Abstract:

Infantile nystagmus is an involuntary, bilateral, conjugate, and rhythmic oscillation of the eyes which is present at birth or develops within the first 6 months of life. It may be pendular or jerk-like and, its intensity usually increases in lateral gaze, decreasing with convergence. Up to 64% of all patients with nystagmus also present strabismus, and even more patients have an abnormal head position. The abnormal head positions are more often horizontal, but they may also be vertical or take the form of a tilt, even though the nystagmus itself is horizontal. The aim of this article is to review available information about the origin and treatment of the abnormal head position associated to nystagmus, and to describe our treatment strategies.

Abstract:

The cracking state and abnormal positions are recognized during T beam model tests using the BP neural network based novelty detection technology. Neural network training sample data is generated by analyzing the static load test data, the neural network model based on novelty detection technology is established, the state of the T beam anomaly recognition and crack position recognition is accomplished. Stepwise partition method is used in crack position recognition, which includes narrowing the crack position as the first step, specifically analyzing the sensor data, and determination of the crack position. T beam neural network model is verified by the measured data. The results show that, the method can accurately identify state and effectively identify the location of the crack.

Abstract:

Canines play an important role in the act of chewing and especially in the aesthetics of the face when you smile. They also serve as a guide to the movements of the mandible “canine management” and they are more resistant to carious lesions. Germination of the canine embryos, unlike other teeth, occurs closer to the base of the jaw, so they erupt later than all front teeth, encountering a number of barriers and, above all, lack of space in the dental arch or its absence in case of early loss of temporary teeth. Given that the canines erupt after the incisors and the first premolars, it is possible to prevent their retention and abnormal eruption in the dental arch. This can be done by timely detection of changes in their main inclination, both to the base of the jaw and relative to the inclination of the erupted teeth, especially lateral incisors, the roots of which serve as a guide axis for canine eruption. The aim of the research was to increase the effectiveness of treatment of retention and abnormal eruption of canines by developing a method for their prediction and timely detection. During the research, 52 patients aged from 7 to 25 years, were divided into four age groups, and they were examined and admitted for orthodontic treatment: I group – 12 patients (23,1%) aged from 7 to 9 years, - with early variable occlusion; II group – 16 patients (30,7%) aged from 10 to 12 years, - at the final stage of variable occlusion; III group – 12 patients (23,1%) aged from 13 to 15 years, - with early permanent occlusion; IV group – 12 patients (23,1%) aged from 16 to 25 years, - with a permanent bite. All patients did not have acute occlusal abnormalities. The following research methods were used during the examination: clinical (presence of abnormal position of the canines in parents and close relatives); anthropometric (measurements on diagnostic models); radiological, mainly orthopantomography (measurement of the axial inclination of the canines relative to the base of the jaw and adjacent teeth) and static research methods. Research in all four groups determined that the inclining of the upper canines to the base of the jaw, averaged on the Maxilla – 86,4° (right side – 86,7°, left side – 86,2° with a difference – 0,5°), and on Mandible – 100,75° (right side – 100,7°, left side – 100,8° with the difference – 0.1°). Axial inclinations of the upper lateral incisors averaged 99,1° (right side – 95,8°, left side – 102,5° with the difference – 6,7°), and lower lateral incisors – 100,65° (right side – 100,7°, left side – 100,8° with the difference – 0,1°). The difference in the inclinations of the canines and lateral incisors on the Maxilla averaged 11,6° (right side – 9,5°, left side – 13,7° with the difference 4,2°) and on the Mandible – 8,9° (right side – 8,6°, left side – 9,3° with the difference – 0.7°). As for these indicators in patients of each of the four age groups, they varied significantly. Conducted research has detected that the most objective indicator in the eruption of abnormal eruption of canines is the significant difference in their inclinations with lateral incisors, which serve as the guiding axis of eruption. In patients from the I group, the difference in inclinations and lateral incisors was on the Maxilla on the right – 9,3°, on the left – 16,0°; and on the Mandible – right side 11,8°, left side 12,2°. In patients from the II group the difference in inclinations and lateral incisors was on the Maxilla on the right side – 13,8°, on the left side – 18,1°; and on the Mandible – right side 7,1°, left side 10,5°, in accordance. In the III group on the Maxilla from the left side – 10,6° and right side – 8,6°; and on the Mandible – 9,6° and 11,1°, in accordance. The difference in inclinations of these teeth was on the Maxilla – right side 4,3°, left side 12,3°; and on the Mandible – 6,0° and 3,3°, in accordance. On this basis, we proposed a method for predicting abnormal eruption of the canines using the constructed “canine triangle” on the orthopantomogram formed by the intersection of the axial inclinations of the canines and lateral incisors (ւВ) with the plane of the base of the jaw, on which the segment (a) is the base of the triangle. The more difference between the inclinations of the canines and lateral incisors ( > 10°), that is the larger the value (ւВ), the longer the size of the base (a) of the triangle, which indicates the difficulty of eruption of the canines in the future (outside the dentition or retention). Timely detection of a significant difference in the inclinations of canines and lateral incisors can prevent abnormal eruption and retention of canines by adjusting their inclinations with lateral incisors and eliminating the lack of space in the early stages of formation of the dental apparatus.

