Pericardial effusion as a complication of chronic graft versus host disease

A 24-year-old man with previous matched unrelated donor allogenic bone marrow transplant for aplastic anaemia and chronic graft versus host disease on steroid taper presented with progressively worsening anasarca. CT revealed large pericardial effusion, while echocardiogram was concerning for early tamponade physiology. He underwent emergent pericardiocentesis with pericardial drain placement. Extensive rheumatological and infectious work-up was unrevealing with patient's presentation attributed to pericardial graft versus host disease. This highlights the need of physicians to be aware of pericardial serositis as a complication of graft versus host disease due to its life-threatening complications, which require immediate intervention.

Potassium chloride mixture may maintain hypokalaemia and hypertension

Hypokalaemia can be treated with potassium chloride mixture. Some mixtures contain liquorice extract (glycyrrhizin) as a supplement to improve taste. Glycyrrhizin can cause pseudohyperaldosteronism and thereby result in hypertension and hypokalaemia. We here present a case where treatment with potassium chloride mixture causes hypertension and hypokalaemia in a 50-year-old woman. After unravelling differential diagnosis, the potassium chloride mixture was stopped. After the discontinuation, the patient's blood pressure was well managed and the potassium levels normalised.

Catatonia due to alprazolam withdrawal

A 50-year-old man with multiple psychiatric comorbidities including major depressive disorder and general anxiety disorder presented to the emergency room (ER) with altered mental status, immobility and mutism. The patient was unresponsive to commands and unable to provide any history. In the ER he was given a provisional diagnosis of cerebrovascular accident (CVA). Vital signs on admission were stable. On physical examination, he exhibited grimacing, muscle rigidity and areflexia. Workup for CVA and infectious aetiology was unremarkable and the patient's urine toxicology screen was negative. History from the patient's family revealed that 4 days prior to presentation, the patient had discontinued his prescribed dose of alprazolam 1 mg four times per day. The patient was diagnosed with catatonia due to benzodiazepine withdrawal and had gradual return to baseline with administration of lorazepam 1 mg intravenous three times per day.

Renal sarcoidosis: a rare case

Sarcoidosis is a multisystemic granulomatous disease with rare renal involvement. We describe a case of a 45-year-old female patient admitted to the hospital with severe acute kidney injury and uveitis. After clinical investigation, sarcoidosis with renal, hepatic and ocular involvement was diagnosed. Renal biopsy revealed acute granulomatous interstitial nephritis and treatment with systemic corticosteroids was started with marked improvement in renal function.

Dexmedetomidine-assisted drug interviews: an observation in psychiatric setting

Drug-assisted interviews are an effective tool in the management of various psychiatric illnesses where psychopharmacological, as well as routine psychological interventions, do not prove beneficial. These have most commonly been done by using barbiturates and benzodiazepines that have given favourable results for a long time. However, they carry the risk of respiratory depression and difficulty in maintaining the plane of sedation where the patient is amenable to interviewing. In our experience of drug-assisted interviews with two patients we used intravenous dexmedetomidine, which is being used in anaesthesia practice for conscious sedation or sedation in the intensive care unit. We found dexmedetomidine to be superior to thiopentone in achieving a level of conscious sedation where the patients were amenable for an interview, with no significant adverse events and faster post-anaesthetic recovery.

Single right coronary artery with congenital absence of left coronary system

Single coronary artery (SCA) is a very rare coronary anomaly. The accurate diagnosis of the entity requires multimodality imaging of the coronary anatomy. SCA is often incidentally diagnosed when patients are investigated for symptoms of suspected coronary artery disease with invasive or non-invasive coronary angiography. There are no established diagnostic electrocardiographic or echocardiographic criteria to identify the presence of SCA, which makes the diagnosis a far-reaching fruit. We present a young male patient presenting with a non-ST elevation myocardial infarction. He was found to have SCA on invasive coronary angiography, which was subsequently confirmed by CT coronary angiography.

