Milk-alkali syndrome was considered "extinct" by 1985 because of the advent of non-alkaline ulcer medications (ie, histamine-2 receptor blockers and proton pump inhibitors). At that time, it was thought to cause <1% of hypercalcemia, which occurred when one ingested a sufficient quantity of calcium and alkali together. This case emphasizes the importance of considering this syndrome in patients who self-medicate for control of symptoms related to gastroesophageal reflux and peptic ulcer disease and for those using calcium supplementation for prevention or treatment of osteoporosis.

Oesophageal spasm is a common empiric diagnosis clinically applied to patients with unexplained chest pain. In contrast it is an uncommon manometric abnormality found in patients presenting with chest pain and/or dysphagia and diagnosed by >or=20% simultaneous oesophageal contractions during standardized motility testing. Using Medline we searched for diagnostic criteria and treatment options for oesophageal spasm. While the aetiology of this condition is unclear, studies suggest the culprit being a defect in the nitric oxide pathway. Well-known radiographic patterns have low sensitivities and specificities to identify intermittent simultaneous contractions. Recognizing that simultaneous contractions may result from gastro-oesophageal reflux this diagnosis should be investigated or treated first. Studies have documented improvements with proton-pump inhibitors, nitrates, calcium-channel blockers and tricyclic antidepressants or serotonin reuptake inhibitors. Small case series reported benefits after botulinium toxin injections, dilatations and myotomies. Uncertainties persist regarding the optimal management of oesophageal spasm and recommendations are based on controlled studies with small numbers of patients or on case series. Acid suppression, muscle relaxants and visceral analgetics should be tried first. Botulinium toxin injections should be reserved for patients who do not respond. Pneumatic dilatations or myotomies represent rather heroic approaches for non-responding patients.

The characteristics of senile osteoporosis are as follows. (1) Bone turnover is not always decrease in senile osteoporosis. (2) Senile patients have urgent fracture risk, such as aging, prevalent fracture(s), low bone mass, and increasing bone turnover. (3) Most of patients are insufficient of calcium and vitamin D. The important things of the treatment for senile osteoporosis with bisphosphonates are (1) to take calcium and vitamin D sufficiently to avoid the excess secretion of parathyroid hormone, (2) to pay attention gastro-esophageal reflux disease, especially the patients with spinal deformity, and (3) to adhere the patient with treatment.

Drinking of sulphate-magnesium-calcium water by patients with gastroesophageal reflux disease of the first degree with cardial manifestations has a prokinetic and anti-inflammatory action leading to attenuation of gastroesophageal reflux and positive cardiovascular changes. Marked therapeutic efficacy of the water is due to specific action of magnesium ions having membrane-stabilizing, sedative effects, pronounced prokinetic and sympatholytic actions which manifest with weakening of ergotropic actions, higher efficacy of cardiac activity. These convert to a noticeable clinical response--regress of clinical symptoms and potentiation of anti-arrhythmic effects.

The enterochromaffin cells of the gastrointestinal (GI) tract secrete 400 times as much melatonin as the pineal gland; therefore, it is not surprising that research is finding that this indole plays an important role in GI functioning. In animal studies, it protects against GI ulcerations, and randomized clinical trials suggest its efficacy in treating functional dyspepsia and irritable bowel syndrome. Melatonin administration has been shown to protect against esophageal lesions in animals. Moreover, in a randomized, single-blind clinical trial of subjects with gastroesophageal reflux disease (GERD), the combination of melatonin with other natural supplements was found to be superior to omeprazole, a proton pump inhibitor (PPI). Its administration as a single treatment for GERD has not been previously reported. A 64-year-old Caucasian female who required treatment with a PPI for symptoms of GERD wished to substitute a natural treatment because of the risk of worsening her osteoporosis. She experienced a return of symptoms following each of three 20-day trials of a proprietary blend of D-limonene when attempts were made to discontinue the PPI. She then underwent a trial of a natural formula consisting of melatonin 6 mg, 5-hydroxytryptophan 100 mg, D,L-methionine 500 mg, betaine 100 mg, L-taurine 50 mg, riboflavin 1.7 mg, vitamin B6 0.8 mg, folic acid 400 microg, and calcium 50 mg. After 40 days, the PPI was withdrawn without a return of symptoms. Subsequently, an attempt to reduce melatonin to 3 mg resulted in symptoms, while all other ingredients were withdrawn with minimal symptoms during 10 months of follow-up.

