Abstract
This 31-year-old white male with heartburn and dysphagia unresponsive to antacids was diagnosed with eosinophilic esophagitis. He finds relief of his symptoms by using cannabidiol rich concentrates.
Patient information
Gender
Male
Age
25-34
Brief history and target symptomatology
This 31-year-old computer security specialist developed heartburn around age 15, which did not respond to usual antacid treatment. 6 years later he developed severe dysphagia and was diagnosed with eosinophilic esophagitis upon esophagoscopy and biopsy. Recently he required bougienage for esophageal stricture. Cannabidiol rich concentrates relieve his dysphagia, without the need for additional medication.
Previous and current conventional therapies
Standard antacid therapy (Protonix, Nexium) did not relieve heartburn. He undergoes annual esophagoscopy and esophageal biopsy and recently required esophageal dilatation for stricture. He is currently in remission, for which he credits cannabidiol.
Clinical response to Cannabis
Relief of heartburn and dysphagia.
Additional Comments
Esophageal eosinophilia is increasingly recognized as a separate disease, with an incidence of one in 10,000 per year. Unlike GERD, it does not respond to antacids. It manifests with progressive dysphagia and may progress to esophageal stricture. It is usually associated with food allergies, however it may occur in antibody deficient patients. It is treated with dietary restrictions and topical corticosteroids, such as Flonase. The role of medical marijuana has not been investigated.

Here is a description of patient's method of using medical marijuana: “I do not use medical marijuana throughout the day, just at night, usually sometimes just before dinner to before bed, but almost never more than once in a day. I have used it twice after food has become lodged (and subsequently dislodged) to try to limit the additional swelling that usually occurs after such an event. With the use of medical marijuana, I have been able to return to, and finish my meal. My tolerance is quite low, so I have tried both vaporized plant and concentrate, and smoked plant, and low-dose lozenges and sprays. I cannot say for certain that one is any better than the other; all seem to help.”

Abstract
A 37 y/o PhD university research associate with retinitis pigmentosa found relief of associated symptoms with cannabis and subjective slowdown in progression of vision loss.
Patient information
Gender
Male
Age
35-44
Brief history and target symptomatology
This 37 y/o PhD university research associate was diagnosed with retinitis pigmentosa (RP) at age 14. He experiences progressive vision loss, headaches, depression and insomnia.
Previous and current conventional therapies
Supplementation with antioxidant vitamins was ineffective. Serial electroretinopathies (ERG) were discontinued in the belief that the flashes of light used further damage his retina and "ophthalmologists only want photographs for their own collection". His eyeglass prescription is reviewed annually to compensate for his increasing tunnel vision. He has not found significant improvement in his mood with psychotherapy.
Clinical response to Cannabis
Stress, mood, headaches and insomnia have all improved with cannabis use.
Additional Comments
RP is a genetic disease found in 1 in 4000 people in the US. In patient's case, it was traced to mutations in both parents' X chromosome. There is no known cure; valproic acid, gene therapy and retinal transplantation are currently in the research stage. Administration of a THC analog to rats with chemically induced RP has shown reduction in the rate of degeneration of retinal photoreceptors. .

