Accessory ossicles are the skeletal variations of the ankle and foot that can cause painful syndromes. The accessory navicular
bone is one of the most common accessory ossicle of the foot (4–21%) and is also known as os tibiale, os tibiale externum
and os naviculare secundarium. This bone can be adjacent to the posteromedial tuberosity of the navicular bone or can be separated
and may cause various diseases in the foot and mimic fractures of foot bones. The aim of this study was to document a detailed
investigation of incidence and types of accessory navicular bones of Turkish subjects according to sex in both extremities.
The accessory navicular bone was detected (11%) via the posterior–anterior radiographs of 650 subjects in the radiological
examination. The incidences of accessory navicular bones were identified as 6.1–4.9% in female and male participants. Accessory
navicular bones were classified into three groups as Type I, Type II and Type III and the incidences of these bones were determined
as 3.3, 3.1, 4.6%, respectively. Each group was also divided into subgroups. The incidences of the subgroups are as Type Ia
0.6%, Type Ib 1.5%, Type Ic 1.2%, Type IIA/a 0.8%, Type IIA/b 0.4%, Type IIA/c 0%, Type IIB/a 1.1%, IIB/b 0.3%, IIB/c 0.5%,
Type IIIa 1.5%, Type IIIb 1.4%, Type IIIc 1.7%. Finally, the types of accessory navicular bones were discussed and the imaging
modalities for diagnosis were presented. 相似文献

BACKGROUND: Depression is prevalent among university students. It is debilitating and affects the academic performance of students. One of the most common reasons why students consult counselling centres is depression. Therefore it is important to assess the university students' depression by valid measures designed particularly for this purpose. METHOD: The present study developed the "University Student Depression Inventory" (USDI) to measure the depressive symptoms of university students. RESULT: Items based on a broad range of depression symptoms were subjected to factor analysis, resulting in a 30 item scale with three subscales: Lethargy; Cognitive/Emotional; and Academic Motivation. Psychometric investigation revealed satisfactory reliability and divergent and convergent validity. CONCLUSION: It is expected that multidimensional USDI would be a useful tool for university counselling services to assess the depression of the students. 相似文献

Carpal tunnel decompression is one of the most common surgical procedures in hand surgery. Cutaneous innervation of the palm
by median and ulnar nerves was evaluated to find a suitable incision preserving cutaneous nerves. A morphometric study was
designed to define the safe-zone for mini-open carpal tunnel release. Sixteen fresh-frozen (8 right, 8 left) and 14 formalin-fixed
(8 right, 6 left) cadaveric hands were dissected. Anatomy of the palmar cutaneous branch of the median and the ulnar nerve,
motor branch of the median nerve, superficial palmar arch were evaluated relative to the surgical incision. We also identified
the motor branch of the median nerve. Detailed measurements of the whole palmar region are reported in this study. The motor
branch of the median nerve was extraligamentous as 60%, subligamentous as 34%, transligamentous as 6%. The palmar cutaneous
branches of the median and the ulnar nerves in the palmar region were classified as Type A (34%), Type B (13%), Type C (13%),
Type D (none), Type E (40%) according to forms of palmar cutaneous innervation originating from the ulnar and median nerves.
Injury to the palmar cutaneous branch of the median nerve (PCBMN) is the most common complication of the carpal tunnel surgery.
Various techniques were described to decrease post-operative morbidity. Based on these anatomic findings mini incision between
the superficial palmar arch and the most distal part of the PCBMN in the palmar region is the safe-zone for carpal tunnel
surgery. 相似文献

Behcet's disease (BD) has been known for many years, yet the etiology of the systemic vasculitis remains unknown. Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide (NO) synthase. ADMA is involved in endothelial dysfunction in various vascular diseases and its level in BD is unclear. This study was performed to evaluate the relationship between ADMA and NO levels in plasma of patients with BD. There were 3 groups of 30 subjects: (a) controls, (b) BD patients with mucocutaneous involvement, and (c) BD patients with vascular involvement. Plasma NO levels were assayed by spectrophotometry and plasma ADMA levels were assayed by an ELISA test. Plasma ADMA levels were higher in both groups of BD patients than in the controls; the ADMA levels were higher in the BD patients with vascular involvement than in the mucocutaneous group. Plasma NO levels were lower in both groups of BD patients than in controls; plasma NO levels were lower in the BD patients with vascular involvement than in mucocutaneous group. In the combined groups of 60 BD patients, there was significant inverse correlation between the plasma concentrations of ADMA and NO (r = -0.570, p <0.001). Plasma lipid profiles did not differ significantly between the BD patients and the controls. These results are evidence for increased plasma ADMA levels and decreased plasma NO levels as risk factors for cardiovascular events in BD patients. Inhibition of NO synthesis by ADMA may contribute to vascular involvement in BD. 相似文献

