    Forty-one aged Jersey cows were fed a high Ca diet prior to parturition to predispose them to parturient paresis. Twenty-one of the cows were treated with 24-F-1,25-dihydroxyvitamin D3, a synthetic analogue of 1,25-dihydroxyvitamin D3, 7 d before the expected parturition. Treated cows received either 100 micrograms (n = 7) or 150 micrograms (n = 14) of 24-F-1,25-dihydroxyvitamin D3, intramuscularly at 7-d intervals until the cow calved. Incidence of parturient paresis among untreated animals was 85% (17/20). Injections of 100 micrograms of 24-F-1,25-dihydroxyvitamin D3 reduced the incidence of parturient paresis to 43% (3/7), whereas 150 micrograms injections of 24-F-1,25-dihydroxyvitamin D3 reduced the incidence of parturient paresis to 29% (4/14). Plasma concentrations of hydroxyproline were not elevated prior to parturition in 24-F-1,25-dihydroxyvitamin D3-treated cows, indicating that treatment did not stimulate bone resorption and that the ability of 24-F-1,25-dihydroxyvitamin D3 to prevent parturient paresis likely resides in its ability to stimulate intestinal Ca absorption prior to parturition. Further, cows treated with 24-F-1,25-dihydroxyvitamin D3 that developed parturient paresis had lower than normal plasma concentrations of 1,25-dihydroxyvitamin D, indicating that 24-F-1,25-dihydroxyvitamin D3 treatment impairs the metabolism of 25-hydroxyvitamin D in response to hypocalcemia. These data suggest that injection of 24-F-1,25-dihydroxyvitamin D3, delivered at 7-d intervals prior to parturition, can effectively reduce incidence of parturient paresis in dairy cows.

    Parturient paresis (milk fever) is a hypocalcemic disorder caused by the onset of lactation in the dairy cow. In most cows a complete recovery follows a single iv calcium treatment to correct the acute hypocalcemia. However, about 20% of cows treated for parturient paresis experience recurring episodes of hypocalcemia (relapses) requiring further treatment. Analysis of plasma from 8 nonrelapsing parturient paretic and 11 relapsing parturient paretic cows revealed differences in plasma 1,25-dihydroxyvitamin D [1,25-(OH)2D] concentrations before and during the development of hypocalcemia. In nonrelapsing cows, plasma 1,25-(OH)2D increased to 4- to 5-fold as plasma calcium concentrations declined during the first stage of parturient paresis. In relapsing cows, decreases in plasma calcium concentrations during the first stage of parturient paresis were accompanied by just a 2- to 2.5-fold increase in plasma 1,25-(OH)2D. Plasma 1,25-(OH)2D eventually increased 4- to 5-fold in the relapsing cows, but this response was delayed 24-48 h compared with the response in the nonrelapsing cows. Plasma PTH concentration profiles were similar in relapsing and nonrelapsing cows, suggesting that renal 25-hydroxyvitamin D 1 alpha-hydroxylase was temporarily refractory to stimulation by PTH in the relapsing cows. In both groups of cows recovery from parturient paresis began about 12-24 h after plasma 1,25-(OH)2D concentrations had increased 4- to 5-fold. These data imply that lack of production of 1,25-(OH)2D is an important factor in predisposing the cow to relapses of parturient paresis and is critical for recovery from the hypocalcemia associated with the onset of lactation.

    The goal of this study was to investigate the efficacy of calcium chloride, sodium phosphate or a combination of these two substances administered orally immediately postpartum for the prevention of parturient paresis in cows. Thirty-two cows that had had parturient paresis at the previous calving, and in which serum biochemistry had shown hypocalcaemia and hypophosphataemia, were used in the study. The cows were transferred to the Department of Farm Animals, University of Zurich, five days before their expected due dates. On a randomized trial, the cows were given calcium chloride, sodium phosphate, both substances or no treatment (controls) via a stomach tube immediately postpartum and 12 hours later. The cows were monitored for 96 hours during which time blood was collected on a regular basis for the determination of total calcium, ionized calcium, inorganic phosphorus and magnesium concentrations. Of the 32 cows treated, 19 (59%) had parturient paresis and 13 (41%) did not. The incidence of parturient paresis did not differ significantly among the groups although there was a tendency for a lower incidence in cows treated with both calcium chloride and sodium phosphate. The various treatments had no apparent effect on serum calcium concentration. The concentration of inorganic phosphorus increased significantly in cows treated with sodium phosphate compared with the controls. The results of this study showed that cows treated with both calcium chloride and sodium phosphate orally tended to have a lower incidence of parturient paresis. Further investigation into multiple administrations of oral calcium chloride and sodium phosphate, started before parturition, for the prevention of parturient paresis is required. PMID:18714936

    The goal of this study was to determine whether oral administration of sodium phosphate in conjunction with intravenous calcium is more efficaceous than intravenous calcium alone for the treatment of parturient paresis. Thirty cows with parturient paresis were examined and treated by the same veterinarian. The cows were divided randomly into two groups of 15 cows each. Cows in group A received 500 ml of a 40 per cent calcium borogluconate solution containing 15.65 g calcium gluconate and borogluconate, with a supplement of 6 per cent magnesium hypophosphite (9.85 g magnesium hypophosphite) intravenously over a period of approximately 15 min. Cows in group B received the same treatment as well as 350 g of monobasic sodium phosphate (70 g inorganic phosphate, NaH2PO4 2 H2O, Streuli) dissolved in 0.5 litres of distilled water orally via a stomach tube. After treatment, the heart rate, respiratory rate, rectal temperature, superficial body temperature, rumen motility, appetite and defecation of the cows were monitored every hour for eight h. The cows' attempts to rise and their ability to stand were also noted. Initially, the results of clinical examination and serum electrolyte analyses did not differ between the two groups of cows. Within one hour of treatment, stupor was not observed in any of the cows. The general demeanour after treatment did not differ significantly between the two groups. In both groups, the average rectal temperature increased within two hours of the initiation of treatment, from 38.0 +/- 0.95 degrees C to 38.5 +/- 0.40 degrees C. There was no significant difference in the recovery rate between the groups. Of the 30 cows, 22 (73.3 per cent) stood within eight hours of treatment (10 cows from group A and 12 cows from group B). The type of treatment did not affect the time required to stand: cows in group A stood within 47.3 +/- 44 minutes and cows in group B stood within 24.2 +/- 32 minutes after the start of treatment.

    The role of dietary calcium concentration during the feeding of anionic salts (AS) was reviewed. Hypocalcaemia is still the major cause of parturient paresis in dairy cows. Feeding AS is an established method for preventing severe hypocalcaemia by activating the calcium metabolism in the last two to three weeks before parturition by inducing a metabolic acidosis. In compensation for this acidosis, the organism increases the concentrations of ionised Ca [Ca2+] in the blood. This increase leads to an increasing excretion of calcium via the urine, which is ensued by an increased calcium absorption in the intestine. The ongoing metabolic acidosis changed the flux of Ca. The size of the Ca pool, however, remained unchanged. As the calcium metabolism is activated by AS, it seems necessary to increase the amount of calcium that is fed to the cows. Several studies examined the impact of different dietary calcium concentrations on the acid-base balance and the calcium metabolism in cows fed anionic salts. The study designs vary concerning the amounts of calcium fed and the use of pregnant or non-pregnant cows. Only one study combined the feeding of AS with a very low amount of calcium, which fell below the daily requirements of pregnant cows in the last three weeks before parturition. In this study, the calcium balance post partum was better in the cows that were administered AS and a high calcium diet. In the other studies, the amount of calcium in the different experimental groups and the difference between the amounts of calcium fed varied greatly. As far as it was monitored in the studies, the calcium concentration of the diet did not have a significant impact on the degree of acidosis induced by AS. In pregnant cows, no significant differences in the calcium concentration in serum or urine occurred before parturition. Some of the researchers found a lower incidence of parturient paresis when cows were fed a combination of AS and a higher amount of calcium, but some

    The effectiveness of a combination of 1 alpha-hydroxyvitamin D3 and 25-hydroxyvitamin D3 for reducing incidence of parturient paresis in aged Holstein cows was tested. Intramuscular injection of .5 mg of 1 alpha-hydroxyvitamin D3 plus 4 mg of 25-hydroxyvitamin D3 increased plasma 1,25-dihydroxyvitamin D concentrations through parturition. Treatment with 1 alpha-hydroxyvitamin D3 plus 25-hydroxyvitamin D3 raised prepartum serum Ca approximately 2 mg/dl and prepartum serum P approximately 4 to 5 mg/dl higher than untreated controls. Both treated and control cows had approximately a 2-mg/dl decrease in serum Ca following parturition. The prepartum diet of alfalfa silage and hay was supplemented with a grain mixture supplying 100 g of Ca/d from ground limestone. Under these dietary conditions, incidence of parturient paresis was reduced from 33 to 8%. In a separate experiment, treatment with 1 alpha-hydroxyvitamin D3 plus 25-hydroxyvitamin D3 did not reduce incidence of parturient paresis when cows consumed mixed diets of different feed-stuff composition. Further experiments are required to determine specifically the factor or factors responsible for the difference in response to active vitamin D compound administration between the two experiments. Prepartum dietary Ca intake may be one such factor. PMID:1560144

    1993-06-01

    Intramuscular injection of 1 alpha-hydroxyvitamin D3 (with or without 25-hydroxyvitamin D3) to highly pregnant dairy cows caused a significant increase of ionized calcium in blood and of total calcium and inorganic phosphate with a concomitant decrease of magnesium in blood plasma 3,5 +/- 1,9 days later (resp. 12-48 h a.p.). This brought about a higher Ca level at parturition preventing parturient paresis. The changes of maternal mineral and vitamin D status had no effect on the mineral concentrations of blood in newborn calves. However, the increase in calcium and phosphate concentrations in maternal blood after injection was accompanied by an increase of the minerals in the amniotic fluid reflecting their strong reciprocal exchange. On the other hand, the composition of allantoic fluid showed no significant changes. Therefore, analysis of both fetal fluids does not refer to disorders of fetal mineral metabolism. As a consequence, there seems to be no potential risk of intoxication after a prepartal injection of the substances to the mother for their offspring. PMID:8343105

Magnetic resonance imaging disclosed a unilateral embolic infarction restricted to the mesodiencephalic junction involving the left paramedian thalamus. Preserved vertical oculocephalic movements and intact Bell's phenomenon suggested a supranuclear lesion. This rare "crossed vertical gaze paresis" results from a lesion near the oculomotor nucleus affecting ipsilateral downward gaze and contralateral upward gaze fibres, originating in the rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF).

    Paresis and paralysis are uncommon problems in sheep but are likely to prompt farmers to seek veterinary advice. A thorough and logical approach can aid in determining the cause of the problem and highlighting the benefit of veterinary involvement. While this may not necessarily alter the prognosis for an individual animal, it can help in formulating preventive measures and avoid the costs – both in economic and in welfare terms – of misdirected treatment. Distinguishing between central and peripheral lesions is most important, as the relative prognoses are markedly different, and this can often be achieved with minimal equipment. This article describes an approach to performing a neurological examination of the ovine trunk and limbs, the ancillary tests available and the common and important causes of paresis and paralysis in sheep.

    Caring for the Jehovah's Witness parturient is a complex task that presents a number of ethical, medical, and legal concerns because many Jehovah's Witnesses refuse allogeneic blood transfusion. Childbirth and its surrounding events may be associated with significant blood loss. Given their significant role in the intraoperative administration of blood products, anesthesia providers should be familiar with factors that must be considered in the perioperative care of Jehovah's Witness parturients. Several pharmacologic therapies, anesthetic techniques, and operative interventions aimed at blood conservation may be useful in the care of such patients. Aside from their refusal of transfusion, each Witness makes a personal decision on the acceptability of derivatives of plasma or cellular blood components and autologous blood management. Therefore, the patient-physician relationship must ensure that the individual patient's desires are accurately communicated, respected, and documented in the patient's medical record. The Perioperative Surgical Home model is appropriate for use in caring for Jehovah's Witness patients because it allows for the early and continuing coordination of care and communication between the patient and a multidisciplinary team. In this article, we present a focused review of concepts important to the provision of anesthetic care of parturients who are Jehovah's Witnesses and introduce an algorithmic perioperative approach that may be applied to the care of the Jehovah's Witness parturient undergoing an operative procedure.

    The incidence of paresis due to herpes zoster (HZ) infections are reported very differently in the literature with rates varying from 0.5 to 31%. Many of the paresis are presumed to be undiagnosed on account of topographic dissociation, variable periods from the cutaneous affection to the muscular involvement, masking of the paresis by pain, paresis of the intercostal and abdominal muscles which are not obvious and difficulties in correlating the visceral symptoms with a herpes zoster eruption. Paresis of the cranial nerves are easily diagnosed and 50% of all HZ paresis are diagnosed from this region. Early acyclovir treatment has improved the prognosis. Four cases of hypotonic herpes zoster paresis in immunocompetent persons are described and the diagnostic difficulties are discussed. PMID:2158682

    We analyzed the effects of 2.0-g, 1.75-g and 1.5-g hypergravity exposure on plasma concentrations of the lactotrophic hormone, prolactin (PRL), in female rats on pre-parturient (Gestation Day 20), parturient (Post-natal day 0) and lactating (P10) days. PRL levels have been found to be reduced in rat dams around the time of birth following exposure to gravitational loads varying from 2.16 to 3.14-g (Megory et. al., Aviation, Space and Environs 1129-1135, 1984). It has also been reported that at these high gravitational loads, neonatal mortality has been extremely high, suggesting a possible interaction between dam PRL concentration and neonatal outcome. We have previously reported no significant differences in PRL levels of parturient (PO) and lactating (P6 & P 15) dams when exposed to 1.5-g hypergravity, but did observe a slight elevation of PRL on PO and P 15, with a decrease on P6. In the present study, time-bred pregnant dams were exposed to either continuous 2.0-g, 1.75-g or 1.5-g centrifugation, beginning on Gestational day (G) 11 of the rats' 22-day pregnancy. We observed no significant differences in PRL concentrations between SC and any of the HG conditions. On G20 and PO, PRL concentrations of the 2.0-g and 1.5-g groups were slightly elevated as compared to SC. Similar to what we previously reported. PRL secretion was elevated in both HG and SC conditions on the day of birth relative to later during lactation, but on P10 it appeared to be reduced in HG relative to SC dams. These findings suggests that hypergravity slightly elevates plasma concentration of PRL in pre-parturient and lactating rat dams, with effects most pronounced during the periparturitional period and in a direction opposite to that observed following microgravity exposure.

    Herpes zoster is an infectious disease with neurological complications caused by reactivation of varicella zoster virus in dorsal root ganglia of spinal cord which is also known as “Shingles.” Suppression of immune system is the major predisposing factor for reactivation of latent virus. Disease is mainly characterized by rash, vesicles and pain along one or more dermatomes which are innervated from one or more spinal nerve roots. Complications may be present after a while despite of patient treatment. Motor involvement is included. Some previous studies showed segmental zoster paresis as a rare complication, a few weeks after first presentation, among immunocompetent individuals. We present post herpetic motor involvement of C5 and C6 in a 59-year-old woman who underwent chemotherapy and radiotherapy due to breast cancer, manifesting left upper limb weakness and paresis, 6 months after left partial mastectomy. Segmental paresis of zoster virus should be considered as a cause of motor impairment in an immunocompromised person suffering from shingles. PMID:26436084

    Herpes zoster is a common presentation in both the community and emergency department; however segmental zoster paresis is a rare complication that can lead to misdiagnosis. We present a case of a 74-year-old Indian gentleman with a background of well controlled diabetes mellitus, hypertension, and ischaemic heart disease who presented with sudden right lower limb weakness. This was preceded by a 5-day history of paraesthesia starting in the right foot and ascending up the right lower limb. On examination, there was a characteristic vesicular rash in the L2/3 region with MRC grading 3/5 in the right hip flexors. The rest of the neurological examination was unremarkable. MRI of the spine did not show any evidence of spinal disease. The patient was initiated on IV acyclovir with improvement of the lower limb weakness to MRC grading 5/5 as the vesicles improved. This is an interesting case as it highlights a rare presentation of zoster: segmental motor paresis that recovered fully with resolution of the rash. It shows the importance of recognizing motor neuropathy as a complication of shingles as it has a very good prognosis with most patients regaining full motor function of the affected limb with treatment.

    Care of an acutely ill parturient is particularly difficult when we have to balance the needs of both mother and the fetus to survive. The literature suggests there should be emphasis on stabilising the mother's condition. In dealing with metabolic acidosis, however, we believe delivering the baby early might not only relieve the threat of the acidosis on the mother, it may be the only way to deliver a live baby. We report two parturient women with severe metabolic acidosis which was considerably reduced very soon after the delivery and how our timely delivery resulted in the birth of two neurologically intact babies.

    Twelve patients with Shy-Drager syndrome (SDS) presenting symptoms of multiple nervous system atrophy and orthostatic hypotension were examined for laryngeal movement disorders and vocal impairment in speech. Vocal fold abductor paresis was found in 11 patients and was bilateral in 10. Speech task performance was recorded in SDS patients, Parkinson patients and age- and sex-matched controls. Trained listeners with inter-rated reliability greater than or equal to .85 judged each recording on 20 attributes while blind to speaker identity. SDS patients had a breathy and strained voice quality, reduced loudness, monopitch and monoloudness, imprecise consonants, variations in rate and rate-slowing, suggesting a flaccid type of dysarthria. In comparison with Parkinson patients, SDS patients had excess vocal hoarseness, intermittent glottal fry and a slow and deliberate speaking rate. Orthostatic hypotension, laryngeal stridor, hoarseness, intermittent glottal fry and slow speech rate were found to be discriminating symptoms of SDS. PMID:6824289

    Thirteen Israeli Friesian cows (3.71 average calvings) in the second or later lactation, fed a daily diet containing 90 g of Ca and 50 g of P, were injected once intramuscularly with 700 micrograms 1 alpha-hydroxy-vitamin D3 in order to investigate its placental transfer and its subsequent metabolism in the neonate. The injection of the vitamin 96 to 24 h before calving slightly increased plasma Ca at parturition, whereas uninjected controls displayed a prominent hypo-calcemia. On the 10th and 20th d after calving, difference in the plasma Ca concentration of the two groups was not significant. At parturition, plasma parathyroid hormone concentration was significantly higher and plasma 1,25-dihydroxyvitamin D lower in the control than in the treated cows. At parturition the plasma concentrations of Ca, parathyroid hormone, hydroxyproline, and 24,25-hydroxyvitamin D were higher in the calves than in their dams. Plasma concentrations of 25-hydroxyvitamin D were markedly higher and 1,25-hydroxyvitamin D was slightly higher in cows than in their offsprings. PMID:3204189

    Concentration of vitamin D metabolites was determined in the milk of control and 1 alpha-hydroxyvitamin D3-injected (700 micrograms) cows that calved 36 to 43 h after treatment. Milk samples were taken 60 h after calving. Concentrations of vitamin D, 25-hydroxyvitamin D, 24,25-dihydroxyvitamin D, and 1,25-dihydroxyvitamin D in milk of the control cows were 372 +/- 24, 264 +/- 68, 68 +/- 26, and 21 +/- 3 ng/L, respectively. Concentrations of vitamin D metabolites in the milk of the treated cows did not differ significantly from those of controls. Concentration of 1 alpha-hydroxyvitamin D3 in milk of treated cows was less than 20 ng/L. In a second experiment, cows were injected twice, at 72-h intervals, with 350 micrograms 1 alpha-hydroxyvitamin D3. Milk was taken 60 h after parturition from cows that calved 37 to 60 h after the second injection. The vitamin D3 equivalence of the milk was 40 +/- 3 IU/L. Results indicate that injection of 700 micrograms 1 alpha-hydroxyvitamin D3 did not affect the concentration of vitamin D metabolites or the vitamin D3 equivalence of milk taken 60 h after calving.

    The obstetric anesthesiologist must consider the risk of spinal-epidural hematoma in patients with thrombocytopenia when choosing to provide neuraxial anesthesia. There are little data exploring this complication in the parturient. In this single-center retrospective study of 20,244 obstetric patients, the incidence of peripartum thrombocytopenia (platelet count <100,000/mm) was 1.8% (368 patients). Of these patients, 69% (256) received neuraxial anesthesia. No neuraxial hematoma occurred in any of our patients. The upper 95% confidence limit for spinal-epidural hematoma in patients who received neuraxial anesthesia with a platelet count of <100,000/mm was 1.2%. PMID:27159067

It is important to avoid excess protein intake and a catabolic state to prevent acidemia. Additionally, it may be wise to avoid anesthetic drugs metabolized by propionyl-CoA carboxylase because use of these drugs may lead to acidosis.

    Background Neuralgic amyotrophy (brachial plexus neuropathy, brachial plexus neuritis, or Parsonage-Turner syndrome) is an uncommon inflammatory condition typically characterized by acute and severe shoulder pain followed by paresis with muscle weakness and atrophy of the upper limb or shoulder girdle. We report an unusual clinical manifestation of neuralgic amyotrophy, namely bilateral phrenic nerve palsy with concomitant laryngeal paresis. Case Report A 55-year-old male presented with orthopnea and aphonia after an episode of bilateral shoulder pain preceded by an upper respiratory tract infection. Spirometry, chest X-ray and videolaryngoscopy revealed bilateral and simultaneous paresis of the diaphragm and the vocal cords. Clinical examination at admission and at the 2-month follow-up did not show upper limb weakness or atrophy, except for a mild atrophy of the right supraspinatus muscle. An electromyography of the upper limb muscles and nerve conduction studies did not reveal signs of denervation. Analysis of the cerebrospinal fluid and an MRI of the neuraxis were unremarkable. After treatment with prednisolone, vocal cord function markedly improved within 8 weeks, whereas paresis of the diaphragm persisted. Conclusion Shoulder pain followed by diaphragmatic paralysis with dyspnea and hoarseness may be a manifestation of neuralgic amyotrophy even if upper limb or shoulder girdle palsies are absent.

    Interscalene brachial plexus block provides effective anesthesia and analgesia for shoulder surgery. One of the disadvantages of this technique is the risk of hemidiaphragmatic paresis, which can occur as a result of phrenic nerve block and can cause a decrease in the pulmonary function, limiting the use of the block in patients with reduced functional residual capacity or a preexisting pulmonary disease. However, it is generally transient and is resolved over the duration of the local anesthetic's action.We present a case of a patient who experienced prolonged hemidiaphragmatic paresis following a continuous interscalene brachial plexus block for the postoperative pain management of shoulder surgery, and suggest a mechanism that may have led to this adverse effect.Nerve injuries associated with peripheral nerve blocks may be caused by several mechanisms. Our findings suggest that perioperative nerve injuries can occur as a result of combined mechanical and chemical injuries. PMID:27310984

    Caring for obese pregnant women presents challenges for all medical professionals. Despite a lack of supporting evidence, expert opinion and international guidelines suggest early labour epidural insertion for obese women. Anecdotally this is not supported by all anaesthetists. This qualitative study explored the experiences of anaesthetists regarding early epidural analgesia in obese parturients, to answer the research question: Are anaesthetists consistent in how they apply early epidural analgesia in obese parturients? Personal in-depth interviews with 42 specialist anaesthetists working in south-east Queensland, Australia, were completed between February and April, 2015. Leximancer™ text analysis software applied a validated algorithm to the data to identify themes and concepts. The major themes were explored by the first author to answer the research question. Three major themes were identified: the demands associated with caring for obese women; concern regarding the anaesthetic technique used in obese women; and the importance of communication with obstetric staff. Disagreement regarding interpretation and application of early epidural analgesia was identified within this group of anaesthetists. These anaesthetists were inconsistent in how they interpreted and applied early epidural analgesia for obese parturients, with some questioning the validity of the practice. The combination of uncertainty, urgency and technical difficulty presented by obese parturients provoked anxiety in these clinicians, particularly the anticipation of unplanned general anaesthesia. Consistent anaesthetic practice could improve the implementation of early epidural analgesia in obese parturients. PMID:27608347

    In order to clarify if a peri-parturient rise of Cryptosporidium parvum oocysts occurs in cows, faecal samples from 42 cows on two farms were collected. These samples were taken during the pre-parturient, the peri-parturient and the post-parturient periods. Two methods were used to detect the oocysts, a nested-PCR coupled with sequencing and a duplex real-time PCR (qPCR) that quantified Cryptosporidium spp. DNA concentration. The qPCR results were adjusted using a hierarchical Bayesian model taking into account within and between run variation. Generalised Estimating Equation models (GEE) were used to determine if peri-parturient cows were at greater risk of being infected than pre- or post-parturient cows. Fourteen dairy cows exhibited a peri-parturient and post-parturient rise in the excretion of Cryptosporidium spp. oocysts, other than the zoonotic C. parvum. The cows in the suckler beef farm were the only ones infected with the zoonotic species C. parvum at calving. Due to the low concentration of oocysts excreted mainly from species other than C. parvum, it would appear unlikely that cows act as a source of infection for their calves or contribute significantly to environmental contamination.

    Background: Establishing an epidural in an agitated laboring woman can be challenging. The ideal pain control technique in such a situation should be effective, fast acting, and short lived. We assessed the efficacy of inhalational methoxyflurane (Penthrox™) analgesia as bridging analgesia for epidural placement. Materials and Methods: Sixty-four laboring women who requested epidural analgesia with pain score of ≥7 enrolled in an observational study, 56 of which completed the study. The parturients were instructed to use the device prior to the onset of uterine contraction pain and to stop at the peak of uterine contraction, repeatedly until epidural has been successfully placed. After each (methoxyflurane inhalation-uterine contraction) cycle, pain, Richmond Agitation Sedation Scale (RASS), nausea and vomiting were evaluated. Maternal and fetal hemodynamics and parturient satisfaction were recorded. Results: The mean baseline pain score was 8.2 ± 1.5 which was reduced to 6.2 ± 2.0 after the first inhalation with a mean difference of 2.0 ± 1.1 (95% confidence interval 1.7-2.3, P < 0.0001), and continued to decrease significantly over the study period (P < 0.0001). The RASS scores continuously improved after each cycle (P < 0.0001). Only 1 parturient from the cohort became lightly sedated (RASS = −1). Two parturients vomited, and no significant changes in maternal hemodynamics or fetal heart rate changes were identified during treatment. 67% of the parturients reported very good or excellent satisfaction with treatment. Conclusion: Penthrox™ provides rapid, robust, and satisfactory therapy to control pain and restlessness during epidural placement in laboring parturient. PMID:26543451

    Ipsilateral hemiparesis is rare after a supratentorial stroke, and the role of reorganization in the motor areas of unaffected hemisphere is important for the rehabilitation of the stroke patients. In this study, we present a patient who had a subclinical remote infarct in the right pons developed ipsilateral hemiparesis and contralateral lower limb paresis caused by a new infarct in the left anterior cerebral artery territory. Our case suggests that the motor areas of the unaffected hemisphere might be reorganized after stroke, which is important for the rehabilitation of stroke patients. PMID:27356659

    We report a 74-year-old woman who presented with recurrent isolated abducens nerve paresis. Cranial magnetic resonance imaging revealed that the right abducens nerve was sandwiched between the right internal carotid artery and a persistent trigeminal artery (PTA) variant, which might have led to neurovascular compression of the abducens nerve, resulting in abducens nerve damage. Normal variants of PTA, which are cerebellar arteries originating from a precavernous portion of the internal carotid artery, must be carefully observed as such variants can potentially cause a neurovascular compression of the abducens nerve.

    Stiff person syndrome is a rare neurologic disorder with an estimated incidence of 1:1000000. The underlying pathophysiology is truncal and proximal limb muscle stiffness resulting from continuous co-contracture of agonist and antagonist muscle groups concomitant with superimposed episodic muscle spasms. Loss of gamma-aminobutyric acid-mediated inhibition creates chronic excitation manifested by tonic agonist-antagonist muscle contraction. To date, only three case reports referred indirectly to the anesthetic management of parturients with Stiff person syndrome. The authors describe their management of a parturient with Stiff person syndrome who underwent urgent cesarean delivery under epidural anesthesia. PMID:27378710

    The periparturient period is one of the most critical periods in the productive life of a dairy cow, and is the period when dairy cows are most susceptible to developing new intramammary infections (IMI) leading to mastitis. Acute phase proteins (APP) such as haptoglobin (Hp), mammary associated serum amyloid A3 (M-SAA3) and C-reactive protein (CRP) have been detected in milk during mastitis but their presence in colostrum and milk in the immediate postpartum period has had limited investigation. The hypothesis was tested that APP are a constituent of colostrum and milk during this period. Enzyme linked immunosorbent assays (ELISAs) were used to determine each APP's concentration in colostrum and milk collected daily from the first to tenth day following calving in 22 Holstein-Friesian dairy cows. Haptoglobin was assessed in individual quarters and composite milk samples while M-SAA3 and CRP concentration were determined in composite milk samples. Change in Hp in relation to the high abundance proteins during the transition from colostrum to milk were evaluated by 1 and 2 dimension electrophoresis and western blot. In 80% of the cows all APPs were detected in colostrum on the first day following parturition at moderately high levels but gradually decreased to minimal values in the milk by the 6th day after calving. The remaining cows (20%) showed different patterns in the daily milk APP concentrations and when an elevated level is detected could reflect the presence of IMI. Demonstration that APP are present in colostrum and milk following parturition but fall to low levels within 4 days means that elevated APP after this time could be biomarkers of post parturient mastitis allowing early intervention to reduce disease on dairy farms.

    A 45 year-old man went to the emergency room due to disease duration of 15 days of insidious onset and progressive course. It began with symmetrical weakness and pain in feet and ankles that extends upward to the knees. Later, this progressed to paraparesis with Creatine phosphokinase levels of 44,270 U/L and respiratory failure that required mechanical ventilation. Electromyography and muscle biopsy of quadriceps were made. The patient responded to corticotherapy in pulses and supporting management. The presentation of ascending paresis suggested the diagnosis of Guillain-Barré syndrome. However, the degree of muscle involvement with rhabdomyolysis explains the neurological damage by itself. The biopsy revealed pathological criteria for necrotizing autoimmune myopathy (NAM), as well as other clinical and laboratory evidence. Patient disease continued and reached criteria for systemic lupus erythematosus (SLE). To our best knowledge, this is the first report of the NAM and SLE association. PMID:23906548

    Radiation-induced tissue damage is caused by ionizing radiation mainly affecting the skin, vascular, neuronal or muscle tissue. Early damages occur within weeks and months while late damages may occur months or even decades after radiation.Radiation-induced paresis of the spine or the trunk muscles with camptocormia or dropped-head syndrome are rare but have already been described as long-term sequelae after treatment of Hodgkin's lymphoma. The differential diagnosis includes limb-girdle muscular dystrophy, fascioscapulohumeral muscular dystrophy (FSHD) or lysosomal storage diseases (e. g. Acid Maltase Deficiency). We present the case of a patient with long lasting diagnostics over many months due to different inconclusive results. PMID:27391986

    New symptom onset of respiratory distress without other cause, and new hemi-diaphragmatic elevation on chest radiography postcardiotomy, are usually adequate for the diagnosis of phrenic nerve paresis. The symptom severity varies (asymptomatic state to severe respiratory failure) depending on the degree of the lesion (paresis vs. paralysis), the laterality (unilateral or bilateral), the age, and the co-morbidity (respiratory, cardiac disease, morbid obesity, etc). Surgical treatment (hemi-diaphragmatic plication) is indicated only in the presence of symptoms. The established surgical treatment is plication of the affected hemidiaphragm which is generally considered safe and effective. Several techniques and approaches are employed for diaphragmatic plication (thoracotomy, video-assisted thoracoscopic surgery, video-assisted mini-thoracotomy, laparoscopic surgery). The timing of surgery depends on the severity and the progression of symptoms. In infants and young children with postcardiotomy phrenic nerve paresis the clinical status is usually severe (failure to wean from mechanical ventilation), and early plication is indicated. Adults with postcardiotomy phrenic nerve paresis usually suffer from chronic dyspnoea, and, in the absence of respiratory distress, conservative treatment is recommended for 6 months -2 years, since improvement is often observed. Nevertheless, earlier surgical treatment may be indicated in non-resolving respiratory failure. We present early (25th day postcardiotomy) right hemi-diaphragm plication, through a video assisted mini-thoracotomy in a high risk patient with postcardiotomy phrenic nerve paresis and respiratory distress. Early surgery with minimal surgical trauma, short operative time, minimal blood loss and postoperative pain, led to fast rehabilitation and avoidance of prolonged hospitalization complications. The relevant literature is discussed. PMID:23304442

    In order to optimize anesthetic management and avoid adverse maternal and fetal outcomes, a clear understanding of the changes in cardiovascular physiology that occur during pregnancy is paramount. The effects of normal gestation on the cardiovascular system are particularly significant in a parturient with cardiac valvular pathology. We present a case of a 27-year-old G2P0 at 37 weeks with a past medical history of diabetes, macrosomia, congenital bicuspid aortic valve with severe stenosis (valve area 0.7 cm2) who was scheduled for elective C-section. A multidisciplinary discussion involving cardiologists, cardiac surgeons, obstetric surgeons, neonatal intensivists, perfusion staff, anesthesiologists, and nursing staff was held to formulate a plan for the perioperative management of this parturient. Also, contingency plans were formulated and discussed with the care providers, in the event of acute decompensation of the mother and baby and possible need for emergency aortic valvuloplasty and/or aortic valve replacement.

    The prevalence of Chlamydia trachomatis infection in Southern Europe is poorly understood and its identification is essential for the design of appropriate prevention policies. The prevalence of C. trachomatis in 2011-2014 was determined through polymerase chain reaction in urine samples from 11,687 unselected parturient women from the Basque Country, Spain (San Sebastián area). The overall age-adjusted prevalence was 1.0 % (95 % CI 0.8-1.2). The prevalence of infection in women younger than 25 years was 6.4 % and decreased substantially with increasing age: 2.0 % in 25-29 year-olds and 0.5 % in older women (P < 0.001). The prevalence was higher in parturient of foreign origin (1.9 %, 95 % CI 1.3-2.5) than in Spanish parturients (0.8 %, 95 % CI 0.6-1.0), (P < 0.001). The results of this study support the need to screen young women as part of antenatal care in Spain. PMID:27247863

    Conversion paresis is the presence of unexplained weakness without detectable neuropathology that is not feigned. To examine the 'abnormal preparation' and 'disrupted execution' hypotheses proposed to explain the movement deficits in conversion paresis, electroencephalographic, electromyographic and kinematic measures were recorded during motor preparation and execution. Six patients with unilateral upper limb conversion weakness, 24 participants feigning weakness and 12 control participants performed a 2-choice precued reaction time task. Precues provided advance information about the responding hand or finger. Patients and feigners demonstrated similar diminished force, longer movement time and extended duration of muscle activity in their symptomatic limb. Patients showed significantly suppressed contingent negative variation (CNV) amplitudes, but only when the symptomatic limb was precued. Despite the similarity in performance measures, this CNV suppression was not seen in feigners. Diminished CNV for symptomatic hand precues may reflect engagement of an inhibitory mechanism suppressing cortical activity related to preparatory processes. PMID:25951783

    A 16-yr-old female blue and gold macaw (Ara ararauna) was presented with an acute history of lethargy, inappetance, ataxia, and paralysis. The bird had rapidly progressed from a normal state to complete inability to perch or ambulate within a 48-hr period. Neurologic examination revealed bilateral hind limb paresis with upper motor neuron signs present in both legs and the vent. Radiographs identified multiple nodular soft-tissue opacities within the cranial coelomic cavity and a single nodule superimposed with the thoracic spine. The bird was euthanized and submitted for necropsy, which revealed a primary pulmonary adenocarcinoma with multiple sites of osseous metastasis, including the vertebrae, and subsequent spinal cord compression. This is the first report of pulmonary adenocarcinoma in this species, although reports of similar tumors in other psittacines have been published. This report, along with others previously published, suggests that vertebral metastasis of primary pulmonary tumors may be more common in psittacine species than previously recognized and, as such, should be considered as a differential diagnosis in psittacine birds exhibiting signs of neurologic dysfunction attributed to a spinal cord lesion.

    An investigation was made of the effect (lambda) equals 0.63 micrometers diode laser radiation with the energy density of 0.6 to 0.8 J cm-2 on parturients affected by nipples' rhagades. In our experiments, we determined the content of prolactin (PRL), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and of progesterone (P) in the parturients' blood serum. It was found that laser radiation produced an insignificant effect on the prolactic (PRL) content in parturients with the normal lactation level. On the contrary, it produced a stimulating effect on the PRL level in parturients with hypogalactia. Possibly, laser radiation promoted the decrease in the FSH level in the parturients' blood serum. It was also found that this laser radiation produced an insignificant effect on the levels of LH, estradiol (E2), and of progesterone. Women subsequently affected by mastitis exhibited a significantly higher PRL level in their blood serum, as compared with women of the control group.

    PubMed Central

    Ghodki, Poonam Sachin; Singh, Noopur Dasmit

    2016-01-01

    Background and Aims: We compared interscalene brachial plexus block (ISBPB) using peripheral nerve stimulation (PNS) and ultrasound (US) techniques. The primary outcomes were the incidence of hemidiaphragmatic paresis (HDP) and the duration of the block. Secondary outcomes were the block success rate, time to conduct the block, onset of sensory block, and dermatomal spread, postoperative pain by Numeric Rating Scale (NRS), duration of postoperative analgesia and incidence of complications. Material and Methods: We conducted a prospective, randomized, and observer-blinded study in 60 patients undergoing shoulder arthroscopy under block plus general anesthesia. ISBPB was performed with 10 ml of 0.5% bupivacaine using either PNS (Group PNS, n = 30) or US (Group US, n = 30). Hemidiaphragmatic function, the primary outcome, was assessed by ultrasonographic evaluation of diaphragmatic movement and pulmonary function tests using a bedside spirometer (forced vital capacity, forced expiratory volume in 1 s and peak expiratory flow rate). General anesthesia was administered to all the patients for surgery. P < 0.05 test was considered to be statistically significant. Results: Twelve patients in Group PNS had HDP and none in Group US (P < 0.0001). PFTs were also significantly reduced in Group PNS (P < 0.0001). The time to conduct the block and sensory onset time both were less in Group US (P < 0.05). The groups did not differ in block success rate, duration of analgesia, and NRS. Other complications like incidence of Horner's syndrome and vascular puncture were comparable in both the groups. Conclusions: PNS guided ISBPB with 10 ml of 0.5% bupivacaine is associated with a higher incidence of HDP as compared to US guided ISBPB. There is no significant difference in quality or duration of analgesia in the two groups.

    In the present work ketamine was used as anesthetic during the labor in order to evaluate the effect of this anesthetic on the binominal fetus-mother. Two groups of parturients and their fetuses, were studied: 1) The experimental group, with 22 parturients and their fetuses submitted to ketamine anesthesia during the labord, and 2) The control group, with 20 parturients and their fetuses without any analgesic treatment during the labor. In 20 cases of the experimental group the anesthetic was injected during the delivery labor and the other two just before it. It were evaluated in the mother's blood the biochemical parameters of the acid-base balance and others collateral effects of the anesthesia; on the fetus's side the same parameters also and the cardiac frequency. The newborn were evaluated by Apgar Score during the first and fifth minutes of life. The incidence of the spontaneous delivery in the experimental group, was 78%; in 22% of these patients the forceps of relief was used. In 22 cases in which Ketamine was applied it were observed, the following events: elevation of the blood pressure (50%), perineum rigidness (18%), dreams and or hallucinations (18%), increase of the cardiac frequency (9%), apneia (4%) and nausea (4%). It was also observed an increase of uterine tonus an abolishment of abdominal press during the delivery labor, studied through the uterine electromyography register. It was noted after the Ketamine application a fall in the pH of the maternal peripherical venous blood, fetal skull blood and the pH of the blood of the umbilical vein. 22% of the newborns, from the experimental group, presented a depression in the first minute of life (Apgar less than or equals to 6). The pCO2 values in the blood of the umbilical artery were higher in the experimental group than in the control one. PMID:1241148

    Impetigo herpetiformis (IH), or generalized pustular psoriasis of pregnancy, is an exceedingly rare, generalized pustular skin eruption occurring during pregnancy associated with hypovolemia, sepsis, hypocalcemia, and airway edema. Fetal outcomes are generally poor, and parturients with IH may present with emergent indications for cesarean delivery due to placental insufficiency. We present a case of IH in a 19-year-old G1P0 who underwent successful general anesthesia for cesarean delivery. Her case highlights the anesthetic implications for patients afflicted with this rare disease, including perioperative pain management, airway concerns, considerations for neuraxial anesthesia, and monitoring challenges.

    Stroke is highly prevalent and a leading cause of serious, long-term disability among American adults. Impaired movement (i.e. paresis) of the stroke-affected arm is a major contributor to post-stroke disability, yet the mechanisms of upper extremity motor recovery are poorly understood, particularly in severely impaired patients who lack hand function. To address this problem, we examined the functional relevance of the contralesional hemisphere in paretic arm motor performance in individuals with severe arm paresis. Twelve individuals with severe stroke-induced arm paresis (Upper Extremity Fugl-Meyer Assessment=17.1 ± 8.5; maximum score=66) participated in the study. Participants performed a reaching response time task with their paretic arm. At varying time intervals following a 'Go' cue, a pair of transcranial magnetic stimulation (TMS) pulses were delivered to contralesional hemisphere primary motor (M1) or dorsal pre-motor cortex (PMd) to momentarily disrupt the pattern of neural firing. Response time components and hand-path characteristics were compared across the 2 sites for trials with and without TMS disruption. There was no significant effect of TMS disruption on overall Response time or Reaction time, but Movement time was significantly longer (i.e. slower) with disruption of the contralesional hemisphere (p=0.015), regardless of which area was stimulated. Peak hand-path velocity and hand-path smoothness were also significantly lower (p=0.005 and p<0.0001, respectively) with TMS disruption of the contralesional hemisphere. The data from this study provide evidence supporting a functionally relevant role of contralesional hemisphere motor areas in paretic arm reaching movements in individuals with severe post-stroke arm impairment.

    Increasing rates of obesity in western populations present management difficulties for clinicians caring for obese pregnant women. Various governing bodies have published clinical guidelines for the care of obese parturients. These guidelines refer to two components of anaesthetic care: anaesthetic consultation in the antenatal period for women with a body mass index (BMI) ≥ 40 kg/m2 and the provision of early epidural analgesia in labour. These recommendations are based on the increased incidence of obstetric complications and the predicted risks and difficulties in providing anaesthetic care. The concept behind early epidural analgesia is logical-site the epidural early, use it for surgical anaesthesia and avoid general anaesthesia if surgery is required. Experts support this recommendation, but there is weak supporting evidence. It is known that the management of labour epidurals in obese women is complicated and that women with extreme obesity require higher rates of general anaesthesia. Anecdotally, anaesthetists view and apply the early epidural recommendation inconsistently and the acceptability of early epidural analgesia to pregnant women is variable. In this topic review, we critically appraise these two practice recommendations. The elements required for effective implementation in multidisciplinary maternity care are considered. We identify gaps in the current literature and suggest areas for future research. While prospective cohort studies addressing epidural extension ('top-up') in obese parturients would help inform practice, audit of local practice may better answer the question "is early epidural analgesia beneficial to obese women in my practice?".

    In this retrospective study, we describe the anesthetic management and its implications in parturients with chronic kidney disease (CKD; n = 9), who underwent elective caesarean delivery. Nine parturients with CKD of various etiologies, who underwent elective Caesarean delivery, were included in this study. Spinal anest-hesia was administered in all parturients with normal coagulation profile through a 25-gauze spinal needle (Quincke) with 0.5% (H) bupivacaine in L2-3 space and T6 level was achieved. Hemodynamics and side effects such as nausea, vomiting, headache, and backache were record. The mean age was 28.22 ± 4.43 years. The mean levels of serum creatinine and serum potassium were 2.78 ± 1.29 mg/dl and 4.11 ± 0.46 meq/l, respectively. Mean baseline values of systolic blood pressure, diastolic blood pressure, and pulse rate were higher which decreased after spinal anesthesia. However, the incidence of hypotension, which required mephentermine treatment, was 11.1%. One patient had symptoms of nausea and vomiting/dizziness at the time of hypotension, which disappeared after treatment with 5 mg of intravenous mephentermine. Baseline value of PR remained high throughout the operation. Parturients with CKD with normal coagulation profile remained hemodynamically stable under spinal anesthesia with minimal side effects. However, a large number of studies are required to determine the safety of spinal anesthesia in this setting. PMID:24574626

    Lemierre's syndrome is characterized by anaerobic septicemia, internal jugular vein thrombosis, and septic emboli associated with infections of the head and neck. We describe an unusual and clinically confusing case of a young woman with an acute paresis of the abducens nerve and partial paresis of the right oculomotor nerve. After an extensive imaging diagnostic procedure, we also documented a peritonsillar abscess and various types of thromboses in intracranial and extracranial veins. Furthermore, we found brain and lung abscesses, which led us to establish the diagnosis of Lemierre's syndrome. Despite intensive anti-coagulation and antibiotic therapy, the patient developed a mycotic aneurysm in the right internal carotid artery directly adjacent to the previously thrombosed cavernous sinus. In summary, we were able to confirm that Lemierre's syndrome may occur in conjunction with uncharacteristic symptoms. Due to the sometimes confusing clinical symptoms as well as clinical and radiological specialties, we had to work on an interdisciplinary basis to minimize the delay prior to establishing the diagnosis and therapy.

    The study was aimed at assessing whether the peri-parturient period is associated with changes of intracellular and plasma inducible heat shock proteins (Hsp) 72 kDa molecular weight in dairy cows, and to establish possible relationships between Hsp72, metabolic, and immunological parameters subjected to changes around calving. The study was carried out on 35 healthy peri-parturient Holstein cows. Three, two, and one week before the expected calving, and 1, 2, 3, 4, and 5 weeks after calving, body conditions score (BCS) was measured and blood samples were collected to separate plasma and peripheral blood mononuclear cells (PBMC). Concentrations of Hsp72 in PBMC and plasma increased sharply after calving. In the post-calving period, BCS and plasma glucose declined, whereas plasma nonesterified fatty acids (NEFA) and tumor necrosis factor-alpha increased. The proliferative responses of PBMC to lipopolysaccharide (LPS) declined progressively after calving. The percentage of PBMC expressing CD14 receptors and Toll-like receptors (TLR)-4 increased and decreased in the early postpartum period, respectively. Correlation analysis revealed significant positive relationships between Hsp72 and NEFA, and between PBMC proliferation in response to LPS and the percentage of PBMC expressing TLR-4. Conversely, significant negative relationships were found between LPS-triggered proliferation of PBMC and both intracellular and plasma Hsp72. Literature data and changes of metabolic and immunological parameters reported herein authorize a few interpretative hypotheses and encourage further studies aimed at assessing possible cause and effect relationships between changes of PBMC and circulating Hsp72, metabolic, and immune parameters in dairy cows.

Despite being only one of three psychiatrists to win a Nobel Prize, he has faded from public consciousness and his name recognition pales in comparison to his contemporary and fellow Austrian, Sigmund Freud. This paper explores his contributions to the field of biological psychiatry and also touches upon reasons, such as the growing bioethics movement, his controversial affiliation with the Nazi Party, and the evolution of neurosyphilis, that explain why Wagner-Jauregg is not more widely celebrated for his contributions to the field of psychiatry, even though his malarial treatment could be considered the earliest triumph of biological psychiatry over psychoanalysis.

    Postherpetic pseudohernia causes an abdominal bulge as well as an abdominal wall herniation. This disease is one of the neurological complications of herpes zoster and essentially consists of paresis of ipsilateral abdominal muscles. Postherpetic pseudohernia may be mistaken for abdominal wall herniation because it is not well known. We describe two cases presenting an abdominal bulge. The ipsilateral abdominal bulge appeared after recovery from abdominal zoster. Abdominal CT showed no evidence of a herniation or mass. We diagnosed a postherpetic pseudohernia. One of the patients recovered spontaneously 4 months after the onset, and the other partially recovered after 2 months. This disease can be expected to disappear spontaneously, unlike abdominal herniation requiring surgery. It has been reported that 79.3% of patients eventually recovered spontaneously. For surgeons and general practitioners, it is beneficial to keep this disease in mind when examining a patient presenting an abdominal bulge. PMID:27229900

    Motor involvement in herpes zoster is very infrequent, occurring in 3%-5% of cases, and it is caused by extension of the inflammatory process to the anterior horn motor neurons, with the subsequent development of segmental motor paralysis. The authors report a 37-yr-old woman with history of paresis in both lower limbs secondary to spinal cord atrophy associated with Vogt-Koyanagi-Harada disease and immunosuppression caused by chronic corticosteroid and azathioprine treatment of ulcerative colitis, who developed worsening of her baseline residual muscle strength in the right lower limb shortly after herpes zoster eruption. Electromyography revealed acute denervation in territories corresponding to L3-L4 and moderate widespread axonal polyneuropathy affecting both lower limbs. The patient recovered her baseline muscle strength after this event. To the best of the authors' knowledge, this is the first reported case of herpes zoster motor neuropathy in a patient with a previous motor sequel. PMID:23221673

    Background Low serum ferritin levels signify low iron stores and this could predispose to iron deficiency anemia. Objective To determine the rate and predictors of low serum ferritin levels during the puerperium in Enugu, Southeast Nigeria. Study design A hospital-based prospective longitudinal study involving parturient women who delivered singleton fetuses at term. Venous blood samples were collected to determine the serum ferritin concentration at 48 hours and 6 weeks postpartum. Data analysis involved descriptive and inferential statistics at 95% confidence interval (CI) using Statistical Package for Social Sciences (SPSS) computer software version 20.0. Results Two-hundred and two women who carried singleton pregnancies to term were studied. The mean serum ferritin levels at 48 hours and 6 weeks were 27.82±18.41 µg/L and 36.12±21.53 µg/L, respectively. Forty-eight hours postdelivery, 29.2% had low ferritin levels and this decreased to 12.4% at 6 weeks postpartum. There was a significant positive correlation between the serum ferritin level at 48 hours postdelivery and the serum ferritin level at 6 weeks postpartum (r=0.89, P<0.001). Predictors of the low ferritin level at 6 weeks included age <20 years (odds ratio [OR] =0.70, 95% CI =0.53, 0.93), multiparity (OR =63.7, 95% CI =3.18, 127.5), anemia at 48 hours postpartum (OR =61.7, 95% CI =13.27, 116.6), a low ferritin level at 48 hours (OR =78.1, 95% CI =8.8, 108.3), and intake of antenatal hematinics for <3 months (OR =0.04, 95% CI =0.01, 0.20). Conclusion There was a significant occurrence of low ferritin levels during the puerperium in the study centers, and this was associated mainly with pregnancy and delivery factors. Efforts to improve the iron stores in parturient women could benefit from early booking and compliance with antenatal hematinics and optimizing hemoglobin and iron levels before delivery.

