Difficulties in the treatment of hypospadias in boys persist to this day. After surgical correction of hypospadias, fistulas, strictures, urethral diverticula, retraction of the meatus, glans dehiscence and other complications occur. At the same time, it is quite difficult to understand the whole variety of proposed methods for correcting hypospadias, which creates confusion for specialists and negatively affects the results of treatment. The literature describes more than 300 different methods of correcting hypospadias, but none of the methods is perfect, and there are no generally accepted treatment standards. Despite this, it is an established fact that the choice of the surgery procedure depends on the type of hypospadias. A successful technique of hypospadias repair should be completed with a good cosmetic and functional result. The article presents an overview of the distension techniques of urethroplasty. For the first time, the experience of urethral advancement was presented at the end of the XIX century, but the technique was unpopular and did not have significant success. However, by the end of the XX century, more effective distension techniques of urethroplasty began to be developed, which were widely used around the world (Koff S.A., Ti-Seng Chang, Belman A.B., MAGPI, LUM, etc.). According to scientific literature, urethral advancement is a safe and reliable way to correct distal hypospadias, and it is considered as an alternative to creating a neourethra. This technique has many competitive advantages, such as the short operation time, the absence of urethral tubularization, excellent functional and cosmetic results, and a small number of complications. It, therefore, follows that distension techniques of urethroplasty are considered a good option for correcting distal hypospadias, which should be in the arsenal of every pediatric surgeon and urologist.

Background: Different laser types have been used for the treatment of hypertrophied inferiornasal turbinates. The clinical experiences of its treatment by means of a diode laser are presented.Methods: A total of 45 patients suffering from nasal obstruction due to hypertrophied inferiorturbinates (HIT) were treated with a continuous diode laser (14 W- 940 nm) in "contact" modeand under local anesthesia. Thirty patients (16 with allergic rhinitis and 14 with vasomotorrhinitis) were included into this clinical trial with a follow-up of 6 months. The study wasconducted by a questionnaire, photo documentation, conventional radiology of the paranasalsinuses, and histology.Results: The mean operation time took 8 min/turbinate, no nasal packing was necessary andno immediate complications (e.g., bleeding) were observed. Statistical analysis revealedsignificant subjective improvement (86%) of the nasal airflow and nasal cavity volume (photodocumentation) 6 months after laser surgery. In addition, complete relief of headache wasachieved in 32%. The remission rates of persistent rhinorrhoea and post-nasal dripping were,at about 88% and 64%, respectively. Atrophic change and synechiae had not been observed.Conclusions: Diode laser treatment of HIT is a useful procedure, which can be performed as anoutpatient surgery under local anesthesia, resulting in a controlled coagulation and ablation of thesoft tissue. The short operation time and the good results provide an excellent patient acceptance.Key words: Diode Laser; Hypertrophied Inferior Turbinate; Turbinoplasty.DOI: 10.3329/bjo.v16i1.5778Bangladesh J Otorhinolaryngol 2010; 16(1): 29-34

Anal fistula (AF) is a pathological connection between anus and skin in its surroundings. The main reason for the formation of anal fistula is a bacterial infection of the glands within the anal crypts. One of the modern techniques for the treatment of fistulas that do not interfere with the sphincters consists in implantation of a plug made from collagen material. We are presenting the first Polish experience with a new model of biomaterial plug for the treatment of anal fistula. We also point out key elements of the procedure (both preoperative and intraoperative) associated with this method. In the authors’ opinion, the method is simple, safe and reproducible. Innovative shape of the plug minimizes the risk of its migration and rotation. It also perfectly blends with and adapts to the course and shape of the fistula canal, allowing it to become incorporated and overgrown with tissue in the fistula canal. The relatively short operation time, minor postoperative pain and faster convalescence are with no doubt additional advantages of the method. Long-term observation involving more patients is essential for evaluation of the efficacy of the treatment of fistulas with the new type of plug.

Trichothecenes are a family of major secondary metabolites produced by some common filamentous fungi, including plant pathogenic and entomopathogenic fungi. It may be considered difficult to conduct a comparison between the toxicities of trichothecenes with consideration of different conditions and cell lines. In the current study, we developed an in vitro assay based on a commercially available system to estimate the translation inhibition, that is, the main toxicity, of trichothecenes. The assay was applied to estimate the inhibition of protein synthesis by trichothecenes. Initially, we examined the assay using trichothecene dissolved in water followed by an assessment of trichothecene solutions dissolved in acetonitrile. The obtained data showed that the assay tolerated the small amount of acetonitrile. The assay examined in this study has the advantages of a short operation time (one day), ease of use, and data stability, as it is a non-cell-based assay whose components are commercially available. It is expected that this assay will contribute to the evaluation of the toxicity of a vast number of trichothecenes.

