AIM: Patients with an ultra-short uterine cervix as a result of large conization, repeated conization or radical trachelectomy (RT), are at high risk of preterm premature rupture of the membrane, which leads to preterm birth. We have commenced performing transabdominal cerclage (TAC) of the uterine cervix for these patients. In this study, we examined the safety of TAC and its impact on pregnancy. METHODS: We have performed TAC in 11 patients before pregnancy: in six after large cervical operations, such as repeated conization; and in five for difficulties with cervical cerclage after RT...

BACKGROUND: Manual thrombus aspiration during primary percutaneous intervention provides us with aspirated thrombus sample, that may contain material from the disrupted plaque. Immunohistopathological analysis of thrombus can yield valuable information about the clinical and cardiovascular outcomes and possible mechanisms of myocardial infarction. MATERIAL AND METHODS: We studied and analysed the immunohistopathological features of coronary thrombus aspirated from patients undergoing primary percutaneous coronary angioplasty...

BACKGROUND: The C5-C6 nerve roots are usually spared from avulsion after brachial plexus injury (BPI) and thus can be used as donors for nerve grafting. To date, there are no appropriate animal models to evaluate spared nerve root stumps. Hence, the aim of this study was to establish and evaluate a rat model with spared nerve root stumps in BPI. NEW METHOD: In rupture group, the proximal parts of C5-T1 nerve roots were held with the surrounding muscles and the distal parts were pulled by a sudden force after the brachial plexus was fully exposed, and the results were compared with those of sham group...

OBJECT: The wall thickness of intracranial aneurysms (IAs) is heterogeneous. Although thinning of the IA wall is thought to contribute to IA rupture, the underlying mechanism remains poorly understood. Recently, imaging mass spectroscopy (IMS) has been used to reveal the distribution of phospholipids in vascular diseases. To investigate the feature of phospholipid composition of IA walls, we conducted IMS in a rat model of experimentally induced IA. MATERIAL AND METHODS: IAs were surgically induced in 7-week-old male rats and analyzed by IMS in negative-ion mode...

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare peripheral T cell lymphoma. BIA-ALCL is a disease of the fibrous capsule surrounding the implant and occurs in patients after both breast reconstruction and augmentation. More than 300 cases have been reported so far, including two in a transgender patient. Here we describe BIA-ALCL presented with a mass in a transgender patient and the first case of BIA-ALCL in the Czech Republic. In 2007, a 33-year-old transgender male to female underwent bilateral breast augmentation as a part of his transformation to female...

The Anterior Tibialis is the most important muscle in ankle dorsiflexion. The anterior tibialis tendon (ATT)'s rupture is an infrequent condition which can be both traumatic and spontaneous. Clinic is poor and it is necessary to confirm the suspect by US or MRI. The reported case refers to a 40 years old man who had a direct trauma at ankle and midfoot which was originally conservatively treated for an ankle sprain. Three months later he returned with pain, swelling and paresthesia. MRI was performed showing a neoformation in the contest of ATT's rupture...

Papillary muscle (PM) rupture is a rare complication of acute myocardial infarction which carries an excessive mortality rate. Optimal outcomes require rapid diagnosis and prompt surgical referral, and in this regard, echocardiography plays a crucial role. Comprehensive echocardiographic examination of the patient with PM rupture consists of identification of the ruptured PM segment, visualization of flail mitral valve segment(s), evaluation of mitral regurgitation severity, and assessment of left ventricular systolic function...

AIM: An increased density of intraplaque (IP) microvessels in ruptured versus nonruptured human plaques suggests that IP neovascularization has a major causative effect on plaque development and instability. Possibly, vascular endothelial growth factor (VEGF) or other angiogenic factors mediate IP microvessel growth and plaque destabilization. Because apolipoprotein deficient mice with a heterozygous mutation (C1039G+/-) in the fibrillin-1 gene (ApoE(-/-)Fbn1(C1039G+/-)) manifest substantial IP neovascularization, they represent a unique tool to further investigate angiogenesis and its role in atherosclerosis...

REVIEW
Kamran S Hamid, Annunziato Amendola
Chronic rupture of the peroneal tendons can be a functionally limiting condition with a multitude of causes. Conservative and operative interventions are heterogenous and tailored to the functional demands of the patient. Surgical plans are based on muscle viability, patient preference, and surgeon expertise. Clinical outcomes evidence remains limited in this domain, and further well-designed studies are warranted to guide treatment.

