We read the article published by Jaikaran O. et al on ‘Portomesenteric thrombosis after robotic sleeve gastrectomy’ with great interest. The reported about a morbid obese patient having porto-mesentric thrombosis after robotic sleeve gastrectomy due to obesity and mutation in methylenetetrahydrofolate reductase (MTHFR) mutation. However, we have few factors to report on this aspect.
Firstly, MTHFR enzyme dysfunction leads to hyperhomocysteinemia which leads to hypercoagulation state. Yet, the magnitude of this state is affected via degree of enzyme deficiency/dysfunction which is dependent on presence of heterogeneous/ homogenous mutation in enzyme gene. So, the authors must assess for the presence of hyperhomocysteinemia along with assessment of mutation.[1,2] Also the genetic homogeneity of the mutation must be assessed as heterogeneous mutation will have less effect on blood homocysteine levels.[3]
Next, the importance of folic acid for management of thrombotic state due to hyperhomocysteinemia must be considered. The patient has undergone sleeve gastrectomy which may further aggravate her vitamin and micronutrient deficiency. The administration of folic acid (instead of aspirin) will decrease the blood homocysteine levels and reduce the risk of hypercoagulation.[4]

Some more information will make the Case Presentation more Illuminating and Educative, such as:
1) What was Central Venous Pressure,
2) If patient was, presumably Conscious, Oriented, Able to take Food and Fluids by Mouth, could the Intravenous Administration of Fluids be avoided,
3) How did the Elevated Blood Pressure evolved during Hospitalization, either with or without Medications,
4) What was Patient's Diet and Fluid Intake Both Quantitative and Qualitative during the Hospitalization,
5) Whether the Patient took any Formal or Alternative Medicines or Home Remedies for Coryza he had Two Weeks before Episode of Shortness of Breath, that could have caused Autoimmune Hemolysis.

Dear editor,
The case report of published in BMI Case Reports 2020 Oct 29;13(10):e236017 by Ong et al. further expanded the knowledge of cheiro-oral syndrome, an incomplete sensory disorder, in clinical practice. Regarding to the classification of cheiro-oral syndrome, authors cited for Satpute et al. (2013), who clearly described the vascular anatomy of thalamus relating to the clinical picture of sensory and other neurological deficits, including some incomplete sensory syndromes. Bogousslavsky et al. (1988) had reported similar results before. However, to my understanding, the four types of cheiro-oral syndrome was firstly suggested by Chen WH (2009).

To the editor,
The authors of this article appear to be unaware that the cause of "EVALI" was identified almost a year ago. To quote Dr Ann Schuchat, Principal Deputy Director of CDC in December, 2019: "we can conclude that what I call the explosive outbreak of cases of EVALI can be attributed to exposure to THC-containing vaping products that also contained Vitamin E acetate." (1). This followed publication in NEJM of a study which noted that "Vitamin E acetate was identified in BAL fluid obtained from 48 of 51 case patients (94%) in 16 states but not in such fluid obtained from the healthy comparator group." It also noted that "47 of 50 (94%) had detectable tetrahydrocannabinol (THC) or its metabolites in BAL fluid or had reported vaping THC products." It is widely known that people who have become ill due to use of illicit products, such as THC vapes, do not always tell the truth about the illegal products they used. The NEJM study also reported that "9 of 11 patients who reported no use of THC-containing e-cigarette products in the 90 days before the onset of illness had detectable THC or its metabolites in their BAL fluid."

Since the cause became clear in December 2019, identification of new cases of this disease dropped markedly, and in February 2020 CDC stopped reporting new cases. We do a disservice to the public and to our patients by being imprecise about this. EVALI is not caused by nicotine e-cigarettes, just as the epidemic of lethal overdoses associated with addictive pain medication use is not caused by Ibuprofen. We are correct to call that the "opioid epidemic", rather than the "analgesic epidemic". A THC vape is not the same as a nicotine e-cigarette, just as Vicodin is not the same as Tylenol and a joint is not the same as a cigarette. Lets call this serious respiratory disease what it is: THC-Vaping Associated Lung Injury (THCVALI) caused by vaping THC products contaminated by vitamin E acetate. We should inform our at-risk patients and the public tha tit is dangerous to use THC vapes, from the United States that came from informal sources (i.e. not directly from a licensed dispensary or via a doctor's prescription), and we should not confuse our patients or professional colleagues by referring to this illness as if it is caused by nicotine e-cigarettes. It is not. We should therefore call it THCVALI..