Haemostatic radiation therapy for a bleeding intraductal papillary neoplasm of the biliary tree

Haemostatic radiation was effectively used as a novel rescue therapy in a 60-year-old man who presented with recurrent melaena refractory to all conventional medical and surgical measures. He needed multiple transfusions and was diagnosed to be bleeding from an intraductal papillary biliary neoplasm which was not amenable to surgical resection in view of the background liver disease. He received conventional radiation therapy (RT) of a dose of 3 Gy per fraction for 3 consecutive days after which he stabilised. After cessation of the RT, he did not require transfusion for the next 2 months. His quality of life improved and it gave us time to evaluate for other definitive measures.

Thyroid storm: a case of haemodynamic failure promptly reversed by aggressive medical therapy with antithyroid agents and steroid pulse

Hyperthyroidism is a common metabolic disorder, although its presentation as an endocrine emergency called thyroid storm is rare. Here we review a case of a thyroid storm as the initial presentation of thyrotoxicosis, with multiple organ failure and haemodynamic collapse due to low-output cardiac dysfunction. Quick intervention with aggressive antithyroid therapy, including steroid pulse, and supportive intensive care measures led to an outstanding improvement and full recovery. The present case clearly shows the beneficial impact of initial clinical suspicion resulting in an early diagnosis and intensive therapy. Moreover, it supports the additional role of steroids to aggressive antithyroid strategy in order to control associated deleterious systemic inflammatory reactions.

Metastatic adenocarcinoma of mandible: in search of the primary

We present here a case of a 64-year-old female patient who reported with a complaint of pain in the chin region of 3-month duration. The radiographs revealed an irregular radiolucent lesion in the anterior part of the mandible. An incisional biopsy was carried out and the microscopy showed features of adenocarcinoma. Suspecting a metastatic lesion, the patient was then sent for whole body examination which showed a mass in the lungs. A whole body scan also showed metastasis to other organs such as kidney, gallbladder and vertebrae. This case is unusual in that the patient complained only of a vague jaw pain with no other systemic symptoms even in the presence of widespread disease.

Late onset of dropped head syndrome following mantle radiation therapy for Hodgkin lymphoma

Dropped head syndrome (DHS) is a rare condition, characterised by weakness of the cervical paraspinal muscles with sagging of the head. It is usually seen in association with neurological disorders and rarely can follow radiotherapy. We report a case of a 54-year-old man survivor of Hodgkin lymphoma (HL), who developed DHS 28 years after radiotherapy. He was referred to our department due to progressive weakness and atrophy of cervical paraspinal and shoulder girdle musculature. Physical and neurophysiological examination, electromyography and MRI confirmed the diagnosis of DHS. In the following years, there was no progression of symptoms.

Anaphylaxis after treatment with recombinant factor VIII: investigation and therapeutic challenge

We report a 10-year-old patient with haemophilia A developing anaphylaxis to recombinant factor VIII (octocog alfa). Allergic reactions, and especially anaphylactic events, are rare in patients with haemophilia A. The nature of these reactions is not fully understood. Here, we demonstrate a type I hypersensitivity reaction using sodium dodecyl sulfate-polyacrylamide gel electrophoresis immunoblotting assay. This test revealed itself as an essential diagnostic tool, as it allowed us to choose an alternative treatment (moroctocog alfa). Its safety was later confirmed by an uneventful challenge test.

Exogenous steroid-induced hypoadrenalism in a person living with HIV caused by a drug-drug interaction between cobicistat and intrabursal triamcinolone

We report a diagnosis of exogenous steroid-induced hypoadrenalism in a person living with HIV caused by a drug–drug interaction (DDI) between intrabursal triamcinolone and the pharmacokinetic booster cobicistat. A 53-year-old woman living with HIV, managed with dolutegravir and cobicistat-boosted darunavir, presented to the orthopaedic clinic with worsening hip pain. She was diagnosed with greater trochanteric pain syndrome (GTPS) of the hip and was treated with intrabursal injection of bupivacaine and triamcinolone. Seven days following this injection, she presented with Cushingoid features, an undetectable cortisol and was diagnosed with exogenous steroid-induced hypoadrenalism. Cobicistat is a cytochrome P450 3A inhibitor and in this case inhibited clearance of intrabursal triamcinolone, leading to exogenous glucocorticoid excess and adrenal suppression. This is the first report to describe this predictable DDI with cobicistat following intrabursal glucocorticoid injection. This case highlights the complexities in managing non-HIV-related chronic morbidities in people living with HIV.

