The Folstein Mini Mental State Examination (MMSE) has been used by clinicians as a cognitive screening tool for its convenience, even though it is not sensitive, and often fails to detect cognitive impairment. Recently, the Montreal Cognitive Assessment (MoCA) has been developed as a brief cognitive screening tool to detect mild-moderate cognitive impairment. We performed a longitudinal study to compare the utility of the MMSE and MoCA in an inpatient rehabilitation setting. A total of 50 consecutive patients were studied with an average age of 71.7 years of age. The mean test score for MMSE was 26.5 and 22.2 for the MoCA. The Pearson’s correlation coefficient between the scores was 0.695 (p < 0.003). The mean performance time for the MMSE was 7.4 minutes and 14.8 minutes for the MoCA. MMSE did not perform well as a screening instrument for mild cognitive impairment as there were 43 patients who scored 24 or more on MMSE, and 25 patients (58%) scored 25 or less on MoCA, indicating the presence of cognitive impairment. Even though the MoCA takes longer to administer, the additional important information provided indicates that the MoCA should be used rather than the MMSE as a cogni-tive screening tool.展开更多

Our group has already described the relationship between body weight and hyperphosphatemia with these preparations, although our study was not quoted by Casals. We performed a pharmacokinetic study involving 13 volunteers who were divided into two groups on the basis of body weight: group I consisting of seven women with a median weight of 60 kg and group Ⅱ consisting of five men and one woman with a median weight of 119.2 kg. Group Ⅰdeveloped higher peak phosphate levels and maintained these levels above the subjects in Group Ⅱ for a prolonged time period despite adequate hydration being ensured with frequent monitoring of weight, fluid intake and total body weight. Our studydemonstrated that adequate hydration does not protect against the secondary effects of hyperphosphatemia. In the study by Casais et al, 66% of the study subjects were women, the correlation between serum phosphate and gender in their data also appears to be important. Women are at higher risk of acute phosphate nephropathy due to a diminished volume of distribution of the high dose of ingested phosphate. Decreased volume of distribution in women is due to diminished body weight. This is further compounded by decreased creatinine clearance in females.展开更多

Case presentation: A 27-year-old primigravid lady, previously healthy, at 40 weeks + 2 days presented to a midwife’s clinic for routine antenatal consultation. She was advised to have induction of labor. This was initiated with 2 tablets of Misoprostol (400 mcg) vaginally. Twelve hours later, and after remaining at full cervical dilation for 4 hours, she was referred to our maternity service for alleged failure to descend. On arrival, she was apprehensive, exhausted but hemodynamically stable. Pelvic exam disclosed a fully dilated cervix with the vertex at S + 1 and a caput reaching the introitus. No fetal heart rate could be elicited by the CTG monitor and this was verified by a bedside ultrasonography. Operative vaginal delivery was performed due to maternal exhaustion. This was complicated by transient shoulder dystocia. Manual revision of the birth canal and the uterine cavity disclosed a suspicion of left vaginal vault gapping together with a left fundal uterine rupture. Consequently, the patient was rushed to the operating room for an urgent exploratory laparotomy. The rupture sites were identified and repaired while a large broad ligament hematoma on the same side was explored and hemostasis secured with ipsilateral uterine artery ligation of the fundal and cervical branches. The postoperative course was smooth and the patient left the hospital on the 5th day postpartum. Conclusion: Cases of unscarred uterine rupture are limited. One of the most frequent risk factor is the injudicious use of Misoprostol for labor induction. Sudden arrest of progress of labor or failure to descend might mask uterine rupture. We recommend that all birth attendants be familiar with the guidelines issued by FIGO, ACOG and other societies for the safe use of these potent uterotonics.展开更多

Small distal fragment, diminished bone mineral quality and increased trauma-associated joint destruction make stable joint reconstruction more problematic. The anatomically preshaped locking plates allow angular stable fixation for these complex fractures. We evaluated functional results of patients treated with open reduction and internal fixation with distal humerus locking plates for complex distal hu- merus fractures. Methods: Forty-three consecutive patients with ar- ticular fractures of the distal humerus were treated by open reduction and internal fixation with AO distal humerus plate system and locking reconstruction plates. Forty patients were available for the final outcome analysis. According to AO/ASIF classification, there were 2 cases of type A2, 4 cases of type A3, 1 case of type B1, 1 case of type B2, 14 cases of type C1, 7 cases of type C2 and 11 cases of type C3. Open reduction with triceps splitting technique was used in all patients. The clinical and radiographic follow-up was performed and outcome measures included pain assessment,range of motion, and Mayo elbow performance score. Results: Forty patients were available for the final outcome analysis. There were 29 males and 11 females with an average age of 38.4 years (18-73 years). Clinical and ra- diological consolidation of the fracture was observed in all cases at an average of 11.6 weeks (9-14 weeks). The average follow-up was 12 months (10-18 months). Using the Mayo elbow performance score the results obtained were graded as excellent or good results in 33 patients (82.5%). One pa- tient had superficial infection, and 4 had myositis ossificans. There were no cases of primary malposition or secondary displacement, implant failure or ulnar neuropathy. Conclusion: Anatomically preshaped distal humerus locking plate system is useful in providing stable fixation for complex distal articular fracture and facilitating early post- operative rehabilitation. The low rate of implant failure in the present study indicates that the technique is promising and warrants further investigation.展开更多