Dear Editor,
we found the case report of Banthia et al. extremely interesting. First of all, penile plexiform neurofibromas are quite infrequent. Secondly, the subject described did not have a former clinical diagnosis of neurofibromatosis type I prior to the identification of this tumor, which is even rarer. However, we take exception to the therapeutic approach chosen by the authors. In fact, the surgical treatment of deep and extended plexiform neurofibromas is generally unsatisfactory, since their complete resection is frequently unattainable, allowing the masses to grow back (1-2). A partial tumor debulking should be considered only in case of high-risk conditions, such as a urethral or ureteral compression or a bowel obstruction. Apart from these scenarios, a medical approach should always be preferred, at least as a first attempt.
Selumetinib, an inhibitor of MEK 1 and 2 kinase, has demonstrated to be effective in reducing the size of plexiform neurofibromas in pediatric patients (3-4). The drug is generally well tolerated and safe in the pediatric population. Only few patients failed to show a clinical response to the treatment and even fewer had to stop it due to the appearance of severe adverse events.

Selumetinib, an inhibitor of MEK 1 and 2 kinase, has demonstrated to be effective in reducing the size of plexiform neurofibromas in pediatric patients (3-4). The drug is generally well tolerated and safe in the pediatric population. Only few patients failed to show a clinical response to the treatment and even fewer had to stop it due to the appearance of severe adverse events.
In a recent study, we reported a cohort of nine patients with inoperable plexiform neurofibromas treated with selumetinib (5). Eight of them showed a partial response to the drug, i.e. a reduction of the tumor size by more than 20%. Remarkably, one of them, a five-year-old boy, had a giant plexiform neurofibroma similar to the one described in this clinical case, extended from the abdomen to the pelvis and scrotum. The mass was causing abdominal and scrotal pain, so that the boy couldn’t even sit on a chair. The patient had originally been treated in another institution with a partial debulking procedure, but after twelve months the plexiform neurofibroma grew back to its original size. Furthermore, the surgical excision resulted in the necessity of placing a colostomy, which the boy still has and that will probably be impossible to remove in future, since the plexiform neurofibroma further grew around the distal colic stump. After two years of treatment with selumetinib, a radiological decrease of the mass by more than 20% was noticed, and the boy stopped complaining of abdominal and scrotal pain. Nowadays he’s 10 years old and in good clinical conditions.
In conclusion, we suggest that selumetinib should be preferred to a surgical approach in presence of an extended plexiform neurofibroma, due to the well-known risk or the tumor regrowth after surgery.
The authors describe a single patient who tested positive for SARS-Cov-2 and had sensorineural hearing loss.
In their article they mention that the annual incidence of sudden sensorineural hearing loss (SSNHL) is between 5 and 160 patients per 100,000.
The current population of the UK is 67.866.011 according to the latest data (https://www.worldometers.info/demographics/uk-demographics/, accessed 18th October 2020).
This therefore suggests that there will be between 3,393 and 108,585 patients presenting with SSNHL in the UK this year. Accepting that we have not completed the year we can expect around 80% of the above figures to represent the expected incidence so far i.e. somewhere between 2,714 and 86,868 patients experiencing SSNHL.
The estimated incidence of Covid in the UK population is 0.62%, or 1 in 160 people have so far had Covid.
Therefore, purely by statistics alone, the number of patients with both Covid and SSNHL should lie somewhere between 17 and 543.
Whilst the authors make no claim that in their presented case the Covid was directly responsible for the SSNHL it seems surprising that this article was published by the BMJ as it stands without the authors making any attempt to discern the true incidence of SSNHL in patients with Covid.
Dear Editor:
We read with great interest the case report published by De Silva and Winship1 in the September 2020 issue of this journal. They reported the medical history of a 52-year-old male patient who fulfilled the revised Chompret clinical criteria for Li-Fraumeni syndrome (LFS) and carried a germline CHEK2 mutation (NM_007194.4:c.1100del, p.Thr367fs). The authors highlighted the possible link between CHEK2 germline mutations and a Li-Fraumeni like syndrome phenotype.
The term Li-Fraumeni like syndrome (LFL) was introduced by Birch et al. in 1994 to describe LFS families who did not fulfill the classical LFS criteria, but carried a TP53 germline mutation.2,3 Nevertheless, germline mutations in TP53 gene may not detected in some families with clinical diagnosis of the syndrome. In 1999, Bells et al. reported a family who fulfilled classical LFS criteria and carried a CHEK2 pathogenic mutation, c.1100delC.4 At that time, the authors hypothesized for the first time that heterozygous CHEK2 mutations could be related to LFS phenotype. BRCA2 germline mutations were also described in TP53-negative LFS families.5
Most cancer predisposition syndromes have an autosomal dominant pattern of inheritance with incomplete penetrance and variable clinical expressivity.