Giant juvenile papillomatosis of the breast in a Nigerian girl

Juvenile papillomatosis is a benign epithelial proliferative tumour of young women. It was recognised as a distinct clinicopathological entity with defining criteria by Rosen et al since 1980. However, giant juvenile papillomatosis is rare. We report a case of a 14-year-old girl who presented to our institution's breast clinic with a huge right breast mass measuring 20 cm x 15 cm. She had no personal history of previous breast disease and there was no family history of breast cancer. Our initial preoperative diagnosis was of a phylloides tumour. The patient had a total excision of her breast mass which revealed florid juvenile papillomatosis at histology. This presentation highlights the clinical presentation and imaging features of juvenile papillomatosis. The classical histopathological characteristics, unusual microscopic findings and management of a huge-sized tumour in an adolescent Nigerian patient are also presented.

Unusual case of cellulitis due to primary cutaneous histoplasmosis

A 63-year-old white man with a history of rheumatoid arthritis on adalimumab was admitted to the hospital for left arm swelling and erythema. On physical examination, the patient was afebrile and non-toxic appearing and there was tense oedema of the left forearm. Initial laboratory work was unremarkable except for elevated inflammatory markers. MRI of the arm showed non-specific findings of inflammation. The patient was started on empiric antibiotics but did not improve. Given the patient's immunosuppression, early consideration was given to fungal or mycobacterial causes. Initial serum fungal studies were negative and the patient was taken for diagnostic local incision and biopsy of the left volar forearm. Grocott's methenamine silver and periodic acid–Schiff staining revealed fungal organisms resembling Histoplasma and intraoperative fungal cultures grew Histoplasma capsulatum confirming the diagnosis. The patient was treated with a 6-month course of itraconazole with improvement in his condition and eventual complete resolution.

Case of a missed airway stent migration

This case report describes a rare complication to stent management of airway compression. An 84- year-old man was admitted to the outpatient clinic with haemoptysis, cough and dyspnoea. A CT scan showed an intraluminal, non-occluding tumour close to the right side of the main carina. A stent was inserted in the right main bronchus. The patient was, 7 months later, admitted to the emergency room with severe cough and dyspnoea. The stent was produced during a coughing spell. Retrospective investigation of available imaging revealed that the stent had been dislodged to a nearly 'perfect' position in the left main bronchus several months earlier which, however, had not been noticed and thus not reported by the radiologist describing the CT. The possibility of a right-left confusion should always be kept in mind, especially if a patient presents with renewed symptoms that should have been managed successfully.

hand-foot syndrome due to paclitaxel: A rare case report p. 284 Pritam S Kataria, Pradip P Kendre, Apurva A Patel, Nahush Tahiliani, Vijay Bhargav, Honey Parekh DOI:10.4103/ijp.IJP_547_17 Hand-foot syndrome (HFS) is a relatively frequent adverse reaction to certain anticancer drugs. HFS is a type of dermatitis which has been most commonly described with 5-fluorouracil and capecitabine. However, HFS with paclitaxel is rare and has been reported sparingly in the literature. A 52-year-old male patient with recurrent carcinoma of the buccal mucosa was started on palliative chemotherapy regimen, injection paclitaxel (175 mg/m2) in combination with injection carboplatin. On post-chemotherapy day 13, the patient started developing pain, dysesthesia followed by bullae formation, and desquamation over palms and soles. Clinically, the patient had Grade 3 HFS characterized by symmetrical, tender skin lesions over the dorsal aspect of palms, and soles with desquamation necessitating interrupti