    Anaesthetists may encounter parturients with a spectrum of anatomical and functional abnormalities secondary to spinal dysraphisms, which are among the most common neurodevelopmental anomalies. These range from surgically corrected open dysraphisms to previously undiagnosed closed dysraphisms. Both bony and neural structures may be abnormal. In true bony spina bifida, which occurs in up to 50% of the population, failure of fusion of the vertebral arch is seen and neural structures are normal. Ninety percent of such cases are confined to the sacrum. In open dysraphisms, sensory preservation is variable and may be present even in those with grossly impaired motor function. Both epidural and spinal blockade have been described for labour analgesia and operative anaesthesia in selected cases but higher failure and complication rates are reported. Clinical assessment should be performed on an outpatient basis to assess neurological function, evaluate central nervous system shunts and determine latex allergy status. Magnetic resonance imagining is recommended to clarify anatomical abnormalities and to identify levels at which neuraxial techniques can be performed. Of particular concern when performing neuraxial blockade is the possibility of a low-lying spinal cord or conus medullaris and spinal cord tethering. Previous corrective de-tethering surgery frequently does not result in ascent of the conus and re-tethering may be asymptomatic. Ultrasound is not sufficiently validated at the point of care to reliably detect low-lying cords. Epidurals should be performed at anatomically normal levels but spread of local anaesthetic may be impaired by previous surgery. PMID:26072279

    Rheumatic heart disease is the most common cardiac disease complicating pregnancy in developing countries. Heart disease accounts for 15% pregnancy-related mortality. In the presence of maternal heart disease, the circulatory changes of pregnancy may result in exacerbation of the hemodynamic perturbations due to complex cardiac valvular lesions leading to decompensation or death of mother or fetus. Determining the ideal anesthetic technique for cesarean section in the presence of complex cardiac conditions remains a much debated topic. General anesthesia is associated with a further increase in pulmonary pressure in response to laryngoscopy and intubation along with myocardial depression by anesthetic agents. Neuraxial blockade may lead to decrease in systemic vascular resistance and cardiac output. We report the successful anesthetic management of a parturient suffering from rheumatic heart disease with multivalvular lesions resulting in severe pulmonary hypertension under epidural anesthesia with good maternal and neonatal outcome. Successful management requires vigilant perioperative monitoring and thorough knowledge of the hemodynamics of complex cardiac valvular disease. PMID:27433072

    Amniotic fluid embolism (AFE) is a disorder with a high mortarity rate, because it often causes sudden respiratory failure, circulatory collapse and disseminated intravascular coagulation (DIC). We present a case of AFE in which an obstetric anesthesiologist promptly initiated resuscitation of a parturient and saved her without any sequelae. Her fetus was diagnosed as intrauterine fetal demise on 25th gestational week and vaginal delivery under epidural analgesia was planned. One hundred and five minutes after induction of labor with prostaglandine E1, sudden tetanic convulsion occurred with a loss of consciousness. An obstetric anesthesiologist immediately started to resuscitate her and her consciousness was restored. However, noncoagulable vaginal bleeding followed. As the hemorrhage persisted, AFE was suspected. Anesthesiologists gave effective massive transfusion therapy, and she recovered from coagulopathy. Total blood loss was 5,524 g. This case was diagnosed as AFE with high serum sialyl-Tn antigen and zinc-coproporphyrin. The obstetric anesthesiologists are one of the best groups of physicans for resuscitation because they have skills in managing obstetric emergencies such as AFE. In this case, the crucial points for successful resuscitation were prompt obstetric anesthesiologist involvement and good communications with obstetricians and midwives. PMID:24498777

    Spinal cord stimulation (SCS) is an approved treatment for complex regional pain syndrome and other chronic pain conditions. These devices enable women with chronic pain to maintain relatively normal lives, with some encountering pregnancy. Use of previously implanted SCS systems in pregnant women is considered controversial due to lack of long-term prospective studies evaluating both maternal and fetal safety. Seven patients at a university pain clinic were identified as having SCS implanted before becoming pregnant. Data on these patients before, during, and after labor were collected through chart review and patient interview. Onset of labor varied among the 7 patients (2 preterm and 5 term). Mode of anesthesia for delivery included 4 neuraxial anesthetics, with 3 successfully obtaining an adequate level of anesthesia for delivery. Four general anesthetics were administered for cesarean delivery, one of which included a failed attempt at neuraxial anesthesia. All infants were born healthy. Management approaches and outcomes in our patients, as well as those previously reported are discussed within this article. Definitive conclusions cannot be drawn from this small cohort. We believe that management of a parturient with an implanted SCS requires careful planning between all peripartum physicians. PMID:25899957

    An outbreak of febrile respiratory disease occurred over 11 days among thirteen adults in Nova Scotia, all members of an extended family and their friends. Signs of illness included bradycardia at the same time as fever, palatal petechiae, and rapidly enlarging bilateral pulmonary infiltrates. Ten of the patients had a four-fold rise in antibody to phase-2 Q-fever antigen as determined by complement fixation on acute and 4-week-convalescent serum samples. Six children of the extended family for whom a four-fold titre rise was shown had slight or no disease. Investigations showed that the illness related to having entered the home of four of the patients on 1 of 2 consecutive days. On the first day the family cat, subsequently found to have antibody to Q fever, gave birth to kittens which she nursed in a basket kept inside the entry way. Q fever has been associated with parturient cattle, sheep, and goats but family pets, particularly cats, have not previously been implicated in human illness. PMID:6151054

    Mitochondrial aminoacyl-tRNA synthetases are an important group of disease genes typically underlying either a disorder affecting an isolated tissue or a distinct syndrome. Missense mutations in the mitochondrial seryl-tRNA synthetase gene, SARS2, have been identified in HUPRA syndrome (hyperuricemia, pulmonary hypertension, renal failure in infancy, and alkalosis). We report here a homozygous splicing mutation in SARS2 in a patient with progressive spastic paresis. We show that the mutation leads to diminished levels of the synthetase in patient's fibroblasts. This has a destabilizing effect on the tRNASer(AGY) isoacceptor, but to a lesser degree than in HUPRA syndrome patients. tRNASer(UCN) is largely unaffected in both phenotypes. In conclusion, the level of tRNASer(AGY) instability may be a factor in determining tissue manifestation in patients with SARS2 mutations. This finding exemplifies the sensitivity of the nervous system to partially reduced aminoacylation, which is sufficient in other tissues to maintain respiratory chain function. PMID:27279129

    Hereditary congenital facial paresis (HCFP) belongs to the congenital cranial dysinnervation disorders. HCFP is characterized by the isolated dysfunction of the seventh cranial nerve and can be associated with hearing loss, strabismus, and orofacial anomalies. Möbius syndrome shares facial palsy with HCFP, but is additionally characterized by limited abduction of the eye(s). Genetic heterogeneity has been documented for HCFP as one locus mapped to chromosome 3q21-q22 (HCFP1) and a second to 10q21.3-q22.1 (HCFP2). The only known causative gene for HCFP is HOXB1 (17q21; HCFP3), encoding a homeodomain-containing transcription factor of the HOX gene family, which are master regulators of early developmental processes. The previously reported HOXB1 mutations change arginine 207 to another residue in the homeodomain and alter binding capacity of HOXB1 for transcriptional co-regulators and DNA. We performed whole exome sequencing in HCFP-affected individuals of a large consanguineous Moroccan family. The homozygous nonsense variant c.66C>G/p.(Tyr22*) in HOXB1 was identified in the four patients with HCFP and ear malformations, while healthy family members carried the mutation in the heterozygous state. This is the first disease-associated HOXB1 mutation with a likely loss-of-function effect suggesting that all HOXB1 variants reported so far also have severe impact on activity of this transcriptional regulator. © 2016 Wiley Periodicals, Inc.

    A 38-year-old man visited our hospital because of hemifacial paresis that developed 2 months after being bit by a tick. We diagnosed idiopathic peripheral facial palsy and gave the patient oral prednisolone and valacyclovir. Although the symptoms completely resolved in about 2 weeks, there was a risk of Lyme neuroborreliosis. The patient therefore received doxycycline (100 mg twice daily) and amoxicillin (1,000 mg 3 times daily) for 14 days. Two months later, he had symptoms of meningitis such as headache and fever accompanied by lymphocytic cerebrospinal fluid pleocytosis. Viral meningitis was diagnosed and treated with parenteral acyclovir. The symptoms of meningitis improved. Tests for serum IgG antibodies against borrelia were positive. We gave the patient a diagnosis of Lyme neuroborreliosis. The patient received intravenous ceftriaxone and had no relapse. It is a rare for meningitis to develop in a patient with cranial neuropathy who received doxycycline. Lyme neuroborreliosis is a rare disease in Japan. Care should therefore be exercised in the diagnosis of Lyme neuroborreliosis and evaluation of the response to treatment. PMID:27356734

    Delayed lesions of the femoral or sciatic nerve are a rare complication after total hip arthroplasty. Several cases in association with cement edges, scar tissue, broken cerclages, deep hematoma, or reinforcement rings have been published. We report about a 62-year-old female who developed a pure motor paresis of the quadriceps muscle 2 weeks after total hip arthroplasty. After electrophysiological evaluation had revealed an isolated femoral nerve lesion, revision of the femoral nerve was performed. During operative revision no pathologic findings could be seen. One week later the patient developed paralysis of the left wrist and finger extensors after using crutches. Electrophysiological evaluation revealed several nerve conduction blocks in physiological entrapments and the diagnosis of hereditary neuropathy with liability to pressure palsies (HNPP) was established. Hereditary neuropathy with liability to pressure palsies (HNPP) is a rare disease with increased vulnerability of the peripheral nerve system with mostly reversible sensorimotor deficits. It should be taken into consideration in cases of atypical findings of compression syndromes of peripheral nerves or delayed neuropathy, e. g., after total hip arthroplasty. PMID:15083272

    Abstract To investigate the risk of chronic low back pain (LBP) in parturients undergoing cesarean delivery (CD) with neuraxial anesthesia (NA). LBP is common during pregnancy and also after delivery, but its etiology is poorly understood. Previous studies that investigated the correlation between epidural labor analgesia and chronic low back pain were inconclusive. These studies lacked objective diagnostic criteria for LBP and did not exclude possible confounders. We performed this nationwide population-based retrospective cohort study to explore the relationship between CD with NA and subsequent LBP. From the Taiwan National Health Insurance Research Database (NHIRD), we identified all primiparas who had given birth between January 1, 2000 and December 31, 2013. Using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedure codes, we identified the women who had vaginal delivery (VD) and those who had CD. The mode of anesthesia was ascertained by the NHI codes. Multivariable logistic regression was used to estimate the odds of postpartum LBP in women undergoing CD with NA compared with those having VD. The outcome was a diagnosis of LBP according to the first ICD-9-CM diagnosis code. The patients were observed for 3 years after delivery or until diagnosis of postpartum LBP, withdrawal from the NHI system, death, or December 31, 2013. Of the 61,027 primiparas who underwent delivery during the observation period, 40,057 were eligible for inclusion in the study. Of these women, 27,097 (67.6%) received VD, 8662 (21.6%) received CD with spinal anesthesia, and 4298 (10.7%) received CD with epidural anesthesia (EA). Women who received CD with EA were found to have higher risk of LBP than did women who received VD, with the adjusted OR being 1.26 (95% CI: 1.17–1.34). CD with EA might increase the risk of subsequent chronic LBP. PMID:27100449

    Rats exposed to spaceflight or centrifugation from mid-to late pregnancy undergo either more or fewer labor contractions at birth, respectively, as compared to those in normal Earth gravity (1-g). In this paper, we report the development and validation of a new telemetric method for quantifying intrauterine pressure (IUP) in freely-moving, late pregnant and parturient rats. We plan to utilize this technique for studies of labor in altered gravity, specifically, to ascertain forces of uterine during birth, which we believe may be changed in micro- and hypergravity. The technique we describe yields precise, reliable measures of the forces experienced by rat fetuses during parturition. A small, surgically-implantable telemetric pressure sensor was fitted within a fluid-filled balloon. The total volume of the sensor-balloon assembly matched that of a full term rat fetus. Real-time videorecordings of sensor-implanted rat dams and non- implanted control dams enabled us to characterize effects of the intrauterine implant on behavioral aspects of parturition. Contraction frequency, duration, pup-to-pup birth intervals and pup-oriented activities of the dams measured during the peri-birth period were unaffected by the sensor implant. These findings establish intrauterine telemetry as a reliable, non-invasive technique for quantifying intrauterine pressures associated with parturition on Earth and in altered gravity environments. This new technology, readily amenable to spaceflight and centrifugation platforms, will enable us to answer key questions regarding the role of altered labor frequency labor in the adaptation of newborn mammals to hypo- and hypergravity.

    An investigation on the occurrence of peri-parturient rise in trichostrongylid nematode egg output in breeding ewes was carried out on a Ranch in the semi-arid area of Kajiado District in Kenya during the period May 1999-April 2000. During the study, 20 ewes randomly selected from the breeding stock and 20 un-mated female yearlings were monitored for faecal strongyle egg output every 3 weeks. A significant peri-parturient rise in faecal egg output occurred at around the time of lambing and throughout the lactation period in the mated ewes, but not in the un-mated yearlings. The occurrence of peri-parturient rise in breeding ewes towards the end of the dry season and at the onset of the short rains was enhanced by the resumption of development of hypobiotic larvae. Self-cure occurred in the un-mated yearlings in September 1999 during the dry season and in November-December 1999 during the wet season, but was less obvious in the pregnant and lactating ewes. The peri-parturient ewes contributed to higher pasture contamination at a time when highly susceptible lambs were grazing alongside. Therefore, the control of gastrointestinal nematode parasites in ewes in this area should aim at reducing the effects of this phenomenon through treatment of ewes about 2-3 weeks to lambing and during lactation.

    AIM To investigate the influence of gestational diabetes mellitus (GDM) on the kinetic disposition and transplacental and amniotic fluid distribution of metoprolol and its metabolites O-desmethylmetoproloic acid and α-hydroxymetoprolol stereoisomers in hypertensive parturients receiving a single dose of the racemic drug. METHODS The study was conducted on hypertensive parturients with well-controlled GDM (n = 11) and non-diabetic hypertensive parturients (n = 24), all receiving a single 100 mg oral dose of racemic metoprolol tartrate before delivery. Serial maternal blood samples (0–24 h) and umbilical blood and amniotic fluid samples were collected for the quantitation of metoprolol and its metabolite stereoisomers using LC-MS/MS or fluorescence detection. RESULTS The kinetic disposition of metoprolol and its metabolites was stereoselective in the diabetic and control groups. Well-controlled GDM prolonged tmax for both enantiomers of metoprolol (1.5 vs. 2.5 h R-(+)-MET; 1.5 vs. 2.75 h S-(−)-MET) and O-desmethylmetoproloic acid (2.0 vs. 3.5 h R-(+)-AOMD; 2.0 vs. 3.0 h S-(−)-OAMD), and for the four stereoisomers of α-hydroxymetoprolol (2.0 vs. 3.0 h for 1′S,2R-, 1′R,2R- and 1′R,2S-OHM; 2.0 vs. 3.5 h for 1′S,2S-OHM) and reduced the transplacental distribution of 1′S,2S-, 1′R,2R-, and 1′R,2S-OHM by approximately 20%. CONCLUSIONS The kinetic disposition of metoprolol was enantioselective, with plasma accumulation of the S-(−)-MET eutomer. Well-controlled GDM prolonged the tmax of metoprolol and O-desmethylmetoproloic acid enantiomers and the α-hydroxymetoprolol stereoisomers and reduced by about 20% the transplacental distribution of 1′S,2S-, 1′R,2R-, and 1′R,2S-OHM. Thus, well-controlled GDM did not change the activity of CYP2D6 and CYP3A involved in metoprolol metabolism. PMID:25291152

    A 26-year-old parturient with Eisenmenger's syndrome and complete atrioventricular block was presented for emergency Cesarean section due to preterm labor. Ventricular tachycardia (VT), which progressed to ventricular fibrillation (VF), started immediately after the incision. Cardiopulmonary resuscitation with electric shocks was given by anesthesiologists while the obstetrician delivered the baby between the shocks. A cardiac surgeon was ready for extracorporeal membrane oxygenation institution in case of emergency but spontaneous circulation of the patient returned after the 3rd shock and the delivery of the baby. The newborn's Apgar score was 4 at 1 minute and 8 at 5 minutes. An implantable cardioverter-defibrillator was inserted before the discharge because the patient had recurrent episodes of VT and VF postoperatively. PMID:26634088

    Background: Gabapentin is effective for treating different types of headache including post-dural puncture headache (PDPH), also used for prophylaxis against migraine. We studied the effect of pre-operative administration of gabapentin on the characteristics of PDPH in parturients undergoing cesarean section (CS) under spinal anesthesia. Materials and Methods: Women undergoing elective cesarean section under spinal anesthesia were randomized to receive preoperative gabapentin 600 mg or placebo. Spinal anesthesia was achieved with 12.5 mg hyperbaric bupivacaine plus 25 μg fentanyl. Babies were followed up by Apgar scores, umbilical artery blood gases, breastfeeding difficulties, and need for NICU admission. The mothers were followed up for any side-effects of gabapentin for 24 h. Patients with PDPH were re-admitted and onset and duration of the headache were reported and severity was assessed using a visual analog scale (VAS) for 4 days from diagnosis. Paracetamol with caffeine and diclofenac were given for treatment, and the doses were adjusted according to VAS; also number of doses given for each group was recorded. Results: Eighty eight patients were randomized, and 2 were excluded. The incidence of headache and co-existing symptoms were similar in both groups. The onset of headache was significantly delayed in gabapentin group (P < 0.05). Also, severity and duration of headache were significantly less in gabapentin group (P < 0.05). The incidence of sedation was more in gabapentin group 11 (26.19%) versus placebo group 3 (6.81%). Neonatal outcomes were statistically insignificant between both groups. Conclusion: Pre-operative administration of gabapentin has no effect on incidence of (PDPH) but delays its onset and reduces its severity and duration in parturients undergoing cesarean section with spinal anesthesia without significant adverse effects on the mother or the baby.

    Background: Malaria is preventable but has contributed significantly to maternal morbidity and mortality in our environment. Malaria parasitaemia during pregnancy is mostly asymptomatic, untreated but with complications. Aim: A follow-up study aimed at determining plasmodium falciparum parasitaemia and associated complications among booked parturient who had intermittent preventive treatment with sulfadoxine-pyrimethamine (SP) compared with another study among unbooked parturients who did not take SP for intermittent preventive treatment in pregnancy (IPTp). Materials and Methods: This study was conducted in the labour ward complex of Federal Teaching Hospital, Abakaliki from March to May 2012. Five hundred booked parturients at term that received two doses of SP were consecutively recruited. A structured data collection sheet was administered to each parturient. Thick and thin blood films were prepared for quantification and speciation of parasitaemia, respectively. The haemoglobin concentration and birth weights were determined. Analysis was done with the Statistical Package for the Social Sciences (SPSS) software with level of significance at P value < 0.05. Results: The prevalence of malaria parasitaemia in the study was 59.6%. The mean age of parturients was 28.7 (5.5). The highest prevalence of malaria parasitaemia, 92% was found among the parturients aged ≤19 years. The association between age and parasitaemia was significant (x2 = 16.496, P = 0.000). The median parity was 1.0 (3.0). The highest prevalence of asymptomatic parasitaemia, 65.5% was noted among the nulliparous parturients. The association between parity and parasitaemia was significant (x2 = 11.551, P = 0.003). Majority of the parturients were of high social class. Those of the lowest social class (class 5) had the highest prevalence (80%) of parasitaemia. The association between social class and parasitaemia was significant (x2 = 9.131, P = 0.003). Prevalence of anaemia in the study was 14

    Botulinum toxin type A (BtxA) injection, constraint-induced movement therapy (CIMT), and robotic therapy (RT) each represent promising approaches to enhance arm motor recovery after stroke. To provide more effective treatment for a 50-year-old man with severe left spastic hemiparesis, we attempted to facilitate CIMT with adaptive approaches to extend the wrist and fingers using RT for 10 consecutive weeks after BtxA injection. This combined treatment resulted in substantial improvements in arm function and the amount of arm use in activities of daily living, and may be effective for stroke patients with severe arm paresis. However, we were unable to sufficiently prove the efficacy of combined treatment based only on a single case. To fully elucidate the efficacy of the combined approach for patients with severe hemiparesis after stroke, future studies of a larger number of patients are needed. PMID:24880058

    Introduction Labour pain is distressing and it produces undue side effects both to the mother and the baby. The incidence is high in developing countries like India where the awareness about labour analgesia is still lacking. Aim It is to find out the incidence of labour pain and the influence of various described factors on pain with a comparison between patients admitted in a government set up with a private set up in a south Indian semi-urban area. Materials and Methods Two hundred continuous uneventful normal deliveries each in a Government (group G) and a private hospital (group P) were enrolled for the study. The reported pain during labour was noted 6-7 hours after delivery by interacting with the patient. The factors like age of the mother, sex and weight of the baby, literacy, socioeconomic status, the use of oxytocics and analgesia were evaluated. Results The incidence of severe pain was more in group G (43.5%) than group P (12%). There was no analgesic intervention in 68.5% in group G while it was 13.5% (27/200) in group P. Even among these 27 patients who did not receive analgesics, only three parturients reported severe pain. Even administration of analgesics in a Government set up did not decrease pain to a significant extent. There were richer and more literate patients in group P. Booked cases were less in group G. Logistic regression analyses to find out factors which influenced pain in either group was used. Gravida, analgesic intervention and admission in a Govt. hospital influenced the pain experience of the parturient. There was minimal antenatal preparation in both the groups. There were no post partum complications. Conclusion Mothers suffered from labour pain to a significant extent and there is an urgent need for awareness about labour analgesia. Primigravida, admission in a Govt. set up and analgesic interventions were the factors which influenced pain than others. Patients admitted in Govt. hospitals suffered more pain with less analgesic

    This pioneering observational study explored the interaction between subacute stroke inpatients and a rehabilitation robot during upper limb training. 25 stroke survivors (age 55 ± 17 years; time since stroke, 52 ± 21 days) with severe upper limb paresis carried out 16 sessions of robot-assisted shoulder/elbow training (InMotion 2.0, IMT, Inc., MA, USA) combined with standard therapy. The values of 3 patient/robot interaction parameters (a guidance parameter: Stiffness, a velocity-related parameter: Slottime, and Robotic Power) were compared between sessions 1 (S1), 4 (S4), 8 (S8), 12 (S12), and 16 (S16). Pre/post Fugl-Meyer Assessment (FMA) scores were compared in 18 patients. Correlations between interaction parameters and clinical and kinematic outcome measures were evaluated. Slottime decreased at S8 (P = 0.003), while Guidance decreased at S12 (P = 0.008). Robotic Power tended to decrease until S16. FMA scores improved from S1 to S16 (+49%, P = 0.002). Changes in FMA score were correlated with the Stiffness parameter (R = 0.4, P = 0.003). Slottime was correlated with movement velocity. This novel approach demonstrated that a robotic device is a useful and reliable tool for the quantification of interaction parameters. Moreover, changes in these parameters were correlated with clinical and kinematic changes. These results suggested that robot-based recordings can provide new insights into the motor recovery process. PMID:25821804

    Pregnancy induces progressive changes in maternal carbohydrate metabolism. As pregnancy advances insulin resistance and diabetogenic stress due to placental hormones necessitate compensatory increase in insulin secretion. When this compensation is inadequate gestational diabetes develops. 'Gestational diabetes mellitus' (GDM) is defined as carbohydrate intolerance with onset or recognition during pregnancy. Women diagnosed to have GDM are at increased risk of future diabetes predominantly type 2 DM as are their children. Thus GDM offers an important opportunity for the development, testing and implementation of clinical strategies for diabetes prevention. Timely action taken now in screening all pregnant women for glucose intolerance, achieving euglycaemia in them and ensuring adequate nutrition may prevent in all probability, the vicious cycle of transmitting glucose intolerance from one generation to another. Given that diabetic mothers have proportionately larger babies it is likely that vaginal delivery will be more difficult than in the normal population, with a higher rate of instrumentally assisted delivery, episiotomy and conversion to urgent caesarean section. So an indwelling epidural catheter is a better choice for labour analgesia as well to use, should a caesarean delivery become necessary. Diabetes in pregnancy has potential serious adverse effects for both the mother and the neonate. Standardized multidisciplinary care including anaesthetists should be carried out obsessively throughout pregnancy. Diabetes is the most common endocrine disorder of pregnancy. In pregnancy, it has considerable cost and care demands and is associated with increased risks to the health of the mother and the outcome of the pregnancy. However, with careful and appropriate screening, multidisciplinary management and a motivated patient these risks can be minimized. PMID:21189875

    Background Intermittent preventive treatment of malaria for pregnant women (IPTp) is a very important strategy for the control of malaria in pregnancy in malaria-endemic tropical countries, where mosquito bites easily occur during evening outdoor activities. Issues related to provision, cost, and acceptability may affect the use of IPTp in some developing countries. The aim of the study was to assess the uptake and adherence to sulphadoxine-pyrimethamine-based intermittent preventive treatment of malaria during pregnancy and the relationship of IPTp use to pregnancy outcomes in two major obstetric centers in South East Nigeria. Methods This was a prospective descriptive study involving women who received antenatal and delivery services. All recruited women were followed-up from booking until delivery, and statistical analysis was done with Epi Info version 7. Results A total of 516 parturients were studied. The mean gestational age at booking was 21.8±6.9 weeks while the mean number of antenatal visits throughout the pregnancy was 5.5±3.1. The rate of uptake of at least one dose of prescribed IPTp was 72.1% (367/516). Of the 367 who took prescribed IPTp, adherence to second doses of IPTp was 59.7% (219/367), and only 4.9% (18/367) took a third dose. Clinical malaria occurred in 85% (127/149) of women who did not receive IPTp at all compared to 20.5% of those who received at least one dose of IPTp. All those who had clinical malaria despite IPTp had only one dose of IPTp despite booking in the second trimester. Malaria in pregnancy occurred significantly more in women who failed to adhere to subsequent doses of IPTp than in those who adhered (24.6% versus 14.3%, respectively; risk ratio =2.5; 95% confidence interval 2.1, 3.0; P<0.001). Similarly, neonatal malaria occurred significantly more in neonates whose mothers did not receive IPTp compared to those whose mothers received at least one dose of IPTp (7.4% versus 3.4%; risk ratio =1.4; 95% confidence interval 0

    Background: Hypotension induced by combined spinal epidural anesthesia in parturient with hypertensive disorders of pregnancy (HDP) can easily compromise blood supply to vital organs including uteroplacental perfusion and result in fetal distress. The aim of this study was to investigate whether the goal-directed fluid therapy (GDFT) with LiDCOrapid system can improve well-being of both HDP parturient and their babies. Methods: Fifty-two stable HDP parturient scheduled for elective cesarean delivery were recruited. After loading with 10 ml/kg lactated Ringer's solution (LR), parturient were randomized to the GDFT and control group. In the GDFT group, individualized fluid therapy was guided by increase in stroke volume (ΔSV) provided via LiDCOrapid system. The control group received the routine fluid therapy. The primary endpoints included maternal hypotension and the doses of vasopressors administered prior to fetal delivery. The secondary endpoints included umbilical blood gas abnormalities and neonatal adverse events. Results: The severity of HDP was similar between two groups. The total LR infusion (P < 0.01) and urine output (P < 0.05) were higher in the GDFT group than in the control group. Following twice fluid challenge tests, the systolic blood pressure, mean blood pressure, cardiac output and SV in the GDFT group were significantly higher, and the heart rate was lower than in the control group. The incidence of maternal hypotension and doses of phenylephrine used prior to fetal delivery were significantly higher in the control group than in the GDFT group (P < 0.01). There were no differences in the Apgar scores between two groups. In the control group, the mean values of pH in umbilical artery/vein were remarkably decreased (P < 0.05), and the incidences of neonatal hypercapnia and hypoxemia were statistically increased (P < 0.05) than in the GDFT group.

    Anesthetic management of patients with preexisting diseases is challenging and individualized approaches need to be determined based on patients’ complications. We report here a case of ultrasound-guided epidural anesthesia in combination with low-dose ketamine during cesarean delivery on a parturient with severe malformations of the skeletal system and airway problems. The ultrasound-guided epidural anesthesia was performed in the L1–L2 space, followed by an intravenous administration of ketamine (0.5 mg/kg) for sedation and analgesia. Satisfactory anesthesia was provided to the patient and spontaneous ventilation was maintained during the surgery. The mother and the baby were discharged 5 days after surgery, no complications were reported for either of them. Our work demonstrated that an ultrasound-guided epidural anesthesia combined with low-dose ketamine can be used to successfully maintain spontaneous ventilation and provide effective analgesia during surgery and reduce the risk of postoperative anesthesia-related pulmonary infection.

    A 24-year-old woman with Marfan syndrome was scheduled for cesarean section in order to avoid progression of heart failure due to severe mitral regurgitation and aortic dissection during labor. Cesarean section was performed under general anesthesia using remifentanil. Anesthesia was induced and maintained with remifentanil (0.1-0.3 μg x kg(-1) x min(-1)) and continuous administration of propofol (target-controlled infusion, 2-3 ng x ml(-1)). The trachea was intubated without a significant hemodynamic change. The patient's systolic blood pressure was maintained between 90 and 120 mmHg during surgery. Intraoperatively, we conducted a transesophageal echocardiography examination, and no remarkable change was seen in the severity of mitral regurgitation and the size of an ascending aorta. An infant was delivered 6 minutes after anesthesia induction. The Apgar scores were 4 at 1 min, 5 at 5 min and 8 at 10 min. Postoperative course was uneventful. We conclude that remifentanil can be used successfully to manage cesarean section of a parturient with Marfan syndrome associated with heart failure due to severe mitral regurgitation under general anesthesia.

    We report a case of a patient with congenital aortic stenosis previously repaired using the Ross procedure, who presented to our unit for urgent caesarean delivery. Management was complicated by moderate residual cardiac disease and the presence of a suprapubic femoro-femoral crossover graft. Following application of five-lead electrocardiogram and invasive blood pressure monitoring, anaesthesia was induced via combined spinal-epidural with epidural volume extension. A high transverse surgical approach avoided the course of the vascular graft, while further precautions included the immediate availability of vascular surgeons and cell salvage. Our anaesthetic technique was tailored to minimise disruption to cardiovascular function, and in particular to limit regurgitant flow across the pulmonary valve. This case highlights the value of early identification of high-risk parturients and multidisciplinary involvement at delivery. Risk stratification in the patient with grown-up congenital heart disease is based upon timely evaluation of the underlying congenital pathology, surgical history and subsequent functional status.

    To investigate the risk of chronic low back pain (LBP) in parturients undergoing cesarean delivery (CD) with neuraxial anesthesia (NA).LBP is common during pregnancy and also after delivery, but its etiology is poorly understood. Previous studies that investigated the correlation between epidural labor analgesia and chronic low back pain were inconclusive. These studies lacked objective diagnostic criteria for LBP and did not exclude possible confounders. We performed this nationwide population-based retrospective cohort study to explore the relationship between CD with NA and subsequent LBP.From the Taiwan National Health Insurance Research Database (NHIRD), we identified all primiparas who had given birth between January 1, 2000 and December 31, 2013. Using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) procedure codes, we identified the women who had vaginal delivery (VD) and those who had CD. The mode of anesthesia was ascertained by the NHI codes. Multivariable logistic regression was used to estimate the odds of postpartum LBP in women undergoing CD with NA compared with those having VD. The outcome was a diagnosis of LBP according to the first ICD-9-CM diagnosis code. The patients were observed for 3 years after delivery or until diagnosis of postpartum LBP, withdrawal from the NHI system, death, or December 31, 2013.Of the 61,027 primiparas who underwent delivery during the observation period, 40,057 were eligible for inclusion in the study. Of these women, 27,097 (67.6%) received VD, 8662 (21.6%) received CD with spinal anesthesia, and 4298 (10.7%) received CD with epidural anesthesia (EA). Women who received CD with EA were found to have higher risk of LBP than did women who received VD, with the adjusted OR being 1.26 (95% CI: 1.17-1.34).CD with EA might increase the risk of subsequent chronic LBP.

    The aim of the present study was to determine the evidence of post-parturient disorders and backfat loss during lactation in sows raised in tropical areas in relation to their backfat thickness before farrowing and postpartum intravenous supportive treatment. Backfat thickness was measured using A-mode ultrasonography at farrowing and weaning (25.5±1.4 d) in 70 sows. The sows were divided into three groups according to backfat thickness before farrowing, i.e., 15.0 to 20.0 mm (n = 21), 20.5 to 25.0 mm (n = 35), >25.0 mm (n = 14) and were categorized into two groups according to the postpartum supportive treatment, i.e., control (n = 31) and treatment (n = 39). After farrowing, the sows in treatment group received the same medications as in control sows. Furthermore an intravenous supportive treatment with amino acids and vitamins was administered in treatment groups. Rectal temperature and clinical signs of the sows including vaginal discharge, udder problems and appetite were determined at d 0, 1, 2 and 3 of parturition. It was found that, on average, the backfat thickness was 22.4±3.9 mm at farrowing and 19.9±2.9 mm at weaning. The backfat loss and the relative backfat loss during the lactation period were 2.6 mm and 10.6%, respectively. The sows with a backfat of 15.0 to 20.0 mm before farrowing lost less backfat than those with a backfat of 20.5 to 25.0 mm and >25.0 mm (p<0.05). Sows with a backfat of 15.0 to 20.0 mm had a better appetite on d 1 postpartum than sows with a backfat of 20.5 to 25.0 mm (p = 0.020). The percentage of sows losing backfat >10% during lactation were higher in sows with a backfat of >25.0 mm before farrowing (85.7%) than sows with a backfat of 15.0 to 20.0 mm before farrowing (35.0%) (p = 0.008). The percentage of sows with a reduced appetite on d 1 (90.3% vs 71.8%, p = 0.018) and d 2 (61.3% versus 33.3%, p = 0.005) postpartum in the treatment group was lower than the control group. In conclusion, the backfat thickness of sows at

    Falls while walking are frequent in patients with muscular dysfunction resulting from neurological disorders. Falls induce injuries that may lead to deconditioning and disabilities, which further increase the risk of falling. Therefore, an early gait stability index would be useful to evaluate patients in order to prevent the occurrence of future falls. Derived from chaos theory, local dynamic stability (LDS), defined by the maximal Lyapunov exponent, assesses the sensitivity of a dynamic system to small perturbations. LDS has already been used for fall risk prediction in elderly people. The aim of the present study was to provide information to facilitate future researches regarding gait stability in patients with neurological gait disorders. The main objectives were 1) to evaluate the intra-session repeatability of LDS in patients and 2) to assess the discriminative power of LDS to differentiate between healthy individuals and neurological patients. Eighty-three patients with mild to moderate neurological disorders associated with paresis of the lower extremities and 40 healthy controls participated in the study. The participants performed 2×30 s walking wearing a 3D accelerometer attached to the lower back, from which 2×35 steps were extracted. LDS was defined as the average exponential rate of divergence among trajectories in a reconstructed state-space that reflected the gait dynamics. LDS assessed along the medio-lateral axis offered the highest repeatability and discriminative power. Intra-session repeatability (intraclass correlation coefficient between the two repetitions) in the patients was 0.89 and the smallest detectable difference was 16%. LDS was substantially lower in the patients than in the controls (33% relative difference, standardized effect size 2.3). LDS measured in short over-ground walking tests seems sufficiently reliable. LDS exhibits good discriminative power to differentiate fall-prone individuals and opens up the possibility of

    Patients with Klippel-Feil Syndrome (KFS) have congenital fusion of their cervical vertebrae due to a failure in the normal segmentation of the cervical vertebrae during the early weeks of gestation and also have myriad of other associated anomalies. Because of limited neck mobility, airway management in these patients can be a challenge for the anesthesiologist. We describe a unique case in which a dexmedetomidine infusion was used as sedation for an awake fiber-optic intubation in a parturient with Klippel-Feil Syndrome, who presented for elective cesarean delivery. A 36-year-old female, G2P1A0 with KFS (fusion of cervical vertebrae) who had prior cesarean section for breech presentation with difficult airway management was scheduled for repeat cesarean delivery. After obtaining an informed consent, patient was taken in the operating room and non-invasive monitors were applied. Dexmedetomidine infusion was started and after adequate sedation, an awake fiber-optic intubation was performed. General anesthetic was administered after intubation and dexmedetomidine infusion was continued on maintenance dose until extubation. Klippel-Feil Syndrome (KFS) is a rare congenital disorder for which the true incidence is unknown, which makes it even rare to see a parturient with this disease. Patients with KFS usually have other congenital abnormalities as well, sometimes including the whole thoraco-lumbar spine (Type III) precluding the use of neuraxial anesthesia for these patients. Obstetric patients with KFS can present unique challenges in administering anesthesia and analgesia, primarily as it relates to the airway and dexmedetomidine infusion has shown promising result to manage the airway through awake fiberoptic intubation without any adverse effects on mother and fetus.

    Various biochemical markers help to evaluate the state of bone turnover in humans and could be used during the peri-parturient period in dairy cows when calcium (Ca) metabolism changes dramatically. To investigate this, the peri-partum characteristics of serum bone-specific alkaline phosphatase (BAP) and urinary deoxypyridinoline (DPD) were investigated. Both serum BAP activity and urinary DPD concentrations were increased and demonstrated wide variability in younger animals, and these findings were consistent with other bone turnover markers. Around the time of parturition, serum Ca concentration and serum BAP activity in multiparous cows were significantly lower than in primiparous cows, but urinary DPD concentration was unchanged. The use of BAP as a bone formation marker appears to be valuable for evaluating bone remodelling status in cows, but the specificity of the test needs to be confirmed. The DPD/BAP ratio around parturition demonstrated a clear difference in bone turnover status between the two parity groups with multiparous cows demonstrating increased signs of bone resorption compared with primiparous cows, corresponding to the Ca requirement for milk production. In future studies, the applicability of the ratio of bone resorption marker to bone formation marker should be evaluated for bone turnover assessment. PMID:23422881

    Objective To report on the failure rate of spinal catheters placed following inadvertent dural puncture (IDP) compared with re-sited epidural catheters in the obstetric population. Research design and methods Patients who experienced IDP during epidural or combined spinal epidural placement with 17 or 18 gauge Tuohy needles for labor analgesia between 2003 and 2014 were identified using our post-dural puncture headache (PDPH) database. Patients were categorized into two groups: those who had spinal catheters inserted and those who had epidural catheters re-sited. Main outcome measure Failure rate associated with spinal or re-sited epidural catheters (defined as need for repeat block or alternative analgesic modality). Secondary outcomes were incidence of PDPH, need for epidural blood patch (EBP), and adverse events. Results A total of 109 patients were included in the final analysis; 79 ultimately had spinal catheters and 30 ultimately had re-sited epidural catheters. There were no differences between spinal catheters and re-sited epidural catheters in failure rate (22% vs. 13%, P = 0.33), incidence of PDPH (73% vs. 60%, P = 0.24), need for EBP (42% vs. 30%, P = 0.28), number of headache days, or maximum headache scores. There was also no difference in the rate of adverse events including high block levels, hypotension, and fetal bradycardia (9% vs. 7%, P = 1.0) between the two groups. Conclusions There were no differences in failure rates, PDPH outcomes, or adverse events between spinal catheters and re-sited epidural catheters following IDP in parturients receiving labor analgesia. Limitations of the study include its single-center retrospective non-randomized design, and the uneven number of patients in the two groups with a relatively small number in the re-sited epidural catheter group.

    Prolactin, HCG and oestrogen are reported to have a role in regulating serum leptin levels and therefore adiposity in pregnancy. The aim of this study was to determine serum leptin levels during pregnancy in African women, and was conducted in the Antenatal Clinic, King Edward VIII Hospital, Durban, South Africa. Eighty-two obese and non-obese women were studied. Demographic details and anthropometric measurements were recorded, and serum leptin levels determined by radio-immunoassay in all women. Age, parity and gestational age showed a weak correlation with leptin levels. Weight (4=0.6); body mass index (r=0.5), and the circumference of midarm (r=0.4), waist (4-0.6, hip (5=0.5) and thigh correlated positively with leptin values. Serum leptin values in African pregnant women are not dissimilar to that of studies in other racial groups. PMID:12521847

    Bilateral recurrent laryngeal nerve (RLN) injury is rare for benign thyroid lesions (0.2%). After extubation-stridor, respiratory distress, aphonia occurs due to the closure of the glottic aperture necessitating immediate intervention and emergency intubation or tracheostomy. Intra-operative identification and preservation of the RLN minimizes the risk of injury. It is customary to expect RLN problems after thyroid surgery especially if malignancy, big thyroid, distorted anatomical problems and difficult airway that can lead to intubation trauma. Soon after extubating, it is essential to the anesthetist to check the vocal cord movements on phonation and oropharyngeal reflexes competency. But this case is specially mentioned to convey the message that in spite of absence of above mentioned predisposing factors for complications and good recovery profile specific to thyroid, there can be unanticipated airway compromise that if not attended to immediately may cost patient's life. This is a case of postextubation stridor following subtotal thyroidectomy due to bilateral RLN damage and its management. PMID:26417137

    Summary Objective: The objective of this story of case is to describe an uncommon cause of associated peripheral Vestibulopathy to the unilateral auditory loss in aged patient after catheterization of urgency. Story of case: Patient of the masculine sort, 82 years, submitted to the correction of abdominal ragged aneurism of aorta, in the intra-operative suffered heart attack acute from the myocardium needing primary angioplasty. High after hospital it relates to complaint of accented hearing loss to the right and crippling vertigo, without focal neurological signals. To the otorhinolaryngological clinical examination it presented: Test of Weber lateralized for the left, spontaneous nystagmus for the left, marches rocking, has taken normal disbasia and ataxia, index-nose and diadochokinesia, Test of Romberg with oscillation without fall and Fukuda with lateral shunting line for the right. The audiometric examination evidenced deafness to the right and sensorineural loss to the left in sharps, areflexia initial to the right in caloric test e, the computerized tomography of the secular bones and brainstem, presence of metallic connecting rod crossing the right secular bone, from the vein internal jugular vein and bulb jugular vein, crossing the posterior, superior and vestibule semicircular canals, projecting itself in temporal lobe. The radiological diagnoses was traumatic injury for guide to endovascular metallic during catheterization of urgency and the behavior, considering that the patient had not compensated the balance, it was vestibular rehabilitation. Conclusion: Complaints of giddiness in the aged patient must be closely evaluated of its pathological clinical description because the antecedents of illnesses and previous treatments, in general, direct the diagnostic hypotheses however they can bring unexpected alterations.

    Over the past 40 years, the success of organ transplantation has increased such that female solid organ transplant recipients are able to conceive and carry pregnancies successfully to term. Anesthesiologists are faced with the challenge of providing anesthesia care to these high-risk obstetric patients in the peripartum period. Anesthetic considerations include the effects of the physiologic changes of pregnancy on the transplanted organ, graft function in the peripartum period, and the maternal side effects and drug interactions of immunosuppressive agents. These women are at an increased risk of comorbidities and obstetric complications. Anesthetic management should consider the important task of protecting graft function. Optimal care of a woman with a transplanted solid organ involves management by a multidisciplinary team. In this focused review article, we review the anesthetic management of pregnant patients with solid organ transplants of the kidney, liver, heart, or lung. PMID:27285002

    We describe a case of anaphylaxis that occurred in a 33-year-old gravida 1, para 1 term woman scheduled for cesarean delivery for breech presentation. Her past history was unremarkable except for orciprenaline allergy. Spinal anesthesia was performed at L3-4 using 2.5 ml of 0.5% hyperbaric bupivacaine and 0.1 mg morphine. Seven minutes after spinal anesthesia, she complained of hoarseness and difficulty in breathing and 3 minutes later, blood pressure decreased to 76/51 mmHg, and oxygen saturation to 87% with supplemental oxygen. Skin flushing was noted in the face and trunk of the body and anaphylaxis was diagnosed. She was treated with a rapid intravenous infusion and iv administration of phenylephrine (total dose 0.4 mg), ephedrine (total dose 25 mg), hydrocortisone and famotidine. Cesarean section was started 23 minutes after spinal anesthesia when blood pressure and oxygen saturation recovered. A male infant was delivered (18 minutes after the onset of anaphylactic event) with Apgar scores of 2 and 5 at 1 and 5 min, respectively and resuscitated with mask ventilation. Umbilical artery blood gas analysis revealed pH 6.85, base excess -20.3 mmol x l (-1) and lactate 109 mg x dl (-1). The mother was discharged from the hospital on the 6th postoperative day. The baby's electroencephalogram, however, demonstrated a pattern consistent with mild hypoxic-ischemic encephalopathy. Lymphocyte stimulation test revealed that she was allergic to bupivacaine. If maternal hypotension persists, i.m. or i.v. adrenaline should be administered immediately because maternal hypotension and hypoxemia may cause significant fetal morbidity and mortality and prompt cesarean section should be considered.

    We report a case of spinal subdural haematoma with neurological deficit in a 36-yr-old woman following Caesarean section for severe preeclampsia and placental abruption. She had been taking chronic trifluoperazine treatment for depression. Her activated partial thromboplastin time (aPTT) was 49 sec (normal = 26-36) but all other tests of coagulation were normal. Epidural anaesthesia was attempted but, despite a negative test dose, injection of local anaesthetic resulted in a generalized seizure and general anaesthesia was induced. Seventy-two hours after delivery, she was found to have bilateral leg weakness, urinary incontinence, absent rectal sphincter tone and asymmetrical leg reflexes. The diagnosis of spinal haematoma was confirmed by magnetic resonance imaging. She underwent emergency laminectomy and made a full neurological recovery. PMID:8485794

    The objectives of this work were (i) to characterize the pharmacokinetics of cefazolin in pregnant women undergoing elective cesarean delivery and in their neonates; (ii) to assess cefazolin transplacental transmission; (iii) to evaluate the dosing and timing of preoperative, prophylactic administration of cefazolin to pregnant women; and (iv) to investigate the impact of maternal dosing on therapeutic duration and exposure in newborns. Twenty women received 1 g of cefazolin preoperatively. Plasma concentrations of total cefazolin were analyzed from maternal blood samples taken before, during, and after delivery; umbilical cord blood samples obtained at delivery; and neonatal blood samples collected 24 h after birth. The distribution volume of cefazolin was 9.44 liters/h. The values for pre- and postdelivery clearance were 7.18 and 4.12 liters/h, respectively. Computer simulations revealed that the probability of maintaining free cefazolin concentrations in plasma above 8 mg/liter during scheduled caesarean surgery was <50% in the cord blood when cefazolin was administered in doses of <2 g or when it was administered <1 h before delivery. Therapeutic concentrations of cefazolin persisted in neonates >5 h after birth. Cefazolin clearance increases during pregnancy, and larger doses are recommended for surgical prophylaxis in pregnant women to obtain the same antibacterial effect as in nonpregnant patients. Cefazolin has a longer half-life in neonates than in adults. Maternal administration of up to 2 g of cefazolin is effective and produces exposure within clinically approved limits in neonates.

    Preclinical studies using animal models have shown that grey matter plasticity in both perilesional and distant neural networks contributes to behavioural recovery of sensorimotor functions after ischaemic cortical stroke. Whether such morphological changes can be detected after human cortical stroke is not yet known, but this would be essential to better understand post-stroke brain architecture and its impact on recovery. Using serial behavioural and high-resolution magnetic resonance imaging (MRI) measurements, we tracked recovery of dexterous hand function in 28 patients with ischaemic stroke involving the primary sensorimotor cortices. We were able to classify three recovery subgroups (fast, slow, and poor) using response feature analysis of individual recovery curves. To detect areas with significant longitudinal grey matter volume (GMV) change, we performed tensor-based morphometry of MRI data acquired in the subacute phase, i.e. after the stage compromised by acute oedema and inflammation. We found significant GMV expansion in the perilesional premotor cortex, ipsilesional mediodorsal thalamus, and caudate nucleus, and GMV contraction in the contralesional cerebellum. According to an interaction model, patients with fast recovery had more perilesional than subcortical expansion, whereas the contrary was true for patients with impaired recovery. Also, there were significant voxel-wise correlations between motor performance and ipsilesional GMV contraction in the posterior parietal lobes and expansion in dorsolateral prefrontal cortex. In sum, perilesional GMV expansion is associated with successful recovery after cortical stroke, possibly reflecting the restructuring of local cortical networks. Distant changes within the prefrontal-striato-thalamic network are related to impaired recovery, probably indicating higher demands on cognitive control of motor behaviour. PMID:24906703

    Background Neuroanatomical determinants of motor skill recovery after stroke are still poorly understood. Although lesion load onto the corticospinal tract is known to affect recovery, less is known about the effect of lesions to cortical sensorimotor areas. Here, we test the hypothesis that lesions of somatosensory cortices interfere with the capacity to recover motor skills after stroke. Methods Standardized tests of motor skill and somatosensory functions were acquired longitudinally over nine months in 29 patients with stroke to the pre- and postcentral gyrus, including adjacent areas of the frontal, parietal and insular cortices. We derived the recovery trajectories of each patient for five motor subtest using least-squares curve fitting and objective model selection procedures for linear and exponential models. Patients were classified into subgroups based on their motor recovery models. Lesions were mapped onto diffusion weighted imaging scans and normalized into stereotaxic space using cost-function masking. To identify critical neuranatomical regions, voxel-wise subtractions were calculated between subgroup lesion maps. A probabilistic cytoarchitectonic atlas was used to quantify of lesion extent and location. Results Twenty-three patients with moderate to severe initial deficits showed exponential recovery trajectories for motor subtests that relied on precise distal movements. Those that retained a chronic motor deficit had lesions that extended to the center of the somatosensory cortex (area 2) and the intraparietal sulcus (areas hIP1, hIP2). Impaired recovery outcome correlated with lesion extent on this areas and somatosensory performance. The rate of recovery, however, depended on the lesion load onto the primary motor cortex (areas 4a, 4p). Conclusions Our findings support a critical role of uni-and multimodal somatosensory cortices in motor skill recovery. Whereas lesions to these areas influence recovery outcome, lesions to the primary motor cortex affect recovery dynamics. This points to a possible dissociation of neural substrates for different aspects of post-stroke recovery. PMID:22363604

    Ganglion cysts are common benign masses, usually occurring in the hands and feet. This report describes the case of a young female Irish dancer who presented with paresthesia of her foot due to a ganglion in near proximity to the superficial peroneal nerve. Midfoot ganglia in young girls engaged in Irish dance can limit their ability to participate. This pathology requires further epidemiological studies to investigate its prevalence. In the event of failed conservative management, surgical intervention to excise the cyst and decompress the nerve is an effective treatment to facilitate return to dancing. PMID:26045399

    Analytical advancements, especially methods using gas or liquid chromatography tandem mass spectrometry, have allowed more specific and reliable measurement of multiple steroid hormones in the plasma of mares throughout gestation and the periparturient period. Data such as these will form the central focus of this review. The comprehensive analyses possible with liquid chromatography tandem mass spectrometry illuminate the key physiological and developmental transitions that make equine gestation unique. Weeks 6 to 20 encompass endometrial cup formation and equine chorionic gonadotropic secretion that stimulates primary corpora lutea and induces formation of secondary luteal structures. The period is defined by increased progesterone, 17OH-progesterone, and androstenedione secretion, providing substrate feeding the rise in estrone sulfate that can be used as an aid in the diagnosis of pregnancy. The 5α-reduced metabolite of progesterone, dihydroprogesterone (DHP), parallels progesterone secretion during this period at less than half the concentration. After week 12, progesterone declines, but DHP concentrations continue to increase, exceeding progesterone by week 16, thereby defining the luteo-placental shift in pregnane synthesis from ovarian to primarily placental thereafter. The growth of fetal gonads begins around week 14 and is defined by increasing dehydroepiandrosterone, among other androgens, which fuels placental estrogen secretion, functioning as a true fetoplacental unit. Metabolites of DHP (including allopregnanolone) dominate in late gestation, some exceeding DHP by 10-fold near term. However, all major pregnanes decrease from 3 days before foaling, when fetal cortisol is reportedly rising. Though unique, equine pregnancy and parturition share many features in common with those seen in human pregnancy and birth. PMID:27156685

    Malaria is associated with high rates of morbidity and mortality worldwide, particularly in Africa, Southeast Asia and South America. Nonetheless, several cases of malaria have been reported in Western countries involving travelers from endemic areas, though very few involve pregnant women. In this article, we report a case of a young woman born in Sierra Leone who had been living in Italy for two years. She was admitted to our hospital with malaise; worsening of her condition led to Plasmodium falciparum infection diagnosis early during her hospital stay, as well as an urgent cesarean delivery. We briefly discuss the features of malaria in pregnancy, the difficulties associated with early diagnosis, and the possible fetal and maternal implications, and also consider how the disease may affect anesthetic management.

