RESUMO
Guillain Barre syndrome (GBS) following Varicella zoster is a rare presentation and has only been reported in a few cases around the world. Of the reported cases, the type of GBS is not specified in the majority, and where specified is of the acute inflammatory demyelinating polyradiculoneuropathy (AIDP) type. We report a case of acute motor axonal neuropathy (AMAN) type GBS following herpes zoster in a 27-year-old male who presented with bilateral lower limb weakness and left sided lower motor neuron type facial nerve palsy a week after herpes zoster infection.

BACKGROUND: Half of Guillain-Barré syndrome (GBS) present elevated cerebrospinal fluid (CSF) protein levels within 1 week since symptom onset and 80% within 2 weeks. Our objective was to determine the clinical and prognostic implication of albuminocytological dissociation in early GBS. METHODS: An ambispective cohort study was conducted. Good outcome was considered if the patient was able to walk unaided (Guillain-Barré disability score [GDS] ≤ 2 points) at 3-month follow-up. Patients were classified into two groups: with and without albuminocytological dissociation; we compared clinical and paraclinic characteristics between the groups. We analyzed clinical and electrophysiological factors related to presenting early dissociation through a multivariate model. RESULTS: We included 240 patients who fulfilled Asbury criteria for GBS. On further selection, only 94 patients fulfilled inclusion. Mean age was 45.94 ± 17.1 years and 67% were male. Median time from symptom onset to admission was 5 days (IQR 3-6). Regarding albuminocytological dissociation and electrophysiological variants, we found a significant difference: acute inflammatory demyelinating polyneuropathy (AIDP) [60.6% vs 26.2%, p = 0.002], acute motor axonal neuropathy (AMAN) [21.2% vs 49.1%, p = 0.009] and acute motor sensory axonal neuropathy (AMSAN) [12.1% vs 1.6%, p = 0.05]. We did not observe significant differences in recovery of independent walking in short term between both groups. The presence of conduction block in any variant (OR 3.21, 95% CI 1.12-9.16, p = 0.02) and absence of sural registration (OR 5.69, 95% CI 1.48-21.83, p = 0.011) were independent factors related to early dissociation. CONCLUSIONS: Early dissociation (<7 days) is not associated with any particular clinical feature or unfavorable outcome. It is more common to see in AIDP rather than axonal variants.

BACKGROUND AND PURPOSE: Intravenous immunoglobulin (IVIg) is recommended in Guillain-Barré syndrome (GBS), but its efficacy may vary in different subtypes. We report the outcomes of patients with GBS following IVIg treatment compared to the natural course (NC). We also compare the effect of IVIg treatment in different subtypes of GBS. METHODS: From a cohort of 528 GBS subjects, we have extracted 189 patients who received IVIg and compared their outcomes with 199 age- and peak disability-matched patients who did not receive IVIg, plasmapheresis, or corticosteroid. Disability was assessed using the 0-6 Guillain-Barré Syndrome Disability Scale (GBSDS). Clinical and neurophysiological subtypes were recorded. The primary outcome was functional disability at 6 months, which was categorized as complete (GBSDS ≤ 1), partial (GBSDS 2-3), or poor (GBSDS > 3). The secondary outcomes were in-hospital death, duration of hospitalization, and mechanical ventilation. RESULTS: In-hospital death (2.6% vs. 2%, p = 0.74) and 3-month poor recovery (20.7% vs. 18%) were similar in the IVIg and NC groups. At 6 months, however, a lesser proportion of patients in the IVIg group had poor recovery (2.2% vs. 8.3%, p = 0.026). The outcomes of IVIg and NC were compared in 72 acute motor axonal neuropathy (AMAN) and 256 acute inflammatory demyelinating polyradiculoneuropathy (AIDP) patients. IVIg therapy did not alter the outcome in AMAN but resulted in a lesser proportion of poor recovery at 6 months in AIDP (0.8% vs. 6.6%, p = 0.03). CONCLUSIONS: IVIg is beneficial in AIDP variants of GBS but not in the AMAN subtype. A customized treatment may be cost-effective until a randomized controlled trial is conducted in AMAN.

A newly introduced term, "axonal conduction block," brought a confusion in the electrodiagnostic diagnosis of Guillain-Barrè syndrome (GBS). I am proposing the term "nodal conduction block" for "axonal conduction block." This unifying concept of nodal conduction block will accommodate both the traditional concept of demyelination as well as the new concept of nodopathy in the "axonal form of GBS,", making the practice of electrodiagnosis much easier.

