Sprungleistung der 7-jƤhrigen AnfƤngerinnenin rhythmischer Gymnastik ist stark von dem Zustandderen motorischen FƤhigkeiten beeinflusst
The aim of this study was to establish the probable influence of the characteristic motor ability and skill factors on the jumping/leaping performance in a sample of 55 novice female gymnasts (mean age 7.1 Ā± 0.3 years), who had participated in a year of training. The sample of variables consisted of 12 tests of the basic motor abilities and 9 RG (rhythmic gymnastics) specific leaping performance tests, in which 5 experienced RG-judges evaluated their performance. Canonical correlation analysis was utilized to establish the relations between the scores of the motor tests and the leaping/jumping performance marks. According to the linear correlation and canonical correlation results, coordination (coordination in rhythm, primarily) and strength (leg power, in the first place), contributed mostly to the performance evaluation marks assigned for the RG leaping elements (65% variance explained). Although being expected, the influence of flexibility on the leaping performance of novices in RG was not evident.Uvod Skokovi su osnovna skupina elemenata tijelom u ritmiÄkoj gimnastici. Može se pretpostaviti da je dobro izvoÄenje skokova na svim težinskim razinama preduvjet za postizanje dobrih rezultata ritmiÄarki. Ackerman (1988) pretpostavlja da su opÄe motoriÄke sposobnosti presudne za izvedbu skokova na prvom stupnju usvajanja znanja iz ritmiÄke gimnastike (RG). Osnovni cilj ovog istraživanja je kanoniÄkom korelacijskom analizom utvrditi utjecaj motoriÄkih sposobnosti na uspjeh u izvoÄenju skokova kod poÄetnica u RG. Metode Istraživanje je provedeno na uzorku od 55 sedmogodiÅ”njih poÄetnica u ritmiÄkoj gimnastici (prva godina vježbanja). Primijenjeno je 12 motoriÄkih testova koji pokrivaju podruÄje latentnih kretnih i energetskih dimenzija za koje se pretpostavlja da su nazoÄne i u ritmiÄkoj gimnastici. Odabrani su sljedeÄi motoriÄki testovi: (1) poligon natraÅ”ke; (2) koraci u stranu; (3) taping rukom; (4) taping nogom; (5) skok u vis - Sargent; (6) bacanje medicinke iz ležanja; (7) broj podizanja trupa iz ležanja na leÄima u minuti; (8) broj ÄuÄnjeva u minuti; (9) pretklon raznožno; (10) visoko prednoženje desnom nogom iz ležanja (mjereno u stupnjevima); (11) visoko prednoženje lijevom nogom iz ležanja (mjereno u stupnjevima) i (12) ritmiÄko bubnjanje. Za procjenu izvedbe skokova u ritmiÄkoj gimnastici odabrano je devet skokova bez sprave i sa spravom (težine razine A prema bodovnom pravilniku iz 2001. g.), primjerenih za poÄetnice u ritmiÄkoj gimnastici: (1) kozaÄki skok (bez sprave); (2) jelenji skok (bez sprave); (3) daleko-visoki skok (bez sprave); (4) trÄeÄi koraci i skok Å”kare kroz otvorenu vijaÄu okretanjem naprijed; (5) kruženje presavijenom vijaÄom u jednoj ruci, (6) kozaÄki skok; bacanje i hvatanje lopte, (7) jelenji skok - prolaz kroz obruÄ, (8) kozaÄki skok i kruženje Äunjevima, (9) jelenji skok, kruženje trakom i daleko-visoki skok. Uspjeh u izvoÄenju skokova procijenili su eksperti na temelju promatranja videozapisa. Pet sudaca neovisno je procjenjivalo uspjeÅ”-nost ritmiÄarki u svakom testu na Likertovoj ljestvici od pet stupnjeva. Povezanost motoriÄkih sposobnosti ritmiÄarki poÄetnica s uspjehom u izvoÄenju skokova utvrÄena je kanoniÄkom korelacijskom analizom. Rezultati, rasprava i zakljuÄak Svi primijenjeni