Clinical and Molecular Hepatology 2023;29(4):909-923
Emergence of multi-targeted kinase inhibitors (MTIs) and immune checkpoint inhibitors (ICI) have changed the landscape of management in hepatocellular carcinoma (HCC). Combination therapy involving ICI has superseded sorafenib as the first-line treatment option for advanced HCC due to their superior response rates and survival benefits based on recently published phase III trials. However, the role of first-line lenvatinib remains uncertain as no prospective trials have compared its efficacy with ICI in advanced HCC. Several retrospective studies have shown that first-line lenvatinib may not be inferior to ICI combination. Indeed, a growing body of evidence suggests that ICI treatment is associated with inferior treatment outcome in non-viral HCC patients, questioning the supremacy of ICI treatment in all patients and rendering first-line lenvatinib as a potential preferred treatment option. Furthermore, in high-burden intermediate-stage HCC, accumulating evidence supports first-line lenvatinib, or in combination with transarterial chemoembolization (TACE), as a preferred treatment option over TACE alone. In this Review, we describe the latest evidence surrounding the evolving role of first-line lenvatinib in HCC.

An open lung biopsy was performed in 12 children with diffuse parenchymal lung disease. A definitive histopathological diagnosis was obtained from all procedures but determined treatment options in only 10 children (83%). Three (25%) children were ventilated for respiratory failure prior to the procedure. Four (44%) of the other 9 children required ventilatory support after the procedure. Three (25%) children developed post-op pneumothorax that resolved fully with chest tube drainage. There were no deaths as a direct result of the procedure. Open lung biopsy is useful in providing a definitive diagnosis in children with diffuse parenchymal lung disease and determining treatment in the majority of cases. The procedure was well-tolerated with minimal complications.

OBJECTIVES: To determine the effect of age, ex and body index on selected static tests of balance and to generate referance normtive data among the different population groups.
METHODS: In this cross-sectional study, 100 asymptomatic normal adult Filipino volunteers, aged 20 to 69 years were tasked to perform selected static balance tests. These tests included classic Romberg (CR), Romberg with Jendrassik (RJ) maneuver, tandem Romberg (TR), standing on foam with feet apart (SOFFA), standing on foam with feet together (SOFFT) and standing on one leg (SOL). All tests were done with eyes opened (EO) followed by eyes closed (EC) for 30 seconds each. Volunteers were grouped into age groups by decades, normative values were obtained and effects of age, sex and body mass index, if any, on performance of the various tests were determined.
RESULTS: All volunteers were able to do the CR and RJ maneuver for 30 seconds. All were able to perform for 30 seconds the TREO, SOFFA EO and SOFFT EO procedures. Some volunteers were unable to complete the TREC, SOFFA EC, SOFFT EC, SOL EO and SOL EC procedures. The mean performance duration values for TREC, SOFFA EC, SOFFT EC, SOL EO AND SOL EC were significantly negatively correlated with age. Although majority of tests were negatively correlated with body mass index, the correlations were not statistically significant.
CONCLUSION: Age significantly affects selected static balance performance whereas sex and body mass index do not significantly affect selected static balance performance. The normative values generated in this study are inconclusive because of inadequate sample size, particularly in the older age group. The results, however, showed the potential value of the 5th percentile as a normative norm in systematically assessing the involvement of the vesticular, visual and proprioceptive organs i balance function.

INTRODUCTIONThe lateral tarsal strip procedure (LTS) was first reported by Anderson and Gordy in 1979 for the management of paralytic or senile eyelid laxity. Since its description, the LTS procedure has been subject to several modifications by various authors. In this study, we described the Looi suture technique, a small modification in the technique of suturing the LTS to the lateral orbital wall periosteum. Using this technique, the surgeon achieves a larger area of contact between the anterior surface of the tarsal strip and the lateral orbital wall periosteum, promoting a stronger adhesion. With a double-armed suture, the technique also allows for adjustment of the lower lid tension to avoid over- or under-correction of horizontal lid laxity. This study aimed to evaluate the technique.
MATERIALS AND METHODSThis was a retrospective non-comparative case series of 39 eyelids of 31 patients who underwent LTS with Looi suturing technique for the correction of involutional lower lid laxity which had resulted in either entropion or ectropion. In this procedure, a novel technique utilising a double armed 5/0 Ethibond suture is used to secure the LTS to the lateral orbital rim, with the aim of increasing appositional contact between the LTS and periosteum.
RESULTSIn 36 eyelids with entropion, the procedure was combined with lower lid retractor repair, and in 3 eyelids with ectropion, with medial tarsoconjunctivoplasty. Surgery was successful in 37 of 39 eyelids (94.87%) after one procedure. The remaining 2 eyelids required repeat procedures to achieve anatomical success. Both cases had been performed by trainee surgeons under supervision. Postoperative follow-up period ranged from 1 day (in a visiting overseas patient) to 2 years.
CONCLUSIONThis study described the Looi suturing technique in performing the LTS procedure and we found it a simple and effective modification when dealing with lower lid laxity.