Abstract:

AbstractSeven specimens of Xiphinema dentatum with abnormal genital organs were found in the same population. Normal females are amphidelphic with the vulva located slightly anterior to the mid-body. Of some 24 000 females examined, six were found to be abnormal. One has a normally developed genital tract, but located in an abnormally posterior position. Two females have two complete systems each, one system in the normal position, and the other well posterior. Another female has a normal posterior branch, while the anterior one is abnormally branched at the pars dilatata uteri into two oviducts and ovaries, one ovary being degenerate. Another two females lack central parts of the system, the remaining distal parts being fused proximally. Males are rare in this species, sometimes having a fully developed diorchic genital tract, but usually with only the copulatory apparatus developed. Of the 137 males examined, one has a normal copulatory apparatus, lacks the seminal duct and has two abnormal masses of tissue corresponding to the position where the testes would normally be located.

Abstract:

SummaryA heterozygous GT transversion at position 1388 of the protein C (PC) gene which predicted the substitution of Arg-1 to a Leu (PCR-1L) was identified in a thrombophilic patient. The PCR-1L was purified from the patient’s plasma by immunoaffinity chromatography using Ca++-independent and Ca++-dependent monoclonal antibodies. NH2-terminal sequencing of the light chain of PCR-1L revealed two amino acid sequences: one was identical to the complete propeptide sequence of PC, while the other matched the normal PC light chain sequence elongated by one amino acid (Leucine at position 1). Activated PCR-1L/propeptide exhibited normal amidolytic and impaired anticoagulant activity. Thus, the substitution of a Leu for an Arg at position -1 of PC shifts the propeptidase cleavage site by one amino acid. In addition, in PCR-1L/propeptide the propeptide cleavage at Lys-2 is less efficient since approximately 60% of PC variant molecules present in patient’s plasma retained the entire propeptide. Our findings suggest that depending on the specific amino acid substitution at position-1, PC can be secreted in plasma containing the entire propeptide attached to the light chain. Impaired interaction of elongated APC molecules with a membrane-surface and/or factor Va which is the physiological substrate for APC, is manifested in vivo by thrombophilia.

Abstract:

The objective of this study was to determine whether a correlation exists between abnormal pronation and functional leg-length discrepancies. Visual assessment and a pelvic thrust maneuver were used to identify the functionally short leg in 56 indigenous Mexicans (20 males and 36 females; mean age, 33 years; mean weight, 59 kg; and mean height, 1.60 m). The Foot Posture Index was used with a modified stance position to identify the more pronated foot. The posterosuperior iliac spines were used to identify the “relative” position of the innominate bones. The raw data obtained from this study were evaluated using the McNemar test for paired proportions. A significant positive correlation was found between abnormal pronation and hip position and between hip position and functional leg-length discrepancy. These results are consistent with a theoretical ascending dysfunctional pelvic model: Abnormal pronation pulls the innominate bones anteriorly (forward); anterior rotation of the innominate bones shifts the acetabula posteriorly and cephalad (backward and upward); and this shift in the acetabula hyperextends the knees and shortens the legs, with the shortest leg corresponding to the most pronated foot.

