Summary Background: Systemic isotretinoin has been known for decades to be effective in the treatment of severe forms of rosacea, but it must be used off‐label because of the lack of evidence‐based data. Patients and Methods: 573 patients with rosacea subtype II and III received one of three different dosages of isotretinoin (0.1 mg, 0.3 mg, or 0.5 mg per kg body weight), doxycycline (100 mg daily for 14 days, then 50 mg daily) or placebo in a double‐blinded, randomized way for 12 weeks in 35 German centers. Results: Isotretinoin 0.3 mg/kg proved to be the most effective dose with significant superiority versus placebo. Isotretinoin 0.3 mg/kg showed also significant non‐inferiority versus doxycycline with reduction of lesions of 90 % compared to 83 % with doxycycline. Investigators diagnosed complete remission in 24 % and marked improvement in further 57 % of patients with isotretinoin treatment, in contrast to remission in 14 % and marked improvement in 55 % of patients treated with doxycycline. Isotretinoin 0.3 mg/kg revealed a similar safety profile as for the treatment of acne. Isotretinoin 0.5 mg/kg showed more dermatitis facialis as compared to 0.3 mg/kg. Conclusions: Isotretinoin 0.3 mg/kg is an effective and well‐tolerated therapy option for the treatment of rosacea subtype II and III and can therefore be used successfully as an alternative to therapy with oral antibiotics.

Published: September 2010

SummarySarcoidosis is a granulomatous disease of unknown etiology, which may affect multiple organ systems. The skin is involved in up to one‐third of cases. The development of granulomatous lesions within tattoos is a well‐recognized phenomenon in patients with sarcoidosis. The characteristic histology shows non‐caseating granulomas; however similar findings may be seen in foreign body granulomas. We report on a patient, who developed sarcoidal granulomas within the black pigment of his tattoos. This subsequently led to the diagnosis of pulmonary sarcoidosis.
Phototherapy and photochemotherapy
Authors: Iordanou Eleni , Berneburg Mark 
Published: September 2010

SummaryThe treatment of skin diseases with ultraviolet radiation represents an important therapeutic modality in clinical dermatology, and the number of skin diseases that improve under the phototherapeutic modalities of today is still growing. While clinical phototherapy was originally based on empirical observations, our present understanding of the underlying mechanisms has improved substantially due to important progress in photobiological science. The better understanding of this scientific basis of treatment allows to both choose the correct phototherapeutic modality and determine the most effective treatment regimen. The aim of this article is to discuss the appropriate indications for phototherapy as well as its safe and effective employment, providing practical help in daily clinical phototherapeutic practice.

Authors: Zhang Xiaolei , Naert Ignace , Van Schoonhoven Dorien , Duyck Joke 
Published: September 2010

ABSTRACTObjective: This study aimed to evaluate the effect of direct high‐frequency mechanical stimulation on the peri‐implant tissue healing.Materials and Methods: A total of 48 custom‐made 2‐mm diameter titanium implants were inserted in the tibial epiphyses of 12 rabbits. Half of the implants were stimulated by direct vibration (60 ± 10 Hz) immediately after insertion for 1 and 4 weeks, respectively. The other half served as controls. The samples were collected after the animals were sacrificed and were histologically processed into paraffin sections and stained with haematoxylin and eosin. The bone fraction was measured in an area of 50 and 400 µm around the implant. To rate significant differences a one‐way analysis of variance was used with α set at 5%.Results: No significant difference in bone fraction was found between test and control groups. When the bone fractions of the 50 and 400 µm peri‐implant regions were compared, a significantly larger bone fraction was found in the 50 µm peri‐implant region for the 4‐week stimulated group.Conclusion: Histomorphometric analyses could not reveal a pronounced effect of direct immediate high‐frequency implant loading.

