ABSTRACT

Resumen Las vasculitis leucocitoclásticas se definen como el daño e inflamación de las paredes vasculares, son aquellas vasculitis de pequeños vasos que anatomopatológicamente presentan leucocitoclasia y puede observarse como una manifestación extraintestinal de la enfermedad inflamatoria intestinal. En la colitis ulcerativa se presentan en menor frecuencia, por inmunocomplejos generados en la mucosa intestinal debido a la exposición del tejido linfoide submucoso a antígenos fecales; podrían precipitarse en las paredes de los pequeños vasos. Se pueden asociar con Clostridium difficile, que es un bacilo grampositivo esporulado, anaerobio estricto, que se encuentra normalmente en el medio ambiente y produce colitis, que se manifiesta como un cuadro diarreico presentado después de la ingesta de antibióticos y altera la flora bacteriana común de este órgano. El caso se trata de un paciente 36 años de edad con cuadro de diarreas líquidas con moco y escaso sangrado; se realizó un estudio endoscópico y anatomopatológico en el que se observó colitis ulcerativa con coproparasitario positivo para antígeno de C. difficile, y en su hospitalización presentó lesiones dérmicas petequiales y necróticas en el cuarto dedo de la mano izquierda, que en la biopsia dio como resultado vasculitis de pequeños vasos. En este artículo se revisan de forma práctica los aspectos relacionados con la fisiopatología, histología, tratamiento y diagnósticos de la manifestación extraintestinal dermatológica rara, como la vasculitis leucocitoclástica en pacientes con colitis ulcerativas asociadas con Clostridium.


Abstract Leukocytoclastic vasculitis is defined as the damage and inflammation of the vascular walls. The term refers to vasculitis of the small vessels that anatomopathologically present leukocytoclasia and it can be seen as an extra-intestinal manifestation of inflammatory bowel disease. In ulcerative colitis, it occurs less frequently due to immune complexes produced in the intestinal mucosa by exposure of the submucosal lymphoid tissue to fecal antigens, which could precipitate in the walls of the small vessels. This condition can be associated with Clostridium difficile, which is a gram-positive, sporulated, strict anaerobic bacillus, normally found in the environment. It causes colitis that manifests as a diarrheal disease following the ingestion of antibiotics that alter the common bacterial flora of this organ. This is the case report of a 36-year-old patient with liquid diarrhea with mucus and scarce bleeding. Endoscopic and anatomopathological studies were performed, finding ulcerative colitis with positive coproparasite for Clostridium difficile antigen. The patient was hospitalized, and during his stay, he presented with petechiae and necrotic skin lesions on the fourth finger of the left hand. Skin biopsy showed small vessel vasculitis. This article is a practical review of the pathophysiology, histology, treatment, and diagnosis of a rare dermatologic extraintestinal manifestation, namely, leukocytoclastic vasculitis, in patients with C. difficile-associated ulcerative colitis.

ABSTRACT

El síndrome de Achenbach es un cuadro de baja incidencia y de etiología idiopática. Se caracteriza por la aparición aguda de coloración azul digital sin un episodio desencadenante, imitando a un cuadro isquémico, pero, al contrario, el síndrome de Achenbach se autolimita sin dejar secuelas. Se presenta una mujer de 75 años que consultó en la central de emergencias por dolor y cambio de coloración violácea del dedo índice de su mano derecha, de inicio súbito. Los estudios complementarios no aportaron información relevante. Se administró un tratamiento sintomático y se logró la resolución completa del cuadro. La anamnesis y el examen físico exhaustivo tienen un rol fundamental para sospechar este cuadro y los estudios complementarios se reservan para descartar otras enfermedades, si es necesario. Consideramos que conocer esta enfermedad y un abordaje correcto conducen a un diagnóstico apropiado. Nivel de Evidencia: IV


Achenbach's Syndrome (AS) is a pathology with low incidence and its etiology is unknown. It is characterized by the acute appearance of blue coloration in the finger without a triggering event and might be confused with an ischemic event. However, AS is a self-limited disease without sequelae. This case report is about a 75-year-old woman who presented sudden onset pain and purple coloration in the index finger of her right hand. Diagnostic tests were unhelpful and did not provide relevant information. She received symptomatic treatment, achieving complete resolution. The anamnesis and an exhaustive physical examination play a primary role in the suspicion; leaving diagnostic tests for the exclusion of other pathologies when they are required. We believe that knowing about this pathology allows a correct approach leading to an appropriate diagnosis. Level of Evidence: IV

