RESUMEN
Intramuscular hemangiomas are uncommon benign endotheliomas that typically occur in the trunk and limbs. Head and neck involvement is relatively infrequent, with the masseter muscle being the most commonly affected site. We present a rare case of intramuscular hemangiomas arising from the semispinalis muscle. A 31-year-old male presented with a painless swelling in the left upper neck region, gradually increasing in size over the past year. Imaging studies revealed a well-defined mass originating from the semispinalis muscle. Surgical excision was performed successfully, and histological examination confirmed the diagnosis of a mixed intramuscular hemangioma. The patient remained recurrence-free during the 2-year follow-up period. Intramuscular hemangiomas in the posterior neck muscles are rare, with only a few reported cases. Wide surgical resection with control of feeding vessels is the optimal treatment, and follow-up is recommended to monitor for local recurrence. This case report highlights the clinical presentation, diagnostic challenges, and successful surgical management of intramuscular hemangiomas in a unique location, emphasizing the importance of accurate diagnosis and appropriate treatment of this rare tumor.
RESUMEN
Trichofolliculoma (TF) is a rare benign adnexal follicular tumor, described as hamartoma with follicular differentiation according to some authors. It typically appears during adulthood on the face or scalp as an isolated nodule with protrusion of central tufted hairs. We present a retrospective series of eleven patients with histologically confirmed TF to evaluate epidemiological, clinical, and histopathologic characteristics. The mean age at excision was 46 years with extremes ranging from 20 to 75 years. The sex ratio M/F was 0.37. Clinical presentation was a papule or nodule with an average diameter of 6,7mm (2-15 mm), firm with central pit in 54 percent and visible emerging vellus hairs in 18 percent of cases only. The localization was on the face in seven cases (63.6%) and only four cases were located outside the face (scalp [n=2], sub mammary fold [n=1] and shoulder [n=1]). Histologically, a cystically dilated hair follicle containing keratinous material with several mature and immature branched follicular structures is described in all cases. According to our series, TF occurs predominantly in women without age predilection, in the face. Central tufted hairs are only found in a minority of cases corresponding histologically to many secondary vellus hair follicles. In fact, histopathological examination is the gold standard for the diagnosis because clinical diagnosis could be challenging. Histology and dermoscopy may vary according to the age of the lesion. To date, only few case series have been published.
RESUMEN
While gastric cancer often metastasizes to the liver, lymph nodes, and lungs, skeletal muscle metastasis is a rare event. The most common primary tumor metastasizing to the extraocular structures is breast cancer. Gastric carcinoma metastatic to the extraocular muscles is a rare event announcing a spreading disease with a bad prognosis. Here, we report a case of an asymptomatic gastric carcinoma metastasizing to the superior oblique muscle diagnosed via an endoscopic endonasal biopsy.
RESUMEN
Hemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening hyperinflammatory condition that may be triggered by infections, autoimmune and immunologic disorders, malignancies, and metabolic diseases. Early and accurate diagnosis of HLH and its underlying cause is of paramount importance for proper management and prognosis. We report the case of a Tunisian 21-month-old girl who initially presented clinical features of HLH related to a lysosomal acid lipase deficiency. The genetic sequence analysis of the LIPA gene revealed a never described homozygous mutation c.966G>C (p.Gln322His). The parents were heterozygous for this mutation. Enzyme replacement therapy was not provided for the patient. She received etoposide, corticosteroids, and cyclosporine for the HLH. She is waiting for hematopoietic stem cell transplantation. To the best of our knowledge, this is the second Tunisian case of secondary HLH complicating lysosomal acid lipase deficiency related to a new homozygous mutation: c.966G>C (p.Gln322His).

