Moreau Sources differ, but de la Rosa was supposedly certified by Guinness World Records sometime around as the smallest man on earth. In , de la Rosa died after falling ill, he left behind his wife and their nine year old son. Mohammed is also one of the oldest primordial dwarfs to ever live. In , Mohammed passed at the age of 40, following a heart attack.
Heera, who treated Mohammed for 12 years said that the primordial dwarf suffered from chronic obstructive airway disease, which Mohammed made worse with heavy smoking. Despite being in the Guinness World Record Book for a number of years, Mohammed never capitalized on his fame. He survived on financial help from friends and voluntary organizations after unsuccessfully trying to run a roadside candy stall Mohammed was often robbed because of his small size. Chadra Bahadur Dangi lived to be 75 years old, making him the oldest primordial dwarf in the world.
In , Dangi was recognized by Guinness World Records as the shortest man ever — Dangi was only Before Dangi received his World Record title, he had never set foot outside of his remote village in Nepal. In late , Dangi died at a hospital in America Samoa where he had been admitted a week before after coming down with pneumonia.

There is marked stenosis of the bilateral internal carotid arteries arrows beginning distal to the carotid bifurcation. Additionally, the femoral artery has been a common location for insult, given the catheterizations needed for examination and treatment of associated medical concerns. Three individuals were documented to have femoral artery occlusion after procedures which then necessitated fasciotomies and thrombectomies to treat; however, one went on to need patch and bypass, and after subsequent complications eventually lost the artery and full use of the leg.
Another individual was found to have collapse of a superficial femoral artery, treated by bypass; later noted to have thrombosis with subsequent restenosis and revision. An additional individual was noted to have a femoral artery pseudoaneurysm, treated by thrombin injection.
Lastly, yet another individual had focal severe stenosis identified in the common iliac artery, leading to stent placement, and subsequent in-stent restenosis. In addition to recommended lifestyle intervention e. In addition, central alpha agonists e. Criteria for diagnosing hypertension was not always consistent among the population. It is evident that anti-hypertensive therapy was not always started when a patient met criteria for hypertension, suggestive of therapeutic inertia in this population.
Given the sporadic and sometimes incomplete nature of data received from some individuals, we are unable to report by percentile according to height, so instead tabulated data by the pressures themselves. According to Flynn et al. A majority of individuals in each blood pressure range had an elevated measurement recorded on at least 3 separate occasions.
As Fig. Table 2 delineates the frequency of other comorbidities in the total cohort, as well as ages at diagnosis when known. The two not noted to be under treatment were the youngest, with hypercholesterolemia detected at 5 and 6 years of age. Mean diagnostic age of insulin resistance was 12 years, and mean age of type II diabetes diagnosis was 14 years of age. Our primordial registry was conceived over a decade ago out of the hope from many families with MOPDII, that by gathering data together, we would be able to better understand why there did not seem to be any older adults with this diagnosis.
Hall et al. Now, about a decade and a half later, MOPDII neurovascular screening guidelines have been more precisely honed, with screening starting at diagnosis [ 4 , 14 , 24 ]. The questionnaire for our MOPDII vascular substudy was complicated, given the details needed to make this review as robust as possible, and the medical complexity of this condition for some individuals. A few of the families who did not complete the survey likely did not because they were clinic patients of ours, and we already are well-versed in their clinical course.
However, there were also rather medically involved individuals for whom we were left with minimal information. However, we posit that the data that remains is still the most comprehensive compendium of its kind for individuals with MOPDII. Through presymptomatic screening as well as with imaging performed after clinical signs present, our data demonstrate that about two thirds of individuals developed neurovascular disease, with half of all individuals developing intracranial aneurysms, approximately half identified with moyamoya, and a third with both diagnosed Table 2.
Our results also underscore that moyamoya presents at younger ages than aneurysmal disease Fig. Surgical outcomes for revascularization surgery and aneurysm treatment in MOPDII have been previously described [ 16 ]. In our relatively large cohort of an exceedingly rare disease, renal artery stenosis, renal aneurysms, carotid and coronary artery disease were noted.
Therefore, cardiac and renal screening appears warranted in this population. Although, the precise nature and frequency of screening is not yet fully developed. This association is additionally noted in the general population. There have also been published cases of individuals with moyamoya and peripheral pulmonary artery stenosis with post-stenotic aneurysms [ 30 ]. Diabetes and insulin resistance are additional important contributing factors, with over a third of individuals in our cohort with one of those diagnoses.
