Full textAbstract:
Viene analizzato il ruolo della neuroradiologia nello studio del deterioramento mentale ed inoltre vengono descritti i quadri TC in alcune malattie degenerative encefaliche. L'invecchiamento cerebrale si accompagna alla TC a dilatazione progressiva del III ventricolo e di quelli laterali ed, in minor modo, ad allargamento dei solchi corticali e della parte anteriore della scissura di Silvio. Appare inoltre diminuito il coefficiente di attenuazione della sostanza bianca. Col progredire dell'età si ha cioè un quadro TC di atrofia prevalentemente sottocorticale che è via via più evidente dai 50–60 anni in poi. Tale atrofia «fisiologica» può essere difficilmente differenziabile da quella patologica. Infatti, le demenze sono caratterizzate, almeno nelle fasi iniziali, da quadri TC ed RM del tutto sovrapponibili a quelli che si hanno nel normale processo d'invecchiamento. Per tentare di risolvere questo problema vari autori si sono cimentati nella ricerca di metodiche di misurazione e si sono impegnati nel definire il range di normalità délle dimensioni cerebrali. Le misurazioni attualmente usate sono divisibili in lineari, planimetriche, volumetriche e densitometriche. Quelle volumetriche appaiono oggi preferibili rispetto agli altri tipi in quanto sono tridimensionali e quindi più veritiere. Esse abbisognano però di particolari programmi di calcolo computerizzati non sempre disponibili. Per alcuni autori l'utilità délle misurazioni di atrofia cerebrale appare indubbia e necessaria nel tentare di distinguere la normalità dalla patologia. Per evitare falsi negativi è comunque consigliata la ripetizione dell'esame dopo un intervallo relativamente breve di tempo. Infatti, in caso di atrofia patologica vi sarà un'accentuazione délle dimensioni ventricolari nettamente maggiore rispetto a quella che ci si aspetterebbe in un soggetto sano délla stessa età in cui le variazioni, nello stesso periodo, sono nulle o minime. Altri autori negano invece un'effettiva utilità nel misurare l'atrofia cerebrale. Infatti, si è riscontrata sovrapposizione compléta o quasi fra la definizione soggettiva ( «ad occhio») di atrofia cerebrale patologica e quella obiettiva conseguente a tecniche sofisticate di misurazione delle dimensioni delle varie componenti cerebrali. Inoltre, alcuni sostengono che la diagnosi di demenza deve essere sempre e comunque clinica e che le indagini neuroradiologiche possono essere solo un ausilio. Infatti, le correlazioni fra atrofia cerebrale e misurazioni psicometriche sono, nei vari studi, deboli o del tutto inesistenti. A questo proposito vi sono esempi di pazienti affetti da demenza che presentano alla TC sistema ventricolare e solchi di dimensioni normali ed esempi di persone normali con ventricoli e solchi dilatati.

Objective: To determine the prevalence of short gastrocnemius in orthopaedic patients treated in the emergency room and the foot and ankle outpatient clinic of a public hospital and to evaluate the relationship between prevalence and certain specific symptoms. Methods: This was an observational cross-sectional study conducted using a questionnaire completed by patients treated in February 2018. Results: Of the 160 patients studied, 21 (13.1%) had a diagnosis of shortening of the gastrocnemius. The condition was more prevalent in females than in males, with no differences in race, age, laterality or occupation. The most commonly associated symptoms were calf pain, back pain, equinism and metatarsalgia, which were all present in more than 2/3 of cases. Conclusion: Shortening of the gastrocnemius is a fairly common pathology that deserves greater attention in orthopaedic practice. Additional studies are needed to better correlate epidemiological findings with this pathology. Level of Evidence II; Diagnostics Studies.

