Congenital hypertrophic pyloric stenosis is the most common intra-abdominal disease required surgery during the first few months of life. The expression of pyloric stenosis is dependent upon the genetic influence of ancestors affected with the disease, as well as unknown environmental influences in the postnatal period. Pyloric stenosis has been reported in multiple sibs in a family, which suggests the genetic influence on the expression of this disease. Until now, the genetic influence is thought a sex-modified polygenic or multifactorial background which facilitates the expression of a common dominant gene. We experienced a case of congenital hypertrophic pyloric stenosis in a two siblings. The siblings suffered projectile vomiting for 2~4 days at 16 days old of age and 15 days old of age. After we confirmed the diagnosis by upper gastrointestinal series and abdominal sonogram, the Fredet-Ramstedt pyloromyotomy was done successfully. This case suggests the genetic influence on the expression of this disease.

The subepidermal calcified nodule, also known as a form of calcinosis cutis, is characterized by solitary circumscribed deposits of insoluble calcium within the subepidermis. The disease is not associated with any systemic or cutaneous diseases, or any biochemical abnormalities. The pathogenesis is still unknown. A 55-year-old female presented with a 4-month history of solitary skin-colored, hyperkeratotic papule on the left upper eyelid. The lesion was asymptomatic and had increased slowly in size. It is interesting that excisional biopsy showed typical histopathologic features of the subepidermal calcified nodule and the clear cell syringoma.

This study was aimed to investigate management conditions and dietitians' perception for improvement of school milk programs. Using an online sampling method, collected data from 1,723 dietitians nationwide were analyzed. The results show that 44.4% of respondents carried out the cyclic school milk program, providing various types of dairy products either weekly or monthly. Further, 80.3% of respondents answered that preference survey results were a determining factor in their choice of school milk provider, and 55.9% said that a school steering committee made the decision on relevant facts of the school milk program. For diversification of school milk type, 60.5% of respondents wanted to maintain the current system, and 39.5% answered that milk type needed to be diversified. The respondents preferred fermented milk products, functional milk, and processed milk, in order, if school milk type is diversified. To improve perception and knowledge about milk, 66.0% of respondents thought that nutrition education by a nutrition teacher would be the most effective, and parent's letters or a nutrition newsletter would be helpful. More than half of respondents (55.0%) disagreed with a merged program for school foodservice and milk.

To investigate the properties of ryanodine binding sites of the bird skeletal SR vesicles, SDS PAGE, purification of RyR, and (3H)ryanodine binding study were carried out in the SR vesicles prepared from the chicken pectoral muscle. The chicken SR vesicles have two high molecular weight (HMW) protein bands as in eel SR vesicles on SDS PAGE. The HMW bands on SDS PAGE were found in the (3H) ryanodine peak fraction (Fr3-5) obtained from the purification step of the ryanodine receptor protein. Bmax and KD of the chicken (3H)ryanodine binding sites were 12.52 pmol/mg protein and 14.53 nM, respectively. Specific (3H)ryanodine binding was almost maximal at 50~100 micrometer Ca2+, but was not increased by 5 mM AMP and not inhibited by high Ca2+. Binding was significantly inhibited by 20~100 micrometer ruthenium red and 1 mM tetracaine, but slightly inhibited by Mg2+. From the above results, it is suggested that chicken SR vesicles have the ryanodine binding sites to which the binding of ryanodine is almost maximal at 50~10 micrometer Ca2+, is significantly inhibited by ruthenium red and tetracaine, slightly inhibited by Mg2+, but not affected by AMP and not inhibited by high Ca2+.

BACKGROUND: Necrotizing fasciitis is a life-threatening infectious disease with rapidly progressive involvement of the affected site. Because of the high mortality rate of this disease, early diagnosis, surgical exploration, and administration of appropriate antibiotics are necessary. The present study aimed to further review the changes in the clinical and microbiological characteristics of necrotizing fasciitis using patients' medical records from consecutive databases of 3 hospitals in Korea. MATERIALS AND METHODS: In this study, we retrospectively reviewed the medical records of patients with necrotizing fasciitis who were clinically diagnosed between May 2001 and February 2012 in 3 university hospitals in Korea. In total, the data of 83 patients were analyzed, including those of 20 patients from our previous study in 2006. An organism found in a blood culture or surgical specimen was regarded as a causative organism. RESULTS: Of the 83 patients, 68(81.9%) had community-acquired infections. Ninety microorganism species were indentifed by culture. Streptococcus was the most commonly identified pathogen. Non-fermentative gram-negative bacteria and Candida species have recently emerged, especially in immunocompromised hosts. CONCLUSIONS: Gram-positive organisms are still the most common pathogens of necrotizing fasciitis. However in our study, various gram-negative bacteria with different levels of susceptibility to antibiotics, as well as Candida species, were responsible for the necrotizing fasciitis. Initial empirical antimicrobial agents for necrotizing fasciitis should be considered depending on the individual patient's condition.

Objectives:
. The supine sleep position and the rapid eye movement (REM) stage are widely recognized to exacerbate the severity of obstructive sleep apnea (OSA). Position-dependent OSA is generally characterized by an apnea-hypopnea index (AHI) that is at least twice as high in the supine position compared to other sleep positions. However, this condition can be misdiagnosed if a particular sleep stage—REM or non-REM (NREM)—predominates in a specific position. We explored the impact of the sleep stage on positional dependency in OSA.
Methods:
. Polysomnographic data were retrospectively analyzed from 111 patients with OSA aged 18 years or older, all of whom had an AHI exceeding five events per hour and slept in both supine and non-supine positions for at least 5% of the total sleep time. The overall ratio of non-supine AHI to supine AHI (NS/S-AHI ratio) was compared between total, REM, and NREM sleep. Additionally, a weighted NS/S-AHI ratio, reflecting the proportion of time spent in each sleep stage, was calculated and compared to the original ratio.
Results:
. The mean NS/S-AHI ratio was consistent between the entire sleep period and the specific sleep stages. However, the NS/S-AHI ratios for individual patients displayed poor agreement between total sleep and the specific stages. Additionally, the weighted NS/S-AHI ratio displayed poor agreement with the original NS/S-AHI ratio, primarily due to discrepancies in patients with mild to moderate OSA.
Conclusion
. The weighted NS/S-AHI ratio may help precisely assess positional dependency.
