Published: April 2021

В современной литературе широко обсуждается проблема коморбидности тревожных расстройств и расстройств пищевого поведения. Однако, на сегодняшний день тематика коморбидности социальной тревоги и расстройств пищевого поведения среди студентов, в частности, студентов медицинских ВУЗов, остается малоосвещенной. Целью данного исследования послужил анализ данных литературы последних лет (2011 год и позднее), посвященных проблематике коморбидности пищевых расстройств и социальной тревоги среди обучающихся высшей медицинской школы. Особую значимость представляют работы по выявления предикторов развития и персистирования социальной фобии и пищевых нарушений среди студентов медицинских ВУЗов, поскольку специфика и сложность образовательной программы способствует формированию тревожных расстройств и пищевых нарушений, более того, социальные страхи и фобии приводят к ухудшению академической успеваемости обучающиеся. Помимо этого, студенты медицинского направления сами в будущем должны будут оказывать помощь пациентам, обеспечивая здоровье нации, следовательно, студентам высшей медицинской школы важно иметь как соматическое, так и психическое здоровье
The problem of comorbidity of anxiety disorders and eating disorders is widely discussed in the modern literature. However, to date, the topic of comorbidity of social anxiety and eating disorders among medical students remains poorly uncovered. The purpose of this study is to analyze the literature data of recent years (2011 and later) on the problems of comorbidity of eating disorders and social anxiety among students of higher medical school. Of particular importance is the work on identifying predictors of the development and persistence of social phobia and eating disorders among medical students, since the specificity and complexity of the educational program contributes to the formation of anxiety disorders and eating disorders. Moreover, social fears and phobias lead to a deterioration in academic performance of students. In addition, medical students themselves in the future will have to provide assistance to patients, ensuring the health of the nation, therefore, it is important for students of higher medical school to have both somatic and mental health

Surgery is a form of therapy that can threaten the integrity of a person's body and soul. The psychological response that usually occurs in preoperative patients is anxiety. Anxiety is an emotional reaction to subjective individual judgment, which is influenced by the subconscious and the cause is not specifically known. Type of research is quantitative and qualitative research (method mixed). This research was conducted at DR. R.M Djoelham general hospital Binjai. Qualitative population of surgeons, anesthetists and nurses at RSUD DR. RM Djoelham Binjai, samples obtained by Purposive Sampling as many as 33 people. Data were analyzed by univariate, bivariate (Chi Square), Multivariate (logistic regression). Based on these results it is concluded that there is a relationship between providing information, consultation and education on patient anxiety. Based on the results of the bivariate analysis, it is found that there is a relationship in the dimension of Information Giver has a value of p (sig) 0.037, consultation (sig) 0.005, education p (sig) 0,002. The concluded that there is a relationship between providing information, consultation and education on patient anxiety. Based on the results of interviews from informants, it was found that the provision of information, consultation and education before or after the operation had been implemented, both DPJP doctors, anesthetists and nursing staff.
On the Detection of Habitable Trojan Planets in the Kepler Circumbinary Systems
Authors: Sudol Jeffrey J. , Haghighipour Nader 
Published: April 2021

Abstract
We present the results of a study of the prospect of detecting habitable Trojan planets in the Kepler Habitable Zone circumbinary planetary systems (Kepler-16, -47, -453, -1647, and -1661). We integrated the orbits of 10,000 separate N-body systems (N = 4, 6), each with a one Earth-mass body in a randomly selected orbit near the L
4 and L
5 Lagrangian points of the host HZ circumbinary planet. We find that stable Trojan planets are restricted to a narrow range of semimajor axes in all five systems and limited to small eccentricities in Kepler-16, -47, and -1661. To assess the prospect of the detection of these habitable Trojan planets, we calculated the amplitudes of the variations they cause in the transit timing of their host bodies. Results show that the mean amplitudes of the transit timing variations (TTVs) correlate with the mass of the transiting planet and range from 70 minutes for Kepler-16b to 390 minutes for Kepler-47c. Our analysis indicates that the TTVs of the circumbinary planets caused by these Trojan bodies fall within the detectable range of timing precision obtained from the Kepler telescope’s long-cadence data. The latter points to Kepler data as a viable source to search for habitable Trojan planets.
SALMONELLA VERTEBRAL OSTEOMYELITIS: A COMPLICATION OF SALMONELLA AORTITIS
Authors: Baird Robert A , Anderson Nolan J , Bloch Jack H 
Published: April 2021

