[Total hip arthroplasty with supracondylar shortening osteotomy in Crowe 4 inveterate hip dislocation: case report and surgical technique].

Structural deformities of the acetabulum secondary to developmental dysplasia of the hip (DDH) are one of the most common causes requiring total hip arthroplasty (THA), whether in conjunction with femoral osteotomy in cases of Crowe dislocation 4. Several techniques have been described, studied, and compared, but there is no superiority of one technique over another. Currently, most hip surgeons perform a subtrochanteric osteotomy.

[Radiographic measurements of acetabular component orientation with Widmer´s method in total hip arthroplasty. Descriptive case series].

Introduction: total hip arthroplasty (THA) is one of the most performed surgeries worldwide, with high satisfaction rates. The orientation of the acetabular component has a direct impact on the risk of dislocation, recently with the support of robotic surgery the margin of error in implant placement has decreased; however, the conventional technique even without fluoroscopic support continues to have satisfactory results within the safety zone.

Material And Methods: retrospective, cross-sectional, descriptive case series of patients treated with THA at Hospital General Xoco between 2022 and 2024.

Gender effect of glucose, insulin/glucagon ratio, lipids, and nitrogen-metabolites on serum HGF and EGF levels in patients with diabetes type 2.

Hepatocyte growth factor (HGF) exhibits potent growth-inducing properties across various tissues, while epidermal growth factor (EGF) acts as a molecular integration point for diverse stimuli. HGF plays a crucial role in hepatic metabolism, tissue repair, and offers protective effects on epithelial and non-epithelial organs, in addition to its involvement in reducing apoptosis and inflammation, underscoring its anti-inflammatory capabilities. The HGF-Met system is instrumental in hepatic metabolism and enhancing insulin sensitivity in animal diabetes models.

[Parosteal osteosarcoma of the femur and salvage surgery with intercalary prosthesis. Experience in a third level unit and surgical technique].

Introduction: parosteal osteosarcoma is an extramedullary malignant bone tumor in which cells produce osteoid, represents less than 5% of all osteosarcomas, it occurs predominantly in women between the second and fourth decade of life. It is often located in the distal region of the femur and proximal tibia. Clinically it presents with increased volume and thigh or knee pain.

Epicardial adipose tissue thickness is related to early subclinical myocardial dysfunction, particularly in patients with type 2 diabetes mellitus: a case control study.

Background: Cardiac myofibrillary dysfunction, which can be measure by echocardiographical strain value, represents an early subclinical manifestation of heart failure. Epicardial Adipose tissue (EAT) is related to low degree inflammation and oxidative damage in the adjacent tissue.

Intraoperative complexity and risk factors associated with conversion to open surgery during laparoscopic cholecystectomy in eight hospitals in Mexico City.

Background: The conversion to open surgery (COS) during the Laparoscopic Cholecystectomy (LC) is reported to occur at a rate of 10-15%. Some preoperative risk factors (RF) have been postulated; however, few studies have evaluated these factors and the intraoperative complexity with the COS rate. The aim of the study was to evaluate the preoperative RF and intraoperative complexity using the Parkland grading scale (PGS) with the COS rate in LC.

Atypical femoral fracture, case report and literature review.

Introduction: Bisphosphonates have been the gold standard in the management of osteoporosis. Its antiresorptive effect has reduced the incidence of fractures due to bone fragility, as well as its impact on public health. We present the clinical case of a patient in prolonged treatment with bisphosphonates and atypical bilateral femur fracture.

The role of oxidant stress and gender in the erythrocyte arginine metabolism and ammonia management in patients with type 2 diabetes.

Objectives: To study the differences in the levels of nitrogen metabolites, such as ammonia and nitric oxide and the correlations existing among them in both red blood cells (RBCs) and serum, as well as the possible differences by gender in healthy subjects and patients with type 2 Diabetes Mellitus (DM).

Design And Methods: This cross-sectional study included 80 patients diagnosed with type 2 DM (40 female and 40 male patients) and their corresponding controls paired by gender (40 female and 40 male). We separated serum and RBC and determined metabolites mainly through colorimetric and spectrophotometric assays.

[Treatment of an old Achilles tendon rupture with allografts. Report of case series].

Rupture of Achilles tendon occurs at 2-6 cm from its attachment in the calcaneus; its frequency is estimated at 7-18 cases per 100,000 population in the United States and it occurs more frequently in males. The diagnosis is made clinically and with ultrasound or magnetic resonance imaging and treatment may be divided into acute or late. We present herein the use of allograft to treat patients with ruptures more than six weeks old; several techniques were used depending on the rupture site and the available allograft.