Authors: Degidi Marco , Daprile Giuseppe , Piattelli Adriano 
Published: September 2010

ABSTRACTObjectives: The aims of the present study are to evaluate the primary stability of a sample of 4,135 implants and to investigate the correlations between primary stability and mechanical characteristic of the implant and bone density at insertion time.Material and Methods: The study was conducted from March 2002 to January 2009 at a private practice in Bologna (Italy). Patients were eligible for the study if they needed the insertion of single or multiple implants. Bone density, length, and diameter of each implant were recorded. During surgery for each implant, peak insertion torque (IT) was recorded; the resonance frequency analysis (RFA) values were also collected. Finally, it was recorded whether an implant was lost or removed at an early stage (within 6 months from insertion surgery).Results: A total of 1,045 consecutive patients were included in the study. A total of 4,135 of implants were inserted. The sample presented 1,184 implants inserted in a postextractive site. The mean peak IT was 34.82 ± 19.36. The mean RFA was 71.57 ± 10.63 implant stability quotient. Spearman correlation analysis shows the presence of a weak positive correlation between IT and RFA. The statistical analysis shows a relevant dependency between IT and bone quality and a very weak dependency between RFA and bone quality. Again, the statistical analysis shows a quite weak correlation between length or diameter and IT, but it shows a relevant correlation between length and RFA. Postextractive implants presented a higher mean IT and a lower RFA compared with implants inserted in healed sites. Twenty‐eight (0.7%) implants were considered to have failed and removed within 6 months.Conclusions: The results show that the implants studied obtain a good primary stability with a standard protocol. The IT and RFA appear as two independent features of primary stability. Data show that only IT is influenced by bone density as well as only RFA is correlated to the length of implants used. Finally, it is possible to obtain a good primary stability also in postextractive sites.

Published: September 2010

AbstractThe biology of the fruit fly Bactrocera tau, an important horticultural pest, was studied under laboratory conditions at 25°C and 60–70% relative humidity on Cucurbita maxima. The duration of mating averaged 408.03 ± 235.93 min. After mating, the female fly had a preoviposition period of 11.7 ± 4.49 days. The oviposition rate was 9.9 ± 8.50 eggs and fecundity was 464.6 ± 67.98 eggs/female. Eggs were elliptical, smooth and shiny white, turning darker as hatching approached, and measured 1.30 ± 0.07 mm × 0.24 ± 0.04 mm. The chorion has polygonal microsculpturing and is species‐specific with polygonal walls. The egg period lasts for 1.3 ± 0.41 days. The duration of the larval period is 1.2 ± 0.42, 1.7 ± 0.48 and 4.0 ± 0.94 days for first, second and third instars, respectively. Pupation occurs in the sand or soil and pupal periods are 7.0 ± 0.47 days. The life cycle from egg to adult was completed in 14.2 ± 1.69 days; the longevity of mated females and males was 130.33 ± 14.18 and 104.66 ± 31.21 days, respectively. At least two to three generations were observed from June 2008 to June 2009.
Some reproductive characteristics of honeybee drones in relation to their ages
Authors: MAZEED Adel M. , MOHANNY Karem M. 
Published: September 2010

AbstractThe number of spermatozoa, length of testis, length of mucus gland and weights of drones were estimated in caged and free honeybee drones in relation to their ages. For this purpose, three Carniolan colonies were used as sources of drones and two were used as nursery colonies. The drones were held either in cages or freely in the queenless part of the nursery colonies. Measurements were carried out on samples of drones taken at 3‐day intervals from 1–3, 4–6, 7–9, 10–12 and 13–15 days old. While the number of spermatozoa in drone testes decreased in both caged and free drones as the drone age increased, it increased gradually in the seminal vesicles. The results also showed that weight of drones and length of testes decreased, but the length of the mucus gland did not significantly differ with age. Further, the drones' weight, length of mucus gland and total number of spermatozoa tend to be slightly larger in the caged than in free drones. The total number of spermatozoa in all parts of the reproductive organs was lower in the older than younger drones; thus, the number of spermatozoa in the newly emerged drones does not help to predict the real number reaching the queen during mating.
Use of Antibiotic Sensitivity Tests in Controlling Diseases of Tank‐Raised Pompano
Authors: Monroe Samel R. 
Published: September 2010

ABSTRACTBacteria were isolated from pompano (Trachinotus carolinus) and cultured in the laboratory. Antibiotics were tested against the cultures to determine which were effective in control. Antibiotics which showed promise were incorporated into pompano feed. Success was obtained in control of the bacterial infection.
Marsh Pond Construction
Authors: Perry W. Guthrie , Ensminger Allan B. , Latapie Walter R. 
Published: September 2010

