An Overview of Five-Year Survival in Rectal Cancer in Relation to Lymph Node Status

Introduction: Lymph node metastasis is regarded as an important prognostic factor for predicting disease recurrence and survival in patients with colorectal cancer. Several studies suggest that the lymph node ratio has a greater importance in survival than the number of metastatic lymph nodes. The scope of this study is to examine the 5-year survival of rectal cancer patients, examining several prognostic factors with emphasis on lymph node status. Material and Methods: A retrospective study was conducted at single surgical clinic from Romania, using data from patients who have been treated for rectal cancer between January 2009 and December 2014. Patient present status and regarding the multimodal treatment was assessed through telephonic method, data was extracted from the electronic database of the clinic and histopathological reports. Results: A total number of 144 patients affected by rectal cancer were assessed. Statistical analysis of the variables showed that age (p=0.001), T stage(p=0.049), N stage (p=0.005), LNR (p=0.006), type of surgery (p 0.001), presence of vascular invasion (p 0.001), metastases (p 0.001), to be significant prognostic factors for survival. Conclusions: The 5-year survival of the patients we included in the study was 63,9%. Nodal status, expressed by lymph node ratio proved to be a significant prognostic factor of patient survival.

[Experimental study on the resistance to intraluminal pressure between handsewn and stapled anastomosis. In vitro experimental study]

Intoduction and aim: The aim of the study was to compare the resistance to pressure of stapled and manually handsewn intestinal suture lines on in vitro pig intestine model.

METHOD

We performed different types of stapled and manual sutures and the pressure level was measured using a differential pressure manometer.

RESULTS

Although the hand-sewn end-to-end suture turned out to be the most resistant to pressure, statistical analysis revealed no significant differences compared to stapled suture (p = 0.49). In stump closure techniques, we observed a statistically high significance in resistance to pressure in the favour of manual stump closure (p = 0.004).Regarding side-to-side sutures we did not find any statistically significant differences in resistance to pressure between the techniques (p = 0.06).

CONCLUSION

We can conclude that regarding the stump closure, the most resistant to pressure is the hand-sewn procedure, but in the other types of anastomosis, no significant differences was found between the stapled and hand-sewn techniques. Orv Hetil. 2017; 158(42): 1674-1680.

Superficial basal cell carcinoma treated with 70% trichloroacetic acid applied topically: a case study

Background

Basal cell carcinoma (BCC) is the most common form of skin cancer, affecting millions of people worldwide. The treatment concept for BCCs is the surgical one, but it is costly, as such, searching for alternative medical therapeutics is justified.

Aim

To highlight the efficacy of high concentration (70%) trichloroacetic acid (TCA) as a choice therapy for low-risk BCC.

Method and patient

Authors present, for the first time, the use of a high concentration TCA applied once a week for 2 consecutive weeks with a toothpick, on a patient with BCC on the right preauricular area.

Results

On examination 4 weeks later, the lesion was not clinically and dermatoscopically evidenced.

Conclusion

High concentration TCA could be an effective and safe, non-invasive choice of therapy for low-risk BCC, easy to perform, not expensive, with good cosmetic results, especially for patients who are not likely to undergo invasive or expensive treatments.

Nail Damage (Severe Onychodystrophy) Induced by Acrylate Glue: Scanning Electron Microscopy and Energy Dispersive X-Ray Investigations

BACKGROUND

Scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) techniques have been used in various fields of medical research, including different pathologies of the nails; however, no studies have focused on obtaining high-resolution microscopic images and elemental analysis of disorders caused by synthetic nails and acrylic adhesives.

METHODS

Damaged/injured fingernails caused by the use of acrylate glue and synthetic nails were investigated using SEM and EDX methods.

RESULTS

SEM and EDX proved that synthetic nails, acrylic glue, and nails damaged by contact with acrylate glue have a different morphology and different composition compared to healthy human nails.

CONCLUSIONS

SEM and EDX analysis can give useful information about the aspects of topography (surface sample), morphology (shape and size), hardness or reflectivity, and the elemental composition of nails.

[Endosalpingiosis of the axillary lymph nodes--primary or metastatic tumour?]

The involvement of extra-abdominal sites by serous ovarian tumours of low malignant potential is extremely rare. In this paper we present the case of a 33 years old woman, diagnosed with atypical endosalpingiosis in the axillary lymph nodes before the diagnosis of a bilaterally ovarian serous tumour of low malignant potential. The occurrence of axillary lymph nodes involvement associated with serous tumours of the ovary could be explained by the presence of circulating serous cells that remained dormant for a period of time or by the development of an independent primary tumour from glandular inclusions in axillary lymph nodes. The recognition of the occurrence of axillary atypical endosalpingiosis in association with serous tumours of the ovary is important to avoid misdiagnosis. It is better to define these lesions as secondary serous papillary involvement.
