Assessment of multidrug-resistant tuberculosis patient's skin drug reaction in Zanzibar: A certain causal relationship with Clofazimine.

Drug-resistant tuberculosis (DR-TB) is a serious public health of concern. We present the management of multidrug-resistant (MDR)-TB with skin reaction in Zanzibar in a patient who had prior exposure to anti-TB drugs. The reaction developed 4 months later, following MDR-TB treatment, stopped when the drug was withdrawn, and reappeared when reintroduced. Close monitoring is important in managing DR-TB cases, and an active DR-TB safety, monitoring, and management is required to detect, monitor, and manage adverse events timely.

Flap decisions and options in soft tissue coverage of the upper limb.

Soft tissue deficiency in the upper limb is a common presentation following trauma, burns infection and tumour removal. Soft tissue coverage of the upper limb is a challenging problem for reconstructive surgeons to manage. The ultimate choice of soft tissue coverage will depend on the size and site of the wound, complexity of the injury, status of surrounding tissue, exposure of the vital structures and health status of the patient. There are several local cutaneous flaps that provide adequate soft tissue coverage for small sized defects of the hand, forearm and arm. When these flaps are limited in their mobility regional flaps and free flaps can be utilised. Free tissue transfer provides vascularised soft tissue coverage in addition to the transfer of bone, nerve and tendons. Careful consideration of free flap choice, meticulous intraoperative dissection and elevation accompanied by post-operative physiotherapy are required for successful outcomes for the patient. Several free flaps are available for reconstruction in the upper limb including the groin flap, anterolateral flap, radial forearm flap, lateral arm flap and scapular flap. In this review we will provide local, regional and free flap choice options for upper limb reconstruction, highlighting the benefits and challenges of different approaches.

The development and future of reconstructive and microvascular surgery of the hand.

The hand is often thought of as a key discriminator in what makes humans human. The hand is both intricate and fascinating in its design and function, allowing humans to interact with their surroundings, and each other. Due to its use in manipulation of the person's environment, injury to the hand is common. Devastating hand injuries have a profound, physical, psychological, financial and socially crippling effect on patients. Advances in operative techniques and improvements in microscopes and instruments allowed Malt &McKhann to perform the first successful arm replantation in 1962 [1]. This was followed by a myriad of autologous free flaps of varying composition, that were discovered after the mapping of the cutaneous blood circulation by Taylor and Palmer [2] and Mathes & Nahai's classification of muscle flaps [3] providing us with countless options to harvest and transfer healthy, well vascularised tissues into areas of injury. Since the late sixties, with the emerging subspecialty of microvascular reconstruction, surgeons have had the technical ability to salvage many amputated parts, even entire limbs. The measure of functional outcomemust incorporate the evaluation and severity ofthe initial injury and the subsequent reconstructive surgeries [4].

Flap decisions and options in soft tissue coverage of the lower limb.

THE LOWER EXTREMITIES OF THE HUMAN BODY ARE MORE COMMONLY KNOWN AS THE HUMAN LEGS, INCORPORATING: the foot, the lower or anatomical leg, the thigh and the hip or gluteal region. The human lower limb plays a simpler role than that of the upper limb. Whereas the arm allows interaction of the surrounding environment, the legs' primary goals are support and to allow upright ambulation. Essentially, this means that reconstruction of the leg is less complex than that required in restoring functionality of the upper limb. In terms of reconstruction, the primary goals are based on the preservation of life and limb, and the restoration of form and function. This paper aims to review current and past thoughts on reconstruction of the lower limb, discussing in particular the options in terms of soft tissue coverage. This paper does not aim to review the emergency management of open fractures, or the therapy alternatives to chronic wounds or malignancies of the lower limb, but purely assess the requirements that should be reviewed on reconstructing a defect of the lower limb. A summary of flap options are considered, with literature support, in regard to donor and recipient region, particularly as flap coverage is regarded as the cornerstone of soft tissue coverage of the lower limb.

When are circular lesions square? A national clinical education skin lesion audit and study.