ABSTRACT

Se presenta el caso de un hombre de 27 años con una lesión grave articular interfalángica proximal en el dedo anular de la mano derecha, provocada por un proyectil de arma de fuego, que fue tratada con doble injerto osteocondral de costilla. Tenía una fractura expuesta y déficit de stock óseo y cartilaginoso tanto en la primera como en la segunda falange. Luego de la limpieza inicial, a las 3 semanas, se realizó una artroplastia interfalángica proximal con doble injerto osteocondral de costilla y fijador externo distractor de Suzuki. Se describe con detalle la técnica quirúrgica.A las 10 semanas posoperatorias, la flexión activa interfalángica era de 75° y la extensión activa, de -15°, con articulación estable. Alta laboral a los 3 meses de la cirugía, sin dolor y un puntaje DASH de 14,2. Las radiografías mostraron la incorporación de los injertos, sin reabsorción y con una articulación congruente.Se valora la ventaja de esta técnica en cuanto a la escasa morbilidad para la zona dadora y la versatilidad para las reconstrucciones con defectos articulares. El resultado funcional temprano subjetivo y objetivo fue satisfactorio. No se pueden descartar complicaciones futuras. Nivel de Evidencia; IV


We present the case of a 27-year-old male patient with a gunshot wound and severe proximal interphalangeal joint injury in the ring finger of the right hand, treated with a double osteochondral rib graft. He had an exposed fracture and a lack of bone and cartilage stock in both the first and second phalanx. After the initial toilette, at 3 weeks, a proximal interphalangeal arthroplasty was performed with a double osteochondral rib graft protected by a Suzuki external distractor. The surgical technique is described in detail. At 10 weeks after surgery, an active interphalangeal joint flexion of 75° and active extension of -15° were verified, without articular instability. The patient returned to work at 3 months after surgery, with no residual pain (0 VAS score) and a DASH score of 14.2. Radiographs showed incorporated grafts without resorption and a congruent joint. This technique is valued for its low morbidity on the donor site and versatility for joint defect reconstructions. The limitations of our study are mentioned. The clinical case presented obtained a satisfactory subjective and objective early functional outcome. Further complications cannot be ruled out. Level of Evidence: IV

ABSTRACT

Abstract Objectives To evaluate the prevalence of absence of flexor digitorum superficialis muscle tendons function of the fourth and fifth fingers of the hand in the Brazilian population Methods Prospective study performed at the orthopedics and traumatology department of a university hospital. The study was conducted from October 2017 to April 2018. The sample consisted of volunteers with no history of upper limb trauma, surgery or any other condition. This study included both male and female individuals over 18 years old. The flexor digitorum superficialis muscle tendons of the fourth and fifth fingers were evaluated through clinical tests by three independent examiners. The data were analyzed using GraphPad Prism 5.0 (GraphPad Software, San Diego, CA, USA). Results A total of 2,016 hands from 1,008 volunteers were analyzed. The prevalence of absence of flexor digitorum superficialis muscle tendon function of the fourth finger was 0.56% at the right hand and 0.99% at the left hand. At the right hand, this prevalence was higher in females compared to males (p= 0.0328). No difference between genders was noted in the left hand (p= 0.7562). The prevalence of absence of flexor digitorum superficialis muscle tendon function of the fifth finger was 34.53% in the right hand and 30.06% in the left hand. This prevalence was higher in females compared to males, both at the right hand (p= 0.0001) and the left hand (p= 0.0003). Conclusion Even though there are studies performed separately in different ethnic groups, there were no data in the literature regarding the prevalence of absence of flexor digitorum superficialis muscle tendons function of the fourth and fifth fingers of the hand in a multiethnic population such as the Brazilian one.