Full textAbstract:
Wave disturbances to baroclinic flows produce cyclones in the atmosphere and eddies in the oceans and have been extensively studied in laboratory experiments with differentially heated annuli of rotating fluid. Related analytical studies have concentrated mainly on the development of slowly growing waves on laterally uniform zonal flows. Neutral inviscid waves on such flows do not advect their own potential vorticity field whereas neutral waves on most laterally sheared baroclinic flows do. Scaling arguments suggest that on these laterally sheared flows the harmonics generated by the neutral waves play the dominant role in arresting the initial growth of weakly unstable waves. The arrest of a wave is chiefly accomplished by fully nonlinear advection within a critical layer centred on the wave's steering level whose depth is proportional to the wave's amplitude. Explicit numerical solutions illustrating these points are presented for a case in which the critical level is non-singular and the inviscid calculations comparatively straightforward. The stability of the solutions and the effects of diffusive fluxes on them are discussed. Potential vorticity diagnostics for a numerical simulation of a wave flow in a rotating annulus near the axisymmetric transition show that distortion of the wave's potential vorticity field is mainly confined to the vicinity of the steering level. Assumptions and approximations made in the explicit calculations which are of doubtful validity for this flow are highlighted.

Background: Secondary tumors of the ovary (STOs) account for 10–25% of all ovarian malignancies, including metastases from primary gynecological tumors. Colorectal cancer (CRC) has been recognized as one of the most common causes of STOs in Western countries. Despite it being well-known that CRC originating from the right versus left side of the colon/rectum differ substantially, there is a paucity of information regarding the effect of the primary tumor sidedness on the clinicopathological characteristics of STOs. Methods: This retrospective, observational chart review study included patients with histologically confirmed STOs of CRC origin diagnosed between January 2000 and December 2019. The clinicopathological characteristics of STOs originating from left-sided and right-sided CRC were compared. Univariable and multivariable analyses employing elastic net Cox proportional hazard models were used to evaluate potential prognostic factors. Further, the role of imaging methods in STOs diagnostics was evaluated. Results: Fifty-one patients with STOs of colorectal origin were identified. The primary tumor originated in the right and left colon/rectum in 39% and 61% of the cases, respectively. STOs originating from right-sided primary tumors were more frequently bilateral, associated with peritoneal carcinomatosis, had the ovarian surface affected by the tumor, and contained a mucinous component. The independent prognostic factors for overall survival in the whole cohort included: the presence of macroscopic residual disease after cytoreductive surgery, menopausal status, the application of systemic therapy, and the application of targeted therapy. In 54% of cases, the imaging methods failed to determine the laterality of the STOs correctly as compared to pathological reports and/or intraoperative findings. Conclusion: STOs originating from left-sided and right-sided CRC show distinct clinicopathological characteristics. Moreover, different metastatic pathways might be employed according to the primary tumor sidedness. Considering the discrepancies between radiological assessment and histopathological findings regarding the laterality of STOs, bilateral adnexectomy should be advised whenever feasible.

Full textAbstract:
I prelievi venosi dai seni petrosi inferiori sono utilizzati nella diagnostica differenziale della sindrome di Cushing per dimostrare l'origine ipofisaria o ectopica dell'ipersecrezione di ACTH. Il drenaggio venoso dell'adenoipofisi avviene attraverso due plessi venosi, il destro ed il sinistro, che coprono la superficie della ghiandola e scaricano nel seno cavernoso omolaterale, direttamente o attraverso i seni intercavernosi. I seni petrosi inferiori rappresentano le principali vie di deflusso dei seni cavernosi; essi sono cateterizzabili con relativa facilità, allo scopo di eseguire prelievi peril dosaggio degli ormoni ipofisari. La nostra tecnica prevede il cateterismo per via transfemorale; utilizziamo cateteri da 4 o 5 French, retti, con estremo distale ricurvo a 45°, senza fori laterali. Sono indispensabili accurati controlli flebografici per dimostrare l'esatta posizione dei cateteri prima dell'esecuzione dei prelievi. In letteratura viene riportata un'alta accuratezza diagnostica dei prelievi dai seni petrosi nella diagnosi differenziale tra malattia di Cushing e sindrome da ACTH ectopico, mentre assai minore è la specificità di una corretta localizzazione delle lesioni ipofisarie. Riteniamo che gli errori di lateralizzazione possano essere so1tanto ridotti, ma non eliminati da una corretta esecuzione dell'indagine: infatti dipendono da variabilità anatomiche, dalla sede dell'adenoma e, verosimilmente, da asimmetrie di flusso attraverso le vene di drenaggio ipofisario.