It has been known to us that solar radiation contributes to photoaging. Until recently, it was thought to be due to ultraviolet rays alone. However, a growing number of evidence confirms that visible and infrared (IR) rays also contribute to extrinsic aging. Visible and IR rays account for 50% and 45% of the solar radiation reaching the earth. Ultraviolet A induces retrograde mitochondrial signal, thus leading to induction of matrix metalloproteinase. Ultraviolet B and IRC cause heat-related generation of free radicals and destruction of collagen and elastin. Exposure to visible light induces cytokines, free-radical formation, and pigmentary changes in human skin. The end result of solar radiation is generation of free radicals and ultimately oxidative damage, photoaging, and photocarcinogenesis. The present broad spectrum sunscreen does not provide complete protection of the human skin from oxidative insult. So, a combination of a sun protection factor active component along with an antioxidant is the ideal way of photoprotection. Till date, a number of antioxidants have been tried in human and animals which have shown to be an effective photoprotective agent, though few studies have failed to prove the same. Even with conflicting reports, effect of antioxidants on human skin needs to be explored more. A good study design with a large sample size in humans must be conducted as visible light and IR rays contribute significantly to photodamage.

Idiopathic guttate hypomelanosis: An overview p. 83 Indrashis Podder, Rashmi Sarkar DOI:10.4103/Pigmentinternational.Pigmentinternational_17_18 Idiopathic guttate hypomelanosis is a commonly acquired, benign leukoderma characterized by multiple, discrete round or oval, porcelain-white macules on sun-exposed areas, especially the extensor aspect of forearms and shins, sparing the face, neck, and trunk. It usually affects the geriatric population (>50 years); chronic exposure to ultraviolet rays and senile degeneration being the important pathogenic factors. The diagnosis remains essentially clinical, whereas newer confirmatory investigations are emerging. Despite the benign course of progression, many patients seek medical attention owing to cosmetic concerns. Several treatment modalities have been tried over time including topical, physical, and surgical measures, although there is lack of a standard treatment regime. In this article, we have reviewed the different aspects of this


Melasma p. 91 Rupali Dharni, Bhushan Madke, Adarsh L Singh, DOI:10.4103/Pigmentinternational.Pigmentinternational_33_17 Introduction: Melasma is a commonly acquired pigmentary disorder that manifests as symmetric hyperpigmented macules and patches on the face. Aim: To correlate Wood’s lamp and dermatoscopic findings in patients having melasma. Materials and Methods: A total of 80 patients who were clinically diagnosed with melasma were examined under a Wood’s lamp and dermatoscope, and all the findings were recorded and analyzed. Result: The degree of agreement between the Wood’s lamp findings and dermatoscopic findings was found to be substantial as analyzed by kappa statistics with K = 0.813 and P = 0.0001 (significant). Conclusion: Dermatoscopy is advocated globally as a screening and diagnostic procedure for melasma and other pigmentary disorders, especially for earlier therapeutic intervention targeting different stages and mechanisms involved in pathogenesis.


PUVASOL and NBUVB in patients with vitiligo p. 96 Vaaruni Ravishankar, Santoshdev P Rathod, Siddhartha Saikia, Raju G Chaudhary, Rekha B Solanki DOI:10.4103/Pigmentinternational.Pigmentinternational_39_17 Introduction: Vitiligo is an acquired, hypomelanotic disease, characterized by circumscribed depigmented macules. Phototherapy, which is the use of ultraviolet irradiation with or without exogenous photosensitizer is a well established treatment option. Psoralens with sunlight as the source of ultraviolet A-rays is known as PUVASOL. Narrow band Ultraviolet B phototherapy (NBUVB; 311–313 nm) has been introduced over the past decade. Aims: To study the clinical effectiveness and assess the safety of NBUVB and PUVASOL therapy in Vitiligo patients. Methods: The patients were randomly allocated in to two groups containing 25 patients each. Group A patients received NBUVB with an initial dose of 250 mJ/cm2, incremented by 20% with each subsequent visit till optimum dose was achiev


Actinic keratosis in vitiligo after oral PUVAsol therapy with review p. 103 Saumya Sankhwar, Sunil K Gupta DOI:10.4103/Pigmentinternational.Pigmentinternational_2_18 Abstract Vitiligo is an acquired disorder characterised by depigmentation. The etiopathogenesis is still unclear and many theories have been proposed for the same. It is believed that due to lack of protective melanin, a vitiliginous patch is more prone to photodamage by UV radiation and development of skin cancers especially following PUVASOL therapy. But, few cutaneous malignancies have been reported and even fewer cases of actinic keratoses have been reported over a vitiliginous skin. Here, we report a case of elderly female who developed actinic keratoses over longstanding sun exposed vitiliginous skin post PUVA therapy.

