Methaemoglobinaemia: a rare cause of chest pain, hypoxia and cyanosis.

A man in his 20s presented with severe left-sided chest pain, shortness of breath and acute confusion. Initial examination revealed central cyanosis, normal heart sounds, vesicular breath sounds in both lung fields and a bruised right calf. The patient reported that he had recently injured his right leg and that he had not taken medication prescribed for blood clots for several days. Peripheral oxygen saturations were 85% despite high flow oxygen via a non-rebreather mask. ECG revealed sinus tachycardia. Arterial blood gas sampling confirmed hypoxaemia. Given the history and the severe hypoxia, he was managed for pulmonary embolism initially.Closer inspection of his arterial blood results showed a methaemoglobin percentage of 20.4%. He was given intravenous methylene blue which resulted in resolution of his symptoms within 30 min. He subsequently confirmed that he was undergoing genetic testing for likely congenital methaemoglobinaemia.

Ludwig's angina in Nigeria: The disease of the poor and health inequality!

AIM: highlight the health inequality and identify opportunities to improve the care delivered to the patients who suffer from Ludwig's angina which could have national and international clinical impact. MATERIALS AND METHODS: Data was collected from three major oral and maxillofacial centers, in Nigeria including Benin, Lagos and Kano. A protocol was developed for data collection which included demographic details, socio-economic status, management of the air way, the associated morbidities and mortalities. RESULTS: Forty-nine were managed in Benin, 57 in Lagos and 66 in Kano. Diabetes was the most prevalent underlying systematic condition, affecting 21% of the Ludwig's angina patients in Lagos. Poverty was a common denominator, 90% of the patients from Kano were unemployed compared to 23% and 8% from Lagos and Benin respectively. For most of the patients, the airway was monitored. Incision and drainage were carried out in most of the cases at Benin and Lagos, but it was only considered in 50% of the cases in Kano. Mortality ranged from 4% in Benin to 12% in Lagos and it was as high as 19% in Kano. CONCLUSION: poor access to oral healthcare, unemployment and low socio-economic status are important predisposing factors of Ludwig's angina.

Predictors of late presentation to renal dialysis: a cohort study of linked primary and secondary care records in East London.

OBJECTIVES: The outcomes and experience of care for patients who start renal replacement therapy (RRT) in an unplanned manner are worse than for those who have planned care. The objective of this study was to examine the primary care predictors of unplanned starts to RRT. DESIGN: Retrospective cohort study with linked primary care and hospital data. SETTING: 128 general practices in East London with a combined population of 1 043 346 people. PARTICIPANTS: 999 consecutive patients starting dialysis at Barts Health National Health Service Trust between September 2014 and August 2017. PRIMARY OUTCOME MEASURES: Unplanned versus a planned start to dialysis among the cohort of 389 patients with a linked primary care record. An unplanned start to dialysis is defined as receiving nephrology care in the low clearance clinic (or equivalent) for less than 90 days. A planned start is defined as access to pre-dialysis counselling and care for at least 90 days prior to commencing dialysis. RESULTS: The adjusted logistic regression analysis showed that the most important modifiable risk factors for unplanned dialysis were the absence of a chronic kidney disease (CKD) code in the general practice (GP) record (OR 8.02, 95% CI 3.65 to 17.63) and the absence of prescribed lipid lowering medication (OR 2.37, 95% CI 1.05 to 5.34). Other contributing factors included male gender and a greater number of long-term conditions. CONCLUSIONS: Improving CKD coding in primary care and the additional review and clinical scrutiny associated with this may contribute to a further reduction in unplanned RRT rates.

Unilateral Cleft Lip Repair: Assessment of Outcome of Olokun-Olaitan Vermillion Flap Approach.

