Abstract
BACKGROUND Diabetes-related skin ulcers provide a substantial therapeutic issue, sometimes leading to amputation, needing immediate practical treatments for efficient wound care. While the exact mechanisms are unknown, pyroptosis and deregulation of the unfolded protein response (UPR) are known to exacerbate inflammation. Nicotinamide Riboside (NR) and Resveratrol (RV), which are known for their Nicotinamide adenine dinucleotide (NAD+) boosting and anti-inflammatory properties, are being studied as potential treatments. The purpose of this study was to shed light on the underlying molecular mechanisms and explore the medical application of NR and RV in diabetic wound healing. METHODS 54 male Sprague-Dawley rats divided into control, diabetic (DM), Gel Base, DM-NR, DM-RV, and DM-NR + RV. Rats were orally administered 50 mg/kg/day of RV and 300 mg/kg/day of NR for 5 weeks. Following diabetes induction, their wounds were topically treated with 5 % NR and RV gel for 15 days. The wound closure rate, body weight, and serum lipid profiles were examined. Gene expression study evaluated UPR and pyroptosis-related genes (BIP, PERK, ATF6, IRE1α, sXBP1, CHOP, NLRP3, caspase-1, NFκB, and IL1-β) in wound tissues, alongside histological assessment of cellular changes. RESULTS NR and RV treatments greatly enhanced wound healing. Molecular investigation demonstrated UPR and pyroptosis marker modifications, suggesting UPR balance and anti-inflammatory effects. Histological investigation demonstrated decreased inflammation and increased re-epithelialization. The combination of NR and RV therapy had better results than either treatment alone. CONCLUSION This study shows that NR and RV have therapeutic promise in treating diabetic wounds by addressing UPR dysregulation, and pyroptosis. The combination therapy is a viable strategy to improving the healing process, providing a multimodal intervention for diabetic skin ulcers. These findings pave the way for additional investigation and possible therapeutic applications, giving hope for better outcomes in diabetic wound care.

Abstract
Theranostics nanoparticles (NPs) have recently received much attention in cancer imaging and treatment. This study aimed to develop a multifunctional nanosystem for the targeted delivery of photothermal and chemotherapy agents. Fe3O4 NPs were modified with polydopamine, bovine serum albumin, and loaded with DOX via a thermal-cleavable Azo linker (Fe3O4@PDA@BSA-DOX). The size of Fe3O4@PDA@BSA NPs was approximately 98 nm under the desired conditions. Because of the ability of Fe3O4 and PDA to convert light into heat, the temperature of Fe3O4@PDA@BSA NPs increased to approximately 47 °C within 10 min when exposed to an 808 nm NIR laser with a power density of 1.5 W/cm2. The heat generated by the NIR laser leads to the breaking of AZO linker and drug release. In vivo and in vitro results demonstrated that prepared NPs under laser irradiation successfully eradicated tumor cells without any significant toxicity effect. Moreover, the Fe3O4@PDA@BSA NPs exhibited the potential to function as a contrasting agent. These NPs could accumulate in tumors with the help of an external magnet, resulting in a significant enhancement in the quality of magnetic resonance imaging (MRI). The prepared novel multifunctional NPs seem to be an efficient system for imaging and combination therapy in melanoma.

Abstract
INTRODUCTION AND IMPORTANCE There are only a few case reports to date that have described patients with three or more multiple primary tumors. However, they have been reported more in the last decade, so a precise screening in patients with or without risk factors could be helpful in early diagnosis and treatment. This work has been reported in line with the SCARE criteria. CASE PRESENTATION Here, we presented a 44-year-old female patient without any history of smoking, alcohol consumption, or cancer in her family. She had three metachronous primary tumors; breast, thyroid, and gastric cancer, which had metastasized to both her ovaries and colon. She died in January 2023 due to complex pneumonia and septic shock. To our knowledge, this article is the second case in which breast, thyroid, and stomach cancer are reported together. CLINICAL DISCUSSION When it comes to Multiple primary malignancies (MPMs), not only screening in patients with risk factors should be considered, but patients without any other risk factors except current or past history of tumors should be screened precisely for early diagnosis and treatment. In this study, we discuss prevalence and causes of MPMs, prevalence of breast, thyroid, and stomach cancer, and also their possible relations with each other that may affect their occurrence. CONCLUSION Reporting other cases with MPMs by physicians could lead to establish an evidence based approach to these patients.

Abstract
Cirrhotic cardiomyopathy is a myocardial disease that may go undetected in the early stages due to peripheral vasodilatation. The aim of the study was to evaluate the electrocardiogram (ECG) and heart rate variability (HRV) after raising blood pressure by phenylephrine injection in rats with liver cirrhosis. Twenty male Sprague-Dawley rats were divided into the Sham and common bile duct ligation (CBDL) groups. After 44 days, animals were anesthetized and the right femoral artery and vein catheterized. After a steady-state period, a bolus injection of phenylephrine (PHE, 10 μg/μl/IV, baroreflex maneuver) was followed by a slow injection of PHE (100 μg/ml/5 min/IV, sustained maneuver). Rapid and slow injections of PHE resulted in a greater increase in mean arterial pressure (MAP) and a weaker bradycardia response in the CBDL group than in the Sham group. ECG analysis showed increased QT, QTc, JT, and T peak to T end in the CBDL group, which remained unchanged after PHE injection. On the other hand, the parasympathetic indices of the HF band and RMSSD, and the sympathetic index of the LF band after PHE injection were lower in the CBDL group than in the Sham group.ECG data indicated prolonged ventricular depolarization and repolarization, independent of blood pressure levels in cirrhosis. On the other hand, after PHE injection, the parasympathetic and sympathetic components of HRV decreased, regardless of the duration of elevated blood pressure. We suggest that HRV analysis can provide a useful approach to assess cardiac dysfunction associated with elevated blood pressure in cirrhosis.