Steroid-induced perilymphatic hypopigmentation: Response to tacrolimus p. 114 Sneha Ghunawat, Rashmi Sarkar DOI:10.4103/Pigmentinternational.Pigmentinternational_11_18 Intralesional steroids are commonly used in dermatological practice. This route of administration has the advantage of minimal side effects. However, other adverse reactions namely local atrophy, ulceration, infections, etc. have been noted. One peculiar side effect following this route of administration “steroid-induced perilymphatic hypopigmentation and atrophy” has been described below. Although this condition repigments spontaneously, the use of tacrolimus to fasten the response has been highlighted in the case report.

Group A patients received NBUVB with an initial dose of 250 mJ/cm2, incremented by 20% with each subsequent visit till optimum dose was achieved, twice a week on non-consecutive days. Group B patients received PUVASOL-oral Trimethylpsoralen or topical 0.2% w/w Trioxsalen followed by exposure to sunlight, twice a week on non-consecutive days. The extent of repigmentation was documented at regular intervals upto 6 months. Results: Amongst patients receiving NBUVB and PUVASOL, 56% and 48% had ≥50% repigmentation respectively. Disease was unstable in 48% and 36% of patients prior to commencement of therapy which reduced to 12% and 16% after therapy, respectively. 16% and 36% of the patients experienced side effects and 76% and 48% showed excellent colour match of the repigmented patches respectively. Conclusion: While both PUVASOL and NBUVB are both good therapeutic options; NBUVB therapy is found to be more effective and more cosmetically acceptable, with better colour matching of lesions and minimal adverse effects.

DOI:10.4103/ijp.IJP_74_17  
OBJECTIVES: This study was aimed to investigate the effect of aqueous cranberry extract (ACE) on MK-801-induced psychosis in mice.MATERIALS AND METHODS: MK-801-treated mice were administered ACE (1 and 2 g/kg, p.o.) for 14 days. Various behavioral parameters and neurochemical estimations such as dopamine (DA), 5-hydroxytryptamine (5-HT), norepinephrine (NE), gamma-aminobutyric acid (GABA), glutamate, and glycine as well as markers of oxidative stress such as nitrite levels were measured.RESULTS: Psychosis-induced mice showed a significant elevation of immobility time in forced swim test, locomotor activity, and reduction in time of permanency in rota-rod test, escape latency time in Cook's pole test while treatment with ACE showed a significant alteration in above-mentioned behavioral parameters in MK-801-induced psychosis. Moreover, MK-801-induced psychosis in the mice showed a significant increase in DA, 5-HT, and NA levels and decrease in GABA, glutamate, and glycine levels in the brain. In contrast, treatment with ACE at both doses remarkably altered the neurochemical parameters. In addition, ACE-treated mice showed a substantial reduction in acetylcholinesterase, D-amino acid oxidase enzyme activity, and nitrite levels which were elevated by the administration of MK-801. CONCLUSIONS: Treatment with ACE once for 14 days (1 and 2 g/kg) significantly ameliorated the behavioral symptoms in experimentally induced psychosis by virtue of neuromodulation and decreased oxidative stress.