ABSTRACTThis paper reports upon our experiences in the construction of coastal marsh ponds in Louisiana. The 1.7 million ha of marshland offers a wide diversity of conditions, some of which would be applicable to the marsh zones of the other coastal states. The basic marsh types (Active Delta Zone, Inactive Delta Zone and Chenier Plain Zone) are described and pond construction in each is discussed.The soil conditions of the Chenier Plain Zone in southwest Louisiana are generally better suited for the construction and maintenance of long‐term levee systems. Initial cost of marsh pond construction and maintenance is extremely high. This is because levees must be built with equipment specifically designed for marsh work and because of the corrosive nature of the moist, saline environment.
Culture of Brackish‐Freshwater Shrimp, Macrobrachium Acanthurus, M. Carcinus and M. Ohione1
Authors: Dugan Charles C. , Frakes Thomas A. 
Published: September 2010

ABSTRACTMacrobrachium larvae were reared in gradually increasing salinities and in constant salinities of 14, 16, 18, and 20 ppt. Best survival (36%) was achieved not only in an increasing salinity but also in a constant salinity of 16 ppt. In a controlled spawning experiment, temperature was lowered from 27.5 C to 24.0 C for 2 weeks. It was then returned to 27.5 C, and an average of 52.9% of the females tested spawned within 1 week.

Authors: Neal D. A. , Latapie W. R. 
Published: September 2010

ABSTRACTPond cultur̀e experiments were conducted with brown shrimp (Penaeus aztecus) and white shrimp (P. setiferus) in 0.1 ha ponds. All ponds were stocked with juvenile shrimp trawled from the Barataria Bay area. In 1969, there were several types of feed used; in 1970, stocking rates were varied; and in 1971, the feeding rate was varied. The shrimp were fed a specific percentage of their body weight daily. Feeding rates were calculated after a weekly sample of 50 shrimp was taken from each pond, weighed and returned to the pond alive. Results obtained from 44 experiments are compared and discussed. Production ranged from 104 to 931 kg/ha and feed conversion values ranged from 1.1 to 12.6. The heads‐on weight of recovered shrimp ranged from 4.4 to 16 g. Mortalities ranged from 1.6 to 100%.

Authors: Latapie W. R. , Broom J. G. , Neal D. A. 
Published: September 2010

ABSTRACTBrown shrimp (Penaeus aztecus) and white shrimp (P. setiferus) were grown in 0.1 ha artificial ponds at Grand Terre Island, Louisiana. Trawl samples of 50 shrimp from each pond were taken weekly and their average weights determined. Growth curves under various stocking rates, feeds, and times of stocking are presented for both species. Effects of excessive competitors, vegetation, temperature and stocking size are discussed. Generally, white shrimp grew better than brown shrimp. Unfed shrimp grew well until they reached the carrying capacity of the ponds, then stopped or declined slightly. During most of the studies the fed shrimp continued to grow until harvesting, oxygen depletion kills or low water temperatures. Best growth was obtained at stocking rates of 50,000 to 62,500 per ha and feeding rates of 5% to 10% of their body weight daily.
Aquaculture of Sea Scallops and Abalone in Japan
Authors: Shaw William N. 
Published: September 2010

ABSTRACTIn Japan, farming of sea scallops (Patinopecten yessoensis) and abalone (Haliotis discus) is expanding at a rapid rate. Approximately 16 prefectural laboratories are producing 2 to 3 million seed abalone annually. These are sold to the fishermen for planting on natural grounds. Studies are underway to utilize heated water from power plants to speed up the abalone's growth. Plans are also underway to develop artificial growing grounds for abalone culture.Extensive areas in Hokkaido and Mutsu Bay (Honshu) are being utilized in the long‐line culture of scallops. It has been estimated that 40,000 tons of scallops will be harvested in 1972 and 100,000 tons may be produced in 1973.Some of the methods now being utilized to farm scallops and abalone in Japan could possibly be applied in the United States.
A Study of the Effects of Feeding Synthetic Diets to Brown Shrimp (Penaeus aztecus)1
Authors: Hysmith B. T. , Booth J. R. , Cook H. L. , Mies W. L. 
Published: September 2010