Dengue infection is endemic in South East Asia and parts of the Americas. Dengue
hemorrhagic fever is characterized by vascular permeability, coagulation-disorders and
thrombocytopenia, which can culminate in hypotension i.e. dengue shock syndrome.
Hypopituitarism arising as a complication of dengue is extremely rare. Hemorrhagic pituitary
apoplexy of pre-existing pituitary adenomas has been rarely reported in dengue. We describe
an uncommon case of hypopituitarism in a dengue shock syndrome survivor without known
pituitary adenoma. A 49 years old nulliparous lady (from Kuala Lumpur, Malaysia) presented
with typical symptoms of hypocortisolism. Postural hypotension was evident with normal
secondary sexual characteristics. Further history revealed that she survived an episode of
dengue shock syndrome 6 years ago where premature menopause developed immediately
after discharge, and subsequently insidious onset of multiple hormonal deficiencies indicative
of panhypopituitarism. There were no neuro-ophthalmological symptoms suggestive of pituitary
apoplexy during hospitalization for severe dengue. Magnetic resonance imaging of the pituitary
6 years later revealed an empty sella. Autoimmune screen and anti-thyroid peroxidase
antibodies were negative. We describe a rare possible causative association of severe dengue
with panhypopituitarism without known pituitary adenoma, postulating pituitary infarction
secondary to hypotension (mimicking Sheehan’s syndrome), or a direct viral cytopathic effect.
Subclinical pituitary apoplexy secondary to asymptomatic pituitary hemorrhage however
cannot be excluded. Future research is required to determine the need for and timing of
pituitary axis assessment among dengue shock syndrome survivors.

Introduction: Psoriasis is a chronic recurrent inflammatory skin disease and poses a lifelong
burden. Psoriasis is now considered a systemic inflammatory disease. Increasing epidemiological
studies have established the role of psoriasis as an independent risk factor in the development of
metabolic syndrome and its components. This has led to changes in standard of care
recommendations for patients with psoriasis. We conducted a clinical audit on “adequacy of care in
patient with psoriasis”.
Objective: To examine current trend of practice in the treatment of adults with psoriasis in
Dermatology clinic (tertiary referral centre), Penang Hospital. This study also aims to determine the
adequacy of care in psoriasis patients in general, and those on systemic agents in specific.
Method: A retrospective study examined all adult psoriasis patients who visited Dermatology
Clinic, Penang Hospital within 1st July - 31st July 2009. Only those who have been on follow-up for
at least 1 year were included in the study. Demographic characteristics, disease burden and details
of psoriasis management were documented and analysed. Standards were derived from
recommendations of the British Association of Dermatologists (BAD) and American Academy of
Dermatology (AAD).
Results: Of the 112 patients, 67 were males (59.8%). The mean age of patients was 48.8 years. Fifty
(44.6%) were Chinese, 35 Malay (31.3%), 26 Indians (23.2%) and 1 foreigner (0.9%). The mean
frequency of clinic visit was 8.2. Forty-seven patients required systemic agents to achieve better
disease control. Eighty-three (74.1%) patients were offered “Psoriasis Education Programme”.
Percentage of patients who had their severity scoring done by using the DLQI, BSA & Pain score
were 73.2%, 90.2% and 85.7% respectively. Only less than 50% of our patients were offered
“Metabolic Syndrome Risk Factors Screening”. Of those on systemic agents, only 87.2% and 46.8%
of patients, had their baseline and follow up blood investigations done respectively.
Conclusion: The care of psoriasis patients in Dermatology Clinic, Penang Hospital is still not
adequate. Particular areas of concern include blood monitoring for those on systemic agents and
screening for metabolic syndrome risk factors.
Remedial measures: Guidelines have been designed to create awareness and to educate doctors and
patients on psoriasis and its association with metabolic syndrome. This includes a flow chart / tables
to facilitate monitoring and screening of patients. Patients will be given pamphlets on the general
knowledge on psoriasis, treatments and the risk of co-morbidities.
