Squamous Cell Carcinoma of the Thumb: A Case Report.

Squamous cell carcinoma (SCC) is the most common tumor of the hand with a high tendency for local recurrence and a low rate of metastasis. Herein, we present an interesting case of SCC of the thumb of the right hand in a 68-year-old patient with one recurrence, treated with surgical excision and following radiotherapy. Five years postoperative, there are no clinical and imaging data for local recurrence, as well as the presence of metastases. We also make a brief review of the current literature on this neoplasia.

Normative Data of Handgrip Strength in Macedonian Children and Adolescents According to Chronological and Biological Age / Datos Normativos de la Fuerza de Prensión Manual en Niños y Adolescentes Macedonios Según la Edad Cronológica y Biológica

SUMMARY: The handgrip strength is used as a means of individual's health prediction during life. It is used as an indicator of the nutrition status, bone fragility, presence of sarcopenia and it correlates with certain diseases and clinical complications. The research goal was to analyze the results of the hand dynamometry test, based on the chronological and biological age, and to offer normative and referent standards about children and adolescents from the Republic of North Macedonia. The study was conducted on a sample of 4031 respondents of both sexes at the age 6-14 years. In order to achieve the research goals, the measured characteristics were of the weight, height, sitting height and handgrip strength. The body mass index and biological maturity values (APHV) were obtained by using formulas. On the basis of the obtained results, it can be concluded that statistically significant differences in handgrip strength are established between the boys and girls of all age categories. Also, statistically significant differences between boys and girls are established in the hand dynamometry test of all APHV levels. In general, the use of the APHV allows a better categorization of the performance of the studied children and adolescents. With boys, the correlation between the chronological age and test was 68 %, and with girls - 77 %. The normative referent standards of the hand dynamometry test are presented in percentiles for both sexes. Thye hand dynamometry test's results during childhood and adolescence should be analyzed and interpret on the basis of biological age, and not on the chronological age. These tools can help specialists who work with children and adolescents in ethnic and epidemiological context.

La fuerza de prensión se utiliza como medio para predecir la salud del individuo durante la vida. Se utiliza como indicador del estado nutricional, fragilidad ósea, presencia de sarcopenia y se correlaciona con determinadas enfermedades y complicaciones clínicas. El objetivo de la investigación fue analizar los resultados de la prueba de dinamometría manual, con base en la edad cronológica y biológica, y ofrecer estándares normativos y referentes sobre niños y adolescentes de la República de Macedonia del Norte. El estudio se realizó en una muestra de 4031 encuestados de ambos sexos con edades comprendidas entre 6 y 14 años. Para lograr los objetivos de la investigación, las características medidas fueron el peso, la altura, la altura al sentarse y la fuerza de prensión. El índice de masa corporal y los valores de madurez biológica (APHV) se obtuvieron mediante fórmulas. Sobre la base de los resultados obtenidos, se puede concluir que se establecen diferencias estadísticamente significativas en la fuerza de prensión manual entre niños y niñas de todas las categorías de edad. Asimismo, se establecen diferencias estadísticamente significativas entre niños y niñas en la prueba de dinamometría manual de todos los niveles APHV. En general, el uso del APHV permite una mejor categorización del desempeño de los niños y adolescentes estudiados. En los niños, la correlación entre la edad cronológica y la prueba fue del 68 %, y en las niñas, del 77 %. Los estándares normativos referentes de la prueba de dinamometría manual se presentan en percentiles para ambos sexos. Los resultados de la prueba de dinamometría manual durante la infancia y la adolescencia deben analizarse e interpretarse en función de la edad biológica y no de la edad cronológica. Estas herramientas pueden ayudar a los especialistas que trabajan con niños y adolescentes en un contexto étnico y epidemiológico.

