Objective To investigate the characteristics of memory impairment in patients with amnestic mild cognitive impairment (aMCI). Methods Thirty-five patients with aMCI and 35 healthy adults matched with age and education level were administered with a neuropsychological battery of tests including conception and perception implicit priming tasks (category exemplar, picture identification), as well as explicit memory tasks (immediate recall, delay recall, delay recognition ). Results Compared with healthy elders, patients with aMCI were impaired in the conception implicit priming task(t=-4.33, P<0.01), as well as in explicit memory (immediate recall, t=6.40, P<0.01;delay recall, t=9.29,P<0.01; delay recognition, t=7.65,P<0.01),but not in perception implicit priming task (t=-0.78, P>0.05).The conception implicit priming is positively correlated with verbal fluency (r=0.74,P<0.01). Conclusions The present results indicate that patients with aMCI are impaired in both explicit memory and conception implicit priming. The conception implicit priming impairment in aMCI may be related to their frontal lobe dysfunction.

Primary angiitis of the central nervous system (PACNS) is a rare vasculitis restricted to the central
nervous system without systemic involvement. Delay in diagnosis and treatment is common due to its
non-specific symptoms and lack of non-invasive diagnostic tests. Myelopathy can occur in PACNS,
during the clinical course of the illness, with or without cerebral symptoms. We describe here a 51
year-old ethnic Chinese woman who presented initially with paraparesis without cerebral symptoms.
The diagnosis of PACNS was eventually made from brain biopsy when she subsequently developed
cerebral involvement. Despite aggressive treatment, the patient developed progressive neurological
deterioration and died. This patient demonstrates the rare occurrence of myelopathy as the sole initial
presentation of PACNS.

OBJECTIVE:
To evaluate the detection of humen-lung-specific X protein (LUNX) gene in micrometastases of patients with non-small cell lung cancer.
METHODS:
The expression of LUNX gene in tumor tissue, lung and lymph nodes was detected by reverse transcriptase-polymerase chain reaction(RT-PCR) both in 43 non-small-cell lung cancer patients (the experimental group) and 15 lung benign patients (the control group). LUNX mRNA expression in clinic pathology,stage of cancer cell differentiation, clinic stage, age, sex, smoking history, and 4 lung cancer blood markers (CEA,CA125,NSE, and CYFRA211) were evaluated.
RESULTS:
The expression of LUNX gene was positive in the 2 groups. LUNX gene expression was positive in 33 of the 87 lymph nodes of the 43 patients in the experimental group (37.93%), and in 2 of the 26 lymph nodes in the control group (7.69%). The LUNX mRNA positive in the lymph nodes was closely related to the pathological type, cancer cell differentiation and clinic stage(r=0.660,0.500,0.460; P=0.011,0.017,0.022, all P<0.05), while not closely related to age, sex, smoking history and 4 lung cancer blood markers (CEA,CA125, NSE, and CYFRA211) (r=0.111, 0.135,0.083,0.354; P=0.739,0.714,0.773,0.125,all P>0.05).
CONCLUSION
The LUNX mRNA expression detected by RT-PCR is more sensitive than by traditional ways. The expression of LUNX gene mRNA in the lymph nodes is a valuable index for the detection of micrometastases in patients with non-small cell lung cancer.

Background:
and Purpose Myasthenia gravis (MG) is clinically heterogeneous and can be classified into subgroups according to the clinical presentation, antibody status, age at onset, and thymic abnormalities. This study aimed to determine the clinical characteristics and outcomes of generalized MG (GMG) patients based on these subgroups.
Methods:
Medical records of MG patients from 1976 to 2023 were reviewed retrospectively.Patients with pure ocular MG were excluded. Data on demographic, clinical characteristics, laboratory features, and outcomes were analyzed.
Results:
This study included 120 GMG patients. There was a slight preponderance of female patients over male patients (male:female ratio=1:1.3), with the age at onset exhibiting a bimodal distribution. Female patients peaked at a lower age (21–30 years) whereas male patients peaked at a higher age (61–70 years). Most (92%, 105 of 114) patients had positive anti-acetylcholine receptor antibodies. Five patients were also tested for anti-muscle-specific tyrosine kinase antibodies, with two showing positivity. Thymectomy was performed in 62 (52%) patients, of which 30 had thymoma, 16 had thymic hyperplasia, 7 had an involuted thymus, and 6 had a normal thymus. There were significantly more female patients (68% vs. 45%, p=0.011) with early-onset disease (<50 years old) and thymic hyperplasia (33% vs. 0%, p<0.025). Most (71%) of the patients had a good outcome based on the Myasthenia Gravis Foundation of America postintervention status. GMG patients with early-onset disease had a significantly better outcome than patients with a late onset in univariate (58% vs. 37%, p=0.041) and multivariate (odds ratio=4.68, 95% confidence interval=1.17–18.64, p=0.029) analyses.
Conclusions
Female patients with early-onset MG and thymic hyperplasia had significantly better outcomes, but only early-onset disease was independently associated with a good outcome. These findings are comparable with those of other studies.