These alone are associated with both microvascular and macrovascular disease, leading to endothelial dysfunction, smooth muscle cell dysfunction, and platelet dysfunction, with coronary artery disease as the most common cause of death for people with type 2 diabetes [ 9 , 34 ]. Since dyslipidemia and hypertension are also associated with type 2 diabetes [ 23 , 34 ], screening of these would also be important for individuals with MOPDII, as they all contribute to cardiovascular complications [ 9 ].
Fourteen individuals in this cohort trialed human growth hormone replacement. Some stopped after a few months, and others continued for years. While true that eight other individuals developed insulin resistance in the absence of growth hormone supplementation, given the published added risks and inefficacy of this treatment [ 9 ], would recommend not pursuing growth hormone treatment in this condition.
For the individuals with MOPDII in this study, chronic kidney disease CKD appeared independent from renal vascular disease, and is at a frequency that warrants screening as well. CKD itself is associated with a high risk of coronary artery disease, with an elevated risk of cardiovascular mortality beyond that associated with often concomitant hypertension and diabetes [ 35 ]. Of our cohort, there were only 3 individuals who were treated for hypertension but were not diagnosed with moyamoya or intracranial aneurysms; two of these three were diagnosed with stage IV CKD and are now deceased.
CKD is also known to modify the presentation of coronary artery disease and myocardial infarctions, such that one needs to be critical of atypical symptoms [ 35 ]. This is all the more crucial information for individuals with MOPDII, as the current study has documented heart attacks occurring in young adulthood for multiple individuals. Emergency providers need to be at high alert for this possibility so that appropriate treatment can be initiated promptly in an acute situation.
In our MOPDII cohort, approximately half of all the individuals have been diagnosed with hypertension or pre-hypertension. These are not insignificant numbers, and as we posit above, the true proportions are possibly higher than this since providers are likely under-diagnosing hypertension in this population.
There are recommendations to monitor blood pressure in MOPDII [ 7 , 12 , 15 ], though normal ranges for individuals with this degree of extreme short stature have never been delineated. Using typical sex and age-related norms for individuals who have short stature can lead to misclassification of hypertension as normal [ 36 ]. It has been hypothesized that chronic increased pressure of even a moderate amount could be proportionally more damaging to smaller vessels and organs, and that chronic hemodynamic stress on abnormal vessels could drive cerebral aneurysms [ 7 , 14 , 15 , 24 , 37 , 38 ].
It is additionally problematic to modulate blood pressure in individuals with risk of both moyamoya and aneurysms. Anesthesia can be tenuous in these scenarios, as one cannot drop the pressure too low or let it get too high without risk of ischemic or hemorrhagic strokes [ 15 , 39 , 40 ]. The difficulty in monitoring and treatment of hypertension in those with extreme short stature along with a risk of neurovascular disease is — what should the top systolic and diastolic pressures be?
Besides not knowing the hypertensive range for this population, the difficulty in monitoring is compounded by the challenge of getting an accurate measurement on individuals with such small and slender limbs; oftentimes a neonatal cuff is needed for school age children and younger with MOPDII. This is an area that needs further in-depth study. We provide this only as a starting point, as we implore medical providers to be aware of the complexities involved for this population.
Untreated hypertension can have catastrophic effects at young ages for those with MOPDII, so should be monitored closely. Also, it is important to not overlook that acute hypertension should be investigated by imaging before treatment, because the etiology could be neurovascular disease or vascular disease elsewhere.
As there are so many variables involved, it may be too difficult to completely tease things out at this juncture. A majority of the individuals who had myocardial infarctions as young adults had moyamoya diagnosed as teenagers or later, and did not have neurovascular imaging to screen starting in infancy as many children now do. This group of individuals likely had chronic hypertension for years without identification and treatment, which certainly could contribute to all the subsequent sequelae of medical complications that are now evident.
Children with MOPDII entering adolescence right now may have a different natural history of disease, as one variable should be eliminated if they have had access to brain MRA or CTA modalities at birth and onward, given the recommendations for neurovasculature screening starting at diagnosis for moyamoya and aneurysms published a decade ago.
However, even if neurovascular disease could be detected presymptomatically, and fully treated without sequelae, that is likely not the end of the story as there are multiple people with MOPDII who have had coronary artery disease or chronic kidney disease along with normal neurovascular screens.
As the registry has been in existence for over 10 years, many families had consented into the original project, but had stopped proactively sending medical records into the repository.