Abstract
BACKGROUND Methanol-poisoning can be a challenging cause of mortality. Identifying the epidemiological, clinical, and para-clinical determinants of outcome in methanol-poisoning patients could be a step forward to its management. METHODS In this hospital-based cohort study, 123 methanol-poisoning patients were included. Data on background variables, details of methanol consumption, and laboratory assessments were recorded for each patient. Patients underwent brain CT scans without contrast. We evaluated the association of all gathered clinical and para-clinical data with patients' outcome and length of hospital stay (LOS). Independent association of potential determinants of death, and LOS were modeled applying multivariable logistic, and Ordinary Least Square regressions, respectively. Odds ratio (OR), and regression coefficient (RC), and their 95% confidence intervals (CIs) were estimated. RESULTS Most of the study population were male (n=107/123). The mean age of the participants was 30.3±9.1 years. Ninety patients (73.2%) were reported as being conscious on admission, and 34.3% of patients were identified with at least one abnormality in their CT scan. Level of consciousness (LOC) (OR: 42.2; 95% CI: 2.35-756.50), and blood pH (OR: 0.37; 95% CI: 0.22-0.65) were associated with death. Supratentorial edema (RC: 17.55; 95% CI: 16.95-18.16) were associated with LOS. CONCLUSION Besides LOC, patients with any abnormality in their brain CT scan on admission were found to be at higher risk of death, and patients with supratentorial edema were at risk of longer LOS. Brain CT-scan on admission should be considered as a part of the routine procedure during the management of methanol-poisoning.

Abstract
INTRODUCTION AND IMPORTANCE Osteoma is a benign, and usually asymptomatic bone tumor normally found in the skull and facial bones, although it can occasionally occur in the long bones and spine. CASE PRESENTATION In this article, we present a 49-year-old male patient who experienced progressive neck pain accompanied by left-sided radicular pain symptoms. Clinical investigation using various imaging techniques confirmed a bone-forming lesion located within the C1 vertebrae region. Treatment involved performing hemilaminectomy of C1 along with resection for complete removal of this extradural bone lesion, ultimately achieving symptom relief. Histopathological examination of the resected specimen leads to the diagnosis of osteoma. Along with reporting this case, we conducted a comprehensive literature review of the previously reported spinal osteoma cases. CLINICAL DISCUSSION Histopathological examination confirmed the diagnosis of osteoma. A comprehensive literature review was conducted, revealing 16 previously reported cases of spinal osteoma. Among these, only one case involved the C1 vertebra and presented similar neurological symptoms. The review underscores the rarity of spinal osteomas and the importance of surgical intervention for symptom relief. CONCLUSION Spinal osteomas are rare but should be considered in the differential diagnosis of patients presenting with neck pain and radicular symptoms. Surgical removal of the lesion is often necessary for symptom relief, as highlighted by our case and supported by the literature review. This case adds to the limited body of evidence on spinal osteomas and emphasizes the importance of a multidisciplinary approach for optimal patient outcomes.

Abstract
INTRODUCTION Although hydatid cyst remains one of the prevalent parasitic infections in humans, hydatid cyst of the thyroid is extremely rare, even in endemic areas. Here we present two cases of thyroid hydatid cysts. CASE PRESENTATION A 35 and a 50 year-old Iranian female with a positive history of animal contact were presented with a neck lump without any compressive symptoms. A physical exam revealed neck masses that elevated with swallowing. Thyroid gland ultrasonography showed cystic thyroid lesions, and fine needle aspiration (FNA) suggested a thyroid hydatic cyst. Thyroid lobectomy and isthmectomy were done for the first patient, and near-total thyroidectomy was done for the other. The pathology report confirmed the diagnosis of a hydatid cyst. None of the patients had hydatid cysts in other sites. Patients were discharged without an antiparasitic drug, and no recurrence was detected at the six-month follow-up. CONCLUSION It is necessary to consider hydatid cysts in the differential diagnosis of cystic lesions of the thyroid gland in endemic areas, especially in people with a positive history of animal contact.

Abstract
BACKGROUND Myelolipoma is a benign neoplasm of the adrenal cortex, composed of fat and hematopoietic cells. Although myelolipoma is benign, differentiation from adrenocortical cancer may be difficult. The presence of adrenal and extra-adrenal myelolipomas simultaneously is sporadic, making it a challenging case, especially when the preoperative diagnosis is ambiguous. CASE PRESENTATION A 65-year-old man was referred to our clinic due to a mass in the adrenal fossa. In the abdominopelvic computed tomography (CT), a well-circumscribed fat-containing 78 × 61 × 65 mm bi-lobulated mass was reported in the left adrenal fossa. The first differential diagnosis was myelolipoma. The patient was then referred to our clinic for a mass excision. He was asymptomatic and was scheduled to undergo laparoscopic-assisted adrenalectomy. After adrenalectomy and mass dissection, surprisingly, another mass was detected in the retroperitoneal area. The second mass was also dissected. The final diagnosis was myelolipoma for both masses. The patient has been symptom-free for nine months after the operation. CONCLUSION Simultaneous adrenal and extra-adrenal myelolipoma should be considered as one of the differential diagnoses. However, because this situation is extremely rare, the probability of malignancy should be highly regarded, and we suggest an obsessive approach when approaching this condition. It is essential to manage these cases on a case-by-case basis and tailor the management concerning intraoperative biopsy, the intraoperative appearance of tumors, and the location of extra-adrenal masses.

Abstract
Diabetic kidney disease (DKD), as a chronic diabetes-induced complication, is considered the most frequent leading cause of end-stage renal disease (ESRD). Regarding the observed protective effects of bilirubin, as a potential endogenous antioxidant/anti-inflammatory compound, against DKD progression, we planned to evaluate the effects of bilirubin administration on endoplasmic reticulum (ER) stress and inflammation in type 2 diabetic (T2D) rats fed high-fat diet (HFD). In this regard, thirty 8-week adult male Sprague Dawley rats were divided into five groups (n = 6). T2D and obesity were induced by streptozotocin (STZ) (35 mg/kg) and HFD (700 kcal/day), respectively. Bilirubin treatment was carried out for 6- and 14-week intervals (10 mg/kg/day), intraperitoneally. Then, the expression levels of ER stress-related genes (i.e. binding immunoglobulin protein (Bip), C/EBP homologous protein (Chop), and spliced x-box-binding protein 1 (sXbp1), as well as nuclear factor-κB (NF-κB) were analyzed using quantitative Real-time PCR experiments. Moreover, histopathological and stereological changes of kidney and its related structures were investigated for the studied rats. Bip, Chop, and NF-κB expression levels were significantly decreased under bilirubin treatment, while sXbp1 was up-regulated following the bilirubin administration. More interestingly, glomerular constructive damages seen in HFD-T2D rats, were considerably improved in the animals received bilirubin. Stereological assessments also revealed that bilirubin could desirably reverse the mitigation of kidney's total volume and its related structures, such as cortex, glomeruli, and convoluted tubules. Taken together, bilirubin has potential protective/ameliorative effects on DKD progression, especially through alleviating the renal ER stress and inflammatory responses in T2D rats with injured kidneys. In this era, clinical benefits of mild hyperbilirubinemia can be considered in human DKD.