    Mucopolysaccharidosis is genetically determined disease caused by the deficiency of one of the lysosomal enzymes involved in the glycosaminoglycan (GAG) breakdown pathway. This metabolic block leads to the accumulation of GAG in various organs and tissues and affects nerve system, eyes, internal organs and musculoskeletal system. The reviewer of various articles on pubmed showed only one article about epidural anesthesia in patient with type I mucopolysaccharidosis. Our observation allows to consider that epidural anesthesia with ropivacaine is possible and safe in patients with type I mucopolysaccharidosis. PMID:22379910

    In the canine species, the precise mechanisms of pregnancy maintenance and the initiation of parturition are not completely understood. The expression of genes encoding the receptors for estrogen (ERα mRNA) and oxytocin (OTR mRNA) was studied in the endometrium and myometrium during pregnancy and parturition in dogs. Real-time PCR was performed to quantify the levels of ERα mRNA and OTR mRNA in the uterus of bitches during early (up to 20 days of gestation), mid (20 to 40 days) and late pregnancy (41 to 60 days), and parturition (first stage of labor). All tissues expressed ERα and OTR mRNA, and are thus possibly able to respond to eventual estrogen and oxytocin hormonal stimuli. No statistically significant differences in the expression of ERα mRNA were verified in the endometrium and myometrium throughout pregnancy and parturition, but expression of OTR mRNA increased at both parturition and late pregnancy. We concluded that the increase of endometrial and myometrial OTR mRNA expression in dogs is not an event dependent on estrogenic stimulation. Moreover, the contractility response of the canine uterus to oxytocin begins during pregnancy and maintains myometrial activity. The expression of OTR mRNA in canine uterine tissues varied over time, which supports an interpretation that the sensitivity and response to hormone therapy varies during the course of pregnancy and labor. Further studies are needed to elucidate the factors underlying the synthesis of uterine oxytocin receptors and the possible role of ERβ rather than ERα in the uterine tissues during pregnancy and parturition in dogs.

    Meralgia paresthetica is commonly caused by a focal entrapment of lateral femoral cuteneous nerve while it passes the inguinal ligament. Common symptoms are paresthesias and numbness of the upper lateral thigh area. Pregnancy, tight cloths, obesity, position of surgery and the tumor in the retroperitoneal space could be causes of meralgia paresthetica. A 29-year-old female patient underwent an emergency cesarean section under spinal anesthesia without any problems. But two days after surgery, the patient complained numbness and paresthesia in anterolateral thigh area. Various neurological examinations and L-spine MRI images were all normal, but the symptoms persisted for a few days. Then, electromyogram and nerve conduction velocity test of the trunk and both legs were performed. Test results showed left lateral cutaneous nerve injury and meralgia paresthetica was diagnosed. Conservative treatment was implemented and the patient was free of symptoms after 1 month follow-up. PMID:21286469

    Psychiatric disorders may complicate the pregnancy and is one of the causes of maternal and fetal morbidity. We report the case of a patient with severe decompensated schizophrenia during her pregnancy that required prolonged hospitalization in psychiatric ward. The psychiatric status of the patient required the realization of a caesarean section at 36 weeks of amenorrhea. In our case, we decided to perform this cesarean section under general anaesthesia, since regional anaesthesia was not feasible in this patient in a state of uncontrolled agitation. Moreover, general anaesthesia permitted to combine cesarean section with a first session of electroconvulsive therapy, which had been declined during pregnancy. Given the huge amount of antipsychotic agents administered to the patient, we also studied their transplacental transfer and found a very high loxapine concentration in the fetus. Finally, this case raised several important ethical issues related to the management of the mother and her fetus in case of severe psychiatric disorders. PMID:24054003

    Patients presenting with distal weakness can be a diagnostic challenge; the eventual diagnosis often depends upon accurate clinical phenotyping. We present a mother and daughter with a rare form of distal hereditary motor neuropathy type 7 in whom the diagnosis became apparent by initial difficulty in singing, from early vocal cord dysfunction. This rare neuropathy has now been identified in two apparently unrelated families in Wales. This family's clinical presentation is typical of distal hereditary motor neuropathy type 7, and they have the common truncating mutation in the SLC5A7 gene. Advances in genetic analysis of these rare conditions broaden our understanding of their potential molecular mechanisms and may allow more directed therapy. PMID:26786006

    2010-01-01

    Background An elevated plasma glucose concentration has been considered to be a potential risk factor in the pathogenesis of left-displaced abomasums (DA). Therefore the present study was performed to investigate if spontaneous disease (parturient paresis, metritis, ketosis etc) in dairy cows results in elevated concentrations of glucose and cortisol in blood as cortisol is the major regulator of glucose in ruminants. Methods Cortisol, insulin, β-hydroxybutyric acid (BHBA), non esterified fatty acids (NEFA), and serum calcium were analyzed in blood serum and glucose, in whole blood, from 57 spontaneously diseased cows collected at different farms. The cows were grouped according to the disease; parturient paresis, recumbent for other reasons, mastitis, metritis, ketosis, inappetance and others. Results No elevated concentrations of cortisol or glucose were found in cows with metritis and mastitis but both cortisol and glucose were elevated in cows stressed by recumbency. Cows with ketonemia (BHBA > 1.5 mmol/l) did not have low concentration of glucose in blood but significantly low levels of cortisol. Some of these cows even had cortisol concentrations below the detection limit of the analysing method (< 14 nmol/l). Conclusions The study gives patho-physiological support to the treatment strategies of ketosis, recommending glucocorticoids, insulin etc. However further studies of this problem are needed to understand why cows with ketosis have low levels of cortisol and normal levels of glucose. To what extent elevated cortisol and glucose levels in hypocalcemic and recumbent cows are involved in the ethiology and /or the pathogenesis of DA also will need further research. PMID:20487518

    Risk factors associated with the development of clinical mastitis (CM) in multiparous cows, defined as detection of abnormalities in the milk by farm staff in the 30days before and 90days after calving were studied using a retrospective longitudinal cohort study of 18,162 cows on 30 South Island commercial New Zealand dairy farms. Risk factors studied included age, breed, length of dry period, farm, herd size, yield and individual somatic cell count (ISCC) status 30-60days before the end of the previous lactation, rainfall at calving and number calving on the same day. A modified Cox Proportional hazards model with time varying effects for breed, age, length of dry period and ISCC was used to identify which factors were significantly associated with an increased hazard of CM after calving Rainfall at calving >10mm increased the hazard ratio (HR) by 1.14 (95%CI=1.01-1.30) for 30days before to 90days after calving. Milk production >1.5kgMS/cow/day in the 30-60days before the end of lactation increased the HR for CM by 1.36 (95%CI=1.21-1.52) for the same period. The effects of breed, age, length of dry period and ISCC 30-60days before the end of lactation varied with time around calving. The HR decreased as the proportion of Friesian genetics decreased. Compared to animals >75% Friesian the HR for animals that were <25% Friesian was 0.50 (95%CI=0.26-0.99) in the 30days before calving, 0.81 (95%CI=0.60-1.08) in the 20days after calving and 0.28 (95%CI=0.18-0.62) from 21 to 90days after calving. HR increased with age, with the largest effect seen 21-90days after calving. Compared to cows <4 years of age, cows that were 4-8 years of age had a HR of 2.18 (95%CI=1.71-2.76) and those >8 years old had a HR of 4.09 (95%CI=3.06-5.46) for this period. Dry periods >112days had a HR of 1.46 (95%CI=1.24-1.73) in the 20days after calving but a decreased HR (0.73, 95%CI=0.57-0.94) 21-90days after calving. Cows with ISCC >150,000 cells/ml 30-60days before the end of lactation had a HR of 1.60, (95%CI=1.39-1.84) 0-20days after calving and 1.96 (95%CI=1.67-2.27) 21-90days after calving. Neither number of animals calving per day, nor herd size was associated with an increased hazard of CM and there was a significant difference in the hazard across farms. PMID:27094143

    A 29-year-old woman at 34 weeks' gestation with uncontrolled hyperthyroidism and thyrotoxic heart disease was admitted to urgency Cesarean section. After preoperative sedation and good communication, low-dose spinal anesthesia (7.5 mg 0.5 % bupivacaine) combined with epidural anesthesia (6 ml 2 % lidocaine) was performed through L3-4 inter-vertebral. Opioids were given intravenously to the mother for sedation after delivery of the baby. Satisfactory anesthesia and sedation was provided during surgery. The mother and the neonate were safe and no special complication was found after surgery. Our case demonstrated that low-dose spinal anesthesia combined with epidural anesthesia with intravenous opioids can provide satisfactory anesthesia and sedation, and reduce the risk of heart failure and thyroid storm.

    Pregnancy in presence of severe aortic stenosis (AS) causes worsening of symptoms needing further intervention. In the advanced stages of pregnancy, some patients may even require aortic valve replacement (AVR) and cesarean delivery in the same sitting. Opioid based general anesthesia for combined lower segment cesarean section (LSCS) with AVR has been described. However, the use of opioid may lead to fetal morbidity and need of respiratory support for the baby. We describe successful anesthetic management for LSCS with AVR in a >33 week gravida with severe AS and congestive heart failure. We avoided opioids till delivery of the baby AVR; the delivered neonate showed a normal APGAR score. PMID:25566720

    During labor and birth, considerable forces exerted on fetuses help instigate certain adaptive postpartum responses (viz., breathing and suckling). To make precise, reliable measures of the forces experienced by rat fetuses during parturition, we developed a novel method for measuring intrauterine pressure (IUP) in late pregnant rats. A small (1.25 x 4cm) telemetric blood pressure sensor is fitted within a fluid-filled balloon, similar in size to a full term rat fetus. The balloon is surgically implanted in the uterus on Gestational Day 19 of the rats' 22-day pregnancy. During birth, dams are able to deliver their pups and the balloon. IUP arsenals are recorded during labor (G22 or 23) and birth. Data derived from a group of implanted rats indicated that pressures on the balloon increased across the period of birth, reaching 18 mmHg during labor, 25 mmHg during pup births and 39 mmHg just prior to delivery of the balloon. These data are within the range reported for conventional IUP measurement techniques. Dams are simultaneously videotaped, enabling us to analyze behavioral expressions of labor contractions and to integrate in-situ and behavioral findings.

    Object Treatment options for anaplastic or malignant intramedullary spinal cord tumors (IMSCTs) remain limited. Paclitaxel has potent cytotoxicity against experimental intracranial gliomas and could be beneficial in the treatment of IMSCTs, but poor CNS penetration and significant toxicity limit its use. Such limitations could be overcome with local intratumoral delivery. Paclitaxel has been previously incorporated into a biodegradable gel depot delivery system (OncoGel) and in this study the authors evaluated the safety of intramedullary injections of OncoGel in rats and its efficacy against an intramedullary rat gliosarcoma. Methods Safety of intramedullary OncoGel was tested in 12 Fischer-344 rats using OncoGel concentrations of 1.5 and 6.0 mg/ml (5 μl); median survival and functional motor scores (Basso-Beattie-Bresnahan [BBB] scale) were compared with those obtained with placebo (ReGel) and medium-only injections. Efficacy of OncoGel was tested in 61 Fischer-344 rats implanted with an intramedullary injection of 9L gliosarcoma containing 100,000 cells in 5 μl of medium, and randomized to receive OncoGel administered on the same day (in 32 rats) or 5 days after tumor implantation (in 29 rats) using either 1.5 mg/ml or 3.0 mg/ml doses of paclitaxel. Median survival and BBB scores were compared with those of ReGel-treated and tumor-only rats. Animals were killed after the onset of deficits for histopathological analysis. Results OncoGel was safe for intramedullary injection in rats in doses up to 5 μl of 3.0 mg/ml of paclitaxel; a dose of 5 μl of 6.0 mg/ml caused rapid deterioration in BBB scores. OncoGel at concentrations of 1.5 mg/ml and 3.0 mg/ml paclitaxel given on both Day 0 and Day 5 prolonged median survival and preserved BBB scores compared with controls. OncoGel 1.5 mg/ml produced 62.5% long-term survivors when delivered on Day 0. A comparison between the 1.5 mg/ml and the 3.0 mg/ml doses showed higher median survival with the 1.5 mg/ml dose on Day 0, and no differences in median survival or BBB scores after treatment on Day 5. Conclusions OncoGel is safe for intramedullary injection in rats in doses up to 5 μl of 3.0 mg/ml, prolongs median survival, and increases functional motor scores in rats challenged with an intramedullary gliosarcoma at the doses tested. This study suggests that locally delivered chemotherapeutic agents could be of temporary benefit in the treatment of malignant IMSCTs under experimental settings. PMID:22208429

    The effects of 15 diseases on time until culling were studied in 39,727 Finnish Ayrshire cows that calved during 1993 and were followed until the next calving or culling. The diseases studied were: dystocia, milk fever, retained placenta, displacement of the abomasum, metritis, non-parturient paresis, ketosis, rumen disorders, acute mastitis, hypomagnesemia, lameness, traumatic reticuloperitonitis, anestrus, ovarian cysts, and teat injuries. Survival analysis, using the Cox proportional hazards model, was performed and diseases were modeled as time-dependent covariates. Different stages of lactation when culling can occur were also considered. Parity, calving season and herd were included as covariates in every model. Parity had a significant effect on culling, the risk of culling being four times higher for a cow in her sixth or higher parity than for a first parity cow. The effects of diseases varied according to when the diseases occurred and when culling occurred. Mastitis, teat injuries and lameness had a significant effect on culling throughout the whole lactation. Anestrus and ovarian cysts had a protective effect against culling at the time when they were diagnosed. In general, diseases affected culling decisions mostly at the time of their occurrence. The effect seemed to decrease with time from the diagnosis of the disease. However, milk fever, dystocia and metritis also had a significant effect on culling at the end of the lactation.

    Eleven late-pregnant Jersey cows were assigned to two groups; a group (PO-RBVD group) consisting of five cows treated with an oral administration of 10 million I.U. of an encapsulated form of vitamin D3 ("rumen-bypass" VD3; RBVD3) and another group (IMVD group) consisting of the other six treated with an intramuscular injection of 10 million I.U. of vitamin D3 (VD3). The cows received the RBVD3 or VD3 administration at 7 days before the expected parturition. The changes in the plasma concentrations of vitamin D metabolites, ionized Ca (Ca++) and inorganic phosphorus (iP) were evaluated. Of the vitamin D metabolites, the plasma 25-hydroxyvitamin D concentrations in PO-RBVD group increased significantly after the RBVD3 administration and remained in high levels that were significantly higher than those in IMVD group. This suggested that RBVD3 was absorbed rapidly and excellently from the post-ruminal digestive tract without the degradation by ruminal microorganisms. The plasma Ca++ and iP concentrations in PO-RBVD group tended to be higher after the administration and around parturition than those in IMVD group. From these observations, it was suggested the oral RBVD3 administration had more potent ability to prevent parturient paresis compared with the VD3 injection used widely in Japan. PMID:10823727

    Study Design: Prospective study. Objective: To investigate the efficacy of transcranial electrically stimulated muscle-evoked potentials (TcE-MsEPs) for predicting postoperative segmental upper extremity palsy following cervical laminoplasty. Summary of Background Data: Postoperative segmental upper extremity palsy, especially in the deltoid and biceps (so-called C5 palsy), is the most common complication following cervical laminoplasty. Some papers have reported that postoperative C5 palsy cannot be predicted by TcE-MsEPs, although others have reported that it can be predicted. Methods: This study included 160 consecutive cases that underwent open-door laminoplasty, and TcE-MsEP monitoring was performed in the biceps brachii, triceps brachii, abductor digiti minimi, tibialis anterior, and abductor hallucis. A >50% decrease in the wave amplitude was defined as an alarm point. According to the monitoring alarm, interventions were performed, which include steroid administration, foraminotomies, etc. Results: Postoperative deltoid and biceps palsy occurred in 5 cases. Among the 155 cases without segmental upper extremity palsy, there were no monitoring alarms. Among the 5 deltoid and biceps palsy cases, 3 had significant wave amplitude decreases in the biceps during surgery, and palsy occurred when the patients awoke from anesthesia (acute type). In the other 2 cases in which the palsy occurred 2 days after the operation (delayed type), there were no significant wave decreases. In all of the cases, the palsy was completely resolved within 6 months. Discussion: The majority of C5 palsies have been reported to occur several days after surgery, but some of them have been reported to occur immediately after surgery. Our results demonstrated that TcE-MsEPs can predict the acute type, whereas the delayed type cannot be predicted. Conclusions: A >50% wave amplitude decrease in the biceps is useful to predict acute-type segmental upper extremity palsy. Further examination about the interventions for monitoring alarm will be essential for preventing palsy. PMID:26147699

    The object of this study was to evaluate the usefulness of measuring the differences in the values of the serum total protein (DVSTP) concentration of foals and the refractometry index (DVRI) of the milk of dams before and after nursing of the colostrum for assessing failure of passive transfer (FPT) in foals. Serum samples from 31 foals were collected before the first nursing and other 1 to 6 times between 4 and 24 hr after birth. Paired colostrum and milk samples were collected from 14 of their dams at the same time. Serum samples were analyzed for IgG concentration using a single radial immunodiffusion (SRID) test (98 samples) and total protein concentration using a temperature-compensating refractometer (98 samples). Colostrum and milk samples were analyzed for refractometry index (RI) using a Brix refractometer (71 samples). DVSTP concentration and DVRI were significantly correlated with serum IgG concentration. The negative predictive values (NPVs) of DVSTP concentration for detecting serum IgG concentrations<400 mg/dl and<800 mg/dl were 98.2% and 91.3% when the cutoff value is set to 0.4 mg/dl and 0.8 mg/dl, respectively. Furthermore, the NPVs of DVRI for detecting serum IgG concentrations<400 mg/dl and<800 mg/dl were 97.3% and 96.3% when the cutoff value is set to 6% and 10%, respectively. The results suggest that measurement of DVRI is useful in assessing FPT as an initial "stall-side" screening test, because it is easy, inexpensive to perform and allows for rapid interpretation.

    Background. Measures of spousal effect during parturient pain should take a tripartite approach involving the parturients, spouses, and midwives. Aim. To develop and validate three questionnaires measuring spousal presence in management of parturient pain in Nigeria. Methods. There are two phases: (1) development of questionnaires, Abuja Instrument for Midwives (AIM), Abuja Instrument for Parturient Pain (AIPP), and Abuja Instrument for Parturient Spouses (AIPS), utilizing literatures, Kuopio instrument for fathers (KIF) and expertise of health professionals, and (2) pilot study to validate the questionnaires which were administered in two hospitals in Nigeria: midwives (n = 10), parturients (n = 10), and spouses (n = 10).  Results. Internal consistency for the three questionnaires indicated Cronbach's alpha coefficient of 0.789 (AIM), 0.802 (AIPP), and 0.860 (AIPS), while test-retest reliability was r = 0.99 (AIM), r = 0.99 (AIPP), and r = 0.90 (AIPS). Conclusions. AIM, AIPP, and AIPS provide a means of investigating the effectiveness of spousal presence in management of parturient pain in Nigeria. However, further testing of each instrument is needed in a larger population to replicate the beneficial findings of AIMS, AIPP, and AIPS which can contribute rigor to future studies. PMID:26682066

    Dengue infection has not been routinely investigated among pregnant women and parturients with acute febrile syndrome in endemic settings. Here, we report two cases of dengue fever detected at the time of delivery in parturients enrolled in a cohort prospective study conducted in a hospital in Recife, Brazil. The parturients reported fever onset within seven days prior to delivery, and dengue infection was confirmed upon detection of viral ribonucleic acid (RNA) by using the reverse transcriptase-polymerase chain reaction. Dengue infection should be considered as a diagnostic possibility in cases of fever during pregnancy and labor, especially in endemic areas. PMID:27384840

    We describe the management of a parturient woman with hypertrophic cardiomyopathy who developed a symptomatic accelerated idioventricular rhythm who required an urgent cesarean delivery at 32 weeks. Transthoracic echocardiography helped guide anesthetic management, including epidural dosing, fluid management, and phenylephrine infusion rates. This case demonstrates the application of transthoracic echocardiography to guide anesthetic management in a parturient woman at risk for cardiovascular compromise. PMID:26720049

    Vocal cord paralysis has diverse etiologies. In the present study, vocal chord paralysis caused by surgery/trauma was present in more than two thirds of the cases, followed by primary malignancy-associated paralysis. Thyroidectomy was the most common cause in bilateral paresis, especially if performed in recurrent or malignant disease. Voice therapy was promising in pa-tients with unilateral paresis and hoarseness as main symptom. Persistent dysphonia due to insufficiency of the glottic closure led to an operative glottis restricting procedure in only 6% of cases. In almost half the patients with dyspnea as the main symp-tom of bilateral vocal cord paresis, temporary tracheotomy or surgical glottis widening procedures had to be performed. The group of idiopathic and traumatic paresis patients showed the best spontaneous recovery within the first 12 months in comparison to primary malignancy-associated paralysis, which showed no recovery of the recurrens nerve.

    Obesity is a worldwide epidemic. It is associated with increased comorbidities and increased maternal, fetal, and neonatal complications. The risk of cesarean delivery is also increased in obese parturients. Anesthetic management of the obese parturient is challenging and requires adequate planning. Therefore, those patients should be referred to antenatal anesthetic consultation. Anesthesia-related complications and maternal mortality are increased in this patient population. The risk of difficult intubation is increased in obese patients. Neuraxial techniques are the preferred anesthetic techniques for cesarean delivery in obese parturients but can be technically challenging. An existing labor epidural catheter can be topped up for cesarean delivery. In patients who do not have a well-functioning labor epidural, a combined spinal epidural technique might be preferred over a single-shot spinal technique since it is technically easier in obese parturients and allows for extending the duration of the block as required. A continuous spinal technique can also be considered. Studies suggest that there is no need to reduce the dose of spinal bupivacaine in the obese parturient, but there is little data about spinal dosing in super obese parturients. Intraoperatively, patients should be placed in a ramped position, with close monitoring of ventilation and hemodynamic status. Adequate postoperative analgesia is crucial to allow for early mobilization. This can be achieved using a multimodal regimen incorporating neuraxial morphine (with appropriate observations) with scheduled nonsteroidal anti-inflammatory drugs and acetaminophen. Thromboprophylaxis is also important in this patient population due to the increased risk of thromboembolic complications. These patients should be monitored carefully in the postoperative period, since there is increased risk of postoperative complications in the morbidly obese parturients. PMID:27574464

    Background Third-generation hydroxyethyl starch (HES) solutions have been developed to minimize negative effects on hemostasis. In normal pregnancy, the coagulation activity increases, reaching a maximum around term. This study examined the effects of hemodilution with HES 130/0.4 (6%) on blood coagulation in parturients in vivo and in vitro. Methods Forty parturients scheduled for cesarean sections were assigned randomly to receive either 500 or 1,000 ml of HES 130/0.4 (6%). Rotation thromboelastometry (ROTEM®) measurements were performed before and after administering HES 130/0.4 (6%). In addition, blood samples obtained from 20 randomly selected parturients were diluted 10% to 40% using HES 130/0.4 (6%), and ROTEM® measurements were performed before and after dilution. The changes from baseline and the effects of dilution were analyzed by ROTEM® parameters. Results Infusions of 500 or 1,000 ml of HES 130/0.4 (6%) in the parturients altered the clot formation time, α angle, and maximal clot firmness, although all remained within normal ranges. HES 130/0.4 (6%) affected in vitro blood coagulation in parturients' blood containing 10, 20, 30, and 40% HES. The clotting time was prolonged at each dilution percentage, but remained within the normal range. Other parameters showed an impairment of the coagulation system. Conclusions Blood coagulation in parturients may be compromised at high dilution ratios of HES 130/0.4 (6%) to blood. Nevertheless, the infusion of 1,000 ml of HES 130/0.4 (6%) in normal parturients did not significantly affect blood coagulation. PMID:22558500

    We have used the up-and-down allocation technique to assess the relative analgesic potencies of epidural ropivacaine alone and ropivacaine combined with sufentanil 0.75 microg.ml-1 in 42 women requesting epidural analgesia in the first stage of labour. Parturients were randomly allocated to one of the two epidural solutions in a double-blind manner. The concentration of local anaesthetic was determined by the response of the previous parturient: an effective concentration (pain < or = 10 mm on a 10-cm visual analogue pain score within 30 min) resulted in a 0.01% decrease in the concentration of ropivacaine for the next parturient, an ineffective concentration resulted in a 0.01% increase. Minimum local analgesic concentration of ropivacaine alone was 0.13% (95% CI 0.12-0.13%) compared with 0.09% (95% CI 0.08-0.1%) for ropivacaine with sufentanil (p < 0.00001). PMID:11412157

    Maternal complete heart block can pose significant challenges for the anesthesiologist in the antepartum, peripartum, and postpartum periods. Some patients may present for the first time in the puerperium with dizziness, weakness, syncope, or congestive heart failure as a result of the additional hemodynamic burden that accompanies pregnancy. Although there is an increase in permanent pacemaker placement in young symptomatic patients before pregnancy, prophylactic placement of pacemakers in asymptomatic parturients is not always indicated. The need for temporary or permanent pacemakers in asymptomatic women should be assessed on a case-by-case basis; many of these patients may be safely managed during labor and delivery without pacing. The parturient with complete heart block must be followed vigilantly during pregnancy and post delivery, as the need for pacemaker insertion can also arise in the postpartum period. We present a case of third-degree heart block in a 26-year-old parturient. PMID:27555134

    The use of imaging techniques in women who are pregnant has increased greatly over the past decade. This focused review discusses the risks and indications of ultrasonography, magnetic resonance imaging, computed tomographic scanning, and fluoroscopy for the evaluation of the parturient with non-obstetric disorders. Diagnostic imaging of the pregnant woman for the evaluation of disorders not related to pregnancy is evolving, and protocols will vary from institution to institution. The potential benefit from indicated diagnostic radiological procedures in the parturient nearly always outweighs risk to the fetus because radiation exposure from a single procedure conveys little fetal risk.

    The development of acute abdominal pain in a laboring parturient after a previous cesarean delivery is of concern and may be the result of a potentially life-threatening condition such as uterine rupture. We present a case of a parturient with type II diabetes mellitus, who had undergone 2 previous cesarean deliveries and now presented in labor with increasing abdominal pain. An emergency cesarean delivery was performed for probable uterine rupture. Intraoperatively, the patient was noted to be severely hypocarbic with significant metabolic acidosis, and the diagnosis of diabetic ketoacidosis was established. PMID:26825994

    Herpes zoster, commonly known as shingles, is an infectious viral disease characterized by painful, unilateral skin blisters occurring in specific sensory dermatomes. Motor paresis is reported in 0.5% to 5% of patients. Although the mechanism of zoster paresis is still unclear, the virus can spread from the dorsal root ganglia to the anterior horn cell or anterior spinal nerve roots. It rarely involves the brachial plexus. We report a case of brachial plexitis following herpes zoster infection in which pathological lesions were diagnosed using brachial plexus magnetic resonance imaging and treated with ultrasound-guided perineural corticosteroid injection.

    Background Mutual health organizations (MHO) have been seen as a promising alternative to the fee-based funding model but scientific foundations to support their generalization are still limited. Very little is known about the extent of the impact of MHOs on health-seeking behaviours, quality and costs. Methodology/Principal Findings We present the results of an evaluation of the effects attributable to membership in an MHO in a rural region of Benin. Two prospective studies of users (parturients and hospitalized patients) were conducted on the territory of an inter-mutual consisting of 10 MHOs and as many healthcare centres (one, Ouessé, serving as a referral hospital) and one hospital (Papané). Members and non-members were matched (142 pairs of parturients and 109 triads of hospitalized patients) and multilevel multiple regression was used. Results show that member parturients went to healthcare centres sooner (p = 0.049) and were discharged more quickly after delivery (p = 0.001) than non-members. Length of stay in some cases was longer for hospitalized member parturients (+41%). Being a member did not shorten hospital stay, total length of episode of care, or time between appearance of symptoms and recourse to care. Regarding expenses, member parturients paid one-third less than non-members for a delivery. For hospitalized patients, the average savings for members was around $35 US. Total expenses incurred by patients hospitalized at Papané Hospital were higher than at Ouessé but the two hospitals’ relative advantages were comparable at −36% and −39%, respectively. Conclusion/Significance These results confirm mutual health organizations’ capacity to protect households financially, even if benefits for the poor have not been clearly determined. The search for scientific evidence should continue, to understand their impacts with regard to services obtained by their members. PMID:23077556

    Continuous interscalene block is an approved modality for postoperative pain control, but it may cause hemidiaphragmatic paresis. In this study we aimed to determine whether continuous supraclavicular block would provide postoperative analgesia comparable to that of continuous interscalene block and reduce the incidence of hemidiaphragmatic paresis. Patients scheduled for open rotator cuff repair were randomly allocated to receive continuous interscalene (n = 38) or supraclavicular block (n = 37). Both participants and assessing clinicians were blinded to the group allocation. The primary endpoint was the mean pain intensity 24 h after the surgery. Postoperative mean (SD) pain scores at 24 h were similar in the supraclavicular and interscalene groups (2.57 (1.71) vs 2.84 (1.75) respectively; p = 0.478). The incidence of complete or partial hemidiaphragmatic paresis was lower in the supraclavicular group at 1 h after admission to the postanaesthetic care unit and 24 h after the surgery [25 (68%) vs 38 (100%); p = 0.001 and 14 (38%) vs 27 (71%) respectively; p = 0.008]. Continuous supraclavicular block provided comparable analgesia compared with interscalene block with a reduced incidence of complete or partial hemidiaphragmatic paresis for 24 h following surgery.

    Gastroparesis is a syndrome characterized by delayed gastric emptying in the absence of mechanical obstruction. The most common underlying aetiology is diabetes mellitus; however, many cases are idiopathic. Pregnancy per se is associated with gastrointestinal neuromuscular dysfunction; however, reports of gastroparesis arising during pregnancy are rare. We report a case of severe gastroparesis and proximal small bowel paresis presenting during pregnancy.

    Southern, D A; Callanan, V I; Gordon, G S

    We describe cases of five patients with taipan envenomation which indicate that patients with paresis benefit from repeated doses of antivenom, even if given long after the bite, and that fresh frozen plasma should be given to correct coagulopathy that persists after reversal of neuromuscular blockade. We reiterate the importance of compression bandages. PMID:8985453

  4. Parenteral opioids for labor analgesia.

    PubMed

    Campbell, David C

    2003-09-01

    Labor pain relief is an important aspect of women's health that has historically been neglected. Epidural analgesia is the only consistently effective method of labor pain relief and has recently undergone substantial improvements to address the concerns of both parturients and obstetric care providers. With increased physician awareness, these recent advances are becoming more widely accepted and routinely available for all laboring parturients. Unfortunately, an increasing number of women are presenting to maternity wards with an absolute contraindication to epidural labor analgesia. The present review will provide an outline of the recent developments in parenteral analgesic options which complement modern epidural analgesic techniques. Protocols for the initiation of "state-of-the-art" parenteral analgesic techniques are provided as a guide to facilitate effective, modern, parenteral labor analgesia. PMID:12972743

  5. Placentophagia in Weanling Female Laboratory Rats

    PubMed Central

    Harding, Kaitlyn M.; Lonstein, Joseph S.

    2014-01-01

    Placentophagia is common in parturient mammals and offers physiological and behavioral advantages for mothers. In natural environments, weanlings are often present during the birth of younger siblings, but it is unknown if weanling rats are placentophagic or prefer placenta over other substances. To examine this, primiparous rats were remated during the postpartum estrus and weanling females remained in the nest during their mother’s next parturition. Continuous observation revealed that 58% of weanlings were placentophagic. To determine if this placentophagia occurs away from parturient mothers, weanling females still living in their natal nest were offered placenta, liver, or cake frosting in a novel chamber. They ingested more placenta and liver than frosting. Thus, many weanling female laboratory rats are placentophagic during birth of younger siblings but do not selectively prefer placenta when tested outside their natal nest. Consequences of placentophagia by weanlings are unknown, but it may promote their alloparenting or postpartum mothering. PMID:24604548

    One hundred and thirty-three paturients who had received either methoxyflurane-nitrous oxide or nitrous oxide analgesia with or without pudendal block, underwent the Eysenck Personality Inventory Test on the second postpartum day and evaluated their memory of the pain (Subjectively Evaluated Pain Suffering Scores) during labor. Parturients who had received methoxyflurance-nitrous oxide analgesia reported significantly lower pain suffering than parturients who had had nitrous oxide analgesia. Subdivision according to Personality Inventory factors showed that at the introvert end of the Extroversion-Introversion scale, methoxyflurance-nitrous oxide analgesia with or without additional pudendal block resulted in significantly lower pain suffering than did not nitrous oxide analgesia. On the other hand, nitrous oxide analgesia without additional pudendal block gave significantly lower pain suffering at the extrovert end of the scale. Among the extroverts there was a tendency, though not statistically significant, towards non-approval of the pudendal block. PMID:7424496

    Of 2233 parturients, 170 cases with evidence of meconium during delivery were examined. We tried to establish the correlation between the appearance of meconium and the occurance of contraction induced FHR-decelerations in continuous intra partum monitoring. In addition we purposed to determine, whether the appearing of meconium during labor can be used as a clinical prognosite sign for fetal outcome. Our data support the assumption that the passage of meconium during any stage of labor only represents a sign of potential fetal distress showing the intra partum records pathology FHF-patterns. The appearance of meconium alone -- diagnosed at the time of the entrance of parturients or in an advanced stage of labor -- demands supplemented diagnostic methods for a better interpreting of an actual or compensated fetal distress.

    The association between blood calcium levels and electrocardiographic variables was compared in 137 normal parturient and 36 peripartum recumbent Holstein cows to determine whether hypocalcemia in peripartum dairy cows can be rapidly diagnosed using electrocardiograph. Inverse of STc (ST peak interval/SS interval(0.5)) and blood ionized calcium or serum calcium concentrations were strongly correlated, and both correlation coefficients were 0.81 (P<0.001). The 95% prediction interval indicated that cows with STc >0.385 ± 0.001 sec are very likely to be hypocalcemic (blood ionized or serum calcium concentrations of <0.9 mmol/l or <7.5 mg/dl, respectively). These findings indicate that hypocalcemia in parturient cows can be non-invasively estimated using the STc. PMID:26118411

    2001-08-01

    The photoperiodic control of sexual rest in Armadillidium vulgare was investigated using various experimental protocols. When reared in conditions of a Nanda-Hamner (i.e. resonance) protocol from their first parturial moult to their post experimental moult, females showed a weak resonance effect in sexual rest incidence. The transfer from a long day cycle to a symmetrical skeleton photoperiod--consisting of two equal light pulses per 24 h of continuous darkness--revealed the involvement of a circadian oscillatory system in the photoperiodic clock of this species. The data, obtained in the whole experiments, suggested that both oscillator and hourglass features are involved in the photoperiodic response controlling the sexual rest in Armadillidium vulgare. Moreover, when non-24-h light-dark cycles (with a long photophase) were applied, a mechanism responsible of arrest of reproduction also implied a photoperiodic counter which accumulated and added up the photoperiodic information within a sensitive period during post parturial intermoult.

    The incidence of cirrhosis and advanced portal hypertension during pregnancy is very low, and the literature is scarce with regard to the anesthetic management of a parturient with this coexisting disease. We report the successful perioperative management of a parturi- ent with a history of cirrhosis and portal hypertension with esophageal varices and mild preeclampsia who presented at 38 weeks' gestation in active labor with a breech presentation requiring emergency cesarean delivery. She required endoscopic esophageal varices banding during the second trimester of pregnancy. After correction of her coagulopathy, she was administered subarachnoid block and cesarean delivery, which was conducted uneventfully. Anesthetic management of these patients depends on understanding and avoiding variceal hemorrhage, encephalopathy, renal failure, and careful fluid and electrolyte management. PMID:26050279

    Amniotic fluid embolism (AFE) is a rare obstetric catastrophe with an incidence of 7.7 per 100 000 deliveries and mortality as high as 60% to 80%. We describe a case of perioperative cardiac arrest in a young parturient undergoing an emergent cesarean section. Just after delivery of live healthy male baby, patient developed disseminated intravascular coagulation not responding to resuscitation with fluids and blood products. Her autopsy revealed edematous lungs with amniotic fluid debris within pulmonary vessels thus establishing the diagnosis of AFE. Amniotic fluid embolism is life threatening and difficult to predict or prevent condition, which should be always be kept in mind in a parturient with sudden cardiovascular collapse, so that resuscitation commences immediately, as early intervention is essential for a positive outcome.

    2015-08-01

    Epidural blood patching is an effective treatment for postdural puncture headache but has potential risks. Arachnoiditis is a very rare disabling condition and few cases have been described following an epidural blood patch. We present a case of chronic adhesive arachnoiditis in a parturient treated with a repeat epidural blood patch. A healthy 29-year-old woman had an accidental dural puncture following epidural insertion during labour. Initial treatment of postdural puncture headache with an epidural blood patch was ineffective and was therefore repeated. She gradually developed severe neurological symptoms consistent with arachnoiditis confirmed with magnetic resonance imaging. Despite intensive multimodal treatment with analgesics and physiotherapy, her neurological condition remains unresolved two years later. This serious but rare complication should encourage caution when treating parturients with postdural puncture headache with a repeat epidural blood patch. PMID:26119259

    2016-08-01

    To investigate the role of cerebral oxygen saturation (ScO2) for prediction of hypotension after spinal anesthesia for caesarean section. Forty-five parturients undergoing elective caesarean section under spinal anesthesia were selected. Blood pressure, heart rate and pulse oxygen saturation before and after anesthesia were recorded, and the association between changes in ScO2 before and after anesthesia with hypotension after spinal anesthesia was explored. Hypotension occurred in 32 parturients after spinal anesthesia. The decrease in ScO2 after spinal anesthesia in parturients with hypotension was larger than in parturients without hypotension (P < 0.05). The duration from the intrathecal injection to 5 % decrease in ScO2 was shorter than that from the intrathecal injection to the occurrence of hypotension (P < 0.05). The mean time from 5 % decrease in ScO2 to hypotension was 38 s. The area under the receiver operation characteristic curve was 0.83 for decrease in ScO2 for prediction of hypotension (P < 0.05), and the optimal threshold value was 4.5 %. The sensitivity, specificity, positive predictive value and negative predictive value of 4.5 % decrease in ScO2 for prediction of hypotension were 0.75, 0.78, 0.92 and 0.47, respectively. The decrease in ScO2 after spinal anesthesia is associated with hypotension after spinal anesthesia for cesarean section, and may be a clinically useful predictor. PMID:26186992

    This study aimed to measure the synthesis of Th1 and Th2 cytokines by mononuclear cells after culture with live T. gondii and identified Th17 (CD4+) and Tc17 (CD8+) cells in toxoplasma-seronegative and toxoplasma-seropositive parturient and nonpregnant women. Cytometric bead arrays were used to measure cytokine levels (IL-2, TNF-α, IFN-γ, IL-4, IL-5, and IL-10); immunophenotyping was used to characterize Th17 and Tc17 cells, and the cells were stained with antibodies against CD4+ and CD8+ T cells expressing IL-17. The addition of tachyzoites to cell cultures induced the synthesis of IL-5, IL-10, and TNF-α by cells from seronegative parturient women and of IL-5 and IL-10 by cells from seropositive, nonpregnant women. We observed a lower level of IL-17-expressing CD4+ and CD8+ T lymphocytes in cultures of cells from seronegative and seropositive parturient and nonpregnant women that were stimulated with tachyzoites, whereas analysis of the CD4+ and CD8+ T cell populations showed a higher level of CD4+ T cells compared with CD8+ T cells. These results suggest that the cytokine pattern and IL-17-expressing CD4+ and CD8+ T lymphocytes may have important roles in the inflammatory response to T. gondii, thus contributing to the maintenance of pregnancy and control of parasite invasion and replication.

  5. Individual variation in the seasonal reproduction of the terrestrial isopod Armadillidium vulgare Latr. (Crustacea, Oniscidea)

    1998-08-01

    Under particular conditions of photoperiod and temperature, Armadillidium vulgare females, originating from a single population, might exhibit individual differences in the onset of reproduction and duration of the breeding period. In a population issued from a strain from middle latitudes, some females underwent only one parturial moult (northern tendency) and others three parturial moults (southern tendency). Females with an atypical northern phenology are the most numerous and tend to be found near the Danish population. In the latter, there is an asymmetrical response to laboratory selection (favourable to females with a longer breeding period). The asymmetrical variation in atypical individuals acts as a safety device against the unpredictability of the environment. The adaptation of this species, originally from the Mediterranean periphery, to a northern environment has led to a reduction in its capacity to breed over long periods of time. Populations from middle latitudes can undergo one or several parturial moults which enables the species to successfully colonize even far-away countries. These intrapopulation differences have an essential role and explain why Armadillidium vulgare is one of the most widely distributed species among Oniscidea.

    Fearing the devastating neurological complications in a parturient with the von Willebrand disease secondary to paucity of studies defining the guidelines to assess the risk of bleeding complications, anesthesiologists are often reluctant to administer neuroaxial anesthesia. We present a case report of a parturient with type I von Willebrand disease who presented for induction of labor at 39 weeks of gestation. After consultation with the hematologist well ahead of the conception, appropriate laboratory workup including clotting factor levels including FVIII, vWF:RcoF, vWF:Ag on different occasions peripartum, and provision of adequate prophylactic medical treatment, she underwent Cesarean section under epidural anesthesia without neurological or bleeding complications. von Willebrand disease is the most common inherited bleeding disorder that may result in various bleeding complications in a parturient as a result of hemostatic challenges during pregnancy. Yet the recommendations are based on anecdotal observations of the authors of small case series and surveys. Our case report emphasizes the importance of advanced planning, careful patient assessment, and multi-disciplinary team approach for the successful regional anesthesia as suggested by the guidelines based on clinical experiences.

    PubMed

    Schlumbohm, J

    2001-01-01

    Drawing on the admission records, the medical casebooks and the publications of its director, this article explores how the University of Göttingen's maternity hospital achieved its three official goals: teaching medical students, training female midwives, and providing shelter for needy parturient women. Since educating medical men was the most important aim of the hospital, the paper particularly focuses on how the demands of instruction shaped day-to-day obstetrical practices, especially under the directorship of Professor Friedrich Benjamin Osiander (1792-1822). He was a keen advocate of the forceps, whereas the first director, Professor Johann Georg Roederer (1751-63), had taken a moderate, that is a much less interventionist, approach to obstetrics. Osiander avowedly was determined to subordinate the parturient women to the demands of the clinic and to treat them as 'living manikins'. In spite of that, there is evidence that the pregnant and parturient women, most of whom were unmarried and from the lower classes, made use of the lying-in hospital for their own purposes, and that sometimes they refused to play the role assigned to them. The link between the maternity hospital and the rise of the man-midwife and of 'scientific' obstetrics appears to have been particularly strong in the case of Göttingen and other German university hospitals, compared with lying-in hospitals in other countries where the link was more indirect.

    We compared habitat use, forage characteristics, and group size among preparturient, parturient, and nonparturient female caribou (Rangifer tarandus) during and after the birthing season to test hypotheses involving acquisition of forage and risk of predation. We monitored 39 radiocollared females from the Mentasta caribou herd, Alaska, in 1994 and 40 animals in 1995. Group size of females giving birth at higher elevations was smaller (P 0.5). During peak parturition, females with young used sites with fewer predators (P < 0.05), a lower abundance of forage (P < 0.05), but with variable forage quality compared with those sites used by females without young. We hypothesized that parturient females used birth sites that lowered risk of predation, and traded-off forage abundance for increased safety. Nonetheless, few differences existed between parturient and nonparturient females in composition of diet or in indices of diet quality; we could not demonstrate a nutritional cost to maternal females from our analyses. We suggest that increasing population density might intensify intraspecific competition among females for birth sites, and thereby increase nutritional costs of using high-elevation areas with less forage but fewer predators.

    Oculomotor nerve palsy can be due to varied causes that include diabetic neuropathy, myasthenia gravis, brainstem infarction, demyelinating conditions, and cerebral aneurysms. Among the aneurysmal causes of oculomotor nerve palsy, aneurysm of the posterior communicating artery has been observed to be the most common. Pupillary dysfunction is considered to be an important feature of aneurysmal oculomotor nerve paresis. A case of a 7-year-old boy with partial oculomotor nerve palsy with pupillary sparing is being reported here, the etiology of which is tortuous and ectatic distal internal carotid artery. This is a rare cause of oculomotor nerve paresis and to the best of our knowledge has not yet been reported in children. Ischemia rather than compression seems to be the most plausible cause in this case. PMID:27606031

    Transcranial magnetic stimulation (TMS) is a noninvasive activation method that is increasingly used for motor mapping. Preoperative functional mapping in vascular surgery is not routinely performed; however, in cases of high-grade arteriovenous malformations (AVMs), it could play a role in preoperative decision making. A 16-year-old male was suffering from a giant, right-sided insular, Spetzler-Martin Grade V AVM. This patient's history included 3 hemorrhagic strokes in the past 3 years, resulting in Medical Research Council Grade 2-3 (proximal) and 2-4 (distal) paresis of the left side of the body and hydrocephalus requiring a ventriculoperitoneal shunt. Preoperative TMS showed absent contralateral innervation of the remaining left-sided motor functions. Subsequently, the AVM was completely resected without any postoperative increase of the left-sided paresis. This case shows that TMS can support decision making in AVM treatment by mapping motor functions. PMID:24866824

    The terms used to describe vocal fold motion impairment are confusing and not standardized. This results in a failure to communicate accurately and to major limitations of interpreting research studies involving vocal fold impairment. We propose standard nomenclature for reporting vocal fold impairment. Overarching terms of vocal fold immobility and hypomobility are rigorously defined. This includes assessment techniques and inclusion and exclusion criteria for determining vocal fold immobility and hypomobility. In addition, criteria for use of the following terms have been outlined in detail: vocal fold paralysis, vocal fold paresis, vocal fold immobility/hypomobility associated with mechanical impairment of the crico-arytenoid joint and vocal fold immobility/hypomobility related to laryngeal malignant disease. This represents the first rigorously defined vocal fold motion impairment nomenclature system. This provides detailed definitions to the terms vocal fold paralysis and vocal fold paresis.

    During a 1-year period, 8400 patient presentations to a psychiatric emergency service were screened for the conversion symptom of extremity paresis/paralysis. Of 4220 unduplicated presentations, three patients had this complaint. These cases were reviewed and followed up. All had received a DSM-III diagnosis of conversion disorder, but in each case the patient's conversion symptom was attributed to organic disease. This had medicolegal consequences in one case and threatened legal consequences in the others. Although the frequency of this alleged conversion symptom was 0.07%, in reality it was 0.0%. Guidelines for the management of the alleged conversion symptom of paresis/paralysis are discussed. PMID:1855657

    2009-12-01

    An Alaskan husky puppy was examined for a neurologic disease which began at six weeks of age with generalised paresis that progressed resulting in recumbency by 18 weeks. Thoracic limbs primarily exhibited lower motor neuron signs that included distal muscle atrophy and persistent elbow and carpal flexion that resisted manual extension. Pelvic limb signs primarily exhibited upper motor neuron and general proprioceptive deficits, but also included lower motor neuron signs. Abnormal vocalisation suggested a laryngeal paresis. Histopathologic lesions included a diffuse axonopathy and secondary demyelination in the nerves of the limbs and larynx and a similar bilaterally symmetrical degeneration in the spinal cord white matter suggestive of a dying back axonopathy. In addition, a degenerative process was present in nuclei in the brain stem and cerebellum. Recognition of this disease through clinical and pathologic examination in other related Alaskan Huskies suggested an autosomal recessive inherited disorder. PMID:19954445

    Post-polio syndrome occurs 30-40 years after polio virus infection. The main symptoms of PPS are slowly progressive muscle limbs paresis with muscle atrophy, joints pain, paresthesia. In 90% of patients the main symptom is fatigue that leads to physical and mental activity deterioration. The cause of disease remains unknown. Probably it is an effect of motoneurons damage during acute virus polio infection, their overloading and degeneration of remaining ones. In this study we described a case of man who developed PPS 36 years after Heine-Medin disease. The main symptom was intensification of right limb paresis and muscle atrophy. In electromyography there were damage features of muscle clinically affected and unaffected. Changes in lifestyle made possible to continue occupational activity. PMID:26277176

    Examination of 2 life masks of Abraham Lincoln's face was performed by means of 3-dimensional laser surface scanning. This technique enabled documentation and analysis of Lincoln's facial contours and demonstrated his marked facial asymmetry, particularly evident in the smaller left superior orbital rim. This may have led to retroplacement of the trochlea on the left side, leading, in turn, to the mild superior oblique paresis that was manifested intermittently during adulthood. PMID:17698764

Thus, also in this population the evaluation of cervical potentials can be done according to the known criteria. PMID:2110891

    The aim of this study was to evaluate the effect of mirror therapy on arm and hand function in subacute stroke in patients. The study included 60 hemiparetic right-handed patients after ischemic stroke 8-10 weeks after onset. They underwent stationary comprehensive rehabilitation in the rehabilitation centre. They were divided into two randomly assigned groups: mirror (n=30) and control (n=30). For both groups, two subgroups were created: one that included patients with right arm paresis (n=15) and the other that included patients with left arm paresis (n=15). The mirror group received an additional intervention: training with a mirror for 5 days/week, 2 sessions/day, for 21 days. Each single session lasted for 15 min. The control group (n=30) underwent a conventional rehabilitation program without mirror therapy. To evaluate self-care in performing activities of daily living, the Functional Index 'Repty' was used. To evaluate hand and arm function, the Frenchay Arm Test and the Motor Status Score were used. Measurements were performed twice: before and after 21 days of applied rehabilitation. No significant improvement in hand and arm function in both subgroups in Frenchay Arm Test and Motor Status Score scales was observed. However, there was a significant improvement in self-care of activities of daily living in the right arm paresis subgroup in the mirror group measured using the Functional Index 'Repty'. Mirror therapy improves self-care of activities of daily living for patients with right arm paresis after stroke. PMID:23528388

    In order to develop evidence-based rehabilitation protocols post-stroke, one must first reconcile the vast heterogeneity in the post-stroke population and develop protocols to facilitate motor learning in the various subgroups. The main purpose of this study is to show that auditory constraints interact with the stage of recovery post-stroke to influence motor learning. We characterized the stages of upper limb recovery using task-based kinematic measures in 20 subjects with chronic hemiparesis. We used a bimanual wrist extension task, performed with a custom-made wrist trainer, to facilitate learning of wrist extension in the paretic hand under four auditory conditions: (1) without auditory cueing; (2) to non-musical happy sounds; (3) to self-selected music; and (4) to a metronome beat set at a comfortable tempo. Two bimanual trials (15 s each) were followed by one unimanual trial with the paretic hand over six cycles under each condition. Clinical metrics, wrist and arm kinematics, and electromyographic activity were recorded. Hierarchical cluster analysis with the Mahalanobis metric based on baseline speed and extent of wrist movement stratified subjects into three distinct groups, which reflected their stage of recovery: spastic paresis, spastic co-contraction, and minimal paresis. In spastic paresis, the metronome beat increased wrist extension, but also increased muscle co-activation across the wrist. In contrast, in spastic co-contraction, no auditory stimulation increased wrist extension and reduced co-activation. In minimal paresis, wrist extension did not improve under any condition. The results suggest that auditory task constraints interact with stage of recovery during motor learning after stroke, perhaps due to recruitment of distinct neural substrates over the course of recovery. The findings advance our understanding of the mechanisms of progression of motor recovery and lay the foundation for personalized treatment algorithms post-stroke. PMID

    Sturge-Weber syndrome is a sporadic congenital neurocutaneous disorder often related to varying degrees of motor impairment. The phenomenon of prolonged ictal paresis is a rare seizure sign that can be due to lesions affecting the centro-parietal lobe. Focal inhibitory motor seizures can be difficult to differentiate from other clinical entities such as stroke, migraine or postictal paresis. We describe the case of a 40-year-old patient suffering from Sturge-Weber syndrome, admitted due to prolonged right-sided hemiparesis following a usual seizure. Repeated EEGs during the prolonged deficit showed only intermittent left fronto-parietal sharp waves. (99m)Tc HMPAO-brain SPECT performed seven days after the last seizure showed a vast area of parieto-occipital hyperperfusion in the left hemisphere. Aggressive antiepileptic therapy dramatically improved the clinical symptoms and scintigraphic images, which corroborated the diagnosis of ictal paresis. This case highlights the role of SPECT in the evaluation of Sturge-Weber syndrome, not only to investigate progressive neurological deterioration, but also exacerbation of seizures or prolonged neurological deficits. In fact, it may be possible to document ongoing epileptic activity using SPECT, despite a non-contributory EEG, which may be of help in adapting a therapeutic strategy. PMID:26235101

    This study tested a protocol for a randomized controlled trial of therapeutic versus placebo shoulder strapping as an adjuvant intervention early after stroke. Despite widespread use, there is little evidence of the efficacy or acceptability of shoulder strapping to improve arm function in patients with shoulder paresis following stroke. This study tested a protocol designed to trial shoulder strapping as an adjuvant therapy in patients with shoulder paresis after stroke and tested its acceptability for patients and clinical staff. A multiple-method design comprised one quantitative randomized, double-blind, placebo-controlled study and two qualitative exploratory investigations entailing patient interviews and staff surveys. Seventeen sub-acute stroke patients with shoulder paresis were recruited in London stroke service settings between November 2007 and December 2009. Outcomes from a 4-week therapeutic strapping protocol were compared with those of placebo strapping as an adjunct to conventional rehabilitation. Minimal adverse events and greater improvement in arm function (Action Research Arm Test) were seen with therapeutic compared with placebo strapping (effect size 0.34). Patients and staff found the strapping acceptable with minimal adverse effects. This study provided data for sample size calculation and demonstrated a workable research protocol to investigate the efficacy of shoulder strapping as an adjuvant intervention to routine rehabilitation for stroke patients. Small-scale findings continue to flag the importance of investigating this topic. The protocol is recommended for a definitive trial of shoulder strapping as an adjuvant intervention. PMID:25664993

    Five red-footed tortoises (Geochelone carbonaria) treated for intestinal nematode parasitism with a single IM injection of ivermectin (0.4 mg/kg) were found in a state of extreme paresis or flaccid paralysis. One tortoise recovered normal motor function over the next 7 to 10 days. The remaining tortoises died within 3 days of receiving the ivermectin. The only consistent postmortem finding was a marked fatty change in the liver. Studies in the red-footed tortoise showed that some paresis will occur with dosages as low as 0.05 mg/kg. At least 3 other species of chelonians were found to be susceptible to ivermectin toxicosis at similar dosages (0.1 mg/kg or less). The leopard tortoise (Geochelone pardalis) appeared to be the most susceptible of the species tested, consistently developing mild paresis with a dosage of 0.025 mg/kg. Death occurred with dosages as low as 0.3 mg/kg. A dosage of 0.05 mg/kg was found to be safe in red-footed tortoises, provided that treatment was not repeated at intervals of less than 7 days. Shedding of nematode larvae and eggs in the feces of parasitized red-footed tortoises was prevented with 2 to 6 weekly IM injections of ivermectin at a dosage of 0.05 mg/kg, but limited necropsy findings indicated that elimination of adult nematodes from the intestines was incomplete.

