Exigência de lisina digestível para poedeiras semipesadas de 50 a 66 semanas de idade / Digestible lysine requirement for laying hens from 50 to 66 weeks of age

Com o objetivo de determinar a exigência de lisina digestível para poedeiras semipesadas no período de 50 a 66 semanas de idade, foi realizado experimento utilizando-se 150 poedeiras Shaver Brown, distribuídas em delineamento inteiramente ao acaso, com cinco tratamentos (níveis de lisina digestível: 0,79; 0,82; 0,85; 0,88 e 0,91%), seis repetições e cinco aves por unidade experimental. Foram avaliados a produção de ovos, peso médio e a massa de ovos, consumo de ração e de lisina, conversão alimentar por massa e por dúzia de ovos, gravidade específica, unidade Haugh, o índice de gema e albúmen, porcentagem de albúmen, gema e casca. O consumo de ração, a conversão alimentar por massa e dúzia de ovos, a produção, o peso e a massa de ovos não foram influenciados (P>0,05) pelos níveis de lisina digestível. Houve aumento linear no consumo de lisina (P<0,01) com o incremento dos níveis desse aminoácido nas rações. As porcentagens de albúmen, gema e casca não foram influenciadas (P>0,05) pelos níveis de lisina digestível estudados. Os níveis de lisina influenciaram de forma quadrática (P>0,05) a unidade Haugh e o índice de albúmen, sendo estimados os níveis de 0,884 e 0,868% de lisina digestível, respectivamente. Para o índice de gema, a associação do modelo quadrático ao Linear Response Plateau (LRP) estimou o nível de 0,903% de lisina digestível. Quando o objetivo é maximizar a qualidade interna dos ovos, recomenda-se o nível dietético de 0,884%, 0,868% e 0,903% de lisina digestível para unidade Haugh, índice de albúmen e índice de gema, respectivamente.

With the objective of determining the requirement of digestible lysine for brown-egg laying hens in the period from 50 to 66 weeks of age, an experiment was carried out using 150 Shaver Brown laying hens, distributed in a completely randomized design, with five treatments (digestible lysine levels: 0.79, 0.82, 0.85, 0.88 and 0.91%), six replications and five birds per experimental unit. The production of eggs, weight and the egg mass, feed intake and lysine, feed mass and dozen eggs, specific gravity, Haugh unit, yolk and albumen index, percentage of albumen, yolk and bark were analyzed. Feed intake, feed conversion per dozen of eggs s and per egg mass, egg production, egg weight and egg mass were not influenced (P>0.05) by digestible lysine levels. There was a linear increase in lysine intake (P<0.01) with increasing levels of this amino acid in the diets. The albumen, yolk and shell percentages were not influenced (P>0.05) by studied digestible lysine levels. Lysine levels had a quadratic effect (P>0.05) Haugh unit and albumen index being estimated as 0.884 and 0.868% digestible lysine levels, respectively. For yolk index, the association of the quadratic model to Linear Response Plateau (LRP) estimated the level of 0.903% digestible lysine. When the aim is to maximize the internal egg quality, a dietary level of 0.884%, 0.868% and 0.903% digestible lysine for Haugh unit, albumen index and yolk index, respectively is recommended.

Keloids Treated with a Suction-Assisted Cartilage Shaver: A Report of Four Cases / 대한피부과학회지

Surgical excision of keloids is generally not accepted as a first treatment option, but many reports have described specialized surgical methods, such as intralesional and intramarginal excision. This operation preserves the active peripheral portion of the keloid and excises the central bulky lesion. The suprakeloidal flap technique and keloid core excision involve intralesional excision. These methods are known to be associated with a low probability of recurrence or lesion exacerbation because the remaining keloidal lesion acts as a barrier. However, several complications, such as partial necrosis and flap congestion, have been reported, especially in large lesions. We describe cases of four patients with keloids on the chest or abdomen. All patients complained of pain or itching due to the keloids. Patient age ranged from 20 years to 54 years, and the number of lesions ranged from one to seven. The largest lesion measured 10x8 cm. We treated the lesions by the dermal shaving method using a suction-assisted cartilage shaver, and the lesions were markedly flattened in all cases. Because this surgery is performed through an incision for a cannula, it allows more rapid healing and causes less postoperative pain with fewer severe complications. It also has the advantage of requiring less effort and time due to the use of motorized curettage with suction. The suction-assisted cartilage shaver using dermal shaving method seems to be an effective alternative treatment modality for reducing the lesional size of keloids.