Métodos Estudo prospectivo foi realizado no departamento de ortopedia e traumatologia de um hospital universitário. O estudo foi desenvolvido no período de outubro de 2017 a abril 2018. A amostra foi formada por voluntários sem histórico de trauma, cirurgia ou qualquer afecção dos membros superiores. Foram incluídos neste estudo indivíduos de ambos os gêneros com idade igual ou superior a 18 anos. A avaliação da função do tendão do múculo flexor superficial do quarto e quinto dedos foi realizada por meio de testes clínicos por três examinadores independentes. Para análise dos dados foi utilizado o programa GraphPad Prism 5.0 (GraphPad Software, San Diego, CA, EUA). Resultados Foram analisados 1.008 voluntários totalizando 2.016 mãos. A prevalência da ausência de função do tendão do músculo flexor superficial do quarto dedo foi de 0,56% na mão direita e 0,99% na mão esquerda. Em relação ao gênero, foi verificado na mão direita uma maior prevalência da ausência de função do flexor superficial do quarto dedo no gênero feminino quando comparado ao masculino (p= 0,0328). Na mão esquerda não foi observada diferença entre os gêneros (p= 0,7562). A ausência de função do músculo flexor superficial no quinto dedo foi de 34,53% na mão direita e de 30,06% na mão esquerda. Quando analisamos o quinto dedo em relação aos gêneros, foi verificado que a prevalência da ausência de função do músculo flexor superficial foi mais frequente no gênero feminino que no masculino, tanto na mão direita (p= 0.0001) como na mão esquerda (p= 0.0003). Conclusão Apesar de haver estudos realizados separadamente em diversas etnias, não havia na literatura dados referentes à prevalência da ausência de função do músculo flexor superficial do quarto e quinto dedos da mão em uma população miscigenada como a brasileira.

ABSTRACT

ABSTRACT Played all over the world, golf has gained popularity, for it is a sport that depends on individual abilities. For this reason the search for tools that aim to seek and guide its respective talented players has become very important. Therefore, this study had the objective of comparing the distribution of the dermatoglyphic indicators of high performance golfers and of a group control of non-athletes. The sample was composed of 46 individuals with paired age and gender, divided into two groups: the Group Golf (GG), composed of 23 golfers, and the Group Control (GC), composed of 23 individuals control randomly selected. The golfers, part of the Project Golf Brazil of the Brazilian Golf Confederation, were between 11 and 21 years old. The results demonstrated that the number of lines in the pattern was of six possible variables of fingerprint (MESQL1, MESQL2, MESQL4, MESQL5, SQTLE, SQTL) is significantly higher in the golfers (GG) when compared to the group control (GC). When observed the qualitative variables, i. e., the pattern type, significant diferences where observed between the groups, since the golfers (GG) presented more Radial Loops (RL) in MDT5 when compared to the group control (GC). The results found in this study demonstrated that the dermatoglyphic profile of high performance golfers differ from the non-athlete population.


RESUMO Jogado em todo o mundo, o golfe está ganhando popularidade, sendo um esporte que depende das habilidades individuais, tornando-se importante a busca por ferramentas que visem buscar e orientar seus respectivos talentos. O presente estudo teve por objetivo comparar a distribuição dos indicadores dermatoglíficos de golfistas de alto rendimento e de um grupo controle de não atletas. A amostra foi composta por 46 indivíduos com idade e sexo pareados, divididos em dois grupos: o Grupo Golf (GG), composto por 23 golfistas e o Grupo Controle (GC), composto por 23 indivíduos controle aleatoriamente selecionados. Os golfistas, parte do Projeto Golf Brasil da Confederação Brasileira de Golfe, tinham idade entre 11 e 21 anos. Os resultados demonstram que o número de linhas no padrão de seis possíveis variáveis de impressão digital (MESQL1, MESQL2, MESQL4, MESQL5, SQTLE, SQTL) é maior nos golfistas (GG) quando comparado ao grupo controle (GC). Quando observadas as variáveis qualitativas, ou seja, o tipo de figura, observaram-se diferenças significativas entre os grupos, visto que os Golfistas (GG) apresentaram maior quantidade de Presilha Radial (LR) no MDT5 quando comparados ao grupo controle (GC). Os resultados encontrados neste estudo demonstraram que o perfil dermatoglífico de golfistas de alto rendimento difere da população não atleta.

ABSTRACT

Solitary fibrous tumor (SFT) is a relatively uncommon mesenchymal neoplasm that usually arises in the pleura, but also has been reported in numerous extrapleural locations, including cutaneous site. The skin lesion presents as a circumscribed nodule or tumor, mainly on the head and neck. A 41-year-old male presented with 6 months history of nail lesion without symptom on the left third finger. The lesion is slightly yellowish discoloration with subungual erythematous nodule and distal onycholysis. Biopsy specimen from the nail lesion showed the spindle cells form patternless pattern with hypercellular and hypocellular area. And small blood vessels and dilated vascular spaces were present. The result of special stain for specimen showed that positive for CD34, Bcl-2, and CD99 but negative for S-100, FactorXIIIa, and smooth muscle action. Recognition of this uncommon location of SFT is important because of possible confusion with other subungual tumors, including glomus tumor, fibroma and other fibrohistiocytic tumors like dermatofibrosarcoma protuberans, superficial acral fibromyxoma and cellular digital fibroma. Here in, we report a case of SFT of subungual region. We think this case is interesting because of uncommon location and may be helpful to more understand the character of this disease.

