Approach to mutilating hand injuries.

Mutilating hand injuries are a challenge to manage due to the complex nature of the injury and the variety of structures that are damaged. Good results can only be achieved by careful planning and management. The ultimate desired outcome is achievement of a normal function of the hand and upper limb. Mutilating hand injuries occur in a variety of settings and the extent of injury and the prognosis varies according to the aetiology of the injury. The management approach focuses on the attention to the repair and reconstruction of individual parts of the hand including the bones, vessels, nerves, tendons and skin cover. Consistent results can be achieved by early aggressive management of damaged structures followed by regular physiotherapy which are the keystones for restoration of form and function of the mutilated hand.

Treatment of deep-seated palatal vascular malformations by bleomycin sclerotherapy.

BACKGROUND: Vascular malformations of the head and neck are common. The management of these lesions is complex and challenging due to the high complication rate and recurrence following treatment. Palatal vascular malformations (PVMs) are infrequent and present as slow growing lesions in the palate with recurrent bleeding and pain. These lesions are best managed by sclerotherapy due to their posterior location and risk of bleeding if surgery is attempted. Many sclerosants have been used for treating PVMs but the use of intralesional bleomycin for these lesions has not been reported at length. This paper describes the use of intralesional bleomycin injections for the treatment of deep-seated palatal vascular malformations. METHODS: Intralesional bleomycin injections were given directly into the lesion with the patients under short general anaesthesia. The total dose of bleomycin ranged between 8 and 15 IU, which depends upon the body weight and was repeated every four weeks till the resolution of lesion was observed. RESULTS: All the lesions in 12 patients regressed significantly with serial bleomycin injections. Clinically, the involved palatal mucosa became normal and magnetic resonance imaging demonstrated the significant regression of the lesion in all the cases. No complications were encountered with the use of intralesional bleomycin. CONCLUSIONS: Intralesional bleomycin injections have proved to be an emerging modality in the management of remotely situated palatal vascular malformations. Their rapid regressive effect on the lesion coupled with a high safety margin makes bleomycin sclerotherapy the first choice of treatment for palatal vascular malformations.

SARS-CoV-2 IgG Surveillance in Asymptomatic Blood Donors and Health Workers.

MATERIALS AND METHODS: 2085 blood donors were allowed to donate blood only after fulfilling all the criteria laid down by the FDA of India with additional history of excluding COVID-19 suspects. IgG antibody testing was performed by chemiluminescence, and results were noted along with their reactive status. Their reactive status was analyzed with donor information to get an idea of the risk parameters for COVID-19. Medical healthcare workers in whom the study was carried out were 560, out of which 114 had worked in COVID-19 duties and 446 had worked in non-COVID-19 emergencies areas. COVID-19 area duties were further subdivided into triage, holding area, isolation, and COVID-19-related duties. The samples were run on architect i2000 and evaluated for their plasma immunoglobulin G. RESULTS: Amongst the asymptomatic blood donors, 1.9% was found to be COVID-19 IgG antibody positive. It was observed that maximum COVID-19 IgG positivity (57.1%) was seen in the age group 18-29 years followed by 26.2% in the age group 30-39 years. Donors in the age group 40-49 years showed antibody positivity of 16.7%, and no antibody-positive donors were found above 50 years of age. COVID-19 IgG positivity was maximum in replacement donors (61.9%) followed by family donors (28.6%) and least involuntary donors (0.6%) Blood donors who showed high IgG positivity were mainly of labor class. Antibody IgG testing on medical healthcare workers showed 2.3% positivity. The healthcare workers who were posted in COVID-19 duties showed 4.8% positivity in the holding area (waiting area with the treatment of patients till their RT PCR report comes) and 5.7% in other COVID-19 areas related to laboratory work. Healthcare workers doing duties in COVID-19 areas showed 2.7% positivity, while those doing duties in non-COVID-19 emergency areas showed a positivity of 2.2%. CONCLUSION: Our study shows that the prevalence of detectable antibodies was low in the general population in India and many patients were asymptomatic as seen in the blood donors, especially the labor class. Maximum exposure was present in young healthy males of labor class who remained asymptomatic. The healthcare workers were more exposed to COVID-19 as compared to the general population probably due to lack of precaution and awareness. Those doing non-COVID-19 duties were also exposed appreciably and needed to take all the precautions required for COVID-19 duties.

Approach to mutilating hand injuries.

Mutilating hand injuries are a challenge to manage due to the complex nature of the injury and the variety of structures that are damaged. Good results can only be achieved by careful planning and meticulous management. The ultimate desired outcome is achievement of a normal function of the hand and upper limb. Mutilating hand injuries occur in a variety of settings and the extent of injury and the prognosis varies according to the aetiology of the injury. The management approach focuses on the attention to the repair and reconstruction of individual parts of the hand including the bones, vessels, nerves, tendons and skin cover. Consistent results can be achieved by early aggressive management of damaged structures followed by regular physiotherapy which are the keystones for restoration of form and function of the mutilated hand.