DOI:10.4103/ijp.IJP_250_18  
CONTEXT: Postoperative sleep and circadian rhythm disturbances were associated with prolonged postoperative convalescence, respiratory, and cardiovascular morbidity. Sleep disturbances have been shown to be due to decreased levels of circulating melatonin after surgery. If this sleep pattern and circadian rhythm are recycled, outcome after surgery could be improved. AIMS: The aim of this study was to observe the effect of melatonin on the quality of sleep in patients undergoing laparoscopic cholecystectomy (LC).SUBJECTS AND METHODS: Hundred patients of LC participated in this randomized, placebo-controlled, double-blind, clinical trial. Patients were randomized equally into Group A who received 6 mg melatonin tablets 45 min before sleep for 3 days after surgery and Group B who received placebo. RESULTS: Melatonin usage results in decrease in sleep latency (SL) as compared to placebo (13.6 ± 14.95 vs. 20.10 ± 16.18 min, P = 0.04). There was also increased total sleep duration (TSD) on postoperative day (POD) 1 (P = 0.004) and POD 2 (P = 0.001) in Group A. There was a decrease in daytime naps and night awakenings after surgery in Group A though it was not significant statistically. Subjective assessment of sleep on visual analog scale showed reduced sleep scores (P = 0.001 on POD 1 and 2) and decreased pain (P = 0.02 on POD 1) in Group A. Statistically significant difference was not observed in fatigue or general well-being among groups. CONCLUSIONS: Results in this study could demonstrate that melatonin as a single agent could improve the quality of sleep after LC by decreasing SL and increasing TSD.

DOI:10.4103/ijp.IJP_36_17  
OBJECTIVES: Over the past three decades, numerous studies have focused on the biological activities of oligomeric proanthocyanidins (OPCs) in the prevention of many diseases such as neurodegeneration, atherosclerosis, tumorigenesis, and microbial infections. OPC has redox-active metabolites which could modulate the intracellular redox equilibrium to maintain the antioxidant homeostasis. This redox-modulating efficiency of OPC could provide new insights into therapeutic approaches that could reduce the burden of cardiovascular diseases. The main objective of this study was to explore the biological and metabolic activities of OPC using in silicoapproaches. METHODS: To validate the above objective, chemoinformatic tools were used to predict the metabolism of OPC after ingestion, based on both the ligand and structure of the constituent compounds. RESULTS: OPC showed possible sites for Phase I metabolism by cytochrome P450, and the metabolites obtained thereafter may be responsible for its biological activities. Absorption, distribution, metabolism, elimination, and toxicity properties showed efficient absorption, distribution, and metabolism of OPC, without toxicity. CONCLUSION: Thus, from the results obtained, OPC could be strongly recommended as a cardioprotective drug.

Kaushik Mukhopadhyay, Parasar Ghosh, Partha Ghorai, Avijit Hazra, Amal Kanti Das
DOI:10.4103/ijp.IJP_633_16  
OBJECTIVES: To assess efficacy and safety of oxaceprol, a hydroxyproline derivative with putative mechanism of action different from traditional nonsteroidal anti-inflammatory drugs, in symptomatic knee osteoarthritis, in comparison to tramadol. MATERIALS AND METHODS: A parallel group, double-blind, randomized controlled trial was conducted with ambulatory patients over 50 years age suffering from knee osteoarthritis causing pain of at least moderate intensity. Patients were randomized to receive either oxaceprol 200 mg thrice daily or tramadol 50 mg thrice daily for 12 weeks. The primary efficacy variable was symptom relief as assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) version 3.1 for pain, stiffness, and physical function. Responder rate (50% pain relief), patient's Clinical Global Impression (CGI), and rescue medication use were other outcomes measured. Vital signs, routine blood counts, tests of hepatorenal function and treatment-emergent adverse events were recorded for safety assessment.RESULTS: From 91 patients recruited, 43 on oxaceprol and 36 on tramadol were evaluable. The WOMAC scores declined significantly from baseline in each arm but remained comparable between groups throughout the 12-week study period. The CGI ratings and 50% responder rates were also comparable at the final visit. Differences in dose up-titration and rescue medication requirements were statistically nonsignificant. So also were the adverse event counts. Compliance was satisfactory in both groups. CONCLUSIONS:Efficacy and tolerability of oxaceprol were comparable to tramadol, and the drug can be considered as an alternative to low-potency opioids in the management of knee osteoarthritis.