Abstract:

Purpose. Randomized controlled trial aimed at comparing surgical outcomes in a group of patients suffering from hyperfunction of the inferior oblique (IO) muscle with abnormal head position (AHP). The surgical techniques being compared are Recession and (thread) Controlled Myotomy.Materials and Methods. The group of 20 patients suffering from medium-high hyperfunction of the IO was assessed through an ophthalmological and orthoptic examination. 10 patients underwent traditional Recession (Group A) and 10 were treated with Controlled Myotomy (Group B).Results. The average age was 19 years ± 10.7 SD. After 1 year, 20% of Group A showed a small Vertical Deviation associated with a small AHP, while 80% had orthophoria and 40% of them had a small AHP. 80% of Group B showed a small Vertical Deviation associated with an equally small AHP, while 20% had orthophoria with a full resolution of AHP.Conclusion. Based on the results obtained and the fewer intrasurgical risks involved, thread Controlled Myotomy proved to be a valid alternative to Recession. Furthermore, in case of Recession, over the long period a small residual AHP remained in the patients who had orthophoria, unlike Myotomy which led to a total resolution.

Abstract:

Objective: To observe the effect of abnormal Cardiotocography to delivery interval on perinatal outcome in terms of Apgar score. Study design: Descriptive case series study. Place and duration of study: Baqai Medical University department of obstetrics and gynecology Fatima Hospital Karachi from Jan 2011 to July 2011. Material and method: One hundred patients were registered who had pathological Cardiotocography. Bishop’s score was noted and decision to deliver the patient was made according to the abnormality, and bishop’s score. If bishop’s score was good and vaginal delivery was imminent, then her second stage was shortened by operative vaginal delivery. Fetal distress was managed by left lateral position, O2 inhalation and hydration. If delivery was not imminent then decision of urgent LSCS was made, meanwhile fetal distress was managed. Decision – delivery interval was recorded, and fetal outcome was noted in terms of Apgar score and resuscitation needed. Results: During this period one hundred pregnant women at term had pathological CTG for which they were delivered urgently. Among them 12% of parturients were delivered within 30 min ,68% delivered within 30-60 min , 12% delivered in 60-90 min and only 8% were delivered in 90-120 min. Seventy four (74%) of parturients were delivered by emergency lower segment caesarean section and 26% of parturients were delivered by instrumental vaginal delivery. Fetal outcome in terms of 1 min Apgar score ,38% of neonates had Apgar score of <7 ,46% had >7 and 16% had Apgar score of <5. This group of neonates required resuscitation and 5 min Apgar was good. No neonate was admitted in Neonatal unit. Conclusions: In this study it is concluded that with fetal heart rate abnormality, if fetus is delivered within 60 min, it is not associated with poor fetal and neonatal outcome, provided fetal distress is managed while preparing for emergency lower segment caesarean section.

In the process of Original Position Statistic Distribution Analysis, many abnormal higher spark signals exist. They are believed as inclusion signals. Analyzing the time sequence and position of the abnormal spark, It is found that the higher spark signals for S and Mn will appear simultaneously . The reason is that MnS inclusion caused the element concentration enrichment at these zone. Mixing some pure MnS crystal in pure iron powder and pressed by Heat Isostatic Pressing technology, reference samples of MnS inclusion were made . Criteria of abnormal higher spark signals for Mn and S is the measured value from the “blank sample ”.After analyzing the spark behavior of these reference samples using OPA instrument, we can calculate the MnS inclusion concentration through such method. steel samples were analyzed and results is satisfactory.