ABSTRACT

This paper discusses the short-term memory of vibro-tactile perception of human fingertips. By using a self-developed vibro-tactile expression device, a recall experiment was firstly carried out among 20 subjects aged 20-30 (10 males and 10 females) to discover the memory span about the vibro-tactile perception of human fingertips. Within this memory span, a cognitive experiment analyzing the recognition accuracy and the reaction time was carried out. The results showed: (1) The vibro-tactile memory span of human fingertip is 4 ± 1; (2) The vibro-tactile memory span increases as the discrete intensity between vibration stimuli increases; (3) Too long or too short vibration duration will reduce the vibro-tactile memory span, and the optimal vibration duration for men is 400 ms, for women is 300 ms; (4) The more the number of vibration stimuli is perceived by the human fingertip, the lower the recognition accuracy and the longer the reaction time it needs; (5) Compared with the vibration stimuli in disorder, people are more likely to remember the vibration stimuli in increasing/decreasing order; (6) The information extraction mechanism of the short-term memory about fingertip vibro-tactile perception bases a point to point scanning process among these stimuli. These results help to understand the human fingertip tactile characteristics and provide a physiological basis for the study of tactile feedback technologies.

ABSTRACT

PURPOSE: To characterize associated reactions (ARs) in the contralateral arm across multiple muscles during unimanual tasks and to identify factors related to ARs in children with cerebral palsy (CP).MATERIALS AND METHODS: This was a prospective, cross-sectional study of 35 children with CP. The extent of ARs of the contra-lateral, non-task hand was assessed while performing three unimanual tasks (opening and clenching the fist, a finger opposition task, and tapping fingers). The occurrence of ARs in each trial was evaluated separately for each task using a four-point scale (total scores ranged from 0 to 12). Surface electromyography (SEMG) was used to measure the firing activity of the muscles of the opposite arm during the task. The Manual Ability Classification System and Melbourne Assessment 2 (MA-2) were used to evaluate upper limb function.RESULTS: AR scores were higher in the more-affected limb than in the less-affected limb. SEMG data on the non-task hand showed motor overflow up to the elbow muscles in the more-affected limb. Root mean square ratios of EMG signals were significantly higher in children with ARs than in children without ARs. Multiple regression analysis showed both age and MA-2 to be significant factors related to ARs in the more-affected limb.CONCLUSION: Children with visible ARs showed motor overflow in the non-task limb during unimanual hand tasks. Age and upper limb function were significantly related to the extent of ARs in the more-affected limb of children with CP.

ABSTRACT

PURPOSE: To report a patient with asteroid hyalosis, which induced reduction of the visual acuity after cataract surgery.CASE SUMMARY: A 79-year-old female with no ophthalmic history visited our clinic with decreased vision. Her best-corrected visual acuity in both eyes was 20/100 in the right eye and 20/60 in the left eye. She had senile cataract in both eyes, and asteroid hyalosis in the left eye. After cataract surgery, her visual acuity in the left eye decreased to finger count. There were no specific findings that could have caused the visual disturbance, except dense asteroid bodies on fundus examination. After removal of the asteroid bodies by vitrectomy, the best-corrected visual acuity of the left eye recovered to 20/20.CONCLUSIONS: In patients with asteroid hyalosis, it is possible that decreased vision may be affected by changes of asteroid body properties in the vitreous gel after cataract surgery. The vision should improve after vitreous surgery.