ABSTRACT: Salmonella vertebral osteomyelitis of the lumbar spine is encountered as a complication of Salmonella arteritis. Salmonella organisms, especially those of the choleraesuis and typhimurium species, invade the lamina intima of a diseased or atherosclerotic abdominal aorta, penetrate its wall, and cause the formation of a mycotic aneurysm. Further spread of thé infectious process through the aneurysmal aortic wall leads to infection of the retroperitoneum, psoas abscess formation, and osteomyelitis of the adjacent lumbar vertebrae. A review of the literature reveals a 77% mortality rate. Successful treatment of this association requires resection of the abdominal aneurysm and debridement of the retroperitoneum, extra-anatomic bypass grafting, and appropriate antimicrobial therapy.

RESULTS OF SURGICAL TREATMENT OF KNEE INSTABILITIES
Authors: Kiss Imre , Gáspár Levente , Szepesi Kálmán 
Published: April 2021

ABSTRACT
Between January 1, 1981 and January 5, 1987, 146 reconstructive operations for acute (39) and chronic (107) knee instabilities were performed. The majority of the acute cases were anteromedial (24), and of tbe chronic instabilities, 33 were anteromedial, 14 anterolateral, and 53 combined anteromedialanterolateral. In terms of suture, replacement, and reinforcement of the damaged structures of the acute cases, 32 were good, 6 fair, and 1 poor, while the reconstruction, according to Müller, for chronic instabilities produced good results in 34, fair in 59, and poor in 14. It is essential that such operations be performed by a trained surgical team. For success, precise knowledge of anatomy, exact examination, accurate diagnosis, adequate surgical techniques, and careful postoperative treatment are essential.

Published: April 2021

ABSTRACT
Surgical treatment of 74 cases of impending and established metastatic pathologic fractures were analyzed. On the basis of various reports, the incidence of bone lesions, boneseeking primary tumors, lesion sites, diagnostic techniques and possibilities, as well as indications for and methods of surgical treatment, are surveyed. Surgical intervention is only one aspect of the different components of general treatment in bone metastases. An aggressive surgical procedure yields very satisfactory results in most cases, compared with those of conservative treatment.
THE EFFECT OF EARLY ANTERIOR APPROACH OPEN REDUCTION WITH FUNCTIONAL POSTOPERATIVE TREATMENT ON THE EARLY DEVELOPMENT OF THE ACETABULUM IN CDH
Authors: Szepesi Kálmán , Biró Béla , Fazekas Katalin , Szüc Gabriella 
Published: April 2021

ABSTRACT
Between 1980 and 1983, 30 anterior approach open reductions were performed on congenitally dislocated hips of 29 patients after unsuccessful conservative treatment; patients were between 6 and 18 months old. After the removal of the obstruction from the acetabulum, the reduction was performed with preservation of the limbus. Some part of the capsule was removed to constrict and tighten it and to prevent redislocation. This capsuloplasty demonstrates the success of a Pavlik harness and abduction splint postoperatively, without plaster fixation. The accelerated development of the acetabulum could be observed on radiograph by this functional treatment, compared to the control group treated with the usual hip spica postoperatively. The development of the acetabulum on the operated side almost equals the sound side within a year. If the operation was performed earlier, joint development would be quicker.
PERCUTANEOUS NUCLEOTOMY: TECHNIQUE WITH DISCOSCOPY
Authors: Schreiber A , Leu Hj 
Published: April 2021

