ABSTRACT : A total of 150 buffalo’s ocular muscle samples were examined for the presence of sarcosporidians in Assiut Governorate. These samples included 80 males less than 2 years old and 70 females more than 5 years old. Sarcocystis spp. were detected in 55 (36.66%) of examined animals. The incidence of infection in males was 15.0% and in females was 61.42%. Two species of Sarcocystis were detected in the present work: S.fusiformis was detected in 9.33% of examined animals, where in males it was 1.25% and in females was 18.57%. S.levinei was detected in 34.66% of examined animals, in males it was 15.0% and in females was 57.14%. Mixed infection with the two species was detected in 11 (7.33%) of examined animals. The morphological characters and the ultrastructure of each species were described.The present data showed that ocular muscles are a preferreble site for Sarcocystis especially S.levinei. It is ,therefor recommended that Sarcocystis cysts showed be looked for in ocular muscles of humans complaining of ocular muscle disease.

Vitamin D deficiency has been recognized as a worldwide epidemic, affecting even healthy population. The awareness and practices of primary health care physicians regarding vitamin D needs to be highlighted, as improving the knowledge of physicians will improve the knowledge of the public as a whole. This study aimed to address the knowledge, attitude and practice of primary health care physicians regarding vitamin D in Riyadh city, KSA. A cross-sectional study was conducted using a self-administered questionnaire among primary care physicians; currently working in Riyadh city, KSA. Descriptive statistics: mean, standard deviation, frequencies, percentage were calculated. Of the 158 eligible participants, there were 43.7% male. The mean participant's age of was 40.7 ± 9.6 years. Of all the participants; 51.3% showed good knowledge regarding vitamin D, while 48.7% showed poor knowledge; 55.1% had positive attitude. Participants were asked about patient features that would alert them to vitamin D status. Fatigue was shown to alert more male than female physicians participants (75.4% vs. 58.4%, p = 0.026). Participants were asked about ways of managing vitamin D deficiency. Nutrition advice was mostly given by older physicians (p = 0.044) and non-Saudis (p = 0.003). In conclusion, this survey identified a gap in knowledge and practice among Primary Health Care physicians. The confusion could be partly attributed to different guidelines and sources of information. This study showed that continuous medical education and online sources were the most common sources of information about vitamin D among physicians.

Delayed recovery from anesthesia remains a very challenging subject for anesthesiologists. This case report describes the clinical course of delayed recovery from neuromuscular blockade after laparoscopic partial nephrectomy in a patient on simvastatin. The patient was hypertensive on regular treatment with oral captopril 25 mg twice daily and amlodipine 5 mg once daily and hypercholesterolemic on regular simvastatin 40 mg once daily with a normal electrocardiogram (ECG). All preoperative laboratory findings were within normal ranges. The patient was premedicated with midazolam 1 mg and general anesthesia was induced with fentanyl 2 μg/kg body weight, propofol 2 mg/kg and rocuronium bromide 0.6 mg/kg to facilitate tracheal intubation. Anesthesia was maintained with inhalation of isoflurane 1.0–1.5 % in 40 % oxygen-enriched air and 25 μg boluses of fentanyl. The patient did not require any additional rocuronium throughout surgery which was finished after 4 h. The patient most probably had preoperative simvastatin-inducedmyotoxicity. This potentiated the muscle relaxant effect of rocuronium bromide and was the reason for patient unresponsiveness and delayed postoperative recovery. We can conclude that anesthesiologists should preoperatively identify statin myotoxicity and to avoid neuromuscular blocking drugs for statin-treated patients. Also, preoperative adjustment of statin dosage may be recommended.