Abstract
OBJECTIVE Osteoarthritis (OA) is a common and painful joint disease with multifactorial causes. Stem cells, due to their high ability to reproduce and differentiate, have created a new horizon in tissue engineering of cartilage and bone. Secretions are one of the new therapies that can be used with stem cells or separately. This study aimed to compare the healing effects of human dental pulp stem cells, cell-free secretome, and human dental pulp mesenchymal stem cells with secretome in the induced OA in male rats. METHODS Dental pulp mesenchymal stem cells were isolated and prepared from human dental pulp. The collagenase type II was injected into the knee of twenty-five male Sprague-Dawley rats, and after 10 weeks, OA was confirmed. Rats were divided into five groups (n = 5): 1) Human dental pulp stem cells plus secretome (HDP+Sec); 2) Human dental pulp stem cells (HDP); 3) Secretome (Sec); 4) Hyalgan as the positive control (Hya); 5) No treatment as the negative control (Ctrl). After 12 weeks since OA was confirmed, the healing process was examined by histopathology and radiology evaluations. RESULTS Histopathological evaluations, radiological assessments, and matrix indexes in three treatment groups significantly improved compared to the Ctrl and Hya groups. Surface in HDP+Sec was significantly better than the Ctrl group. In radiological evaluations, a significant decrease in OA was observed in the three treatment groups in comparison with the Ctrl groups. There was no significant difference between the treatment groups in any radiological and histopathological evaluations. HDP + Sec group slightly records better results compared to Sec or HDP treatment groups. CONCLUSION It was concluded that human dental pulp stem cells and their secretome promote cartilage regeneration due to their cell protective potential as well as matrix degeneration reduction capacity.

Abstract
Background Colorectal cancer (CRC) is a heterogeneous disease that complicates predicting patients' prognosis and their response to treatment. CRC prognosis is influenced by the tumor microenvironment (TME). The immune system is a critical component of the TME. Programmed cell death receptor 1 (PD-1) and T-cell immunoglobulin and mucin-domain containing-3 (Tim3) are inhibitory immune checkpoints that regulate immune response and may provide prognostic power. However, the effect of their expressions and co-expressions on the CRC prognosis remains unclear. Accordingly, this study aimed to investigate the prognostic value of the CD8, CD3, PD-1, Tim3 expression, and PD-1/Tim3 co-expression in patients with CRC. Materials and Methods One hundred and thirty six patients with CRC who underwent curative surgery were enrolled in the study. Immunohistochemical staining was performed for PD-1, Tim3, CD8, and CD3, and the expression of each marker was evaluated in the center of the tumor (CT), invasive margin (IM), and adjacent normal-like tissue. Result Our results indicated that high expression of PD-1 in IM was significantly associated with lower TNM stage, T-stage, M-stage, lack of metastasis, the presence of tertiary lymphoid structure (TLS), lack of recurrence (in the left-sided tumors), and larger tumor size (in right-sided tumors) (P<0.05). High expression of PD-1 in IM was also associated with improved overall survival (OS) in a subgroup of patients with high CD8 expression. High Tim3 expression in CT was associated with higher M-stage (M1) (in left-sided CRCs) (P<0.05). It was also associated with decreased OS in total cohort and left-sided CRCs and represented an independent prognostic factor for CRC patients in multivariate analysis. PD-1 and Tim3 co-expression had no synergistic effects on predicting OS. Conclusion Our findings suggest that the clinicopathological and prognostic significance of immune system-related markers such as CD8, PD-1, and Tim3 depends on the primary tumor sides. We also showed that Tim3 could act as a prognostic factor and therapeutic target in CRC. This marker is probably a more preferred target for immunotherapy than PD-1, especially in left-sided CRCs.

Abstract
BACKGROUND IL-18binding protein (IL-18BP) might play a role in tumor escape from immune surveillance through interacting with IL-37. Such interactions modulate the antitumor activity of IL-18 and affect regulatory T cell (Treg) function. However, the biological roles of IL-37 and IL-18BP have not yet been explored in brain tumors. This study aimed to investigate serum levels of IL-37 and IL-18BP in high-grade and low-grade brain tumors and determine their associations with pathological characteristics of the patients. SUBJECTS AND METHODS This case-control study consisted of 60 patients with brain tumors (40 low-grade and 20 high-grade) and 30 healthy controls. Enzyme-linked immunosorbent assay (ELISA) kits were used to measure the levels of IL-37 and IL-18BP in serum. RESULTS Our results indicated that serum levels of IL-37 and IL-18BP were significantly higher in patients with brain tumors (109.02, 426.37 pg/mL), high-grade (104.44, 428.87 pg/mL), and low-grade (113.88, 426.37 pg/mL) tumors in compared to healthy controls (35.03, 362.00 pg/mL), (P<0.05). Interestingly, our results revealed a significant positive correlation between IL-37 and IL-18BP serum levels in brain tumors (n=60, R=0.42, P=0.001). Our study also showed that serum levels of IL-37 and IL-18BP in glioblastoma grade IV were approximately similar to those in astrocytoma grade II, meningioma type I, and pituitary adenoma. Furthermore, no significant differences were found in serum levels of IL-37 and IL-18BP between patients with low-grade and high-grade tumors (P=0.24 and P=0.61, respectively). CONCLUSION The simultaneous increase in IL-37 and IL-18BP serum levels and their positive correlation may facilitate disease progression in low-grade and high-grade brain tumors by inhibiting antitumor immune responses.

Abstract
Nasal sebaceous carcinoma is an extremely rare cutaneous malignancy. We present the case of an 86-year-old female who had a skin nodule with surface telangiectasia on the right ala of the nose. The lesion had been removed and has been reconstructed with an advancement rotational flap with a minimal residual defect. Upon histopathological examination, the lesion was diagnosed with sebaceous carcinoma. The patient was followed up because of the high rate of recurrence as well as metastatic potential. No recurrence occurred during 4 years of follow-up, and the patient was unwilling to reconstruct the remaining alar defect. We present a rare skin cancer case that could be encountered during the head and neck examination by oral and maxillofacial surgeons. By reporting this case, we aimed to raise the awareness and familiarize clinicians with these less common lesions.