    Background: Interpositional jump graft (IPJG) is a nerve graft axonally supercharged from the hypoglossal nerve. However, for using the technique, an autologous nerve, which should contain the great auricular and sural nerves, must be obtained. Depending on the donor site, unavoidable issues such as nerve disorders and postoperative scarring may appear. To reduce the issues, in this study, the authors developed an end-to-side neurorrhaphy technique with the recipient nerve and an artificial nerve conduit and investigated the efficacy of an IPJG with an artificial nerve conduit in a rat facial nerve paresis model. Methods: A ligature clip was used to crush the facial nerve trunk, thereby creating a partial facial nerve paresis model. An artificial nerve conduit was then prepared with a 10-mm-long silicone tube containing 10 μL type I collagen and used to create an IPJG between the facial nerve trunk and the hypoglossal nerve (the silicone tube group). Thirteen weeks after the surgery, the outcome was histologically and physiologically compared with conventional IPJG with autograft using the great auricular nerve. Results: Retrograde tracer test confirmed a double innervation by the facial and hypoglossal nerve nuclei. In the autograft and silicone tube groups, the regeneration of myelinated axons was observed. Conclusion: In this study, the authors successfully developed an end-to-side neurorrhaphy technique with the recipient nerve and an artificial nerve conduit, and revealed that an IPJG in the conduit was effective in the rat facial nerve paresis model.

    2015-04-01

    In patients with Ménière's disease (MD), caloric testing can show, depending on the stage and activity of the disease, a variety of results. Between attacks, many, or perhaps even most, patients with unilateral early or mild MD have normal caloric tests; late MD can show abnormalities ranging from mild to severe unilateral canal paresis with or without directional preponderance. The explanation of canal paresis in MD is not clear. The most obvious explanation, severe loss of lateral canal hair cells, is not likely to be correct because hair cell loss will not explain the fluctuating canal paresis to caloric stimulation. In contrast, the published evidence is that rotational testing of semicircular canal function in MD patients typically shows little reduction in function and even enhancement of vestibulo-ocular reflex gain, at least in the early stages of the disease. Here, we offer a novel explanation for this dissociation. We propose that hydropic expansion of the lateral canal membranous labyrinth permits convective recirculation within the duct that allows dissipation of the hydrostatic force that would normally cause cupular displacement and nystagmus in the caloric test.

    Objectives/Hypothesis Evaluate the influence of asymmetric recurrent laryngeal nerve (RLN) stimulation on the vibratory phase, acoustics and aerodynamics of phonation. Study Design Basic science study using an in vivo canine model. Methods The RLNs were symmetrically and asymmetrically stimulated over eight graded levels to test a range of vocal fold activation conditions from subtle paresis to paralysis. Vibratory phase, fundamental frequency (F0), subglottal pressure, and airflow were noted at phonation onset. The evaluations were repeated for three levels of symmetric superior laryngeal nerve (SLN) stimulation. Results Asymmetric laryngeal adductor activation from asymmetric left-right RLN stimulation led to a consistent pattern of vibratory phase asymmetry, with the more activated vocal fold leading in the opening phase of the glottal cycle and in mucosal wave amplitude. Vibratory amplitude asymmetry was also observed, with more lateral excursion of the glottis of the less activated side. Onset fundamental frequency was higher with asymmetric activation because the two RLNs were synergistic in decreasing F0, glottal width, and strain. Phonation onset pressure increased and airflow decreased with symmetric RLN activation. Conclusion Asymmetric laryngeal activation from RLN paresis and paralysis has consistent effects on vocal fold vibration, acoustics, and aerodynamics. This information may be useful in diagnosis and management of vocal fold paresis. PMID:24913182

    Inflammatory reaction is very important for formation of the neomembrane of chronic subdural hematoma (CSDH). The present study evaluated medical treatment with the platelet-activating factor receptor antagonist, etizolam, for the resolution of CSDH, and the factors indicating surgery or conservative therapy. Alternate patients were assigned to the etizolam group or control group without medical treatment. Patients in the etizolam group received 3.0 mg etizolam per day for 14 days. A total of 53 patients were followed up for at least 6 months. Univariate analysis of differences in demographic characteristics, clinical findings, and initial computed tomography (CT) findings, and multiple logistic regression analysis of the relationship between etizolam treatment and requirement for surgery using age, sex, low density of hematoma on CT, and paresis as confounders were performed. Etizolam treatment (adjusted odds ratio [OR] 0.156, 95% confidence interval [CI] 0.024-0.999, p = 0.049) was negatively correlated with requirement for surgery. Low density of hematoma (adjusted OR 0.125, 95% CI 0.019-0.846, p = 0.033) was found to be an independent negative predictor, and paresis as an initial symptom (adjusted OR 6.35, 95% CI 1.04-38.7, p = 0.045) was an independent positive predictor of requirement for surgery. Etizolam administration can promote the resolution of CSDH, especially at the stage of hygroma appearing as low density on CT. Surgery is recommended if the patient presents with paresis.

    Background and Purpose We report a novel finding of caloric conversion from normal responses into unilateral paresis during the acute phase of vestibular neuritis (VN). Methods We recruited 893 patients with a diagnosis of VN at Dizziness Clinic of Seoul National University Bundang Hospital from 2003 to 2014 after excluding 28 patients with isolated inferior divisional VN (n=14) and those without follow-up tests despite normal caloric responses initially (n=14). We retrospectively analyzed the neurotological findings in four (0.5%) of the patients who showed a conversion from initially normal caloric responses into unilateral paresis during the acute phase. Results In those four patients, the initial caloric tests were performed within 2 days of symptom onset, and conversion into unilateral caloric paresis was documented 1–4 days later. The clinical and laboratory findings during the initial evaluation were consistent with VN in all four patients except for normal findings in bedside head impulse tests in one of them. Conclusions Normal findings in caloric tests should be interpreted with caution during the acute phase of suspected VN. Follow-up evaluation should be considered when the findings of the initial caloric test are normal, but VN remains the most plausible diagnosis. PMID:26932259

    Background: Congenital abnormalities constitute one of the major causes of infant mortality, particularly in developing countries. The aim of this study was to describe the epidemiology of congenital anomalies in Cote d’Ivoire. Materials and Methods: It was a multicentric study of three academic hospitals and the Heart Institute of Abidjan over 10 years. The epidemiologic Data concerned the Parturients, the annual frequency of congenital abnormalities. Distribution of the congenital abnormalities according to the organs, overall mortality and lethality of congenital abnormalities were evaluated. Results: Over 10 years, 1.632 newborns with 1.725 congenital anomalies were recorded. Frequency was 172.5 congenital anomalies per annum. Parturients were less than 35 years in 33% of cases, multigravida in 20%, multiparous in 18% and had a low socio economic status in 96% of cases. Prenatal diagnosis of congenital anomalies was performed in 1.5%. Congenital anomalies were orthopedic in 34%, neurological in 17%, gastrointestinal in 15%, facial in 11.5%, parietal in 13%, urogenital in 9% and cardiac in 0.5% of cases. The overall mortality rate of congenital anomalies was 52% and gastroschisis was the most lethal disease with 100% mortality. Conclusion: This descriptive study reveals the low socio economic status of Parturients with congenital anomalies and their poor prenatal diagnosis. These factors explain the very high mortality of congenital anomalies due to a delay management in our country in which medical expenses were borne by parents and where technical platforms remain obsoletes for good resuscitation and neonatal surgery.

    Postpartum hemorrhage is the outstanding cause of maternal mortality, and a redoubtable contributor to puerperal death from other causes, notably infection and renal failure. The clinical situations in which hemorrhage is liable to occur must be better known, so that anticipatory and preventive measures can be taken. Recent knowledge about defibrinated blood in women with degenerative changes at the placental site must be incorporated in the thinking and practice of physicians dealing with obstetrical cases. The indications, limitations, and hazards of the various anesthetic methods available for parturient women should be carefully considered in the circumstances of each case.

    The purpose of our research was an analysis of the influence of laserotherapy in the process of treating late gestoses in gravidas, as well as preventing complications following cesarean section. An improvement of the state of the gravida and fetus was detected according to the findings of the disease pattern, coagulogram and cardiotachography. We want to demonstrate the positive effect of laserotherapy which was carried out with the purpose of prophylaxis on the course of the postoperative period in parturients. The results of observations is the following: pyo-septic complications reduced by 14.3%.

    Pseudotumor cerebri syndrome (PTCS) is a rare disorder chiefly observed in obese women of childbearing age. We describe a case of a parturient with PTCS managed successfully with an intrathecal catheter, after inadvertent dural puncture, for labor analgesia, surgical anesthesia, and treatment of headache because of intracranial hypertension during the peripartum period. Prolonged placement of the intrathecal catheter (i.e., >24 hours) may have contributed to the absence of postdural puncture headache symptoms and an uneventful postpartum period. Intrathecal catheter placement may therefore be a viable option in patients with PTCS should inadvertent dural puncture occur. PMID:26825990

    Acute respiratory distress syndrome (ARDS) is an uncommon condition in pregnant patients. The causes of ARDS are associated with obstetric causes such as amniotic fluid embolism, preeclampsia, septic abortion, and retained products of conception or nonobstetric causes that include sepsis, aspiration pneumonitis, influenza pneumonia, blood transfusions, and trauma. An essential component in management of ARDS involves good communication between the obstetrics team and critical care specialist and a fundamental understanding of mechanical ventilatory support. Medical therapies such as nitric oxide and corticosteroids play a complimentary role. Extracorporeal life support is beneficial in the management of the parturient with severe ARDS. PMID:25314088

    Although the roles of the intrapartum nurse and professional doula differ markedly, they serve women best if their roles complement each other. For doulas and nurses to work well together in order to facilitate a positive birth experience for the patient, they would logically need to develop a relationship based on mutual respect. The purpose of this pilot qualitative study was to examine the level of acceptance shown by intrapartum nurses for doula support, as perceived by the parturient woman. Implications for further research are addressed. PMID:17322940

    The efficacies of vitamin D3 and its 1-alpha hydroxyl derivative (1-alpha) in controlling clinical milk fever, hypocalcaemia and hypophosphataemia in parturient cows have been compared. A corticosteroid was used in some cases to optimise and control the interval between prophylactic treatment and parturition. Our observations suggest that the combination of 1-alpha and corticosteroid was particularly valuable and could be used in the development of a successful prophylactic regime. This conclusion is supported by both clinical and biochemical measurements. PMID:6255674

    2013-09-01

    Spinal anesthesia is widely regarded as a reasonable anesthetic option for cesarean delivery in severe preeclampsia, provided there is no indwelling epidural catheter or contraindication to neuraxial anesthesia. Compared with healthy parturients, those with severe preeclampsia experience less frequent, less severe spinal-induced hypotension. In severe preeclampsia, spinal anesthesia may cause a higher incidence of hypotension than epidural anesthesia; however, this hypotension is typically easily treated and short lived and has not been linked to clinically significant differences in outcomes. In this review, we describe the advantages and limitations of spinal anesthesia in the setting of severe preeclampsia and the evidence guiding intraoperative hemodynamic management. PMID:23868886

    The morbidity rates, ++features of lactation formation, and serum and breast milk lysozyme levels were studied in 91 parturients who showed various breast functional activity in the early postpartum period. The highest frequency of postpartum ++pyo-septic diseases was found in females with hyperlactation. There was earlier appearance of foremilk and milk in these females. Healthy mothers with higher breast functional activity exhibited the greatest levels of lysozyme in the milk and marked decreases in its levels in the blood within the first 3 days as compared to those observed in females who had normal or insufficient quantities of milk.

    A 37-year-old parturient underwent emergency cesarean delivery because of severe preeclampsia. After induction of general anesthesia, the oxygen saturation decreased. Volatile anesthetics were discontinued and examination of the anesthetic circuit and machine revealed a soda lime canister that was extremely hot. The patient was detached from the anesthetic machine and hand-ventilated with an external oxygen cylinder. The surgery was cancelled and the patient was extubated. Analysis of the cylinder connected to the anesthesia machine displayed 100% carbon dioxide. The patient developed progressive respiratory failure. Bronchoscopic examination revealed burn scars from the carina to the main bronchi. The patient died within four months of the incident. PMID:19734035

    The number of caesarean sections has increased over the last two decades, especially in the developed countries. Hence, it has increasingly become a greater challenge to provide care for the parturient, but this has given obstetric anaesthetists a greater opportunity to contribute to obstetric services. While caesarean deliveries were historically performed using general anaesthesia, there is a recent significant move towards regional anaesthesia. Unique problems that patients with obesity and pre-eclampsia present will be discussed in the present article. New medications and devices now used in obstetric anaesthesia will change the practice and perspectives of our clinical practice. PMID:21189878

    Investigation of the age dependent single-dose radiation tolerance, latency to radiation myelopathy, and the histopathological changes after irradiation of the rat cervical spinal cord is presented. Rats were irradiated with graded single doses of 4 MV photons to the cervical spinal cord. When the rats showed definite signs of paresis of the forelegs, they were killed and processed for histological examination. The radiation dose resulting in paresis due to white matter damage in 50% of the animals (ED[sub 50]) after single dose irradiation was about 21.5 Gy at all ages [ge] 2 weeks. Only the Ed[sub 50] at 1 week was significantly lower. The latency to the development of paresis clearly changed with the age at irradiation, from about 2 weeks after irradiation at 1 week to 6-8 months after irradiation at age [ge] 8 weeks. The white matter damage was similar in all symptomatic animals studied. The most prominent were areas with diffuse demyelination and swollen axons, often with focal necrosis, accompanied by glial reaction. This was observed in all symptomatic animals, irrespective of the age at irradiation. Expression of vascular damage appeared to depend on the age at irradiation. Although the latency to myelopathy is clearly age dependent, single dose tolerance is not age dependent at age [ge] 2 weeks in the rat cervical spinal cord. The white matter damage is similar in all symptomatic animals studied, but the vasculopathies appear to be influenced by the age at irradiation. It is concluded that white matter damage and vascular damage are separate phenomena contributing to the development of radiation myelopathy, expression of which may depend on the radiation dose applied and the age at irradiation. 28 refs., 5 figs., 3 tabs.

    A 28-month-old African hedgehog was referred to our hospital with progressive tetraparesis. On the first presentation, the hedgehog was suspected as having wobbly hedgehog syndrome (WHS) and the animal was treated with medication and rehabilitation. The animal died 22 days after onset. Pathological examination revealed that the animal was involved in astrocytoma between the medulla oblongata and the spinal cord (C1). This report indicates that a primary central nervous system tumor should be considered as one of the differential diagnoses for hedgehogs presenting with progressive paresis, together with WHS.

    Pineal cyst apoplexy is a very rare entity with previously reported symptoms of severe frontal or occipital headache, gaze paresis and visual field defects, nausea or vomiting, syncope, ataxia, hearing loss and sudden death. The treatment options for symptomatic pineal cysts are observation, shunting, aspiration via stereotactic guidance or endoscopy, third ventriculostomy, ventriculocysternostomy, and/or surgical resection by craniotomy and microsurgery. Here, the authors report an unusual case of a 28-year-old male patient with pineal cyst apoplexy, presenting with headache, insomnia, and sexual dysfunction symptoms who is being managed conservatively and observed for two years by an academic tertiary care unit.

    Neurogenic compromise of vocal fold function exists along a continuum encompassing vocal cord hypomobility (paresis) to vocal fold immobility (paralysis) with varying degrees and patterns of reinnervation. Vocal fold paralysis (VFP) may result from injury to the vagus or the recurrent laryngeal nerves anywhere along their course from the brainstem to the larynx. In this article, we review the anatomy of the vagus and recurrent laryngeal nerves and examine the various etiologies of VFP. Selected cases are presented with discussion of key imaging features of VFP including radiologic findings specific to central vagal neuropathy and peripheral recurrent nerve paralysis. PMID:23814687

    Thyrotoxic hypokalemic periodic paralysis (THPP) is an endocrine emergency marked by recurrent attacks of muscle weakness associated with hypokalemia and thyrotoxicosis. Asiatic male patients are most often affected. On the other hand, African descents rarely present this disease. The case described shows an afrodescendant patient with hypokalemia and tetraparesis, whose diagnosis of hyperthyroidism was considered during this crisis. The THPP, although rare, is potentially lethal. Therefore, in cases of flaccid paresis crisis this diagnosis should always be considered, especially if associated with hypokalemia. In this situation, if no previous diagnosis of hyperthyroidism, this should also be regarded. PMID:25372590

    A 13-year old boy with acute lymphoblastic leukemia had bilateral paresis of the upper extremities and aphasia 1 week after high dose methotrexate and triple intrathecal therapy (methotrexate, cytarabin, hydrocortisone). The stroke-like neurological symptoms disappeared on the third day. T2-weighted magnetic resonance imaging showed hyperintensities of white matter on the second day. Despite resolution of the neurological symptoms, magnetic resonance images were still abnormal 3 years after the attack. Methotrexate has been considered to be responsible for ischemic damage to oligodendroglial cells, resulting in demyelination. The changes are occasionally prolonged without persistent neurologic symptoms. PMID:16247223

This is the first description of comprehensive neuropsychological assessment in a child with this syndrome. The results reflect significant impairments in auditory processing and independent learning and retention, but relatively preserved cognitive performance on interactive tasks involving frequent feedback and redirection.

These are congenital disorders where the primary findings are non-progressive and are caused by developmental abnormalities of cranial nerves/nuclei with primary or secondary dysinnervation. Several CCDD genes have been found, which enhance our understanding of the mechanisms involved in brain stem development and axonal guidance. PMID:25633065

    Strokes are a leading cause of disability, immobility, and reduced ability to perform activities of daily living (ADLs) among the elderly. Balance and postural control are often affected in stroke patients. Physical therapy for the lower back to improve posture, mobility, and ADLs can be very time consuming. In this randomized, controlled study of 66 geriatric patients (mean age 74.5 years) with stroke-related paresis or hemiplegia, it was demonstrated that stroke patients may benefit more from 3 additional weeks of combined whole body vibration and balance training than from a comprehensive inpatient geriatric rehabilitation program in terms of trunk stability, postural control, and muscle tone.

    Laryngeal schwannomas are rare, benign tumors, most often arising from the superior laryngeal nerve. We describe a case of a 68-year-old female with a laryngeal schwannoma of the recurrent laryngeal nerve after traumatic injury. We postulate that trauma to the recurrent laryngeal nerve during thyroidectomy or thyroplasty incited growth of a nerve sheath tumor. This is the first reported case of a trauma-induced schwannoma of the recurrent laryngeal nerve and second case of a recurrent laryngeal nerve schwannoma. Although rare, this case demonstrates that these tumors should be considered during workup of vocal cord paresis after surgery or failed thyroplasty. Laryngoscope, 126:1408-1410, 2016. PMID:26421595

    A 34-year-old diabetic patient underwent a renal transplant which was complicated by right side lower extremity paresis and numbness with gluteal necrosis. The main reason was ligation of internal iliac artery of the same side as a result of extensive microvascular obstruction due to severe atheromatous plaque. This is a rare complication which is mostly reported in aneurysmal patients after bypass surgery. The gluteal necrosis is a serious complication which, as in our patient, resulted in patient's death in most of the reported cases. Because of catastrophic nature of this condition, identifying preventive measures is extremely important. PMID:26793402

The phoniatric management of these cases involved: New functional and acoustic pattern, recorded by the patient as a form of daily maintenance; Laryngeal and perilaryngeal manual therapy, applied according to the "osteovox" method. Manual therapy and different phonatory habits, in association with alternative medicine can reduce the time to recovery in the case of cold-induced unilateral paresis. PMID:23074827

    The upper trunk of the brachial plexus is the most common area affected by neuralgic amyotrophy (NA), and paresis of the shoulder girdle muscle is the most prevalent manifestation. Posterior interosseous nerve palsy is a rare presentation in patients with NA.

    PubMed

    Axelsson, S

    1991-12-01

    Before the onset of bovine paresis a stage of hyperactivity and hypersensitivity was observed in clinical as well as in immunologically provoked cases. By gas chromatographic analysis of choline (Ch) in plasma and serum from four immunologically provoked cows this stage was verified to be an initial immuno-cholinergic hyperactivation. In the first hour after antigen challenge with 0.5 mg nematode AChE there was a very sharp rise in Ch mainly from agonist-stimulated and phospholipase mediated phosphatidylcholine (PC) breakdown. A secondary massive influx of Ca into cells was mirrored in a 1 mmol/l depression of serum-Ca values during the first hours. The hyperagonism mediated Ca-translocation brought water into cells, resulting in reduced plasma volume. The generally supposed mechanism of secondary, Ca-mediated cell damage and cell death was initiated and sometimes resulted in "Downers" with persisting paralysis. All acetylcholine (ACh)-stimulated parts from CNS to the periphery are irregularly involved explaining the very varied clinical appearance of bovine paresis, and the influence on for instance the autonomous nerve system, adrenals and pancreas. In the experimental group, ACh in plasma showed a sharp fall within the first hour, while there were fairly constant values of serum-ACh in the first four hours, possibly indicating some antibody protection. When paresis was established between 15-28 hours after challenge the general anergetic state was characterised by low ACh-levels. Also in a larger field group ACh-levels were significantly depressed in paretic compared to healthy cows. The unexpected finding in this group was considerably higher levels of ACh and especially Ch in serum compared to plasma. The origin of ACh and Ch had to be blood cells. Preliminary gas chromatographic analysis has confirmed ACh-synthesis by leucocytes and an integrated immuno-cholinergic system of great importance can be anticipated. The general feature of bovine paresis is updated

The operative removal of the growing and displacing fatty tissue which by a (congenital?) dural gap continued in epidural direction indeed resulted in a far-reaching regression of the paresis of the lower extremities, not, however, in an improvement of the urological picture of the disease. The renal insufficiency caused by the hydronephrosis was no more reversible, which emphasizes the importance of the early diagnosis of this relatively infrequent malformation. PMID:3727820

We report the case of a 44 year-old male with cutaneous and severe visceral lesions, paresis and paresthesia of the right upper limb induced by a high energy electrical shock. No psychiatric manifestations were observed. This case followed an unusual course due to the particular evolution of the hepatic lesions, which included necrosis, abscesses, thrombosis and angiocholitis. PMID:24432255

    Ewing sarcoma is a malignant tumour of the bone that sometimes presents extraskeletal involvement, with the epidural location being rare. We report the case of a 45-year-old woman with paresthesia, paresis and urinary retention. Magnetic resonance imaging showed an epidural mass from C6 to D3. Laminectomy from C7 to D2 and partial resection of the lesion was performed. Pathological analysis was consistent with Ewing sarcoma. The patient received chemotherapy and radiotherapy, without evidence of disease at 8 months follow-up. A review of the literature on all published cases of extraskeletal Ewing sarcoma with epidural involvement is presented. PMID:25497289

    A 33-year-old man presented with moderate low-back pain and L-5 radiculopathy that progressed to severe paresis of L-5. On initial imaging, a corresponding spinal lesion was overlooked. Further CT and contrast-enhanced MRI demonstrated a presacral mass along the L-5 root far extraforaminally. A herniated disc was suspected, but with standard imaging a schwannoma could not be ruled out. The presacral L-5 root was explored via a microsurgical lateral extraforaminal transmuscular approach. To the best of the authors' knowledge, there have been no reports of sequestered extraforaminal lumbosacral disc herniations that herniated into the presacral region. PMID:26637061

    Pure intramedullary spinal-cord metastases (ISCM) are a rare manifestation of cancer. We report a case of ISCM from gastric cancer. A 68-year-old man, treated with total gastrectomy for a gastric cancer, presented 9 months later with paresis of the left arm, pain and dissociated sensory loss. Magnetic resonance imaging revealed a pure intramedullary lesion at the C3-C5 level. After surgical resection, pathological findings revealed an undifferentiated adenocarcinoma of gastric origin. To our knowledge, this is only the second report of ISCM from gastric cancer in the literature. PMID:16465555

    Flaccid nonambulatory tetraparesis or tetraplegia is an infrequent neurologic presentation; it is characteristic of neuromuscular disease (lower motor neuron [LMN] disease) rather than spinal cord disease. Paresis beginning in the pelvic limbs and progressing to the thoracic limbs resulting in flaccid tetraparesis or tetraplegia within 24 to 72 hours is a common presentation of peripheral nerve or neuromuscular junction disease. Complete body flaccidity develops with severe decrease or complete loss of spinal reflexes in pelvic and thoracic limbs. Animals with acute generalized LMN tetraparesis commonly show severe motor dysfunction in all limbs and severe generalized weakness in all muscles. PMID:25441630

    Cerebrovascular accidents (CVA) and spinal cord injuries (SCI) are the most common causes of paralysis and paresis with reported prevalence of 12,000 cases per million and 800 cases per million, respectively. Disabilities that follow CVA (hemiplegia) or SCI (paraplegia, tetraplegia) severely impair motor functions (e.g., standing, walking, reaching and grasping) and prevent the affected individuals from healthy-like, full and autonomous participation in daily activities. Our research focuses on the development of a new virtual reality (VR) system combined with wearable neurorobotics (NR), motor-neuroprosthetics (MNP) and brain neuro-machine interface (BNMI) to overcome the major limitations of current rehabilitation solutions.

    Intraoperative management of a known acute intermittent porphyria patient is a challenge requiring awareness of factors, which trigger an acute crisis, clinical features of a porphyric attack, knowledge of safe pharmacologic intervention, and preparedness for reintubation and ventilatory support. The classical signs of a porphyric crisis such as pain abdomen, vomiting and neuropsychiatric symptoms are masked under general anesthesia and can be confused with postoperative pain and vomiting and postoperative cognitive dysfunction, especially for intra-abdominal surgeries. Eternal vigilance for onset of an acute crisis is imperative. After a crisis of acute intermittent porphyria, residual paresis may persist for years in the absence of further attacks. PMID:25558204

    Upper-arm non-invasive blood pressure measurement during caesarean section can be uncomfortable and unreliable because of movement artefact in the conscious parturient. We aimed to determine whether ankle blood pressure measurement could be used instead in this patient group by comparing concurrent arm and ankle blood pressure measured throughout elective caesarean section under regional anaesthesia in 64 term parturients. Bland-Altman analysis of mean difference (95% limits of agreement [range]) between the ankle and arm was 11.2 (-20.3 to +42.7 [-67 to +102]) mmHg for systolic arterial pressure, -0.5 (-21.0 to +19.9 [-44 to +91]) mmHg for mean arterial pressure and -3.8 (-25.3 to +17.8 [-41 to +94]) mmHg for diastolic arterial pressure. Although ankle blood pressure measurement is well tolerated and allows greater mobility of the arms than measurement from the arm, the degree of discrepancy between the two sites is unacceptable to allow routine use of ankle blood pressure measurement, especially for systolic arterial pressure. However, ankle blood pressure measurement may be a useful alternative in situations where arm blood pressure measurement is difficult or impossible. PMID:23480469

    Objective. We aimed to evaluate the impact of an intensified anticipatory guidance program in the nursery on Emergency Department (ED) use for nonurgent conditions (NUCs) in the neonatal period. Methods. Parturient mothers of healthy newborns were randomized to an intervention group or control group. Baseline and 1-month follow-up knowledge surveys regarding newborn care were conducted. The primary outcome was the proportion of neonates who used the ED for a NUC. Secondary outcome was change in caregivers' knowledge on NUC. Results. Of a total of 594 mothers, 323 (54%) agreed to participate and were randomized to intervention (n = 170) or control (n = 153) group. Most were Hispanic (68%), single (61%), primiparous (39%), and without high school diploma (44%). 35 (21%) neonates in the intervention group and 41 (27%) in the control group were brought at least once for a NUC to the ED (p = 0.12). There was no statistically significant difference in within subject change on knowledge scores between the two study arms. Conclusions. Neonatal ED visits for NUCs occur frequently. This nursery-based intensified anticipatory guidance program had no statistically significant impact on neonatal ED use for NUC, nor on neonatal care-relevant knowledge among parturient mothers. Alternative modalities and timing of parental educational intervention may need to be considered. This trial is registered with Clinical Trials Number NCT01859065 (Clinicaltrials.gov). PMID:27212955

    Background and Aims: Ropivacaine is considered as a safe alternative to bupivacaine for labor analgesia. The aim was to compare epidural ropivacaine and bupivacaine in intermittent doses for obstetric analgesia. Material and Methods: In this prospective, randomized, double-blind study, 60 women in labor were randomly allocated to receive either bupivacaine 0.1% with fentanyl 2 μg/mL (BF), or ropivacaine 0.1% with fentanyl 2 μg/mL (RF). Bromage scale, loss of cold sensation to ether swab in midclavicular line, visual analog scale were used to test for motor block, sensory block and pain, respectively. Hemodynamic parameters, onset of analgesia, dose requirement of drug to produce analgesia, duration of labor, and incidence of side effects were also recorded. Data were expressed as mean ± standard deviation and analyzed using students unpaired t-test, Chi-square and Mann-Whitney U-tests at P < 0.05. Results: Both drugs were similar with respect to hemodynamic stability, onset of analgesia, quality of analgesia, sensory blockade, neonatal outcome, requirement of drugs, duration of labor, and incidence of side effects. Three parturient in bupivacaine (B-F) group had a motor block of Bromage 1 and were delivered using forceps. None of the parturient in ropivacaine (R-F) group had any motor block, and all had spontaneous vaginal delivery, but this difference was not statistically significant (P = 0.081). Conclusions: Bupivacaine and ropivacaine provide equivalent analgesia in low (0.1%) concentration. PMID:27006539

    There is some concern that providing parturients with epidural analgesia increases the likelihood of cesarean delivery. Because of the widespread interest in cesarean rates and the expanding use of epidural analgesia, we believed that this contention should be assessed. Hospital records were reviewed to determine the primary cesarean rate for 1084 parturients who delivered at our institution during 15 months in which there was a 24-hour "on demand" epidural service. This was compared with our primary cesarean rate during 15 months in which epidural analgesia was not available, even on physician request. Because of the characteristics of our institution, this control group consisted of patients from the same population base managed by the same eight obstetricians using the same management techniques. For patients in labor, the primary cesarean rate overall was 9.0% before and 8.2% after the epidural service began (P = .626). When subpopulations based on parity and indication for cesarean delivery were studied, there were no significant changes in the cesarean rate. These results demonstrate that the availability of on-demand epidural analgesia for patients in labor did not increase the primary cesarean rate, either in the aggregate or for any of the subpopulations studied.

    Purpose To observe the hemodynamic changes of parturients in the combined use of hyperbaric (4 mg) and hypobaric (6 mg) ropivacaine during spinal anesthesia for caesarean section in this randomized double-blind study. Methods Parturients (n = 136) undergoing elective cesarean delivery were randomly and equally allocated to receive either combined hyperbaric and hypobaric ropivacaine (Group A) or hyperbaric ropivacaine (Group B). Outcome measures were: hemodynamic characteristics, maximum height of sensory block, time to achieve T8 sensory blockade level, incidence of complications, Apgar scores at 1 and 5 min, and neonatal blood gas analysis. Results Group A had a lower level of sensory blockade (T6 [T6-T7]) and longer time to achieve T8 sensory blockade level (8 ± 1.3 min) than did patients in Group B (T3 [T2-T4] and 5 ± 1.0 min, respectively; P < 0.001, both). The incidence rates for hypotension, nausea, and vomiting were significantly lower in Group A (13%, 10%, and 3%, respectively) than Group B (66%, 31%, and 13%; P < 0.001, P = 0.003, P = 0.028). Conclusions Combined use of hyperbaric (4 mg) and hypobaric (6 mg) ropivacaine significantly decreased the incidences of hypotension and complications in spinal anesthesia for caesarean section by extending induction time and decreasing the level of sensory blockade.

    In a prospective, double-blind, randomised controlled trial, we compared the efficacy of patient-controlled analgesia using remifentanil (25-30 μg per bolus) with intramuscular pethidine (50-75 mg) for labour analgesia in 69 parturients. Parturients receiving patient-controlled analgesia reported less pain than those receiving intramuscular pethidine throughout the study period (p < 0.001), with maximal reduction in visual analogue pain score at 2 h after commencement of analgesia (mean (SD) 20 (17) in the patient-controlled analgesia group and 36 (22) in the intramuscular pethidine group. The median (95% CI) time to the first request for rescue analgesics was significantly longer with patient-controlled analgesia (8.0 (6.8-9.2) h) compared with intramuscular pethidine (4.9 (3.8-5.4) h, p < 0.001). Maternal satisfaction scores were also higher with remifentanil compared with intramuscular pethidine (p= 0.001). There was no report of sedation, aponea or oxygen desaturation in either group, and Apgar scores were similar between groups. We conclude that patient-controlled analgesia with remifentanil provides better labour analgesia and maternal satisfaction than intramuscular pethidine. At this dose, maternal and fetal side effects were uncommon. PMID:21707564

    Background and Aim: Nausea and vomiting causes distress to patients and increases surgical complications. Though various antiemetics are available, their effectiveness and fetal safety profile when used in parturient remains debatable. This randomized, double-blind, comparative study was designed with an aim to compare the antiemetic effects of ondansetron and glycopyrrolate during cesarean section. Methods: Sixty-six parturients (American Society of Anesthesiologist physical status I-II) scheduled for elective cesarean section were randomized to receive intravenous ondansetron 4 mg (Group O, n = 32) or glycopyrrolate 0.2 mg (Group G, n = 31) before spinal anesthesia. Outcome measures studied were emesis, episodes of hypotension and bradycardia and pain, till 10 h postoperative. Statistical software used was Epi Info 7 and Microsoft Excel. Results: There was no significant difference in nausea and vomiting at all the study intervals between the two groups statistically. There was no difference in episodes of hypotension, but episodes of bradycardia were significantly less in glycopyrrolate group (26%) than in ondansetron group (56%) (P = 0.027). There was no difference in additional analgesic requirements. However, the incidence of dry mouth was significantly greater in glycopyrrolate group (21 [68%]) as compared to ondansetron group (5 [16%]) (P = 0.00). Conclusion: Effect of glycopyrrolate on nausea and vomiting during cesarean section are comparable to ondansetron, but with an increased incidence of dry mouth. Glycopyrrolate has no effect on hypotension or additional analgesic requirements, but the incidence of bradycardia is significantly less. PMID:26712972

    Rapid HIV test in labour provide an opportunity for the identification of HIV positive pregnant women who should benefit from interventions to reduce the risk of mother-to-child transmission (MTCT) of HIV. Between November 2013 and June 2014 we conducted rapid HIV testing of pregnant women in labour at the National Hospital Abuja to determine the HIV seroconversion rate in pregnancy and the prevalence of HIV in pregnant women in labour with previously unknown status. HIV testing and counseling (HTC) was acceptable to 224 (99.6%) of the pregnant women who met the study criteria. The mean 'turnaround' time for test result was 288 minutes and 16.2 minutes for tests performed in the hospital laboratory and those performed at the point-of-care (labour ward) respectively. HIV seroconversion was detected in 2(1.2%) of the 165 parturients with initial HIV negative result early in the index pregnancy. HIV infection was detected in four (2.7%) of the 59 parturients with unknown HIV status. Secondary school level education was significantly associated with HIV seroconversion in pregnancy P < 0.001. HTC in labour using rapid testing strategy is feasible and acceptable in our setting. The introduction of HCT will lead to the diagnosis of HIV positive women in labour, appropriate interventions and prevention of MTCT of HIV. PMID:26897922

    Caffeine has been demonstrated to have a protective effect on neonatal viability of piglets. In order to assess whether caffeine, administered to parturient sows, also affects maternal behaviour, respiratory rate, and dopamine, nitric oxide and serotonin plasma levels, 20 sows, with induced parturition, received orally 27mg/kg of body weight of caffeine (T group; n=10) or not (NT group; n=10), on day 113 of gestation. Treatment did not affect the farrowing length. There were less stillborn piglets in T group than NT group (0.67 vs 2.44; P<0.05), whereas no differences in dead piglets at 24h from birth was observed. Caffeine did not affect physiological parameters of sows, as the behaviour score of sows laying on belly was reduced (P<0.05). In conclusion, although the present study was carried out with a limited number of sows, administration of caffeine to parturient sows has the potential for reducing the number of stillborn.

    The objective was to identify suitable enzyme immunoassays to monitor gonadal and placental function in the female polar bear. Immunoreactive progesterone, progesterone metabolite (PdG), estrogen, and androgen metabolite (T) concentrations were measured in fecal samples collected over 24 mo from captive female bears (N = 20). Whereas fecal extracts produced displacement curves parallel to the standard curve for each respective steroid, T and PdG more accurately reflected reproductive events. Concentrations of fecal T increased (P < 0.05) during the breeding season, and brief spikes were associated with estrus and mating. A postovulatory increase in PdG was not always detected, but sustained baseline T after mating appeared consistent with ovulation. Parturient bears excreted higher PdG concentrations (P < 0.05) during expected time of embryo implantation in Fall, and a late gestational rise in fecal T occurred 30 days prepartum. Many nonparturient bears also had a PdG rise in the Fall, suggesting they experienced either pregnancy loss or a pseudopregnancy. Differentiating pregnant and pseudopregnant states was not achieved using fecal PdG alone, but when combined with fecal T, comprehensive diagnoses could be made. Nonparturient bears demonstrated elevated (P < 0.05) fecal T during summer months, whereas parturient bears did not. In summary, noninvasive hormone monitoring techniques were established for the female polar bear. Although this study was directed at facilitating management and breeding efforts of captive polar bears, the methods could be applied to studies of reproductive function in wild populations.

    Parturition is one of the most important yet least observed events in studies of primate life history and reproduction. Here, I report the first documented observation of a bonobo (Pan paniscus) birth event in the wild, at the Luikotale Bonobo Project field site, Democratic Republic of the Congo. The nulliparous mother's behaviour before, during and after parturition is described, along with reactions of other community members to the birth and the neonate. Data were collected through focal-animal observations, and the events postpartum were photo-documented. The behaviour and spatial distribution of party members were recorded using scan samples. Parturition occurred during the late morning in a social context, with parous females in close proximity to the parturient mother. Placentophagia occurred immediately after delivery, and the parturient shared the placenta with two of the attending females. I compare this observation with reports of parturition in captive bonobos, and highlight the observed female sociality and social support during the birth event. Plausible adaptive advantages of parturition occurring in a social context are discussed, and accrued observations of birth events in wild and free-ranging primates suggest that females may give birth within proximity of others more frequently than previously thought. This account contributes rare empirical data for examining the interface between female sociality and parturition, and the evolution of parturitional behaviours in primates. PMID:25007717

    PubMed

    Okutomi, Toshiyuki; Kato, Rie

    2011-07-01

    Preoperative oral hydration is an important component of "enhanced recovery after surgery" strategies. This was originally developed for patients undergoing colon surgery. The Obstetric Anesthesia Practice Guideline issued by American Society of Anesthesiologists states that intake of minimum amount of clear fluid 2 hours prior to surgery may be safe. However, anesthesiologists have to consider physiological changes that parturients undergo during pregnancy, such as increased risk of aspiration and impaired glucose tolerance. We also have to consider the potential effect of glucose loading on neonates. Mothers are more likely to develop ketosis by glucose loading. It also stimulates insulin release in the fetus, which can result in neonatal hypoglycemia. In addition, sodium overloading may deteriorate intra-vascular dehydration and cause lung edema to mothers. On the other hand, oral hydration can alleviate a sense of thirst and increase maternal satisfaction. Our data showed that maternal urinal ketone body at delivery tended to decrease with oral hydration during labor. Moreover, some articles suggest that oral hydration may improve utero-placental perfusion. Therefore, we have to balance risks and benefits of oral hydration in parturients. Further investigations are needed among this specific subgroup of patients in order to establish the safe application of preoperative oral hydration. PMID:21800658

    2015-02-28

    This review article summarises the many reports in the literature, confirming that, in sheep, parasitic infections can adversely affect reproductive efficiency; examples, which refer to all parts of the reproductive cycle of sheep, are as follows: trichostrongylosis in ewe-lambs (which can lead to delayed attainment of puberty), myiosis of the prepuce (which can cause impediment of mating), chorioptic mange or trypanosomosis in rams (which can lead to testicular degeneration or azoospermia, respectively), trypanosomosis or sarcoptic mange in pre-conceptual ewes (which can lead to poor conception rates or reduced number of ovulations, respectively), toxoplasmosis or neosporosis in pregnant ewes (which are causes of abortion), trichostrongylosis or trematode infections in lactating ewes (which can cause reduction of milk yield and can be a risk factor for mastitis, respectively), cryptosporidiosis in newborn lambs (which can be a cause of deaths), coccidiosis in growing pre-weaned lambs (which can cause suboptimal growth rate). In other cases, the reproductive status of the animal can influence the parasitic infection; examples are as follows: the increase in faecal parasitic output during the peri-parturient period (as a consequence of the peri-parturient relaxation of immunity), the heavier trichostrongylid infections of twin lambs compared to lambs from single parities (as a consequence of developmental origin issues in twin lambs). All the above examples support the idea of presence of interactions between parasitic infections and reproductive efficiency in sheep. PMID:25577675

    In transcervical resection of the submandibular gland for benign lesions, only a limited risk of damage to neural structures can be accepted and a cosmetically satisfactory result is mandatory. In this retrospective case series, we evaluated 139 patients operated over a 10-year period and completed long-term clinical follow-up of 113 of these patients after a median of 81 months. In all patients, the operation was effective. We found a 4.3 % risk of reoperation for wound infection or postoperative hematomas and an 18.7 % risk of early paresis of the marginal branch of the facial nerve, which decreased to 2.7 % on long-term follow-up. We found a 4.4 % risk of permanent lingual nerve paresis, and no patients had damage to the hypoglossal nerve. Xerostomia was found in 22.1 % of the patients and could be quantified by the easily performed biscuit test. Only 2.5 % reported an unsatisfactory cosmetic result and all scars were ≤ 6 on the Vancouver Scar Scale. Problems with scarring were more common if there had been postoperative infection. We continue to use the lateral transcervical approach as standard in our institution for patients who cannot be managed by gland-sparing procedures. PMID:22941392

    Study Design Case series of two arytenoid dislocations after anterior cervical discectomy. Objective To recognize arytenoid dislocation as a possible cause of prolonged hoarseness in patients after anterior cervical discectomies. Summary of Background Data Prolonged hoarseness is a common postoperative complication after anterior cervical spine surgery. The etiology of prolonged postoperative hoarseness is usually related to a paresis of the recurrent laryngeal nerve. However, other causes of postoperative hoarseness may be overlooked in this clinical scenario. Other possible etiologies include pharyngeal and laryngeal trauma, hematoma and edema, injury of the superior laryngeal nerve, as well as arytenoid cartilage dislocation. Arytenoid dislocation is often misdiagnosed as vocal fold paresis due to recurrent or laryngeal nerve injury. Methods We report two cases of arytenoid dislocation and review the literature on this pathology. Results Two patients treated with anterior cervical discectomy and fusion experienced prolonged postoperative hoarseness. Arytenoid dislocation was confirmed by flexible fiber-optic laryngoscopy in both cases. The dislocations experienced spontaneous reduction at 6 weeks and 3 months postsurgery. Conclusions Arytenoid dislocation must be considered in the differential diagnosis of prolonged postoperative hoarseness and evaluated for using direct laryngoscopy, computed tomography, or a laryngeal electromyography. Upon diagnosis, treatment must be considered immediately. Slight dislocations can reduce spontaneously without surgical intervention; however, operative intervention may be required at times.

  13. The influence of functional electrical stimulation on hand motor recovery in stroke patients: a review

    PubMed Central

    2014-01-01

    Neuromuscular stimulation has been used as one potential rehabilitative treatment option to restore motor function and improve recovery in patients with paresis. Especially stroke patients who often regain only limited hand function would greatly benefit from a therapy that enhances recovery and restores movement. Multiple studies investigated the effect of functional electrical stimulation on hand paresis, the results however are inconsistent. Here we review the current literature on functional electrical stimulation on hand motor recovery in stroke patients. We discuss the impact of different parameters such as stage after stoke, degree of impairment, spasticity and treatment protocols on the functional outcome. Importantly, we outline the results from recent studies investigating the cortical effects elicited by functional electrical stimulation giving insights into the underlying mechanisms responsible for long-term treatment effects. Bringing together the findings from present research it becomes clear that both, treatment outcomes as well as the neurophysiologic mechanisms causing functional recovery, vary depending on patient characteristics. In order to develop unified treatment guidelines it is essential to conduct homogenous studies assessing the impact of different parameters on rehabilitative success. PMID:25276333

    Background: Primary intraosseous cavernous hemangiomas (PICH) of the skull represent an infrequent bone tumor. Although some rare cases of PICHs located in the skull base have been published, to our concern only three cases have been reported in the English literature of PICHs arising within the clivus. Case Description: We present the case of a patient presenting an isolated abducens paresis due to a rare PICH of the clivus showing also an unusual destruction of the inner table as well as infiltration of the dura mater. Due to this uncommon infiltrative pattern of an otherwise expected intraosseous tumor, a cerebrospinal fluid (CSF)-fistula occurred while performing a transnasal biopsy. The patient recovered successfully without need of lumbar drainage or re-surgery. Additionally, intratumoral decompression was sufficient to relief the abducens paresis. Conclusions: Our case provides new and meaningful information about clinical features as well as growth pattern of these rare clival tumors. We also discuss the importance of knowing these peculiarities before surgery in order to plan the optimal operative management as well as to avoid complications while approaching PICHs localized in such a delicate cranial region.

