All the results refer to optical microscopy and universal-stage analyses performed on petrographic thin sections. Our results show that such shock-related microstructures do have a preferred orientation, but also that relating their orientation with the possible shock wave propagation is quite challenging and potentially impossible. This is largely due to the lack of dedicated experiments to provide a key to interpret the observed preferred orientation and to the lack of information on postimpact orientation modifications, especially in the case of the drill core samples.

Efforts in the prevention and treatment of depression among Hispanic immigrant women require studies to identify modifiable factors of depression. Some factors that may merit investigation are gender roles such as egalitarian gender attitudes, marianismo, and self-silencing.

This cross-sectional study included 231 Hispanic immigrant women living in Miami-Dade County, Florida. Logistic regression was used to examine associations of covariates, egalitarian gender attitudes, marianismo, and self-silencing in relation to depression.

Egalitarian gender attitudes were not associated with depression. For marianismo domains, higher scores on the spiritual pillar scale were associated with lower odds of depression. With regard to self-silencing, higher scores on externalizing self-perception and divided self were associated with higher odds of depression.

Findings add to the limited literature on depression among Hispanic immigrants and provides some insight on sociocultural factors that may be considered in depression interventions for Hispanic immigrant women.

In both our results, we permit the amount of color made available to vertices of lower degree to be accordingly lower. One result concerns list coloring and correspondence coloring, while the other concerns fractional coloring. Our proof of the second illustrates the use of the hard-core model to prove a Johansson-type result, which may be of independent interest.

The soft tissue envelope around the knee can have an impact on the ease of performing surgery such as total knee replacement (TKR). BMI is often used in planning theatre time but may be a poor indicator of the soft tissue around the knee due to varying distribution of adipose tissue. Radiological images directly show the soft tissue. We therefore aim to develop a method of quantifying the soft tissue envelope around the knee using radiographs.

Plain weight-bearing radiographs were used to measure the total knee (soft tissue and bony) width at the level of the epicondyles of the knee and the bony epicondylar width of the femur. The ratio of the two widths was defined as the Soft Tissue Radiological Knee (SToRK) Index. The validity of the index as a true measure of soft tissue envelope was assessed using cross sectional areas on axial MRI cuts at the level of the epicondyles. The inter-observer reliability was assessed using the intra-class correlation coefficient. SToRK Index values were correlated with patients’ BMI, gender and operative time.

The results show there is a close correlation between the ratio of cross sectional area of MRI axial cuts at the level of epicondyles and the ratio of linear widths measured on plain radiographs, validating the SToRK Index as a measure of soft tissue envelope. There was also good to excellent inter-rater reliability of measurements of these widths. There was a close correlation between BMI and SToRK Index with differences between men and women.

We believe the SToRK Index is a validated method of quantifying soft tissue distribution around the knee and gives surgeons a better descriptor of the knee envelope than BMI. It is easy to use, needs simple investigations and is reproducible.

Medial Compartment Osteoarthritis of the knee is becoming a widespread problem. The surgical options include high tibial osteotomy, unicompartmental knee replacement, and total knee replacement. Replacement surgeries are not advised in the younger age group, so in these patients, high tibial osteotomy is the only option. selleck products In this study, we have assessed the functional and radiological outcomes of high tibial osteotomy done by hemicallostasis method.

We report the outcome of 30 patients (30 knees) who underwent hemicallostasis with a dynamic external fixator for medial compartment osteoarthritis of the knee. The radiological assessment was done with the help of Hip Knee Ankle angle. The functional scoring was done via Oxford knee score, IKDC, KOOS, and WOMAC score.

At a mean follow up of 35 months, the preoperatively mean HKA angle was 172±30. The mean HKA angle postoperatively was 184±10. Appropriate correction of the HKA angle was achieved in 24 of 30 patients (80%). Whereas, there was under correction nt Osteoarthritis of the knee. Hip Knee Ankle Angle is an important parameter to restore for better functional outcomes. The Advantage of using a dynamic axial fixator is the precision in achieving calculated correction without any implant in the bone once the correction is achieved along with good healing rates.The osteochondroma of metatarsal is a rare clinical entity. It generally occurs in the first or second decade of life. The osteochondroma should be investigated to rule out any malignant changes before embarking any surgical intervention. We report an osteochondroma of 5th metatarsal in a 65 years old female as an unusual aetiology of foot pain. We propose the scalloping effect of the osteochondroma on adjacent metatarsal as one of the mechanisms of causing pain in the foot. After ruling out the malignant transformation with the help of MRI, excision of the tumour was done with a curvilinear incision on the dorsum of the foot. There was no recurrence in 1 year follow up. This case report depicts the occurrence of osteochondroma in geriatric patient as an unusual cause of foot pain. The scalloping effect on the adjacent bone and tissues can be the aetiology of the pain.