BACKGROUND: It is not well defined whether Guillain-Barré syndrome (GBS) patients with elevated serum creatine kinase (CK) levels have characteristic clinical features and are related to the subgroups of GBS. METHODS: We retrospectively studied 51 consecutive patients with GBS, who visited our hospital, and compared clinical, laboratory and electrophysiological findings between patients with and without elevated CK levels. RESULTS: Of 51 patients, 14 patients (27%) showed an elevation of serum CK levels. When compared with patients with the normal CK levels, the ratios of male, antecedent infections, and anti-GM1 antibody positivity were significantly higher in patients with elevated CK levels. The ratios of hypoesthesia, cranial nerve involvement, and urinary retention were significantly less in patients with elevated CK levels. There were no significant differences in disability at peak between two groups. In the electrophysiological examination, sensory nerve abnormalities were not observed. Although some patients with elevated CK levels showed prolongation of distal motor latencies (DMLs) and increase of durations in the initial examination, development of the prolongation of DMLs and increase of durations was not observed in the follow-up examinations. The findings were consistent with acute motor axonal neuropathy (AMAN) with reversible conduction failure (RCF) but not acute inflammatory demyelinating polyneuropathy (AIDP). CONCLUSIONS: The results suggest that the GBS patients with elevated CK levels represent not a group of AIDP but a group of AMAN with axonal degeneration or RCF even though the initial electrophysiological examination shows AIDP pattern.

Guillain-Barré syndrome (GBS) is an acute immune-mediated polyradiculoneuropathy with a worldwide incidence of 0.81-1.89 per 100 000 person-years. In Europe and North America only 5% of patients with GBS have axonal subtypes, which in South America and Asia account for 30%-47% of cases. The aim of our study is to assess the annual incidence and clinical features of GBS in La Spezia area in Italy. A retrospective (from 1 January 2003 to 31 December 2011) followed by a prospective (from 1 January 2012 to 31 December 2015) analysis was carried out on patients admitted to La Spezia hospital who fulfilled the GBS diagnostic criteria. A total of 86 patients (58 men), mean age of 62.7 years (range 21-90), were included. The mean annual incidence rate was 3/100 000 (range: 0.9/100 000-5.37/100 000) significantly higher than the European incidence (P < 0.001). Forty-seven percent were classified as acute inflammatory demyelinating polyradiculoneuropathy (AIDP), 35% as acute motor and motor-sensory axonal neuropathy (AMAN-AMSAN), 13% as variant forms, and 5% were not defined. AIDP was most common in "Golfo dei Poeti" (50%) and "Val di Magra" (63.2%), whereas AMAN/AMSAN prevailed in "Val di Vara" (63.6%) and "Riviera Spezzina" (62.5%) (P = 0.024). In La Spezia area GBS incidence (especially the AMAN subtype) is significantly higher than the incidence reported in Europe. AIDP predominates in the eastern area whereas AMAN/AMSAN in the western, with a significantly different incidence rate (P = 0.003). Prospective studies to assess possible predisposing environmental factors are needed.

INTRODUCTION: There have been few reports on subtypes of Guillain-Barré syndrome (GBS) in children. We compared clinical and laboratory findings of acute inflammatory demyelinating polyradiculoneuropathy (AIDP) and acute motor axonal neuropathy (AMAN). METHODS: One hundred forty children with GBS were included. Based on nerve conduction study (NCS) findings, patients were subclassified as AIDP, AMAN, acute motor sensory axonal neuropathy (AMSAN), and equivocal. RESULTS: Clinically, 72.1% of patients had pure motor, 24.3% motor sensory, and 3.4% Miller Fisher syndrome. Based on NCS, 67.8% of patients had AIDP, 23.6% had AMAN, and 4.3% had AMSAN. By 3 months, 2.1% patients had died, 47.1% had complete recovery, and 24.3% had poor recovery (wheelchair-bound). Children with AMAN had more frequent lower limb weakness (P = 0.02) and a lower probability of complete recovery (P = 0.01) at 3 months than children with AIDP (56% vs. 30%). DISCUSSION: AIDP is the most common GBS subtype in children. It is characterized by better recovery at 3 months when compared with AMAN. Muscle Nerve 57: 761-765, 2018.