testovi za procjenu uspjeÅ”nosti u izvoÄenju skokova sa spravama i bez njih imaju zadovoljavajuÄe vrijednosti objektivnosti (tablica 2), Å”to ukazuje na objektivno ocjenjivanje i slaganje sudaca. BuduÄi da su se provjeravala samo znanja osnovnih skokova (težina razine A) te osnovne tehnike spravama, možemo pretpostaviti da djevojÄice u poÄetnoj fazi uÄenja osnovnih elemenata iz ritmiÄke gimnastike najteže usvajaju daleko-visoki skok te skokove povezane s izbacivanjem sprave (lopte). Dobro izvoÄenje daleko-visokog skoka zahtijeva, osim eksplozivne snage, i najviÅ”i stupanj fleksibilnosti nogu, koja se kod poÄetnica joÅ” uvijek nije razvila do razine dostatne za kvalitetno izvoÄenje daleko-visokog skoka. KanoniÄkom korelacijskom analizom utvrÄena je povezanost izmeÄu rezultata motoriÄkih testova i izvoÄenja skokova u ritmiÄkoj gimnastici. Prema rezultatima linearne korelacijske i kanoniÄke korelacijske analize, koordinacija (osobito koordinacija u ritmu) te snaga (osobito eksplozivna snaga nogu) doprinose postizanju boljih rezultata u izvoÄenju skokova kod poÄetnica u ritmiÄkoj gimnastici. Premda je bio oÄekivan, utjecaj fleksibilnosti na skokove u ritmiÄkoj gimnastici nije utvrÄen. Prema predstavljenim rezultatima, sposobnost za motoriÄko uÄenje skokova u ritmiÄkoj gimnastici osobito je uvjetovana koordinacijom. Osim koordinacije, boljem izvoÄenju skokova doprinosi i eksplozivna snaga nogu. Autori pretpostavljaju da eksplozivna snaga nogu doprinosi izvoÄenju visokih skokova te tako omoguÄuje veÄu amplitudu pokreta.Die Absicht dieser Studie war, den wahrscheinlichen Einfluss von Faktoren der charakteristischen motorischen FƤhigkeit und Fertigkeit festzustellen auf die Sprungleistung von 55 AnfƤngerinnen in rhythmischen Gymnastik (das Durchschnittsalter 7,1 Ā± 0,3), die ein Jahr trainiert haben. Die Auswahl von Variablen umfasste 12 Tests der basischen motorischen FƤhigkeiten und 9 Tests der Sprungleistung, die fĆ¼r die rhythmische Gymnastik spezifisch sind, bei denen 5 erfahrene Schiedsrichter die Leistungen bewerteten. Die Analyse der kanonischen Korrelation wurde gemacht, um den Zusammenhang zwischen den Ergebnissen der motorischen Tests und den Noten fĆ¼r die gymnastische AusfĆ¼hrung festzustellen. Die Ergebnisse der linearen und kanonischen Korrelation zeigten, dass die Koordination (insbesondere die rhythmische Koordination) und die Kraft (in erster Linie die Beinkraft) die Noten fĆ¼r die Sprungelemente der rhythmischen Gymnastik beeinflussen, was den 65% des Unterschieds erklƤrt. Obwohl erwartet, war der Einfluss der FlexibilitƤt auf die Sprungleistung der Turnerinnen nicht festzustellen
Modified Operative Technique for Involutional Lower Lid Entropion
The paper presents a modified operative technique for involutional lower lid entropion. The prospective noncomparative
study of 101 lower eyelids of 88 patients undergoing surgery for involutional lower lid entropion was conducted
in period from September 2005 until March 2012. Indication for the surgery was entropion, previously untreated, with
moderate to severe horizontal lid laxity and no clinically relevant medial and lateral canthal tendon laxity. The operative
technique is our modification of Quickert and Jones procedures. Photo was taken preoperatively and one month after
surgery. Clinical follow-up was at 7th postoperative day, one month and six months after surgery and in case of the recurrence.
