Clinical utility of dorsal sural nerve conduction studies in healthy and diabetic children.

OBJECTIVE: Monitoring of the dorsal sural sensory nerve action potential (SNAP) is a sensitive method for detection of peripheral neuropathies. We tried to determine the normal dorsal sural nerve conduction values of the childhood population and assessed the clinical utility of this method in diabetic children who have no clinical sign of peripheral neuropathy. METHODS: In the study, 36 healthy and 27 diabetic children were included. In all subjects peripheral motor and sensory nerve studies were performed on the upper and lower limbs including dorsal sural nerve conduction studies. RESULTS: The dorsal sural SNAP mean amplitude was 8.24+/-3.08 microV, mean latency was 2.47+/-0.48 ms, mean sensory conduction velocity was 41.63+/-5.43 m/s in healthy children. Dorsal sural SNAPs were absent bilaterally in one diabetic patient. In the other 26 diabetic patients, the mean dorsal sural nerve distal latency was longer (2.93+/-0.63 ms, P = 0.004), mean SCV was slower than in healthy subjects (36.68+/-7.66 m/s, P = 0.005). However, dorsal sural nerve amplitude was not different between the groups. A dorsal sural nerve latency of more than 2.9 ms had a sensitivity of 50% and a specificity of 75%. A dorsal sural nerve velocity of less than 36 m/s had a sensitivity of 54% and a specificity of 92%. CONCLUSIONS: We designated the reference values of the dorsal sural nerve in healthy children. In addition, our findings suggest that dorsal sural nerve conduction studies may have value to determine neuropathy in the early stages in children with diabetes. SIGNIFICANCE: The dorsal sural nerve conduction studies in diabetic children may have value to determine the neuropathy in its early stages.     

Serum lipid levels in psoriasis

A predisposition to occlusive vascular diseases has been reported in patients with psoriasis and it has been suggested that some of these patients have some disorders of lipid metabolism. In this study, serum lipid levels were investigated in psoriatic patients to explore to the knowledge of this relationship. One hundred psoriatic patients and 100 non- psoriatic controls were included in the study. Total cholesterol, triglyceride, high-density lipoprotein-cholesterol (HDL-cholesterol), low-density lipoprotein-cholesterol (LDL-cholesterol), and very low-density lipoprotein-cholesterol (VLDL-cholesterol) levels were measured. In patients with psoriasis, total cholesterol and LDL-cholesterol levels were found to be significantly higher than those of controls. No significant differences were found in the other parameters. We concluded that psoriatic patients should be evaluated and followed up for the risk of hyperlipidemia and obstructive vascular diseases.

Body mass index percentiles among adolescent girls living in Edirne, Turkey

BACKGROUND: Body mass index (BMI) is the simplest way to measure obesity; therefore, it is chosen by many authorities as a screening method for adolescent obesity. Body mass index is positively correlated with the complications of childhood and adolescent obesity, such as hypercholesterolemia, insulin resistance, hyper-tension and long-term development of cardiovascular diseases. The aim of the present study was to produce percentile curves for bodyweight, height and BMI in a representative sample of adolescent girls living in urban and rural areas of Edirne, Turkey, and to compare these percentile curves with curves from other countries. METHODS: The present study was a cross-sectional study, including a representative sample of 1687 adolescent girls from rural and urban areas of Edirne, who were evaluated between May and July 2001. Bodyweight and height were measured using standard procedures. Body mass index (kg/m2) was calculated as the ratio of bodyweight to body height squared. Smoothed percentiles for these variables were calculated using polynominal regression models. Crude weight, height and BMI percentile values, as well as smoothed percentile curves are presented. RESULTS: Body mass index, weight and height reference curves for adolescent girls were produced. When we compared the BMI values of subjects in the present study with those of other countries, 85th and 95th percentiles of BMI in the present study were found to be generally lower than those for other ethnicities. CONCLUSION: Our findings show ethnic differences in BMI among adolescent girls. It will be usefull for each country to produce its own BMI percentiles.     