Updated consents would be signed over the years, to allow us to reach out to their treating physicians for records as needed. There were some individuals that died between enrollment in the registry and this substudy. Given the nature of this project, those would be the most important records to identify and obtain. However, considering the sensitive nature of the circumstance, multiple of these families were either not responding to our inquiry, or once contacted, were not interested in participating in the survey or providing updated record releases.
For these families we are only aware tangentially of what occurred for their child, which was not included in the larger analysis because the finer details could not be obtained.
This data underscores the high burden of vascular concerns in this population. Though screening regimes have been published and put in place worldwide for neurovascular issues such as moyamoya and intracranial aneurysms, there are no evidence-based guidelines for screening for the other vascular manifestations.
There has also not yet been a focused study on hypertension in this population, which would be an important avenue for further research. This interval was chosen following the observation of a child progress from a normal MRI to stroke in a 2 year period of time. If moyamoya is detected and treatment is initiated, we believe that further monitoring for moyamoya be done at the discretion of the treating physician.
Screening for aneurysms, however, should continue despite identification and treatment of moyamoya, due to continued risk of development of aneurysms into adulthood; screening should be at least every 2 years after the age of 18 [ 7 ]. Due to structural abnormalities noted above, recommend renal ultrasound at diagnosis. Also, because chronic kidney disease appears independent from renal vascular disease, recommend assessments of renal function starting at age 5 [ 7 ].
The most precise way to monitor renal function and glomerular filtration rates is not clear, but looking only for elevated creatinine levels will prove inadequate given the stature and lean muscle mass of this population.
Nephrologists following this cohort have used testing such as cystatin c level and inulin clearance to assess and monitor glomerular filtration rates. Additionally, because kidney stones were noted in individuals on antihypertensive medicines, would recommend monitoring for that complication as well for individuals in that situation. Given structural abnormalities noted, echocardiogram is recommended at diagnosis. Blood pressure should be monitored annually [ 7 ], with a cuff of appropriate size.
For children, the height equivalent 95th percentile pressure limits from Flynn, et al. Consideration should be given to the use of echocardiogram and ECG for signs of hypertension as well. Although blood pressure measurements should begin at diagnosis and continue during routine check-ups, if non-elevated pressures are found, the referral to subspecialists can likely be deferred until 5—10 years of age.
If elevated blood pressures are noted, and before hypertension is treated with medication, due diligence should be performed to rule out the many possible etiologies associated with MOPDII, specifically moyamoya disease as well as renal artery stenosis. Hypercholesterolemia is another comorbidity which should be screened for and treated appropriately once detected.
Though not specifically studied here, lifestyle interventions associated with lower blood pressure could certainly be considered to minimize other contributing factors, to include: DASH diet, avoidance of high sodium foods, physical activity, and weight management [ 23 ].
It cannot be underscored enough that any signs of myocardial infarction atypical or otherwise should be taken seriously, given the relatively high incidence at a young age in this population. Additionally, when performing any needed catheterizations, extreme care should be taken, given the known postoperative complications with femoral artery stenosis.
Given the additional negative impact of diabetes for individuals with already a high risk of cardiovascular disease, recommend screening to begin at age 5 years, to ensure it is identified and treated at the earliest stage [ 9 ]. Laboratory studies for insulin resistance should include studies of lipids, hepatic function, and glucose homeostasis [ 7 ].
A majority of the authors of this study have been involved with the national support group for primordial dwarfism for many years. We have been thrilled to see neurovascular screening protocols appear to save lives, to then witness with a heavy heart young adults succumbing to other unanticipated maladies. Knowing the landscape is one thing, and knowing how to navigate it is another. We are optimistic this survey is the first step in helping to unravel the key to best take care of individuals with MOPDII.

Christy Jordan, 44, a registered nurse, has raised her children to believe they can do anything. A single mom, she relies on a large extended family of aunts and uncles and cousins.
With their sister Brandi, who calls herself the "outcast" for being taller, they go camping and take trips to Las Vegas and help around the house. In the past, dwarfs have often been portrayed in circus sideshows or in comical roles on television and the movies.
But today, there are more role models in entertainment. Christy Jordan said she isn't even critical of the entertainment shows that highlight dwarfs in comedic roles [Danny Woodburn of "Seinfeld" and Verne Troyer of the "Austin Powers," for example] -- "as long as it is done tastefully and they are not exploited.
He hopes to go on and work in sports or the theater arts. She wants to he a fashion designer and create clothing for little people. To learn more go to the Potential Foundation, which supports the work of families dealing with dwarfism.