REVIEW
Christopher E Gross, James A Nunley
Although most astute clinicians can diagnose Achilles tendon ruptures by physical examination alone, more than 20% are not accurately diagnosed in a timely fashion. The definition of a "chronic" Achilles tendon rupture in foot and ankle literature varies widely: from 4 to 10 weeks status after injury. Neglected or chronic Achilles tendon ruptures can be significantly disabling to patients if the muscle-tendon unit is stretched beyond its normal passive limit. There are a variety of treatment options that all have valid uses but have not been proven to be superior to one another...

Chronic Achilles tendon ruptures are debilitating injuries and are often associated with large tendon gaps that can be challenging for the foot and ankle surgeon to treat. Preoperative evaluation should include the patient's functional goals, medical comorbidities, MRI assessment of gastrocsoleus muscle viability, condition of adjacent flexor tendons, and size of the tendon defect. Although several surgical techniques have been described, the surgeon must formulate an individualized treatment plan for the patient...

Dong-Il Chun, Jun-Hyuck Lee, Jaeho Cho
Closed rupture of the extensor hallucis longus (EHL) tendon is rare, with most cases caused by either direct penetrating trauma or predisposing factors such as corticosteroid injection and iatrogenic trauma incidences. Almost all of the previous case reports have reported on rupture of the EHL tendon rather than the EHL muscle. In this report, we highlight an unusual clinical presentation of a rupture of the EHL muscle and discuss its predisposing factors. This patient was a taekwondo athlete with EHL muscle rupture secondary to repetitive overuse without any underlying systemic or local predisposing factors or direct trauma...

INTRODUCTION: Several factors, such as aging, pregnancy, and weight loss, reduce the elasticity of the breast tissue, and ptosis occurs. Due to aging and gravity, it is not possible to completely prevent breast ptosis. The goal is to delay the recurrence of ptosis as much as possible. PATIENTS AND METHODS: This study included 20 female patients aged 25-55 years. The patients who underwent surgery had different levels of ptosis. Although the patients wanted their breasts to be lifted and an increase in projection, they did not want implants to be used...

Comparative analyses of transcriptional profiles from humans and mice with cardiovascular pathologies revealed consistently elevated expression of MICU2, a regulatory subunit of the mitochondrial calcium uniporter complex. To determine if MICU2 expression was cardioprotective, we produced and characterized Micu2(-/-) mice. Mutant mice had left atrial enlargement and Micu2(-/-) cardiomyocytes had delayed sarcomere relaxation and cytosolic calcium reuptake kinetics, indicating diastolic dysfunction. RNA sequencing (RNA-seq) of Micu2(-/-) ventricular tissues revealed markedly reduced transcripts encoding the apelin receptor (Micu2(-/-) vs...

BACKGROUND: Optimizing calf muscle performance seems to play an important role in minimizing impairments and symptoms after an Achilles tendon rupture (ATR). The literature lacks long-term follow-up studies after ATR that describe calf muscle performance over time. PURPOSE: The primary aim was to evaluate calf muscle performance and patient-reported outcomes at a mean of 7 years after ATR in patients included in a prospective, randomized controlled trial. A secondary aim was to evaluate whether improvement in calf muscle performance continued after the 2-year follow-up...

In East Asia, a square face is considered unattractive, and mandibular contouring surgery is commonly used to give a smooth contour to the lower jaw. Mandibular contouring surgery occasionally involves not only osteotomy of the mandibular angle but also resection of the masseter muscle via an intraoral approach. This type of mandibular contouring surgery poses a risk of injury to the premasseteric branch of the facial artery and massive haemorrhage. Here we report a patient who presented to our hospital with severe haemorrhage, swelling and airway constriction after bilateral mandibular angle and plane osteotomy with resection of the masseter muscle performed elsewhere as an office-based day surgery...

BACKGROUND: Extensor mechanism rupture (EMR) of the knee is a rare but potentially debilitating injury that often occurs due to trauma. While a wide variety of surgical treatments have been reported, there is currently no consensus on the most successful treatment method. The timing of post-operative joint mobilization is also critical for successful recovery after EMR repair. Despite the traditional method of complete immobilization for 6 weeks, there is an increasing trend towards early post-operative knee mobilization...