Dear Editor:

BRCA2 germline mutations were also described in TP53-negative LFS families.5
Most cancer predisposition syndromes have an autosomal dominant pattern of inheritance with incomplete penetrance and variable clinical expressivity. Genetic and environmental modifiers play a role in intra and interfamilial heterogeneity.8 Environmental modifiers were not mentioned by De Silva and Winship, and should have been described in the case report. Inclusion of environmental risk factors 9 such as tabacco exposure, obesity, sun exposure, alcohol consumption, hypertension could be associated with a higher risk for the multiple primary cancers (clear cell renal cancer, low-grade urothelial tumor, cutaneous basal cell cancer). Furthermore, co-segregation analysis was not performed in affected family members. Her mother, who was diagnosed with a Non-Hodgkin lymphoma at age 47, and her sister, diagnosed with a breast cancer at age 26, were deceased. Nevertheless, her maternal aunt, who developed a pheochromocytoma at age 56 and breast cancer at age 66 was not tested for CHEK2 c.1100delC variant, despite being tested for BRCA1, BRCA2, VHL, MAX, RET, TMEM 127 and SDHx genes.
Differences in CHEK2 penetrance and clinical expressivity may be also modified by polygenic risk and family history (Cybulski et al., 2011; Gallangher et al., 2020). We agree with the authors that more studies are required to translate genetic testing clinical validity to clinical utility, mainly for moderate penetrance genes. Nevertheless, patients who have been diagnosed with LFS and who carry a germline mutation in TP53 gene should undergo high risk surveillance with whole body MRI and genetic testing of minors.6,7 The authors should make clear recommendations that we still don´t have enough data to consider CHEK2 as a causing gene for LFS. There aren´t any indications in this report or any further published data of a higher risk of childhood cancer in CHEK2 carries. Therefore, this information should be evaluated with caution in order to avoid scientific data extrapolation, such as CHEK2 genetic testing for asymptomatic minors, and iatrogenic interventions, such as bilateral mastectomy that is suggested in TP53 mutation carriers and not in CHEK2 mutation carriers (unless strong family history of bilateral breast cancer).
CHEK2 is a moderate penetrance gene that is part of the breast cancer predisposition genes´ family and predisposes also to a higher risk for colorectal cancer. Although patients may carry a higher risk to other cancers, the phenotype is clearly different from high penetrance TP53 carriers, which is the underlying cause of LFS. Cancer predisposition syndromes may share cancer risks, but management clearly differs in carriers of germline mutations in TP53 and CHEK2.
I have read the recent publication in the Journal by Bhattacharyya PJ, et al. BMJ Case Rep 2020;13:e239104. doi:10.1136/bcr-2020-239104 with interest, however I would propose a different interpretation of their case.
The authors present a case of the Takotsubo cardiomyopathy (TC) in a 38 weeks pregnant patient with COVID 19 positive presentation.
They showed that the apical dyskinesis was reversible 2 weeks after her presentation which is one of the features of TC. Nevertheless, the invasive coronary angiography that coincided with the day of the repeat echocardiography (2 weeks after presentation) in my opinion could be in keeping with a revascularized spontaneous coronary artery dissection (SCAD) of the mid LAD, hence the improved flow and recovery of the previously stunned apical left ventricular myocardium. The limited coronary angiographic images show a typical appearance of re-canalising SCAD with the abrupt caliber change of the LAD and the long segments circular and smooth caliber difference indicated by the white arrows on the original image.
It is known that pregnancy predisposes ladies to SCAD and lately we learnt that the COVID-19 inflammatory milieu enhances endothelial vulnerability.
This is an interesting case and the cardiologists and general physicians should all be aware of this type of presentation during COVID 19.
We read the response to our case report published in BMJ case reports " Use of the facial artery-based cutaneous island flap (melo-labial flap) for reconstruction of the neopharynx following total laryngectomy: a novel technique"[1]
We would like to clarify that there is a difference between a new flap and a new technique. A new flap is the one described for the first time in the literature. Contrary to that in a novel technique either a previously described flap or a new flap is used for an indication which has no mention in the literature. Pedicled islanded nasolabial flap have been used in a number of ways and the the cited references by Dr M Alam et al are about its use for floor of mouth reconstruction or for cervical oesophagus for stricture correction. We have also published one such series recently for its versatile use in head neck reconstruction. [2]
To the best of our knowledge it has not been used for a neopharyngeal reconstruction following total laryngectomy and partial pharyngectomy and hence titled as the Novel Technique of neopharyngeal reconstruction.
We refute the statement made by Alam et al in there comment " 5. It is submitted that the rightful credit and recognition belongs to the authors who described the islanded skin flap based on facial vessels in the 1980s. It is not a novel flap christened as DK Gupta flap." and reiterate again that " Use of the facial artery-based cutaneous island flap (mel...