Full textAbstract:
The purpose of this case report was to describe the surgical correction of a cholecystocutaneous fistula in a dog. A 6 yr old vizsla presented with a 2 mo history of a chronic draining wound on the right ventral thorax. Diagnostics revealed numerous fistulous tracts opening at a single site on the right ventrolateral chest wall, extending caudodorsally through the chest wall and diaphragm to the region of the right medial liver lobe. Exploratory laparotomy revealed the apex of the gallbladder adhered to the diaphragm with a tract of fibrous tissue extending along the diaphragm laterally to the right thoracic wall. Cholecystectomy was performed. The fistulous tract was incised to expose the lumen of the fistula, and the fistula was omentalized. Twenty-eight months after surgery, the dog had had no recurrence of the fistulous tract. Exploratory laparotomy allowed excellent visualization of the intra-abdominal path of the fistula and facilitated the ease of resection of the source. Cholecystectomy resulted in rapid and complete resolution of the fistula without the need for excision of the fistula. Although rare, gallbladder disease should be a differential for chronic fistulous tracts.

Full textAbstract:
The paper discusses dynamic effects occurring in machinery rotors supported in bearings and pedestals with laterally different characteristics. In the considered rotor model the anisotropy of radial stiffness and tangential (“cross”) stiffness components are included. Within certain ranges of the rotative speed the support anisotropy leads to the specific, excited-by-unbalance rotor lateral synchronous vibrations in a form of backward (reverse) precession. In addition, one section of the rotor may precess backward, while the other section simultaneously precesses forward. Experimental results illustrate this phenomenon. The analytical model of the system is based on multimode modal approach. It is also shown in this paper that greatly enhanced information for machine malfunction diagnostics can be obtained by simulated rotation of the XY transducer system observing rotor lateral vibration. This simulated rotation can be accomplished by the machine diagnostic data acquistion and processing system. The data processing also includes extraction of forward and backward components of elliptical orbits filtered to one frequency, and the filtered orbit major axis magnitude and its angular orientation.Numerical examples, field data, and experimental results performed on a rotor rig illustrate applications.

ZusammenfassungIm Rahmen eines Konsensusprozesses der Arbeitsgruppe „subaxiale HWS-Verletzungen“ der Sektion Wirbelsäule der DGOU erfolgte in 4 Sitzungen im Jahre 2016 die Erstellung der vorliegenden Therapieempfehlungen unter Berücksichtigung der vorhandenen Literatur. Therapieziele sind eine dauerhaft stabile, schmerzfreie Halswirbelsäule und der Schutz vor sekundären neurologischen Schäden unter größtmöglicher Berücksichtigung der Beweglichkeit und des Wirbelsäulenprofils. Aufgrund der Praktikabilität und der guten Evaluation hinsichtlich Reliabilität sollte die AOSpine-Klassifikation für subaxiale HWS-Verletzungen für die Klassifikation zur Anwendung kommen. Es wird die Canadian C-Spine Rule als klinischer Algorithmus zur Entscheidung hinsichtlich der Notwendigkeit einer bildgebenden Diagnostik empfohlen. Bei gemäß dieser Regel anamnestisch oder klinisch hohem Verdacht auf eine strukturelle, instabile Verletzung ist die Spiral-CT der HWS Verfahren der Wahl. Die konventionelle Röntgendiagnostik in 2 Ebenen bleibt Fällen vorbehalten, in denen kein „gefährlicher Unfallmechanismus“ vorliegt. Die Indikation für die MRT der HWS wird vor allem bei nicht erklärbaren neurologischen Symptomen, bei geplanter geschlossener Reposition und dorsaler Stabilisierung und zum Ausschluss vermuteter diskoligamentärer Verletzungen empfohlen, wobei hier je nach Befundkonstellation eine abgestufte Dringlichkeit gilt. Die CT-Angiografie wird bei höhergradigen Facettengelenkverletzungen oder bei Vorliegen vertebrobasilärer Symptome empfohlen. Die konventionelle Funktionsdiagnostik wird ausschließlich in Form der ärztlich geführten dynamischen Bildwandlerdurchleuchtung bei persistierendem Verdacht auf eine instabile Verletzung empfohlen. Die therapeutische Strategie richtet sich primär nach der Verletzungsmorphologie, die in der AOSpine-Klassifikation beschrieben wird. A0-Frakturen sollten konservativ behandelt werden. A1- und A2-Frakturen sollten meistens konservativ behandelt werden, wobei die segmentale Kyphose in Einzelfällen eine OP-Indikation bedingen kann. A3-Frakturen stellen in den meisten Fällen eine OP-Indikation dar, in Einzelfällen ist eine konservative Behandlung möglich. A4-Frakturen sowie die B- und C-Verletzungen bedürfen einer operativen Therapie. Die ventrale Plattenspondylodese mit interkorporeller Abstützung (bei Berstungskomponente durch Korporektomie und Wirbelkörperersatz) wird für die meisten Verletzungen empfohlen, eine rein dorsale oder zusätzlich dorsale Stabilisierung kann bei besonderer Befundkonstellation möglich oder sogar notwendig sein. In diesen Fällen ist die Instrumentierung mit Massa-lateralis-Schrauben zumeist ausreichend; bei Anwendung von Pedikelschrauben in Höhe C III – C VI wird ein Navigationssystem empfohlen. Bei Vorliegen einer ankylosierenden Grunderkrankung (M3-Modifikator) wird hingegen die dorsale, langstreckige Stabilisierung favorisiert.