ABSTRACT
In its first decade of use, percutaneous nucleotomy has proven its value in decompressive indications for lumbar disc disease. Indications include contained disc herniations as isolated pathology, or in combination with other lumbar pathology at risk for decompensation after open hemüaininotomy, eg, spondylolysis/olisthesis or former open operative procedures. The precise indications underline the need for conclusive preoperative screening, such as disco-scan and contrastdiscomanometry. Overall results are 85% favorable. Percutaneous intervertebral fusion is also presented.
GIRDLESTONE'S MODIFIED RESECTION ARTHROPLASTY
Authors: Böhler M , Salzer M 
Published: April 2021

ABSTRACT
Thirty-three patients were operated for septic (n=20) and aseptic (n = 13) loosening of their hip prostheses using Girdlestone's operation over 10 years. An average of 46.6 months later, 22 of these patients were given a follow-up examination. Clinical evaluation according to Harris showed an improvement in mean values from 25 to 53 points, which can be attributed mainly to a marked reduction in pain, as function remained poor and the patients still depended on walking aids. The infection ceased in 92% of the patients with septic prosthesis loosening.
ANATOMIC VARIATIONS OF THE BLOOD SUPPLY OF THE SOLEUS MUSCLE
Authors: Sadasivan Kalia K , Ogden John T , Albright James A 
Published: April 2021

ABSTRACT
A total of 36 cadaver and fresh amputation specimens were studied by dissection. Two vascular patterns were identified - a segmental posterior tibial artery (Type 1) and a proximally dominant posterior tibial artery (Type 2). Type 1 was seen in 77.8% of cases, and Type 2 in 22.2%. Injection studies in five fresh specimens demonstrated numerous crossconnections between the two halves of the muscle. A distally based hemisoleus flap should not be performed when a Type 2 vascular pattern is encountered. Also, vascular cross-connections between the two halves of the soleus muscle should be preserved, when possible.
DISPLACED FRACTURES OF THE HEAD AND NECK OF THE RADIUS IN CHILDREN: OPEN REDUCTION AND TEMPORARY TRANSARTICULAR INTERNAL FIXATION
Authors: Merchan E Carlos Rodriguez 
Published: April 2021

ABSTRACT
This report reviews the results of 36 children surgically treated for fractures of the head and neck of the radius. Indications for operation were: displacement over 2 mm and/or angulation over 45e. Treatment included open reduction and temporary internal fixation with a K-wire transfixing the joint. Eighteen children had a good result, 8 had a fair result, and 10 had a poor result. It appears that when radial head fractures are associated with severe displacement, a high rate of fair and poor results can be expected, despite treatment by open reduction and temporary internal fixation.
L PLATE FIXATION FOR OSTEOTOMIES
Authors: Stevens Peter M 
Published: April 2021

ABSTRACT
It is generally acknowledged that stable fixation of osteotomies offers certain benefits, including maintenance of predictable alignment, while permitting rapid mobilization and rehabilitation. A variety of implants are available which require technical proficiency and familiarity by the surgeon for successful implantation. The ability to customize implants before or during surgery allows the surgeon critical control in a variety of situations. An L plate, which is a pre-bent dynamic compression plate (DCP), applied as a tension band with interfragmentary screws serves this purpose well.
PROXIMAL FEMORAL FOCAL DEFICIENCY: EVALUATION AND MANAGEMENT
Authors: Bryant D'Orsay D , Epps Charles H 
Published: April 2021

ABSTRACT
Proximal femoral focal deficiency is a rare congenital anomaly characterized by limb malrotation, deficiency of the iliofemoral articulation, and limb length discrepancy. Advances in radiology, such as computed tomography and magnetic resonance imaging, have enhanced the assessment of pelvicfemoral instability prior to ossification of the femoral capital epiphysis. The histopathology of the fetal proximal femoral growth plate has been described, which has increased our knowledge about the etiology of the proximal femoral malformation. Data are now available regarding the long-term functional status of patients with severe acetabular dysplasia (Aitken Class C or Class D deformity) following nonoperative management of the hip. A review of the current knowledge regarding proximal femoral focal deficiency is presented to assist the orthopedic surgeon in evaluation and management.
PREVENTING DVT FOLLOWING TOTAL KNEE REPLACEMENT: A REVIEW OF RECENT CLINICAL TRIALS
Authors: Fitzgerald Robert H 
Published: April 2021