Osteoclasts degrade bone through the creation of an enclosed, acidic extracellular microenvironment adjacent to the bone surface. Membrane bound proton pumps in the osteoclast cell membrane function to create this acidified environment. Accordingly, this H(+) ion transport mechanism provides a potential target for a specific class of drugs, proton pump inhibitors (PPI), with a view to controlling osteoclast mediated bone resorption. Self setting calcium phosphate cements are common bone graft materials that are degraded by osteoclastic activity. We have already shown that incorporation of bafilomycin, a non-regulated PPI, within these cements prevents or delays osteoclast mediated resorption of the cement. We demonstrate here that two regulated proton pump inhibitors, Pantaprazole and Omeprazole, currently used clinically to treat gastroesophageal reflux disorders, are effective in inhibiting osteoclast mediated resorption in-vivo when delivered to a bony defect in self setting calcium phosphate cements. As determined by qualitative histology, Pantaprazole at a dose of 0.5mg/ml produced a delay in osteoclast resorption whilst this effect was not as evident using Omeprazole at an equivalent dose, but higher doses of Omeprazole (40mg/ml) did delay cement resorption. These data demonstrate, for the first time, the functional effect of blocking the H(+)/K(+) ATPase pump in-vivo on the capacity of osteoclasts to resorb bone and the potential of this strategy to modulate osteoclast mediated resorption of calcium phosphate biomaterials.

NICE recommends immediate referral for patients with dyspepsia and significant acute GI bleeding and urgent specialist referral for investigation if any of the following alarm symptoms are present: progressive difficulty swallowing; chronic GI bleeding; unintentional weight loss; persistent vomiting; abdominal mass; iron deficiency anaemia; suspicious findings on barium meal. Patients aged > 55 with unexplained and persistent dyspepsia, despite H. pylori testing and acid suppression therapy, should also be considered for endoscopy, as should those with previous gastric ulcer or surgery, continuing need for NSAIDs or raised risk of gastric cancer. Patients with uninvestigated dyspepsia should be managed by empirical treatment with a PPI or testing for and treating H. pylori if present. Testing by urea breath test, stool antigen test, or locally validated lab-based serology is suggested. H. pylori eradication is usually given as triple therapy, for seven days, involving a PPI, clarithromycin and either amoxicillin or metronidazole. It is important to take a thorough history and to enquire about any medication the patient is taking. Drugs that are common culprits for dyspepsia include: NSAIDs; calcium antagonists; bisphosphonates; steroids; theophyllines; nitrates. NSAIDs can also cause GI bleeding. Absence of dyspepsia in patients taking NSAIDs does not indicate a reduced risk of bleeding. Peptic ulcers fall into three categories: H. pylori associated ulcers; drug-induced ulcers (particularly NSAIDs); and ulcers in H. pylori-negative patients not taking causative medication. H. pylori is associated with both gastric and duodenal ulcer disease but it is in the duodenum where the closest relationship exists. In any 6-12 month period, 20-40% of healthy people, more commonly men, will experience symptoms of heartburn. Oesophageal reflux can progress to more serious disease such as erosive oesophagitis, stricture or Barrett's oesophagus.

A 51-year-old female patient presented with atypical chest pain, laryngo-oesophageal reflux, increased levels of serum calcium and parathyroid hormone. Ultrasonography showed a multinodular goiter with a prominent solid nodule in the lower left thyroid lobe and a solid hypoechoic nodule outside this area.Tc99m-sestamibi parathyroid scintigraphy was performed to investigate a primary hyperparathyroidism, revealing an area with increased uptake in the lower left thyroid lobe and another area with marked uptake lower than this level. Thyroid scintigraphy with 99mTc showed a cold nodule of the left lower pole. FNA of the thyroid nodule was positive for papillary carcinoma later verified by postoperative histopathology.This case underlines the need for a clinical high index of suspicion for synchronous hyperparathyroidism and thyroid cancer.

The present work describes the formulation and evaluation of the gastroretentive system of Itopride hydrochloride. In this research, we have formulated floating hydrogel-based microspheres employing calcium carbonate (CaCO(3)) as a gas forming agent dispersed in alginate matrix. In vitro characterizations such as drug content, particle size, and drug release were carried out. GI motility was determined by administration of charcoal meal to rats. Results demonstrated that prepared microspheres were spherical in shape with smooth surface, good loading efficiency, and excellent buoyancy. The gastro retentive dosage form of itiopride demonstrated significant antacid, anti-ulcer, and anti-GERD activity after 12 hours in comparison with the conventional dosage form.

Defined pharmacologically by its insensitivity to the GABA(A) antagonist bicuculline and sensitivity to the GABA analogue baclofen, the G protein-linked gamma-aminobutyric acid type B (GABA(B)) receptor couples to adenylyl cyclase, voltage-gated calcium channels, and inwardly-rectifying potassium channels. On the basis of a wealth of preclinical data in conjunction with early clinical observations that baclofen improves symptoms of gastroesophageal reflux disease (GERD), the GABA(B) receptor has been proposed as a therapeutic target for a number of diseases including GERD. Subsequently, there has been a significant effort to develop a peripherally-restricted GABA(B) agonist that is devoid of the central nervous system side effects that are observed with baclofen. In this article we review the in vitro and in vivo pharmacology of the peripherally-restricted GABA(B) receptor agonists and the preclinical and clinical development of lesogaberan (AZD3355, (R)-(3-amino-2-fluoropropyl) phosphinic acid), a potent and predominately peripherally-restricted GABA(B) receptor agonist with a preclinical therapeutic window superior to baclofen.
