INTRODUCTION: Benign tumours of the parotid gland constitute about 80% of parotid tumours. The most common benign tumour of the parotid gland is pleomorphic adenoma. Other conditions, like Kimura's disease, may mimic a tumour when they present as a parotid mass. Various modes of treatment have been advocated for the treatment of benign parotid lesions, ranging from enucleation to near-total parotidectomy.

MATERIAL AND METHODS: This is an audit of an 18-year period where 173 lesions of the parotid gland (34 malignant and 139 benign lesions) were treated by the author.

RESULTS: There were 139 benign lesions, of which 123 were benign tumours and 16 non-tumour conditions. Fourteen cases of recurrent pleomorphic adenoma of parotid that had been treated elsewhere were also operated on. Near-total parotidectomy was performed on all these cases with benign lesions.

CONCLUSIONS: There has been no recurrence in all the patients who was treated this way. Near-total parotidectomy should be considered when there is a need to treat benign parotid swellings.

Hypospadias is a congenital deformity characterised by an abnormally located urethral opening, that could occur anywhere proximal to its normal location on the ventral surface of glans penis to the perineum. Many operations had been described for the management of this deformity.

Kimura's disease of parotid gland presenting as solitary parotid swelling

Arshad AR

Head Neck, 2003 Sep;25(9):754-7.

PMID: 12953311

Kimura's disease is a chronic inflammatory disorder of unknown etiology commonly seen among orientals and characterized histologically by lymphatic follicles, vascular proliferation, and marked eosinophilic infiltration. It has a predilection for the head and neck region. The lesion is benign but can be mistaken to be a malignant lesion.

Parotid swellings are uncommon. Over a twelve-year period, 110 cases of parotid swellings were treated at the Department of Plastic Surgery, Hospital Kuala Lumpur, of which 97 cases were histologically proven to be parotid tumours. 75% of these tumours were benign tumours, and 80% of the benign tumours were pleomorphic adenomas. Among the malignant tumours, 6 cases were adenoid cystic carcinoma and 5 were carcinoma ex-pleomorphic adenoma. There were equal number of male to female patients, with an age range of 14 to 83 years. There is a positive correlation between the final histological diagnosis and FNAC results in 74% of cases. Surgical treatment of choice for benign parotid tumours was near-total parotidectomy whilst for malignant tumours was total radical parotidectomy with sural nerve graft.

Incomplete midline cleft of lower lip

PMID: 7748879

Midline cleft of the lower lip is defined as a midline vertical cleft of the soft tissue of the lower lip. It may present with a midline cleft of the mandible. It may also be accompanied by other congenital anomalies such as a cleft tongue, ankyloglossia, a heart lesion, and absence of the hyoid bone. The etiologic cause is thought to be a failure of mesodermal penetration into the midline structures of the first branchial arch. This case report is on a female child who presented with an incomplete midline cleft of the soft tissue of the lower lip. It was surgically corrected with a vertical wedge excision and primary closure.

Fulltext Surgical management of large desmoid tumour of the anterior abdominal wall

Desmoid tumours are uncommon. They are locally invasive and incomplete excision leads to recurrence, which can pose a significant management challenge. Patients therefore require effective treatment, which essentially entails tumour excision with a clear surgical margin. The resulting wide defect may lead to difficulty in closure of the anterior abdominal wall. We report our experience in treating large desmoid tumours of the anterior abdominal wall. Between January 2000 and December 2001, three patients with large desmoid tumour of the anterior abdominal wall were treated with wide excision, which included a 3-cm margin of uninvolved tissues. This led to a considerable abdominal wall defect. The peritoneal defect was closed as a separate layer, though under considerable tension, while the abdominal wall musculature defect was closed with a polypropylene mesh. All three patients recovered well with no immediate or late postoperative morbidity. Follow-up until December 2006 has not revealed any tumour recurrence or hernia development. Wide excision of an anterior abdominal wall desmoid tumour with a clear margin of 3 cm including the peritoneum should be considered when managing such tumours. Closure under tension of the peritoneum did not seem to produce any morbidity.

J Craniofac Surg, 2008 Jan;19(1):175-83.

PMID: 18216685 DOI: 10.1097/scs.0b013e3181534a77

This is a study on 124 patients who were treated by the authors over a 19-year period. There were 48 male and 76 female patients. The age range of these patients at the time of treatment was between 4 months and 32 years. There was no family history of similar deformity. All of these patients come from a socially low-income group. Fourteen patients had accompanying congenital amputation of fingers, toes, or limbs. Two had oral cleft lip and palate. The surgical treatment was medial orbital wall osteotomy and excision of encephalocele. There were two mortalities and five patients who had complications that needed secondary surgical intervention. Thirty-eight patients are still under follow up without any complaints.

