Delayed Operative Management of Fractures of the Lateral Condyle of the Humerus in Children

Purpose

Delayed presentation of lateral condylar fractures of the humerus is relatively common in the developing regions of the world. These fractures are difficult to manage because of the displacement and fibrosis around the condylar fragment secondary to the delay. There is a paucity of literature concerning the management of these fractures. An oft repeated finding is the requirement of extensive dissection around the fragment for proper reduction. The purpose of this study was to assess the efficacy of surgical management of lateral condylar fractures with delayed presentation.

Methods

We assessed the results of lateral condylar fracture fixation in 20 cases with delayed presentation.

Results

The lateral condylar fractures in patients with a delayed presentation can be managed surgically with good results.

Conclusions

Open reduction and internal fixation should continue to be the method of choice for the management of lateral condylar fractures which report late for management.

Comparing the morbidity of external laryngeal nerve injury in thyroid surgery with and without identifying the nerve using intraoperative neuromonitoring

OBJECTIVE

To describe and determine the possibility of surgical trauma to the external branch of the superior laryngeal nerve and to assess the role of intraoperative neuromonitoring in thyroid surgery.

DESIGN AND SETTING

Prospective, randomized, controlled study in a teaching Hospital Universiti Sains Malaysia (HUSM), Kota Bharu, Kelantan, Malaysia.

SUBJECTS

Forty two patients of both genders, whom underwent thyroid surgery divided into two groups (21 patients control group and 21 patients study group) in HUSM and were randomly selected for our study.

METHODS

The use of nerve monitoring and proper surgical technique of upper thyroid pole dissection followed by its lateralization and exposure of cricothyroid space were performed in each subject in study group in order to preserve EBSLN after its identification. In control group upper thyroid vessels were ligated close to the upper thyroid pole without any effort of EBSLN identification.

RESULTS

Total of 42 (35 females and 7 males) patients who underwent thyroid surgery in a period of 2 years. Evaluation of all subjects 1 case in control group presented with symptoms of EBSLN injury.

CONCLUSION

Intraoperative identification and neuromonitoring can avoid injury to the EBSLN and prevent its sequential changes in voice especially for those who professionally depend to their voice.

Intraparotid facial nerve schwannoma: a case report

Schwannoma in the head and neck region is very rare. The tumour occurring in the intraparotid facial nerve is even rarer. A patient presenting with a parotid swelling with facial nerve paralysis is not pathognomonic of a facial nerve schwannoma. However it may occur because enlargement of the parotid, by any kind of tumour especially a malignant one can cause facial nerve paralysis. We report a case of an intraparotid facial nerve schwannoma, in a patient who presented with parotid enlargement and facial nerve paralysis.

Harmonic scalpel for a bloodless partial glossectomy: a case report

Tongue surgery is almost always complicated by intraoperative bleeding. Its rich blood supply especially from the lingual vessels makes the operative field bloody. Electrocautery has been widely used to replace cold scissors in order to achieve better hemostasis. The use of ultrasonic harmonic scalpel for glossectomy is still new in this country. We report a case of partial glossectomy using the harmonic scalpel in a patient who had a squamous cell carcinoma of the lateral border of the tongue.

Massive goiter with retrosternal extension encasing trachea and esophagus

Massive goiter with retrosternal extension may impose additional risk such as difficult intubation, tracheomalacia, and possibility of different incision and approach including sternotomy. We would like to report a case of massive goiter encasing major neck structures and how it was managed.

Oropharyngeal gonorrhoea: rate of co-infection with sexually transmitted infection, antibiotic susceptibility and treatment outcome

The aim of the present study is to investigate the rate of co-infections with other sexually transmitted infections (STIs), antibiotic susceptibility and management of oropharyngeal gonorrhoea diagnosed in a busy genitourinary medicine clinic. The method involved a retrospective study on consecutive patients diagnosed with oropharyngeal gonorrhoea. A total of 131 patients were diagnosed with oropharyngeal gonorrhoea over the study period. The median age of the infected patients was 28 (interquartile range: 22 to 35) years. Forty-one (31%) of patients were younger than 24 years. High rates of co-infection with urethral gonorrhoea (37%), rectal gonorrhoea (37%) or chlamydial infection (16%) were identified. Thirty patients (23%) had only oropharyngeal infection. Twenty-two (17%) patients' isolates showed resistance to at least one antibiotic. Antibiotic resistance among oropharyngeal gonococcal isolates was above 5% between 2000 and 2009. Test-of-cure (TOC) was carried out for only 63 (48%) of patients; none had positive culture. Among 46 isolates treated with cefixime 400 mg/stat, 27 (59%) had TOC; all were negative. Repeat TOC was not carried out for any of the patients. In conclusion, successful management of oropharyngeal gonorrhoea should comprise of counselling, partner notification and TOC after treatment with appropriate antibiotic regimen.