Full textAbstract:
In May 2005, an estimated 10 to 15% mortality of various cultivars of false cypress (also named Lawson cypress or Port-Orford-cedar [Chamaecyparis lawsoniana]) with severe wilt was observed in field stands of an ornamental nursery in western Hungary. Wilted plants had rot-associated reduction of their root system. Root discoloration and occasional chlorosis of lower leaves commenced on potted 3-year-old plants that were held in the open air for 10 to 12 months before planting. Four species of Phytophthora (P. lateralis, P. eriugena, P. hibernalis, and P. cinnamomi) have been reported on this host (2). Direct plating of discolored roots from the most susceptible cultivar (Silver Globus) onto a selective potato dextrose agar or carrot agar medium yielded pure cultures that developed white, stellate colonies with sparse aerial mycelia. The hyphal growth was optimal at 25°C, but the growth above 32°C and below 4°C was completely inhibited. Single, terminal sporangia on simple (occasionally sympodial) sporangiophores formed abundantly in nonsterile soil filtrate but not in agar. Sporangia, 31 to 67 μm (59.1 ± 9.3 μm) long and 25 to 39 μm (31.5 ± 4.0 μm) wide, were noncaducous and semipapillate, variable in shape, mostly obpyriform, rarely obovoid, ovoid-ellipsoid and spherical or bifurcated and distorted, and the exit pore was narrow (7.2 ± 0.8 μm). No external or internal proliferation and no hyphal swellings or chlamydospores were observed. The isolates were homothallic with smooth-walled oogonia (27.3 ± 3.4 μm in diameter) and paragynous antheridia. The oospores (24.7 ± 2.1 μm in diameter) were plerotic. The morpho-physiological features suggested that our isolates belonged to Waterhouse's Group III, and in particular, represented P. citricola. This was confirmed by cellulose acetate electrophoresis of malate dehydrogenase; the isozyme pattern of false cypress isolate was identical to that of the ITS-sequenced (NCBI Accession No. AY366193) P. citricola isolate from a Hungarian alder forest (1). Pathogenicity tests on four 3-year-old potted false cypress (cv. Silver Globus) plants in the greenhouse resulted in rapidly developing (within 2 weeks) sunken, necrotic lesions at the stem base around the site of wound inoculation with a 5-mm-diameter mycelial agar plug. After 12 weeks, each inoculated plant wilted and died. The causal agent was consistently reisolated from necrotic tissues. In Hungary, P. citricola was first isolated and identified from alder forest soil (1). Nonetheless that false cypress has been listed as the host of P. citricola in Norway and Poland (3,4), to our knowledge, this report is the first definitive description of this Phytophthora sp. on this host.