Abstract:

Introduction: Resting tongue position is of crucial importance in the stability and retention of complete denture, particularly of the mandible. The retracted position of the tongue has been found to be higher in edentulous subjects when compared to dentate subjects and highest in completely edentulous individuals. Objectives: To evaluate the resting tongue position in completely edentulous as well as partially edentulous patients. Methods: 50 edentulous and 50 partially edentulous (mandible) subjects were taken. The edentulous group was divided into two groups according to the duration of edentulousness. Group A: Recently extracted edentulous subjects (< 1 year), Group B: Long term edentulous subjects (> 1 years). The partially edentulous group was divided into 4 groups according to Kennedy classification. The resting tongue positions of all the individuals were determined. The data was analyzed using SPSS statistical tests like mean, standard deviation, proportion, Chi-square test and Independent T-test. Results: In complete edentulous group, the abnormal upper was the most frequent (38%). In partial edentulous group, the normal lower was the most frequently observed tongue position with 34%. The abnormal tongue position was found in 68% and 40% in completely edentulous and partially edentulous subjects respectively. Conclusion: Retracted resting tongue position is found to be higher in completely edentulous subjects than partially edentulous ones.

Full text

Abstract:

Background: Twenty-two children from Jiutepec, Mexico, were studied to determine whether a correlation exists among foot motion, the position of the innominates, and vertical facial dimensions (ie, the distances between the outer corners of the eyes [the exocanthions] and the ipsilateral outer margins of the lips). Methods: Three null hypotheses were constructed and tested using the one-sample t test. Hypothesis A: there is no relationship between abnormal foot pronation and hip position; Hypothesis B: there is no relationship between hip position and vertical facial dimensions; and Hypothesis C: there is no relationship between abnormal foot pronation and vertical facial dimensions. Results: The three null hypotheses were rejected. Conclusions: An ascending foot cranial model was theorized to explain the findings generated from this study: 1) due to the action of gravity on the body, abnormal foot pronation (inward, forward, and downward rotation) displaces the innominates anteriorly (forward) and downward, with the more anteriorly rotated innominate corresponding to the more pronated foot; 2) anterior rotation of the innominates draws the temporal bones into anterior (internal) rotation, with the more anteriorly rotated temporal bone being ipsilateral to the more anteriorly rotated innominate bone; 3) the more anteriorly rotated temporal bone is linked to an ipsilateral inferior cant of the sphenoid and superior cant of the maxilla, resulting in a relative loss of vertical facial dimensions; and 4) the relative loss of vertical facial dimensions is on the same side as the more pronated foot.

Abstract:

IntroductionFixational saccades are miniature eye movements that constantly change the gaze during attempted visual fixation. Visually guided saccades and fixational saccades represent an oculomotor continuum and are produced by common neural machinery. Patients with strabismus have disconjugate binocular horizontal saccades. We examined the stability and variability of eye position during fixation in patients with strabismus and correlated the severity of fixational instability with strabismus angle and binocular vision.MethodsEye movements were measured in 13 patients with strabismus and 16 controls during fixation and visually guided saccades under monocular viewing conditions. Fixational saccades and intersaccadic drifts were analysed in the viewing and non-viewing eye of patients with strabismus and controls.ResultsWe found an increase in fixational instability in patients with strabismus compared with controls. We also found an increase in the disconjugacy of fixational saccades and intrasaccadic ocular drift in patients with strabismus compared with controls. The disconjugacy was worse in patients with large-angle strabismus and absent stereopsis. There was an increase in eye position variance during drifts in patients with strabismus. Our findings suggest that both fixational saccades and intersaccadic drifts are abnormal and likely contribute to the fixational instability in patients with strabismus.DiscussionFixational instability could be a useful tool for mass screenings of children to diagnose strabismus in the absence of amblyopia and latent nystagmus. The increased disconjugacy of fixational eye movements and visually guided saccades in patients with strabismus reflects the disruption of the fine-tuning of the motor and visual systems responsible for achieving binocular fusion in these patients.

Abstract:

Sigmoid colon is one of the most variable parts of the large intestine. Here we report a very rare type of variation of the sigmoid colon. This variation was observed during the routine dissections for undergraduate medical students at Melaka Manipal Medical College (Manipal Campus) India in September 2012. In the current case, the sigmoid colon was about 60cms long and made an inverted U shaped loop in front of the descending colon and the left kidney. It had a sigmoid mesocolon which covered the left kidney. The sigmoid colon had an ascending and a descending limb. This position of sigmoid colon and its mesocolon is dangerous as it can get twisted to form a volvulus. It also might cause confusions in radiologic and sigmoidoscopy techniques.