Cardio-Physiological and Anthropometric Profile of Elite International Handball Players from Top Ranking Macedonian Teams / Perfil Cardiofisiológico y Antropométrico de Jugadores Internacionales de Balonmano de Élite de Equipos Macedonios de Primer Nivel

SUMMARY: Monitoring of body composition and cardiophysiological parameters are main part of the general health status of handball players and significant indicators of their physical fitness. The assessment of body components, especially skeletal muscle mass and body fat mass are important because of their influence on sport performance. The aim of this study is to determine the body composition and cardiophysiological characteristics of elite handball players from Republic of North Macedonia. 27 male HB players from two top ranking teams from RNM were tested ergometrically with Bruce protocol for determination of maximal oxygen consumption; body analysis was made with bioelectrical impedance analyzer, InBody 720. Anthropometric parameters were as follows: mean height was 190.4±7.8 cm and weight 96.3±15.5 kg, skeletal muscle mass (SMM)=47.11±6.69 kg; BMI=26.38±3.1; BF%=15.04±6.01 and WHR=0.9±1.8. The result of ergometrical test produce mean VO2 max=43.92 ml/kg/min which is 100.46 % of reference value. The body composition of elite international handball players from the top handball teams in Republic of North Macedonia showed similar body components as other European handball players. The obesity diagnose parameters were negatively associated with exercise time and maximal oxygen consumption.

El seguimiento de la composición corporal y los parámetros cardiofisiológicos son una parte principal del estado de salud general de los jugadores de balonmano y son indicadores importantes de su condición física. La evaluación de los componentes corporales, especialmente la masa muscular esquelética y la masa grasa corporal, son importantes debido a su influencia en el rendimiento deportivo. El objetivo de este estudio fue determinar la composición corporal y las características cardiofisiológicas de jugadores de balonmano de élite de la República de Macedonia del Norte. Se evaluaron 27 jugadores masculinos de HB de dos equipos de primer nivel de RNM ergométricamente con el protocolo de Bruce para determinar el consumo máximo de oxígeno; el análisis corporal se realizó con el analizador de impedancia bioeléctrica InBody 720. Los parámetros antropométricos fueron los siguientes: talla media 190,4±7,8 cm y peso 96,3±15,5 kg, masa músculo esquelética (SMM)=47,11±6,69 kg; IMC=26,38±3,1; %GC=15,04±6,01 y RCC=0,9±1,8. El resultado de la prueba ergométrica produce un VO2 máximo medio = 43,92 ml/kg/ min, que es el 100,46 % del valor de referencia. La composición corporal de los jugadores de balonmano internacionales de élite de los mejores equipos de balonmano de la República de Macedonia del Norte mostró componentes corporales similares a los de otros jugadores de balonmano europeos. Los parámetros diagnósticos de obesidad se asociaron negativamente con el tiempo de ejercicio y el consumo máximo de oxígeno.

A Rare Variation of the Levator Scapulae Muscle: A Case Report and Review of Literature.

Muscle variations in the posterior neck region are mainly categorized as variations in the origin and insertion of the muscles and the presence of accessory slips or rudimentary muscles. The levator scapulae muscle is a variable muscle with several different types of variations described throughout the literature. Herein, we report a rare unilateral case of an accessory slip from the levator scapulae. Aberrant muscle slip originates from the distal one-third of the levator scapulae. Then, it passes upwards and outwards above a vascular bundle containing a superficial branch of the transverse cervical artery and vein. The deviant muscle slip inserts onto the superior nuchal line. Muscle variations in the neck's posterior region and the levator scapulae's variations, as per se, have the utmost clinical significance since they might be mistaken for tumor mass. Moreover, such variations might be deceptive during surgical procedures in the region. Therefore, detailed knowledge of such complex muscular variations in the posterior region of the neck is paramount for surgeons and radiologists alike.

Symptomatic Bilateral Talonavicular Coalition in a Seven-Year-Old Boy.