Full textAbstract:
Összefoglaló. Bevezetés: Az állcsonti cysták helytálló diagnosztikája a klinikai, radiológiai és patológiai leletek együttes értékelésével lehetséges. Korábbi munkánk során többször tapasztaltuk a klinikoradiopatológiai kommunikáció és korreláció hiányát, és ez olykor inadekvát diagnózisok felállításához vezetett. Célkitűzés: Célunk ezen kommunikációs probléma mértékének becslése és annak bemutatása, hogy ez a hiányosság hogyan befolyásolhatja a diagnosztikát. Módszer: Korábbi, más célú retrospektív elemzés újraértékelése történt a klinikai (radiológiai) adatközlés, a revízió kapcsán módosuló diagnózisok számszerűsítése céljából, valamint további 3 egyetemi patológiai intézet 10-10 anonimizált leletének vizsgálata az adatközlések vonatkozásában. Eredmények: 2 intézményben 85 odontogen cysta diagnózisakor csupán a betegek életkora, neme volt 100%-osan ismert. A lokalizációra vonatkozó adekvát információ 62%-ban, a méretre vonatkozó csupán 29%-ban fordult elő a szövettani kérőlapokon. Összességében a diagnózist segítő releváns információt csak 52%-ban adtak meg. Az utólagos klinikoradiopatológiai korrelációra törekvő revízió során 38/85 esetben (45%) módosult a végső diagnózis kisebb vagy nagyobb mértékben. A megküldött leletek alapján a klinikai/radiológiai adatok közlése <50% és 100% közöttinek becsülhető más intézetekben is. Az 5 intézmény közül csak az egyikben utalt specializációra az, hogy minden leletet egy patológus véleményezett, általában sok patológus (n = 25) valamelyike véleményezte a kevés tömlőt (n = 105). A diagnózis kommunikáció hiányán alapuló kisiklásának lehetőségét 5 példával illusztráljuk: cysta radicularisként leletezett paradentalis, lobos follicularis és lateralis periodontalis cysta, ductus nasopalatinus cysta és radicularis cysta differenciáldiagnosztikáját példázó tömlő, valamint botryoid odontogen cysta kerül bemutatásra. Következtetés: Az odontogen tömlők precíz diagnosztikája mind a klinikai, mind a patológiai oldalról javítást igényel, amelynek egyik része az ilyen irányú képzés lehet. Orv Hetil. 2021; 162(12): 458–467. Summary. Introduction: Proper diagnosis of jaw cysts requires the parallel evaluation of clinical, radiological and histopathological findings. Lack of clinico-radio-pathological correlation can lead to inconsistent diagnoses. Objective: To evaluate the rate of lacking clinico-pathological communication and demonstrate how this may influence diagnostics. Method: Data of a former retrospective analysis were re-evaluated to quantify the lack of clinical data communicated to pathologists and estimate the rate of final diagnoses requiring alteration after review of all available clinical data. 10 anonymized reports on odontogenic cysts from 3 university pathology departments each were analysed for the lack of relevant clinical information. Results: Only the age and gender of patients were documented in 100% for 85 jaw cysts diagnosed in 2 departments of pathology. Adequate information about cyst localization and size were communicated in 62% and 29%, respectively. Overall, information relevant to the diagnosis was given in 52% of the cases. Revision based on clinico-radio-pathological correlation led to alterations of the diagnosis in 38/85 cases (45%). Based on reports from other institutions, the communication of clinical data is estimated to be between <50% and 100%. 25 pathologists were involved in reporting 105 cysts. 5 cases illustrate how diagnosis may fail without good communication: a paradental, an inflamed dentigerous and a lateral periodontal cyst, each misdiagnosed as radicular cyst; a cyst raising the differential diagnosis of nasopalatine duct versus radicular cyst; a botryoid odontogenic cyst. Conclusion: Proper diagnosis of jaw cysts requires improvements from both pathological and clinical sides, and could probably be improved through education. Orv Hetil. 2021; 162(12): 458–467.