Abstract:

Venous air embolism occurs when air is entrained into the venous system and travels to the right heart and pulmonary circulation, and commonly occurs as a complication in laparoscopic, neurosurgical and cardiac surgeries. We present a case of abnormal end-tidal carbon dioxide capnography tracing in the lateral position in a laparoscopic major liver procedure and discuss the potential novel use of this as a red flag in aiding the medical practitioner to diagnose air embolism.

Abstract:

SummaryWe have identified a γ-Arg–275 to His substitution in an abnormal fibrinogen designated as “fibrinogen Saga” characterized by impaired fibrin monomer polymerization. By chromatofocusing chromatography, we isolated normal and abnormal fragment Dl populations separately from the plasmic-calcium digests of fibrinogen derived from the propositus, a heterozygote for the abnormality. We found that both normal and abnormal fragment D1’s were similarly protected from digestion by plasmin in the presence of calcium ions and further degraded to fragments D2 and D3 due to cleavage of the γ-chain remnant when calcium ions were replaced by chelating agents. Abnormal fragment D1 failed to inhibit both thrombin-clotting of normal fibrinogen and polymerization of normal fibrin monomer, while normal D1 exhibited marked inhibitory activities. In an aberrant peptide comprising residues γ–274–302 isolated by HPLC from the lysyl endopeptidase-digests of abnormal fragment D1, we identified a His substituting for an Arg at position 2, which corresponds to position 275 of the mutant γ-chain

Abstract:

Twenty runners displaying abnormal subtalar joint pronation were selected for this study, the purpose of which was to investigate the effects of extrinsic rearfoot posted orthoses on frontal plane rearfoot and tibial position. Numerous temporal events were measured and compared for three different conditions: acrylic post, Birko post, and no post. The results suggested that rearfoot posts have a somewhat limited function in foot orthotic therapy and that the choice of posting material is of limited functional value.

Abstract:

People often say that humans are omnivores in order to justify eating meat as normal and veganism as abnormal. The ‘Omnivore's Argument’ is one of the arguments that vegetarians and vegans encounter when meat-eaters try to defend the moral acceptability of body parts on their plate. When responding to this argument, the position of the vegan is similar to the atheist who time and again is confronted with the same fallacious arguments in support of the existence of god(s). Veganism and atheism are both ethical default positions. Similarly, not killing other people is also a default position.

Abstract:

ObjectiveTo determine whether different phenotypes of cervical dystonia (CD) express different types and levels of somatosensory impairment.MethodsWe assessed somatosensory function in patients with CD with and without tremor (n = 12 each) and in healthy age-matched controls (n = 22) by measuring tactile temporal discrimination thresholds of the nondystonic forearm and proprioceptive acuity in both the dystonic (head/neck) and nondystonic body segments (forearm/hand) using a joint position‐matching task. The head or the wrist was passively displaced along different axes to distinct joint positions by the experimenter or through a robotic exoskeleton. Participants actively reproduced the experienced joint position, and the absolute joint position‐matching error between the target and the reproduced positions served as a marker of proprioceptive acuity.ResultsTactile temporal discrimination thresholds were significantly elevated in both CD subgroups compared to controls. Proprioceptive acuity of both the dystonic and nondystonic body segments was elevated in patients with CD and tremor with respect to both healthy controls and patients with CD without tremor. That is, tactile abnormalities were a shared dysfunction of both CD phenotypes, while proprioceptive dysfunction was observed in patients with CD with tremor.ConclusionsOur findings suggest that the pathophysiology in CD can be characterized by 2 abnormal neural processes: a dysfunctional somatosensory gating mechanism involving the basal ganglia that triggers involuntary muscle spasms and abnormal processing of proprioceptive information within a defective corticocerebellar loop, likely affecting the feedback and feedforward control of head positioning. This dysfunction is expressed mainly in CD with tremor.