Congenital talonavicular coalition is less frequent than the talocalcaneal or the calcaneonavicular and accounts for around 1% of all tarsal coalitions. Commonly, patients are asymptomatic and rarely need surgical treatment. Herein, we present a case of bilateral symptomatic talonavicular coalition in a seven-year-old boy who underwent surgery with full relief of symptoms. We also review the literature and discuss this pathological condition in detail.

Nerve to subclavius for neurotization procedures: an anatomical feasibility study.

Injuries to the inferior trunk of the brachial plexus and its components can be debilitating. As such injuries are prioritized by surgeons during repair, an additional nerve transfer is considered herein. In the supine position, 13 adult cadavers (26 sides) underwent dissection of the nerve to subclavius and the proximal brachial plexus in the supraclavicular region. Once the nerve was located and isolated from origin to termination, measurements of its length and diameter were made. Next, the C8 and T1 roots and inferior trunk were identified. The distal end of the nerve to subclavius was transected and swung to these roots and the inferior trunk. Once the nerves to subclavius were transposed and in a tension-free manner, the length of excess nerve following being brought to each of these nerves was measured. A nerve to subclavius was identified on all sides. The nerve originated from the superior trunk and traveled anterior to the middle and inferior trunks on all sides. The mean diameter of the nerve to subclavius was 0.8 mm, and the mean length was 57 mm. After cutting the nerve to subclavius at its entrance into the subclavius muscle, the distal nerve could be transferred tension free to the inferior trunk of the brachial plexus and T1 ventral ramus on all sides. The distal nerve to subclavius reached the T1 ventral ramus with an average of 18 mm of additional length and to the C8 ventral ramus with an average of 19 mm. The nerve also could be transferred to the inferior trunk of the brachial plexus with an average of 20 mm of additional length. The nerve to subclavius was found to have approximately 3000 axons. To our knowledge, use of the nerve to subclavius has previously not been used for nerve transfer procedures. Based on our cadaveric study, this often-overlooked nerve can be easily transposed to other regional nerves such as the inferior trunk of the brachial plexus.

Rare inflammatory myofibroblastic tumor of the urinary bladder.

An inflammatory myofibroblastic tumor of the urinary bladder (IMTUB) is a rare tumor. The most common localization is in the lung and visceral adipose tissue. Histologically, it is represented by myofibroblasts, inflammatory cells and leukocytes.

Variant origin of the right coronary artery from the left main coronary artery together with aortic valve stenosis: report of a rare case / Origen variante de la arteria coronaria derecha a partir de la arteria coronaria izquierda junto con estenosis de la valva aórtica: reporte de un caso raro

SUMMARY: Variations in the origin of the right coronary artery have an incidence between 0.09 % and 0.92 %. Herein, we report a rare case of a coronary artery anomaly in which the right coronary artery originates from the left main coronary artery. This variant was found during routine coronarography, combined with an artificial aortic valve. Despite their rare occurrence, some variations in the origins of the coronary arteries can be life threatening and are associated with a higher risk of sudden cardiac death. They can also pose serious technical challenges and predispose to complications during coronary angiographic procedures. Thus, knowledge of such anomalies is paramount for managing the patients correctly.

Las variaciones en el origen de la arteria coronaria derecha tienen una incidencia entre el 0,09 % y el 0,92 %. En este documento, informamos un caso raro de una anomalía de la arteria coronaria en la que la arteria coronaria derecha se originaba en la arteria coronaria izquierda. Esta variante se encontró durante una coronariografía de rutina, combinada con una válvula aórtica artificial. A pesar de su rara aparición, algunas variaciones en los orígenes de las arterias coronarias pueden poner en peligro la vida y se asocian con un mayor riesgo de muerte súbita cardíaca. También pueden plantear serios desafíos técnicos y predisponer a complicaciones durante los procedimientos angiográficos coronarios. Por tanto, el conocimiento de dichas anomalías es fundamental para el manejo correcto de los pacientes.

Chondroblastoma Affecting the Apophysis of the Greater Trochanter in a Child.