INTRODUCTION: The frequency of axonal Guillain-Barré syndrome (GBS) varies among countries. Previous studies supporting the high frequency of axonal GBS in South America have been carried out with pediatric populations. We seek to determine the frequency of axonal GBS in both children and adults in South America. METHODS: This is a retrospective cohort analysis of patients who were diagnosed with GBS between January 2006 and December 2013 in a neurological center in Buenos Aires, Argentina. Adults and children with a diagnosis of GBS were included and classified by applying Ho and colleagues' criteria1 for axonal GBS. RESULTS: The study included 105 patients with GBS. Among 58 adults, only 5 individuals were classified as axonal GBS compared with 16 of 47 children. The frequency of axonal GBS was significantly higher in children than in adults (34% vs. 8.6%, P = 0.0001). DISCUSSION: As shown in a cohort of South American patients, age may impact the frequency of axonal GBS. Muscle Nerve 56: 1311-1313, 2017.

There is a paucity of large studies evaluating the subtypes of Guillain-Barré syndrome (GBS) and their outcome from Southeast Asia. We report cliniconeurophysiological subtypes of GBS and their correlation with triggering events and 3-month outcome from northern India. Three hundred and twenty eight consecutive patients with GBS were clinically evaluated, including their triggers, severity, autonomic involvement, cranial nerve palsy, and respiratory paralysis. Nerve conduction study (NCS) was repeated at 3 weeks if the initial study was normal. They were categorized into acute inflammatory demyelinating polyradiculoneuropathy (AIDP), acute motor axonal neuropathy (AMAN), acute motor sensory axonal neuropathy (AMSAN), inexcitable motor nerve, and equivocal. Clinically, 204 (62.2%) patients had pure motor, 106 (32.3%) motor sensory, 16 (4.9%) Miller Fisher syndrome, and 2 (0.6%) pure sensory GBS. Based on NCS, 242 (73.8%) had AIDP, 44 (13.4%) AMAN, 15 (4.6%) AMSAN, 8 (2.4%) inexcitable motor nerves, and 27 (8.2%) equivocal GBS. AIDP patients were older, more common in summer, had lesser peak disability, and better outcome compared to those with AMAN. Eleven (3.4%) patients died and 48 (14.6%) had poor outcome at 3 months. The poor outcome was related to severity, dysautonomia, and inexcitable motor nerves. AIDP is the commonest variant of GBS in our study and has better outcome compared to AMAN.