This study aimed to assess the outcome of our novel free-hand approach. Numerous cleft lip repair techniques exist, all of which involve incisions on skin and excision of tissue. Unilateral cleft lip is the result of failure of migration of orofacial tissues in-utero. Cleft lip repair should ideally involve an approach that simulates nature by avoiding skin incision and tissue excision, as these are not known to occur in the normal natural sequence of events.Without incising skin or excising any tissue, vermillion flaps were raised exposing the muscular layer and edges of skin and mucosa. Similar tissue types were advanced and sutured across the cleft, replicating what should have occurred normally.All 28 patients (100%) treated using our technique had competent lips. Acceptable symmetry of the vermillion was achieved in 24 (85.7%) of the patients. Lip symmetry was judged to be acceptable in 22 (78.6%). Symmetry of the nose was acceptable in 18 (64.3%) of patients.The Olokun-Olaitan vermillion flap approach proved effective in the repair of unilateral cleft lip, as it compared very favorably with results obtained using Millard's technique.

Prevention of Earlobe Keloid Recurrence After Excision: Assessment of the Value of Presurgical Injection of Triamcinolone.

The ear is commonly involved in keloid formation, being often pierced. This study estimates the value of pre-excision triamcinolone injection of earlobe keloid, by comparing recurrence rates in patients who only received postexcision triamcinolone injection to those who had it administered before and after excision.The prospective intervention study involved 18 keloid lesions in as many consenting patients who presented with pedunculated earlobe keloid from January 2005 to January 2007.Triamcinolone doses were administered 10 mg/cm of lesion or sutured excision site. Each patient was followed-up for 10 years. Aggregate length of keloid lesions at presentation was 24.4 cm in Group A and 26.5 cm in Group B. Aggregate length of postexcision sutured wound in Group A was 16.1 cm, and 14.8 cm in Group B. Group A patients received a total of 1610 mg of triamcinolone, while a total of 4660 mg of same drug was administered to Group B patients, among whom 3180 mg was delivered presurgically. Total number of clinic visits during the course of treatment in Group A was 10, while that of Group B was 22. No patient with recurrent keloid was recorded in both groups.The authors concluded that there is no advantage to presurgical injection of triamcinolone when excision is considered as part of treatment protocol of a keloid lesion. This study helps to eliminate an ostensibly needless part of a commonly used treatment protocol.

Patient's Self-Assessment of Social-Approval After Mandibulectomy with Disarticulation: the Necessity for Jaw Reconstruction Following Loss of Facial Symmetry in a Resource-Poor African Setting.

OBJECTIVE: Mandibulectomy with disarticulation is usually carried out without reconstruction in Low-Income-Countries. Lower standards of living are usually acceptable and adapted to, in poor societies. This study compares patient's self-assessment of social approval among reconstructed and non-reconstructed cases of mandibulectomy with disarticulation in a resource-poor African setting. MATERIAL AND METHOD: This questionnaire-based study documented patient's self-assessment of social approval of themselves following mandibulectomy with disarticulation. 12 derived queries were administered on each patient, to test what they perceived of social acceptability of their facial features following mandibulectomy. RESULTS: All 10 patients who underwent mandibular reconstruction reported that they felt confident engaging in all forms of social activity, while all 10 who had resection without reconstruction did not. CONCLUSION: The low social approval perceived by patients who have undergone mandibulectomy with disarticulation without reconstruction necessitates that surgeons must strive to reconstruct this anatomical region even under circumstances of severe resource-constraint. The culture in the third-world is not supportive of patients who have not undergone reconstruction following resection, in spite of being victims of all-pervading poverty. LEVEL OF EVIDENCE: Level IV, investigative study.

Ranula Decompression Using Stitch and Stab Method: The Aluko Technique.

BACKGROUND: A ranula is a cystic lesion in the floor of the mouth, formed either as a retention cyst or pseudocyst as a result of extravasation of mucus in the surrounding tissue. It may be treated by micro-marsupialization, marsupialization or excision of lesion with or without the associated salivary gland. Marsupialization is usually achieved by cutting a slit and thereafter stitching the edges such that the epithelium of the exterior becomes continuous with that of the interior of a cyst. A stitch-and-stab technique of achieving patency of the created slit of marsupialized ranula is hereby presented. METHOD: A stitch and stab technique using four parallel consecutive strokes of the needle with attached polyglactin 910 suture material in alternately opposing directions was employed in treatment of 31 consecutive ranula patients. RESULTS: 100 % success was achieved using this technique in 31 ranulas. CONCLUSION: This stitch-and-stab technique for marsupialization has proven to be very successful. It is recommended for use by the general medical community, as it requires the Clinician to possess only minimal surgical skills. Bartholin's cyst can be so treated.