    Selective dorsal rhizotomy (SDR) surgery is a well-established treatment for ambulatory children with bilateral spastic paresis and is performed to eliminate spasticity and improve walking. The objective of this case report is to describe sudden falls as a persistent complication of SDR. The authors report on 3 patients with bilateral spastic paresis, aged 12, 6, and 7 years at the time of surgery. The percentage of transected dorsal rootlets was around 40% at the L2-S1 levels. Sudden falls were reported with a frequency of several a day, continuing for years after SDR. The falls were often triggered by performing dual tasks as well as occurring in the transition from sitting to standing, during running, after strenuous exercise, or following a fright. Patients also had residual hyperesthesia and dysesthesia of the foot sole. The authors hypothesize that the sudden falls are caused by a muscle inhibition reflex of the muscles in the legs, as an abnormal reaction to a sensory stimulus that is perceived with increased intensity by a patient with hyperesthesia. A favorable effect of gabapentin medication supports this hypothesis. PMID:27104630

    Ventriculoperitoneal (VP) shunt surgery is probably the commonest surgical procedure in neurosurgery. Belying its technical simplicity is the myriad complications associated with it. Shunt malfunction is a common complication associated with this surgery, second only to shunt related infections, which may be associated with it. Sterile cerebrospinal fluid (CSF) eosinophilia (CE) has been reported with VP shunts, which may or may not be related to the dysfunction. Eosinophilia in the CSF has also been associated with a number of other conditions including parasitic infestations in the brain. This may be unrelated to the shunt surgery. We present a case of a child, operated earlier for hydrocephalus, who presented with sub-acute loss of vision and bilateral oculomotor paresis. CSF from a chamber tap revealed eosinophilia. The commonest presenting symptom of shunt malfunction is raised intracranial pressure. There are no reports in the literature of VP shunt malfunction presenting with bilateral oculomotor paresis and decreased visual acuity. The associated CE complicated the clinical picture, especially since the initial brain radiology was normal. We discuss the clinical differential diagnosis of this very interesting presentation, management dilemmas and outcome in this child. This rare clinical presentation was found to be the result of a shunt malfunction and not due to any rare parasitic infestation of the brain. Occam's razor dictates that the simplest explanation in a given situation is usually the most accurate, as is seen in this case. PMID:25972962

    The present work aims at demonstrating that a customised choice of shape memory alloy (SMA) composition, thermo-mechanical treatment and shaping can lead to effective rehabilitation devices applicable to sub-acute and chronic spastic paresis in paediatric patients. SMA pseudoelasticity is regarded as a means to implement a corrective action on posture without hindering residual voluntary or reflex mobility of the affected limb. Specific hinges containing NiTi or NiTiNb elements were designed and constructed to transfer pseudoelastic recovery force to fitted splints for the elbow or the ankle joint. The devices were mechanically tested and showed complete stability after 20-100 cycles, and unchanged characteristics after 1000 full-range deflections. Repositioning splints equipped with patient-specific pseudoelastic hinges were prescribed to 25 individuals (aged 7.75 ± 5.40 years) with mild to severe spastic tetraparesis. Clinical and instrumental evaluations were carried out during crossover trials with traditional and pseudoelastic splints. The sequence of treatment steps was randomized for each subject. The results show that, compared to fixed-angle braces, pseudoelastic devices decrease passive joint stiffness while providing the same control on limb posture. Dynamic pseudoelastic braces are therefore an innovative treatment for spastic paresis, which may reduce joint stiffness. PMID:23793385

    OBJECTIVE To investigate the prevalence and type of laryngeal abnormalities in dogs examined because of cough that did not have signs of upper airway disease and to compare the prevalence of those abnormalities among dogs with various respiratory tract diseases. DESIGN Prospective study. ANIMALS 138 dogs with cough that did not have signs of upper airway disease. PROCEDURES The study was conducted between July 2001 and October 2014 and included dogs examined for cough that had laryngoscopic and bronchoscopic examinations performed by 1 examiner. Laryngeal hyperemia and swelling were recorded, and laryngeal function was assessed before and after doxapram stimulation when indicated. Results were compared among dogs on the basis of cough duration (acute [< 2 weeks], subacute [2 weeks to 2 months], and chronic [> 2 months]) and disease diagnosed (inflammatory airway disease, airway collapse, lower respiratory tract infection, and eosinophilic bronchopneumopathy). RESULTS Laryngeal hyperemia was detected in 73 of 134 (54%) dogs with cough of subacute or chronic duration, and its prevalence did not vary significantly among dogs with various diseases. Thirteen dogs had laryngeal paresis, and 13 dogs had laryngeal paralysis; dysphonia (n = 2) and stridor (1) were uncommon findings in those dogs. The prevalence of laryngeal dysfunction (paresis or paralysis) did not differ significantly among diseases. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that 26 of 138 (19%) dogs examined because of cough alone had laryngeal dysfunction, which suggested that a complete laryngoscopic examination should be included in the diagnostic evaluation of dogs with cough.

    A focal atonic seizure is a partial seizure in which the ictal manifestation consists of paresis of the extremities or muscles on one side of the body, and this phenomenon can easily be misdiagnosed as a transient ischemic attack. An 86-year-old woman visited our hospital complaining of transient right upper extremity weakness lasting for 10 min following an unusual sensation in her chest accompanied by palpitations. On the third hospital day, she again complained of right arm weakness, which progressed to jerky movements of her right extremity accompanied by facial twitching and then generalized into a tonic–clonic seizure. The EEG displayed several interictal spikes in the contralateral temporal area, and the ictal SPECT, analyzed using the SISCOM system, showed an increased signal in both the contralateral superior parietal area and the mesial frontal area. In this case, the patient was diagnosed with focal atonic seizures as the cause of the monolimb weakness, which had been initially misdiagnosed aas transient ischemic attacks. In cases in which a patient presents with monolimb paresis, physicians should consider the possibility of an atonic seizure as the cause. PMID:25870790

  20. Historic evidence to support a causal relationship between spirochetal infections and Alzheimer’s disease

    Following previous observations a statistically significant association between various types of spirochetes and Alzheimer’s disease (AD) fulfilled Hill’s criteria in favor of a causal relationship. If spirochetal infections can indeed cause AD, the pathological and biological hallmarks of AD should also occur in syphilitic dementia. To answer this question, observations and illustrations on the detection of spirochetes in the atrophic form of general paresis, which is known to be associated with slowly progressive dementia, were reviewed and compared with the characteristic pathology of AD. Historic observations and illustrations published in the first half of the 20th Century indeed confirm that the pathological hallmarks, which define AD, are also present in syphilitic dementia. Cortical spirochetal colonies are made up by innumerable tightly spiraled Treponema pallidum spirochetes, which are morphologically indistinguishable from senile plaques, using conventional light microscopy. Local brain amyloidosis also occurs in general paresis and, as in AD, corresponds to amyloid beta. These historic observations enable us to conclude that chronic spirochetal infections can cause dementia and reproduce the defining hallmarks of AD. They represent further evidence in support a causal relationship between various spirochetal infections and AD. They also indicate that local invasion of the brain by these helically shaped bacteria reproduce the filamentous pathology characteristic of AD. Chronic infection by spirochetes, and co-infection with other bacteria and viruses should be included in our current view on the etiology of AD. Prompt action is needed as AD might be prevented.

    Cerebrospinal fluid collection is fundamental to the investigation of central nervous system disorders although it carries potential risks. Herein we report the clinical signs and magnetic resonance (MR) imaging findings associated with needle injury to the brainstem during cerebellomedullary cistern puncture in four dogs. Three dogs were nonambulatory tetraparetic with cranial nerve deficits and one dog had unexplained left thoracic limb paresis. In MR images, there were conspicuous T2 hyperintensities in the myelencephalon in all dogs. In T2* gradient echo images, the lesions were hypointense in two dogs with multiple cranial nerve deficits, and hyperintense in another dog. One dog was euthanized due to sudden neurologic deterioration 12 days later, one died shortly after MR imaging, and a third was euthanized due to concurrent cervical spondylomyelopathy. The fourth dog recovered gradually. Diagnosis was confirmed histopathologically in one dog and was presumptive based on clinical signs and MR findings in three dogs. None of the dogs with cranial nerve deficits recovered, only the one dog with left thoracic limb paresis and concurrent syringomyelia. PMID:18833957

    Abstract Patients frequently suffer from lumbosacral plexus disorder. When conducting a neurological examination, it is essential to assess the extent of muscle paresis, sensory disorder distribution, pain occurrence, and blocked spine. An electromyography (EMG) can confirm axonal lesions and their severity and extent, root affliction (including dorsal branches), and disorders of motor and sensory fiber conduction. Imaging examination, particularly gadolinium magnetic resonance imaging (MRI) examination, ensues. Cerebrospinal fluid examination is of diagnostic importance with radiculopathy, neuroinfections, and for evidence of immunoglobulin synthesis. Differential diagnostics of lumbosacral plexopathy (LSP) include metabolic, oncological, inflammatory, ischemic, and autoimmune disorders. In the presented case study, a 64-year-old man developed an acute onset of painful LSP with a specific EMG finding, MRI showing evidence of plexus affliction but not in the proximal part of the roots. Painful plexopathy presented itself with severe muscle paresis in the femoral nerve and the obturator nerve innervation areas, and gradual remission occurred after 3 months. Autoimmune origin of painful LSP is presumed. We describe a rare case of patient with painful lumbar plexopathy, with EMG findings of axonal type, we suppose of autoimmune etiology. PMID:25929915

    Neuralgic amyotrophy (NA) is a distinct peripheral nervous system (PNS) disorder characterised by sudden attacks of neuropathic pain, usually in a unilateral upper extremity, and patchy paresis with amyotrophy. Under-recognition of NA patients may be frequent because symptoms of NA can be similar to those of common orthopedic disorders. The lesion sites of NA are commonly considered to be brachial plexus (BP) and/or individual branches of the BP. The cause of NA remains unknown. Some evidence support the concept of a complex pathogenesis in NA that includes underlying predisposition and susceptible PNS structures, and it can be triggered by infection, trauma, and strenuous exercise. Typical presentation of NA is characterized by patchy paresis of the periscapular and periglenohumeral muscles. In such cases, STIR-MRI often shows hyperintense signal abnormalities on the affected side of the proximal upper BP. NA is considered to be broad and encompasses a spectrum of atypical presentations, including involvement of lower part of BP, isolated nerves (anterior interosseous nerve or posterior interosseous nerve), or lumbosacral plexuses. Functional prognosis of NA is less favorable than previously assumed. Administration of corticosteroids and intravenous immunoglobulin was described as potential therapeutics for NA, although their efficacy remains unestablished. PMID:25672707

    Abstract Background: Mirror therapy (MT) was found to improve motor function after stroke. However, there is high variability between patients regarding motor recovery. Objectives: The following pilot study was designed to identify potential factors determining this variability between patients with severe upper limb paresis, receiving MT. Methods: Eleven sub-acute stroke patients with severe upper limb paresis participated, receiving in-patient rehabilitation. After a set of pre-assessments (including measurement of brain activity at the primary motor cortex and precuneus during the mirror illusion, using near-infrared spectroscopy as described previously), four weeks of MT were applied, followed by a set of post-assessments. Discriminant group analysis for MT responders and non-responders was performed. Results: Six out of eleven patients were defined as responders and five as non-responders on the basis of their functional motor improvement. The initial motor function and the activity shift in both precunei (mirror index) were found to discriminate significantly between responders and non-responders. Conclusions: In line with earlier results, initial motor function was confirmed as crucial determinant of motor recovery. Additionally, activity response to the mirror illusion in both precunei was found to be a candidate for determination of the efficacy of MT. PMID:26409402

    Mutations of the skeletal muscle voltage-gated sodium channel (NaV1.4) are an established cause of several clinically distinct forms of periodic paralysis and myotonia. Focal paresis has sometimes already been described. We report a case with atypical clinical manifestation comprising paramyotonia and cold-induced persistent and focal paralysis. A 27-year-old woman presented with paramyotonia congenita since her childhood. She experienced during her childhood one brief episode of generalised weakness. At the age of 27, she experienced a focal paresis lasting for several months. The known mutation p.Val1293Ile was found in the muscle sodium channel gene (SCN4A). Channel inactivation is involved in most Na+ channelopathies. Fast inactivation is known to be responsible for the myotonia phenotype. We hypothesise that the V1293I mutation may also alter the slow inactivation in specific conditions, for example, prolonged cold exposure or prolonged and intensive exercise. This observation broadens the spectrum of clinical manifestations of this sodium channel mutation. PMID:24939454

    This study aimed to evaluate the efficacy and safety of reirradiation with intensity-modulated radiation therapy (IMRT) for spinal metastases. We retrospectively analyzed 23 patients with spinal metastases who underwent IMRT reirradiation between December 2006 and July 2013. We evaluated the spinal radiation doses during the first and second radiation therapy courses, the interval between the courses, and the clinical outcomes after reirradiation, including skeletal-related events, local control rates (LCRs), overall survival (OS), and toxicities. The median time from the first irradiation to reirradiation was 13 months (range, 2–75 months). The median reirradiation dose delivered to 90% of the planning target volume was 24.5 Gy in 5 fractions (range, 14.7–50 Gy in 3–25 fractions). Nineteen patients experienced pain at reirradiation, and 15 of these attained pain relief. Two of the three patients with paresis in the upper or lower extremities upon initiation of reirradiation demonstrated improvement. Local progression was identified in four patients. The median time to local progression was 37 months. The 1- and 2-year LCRs after reirradiation were 88% and 75%, respectively. The 1- and 2-year OS rates after reirradiation were 45% and 20%, respectively, with a median OS of 12 months. No late toxicities occurred. In conclusion, spinal metastasis reirradiation using IMRT appears safe; pain relief and paresis improvement and/or prevention can be expected, along with a reduced risk of radiation-induced toxicity, especially in the spinal cord.

    Hysteria has served as an important driving force in the development of both neurology and psychiatry. Jean Martin Charcot's devotion to mesmerism for treating hysterical patients evoked the invention of psychoanalysis by Sigmund Freud. Meanwhile, Joseph Babinski took over the challenge to discriminate between organic and hysterical patients from Charcot and found Babinski's sign, the greatest milestone in modern neurological symptomatology. Nowadays, the usage of the term hysteria is avoided. However, new terms and new classifications are complicated and inconsistent between the two representative taxonomies, the DSM-IV and ICD-10. In the ICD-10, even the alternative term conversion disorder, which was becoming familiar to neurologists, has also disappeared as a group name. The diagnosis of hysteria remains important in clinical neurology. Extensive exclusive diagnoses and over investigation, including various imaging studies, should be avoided because they may prolong the disease course and fix their symptoms. Psychological reasons that seem to explain the conversion are not considered reliable. Positive neurological signs suggesting nonorganic etiologies are the most reliable measures for diagnosing hysteria, as Babinski first argued. Hysterical paresis has several characteristics, such as giving-way weakness or peculiar distributions of weakness. Signs to uncover nonorganic paresis utilizing synergy include Hoover's test and the Sonoo abductor test. PMID:24998831

    The American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) has published a supplement to this issue featuring the new Clinical Practice Guideline: Bell's Palsy. To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 11 recommendations developed encourage accurate and efficient diagnosis and treatment and, when applicable, facilitate patient follow-up to address the management of long-term sequelae or evaluation of new or worsening symptoms not indicative of Bell's palsy. There are myriad treatment options for Bell's palsy; some controversy exists regarding the effectiveness of several of these options, and there are consequent variations in care. In addition, there are numerous diagnostic tests available that are used in the evaluation of patients with Bell's palsy. Many of these tests are of questionable benefit in Bell's palsy. Furthermore, while patients with Bell's palsy enter the health care system with facial paresis/paralysis as a primary complaint, not all patients with facial paresis/paralysis have Bell's palsy. It is a concern that patients with alternative underlying etiologies may be misdiagnosed or have an unnecessary delay in diagnosis. All of these quality concerns provide an important opportunity for improvement in the diagnosis and management of patients with Bell's palsy. PMID:24190889

    The anterior cervical spine surgery is a common procedure to stabilize vertebrae damaged by various diseases. The plates and screws are usually used in the spine fixation. This kind of instrumentation may detach from the bones which is a rare but well-known complication. A 77-year-old male presented to the otorhinolaryngology department with throat pain, choking, and dysphagia. At first the angioedema was diagnosed and he was treated conservatively. The endoscopy revealed laryngeal edema, being more defined on the right side with right vocal fold paresis. CT scans showed the stabilizing plate with two screws attached tightly and the back-out of the third screw toward soft tissue of the neck. In the meantime, his condition deteriorated and he needed tracheotomy. In few days the surgical removal of the dislocated screw was performed successfully. Although two-month follow-up reported no obstruction of the larynx, the vocal folds paresis with gradual functional improvement was observed. Long-term complication of anterior spine surgery sometimes may suggest laryngeal angioedema at first. If the conservative treatment is ineffective and there is a history of anterior spine surgery, the clinicians should consider the displacement of the plate or screws in differential diagnosis.

    Amyothropic neuralgy is a rare disease witch unknown etiopathogenesis. The main popular theory says that inflammatory and immunomodulatory process is connected with that disease. Diagnosis is made after exclusion of other causes of plexus lumbosacralis damage. The main symptom is neuropathic pain after which there is observed muscle weakness and atrophy. ENG/EMG study and MRI are made to confirm the diagnosis. In this study we described a case of 52 years old female with lower limbs paresis, who was diagnosed few years after first symptoms. Limb paresis was preluded by lumbar pain. MRI study revealed central spinal disc herniations on L1-2, L2-3, L3-4 levels with dura matter compression, L4-5 spinal disc right lateral herniation and synovial cyst. MRI of both lumbar plexuses was also normal. EMG study revealed features of bilateral, chronic damage of lower legs nerves on lumbar plexus level. Patient was treated with physiotherapy and gabapentin with dose of 2x600mg per day. PMID:25771520

  12. Acute paretic syndrome in juvenile White Leghorn chickens resembles late stages of acute inflammatory demyelinating polyneuropathies in humans

    2010-01-01

    Background Sudden limb paresis is a common problem in White Leghorn flocks, affecting about 1% of the chicken population before achievement of sexual maturity. Previously, a similar clinical syndrome has been reported as being caused by inflammatory demyelination of peripheral nerve fibres. Here, we investigated in detail the immunopathology of this paretic syndrome and its possible resemblance to human neuropathies. Methods Neurologically affected chickens and control animals from one single flock underwent clinical and neuropathological examination. Peripheral nervous system (PNS) alterations were characterised using standard morphological techniques, including nerve fibre teasing and transmission electron microscopy. Infiltrating cells were phenotyped immunohistologically and quantified by flow cytometry. The cytokine expression pattern was assessed by quantitative real-time PCR (qRT-PCR). These investigations were accomplished by MHC genotyping and a PCR screen for Marek's disease virus (MDV). Results Spontaneous paresis of White Leghorns is caused by cell-mediated, inflammatory demyelination affecting multiple cranial and spinal nerves and nerve roots with a proximodistal tapering. Clinical manifestation coincides with the employment of humoral immune mechanisms, enrolling plasma cell recruitment, deposition of myelin-bound IgG and antibody-dependent macrophageal myelin-stripping. Disease development was significantly linked to a 539 bp microsatellite in MHC locus LEI0258. An aetiological role for MDV was excluded. Conclusions The paretic phase of avian inflammatory demyelinating polyradiculoneuritis immunobiologically resembles the late-acute disease stages of human acute inflammatory demyelinating polyneuropathy, and is characterised by a Th1-to-Th2 shift.

We investigated how human activity interacted with maternal status and individual variation in behavior to affect reliability of spatially-explicit models intended to guide conservation of critical ungulate calving resources. We studied Rocky Mountain elk (Cervus elaphus) that occupy a region where 2900 natural gas wells have been drilled. Methodology/Principal Findings We present novel applications of generalized additive modeling to predict maternal status based on movement, and of random-effects resource selection models to provide population and individual-based inference on the effects of maternal status and human activity. We used a 2×2 factorial design (treatment vs. control) that included elk that were either parturient or non-parturient and in areas either with or without industrial development. Generalized additive models predicted maternal status (parturiency) correctly 93% of the time based on movement. Human activity played a larger role than maternal status in shaping resource use; elk showed strong spatiotemporal patterns of selection or avoidance and marked individual variation in developed areas, but no such pattern in undeveloped areas. This difference had direct consequences for landscape-level conservation planning. When relative probability of use was calculated across the study area, there was disparity throughout 72–88% of the landscape in terms of where conservation intervention should be prioritized depending on whether models were based on behavior in developed areas or undeveloped areas. Model validation showed that models based on behavior in developed areas had poor predictive accuracy, whereas the model based on behavior in undeveloped areas had high predictive accuracy. Conclusions/Significance By directly testing for differences between developed and undeveloped areas, and by modeling resource

    Background Spasticity after stroke has been internationally recognized as an important health problem causing impairment of mobility, deformity, and pain. The aim of this study was to assess the frequency of first-ever and recurrent stroke and of subsequent spastic and flaccid paresis. Factors influencing the development of spasticity were analyzed. A further major aim was to provide a “real-life” assessment of the treatment of spasticity in Germany and to discuss this in view of the treatment recommended by German and international clinical guidelines. Methods The database used in this study comprised a cohort of 242,090 insurants from a large statutory health insurance fund in the federal state of Hesse, Germany. A first hospital discharge diagnosis in 2009 with any of the International Classification of Diseases, Tenth Revision (ICD-10) codes I60–I64 was used to identify patients with acute stroke (hemorrhage and ischemic). These patients were followed up six months after stroke to monitor whether they developed spastic or flaccid paresis (hospital or ambulatory care diagnoses ICD-10 code G81–G83 [excluding G82.6/G83.4/G83.8]). For patients with spastic paresis after stroke the spasticity treatment was analyzed for a six-month period (physiotherapy, oral muscle relaxants, intrathecal baclofen, and botulinum toxin). Results Standardized to the population of Germany, 3.7 per 1000 persons suffered a stroke in 2009 (raw 5.2/1000). Of all surviving patients, 10.2% developed spasticity within 6 months. Cox regression revealed no significant influence of patient age, gender, morbidity (diabetes, hypertensive diseases, ischemic heart diseases) or type of stroke on development of spasticity. 97% of surviving patients with spasticity received physiotherapy (inpatient care 89%, ambulatory care 48%). Oral muscle relaxants were prescribed to 13% of the patients. No patient received intrathecal baclofen or botulinum toxin. Conclusion Claims data enabled analysis of

    Literature on the use of plasma cortisol to quantify psychophysiological stress in humans is extensive. However, in parturition at term gestation the use of cortisol as a biomarker of stress is particularly complex. Plasma cortisol levels increase as labor progresses. This increase seems to be important for maintenance of maternal/fetal wellbeing and facilitation of normal labor progress. Unique physiological and methodological issues involved in the use of cortisol as a biomarker of stress in labor present challenges for researchers. This review examines these issues, suggests mixed methods and within-subject repeated measures designs, and offers recommendations for assay procedures for parturient sampling. Documentation of clinical interventions and delivery outcomes may elucidate relationships among psychophysiological stressors, cortisol and normal labor progress. With attention to these methodological issues, analysis of plasma cortisol may lead to clinical interventions that support normal labor physiology. PMID:23338011

    Anesthesia providers in low-income countries may infrequently provide regional anesthesia techniques for obstetrics due to insufficient training and supplies, limited manpower, and a lack of perceived need. In 2007, Kybele, Inc. began a 5-year collaboration in Ghana to improve obstetric anesthesia services. A program was designed to teach spinal anesthesia for cesarean delivery and spinal labor analgesia at Ridge Regional Hospital, Accra, the second largest obstetric unit in Ghana. The use of spinal anesthesia for cesarean delivery increased significantly from 6% in 2006 to 89% in 2009. By 2012, >90% of cesarean deliveries were conducted with spinal anesthesia, despite a doubling of the number performed. A trial of spinal labor analgesia was assessed in a small cohort of parturients with minimal complications; however, protocol deviations were observed. Although subsequent efforts to provide spinal analgesia in the labor ward were hampered by anesthesia provider shortages, spinal anesthesia for cesarean delivery proved to be practical and sustainable.

    Obstetric anesthesia is one of the high risk subspecialties of anesthesia practice. Anesthesia related complications are the sixth leading cause of maternal mortality. Difficult or failed intubation following induction of general anesthesia for CS remains the major contributory factor to anesthesia-related maternal complications. The airway management of obstetric patients is a challenging issue for several reasons. Anatomic and physiologic changes related to pregnancy may increase the difficult and failed intubation rates compared to the general surgical population. Proper evaluation of the airway anatomy and airway structures is vital to prevent airway management related catastrophes. In addition to basic airway and intubation equipment, each anesthesia department must have difficult intubation equipment cart including fiber optic laryngoscope, video laryngoscopes, and different types of laryngeal masks. It is essential that all anesthesiologists have a preconceived and well thought-out algorithm and emergency airway equipment to deal with airway emergencies during difficult or failed intubation of a parturient.

    This is the first report of an acute and fatal outbreak of bovine diarrhea virus (BVDV)-2 infection in Israel. The clinical presentation varied with the age of the affected animals with a bovine-respiratory-complex-like syndrome in young stock, and diarrhea and dysentery only in the lactating stock. Enteritis first appeared in one shed of post-parturient cows; it spread for 6 weeks, until at least 30% of the lactating stock contracted enteritis or dysentery. At the same time, dairy calves aged 10-90 days exhibited severe respiratory disease. Of 79 animals that died, 13/350 (3.7%) were adult lactating cows, and 66/1100 (6%) were young feedlot calves. Phylogenetic analysis of the isolated virus revealed a 95% identity with the corresponding genome parts of various BVDV type 2 sequences. The route of introduction of BVDV-2 into Israel could not be elucidated. PMID:20656535

    Postpartum hemorrhage (PPH) remains a leading cause of maternal mortality and morbidity worldwide. This retrospective observational study describes patient characteristics and hemostatic therapies administered to 352 parturients experiencing PPH and analyzes risk factors for developing severe PPH. During the study period, bleeding was controlled in all cases and 99.4% survived. The majority (98%) of patients received packed red blood cells. The most frequent hemostatic therapies administered were fibrinogen concentrate (56%), fresh frozen plasma (49%), and platelets (30%). A total of 124 (35%) women experienced severe PPH. Significant independent predictors for evolution to severe PPH were age, obstetric comorbidity, and plasma fibrinogen concentration. The latter was based on records from 267 (76%) patients. Plasma fibrinogen concentration before labor was the only modifiable prepartum risk factor independently associated with severe PPH, indicating that fibrinogen monitoring is warranted in these patients.

    Perioperative management of patients receiving opioid addiction therapy presents a unique challenge for the anesthesiologist. The goal of pain management in this patient population is to effectively manage postoperative pain, to improve patient satisfaction and outcomes, and to reduce the cost of health care. Multimodal analgesics, including nonsteroid anti-inflammatory drugs, intravenous acetaminophen, gabapentanoid agents, and low-dose ketamine infusions, have been used to improve postoperative pain and to reduce postoperative opioid use. Patients on long-term opioid management therapy with methadone and buprenorphine require special considerations. Recommendations and options for treating postoperative pain in patients on methadone and buprenorphine are outlined below. Other postoperative pain management options include patient-controlled analgesia, intravenous, and transdermal, in addition to neuraxial and regional anesthesia techniques. Special patient populations include the parturient on long-term opioid therapy. Recommendations for use of opioids in these patients during labor and delivery and in the postpartum period are discussed. PMID:26879874

    Acute aortic dissection occurring during pregnancy represents a lethal risk to both the mother and fetus. Management of parturient with acute aortic dissection is complex. We report our experience of two pregnancies with type A acute aortic dissection. One patient is a 31-year-old pregnant woman (33rd gestational week) with a bicuspid aortic valve and the other is a 32-year-old pregnant woman (30th gestational week) with the Marfan syndrome. In both cases, a combined emergency operation consisting of Cesarean section, total hysterectomy prior to corrective surgery for aortic dissection was successfully performed within a relatively short period of time after the onset. Both patients' postoperative recovery was uneventful, and we achieved a favorable maternal and fetal outcome. PMID:25085319

    Pregnancy-related mortality, estimated to occur in approximately 1: 50,000 deliveries, is rare in developed countries. The 2010 American Heart Association (AHA) Guidelines for Resuscitation emphasize the importance of high-quality chest compression as a key determinant of successful cardiopulmonary resuscitation. During pregnancy, the uterus can compress the inferior vena cava, impeding venous return and thereby reducing stroke volume and cardiac output. To maximize the effectiveness of chest compressions in pregnancy, the AHA guidelines recommend the 27-30 degrees left-lateral tilt (LLT) position. When CPR is performed on parturients in the LLT position, chest compressions will probably be more effective if performed with the operator standing on the left side of the patient. The videolaryngoscope Pentax-AWS Airwayscope (AWS) was found to be an effective tool for airway management during chest compressions in 27 LLT simulations, suggesting that the AWS may be a useful device for airway management during maternal resuscitation.

    Opioids have been administered intrathecally with subarachnoid block for postoperative pain relief in parturients undergoing elective cesarean deliveries. This case report presents the uncommon occurrence of intrathecal opioid-induced hypothermia in the latent phase of recovery following elective cesarean delivery. There are few case reports on the occurrence of latent-phase postanesthesia care hypothermia in patients receiving subarachnoid block with morphine sulfate injection (Duramorph). Hypothermia can occur postoperatively for many reasons and can be life-threatening. In this case, hypothermia developed and progressed throughout the postoperative period. The causes of hypothermia were evaluated and treated without success initially. Thyroid dysfunction and alternative differential diagnoses were ruled out. Further assessment determined that the morphine injection might have been a contributing factor. Naloxone at 40-μg increments was administered intravenously and corrected the hypothermia. Awareness of hypothermia postoperatively with associated morphine administration through subarachnoid block must be ruled out in cases of progressing hypothermia. PMID:26939385

    Amniotic fluid embolism (AFE) is an unpredictable and as-of-yet unpreventable complication of maternity. With its low incidence it is unlikely that any given practitioner will be confronted with a case of AFE. However, this rare occurrence carries a high probability of serious sequelae including cardiac arrest, ARDS, coagulopathy with massive hemorrhage, encephalopathy, seizures, and both maternal and infant mortality. In this review the current state of medical knowledge about AFE is outlined including its incidence, risk factors, diagnosis, pathophysiology, and clinical manifestations. Special attention is paid to the modern aggressive supportive care that resulted in an overall reduction in the still alarmingly high mortality rate of this devastating entity. The key factors for successful management and resolution of this disease process continue to be sharp vigilance, a high level of clinical suspicion, and rapid all-out resuscitative efforts on the part of all clinicians involved in the medical care of the parturient.

    2012-01-01

    Amniotic fluid embolism (AFE) is one of the leading causes of maternal mortality and morbidity in developed countries. Current thinking about pathophysiology has shifted away from embolism toward a maternal immune response to the fetus. Two immunologic mechanisms have been studied to date. Anaphylaxis appears to be doubtful while the available evidence supports a role for complement activation. With the mechanism remaining to be elucidated, AFE remains a clinical diagnosis. It is diagnosed based on one or more of four key signs/symptoms: cardiovascular collapse, respiratory distress, coagulopathy, and/or coma/seizures. The only laboratory test that reliably supports the diagnosis is the finding of fetal material in the maternal pulmonary circulation at autopsy. Perhaps the most compelling mystery surrounding AFE is not why one in 20,000 parturients are afflicted, but rather how the vast majority of women can tolerate the foreign antigenic presence of their fetus both within their uterus and circulation?

    Amniotic fluid embolism is a rare and diagnostically challenging obstetric disease of high mortality rate. We present a case of a 33-year old parturient after vaginal birth, who presented with severe hemorrhagic shock with low platelet count and coagulopathy resistant to treatment with plasma, platelets and coagulation factors and despite of surgical management of bleeding. Laboratory findings revealed consumptive coagulopathy. Other symptoms included dyspnea and atelectatic changes on chest x-ray, together with augmentation of the heart with no proof of ventricular insufficiency in echocardiographic examination. The suspected reason of these alterations was amniotic fluid embolism. The patient survived and came back to her usual activity after 22 days of treatment. PMID:27306294

    Intraoperative cell salvage is a strategy to decrease the need for allogeneic blood transfusion. Traditionally, cell salvage has been avoided in the obstetric population because of the perceived risk of amniotic fluid embolism or induction of maternal alloimmunization. With advances in cell salvage technology, the risks of cell salvage in the obstetric population parallel those in the general population. Levels of fetal squamous cells in salvaged blood are comparable to those in maternal venous blood at the time of placental separation. No definite cases of amniotic fluid embolism have been reported and appear unlikely with modern equipment. Cell salvage is cost-effective in patients with predictably high rates of transfusion, such as parturients with abnormal placentation. PMID:26197375

    Our goal was to determine the prevalence of Trichomonas vaginalis and its associated risk factors in parturient women aged 15-24 years attending Brazilian public maternity units. Participants answered a demographic, behavioral, and clinical data questionnaire. A sample of urine was screened for T. vaginalis. A total 299 women participated in this study. The prevalence rate of T. vaginalis was 7.7% (95% CI: 4.7-10.7%). The factors associated with T. vaginalis were use of illicit drugs [OR=4.70 (95% CI: 1.63-13.56, p=0.004)] and not attending antenatal care [OR=5.15 (95% CI: 1.15-23.25, p=0.032)]. These data demonstrate that it is important to discuss how to include routine screening for T. vaginalis during antenatal care in Brazil. PMID:25181400

    We report two cases of aortic coarctation in pregnancy. The first was a 20-year-old nulliparous woman who underwent an aortic coarctation repair when she was 23 weeks old and subsequently developed an aneurysm at the site of initial repair. The second was a 20-year-old nulliparous woman with a severe uncorrected congenital aortic coarctation and upper body hypertension, who became pregnant whilst awaiting transcatheter dilatation of the coarctation. Antenatal care involved a multidisciplinary approach with obstetric, anaesthetic and cardiology input. Both parturients were delivered by elective caesarean section. A cautious, incremental regional anaesthetic technique was used, with no associated maternal or neonatal morbidity. Perioperative management focused on minimising haemodynamic disturbances. The management is discussed, together with the potential maternal and fetal complications of aortic coarctation in pregnancy. PMID:15477059

    Information on fetal weight is of importance to obstetricians in the management of pregnancy and delivery. The objective of this study is to compare the accuracy of clinical and sonographic methods of predicting fetal weights at term. This prospective comparative study of 200 parturients was conducted at the University of Calabar Teaching Hospital, Calabar. The study participants were mothers with singleton term pregnancy admitted for delivery. The mean absolute percentage errors of both clinical and ultrasound methods were 11.16% ± 9.48 and 9.036% ± 7.61, respectively, and the difference was not statistically significant (P = 0.205). The accuracy within 10% of actual birth weights was 69.5% and 72% for both clinical estimation of fetal weight and ultrasound, respectively, and the difference was not statistically significant (P = 0.755). The accuracy of fetal weight estimation using Dare's formula is comparable to ultrasound estimates for predicting birth weight at term.

    Maternal antibodies against cytomegalovirus (CMV) infection offer, to some extent, protection against congenital CMV infection. This study describes the seroprevalence of CMV-specific IgG in 220 parturient women during pregnancy, at delivery, at 3 months after delivery and in their cord blood (Flanders, Belgium, 2006-2008). ELISA was used to measure IgG. Of this population, 30% had positive IgG titres. Active transplacental transport was confirmed with a ratio 1.15/1. Elevated maternal IgG titre and increased parity, but not age, were significantly associated with higher seroprevalence of CMV-specific IgG in the cord blood. These data indicate a high susceptibility to CMV among fertile women. Prenatal prevention and other strategies to prevent intra-uterine infection are of critical importance in a highly susceptible population. PMID:24753893

    Background: Dengue infection during peripartum period, although rare in endemic regions, has challenged clinicians regarding its management, especially if a parturient woman experiences postpartum hemorrhage due to a classical risk factor of maternal bleeding. Case: A full-term pregnant Vietnamese woman was diagnosed with polyhydramnios and Dengue with warning signs (DWS). She was administered platelet transfusion prior to delivery and then gave birth to a healthy newborn. After active management of the third stage of labor, the patient suffered a postpartum hemorrhage which was caused by uterine atony and accompanied with thrombocytopenia. Therefore, we decided to administer uterotonic drugs and additionally transfuse platelets. Conclusion: We describe a case of postpartum hemorrhage caused by uterine atony and coinciding with Dengue infection during delivery period, which is a rare clinical entity. With timely detection and management, the patient was finally discharged without complications. PMID:26925224

    During pregnancy, an obstetrician can encounter various complications and sometimes require surgery or operative intervention for delivery. However, the role of anaesthesiologists during such clinical scenario is grossly under-estimated. Without any close coordination and team work among obstetricians, neonatologists and an anaesthesiologist, morbidity and mortality can increase during these surgical interventions. The clinical scenario can become more challenging if the parturient suffers from any comorbid diseases. The present article reviews some of the common challenging scenarios during pregnancy that an anaesthesiologist frequently encounters during routine practice. Anaesthetic management has been discussed briefly and separately for each trimester and post-partum period. The article also aims at gaining in-depth knowledge of these obstetrical and surgical emergencies so as to ensure close-knit team work among obstetricians, anaesthesiologists, intensivists and a neonatologist.

    Drug abuse is a significant social problem that can lead to serious obstetric complications, some of which may be confused with pregnancy-related disease states. Substance abuse poses a number of challenges with respect to the management of pain and the conduct of anaesthesia in the peripartum period. This review was based on information from a literature search of epidemiological, research and review papers on substance abuse during pregnancy, obtained for the purpose of preparing a background paper for the Ministerial Council on Drug Strategy, Commonwealth Government of Australia. Given that almost 80% of substance-abusing parturients require anaesthetic services in the perinatal period, early antenatal referral for anaesthetic review is recommended. To optimise the care of these vulnerable patients, obstetricians, general practitioners and midwives should attempt to identify substance-abusing parturients and refer them to an anaesthetist. A careful anaesthetic evaluation with non-judgemental questioning is essential, with management tailored to individual patient needs and the urgency of obstetric intervention for vaginal delivery or caesarean section. Opioid-dependent women, in particular, benefit from antenatal pain management planning. Patients recovering from drug addiction should also have a well-documented analgesic strategy. A multidisciplinary approach will involve obstetricians, anaesthetists and staff of the Drug and Alcohol Service. In acute admissions of women by whom antenatal care was not accessed, a high index of suspicion for illicit drug use should arise. Because illicit substance use is so prevalent, if untoward reactions occur during an otherwise uneventful anaesthetic, the possibility of drug abuse should be considered. PMID:18084978

    Background: Multiple trials have been tried to prevent hypotension during spinal anesthesia. However, the drug choice and mode of administration is still a matter of debate. Objectives: To compare the outcome of spinal injection of hyperbaric bupivacaine and fentanyl separately to standard injection of mixed fentanyl with hyperbaric bupivacaine. Settings and Design: A randomized, controlled clinical trial. Patients and Methods: One hundred twenty-four parturient scheduled for elective cesarean section were randomly allocated into two groups, each 62 parturient: Group M received spinal anesthesia using 10 mg bupivacaine 0.5% premixed with 25 μg fentanyl in the same syringe and Group S received 25 μg fentanyl in one syringe and 10 mg bupivacaine 0.5% without barbotage in a second syringe. Results: Patients with intraoperative pain that was controllable without the need for a shift to general anesthesia was significantly lower in Group S (3.2%) than in Group M (16.1%). The frequency of hypotension was significantly lower in Group S compared to Group M (P < 0.05). Time till the onset of sensory block was nonsignificantly shorter with nonsignificantly higher mean level of maximal sensory block in Group S compared to Group M (P > 0.05). There was no significant difference in the time till occurrence of hypotension, duration of hypotension, mean dose of ephedrine used for the treatment of hypotension and frequency of patients developed itching between the groups (P > 0.05). Conclusion: Separate intrathecal injection of fentanyl and hyperbaric bupivacaine provided a significant improvement in the quality of sensory block and significant reduction of the frequency of hypotension compared to injection of mixed medications.

    Background There is a legal obligation to explain the procedure and use of epidural analgesia in labor primarily due to the possibility of potential risks and associated complications. The present study details on the survey carried out to ascertain the current status of obtaining informed consent (IC) for explaining the epidural analgesia in labor. Methods The present study is based on a survey through a telephone questionnaire that covered all the hospitals in Korea where the anesthesiologists' belonged to and are registered with Korean Society of Anesthesiologists. The questionnaire included questions pertaining to administration of epidural analgesia to a parturient, information on different steps of obtaining an IC, whether patient status was evaluated, when the consent was obtained, and the reasons behind, if the consent had not being given. Results A total of 1,434 respondents took part in the survey, with a response rate of 97% (1,434/1,467). One hundred seventy-four hospitals had conducted epidural analgesia on the parturient. The overall rate of obtaining IC for epidural analgesia during labor was 85%, of which only 13% was conducted by anesthesiologists. The rate of evaluating preoperative patient status was 74%, of which 45% was conducted by anesthesiologists. Almost all of the consent was obtained prior to the procedure. Conclusions The rate of obtaining IC for epidural analgesia in labor is relatively high (85%) in Korea. However, it is necessary to discuss the content of the consent and the procedure followed for obtaining IC during the rapid progress of labor. PMID:20651996

    Although a marginal placental transfer of maternal immunoglobulin (Ig) has been demonstrated in buffalo, the colostrum still provides the main source of immune components and nutrients to neonate buffalo calves. The neonatal Fc receptor (FcRn) transports maternal Ig across the gut wall and is involved in the transport of IgG in the mammary gland. In this study we used RT-PCR to examine the gene expression of FcRn in the mammary gland during several physiological states of the Egyptian water buffalo. The buffalo FcRn showed a high sequence homology to that of other mammalian species and especially the cow. Immunohistochemistry demonstrated positive immunolabelling of FcRn in the epithelial cells of the acini and ducts of the examined mammary gland tissue. Remarkable differences in both the cellular localization and in the intensity of FcRn immunopositivity were observed depending on the functional state of the mammary gland tissues. In late pregnancy, the FcRn immunolabelling was homogeneously distributed in the cytoplasm of the epithelial cells. In recently parturient animals, positive FcRn immunolabelling was mainly located at the luminal surface and apical cytoplasm of the mammary gland epithelium, while in dry and lactating animals, the FcRn immunolabelling was in the apical cytoplasm of the cells. The strongest FcRn immunolabelling was observed in late pregnancy and in recently parturient animals. In conclusion, the present data support the notion that FcRn might be involved in the transfer of maternal immunoglobulins and in the local defense mechanism of the mammary gland. PMID:19481783

    Alcohol consumption in young women is a widespread habit that may continue during pregnancy and induce alterations in the fetus. We aimed to characterize prevalence of alcohol consumption in parturient women and to assess fetal ethanol exposure in their newborns by analyzing two direct metabolites of ethanol in meconium. This is a cross-sectional study performed in September 2011 and March 2012 in a series of women admitted to an obstetric unit following childbirth. During admission, socio-demographic and substance use (alcohol, tobacco, cannabis, cocaine, and opiates) during pregnancy were assessed using a structured questionnaire and clinical charts. We also recorded the characteristics of pregnancy, childbirth, and neonates. The meconium analysis was performed by liquid chromatography—tandem mass spectrometry (LC-MS/MS) to detect the presence of ethyl glucuronide (EtG) and ethyl sulfate (EtS). Fifty-one parturient and 52 neonates were included and 48 meconium samples were suitable for EtG and EtS detection. The median age of women was 30 years (interquartile range (IQR): 26–34 years); EtG was present in all meconium samples and median concentration of EtG was 67.9 ng/g (IQR: 36.0–110.6 ng/g). With respect to EtS, it was undetectable (<0.01 ng/g) in the majority of samples (79.1%). Only three (6%) women reported alcohol consumption during pregnancy in face-to-face interviews. However, prevalence of fetal exposure to alcohol through the detection of EtG and EtS was 4.2% and 16.7%, respectively. Prevention of alcohol consumption during pregnancy and the detection of substance use with markers of fetal exposure are essential components of maternal and child health. PMID:27011168

    Background: Use of analgesics, especially opioids, before delivery during cesarean section for preventing hemodynamic changes after endotracheal intubation and postoperative analgesia is limited due to their adverse effects on the neonate. Objectives: The aim of this study was to investigate the effect of intravenous acetaminophen (paracetamol) in blunting hemodynamic responses to endotracheal intubation and postoperative pain in parturient undergoing cesarean section by general anesthesia. Patients and Methods: Eighty parturients undergoing cesarean section by general anesthesia were randomly divided to receive either 15 mg/kg intravenous paracetamol (n = 40) or normal saline (n = 40) fifteen minutes before endotracheal intubation. Mean arterial blood pressure (MAP) and pulse rates were compared at baseline and after intubation at one minute interval for five minutes between the two groups. The patients were also compared for postoperative pain intensity and analgesic requirement. Results: Patients in the saline group experienced more pain in the recovery room (VAS 7.0 ± 1.24 vs. 6.15 ± 2.27; P value = 0.041) and required more fentanyl intraoperatively (150 µg vs. 87.7 ± 75; P value < 0.01) and meperidine postoperatively (12.88 ± 20.84 mg vs. 1.35 ± 5.73; P value = 0.002) than the paracetamol group. Mean arterial pressure (MAP) changes were similar after intubation in the both groups (P value = 0.71), however, pulse rates showed greater changes following intubation in the saline group (P value = 0.01). Conclusions: Intravenous acetaminophen administered before caesarean section reduced tachycardia after intubation, narcotic drugs administration during and after the operation and reduced pain in PACU.

    Background and Aims: Low concentration local anaesthetic improves uteroplacental blood flow in antenatal period and during labour in preeclampsia. We compared neonatal outcome after epidural ropivacaine plus fentanyl with intramuscular tramadol analgesia during labour in high-risk parturients with intrauterine growth restriction of mixed aetiology. Methods: Forty-eight parturients with sonographic evidence of foetal weight <1.5 kg were enrolled in this non-randomized, double-blinded prospective study. The epidural (E) group received 0.15% ropivacaine 10 ml with 30 μg fentanyl incremental bolus followed by 7–15 ml 0.1% ropivacaine with 2 μg/ml fentanyl in continuous infusion titrated until visual analogue scale was three. Tramadol (T) group received intramuscular tramadol 1 mg/kg as bolus as well as maintenance 4–6 hourly. Neonatal outcomes were measured with cord blood base deficit, pH, ionised calcium, sugar and Apgar score after delivery. Maternal satisfaction was also assessed by four point subjective score. Results: Baseline maternal demographics and neonatal birth weight were comparable. Neonatal cord blood pH, base deficit, sugar, and ionised calcium levels were significantly improved in the epidural group in comparison to the tramadol group. Maternal satisfaction (P = 0.0001) regarding labour analgesia in epidural group was expressed as excellent by 48%, good by 52% whereas it was fair in 75% and poor in 25% in the tramadol group. Better haemodynamic and pain scores were reported in the epidural group. Conclusion: Epidural labour analgesia with low concentration local anaesthetic is associated with less neonatal cord blood acidaemia, better sugar and ionised calcium levels. The analgesic efficacy and maternal satisfaction are also better with epidural labour analgesia. PMID:27013750

    The objective of this study was to test whether supplementing dry cow rations with phosphorus (P) and magnesium (Mg) would interfere with the beneficial effect of zeolite supplementation on the periparturient blood calcium (Ca) concentration in dairy cattle. Three groups (A-C) of 10 Danish Jersey cows were each given the following daily supplements from 2 weeks before the expected date of calving until actual calving: group A: zeolite, monoammonium phosphate, standard dry cow mineral and vitamin mix, containing 61g magnesium phosphate; group B: zeolite, standard mineral and vitamin mix without the magnesium phosphate and group C: standard mineral and vitamin mix, monoammonium phosphate. All cows in group B had an apparently less variable serum calcium concentration around calving with no cases of milk fever and no subclinical hypocalcaemia or hypomagnesaemia recorded. In contrast, a parturient drop in blood Ca was seen in group A as well as group C. In group A, one cow was hypocalcaemic at calving, and developed milk fever. In group C, 12 blood samples, representing six cows, were hypocalcaemic, and three of these cows were treated for milk fever. All groups remained normomagnesaemic and there were no significant differences in blood Mg across groups. In conclusion, the combined P and Mg supplementation in addition to zeolite supplementation did not increase the serum Mg level (forage Mg 16.9g/day; 0.21% of DM). Combined P and Mg supplementation reduced the zeolite-induced hypophosphataemia but also reduced the stabilising effect of zeolite on parturient serum Ca. PMID:17600739

    Although a molecular diagnostic assay using clinically accessible tissue, such as blood, would facilitate evaluation of disease conditions in humans and animals, little information exists on microarray-based gene expression profiling of circulating leukocytes from clinically hypocalcemic cows. Therefore, peripheral blood mononuclear cells from dairy cows with experimentally induced hypocalcemia or spontaneous milk fever were subjected to oligo-microarray analysis to identify specific biomarker genes. In experimental hypocalcemia induced by a 4-h infusion of 10% disodium EDTA (n=4), 32 genes were significantly up- or downregulated compared with control treatment (4-h infusion of 11% calcium EDTA; n=4). In cows with milk fever (n=8), 98 genes were expressed differentially (either up- or downregulated) compared with healthy parturient cows (n=5). From these data, the following 5 genes were selected as being strongly related to both experimental hypocalcemia and milk fever: protein kinase (cAMP-dependent, catalytic) inhibitor β (PKIB); DNA-damage-inducible transcript 4 (DDIT4); period homolog 1 (PER1); NUAK family, SNF1-like kinase, 1 (NUAK1); and expressed sequence tag (BI537947). Another gene (neuroendocrine secretory protein 55, NESP55) was also determined to be specific for milk fever, independently of hypocalcemia. The mRNA expression of these 6 genes in milk fever cases was verified by quantitative real-time reverse-transcription PCR and was significantly different compared with their expression in healthy parturient cows. In the present study, the selected genes appeared to be candidate biomarkers of milk fever because the continuous interactions between blood cells and the entire body suggest that subtle intracellular changes occur in association with disease. However, before any genomic biomarkers are incorporated into clinical evaluation of the disease, the effect of hypocalcemia on the mRNA expression of these genes in the tissues that regulate calcium

    Background The aim of this study was to assess the diagnostic values of three breast tumor markers (i.e., CEA, CA153 and CA125) in milk and nipple discharge in the prediction of different breast diseases diagnoses. Methods Three hundred thirty-six patients (96 breast cancer and 240 benign disease patients) with nipple discharge and a control group of 56 healthy parturient participants were enrolled in the present study. Nipple discharge samples were preoperatively collected from the patients, and milk was collected from the colostrum of the parturient participants. The samples were assayed for the CEA, CA153 and CA125 levels. Cutoff values were determined for the detection of breast diseases using ROC curves. Results The levels of CEA, CA153 and CA125 were significantly different between the nipple discharge and the milk (all ps < 0.001). In the nipple discharge, the CEA and CA153 levels in the breast cancer group were significantly greater than those in the benign group (all ps < 0.001), and cutoff values of 263.3 ng/mL and 1235.3 U/mL, respectively, were established. However, the expression of CA125 did not differ significantly between the breast cancer and benign groups. Conclusion Differences in the apparent expression levels of CEA, CA153 and CA125 in patients with nipple discharge and healthy persons were validated. The present data suggest that CEA and CA153 might potentially be useful in the differential diagnoses of benign tumors and breast cancer. CA125 did not seem to be useful for breast cancer detection.

    Background This study aims to investigate differences between continuous epidural infusion (CEI) and programmed intermittent epidural bolus (IEB) analgesia for the Chinese parturients undergoing spontaneous delivery and to approach their safety to parturients and neonates. Methods Two hundred healthy American Society of Anesthesiologists class I or II, term (≥37 weeks’ gestation), nulliparous women who requested analgesia for labor were recruited. Epidural analgesia was initiated with a solution of 0.15% ropivacaine 10 mL and maintained with 0.1% ropivacaine mixed with sufentanil 0.3 μg/mL by CEI at a rate of 5 mL/h combined with a patient-controlled epidural analgesia (PCEA) bolus of 5 mL of ropivacaine sufentanil mixture or IEB of 5 mL of ropivacaine sufentanil mixture combined with a PCEA bolus of 5 mL of ropivacaine sufentanil mixture. The lockout interval was 20 minutes in each arm between the CEI and the IEB group. After 20 minutes of first dosage, visual analog scale (VAS) score was obtained every 60 minutes. The maternal and fetal outcome and total consumption of analgesic solution were compared. Results There was no difference in demographic characteristics, duration of first and second stages, delivery methods, sensory block, fetal Apgar scores, and the maternal outcomes between the CEI and IEB groups. There was a significant difference in VAS scores and epidural ropivacaine total consumption between the two groups (IEB vs CEI: 51.27±9.61 vs 70.44±12.78 mg, P<0.01). Conclusion The use of programmed IEB mixed with PCEA improved labor analgesia compared to CEI mixed with PCEA, which could act as maintenance mode for epidural labor analgesia. PMID:27471390

    Background Obesity is a nutritional disorder that is fast becoming a public health issue in the developing world. It is associated with increased incidence of maternal complications and adverse perinatal outcome. Methods and results This is a case-control study of obesity in pregnancy carried out in the maternity wing of University of Ilorin Teaching Hospital, Nigeria. The subjects and controls were 156 obese and 80 non-obese women booked at this hospital for antenatal care. The controls were matched for age and parity. Obesity occurred more commonly among the well educated (P = 0.00) and those in social classes I and II (P = 0.00). The occurrence of other medical conditions was not significantly different. The obese women also had more caesarean sections (P = 0.00), more assisted vaginal deliveries (P = 0.00) and fewer spontaneous vaginal deliveries (P = 0.00) than the non-obese parturients. The mean birth weight of infants of the obese mothers was 4.06 ± 0.13 kg (mean±SD) while the mean for the controls was 3.36 ± 0.49 kg. The difference was statistically significant (P = 0.000). Also, the obese parturients had more macrosomic babies (defined as birth weight >4.2 kg) than the non-obese (P = 0.00). The risks of perinatal asphyxia, birth trauma, neonatal admission and low birth weight were not increased among obese women in this study. Conclusion This study suggests that in our community, obesity occurs more commonly among women of high socioeconomic status and is a risk factor for maternal and fetal complications.

