Diagnosis,treatment and prevention of type 2 diabetes mellitus in children and adolescents

During the last two decades, there have been several reports of an increasing incidence of type 2 diabetes mellitus (T2DM) in children and adolescents, especially among those belonging to minority ethnic groups. This trend, which parallels the increases in prevalence and degree of pediatric obesity, has caused great concern, even though T2DM remains a relatively rare disease in children. Youth T2DM differs not only from type 1 diabetes in children, from which it is sometimes difficult to differentiate, but also from T2DM in adults, since it appears to be an aggressive disease with rapidly progressive β-cell decline, high treatment failure rate, and accelerated development of complications. Despite the recent research, many aspects of youth T2DM still remain unknown, regarding both its pathophysiology and risk factor contribution, and its optimal management and prevention. Current management approaches include lifestyle changes, such as improved diet and increased physical activity, together with pharmacological interventions, including metformin, insulin, and the recently approved glucagon-like peptide-1 analog liraglutide. What is more important for everyone to realize though, from patients, families and physicians to schools, health services and policy-makers alike, is that T2DM is a largely preventable disease that will be addressed effectively only if its major contributor (i.e., pediatric obesity) is confronted and prevented at every possible stage of life, from conception until adulthood. Therefore, relevant comprehensive, coordinated, and innovative strategies are urgently needed.     

Gallbladder Findings after Cholecystectomy in Morbidly Obese Patients

Morbidly obese patients constitute a high risk group for the development of gallbladder disease. In our series 70 consecutive patients underwent vertical gastroplasty in an effort to manage morbid obesity. The mean age was 37 years (range 20-60), and the mean excess body weight was 92 kg (range 52-265). Six patients (8.5%) had undergone cholecystectomy before bariatric surgery because of symptomatic cholelithiasis. The remaining 64 patients underwent cholecystectomy at the time of vertical gastroplasty. Ninety-seven percent of the removed gallbladders had gross or histologic abnormalities, including cholelithiasis 18.5% (13 patients), and cholesterolosis 31% (22 patients). Histologically, chronic cholecystitis was present in all patients with cholelithiasis and cholesterolosis. Chronic cholecystitis alone was found in 27 patients (38.5%) and only two patients (3%) had normal findings. The mean excess body weight of the patients with cholesterolosis (96 kg) was not significantly greater than that of patients with cholelithiasis (89 kg) or chronic cholecystitis (88 kg). Our findings suggest that cholecystectomy should be performed in all morbidly obese patients concomitant with vertical gastroplasty.     

Tuberculosis notifications in Australia, 2003.

The National Notifiable Disease Surveillance System (NNDSS) received 982 tuberculosis (TB) notifications in 2003, of which 947 were new cases, 33 were relapses and two were cases with unknown history. The incidence of TB in Australia has remained at a stable rate since 1985 and was 4.9 cases per 100,000 population in 2003. The high-incidence groups remain people born overseas and Indigenous Australians at 19.9 and 8.7 cases per 100,000 population, respectively. By contrast the incidence in non-Indigenous Australians was 0.9 per 100,000. Comparison of the 2003 TB notification data against the performance indicators set by National Tuberculosis Advisory Committee highlights that enhanced TB control measures should be considered among these high-risk groups.     

Oral Fine Motor Control of Teeth Treated with Endodontic Microsurgery: A Single-Blinded Case-control Study

IntroductionPeriodontal mechanoreceptors (PMRs) are refined neural receptors present in abundance at the root apex and have a pivotal role in oral fine motor control. This case-control study aimed to evaluate the oral fine motor control of teeth treated with endodontic microsurgery (EMS) in comparison with the control teeth using a standardized behavioral biting task.MethodsFourteen eligible participants performed 5 trials of an oral fine motor control task that involved holding and splitting half of a peanut positioned on a force transducer with their EMS treated tooth and its contralateral control incisor tooth (28 teeth in total). The outcome variables were the mean food holding force, intra- and intertrial variability of the holding force, food splitting force, splitting duration, and the frequency of the stepwise splitting phase. The data were analyzed with parametric and nonparametric tests.ResultsThe results showed no statistically significant differences in the holding force, inter- and intratrial variability of the holding force, splitting force, or splitting duration between the teeth treated with EMS and the control (P > .05). However, there was a significantly higher frequency of stepwise ramp increase during the splitting phase with EMS treated teeth compared with the control (48% and 37%, respectively; P < .05).ConclusionsEMS treated teeth showed similar force regulation and oral fine motor control as the contralateral control. The findings of this study suggest that EMS treatment does not perturb the sensory information of PMRs and maintains the force regulation and oral fine motor control of the teeth.     

A record of skin creases and folds

The skin creases of the human body are features of great anatomical, morphological, and surgical interest and important for the maintenance of the contour of each anatomic area. In the literature, when referring to a skin crease, there is variation of terms used other than “crease,” such as “fold” and “sulcus,” but these terms do not accurately reflect their histology structure nor their function. In the review of literature, a record of the creases of the human body for each anatomic area, including the synonyms that are used for each crease in the literature, has been attempted. The skin crease as a fixed and permanent line, according to their histology, is related to connective tissue attachments with the underlying structures or extensions of the underlying muscle fibers in the dermis of the crease site. The skin fold is characterized by skin redundancy that is responsible partly, often in combination with connective tissue attachments, for the skin crease. It is essential to use appropriate terms that accurately reflect the anatomic structure and histology when referring to the skin lines.     

Transthoracic Repair of Asymptomatic Morgagni Hernia in an Adult

Morgagni hernia represents a rare type of diaphragmatic hernia which usually occurs on the right side, in the anterior mediastinum. Predisposing factors of Morgagni hernia include pregnancy, obesity or other causes of increased intraabdominal pressure, and a history of trauma. Most of adults diagnosed with a foramen of Morgagni are asymptomatic. We report a case of an overweight 23-year-old asymptomatic patient with a Morgagni hernia incidentally diagnosed on chest x-ray. There was a satisfactory result after the repair by a transthoracic approach.