I would like to thank the authors of the interesting case here presented. In some instances, BCC can be devastating. I have seen a case resulting in extenteration of the right eye because of invasion of extra-ocular muscles.
This provides everyone with an opportunity to revise the British Association of Dermatologist (BAD) guidelines for the management of BCC. Lesions of the central face, including the ears, eyes lips and nose, are at a higher risk of recurrence and should be considered higher risk. GPs should have a low threshold for referral or vigilant follow up. As a plastic surgical trainee, I commonly excise these lesions and offer a 6 months review regardless of histological clearance, particularly if the lesion of recurrent.

The authors describe a single patient who tested positive for SARS-Cov-2 and had sensorineural hearing loss.
In their article they mention that the annual incidence of sudden sensorineural hearing loss (SSNHL) is between 5 and 160 patients per 100,000.
The current population of the UK is 67.866.011 according to the latest data (https://www.worldometers.info/demographics/uk-demographics/, accessed 18th October 2020).
This therefore suggests that there will be between 3,393 and 108,585 patients presenting with SSNHL in the UK this year. Accepting that we have not completed the year we can expect around 80% of the above figures to represent the expected incidence so far i.e. somewhere between 2,714 and 86,868 patients experiencing SSNHL.
The estimated incidence of Covid in the UK population is 0.62%, or 1 in 160 people have so far had Covid.
Therefore, purely by statistics alone, the number of patients with both Covid and SSNHL should lie somewhere between 17 and 543.
Whilst the authors make no claim that in their presented case the Covid was directly responsible for the SSNHL it seems surprising that this article was published by the BMJ as it stands without the authors making any attempt to discern the true incidence of SSNHL in patients with Covid.
Dear Editor:
Show MoreWe read with great interest the case report published by De Silva and Winship1 in the September 2020 issue of this journal. They reported the medical history of a 52-year-old male patient who fulfilled the revised Chompret clinical criteria for Li-Fraumeni syndrome (LFS) and carried a germline CHEK2 mutation (NM_007194.4:c.1100del, p.Thr367fs). The authors highlighted the possible link between CHEK2 germline mutations and a Li-Fraumeni like syndrome phenotype.
The term Li-Fraumeni like syndrome (LFL) was introduced by Birch et al. in 1994 to describe LFS families who did not fulfill the classical LFS criteria, but carried a TP53 germline mutation.2,3 Nevertheless, germline mutations in TP53 gene may not detected in some families with clinical diagnosis of the syndrome. In 1999, Bells et al. reported a family who fulfilled classical LFS criteria and carried a CHEK2 pathogenic mutation, c.1100delC.4 At that time, the authors hypothesized for the first time that heterozygous CHEK2 mutations could be related to LFS phenotype. BRCA2 germline mutations were also described in TP53-negative LFS families.5
Most cancer predisposition syndromes have an autosomal dominant pattern of inheritance with incomplete penetrance and variable clinical expressivity. Genetic and environmental modifiers play a role in intra and interfamilial heterogeneity.8 Environmental modifiers were not mentioned by De Silva and Winship, and should have been described in the c...
To the Editor,
