Synlabia after Severe Monilia Infections: A Case Report

Case. A 25-year-old woman presented with acute urine retention with overflow 6 months after an inadequate treatment of severe monilia infections. Examination revealed complete adhesion between both labia majora. Division of adhesion was done with reconstruction by labial mucocutaneous flap. Complete recovery was achieved with good cosmetic outcome. Conclusion. Labial adhesions whatever their severity is can be surgically divided with complete correction by locally designed flap to reconstruct the introuitus with rapid recovery, good healing, and good cosmetic outcome

Long-term exposure to xenoestrogens alters some brain monoamines and both serum thyroid hormones and cortisol levels in adult male rats

AbstractThe present study was designed to examine the effect of long-term treatment with the phytoestrogen soy isoflavone [(SIF); 43mg/kg body weight/day] and/or the plastics component bisphenol-A [(BPA); 3mg/kg body weight/day] on some monoamines in the forebrain and both serum thyroid hormones and cortisol levels of adult rats. Significant increases in serotonin (5-HT) and norepinephrine (NE) level, and significant decreases in 5-hydroxyindoleacetic acid (5-HIAA) level and 5-HIAA/5-HT ratio, were observed after treatment with SIF or BPA. Level of dopamine (DA) was increased in SIF-treated group and decreased in BPA-treated group. Activity of monoamine oxidase (MAO) was decreased in all treated groups. The level of serum thyroid hormones (fT3 and fT4) was increased after treatment with SIF and decreased after exposure to BPA, while cortisol level was increased in all treated groups. It may be concluded that long-term exposure to SIF or BPA disrupts monoamine levels in the forebrain of adult rats through alteration in the metabolic pathways of amines and disorders of thyroid hormones and cortisol levels

Consumers' valuation of two packaging aspects for fresh lamb meat: Vacuum and information labels

The use of vacuum packaging for fresh meat with low rate of turnover in the supermarket shelves, as it is the case of lamb meat in Spain, is recommended. Because the amount of mandatory information on fresh-meat labels has increased, there is a need to design new labels to enhance the support for this information. Therefore, to anticipate the consumer''s acceptance of vacuum packaging and the preferences for newly designed labels is of vital importance. This is the objective of the paper; in particular, it measures the consumers'' relative importance of the vacuum packaging and different labels in relation to other important lamb-meat characteristics (type of cut, price, and regional indication). To do that, a choice experiment was used and an error-component random-parameter model with correlated errors was estimated. Results suggest that consumers positively value all of the attributes except for the new designed labels. In particular, consumers positively value the vacuum packaging but to lesser extent than other lamb-meat attributes such as the type of cut, the protected geographical indication certification, and the price. However, consumers only value the vacuum packaging in the case of fresh lamb meat with a protected geographical indication certification. Moreover, this valuation is higher for older consumers who use, to a higher extent, their own direct appraisal of the meat and the information on the label when shopping and give less importance to the presence of liquid around the meat

Modified Koyanagi Technique in Management of Proximal Hypospadias

Background/Purpose: One stage urethroplasty with parameatal foreskin flap (OUPF) applicable to all types of hypospadias was first described by Tomohiko Koyanagi, however high complication rates were reported.The aim of this study is to analyze the results of a modification of the Koyanagi technique as a one-stage repair of proximal hypospadias. Patients and Methods: During the period of from March 2008 to March 2009, 30 patients underwent treatment of proximal hypospadias using the modified Koyanagi technique. Patient age at the time of surgery ranged from 6 to 24 months. In all cases, the urethral opening was at or just proximal to the penoscrotal junction. Follow up ranged from 3 months to 1 year. Results: Primary success occurred in 27 cases (90%) with accepted cosmetic appearance. Complications occurred in 3 cases (10%). Urethrocutaneous fistula occurred in 2 cases (6.7%). Meatal recession occurred in 1 case (3.3%). There was no incidence of meatal stenosis, urethral stricture, residual chordee or complete flap necrosis. Conclusion: The modified technique permits one-stage repair of proximal hypospadias with low complication rates. Keywords: Hypospadias, Koyanagi, One stage urethroplasty

Near-total pancreatectomy for persistent hyperinsulinemic hypoglycemia of infancy (nesidioblastosis): Mansoura experience

