Buttock necrosis and paraplegia after bilateral internal iliac artery embolization for postpartum hemorrhage.

BACKGROUND: Endovascular embolization has become part of the management of postpartum hemorrhage. CASE: We report a case of bilateral extensive gluteal skin and muscle necrosis with concurrent severe lumbosacral plexopathy after bilateral internal iliac artery embolization for postpartum hemorrhage. The ischemic plexopathy was treated conservatively, with a fair outcome. The complex gluteal wound was treated successfully with debridement and skin grafting. CONCLUSION: Pregnancy is known to increase the pelvic collateral blood vessels, and, hence, such a complication in a healthy pregnant woman is extremely rare. The risk of such a severe complication may be minimized by more selective embolization.

The prognostic value of concurrent Horner syndrome in extended Erb obstetric brachial plexus palsy.

Horner syndrome may be seen in infants with extended Erb obstetric brachial plexus palsy. However, its prognostic value in these infants has not been previously investigated. A total of 220 infants with extended Erb palsy were included and divided into 2 groups: group I (n = 209) were infants with extended Erb palsy without Horner syndrome, and group II (n = 11) were infants with extended Erb palsy and concurrent Horner syndrome. The rate of good spontaneous recovery of elbow flexion was 59% in group I and 27% in group II, and the difference was significant (P = .038). The rate of good spontaneous recovery of wrist extension was 61% in group I and 0% in group II, and the difference as highly significant (P < .0001). Concurrent Horner syndrome in infants with extended Erb palsy may be considered as a poor prognostic sign for recovery of the sixth and seventh cervical roots.

A case of Klumpke's obstetric brachial plexus palsy following a Cesarean section

It is generally thought that Klumpkes palsy is not seen as obstetric injury. The authors present a case of Klumpkes palsy with Horner syndrome following delivery by emergency Cesarean section. Neurolysis and nerve grafting partially corrected the paralysis.

Obstetric brachial plexus palsy following routine versus difficult deliveries.

Previous bio-engineering studies showed that intrapartum peak forces applied by the clinician were lower in routine deliveries than difficult deliveries. A total of 751 cases of obstetric brachial plexus palsy were included and divided into two groups: group I (248 patients) were born following routine deliveries and group II (503 patients) were born following difficult deliveries. Both groups were compared regarding the type of palsy and the rate of good/poor spontaneous motor recovery from the palsy. Group I subjects were more likely to have upper Erb palsy whereas those in group II were more likely to develop total palsy (P < .0001). The percentage of newborns with poor functional recovery was significantly higher (P < .05) in group II with regards to shoulder, wrist, and hand function. It was concluded that higher peak forces applied by the clinician in difficult deliveries affect the type of obstetric brachial plexus palsy.

Serum adipokines (adiponectin and resistin) correlation in developing gestational diabetes mellitus: pilot study

Abstract Adiponectin and resistin are adipose tissue-derived proteins with antagonistic actions; adiponectin has insulin sensitive properties while resistin is involved in the development of insulin resistance. We analyzed adiponectin and resistin levels in gestational diabetes mellitus (GDM) women to evaluate the association of these adipokines in a very high diabetes prevalence population. An age-matched case-control study of GDM and normal pregnant women in Saudi population. We recruited 90 pregnant women at 24–32 weeks of gestation. Glucose levels (fasting, 1, 2, and 3 h) and lipid parameters (cholesterol, triglyceride, HDL cholesterol, LDL cholesterol) were measured. Serum adiponectin and resistin levels were analyzed using Randox evidence biochip analyzer. Pearson’s correlation coefficient was used to determine the association of adiponectin and resistin with GDM risk factors. GDM women showed significantly low adiponectin and high resistin levels when compared with control group. Pearson’s correlation analysis of adiponectin and resistin in all the subjects with various GDM risk factors showed a negative association of adiponectin (r = −0.32, p = .05) and a positive correlation of resistin (r = 0.41, p = .01) with LDL cholesterol. This study analyzes adiponectin and resistin levels together, as accumulating evidences shows that these are involved in the pathophysiology of GDM. This is going to help to determine in conjunction with traditional risk factors the incremental value of circulating adiponectin and resistin in developing GDM.

