Abstract

Biallelic mutations in the SLC30A10 gene cause an inborn error of Mn metabolism characterized by hypermanganesemia, polycythemia, early-onset dystonia, and liver cirrhosis (HMDPC). To date, only 14 families from various ethnic groups have been reported. Here, we describe 10 patients from 7 unrelated Egyptian families with HMDPC. Markedly elevated blood Mn levels, the characteristic basal ganglia hyperintensity on T1-weighted images, and variable degrees of extrapyramidal manifestations with or without liver disease were cardinal features in all patients. Eight patients presented with striking early diseased onset (≤2 years). Unexpectedly, early hepatic involvement before the neurological regression was noted in 3 patients. Mutational analysis of SLC30A10 gene revealed 6 novel homozygous mutations (c.77T > C (p.Leu26Pro), c.90C > G (p.Tyr30*), c.119A > C (p.Asp40Ala), c.122_124delCCT (p.Ser41del), c.780_782delCAT (p.Iso260del) and c.957 + 1G > C). Treatment using 2,3 dimercaptosuccinic acid as a manganese chelating agent showed satisfactory results with improvement of biochemical markers, hepatic manifestations and relative amelioration of the neurological symptoms. Our findings present a large cohort of patients with HMDPC from same ethnic group. The majority of our patients showed severe and early presentation with clear phenotypic variability among sibship. Moreover, we extend the phenotypic and mutational spectrum and emphasize the importance of early diagnosis and treatment of this potentially fatal disorder.

Hypercalcemia is common in patients with advanced head and neck squamous cell carcinoma (HNSCC). In this study, hypercalcemia was detected in 46 (51%) of 90 eligible patients with HNSCC over 4 years. Compared with nonhypercalcemics, hypercalcemics were more likely to be referred to palliative care, while they were inpatients (P = 0.004). During the last 3 months of follow-up, hypercalcemic patients were more likely than nonhypercalcemics to be hospitalized for ≥ 14 days (P = 0.01) and to visit the emergency room more than once (P = 0.04). The median survival from the first hypercalcemic episode was 74 days (95% CI, 0.234). With data calculated from the date of referral to palliative care, hypercalcemics had a shorter survival than did nonhypercalcemics (43 vs 128 days, respectively; P = 0.046). Early detection and management of hypercalcemia in patients with HNSCC may improve the chance of preventing distressing symptoms and reducing unnecessary frequent emergency room visits and lengthy hospitalization.

Galal, N., H. Fouad, A. Saied, and M. Dabnon, Hyperammonemia in the pediatric emergency care setting., , 2010. Abstract

Hyperammonemia is encountered frequently in acutely ill children presenting for emergency care with altered levels of consciousness (ALOC). Ammonia production, metabolism, and excretion are affected by different variables. Hyperammonemia may be a transient state or may signify more grave etiologies as inborn errors of metabolism. Levels of ammonia are also affected by proper sampling technique, transport, and analysis.


To determine the level of ammonia in acutely ill children with ALOC, identify causes of hyperammonemia, and correlate levels with illness severity and morbidity.


Observational study.


Emergency department at Cairo University Specialized Paediatric Hospital.


Fifty cases of acutely ill pediatric patients with ALOC who presented to the emergency department were included in the study from 2008 through 2009. Emergency department patients (n = 20) with known diseases that may induce hyperammonemia were excluded. Patients were subjected to detailed history taking with emphasis on factors affecting ammonia levels and thorough clinical examination. A cohort group of age- and sex-matched children acted as a control group.


The measured blood ammonia level ranged between 13 and 265 μmol/L, with a mean level of 95 μmol/L. Sixty percent of the children with ALOC had ammonia levels of greater than 75 μmol/L, with levels greater than 200 μmol/L seen in 6% of the studied sample. The study demonstrated a highly significant statistical difference between children with ALOC and control groups.There was no correlation between blood ammonia level and age. Correlations of ammonia levels were also conducted in comparison with etiological diagnoses and laboratory parameters with no statistical significance.There was no statistical significance between ammonia level and duration of illness, Sequential Organ Failure Assessment score, or Glasgow Coma Scale score/Morray Scale score.


Clinicians should consider testing children with ALOC for hyperammonemia, provided that a clear understanding of its metabolism and factors controlling it are understood. Proper sampling must be ensured. Mild elevations of ammonia levels are fairly common, but exceedingly high levels should raise concern and may require further evaluation