ABSTRACT
Deep vein thrombosis (DVT) following total hip or knee arthroplasty is a frequent complication which can cause fatal pulmonary embolism (PE). Although many different approaches to its prevention have been attempted, low-dose warfarin has become the standard treatment for the prevention of thromboembolic disease following total hip and knee arthroplasty. Although subcutaneous heparin can reduce the incidence of thromboembolic disease, it has been associated with excessive bleeding complications. The introduction of low molecular weight heparins promises fewer bleeding complications with efficacy equal to that of warfarin. We wish to report the results of a randomized, prospective study comparing a low molecular weight heparin with low dose warfarin in the prevention of thromboembolic disease following total knee arthroplasty (TKA).
A Modular Endoprosthetic System for Tumor and Non-Tumor Reconstruction: Preliminary Experience
Authors: Freedman Eric L , Eckardt Jeffrey J 
Published: April 2021

ABSTRACT
Though originally designed to facilitate the management of primary malignant bone tumors, the indications for the Howmedica Oncology modular endoprostheses have expanded to include the reconstruction of metastatic lesions, failed internal fixation of difficult trauma problems, and failed conventional and custom tumor endoprostheses. Between July 1989 and August 1992, 24 patients underwent 25 procedures, either proximal humeral replacement (7), proximal femoral replacement (5), distal femoral replacement (9), or total femoral replacement (4). Diagnoses included primary bone tumor (6), metastases (5), and failed previous orthopedic intervention (14). Two early and four late complications in five patients were all treated successfully with surgical or nonoperative treatment. Preliminary functional results indicate very satisfactory results. Modular endoprostheses appear to be effective in the treatment of a wide range of diagnoses, not limited to the reconstruction following primary malignant bone tumor resections.
Radiation-Induced Physical Changes in UHMWPE Implant Components
Authors: Naidu Sanjiv H , Bixler Brian L , Moulton Mark J R 
Published: April 2021

ABSTRACT
Post-irradiation aging of ultra-high molecular weight polyethylene (UHMWPE) is not well understood. Retrieval studies and in vitro aged specimens have shown oxidative changes along with increases in crystallinity. Critical analysis and review of the polymer science and polymer physics literature shows that while oxidation may be important during the first year post-irradiation, subsequent aging occurs because of initial γ radiation-induced chain scission leading to eventual isothermal crystallization of polymer chains in the amorphous regions of the UHMWPE bulk. Mechanical properties of aged UHMWPE are not as yet clear and, until such data become available, γ irradiation sterilization must be used with caution.
The Use of the Ilizarov Technique in the Correction of Lower Extremity Deformities in Children
Authors: Bassett George S , Morris John R 
Published: April 2021

ABSTRACT
The first time the Ilizarov technique was used at Children's Hospital of Los Angeles, 25 limb segments were treated in 15 patients. Thirteen segments (52%) required angular correction, 6 (24%) required lengthening, and 6 (24%) required both angular correction and lengthening. Average angular correction was 21° (8° to 41°); average length gained was 44 mm (25 to 85 mm). All patients except two achieved preoperative goals.
A total of 17 minor (.68/limb) and four major (.16/limb) complications occurred in the 25 limb segments in the study. The total complication rate was .84 complications per limb segment. The most common complication was pin tract infection (1 1 patients). This comprised 52% of complications and occurred in 44% of limb segments.

Authors: Silveri Christopher P , Simpson J Michael , Simeone Frederick A , Balderston Richard A 
Published: April 2021

ABSTRACT
Eighty-four consecutive patients with posterolateral cervical disk herniation treated by keyhole foraminotomy between 1980 and 1987 were reviewed. Radicular pain was the most common presenting complaint Weakness was present in 59 patients.
Sixty patients were available for long-term follow up, averaging 6.1 years. Fifty-six patients' results were graded as excellent. Three patients had good results and one fair result was noted. There were no poor results. Preoperative pain symptoms were relieved in all patients. There were no significant complications.
The posterolateral keyhole foraminotomy is an efficient means of decompressing lateral soft disk herniations, without the risk of an anterior approach or iliac crest bone harvest. Careful patient selection and use of an operative microscope are essential in obtaining consistent, excellent results.
Skin Impedance Comparisons of Electrodes for Electro-Oculography
Authors: Lee Jong Bok , Reinecke Robert D 
Published: April 2021