ABSTRACT

The 2D:4D is thought as a biomarker for prenatal androgen exposure. Some studies have reported a significant difference between the sexes. Earlier studies reported variations in different ethnic and geographic groups. 2D:4D is related to several medical conditions including cardiovascular diseases (CVD) and metabolic syndrome (MetS). The present study investigated the relationships between hand preference, ratio of the index finger (2nd digit: 2D) and ring finger (4th digit: 4D) lengths (2D:4D), height, waist-to-height ratio (WHtR), waist circumference (WC) and weight, body mass index (BMI) in a Turkish population. The study comprised 118 healthy subjects (68 males and 50 females). 2D and 4D finger lengths and some anthropometric traits (height, weight, WC) were measured. The BMI and WHtR were calculated. Hand preference was determined by using a questionnaire (Edinburgh handedness inventory). Geschwind scores were calculated to evaluate the degree of hand preference. The mean age was 26.74 (female 27.86, male 25.89). The right hand 2D:4D was found significantly lower in males (0.9797) than in females (0.9922) (p< 0.001), but the left hand 2D:4D was insignificant. Significant correlations (negative) were observed between the 2D:4D (both left and right) and WHtR; the 2D:4D ratio (both left and right) and WC in males. However, in females, these correlations were insignificant. The R2D:4D was sexually dimorphic in a Turkish population. There were significant differences between strong right (SR) and weak left (WL) in terms of the R2D:4D. However only 5 subject's hand preference was found WL. Therefore, further studies are needed to determine the relationships between hand preference and R2D:4D in Turkish population. Further studies are needed to determine whether a larger sample population alters these possible associations between the ratio of 2D:4D and other investigated traits in a Turkish population.


El 2D:4D está pensado como un biomarcador para la exposición prenatal de andrógenos. Algunos estudios han reportado una diferencia significativa entre sexos. Estudios anteriores informaron variaciones en diferentes grupos étnicos y geográficos. 2D:4D está relacionado con varias afecciones médicas que incluyen enfermedades cardiovasculares (ECV) y síndrome metabólico (MetS). El presente estudio investigó las relaciones entre la preferencia de la mano, la proporción del dedo índice (2º dígito: 2D) y el dedo anular (4º dígito: 4D), longitudes (2D:4D), altura, relación cintura-altura (WHtR), circunferencia de cintura y peso (WC), e índice de masa corporal (IMC), en una población de Turquía. El estudio incluyó 118 sujetos sanos (68 hombres y 50 mujeres). Se midieron longitudes de dedos 2D y 4D y algunos rasgos antropométricos (altura, peso, WC). Se calcularon el IMC y el WHtR. La preferencia de la mano se determinó mediante el uso de una escala (Edinburgh Handedness Inventory). Las puntuaciones de Geschwind se calcularon para evaluar el grado de preferencia de la mano. La edad media fue de 26,74 años (femenino 27,86; masculino 25,89). La mano derecha 2D: 4D se encontró significativamente más baja en los hombres (0,9797) que en las mujeres (0,9922) (p <0,001), pero la mano izquierda 2D: 4D fue no significante. Se observaron correlaciones significativas (negativas) entre la 2D: 4D (izquierda y derecha) y WHtR y la relación 2D: 4D (izquierda y derecha) y WC en hombres. Sin embargo, en las mujeres, estas correlaciones fueron no significantes. El R2D: 4D fue sexualmente dimorfo en una población de Turquía. Hubo diferencias significativas entre la mano derecha fuerte (SR) y la mano izquierda débil (WL) en términos de R2D: 4D. Sin embargo, sólo se encontraron 5 preferencias de mano en el sujeto con WL. Por lo tanto, se necesitan más estudios para determinar las relaciones entre la preferencia de mano y R2D: 4D en la población de Turquía. Se necesitan más estudios para determinar si una muestra mayor altera estas posibles asociaciones entre la proporción de 2D: 4D y otros rasgos investigados en una población de Turquía.

ABSTRACT

The alteration of the vertical dimension can deteriorate the facial harmony, and it can be measured through objective and subjective methods, although many of which are not reliable. Objective: Relate the anthropometric fingers length with the measurement of the vertical occlusal dimension (VOD). Material and Methods: Cross-sectional, observational study that included 114 students from the School of Dentistry with class I malocclusion and complete dentition. The VOD was evaluated as the measurement between the subnasal points and the mental point; anthropometric measures included the length of the fingers (from the most mesial fold to the most distal edge) and the distance projected between the thumb and the index finger. Results: The average VOD was 64.03±5.15mm. A correlation was found between the VOD and the index finger length (p<0.01, r=0.29), between the VOD and middle finger length (p<0.01, r=0.31) and correlation between the VOD and the length of the little finger (p<0.05, r=0.23). No correlation was found between the VOD and the ring finger lengths (p= 0.051) or thumb (p=0.12). Conclusions: The anthropometric measurements of the index finger, middle finger, little finger and the projection of the thumb on the index finger correlated with the length of the vertical occlusal dimension.