Abstract Primary hyperparathyroidism (PHPT) is an endocrine disease, the clinical picture of which has slowly shifted to milder and asymptomatic forms during the last decades. Objective to describe the clinical presentation and the main laboratory and imaging findings in a group of patients with PHPT diagnosed during the last 10 years. Materials and Methods This was a retrospective cross-sectional study with data review from the database of a tertiary endocrine clinic from the last 10 years. Secondary causes for elevated PTH were excluded. The major clinical symptoms and signs of hypercalcemia/HPT were reviewed as well as concomitant diseases and medications. Serum calcium (total, albumin-corrected and ionized; sCa, corrCa, iCa+), phosphates (P), magnesium, creatinine, alkaline phosphatase, beta-crosslinks were measured. The intact parathyroid hormone (iPTH) and 25(OH)-vitamin D were determined by electro-hemi-luminescence (Elecsys, Roche Diagnostics). 24-hour urinary probes for calcium and phosphate were collected. Neck ultrasound (US) was used as the localization study of choice. Almost half of the participants underwent fine-needle aspiration biopsy (FNAB) with cytology and needle-washouts for iPTH. One fourth of the patients were assessed by Single-Photon Emission Tomography (SPECT-CT). Data on bone density (from DXA), fractures and renal stones (from renal US) were collected. Results One hundred patients met the study criteria – 95 were women. Most of them were in their 5th and 6th decades. The median corrected sCa was 2.73 mmol/l, iCa+ – 1.39 mmol/l, P – 0.88 mmol/l, iPTH – 14.5 pmol/l and 25(OH)D – 54.0 nmol/l. Normal sCa was registered in 20 participants (20%), while normal sP – in 67.0%. The neck US located single lesions (parathyroid adenoma) in 81% – behind or below the left inferior pole of the thyroid gland in 33 cases (33%) and contra-laterally in another 33%. FNAB of the suspicious lesion had been performed in 51% of the study subjects. The cytology confirmed the presence of parathyroid cells in 22 cases (43.1%), Bethesda II thyroid nodules in 21 cases (41.2%), Bethesda III nodules in 2 cases (3.9%) and insufficient samples (Bethesda I) in 5 cases (9.8%). SPECT-CT from 27 patients identified a suspicious left parathyroid in 11 cases, a right one – in 6 cases, as well as three ectopic locations. BMD data were available in 66 female patients and showed a higher prevalence of osteoporosis than in the general age-matched population; fractures, however, were not more frequent. Data from renal ultrasound were available in 77% and revealed chronic pyelonephritis without stones in 8 patients and renal stone disease – in 37 patients. Conclusion To our knowledge, this study is the first of its kind in our country during the last two decades. Mild to moderate hypercalcemia was very common, although most patients were oligoor asymptomatic. Renal and bone involvement were surprisingly frequent, with reduced eGFR and low bone mass being more prevalent than in the general population. The most typical location was a single parathyroid lesion within the lower glands. The use of SPECT-CT seems to decline and is replaced by US-guided FNAB with needle washout measurements of iPTH and cytological examination. Although the general picture of PHPT is shifting towards milder and asymptomatic (and probably earlier) forms of the disease, the classical clinical presentation can still be found in everyday practice.

Skeletal muscle status and its dynamic follow up are of particular importance in the management of several diseases where weight and muscle mass loss and, consequently, immobilization occurs, as in cancer and its treatment, as well as in neurodegenerative disorders. But immobilization is not the direct result of body and muscle mass loss, but rather the loss of the maximal tension capabilities of the skeletal muscle. Therefore, the development of a non-invasive and real-time method which can measure muscle tension capabilities in immobile patients is highly anticipated. Our aim was to introduce and evaluate a special ultrasound measurement technique to estimate a maximal muscle tension characteristic which can be used in medicine and also in sports diagnostics. Therefore, we determined the relationship between the results of shear wave elastography measurements and the dynamometric data of individuals. The measurements were concluded on the m. vastus lateralis. Twelve healthy elite athletes took part in our preliminary proof of principle study—five endurance (S) and seven strength (F) athletes showing unambiguously different muscle composition features, nine healthy subjects (H) without prior sports background, and four cancer patients in treatment for a stage 3 brain tumor (T). Results showed a high correlation between the maximal dynamometric isometric torque (Mmax) and mean elasticity value (E) for the non-athletes [(H + T), (r = 0.795)] and for the athletes [(S + F), (r = 0.79)]. For the athletes (S + F), the rate of tension development at contraction (RTDk) and E correlation was also determined (r = 0.84, p < 0.05). Our measurements showed significantly greater E values for the strength athletes with fast muscle fiber dominance than endurance athletes with slow muscle fiber dominance (p < 0.05). Our findings suggest that shear wave ultrasound elastography is a promising method for estimating maximal muscle tension and, also, the human skeletal muscle fiber ratio. These results warrant further investigations with a larger number of individuals, both in medicine and in sports science.