ABSTRACTSynthetic diets prepared by Ralston Purina, and commercial pet foods were fed to brown shrimp (Penaeus aztecus) in replicated, 30‐day feeding trials under controlled environmental conditions. A number of Ralston Purina diets were evaluated for palatability.Postlarval hatchery‐raised shrimp and larger stock obtained from the bays were used. Individual lengths and weights of those animals stocked and harvested were used to statistically develop averages from which growth rate, survival, food conversion, and condition index were calculated.Growth rates were found to be related to the size of shrimp, feeding rate, protein content and available metabolizable energy. Survival was found to be related to food availability, disease, and the diet fed. Food conversion was related to the diet requirements of the shrimp and the feeding rate. The condition index was not related to diet and was descriptive of the intermolt stage of the individuals only.As postlarvae, brown shrimp were able to utilize a 45% protein diet effectively when fed at 10% of body weight per day. Development into juveniles changed the relative importance of protein and metabolizable energy in the diet with an accompanying reduction in the food conversion. The growth rates measured in these tests were about half of those measured in the natural habitat and in ponds with supplemental feeding.
Pink Shrimp Feeding Experiments with Wheat Bran1

Published: September 2010

ABSTRACTOther investigators have suggested that detritus enriched by the micro‐organisms that degrade it is a major component of the natural diet of penaeid shrimp. This paper describes pink shrimp (Penaeus duorarum) feeding experiments in earthen ponds and concrete tanks, with wheat bran used to produce an artificial detritus food for the shrimp. Wheat bran and other foods are compared, and the effects of food type, feeding methods, and certain aspects of water quality on growth, survival and yield of pink shrimp are evaluated.The artificial detritus method of feeding in the culture of shrimp is much simpler than the feeding of pelleted or other diets directly to shrimp, since the former does not depend upon monitoring of growth rates and population densities to determine feeding rates. Wheat bran is added to unaerated tanks or ponds at constant rates that do not cause oxygen depletion. We have added wheat bran to ponds at daily rates up to 35 kg per ha without causing obvious problems.With wheat bran feeding, it seems possible to rear postlarval pink shrimp in ponds or tanks to about 4 g (live bait size) in 3 months and at stocking densities as high as 100,000 per ha, and with survival as high as 90%. Our investigations of the artificial detritus feeding method will continue with the goal of developing methods for producing food shrimp profitably.
Growth of Hatchery‐Reared Penaeus Aztecus on Experimental Diets1
Authors: Grajcer D. , Neal R. 
Published: September 2010

ABSTRACTDuring experimentation designed to determine the requirements for sexual maturation of brown shrimp (Penaeus aztecus) a series of diets were tested on juvenile and subadult shrimp. These diets were formulated from a series of compounds expected to provide the essential nutrients for growth and sexual maturation. Both natural and prepared foods (i.e., foods which have been processed for storage at room temperature) were tested. The ingredients of the foods tested and the processing methods used to stabilize the foods are described.Growth rates and amounts of food consumed for shrimp reared on these diets are discussed, and growth is compared with that observed for wild shrimp. Implications of these growth rates to shrimp cultures are discussed. Experimental stunting of juvenile shrimp was investigated as a means of storing excess animals temporarily.
SOME RESULTS OF A PILOT PROJECT ON FRESHWATER PRAWN CULTURE IN JAMAICA
Authors: Provenzano Anthony J. 
Published: September 2010

ABSTRACTThree ponds constructed in southwest Jamaica were stocked with postlarval and juvenile Macrobrachium rosenbergii which had been reared at Ocean Protein Corporation's hatchery in Dania, Florida. Results from one 0.2 ha pond are presented. A variety of commercial and experimental chows was fed. No attempt was made to estimate the population between stocking and harvesting. Growth was considered satisfactory. Bird predation appeared to be a factor in overall mortalities, but did not prevent substantial qualities from being harvested.
POSSIBLE USES OF PELAGIC SEAWEED AS A MARICULTURE SUBSTRATE
Authors: Werner Edgar , Harris James A. 
Published: September 2010

