Evaluation of the effectiveness and safety of combined oral and topical photoprotection with a standardized extract of Polypodium leucotomos (Fernblock®) in a Moroccan population with xeroderma pigmentosum.

BACKGROUND: Xeroderma pigmentosum (XP) is a rare autosomal-recessive genodermatosis resulting from a DNA-repair defect syndrome. The purpose was to evaluate the prevention on new malignant lesions in patients taking a supplement with Fernblock® (Polypodium leucotomos extract [PLE]) and secondarily correlation with the photoprotective behavior. METHODS: A prospective, single-center and open cohort study was conducted over a 12-month period. The study was performed in Morocco. Optimal photoprotection behavior was recommended. Patients were instructed to take one capsule containing 480 mg of Fernblock® and 5 mcg vitamin D and to apply sunscreen with a SPF50+ and Fernblock® every 2 h during sun exposure. The demographic, clinical, and dermatoscopic patient data were collected at baseline (T0) and following visits at 3 months (T3), 6 months (T6), and 12 months (T12) when it was assessed: Investigator Global Assessment (IGA), Patient/Guardian Global Assessment (PGA), Patient/Guardian Satisfaction Questionnaire, and Photographic and Adverse Events Registration. Pertinent statistical study was performed. RESULTS: Eighteen patients completed the study. Eleven patients (61%) finished the study without new lesions. Seven patients developed new lesions by the end of the study. Among them, only 30% showed an ideal photoprotective behavior. The lack of an optimal photoprotective behavior increased the probability of developing lesions by 2.5 times with 95% confidence interval. CONCLUSIONS: In our study, more than 60% of patients taking a supplement with Fernblock® did not develop new lesions, and furthermore, we detected that patients following almost ideal photoprotection were 2.5 times less likely to develop NMSC lesions.

Size-Specific Dose Estimates for Thoracic and Abdominal Computed Tomography Examinations at Two Moroccan Hospitals.

Size-specific dose estimates (SSDE) are the latest topic of interest in patient radiation-dose studies in computed tomography (CT). The aim of this study is to calculate and evaluate the doses (SSDE) by measuring the effective diameter (ED) of cross-sectional images collected during CT examinations of the chest and abdomen in Moroccan hospitals. Doses (SSDE) were calculated based on cross-sectional images by measuring the effective diameters of 75 patients in both examinations (45 for the thorax and 30 for the abdomen). Specific conversion factors for (ED) were used to convert the registered CTDIvol to SSDE, according to the instruction in the American Association of Physicists (AAPM) Report 204. In thoracic CT, the CTDIvol and SSDE values ranged from 5.8 to 10.7 mGy (mean: 8.08) and 9.55 to 15.37 mGy (mean: 12.13), respectively. For abdominal CT, CTDIvol and SSDE values ranged from 4.8 to 12.2 mGy (mean: 7.95) and 8.01 to 14.15 mGy (mean: 11.31), respectively. The results show that the SSDE is a useful tool and could potentially educate CT operators on its effective use as a way to optimize radiation dose instead of CTDIvol, in particular to establish diagnostic reference levels.

[Sigmoid volvulus, a rare complication of pregnancy]. / Volvulus du sigmoïde, une complication rare de la grossesse.

Sigmoid volvulus complicating pregnancy is a rare complication with less than 80 cases reported in literature. We report the case of a young pregnant woman, admitted for sigmoid volvulus. The sigmoid volvulus was resected and Bouilly-Volkmann's colostomy was performed. According to this case and depending on the literature, the authors discuss the diagnostic and therapeutic modalities proposed for this rare entity.

Effect of epidural clonidine added to epidural sufentanil for labor pain management.

Labor analgesia with intrathecal sufentanil has been shown to be prolonged by the addition of intrathecal clonidine. The current study was designed to determine if epidural clonidine would prolong labor analgesia provided by epidural sufentanil. Forty laboring primiparous women at less than 5 cm cervical dilation requesting epidural analgesia were enrolled. Following a 3 mL test dose of lidocaine with epinephrine, patients were randomized to receive 10 mL of either sufentanil 20 microg (S) or sufentanil 20 microg with clonidine 75 microg (SC). After administration of the analgesic, pain scores and side-effects were recorded for each patient at 5, 10, 15, 20 and 30 min, and every 30 min thereafter, by an observer blinded to the technique used. There were no demographic differences between the two groups. Pain relief was rapid for all patients. The mean duration of analgesia was similar between the S group (153 +/- 78 min) and the SC group (178 +/- 55 min). Side-effects were similar between the two groups. There was no difference between the two groups in time from sufentanil administration to delivery, incidence of operative or assisted delivery, or cervical dilation at the time of redose. For early laboring patients, epidural sufentanil 20 microg after a lidocaine test dose provides analgesia comparable to that of sufentanil 20 microg with clonidine 75 microg; there was no significant difference in analgesic duration between the two groups.