Introduction: Diabetes mellitus (DM) is a serious non-communicable disease (NCD) that represents a major health and development challenge of the 21st century. Ethiopia is the leading country among the top five high-burden African countries for the number of people with diabetes. To address problems within the population, it is important to assess the prevalence of diabetes and identify the risk factors associated with its diagnosis. Objective: The study aims to determine the prevalence of diabetes and identify its associated factors among office workers of Mizan-Aman Town administration and Bench Sheko Zone Sector Office. Methods: A sector office-based cross-sectional study was conducted on 559 randomly selected employees of Mizan Aman Town Administration and Zonal Office from June 5 to June 30, 2022. Fasting plasma glucose was tested, and the result ≥126 mg/dL was used to diagnose DM. Data were entered using Epi Data version 4.0.2 and exported to the Statistical Package for the Social Sciences (SPSS version 26) for analysis. Bivariate analyses were included in the multivariable model with p <0.25. Adjusted odds ratios (AOR) with a confidence interval (CI) of 95% are reported, with a significance level of p < 0.05. Results: The overall prevalence of Diabetes was 9.4% with 95%CI(7.1,12.1)). Among the participants,60.8% were men, 58.2% of workers were aged 40 years or older, and the mean age was 39.7 ± 9.9 years. Having hypertension (AOR 3.85, 95% CI (1.7,7.4), family history of diabetes (AOR 4.5, 95% CI (1.2, 15.8), physical inactivity defined as failure to participate in moderate intensity activities at work, sitting ≥180 minutes per day (AOR = 3.57, 95% CI (1.1, 11.0)) and having central obesity AOR: 3.25, 95% CI (1.5, 6.7) independently associated with higher odds of DM. However, those having good knowledge of DM (AOR=0.26, 95% CI: (0.10, 0.6)) and consuming fruits and vegetables greater than five servings per week (AOR=0.32 95% CI (0.1, 0.7)) predicted lower odds of DM. Conclusions and Recommendations: The prevalence of DM among office workers was high and is associated with lifestyle, family history, dietary practices, and knowledge about DM. Therefore, arranging regular screening programs at the workplace and promotion of healthy diet, exercise, and awareness creation are needed to lower the prevalence.
RESUMO
Background: Traffic accidents on the road is an accident is a terrible accident that causes death, injury, and property damage. However, limited studies were addressed to investigate the prevalence of traffic accidents on the road and the contributing factors among drivers that help in developing strategies to cop-up the incidence within the research domain in Ethiopia, particularly in the study area. Objective: This study aimed to assess the prevalence of road traffic accidents and the contributing factors among drivers of public transportation in Mizan Aman town, Ethiopia. Methods: A community-based cross-sectional survey was employed among 376 drivers of public transportation. Every research subject was selected by using a simple random sampling technique. Semi-structured and open-ended questionnaires which comprised demographic characteristics, risky personal behaviors and lifestyles, driver's factors, vehicle condition, and environmental conditions were used to gather data. And then after, data was collected through interviewer-administered using KoBo Collect tools. Completed data were edited and cleaned in the Kobo collect toolbox and then exported for additional analysis to a statistical tool for social science statistics version 26. The descriptive statistics were displayed as figures, tables, and texts. Binary logistic regression was analyzed to identify the contributing factors. Statistically significant was decided with a p-value of ≤ 0.05. Results: The results showed that the prevalence of road traffic accidents among drivers of public transportation in Mizan Aman town was 17%. The study identified factors influencing traffic accidents on the roads including marital status (being single), employee condition (permanent), monthly income (1001-2500 Ethiopia Birr), alcohol use, vehicle maintenance (not), road type (non-asphalt), and weather conditions (being windy). Conclusion: The overall prevalence of road traffic accidents among drivers of public transportation in Mizan Aman town was relatively low. Despite this, sociodemographic characteristics, driver factors, vehicle conditions, and environmental conditions [road type and weather conditions] were the predicting factors of traffic accidents in town. Therefore, reduction strategies should be the highest priority duty for concerned bodies like Mizan Aman town road and transport office, Bench Sheko zone transport and logistics office, and Southwest Ethiopia People Regional State (SWEPRS) transport bureau in the study area.

The usability gaps between climate information producers and users have always been an issue in climate services. This study aims to tackle the gap for rice farmers in Bangladesh by exploring the potential value of tailored agronomic monsoon onset definitions. Summer aman rice is primarily cultivated under rainfed conditions, and farmers rely largely on monsoon rainfall and its onset for crop establishment. However, farmers' perception of the arrival of sufficient rains does not necessarily coincide with meteorological definitions of monsoon onset. Therefore, localized agronomic definitions of monsoon onset need to be developed and evaluated to advance in the targeted actionable climate forecast. We analyzed historical daily rainfall from four locations across a north-south gradient in Bangladesh and defined dynamic definitions of monsoon onset based on a set of local parameters. The agronomic onset definition was evaluated in terms of attainable yields simulated by a rice simulation model compared to results obtained using conventional meteorological onset parameters defined by the amount of rainfall received and static onset dates. Our results show that average simulated yields increase up to 7 - 9% and probabilities of getting lower yields are reduced when the year-to-year varying dynamic onset is used over the two drier locations under fully rainfed conditions. It is mainly due to earlier transplanting dates, avoiding the impact of drought experienced with early monsoon demise. However, no yield increases are observed over the two wetter locations. This study shows the potential benefits of generating "localized and translated" climate predictions.