Abstract
Ewing sarcoma (ES) is a highly aggressive bone and soft tissue tumor that occurs
mainly in young children and adolescents and is associated with primary and
metastatic disease. Intramedullary ES (either primary or secondary) is rare, and
the ideal management remains inconclusive. We herein report intramedullary and
extramedullary metastatic ES in a single patient. A 46-year-old woman was
referred to our outpatient clinic from the oncology clinic with progressive
paraparesis and paresthesia for 1 week prior to presentation. She had developed
left clavicular ES 2 years earlier for which surgery and chemoradiotherapy had
been performed. At the present evaluation, she was diagnosed with intramedullary
thoracic and lumbar extradural masses. Thoracic surgery was performed, and a
biopsy of the lesion was obtained. The diagnosis of ES was confirmed
histopathologically, and she underwent adjuvant chemotherapy. Her neurological
status did not improve after surgery, and she underwent rehabilitation and
physical therapy. The lumbar lesion resolved with chemotherapy. Metastasis of ES
to the spinal cord, especially intramedullary lesions, is extremely rare, and
there is no standard management guideline. However, surgical decompression and
adjuvant chemotherapy are the main treatments in these cases.

Abstract
Background Previous studies have reported that gastrectomy and fundectomy can induce osteopenia. Body fat index is a new index of obesity that shows central obesity and other risks of obesity. Sleeve gastrectomy (SG) is a bariatric surgery and a new technique introduced as subsleeve, which only resected fundus of the stomach. In this study, it has been shown the effect of subsleeve and SG on fat index and bone densitometry in an animal model. Materials and Methods Rabbits were underlined SG, fundectomy (surgical removal of fundus), or sham-operated (controls without any resection), and after 12 weeks, fat index and bone densitometry were obtained. Results Our study showed that there was no significant difference between SG and fundectomy groups in bone mass density and fat mass after surgery in comparison with presurgery condition. SG group were associated with lower fat index and bone density, and it showed significantly decrease in weight after 1.5 months. Conclusion Sub-SG did not show any significant effect on fat index and bone densitometry in comparison with SG. However, we found lower fat index in sleeve group of rabbits, but it was not statistically significant.

Abstract
Brucellosis is considered as the most common bacterial zoonosis in the world. Although the laboratory findings are the most reliable diagnosis today, the current laboratory methods have many limitations. This research aimed to design and evaluate the performance of a novel technique based on the localized surface plasmon resonance (LSPR) to eliminate or reduce existing shortcomings. For this purpose, smooth lipopolysaccharides were extracted from Brucella melitensis and Brucella abortus and fixed on the surface of the gold nanoparticles through covalent interactions. After some optimizing processes, dynamic light scattering was used to characterize the probe. The detection of captured anti-Brucella antibody was performed by measuring the redshift on LSPR peak followed by the determination of cutoff value, which indicated a significant difference between controls and true positive patients (P value < 0.01). Furthermore, 40 sera from true negative samples and positive patients were used to evaluate the performance of this method by comparing its outcomes with the gold standard (culture), standard tube agglutination test, and anti-brucellosis IgM and IgG levels (ELISA). The sensitivity, specificity, positive predictive value, and negative predictive value showed an appropriate performance of the LSPR-based method (85%, 100%, 100%, and 86%, respectively). The current research results provide a promising fast, convenient, and inexpensive method for detecting the anti-Brucella antibodies in human sera, which can be widely used in medical laboratories to diagnose brucellosis quickly and effectively.

Abstract
Endometriosis, as the leading cause of infertility, is attributed to oxidative stress, inflammation, and autophagy dysregulation. This study was conducted to evaluate the effect of quercetin and metformin, alone or in combination, on the ectopic and eutopic endometrial tissues in a rat model of endometriosis. We divided 60 female rats into 6 groups, including SH, Endo, Endo + Oil, Endo + Q, Endo + M, and Endo + Q + M. The last five groups underwent a surgery, so that we could induce endometriosis, and after 4 weeks, daily treatment began, lasting for a month. Subsequently, the size and histoarchitecture of the endometrial implants, serum levels of 17β-estradiol, progesterone and tumor necrosis factor (TNF)-α, and markers of oxidative stress and autophagy were assessed utilizing ELISA and gene expression analysis. Our results shed light to the fact that serum TNF-α and 17β-estradiol levels significantly increased in endometriosis rats. Moreover, NADPH: quinone oxidoreductase (NQO1) enzyme activity and gene expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and autophagy markers significantly decreased; meanwhile, mammalian target of rapamycin (mTOR) gene expression increased in the ectopic endometrial tissues, as compared with eutopic ones. Surprisingly, our results demonstrated that the treatment in which we applied the combination of quercetin and metformin significantly reversed these changes and had a pronounced effect on the endometrial implant size and gene expression levels of mTOR and autophagy markers in ectopic endometrium. The findings of the present study suggest that quercetin, metformin, and their combination were of potential therapeutic effects on the rat model of endometriosis.

Abstract
Background Neoadjuvant chemotherapy (NACT) is the prime approach to the management of locally advanced breast cancer (LABC). Influenced by different factors such as pathologic tumor characteristics, hormone receptor status, HER2 and proliferation marker expressions, response to therapy cannot be easily predicted. Pathologic complete response (pCR) has been considered as an endpoint to NACT; however, pCR rates have been unsatisfactory in such patients. In this randomized trial, we studied the efficacy of carboplatin/gemcitabine as second-line NACT while evaluating the impact of different factors affecting response. Methods In this randomized controlled trial, 52 clinically non-responsive (confirmed by palpation and/or ultrasonography) LABC patients to 4 cycles of doxorubicin/cyclophosphamide followed by 4 cycles of paclitaxel ± trastuzumab were randomly allocated to two groups. “Control” group underwent breast surgery and were further evaluated for pCR (ypT0/is ypN0). “Intervention” group received 2 cycles of carboplatin/gemcitabine and patients were further evaluated for pCR following surgery. Results In a total of 52 patients, pCR rate was 30.7%. pCR and response rate in lymph nodes were higher in carboplatin/gemcitabine recipients (32% vs 29.7 and 44% vs 40.7% respectively), however differences were insignificant. In both the “intervention” group and total study population, most pCR cases were of the hormone receptor (HR)+/HER2+ subtype (87.5% and 75% respectively). HER2 positivity, ki67 expression, lower extent of ER positivity, higher tumor grade and tumor-infiltrating lymphocyte (TIL) lead to higher pCR rates. Adverse events following addition of carboplatin/gemcitabine were mostly hematologic and none required hospitalization. Anemia was the most common grade 3 adverse event observed. No grade 4 toxicity was evident. Conclusion Although the proposed carboplatin/gemcitabine combination could not improve pCR rates as expected, probability of immune activation following use of carboplatin in achieving response to NACT may be considered. Accounting for the highest number of pCR cases in the “intervention” group, the HR+/HER2+ subtype with high TILs may be considered as most responsive to the proposed regimen in this study. It is noteworthy that the proposed combination imposed minimal toxicity. Trial registration This trial was prospectively registered in IRCT.ir (IRCT2017100136491N1). Date of registration: 19 November 2017.

