Quilting sutures compared with sponge packing in septolplasty and turbinoplasty

INTRODUCTION

There is a lack of consensus regarding the need for nasal packing after a septoplasty. The use of nasal packing has been proposed to reduce bleeding, synechiae and haematomas. Despite these advantages evidence is scant to support postoperative packing. Furthermore, packing is not an innocuous procedure and can cause complications.

OBJECTIVE

The purpose of this study was to investigate the efficacy of quilting sutures compared with sponge nasal packing on haemostasis, haematomas and wound healing following septoplasty.

MATERIAL AND METHODS

Seventy-six patients with nasal septum deviation requiring septoplasty and turbinoplasy with radiofrequency were included. Following surgery, fifty patients were selected randomly for septoplasty with one quilting suture. And twenty-six patients had sponge nasal packing. Haemostatic properties, formation of haematomas, formation of synechiae, the patients' pain and bleeding on removal of the packing were evaluated.

RESULTS

Both techniques were equally effective in the control of postoperative bleeding, haematoma and synechiae formation following septoplasty. Sponge packing was associated with significant pain and bleeding on removal.

CONCLUSION

The use of quilting sutures like sponge packing is efficient in controlling bleeding, synechiae and haematomas after septoplasty and turbinoplasty.

Copper(II) complex-loaded castor oil-based nanostructured lipid carriers used against Mycobacterium tuberculosis : Development, characterisation, in vitro and in vivo biological assays

A copper(II) complex-loaded castor oil-based nanostructured lipid carrier was evaluated to enhance the poor water solubility of antimicrobial compounds, improving their biological properties and antimicrobial activity against Mycobacterium tuberculosis. Nanostructured lipid carriers were composed of the castor oil, polyoxyethylene 40 stearate and caprylic/capric triglyceride, poloxamer 407, cetyltrimethylammonium bromide and three different copper(II) complexes. The systems were ultrasonicated at an amplitude of 8% for 20 min and an ice bath was used throughout the procedure. The blank nanostructured lipid carrier (F5) and nanostructured lipid carriers loaded with copper(II) complex 1, 2 and 3 (F5.1, F5.2 and F5.3, respectively) for 45 days presented values of mean diameter, poly dispersity index and zeta potential ranging from 186 to 199 nm, 0.14 to 0.2 and 24 to 30 mV, respectively. Atomic force microscopy indicated that the nanostructured lipid carriers were distributed at the nanoscale, corroborating the mean diameter data. Differential scanning calorimetry determined the melting points of the constituents of the nanostructured lipid carriers. The antimicrobial activity of copper(II) complexloaded F5 against M. tuberculosis H₃₇Rv showed better anti-tuberculosis activity than the free complexes. In vivo biological assays of complex-loaded F5 demonstrated reduced toxicity. Our results suggest that nanostructured lipid carriers could be a potential nanotechnological strategy to optimise tuberculosis treatment.

Low validity of predictive equations for calculating resting energy expenditure in overweight and obese women with polycystic ovary syndrome

BACKGROUND

Predictive equations are the main clinical tools for determining resting energy expenditure (REE). However, their adequate use in overweight and obese individuals is unclear. Thus, we investigated the best predictive equations for estimating REE in overweight and obese women with polycystic ovary syndrome (PCOS).

METHODS

Eleven analyses were performed with prediction equations (pREE) based on anthropometric parameters in 30 overweight or obese women with PCOS without other chronic diseases. The measured REE (mREE) was calculated by indirect calorimetry. The validity of the equations was investigated by comparison, accuracy and agreement tests between pREE and mREE at both the individual and group level.

RESULTS

Four analyses were similar to those of mREE, and smallest mean differences were observed for the World Health Organization/Food and Agriculture Organization of the United Nations/United Nations University (WHO/FAO/UNU) considering weight (W) [0.07 (1.13) MJ (16 [270] kcal)]. Individual accuracy was greater than 50% for Harris and Benedict, Müller and Lazzer equations. The percentage of REE underestimation ranged between 16.7% and 73.3%, whereas higher rates of overestimation were observed in the De Luis (66.7%) and Ireton-Jones (43.3%) equations. Mean bias at the group level was lowest in the WHO/FAO/UNU W and WHO/FAO/UNU considering weight and height (WH), Müller and Lazzer equations (-2.8 to 0.5). The WHO/FAO/UNU W and WHO/FAO/UNU WH formulas were optimal in individual agreement (33.3%).

CONCLUSIONS

FAO/WHO/UNU W equations may estimate the REE in overweight and obese women with PCOS. However, the low individual accuracy and agreement in relation to mREE suggest caution regarding when to use the formula to perform an individual nutritional plan.

[Primary pleomorphic adenoma (chondroid syringoma) of the external auditory canal. Case report and literature review]

Chondroid syringoma of the external auditory canal is an extremely rare neoplasm, representing the cutaneous counterpart of pleomorphic adenoma of salivary glands. This tumour is thought to derive from the apocrine duct of the folliculo-sebaceous-apocrine unit. We report the case of a 68-year-old male in whom the clinical and radiological examinations showed a well-circumscribed tumour limited to the external auditory canal. The diagnosis was confirmed by histologic examination. We also reviewed the literature.

Patterns of serologic response to human immunodeficiency virus type 1 (HIV-1) in Brazilians with different clinical forms of HIV infection

In order to investigate the IgG HIV-1 antibodies reactivity to structural components of the virus, 85 sera from infected Brazilians, comprising the total spectrum of HIV infection, were analysed by Western blot assay. The sera were confirmed as being positive to HIV with enzyme linked immuno assay (ELISA) and indirect immunofluorescence (IIF). Although the sera from patients reacted less intensively to the gag polypeptide of 55 KDa, no distinctive antigen reaction patterns were observed between sera patients with different clinical forms. Because of the higher frequency of reactivity to the gag p24 in AIDS patients, the patterns of anti-HIV IgG responses are similar to those observed in their African counterparts.