Long-term follow-up was obtained via telephone interviews. There were 44 male (50%) and 44 female (50%) patients
included in the study. The age of patients was in average 73.27Ā±8.1 years (range 53ā90 years). Early postoperative
complication was localized lid swelling found in two patients starting 4ā6 weeks postoperatively at the area of absorbable
suture. It resolved spontaneously in two and three weeks respectively. There was recurrence of entropion in 11 eyelids
(10.89%) of 10 patients. The mean interval between primary surgery and the recurrence was 17.45Ā±14.84 months (range
4ā48 months). In these eyelids Jones procedure was performed. However in four eyelids of four patients from the recurrent
group an additional surgery needed to be performed after 6, 12, 12 and 17 months respectively. Our modification of
surgical treatment for involutional lower lid entropion was effective in 89.11% of eyelids. Complications of the procedure
were scarce
Investigation and verification of criminal aspects of doping as a crime in sport law
O dopingu kao kažnjivoj radnji postoje razliÄita teorijska stajaliÅ”ta i miÅ”ljenja. Jedni smatraju da se doping treba kažnjavati kaznenopravnim sankcijama, drugi da je dovoljna prekrÅ”ajnopravna, a treÄi stegovna sankcija, kako bi se postigla svrha kažnjavanja. U naÅ”em pravnom sustavu borba protiv dopinga evoluirala je tako da danas imamo samodoping kao stegovno djelo koje se kažnjava prema pravilima proisteklima iz Svjetskog antidoping kodeksa. S druge strane, zakonodavac propisuje neovlaÅ”tenu proizvodnju i promet tvari zabranjenih u sportu kao zasebno kazneno djelo delicta communia, za koje se kažnjava, inter alia, onaj koji omoguÄava i stavlja na raspolaganje zabranjene tvari sportaÅ”u ili koji drugoga navodi na troÅ”enje tih tvari, a to može biti i sam sportaÅ”. MeÄutim, borba protiv dopinga ne ukljuÄuje samo materijalnopravno normiranje nego, Å”toviÅ”e, pitanja naÄina dokazivanja, otkrivanja i procesuiranja moguÄih poÄinitelja. Stoga autori u ovom radu iznose procesnopravne odredbe kojima je regulirana borba protiv dopinga, Å”to ukazuje na distinkcije koje postoje u pogledu pojedinih poÄinitelja ovog kaznenog/stegovnog djela. Doping je opasnost modernog svijeta koji se sastoji u prijevarnom postupanju poÄinitelja uzimanjem zabranjenih tvari radi postizanja vrhunskih rezultata. Pored toga Å”to je nespojiv s etiÄkim naÄelima sporta, te Å”to se uzimanjem dopinga može naruÅ”iti zdravlje sportaÅ”a, doping predstavlja delikt koji je potrebno sankcionirati. Pri tome, ostvariti punitivnu svrhu a ne utjecati negativno na ugled sporta, izazov je koji je stavljen i pred zakonodavca i pred sustav sporta opÄenito. Stoga borba protiv dopinga mora obuhvaÄati sustavnu koordinaciju materijalnopravnih i postupovnih odredbi u cilju zaÅ”tite integriteta Äistog sporta.There are different theoretical views and opinions on doping as a punitive act. Some believe that doping should be punished by criminal sanctions, others that a misdemeanor law is sufficient, the and third is a disciplinary sanction, to achieve the purpose of punishment. In our legal system, the fight against doping has evolved so that today we have self-doping as a disciplinary offense punishable under the rules of the World Anti-Doping Code. On the other hand, the legislator prescribes the unauthorized production and marketing of substances banned in sport as a separate offense of delicta communia, punishable, inter alia, by one who, permits and makes prohibited substances available to the athlete or who induces another to consume those substances, which may be himself athlete. However, the fight against doping involves not only substantive legal standardization but, moreover, questions of how to prove, detect and prosecute possible perpetrators. Therefore, the authors of this paper present procedural provisions governing the fight against doping, which points to the differences that exist with respect to the perpetrators of this criminal / disciplinary offense. Doping is a danger in the modern world, consisting in the fraudulent treatment of perpetrators by taking illicit substances in order to achieve superior results. In addition to being incompatible with the ethical principles of sport, and doping can impair the health of athletes, doping is a tort that needs to be sanctioned. In doing so, to pursue a punitive purpose and not adversely affect the reputation of sport is a challenge that has been put before both the legislature and the sport system in general. Therefore, the fight against doping must include the systematic coordination of substantive and procedural provisions in order to safeguard the integrity of pure sport
Patient with Lingual Thyroid and Squamous Cell Carcinoma of the Tongue Base ā Case Report