Background:
and Purpose Multiple acyl-CoA dehydrogenase deficiency (MADD) is an inherited disorder of fatty acid oxidation that causes lipid storage myopathy (LSM). This is the first report on MADD that describes the phenotypic and genetic features of a Malaysian cohort.
Methods:
Among the >2,500 patients in a local muscle biopsy database, patients with LSM were identified and their genomic DNA were extracted from muscle samples and peripheral blood.All 13 exons of the electron-transfer flavoprotein dehydrogenase gene (ETFDH) were subsequently sequenced. Fifty controls were included to determine the prevalence of identified mutations in the normal population.
Results:
Fourteen (82%) of the 17 LSM patients had MADD with ETFDH mutations. Twelve (86%) were Chinese and two were Malay sisters. Other unrelated patients reported that they had no relevant family history. Nine (64%) were females. The median age at onset was 18.5 years (interquartile range=16–37 years). All 14 demonstrated proximal limb weakness, elevated serum creatine kinase levels, and myopathic changes in electromyography. Three patients experienced a metabolic crisis at their presentation. Sanger sequencing of ETFDH revealed nine different variants/mutations, one of which was novel: c.998A>G (p.Y333C) in exon 9. Notably, 12 (86%) patients, including the 2 Malay sisters, carried a common c.250G>A (p.A84T) variant, consistent with the hotspot mutation reported in southern China. All of the patients responded well to riboflavin therapy.
Conclusions
Most of our Malaysian cohort with LSM had late-onset, riboflavin-responsive MADD with ETFDH mutations, and they demonstrated phenotypic and genetic features similar to those of cases reported in southern China. Furthermore, we report a novel ETFDH mutation and possibly the first ever MADD patients of Malay descent.

INTRODUCTIONEnteric fever is a multisystemic infection which largely affects children. This study aimed to analyse the epidemiology, clinical presentation, treatment and outcome of paediatric enteric fever in Singapore.
MATERIALS AND METHODSA retrospective review of children diagnosed with enteric fever in a tertiary paediatric hospital in Singapore was conducted from January 2006 to January 2012. Patients with positive blood cultures for Salmonella typhi or paratyphi were identified from the microbiology laboratory information system. Data was extracted from their case records.
RESULTSOf 50 enteric fever cases, 86% were due to Salmonella typhi, with 16.3% being multidrug resistant (MDR) strains. Sixty-two percent of S. typhi isolates were of decreased ciprofloxacin susceptibility (DCS). Five cases were both MDR and DCS. The remaining 14% were Salmonella paratyphi A. There were only 3 indigenous cases. Ninety-four percent had travelled to typhoid-endemic countries, 70.2% to the Indian subcontinent and the rest to Indonesia and Malaysia. All patients infected with MDR strains had travelled to the Indian subcontinent. Anaemia was a significant finding in children with typhoid, as compared to paratyphoid fever (P = 0.04). Although all children were previously well, 14% suffered severe complications including shock, pericardial effusion and enterocolitis. None had typhoid vaccination prior to their travel to developing countries.
CONCLUSIONEnteric fever is largely an imported disease in Singapore and has contributed to significant morbidity in children. The use of typhoid vaccine, as well as education on food and water hygiene to children travelling to developing countries, needs to be emphasised.