Intravenous Access in Infants Undergoing Bilateral Sural Nerve Grafts for Primary Brachial Plexus Exploration

Background: Intravenous access (IVA) in infants undergoing primary brachial plexus exploration may be difficult. Both lower limbs are prepared and draped for sural nerve graft harvesting. The injured upper limb is also prepared and draped and is not available for IVA. In difficult IVA from the remaining upper limb, we have been using one of the feet for IVA. The infection rate and problems of intravenous infusions in this setting have never been studied in the literature. This study documents the infection rate and problems of intravenous infusions in these infants when a foot (within the sterile field) is used for IVA. Methods: This is a retrospective study of 63 consecutive infants undergoing primary brachial plexus exploration, and in whom IVA was obtained from one of the feet. Infection rate and problems of intravenous infusions were recorded. Results: No surgical wound infection and no infection of the IVA site were noted. There were no instances of accidental dislodgement of the intravenous cannula and no instances of extravasation. Conclusion: The use of one of the feet (within the sterile filed) for IVA is safe and acceptable in infants undergoing primary brachial plexus exploration and bilateral sural nerve grafting.

Intraoperative Nerve Stimulation During Brachial Plexus Surgery: Comparison Between a Totally Disposable Nerve Stimulator and Nerve Stimulator Normally Used for Nerve Blocks

Background: Intraoperative nerve stimulation is done routinely in brachial plexus and peripheral nerve surgery as well as in selective neurectomy in spastic patients. Objective: The current study compares the use of 2 different devices for nerve stimulation: a totally disposable nerve stimulator and a nerve stimulator used for nerve blocks by anesthetists. Methods: A retrospective study of 60 patients who underwent brachial plexus surgery: In 30 patients, we used the totally disposable nerve stimulator (group 1) and in another 30 patients, we used the anesthesia device (group 2). The cost of disposable materials used for nerve stimulation was calculated in each group. The same surgeon performed all operations, and he was asked to give his subjective opinion regarding the convenience and ease of use of the device in each group. Results: The main advantages of the totally disposable device are its placement totally within the sterile field, and it is operated by the surgeon without the need to communicate with the anesthetist. However, the totally disposable device had several major disadvantages when compared to the anesthesia device. Firstly, the disposable stimulator can only deliver 0.5, 1.0, and 2.0 mA stimuli, while the anesthesia device can deliver stimuli of 0.1 to 5 mA (in 0.1 mA increments). Secondly, the disposable stimulator frequently fails to operate during surgery, and this is not experienced with the anesthesia device. Finally, the cost of disposables is less using the anesthesia device. Conclusion: Our center has stopped using the disposable nerve stimulator in favour for the anesthesia device.

Evidence of the Effectiveness of Primary Brachial Plexus Surgery in Infants With Obstetric Brachial Plexus Palsy–Revisited

A recent systematic review questioned the effectiveness of primary surgery in infants with obstetric brachial plexus palsy. At our center, the indication for primary surgery in infants with upper Erb’s obstetric palsy is the lack of active elbow flexion at age 4 months. The current study compares the outcome of motor recovery in 2 groups of infants with upper Erb’s palsy: one group (n = 9) treated surgically between age 4 and 5 months, and another group (n = 9) treated conservatively despite the lack of active elbow flexion at age 4 months. The only reason for not doing the surgery in the latter group was refusal by the parents. The scores of motor recovery were collected at the 2-year follow-up visit, and they were significantly better in the surgical group. The study demonstrates the effectiveness of primary surgery in infants with upper Erb’s obstetric palsy compared to conservative management.