RESUMO
This report details the case of a female patient who was admitted with severe dengue, which was further complicated by bilateral pneumonia and multiple organ involvement. The patient also developed quadriparesis, a neurological complication, and had a recent history of vaccination with the COVISHIELD COVID-19 vaccine. A nerve conduction study later determined the condition to be acute motor axonal neuropathy, a variant of Guillain-Barré syndrome (GBS). While neurological complications, such as GBS, are rare in dengue cases, they can significantly affect patient outcomes. Treatment with intravenous immunoglobulin (IVIG) has proven to be an effective disease-modifying therapy for GBS. IVIG therapy is recognized for its anti-inflammatory and immunomodulatory effects, making it beneficial in certain autoimmune conditions, including those involving the nervous system. However, its use in severe infections or sepsis remains controversial. In this case, IVIG therapy was administered alongside broad-spectrum antibiotics. The patient's favorable response to IVIG therapy and subsequent clinical improvement highlight the importance of early recognition and targeted intervention for neurological complications in dengue cases.
RESUMO
A prevalent clinical scenario is provided in this case study, in which a 22-year-old lady with a five-year history of lupus nephritis with acute motor axonal neuropathy presents for therapy. The patient received immunomodulator medication and steroids to control her symptoms to keep up with her everyday life despite the absence of comorbidities such as hypertension, diabetes, and hypothyroidism. No laboratory measures were changed, including hemoglobin, serum creatinine, or thyroid function. Examining the nervous system indicated a potentially harmful consequence, underscoring the significance of prompt investigation and treatment. This research highlighted the importance of attention in cases with lupus nephritis, showing how early medical care can prevent serious neurological problems and contribute to the patient's general well-being.
RESUMO
Guillain-Barré syndrome is a polyneuropathy that can be caused by an autoimmune condition or a bacterial infection. In typical GBS cases, there is hypo- or areflexia, symmetrical limb weakness that worsens within four weeks of the symptoms. The facial nerve is involved in this situation, which results in weak facial muscles, which, in turn, affect facial emotions and movements. In this case study, a 21-year-old athlete who suffered from unexpected weakness that resulted in quadriplegia had goal-oriented physical therapy treatment designed for the patient, who recovered quickly. This case study aims to emphasize how goal-oriented physical therapy treatment can help patients recover quickly.
RESUMO
Background: To improve pregnancy outcomes, a pregnant mother living with HIV/AIDS requires a high level of social and emotional support. However, women from low-income countries were subjected to low social support status despite adequate counseling and health messages to increase their social support. Therefore, this study aimed to investigate the predictors of the perceived poor social support status among pregnant women attending ART clinics in Southwest Ethiopia. Methods: A hospital-based cross-sectional study with consecutive sampling was conducted to enroll 265 pregnant women on antiretroviral therapy (ART) from December 1 to 30, 2021. The data were collected using an interviewer-administered questionnaire. Epidata was used for data entry and analyzed after it was exported to a statistical package for the social sciences. Binary logistic regression was used and the level of significance was declared at P-value <0.05 using Adjusted odds ratio at 95% CI after candidate variables were identified in binary logistic regression at a P-value of <0.25. Results: Finding from the study figured out that low level of poor social support is found to be 47.2%. Study revealed that income level[AOR = 5.1 95% CI [1.9,13.6]], disclosure status[AOR: 1.9 95% CI [1.1,3.3]], unwanted pregnancy [AOR = 2.3 CI; [ 1.4,3.9]], and low adherence level[AOR: 2.1 95% CI [1.1,3.1]] were strong predictors. Conclusion: This study identified high levels of poor social support. Increasing access to information education and communications focusing on stigma, disclosure & refresher training that boosts the counseling skills of health care providers to enhance adherence level is strongly recommended.
RESUMO
Various reports of neurological manifestations of SARS-COV-2 infection after the virus outbreak are available, including anosmia, seizures, acute flaccid myelitis, Guillain-Barré syndrome (GBS), and encephalitis. Most of the literature has focused on the respiratory manifestation of SARS-CoV-2 infection in adults, but recent evidence showed that it is not confined to the respiratory tract. This report is about a rare variant of GBS acute motor axonal neuropathy (AMAN) in a child due to COVID-19 infection An 11 years old boy was referred to the hospital with a history of three-day lasting mild fever, and gastroenteritis, two weeks before starting symptoms. He was presented with progressive ascending weakness, paresthesia, and areflexia in four limbs four days ago. Nasopharyngeal swab polymerase chain reaction (PCR) was positive for SARS-CoV-2. The electrodiagnostic finding was compatible with acute generalized axonal motor neuropathy, and imaging revealed thoracolumbar syrinx and nerve root enhancement in lumbosacral MRI. Other lab tests were normal. GBS and its variant are one of the manifestations of SARS-CoV-2 in children. Children with an unexplained neurological process should be tested for SARS-CoV-2.
RESUMO
Objective: One or more inexcitable motor (IM) nerves are common during electrodiagnostic (EDx) study in Guillain-Barré syndrome (GBS). This study assessed the dose-effect relationship of IM nerves on outcome in patients with acute inflammatory demyelinating polyneuropathy (AIDP) and acute motor and/or sensory axonal neuropathy (AMAN and AMSAN). Materials and Methods: Eighty-eight GBS patients admitted during May 2018-June 2023 underwent detailed clinical evaluation and EDx study. Admission and follow-up disability were assessed on a 0-10 Clinical Grading Scale (CGS). Outcome was recovery at 6 months, defined as good (CGS <3) and poor (CGS ≥3). Binary multivariate logistic regression with backward elimination was used to calculate independent predictors of outcome. Results: Proportion of patients with complete recovery decreased significantly with increasing numbers of IM nerves (P < 0.01). Seventy-six patients were followed for 6 months. Among patients with IM nerves (n = 28), complete recovery was similar between AIDP and axonal GBS (70% vs. 50%, respectively; P = 0.40). However, in patients with recordable compound muscle action potentials (CMAPs) in all the motor nerves (n = 26), axonal GBS had significantly poor recovery compared to AIDP (75% vs. 9.1%; P = 0.01). Among patients receiving intravenous immunoglobulin (IVIg; n = 42), poor recovery was seen in 53.6% with IM nerves compared to 35.7% without (P = 0.28), while it was 37.5% versus 5.6% (P = 0.04), respectively, in those who did not receive IVIg (n = 34). However, only admission disability (odds ratio [OR] 0.88, 95% confidence interval [CI] 0.81-0.97; P = 0.007) was found to be an independent predictor of outcome. Conclusion: Although increasing numbers of IM nerves were associated with poor outcome on univariate analysis, they did not predict 6 months' outcome independently. Outcome did not differ between axonal GBS and AIDP among those with IM nerves. IVIg improved outcome in patients with IM nerves.
RESUMO
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019, and is the infectious agent that caused the coronavirus disease 2019 (COVID-19) pandemic. Although respiratory and gastrointestinal manifestations of SARS-CoV-2 are well defined, the spectrum of neurological involvement is less defined. The classic type of Guillain-Barré syndrome (GBS) progresses over days to weeks and has a monophasic course. Areflexia/hyporeflexia and ascending and symmetrical paralysis are observed clinically in patients. It is an autoimmune process that typically leads to the destruction of myelin after infection. There have been numerous reports of adult patients with the coexistence of GBS disease and active COVID-19 illness, but this number is lacking for children. In this study, we present a literature review of the etiological correlation between SARS-CoV-2 and GBS and describe the cases of two pediatric patients with acute monophasic Guillain-Barré syndrome (GBS) during active COVID-19 infection.