    Butorphanol is considered an effective and safe analgesic after cesarean delivery but is associated with profound dose-dependent sedation. Somnolence may cause hindrance in early mother-baby interaction. This study was designed to assess the analgesic efficacy and to monitor side-effects of low doses (0.5 mg and 0.75 mg) of epidural butorphanol with bupivacaine compared to bupivacaine alone in parturients following cesarean delivery. One hundred and twenty parturients (American Society of Anesthesiologists physical status 1 and 2) undergoing cesarean delivery were allocated into three groups: group 1 received epidural 0.125% bupivacaine while group 2 and 3 received an additional 0.5 mg and 0.75 mg butorphanol respectively. A combined spinal, epidural technique was used. Spinal anaesthesia was used for surgery. The epidural route was used for postoperative analgesia with the study drug. Onset, duration and quality of analgesia, lowest visual analogue scales (VAS) score, and side effects were noted. The onset and duration of analgesia in group 2 (4.1+/-2.6 min and 202.4+/-62.8 min) and group 3 (4.0+/-2.5 min and 192.3+/-69.1 min) were significantly different (P<0.01) from group 1 (6.6+/-2.7 min and 145.7+/-89.6 min). The quality of analgesia in terms of time to first independent movement and satisfactory VAS were statistically better (P<0.01) in group 2 (3.9+/-0.3 hour and 8.1+/-0.1 mm) and group 3 (3.8+/-0.4 hour and 8.1+/-0.9 mm) than in group 1 (5.2+/-0.4 hour and 6.3+/-1.3 mm). The incidence of sedation was 5% in all the three groups. A lower dose of epidural butorphanol with bupivacaine produces a significantly earlier onset, longer duration and better quality of analgesia than bupivacaine does. PMID:18709032

    Background and Aims: Computer-integrated patient-controlled epidural analgesia (CIPCEA) is a novel epidural drug delivery system. It automatically adjusts the basal infusion based on the individual's need for analgesia as labor progresses. Materials and Methods: This study compared the time-weighted local anesthetic (LA) consumption by comparing parturients using CIPCEA with no initial basal infusion (CIPCEA0) with CIPCEA with initial moderate basal infusion of 5 ml/H (CIPCEA5). We recruited 76 subjects after ethics approval. The computer integration of CIPCEA titrate the basal infusion to 5, 10, 15, or 20 ml/H if the parturient required respectively, one, two, three, or four patient demands in the previous hour. The basal infusion reduced by 5 ml/H if there was no demand in the previous hour. The sample size was calculated to show equivalence in LA consumption. Results: The time-weighted LA consumption between both groups were similar with CIPCEA0 group (mean [standard deviation (SD)] 8.9 [3.5] mg/H) compared to the CIPCEA5 group (mean [SD] 9.9 [3.5] mg/H), P = 0.080. Both groups had a similar incidence of breakthrough pain, duration of the second stage, mode of delivery, and patient satisfaction. However, more subjects in the CIPCEA0 group required patient self-bolus. There were no differences in fetal outcomes. Discussion: Both CIPCEA regimens had similar time-weighted LA consumption and initial moderate basal infusion with CIPCEA may not be required. PMID:25425774

    Background: The antiemetic efficacy of midazolam and ondansetron was shown before. The aim of the present study was to compare efficacy of using intravenous midazoalm, ondansetron, and midazolam in combination with ondansetron for treatment of nausea and vomiting after cesarean delivery in parturient underwent spinal anesthesia. Materials and Methods: One hundred thirty two parturients were randomly allocated to one of three groups: group M (n = 44) that received intravenous midazoalm 30 μg/kg; group O (n = 44) that received intravenous ondansetron 8 mg; group MO (n = 44) that received intravenous midazoalm 30 μg/kg combined with intravenous ondansetron 8 mg if patients had vomiting or VAS of nausea ≥ 3 during surgery (after umbilical cord clamping) and 24 hours after that. The incidence and severity of vomiting episodes and nausea with visual analog scale (VAS) > 3 were evaluated at 2 hours, 6 hours, and 24 hours after injection of study drugs. Results: The incidence of nausea was significantly less in group MO compared with group M and group O at 6 hours postoperatively (P = 0.01). This variable was not significantly different in three groups at 2 hours and 24 hours after operation. The severity of nausea and vomiting was significantly different in three groups at 6 hours after operation (P < 0.05). Conclusion: Our study showed that using intravenous midazolam 30 μg/kg in combination with intravenous ondansetron 8 mg was superior to administering single drug in treatment of emetic symptoms after cesarean delivery under spinal anesthesia.

    Psychotic disorders are currently grouped under broad phenomenological diagnostic rubrics. Researchers hope that progress in identifying aetiological mechanisms will ultimately enable more precise division of heterogeneous diagnoses into specific and valid subgroups. This goal has been an aim of psychiatry since the 19th century, when patients with general paresis were thought to have "insanity" similar to dementia praecox and manic depressive illness. Nowadays, the constructs of organic-induced and substance-induced psychotic disorder show that our diagnostic classification system already reflects, in part, aetiological factors. Most recently, gene copy number variation and autoimmunity have been associated with schizophrenia. We suggest how, on the basis of recent scientific advances, we can progress the identification of further putative subgroups and make the most of currently available interventions. Prompt diagnosis and treatment, and a more routine search for causes, could preserve function and improve outcome, and therefore be more acceptable to patients and carers. PMID:27063388

    We report the case of a 72-year-old man who had contracted acute paralytic poliomyelitis in his childhood. Thereafter, he had suffered from paresis involving the left lower limb, with no relapse or progression of the disease. He began noticing slowly progressive muscle weakness and atrophy in the upper and lower extremities in his 60s. At the age of 72, muscle weakness developed rapidly, and he demonstrated dyspnea on exertion and dysphagia. He died after about 14 years from the onset of muscle weakness symptoms. Autopsy findings demonstrated motoneuron loss and glial scars not only in the plaque-like lesions in the anterior horns, which were sequelae of old poliomyelitis, but also throughout the spine. No Bunina bodies, TDP-43, and ubiquitin inclusions were found. Post-polio syndrome is rarely fatal due to rapid progressive dyspnea and dysphagia. Thus, the pathological findings in the patient are considered to be related to the development of muscle weakness. PMID:26616485

    We report the case of a 64-year-old male presenting with a rapidly enlarging painful violaceous plaque in the left buttock and posterior thigh, following a gluteal intramuscular injection of benzathine penicillin. Associated urinary incontinence and lower left limb paresis were consistent with sciatic and lower sacral nerve damage, as confirmed by electromyography. Additional underlying muscular damage was observed in ultrasound and computer tomodensitometry scans and supported by high serum levels of creatine kinase and lactate dehydrogenase. Aggressive treatment was performed with fluid expansion, intravenous steroid bolus, vasodilators and anticoagulation, resulting in slow improvement of cutaneous and muscular lesions. However, no significant effect was observed on neurologic dysfunction after 6 months of regular neuromuscular rehabilitation. Nicolau Livedoid Dermatitis is a rare and potentially fatal condition showing variable levels of tissue impairment and unpredictable course and prognosis. Specific treatment is not consensual and the efficacy of any particular treatment remains to be established. PMID:21199637

Left lower lobe pulmonary infiltrate and/or atelectasis developed in 13 of 40 (32.5%) patients who were operated upon without topical cooling of the heart with ice, and in 77 of 122 (63.1%) patients in one group and 34 of 40 (85.0%) patients in another group who were operated upon with topical cooling of the heart with ice. This difference was highly significant (p<0.001). Of the patients in one group in whom left lower lobe abnormality developed, 69.2% had paralysis or paresis of the left hemidiaphragm. It is evident that application of ice to the phrenic nerve can lead to temporary paralysis of the left leaf of the diaphragm, with subsequent development of left lower lobe pulmonary infiltrate and/or atelectasis.

    A 59-year-old left-handed man presented with chest pain and hypertension and was found to have an acute descending aortic dissection on imaging. After thoracic endovascular repair of the dissection, he developed left arm weakness and ischemia. Despite carotid-subclavian transposition, the patient was found to have persistent left triceps weakness as well as bilateral leg paresis. An urgent spinal drain was placed that improved his lower extremity deficit but did not greatly change his arm symptoms. Magnetic resonance imaging of the spine revealed previously undiagnosed severe multilevel spinal stenosis requiring operative decompression. To our knowledge, this is the first report of the contribution of cervical spinal stenosis to post-thoracic endovascular repair spinal ischemia. PMID:25564598

  18. Does C5 or C6 Radiculopathy Affect the Signal Intensity of the Brachial Plexus on Magnetic Resonance Neurography?

    Patients with C5 or C6 radiculopathy complain of shoulder area pain or shoulder girdle weakness. Typical idiopathic neuralgic amyotrophy (INA) is also characterized by severe shoulder pain, followed by paresis of shoulder girdle muscles. Recent studies have demonstrated that magnetic resonance neurography (MRN) of the brachial plexus and magnetic resonance imaging (MRI) of the shoulder in patients with INA show high signal intensity (HSI) or thickening of the brachial plexus and changes in intramuscular denervation of the shoulder girdle. We evaluated the value of brachial plexus MRN and shoulder MRI in four patients with typical C5 or C6 radiculopathy. HSI of the brachial plexus was noted in all patients and intramuscular changes were observed in two patients who had symptoms over 4 weeks. Our results suggest that HSI or thickening of the brachial plexus and changes in intramuscular denervation of the shoulder girdle on MRN and MRI may not be specific for INA. PMID:27152289

    A 79-year-old woman was admitted to our hospital because of prolonged impaired consciousness and right hemiparesis. She was treated for acute cerebral infarction because her brain magnetic resonance imaging showed extensive cortical lesions similar to acute infarction in diffusion weighted image, fluid attenuated inversion recovery, and T2 weighted images. On the fifth day, she had a focal seizure on the right side. A new lesion during imaging and electroencephalogram abnormality were observed at that time. After the antiepileptic drug treatment was started, her right hemiparesis considered as ictal paresis, confusion, and the magnetic resonance imaging findings gradually improved. There was also an old, irreversible lesion in the left hippocampus, which was considered as the focus of her complex partial seizure. In the elderly, the post-ictal period of confusion, which occurs with complex partial seizure, may be prolonged. In our case, improvement of hemiparesis and confusion occurred after about 2 weeks.

    An adult pygmy African hedgehog developed acute posterior paresis attributed to a prolapsed intervertebral disc diagnosed by C-T scan. Corticosteroid therapy resulted in prompt resolution of the ataxia, but 2 weeks later the animal became anorexic and died. Macroscopically, the liver was stippled with punctate off-white foci which were confirmed microscopically to be foci of necrosis. Numerous hepatocytes contained intranuclear inclusions and syncytial cell formation was also present. A herpes virus was isolated and identified by fluorescent antibody and polymerase chain reaction studies as herpesvirus simplex type 1. To our knowledge, this is the first report of herpes infection in the African hedgehog and the first time herpes simplex has been identified as a cause of disease in insectivores. PMID:11814325

  1. Respiratory Management in the Patient with Spinal Cord Injury

    2013-01-01

    Spinal cord injuries (SCIs) often lead to impairment of the respiratory system and, consequently, restrictive respiratory changes. Paresis or paralysis of the respiratory muscles can lead to respiratory insufficiency, which is dependent on the level and completeness of the injury. Respiratory complications include hypoventilation, a reduction in surfactant production, mucus plugging, atelectasis, and pneumonia. Vital capacity (VC) is an indicator of overall pulmonary function; patients with severely impaired VC may require assisted ventilation. It is best to proceed with intubation under controlled circumstances rather than waiting until the condition becomes an emergency. Mechanical ventilation can adversely affect the structure and function of the diaphragm. Early tracheostomy following short orotracheal intubation is probably beneficial in selected patients. Weaning should start as soon as possible, and the best modality is progressive ventilator-free breathing (PVFB). Appropriate candidates can sometimes be freed from mechanical ventilation by electrical stimulation. Respiratory muscle training regimens may improve patients' inspiratory function following a SCI.

    We report the case of a 44-year-old male, lacking clinical history of previous illness, who had surgery at our hospital to treat a mass in the supraclavicular space. The patient presented with a 1-month progressive distal paresis of the left arm. The histo-pathological examination of the mass revealed an encapsulated fat necrosis. Fat necrosis is characterised by cystic architecture, encapsulation with fat necrosis within, and inflammatory infiltration of its walls. Neural structure compression secondary to this tumour mass is very rare. Fat necrosis is more frequent in the lower limbs, in areas exposed to trauma. This article is the first report of brachial plexus compression due to supraclavicular fat necrosis. PMID:24837841

    Endemic cretinism includes two syndromes: a more common neurological disorder with brain damage, deaf mutism, squint and spastic paresis of the legs and a less common syndrome of severe hypothyroidism, growth retardation and less severe mental defect. Both conditions are due to dietary iodine deficiency and can be prevented by correction of iodine deficiency before pregnancy. Endemic cretinism is now included in the spectrum of the effects of iodine deficiency in a population termed the 'iodine deficiency disorders (IDDs)', which also includes a wide range of lesser degrees of cognitive defect that can be prevented by the correction of iodine deficiency. Iodine deficiency is now recognised by the World Health Organization (WHO) as the most common preventable cause of brain damage with in excess of 2 billion at risk from 130 countries. A global United Nations (UN) programme of prevention has achieved 68% household usage of iodised salt by the year 2000 compared with less than 20% prior to 1990. PMID:20172469

    The veterinary records of three species of free-living, endangered black cockatoos (Calyptorhynchus spp.; n = 565) admitted to the Perth Zoo Veterinary Hospital in Western Australia during a 10-yr period (2000-09) were analyzed to determine the effect of clinical presentation and treatment on survival to release. The most-common reason for admission was trauma (at least 76.7% of cases), and trauma was also the most-frequent finding on necropsy examination (80.1% of cases). Anemia and paralysis-paresis were significant factors determining the decreased likelihood of survival of cockatoos undergoing rehabilitation. Human activities, in particular vehicle strike, were significant causes of morbidity and mortality in free-living black cockatoo populations. PMID:25647589

    The purpose of this review is to provide a comprehensive approach for assessing the upper extremity (UE) after stroke. First, common upper extremity impairments and how to assess them are briefly discussed. While multiple UE impairments are typically present after stroke, the severity of one impairment, paresis, is the primary determinant of UE functional loss. Second, UE function is operationally defined and a number of clinical measures are discussed. It is important to consider how impairment and loss of function affect UE activity outside of the clinical environment. Thus, this review also identifies accelerometry as an objective method for assessing UE activity in daily life. Finally, the role that each of these levels of assessment should play in clinical decision making is discussed in order to optimize the provision of stroke rehabilitation services. PMID:22975740

    A healthy 26-year-old man, without initially presenting fever, rapidly developed a focal right pontomedullary deficit associated with an aseptic lymphocytic meningitis. The diagnosis of Listeria infection was confirmed by blood cultures. CT and MRI demonstrated an abscess extending from the superior cerebellar peduncle to the lateral portion of the medulla. Immunological controls gave no indication of deficiency. With ampicillin therapy, started on the 5th day, clinical recovery was almost complete, but a soft palate right paresis persisted as the unique sequel. Antibiotic therapy was maintained for 5 months up to normal CSF and CT. One year after the onset, MRI was also normal. The rare nature of listerial abscess in the brainstem is discussed with regard to rhombencephalitides. PMID:2727539

    The reflexlocomotion acc. to VOJTA is a neurophysiologic facilitation system for the whole CNS and neuromuscular apparatus. It consists of all components, in a reciprocal manner of locomotion: (i) automatic control of posture, (ii) uprighting, (iii) aimed movements. Consequently the indications for this type of kinesiologic facilitation are really extensive. In this article the following complete list of indications is described: CCD (central coordination disorder), CP (cerebral palsy), peripheral paresis, Spina bifida (MMC), Myopathies, congenital malformations, orthopaedic problems, traumatic cross sections, neuromuscular dysfunctions etc. Further the experiences of the treatment in each disease are discussed. Even EMG-detections have shown the effect of the therapy in peripheral and central damage. Therefore a good prognosis for improvement and rehabilitation can be given in a large number of disorders, irrespective of age. PMID:1535338

    We describe a case of intra-arterial treatment (IAT) of acute posterior circulation occlusion in a patient with a persistent primitive trigeminal artery (PPTA). The patient presented with an acute left sided hemiparesis and loss of consciousness (Glasgow coma score of 5). Computed tomography angiography showed an acute occlusion of the right internal carotid artery (ICA), the PPTA, distal basilar artery (BA), right posterior cerebral artery (PCA), and right superior cerebellar artery (SCA). Stent-retriever assisted thrombectomy was not considered possible through the hypoplastic proximal BA. After passage of the proximal ICA occlusion, the right PCA and SCA were recanalized through the PPTA, with a single thrombectomy procedure. Ten days after intervention patient was discharged scoring optimal EMV with only a mild facial and left hand paresis remaining. PPTA is a persistent embryological carotid-basilar connection. Knowledge of existing (embryonic) variants in neurovascular anatomy is essential when planning and performing acute neurointerventional procedures. PMID:26464287

    Abstract Diaphragmatic paresis is a rare but recognized complication of atrial fibrillation ablation. A 59-year-old woman experiencing dyspnea in supine position and for minimal effort was admitted in a cardiac rehabilitation center. One month before, she was referred to a cardiac center to ablation of paroxysmal atrial fibrillation. After the procedure, the patient developed respiratory failure attributed to aspiration pneumonia and requiring mechanical ventilation. At admission in the rehabilitation center, M-mode ultrasonography reported an absence of movement of the right hemidiaphragm during quiet breathing and a paradoxical movement during voluntary sniffing. Chest ultrasonography can be useful to detect diaphragmatic dysfunction in patients suffering from dyspnea, at admission in a cardiac rehabilitation center. Its use should be envisaged more frequently. PMID:25984664

    Patient: Male, 17 Final Diagnosis: Burkitt lymphoma Symptoms: Anisocoria, ipsilateral ptosis, opthalmoparesis, paresis Medication: — Clinical Procedure: — Specialty: Oncology Objective: Unusual clinical course Background: Burkitt lymphoma rarely affects the central nervous system and ocular region. Under these conditions, computed tomography and (particularly) magnetic resonance imaging of the skull increase the diagnostic accuracy, as they objectively show the topography of lesions and the effect of neoplasia on structures. Case Report: We report here the case of a 17-year-old male whose initial clinical manifestations were related to neurological impairment and to the ocular musculature and ocular innervation. The diagnosis of Burkitt lymphoma with leukemization and infiltration of the central nervous system was confirmed. Conclusions: In this case, it is important to recognize that the neuroimaging findings were fundamentally important in indicating the initial form of the disease and in directing the appropriate clinical management.

    2014-01-01

    Varicella zoster virus (VZV) is an exclusively human neurotropic alphaherpesvirus. Primary infection causes varicella (chickenpox), after which the virus becomes latent in ganglionic neurons along the entire neuraxis. With advancing age or immunosuppression, cell-mediated immunity to VZV declines, and the virus reactivates to cause zoster (shingles), dermatomal distribution, pain, and rash. Zoster is often followed by chronic pain (postherpetic neuralgia), cranial nerve palsies, zoster paresis, vasculopathy, meningoencephalitis, and multiple ocular disorders. This review covers clinical, laboratory, and pathological features of neurological complications of VZV reactivation, including diagnostic testing to verify active VZV infection in the nervous system. Additional perspectives are provided by discussions of VZV latency, animal models to study varicella pathogenesis and immunity, and of the value of vaccination of elderly individuals to boost cell-mediated immunity to VZV and prevent VZV reactivation.

    Studying eye movements and vestibular function would provide insights into brain networks that are vulnerable in mitochondrial disorders. We sought eye movement and vestibular abnormalities in three Korean patients with a mitochondrial A3243G point mutation. The patients suffered from vertigo and imbalance during the stroke-like and seizure episodes from lesions involving the posterior cerebral cortex, which were accompanied by bilateral saccadic hypermetria and horizontal gaze-evoked nystagmus. Furthermore, two patients showed bilateral impairments of the vestibulo-ocular reflex during head impulses for the horizontal and posterior canals on both sides in the absence of caloric paresis. Cerebellar atrophy was prominent on MRIs in two patients and was less marked in the other patient. These findings imply that the cerebellum is susceptible to neuronal energy deficiency due to mitochondrial A3243G point mutation. PMID:27075643

    1992-01-01

    We injected botulinum toxin into the horizontal rectus muscles of the right eyes of two patients who had acquired pendular nystagmus with horizontal, vertical, and torsional components. This treatment successfully abolished the horizontal component of the nystagmus in the injected eye in both patients for approximately 2 months. Both patients showed a small but measurable improvement of vision in the injected eye that may have been limited by coexistent disease of the visual pathways. The vertical and torsional components of the nystagmus persisted in both patients. In one patient, the horizontal component of nystagmus in the noninjected eye increased; we ascribe this finding to plastic-adaptive changes in response to paresis caused by the botulinum toxin. Such plastic-adaptive changes and direct side effects of the injections - such as diplopia and ptosis - may limit the effectiveness of botulinum toxin in the treatment of acquired nystagmus. Neither patient elected to repeat the botulinum treatment.

    Spontaneous spinal hemorrhage is a rare condition. We present a case in which the diagnosis was complicated by a concomitant intra-abdominal hemorrhage. The patient, taking coumarins, presented with acute back pain and abdominal pain and progressive paresis of the lower limbs. Computed tomography angiography of the abdomen showed an intra-abdominal hemorrhage and an aneurysm of the celiac trunk. MR (magnetic resonance) imaging of the spine revealed a combined subdural and epidural hemorrhage from C1 to L1. Both sites were treated conservatively. After 6 months the patient regained strength in both legs with some persistent loss of strength in the left leg. Follow-up MR imaging showed complete resolution of the spinal hemorrhage. The celiac artery aneurysm was treated conservatively. We suggest that the rupture of the celiac artery aneurysm caused increased intra-abdominal pressure leading to spinal hemorrhage. Emergency staff should be aware of the possibility of two rare but concomitant conditions. PMID:26251805

    A 9 yr old castrated male golden retriever weighing 36 kg was presented for evaluation of progressive left pelvic limb paresis and fecal and urinary incontinence. MRI demonstrated an extradural, ovoid mass compressing the lumbar spinal cord. Surgical excision of the mass was performed. Histologically, the mass was consistent with hemangiosarcoma with no involvement of the adjacent vertebrae. The dog underwent a doxorubicin-based chemotherapy protocol with the addition of oral cyclophosphamide. After completion of chemotherapy, the dog was evaluated q 4 mo for restaging. Clinicopathological evidence of primary tumor recurrence or metastatic disease was not detected for 15 mo after initial diagnosis and treatment. To the authors' knowledge, this is the first report of a primary extradural hemangiosarcoma in the lumbar vertebral column in a dog. The clinical presentation, diagnosis, treatment, and outcome are also discussed. PMID:25955146

    This study describes an occurrence of pink morning glory (Ipomoea carnea) intoxication in goats in northern Argentina. The clinical signs displayed by the affected animals were ataxia, lethargy, emaciation, hypertonia of the neck muscles, spastic paresis in the hind legs, abnormal postural reactions and death. The clinico-pathologic examination revealed that the affected animals were anemic and their serum level of aspartate aminotransferase was significantly increased. Cytoplasmic vacuolation in the Purkinje cells and pancreatic acinar cells was observed by histological examination. The neuronal lectin binding pattern showed a strong positive reaction to WGA (Triticum vulgaris), sWGA (succinylated T. vulgaris) and LCA (Lens culinaris). Although I. carnea is common in tropical regions, this is the first report of spontaneous poisoning in goats in Argentina. PMID:25728544

    Pineal cysts are usually asymptomatic; however, they may rarely cause symptoms such as chronic headache, paroxysmal headache with gaze paresis, postural syncope, loss of consciousness, and sudden death. A 30-year-old woman with no specific medical history except chronic headache was found collapsed in a public toilet per se. Postmortem examination revealed no external injuries or internal diseases except a cystic lesion of the pineal gland. Histologic examination showed an internal cyst surrounded by glial tissues and pineal parenchyma that was diagnosed as a glial cyst of the pineal gland. Although the pineal cyst cannot be confirmed as the cause of death, it was considered, as no other cause was evident. Herein, we report a pineal cyst considered as an assumed cause of death.

    Eight consecutive patients with CT scan evidence of a bilateral infarct in the territory of the paramedian thalamic artery are reported. In seven cases the infarct also extended to the territory of the polar artery. The main symptoms were: disorder of vigilance which cleared in a few days, and hypersomnolence which lasted longer and in two patients was still present a year later; amnesia, detectable clinically in four patients and only with tests in two patients, which persisted in one patient for three years; changes of mood and bulimia present in five and four patients respectively; and vertical gaze paresis in five patients. Only one patient died, and in the remainder the symptoms tended to subside, but none of the patients who could be followed-up for a year returned to normal behaviour. Clinical and CT scan correlations pointed to the mammillo-thalamic tract as the structure whose damage was responsible for the memory disorders. Images PMID:3625213

    Mononeuropathy after surgery may occur and hereditary neuropathy with liability to pressure palsies is a possible pathological condition related to paresis after hip surgery. We present a case of 66-year-old man presenting severe weakness at inferior limb muscles after hip prosthesis revision. Clinic and electrophysiology showed severe right fibular nerve damage and ultrasound found a marked enlargement of the same nerve, associated with focal enlargements in other nerves. A diagnosis of hereditary neuropathy with liability to pressure palsies was suspected and confirmed by genetic test. The patient gradually recovered returning to a normal daily active life. Ultrasound was crucial for diagnosis. The suspicion and diagnosis of latent neuropathy, which can occur after surgical intervention, may lead to a better understand of the risks of the surgery, specific for the patient, and avoid the wrong attribution to surgical malpractice.

On full ear, nose and throat examination, he was found to have fixed vocal cords with pooling of saliva in the bilateral pyriform fossa. Hypopharyngeal malignancy was suspected and further imaging was performed. Imaging also raised the suspicion of malignancy in the hypopharynx. Rigid endoscopic examination under general anaesthesia was carried out which revealed an impacted denture in the cricopharynx and upper oesophagus. The patient was aware of his loss of dentures 3 months ago (corresponds to the onset of his symptoms) but felt that he had mislaid them and had never mentioned this to anyone. We present a case highlighting a delay in diagnosis, a missed diagnosis on CT scan and an unusual presentation leading to bilateral vocal cord paresis. PMID:25139929

    Among the distal anterior inferior cerebellar artery (AICA) aneurysms, a unique aneurysm at the meatal loop inside the internal auditory meatus is extremely rare. The authors report a case of surgically treated total intrameatal AICA aneurysm. A 62-year-old female patient presenting with sudden bursting headache and neck pain was transferred to our department. Computed tomography and digital subtraction angiography showed subarachnoid hemorrhage at the basal, prepontine cistern and an aneurysm of the distal anterior inferior cerebellar artery inside the internal auditory meatus. Surgery was performed by retrosigmoid craniotomy with unroofing of the internal auditory meatus. The aneurysm was identified between the seventh and eighth cranial nerve in the meatus and was removed from the canal and clipped with a small straight Sugita clip. After operation the patient experienced transient facial paresis and tinnitus but improved during follow up. PMID:26361531

    Progressive supranuclear palsy (PSP) is a progressive neurodegenerative disorder, characterized by motor symptoms, postural instability, personality changes, and cognitive impairment. There is no effective treatment for this disorder. Reduced neurotransmission of GABA in the striatum and globus pallidus may contribute to the symptoms of motor and cognitive symptoms seen in PSP. Zolpidem is a GABA agonist of the benzodiazepine subreceptor BZ1. Here a nondiabetic, normotensive case of PSP is (Progressive Supranuclear Palsy) described, which showed improvement in swallowing, speech, and gaze paresis after zolpidem therapy and possible mechanism of actions are discussed. However, more trials are needed with large number of patients to confirm the effectiveness of zolpidem in progressive supranuclear palsy. PMID:23762677

    2014-04-01

    Advanced imaging techniques, improved operative techniques, and instrumentation combined with better patient awareness and expectations have resulted in an exponential increase in upper limb surgical procedures during recent times. Surgical teams expect superior analgesia and regional blocks have matched these expectations quite often resulting in improved patient satisfaction and early rehabilitation to achieve best results. Ultrasound-guided interscalene brachial plexus block (ISB) is commonly used to provide analgesia for procedures involving shoulder girdle. We report a case of symptomatic hemi-diaphragmatic paresis (HDP) due to the phrenic nerve block following ISB for arthroscopic sub-acromial decompression of the shoulder presenting as severe postoperative dyspnea. There is strong evidence of HDP following ISB in anesthetic literature, but not reported in related surgical specialties such as orthopedics. We wish to inform upper-limb surgeons and educate junior doctors and other ancillary staff working in upper-limb units to be aware of this serious but reversible complication. PMID:25114416

  4. Nonlinear dynamic mechanism of vocal tremor from voice analysis and model simulations

    2008-09-01

    Nonlinear dynamic analysis and model simulations are used to study the nonlinear dynamic characteristics of vocal folds with vocal tremor, which can typically be characterized by low-frequency modulation and aperiodicity. Tremor voices from patients with disorders such as paresis, Parkinson's disease, hyperfunction, and adductor spasmodic dysphonia show low-dimensional characteristics, differing from random noise. Correlation dimension analysis statistically distinguishes tremor voices from normal voices. Furthermore, a nonlinear tremor model is proposed to study the vibrations of the vocal folds with vocal tremor. Fractal dimensions and positive Lyapunov exponents demonstrate the evidence of chaos in the tremor model, where amplitude and frequency play important roles in governing vocal fold dynamics. Nonlinear dynamic voice analysis and vocal fold modeling may provide a useful set of tools for understanding the dynamic mechanism of vocal tremor in patients with laryngeal diseases.

    We present a virtual reality (VR)-based motor neurorehabilitation system for stroke patients with upper limb paresis. It is based on two hypotheses: (1) observed actions correlated with self-generated or intended actions engage cortical motor observation, planning and execution areas ("mirror neurons"); (2) activation in damaged parts of motor cortex can be enhanced by viewing mirrored movements of non-paretic limbs. We postulate that our approach, applied during the acute post-stroke phase, facilitates motor re-learning and improves functional recovery. The patient controls a first-person view of virtual arms in tasks varying from simple (hitting objects) to complex (grasping and moving objects). The therapist adjusts weighting factors in the non-paretic limb to move the paretic virtual limb, thereby stimulating the mirror neuron system and optimizing patient motivation through graded task success. We present the system's neuroscientific background, technical details and preliminary results. PMID:17687578

    Herpes zoster develops by endogenous reactivation of varizella zoster virus (VZV). Incidence increases with age. Females are more frequently affected than males. The reactivation rate in seropositive individuals is about 20 %. After a short prodromal stage, herpetiform-grouped vesicles appear in segmental arrangement. Pain and paresthesia are typical zoster symptoms. Complications like bacterial superinfections, vasculopathy, paresis, and oculopathy may occur. During pregnancy herpes zoster is a threat for mother and child. Among elderly patients, cardiovascular risk is increased during the first week of herpes zoster infection. Postherpetic neuropathy is feared. Diagnosis can be made clinically and by the use of polymerase chain reaction. First-line treatment is systemic antiviral drug therapy with either acyclovir or brivudine. Adjuvant therapies consist of pain management and topical treatment. PMID:27389412

    A 4-year-old, 40-kg, male, entire Dalmatian was presented for evaluation of chronic neck pain and pelvic limb ataxia. Myelography revealed ventrodorsal (hourglass) extradural compression over the intervertebral space between the 5th and 6th cervical vertebra and ventral extradural compression between the 6th and 7th cervical vertebra. Cranial compression disappeared and caudal compression markedly diminished after performing cervical traction. MRI scan confirmed protrusion of intervertebral discs and spinal cord compression in previously mentioned intervertebral spaces. Surgical distraction-stabilization of both intervertebral spaces was performed using threaded pins and polymethylmethacrylate. The convalescence from surgery was uneventful and the dog was walking without any signs of paresis until 5 months after surgery when radiography revealed implants loosening. The dog recovered fully of the implant removal and remained asymptomatic for more than 30 months. PMID:23644293

    In this work dedicated to Frederic Nietzsche, we were first interested by the philosopher's personal psychopathology. Biographic and personality factors, the physical and moral pain, the mood variations, hypersensitivity, solitude and finally megalomanic traits have probably contributed to the development of his thought. Nietzsche gave personal interpretations of his own suffering. Freud himself recognized the organic component of the philosopher's illness. We reviewed the different symptoms in favor of a progressive general paresis. Philologist and moralist, Nietzsche was also a "psychologist". His intuitions in this area often preceded and prepared those of Freud. The relationship is surprising on certain points such as love and sexuality, the unconscious, the interpretation of dreams. We wish to remind readers that a prepsychoanalytic stream of thought, at the end of the 19th century, preceded the teaching now ascribed to Freud and his followers. PMID:7598351

    Friedrich Nietzsche (1844-1900) was a remarkable philologist-philosopher while remaining in a condition of ill-health. Issues about his wandering/disruptive behavior that might be a consequence and/or protection against his cognitive decline and multifaceted disease are presented. The life complex that raises speculations about its etiology is constituted by: insight, creativity and wandering behavior besides several symptoms and signs of disease(s), mainly neurological one. The most important issue to be considered at the moment is not the disease diagnosis (Lissauer's general paresis or CADASIL, e.g.), but the probable Nietzsche's great cognitive reserve linked to the multifactorial etiology (genetic and environmental), and shared characteristics both to creativity and psychopathology. This makes any disease seems especial regarding Nietzsche, and whichever the diagnostic hypothesis has to consider the Nietzsche's unique background to express any disease(s). PMID:26517222

    Anterior neck masses in young children can be a diagnostic challenge for otolaryngologists and radiologists. We present a rare case of herniation of normal mediastinal thymus in a four-year-old girl. Additional medical features as an inguinal hernia and trochlear nerve paresis raised the question whether there is a causal relationship or an association. A connective tissue disorder could not be diagnosed as possible causal factor to the abnormal movement of the mediastinal thymus. Awareness and recognition of this benign phenomenon is important in order to avoid unnecessary biopsy or surgery. Diagnosis can be confirmed by ultrasonography. Magnetic Resonance Imaging might be valuable in order to obtain more information about the extension of the mass. PMID:26968057

    We report the case of a 49-years-old patient who presented to the accident and emergency department with sudden onset dyspnea associated with acute shoulder pain. He was breathless at rest with supine hypoxemia. He had an amyotrophic left shoulder with localized paresis of the shoulder. Both hemi-diaphragms were elevated on chest X-rays. Pulmonary function tests showed a restrictive pattern and both phrenic nerve conduction velocities were decreased. At night, alveolar hypoventilation was evidenced by elevated mean capnography (PtcCO2: 57mmHg). Neuralgic amyotrophy, Parsonage-Turner syndrome was the final diagnosis. This syndrome is a brachial plexus neuritis with a predilection for the suprascapular and axillary nerves. Phrenic nerve involvement is rare but where present can be the most prominent clinical feature as in our case report. PMID:25534571

    Brachioradial pruritus is a chronic sensory neuropathy of unknown etiology which affects the skin of the shoulders, arms and forearms on the insertion of the brachioradialis muscle. We describe the case of a 60-yearold woman recently diagnosed with multiple myeloma who refers paresis, severe pruritus and itching lesions on the right arm with 6 months of evolution. Investigation led to a diagnosis of Brachioradial pruritus consequent to the presence of cervical disc herniation and Parsonage-Turner syndrome. The patient started gabapentin 900mg/day with good control of itching. Corticosteroids and antihistamines are often ineffective in the treatment of BP. Gabapentin has been used with encouraging results. All patients with Brachioradial pruritus should be evaluated for cervical spine injuries. PMID:26131874

    Varicella zoster virus (VZV) causes the common childhood disease chickenpox (varicella), or upon reactivation, the dermatomal vesiculopustular eruption seen in shingles (herpes zoster). The clinical course of herpes zoster in immunocompromised patients is often recurrent, protracted and multidermatomal, and it can result in myelitis, meningoencephalitis, and cerebral or small-vessel vasculopathic or vasculitic changes. Commonly, the vesicular rash settles with aciclovir therapy and does not involve motor neuropathy. We report a 63-year-old man with a prolonged, multidermatomal, nonvesicular rash, and limb paresis secondary to brachioplexitis. PCR for VZV was positive, and the histological results were consistent with granulomatous vasculopathy. Prolonged treatment with valaciclovir was required to resolve the eruption and help improve the patient's motor function. We discuss the problems faced in clinical decision-making about immunosuppressive treatment of granulomatous vasculopathy and motor neuropathy, when any increase in immunosuppressive therapy may increase the likelihood of central nervous system complications.

    Neuralgic amyotrophy (NA) is a distinct peripheral nervous system (PNS) disorder characterized by sudden attacks of neuropathic pain, usually in a unilateral upper extremity, and patchy paresis with atrophy in the glenohumeral muscles. The lesion sites of NA are commonly considered to be upper brachial plexus (BP) and/or individual branches of the BP. The cause of NA remains unknown. Some evidence suggests a complex pathogenesis in NA that includes predisposition and susceptible PNS structures, and it can be triggered by infection, trauma, and strenuous exercise. NA is considered to be broad and encompasses a spectrum of atypical presentations, including involvement of the lower part of the BP, isolated nerves (anterior interosseous nerve or posterior interosseous nerve), or lumbosacral plexuses. Functional prognosis of NA is less favorable than previously assumed; however, specific therapy for patients with NA remains to be established. PMID:25475029

    Neuralgic Amyotrophy (NA) is a rare disturb of the peripheral nervous system that can include extreme pain, multifocal paresis and atrophy of the muscles of the upper limbs. When the nerves located outside of the brachial plexus are involved, the term Neuralgic Amyotrophy Extended (ANE) is used. Diagnosis of NA is clinical and has a series of inclusion and compatibility criteria established by the European CMT Consortium. On this study the clinical history, multidimensional vocal assessment data and the vocal techniques used in five-weeks voice therapy for one patient, professional voice, with ANE are presented. In this case, sudden and recurrent paralysis of his right vocal fold was the only manifestation of the disease. At the end of the fifth week the patient's voice was normal, the spoken and sung vocal ranges were same as before the current episode of ANE and scores of his vocal self-assessment were appropriate.

Despite several orthopedic consultations and two cycles of physical therapy, the symptoms deteriorated over a period of 6 months, and progressive paresis of the extensor muscles of the upper limb and elbow flexion contracture were observed. On the basis of the clinical presentation and results of medical tests including an electrophysiological study that showed axonal damage to the long thoracic nerve, axillary nerve, and posterior interosseous nerve, neuralgic amyotrophy was diagnosed. A treatment with prednisone was introduced, and the patient's condition significantly improved. PMID:26817357

    Progressive, atrophic, asymmetrically distributed flaccid paresis of arm and hand muscles represents a frequent symptom of neuromuscular diseases that can be attributed to injury of the arm nerves, the plexus or the cervical roots. A timely and exact diagnosis is mandatory; however, the broad spectrum of differential diagnoses often represents a diagnostic challenge. A large variety of neuromuscular disorders need to be considered, encompassing autoimmune mediated inflammatory neuropathic conditions, such as multifocal motor neuropathy, as well as chronic degenerative and nerve compression disorders. This review provides an overview of the most frequent disorders of the upper plexus and cervical roots and summarizes the characteristic clinical features as well as electrodiagnostic and laboratory test results. In addition the diagnostic value of magnetic resonance imaging and sonography is discussed. PMID:24343110

    In December 2005 three sheep, originating from Canton Tessin, were presented with cerebrospinal nematodosis. The animals had a history of progressive pelvic limb ataxia and recumbency. The most important clinical findings were an abnormal gait (wide stance, pelvic limb paresis) and decreased sensitivity of the pelvic limbs. The general condition was slightly or moderately disturbed, appetite was normal. Examination of the cerebrospinal fluid revealed mononuclear cells and eosinophils, suggesting a helminthic infection of the central nervous system. Postmortem findings confirmed the clinical diagnosis in one animal as parts of a nematode were found in the thoracic spinal cord. Even though the nematode could not be identified, infection with Elaphostrongylus cervi seems very likely, as the sheep are in close contact with deer on the pastures and the parasite is known to infect goats in Switzerland. This is the first description of cerebrospinal nematodosis in sheep in Switzerland. PMID:17209510

    This study describes an occurrence of pink morning glory (Ipomoea carnea) intoxication in goats in northern Argentina. The clinical signs displayed by the affected animals were ataxia, lethargy, emaciation, hypertonia of the neck muscles, spastic paresis in the hind legs, abnormal postural reactions and death. The clinico-pathologic examination revealed that the affected animals were anemic and their serum level of aspartate aminotransferase was significantly increased. Cytoplasmic vacuolation in the Purkinje cells and pancreatic acinar cells was observed by histological examination. The neuronal lectin binding pattern showed a strong positive reaction to WGA (Triticum vulgaris), sWGA (succinylated T. vulgaris) and LCA (Lens culinaris). Although I. carnea is common in tropical regions, this is the first report of spontaneous poisoning in goats in Argentina. PMID:25728544

    Two outbreaks of progressive hind limb paresis in cats (Felis catus) caused by parasitic meningomyelitis in Uruguay are reported. The case studies occurred in 2008 and 2009 respectively, in the rural areas of Fray Bentos (33° 07' 40.39'' S) and were characterized by hindquarter paralysis. This paralysis was progressive and had a chronic progression of approximately 12 months until the death or euthanasia of the animals. Clinical symptoms started with ataxia of the hindquarters with lateral side-to-side swaying and culminated in total paralysis. Two animals were sent for necropsy in 2009. The main histopathological findings were severe myelitis in the lumbar spinal cord with perivascular cuffing and white matter necrosis, severe nonsuppurative meningitis with thrombi in subarachnoid blood vessels, and intravascular presence of multiple adult parasites. From the morphological characteristics of the parasites and location in the leptomeninges, the parasite was identified as the nematode Gurltia paralysans. PMID:21961761

    The dislocated hip in a non-ambulatory child with spastic paresis tends to be a painful interference to sleep, sitting upright, and perineal care. Proximal femoral resection-interposition arthroplasty is one method of treatment for this condition. We reviewed eight hips, two bilateral cases, with a mean follow-up of 30 months. Clinical improvement was observed in all except one case, with respect to pain relief and sitting tolerance. Some proximal migration was observed in three cases, despite routine post-operative skeletal traction in all cases and careful soft tissue interposition. One case showed significant heterotopic ossification which restricted prolonged sitting. This patient needed some occasional medication for pain. PMID:12180614

    Hoarseness of voice due to vocal cord paresis as a result of recurrent laryngeal nerve palsy has been well recognised. Recurrent laryngeal nerve palsy is commonly caused by compression due to tumour or lymph nodes or by surgical damage. Vinca alkaloids are well known to cause peripheral neuropathy. However, vinca alkaloids causing recurrent laryngeal nerve palsy has been reported rarely in children. We report a case of an adult patient with HIV who developed hoarseness of voice due to vocal cord paralysis during vinblastine treatment for Hodgkin lymphoma. Mediastinal and hilar lymph node enlargement in such patients may distract clinicians from considering alternative causes of recurrent laryngeal nerve palsy, with potential ensuing severe or even life-threatening stridor.

    A severe neurotoxicosis, comprising tremors, ataxia, paresis, recumbency and death, occurred simultaneously among several herds of beef cattle in the region of Flanders (Belgium). After a first multi-toxin screening of some suspected diet elements, verruculogen was detected in a sample of a common feed ingredient. However, when the first animal necropsies revealed serious nervous lesions, including neuronal degeneration of the central nervous system and axonal degeneration in the peripheral nervous system, further investigations focused on fungal isolation. As expected from the pathological lesions, Aspergillus clavatus was found to be the dominant fungal species in a sample of compacted fodder, containing malting residues, consumed by all the affected herds. The isolated fungus appeared to produce patulin in culture medium. Traces of patulin were also detected in the fodder. These findings and their possible role in the intoxication are discussed.

    Summary: Facial nerve paralysis because of penetrating trauma through the external auditory canal is extremely rare, with a paucity of published literature. The objective of this study is to review the literature on transtympanic facial nerve paralysis and increase physician awareness of this uncommon injury through discussion of its clinical presentation, management and prognosis. We also aim to improve patient outcomes in those that have sustained this type of injury by suggesting an optimal management plan. In this case report, we present the case of a 46-year-old white woman who sustained a unilateral facial nerve paresis because of a garfish penetrating her tympanic membrane and causing direct damage to the tympanic portion of her facial nerve. On follow-up after 12 months, her facial nerve function has largely returned to normal. Transtympanic facial nerve paralysis is a rare injury but can have a favorable prognosis if managed effectively. PMID:26090278

    The incidence of postoperative hemorrhage following thyroid surgery stands at 1%-2 %. This low incidence contrasts with the significant potential complications of postoperative hemorrhage. Influencing factors and measures mentioned in the literature and own studies are discussed. Although an improvement in the postoperative hemorrhage rate was to be expected indirectly due to the increasing use of coagulation-relevant medication, there has been neither an increase in incidence nor a reduction in resultant complications, including primarily recurrent vocal cord paresis, tracheotomy and mortality. Factors that influence surgical success include a meticulous technique and caution, as well as ensuring intensive and qualified postoperative monitoring for a minimum of 4-6 h, thereby permitting immediate revision surgery at any time.

    Thrombosis can affect any venous circulation. Venous thromboembolism (VTE) includes deep-vein thrombosis of the leg or pelvis, and its complication, pulmonary embolism. VTE is a fairly common disease, particularly in older age, and is associated with reduced survival, substantial health-care costs, and a high rate of recurrence. VTE is a complex (multifactorial) disease, involving interactions between acquired or inherited predispositions to thrombosis and various risk factors. Major risk factors for incident VTE include hospitalization for surgery or acute illness, active cancer, neurological disease with leg paresis, nursing-home confinement, trauma or fracture, superficial vein thrombosis, and—in women—pregnancy and puerperium, oral contraception, and hormone therapy. Although independent risk factors for incident VTE and predictors of VTE recurrence have been identified, and effective primary and secondary prophylaxis is available, the occurrence of VTE seems to be fairly constant, or even increasing.

    Patients with C5 or C6 radiculopathy complain of shoulder area pain or shoulder girdle weakness. Typical idiopathic neuralgic amyotrophy (INA) is also characterized by severe shoulder pain, followed by paresis of shoulder girdle muscles. Recent studies have demonstrated that magnetic resonance neurography (MRN) of the brachial plexus and magnetic resonance imaging (MRI) of the shoulder in patients with INA show high signal intensity (HSI) or thickening of the brachial plexus and changes in intramuscular denervation of the shoulder girdle. We evaluated the value of brachial plexus MRN and shoulder MRI in four patients with typical C5 or C6 radiculopathy. HSI of the brachial plexus was noted in all patients and intramuscular changes were observed in two patients who had symptoms over 4 weeks. Our results suggest that HSI or thickening of the brachial plexus and changes in intramuscular denervation of the shoulder girdle on MRN and MRI may not be specific for INA. PMID:27152289

    Diplodiosis is a neuromycotoxicosis of cattle and sheep caused by ingestion of maize infected with the ear-rot fungus Stenocarpella (= Diplodia ) maydis . Apart from ataxia, paresis, and paralysis, the toxin is responsible for stillbirths and neonatal losses characterized by the presence of spongiform degeneration in the white matter of the brain in the offspring of dams exposed to infected maize cobs. In the present study a toxin, named diplonine, which induced neurological signs in guinea pigs resembling some of those occurring in cattle and sheep, was isolated from S. maydis cultures. Purification of diplonine was achieved by methanol extraction followed by chromatographic separation on silica gel and RP-18 stationary phases. The structure and relative configuration of diplonine were defined by analysis of NMR and MS data as (S)-2-amino-2-[(1R,2S)-1-hydroxy-2-methylcyclopropyl]acetic acid or the (S)-2-amino-2-[(1S,2R)-diastereomer.

    Recurrent outbreaks of marine pufferfish poisoning in Bangladesh highlight the need to understand the context in which the outbreaks occurred. In a recent outbreak investigation, a multidisciplinary team conducted a mixed-method study to identify the demography and clinical manifestation of the victims and to explore different uses of pufferfish, and local buying, selling, and processing practices. The outbreak primarily affected a low income household where an elderly woman collected and cooked pufferfish egg curry. Nine persons consumed the curry, and symptoms developed in 6 (67%) of these persons. Symptoms included vomiting, diarrhea, paresis, and tingling sensation; 2 (22%) persons died. The unstable income of the affected family, food crisis, and the public disposal of unsafe pufferfish byproducts all contributed to the outbreak. A multi-level intervention should be developed and disseminated with the participation of target communities to discourage unsafe discarding of pufferfish scraps and to improve the community knowledge about the risk of consuming pufferfish.

    Two boa constrictors (Boa constrictor imperator) presented with paresis of the trunk originating cranial to the cloaca. Radiographs were consistent with proliferative bone lesions involving several vertebrae. Computed tomography (CT) demonstrated the presence of lytic/expansile lesions. Computed tomography-guided biopsies of the lesions were performed without complications. Histology was consistent with bacterial osteomyelitis and osteoarthritis. Gram-negative bacteria (Salmonella sp. and Pseudomonas sp.) were isolated from cultures of the biopsies. Medical treatment with specific antibiotics was attempted for several weeks in both cases without clinical or radiographic improvements. The animals were euthanized, and necropsy confirmed the findings observed upon CT. To the authors' knowledge, this is the first report of the use of CT-guided biopsies to evaluate proliferative vertebral lesions in snakes. In the present report, CT-guided biopsies were easily performed, and both histologic and microbiologic results were consistent with the final diagnosis. PMID:25632696

    OBJECTIVE. This study explored how upper-extremity (UE) functional capacity and daily performance change during the course of outpatient rehabilitation in people with stroke. METHOD. Fifteen participants receiving outpatient occupational therapy services for UE paresis poststroke were enrolled. UE motor capacity was measured with the Action Research Arm Test (ARAT), and UE performance was measured using bilateral, wrist-worn accelerometers. Measurements were taken at or near the start of therapy, at every 10th visit or every 30 days throughout the duration of services, and at discharge. RESULTS. Three patterns were observed: (1) increase in ARAT scores and more normalized accelerometry profiles, (2) increase in ARAT scores but no change in accelerometry profiles, and (3) no change in ARAT scores or in accelerometry profiles. CONCLUSION. UE performance in daily life was highly variable, with inconsistencies between change in UE capacity and change in UE performance. UE capacity and performance are important constructs to assess separately during rehabilitation. PMID:27089298

    The authors report about an own case of recurrent sporadic hypertrophic polyneuropathy and describe the clinical course and histologic picture with reference to the literature. The disease is characterized by recurrences of subacutely occurring polyradiculoneuropathy and sequent nearly complete remission. Clinical examination discloses preferentially symmetrically and distally occurring motor paresis while sensibility in most cases is less affected. The peripheral nerves may be enlarged after a few relapses and frequently painful to pressure during the bout. Excessive increase in CSF proteins is found only during the bout. Motor nerve conduction velocity is considerably reduced. Histological pictures typically present an onion bulb formation of the Schwann cells with marked proliferation of connective tissue. There frequently younger individuals are involved; the relation female to male is 3:1. Differentiation has to be made concerning hereditary and symptomatic forms of hypertrophic polyneuropathy.

