Bamboo filaments were treated with boric acid and borax (the mass ratio of 1:1, the concentration of 20%) with four different treatment methods including atmospheric immersion, cold and hot bath immersion, vacuum impregnation and vacuum-pressure impregnation. The different treatment methods on the boron loading were analyzed and the corresponding flame resistance of bamboo filaments were evaluated by the cone analysis. The results showed that suitable treatment method with optimized processing indexes, such as hot and cold bath immersion in the condition of 100°C/2 h and 20°C/2 h with 3 cycles, was more credible to accelerate the percentages of boron loading in the bamboo filaments, and the lowest result was found in the samples with vacuum impregnation. Compared to the untreated samples, the heat and smoke release would be decreased significantly, especially for the samples with the promising hot and cold treatment, and promising pressure treatment, attributed to the more stable boron fixed in the bamboo filaments.

Összefoglaló. Bevezetés: Szemhéjcsüngésnek (ptosis vagy blepharoptosis) nevezzük azt az állapotot, amikor a felső szemhéj abnormálisan alacsony pozícióban van. A szemhéjcsüngésnek lehetnek veleszületett és szerzett formái. Célkitűzés: Célunk volt bemutatni a szemhéjemelő izom (levator) – veleszületett szemhéjcsüngés korrekciója céljából végzett – kötőhártya felőli redőzésének eredményeit retrospektív módszerrel. Módszer: 20 beteg 22 szemhéján végeztük el a műtétet (átlagéletkor: 19,4 ± 9,9 év, férfi: 12 [60%], nő: 8 [40%]). Beválasztási kritérium volt a közepes (5–8 mm) vagy jó (9 mm felett) levatorfunkció. Kizártuk a korábban szemhéjkorrekciós műtéten átesett és a 3 hónapnál rövidebb követési idővel rendelkező betegeket. A műtét előtt megmértük a levatorfunkciót és a margó–reflex-távolságot. A műtét után megmértük a margó–reflex-távolságot, a szemhéjak magassága közti aszimmetria mértékét, és elemeztük a szemhéj posztoperatív kontúrját. Eredmények: A preoperatív levatorfunkció 10,6 ± 3,0 mm, a preoperatív margó–reflex-távolság 1,8 ± 0,8 mm volt. A 7,8 ± 7,2 hónap átlagos követési idő alatt a posztoperatív margó–reflex-távolság 3,2 ± 0,8 mm volt. A preoperatív és a posztoperatív margó–reflex-távolság különbsége nem tért el szignifikánsan a sikeres és a sikertelen műtétek között (p = 0,523). A szemhéjak magassága közti aszimmetria mértéke 3 betegnél haladta meg az 1 mm-t. A szemhéj posztoperatív kontúrja minden esetben megfelelő volt. A műtét összességében 86,4%-ban (19/22) volt sikeres. A helyi érzéstelenítésben és altatásban végzett műtétek közt nem találtunk szignifikáns különbséget a sikeresség tekintetében (p = 0,227). Következtetés: Tanulmányunk alapján az elvégzett műtéteink eredményessége a nemzetközi irodalomban közöltekhez hasonló volt. A veleszületett szemhéjcsüngés korrekciójára a kötőhártya felőli levatorredőzés megfelelő kezelési mód közepes vagy annál jobb levatorfunkció esetén. Orv Hetil. 2021; 162(18): 705–711. Summary. Introduction: Droopy eyelid (ptosis or blepharoptosis) is defined through abnormally low upper eyelid position. Ptosis can be classified as congenital or acquired. Objective: Our purpose was to report the results of posterior approach levator plication for congenital ptosis in a retrospective review. Method: 22 eyelids of 20 patients were included in this study (age: 19.4 ± 9.9 years, male: 12 [60%], female: 8 [40%]). The inclusion criteria were moderate (5–8 mm) or good (more than 9 mm) levator function. Patients with postoperative follow-up time shorter than 3 months and those who underwent previous eyelid surgery were excluded. The data collected included preoperative levator function and margin reflex distance, postoperative margin reflex distance, inter-eyelid height asymmetry and postoperative eyelid contour. Results: Preoperative levator function was 10.6 ± 3.0 mm, preoperative margin reflex distance was 1.8 ± 0.8 mm. During 7.8 ± 7.2 months postoperative follow-up, postoperative margin reflex distance was 3.2 ± 0.8 mm. The difference between preoperative and postoperative margin reflex distance was not significant (p = 0.523) in the group of successful operations compared with unsuccessful operations. Inter-eyelid height asymmetry was more than 1 mm in 3 cases. Satisfactory postoperative eyelid contour was achieved in all cases. Overall success rate was 86.4% (19/22). Surgical success did not differ significantly between surgeries in local or general anaesthesia (p = 0.227). Conclusion: Our study shows an overall success rate of the procedures comparable to those in international publications. Posterior approach levator plication for congenital ptosis with moderate or better levator function seems to be a suitable treatment method. Orv Hetil. 2021; 162(18): 705–711.