Abstract
Background Esophageal leiomyosarcoma (LMS) is a rare tumor that constitutes less than 1% of all malignant esophageal tumors. Concurrent occurrence of esophageal leiomyosarcoma with squamous cell carcinoma (SCC) is even rarer than isolated leiomyosarcoma. Case presentation In this report, we present a case of concurrent leiomyosarcoma and SCC in a 64-year-old woman presenting with vomiting and solid dysphagia, which has not been properly diagnosed following several referrals and diagnostic modalities. At last Exploratory laparotomy with gastric pull-up was performed in addition to radical laryngectomy with partial resection of the esophagus and subtotal thyroidectomy. Pathologic evaluation of the surgical specimen showed concurrent LMS (5.2 × 4.5 × 3 cm) and SCC (1.5 × 0.6 × 0.6 cm) at the same anatomical level in the proximal esophagus. Conclusions This study proposes the importance of using ancillary diagnostic tests such as immunohistochemistry (IHC) to diagnose less common cases such as concurrent LMS and SCC.

Abstract
BACKGROUND There is an ambiguous and controversial line between fetiform teratoma and fetus in fetu (FIF) as differential diagnoses of a fetiform mass. Classically, the presence of vertebral column often with a relatively proper arrangement of other organs around the central axis favor the diagnosis of FIF over teratoma. CASE Based on previously proposed criteria and the presence of vertebral organization in the radiological and histopathological assessment of the fetiform mass, we present an extremely rare case of adnexal FIF in a 10-year-old girl presenting with acute abdominal pain. SUMMARY AND CONCLUSION Whether FIF and fetiform teratoma are one entity or two, clinical discrimination for the choice of treatment seems to be unnecessary and the patient should be clinically followed for the probable malignant potential.

Abstract
BACKGROUND Uncomplicated infections such as candidiasis, bacterial vaginosis (BV), or trichomoniasis are easy to diagnose and treat. However, about 8% of patients will have a more complicated course with failure to respond to treatment or rapid recurrence of symptoms. There are many suggestions in Traditional Persian Medicine like myrtle (Myrtus communis L.) and oak gall (Quercus infectoria G.Olivier) for treatment of vaginitis. OBJECTIVES A clinical trial was designed to assess the efficacy of a novel herbal suppository, containing myrtle and oak gall (MOGS) in treatment of vaginitis. METHODS In a parallel randomized clinical trial, 120 women with vaginitis were randomly assigned to MOGS, metronidazole, or placebo. Formulation was simulated from traditional Persian manuscripts and MGOS was prepared after pharmaceutical optimization processing as well as quantification of gallic acid by HPLC. The study was double-blind for MOGS and placebo and single-blind for metronidazole group. RESULTS MOGS effectively improved vaginal discharge (p = 0.024 for BV and 0.018 for trichomoniasis) and pH (compared to placebo (p = 0.013) and metronidazole (p = 0.001)). Both MOGS and metronidazole could reverse whiff test. Metronidazole was the best medication for making Nugent score negative (p = 0.005) as well as the best therapy according to laboratory findings to treat BV in comparison with placebo (p = 0.021). While for trichomoniasis, MOGS could improve the disease more successfully (p = 0.001). Both MOGS and metronidazole treated mixed vaginitis (p = 0.002). CONCLUSION MOGS would be a chance for developing new treatment for trichomoniasis.

Abstract
BACKGROUND Even though several studies reported donor autologous nerve grafts for digital nerve defects, there is no report in the literature regarding acceptable graft for thumb nerves. The purpose of this study is to provide guidelines for autologous nerve graft selection by detecting similarities between thumb nerve zones and donor nerve with regard to the number of fascicles and cross-sectional area. MATERIALS AND METHODS Five cadavers were used in this study. An anatomical zoning system was defined for thumb nerves (zones 1, 2, 3). Sural nerve (SN), medial antebrachial cutaneous nerve (MABCN), lateral antebrachial cutaneous nerve (LABCN), posterior interosseous nerve (PIN), and anterior interosseous nerve (AIN) were selected as donor nerve grafts. The number of fascicles and surface area (mm2) was defined. RESULTS The mean of the fascicle number in zone 1, zone 2, zone 3, AIN, PIN, LABCN, MABCN, and SN were 3.8, 4.7, 6.1, 2.2, 1.8, 4.5, 3.1, and 6.4, respectively. The mean of the surface area in zone 1, zone 2, zone 3, AIN, PIN, LABCN, MABCN, and SN were 2.19, 6.26, 4.04, 1.58, 0.71, 5.00, 3.01, and 8.06, respectively. CONCLUSIONS LABCN is the best choice for all zones that has fascicular matching with all three zones of thumb nerves and caliber matching with zones 2 and 3. In zone 1, the best nerve graft is MABCN which has both suitable caliber and fascicle count.

Abstract
Introduction: Primary Diffuse Large B Cell Lymphoma of CNS (PCNSL) is a rare variant of Diffuse Large B Cell Lymphoma (DLBCL) and presents with an aggressive clinical course and usually resistant to commonly used therapy regimens. Recently, role of immune checkpoint molecules including PD-1 and PD-L1 confirmed in some solid tumors and lymphoma resulting tumor cells escape the immune system and help to survive and to spread. Inhibitors of PD-1 and PD-L1 have shown lasting responses in several solid and some hematological tumors, while limited studies evaluate checkpoint molecules on PCNSL. Method: In this study, we investigated PD-1 and PD-L1 expression by immunostaining on 71 patients with PCNSL and correlation with demographic data, location of the tumor, proliferation rate, cell of origin, and CD8 positive T cell infiltration in tumor microenvironment. Results: 16 from71 showed PD-1 expression, while PD-L1 expression were 42/71. No association was determined between PD-1/PD-L1 expression and gender, cell of origin, and proliferation rate, but a highly significant difference was determined between the infiltration of CD8 positive T cells in two groups of PD-1/PD-L1 positive and negative. Conclusion: This study revealed expression of check point molecules in remarkable number of PCNSL which may open new therapeutic recommendations in this aggressive lymphoma type.