    Acute intermittent porphyria (AIP), the most common and the most severe form of acute hepatic porphyria, is an autosomal dominant condition. It results from lower-than-normal levels (less than 50%) of porphobilinogen (PBG) deaminase. Patients may present commonly with gastrointestinal complaints and neuropsychiatric manifestations. Diagnosis may be confirmed with the presence of intermediary metabolites of haem synthesis, amino levulinic acid (ALA) and PBG in urine or with specific enzyme assays. Abdominal pain is the most common symptom (90%). Peripheral polyneuropathy, primarily motor with flaccid paresis of proximal musculature, with or without autonomic involvement, is characteristic. Respiratory failure necessitates ventilator and intensive care support. Avoidance of precipitating factors and the use of haem preparations and intravenous dextrose form the basis of management. Gabapentin and propofol, rather than the conventional antiepileptics appear to be the appropriate choice for seizure control. Here, we present intensive care management of four cases of AIP with varying clinical presentation. PMID:20859493

    Hypothalamic hamartomas (HH) are congenital malformations of the hypothalamus, often generating medically refractory gelastic seizures. There is great risk of progression to various complex partial and generalized seizures and of cognitive and behavioral deterioration. Hence, various surgical approaches have been introduced to resect or disconnect the HH from surrounding tissue, and stereoendoscopic disconnection has been advocated as one of the most lenient approaches to sessile HH embedded in the third ventricle. In fact, no long-term neurological or cognitive impairments have hitherto been reported after this procedure. Yet, unforeseen complications may arise in any surgical intervention on this region. We found serious deterioration of memory and reading skills by comprehensive neuropsychological assessments pre- and postoperatively in a child who, before surgery, was age-appropriate with respect to cognitive, emotional, and behavioral development. The child also contracted a permanent oculomotor paresis. Our results are discussed in light of previous relevant findings. PMID:22546525

    From January to June 1994, we operated conventionally on 121 consecutive hemiated lumbar disc patients as part of a prospective study. We analysed general data, case histories, neurological findings on admission and all data from imaging investigations and therapy. In addition, all patients received a questionnaire based on the Low Back Outcome Score. Most of the patients (93%) were followed-up for 1 year postoperatively in the same manner. On the Prolo Scale, we obtained a good result in 70%; 76% had a good Low Back Outcome Score. Predictive factors are different for different outcome scales. The preoperative duration of pain, the preoperative duration of paresis and smoking seem to be general predictive factors. PMID:9258635

    Vascular myelopathies of the spinal cord have not been described in Suidae, and are a rare finding in companion animals. An 8.5-yr female African warthog (Phacochoerus africanus) presented with an acute onset of tetraparesis. Based on neurologic findings, a cervical spinal cord lesion between C7-T2 was suspected. Magnetic resonance imaging revealed severe intramedullary hemorrhage with suspected abnormal vessels in the spinal cord at the level of the seventh cervical vertebrae. The acute onset of clinical signs and rapid deterioration of neurological status precluded surgical managements. A vascular anomaly was suspected on gross pathology and histology. Immunohistochemistry identified the lesion as a spontaneous intramedullary hematoma. Spontaneous intramedullary hematomyelia should be considered as a differential for acute onset of paresis in suid species. PMID:17319141

    An adult male Italian wolf (Canis lupus italicus) was presented with an abnormal gait. Neurologic examination showed thoracic kyphosis, paraparesis, decreased proprioception in the pelvic limbs, and normal spinal reflexes. Neurologic symptoms suggested a thoracolumbar spinal cord lesion. Pathologic findings included leukocytosis. Spinal radiographs revealed ventral spondylosis of T4/T5/T6, a poorly defined intervertebral disc space, and mild lysis of the vertebral margins. Multiple metallic foreign bodies were seen in the thoracic wall. Magnetic resonance imaging of the spine detected increased signal intensity on fluid sensitive sequences of the vertebral bodies, the intervertebral disc, and surrounding soft tissues. These findings were interpreted as active discospondylitis at T4/T5. Medical therapy included antibiotic and analgesic treatment as well as movement restriction. Follow-up at 4 wk showed significant clinical and radiologic improvement. Discospondylitis should be included in the differential diagnosis in wolves with paresis. PMID:24450075

    Degenerative processes in a movement segment of the vertebral column, which can potentially give rise to herniation of elements of the nucleus pulposus, are complex and of variable clinical and radiological dimensions; however the mere assumption that degenerative changes precede disc herniation remains a matter of debate. By definition, spinal disc herniation (SDH) refers to components of the gelatinous nucleus pulposus protruding beyond the dorsal level of the vertebral body margin through tears in the annulus fibrosus. Clinical presentation may include pain, paresis and sensory disturbances. Magnetic resonance imaging (MRI) is considered the gold standard in the diagnosis of SDH. In the majority of patients a conservative approach with physical therapy exercises and adequate analgesic and antiphlogistic medical treatment results in a substantial improvement of symptoms.

    Lumbar disc herniation has a high prevalence and strong social-medical impact. Patients suffer from lower back pain that radiates from the spine. Loss of sensation or paresis adds to the clinical picture. The diagnosis should be confirmed by imaging in patients considered for surgery. High remission rates initially warrant conservative treatment (adequate analgesia and physiotherapy) in many patients. If this treatment does not lead to significant alleviation within 5-8 weeks, surgery should be performed to reduce the risk of chronic nerve affection. Posterior interlaminar fenestration is the intervention primarily conducted for this diagnosis. A relapse in the same region occurs in up to 10% of patients after months through years, which sometimes necessitates a reoperation if symptoms are pertinent. PMID:22124958

    The most common cause of stridor in newborns is instability of the upper larynx, called laryngomalacia. In approximately 10% of children normal development is impaired. The diagnostics and therapy must follow a clear plan that is also comprehensible to the parents. The obstruction should be localized endoscopically, the anatomical characteristics determined, and the surgical possibilities evaluated. Additional pathological changes of the upper airway (e.g., vocal fold paresis) need to be excluded. Surgery for laryngomalacia, called supraglottoplasty, allows reduction of excess mucus, transectioning of aryepiglottic folds that are too short, and in some cases epiglottic fixation to the base of the tongue. In extreme cases tracheotomy is unavoidable. Surgery is only recommended for severe cases; when carried out correctly according to the medical indications, the success rate is over 90%.

    Myelinated fibers are organized into distinct domains that are necessary for saltatory conduction. These domains include the nodes of Ranvier and the flanking paranodal regions where glial cells closely appose and form specialized septate-like junctions with axons. These junctions contain a Drosophila Neurexin IV-related protein, Caspr/Paranodin (NCP1). Mice that lack NCP1 exhibit tremor, ataxia, and significant motor paresis. In the absence of NCP1, normal paranodal junctions fail to form, and the organization of the paranodal loops is disrupted. Contactin is undetectable in the paranodes, and K(+) channels are displaced from the juxtaparanodal into the paranodal domains. Loss of NCP1 also results in a severe decrease in peripheral nerve conduction velocity. These results show a critical role for NCP1 in the delineation of specific axonal domains and the axon-glia interactions required for normal saltatory conduction. PMID:11395000

    Atherosclerosis is a common disease in parrots. The disease is found in all common parrot species, but especially in African Grey parrots and Amazons. It is a disease of older birds that is seen in both males and females. The most common sign is sudden death, but clinical symptoms that can be found include dyspnea, lethargy and nervous signs, such as paresis and collapses. Because the clinical signs are seldomly seen, it is difficult to diagnose atherosclerosis and therefore it is mostly an unexpected finding at necropsy. Age and species are determinants of atherosclerosis in parrots. Suggested risk factors include an elevated plasma cholesterol level, diet composition, social stress and inactivity, but research is needed to confirm this. PMID:15230050

    A 78-year-old man presented to hospital with new onset confusion and fever. The working diagnosis was of delirium due to an infection of unknown source, and empirical i.v. antibiotic treatment was given. Two days later, he deteriorated and developed clinical features in keeping with a total anterior circulation stroke. Brain imaging was unremarkable. Blood cultures grew an organism subsequently identified as Facklamia languida. Following treatment with broad-spectrum antibiotics, his condition improved. A diagnosis of F. languida septicaemia, leading to presumed (unwitnessed) seizure and Todd's paresis was made. The patient went on to make a full recovery and was discharged home. Stroke mimics are common and may be eminently treatable. Around a quarter of patients initially suspected to have a stroke are subsequently found to have an alternative diagnosis. PMID:25038834

    A twelve-year-old African-American female presented with two week history of progressively worsening headache and fatigue, and vision difficulties for the past week. The physical examination was normal. The neurological evaluation was normal, except for cranial nerves (CN) testing, which showed bilateral restriction of adduction (CN III) and up gaze (CN IV) motions, vertical nystagmus, and left side facial paresis of central origin (CN VII). The bilateral exotropia and ophthalmoplegia are characteristics of WEBINO (Wall-Eyed Bilateral Intranuclear Ophthalmoplegia) syndrome, associated to a brain stem structural lesion. The following causes were evaluated and ruled out: tumor, infection, ischemic stroke, non-infectious inflammation. Pediatric Acquired Demyelinating Syndromes were then considered. Neuromyelitis Optica was ruled out in the absence of neuritis and normal spinal cord MRI. The differential diagnosis between Clinically Isolated Syndrome and Acute Demyelinating Encephalomyelitis, causing an isolated brain stem syndrome, is discussed. PMID:25149958

    Background Context. Up to date, only four cases of primary intradural extramedullary spinal cord melanoma (PIEM) have been reported. No previous reports have described a case of PIEM located in the lower thoracic spine with long-term follow-up. Purpose. Demonstrating an unusual, extremely rare case of melanoma manifestation. Study Design. Case report. Methods. We report a case of a 57-year-old female suffering from increasing lower extremity pain, left-sided paresis, and paraesthesia due to spinal cord compression caused by PIEM in the lower thoracic spine. Results. Extensive investigation excluded other possible primary melanoma sites and metastases. For spinal cord decompression, the tumor at level T12 was resected, yet incompletely. Adjuvant radiotherapy was administered two weeks after surgery. The patient was recurrence-free at 104 weeks after radiotherapy but presents with unchanged neurological symptoms. Conclusion. Primary intradural extramedullary melanoma (PIEM) is extremely rare and its clinical course is unpredictable. PMID:27127667

    We report a 21-year-old patient who presented at the outpatient department of angiology with incipient necroses in the fingertips of the right hand. Colour-coded duplex sonography and angiography demonstrated occlusion of the right brachial, ulnar and radial arteries, obviously resulting from an embolism from the subclavian artery narrowed by a cervical rib. After partly successful local thrombolysis this accessory rib was resected. We review angiologic signs and neurological symptoms of the thoracic outlet syndrome (TOS) and analyse the current literature regarding diagnostic procedures and treatment. This complicated and severe case of TOS in a young patient ending with paresis of the right arm and partial finger amputation emphasises the importance of early diagnosis of this condition.

    Patients with temporomandibular muscle and joint disorder (TMJD) increasingly seek and receive treatment for their pain with botulinum toxin (BoNTA; botulinum toxin A). Used intramuscularly in therapeutic doses, it produces localised paresis. Such paresis creates risk of reduced bone mineral density, or 'disuse osteopenia'. Animal studies have frequently used BoNTA as a model of paralysis to induce bone changes within short periods. Osteopenic effects can be enduring in animals but have yet to be studied in humans. This is the first study in humans to examine bone-related consequences of BoNTA injections in the masticatory muscles, comparing oral and maxillofacial radiologists' ratings of trabecular bone patterns in the condyles of patients with TMJD exposed to multiple masticatory muscle injection sessions with BoNTA to a sample of patients with TMJD unexposed to masticatory muscle injections with BoNTA. Cone-beam computed tomography (CBCT)-derived images of bilateral condyles were evaluated in seven patients with TMJD receiving 2+ recent BoNTA treatment sessions for facial pain and nine demographically matched patients with TMJD not receiving BoNTA treatment. Two oral and maxillofacial radiologists evaluated CBCT images for evidence of trabecular changes consistent with osteopenia. Both evaluators noted decreased density in all participants exposed to BoNTA and in none of the unexposed participants (P < 0.001). No other abnormalities associated with reduced loading were detected. These findings need replication in a larger sample and over a longer time period, to ensure safety of patients with TMJD receiving multiple BoNTA injections for their pain. PMID:24836732

    The gathering of visual information is a complex process that relies on concerted movements of the eyes, and cranial nerves II-VIII are at least partially involved in the visual system. The cranial nerves do not function in isolation, however, and there are multiple higher-order cortical centers that have input into the cranial nerves to coordinate eye movement. Among the functions of the cortical reflex pathways are (a) controlling vertical and horizontal gaze in response to vestibular input to keep the eyes focused on an object as the head moves through space, and (b) controlling rapid, coordinated eye movement to a new visual target (saccades). There are also reflex pathways connecting the cranial nerves involved in vision that produce consensual blinking of the eyes in response to corneal stimulation of one eye and consensual pupillary constriction in response to light input on one pupil. A variety of intracranial pathologic conditions, including benign and malignant neoplasms, infection, trauma, autoimmune diseases, vascular anomalies, degenerative diseases, and inherited-congenital disorders, can disrupt the cranial nerves and visual reflex pathways. This disruption can manifest in myriad ways-for example, as extraocular muscle paresis, afferent pupillary defect, oculosympathetic paresis (Horner syndrome), internuclear ophthalmoplegia, dorsal midbrain (Parinaud) syndrome, or loss of the corneal reflex. Knowledge of the function and anatomy of the cranial nerves and visual reflex pathways, coupled with selection of the proper magnetic resonance pulse sequence, will allow the radiologist to order appropriate imaging of the involved cranial nerve or visual reflex pathway based on the patient's symptoms and thereby play an essential role in establishing the diagnosis and planning appropriate therapy.

    Aspergillosis is a common respiratory fungal disease in penguins managed under human care. Triazole antifungal drugs, including itraconazole, are most commonly used for treatment; however, itraconazole treatment failures from drug resistance are becoming more common, requiring newer treatment options. Voriconazole, a newer triazole, is being used more often. Until recently, no voriconazole pharmacokinetic studies had been performed in penguins, leading to empiric dosing based on other avian studies. This has led to increased anecdotal reporting of apparent voriconazole toxicity in penguins. This report describes 18 probable and 6 suspected cases of voriconazole toxicity in six penguin species from nine institutions: 12 African penguins (Spheniscus demersus), 5 Humboldt penguins (Spheniscus humboldti), 3 Magellanic penguins (Spheniscus magellanicus), 2 gentoo penguins (Pygoscelis papua papua), 1 macaroni penguin (Eudyptes chrysolophus), and 1 emperor penguin (Aptenodytes forsteri). Observed clinical signs of toxicity included anorexia, lethargy, weakness, ataxia, paresis, apparent vision changes, seizure-like activity, and generalized seizures. Similar signs of toxicity have also been reported in humans, in whom voriconazole therapeutic plasma concentration for Aspergillus spp. infections is 2-6 μg/ml. Plasma voriconazole concentrations were measured in 18 samples from penguins showing clinical signs suggestive of voriconazole toxicity. The concentrations ranged from 8.12 to 64.17 μg/ml, with penguins having plasma concentrations above 30 μg/ml exhibiting moderate to severe neurologic signs, including ataxia, paresis, and seizures. These concentrations were well above those known to result in central nervous system toxicity, including encephalopathy, in humans. This case series highlights the importance of species-specific dosing of voriconazole in penguins and plasma therapeutic drug monitoring. Further investigation, including pharmacokinetic studies, is

    Two 15-yr-old grizzly bear littermates were evaluated within 9 mo of each other with the symptom of acute onset of progressive paraparesis and proprioceptive ataxia. The most significant clinical examination finding was pelvic limb paresis in both bears. Magnetic resonance examinations of both bears showed cranial thoracic spinal cord compression. The first bear had left-sided extradural, dorsolateral spinal cord compression at T3-T4. Vertebral canal stenosis was also observed at T2-T3. Images of the second bear showed lateral spinal cord compression from T2-T3 to T4-T5. Intervertebral disk disease and associated spinal cord compression was also observed at T2-T3 and T3-T4. One grizzly bear continued to deteriorate despite reduced exercise, steroid, and antibiotic therapy. The bear was euthanized, and a necropsy was performed. The postmortem showed a spinal ganglion cyst that caused spinal cord compression at the level of T3-T4. Wallerian-like degeneration was observed from C3-T6. The second bear was prescribed treatment that consisted of a combination of reduced exercise and steroid therapy. He continued to deteriorate with these medical therapies and was euthanized 4 mo after diagnosis. A necropsy showed hypertrophy and protrusion of the dorsal longitudinal ligament at T2-T3 and T3-T4, with resulting spinal cord compression in this region. Wallerian-like degeneration was observed from C2-L1. This is one of few case reports that describes paresis in bears. It is the only case report, to the authors' knowledge, that describes spinal magnetic resonance imaging findings in a grizzly bear and also the only report that describes a cranial thoracic myelopathy in two related grizzly bears with neurologic signs.

    Fifteen cows with milk fever were treated with 500ml of 40 % calcium borogluconate (group A) administered intravenously. Fifteen other cows with milk fever received the same treatment, supplemented with 500ml of 10 % sodium phosphate administered intravenously, and 80g calcium as calcium lactate and 70g inorganic phosphorus as sodium phosphate administered orally in drinking water. The cows were monitored and blood samples collected for 3 days to measure the concentrations of total and ionized calcium, inorganic phosphorus and magnesium and the activity of creatine kinase. The two groups did not differ significantly with respect to the course of the disease. In each group 14 cows were cured. A rapid and significant increase in serum calcium concentration from the hypo- to the hypercalcaemic range occurred in both groups within 10min of the start of treatment, followed by a slow and steady decrease to the hypocalcaemic range. Calcium lactate did not prevent the calcium concentration from returning to the hypocalcaemic range, and the calcium profiles of the two groups did not differ significantly. As expected, treatment had little effect on the concentration of inorganic phosphorus in group A. In group B, treatment caused a rapid increase in the concentration of inorganic phosphorus to a maximum 20min after the start of treatment. This was followed by a slow decrease in the phosphorus concentration to the normophosphataemic range. Our findings confirmed that combined intravenous and oral administration of sodium phosphate in cows with periparturient paresis attributable to hypocalcaemia and hypophosphataemia results in a rapid and sustained increase in serum phosphorus, but not in serum calcium concentration. This modified therapy did not improve the success rate of milk fever treatment and further studies are needed to improve treatment of periparturient paresis. PMID:22923322

    Background Paresis in stroke is largely a result of damage to descending corticospinal and corticobulbar pathways. Recovery of paresis predominantly reflects the impact on the neural consequences of this white matter lesion by reactive neuroplasticity (mechanisms involved in spontaneous recovery) and experience-dependent neuroplasticity, driven by therapy and daily experience. However, both theoretical considerations and empirical data suggest that type of stroke (large vessel distribution/lacunar infarction, hemorrhage), locus and extent of infarction (basal ganglia, right-hemisphere cerebral cortex), and the presence of leukoaraiosis or prior stroke might influence long-term recovery of walking ability. In this secondary analysis based on the 408 participants in the Locomotor Experience Applied Post-Stroke (LEAPS) study database, we seek to address these possibilities. Methods Lesion type, locus, and extent were characterized by the 2 neurologists in the LEAPS trial on the basis of clinical computed tomography and magnetic resonance imaging scans. A series of regression models was used to test our hypotheses regarding the effects of lesion type, locus, extent, and laterality on 2- to 12-month change in gait speed, controlling for baseline gait speed, age, and Berg Balance Scale score. Results Gait speed change at 1 year was significantly reduced in participants with basal ganglia involvement and prior stroke. There was a trend toward reduction of gait speed change in participants with lacunar infarctions. The presence of right-hemisphere cortical involvement had no significant impact on outcome. Conclusions Type, locus, and extent of lesion, and the loss of substrate for neuroplastic effect as a result of prior stroke may affect long-term outcome of rehabilitation of hemiparetic gait.

    OBJECTIVE The authors' aim in this paper is to prove the feasibility of resting-state (RS) functional MRI (fMRI) in an intraoperative setting (iRS-fMRI) and to correlate findings with the clinical condition of patients pre- and postoperatively. METHODS Twelve patients underwent intraoperative MRI-guided resection of lesions in or directly adjacent to the central region and/or pyramidal tract. Intraoperative RS (iRS)-fMRI was performed pre- and intraoperatively and was correlated with patients' postoperative clinical condition, as well as with intraoperative monitoring results. Independent component analysis (ICA) was used to postprocess the RS-fMRI data concerning the sensorimotor networks, and the mean z-scores were statistically analyzed. RESULTS iRS-fMRI in anesthetized patients proved to be feasible and analysis revealed no significant differences in preoperative z-scores between the sensorimotor areas ipsi- and contralateral to the tumor. A significant decrease in z-score (p < 0.01) was seen in patients with new neurological deficits postoperatively. The intraoperative z-score in the hemisphere ipsilateral to the tumor had a significant negative correlation with the degree of paresis immediately after the operation (r = -0.67, p < 0.001) and on the day of discharge from the hospital (r = -0.65, p < 0.001). Receiver operating characteristic curve analysis demonstrated moderate prognostic value of the intraoperative z-score (area under the curve 0.84) for the paresis score at patient discharge. CONCLUSIONS The use of iRS-fMRI with ICA-based postprocessing and functional activity mapping is feasible and the results may correlate with clinical parameters, demonstrating a significant negative correlation between the intensity of the iRS-fMRI signal and the postoperative neurological changes.

    Recovery of upper limb movement control after stroke might be enhanced by repetitive goal-directed functional activities. Providing such activity is challenging in the presence of severe paresis. A possible new approach is based on the discovery of mirror neurons in the monkey cortical area F5, which are active both in observing and executing a movement. Indirect evidence for a comparable human "mirror neurone system" is provided by functional imaging. The primary motor cortex, the premotor cortex, other brain areas, and muscles appropriate for the action being observed are probably activated in healthy volunteers observing another's movement. These findings raise the hypothesis that observation of another's movement might train the movement execution system of stroke patients who have severe paresis to bring them to the point at which they could actively participate in rehabilitation consisting of goal-directed activities. The point of providing an observation therapy would be to facilitate the voluntary production of movement; therefore, the condition of interest would be observation with intent to imitate. However, there is as yet insufficient evidence to enable the testing of this hypothesis in stroke patients. Studies in normal subjects are needed to determine which brain sites are activated in response to observation with intent to imitate. Studies in stroke subjects are needed to determine how activation is affected after damage to different brain areas. The information from such studies should aid identification of those stroke patients who might be most likely to benefit from observation to imitate and therefore guide phase I clinical studies.

  16. Parsonage-Turner syndrome following post-exposure prophylaxis

    PubMed Central

    2014-01-01

    Background The ‘Parsonage-Turner syndrome’ (PTS) is a rare but distinct disorder with an abrupt onset of shoulder pain, followed by weakness and atrophy of the upper extremity musculature, and a slow recovery requiring months to years. To our best knowledge, this is the first case describing symptoms and signs of PTS following the administration of a post-exposure prophylaxis (PEP) regimen against possible human immunodeficiency virus (HIV) and hepatitis B virus (HBV) infection. Case presentation A 25-year-old Caucasian man presented with pain and unilateral scapular winging following PEP against possible HIV and HBV infection. Although atrophy and weakness were observed for the right supraspinatus muscle, a full range of motion was achievable. Neurological examination, plain radiography of the right shoulder and electromyography showed no additional abnormalities. The patient was diagnosed with post-vaccination PTS and treated non-operatively. During the following 15 months the scapular winging receded and full muscle strength was regained. Conclusion Parsonage-Turner syndrome is a rare clinical diagnosis. The precise pathophysiological mechanism of PTS remains unclear, but it seems to involve an interaction between genetic predisposition, mechanical vulnerability and an autoimmune trigger. An immunological event, such as – in this case – a vaccination as part of PEP treatment, can trigger the onset of PTS. The clinical presentation is distinctive with acute severe pain followed by patchy paresis, atrophy and sensory symptoms that persist for months to years. No currently available tests can provide a definite confirmation or exclusion of PTS. Routine blood examination, electromyography (EMG), and computed tomography (CT) or magnetic resonance imaging (MRI) serve mainly to exclude other disorders. The recovery can be quite lengthy, non-operative treatment is the accepted practice. Supplementary administration of oral prednisolone could shorten the

    Stroke is one of the major causes of death and disability in America. After stroke, about 65% of survivors still suffer from severe paresis, while rehabilitation treatment strategy after stroke plays an essential role in recovery. Currently, there is a clinical trial (NIH award #HD065438) to determine the optimal dose of rehabilitation for persistent recovery of arm and hand paresis. For DOSE (Dose Optimization Stroke Evaluation), laboratory-based measurements, such as the Wolf Motor Function test, behavioral questionnaires (e.g. Motor Activity Log-MAL), and MR, DTI, and Transcranial Magnetic Stimulation (TMS) imaging studies are planned. Current data collection processes are tedious and reside in various standalone systems including hardcopy forms. In order to improve the efficiency of this clinical trial and facilitate decision support, a web-based imaging informatics system has been implemented together with utilizing mobile devices (eg, iPAD, tablet PC's, laptops) for collecting input data and integrating all multi-media data into a single system. The system aims to provide clinical imaging informatics management and a platform to develop tools to predict the treatment effect based on the imaging studies and the treatment dosage with mathematical models. Since there is a large amount of information to be recorded within the DOSE project, the system provides clinical data entry through mobile device applications thus allowing users to collect data at the point of patient interaction without typing into a desktop computer, which is inconvenient. Imaging analysis tools will also be developed for structural MRI, DTI, and TMS imaging studies that will be integrated within the system and correlated with the clinical and behavioral data. This system provides a research platform for future development of mathematical models to evaluate the differences between prediction and reality and thus improve and refine the models rapidly and efficiently.

    Radiation injury to peripheral nerve is a dose-limiting toxicity in the clinical application of intraoperative radiotherapy, particularly for pelvic and retroperitoneal tumors. Intraoperative radiotherapy-related peripheral neuropathy in humans receiving doses of 20-25 Gy is manifested as a mixed motor-sensory deficit beginning 6-9 months following treatment. In a previous experimental study of intraoperative radiotherapy-related neuropathy of the lumbro-sacral plexus, an approximate inverse linear relationship was reported between the intraoperative dose (20-75 Gy range) and the time to onset of hind limb paresis (1-12 mos following intraoperative radiotherapy). The principal histological lesion in irradiated nerve was loss of large nerve fibers and perineural fibrosis without significant vascular injury. Similar histological changes in irradiated nerves were found in humans. To assess peripheral nerve injury to lower doses of intraoperative radiotherapy in this same large animal model, groups of four adult American Foxhounds received doses of 10, 15, or 20 Gy to the right lumbro-sacral plexus and sciatic nerve using 9 MeV electrons. The left lumbro-sacral plexus and sciatic nerve were excluded from the intraoperative field to allow each animal to serve as its own control. Following treatment, a complete neurological exam, electromyogram, and nerve conduction studies were performed monthly for 1 year. Monthly neurological exams were performed in years 2 and 3 whereas electromyogram and nerve conduction studies were performed every 3 months during this follow-up period. With follow-up of greater than or equal to 42 months, no dog receiving 10 or 15 Gy IORT shows any clinical or laboratory evidence of peripheral nerve injury. However, all four dogs receiving 20 Gy developed right hind limb paresis at 8, 9, 9, and 12 mos following intraoperative radiotherapy.

    Objectives Pure tone audiometry and caloric test in patients with herpes zoster oticus were performed to determine the biologic features of the varicella zoster virus (VZV) and the pathogenesis of vestibulocochlear nerve disease in herpes zoster oticus. Study Design A retrospective chart review of 160 patients with herpes zoster oticus was designed in order to determine the classic characteristics of vestibulocochlear nerve disease associated with the syndrome. Speech frequency and isolated high frequency acoustic thresholds were analyzed based on severity of facial paralysis and patient age. Patients without cochlear symptoms were selected randomly, and audiological function was evaluated. Patients with symptoms of vestibular dysfunction underwent the caloric test, and canal paresis was analyzed according to the severity of facial paralysis and the age of each patient. Results Among the 160 patients, 111 exhibited pure tone audiometry; 26 (79%) of the patients with cochlear symptoms and 44 (56%) of the patients without cochlear symptoms had abnormal audiological data. Among the patients without cochlear symptoms, 15 (19%) had hearing loss at speech frequency, and 42 (54%) had hearing loss isolated to high frequency. The incidence of cochlear symptoms in herpes zoster oticus was not related to the severity of facial paralysis. The incidence of patients with isolated high frequency hearing loss statistically increased with age, however the incidence of patients with speech frequency hearing loss did not increase. Thirteen patients complained vertigo, and the incidence of vestibular disturbances and the value of canal paresis in the caloric test increased to statistical significance in parallel with increasing severity of facial paralysis. Conclusion Mild or moderate cochlear symptoms with high frequency hearing loss were related to age, and severe vestibular symptoms were related to the severity of facial paralysis after onset of herpetic symptoms.

    Acute unilateral vestibulopathy (AUV) is characterized by acute vertigo, nausea, and imbalance without neurological deficits or auditory symptomatology. Here, we explore the effect of glucocorticoid treatment on the degree of canal paresis in patients with AUV, and critically, establish its relationship with dizziness symptom recovery. We recruited consecutive patients who were retrospectively assigned to one of the two groups according to whether they received glucocorticoid treatment (n = 32) or not (n = 44). All patients underwent pure-tone audiometry, bithermal caloric testing, MRI brain imaging, and were asked to complete a dizziness handicap inventory on admission to hospital and just prior to hospital discharge. In the treatment group, the canal paresis at discharge was significantly lower than in the control group (mean ± SD % 38.04 ± 21.57 versus 82.79 ± 21.51, p < 0.001). We also observed a significant reduction in the intensity of nystagmus in patients receiving glucocorticoid treatment compared to the non-treatment group (p = 0.03). DHI test score was significantly lower at discharge in the treatment group (mean ± SD % 23.15 ± 12.40 versus 64.07 ± 12.87, p < 0.001), as was the length of hospital stay (2.18 ± 1.5 days versus 3.6 ± 1.7 days, p = 0.002). Glucocorticoid treatment leads to acute symptomatic improvement, with a reduced hospital stay and reduction in the intensity of acute nystagmus. Our findings suggest that glucocorticoids may accelerate vestibular compensation via a restoration of peripheral vestibular function, and therefore has important clinical implications for the treatment of AUV.

    Calculated globulin (total protein – albumin) is usually tested as part of a liver function test profile in both primary and secondary care and determines the serum globulin concentration, of which immunoglobulins are a major component. The main use hitherto of calculated globulin is to detect paraproteins when the level is high. This study investigated the potential to use low levels of calculated globulin to detect antibody deficiency. Serum samples with calculated globulin cut-off < 18 g/l based on results of a pilot study were collected from nine hospitals in Wales over a 12-month period. Anonymized request information was obtained and the samples tested for immunoglobulin levels, serum electrophoresis and, if appropriate, immunofixation. A method comparison for albumin measurement using bromocresol green and bromocresol purple was undertaken. Eighty-nine per cent (737 of 826) samples had an immunoglobulin (Ig)G level of < 6 g/l using the bromocresol green methodology with a cut-off of < 18 g/l, and 56% (459) had an IgG of < 4 g/l. Patients with both secondary and primary antibody deficiency were discovered and serum electrophoresis and immunofixation showed that 1·2% (10) had previously undetected small paraproteins associated with immune-paresis. Using bromocresol purple, 74% of samples had an IgG of < 6 g/l using a cut-off of < 23 g/l. Screening using calculated globulin with defined cut-off values detects both primary and secondary antibody deficiency and new paraproteins associated with immune-paresis. It is cheap, widely available and under-utilized. Antibody-deficient patients have been discovered using information from calculated globulin values, shortening diagnostic delay and time to treatment with immunoglobulin replacement therapy.

    Grass hay produced in the Coeur d'Alene River Basin of northern Idaho was fed to a group of 4 ponies. The hay contained Pb in concentration of 423 +/- 82 mg/kg and Cd in concentration of 10.8 +/- 1.4 mg/kg, resulting in daily exposures of the ponies to approximately 7.4 mg of Pb/kg and 0.19 mg of Cd/kg/day. The results in this group of ponies were compared with those from a group fed noncontaminated grass hay and given a daily dose of 10 mg of Pb/kg of body weight, in the form of lead acetate. Clinical toxicologic signs, hematologic changes, and blood and tissue Pb concentrations were similar in the 2 groups. However, the severity of the disease process appeared to be greater in the ponies fed the Pb- and Cd-contaminated hay. This was shown clearly by the shorter interval between onset of clinical changes and death in the ponies fed contaminated hay. The possibility of multiple heavy metal effects is discussed. Clinical toxicologic signs observed include incoordination, labial paresis, pharyngeal paresis, CNS depression, anorexia, and body weight loss. Anemia or marginal anemia was common and was often accompanied by the appearance of nucleated RBC and Howell-Jolly bodies in peripheral blood. Neither the hematologic response nor the blood Pb concentrations were reflective of the severity of poisoning, although blood Pb concentrations were greater than 0.35 micrograms/ml once clinical signs of toxicity were observed. Liver, kidney, spleen, brain, and bone Pb concentrations and liver, kidney, and brain Cd concentrations were increased in both the ponies fed contaminated hay and the ponies given lead acetate.

    Background Athetosis has been controversial since it was first described by William Hammond in 1871; many aspects of Hammond’s career were equally controversial. Methods Primary sources have been used to review treatment controversies in the 50-year period following the initial description of athetosis. Results The treatments used most commonly employed available pharmaceutical agents and modalities (e.g., galvanism). Initial anecdotal reports of success were seldom confirmed with subsequent experience. Several novel invasive therapies were also developed and promoted, all of which damaged or destroyed either upper or lower motor neuron pathways, and were also often associated with high mortality rates. In general, these therapies substituted paresis for abnormal spontaneous movements. These included peripheral nerve stretching, excision of a portion of the precentral gyrus, rhizotomy, nerve “transplantation” (i.e., neurotomy and nerve-to-nerve anastomoses), and “muscle group isolation” (i.e., alcohol neurolysis). There was no agreement on the appropriateness of such high-risk procedures, particularly given the intentional generation of further neurological morbidity. Discussion Pharmaceutical agents and modalities initially employed for athetosis had little a priori evidence-based justification and no biologically plausible theoretical framework to guide empiric treatment selection. Subsequently, all the invasive procedures employed were directed at lessening or removing the manifestations, rather than the underlying cause, of the abnormal central nervous system “irritation,” usually by imposing paresis or paralysis. Factors contributing to the disparity in outcomes between favorable initial reports and the often-disappointing results of later studies included reliance on anecdotal reports or small uncontrolled case series, placebo effects, biased observation, misdiagnosis, and biased reporting.

    Severe upper limb paresis is a major contributor to disability after stroke. This study investigated the efficacy of task-related training (TRT) with transcutaneous electrical nerve stimulation (TENS) on recovery of upper limb motor function in chronic-stroke survivors. Thirty patients with chronic stroke were randomly allocated two groups: the TRT+TENS group (n = 15) and the TRT+placebo (TRT+PLBO) group (n = 15). Patients in the TRT+TENS group received TENS stimulation (two to three times the sensory threshold), while subjects in the TRT+PLBO group received TENS without real electrical stimulation. TENS was applied to muscle belly of triceps and wrist extensors, while placebo (PLBO) stimulation was administrated without real electrical stimulation. Both interventions were given for 30 minutes per day, 5 days per week, for a period of 4 weeks. The primary outcomes were assessed with Fugl-Meyer assessment scores (FMA), Manual function test (MFT), Box and block test (BBT), and Modified Ashworth scale (MAS), each of which was performed one day before and one day after intervention. Both groups showed significant improvements in FMA, MFT, and BBT after intervention. When compared with the TRT+PLBO group, the TRT+TENS group showed significantly greater improvements in FMA (p = 0.034), MFT (p = 0.037), and BBT (p = 0.042). In MAS score, significant improvement was observed only in the TRT+TENS group (p = 0.011). Our findings indicate that TRT with TENS can reduce motor impairment and improve motor activity in stroke survivors with chronic upper limb paresis, highlighting the benefits of somatosensory stimulation from TENS.

    Objectives: To adapt to Spanish the facial disability index (FDI) described by VanSwearingen and Brach in 1995 and to assess its reliability and validity in patients with facial nerve paresis after parotidectomy. Study Design: The present study was conducted in two different stages: a) cross-cultural adaptation of the questionnaire and b) cross-sectional study of a control group of 79 Spanish-speaking patients who suffered facial paresis after superficial parotidectomy with facial nerve preservation. The cross-cultural adaptation process comprised the following stages: (I) initial translation, (II) synthesis of the translated document, (III) retro-translation, (IV) review by a board of experts, (V) pilot study of the pre-final draft and (VI) analysis of the pilot study and final draft. Results: The reliability and internal consistency of every one of the rating scales included in the FDI (Cronbach’s alpha coefficient) was 0.83 for the complete scale and 0.77 and 0.82 for the physical and the social well-being subscales. The analysis of the factorial validity of the main components of the adapted FDI yielded similar results to the original questionnaire. Bivariate correlations between FDI and House-Brackmann scale were positive. The variance percentage was calculated for all FDI components. Conclusions: The FDI questionnaire is a specific instrument for assessing facial neuromuscular dysfunction which becomes a useful tool in order to determine quality of life in patients with facial nerve paralysis. Spanish adapted FDI is equivalent to the original questionnaire and shows similar reliability and validity. The proven reproducibi-lity, reliability and validity of this questionnaire make it a useful additional tool for evaluating the impact of facial nerve paralysis in Spanish-speaking patients.

    Decreased conducting processes leading usually to conduction block and increased weakness of limbs during cold (cold paresis) or warmth (heat paresis) have been reported in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). To explore the mechanisms of these symptoms, the effects of temperature (from 20°C to 42°C) on nodal action potentials and their current kinetics in previously simulated case of 70% CIDP are investigated, using our temperature dependent multi-layered model of the myelinated human motor nerve fiber. The results show that potential amplitudes have a bifid form at 20°C. As in the normal case, for the CIDP case, the nodal action potentials are determined mainly by the nodal sodium currents (I Na ) for the temperature range of 20-39°C, as the contribution of nodal fast and slow potassium currents (I Kf and I Ks ) to the total ionic current (Ii) is negligible. Also, the contribution of I Kf and I Ks to the membrane repolarization is enhanced at temperatures higher than 39°C. However, in the temperature range of 20-42°C, all potential parameters in the CIDP case, except for the conduction block during hyperthermia (≥ 40°C) which is again at 45°C, worsen: (i) conduction velocities and potential amplitudes are decreased; (ii) afterpotentials and threshold stimulus currents for the potential generation are increased; (iii) the current kinetics of action potentials is slowed and (iv) the conduction block during hypothermia (≤ 25°C) is at temperatures lower than 20°C. These potential parameters are more altered during hyperthermia and are most altered during hypothermia. The present results suggest that the conducting processes in patients with CIDP are in higher risk during hypothermia than hyperthermia. PMID:25597276

  7. The FIB-PPH trial: fibrinogen concentrate as initial treatment for postpartum haemorrhage: study protocol for a randomised controlled trial

    PubMed Central

    2012-01-01

    Background Postpartum haemorrhage (PPH) remains a leading cause of maternal mortality worldwide. In Denmark 2% of parturients receive blood transfusion. During the course of bleeding fibrinogen (coagulation factor I) may be depleted and fall to critically low levels, impairing haemostasis and thus worsening the ongoing bleeding. A plasma level of fibrinogen below 2 g/L in the early phase of postpartum haemorrhage is associated with subsequent development of severe haemorrhage. Use of fibrinogen concentrate allows high-dose substitution without the need for blood type crossmatch. So far no publications of randomised controlled trials involving acutely bleeding patients in the obstetrical setting have been published. This trial aims to investigate if early treatment with fibrinogen concentrate reduces the need for blood transfusion in women suffering severe PPH. Methods/Design In this randomised placebo-controlled double-blind multicentre trial, parturients with primary PPH are eligible following vaginal delivery in case of: manual removal of placenta (blood loss ≥ 500 ml) or manual exploration of the uterus after the birth of placenta (blood loss ≥ 1000 ml). Caesarean sections are also eligible in case of perioperative blood loss ≥ 1000 ml. The exclusion criteria are known inherited haemostatic deficiencies, prepartum treatment with antithrombotics, pre-pregnancy weight <45 kg or refusal to receive blood transfusion. Following informed consent, patients are randomly allocated to either early treatment with 2 g fibrinogen concentrate or 100 ml isotonic saline (placebo). Haemostatic monitoring with standard laboratory coagulation tests and thromboelastography (TEG, functional fibrinogen and Rapid TEG) is performed during the initial 24 hours. Primary outcome is the need for blood transfusion. To investigate a 33% reduction in the need for blood transfusion, a total of 245 patients will be included. Four university-affiliated public

    Childbirth ranks among the most intense experiences of acute pain. Neuraxial analgesia (i.e. epidural or combined spinal-epidural technique) is the most effective way to relieve that pain but it is contraindicated or impossible to perform for some parturients. We designed a survey of the current use of analgesic alternatives to epidural analgesia (EA) for labor pain, specifically the use of opioid patient-controlled intravenous analgesia (PCIA), in the French part of Belgium (Wallonia and Brussels). A questionnaire was mailed to the departmental chair of the hospitals with an obstetric unit, both in university and non-university centers (total of 53 centers). The questionnaire evaluated the availability of EA, the alternatives used when EA was contraindicated, the use of opioid-based PCIA for labor analgesia as well as opioid preference and doses, and finally the reasons for not using opioid PCIA. The response rate was 67.5% (36 centers). Among the responding hospitals, EA was available for 68% (range 25-85%) of labors and deliveries. When EA was not available or contraindicated, a parenteral opioid (piritramide, tramadol or pethidine) was proposed in 19% (7/36) of the centers, Entonox in 11% (4/36), a pudendal block by obstetricians in 28% (10/36) and non-pharmacologic alternatives (i.e. hypnosis, sophrology, baths and massages) in 19% (7/36). In 28% (10/36) of the centers however, no analgesic alternative was proposed. Opioid PCIA was employed in 36% (13/36) of the centers and for an additional 11% (4/36) only in case of intrauterine death. Remifentanil was the first choice (76.5% of the PCIA), followed by sufentanil (23.5%). Other opioids (piritramide, morphine, fentanyl) and ketamine were also administered by PCIA. Forty-five percents of the centers reported never using opioid PCIA by either lack of knowledge (7%), fear of maternal or fetal side effects (48%) and unability to provide a correct supervision of the parturient during PCIA use (48%), opposition from

    Background The determinants and barriers for delivery and uptake of IPTp vary with different regions in sub-Saharan Africa. This study evaluated the determinants of ANC clinic attendance and IPTp-SP uptake among parturient women from Mount Cameroon Area and hypothesized that time of first ANC clinic attendance could influence uptake of IPTp-SP/dosage and consequently malaria parasite infection status at delivery. Methods Two cross sectional surveys were carried out at the Government Medical Centre in the Mutengene Health Area, Mt Cameroon Area from March to October 2007 and June 2008 to April 2009. Consented parturient women were consecutively enrolled in both surveys. In 2007, socio-demographic data, ANC clinic attendance, gestational age, fever history and reported use/dosage of IPTp-SP were documented using a structured questionnaire. In the second survey only IPT-SP usage/dosage was recorded. Malaria parasitaemia at delivery was determined by blood smear microscopy and placental histology. Results and discussion In 2007, among the 287 women interviewed, 2.2%, 59.7%, and 38.1% enrolled in the first, second and third trimester respectively. About 90% of women received at least one dose SP but only 53% received the two doses in 2007 and by 2009 IPTp-two doses coverage increased to 64%. Early clinic attendance was associated (P = 0.016) with fever history while being unmarried (OR = 2.2; 95% CI: 1.3-3.8) was significantly associated with fewer clinic visits (<4visits). Women who received one SP dose (OR = 3.7; 95% CI: 2.0-6.8) were more likely not to have attended ≥ 4visits. A higher proportion (P < 0.001) of women with first visit during the third trimester received only one dose, meanwhile, those who had an early first ANC attendance were more likely (OR = 0.4; 95% CI = 0.2 - 0.7) to receive two or more doses. Microscopic parasitaemia at delivery was frequent (P = 0.007) among women who enrolled in the third trimester and had

    This review discusses the physiology and pharmacological treatment of vertigo and related disorders. Classes of medications useful in the treatment of vertigo include anticholinergics, antihistamines, benzodiazepines, calcium channel antagonists and dopamine receptor antagonists. These medications often have multiple actions. They may modify the intensity of symptoms (e.g. vestibular suppressants) or they may affect the underlying disease process (e.g. calcium channel antagonists in the case of vestibular migraine). Most of these agents, particularly those that are sedating, also have a potential to modulate the rate of compensation for vestibular damage. This consideration has become more relevant in recent years, as vestibular rehabilitation physical therapy is now often recommended in an attempt to promote compensation. Accordingly, therapy of vertigo is optimised when the prescriber has detailed knowledge of the pharmacology of medications being administered as well as the precise actions being sought. There are four broad causes of vertigo, for which specific regimens of drug therapy can be tailored. Otological vertigo includes disorders of the inner ear such as Ménière's disease, vestibular neuritis, benign paroxysmal positional vertigo (BPPV) and bilateral vestibular paresis. In both Ménière's disease and vestibular neuritis, vestibular suppressants such as anticholinergics and benzodiazepines are used. In Ménière's disease, salt restriction and diuretics are used in an attempt to prevent flare-ups. In vestibular neuritis, only brief use of vestibular suppressants is now recommended. Drug treatments are not presently recommended for BPPV and bilateral vestibular paresis, but physical therapy treatment can be very useful in both. Central vertigo includes entities such as vertigo associated with migraine and certain strokes. Prophylactic agents (L-channel calcium channel antagonists, tricyclic antidepressants, beta-blockers) are the mainstay of treatment

    Background Intrauterine infection may play a role in preterm delivery due to spontaneous preterm labor (PTL) and preterm prolonged rupture of membranes (PPROM). Because bacteria previously associated with preterm delivery are often difficult to culture, a molecular biology approach was used to identify bacterial DNA in placenta and fetal membranes. Methodology/Principal findings We used broad-range 16S rDNA PCR and species-specific, real-time assays to amplify bacterial DNA from fetal membranes and placenta. 74 women were recruited to the following groups: PPROM <32 weeks (n = 26; 11 caesarean); PTL with intact membranes <32 weeks (n = 19; all vaginal birth); indicated preterm delivery <32 weeks (n = 8; all caesarean); term (n = 21; 11 caesarean). 50% (5/10) of term vaginal deliveries were positive for bacterial DNA. However, little spread was observed through tissues and species diversity was restricted. Minimal bacteria were detected in term elective section or indicated preterm deliveries. Bacterial prevalence was significantly increased in samples from PTL with intact membranes [89% (17/19) versus 50% (5/10) in term vaginal delivery p = 0.03] and PPROM (CS) [55% (6/11) versus 0% (0/11) in term elective CS, p = 0.01]. In addition, bacterial spread and diversity was greater in the preterm groups with 68% (13/19) PTL group having 3 or more positive samples and over 60% (12/19) showing two or more bacterial species (versus 20% (2/10) in term vaginal deliveries). Blood monocytes from women with PTL with intact membranes and PPROM who were 16S bacterial positive showed greater level of immune paresis (p = 0.03). A positive PCR result was associated with histological chorioamnionitis in preterm deliveries. Conclusion/Significance Bacteria are found in both preterm and term fetal membranes. A greater spread and diversity of bacterial species were found in tissues of women who had very preterm births. It is unclear to what extent the greater

    Purpose: To measure the relative biological effectiveness (RBE) of carbon ions in the rat spinal cord as a function of linear energy transfer (LET). Methods and Materials: As an extension of a previous study, the cervical spinal cord of rats was irradiated with single doses of carbon ions at 6 positions of a 6-cm spread-out Bragg peak (16-99 keV/μm). The TD{sub 50} values (dose at 50% complication probability) were determined according to dose-response curves for the development of paresis grade 2 within an observation time of 300 days. The RBEs were calculated using TD{sub 50} for photons of our previous study. Results: Minimum latency time was found to be dose-dependent, but not significantly LET-dependent. The TD{sub 50} values for the onset of paresis grade 2 within 300 days were 19.5 ± 0.4 Gy (16 keV/μm), 18.4 ± 0.4 Gy (21 keV/μm), 17.7 ± 0.3 Gy (36 keV/μm), 16.1 ± 1.2 Gy (45 keV/μm), 14.6 ± 0.5 Gy (66 keV/μm), and 14.8 ± 0.5 Gy (99 keV/μm). The corresponding RBEs increased from 1.26 ± 0.05 (16 keV/μm) up to 1.68 ± 0.08 at 66 keV/μm. Unexpectedly, the RBE at 99 keV/μm was comparable to that at 66 keV/μm. Conclusions: The data suggest a linear relation between RBE and LET at high doses for late effects in the spinal cord. Together with additional data from ongoing fractionated irradiation experiments, these data will provide an extended database to systematically benchmark RBE models for further improvements of carbon ion treatment planning.