Unilateral adductor vocal cord palsy treated with the titanium vocal fold medializing implant (TVFMI)

Vocal cord palsy secondary to recurrent laryngeal nerve injury may be attributable to trauma, infiltrating neoplasm, congenital cardiac anomaly and others. Regardless the causes, majority of unilateral adductor palsy cases are usually managed by speech rehabilitation in order to allow compensation. In selected cases, medialization procedure may be required to achieve a complete glottal closure during phonation. Multiple techniques have been developed to achieve this goal. This case report illustrates the recent advancement in vocal fold medialization procedure, which has not been widely practiced in Malaysia.

Nasopharyngeal Carcinoma Database

Nasopharyngeal carcinoma (NPC) is a cancer which is common in Asia. We report the establishment and early results of a multi-institutional prospective study of nasopharyngeal carcinoma, which seeks to systematically collect data as well as blood and tumour tissue samples from patients diagnosed with nasopharyngeal cancer at six centres in Malaysia. A total of 484 confirmed NPC cases were reported from the six participating centres between 1st July 2007 and 29th February 2008. Of these, 225 were newly diagnosed cases, 53 were recurrent cases and 206 were in remission at the time of reporting. Amongst the newly diagnosed cases, the most common presenting symptom was the presence of neck lumps (42%). Ophthalmo-neurologic symptoms were the presenting symptoms of 11% of the new cases. The majority of cases (75%) presented at stage III/IV.

An extensive sinonasal osteosarcoma mimicking chondrosarcoma

Osteosarcoma is a rare tumour in the sinonasal region. Early diagnosis is essential for adequate management and better prognosis and this requires a meticulous histopathological examination. Reported is a case of osteosarcoma misdiagnosed as chondrosarcoma and treated by surgery followed by radiotherapy. However, appropriate diagnosis and pre-operative chemotherapy would have been significant in the prognosis. The pitfall of accurate diagnosis and the subsequent treatment is discussed in order to find the ways to maximize five years survival which is not more than 25% in this type of lesions.

The Macklin effect--pneumomediastinum and pneumopericardium following blunt chest trauma

Pneumomediastinum and pneumopericardium following blunt chest trauma are rare. Diagnosis is by chest radiograph and CT Scan. They have to be identified and treated accordingly. Usually, pneumomediastinum and pneumopericardium are self-limiting requiring no specific therapy. However, vigilance and a continuous monitoring of the vital signs are necessary.

Laser tonsillotomy in children with tonsillar hyperplasia

Tonsillectomy in children is performed on a regular basis in ENT. The indications are chronic tonsillitis, sleep apnea to deeper structures. The natural history of tonsillar hyperplasia is regression when a child is six years beyond. In children with bilateral tonsillar hyperplasia we studied the use of laser as an alternative procedure to reduce the bulk of the tonsillar mass. Children with symptoms of bilateral tonsillar hyperplasia underwent laser tonsillotomy. The tonsils were dissected using carbon dioxide (CO2) laser. The tonsillar bed was left untouched. Intraoperative and postoperative conditions were noted.

Ingestion of a voice-master prosthesis followed by a potentially fatal aspiration

Various complications are associated with the use of indwelling voice prostheses. We present problems faced by a patient with his Voice-Master prosthesis, the ingestion of the prosthesis followed by a potentially fatal aspiration. The Voice-Master is unique in that in can be re-inserted. The safety strap is removed after primary insertion once the prosthesis is secure. However, during re-insertions this safety mechanism is no longer present. Therefore we recommend the placement of a temporary stitch or tie to minimize the risks of ingestion or aspiration of the prosthesis during re-insertions.

The management of retinal vein occlusion: is interventional ophthalmology the way forward?

Retinal vein occlusions (RVO) are the second commonest sight threatening vascular disorder. Despite its frequency treatments for RVO are unsatisfactory and include several that have not been tested by large, well designed, prospective, randomised controlled trials. There is also the lack of long term follow up in many of the available small uncontrolled studies, and the timings of interventions are haphazard. This review aims to evaluate the current knowledge relating to the pathogenesis, suggested treatments for the different types of RVO, and their complications. Isovolaemic haemodilution is of limited benefit and should be avoided in patients with concurrent cardiovascular, renal, or pulmonary morbidity. Evidence to date does not support any therapeutic benefit from radial optic neurotomy, optic nerve decompression, or arteriovenous crossing sheathotomy on its own. Vitrectomy combined with intravenous thrombolysis may offer promise for central RVO. Similarly, vitrectomy combined with arteriovenous sheathotomy intravenous tissue plasminogen activator may offer benefits for branch RVO. RVOs occur at significantly high frequency to allow future prospective randomised controlled studies to be conducted to evaluate the role of different therapeutic modalities singly or in combination.