Reconstruction of tooth-bearing portion of mandible using polyglactin 910 sutures for internal fixation in the third-world: functional and cosmetic outcome.

BACKGROUND: This study analyzed the cosmetic and functional outcome of cases involving reconstruction of tooth-bearing portion of the lower jaw, using a polyglactin 910 suture for fixation. PATIENTS AND METHOD: This prospective intervention study documented the treatment outcome in 25 consecutive adult patients, who underwent immediate mandibular reconstruction following segmental resection of tooth-bearing portion of mandible. Cortico-cancellous bone graft was taken from the inner table of iliac bone, sparing the crest. Use of post-surgical inter-maxillary fixation was avoided. RESULTS: Twenty-five patients were recruited for the study. Seventeen were males and eight were females. Their ages ranged from 18 to 50 years, with a mean of 30.0 years. Average length of grafted bone was 9.8 cm. Following surgery, all 25 (100%) patients were judged to have satisfactory facial symmetry. One (4.0 %) had altered dental occlusion. Twenty-five (100%) had satisfactory bone union. All of the patients claimed to masticate satisfactorily. Assessment was carried out at the last post-operative follow-up visit for each patient who ranged between 22 and 83 months. CONCLUSION: Use of polyglactin 910 suture material for fixation in mandibular reconstruction following segmental resection of tooth-bearing portion has proven to be a cosmetic and functional success. It may serve as alternative for those among whom conventional treatment methods may be contraindicated. This method of bone fixation may serve as a reliable and much cheaper alternative in low-income countries. LEVEL OF EVIDENCE: Level IV, therapeutic study.

Strategy for Successful Management of Facial Keloid Using Triamcinolone Injection as Adjunct to Surgery.

The literature on keloids is replete with authors expressing frustration with treatment results. Triamcinolone is effective in shrinking keloids and preventing their recurrence following excision, if delivered successfully. Strategies for effective delivery of drug are presented: recommended needle size, use of metal syringe, slow injection to avoid skin rupture, and delayed withdrawal of needle after injection. The futility of expecting pedunculated keloids to be completely flattened by steroid injection alone is mentioned.

Management of mandibular fractures in a developing country: a review of 314 cases from two urban centers in Nigeria.

BACKGROUND: This study was designed to establish the current demographic and treatment patterns of mandibular fractures in two urban centers (Lagos University Teaching Hospital, Lagos, and National Hospital, Abuja) in Nigeria. METHODS: All cases of mandibular fractures diagnosed and treated at the Department of Oral and Maxillofacial Surgery, Lagos University Teaching Hospital, Lagos (1998-2007) and Department of Oral and Maxillofacial Surgery, National Hospital, Abuja, Nigeria (2001-2007) were reviewed. Data collected included age, sex, etiology of fracture, anatomic site of fracture, associated maxillofacial fracture, types of treatment, and postoperative complications. RESULTS: The highest incidence of mandibular fractures (49.3%) occurred in the age group 21-30 years and the lowest in the age group 0-10 years, with male preponderance in nearly all age groups. Road traffic crashes (RTC) were the leading cause (67.5%), followed by assault (18.8%), and gunshot. Of the RTC cases, 85 (40%) were sustained from motorcycle-related crashes. The commonest site of fracture was the body of the mandible (n = 137), followed by the angle (n = 114). The majority (83.1%) were treated by closed reduction using intermaxillary fixation, 13.1% by open reduction and internal fixation, and 3.8% had conservative treatment. CONCLUSIONS: Mandibular fractures are commonest during the third decade of life and in men, with almost half of the cases due to of road traffic crashes. RTC was the leading cause of mandibular fractures in all age groups. Motorcycle-related mandibular fractures seem to be increasing in Nigeria. There is a need to enforce legislation designed to prevent RTC to reduce maxillofacial fractures in Nigeria.