Background: Classic Kaposi sarcoma usually remains on the skin and has a slow progression; thus, local treatment methods are preferable. Imiquimod is an immunomodulatory agent with antiviral, antitumoural, and antiangiogenic properties that is expedient against Kaposi sarcoma. Objectives: We aimed to clarify whether imiquimod is effective on classic Kaposi sarcoma lesions by comparing imiquimod treatment with cryotherapy, which is the most-used treatment method in our department for this disease. Method: Patients with classic Kaposi sarcoma were included. All lesions of each patient were evaluated and measured by the blinded investigator considering infiltration and surface diameters. Then, lesions were categorized into 2 groups by the other investigator (nonblinded), and imiquimod 5% cream was administered 3 times per week without occlusion in 1 group. Cryotherapy was performed every 3 weeks in the other group. All lesions were reevaluated and measured at the end of 12 weeks by the blinded investigator. Initial and last measurements were compared between the treatment methods. Results: Fifty lesions of 8 patients were included in this study. Imiquimod and cryotherapy were applied to 26 and 24 lesions, respectively. At the end of the study, statistically significant decreases were detected in all scores between weeks 0 and 12 with both treatment methods. Mean percentages of change in scores were not significantly different between the methods. Conclusions: Based on a limited number of patients and lesions treated, we believe imiquimod may be a suitable option to use for the treatment of classic Kaposi sarcoma.

This investigation compared the effectiveness of two language treatment methods, modeling versus modeling plus evoked production, in promoting productive vocabulary in three toddlers identified as late talkers. A single-subject alternating treatments design was employed in this study in which different sets of words were taught under the two treatment methods during group and individual instruction. Some evidence of differential patterns of response to the treatment types was found for two subjects, but the subjects differed as to which particular treatment method was associated with better performance. Neither treatment method was effective for the third subject. Dynamic assessment measures were only marginally useful in predicting overall lexical learning potential in these subjects, and did not predict response to the two teaching methods. Implications of these results are discussed with regard to the role of language intervention for late talkers.

Purpose. To evaluate the clinical efficacy of prodom in the administration of urokinase in the vagina in couples with impaired semen liquefaction. Materials and Methods. Overall, 261 patients with impaired semen liquefaction were randomly divided into prodom-assisted urokinase treatment (PAUT) group ( n = 91 ), syringe-assisted urokinase treatment (SAUT) group ( n = 86 ), and traditional treatment (TT) group ( n = 84 ) in the first stage. If the first stage of treatment failed, other treatment methods were initiated instead and the patients were grouped according to the newer treatment method in the second stage. The pregnancy rate, time-to-conception, and treatment costs were evaluated in each group. Results. In the first stage, the pregnancy rate in the PAUT, SAUT, and TT groups was 69.23%, 29.07%, and 22.62%, respectively; the time-to-conception was 2.66 ± 1.44 , 3.69 ± 2.61 , and 3.86 ± 3.00 months, respectively; the treatment costs were 658.18 ± 398.40 , 666.67 ± 507.50 , and 680.56 ± 480.94 $, respectively. The pregnancy rate and time-to-conception were different in the PAUT group compared with those in SAUT and TT groups (all P < 0.05 ). However, the difference in treatment costs was not significant ( P = 0.717 ). In the second stage, 154 nonpregnant patients were divided into nine treatment groups, and the effects of changing TT to PAUT on the pregnancy rate, time-to-conception, and treatment costs were observed to be different from those of other treatments (all P < 0.05 ). Conclusion. Prodom-assisted urokinase can effectively treat male infertility secondary to impaired semen liquefaction.

`Valencia' and navel orange (C. sinensis L. Osbeck) fruit quality was evaluated following exposure to either a cold treatment (21 days below 2.2 °C) or a high-temperature forced-air (HTFA) treatment (ramped: fruit center end point, 47.2 °C; and constant: 46 °C for 310 min). These treatments are approved as disinfestation measures against selected fruit flies (APHIS, 1996). Fruits were stored at either 5 or 1 °C (cold treatment) for 14 days followed by 10 days at 11 °C and 7 days at 20 °C. Fruits were obtained six times during the commercial `Valencia' and navel orange season (three grower lots/time). Fruits exposed to HTFA (ramped and constant) treatments had significantly lower appearance ratings, total soluble solids, titratable acidity as compared to control or cold treated fruits. Cold treated fruits had significantly higher L* values. Fruits were also presented to an untrained sensory evaluation panel. Both ramped and constant temperature treated fruits were rated significantly inferior in taste. Although statistically significant, these differences were slight. This research demonstrates the potential deleterious quality attributes of `Valencia' and navel oranges due to HTFA; however, we believe that cold treatment may be the efficacious quarantine treatment method for distant export market. The potential for HTFA treatments for CA citrus, in light of these results is discussed.

Introduction. Epistaxis is one of the most common emergencies in Otorhinolaryngology. It is usually managed with simple conservative measures but occasionally it is a life threatening condition. Identification of the cause is important, as it reflects the management plan being followed.Aims and Objectives. To analyze the etiology and treatment methods for patients with epistaxis.Methods. A retrospective study was done in a tertiary care hospital in central Nepal. The study period was from May 2014 to April 2015.Results. A total of 84 patients had epistaxis; 52 were males and 32 were females. The most common cause of epistaxis was idiopathic (38.09%) followed by hypertension (27.38%), trauma (15.47%), and coagulopathy (8.33%). Regarding treatment methods, most (52.38%) of our patients required anterior nasal packing. Chemical cautery was sufficient to stop bleeding in 14.28% of patients while electrocautery and posterior nasal packing were performed in 2.38% and 16.66% patients, respectively. Two (2.38%) patients required endoscopic sphenopalatine arterial ligation.Conclusion. Hypertension, trauma and coagulopathy were the most common etiological factors among the patients in whom etiology was found although in most of the patients etiology could not be found. Anterior nasal packing was the most common treatment method applied to these patients.
