Percutaneous management in hepatic alveolar echinococcosis: A sum of single center experiences and a brief overview of the literature

BACKGROUND Hepatic alveolar echinococcosis(HAE) is a serious zoonotic infection that affects humans. It may have a tumor-like appearance at times. Percutaneous treatment of HAE patients is extremely relaxing for them. HAE is a significant human zoonotic infection caused by the fox tapeworm Echinococcus Multilocularis larvae. It possesses the characteristics of an invasive tumor-like lesion due to its infiltrative growth pattern and protracted incubation period. The disease is endemic over centra...     

Use of cytarabine and idarubicin in a newly diagnosed AML patient with a severe wound

Acute myeloid leukemia (AML) is malignant tumor of haemopoietic precursor cells of non-lymphoid lineage. AML can atypically present with non-spesific cutaneous lesions or wounds. There are rare acute leukemia cases which present with genital ulcerations or pyoderma gangrenosum in the literature. The effect of acute leukemia on wound healing is not known, but it is thought that cytopenias and chemotherapy can impair wound healing in patients with leukemia. The effects of chemotherapeutic agents on wound healing are arguable. Here we present wound care strategies and simultaneously applied chemotherapy in an AML patient.     

Expression of proliferative and preapoptotic molecules in human myometrium and leiomyoma throughout the menstrual cycle

The pathogenesis of leiomyoma may be related to an imbalance in the interaction of sex steroids with paracrine growth factors that may control the modulation of mitogenesis and local immunity. The authors investigate the temporal and spatial expression of proliferative and preapoptotic molecules that may participate in the modulation of myometrial function and leiomyoma pathogenesis. Immunohistochemistry and Western blot analysis are used to investigate Fas ligand (FasL), phosphatase and tensin homolog deletion on chromosome 10 (PTEN), and proliferating cell nuclear antigen (PCNA) expression in myometrium and leiomyoma. Western blot results show that in the secretory phase, FasL expression is 1.8-fold and 2.3-fold higher compared with the proliferative phase in the myometrium and leiomyoma, respectively (P = .022 and .047, respectively). A paired comparison between myometrium and leiomyoma reveals higher FasL expression in the leiomyoma (P = .003). On the contrary, when compared with the secretory phase, PCNA expression during the proliferative phase is 4.6-fold and 3.7-fold higher in the myometrium and leiomyoma, respectively (P = .041 and .034, respectively). A paired comparison between myometrium and leiomyoma reveals higher PCNA expression in the leiomyoma. Furthermore, lower PTEN expression is detected in the leiomyoma compared with the myometrium (P < .032). Immunohistochemistry results reveal that FasL, PTEN, and PCNA are expressed in the myometrium and leiomyoma, consistent with the results from the Western blot analysis. The results suggest that FasL, PTEN, and PCNA may be involved in the pathophysiology of leiomyoma. A higher FasL level in the leiomyoma is likely to correspond to suppression of local immunity by inducing apoptosis of immune cells, while a higher level of PCNA and a lower level of PTEN may be related to increased mitogenesis and decreased apoptosis in leiomyoma.     

Shall We Inject Superficial or Deep to the Plantar Fascia? An Ultrasound Study of the Treatment of Chronic Plantar Fasciitis

We compared the effectiveness of ultrasound (US)-guided corticosteroid, injected superficial or deep to the fascia, in patients with plantar fasciitis. Thirty patients (24 females [75%] and 6 males [25%]) with unilateral chronic plantar fasciitis were divided into 2 groups according to the corticosteroid injection site: superficial (n = 15) or deep (n = 15) to the plantar fascia. Patient heel pain was measured using a Likert pain scale and the Foot Ankle Outcome Scale (FAOS) for foot disability, evaluated at baseline and repeated in the first and sixth weeks. The plantar fascia and heel pad thicknesses were assessed on US scans at baseline and the sixth week. The groups were similar in age, gender, and body mass index (p > .05 for all). Compared with the baseline values, the Likert pain scale (p < .001 for all) and FAOS subscale (p < .01 for all) scores had improved at the first and sixth week follow-up visits in both groups. Although the plantar fascia thickness had decreased significantly in both groups at the sixth week (p < .001 for both), the heel pad thickness remained unchanged (p > .05 for both). The difference in the FAOS subscales (pain, p = .002; activities of daily living, p = .003; sports/recreational activities, p = .008; quality of life, p = .009) and plantar fascia thickness (p = .049) showed better improvement in the deep than in the superficial injection group. US-guided corticosteroid injections are safe and effective in the short-term therapeutic outcome of chronic plantar fasciitis. Additionally, injection of corticosteroid deep to the fascia might result in greater reduction in plantar fascia thickness, pain, and disability and improved foot-related quality of life.     

End-to-end microvascular anastomosis in the rat carotid artery using continuous horizontal mattress sutures

This paper reports a continuous horizontal mattress suture technique with advantages such as decreased time for anastomosis, minimized anastomotic leakage, eversion around the vessel edges, and other advantages which the continuous anastomosis technique has. This technique was compared with the classical interrupted and classical continuous suture techniques on a total of 59 Sprague-Dawley rat common carotid arteries: Group 1 (n = 19), interrupted suture technique; Group 2 (n = 20), standard continuous technique, and Group 3 (n = 20), continuous horizontal mattress technique. Early (30 min) and late (21 days) patency rates, anastomosis time, leakage on clamp release, oozing duration, additional sutures needed, and total number of sutures placed were statistically compared between groups. Specimens were taken at the 21st day randomly, and light microscopy (LM), scanning electron microscopy (SEM), and angiographic studies were performed. Results revealed that the continuous mattress suture technique has the advantages of providing a water-tight anastomosis with less suture materials in a shorter time, and minimal intraluminal suture material which can incite thrombosis. On the other hand, a tendency to anastomotic stricture was found to be the sole disadvantage of this technique.     

Beneficial effect of hyperbaric oxygenation on liver regeneration in cirrhosis

BACKGROUND: Underlying hepatic injury and cirrhosis are leading factors that interfere with the post-operative liver regeneration and function. Hyperbaric oxygenation (HBO) has been reported to ameliorate the ischemia-reperfusion injury of the liver, to induce compensatory hypertrophy of the predicted remnant liver in rats after portal vein ligation and to augment liver regeneration after hepatectomy in non-cirrhotic rats. Our aim was to determine the effect of HBO treatment on liver regeneration after partial hepatectomy in normal and cirrhotic mice in this experimental study. MATERIALS AND METHODS: The effect of HBO on liver regeneration was studied in a mice model combining carbon tetrachloride induced cirrhosis and partial hepatectomy. Mice were divided into four groups: Control, cirrhotic, non-cirrhotic HBO-treated, and cirrhotic HBO-treated. All animals underwent 40% hepatectomy. Liver regeneration was evaluated by the proliferating cell nuclear antigen-labeling index. Serum aspartate aminotransferase and alanine aminotransferase levels were measured to evaluate liver injury. RESULTS: Serum alanine aminotransferase and aspartate aminotransferase levels were significantly decreased in HBO-treated cirrhotic group compared to cirrhosis group after hepatectomy (P = 0.001 and P = 0.014, respectively). The proliferating cell nuclear antigen labeling index was significantly higher in HBO treated cirrhotic group than in cirrhotic group after hepatectomy (P = 0.022). CONCLUSIONS: Our results suggest that HBO treatment improves liver functions and augments hepatocyte regeneration in cirrhotic mice after hepatectomy. Post-operative HBO treatment may have a beneficial effect on post-operative liver function and regeneration in cirrhotic patients.
