There have been few reports about ratchet syndrome. We report a case of ratchet syndrome caused by small hair-pin curve of lead that triggered the lead retract itself. A 69-year-old man with a past history of inferior wall myocardial infarction, presented with progressive congestive heart failure. He underwent implantation of cardiac resynchronization therapy with an implantable cardiac defibrillator (CRTD) at our hospital. At 33 days after implantation, shock lead dislodgement was revealed. X-ray showed that the lead tip was in left subclavian vein, leaving its screw out, and a large part of the proximal portion of the lead was retracted into the pocket, while the other two leads remained in appropriate positions and the device had not rotated...

Eustachian tube dysfunction is believed to be an important factor to cholesteatoma development and recurrence of disease after surgical treatment. Although many studies have described prognostic factors, evaluation methods, or surgical techniques for Eustachian tube dysfunction, they relied on the soft tissues of its structure; little is known about its bony structure-the protympanum-which connects the Eustachian tube to the tympanic cavity, and can also be affected by several inflammatory conditions, both from the middle ear or from the nasopharynx...

Twiddler's syndrome is caused by patient manipulation of the cardiac implantable device (CID) around its central axis within the pocket resulting in retraction and dislocation of the electrodes. There are however some reports that Twiddler's syndrome may occur spontaneously without the patient`s manipulation (ref). This remains contentious as it may be argued that patients may not want to admit to manipulating the CID or may have been unaware of their actions. Recently, we have observed three very similar cases with a "spontaneous" Twiddler's syndrome resulting in lead displacement...

INTRODUCTION: The occurrence of empyema after pneumonectomy or in suites with chronic pleural pocket is a dreaded complication. The management is long and difficult. The authors report their experience before this complication including infection control by an emptying of the pleural pocket percutaneous drainage or thoracostomy which will be complemented by a thoracomyoplasty the aim to erase the pleural pocket. MATERIALS AND METHODS: This is a retrospective study conducted between 2009 and 2015 concerning the records of 9 patients treated for empyema or in the aftermath of a lung resection or as part of a chronic pleural pocket and calcific...

In order to provide a basis for meaningful exchange of information among those treating cholesteatoma, the Committee on Nomenclature of the Japan Otological Society (JOS) was appointed in 2004 to create a cholesteatoma staging system as simple as possible to use in clinical practice in Japan. Following the announcement of preliminary criteria for the staging of pars flaccida (attic) cholesteatoma in 2008, we proposed the 2010 JOS staging system for two major types of retraction pocket cholesteatoma, pars flaccida and pars tensa cholesteatoma...

We conducted a prospective, observational study over a 3-year period to compare the clinical, functional, and surgical findings in children with chronic bilateral otitis media with effusion who underwent one of three different types of treatment. Our study population was made up of 150 patients-79 boys and 71 girls aged 24 to 84 months-who were randomly assigned to one of the three treatment groups of 50 patients each. One group was treated with myringotomy, tympanostomy tube insertion, and adenoidectomy (T+A group); another with a combination of physical conservative treatment and adenoidectomy (P+A group); and the third with physical conservative treatment alone (P-only group)...

Sertoli cells (SCs) play a central role in the development of germ cells within functional testes and exhibit varying morphology during spermatogenesis. This present study investigated the seasonal morphological changes in SCs in the reproductive cycle of Pelodiscus sinensis by light microscopy, transmission electron microscopy (TEM), and immunohistochemistry. During hibernation period with the quiescent of spermatogenesis, several autophagosomes were observed inside the SCs, the processes of which retracted...

The twiddler syndrome results in retraction and coiling of the lead in the pacemaker pocket with subsequent pacemaker malfunction. If the lead׳s parameters are not affected, then the problem can be corrected by lead repositioning. We describe the first reported case of a dramatic pacemaker lead coiling with a double level of lead compromise, with one of them being intra-cardiac. This condition affected our treatment strategy, as the repositioning of the lead was unfeasible.

INTRODUCTION: Same-day closure of bilateral tympanic membrane perforations is a quick and more comfortable procedure for the patients. However, conventional bilateral same-day tympanoplasty or myringoplasty has been rarely performed because of the theoretical risk of postoperative complications. OBJECTIVE: To evaluate the advantages and outcomes of bilateral simultaneous endoscopic cartilage tympanoplasty in patients with bilateral tympanic membrane perforations...

BACKGROUND AND AIM: Cholesteatoma usually arises in the middle ear by the formation of a retraction pocket or a tympanic membrane perforation. In some cases, cholesteatoma presents behind an intact tympanic membrane (ITMC) and the underlying mechanism of its development is controversial. The aim of this study was to describe clinical features, pathogenesis and surgical results in a series of adult patients affected by ITMC. METHODS: We analyzed retrospectively 27 adult patients (age > 18 years) diagnosed with ITMC who underwent surgery between 1994 and 2013...

OBJECTIVES/HYPOTHESIS: To compare the volume of the epitympanic space, as well as the area of the tympanic isthmus, in human temporal bones with retraction pockets to those with chronic otitis media without retraction pockets and to those with neither condition. STUDY DESIGN: Comparative human temporal bone study. METHODS: We generated a three-dimensional model of the bony epitympanum and measured the epitympanic space. We also compared the area of the tympanic isthmus...

OBJECTIVES/HYPOTHESIS: Chronic suppurative otitis media (CSOM) is a common infectious condition that can cause hearing loss and persistent otorrhea. The prevalence rates of CSOM in developed countries is typically <1%, whereas developing countries and some racial groups have shown higher prevalence rates exceeding 4%. The aim of this study was to investigate the prevalence of CSOM in South Korea and associated factors using data from the Korea National Health and Nutrition Examination Survey during 2009-2012...

The eardrum separates the external ear from the middle ear and it is responsible to convert the acoustical energy into mechanical energy. It is divided by pars tensa and pars flaccida. The aim of this work is to analyze the susceptibility of the four quadrants of the pars tensa under negative pressure, to different lamina propria fibers distribution. The development of associated ear pathology, in particular the formation of retraction pockets, is also evaluated. To analyze these effects, a computational biomechanical model of the tympano-ossicular chain was constructed using computerized tomography images and based on the finite element method...

BACKGROUND: The aim of unilateral breast reconstruction after mastectomy is to craft a natural-looking breast with symmetry. The latissimus dorsi (LD) flap with implant is an established technique for this purpose. However, it is challenging to obtain adequate volume and satisfactory aesthetic results using a one-stage operation when considering factors such as muscle atrophy, wound dehiscence and excessive scarring. The two-stage reconstruction addresses these difficulties by using a tissue expander to gradually enlarge the skin pocket which eventually holds an appropriately sized implant...

BACKGROUND: The pacemaker-twiddler's syndrome is an uncommon cause of pacemaker malfunction. It occurs due to unintentional or deliberate manipulation of the pacemaker pulse generator within its skin pocket by the patient. This causes coiling of the lead and its dislodgement, resulting in failure of ventricular pacing. More commonly reported among elderly females with impaired cognition, the phenomenon usually occurs in the first year following pacemaker implantation. Treatment involves repositioning of the dislodged leads and suture fixation of the lead and pulse generator within its pocket...
