Clinical manifestations of valproic acid (VPA) toxicity can range from just mild confusion and drowsiness to serious encephalopathy, leading to depressed sensorium and even coma and death. The exact cause(s) of how VPA influences the integrity of brain function remains unknown. Nevertheless, several mechanisms have been postulated including a surge in the blood ammonia concentration. Valproic acid–induced hyperammonemic encephalopathy is a rare yet serious sequalae and that can lead to grave outcomes. We report a case of hyperammonemic encephalopathy with preserved liver function following a moderate VPA intoxication in a toddler, who was successfully managed conservatively. Additionally, we briefly discuss mechanistic basis of VPA toxicity and highlight some of the available potential therapies.

Sickle cell Anemia (SCA) is a common inherited haemoglobinopathy resulting from a single-point mutation on the β-globin subunit of hemoglobin. It is a chronic condition with multi-system involvement. Growth delay, osteopenia and hypogonadism are common endocrine dysfunctions with a lower frequency of impaired glucose tolerance. However, there is an association between SCA and diabetes mellitus (DM), though it is very rare. Certainly, there are only a few published reports worldwide outlined this uncommon combination. In this report, we will present the first Libyan case study of co-existence of the two diseases in a-16-month-old male toddler recording the youngest patient diagnosed with such a rare combination. The child, who was diagnosed earlier with SCA, brought with concerns of frequent changing nappies (polyuria) and excessive thirst (polydipsia) for 2 weeks that worsened recently. On admission, the toddler was distressed, lethargic and his lab parameters showed hyperglycemia, ketonuria, glycosuria and acidosis, a diagnosis of diabetic ketoacidosis (DKA) on the background of SCA therefore was made. Further observations are warranted to properly guide about the diagnosis and management of such rare cases.

Background A retropharyngeal abscess (RPA) is a deep neck infection that considers a medical emergency because of the possibility of serious complications including life-threatening upper airway obstruction, mediastinitis, and sepsis. Materials and Methods We present our experience in Benghazi Children's Hospital, describing the clinical presentations, diagnostic workup, management, and the outcome of four children presented during the time period between November 2017 and November 2021 as cases of RPA secondary to penetrating trauma to the posterior pharyngeal wall either due to ingestion of a foreign body or due to manipulation of tonsils by the traditional therapist. Results All cases presented with fever, poor feeding, and hyperextension of the neck. All were diagnosed by ultrasound and they needed surgical drainage of RPA, as they did not improve with medical treatment alone. Conclusion A high index of suspicion is necessary for the early diagnosis and treatment of RPA. Two of our cases were presented following the manipulation of tonsils by a traditional therapist, so we attempted to emphasize this life-threatening consequence after traditional therapy, as well as the unnecessary morbidity and mortality associated with this ongoing traditional treatment in our country.