Hemangiomas are the most common tumors in infancy constituting 1 – 2.6 % of incidence. Their incidence in preterm newborns with low birth weight (less than 1000 g) can reach 30 %. Increase in the incidence is observed during the first year of life.Regressing hemangiomas undergo careful observation. Hemangiomas with a high risk of complications (destructive growth, cosmetic defects, ulceration, amblyopia, compression of vital structures) require treatment.The variety of clinical and morphological features, localization and prevalence of vascular lesions require continual search for effective methods of treatment to determine the optimal terms and methods of therapy.The objective of the research was to improvement the results of hemangiomas treatment in children.Materials and methods. The results of treatment of 146 children with voluminous, rapidly growing, and non-regressing hemangiomas, as well as children with poor results of treatment after incorrect therapy were analyzed.Methods of the research included clinical, morphological, radiation, statistical ones.Results and discussion. Effectual treatment regimen of rapidly growing and non-regressing hemangiomas with cosmetically important locations, including surgical treatment with the use of high-frequency coagulator EC-300MІ and systemic therapy with propranolol was developed and suggested.Conclusions. The proposed treatment regimen reduces the volume and intensity of hemangiomas growth. In the majority of cases it allows complete removal of the tumor with a good cosmetic result.

<p>Iron (III) (Fe (III)) is widely used in the industry such us water treatment, the sugar cane, the concrete industry and coal mining. Industrial activity using Fe(III) has potential impact to environmental pollution problems due to that industry produces Fe waste that one of hazardous waste. Fe content excess might toxic effect to human health and the environment. Zeolite as adsorbent has been evaluated extensively for Fe and other heavy metal. Sonication method has been widely developed in polymer preparation. The method is more effective in operation time because the reaction rate increased and also more efficient on the usage of chemical reagens. The optimization of reaction time, the ratio of Fe(III) with activated zeolite, the influence of pH, and temperature has been assessed for Fe(III) adsorption with an activated zeolite by sonication technique. The formation of Fe(III)-SCN complex assay was used for determination of Fe(III) adsorbed by the activated zeolite with using spectrophotometer. The results showed a relatively short operation time (15 minutes), at pH of 4, temperature of  30 °C with the ratio of 1:50 (weight/volume) for the activated zeolite and Fe(III). </p>

This study provides an overview of the effects of prolonged acid attack on the surface of PTFE gaskets, assessed using Fourier Transform Infrared Spectroscopy (FT-IR), Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC). The PTFE analysed originates from two manufacturers in form of Teflon adhesive tapes, used as gaskets in an ultrasonic tyre moulds cleaning plant (UMCS). The gaskets were exposed to various acid baths, temperature and ultrasonic waves, and shown anomalous damage and surface degradation in a relatively short operation time. The analyses here reported have been aimed at investigating this unusual behaviour. PTFE samples have been treated with different acid mixes to evaluate possible different aging effects. Both surface and core have been analysed after aging, providing evidence of the degradation phenomena. In particular, different acid treatments have highlighted different response of PTFE and differences among manufacturers.

Purpose: to conduct a comparative assessment of the effectiveness and safety of laparoscopic kidney resections for benign and malignant neoplasms with and without vascular isolation of the organ. Materials and methods: the research presents a comparative analysis of the direct results of treatment of 182 patients who underwent laparoscopic kidney resection. Among them there were 94 men (51,7 %) and 88 women (48,3 %). The average age was 61,6 ± 6,2 years. Two main methods were used: kidney resection with vascular isolation and without vascular ischemia. Surgical treatment was performed for malignant neoplasms in 152 cases (86,5 %) and for benign neoplasms in 24 cases (13,6 %). We used the methods of laparoscopic resection of the kidney with total vascular ischemia in 44 cases (24,2 %) and without vascular ischemia in 138 patients (75,8 %). Results: the average duration of surgery was 80 ± 18,5 minutes. The average duration of the operation with the use of vascular ischemia was 122,1 ± 17,5 minutes, without ischemia — 81,7 ± 10,6 minutes. The volume of intraoperative blood loss averaged 174,4 ± 20,1 ml, while this indicator when using the ischemic-free technique was 154,2 ± 15,7 ml, which is 32,9 % less (p> 0,05) than in cases with the use of vascular isolation (230,1 ± 20,8 ml). When using the technique of vascular isolation, the serum creatinine has increased for 16,2 ± 1,7 μmol / L (16,7 %), without vascular isolation 6,5 ± 1,5 μmol / L (6,7 %). Conclusion: laparoscopic kidney resections without vascular isolation are characterized by a lower volume of intraoperative blood loss, a shorter operation time and are not accompanied by an increase in the number of postoperative complications.