Background: Hepatocellular carcinoma (HCC) is the most common type of liver malignancies. Yet, the outcome of the traditional chemotherapeutic agents in the management of HCC still unsatisfactory, most probably due to their limited therapeutic efficacies. Thus, there is an urgent medical need for alternative therapeutic approaches for fighting HCC. Aim: our study aimed at evaluating the possible synergistic antitumor activity of the herbal alkaloid berberine (BER) with the conventional doxorubicin (DOX) in a DENA-induced HCC rat model. Methods: HCC was induced in male Wistar rats by oral DENA administration in their drinking water (100 mg/L) for 8 weeks. In addition to a positive and negative control groups, a group of animals (10 rats) was given DOX (4× 2.5 mg/kg, i.v., weekly). Another group (10 rats) was given BER (100 mg/kg) by oral gavages daily for one month. A third group (10 rats) was given a combination of both BER and DOX in the above described dose and schedule. Results: Combination between DOX and BER was superior over their corresponding individual administrations as indicated by significant improvement in the overall estimated indices of liver function. Also, in comparison to individual therapy, this combination was obviously more potent to reduce the levels of novel HCC related tumor markers including serum AFP-L3 and tissue levels of Golgi protein 73, and glypican 3. Furthermore, histological investigations and assessments of hepatic tissue levels of some oxidative stress markers strongly confirmed the advantageous effects of combined BER and DOX in fighting DENA-induced HCC. Conclusion: our study conclusively revealed that combining BER with DOX exhibited a promising preclinical anticancer efficacy and could be considered as a novel strategy to synergistically combat HCC in clinical practices.

Abstract Background Patient position after spinal anesthesia has had variable effects on blood pressure and ephedrine requirements. The aim of this study was to determine the effects that sitting the patient up for five minutes after spinal anesthesia would have on intraoperative fluid and ephedrine requirements. Methods The study included 120 women at term gesta- tion who were scheduled for Cesarean delivery under spinal anesthesia. After anesthetic administration, the women were randomized either to sit up for five minutes then lie down (Group S) or to lie down immediately (Group L) to a tilted supine position. A blinded observer recorded sensory block level, systolic blood pressure, heart rate, ephedrine and fluid requirements, adverse events, and time to motor recovery (modified Bromage score of 2). Results Group S had a lower intraoperative sensory block height than Group L [T4 (1) vs T2 (1), respectively; P.001]; Group S also required less ephedrine (8% vs 47%, respectively; P.001), received less fluid [709 (59) mL vs 789 (90) mL, respectively; P.001], and experi- enced less nausea and vomiting (5% vs 22%, respectively; P = 0.014) and shortness of breath (3% vs 28%, respec- tively; P.001) intraoperatively. In Group S, the odds of requiring ephedrine were 0.09 compared with 0.89 in Group L (odds ratio 0.10). There were no differences in systolic blood pressure (P = 0.127) or heart rate (P = 0.831) over time between groups. Time to a modified Bromage score of 2 was longer in Group S than in Group L [101 (15) min vs 88 (14) min, respectively; P.001]. Conclusions Sitting the patient up for five minutes rather than laying the patient down immediately after spinal anesthesia for Cesarean delivery decreased intraoperative sensory block height, ephedrine and fluid requirements, and intraoperative nausea, vomiting, and shortness of breath without affecting systolic blood pressure or the success of the anesthetic. However, the method resulted in delayed postoperative motor recovery.

Melasma is a common aesthetic problem characterized by facial hyperpigmentation. It frequently affects young to middle-aged females who are Hispanic or of Asian, African or Middle Eastern descent. Its pathogenesis is still mysterious with multiple factors are being accused to play a role. Although many treatment options are currently available, melasma is difficult to cure with tendency to relapse. Melasma (a term derived from the Greek word “melas” meaning black) is a worldwide prevalent acquired disorder of hyperpigmentation that commonly affects females with Fitzpatrick skin phototypes III-V (Goh and Dlova, 1999 and Gupta et al., 2006). It is characterized by appearance of symmetrical light to dark brown spots and patches on sun exposed areas mostly the face and especially the forehead, cheeks and chin (Kang and Ortonne, 2009). Melasma is sometimes termed chloasma (derived from the Greek word “chloas” meaning green) or mask of pregnancy when it develops in pregnant females (Handel et al., 2014a).