Objective
A high dose of prolonged gonadotropins can yield higher numbers of oocytes and embryos. The high dose or prolonged regimens can be associated with ovarian hyperstimulation syndrome (OHSS), multiple gestations, emotional stress, economical burden and treatment dropout. In mild stimulation lower doses and shorter duration times of gonadotropin are used in contrast to the conventional long stimulation protocol in IVF. It has been proposed that supraphysiologic levels of hormones may adversely affect endometrium and oocyte/embryo. Also it has been proposed that oxidative stress (OS) may alter ovarian hormone dynamics and could be further affected by additional exogenous hormonal stimulation. Therefore our aim was to compare follicular fluid total antioxidant capacity (TAC) in antagonist mild and long agonist stimulations.Materials and Methods
Forty patients received antagonist mild stimulation, starting on the 5th day of their cycle and forty patients received long agonist treatment. Seventy-five patients undergoing their first IVF cycle were included in the final analysis. Follicular fluid (FF) samples were analyzed for estradiol (E2), antimullerian hormone (AMH) and TAC.Results
FF-Total antioxidant capacity (TAC) levels were higher in the long agonist group as opposed to the antagonist group [1.07 ± 0.04 mmol Trolox equivalent/L vs 1 ± 0.13 mmol Trolox equivalent/L] (Fig. 1). Pregnancy rates were not significantly different between the two treatments. The FF-TAC levels were not different among infertility etiologies (Fig. 3). FF-TAC levels did not have a direct correlation with pregnancy but a positive correlation with the total gonadotropin dose was observed.Conclusion
Patients with good ovarian reserves and under the age of 35 effectively responded to mild stimulation treatment. Using lower amounts of gonadotropin, yielded less FF-TAC levels in patients who underwent antagonist mild protocol. In patients under the age of 35, antagonist mild stimulation is a patient friendly and effective procedure when undergoing their first IVF cycle. 相似文献106.

PURPOSE: The purpose of this study was to describe the computed tomography (CT) and magnetic resonance (MR) imaging findings of hibernoma. MATERIALS AND METHODS: We retrospectively evaluated imaging findings of CT and MR examinations of six patients (three men and three woman, aged 27-48 years) with histopathological diagnosis of hibernoma. RESULTS: On CT examination, the lesions were slightly hyperdense, and on T1- and T2-weighted MR images, they were isointense or slightly hypointense compared to the subcutaneous fat. All of these lesions showed contrast enhancement and one out of the six lesions had internal linear septations. CONCLUSION: Hibernoma has a wide spectrum of CT and MR imaging findings, which should be considered in differential diagnosis, especially with other lipomatous lesions. 相似文献

Basement membranes (BMs) in 201 soft tissue tumours were quantified using computerized image analysis of tissues immunostained for laminin and type IV collagen. The purpose of the study was to compare and quantify the extent of BM deposition in a large and varied group of benign and malignant tumours. Laminin and type IV collagen gave similar results. The difference between benign and malignant was statistically highly significant (P=0·0001), with greater deposition in benign tumours. BM deposition was homogeneous in benign tumours and heterogeneous in sarcomas and appeared to correlate with the degree of differentiation. Some poorly differentiated sarcomas showed cytoplasmic laminin staining but little or no extracellular BM. Immunohistochemical evaluation of BM has some advantages over electron microscopy; specialized equipment is not needed and since large samples can be studied with little sampling error, heterogeneity can be studied more readily. Subjective visual assessment gives a good overall indication of the extent of BM deposition and in many situations is likely to be a suitable alternative to image analysis. Because of staining heterogeneity, BM immunohistochemistry is unlikely to be of significant value in the diagnosis of specific types of sarcoma. © 1998 John Wiley & Sons, Ltd. 相似文献
