Free floating thrombosis of internal carotid artery (FFT-ICA) is one of the rare problems among carotid artery diseases which can lead to stroke in adults. Owing to limited cases of FFT-ICA there is not a worldwide accepted consensus on management of FFT-ICA, but some recurrences after medical management have been reported in the literature. A-25-year old woman was referred to hospital with sudden onset aphasia and right sided hemiparesis. Carotid duplex ultrasonography showed an iso-echogenic thrombus ranged about 5×10mm partially attached to arterial wall of the right internal carotid artery. It was floating in accordance with the heartbeat. Anticoagulation therapy was initiated and subsequently she underwent an urgent operation. To explore the etiology of her problem, various lab tests were carried out; the results showed markedly elevated levels of lupus...

In this retrospective survey, medical records of patients referred to the Shohada-e Tajrish hospital during 2001 to 2005 were reviewed and subjects with definite diagnosis of SCC were included. Required data were extracted from the patients' records, and their prepared paraffin-embedded tissue blocks were collected under supervision of two pathologists. Immunohistochemistry (IHC) analysis was performed at the Firoozgar hospital in Tehran, Iran. The studied population included 20 men (74%) and 7 women (26%). The mean age at diagnosis was 58 ± 22. Results showed significantly higher survival rates in women compared to men (85.7 vs. 40%) (p = 0.001) and in pati...

This coexistence has rarely been reported in literatures. We report a case of 64-year-old woman who has diagnosed with prepyloric poorly-differentiated diffuse signet-ring cell type adenocarcinoma and has undergone an elective D2 total gastrectomy. During operation another mass in fundic body region has found. The pathologic examination of the mass has shown GIST. Immunohistochemical staining for CD117 and Desmin was positive whilst that for S100 was negative. This case reports the simultaneous two tumors development of different histotypes and natures in the same organ.

The best permanent access is AVF (arterio venous fistula). Use of a technique to create AVF with better patency seems to be logical. Objectives: The present study aimed to compare the efficacy rate of AVFs using two different anastomosis methods; Side to Side (STS) versus End to Side (ETS) and to determine whether the different approaches render any preferences or complications. Patients and Methods: Sixty end stage renal disease (ESRD) patients were included in this clinical trial in two assigned groups of 30 patients. In one group end to side method to create AVF was used while in the other group Side to Side technique was applied for access in surgery. Both groups were followed for duration of 6 months to assess patency. For evaluating the quantitive variables, t-test was used while qualitative variables were measured using the chi-square and Fisher`s exact tests. Results: In the 6 months duration, 6 patients (20%) in the STS (side to side) group and 5 patients (16.6%) in the ETS (end to side) group experienced a non-functional AVF. In the ETS group the failure was generally a result of thrombosed access while in the STS group, 4 out of 6 patients with complications, experienced thrombosis while the other 2 patients had venous hypertension. The total failure rate was 18.3% and during the 6 months of follow up no significant difference was detected in the efficacy rate. Nevertheless, in case of longer follow ups, different outcomes could be seen. Conclusions: This study demonstrated that there was no significant statistical difference between the functional patency rates of fistulae placed by STS or ETS methods.

Hemodialysis is the most accepted treatment to maintain body's fluid/electrolyte homeostasis at the terminal stages of the disease. Permanent hemodialysis catheter (permicath) may be inserted blindly or by fluoroscopic guidance. This study aimed to compare the early function and complications between fluoroscopic guidance and blindly insertion of permanent hemodialysis catheter. Methods: This prospective randomized clinical trial was undertaken in the emergency department of Modarres hospital in Tehran, Iran during 2014 and 2015. Patients who needed catheter due to renal failure entered the study. Patients who needed emergency dialysis and those who could not wait for permicath were excluded. Patients were randomly assigned into 2 groups, under fluoroscopic guidance and blindly catheter insertion. Data were collected using a questionnaire and a checklist related to function (after 24 hours and 1 month), a need to exchange the catheter and the early adverse effects such as pneumothorax, hemothorax, and vascular injury. Results: A total of 101 patients were enrolled in this trial. Early dysfunction (blind group = 5), a need for catheter exchange (blind group = 2), pneumothorax (blind group = 2), vascular injury (blind group = 1) were recorded but the difference between the two groups was not statistically significant (P > 0.05). Conclusion: We did not observe a significant difference between the placement of permicath by fluoroscopic or blind method. However, more studies with larger groups are recommended.

of appendicitis increases with increased lymphatic tissue with the maximum prevalence at
the beginning of adulthood. Owing to the high prevalence of appendectomy, patients will
be benefited from a better method with improvement of surgical site and management of
postoperative pain and infection. Subcuticular repair method due to better scar formation and
less pain is preferred to the routine repair method, if the infection rate is comparable.
Methods: The current study was conducted on appendectomy candidates in 2017. After
providing the necessary explanations, the interested patients signed the informed consent
forms and voluntarily participated in the study. The subjects were randomly assigned into two
groups of randomized clinical trial with parallel design and 1:1 ratio. The sample size was 120
individuals based on previous studies. Subjects were assigned into two groups of 105 subjects
each: the first group as subcuticular and the second group as transdermal accordingly. Then,
they were studied and followed up.
Results: One week after operation, 8.5% of subcuticular and 5.7% of transdermal repairs
developed localized infection, and no significant difference was observed between the two
groups. One week after surgery in the first group, 10% had no pain, 36% mild pain, 27%
moderate pain, and 27% severe pain. In the second group, 7% had no pain, 36% mild pain,
30% moderate pain, and 27% severe pain. Therefore, there was no significant difference
between two groups in this regard.
Conclusion: There was no significant difference in the surgical wound infection rate between
two methods. Accordingly, subcuticular repair was suggested as the preferred method owing
to its better scar formation.