ABSTRACTOpen‐ocean mariculture might have considerable advantages in large‐scale production over usual tank and closed‐bay techniques. Most of the benefits would lie in the elimination of closed systems which require extensive power for water circulation and are subject to the rapid spread of chemical pollutants and disease. In tropical and subtropical waters pelagic sargassum is suggested as a medium for mariculture. Sargassum could be utilized in shallow water as cover, with the concomitant life forms (i.e. plankton, crustaceans, etc.) as a food supply for juveniles such as Coryphaena sp. Some benthic forms, molluska for example, might produce higher yields under cover of sargassum than on reefs or platforms. Studies could also be made on the relationship of seaweed to eels and turtles with a view towards developing culture methods. Deep water platforms might be based under the sargassum mass to eliminate pollution problems associated with nearby land masses.As a byproduct of mariculture, the sargassum would provide the basis for a local alginate extraction industry.
CAGE CULTURE OF SOME MARINE FISHES IN THE INTAKE AND DISCHARGE CANALS OF A STEAM — ELECTRIC GENERATING STATION, GALVESTON BAY, TEXAS
Authors: Marcello Rocco A. , Strawn Kirk 
Published: September 2010

ABSTRACTSeveral species of marine fishes were cultured in cages in the intake and discharge canals of the P. H. Robinson Generating Station on Galveston Bay, Texas. Survival in the intake canal cages of Atlantic croaker (Micropogon undulatus), pinfish (Lagodon rhomboides), Florida pompano (Trachinotus carolinus), white mullet (Mugil curema), spot (Leiostomus xanthurus), and black drum (Pogonias cromis) was on the average 70% or greater, while that of pigfish (Orthopristis chrysoptera), Gulf kingfish (Menticirrhus littoralis), and silver perch (Bairdiella chrysura) was less than 70%. With the exception of pinfish, survival of caged fish in the discharge canal was extremely poor. Gas‐bubble disease was the probable cause of their mortality. Only croaker and pompano adapted to surface feeding in cages. Croaker, pinfish, and pompano cultured in cages were rated acceptable by a 12‐member taste panel. Mean taste evaluation scores for croaker, pinfish, and pompano for the appearance, flavor, and overall satisfaction categories were not significantly different (P=0.01). After about 1 year in the water, most cages used in the intake canal were in goad condition, but those located in the discharge canal were in poor condition.
SALMONID CULTURE IN CLOSED SYSTEMS
Authors: Meade Thomas L. 
Published: September 2010

ABSTRACTThe production of salmonids has been a continuing goal of the University of Rhode Island, Marine Experiment Station since 1968. Unfavorable climatic and hydrological conditions necessitated the adoption of cultural systems capable of sustained production. All phases of production from incubation to grow out have been carried out in a controlled environment water re‐use system. Problems encountered in the development and operation of these systems are discussed. Data developed to date indicate that water re‐use systems are technically feasible for all phases of production and dependence upon large volumes of high quality natural water are greatly reduced. Preliminary studies also indicate that marine environments suitable for salmonid culture can be created and maintained at locations remote from the coast.
COMPARATIVE GROWTH OF POMPANO (Trachinotus carolinus) IN SUSPENDED CAGES RECEIVING DIETS OF A FLOATING TROUT CHOW WITH THOSE RECEIVING A MIXTURE OF 50% TROUT CHOW AND 50% SINKING RATION
Authors: Tatum Walter M. 
Published: September 2010

ABSTRACTThe Alabama Marine Resources Division has been engaged in culturing pompano (Trachinotus carolinus Lin.) in suspended cages since 1969. Tests in 1972 demonstrated that Purina Trout Chow (a complete floating ration) was superior to a complete sinking ration for pompano in gain produced, food conversion and percent survival. Stocking densities of 263, 394, 526 to 657 pompano/m3 cage volume demonstrated that individual growth was best at the lower stocking densities but that total weight gained/cage was best at the higher stocking densities. A maximum standing crop of 49.5 kg of pompano/m3 cage volume was attained during the 103‐day culture period.