Abstract
Ischemic stroke is one of the most frequent causes of injury in the central nervous system which may lead to multiorgan dysfunction, including in the lung. The aim of this study was to investigate whether brain ischemia/reperfusion with or without mechanical ventilation leads to lung injury. Male Sprague-Dawley rats were assigned to four groups: Sham, 1-h brain ischemia (MCAO)/24-h reperfusion (I/R), mechanical ventilation with moderate tidal volume (MTV), and I/R+MTV. The pulmonary capillary permeability (Kfc) was measured in the isolated perfused lung. Mean arterial blood pressure (MAP), heart rate (HR), blood-gas variables, histopathological parameters, lung glutathione peroxidase, and TNF-α were measured. Kfc in the I/R, MTV, and I/R+MTV groups were higher than that in the Sham group. In the I/R, MTV, and I/R+MTV groups, arterial partial pressures of oxygen and the arterial partial pressure of oxygen/fraction of inspired oxygen ratios were lower, whereas arterial partial pressures of carbon dioxide were higher than those in the Sham group. The histopathological score in the I/R group was more than that in the Sham group, and in the MTV and I/R+MTV groups were higher than those in the Sham and I/R groups. Furthermore, there were stepwise rises in TNF-α in the I/R, MTV, and I/R+MTV groups, respectively. There was no significant difference in MAP between groups. However, HR in the MTV group was higher than that in the Sham group. Brain ischemia/reperfusion leads to pulmonary capillary endothelial damage and the impairment of gas exchange in the alveolar-capillary barrier, which is exacerbated by mechanical ventilation with moderate tidal volume partially linked to inflammatory reactions.

Abstract
INTRODUCTION In cases of sacral nerve avulsion injuries, proximal nerve stumps are not available because of its protected position in pelvis, and results of nerve repair or graft are unsatisfactory. Nerve transfer can reduce the regeneration time and improve the results of recovery. HYPOTHESIS The obturator nerve transfer to the tibial nerve via saphenous nerve graft is possible and feasible. MATERIALS AND METHODS Ten male adult cadaveric lower limbs dissected to identify the location of the anterior branch of obturator nerve, the saphenous nerve and the medial gastrocnemius branch. The saphenous nerve was cut from its origin and transferred to the anterior branch of obturator nerve. As well, it was cut distally and transferred to the medial gastrocnemius branch. After nerve coaptation, surface area and fascicle count were determined by histological methods. RESULTS In all limbs, the proximal and distal stumps of saphenous nerve were reached the anterior branch of obturator and the medial gastrocnemius branch, respectively without tension. The mean of fascicle number in the anterior branch of obturator nerve, proximal and distal stump of the saphenous nerve and stump of medial gastrocnemius nerve branch were 2.90±0.99, 4.50±2.70, 4.00±2.26 and 4.30±1.25, respectively. DISCUSSION This study showed that it is possible to transfer the obturator nerve to the medial gastrocnemius branch via saphenous nerve bridge; and their histological parameters are match in a good manner. Therefore, this technique is suggested for patients with sacral nerve avulsion injuries. LEVEL OF EVIDENCE IV, case series of cadaveric study.

Abstract
BACKGROUND Liver disorders may be associated with normal pulmonary hemodynamic, hepatopulmonary syndrome (HPS), or portopulmonary hypertension (POPH). In this study, we aimed to investigate the effect of the severity of liver dysfunctions on blood-borne variables, and pulmonary hemodynamic during repeated ventilation with hyperoxic and hypoxic gases. METHODS Female Sprague Dawley rats were assigned into four groups of Sham (n = 7), portal vein ligation (PPVL, n = 7), common bile duct ligation (CBDL, n = 7), and combination of them (CBDL+ PPVL, n = 7). Twenty-eight days later, right ventricular systolic pressure (RVSP) and systemic blood pressure were recorded in anesthetized animals subjected to repeated maneuvers of hyperoxia (O2 50%) and hypoxia (O2 10%). Besides, we assessed blood parameters and liver histology. RESULTS Liver histology score, liver enzymes, WBC and plasma malondialdehyde in the CBDL+PPVL group were higher than those in the CBDL group. Also, the plasma platelet level in the CBDL+PPVL group was lower than those in the other groups. On the other hand, the serum estradiol in the CBDL group was higher than that in the CBDL+PPVL group. All the above parameters in the PPVL group were similar to those in the Sham group. During ventilation with hyperoxia gas, RVSP in the CBDL+PPVL group was higher than the ones in the other groups, and in the CBDL group, it was more than those in the PPVL and Sham groups. Hypoxic pulmonary vasoconstriction (HPV) was not detected in both CBDL+PPVL and CBDL groups, whereas, it retained in the PPVL group. CONCLUSION Severe liver damage increases RVSP in the CBDL+PPVL group linked to the high level of ROS, low levels of serum estradiol and platelets or a combination of them. Furthermore, the high RVSP at the noted group could present a reliable animal model for POPH in female rats.

Abstract
Abstract
Background
Neurofibromatosis type 1 (NF1) is a multisystem genetic disorder with autosomal dominant inheritance which predisposes the affected individuals to increased risk of developing certain benign and malignant central nervous system (CNS) tumors. NF1 patients are most notably prone to develop low-grade optic pathway, brainstem, and cerebellar astrocytoma. Current literature suggests that brain tumors in patients with NF1 tend to be less aggressive compared to sporadic ones. Glioblastoma multiforme (GBM) is a high-grade glioma which is relatively rare in patients with NF1 and is most commonly seen in supratentorial regions of the brain.
Case presentation
A 33-year-old patient was admitted in neurosurgery ward with acute hydrocephalus caused by a cerebellar mass lesion. On primary assessment, the patient was diagnosed with NF1. He was followed for 2 months and underwent surgical resection of the mass due to worsening symptoms. The pathology report revealed the malignant nature of the lesion. Patient received adjuvant chemo-radiotherapy with diagnosis of cerebellar GBM. Up to 19 months following surgery, he had gained a relatively well ability to walk and talk again.

Abstract
Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. Most patients present with steroid hormone excess or abdominal mass effect. Pure androgen-secreting ACCs are rare, while hypoglycemia is an unusual presentation of this malignancy. We present a 26-year-old woman with hypoglycemia and history of adrenalectomy due to a large adrenal mass which was diagnosed as nonfunctional adrenal adenoma. She was admitted in our hospital 10 days after her fetal loss with repeated episodes of severe hypoglycemia. She had a high serum dehydroepiandrosterone sulfate (DHEA-S) and her hypoglycemia was associated with low insulin and C-peptide levels. Imaging revealed liver metastasis and immunohistochemical studies of the biopsied lesions confirmed the diagnosis of ACC.