The hyperlipidemia is a serious health problem that increases the risk of many complications including cardiovascular disease. This study aims to evaluate the possible antihyperlipidemic effects of the feather protein hydrolysate (FPH) in a mice fed with a high-fat diet (HFD)-fed mice during 5 weeks. The FPH administration improved dose-dependent lipid profile, as well as the liver and renal dysfunction indices in hyperlipidemic mice. The FPH also restored the antioxidant status in liver, kidney, and heart by lowering the lipid peroxidation and enhancing the antioxidant enzymes (catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase [SOD]). Moreover, the histological studies proved that FPH administration prevents hepatic steatosis, glomerular hyperfiltration risk, and cardiac muscle hypertrophy. Accordingly, the FPH is a promising novel medicinal ingredient for possible use in the hyperlipidemic treatment and related complications.
RESUMEN
This study aims to examine the effects of non-hydrolyzed octopus (Octopus vulgaris) muscle proteins (NHOPs) and their hydrolysates (OPHs) on alloxan induced diabetes in Wistar rats (AIDR). Animals were allocated into seven groups of six rats each: control group (C), diabetic group (D) and diabetic rats treated with acarbose (Dâ¯+â¯Acar), non-hydrolyzed octopus proteins (Dâ¯+â¯NHOPs) and octopus proteins hydrolysates (Dâ¯+â¯OPHs) groups. The diabetic rats presented a significant increase in glycemic status such as α-amylase activity (in plasma, pancreas and intestine), hepatic glycogen, blood glucose and glycated hemoglobin (HbA1c) levels, as well as a significant decrease in the levels of plasma insulin and total hemoglobin compared to control group. In addition, plasma and liver contents in total cholesterol, triglycerides and LDL-cholesterol significantly increased in AIDR compared to control group. However, the daily administration of OPHs for 30â¯days improved the glucose tolerance test, the glycemic status of diabetic rats and corrected the lipid profiles. Further, a significant increase in the activities of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and gamma-glutamyl transpeptidase as well as in the level of plasma bilirubin on diabetic status was observed, indicating considerable hepatocellular injury. OPHs treatment was found to attenuate the increased activities of the plasma enzymes produced by diabetes and caused a subsequent recovery towards normalization compared to the control group. By contrast, the NHOPs treatment was found to increase the glucose metabolic disorders in AIDR. These beneficial effects of OPHs were confirmed by histological findings in the hepatic and pancreatic tissues of diabetic treated rats. Indeed, they avoid lipid accumulation in the hepatocytes and protect the pancreatic ß-cells from degeneration. Our results thus suggest that OPHs may be helpful in the preventing from diabetic complications by reversing hepatotoxicity.

PURPOSE: To investigate whether the oxidative stress is involved in the evolution of Graves' disease (GD) and Hashimoto thyroiditis (HT) into Papillary Thyroid Carcinoma (PTC), 8-hydroxy-2'-deoxyguanosine (8-OHdG) and cancer related proteins (Bcl-2, p53 and Ki-67) expressions were evaluated in these pathologies. PATIENTS AND METHODS: Immunohistochemical method was applied on 25 thyroid tissues. Allred score (AS) serving to evaluate the immunostaining is based on a scale from 0 to 8. "Negligible expression" was assigned to a score of 0 to 2, "expression" and "overexpression" were attributed to a score of 3-5 and ≥6 respectively. RESULTS: PTC cancer cells exhibited 100% 8-OHdG "overexpression" compared to 87.5% in PTC non-malignant epithelial (NME) ones (p<0.05). Higher 8-OHdG AS was found in PTC NME cells compared to GD and HT (p<0.001, p<0.05 respectively). "Overexpression" of Bcl-2 was noted in all PTC cell types. Remarkably, just like the PTC cancer and NME cells 33.3% of HT and 50% of GD patients' revealed simultaneous "overexpression" of Bcl-2 and 8-OHdG in epithelial cells. No staining was detected for p53 in all pathologies. PTC lymphoid cells exhibited 100% "overexpression" for 8-OHdG and Bcl-2 with concomitant "negligible expression" for Ki-67 in 87.5% of patients. In contrast, HT lymphoid cells showed 22.2% "expression" and GD 62.5% "expression" and 12.5% "overexpression" of Ki-67. CONCLUSIONS: Simultaneous "overexpression" of 8-OHdG and Bcl-2 in GD and HT could be considered as prognostic markers while "negligible expression" of Ki-67 in PTC lymphoid cells suggests an anergic state favoring the tumor escapes from the immune system.