BACKGROUND: Skin cancer is the most prevalent cancer by organ type and referral accuracy is vital for diagnosis and management. The British Association of Dermatologists (BAD) and literature highlight the importance of accurate skin lesion examination, diagnosis and educationally-relevant studies. METHODS: We undertook a review of the relevant literature, a national audit of skin lesion description standards and a study of speciality training influences on these descriptions. Questionnaires (n=200), with pictures of a circular and an oval lesion, were distributed to UK dermatology/plastic surgery consultants and speciality trainees (ST), general practitioners (GP), and medical students (MS). The following variables were analysed against a pre-defined 95% inclusion accuracy standard: site, shape, size, skin/colour, and presence of associated scars. RESULTS: There were 250 lesion descriptions provided by 125 consultants, STs, GPs, and MSs. Inclusion accuracy was greatest for consultants over STs (80% vs. 68%; P<0.001), GPs (57%) and MSs (46%) (P<0.0001), for STs over GPs (P<0.010) and MSs (P<0.0001) and for GPs over MSs (P<0.010), all falling below audit standard. Size description accuracy sub-analysis according to circular/oval dimensions was as follows: consultants (94%), GPs (80%), STs (73%), MSs (37%), with the most common error implying a quadrilateral shape (66%). Addressing BAD guidelines and published requirements for more empirical performance data to improve teaching methods, we performed a national audit and studied skin lesion descriptions. To improve diagnostic and referral accuracy for patients, healthcare professionals must strive towards accuracy (a circle is not a square). CONCLUSIONS: We provide supportive evidence that increased speciality training improves this process and propose that greater focus is placed on such training early on during medical training, and maintained throughout clinical practice.

Acute compartment syndrome of the limbs: current concepts and management.

Acute compartment syndrome (ACS) of the limb refers to a constellation of symptoms, which occur following a rise in the pressure inside a limb muscle compartment. A failure or delay in recognising ACS almost invariably results in adverse outcomes for patients. Unrecognised ACS can leave patients with nonviable limbs requiring amputation and can also be life-threatening. Several clinical features indicate ACS. Where diagnosis is unclear there are several techniques for measuring intracompartmental pressure described in this review. As early diagnosis and fasciotomy are known to be the best determinants of good outcomes, it is important that surgeons are aware of the features that make this diagnosis likely. This clinical review discusses current knowledge on the relevant clinical anatomy, aetiology, pathophysiology, risk factors, clinical features, diagnostic procedures and management of an acute presentation of compartment syndrome.

How should we investigate breast implant rupture?

We aimed to examine a cohort of patients presenting with breast implant complications to establish the sensitivity and specificity of clinical examination, Ultrasound Scanning (US) and Magnetic Resonance Imaging (MRI) in the diagnosis of implant rupture, and to examine the correlation between US and MRI. We performed a 26-month retrospective review. Patients underwent US and MRI to exclude rupture. Results of US and MRI were compared prospectively for concordance, then retrospectively to clinical findings and surgical diagnosis. Thirty-four patients with 60 implants were reviewed. The sensitivities of clinical diagnosis, US, and MRI for rupture was 42%, 50%, and 83%, respectively, while the specificities were 50%, 90%, and 90%. The concordance between US and MRI was 87%. MRI is the investigation of choice for implant rupture. US is a valuable alternative with good concordance with MRI. When US is positive for implant rupture an MRI is not necessary to confirm the diagnosis. Knowledge of the sensitivity and specificity as well as the concordance between the two investigations is useful to ensure the appropriate use of available resources.

Hyaluronan, TSG-6, and inter-α-inhibitor in periprosthetic breast capsules: reduced levels of free hyaluronan and TSG-6 expression in contracted capsules.

BACKGROUND: The exact mechanism of capsular contracture (CC) is still unknown. The covalent modification of hyaluronan (HA) with the heavy chains (HC) of inter-α-inhibitor (IαI) has been identified as an important pathway in inflammation and tissue remodeling, where HC·HA formation is catalyzed by TSG-6 (the protein product of tumor necrosis factor stimulated gene-6). OBJECTIVE: The authors quantitatively assess the correlation between severity of CC (measured by Baker grade) and expression of HA, TSG-6, and IαI (ie, the polypeptides HC1, HC2, and bikunin) in periprosthetic breast capsules. METHODS: Immunofluorescent staining for HA, TSG-6, HC1, HC2, and bikunin was carried out on periprosthetic breast capsules (n = 7) of each Baker grade from four anatomical locations. Quantitative analysis was performed to identify differences in staining intensity. Real-time quantitative polymerase chain reaction (RT-qPCR) was performed to determine differences in TSG-6 gene expression levels. RESULTS: Severity of contracture was associated with reduced staining for both free HA (Pearson correlation coefficient, r = -0.645, P < .001) and TSG-6 (r = -0.642, P = .002). RT-qPCR showed a significant negative correlation between severity of contracture and TSG-6 gene expression levels (r = -0.750, P = .001). CONCLUSIONS: The negative correlation between TSG-6 expression levels and severity of CC suggests a possible protective role for TSG-6 in the context of CC formation, and this may have a clinically relevant role in prevention of breast CC.