ABSTRACT
In an effort to define the most comfortable electrode needing the simplest skin preparation with low and stable skin impedance, we compared the impedance between skin electrodes and Stat-Trace Il SM 02 EKG electrodes (Niko Med USA, New Brunswick, NJ) - the latter being renamed "dry electrodes" because they are used without electrolyte paste - on 12 normal subjects with two different skin preparations, with and without alcohol. The dry electrodes were found to have lower impedance than the skin electrodes. With each skin preparation the alcohol scored better, 7.2 kOhm vs 16.5 kOhm, respectively, and "no preparation" worse, 13.8 kOhm vs 22.7 kOhm, respectively, (but still acceptable when the dry electrode was used). The dry electrode's impedance was quite stable from the moment of application while the skin electrode's impedance drifted dramatically for 30 minutes. If the dry electrode was halved in area of skin contact, as often is necessary with the nasal electrode in children, the impedance rose proportionally but remained acceptable. We conclude that the new dry electrodes give us improved electro-oculography records and suggest their use, particularly for infants and young children where ease of application and simple skin preparation are particularly important.

ABSTRACT
Extensive persistent pupillary membranes which occlude the pupil may occur in isolation or in association with other ocular anomalies. Amblyopia may result if the membranes are extensive. We favor nonsurgical intervention except if unusual circumstances are present as demonstrated in one of our two cases.
Monocular Congenital Cataracts: Psychological Effects of Treatment
Authors: Smith Kyle H , Baker David B , Keech Ronald V , Adams Louis W , Rosa Robert H , Austin Christopher J , Austin Karla M 
Published: April 2021

ABSTRACT
Visual success in the treatment of monocular congenital cataracts requires early surgery, and aggressive, long-term amblyopia management and optical correction. These children will have their only normally seeing eye patched for a significant percentage of their early childhood years. We have been concerned about the possibility of an adverse psychological impact of this form of treatment. This study utilized two standardized testing instruments to evaluate the incidence of developmental delay and behavioral problems in children treated for monocular congenital cataracts. A total of 22 children were evaluated with one or both of these instruments and compared to a control group of 18 normal siblings. There was no statistically significant evidence of developmental delay or increased behavioral problems in the treatment group.
Cosmetic Surgery for a Fatally Ill Infant
Authors: Frankel Carl A , Juengst Eric T 
Published: April 2021

ABSTRACT
The ethical and clinical dimensions of strabismus surgery in a case of an infant with mucolipidosis type Il are discussed. Three sets of considerations are relevant to the decision of performing such surgery: professional obligations to protect patients from futile or contraindicated treatment; parental authority to assess the risks and benefits for elective pediatric care; and the role of the family as patient. We argue that, when weighed together in the context of this case, these considerations can support a decision to perform the surgery upon parental request, despite the patient's poor prognosis.
Borderline Melanocytic Tumor of the Conjunctiva: Diagnostic and Therapeutic Considerations
Authors: Margo Curtis E , Roper Daniel L , Hidayat Ahmed A 
Published: April 2021

ABSTRACT
A clinically benign appearing nevus was surgically excised from the conjunctiva of a 13-year-old girl because of complaints that it had recently enlarged. Histologically, the melanocytic lesion displayed considerable cytologic atypia and showed signs that were consistent with malignant transformation. Because of the rarity of conjunctival melanomas in children, the case was reviewed by several experienced pathologists and dermatopathologists whose diagnoses ranged from benign nevus with atypia to malignant melanoma. When the biologic potential of certain melanocytic lesions cannot be accurately predicted histologically, treatment and follow up must be individualized. Physicians must weigh the perceived risks and disadvantages of treating a histologically indeterminate tumor against the consequences of "under" treatment if the lesion is, in fact, biologically malignant.