Chondroblastomas are rare primary bone tumours typically affecting the epiphyses and less frequently the apophyses of the growing skeleton. Most cases are treated by intralesional curettage with or without local adjuvants and this technique can produce good long-term outcomes. Herein, we describe a case of chondroblastoma of the greater trochanter in a 12-year-old male child that was treated by intralesional curettage and grafting with calcium phosphate bone cement (Neocement Inject® P, Bioceramed, Loures, Portugal). A brief review of the literature is also presented.

Patella cubiti - a continuing etiological mystery / Patella cubiti: un misterio etiológico continuo

SUMMARY: A sesamoid bone in the elbow joint is a rare anatomical variation described as a Patella cubiti. Although this variation has been known for centuries its exact etiology is still unclear. Congenital, developmental, and traumatic hypotheses have been proposed. It seldom causes clinical manifestations than elbow stiffness or hypomobility. Herein, we present a case of a 31-year-old patient admitted to our department with complaints of swelling and erythema in the right elbow. An X-ray image revealed a triangular accessory bone with rounded edges, which was diagnosed as a Patella cubiti in combination with olecranon bursitis. Knowledge of this rare elbow abnormality is paramount for orthopedic surgeons and roentgenologists in their daily medical practice.

Un hueso sesamoideo en la articulación del codo es una rara variación anatómica descrita como Patella cubiti. Aunque esta variación se conoce desde hace siglos, su etiología exacta aún no está clara. Se han propuesto hipótesis congénitas, de desarrollo y traumáticas. Rara vez causa manifestaciones clínicas que no sean rigidez o hipomovilidad del codo. Presentamos el caso de un paciente de 31 años que ingresó en nuestro servicio por presentar tumefacción y eritema en el codo derecho. Una imagen de rayos X reveló un hueso accesorio triangular con márgenes redondeados, que se diagnosticó como una Patella cubiti en combinación con bursitis del olécranon. El conocimiento de esta rara anomalía del codo es fundamental para los cirujanos ortopédicos y los médicos radiólogos en su práctica médica diaria.

Comparative Evaluation of the Diagnostic Value of Procalcitonin and hsCRP for the Presence of Mild-to-Moderate Diabetic Foot Infections.

The aim of this study is to compare the efficacy of procalcitonin (PCT) and high-sensitive C-reactive protein (hsCRP) as diagnostic biomarkers in patients with diabetes and mild-to-moderate diabetic foot infections. A total of 119 patients (102 with type 2 diabetes and 17 with type 1 diabetes), of mean age 60.29 ± 10.05 years, divided into 3 groups-diabetic foot ulcer (DFU) with active infection (IDFU group, n = 41), DFU without clinical signs of infection (non-IDFU group, n = 35), and a control group with diabetes without DFU (n = 43). Infection severity was graded according to the International Working Group on the Diabetic Foot guideline-non-IDFU group as Grade 1, IDFU group as Grade 2 (n = 22), and Grade 3 (n = 19). Serum hsCRP was assessed by the immunoturbidimetric method and PCT by the enzyme chemiluminescence immunoassay (ECLIA) method. Levels of white blood cells (WBC) were assessed using the Medonic hematology analyzer and erythrocyte sedimentation rate (ESR) by the Westergren method. Serum hsCRP, WBC count, and ESR were significantly higher in the IDFU group as compared to non-IDFU and control groups, whereas PCT levels did not differ between the groups. hsCRP presented with higher sensitivity (80%), specificity (79%), area under the curve (AUC) 0.856, in comparison to PCT (sensitivity 63%, specificity 62%, AUC 0.617) for the presence of IDFU, as well as in the Grade 3 subgroup (84% sensitivity and specificity, AUC 0.911). The combined model of both markers did not present with better accuracy than using hsCRP alone. In conclusion, hsCRP appears to be a better diagnostic biomarker than PCT in the diagnosis of moderate foot ulcer infection. Both markers fail to distinguish mild infection.