Medical Condition:Glaucoma

Comorbidities

Congenital cataracts
Medical Condition
Glaucoma
Symptoms
Vision loss, eye pain, tearing.
Abstract
This 58-year-old patient was born with bilateral cataracts. He had surgery on one eye at age 3. Eventually he developed near blindness in that eye and severe vision loss in the other. He suffers from constant eye discomfort, frequent headaches and tearing. He uses edible marijuana for prolonged mydriasis, which improves his vision and relieves his other symptoms.
Patient information
Gender
Male
Age
55-64
Brief history and target symptomatology
This 58 years old man was born with bilateral cataracts. At age 3 he underwent surgery on his left eye, suffered postoperative complications and progressive loss of vision; he developed retinal detachment, then glaucoma and became legally blind in this eye around age 35. His right eye was not operated on but also suffered progressive loss of vision with a visual acuity of 20/80 currently.
The patient was a software programmer for several years however his deteriorating vision forced him to switch from actual programming to a consulting role. He uses on occasion the common mydriatic agent Cyclogyl to maximally dilate his pupils, allowing him his best possible vision but prefers edible marijuana because its effect is longer-lasting. Marijuana also relieves a constant discomfort associated with his vision, which he calls "eyestrain" and which may progress to frank headache.
Previous and current conventional therapies
Surgery. Mydriasis with Cyclogyl (generic name: cyclopentate HCl).
Clinical response to Cannabis
Improved vision. Relief of associated "eyestrain" and headaches.
Additional Comments
Congenital lenticular opacities (cataracts) are rare, estimated at 5 per 10,000 in the US. Most are idiopathic, many are familial, some are due to intrauterine infections or metabolic and genetic disorders. Visually significant cataracts are in the center of the visual axis and greater than 3 mm in diameter. For these, surgery is the treatment of choice; outcomes have improved over the years with the development of new techniques and new intraocular lenses (although use of the latter in infants remains controversial). To ensure minimal or no visual deprivation, surgery should be performed when patients are younger than 4 months. Even with aggressive surgical and optical treatment, visual deficits are common: amblyopia ("lazy eye"), nystagmus and strabismus in childhood, and glaucoma and retinal detachment years after surgery.

Age
35-44
Brief history and target symptomatology
The patient drove a cab for 39 years and retired 2 years ago. He has suffered from psoriasis for 16 years and currently takes IV Orencia w. maltose ( generic: Abatacept) for severe hand pain due to psoriatic arthritis. He was a longtime tobacco smoker until 2010 when he was diagnosed with right tonsillar cancer and treated with radiation and long-term chemotherapy. He now suffers from dry mouth and decreased appetite. He spends a long time flossing and brushing his teeth after every meal to decrease his risk of dental caries. He does not suffer from xerostomia and does not have Sjogren's syndrome to his knowledge.
Previous and current conventional therapies
Cough lozenges were not effective.
Clinical response to Cannabis
Marijuana subjectively decreases the unpleasant feeling of dry mouth and subjectively increases his production of saliva. It also "definitely" improves his appetite.

Abstract
Proctalgia fugax is a recurrent episodic form of a more prolonged and severe condition called levator ani syndrome. It is associated with often excruciating rectal pain and great difficulty defecating. It involves the internal anal sphincter and may represent neuralgia of the pudendal nerves. It has no known cure.
Patient information

Male
Age
25-34
Brief history and target symptomatology
The patient is a 26-year-old experienced computer specialist, fully and stressfully employed as a customer assistant in a retail electronics store. His rectal pain may occur at night or during the day, when it causes significant social anxiety.
Previous and current conventional therapies
Warm baths (if the pain lasts long enough to draw a bath), warm enemas, relaxation techniques. (Botulinum toxin, inhaled Albuterol and low dose diazepam at bedtime have been mentioned in the literature as occasionally helpful but the patient has not tried these.)
Clinical response to Cannabis
Inhaled marijuana brings immediate relief of the acute symptoms. Regular marijuana use somewhat decreases the frequency of pain attacks.

Brief history and target symptomatology
This child was diagnosed at 6 years of age with neuroblastoma. He was having pain, nausea, and vomiting at the onset of the disease.
Previous and current conventional therapies
Chemotherapy, Surgical de-bulking tumor resections, Radiation therapy, Intra-operative radiation therapy.
Clinical response to Cannabis
Gastrostomy tube feedings followed by intravenous hyperalimentation feedings were utilized to support nutritional status. Parents consulted Dr. Mikuriya for a cannabis approval when child was dying at age 9. Pain control and control of nausea and vomiting followed onset of regular cannabis use. Cannabis use was typically smoked for rapid onset and ease of dosage control. Frequency of use was symptom dependent and variable, though typically once or more daily
Additional Comments
After 4 years of regular cannabis use and no further conventional therapies from the University based treatment program, there was no longer any evidence of the neuroblastoma tumors. He continued to use cannabis on a daily basis for control of pain, nausea, and anorexia until he was 16 years of age. Sadly, he died at age 16 with peritonitis/sepsis from a perforated bowel.