Fulltext An audit of inpatient case records and suggestions for improvements

Med J Malaysia, 2000 Sep;55(3):331-40.

PMID: 11200713

A study was carried out in Kuala Lumpur Hospital to review the adequacy of documentation of bio-data and clinical data including clinical examination, progress review, discharge process and doctor's identification in ten of our clinical departments. Twenty criteria were assessed in a retrospective manner to scrutinize the contents of medical notes and subsequently two prospective evaluations were conducted to see improvement in case notes documentation. Deficiencies were revealed in all the criteria selected. However there was a statistically significant improvement in the eleven clinical data criteria in the subsequent two evaluations. Illegibility of case note entries and an excessive usage of abbreviations were noted during this audit. All clinical departments and hospitals should carry out detailed studies into the contents of their medical notes.

Hypoglossia congenita with anterior maxillo-mandibular fusion

Arshad AR, Goh CS

Br J Plast Surg, 1994 Mar;47(2):139-41.

PMID: 8149059

Two cases of hypoglossia congenita with anterior maxillo-mandibular fusion are reported. One is a case of hypoglossia with anterior maxillo-mandibular fusion and the other is a case of hypoglossia-hypodactylia with anterior maxillo-mandibular fusion. This condition presents the anaesthetist with the problem of airway management during the surgery. A simple technique using a nasopharyngeal tube was used for these two cases, with satisfactory results.

Fulltext A study of cleft lip and palate in neonates born in a large Malaysian maternity hospital over a 2-year period

Boo NY, Arshad AR

Singapore Med J, 1990 Feb;31(1):59-62.

PMID: 2333547

Out of 52,379 babies delivered in the Maternity Hospital, Kuala Lumpur, over a 2-year period, 64 were born with cleft lip and/or palates. The rate of occurrence of cleft was 1.24 per 1000 livebirths or 1.20 per 1000 deliveries. The Chinese babies had the highest incidence (1.9 per 1000 deliveries) while the Malays had the lowest (0.98 per 1000 deliveries). The most common type was unilateral cleft of the primary and secondary palates. Among the Indian babies, cleft of the secondary palate was most common. 18.8 percent of all the affected babies had positive family history of cleft. 10.9% of the mothers of affected babies had positive history of drug ingestion especially Chinese herbs during pregnancy. Associated congenital abnormalities occurred in 15.6% of the babies with cleft lip and/or palate.

Head Neck, 2008 Apr;30(4):544-8.

PMID: 17972311 DOI: 10.1002/hed.20708

BACKGROUND: Sebaceous nevus is a benign congenital epidermal nevus. Its association with basal cell carcinoma is well known.
METHOD: This is a case report of sebaceous carcinoma complicated by both basal cell carcinoma and squamous cell carcinoma.
RESULTS: The behavior of this tumor is very aggressive, resulting in poor prognosis.
CONCLUSIONS: All sebaceous nevi should be excised early.

Fulltext MicroRNAs and Target Genes As Biomarkers for the Diagnosis of Early Onset of Parkinson Disease

Among the neurodegenerative disorders, Parkinson's disease (PD) ranks as the second most common disorder with a higher prevalence in individuals aged over 60 years old. Younger individuals may also be affected with PD which is known as early onset PD (EOPD). Despite similarities between the characteristics of EOPD and late onset PD (LODP), EOPD patients experience much longer disease manifestations and poorer quality of life. Although some individuals are more prone to have EOPD due to certain genetic alterations, the molecular mechanisms that differentiate between EOPD and LOPD remains unclear. Recent findings in PD patients revealed that there were differences in the genetic profiles of PD patients compared to healthy controls, as well as between EOPD and LOPD patients. There were variants identified that correlated with the decline of cognitive and motor symptoms as well as non-motor symptoms in PD. There were also specific microRNAs that correlated with PD progression, and since microRNAs have been shown to be involved in the maintenance of neuronal development, mitochondrial dysfunction and oxidative stress, there is a strong possibility that these microRNAs can be potentially used to differentiate between subsets of PD patients. PD is mainly diagnosed at the late stage, when almost majority of the dopaminergic neurons are lost. Therefore, identification of molecular biomarkers for early detection of PD is important. Given that miRNAs are crucial in controlling the gene expression, these regulatory microRNAs and their target genes could be used as biomarkers for early diagnosis of PD. In this article, we discussed the genes involved and their regulatory miRNAs, regarding their roles in PD progression, based on the findings of significantly altered microRNAs in EOPD studies. We also discussed the potential of these miRNAs as molecular biomarkers for early diagnosis.