INTRODUCTION: Adverse drug reaction (ADR) is a public health problem which constitutes one of the leading causes of morbidity and mortality worldwide. In India, only a few studies reported cancer chemotherapy-induced ADRs. The objectives of the present study were to assess the organ system involved, frequency, severity, and preventability of the ADRs occurred. MATERIALS AND METHODS: Data on ADRs of retrospective cohorts were extracted from the filled ADR forms received from the department of radiation oncology. Descriptive statistic was used to summarize and analyze the available data, namely patient demography, causality, severity, and preventability of the event. RESULTS: A total of 191 chemotherapy-induced ADR reports were received from 164 patients during the period March 2015 to August 2017. Almost three-fourth of the ADRs occurred in patients who were receiving regimens involving multiple drugs. Taxanes, alkylating agents, and platinum compounds were the common drug groups involved. The skin (n = 90) was the most frequently involved organ with alopecia and hyperpigmentation as most common manifestations. The severity (Hartwig and Siegel) and preventability scales (Modified Schumock and Thornton) indicated that most reactions were mild (54.45%) in nature and the majority of them were preventable. More than two-third (69%) of the reactions were related "possible" to the suspected drug as determined by the World Health Organization causality assessment. CONCLUSION: Chemotherapy-related ADRs among cancer patients are worrisome. It has a negative impact on patient quality of life and in addition increases cost of therapy. It is found that timely reporting of chemotherapy-related ADRs and having an effective ADR monitoring system in place ensure preventability of the ADRs in many cases. Oncologists, Radiotherapists and Onco-surgeons should be actively involved in ADR reporting (Onco-Pharmacovigilance) and exchange constructive information, update and educate each other about appropriate use of anticancer drugs. Onco-pharmacovigilance is the need of the hour and could be of immense value in reducing morbidity and mortality if practiced with utmost importance.

OBJECTIVES: Currently, recommended high-dose oxytocin regimen for the prevention of postpartum hemorrhage (PPH) following cesarean delivery (CD) is associated with maternal side effects frequency of which is greater with a higher cumulative dose and rapid administration of oxytocin. Here, we evaluated the efficacy of single-dose intravenous oxytocin over 2–4 h (total = 10 units) with oxytocin maintenance infusion for 8–12 h (total = 30 units) in postoperative CD women for the prevention of PPH. METHODS: The current double-blinded randomized controlled trial was carried out in a tertiary care institute in Southern India. The primary outcome measures included the following: (a) the need for additional uterotonics to control PPH and (b) significant deterioration of vital signs as assessed by pulse rate and blood pressure in the postoperative period. The secondary outcome measures were as follows: (a) significant difference (≥10% between preoperative and postoperative packed cell volume) and (b) need for blood transfusion. RESULTS AND CONCLUSIONS: Two hundred and seventy-one women were randomized into Group A (oxytocin = 10 units; n = 135) and Group B (oxytocin = 30 units; n = 136). Both the groups were comparable with regard to demographic characteristics. There was no difference in any of primary or secondary outcome measures in the two groups. Thus, low-dose oxytocin regimen is as effective as high-dose oxytocin regimen in the prevention of PPH in postoperative CD women.

DOI:10.4103/ijp.IJP_547_17  
Hand-foot syndrome (HFS) is a relatively frequent adverse reaction to certain anticancer drugs. HFS is a type of dermatitis which has been most commonly described with 5-fluorouracil and capecitabine. However, HFS with paclitaxel is rare and has been reported sparingly in the literature. A 52-year-old male patient with recurrent carcinoma of the buccal mucosa was started on palliative chemotherapy regimen, injection paclitaxel (175 mg/m2) in combination with injection carboplatin. On post-chemotherapy day 13, the patient started developing pain, dysesthesia followed by bullae formation, and desquamation over palms and soles. Clinically, the patient had Grade 3 HFS characterized by symmetrical, tender skin lesions over the dorsal aspect of palms, and soles with desquamation necessitating interruption of treatment. Therefore, this case has been presented to be cognizant with this rare form of side effect with one of the most commonly used drug in oncology.
