The first case of myxoinflammatory fibroblastic sarcoma affecting the maxillary bone

Myxoinflammatory fibroblastic sarcoma (MIFS) is rare and malignant soft-tissue neoplasms that typically present in the extremities. In the literature, MIFS has been reported in the groin, back, neck, nose, and temporal regions in addition to the extremities. We report a case of MIFS presenting with the complaints of nasal bleeding, purulent nasal discharge, and swelling on the right side of his face. Polypoid tissues protruded from the middle meatus were observed and initial diagnosis was inverted papilloma. The painless tumor was initially mistaken for low-grade myxofibrosarcoma in biopsy. Maxillectomy was performed and made the rare diagnosis of MIFS. Fibroblastic proliferation with extensive local spread from subcutaneous tissue to the epithelium of the maxillary sinus mucosa, maxillary bone, and especially along the bone marrow was observed. To the best of our knowledge, this is the first reported case of MIFS involving the maxillary bone.

The effects of ankaferd blood stopper on the recovery process in an experimental oesophageal perforation model

BACKGROUND

Oesophageal perforation is a life-threatening pathology that is generally treated conservatively; however, surgical procedures are frequently performed. A topical haemostatic agent, Ankaferd Blood Stopper (ABS), also has beneficial wound-healing effects.

AIMS

This study aimed to determine the effects of ABS following experimental oesophageal perforations.

STUDY DESIGN

Animal experiment.

METHODS

The experimental rats were classified into 6 groups (with 7 rats in each group). Pairs of groups (primary repair alone and primary repair + ABS) were terminated in the 1(st), 2(nd), and 3(rd) weeks following injury. The oesophageal perforations, which were 8-10 mm in length, were created using a nasogastric tube. The perforation sites were repaired with a 6-0 polyglactine thread in the primary repair groups. Additionally, ABS was sprayed over the perforation site in the treatment groups. Each oesophagus was evaluated histopathologically.

RESULTS

There were fewer microabscesses and areas of necrosis in the ABS groups compared with the primary repair groups. The histopathological evaluation revealed that the ABS groups had less inflammation and more re-epithelisation compared to the primary repair groups (p=0.002 and p=0.003, respectively). Fibrosis in the ABS groups was moderate in the 2(nd) week and mild in the 3(rd) week. Comparing the groups with respect to the time intervals, only the 1(st) week groups showed a significant difference in terms of re-epithelialisation (p=0.044).

CONCLUSION

Topical ABS application on the repaired experimental oesophageal perforation regions led to positive wound-healing effects compared with the rats that were administered the primary repair alone.

A combination of plasma DAO and citrulline levels as a potential marker for acute mesenteric ischemia

INTRODUCTION

There is no valid and reliable diagnostic test for early diagnosis of acute mesenteric ischemia (AMI). The aim of this study was to measure the plasma levels of diamine oxidase (DAO) and citrulline in AMI to gain insight into its early diagnosis.

MATERIAL AND METHODS

A total of 21 Wistar albino rats were divided into three groups, that is, control group, short-term ischemia group, and prolonged ischemia group. The superior mesenteric artery was occluded for 15 min in the short-term ischemia group and for 12 h in the prolonged ischemia group. Twelve hours later, the experiment was terminated and plasma DAO and citrulline levels were measured. Intestinal tissue was evaluated for the histopathological changes.

RESULTS

Compared to the control group, the short-term and prolonged ischemia groups showed significant increases in the plasma levels of DAO, whereas the plasma citrulline levels decreased significantly. Prolonged ischemia caused a larger increase in the plasma DAO levels and a larger decrease in the plasma citrulline levels compared to the short-term ischemia (p=0.011 and p=0.021, respectively). Intestinal damage was shown to develop more in the prolonged ischemia group (p=0.001).

CONCLUSION

In the early period of AMI, the plasma DAO levels increase while citrulline levels decrease, and the extent of these changes depends on the duration of ischemia.

The evaluation of topical administration of Bellis perennis fraction on circular excision wound healing in Wistar albino rats

CONTEXT

Bellis perennis L. (Asteraceae) has been used traditionally in the treatment of bruises, broken bones, and wounds by European people.

OBJECTIVE

To investigate the wound healing activity of B. perennis flowers in Wistar albino rats.

MATERIALS AND METHODS

Dried B. perennis flowers were extracted with ethanol, then fractioned with n-butanol and an oinment was prepared. Twelve male adult Wistar rats were used. Six wounds were created for each animal by using circular excision wound model. The first two wounds were treated topically with HOTBp (hydrophilic ointment treatment containing n-butanol fraction). The second two wounds were control group and not treated with anything. The third two wounds were treated only with HOT (hydrophilic ointment treatment without n-butanol fraction). Treatments were applied once a day and lasted for 30 days. Wound samples were excised on days 5(th), 10(th) and 30(th). The percentage of wound healing was calculated by Walker's formula after measurement of the wound area and the tissue samples were examined histopathologically.

RESULTS

The percentages of wound closure (HOTBp: 100%; HOT: 85% and control: 87%) and histopathological observations showed that there were statistically significant differences between HOTBp, HOT and control groups (p < 0.05) at 30(th) day.

DISCUSSION AND CONCLUSION

Topically administered ointment prepared from the n-butanol fraction of B. perennis flowers has a wound healing potential without scar formation in circular excision wound model in rats. Thus, traditional usage of wound healing activity of B. perennis was scientifically verified for the first time.

Submandibular gland pleomorphic adenoma in a seven-year-old child: a case report

Salivary gland neoplasms are rare in the pediatric age group. Pleomorphic adenomas in the submandibular gland are rarer. In this article, we present a seven-year-old female with a slowly growing mass in her right submandibular area. The firm, mobile and painless mass was about 2x3 cm in size and with bimanual palpation it was indiscriminated from the submandibular gland. Magnetic resonance imaging with contrast revealed a heterogeneous and minimally lobulated mass within the submandibular gland with clearly defined borders. Fine needle aspiration biopsy revealed a diagnosis of pleomorphic adenoma and we performed right submandibular gland excision under general anesthesia. The histopathological diagnosis was pleomorphic adenoma with sparse mitotic figures that may be interpreted as having a potential of malignant transformation. This patient who was followed up for one year without any complication is to our knowledge the youngest case cited in the English-language literature.