Background/purpose Persistent hyperinsulinemic hypoglycemia of infancy (PHHI) is the most common cause of persistent hypoglycemia in infancy with consequences such as seizures and brain damage. Treatment that prevents the occurrence of these sequele is essential. When medical therapy fails or complications are anticipated, early pancreatectomy is recommended to maintain euglycemia. The aim of this study was short-term evaluation of near-total pancreatectomy for PHHI after failure of medical treatment in patients in Mansoura, Egypt.Patients and methods During May 2002 to May 2010, 33 patients suffering from persistent hyperinsulinemic hypoglycemia were admitted to Mansoura university child hospital. Twenty patients responded to medical treatment and 13 patients (eight girls and five boys) were treated by near-total (90–95%) pancreatectomy after failure of medical treatment. Their ages at the time of surgery ranged from 20 days to 27 months. Only patients who were surgically managed were included in this study. All of them suffered from symptoms of PHHI: thermoregulatory problems in five cases, tremors in five cases, seizures in three, irritability in five, respiratory distress in eight, apnea in four, hypotonia in four, lethargy in five, and feeding difficulty in four cases. All cases were diagnosed following strict criteria that included bouts of hypoglycemia without acidosis coinciding with increased insulin level. Follow-up ranged from 3 months to 8 years.Results Primary success occurred in two cases (15%); four more cases (31%) developed temporary diabetes mellitus, and one case (8%) had a temporary pancreatic fistula. Eventually, total cure occurred in seven cases (54%); six cases (46%) developed a variety of complications; and persistent hypoglycemia was seen in two. Persistent diabetes mellitus was observed in three patients, developmental delay in one, and persistent neurological deficit in two patients; there was one case of mortality.Conclusion Near-total (90–95%) pancreatectomy is a suitable procedure for treatment of nesidioblastosis not responding to medical treatment and should be performed as early as possible. Keywords: Mansoura, near-total pancreatectomy, persistent hyperinsulinemic hypoglycemi

Minimal-memory realization of pearl-necklace encoders of general quantum convolutional codes

Quantum convolutional codes, like their classical counterparts, promise to offer higher error correction performance than block codes of equivalent encoding complexity, and are expected to find important applications in reliable quantum communication where a continuous stream of qubits is transmitted. Grassl and Roetteler devised an algorithm to encode a quantum convolutional code with a "pearl-necklace encoder." Despite their theoretical significance as a neat way of representing quantum convolutional codes, they are not well-suited to practical realization. In fact, there is no straightforward way to implement any given pearl-necklace structure. This paper closes the gap between theoretical representation and practical implementation. In our previous work, we presented an efficient algorithm for finding a minimal-memory realization of a pearl-necklace encoder for Calderbank-Shor-Steane (CSS) convolutional codes. This work extends our previous work and presents an algorithm for turning a pearl-necklace encoder for a general (non-CSS) quantum convolutional code into a realizable quantum convolutional encoder. We show that a minimal-memory realization depends on the commutativity relations between the gate strings in the pearl-necklace encoder. We find a realization by means of a weighted graph which details the non-commutative paths through the pearl-necklace. The weight of the longest path in this graph is equal to the minimal amount of memory needed to implement the encoder. The algorithm has a polynomial-time complexity in the number of gate strings in the pearl-necklace encoder.Comment: 16 pages, 5 figures; extends paper arXiv:1004.5179v

Effect of NaCl Salinity on Growth and Mineral Composition of Ziziphus spina-christi (L.) Willd.

Ziziphus spina-christi (L.) Willd. is a fruit tree species growing wild in arid and semi-arid areas of Asia and Africa where rural populations intensively use its fruits, leaves, bark and wood. However, little is known about the effects of salinity, a widespread problem in these regions, on early growth and mineral composition of this species. This study was conducted under controlled conditions to contribute to filling this gap. Six weeks old seedlings of Z. spina-christi germinated in a full strength Hoagland solution were subjected to 0, 40, 80 and 160 mM NaCl. Compared to the unstressed control salinity levels of 80 and 160 mM reduced plant height, leaf number, leaf chlorophyll, total leaf area and dry matter by 50%. Salinity levels of 40, 80 and 160 mM enhanced leaf water contents by 14, 16 and 17%, respectively and 160 mM NaCl raised the concentration of Na and Cl ions in leaf tissues 81- and 21-fold. The K/Na ratio, in contrast, was hardly affected by increasing salinity indicating adaptation or tolerance of Z. spina-christi to low or moderate NaCl salinity. These results suggest that Z. spina-christi could be an interesting species for re-vegetation of moderately degraded saline lands