Abstract:

Here, we report a patient with persistent positional upbeat nystagmus in a straight supine position with no evident abnormal central nervous system findings. A 43-year-old woman with rotatory positional vertigo and nausea visited our clinic 7 days after the onset. Initially, we observed persistent upbeat nystagmus in straight supine position with a latency of 2 s during the supine head roll test. However, an upbeat nystagmus disappeared on turning from straight to the left ear-down supine position, and while turning from the left to right ear-down position, an induced slight torsional nystagmus towards the right for >22 s was observed. In the Dix–Hallpike test, the left head-hanging position provoked torsional nystagmus towards the right for 50 s. In prone seated position, downbeat nystagmus with torsional component towards the left was observed for 45 s. Neurological examination and brain computed tomography revealed no abnormal findings. We speculated that persistent positional upbeat nystagmus in this patient was the result of canalolithiasis of benign paroxysmal positional vertigo of bilateral posterior semicircular canals.

Abstract:

Objective: despite the technologic advances in myocardial perfusion imaging, we keep using an uncomfortable and sometimes impracticable patient position - supine with arms raised above the head (U). The purpose of this study was to investigate whether perfusion and functional cardiac gated SPECT scan results of acquisition U are equivalent to another position modality: supine with arms down at the sides of the trunk (D). Methods and Results: we performed U acquisition and in sequence D acquisition in 120 patients (pts) using a one-day MPI (rest-gated/stress), with 99mTc-sestamibi (370 MBq and 1110 MBq). Images were processed by the iterative reconstruction method (OSEM). Rest (R) and stress (S) studies were scored using 17-segments model. Functional parameters (left ventricular ejection fraction, and volumes) were automatically obtained by the quantitative gated SPECT (QGS) program. According to the degree of stress defects observed in U study, the patients were categorized in two subgroups: normal (SSS ≤ 3 or < 5%) and abnormal (SSS>3 or ≥ 5%). Shoulder/back pain occurred in 23.3% of U patients and in 5% of D. No significant differences between U and D were found for SSS (p = 0.82) and SRS (p = 0.74) in normal group. In abnormal group, good correlation was found between U and D modes for SSS (Rho = 0.95, p = 0.0001) and SRS (Rho = 0.96 p = 0.0001), but the mean SSS (12.53 ± 7.54) and SRS (10.60 ± 7.08) values of D were significantly lower (p < 0.05) than SSS (13.43 ± 6.81) and SRS (11.33 ± 6.97) of U mode. Function measurements presented good correlations, except for end-diastolic volume (p = 0.0001). Conclusion: although D mode appears to be more comfortable and presented a good correlation with U values of SSS and SRS, in abnormal pts, the extent and severity of defects can be underestimated. Considering clinical implications of an accurate perfusion measurement, the acquisition with the arms down should be avoided.

Aim. To diagnose pathological teeth location suggested many methods of research. However, the available literature there is no information concerning the characteristics of the abnormal protrusion or retrusion, not showing the diagnostic criteria determine the position of the cutters for their planned positions in constructive is incorrect. Materials and methods. Survey of 62 people coming of age in the first period, two clinical groups. In 1st group included 24 patients with physiological occlusion, and the 2nd (38 persons) with abnormal occlusion. In each group were identified in patients with protrusion or retrusion incisors. Evaluation of vertical overlap conducted on MRI and plaster models of the jaws between horizontal lines passing through the cutting edge of the incisors of the upper and lower jaws parallel to the occlusal plane. Results. People with Group 1 protrusion incisors angle was 149.55 3.92. Tork upper incisors were 24.36 2.39 degrees. When retrusion incisors angle was 151.47 2.94, tork upper incisors was 5.85 1.42. In this case, the vertical overlap is in the sagittal and 2-3 mm is not exceeded. Group 2 patients, as a rule, noted the violation of form dental arches in the anterior segment. Conclusion. To diagnose physiological protrusion or retrusion incisors used values overlap in the sagittal and vertical direction, consistent with each other and do not exceed 3 mm.
