Acute subdural hematoma: Outcome and outcome prediction

Patients with traumatic acute subdural hematoma were studied to determine the factors influencing outcome.Between January 1986 and August 1995, we collected 113 patients who underwent craniotomy for traumatic acute subdural hematoma. The relationship between initial clinical signs and the outcome 3 months after admission was studied retrospectively.Functional recovery was achieved in 38% of patients and the mortality was 60%. 91% of patients with a high Glasgow Coma Scale (GCS) score (9–15) and 23% of patients with a low GCS score (3–8) achieved functional recovery. All of 14 patients with a GCS score of 3 died. The mortality of patients with GCS scores of 4 and 5 was 95% to 75%, respectively. Patients over 61 years old had a mortality of 73% compared to 64% mortality for those aged 21–40 years. 97% of patients with bilateral unreactive pupil and 81% of patients with unilateral unreactive pupil died. The mortality rates of associated intracranial lesions were 91% in intracerebral hematoma, 87% in subarachnoid hemorrhage, 75% in contusion.Time from injury to surgical evacuation and type of surgical intervention did not affect mortality. Age and associated intracranial lesions were related to outcome. Severity of injury and pupillary response were the most important factors for predicting outcome.

Isolated sphenoid sinus abscess: clinical and radiological failure in preoperative diagnosis. Case report and review of the literature

BACKGROUND: Isolated sphenoid sinusitis and abscess formation is a rare entity, which can lead to misdiagnosed or improperly treated patients and an unfavorable outcome. Invasion of the skull base and cavernous sinus usually causes cranial nerve palsies, suggesting a neoplasm at the initial presentation. CASE DESCRIPTION: A case of isolated abscess in the sphenoid sinus is reported. The complete destruction of the clivus and its unexceptional radiological data, in addition to the absence of clinical and laboratory evidence of infection, led us to misdiagnose a possible clival chordoma during preoperative evaluation. The patient underwent an endonasal-transsphenoidal procedure for diagnosis and surgical removal. Surgical drainage and prolonged antimicrobial treatment resulted in complete clinical recovery. CONCLUSION: Its close proximity to vital structures and slender bony structures may allow the infection to disseminate, with serious neurological complications. On the other hand, the variable clinical presentations and radiological data usually cause delayed or missed diagnosis in these cases. This emphasizes the importance of documentation of this unusual entity and its radiological manifestations.     

Novel bis-crown ethers and their sodium complexes as antimicrobial agent: synthesis and spectroscopic characterizations

A series of new compounds containing formyl and imine group were synthesized. New formyl-substituted compounds were prepared by the reaction of 1,2-bis(bromomethyl)benzene with benzaldehyde derivatives in the presence of NaOH. New bis-crown ether imine compounds were prepared by the condensation of corresponding aldehydes with 4′-aminobenzo-15-crown-5. Sodium complexes of the bis-crown ethers form crystalline 2:1 (Na⁺:ligand) stoichiometries were also been synthesized. The prepared compounds were structurally confirmed by analytical and spectral data and evaluated for their antibacterial and antifungal activities. The results show that the antibacterial activity of compounds including o-methoxy group was significantly higher against S. epidermis compared to the other studied antimicrobial group.