Cross-Over Pathogenic Bacteria Detected in Infected Tomatoes (Solanum lycopersicum L.) and Peppers (Capsicum annuum L.) in Bulgaria.

The ability of certain human pathogens to adapt to plants without losing their virulence toward people is a major concern today. Thus, the aim of the present work was the investigation of the presence of cross-over pathogenic bacteria in infected tomato and pepper plants. The objects of the study were 21 samples from seven different parts of the plants and three from tomato rhizosphere. In total, 26 strains were isolated, identified by MALDI-TOF, and phenotypically characterized. The PCR amplification of the rpoB gene was applied as an approach for the rapid detection of cross-over pathogens in plant samples. A great bacterial diversity was revealed from tomato samples as nine species were identified (Leclercia adecarboxylata, Pseudesherichia vulneris, Enterobacter cancerogenus, Enterobacter cloacae, Enterobacter bugandensis, Acinetobacter calcoaceticus, Pantoea agglomerans, Pantoea ananatis, and Pectobacterium carotovorum). Polymicrobial contaminations were observed in samples T2 (tomato flower) and T10 (tomato fruit). Five species were identified from pepper samples (P. agglomerans, L. adecarboxylata, Pseudomonas sp., Pseudomonas putida, and Enterococcus sp.). Antibiotic resistance patterns were assigned in accordance with EFSA recommendations. All isolates showed varying resistance to the tested antibiotics. The genetic basis for the phenotypic antibiotic resistance was not revealed. No genes for the virulence factors were found among the population. To our knowledge, this is the first overall investigation of tomato and pepper cross-over pathogenic bacterial populations in Bulgaria.

A comparative study of the epiligament of the medial collateral and anterior cruciate ligaments in the human knee: Immunohistochemical analysis of CD 34, α-smooth muscle actin and vascular endothelial growth factor in relation to epiligament theory.

BACKGROUND: This study evaluated and compared the expression of VEGF, CD34, and α-SMA in the anterior cruciate ligaments and medial collateral ligaments in healthy human knees in order to enrich the epiligament theory regarding ligament healing after injury. METHODS: Samples from the mid-substance of the anterior cruciate ligament and the medial collateral ligament of 12 fresh knee joints were used. Monoclonal antibodies against CD34, α-SMA, and VEGF were used for immunohistochemical analysis. Photomicrographs were analyzed using the ImageJ software. RESULTS: The epiligament of the anterior cruciate ligament showed slightly higher expression of CD34, α-SMA, and VEGF than the epiligament of the medial collateral ligament. Overall, among the tested markers, α-SMA expression was most pronounced in anterior cruciate ligament epiligament images and CD34 dominated in medial collateral ligament epiligament images. The intensity of DAB staining for CD34, α-SMA, and VEGF was higher in vascular areas of the epiligament than in epiligament connective tissue. CONCLUSIONS: The results illustrate that CD34, α-SMA, and VEGF are expressed in the human epiligament. The differences between the epiligament of the investigated ligaments and the fact that CD34, α-SMA, and VEGF, which are known to have a definite role in ligament healing, are predominantly expressed in the main vascular part of the ligament-epiligament complex enlarge the existing epiligament theory. Future investigations regarding better ligament healing should not overlook the epiligament tissue.

Lateral epicondylitis: New trends and challenges in treatment.

Lateral epicondylitis (LE) is a chronic aseptic inflammatory condition caused by repetitive microtrauma and excessive overload of the extensor carpi radialis brevis muscle. This is the most common cause of musculoskeletal pain syndrome in the elbow, inducing significant pain and limitation of the function of the upper limb. It affects approximately 1-3% of the population and is frequently seen in racquet sports and sports associated with functional overload of the elbow, such as tennis, squash, gymnastics, acrobatics, fitness, and weight lifting. Typewriters, artists, musicians, electricians, mechanics, and other professions requiring frequent repetitive movements in the elbow and wrists are also affected. LE is a leading causation for absence from work and lower sport results in athletes. The treatment includes a variety of conservative measures, but if those fail, surgery is indicated. This review summarizes the knowledge about this disease, focusing on risk factors, expected course, prognosis, and conservative and surgical treatment approaches.

