OBJECTIVE

In this article we review the literature on the inferior labial gland from a clinical and anatomical perspective.

BACKGROUND

Regardless of its importance in clinical practice, there are no medical literature that comprehensively reviewed the inferior labial gland.

METHODS

A database search using PubMed and Google Scholar was conducted. The following keywords were used in the search: "lower labial salivary gland", "lower labial gland", "inferior labial salivary gland", AND "inferior labial gland".

CONCLUSIONS

The human labial glands are types of minor salivary gland that continuously secrete small amounts of mucous and serous substances to maintain oral health. The inferior labial glands are innervated by the inferior labial branch of the mental nerve, and the inferior labial branch of the facial artery is the main arterial supply to the lower lip. Although they only have an auxiliary role in saliva production compared to the major salivary glands, minor salivary glands provide a certain amount of lubrication in the oral cavity by the continuous outflow of saliva. The inferior labial gland not only promotes moisturization in the oral cavity but also secretes substances with antibacterial effects, which is important for the function of the oral cavity. A recent study showed that the rate of salivary secretion from the inferior labial glands does not change with age, and in some cases the inferior labial glands are used for diagnosing intractable diseases such as Sjogren's syndrome and cystic fibrosis. In addition, since the inferior labial glands themselves can be the site of cyst and/or neoplasia development, we should be careful to distinguish them from other diseases. Elucidation of the anatomy, physiology, and pathology of the inferior labial glands, is important for understanding human health and diseases.

Meta-Analysis

OBJECTIVE

The primary aim of this article was to establish the actual prevalence of transposition and duplication of the inferior vena cava and to increase awareness about them.

METHODS

A meta-analysis of prevalence was conducted of cases obtained from PubMed, Web of Science, and Scopus databases.

RESULTS

A total of 48 studies contained data that allowed us to estimate the prevalence of these variants (39 for duplication and 32 for transposition). The overall prevalence of duplication was 0.7%, with a 95% confidence interval between 0.5% and 0.9%; for transposition, the prevalence was 0.3%, with a 95% confidence interval between 0.2% and 0.5%. The publication bias was minimal. Duplication prevalence was significantly higher in anatomy studies compared with imaging and surgery studies; for transposition, there were no statistically significant differences by detection technique.

CONCLUSIONS

The overall prevalence of duplication of the inferior vena cava is 0.7%; for transposition, it is 0.3%. Even if they are obviously rare conditions, their presence must be suspected by practitioners as they can have important clinical consequences, may require changes in the surgery protocol, or can be associated with other congenital abnormalities.

Techniques for inferior turbinate reduction vary with various surgical methods, which differ in the approach of preservation of tissue from total turbinectomy to limited submucosal cauterization. Our preferred method to address hypertrophic inferior turbinate by mini turbinoplasty-tunneling technique are presented. Critical steps include creation of window in the inferior turbinate with a 4 mm microdebrider blade and removal of both inferior turbinate mucosal hypertrophy and bony component to convert a convex looking inferior turbinate to concave shape. This allows proper debulking of the entire medial aspect of the inferior turbinate and widening of the nasal valve area. Mini turbinoplasty-tunneling technique for hypertrophic inferior turbinates, is a safe method in achieving turbinate size reduction with minimal morbidity and long-term relief of nasal obstructive symptoms without added risk of complications.

Review

Authors: P R Cunningham, M B Foil

Lacerations of the inferior vena cava are associated with a high mortality and may be difficult to repair. The majority of injuries are due to penetrating trauma. Rapid transportation to definitive surgical care with effective resuscitation may improve mortality. Surgical management includes adequate treatment of hypovolemic shock due to blood loss. Placement of intravenous infusion sites below the level of the diaphragm may be effective. Operative control of the inferior vena cava can be accomplished by directed digital compression followed by a proximal and distal control. Injuries of the inferior vena cava above the level of the renal veins are associated with an increased mortality. Retrohepatic and subdiaphragmatic injuries are highly lethal. This article discusses appropriate surgical approaches for repair of the inferior vena cava above and below the diaphragm.

The prevalence of posterior inferior tibiofibular ligament and inferior tibiofibular transverse ligament injuries in syndesmosis-injured ankles evaluated by oblique axial magnetic resonance imaging: a retrospective study.

Authors: Kousuke Shiwaku, Atsushi Teramoto, Kousuke Iba...

BACKGROUND

Transverse ligament and posterior inferior tibiofibular ligament injuries have not been investigated till date because these are difficult to evaluate using standard magnetic resonance imaging. This study aimed to investigate the prevalence of transverse ligament and posterior inferior tibiofibular ligament injuries in syndesmosis-injured ankles using oblique axial magnetic resonance imaging.

METHODS

The patients who were diagnosed with syndesmosis injury using magnetic resonance imaging (MRI) within 7 days of the trauma were included. Patients with concomitant fractures were excluded. A total of 34 patients (1 woman and 33 men) with an average age of 22 years (range, 14-64 years) were included. The anterior inferior tibiofibular, interosseous, transverse, and posterior inferior tibiofibular ligaments were classified as intact, partial tear, or complete tear using usual axial and oblique axial MRIs.

RESULTS

There were 8 (23.5%) ankles with an intact, 21 (61.8%) ankles with a partially torn, and 5 (14.7%) ankles with a complete tear of transverse ligament. There were 20 (58.8%) ankles with an intact, 12 (35.3%) ankles with a partially torn, and 2 (5.9%) ankles with a complete tear of posterior inferior tibiofibular ligament. Overall, 50% of the transverse ligament injuries occurred without posterior inferior tibiofibular ligament involvement.

CONCLUSIONS

The oblique axial magnetic resonance imaging scan revealed that the prevalence of transverse ligament and posterior inferior tibiofibular ligament injuries in syndesmosis-injured ankles were 76.5 and 41.2%, respectively.

Congenital heart disease comprises one of the largest groups of congenital defects, affecting approximately 1% of births. Advances in pre- and postoperative critical care treatment as well as surgery and interventional procedures have improved survival rates, but treatment and long-term care of children with complex congenital heart disease remains challenging, and is associated with a number of complications.Here, we report on a 17-month-old infant with congenital univentricular heart disease who devloped post-operatively inferior vena cava (IVC) thrombosis. IVC thrombosis was confirmed by a bedside contrast media study (X-ray) demonstrating collateral paravertebral circulation along the paravertebral sinuses bilaterally into the azygos and hemiazygos vein ("rope ladder sign"), with no contrast media detected in the IVC. The infant was subsequently started on aspirin and clopidogrel.