Efficacy and Safety of Suction-assisted Cartilage Shaver with Fibrin Glue in Treating Axillary Osmidrosis / 대한피부과학회지

BACKGROUND: Axillary osmidrosis causes significant emotional distress and embarrassment. Although numerous surgical procedures have been developed for the treatment of axillary osmidrosis, there is no decisively effective one. OBJECTIVE: This paper is to assess the efficacy and safety of suction-assisted cartilage shaver with the use of fibrin glue to treat axillary osmidrosis. METHODS: 18 axillary osmidrosis patients were treated with suction-assisted cartilage shaver followed by injection of fibrin glue. The effectiveness of the treatment used in this study was evaluated by measurement of axillary malodor both pre- and postoperatively. Patient satisfaction was surveyed as well. RESULTS: The postoperative test demonstrated that there was remarkable decrease in axillary malodor. Of the 18 patients, 17 patients (94.4%) expressed positive satisfaction. Complications including postinflammatory hyper-pigmentation (27.8%), hematoma and skin necrosis (5.6%), scar (5.6%), infection (5.6%) and hidradenitis suppurativa (2.8%) were reported. CONCLUSION: The use of suction-assisted cartilage shaver with fibrin glue proved itself an effective and safe treatment for axillary ormidrosis.

Multiple Piloleiomyoma Treated with a Suction-Assisted Cartilage Shaver / 대한피부과학회지

Piloleiomyoma is a benign neoplasm arising from the erector pili muscle in the skin. It occurs as linear or dermatomal arrangements of firm, red to brown intradermal nodules, which are fixed to the skin but not to the deeper tissues. Although various treatments have been attempted, they have shown limited success and several complications remain. A 21-year-old male presented with 3-year history of multiple, erythematous, firm 4 mm to 3 cm sized nodules on the chest. The histopathological examination was compatible with piloleiomyoma. The lesions were removed using the dermal shaving method with a suction-assisted cartilage shaver. Each lesion were markedly flattened. This treatment was quicker and caused less subjective pain to the patient compared with those of classic surgical excision. No signs of adverse events or recurrence have been observed.

A Case of Arthroscopic Excision of Synovial Hemangioma with Dual Coagulation Shaver

A 17-year-old male patient visited our hospital with a palpable mass on the lateral aspect of the knee joint of five years duration without any related trauma history. The patient felt tenderness around the mass and had limitations in doing flexion exercises. Magnetic resonance imaging of the knee suggested the possibility of synovial hemangioma, and thus surgical treatment was planned. A tumor within the knee joint was found by arthroscopy, and a resection was carried out by dual coagulation shaver. The biopsy confirmed the diagnosis of a synovial hemangiomas. The patient presented months later at the out-patient clinic with no evidence of recurrence.

Steatocystoma Multiplex Treated with a Suction-assisted Cartilage Shaver / 대한피부과학회지

Steatocystoma multiplex is a rare autosomal-dominant disorder characterized by asymptomatic multiple, skin-colored to yellowish nodules on the trunk, proximal extremities, and axillae. Although surgical excision is the most effective method, treatment is difficult when lesions occur in multiple numbers. Therefore, various treatments such as CO2 laser therapy, needle aspiration, and oral isotretinoin have been attempted, but results are variable. A 37-year-old man presented with multiple skin-colored subcutaneous nodules on the abdomen and both axillae. A histopathological examination was consistent with steatocystoma multiplex. The lesions were removed by dermal shaving with a suction-assisted cartilage shaver. It was an effective therapeutic method for multiple lesions with no significant adverse events. Herein, we report a case of steatocystoma multiplex treated with a suction-assisted cartilage shaver.

The Treatment of Gynecomastia using XPS(R) Microresector (Shaver)

PURPOSE: Gynecomastia is an abnormal increase in the volume of the male breast. Subcutaneous mastectomy was the first surgical treatment for gynecomastia. But because of the complications such as nerve injury and scar formation, subcutaneous mastectomy has been substituted with liposuction. Recently various techniques including ultrasound-assisted liposuction has been used for treatment of gynecomastia. The purpose of this study is to evaluate the results of XPS(R) microresector (Shaver) for treatment of gynecomastia. METHODS: 17 patients, 33 breasts of gynecomastia, Simon grade I or II have been treated with XPS(R) microresector (Shaver). The mean age was 24.5. The subcutaneous tissue and glandular tissue were removed with XPS(R) microresector (Shaver). The operation time, the weight of removed tissue and patients' satisfaction score were accessed. RESULTS: The mean operation time was 78.2 minutes. The mean weight of removed tissue was 113.8 g. There were no significant complications such as necrosis, hematoma, infection or scar contracture. Patients' satisfactory score of scar, shape and confidence were 8.4, 8.2 and 8.4 respectively. As the average score was 8.3, most of the patients were satisfied with their breasts. CONCLUSION: The authors have treated 17 patients suffering from gynecomastia with XPS(R) microresector (Shaver). We obtained short operation time, early recovery, minimal operative scar and less complications with XPS(R) microresector (Shaver) for the treatment of gynecomastia, and patients were satisfied with the results of our method. We concluded that XPS(R) microresector (Shaver) is an alternative option for the treatment of gynecomastia.

