-gray globules, arborizing telangiectasia, and concentric structure, while the non-aggressive type exhibited large blue-gray ovoid nests more frequently. Score exceeding 2 on the dermoscopic index can be screening criteria for aggressiveness. These dermatoscopic features and dermoscopic index could be useful for assessing aggressiveness of BCCs before surgery.

BACKGROUND: Despite efforts to treat trachyonychia, there is no promising treatment modality. OBJECTIVE: This study evaluated the efficacy and safety of calcipotriol plus betamethasone dipropionate ointment on trachyonychia. METHODS: A total of 39 patients with 432 nails affected by trachyonychia were enrolled. All patients applied calcipotriol/betamethasone ointment once daily without occlusion for 6 months. Outcome measures were assessed by physician's global assessment (degree of roughness: 0, clear; 1, mild; 2, moderate; 3, marked; 4, severe) at all time points. RESULTS: After 6 months of therapy, 98.6% (426/432) of nails showed significant clinical improvement; 4.2% were completely free from nail lesions. The mean physician global assessment score decreased significantly from 3.5 to 1.7 points (p< 0.05). No serious side effects were reported, except mild pruritus and erythema in 2 patients. CONCLUSION: This is the first study to prospectively evaluate the efficacy and safety of calcipotriol/betamethasone ointment for the treatment of trachyonychia. The results indicate topical calcipotriol/betamethasone is an effective and safe treatment for symptom improvement of trachyonychia.

Patients treated with peritoneal dialysis have increased intra-abdominal pressure and a high prevalence of abdominal wall complications. Hernias can lead to significant morbidity in patients on peritoneal dialysis. Hernias are clinically important because of the risk of incarceration, strangulation and subsequent bowel obstruction, rupture, and peritonitis. In this paper, a case of incarcerated umbilical hernia with small bowel obstruction in a continuous ambulatory peritoneal dialysis (CAPD) patient is reported. The small bowel obstruction improved after herniorrhaphy, and the peritoneal dialysis was resumed 2 weeks after the herniorrhaphy. The patient had been undergoing CAPD without technical failure until the 2 months follow-up after the herniorrhaphy. This case shows that early detection of incarcerated umbilical hernia and herniorrhaphy can prevent resection of a strangulated small bowel so that it can remain on CAPD without post-operative technical failure. Umbilical hernias should be carefully observed and intestinal obstruction should be considered when a CAPD patient with an umbilical hernia has abdominal pain.