Hearing screening of infants in Neonatal Unit, Hospital Universiti Sains Malaysia using transient evoked otoacoustic emissions

The objective of this prospective study was to report on the prevalence of hearing impairment in the neonatal unit population. From 15 February 2000 to 15 March 2000 and from 15 February 2001 to 15 May 2001, 401 neonates were screened using transient evoked otoacoustic emissions (TEOAE) followed by second-stage screening of those infants who failed the initial test. Eight (2 per cent) infants failed one ear and 23 (5.74 per cent) infants failed both ears, adding up to 7.74 per cent planned for second-stage screening. Five out of 22 infants who came for the follow up failed the screening, resulting in a prevalence of hearing impairment of 1 per cent (95 per cent confidence interval [95% CI]: 0.0–2.0). Craniofacial malformations, very low birth weight, ototoxic medication, stigmata/syndromes associated with hearing loss and hyperbilirubinaemia at the level of exchange tranfusion were identified to be independent significant risk factors for hearing impairment, while poor Apgar scores and mechanical ventilation of more than five days were not. In conclusion, hearing screening in high-risk neonates revealed a total of 1 per cent with hearing loss. The changes in the risk profile indicate improved perinatal handling in a neonatal population at risk for hearing disorders.

Age related macular degeneration and sun exposure, iris colour, and skin sensitivity to sunlight

BACKGROUND/AIM

It has been suggested that sun exposure may be a risk factor for age related macular degeneration (AMD) and that skin sensitivity to sunlight and iris colour could be confounding factors. The aim was to investigate this further in the white population.

METHODS

446 cases with end stage AMD were compared with 283 spouse controls. Data on sun exposure, places of residence, iris colour, subjective assessment of change in iris colour, hair colour at age 20, and skin sensitivity were obtained using a questionnaire. Iris colour was graded clinically by comparison with standard photographs. AMD was graded using stereoscopic colour fundus photographs as well as clinical examination and was defined as the presence of geographic atrophy or choroidal neovascularisation. All variables were included in a multiple logistic regression model including age, sex, and smoking.

RESULTS

There was no association between AMD and sun exposure or related factors except for the suggestion of an association between sunburn prone skin type and geographic atrophy which reached borderline significance.

CONCLUSIONS

No significant association between AMD and sun exposure, iris colour, change in iris colour, or hair colour was demonstrated.

Smoking and age related macular degeneration: the number of pack years of cigarette smoking is a major determinant of risk for both geographic atrophy and choroidal neovascularisation

BACKGROUND/AIMS

There is evidence that smoking is a risk factor for age related macular degeneration (AMD). However, not all studies have demonstrated this association and several key questions about the role of smoking in AMD have still to be determined. The aim of this study was to further investigate this relation for both choroidal neovascularisation (CNV) and geographic atrophy (GA).

METHODS

To investigate the relation between smoking and the risk of developing age related macular degeneration (AMD) in white people, 435 cases with end stage AMD were compared with 280 controls. All subjects had graded stereoscopic colour fundus photography and AMD was defined as the presence of GA or CNV. Smoking history was assessed using multiple parameters in a detailed questionnaire.

RESULTS

Comparison of current and former smokers with non-smokers was consistent with smoking being a risk factor for AMD but did not reach statistical significance. There was a strong association between AMD and pack years of cigarette smoking (p = 0.002), the odds ratio increasing with the amount smoked; for subjects with more than 40 pack years of smoking the odds ratio was 2.75 (95% CI 1.22 to 6.20) compared with non-smokers. Both types of AMD showed a similar relation; smoking more than 40 pack years of cigarettes was associated with an odds ratio of 3.43 (95% CI 1.28 to 9.20) for GA and 2.49 (95% CI 1.06 to 5.82) for CNV. Stopping smoking was associated with reduced odds of AMD and the risk in those who had not smoked for over 20 years was comparable to non-smokers. The risk profile was similar for males and females. Passive smoking exposure was associated with an increased risk of AMD (OR 1.87; 95% CI 1.03 to 3.40) in non-smokers.

CONCLUSIONS

The authors have demonstrated a strong association between the risk of both GA and CNV and pack years of cigarette smoking. This provides support for a causal relation between smoking and AMD. They also show an increased risk for AMD in non-smokers exposed to passive smoking. Stopping smoking appears to reduce the risk of developing AMD.