XPS(R) Microresector for Treatment of Axillary

PURPOSE: Surgical excision of the subcutaneous tissues, with or without skin excision in the axillary hair-bearing area, has been the treatment of choice in treating osmidrosis for several decades. However, long periods of postoperative immobilization of a shoulder joint, partial necrosis of skin flaps or the possibility of hematoma and scars have occurred frequently. So we used XPS(R) microresector(Shaver) in procedure which requires removal of soft tissue for comparing results between surgical excision and the laters. METHODS: From January 2007 to February 2008, a total of 20 patients(8 male and 12 female) underwent XPS(R) microresector(Shaver) assisted aspiration for treating osmidrosis. The mean age of the subjects was 21.9, and we tried to analyze some advantages of XPS(R) microresector(Shaver). RESULTS: The average operation time was 61.6 minutes. This results can show that the patients who received XPS(R) microresector(Shaver) assisted aspiration can accomplish better outcomes than any other procedures in terms of operation time at least. Moreover, no significant postoperative complications occurred in our studies. Subjects have been followed up from 2 months to 1 year and among these patients, no one suffered from critical complications. CONCLUSION: In brief, XPS(R) microresector(Shaver) is able to shorten the time of operation and simplify the procedures relatively and this device has more superiorities in wound healing by maintaining of vascularized dermal skin flaps. It means that XPS(R) microresector (Shaver) can prevent flap necrosis, axillary hair loss and minimalize scarring and bleeding. Thus, we expect that these advantages can lead to better patient's comfort and self-confidence than several previous procedures.

Clinical Study of the Surgical Excision of Subcutaneous Tissue Combined with the Assistant Subcutaneous Shaver Method for treatment of Axillary Osmidrosis and Hyperhidrosis / 대한피부과학회지

BACKGROUND: Classical surgical treatment of axillary osmidrosis and hyperhidrosis results in many complications such as scarring, hematoma and necrosis, therefore, gentle skin flap cares is needed. OBJECTIVE: In order to lessen the complications and to obtain an improved clinical outcome, a new easy-learn, surgical excision method of treating subcutaneous tissue is required. METHOD: On 16 patients, We carried out a type-1 surgical method to treat axillary osmidrosis and hyperhidrosis. This invoved major removal of the subcutaneous tissue by scissor excision, and partial removal by the subwtaneous shaver method, to minimise trauma. We then analyzed the clinical efficiency, complications, patient satisfaction, and pathologic specimens according to clinical severity. RESULTS: All 16 patients showed an improved odor or sweating pattern, and a good or very good level of satisfaction. One patient also showed that hematoma was improved with proper post- operative care. Hyperactivity of the apocrine glands in osmidrosis and eccrine gland in hyperhidrosis was seen, and various morphologic features of apoeccrine glands were found in both osmidrosis and hyperhidrosis. We observed that apocrine and eccrine glands were completely excised by following the biopsy of 2 patients. CONCLUSION: Our present method of minimal skin incision and major removal of subcutaneous fat with manual scissor excision, in combination with partial excision with the subcutaneous shaver method, showed a good clinical outcome and few complications.

Treatment of Large Lipoma by Arthroscopic Shaver / 대한피부과학회지

Lipoma is one of the most common benign tumors of soft tissue which tends to be left untreated due to unremarkable clinical features and its property of slow growth. It comes to clinical attention only when it causes concern of malignancy because of inordinate size or is perceived as faults in need of cosmetic removal and consequently the incision line is, frequently long and may result in high risk of intra- and postoperative complications such as hematoma and hypertropic scars. So it requires cosmetically acceptable and convenient methods for treatment of lipoma, especially located in the exposed area. The liposuction was tried to get less complications and smaller incision line. But for deep seated variants of lipoma they tend to be less well-circumscribed and often have thick fibrous septa around the lipoma, simple liposuction showed some limitations. So we tried the new liposuction method using arthroscopic shaver for 5 patients having lipomas larger than 5 cm in diameter. The surgery was performed with arthroscopic shaver system equipped with a motorized blade rotating in the suction cannula and emulsifying the lipoma tissue for easy aspiration. The aspirated material was collected and examined histopathologically to rule out the evidence of malignancy. Lipomas were removed completely without any remarkable complications, and no recurrence was seen till three years after surgery. The new method was easier to operate and took less operation time and left only small incision line.