The injure of the ureter it is one of the most frequent complications in gynecological surgery and occurs according to the literature in the 0.5-30%. There is a great variety of methods of surgical treatment of ureteral injuries, including using modern minimally invasive technologies. But the truth borders of ureteral defeat often differ from the perceived visually, which may cause failures of surgical correction. Application of electroureterography can objectively determine the limits and in accordance defeat ureter level of resection. At the same time the literature have not marks about using of assessment electroureterography during the choose a method of correction of ureteral injury. The objective: to improve the results of treatment of ureteral injury during obstetric – gynecological surgery by improving methods of surgical correction. Patients and methods. In the basis researches are the results of clinical observations of 60 patients who performed surgical correction of ureteral injury. The main group of patients represented by 23 (38.3±12.3%) patients, whose injuries correction performed by laparoscopic and classical open access using the electroureterography. In the first control group operative treatment was subjected 21 (35±12.1%) patients who performed a similar surgery but without using electroureterography. In the second control group of 16 (26.7±11.2%) patients made ureteroscopy and installing JJ-stent, and mandatory condition was absence of ureteral wall defect. Results. The results of treatment assessed considering the subjective and objective criteria by the system of three marks as good, satisfactory and unsatisfactory. Among the 23 patients who were performed surgery using electroureterography, 20 (87±13.7%) patients had a good results. 3 (13±13.8%) patients results were evaluated as satisfactory. Bad results were not observed. 21 patients who performed laparoscopic surgery and by open access without using of electroureterography, founded that 8 (38.1±20.7%) patients had a good results. 9 (42.9±21.1%) patients results were evaluated as satisfactory, and 4 (19±16.8%) patients regarded as bad. Among the 16 patients who performed ureteroscopy with ureteral stenting, in 11 (68.8±22.7%) patients the results were evaluated as good. Five (31.2±22.7%) patients with satisfactory results correspond. Bad results were not observed, it is connected with initial mild ureteral injury in this group of patients (Grade I, classifies Organ Injury Scaling System). Conclusions. Using the electroureterography during the reconstructive operations has reduced the poor results by 19% compared to similar transactions without using this method. This explained that electroureterografy allows to objectively determine the limits of the ureteric defeat and accordingly level of his resection, and the most appropriate type of surgical treatment of trauma. In the turn, ureteral injury correction using ureteroscopy and stenting, is highly effective if used in patients with mild injuries (Grade I, classifies Organ Injury Scaling System). Key words: ureteral injury, treatment, gynecological surgery, electroureterography.

Abstract Background A prospective study was conducted on 65 cases with distal hypospadias operated using the urethral mobilization technique between July 2017 and December 2019. Patients with proximal hypospadias and those with distal hypospadias, but with a hypoplastic urethra, were excluded from the study. In this technique, the urethral tube was mobilized proximally in a ratio of 3–4:1 (the ratio of mobilized urethral length to the initial distance between the native meatus and the tip of the glans) then positioned distally after creating wide glans wings. The aim of this study was to assess the outcome of the urethral mobilization technique in distal hypospadias in our center. Results The age of patients was ranged 9 months to 7 years old (mean 37.5 months); 17 (26%) cases were already circumcised. During the postoperative follow-up, 62 (95.4%) patients had a good caliber neomeatus with a good and straight urinary stream; the remaining 3 (4.6%) cases developed meatal stenosis which responded well to urethral dilatation. One (1.5%) patient had a minor retraction of neomeatus but remained within the glans and not requiring further intervention. Four (6%) cases developed minor hematoma which was resolved on conservative measures. Six (9.2%) patients developed minor wound infection which was treated with daily dressing and antibiotic coverage. Conclusion The urethral mobilization technique is a good choice for repairing distal hypospadias especially for boys who are previously circumcised as the preputial flap is not required in this technique. It provides good cosmetic and functional results, with a fewer complication rate.