Three ipsilateral paracondylar processes with other skull base variations: case report.

Variations of the skull base can affect surgical approaches and must be considered when viewing and interpreting radiological imaging. Here, we report a unique collection of bony anatomical variations found on a single adult skull. Three bony excrescences from the occipital bone were identified in the paracondylar region. The smallest of these processes was 7 mm long and was just medial to the mastoid process of the temporal bone and posterior to the styloid process. One bony process was attached to the occipital condyle and was 12 mm in length. The longest of these processes was 17 mm long and arose from the jugular process of the occipital bone. Paracondylar processes can be symptomatic. Knowledge of the bony variations at the skull base is important to those who operate in this region or review and interpret radiological imaging.

Surface Chemistry Study of the Interactions of Sesame Oil with Meibomian Films.

A possible approach for the treatment of meibomian gland disease (MGD) can be the supplementation of meibomian gland secretion (MGS) with nonpolar lipids (NPL) rich plant oils. Sesame oil (SO), approximately equal in monounsaturated fat (oleic acid, 40% of total) and polyunsaturated fat (linoleic acid, 42% of total), has shown multiple health benefits due to its anti-inflammatory and antioxidant effects. Thus, the interactions between SO and MGS in surface layers deserve further study. Therefore, pseudobinary films were formed with controlled MGS/SO molar ratios (0%, 10%, 30%, 50%, and 100% SO) at the air/water surface of the Langmuir trough over phosphate buffered saline (pH 7.4) subphase. Surface pressure (π)-area (A) isotherms and Brewster angle microscopy observations showed nonideal interactions where SO aggregates with MGS and complements the NPL stratum of the meibomian layers. The analysis of stress relaxation transients with Kohlrausch-Williams-Watts equation revealed that the supplementation of fixed amount of MGS with excess lipids via SO altered the dilatational elasticity of the films as reflected by the increase of the exponent ß. Thus, SO with its unique combination of high oxidative stability and abundance of long polyunsaturated acyl chains might be a useful supplement to MGS layers.

L3 rootlet recurrent melanocytic schwannoma - case report and literature review.

First described by Miller in 1932, melanocytic schwannoma (MS) (melanotic schwannoma, pigmented schwannoma) is a rare variation of peripheral nerve sheet tumours with ectodermal origin occurring predominantly in somatic, but also in the autonomic peripheral system with around two hundred cases in the literature. Predominantly benign tumours, MS are still imaging and pathological challenge and can be easily misdiagnosed with more aggressive peripheral nerve tumours.We report a case of melanocytic schwannoma on L3 sensory rootlet with systematic literature review of nearly 200 cases presented in intracranial, paraspinal region, thoracic, abdominal or pelvic cavities and skin. Two-thirds of cases are part of Carney complex.We present a case of a 61-year-old male with a 3-month history of low back pain, progressive numbness and stiffness in the right thigh, shin and knee, tibial and peroneal paresis causing gait disturbance and neurological claudication. MRI findings present "sand clock" type intradural extramedullary tumour formation with extension to the L3 rootlet through right L3-L4 foramen, hypointense on T2 and hyperintense on T1. Pathological diagnosis of sporadic type melanocytic schwannoma was made via immunohistological and ultrastructural analysis. Thirteen months after total resection there was clinical and MRI evidence of recurrence of the tumour. Total resection and radiosurgery was performed with a recurrence free period of 14 months.A gold standard for melanocytic schwannoma treatment is gross total surgical resection. Despite being considered benign tumours, MS have a local or metastatic recurrence of around 13%. MRI imaging in most of the cases is insufficient and only exhaustive pathological and immunohistological examination is the key to diagnosis. Need of postoperative radiation therapy is still controversial. For the first time, a criterion for postoperative adjuvant therapy was established.