BACKGROUND: Guillain-Barré Syndrome (GBS) is the most common cause of acute, usually post-infectious, peripheral neuropathy resulting in a symmetrical, ascending paralysis. We evaluated the clinical and neurophysiological features, treatment, and outcomes of patients with GBS in our center. METHODS: A retrospective chart review on patients with GBS admitted to King Abdulaziz Medical City, Riyadh, Saudi Arabia, from January 2011 to December 2020. Data were analyzed using JMP statistical software version 15 pro. RESULTS: A total of 86 patients who met the criteria were included, 55 (64%) were males, with a mean age of 49.5+/-17.5 years. Antecedent infection was reported in 53 (61.6%), 51 (62.2%) presented within one week of symptoms onset. Ascending weakness was seen in 55 (70.5%), while 70 (81.4%) had areflexia. Acute motor axonal neuropathy (AMAN) was the commonest electrophysiological type of GBS in 41 (51.9%) patients. Albuminocytologic dissociation was seen in 48 (57%) who had lumbar puncture. Nearly half, 41 (47.7%) were admitted to the intensive care unit (ICU). Seventy (81.3%) were treated with intravenous immunoglobulin. There was no significant difference in the clinical presentation, management, ICU requirement, and discharge disposition between males and females. Females were more likely to have a higher disability at discharge (p=0.01). Patients younger than 60 years were more likely to require ICU admission (p=<0.01). CONCLUSION: Our patients with GBS were slightly older than previously reported from the region. AMAN was the commonest type of GBS. Younger patients were more likely to need ICU admission, whereas females were more likely to have a more severe disability.