Cosmetic tourism: public opinion and analysis of information and content available on the Internet.

BACKGROUND: The medical tourism market is a rapidly growing sector fueled by increasing health care costs, longer domestic waiting times, economic recession, and cheaper air travel. OBJECTIVES: The authors investigate public opinion on undergoing cosmetic surgery abroad and then explore the information patients are likely to encounter on the Internet when searching for such services. METHODS: A poll of 197 members of the general public was conducted in the United Kingdom. An Internet search including the terms plastic surgery abroad was conducted, and the first 100 relevant sites were reviewed. RESULTS: Of the 197 respondents, 47% had considered having some form of cosmetic surgery. Most (97%) would consider going abroad for their procedure. The Internet was a source of information for 70%. The review of the first 100 sites under "plastic surgery abroad" revealed that most centers were located in Eastern Europe (26%), South America (14%), and the Far East (11%). Exploring the information provided on the Web sites, we found 37% contained no information regarding procedures. Only 10% of sites contained any information about potential complications. Even less frequently mentioned (4%) were details of aftercare or follow-up procedures. CONCLUSIONS: The authors found that the overwhelming majority of respondents considering plastic surgery would also consider seeking cosmetic surgical treatment abroad. The Internet sites that appear most prominently in an online search contained a distinct lack of information for potential patients, particularly with regard to complications and aftercare. There is, therefore, a need for improved public awareness and education about the considerations inherent in medical tourism. The introduction of more stringent regulations for international centers providing such services should also be considered to help safeguard patients.

When to use drains in breast reduction surgery?

We aimed to identify risk factors that may influence surgeons' decision on the use of surgical drains in breast reduction surgery. Medical notes of 182 patients were reviewed. The mean age of the patients was 38 years and the mean body mass index was 25.4 kg/m. Eighty-three percent of the patients had bilateral breast reduction. The mean weight of the breast tissue excised was 581 g, with the inferior pedicle technique being the most commonly used (52.6%). Factors significantly associated with an increased total drain output were older age (> 50 years, P = 0.001), and larger amount of breast tissue excised (> 500 g, P = 0.004). Neither operative technique nor body mass index influenced the total drain output. We conclude that for patients of over 50 years old and breast reductions of more than 500 g, use of a drain should be considered. Younger patients and breast reductions of < or = 500 g may not benefit from the use of drains.

The contribution of breast and abdominal pannus weight to body mass index: implications for rationing of reduction mammaplasty and abdominoplasty.

The body mass index (BMI) is an arbitrary criterion used by third party fundholders in some countries for rationing the public funding of reduction mammaplasty and abdominoplasty surgery. Many patients have commented that the weight of their excess breast tissue or abdominal pannus contributes to an overestimation of their body mass index. This study seeks to establish the truth of this by ascertaining whether the difference between pre- and postoperative body mass indices of patients undergoing reduction mammaplasty or abdominoplasty is significant. Case notes of 30 sequential reduction mammaplasty patients and 16 abdominoplasty patients were analyzed to ascertain their preoperative weight, height, calculated BMI, and the mass of the breast reduction or abdominal resection specimen as measured in theater. This information was used to retrospectively calculate the difference the weight of the specimen would have made to their BMI. Overall, the difference between pre- and postoperative BMI is not statistically significant (reduction mammaplasty P = 0.22; abdominoplasty P = 0.62, 2-tailed t test). However, the largest contribution breast reduction and abdominoplasty resection specimens made to the BMI in our series was 1 and 2.4, respectively. We suggest that it may be appropriate to consider a minority of patients for surgery if their BMI is within 1.0 (for breast reduction) or 2 (for abdominoplasty) of any set target BMI, and highlight the specific patient subpopulations to which this is most applicable. An estimate of resection weight preoperatively may allow a "corrected" BMI to be used for determining eligibility for surgery.

The pedicled 'policeman' flap salvage of exposed vascular prosthesis - a case report.

A case report of a patient with exposed, infected, subcutaneous, extra-anatomical, vascular prosthesis is presented, which was successfully salvaged using pedicled omental flap after other reconstructive procedures had failed.