Fatal aluminum phosphide poisonings in Tirana (Albania), 2009 – 2013

Background

Acute poisonings particularly through pesticides have become a major public health concern in Albania during the last decade.

Findings

The number of fatalities due to aluminum phosphide intoxications was more than doubled during a five year-period from 2009 to 2013, and a cluster of suicides perpetrated with Phostoxin was registered. Several factors are accountable for such a phenomenon, including the fact that aluminum phosphide agents are freely available in the Albanian market, their price is extremely low and they are sold without any legal restriction. The mass media unfortunately warranted an emulating effect to dramatic intoxications, which gained by such means the notoriety of a secure lethal weapon.

Conclusions

Our experience with more than three hundred intoxications with aluminum phosphide agents in the last five years, showed that a considerable delay from the moment of exposure (mainly through ingestion) to specialized medical help seeking, created a considerable obstacle for a successful treatment of cases, and eventually for the survival of patients. The lack of a specific antidote adds further challenges to all these exposures. The need for public health policies aiming at prevention, awareness, and possibly the substitution of Phostoxin or other aluminum phosphide pesticides with less dangerous agents is formulated.     

Proposal of ecographic classification for seroma after laparoscopic ventral hernia repair

Introduction

Seroma is one of the most common complications after laparoscopic ventral hernia repair (LVHR), even if the incidence brought in literature is varying because definition and criterions of evaluation employed in the different studies are not always the same. This study proposes a classification for seroma after LVHR based on ultrasound findings, useful for an assessment of this complication.

Materials and methods

On 93 patients submitted to LVHR an ultrasound of the abdominal wall after 3, 7, 15, 21 and 28 days and subsequently at a distance of 3 and 6 months was performed postoperatively. At each control site, sonomorphology characteristics and size of seroma (if present) were noted.

Results

At the end of the study using ultrasound findings obtained, a classification scheme for seroma articulated into three groups based on the parameters detected (site, sonomorphology character and volume) was developed, each of which is subdivided into five different classes to which a precise score is assigned. From the sum of the scores assigned, a value (between 3 and 15) that represents a prognostic index (PI) is obtained. A low PI is typical of small asymptomatic seroma that resolves spontaneously in a short time and without the need for invasive therapies; a high PI is typical of more or less symptomatic voluminous seroma that tends to persist for long periods and which often requires an interventional therapeutic approach.

Conclusions

This proposed classification helps to perform a precise nosological assessment of seroma after LVHR, allowing the surgeon to predict the clinical and temporal evolution of this complication and to plan appropriate therapy from time to time. Furthermore this classification can represent a tool to assess the uniqueness of seroma formation in relation to surgical technique used, to the type of material employed and to the method of mesh fixing.     

The Abbé island flap for the reconstruction of severe secondary cleft lip deformities

Primary repair of the cleft lip is often associated with secondary deformities, which require revision and secondary reconstruction. Patients with one or all of the following, a tight lip restricting use of orthodontic appliances, absence of a Cupid's bow, or absence of vermilion tubercle, were treated with the Abbé island flap. A triangular muco-musculo-cutaneous island flap was designed in the central segment of the lower lip. A full-thickness incision of skin, muscle, and mucosa was made in the midline of the upper lip, dividing the lip into two segments, and the island Abbé flap was inserted. One week after surgery, the pedicle of the island flap was divided and the inset of the flap completed. Sixty patients with severe secondary cleft lip deformities (36 males and 24 females) were treated. Good aesthetic and functional results were achieved during 1 to 17 years of follow-up. Insertion of the Abbé flap resulted in release of the tight upper lip and a new, inconspicuous scar. Use of orthodontic appliances was facilitated, and tightness of the tissue, which restricted the expansion of the alveolar process, was eliminated. Adequate tissue was transferred to the upper lip, which improved the bulk of the lip and vermilion tubercle. The retrusion of the midface and the projection of the upper lip were also improved, and the upper and lower lips became better balanced. Donor site morbidities were insignificant. Use of the Abbé flap in selected patients resulted in successful reconstruction of secondary cleft lip deformities.