We demonstrate a rare case of lingual thyroid together with squamous cell carcinoma of the base of tongue. 54-year old patient presented with left sided lymph node enlargement in regions II, III and IV, without any clinical symptoms. Physical examination revealed semicircular bulge at the base of tongue measuring 30x20 mm and tumorous lesion was suspected. Neck ultrasound showed pathological enlargement of lymph nodes and FNA of lymph node revealed squamous carcinoma cells in the smear. Further investigation included CT and MRI of the neck depicted ectopic thyroid tissue in base of tongue and enlarged and necrotic lymph nodes in regions II and III. Primary carcinoma could not be depicted. Biopsy of the lingual mass was performed and histology confirmed ectopic thyroid tissue. Physical examination of the oral cavity was repeated and suspicious area on the left side of the tongue base near ectopic thyroidal tissue was identified. Histology after biopsy confirmed squamous cell carcinoma with superficial growth. This case emphasizes the important role that collaboration of radiologist and otorhinolaryngologyst has in correctly diagnosing oropharyngeal
pathology. Also, we underline the importance of careful oropharyngeal region screening in case of unknown pathologic
lymphadenopathy, when the possibility of oropharyngeal cancer has to be considered
Concordance of estimated residual tumor size by magnetic resonance imaging and pathohistologic findings in breast cancer patients after neoadjuvant chemotherapy
Cilj. Cilj istraživanja je procijeniti podudarnost veliÄine rezidualnog tumora, izmjerene magnetskom rezonancijom (MR) i patohistoloÅ”kom dijagnostikom (PHD) u pacijentica s karcinomom dojke nakon provedene neoadjuvantne kemoterapije (NAK) te procijeniti moguÄi utjecaj ypT stadija tumora na nepodudarnost veliÄina izmjerenih navedenim metodama. Ispitanici i metode: U retrospektivno istraživanje ukljuÄeno je 50 pacijentica. UkljuÄni kriterij su pacijentice kod kojih je uÄinjen operativni zahvat uz prethodno proveden NAK karcinoma dojke, na Å”to je odgovor praÄen s najmanje dva MR pregleda. VeliÄina tumora na MR-u usporeÄena je s veliÄinom na PHD-u (zlatni standard) pomoÄu regresijske analize Passing-Bablok te je izraÄunat njihov koeficijent korelacije. Analizirana su sva odstupanja i podudarnosti veliÄine, kao i eventualni utjecaj ypT stadija tumora na razliku izmeÄu dviju metoda. Razlika od Ā± 0,5 cm u veliÄini tumora procijenjenih slikovnom metodom i u PHD nalazu smatrale su se podudarnima veliÄinama. Rezultati: Srednja vrijednost veliÄine rezidualnog tumora na MR-u iznosila je 19,1 Ā± 17,71 mm, dok je na PHD-u iznosila 16,87 Ā± 18,19 mm. IzraÄunati r koeficijent korelacije iznosi 0.64 (p < 0.001). Provedenom analizom potvrÄeno je da nema znaÄajne razlike izmjerenih veliÄina tumora na MR-u i PHD-u (p = 0.552) te se metode mogu smatrati podudarnima. Nije uoÄena statistiÄki znaÄajna razlika u ovisnosti o ypT stadiju tumora koja bi utjecala na nepodudarnost veliÄina. ZakljuÄci: MeÄu dvjema metodama nema konstantnog niti proporcionalnog odstupanja u mjerenjima te se metode mogu smatrati podudarnim. MR dojke je dobra metoda za procjenu veliÄine rezidualnog tumora dojke kod pacijentica koje su podvrgnute neoadjuvantnoj kemoterapiji usporedno s PHD-om (zlatni standard).Aim: The goal of this study is to evaluate the concordance between residual tumour size measured on magnetic resonance imaging (MRI) and pathohistological findings in patients who underwent neoadjuvant chemotherapy and operative procedure, and if any pathohistological features may affect that agreement. Respondents and methods: Fifty patients with breast cancer were retrospectively evaluated. Patients who underwent neoadjuvant chemotherapy before the operative procedure, and were assessed with at least two MRI examinations, where included in this study. The primary tumour size measured by MRI was compared with pathohistological findings, which was considered as the gold standard. All differences and size correspondence were analyzed as well as the possible influence of ypT stage of tumour between the two methods. Results: The mean value of residual tumour size on MRI was 19,2 Ā± 17,71 mm, while on pathohistological findings it was 16,87 Ā± 18,29 mm. A calculated correlation coefficient between the two methods was 0.64 (p < 0.001). There was no statistically significant difference between two methods for measuring residual tumour size (p = 0.552), as well as a statistically significant influence of ypT stage on measuring, so these methods may be considered to be concordant. Conclusions: There is neither a constant nor a proportional deviation in the measurements between the two methods, so these methods can be considered concordant. Breast MRI is a reliable method for estimating residual tumour size in patients undergoing neoadjuvant chemotherapy in comparison to pathology