I have read the recent publication in the Journal by Bhattacharyya PJ, et al. BMJ Case Rep 2020;13:e239104. doi:10.1136/bcr-2020-239104 with interest, however I would propose a different interpretation of their case.
The authors present a case of the Takotsubo cardiomyopathy (TC) in a 38 weeks pregnant patient with COVID 19 positive presentation.
They showed that the apical dyskinesis was reversible 2 weeks after her presentation which is one of the features of TC. Nevertheless, the invasive coronary angiography that coincided with the day of the repeat echocardiography (2 weeks after presentation) in my opinion could be in keeping with a revascularized spontaneous coronary artery dissection (SCAD) of the mid LAD, hence the improved flow and recovery of the previously stunned apical left ventricular myocardium. The limited coronary angiographic images show a typical appearance of re-canalising SCAD with the abrupt caliber change of the LAD and the long segments circular and smooth caliber difference indicated by the white arrows on the original image.
It is known that pregnancy predisposes ladies to SCAD and lately we learnt that the COVID-19 inflammatory milieu enhances endothelial vulnerability.
This is an interesting case and the cardiologists and general physicians should all be aware of this type of presentation during COVID 19.
We read the response to our case report published in BMJ case reports " Use of the facial artery-based cutaneous island flap (melo-labial flap) for reconstruction of the neopharynx following total laryngectomy: a novel technique"[1]
We would like to clarify that there is a difference between a new flap and a new technique. A new flap is the one described for the first time in the literature. Contrary to that in a novel technique either a previously described flap or a new flap is used for an indication which has no mention in the literature. Pedicled islanded nasolabial flap have been used in a number of ways and the the cited references by Dr M Alam et al are about its use for floor of mouth reconstruction or for cervical oesophagus for stricture correction. We have also published one such series recently for its versatile use in head neck reconstruction. [2]
To the best of our knowledge it has not been used for a neopharyngeal reconstruction following total laryngectomy and partial pharyngectomy and hence titled as the Novel Technique of neopharyngeal reconstruction.
We refute the statement made by Alam et al in there comment " 5. It is submitted that the rightful credit and recognition belongs to the authors who described the islanded skin flap based on facial vessels in the 1980s. It is not a novel flap christened as DK Gupta flap." and reiterate again that " Use of the facial artery-based cutaneous island flap (mel...
Show MoreI would like to thank the authors of the interesting case here presented. In some instances, BCC can be devastating. I have seen a case resulting in extenteration of the right eye because of invasion of extra-ocular muscles.
This provides everyone with an opportunity to revise the British Association of Dermatologist (BAD) guidelines for the management of BCC. Lesions of the central face, including the ears, eyes lips and nose, are at a higher risk of recurrence and should be considered higher risk. GPs should have a low threshold for referral or vigilant follow up. As a plastic surgical trainee, I commonly excise these lesions and offer a 6 months review regardless of histological clearance, particularly if the lesion of recurrent.