Treatment of Axillary Hyperhidrosis; Manual Subdermal Excision Combined with the Tumescent Liposuction and Subcutaneous Tissue Shaver

BACKGROUND: Axillary osmidrosis is a distressing problem characterized by unpleasant odor, profuse sweating, and occasional wetting of clothes that may handicap those affected both socially and psychologically. A variety of surgical methods have been developed for the treatment of axillary osmidrosis. OBJECTIVE: To introduce the manual subdermal excision combined with the tumescent liposuction and subcutaneous tissue shaver for axillary osmidrosis. METHODS: Twenty-five patients with axillary osmidrosis were treated by the manual subdermal excision combined with the tumescent liposuction and subcutaneous tissue shaver. RESULTS: Twenty-one(84%) patients had good results, four(16%) fair, and none had a poor result or recurrence. Complications included one case of hematoma, two cases of partial skin necrosis. The wound complication rate was 6.0%(3/50) for the axilla and 12%(3/25) for patients. CONCLUSION: The manual subdermal excision combined with the tumescent liposuction and subcutaneous tissue shaver is effective surgical procedure for the treatment of axillary osmidrosis with a low complication rate and recurrence.

Powered Laryngeal Shaver for Papilloma of the Larynx in Children by Laryngeal Endoscopy / 中国微创外科杂志

Objective To investigate the outcome of powered laryngeal shaver for papilloma of the larynx in children by laryngeal endoscopy. Methods Thirty-nine children with papilloma of the larynx were treated by powered laryngeal shaver under a laryngeal endoscope. Twenty-seven of the patients who had an extensive tumor received radiofrequency to avoid hemorrhage and adhesion of the surgical surface. Results The mean operation time was (11.2?2.6) min, and the blood lose was less than 30 ml. Three months after the operation, 28 of the patients were fond of their voice quality. Among the 39 patients, 37 were followed up for 2-5 years, during which 3-year recurrence rate was 51% (19/37). In the children with primary patients, the rate of recurrence was 30% (3/10), and in those with recurrent tumor, the rate was 59% (16/27). Conclusions By using powered laryngeal shaver under a laryngeal endoscope, papilloma of the larynx can be accurately resected with low blood loss, short operation time and short hospital stay and confirmed effectivenss.

Combination Treatment of Osmidrosis by Liposuction and Endoscopic Shaver

Many surgical procedures have been introduced for treatment of axillary osmidrosis, but some complications, such as symptom recurrence, hematoma, seroma, delayed wound healing, skin flap necrosis and scarring, are not solved yet. Recently introduced liposuction method has several advantages over previous surgical methods, such as increased skin flap vascularity, minimal scarring and bleeding, etc, but the sympton recurrence rate has been reported 10-30%. Liposuction method could remove apocrine glands in subcutaneous tissue effectively, but the glands firmly seated in subdermis remain as the cause of sympton recurrence. For this reason, we employed combination treatment of liposuction and endoscopic subdermal shaving method. From March 1997 to February 2001, a total 71 patients (24 men and 47 women) had been treated with this procedure for bilateral axillary osmidrosis. In our procedure, apocrine glands in subcutaneous tissue were removed by liposuction method and the glands in subdermis were removed by using 4.5 mm incisor blade of endoscopic shaver. Follow-up evaluation period was from 3months to 24 months, and the results were satisfactory. No one suffered from sympton recurrence. Postoperative scar was negligible (below 0.5 cm) and other complications were minimal.

The Effects of the Shaver for the Treatment of the Chronic ParanasalSinusitis on Operating Time and Postoperative Pain / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Functional endoscopic sinus surgery (FESS) is an effective treatment for chronic sinusitis and nasal polyposis. But the extent of surgery is one of the major issues in FESS. To solve this problem, the shaver has been used from 1992. It dramatically reduced inadvertent trauma to nasal mucosa and improved visualization and tissue healing after surgery. This study is aimed at evaluating the clinical value of the shaver with degree of postoperative pain and the time required for surgery. MATERIALS AND METHODS: We studied bilateral chronic paranasal sinusitis patients of whom, 28 were operated with the shaver, and 15 cases were operated with the conventional instrument. This study evaluated the postoperative pain using Visual Analogue Scores (VAS) at 2, 6, 24 and 48 hours after operation and the time required for surgery. The results were then compared with the preoperative computed tomographic radiological staging and surgery scores. RESULTS: For the shaver group, the time requirement for FESS and the postoperative pain scores were much lower than the conventional instrument group. CONCLUSION: The shaver is a very useful instrument for sinus surgery and it can reduce surgical time and the discomfortness for the patient.