La alteración de la dimensión vertical puede deteriorar la armonía facial, su medición puede realizar a través de métodos objetivos y subjetivos; sin embargo muchos de ellos no son confiables. Objetivo: Relacionar las longitudes antropométricas de los dedos de la mano con la medida de la dimensión vertical oclusal (DVO). Material y Métodos: Estudio transversal, observacional que incluyó a 114 estudiantes de la Facultad de Odontología con maloclusión de clase I y dentición completa. La DVO fue evaluada como la medida entre los puntos subnasal al punto mentoniano; las medidas antropométricas incluyeron a la longitud de los dedos (desde su pliegue más mesial hasta su borde más distal) y la distancia proyectada entre el pulgar al índice. Resultados: La DVO promedio fue de 64,03±5,15mm. Se encontró correlación entre la DVO y la longitud del dedo índice (p<0,01; r=0,29), entre la DVO y la longitud del dedo medio (p<0,01; r=0,31) y correlación entre la DVO y la longitud del dedo meñique (p<0,05; r=0,23). No se encontró correlación entre la DVO y las longitudes de los dedos anular (p=0,051) y pulgar (p=0,12). Conclusiones: Las medidas antropométricas del dedo índice, medio, meñique y la proyección del dedo pulgar sobre el dedo índice se correlacionaron con la longitud de la dimensión vertical oclusal.

ABSTRACT

Abstract Objective The purpose of this anatomical study was to analyze the possibility of transferring radial nerve branches to the supinator muscle to reinnervate the posterior interosseous nerve (PIN) originating from the C7-T1 roots. Methods Thirty members of 15 cadavers, all male, prepared with an intra-arterial glycerol and formaldehyde solution injection, were dissected. Results All dissected limbs presented at least one branch intended for the superficial and the deep heads of the supinatormuscle. These branches originated fromthe PIN. A branch to the supinator muscle, proximal to the arcade of Frohse, was identified in six members. In addition, 2 and 3 branches to the supinator muscle were found in 11 and 4 members, respectively. In two limbs, only one branch detached from the PIN, but it duplicated itself proximal to the arcade of Frohse. Seven limbs had no branches to the supinatormuscle at the region proximal to the arcade of Frohse. The branches destined for the supinator muscle were sectioned at the neuromuscular junction for connection with no tension to the PIN. The combined diameter of the branches for the supinator muscle corresponded, on average, to 53.5% of the PIN diameter. Conclusion The radial nerve branches intended for the supinator muscle can be transferred, with no tension, directly to the PIN to restore thumb and finger extension in patients with C7-T1 brachial plexus lesions.


Resumo Objetivo O objetivo deste estudo anatômico, foi analisar a possibilidade de transferir os ramos do nervo radial destinados ao músculo supinador para reinervar o nervo interósseo posterior (NIP), que se origina das raízes C7-T1. Métodos Foram dissecados 30 membros de 15 cadáveres, todos do sexo masculino, preparados por injeção intra-arterial de uma solução de glicerina e formol a 10%. Resultados Em todos os membros dissecados, encontramos pelo menos um ramo destinado a cada uma das cabeças - superficial e profunda - do músculo supinador. Esses tiveram origem no NIP. Identificamos, proximal à arcada de Frohse, umramo para o supinador em seis membros; 2 ramos para o supinador em 11 membros e 3 ramos em 4 membros. Em dois membros, apenas um ramo desprendia-se do NIP, mas se duplicava proximalmente à arcada de Frohse. Em sete membros, não identificamos ramos para o supinador proximal à arcada de Frohse. Os ramos destinados ao músculo supinador foram seccionados na junção neuromuscular, podendo ser conectados sem tensão ao NIP. O diâmetro somado dos ramos destinados ao músculo supinador correspondeu, em média, a 53,5% do diâmetro do NIP. Conclusão Este estudo anatômico mostra que ramos do nervo radial destinados ao músculo supinador podem ser transferidos diretamente para o NIP semtensão para restaurar a extensão do polegar e dos dedos em pacientes com lesões de plexo braquial C7-T1.