REFERRAL PAIN DISTRIBUTION PATTERN AND TRIGGERING POSITION OF SACROILIAC JOINT PAINABSTRACTIntroduction: sacroiliac joint (sIJ) contribution to cause low back pain is still widely debated. sIJ is hardly distinguished from facet joint pain or other musculoskeletal disorder causing low back pain and leads to diagnostic difficulties. There are several factors that contribute to SIJ pain diagnosis, which are referral pain area and triggering position.Aim: To investigate the distribution pattern of referral pain and position that could trigger the sacroiliac joint pain.Method: Patients with complaints of pain in buttock area and diagnosed as sIJ pain by intra articular block diagnostic test at Neurology Clinic of of siloam Hospitals Lippo Village between August to december 2017 were interviewed to record the area of referral pain and position which triggered the pain.Results: 114 subjects with complaint of buttock pain, ratio between men and women was 1:2.35 (n=34 and 80), were included in this study. Posterior compartment of the thigh (19.3%, n=22) is the most common referral pain area followed by lateral part of the thigh (11.4%, n=13). Getting up from sitting position and long period of sitting were the two most dominant factors that could trigger pain (61.4%, n=70 and 49.1%, n=56).Discussion: The referral pain distribution pattern of sacroiliac joint pain was dominated by the posterior part and lateral part of thigh, while getting up from sitting and long period of sitting is found in majority of the subjects as the most dominant triggering position.Keywords: Pain pattern, sacroiliac joint pain, triggering positionABSTRAKPendahuluan: Kontribusi nyeri sendi sakroiliaka sebagai penyebab nyeri pinggang masih menjadi perdebatan. Secara klinis, nyeri sendi sakroiliaka sulit dibedakan dengan nyeri sendi faset lumbal maupun gangguan muskuloskeletal lainnya sehingga menyulitkan dalam diagnosis. Terdapat faktor yang memengaruhi terjadinya nyeri sendi sakroiliaka antara lain posisi tubuh yang mencetuskan nyeri dan area nyeri alih yang menyertainya.Tujuan: Untuk mengetahui pola distribusi nyeri alih dan faktor posisi tubuh yang mencetuskan atau memperberat nyeri sendi sakroiliaka.Metode: Pasien yang datang dengan keluhan nyeri bokong yang terdiagnosis mengalami nyeri sendi sakroiliaka berdasarkan tes diagnostik injeksi blok intraartikular di poliklinik saraf RS Siloam Lippo Village dalam rentang waktu Agustus–Desember 2017 dilakukan wawancara untuk mengetahui area nyeri alih dan posisi pencetus nyeri.Hasil: Sebanyak 114 pasien dengan keluhan pada area bokong, rasio antara laki-laki dan perempuan dengan perbandingan 1:2,35 (n=34 dan 80) diikutsertakan dalam studi ini. Paha bagian posterior merupakan area nyeri alih terbanyak (19,3%, n=22) diikuti area paha lateralis (11,4%, n=13). Sedangkan posisi tubuh yang paling dominan memicu timbulnya nyeri sendi sakroiliaka adalah posisi bangun dari duduk (61,4%, n=70) dan duduk lama (49,1%, n=56).Diskusi: Pola distribusi nyeri alih pada pasien nyeri sendi sakroiliaka yang paling banyak ditemukan adalah nyeri pada daerah paha sisi posterior dan paha sisi lateral sedangkan faktor yang paling dominan mencetuskan atau memperberat nyeri sendi sakroiliaka adalah posisi bangun dari duduk dan posisi duduk yang lama.Kata kunci: Nyeri sendi sakroiliaka, pola nyeri, posisi tubuh pencetus

Abstract The article presents the first record of the Hiplyra elegans crab — from the Leucosiidae family — on the Iraqi coast, located in the north-west Arabian Gulf - Iraq. Through the morphological characteristics of the species Hiplyra elegans, it was possible to diagnose these crabs. Such characteristics, used for classification, are: the lateral margin of the carapace posteriorly to subhepatic facet closely beaded; granules smaller posteriorly; frontal region distinctly narrowed; carapace is long thin wide; sixth somite of male abdomen smooth; elevated male telson on lateral portion; dactyl shorter than upper margin of propodus, sickle-shaped, with its inner margin smooth, Chela elongate, laterally flattened, dactyl with inner margin entire. In male surface minutely granulate, bearing perliform granules anteriorly; Lower margin of propodus granulate, line of minute granules on the inner lower surface, upper margin minutely granulates. Pereiopods slender, short. Pereiopodal meri longer than carpi and propodi; dactyli longer than propodi. Keywords: Arabian Gulf. Crabs. Crustacea. Hiplyra. Leucosiidae.