    Many of the early Cretaceous intrusive complexes in the Damaraland of west-central Namibia are silicic in composition. Although all have trace element characteristics typical for the so-called A-type granites, major differences in alkali/aluminum ratios and isotopic compositions require diverse magma sources. This paper presents Nd and O isotope data from the five largest silicic complexes (Paresis, Erongo, Brandberg, Cape Cross, Gross Spitzkoppe) that provide new constraints on the nature of crustal and mantle sources involved, and their relative proportions. The Paresis complex has an isotopic signature ( δ18O=+9‰, ɛNd 130 Ma=-21) indicating a crustal component similar to Mesoproterozoic gneisses of the Angola craton. The other complexes have isotope variations ( δ18O from +8.1‰ to +10.7‰ and ɛNd 130 Ma from -1 to -9) that can be explained by a binary mixing model between a mantle and crustal component. More importantly, this same mixing line also fits the Nd-O isotope variations reported from the mafic Okenyenya and Messum complexes, and from rhyodacites in the southern Etendeka volcanic sequence. The uniformity of the crustal component implied by this mixing model suggests lower crustal material, in contrast to the geologic complexity of the Neoproterozoic Damara Belt presently exposed at the surface. This is consistent with the isotopic data, and we interpret the crustal component to be lower crustal metametasediments that were dehydrated and perhaps melt-depleted by generation of the S-type granites, which are widespread in the Damara Belt. The mantle component is interpreted to be dominated by the Tristan mantle plume, but some involvement of depleted mantle material is needed to explain all of the isotope data. The data rule out any significant role for enriched, subcontinental mantle lithosphere. All silicic Damaraland complexes, as well as the Etendeka rhyodacites, classify as A-type granites despite their proven source diversity. This means

  14. Comparing unilateral and bilateral upper limb training: The ULTRA-stroke program design

    2009-01-01

    Background About 80% of all stroke survivors have an upper limb paresis immediately after stroke, only about a third of whom (30 to 40%) regain some dexterity within six months following conventional treatment programs. Of late, however, two recently developed interventions - constraint-induced movement therapy (CIMT) and bilateral arm training with rhythmic auditory cueing (BATRAC) - have shown promising results in the treatment of upper limb paresis in chronic stroke patients. The ULTRA-stroke (acronym for Upper Limb TRaining After stroke) program was conceived to assess the effectiveness of these interventions in subacute stroke patients and to examine how the observed changes in sensori-motor functioning relate to changes in stroke recovery mechanisms associated with peripheral stiffness, interlimb interactions, and cortical inter- and intrahemispheric networks. The present paper describes the design of this single-blinded randomized clinical trial (RCT), which has recently started and will take several years to complete. Methods/Design Sixty patients with a first ever stroke will be recruited. Patients will be stratified in terms of their remaining motor ability at the distal part of the arm (i.e., wrist and finger movements) and randomized over three intervention groups receiving modified CIMT, modified BATRAC, or an equally intensive (i.e., dose-matched) conventional treatment program for 6 weeks. Primary outcome variable is the score on the Action Research Arm test (ARAT), which will be assessed before, directly after, and 6 weeks after the intervention. During those test sessions all patients will also undergo measurements aimed at investigating the associated recovery mechanisms using haptic robots and magneto-encephalography (MEG). Discussion ULTRA-stroke is a 3-year translational research program which aims (1) to assess the relative effectiveness of the three interventions, on a group level but also as a function of patient characteristics, and (2) to

    A local anaesthetic drug was injected around the peroneal nerve in healthy subjects in order to investigate whether the resulting loss in foot dorsiflexion power in part depended on a gamma-fibre block preventing 'internal' activation of spindle end-organs and thereby depriving the alpha-motoneurones of an excitatory spindle inflow during contraction. The motor outcome of maximal dorsiflexion efforts was assessed by measuring firing rates of individual motor units in the anterior tibial (t.a.) muscle, mean voltage e.m.g. from the pretibial muscles, dorsiflexion force and range of voluntary foot dorsiflexion movements. The tests were performed with and without peripheral conditioning stimuli, such as agonist or antagonist muscle vibration or imposed stretch of the contracting muscles. As compared to control values of t.a. motor unit firing rates in maximal isometric voluntary contractions, the firing rates were lower and more irregular during maximal dorsiflexion efforts performed during subtotal peroneal nerve blocks. During the development of paresis a gradual reduction of motor unit firing rates was observed before the units ceased responding to the voluntary commands. This change in motor unit behaviour was accompanied by a reduction of the mean voltage e.m.g. activity in the pretibial muscles. At a given stage of anaesthesia the e.m.g. responses to maximal voluntary efforts were more affected than the responses evoked by electric nerve stimuli delivered proximal to the block, indicating that impaired impulse transmission in alpha motor fibres was not the sole cause of the paresis. The inability to generate high and regular motor unit firing rates during peroneal nerve blocks was accentuated by vibration applied over the antagonistic calf muscles. By contrast, in eight out of ten experiments agonist stretch or vibration caused an enhancement of motor unit firing during the maximal force tasks. The reverse effects of agonist and antagonist vibration on the

    Background: Pulmonary arterial hypertension (PAH) is a rare disease with a predilection for young women that is associated with right ventricular failure and premature death. PAH can complicate pregnancy with hemodynamic instability or sudden death during parturition and postpartum. Our aim was to examine the impact of PAH on pregnancy outcomes in the modern era. Methods: We conducted a retrospective evaluation of pregnant patients with PAH managed between 1999 and 2009 at five US medical centers. Patient demographics, medical therapies, hemodynamic measurements, manner of delivery, anesthetic administration, and outcomes were assessed. Results: Among 18 patients with PAH, 12 continued pregnancy and six underwent pregnancy termination. Right ventricular systolic pressure in patients managed to parturition was 82 ± 5 mm Hg and in patients with pregnancy termination was 90 ± 16 mm Hg. Six patients underwent pregnancy termination at mean gestational age of 13 ± 1.0 weeks with no maternal deaths or complications. Twelve patients elected to continue their pregnancy and were hospitalized at 29 ± 1.4 weeks. PAH-specific therapy was administered to nine (75%) at time of delivery consisting of sildenafil, IV prostanoids, or combination therapy. All parturients underwent Cesarean section at 34 weeks with one in-hospital death and one additional death 2 months postpartum for maternal mortality of 16.7%. Conclusions: Compared with earlier reports, maternal morbidity and mortality among pregnant women with PAH was reduced, yet maternal complications remain significant and patients should continue to be counseled to avoid pregnancy.

    Background and Aims: Endotracheal intubation can produce severe maternal haemodynamic changes during caesarean sections under general anaesthesia. However, administration of narcotics before endotracheal intubation to prevent these changes may affect the Apgar score in neonates. This study was designed to evaluate the effect of intravenous alfentanil on haemodynamic changes due to endotracheal intubation in elective caesarean sections performed under general anaesthesia. Methods: Fifty parturients were randomly divided into two equal groups. Patients in the first group received alfentanil 10 μg/kg and in the second group received placebo intravenously 1 min before induction of anaesthesia for elective caesarean section. Haemodynamic parameters and bispectral index system (BIS) in mothers, peripheral capillary oxygen saturation (SpO2) and Apgar score in the newborn were assessed. Results: Changes in systolic blood pressure were significant at 1, 5 and 10 min after intubation between two groups. Changes in diastolic blood pressure were significantly less in alfentanil group, 1 min after induction of anaesthesia and 1 min after endotracheal intubation. Mean heart rate at 1 min after induction and at 1 and 5 min after intubation also reduced significantly in this group. Conclusion: Alfentanil use was associated with decreases or minimal increases in maternal systolic and diastolic blood pressures and heart rate after endotracheal intubation. PMID:26755838

    The indigenous people of coastal areas show a low percentage of low chlorinated and dioxin-like PCB congeners (as opposed to mainland aborigines) with a significant proportion of the "triad" in the amount of PCBs. 5 years after the first survey the ratio of the analyzed groups of PCB congeners in the blood of parturients - mothers, as well as in the fetus - child in the coastal Chukotka remained unchanged, indicating that the equal share rate of clearance-accumulation of congeners and is almost equal share content of PCB congeners in the mother and child. The average duration of half-lives of PCB congeners (#105-187) from the mother's body was 4-6 years (for the sum of PCBs - 5.7 years), which is broadly consistent with the results of foreign studies. The composition of PCB congeners in the blood of the continental population significantly differs from those in the food, while coastal residents--similar to the composition of PCBs in marine mammals. The content of PCB congeners in the domestic sources of pollution has no resemblance to the composition of PCBs in the blood of the natives. PMID:23082663

    We have performed a randomized, double-blind comparison of two epidural drug regimens for analgesia in labour. In the bupivacaine group (BUPIV), 101 healthy parturients received 0.1% bupivacaine with fentanyl 2 microg ml(-1). In the ropivacaine group (ROPIV), 102 women received 0.2% ropivacaine. Both groups received an initial loading dose of 15 ml, a continuous infusion of 8 ml h(-1), and top-ups of 10 ml. Breakthrough pain not responding to a routine top-up was treated with an 'escape' top-up of 10 ml 0.25% bupivacaine. The two groups were compared for complete analgesia at 30 min, routine and 'escape' top-up requirements, midwife assessment of analgesic efficacy, delivery mode, patient visual analogue scores (VAS) for first and second stage analgesia, overall satisfaction, and patient assessment of motor blockade. Patients receiving ropivacaine received fewer routine top-ups (median 1.0 vs. 2.0, P=0.001) and fewer escape top-ups (9.8% vs. 21.8%, P=0.02). The ropivacaine group was more likely to be pain free in the first stage (51% vs. 33.7%, P=0.01). There were no significant differences in patients' assessment of motor block or mode of delivery between the groups. Pain relief and satisfaction scores from midwives and patients were consistently better in the ropivacaine group, but did not reach statistical significance. PMID:11732513

    Patient-controlled epidural analgesia (PCEA) for labor was introduced into clinical practice 20 yr ago. The PCEA technique has been shown to have significant benefits when compared with continuous epidural infusion. We conducted a systematic review using MEDLINE and EMBASE (1988-April 1, 2008) of all randomized, controlled trials in parturients who received PCEA in labor in which one of the following comparisons were made: background infusion versus none; ropivacaine versus bupivacaine; high versus low concentrations of local anesthetics; and new strategies versus standard strategies. The outcomes of interest were maternal analgesia, satisfaction, motor block, and the incidence of unscheduled clinician interventions. A continuous background infusion improved maternal analgesia and reduced unscheduled clinician interventions. Larger bolus doses (more than 5 mL) may provide better analgesia compared with small boluses. Low concentrations of bupivacaine or ropivacaine provide excellent analgesia without significant motor block. Many strategies with PCEA can provide effective labor analgesia. High volume, dilute local anesthetic solutions with a continuous background infusion appear to be the most successful strategy. Research into new delivery strategies, such as mandatory programmed intermittent boluses and computerized feedback dosing, is ongoing. PMID:19224805

    We compared the effects of continuous epidural infusion of ropivacaine 0.25% with bupivacaine 0.25% on pain relief and motor block during labor, and on the neonate. Seventy-six full-term parturients in active labor requiring epidural analgesia were randomly allocated to receive either bupivacaine 0.25% or ropivacaine 0.25%. Fifteen minutes after a loading dose of 10 mL of the study drug, an epidural infusion with the same drug was started at 6-12 mL/h to maintain an adequate block. Top-up doses of 6-10 mL were given as required. At full cervical dilation, the epidural infusion was discontinued. The onset of pain relief (verbal scale), contraction pain (visual analog scale), intensity of motor block (modified Bromage scale), and duration of motor block were not statistically different between the groups. Apgar scores at 1 and 5 min after delivery were comparable. There was a higher proportion of the neonates in the ropivacaine group (26/31 = 84%) who had a neurologic and adaptive capacity score (NACS) > or = 35 2 h after delivery than in the bupivacaine group (18/29 = 62%). We conclude that ropivacaine 0.25% and bupivacaine 0.25% are equally effective for epidural pain relief during labor. Ropivacaine may have an advantage over bupivacaine regarding neonatal neurobehavioral performance during the first few hours after delivery, although further studies will be required to substantiate this.

    Background. Childbirth medicalization has reduced the parturient's opportunity to labour and deliver in a spontaneous position, constricting her to assume the recumbent one. The aim of the study was to compare recumbent and alternative positions in terms of labour process, type of delivery, neonatal wellbeing, and intrapartum fetal head rotation. Methods. We conducted an observational cohort study on women at pregnancy term. Primiparous women with physiological pregnancies and single cephalic fetuses were eligible for the study. We considered data about maternal-general characteristics, labour process, type of delivery, and neonatal wellbeing at birth. Patients were divided into two groups: Group-A if they spent more than 50% of labour in a recumbent position and Group-B when in alternative ones. Results. 225 women were recruited (69 in Group-A and 156 in Group-B). We found significant differences between the groups in terms of labour length, Numeric Rating Scale score and analgesia request rate, type of delivery, need of episiotomy, and fetal occiput rotation. No differences were found in terms of neonatal outcomes. Conclusion. Alternative maternal positioning may positively influence labour process reducing maternal pain, operative vaginal delivery, caesarean section, and episiotomy rate. Women should be encouraged to move and deliver in the most comfortable position. PMID:24955365

    To evaluate the analgesic efficacy of local anesthetic infiltration, 20 parturients scheduled for elective minilaparotomy and bilateral tubal ligation with either spinal or epidural anesthesia participated in this prospective, randomized, controlled, double-blind trial. All patients received intravenous (iv) metoclopramide 10 mg and ketorolac 60 mg intraoperatively, as well as preincisional infiltration of the infraumbilical skin incision with 0.5% bupivacaine. Infiltration of bilateral uterine tubes and mesosalpinx was performed either with 0.5% bupivacaine (n = 10) or isotonic sodium chloride solution (n = 10). Intravenous meperidine (25 mg every 3 minutes as needed) was given to treat pain in the postanesthesia care unit (PACU). The total amount of meperidine administered in the PACU was significantly larger in the saline group than in the bupivacaine group. Pain scores at 30, 45, 60, 75, and 90 minutes postoperatively and on the 7th postoperative day were significantly lower in the bupivacaine group than in the saline group. During tubal ligation, infiltration of uterine tubes and mesosalpinx with 0.5% bupivacaine significantly enhanced analgesia both immediately postoperatively and on the 7th postoperative day compared with infiltration with sodium chloride. In conclusion, this study proved that during bilateral tubal ligation with either spinal or epidural anesthesia, preemptive analgesia using iv ketorolac, iv metoclopramide, and infiltration of the incised skin and uterine tubes with 0.5% bupivacaine can eliminate pain, nausea, vomiting, or cramping and maintain good analgesia for 7 days postoperatively.

    OBJECTIVE To analyze the effects of acupressure at the SP6 point on labor duration and cesarean section rates in parturients served in a public maternity hospital. METHODS This controlled, randomized, double-blind, pragmatic clinical trial involved 156 participants with gestational age ≥ 37 weeks, cervical dilation ≥ 4 cm, and ≥ 2 contractions in 10 min. The women were randomly divided into an acupressure, placebo, or control group at a university hospital in an inland city in the state of Sao Paulo, Brazil, in 2013. Acupressure was applied to the SP6 point during contractions for 20 min. RESULTS The average labor duration was significantly different between the SP6 acupressure group [221.5 min (SD = 162.4)] versus placebo [397.9 min (SD = 265.6)] and versus control [381.9 min (SD = 358.3)] (p = 0.0047); however, the groups were similar regarding the cesarean section rates (p = 0.2526) and Apgar scores in the first minute (p = 0.9542) and the fifth minute (p = 0.7218) of life of the neonate. CONCLUSIONS The SP6 acupressure point proved to be a complementary measure to induce labor and may shorten the labor duration without causing adverse effects to the mother or the newborn. However, it did not affect the cesarean section rate. PMID:25741644

    We evaluated 2-chloroprocaine, three per cent, in 44 women having epidural anaesthesia for Caesarean section. All subjects received a minimum dose of 25 ml (750 mg) in increments designed to allow early recognition of accidental subarachnoid or intravascular injection. Further increments were given as needed to achieve a T5 sensory level or higher. We recorded pulse and blood pressure at two-minute intervals and used a simple pain scale to assess analgesia. Ninety-three per cent of subjects had acceptable analgesia. Seventeen mothers required more than 25 ml to attain a T5 level; subjects having a BMI (body mass index) equal to or greater than 35, or over 35 years of age, demonstrated more cephalad spread. Hypotension (MAP 80 per cent of control or less) occurred in 24, mothers (54 per cent), often transiently, but an infused fluid volume exceeding 30 ml X kg-1 at delivery significantly reduced post-delivery hypotension. Nausea and vomiting accompanied the hypotension in 12 mothers. No neonatal depression occurred. We conclude the incremental administration of chloroprocaine, as described, permits safe administration of the drug, with excellent analgesia in most parturients. PMID:6498571

At 31 December 1987, 103 AIDS cases have been recorded, 86% by heterosexual transmission. The first case dated May 1979 was retroactively diagnosed in an Haitian parturient, thank to her serum kept in the Pasteur institute of Cayenne. 44 women got their pregnancy during their HIV infection: 5 with clinical and biological evidence of AIDS, 7 developed AIDS after getting pregnant, and 10 out of these 12 women died. All of them were from a rather low social group and, generally, were not married. 43 are black (40 Haitians and 3 Guyanese Creoles), one is Indian and presented some psychic disorders. The mean age was 32 1/2 (from 15 to 51 years old). 55 babies were born: 12 developed AIDS (6 died during the first 15 months of their life); 14 are HIV +, 3 stillborns, 4 never tested and 22 developed negative reaction (with ELISA and Western-Blot) between 7.5 and 10 months of their life.

    OBJECTIVE: Our intention is to determine newborn costs and lengths of stay attributable to prenatal exposure to cocaine and other illicit drugs. DATA SOURCES AND STUDY SETTING: All parturients who delivered at a large municipal hospital in New York City between November 18, 1991 and April 11, 1992. STUDY DESIGN: A cross-sectional analysis used multivariate, loglinear regressions to analyze differences in costs and length of stay between infants exposed and unexposed prenatally to cocaine and other illicit drugs, adjusting for maternal race, age, prenatal care, tobacco, parity, type of delivery, birth weight, prematurity, and newborn infection. DATA COLLECTION/EXTRACTION METHODS: Urine specimens, with linked obstetric sheets and discharge abstracts, provided information on exposure, prenatal behaviors, costs, length of stay, and discharge disposition. PRINCIPAL FINDINGS: Infants exposed to cocaine or some other illicit drug stay approximately seven days longer at a cost of $7,731 more than infants unexposed. Approximately 60 percent of these costs are indirect, the result of adverse birth outcomes and newborn infection. Hospital screening as recorded on discharge abstracts substantially underestimates prevalence at delivery, but overestimates its impact on costs. PMID:7782220

    Despite their importance for understanding predator–prey interactions, factors that affect predator evasion behaviours of offspring of large ungulates are poorly understood. Our objective was to characterize the influence of selection and availability of escape cover and maternal presence on predator evasion by white-tailed deer, Odocoileus virginianus, fawns in the northern Great Plains, U.S.A. We observed 45 coyote, Canis latrans, chases of fawns, and we participated in 83 human chases of fawns during 2007–2009, of which, 19 and 42 chases, respectively, ended with capture of the fawn. Evasive techniques used by fawns were similar for human and coyote chases. Likelihood of a white-tailed deer fawn escaping capture, however, was influenced by deer group size and a number of antipredator behaviours, including aggressive defence by females, initial habitat and selection of escape cover, all of which were modified by the presence of parturient females. At the initiation of a chase, fawns in grasslands were more likely to escape, whereas fawns in forested cover, cultivated land or wheat were more likely to be captured by a coyote or human. Fawns fleeing to wetlands and grasslands also were less likely to be captured compared with those choosing forested cover, wheat and cultivated land. Increased probability of capture was associated with greater distance to wetland and grassland habitats and decreased distance to wheat. Use of wetland habitat as a successful antipredator strategy highlights the need for a greater understanding of the importance of habitat complexity in predator avoidance.

    Introduction Congenital bicuspid aortic valve with severe aortic stenosis (AS) is a rare condition (3–6% of patients with congenital heart disease). Pregnancy in these patients carries a high risk of maternal and fetal mortality. With advancing gestational age, these women may develop cardiac failure due to increased cardiorespiratory requirements. When medical therapy proves insufficient, cardiac surgery becomes mandatory to save the patient's life. Balloon valvuloplasty is only palliative treatment, the duration of benefit being only 6 months. Valve replacement is thus recommended. Cardiopulmonary bypass (CPB) surgery with valve replacement has been reported to carry a lower risk of maternal mortality (1.5–13%) but a very high fetal risk (16–40%). This paper reports the case of a 30-year-old primigravida with severe AS with bicuspid aortic valve and pulmonary congestion clinically uncontrolled, in whom CPB surgery and aortic valve replacement was performed as an emergency procedure, along with a lower segment Caesarian section. Conclusion The outcome of unrelieved severe symptomatic AS in pregnancy is poor. Multidisciplinary management is important to avoid deterioration in cardiac performance in parturients with severe AS. CPB during pregnancy carries a high risk to the fetus. Therefore, open heart surgery during pregnancy should be advised only in extreme emergencies (ie, heart failure refractory to conventional therapy).

    Acute fetal distress in labour is a condition of progressive fetal asphyxia with hypoxia and acidosis. It is usually diagnosed by finding characteristic features in the fetal heart rate pattern, wherever possible supported by fetal scalp pH measurement. Intrauterine resuscitation consists of applying specific measures with the aim of increasing oxygen delivery to the placenta and umbilical blood flow, in order to reverse hypoxia and acidosis. These measures include initial left lateral recumbent positioning followed by right lateral or knee-elbow if necessary, rapid intravenous infusion of a litre of non-glucose crystalloid, maternal oxygen administration at the highest practical inspired percentage, inhibition of uterine contractions usually with subcutaneous or intravenous terbutaline 250 microg, and intra-amniotic infusion of warmed crystalloid solution. Specific manoeuvres for umbilical cord prolapse are also described. Intrauterine resuscitation may be used as part of the obstetric management of labour, while preparing for caesarean delivery for fetal distress, or at the time of establishment of regional analgesia during labour in the compromised fetus. The principles may also be applied during inter-hospital transfers of sick or labouring parturients. PMID:15321562

    Post-parturient insulin resistance (IR) is a common feature in all mammalian animals. However, in dairy cows, it can be exacerbated because of high milk yield, leading to excessive negative energy balance, which is related with increased disease incidence, reduced milk production and worsened reproductive performance. IR has been extensively investigated in humans suffering from diabetes mellitus. In these subjects, it is known that oxidative stress (OS) plays a causative role in the onset of IR. Although OS occurs in transitional dairy cattle, there are yet no studies that investigated the association between IR and OS in dairy cattle. Therefore, the aim of this study was to investigate whether there is a relationship between OS and IR in dairy cattle. Serum samples were taken repeatedly from 22 dairy cows from 2 months prior to the expected calving date to 2 months after calving and were analysed for markers of metabolic and redox balance. Surrogate indices of insulin sensitivity were also calculated. Generalised linear mixed models revealed an effect of the oxidative status on peripheral insulin concentration and on indices of insulin sensitivity. Hence, field trials should investigate the effectiveness of antioxidant therapy on insulin sensitivity in peripheral tissues during the transition period of dairy cattle. PMID:26174108

    Intraspecific killing has been reported among polar bears (Ursus maritimus), brown bears (U. arctos), and black bears (U. americanus). Although cannibalism is one motivation for such killings, the ecological factors mediating such events are poorly understood. Between 24 January and 10 April 2004, we confirmed three instances of intraspecific predation and cannibalism in the Beaufort Sea. One of these, the first of this type ever reported for polar bears, was a parturient female killed at her maternal den. The predating bear was hunting in a known maternal denning area and apparently discovered the den by scent. A second predation event involved an adult female and cub recently emerged from their den, and the third involved a yearling male. During 24 years of research on polar bears in the southern Beaufort Sea region of northern Alaska and 34 years in northwestern Canada, we have not seen other incidents of polar bears stalking, killing, and eating other polar bears. We hypothesize that nutritional stresses related to the longer ice-free seasons that have occurred in the Beaufort Sea in recent years may have led to the cannibalism incidents we observed in 2004. ??

    Purpose. The purpose of this study was to compare the analgesic properties of levobupivacaine with or without fentanyl for patient-controlled epidural analgesia after Cesarean section in a randomized, double-blinded study. Methods. We enrolled American Society of Anesthesiologists class I/II, full-term pregnant women at National Taiwan University Hospital who received patient-controlled epidural analgesia after Cesarean section between 2009 and 2010. Eighty women were randomly assigned into two groups. In group A, the 40 subjects received drug solutions made of 0.6 mg/ml levobupivacaine plus 2 mcg/ml fentanyl, and in group B the 40 subjects received 1 mg/ml levobupivacaine. Maintenance was self-administered boluses and a continuous background infusion. Results. There were no significant differences in the resting and dynamic pain scales and total volume of drug used between the two groups. Patient satisfaction was good in both groups. Conclusion. Our study showed that pure epidural levobupivacaine can provide comparative analgesic properties to the levobupivacaine-fentanyl combination after Cesarean section. Pure levobupivacaine may serve as an alternative pain control regimen to avoid opioid-related adverse events in parturients. PMID:24982917

    In order to map the mental state in the early puerperium the authors gave to a group of 100 women for five days after delivery Lüscher's colour test. Based on the assembled data a tentative average norm for the post-partum state was elaborated: 54312067 (i.e. violet, yellow, red, blue, green, grey, brown, black). Deviations from the norm were found in the following groups of parturient women: Caesarean sections 31540276 (p less than 0.05, n = 9), single and divorced 34512067 (NS), duration of the first stage of labour more than 360 mins. 51423067 (p less than 0.01, n = 29) or less than 180 mins. 34512067 (p less than 0.001, n = 22), more than one delivery 34512067 (p less than 0.01, n = 52) and university graduates 43152607 (p less than 0.001, n = 31). The above norm could be used after verification on a more numerous population group as a simple diagnostic means of unsatisfactory experience during the early puerperium. PMID:2136409

    Q fever is a zoonotic disease caused by the bacterium Coxiella burnetii which is endemic in cattle, sheep and goats in much of the world, including the United Kingdom (UK). There is some epidemiological evidence that a small proportion of cases in the developed world may arise from consumption of unpasteurised milk with less evidence for milk products such as cheese. Long maturation at low pH may give some inactivation in hard cheese, and viable C. burnetii are rarely detected in unpasteurised cheese compared to unpasteurised milk. Simulations presented here predict that the probability of exposure per person to one or more C. burnetii through the daily cumulative consumption of raw milk in the UK is 0·4203. For those positive exposures, the average level of exposure predicted is high at 1266 guinea pig intraperitoneal infectious dose 50% units (GP_IP_ID50 ) per person per day. However, in the absence of human dose-response data, the case is made that the GP_IP_ID50 unit represents a very low risk through the oral route. The available evidence suggests that the risks from C. burnetii through consumption of unpasteurised milk and milk products (including cheese) are not negligible but they are lower in comparison to transmission via inhalation of aerosols from parturient products and livestock contact.

    Continuous oxygen saturation measurements were obtained in 103 pregnant patients and 96 of their newborns by a pulse oximeter during the peripartum period. The parturients received narcotic sedation; epidural, spinal, or general anesthesia; or no analgesia. Seventy-nine patients had oxygen saturation levels over 90% (mean 97.6%), and 24 had one or more oxygen saturation levels less than or equal to 90% (mean 95.6%, P = .001). For all neonates, the mean oxygen saturation was in the "hypoxic range" at one minute (77.6 +/- 11.48%), five minutes (84.4 +/- 7.64%), and ten minutes (89.4 +/- 6.29%). More desaturation episodes were noted in mothers exposed to a central nervous system depressant (P = .041). When mothers with and without desaturation events were compared, no differences were found for age, parity, race, hematocrit, smoking, hypotensive episodes, or delivery route. More maternal desaturation episodes occurred during transport (P = .0016) and while in the recovery room (P = .0003) than in other study periods. Maternal peripartum desaturation events occurred without adverse neonatal effect when prompt treatment was provided. Neonatal hemoglobin oxygen saturation less than or equal to 90% is commonly found within ten minutes after birth and does not always merit the designation of "hypoxia." PMID:3347419

    Objective: This study was to determine the optimal dosage of ondansetron for preventing maternal hypotension during cesarean delivery. Methods: One hundred and fifty parturient women scheduled for elective cesarean section were randomly assigned to five groups (n=30). Five minutes prior to spinal anesthesia, women were injected with 5 ml of physiological saline (S), 2 mg (O2), 4 mg (O4), 6 mg (O6), or 8 mg (O8) of ondansetron in saline, respectively. Maternal blood pressure and heart rate were measured at 2-min intervals for 30 min. The serum parameters in umbilical cord blood were analyzed after delivery. Results: Compared with group S, the incidence of maternal hypotension was significantly lower in groups O4 and O6 (P < 0.05). The umbilical venous pH was significantly higher in group O4 (P < 0.05); while the partial pressure of carbon dioxide (Pco2) was significantly lower in groups O4, O6, and O8 (P < 0.05); and the bicarbonate (Hco3 -) and base excess in extracellular fluid (BEecf) were significantly lower in groups O6 and O8 (P < 0.05). Moreover, minimal changes of systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure were observed in group O4 (P < 0.05). Conclusion: The optimal dose of ondansetron preloading was 4 mg during cesarean delivery. PMID:25664023

    Background and Aims: Patients undergoing elective cesarean delivery (CD) have a high-risk of spinal-induced hypotension (SIH). We hypothesized that a colloid preload would further reduce SIH when compared with a crystalloid preload. Material and Methods: Eighty-two healthy parturients undergoing elective CD were included in the study. Patients were randomly assigned to two groups (41 patients in each group) to receive either Lactated Ringer's solution (1500 ml) or hydroxyethyl starch (6% in normal saline, 500 ml) 30 min prior to placement of spinal anesthesia. All patients were treated with a phenylephrine infusion (100 mcg/min), titrated during the study. Results: There was no statistical difference between groups with regards to the incidence of hypotension (10.8% in the colloid group vs. 27.0% in the crystalloid group, P = 0.12). There was also no difference between groups with respect to bradycardia, APGAR scores, and nausea and vomiting. Significantly less phenylephrine (1077.5 ± 514 mcg) was used in the colloid group than the crystalloid group (1477 ± 591 mcg, P = 0.003). Conclusion: The preload with 6% of hydroxyethyl starch before CD might be beneficial for the prevention of SIH. PMID:27625478

    Labor progression is routinely assessed through transvaginal digital inspections, meaning that the clinical decisions taken during the most delicate phase of pregnancy are subjective and scarcely supported by technological devices. In response to such inadequacies, we combined intrapartum echographic acquisitions with advanced tracking algorithms in a new method for noninvasive, quantitative, and automatic monitoring of labor. Aim of this work is the preliminary clinical validation and accuracy evaluation of our automatic algorithm in assessing progression angle (PA) and fetal head station (FHS). A cohort of 10 parturients underwent conventional labor management, with additional translabial echographic examinations after each uterine contraction. PA and FHS were evaluated by our automatic algorithm on the acquired images. Additionally, an experienced clinical sonographer, blinded regarding the algorithm results, quantified on the same acquisitions of the two parameters through manual contouring, which were considered as the standard reference in the evaluation of automatic algorithm and routine method accuracies. The automatic algorithm (mean error ± 2SD) provided a global accuracy of 0.9 ± 4.0 mm for FHS and 4° ± 9° for PA, which is far above the diagnostic ability shown by the routine method, and therefore it resulted in a reliable method for earlier identification of abnormal labor patterns in support of clinical decisions.

    Recent studies have shown that nasal oxygen delivery can prolong the time to desaturation during apnoea in the non-pregnant population. We investigated the benefits of apnoeic oxygenation during rapid sequence induction in the obstetric population using computational modelling. We used the Nottingham Physiology Simulator, and pre-oxygenated seven models of pregnancy for 3 min using Fi O2 1.0, before inducing apnoea. We found that increasing Fi O2 at the open glottis increased the time to desaturation, extending the time taken for Sa O2 to reach 40% from 4.5 min to 58 min in the average parturient model (not in labour). Our study suggests that a small increase in time to desaturation could be achieved at Fi O2 0.4-0.6, which could be delivered by standard nasal cannulae. The greatest increases in time to desaturation were seen at Fi O2 1.0, which could be delivered by high-flow nasal cannulae under ideal conditions. PMID:27440389

    Introduction: Patient involvement in safe delivery planning is considered important yet not widely practiced. The present study aimed at identifythe factors that affect patient involvementin safe delivery, as recommended by parturient women. Methods: This study was part of a qualitative research conducted by content analysis method and purposive sampling in 2013. The data were collected through 63 semi-structured interviews in4 hospitalsand analyzed using thematic content analysis. The participants in this research were women before discharge and after delivery. Findings were analyzed using Colaizzi’s method. Results: Four categories of factors that could affect patient involvement in safe delivery emerged from our analysis: patient-related (true and false beliefs, literacy, privacy, respect for patient), illness-related (pain, type of delivery, patient safety incidents), health care professional-relatedand task-related factors (behavior, monitoring &training), health care setting-related (financial aspects, facilities). Conclusion More research is needed to explore the factors affecting the participation of mothers. It is therefore, recommended to: 1) take notice of mother education, their husbands, midwives and specialists; 2) provide pregnant women with insurance coverage from the outset of pregnancy, especially during prenatal period; 3) form a labor pain committee consisting of midwives, obstetricians, and anesthesiologists in order to identify the preferred painless labor methods based on the existing facilities and conditions, 4) carry out research on observing patients’ privacy and dignity; 5) pay more attention on the factors affecting cesarean.

    Experiments with 120 mongrel dogs were aimed at the assessment of radio protective strength of indralin and local shielding of the pelvic marrow from 2.5 Gy, and also their concurrent use for the dogs irradiated by protons (240 MeV) at absolutely lethal and over-lethal 4 Gy and 5 Gy. Clinical observations, hematological investigations and ECG analysis of survived animals were conducted 4.5 years post the irradiation. Dogs that remained healthy following 3.5 to 4.5 years since the irradiation were sacrificed for pathomorphological investigations. The radioprotective effect of local shielding against 4 Gy was weak while this effect of intramuscular indralin (10, 20, 40 mg/kg of body) was significant reaching 50 to 67.7%. The concurrent use of two methods had, apparently, potentiated the 100% radioprotection of the animals irradiated by overlethal 5 Gy. Blood investigations of the survived dogs every 2-4 months evidenced that complete recovery of the total leukocyte count had taken 9 to 13 months. Also, dogs' pregnancy in 9-10 months since the beginning of irradiation pointed to maintenance of fertility and the ability to parturiate 2 or 3 times yielding 5-6 live cubs. Necropsy of the dogs did not reveal gross macroscopic structural changes of visceral organs or tissues. Seven out of 27 sacrificed dogs had benign tumors infrequent in intact dogs at this age.

    Virgin female hamsters were mated and tested once daily for maternal retrieving behavior beginning on days 0, 5, 9, 13, 15, of the 16 day gestation period to determine if responsiveness toward newborn pups changes as pregnancy proceeds. Upon initial exposure to 3 newborn pups, only a small percentage of early-to-mid-pregnant females exhibited maternal retrieving behavior spontaneously. In contrast, over half of the 15 day pregnant females displayed retrieving during the first test. Despite the high frequency of initial pup-directed aggression and cannibalism, maternal retrieval was induced in the majority of the females in all groups by repeated daily exposure to 3 newborn pups. However, no significant differences were observed in the number of pup exposure periods required to induce maternal retrieving in 0, 5, and 9 day pregnant females. It is concluded that the high level of maternal responsiveness observed in the parturient hamster develops somewhat abruptly during late pregnancy. In this respect, the pattern observed in the hamster differs from the more gradual increase in maternal responsiveness reported in mid-to-late-pregnant mice and rats. PMID:6540458

    Background: To compare the effects of addition of Clonidine (60 μg) to Epidural Bupivacaine (0.125%) for labour analgesia, with regard to duration of analgesia, duration of labour, ambulation, incidence of instrumentation and caesarean section, foetal outcome, patient satisfaction and side effects. Patients & Methods: On demand, epidural labour analgesia was given to 50 nulliparous healthy term parturients (cephalic presentation), divided in two groups randomly. Group I received bupivacaine (0.125%) alone, whereas Group II received bupivacaine (0.125%) along with Clonidine (60 μg). 10 ml of 0.125% bupivacaine was injected as first dose and further doses titrated with patient relief (Numerical Rating Scale <3). Top ups were given whenever Numerical Rating Scale went above 5. Results: There was statistically significant prolongation of duration of analgesia in Group II, with no difference in duration of labour, ambulation, incidence of instrumentation and caesarean section or foetal outcome. Also clonidine gave dose sparing effect to bupivacaine and there was better patient satisfaction without any significant side effects in Group II. Conclusion: Clonidine is a useful adjunct to bupivacaine for epidural labour analgesia and can be considered as alternative to opioids. PMID:21804714

  6. Epidemiology of rickettsial diseases.

    Rickettsial diseases have a diversity of epidemiologic characteristics reflective of the variety of ecologic situations in which the obligate intracellular bacteria are transmitted to humans. For the spotted fever group (SFG) rickettsiae, Rickettsia typhi, R. tsutsugamushi, Coxiella burnetii, and the human ehrlichial agent, humans are a dead-end host who plays no role in the maintenance of the organism in nature. All rickettsioses exist as zoonoses. Moreover, all rickettsiae are found in infected arthopods, which generally serve as the natural hosts and can transmit the infection to the next generation of ticks, mites, chiggers, or fleas. From our anthropocentric viewpoint, Q fever aerosol infection from parturient animals and Brill-Zinsser disease ignited epidemics of louse-borne epidemic typhus are exceptions. However, silent cycles of C. burnetii in ticks and R. prowazekii in the flying squirrel flea may have maintained these agents in transovarial or enzootic cycles for eons before humans and their domestic animals arrived on the scene. Thus, the epidemiology of rickettsial diseases must be recognized as an unfortunate aberration of the rickettsial economy. Several excellent reviews of rickettsial ecology contain a wealth of useful information. PMID:1884775

    A 35-year-old woman, a non-smoker with a normal body mass index, 'felt wheezy' and developed profound hypoxia 30 min after preterm vaginal delivery at 24+ weeks of gestation. She denied other symptoms, had no fever but was tachycardic and tachypnoeic with normal blood pressure. Pulmonary embolism, amniotic fluid embolism, cardiomyopathy, arrhythmias, sepsis and non-cardiogenic pulmonary oedema were considered as differential diagnoses. Chest X-ray showed an increased pulmonary vasculature, but the blood tests, ECG, echocardiogram and CT pulmonary angiogram were essentially normal. She was managed on a high dependency area with high-flow oxygen and intravenous antibiotics. She improved dramatically and the oxygen requirements dropped to 2 L over the next 4 h. It is plausible that this woman had acute non-cardiogenic pulmonary oedema secondary to a combination of risk factors. This case highlights the importance of a methodical and multidisciplinary approach for a prompt diagnosis and successful treatment of an acutely ill parturient. PMID:24648478

    Background Pain is one of the side effects of episiotomy. The virtual reality (VR) is a non-pharmacological method for pain relief. The purpose of this study was to determine the effect of using video glasses on pain reduction in primiparity women during episiotomy repair. Methods This clinical trial was conducted on 30 primiparous parturient women having labor at Omolbanin Hospital (Mashhad, Iran) during May-July 2012. Samples during episiotomy repair were randomly divided into two equal groups. The intervention group received the usual treatment with VR (video glasses and local infiltration 5 ml solution of lidocaine 2%) and the control group only received local infiltration (5 ml solution of lidocaine 2%). Pain was measured using the Numeric Pain Rating Scale (0-100 scale) before, during and after the episiotomy repair. Data were analyzed using Fisher’s exact test, Chi-square, Mann-Whitney and repeated measures ANOVA tests by SPSS 11.5 software. Results There were statistically significant differences between the pain score during episiotomy repair in both groups (P=0.038). Conclusion Virtual reality is an effective complementary non-pharmacological method to reduce pain during episiotomy repair. Trial Registration Number: IRCT138811063185N1. PMID:25999621

    In 1946, Dr Curtis Mendelson suggested that aspiration during general anesthesia for delivery was avoidable by restricting oral intake during labor. This suggestion proved influential, and restriction of oral intake in labor became the norm. These limitations may contribute to fear and feelings of intimidation among parturients. Modern obstetrics, especially in the setting of advances in obstetric anesthesia, does not mirror the clinical landscape of Mendelson; hence, one is left to question if his findings remain relevant or if they should inform current recommendations. The use of general anesthesia at time of cesarean delivery has seen a remarkable decline with increased use of effective neuraxial analgesia as the standard of care in modern obstetric anesthesia. While the American College of Obstetricians and Gynecologists now endorses clear liquids during labor, current recommendations continue to suggest that solid food intake should be avoided. Recent evidence from a systematic review involving 3130 women in active labor suggests that oral intake should not be restricted in women at low risk of complications, given there were no identified benefits or harms of a liberal diet. Aspiration and other adverse maternal outcomes may be unrelated to oral intake in labor and as such, qualitative measures such as patient satisfaction should be paramount. It is time to reassess the impact of oral intake restriction during labor given the minimal risk of aspiration during labor in the setting of modern obstetric anesthesia practices. PMID:26812080

    2013-01-01

    Background The frequency of pregnancy-associated malaria is increasingly being documented in American countries. In Colombia, with higher frequency of Plasmodium vivax over Plasmodium falciparum infection, recent reports confirmed gestational malaria as a serious public health problem. Thick smear examination is the gold standard to diagnose malaria in endemic settings, but in recent years, molecular diagnostic methods have contributed to elucidate the dimension of the problem of gestational malaria. The study was aimed at exploring the prevalence of gestational, placental and congenital malaria in women who delivered at the local hospitals of north-west Colombia, between June 2008 and April 2011. Methods A group of 129 parturient women was selected to explore the prevalence of gestational, placental and congenital malaria in a descriptive, prospective and transversal (prevalence) design. Diagnosis was based on the simultaneous application of two independent diagnostic tests: microscopy of thick blood smears and a polymerase chain reaction assay (PCR). Results The prevalence of gestational malaria (thick smear /PCR) was 9.1%/14.0%; placental malaria was 3.3%/16.5% and congenital malaria was absent. A history of gestational malaria during the current pregnancy was significantly associated with gestational malaria at delivery. Plasmodium vivax caused 65% of cases of gestational malaria, whereas P. falciparum caused most cases of placental malaria. Conclusions Gestational and placental malaria are a serious problem in the region, but the risk of congenital malaria is low. A history of malaria during pregnancy may be a practical indicator of infection at delivery. PMID:24053184

    This study aimed to investigate coagulation, fibrinolysis indicators, and malaria during pregnancy. Methods. A cross-sectional study was conducted at Medani, Sudan. Sociodemographic characteristics were gathered from each parturient woman (163) and malaria was investigated by blood film and placental histology. Protein C, protein S, antithrombin-III, tissue factor pathway inhibitor (TFPI), and plasminogen activator inhibitor-1 levels (PAI-1) were measured using ELISA. Results. One (0.6%), three (1.8), and 19 (11.7%) of the placentae showed active, chronic, and past infection on a histopathological examination, respectively, while 140 (85.9%) of them showed no signs of malaria infection. While the mean [SD] of the protein C, antithrombin-III, and TFPI was significantly lower, there was no significant difference in protein S and PAI-1 levels in women with placental malaria infection (n = 23) compared to those without placental malaria infection (140). In linear regression, placental malaria infection was associated with antithrombin-III. There was no association between placental malaria infections and protein C, protein S, TFPI, and PAI-1 levels. There was no association between hemoglobin, birth weight, and the investigated coagulation and fibrinolysis indicators. Conclusion. This study showed significantly lower levels of protein C, antithrombin-III, and TFPI in women with placental malaria infections. PMID:26295004

    The Great East Japan Earthquake occurred on March 11, 2011. The tsunami caused extensive damage to the Fukushima Daiichi Nuclear Power Plant, resulting in a level 7 nuclear accident. Among those affected by this combined disaster were many pregnant and parturient women. Sixteen months after the earthquake, we conducted a questionnaire survey on anxiety among 259 women who gave birth around the time of the earthquake in Miyagi Prefecture, one of the affected areas. Participants reported 12 categories of anxiety, including anxiety over radioactivity. This study aimed to determine anxiety over radioactivity among this specific population and to record measures for future study. Anxiety over radiation was classified into seven subcategories: food safety, outdoor safety, effects on the fetuses of pregnant women, effects on children, radiation exposure, economic problems, and distrust of information disclosed. This study confirmed that concrete types of anxiety over radiation were keenly felt by mothers who had experienced the disaster who were currently raising children. The findings suggest the need to provide accurate information to these mothers, who are otherwise inundated with miscellaneous confusing information. PMID:25363115

    OBJECTIVE To analyze the effects of acupressure at the SP6 point on labor duration and cesarean section rates in parturients served in a public maternity hospital. METHODS This controlled, randomized, double-blind, pragmatic clinical trial involved 156 participants with gestational age ≥ 37 weeks, cervical dilation ≥ 4 cm, and ≥ 2 contractions in 10 min. The women were randomly divided into an acupressure, placebo, or control group at a university hospital in an inland city in the state of Sao Paulo, Brazil, in 2013. Acupressure was applied to the SP6 point during contractions for 20 min. RESULTS The average labor duration was significantly different between the SP6 acupressure group [221.5 min (SD = 162.4)] versus placebo [397.9 min (SD = 265.6)] and versus control [381.9 min (SD = 358.3)] (p = 0.0047); however, the groups were similar regarding the cesarean section rates (p = 0.2526) and Apgar scores in the first minute (p = 0.9542) and the fifth minute (p = 0.7218) of life of the neonate. CONCLUSIONS The SP6 acupressure point proved to be a complementary measure to induce labor and may shorten the labor duration without causing adverse effects to the mother or the newborn. However, it did not affect the cesarean section rate. PMID:25741644

    Many medical and magical texts concerning childbirth and delivery are known from ancient Egypt. Most of them are spells, incantations, remedies and prescriptions for the woman in labour in order to accelerate the delivery or protect the unborn child and parturient. The medical and magical texts do not contain any descriptions of parturition itself, but there are some literary, astronomical and mythological texts, as well as a few incantations, which describe the biological act of childbirth and also miscarriage in more detail. Besides the textual sources, the decoration of temple walls and mammisis (birth houses), as well as illustrations on a birth brick provide an insight into the moment of delivery. In this paper, I focus on the "scientific"depiction of the biological act of childbirth, on how it is described in non-medical sources. Although the main sources are mythological-theological texts with numerous analogies, it is remarkable how many details they provide. They contain descriptions that would be expected in the context of medical sources. PMID:25481965

    It is generally accepted that progesterone is necessary to maintain gestation; however, the mechanisms that control the production of this steroid remain unknown. The corpus luteum has been assigned a central role in the maintenance of gestation based on its capacity to produce progesterone. A pseudopregnancy model was performed in a viviparous lizard, Barisia imbricata imbricata, to determine whether the absence of embryos would affect the pattern of progesterone production or the corpus luteum histology. Blood samples were obtained prior to ovulation and at 8, 16, and 24 weeks after ovulation (pseudopregnant and pregnant lizards), as well as one day after parturition (pregnant lizards) or 32 weeks after ovulation (pseudopregnant lizards). The corpus luteum was surgically removed one day after blood samples were obtained. Blood aliquots from nongravid females were obtained at similar timepoints. We found a significant reduction in plasma progesterone concentrations at 24 and 32 weeks post-ovulation in pseudopregnant lizards compared with those observed at similar times in intact pregnant lizards, whereas the progesterone levels in non-gestant lizards remained significantly lower than in either pseudopregnant or pregnant lizards. Moreover, we observed that the histological appearance of the corpus luteum from pseudogestational females (obtained 24 and 32 weeks post-ovulation) differed from the corpora lutea from lizards in late gestation and intact parturient lizards. These observations suggest that the conceptus participates in the regulation of progesterone production in late gestation and also in luteolysis control. PMID:24975848

    'Fetal programming' is a newly emerging field that is revealing astounding insights into the prenatal origins of adult disease, including metabolic, endocrine, and cardiovascular pathophysiology. In the present study, we tested the hypothesis that rat pups conceived, gestated and born at 2-g have significantly reduced birth weights and increased adult body weights as compared to 1-g controls. Offspring were produced by mating young adult male and female rats that were adapted to 2-g centrifugation. Female rats underwent conception, pregnancy and birth at 2-g. Newborn pups in the 2-g condition were removed from the centrifuge and fostered to non-manipulated, newly parturient dams maintained at 1 -g. Comparisons were made with 1-g stationary controls, also crossfostered at birth. As compared to 1-g controls, birth weights of pups gestated and born at 2-g were significantly reduced. Pup body weights were significantly reduced until Postnatal day (P) 12. Beginning on P63, body weights of 2-g-gestated offspring exceeded those of 1-g controls by 7-10%. Thus, prenatal rearing at 2-g restricts neonatal growth and increases adult body weight. Collectively, these data support the hypothesis that 2-g centrifugation alters the intrauterine milieu, thereby inducing persistent changes in adult phenotype.

    Background: Evidence based practice is an effective strategy to improve the quality of obstetric care. Identification of barriers to adaptation of evidence-based intrapartum care is necessary and crucial to deliver high quality care to parturient women. Objectives: The current study aimed to explore barriers to adaptation of evidence-based intrapartum care from the perspective of clinical groups that provide obstetric care in Iran. Materials and Methods: This descriptive exploratory qualitative research was conducted from 2013 to 2014 in fourteen state medical training centers in Iran. Participants were selected from midwives, specialists, and residents of obstetrics and gynecology, with a purposive sample and snowball method. Data were collected through face-to-face semi-structured in-depth interviews and analyzed according to conventional content analysis. Results: Data analysis identified twenty subcategories and four main categories. Main categories included barriers were related to laboring women, persons providing care, the organization environment and health system. Conclusions: The adoption of evidence based intrapartum care is a complex process. In this regard, identifying potential barriers is the first step to determine and apply effective strategies to encourage the compliance evidence based obstetric care and improves maternity care quality.

    The aim of this study was to compare some blood biochemical indicators in cows with displacement of abomasum (DA) which recovered or died after treatment. Examinations were performed on 60 multiparous cows with left (L) or right (R) displacement and on 15 healthy herdmates. Diagnosis was made by experienced practitioners on the basis of clinical examination. Surgical treatment was undertaken during the first 24 hours after diagnosis. Almost all animals (55 = 91.5%) became sick in the post parturient period (21 days p.p. on average) with the exception of 5 (8.3%) that became sick later. Blood samples were taken from each cow immediately before surgical procedure. Serum nonesterified fatty acid (NEFA), glucose (Glu), cholesterol (Chol), aspartate aminotransferase (AST), total bilirubin (Bil) and blood urea nitrogen (BUN) were measured. Sick animals were characterized by low mean values of Chol (< or = 2 mmol/l) and normal level of BUN (12-15 mg/dl), higher levels of NEFA (> 600 micromol/l) and Bil (> 22 micromol/l), higher activity of AST (> 100 U/l). Seven cows (11.67%) died after surgical correction and all others recovered. No significant differences in NEFA, Chol, AST, Bil and BUN levels were observed as dependent on the efficacy of treatment (survival, deaths). It was found that cows which died after surgical treatment were characterized by significant higher levels of glucose (5.05 mmol/l) compared to surviving cows (2.93 mmol/l). PMID:20169926

    Direct intervention in infant delivery by non-parturient individuals is a rare phenomenon in nonhuman primates. In contrast, birth assistance by other individuals, or the practice of midwifery, is universal among human societies and generally believed to be a behavior unique to our species. It has been proposed that the enlarged head of the human fetus and the relatively narrow birth canal constrained by bipedalism has made human parturition more difficult than in nonhuman primates, and these anatomic challenges have led to the rotation of the fetus in the birth canal and an occiput anterior (i.e., backward-facing) orientation of emergence. These characteristics have hindered the mother's ability to self-assist the delivery of the infant, therefore necessitating assistance by other individuals or midwives for successful birth. Here we report the first high-definition video recordings of birth intervention behavior in a wild nonhuman primate, the white-headed langur (Trachypithecus leucocephalus). We observed that while a primiparous female gave birth to an infant in an occiput posterior (i.e., forward-facing) orientation, a multiparous female intervened in the delivery by manually pulling the infant out of the birth canal and cared for it in the following hours. Our finding shows extensive social interactions throughout parturition, and presents an unequivocal case of non-maternal intervention with infant birth in a nonhuman primate. PMID:24859849

    The National Family Planning Programme of India, since its inception in 1951, has been able to successfully achieve significant reductions in maternal mortality and fertility. Over the past decade, the need for contraception has changed dramatically in India. Couples no longer desire sterilization, but prefer modern reversible long-term methods of contraception. The ideal time to discuss contraception is in the antenatal period when there is a good rapport between the doctor and the patient. The window period when the patient is admitted in the hospital during delivery can be used effectively to offer postpartum contraception. It has been found that the highest chance of unwanted pregnancy is in the first year after delivery, when women do not report to the doctor if this window period is missed. Postpartum intrauterine contraceptive devices are ideal for a country like India and it can be used to cover the unmet need of contraception if inserted immediately after delivery. There are two types of insertion: post placental, within 10 min of delivery of placenta and postpartum, within 48 h of delivery. Although there is a greater chance of expulsion in the postpartum insertions, it can be significantly reduced with proper training and user experience. Postpartum IUCD should be routinely offered to all patients delivering in institutions to provide complete care to a parturient and to achieve safe motherhood. PMID:26243985