Abstract
Purpose Heterogeneity of breast cancer, the most common cancer in women, complicates approach to its treatment. Neoadjuvant chemotherapy (NAC) in the treatment of locally advanced breast cancer (LABC) with the endpoint of achieving pathologic complete response (pCR) is not always successful. The purpose of this study was to evaluate the clinicopathologic characteristics, biomarker status and response of LABCs to NAC. Patients and methods Core biopsies and post-surgical specimens of LABC patients were evaluated after receiving NAC. Their lymph node involvement, tumor staging, grading, size, tumoral and stromal lymphocytic infiltration (TLI, SLI), hormonal status, ki67, p53 and HER2 expression were evaluated. Response to NAC was assessed using pCR, Miller-Payne grading and residual cancer burden. Results In a total of 71 patients, pCR rate was 5.6%. Strong association was observed between ki67 positivity and p53 expression (P-value˂0.001). Also ki67, TLI and SLI showed association with triple negative tumor subtype (P-value 0.011, 0.002 and 0.014). Good response to NAC was associated with p53 expression. Nodal metastatic residue was also associated with primary tumor’s nuclear grade. Conclusion Strong correlation of ki67 and p53 can suggest probable interchangeability of both markers in the prognosis of LABC. In this study p53 even showed superiority to ki67 having association with good response. Strong association of ki67, TLI and SLI with triple negative tumor subtype can be parallel to an overall better response rate of this subtype. We can also propose the effectiveness of defining nuclear grade as a prognostic factor towards residual lymph node involvement post NAC.

Abstract
Background: Cutaneous leishmaniasis (CL) is the most form of leishmaniasis that caused by intracellular parasites, Leishmania. Case Report: A 39-year-old woman, known case of HIV infection, presented with a 6-month history of skin lesions initially on her face, then extending onto the chest, abdomen, and extremities. Laboratory examinations revealed leukopenia and a CD4 cell count of 280 cells / mm3. A biopsy was taken from skin lesions, and histopathological studies showed aggregates of macrophages filled with numerous Leishman bodies, the diagnosis of diffuse CL was confirmed. Consequently, she received liposomal amphotericin B (total dose of 40 mg/kg) as a case of diffuse CL. The skin lesions showed significant improvement after completion of treatment. Conclusion: Diffuse CL should be considered as a differential diagnosis in all patients with diffuse skin lesions mainly in the cases that suffer from disorders of cell-mediated immunity.

Abstract
BACKGROUND Fungal infection is a rare pathology in the sphenoid sinus, and extension into the pituitary fossa with visual loss has only been described in a few reports in the literature. Following publication of a recent report of pituitary abscess by Candida glabrata, we describe our own experience with a similar pathology. CASE DESCRIPTION In the present report, we overview a diabetic patient who sustained aspergilloma in his sphenoid sinus with extension to the pituitary fossa. Clinical presentations are discussed along with an emphasis on the role of endoscopic endonasal drainage of the abscess as the mainstay of treatment. Following administration of intravenous amphotericin B for 6 days, endoscopic drainage of the aspergillus abscess was done. Visual acuity improved immediately after the operation. At the 12-month follow-up visit, the improvement in visual acuity was maintained and magnetic resonance imaging showed no recurrence. CONCLUSION Correction of the underlying immune deficiencies, administration of intravenous antifungal agents perioperatively, endoscopic endonasal drainage of abscess, and a meticulous debridement of necrotic material, followed by a course of oral antifungal medication, comprises the standard treatment protocol for a fungus ball (aspergilloma) of the sphenoid sinus.

Abstract
Objective: This experimental work examined the healing effect and probable adverse impact of topical Prolavacid® solution (a polyhexamethylene biguanide-based wound cleanser) and topical Medihoney ointment in an animal model of cutaneous wound. Approach: We randomly divided 22 adult Sprague-Dawley rats (all were male) in two groups (n = 11): (1) those for which Prolavacid solution was poured on the skin wound surface; and (2) those animals for which Medihoney® ointment was applied to the wounds. These two agents were applied daily throughout the study period (21 days). We photographically followed the wounds' contraction with imaging performed on days 0, 7, and 21 postwounding. The histopathologic features of the healing wounds were evaluated using skin biopsies taken on days 7 and 21 postwounding. Results: The difference in mean wound surface area between two groups was not statistically significant on the examined days. Histopathological assessment indicated no statistically significant difference between the Prolavacid- and Medihoney-treated groups on days 7 and 21. We did not detect tissue necrosis following the topical application of Prolavacid solution. Innovation: This was the first study to examine the efficacy and probable adverse consequences of topical Prolavacid on cutaneous wound healing process. Conclusion: Our work showed no statistically significant difference between the efficacy of daily topical application of Prolavacid and Medihoney products on the healing process of fresh cutaneous wounds in our rat model.

Abstract
BACKGROUND Traffic accidents and traffic-related injuries and mortality have become a major public health concern in Iran. This study aimed to examine the role of drug and alcohol use in motor vehicle accidents in Iran. METHODS This case-crossover study was conducted on 441 drivers who survived a road traffic crash and were taken to the emergency department of Shahid Rajaee trauma hospital in Shiraz, southern Iran. Data were collected using checklists that included demographic characteristics and drug and alcohol use prior to driving. Alcohol and drug use was identified through self-report, and cannabis, morphine, and methamphetamine urine tests were used to confirm drug abuse among drivers. RESULTS In total 17.9% of drivers reported using drugs (cannabis, opium, or metamphetamine) and 8.84% of drivers reported consuming alcohol prior to the collision. The crude odds ratios (ORs) for having a crash for opium, cannabis, and metamphetamine were 1.94 (95% interval confidence [CI], 1.11-3.38), 2.37 (95% CI, 1.03-5.42), 5.5 (95% CI, 1.21-24.81), respectively, and for all drugs was 3.83 (95% CI, 2.28-6.43). The OR for alcohol was 3.5 (95% CI, 1.73-7.06) based on self-report. CONCLUSION Drug and alcohol use are increasing the risk of traffic crashes in Iran. Risk-reducing programs must be designed and implemented.