ABSTRACT

Abstract: Background: Seborrheic dermatitis is a common disease characterized by the erythematous plaques with oily-yellow desquamation. Increased sebaceous gland activity by androgenic hormones has played a role in the etiology of the disease. The second-to-fourth digit (2D:4D) ratio is thought to be a marker of prenatal androgen exposure. Objectives: To investigate the association between 2D:4D ratios and seborrheic dermatitis in a male population. Methods: Healthy male controls and patients with seborrheic dermatitis were included in this study. One hundred seborrheic dermatitis patients and 120 healthy controls, aged 17-59, were enrolled. A digital Vernier caliper was used to measure the finger lengths. Seborrheic dermatitis severity was assessed using the Seborrheic Dermatitis Area and Severity Index (SDASI). Results: The 2D:4D ratios of the patients (x = 0.977) were significantly lower than those of the controls (x = 1.050) for right hands (t = 6.948; p = 0.000; > 0.05). No similar relationship was found between the 2D:4D ratio for left hands (t = 0.901; p = 0.368; > 0.05). Seborrheic dermatitis severity was negatively correlated with 2D:4D ratios of right hands (r = -0.391; p = 0.000-0.05). Study limitations: One of the main limitations of this study was the small sample, which got a head of us from acquiring certain findings about the 2D:4D ratio and seborrheic dermatitis. The other limitation is that the patient selection did not reflect the general population, as a single clinic was studied. Conclusion: To the authors' knowledge, this is the first study examining the relationship between 2D:4D ratios and seborrheic dermatitis. The result of this study may indicate a line of investigation and can support the theory of prenatal androgen exposure.

ABSTRACT

Abstract Objective To analyze the anatomical variations of the innervation of the flexor digitorum superficialis muscle and to determine if the branch of the median nerve that supply this muscle is connected to the branches to the extensor carpi radialis brevis and the pronator teres muscles, without tension, and how close to the target-muscles the transfer can be performed. Methods Fifty limbs of 25 cadavers were dissected to collect data on the anatomical variations of the branches to the flexor digitorum superficialis muscle. Results This muscle received innervation from the median nerve in the 50 limbs. In 22 it received one branch, and in 28 more than one. The proximal branch was identified in 22 limbs, and in 12 limbs it shared branches with other muscles. The distal branch was present in all, and originated from the median nerve as an isolated branch, or a common trunk with the anterior interosseous nerve in 3 limbs, and from a common trunk with the flexor carpi radialis muscle and anterior interosseous nerve in another. It originated distally to the anterior interosseous nerve at 38, in 5 on the same level, and in 3 proximal to the anterior interosseous nerve. In four limbs, innervation came from the anterior interosseous nerve, as well as from the median nerve. Accessory branches of the median nerve for the distal portion of the flexor digitorum superficialis muscle were present in eight limbs. Conclusion In 28 limbs with two or more branches, one of them could be connected to the branches to the extensor carpi radialis brevis and pronator teres muscles without tension, even during the pronation and supination movements of the forearm and flexion-extension of the elbow.


RESUMO Objetivo Analisar as variações anatômicas da inervação do músculo flexor superficial dos dedos e determinar se o ramo do nervo mediano destinado a esse músculo pode ou não ser conectado aos ramos para os músculos extensor radial curto do carpo e pronador redondo sem tensão, e quão próximo dos músculos-alvo a transferência pode ser realizada. Métodos Foram dissecados 50 membros de 25 cadáveres para coletar dados sobre as variações anatômicas dos ramos para o músculo flexor superficial dos dedos. Resultados O referido músculo recebeu inervação do nervo mediano nos 50 membros. Em 22 recebeu um ramo, em 28 mais que um. O ramo proximal foi identificado em 22 membros e em 12 compartilhava ramos com outros músculos. O ramo distal estava presente em todos e desprendeu-se do nervo mediano como um ramo isolado ou de um tronco comum com o nervo interósseo anterior em 3 membros, e de um tronco comum com músculo flexor radial do carpo e nervo interósseo anterior em outro. Originou-se distalmente ao nervo interósseo anterior em 38, em 5 no mesmo nível e em 3 proximal ao nervo interósseo anterior. Em quatro recebeu inervação do nervo interósseo anterior, além daquela recebida pelo mediano. Ramos acessórios do nervo mediano para a porção distal do músculo flexor superficial dos dedos estavam presentes em oito membros. Conclusão Nos 28 membros em que existam 2 ou mais ramos, 1 desses poderia ser conectado aos ramos para o músculo extensor radial curto do carpo e pronador redondo sem tensão, mesmo durante os movimentos de pronossupinação do antebraço e flexão-extensão do cotovelo.

