RATIONALE/OBJECTIVE

Hemifacial spasm (HFS) is painless, paroxysmal, repetitive twitching of the unilateral facial muscle initially starting with the orbicularis oculi progressing to mid and lower facial muscles. This condition can be disabling and affect quality of life. Microvascular decompression (MVD) offers t he m ost permanent treatment and outcomes are measured through cessation of spasm. There are currently no Filipino-translated questionnaires to measure the quality of life (QOL) of patients with HFS. This study translated and validated the HFS-7 questionnaire and used it to assess and compare the preoperative and postoperative QOL of patients with HFS following MVD.

METHODS

The HFS-7 questionnaire was translated to Tagalog using a “forward–backward” translation method by 2 independent linguists. The translated questionnaire was validated by 4 expert neurosurgeons and were sent to 27 HFS patients to retrospectively assess pre-op and post-op QOL.

RESULTS

Twenty out of 27 HFS patients answered the survey. Majority of HFS patients were middle-aged females. The Criterion Validity Index (CVI) showed a result of 1 which indicates good validity of the translated HFS-7. It has good reliability with Cronbach alpha score of 0.97. T-test comparing the pre-op and post op scores showed that there is a significant improvement in QOL of HFS patients after MVD.

CONCLUSION

In patients with HFS, MVD offers an improvement of postoperative versus preoperative quality of life measurements. The Tagalog-translated HFS-7 questionnaire is a valid and reliable objective tool in measuring this treatment outcome.

INTRODUCTION: Intraventricular hemorrhage (IVH) as an extension of spontaneous intracerebral hemorrhage is an independent predictor of mortality. The Clot Lysis: Evaluating Accelerated Resolution of IVH phase 3 (CLEAR III) trial is a randomized, double-blinded, placebocontrolled, multiregional trial recently conducted to determine whether external ventricular drainage (EVD) plus intraventricular recombinant tissue plasminogen activator (rtPA, alteplase) improved outcome, in comparison to EVD plus saline. This study is an application of the rationale and principles of management in CLEAR III trial and related literature. METHODS: There are five patients described in this case series. Report followed the PROCESS guidelines. RESULTS: 30-day mortality in this series is 2 out of 5 while actual allcause mortality is 4 out of 5. Modified Graeb scores and IVH scores of all subjects have decreased after the intervention. However, good functional status defined as modified Rankin scale (mRS) score of 0-3 has not been achieved with the intervention. Efficacy of completely resolving IVH and hydrocephalus has been achieved in 2 out of 5 which translated to a benefit of survival to one of the two. Shunt dependence has been avoided by the subjects except for the one with the caudate intracerebral hemorrhage. Complications related to the intervention have been noted and discussed CONCLUSION In this single-institution study, patients for which rtPA was used for intraventricular fibrinolysis of IVH clot in addition to EVD as surgical treatment for hydrocephalus resulted to a 30-day survival of 3 out of 5 in this series, while actual survival is 1 out of 5. The intervention was efficacious in decreasing the Modified Graeb scores and IVH scores of all study subjects at end of treatment. Functional status of mRS 5 is the highest score achieved among survivors.

Vasospasm has been known to cause permanent morbidity in 40-70% of survivors who suffered from subarachnoid hemorrhage (SAH). Early recognition of vasospasm is the key to better outcome of SAH. Cerebral angiography is expensive and impractical as a monitoring tool. Transcranial Doppler is operator dependent, and not readily available. The objective of this study is to devise a non invasive tool to screen for cerebral vasospasm following SAH. The proposed vasospasm score was based on clinical and cranial CT scan features. The features are hypertension, admission World Federation of Neurosurgeons Score (WFNS), amount of blood in the cisterns and subarachnoid space, intraventricular hemorrhage and hydrocephalus. Thirty six patients with aneurismal SAH were assessed retrospectively and correlated with the angiogram for vasospasm. The patients’ vasospasm score and their corresponding sensitivity and specificity were: 1 (100%, 0%), 2 (100%, 8%), 3 (100%, 8%), 4 (100%, 8%), 5 (91%, 46%), 6 (74%, 85%), 7 (48%, 85%), 8 (26%, 23%), 9 (3%, 100%), 10 (4%, 100%). A receiver operator characteristic curve was constructed that yielded a cut-off score of 6. The score of 6 was a good trade-off between sensitivity (74%) and specificity (85%). A clinical vasospasm score was proposed to screen for vasospasm after SAH. A score of 4 to 6 was found to correlate with angiographic vasospasm. Prospective study is required to validate the scoring system.