The purpose of this study was to prevent or to delay the onset of diabetes-related complications, by using a natural marine resource, Sardina pilchardus oil, administrated to alloxan-induced diabetic rats showing hyperglycemia and hyperlipidemia. Gas chromatography-mass spectrometry analysis of the sardine oil detected 18 constituents. The major ones were n-3 highly unsaturated fatty acids among which are docosahexaenoic acid (25.09%) and eicosapentaenoic acid (19.61%). Sardine oil inhibited the α-amylase activity in rats' sera (26.82%) and thus improved glycemia (54%). The supplement of this oil protected the ß-cells from death and damage, significantly decreased total triglycerides, total cholesterol and LDL-cholesterol concentrations in diabetic rats' sera and increased the HDL-cholesterol level. Gavage administration of this oil to rats protected the liver and kidney functions by reducing the aspartate transaminase, alanine transaminase and phosphatase alkaline activities, and by decreasing creatinine, urea and uric acid levels.

This study aims to explore the hypocholesterolemic effects and antioxidative activities of zebra blenny protein hydrolysates (ZBPHs) in rats fed with a hypercholesterolemic diet. The rats were fed during eight weeks a standard laboratory diet (normal rats), a high-cholesterol diet (HCD) (1%) or a HCD and orally treated with ZBPHs or undigested zebra blenny proteins (UZBPs) (400 mg per kg per day). Results showed that a hypercholesterolemic diet induced the increase of total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C). Treatment with ZBPHs increased the level of high-density lipoprotein cholesterol (HDL-C) and decreased significantly the levels of TC, TG, and LDL-C. In addition, ZBPH treatment showed significant normalization of thiobarbituric acid-reactive substance (TBARS) levels as well as catalase, superoxide dismutase (SOD), and glutathione peroxidase (GPx) activities in renal and hepatic tissues. Furthermore, ZBPHs may also exert significant protective effects on liver and kidney functions, evidenced by a marked decrease in the level of serum urea, uric acid, creatinine, alkaline phosphatase (ALP), and alanine aminotransferase (ALAT). Histological studies confirmed that ZBPHs effectively protected the livers and kidneys against hypercholesterolemia-mediated oxidative damage. Therefore, the study strengthens the hypothesis that ZBPHs can be used as novel antioxidants and hypocholesterolemic compounds against hyperlipidemia induced atherosclerosis.

The cytomegalovirus (CMV) is the most common maternal-fetal transmission infectious disease. The diagnosis of this infection is rarely made on antenatal sonographic signs. Pathological examination could, in this case, make etiologic diagnosis. We report the case of a terminated pregnancy, at the term of 19 weeks of gestation, occurring in a 31-year-old woman. The sonography found a terminated pregnancy with anamnios. Histological examination of samples of fetal internal organs showed intranuclear inclusions, compatible with CMV infection. The main objective of our work is to emphasize the value of histological examination in the diagnosis of fetal death etiology. Moreover, we will discuss the benefit of antenatal screening of CMV maternal infection.

The present study investigates the hypoglycemic and hypolipidemic effects of protein hydrolysates obtained from zebra blenny (Salaria basilisca) muscles treated with three different crude alkaline protease extracts in alloxan-induced diabetic rats (AIDR). Analysis of amino acid composition revealed that zebra blenny protein hydrolysates (ZBPHs) were valuable sources of essential amino acids and rich in leucine, which is one of the active ingredients for blood glucose control by inducing insulin release in both rats and humans. Treatment of AIDR with ZBPHs revealed a significant inhibition of α-amylase activity in serum and the intestine, as well as a reduction of blood glucose and glycated hemoglobin (HbA1c) levels in diabetic rats. Further, ZBPHs also decreased significantly the triglyceride (TG), total-cholesterol (TC) and LDL-cholesterol (LDL-c) levels in the serum and liver of diabetic rats, while they increased the HDL-cholesterol (HDL-c) level, which helped to maintain the homeostasis of blood lipids. Furthermore, ZBPHs exhibited potent protective effects against heart attack markers by reversing myocardial enzyme serum back to normal levels. ZBPHs may also exert significant protective effects on liver function, evidenced by a marked decrease in the level of serum bilirubin as well as in the activities of alanine aminotransferase (ALT), alkaline phosphatase (ALP), and gamma-glutamyl transpeptidase (GGT). These beneficial effects of ZBPHs were confirmed by histological findings in the hepatic and pancreatic tissues of diabetic rats. Indeed, they avoid lipid accumulation in the hepatocytes and protect the pancreatic ß-cells from degeneration. Overall, the findings of the current study indicate that ZBPHs significantly attenuated hyperglycemia and hyperlipidemia in AIDR.