ABSTRACT

Fibroma of the tendon sheath (FTS) was initially described in 1936 by Geschickter and Copeland as a benign firmed soft tissue tumor that is rare and less common than another soft tissue tumors, especially giant cell tumors (GCT) of the tendon sheath. The common distinct feature is a slow-growing least painful rare entity arising from the tendon or tendon sheath. FTS is detected mostly in the fingers, hands and wrists but less commonly in the foot. Very few cases of FTS have been described arising from a flexor tendon of the foot. This article describes a 51-year-old patient with FTS that developed in the extensor tendon of the foot, which is the only known FTS to form in this area. Heterogeneous low signal intensity in both the T1- and T2-weighted images was observed in magnetic resonance imaging. The lesion was excised completely by open surgery. Histologically, it showed randomly arranged, fibroblast-like spindle cells in dense fibrous tissue and had insufficient hemosiderin-laden macrophages that are typical for GCT.

ABSTRACT

STUDY DESIGN: Retrospective study. PURPOSE: We experienced the situation wherein some patients had new-onset pain or dysesthesia around the ring and little fingers (C8 symptom) or ulnar aspect of the forearm (T1 symptom) after cervical laminoplasty (LP). We investigated the incidence and the cause of new C8 or T1 symptoms and the clinical outcomes after C3–C6 LP or C3–C7 LP. OVERVIEW OF LITERATURE: There were some reports regarding complications after cervical LP. However, there was no report regarding C8 or T1 symptoms after cervical LP. METHODS: Among the 33 patients enrolled in this study, 11 and 22 patients were treated with C3–C6 LP and C3–C7 LP, respectively. We prospectively evaluated C8 or T1 symptoms daily postoperatively for 1 week. The distance of the posterior spinal cord shifting and posterior subarachnoid space from C2 to T1 was measured by T2-weighted midsagittal magnetic resonance imaging (MRI). We evaluated pre- and postoperative axial neck pain, Japanese Orthopaedic Association (JOA) score, and JOA score improvement rate. RESULTS: C8 or T1 symptoms occurred in five and three patients with C3–C6 LP (45.5%) and C3–C7 LP (13.6%), respectively. The distance of the posterior subarachnoid space in C3–C6 LP at C7 was significantly shorter than that in C3–C7 LP at T1 on MRI 24 hours postoperatively (p=0.0448). Postoperative axial neck pain, pre- and postoperative JOA scores, and JOA score improvement rate were not significantly different. CONCLUSIONS: The incidence of C8 or T1 symptoms in C3–C6 LP was higher than that in C3–C7 LP. C8 or T1 symptoms would be caused by the posterior fila radicularia and spinal cord impingement on the intact lower end of the lamina.

ABSTRACT

PURPOSE: To investigate the correlation between the tenosynovitis pattern on two-phase bone scintigraphy (2P-BS) and clinical manifestation in patients with suspected rheumatoid arthritis (RA).METHOD: 2P-BS including technetium-99m-methylene diphosphonate blood pool and bone phase imaging in 402 consecutive patients with clinically suspected RAwere retrospectively reviewed. According to 2010 RA Classification Criteria, patients were grouped as RA and non-RA. Visual assessment of all fingers, toes, wrists, and ankles on 2P-BS was performed. Clinical suspected tenosynovitis was evaluated on physical examination. Rheumatoid factor, anti-cyclic citrullinated protein antibody, C-reactive protein, and estimated sedimentation rate were obtained. Radiographic findings were also used to define early and established arthritis.RESULTS: Tenosynovitis pattern was detected in 12.7%(51/402 patients) on 2P-BS.A total of 94.1%(48/51) were diagnosed as RA vs. 5.9% (3/51) as non-RA. Of the 48 RA patients with positive 2P-BS finding, 85.4% (41/48) had early arthritis and 14.6% (7/48) had established arthritis. On physical examination, tenosynovitis was suspected in 21.9% (88/402). A total of 56.8% (50/88) belonged to the RA group and 43.2% (38/88) to the non-RA group. The tenosynovitis pattern of 2P-BS and physical examination showed statistical difference and moderate agreement. The positive tenosynovitis pattern on 2P-BS represented up to 26.408 of odds ratio which was highest among the RA-associated factors.CONCLUSION: Tenosynovitis pattern on 2P-BS was more commonly detected in the RA group and was more frequently associated with early arthritis pattern. Therefore, 2P-BS could give additional information for the detection of subclinical tenosynovitis in early or preclinical RA patients.