Patient information
Gender
Female
Age
45-54
Brief history and target symptomatology
Four year h/o metastatic breast cancer, in liver failure and within 4 days of dying. Had a history of anxiety disorder well managed by occasional benzodiazepines. Was not a cannabis user previous to chemotherapy; resistant to using during chemotherapy. Did not like the ‘wooziness’ side effects. Agitated, restless, and anxious about the rapidity of her demise.
Previous and current conventional therapies
Ativan (lorazepam), liquid morphine.
Tried THC cannabis and did not like side effects during chemo.
Tried CBD-Rich cannabis and reported rapid and complete relief from chemotherapy side effects (nausea, dizziness, GI pain and anxiety).
Clinical response to Cannabis
Given CBD-Rich cannabis in honey-butter edible mode of administration. After first dose of CBD butter did not require any more lorazepam. Was able to communicate her needs and rest without side effects.
Additional Comments
She ran out of the CBD butter and her caregivers attempted to give her THC butter. After a single dose she refused any more, saying that it made her woozy. CBD was obtained and was sufficient until she died.

Abstract
A 21-year-old college student with systemic mastocytosis uses inhaled medical marijuana to relieve symptoms and gain homeostasis.
Patient information
Gender
Male
Age
18-24
Brief history and target symptomatology
Beginning in his teen years, this young man has had urticaria pigmentosa, allergy to multiple foods and food preservatives resulting in frequent flareups of abdominal pain, nausea, vomiting or diarrhea. Sunny, cold or hot weather could cause generalized arthralgia.
Previous and current conventional therapies
The patient still takes Gastrocrom (Cromolyn, a mast cell stabilizer) but believes that medical marijuana is the most important factor in his well-being. He carries with him at all times injectable epinephrine in case of anaphylactic reaction.
Clinical response to Cannabis
The patient's most frequent symptom is sudden bouts of gastrointestinal distress (pain, nausea, diarrhea). For the past 2 1/2 years, since he started using medical marijuana, he has had few flareups, when carefully avoiding known food allergens and other precipitants.
Additional Comments
This patient most likely suffers from the indolent subtype of systemic mastocytosis. The pathologic manifestations of this disease are the abnormal accumulation of mast cells in the skin, G.I. tract, bone marrow, and lymph nodes and the frequent association with hematologic disorders. A genetic (proto-oncogene c-KIT) mutation is usually detectable in the mast cells and their precursors. Symptoms are due to the release from mast cells of leukotrienes which are responsible for contraction of smooth muscles, stimulation of vascular permeability, and attraction and activation of leukocytes; these are three to four orders of magnitude more potent than histamine. Counseling, prevention of exposure to mast cell secretory stimuli and symptomatic treatment are the mainstays of current patient management.

Abstract
46 year old male carpenter with slowly progressing Dupuytren's contacture of his right 3rd finger was advised to try using a home made concentrated cannabis salve with an occlusive barrier (nitrile glove) at bedtime in order to reduce daytime pain. Patient returned one year later for his medical cannabis recommendation withnear complete resolution of the contracture.
Patient information
Gender
Male
Age
45-54
Brief history and target symptomatology
Several year progression of palmar fascia and flexor tendon contracture of the right third finger was making it more and more difficult for this patient to swing a hammer on the job. He was looking for a non-psychoative alternative for daytime pain relief. Exam found a classic thickened and deformed palmar fascia with firm bead deformities of the flexor tendon.
Previous and current conventional therapies
Massage, splinting.
Clinical response to Cannabis
Within several weeks of bedtime cannabis salve and a glove the contracture had nearly entirely resolved.
Additional Comments
Dupuytre's contractures may in part be due to upregulation of myofibroblasts. The endocannabinoid system has been described as a mediator of mesenchymal stromal cell immunosuppressive properties. http://www.ncbi.nlm.nih.gov/pubmed/24312195