Transmesocolic internal herniation: a rare case of small bowel obstruction, "the Marrakesh hernia".

Internal hernias, including paraduodenal (traditionally the most common), pericecal, foramen of Winslow, and intersigmoid hernias, account for approximately 0.5-5.8% of all cases of intestinal obstruction and are associated with a high mortality rate, exceeding 50% in some series. We report an extremely rare case of an internal abdominal hernia, through the right mesocolon, in a young woman with a right colon with no peritoneal fixation. This hernia was revealing by abdominal pain, nausea, and vomiting. The diagnosis of internal hernia was suggested by computed tomography (CT), but the exact type of internal hernia was confirmed by surgical exploration. The postoperative course was uneventful and the patient fully recovered after 3 days. The patient is free from symptoms and from recurrence, after 12 months of follow-up.

The preemptive analgesic effect of intraarticular bupivacaine and morphine after ambulatory arthroscopic knee surgery.

UNLABELLED: Intraarticular (IA) morphine provides effective postoperative analgesia after arthroscopic knee surgery. Some investigators have suggested that the preemptive administration of opioids may reduce postoperative analgesic requirements and hypersensitivity. We evaluated the analgesic effect of administering IA morphine either before or after surgical incision in patients undergoing arthroscopic knee surgery under local anesthesia. Forty patients undergoing arthroscopic meniscectomy were randomized into two groups. All patients received IA bupivacaine 0.25% before and after surgery together with IV sedation using midazolam and propofol. The Preemptive IA Morphine group received a single 3-mg dose of morphine with their preoperative bupivacaine. The Post-IA Morphine group received 3 mg of morphine at the completion of surgery with the postoperative bupivacaine. After surgery, pain scores, the time to first opioid use, and 24-h analgesic use were recorded. Analgesic duration, defined as the time from completion of surgery until first opioid use, was significantly longer in those patients receiving preoperative (953 +/- 209 min) versus postoperative (556 +/- 121 min) IA morphine. The 24-h acetaminophen and oxycodone use was less in the Preemptive group (2.2 +/- 1.2 pills) versus the Postoperative group (3.0 +/- 1.2 pills). We conclude that IA morphine provides a longer duration of postoperative analgesia with less 24-h opioid use when administered before surgery. IMPLICATIONS: The administration of intraarticular morphine 3 mg before arthroscopic knee surgery provides a longer duration of analgesia with less 24-h opioid use compared with the administration of the drug at the completion of surgery.

The influence of a bupivacaine and fentanyl epidural infusion after epidural fentanyl in patients allowed to ambulate in early labor.

UNLABELLED: Epidural fentanyl after a lidocaine and epinephrine test dose provides adequate analgesia and allows for ambulation during early labor. This study was designed to determine the influence of an epidural infusion of bupivacaine plus fentanyl administered after initiation of epidural labor analgesia with fentanyl. Specifically, we evaluated whether there is an increase in motor block or an increased time to request for further analgesic medication. Fifty-one laboring primigravid women at <5 cm cervical dilation who requested epidural analgesia were enrolled. After a 3-mL epidural test dose of 1.5% lidocaine with epinephrine (5 microg/mL), patients received fentanyl 100 microg via the epidural catheter. They then randomly received either an infusion (10 mL/h) of 0.0625% bupivacaine with fentanyl (3 microg/mL) or an infusion of preservative-free saline. After the administration of the initial analgesic, pain scores and side effects were recorded for each patient at 10, 20, and 30 min, every 30 min thereafter, and at the time of request for additional analgesic medication, by an observer blinded to the technique used. There were no demographic differences between the two groups. The mean duration of analgesia (time from initial dose to request for additional analgesia) was increased in the group that received a continuous infusion of bupivacaine and fentanyl compared with the Saline group (198 +/- 86 vs 145 +/- 50 min; P < 0.009). Side effects were similar between the two groups. No patient in either group experienced any detectable motor block. Fourteen patients chose to ambulate in the Saline group, and 12 patients chose to ambulate in the Infusion group. In early laboring patients, a continuous infusion of 0.0625% bupivacaine infusion with fentanyl (3 microg/mL) prolonged the duration until top-up was required, after epidural fentanyl 100 microg after a lidocaine and epinephrine test dose, and did not cause any clinically detectable motor block. IMPLICATIONS: A 0.0625% bupivacaine and fentanyl (3 microg/mL) infusion, when added to epidural fentanyl (100 microg), prolongs the analgesic duration without increasing motor block in women in early labor.