Abstract
Photothermal therapy (PTT) is a therapeutic method in which photon energy is transformed into heat rapidly via different operations to extirpate cancer. Nanoparticles, such as carbon nanotubes (CNTs) have exceptional optical absorbance in visible and near infrared spectra. Therefore, they could be a good converter to induce hyperthermia in PTT technique. In our study, for improving the dispersibility of multiwalled CNTs in water, the CNTs were oxidized (O-CNTs) and then polyethylene glycol (PEG) was used for wrapping the surface of nanotubes. The formation of a thin layer of PEG around the nanotubes was confirmed through Fourier transform infrared, thermogravimetric analysis, and field emission scanning electron microscopy techniques. Results of thermogravimetric analysis showed that the amount of PEG component in the O-CNT-PEG was approximately 80% (w/w). Cell cytotoxicity study showed that O-CNT was less cytotoxic than pristine multiwalled nanotubes, and O-CNT-PEG had the lowest toxicity against HeLa and HepG2 cell lines. The effect of O-CNT-PEG in reduction of melanoma tumor size after PTT was evaluated. Cancerous mice were exposed to a continuous-wave near infrared laser diode (λ=808 nm, P=2 W and I=8 W/cm2) for 10 minutes once in the period of the treatment. The average size of tumor in mice receiving O-CNT-PEG decreased sharply in comparison with those that received laser therapy alone. Results of animal studies indicate that O-CNT-PEG is a powerful candidate for eradicating solid tumors in PTT technique.

Abstract
Objectives: To determine the effect of bone marrow-derived mesenchymal stem cells (BMSCs) on regeneration of bone marrow and intestinal tissue and survival rate in experimental mice with acute radiation syndrome (ARS). Methods: Forty mice were randomly divided into two equal groups of A receiving no BMSC transplantation and B receiving BMSCs. BMSCs were isolated from the bone marrow and cultured in DMEM media. Both groups were irradiated with 10 Gy (dose rate 0.28 Gy/ min) 60CO during 35 minutes with a field size of 35×35 for all the body area. Twenty-four hours after γ irradiation, 150×103 cells of passage 5 in 150 µl medium were injected intravenously into the tail. Animals were euthanized one and two weeks after cell transplantation. They were evaluated histologically for any changes in bone marrow and intestinal tissues. The survival rate in mice were also determined. Results: A significant increase for bone marrow cell count and survival rate were observed in group B in comparison to group A. Histological findings denoted to a healing in sample tissues. Conclusion: BMSCs could significantly reduce the side effects of ARS and increase the survival rate and healing in injured tissue. As such their transplantation may open a window in treatment of patients with ARS.

Abstract
BACKGROUND Hemostatic agents can play a key role in controlling severe hemorrhage after trauma. Previously, some criteria have been defined for improving the quality of these products; one of them is that the hemostat causes no further tissue injury. CoolClot is a recently introduced hemostatic agent that its effects on wound healing have not yet been examined, which this study aims to address. MATERIALS AND METHODS Thirty-four adult male Sprague-Dawley rats were assigned randomly to two groups (n = 17): a study group where CoolClot hemostatic agent was applied on their wounds, and a control group whose wounds were washed only with sterile saline. The rats underwent dorsal full-thickness skin excisional wounds (20 mm diameter). On day 12 after wounding, seven rats were chosen in a random manner from each of the groups of study and control, and their skin biopsies from the wound sites were sent for histologic examination. Skin samples of the remaining rats in each group were taken on the 21st d after wound creation. Wound healing was also monitored photographically. In addition, wound surface temperature after wounding, and the application of CoolClot was recorded. RESULTS There was no significant difference between the groups of study and control regarding the examined histopathologic parameters. The maximum increase in wound surface temperature was 1.56°C. CONCLUSIONS One-time topical usage of CoolClot has no significant negative effect on the wound healing process. In addition, no significant increase in wound surface temperature will occur after the application of this agent.

Abstract
Background: The prevalence rate of gastric infections caused by Helicobacter pylori is different in between as well as within various countries, including Iran. Objectives: This study was aimed to evaluate the prevalence of H. pylori in Iranian adult patients with dyspepsia. Patients and Methods: A total of 548 patients with dyspepsia referred to Namazi Hospital, a referral center for gastrointestinal diseases in Shiraz, south of Iran, were evaluated in a cross-sectional study. The diagnosis of dyspepsia was based on clinical findings. Upper gastrointestinal endoscopy was performed for all the patients and two antral biopsies were taken from all the included ones. The patients were categorized based on the endoscopic findings, to four groups: Two positive test results (Gram staining, rapid urease test, and culture) was considered as a positive-definite H. pylori infection for each patient. Results: From the 548 included patients (238 males and 310 females), H. pylori was detected in 170 (31.2%). The mean age was 40.38 ± 15.39 years old. H. pylori infection was detected in 26.1% of male and 34.8% of female patients and its prevalence increased with age. Eighty three (48.8%) patients were positive for H. pylori infection, of which, 12.4% had normal and 36.4% had abnormal nonulcerative endoscopic findings; 17.1% of patients were ulcerative and 34.1% had ulcer with or without concurrent abnormality. Conclusions: Findings from this study showed a lower prevalence of H. pylori infection than other studies and its prevalence increased with age. There was no association between sex and infection. The most common endoscopic abnormality in H. pylori-positive patients was ulcerative lesion.

Abstract
A solitary skull metastasis from hepatocellular carcinoma is rare. A 38-year-old man with hepatocellular carcinoma presented to our institution with a palpable temporal scalp mass. We took a magnetic resonance image, and discovered an enhanced and osteolytic skull tumor. The tumor was removed by an occipital craniectomy, and the histologic diagnosis was a cranial metastasis owing to hepatocellular carcinoma. A skull metastasis owing to hepatocellular carcinoma should be considered in the differential diagnosis in patients with a subcutaneous scalp mass. Although a distant metastasis can affect the prognosis of the patient, early treatment may improve survival.

Abstract
Neurobrucellosis is a rare neurological complication of brucellosis. This report describes 19 patients of neurobrucellosis and they accounted for 8% of all cases of brucellosis admitted to Shiraz University Hospitals over a period of eight years. Headache, fever, fatigue, drowsiness and neck stiffness were the common clinical features. Cerebrospinal fluid (CSF) showed pleocytosis in 100%, elevated protein levels in 89% and low glucose level in 47% of the patients. All the patients improved with specific antibiotic treatment. Of the 19 patients, 10 (52.5%) patients received treatment for 8 to 28 weeks. Duration of antibiotic treatment was: 8-14 weeks in 8 (42%) patients; 24-28 weeks in 2 (10.5%) patients; 6 months in 7 (37%) patients; 12 months in 1 (5.3%) patient; and 18 months in 1 (5.3%) patient. Clinicians in endemic areas should consider the likelihood of neurobrucellosis in patients with unexplained neurological and psychiatric symptoms.
